Expansion by addition of 1 x 660 MW Coal Based Super Critical TPP (Phase - 2) At Villages Barela and Gorakhpur, Tehsil Ghansore, District Seoni, Madhya Pradesh Final EIA/EMP Report

CHAPTER–I INTRODUCTION 1.1

PURPOSE OF THE REPORT

Economic, social and environmental change is inherent to development. Whilst development aims to bring about positive change, it can also lead to conflicts. In the past, the promotion of economic growth as the motor for increased well-being was the main development thrust with little sensitivity to adverse social or environmental impacts. The need to avoid adverse impacts and to ensure long term benefits led to the concept of sustainability. Sustainability has been accepted as an essential parameter to assess the development, if the aim of increased well-being and greater equity in fulfilling basic needs is to be met for the present and future generation. Industrialization is one of the components of today’s world development, and sustainability need to be maintained along with. Consequently, there is a need to harmonize developmental activities with the environmental concerns. Environmental Impact Assessment (EIA) is one of the tools available with the planners to achieve the above mentioned goals. An Environmental Impact Assessment (EIA) may be defined as: ”A formal process to predict the environmental consequences of human development activities and to plan appropriate measures to eliminate or reduce adverse effects and to augment positive effects”. EIA is an assessment of the possible impact—positive or negative—that a proposed project may have on the environment, together consisting of the natural, social and economic aspects. The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts when deciding whether to proceed with a project. EIA, thus, has three main functions:

To predict problems,

To find ways to avoid them, and

To enhance positive effects.

To keep the environment congenial for better standard of living, the provisions have been made in the constitution of India and many Enactments have taken place, so that, industrialization may not have adverse impact on the environment. There are many Acts / Rules / Notifications issued by MoEF in this regard, few of them are mentioned below:

Environment (Protection) Act, 1986;

Environment (Protection) Rules, 1986;

Water (Prevention & Control of Pollution) Act, 1974;

Air (Prevention & Control of Pollution) Act, 1981;

Environmental Impact Assessment (EIA) Notification, dated 14th September 2006.

As per the EIA Notification dated 14th September 2006, it is mandatory to have the Environmental Clearance for any new industry or the expansion of the industry from Ministry of Environment & Forests, Government of India, and New Delhi. The process involves an analysis of the likely impacts on the environment, recording those effects and proposed appropriate control measures and management to ensure a secure, hale and healthy environment in a report (Draft EIA/EMP Report), undertaking a public consultation exercise on the report, taking into account the comments and the report (Final EIA/EMP Report) when making the final decision and informing the public about that decision afterwards. The sole purpose of the EIA/EMP report is to provide a coherent statement of the potential impacts of a proposal and the measures that can be taken to reduce and remedy them. It contains essential information for:

the proponent to implement the proposal in an environmentally and socially responsible way;

the responsible authority to make an informed decision on the proposal, including the terms and conditions; and

the stakeholders to understand the proposal and its likely impacts on people and the environment.

1.3.2

Importance to the Country & Region Energy is one of the major inputs for economic development of any country. In the case of the developing countries like India the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments to meet them. The electricity sector in India had an installed capacity of 207.85 Gigawatt (GW) as of September 2012. India currently suffers from a major shortage of electricity generation capacity, even though it is the world's fourth largest energy consumer after United States, China and Russia. The 17th electric power survey of India report claims:

Over 2010–11, India's industrial demand accounted for 35% of electrical power requirement, domestic household use accounted for 28%, agriculture 21%, commercial 9%, public lighting and other miscellaneous applications accounted for the rest.

The electrical energy demand for 2016–17 is expected to be at least 1392 Tera Watt Hours, with a peak electric demand of 218 GW.

The electrical energy demand for 2021–22 is expected to be at least 1915 Tera Watt Hours, with a peak electric demand of 298 GW.

