2) For change in existing fuel i.e. Coal instead of Natural Gas by installing 4 Coal fired Thermic

Fluid Heaters. EC amendment has been obtained for the same on 25th Sep 2014.

Now, JBF is planning for an amendment in EC for existing polyester chips manufacturing plant for

change in fuel for 9.9 MW captive power generation. The existing captive power plants will be standby

till suitable customers are available for sale after the proposed amendment. The company is proposing

that the net effective power generation will not be more than 9.9 MW after installation of coal fired 9.9

MW CPP.

Accordingly TOR was awarded from SEIAA, Gujarat vide letter no. SEIAA/GUJ/TOR/1(d)/154/2017,

dated 15th March 2017.

However, since partial construction activities for foundation of boiler & ESP were carried out, making it

a violation, they had applied under the violation window to SEIAA Gujarat as per the provision of

Notification S.O. 804(E) dated 14/03/2017 & its amendment S.O. 1030(E) dated 08/03/2018. In this

1.4.1 VISION DOCUMENT

“Vision of our company is to be a leading Polyester manufacturing company covering the entire

polyester value change in domestic & global market.”




Page | 1.3

1.5 PROJECT JUSTIFICATION

Present requirement of electrical energy is met through the 66 KV (10 MVA contract demand)

power utility connection from DGVCL.

The existing CPP is mostly Natural gas based turbine/generators. But currently it is not

operating due to very high cost of natural gas.

The current energy cost of power supplied by DGVCL is Rs. 7.61 per unit which has substantial

impact on operational cost and sustainability/survival of the company.

Power generation using natural gas is not economically viable, power supply from DGVCL

which is currently used is also becoming increasingly also. Hence, both conditions are not

viable under current domestic & export market scenario.

Considering the inconsistencies in assured NG supply & economic feasibility, JBF proposes a

fuel change from gas to coal based 9.9 MW CPP to make the manufacturing cost effective and

sustainable.

After proposed fuel change for captive generation by installing a 9.9 MW coal based steam

power plant, the electrical energy cost can be reduced upto Rs. 5.00 per unit considering

interest and depreciation and would be viable by continuous operation.

However, while proposing switch-over of fuels, JBF also intends to ensure that the proposed

installations will meet the permissible environmental norms by installing the required APCD like

ESP and lime dosing system.

Most of our competitors are either located in UT of DNH or Daman who have the privilege of

lower power cost (Rs 4.2/unit) or in Gujarat have their own coal base power plant. This makes

our operation difficult and put our sales under lot of pressure.

After the proposed amendment the company will not add any load on the state power grid, the

surrendered power to DGVCL can be beneficial for other power starved industries.

Also, most of the power in grid supply is based on coal so proposed change in fuel for captive

power generation is not anticipated any significant will not increase the overall coal load as the

quantity of grid power consumption will reduce.

The financial feasibility due to proposed change in fuel is provided in below given table 1.2.

R. Projected Cost/benefit Rs.950800/day

Difference in Cost = Total cost per day for Existing Power Plant - Total cost per day for Proposed Power Plant

= 1900800 - 950000= 950800 Rs./day

= 950800 x 330 days = 313764000 Rs./Annum

Current cost of power from DGVCL @ Rs.7.61/unit

After proposed amendment in fuel change, generation cost from coal will Rs.5.00

Differential cost of Rs.2.61 / unit x 190000 units x 330 days = Rs.16,36,47,000/- per annum

Therefore after fuel change from gas to coal and power purchase from DGVCL, the company shall have projected benefit of Rs.31.37 Cr. and Rs.16.36 Cr/Annum respectively

2.3 PROCESS TECHNOLOGY

2.3.1 CAPTIVE POWER PLANT

The process comprises, the generation of steam in the boiler and utilization of energy content of steam

in the steam turbine for doing the work on turbine blades to generate mechanical energy. The

mechanical energy is converted to electrical energy by the generator coupled to the steam turbine.

The steam is generated in a 45 Ton capacity AFBC boiler at a working pressure of 87 bar and 515 OC

temp.

The major system and components of boiler includes feed water system, coal feeding system with

combustion control, FD & ID fan, air pre-heater, ESP, chimney, ash collection &handling system.

The steam generated in the boiler is piped to the inlet of steam turbine and pass through the nozzles

where pressure energy of steam is converted to kinetic energy and directed towards a series of moving

and stationary blades to do the work on the turbine wheel and expands to a lower pressure and finally

to vacuum in the range of 0.186 (abs) bar. The outlet steam from the turbine is passed to air cooled

condenser, where it is condensed back to water in the range of 54OC and water is further re-utilized for

continuous feed supply to boiler and cycle is repeated.

Main plant equipment is supported by auxiliaries and systems such as fuel handling system, cooling

water circulation system/ cooling towers, softener plant, electrical equipment, ash disposal and handling

system, emission monitoring and control system etc. Tentative technical features and operating

parameters of the major equipment and systems are provided in subsequent sections.

Air Cooled Condenser

The exhaust steam from the steam turbine need to be condensed back in to water for recycling the

working media. In case of an air cooled condenser, the steam is passed through large panel of cooling

coil having fins. The steam is passed through the tubes and the atmospheric air is circulated over the

fins by means of a fan, so that the steam is cooled and condensed back to liquid by giving up its latent

heat of vaporizations to air. Primary purpose of incorporating the air cooled condenser to drastically

reduce the water consumption.

There are various advantages of air cooled condenser over water cooled condenser like it will eliminate

cooling tower usage and also use of water and apart from this it is easy to install and maintain. JBF will

install air cooled condensers.

The flue gas will pass through economizers, air pre heaters, and electrostatic precipitators and ID fan

to the chimney. The collection vessels will be provided at the bottom of the economizers, air pre heater

and the electrostatic precipitator hoppers. The dry ash collected in vessels will be conveyed to ash silos

by the application of compressed air/dense phase pneumatic conveyance system. The ash

accumulated in ash silos will be loaded in to tankers/covered trucks given to the manufacturer of Bricks

and ready mix concretes for promoting fly ash utilization, in compliance with the Fly Ash Rules. Ash

handling will be done by dense phase pneumatic conveying.

Dense Phase Conveying System

One major concern for operating a Coal based Thermal power plant is the proper management of Ash

generated after combustion of Coal, which is generally generated in the furnace itself and is trapped by

the ESP. If proper system is installed for handling this ash, major hurdle of ash management can be

overcome.

The Dense Phase Conveying System is the most reliable; efficient to minimize particularly the problems

for handling the wide and adequate range of dry bulk solids up to 200 TPH capacities at the exceeding

terminal distances - 1,200 meter. This system includes weighing, batching, blending, lump breaking,

storage, master control equipment etc. through Dense Phase Conveying System for bulk material

handling in the plant.

Dense Phase System is applicable to push the highly dense concentration of bulk solids effectively at

a low constant speed inside the conveying pipe lines. Any type of material (heavy, abrasive or, fragile,

crystalline or granular) can be conveyed without causing the degradation due to low velocity and less

wear to the system components. This type of conveying is reliable, flexible and maintenance free due

to less number of moving parts and it can be easily installed at places where space availability is very

less specially for installing conventional conveying systems.

The limited volume of air is utilized at the transporting vessel to move the material into the line at

maximum density while the balance air quantity is added along the conveying line through coupling unit

provided at starting on the pipeline to overcome the pipeline frictional losses; thus pumping material at

the highest obtainable efficiency. The Coupling Unit ensures a uniform gradient and helps to maintain

the material at maximum density. It also helps in maintaining the desired velocity and overcoming the

pipeline / bend's friction and helps to restart the flow of blocked material if any along the conveying line

regardless of length. This Coupling Unit also helps in minimizing the compressed air consumption and

pipe abrasion.

The plugging problem is prevented by improving the ratio of the material to air throughout the system

to convey the material at the highest obtainable efficiency and degree of reliability. The highly abrasive

materials can be conveniently conveyed at lowest possible velocities consuming nominal quantity of air

with the help of these systems. The highly flexible check valve provided with Coupling Unit fittings are

very responsive to any back feeding due to changes in conveying line pressure thereby allowing

throttling of the air supply pressure and volume automatically. The designing of the system depends

upon the properties of the material like convey ability, moisture contents, product degradation, bulk

densities etc.

2.3.2.4 POLLUTION CONTROL EQUIPMENT

Proposed Steam boiler of 45 TPH will be run on imported coal & emits flue gases which contain the

following constituents:

• Particulate matter (PM)

• Gaseous constituent’s viz. SO2 and NOx

To mitigate the effects of the air emissions are summarized as below:

A. Particulate Matter

Particulate matters generated from the plant are in the form of fly ash and bed ash. Bed ash is collected

in the hoppers located below the combustor and there is no emissions due to collection through

hoppers. In order to limit the concentration in the form of fine particulate matter as fly ash in the exit flue

gas to within the stipulated standards, Electrostatic Precipitator (ESP) is installed.

Electrostatic precipitator is provided with four fields (working – 3 + standby - 1) & typically six activities

viz. Ionization, Migration, Collection, Charge Dissipation, Particle Dislodging & Particle Removal take

place inside an electro static precipitator to remove the particulate matter from exhaust gas.

System for online monitoring of the pollutants shall be installed for monitoring the pollution levels.

The operation of ESP is linked with Boiler when ESP tripped boiler is also tripped. The technical details

of ESP are as below –

5. No. of fields Nos. 4

6. Maximum pressure drop across ESP mmWC 25 - 30

7. Maximum flue gas velocity across ESP m/sec <1

8. Design Pressure mmWC ±230

9. Minimum thickness of CRCA collecting plate

mm 1.2

10. Minimum electrode spacing mm 400

11. No. of ash collection Nos. 1 for each field (Source: JBF Industries Ltd - Sarigam)

B. Gaseous Emission

• Sulphur Dioxide (SO2): The fuel to be used in the boiler is imported coal that is low sulphur content

upto 0.5%. The emission of sulphur di-oxide from the flue gases is below 100 ppm. Lime dosing

will be done to reduce SO2 emission.

• Oxides of Nitrogen (NOx): The AFBC boiler furnaces operate in a temperature range between 800

to 900°C. At this temperature the formation of NOx by combination of atmospheric oxygen and

nitrogen is very low. Thus suitable operating parameters maintained in the AFBC furnaces limit the

NOx emissions.

through CETP.

Effluent Treatment Scheme

The existing effluent treatment plant consists of pre-treatment, primary, secondary and tertiary

treatment units.

The existing operation have adequate ETP infrastructure to meet all the consent standards. The ETP

has, Oil & grease traps, 2 collection/equalization & neutralization tanks, primary clarifier, 2 UASBs,

settling tank, 2 ASP based aeration tanks, secondary clarifier, over flow collection tank, tertiary clarifier,

tertiary clarifier over flow tank, Sand beds, Activated beds, UF & RO unit, treated effluent tank-Guard

pond, sludge drying beds, sludge decanters and ETP waste storage shed etc. The treated effluent with

due quality assurance is metered through magnetic flow meter and discharged into the GIDC drain.

The quality of the discharged effluent is assured through daily checks and analysis of critical

parameters. The company has installed continuous online monitoring system for flow, pH, COD, BOD

and TSS and is up liked to CPCB & GPCB. The discharged effluent is further processed through 15

MLD CETP Sarigam and finally discharged into the deep Arabian Sea through CETP/Marine diffuser

system.

The proposed amendment does not have any potential to generate any additional organic load. Hence,

the existing ETP is capable to take the load of the additional effluent. Acknowledgement copy for

obtaining CETP membership certificate is attached as Annexure – 8.

3. DESCRIPTION OF ENVIRONMENT 3.1 PRELUDE

Preparation of EIA report needs collection and analysis of baseline environmental data on which an

assessment can be done for prediction of impacts and suggest mitigation plan. It is therefore, necessary

to collect baseline environmental data for different environmental attributes that are likely to be affected

due to the proposed activity. Prior to implementation of any major developmental project or expansion

of existing project, it is very important to monitor/collect the prevailing environmental quality status or

the region, which is in the vicinity of project activity.

The environmental baseline data collected, helps in identifying the significant environmental issues and

assess the likely changes in the environmental quality after implementation of the proposed project.

The baseline environmental quality and the predicted impacts also help in determining the mitigation

measures that needs to be adopted to maintain the environmental quality of the region.

The baseline environmental monitoring study has been conducted for various environmental

components like air, water, noise, land use, biological & social environment, as delineated in the

approved ToRs granted by SEIAA, Gujarat.

The details of the study for establishment of baseline environmental status are described in subsequent

sections of this chapter.

3.2 METHODOLOGY

Primary survey at project site and surrounding area (10 km around project site) and the secondary data

taken from various sources has been used to derive the baseline environmental setting of the region.

