Location map is given as Figure FD0101. GMR Energy Limited (GEL) has been operating three power plants i.e. 220 MW barge mounted power plant at Kakinada Port and 1138 MW gas based power plants at Vemagiri. Proposed LNG facility will cater gas requirements of the power plants to operate at optimum plant load. Additionally, it is envisaged that other existing and upcoming power plants and other industries/consumers would also benefit from the proposed LNG facility at KDWP. The proposed LNG facility is attracting the EIA notification, 2006 and CRZ notification, 2011 (as amended) and GHPL appointed NABET accredited L&T Infrastructure Engineering Limited (L&TIEL) as Environmental Consultant for conducting Environmental Impact Assessment (EIA) Study. 2 Details of the Project The LNG facility with a capacity of 1.75 MTPA is proposed to be developed at Berth No. 7 of KDWP. Berth No. 7 is already constructed and facilities required for LNG import need to be developed. At the ToR stage, two locations for regasification facility are being examined. o Location 1: The first location being examined is setting up regasification facility in the backup area available behind Berth No. 7. o Location 2: The second location being examined is setting up the regasification facility within the available land of GMR barge mounted power plant located at ~1.5 km from Berth No. 7. The proposed LNG facility consists of the following: Development of necessary facilities/equipment for ship berthing and mooring, LNG unloading arms with all safety measures LNG Storage and transportation LNG Regasification Facility Pipeline for connectivity to existing gas distribution grid The Pre - Feasibility report for the development of the project details is enclosed as standalone document. 3 Methodology Methodology to carry out the EIA study involves the following stages: Reconnaissance survey and site visit Review of available literature 1 Introduction to Project Page 1

6 Compliance to statutory requirements Baseline environmental monitoring Identification and Prediction of Impacts Risk Analysis and Disaster Management Plan Environmental Management Plan 4 Baseline Environmental Monitoring The baseline environmental studies will be carried out for Terrestrial and Marine environments. The study will be a combination of primary (field surveys) and secondary data collection. Study Period: The study period is Summer Season of the year 2016 and will be carried out after successful online submission and registration of the application. Study Area: An area covering 15.0 km around the Berth No. 7 area and from the regasification facility is earmarked as study area of the project. A map showing the study area is enclosed as Figure FD Marine Environment The baseline marine environmental surveys near coastal area of project site will be studied through field studies covering one (01) season data collection (One Time Sampling). Marine environment in the region will be assessed through field studies and compilation of secondary data and literature surveys. Marine environmental studies will be undertaken at identified locations which will cover water quality, sediment quality, biological aspects/ marine ecology (plankton and benthos, marine fauna), fishing & breeding grounds and fishery resources, if any. A reputed marine environmental monitoring agency will be appointed for carrying out marine monitoring studies. A map showing sampling locations is enclosed as Figure FD0103. Marine Water Quality Surface and subsurface samples will be collected using NISKIN Sampler. Some of the physical parameters such as Temperature, ph, Salinity and Transparency will be observed on-site. Samples will be preserved for assessing other physico-chemical and bacteriological parameters. Methodologies used for collecting, preserving and analysing water samples will be as per standard protocols and procedures defined in standard manuals and reference material. Parameters that will be assessed are listed below: Physico-chemical parameters: ph, temperature, salinity, turbidity, conductivity, suspended solids, total dissolved solids, DO, BOD, COD, chloride, sulphate, sodium, potassium, silicate, oil and grease. Nutrients: nitrite, nitrate, ammonia, total nitrogen, total phosphates, sulphide Heavy Metals Bacteriological parameters: Total Coliforms, Faecal Coliforms. Sediment Quality Sediment samples will be collected using a suitable grab (Naturalist s Grab / Van Veen Grab). After collection, samples will be sieved and subjected to physico-chemical analysis. Parameters that will be assessed include composition, texture, organic matter and heavy metals. 4 Baseline Environmental Monitoring Page 2

