Project Description Location The boundary of the proposed TPP falls between latitude from 20o44’ 26.43” to 20o45’43.70” North and longitude from 70o 48’34.27” to 70o50’ 02.38” East. The nearest railway station Kodinar is 17 Km from the site by road. The nearest airport is at Diu at a distance of about 50 km by road from the project site. About 340 ha of land for the TPP and about 25 ha land for coal/water pipe corridor will be purchased through negotiations with the land owners. Entire plant site is outside CRZ limits. However, intake well, pumphouse, outfall and initial portion of coal conveyor pipes will be within CRZ limits. These activities are permitted in CRZ area as per CRZ Rules 2011. Application for relevant permissions is under process. Process The proposed TPP will comprise 2 x 660 MW boiler and turbines, with matching coal handling facilities; sea water intake and treated effluent outfall into sea, desalination plant, ash management system, and ancillary infrastructure and utilities. The power evacuation will be done through two numbers of 400 kV double

circuit lines. Each generator shall be connected to the 400 kV switchyard through its associated step-up Generator Transformer (GT). Supercritical technology has been selected for the boilers. This technology will facilitate higher efficiency around 41%. Air pollution load will be lower than the conventional technology. The firing system would employ latest low NOX burners. The proposed TPP will use imported coal with minimum gross calorific value 5000 Kcal/Kg and maximum sulphur content 0.7 %. Ash coneten in the coal will be less than 10 %. The annual coal requirement will be 4.5 Million Tons. The coal for the proposed TPP will be transported by closed pipe conveyor from the proposed port n e a r Chhara -Sarakhedi villages through dedicated coal-water pipeline corridor. Light diesel oil (LDO) for boiler start up and heavy fuel oil (HFO) for low load operation and flame stabilization will be used. The air emissions after passing through Electro Static Precipitator of efficiency 99.94% will be discharged through chimney of height 275 m. This will ensure high level dispersion of residual pollutants and will minimize addition to existing level of air pollutants. The proposed TPP will use sea water for meeting water requirements during operational phase. Total sea water requirement is estimated at 13,193 m3/hr. National Institute of Oceanography (NIO) and M/s Indomer Coastal Hydraulics Pvt Ltd have carried out modeling studies for deciding the water intake and effluent outfall points. They have recommended submerged type intake well of 10m diameter at water depth of -9.0 meter below Chart Datum. The location of intake point is at 20042’ 54” N: 70044’ 54.5” E about 585 meters inside the sea. Recommended outfall location is 20042’ 47.3” N 70045’ 46.3” E and at water depth of -8.0 to -8.5 meter below Chart Datum located on the Eastern side of the intake well. The distance between intake well and the outfall is 1500 meters. The bottom ash falling from the boiler furnace shall be conveyed to clinker grinders by means of scraper chain conveyor. Each bottom ash hopper outlet will be equipped with hydraulic operated hopper isolation gate. Hopper will have capacity to hold ash for four hours. At the discharge end of scrapper chain conveyor a clinker grinder will be provided. Bottom ash clinkers after crushing shall be transported continuously to the Bottom Ash slurry sump through slurry trenches. Flushing apparatus will be employed for coarse ash handling. From economizer hoppers coarse ash will flow to respective bottom ash slurry sump through pipe. Coarse ash slurry and bottom ash slurry will DRAFT FINAL REPORT

accumulate in slurry sump and will be further transported to the common dewatering bins through slurry pumping system. Economiser ash will be evacuated continuously. Two Intermediate surge Hopper will be provided for two boiler units. Fly ash from ESP hoppers will be conveyed pneumatically to the ash silos in dry form. It will be utilized as per rules. Unutilized fly ash will be disposed in ash pond as slurry form. Pollution Control Measures The Boilers will be provided with high efficiency electrostatic precipitators (ESP) to control particulate matter in flue gas to a maximum exit concentration of 50 mg/Nm3. Gaseous emissions shall be widely dispersed using 275 m tall stack. Coal yard will be provided with dust suppression system which would spray water on the coal piles. The Coal yard would have a drainage system to drain out rainwater & collect in a runoff pond. Dust extraction (bag filters) / suppression system at all coal transfer points, viz. crusher house, junction towers etc. will be provided. The oil from unloading and pumping areas and drainage will be recovered by recovery pump and sent back to the oil tanks. 3.0