Hence, looking at the above power scenario the upcoming project will be beneficial for the country as well as for the region. 1.3.3

Site Selection The project activity is an expansion activity (Phase-2) proposed within the existing premises of upcoming thermal Power Plant (Phase-1) for which Environment Clearance has been granted. Initially many sites were considered for the Phase-1 project and this site at village Barela & Grakhpur was recommended by the MoEF. The expansion project has been considered in the existing premises looking at the various facilities already available or proposed in Phase-1. The project site has following advantages:

Availability of fuel i.e, coal which will be obtained from SECL/MCL and the system planned for coal transportation and railway siding for phase 1 will be used for Phase 2 with certain necessary modifications.


9



Availability of adequate water, which will be obtained from Bargi Reservoir on river Narmada located at about 13 km from the site.

Availability of adequate land for locating the plant with approach roads

Power evacuation from the site is available which can be made through 400 KV Sub Station either at Seoni or at Jabalpur

Suitability of land from topography and geological aspects

The site is more than 500 m from railway line, HFL of river & State highway and the site is not falling in sensitive zone such as Historical monuments, Wild Life Sanctuaries, National parks etc.

1.4

SCOPE OF THE STUDY The project activity was considered before the Expert Appraisal Committee (T) for its First technical presentation (ToR) on 18th Oct, 2010. The EAC has suggested Terms of References (ToR) for preparation of the Environmental Impact Assessment (EIA) Report and Environmental Management Plan (EMP) vide its File No. J13012/63/2010 - IA. II (T) & Letter dated 8th December, 2010 & 6th September, 2011. The Final EIA/EMP Report has been prepared incorporating all the prescribed ToR points by MoEF along with the issues raised and action plan for the issues raised during the public hearing.

Expansion by addition of 1 x 660 MW Coal Based Super Critical TPP (Phase - 2)At Villages Barela and Gorakhpur, Tehsil Ghansore, District Seoni, Madhya Pradesh Final EIA/EMP Report

CHAPTER–II PROCESS DESCRIPTION 2.1

TYPE AND NEED OF THE PROJECT

2.1.1

Type of the Project Jhabua Power Limited has obtained Environmental clearance for 1 x 600 MW coal based TPP (Phase 1) in villages Barela and Gorakhpur, District Seoni, Madhya Pradesh from Ministry of Environment and Forest, New Delhi in 2010 Vide F. No. J 13012/105/2008 - IA.II (T) letter dated 17th February, 2010. (A Copy of EC Letter is enclosed as Annexure-5) Now, considering the power scenario in the State of Madhya Pradesh, Jhabua Power Limited is proposing Expansion by installation of 1X660 MW Coal based Super critical TPP (Phase - 2) in villages Barela and Gorakhpur, District Seoni, Madhya Pradesh. As per EIA Notification, September, 2006 & as amended on 1st December, 2009, this project falls under Category “A” S. No. ‘1d’ (Power Generation), hence Environmental Clearance from Ministry of Environment & Forest, New Delhi is necessary.

2.1.2

Need for the Project

2.1.2.1

Power Scenario in the Country As per the “5th National Power Plan (2002-2012)” prepared by CEA, a need based installed capacity of the order of 2,12,000 MW is required by the end of 11th plan based on demand projections of 17th Electric Power Survey and a system reliability level of Loss of Load Probability less than 1% of the country. The primary resources for electric power generation are water, fossil fuel (coal, lignite, oil and natural gas) and nuclear energy. These would continue to serve as major sources of power generation in the long run, though various forms of renewable sources viz. wind, bio-mass, tides etc. will also contribute to meeting the demand. Based on the report of the Working Group of Power constituted by Planning Commission, a capacity addition of 41,110 MW is targeted in 10th plan comprising 14,393 MW of Hydro, 25,417 MW of thermal and 1,300 MW of nuclear. Out of the total thermal capacity of 25,417 MW, the coal/lignite based capacity shall be 20,053 MW.


