Training provided by Aal borq Energie Teehni k als (AET) Aalborg Energie Technik als (AET) is a Danish engineering company that develops, designs, engineers and builds complete biomass fired CHP plants up to IOOMW. AET have designed and will build the Monopower Biomass CHP Plant. Most of AET employees have more than 25 years of experience in power generating systems.

The business philosophy of AET is to develop, design, sell, erect, commission and service process steam plants and CHP plants fired with all forms of biomass, primarily wood chips, wood waste, sander dust and bark but also other bio fuels such as poultry litter, spent mushroom compost and meat and bone meal. The fuels are used separately or in combination.

AET also carries out consultancy work, overhaul and maintenance activities and assists in the operation and optimisation of operating conditions OR existing plants.

Although AET are very experienced in the safe operation of plant, it takes some time before the operation staff is sufficiently familiar with the plant to obtain optimal operation, Therefore once the plant is in place, AET train all operators. In addition they provide an experienced commissioning engineer for 20-40 hours work per week during the first 6 months after preliminary take over. The commissioning engineer will; - Support and train the operation staff - Avoid stops - Minimize stop time by fast action - Create contacts between Monopower operation staff and AET specialists in

Denmark.

Full written instruction manuals with all the information required for the operation and maintenance of the plant will be supplied by the Plant's design company prior to the commissioning phase. Fully updated data will be integrated into the operation and maintenance manuals after Commissioning and optimisation of the plant.

The manuals will describe the important aspects of the plant in detail and precisely by including lists of clearance, tolerances, temperatures, dimensions, weights etc. The documentation for erection will form part of the guidelines for assembling and dismantling the plant. The plant will adopt Environmental, Health, Safety and Quality operating procedures as part of its management system.

Wejghbn'dge: There will be two facilities for weighing lorries, one at the arrival entrance and one at the way out. The system to be installed includes computer and printing facilities for automatic calculation and registration of gross and net weights. Furthermore identification of lorries and fuel supplier, date and time can be registered. Weighbridges will be 18m long x 3m wide and have a capacity of 40 tonne.

Fuel Unloading Bulldlng & Fuel Screening: The fuel unloading building will have 3 bays, one each for the reception of SMC, PL and WC. Lorries will reverse into the required bay and deposit the fuel source into a hopperlfuel unloading conveyor. The poultry litter unloading bay will be maintained under negative pressure to prevent the escape of odour from this area. SMC and PL will travel from the unloading building through screens to remove metal, plastic etc. WC will travel to a shredder to reduce them in size, if required. Two plans of the fuel unloading building and shredding and screening building are provided in this attachment. See Map D. l (c) and D.1 (d).

Fuel Storage: After screeninglshredding fuel is stored in silos. These consist of 2 x 1 ,250m3 silos for SMC 1 x 1,250m3 silo for PL

0 1 x 1 ,250m3 silo for WC

Fuel Drying : Due to its high moisture content (70%), SMC requires drying prior to combustion. PL and WC do not require drying. There will be three rotary steam dryers which will reduce SMC moisture from 70% to 15%. The humidified air from the drying process will be removed and mixed with into the air system for the combustion process. Condensate removed from the dryers will be used in the flue gas cleaning process.

Fuel Feeding: Dried SMC is continuously transported from the drying plant via a buffer storage to the boiler fuel feeding system at the boiler front. PL and WC when used are continuously transported from storage to the boiler fuel feeding system at the boiler front.

Combustion System/Bo/ler: The combustion system will be equipped with three separate fuel feeding systems in order to handle the various types of biomass fuel, and one oil burner for start-up of the plant. 1. Spreader feeders for fuel composed of larger and heavier particles like wood

2. One set of nozzle burners for fuel composed of smaller and lighter particles

3. One set of nozzle burners for fuel composed of smaller and lighter particles

4. Oil burner for start up purposes and as a support burner during abnormal

Three separate fuel-dosing hoppers for the individual fuels will be arranged in the boiler house. Each fuel type will be regularly and automatically dosed into one of the feeding systems, which can all operate at the same time. In all three systems the fuel is fed airborne into the furnace at relatively high but different, speeds.

steam, which will drive the steam turbine. The boiler is a single-drum, natural circulation steam boiler. It is top-supported and consists of fully water-cooled membrane walls. The furnace is designed to provide sufficient residence time at a combustion temperature ranging between 1 20O-140O0C, ensuring proper combustion of the fuels.

The fuel is fed into the furnace where it will quickly dry and gasify. Smaller particles will burn out immediately in suspension. Larger and heavier particles will fall to the bottom of the furnace onto the traveling grate partially or completely gasified and will burn out gradually.

The traveling grate located at the bottom of the furnace consists of several endless chains, between the chains T-profiles are arranged, carrying the individual grate bars constituting the surface of the grate. The grate rotates slowly from the front wall to the back wall where the particles {Ash) on the grate fall from the boiler into the slagheap.