7 Biological Aspects Biological parameters viz., phytoplankton, zooplankton, chlorophyll-a, pigments and primary productivity will also be assessed. Plankton content in coastal waters will be assessed through collection of water samples using Plankton net of suitable mesh size. All net hauls will be fixed in buffered 5% Formaldehyde and stored for analysis in Laboratory. In addition, samples collected with NISKIN sampler will be fixed in Lugol s iodine for quantitative enumeration. Quantitative enumeration will be done using a Sedgewick Rafter counting chamber following standard protocols (UNESCO, 1978). A research microscope will be used for taxonomic identification. Primary Productivity will be measured following light and dark bottle method (Gaarder and Gran, 1927, re-described Subba Rao, 2002). Benthic Communities Sediment samples collected for assessing physico-chemical characteristics will be used for enumerating benthic communities. Sediment samples intended for benthic communities assessment will be preserved with Rose Bengal and Formalin Solutions. Analysis of benthic communities will be including meio and macro benthos in the region. 4.2 Terrestrial Environment Inland Water Quality The study area will be inventoried to identify the sources of water i.e. both surface and groundwater sources. Water samples will be collected at the identified sources based on the type of the source, its relevance, number of upstream and downstream users and the type of the industrial activity in the vicinity. Water quality will be monitored at Six (06) locations within the study area. Representative water samples will be collected and analysed, once during season, for physico-chemical and biological characteristics. Water Quality will be monitored adopting procedures as per IS 3026 and relevant guidelines of MoEF&CC/CPCB. A map showing monitoring locations is enclosed as Figure FD0103. Meteorology Meteorological parameters such as wind speed, direction, relative humidity, rainfall, temperature etc., will be recorded by using automatic weather monitoring station in the study area at One (1) location during the summer season. In addition, the general meteorological data from Climatological Tables of India Meteorological Department (IMD) shall be used to establish the baseline meteorological conditions of the site. Ambient Air Quality The ambient air quality monitoring will be carried out as per CPCB/MoEF guidelines. The locations will be identified with regard to the predominant wind direction, topography, population, sensitive locations and possible impact zones. Representative Ambient Air Quality (AAQ) will be monitored at Six (06) locations in the study area. In order to complete the monitoring before onset of monsoon season, it is proposed to increase the frequency of ambient air monitoring to four times a week and collect desired 24 samples within Six Weeks in Summer Season. Two LNG terminals proposed at Kakinada have completed the EIA studies and baseline data of the terminals are also available in public domain. Therefore it is proposed to substantiate the primary data generated with available secondary data. As per MoEF&CC National Ambient Air Quality Standards (NAAQS) Notification dated 16 th November, 2009, all twelve (12) parameters will be monitored. The measurement will be 4 Baseline Environmental Monitoring Page 3

A map showing monitoring locations is enclosed as Figure FD0104. Ambient Noise Levels Noise levels will be measured at Six (06) locations within the study area. The representative intensity of the noise levels (Peak noise and Equivalent noise levels) will be measured at hourly intervals for 24 hours once during the study period. Representative noise level measurement being carried out as per the IS: as adopted by CPCB, CPCB/IS: and the CPCB/ OSHA Standards using a precision noise/sound level meter. A map showing monitoring locations is enclosed as Figure FD0104. Soil Quality/Land Environment The soil types in the study area will be identified based on the review of the available data supported with information gathered from reconnaissance survey. Representative soil samples will be collected at Six (06) locations for various types of soils in the study area. The collected samples will be analysed once during season for physico-chemical characteristics. A map showing soil sampling locations is enclosed as Figure FD0104. Land use around 10 km radius of project site will be established based on latest satellite imagery (LISS III or IV based on availability). Terrestrial Ecology Vegetation pattern will be identified based on literature survey and field investigation. A list of flora and fauna of terrestrial ecosystem will be prepared. Endangered and dominant plant species area will be identified. Flora and fauna in project area will be assessed through field observations and also information collected from secondary sources. Flora and Fauna: Flora and fauna in study area will be assessed by primary surveys and collecting secondary information from sources like Forest Department and other agencies involved in similar studies. Floral Diversity and Species Inventory Sampling of vegetation will be done using selected samples of 100 m x 10 m belt transects for tree species, 10 m x 10 m quadrates for shrub species and 1 m x 1 m quadrates for herb species. Faunal Diversity and Species Inventory (Vertebrates) Inventory of animal species will be prepared based on following methodology: Direct observation during field visits Interviewing local villagers and forest officials Secondary sources such as published literature on fauna. Bio-diversity index and relative abundance index of different types of flora will be established. Canopy cover of trees in different areas will also be established. Terrestrial flora and fauna survey will be carried out as per standard practice. The number of trees to be felled for the project will be estimated and eco-sensitive areas within 10 km and 15 km radius from the project boundary will be identified. 4.3 Demography and Socio-economics The socio-economic conditions in study area will be established through collection and review of available secondary/ published data and socio-economic data. This will include 4 Baseline Environmental Monitoring Page 4

