1. BACKGROUND

Additional Financing for Electricity Supply Reliability Project (ESRP AF), requested by theGovernment of Armenia, intends to increase the reliability and capacity of the transmissionnetwork through rehabilitation/replacement of key transmission assets. To achieve thisobjective, the ESRP AF would include complete rehabilitation and expansion of Haghtanaksubstation of High Voltage Electric Networks CJSC (HVEN). The substation wascommissioned in 1988 and has not been rehabilitated since then. The key equipment andsupporting structures need replacement because of lack of maintenance parts and erosionof concrete foundations and steel supports. Poor equipment condition sometimes leads tounnecessary outages due to equipment failure. As part of the preparatory work forrehabilitation and expansion of Haghtanak substation, an Environmental Management Plan(EMP) is required.

2. PROJECT DESCRIPTION

Location and Site description

Haghtanak substation is located in the Western part of the capital city of Yerevan. Yerevan issituated in the north-eastern part of Ararat Valley, to the center-west of the Armenia. Theupper part of the city is surrounded with mountains on three sides while it descends to thebanks of the Hrazdan River at the south. It borders with Aragatsotn, Kotayk, Ararat andArmavir marzes of RA. The city's elevation ranges between 865 to 1390m above sea level.

The climate of Yerevan is a humid continental semi-arid climate, with hot and dry summersand cold and snowy winters. The average temperature in July is 25.8 C, and the absolutemaximum temperature is 42 C. The average temperature in January is -3.6 C, and theabsolute minimum temperature is -28 C. The average annual temperature is 11.9 C; averageannual relative humidity is 61%; average annual precipitation is 291-353mm.

Being located in a developed area, there is no wildlife within the area of constructionactivities. The substation is constructed within the re-cultivated territory of a closed tuffquarry. The construction site has flat topography and is surrounded by small-scale vineyardsto the south and south-east and by small production units to the west and south-west. Thevineyards are owned by the residents of neighboring rural communities and are cultivatedby them for personal use. An undeveloped land is located to the north of the substation.The closest residential area is about 300 m. There is a small water stream in 7 m distancefrom the southern fencing of the site.

The public road near the SS entrance will be used to access the site from the north. Thereare also access roads around SS fencing. Using of access roads will not restrict access toagricultural lands. All construction machinery and equipment will be parked inside the


4

fencing area. The project implementation will not have any temporary or permanentimpacts on neighboring production units.

The substation has: (a) two 220 kV overhead transmission lines (OTLs), (b) two 220 kV maintransformers (MTRs); and (c) three 10 kV feeder bus sections. One of the MTRs is220/(35)/10 kV 20 MVA transformer and the other is 220/10/(6) kV 63 MVA transformer.

The Substation occupies the fenced area of 2.6 ha with various` buildings having thefollowing external dimensions (L×W×H):

Control and dispatching building (including offices and battery room):41.7×12.05×5m;

10 kV feeder bus sections and two associated buildings:

36.7×9.1×5m and 15.9×5.18×5m each; and

Checkpoint: 6×3×4m.

The west side of the substation is currently used as decommissioned materials andequipment storage.

Project scope of work

The rehabilitation and expansion of the substation will involve the following:

replacement of two 220 kV main transformers (MTRs);

complete replacement of 220kV open switch-yard (OSY);

construction of new 110kV OSY with four bays for overhead transmission lines(OTLs);

demolition of existing and construction of new control and dispatching building;

replacement of Alternating Current and Direct Current (AC/DC) systems, includingdistribution system, chargers, invertors, and batteries;

installation of SCADA system and replacement of protection relay equipment;

replacement of 10 kV cubicles and the associated building;

reconstruction of grounding system;

reconstruction of oil spill collection system;

construction and reconstruction of roads and walkways;

rebuilding of cable trenches;

installation of fire alarm and fire localization system;


5

construction of external water drainage and reconstruction of sewerage system;and

restoration of outdoor lighting.

All of these activities will take place in the area of an already existing substation (as shownin Figure 1) and all impacts will be confined to the existing substation yard.

Figure 1: Site Plan

3. LEGISLATION

The following Armenian legislation defines a legal framework applicable to project activities:

Law on Atmospheric Air Protection of RoA (1994)

The purpose of Law on Atmospheric Air Protection is to define main principles of the RoA,directed to provision of purity of atmospheric air and improvement of air quality, preventionand mitigation of the chemical, physical, biological and other impacts on air quality andregulation of public relation.

According to this law, contractor shall undertake demolition and construction activities aswell as transportation and temporary storage of wastes the way to minimize dust and otheremissions to the air.

Law on Waste of RoA (2004)

The law provides the legal and economic basis for collection, transportation, disposal,treatment, re-use of wastes as well as prevention of negative impacts of waste on natural


6

resources, human life and health. The law defines the roles and responsibilities of the stateauthorized bodies as well as of waste generator organizations in waste managementoperations.