The baseline monitoring for meteorology, ambient air quality, water quality, noise levels, soil quality,

hydrogeological aspects, ecological environment, land use/ land cover and socio-economic studies has

been carried out during the study period i.e. October-2018 to December-2018 by Precitech Laboratories

Pvt. Ltd. The methodology of data collection is specified in table 3.1 and satellite image of study area

3.3 PHYSIOGRAPHY, GEOLOGY AND SOIL

3.3.1 PHYSIOGRAPHY

The area is situated in the southernmost part of the Gujarat, which is adjacent to coastal area in western

side and hill area in eastern side. Interstate boundary of Dadra & Nagar Haveli and Gujarat is situated

in eastern side which is approximately 7-8 km. The area is located on the western side of the foot hills

of the Western Ghats and some geographical area is covered with some patches of reserve forests.

The intermittent river Darotha criss-cross the area and drain into Arabian Sea near Daman. Towards

the northeast side, it is surrounded by the ranges of Sahyadri Mountains (Western Ghats). The soil is

rich and fertile.

The topography is undulating and rolling. The territory has a hilly terrain, especially in the North and

West, which is surrounded by some small hills. The topographic contour indicates that the elevation of

area ranges between 20-200 m. Most of the area is having elevation between 20-40 m. The central part

of the study area is fairly plain with slightly elevated regions in N, WSW and ESE. The project site is at

an altitude of approximately 30 m above MSL.

(Source: Survey of India Toposheet)

3.3.2 GEOLOGY

The site lies at the southern side of the coast of Valsad area. The major formations seen at the vicinity

of the site are older tidal flats which belongs to rann clay formation and basalts which are extrusive

rocks of Deccan volcanic group of upper cretaceous to Eocene age. More than 80 % of the area is

composed of basalts. Holocene sediments are found along coastal parts of the district and include flood

plain deposits of rann clay formation, coastal dunes of akhaj formation and younger tidal flat (spit/bar

and shoal) deposits of Mahuva formation.

The area consists predominantly of basaltic flows intruded, profusely by the basic rocks. Some of the

flows carry giant phenocrysts of plagioclase, dacite flows are exposed near anklas. The basic dykes

are basaltic to dolertic in nature and trend in N-S to NNW-SSE, NW-SE, ENE-WSW and WNW-ESE

directions. Compositionally, these are similar to the lava type’s viz. normal tholeilite, olivine tholelite,

pictrite basalt and giant phenocryst basalt. Basalt sill and plug are present around Kaprada and

pangarbari respectively.

The bouger gravity anomaly varies between -70 to +30 m Gal. The basement depth is about 1500 m in

the western part which decreases towards east. The area lies in the moderate risk zone of seismic

zonation. Earthquake epicentres in the eastern parts have been recorded. Groundwater prospects are

good to excellent in alluvial plain, flood plain and vegetation anomaly geomorphologic domains.

3.3.3 GEOMORPHOLOGY

3.3.4 SOILS

3.3.4.1 SOIL OF THE AREA

Natural soils are the product of physical and chemical weathering of rocks. The physical properties are

formed during the course of formation and the subsequent existence is depending upon the topography,

hydro meteorological condition and human interference. Soil characteristics of a terrain are more

important aspects since they play a major role in ground water recharge and meet the basic needs of

all agricultural production.

Figure 3.4: Soil Map of the study area

(Source: NBSS)

Largely, the map indicates two different types of soil based on location as below:

1. Soils of Western Hills

2. Soils of Western Coast

This soils can be further classified based on the terrain, as below:

1. Soils of Interfluves / Soils of Western Coast

2. Soils of Alluvial Plains / Soils of Western Coast

3. Soils of Coastal Plains / Soils of Western Coast

4. Soils of North Sahyadri / Soils of Hilly Terrain

Soils of North Sahyadri can mostly be related to Clayey, mixed, iso-hyperthermic Lithic Ustropepts and

Fine, montmorillonitic, isohyperthermic Vertic Ustropepts. This soils are Shallow, well drained, clayey

soils on very gently sloping dissected hills with moderate erosion and moderate stoniness; associated

with moderately deep, well drained, fine soils with moderate erosion and slight stoniness.

Soils of Interfluves are Fine, montmorillonitic, isohyperthermic Typic Chromusterts associated with

Fine, montmorillonitic, isohyper thermic Vertic Ustropepts.This are Very deep, well drained, fine soils

on gently sloping basaltic interfluves with slight to moderateerosion; associated with very deep, well

drained, calcareous, fine soils on very gently sloping lands with slight erosion

Soils of Alluvial Plains are Fine, montmorillonitic (calcare-ous), isohyperthermic Typic Chromusterts.

This are Very deep, moderately well drained, calcareous fine soils on nearly level alluvial plain with

slight erosion; associated with very deep, moderately well drained, calcareous very fine soils on very

gently sloping lands with slight erosion.

Soils of Coastal Plains are Fine, mixed (calcareous), iso-hyperthermic Typic Halaquepts mixed with

Fine-loamy, mixed (calcareous), isohyperthermic Typic Halaquepts. This are Very deep, imperfectly

drained, calcareous fine soils on very gently sloping coastal plain with slight erosion and strong salinity;

associated with deep imperfectly drained, fine loamy soils with slight erosion and strong salinity.

About 60 per cent of the Umbergaon Taluka is covered by Ustropepts, of which Calcareous Typic

Ustropepts soil is predominant which is also seen in the highlands. This soil type is also present in Pardi

taluka. Typic Chromusterts with small amount of Vertic Ustropepts are the other soil types found in

Umbergaon taluka along with Dadra and Nagar Haveli. Talasari Taluka is largely covered by Lithic

Ustropepts mixed with little amount of Vertic Ustropepts.

3.3.4.2 METHODOLOGY

Physico-chemical parameters have been analysed to ascertain the baseline status of soil in the study

area. Four (4) nos. of soil samples were collected from selected locations during the study period and

analysed.

carbon in soil were “Medium” in range.

Total Nitrogen was found in the range of 209.55 kg/ha to 251.55 kg/ha which indicates that nitrogen

content of soil in the study area is “better” in range.

Total Phosphorous content was found in the range 36.3 kg/ha to 50.4 kg/ha which indicates that

phosphorus content of soil in the study area is “low” to “medium” in range.

Potassium content ranged was found in the range 150.15 kg/ha to 193.05kg/ha which indicates that

potash content of soil in the study area is “medium”.in range.

Based on the above analysis, it can be concluded that the soil in the study area is suitable for

agricultural purposes, however the soil needs to be enriched with some potassium & phosphorous

enriched fertilizers to upgrade its quality.

3.4 GEOHYDROLOGY AND WATER RESOURCES

3.4.1 GEOHYDROLOGY

Different types of drainage and stream order are very important for understanding the infiltration and

runoff of the water, especially in Perennial River like Damanganga observed near proposed area. These

different types of drainage pattern mainly depend on the local geography, geology, structures and

tectonics and also it depends on the slope of the area. The perennial river Damanganga is flowing in

the northern part of study area. The area is under the influence of the river Damanganga being the main

recharging source & controlling the drainage pattern. The study area lies neat the basin of this river.

Overall the drainage pattern of the area is dendritic. The Geohydrological investigation work carried out

in & around the study area reveals that the area is covered with thick layer of alluvial. These alluvial

deposits formed by river Damanganga are composed of argillaceous & arenaceous material in the form

of alternate bands of sand & clay. These aquifers are Silt in texture with grain size of fine to medium

grained. The site falls in a safe zone according to CGWB report 2013

3.4.2 GROUND WATER

Nature of aquifers of Deccan basalt is un-confined, while aquifers of quaternary alluvium are both

confined and un-confined. Ground water prospects are good to excellent in alluvial plain, flood plain

and vegetation anomaly geomorphologic domains. In the study area, the water extraction is done

through various types of sources like open well, hand pump and tube well. The depth of the open well

and tube well found between 60m and 90m.

3.4.2.3 OBSERVATIONS FROM GROUND WATER ANALYSIS

The following observation is based on the analysis of the samples:

pH of the samples has been found ranging from 7.51 to 7.82.

From the above results, it can be observed that in the majority of the study area, TDS level, total

hardness, and total alkalinity are above the desirable limits. However, the levels are well within the

permissible limits as per IS: 10500:2012 Drinking Water Standards. Maroli village sample

magnesium is slight higher than the desirable limits. Other parameters has been found within the

desirable limits.

Also the Total Coliform and Faecal Coliform in all the ground water samples have been found to

be absent.

3.4.3 SURFACE WATER

Darotha River passes through the study region before discharging in the Arabian Sea. It is a seasonal

river but swells during the monsoon period. After the construction of Madhuban Dam on Damanganga

River, flow of the river is controlled and that has helped in increasing the irrigation potential of the

Region. Surface water is also supplied for industrial and domestic purposes in the region from the

Damanganga Canal Distributary, in some villages of the study area open ponds are exists, which helps

to harvests rain water during monsoon season.

3.4.3.1 METHODOLOGY

8 surface water samples have been taken from river falling in the study area in carboys/ glass bottles

and preserved, as per the techniques explained by APHA in ‘Standard Methods for Examination of

Water & Wastewater’. The preserved samples were brought to the laboratory and analysed. The

samples have been analysed as per the procedures specified in ‘Standard Methods for the Examination

of Water and Wastewater’ published by American Public Health Association (APHA – 21st Edition) and

Bureau of Indian Standards. The methodology for analysis techniques was followed as per the

techniques mentioned in Annexure-11.

4. D Fish culture and wild life propagation

5. E Irrigation, industrial cooling or controlled waste disposal (Source: Classification of Inland Surface Water (IS 2296:1892))

3.4.3.3 OBSERVATIONS FROM SURFACE WATER ANALYSIS

The following observation is based on the analysis of the samples:

pH of the samples was found ranging from 7.6 to 8.16. DO was found to be ranging between 1.3 to

6.3 mg/l.

All parameters of Damanganga Canal (SW1), Darotha River (SW2), Karanjgam pond (SW3), Manda pond (SW4), Sarigam Pond (SW5), Damanganga river near NH. 8 (SW6), falls under class A, However, due to lower DO and higher BOD this samples falls under Class E as per classification of inland surface water standards.

The parameters like TDS, COD, BOD, Total hardness, chlorides, Nitrate and total-fecal coliforms of sample collected from Damanganga river near Zari causeway (SW7) were found high in range. This may be due to influence of tidal zone and industrial/ domestic wastewater.

In Valvada pond (SW8) sample COD, BOD, and coliforms value were found high in range it may be due to domestic activities like bathing washing etc.

3.5 CLIMATE AND METEOROLOGY

The year can be divided into four seasons. The winter season from December to February is followed

by the summer season from March to May. The south-west monsoon season is from June to

September. The post-monsoon season constitutes the months of October and November.

3.7 NOISE MONITORING

The most common and universally accepted scale of measuring noise levels is the ‘A’ weighted scale

which is measured as dB (A). The scale has been designed to weigh various components of noise

according to the response of a human ear.

3.7.1 METHODOLOGY

Noise level monitoring was carried out once at each location for 24 hours at hourly intervals, during the

study period. The day time limit is between 6 AM to 10 PM and night time limit is 10 PM to 6 AM. The

area with high noise potential in the existing plant have been monitored moreover, also nearby

residential area from the project site have been monitored.SCM100 Sound Level Meter from Envirotech

(type II) was used for noise level monitoring.

3.7.3 OBSERVATION FROM THE NOISE LEVEL RESULTS

From the above results, it can be observed that all the values were well within the prescribed noise

standards of CPCB in industrial, residential and silence zone. In commercial zone values are slightly

higher than the prescribe standards due to commercial activities and traffic movement.

3.8 LANDUSE/LAND COVER

The land use/ land cover study gives a detailed idea to understand how the land use for proposed

activity will affect the change in land use pattern, status of vegetation & land cover. The land use study

helps in identifying the sensitive receptors in the study region and the impact of air pollution on them.

3.8.1 METHODOLOGY

The land use/ land cover status has been studied for 10 km radial area around the project site boundary.

The land use/land cover has been presented in the form of a map prepared by using satellite image.

The satellite image & land use/ land cover details have been presented in the Figure 3.1 & Figure 3.13

respectively. The area calculations have been carried out using GIS software after geo-referencing the

interpreted data and the results tabulated in Table 3.15.

River Damanganga flows around 7.5 km and River Darotha flows around 3.6 km in the northeast

direction of the site. There are few ponds/lakes present within 10 km radius of the industry however the

water resources of district will not be affected with the expansion of the industry as the area fall under

the notified GIDC area. But in the coming years due to declining trend in the forest area with the variation

of monsoonal rainfall and ground water table the cultivable land area may tend to decline because of

the urbanization, encroachment and development of the buildings and roads in the surrounding lands.

The cultivable or agricultural land at present is 45 % while the fallow land is around 17.6 % both together

covering more than 60 % of the total area under study. The uncultivated/fallow lands are the lands,

which is left free without cultivation currently for various reasons such as replenishment of nutrient,

water scarcity, etc. Alongside other major industries there is also the presence of Salt work activities at

the coastal belts of the district which covers around 0.17% of the total study area. Built-up area covers

around 7.5% of total study area out of which industrial area is around 4.5 % and rest is other settlements.

There is presence of part of sea, river, waterbodies, canals and flood plains which occupies remaining

part of the study area.