11



For 11th Plan, CEA has identified a capacity addition requirement of 67,439 MW. The 11th Plan program is comparatively large so as to provide not only for normal growth during the 11th Plan period but also to compensate for any shortfall in the capacity addition during the 10th plan period. 2.1.2.2

Power Development Scenario Beyond 11th Plan (2012-20) The Indian power system requirement has been assessed to need a hydro power and thermal/nuclear power mix in the ration of 40:60 for flexibility in system operation depending on typical load pattern. The motion to achieve this mix and to accelerate the hydro electric power generation of 50, 000 MW has been already initiated by Government of India (GoI). CEA has identified new hydro schemes aggregating to a capacity of 30,000 MW for yielding benefits during the 12th Plan period (2012-2017). These schemes have been identified based on their present status as available with the CEA. Nuclear Power Corporation has planned to add nuclear power projects aggregating to 12,000 MW to be commissioned in year 2012-2017. With the capacity additional of 21,180 achieved during 10th Plan and 78,578 MW assessed as required during the 11th plan, it is expected that “Power to All” would be achieved by 2012. A tentative capacity addition of 82,200 MW has been envisaged for the 12th plan. This comprises of 30,000 MW hydro, 40,200 MW thermal and 11000-13000 MW of Nuclear Power Plant.

STEAM TURBINE The steam turbine will be of 3000 rpm, tandem compound, single reheat, regenerative, condensing, three (3) cylinder machine with eight (8) uncontrolled extractions for regenerative feed water heating. The main steam parameters at 100% TMCR load will be 242.23 bars at 565°C before emergency stop valves of HP turbine and reheat steam parameters of 49.34 bars and 593°C at inlet to IP turbine and the condenser pressure will be of 0.1 bars. At turbine valve wide open (VWO) condition the turbo-generator set will be able to operate continuously with a throttle steam flow of about 105% TMCR condition. The steam turbine generator will be suitable for tropical climate prevailing in India and indoor installations on reinforced concrete top deck preferably supported on vibration isolation system consisting of steel helical springs and visco dampers. CONDENSING EQUIPMENT Single pass surface condenser capable of maintaining the required vacuum while condensing steam at the maximum rating of the turbine will be provided. Other recoverable steam and condensate will also be routed to the condenser shells. The steam will be condensed in the condenser by circulating water passing through the condenser tubes. The condenser arrangement will be such that on-load maintenance of one half of the condenser at a time is possible by isolating the same from cooling water inlet and outlet sides. The condenser will be of divided water box design with rolled steel construction of body and water chamber. Tubes in the condensing zone and in the air cooling zone will be of Stainless Steel to SA 249 TP 304. Tube sheet will be of Carbon steel to SA 516 Gr. 70 or equivalent. The condensers will have integrated air cooling zone and it should be designed so as to accept 60% quantity of steam during turbine HP and LP bypass operation without any undue vibration, thermal stress etc. The condenser axis will be at right angle to the turbo-generator axis. CONDENSER AIR EVACUATION SYSTEM Air evacuation systems commonly used for condensers are Steam ejectors or mechanical vacuum pumps. With increase in unit rating and steam conditions, it is uneconomical to provide large quantities of relatively low conditions steam to steam jet ejector. The capacity of vacuum pump rises steeply with increase in condenser back pressure than the ejector and hence when the air leakage in condenser


20



increases more than its design value, the vacuum pump can handle more air than ejectors of the same capacity. Based on the operating conditions, operation flexibility, layout convenience, system reliability and economics, the vacuum pumps are selected for condenser Air evacuation system.

DEAERATING HEATER AND CLOSED HEATERS The proposed unit will be provided with a variable pressure type deaerator with a feed water tank of adequate capacity. Vent condenser will be provided with the deaerator to minimize wastage of steam. The deaerator will be spray or spray-cumtray type and will be designed to deaerate all the incoming condensate and drain flows to keep the oxygen content of the condensate below the permissible limit. CONDENSATE EXTRACTION PUMPS The proposed unit will have three (3) x 50% capacity (2W + 1S) condensate extraction pumps, which will take suction from condenser hot well and discharge through common supply line to the Deaerator. The condensate extraction pumps will be vertical motor driven centrifugal can-type, multistage, with double suction first stage impellers. The pumps will be located indoors near the condenser with the pump base plates at ground floor and will be arranged for below ground suction from the condenser hot well.