According to this law, the waste generated by the demolition, construction, dismantling andinstallation activities should be recycled as appropriate, or disposed of in designatedlocations.

Law on Environmental Impact Assessment of RoA (1995)

The law defines type of activities which are subject to environmental impact assessmentand ecological expertise.

According to this law, works planned at Haghtanak substation are not subject to theecological expertise.

Law on Urban Development of RoA (1998)

According to this law, works planned at Haghtanak substation require obtaining of theconstruction permit.

4. PUBLIC CONSULTATIONS

The neighboring communities of Haghtanak substation are considered to be the affectedparties during the construction and operational phases. EMP will be disclosed on the HighVoltage Electric Networks CJSC website. Brief information on the planned works and contactinformation for addressing questions and grievance will be placed at the work site and/or inits immediate surroundings/municipality.

5. POTENTIAL IMPACTS AND MITIGATION MEASURES

The EMP covers environmental and social impacts that may arise from the projectimplementation and provides mitigation measures to cover typical impacts from upgradingequipment and installing new equipment at substations, including workers’ health andsafety, earthworks, and solid and hazardous waste management. EnvironmentalManagement Program containing management and monitoring plans by project phase andactivity is provided in Annex 1.

Waste management is the most challenging task of the environmental mitigation plandeveloped for the project. The main types of wastes expected at the construction phase are:(i) non-hazardous - demolition debris; other types of non-hazardous construction waste;excess material from excavation; obsolete equipment; and (ii) hazardous - lead batteries andbattery acids; used transformer oils; used tires, filters, and oils of construction machineryand vehicles.


7

Non-hazardous - demolition debris and other as well as excess material from excavation willbe disposed to the formally designated locations. Permission for disposal from the YerevanMunicipality shall be obtained by Construction Contractor prior to disposal.

Obsolete equipment will be stored at Haghtanak SS site before being sold or possible reuseby HVEN. A separated outdoor area in west side of the SS plot will be used asdecommissioned equipment storage.

The maintenance of construction machinery and vehicles will be performed at specializedservice centers, which also accept used tires, filters, and oils.

Transformer oils at Haghtanak SS were assessed by the Waste Research Center SNCO of theMinistry of Nature Protection of RoA in 2010 using DEXSIL L2000 DX analyser. According toassessment results, the transformer oils at Haghtanak SS do not contain PCBs. Since atpresent there is no local licensed recycling facility, the used oils will be transported 3 kmnorth-east to Shahumyan-2 SS of HVEN and stored there in appropriate oil storage beforerecycling by a licensed contractor. Used oils will be transported in closed and sealedcontainers or tanks properly covered and immobilized by secure attachment totransportation trucks. Trucks will carry signage warning of hazardous cargo.

Since the disposal of decommissioned lead batteries and battery acid in a landfill isprohibited, while at present there is no local licensed recycling/neutralization facility in thecountry, the acid containing batteries must be transported 3.5 km north-east to MainBranch of HVEN and appropriately stored in warehouse building after removal of acid untilsuch kind of facilities will be established. Batteries should be protected against short circuitand secured from movement during transportation in an enclosed vehicle. The storageconditions will include locked and ventilated room with non-permeable floor material andthe shelves for placement of batteries. Acid will be stored in proper tanks having secondarycontainment. The trained HVEN staff will prepare the batteries and acid for storage. Properpersonal protection gear will be used by personnel when handling acid.

The EMP establishes a critical link between the management and mitigation measuresspecified in this report and the proper implementation and management of the measuresduring the construction and operation phases of the project. It provides details on themeasures responsibilities to mitigate these impacts; the costs of mitigation; and, the ways inwhich implementation and effectiveness of the measures will be monitored and supervised.

6. RESPONSIBILITIES AND INSTITUTIONAL ARRANGEMENTS

HVEN is responsible for the implementation of the EMP. The environmental managementplan table, extracted from this EMP, will be included into the tender package and will beincorporated into the contract for the provision of works, so that contractor is aware of the


8

mitigation measures to be applied, can properly cost them and include into the bill ofquantities, and is obligated to adhere to the EMP alike any other terms of the contract.

Responsibilities of Construction Contractor

HVEN shall obtain Construction Permit for the designed works. If any additional licenses,permits, consents required (e.g. waste disposal etc.) construction company shall obtain suchlicense, permits, and consents within its capacity.

Monitoring of EMP implementation

HVEN carries overall responsibility for the implementation of EMP and for organizingenvironmental monitoring of works. Environmental monitoring of works shall be undertakenaccording to the Environmental Monitoring Plan presented in this report and the outcomesof monitoring shall be documented in monthly environmental supervision reports.