The hot gases produced in the furnace will give high heat transfer as they are drawn through the boiler evaporator, superheaters and economiser by a frequency controlled induced draft fan, which maintains a negative pressure of 50-200 Pa in the furnace.

Combustion Ai r System The combustion air system is divided into two systems - the primary air system and the secondary air system. The primary air system supplies air to the combustion grate. The secondary system supplies air to the nozzles located at a number of positions on the furnace front and back walls.

A mixture of fresh air and humidified air from the fuel dryers is used as combustion air. The air system is designed to operate using preheated air with high moisture content. The preheated air is necessary due to the high moisture content of the fuel.

A spreader air fan is used to provide air for the PL and SMC and transport air for the re-injection of unburned particles. The spreader fan is also used to supply air to pneumaticatly inject WC into the furnace if used.

The fresh air used as combustion air is drawn from the top of the boiler house in order to provide ventilation of the boiler house, and to recover some of the radiative heat loss from the boiler.

Humidified air from the dryers is mixed into the air system downstream of the fresh air preheater, but upstream of the fans. This air is subsequently split into the primary, secondary and spreader air streams.

The primary combustion air will be supplied into the air chamber from under the grate. From here the primary air will flow through small noules in the grate into the furnace. The primary air cools the grate and ensures an intensive burning of the fuel particles on the grate surFace.

The secondary air will be supplied through strategically arranged high-pressure air nozzles, ensuring a high turbulence and an intensive mixing of the oxygen and the flammable gases in the combustion zone above grate surface The boiler is designed with three passes. The first pass is the furnace, this is 25.5m high, in order to ensure good turbulence and a long residence time for the flue gases. This is necessary in order to achieve good combustion with low emission values. A tall furnace is further necessary in order to ensure efficient natural circulation of waterlsteam in the membrane walls during all possible load and fuel combinations. The second pass is a radiation pass that ensures a long residence time and a good flue gas cooling before the third pass, in which the super heaters are arranged. The superheated is split into four sections in the third pass.

When the flue gas turns around the bottom of the partition wall between the second and third passes, a large fraction of any unburned particles in the flue gas are deposited here. The collected particles are re-fired pneumatically into the furnace above the grate surface level.

Steam System The boiler will be of the natural circulation type consisting of water-cooled furnace, an economiser, evaporator and four super heaters. Steam temperature will be controlled by spray attemperators by injection of boiler feed water.

The water will first enter the boiler via the economiser, where the feed water is preheated before entering the steam drum where it is mixed with boiler water. The feedwater will be admixed with chemicals from a low pressure-dosing pump at the low side of the feed water pumps. The boiler water will be admixed with chemicals from a high pressure-dosing pump directly into the steam drum.

From the steam drum located directly above the furnace the boiler water is passed to the bottom headers through external, unheated down pipes. The evaporator system consists of all membrane walls, which forms a fully welded and gastight construction. From the membrane walls the heated mixture of water and steam is led back to the steam drum,

In the drum the waterlsteam mixture will be separated by means of specially arranged plates and cyclones. The water will be returned to the waterlsteam circulation system. The steam will pass through a steam dryer at the top of the drum, and is by means of connection pipes lead from the steam chamber in the drum to the super heaters that will dry and superheat the steam.

Dissolved solids in the boiler water will be controlled by an intermittent blow down and drainage system.

Four drawings are provided of the Boiler, Turbine and Services Building. See maps D.l(e), D.l(f), D.l(g), D.l(h).

Steam Turbine Generator & Air cooled condenser (Cond8nslng economiser): The high-pressure steam produced in the boiler will be used to generate electricity in the steam turbine generator. The steam is received from the boiler at 69 bar and 450 "C and passes through the turbine, the steam exits the turbine at 0.08 bara and 47.1 'C. During normal operation, the turbine

generator will generate 20MW electricity for export. The 1 I kV steam turbine generator has a nominal rating of 23MVA.

After passing through the turbine the steam is condensed in an Air Cooled Condenser (ACC) where it condenses and returns as condensate, which is pumped, back to the boiler through the boiler feed pumps from a standard de- aerator. The feed water receives further heat in the economiser and is passed to the boiter drum, where saturated water is circulated naturally in the furnace evaporator tubes. The ACC consists of 3-5 sections, each with 1 fan. The steam wilt run through tube bundles which will be arranged as A-frames, where the tube bundles are divided in a counterflow coupled condensation part and a downstream coupled de-phlegmator part to keep the ACC freeze resistant.

The turbine will be provided with a steam bypass system to directly discharge steam to the condenser. This bypass will allow the boiler to continue to operate without requiring boiler shutdown, when the system experiences upset caused by loss of grid connection or short-term loss of the turbine. Also, the boiler is able to operate without the turbine during start up and turbine trip.