3.9 ECOLOGY AND BIODIVERSITY

The term biodiversity is used to refer to life in all its forms and the natural processes that support and

connect all life forms. Biodiversity is not easily defined because it is more than just the sum of its parts,

as all its elements, regardless of whether to understand their roles or know their status, are integral to

maintaining functioning, evolving, resilient ecosystems. Complex concepts such as biodiversity are

often easier to grasp if reduced to their component pieces. While this approach does not give a

complete picture of how these species interact and combine to create biodiversity, it helps us

understand different aspects of biodiversity.

Species are a complete, self-generating, unique ensemble of genetic variation, capable of interbreeding

and producing fertile offspring. They (and their subspecies and populations) are generally considered

to be the only self-replicating units of genetic diversity that can function independently.

Thus, Biodiversity is the foundation of a vast array of ecosystem services essential for human well-

being. Since the exhaustive study would certainly require of one year with one overlapping season.

However, this report attempts to comprise the possible macro-biodiversity and the present data

produced in the report consist of reconnaissance survey and the database of the areas available in the

literatures that have been compared and mentioned.

In addition to the area identified for industrial development, major area in the study region has mango

orchards. The central, northern and western parts of the region are suitable for agricultural activities.

The main staple crops are paddy, ragi, small millets and pulses. Sugarcane is also cultivated in recent

years. The biotic composition in the study region indicates richness in species diversity. The details of

the ecological layout of the study area are presented in following sections.

3.9.3 FLORAL DIVERSITY OF THE STUDY AREA

The zone of Umbergaon Taluka shows fairly rich in plant biodiversity having more of annual and

perennial herbaceous vegetation. The small hillocks existing in the perimeter of the proposed project

site are already degraded forest patches and mainly comprised of planted trees and shrubs. Among the

plant biodiversity none of the species belongs to IUCN red list as well as schedule species as per wildlife

list. Common flora of the region is given as Annexure-12 (a). The vulnerable species (Bombax ceiba

and Dalbergia latifolia) as per IUCN Red list 2016-2 are found in the region. In addition to these

important species of plantation area of the region, many other wild species of flora are observed in the

forest and open unused area of the region. These wild species are given as Annexure-12 (a).

3.9.4 FAUNA OF THE STUDY AREA

During observations, the sighting of wild animals was lesser in the entire study area. The assessment

of wild life fauna has been carried out on the basis of information collected from personal interviews

with local peoples as well as sighting of some animals. During field survey common garden lizard was

observed frequently in the study area and occasionally some snakes belonging to both poisonous and

non-poisonous category. Observations for birds were made during a walk through in the chosen line

transects for sighting the birds. Dominant birds in the study area are Common peafowl, Common Myna,

House sparrow, House crow, Black drongo, Small green Bee eater, Spotted dove, Rose ring parakeet,

Blue rock pigeon, House swift, common babbler and the other birds are Indian robin, Black ibis, Indian

roller, white wagtail, Pond heron, cattle egret. The list of all observed & reported fauna is given as

Annexure-12 (a). There are two Schedule-I species viz. Pavo cristatus- Common Peafowl (Least

Concern /Sch-I) and Varnus bengalensis- Common Indian monitor (Least Concern /Sch-I) as per Wild

Life Protection Act (WLPA) in the study area. The conservation plan of these species is given as

Annexure-12 (b).

3.9.5 AQUATIC ECOLOGY

For the purpose of the aquatic ecology study, qualitative survey of some water bodies for identification

of Phytoplankton, Zooplankton, Bacteria and Fishes have been carried out. The study was conducted

once in the study period (Post Monsoon 2018). Only qualitative assessment for identification of the

aquatic flora & fauna has been conducted. The study for determination of aquatic ecological layout of

the area was conducted for locations as given in Table 3.16 & Figure 3.14. The samples for plankton

study were conducted following the method suggested by NIO & APHA. The samples for phytoplankton

were collected using plankton net of 25-micron net size using measured bucket. The samples of

zooplankton were collected using plankton net of 200-micron size. For each sample, 30 litres of

samples were passed/filtered through the plankton net to collect 100 ml concentrated sample. Studies

of fishes was conducted for identification of fishes in the fish catch done by local fishermen.

3.10.3 DEMOGRAPHY

The comparative demographic status of Gujarat and Maharashtra state, Valsad and Thane district and

UT Daman and Dadra Nagar Haveli shows that decadal population is highest in Daman UT (67.7%)

followed by UT DNH (55.5%) and project area (43.1%). In the remaining area, the decadal population

is less than project area. While the population density is the highest in the project area (2624 per sq.

km) comparative to states (Gujarat and Maharashtra) and other districts (Valsad and Thane). This

shows greater influx of migratory population in the industrial zone of Sarigam. The comparative status

of important demographic indicators at micro level with project area is indicated in table 3.17.

The project area witnessed highest population density (2624 population per sq. km) compared to other

States and districts and UT in the study area. This suggest project area being industrial area shows

more influx of population for livelihood. Talasari taluka of Thane District in Maharashtra has highest

sex ratio (1026 females per 1000 males) and the lowest is UT DNH (774 females per 1000 males).

Similar situation, also exist in rural and urban among states (Gujarat and Maharashtra); districts (Valsad

and Thane) and their engulfed taluka in the study area. The proportion of urban population is highest

in UT Daman (83.1%); followed by Pardi taluka (59.6%) of Valsad district and then project area 56.9%

of urban population. The literacy rate of the project area is less (72.9%) when compared with State of

Maharashtra (82.9%); Thane district (80.6%); UT Daman (88.7%) and Pardi Taluka (77.1%) but greater

than the state of Gujarat; Valsad district; DNH; Umbergaon and Talasari Taluka. The female literacy

rate is highest in Daman UT (80.9%) and the lowest in Talasari taluka (19.0%). The female literacy rate

in the project area is only 29.9%. Valsad district has highest work participation rate (78.6%) because

of the Asia’s largest industrial hub is located in the district.

3.10.4 DEMOGRAPHIC STATUS OF THE STUDY AREA:

The demographic profiles shows that a minimum population is 255 in Dev Pardi village; maximum

population 163360 in Vapi (M), and an average population is 7809 exist in the radial distance of 10 km

from the project site. While, the maximum population density is 41849 persons per sq. km in Vapi

Municipal and the minimum is 65 persons per sq. km in Pali village, the average population density is

1878 persons per sq. km. The highest total sex ratio in Bhathi Karmbeli village is 1070 females per




Page | 3.31

1000 male population, while the maximum is 823 per 1000 male population in Kachigham CT, and the

average sex ratio is 823 per 1000 male population. While the sex ratio of 0-6 populations has different

situation. The maximum sex ratio for 0-6 populations is 1129 females per 1000 males in Nagawas

village and the minimum 676 females per thousand male in village Jampore, while the average sex

ratio is 891 females per thousand male populations in the project area. The project area being the tribal

area, the proportion of Scheduled Caste is less compared to Scheduled Tribes population. The

maximum proportion ST population is found in Nandigam village (96.8%) while the minimum is 1.3% in

Sarigham (INA). The average ST population is 33.3%. The total literate population is maximum in Vapi

(INA) (84.0%), while the minimum is in Tumb villages with only 48.2% literacy. The average of total

literate population among villages within the 10 km of the project site is 72.9%. Similarly the female

literacy rate is highest in Vapi (INA) village (38.4%) and the lowest is 16% in Kachigham CT. However

the average female literacy rates is 29.9%, in the villages existing in the radial distance of 10 km from

the project site.

3.10.5 TRADE AND COMMERCE

Since the 65% of the project area (Sarigam) is covered with Umbergaon taluka the current description

is restricted to this region. However the cumulative effect of nearby Industrial area of VAPI; Union

Territory Daman and DNH – Silvassa to the Sarigam industrial area is witnessed. Trade and Commerce

includes wholesale and retail trade of all kinds and other commercial activities like financial, insurance,

real estate and business services. Chemicals, plastic, agro and food processing, paper and sugar

industries have developed well in the district. Chemical units at Vapi, Sarigam and chemical complex

at Atul. The Chikoo and mango are two important fruits of the district being exported. The important

commodities exported out of district from various towns are mentioned. There are nearly 86 branches

of banks in urban areas.

3.10.6 WORK PARTICIPATION

The percentage of main worker in project area is the highest (99.7%) in Jampore village and lowest is

in village Kanadi (46.6%), while the average percentage of main worker is 89% in the villages located

in the 10 km radial distance from the project site. The work participation rate is maximum in the village

Kachigham CT (66.6%) and the minimum is in village Tumb (29%); while the average work participation

rate is 41.5% in the villages located in the radial distance of 10 km from the project site. The population

largely engaged in service sector (48%); followed by Petty Business (15%); Casual Labour (13%);

Agricultural Labour (13%) and Cultivators (11%). The detailed villages’ wise demographic and work

participation status is indicated in Annexure - 13.

3.10.7 EDUCATION STATUS

The education status was explored in 10% of the sample villages which was discussed with Panchayat

members or school teacher for adult working population only. Table shown in table 3.18 are mere

approximate to give the rough idea of possible employment opportunity among the industries located

in the project areas. It is to be noted that the Skill gaps in the industries for persons having skilled

degree jobs are largely fulfill by the urban areas while the persons with unskilled jobs are largely taken

up from surrounding villages during construction and operation stage of the industries.

3.10.8 ECONOMIC STATUS

As per 2011 Census, among the registered establishments in the year of 2010-11 the four most

important establishments are related to manufacture of (1) Basic Metal Industries (2) Service activities

(3) Chemical & chemical Products (4) Textiles. Summary of the industrial analysis shows that in the

year 2010-11, the four most important establishments are related to manufacture of (1) Basic Metal

Industries (2) Service activities (3) Chemical & chemical Products (4) Textiles. It can be observed that

number of establishment and average number of persons working per day has also decreased in 2010-

11 as compared to the year 2009-10 Since Sarigham has a industrial hub, there is large influx of

population due to industrialization specially in Srigham (CT) city area and adjoining Vapi taluka of

Valsad district. Restricting to project area confined to Umbergaon taluka, the participation rate of

Sarigham INA is 46.7% which is more than to the work participation rate of Valsad District (43.57%).

This happened, due to rapid growth of industrilization and as being Asia’s faster growing and biggest

industrial hub. The project area is comprised of rural areas from Daman; DNH and Vapi of Valsad

district covering major industrial zone. The M/s JBF Industry Lmited is located in the GIDC of Sarigham

in nearest town from the site. The industrial township of Sarigham with adjoing Vapi holds its place of

importance on the "industrial" map and it is the fastest growing industrial area in Asia in terms of

chemicals and paper industries units.

3.10.9 QUALITY OF LIFE

It is largely based on the selective variables which directly implies way of living quality life. The villages

within the 10 km from the project sites shows that amenities like presence of Telephone/Mobile; Metal

Road; and Power supply are present in 100%of the villages. However some amenities are largely

present in the villages viz; Anganwadi centers (96.7%); Govt. Primary School (96.7%); Public and

Private mode of Transportation (91.7%); total sanitation campaign (81.7%); presence of self-help group

(78.3%) and presence of water source (River and canal) 56.7%. Apart from this, improvement and

upgradation of the service is also required for presence of agriculture society is only among 33.3%

villages; Commercial banks in 30% villages; presence of Government PHC/SC in villages is only 23.3%

and the government technical training institutions (ITIs) is only among 3% of the village largely missing

for the skill development of the youths in generating employment in the project area.

3.10.10 OBSERVATIONS

The nearest habitation area from the project site is village Sarigam. During survey in village, none of

the villagers have reported that any part of village is disturbed due to the existing operations.

4. Anticipated Environmental Impacts & Mitigation

Measures 4.1 PRELUDE

The Environmental Impact Assessment task starts with identification, prediction and evaluation of

impacts on the environment due to the proposed project. These involve objective and subjective

assessment of the project components, environmental attributes and their interrelationships. The

main aim of conducting impact assessment is to establish sustainability of project by ensuring

efficient mitigation measures for identified & predicted impacts. The objective is to include these

mitigation measures in the design engineering phase of the proposed project in order to minimise or

eliminate the impacts on the environment.

The main procedural steps can be summarized as follows:

Identification

This involves identification of the major activities, the environmental attributes, the impacts of

the proposed activities on the environmental attributes and formulation of ‘cause & effect’

matrix.

Prediction

This involves prediction of the nature, magnitude and significance of the impacts.

Evaluation

This involves assessment and designation of the significance to the impacts, which helps

deriving decision on implementation of the mitigation measures for the anticipated impacts

due to the project.

Communication

This allows for the communication of activities under the proposed project, their impacts, nature,

significance, & magnitude of impacts and proposed/ suggested alleviating measures for all

probable/ possible negative impacts among:

a) The project proponent;

b) The regulatory agencies;

c) All stakeholders and interest groups through public consultation, if applicable.

During the present study, the overall impacts of the project on various environmental attributes has

been identified, predicted and evaluated, in line with the MoEF&CC guidelines on EIA study and the

same has been presented in the successive discussions.

4.2 IDENTIFICATION OF IMPACTING ACTIVITIES

In the inception of impact assessment stage of present study, proposed activities & components

which can have probable impacts, have been identified from the project description. For ease of

study, the activities have been distributed in four main phases of the proposed project viz.

