INTRODUCTION

This TERMS OF REFERENCE for the ESIA scope and contents of the investment proposal „Construction of NABUCCO Transit Gas Pipeline - Project on the Territory of the Republic of Bulgaria”, was prepared in compliance with the requirements of Art.95 of the Environmental Protection Act (EPA, promulgated in Official Gazette 91/ 25.09.2002, amended and complemented in Official Gazette 103/ 29.12.2009) and the requirements of Art. 10, par. 3 of the Ordinance on the terms and procedures for carrying out an Environmental Impact Assessment (Official Gazette 3/2006, amended and complemented in Official Gazette 29/ 16.04.2010). The pipeline route is considered within a 500-meter wide corridor.

The investment proposal is a subject of mandatory ESIA as it comes under the provisions of Annex 1 of Bulgarian Environmental Protection Act (EPA). In addition the requirements for impacts in trans-border context (Espoo Convention) will be observed, as well as the requirements of the European legislation (and more specifically Directive 85/337/EEC, amended and complemented with Directive 97/11/EC and Directive 2003/35/EC, including everything related to trans-border impact).

As long as the Bulgarian law requires the performance only of an EIA, the LFE Chimcomplect focuses also on the social significance of the gas pipeline, as well as on the best international practice (especially the requirements of IFC (International Financial Corporation), which support the Equator principles and the policy of the World Bank). For that reason the principal intends to present a broader in its scope Environmental and Social Impact Assessment - ESIA.

The ToR for determining the scope, the contents and the form of the EIA Report for investment proposal Nabucco Gas Pipeline was worked out on the grounds of the answer of MOEW to the Notification of the project submitted by the principal, to the Ministry of Environment and Water (MOEW) (Letter Ref.No. НГПБ-04-00-12/03.06.2009 , entry Ref No. ОВОСУ-7720/04.06.2009) with presented additional information to the Notification with letter Ref.No. НГПБ-04-00-30/14.07.2009 and answers of the MOEW (Ref.No. ОВОСУ-7720/01.07.2009 and Ref.No. ОВОСУ-7720/02.09.2009).

Competent authority for deciding on the EIA is the Minister of Environment and Water – Annex 3.

1. PROJECT OVERVIEW

The Nabucco natural gas pipeline constitutes a dedicated gas transit and transportation pipeline from Turkey to Austria via Bulgaria, Romania and Hungary. The aim is to create a pipeline system for natural gas transmission from different sources in the Caspian Sea Region and the Middle East to Central Europe.

The Nabucco natural gas pipeline off-takes for national gas grid and underground gas storage will be provided to the national gas grid in the five transit countries involved and can further be connected to underground gas storage along the route either directly or via national gas transportation networks.

The Nabucco Gas Pipeline International GmbH is owned by the national gas transmission companies such as BOTAS, Bulgargaz Holding, Transgaz, MOL, OMV and RWE.

On the territory of Turkey, Bulgaria, Romania, Hungary and Austria Nabucco Gas Pipeline International GmbH has established local companies, which on behalf of the company are principals for the project NABUCCO in each of these countries. On the territory of Bulgaria Nabucco Gas Pipeline Bulgaria Ltd. is subsidiary 100% owned by Nabucco Gas Pipeline International GmbH.

The Project will be designed and constructed in Stages leading up to a High Flow Case of 31bNcm/yr.

On 14.07.2009. Nabucco project was declared the subject of national importance on the territory of Bulgaria (Decree № 616).

This current FEED study is concerned with Curent stage of the Project, although aspects of the design such as the overall hydraulics design will consider all stages.

This ToR refers to the design of the route, developed in a 500-meter corridor within territory of Bulgaria, within which will be situated the pipeline route, with an easement and working stripe projected to be 36 m. wide and in forrest areas – 30 m

1.1.1. Description of the project

1.1.1.1. Design sectors of the preferred gas pipeline route

In 2004, with Employer CBI John Brown Limited, and at the stage of technical feasibility study, a study was carried out for selecting a route for the Nabucco gas pipeline on the territory of Bulgaria, the so-called TFS route. This study marked the general direction of the Nabucco gas pipeline, and its entry and exit points were coordinated with Turkey and with Romania. It should be noted, that the Natura 2000 European network did not exist in the years of this study.

In 2009 a review of the TFS route was started, with the selection of a new preferred route, in the light of the new legal framework in Bulgaria regarding the protected areas of Natura 2000, and because of the readiness for realization of the project on part of the Principal.

The following main criteria for the pipeline route were observed in the choice of the project sectors:

- To provoke minimum impact on the environmental and social environment;

- To avoid or to pass at admissible distance form protected areas, Natura 2000 zones, natural landmarks, and where crosses them, to look for the optimal – form ecological point of view – route;

- To avoid settlements, civil and special objects and their surrounding infrastructure, mining and underground workings, quarries, studied and concession areas of minerals, etc.

- To avoid localities of archeological importance;

- To pass in possibly the most of its length adjacent to the easements of the existing pipeline infrastructure of the country;

- To pass along the relatively shortest way between its entry and exit points in Bulgaria;

- To go around the wooded and rocky areas, irrigation, drainage fields, water catchment areas, landslide areas, unstable geological areas, areas with marked erosion and other risky areas;

- To cross the Eastern Balkan Mountains in the easiest possible and engineering feasible way, and in conformity with the environmental legislation;

- To pass on the crests of the hilly and mountainous areas, while avoiding the steep terrains with large transverse and longitudinal gradients, in order to minimize the necessary construction measures;

- To exert, as practically possible, minimum impact on farming, especially on orchards and vineyards;

- To minimize the risk for the gas pipeline safety and the safety of the populated areas;

- To minimize the total cost of the project;

- To minimize the risk for safety when the pipeline crosses the area of NPP Kozloduy in the crossing of the Danube River, which is in conformity with the report „Simulation of emergency events with main gas pipeline in the area of the Danube River”, prepared by Risk Engineering PLC, 2006.

The location of the proposed gas pipeline route is shown in the attached maps (3 sheets), prepared on Administrative map in scale M 1:200 000 – Annex 1 and maps (3 sheets) of the protected areas of Natura 2000 in scale М1:200 000 - Annex 2.

The total length of the design gas pipeline route through the Republic of Bulgaria is 412 km, out of which 208 km are along existing gas pipelines and 204 km are in a standalone route (Figure 1.1.1.1-1).

The description of the route follows the sectors described in Table 1.1.1.1-1.

Table 1.1.1.1-1

Division of the gas pipeline route in sectors

Sector- from km to km Description

Sector 1km 0+000÷km 80+000

From the state border with Turkey to CS Lozenets (in Krasta Locality)Parallel to the transit gas pipeline to Turkey

Sector 2km 80+000÷km 102+870

Approach from the south to the Balkan mountain(at a road junction after the Luda Kamchia River)

Sector 3km 102+870÷km 120+844

Crossing of the Balkan mountain

Sector 4km 120+844÷km 192+513

From the Balkan mountain to the National gas pipeline – Northern ring

Sector 5km 192+513÷km 325+417

Parallel to the National gas pipeline – Northern ring

Sector 6km 325+417÷km 412+285

From the detour to the border with Romania at the Danube RiverBranching from the route of the existing National gas pipeline

The length of the sectors is determined as per the topographic peculiarities of the terrain and the presence of an existing gas pipeline infrastructure, and the coordinates of the peaks of the gas pipeline in Coordinate system 1970 are presented in Annex 4.

1.1.1.1.1. Sector 1 - from km 0+000 to km 80+000 – 80 km

This sector includes the route from the state border with Turkey till the existing compressor station CS Lozenets (4 km after it – in Krasta Locality). In this sector the route passes parallel to the existing two transit gas pipelines to the Republic of Turkey.

Kilometer 0+000 is the starting point of the gas pipeline on the territory of Bulgaria at the state border with Turkey. It is located at about 1.5 km east of the village of Strandzha, and 50 m east of the existing transit gas pipeline to Turkey. The location point of entry was coordinated with the Turkish party in 2004 and was confirmed in October 2009.

The route follows a northwest direction, crossing in succession Yambol District through the municipalities of Bolyarovo and Straldzha, and Burgas district through the municipalities of Sungurlare and Sredets, and the number of crossed village community land in the sector is 17.

From km 0+000 to km 60+000 the route descends the northern slopes of Strandzha Mountain with elevation 500÷250 m. From km 60+000 to km 75+000 the relief is flat with elevation 250÷150, and the route touches the east end of the Thracian lowland. After km 75+000 and to km 80+000 the route ascends to elevation 430 in a mountainous sector.

There are no swampy territories in this sector. High level of groundwater, affecting the trench, can be expected only in the area of the greater rivers and in the sector of km 70+000÷75+000, where an existing draining system could be find. The sector crosses 13 water courses from 5 to 30 m wide, 17 courses up to 5 m wide, and 5÷10 gullies with seasonal runoff.

The sector crosses Natura 2000 protected areas with total length of about 28 km, which cannot be avoided. For all these areas, including for the rest of the pipeline sections, will be determined an optimal route with minimum impacts and will be provided mitigation measures in the phase of project implementation.

page 15 of 156

The greatest uninterrupted sector with Natura 2000 protected areas starts from the border with Turkey and has a length of 25 830 m. It includes the protected areas BG 000219 Dervent heights 2 and BG 0002066 West Strandzha as per the two Directives for Natura 2000 network. The remaining part, about 2 km, is at the crossing of Mochuritsa River at km 65 - protected area Mochuritsa River, and at km 70 there is the protected area Straldzha, as per the Directive on Habitats, which cannot be bypassed.

There are two examples of going around (bypassing) Natura 2000 areas in this sector – at km 35÷47 – BG 0000513 Voinishki Bakadzhik and km 71÷75 and BG 0002028 Straldzha Complex, as per the EU Directive of 02.04.1979 regarding wild bird protection (79/409/EEC), where the Nabucco route leaves the corridor of the existing gas pipelines and deviates from them at about 1÷2 km distance. This detour leads to increasing the gas pipe length with about 5÷6 km.

It this sector the route crosses 8 sanitary-protective belts (belts II and III) of water sources for potable water supply at km: 0-1, 17-18, about 26 and 28, 36-37, 56-58, 58-59 and 76-78. Belt I of the water source at km 18 is located into the 500 m corridor of the pipeline route (at distance of 155 m to the central line).

At km 65 the central line of the pipeline is located at distance of 104 m from Koyadzhika deposit of aggregate minerals, which is still not subject of concession.

Crossings of above ground facilities

In the considered sector the gas pipeline crosses one motor highway – Trakya (to be constructed in the future), three main roads and nine secondary roads. On the average, the gas pipeline will cross roads with permanent pavement every 6 km of its length. All crossings of motorways are planned to be completed via a trenchless method, and the type of crossing will be specified after a detailed geotechnical report.

In the sector at km 69+495 the route crosses the main two-way electrified railway Plovdiv-Burgas. The crossing is planned to be trenchless.

The proposed route does not pass though urbanized territories, it goes around the big populated areas (the towns) at a distance about 5÷10 km away from them, and the villages – at a distance between 0.2 and 3÷4 km.

In the considered sector the route crosses several above ground high-voltage power lines (20кV).

Crossings of underground facilities

In the considered sector, from km 0+000 to km 75+000 the route passes adjacent to the underground transit gas pipelines to Turkey. Till km 58+000 the gas pipelines are two of DN 1000 and pressure 55 barg.

Till km 9+380 the route passes on the right (as per the direction of the gas flow) of the existing gas pipelines, at 35 m distance from them, in some locations this distance is up to 500 m because of topographic peculiarities and the distance from the cleaning facilities of the existing gas pipelines at CS Strandzha. At km 9+380 the route crosses the existing gas pipelines and passes onwards on their left (of the gas flow direction). At km 35+600 and km 45+565 the route again crosses twice the existing gas pipelines and remains on the left of the gas flow direction.

At km 73+560 the gas pipeline crosses an oil products pipeline (products pipeline) DN 300.

At km 74+700 the gas pipeline crosses a transit gas pipeline to Greece and Macedonia DN 700.

At km 76+484 the gas pipeline crosses the National gas pipeline – Southern ring DN 700.

Passage

The sector is easily approached, and for about 10 km medium accessible – in the border zone and at the crossings of some gullies. No additional access roads are envisaged for this sector. The connection of the construction strip to the existing road network will be done in the crossing locations –every 5÷6 km in average.

1.1.1.1.2. Sector 2 - from km 80+000 to km 102+870 – 22.870 km

This sector comprises the route from compressor station CS Lozenets (4 km after it, in the Krasta locaty) till the road village Vezenkovo – village Velislav, at the crossing of Luda Kamchia River. The direction of the route is to the north and it crosses Burgas District through Sungurlare municipality. The number of crossed village community land in the sector is 5.

The elevation above sea level is 450÷200 m. At the end of the sector is the line of the southern outskirts of the Balkan mountain, from where it starts to rise.

The sector crosses: Mochuritsa River at km 88+100, Luda Kamchia River at km 102+800, 3 canals with width of up to 5 m, and 5÷6 gullies with seasonal runoff.

Crossings of above ground facilities

In the considered sector the gas pipeline crosses three secondary roads. The gas pipeline will cross roads with permanent pavement every 7 km on the average. All crossings are planned to be trenchless.

No railway lines are crossed in this sector. The route crosses several high voltage above ground power lines of 20кV.

Crossings of underground facilities

At the present stage there is information about the crossing of a major water supply pipeline at km 90+000. Detailed data about the water-conduit will be provided in the technical design.

1.1.1.1.3. Sector 3 - from km 102+870 to km 120+844 –17.974 km

This sector comprises the route that crosses the Balkan mountain.

For this sector and for parts of the adjacent sectors the maximum effort was made to select a suitable route. Four options were in succession developed, compared and inspected on site. The most important considerations for the choice of the route were the topography of the sector and the minimization of crossing Natura 2000 zones.

The direction of the route is to the north; it crosses in succession Burgas District through Sungurlare municipality and Shumen District through Varbitsa municipality. The number of crossed village community land in the sector is 4.

The route gradually ascends to its highest point on Bulgarian territory – Alaborun peak with elevation 769.70 at km 111+000. Then the route passes along a narrow crest till elevation 700 at km 113+000, steeply descends to elevation 400 at km 114+000 of Echemishka River, then there is a steep ascent to elevation 600, passage along a narrow crest till elevation 680 at km 116+500, descent to elevation 400 at km 118+000 at Ravna River, ascent to elevation 550 and descent to elevation 380 at km 120+844. With this the route crosses the Balkan mountain.

In this sector the route crosses: two rivers with width from 5 to 30 m and seasonal gullies with seasonal water.

In the considered sector the route goes around and does not cross protected territories in the sense of the Act on Protected Territories – the reserve Orlitsata and the protected locality Medvenski karst. At km 105-106 in the 500 m corridor Aat a distance of 180 m to the central line of the pipeline route) is located belt I of the sanitary-protective zone of a water source for potable water supply.

The route in this sector does not cross protected areas of Natura 2000.

Crossings of above ground facilities

There are no roads of the national road network in the considered sector.

Crossings of underground facilities

There are no crossings of underground infrastructure in the considered sector.

Passage

The sector is hard to access, the nearest road on the north is at km 124+000, and on the south – at km 103+000. Roads with stone pavement can be used to access the route from the west with length of about 6 km and from northeast with length of about 10 km. The two roads meet in the middle of the considered sector. From there the access for the construction machines can be secured only along the construction strip.

1.1.1.1.4. Sector 4 - from km 120+844 to km 192+513 – 71.669 km

This is the sector of the route from the Balkan mountain to the national gas pipeline – Northern ring.

For this and for the previous sector 3 the maximum effort was made to select the suitable route. Four options were in succession developed, compared and inspected on site. Leading considerations for the choice of the route were the topography of the sector and the minimization of crossing Natura 2000 zones.

The route follows a northwest direction, crossing in succession Shumen District and Targovishte District, and the municipalities Varbitsa, Omurtag, Targovishte and Popovo. The number of crossed community lands in the sector is 26.

In this sector the route crosses two of the bigger rivers: Golyama Kamchia River at km 132+750 and Popovska River at km 188+625. The route also crosses 14 water courses with width from 5 to 30 m.

At the beginning of the sector the route crosses a Natura 2000 area for a length of about 11.5 km, which cannot be bypassed. It is the protected area Kotlenska Mountain as per the Birds Directive. The territory occupies arable land – cornfields.

At km 189 the pipeline route crosses belts II and III of the sanitary-protective zone of water source for potable water supply.

At km 160-162 the central line of the route is at a distance of 40-450 m to Tsvetnitsa deposit of aggregate minerals (free deposit, not granted for concession).

About km 187 the central line of the route is at distance of 1600 m to Karierata-Popovo deposit of aggregate minerals, subject to granted concession.

Crossings of (above) ground facilities

In this sector the route crosses 3 main roads and 11 secondary roads.

At km 183+515 the route crosses the main two-way electrified railway Sofia-Varna. The crossing is planned to be trenchless.

Along the entire length the route crosses multiple air powerlines, the exact location of which will be specified in the next stages of the project. In the considered sector the route crosses several air powerlines of 20 kV.

Passage

The sector is easily approached. No additional access roads are envisaged.

1.1.1.1.5. Sector 5 - from km 192+513 to km 325+417 – 132.904 km

This sector includes the route that passes in a common corridor with the route of the existing National gas pipeline – Northern ring. Along its entire length Nabucco gas pipeline route passes parallel to and in the immediate vicinity of the National gas pipeline route. Only from km 220+000 to km 226+200 it deviates at average 800 m south of the National gas pipeline route in order to go around (by pass) Natura 2000 zones.

The route follows a direction to the west, crossing in succession Targovishte District through the municipality of Popovo, Ruse District through Byala municipality, Veliko Tarnovo District through municipalities Strazhitsa, Polski Trambesh and Pavlikeni, Pleven District through municipalities Pleven and Levski, and Lovech District through municipalities Letnitsa, Pordim and Lovech. The number of crossed community lands is 30.

From the beginning of the sector till km 234+680 the route passes south of the National gas pipeline. At km 234+680, after the crossing of Yantra River, the route crosses the National gas pipeline and passes on its northern side, going around the compressor station Polski Senovets. The route crosses the National gas pipeline in another two locations - at km 245+935 and km 249+650. These crossings are caused by the necessity to conform to the legal provisions about the distance of gas pipelines from settlements.

At km 325+417 the route deviates to the north as a standalone route. Its elevation is from 350 to 100 m.

In the sector the route crosses two major rivers with width over 30 m – Yantra River at km 234+250 and Osam River at km 279+800, 6 water courses with width from 5 to 30 m, 33 courses with width up to 5 m, and 12 seasonal gullies with water. The rivers will be crossed using the open cut method.

At km 277+500 and km 323+000 the route crosses Natura 2000 areas with total length of about 2.8 km, located perpendicular to the route, so they cannot be bypassed.

Protected locality (PL) Taraklaka is in the 500-meter corridor, at a 100-meter distance from the central line of the route.

At km 224-225 and km 225-227 the route crosses belts II and III of sanitary-protective zones of water sources for potable water supply.

At km 280-282 the central line of the route crosses Gaslika deposit of aggregate minerals (still not subject of concession).

Crossings of (above) ground facilities

In the considered sector the route crosses 3 main roads and 17 secondary roads.

The route crosses 3 railway lines: at km 236+005 – electrified single railway Ruse-Podkova, at km 271+400 – the major electrified double railway Sofia-Varna, and at km 283+415 – the single railway Troyan-Belovo. Trenchless crossing is envisaged.

In the considered sector the route passes under several 20kV above ground powerlines.

Crossings of underground facilities

In the whole sector the route passes in immediate vicinity along the existing underground National gas pipeline. The minimum distance of 35 m between the nearest existing pipeline and Nabucco pipeline has been coordinated with the owner of the transit gas pipelines Bulgartransgaz PLC. In this sector the route crosses 3 times the National gas pipeline - at km 234+680, km 245+935 and km 249+650.

At this stage there is no data about the crossing of other underground communications. Detailed information about other crossings will be provided with the Technical design.

Passage

The sector is easily approached. No additional access roads are envisaged. The connection of the construction strip with the existing road network will be realized at the locations of the crossings – every 5÷6 km in average.

1.1.1.1.6. Sector 6 - from km 325+417 to km 412+285 – 86.868 km

This is the sector of the route that branches from the common corridor with the National gas pipeline (west of the village of Nikolaevo) and passes to the northwest to the Danube River and the border with Romania.

The route crosses in succession Pleven District through the municipalities Pleven, Dolni Dabnik, Iskar, Dolna Mitropolia, and Vratsa District through the municipality of Oryahovo. The number of crossed community lands is 14. Along its entire length the gas pipeline follows a standalone route beside dirt roads. At km 411+680 the route reaches the bank of the Danube River at medium water level; km 412+285 is at the border with Romania, which is in the riverbed.

In this sector the route crosses four big rivers over 30 m wide – Vit River at km 341+200, Iskar River at km 372+250, Gostilya River at km 377+190 and Ogosta River at km 411+200. The rivers Vit, Iskar and Gostilya will be crossed with open cut method, and Ogosta River – using a trenchless method (HDD).

From km 341+500 to km 364+000 the route passes through irrigated fields with a multitude of irrigation canals (reveted and non-reveted), 13 of them with width of 5÷30 m and two up to 5 m wide.

The route crosses Natura 2000 zones for a total length of about 4.970 km. These are the protected zones of the Directive on Habitats – Studenets (which is also under the Directive on Birds), Vit River, Iskar River and Ogosta River. The last zone cannot be bypassed because it is connected with the location of crossing the Danube River, this location is chosen in view of the avoiding crossing active landslides in the region, and is coordinated twice with Romania – in 2004 and 2009.

Crossings of (above) ground facilities

In the considered sector the gas pipeline crosses three main roads and nine secondary roads.

The gas pipeline will cross permanent pavement roads every 6 km on the average. All road crossings are planned to be trenchless, and the type of crossing will be specified after a detailed geotechnical report for the specific crossing location.

At km 352+195 the route crosses the main electrified double railway line Sofia-Varna. The crossing is planned to be trenchless.

In the considered sector the route crosses several 20kV above ground powerlines.

Crossings of underground facilities

No crossings of underground facilities are studied at this stage.

Passage

The sector is easily approached. No additional access roads are envisaged. The connection of the construction strip with the existing road network will be realized at the locations of the crossings – every 5÷6 km on the average.

There is a problematic location in the considered sector – at the bank of the Danube River.

The bank of the Danube River is at elevation of about 25.00m. Almost every year during high water the river reaches a water level of about 31.00m, flooding all adjacent terrains. Therefore, all future facilities related to the gas pipeline will be constructed at 32.00m level, which is the level of the protective dyke of the river in this area.

The crossing of the Danube River is envisioned for design in the Romanian part of the Nabucco project.

The plans are to construct a technological road and a bridge over Ogosta River in the initial stage of construction for the requirements of the horizontal directional drilling (HDD) of the Danube crossing.

1.1.1.2. Facilities related to the gas transporting system in present stage

In order to support the functioning of the gas pipeline, the following technological items and facilities are planned to be set up on Bulgarian territory:

Gas metering stations (GMS) – 2 units. The main Nabucco gas metering station of the flow of natural gas passing through Bulgarian territory will be located in the land of Oryahovo municipality. Second GMS one with a smaller capacity will be set up near the existing compressor station CS Lozenets from the transit system to Turkey, Greece and Macedonia.

Gas pipeline pigging stations (PS) – 2 units. The project envisions the set up one station for cleaning the gas pipeline on the territories of Omurtag town and second one, which will be combined with the gas metering station in the land of Oryahovo municipality. The stations will have Pig launchers/Reciver installations. At present stage will be constructed the respective block valve facility only.

Off-take station (OS) – 1 unit. One OS is planned to be built near the existing CS Lozenets of the transit gas pipeline to Turkey. It represents block valve facility with gas metering station.

Block valve stations (BVS) – 14 units. The block valve stations will be located along the pipeline dividing it in sections (at a maximum distance of 30 km from each other), equipped with devices for automatic closure in case of accident.

The location of the separate technological facilities for the gas pipeline is identified in the overall scheme of its entire development on the territories of the countries that it will cross. Some of the technological facilities are united on common sites in order to combine the servicing, the security and the use of one common infrastructure.

Stop valves (Valve stations)

According to the requirements of the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas, as well as of BSS EN1594 “Systems for gas supply. Pipelines for maximum operating pressure over16 bar - Functional requirements, the gas pipeline is divided into sections via stop valve units (block valve stations) with guaranteed physical protection by fencing.

Figure 1.1.1.1-1 Pigging station Figure 1.1.1.1-2 Gas metering station

The distance between the block valve stations is defined as per the operating conditions of the pipeline, namely: pressure and diameter, terrain conditions – earthquake zone, landslide areas, class of location of the pipeline with regard to settlements, residential areas and standalone items, the time necessary for reaching the location of the block valve stations and the need of block valves for operational purposes.

The distance between the block valve stations cannot be greater than 30 km, as per the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas.

The block valve stations dividing the pipeline in sections are planned to have underground shaftless installation, with above ground controls of the valve and a device for automatic closure in case of accident of the specific section. The devices for automatic closure of the valve should secure closure in 1 to 3 min in the case of a drop in the pipeline pressure of 10-15% from the operational pressure.

The movement mechanism of the block valve is normally hydro-pneumatic with pneumatic control. At the same time the option is envisioned for distant control and gathering of telemetric information (P, P, T C), via a SCADA system.

At every block valve station a system of a bypassing installation is envisaged, as well as a pipeline for leading the gas through a blow-off pipe.

The system of execution and management of the linear block valve stations provides safety against environmental risk and operation conditions in which no disruption is allowed in the gas pipeline operation.

Blow-off pipes

At the two ends of the gas pipeline section, before and after the block valve stations, blow-off pipes are mounted for the blow-through of the gas pipeline, at a distance not less than 15 m of the block valve inforcement.

Additional linear block valve stations

Additional linear block valve stations along the gas pipeline, as per the provisions of the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas are envisaged in the following cases:

On the two river banks at the crossing of the Danube River;

At the beginning the off-take station near Lozenets (integrated within the site)

The gas pipelines and the block valve stations under pressure – bypasses, blow-off pipes lines and connections, are constructed and installed underground with valves for shaft-less installation. It is mandatory to provide access only to the mechanism for moving the stoppage inforcement.

Gas pipeline Pigging stations.

Sites for Pigging stations are planned to be set up along the gas pipeline where there is a gas metering station (in the area of Oryahovo). At these sites there will be facilities for Pig launchers/Receiver installations for PIG cleaning, separating and diagnostic devices.

The Pigging stations will include:

Pig launchers/Receiver installations;

Pipelings, valves and Blow-off pipes;

A unit for collecting and leading out the products of the gas pipeline cleaning;

Mechanisms for taking out, moving and setting in place the PIG cleaning device in the PIG launcher/receiver;

Signalling devices (Pig passage indicators) for the passage of the PIG cleaning and inteligent device;

Local and/or remote control panel.

The unit for receiving the products of the gas pipeline cleaning is a separate underground pipeline collector with a maximum volume of 500 m3, depending on the pollution of the gas and the established cycle of cleaning the gas pipeline.