Description of Environment Study for establishing status of baseline environment in area covering 10 km radial distance around project site was carried out during 1st March – 31st May 2010. Physical Environment The site is fairly plain topography having a natural gradient from west to east and sloping towards south (max 13 msl and min 2 msl contours at project site). The study area is characterized with brown soil, muddy clay, clayey and silty sand, Miliolite limestone and Gaj formations. The geological and lithological studies at site have been carried out by M.S. University, Baroda. The alluvium deposits were found to be of fairly recent age and only 5 to 20 m in thickness. Transmissibility and permeability of certain regions is fairly high due to the cavernous nature of the rocks present (mainly Miliolite limestone. The soils sampled from the area comprise 40% clay, 45% sand and balance silt. The CEC (cation exchange capacity) ranges from 0.011meq/100gm to 0.0272meq/100gm. The sodium content in soil is fairly

high with the sodium absorption ratio (SAR) varying from 0.7mg/kg to 2.81 mg/kg. The organic carbon content was found ranging from 0.92% to 1.78% by mass. Air and Noise Environment The climate of the area is hot and dry for most part of the year. Daytime temperatures are high which are cooled by the sea breeze during evening. The predominant wind direction is from NNW followed by WNW. Ambient air quality monitoring was carried out in the study area at six locations. PM10, PM2.5, SO2, NOx, O3, and mercury levels were analyzed and found to be below the National Ambient Air Quality Standards (NAAQS), 2009. Mercury and Arsenic was not detected in any of the samples. The ambient noise levels in the six villages were found to be within the acceptable limits (residential area). The average noise level for day time is ranges between 48 dB (A) and 50 dB(A) whereas the nighttime average noise level ranges from 39 dB(A) to 42 dB(A). Water Environment Singhwadi River, Somat and Rupan Nadi are the three streams present in the study area. The streams do not pass through the project site. M/s Indomer Coastal Hydraulics (P) Limited, Chennai has carried out marine environmental impact assessment. In seawater the observed pH ranges from 8.10 - 8.24. Rest of the parameters did not show much variation and were found to be within normal range. The BOD and COD levels indicate a fairly well mixed water column at the coast. Heavy metals like Cadmium, Mercury, Lead and Chromium levels are well below the permissible limit. Presence of phenolic compounds and petroleum hydrocarbons were also found to be within the permissible limit. The groundwater in the area is accessed mainly through about 50 open wells.

scrubs 5.77%, rivers 4.70% and sparse vegetation 3.26% on mud flats, 2.38% in sandy areas, 2.10% within habituated area. Biological Environment The study area consists of tropical dry deciduous, northern tropical thorn & littoral and swamp forests. Four Reserve Forests and five patches of unclassified forests are present in the study area. The nearest reserved forest is located 1.5 km from the project site at Nanawada. Primary flora survey of the area was conducted in the vicinity of the Nanawada and Kaj villages. Shrubs are the dominant perennial species of this area, represented mainly by Ganda Baval (Prosopis juliflora), Aakado (Calotropis procera & Calotropis gigantea), Chani Bor (Zizyphus nummularia), Ketki (Agave americana), Fafdo Thor (Opuntia sp), Thor (Euphorbia nivulia) Kerdo (Capparis deciduas) and Lantana (Lantana camara). Study of the fauna in the area revealed that many migratory bird species frequented this area during winter season. Kaj - Nanavada wetland is located near the site, which has come into existence due to natural delta formation and construction of earthen bund to store fresh river water. During winter season, resident and migratory birds like Seagulls, Pelican, Flamingo, etc. visit this place. This wetland also serves as a source of irrigation for the villagers. Greater Spotted Eagle (Aquila clanga) and Eastern Imperial Eagle (Aquila heliacal) are two vulnerable species present in this area. Marine biodiversity study of the area also shows good primary and secondary productivity comprising adequate phytoplankton primary productivity, zooplankton and other species diversity. Among fishes, commercially important species like Ophisthopterus tardoore, Arius sp., Cynoglossus sp., Lutjanus sp., Johnius sp., and Epinephelus sp were found. Villages of Velan, Madhwad, Kotada, Kob primarily depended on fishing for their livelihood. Socio-economic & Cultural Environment The literacy rate of study area is 59.9%. Gender ratio is 0.99. The variation in the percentage of SC population in the area is quite high with the minimum of 0% to a maximum of 81.5% (in Nanawada village). On the other hand, the ST population is mostly less than 2%, with an exception of 6.2% at Fafni Nani (population-wise the smallest village) alone. More than 75% of the population residing in the region depends on agriculture for livelihood. DRAFT FINAL REPORT