Construction & commissioning phase, Operation phase, Decommissioning phase and Natural

calamities. The activities are then categorised under the relevant phase. It is noted that proposed

plant site is in seismic zone-3 (moderate zone) & flood zone. Tsunami & cyclones are not observed in

study area. The details of the identified impacting activities & components of the construction &

commissioning and operation phases are tabulated in table 4.1.

3. Decommissioning phase Dismantling of structures of the project components,

cleaning of reactors, vessels & tanks before decommissioning, treatment of wastewater generated from cleaning of vessel.

4.3 IDENTIFICATION OF ENVIRONMENTAL ATTRIBUTES

Impact assessment is an activity designed to identify and predict the impacts on the environment

including human health & well-being, physical components and surrounding, taking into account the

requirements of legislative policies. Environmental changes, expected out of any physical

development, can result in adverse and/ or positive end results.

The activities, under execution of this project, are likely to affect the environment in varying degrees.

The relevant parts of the receiving environment have been subjectively singled out, as

ENVIRONMENTAL ATTRIBUTES, and the impact due to various activities on these attributes have

been studied. The typical set of environmental attributes and their relative importance, adopted for the

present study, has been presented at Table 4.2.

4.4 IDENTIFICATION OF IMPACTS

Identification of impacts involves possible anticipation of impact in terms of pollution or stress on

environmental attributes due to the identified activities. With reference to the identified impacting

activities of the construction & commissioning phase, operation phase, decommissiong phase and

Natural calamities for the proposed project, probable impacts negative or positive on environmental

attributes have been reported in the “Activity – Impact Matrix”.The outcome of the studies for

identification of various impacts have been formulated in form of an “Activity-Impact” Matrix as

presented in Table 4.4 for construction& commissioning phase and Table 4.5 for operation phase.

4.5 PREDICTION OF IMPACTS & MITIGATION MEASURES

The identified environmental impacts in Section 4.4 belong to different components of the

environment. All these impacts need to be aggregated to get a total score of the environmental impact

of the proposed project. Such aggregation may however involve considerable subjectivity. In the

following paragraphs, procedure of ‘Quantitative Evaluation Matrix’ is followed, as it is a simple and

reliable method. The criteria for evaluation of quantitative matrix are presented herewith:

(a) Negligible Impacts (Score 1): It signifies that the actions have some effect, but it will not cause

any quantifiable damage or benefit to the environmental parameters concerned.

(b) Moderate Impacts (Score 2): The activities and their environmental Impacts are judged to be

slightly significant or significant but for short term, the score is assigned to be 2.

(c) Significant Impacts (Score 3): If the activities and their environmental Impacts are judged to be

significant for long term but, reversible, the score is assigned to be 3.

(d) Highly Significant Impacts (Score 4): If the activities and their environmental Impacts are

judged to be significant, and irreversible, the score is assigned to be 4.

The (+) sign signifies positive impact and (-) sign signifies negative impact on the concerned

environmental attributes. The environmental impact evaluation matrix, for the proposed project,

without any mitigation measures and with the proposed mitigation measure for all the adverse

impacts, have been formulated in subsequent sections. Their respective cumulative impact matrices

are presented at Table 4.23 & Table 4.24.

An attempt has been made to predict the significance and magnitude of the identified impacts using

logical reasoning and available scientific knowledge. Use of mathematical tools/ models has also

been made wherever possible.

The attribute wise details of the task of prediction of the significance and magnitude of the identified

impacts are presented in subsequent sections.

4.5.1 AMBIENT ENVIRONMENT

Air quality & noise are attributes of ambient environment.

4.5.1.1 Ambient Air Environment

There will be no process emissions due to proposed amendment project as it is a project for

amendment in EC conditions for existing polyester chips manufacturing plant for change in fuel for 9.9

MW captive power generation.

There will be no process emission from the proposed project, hence impacts due to process

emission is not anticipated from proposed project.

Fugitive emissions are likely to occur mainly during transportation, handling and storage of the

Coal, limestone & fly ash.

Stacks connected to steam boilers would emit PM, SO2 and NOx emissions (single point

sources) due to burning of Coal as fuel.

To evaluate the probable impacts of emission on air quality, modelling was conducted using the

ISCST3 model for stack emissions from the plant and separately for emissions due to transportation

of raw materials, products & fuel. The air dispersion modelling is attaches as Annexure-15.

Chapter-4: Anticipated Impacts & Mitigation Measures

Page | 4.8


Vehicular emissions:

Impact on local air quality due to increased frequency of vehicular movement which may result in increase in PM, NOx & CO due to vehicular emission. The truck/ tanker trips during the operation phase will be around 12 truck trips per day.

Uncontrolled high emissions resulting in temporary increase of pollutants (PM, SO2, NOx & HCl) due to temporary breakdown of control equipment or emergency conditions.

Positive impact on ambient air quality due to greenbelt development.

Air quality is partly attributed to significant increase in airborne pollutants caused by damage of storage & related facilities during flood, earthquake & cyclone.

Dust generation due to earthworks and collapse during earthquake & cyclone.

4.5.2.1 OBSERVATIONS

The source of water is/ will be GIDC water supply dept.

In existing operations, the fresh water requirement is @1023 KLD which will increase to @1091 KLD after proposed amendment project.

In existing operations, total wastewater generation is @725 KLD bifurcated as @50 KLD as domestic waste water, @675 KLD as industrial waste water to ETP.

After proposed project, additional 32 KLD industrial wastewater will be generate, which will be treated in existing ETP followed by RO. The quantity of recycling effluent from RO will be increased@30 KLD. There will be no additional wastewater discharge into GIDC underground drainage. The total discharge into the GIDC underground drainage will be @544 KLD as per existing permitted quantity.

Existing ETP is adequate to cater the treatment for proposed industrial waste water generation quantity.




Table 4.10: Identification of Impacts & Mitigation Measures for Water Environment

Impact Mitigation


No impact on groundwater as groundwater will not be extracted.

Impact on fresh water resource due to water consumption for curing of foundations, construction work & domestic purposes etc. However, looking to the moderate construction work for the project and GIDC water supply department as a source of water supply during construction work, impact on water quantity will be negligible.

The impact in terms of water quality due to disposal of domestic wastewater without any treatment through increase in level of BOD, SS & COD in receiving water resources.

Surface water runoff from site which may carry cement, sand etc. required for construction will cause increase in turbidity level of receiving water resource by contaminating the GIDC storm water line.

Soil contamination due to spillages of oil/chemicals, vehicle washing areas etc. can cause contamination of groundwater as secondary impact.

Optimal utilisation of water for construction & commissioning phase to be ensured.

The construction work will be undertaken on site adjacent to existing operating site itself and hence existing sanitation facilities will be utilized for the disposal of domestic wastewater.

Provision of proper bunds or concrete flooring at storage areas, and vehicle washing areas to be ensured to avoid surface and groundwater pollution by runoff/ spillage.

Operation Phase

There will be no impact on Hydrology and quantity of water resources due to proposed project. The positive impacts on water during the operation phase due to increase in recycling quantity.

The surface runoff may be contaminated with coal dust from the storage areas.

Contamination of CETP if untreated effluent/ poorly treated water will be sent to it. If untreated/ poorly treated effluent will be discharged from CETP in receiving water body can contaminate receiving water body which can affect aquatic ecology also.

Proponent should follow practice of optimal utilisation of water during operation phase by providing fixed water distribution channel throughout the plant area with proper metering facilities.

The proponent has provided closed storage area for coal & silo for ash storage hence issue of impacts due to coal dust/ fly ash is not anticipated. The storage area is provided with impervious bottom and leachate collection line which will be connected with ETP.

The industrial effluent should be treated in the existing ETP consisting primary, secondary & tertiary treatment & then sent to CETP for further treatment & disposal.

Regular maintenance, monitoring & functioning of ETP should be ensured.

Discharge of treated effluent should be done after confirming




Impact Mitigation

Contamination of GIDC storm water line, if the untreated effluents finds its way into storm water drains.

Accumulation of wastewater on land may occur due to sudden spillage/ leakage in case of breakdown of water treatment facility which will result contamination of ground water by seepage.

Impacts may occur due to excessive spillage/ leakage of wastewater from broken pipeline/ crack in tank during earthquake, which may contaminate ground water.

Contamination of surrounding water bodies (surface water) and associated aquatic biodiversity may occur, if the untreated effluent gets mixed with storm water drains due to flood.

Hurdle to ETP operation due to underground installed pumps during flood.

permissible norms.

Proper storm water drainage facilities should be provided to ensure that no contaminated stream from industrial activities will not mix with storm water.

Holding tank of adequate capacity shall be provided to store untreated/ treated water.

4.5.4 SOCIO-ECONOMIC ENVIRONMENT

The proposed project is to be within the existing site. Hence no resettlement and rehabilitation

(R&R) is required.

Since the Project is well connected with the state highway and there will be no requirement of

additional infrastructures, therefore neither project site nor any part of study area will be disturbed

during the entire life of the project.

Minor change in traffic pattern is envisaged due to transportation of coal for proposed project.

4.5.4.1 ADEQUACY OF EXISTING ROAD NETWORK

There will be an increase in number of vehicles for transportation of the existing road network due to

the proposed project.

The additional traffic anticipated due to the proposed expansion is given in Table 4.17.

LMV = Light motor vehicles, HMV = Heavy motor vehicles, PCU = Passenger Car Unit (Source: Road and Building sub-division,Vapi)

After the proposed expansion, the total PCUs on Bhilad Sarigam fansa road will be 17584 per

day.

Hence, the average PCU on the approach road after the proposed expansion will be 733 per

hour.

As per IRC, the carrying capacity of Bhilad Sarigam fansa road is 1200 PCUs per Hour.

Thus, the existing road-network is capable to carry the additional traffic due to the proposed

project.

Impact Mitigation Measures

Construction & Commissioning phase

Impact on human health due to deterioration in local ambient environment quality due to increase in PM, NOx, CO & noise from construction work, fabrication work, vehicular movement for transportation of equipment. PM may cause lung disease, asthma, CO may block oxygen uptake, Nitrogen dioxide may give respiratory tract irritation and noise may give headache, stress etc.

Unsafe practices during construction work & installation of machineries, equipment & utilities can lead to accidents/ injury to workers.

Beneficial impacts to economy & positive to economic environment as the proposed project will provide direct and indirect employment to the local population, which will have a positive impact. Approx. 50 workers will be benefited in terms of contractual employment due to the proposed project. This will marginally improve the quality of life of the people in the region.

Vehicular movement for the proposed project on access roads to JBF from SH can cause traffic congestion, if not properly managed.

Barricading should be provided to control transfer of dust outside premises. Also, water spraying should be undertaken during constructions.

All requisite PPEs should be provided for safe execution of work.

Covered construction vehicles, PUC certified vehicles should be ensured.

Periodic preventive maintenance of transportation vehicles should be undertaken.

All employees / workers should be properly trained / supervised for their scope of work.

All requisite PPEs should be provided for safe execution of work.

Medical facilities to be in place for emergency.

Preference for direct/contractual employment should be given to the locals based on their skills and aptitude.

Local contractors should be hired.

SH-185 will be the main roadway for transportation of construction equipment and material. The incremental traffic is not likely to cause any congestion on the SH, as SH-185 has sufficient capacity to accommodate additional movement of vehicles. However, an effective traffic management plan should be developed to avoid congestion on the nearby/local/internal roads from SH-185 to JBF.

Operational Phase

During operation phase, impacts on social environment may occur mainly due to pollution of environment, competing use of water resources, hazardous material handling & storage, hazards associated with proposed project, noise generation, traffic etc.

Failure of pollution control systems or an accident may impact the health and safety of workers or neighbouring population.

The site is in industrial estate and away from the locality. The water requirement should be met through the water supply network of GIDC.

Implementation of appropriate pollution abatement and control measures should be ensured.





The high noise generation of turbine may result in major impact on human health (occupational) in terms of impairment in hearing or hearing loss.

Change in traffic pattern considering the connectivity of site with adjacent National Highway 8 will be negligible hence no considerable impacts on traffic pattern of the area are envisaged.

The risk assessment study indicates that by and large, the risks are confined within the factory boundary walls in case of fire, explosion and spillage of chemicals.

As per RA report, the total damage and Fatality zone due to fire & explosion up to 38 meters in worst case scenario and first degree burn zone up to 62 meter.

Beneficial impact by the proposed project as the direct employment opportunities will increase which will help in uplifting the economic status of the region. The proposed project will provide direct and indirect employment to the local population, which will have a positive impact.

Approx. 20 workers will be benefited in terms of direct employment due to the proposed project during regular operation phase.

During regular operations indirect un skilled employment will also be generated as helpers for maintenance

Local population will be benefited by the proposed project, as the indirect employment/trade opportunities will increase which will help in uplifting the economic status of the region for the following: o Transport sector - vehicular movement at stretch to bring the raw

material and finished goods to all over India as well export at international level;

o Labour sector: Proposed employment generation from expansion project will create indirect employment opportunity on labour contract labour.