The collector unit for receiving the products of cleaning the gas pipeline is provided with the possibility for leading away the liquid phase and the slime for secondary use or for burning.

To the gas cleaning stations are mounted blow-off pipes with the same operating conditions as for the block valve stations. The approximate volume of the gas emitted in the air during the blow-through of a launcher/receiver chamber is 5000 Nm3 for the time of the procedure.

The activities for cleaning the gas pipeline are executed without polluting the adjacent terrains. The gas emitted in the air is lighter than air and is easily dispersed in the air space.

1.1.1.3. Design data

It is planned to use steel pipe with diameter Ø1422 mm (56”) for the gas pipeline.

Design pressure DP = 100 barg.

The minimum and maximum project temperature is –30°С and +50°С, respectively.

For the underground pipelines and facilities the calculations will be based on 0°С preliminary minimum project temperature.

The maximum design speed of the gas flow in the pipeline will be 12 m/s.

1.1.1.4. Characteristics of the natural gas

The survey conducted (Doc No. 70223-EG-DAT-PR-0001) provided the following two characteristics and properties of the natural gas - Table 1.1.1.3-1, Table 1.1.1.3-2.

The characteristics of the composition (1) are used in all design purposes and (2) – in the so called gas sensitivity analysis, e.g. the analysis of the types of costs for the gas transport, financial and investment analyses, the so-called “fuel switch” analyses – determining the amount of carbon emissions saved when switching to natural gas fuel, etc.

1.1.1.5. Safety measures for the gas pipeline

1.1.1.5.1. Tensions in the pipe

The gas pipeline, depending on the terrain, installation and operation conditions, will be checked for enduring forces of:

Internal pressure; Elastic bending; Loads from anchoring or landfilling the gas pipeline, and from the traffic; Loads during test of the gas pipeline and loads from the mass of water; Pushing force against floating up of the pipeline to the surface; Loads from landslide processes; Seismic pressure for the respective region; Heat expansion; Soil erosion.

The calculation comprise analysis of the loads and shifts, as well as analysis of the tensions/strains and deformations which can occur. The type of analysis and the weight of each of the above factors depend on the complexity of the project and the physical parameters of the gas pipeline sector.

As a result of the performed analyses and calculations, the thickness of the gas pipeline wall is determined so as to take the tensions of the inner pressure of the gas and the expected external loads and tensions, to which the pipeline will be subjected during its operation, as per items 7.2 and 7.3 of BSS EN1594 “Systems for gas supply. Pipelines for maximum operating pressure over16 bar- Functional requirements.”

1.1.1.5.2. Mechanic protection

The pipeline crossing of railway lines and motor roads is executed by placing the pipeline in a protective coat of steel pipe, with length and depth of laying complying with the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas.

A ventilation pipe (vent) is mounted on one end of the protective coat. The vent is brought out at least 5 m above the level of the terrain, ensuring proper dissipation of eventual gas leakages. The gas pipeline is placed in strong, well compacted soil, and crossing of railroads and motor roads in their landfill trapezium is not allowed.

When the pipeline crosses a river, the location of crossing is selected on straight sectors of the river, stable against the water current, with sloping banks that do not wash away, and at minimum width of the flooded (during high waters) riverside strip. When the gas pipeline is laid underwater the sectors within the flooded strip and those crossing swamps and high groundwater are secured against floating up. This is done with weights of reinforced concrete, with mass calculated to counter the pushing up force of the water.

When selecting a route, one should comply with the requirement to avoid landslide areas. When passing through landslide areas the gas pipeline is laid under the sliding plain of the earth mass, or above the surface, on pillars with foundations below the sliding plain.

All possible cases of additional loads are considered and accounted for, depending on the specific conditions of the gas pipeline sectors along the route.

The gas pipeline is fortified, anchored and the trench backfilled in such a way that it does not change its position during operation, with the exception of the admissible shifts from loads and temperature expansions.

1.1.1.5.3. Cathode protection

The underground and underwater parts of steel gas pipelines are protected via an anti-corrosion coating, performed in factory conditions in compliance with the requirements of BSS EN 12068-1 „Cathode protection. External organic insulation for protection from corrosion of underground or underwater steel pipelines, used together with cathode protection. Ribbons and shrinking materials”, for external coatings and active electro-chemical protection (cathode protection).

The anti-corrosion protection of the gas pipeline should have good mechanic and electric properties with regard to the environment (the type of soil) and the operating conditions. It should connect firmly to the pipe, be resistant to biological impacts and provide electric insulation.

The section of the pipeline with cathode protection should be electrically uninterrupted and should have adequate longitudinal conductivity. The electro-chemical protection is performed by the “cathode-anode” system, connected to a direct current source (cathode station). The electro-chemical protection provides resistance to the impacts of eventual high-voltage cabels which may happen to be in the vicinity of the pipeline.

1.1.1.6. Management and control

The general control system will be based on the control of the gas pressure and the flow in the pipeline system. The necessary amounts of gas in the pipeline system will be determined in advance following procedures of orders from the customers as per their purchase agreements.

The measurement facilities will be installed in the preliminary identified locations along the pipeline.

The pipeline and the system will be monitored and controlled by the main control center (MCC), located in Turkey. A backup of MCC for monitoring and control of the whole gas pipeline system Sub Control Center (SCC) will be located in Baumgarten, Austria. In-Country Control Centres (ICCC) will be located in Bulgaria, Romania and Hungary, with the facilities for monitoring the pipeline system within that Country.

SCADA (supervisory control and data acquisition) and Telecommunications Systems will be installed to support the operation and control of the complete pipeline. The control system will be independent of the ESD and F&G systems.

1.1.1.6.1. SCADA system

The primary function of the SCADA system is to provide the operational interface to support the operation of the complete gas pipeline system. The SCADA system shall acquire operation conditions of the pipeline and the above ground facilities related to the gas transporting system, remotely controls their status, displays abnormal or alarm conditions, issues online warnings and hard copy reports.

Although the SCADA system will be designed for remote operation, local conventional control tools will also be provided, with the purpose of securing the safe operation of the gas transporting system when the communication with the MCC is interrupted. A remote control terminal will be installed with every local center for maintenance of the equipment.

1.1.1.6.2. Emergency shut down system (ESD)

ESD systems will be installed at the metering stations to implement safe and emergency shutdown of the process and associated equipment under upset conditions. The ESD system shall be stand alone, and, with dedicated I/O will interface with the local SCADA system through dual redundant communication links. The local SCADA system will react to all alarm handling, ESD resets, etc. ESD valves shall be installed on the incoming (inlet) and outgoing (outlet) section at each metering station.

1.1.1.6.3. Telecommunications

The telecommunication system shall provide all necessary communications to and from the metering stations and control centers, both in normal and emergency situations. This includes data traffic for the SCADA system, voice communication, fax, e-mail capability and closed circuit TV signals.

1.1.1.6.4. Fire and Gas Detection System (F&G)

Fire and Gas systems will be installed at gas metering stations. Block valve equipment enclosures will be provided with fire/smoke detection, allowing the operator to initiate the appropriate fire protection and process shutdown.

The fire and gas detection system shell include:

Gas detectors, Smoke detectors (ionisation and optical), Heat detectors (electric) Flame detectors (Infra Red, Ultra Violet and combined IR/UV) Manual Alarm Call Points, Sound alarm, Visual alarm – flashing light in noisy areas.

All air intakes will include gas detectors.

Alarm signals will be transmitted to the SCADA system.

1.1.1.6.5. Security system

All above ground stations of the gas pipeline will be equipped with security systems, including intruder detection, video-surveillance against vehicle/pedestrian site entry of in the protected zones.

1.1.2.3. Requirements to the laying of the gas pipeline.

In compliance with the requirements of the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas, the minimum depth of laying underground gas pipelines with diameter greater than 1000 mm is 1 m to the upper surface of the pipe. This depth can be increased for considerations of observing the normative requirements for crossing other engineering facilities, in swampy or irrigated areas, in areas subject to erosion, when crossing water courses, etc.

A 200-meter wide territory on both sides of the notional axis of the pipeline is allocated for transport gas pipelines with pressure above 1.6 МРа (16 bar). A regime of preventive development protection is established in this strip in the meaning of Art. 10 of the Territory Development Act (TDA), with preserving the actual use of the land while limiting housing construction on it. The minimum distance of single buildings and other items to the gas pipeline is 125 m. In the case of parallel laying of a pipeline beside existing gas pipelines, the approved minimum distance between the axes is 35 m (additional requirement of the Bulgarian operator).

An easement is established within the 500 m. study area, with width of 36 m (12 m + 24 m) in farm land and 30 m (15 m + 15 m) in forest land. The minimum distance of the axes to an operating underground gas pipeline in forest land and in farm land terrains is respectively 18 m and 32 m (legal constraints) (Figures 1.1.2.3-1 and 1.1.2.3-3). The easement coincides with the

construction strip whose dimensions provide proper construction / repair works. At such manner also the affected land (construction/easement) is minimized due to overlapping.

Figure 1.1.2.3-1 Scheme for gas pipeline construction in farm land

Figure 1.1.2.3-2 Scheme for gas pipeline construction strip in forest land

1.1.2.4. Marking of the route

Underground marking

In order to avoid unintentional damage of the underground gas pipelines, when carrying out excavation and repair works the gas pipelines are marked with signal plastic marking tape, laid at least 30 cm above the upper surface of the pipe.

Above ground marking

The gas pipeline route is marked with metal or steel-concrete poles (benchmarks) set at distances providing direct visibility from one another. The minimum height of the benchmarks is 1.5 m, they are coloured at even length with yellow and black stripes. The poles are set at 2.5 m distance of the gas pipeline axis with displayed direction to it.

Labels and signs are set displaying the gas, blast, and fire risk of the surface facilities of the pipeline and of the technological telecommunication system.

In the locations where the gas pipeline crosses motor roads roadsigns are set at 150 m distance of the gas pipeline axis on both directions of the road, and at railway line crossings – at 800 m of the gas pipeline axis, with the text “Attention! High Pressure Gas Pipeline!” or other sign corresponding to the requirements for operation of the railways.

1.1.2.5. Sites of the facilities related to the gas pipeline for the present stage

1.1.2.5.1. Gas metering stations (GMS)

The site of the main gas metering station, located in the land of Oryahovo municipality has approximate dimensions 120 x 100 m - Fig. 1.1.2.5.1-1.

Figure 1.1.2.5.1-1 Development plan of GMG at Oryahovo town.

1.1.2.5.2. Off-take stations (OS)

The selected site for the envisaged for this stage inter-system connection has approximate dimensions 120 x 100 m and is located in vicinity to the existing compressor station CS Lozenets of the transit gas pipeline to Turkey.

1.1.2.5.3. Pigging stations (PS)

The Pigging (PS) Stations (2 items) 58 x 94m (for Oriahovo including metering facilities) will serve for pipe cleaning and inspection - Fig. 1.1.2.5.3-1.

Figure 1.1.2.5.3-1 Development plan of PS near Omurtag town.

1.1.2.5.4. Block valve stations

The block valve stations dividing the pipeline in sections are mounted in locations approached for service and protected from damage and intrusion. The allocated sites for the block valve stations have approximate sizes of 60 x 65 m and are surrounded by a 2.5-meter high fireproof fence.

The block valve station sites are aligned, providing the opportunity for drainage of surface water, and covered with gravel.

1.1.3. Crossings of natural and engineering obstacles.

1.1.3.1. Crossings through natural obstacles.

The natural obstacles crossed by the gas pipeline are gullies, small streams and rivers.

As regards the gullies and small streams, beside preventing floating design and increasing the depth of laying of the pipeline there are additional measures against bottom and bank erosion such as: placing rocks, bottom sills, dams, grassing and afforesting of the banks.

As regards the river crossings (see Figure 1.1.3.1-1), the selected locations are at straight stable sectors of the water course, or corrected sectors of the river. In the passage the upper surface of the gas pipeline is 0.5 m lower than the profile of the widening (flooding) of the riverbed forecast for a period of 25 years, but not less than 1 m below the level of the river bottom. The crossing is perpendicular to the dynamic axis of the river with admissible decrease (slanting) up to 60º.

The method of crossing via HDD (Horizontal Directional Drilling) can be applied eventually in the crossing of Ogosta and Danube rivers. The exact crossing method will be approved after conducting additional geotechnical surveys.

For crossings with accelerated flooding (expanding) profile the design envisages concrete bottom sills after the gas pipeline, with bank protection.

Figure 1.1.3.1-1 Pipeline crossing a river

The sectors of underwater laid pipelines, the parts within the high water levels are secured against floating up by mounting reinforced concrete weights on the pipe at specific distances, by anchoring devices or by wrapping the gas pipeline with continuous about 120 mm thick reinforced concrete coating.

Table 1.1.3.1-1 lists the crossed rivers with a description of the kilometers along the gas pipeline route, the width of the riverbed and the flooded terrace. The rivers are 27 not counting the Danube River.

(*) The survey of Danube River crossing and the crossing itself is not included in the scope of work of the Bulgarian LFE and will be realized by other party. Despite of this, the Danube River crossing will be assessed in the ESIA report.

The table does not include the small water streams and seasonal gullies, neither ground drainage canals.

1.1.3.2. Crossings through engineering obstacles.

The crossings of technical infrastructure items – gas pipelines, cabels, water pipelines, irrigation and drainage systems etc., are coordinated with the owner of the network, and performed with crossing angle at least 65º and providing the necessary clearing distance. The bigger reveted irrigation and drainage canals are crossed with horizontal drilling and casing (mantle), and the smaller ones – using the open cut method, and are restored to their initial status.

The crossings of above ground power lines (PL) are coordinated with the owners of the network, observing the requirements of Ordinance No.04/6 of 25 November 2004 on the technical rules and norms for the design, construction and use is items and facilities for transport, storage and supply of natural gas, Ordinance No. Із-1971 of 29 October 2009 on the construction-technical rules and norms for securing fire safety (Promulgated in the Official Gazette 96 of 04.12.2009, enforced since 05.06.2010) and Ordinance on the construction of electric power facilities and power distribution lines (Official Gazette 90 and 91 of 2004).

The angle of crossing will be at least 60º, and the minimum distance of the gas pipeline to the foundation of the pole at crossing and at parallel laying is from 5 m to 15 m respectively for 20 kV and 400 kV power lines.

The crossing of underground power cables and cables of the technological telecommunication network with the transit gas pipeline is at 90º angle towards the gas pipeline axis. The cables are placed in a steel pipe, the ends of which are at least 5 m away from the gas pipeline axis, as per the requirements of Ordinance No. 04/6 of 25 November on the technical rules and norms for the design, construction, and use of the items and facilities for transiting, storage, distribution and supply of natural gas.

1.1.3.3. Crossings of motor roads

All crossings of the national roads should be done via a trenchless method and coordinated with the National Agency “Road Infrastructure”, at an angle of at least 60º (Figure 1.1.3.3-1).

Figure 1.1.3.3-1 Pipeline crossing a road

The crossing locations are selected in sectors of small embankment and soil thickness. This is particularly valid for highways and roads of class I and class II, so that the crossing is done by horizontal directional drilling without stopping the traffic. Where this is not possible, the crossing is done with the open cut method with detours or temporary re-direction of the traffic along an alternative route, with coordination and development of a plan for “Temporary traffic organization”. The crossing is signalled with the respective road signs.

The depth of laying the road pavement to the upper surface of the protective mantle is 2.0 m, and to the bottom of the draining ditch is 0.5 m.

Table 1.1.3.3-1 lists the crossed roads (a total of 62) with a description of the kilometer along the pipeline route and the width of the road itself. For the planned new highways are used data submitted by the National agency “Road Infrastructure”.

1.1.3.4. Crossings of railway lines

The railway lines will be crossed via a trenchless method, and the crossings will be coordinated with Executive Agency “Railway Infrastructure” at an angle at least 70º (Figure 1.1.3.4-1).

The crossing locations are selected in sectors with small embankment and soil layer in order to carry out the crossing with a horizontal drilling without stopping the traffic. The depth of laying from the foot of the rail till the upper surface of the protective mantle of the pipeline is 2 m, and to the bottom of the draining ditch - 0.5 m. The crossing of railway lines, highways and motor roads till class III inclusive is done with a protective mantle of a steel pipe with diameter at least 200 mm greater than the nominal diameter of the gas pipeline. The ends of the protective mantle are brought out at a distance at least:

25 m of the axis of the end railway track of the railway infrastructure, 15 m from the axis of industrial railway line branches;

10 m of the edge of the roadway, but not less than 2 m of the base of the embankment.

Figure 1.1.3.4-1 Pipeline crossing a railroad

In order to provide hermetic tightness of the space between the casing and the gas pipeline, the ends of the protective mantle are fitted with cuffs. On the higher end of the protective mantle of the gas pipeline is mounted a venting pipe which is brought out at least 5 m above the terrain level and is placed at a horizontal distance:

At least 40 m of the axis of the end track of railway lines of the railroad infrastructure;

At least 25 m of the axis of railway lines of industrial railway branches and of the base of the embankment of a motor way.

Table 1.1.3.4-1 lists the crossed railway lines (a total of 6) with a description of the kilometers along the gas pipeline and the width of the railway.

1.2. Description of the main characteristics of the production process; type and quantity of main raw resources and materials

1.2.1. During construction

1.2.1.1. Above ground and underground construction

Construction in areas with arable and farm land

The greater part of the Nabucco gas pipeline route will pass through arable land and land with farm use. In order to protect the humus soil layer it is envisaged, before the excavation of the trench, to carry out selective stripping of the humus soil horizon, which after the installation of the gas pipeline will be reinstated on the surface, preserving the thickness of the layer established for the specific soil variety (see Figure 1.1.2.3-1).

The technical recultivation includes includes reverse infilling the trench, the return of the humus layer and the process of ploughing of the reinstated soil and humus layer on the working strip.

In the biological recultivation stage, different vegetation will be planted, with observing specific technological schemes; measures will be taken so as to allow to a maximum extent to restore the disturbed terrain in the area of construction and to improve the landscape of the locality.

The impaired soil and vegetation cover can successfully and in a relatively short time frame be restored by applying specific recultivation measures.

The order of performing this activity is described in the Environmental Protection Act and in Ordinance No. 26 for recultivation of disturbed terrains, improvement of poorly fertile land, stripping and using the humus layer.

According to preliminary assessments, when constructing the gas pipeline along the so selected route there will not be substantial changes in the environmental components: air, water, soil, vegetation, animal species, landscape, etc.

Construction in areas with forest vegetation

When passing through forest vegetation, the cuttings will be carefully chosen and designed with possibly smallest number of terraces and slopes. -see Figure 1.1.2.3-2.

The construction strip will be carefully cleared of chunks, stems, branches and roots of the cut trees. If necessary, the humus layer will be stripped. For example, in the brown forestsoils and the chromic podzollic soils the humus layer can be 0.25 m thick. After completing the construction of the pipeline, the deposited next to the trench humus layer should be reinstated in its clean condition on the area from which it was removed, the area will be plowed and plented with suitable grass vegetation. On a 15 m strip (Ordinance No.16 on the easements of power items, Art.20(1), item 9) on both sides of the gas pipeline it is forbidden to plant trees with a deep root system because of a risk of damaging the pipe and the respective communication cables.

The locations with possible risk of erosion processes will be precisely established, and anti-erosion measures will be conducted with constructing small size and large size fortifying facilities and draining ditches, placing rock materials, etc.

Construction of underwater gas pipeline

The crossing of river terraces and riverbeds will be in conformity with Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas – Ordinance of the Council of Ministers No.171 of 2004 (promulgated in Official Gazette 67 of 2004; amended and complemented in No. 78 of 2005, No. 32, 40 and 93 of 2006, No. 46 of 2007, No. 79 of 2008, No.5 of 2010).

The expected difficulties when constructing the gas pipeline are when crossing some gullies with steep banks and steep mountain slopes.

1.2.1.2. Construction and installation activities for the gas pipeline

The following activities are planned for the construction of the gas pipeline:

1. Marking of the site;

2. Removing trees, bushes, etc.;

3. Preparation of terraces and slopes for providing the necessary construction strip – 36 m in land with farm use, and 30 m in forest terrains or other constraints;

4. Setting up of temporary roads to the construction site and approaches to the gas pipeline route;

5. Providing water taking and water supplying facilities to the locations where water will be used and the locations of hydraulic tests of the gas pipeline;

6. Providing intermediate sites for storage and installation of pipes, facing elements, etc.;

7. Fencing off of the construction strip;

8. Separation of the humus top soil layer with storing at landfills, according to respective scheme of shaping up the construction strip. Execution is planned to be done with a bulldozer with longitudinal-slantwise movement of the machine along the pipeline route. The width and thickness of the humus layer is determined depending on the type of terrain and soil;

9. Development of the trench with a single bucket excavator, collecting the earth masses on a landfill, according to the attached scheme of the construction strip. The width of the trench is determined as a function of the depth and type of the soil, in order to avoid instability of the trench;

10. When the gas pipeline route passes through rocky terrains, there will be blasting works. Before laying the pipeline in the trench in such terrain the bottom of the trench will be backfilled with 10cm thick soil layer in order to protect the pipeline insulation from damaging;

11. After laying the pipes along the trench, there will be saddle/supports placed on the side of the trench to order and stabilize the pipes in place after their placing along the route;

12. Transporting pipes, knees and facing parts along the length of the route (the sector for mounting the gas pipeline);

13. Stringing of the pipeline next to the trench on padding (timbers not less than 150mm x 100mm)

14. Welding works (welding by a welding machine or by hand of the pipes to one another). Welding is done with internal centering devices and several layers of welding as per the envisioned welding technology;

15. 100% visual control of the welded connections;

16. 100% control using ultrasonic equipment of the welded connections (according additional instructions) or gamma-ray flow detection

17. Detail of linepipe weld joints to be coated in the field is to be adjusted in the purchase order.

An acceptable method is described below:

Field weld joints shall be protected by polyol-isocianate coating (70223-EG-SPC-CP-0011-RE-1).The coating (two pack designed for underground service) shall be applied by an automatic airless spray system on the prepared surface and appropriate/controlled environment to a min dry film thickness 1 500 microns. For coating repairs a brushable grade of the same coating type may be used.

18. Checking the quality of the gas pipeline insulation with a sparkle defectoscope along the entire length of the sector;

19. Laying the welded sector of the gas pipeline in the trench with a column of pipe laying machines (Sidebooms). The distance between the pipe-laying machines is established in advance, in order to protect the pipeline from creating additional tensions in the pipes.

After the pipeline is laid in the trench, and after its cleaning and the hydrotest, then follows:

20. Final backfill of the trench (signal tape is placed durrind this operation);

21. Compacting of the soil layer;

22. Reinstatement and spreading of the stripped humus- top soil layer;

23. Plowing of the construction strip;

24. Spreading fertilizers and laying grass with grass mixtures on the construction strip in pastures, meadows and forest areas;

25. Conducting anti-erosion measures – draining ditches, anti-erosion green fences with suitable grass and bushes;

26. Transporting the remaining earth mass away from the construction strip to landfills set for the purpose;

27. Placing signalling signs for marking the gas pipeline route at 2.5 m on the right of its axis in the direction of movement of the gas flow.

The technologies developed for shaping up the slopes, the terraces and the trench of the gas pipeline will comply with the engineering-gelogical, geological and hydro-geological conditions along the gas pipeline route, the presence of items and facilities subject to blasting-seismic protection, the linearity and the available drilling and loading technique.

The passage through natural or artificial barriers and facilities is executed in the according to the respective technological instructions for the trenchless method. The crossing of the pipeline through roads, railway lines, or other engineering equipment is executed by placing it in a protective mantle, laid in advance by the trenchless method (Figure 1.2.1.2-1).

Figure 1.2.1.2-1 Cross section of a trench

Cleaning the interior of the gas pipeline

The cleaning of the interior of the gas pipeline from soil, water or some construction debris that have eventually entered can be performed by one of the two methods (or both sequently):

Washing out with water,

Blowing through with air and passing of special pistons (cleaning pigs- preferred method)

After completing the cleaning, in both ends of the cleaned sector are mounted temporary closing caps. When the cleaning is done by blowing through with air, the length of the sector cannot be greater than the length between two block valves. The washing out of the gas pipeline with water is done in sectors, and the water is transferred via orifices from one sector to the other. The filling of the sector with water and its throwing out is done at locations prepared in advance.

Hydraulic test

The hydraulic test is performed in compliance with a prepared in advance technological instruction on a ready backfilled sector of the pipeline, with water being transferred via orifices from one sector to the other. The proper safety measures are taken during the test, in order to avert eventual risks to the personnel and the environment. While the water pressure in the tested sector is being increased, no unauthorized person is allowed to enter the test zone – beside fences, there are warning signs forbidding the entry on that zone. The discharge of the water from the hydrotest is done into a chosen in advance water body, coordinated with the respective authorities. The water sources (rivers or other) for water abstraction as well as the water recipients of the discharged hydrotest water will be determined and assessed accordingly in the ESIA report. If necessary the hydrotest water will be treated prior to discharging depending on the specifics of the water recipient and according to the legislation in force and the authority requirements if any.

After the successful execution of the hydrotest and the emptying of the pipeline of the water, the sectors are dried by blowing through with dry and oil-free air and special pistons. The blowing through continues till the air coming out of the gas pipeline reaches the dew point1

minus 20°С at pressure of 1 bar. The dried sector is hermetically closed till its handing over for operation.

Blasting works

Blasting works are to be performed in all sectors where rocks are identified as had to very hard. The data of the latter have to be confirmed after the completion of the envisioned drilling works, which are in greater density in the rocky areas. It is possible to have a significant reduction of the uses of this method, if the drilled boreholes prove that the rocks are strongly weathered.

1.2.1.3. Construction camps and sites

The gas pipeline route is planned to be divided in 50 km sectors with the purpose of optimizing the construction-mounting works (CMW) In each sector 2 storage sites will be set up (at 25 km distance) and one temporary camp (Figure 1.2.1.3-1).

Storage sites

They are intended for storing pipes of different sizes and fittings, and their minimum area is 0.5 ha. They will be located near motor roads or railways. They will have a 2 m tall fence, and will be equipped with loading/unloading facilities.

Temporary camps

They are constructed for setting up vans (Figure 1.2.1.3-1), with changing rooms and worker canteens, office for the management of the sector, cabinet for hand-held firefighting tools, first aid room with the necessary sanitary dressing materials and a litter, containers for instruments, containers for construction and household waste, bathrooms and WC, storage areas for construction materials, label with the signs and signals used at the construction site. The minimum area is 0.3 ha.

The location of the sites along the route and the final areas will be presented at the stage of Final CDP (Comprehensive Development Plan) – approval, depending on the rented terrains and an expert identification of an average staff number for executing the construction.

The final size of the sites depends on the choice of Contractor and his forecasts as regards the organization for the execution of the construction works, according to the envisaged term for completing the gas pipeline sector, and coordinated with the Employer.