TECHNOLOGY & PROCESS DESCRIPTION In thermal power generation, chemical energy of coal is first converted into thermal energy (during combustion), which is then converted into mechanical energy (through a turbine) and finally into electrical energy (through a generator). Figure 2.6 shows the process flow sheet for coal fired thermal power plant. Its raw materials are coal, air and water. The coal travels from the coal handling plant by conveyor belt to the coal bunkers, from where it is fed to the pulverising mills which grind it as fine as face powder. The finely powdered coal mixed with air is then blown into the boiler by a fan where it burns like a gas. The boiler walls are lined with boiler tubes containing high quality demineralised water (known as boiler feed water). The combustion heat released from the coal is absorbed by the boiler tubes and the heat converts the boiler feed water into steam at high pressure and temperature. The steam discharged through nozzles on the turbine blades, makes the turbine rotate. Generator is coupled to the end of the turbine. When the turbine rotates, the electricity is produced in generator, which is passed to the stepup transformer which increases its voltage so that it can be transmitted efficiently over the power line of the grid. The power is evacuated via Switch Yard through a Transmission System.

2.4.1

Steam Generator and Accessories Steam Generator The steam generator will be once through type, water tube, direct pulverised coal fired, balanced Final furnace, single reheat, radiant, wet bottom type, suitable for outdoor installation, top supported and designed for firing 100% Indian coal rated to deliver about 2100 TPH of superheated steam at 250 bar(a), 568°C (±5°) when supplied with feed water at a temperature of 290°C at the economiser inlet under BMCR condition. The combustion system will be of pulverised coal firing with Low NOX type coal burners. The firing system will be either corner firing (tangential) or front and opposite wall firing as per the standard design feature of steam generator manufacturer. The steam generator will be designed for continuous satisfactory operation for the specified range of coal without any need for auxiliary fuel for flame stabilisation above minimum load operation. The furnace will be conservatively designed for fuel to burn completely and to avoid any slagging in the furnace and excessive fouling in the super heater sections of the boiler. The design flue gas velocities will be carefully selected to minimise erosion of pressure parts and other vital components on account of ash. The steam generator will be designed in accordance with the latest provisions of Indian Boiler Regulations. The steam generator will be designed to give the maximum efficiency when firing the coal. Capacity of steam generating unit will be so selected as to ensure adequate margin over the requirement of Turbine at valve wide open (VWO), auxiliary steam requirement for soot blowing operation, start-up of the adjacent unit, and derating of the steam generating unit due to prolonged use. The steam generator will be designed to operate with “the HP Heaters out of service” condition (resulting in lower feed water temperature at Economiser inlet) and deliver steam to meet the turbo-generator requirement at base load. Economiser section of the boiler will be non-steaming type. Super heater section will be divided in convection and radiant zones and designed so as to maintain rated steam temperature of 568°C (±5°) at outlet. Main steam attemperation stations with provision for spraying water tapped off from feed water piping will be provided for steam temperature control. Air preheaters of rotary tri sector type will be provided with a set of soot blowers of automatic sequential electrically operated type, arranged for on-load cleaning of the heat transfer surfaces. Inline with the plant operating capability requirements, the


