The undersigned is directed to refer to letter dated 19.03.2010 alongwith copies of EIA/EMP, public hearing and Marine Impact Assessment Study reports 16.04.2010 on the subject mentioned above and subsequent communication dated 29.04.2010 seeking environmental clearance under the provisions of EIA Notification, 2006.


2.         The Ministry of Environment & Forests has examined the application.  It has been noted that the proposal is for setting up of 2x600 MW and 3x800 MW Imported Coal Based TPP at villages Kottatai, Ariyagoshti, Villianallur & Silambimangalam, in Chidambaram Taluk, Cuddalore District, Tamil Nadu. The land requirement will be 1181 acres. Cooling water requirement will be obtained from the Bay of Bengal by gravity through pipe line and further pumped through a seawater intake pumping system. Proposed cooling towers would operate with 1.3 Cycles of Concentration (COC). The blow down would be discharged deeper into the sea through a 1.5 km long marine diffuser. A 30 MLD desalination plant is proposed to meet fresh water demand. Reverse Osmosis (RO) rejects will be disposed through the same marine diffuser. The site elevation will be leveled to +2.2 m above the Mean Sea Level. The sulphur and ash content will be 0.2% Maximum and 6% respectively.  Imported Coal from Indonesia will be used. River Vellar is located at a distance of 1.5 km   from the southern boundary of the proposed site. CRZ demarcation has been done by NIO, Visakhapatnam.  Pichvaram mangroves are located at 8.0 km from the southern boundary of the proposed site. Public hearing was held out for 3600 MW on 05.02.2010.

Sub:   2x600 MW + 3x800 MW Coal Based TPP at Villages Kottatai, Ariyagosthi, Villianallur & Silambimangalam, in Chidambaram Taluk, in Cuddalore, District, in Tamil Nadu by M/s IL & FS Tamilnadu Power Company Limited - reg. Environmental Clearance.


            The note from page7- 8 N / ante may kindly be referred.


M/s IL & FS Tamilnadu Power Company Limited have submitted a proposal for environmental clearance for 2x600 MW + 3 x 800 MW Coal based Thermal Power Project in District Cuddalore in Tamilnadu. As per further clarification provided by CPCB regarding critically polluted industrial areas/ clusters, the proposed project does not fall in the above potential impact zones. SIPCOT Industrial Complex, Phase I & II in Cuddalore in Tamilnadu have been identified as critically polluted industrial areas.


2.         The company has firmed up the coal linkage for 3600 MW capacity with M/s PT Talen ECO Coal, Indonesia for supply of coal.


3.         The Expert Appraisal Committee – (Thermal) has recommended the project for environmental clearance in its meeting held in 30th April-1st May, 2010. Further, it is noted that the project location is 500 m away from HTL and 100 m from the Buckingham Canal in the western side of the plant area.  This has been brought in the Environmental clearance. As per the CRZ map (F/x) prepared by NIO, Goa which is one of the authorized agencies, it is noted that on the western side of the plant area, Buckingham Canal is almost touching the plot area at some locations even though a distance of 100 m as per the provisions of the  CRZ notification is reported to be maintained.  Therefore we may stipulate a condition that “distance from the Buckingham Canal shall not be less than 150 m. Building and permanent structures on the western side of the canal shall be designed accordingly. Further, we may stipulate specific condition regarding prior CRZ clearance for the activities / facilities to be located in the CRZ area shall be obtained”.


4.         In view of the above, environmental clearance may be accorded to the project subject to stipulation of specific safeguards. The specific conditions (no. i & ii) regarding CRZ are also included in the Draft Environmental clearance placed below for approval please.