1 When the air is cooled, the “extra” moisture is separated from it by condensing, and the temperature at which the relative humidity reaches 100% and condensing occurs is called “dew point”

1.2.1.8. Testing and commissioning

Pressure testing - hydrotest

According to the Ordinance for the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and apparatuses for natural gas and BSS EN 12327 “Systems for gas supply. Pressure testing and procedure for commissioning. Functional requirements” the pressure testing procedures are carried out by an authorized person and according to approved technological instruction.

The testing of the gas pipelines, of the facilities and installations for natural gas is performed acc. to BDS EN 12327 and following the construction – technology instruction after completing the mounting and the preliminary cleaning of the inner surface of the linear elements of the network for the separate sectors.

The instruction is provided by the constructor and is approved by the head of the comisioners, taking into account the local conditions, the national legislation, standards and/or practical rules for determining the:

Method of testing; The testing pressure; Period of the tests; Testing environment; Criteria for approval; Admissible pressure; Minimum pressure in the existing system for gas supply; Methods for detecting defects; Releasing of the testing environment; Removal of the water.

Before the tests, the inside of the pipeline will be cleaned from production scale and also of soil, water and other articles which by chance might have entered the pipeline.

The cleaning of the pipeline is done after it is laid in the trench and the trench is backfilled. When cleaning the pipeline it is not permitted to allow cleaning components and various pollutants to enter the linear fittings. After cleaning the interior of the gas pipeline by blowing or washing, on the edges of purified section are mounted temporary inventory bottoms (caps).

The hydrotests are to be performed when the earth and water temperatures are at least +2С. The tests will be carried by sections limited by linear reinforcement or caps. The pressure test is not performed with closed valves.

After carrying out the hydraulic test the water will be led to a suitable water recipient. All drainage lines will be properly fortified, in order to prevent movement when the water is being let out. The discharge into a running water body will be performed in accord with obtained approvals.

The discharge of the water in a water body will be with such location as not to cause erosion of the bank, washing out and residual sedimentation.

In case of difficulties in the inserting and eventually removing the water from the pipeline system, the ends of the pipeline system are connected with suitable PIG launchers/receivers installations.

The method/procedure of removing the water will be presented in written form.

The final drying of the gas pipeline is done by passing foam pistons with high density, propelled by compressed air through the section to be dried. The used compressed air must be degreased and dry, reaching the dew point of –20С at pressure of 1 bar.

When the necessary drying level is reached, the sector is packed and closed, filled with dry air with minimum 1 bar pressure, and maintained till its commissioning.

Pinpointing sources (rivers, water bodies) where the water is withdrawn and rivers or water bodies where the water is discharged would be made in hydrological research and in the EIA report would be described.

1.2.1.8.1. Resources used

The hydrotest will require:

Type Quantity, m3 Note

Water 615 000

The quoted amount is the volume of the pipe for the whole Bulgarian sector. When carrying out hydraulic tests, the gas pipeline will be divided in sections, and, if possible, a certain amount of water will be reused by transferring to the next section for its hydraulic test.

1.2.2.1.1. Gas pipeline

The transported natural gas will be held in one closed system (pipeline) under high pressure without any contact with the environment.

1.2.2.1.2. Facilities related to the gas pipeline

Gas Metering Stations (GMS)

The main gas metering station of the gas flow passing the territory of Republic of Bulgaria will be located on the land of Oryahovo municipality at km 405. A similar station with smaller capacity will be located on the site of the inter-system connection Off-Take (OT), situated close to the existing CS Lozentes

Off-take Stations (OS)

Only one off-take station will be built at present Stage, near the existing CS Lozenets, a block valve station with a GMS.

Gas pipeline Pigging stations (PS).

The project envisages the construction of two pigging stations during this stage.

Block valve stations (BVS)

Along the gas pipeline route are envisioned sectioning block valve stations (at maximum distance of 30 km from one another), equipped with devices for automatic closure in case of emergency.

Blow-off pipes for natural gas release

These are components of the above ground site sub-items, serving for controlled release of natural gas, in case of need, as well as to lead away the launched natural gas from the safety valves.

1.2.2.2. Capacity

After the realization of the investment proposal on present Stage, the capacity of the gas pipeline will reach 8.5 billion m3 of natural gas per year (could be increased if required up to 31 billion m3 by a hydraulic improvement – additional CS-future stages).

1.2.2.3. Type and amount of the resources

During the operation only electric power and water are used.

Water

The necessary amount of water in the site sub-items (GMS and ISC) will be provided by the settlement water supply network of the respective municipalities based on a contract signed with the Water Supply and Sewerage Ltd. Below there is data on the forecast water consumption

Due to the significant amount of excess spoils and the maximum length of the pipeline, the project provides different ways of their treatment:

• Disposal in landfills for construction waste, located near a section of pipeline;

• Use of excess earth mass for:

Fill other excavations near the pipeline;

Soil capping of landfills;

Building dikes;

Strengthen banks and others similar activities

All treatment activities of excess spoil will be coordinated with the municipal administrations. Prepare a plan for waste management and especially the excess spoil, depending on specific conditions and techno-economic environment.

Water pollution

1.3.2.1. During construction

Surface water

For short time during construction it can be expected to have an increase in the river water turbidity due to the crossing of the rivers via the open cut method. If the river sediments in the points of crossing are contaminated with harmful substances, the water will be polluted secondarily (as sequence) for a short period of time. When the river water passes onwards to the next sectors, the process subsides, as well also as result of suspended matter sedimentation.

The household-sewage waste water will be collected in chemical toilets or excavated pits, which will be cleaned regularly with specialized trucks of licensed companies for those purpose.

Groundwater

No pollution of the groundwater is expected during construction when observing the regulations and the technological requirements. Such pollution can be caused only by accidental spills of fuel and lubricants from construction machinery within the range of the construction activities at the sites or indirectly when polluted surface and rain water reaches the groundwater.

1.3.2.2. During operation

Surface water

During operation the waste water will be mainly household-sewage water, for which local facilities will be provided (chemical toilets or excavated pits). The cleaning will be done by licensed companies as per signed contract.

Groundwater

No pollution of the groundwater is expected during operation of the gas pipeline.

1.3.3. Air pollution

1.3.3.1. During construction

During the construction period, an increase of the emissions of certain noxious atmospheric pollutants, particulate matter (PM) and other pollutants, caused by a large number of emissions-generating operations and processes, is expected:

Exhaust gases from the internal combustion engines of the equipment used in the construction works;

Material handling operations, such as bulldozing, scraping and removal of particulate matters;

Wind erosion from open storage piles or operational areas.

Internal combustion engines emissions

Evaluation of the impact on air during the construction phase will be done on information given on the numbers, categories and power output of the construction equipment, as well as their working days and hours in the year.

Estimates of the gaseous emissions from construction machinery will be based on the methodology of EMEP/CORINAIR Atmospheric Emission Inventory Guidebook, 2009, Chapter 1.A.4 Other Mobile, SNAP code 0808.

The emission levels of exhaust gases for one day of 8 hours work of appropriate to construction phase diesel machinery (1 excavator-60kW, 1 caterpillar excavator with a mechanic shovel (60 kW), 1 heavy truck for transportation of suppliers and etc. (300 kW) and 1 mobile crane (240 kW) are given in Table 1.3.3.1-1.

Table 1.3.3.1-1Emission levels from construction equipment

Construction techniques 4 292.02 0.26 1.85 76.03 0.13 17.68 7.74 3.09 0.01

The above emission quantities will be released directly in the air from the exhausts of machines with internal combustion engines.

Dust emissions

Dust emissions calculations are based on the following activities:

1. Clearing, bulldozing, scraping, grading, and other earth excavation works;

2. Dust material handling (loading and unloading) operations of earth masses;

3. Dust entertainment from heavy construction machines traffic on temporary unpaved roads;

4. Wind erosion from an open dust storage operational areas (depots for earth masses).

Emission estimates for the above operations are based on the emission factors of the American Environmental Protection Agency (EPA) for working in open dusty areas: Construction and Aggregate Processing and Fugitive Dust Open Sources - US EPA, Emission factors AP-421.

The emission levels are mitigated by the natural process of precipitation, or if the construction areas are spying during dry conditions.

In general, the construction period is limited and the additional emissions will have no significant impact on the air quality. In order to avoid the risk of pollution one has to keep exact schedule of the construction works, conforming with the meteorological conditions, i.e. to allow the natural capacity of the atmosphere to self purify. However, during calm conditions and the air is much polluted, it is recommended to temporarily stop the construction works and let disperse the pollution.

1 http://www.epa.gov/ttn/chief/ap42/index.html

1.3.3.2. During operation

In general, fugitive emissions from the project may be attributed to the Pipeline System on the whole, including all associated surface facilities.

While methane (CH4) is the predominant type of greenhouse gas emitted as a fugitive emission in the gas sector, emissions of carbon dioxide (CO2) to a much lesser extent may also occur. CO2 is present as a natural constituent of all focill hydrocarbon streams – see gas composition on Table 1.1.1.3-1.

Natural gas pipeline transportation

The IPCC document Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories is used to calculate methane (CH4) and carbon dioxide (CO2) emissions from pipeline gas transport (Table 1.3.3-3) per 412 km of transmission over Bulgarian territory1. The global warming amount of greenhouse gas (tCO2eq) is calculated, too.

Table 1.3.3-3

Amounts of emissions from natural gas transport.

pollutant CH4 CO2

CO2-eq.Emission factorGg per km of transmission pipeline

3.4E-03 1.3E-05

km tons per year412 1 400.8 5.4 29 4222.2

For completeness of the inventory, indicative border reference values (benchmarks) were developed for the methane losses per year. The reference values for lowest and highest emission (loss) of methane in the transport of gas along main (trunk) gas pipeline are respectively between 50 and 5 000 tons per year for the Nabucco route of 412 km on Bulgarian territory. As shown in the above table, the methane emissions are in the range of these values.

Emissions from maintenance activities

There are no potential emission sources on the territory of Bulgaria at initial stage.

The design of the facility requires planning measures for not allowing unorganized emissions from the maintenance stations.

1.3.4. Soil contamination

1.3.4.1. During construction

It is possible to have insignificant soil contamination from atmospheric precipitation, generated by the described above air pollution during construction. It is possible also to have insignificant contamination with oil products in the work processes of building the gas transporting system and its facilities, using construction, transport and mounting machines, with eventual accidents related to the machines during construction. A potential, but removable pollutant of the soil is the construction and households waste generated in the process of construction of the pipeline.

1  When take place activities on pipe cleaning, for example, there is leakage of gas, even if the pipe system is encapsulated.

1.3.4.2. During operation

No additional pollutions, similar to those described for the construction phase, are expected, except for accidents occurred during operation and the actions in response to these accidents.

1.3.5. Harmful physical factors

1.3.5.1. During construction

Noise

A source of noise emissions in the environment will be the used construction and mounting equipment for executing the various works – excavation, backfilling/landfilling, mounting, welding, concrete, transport, etc. The main units of machines and equipment are: excavator, bulldozer, motor crane, front loader, trenchless drilling probe, horizontal directional drilling equipment (when crossing roads, railways, rivers), trucks, etc. The levels of noise emitted by them are within 80-105 dBA. The EIA report will provide specific noise level values for the separate machines used: an assessment will be given of the expected equivalent noise level on the construction site during operation of the respective piece of equipment.

The sites used as temporary storage of pipeline components (pipes, etc.), necessary construction and other materials, as well as the transport of these components to the storage sites and from there to the construction strip will also be considered as sources of noise. As a source of noise will be considered also the eventual detonations made during crossing sections of the pipeline route with hard rocks

The EIA report will define and evaluate the expected equivalent noise level reaching areas with regulated noise regime (settlements) close to the construction strip. The assessment will be made according to the requirements of the Bulgarian law. If other source(s) is/are present along the pipeline route, beside the effect of the construction works an estimation will be made of the cumulative effect of the action of all noise sources located near areas of impact1.

Vibrations

The main sources of vibration are:

Vibrations caused by breaking hard (rocky) sections with pneumatic hammers, rippling and blasting works;

Vibrations caused by moving transport vehicles and construction machinery – tugs, pipe carriers, tip Lorries, excavators, cranes etc.

Vibrations caused by the moving parts of compressors, machines and big engines.

From the above vibration sources should be distinguished the blasting works, the most significant (microseismic), but short-lived source of oscillations. The other sources are with limited (pneumatic hammers) to negligible impact (construction compressors).

Physical factors

1. Illumination

The most significant sources are the electric arc in welding works and gas flame in gas flame cutting.

1 The first stage of the gas pipeline construction does not envision setting up compressor stations on the territory of Bulgaria, therefore they will not be considered in the PEIA as potential source of nouse. Beside the gas pipe the system will include the the following ground facilities: stop valves, gas measuring stations, cleaning stations, inter-system connections, etc..

The welding is mainly automatic (GMAW) in a protective gas media, and because of the technology the process is limited to chambers (tents) and is performed by qualified operators, who are not in the immediate vicinity during the welding itself.

The welding in the open (mainly SMAW- shielded metal arc welding – manual metal arc) is done by qualified and certified arc welders, duly equipped with individual protective means (masks, gloves, overalls).

Lighting of construction camps and storage sites will be conventional and it is not considered like harmful radiation. Its impact on the environment will be minimal and will be evaluated in ESIA.

2. Heat radiation

It occurs in:

Electrical induction heating, which takes place in the weld area before welding. The temperature of the heated area reaches around and above 150°C;

When welding at over 3100°C in the area of arc welding, the heat is dissipated by the welding components and air convection.

For individual protection one should wear suitable clothing, masks, gloves (see illumination-welding)

3. Electromagnetic radiation

Gamma rays are emitted in one of the methods for control of the welding joints and the insulation – X-ray defectoscopy. With this method the survey are performed in strips of 20 cm around the weld (20 discrete images / gamma lightings / per seam, with about 55÷90 seams per kilometer of pipeline). The non-destructive testing (NDT) of the welding seams along the pipeline is executed by a control body accredited by the Executive Agency - “ Bulgarian Acreditation Office”

4. Sound waves

Ultrasonic waves are transmitted when using ultrasonic defectoscopy, which is the preferred survey method (for practices see API 1104 ; DNV-OS-F101; ASTM E 1961 ; ASTM E 164)

The impact of the adverse radiation on the environment is negligible. Their impact is mainly on the working environment. Therefore, for now only personal protection means are indicated primarily. In ESIA report will be assessed in detail the expected impacts.

1.3.5.2. During operation

In the present stage of the project, in normal operation, the gas transporting system is not expected to be a source of noise and harmful physical radiations in the environment.

Environmental impact of conventional lighting from above ground installations (Block Valve Station, Pigging Stations, Gas Metering Stations, etc.) will be minimal and will be assessed in the EIA.

2. 2. ALTERNATIVES FOR IMPLEMENTING THE INVESTMENT PROPOSAL

On the territory of Bulgaria there is a network of transit and national gas pipelines, built mainly in the period 1970 ÷ 1990. The selected general direction of the gas pipeline route from southeast (the border with Turkey) to northwest (near the town of Oryahovo, at the border with Romania) crosses diagonally the territory of Bulgaria and some of the existing gas pipelines.

The main aim in selecting a route for the proposed gas pipeline is to use to a maximum extent the routes of the existing gas pipelines. In this context, the pipeline route can be divided in two basic types:

Type 1 – along existing gas pipelines;

Type 2 – in a standalone route.

In the sectors beside the existing gas pipelines only one optimal version is developed. These sectors are from km 0+000 to km 76+600 – beside the existing transit gas pipelines to Turkey, and from km 223+195 to km 325+400 – beside the existing National gas pipeline. In these sectors the gas pipeline passes at a minimum distance from the existing gas pipelines, and in separate locations with 1-2 km length it passes at a greater distance for bypassing Natura 2000 protected areas, or overcoming topographic obstacles.

There are two versions developed for the sectors of the standalone route – in the crossing of the Balkan mountain from km 76+600 to km 223+195 and in the crossing of the existing National gas pipeline in northern direction towards the Danube from km 325+400 to km 397+960.

2.1. Null alternative (existing situation)

“Null alternative” is connected with the decision not to perform the project. There are no legal prerequisites or reasons relating to environmental hazards and human health that would lead to "Null alternative".

The engineering design for the Construction of NABUCCO transit gas pipeline on the territory of Bulgaria corresponds to the best practice in the industry.

The construction solutions chosen by the design team for building the route are the optimal ones from the viewpoint of the already existing infrastructure, the Natura 2000 protected zones, as well as the crossing of rivers and infrastructure items.

The adoption of a “Null alternative” would mean not to execute an international investment project of high priority for the European community.

2.2. Location alternatives and technological peculiarities of the investment proposal

2.2.1. Location alternatives

Two main location alternatives have been developed for the realization of the investment proposal (Figure 2.2.1-1):

- Track following a survey, conducted in 2004, called TFS – parallel to the existing gas pipeline;

page 60 of 156

- 2 alternative routes – at the beginning (crossing the Balkan mountain) and the end of the route (branching of the gas pipeline from the route of the existing National gas pipeline).

2.2.1.1. A – crossing of the Balkan mountain

2.2.1.1.1. Option 1A (east) - from km 76+600 to km 223+195 – length 146.595 km

The direction of the corridor is to the northwest, crossing the districts of Burgas, Shumen and Targovishte.

From km 76+600 to km 103+000 the terrain is hilly, with altitude 450÷200 m. The end of the sector touches the line of the south outskirts of the Balkan mountain, from where it starts to rise.

From km 103+000 to km 121+000 the gas pipeline crosses the Balkan mountain. This is the most difficult for construction sector, and 4 options for a suitable route have been discussed for it. Most important for the choice proved to be the topography of the sector, the detours and minimum crossings of Natura 2000 zones and the optimal length.

In this sector the route ascends to the highest point on Bulgarian territory – Alaborun peak with elevation 769.70 at km 111+000. After several steep descents and ascents, the Balkan mountain is crossed at km 120+844.

After crossing the Balkan mountain till km 192+500 the gas pipeline continues its northwest direction, the terrain is hilly, with small convex and concave terrain forms, intersected by many gullies with seasonal water discharge. After km 192+500, the gas pipeline shares a common route with the existing National gas pipeline. After this point the route takes a west direction, and keeps the direction till km 223+195, where this option ends.

The option crosses four greater rivers: Luda Kamchia River at km 102+815, Topoklidere at km 121+575, Golyama Kamchia River at km 132+740, Popovska River at km 188+630 and about 30 smaller streams and gullies.

Around 11.5 km of the route length passes through protected zone BG 0002029 Kotlenska Mountain classified as such by the Directive for wild bird protection (79/409/EEC). This is the main advantage of this option – shorter crossing of a Natura 2000 area in order to preserve the biological diversity.

Crossings of above ground facilities

The route crosses four main roads – at km 124+185, km 153+568, km 188+875, km 209+680, and 19 secondary roads. The route crosses the electrified double railway line Sofia-Varna at km 183+500.

Crossings of underground facilities

At this stage no crossings of underground communications have been studied.

Passage

The route crosses roads with permanent pavement every 5÷7 km, which provide access to it. Difficulties in the future building of the pipeline in view of the approach are expected only in the area of the Balkan mountain, in a sector with length of about 20 km. The area is hard to access, the nearest road to the north is at km 124+000, and on the south – at km 103+000. These roads have a stone pavement and in some sectors need improvement.

page 61 of 156

2.2.1.1.2. Option 2A (west) – from km 76+600 to km 206+788 –the length is 130.188 km

The direction of the route is to the northwest, crossing the districts of Burgas, Sliven and Veliko Tarnovo. From km 80+000 to km 103+000 the route passes through a hilly terrain with altitude from 200 to 500 m, gradually ascending the southern slopes of the Balkan mountain.

In this sector it crosses the first bigger river on Bulgarian territory – Luda Kamchia River, about 50 m wide and with a flooded terrace at high water – 150 m wide.

From km 103+000 to km 148+000 the pipeline route crosses the East Balkan mountain through one of its parts – Kotlenska Mountain. There are no settlements in this part of the mountain, the mountain slopes are densely forested and access to the route is very difficult. There are no motor roads, and forest (dirt) roads are rare, most of them used in the past for lumber transport.

From km 148+000 to km 206+000 the route passes through a hilly terrain with altitude from 200 to 400 m, gradually descending the northern slopes of the Balkan mountain.

This option of the route crosses three bigger rivers: Mochuritsa River at km 89+255, Luda Kamchia River km 97+200, Kara Dere River at km 162+120 and about 40 smaller rivers and gullies.

According data obtained from MOEW at km 115-116 the pipeline route corridor passes at distance 10-30 m the deposit Lahama (with granted concession) and deposit Trite Vyatara (with probably expected concession procedure).

About 54 km of the route’s length passes through Natura 2000 protected areas – BG 0000196 Mochuritsa River, BG 0000139 Luda Kamchia River, BG 0000136 Upper Luda Kamchia River, BG 0000117 Kotlenska Mountain – Directive 92/43/EEC of 21 May 1992 on conservation of natural habitats and wild flora and fauna, and BG 0002029 Kotlenska Mountain - Directive of the Council dated 02.04.1979 on wild birds protection (79/409/EEC).

Crossings of above ground facilities

The route crosses one 1st class main road at km 168+850 19 secondary roads. At km 184+260 the route crosses the Sofia-Varna electrified double railway line.

Crossings of underground facilities

At this stage there is no data regarding the crossing of underground communications.

Passage

The route passes mainly dirt roads, private farm land – fields and pastures, with frequent change of the slopes, ascending and descending multiple gullies with no water for the greater part of the year. The route crosses roads with permanent pavement every 5÷7 km, and these roads provide the access to it. An exception is the crossing of the Balkan mountain, where access to the route is very difficult.

A comparison of the routes is presented in Table 2.2.1.1-1 as per the above criteria, the advantages are marked with (+), the disadvantages – with (-) and the equivalence – with (0).

2.2.1.2. B – deviation of the gas pipeline from the route of the existing National gas pipeline

2.2.1.2.1. Option 1B (east) - from km 325+400 to km 397+960 – length 72.560 km

This is the sector of the gas pipeline, which deviates from the common corridor with the National gas pipeline (west of the village of Nikolaevo) and passes further in northwest direction to the Danube River and the border with Romania. The gas pipeline passes mainly along the option selected in the survey of 2004 (Figure. 2.2.1-1).

The direction of the route is to the northwest, crossing in succession district Pleven through the municipalities Pleven, Dolni Dabnik, Iskar, Dolna Mitropolia, and district Vratsa through the municipality of Oryahovo. The number of crossed community lands is 14.

The route in this sector passes through an even terrain (plain) with altitude from 150 to 300 m.

The option crosses 3 big rivers: Vit River at km 341+200, Iskar River at km 372+250, Gostilya River at km 377+190. From km 341+500 to km 364+000 the route passes through irrigated fields with many irrigation canals (lined and earth), 12 of them with a width of 5÷30 m and two with a width up to 5 m.

page 63 of 156

About 3 km of the route’s length crosses Natura 2000 protected areas, 1.4 km of which – through an area as per the Directive of the Council on wild birds protection, dated 02.04.1979 (79/409/EEC) – BG 0000240 Studenets, and 1.6 km through areas as per the Directive 92/43/EEC on the conservation of natural habitats and wild flora and fauna - BG 0000240 Studenets, BG 0000181 Vit River and BG 0000613 Iskar River.

In this sector the gas pipeline crosses 2 main roads and 8 secondary roads. At km 352+205 the route crosses the Sofia-Varna electrified double railway line.

Crossings of underground facilities

At this stage no crossings of underground communications have been studied.

Passage

For the whole of its length the gas pipeline passes in a standalone route, beside dirt roads. The sector is easily approached. No additional access roads are envisaged. The connection of the construction strip to the existing road network will be in the crossing locations – every 5 – 6 km on the average.

2.2.1.2.2. Option 2B (west) - from km 309+000 to km 398+775 – length 89.775 km

This option was developed with the present survey, as an alternative to the survey made in 2004 г. (TFS).

Its length is 89.775 km, from km 309+000 to km 333+300 the direction of the route is to the west, passing parallel and close to the existing National gas pipeline – the northern ring. After km 333+300 the route’s direction is to the northwest, keeping in this direction till km 398+775, where this option ends. Along its length this option of the route crosses the districts Pleven, Lovech and Vratsa.

The option crosses two bigger rivers: Vit River at km 332+200, Iskar River at km 358+130 and about 20 smaller streams and gullies.

For about 18.8 km of its length the route crosses Natura 2000 areas, 17.6 km of which are under the Directive for protection of wild birds (79/409/EEC) - BG 0000240 Studenets, BG 0002095 Gorni Dabnik Telish, and 1.2 km – as per Directive 92/43/EEC OF 21.05 1992 on the conservation of natural habitats and wild flora and fauna - BG 0000240 Studenets and BG 0000613 Iskar River.

Crossings of above ground facilities

The route crosses one main road at km 347+000, and 13 secondary roads, and an electrified double railway line at km 349+000.

Crossings of underground facilities

At this stage no crossings of underground communications have been studied.

2.2.2. Alternatives per technological peculiarities of the construction

No alternatives per technological peculiarities were considered, as when building the NABUCCO gas pipeline through 5 states it is mandatory to implement European and international standards and methods. In ESIA report different methods for crossing of rovers, roads and other infrastructures will be discussed as alternatives and part of the approved technology for building the project.

3. 3. CHARACTERISTICS OF THE ENVIRONMENT, IN WHICH THE INVESTMENT PROPOSAL IS TO BE REALIZED, AN IMPACT FORECAST

In paragraph 3 for each component are described available sources of data to be done assess of its current state as an object of the impact of the investment proposal –gas pipeline Nabucco (Climatic Reference book, publications of the Bulgarian Academy of Sciences, Ministry of Environment and Basin Directorates Bulletins and specialized literature, information from official sources available in Internet, etc.

Furthermore, in developing the EIA report, actual data from special conducted observations and research will be used:

• Hydrological and hydro-geomorphologic characteristics of rivers in areas of passing the pipeline;

• Physicochemical parameters of the geological basement resulting from the engineering and geological survey;

• Active faults and seismic risk evaluation;

• Characteristics of the land in result of engineering and geological survey;

• Characteristics of groundwater, the level and nature of groundwater obtained from the engineering-geological survey;

While conducting field observations, data on sensitive areas, availability of water sources for drinking water, the state of flora, fauna and protected areas, and other components on the route of the pipeline will be collected.

3.1. Ambient air and climate

3.1.1. Climate

The route of the Nabucco pipeline (from village Strandja to Oryahovo) falls in different geographic regions of Bulgaria, characterized by different topography and climate, namely:

Region-1  –  Strandzha–Sungurlare  covers a flat and hilly relief with altitude between 100 and 400m. This includes parts of the eastern slopes of Strandzha Mountain, plains and hilly areas of eastern Thrace and low-mountain and hilly areas of the East Balkan mountain. According to the climatic classification of Bulgaria this region has a Continental-Mediterranean (CM) climate. The average air temperature in the region is about 12.7C with maximum in July (about 23-24C) and minimum in January - about 2-2.5C. The monthly mean air temperature amplitude varies between 8С and 15С with minimum in January and maximum in summer, with mean annual value of 11.7С.