Anticipated Environmental Impacts and Mitigation Measures Air Quality Construction phase will generate fugitive dust emission which will be controlled by water sprinking. The proposed TPP will have only one stack with two flues. Imported coal will contain maximum sulphur content of 0.7% and maximum ash content of 10%. The maximum coal consumption rate for 1320 MW plant is 511 TPH. The stack height will be 275 m . ISCST3 model has been used to predict the air pollution impacts from proposed project with respect to SO2, NOx and PM. Maximum 24 hourly incremental GLC of PM has been predicted as 0.96 µg/m3 at about 3.0 km downwind distance. The maximum 24 hourly incremental concentration of SO2 and NOx is predicted as 28.12 µg/m3 and 12.47 µg/m3 respectively. The maximum GLC would occur at about 3-4 km downwind distance in east / south east direction. It has been ensured that during the plant operation the ambient air quality would remain well within the prescribed NAAQS for residential, rural and other areas. Noise Environment Use of heavy plant and machinery will result in noise. The construction activities are scheduled to complete in 44 months. The noise impacts during construction phase are temporary. The noise impact would be localized to construction workers during their duty hours. These will be mitigated to through use of personal protective equipment (PPEs) like ear muffs/plugs etc. During operation phase, the stationary noise sources are Boilers, Steam Turbine generators, Compressors, Pumps, Coal crushers etc. and mobile sources like vehicular traffic. The noise generation at source from major equipment will be restricted to 85 dB(A) through purchase specifications. The cumulative noise impact has been predicted and the impact of noise outside the proposed project premises would be insignificant. The incremental noise level at the nearest village Nanawada located about 1.5km will be less than 1 dB(A). The noise levels would remain within the prescribed ambient noise standard for residential area. The occupational noise exposure to the workers will be maintained well within the prescribed OSHA standard limits / Factories Act by providing noise proof duty cabins, acoustically treated TG building and also by using ear plugs.

Water Environment The estimated total seawater requirement for proposed 1320 MW TPP is 13193 m3/h. The major part of the total seawater will be utilized for cooling water makeup. Desalination plant based on reverse osmosis (RO) system shall be installed to produce 1885 m3/h desalinated water for feed to DM plant, service water, air conditioning purposes, fire water make-up, coal and ash handling system, potable use and for greenbelt development. The cooling tower blow-down (7660 m3/hr) and Reverse Osmosis reject (1225 m3/hr) will be disposed to the sea. The proposed re-circulating / closed condenser cooling system using sea water and natural draft cooling towers would prevent thermal impact on receiving water body. Nonchromate / poly phosphate based shall be use as anti fouling / scaling reagents will be used in cooling water system. No Groundwater will be used in operation of the proposed project. The proposed spread channel will contribute to groundwater recharge in the area through seepage . Land Environment The proposed site is on coastal flat terrain wherein most of the land is agriculture but non-forest. The environmental pollution impacts during construction phase would be temporary and are expected to gradually become zereo by the time of commissioning of proposed project. During operation phase, total ash generation has been estimated as 51.08 TPH (1,226 TPD), out of which fly ash (80%) would be 40.86TPH (981TPD) and bottom ash (20%) would be 10TPH ( 245TPD). It is proposed to collect dry fly ash from ESP hoppers in dry form and supplied to ash users. The balance unutilized ash (mostly bottom ash and some fly ash) will be disposed in ash disposal pond. The ash pond will be provided with HDPE lining to prevent any chance of leaching. Spent oils, lubricants and oily sludges will be sold to the potential users after obtaining authorization from GPCB. Sludge will be generated from seawater clarification, effluent and sewage treatment plant. The sludge will be dried in thickener/ centrifuge and then in sludge drying beds, It will be finally disposed in ash pond. Commercial garbage generation will be less than 1 TPD. It will be sorted for recyclable, inert and biodegradabale waste. Recyclable waste will be sold to kabadis. Inert waste will be used as landfill material. Biodegradable waste will be composted. 33% land area will be developed as greenbelt. Locally available plant species will be used as greenbelt. DRAFT FINAL REPORT