To control noise levels, necessary mitigation like acoustic enclosures, housing of noise generating machineries in closed area/ room, proper maintenance & lubrication has been proposed by the proponent. Besides, necessary PPEs should be provided to the employees to prevent any kind of impacts on human/occupation health due noise.

Post project monitoring should be carried at regular intervals along with the regular health check-up of factory workers.

Traffic management to be done properly.

All safety measures to be provided, and all required essential plans to be implemented for emission reduction from storage & handling, safety, disaster & emergency action as mentioned in RA Report for proposed expansion project.

Preference for direct/contractual employment should be given to the locals based on their skills and aptitude.

Social development program should be conducted as the part of CER.





Occupational health, employment & traffic movement will get affected due to collapse of structure, spillage of materials, and breakdown of pollution control measures due to earthquake, cyclone & flood.

Flood can give impacts on occupational health if accidentally spilled material will be mixed with storm water

Demolition waste should be disposed as per statutory requirements as early as possible. The proponent must participate regional Disaster Management Plan and industrial association.

Plant should be immediately stopped in case of flooding.

Decommission Phase

Risk to community health and occupational health due to dust and noise generation during dismantling.

The site should be barricaded during dismantling activities.

Provision of PPEs (ear plugs, ear muffs) to all employees/labour involved near areas where there should be generation of loud noise.

4.5.5 ECOLOGICAL ENVIRONMENT

The proposed installation will be accommodated in the existing land & additionally adjoining plots.

The land is designated for industrial purpose. Hence, issue of impacts on ecology due to siting of

proposed expansion project is not envisaged.

There is no ecologically important area within the buffer area of 10 km. except the considerable

cultivated land and water bodies.

No major considerable impacts on water & land environments are noticed by the proposed

expansion project. All impacts studied are found minor & acceptable range.

Impacts are anticipated mainly due to the coal to be used which can have hazardous impacts.




Table 4.21: Identification of Impacts & Mitigation Measures for Ecological Environment



Impacts of PM on local Terrestrial flora & fauna (terrestrial & aves) may occur due to dust generated during construction work.

Also, noise generated during construction phase may create discomfort & hearing problems to fauna (terrestrial & aves) dwelling in vicinity of the site.

Such impacts of dust & noise generation and transportation would occur only for short period and would be restricted within close vicinity of the project site which is situated in the industrial estate devoid of any ecologically important habitat.

No impacts on aquatic ecology are anticipated.

During commissioning phase, impacts due to pollutant release in environment would be considerably higher for a specific period of commissioning time which may affect the terrestrial flora fauna especially due to gaseous emissions from utility, process & fugitive emissions.

In initial stage of this phase, effluent with high pollutant load may find its way to the aquatic habitat if not managed properly. This may result in considerable impacts on aquatic ecology like increase in Acidity, pH shift to acidic, eutrophication, increase in BOD & COD, and decrease in DO. All this chemical change in aquatic habitat may result in unexpected change in ecological balance of the habitat as well as mortality of many aquatic organisms.

The construction site should be barricaded, and water sprinkling arrangement should be provided to restrict & control the dust emissions.

Silencer to be provided to construction equipment.

To control noise level provision of necessary mitigation like acoustic enclosures, housing of noise generating machineries in closed area/room, proper maintenance & lubrication shall be ensured.

Efficient installation & operation of pollution control measures for air, water & hazardous waste should be provided before commissioning.

Operation phase

The project will have emission from boiler as well as coal & ash transportation/storage & handling. Hence, issue of impacts on ecology is anticipated mainly due to the increased particulate level in air due to the proposed project.

Such particulate may adversely affect the condition of nearby habitat – forest as well as other vegetative area due to the hindered photosynthetic activities as well as change in abiotic factors of the local ecology.

To prevent these impacts, efficient functioning of all necessary mitigation measures provided for control of emission of particulates from boiler as well as coal & ash handling operations should be ensured.





The heavy metal emissions from the coal combustion may have serious toxic effects on receiving habitat, the fauna & flora of the receiving habitat including terrestrial flora & fauna, avi fauna and aquatic flora & fauna.

The uncontrolled PM being emitted may also result in adverse impacts on fauna of the local area in terms of respiratory problems, eye problems etc.

Contamination of surrounding water bodies and hence toxic effects on associated aquatic biodiversity may occur, if the Coal & ash particle may get washed off from storage area with storm water during rainy days. Similarly toxic effects are also likely to occur in the flora of the local area due to seepage of leachate from coal & ash storage.

The boiler operations & steam turbine should have very high noise generation (about 88 dB-A) which is too high to cause hearing impairment in animal exposed to it. Especially the high noise generation during the shoot blowing operation may have considerable impacts on fauna dwelling in vicinity. Hence, chances of getting hearing problem in fauna dwelling near the boiler & turbine area are too high if the exposure in repeated.

All impacts mentioned for other activities would occur at higher or maximum level causing threat to terrestrial, avian & aquatic ecology during the period of breakdown of control equipment which gives uncontrolled release of pollutants.

Beneficial impacts on terrestrial flora & fauna due to increase in plant species.

During the tenure of natural disaster, major & highly significant impacts are likely to occur in term of toxic effects of the stored hazardous chemicals which may escape from storage facility due to failure/rupture. The toxic effects may vary from chemical to chemical as per their hazardous properties as given in table 7.2 of Chapter-7.

The proponent has planned to provide closed storage area for coal & silo for ash storage hence issue of impacts due to mixing of coal & fly ash particles with storm water is not anticipated.

It is suggested to provide the effective noise control & reduction measure for turbine to bring down noise level outside of the turbine area.

Regular maintenance of pollution control measures shall be done to minimise breakdown of control equipment.

Immediately stop manufacturing process till control equipment will be inline.

Implementation of measures and emergency facilities as mentioned in DMP and Emergency action plan.

Proper arrangements to reduce/elimination of chances of failure of hazardous chemical storage for prevention of escape of chemicals during natural disaster.


The impacts of decommissioning phase would be mainly due to change in air quality, disposal of untreated wastewater and high noise generation. The impacts would be similar to those mentioned in various activities of

The site under decommissioning work shall be ensured with all necessary mitigation measures suggested for prevention of emission & water pollution.





construction & commissioning phase as well as impacts of hazard in storage area.

The toxic effects of air pollutant, wastewater and hazardous waste would be higher or maximum.

Noise reduction measures should be provided.

All tanks and storage area should be cleaned properly and wastewater generated from these activities shall be treated prior to disposal. All solid/ hazardous wastes and chemicals should be disposed of through mode which are permitted as per regulatory provisions.

Chapter-5: Analysis of Alternatives

Page | 5.1

5. Analysis of Alternatives 5.1 PURPOSE OF THE STUDY

The details with respect to alternatives for site selection & process for the proposed project has been

summarized & provided in subsequent sections given below.

5.2 SITE ALTERNATIVES

As the proposed project is project for amendment in EC for existing polyester chips manufacturing plant

for change in fuel for 9.9 MW captive power generation. Which is to be carried out within the existing

site as well as plot adjacent to existing site designated for industrial use. Hence, no site alternative is

considered.

5.3 PROCESS ALTERNATIVES

The proposed project is for amendment in EC for existing polyester chips manufacturing plant for

change in fuel for 9.9 MW captive power generation. The existing CPP is mostly Natural gas based

turbine/generators. But currently it is not operating due to very high cost of natural gas. Also, power

generation using natural gas is not economically viable, power supply from DGVCL which is currently

used is also becoming increasingly also. Hence, both conditions are not viable under current domestic

& export market scenario.

After proposed fuel change for captive generation by installing a 9.9 MW coal based steam power plant,

the electrical energy cost can be reduced upto Rs. 5.00 per unit considering interest and depreciation

and would be viable by continuous operation. However, while proposing switch-over of fuels, JBF also

intends to ensure that the proposed installations will meet the permissible norms by installing the

required APCD like ESP and lime dosing system.

After the proposed amendment the company will not add any load on the state power grid, the

surrendered power to DGVCL can be beneficial for other power starved industries. Also, most of the

power in grid supply is based on coal so proposed change in fuel for captive power generation will not

increase the overall coal load as the quantity of grid power consumption will reduce.

Some technology alternatives are as below -

1. Boiler Alternatives:

The thermal power plant requires a boiler and there are several boiler choices available including

pulverized fuel as well as fluidized beds (circulating as well as atmospheric. At a boiler size of 45 tonnes,

the best current option is the Atmospheric Fluidized Bed Combustion (AFBC) boiler. The advantages

of such a boiler are that it allows for changes in fuel S% (since it has the capacity of fluidized boilers to

use limestone for sulphur-di-oxide reduction). A pulverized fuel boiler simply cannot handle fuels with

varying sulphur content owing to the fact that it is not amenable to limestone dosing. A CFBC boiler

allows for limestone dosing and is slightly more efficient compared to AFBC boilers but is not commonly

available at the size required (it is usually available in larger sizes).

2. Cooling System Alternatives:

In normal circumstance cooling media would have been water circulated through cooling towers for

conversion of steam to condensate and its reuse in boiler; however, considering the availability of water

in the Region in general and the necessity of saving water as given in the awarded ToR issued to the

project, the project proponents have decided to use air cooled condensers instead of water cooled

system for the boiler. This saves substantial amounts of water.



Chapter-6: Environment Monitoring Plan

6. Environment Monitoring Plan

6.1 PRELUDE

Post-project environmental monitoring is an essential tool for ensuring effective implementation of

environmental management plan & mitigation measures. It is also very essential to keep updating the

environmental management system for effective conservation of environment along with ongoing

project activities/ operation. The environment monitoring plan also gives an early indication, highlighting

the need to strengthen the existing environmental management system to enable for improvement &

conservation of various environmental attributes. It provides the status on the quality of environment

and helps in providing guidance on which environmental attributes, the mitigation measures need to be

improved. Hence, monitoring of critical parameters of environmental quality is very essential during the

project operations to assess the changes in the environment.

The objectives of monitoring are delineated hereunder:

Monitoring & tracking the effectiveness of Environment Management Plan.

Assessment of the changes in environmental quality post project operations and plan additional

mitigation measures, if any.

This chapter discusses various components & aspects of environmental monitoring plan designed for

JBF.

EIA Notification 2006 and it subsequent amendments include the following:

Public Consultation.

Social Impact Assessment. Resettlement & Rehabilitation (R&R) Action Plans.

Risk assessment.

The requirements of the above for the current proposed project are discussed in the subsequent sub-

sections under respective heading.

7.2 PUBLIC CONSULTATION

Public consultation is applicable to the proposed project as per the TOR granted by SEIAA Gujarat.

Hence, Environment Public hearing will be conducted as per the schedule of state pollution control board

and necessary action to address the issues raised in Environment Public hearing will be initiated

immediately after public hearing.

The present report is the “Draft EIA Report” prepared for the Public Hearing procedures. Up on

completion of Public hearing as required, details of public hearing and necessary justification for query

cited in PH will be incorporated for preparation of Final EIA report.

The final EIA report thus prepared will be used for further proceeding for environmental clearance and

other necessary clearances/ certification / licenses.

7.3 RESETTLEMENT & REHABILITATION ACTION PLAN

As described in earlier chapters, the proposed project being an amendment in existing environment

clearance conditions for existing Polyester chips manufacturing plant for change in fuel for 9.9 MW

captive power generation. The proposed installation will be accommodated in the existing land & some

part of proposed installation will be done on additionally adjoining plots. The existing plots and additional

land are/will be taken on lease from the GIDC. Hence, there will not be any resettlement & rehabilitation

due to the proposed project. Therefore, R&R study is not applicable for the proposed project.

7.4 RISK ASSESSMENT & DISASTER MANAGEMENT PLAN

7.4.1 OBECTIVE

The main objectives of the Risk Assessment (RA) study is to determine damage due to major hazards

having damage potential to life & property and provide a scientific basis to assess safety level of the

facility.

The principle objective of this study is to identify major risks in the storage of hazardous fuels at site and

to evaluate on-site & off-site consequences of identified hazard scenarios. Suggestions are given for

effective mitigation of hazards for effective disaster management, suggesting preventive and protective

measures & change of practices to ensure safety.

Relevant information about the existing and proposed storage facilities, process safety and emergency

preparedness of the plant was collated:

1. Based on the existing and proposed storage facilities, certain hazards have been identified and their

consequences modelled mathematically, using HAMS-GPS software. HAMS-GPS, constitutes one

of the most comprehensive Windows based software package that conforms to the

relevant International Standards to study EHS management and advanced consequence modelling

and Quantitative Risk Analysis / Assessment - QRA Study Softwares .




Page | 7.2

2. The study indicates that possible hazards associated with the plant are confined to (a) FO/ HSD

tank farm area (b) Road tanker unloading area (c) Coal storage yard (d) Natural Gas Pipeline.

3. The consequences of hazards associated with any possible spills / leaks or catastrophic failure of

storage tank/ pipeline release scenarios would be taken care of within the existing emergency

facilities and the manpower deployed at the plant.