9 Demographic structure covering total households, total population, population density, sex ratio, schedule caste and schedule tribe, literacy and employment. Cultural and aesthetic attributes in study area including places of historical and archaeological importance Inventory of places of historical, cultural and religious importance in the study area. Details of various economic activities, industries, fishermen details and fishing hamlets if any, shall be collected Demographic details and other socio-economic details will be collected based on the latest census documents and recently published District Statistical Hand Book 4.4 Establishment of Baseline Environmental Conditions The information collected from secondary/published data of project region and primary surveys will be used for presenting the baseline environmental and social conditions. The baseline levels will be compared with the existing standards prescribed by the MoEF&CC/CPCB or APPCB. Any critical issues in the baseline environmental conditions will be identified and adequately addressed in the EIA report. 5 Anticipated Environmental & Social Impacts and their Mitigation Measures Environmental attributes likely to be affected by project activities will be identified and impacts will be assessed. Project activities can be broadly classified into construction and operation phase activities. Most appropriate and accepted methods will be used to quantify impacts likely to arise due to proposed development. The mitigation measures proposed to minimise/avoid each of the likely impacts that occur during construction and operation phases will be discussed. 5.1 Marine Environment Impacts on marine ecology will be studied for construction and operation phases of the proposed project. Based on development plan of the proposed facility, impacts will be identified and predicted for construction and operation phases. Impact on marine environment including water quality, sediment and ecology will be studied with respect to the following project activities: Construction Phase Construction of breasting/mooring dolphins Dredging and disposal of dredged material Construction of LNG storage and regasification facility Laying of pipelines etc. Operational Phase Vessel movement LNG unloading, storage and transportation Regasification and transportation of RLNG Appropriate available mathematical models will be used to quantify the impacts due to dredge spoil disposal, hydrodynamics in and around the facility etc. 5 Anticipated Environmental & Social Impacts and their Mitigation Measures Page 5

10 5.2 Air Environment The construction phase will involve movement of construction materials to the project area, site clearing, vehicular emissions, emissions from the construction machinery, etc. which in turn could influence the ambient air quality in the region through build-up of dust levels and gaseous emission levels. The build-up of pollutants in the ambient air during the construction phase is temporary in nature and will be localised. Impact on air environment during operation phase is envisaged in terms of emissions from power generation using boil off gas. These might result in increased levels of NO X. Build-up of pollutant levels due to these emissions will be arrived through modelling studies using Gaussian Dispersion Models (ISCST3/AERMOD). Mitigation measures will be accordingly suggested. In case DG sets are likely to be used during construction and operation phase of the project, emissions from DG sets which are likely impact the air quality will be presented. 5.3 Noise Generally, the activities which tend to impact the air environment also equally impact the noise levels. The impacts on the noise levels during the construction phase could arise from vehicular traffic, construction machinery, DG sets and transportation of construction material to the site. Further, during the operation phase, noise might be generated due to LNG handling operations, transport of LNG through tankers, DG sets and vehicular traffic and the same will be felt upon the work personnel and nearby settlements. Impacts will be evaluated qualitatively taking into consideration the noise generating sources together with environmental conditions and the receptors in the project influence area. Suitable mitigation measures shall be suggested in the EMP. 5.4 Water Environment The source of water requirement vis-à-vis waste water to be generated along with treatment facilities, use of treated waste water along with water balance chart taking into account all forms of water use and management will be presented. Runoffs containing contaminated water during construction and operational phases of project can affect the water environment. Impacts on the drainage of the area and its surrounding will be studied. Rainwater harvesting, water conservation measures and possibility of zero discharge options will be studied. 5.5 Land Environment The impacts on the land environment during the construction and operation phase shall be disposal of construction materials and change in land use patterns. Details of solid and other hazardous/non-hazardous waste generation, handling, transportation, storage, treatment and disposal will be studied. Impacts on land environment will be predicted considering activities involved in construction and operation phases. 6 Analysis of Alternatives The analysis of alternatives considered for location, layout and regasification technology will be studied and presented. 6 Analysis of Alternatives Page 6