Additional Studies Social Impact Assessment The 10 km radial distance impact zone of the proposed project falls in two talukas namely Kodinar and Una of Junagarh district, Gujarat. The nearest villages to the proposed TPP are Nanawada, Kaj and Jantrakhadi, all in Kodinar Taluka. Primary survey of social, infrastructure and economic structure of the study area was conducted by undertaking field surveys. Public meeting was organized in Nanawada and Kaj villages. Out of total 340 ha of land, about 331 ha private agricultural land and 9 ha government land is being purchased by the SPEGPL. No residential areas will be disturbed due to the proposed site. SPEGPL has allocated 0.4% of the total project cost [Rs. 73350 crores ] for various CSR activities. Risk Assessment Even though risks from the proposed TPP are not significant, with a view to develop worst case scenario scientific risk assessment has been carried out. Fire and Explosion hazards are computed for different fuel storage and handling facilities at proposed project. As per the criteria, the LDO and HFO storage and handling facilities at proposed project fall in light category of degree of hazards. The accidental release of LDO and HFO from the storage facilities have been studied by building various probable scenarios on the basis of their properties and the effects. The worst possible scenarios are then calculated in terms of damage distances. The results (damage contours) are plotted on proposed plot plan in order to visualize magnitude and extent of consequence. The consequence analysis results indicate that the maximum distance for 4 kW/m2 thermal radiation is 73.1 m under stability class D (3 m/s). The 4 kW/m2 thermal radiation will cause first degree burn for 10 sec. exposure to people within the plant premises. There will not be any risk to people outside the plant area. Release of LDO/HFO due to leak in storage tanks may lead to formation of a pool and depending on availability of ignition source may cause pool fire. This scenario was visualized by considering different leak sizes of 25 mm and 50 mm and catastrophic rupture of storage tank for various heat loads 37.5 kW/m², 12.5 kW/m² and 4.0 kW/m² under the weather stability conditions of 2F, 3D and 5D. The damage distances due to catastrophic rupture of LDO storage tank for the heat load of 4.0 kW/m² are predicted as

) Sea water after processing in RO plant can be used for boiler water, service water, and as potable water ) Proximity to the proposed port at Chhara – Sarakhadi villages located at the distance of approximately 5 km from the proposed power plant site facilitates transportation of imported coal from the port to the power plant site through pipe conveyor ) Ease of power evacuation ) Transportation of heavy equipment from Pipavav port to power plant site. 2.2