4. The possibility of occurrence of such hazards and their effects could be further reduced by

implementing the suggestions made in this report. Conclusion are based on the risk analysis study

and information regarding the layout plan and safety systems.

Interlocking on pressure/ flow is provided.

Permit to work system is in exists for Hot work.

C. Safety in Coal storage yard

Air circulating within a coal pile should be restricted as it contributes to heating; compacting helps seal air out.

Coal having high moisture content should be segregated and used as quickly as possible. Efforts should be made to keep stored coal from being exposed to moisture.

Dry coal shall be kept dry and should be not exposed to any rain during storage period. This concerns what is known as the heat-of-wetting;

Drying coal is an endothermic process [heat is absorbed] and lowers the temperature of the coal. Wetting (or gaining moisture) is an exothermic process and the liberated heat can accelerate the spontaneous heating of the coal.

Following the "first in, first out" rule of using stock reduces the chance for hot spots by helping preclude heat buildup for portions of stock which remain undisturbed for a long term. The design of coal storage bins is important in this regard.

A high ambient temperature aids the spontaneous heating process.

Use coal as quickly as practicable. The longer large coal piles should allowed to sit, the more time the spontaneous process has to work.

The shape and composition of open stockpiles can help prevent fires. Dumping coal into a big pile with a trestle or grab bucket can lead to problems. Rather, coal should be packed in horizontal layers, which are then leveled by scraping and compacted by rolling. This method helps distribute the coal evenly and thus avoids breakage and segregation of fine coal. Segregation of coal particles by size should be strenuously avoided, as it may allow more air to enter the pile and subsequent heating of finer sizes.

Properly inspect, test and maintain installed fire protection equipment.

Maintain an update pre-fire plan and encourage regular visits to coal facilities by the site or local emergency response force.

Premedical examination, periodical medical examination should be carried out and record needs to be maintained in form No-32 & 33

respiratory exposure by a worker.

TWA limit: 0.9 mg/m3 - measured according to American Conference of Governmental Industrial

Hygienists ( ACGIH) criteria.

Occupational effect to worker: pneumoconiosis due to long exposure of Coal dust.

Measurement of exposure level of Coal dust in work place:

As per Factories Act, it is mandatory to carry out work place monitoring in such areas where exposure

of Coal dust is possible and record should be maintained. If the exposure level found is above TWA

limit, company has to provide engineering controls to control exposure level at any time below TWA

limit.

Control measures to be adopted by company to control Coal dust exposure in work place.

Separate Coal storage yard is provided, sufficiently away from the manufacturing plants.

Coal receiving, handling and storage facility is designed in such a way that Coal dust exposure

level should remain below TWA limit at all times.

1. Coal dust Temporary discomfort to upper respiratory tract may occur due to in halation of high dust levels well above the 8 hour occupational exposure limit. Long term inhalation of coal dust may lead to pneumoconiosis.

Prevent exposure to high temperatures and flames. Prevent exposure to strong oxidizers. Store in a dry clean area. Avoid creating dust. Clean up all spills promptly. Wash exposed skin daily. Wash work clothes daily If necessary, refer to the “NIOSH Guide to the Selection and Use of Particulate Respirators Certified under 42 CFR 84” for selection and use of respirators with organic vapor cartridges certified by NIOSH.

1. Air circulating within a coal pile should be restricted as it contributes to heating compacting helps seal air out.

2. Coal having high moisture content should be segregated and used as quickly as possible. Efforts should be made to keep stored coal from being exposed to moisture.

3. Dry coal shall be kept dry and shall be not exposed to any rain during storage period. This concerns what is known as the heat-of-wetting

4. Drying coal is an endothermic process [heat is absorbed] and lowers the temperature of the coal. Wetting (or gaining moisture) is an exothermic process and the liberated heat can accelerate the spontaneous heating of the coal.

5. Following the "first in, first out" rule of using stock reduces the chance for hot spots by helping preclude heat buildup for portions of stock which remain undisturbed for a long term. The design of coal storage bins is important in this regard.

6. A high ambient temperature aids the spontaneous heating process.

7. Use coal as quickly as practicable. The longer large coal piles are allowed to sit, the more time the spontaneous process has to work.

8. The shape and composition of open stockpiles can help prevent fires. Dumping coal into a big pile with a trestle or grab bucket can lead to problems. Rather, coal should be packed in horizontal layers,

which are then leveled by scraping and compacted by rolling. This method helps distribute the coal evenly and thus avoids breakage and segregation of fine coal. Segregation of coal particles by size should be strenuously avoided, as it may allow more air to enter the pile and subsequent heating of finer sizes.

9. Properly inspect, test and maintain installed fire protection equipment.

10. Maintain an update pre-fire plan and encourage regular visits to coal facilities by the site or local emergency response force.

11. Premedical examination, periodical medical examination shall be carried out and record needs to be maintained in form No-32 & 33

12. Work place monitoring and health and hygiene surveillance to be conducted and regularly work place monitoring needs to be carried out and record to be maintained in Form No-37

7.4.7 HAZARD IDENTIFICATION & CONSEQUENCE ANALYSIS

The details of probable hazards and consequences analysis for the probable hazards associated with

the hazardous materials of the proposed project are described below.

7.4.7.1 HAZARD IDENTIFICATION

Risk assessment process rests on identification of specific hazards, hazardous areas and areas

vulnerable to effects of hazardous situations in facilities involved in processing and storage of

chemicals.

Hazards posed by particular installation or a particular activity can be broadly classified into fire/

explosion hazards and toxicity hazards. Whether a particular activity is fire/explosion hazardous or

toxicity hazardous, it primarily depends on the materials handled and their properties.




Page | 7.13

Main hazards are storage of petroleum products and storage of Coal. The primary concern has always

been fire prevention and control as these are the main hazard posed by the unit. This concern has

grown through the loss of life, property and materials experienced after major disasters, which have

occurred over the years.

7.4.7.3 IDENTIFICATION OF HAZARDOUS AREA

The following areas within the plant are considered as a high hazard areas:

HSD/ FO/ MEG storage tank area

Coal storage yard

NG skid & pipeline

It is observed that the Natural gas PRV station area and fuel bulk storage area pose fire/explosion

hazards as it has a substantial inventory, which may lead to major emergency.

7.4.7.4 MODES OF FAILURE

Analysis of the above leads to reduction of total list of incidents into three representatives sets viz.:

HSD/ FO/ MEG release due to catastrophic failure of storage vessel or road tanker.

Liquid release through a hole/crack developed at welded joints/flanges/nozzles/ valves etc.

Gas release due to catastrophic failure of gas pipe line.

Fire in Coal yard

7.4.7.5 DAMAGE CRITERIA FOR HEAT RADIATION

Damage effects vary with different scenarios. Calculations for various scenarios are made for the above

failure cases to quantify the resulting damages. The results are translated in term of injuries and

damages to exposed personnel, equipment, building etc.

Tank on fire /pool fire due to direct ignition source on tank or road tanker or catastrophic failure can

result in heat radiation causing burns to people depending on thermal load and period of exposure.

All such damages have to be specified criteria for each such resultant effect, to relate the quantifier

damages in this manner, damage criteria are used for Heat Radiation.

6 Burns (escape routes)

4.5 Not lethal, 1st degree burns

3 1st degree burns possible (personnel only in emergency allowed)

2 No discomfort even after long exposure

1.5 No discomfort even after long exposure

7.4.7.6 EFFECTS OF RELEASE OF HAZARDOUS SUBSTANCE

Hazardous substances may be released as a result of failures/ catastrophes, causing possible damage

to the surrounding area. In the following discussion, an account is taken of various effects of release of

hazardous substances and the parameters to be determined for quantification of such damages.

In case of release of hazardous substances, the damages will depend largely on source strength. The

strength of the source means the volume of the substance released. The release may be instantaneous

or semi-continuous. In case of instantaneous release, the strength of the source is given in kg and in

semi-continuous release the strength of the source depends on the outflow time (kg/s).

In case of fire, it is first necessary to determine the state of a substance in a vessel to determine souce

strength. The physical properties viz., pressure and temperature of the substance will help to determine

the state of substance. The substance may be gas, gas condensed to liquid, and liquid in equilibrium

with its vapour or solids.

Instantaneous release will occur, for example, if a storage tank fails. Depending on the storage

conditions, the following situations may occur.

The source strength is equal to the contents of the capacity of the storage system.

Pool Fire:

In the event of the instantaneous release of a liquid, a pool of liquid will be formed. The evaporation

can be calculated on the basis of this pool.

The heat load on object outside a burning pool of liquid can be calculated with the heat radiation model.

This model uses average radiation intensity, which is dependent on the liquid. Account is also taken of

the diameter-to-height ratio of the fire, which depends on the burning liquid. In addition, the heat load

is also influenced by the following factors:

Distance from the fire

The relative humidity of the air (water vapour has a relatively high heat-absorbing

capacity)

The orientation i.e. horizontal/vertical of the objective irradiated with respect to the fire.

Jet Fire:

The escaping jet of NG from a pipeline or safety valve, if ignited causes a jet flame. The direction and

tilt of this jet flame will depend on the prevailing wind direction and velocity. The damage in case of

such type of jet fire is restricted within the plant boundary limit. However, the ignited jet may impinge

on other nearby vessel / equipment / pipeline causing a domino effect.




Page | 7.15

Fire Ball:

This happens during the burning of NG gas cloud, the bulk of which is initially over rich (i.e. above the

upper flammable limit). The whole cloud appears to be on fire as combustion is taking place at eddy

boundaries where air is entrained (i.e. a propagating diffusion flame). The buoyancy of the hot

combustion products may lift the cloud form the ground, subsequently forming a mushroom shaped

cloud. Combustion rates are high and the hazard is primarily thermal.

UVCE (Unconfined Vapour Cloud Explosion):

UVCE stands for unconfined vapour cloud explosion. The clouds of NG mix with air (within flammability

limit) which may cause propagating flames when ignited. In certain cases flame may take place within

seconds. The thermal radiation intensity is severe depending on the total mass of Gas in cloud and

may cause secondary fire. When the flame travels very fast, it explodes causing high over pressure or

blast effect, resulting in heavy damage at considerable distance from the release point. Such explosion

is called UVCE (Unconfined Vapour Cloud Explosion) and is most common cause of such industrial

accident.

7.4.8 CONSEQUENCE ANALYSIS

Based on the existing and proposed storage facilities, certain hazards have been identified and their

consequences modelled mathematically, using HAMS-GPS software. HAMS-GPS, constitutes one of

the most comprehensive Windows based software package that conforms to the relevant International

Standards to study EHS management and advanced consequence modelling and Quantitative Risk

Analysis / Assessment - QRA Study Softwares.

In the risk analysis study, probable damages due to worst case scenarios were quantified and

consequences were analyzed with object of emergency planning.

The two materials viz. FO/ HSD materials falls into Petroleum Class B i.e. materials having flash point

above 23oC, smaller leaks from the tanks would require source of ignition for fire. Hence, catastrophic

failure have been considered for worst case scenarios.

7.4.8.1 MAXIMUM CREDIBLE LOSS SCENARIO (MCLs)

MCLS assumes maximum inventory of hazardous chemicals and worst weather condition prevailing at

the time of failure. Further, no credit is given for the safety features provided in the facility to determine

maximum possible damage from the scenario selected. In reality, leakage of hazardous chemical will

be smaller in magnitude. Also the leakage will be detected immediately by plant operating staff then

initiate various mitigation measures to prevent any disastrous situation.

7.2 ECOLOGICAL DAMAGE ASSESSMENT &

REMEDIATION PLAN

7.2.1 PRELUDE

The primary concern of remediation plan is to evaluate the extent of environmental damage done due

to project operation in the absence of environmental protection measures. The traditional knowledge of

the project is being utilized to derive the extent of damage and plan remediation with time bound action

plan and budgetary provision.

The partial construction activities for foundation of boiler & ESP were carried out, making it a violation,

they had applied under the violation window to SEIAA Gujarat as per the provision of Notification S.O.

804(E) dated 14/03/2017 & its amendment S.O. 1030(E) dated 08/03/2018. In this matter, the Terms

of Reference (ToRs) have been awarded vide letter no. SEIAA/GUJ/TOR/1(d)/985/2018, dated 26th

Sep 2018.

Status of project

• The cost of civil construction/ erection so far incurred is approx.1.1 crore. The cost of structural

construction and part of equipment so far installed is approx. 6.9 crore. Thus total cost of the

activity completed is approx. 8 crore. The cost of pending activity and equipment is approx. 34

crore.

Partially completed construction work:

o The levelling and marking of the area for the boiler is carried out and followed by digging and

excavation of the soil for foundation.

o The concrete foundation for boiler & ESP has been raised up to 400 mm above ground level

and there after steel structure fabrication for boiler & ESP has been started.

o The steel fabrication has been brought to the site in pre-fabricated condition and assembled at

the site.

o The steam turbine generator building foundation has been completed. Structures like beam and

column, at the level of 5 meter and 7.4 meter level elevation has been carried out and there

after work was stopped.

o The boiler & ESP have been installed on foundation & necessary steel structure work has been

done as above.

o Construction activity has only been partially completed. So operation is yet not started.