The plant will be provided with a steam pressure reduction station, which will always be capable of supplying the required steam quantity necessary to the drying process. Thus the heat supplies for the fuel drying process will be guaranteed independent of the turbine mode.

The turbine is equipped with three bleeds (20, 10, 1.65 bara) and one extraction (6 bara) for preheating of feed water and combustion air, and for drying of SMC- fuel.

A closed cooling circuit is used for the cooling of the generator, the turbine lubrication oil system, the sampling, the feed water pumps and the ash screw. The system consists of two air coolers, two 100% recirculation pumps and an expansion tank.

Condensate System The condensate system collects the condensate from the ACC and from the drying and preheating processes. The process condensate will pass through a filter before it returns to the feed water tank. Thus the boiler plant will be protected from any damaging impurities.

Flue Gas Cleaning System; The flue gas cleaning system, which is a dry absorption system applying quick lime as reagent, is based on a simultaneous conditioning of the gas and removal of the acid components. The conditioning is by means of evaporative cooling with water to a relative humidity of approximately 40% and the acid gas removal by introduction of lime to the flue gas. The system is based on an integration of the gas absorption system with the dust removal equipment.

Lime arrives to the site in closed tank lorries. These are emptied by fluidisation, and the lime powder is pneumatically transported up into the top of the silo. This system is also kept on a negative pressure to avoid dust. The rate of lime consumption for this process is 950 kglhr during normal operation.

Operating principle Hot, untreated flue gas from the boiler, when introduced into the reactor via a gas disperser, contacts a free flowing, humidified powder of lime and, re-circulated mixture of reaction product and fly ash. The reactive gas components are rapidly absorbed into the alkaline components of the powder. Water is simultaneously evaporated to reach the flue gas temperature required for efficient absorption of SO2. The control of gas distribution, powder flow rate and distribution, and the amount of humidifying water ensures the appropriate conditions for optimum SO2 remova I em cie n cy.

The treated exhaust gas flows to a fabric filter (baghouse filter) for particulate control where particles in the flue gas are removed. Clean outlet gases from the particulate collector are transported to the stack by means of the induced draft fan. The solids collected are either recycled to the reactor via a humidifier system or stored as fly ash.

Mixer Humidifier The dust from the fabric filter is humidified in fluidised mixing equipment, where also fresh lime is added. The dust recirculation and water addition is controlled to give flue gas cooling to a set temperature, and the lime addition is controlled to give a set SO2 emission.

The absorbent is mixed into the flue gas in the reactor, which is a mixing zone of the flue gas duct where high shear forces and high turbulence are created.

Reactor The integration of the humidifier and the reactor ensures an even distribution of the absorbent across the flue gas duct cross section to avoid any areas of under- stoichiometric conditions.

The reactor is designed to create adequate turbulence for efficient mixing of gas and absorbent over the entire load range. The distribution of dust and gas is critical for the operation of the process.

The advantage of a two-point discharge system lies in the avoidance of blockage in the gas passage, even in the event of process disturbances. Besides SO2 the small amounts of SO3 always present in boiler flue gas are nearly completely absorbed in the reactor, since the droplets on which SO3 condenses, forming the calcium sulphate salt, are alkaline.

Dust Collector - Bag filter The dust collector for the flue gas cleaning system is a bag filter, and is located down-stream of the reactor and collects the dust formed during the cleaning process as well as fly ash in the flue gas. The filter is adjusted to actual application and the special requirements on a filter when integrated with a de- sulphurization system.

The filter is divided in rectangular shaped compartments. The bags are mounted on individual cages and top supported in gas tight holes in a horizontal steel plate separating the dirty gas side from the clean gas side.

The dusty gas from the reactor passes into the filter compartments, where it looses velocity due to the large volume of compartments. Heavy dust particles will be precipitated in the bottom hopper by means of gravity, while the remaining particles will pass with the gases into the filtration area.

In the filtration area the dust particles will be deposed at the outside of the filter bags. The clean flue gas pass through the bags and into the clean gas side and out through the outlet duct and damper system.

A hopper is located under each compartment for collection of dust (fly ash and reaction product). The dust from the bags falls directly down into the bottom hoppers, and from there it is transported to the fly ash silo or back to the reactor.

Wafer Treatment Plant: A dedicated on-site well will provide all of the required process water for the biomass power plant. Initially, the water will be used to fill the boiler and subsequently it will provide make-up water to the system. The make-up water is required for blowdown replacement for the boiler, necessary to maintain boiler purity, for steam used in the soot blowing process and other various consumptions (sinks, toilets, etc.). The average water requirement will be 3.75 m3/hr during normal operation and 1 Om3/hr during abnormal operation according to the processes with or without the condensing economizer operating.