Region-2  –  Sungurlare–Popovo  covers a low-mountain hilly and low-valley relief with altitude between 200 and 700 m. The gas pipeline route crosses parts of the East Balkan mountain and East Fore-Balkan with Transitional Continental (TC) climate. The annual mean temperature in the region is about 12.2С with maximum in July - about 23С, and minimum in January – about 2С. The monthly mean air temperature amplitude varies between 7С and 13С with annual mean value of 9.8С

Region-3  –  Popovo (Strazhitsa)–Oryahovo  covers a flat and hilly relief with altitude from 50 m to 300 m, passing through Middle and Western Danube Plain with Moderate Continental (MC) climate. In the highest part of the Nabucco route (the area near Kotel, East Balkan mountain) the annual mean temperature is about 10.5-11.0С with maximum in July - 21С and minimum in January – about 0С. In the region of East Fore Balkan

page 67 of 156

(Kotel-Popovo) the annual mean temperature is the same - 10.5-11.0С. In the region of the Danube Plain (Popovo-V.Tarnovo-Pleven-Lom) the annual mean air temperature if from 11.5 to 12.2С, with maximum in July (around and above 23С) and minimum in January – about 0С. The monthly mean temperature amplitude varies between 6.5С and 13.5С, and in the area of the town of Mizia reaches up to 15С, with annual mean value of 10.2С

The annual amount of precipitation for the entire outside-the-mountain pipeline route part is between 550 and 650 mm. Only in the East Balkan mountain part (with altitude of 600-700 m) the precipitation is up to 700 mm. In CM climate region the maximum is in the autumn-winter period, while in MC climate region – in the spring-summer period. The minimum amounts of precipitation are in the summer-autumn period in south Bulgaria, and in the winter season - in north Bulgaria.

Typical of the snow cover along the pipeline route is it’s repeating several times formation during the four cold months – from the middle of November up to middle of March. The total number of days with snow cover in the CM and TC climate regions is between 10 and 20 annually, while in the MC climate region – about 40 days. In parts of the East Balkan mountain the number of days with snow cover is 50

The monthly mean and annual mean wind speed in the outside-the-mountain pipeline route part is from 2 to 2.5 m/s with maximum in spring (March-May) and minimum – in summer and autumn. Only in the East Balkan mountain part the mean wind velocity is bigger, reaching 3.5 m/s in same inter-annual course. The predominant wind direction is west-northwest, followed by northeast. In parts of the East Balkan mountain and Fore-Balkan there is enhanced frequency of south winds (Fig. 3.1-1).

Figure 3.1-1 Wind roses over the Bulgarian Nabucco pipeline route.

The Continental-Mediterranean climate according to the Köppen classification is Cfа – moderate warm climate with hot summer, and according Thornthwaite the climate is warm, semiarid.

The Transitional-Continental climate region according Köppen is Cfа, too. According Thornthwaite the climate is dry, sub-humid (dry with insufficient moisture).

page 68 of 156

The Moderate-Continental climate according Köppen is Cfb type – moderately warm moist climate with warm summer. According Thornthwaite the climate is moderately warm, dry-subhumid, i.e. he makes no difference between Transitional-Continental and Moderate-Continental climate.

No negative impact on the climate is expected during the construction or operation of the Nabucco gas pipeline.

3.1.2. Quality of the ambient air

Along the Bulgarian part of the Nabucco gas pipeline route there are only 2 areas for ambient air quality assessment and management (AAAQAM), specified by the Minister of Environment and Waters, according Directive 96/62/EC, where it is mandatory to control emissions and concentrations in the air - Gorna Oryahovitsa and Pleven.

The assessment on air quality in these areas is prepared based on data from Annual Reports on the Status and Protection of the Environment (emissions and measured concentrations for a period of four years (2003 ÷ 2006). The comparison shows that the levels of sulphur and nitrogen oxides are greater for Pleven, where the industry is better developed than in Gorna Oryahovitsa.

Basically, the Nabucco gas pipeline route passes mainly through open countryside areas far from major urban or industrial areas. Therefore, the levels of contamination with basic or specific pollutants: sulphur and nitrogen oxides, methane, non-methane volatile organic compounds, ammonia, etc. are very low.

By the implementation of the project the following impacts are anticipated

During construction

From the construction activities dust and harmful gases emissions are to be expected, in result of the operations of earth masses, the motor vehicles movements and the engines of the construction and supporting technique.

The expected impacts will be limited in the construction area, will be temporary and reversible after the end of the construction works.

During operation:

No change in the quality of the ambient air is expected during the operation of Nabucco gas pipeline.

In emergency situations:

In the operation stations will be installed blow-through pipes for reaction in case of emergency situations. The average volume of the gas released into the atmosphere when blowing-through one chamber is about 5000 Nm3 for the time of the blow-through procedure.

In case of emergency situations, the harmful substances emissions during construction, as well during operational phase will be generated in case of fire accident (intentional or unintentional). The quantity of emission will depend of the size of the accident, i.e. from its duration and from the amount of substance involved in the accident. On risk will be exposed the personnel involved in the respective emergency operations only.

3.2. Water

3.2.1. Surface water

page 69 of 156

The hydrologic conditions have been surveyed on the basis of available information and literature. A general characteristic is presented about the hydrological peculiarities of the areas crossed by the gas pipeline route. It passes through physical-geographic regions (Geography of Bulgaria, 2002) with their own specific climate, character of precipitation, relief and runoff/discharge features.

The precipitation is distributed irregularly, both along the gas pipeline route and throughout the year. It also varies a lot for the different years, which leads to insufficient or excessive moisture.

Seasonal and annual mean precipitation

Figure 3.2-1 Precipitation measured in the stations located from south to north.

The peculiarities in the distribution of precipitation are narrowly connected with air circulation over Bulgaria, which in separate areas is significantly influenced by the orographic peculiarities.

Data from 32 stations, located nearest to the pipeline route, was used for characterizing the precipitation regime. These stations are located irregularly depending on the hydrologic conditions in the specific areas. The observations on precipitation have been performed for many years, with many of the stations starting to operate around 1930. The number of stations and the duration of the observations provide sufficient data for characterizing the precipitation along the gas pipeline route.

The discharges of rivers, tributaries and gullies along the gas pipeline route are characterized by great irregularity both for the different years and for the different seasons in the year. The greater part of the annual discharge (65-75%) takes place in the winter and spring seasons, and the remaining part are in the drier seasons (summer and autumn). The running water quantities seriously drop in the dry seasons of the year, and the smaller streams and gullies dry up.

There are micro-dams set up on many of the smaller rivers and gullies, used mostly for irrigation of watering of livestock. According to regulations, their operation term is 50 years, and they are calculated for high water with repetition frequency 1 in 100 years. There is the possibility for the passage of higher water with low repeatability than the calculated one. Partial or complete destruction of the overflow facilities of the dams is also possible, and there is the risk of serious damage to gas pipeline facilities located in the neighborhood and/or of the very pipeline. The micro-dam walls are primarily from landfill earth mass with a height of up to 10-15 m.

page 70 of 156

There are big dams located at considerable distance from the pipeline route. They are perennial equalizers with big retention volumes, calculated for conducting high water with repetition rate 1 in 10,000 years, and will not pose any risk to the gas pipeline operation.

The main rivers (10 rivers with a width greater than 30 m), which will be crossed by the pipeline, are estimated as “water body at risk” in the meaning of the Water Framework Directive. In the sectors of crossings with the pipeline the rivers take the following categories: Ogosta River – ІІІ; Iskar River – ІІІ; Vit River – ІІ; Osam River – ІІ; Yantra River – ІІІ; Sredetska River till the first settlement – І, and till its mouth into Mandra dam – ІІ. The quality of the river water along the pipeline route depends on the location and the amount of the untreated waste water that is discharged into them, coming from the urban sewerage systems, from poorly operating local treatment facilities for technical waste water, from directly discharged technical waste water.

The rest of the water courses crossed by the corridor of the gas pipeline are: about 49 running water bodies with a width between 5 and 30 m, around 57 water courses up to 5 m wide, and about 73 seasonal ditches.

The water in the project region belongs to the territories of three basin directorates – the Black Sea, the Danube and the East Aegean basin directorates. The waste water management during construction will be considered as per the following criteria:

Methods of waste water treatment;

Sources, quantity and composition of the waste water;

Design of facilities for waste water treatment and storage;

Potential environmental impacts from waste water depending on its quantity and quality;

Possibilities for connecting to a sewerage system.

The EIA will evaluate the impact on water quality both from a hydro-chemical and from a hydro-biological viewpoint. The hydro-biological assessment will be based on the conducted field tests on the ichthyofauna, the aquatic invertebrates and the aquatic vegetation. The hydro-chemical parameters will be based on the operational monitoring of the Basin Directorates.

Microbiological samples will be additionally taken from the rivers feeding dams used for drinking water supply (the Luda Kamchia River and the Golyama Kamchia River).

The crossing of the pipeline through the rivers is planned to be performed in the period of low water. In the winter-spring season the whole river network has considerable amounts of water.

By the implementation of the project the following potential impacts are anticipated:

During construction

Depending on the selected method of crossing the rivers, the impacts will differ. The main methods of crossing are the open cut one and the horizontal directional drilling (HDD).

It is possible to cause local impacts on the environment in the period of the construction works in the crossing locations: disturbance and corrections of rivers, protective dykes on the river banks, incorrectly executed recultivation of damages, unclean riverbeds from earth masses and debris from the temporary facilities for deviation of the water from the riverbed.

On doing construction activities with appropriate technique and in respecting of all the requirements of the developed detailed emergency action plan, the possible impacts of the gas pipeline from the crossing of river watercourse will be minimal.

During operation

page 71 of 156

No significant impacts are expected in the crossing locations of the gas pipeline with the rivers during operation of the gas pipeline. Impacts can be expected in case of accidents with the pipeline, as a result of the activity of a third party, of poor maintenance of the constructed protective facilities. These impacts can be controlled with strict observance of counter-accident requirements for operation of the facilities in the respective crossing location of the riverbed with the pipeline. When the drilling works are carried out with appropriate equipment and in compliance with all requirements of a detailed emergency action plan, the possible impacts of the gas pipeline when crossing riverbeds will be minimal.

In emergency situations

Impacts are possible if there is accidents with the gas pipeline provoked by third parties or in case of inappropriate support of the built protection facilities. These impacts are controlled if all accidental requirements for facility operation at the respective site of river crossing.

The design aims at minimizing the impact of the gas pipeline on the water environment in case of accidents by taking special measures, such as the automatic closure of the block valves, which isolates the damaged pipeline section.

3.2.2. Groundwater

According to the hydro-geological division of Bulgaria, the proposed Nabucco gas pipeline crosses two of the three main regions into which the country’s territory is divided – the Intermediate and the Lower-Danube Artesian regions (Figure 3.2-2).

The intermediate region occupies the territory of Bulgaria between the ridge of the Balkan mountain and the northern slopes of the Rhodopes. It is characterized by a complex geological structure, which is the reason for the varying hydro-geological conditions. The gas pipeline route passes through 3 areas: Strandzha, Burgas and East Balkan areas.

The Lower-Danube region represents a typical artesian basin with wide area distribution of aquifers located in floors, sinking to the north. The design routes cross the so-called North Bulgarian artesian basin. It is divided in 3 subregions according to bigger structures in the Moessian Plate – Silistra, Svishtov and Lom, but most of the water bodies pass from one subregion to another.

Figure 3.2-2 Hydro-geological regional division of Bulgaria with location of the design routes () of Nabucco gas pipeline

By the implementation of the project the following impacts on groundwater are anticipated

During construction

Direct impact of the pipeline on sectors with ground water with depth up to 2 m is possible. Probably pumping out of groundwater from the trench in the low elevated sectors will be necessary, as well in the sectors of crossing alluvial water bearing sediments of river terraces. It can be expected that these waters are not contaminated and can be discharged in the water bodies. The impact is temporary, in limited area and reversible.

During operation

During normal operation no impacts on the quality and quantity of ground water is envisaged.

During emergency situations

Worsening of groundwater quality can be expected only in case of existing waterbearing layer in the location of the accident and eventual pollution due to release of contaminants during the repair works.

3.2.3. Protection zones according Art. 119a of Water Act

Sanitary-protection zones of potable water sources

Regarding the potable water sources and their sanitary-protection zones official letters with request for relevant information were sent to the following Basin Directorates: East Aegean, Black Sea and Danube River, as well to the respective regional and local water supply companies. According to the obtained until the present moment data with coordinates of the sanitary-protection zones and of the water sources, the 500 m corridor of the pipeline route crosses in 11 locations belts II and III of the sanitary-protection zones: at km 0-1, 18-19, about 26 and 28, 36-37, 56-58, 58-59, 76-78, about 189, 224-225 and225-227 (Annex 2).

At km 18, at a distance from the central line of the pipeline route corridor of 155 m, as well at km 105-106 at a distance of 180 m are located belts I of the sanitary-protection zones of water sources for potable water supply. Four water sources are located within of the 500 m corridor of the route (at km 103 and 128) or in the construction strip (at km 197-198, 289-290). For these water sources the sanitary-protection zones are still not established.

Sanitary-protection zones of potable water sources – dam lakes

The performed studies established that the pipeline route passes in vicinity of 3 dam lakes: Kamchia, Ticha and Yastrebino. All of them are included in Annex 3 of the Water Act as complex and important dam lakes. These dam lakes, including their basin and water catchment areas are public state property and are used for potable water supply, irrigation purposes and generation of hydro-electric power.

For the time being the expected Ordinance according Art. 135, item 6 of the Water Act for determination of the protection zones of water designed for potable water supply and respectively for issuing the respective orders for determination of the sanitary-protection zones is still not accepted. It is supposed that the pipeline route may cross belt III of the 3 of the mentioned dam lakes. According data obtained from the regional water supply company for Shumen region until the present moment for Ticha Dam Lake there is no determined sanitary-protection zone according the requirements of Ordinance 3/2000. Most probably for the remaining two dams there is no prepared design and established sanitary-protection zone. At the moment these issues are subject to additional checks.

Other protected water bodies

On the base of the obtained until the present moment data in vicinity of the pipeline route corridor were not identified:

- Zones for recreation and bathing in rivers and other water basins, crossed by the pipeline route;

- Zones in which the waters are sensitive to biogenic elements. Nabucco gas pipeline will not release any biogenic elements into the water bodies;

- Protected territories and Natura 2000 zones, in which the maintenance and improvement of the state of the waters is important factor for their protection. The protected territories and Natura 2000 zones are subject of assessment in the EIA report. These territories and zones are shown in Annex 2.

3.3. Land and soil

page 74 of 156

Along the Nabucco gas pipeline route it can be encountered a considerable part of the soil varieties forming the soil diversity of Bulgaria. They represent the following groups of soils (according to the taxonomic systems of Bulgaria and of FAO): Alluvial soils (FLUVISOLS, FL), Deluvial soils (COLLUVIOSOLS), Gleyic soils (GLEYSOLS, GL), Rendzinas, Rankers, (LEPTOSOLS, LP), Brown forest soils (CAMBISOLS), Smolnitsy (VERTISOLS, VR), Chernozems (CHERNOZEMS, CH), Phaeozems (PHAEOZEMS, PH), Maroon forest soils (LUVISOLS, LV), Pseudo-podzollic soils (PLANOSOLS, PL).

Among them are found soils with normally formed and with shallow profiles, with various fertility and potential as regards the main ecosystem function of the soils, with varying sensitivity to degradation processes like erosion, technogenic pollution, secondary compaction, acidification, destruction of the humus layer. The most fertile soils of 1st and 2nd category of quality are insignificantly affected (see Table 3.3-1.). Most affected (in terms of area) will be the farm land of quality category 3 and 4.

Table 3.3-1Affected land along the route of the Nabucco gas pipeline as per quality category.

Category 1 2 3 4 5 6 7 8 9 10Percent 0.005 3.0 34.4 20.0 10.0 6.4 2.5 3.8 2.8 13.4

During the implementation of the project the following impacts on soils are anticipated:

During construction

Stripping of the soil cover (humus layer) on the complete width of the construction strip and temporary stockpiling for subsequent recultivation;

Disturbance of the soil profile;

Soil compaction by the construction machines;

Soil erosion;

Disturbance of soil fertility;

Soil contamination due to eventual spills of lubricants, oil products, fuels and construction waste.

The listed negative impacts on soils will be limited only for the area of construction activities, will have temporary character and will be reversible after conducting the respective recultivation activities.

During operation

No impact on soils is expected during the operational phase.

page 75 of 156

3.4. Geological basement

In the areas along the Nabucco gas pipeline route there outcrop rocks of wide age range – from Pre-Cambrian to Quaternary.

The Undivided Pre-Cambrian is built of metamorphic rocks. It outcrops along the northwest slopes of Strandzha Mountain from the village of Strandzha to the Village of Golyamo Krushevo.

The Paleozoic consists of slightly metamorphic sedimentary rocks, diabase, metagabbroids with batches of amphibolite, granitoid, etc. They outcrop east of the village of Stefan Karadzhovo, near the village of Momina Tsarkva, east of the village of Valchi izvor, and north of the village of Oman.

Mesozoic

The Triassic is represented by the Iskar Carbonate Group, built entirely of dolomite. It outcrops south and southwest of the village of Oman.

The Middle- and Upper-Jurassic materials are represented by sedimentary rocks – clayey shale, siltstone, clayey marl, marbleized and clayey limestone, calcoshale, argillite and sandstone. They outcrop around the village of Denitsa, north of Oman, northeast of the town of Kotel, south of the village of Kraygortsi, and on the northern slopes of the Fore-Balkan.

The Lower-Cretaceous rocks are also represented by sedimentary rocks – conglomerate, sandstone, siltstone, marl and various types of limestone, divided in 7 lithostratigraphic units. They outcrop between Kotel and Popovo, around Obedinenie and around Nikolaevo.

The Upper Cretaceous is represented by Mediterranean and North European type of sediments.

The Mediterranean type of sediments are represented by terrigenous-carbonate, volcanic and volcanic-sedimentary rocks, united in lithostratigraphic units (formations). They outcrop between the villages Alexandrovo, Voinika, Parvenets, Lyulin, Nedyalsko, Palauzovo, around the village of Terziysko, as well as north of Sadovo and Medven.

The North European type of sediments consists of terrigenous-carbonate rocks with prevalence of the terrigenous component in the lower parts, and prevalence of the carbonate component – in the upper parts. These sediments are divided in 6 formations. They outcrop between the villages of Vladinya, Nikolaevo, Beglezh, Bezhanovo, Dragana and Uglen.

To the Lower Cretaceous belong also the Zhelyazkovo, Granitovo-Chernozem, Oman, Srem, Iglichina, Gorska Polyana and Ruzhitsa plutons, built of granite, grandiorite, diorite quartzdiorite, gabbro, gabbrodiorite, and gabbropyroxenite. They outcrop east of the village of Valchi izvor and west of the village of Granitets.

The Paleogene consists mostly of marine sediments, which are divided in 8 lithostratigraphic units - 4 suits and 4 formations. They have wide area distribution between the villages Mokren, Sungurlare, Sadovo and Medven in South Bulgara, and in smaller outcrops around the villages Uglen, Rakita and Barkach in North Bulgaria. The continental sediments are represented by the versicolored molassic formation built of conglomerate, sandstone, clay and coal layers. They occupy small areas west of Sadovo and north of Lozenets.

The Neogene in South Bulgaria consists of continental deposits – gravel, sand, clay and poorly cemented sandstone. They outcrop east of the village of Atolovo, and between the villages Padarevo, Chubra, Sungurlare and Grozden. In North Bulgaria it is represented by the marine sediments of the Pre-Carpathian basin, which consist of sandstone, sandy limestone, clay,

page 76 of 156

sand and gravel. Outcrops of these rocks are established around the villages Vladinya, Deventsi and Enitsa.

The Quaternary is represented by sediments various in genesis: elluvial-alluvial, eolian, proluvial and alluvial formations.

Related to the eolian formations is the loess complex, which, depending on the content of the sandy component, is divided into typical, sandy and clayey loess.

In tectonic aspect the Nabucco gas pipeline route passes through 3 structural zones – East Sredna Gora, Balkan tectonic zone and Moessian platform, which on their part consist of other tectonic units of lower order.

The following physical-geographic phenomena and processes are demonstrated along the gas pipeline route:

- The erosion processes are more strongly expressed mainly in the crossing of the Balkan mountain, where the route cuts through a more developed river-ravine network. Medium or strong areal erosion is observed in this part.

- Subsiding of the loess. The loess and the loess-like sediments are characterized by the presence of corridors, hollows and suffosion gaps, determining their considerable macro-pore nature and their subsiding properties. According to the geological hazards map of Bulgaria the gas pipeline route passes through the three types of loess materials – clayey, typical and sandy loess.

- The karst processes and phenomena are expressed in the Triassic and Upper Cretaceous carbonate sediments. A consequence of these processes is the various surface and underground karst forms.

- The landslide processes and phenomena are driven by the natural characteristics of the geological environment near the surface, and the natural and technogenic factors influencing it. Along the route there is a relatively wide distribution of marl and clayey rocks, which pose a potential risk of a development of landslide processes.

- Seismicity According to the map of seismic division of Bulgaria for a period of 1000 years, the region belongs to zones of VІІ and VІІІ degree of intensity (I) on the Medvedev-Sponheuer-Karnik scale, with seismicity coefficient (Cs) of 0.10-0.15.

In the area of the route there are established deposits of aggregate minerals and facing rock materials, as well as of oil and gas, which are registered in the National balance of reserves and resources. Of these, 12 are deposits of construction and facing rock materials (Annex 2), and 5 are deposits of oil and gas. Two of the deposits of aggregate minerals are subject of granted concessions and are located respectively at distances 1.6 and 24 km from the central line of the route. From the remaining deposits 3 deposits are located within the 500 m corridor, as one of them is crossed by the route. The deposits bare located as follows:

Deposit Km of the route Distance from the central lineKoyadzhka 65 104 mTsvetnitsa 160162 5 sectors - 40450 mGaslika 280282 Crossed by the route

During the implementation of the project the following impacts are anticipated

During construction

page 77 of 156

In the construction strip will be excavated a trench with depth of about 2,5 m. Additional excavation works will be carried out on the sites of the above ground facilities for the foundation of the respective buildings and other facilities, tanks, etc.

The listed impacts are unavoidable and irreversible.

During operation

No negative impacts on geological basement are expected at the operational stage, as well during eventual decommissioning of the pipeline.

In emergency situations

The potential impacts in a case of emergency situations will depend on the character and magnitude of the accident and the volume and character of the necessary repair works.

3.5. Biodiversity

3.5.1. Flora

On Bulgarian territory the gas pipeline route crosses four floristic regions. From south to north these are: Strandzha, Tundzha hilly plain, East Balkan mountain and Danube plain.

Typical for the region of Strandzha crossed by the route are the habitats 6210 Semi-natural dry grass and bush associations on limestone rocks (Festuco-Brometalia), (*important habitats of orchids) and 6220 *Pseudo-steppes with cereal and annual plants of class Thero-Brachypodietea.

The species building habitat 6210 in the area are: Festuca valesiaca, Cynosuros echinatus, Moenchia erecta, Trifolium striatum, Orchis mascula, Poa trivialis, Hordeum bulbosum, Orlaya grandiflora, etc. Habitat 6220 is composed of Poa pratensis, Poa bulbosa, Lagurus ovatus, Cynodon dactilon etc. Typical of the communities are annual species of genera such as Adonis, Papaver, Sillene, Nigella etc.

Edificators in the forests of this floristic region are Fagus orientalis and Quercus polycarpa in combination with Rosa canina. The low parts of the relief and the humid areas are occupied by hygrophyllic species like Glyceria fluitans, Juncus inflexus, Hordeum murinum, Mentha longifolia, Agrimonia eupatoria etc.

In the section of the route passing through the Tundzha hilly plain the grass vegetation again is represented by habitat 6220 * Pseudo-steppes with cereal and annual plants of class Thero-Brachypodietea. The forest spots in the region are edificators of the species Quercus sp. And a bush floor represented by Paliurus spina-christi and Rosa canina. Hydrophyllic vegetation is strongly developed along the valley of Mochuritsa River. It is composed of Salix аlba, Аlnus glutinosa, Butomus umbellatus, Typha sp. etc. On the territory of this floristic region the route crosses arable farm land with wheat, sunflower and vineyards.

In East Balkan mountain the grass communities crossed by the route belong to habitat 6210 Semi-natural dry grass and bush associations on limestone rocks (Festuco-Brometalia). The forest territories are represented by Habitat 9150 Thermophyllic beech forests (Cephalanthero-Fagion). Typical of the tree floor are the species Fagus sylvatica, Carpinus betulus, Quercus cerris, Quercus frainetto. The bush floor is well developed, with the participation of Fraxinus ornus and Acer campestre. In the lower areas, in the xerothermic forest ecosystems, there dominate mixed forests of oak and Quercus, and on the sunny slopes – secondary forest

page 78 of 156

ecosystems of Oriental Hornbeam (Carpinus orientalis). The grass floor is composed of Poa nemoralis, Mycelis muralis, Lathyrus niger, Brahipodium pinnatum, Ruscus sp. etc. Along the rivers there are Salix alba, Ulmus minor, Populus nigra.

The arable land crossed by the route in this area are sown with alfalfa, wheat, sunflower and peas. There are areas occupied by vineyards.

In the past the Danube plain floristic region was occupied by xerothermic oak (Quercus) forests. Today the greater part of its territory is arable land. The open areas along the route are occupied by habitat 6210 Semi-natural dry grass and bush associations on limestone rocks (Festuco-Brometalia), (*important habitats of orchids) and habitat 6250 *Pannonian loess steppe grassland communities. Habitat 1530 * Pannonian salty steppe and salty swamps is encountered on the flooded lowlands in locations with spring floodings alongside the bigger rivers in the region. The species composing it are: Artemisia santonicum, Limonium spp., Camphorosma monspeliaca, Plantago tenuiflora, Juncus gerardi, Taraxacum bessarabicum, Trifolium fragiferum, T. echinatum, Cynodon dactylon,Mentha pulegium etc.

Most of the forests in this region are planted (acacia, pine, etc.), but there are natural forests as well. The dominating species in the forest areas are Pinus sp., Ulmus minor, Carpinus betulus, Acer campestre, Crataegus monogyna and Rosa caninа. In this floristic region there develop sub-continental xerothermic oak forests with prevailing Quercus cerris and Q. frainetto, which belong to habitat 91М0 Balkan Pannonian oak (Quercus Cerris) / Chinkapin Oak (Quercus muehlenbergii). Beside the rivers, on periodically flooded alluvial soils there develop 91Е0 * Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae). The prevailing species are Alnus glutinosa and/or Alnus incana.

During the implementation of the project the following impacts on vegetation are anticipated

During construction

The vegetation in the construction strip will be completely destroyed. The impact on the forest communities in the construction strip will be permanent and adverse, for the grassy communities – temporary and reversible, as they will be fully recovered for a short period of time.

During operation

No impacts are expected on the grassy communities. It is quite possible, after destroying the root vegetation in the construction strip some invasive plant species to find favourable living conditions.

In the forest sectors of the route the negative impact will have permanent character in the easement strip with width 30 m in which the wood and bush vegetation will be regularly cleaned.

