EXECUTIVE SUMMARY INTRODUCTION Bengal Concessions Private Limited (BCPL), a subsidiary of HE Terminals Private Limited (HETPL) is planning to set up an LNG Storage and Regasification terminal at Kukrahati, East Medinipur District, West Bengal. BCPL intends to develop a small scale LNG Regasification project at the proposed site at Kukrahati with an initial regasification capacity of 1.5-3.0 MMTPA, which will be expanded up to 5 MMTPA in future. During this operational period, LNG Carriers of ~30,000 m3 each are planned to be berthed at two riverine jetties which are planned to be constructed at a distance of ~150m from the shore. LNG carriers of ~30,000 m3 will bring the LNG about 2-3 times a week for regasification initially and upto once daily at peak capacity. Multiple pipelines are envisaged to emanate from the site to deliver Re-gasified LNG (RLNG) to the end users. Also, a truck loading facility shall be constructed to deliver LNG to nearby customers. The proposed project requires Environmental Clearance (EC) from Ministry of Environment, Forest and Climate Change (MoEFCC). BCPL has received an approved Terms of Reference (ToR) from MoEFCC on 16th November 2017 and TOR was amended at MOM of the EAC (Ind-2) meeting held during 24-26 Sep-2018. M/s ERM India Pvt Ltd. has been engaged by BCPL for conducting EIA study and to support in obtaining environmental clearance (EC). ERM’s NABET Certificate No. NABET/EIA/1619/ RA 0055 was issued on June 21, 2017 and is valid up to October 31, 2019. Location & Accessibility The proposed site is located in village Matiramchak; Kukrahati Panchayat, District: East Medinipur, West Bengal. The site is located in the Survey of India Toposheet No. F45K4. The site can be accessed from NH 6 via. Kolaghat- Haldia road (NH 41) and from NH 41 to Chaitanyapur via. Balughata road. From Kukrahati, the site can be accessed by Geonkhali- Kukrahati road, which traverses adjacent to the site. The nearest Railway Station is Bajitpur, 4.5 km from the site. The nearest Airport of Netaji Subhas Chandra Bose, Kolkata is approximately 140 km from site. PROJECT DESCRIPTION Resource Requirement Land: The land for the project is ~50 acres. However, some portion of the land fall within the high-tide line of the Hooghly River. Hence, the available land for the proposed project is ~48 acres which has a 900m long waterfront on the River Hooghly. Currently 37 acres of land at ERM EIA STUDY FOR LNG TERMINAL AT KUKRAHATI PROJECT #0419831 NOVEMBER 2018 1 Kukrahati is under a lease with M/s Euclix Shipbuilders Private Limited awarded by the Haldia Development Authority (HDA). The lease is being transferred to BCPL for developing the LNG Regasification Terminal. In addition, 11.5 acre of land is under brick kiln and is private land and same shall be procured from the land owners. Water: Approximately, 50 KLD river water will be required during peak construction period to meet the demand for construction activities etc. Water would be sourced from the Hooghly River. Fresh water will be required for meeting the domestic water needs of personnel working at the terminal. The requirement of domestic (potable) water has been estimated at 2-3 KLD. It will be supplied through approved supplier. Power: Maximum 2 MW power would be required for construction phase and will be sourced from DG set. Power requirement during operational phase will be approximately 23 MW. The power will be sourced from the West Bengal State Electricity Board (WBSEB). However, in emergency, Gas turbines of 2 x 11.5 MW capacity will be provided as back up and 2 x 500 KW DG sets for the auxiliary equipment. Manpower: Approximately 200 workers would be required during the peak construction period, most of whom would be unskilled workers. The operation of the facility post- construction will require up to 45 - 60 full time employees for all working shifts. Operational Activity LNG will be imported via LNG Carriers and will be stored, re-gasified through re-gasifiers on the land and the RLNG will be sent to customers through evacuation pipelines. LNG Offloading: LNG offloading will be carried out by hard/soft unloading arms. LNG Storage: Total LNG storage capacity within the project site would be 90,000 m3 (including 30,000 m3 for future) onshore storage tanks shall be maintained at -163ᵒC to store and handle the LNG. LNG Reloading: LNG may be reloaded into suitably sized LNG Carriers in case of emergency or to be further used as bunkering fuel. Provisions shall also be there at the jetty to re-load LNG directly into LNG fuelled ships. LNG Regasification: Onshore Regas Unit will be provided with ambient air based Intermediate Fluid Vaporizers (IFVs). High pressure LNG booster pumps will be provided in the Re- gasification area for feeding LNG to the Vaporiser to the expected send