The water treatment equipment consists of a standard Demineralisation plant based on a reverse-osmosis plant and an ED1 plant (electrode-deionisation). The equipment would be regarded as environmentally friendly, with low operation cost and without use of chemicals for demineralisation and without any subsequent neutralisation of the drain water from the plant. The demineralised water will be admixed with chemicals from a high pressure-dosing pump to maintain the correct pH balance and to minimise waterlsteam side corrosion.

Ash Removal Plant: There are two types of ash produced in the biomass power plant, the bottom ash from the boiler and fly ash from the flue gas. The ash from the traveling grate surface and slag from the combustion chamber is transported to the front edge of the traveling grate, where it falls into the submerged slag conveyor to form one product known as bottom ash. A combination of dust, fly ash and lime with absorbed SO2 and HCI, is continuously removed from the flue gas cleaning system by a side stream from the bag filters to form one product known as fly ash.

The two ash systems will have different characteristics. The bottom ash will be of varying particle size. The bottom ash drops directly from the traveling grate down into a water filled trough from which it is drawn up by a conveying chain. The bottom ash is kept under the water surface in the slag conveyor in order to compensate for the difference in pressure between the combustion chamber and the atmospheric pressure. From the conveying system the bottom ash is dropped into closed and portable containers located in the boiler house.

The containers will be picked up by lorry and taken away from the site. There will be no fugitive dust emissions associated with this process due to the wetting of the ash. The quantity of bottom ash produced will be approximately 2300 kg/hr.

Fly ash wil! come from the fabric filter (baghouse) and will have a small particle size and will be a consistent quality. After collection of the ash on the bags, ash will be discharged into hoppers using a pulse jet cleaning method. A pneumatic conveying system will be located beneath the collection hoppers. This end product is transported by the conveyor to a storage silo from which it is discharged on to vehicles for further disposal. The silo is kept on a negative pressure by means of a fan and a filter on top of the silo. Discharge of the fly ash is done by fluidization in the silo bottom. Discharge flows (like water) directly down into a closed tank lorry by means of a flexible tube connection. Dust is avoided by maintaining constant negative pressure in the system.

The discharged material is a dry white to grey free flowing powder, which can be handled as fly ash. The total quantity of fly ash produced will be approximately 3600 kglhr.

The ash produced will have a potential end market as a fertiliser or other end use. Its end use as a potential fertiliser will depend largely on the potash (k) and phosphate (P&) levels and this will not be quantified until the plant is operational. Detailed final ash characterisation will be carried out to determine its use in both existing and potentia! new utilization methods. The amount of solid waste generated at the biomass power plant that requires disposal is therefore expected to be small, non-hazardous and will be disposed of in accordance with licence requirements.

D.1 .e Wheel-wash A wheel wash will be installed on the site near the exit point, so that at1 vehicles leaving the site are clean, prior to returning to the public road. It is not envisaged that roadways within the site will get ditty as fuel is unloaded into hoppers within the fuel unloading building only, so both the hopper and building are enclosed and prevent waste materials being deposited on roadways. However a wheel wash can be installed at the plant as a precautionary measure.

D.1 .f Laboratory Facilities No laboratory facilities are proposed at this site as they are not deemed necessary, There will be a facility on site to test moisture and calorific value of each incoming load.

D.1.q Desian and location of fuel storage areas & D.1 .i Waste Inspection areas The fuel (Le. biomass) will be transported to the biomass plant by fully covered articulated lorries. Upon arrival at the pfant, the lorry will proceed to the weighbridge near the entrance and the driver will provide the required information (haulier identification, supplier identification and identification of fuel material type) prior to weighing. If the quality of the incoming fuel is acceptable, the lorries will be weighed at the weighbridge. The lorries will then proceed to the fuel reception building where it will reverse into the appropriate unloading bay; one for SMC, one for PL and one for WC.

When the lorry is fully within the fuel reception building, the unloading bay doors will dose. The load will be analysed for moisture content and the load wilt then be tipped into the fuel reception pit. After completion of fuel tipping, the lorry leaves

the fuel reception building and proceeds to the weighbridge near the site exit where it will be weighed again and the weight of the fuel delivered can be ca I cu I ated.

The reception bays will operate 6 days a week, 10 hours per day. The lorries will carry an average of 20 tonnes each, resulting in approximately 5-6 lorries per hour.

One 100m3 oil tank is proposed for this site. Oit is required for start up of the boiler. This fuel tank will be bunded to the required capacity i.e. 110% the volume of the largest tank within the bunded area or 25% of the total volume to be contained in the bunded area, whichever is the greater. The site will comply with this standard.

D.l. h Waste quarantine areas No waste quarantine areas are proposed at this site as they are not deemed necessary. Each load of fuel will be inspected prior to disposal in the fuel reception bay. Unsatisfactory loads arriving at the site will be rejected at source.

