2.0 PROJECT DESCRIPTION

This chapter deals with the technical details of the proposed power plant, details of

infrastructure, various sources of pollution and the measures proposed to control

pollution.

2.1 Type of the Project

SKS Power Generation (Chhasttisgarh) Limited proposes to set-up a coal based

thermal power project of 4X300 MW capacity at Binjkot, Darramura, Badejampali,

Gindola villages in Kharsia tehsil of Raigarh district, Chhattisgarh state. Boilers of

the project shall be pulverized coal fired type and based on sub-critical

technology. It is envisaged that coal for the power plant from captive coal mine

Fathepur coal block would be linked to SECL coal mines.

2.2 Need for the Project

Electric energy is known to be the vital utility and prerequisite for stimulating the

industrial and commercial activities in economic development of the nation. In

post-independent era, the country has witnessed significant growth in power

sector especially in power generation. However, the demand has escalated so

high that in spite of the phenomenal increase in installed capacity of power

generation, there has been sustained deficit in power supply and is expected to

increase further in future. Thermal power has always remained major component

among different types of power generation in India.

In order to cope up with the ever increasing gap in power demand and supply,

Government of India has widened the scope of private sector participation in

electricity generation by passing a resolution in October 1991 and allowing them

to set-up power plants. Moreover, the measures initiated through the Electricity

Act 2003 have further enhanced the opportunities to private participation in

power sector, especially in thermal power generation.

With a view to harvest the current opportunity, SKS Power Generation

(Chhattisgarh) Limited initiated proceedings for setting up of thermal power plant

in the country.

Considering the existing and escalating demand of electricity in the northern grid,

SKS Power Generation (Chhasttisgarh) Limited proposes to develop a power

project of 1200 MW (4x300MW) capacity at Binjkot, Darramura, Badejampali,

Gindola villages in Kharsia tehsil of Raigarh district, Chhattisgarh state.

2.3 Project Location and Layout

Inline with the MoU signed with Govt. of Chhattisgarh state and on the basis of

the prerequisites for selecting a site for the proposed 4X300 MW power project,

the site selection was carried out through alternative site evaluation within

Raigarh district. Four (4) alternate sites were identified in Chhattisgarh state and

after evaluation, a site at Binjkot, Darramura, Badejampali, Gindola villages in

2.7 Sources of Pollution

The various types of pollution from the proposed power plant are categorized

under the following types:

• Air pollution;

• Water pollution;

• Solid waste; and

• Noise pollution.

The major type of pollution from the power plant is gaseous emissions. In

addition, wastewater and solid waste will also be generated. The quantities and

the composition of the gaseous, liquid and solid waste that are likely to be

generated in the plant will be managed and treated such that their final disposal

into the environment meets all the statutory requirements and thus the

environmental impacts are minimized.

2.7.1 Air Emissions

The major pollutants emitted from the power plant stack will be SO2, NOx and

particulate matter. Proper control measures as described below will be installed to

minimize the stack emissions within the stipulated/permissible limits prescribed

by National Ambient Air Quality Standards.

• Suspended Particulate Matter

Suspended Particulate Matter (SPM) is one of the important pollutants from the

proposed power plant. High efficiency (>99.9%) electrostatic precipitators are

proposed to be installed to limit the particulate matter emissions to below 50

mg/Nm3.

• Sulphur dioxide

The sulphur content in coal is about 0.4%. Two stacks multi flue of 275-m height

will be provided, as per CPCB/MoEF Norms, to disperse the gaseous emissions.

• Oxides of Nitrogen

To reduce the NOx emissions from the steam generator, all provisions in the

steam generator design and fuel firing system will be made. Necessary

confirmation from the boiler manufacturers regarding concentration from stack

will be less than 350 mg/Nm3 generation of NOx would be taken as a measure to

control production of this pollutant right at the source. The details of stacks and

emission rates are presented in Table-2.6. The emission rate calculations are

given in Annexure-IV.

• Thermal Pollution

Heat loss through the stack represents only about 8% to 10% of the total heat

input to the furnace. The quantum of heat so lost to the atmosphere is not

significant. It may further be noted that the area is subjected to moderate wind

speed and good rainfall.

The effect of tall chimneys, which are being installed primarily to take care of the

gaseous discharges, would also indirectly help in diffusing the thermal pollution.

Due to the high kinetic energy gained by the flue gases issuing from the stack,

the effective rise of the plume would ensure discharge of flue gas at a

considerably higher stratum ensuring dilution of the gas dispersed leaving the

local environment virtually unaffected.

be made to utilize 100% fly ash as per the Fly Ash Notification, 1999 and as

amended later.

The ash which is not lifted by the potential user will be disposed off in the ash

dyke using dry system of fly ash collection. The fleet of bulkers/trucks will dump

the ash in the ash dyke. Water sprinklers will be provided at the ash dyke to

sprinkle water for suppression of dust generated. We are also envisaging for fly

ash fine grinding system to fine grind it and send to oversees market- ready mix

to cement.

3.3 Meteorology

The meteorological data recorded during the study period is very useful for proper interpretation of the baseline information regarding proposed plant area and surrounding area for air quality dispersion. Historical data on meteorological parameters will also play an important role in identifying the general meteorological regime of the region.

The year may broadly be divided into four seasons:

• Winter season : December to February • Pre-Monsoon season : March to May • Monsoon season : June to September • Post-Monsoon season : October to November

3.3.1 Methodology

The methodology adopted for monitoring surface observations is as per the standard norms laid down by Bureau of Indian Standards (IS : 8829) and India Meteorological Department (IMD). On-site monitoring was undertaken for various meteorological variables in order to generate the site-specific data. Data was collected every hour continuously from 1st March to 31st May 2008 representing pre-monsoon season.

3.3.1.1Methodology of Data Generation

The Central Monitoring Station (CMS) equipped with continuous monitoring equipment was installed on top of a residential building at a height of 3.0 m above ground level to record wind speed, direction, relative humidity and temperature. The meteorological monitoring station was located in such a way that it is free from any obstructions and as per the guidelines specified under IS: 8829. Cloud cover was recorded by visual observation. Rainfall was monitored by rain gauge.

The continuous recording meteorological instrument of Dynalab, Pune (Model No.WDL1002) has been used for recording the met data. The sensitivity of the equipment is given in Table-3.3.1.

3.3.2.3 Comments

The India Meteorological Department (IMD) records the data at two times a day viz. 0830 hr and 1730 hr while the site specific data has been recorded at an hourly interval. On comparison of site specific data generated for study period vis-à-vis the IMD data, slight variations were found. The following observations are brought out:

• The temperature recorded on site when compared vis-à-vis the IMD data, slight

variations were found. The maximum and minimum temperatures recorded at site during study period were 42.0oC and 21.3 oC, whereas the maximum and minimum temperature recorded at IMD, Raigarh for the same season are 42.6oC and 20.3oC respectively;

• The relative humidity was observed to range from 20.3% to 41.3% during the study period whereas according to IMD Raigarh data the relative humidity was observed to range from 20.4% to 41%. The variation could be because of the fact that the RH values considered for the site are actual values while the range of IMD, Raigarh data represents the average values for 30 year period.

The data generated at continuous monitoring station at project site when compared with the data recorded at IMD, it can be observed that the data generated at the site is broadly compatible with regional meteorology, except minor variations as descried above.

3.4 Air Quality

The ambient air quality with respect to the study zone of 10-km radius around the proposed plant site forms the baseline information. The various sources of air pollution in the region are industrial, traffic, urban and rural activities. This will also be useful for assessing the conformity to standards of the ambient air quality during the plant operation. The study area represents mostly rural environment.

This section describes the selection of sampling locations, methodology adopted for sampling, analytical techniques and frequency of sampling. The results of monitoring carried out during study period are presented in Annexure-V.

3.4.1 Methodology Adopted for Air Quality Survey 3.4.1.1 Selection of Sampling Locations

The baseline status of the ambient air quality has been assessed through a scientifically designed ambient air quality monitoring network. The design of monitoring network in the air quality surveillance programme has been based on the following considerations:

• Meteorological conditions on synoptic basis; • Topography of the study area; • Representatives of regional background air quality for obtaining baseline status;

and • Representatives of likely impact areas.

Ambient Air Quality Monitoring (AAQM) stations were set-up at Twelve locations with due consideration to the above mentioned points. Table-3.4.1 gives the details of environmental setting around each monitoring station. The location of the selected stations with reference to the plant boundary is given in the same table and shown in Figure-3.4.1.

3.4.1.2 Frequency and Parameters for Sampling

Ambient air quality monitoring was carried out at a frequency of two days per week at each location representing pre-monsoon season. The baseline data of air environment was generated for the following parameters:

• Total Suspended Particulate Matter (TSPM); • Respirable Particulate Matter (RPM); • Sulphur dioxide (SO2); • Oxides of Nitrogen (NOx); • Carbon Monoxide (CO);and • Ozone (O3)

3.5 Water Quality

Selected water quality parameters of surface and ground water resources within 10 km radius of the study area has been studied for assessing the water environment and evaluate anticipated impact of the project. Understanding the water quality is essential in preparation of Environmental Impact Assessment and to identify critical issues with a view to suggest appropriate mitigation measures for implementation.

The purpose of this study is to:

• Assess the water quality characteristics for critical parameters; • Evaluate the impacts on agricultural productivity, habitat conditions,

recreational resources and aesthetics in the vicinity; and • Predict impact on water quality by this project and related activities.

The information required has been collected through primary surveys and secondary sources.

3.5.1 Methodology

Reconnaissance survey was undertaken and monitoring locations were finalized based on:

• Drainage pattern; • Location of residential areas representing different activities/likely impact areas;

and • Likely areas, which can represent baseline conditions. Three surface water and eight ground water sources covering 10-km radial distance were examined for physico-chemical, heavy metals and bacteriological parameters in order to assess the effect of industrial and other activities on surface and ground water. The samples were analyzed as per the procedures specified in 'Standard Methods for the Examination of Water and Wastewater' published by American Public Health Association (APHA). Samples for chemical analysis were collected in polyethylene carboys. Samples collected for metal content were acidified with 1 ml HNO3. Samples for bacteriological analysis were collected in sterilized glass bottles. Selected physico-chemical and bacteriological parameters have been analyzed for projecting the existing water quality status in the study area. Parameters like temperature, Dissolved Oxygen (DO) and pH were analyzed at the time of sample collection.

The methodology for sample collection and preservation techniques was followed as per the Standard Operating Procedures (SOP) mentioned in Annexure-VI.

3.6 Soil Characteristics

It is essential to determine the potential of soil in the area and identify the current impacts of urbanization and industrialization on soil quality and also predict impacts, which may arise due to the plant operations. Accordingly, a study of assessment of the baseline soil quality has been carried out.

3.6.1 Data Generation

For studying soil profile of the region, sampling locations were selected to assess the existing soil conditions in and around the project area representing various land use conditions. The physical, chemical and heavy metal concentrations were determined. The samples were collected by ramming a core-cutter into the soil up to a depth of 90 cm. The present study of the soil profile establishes the baseline characteristics and this will help in future in identifying the incremental concentrations if any, due to the operation of the plant. The sampling locations have been identified with the following objectives:

• To determine the baseline soil characteristics of the study area; • To determine the impact of industrialization on soil characteristics; and • To determine the impact on soils more importantly from agricultural

productivity point of view.

Eight locations within 10-km radius of the proposed plant boundary were selected for soil sampling. At each location, soil samples were collected from three different depths viz. 30 cm, 60 cm and 90 cm below the surface and are homogenized. This is in line with IS: 2720 and Methods of Soil Analysis, Part-1, 2nd edition, 1986 of (American Society for Agronomy and Soil Science Society of America). The homogenized samples were analyzed for physical and chemical characteristics. The soil samples were collected during pre-monsoon season. The samples have been analyzed as per the established scientific methods for physico-chemical parameters. The heavy metals have been analyzed by using Atomic Absorption Spectrophotometer and Inductive Coupled Plasma Analyzer.

The methodology adopted for each parameter is described in Table-3.6.1.

The environmental assessment of noise from the industrial activity, construction activity and vehicular traffic can be undertaken by taking into consideration various factors like potential damage to hearing, physiological responses, and annoyance and general community responses.

The impact of noise sources on surrounding community depends on:

• Characteristics of noise sources (instantaneous, intermittent or continuous in

nature). It can be observed that steady noise is not as annoying as one which is continuously varying in loudness;

• The time of day at which noise occurs, for example high noise levels at night in

residential areas are not acceptable because of sleep disturbance; and

• The location of the noise source, with respect to noise sensitive land use, which determines the loudness and period of exposure.

The environmental impact of noise can have several effects varying from Noise Induced Hearing Loss (NIHL) to annoyance depending on loudness of noise. The environmental impact assessment of noise from the plant operations and vehicular traffic can be undertaken by taking into consideration various factors like potential damage to hearing, physiological responses, and annoyance and general community responses.

The main objective of noise monitoring in the study area is to establish the baseline noise levels, and assess the impact of the total noise expected to be generated by the construction and operation of the proposed plant facilities around it.

3.7.1 Identification of Sampling Locations

A preliminary reconnaissance survey has been undertaken to identify the major noise generating sources in the area. Noise at different noise generating sources has been identified based on the activities in the village area and ambient noise due to traffic. The noise monitoring has been conducted for determination of ambient noise levels in the study area. The noise levels at each location were recorded for 24 hours. The environment setting of noise monitoring locations is given in Table-3.7.1 and shown in Figure-3.7.1.

3.7.2 Method of Monitoring

Sound Pressure Level (SPL) measurements were measured at all locations. The readings were taken for every hour for 24 hours. The day noise levels have been monitored during 6 am to 10 pm and night levels during 10 pm to 6 am at all the locations covered in 10-km radius of the study area.

3.7.3 Methodology of Data Generation 3.7.3.1 Instrument Used for Monitoring

Noise levels were measured using integrated sound level meter manufactured by Quest Technologies, USA (Model No.2900). The integrating sound level meter is an integrating/ logging type with Octave filter attachment (model OB-100) with frequency range of 31.5 to 16000 Hz. This instrument is capable of measuring the Sound Pressure Level (SPL), Leq and octave band frequency analysis.

3.7.3.2 Method of Monitoring

Noise level monitoring was carried out continuously for 24-hours with one hour interval starting at 6.00 hrs to 6.00 hrs next day. The noise levels were monitored on working days only and Saturdays, Sundays and public holidays were not monitored. During each hour, Leq were directly computed by the instrument based on the sound pressure levels. Lday (Ld), Lnight (Ln) and Ldn values were computed using corresponding hourly Leq of day and night respectively. Monitoring was carried out at ‘A’ response and fast mode.