7.2.2 ECOLOGICAL DAMAGE ASSESSMENT & REMEDIATION PLAN

(1) Scope of the work:

The study reveals the extent of environmental damage caused by the project operation without formal

statutory approval. The impact due to unscientific measures and the absence of EMP undertaken if any

will be elaborated. The measurable impacts will be ascertained with the extent of damage done with

the financial liabilities to bridge gap of stipulated environmental norms will be undertaken.

(2) Introduction:

There are various parameters which may degrade environment of the surrounding area due to project

activity. Environment damage & assessment has been studied in comparison to the earlier

environmental status before the start of the activity considering the following parameters:

1. Air Pollution

2. Water Pollution

3. Solid Hazardous Waste

4. Noise & Vibration

5. Greenbelt

6. Hydrogeology

7. Risk Hazards/ Occupational Health & Safety

8. Soil Conservation

(3) Deviation from regulatory frame work:

Project proponent has started construction work before getting Environmental Clearance under EIA

Notification, 2006.

(4) Baseline Environmental Status:

Baseline Environmental Status has been established by following necessary Guidelines and Methods

for Monitoring, Sampling & Testing of Environmental Samples. The details of Baseline Studies are

presented in Chapter 3 of EIA report.

(5) Environmental Impacts for Ecological Damage Assessment

Air Pollution

The construction quantum is significantly high, resulting in considerably high fugitive emissions,

Exhaust of construction equipment & machineries and vehicles movement within site. The main fugitive

emissions from the construction site are identified to be particulate matters (Dust & Cement Particles

and particles of other construction materials like sand & grit etc.). The particulate settled on vegetation

may lead to hindrance in photosynthetic activity of affected flora. Similarly, particulate inhaled by human

& other fauna may lead to serious pulmonary health effects.

However, the overall impact due to partial construction work will be marginal, reversible, localised and

is not expected to contribute significantly to ambient air quality.

Water Pollution

The construction work of the project needed 8 KLD freshwater which was met from GIDC Water Supply.

The ultimate source of the water is surface water and the same is adequate to cater the demand of all

users in the project region. The area is considered safe in terms of availability of water.

Further, total wastewater generation from the project is estimated to be around 1.62 KLD which is

basically domestic sewage from domestic activities.




Remediation Plan

Page | 7.2.3

The domestic sewage had been disposed off through septic tank & soak pit system which has resulted

in loss of usable water @ 1.62 KLD. It could be appreciable efforts & action if the project would have

utilized the sewage (1.62 KLD) after treatment in ETP which may have reduced the freshwater

requirement upto 20.25%.

Hence, there is no major impact envisaged on water resources and on water environment during the

partial construction work.

Solid Hazardous Waste

It has been estimated that during construction, generation of excavated soil was about 17500 m3. The

excavated soil has been utilized for landscaping. The construction waste has been reused as filler up

to plinth level. The municipal waste generation during construction was about 8-10 kg/day which has

been segregated into biodegradable and non-biodegradable wastes and collected in separate bins and

disposed through approved mode along with the domestic wastes from existing unit.

Hence, any major impact due to waste disposal during waste from the projects is not noticed. However

some minor impacts due to negligible contamination of air & soil have been considered which would

not have caused any significant impacts on ecology.

Noise & Vibration

Noise generation during construction works has been noticed to be significant due to operation of heavy

equipment/machineries, mechanical works like metal cutting & grinding etc. as well as due to increased

traffic. This generated noise may have resulted in considerable impacts on the fauna dwelling is on the

vicinity of the site. The noise level in the project site has not been monitored during the completed works

but it is assumed that the noise level in site would have reached the level of 75-80 dB(A) during

construction works. However, the incremental noise generated will be marginal, localised & temporary.

Greenbelt

The greenbelt is already created by the company in premises in about 6562.74 m2 area (about 10%

area of total land). No additional Greenbelt is done for proposed project. Hence, the beneficial impact

of greenbelt has been considered for further study of ecological damage assessment but exempted

from estimation of cost of damage & remediation.

Hydrogeology

Groundwater has not been tapped for the partial construction activities. Hence there will be no impact

on ground water. Also, borewell recharging is not permitted in GIDC. However, rain water harvesting

is recommended.

Presently at project Site, rainwater is collected from chips godown in the open pond. The rooftop area

is approx. 1150 m2. The rainwater harvesting potential indicates that company has harvesting potential

of about 1703 m3/annum of rainwater.

Risk Hazards/ Occupational Health & Safety

During the partially completed construction work, no any incident of adverse impacts on occupation &

public health & safety has been noticed. Hence the impacts on occupational & public health & safety

have been exempted for further study of ecological damage assessment & estimation of cost of damage

& remediation.

Approximately 36 workers have been engaged in construction work. Considering, cost for health

checkup per worker is Rs. 500 & cost of PPE per worker Rs.500. The total cost under this head was Rs

37800. Hence, cost of OHS per day was Rs.165.79.




Remediation Plan

Page | 7.2.4

Soil Conservation

Excavation for foundation of the project must have resulted in the loss of top soil. Major impact on land

environment from excavated material during excavation for building foundation.

The other construction waste generated would include debris, concrete, steel and other metals, bricks,

pallets, packaging and paper products, railings, door and window casings, fixtures, tiles, furnishings

etc.

The project proponent has adopted the following measures to prevent contamination of soil or damage

to the land environment.

Construction wastes stored in dedicated temporary storage facilities and utilised for PCC, Filling

etc.

Stock piling of excavated soil and water sprinkling on stock pile to stabilised the dust. The

excavated soil has been used for landscaping and other filling requirement.

An amount of Rs. 12.25 lakhs as recurring was spent by the project proponent for stabilisation and

reuse of excavated soil.

The overall impact on soil quality due to partial construction work will be marginal & localised.

Land

The proposed installation will be accommodated in the existing land & some part of proposed

installation will be done on additionally adjoining land. The existing plots and additional land are situated

in Notified industrial area of Sarigam.

Further, it is verified that there were no vegetation clearance needed for development of project

because the project site used was open land. Hence, impact on ecology due to clearance of vegetation

is not observed. The project proponent has utilized area admeasuring about 6562.74 m2 for healthy

greenbelt by planting trees, herbs & shrubs, which is found beneficial to the ecological layout and

environmental health of the area. Hence, there will be no impact on land.

Socioeconomic Layout

About 36 persons have been appointed for partial construction of the project. Proponent had provided

this employment through contractors and all temporary construction staff were from local area. Hence

no construction camp had been provided. Therefore no major issue of disturbance to the local social

structure has been occurred. Also all necessary facilities had been provided to labours in premises

during the construction operations by the proponent. Hence issue of social conflict due to use of local

public facilities by the labour has not been observed. Beside these, no other issue of local

socioeconomic layout has been observed. In furtherance to the above, it has been noticed that the

employment of local people has resulted in considerable moderate economic benefit to the local people.

Thus the overall impact of completed work of project on socioeconomic layout has been found to be

beneficial.

Manpower & Recruitment

About 36 persons have been employed as contractual appointment by the contractor for the partial

construction of the project. This has led to moderate temporary beneficial impacts due to the

improvement in employment status of the area. Also appreciable moderate economic benefit is also

noticed due to the indirect employment which has benefited the local people. However, the recruitment

of these human resources has led to generation of considerable quantity of domestic sewage & waste.




Remediation Plan

Page | 7.2.5

Loads on Public Amenities

The load on public amenities due to the completed work has been noticed due to the use of freshwater

for the project and the increased traffic on the road. Especially the load on road network due to

increased traffic of the project has been identified as considerable but the change in level of service

category of local road has not been downgraded. The proponent has taken good care for traffic

management but the residual impacts were considerable. Such increase traffic might have resulted in

some minor impacts on ecological layout of the route of transportation for the project.

Transport

Transportation activities of the project have been done through the local road network which has led to

considerably increase traffic on the road network utilized. This has resulted in increase in rate of

exhaust from vehicles on the roads. This increased exhaust emission might have caused some non-

measurable adverse effects on ecological layout.

(6) Assessment of Environmental Impacts, Ecological Damage & Remediation Cost:

After identification & determination of environmental impacts of the project responsible for ecological

damage, numerical assessment of identified/determined impacts has been done. Based on this impact

assessment numerical analysis of information has been done to determine the cost of ecological

damage & remediation. The details are presented in subsequent sections.

Criteria for Assessment of Environmental Impacts causing Ecological Damage: The following

(7) Remediation Action for Ecological Damage Assessment and Natural & Community

Augmentation Plan:

Considering the above description & assessment, it has been found that most of the impacts were

reversible & short term except the long term impacts on water environment. The damage caused to the

environment has also been found restored in almost all cases except land, water, air & biological

environment. Considering this, measures & action required for remediation for restoration of ecological

damage has been planned and the details of same are tabulated below.

Table 7.2.3: Remediation Plan for Ecological Damage Restoration

Sr. No.


Mitigation Measures Implemented/ Planned

Measures & Action Required for Remediation for restoration of ecological damage

1 LAND Unused land within existing premises & adjoining plots (industrial land) with Greenbelt.

Waste management by reuse and disposal through approved mode

To restore the minor effects caused by project additional voluntary Greenbelt Development shall be done which is also needed for restoration of damage of other environmental attributes.

2 WATER Use of Water supplied from GIDC, No direct use of surface water or groundwater, RWH System

Soak Pit (during construction) and Reuse of construction wastewater

In addition to this, it has also been noticed that high water consumption activities of construction work has already been completed which has resulted in significant loss of ultimate water supply resource. This impact is reversible naturally but with significant uncertainty.




Remediation Plan

Page | 7.2.9

Sr. No.




Reuse of wastewater for construction & irrigation

Longtime/ lifetime Rainwater Harvesting & Recycling/Reuse of Sewage with all best operational practice & maintenance shall be ensured.

Hence, it is recommended that all necessary facilities for Rainwater Harvesting & Reuse/Recycling of Sewage shall be maintained. It is also recommended that the regular operation of these facilities along with all necessary maintenance shall be ensured for lifetime.

3 AIR Water Sprinkling, Closed storage, barricading around site

Adequate Stack, HSD as Fuel, PUC for Vehicles

The identified impacts are limited to very short time & localized impacts which are naturally reversible. This natural reversal process is quite rapid in case of Particulate if emission of PM is eliminated from project.

The mitigations provided is effective but need further care in implementation for enough time to restore the damage air quality.

Greenbelt development & maintenance as well as adequate stack for DG sets & their maintenance is needed for life time.

Water sprinkling in construction area and unpaved road is needed during Construction phase.

Internal area other than Garden & Greenbelt area shall be paved.

4 NOISE No high noise generating operation during night time, turning off idle vehicle& machines

Minimal transport during night time, Restriction on loud horn & unusual acceleration of engine

The impact identified is highly reversible and the damage cause was very temporary which has been restored naturally. So no specific restoration action is required except action for prevention of high noise in future especially by acoustic enclosure for DG Set.

5 SOCIO-ECONOMIC LAYOUT

Priority to local in employment

Priority to local contractors & vendors

No permanent or long term damage has been identified but long term benefits have been observed.

However, a written signboard for environmental awareness especially for efficient use & conservation of water, conservation & protection of vegetation & ecology in general as well as saving of power, road safety & basic traffic rules etc. is recommended.

Provision of CER for social welfare and Community Resource Augmentation




Remediation Plan

Page | 7.2.10

Sr. No.




shall be ensured with budgetary provision of 84 Lakhs.

6 PUBLIC AMENTIES

Proper Traffic management & transport schedule and

Minimal use of freshwater, Rainwater Harvesting for groundwater recharge

The damage identified is found to be highly reversible and related with actual traffic operation of construction phase. Hence, it is noticed that this damage is restored naturally with cessation of major transportation needed for construction work of project.

It is recommended that for remaining construction work transportation shall be done by proper scheduling for prevention of high traffic density on road due to the remaining work.

In addition to this, it has also been noticed that high water consumption activities of construction work has already been completed which may have resulted in considerable issue of water availability to public. Now this issue will not arise as the water requirement of the project will be significantly lower during construction phase and water conservation & rainwater harvesting action recommended for water environment will reduce this impact to highly acceptable level.

However, it is recommended that all measures suggested above for water environment, air environment and Road safety & traffic management shall be implemented for efficient restoration & further prevention of damages identified for Public amenities.

Provision of CER for social welfare and Community Resource Augmentation shall be ensured with budgetary provision of 84 Lakhs.

7 ECOLOGICAL LAYUT

Greenbelt Development; Air pollution reduction measures; Treatment for septic tank/ Soak pit & wastewater management; minimal water consumption; wastewater & waste reuse/recycling as mentioned above.

The moderate long term damage has been identified due to stress & quality of water resources (abiotic factor of ecology). This damage is found to be reversible but at moderate rate & considerable uncertainty. So action & measures suggested for water environment shall be strictly implemented.

Similarly short term naturally reversible damage to air & noise environment has also been caused which has already

Page | 7.2.11

Sr. No.




been reversed except the residual minor impacts of particulate settled in natural vegetation. Hence, it is recommended that efficient & strict implementation of measures & action plan suggested for Air environment along with greenbelt development & maintenance shall be ensured for rest of the life span of the project.