D.1.j Traffic Control Traffic control wit1 be maintained by having well marked access and exit routes, car parks etc. Details of the traffic control to be employed at the site are shown schematically on the site layout plan in this attachment. See Map D,l(a).

D.1 .k Sewerage and surface water drainage infrastructure A map of proposed drainage routes from the new site is included in this attachment. See Map D.l(i). A detailed drainage plan for the site has not yet been devised.

Sewerage Domestic effluent on the site, from toilets, sinks, showers and canteen areas will discharge to a dedicated treatment plant -a bio-clear treatment system. This system will be designed for a maximum of 25 staff (working 3 x 8hour shifts). Raw sewage from the administration and services building is discharged to an aerated tank, which fully treats the wastewater, prior to discharge to a percolation area. Within the percolation area, treated effluent is discharged via a network of pipes into the underlying soil, where it undergoes further polishing and treatment, prior to discharge to groundwater. The bio-clear treatment system is a fully enclosed plant, accepting only domestic-type wastewaters. No process water will be discharged to the bio-clear system.

Surface Water Dralnaqe An outline of drainage routes from the proposed site, once constructed is provided in the attached map. The existing drainage ditch flowing west-east across the centre of the site will be piped and will constitute the main drainage channel into which all surface water from the site will flow. This drain will link up with the ditch in the field beside the site, which will transport water to the stream, as is currently the case. Drainage from the site will be split in two so that water from the southern side of the main drainage channel will be kept separate from water from the northern side of the main drainage channel.

Electricity: Electricity will be generated on the site so the site will have its own power supply. Telephone; Telephone connections will be made to all required buildings on the site. Water: The water supply to the site will be predominantly from groundwater, from the bored well(s) on the site. The Truagh Group Water Scheme supplies water locally to the area, so this water source will likely be used to supply fire hydrants on the site and for potable water, if required. Pumping tests carried out on the groundwater resource at the site determined that the well was capable of yielding 650m3 of water per day, {27m3/hr) which is substantial. The estimated maximum requirement for water at the site is 10m3/hr (during abnormal operation) and the avera e water use requirement (for normal operation) is expected to be between 3-5m Ihr. B D.1.m Plant sheds, qarages and equipment compound Full details of buildings on the site are provided on the site layout plan in this attachment. The sewices building will be the main building where maintenance of equipment will be carried out.

D.2. Facility Operation

D.2.a) The proposed site is a Biomass Combined Heat & Power (CHP) plant. It will take in 3 raw materials; poultry litter (PL), spent mushroom compost (SMC) and wood chips (WC), which will be fed to a large steam boiler for combustion. The steam generated from this process will be converted via a steam turbine generator to electricity, which will be sold to the national grid. The capacity of the site will be 22.5MW of electricity per annum.

When the site is constructed, it will comprise a number of buildings, as shown in the site la out plan in attachment D1. The total site area is in the order of 7 acres (28,328m 1. Y

The site operation is summarised as follows; 12. Delivery of raw materials (fuellbiomass) to site via lorries i.e. poultry litter,

spent mushroom compost and wood chips. 13. Disposal of raw materials in the unloading building (each raw material kept

separate until combustion) 14.feeding of raw materials via conveyors to a screening area to remove

metal, plastic etc. 15. Storage of raw materials in silos; (2 x I ,250m3 silos for SMC, 1 x I ,250m3

silo for PL and 1 x 1 ,250m3 silo for WC). 16. Drying of SMC from 70% moisture to 15% moisture in 3 steam-heated fuel

driers. PL and WC will not require drying. 17. Feeding of raw materials (SMC from the drying plant and PL and WC from

the silos) to the combustion plant boiler. Each raw material will have a separate fuel feeding system. A 4 fuel-feeding system will be in place from an oil burner. Oil is required for start-up of the plant.

18. Combustion of the raw materials in the boiler to produce steamlheat. By- products of this process are ash and combustion gases.

19.Steam produced in the boiler is passed to a steam turbine generator, where electricity is produced. This is the final end-product of the production process.

20.A condenser unit is also located on the site to condense steam prior to returning it to the boiler.

21. Process ash generated on combustion of the fuel will be conveyed to and stored in a silo. This by-product will be transported off-site for use either as a fertilizer or in the cement industry.

22. Combustion gases from the boiler will pass through a flue-gas cleaning system, based on lime. Solids from this process will be conveyed to the fly-ash silo and gases will be emitted to atmosphere via a 50m stack.