3.7.3.3 Parameters Measured During Monitoring

For noise levels measured over a given period of time, it is possible to describe important features of noise using statistical quantities. This is calculated using the percent of the time certain noise levels are exceeding the time interval. The notation for the statistical quantities of noise levels are described below: • L10 is the noise level exceeded 10 per cent of the time; • L50 is the noise level exceeded 50 per cent of the time; and • L90 is the noise level exceeded 90 per cent of the time.

Equivalent Sound Pressure Level (Leq):

The Leq is the equivalent continuous sound level, which is equivalent to the same sound energy as the actual fluctuating sound measured in the same period. This is necessary because sound from noise source often fluctuates widely during a given period of time. This is calculated from the following equation:

60

)_LL(LL

29010

50eq +=

Lday is defined as the equivalent noise level measured over a period of time during day (6 am to 10 pm). Lnight is defined as the equivalent noise level measured over a period of time during night (10 pm to 6 am). A noise rating developed by E P A for specification of community noise from all the sources is the Day-Night Sound Level, (Ldn).

Day-Night Sound Level (Ldn):

The noise rating developed for community noise from all sources is the Day-Night Sound Level (Ldn). It is similar to a 24-hr equivalent sound level except that during night time period (10 pm to 6 am) a 10 dB (A) weighting penalty is added to the instantaneous sound level before computing the 24-hr average. This night time penalty is added to account for the fact that the noise during night, when people are usually in sleep, is judged as more annoying than the same noise during the day time. The Ldn for a given location in a community may be calculated from the hourly Leq’s, by the following equation.

)]}10(8+)10(16[24/1log{10=L 10/)10+L(10/Ldn

nd

Where Ld is the equivalent sound level during the day time (6 am to 10 pm) and Ln is the equivalent sound level during the night time (10 pm to 6 am).

3.7.4 Presentation of Results

The statistical analysis is done for measured noise levels at ten locations. The parameters are analyzed for L10, L50, L90, Leq, Lday, Lnight, and Ldn. The statistical analysis results are given in Table- 3.7.2.

3.7.5 Observations

Day time Noise Levels (Lday)

The day time noise levels at all the locations were ranged in between 42.3 to dB(A) to 54.7. The maximum value (54.7 dB (A)) was recorded at Nawapara village (N7), and the minimum value (42.3 dB (A)) was recorded at Plant site (N1). Night time Noise Levels (Lnight)

The night time noise levels were ranged in between 38.5 dB (A) to 49.0 dB (A). The maximum value (49.0 dB (A)) was recorded at Gindola village (N5) and the minimum value (38.5 dB (A)) was recorded at Plant site (N1).

3.8 Flora and Fauna Studies 3.8.1 Introduction

An ecological survey of the study area was conducted particularly with reference to the listing of species and assessment of the existing baseline ecological (Terrestrial and Aquatic ecosystem) conditions in the study area.

3.8.2 Objectives of Ecological Studies

The present study was undertaken with the following objectives: • To assess the nature and distribution of vegetation in and around the project

site; • To assess the distribution of animal life spectra; and • To ascertain migratory routes of fauna and possibility of breeding grounds.

3.8.3 Methodology Adopted for the Survey

To achieve the above objectives, a detailed study of the area was undertaken in 10-km radius area with the proposed project site as its center. The different methods adopted were as follows:

• Compilation of secondary data with respect to the study area from published

literature and Government agencies; • Generation of primary data by undertaking systematic ecological studies in the

area; • Discussion with local people so as to elicit information about local plants,

animals and their uses; and • Gathering data for ethno biology. The present report gives the review of published secondary data and the results of field sampling conducted during summer season-2008.

3.8.4 Review of Secondary Published Data

From Records of Botanical Survey of India � Floral structure

The Chhattisgarh Plains has long been cultivation and at present only small patches of degraded tropical dry deciduous forests have been left, if at all. It is rather more characterized by scattered stunted and crooked trees and shrubs of Butea monosperma, Lagerstroemia parviflora, Albizia spp., Acacia leucophloea, A.nilotica spp. Indica. Mangifera indica. Terminalia spp., Ficus racemosa. F.benghalensis. F.religiosa, Azadirachta indica, Pithecellobium dulce, Syzygium cumini, Mitragyna parvifolia, Aegle marmelos, diospyros melanoxylon, Bauhinia spp., Calotropis spp., Caesalpinia bonduc, Ipomoea carnea and Mimosa himalayana, with several climbers like ziziphus oenoplia, Celastrus patina, Ipomoea spp., Atylosia scarabaeoides and Cissampelos pareira. Particular mention may be made of the Mahua trees, Madhuca longifolia var. latifolia, which are

considered sacred and stay unlopped. In addition, Albizia spp., Dalbergia sissoo, Delonix regia, Cassia fistula, Peltophorum pterocarpum, Pongamia pinnata, Eucalyptus hybrids, and Pterocarpus marsupium are frequently planted on the roadsides. The ground flora, during rainy and post rainy season, consists of several annual or perennial species of grasses, sedges and other herbs and creepers, but by the middle of winter it is completely grazed and presents a bare desolate spectre. Mention may be made of two epiphytic orchids, Vanda tessellate and V.testacea which grow freely on Mangifera Indica, Butea monosperma, Madhuca longifolia var latifolia, Diospyros melanoxylon and Terminalia spp. The former with large brown banded flowers immediately catches the eye.

� Tropical Moist Deciduous Forests

A good development of these forests with a fair amount of sal can be observed in the reserved forests around Chilpi, Rangakhar, Borai, sitanadi, Khallari and Taurenga. It has tall trees of Shorea, robusta, Terminalia spp. Pterocarpus marsupium, Dalbergia panigulata, Adina ccordifolia, Stereospermum chelonoides, Schleichera oleosa, Garuga pinnata, Lannea coromandelica, Bombax ceiba, Soymida febrifuga and Boswellia serrata, and smaller trees like Lagerstroemia parviflora, Briedelia squamosa, Mallotus philippensis, Diospyros melonoxylon, Anogeissus latifolia, Buchanania lanzan, Gmelina arborea, Antidesma ghaesembilla, Ficus spp., Grewia tiliifolia and Cassia fistula and shursb like Breynia vitisidaea, Embelia tsjeriam – cottam, Chloroxylon swietenia, Holarrhena antidysenterica, Casearia graveolens, helicteris isora, Semecarpus anacardium, Ochna obtusata, Indigofera cassioides, Woodfordia fruticosa and species of Leela and Desmodium. The common in Chhatisgarh bamboo, Dendrocalamum strictus, forms dense thickets. The conspicuous climbers and ramblers in these forests are Millettia extensa, Smilax zeylanica, Bauhinia vahlii, Olax scandens, combretum roxburghii, Ventilago denticulate, Ichnocarpus frutescens, Dioscorea pentaphylla, D.puber, D.oppositifolia and D.bulbifera.

The undergrowth in dense forests is often sparse, and not much varied. The common species are Eranthemum purpurascens, Perilepta edgeworthiana, Nelsonia canescens, Phoenix acaulis, Chlorophytum tuberosum, globba racemosa, G.bulbifera, Curcuma spp., Zingiber spp., Tacca leontopetaloides, Carex speciosa, and a few ground orchids like eulophia spp. Habenaria spp., Geodorum densiflorum, and peristylus spp. The edges of the forests have a very luxurious growth of numerous annual and perennial species of Cleome, Desmodium, Alysicarpus, Tephrosia, Crotalaria, Blumea, Cynoglossum, Barleria, leucas, Phyllanthus, Euphorbia, Pupalia, Aerva, Commelina, Cyanotis and sedges and grasses. The species diversity and undergrowth in forests with high proportion of Shorea robusta is comparatively poorer than in the mixed forests. Sal is generally absent on hill slopes. � Tropical Dry Deciduous Forests

These are found in comparatively drier areas, genrally in and around the Chhattisgarh Plains. Though not always conspicuously different from the moist deciduous forests, since transitionary stages are not uncommon, dry deciduous forests are dominated by Legerstroemia parviflora, Butea monosperma, Diospyros melanoxylon, Albizia spp., Anogeissus latifolia, Terminalia spp., Aegle marmelos,

TE-5 Bade Jampali village 2.1 SSW

TE-6 Daramurra village 1.8 SW

The primary data was generated through:

1. Preparing a general checklist of all plants encountered in the study area. This would indicate the biodiversity for wild and cultivated plants. The plants so encountered were classified into life form spectrum according to the classification of Raunkiaer's classification of life form spectrum.

2. Phytosociological studies by using list count quadrate method for woody and

herbaceous flora in forest areas and only herbaceous flora in ambient air quality monitoring locations. Sufficient number of quadrates of 100-m2 size was adopted for study, which is based on the area species curve. The number of quadrates depended on actual field requirements.

3. Herbaceous and woody flora was studied by taking 10 and 20 quadrates at each

location having 100 m2; 4. Determining the bird population of migratory and local birds by taking 10

random readings at every location; 5. Observing mammals, amphibians and reptiles, noting their calls, droppings,

burrows, pugmarks and other signs; and

6. Local inhabitants were interviewed for uses of plants and animals and to get ethnobiological data.

3.8.5.1 Floristic Composition- Primary Survey

� Floristic Richness

• Cryptogamic Vegetation

The area shows many algae, fungi, bryophytes and ferns. Algae are present in aquatic bodies or in marshy places. Fungi, particularly from ascomycetes and basidiomycetes are located on ground or epiphytically. Lichens of crustose, foliose and fruticose types are present on different substrates (Lichens, Ascomycetes and Basidiomycetes could be observed near hilly terrain). Bryophytes occur in wet areas and occasionally on barks of trees and old walls of houses. The commonly observed bryophtes in this area are Funaria sp and Polypodium sp. Fern flora of the study area is insignificant. The aquatic weeds Hydrilla sp, Chara sp, Salvinia, Nymphea were predominant in small ponds in agricultural fields. • Life Form Spectrum

Raunkiaer defined life forms as the sum of adaptations of plants to climate. Braun-

Blanquet (1951), whose system is adapted in this study, modified the Raunkiaer's system. During field survey, maximum 251 plant species (except algae, fungi and bryophytes) were recorded from the study area. Table-1 of Annexure-VII lists all species recorded in the study area. Classwise distribution of lifeforms in the study area is presented in Table-3.8.3.

• Comments on the Life Form Spectrum

Life form spectrum is a reflection of plant community. A plant community is governed by several factors like climatic, edaphic, topographic and biotic. Even local variations in environment affect components of plant community.

In the study area, maximum number of species are phanerophytes (42.23%) followed by therophytes (37.85%). These classes are followed by hemicryptophytes (13.94%) and hydrophytes. Geophytes were found in very few numbers.

Presence of large number of phanerophytes (shrubs and trees) and therophytes (annuals or herbaceous vegetation) indicates semiarid to tropical vegetation structure. Hemicryptophytes (predominantly grasses and sedges) were found to be significant in the area. These indicate fertile and wet soil in upper layer of soil profile. Hydrophytes were present in both the seasonal and perennial water bodies.

3.8.5.3 Endangered Plants

The study area did not record the presence of any critically threatened species. The records of Botanical Survey of India and Forest department also did not indicate presence of any endangered or rare and vulnerable plant species in this area.

3.8.6 Terrestrial Fauna and Ornithology • National Park/Sanctuary As per forest records of Bilaspur review of literature, there are no sanctuaries or national park, Tiger reserves, Elephant reserves, Biospheres, Conservation reserves, and community reserves in 15- km radius from proposed power plant site.

3.8.7 Aquatic Ecosystems

Protecting the environment and making efficient use of natural resources are two of the most pressing demands in the present stage of social development. The task of preserving the purity of the atmosphere and water basins is of both national and global significance since there are no boundaries to the propagation of anthropogenic contaminants in the water. An essential pre requisite for the successful solution to these problems is to evaluate ecological impacts from the baseline information and undertake effective management plan. So the objective of aquatic ecological study may be outlined as follows:

• To characterize water bodies like fresh waters; • To understand their present biological status; • To characterize water bodies with the help of biota; • To understand the impact of proposed industrial and urbanization activities; and • To suggest recommendations to counter adverse impacts, if any on the

ecosystem. In order to get a clear picture and to assess the various parameters of water, two sampling locations were identified for sampling. Samples were collected during study period. The sampling locations are presented in Table-3.8.6 and shown in Figure-3.8.1.

3.8.7.1 Methodology Adopted for Aquatic Studies Two water samples for plankton study were collected in summer season to know the planktonic flora and fauna. The samples were collected at a depth of 0.30 m from surface of the water. The samples were collected in one-liter capacity polyethylene cans and the samples were fixed with 4% buffered formaline solution. For the measurement of frequencies of various forms of phyto-plankton and zoo-plankton, one drop of the sedimented plankton was mounted on a micro slide and as many as 10 different microscope fields situated at more or less even distances from each other were examined and the number of Importance organisms counted (Lackey method, 17th edition, APHA, AWWA 1992). The plankton forms were identified upto species level and Shannon Weaver’s index was calculated. The observed planktonic flora and fauna are presented in Table-3.8.7.

3.8.7.3 Conclusions on Aquatic Ecology

Surface water samples were collected from two surface water sources for analysis of biological parameters. Basillariophycean, Chlorophyceaen, Myxophyceaen, Rotifers and Cladocerans are predominant in the studied water bodies. Plankton diversity Index for phytoplankton and zooplankton varies from 2.85 to 2.56 and 2.52 to 2.16. Physico-chemical, biological parameters and diversity index reveals that the studied water bodies do not indicate any industrial contamination.

3.8.8 Summary Ecological studies were conducted in and around existing industrial and assess to know the biological resources. 251 plant species were identified which are mainly composed of phanerophytes and therophytes, hemicryptophytes. Phytosociological studies were conducted during study at various locations such as forest areas and

near villages areas to assess phytosociological structure in the study. Dominance of Shorea robusta,Madhuca latifolia, Terminalia tomentosa, Adina cordifolia, Pterocarpus marsupium, Ceiba pentandra, Cassia tora, Eupatorium odarattum, Parthinium hystreophorus, Blumea for woody and herbal populations in the plant site. The wide variety of herbaceous members and presence of wide variety of woody members reflects that the study area is a un-distrurbed ecosystem. Marginal differences were observed in the dominant species in the forest and in non-forest areas. The dominance of herbaceous flora is due to southwest monsoon rains and fertility of soil. 83 animal species were recorded/ observed during study period. It can be concluded that there are about 3 animals species which belong to Sch-I, 7 species which belong to Sch-II and rest of species belong to Sch-III, Sch-IV and Sch-V of Wildlife Protection Act, 1972.

may either be fallows or covered with shrubs, which are not put to any use. The study area comprises of 4813.0 ha cultivable wastelands, which works out to about 16.4% of the total area. This percentage of land in this category indicates that almost all the cultivable lands are used for cultivation as well as various other purposes, while leaving a very less extent of land un-cultivated.