The fires represent the main risk for the vegetation (especially – the forest vegetation). In case of accidents during the construction phase some limited pollution with oil products from the construction and transport machines can be expected.

The impacts on vegetation will be limited up to minimum via application of relevant mitigation measures.

3.5.2. Fauna

page 79 of 156

The final version of the route, as well as the construction activities, conforms to the peculiarities of the wild fauns in the region. After conducting terrain inspections and evaluation of the species diversity along the route, the teams will identify the risks and will suggest mitigation measures for minimizing the impact on the animal world. For avoiding the disturbance of the different animal species in various periods of their life cycle, there will be restrictions when building the route, related to avoiding works during the mating/breeding and hibernation periods, circumvention of shelters, hollows, colonies, nests, etc.

For every faunistic group there are lists of priority and valuable species. They include the species of Annexes 2 and 4 of the Directive on Habitats (92/43/ЕС), the species included in Annexes 2, 3 and 4 of the Biological Diversity Act (BDA), as well as the species included in the Red Book of Bulgaria and IUCN.

By the implementation of the project the following impacts are anticipated

During construction

The construction activities on Nabucco gas-pipeline will cause deterioration and loss of habitats (feeding, propagating, resting and wintering) of different animal species. The impact will be permanent for wood and rocky habitats and along the safety strip. Cutting of old trees which could be resting, nesting or observation substrate for the birds along the pipeline route will have a negative impact on ornitofauna. For the open areas the loss of habitats will be temporary and reversible. A deterioration of riparian vegetation and macrophits is expected during the activities on river and wetland crossings.

Temporary fragmentized of all habitat types is expected during construction of the pipeline. Amphibians, reptiles, small mammals and birds are especially sensitive during the breeding season to this type of impact. It will be impossible for youngsters of ground nesting birds, amphibians, reptiles and small mammals occurring in the area to cross the construction strip. After cessation of construction activities most of the habitats will be restored. In forest areas the fragmentation will be temporary due to permanent deforestation of the safety strip. River crossing activities will temporary fragment the aquatic habitats. After cessation of the construction activities they will be fully restored. Construction of river barrages the fragmentation will be permanent and will interrupt hydrobiont’s migrations.

Disturbance of animals is expected due to construction equipment, traffic, human presence, and the noise and vibrations produced by them, lighting at night, etc. This may chase away some of the animals from their feeding, resting, breeding or nesting territory. This impact is particularly dangerous during migrations and the breeding season. Hydrobionts will be temporary chased from the area they inhabit due to disturbance caused by the increased turbidity during construction.

Destruction of nests and mortality of youngsters of birds during construction is possible. Most affected will be ground and bush nesting birds. Loss of individuals (turtles, small mammals etc.) trapped in the construction trench is possible as well. Loss of individuals of hydrobionts is expected during the river crossings.

During operation

Habitat fragmentation will be less pronounced because no obstacles on the route are expected. Fragmentation will be stronger in the forest habitats.

The only expected disturbance at this period is the clearing of the safety strip. The impact will be short term and temporary.

During an accident

Accidents will cause pollution of the environment; loss or fragmentation of habitats; disturbance of animals; expulsion of individuals from their habitats until their restoration; change in nutrition resources; loss of individuals. Most of these impacts will be localized and bound with the working area and where facilities are located. The project aims by the use of appropriate mitigation measures to minimize the impacts during construction.

3.5.3. Protected areas

The corridor selection report avoid crossing of some Natura 2000 zones and minimizes the length of the section crossing the zone, when such zone is crossed by gas pipeline elements.

The Table 3.5.3-1 presents the protected areas for conservation of natural habitats and of the wild flora and fauna, included in the list of Natura 2000 protected areas, affected or crossed by the gas pipeline route.

The total length of the route crossing Natura 2000 protected areas is 48 km or 11.65% of its total length (412 km).

For the crossing of Natura 2000 zones the project team will develop a detailed route corridor and will select and plan suitable time periods and methods of construction in order to prevent and minimize any impact on Natura 2000 zones, the species and habitats subject to protection in these zones.

In accord with the national and European environmental legislation the expert team will prepare an Appropriate Assessment (AA) report in the frames of the EIA procedure. The AA report will represent an additional annex to the ESIA report and will access the potential impact of the project to the protected zones of Natura 2000 network. The AA report will analyse each one Natura 2000 zone separately and will contain:

3.6. Landscape and visual impact

The main factor for the landscape differentiation of the territory is in the interaction of relief, climate and vegetation, with priority of the relief. This is most valid for the natural complexes, i.e. those considered conditionally unchanged by anthropogenic activity. The various economic and other human activities have caused considerable anthropogenic impact on the nature landscapes. In the considered area, the biggest changes on the initial landscapes have been caused by the farming activities.

When describing the existing condition of the landscape in the affected territory, the publications of the Bulgarian Academy of Sciences (BAS) on Bulgarian geography, map sheets and publications in specialized literature was used.

According to the landscape regional division of Bulgaria (1989) the route of Nabucco gas pipeline passes through 3 regions, 11 subregions and 22 areas:

A. North Bulgarian zonal region of the Danube plain

І. Northern Danube plain sub-region – 3 areas

ІІ. Southern Danube plain sub-region – 4 areas

IV. Popovo-Shumen-Frangen sub-region - 2 areas

B. Balkan mountain region

VI. Central Balkan sub-region - 1 area

VII. East Balkan sub-region - 5 areas

VIII. Coastal-Balkan sub-region - 1 area

C. Inter-mountain zonal region of South Bulgarian lowlands and low mountains

XIX. Upper Thracian sub-region - 2 areas

XXI. Sakar-Dervent sub-region - 1 area

XXII. Bakadzhik-Hissar sub-region - 1 area

XXIII. Burhas-Aitos sub-region - 1 area

XXIV. Strandzha sub-region - 1 area

In the considered region there are 20 groups of landscapes of the four classes: plain, inter-mountain plain-lowland landscapes, kettle and mountainous landscapes, according to the typological classification system of landscapes in Bulgaria , built on geomorphological, mesoclimatic and phytogeographic features.

As a result of the economic activity of man, a part of the natural landscapes have been transformed. The natural landscapes in the urban areas have turned to anthropogenic, urban. The infrastructure construction also contributes to the anthropogenization of the landscapes. The areas where mining of mineral resources is developed, have acquired technogenic character. The cultivation of various farm crops has turned the landscapes in the respective areas into agrarian.

page 83 of 156

During the implementation of the project the following impacts are anticipated:

During construction

Disturbance of the relief due to the excavation works and creation of temporary negative forms (trench for the pipeline) and positive forms (from the temporary stockpiling of the humus soil layer and soil sublayer);

Disturbance of the natural vegetation cover and habitats;

Disturbance of the existing land use.

As the construction site of the pipeline moves forward relatively fast, the disturbances will be limited in the frame of several months for a given sector of the pipeline route; the vegetation in the zone of the impact of the construction works will recover relatively fast after carrying out the respective recultivation measures.

After recultivation of the built pipeline route

In case of correctly conducted recultivation activities and their conformity with the character of the respective damages maximum approach to the natural landscape can be expected;

Despite of the recultivation measures, the forest vegetation in the construction strip will be damaged during construction; the cuts in the forest areas will remain also during the operational phase of the project;

Some manifestations of erosional processes I the hilly and mountainous sectors of the pipeline route can be expected. The mitigation measures and recultivation activities will be part of the recultivation plan.

During operation

No impacts to landscape are expected during the operational phase of the project.

3.7. Cultural, architectural, historical and archaeological heritage

The analysis of the status of the cultural heritage items along the optional routes for the Nabucco transit gas pipeline requires a specific approach in the work on gathering and processing of information. The character of the investment initiative requires studying a narrow zone, crossing Bulgaria from southeast to northwest, passing through areas of quite different geographic characteristics. The level of knowledge of the separate areas is different. This determines the lower concentration of the items which came to be famous in certain districts, as well as their type and chronological diversity.

The survey of the status of the cultural heritage items along the optional routes for the Nabucco transit gas pipeline is based on information taken from the registers of the National Institute of the Immovable Cultural Heritage (NIICH), on information gathered from the National Institute of the Cultural Monuments for corridor of 4 km (two kilometer strip from each side of the central line of the pipeline route), as well from the computer information system “Archaeological map of Bulgaria”, from specialized publications and Internet. A part of the items have been identified after a detailed inspection of the topographic maps. The prepared ortho-photographies of the terrain along the whole gas pipeline route have been analysed.

page 84 of 156

As a result of the processing of the available information it was established that in 4 km corridor of the Nabucco transit gas pipeline can be affected potentially and to a different extent 143 items of archaeological immovable cultural valuables. In order to prevent or minimize the risk of affecting these archaeological items, it is envisaged during the design studies, according the Law on Cultural heritage (Art. 161, item 1), to carry out detailed archaeological surveys (total inspection) along the identified preferred route, on the grounds of which the final route of the 500-meter corridor will be defined.

During the implementation of the project the following impacts are anticipated

During construction

Specific terrain archeological observation and study will be carried out in order to localize the immovable cultural valuables in the borders of the construction strip and to prevent any impact to archeological objects, as well to discover unknown potential cultural monuments.

During operation

During the operational phase no adverse impacts to the cultural and archeological monuments are expected.

In case of accidents

No adverse impacts to cultural and archeological monuments are expected.

page 85 of 156

3.8. Harmful physical factors

Noise

The sources of noise in the territory, through which the route of the future gas pipeline is passing, are the transport flows on the main roads of the Republican road network:

Highway Trakia (Thrace) (LOT 3 in a project) and „Hemus” (in project);

First class roads: І–3 Sofia – Pleven, І–4 Sevlievo-Targovishte, І–5 Veliko Tarnovo – Ruse, І–6 Sofia-Burgas и І–7 Shumen-Elhovo

Second class roads: II-11 Mizia-Oryahovo, II-35 Pleven-Lovech, II-51 Voditsa-Popovo, II-53 Voynika-Sredets and II-79 Bolyarovo-Sredets.

The pipeline route also crosses sectors of three main railway lines: Sofia-Burgas, Sofia-Varna, and Gorna Oryahovitsa-Ruse.

The background noise in the contact sectors of the route’s crossings of motor and railway lines is determined by the noise emitted from the vehicles on them. In the remaining sectors of the gas pipeline, where there are no noise sources, the noise background is the natural background of the environment.

Areas with noise limit values, as required by regulations

Near the route of the future gas pipeline and along all of its length (in both options) there are areas with regulated requirements regarding noise – housing and industrial-storage areas of settlements. The settlements are mostly villages. Their housing areas are at various distances away from the gas pipeline route – from 200 m to 2250 m. The industrial-storage areas are small in number and located at distances from 180 m to 1 400 m from the route.

The gas pipeline route does not cross of the regulated (allocated for construction as under the law) areas of the settlements.

The noise limit values of the various areas and town planning zones (the hygiene norms) are stated in Ordinance No. 6 on the noise parameters in the environment, taking into account the degree of discomfort during the different hours of the day, the noise limit values, the methods for evaluation of the noise parameters and the harmful effects of noise on public health – Ministry of Health, Ministry of Environment and Water, Official Gazette No. 58/2006.

According to this regulation the limit values for noise in residential areas are: in daytime – 55 dBA, in the evening – 50 dBA, at night– 45 dBA, and for the industrial-storage areas – daytime, evening and night - 70 dBA.

During the implementation of the project the following impacts are anticipated:

During construction

During the contraction phase carious technique with specific noise characteristic of the machines and equipment will be used. It is possible that during digging the trench to be used detonation works. Relatively low impact of the noise to the environment is expected, only during the working hours of the day, without negative effects to population.

page 86 of 156

During operation

In case of normal operation of the linear parts of the pipeline no noise will be generated and no impacts to population and environment are expected.

The project envisages construction of the following above ground facilities located in special buildings: two gas metering stations, one inter-system connection, two Pigging stations and 14 block valve stations. It is expected the level of the generated by these facilities noise to be in the frames of the admissible norms.

Vibrations light, heat, electromagnetic and sound emissions

The main sources of these physical impacts are active during the construction phase. Usually the machines generating increased noise levels are also sources of vibrations, thermal, electromagnetic and noise emissions, which are factors of the working environment. For the natural environment they do not affect, because they quieten down at very short distances from their sources.

The emissions of the above harmful factors are expected to be within the requirements of the respective regulations and the protection from them is expected to be limited to the personal protection equipment (PPE).

3.9. Health and Hygiene aspects

Ordinance No.7 on the hygiene requirements for health protection of the urban environment (promulgated in 1994, amended and complemented in 2000) has no requirements as regards the hygiene-protection area of a pipeline or its related facilities. In the Ordinance on the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and devices for natural gas (promulgated in Official Gazette No. 67/2004) the minimum distance to urban areas and sites is 200 m. As a whole the gas pipeline avoids settlements and residential areas. According to preliminary data the requirements on the minimum distance are fulfilled. The construction and operation of the gas pipeline are not expected to enforce a hygiene protection status on residential areas. The preliminary survey established that near the pipeline route and its facilities there are no zones and/or items of specific hygiene protection status, or subject to health protection.

It is not expected the construction and operation of the gas pipeline to enforce hygiene-protection status of the residential areas.

During the implementation of the project the following impacts are anticipated:

During construction

- exhaust gases from internal combustion engines (mainly during construction);

- dust in the air (mainly during construction);

- noise: from the use of various equipment with specific characteristics.

These impacts are expected to be relatively low, only during working hours and without affecting the urban areas.

page 87 of 156

During operation

During normal operation of the gas pipeline and the related facilities no noise is expected to be generated, which could exert any impact on the environment and the urban areas. The generated vibration will impact the working environment only.

The performed preliminary study established that there are no zones and/or objects located close to the pipeline route with specific hygiene-protection status or subject of health protection.

3.10. Social aspects and land use

The proposed 500-meter corridor crosses the territory of nine districts, which are within the boundaries of four out of the six national planning regions – Southeast (Burgas – municipalities Sungurlare, Sredets; and Yambol – municipalities Straldzha, Bolyarovo), Northeast (Shumen – municipality Varbitsa; and Targovishte – municipalities Antonovo, Omurtag, Popovo and Targovishte), North Central (Veliko Tarnovo – municipalities Gorna Oryahovitsa, Pavlikeni, Polski Trambesh and Strazhitsa; and Ruse – municipality Byala), and Northwest (Pleven – municipalities Dolna Mitropolia, Dolni Dabnik, Iskar, Knezha, Levski, Pleven, Pordim; Lovech – municipalities Lovech, Letnitsa; and Vratsa – municipalities Oryahovo, Mizia).

The nine districts are relatively sparsely populated. The bigger towns are also the very district centers, but the route of the designed gas pipeline crosses the land mostly of villages with small exceptions. The town of Popovo with population 15548 is the biggest settlement, the land of which is crossed by the designed gas pipeline route.

The designed gas pipeline route crosses districts and municipalities of various social-economic characters.

In the Southeast planning region the farm land occupy 57%, and the forest land – about 34% of the territory. In the remaining three regions the values are similar – 68-69% of farm land and 22-24% of forest. More detailed information about the category balance and the method of lasting use of the lands, crosses by the gas pipeline route are indicated in section 1.1.2.

The GDP per person in currency (BG leva) for each of the nine districts is quoted in the table below:

The sectoral economic profile of the Southeast region shows that in the primary sector, agriculture stands out with grain and livestock specialization, and further growing industrial crops and perennial crops. In the secondary sector several specialized industries form over 90% of the industrial production - the production of oil products, chemical products and fibers; food, beverages, tobacco products, manufacture of transport equipment, metal products and machinery, textiles and knitwear. In the services sector prominent position take transport, recreation and tourism.

page 88 of 156

In the Northeast region the primary sector is also grain-livestock oriented, with grain and industrial crops strongly dominating. The secondary sector marks a long period of decline. Leading specialized industries are food, beverages and tobacco, chemical products and fibers, products from industrial minerals and energy. The tertiary sector is well developed with a significant share of transport, communications and tourism

In the North Central region agriculture and forestry form the primary sector. The highest proportion in the secondary sector take the production of food, beverages and tobacco , followed by the production of metal products and machinery, chemical products and fibers, as well as of industrial minerals. In the tertiary sector of greatest economic importance are public health, education and transport.

Without changes, the primary sector of the Northwest region is also dominated by agriculture with grain-livestock orientation, with a certain share for industrial crops. From the branches of the secondary sector the leading position is for power generation, gas and water supply, as well as food production, beverages and tobacco products, production of industrial minerals, metal products and machinery, textiles and knitwear. The Northwest region is economically the most backward of all six in the country, which reflects the strongest also on the tertiary sector, especially in branches such as public health, education, trade, etc.

According to current data, the number of employees and average monthly wages for the different areas in the planning regions are outlined in the attached table:

The population of the nine areas accounts for 27 percent of Bulgaria's population. It is concentrated in the big towns and in the municipal centers. The proportion of men is 48.5% and is slightly larger than that in the country.

Of all areas/districts, only Burgas has a mechanical positive population growth (12.3 %). In the others the mechanical rate is negative, in Veliko Tarnovo and Ruse reaching 15%, in Shumen, Pleven and Vratsa - 30%, and in Targovishte, Lovech and Yambol - over 45%. The area with the highest negative mechanical rate is Yambol with 53.7%, thus the areas at the two end of list - Burgas and Yambol – belong to the same planning region.

The proportion of minorities varies in the different areas. The number of the two biggest minorities – ethnic Turkish and gipsies (Roma) population - is presented in the table below:

The 500-meter corridor crosses Bulgaria from southeast to northwest. It passes through areas with the following characteristics of land use:

Agricultural land (fields, orchards, vineyards, etc.);

Forests and bushes;

Meadows and pastures;

Other (roads, rivers, environmental infrastructure, built-up areas, etc.)

Most of the land is for agricultural use, followed by the part occupied by forests and bushes.

The land for the sites of the above ground facilities (block valve stations, gas metering stations, etc.) will be acquired by Nabucco Gas Pipeline Bulgaria EOOD, while the land, which is crossed by the pipeline, will remain property of their owners, and the route corridor directly above the pipeline will be protected with easement. The owners of these lands will be compensated for long term losses and lost profits during construction and operation of the pipeline, as per legal provisions and the market environment.

For security reasons and in accordance with the requirements of the Ordinance on the construction and safe operation of the transport and distribution gas pipelines, of the facilities, installations and devices for natural gas, it is planned to have a permanent easement area around the gas pipeline with the following width:

For agricultural land - 36 m, where it will be allowed to sow only annual crops;

Forest – 18-32 m.

In the easement strip is not permitted to perform construction, cultivation (plowing) of soil to a depth greater than 0.5 m, kindling of fire, planting of vegetation with a developed root system at less than 15 m from the pipeline axis. After written consent of the holder of easement rights, limited construction activities are allowed for other linear items, intersecting or parallel to the pipeline.

A protected area will be established on both sides of the pipeline system, with a regime of preventive protection of the facilities as under Art. 10 of the Spatial Planning Act (SPA).

Width of the protection zone of 400 m (200 m on each side of the pipeline);

The minimum distance from single buildings and other items to the pipeline will be 125 m.

The operator will be entitled to permanent access to the facilities and equipment for inspection and maintenance.

During the implementation of the project the following impacts are anticipated

During construction

page 90 of 156

Employment of local work force; Increase of demand of resources and procurement of goods and services in

the nearest settlements to the construction camps; Increase of the qualification of the local workers occupied during the

construction of Nabucco gas pipeline; Temporary overloading or interruption of infrastructural elements; Temporary traffic increase of the roads leading to and from construction

camps and construction yards; Temporary limitation of the land use rights on the land in the 36 m

construction strip; Lost of crops in the agricultural lands in the 36 m construction strip.

During operation

No considerable negative impacts to the social-economic environment are expected. Some positive potential impacts can be identified – for example creation of long term working places (in the metering stations, pigging stations, gas metering stations, repair-maintenance teams, etc.), realization of a diversification of the gas supply to Europe (including Bulgaria), etc.

4. 4. SIGNIFICANCE OF THE ENVIRONMENTAL IMPACTS, IDENTIFICATION OF THE INEVITABLE AND PERMANENT ENVIRONMENTAL IMPACTS BY THE CONSTRUCTION AND THE OPERATION OF THE INVESTMENT PROPOSAL, WHICH CAN PROVE TO BE IMPORTANT AND SHOULD BE TREATED IN DETAIL IN THE EIA REPORT

The impact assessment is a logical and consistent (step-by-step) process. Its main objective is to calculate and foresee the consequences of the activities related to a given project, by identifying also the specific mitigation measures to combat the harmful impacts, so that the follow-up control could minimize this impact.

4.1. Character of the impacts

In determining the impact a common methodology will be applied, which meets the requirements of the Bulgarian legislation and the good international practices for assessing the environmental and social impacts. It takes into account:

1. Sensitivity of the receptor (host environment) - local, regional, national, international;

2. Probability of the occurrence of impact – expected, not expected ;

3. Territorial scope of the impact – within the trench, the construction site, the easement strip, local, transboundary;

4. Type of impact - positive / negative and direct / indirect, primary and secondary;

5. Degree (significance) of the impact in 6 grades: 0 – null, 1 - very low, 2 – low, 3 – medium, 4 – high, 5 - very high degree.

6. Characteristics of the impact. It includes the following:

Frequency - permanent, temporary ;

Duration – short term, long term .

Cumulative action - impacts that act together and affect one and the same environmental component or receiver. They are:

a. Accumulated (accrued) - effects of different components on one host environment;

b. Summed - impact with the background of the impacts of other projects, implemented or forthcoming in the foreseeable future;

c. Interactive – impacts, acting or capable of acting on each other.

7. Reversibility of the impact – reversible, irreversible.

The impacts on the environmental components and the human health in the realization of the investment project will be determined in the EIA report, based on:

- Data on the type and quantity of the generated waste and emissions as a result of the realization of the investment proposal;

- Recent data on the status of the environmental components;

- Expected changes in the environmental components and factors during the realization of the investment proposal;

page 92 of 156

- Health aspects of the expected impact;

- Social aspects.

Special attention will be given to the measures for preventing, reducing or compensating the anticipated negative impacts on the environmental components.

4.1.1. During construction

Expected impact on the following components:

GEOLOGICAL BASEMENT -  negative, direct, permanent; degree of impact (or significance) – low;

SOIL – the impacts are negative, direct, long term (during the period of construction of the pipeline), temporary, reversible for a certain period after recultivation; degree of impact – from low to medium;

LANDSCAPE – the impacts are negative, direct, short- and long-term, permanent and temporary, and partially reversible after recultivation; degree of impact – low;

FLORA and FAUNA – the impacts are permanent (in the cases of loss of trees and nests in the places of permanent above ground facilities), reversible in a long period of time after recultivation; when crossing Natura 2000 protected areas in case of proved feasibility: the impacts are inevitable and partially reversible after recultivation;

SURFACE WATER – when crossing rivers and other water bodies (with proven feasibility) the impacts are partially reversible in strict compliance with the technological requirements of the respective method of laying the pipes;

AMBIENT AIR – the impacts are limited, when observing the legal requirements and envisioned measures; reversible after the construction of the gas pipeline system;

NOISE – the impacts are limited, when observing the legal requirements and envisioned measures; reversible after the period of construction;

CULTURAL HERITAGE – a significant number of cultural heritage items – mainly archaeological, can potentially be affected during construction of the pipeline. The scope of impact is within the easement of the gas pipeline, passing through the territory of these items and their protection zones. When performing detailed archaeological surveys (with a total detour) and, when needed, of rescue excavations, the degree of impact from high becomes very low.

WASTE – all types of waste will be delivered to licensed companies and no impact of waste to the components of environment are expected;

HARMFUL PHYSICAL FACTORS – the impacts of the physical factors are short term and reversible. Their significance is limited by the used personal protective equipment (PPE)

The main scope of impact is an area with length of about 412 кm and width from 30 m to 36 m. The area of the gas metering stations is expected to be 1.2 ha, of the gas pigging stations – 2 x 7.5 ha, and that of the temporary camps – 5.0 ha. The EIA report will study the scope of the environmental and social impact, by taking into account their specifics.

4.1.2. During operation

page 93 of 156

No negative impacts are expected, when observing all the technological and engineering requirements and performing the envisioned measures for eliminating or limiting the harmful influences.

4.1.3. Accidents

No risk of potential accidents such as breakthrough of gas pipelines is expected. Incidents such as ruptures, and subsequent leaks and fires have been established only in the consumer gas distribution networks or their facilities, and have been caused by third parties.

All potential emergency situations are controllable from the overall SCADA system. The project includes the preparation of safety plans, fire-fighting plans, plan in cases of terrorist attacks, etc.

4.2. Assessment of the potential impacts

The EIA report will make an evaluation of the potential impacts on each of the environmental components and the human health.

4.3. Environmental Management Plan

4.3.1. Measures for averting or reducing the significant environmental impacts

In ESIA report will be developed a proposal for environmental and social environment management and monitoring plan, which will include a program for implementing the measures and monitoring during the various stages (activities in the feasibility studies for the design, construction and operation the pipeline.

The gas pipeline project envisions facilities, programs, activities and procedures related to reducing the negative environmental impacts and preventing the emergency situations. Different measures will be implemented at various stages of realization and operation of the project.

Even at the design stage, the choice of route takes into account the urban areas, the protected natural sites, the water sources for drinking water, and other similar restrictions. Along the route are identified the environmentally sensitive areas and for them the project will envisage additional measures for mitigating the impacts during construction and operation.

The Nabucco gas pipeline system includes the following elements, which will reduce the environmental risk from the project’s realization:

1. Main command center, located in Ahoboz, Turkey, for control of the gas pressure and flow in the pipeline system, and a reserve one in Baumgarten, Austria. There will be intermediate centers in all of the transit countries, including Bulgaria.

2. The SCADA control system processes the data from the operational work of the pipeline and the above ground facilities, remotely controls their status, shows abnormal or emergency conditions and issues online warnings. SCADA is independent on the system for emergency shut down of the gas flow and the fire & gas safety system.

3. Linear block valve stations (stop valves) and a system for their control, which secures the isolation of separate gas pipeline sections and in this way increases the safety of the facility and reduces the environmental risk in operating conditions.

4. The inner surface of the gas pipeline will be inspected in regular periods via Pipeline inspection gauges (PIG), which move inside the gas pipeline and check its mechanic condition. The results of these inspections will be entered in the

page 94 of 156

SCADA, system, which will process them and in the event of problems the operator will receive an early warning for potential problematic sections of the pipe (e.g. sectors with observed corrosion).

5. Passive measures are also envisaged for preventing of / reducing the risk of accidents with the gas pipeline – by using pipes made of high quality steel, with special construction of the pipes capable of withstanding the high tensions, special insulation in the form of a protective mantle of the pipes, anti-corrosion and conductive insulation, etc.

6. An Emergency Response Plan will be developed for the operational phase of the project, as well as local safety measures.

For the construction phase the designer envisages the following measures for reducing the negative environmental impacts:

Work in a construction strip with reduced width (30 m) when passing through environmentally sensitive areas (forests, protected natural sites, etc.). Develop a special plan for mitigation measures and subsequent monitoring.