out pressure (approximately 90 barg). ERM EIA STUDY FOR LNG TERMINAL AT KUKRAHATI PROJECT #0419831 NOVEMBER 2018 2 BOG Handling and Fuel Gas System: The boil off gas produced both by natural cargo heating and by operations will be handled by the BOG handling system. The BOG handling system will manage the BOG production in two ways: Providing fuel gas to the fuel gas header; Sending the BOG to the Re-condenser for re-condensation BOG to BOG compressor for pumping into the NG outlet header Venting System: The LNG terminal shall be constructed with no venting philosophy under normal operations. However, the terminal will have the venting/flare system which in case of emergency will aim to discharge/burn any flammable vapour release to atmosphere at a safe location, thus minimizing any potential risk to involved personnel and plant. Metering Station: The metering station, equipped with custody transfer meters, shall be implemented with several metering lines in parallel each one having one ultra-sonic type flow meter. LNG Truck Loading Station An LNG truck loading station shall be implemented consisting of 4 to 10 truck loading bays having common weighbridge; Each loading bay shall be designed to export 50 m³/h LNG; and The total BOG from the LNG truck loading station (4 bays) will be designed at 3,000 m³ (n)/h. There shall be a provision to increase the number of truck loading bays in the future if so warranted by the demand. Pollution Sources: Pollution sources from the LNG terminal will be air & noise emission, wastewater generation, and solid and hazardous waste. Air emission: The potential air emission from the construction activities are as follows: Fugitive dust emission due to earth work and construction material handling; Emission from DG sets and diesel operated machineries and equipment The potential air emission from the operational activities are as follows: Back-up Gas generator (2 x 11.5 MW) and DG sets (2x 500 MW) Emergency flaring system; Waste Water: Wastewater generated from the construction site is as follows: Wash water from washing of construction equipment & machineries and same will be treated through sedimentation tank & oil & water separator. Sewage from construction camp - the domestic waste water will be treated through septic tank and soak pit ERM EIA STUDY FOR LNG TERMINAL AT KUKRAHATI PROJECT #0419831 NOVEMBER 2018 3 Solid Waste & Hazardous Waste: On a regular basis, there will be no generation of any non-hazardous or inert solid waste from the proposed LNG terminal. A small quantity i.e. about 0.5 KL/year of hazardous oily waste will be generated during periodic maintenance. The hazardous waste likely to be generated from the terminal are: Waste oil from back up DG sets; Rags and filter materials; Packages / Containers having hazardous waste residues (i.e. drums for oil and diesel). Noise Emissions The main noise emission sources in LNG facilities include pumps, compressors, generators and their drivers, compressor suction / discharge, recycle piping, air dryers, heaters, air coolers at liquefaction facilities, vaporizers used during regasification, and general loading and unloading operations of LNG carriers /vessels. BASELINE ENVIRONMENTAL STUDIES An area of 10 km from the boundary of the proposed project site has been considered for the baseline studies. The baseline data obtained has been obtained through primary monitoring/survey and review of secondary information has been summarized below: Land Use: The predominant land use- land cover of the study area includes agriculture (65.97%), River (19.04%), Settlement (14.12%), Brick Kiln (0.34%), Water Treatment Plant (0.21%), Road Network (0.15%), Waterbody (0.14%) and Railway Track (0.03%). Soil Quality: The soil samples were collected from five locations in the study area. The pH level in soil sample was 6.66 to 7.82. Available nitrogen, phosphorus and potassium contents varied between 70-189 mg/kg; <3-4 mg/kg and 82-278 mg/kg respectively. Also soil quality does not indicate contamination from any external source. Natural Hazards: Study area lies in Zone III, the moderate severe seismic zone. The district level cyclone prone block map indicates that the proposed site is not falling in the cyclone prone area. The project site though situated along Hooghly River does not lie in Flood Prone Block in District Disaster Management Plan. Ambient Air Quality: Monitoring of air quality was conducted at 8 monitoring locations in the study area during post-monsoon season. The monitored average PM10 concentration varied from 60.83 to 66.45 µg/m3. The monitored average PM2.5 concentration varied from 35.00 to 40.05 µg/m3. Also all other air quality parameters (SO2, NO2, CO, etc.) monitored in the study area were found below the National Ambient Air Quality Standards (NAAQS).