3.9.4 Land not available for Cultivation All the lands not included in the above categories of land uses are considered in the category of land not available for cultivation. This category of land use mainly consists of the hilly and barren lands, human settlements, roads, water-bodies, etc. About 5938.0 ha area working out to about 19.0% of the total study area falls in this category.

3.9.5 Land Use Pattern based on Remote Sensing Data Remote sensing satellite imageries were collected and interpreted for the 10-km radius study area for analyzing the land use pattern of the study area. Based on the satellite data land use/ land cover maps have been prepared.

3.9.5.2 Data Requirements

IRS-P6 Geo-Coded FCC on 1:1,45,000 scale of LISS-III was acquired for 27th December, 2007 and was used for the mapping and interpretation. Besides, other collateral data as available in the form of maps, charts, census records, other reports and especially topographical survey of India maps are used. In addition to this, ground truth survey was also conducted to verify and confirm the ground features.

3.9.5.3 Methodology

The methodology adopted for preparation of land use/ land cover thematic map is monoscopic visual interpretation of geocoded scenes of IRS-P6 satellite LISS-III and field observations are taken. The various steps involved in the study are preparatory field work, field survey and post field work.

3.9.5.4 Pre-field Interpretation of Satellite Data

The False Color Composite (FCC) of IRS-P6 satellite data at 1:1,45,000 scale are used for pre-field interpretation work. Taking the help of topo-sheets, geology, geomorphology and by using the image elements the features are identified and delineated the boundaries roughly. Each feature is identified on image by their image elements like tone, texture, colour, shape, size, pattern and association. A tentative legend in terms of land cover and land use, physiography and erosion was formulated. The sample areas for field check are selected covering all the physiographic, land use/land cover feature cum image characteristics.

• Ground Truth Collection

Both topo-sheets and imagery were taken for field verification and a transverse plan using existing road network was made to cover as many representative sample areas as possible to observe the broad land use features and to adjust the sample areas according to field conditions. Detailed field observations and investigations were carried out and noted the land use features on the imagery.

• Post Field Work

The base maps of the study area were prepared, with the help of Survey of India Topo-sheets on 1:1,45,000 scale. Preliminary interpreted land use and the land cover features boundaries from IRS-P6 False Colour Composite were modified in light of field information and the final thematic details were transferred onto the base maps. The final interpreted and classified thematic map was catrographed. The cartographic map was colored with standard colour coding and detailed description of feature with standard symbols. All the classes noted and marked by the standard legend on the map.

3.9.5.5 Final Output

The final output would be the land use/land cover map on 1:1,45,000 scale, numerals were given different colour code for each category as shown in map. Area estimation of all features of Land use/Land cover categories was noted.

study area works out to be 36.5%.The female literacy rate, which is an important indicator for social change, is observed to be 53.4% in the study area. This indicates that there is a considerable need for sociological development in the region.

3.10.5 Occupational Structure

The occupational structure of residents in the study area is studied with reference to main workers, marginal workers and non-workers. The main workers include 4 categories of workers defined by the Census Department consisting of cultivators, agricultural laborers, those engaged in manufacturing, processing and repairs in household industry; and others including those engaged in household industry, construction, trade and commerce, transport and communication and all other services.

The marginal workers are those workers engaged in some work for a period of less than six months during the reference year prior to the census survey. The non-workers include those engaged in unpaid household duties, students, retired persons, dependents, beggars, vagrants etc.; institutional inmates or all other non-workers who do not fall under the above categories. As per 2001 census records altogether the main workers works out to be 31.4% of the total population. The marginal workers and non-workers constitute to 11.6% and 57.1% of the total population respectively. The distribution of workers by occupation indicates that the non-workers are the predominant population. The occupational structure of the study area is given in Table-3.10.4.

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-1

4.0 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

4.1 Introduction

The chapter presents identification and appraisal of various impacts due to the

proposed power plant during construction and operational phases. The

environmental impacts are categorized as primary or secondary. Primary impacts

are those, which are attributed directly to the project and secondary impacts are

those, which are indirectly induced and typically include the associated

investment and changed pattern of social and economic activities by the proposed

action.

The mitigation measures proposed for minimizing the impacts have also been

discussed in this chapter. Environment Management Plan (EMP) is developed to

minimize adverse impacts and to ensure that the environment in and around the

project site is well protected. The EMP has been prepared for both construction

and operation phases of the proposed facilities.

The impacts have been assessed for the power plant assuming that the pollution

due to the existing activities has already been covered under baseline

environmental monitoring and continue to remain same till the operation of the

project.

The construction and operational phase of the proposed project comprises various

activities each of which may have an impact on some or other environmental

parameters. Various impacts during the construction and operation phase on the

environment have been studied to estimate the impacts on the environmental

attributes and are discussed in the subsequent sections.

4.2 Impacts during Construction Phase

This includes the following activities related to land acquisition, leveling of site,

construction of related structures and installation of related equipment.

4.2.1 Impact on Land Use

The land identified for the proposed 4x300 MW power plant is about 960-acre.

About 310-acre of the land will be used for ash disposal. Main plant facilities and

ancillary facilities will occupy 550-acre of land.

The proposed plant land is mostly barren land and dry single crop agriculture

land.

This land is under the government (18.3%) and private (81.7%) ownership and

there is no forest or ecological sensitive land within proposed site. No residential

or habitation areas are proposed to be acquired, hence no displacement of

residential areas. The agricultural area in the proposed plant site does not have

any irrigation system and is only rain-dependent. Hence, no major loss of

agricultural productivity is envisaged.

Page 99: ENVIRONMENTAL IMPACT ASSESSMENT ... Impact Assessment for the Proposed 4x300 MW Coal Based Thermal Power Plant at Binjkot, Darramura, Badejampali and Gindola Villages in Kharsia Tehsil

Environmental Impact Assessment for the proposed 4x300 MW Coal based Thermal Power Plant at Binjkot, Darramura, Badejampali and Ggindola Villages in Kharsia Tehsil of Rraigarh District, Chhattisgarh State

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-2

Construction of plant will lead to permanent change in land use pattern at the site

as a direct impact. The proposed project involves construction of large scale civil

works including levelling within project premises. The earthen material generated

during construction of large scale water storage reservoirs within the project

premises will be used for level rising of plant area.

The environmental pollution impacts during constructional phase would be

temporary and are expected to gradually stabilize by the time of commissioning

of proposed project.

The buffer zone of the proposed plant site is sparsely distributed villages. There

are no sensitive locations such as archaeological monuments, sanctuaries,

national parks, critical pollution zones etc within 10-km radial distance around the

proposed project site, except the reserved forest patches on hilltops. No major

changes in land use pattern of study area (region) will occur due to the project

activities.

Hence, no major impact is envisaged on land use pattern of the project site or

buffer zone.

4.2.2 Impact on Soil

All major construction activities tend to create certain changes in the soil of the

area. Excavation denudes the topsoil and makes it loose. Destruction of topsoil

leads to reduction of fertility and removal of vegetation cover with associated

hazards of the soil erosion.

During storms, some of the excavated soil and construction material such as sand

etc. would be blown up in the air and dispersed around the project site, some would

also tend to be driven into the soil and clog inter-granular spaces. However, in order

to minimise such impacts, appropriate soil conservation measures would be

undertaken. Vegetation cover would also be replaced by planting and turfing

wherever feasible. No adverse impacts on soil in the surrounding area are

anticipated.

4.2.3 Impact on Topography

The proposed project premise is a generally plain land with a general elevation of

about 230-m above MSL. Most of the buffer zone of the project is flat land.

It is proposed to level the project area and to use the earthen material excavated

from the proposed reservoir sites inside the premises. There will be no tall

structures except stacks. Also, the contours of natural drainage will not be

disturbed.

In view of the above, there will be no major adverse impact on topography of the

project site.

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-3

4.2.4 Impact on Air Quality

Particulate matter would be the predominant pollutant affecting the air quality

during the construction phase. The soil of the project area is likely to generate

considerable quantities of dust, especially during dry condition. Dust will be

generated mainly during excavation, back-filling and hauling operations along

with transportation activities. However, the wind velocity in the area is not very

high. Wind blown dust is not expected to have tangible effects. The power plant

compound to a height of about 3.0m above the ground level will act as a barrier

to wind blown dust.

Access roads will be given suitable surface treatment to minimise dust

generation. Sprinkling of water from water tankers or other suitable means would

be undertaken at the construction site for suppression of fugitive dust.

Undesirable gaseous pollutants will be generated mostly by the automobile traffic.

However, this would not lead to any tangible effect, as the expected traffic

volume is low.

It would be ensured that all vehicles plying during construction are properly

turned and maintained to keep emissions within the permissible limits.

4.2.5 Impact on Water Quality

Impact on water quality during construction phase may be due to non-point

discharges of solids from soil loss and sewage generated from the construction

workforce stationed at the site. However, due to the construction being carried out

on generally plain terrain, the soil losses will be negligible. Further, the construction

will be more related to mechanical fabrication, assembly and erection; hence the

water requirements would be small. The construction water requirement will be met

by proposed bore wells in the plant site. Temporary sanitation facilities (septic tanks

and soak pits) will be set-up for disposal of sanitary sewage generated by the

workforce.

The overall impact on water environment during construction phase due to proposed

project is likely to be short term and insignificant.

4.2.6 Impact on Noise Levels

Heavy construction traffic for loading and unloading, fabrication and handling of

equipment and materials are likely to cause an increase in the ambient noise levels.

The areas affected are those close to the site. However, the noise will be temporary

and will be restricted mostly to daytime.

The noise control measures during construction phase include provision of caps on

the equipment and regular maintenance of the equipment.

4.2.7 Impact on Terrestrial Ecology

The initial construction works at the project site involves land clearance. During

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-4

construction vegetation may be disturbed. Greenbelt will be developed phase wise

during construction to improve the aesthetic value in the area and to screen out the

fugitive dust generated during construction.

The removal of vegetation from the soil and loosening of the topsoil generally

causes soil erosion. However, such impacts will be confined to the project site and

will be minimized through paving and water sprinkling.

There are not many existing matured trees in the site. However, greenbelt will be

developed surrounding the plant facilities. The existing trees will be preserved to the

extent possible. Thus, no major adverse impacts are envisaged on terrestrial

ecology.

4.3 Impacts during Operational Phase

The proposed plant operation will involve 1200 MW of power generation. The

following activities related to the operational phase will have varying impacts on

the environment and are considered for impact assessment:

• Topography and climate;

• Air environment;

• Water resources and quality;

• Land use;

• Soil quality;

• Solid waste;

• Noise levels;

• Terrestrial and aquatic ecology;

• Demography and socio-economics; and

• Infrastructural facilities.

4.3.1 Topography and Climate

Most of the area of the plant site is plain and it will be maintained even during post-

project scenario. There will not be any topographical changes during operation of

the project.

Heat loss through stack will be about 6 to 7% of the total heat input to the boiler.

The quantum of heat so lost to the atmosphere is not significant. The moderate

wind speed and rainfall in the region will mitigate the adverse impacts. The

vegetation in the region will help to manage the thermal balance.

4.3.2 Impact on Air Quality – Point Emission Sources

Being a coal based power project, Suspended Particulate Matter (SPM), Sulphur

dioxide (SO2) and Oxides of Nitrogen (NOx) will be the important air pollutants

from the proposed project.

Prediction of impacts on air environment has been carried out by employing

mathematical model based on a steady state gaussian plume dispersion model

designed for multiple point sources for short term. In the present case, Industrial

Source Complex [ISC3] 1993 dispersion model, designed for multiple point

sources for short term and developed by United States Environmental Protection

Agency [USEPA] has been used for simulations from point sources.

The model simulations deal with dispersion of three major pollutants viz., Sulphur

Dioxide (SO2), Oxides of Nitrogen (NOx) and Suspended Particulate Matter (SPM)

emitted from the stacks.

4.3.2.1 Model Input Data

The air pollution modelling has been carried out representing the worst case

scenario. The stack details considered for model computations are summarized in

• Meteorological Data

The hourly meteorological data recorded at site is converted to the mean

meteorological hourly data as specified by CPCB and the same has been used in

the model. In absence of site specific mixing heights, mixing heights published in

‘Spatial Distribution of Hourly Mixing Depths over Indian Region’ by

Dr. R.N.Gupta have been used.

4.3.2.2 Presentation of Results

The model simulations were carried out for summer season. For the Short-term

simulations, the Ground Level Concentrations (GLCs) were estimated around 1200

receptors to obtain an optimum description of variations in concentrations over the

site in 10-km radius covering 16 directions.

The maximum incremental ground level concentrations and resultant concentrations

for SPM, SO2 and NOx are given in Table-4.2 and Table-4.3 respectively.

Similarly, the isopleths for various pollutant concentrations are enclosed. The CPCB

permissible ambient air quality standards are given in Table-4.4.

4.3.2.3 Discussions on Results of Assessment

A perusal of previous sub-section reveal that the maximum incremental short-term

24 hourly ground level concentrations for Particulate Matter, SO2 and NOx likely to

be encountered in the operation of the power project are 2.3, 31.5 and 23.9 µg/m3

respectively occurring at a distance of about 2.8-km in the south west direction.

The maximum resultant 24 Hourly concentrations for SPM, SO2 and NOx after

implementation of the proposed project (4X300MW power project) are 141.9, 44.9

and 39.5 µg/m3 respectively.

According to the above presented results, it can be stated that the impact of SPM

from proposed 4X300MW power plant would be negligible in core or buffer zone

of the project.

Even though, the incremental and resultant concentrations of SO2 and NOx are

significant to certain extent, they are well within the NAAQ limits and hence, the

AAQ levels after implementation of the proposed 4X300 MW power project will

remain within the permissible limits.

It is also to be noted that the above concentrations are for worst case scenario of

operations only. For indigenous fuel consumption, the concentrations will be much

lower. Hence, it can be stated that the AAQ of the area will be within the

permissible limits of respective zones.