Funitive Emissions The stack AI-1 represents the principal source of emissions to the air from the plant - however, in addition, there will be minor emissions of particulate matter from silos used to store process materials such as lime. There is also the potential for fugitive emissions of dust from the storage, handling and trucking of the biomass fuels and ash by-product. Specific control measures which will be implemented to mitigate against these include transport of fuel and ash in covered trucks, an enclosed fuel hall and maintaining fuel hall and storage area under negative pressure. Ventilation air from these areas will be drawn into the boiler to be used as combustion air facilitating thermal destruction of dust, odours and air borne pathogens.

The waste ash produced from the process comprises of both fly and bottom ash. Fly ash will be dry and dusty while bottom ash is wet. Removal of ash residues will be conducted in such a way so as to prevent emissions of dust. All components of the ash handling system (collection, conveyance, processing, storage and out loading) will be fully enclosed to prevent contact with the outside elements. Fly ash dust is avoided by maintaining constantly negative pressure in the system. Discharge will flow into a closed tank lorry by means of a flexible tube connection. Bottom (wet} ash will not be a source of fugitive emissions. Nevertheless it will be stored in portable enclosed containers located in the boiler house for removal. Both fly and bottom ash will be removed from site in covered trucks to prevent fugitive dust emissions.

Lime is another potential source of fugitive emissions. It will arrive to the site in enclosed containers which will be emptied by fluidization and lime will be blown pneumatically to the silo. To avoid dust emissions, this system will be maintained under negative pressure. A final usage of the waste ash produced will be dependant on its combined chemical composition. Possible end uses include sale as an organic fertiliser or use as a raw material in the cement industry.

Odour Poultry litter is an odorous material, the primary odorants likely to be amines, mercaptans, hydrogen sulphide and ammonia. The plant has been specially designed to minimise the impact of odours. When the facility is running normally the primary air for combustion will be taken from the fuel storage and tipping areas. This large volume of air will create an inward draft of air through the inlet louves and fabric of the building and the potential for odour escape will therefore be eliminated. When the facility is not in operation for any reason and the main boiler plant does not operate then the hot gas generator will be started. This will draw a flow of air from the fuel store thus maintaining the flow of air into the store and preventing odour escape. In the event of equipment failure or maintenance shutdown all vents will be closed in the fuel storage area to further reduce the risk of odour escape.

These design features, as well as the operating practices that will be implemented at the plant as well as fuel transport, will ensure that odours are properly contained.

E.2. Emissions to Surface Waters There is one main surface water discharge point from this site, from which all surface water falling on the site and any treated wastewater will discharge. This point will be labelled SW-I.

Emissions to surface water from this site will constitute 1. Rainfall from roofs and impermeable yard areas, which will be clean. All

fuel unloading takes place in enclosed building, so roadways and yards will not be permitted to become fouled. This rainwater will discharge directly via the surface water drainage system and leave the site via SW- I.

2. Two oil interceptors will be located on the site, which will discharge to the sulface water drainage system leave the site via SW-1. Oil interceptors will be checked and cleaned regularly and wet1 maintained.

3. A wheel wash will be located near the site entrance, which will discharge to a small settlement sump and hence to the surface water drainage system and leave the site via SW-1. The wheel wash will be checked and cleaned regularly and well maintained.

4. Boiler blowdown from the boiler plant will discharge to a balancing tank to provide temperature and chemical balancing, prior to discharge to the surface water drainage system and leave the site via SW-1.

5. Water softener effluent from the raw water treatment plant will also discharge to a balancing tank to provide temperature and chemical balancing, prior to discharge to the surface water drainage system and leave the site via SW-1.

Proposed Drainage

An outline of drainage routes from the proposed site, once constructed is provided Map E.2. A detailed drainage map of the proposed site has not yet been devised so is not currently available.

The existing drainage ditch flowing west-east across the centre of the site will be piped and will constitute the main drainage channel into which all surface water from the site will flow. This drain will link up with the ditch in the field beside the site, which will transport water to the stream, as is currently the case.

When the site is constructed it will comprise a number of buildings (administration, fuellraw materials unloading, shredding, boiler, turbine and service building). The total site area of buildings is in the order of 2,160m2 (7.6% of the total site area). Rainwater falling on roofs of these buildings will be collected via down pipes and discharge to the surface water drainage system outlined above.

Internal rimary roads and hard standing areas will be paved with asphalt (6,900m ). Areas for handling of containers etc. will be paved with reinforced concrete (450m'). Secondary roads for service access only will be paved with gravel (950m2}. The asphalt and concrete paving will be impermeable (7,350m2) so surface water drains I gullies will be installed along roadways and carparks to catch rainwater falling on these areas. This rainwater will discharge to the surFace water drainage system outlined above.

P

The remainder of the site will be permeable, allowing rainwater to percolate through the soil. This area will consist of 950m2 of gravet paving and the remainder will be grassllandscaped, comprising an area of approximately 1 7,868m2.