Technical and biological recultivation of the construction strip immediately after completing the construction activities;

Special measures for preserving and storing the humus soil layer and restoring the soil fertility;

Implementation of trenchless methods of crossing infrastructure items;

Anti-erosion measures when crossing rivers, disturbed and bare terrains with developed erosion or high risk of erosion;

Work with machines and equipment in good technical condition, which correspond to the requirements of the Bulgarian laws and European regulations;

When blasting works are required, to use an environmentally sparing method – the method of micro-charges. Develop a special plan for mitigation measures and follow-up monitoring (if required one);

Supervision by archeologists during the implementation of the excavation works for archeological objects located close to the construction strip, but out of the range of the planned excavation works. Boring surveys in designed sectors, rescue excavations in the frames of the easement strip and complete archeological research for objects like tumuli, for which even a peripheral disturbance can lead to their discredit and impossibility for their further protection.

Use of local work force, services and materials;

Careful planning and coordination with the responsible national and local authorities of eventual cuts and disturbances of the local infrastructure (crossing roads, power lines, plumbing, etc.).

The negative environmental impacts are anticipated during construction. It is believed that during the operation of pipeline in compliance with all technology and technical requirements negative impacts will be insignificant.

Additional measures for prevention and mitigation will be proposed in EIA report , which will be respected in the construction and operation of pipelines and facilities thereto.

4.3.2. Monitoring plan

page 95 of 156

The monitoring plan will include the most vulnerable components of the environment, including air, water, biodiversity, etc.

page 96 of 156

5. 5. PROPOSAL FOR THE STRUCTURE OF THE EIA REPORT

The scope of the EIA report will include a description of the status of the environmental components, as per Art. 4 and Art. 5 of Environmental Protection Act and estimate of the project’s impact on each one of them. The factors that pollute or damage the environment will be identified, with pointing out the ways of reducing or preventing the negative impacts. The EIA report will be formed as one single document in accordance with Art. 12 of the Regulation on the Conditions, Procedure and Methods for Environmental Assessment of Plans and Programs for investment proposals for construction, activities and technologies.

Together with EIA report will be submitted the conformity assessment, as provided by the Biological Diversity Act and the Regulation on procedures for appropriate assessment of plans, programs, projects and investment proposals with the scope and purposes of protected areas conservation.

Response: Letter 269/17.02.10 -

II. From the Technical design – general information on page 3 "Main components", item 4 it is quoted – Connection of Nabucco gas pipeline with Chiren underground gas storage, including the gas measuring station.

Chiren underground gas storage is in the land of the village of Chiren, Vratsa municipality. It is necessary to:

1. Provide clarification and take into consideration in the future ToR for EIA, respectively in the EIA Report, whether the connection of Nabucco gas pipeline with Chiren underground gas storage will be considered;

2. To point out the route of the gas pipeline connection for every land of the villages, in order for us to inform you whether it passes through protected areas or protected territories.

III. A part of the pipeline route on the territory of Vratsa district, according to the submitted information, passes through protected area “Ogosta River” with ID code ВС0000614. The protected area is identified as per Art. 6, par.1, item 1 and 2 of BDA on protection of the natural habitats and the wild flora and fauna, and is included in the list of protected areas, approved by Decision No. 122/02.03.2007 of the Council of Ministers.

On the grounds of Art.31, par.1 of BDA and as per Art.2, par.1, item 1 and par.2 of the Ordinance on the environment, the terms and procedures for making conformity assessments of plans, programs, projects with the scope and objectives of the protected areas /promulgated in Official Gazette 73 / 11.09.2007/ the investment proposal is subject to a procedure for conformity assessment with the scope and objectives of the protected areas .

1. The EIA report considers present stage of the construction of Nabucco gas pipeline, in which the connection to the Chiren UGS is not envisioned. This connection will be realized at a much later stage, when the gas pipeline system will have been built and the flow of gas will have reached its maximum capacity.

2. In both the ToR and the EIA report there will be map sheets presenting which land the gas pipeline is passing through.

Responses: Letter 2947/22.07.09 – to add PAs Sedlarkata and Dolni Dabnik dam, to work out the sections “air”, “waste”, and Letter 547/17.02.10=49-00-012-2/22.02.10 –special attention on protected territories and zones

page 109 of 156

I. Regarding component “Ambient air":

Along the route passing through the territory of RIEW Pleven, the project envisions to mount 4 stop valve units /option of the route /. In specific circumstances /accidents, ventilation of the section/ there is the probability to contaminate the air in these areas with gas. It is not clear what quantities of gas can be expected to be released in the air, and to what degree this would impact the air quality.

It is necessary to define the conditions for using the stop valve units when ventilating the pipelines or in an accident, due to which release of methane can be expected, with limiting its impact as a greenhouse gas.

II. Regarding component "Water":

The EIA report should treat with attention:

1. Sites, on which the facilities for treatment of household waste water will be installed.

2. All locations of crossing water bodies – one should keep in mind the necessity to get permits for the use of water bodies.

III. Regarding component "Waste":

1. To identify all kinds of waste, which will be generated by the activity, including waste generated during repair works and maintenance of the facility (including waste of packaging of products necessary for its service and maintenance), according to the requirements of the Waste Management Act (WMA) (Official Gazette 86/2003) and Ordinance No.3 on classification of waste.

One should keep in mind that:

The Construction waste should be managed in compliance with the Waste Management Act (Art.18 of WMA).

The Household waste should be managed in compliance with Art. 6 and Art.16 of the Waste Management Act.

The generated waste should be collected, stored and transferred for treatment in compliance with the Waste Management Act and the respective secondary legislation.

IV. Regarding component "Soil":

1. It is necessary to underline the necessity to comply with the provisions of the Law

The activities for cleaning the gas pipeline are carried out without polluting the surrounding terrain. The gas emitted in the air is lighter than air and dissipates in the air space.

The sectioning through stop valves has the purpose, in case of accidents, to limit (by the stop valves) the leaking of gas from the section where accident has occurred, which otherwise would flow out of the rupture and, if there are no sections, the whole quantity up to the previous stop valve will be emitted in the air.

The quantity in case of accident for a 20-km section is 2.864 x10^6 of cubic meters.

To take measures for minimum impact on the available forest fund. Suggestion – to drop Nature Area (NA) Dryanivska cave, PA Studena River, and to add PA Golyama River.

And Letter No.1716/12.02.2010 from RIEW Veliko Tarnovo:

The ToR should include detailed information on the crossed water bodies, bio-areas, and the existing linear infrastructure. For the construction phase – to envisage an assessment of the dust and noise emissions and their impact on urban areas.

PA Dryanovska cave is over 30 km of the 500-meter corridor of the preferred route

Minimum impact on the available forest fund is one of the main criteria for selecting the route. When passing through forest localities, the easement zone is reduced to 30 m

Yes, the EIA report will contain detailed map information on the mentioned items. The dust and noise emissions during construction will be estimated in view of their nearness to urban areas

M.D. Chankova (Regional Inspection for Protection and Control of Public Health - RIPCPH Shumen):

The project route passes close to Ticha Dam - at what distance from it and the SPZ belts 2 and 3

Krassimira Maneva („W&S” - Shumen):

The pipeline route is in belt 3 of the sanitary protection zone (SPZ) of Ticha Dam. At the moment there are no coordinates available for the belts around the dam, there is a scheduled project for making measurements and establishing coordinates of belts 2 and 3. It is expected that belt 3 is 25km, and “Irrigation systems” Shumen is the owner of Ticha Dam

Ivan Ivanov (Municipality Varbitsa):

When the route passes through forest, who grants the permit for passage

Waiting for reply from „Irrigation systems”-Sofia and Basin Directorate Black Sea region - Varna.

The Executive Forest Agency issues a permit for change of the use of the forest. „Chimcomplect Engineering PLC as design engineer requested and purchased detailed information on the type of affected forests. The route does not cross century old and valuable forests.

- What are the risks that the gas pipeline creates?

- What is the minimum admissible distance of the high pressure gas pipeline to urban areas?

The probability of risk or accident is minimal (0.056% per year). The strict compliance with the legislation and the safety requirements brings the risk of accidents to almost zero. The project has envisioned all the necessary systems for safety and monitoring during operation. Statistics shows that up to 70% of the accidents are due to unauthorized (not permitted) construction and excavation works.

The minimum distance from single buildings and other items to the gas pipeline is 125 m. The design route of Nabucco gas pipeline passes at considerably greater distance from urban areas.

- How will the soil be restored after construction? Part of the excavated earth mass should be removed so that no landfills are formed – where will it be collected?

-Rumen Zhelev, Regional Forest Directorate – We appreciate positively the alternative options with regard to the environment and the measures for preserving the protected areas.

The recultivation of the disturbed terrains is an important part of the construction phase – a separate project will be developed for it, including the depositing of the excess excavated material. The Head project designer Penspen will follow closely especially the execution of this part. Chimcomplect is collecting information from the municipalities about suitable locations.

One of the tasks of these meetings is to discuss the problematic issues and to seek the best solution.

In Golyamo Krushovo and Oman there are investment proposals, which will be clarified and information will be submitted further on.

- The set terms for construction of the gas pipeline coincide with the construction of Trakya highway.

- The Plan for Organization and Execution of Construction (POEC) should take into account the movement of heavy equipment and comply with the existing road network and local infrastructure. The plans for movement of the heavy machines should be coordinated with municipalities.

This is an important question, about which we ask the municipalities for their cooperation.

The Nabucco project engineers will fully conform to the existing infrastructure. There will be complete mutual exchange of information with Road Infrastructure Agency

-This problem is taken into account and it will be seriously treated in the design and preparation of the ESIA report.

- What will be the depth of drilling, for determining the density of the earth mass along the route?

District administration Vratsa:

- What will be the procedure in case of discovery of an archaeological finding?

- We are not worried about the project development, but we hole that it will help in discovering significant archaeological findings such as Malak Kochan – an ancient settlement and mound in our land.

The information about their schedule will be coordinated with the municipality mayor. Drilling is mandatory when crossing first class and second class roads of the republican road network.

- even at the design stage we will survey the corridor for the presence of immovable cultural valuables, and an estimation will be made as to how they will be preserved. Constant monitoring will be performed in coordination with the local and national concerned institutions.

- The principles which the investor and the head project engineers keep to, are to clarify all social aspects even at the design stage, and this to be done for the benefit of the public.

If a given archaeological site is at risk, all the measures required by the respective law will be taken to preserve it.

Does the route cross Natura 2000 areas in the municipalities of District Targovishte, and the area „Golyama River”?

No, the route does not affect Golyama River protected area. Moreover, the map sheets show how the route “evades” the protected areas, because of them we made it longer – from 397 to 412 km, in order to avoid as much as possible the crossing of Natura 2000 areas. The plans for biodiversity protection envisage saving of turtles, bird nests during construction and their reinstatement after completing the construction of the pipeline.

Е-mail: 49-00-068/11.08.09 - request for proposals regarding the ToR for EIA

Response: Letter 59/7.09.2009 from the Information and training center on ecology

I. Regarding the protected areas of Natura 2000

The evaluation of conformity report should be based on the parameters pointed out in the „Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria ", developed in cooperation with and approved by MOEW. The guide is available in electronic form and can be submitted to the team responsible for preparing the assessment.

1. The report should give an assessment for every species and habitat, and for every parameter, about the size of the population and area of the habitats with regard to the reference value in each affected area and the size of affected habitats and populations .

2. For determining the reference values one should use at least all available GIS layers, which served to prepare the borders and assessment of the completeness of the Natura 2000 network. With regard to this, we are ready to present all layers used for the purpose and available with us, although these have been officially submitted to MOEW.

3. It is necessary to allow at least one active season for the experts’ field surveys.

4. The gas pipeline route should be studied with special attention, in order to avoid affecting priority natural habitats, and if necessary (exceeding the percentage of affected habitats by over 1% of the area in the zone) to seek new alternative routes with a joint expert team - experts on conformity assessment and engineers.

5. The same approach should be undertaken when eventually affecting the following especially sensitive and unable to be compensated components:

According to a response from MOEW to a Chimcomplect request for allowing access to public information, the „Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria " has not been officially confirmed by the Minister of Environment and Water. (Ref.No. ЗДОИД-8752 (26.10.2009). We have the „Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria " and we are familiar with the methodological approach suggested in it. The applicable criteria for each specific issue (species, habitats) will be used during the field surveys and in the assessment of the impacts and in the elaboration of the monitoring program. Due to of lack of benchmarks in some cases, it won’t be able to take some of the criteria in to account.

1. An assessment of the priority species and habitats will be worked out.

2. Have been used [GIS layers]

3. The field surveys comprise 2 seasonal inspections – autumn and spring.

4. The initial version of the route has been changed in order to reduce to a minimum the crossing of Natura 2000 areas, and the crossing is only in places, for which it is not possible to go around, and with minimum impact on the wild flora and fauna.

5. The remarks will be taken into account.

6. The remark will be taken into account

page 120 of 156

• Distances from nests of birds of prey (impact during the construction phase)

• Distances from rock massifs and narrow river valleys (not to allow direct damage and crossing of those sites)

• Passing parallel to rivers (to ensure a distance of minimum 200 meters from them)

• To prevent harm to isolated colonies of ground squirrel and deposits of invertebrates.

6. For all areas where the subject of protection is land turtles, to provide during the construction phase temporary collection of the turtles from the route strip and to place them back in the locations where they were found after completion of construction.

7. To plan recultivation of the route with seeds of grass species, typical of the natural grass ecosystems for the respective region.

8. Such a large scale project requires the hiring of a team of experts, with an experienced expert for each main group of organisms, as well as a GIS expert to support the team in the assessments. We do not recommend hiring experts, whose professional objectivity is questionable – such experts, who in the last year have prepared assessments without taking into account the „Guide for assessing the favourable conservation status for habitat types and species in Natura 2000 in Bulgaria " and also such experts, who have worked out too many assessments in a short period of time.

II. Regarding the social points of conflict

Because of the lack of texts in the Inter-govenrmental agreement, settling the possible evacuation of citizens, acquisition of land for the project’s needs, and compensation for damages caused by construction and operation of the project, we recommend that the above are treated in detail in the EIA report.

7. Such seeds cannot be provided in the necessary quantities. The recultivation will be performed with other species suitable for the purpose. The rest of the proposals will be taken into account.

8. For the assessment of the project’s impact on the wild flora and fauna a large team of experts has been hired, and in various aspects: phytocenologists, experts in invertebrate fauna, ichthyologists, herpetologists, ornithologists and experts in mammals, as well as GIS experts.

The project does not envisage any resettlement activities of the local population along the pipeline route, as the route does not cross settlements.

1 The EIA report should include and analyse the Nabucco alternatives for reaching the same

1.Given the commitments undertaken by Bulgaria in implementing the Nabucco pipeline, alternatives in energy efficiency and renewable energy sources are not a subject of EIA report, because of the fact that it considers only first stage of the system construction.

page 121 of 156

targets, which Bulgaria has set itself. More specifically, to evaluate what are the energy alternatives of the amounts of gas, which Bulgaria will use for its own purposes. We suggest analysing with priority the alternatives “energy efficiency” and “renewable energy sources”. For the moment there is no information what amounts of natural gas will be supplied to Bulgaria via the pipeline. Therefore it is totally impossible for the citizen organizations working on the problems of climate, energy and the environment, to evaluate the climatic effect of the use of gas from Nabucco for Bulgaria. We suppose that a similar problem is facing also the EIA experts, who will work out the report.

With regard to this, we would like to receive information whether a similar climatic effect is planned to be evaluated by Chimcomplect Engineering PLC, or by other Bulgarian or international experts. Also, whether a similar effect will be evaluated on an international level for the whole project. We would like to underline expressly that IGP does not consider as an alternative to Nabucco the proposed by Russia project South Stream, as long as this project, beside the common energy source (natural gas), which would produce the same effects, supposes also other significant for Bulgaria problems of political and geopolitical character.

2. The assessment of the impacts on the environmental components should be done separately for each of the stages of construction and operation of the gas pipeline. The hazards and the possible way of action to eliminate or minimize them should be stated explicitly.

3. More specifically, to make deep detailed assessment of the following components, factors and hazards:

• flora and fauna;

• surface and ground water;

• soil;

• landscape;

• risks of accidents (natural disasters which could affect the pipeline, explosions, terrorist attack);

• possible evacuation of citizens, acquisition of land and other changes of property for the needs of the project, and compensations for damages caused by the construction and operation of the facility, transitions and crossings, impact on agriculture (social and economic effects).

2. The assessment of the climate effects will be done by projects for common execution, separately for each of the countries, after reaching the full capacity of the gas flow through the pipeline – after realization of final stage.

3. This is the contents of every EIA report, as provided by the Bulgarian law.

4. The investor is currently developing the options for decommissioning of the pipeline. It is most likely that the way of decommissioning will be coordinated with each of the states of the common gas pipeline.

page 122 of 156

4. To evaluate the impact of the decommissioning stage and recultivation of the terrains. If such information is missing, to request from the investor to prepare and propose a plan of mobilizing the necessary financing for this purpose. It is not important when in the future this stage will happen.

В: Regarding protected areas of Natura 2000

Unless otherwise stated, we expect the Appropriate Assessment report to be part of the EIA procedure. In this connection, we recommend:

1. The Appropriate Assessment report (AAR) should be based on the parameters listed in "Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria", developed in cooperation with and approved by MOEW. The

1.According to a response from MOEW to a Chimcomplect request for allowing access to public information, the „Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria " has not been officially confirmed by the Minister of Environment and Water. (Ref.No. ЗДОИД-8752 (26.10.2009). We have the „Guide for assessing the favourable conservation status of habitat types and species in Natura 2000 in Bulgaria " and we are familiar with the methodological approach suggested in it. The applicable criteria for each specific issue

page 123 of 156

Guide is available in electronic form and may be granted to the team responsible for preparing the evaluation.

2. The AAR should provide estimates for each species and habitat per each parameter about the population size and area of habitats, with regard to the reference value in each affected area, and the size of affected populations and habitats.

3. For determining the reference values, to use at least all available GIS layers serving to prepare the borders and assessment of the completeness of the NATURA 2000 network. In this regard we are ready to provide all layers used for the purpose and available to us, although they have been officially submitted to MOEW.

4. It is necessary to allow at least one active season for the experts field surveys.

5. The gas pipeline route should be studied with special attention, in order to avoid affecting priority natural habitats, and if necessary (exceeding the percentage of affected habitats by over 1% of the area in the zone) to seek new alternative routes with a joint expert team - experts on conformity assessment and engineers.

6. The same approach should be undertaken when eventually affecting the following especially sensitive and unable to be compensated components:

• Distances from nests of birds of prey (impact during the construction phase)

• Distances from rock massifs and narrow river valleys (not to allow direct damage and crossing of those sites)

• Passing parallel to rivers (to ensure a distance of minimum 200 meters from them)

• To prevent harm to isolated colonies of ground squirrel and deposits of invertebrates.

7. For all areas where the subject of protection is land turtles, to provide during the construction phase a temporary collection of the turtles from the route strip and to place them back in the locations where they were found after completion of construction.

8. To plan recultivation of the route with seeds of grass species, typical of the natural grass

(species, habitats) will be used during the field surveys and in the assessment of the impacts and in the elaboration of the monitoring program. Due to of lack of benchmarks in some cases, it won’t be able to take some of the criteria in to account.

2. An assessment of the priority species and habitats is in a development phase.

3. We are thankful for the expressed readiness, and will take advantage of it, if needed. At the moment a second field survey by the respective experts is being conducted

4. The field surveys comprise 2 seasonal inspections – autumn and spring.

5. The initial version of the route has been changed in order to reduce to a minimum the crossing of Natura 2000 areas, and the crossing is only in places, for which it is not possible to go around, and with minimum impact on the wild flora and fauna.

6. The remark will be taken into account.

7.The remark will be taken into account

8. Such seeds cannot be provided in the necessary quantities. The recultivation will be performed with other species suitable for the purpose. The rest of the proposals

page 124 of 156

ecosystems for the respective region.

9. Such a large scale project requires the hiring of a team of experts, with an experienced expert for each main group of organisms, as well as a GIS expert to support the team in the assessments . We do not recommend hiring experts, whose professional objectivity is questionable – such experts, who in the last year have prepared assessments without taking into account the „Guide for assessing the favourable conservation status for habitat types and species in Natura 2000 in Bulgaria " and also such experts, who have worked out too many assessments in a short period of time.

will be taken into account.

9. For the assessment of the project’s impact on the wild flora and fauna a qualified team of experts has been hired, in various aspects: phytocenologists, experts in invertebrate fauna, ichthyologists, herpetologists, ornithologists and experts in mammals, as well as GIS experts.

80 Participant in technical meeting from Lovech municipality

Preliminary studies- hydrogeological studies- are likely to cause damage to property of different owners.Response: Such studies are performed in the periods in which the land is not cultivated and in the presence of the municipal committee. After completion of drilling the drilling crew must restore damaged areas to its original condition.

81 Participant in technical meeting from Lovech municipality

For growers, candidating on EU programs, can the route be deviated from their parcels? Response: There will be compensations for the annual crops. For the perennial is the same. Individual when planning the pipeline is designed to avoid perennial agricultural fields. Question of study are the relationships between the farmers and the European financial institutions and how they can avoid penalties from them.

82 Participant in technical meeting from Lovech municipality

For how long must the information materials for informational spots in the settlements be maintained? Response: Before and during construction in the municipality

83 Participant in technical

When the gas pipeline passes through the land of people, how they will be compensated? At the moment the price of land reaches 600 BGN/acre in a growing interest, how will the

page 128 of 156

meeting from Lovech municipality

compensations be negotiated?Response: The compensation will be based on current market prices. The land of the people will not be bought up (except for about 300 acres for surface facilities)- they will be compensated because the pipeline passes under their land and because during construction will have no harvest. Finally the soil is recovered and returned to the owner in the presence of competent authorities and with delivery-acceptance protocol.

84 Participant in technical meeting from Lovech municipality

The minimal depth spoken of is 1m. In deep plowing- 60cm aren’t you posing a risk and isn’t it better to lay the pipeline at greater depth? Response: At the moment there are power cables under agricultural land which is processed without problem. The planned depth of 1m is minimal and is sufficient to prevent the risks of deep plowing.

85 Participant in technical meeting from Lovech municipality

The restrictions on use should not affect the map materialResponse: The restrictions will be duly noted.

86 Participant in technical meeting from Lovech municipality

There are plans to build gas charging stations (near Slavyani for example) near the old pipeline, which could be between it and Nabucco. Response: Nabuco Bulgaria has nothing to do with these stations of private owners but their coordinates are a mandatory subject to clarification and consideration when planning.

87 Participant in technical meeting from Letnitsa municipality

Where does the pipeline enter in Bulgaria? Response: The pipeline enters Bulgaria near the village of Strandzha on the Bulgarian-Turkish border.

88 Participant in technical meeting from Letnitsa municipality

When is anticipated the construction of compressor stations? Is it possible not to build any? Where do you build such a station, administrative? What power will consume compressor station? Response: 1) It depends on the completion of the “open season”. 2) Its unlikely and depends on the estimates of the studies but its possible not to build a compressor station near the municipality. 3) Again depends on the technological requirements. 4) About 800 KW but will be used mainly gas from the pipeline.

89 Participant in technical meeting from Letnitsa municipality

At what depth will the pipeline be buried? Response: The depth of the trench is minimum 2,5m and the land cover above the pipeline is minimum 1m.

90 Participant in After covering the trench and the pipeline what will you do with the redundant soil? Will be

page 129 of 156

technical meeting from Letnitsa municipality

there laying of inert materials? Will there be a collapse of soil above the pipeline? Response: 1) Soil will be transported and disposed on specially designated areas. 2) With rock mass are laid 10-15cm backfilling and 10 cm ductile soil but at areas with regular soil (as at Letnitsa) there will be no backfilling – the same soil will be used and recultivation of the humus layer. 3) There will be no subsidence and collapsing because of the tamping- there might be a slight embankment over the pipeline which will subside quickly after plowing and rain.

91 Participant in technical meeting from Letnitsa municipality

How will the power lines be intersected? Response: Received data from NEC (for power lines with voltage 110, 220 and 400 KW) and investment companies (for power lines with voltage 20 KW) for all lines in the area of the pipeline route and are mapped. Depending on the ongoing electricity are applied various measures to ensure security of the power lines. The cables can’t be mapped but the posts are registered, due to lack of information from the investment companies, including BTC.

92 Participant in technical meeting from Letnitsa municipality

Are the places for storage of materials and the routes for the movement of the materials (and the heavy vehicles) defined? What is expected to be commitment of the municipality? Response: 1) Sites are needed for temporary construction camps, where worker are housed, as well as sites for storage yards- for preserving the materials. The designer is interested in renting such sites from the municipalities- uncultivated areas, former cooperatives and etc. which can serve as warehouses and camps. These sites are approved in the SPP (Spatial Parcel Plan) which must be approved by the competent authorities. CEZ (and other investment companies) should be able to react promptly and provide electricity to camps and warehouses, after approval of their location in the SPP. 2) The technique to be used is unique. Heavy tracks that will move will only be used for runway construction because the road surface cannot carry their load. Ahead is the making of detailed management plan for transport.

93 Participant in technical meeting from Letnitsa municipality

In the 400m easement zone probably falls a large number of facilities of CEZ.Response: There is no easement for 400m It is about 36m asymmetrically construction strip (12+26m from trench), the zone of 400m is the restriction of construction.

94 Representative of Chimcomplect

Are there some new objects on or around the project pipeline route? Response: CEZ- we recommend to connect with NEC about realised major project in 3 phases x 75 turbines, total 225 turbines in the agriculture area Miziya- there must be registered data. The park is quite large and may affect the planned route. NEC has the data about the large investment companies. For smaller wind farms we recommend to contact municipality services Agriculture which must have data on land use.

95 Participant in technical meeting from Byala municipality

It is good that in the municipality the gas pipeline follows the easement of the existing gas pipeline which contributes for the positive attitude to the Nabucco pipeline. Response: The easement of Nabucco does not fall within the easement area of the existing pipeline. The plan is the two pipelines to be positioned close to each other and to have separate easement areas but a common security zone.

96 Participant in Is there common to all countries transboundary environmental impact assessment?

page 130 of 156

technical meeting from Byala municipality

Response: Yes, this is the Espoo convention on Environmental Impact Assessment in a transboundary context. It is regulated by the national competent authority- MOEW.

97 Participant in technical meeting from Byala municipality

What part of the transported gas we will be able to use? Response: As one of the shareholders together with the other we participate for up to 50% of the amount of transported gas. Depending on the needs, each company may request access to the capacity of the supplies of Nabucco. As a potential the whole consumption of the country may be provided by Nabucco but that depends on the preferences of users and providers.

98 Participant in technical meeting from Byala municipality

In what period of time will be able to use this resource? Response: The concluded agreement and political support is for a period of 50 years but it is quite possible that this period will be extended.

99 Participant in technical meeting from Oryahovo municipality

What can the municipal council do for the Nabucco project? Can you provide a map of the project and the passing through the land? Do you think the municipal administration can contribute on the issue of people’s property? Response: 1) We rely on the assistance of the municipality in all matters of local importance and competence; 2) Map will be presented on the municipal information board, a P.O.box is installed as well for making post, comments and questions; 3)A SPP plan is prepared which will be accessible to all stakeholders.