Air dispersion modeling studies have been carried to assess the impact on forest

blocks and sensitive location in study area. The details are presented in Table-

4.3.3 Impact on Air Quality - Fugitive Emissions

The fugitive dust emissions expected are from coal storage yards, coal conveyor

belt area, ash dumping areas, transportation of fuel and solid waste.

In the proposed project coal handling plant will be properly operated with EMP

suggested in this report, no major fugitive dust emissions are envisaged.

Similarly, Lean slurry disposal system of ash stacking will be practiced and hence,

no dust emissions are envisaged from ash dump areas. The fuel will be received

through rail line and the solid waste will be sent to dyke areas through pipeline.

Hence, no dust emissions from transportation are envisaged. However, internal

roads are to be asphalted to further reduce fugitive dust emissions.

The dust emissions, if any, from the above areas will be fugitive in nature and

maximum during summer season (when the wind velocities are likely to be high)

and almost nil during the monsoon season. The dust emissions are likely to be

confined to the place of generation only. The quantification of these fugitive

emissions from the area sources is difficult as it depends on lot of factors such as

dust particle size, specific gravity of dust particles, wind velocity, moisture content

of the material and ambient temperatures etc. Also, there is a high level of

variability in these factors. Hence, these are not amenable for mathematical

dispersion modelling. However, by proper usage of dust suppression measures,

dust generation and dispersions will be reduced.

4.3.4 Impact on Water Resources and Water Quality

Water is required for various power plant operations and the water balance has

been explained in Chapter-2 under Section-2.4.3 and Section-2.7.2.

No groundwater source will be tapped for meeting the water requirements during

operation of the power plant. The water requirement of the project will be met

from Mahanadi River.

4.3.4.1 Impact on Water Resources

The required water for regular operations of the plant will be about 35 MCM

Irrigation department of Chhattisgarh govt has indicated the availability of

sufficient water in the river. It is possible to fulfil the requirement of the proposed

power plant sufficiently. The copy of the letter from the Irrigation Department is

enclosed in Annexure-III.

Similarly, as no groundwater source is proposed to be tapped for meeting the

water requirements during operation of the power plant, no impacts on

groundwater resources is envisaged.

4.3.4.2 Impact on Water Quality

The water balance and wastewater generation details have been described in

Chapter-2. Total wastewater (including domestic wastewater) generation of entire

project (4X300 MW) in the project will be about 688-m3/hr, in that treated water

will used for ash handling plant, coal handling plant and green belt.

Garland drains around the ash pond site will be provided for the collection of run-

off water during monsoon season.

The storm water in the project area will be collected through storm water drains

and collected in the storm water tank, which is lined to prevent any

contamination of ground water. The stored storm water will be utilized in the

plant operation resulting in conservation of fresh water. Suitable rain water

harvesting pits will be provided along the storm water drain to recharge the

ground water table. In case the storm water tank starts overflowing, the same

will be discharged into nearby nalla.

Various types of wastewater to be generated in the proposed project with their

quantity, expected pollutants and treatment proposed are given in Table-4.6.

Total wastewater (including domestic wastewater) generation of entire project

(4X300 MW) in the project will be about 688-m3/hr, in that treated water will

used for Ash handling plant, coal handling plant and green belt.

4.3.5 Impact on Land Use

The land identified for the proposed 4x300 MW power plant is about 960-acre.

About 310-acre of the land will be used for ash disposal. Greenbelt including

green cover will be developed in an area of about 137.5-acre, which works out to

about 1/3rd of the main plant area.

After commissioning of proposed plant, this land use will change to industry

category. The greenbelt proposed will have a positive impact on land. There will be

minimum changes in land use during the operational phase of the project. Hence,

no major impacts are envisaged during operational phase of the project.

4.3.6 Impact on Soil

Most of the impacts of power plant project on soils are restricted to the construction

phase, which will get stabilized during operational phase. The impact on the topsoil

will be confined to the proposed main plant area only. Further, the greenbelt

proposed will have a very positive impact on soil quality.

The probable sources of degradation of soil quality will be due to generation &

disposal of ash and fugitive dust emissions. However, the impacts due to disposal of

ash are covered under Section-4.3.8.

The airborne fugitive dust from the plant is likely to be deposited on the topsoil in

the immediate vicinity of the plant boundary. However, the fugitive emissions are

likely to be controlled to a great extent through proposed control measures like

water sprinkling and development of greenbelt development.

Hence, no major impact is envisaged on soil quality of the project site.

4.3.7 Impact of Solid Waste

Ash is the major solid waste to be generated from the proposed coal based power

plant. Coal consumption of 6.02 MTPA was considered for estimation of ash

generation. Ash will be generated as both forms viz. bottom ash and fly ash.

About 80% of the total ash generation will be fly ash and remaining 20% comes

as bottom ash. The fly ash is the important air pollutant, which emits to outside

environment through stacks attached to boilers. ESP’s with >99.95% efficient

shall be provided to prevent ash dispersions into ambient air. The details of the

solid waste generation are given in Table-4.8.

It is proposed to collect fly ash from ESP hoppers in dry from and provide/supply

to potential ash users depending on the demand. The balance unutilized ash will

be disposed off using Lean Slurry Disposal technology. An area of about 310

acres has been identified for ash pond within the project premises. In view of the

proposed Lean Slurry ash disposal technology, the impact of ash pond

supernatant runoff would not be expected and the impacts on surrounding

environment would be insignificant. However, it is also proposed to provide the

ash pond with an impervious HDPE layers.

The sludge from sewage treatment plant will be dried, vermi-composted and used

as manure for greenbelt maintenance. Canteen/sanitary waste will be composted

and used as manure for greenbelt development.

With the implementation of above precautionary measures, the impacts due to

solid waste disposal will be minimum.

•••• Impact of Ash Pond on Surface Water

In ash disposal, Lean Slurry Disposal method will be adopted. The bottom ash

slurry and fly ash slurry from the both the units will be led to common slurry sump

of the combined ash slurry disposal pump house. In view of the proposed Lean

Slurry ash disposal technology, the impact of ash pond supernatant run off would

not be expected. Hence, the impact of the ash pond on the surface water will be

insignificant.

•••• Impact of Ash Pond on Ground Water

The possibility of groundwater contamination due to the leaching of metals from

the ash pond will be examined based on soil investigation study. The dykes around

Page 112: ENVIRONMENTAL IMPACT ASSESSMENT ... Impact Assessment for the Proposed 4x300 MW Coal Based Thermal Power Plant at Binjkot, Darramura, Badejampali and Gindola Villages in Kharsia Tehsil

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-15

the pond will be constructed with proper compaction at maximum dry density. The

co-efficient of permeability will be much less than the natural deposits to further

reduce the drainability. However, with the passage of time, more and more fly ash

particles will get deposited in the pore spaces of the top soil making it essentially

non-porous and impervious and in view of the above, contamination through

leaching is not envisaged. However, it is also proposed to provide the ash pond

with an impervious bottom HDPE layers.

In view of the above mitigative measures, no surface water or groundwater

pollution is anticipated from the ash disposal area. Similarly, as the other solid

wastes also used properly, no impact of solid waste is envisaged.

4.3.8 Impacts on Ecology

Detailed flora and fauna studies were carried out during study period and the

details are presented in Section-3.8 of Chapter-3. About 251 plant species were

identified and these are commonly growing plant species of the region. As per

records of forest department of Raigarh, literature survey and also from field

studies, there are no endangered, threatened and protected plants. 82 animal

species were recorded/reported from study area during study period, out of which 3

species belongs to Sch-I, 7 species belong to Sch-II, 3 species belongs to Sch-III

and rest of the species belongs to Sch-IV and Sch-V as per Wildlife Protection Act,

1972.

It is proposed to develop greenbelt with an average width of about 50-m to 100-

m around plant site and implementation of eco development along with local

people will enhance the greenery of the area. Hence, no significant adverse

negative impact is envisaged on terrestrial ecology.

The impacts on aquatic ecology due to proposed project would be negligible as the

treated effluents from the proposed power project will meet the prescribed

standards prior to final discharge.

Similarly, as the discharge water will not have much higher temperature than the

receiving body, no thermal effects on receiving body due to discharge are

envisaged.

Hence, minimal impact is envisaged on the ecology of the area.

4.3.9 Impact on Noise Levels

The main noise generating stationary sources from the power plant will be

pumps, compressors along with cooling tower and boilers. The noise levels at the

source for these units will be in the range of 80-90 dB(A). The noise dispersion

from the plant units has been computed based on the mathematical model. The

major noise generating sources from the proposed plant are identified and listed

in Table-4.9. These are considered as input to the noise model.

4.3.9.1 Presentation of Results

The incremental noise levels are computed at proposed project site at 100-

mX100-m grid intervals over an area of 10-kmX10-km study area. The predicted

results of incremental noise levels at each grid points are used to draw noise

contours. The predicted noise contours around proposed sources are shown in

Figure-4.4. As per the predicted results, noise levels at the plant boundaries are

given below in Table-4.10.

TABLE-4.10

PREDICTED NOISE LEVELS AT THE PLANT BOUNDARIES

1 N 32

2 NE <30

3 E <30

4 SE <30

5 S <30

6 SW <30

7 W 30

8 NW 30

The predicted noise levels at the boundary due to various plant activities will be

ranging in between <30 to 32 dB (A). The incremental noise levels will be less

than 40 dB(A) at all the surrounding habitations. It is seen from the simulation

results that the incremental noise levels will be well within the CPCB standards.

4.3.9.2 Impact on Work Zone

Boilers and cooling towers are the high noise generating equipments in the

proposed power plant. However, impacts on the working personnel are not

expected to be significant on account of the high level of automation of the plant,

which means that workers will be exposed for short duration only and that too

intermittently.

The noise generation during operational phase would be at source itself through

different measures such as inspection, operation and maintenance at regular

intervals. The noise control measures as described in EMP will be fully followed.

The occupational noise exposure to the workers in the form of 8-hourly time

weighted average will be maintained well within the prescribed OSHA standards

(<90 dB(A)). Hence, the impact on occupational health of workers would be

insignificant.

VIMTA Labs Limited, Hyderabad C4-18

4.3.9.3 Impact on Community

As per the location of power plant, the minimum distance available between

proposed major noise sources and the outer periphery of the project site would

be more than 500-m. The cumulative incremental impact of all noise sources at

boundary will range in between <30dB (A) to 32 dB (A). The effective increase of

incremental noise contours at the boundary would be only about 1.5 to 2.5 dB

(A). The nearest human habitations are located at about 0.6-km from the

boundary and the cumulative noise impacts would be insignificant.

4.3.10Prediction of Impacts on Socio-Economics

No shifting of human habitations is envisaged for setting of the proposed power

plant. Hence, no Resettlement activities are required to be carried out.

The requirement of unskilled manpower will be met from nearby villages during

construction phase. The project will also help in generation of the indirect

employment apart from direct employment. This will be a positive socio-economic

development for the region. There will be a general upliftment of standard of

living in the region.

4.3.11 Impacts on Public Health and Safety

The discharge of waste materials (stack emission, wastewater and solid wastes)

from process operations may have potential impact on public safety and health.

The wastewater generated from power plant will be treated before discharging

outside. It is proposed to reuse the wastewater to the maximum extent. Since,

the adverse impacts on ambient air and soil quality are predicted to be low it is

anticipated that with effective implementation of control measures suggested for

pollution control, the impact on public health will be minimum.

4.4 Environment Management Plan during Construction Phase

During construction phase, the construction activities like site levelling, grading,

transportation of the construction material cause various impacts on the

surroundings. However, the constructional phase impacts are temporary and

localised phenomena except the permanent change in local landscape and land use

pattern of the project site.

4.4.1 Land Environment Management

Preparation of site will involve excavations and fillings. The earthen material

generated during excavations and site grading periods, shall be properly dumped

and slope stabilisation shall be taken. The topsoil generated during construction

shall be preserved and reused for plantations.

No nallas of water courses are present in the project site. The river is at about 0.5-

km from the project facilities. However, natural drainage pattern shall not be

disturbed as far as possible.

4.5.3.1 Rainwater Harvesting Facilities

Groundwater Recharge with Rain Water Harvesting

There is generation of surface run-off from the plant facility during monsoon

season. The run-off will be of two types, i.e., run-off from the pervious area of

the facility site and run-off from the built-up area of the facility.

•••• Run-off from the Built-up Areas

The run-off from the paved surfaces of the proposed facility will be routed

through a carefully designed storm water drainage network and collected in storm

water collection sump and excess rainwater will be discharged to bore wells

constructed on these internal drains.

•••• Run-off from the Pervious Area

The run-off from the pervious area will be routed directly to the rainwater

harvesting structures constructed at suitable locations as per the contours.

For augmenting the ground water resources in the plant premises, number of

rainwater harvesting pits will be constructed and the internal drains where excess

rain water flowing in drain will be diverted to these pits. These structures will

facilitate percolation of water into the ground and thus augmenting the

groundwater sources. The roof top water will be routed to the storm drains. This

will result in increase in groundwater tables and to some extent the improvement

of ground water quality.

The size and the locations of rainwater harvesting pits will be decided during

detailed engineering of the project.

Run off from the proposed project site is calculated using rational formula:

Q = C x I X A

Q = Run-off in m3/hr

A = Catchment Area (ha)

C = Coefficient of Run-off

I = intensity of Rainfall in mm/hr

Total area = 388.5-ha

Intensity of Rainfall (I) = 2.5 cm/hr (1 inch/hr)

Run-off co-efficient (C) = 0.7

Q = 0.7 x (2.5/100) m/hr x (388.5 x 10000) m2

= 67987.5m3/hr

4.5.3.2 Storm Water Management

The power plant water management system will be designed to minimize the

potential for storm water contamination occurring at the site. This will be

achieved by incorporating the following features into the storm water

management system:

Page 121: ENVIRONMENTAL IMPACT ASSESSMENT ... Impact Assessment for the Proposed 4x300 MW Coal Based Thermal Power Plant at Binjkot, Darramura, Badejampali and Gindola Villages in Kharsia Tehsil

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-24

• Run-off from upstream areas will be diverted around the plant site;

• The quantity of contaminated run-off generated will be minimized by diverting

run-off from areas external to the plant to storm water discharge points;

• Hazardous material and fuel storage areas will be bunded and drains will be

provided to around these facilities to prevent entering of run-off water; and

• Run-off from area external to process areas of the plant will be contained

within a storage system.