32




steam generator will be designed for both constant as well as sliding pressure operation. Thermal design of steam generator and the selection of materials will be suitable for both the operational modes. Final system of the boiler will be provided with two (2) Forced Final Fans, two(2) Primary Air Fans and two (2) Induced Final Fans with suitable capacity and control arrangement, each independently capable of meeting the requirement at 60% BMCR load. The forced Final fans will control total airflow to boiler and the induced Final fans will control furnace Final of the boiler through automatic control loops. The crushed coal will be received from the coal handling plant through conveyors and stored in the coal bunkers of about 16 hours storage capacity and the same will be fed to the coal pulverisers utilising gravimetric feeders. The pulverised coal will then be distributed to the Low NOx coal burners from each mill for combustion in the furnace of the boiler through coal conveying pipes. It is considered that even with one pulverising coal mill out of service, it will be possible to achieve 100 % BMCR. The steam generating unit will be provided with arrangement for start-up and at low load stabilisation periods when firing coal utilising liquid fuel such as LDO/HFO. The complete boiler will be top supported type and will be provided with all supporting steel structures, platforms, galleries, elevator and stairways for easy approach and maintenance of the unit. Adequate weather protection will be provided for instruments and operating personnel. Necessary lining and insulation along with fixing materials to limit outside surface temperature to a safe level will be provided. Monorails and hoists required for handling heavy equipment, motors, fans etc. will be supplied along with the steam-generating unit for ease of maintenance. The steam generator and its auxiliaries will be capable of continuous operation at their maximum continuous rating within range of power supply frequency variation from 47.5 Hz to 51.5 Hz. Provision for future installation of FGD system i)

At turbine valve wide open (VWO) condition the turbo-generator set will be able to operate continuously with a throttle steam flow of about 105% TMCR condition. HP and LP turbine bypass station will be provided as a part of turbine package. The bypass station will act not only as a protection to the unit during pressure rise resulting from sudden load throw off but also enable operation of the unit at loads lower than the controllable range of load. This will also permit quick/hot starts of the unit in case of STG tripping. The bypass station will be sized for a flow corresponding to about 60% of BMCR. A fully automatic gland sealing system will be provided for the turbine, which will have provision for receiving steam from auxiliary steam header during start-up and low load operation. The turbo-generator will be equipped with electro-hydraulic governing system ensuring stable operation under any grid fluctuation and load throw off condition. The turbo-generator will be equipped with an electric motor driven turning gear and manual hand barring gear for emergency purpose. The unit will also be provided with self-contained lubricating oil system for supplying oil to turbine and generator bearings and also to hydrogen seal oil system of the generator.

2.4.4

Coal Handling Plant The entire coal handling plant is designed for catering to 1x600 and 1x660 MW units of which one unit is being installed now and the second unit shall be installed later. Provisions are to be made in the first phase of this coal handling plant for addition of


35




the necessary equipment at a later date to suit this requirement. Coal Handling Plant (CHP) design shall be based on coal GCV of 3150 kCal/kg and maximum daily coal consumption of 22008 Tons (unit-1: 10320T & Unit-2: 11688T). Rated capacity of CHP shall be 1800 T/hr. CHP shall be sized considering input coal size of below 250mm. Two (2) streams, ‘A’ stream and ‘B’ stream are provided. Both the streams of conveyor will be in operation without any standby. Description of CHS for phase 2 Coal from the wagons will be unloaded into wagon tippler hopper by wagon tipplers. Two wagon tipplers are provided in Phase-1 of the project. One additional wagon tippler is envisaged in Phase-2. The wagon tipplers are common to both the units . Apron feeder under the wagon tippler hopper would extract coal from the hopper and distribute it equally onto downstream conveyors which will also be receiving the feed from respective tippler hoppers of phase-1. This in turn will convey the coal to a crusher house, where the incoming coal would be screened and the oversize crushed. Crushed coal would be conveyed to the bunkers, if necessary or stockpiled in the coal stockyard by means of stacker cum reclaimer. Suitable stacking and reclaiming systems is envisaged. The entire conveying system from receipt of coal to conveying up to the bunker will have 100% standby arrangement for reliability. Necessary diversions/ interchanges by means of diverter gates / Belt feeders will be provided at strategic locations of the conveying system so as to ensure adequate flexibility in operation. The storage yard for the power plant is sized considering an average pile height of 10 m. Stockpile capacity is considered as 2,33,760 Tonnes. This storage capacity caters for about Twenty (20) days’ of plant operation for phase - 2 unit with Indian coal having an average calorific value of 3,150 kCal/kg. Coal Receipt, Unloading and Crushing Coal from the mines to plant will be transported by railway wagons (BOX-N type wagons). Considering each wagon carrying 55 tonnes of coal, no. of wagons required per day will be 400 to cater to the daily requirement of 22008 tonnes for the two units. One additional tippler will be envisaged inside the tippler house in Phase-2 to cater to both the units. In phase-2, all the three tipplers will be in operation if wagons of capacity 55T are received at site. The first two tipplers will be operating at 1200TPH each & the third tippler will be operated such that material conveyed by the tunnel conveyor envisaged in phase-2 is equally distributed onto the