A process water pond is to be located on the site. This pond is designed to accept any process water generated from the production process. Water is stored here prior to discharge from the surface water system outlined above. The pond allows settlement of discharge water and allows the temperature to stabijise, prior to leaving the site. The pond will also be used as a firewater retention facility.

The site will be fitted with two oil interceptors, one at the oil tank loading area and one at the surface water discharge outlet from site at the eastern boundary.

Domestic effluent on the site, from toilets, sinks, showers and canteen areas will discharge to a dedicated treatment plant -a bio-clear treatment system. This system will be designed for a maximum of 25 staff (working 3 x 8hour shifts). Raw sewage from the administration and services building is discharged to an aerated tank, which fully treats the wastewater, prior to discharge to a percolation area. Within the percolation area, treated effluent is discharged via a network of pipes into the underlying soil, where it undergoes further polishing and treatment, prior to percolation to groundwater. The bio-clear treatment system is a fully enclosed plant, accepting only domestic-type wastewaters. No process water will be discharged to the bio-clear system.

In summary, all sulface water runoff from the site will discharge via over-ground flow and via the sulface water drainage system to the site outlet at the eastern site boundary and hence to the nearby stream. Process water will drain to a pond, prior to discharge to this location also. A large amount of surface water will also percolate through the soil to ground and groundwater, as over half of the site area (66.4%) is permeable (i.e. grassllandscaped).

Meteorological Data Annual average rainfall for the rainfall station at Emyvale, located 3.5km from the site is 966mm (30 year gauge station, provided

Noise Emission from site and Mitigation Measures The existing soundscape around the site is one with minor to moderate, heavy vehicular traffic (trucks), moderate mechanised agricultural traffic, moderate residential traffic and regular commuting traffic noise.

The plant will alter the acoustic soundscape of the site itself and introduce new noise sources to the locality. The impact of plant noise will largely be on microscale (Le. immediate vicinity of operations). The proposed development will alter the existing soundscape whereby the concentration of heavy vehicular heavy traffic will increase to moderate or marginally significant heavy traffic. Marginal increases in commuting traffic will result from employee movements.

The impact on background ambient noise levels (L90) will be negligible, however increases in the continuous equivalent noise level (Leq) will occur. The impact of the development on existing noise levels is subjective and will largely be from traffic noise associated with fuel delivery and not the power plant development. The fuel delivery trafFic is not continuous and the implementation of a traffic management plan will assist in reducing traffic noise associated with the development. The noise associated with traffic will be IocaIised, sporadic and concentrated along the main communication or access routes.

The likely future noise emissions arising from the new development and the equipment used has been predicted and the total amount of noise which would b e emitted from the site determined. In addition the amount of noise from the site which would be received at the noise-sensitive property or area identified in the survey has been predicted.

The following noise criteria, targets have been considered for this project: Day time (08:OO - 2200) 55dBIA) Night time (2200 - 08:OO) 45dB(A)

These criteria relate to emissions from the development as measured at the nearest or any private residence. Building design will be such as to achieve these criteria, including the incorporation of noise suppression materials into the building fabric as required. In the case of other significant noise sources, such as compressors or blowers, these will be located within block-built structures where similar design standards and specifications will be applied in order to ensure that these targets are achieved. Other measures that will be applied, as necessary, to meet these targets will include silencers on compressors and blowers, noise absorption panels, double doors and double glazing.

Safety regulations and good practice require that warning sirens be employed prior to starting up or operating particular types of equipment such as conveyors, mills and overhead cranes. Alarm bells or sirens will also be an integral part of the fire alarm system and will require occasional testing. All such noise sources, which will, by their nature, be intermittent and will be so located and screened to minimise noise emissions to the external environment.

No vibration sources are predicted from the operation of this plant.

Attachment E.6

E.6 Environmental Nuisance

Bird Contrul It is not envisaged that bird control measures will be required for this site, as all handling of biomass fuel takes place within enclosed buildings, so bird control is not considered necessary.

Dust Control The stack A I - I represents the principal source of emissions to the air from the plant - however, in addition, there will be minor emissions of particulate matter from silos used to store process materials such as lime. There is also the potential for fugitive emissions of dust from the storage, handling and trucking of the biomass fuels and ash by-product. Specific control measures which will be implemented to mitigate against these include transport of fuel and ash in covered trucks, an enclosed fuel hall and maintaining fuel hall and storage area under negative pressure. Ventilation air from these areas will be drawn into the boiler to be used as combustion air facilitating thermal destruction of dust, odours and air borne pathogens.