100 Participant in technical meeting from Oryahovo municipality

The mayors will disseminate information on their settlementsResponse: Thank you for your involvement and we rely on active cooperation with local authorities.

101 Participant in technical meeting from Oryahovo municipality

Agriculture is major branch of the economy and the planned recultivation is

calming.

Response: That is right, this is an obligatory measure.

102 Participant in technical meeting from Oryahovo municipality

What plants could be sown?

Response: Only long standing and the owners will be compensated.

103 Participant in technical meeting from

If the pipeline route is changed will we be informed promptly?

Response: Within the DDP- preliminary project the entire route has been photographed and a

page 131 of 156

Oryahovo municipality

500m corridor prepared. In these 500m the route can vary and changes can be made. Of course these changes will be promptly announced.

104 Participant in technical meeting from Knezha municipality

Is there a mapped route of the pipeline on the territory of Knezha?

Response: Yes, part of the materials that we present to You in relation with the providing of information is also map material with the pipeline route. Forthcoming is the entering the route of DDP - preliminary plan, which will be coordinated.

105 Participant in technical meeting from Knezha municipality

We assume that valve stations will be built? We recommend ensuring their safety

and security.

Response: Of course. They will also be marked on the maps which will be provided to you. And for their safety maximum level of security will be ensured.

106 Participant in technical meeting from Iskar municipality

How can I find out where the route of the pipeline will pass?

Response: The municipalities are provided with maps of the pipeline route.

107 Participant in technical meeting from Iskar municipality

When are the DDP expected to be ready?

Response: By the end of the year.

108 Participant in technical meeting from Iskar municipality

People are interested in the issue of compensation for their lands.

Response: The owners through whose land the pipeline passes will be compensated for the period of construction and after completion of construction the land will be recultivated and used again by the owner with easement restrictions.

109 Participant in technical meeting from Iskar municipality

Can local workers be used for construction of the pipeline?

Response: Specialised equipment will be used for the construction which requires specific qualifications. But there will be a non-specialised activities as drivers, guards etc. which can be implemented by local residents. This possibility has been considered when the ESIA report was prepared as a measure to mitigate any negative impact and to encourage the local economy. On the other hand we rely on the mayors to provide information about the possibility of building a temporary construction camps and storage sites that you can send to Chimcomplect.

110 Participant in technical meeting from Iskar

When will the construction work take place?

Response: The construction will be performed in the period 2012-2015 and after the approval of the schedules they will be presented to municipalities and authorities.

municipality

111 Participant in technical meeting from Iskar municipality

Are any compensations provided for the 400m security zone?

Response: The law requires the presence of such a zone and there are no compensations for it.

112 Participant in technical meeting from Iskar municipality

When the property is not divided how will the legatees be compensated, taking into

account that there are some that live abroad? And what is the role of tenants?

Response: Because the project was declared of national importance we rely on cooperation with local authorities to solve this and other problems.

113 Participant in technical meeting from Bolyarovo municipality

What is planned to provide an emergency safety?

Response: Very high safety level of the equipment is planned according to high standards and safety requirements with continuous monitoring.

114 Participant in technical meeting from Bolyarovo municipality

Isn’t the distance between the block valves too big (20-30km) we recommend that

you visit the site of a recent accident with caused damage in diameter 300m

Response: Taking into account the recent accident near the settlement the apprehensions of the representatives of the community are understandable. The European community however, has very high demands on safety and those requirements were transposed in the Bulgarian legislation. In the design process are taken maximal security measures.

115 Participant in technical meeting from Bolyarovo municipality

The cluster of construction equipment and machines leads to trampling and soil

pollution and creates worries among the population.

Response: In order to recover the areas in their previous condition additional resources will be provided and included in the budget. The actual restoration of the environment is a term taken into consideration in the planning of the project and in the ESIA report.

116 Participant in technical meeting from Bolyarovo municipality

A serious problem will be the damage to road infrastructure.

Response: The ambition of the designers is the Nabucco project to set standards for future projects with its measures to restore the used infrastructure. The draft ESIA report includes various measures including restoration of road infrastructure due to damage caused by the project.

117 Participant in technical meeting from Bolyarovo

Are any funds for the local community foreseen, for instance for community

centres?

page 133 of 156

municipality Response: As the project is international it does not have a purpose to stimulate the local community. The opportunity for financing the local community as a mitigation measure will be discussed and the outcome of the discussion will be brought to the attention of the local administration.

118 Participant in technical meeting from Bolyarovo municipality

Will there remain wastes and obsolete equipment around the trenches after

construction? We ask this question because we had such problems with the construction

of previous projects in the municipality.

Response: No, all the wastes will be transported and processed. This is part of the project planning.

119 Participant in technical meeting from Bolyarovo municipality

Will you hire local workers?

Response: Specialised equipment will be used for the construction which requires specific qualifications. So the use of local work force will be limited, with the exception of the demand for non-specialised workers. Separately at an interval of 25km will be sites for accommodation of the workers and for storage of the pipes. Basically there will be two central warehouses- in Sliven and Pleven, where 6800 pipes will be stored.

120 Participant in technical meeting from Bolyarovo municipality

How far will be the Nabucco pipeline from the existing gas pipeline and on which

side?

Response: On recommendation of the designer Penspen the new pipeline will be located 100m away from the existing pipeline- when entering Bulgaria is on the right and at Lozenets passes left of the existing pipeline.

121 Participant in technical meeting from Bolyarovo municipality

Will there be delivery/acceptance protocol for the performance of the reinstatement

activities in the construction strip? Will there be delivery and acceptance for the issue of

land in the form in which they were works?

Response: Yes, the project will be seeking cooperation and signature from representatives of local authorities and the settlements for acceptance of the land after the construction.

122 Participant in technical meeting from Bolyarovo municipality

Where will be a compressor station built, if such will be built in the municipality?

Response: On latest information one compressor station is expected to be built in municipality Omurtag and one in municipality Oryahovo. These locations however can be changed and are not considered as definitive.

123 Participant in technical meeting from Bolyarovo

Currently we don’t have a map with precise coordinates therefore we can not give

correct data. For us it is important to understand where exactly the route passes, where

will be the sites for workers and pipes, the temporary roads etc. Also the water and

page 134 of 156

municipality electricity supply. In short it is important to know what damage we can expect.

Response: A DDP-preliminary and DDP- final project is worked out, as currently we are at the stage of preliminary draft. Municipalities will participate in the coordination of these plans. Indeed the pipeline route is shifted by 100m from the existing security zone and it is not expected to significantly affect the existing infrastructure or planned investment proposals.

124 Participant in technical meeting from Bolyarovo municipality

We want it to be specified what would be the benefits for the population from the

realization of the project

Response: Thank you for this question which will be carefully discussed

125 Participant in technical meeting from Bolyarovo municipality

What is the necessary power for the facilities – valve stations and so on, as the existing power is not high?Response: Up to 1 kilowatt for the valve stations. Near Losenets it will be built Gas Measuring Station, which power consumption will not be more that 50 to 100 kilowatts. Compressor station, in comparison, needs around 800 – 1000 kilowatts.

126 Participant in technical meeting from Bolyarovo municipality

We understand that the only thing that will be done is to recover the construction’s consequences. We want to tell us clearly that the local community will gain nothing for the project.Response: We must not forget that Nabucco is international project that has international and national significance and in smaller extend – local significance. It’s purpose is clearly expressed during meeting as the meeting today

127 Participant in technical meeting from Sredets municipality

It is not clear what is the security of the gaspipeline and what are the measures in case of emergency situations. It is recommended during community meetings to explain what the safety of the facility is. It is not cleared what is the distance from the existing pipeline. In what state it gas is transported – liquidity or gaseous? 20 – 30 km is seen as too big distance for the valve stations – it is recommended to be constructed also manual valve stations. In what way the control over the pipeline’s work will be realized.Response: Unfortunately gaspipeline’s troubles are a fact, but on a yearly basis it’s a very small percent that is constantly reducing. During design phase the materials as well as the work are under the control of very high European and international safety standards. The gas is transported in gaseous state, because transporting in liquid state requires supporting of permanent temperature of 169°С. As regards to safety, on central level fire department delegated preparation of there measures to the designer, and subsequently discussion of these measurement will be conducted. The minimum distance recommended between two gaspipelines is 35 m, but in order to avoid damages on existing pipelines during construction, including detonate activity, this distance is increased to 100 m. On the territory of Yambol and Burgas municipality are not planned construction of compressor stations, but at this moment the route is still under specification. Permanent monitoring and control of the facilities is provided. Emergency plans and groups for emergency reactions will be created. Briefly Nabucco gaspipeline provides

page 135 of 156

unprecedented for Bulgaria safety measures – permanent video monitoring and remote control.128 Participant in

technical meeting from Sredets municipality

What are the benefits of the local community from realizing the project?Response: The aim of this international project is not developing the local community, the project has international and national dimension. Subject of the impacts on the social environment study is the way by which the project could engage local work force, local suppliers of goods and services and to connect pipeline’s construction with potential possibilities for the local communities. But we have to underline that this analysis and measures are prepared as a part of an investment business project, which social impact is not of primary significance.

129 Participant in technical meeting from Sredets municipality

Is the ESIA for Bulgaria a separate report, is there any ESIA report common for the 5 countries?Response: ESIA report for Bulgaria is separate document, at the end a common document for the 5 countries crossed by the gaspipeline will be prepared.

130 Participant in technical meeting from Sredets municipality

What timeframes has the construction phase? It is important for the Natura zones.Response: Construction is fully conformed to circumstances and conditions on the places. The construction itself is expected to continue year and a half – two years. On municipality base it has to finish for several months along with the landowner’s compensations. Construction is conformed to the periods when animal species and their habitats will not be disturbed.

131 Participant in technical meeting from Sredets municipality

Recommendation of the mayor prior to the meeting opening: careful recultivation and cleaning of the construction strip from wastes and materials after the end of construction. This was pointed out also in Bolyarovo municipality, where this problem was indicated as sensitive for the local authorities, respectively for the local community.Response: The recommendation and the identified sensitive question are going to be taken into consideration.

132 Participant in technical meeting from Straldzha municipality

How the landowners will be compensated. After the end of the repair works on the gas pipeline there are ruts and unrecovered pedestrian terrains – do you consider this as important. I see that you’ve tried to avoid Natura 2000 sites, but there are some places, where you didn’t manage to do it – how you are going to work there. Construction strip – what kind of activities are you going to do there – I suppose that compensation for the landowner will be noted, as the use is limited in respect to perennial crops and so on?Response: Landowners, whose lands are crosses by the Nabucco route, will be compensated based on market prises. Compensation themselves are conformed to different factors – not only land’s prise, but also sown crops, Voynishki Bakardjik is Natura 2000 zone. For its avoiding a few kilometres were added to the pipeline’s route. Protection of the protected zones is respected in maximum possible extend during design phase. Nature zones with protected status are different and these are not only Natura 2000 zones. I order to realize the project, many baseline studies are made, aiming to be conformed to the project. For the gaspipeline the consequences will not be serous, because the object is buried and do not divide land or fragmentation of the protected zones.

133 Participant in On the territory of the municipality, in the scope of the planned route of the gaspipeline there are

page 136 of 156

technical meeting from Straldza municipality

existing Water supply systems – what you are going to do with them? Response: Data for the existing infrastructural objects and facilities are collected from the respective companies, regulatory authority and investment companies – for Water supply systems as well as for the electricity networks. In case of infrastructure’s affection emergency repair works are made and affected parts are compensated. All this is an object of strict procedure.

134 Participant in technical meeting from Straldza municipality

There are possibility construction terms of Nabucco to coincide with the construction of the highway – this could highly limit moving into the zone of its construction.Response: Construction of the two objects is not going to coincide. If the highway is constructed first one, a sort of mantle will be made and the gaspipeline will be put through. And if the gaspipeline is constructed first, this will not affect the highway construction.

135 Participant in technical meeting from Straldza municipality

What exactly is going to be done in the 500 meter corridor – what activities and restriction are planned for this zone?Response: These 500 m. are a sort of “virtual” zone that do not concern any reglamentation or systematisation and is made for use by the designer. This zone is designated for design’s comfort – in case of construction of wind farms and other projects or restrictions, the designer could plan rerouting in the 500-meter zone. In some cases the designer is obliged to come out of the zone. At the moment the additional shooting and studies.

136 Participant in technical meeting from Straldza municipality

Mayor’s questionnaires – require much time and information – we want if it is possible representative of the company that develops ESIA to visit the mayors and to explain and help the mayors to fill the questionnaire.Response: This recommendation has been noted in the minute of the meeting.

137 Participant in technical meeting from Straldza municipality

Municipality land fund – Much of the lands are ceded for management to private persons, which rely on subsidies. What is expected in such cases, when the route passes through such lands? The question is very serious, as the infringement of the landowner’s obligations is followed by very serious fines and termination of the subsidies.Response: Following these meetings and this question, it was sent a letter to the Ministry of Agriculture and in the beginning of October we expect a meeting with the Minister of Agriculture and Food to clarify this question. Thank you very much for this note. Nabucco Bulgaria regard to this question very serious and we are going to ensure information and cooperation procedure with such landowners.

138 Participant in technical meeting from Straldza municipality

On the existing gaspipeline’s route recultivation was not made and consequently these lands were excluded from subsidies. This is a serous restriction for the landowners and creates negative attitudes among people.Response: We suppose that such approach – meetings and consultations also was not applied on previous gaspipeline projects. These measures continue after the construction. We are obliged to represent detailed plan in front of financial institutions for communication, consolation and discussion; for clear representation of the activities and expected consequences for the settlements and their citizens. It is determined also a strict procedure for communication between

page 137 of 156

stakeholders and investor after the construction as well. The land recultivation itself is connected with establishment of expert commission with the participation of municipality and mayors of the settlements to observe the recultivation and recovery of the land. Very severe measures are taken for land restoration – recultivation, a slight shaft that is going to flatten with the first rains or plowing and so on.

139 Participant in technical meeting from Straldza municipality

During the past gaspipeline construction rocks were piled on a private land, later this land was drained without owner’s agreement and knowledge. How such situations are going to be avoided during construction of Nabucco?Response: Intern and dug material will be deposed only with the knowledge of the mayor and with his order. That is why we rely on cooperation with local mayors to avoid all types of unwanted from the two side’s activities. With regard to what happened here, it is a responsibility to the local authorities to require compensation.

140 Participant in technical meeting from Straldza municipality

Plan for traffic organization during construction – when and how we are going to have such? How the roads are going to be recovered and it is possible municipality roads which now are in bad condition to be also recovered? Response: Aiming studding of the consequences of the construction on the traffic network, a full set of data is analysed - road network condition and existing traffic, to which the planned construction activities are relevant. The capacity of the roads to take the traffic, as well as the possibility for creating temporary roads for access to the construction strip are estimated and measures for recovering of the damaged roads are planned. For Nabucco gaspipeline, in order to protect roads, bridges and so on, it is planned transport of only one pipe at the same time. For comparison, until now the practice was to transport two or three pipes at the same time.

141 Participant in technical meeting from Straldza municipality

River Marash is situated in the south part of the complex Straldza next to village Atolovo. We are worried that changes round the river and dikes, connected to the construction could lead to floods.Response: All planned measures will be presented to the local authorities and to the relevant experts. Their opinion is very important for avoiding of such dangers.

142 Participant in technical meeting from Straldza municipality

13 September – accident. It is recommended valve stations to be located on comfortable and short distances.Response: As a whole valve station are located on each 20 – 25 km. But we can declare that during Nabucco construction very severe and unprecedented safety and security measures will be observed during construction and operation of the facility. For the first time in Bulgaria SCADA system will be applied by optical cabel. By this system the whole gaspipeline route is monitored and controlled 24 hours a day from distance. On the places with valve stations is planned video monitoring in order to avoid not only accidents, but also intentional malicious acts.

143 Participant in technical meeting from Straldza municipality

Nabucco is a national project, what would happen are few landowners declaring that they refuse to give their lands?Response: Project status and national legislation exclude the question if the gaspipeline is going to cross their lands or not, but what compensation they are going to receive. The right of way itself comes only after compensation payment.

page 138 of 156

144 Participant in technical meeting from Sungurlare municipality

On a minimum depth of 1 m, the agricultural activities may be affected, for example deep plowing on 70 – 80 sm. depth?Response: 1 m. is the minimum distance from the upper side of the pipe to the surface. As a whole the expected distance is 1,2 – 1,3 m. As a respect to the risks of reaching the pipe, from 70’s till now there is no such case with the existing gaspipelines that measures to 2600 km. and are located mainly in agricultural lands.

145 Participant in technical meeting from Sungurlare municipality

We doubt that it is necessary to be organized discussions with the local population as people could disagree gaspipeline’s crossing through their lands.Response: Of course it is necessary to be organized such meetings. Citizens must be and they will be informed. Also they will have the possibility to direct their recommendations and questions to us anytime.

146 Participant in technical meeting from Sungurlare municipality

People are interested what the benefits are for them personally. It is recommended money to be given for ennoblement of the settlements.Response: The project is very big and it is impossible to make note for each one person. The note is made on the base of regions. The project is conformed also with the possibilities of stimulation of the local economy – work force, suppliers of goods and services, areas for worker’s camps and construction materials yards.

147 Participant in technical meeting from Sungurlare municipality

When in Novo selo was built US military camp, they asked the local people what to do for them, to invest in the settlement.Response: The projects themselves are from different type – the first case supposes permanent settlement and presence, and the second – construction of underground facility with minimum impact on the settlements after the construction phase.

148 Participant in technical meeting from Sungurlare municipality

How exactly the social assessment will be made – there were cases when vineyards’ prises were increased or decreased? How the construction strip will be recovered and how are going to be avoided malicious activities from the part of the workers – for example a worker could take a shortcut through crops?Response: In respect to the compensation procedure – clearly and openly we point out our contacts and we seek conversation with all stakeholders. Landowners will be compensated based on market prises once for the time of the construction and second time for the right of way. Compensation depends on the cultivated crops. All landowners will be compensated, as this a necessary condition for entering into forces the right of way. The possibilities for communication for us are also many – not only for the local authority, but also for the citizens. In respect to the recultivation – all roads and measures are marked in the project. Fencing of the construction strip restricts also the possibility malicious workers to take short cuts through agricultural lands with heavy machinery. We’re establishing a communication register for stakeholders, including as regards to recultivation. In a face to face conversation after the meeting was explained the difference between evaluation of agricultural lands and social impact assessment – difference in essence, scale and aims of the two studies.

149 Participant in What is the coefficient of protection of the system and what are the safety measures?

page 139 of 156

technical meeting from Sungurlare municipality

Response: Gaspipeline is tested on 140 atmospheres, and pipes have also internal anti-corrosion coating. The so called SCADA system will be integrated for permanent monitoring and control of the facility.

150 Participant in technical meeting from Sungurlare municipality

Is there any attempts and simulations for emergency action made for example in a case of system crash?Response: It is not a coincidence that the route is projected on a significant distance from the urbanised zones. From the other hand, the methane is light and is dispersing in the air, even if one valve station do not function, the next one will be used. The high standards for safety and security are a basis for high confidence in gaspipeline’s safety.

151 Participant in technical meeting from Sungurlare municipality

Are there any staffs on the stations for increasing the pressure?Response: The station near by will be remote-controlled.

152 Participant in technical meeting from Targovishte municipality

The compensation that landowners are going to receive will be for the time of construction, I suppose? Is it planned compensation for municipality lands – pastures, lands and so on?Response: Compensation does not concern only use of the land during construction, but also restriction for the owners form the right of way. This restriction will be also calculated in the compensations that will be defined on market prises. The market prises are an object if procedure and study. We rely on the cooperation of the municipality during preparation of the land assessment. This is a request from our part of course. Compensation is owed regardless land ownership, and is affected by the cultivated crops and other objective factors.

153 Participant in technical meeting from Targovishte municipality

During the third quarter (vacation’s period) of 2012 the procedures for right of way and right of construction are going to be underway. Given the hard procedure it is recommended the documents to be provided on a maximum early stage in order not to slower the procedure.Response: We’ve planned in the end of this year to have already identified the gaspipeline route and to give way to the formal procedure. We’ve planned a period of three months for finishing of the formal procedures connected to the land ownership. Specification from a municipality employee: There are statutory periods, but the recommendation of the deputy mayor is the documents to be presented as soon as possible in order not to slower the formal procedures. Response: Of course, our desire is to cooperate effectively and our request is to work in a maximum short terms where it is possible to avoid delay.

154 Participant in technical meeting from Targovishte municipality

This 25 km that pass through the municipality – we suppose that they are going to be occupied during the whole construction period, you’ve mentioned two years?Response: On this early stage, the construction and land occupation is a question of specifying. This concerns also sites for construction camps and site for storing the materials. But we can affirm that the municipalities will be crossed in up to one season in order not to have open trench on the territory of the whole country.

155 Participant in Who is going to give the building right?

page 140 of 156

technical meeting from Targovishte municipality

Response: It is issued by the Minister – one building permission for the whole project.

156 Participant in technical meeting from Targovishte municipality

What is the significance of this project for the population on a local basis, because we expect that it is going to have supporters as well as opponents of the project and it would be nice if we can tell more concrete things to support the project, to ensure bigger support among the population?Response: This is one of the purposes of the social study – to collect detailed information about how the project could benefit the local communities and how we can avoid adverse impact. Building of constructions camps and sites will contribute with rents and supplies for the local community. Of course all depends on the local conditions and possibilities.

157 Participant in technical meeting from Targovishte municipality

Population is interested in the social part – what is going to win and what is going to lose. Are the places, roads on which heavy trucks pass going to be recovered? There are people that say: “What you have now, you’ll lose it later”.Response: That is why we undertake such meetings and we inform the community and stakeholders – to know what is going to pass here. It is not possible to avoid adverse impacts, but we will fully recover affected lands and roads, at least in their initial condition. We are available for all types of questions and commentaries during all the time and we are going to be responsive to all stakeholders. We are going to inform the population in details soon – brochures, Internet site for those who use Internet, public discussions will be held. To avoid the possibility to gamble with people’s opinion we first of all undertake series of such informative meetings and create information corners, that were mentioned during presentation. During the sociological study we hope to understand informative assessment and citizen’s attitude. One plus for the advantage of being informed – in Sungurlare the mayor asked how a strip of 500 m will be dig and how the people’s land will be expropriated – as you can see such thing do not exist.

158 Participant in technical meeting from Varbitsa municipality

This meeting and the materials are very useful for all of us in getting known with the project. You said that it is being prepared preliminary and final DDP – do you know when they are going to be ready, as the landowners who do not live in Varbitsa have to be informed. Are there some stations – compressor, control or measuring – that are going to be built, is this related with new work places? In respect to the new temporary roads – is their location at maps final? And a little bit funny question – what is the history of the name Nabucco?Response: DDP are presented for coordination to all municipalities and we hope that soon they will be cleared. In respect of the landowners a procedure for their identifying is underway aiming payment of compensations for gaspipeline’s crossing through their lands. This procedure is a necessary condition for receiving building permission. On this stage it is not planned building of compressor station in the municipality, but we expect technical parameters on which base the locations of the stations will be defined. Until now it is defined orientation, preliminary location next to Omurtag, between Beloslavtsi, Tapchileshtovo and Prezviter Cosma, but as soon as the location is finally defined, the information will be presented to the municipalities. In respect to the works force hiring – the subject of the social study is the possibility for local development, including hiring of local work force, which will be engaged during construction period, and the

page 141 of 156

more qualified it is, the better. In respect of the roads, the project is coordinated wit Traffic Police and Ministry of Transport, Information Technology and Communication and conformed to local conditions. To avoid in maximum stage the infringement of the road network and the bridge facilities only one pipe will be transported on one run, instead of two or three pipes on a run. In a respect to the temporary roads, they are going to be careful planned, and they are going to be the least possible. Mainly the transport is going to be made in the construction strip. The designers if all the countries gave the name “Nabucco” by the name of the opera which they had visited the previous night. The libretto of the opera itself wasn’t a coincidence as well – Nabucco tells about the meeting between East and West and the gaspipeline Nabucco is such energy meeting.

159 Participant in technical meeting from Varbitsa municipality

There is conversation for construction of the road I-7 (Silistra-Varbitsa-to Greek border-Lesovo) and if the two projects coincide, this could affect the available local work force.Response: The two projects will be conformed and we do not expect their realization to create conflicts or the work force to be insufficient.

160 Participant in technical meeting from Varbitsa municipality

We are not the first municipality where such meeting take place. Are there any indications for rerouting or for negative attude towards the project in any municipality?Response: We have already made more than 10 meetings in municipalities and we do not have such cases. On the contrary, everywhere we are facing acceptance of the aims and necessity of the project realisation.

161 Participant in technical meeting from Varbitsa municipality

Again for road I-7 – are the two projects conformed?Response: There are no way the two projects to exclude one another and realization of the one of them to damage the other. And without coordination of the project there is no way the project to receive building permition.

162 Participant in technical meeting from Varbitsa municipality

Question towards Mr. Donchev: do you mean that the municipality is located in a seismic zone and that a few years ago it was an epicenter of earthquake with magnitude around 3,5 on the Richter scale?Response: Risk assessment as this one made for Nabucco, hasn’t been made until now. Nabucco passes through 10 seismic zones, that are fully known and studies by BAS. Future fault’s activity and material’s reliability are carefully analysed and conformed.

163 Participant in technical meeting from Varbitsa municipality

How much exactly is more reliable Nabucco than gaspipelines built until now? Recently there was a detonation, accident near village Gorska Polyana?Response: The mention accident is the first one since 30 years and there is no precedent. In respect of Nabucco, the European requirements for the project are so severe and strict that, without saying a concrete coefficient that would be adjustable, I surely claim that the planned gaspipeline is many times safer than the existing pipelines. Fortunately the accident hadn’t serous consequences and the affected zone, that is insignificant in comparison with the damages after harvest for example although the ban for lighting the stubble. During the accident itself, the valve station has worked at time and the situation has been under control. It is planned, for first

page 142 of 156

time in Bulgaria, to be integrated the technology SCADA for permanent monitoring and remote control on the facility. The measures for testing the safety of the facility prior to operation and the measures for support, made to each 8 years are also very severe and tested.

164 Participant in technical meeting from Varbitsa municipality

Ticha Dam is managed by Irrigation Systems- Shoumen and it is the main water source for two municipalities. The sanitary protection zone of the dam is an object of regulation, but since now there is no such zone although the dam is a source of potable water. And according to the legislation building of pipelines for oil and other toxic products is forbidden in such zones. On approval of such zone the gaspipeline will be in conflict with the law.Response: European legislation excludes every unacceptable environmental risk. The question for coincidence with third zone of Tucha dam, which in not cleared, is going to be resolved together with the municipality. This is valid for building permission as well as for the funding of the project. Gaspipeline is fully consistent with the normative base and real position of the place. The regulation is about oil and toxic products – if’s an object of specifying is the gas is a part of this list – the gas is light and it disperse in the air. The system is completely hermetic and if there are disorders they are immediately detected and eliminated.

