Transcription

1 Executive Summary 1 INTRODUCTION M/s. Prosperous Energy Private Limited (PEPL), a wholly owned subsidiary of Videocon Industries Limited has proposed the 2X660MW Coal based supercritical Thermal Power Plant near Ghuman (V), Jawa (T), Rewa (Dt), Madhya Pradesh. The proposed developmental activity is Greenfield project falls under the category A of Project Activity 1(D) under the schedule as per EIA notification issued on 14th September, 2006 and hence the project requires Environmental Clearance from MoEF, Govt of India. In order to assess the likely impacts from current project on the surrounding environment and evaluating the means of alleviating the likely negative impacts, if any, from the proposed project, PEPL has retained Ramky Enviro Engineers Ltd. as their environmental consultant. The report has been prepared as per the recommendation in the Terms of References (TOR) from the Expert Appraisal Committee (EAC) at Central Level vide their letter no. J-13012/47/2011-1A.II(T) Dated NECESSITY OF THE PROPOSED PROJECT The actual growth in industrial, agricultural and domestic demand will establish that there is an appreciable shortfall in the installed capacity, demand and energy availability as on date. This shortfall will continue even after the commissioning of the proposed power plants in various parts of the State. As M.P state is the most preferred state for industrialization, the industrial demand for power will be ever increasing. Added to the industrial demand the agriculture need as well as domestic consumption coupled with the improved standard of living of the population will be on the rise. Lack of availability of sufficient electric power has always been one of the greatest deterrent to the economic growth of the state. The Potential from Hydel plants is already exploited to the maximum. Further, the hydel generation which is being restricted only to the monsoon period and peaking requirement cannot cater to the overall power requirement of the region and hence the capacity addition in thermal power sector has become necessary. Taking all these into consideration, establishment of the proposed power plant of 2X660 MW Super-Critical Coal based Thermal Power Plant near Ghuman Village, at Rewa District is justified in all aspects, since this will meet a part of the projected power demand and supply. Salient Features of the proposed Project Site are given in Table 2.1 and Technical Details of the proposed 2X660 MW Coal Based Super Critical Thermal Power Plant are given in Table 2.2 Photograph of site is given in Figure 2.1.

The predominant wind direction during the study period was blowing from SE to NW. The average temperature varies seasonally from 5.2 O C to 41 O C. Humidity is very high and rises to about 61 percent during the south-west monsoon. Ambient Air Quality The ambient air quality was monitored at 10 locations within 10Km radius of the project site as per MoEF guidelines. The study area represents mostly rural environment. Air pollutants like Suspended Particulate Matter (SPM), Particulate Matter (PM<2.5µ, PM<10µ), Sulfur dioxide (SO 2 ), Oxides of Nitrogen (NO X ), Ozone (O 3 ), and Mercury (Hg) were identified for representing the baseline status of the ambient air quality within the study area. The observed air pollutants were within the standard limits as suggested by the respective organizations. Page ES.4

5 Water Quality Status Surface water (5 no) and ground water samples (7 no) were collected from different sources within the study area and some important physical and chemical parameters including heavy metals were considered for depicting the baseline status of the study area. The samples collected from the study area were found to be fit for human consumption; however the hardness and dissolved solids in some of the ground water samples seem to be beyond desirable limit but within the permissible limits. Noise Quality Noise levels are monitored at 5 Locations in the study area. The main sources of noise in the study area are domestic activities, and vehicular traffic. The main occupation of the villagers in the study area is agricultural business. The noise levels observed in some of the rural areas are primarily owing to vehicular traffic. The day equivalents during the study period are ranging between 42.8 db (A) to 51.6 db (A) whereas, the night equivalents were in the range of 40.0 db (A) to 40.4 db (A). From the results, it can be seen that the Day equivalents and the Night equivalents were within the Ambient Noise standards of residential area standards. The day and night equivalent levels during the study period are ranging between 46.7 db (A) to 51.3 db (A). Soil Quality Soil Samples were collected from 8 locations from the study area. The ph of the soil is an important property; plants cannot grow in low and high ph value soils. The ph values in the study area are varying from 6.0 to 8.5. The organic carbon in the study area is varying from 0.03 to 0.25%. The available Nitrogen as N in the study area is varying from 107 to 175 kg/ha. The available Phosphorus is varying from 8.5 to 27 kg/ha. The available potassium in the study area is varying between 90 to 511 kg/ha. Flora & Fauna There are no endangered or endemic species of flora and fauna in core and buffer zone of the proposed project. 4 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES The proposed power plant may cause impact on the environment in two phases. During Construction phase During Operation phase a) Impacts during construction phase: The possible construction activities that contribute to the environmental impacts are: Dust Generation during leveling of earth Dust generation due to the movement of vehicles on unpaved roads Emission of pollutants from vehicular exhaust Unloading of raw materials and removal of unwanted waste material from site Accumulation of excavated earth material Page ES.5