The waste ash produced from the process comprises of both fly and bottom ash. Fly ash will be dry and dusty while bottom ash is wet. Removal of ash residues will be conducted in such a way so as to prevent emissions of dust. All components of the ash handling system (collection, conveyance, processing, storage and out loading) will be fully enclosed to prevent contact with the outside elements. Fly ash dust is avoided by maintaining constantly negative pressure in the system. Discharge will flow into a closed tank lorry by means of a flexible tube connection. Bottom (wet) ash will not be a source of fugitive emissions. Nevertheless it will be stored in portable enclosed containers located in the boiler house for removal. Both fly and bottom ash will be removed from site in covered trucks to prevent fugitive dust emissions.

Lime is another potential source of fugitive emissions. It will arrive to the site in enclosed containers which will be emptied by fluidization and lime will be blown pneumatically to the silo. To avoid dust emissions, this system will be maintained under negative pressure. A final usage of the waste ash produced will be dependant on its combined chemical composition. Possible end uses include sale as an organic fertiliser or use as a raw material in the cement industry.

Fire Control A number of measures are proposed to ensure fire safety at the site. The site will comply with all f re regulations in terms of building structures, emergency provisions and fire fighting equipment, and all other stipulations set out by the local fire safety officers.

Fire safety systems and fire fighting equipment will be strategically located throughout the site. The systems and equipment provided will allow for the early

extinction of a fire to ensure minimum risk to employees. This in turn prevents the generation of contaminated firewater.

An automatic fire detection system and break glass points will be installed all main processing buildings on the site; - Fuel unloading building - Boiler house - Turbine hall - Services building The fire alarm will have both audio and visual alarms.

Alarm panels with 10 zones will be placed in the control room in the service building.

Fire extinguishing systems to be provided at the site include; - 4 external fire hydrants - Hose reels & dry powder fuel unloading building, boiler and turbine building,

service building and oficeladministration building.

Emergency telephone numbers of the local fire brigade, garda, doctors, ambulance and hospital will be posted in prominent locations throughout the site. Fire escape routes will be clearly identified and maintained available for use.

A safety statement will be devised for the site once constructed. This safety statement will include the company and site information to be adhered to in an emergency event i.e. emergency response procedure. All staff on the site will be fully trained in the safety aspects of the operation.

The Local fire-fighting unit will be invited to the site to relay details on site processes, chemical storage arrangements, flammable materials, hydrants, site access etc. Any suggestions OF improvement measures deemed necessary by the local fire fighting team will be taken on board by the company.

The Local Fire Fighting unit, based in Monaghan town have 2 main pumps and one Emergency Tender Rescue Unit. There are three full time officers in the local fire brigade, the Chief Fire Officer and two Assistant Chief Fire Officers. In addition to this there are 9 firemen. The back-up services available to the local fire unit include that from the outside towns. These include the Clones, Ballybay, Castleblaney and Carrickmacross Fire Units. The response time of the local fighting unit in the event of an emergency call to the site would be between 10- 15mins.

Litter Control It is not envisaged that litter control measures will be required for this site, as all handling of biomass fuel takes place within enclosed buildings.

Traffic Control Articulated vehicles will be used for the collection of SMC and PL. Collection trailers will be 10m long, 2.4m wide and 2.2m high. Trailers will hold 20-25 tonnes of either SMC or PL. Deliveries will be made between 8.00am to 6.00pm from Monday to Saturday. A summary of raw material deliveries to Site (on an annual

In the planning application for this development, a road upgrade study has been undertaken and submitted for the two minor roads teading to the site; one from the N2 National Primary Route, a distance of 4km to the site and one from the R186 Regional road, a distance of 3km from the site.

The following measures wilt be adopted to mitigate the impacts of operational traffic associated with the development:

The primary mitigation measure will be the upgrade of the minor roads connecting the site to the N2 and R186 to a standard that will prevent disruption of the existing traffic flow. The upgrading of the roads will include the widening of the carriageway width and improvement of the road surface quality.

The delivery of SMC and poultry titter will be restricted to 10 hours per day, 6 days a week. 4 Haulage of the SMC and poultry litter will be by way of articulated lorry and trailer. The trailers will have a capacity of 20-24 tonnes and will be fully covered.

A traffic management plan will be implemented to ensure that the lorries will only use the upgraded routes when delivering waste to the plant and on the return journey. This will provide the minimum disruption to the surrounding area.

Vermin Control Measures will be taken to prevent an infestation of rodents and other vectors. The most important of these will be the proper maintenance and operation of the receivinglstorage area. Fuel resulting from truck unloading operations will be swept into reception pits and doors to the fuet receipt and storage building will be kept closed when not in use. The perimeter of the site will be fenced and regular housekeeping will be taken to prevent the accumulation of waste that could attract vectors. Should such a problem develop, an extermination programme will be undertaken.

Road Cleansing A wheel wash will be installed at this site to ensure that all vehides leaving the site are clean. It is not envisaged that road cleansing will be required as part of this operation, but if it is deemed necessary once operation, measures can be put in place to prevent this nuisance.