11 7 Environmental Monitoring Programme Environmental Monitoring Programme covering the technical aspects (including methodology, parameters, frequency, location, etc., and budgetary estimates) of monitoring to check the effectiveness of mitigation measures during construction and operation phases of the proposed facility will be prepared. 8 Additional Studies 8.1 Public Consultation In line with the requirements of EIA Notification, 2006 (as amended) for Category A projects, Public Hearing will be conducted. For conducting Public Hearing, the Draft EIA Report will be prepared as per ToR and Executive Summaries in English and Local (Telugu) languages will be submitted to Andhra Pradesh Pollution Control Board (APPCB). 8.2 Social Impact Assessment The social impacts in terms of disturbance to fishing activities, impact on local infrastructure, etc. will be provided and social impacts during operation phase in terms of impact on fishing activities, employment generation and impact on nearby settlements etc. will be addressed. 8.3 Risk Analysis Risk analysis shall be carried out for proposed facility. Maximum inventory of storage at site shall be taken into account. Potential hazards shall be identified through Consequence Analysis and Fire & Explosion hazards. Hazard Identification The hazard identification consists of a qualitative review of possible accidents that may occur. Hazard identification describes the boundaries of a study in terms of materials and release conditions to be modelled, impact criteria to be used, and identifying and selecting a list of failure cases that will fully capture the hazard potential of the facilities to be studied. Consequence Analysis Consequence analysis evaluates the resulting effects if the accidents occur, and their impact on people, equipment and structures and environment or business etc. Estimation of consequences of probable events identified through hazard identification will be carried out. Risk Reduction/Mitigation Risk reduction and mitigation is necessary to bring the risks to acceptable level. Mitigation measures based on risks evaluated will be suggested. 8.4 Disaster Management Plan A Disaster Management Plan (DMP) shall be prepared in conjunction with and taking into consideration all technical reviews and suggestions as per acceptable norms. The measures to be followed during pre-cyclone, during cyclone and post cyclone will be provided as part of the DMP and a broad Spill Contingency Plan shall also be prepared for the accidental spills, if any. 7 Environmental Monitoring Programme Page 7

12 8.5 Traffic and Transportation Management Plan The existing road/rail connectivity including nearby highways to the project site will be examined and impact on the traffic due to the proposed project in terms of passenger and cargo traffic will be studied. Present and future traffic and transport facilities for the region will be analysed with measures for preventing traffic congestion. A transportation management plan will be prepared. 9 Project Benefits The project benefits in terms of improvements in the physical infrastructures and social infrastructure, employment potential and other tangible benefits will be discussed in detail in the EIA report. 10 Environmental Management Plan An Environmental Management Plan (EMP) will be formulated for the proposed project. EMP will address mitigation measures for each area i.e. air, water, soil, water environment, solid waste, green areas, etc. separately, covering all relevant aspects as per the recommendations and requirement of MoEF&CC. Based on the identified potential impacts associated with the project, an EMP will be framed for the construction and operation phases of the project, which will include: Pollution abatement and adequacy of control measures Green belt development plan (suggesting suitable species, width of plantation, spacing, etc.) Water recycle/ reuse and rainwater harvesting proposal Recommendations of measures for noise abatement Suitable mitigation measures for various potential impacts in construction and operation phases Environmental monitoring programme during construction and operation phases Budgetary estimates for implementation Institutional mechanism for implementation of EMP 11 HTL/LTL, CRZ Demarcation HTL/LTL, CRZ demarcation shall be carried out by MoEF&CC authorised agency. The proposed LNG facility layout will be superimposed on CRZ map and HTL/LTL, CRZ map in 1:4000 scale shall be submitted. 12 Structure of EIA Report Based on above tasks, the EIA report will be compiled and submitted to MoEF&CC for seeking Environmental and CRZ Clearance.