165 Participant in technical meeting from Varbitsa municipality

What does it mean third sanitary protected zone of the dam?Response: Second zone is up to 500 m and then it’s third zone (note by municipality employee). The gaspipeline is on 1,5 km from the dam and is designed at the biggest possible distance from it and from town of Varbitsa.

166 Participant in technical meeting from Varbitsa municipality

We want at the moment of the meeting to be officially noted that the municipality want the route to be moved with 850 – 900 m north, as we are planning in future construction of collector and differentiation of industrial zone, because territorially the town could develop itself only in northern direction.Response: Your wish will be noted, but we want to receive by the municipality concrete dimensions of the recommended rerouting, as the change of the route is connected with serious design work. There was similar question in Sungurlare municipality, but on concrete clarification of the restrictions we realized that the gaspipeline do not interfere the municipality’s plans. And we want to dispute this on the basis of concrete intentions and DDP plans.

167 Participant in technical meeting from Varbitsa municipality

You’ve mentioned that there will be another one meeting, when it will be held?Response: There will be not one, but many meetings as a part of the procedure for communication and cooperation. Moreover there are many ways to connect with us – informational corner, address and e-mail, phones. You can turn directly to Vienna as well.

168 Participant in technical meeting from Varbitsa municipality

Is it planned a gasification of Varbitsa and local villages or it’s just a transit gaspipeline?Response: Gaspipeline Nabucco has only one point of connection to the national gaspipeline supplying system. Maybe it would be economically more practically municipality to connect itself with the national gaspipeline system and not to build facilities in the municipalities and regions.

page 143 of 156

169 Participant in technical meeting from Antonovo municipality

Is the DDP already done? We’re asking because it is necessary to inform all landowners, some of them are abroad.Response: It has been made DDP – preliminary project, soon the final project will be done. We’re preparing procedure for identification of all landowners and their information. We count on support from the local authorities on this point.

170 Participant in technical meeting from Antonovo municipality

It was explained that during construction there will be fences around the construction strip – is this concern also the roads?Response: No, it doesn’t, the roads will be completely accessible and the traffic will not be restricted.

171 Participant in technical meeting from Antonovo municipality

Which one Natura 2000 zones he first one variant of the route crossed? I’m interested particularly if there are zones affected next to Popovo.Response: According to the first one plans we passes for example through the Kotlenski Balkan and zones for recreation. Close to Popovo we pass through reserve Orlitsa. On establishing the Natura 2000 zones and other protected zones, these corrections were made.

172 Participant in technical meeting from Antonovo municipality

Is it expected the terms for the construction to be respected?Response: This is our wish.

173 Participant in technical meeting from Antonovo municipality

Is there any ground facilities on the municipal territory except of the linear part?Response: It is possible to have one valve station on a site with dimensions around 30-40 m.

174 Participant in technical meeting from Antonovo municipality

Can we expect problems with the livestock owners due to the restriction connected to the fences?Response: It’s an object of study and additional information to learn which places have to be ensured so the livestock to pass without problems without restriction of the it’s move.

175 Participant in technical meeting from Antonovo municipality

How long will the construction continue?Response: Our aim is to pass maximum fast and the construction cycle to be closed. It is planned the construction to be made in section of around 50 km. At least it is not profitable for us to support a long channel.

176 Participant in technical meeting from

What about the underground cadastre?Response: At the moment in DDP are laid down all communication to all stakeholders - plumbing, electricity lines, optical cable and others, located in the 500 m corridor. In case of

page 144 of 156

Antonovo municipality

damages and accidents, something that we’re trying to evade, we will repair and pay compensations for the damages.

177 Participant in technical meeting from Pleven municipality

Is there some information for the sites around the track? Response: A ground site object is expected- interconnection with the national gas grid- to have in Lozenets. There are also foreseen two alternative sites which will be submitted for approval in the Ministry of Regional Development and Public Works. Beside them there will be sites for the valve stations at intervals of 20-25km. Studies for positioning of two compressor stations on the territory of municipality Omurtag and Oryahovo are made.

178 Participant in technical meeting from Pleven municipality

Is there more information about the sites for disposal and storage of pipes and construction materials? Response: We would like to have more of these sites. The main designer recommends planning two sites- in the municipalities Sliven and Pleven with size about 150-200 acres for the deployment of 6800 pipes and other materials. Contacts are established with Plama Pleven and Ministry of Defence but for now we don’t have concrete proposals. Dimitar Donchev comment from RIEW: You have oriented right and we endorse the use of existing infrastructure instead of changing the status of agricultural land, etc.

179 Participant in technical meeting from Dolna Mitropoliya municipality

The presentation was very interesting but the presented several months ago DDP couldn’t help us to identify the properties and their respective owners. This is a very delicate issue and until it is cleared we can not fully evaluate what will be the impact on the settlements. Response: We follow strictly the procedure and maps are actually a large scale. For the purpose of the design is used and analysed 500m corridor. When the DDP is finalised it will be duly submitted to the municipalities and citizens of the settlements. Response by municipal employees: We are interested in particular whose are the properties, which are going to be passed during construction.

180 Participant in technical meeting from Dolna Mitropoliya municipality

The data for the inquiry were taken mainly from official sources and the mayor basically. Response: Indeed we expect to obtain accurate data exactly for settlement and municipality level.

181 Participant in technical meeting from Dolna Mitropoliya municipality

Roads, internet, communications- these are spheres which if are reinstated will be assessed very positively. The communications are mainly through mobile phones, also it can increase the employment of labour.Response: We observe carefully these reasons and they will be considered.

182 Participant in technical meeting from Dolna

We will send information as well for protected areas if needed. Response: We already have information and the protected areas are avoided in the design.

183 Participant in technical meeting from Dolna Mitropoliya municipality

Most of the land is cultivated by tenants, which will be compensated then? Response: This is a matter to be carefully studied and the results will be brought to the attention of stakeholders.

184 Participant in technical meeting from Dolna Mitropoliya municipality

I’m not mislead that there might be some greater effect for the population. In our municipality only the village of Gostilya is affected. We will assist completely in the further work. Hopefully local workers will be hired, I guess that is a subject of analysis. Response: We appreciate your cooperation.

185 Deputy Mayor of Pvlikeni Municipality

Pipeline’s route will be fenced. Is this fence staying only during the construction?

Response: Yes, the fence will be present only during the construction.

186 Deputy Mayor of Pvlikeni Municipality

Are the municipality routes going to be reorganized during the construction?

Response: All the reorganization of the route infrastructure will be coordinated with the local authorities.

187 Deputy Mayor of Pvlikeni Municipality

What about 3rd class routes (dirt roads) used by agricultural machinery?

Response: Special roads will be created to enable agricultural machinery to pass through the construction strip. Special roads will be created for the livestock as well.

188 Participant in technical meeting from Pavlikeni municipality

I heard that agricultural land will be taken by the individuals through sales?

Response: The gaspipeline is buried, this means that workers would pass through the borders of the land only during the construction. The landowners will be compensated and the land will be recovered. If there is damaged production, it will be 100% paid. After the construction the land will be again agricultural. Only the land for above ground facilities will be bought, but this concerns just Lozenets village. In each 20-30 km along the pipeline’s route will be located valve stations in area of 30-40 m. This land will be bought on market prises. The exact location of these parcels is not defined yet. This will be done by the DDP – Parcel plan.

189 Deputy mayor of Pavlikeni municipality

Is there any other restriction in the easement area except of cultivation of perennials?

Response: Any construction will be forbidden, as well as hunting, fire, shooting. No building is allowed. All other agricultural activities are allowed.

190 Participant in Who will be responsible to monitor against violations?

page 146 of 156

technical meeting from Pavlikeni municipality

Response: Only the owner of the facility. With coming into force of DDP – Parcel plan, the owner has the right of easer line. It will be in his own interest to monitor against violations. It will be the same situation as with Bulgartransgas. The network’s operator monitors for violations and for troubles and ensures security.

191 Participant in technical meeting from Pavlikeni municipality

What if an owner doesn’t want the pipeline to cross his land?

Response: Such possibility exists. It concerns not only the gaspipeline, but all types of infrastructural projects. If there is such case, the procedure according Law on Spatial is followed. According the Energy Law, Nabucco is a project of national significance, therefore owners will be forced to allow pipeline’s crossing. Certainly, this will be done without infringement of their rights.

192 Deputy mayor of Pavlikeni municipality

Construction has to start in 2012, when it will finish?

Response: In 2015.

193 Deputy mayor of Pavlikeni municipality

What will happen with the piles of soil, dug during the construction? Where the unnecessary soil will be disposed? Is this going to be coordinated with the municipality?

Response: The terrain will be recovered. The diameter of the pipe is big enough, so a part of the dug soil will remain. The practice is: a shaft remains after the infilling of the trench, but with the time it flattens. The useless soil that could not be unfilled will be disposed on places, defined by the municipality.

194 Deputy mayor of Pavlikeni municipality

There will be 50 000 m³ of soil remained. Who will pay for the disposing?

Response: Certainly the investor. This point will be described in the project.

195 Participant in technical meeting from Pavlikeni municipality

There are many unemployed in the municipality. Is it possible part of them to be employed, as unqualified personnel?

Response: Having in mind the extremely specific activity, the EPC contractor will hire specialists. But we hope that during the two years of construction local people would be hired for services.

196 Participant in technical meeting from Gorna Oryahovitsa municipality

Gaspipeline’s route passes next to the route of the existing pipeline?

Response: Yes, it is.

197 Deputy mayor of Gorna Oryahovitsa

There will be harvest compensations just for one season?

Response: Yes. By the end of the year the DDP – Pracel plan will be done. There will be inserted

page 147 of 156

municipality all details about the landowners and they will be compensated. If there are tenants, then the tenants will be compensated. Is it possible in the area of the municipality to be built one valve station? This means that around 35-40 m² will be bought.

198 Deputy mayor of Gorna Oryahovitsa municipality

Is it possible new jobs related to the valve station to be created?

Response: Not exactly. But we hope that during construction there will have such possibility.

199 Deputy mayor of Gorna Oryahovitsa municipality

When construction is going to start and to finish?

Response: It is going to start in 2012 and finish in 2015.

200 Ecologist of Strajitsa municipality

We are aware of the project, we have worked with ESIA, and we are ready to cooperate with the project’s team.

Response: The project is of national significance, but on a local level we are concerned not to disturbed the population if it is possible, to create good jobs, but this would be possible only with the support of the local authorities.

201 Participant in technical meeting from Omurtag municipality

What will be the benefit for the local population?

Response: In this stage we can say that it is sure the project will contribute is short- and long-term plan. This is the purpose of the social study – to define specifics of the local live and to propose measures to mitigate the adverse impacts and to discover how to contribute to the region. During construction we expect that local work force will be hired. The social study will show us what is the condition of this work force, what is the rate of unemployed, the rate of the qualification.

202 Participant in technical meeting from Omurtag municipality

What are the long-term benefits for the municipality?

Response: It is not defined yet what exactly will be the scope of the needed services. Mainly the above ground facilities will be serviced. This will be defined later. If there are specialists here, then there is a possibility for a long-term job. I con not answer this question, it is an object of the social study.

203 Participant in technical meeting from Omurtag municipality

Can we use the gas from the pipeline?

Response: Gasification along the pipeline’s route is not planned. The gaspipeline is mainly transit. The gaspipeline is under high pressure, so it would be too expensive to be built local branches. At this stage there is one branch planned – close to Lozenets village that will connect the gaspipeline to the local gaspipeline network. By this branch the gaspipeline will be connected indirectly with the population, but directly – not. But the biggest part of the gaspipeline is lying next to the existing pipeline.

204 Participant in So, after the construction phase there are no benefits for us at all?

page 148 of 156

technical meeting from Omurtag municipality

Response: It is not sure. It’s a project of national significance, this means that it could impact in a short-term, as well as in a long-term. Social study will show us what type of specialist you have here.

205 Participant in technical meeting from Omurtag municipality

What will Bulgaria receive?

Response: Bulgaria has 16,7% - absolutely equal rights as the other countries – participants.

205 Participant in technical meeting from Omurtag municipality

Half of the gaspipeline’s route in the area of our municipality crosses irrigation field. Are you aware of this?

Response: Yes, all problem communications are under review. They are coordinated with Irrigation Systems, Basin Directorates. The place will remain agricultural, we are going just to pass under it. There will have no change, except of the restriction of orchards. It’s your place and you can do what you want with it.

206 Representative of Overgas Nord

Is the project consistent with the main pipeline? We are not informed. Do you have any information about our infrastructure elements?

Response: We still do not have such information, but we have conformed the route to the existing infrastructure. The aim of this meeting is to share any general considerations, if you have such. To all the municipalities was presented DDP – Preliminary project. It was sent for coordination to all companies, we are going to ask all the companies for exact coordinates of the infrastructural elements. This was already done for the power poles. We are going to ask all gas companies to give us the coordinates of the gas communications and to mark them on our maps. All the communication of the third parties will be marked on the map of our situation and on the 500-meters color illustration. Now we are collecting the information. But especially for the main pipeline, we have the information.

207 Participant in technical meeting from Polski Trambesh municipality

It is possible the affected landowner to have questions. Are you going to organize meetings in the affected settlements?

Response: When the final project is done, it will be defined exactly where the route passes. Gaspipeline is buried, so the landowners will be compensated once for the right of way, as well as for the lost harvest during the construction.

208 Participant in technical meeting from Polski Trambesh municipality

What is the distance between the existing pipeline and the future pipeline?

Response: The minimum distance, coordinated with Bulgartransgas, is 35 m. On the sites where pipes are crossing, the distance is 50 m; on the sites where potentially is going to have detonations – 100 m. On many sites we had to take away the pipes. According to Bulgarian legislation the minimum distance in agricultural areas is 32 m, but we have conformed the

page 149 of 156

distance to Bulgartransgas’ request – 35 m. Our idea is the smallest possible infringement of the rights of landowners.

209 Participant in technical meeting from Polski Trambesh municipality

What about the fences? Are they going to stay permanently?

Response: The fences are going to stay only during the construction. After that they will be removed. Until now in such projects there was no requirement for fences. This requirement is made by Penspen. The aim is to ensure maximum security.

210 Participant in technical meeting from Polski Trambesh municipality

Is there any possibility for hiring of local personnel?

Response: Having in mind the extremely specific activity, specialists are required. But still there is need of work force – these specialists are going to eat, sleep here, they are going to require service personnel. We consider that such personnel will be required. But we can not tell you exactly how many and what personnel.

211 Participant in technical meeting from Polski Trambesh municipality

What is the guarantee for our security?

Response: Investment of the international financial institutions, harmonization of our standards with the European ones, 24-hour monitoring of the above ground facilities, pipes’ width, 100% test of the weld, as well as hydrotest – all this things assure safe exploitation. Practice shows that incidents with gaspipelines are prorogued by third parties. All security measures are taken, the guarantee is high, be we have always to be careful.

212 Participant in technical meeting from Polski Trambesh municipality

What is the depth of the gaspipeline?

Response: Minimum of 1 meter coverage. As the diameter is big, I suppose that we are going to go down to 1,20-1,30 m, we are going to have bigger coverage of the gaspipeline, but the minimum that has to be observed is 1 m.

213 Participant in technical meeting from

You are speaking for social study. What is the significance of the ordinary people’s opinion for you?

Response: The European institutions want people to be informed, to know that the project won’t change their lifestyle. The banks want to protect their own financial interest from all possible aspects. They are trying to evaluate risks in maximum extend.

214 Participant in technical meeting from Polski Trambesh municipality

How much people and technique do you expect on the route during construction?

Response: We are doing the calculations right now. We expect around 10 heavy trucks, 5 excavators and around 10-12 pipeline layers which lay down the pipe into the trench. There are also trucks – 10-15, that service the route in different ways – supplies, personnel transport and so on. We expect that it is going to be quite dynamic, but our aim is to finish the cycle as fast as possible. I have already spoken about compensation, security and crossing of roads, but we have

page 150 of 156

also to ensure control and normal crossing of the gaspipeline. Agricultural technique and livestock are going to cross without problems the gaspipeline.

215 Participant in technical meeting from Polski Trambesh municipality

Do you expect a compressor station in our municipality?

Response: We are still doing calculations, but according to the preliminary data – no, we do not expect. It is possible on the area of your municipality to be located one sectional valve station, on 30-40 m area – one important facility that has to be secured.

216 Participant in technical meeting from Polski Trambesh municipality

Compensations are going to be only for the construction strip?

Response: Yes, only for the 36 m.

217 Participant in technical meeting from Polski Trambesh municipality

Where the construction technique will pass?

Response: Only in the construction strip, thanks to the fencing there is no way to enter or go out of the construction strip without permission.

218 Participant in technical meeting from Polski Trambesh municipality

How the assessment of the compensation will be made?

Response: The assessment will be expert, based on the real damages, made by the construction. If there is sown wheat and the landuser will gain 100 lv. from its sell, we are going to give him 100 lv. (actually he wins, because he does not pay the seeds). Moreover he will ne paid once right of way.

219 Participant in technical meeting from Polski Trambesh municipality

And what if the landowner and the landuser are not the same person?

Response: Then the landuser will be compensated.

220 Participant in technical meeting from Polski Trambesh municipality

Are the contractors the same from the beginning to the end of the project?

Response: This unique project and the construction technique needed are unique as well. I suppose that the construction technique and the constructor will come from abroad, that foreign construction companies will win the auction. But it is logical unqualified personnel to be hired from the local population – it’s cheaper. These are my expectations.

page 151 of 156

221 Participant in technical meeting from Podrim municipality

How many kilometers from the gaspipeline’s route exactly pass through our municipality?

Response: We have not calculated this.

222 Participant in technical meeting from Podrim municipality

Why the name Nabucco was chosen?

Response: The name comes from the opera “Nabucco” – with nice content and good end.

223 Participant in technical meeting from Podrim municipality

Is there any possibility local work force to be hired?

Response: It is not chosen an EPC contractor yet. I expect the project to be performed by a European company that has the needed construction technique. We don’t have such technique in Bulgaria. But this does not mean that in using foreign EPC contractor, there will have no need of local servicing personnel. We expect that some jobs will be opened for local work force.

224 Participant in technical meeting from Podrim municipality

In case of earthquakes or natural disasters are the expected activities on the valve stations coordinated with the local authorities?

Response: All the valve stations and facilities are tested for seismic activity. In Provadia there is a compression station of the existing pipeline that also was built by us. During the earthquake recently there was no problem. For this project we have applied high risk assessment due to the bank requirements that will finance the project. They do not want to risk.

225 Participant in technical meeting from Podrim municipality

How the pipeline will cross the Bosphorus and Danube river?

Response: The pipe crosses Marmara Sea close to Dardanelle, it will pass offshore, this means on the seabed. Particularly Danube river – we have three crossings of Danube river that are discussed at the moment. At the moment the methods of crossing are being specified – if it is going to be open cut method or HDD method – one expensive, but applicable method.

226 Participant in technical meeting from Podrim municipality

Is this project an alternative and concurrence of South Stream or not?

Response: In the society, thanks to the media that likes to make scandals, the projects are seen as concurrence. But we do not consider that South Stream is a concurrence, but another one possibility for gas supply from Russia. In Bulgaria this topic is politicized. And have to be considered as something ordinary, like going to the supermarket for example, because the gas is ecological, pure and easy for use fuel. That is why we do not consider South Stream as a concurrence.

227 Participant in technical meeting from

Is this project 100% private?

Response: According to us, the project could be considered as 100% stated-owned, because it is

page 152 of 156

Podrim municipality

made by the national companies of the countries.

228 Participant in technical meeting from Podrim municipality

From where the gas will come? You have mentioned Egypt.

Response: Gas will come mainly from the Caspian region. There is possibility for Egypt – the gas could be liquefied and transported in containers. There is also such variant.

229 Participant in technical meeting from Podrim municipality

How exactly you are negotiating gas from Turkmenistan when there is no gaspipelines in this country?

Response: We are currently working exactly on this scheme – together with the preparations of the project are made also the trade negotiations. The aim is when the projects are finished in 2015, to start functioning immediately.

230 Participant in technical meeting from Podrim municipality

In our municipality there are active hunters. What about the 500-meter zone in 2012 when the construction starts?

Response: In the construction strip it is forbidden to shoot.

231 Participant in technical meeting from Podrim municipality

The reorganizations of the roads are going to be coordinated with the municipality, aren’t they?

Response: Yes, of course. Our wish is not to close roads.

232 Participant in technical meeting from Podrim municipality

What if your construction machines damage our municipality roads? Who will pay for the repair?

Response: Each one damaged elements will be restored. The roads will be specially adjusted for heavy machinery transport. This will be coordinated with you.

233 Participant in technical meeting from Podrim municipality

How the project construction will affect positively the existing infrastructure?

Response: We are going to create transport scheme for the heavy machinery transport. They will be transported with special platforms, with rubber wheels and will be placed directly to the construction strip.

234 Participant in technical meeting from Podrim municipality

There is a railway. Is it possible the railway to be used for the transport?

Response: The transport plan for the pipelines will be developed when we know on which port they are going to arrive. There are variants for main pipeline yards at Yambol, Sliven and Pleven. At the municipalities there are smaller yards.

page 153 of 156

235 Participant in technical meeting from Podrim municipality

Where exactly the pipeline will pass next to our villages, now the existing pipeline is passing here. Are you sure that the pipeline will not cross the villages?

Response: The gaspipeline crosses on three places the existing pipeline. You can be sure that the gaspipeline will not cross the villages. The minimum distance between the existing pipeline and the new one is 35 m.

236 Participant in technical meeting from Podrim municipality

There is a rent for land use during the construction and not expropriation of the land, isn’t it?

Response: There is expropriation only for the above ground facilities. It is possible on the territory of your municipality to be built just one valve station. For the whole route it would be paid once right of way and for the harvest the owner or the landuser will be compensated.

237 Participant in technical meeting from Podrim municipality

What will be the depth of the gaspipeline?

Response: Minimum 1 m from the upper end of the pipe.

238 Participant in technical meeting from Podrim municipality

It is forbidden for perennial at all, isn’t it?

Response: Just in the construction strip.

239 Participant in technical meeting from Dolni Dabnik municipality

Is there an option local construction companies to participate as subcontractors?

Response: The project is at very high technological level, a special technique will be required. But there is a work together with the pipeline. For example possible areas for temporary pipe yards, for organizing worker’s camps. My expectation is that we can rely for unqualified work. It will be necessary the local people to work for the project – I don’t know if it will be whole company or separated jobs, but people for security, shops, trade will be required.

240 Participant in technical meeting from Dolni Dabnik municipality

Is it possible local companies to use the gas from the gaspipeline?

Response: In only one place – at village Losenets is planned connection of the existing pipeline with Nabucco. If separate villages want to be gasified, the gaspipeline already exists. In our gaspipelines there is a great potential. And Nabucco is a guarantee that can protect our needs in a crisis, as the one from the last year.

241 Participant in technical meeting from Dolni Dabnik municipality

We need the exact coordinates in villages land in order to be useful for you.Response: During the project development you are going to receive the exact coordinates of the route, as well as owner’s register. This will be one long procedure and you will be permanently informed for it. In some cases it’s only you that can give us the necessary information. In regard to above ground objects – in Dolnik Dabnik’s area are not expected special facilities. There is possibility for one valve station, the land for which will be bought, but it’s only around 1 dka.

page 154 of 156

242 Participant in technical meeting from Dolni Dabnik municipality

When and how will we begin to reconcile future investment proposals with the Nabucco project?Response: In the beginning of the last year you had this possibility. The material was presented to us and we’ve analysed it. But if you have skipped something, I can calm you: if there is such proposal, you will not be able to accomplish it. The distance between out pipeline and the existing gaspipeline is 35 m. It is a preventive zone in which construction is forbidden. The purpose of the agricultural land could not be changed. You are in the scope of the preventive zone of the existing pipeline, so it does not depend of Nabucco.

243 Participant in technical meeting from Popovo municipality

Is there any assessment on the percentage of the arable land, which will be affected by the construction of the gas pipeline? And accordingly is there division on categories of the arable land, irrigated arable land, etc.? We have been informed by the geodesists, working on the surveys, which no irrigation channels, hydromelioration or siphons were taken into consideration.

Response: Arable lands are included in the DDP – Detailed Development Plan and will be presented to the municipal authorities. Geodesists implement their strict duties and are not aware of the research and analysis work, which has been completed in addition to theirs. In regard to your concerns about the siphons – there is restriction on crossing them during construction and if yet there is such crossing the gas pipeline route will be conformed to the siphons and dislocated.

244 Participant in technical meeting from Popovo municipality

Is the project conformed to other projects, which are at an early stage of research and approval by the respective authorities? We are left with the impression that no such activity has been undertaken.

Response: One of the most important considerations during project planning is the presence of investment proposals from third parties. This leads to ongoing correction and reassessment of the gas pipeline route. It should be clear, that if there are any projects at a very early stage of their development, when it comes to their development they have to be confirmed to the Project Nabucco.

Previous year was issued a questionnaire to the affected municipalities for investment proposals. The DDP – Detailed Development Plan is also in preparation phase. Regarding the sensitive issue about the dam at the Cherni Lom River, due to the development of the project, the projector has required preparation of a so called offshore project implementation at the affected area, so that the municipality may finish the dam project as soon as it is able and willing to do so. The DDP – Detailed Development Plan contains four volumes with comprehensive data, organised as follows:

Volume 1 – Detailed Development Plan – the gas pipeline route is plotted over coordinate plans – topography maps form 1970

Volume 2 – all above ground installations (about 15 valve stations and other above ground installations)

page 155 of 156

Volume 3 – all the lands, which will be used temporary in return of compensations for the owners

Volume 4 – list-register of all land owners within the 500 m corridor.

245 Participant in technical meeting from Popovo municipality

What is the distance between the existing and the planned gas pipelines? Response: The minimum allowed distance between existing and new gas pipelines is 35 m., which is coordinated with the current owner of the existing national gas pipeline system – Bulgartransgas (Regulation 16 on servitude area). In addition, alongside the existing gas pipeline will be situated the shorter 12 m. side of the construction strip.

246 Participant in technical meeting from Popovo municipality

North of Kovachevets is planned wind farms to be build. It is true that the leading principle first on time first on site, but there are limited physical locations, which are most appropriate for such investment proposals.

Response: We are willing to confirm all investment proposals and see no obstacles for conforming Nabucco to such wind farm projects. It is important to stress out that within the 500 m. corridor could be made changes of the route and we would like to invite the respective authorities to contact us with maps, so that we could compare the investment proposals and see if there is any conflict between them at all.

247 Participant in technical meeting from Popovo municipality

Unfortunately we expect to have problems with the same land owners and users for the servitude area.

Response: The plans for building the Project will be presented to all of the affected parties. All of the owners will be compensated for the period of construction and exploitation of the gas pipeline.

248 Participant in technical meeting from Popovo municipality

As our experience shows, nevertheless there are obstacles and delays in receiving the above mentioned compensations and apart from that lands and crops are trampled after the construction. Response: The project is subdued to many strict requirements and such problems will be carefully avoided with the use of corresponding measures and monitoring forms the international financing bodies.