36

Study of Land use/Land Cover around Proposed Project Activity Using Satellite Remote Sensing Data The study was taken up to prepare current land use / land cover within 10 Km radius around the proposed project boundary at Villages Barela and Gorakhpur, Tehsil Ghansore, District Seoni, Madhya Pradesh. (A)

DATA USED Indian Remote Sensing satellite IRS LISS III MX digital FCC (False Color Composite) of current vintage data at 23.5 m spatial resolution has been used for preparation of Land use/ Land cover thematic map of present study area. Survey of India toposheet as a reference map on 1:50,000 scale has been used for preparation of base layer map like road, rail network, contour, drainage, village and rectification of satellite data.

Data Analysis System (ERDAS) Imagine 9.2 (B) METHODOLOGY The methodology used for the study area consists of following components. (i)

GEOREFERENCING OF SATELLITE IMAGE

Satellite image has been georeferenced by using registered SOI toposheet as a reference map taking suitable Ground Control Points (GCP) points like intersection point of railway, Road network, landmarks and permanent feature. Finally Images were re-projected in UTM projection and their respective zone.


48



(ii) BASE MAP LAYER CREATION Base map has been prepared using Survey of India Toposheet as a reference map on 1:50000 scale. In base layer linear and point feature like road, rail, canal, village location and plant site have been created in vector data format. Base map layer information has been used for analysis of surrounding feature like road, rail, village location near Plant site activity through superimposed on thematic map for data integration. (iii) INTERPRETATION OF SATELLITE IMAGE Hybrid technique has been used i.e. visual interpretation and digital image processing for identification of different land use and vegetation cover classes based on spectral signature of geographic feature. Spectral signature represents various land use class. Image interpretation keys are developed based on image characteristics like color, tone, size, shape, texture, pattern, shadow, association etc, which enables interpretation of satellite images for ground feature. (iv) GROUND TRUTH DATA COLLECTION Ground data on geo-environmental components of the study area were collected for verification of information of the different features of the study areas, which are responsible for the occurrence of specific spectral reflectance behavioural patterns. The ground truth detailed information on agricultural practices; wastelands, mining, industrial area etc. were collected along with other land features. Ground truth has been carried out for verification of the ground features (esp. one in doubt) interpretation accuracy and reliability of remotely sensed data, which cannot be interpreted directly on satellite imagery. (C)

RESULTS In the present study, both digital image processing and visual interpretation technique were applied to generate output of Land use / Land cover map of study area on 1: 50,000 scale. A standard False Colour Composite (FCC) image has also been generated on the same scale. The study area has been divided into the above major classes of land use for the purpose of computing the area.

SEISMICITY OF AREA Many parts of the Indian subcontinent have historically high Seismicity. Seven catastrophic earthquakes of magnitude greater than 8 (Richter scale) have occurred in the western, northern and eastern parts of India and adjacent countries in the past 100 years. By contrast, peninsular India is relatively seismic, having suffered only infrequent earthquakes of moderate. The main seismogenic belts are associated with the collision plate boundary between the Indian and Eurasian plates. The hazard map shows contours joining locations of equal expected peak accelerations in rock expressed in percentage. The study area lies in the Seismic Zone II under area of moderate seismic risk by national standards.