6 The impact of the above activities would be temporary and will be confined within the project boundary b) Impacts during Operation Phase Impact on Air Quality The proposed project is a coal based thermal power plant and the major source of pollution would be the emissions from the stack. The ash content in the raw coal is considered 36% in Blended coal and 41% in Indian coal for prediction of air emissions. The important air pollutants generated from the thermal power plant are particulate matter (PM), sulfur di-oxide (SO 2 ), and oxides of nitrogen (NO X ). The major air pollutants generated from the proposed thermal power plant are given below: 1. Dust particulates in flue gas from chimney 2. SO 2 and NO X in flue gas 3. Coal dust particles due to handling of coal 4. Fly ash dust particles from ash silos and ash disposal area 5. Coal dust generated at the conveyor transfer points 6. Fly ash vented out during the unloading of fly ash from ESP hoppers to silos Table 4.1 Stack and Emission Details Proposed Plant Details Units Unit-1 Unit-2 Plant Capacity MW Type of Fuel - Coal Coal Height of the Stack m Internal Dia. of Stack M 7 7 Temperature of Flue Gas C Ambient Temperature (mean) C Velocity of Flue Gas m/s Flow Nm 3 /s Blended Indian coal Blended Indian coal Fuel Consumption TPH Ash Content (in coal used) % Sulfur Content % PM Emissions g/s SO 2 Emissions g/s NO X Emissions g/s Page ES.6

Dust collection system will be provided in coal bunkers to evacuate dust and hazardous gases like methane from the coal bunkers. To reduce the dust nuisance while loading the ash into the open trucks from fly ash silos, the fly ash would be conditioned with water spray It is proposed to cover the ash in the open trucks with tarpaulin to prevent flying of fine ash during transportation To control the particulate matter in the flue gas, an efficient electrostatic precipitator with an efficiency of 99.9% is proposed. Impact on Water Quality The water required for the proposed project shall be met from the Tonnes River through pipeline of about 35km away from the proposed site. The possible sources of wastewater within the project site are: i) Wastewater from Workshop: ii) Sewage from Domestic Use: iii) Effluent from water treatment plant iv) Blow downs from Cooling Tower v) Ash Disposal vi) Filter Backwash and Service Water The proposed mitigation measures Oily water will be treated separately to remove oil/grease before being discharged into effluent pond. Clarification is used to settle out large suspended particles and also to make the smaller colloidal particles settle Filtration will be made to a porous barrier across flowing liquid to remove suspended materials Page ES.7

8 Effluents from DM plant shall be treated in neutralization pit. The wastewater from plant units will be collected and treated in conventional effluent treatment plant. Treated effluent will be reused at maximum extent within the plant and excess treated water will be discharged to nearby natural streams according to stipulated on-land discharge standards. Impact on Noise Levels Any industrial activity, in general, consists of several sources of noise pollution. The different sources of noise pollution are mentioned below: Crusher unit Induced draft & Forced draft fans Boiler feed pumps Turbines Generators Cooling Towers Frequent vehicular movement The proposed mitigation measures are Properly designed plant and machinery (i.e. by providing inbuilt mechanisms like silencers, mufflers, and enclosures for noise generating parts) and shock absorbing pads at the foundation of vibrating equipment will be provided. In the high noise intensity working areas/zones ear muffs or ear plugs or any other suitable personal protective equipment would be provided to the workmen. Development of greenbelt around the plant boundary will diffuse the noise pollution. Provision of isolation for major noise generating equipments. Distribution of working hours among more personals working with major noise generating equipments. Regular noise level monitoring would be carried out for taking corrective action, wherever required. Vehicular movement will be restricted during peak hours and the drivers will be informed to blow horns only when required 5 ENVIRONMENTAL MONITORING PROGRAM Environmental Monitoring Program has been designed for assessing the efficiency of implementation of Environment Management Plan and to take corrective measures in case of any degradation in the surrounding environment. Different activities involved in the proposed project and their impact on various environmental attributes have been taken into account while designing a detailed environmental monitoring program. Implementation of EMP and periodic monitoring is proposed to be carried out at plant level and area level for the proposed thermal power plant and allied activities like coal handling facilities, Page ES.8