4.5.4 Noise Pollution Management

In the process, various equipments like pumps, cooling tower, compressors etc

generate the noise. The recommendations to mitigate higher noise levels are:

• Equipments should be designed to conform to noise levels prescribed by

regulatory authorities;

• Provision of acoustic barriers or shelters in noisy workplaces;

• Provision of hoods to noise generating equipments like pumps;

• Provision of thick greenbelt to attenuate the noise levels;

• Provision of Personal Protective Equipments (PPE) such as earplugs, earmuffs to

the workers working in high noise level area; and

• Implementation of greenbelt, landscaping with horticulture at power block areas

to reduce noise impacts.

4.5.5 Solid Waste Management

Solid waste in the form of ash will be generated in a coal based thermal power

plant. The total ash generated in the plant will be 2.47 MTPA out of which 20%

will be bottom ash i.e. 0.49 MTPA and balance will be fly ash of 1.98 MTPA. The

following measures shall be taken for solid waste management:

• In general ash will be given to potential ash users;

• The excess ash will be disposed off using lean slurry disposal system to HDPE

lined ash pond;

• The generated waste oil shall be explored to be used in boiler furnace with HFO

or shall be given to authorized recyclers;

• The organic portion of solid waste generated in the Sewage Treatment Plant

(STP) will be used as manure in greenbelt development; and

• Maintaining the data base on solid waste generation such as quantity, quality,

treatment/management.

4.5.5.1 Literature on Fly Ash Utilization

• Fly Ash use in Cement Industries

Cement mixed with fly ash is known as Portland Pozzolana Cement (PPC). As per

the Indian standards, fly ash can be used to replace 25% cement. The fly ash

cement is made by grinding with clinker. The fly ash generated from proposed

power plant will be supplied to cement plants in the region. The fly ash can be

utilized by these cement plants to manufacture PPC cement.

• Fly Ash use as Micro-Nutrient in Fertilizer

Ash is a good fertilizer due to the presence of heavy metal traces, which act as

micro-nutrients to the vegetation and give good yield of agricultural produce.

It is estimated that the application of 1 to 2 tonnes of ash per hectare of land will

increase the yield of the crops by 30%. Fly ash can be applied approximately on

2000 ha of agricultural land.

• Fly Ash use in Road Construction

Fly ash can be used as a component in a stabilized aggregate sub-base course. A

blend of 84% dense aggregate, 11% pond fly ash and 5% hydrated lime gives

maximum dry density, optimum moisture content and unconfined compressive

strength.

4.5.5.2 Prospective Ash Utilization

It is very much clear that the ash generated at the power plants can be

effectively used for various products. Though the acceptability of the ash-based

products may take a long time, it is always better to start on a small scale.

4.5.5.3 Policy on Fly Ash Utilization

Utilization of ash produced by coal based power stations as a thrust area of its

activities and all possible actions will be taken to enhance level of ash utilization.

Page 123: ENVIRONMENTAL IMPACT ASSESSMENT ... Impact Assessment for the Proposed 4x300 MW Coal Based Thermal Power Plant at Binjkot, Darramura, Badejampali and Gindola Villages in Kharsia Tehsil

Chapter-4 Anticipated Environmental Impacts and Mitigation Measures

VIMTA Labs Limited, Hyderabad C4-26

In the proposed power plant, various avenues for ash utilization will be explored

as delineated in the above sections. In particular, supply of quality ash for

manufacture of cement will be taken as there are some cement units. Some of

the actions planned for the project are as given below:

• SKS Power Generation (Chhattisgarh) Limited will make efforts to motivate

and encourage entrepreneurs to set up units for manufacture of ash-based

products such as fly ash bricks, lightweight aggregates, and cellular concrete

products etc as ancillary industries in the region. SKS Power Generation

(Chhattisgarh) Limited would be providing all possible infrastructure facilities

to these entrepreneurs in accordance with its policy;

• SKS Power Generation (Chhattisgarh) Limited would also continue to

encourage utilization of available ash based products in all its construction

activities; and

• SKS Power Generation (Chhattisgarh) Limited will encourage the use of water

treated fly ash as a soil ameliorator and as a source of micro-nutrients and

secondary nutrients for improving agricultural productivity.

4.5.5.4 Conclusion

All efforts will be made for maximum utilization of ash. However, after reviewing

various proposals of the ash utilization, 40-70% of ash utilization is possible at

the initial period and same will be improved over the period of time in future. SKS

Power Generation Limited is committed to explore possibilities for ash utilization

considering new technologies and avenues and try to achieve the target fixed by

MoEF in this regard.

SKS Power Generation Limited is committed to comply with the Fly Ash

Utilization Notification, 1999 and as amended thereof.

4.5.5.5 Fly Ash Disposal

The balance ash after utilisation shall be disposed in ash ponds. Ash disposal system

proposed is Lean Slurry Disposal. Treated wastewater will be used in ash handling

plant. The ash pond will be provided with HDPE liners. The area provided for ash

pond is about 310-acre.

The major advantages of the Lean Slurry Disposal method are:

• Very low water consumption;

• The slurry can be self-setting and self limiting so that ash will deposit and dry

by itself to form a hard surface;

• Considerably less area is required for ash disposal;

• Specific energy consumption in pumping and transportation will be much

lower;

• Pipeline diameter can be much smaller and transportation velocities could also

be considerably lower due to the fact that the slurry is non-settling. This could

also reduce wear in the pipeline;

VIMTA Labs Limited, Hyderabad C4-27

• Both bottom ash and fly ash can be disposed together if needed; and

• The trenches will be constructed along the periphery of the ash pond to collect

the run-off water during rainy days. The run-off water will be routed through

sedimentation tank before discharging into nalla.

The ash will be utilized in various construction materials to the maximum extent and

100% utilization will be achieved.

4.6 Greenbelt Development

With rapid industrialization and consequent deleterious impact of pollutants on

environment, values of environmental protection offered by trees are becoming

clear. Trees are very suitable for detecting, recognizing and reducing air pollution

effects. Monitoring of biological effects of air pollutant by the use of plants as

indicators has been applied on local, regional and national scale. Trees function as

sinks of air pollutants, besides their bio-esthetical values, owing to its large

surface area.

The greenbelt development not only functions as foreground and background

landscape features resulting in harmonizing and amalgamating the physical

structures of the plant with surrounding environment, but also acts as pollution

sink. Thus, implementation of afforestation program is of paramount importance.

It will also check soil erosion, make the ecosystem more complex and functionally

more stable and make the climate more conducive.

Greenbelt with a width of 50-m to 100-m will be developed around the plant site.

The total greenbelt around the power plant complex will be about (137.5-acre)

which works out to about 1/3rd of total project area including green belt in the

town ship.

In the proposed greenbelt about 343750 trees will be planted with a density of

2500 trees/acre. A capital cost of Rs. 1.0 Crore and an annual budget of Rs.2.0

Crore will be earmarked for this purpose. The plantation schedule will be

completed within five years from the construction period of the project. The

plantation schedule is given in Table-4.12.

Analysis of Alternatives for Technology and Project Site

VIMTA Labs Limited, Hyderabad C5-1

5.0 ANALYSIS OF ALTERNATIVES FOR TECHNOLOGY AND PROJECT SITE

5.1 Analysis of Alternative Technology

The selection of the proper steam generator technology is a critical step in the

basic design of a new power project. The fuel to be fired and the steam cycle to

be adopted dictates the type of steam generator needed to satisfy the

requirements of the project.

5.1.1 Alternatives for Boiler Technology

The following are the general options for selection of boiler technology:

For easy to burn fuels, such as bituminous coals - Suspension firing of the

pulverized fuel in horizontal, wall-mounted burners is the configuration of choice.

For low volatile, low reactivity fuels, such as anthracite and petroleum cokes, the

down-fired arch furnace is the choice adopted world-wide.

Another option for difficult fuels, as well as for waste fuels, which cannot be

properly burned with suspension firing, is the circulating fluidized bed (CFB)

boiler. Also the flywheel of circulating solids in the CFB boiler allows a wide range

of fuels to be fired in the same unit. Super critical boilers for low colorific value

coals are yet to be established with Indian coal firing.

In the proposed project, coal will be the main fuel. Hence, pulverized sub critical

boilers are considered.

5.1.2 Alternatives for Boiler Parameters

Two options, sub-critical and supercritical parameters were examined related to

power generation of thermal power plants.

As the latest supercritical boilers are new in India, Power Consultants in our

country are yet to be geared up for consultancy services to super-critical boilers

due to inadequacy of knowledge and experience base.

The advantages of super critical boilers over sub-critical boilers are the Rankine

cycle efficiency. However, the cycle efficiency is dependent on the condenser

cooling water temperature. In Indian conditions, the cooling water temperature

generally remains on higher side. Hence, the total envisaged efficiency gained by

utilizing super-critical boilers is limited by condenser cooling water temperature.

In super critical boilers for better heat transfer, the boiler tubes are made-up of

marginal section than the sub-critical boilers. With the high ash content (42%) in

Indian coal the erosion pattern envisaged is more therefore the chances of tube

failure in super critical boilers is more as compared to sub- critical boilers

designed for Indian coals. Thus, the availability will be less. The relatively lesser

thick tubes, superior metallurgy with highest cost used in the super critical boilers

can lead to fast erosion or even abrupt damage of boiler tubes, because of

Page 132: ENVIRONMENTAL IMPACT ASSESSMENT ... Impact Assessment for the Proposed 4x300 MW Coal Based Thermal Power Plant at Binjkot, Darramura, Badejampali and Gindola Villages in Kharsia Tehsil

Kharsia Tehsil of Raigarh District, Chhattisgarh State

Chapter-5

Analysis of Alternatives for Technology and Project Site

VIMTA Labs Limited, Hyderabad C5-2

frequent tendency of imbalance in furnace heat absorption. This is consequent to

unpredictable raise in temperature at Super heater/ Reheater zones because of

the use of low and varying colorific value and volatile matter of coals used in

India. With the marginally designed metallurgy of tubes for super critical boilers,

the variation of temperature will have more damaging effect. The boilers of super

critical designs will be a new experience with Indian coals of inconsistent colorific

value, with high ash low volatile matter may lead forced outages. It will take

some time for stabilizing this new version with Indian coals. The availability of

more than 90% is more important for an IPP than the marginal raise in cycle

efficiency.

There is a scarcity of trained man power for operating power plants based on

super-critical technology. Further, the delivery schedule for super-critical boilers

is longer.

Hence, in view of the above, sub critical parameters are considered for the

proposed boiler configuration.

5.2 Analysis of Alternative Sites for Location of Power Plant

Chapter-6 Environmental Monitoring Program

VIMTA Labs Limited, Hyderabad C6-1

6.0 ENVIRONMENTAL MONITORING PROGRAM

6.1 Introduction

Regular monitoring of environmental parameters is of immense importance to

assess the status of environment during project operation. With the knowledge of

baseline conditions, the monitoring programme will serve as an indicator for any

deterioration in environmental conditions due to operation of the project, to enable

taking up suitable mitigatory steps in time to safeguard the environment.

Monitoring is as important as that of control of pollution since the efficiency of

control measures can only be determined by monitoring.

Usually, as in the case of the study, an Impact Assessment study is carried over

short period of time and the data cannot bring out all variations induced by the

natural or human activities. Therefore, regular monitoring programme of the

environmental parameters is essential to take into account the changes in the

environmental quality.

6.2 Environmental Monitoring and Reporting Procedure

Monitoring shall confirm that commitments are being met. This may take the

form of direct measurement and recording of quantitative information, such as

amounts and concentrations of discharges, emissions and wastes, for

measurement against corporate or statutory standards, consent limits or targets.

It may also require measurement of ambient environmental quality in the vicinity

of a site using ecological/biological, physical and chemical indicators. Monitoring

may include socio-economic interaction, through local liaison activities or even

assessment of complaints.

6.2.1 Objectives of Monitoring

The objectives of environmental post-project monitoring are to:

• Verify effectiveness of planning decisions;

• Measure effectiveness of operational procedures;

• Confirm statutory and corporate compliance; and

• Identify unexpected changes.

6.3 Monitoring Schedule

Environmental monitoring schedules are prepared covering various phases of

project advancement, such as constructional phase and regular operational phase.

6.3.1 Monitoring Schedule during Constructional Phase

The proposed power project envisages setting up of boilers, turbines and cooling

towers, establishment of storage facilities for coal and ash. The construction

activities require clearing of vegetation, mobilisation of construction material and

equipment. The construction activities are expected to last for over three years.

monitored at regular intervals. Any abnormal rise shall be investigated to identify

the causes and appropriate action shall be initiated. Greenbelt shall be developed

for minimising dust propagation. The ambient air quality data should be transferred

and processed in a centralised computer facility equipped with required software.

Trend and statistical analysis should be done. These results are logged and

reviewed for correction on shift basis by HOD operation and reviewed periodically

during weekly and monthly reviews.

6.4.2 Water and Wastewater Quality Monitoring and Data Analysis

To ensure a strict control over the water consumption, flow meters shall be

installed for all major inlets. All leakages and excess shall be identified and

rectified. In addition, periodic water audits shall be conducted to explore further

possibilities for water conservation.

Methods prescribed in "Standard Methods for Examination of Water and

Wastewater" prepared and published jointly by American Public Health

documented and compared against the design values for any necessary corrective

action. This is checked on a daily basis and monthly reports are submitted to the

authorities concerned.

6.4.2.2 Monitoring of Groundwater

The monitoring of groundwater is the most important tool to test the efficiency of

ash pond performance. This is indispensable as it provides detection of the

presence of waste constituents in groundwater in case of leachate migration. In

this programme, water samples are taken at a predetermined interval and analysed

for specific pollutant expected to be in the leachate. For early detection of leachate

migration, if any, it is suggested to construct piezometers around the ash pond

site.

In addition to piezometers, monitoring wells should be installed to a depth of at

least 3-m below the maximum historic groundwater depth. Based on assumptions

and data about the characteristics of leachate to be generated, approximate

permeability of soils in the zone of aeration and direction and velocities of

groundwater flow, the maximum probable aerial extent of contaminant migration

can be estimated as a basis for establishing the position of monitoring wells.

A minimum of two ground monitoring wells should be typically installed at ash

disposal facility: one up-gradient well and one down-gradient well. It is suggested

to collect water samples and analyse. Records of analysis should be maintained.

All these observations are made on a daily & weekly basis and abnormalities are

controlled immediately.

6.4.3 Noise Levels

Noise levels in the work zone environment such as boiler house, cooling tower

area, DG house shall be monitored. The frequency shall be once in three months in

the work zone. Similarly, ambient noise levels near habitations shall also be

monitored once in three months. Audiometric tests should be conducted

periodically for the employees working close to the high noise sources. Periodic

checks and walk down checks are made on shift basis and any abnormality is

attended immediately.