Process Selection A supercritical, reheat steam cycle with regenerative feed heating arrangement is envisaged for the proposed plant. Salient Features of Super Critical Technology are: ) Super Critical steam pressure is above 22.1 (MPa) at which steam and water do not have distinct separate phases. The cycle medium (steam) is single phase fluid with homogenous properties. ) The Super Critical steam pressures and temperatures result in better thermodynamic performance and improved cycle thermal efficiency. The typical boiler superheater pressure and temperature are 250 bar and 570O C with reheated steam temperature of 570O C. The Super Critical units can achieve 3-4% more thermal efficiency than sub critical units in 500 / 600 MW. ) The modern sub-critical cycles have attained efficiencies close to 37%. Further higher efficiency can be achieved by using super-critical steam conditions which is around 41%. ) Faster start-up time is achieved in case of super-critical units. Worldwide more than 400 super-critical plants are in operation. ) Use of super-critical units results in lower emission levels. 1% increase in efficiency reduces 2% specific emission such as CO2, NOx, SOx and particulate matters. The reduced coal consumption results in lower ash generation for the same amount of power generation. ) The boiler tube size is smaller in case of super critical units, which puts a limitation regarding the performance with high ash containing coal (typical Indian coal). Use of imported coal avoids this problem. ) Purity of feed and boiler water is a major requirement in super critical units. Problems experienced in the past were largely due to the use of

deoxygenated all volatile (AVT) cycle water chemistry. The solution to these problems is the combination of a condensate polishing plant with oxygenated treatment (OT) which is a proven procedure. ) The super-critical units use once through boilers without requiring boiler blow down system. This has positive effect on water balance of the plant with less condensate needing to be fed into the water-steam cycle and less water to be disposed off. ) Specific installation cost i.e. the cost/ MW decreases with increased plant size. The specific Installation cost is 5% higher than that for sub critical plants. Operating cost due to fuel is lower due to the increased thermal efficiency. Process flow diagram for the proposed plant is presented in Figure 2.5 and salient features of the proposed plant are presented in Table 2.1.

Fuel Oil System The Fuel oil system will be provided for: a)

Boiler start-up

b) Flame stabilization during low load operation with or without coal firing. Two types of fuel oils are envisaged for use in the proposed 1320 MW unit: (a) light diesel oil (LDO) (for Boiler Start up) and (b) heavy fuel oil (HFO) for low load operation and flame stabilization, as necessary. In addition to these, HFO may also be required during mill cutting in and mill cutting out operation. HFO and LDO will be unloaded from road tankers. There will be 2 x 100% (1W and 1S) LDO unloading pumps for unloading from road tankers. LDO will be stored in one 1000kl capacity storage tank. LDO will be pumped by pressurizing pumps from the storage tank to the boiler for start up. There will be 2 x 100% (1W and 1S) HFO unloading pumps for unloading from road tankers. HFO will be stored in two (2) numbers storage tanks each of capacity 2000kl. HFO will be pumped by pressurizing pumps from the storage tank to the boiler for low load operation and flame stabilisation. From the storage tanks, HFO will be delivered to the respective day tanks located near the main plant by means of the pressuring pumps with necessary piping interconnections. Two (2) HFO day tanks, each of 500 kl will be installed. These pressurizing and heating units for the proposed station will be accommodated in the fuel oil pressurizing pump house.

Plant Water System The consumptive water requirement of the plant will be made available from sea through GRP/MS pipe lines and pump house installed near sea coast. Total sea water requirement of the proposed plant is estimated as 13,193 m3/hr. The break-up of water requirement and water balance are discussed in chapter 4 of this report. Intake well (Refer Figure 2.7) is proposed at water depth of -9.0 meter below Chart Datum. Intake well is proposed to be submerged type intake well. The location is about 585 meters inside the sea within the port area which is sheltered by the proposed breakwater of 1500 m length. Submerged intake will be of 10 meter diameter. Pipe line will be laid from the submerged well to the shore based pumping station with necessary armour cover. Heavy duty grill be provide at top of submerged well to prevent objects following into the well. Outfall is proposed in the water depth of -8.0 to -8.5 meter below Chart Datum located on the Eastern side of the intake well. The distance between intake well and the outfall is kept at 1500 meters (Refer Figure 2.4). The sea water will be clarified for the use in condenser cooling circuit in a closed cycle circulating cooling system with wet type natural draft cooling towers. A part of the sea water will be used to feed the desalination plant located inside the main plant boundary. The desalinated water will meet the miscellaneous water demand for the power plant. Ultra-filtration (UF) as pretreatment will ensure entering water quality of SWRO (Sea Water Reverse Osmosis) achieving SDI (Silt Density Index)