9 workshop, colony, etc. A comprehensive monitoring mechanism has been devised for monitoring of impacts due to proposed project. Plant level environmental protection measures like dust suppression, treatment and recycling of wastewater, plantation and noise control in the plant premises, housekeeping, implementation of EMP and Environmental Clearance conditions will be monitored by the plant authorities. 6 Social Impact Assessment (SIA) Study The detailed Social Assessment was carried out to examine the potential adverse and beneficial consequences of the proposed development project on the affected people. All acquired land is barren; only a little portion of land is fertile which is not being irrigated. The Research Team analyzed the needs identified during stakeholder consultations in the process of SIA and found the suitable activities to fulfill the prioritized needs of the study area, which are mentioned below where PEL have scope to initiate CSR Activities. Drinking water schemes Infrastructure especially in Aanganwadis and schools till SSC and insufficient number of education centres Awareness for Government Development schemes Local youth training for creating employment opportunities, etc. 7 PROJECT BENEFITS Agriculture is the primary way of employment for the local people within the study area. The contribution of the power plant on local social infrastructure is expected to be significant. The proposed power plant will stimulate the growth of industrial and commercial activities in and around the study area and district, by improving the availability of the power. This Project will provide a significant amount of direct and indirect employment opportunities to the local people with different skills and trades. The physical infrastructure and socio-economic status of the surrounding areas will be benefited as follows: Road transport facilities which improve accessibility Improvement in education, housing, and banking facilities Improvement in postal & communication services Recreation facilities Improvement in power supply, water supply and sanitation Improvement in economic conditions Proper training to the local people will be given to improve the employment potential within the plant Increase in revenue to the state in the form of taxes and duties from the development of local businesses Local markets with food and non-food commodities will be improved due to the increase inflow of human residents within the district Page ES.9

10 An amount of Rs. 10 Crores will be earmarked towards CSR Activities initially and later on need based allotment of funds will be done for taking up CSR activities by keeping a separate fund using minimum of 2% of profit share. 8 ENVIRONMENTAL MANAGEMENT PLAN The EMP will be integrated in all the major activities of the project, with clearly defined policies, to ensure that the ecological balance of the area is maintained and the adverse effects are minimized. It has been evaluated that the environmental impacts, due to the proposed project, are anticipated both during constructional and operational phase. Hence, the mitigative measures are planned for both the phases and the overall management plan helps to improve the surrounding environment by reducing the pollution loads from proposed activities. The EMP aims to control pollution at the source level to the possible extent with the available and affordable technology followed by the standard treatments before getting discharged. The recommended mitigation measures will synchronize the economic development of the study area with the environmental protection of the region. Environmental protection measures like monitoring & management, dust suppression, treatment and re-use of wastewater, plantation, and noise control within the project area will be looked after by the project level management. 9 CONCLUSIONS The EIA study has made an overall assessment of the potential environmental impacts likely to arise from the proposed power plant. The impact predictions indicate that the maximum GLC levels of PM, SO 2 and NO x superimposed on the baseline levels the expected impacts are minimized within a 1km from the release of pollutant from the stacks and were well within the prescribed limits of CPCB standards if blended coal is used. The wastewater from plant units will be collected in a Central Monitoring Basin and it will be treated in effluent treatment plant. Treated water quality shall be maintained as per stipulated standards. Treated effluent will be reused at maximum extent within the plant premises. Mitigation measures are proposed to minimise the adverse impacts if any due to the activity of power generation in the form of EMP. The demand for electricity has been steadily increasing in the state of Madhya Pradesh. Setting up of Power Plant in this area will benefit the society by providing better infrastructural, educational and medical facilities in the area also improvement in indirect employment and economic growth of the area.