6.5 Reporting Schedules of the Monitoring Data

It is proposed that voluntary reporting of environmental performance with

reference to the EMP should be undertaken.

The environmental monitoring cell shall co-ordinate all monitoring programmes at

site and data thus generated shall be regularly furnished to the State regulatory

agencies.

The frequency of reporting shall be on six monthly basis to the local state PCB

officials and to Regional office of MoEF. The Environmental Audit reports shall be

prepared for the entire year of operations and shall be regularly submitted to

regulatory authorities.

Risk Assessment and Disaster Management Plan

VIMTA Labs Limited, Hyderabad C7-1

7.0 RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN

7.1 Introduction

Hazard analysis involves the identification and quantification of the various

hazards (unsafe conditions) that exist in the proposed power plant operations. On

the other hand, risk analysis deals with the recognition and computation of risks,

the equipment in the plant and personnel are prone to, due to accidents resulting

from the hazards present in the plant.

Risk analysis follows an extensive hazard analysis. It involves the identification and

assessment of risks the neighboring populations are exposed to as a result of

hazards present. This requires a thorough knowledge of failure probability, credible

accident scenario, vulnerability of population etc. Much of this information is difficult

to get or generate. Consequently, the risk analysis is often confined to maximum

credible accident studies.

In the sections below, the identification of various hazards, probable risks in the

proposed power plant, maximum credible accident analysis, consequence analysis

are addressed which gives a broad identification of risks involved in the plant. The

Disaster Management Plan (DMP) has been presented.

7.2 Approach to the Study

Risk involves the occurrence or potential occurrence of some accidents consisting of

an event or sequence of events. The risk assessment study covers the following:

• Identification of potential hazard areas;

• Identification of representative failure cases;

• Visualization of the resulting scenarios in terms of fire (thermal radiation) and

explosion;

• Assess the overall damage potential of the identified hazardous events and the

impact zones from the accidental scenarios;

• Assess the overall suitability of the site from hazard minimization and disaster

mitigation point of view;

• Furnish specific recommendations on the minimization of the worst accident

possibilities; and

• Preparation of broad Disaster Management Plan (DMP), On-site and Off-site

Emergency Plan, which includes Occupational and Health Safety Plan.

• Check calls on random periodicity through dummy tests and responses.

7.3 Hazard Identification

Identification of hazards in the proposed power plant is of primary significance in the

analysis, quantification and cost effective control of accidents involving chemicals

and process. A classical definition of hazard states that hazard is in fact the

characteristic of system/plant/process that presents potential for an accident.

Hence, all the components of a system/plant/process need to be thoroughly

examined to assess their potential for initiating or propagating an unplanned

event/sequence of events, which can be termed as an accident. The following two

methods for hazard identification have been employed in the study:

• Identification of major hazardous units based on Manufacture, Storage and

Import of Hazardous Chemicals Rules, 1989 of Government of India (GOI Rules,

1989); and

• Identification of hazardous units and segments of plants and storage units based

on relative ranking technique, viz. Fire-Explosion and Toxicity Index (FE&TI).

7.3.1 Classification of Major Hazardous Units

Hazardous substances may be classified into three main classes; namely flammable

substances, unstable substances and toxic substances. The ratings for a large

number of chemicals based on flammability, reactivity and toxicity have been given

in NFPA Codes 49 and 345 M. The major hazardous materials to be stored,

transported, handled and utilized within the facility have been summarized in the

Table-7.1. The fuel storage details and properties are given in Table-7.2 and

Table-7.3 respectively.

1989 in conjunction with Environment Protection Act, 1986. This is referred here as

GOI Rules 1989. For the purpose of identifying major hazard installations the rules

employ certain criteria based on toxic, flammable and explosive properties of

chemicals.

A systematic analysis of the fuels/chemicals and their quantities of storage has been

carried out, to determine threshold quantities as notified by GOI Rules, 1989 and

the applicable rules are identified. Applicability of storage rules are summarized in

Table-7.4.

7.4 Hazard Assessment and Evaluation

7.4.1 Methodology

An assessment of the conceptual design is conducted for the purpose of identifying

and examining hazards related to feed stock materials, major process components,

utility and support systems, environmental factors, proposed operations, facilities,

and safeguards.

7.4.2 Preliminary Hazard Analysis (PHA)

A preliminary hazard analysis is carried out initially to identify the major hazards

associated with storages and the processes of the plant. This is followed by

consequence analysis to quantify these hazards. Finally, the vulnerable zones are

plotted for which risk reducing measures are deduced and implemented. Preliminary

hazard analysis for fuel storage area and whole plant is given in Table-7.5 and

Table-7.6.

7.4.3 Fire Explosion and Toxicity Index (FE&TI) Approach

Fire, Explosion and Toxicity Indexing (FE & TI) is a rapid ranking method for

identifying the degree of hazard. The application of FE & TI would help to make a

quick assessment of the nature and quantification of the hazard in these areas.

However, this does not provide precise information.

The degree of hazard potential is identified based on the numerical value of F&EI as

per the criteria given below:

Sr. No. F&EI Range Degree of Hazard

1 0-60 Light

2 61-96 Moderate

3 97-127 Intermediate

4 128-158 Heavy

5 159 and above Severe

By comparing the indices F&EI and TI, the unit in question is classified into one of

the following three categories established for the purpose (Table-7.7).

TABLE-7.7

FIRE EXPLOSION AND TOXICITY INDEX

Category Fire and Explosion Index (F&EI) Toxicity Index (TI)

I F&EI < 65 TI < 6

II 65 < or = F&EI < 95 6 < or = TI < 10

III F&EI > or = 95 TI > or = 10

Certain basic minimum preventive and protective measures are recommended for

the three hazard categories.

7.4.3.1 Results of FE and TI for Storage/Process Units

Based on the GOI Rules 1989, the hazardous fuels used by the proposed power

plant were identified. Fire and Explosion are the likely hazards, which may occur due

to the fuel storage. Hence, Fire and Explosion index has been calculated for in plant

storage. Estimates of FE&TI are given in Table-7.8.

Results of FE&TI analysis show that the storage of LDO and HFO falls into Light

category of fire and explosion index with a Nil toxicity index.

7.4.5 Maximum Credible Accident Analysis (MCAA)

Hazardous substances may be released as a result of failures or catastrophes,

causing possible damage to the surrounding area. This section deals with the

question of how the consequences of the release of such substances and the

damage to the surrounding area can be determined by means of models. Major

hazards posed by flammable storage can be identified taking recourse to MCA

analysis. MCA analysis encompasses certain techniques to identify the hazards and

calculate the consequent effects in terms of damage distances of heat radiation,

toxic releases, vapour cloud explosion etc. A host of probable or potential accidents

of the major units in the complex arising due to use, storage and handling of the

hazardous materials are examined to establish their credibility. Depending upon the

effective hazardous attributes and their impact on the event, the maximum effect

on the surrounding environment and the respective damage caused can be

assessed. The reason and purpose of consequence analysis are many folds like:

• Part of Risk Assessment;

• Plant Layout/Code Requirements;

• Protection of other plants;

• Protection of the public;

• Emergency Planning; and

• Design Criteria.

The results of consequence analysis are useful for getting information about all

known and unknown effects that are of importance when some failure scenario

occurs in the plant and also to get information as how to deal with the possible

catastrophic events. It also gives the workers in the plant and people living in the

vicinity of the area, an understanding of their personal situation.

• Selected Failure Cases

The purpose of this listing (refer Table 7.11) is to examine consequences of such

failure individually or in combination. It will be seen from the list that a vast range

of failure cases have been identified. The frequency of occurrence of failure also

varies widely.

7.4.5.1 Damage Criteria

The fuel storage and unloading at the storage facility may lead to fire and explosion

hazards. The damage criteria due to an accidental release of any hydrocarbon arise

from fire and explosion. The vapors of these fuels are not toxic and hence no effects

of toxicity are expected.

Tank fire would occur if the radiation intensity is high on the peripheral surface of

the tank leading to increase in internal tank pressure. Pool fire would occur when

fuels collected in the dyke due to leakage gets ignited.

• Fire Damage

A flammable liquid in a pool will burn with a large turbulent diffusion flame. This

releases heat based on the heat of combustion and the burning rate of the liquid. A

part of the heat is radiated while the rest is convected away by rising hot air and

combustion products. The radiations can heat the contents of a nearby storage or

process unit to above its ignition temperature and thus result in a spread of fire.

The radiations can also cause severe burns or fatalities of workers or fire fighters

located within a certain distance. Hence, it will be important to know beforehand the

damage potential of a flammable liquid pool likely to be created due to leakage or

catastrophic failure of a storage or process vessel. This will help to decide the

location of other storage/process vessels, decide the type of protective clothing the

workers/fire fighters, the duration of time for which they can be in the zone, the fire

extinguishing measures needed and the protection methods needed for the nearby

storage/process vessels. The damage effect on equipment and people due to

thermal radiation intensity is given in Table-7.9. Similarly, the effect of incident

radiation intensity and exposure time on lethality is given in Table-7.10.

7.4.6 Scenarios Considered for MCA Analysis

7.4.6.1 Fuel Storage

The details of storages in the proposed power plant are given Table-7.2 above. In

case of fuel released in the area catching fire, a steady state fire will occur. Failures

in pipeline may occur due to corrosion and mechanical defect. Failure of pipeline due

to external interference is not considered as this area is licensed area and all the

work within this area is closely supervised with trained personnel.

7.4.6.2 Modeling Scenarios

Based on the storage and consumption of various fuels the following failure

scenarios for the proposed power plant have been identified for MCA analysis and

the scenarios are discussed in Table-7.11. The fuel properties considered in

7.4.7 Pool Fire Models used for MCA Analysis

Heat Radiation program ‘RADN’ has been used to estimate the steady state

radiation effect from storage of fuel at different distances. The model is based on

the equations compiled from various literatures by Prof.J.P.Gupta, Department of

Chemical Engineering, IIT Kanpur.

7.4.8 Results and Discussion

The results of MCA analysis are tabulated indicating the distances for various

damages identified by the damage criteria, as explained earlier. Calculations are

done for radiation intensities levels of 37.5, 25, 12.5, 4.5 and 1.6-kW/m2, which are

presented in Table-7.13 for different scenarios. The distances computed for various

scenarios are from the center of the pool fire.

• Pool Fire Due to Failure of LDO Storage Tank (Figure-7.1)

The maximum capacity of storage of LDO in one tank will be 500 KL. The most

credible failure is the rupture of the largest pipe connecting to the storage tank.

As the worst case, it is assumed that the entire contents leak out into the dyke

forming a pool, which may catch fire on finding a source of ignition.

A perusal of the above table clearly indicates that 37.5 kW/m2 (100% lethality)

occurs within the radius of the pool which is computed at 12.1-m tank on pool

fire. This vulnerable zone will damage all fuel storage equipment falling within the

pool radius.

Similarly, the threshold limit for first degree burns is 1.6 kW/m2, this vulnerable

zone in which the thermal fluxes above the threshold limit for first degree is

restricted to 72.8-m in case tank on pool fire.

• Pool Fire Due to Failure of HFO Storage Tanks

The maximum capacity of storage of HFO in each tank will be 1000 KL. The most

credible failure is the rupture of the largest pipe connecting to the storage tank.

As the worst case, it is assumed that the entire contents leak out into the dyke

forming a pool, which may catch fire on finding a source of ignition.

A perusal of the above table clearly indicates that 37.5 kW/m2 (100% lethality)

occurs within the radius of the pool which is computed at 48.1-m tank on pool

fire. This vulnerable zone will damage all fuel storage equipment falling within the

pool radius. Similarly, the threshold limit for first degree burns is 1.6 kW/m2, this

vulnerable zone in which the thermal fluxes above the threshold limit for first degree

is restricted to 290.5-m in case tank on pool fire.

7.4.9 Conclusions on MCA analysis

• LDO Tank Farm

There will be one LDO storage tank each of 500 KL capacity will be provided in

the LDO tank farm. The results of MCA analysis indicate that the maximum

damage distances for 12.5-Kw/m2 thermal radiations extends upto 22.6-m in the

case of one full tank of 500-KL on fire during worst meteorological conditions. As

the fire resistant dyke walls will be created, no cumulative effect of one tank form

on fire to create fire on other tank farm is envisaged. The damage contours for

tank on fire of one LDO tank is shown in Figure-7.1.

• HFO Tank Farm

The results of MCA analysis indicate that the maximum damage distances for

12.5-Kw/m2 thermal radiations extends upto 90.0-m in the case of two full tanks

on fire during worst meteorological conditions. As the fire resistant dyke walls will

be created, no cumulative effect of one tank farm on fire to create fire on other

tank farm is envisaged. The damage contours for tank on fire of two HFO tanks is

shown in Figure-7.2.

7.4.10 Coal Handling Plant - Dust Explosion

Coal dust when dispersed in air and ignited would explode. Crusher house and

conveyor systems are most susceptible to this hazard. To be explosive, the dust

mixture should have:

• Particles dispersed in the air with minimum size (typical figure is 400

microns);

• Dust concentrations must be reasonably uniform; and

• Minimum explosive concentration for coal dust (33% volatiles) is 50 gm/m3.

Failure of dust extraction and suppression systems may lead to abnormal

conditions and may increase the concentration of coal dust to the explosive limits.

Sources of ignition present are incandescent bulbs with the glasses of bulkhead

fittings missing, electric equipment and cables, friction, spontaneous combustion

in accumulated dust.

Dust explosions may occur without any warnings with Maximum Explosion

Pressure upto 6.4 bar. Another dangerous characteristic of dust explosions is that

it sets off secondary explosions after the occurrence of the initial dust explosion.

Many a times the secondary explosions are more damaging than primary ones.

The dust explosions are powerful enough to destroy structures, kill or injure

people and set dangerous fires likely to damage a large portion of the Coal

Handling Plant including collapse of its steel structure which may cripple the

lifeline of the power plant.

7.5 Disaster Management Plan

7.5.1 Disasters

A disaster is a catastrophic situation in which suddenly, people are plunged into

helplessness and suffering and, as a result, need protection, clothing, shelter,

medical and social care and other necessities of life.