(8) Conclusion:

As per as per indicative guideline provide in TOR, the calculated amount of remediation plan and natural

and community resource augmentation plan worked out to be Rs. 14,24,644 for a year.

CER cost for the proposed project as per MoEF&CC’s O.M. No. F No 22-65/2017-IA-III dated

01/05/2018, is Rs.42 Lakhs which is 1% of the total cost of the project Rs. 42 Cr.

As per recommendation by the SEAC and finalization by the regulatory authority, the bank guarantee

will be submitted to GPCB equivalent to the amount of remediation plan and natural & community

resource augmentation plan or equivalent to CER amount, whichever is higher. As the CER cost is

higher than amount of remediation plan and natural & community resource augmentation plan, the

amount of bank guarantee will be Rs. 42 Lakhs.



Chapter-8: Project Benefits

8. Project Benefits 8.1 PROJECT BENEFITS

This chapter presents the summary of tangible and intangible benefits due to the proposed project.

M/s. JBF Industries Ltd., is located at GIDC Sarigam, Dist. Valsad. The existing plant is established in

the year 2006, wherein manufacturing of Polyester Chips & generation of Captive Power (9.9 MW) are

done.


change in fuel for 9.9 MW captive power generation.

Since, the proposed project is for amendment in Environmental Clearance for existing polyester chips

manufacturing plant for change in fuel for 9.9 MW captive power generation, there would not be any

major potential of development or improvement of physical & social infrastructures and hence

improvement in infrastructure is not envisaged to be major. However, the project benefits of proposed

amendment project as described below.

In existing operations, the unit has a power requirement of 9.5 MW. The total requirement is

fulfilled by DGVCL.

After proposed amendment project, total 10.4 MW power will be required. Out of which 9.5 MW

for process plant will be met by proposed power plant & 0.9 will be fed from DGVCL.

Thus electrical energy cost can be reduced in the range of Rs. 5.95 per unit after considering

interest and depreciation.

There will be reduction in the total load on the electricity department which is also generating

electricity by Coal.

The construction and commissioning phase will require a substantial man-power and resources. The

unit has proposed to employ local contractual services for these phases. Hence, with the growth in the

economic conditions the project may lead to growth in the social stature & improvement of the quality

of life in the surrounding area.

11.5 ACTIVITIES, IMPACTS & MITIGATION MEASURES

11.5.1 AIR ENVIRONMENT

(a) During Construction and Commissioning phase

• The main source of dust emissions during the construction phase will be from excavation during

foundation, levelling of surfaces after foundation works, transportation of construction materials

and workers etc. However, the overall impact of these emissions will be short term, reversible,

localised and is not expected to contribute significantly to ambient air quality.

(b) During Operation phase

• The predicted level of criteria pollutants in the ambient air are well below the limits as prescribed

under the National Ambient Air Quality Standards (NAAQS, 2009) and hence the impacts in terms

of change in prevailing ambient air quality status can be acceptable for the proposed project with

installation and proper operations of APCM like ESP & lime dosing.

• There will be no process gas emission from proposed project.

• Fugitive emissions are likely to occur mainly during transportation, handling and storage of the

coal, limestone & fly ash. Coal/ Limestone should be stored in covered storage facilities to prevent

generation of wind-blown dust/ fugitive emissions. Water sprinkling system should be provided in

coal storage yard.

11.5.2 NOISE ENVIRONMENT


• Construction activities such as operation of construction equipment, transportation of equipment,

man and material etc. are likely to cause an increase in the ambient noise levels. However, the

incremental noise generated will be localised & temporary.


• The major noise generating sources from the proposed project would be boilers, fans, pumps,

cooling towers, steam turbine, etc. From the modelling studies, carried out for the prediction of

ambient noise due to the proposed project, it was observed that the incremental noise levels from

the proposed project will not have any appreciable impact outside the plant boundary.




Page | 11.6

11.5.3 WATER ENVIONMENT


• Water requirement during construction phase will be met through the existing water supply

resources of GIDC water supply department. The total water required will be well within the

sanctioned drawl capacity by GIDC water supply department.

• There will be no impact on ground water level as groundwater will not be abstracted.

• The domestic wastewater i.e. sewage generated will be treated in existing ETP discharge through

into GIDC underground drainage.

• Hence, there is no impact envisaged on water resources and on water environment during the

construction phase.


• The impact on water quantity will be negligible as the source of water is GIDC water supply dept.

• In existing operations, the fresh water requirement is @1023 KLD which will increase to @1091

KLD after proposed amendment project.

• In existing operations, total wastewater generation is @725 KLD bifurcated as @50 KLD as

domestic waste water, @675 KLD as industrial waste water to ETP.

• After proposed project, additional 32 KLD industrial wastewater will be generate, which will be

treated in existing ETP followed by RO. The quantity of recycling effluent from RO will be

increased@30 KLD. There will be no additional wastewater discharge into GIDC underground

drainage. The total discharge into the GIDC underground drainage will be @544 KLD as per

existing permitted quantity.

• Existing ETP is adequate to cater the treatment for proposed industrial waste water generation

quantity.

• Improper storage of Coal & fly ash can either result in contamination of surface water if coal/ ash

particles are washed off with storm water during monsoon or in contamination of ground water

due to leaching in soil. Hence, it is suggested that closed storage area should be provided for coal

with impervious bottom and leachate collection line (connected with ETP) and Fly ash should be

stored in Silos.

• Thus, looking to the overall scenario no significant impact on the water environment is envisaged

with proper implementation of suggested measures.

11.5.4 LAND ENVIRONMENT


• The proposed project is to be established at land designated for industrial purpose. Hence, there

will be no change in the land use/land cover in the study area after the establishment of the

proposed project.


• Impacts on soil quality can occur due to the particulate emission from transportation, handling &

storage of coal and ash as well as improper disposal of fly ash (non-hazardous waste). To

prevent these impacts, all necessary mitigation measures suggested for control of emission of

particulates from boiler as well as coal & ash handling operations are provided

• In furtherance to these, the impacts on landuse-vegetation/plantation area can occur due to

settling of particulates emitted from project on leaves of plants & tree of the area, hence, for

control of particulate emissions, efficient functioning of control measures should be ensured

• Thus, the impacts are likely to be insignificant with implementation of adequate control measures.




Page | 11.7

11.5.5 SOCIO-ECONOMIC ENVIONMENT


• The local residents will be employed contractually as per their skill and aptitude.

• All the necessary health and sanitation facilities will be provided at the construction site.

• The social impacts during construction phase are likely to create direct and indirect employment

including business opportunities for the local people, which will improve their economic conditions

and quality of life.


• The project site is well connected with the National highway and there will be no requirement of

additional infrastructures.

• Impacts on social environment are likely to occur mainly due to dust emission from

transportation/storage, handling of coal/ ash, emission from utility-boiler. To prevent impacts

occurred from particulate/ dust emission, all necessary mitigation measures suggested for control

of emission of particulates from boiler as well as coal & ash handling operations should be

provided.

• All necessary mitigation measures suggested for noise control should be provided to reduce the

impacts of noise generation due to CPP operations.

• Existing road network is adequate to cater additional traffic load due to proposed project.

• All safety measures and required essential plans should be provided & implemented for safety,

disaster & emergency action, as mentioned in RA Report for proposed project.

• Approximately 20 nos. of people are expected to benefit from direct employment for the project.

• Social development program should be conducted as the part of CER activities.

• Minor beneficial impacts on employment & contract services are likely due to increase potential of

indirect employment in transportation activities for coal & ash

• Thus, the impacts on socio-economic environment would not be major, if suggested EMP is

implemented.

11.5.6 ECOLOGICAL ENVIRONMENT


• The proposed projects will be established on open land as well as plot adjacent to existing site,

having negligible vegetation cover. Hence, no tree cutting activities will be involved.

• Minor impacts on local flora and fauna are anticipated due to air emissions and noise generated

during construction activities. However, these impacts would be short-term, localised and would

be restricted within project site.


• To ensure there will be no major impacts on ecology, proponent should provide all other

mitigation measures as suggested for prevention of pollution of air, water, land/ soil and noise.

• Appropriate air pollution control systems with online monitoring system should be installed to

meet the emission standards stipulated for PM, SO2 and NOx by State Pollution Control Board.

• Coal & ash particle can get washed off from storage area with storm water during rainy days

which may get mixed in to the nearby river, which can adversely affect the aquatic ecology.

Hence, it is suggested to provide closed storage area for storage of coal & silo for fly ash.

• Since, the high noise generation from turbine can impact the local faunal species, it is suggested

to provide the effective noise control & noise attenuation measures.

• Contribution should be made to ecological welfare & forest development activities conducted by

Govt. Organization, NGOs and other such organizations.




Page | 11.8

• Regular monitoring of Valued Environmental Components as per Environmental Monitoring

Programs designed for the project should be carried out.

11.6 POST PROJECT MONITORING PLAN

As a part of EIA study, a post-project monitoring plan has been prepared and necessary suggestion &

guidelines for post project monitoring are provided therein. The capital cost for proposed project will

be Rs. 42 crores. The Capex for implementation of Environmental Management Systems will be Rs.

4.8 crores and Opex for environment protection & continual improvement will be Rs. 3.3 crores/

annum.

Post project monitoring plan covers sampling & analysis of water, air, emission, wastewater, noise,

hazardous wastes. The environmental compliance report should be prepared and submitted as per

the regulatory guidelines.

11.7 ADDITIONAL STUDIES

The Risk Assessment study involving consequence analysis related to fire/ toxic dispersion due to

storage/ handling of fuel and raw material has been carried out. Accordingly, a Disaster Management

Plan has been prepared. The suggestions cited in RA report should be implemented for fire &

explosion hazard prevention, emergency management, other potential occupational health hazard

prevention, safety gear etc. A safety & environment management cell has been designated to

manage the responsibilities delineated in the EMP.

The proposed project will be established on the existing site as well as additional land within the

GIDC, which is in possession of JBF. Hence, there will not be any resettlement & rehabilitation due to

the proposed project. Therefore, R&R study has not been conducted for the proposed project.

Public consultation is applicable to the proposed project as per the TOR granted by SEIAA Gujarat.

Hence, Environment Public hearing will be conducted as per the schedule of state pollution control

board and necessary action to address the issues raised in Environment Public hearing will be

initiated after public hearing.

11.8 ECOLOGICAL DAMAGE ASSESSMENT & REMEDIATION PLAN

The partial construction activities for foundation of boiler & ESP has been carried out. The impacts

due the activity is marginal & localized.

As per as per indicative guideline provide in TOR, the calculated amount of remediation plan and

natural and community resource augmentation plan worked out to be Rs. 14,24,644 for a year.

CER cost for the proposed project as per MoEF&CC’s O.M. No. F No 22-65/2017-IA-III dated

01/05/2018, is Rs.42 Lakhs which is 1% of the total cost of the project Rs. 42 Cr.

As per recommendation by the SEAC and finalization by the regulatory authority, the bank guarantee

will be submitted to GPCB equivalent to the amount of remediation plan and natural & community

resource augmentation plan or equivalent to CER amount, whichever is higher. As the CER cost is

higher than amount of remediation plan and natural & community resource augmentation plan, the

amount of bank guarantee will be Rs. 42 Lakhs.

11.9 PROJECT BENEFITS

Approximately 20 nos. of people are expected to benefit from direct employment for the project.

Benefits to contract services is also expected due to increase potential of indirect employment in

transportation activities for coal & ash. Thus, the potential of employment will be beneficial to the local

people in long term with routine human resource management plan of the company.

The company will have to spend Rs. 84 lakhs (double the applicable amount) for the next five years

for corporate environmental responcibility as per the awarded TORs. The CER activities planned by

the company will be considerably beneficial for the health, education, community developement,




Page | 11.9

socialwelfare etc. These all together with the economic benefits of the proposed project will result in

further benefits in terms of the literacy level, primary and middle level education and on health

facilities.

11.10 ENVIRONMENT MANAGEMENT PLAN

Environmental Management Plan has been formulated as a part of the EIA study. The major issues of

predicted impacts of proposed expansion project have been considered for delineation of necessary

action plan. The EMP has been formulated considering all necessary mitigation measures to prevent/

minimize/ eliminate the environmental impacts as well as to delineate implementation schedule and

responsibilities. Necessary action plans for ecological conservation & welfare, social upliftment by

CER, greenbelt development, energy efficiency & conservation and resources conservation through

“Cleaner Production Activities” have been covered in the EMP prepared for the proposed project.

11.11 CONCLUSION

As evaluated and shown at Chapter 4, the cumulative value of significance of the project, in terms of

the impacts on the environment, without mitigation measures and with mitigation measures works out

to be, (-) 35.55 and (-) 8.20 respectively, which indicates that with the implementation of the mitigation

measures, the negative impacts of the project can be reduced significantly and brought down to

acceptable levels.

The proponent of the project has agreed to proceed in line with the EIA agency’s comments and

suggestions to mitigate the adverse impacts to the most techno-economically viable extent