Disasters can be divided into two main groups. In the first, are disasters resulting

from natural phenomena like earthquakes, volcanic eruptions, storm surges,

cyclones, tropical storms, floods, avalanches, landslides, forest fires. The second

group includes disastrous events occasioned by man, or by man's impact upon the

environment. Examples are armed conflict, industrial accidents, radiation accidents,

factory fires, explosions and escape of toxic gases or chemical substances, river

pollution, mining or other structural collapses, air, sea, rail and road transport

accidents which can reach catastrophic dimensions in terms of human loss.

There can be no set criteria for assessing the gravity of a disaster in the abstract

since this depends to a large extent on the physical, economic and social

environment in which it occurs. What would be consider a major disaster in a

developing country, ill equipped to cope with the problems involved, may not mean

more than a temporary emergency elsewhere. However, all disasters bring in their

wake similar consequences that call for immediate action, whether at the local,

national or international level, for the rescue and relief of the victims. This includes

the search for the dead and injured, medical and social care, removal of the debris,

the provision of temporary shelter for the homeless, food, clothing and medical

supplies, and the rapid re-establishment of essential services.

7.5.2 Objectives of Disaster Management Plan [DMP]

The Disaster Management Plan is aimed to ensure safety of life, protection of

environment, protection of installation, restoration of production and salvage

operations in this same order of priorities. For effective implementation of the

Disaster Management Plan, it should be widely circulated and personnel trained

through rehearsals/drills.

Kharsia Tehsil of Raigarh District, Chhattisgarh State

Chapter-7

Risk Assessment and Disaster Management Plan

VIMTA Labs Limited, Hyderabad C7-15

The Disaster Management Plan should reflect the probable consequential severalties

of the undesired event due to deteriorating conditions or through 'Knock on' effects.

Further the management should be able to demonstrate that their assessment of

the consequences uses good supporting evidence and is based on currently

available and reliable information, incident data from internal and external sources

and if necessary the reports of out side agencies.

To tackle the consequences of a major emergency inside the plant or in the

immediate vicinity of the plant, a Disaster Management Plan has to be formulated.

The objective of the Industrial Disaster Management Plan is to make use of the

combined resources of the plant and the outside services to achieve the following:

• Effect the rescue and medical treatment of casualties;

• Safeguard other people;

• Minimize damage to property and the environment;

• Initially contain and ultimately bring the incident under control;

• Identify any dead;

• Provide for the needs of relatives;

• Provide authoritative information to the news media;

• Secure the safe rehabilitation of affected area; and

• Preserve relevant records and equipment for the subsequent inquiry into the

cause and circumstances of the Emergency.

• Rescue plans to attend any emergency to be kept ready with plant within

beyond plant and conduct regular drills on that.

In effect, it is to optimize operational efficiency to rescue, rehabilitate and render

medical help and to restore normalcy.

7.5.3 Emergencies

7.5.3.1 General Industrial Emergencies

The emergencies that could be envisaged in the plant and fuel storage are as

follows:

• A situation of fire at the hydrogen plant;

• A situation of fire at the tank farm of all storages;

• Slow isolated fires;

• Fast spreading fires;

• Structural failures;

• Contamination of food/water; and

• Sabotage/Social disorder.

7.5.3.2 Specific Emergencies Anticipated

• Fire and Explosion

Fire consequences can be disastrous, since they involve huge quantities of fuel

either stored or in dynamic inventory in pipelines or in nearby areas. Preliminary

hazard analysis has provided a basis for consequence estimation. Estimation can be

made by using various pool fire, tank fire consequence calculations. During the

study of Risk Assessment, the nature of damages is worked out and probability of

occurrence of such hazards is also drawn up.

7.5.4 Emergency Organization

It is recommended to setup an Emergency Organization. A senior executive who has

control over the affairs of the plant should lead the Emergency Organization. He

shall be designated as Site Controller. General Manager [O & M] can be designated

as the Incident Controller. In the case of stores, utilities, open areas, which are not

under the control of the Production Heads, Senior Executive responsible for

maintenance of utilities would be designated as Incident Controller. All the Incident

Controllers would be reporting to the Site Controller. The actions are well defined as

to what action on the spot to be taken with what devotion in option to avert any

emergency situation.

Each Incident Controller, for himself, organizes a team responsible for controlling

the incidence with the personnel under his control. Shift-in-charge would be the

reporting officer, who would bring the incidence to the notice of the Incidence

Controller and Site Controller. All major equipment will have periodic checks in each

shift and the action are to be follow with respect to each observatory during walk

down check specific to each equipment.

Apart from prevention, The Emergency Co-ordinators would be appointed. Each

Incident Controller, for him self, organizes a team responsible for controlling the

incidence with the personnel under his control. Shift-in-charge would be the

reporting officer, who would bring the incidence to the notice of the Incidence

Controller and Site Controller. All major equipment will have periodic checks in each

shift and the action are to be follow with respect to each observatory during walk

down check specific to each equipment.

In each shift, electrical supervisor, electrical fitters, pump house in-charge, and

other maintenance staff would be drafted for emergency operations. In the event of

power or communication system failure, some of staff members in the office/plant

offices would be drafted and their services would be utilized as messengers for quick

passing of communications. All these personnel would be declared as essential

personnel.

All major equipments will have periodic checks in each shift and the to follow up

action during walk down check specific to each equipment.

7.5.4.1 Emergency Communication

Whoever notices an emergency situation such as fire, growth of fire, leakage etc

should inform his immediate superior and Emergency Control Center. A place nearer

to the Gate House Complex shall be identified as Emergency Control Center. The

person on-duty in the Emergency Control Center should appraise the Site Controller.

Site Controller verifies the situation from the Incident Controller of that area or the

Shift In-charge and takes a decision about an impending On Site Emergency. This

would be communicated to all the Incident Controllers, Emergency Co-ordinators.

prepared and maintained.

7.6 Off-site Emergency Preparedness Plan

The task of preparing the Off-Site Emergency Plan lies with the District Collector;

however the off-site plan will be prepared with the help of the local district

authorities. The proposed plan will be based on the following guidelines.

7.6.1 Introduction

Off-site emergency plan would follow the on-site emergency plan. When the

consequences of an emergency situation go beyond the plant boundaries, it

becomes an off-site emergency. Off-site emergency is essentially the responsibility

of the public administration. However, the plant management will provide the public

administration with the technical information relating to the nature, quantum and

probable consequences on the neighboring population.

The off-site plan in detail will be based on those events, which are most likely to

occur, but other less likely events, which have severe consequence, will also be

considered. Incidents which have very severe consequences yet have a small

probability of occurrence would also be considered during the preparation of the

plan. However, the key feature of a good off-site emergency plan is flexibility in its

application to emergencies other than those specifically included in the formation of

the plan.

The roles of the various parties who will be involved in the implementation of an off-

site plan are described below. Depending on local arrangements, the responsibility

for the off-site plan would either rest with the plant management or with the local

authority. Either way, the plan would identify an emergency coordinating officer,

who would take the overall command of the off-site activities. As with the on-site

plan, an emergency control center would be setup within which the emergency

coordinating officer can operate.

An early decision will be required in many cases on the advice to be given to

people living "within range" of the accident - in particular whether they should be

evacuated or told to go indoors. In the latter case, the decision can regularly be

reviewed in the event of an escalation of the incident. Consideration of evacuation

may include the following factors:

• In the case of a major fire but without explosion risk (e.g. an oil storage tank),

only houses close to the fire are likely to need evacuation, although a severe

smoke hazard may require this to be reviewed periodically; and

• If a fire is escalating and in turn threatening a store of hazardous material, it

might be necessary to evacuate people nearby, but only if there is time; if

insufficient time exists, people should be advised to stay indoors and shield

themselves from the fire. This later case particularly applies if the installation at

risk could produce a fireball with very severe thermal radiation effects.

Although the plan will have sufficient flexibility built in to cover the consequences of

the range of accidents identified for the on-site plan, it will cover in some detail the

handling of the emergency to a particular distance from each major hazard works.

Power plant fire fighting system do have an extra fire fighting machine which will be

on the order of the shift in charge can proceed to any fire fighting work in a

neighborhood plant or any village or town etc.

7.6.2 Aspects Proposed to be considered in the Off-Site Emergency Plan

The main aspects, which should be included in the emergency plan are:

• Organization

Detail of command structure, warning systems, implementation procedures,

emergency control centers.

Names and appointments of incident controller, site main controller, their deputies

and other key personnel.

• Communications

Identification of personnel involved, communication center, call signs, network, list

of telephone numbers.

• Specialized Knowledge

Details of specialist bodies, firms and people upon whom it may be necessary to call

e.g. those with specialized fuel knowledge, laboratories.

• Voluntary Organizations

Details of organizers, telephone numbers, resources etc

Chapter-7

Risk Assessment and Disaster Management Plan

VIMTA Labs Limited, Hyderabad C7-26

• Fuel Information

Details of the hazardous substances stored and a summary of the risk associated

with them.

• Meteorological Information

Arrangements for obtaining details of weather forecasts and weather conditions

prevailing at that time

• Humanitarian Arrangements

Transport, evacuation centers, emergency feeding, treatment of injured, first aid,

ambulances and temporary mortuaries.

• Public Information

Arrangements for (a) Dealing with the media press office; (b) Informing relatives,

etc

• Assessment of Emergency Plan

Arrangements for:

(a) Collecting information on the causes of the emergency; and

(b) Reviewing the efficiency and effectiveness of all aspects of the emergency plan.

7.6.3 Role of the Emergency Co-ordinating Officer

The various emergency services would be co-ordinated by an Emergency

Coordinating Officer (ECO), who will be designated by the district collector. The ECO

would liaison closely with the site main controller. Again depending on local

arrangements, for very severe incidents with major or prolonged off-site

consequences, the external control would be passed to a senior local authority

administrator or even an administrator appointed by the central or state

government. The ECO will be equipped with address and phone numbers of

important agencies.

7.6.4 Role of the Local Authority

The duty to prepare the off-site plan lies with the local authorities. The emergency

planning officer (EPO) appointed should carry out his duty in preparing for a whole

range of different emergencies within the local authority area. The EPO should

liaison with the plant, to obtain the information to provide the basis for the plan.

This liaison should ensure that the plan is continually kept upto date.

It will be the responsibility of the EPO to ensure that all those organizations which

will be involved off site in handling the emergency, know of their role and are able

to accept it by having for example, sufficient staff and appropriate equipment to

cover their particular responsibilities. Rehearsals for off-site plans should be

organized by the EPO.

VIMTA Labs Limited, Hyderabad C7-27

7.6.5 Role of Police

Formal duties of the police during an emergency include protecting life and property

and controlling traffic movements.

Their functions should include controlling bystanders, evacuating the public,

identifying the dead and dealing with casualties, and informing relatives of death or

injury.

7.6.6 Role of Fire Authorities

The control of a fire should be normally the responsibility of the senior fire brigade

officer who would take over the handling of the fire from the site incident controller

on arrival at the site. The senior fire brigade officer should also have a similar

responsibility for other events, such as explosions. Fire authorities in the region

should be apprised about the location of all stores of flammable materials, water

and foam supply points, and fire-fighting equipment. They should be involved in on-

site emergency rehearsals both as participants and, on occasion, as observers of

exercises involving only site personnel.

7.6.7 Role of Health Authorities

Health authorities, including doctors, surgeons, hospitals, ambulances and so on,

should have a vital part to play following a major accident, and they should form an

integral part of the emergency plan.

For major fires, injuries should be the result of the effects of thermal radiation to a

varying degree, and the knowledge and experience to handle this in all but extreme

cases may be generally available in most hospitals.

Major off-site incidents are likely to require medical equipment and facilities

additional to those available locally, and a medical "mutual aid” scheme should exist

to enable the assistance of neighboring authorities to be obtained in the event of an

emergency.

7.6.8 Role of Government Safety Authority

This will be the factory inspectorate available in the region. Inspectors are likely to

satisfy themselves that the organization responsible for producing the off-site plan

has made adequate arrangements for handling emergencies of all types including

major emergencies. They may wish to see well-documented procedures and

evidence of exercise undertaken to test the plan.

In the event of an accident, local arrangements regarding the role of the factory

inspector will apply. These may vary from keeping a watching brief to a close

involvement in advising on operations.

The action plan suggested for control of the off-site emergencies is given in Table-

7.16.

ADMINISTRATIVE AND LEGISLATIVE BACKGROUND

AII-1

The legal framework is covered under several legislations. Brief details of the same are given below:

Legislative Framework

This section provides a brief summary of India's environmental legislation. Ministry of Environment and Forests (MoEF) is the nodal agency for drafting the new environmental legislations and giving the environmental clearance to the new projects. State Pollution Control Boards (SPCB) are responsible for implementing environmental legislation and issuing local Rules, Regulations and Notifications.

Regulatory Control of the Project

The proposed project is covered under the Environmental Impact Assessment (EIA) Notification, 1994 and amendments promulgated under Environment (Protection) Act (EPA), 1986. The key environmental legislations pertaining to the proposed operations include: • The Forest (Conservation) Act, 1980; • The Water (Prevention and Control of Pollution) Act, 1974; • The Air (Prevention and Control of Pollution) Act, 1981; • The Environment Protection Act, 1986, Rules there under (with amendments); • The Hazardous Wastes (Management & Handling) Rules 2000; • Environmental Impact Assessment Notification, 2006;and • Mines Legislation Pertaining to Environmental Protection. These key instruments and all subsequent and relevant amendments to them are discussed in further details as below.

• The Forest (Conservation) Act, 1980

Specified activities in forest areas are controlled under the Forest (Conservation) Act 1980 and clearances are required for such activities. The diversion of forestland for non-forestry purposes is not encouraged and clearances for such activities are difficult to obtain. Seismic surveys, are however, exempted from the provisions of the Forest Act providing these activities are restricted to clearing of undergrowth and lopping of tree branches and do not involve the felling of trees.

• The Water (Prevention and Control of Pollution) Act, 1974

This Act introduced the State Pollution Control Boards to grant Consent For Establishment (CFE) and Consent For Operation (CFO) to the industries. The investor intending to set up an industry is required to apply to the SPCB to obtain a CFE followed by CFO. While granting the consent, SPCB can stipulate conditions pertaining to the effluents arising from the process. The consent to operate is granted for a specific period (usually one year) after which conditions attached are reviewed by the SPCB before renewal.

ANNEXURE-II

ADMINISTRATIVE AND LEGISLATIVE BACKGROUND

AII-2

• The Air (Prevention and Control of Pollution) Act, 1981

This Act is very similar in scope to the Water Act, 1974. The Act stipulates the

establishment of State Boards for the Prevention and Control of Air Pollution. In States where a water pollution board had already been established under the earlier Water Act, the two boards were combined to form SPCBs. The establishment or operation of any industry cannot be undertaken without the prior consent of the SPCB. A decision on any application for consent must be made by the SPCB within four months of receipt of the application.

• Environment Protection (EP) Act and Rules, 1986

EP Act was enacted to provide for the protection and improvement of environment and for matters connected there with. A decision was taken by India to protect and improve the human environment at the United Nations Conference on Human Environment held at Stockholm in June 1972. It is considered necessary to prevent the hazards to human beings, other living creatures, plants and property.

This Act is an umbrella act and gave birth to many sub acts and rules. The EP Act

call for procedural requirements for:

o Obtaining Environmental Clearance; and o Submission of Environmental Statement.

The main Rules pertinent here are indicated below:

o The Hazardous Waste (Management and Handling) Rules, 1989 (with amendments upto 2000);

o Environmental Impact Assessment Notification; and o Public Hearing Notification.

• E.I.A Notification, 2006 and Subsequent Amendments

The principal Environmental Regulatory Agency in India is the Ministry of Environment and Forests (MoEF), New Delhi. MoEF formulates environmental policies and accords environmental clearance for the proposed, expansion/modernization of projects.

As per the Notification of the MoEF dated 14.09.2006 and its amendment, Environmental Clearance (EC) needs to be obtained from the MoEF for various identified industries. Any expansion or modernization of any activity shall not be undertaken in any part of India unless it is accorded environmental clearance by the central government in accordance with the procedures specified in this Notification. As per the procedure, anybody who desires to undertake any project in any part of India or expansion or modernization of any existing industry, a Detailed Project Report, which shall inter alia include an Environmental Impact Assessment (EIA) report, needs to be submitted.

In addition to the above requirements, the MoEF can notify certain areas as ecologically sensitive/fragile and all developmental projects which are to be located in these notified areas need to obtain EC. Areas so far notified include some coastal areas identified under the Coastal Regulation Zone Notification, forests, wildlife sanctuaries, national parks, wetlands and mangroves.

ADMINISTRATIVE AND LEGISLATIVE BACKGROUND

AII-3

• The Hazardous Wastes (Management & Handling) Rules 2000

These rules make the occupier and the occupier of a facility responsible for proper

collection, reception, treatment, storage and disposal of hazardous wastes listed in schedule-1, 2, and 3.

This rule also recommends to obtain and renew the authorization to collection,

reception, treatment, storage and disposal of hazardous wastes from state pollution control board (SPCB) by filing Form-1.

• Mines and Marine Legislation Pertaining to Environmental Protection

The environmental protection provisions covered under different legislation pertaining to petroleum up-stream (exploration, production and transport) are defined in the following subsections:

Mines & Minerals (Regulation & Development)

The Mines & Minerals (Regulation & Development) bill recognizes the need for providing greater stability of tenure to leaseholders. As such, for the first time, a minimum period of lease of 20 years, has been made mandatory. The maximum period for grant of lease has been increased to 30 years. There is a provision of renewal of a mining lease for a period of 20 years. Further renewals are possible with approval of the Central Government. These amendments would be of particular benefit to the captive coal mines in the Power Sector, where a number of projects have been approved, and also to other mines attached to mineral processing industries like steel, cement etc. where an assured supply of raw material is essential.

The period for which prospecting licence can be granted has been increased to three years and these licences can be renewed at the discretion of the State Governments so that the total period does not exceed five years

The bill has deleted 15 minerals hitherto listed in the First Schedule of the Act requiring prior approval of the Central Government before the State Government could grant a prospecting licence or a mining lease. The minerals so deleted are Apatite and phosphatic ores, Barytes, Dolomite, Gypsum, Kyanite, Magnesite, Molybdenum, Nickel, Platinum and other precious metals. Sillimanite, Silver, Sulpher and its ores, Tin, Tungsten and Vanadium Ore. With this deletion (excepting the atomic minerals and fuel minerals) there would only be 11 minerals left for which the State Government would require prior approvals of the Central Government. These are Asbestos, Bauxite, Chrome ore, Copper Ore, Gold, Iron ore, Lead, Limestone except where it is used in Kilns for the manufacture of lime as building material, Manganese ore, Precious stones and Zinc.

Prohibition of Mining Operation in Ecologically Fragile Areas

Government of India has identified a number of areas/eco-systems as ecologically fragile areas where mining is not allowed without prior permission from Ministry of Environment and Forests (MoEF), New Delhi, by specifying interalia the details of the area and the proposed process or operation duly supported by an EIA &

EMP and such other information as may be required by the Central Government. There are few ecologically sensitive areas where mining has been prohibited either by the court's order or by a MoEF Notification. • Directorate of Mines Safety

Under the Constitution of India, safety, welfare and health of workers employed in mines are the concern of the Central Government (Entry 55 - Union List; Article 246). The objective is regulated by the Mines Act, 1952 and the rules and regulations framed thereunder. These are administered by the Directorate general of Mines Safety (DGMS), under the union Ministry of Labour. Apart from administering the Mines Act and subordinate legislation thereunder, DGMS also administers a few other allied legislation, including the Indian Electricity Act

The pieces of legislation administered by DGMS are,

o The Mines Act, 1952 o Rules & Regulations framed under the Act, o Metalliferous Mines Regulations, 1961 o Mines Rules, 1955 o Mines Vocational Training Rules, 1966 o Mines Rescue Rules, 1985 o Mines Crèche Rules, 1966

Applicable Environmental Standards

The MoEF has the overall responsibility to set policy and standards for the protection of environment along with Central Pollution Control Board (CPCB).

Ambient Air Quality Standards

The existing standards for National Ambient Air Quality (NAAQ), as prescribed by CPCB vide Gazette Notification S.O.384 (E) dated 11th April, 1994, which are applicable for land-based applications for onshore areas. The prescribed standards are presented below in Table-1.

However 2% of the time, it may exceed but not on two consecutive days.

Noise Limits and Guidelines for Diesel Generators

• Noise from DG set shall be controlled by providing an acoustic enclosure or by treating the room acoustically, at the users end;

• The acoustic enclosure or acoustic treatment of the room shall be designed for minimum 25 dB (A) insertion loss or for meeting the ambient noise standards, whichever is on the higher side (if the actual ambient noise is on the higher side, it may not be possible to check the performance of the acoustic enclosure/acoustic treatment. Under such circumstances the performance may be checked for noise reduction upto actual ambient noise level, preferably, in the nighttime). The measurement for Insertion Loss may be done at different points at 0.5 m from the acoustic enclosure/room, and then averaged;

• These limits shall be regulated by the State Pollution Control Boards and the State Pollution Control Committees;

• The manufacturer shall offer to the user a standard acoustic enclosure of 25 dB (A) insertion loss and also a suitable exhaust muffler with insertion loss of 25 dB (A);

• The user shall make efforts to bring down the noise levels due to the DG set, outside his premises, within the ambient noise requirements by proper siting and control measures;

• Installation of a DG set must be strictly in compliance with the recommendations of the DG set manufacturer; and

• A proper routine and preventive maintenance procedure for the DG set should be set and followed in consultation with the DG set manufacturer which would help prevent noise levels of the DG set from deteriorating with use.

Ambient Noise Standards

Ambient standards with respect to noise have been notified by the Ministry of Environment and Forests vide gazette notification dated 26th December 1989 (amended in February, 2000). It is based on the ‘A’ weighted equivalent noise level (Leq). The ambient noise standards are presented in Table-2.

METHODOLOGY FOR SAMPLING AND ANALYSIS

AVI-1

1.0 Meteorology

The methodology adopted for monitoring surface observations is as per the

standard norms laid down by Bureau of Indian Standards (IS : 8829) and India

Meteorological Department (IMD).

1.1 Methodology of Data Generation

The Central Monitoring Station (CMS) equipped with continuous monitoring

equipment was installed at site at a height of about 10-m above ground level to

record wind speed, direction, relative humidity and temperature. The

meteorological monitoring station was located in such a way that it is free from

any obstructions and as per the guidelines specified under IS:8829. Cloud cover

was recorded by visual observation. Rainfall was monitored by rain gauge.

The continuous recording meteorological instrument of Dynalab, Pune (Model

No.WDL1002) has been used for recording the met data. The sensitivity of the

equipment is as given in Table-1.

TABLE-1

SENSITIVITY OF METEOROLOGY MONITORING STATION

Sr. No. Sensor Sensitivity

1 Wind speed Sensor ± 0.02 m/s

2 Wind direction Sensor ± 3 degrees

3 Temperature Sensor ± 0.2oC

Hourly maximum, minimum and average values of wind speed, direction and

temperature were recorded continuously with continuous monitoring equipment.

All the sensors were connected to filter and then logged on to datalogger. The

readings were recorded in a memory module, which was attached to datalogger.

The memory module was downloaded in computer through Dynalab software. The

storage capacity of memory module was 256 KB. Data was downloaded every

fortnight into the computer. The data was recorded continuously. The recovery of

data was about 98%. The rest of 2 % data gaps were filled by referring to IMD

data and daily weather reports in the local newspapers. However, Relative

Humidity and Rainfall were recorded manually.

1.2 Ambient Air Quality

1.2.1 Method of Analysis

The air samples were analyzed as per standard methods specified by Central

Pollution Control Board (CPCB), IS: 5184 and American Public Health Association

(APHA).

1.2.2 Instruments used for Sampling

Respirable Dust Samplers APM-451 instruments have been used for monitoring

Total Suspended Particulate Matter (TSPM), Respirable fraction (<10 microns) and

gaseous pollutants like SO2 and NOx. Charcoal filled glass tubes were deployed for

collection of carbon monoxide. Gas Chromatography techniques have been used for

the estimation of CO.

1.2.4 Sampling and Analytical Techniques

1] Total Suspended Particulate Matter TSPM, RPM, SO2 and NOx

SPM (>10 µ) and RPM (<10 µ) present in ambient air is drawn through the

cyclone. Coarse and non-respirable dust (>10µ) is separated from the air stream

by centrifugal forces acting on the solid particles. These separated particulates fall

through the cyclone's conical hopper and collect in the sampling cup placed at the

bottom of the cyclone. The fine dust (<10 microns) forming the respirable

fraction passes the cyclone and is retained by the filter paper. The TSPM is

estimated by summing up the SPM and RPM fractions collected separately as

above.

A tapping is provided on the suction side of the blower to provide suction for

sampling air through a set of impingers. Samples of gases are drawn at a flow

rate of 0.2 Liters Per Minute (LPM).

TSPM and RPM have been estimated by Gravimetric method (IS: 5182, Part IV).

Modified West and Gaeke method (IS-5182 Part-II, 1969) has been adopted for

estimation of SO2. Jacobs-Hochheiser method (IS-5182 Part-VI, 1975) has been

adopted for the estimation of NOx.

Calibration:

Calibration charts have been prepared for all gaseous pollutants. The calibration is

carried out whenever new absorbing solutions are prepared. All the Resirable Dust

Samplers are calibrated as per ASTM D-4096. The rotameter is calibrated using

soap bubble meter.

2] Carbon Monoxide

Charcoal filled glass tubes have been used for collecting the samples of Carbon

monoxide. The CO levels were analyzed through Gas Chromatography techniques.

The techniques used for ambient air quality monitoring and minimum detectable

level are given in Table-3.

Analysis of Collected Matter

Analysis was carried out at central laboratory. The pH of the water was measured

by pH meter. The weight of the total un-dissolved matter was obtained after

filtration. The weight of ash was obtained by combustion of the undissolved matter.

The weight of the total dried soluble matter obtained from the residue from a

measured portion of filtrate after evaporation to dryness.

1.3 Water Analysis

Samples for chemical analysis were collected in polyethylene carboys. Samples

collected for metal content were acidified with 1 ml HNO3. Samples for

bacteriological analysis were collected in sterilized glass bottles. Selected physico-

chemical and bacteriological parameters have been analyzed for projecting the

existing water quality status in the study area. Parameters like temperature,

Dissolved Oxygen (DO) and pH were analyzed at the time of sample collection.

The methodology for sample collection and preservation techniques was followed as

per the Standard Operating Procedures (SOP) mentioned in Table-4.

1.4 Soil Quality

At each location, soil samples were collected from three different depths viz. 30

cm, 60 cm and 90 cm below the surface and are homogenized. This is in line with

IS: 2720 & Methods of Soil Analysis, Part-1, 2nd edition, 1986 of (American

Society for Agronomy and Soil Science Society of America). The homogenized

samples were analyzed for physical and chemical characteristics. The soil samples

were collected and analyzed once in each season.

The samples have been analyzed as per the established scientific methods for

physico-chemical parameters. The heavy metals have been analyzed by using

Atomic Absorption Spectrophotometer and Inductive Coupled Plasma Analyzer.

The methodology adopted for each parameter is described in Table-6.

1.5 Noise Levels

1.5.1 Method of Monitoring

Noise level monitoring was carried out continuously for 24-hours with one hour

interval starting at 0030 hrs to 0030 hrs next day. The noise levels were monitored

on working days only and Saturdays, Sundays and public holidays were not

monitored. During each hour Leq were directly computed by the instrument based

on the sound pressure levels. Lday (Ld), Lnight (Ln) and Ldn values were computed

using corresponding hourly Leq of day and night respectively. Monitoring was

carried out at ‘A’ response and fast mode.

Parameters Measured During Monitoring

For noise levels measured over a given period of time interval, it is possible to

describe important features of noise using statistical quantities. This is calculated

using the percent of the time certain noise levels exceeds the time interval. The

notation for the statistical quantities of noise levels is described below:

• Hourly Leq values have been computed by integrating sound level meter.

• Lday: As per the CPCB guidelines the day time limit is between 07:00 hours to

22.00 hours as outlined in Ministry of Environment and Forest Notification S.O.

123 (E) dated 14/02/2000.

• Lnight: As per the CPCB guidelines the night time limit is between 22:00 hours to

07.00 hours as outlined in Ministry of Environment and Forest Notification S.O.

123 (E) dated 14/02/2000.

A rating developed by Environmental Protection Agency, (US-EPA) for specification

of community noise from all the sources is the Day-Night Sound Level, (Ldn).

Ldn: It is similar to a 24 hr equivalent sound level except that during night time

period (10 pm to 07 am) a 10 dB (A) weighting penalty is added to the

instantaneous sound level before computing the 24 hr average. This nighttime

penalty is added to account for the fact that noise during night when people usually

sleep is judged as more annoying than the same noise during the daytime.

The Ldn for a given location in a community may be calculated from the hourly Leq’s,

by the following equation.
