expansion units.

1.1.7 Process

The Imported Coal (~4,200 Kcal/Kg GCV) will be fed to furnace of the CFBC Boilers (2 x 180 TPH) through feeders

from the Coal storage. Coal will be mixed with Limestone to reduce SOx emission. This mix will be fired in the

furnace by means of FD-Fan air. The saturated steam is generated in the Boiler drum and passed to the Primary,

Secondary & final super heaters to get the superheated steam @ 535°C & 109 ata from the Boilers. The

superheated steam is fed to the Steam Turbine and it rotates the steam Turbine which is coupled with Generators (

2 Nos). The power of 67 MW will be generated in the Generators and distributed in house. Flue gas shall meet the

M/S. MEGHMANI




statutory norms. To comply emission norms, necessary dosing of lime stone shall be done via feeder. Design of

ESPs will be as per the state government norms and MoEF&CC Guidelines / standards.

1.1.8 Waste Water

Steam condensate will be recycled back into the process. There will not be any generation of process effluent.

Boiler blow down will be directly used for cooling tower make up water while other effluents will be collected into

collection tank where pH correction will be carried out if required. Then the treated wastewater will be used for

dust suppression, in coal handling and & in existing ash handling unit. Thus, zero effluent discharge criteria for new

power plant will be met. Rest of the effluent from other plants will be treated in existing ETP and will be disposed

to GIDC Drain after meeting the GPCB effluent discharge norms.

1.1.9 Air Emissions

Due to the proposed project following types of air emissions are envisaged:

Point Source: SPM, SO2 & NOx from flue gas stacks;

Area Source: SPM emissions from coal stock piles;

Line Source: Vehicular emissions like SPM, CO & HC’s from exhaust of the vehicles;

Fugitive emissions from coal handling & storage are envisaged.

1.1.10 Hazardous and Other Solid Wastes

The following solid / hazardous wastes will be generated during operations:

Hazardous Waste: Used Oil;

Non-Hazardous Waste: Fly Ash;

Domestic Solid Waste: Paper and Food waste;

Small amounts of E-waste and scrap.

These will be managed as per the applicable Rules, mainly, Hazardous Waste (Management, Handling, Storage and

Transboundary) Rules 2016, as amended till date.

1.2 DESCRIPTION OF THE ENVIRONMENT

1.2.1 Study Period and Area

Baseline environmental study was carried out in December 2016 – February 2017 (Winter Season) within 10 Km

radius of the project site.

Air monitoring was carried out at 8 locations. Noise monitoring was carried out at 5 locations. Surface water

samples from 8 locations including ponds and estuary were collected, ground water samples from 8 location

Borewells/ Openwells and soil samples from 6 locations were collected and analyzed.

1.2.2 Land use and Land cover

There are around 45 major industries in the study area. Land use of study area has been broadly covered by

Vegetation cover (~29.2%), Wasteland (19.3 %), Agricultural land (~16.3%), Water Bodies (16.1%), Habitation

(~6.2%), Forest Area (1.5%) and Others like salt pans, grass cover & creek as (11.6%).

The crops cultivated in the study area are cotton, Castor Chillies and Wheat are grown in this region.

1.2.3 Meteorology

Based on the long-term climatological tables as per Indian Meteorological Department (IMD) for Broach (Bharuch)

(Station ID: 42841), during winter season, the maximum & minimum temperature recorded are 33.5°C & 11.3°C

M/S. MEGHMANI




respectively. The mean hourly relative humidity recorded during morning, remains between 64 – 74% and in the

evening, remains between and 34 – 44%. Pre-dominant wind direction is from NE (48.5%).

Site specific meteorological data was collected by installing automatic meteorological station at roof top of SEZ

office, which is ~ 8.30 Km in W direction from the project site.

Maximum and Minimum temperature were recorded as 36.7°C (in the month of April) & 15.2°C (in the month of

January) respectively. Mornings are more humid than evenings and relative humidity ranges from 78 – 86% in

monsoon mornings to 34 – 43% in winter evenings. Average wind speed was 3.1 m/sec & Predominant wind

direction was from NE to SW direction (27%) direction.

1.2.4 Ambient Air Quality

It is noted from Table 1-4 that maximum PM10 results exceeds NAAQS at all locations except near forest area and

salt pan and maximum PM2.5 results exceeds NAAQS at Vadala Crossing which could be due to:

Vehicular movement on the “kaccha” roads of the villages;

Industrial & infrastructure development activities in study area (PCPIR & residential projects);

Rural activities like burning of cow dung for household purposes like using it in “chullas”.

It is observed from the Table 1-11, that at different locations:

The porosity ranged from 55 - 61% and water holding capacity varied from 52.40 - 62.30%;

M/S. MEGHMANI




The permeability was ranged from 2.24 - 10.7 mm/hr;

The EC of soil ranged from 0.140 - 0.808 dS/m;

The pH of soil ranged from 7.63 - 8.36;

Among water soluble cations predominance of sodium was seen followed by Ca, Mg and K.

Soil texture in all the soil samples was silty clay- clay loam, hence whatever variation observed was mainly due

to variation in organic matter content of soils.

Major crops grown are Tuver Wheat and Cotton, among vegetables Rigan, Tomato and Val, Valpapadi are grown,

and horticulture activity is very less it includes Keri, Chikoo, Papaya and Banana.

Among Fishery Bombay duck constitutes the dominant fishery (13%) of the region.

Mangrove flora is dominated by Avicennia marina and Rhizophora mucronata. Healthy growth of mangroves has

been reported from the banks of Ban Khadi and Ghugar Khadi. Halophytes like Sueda maritima and Salichornia

brachyata are very common in the coastal area.

Marine biodiversity study shows that, buffer zone supports 16 nos. of phytoplankton and zooplankton genera.

1.2.11 Socio-Economic Environment

Social studies were carried out within the study area. Brief highlights are as follows:

Population and its distribution: There are 21 villages, with a total population of 40,501 persons and 9,432

households;

Sex Ratio: The total population of male is 22,944 and female population is 17,557;

Schedule Caste & Schedule tribe: SC population is 4.4 %, total ST population is 20.3% of the total population.

Literacy rate: Average literacy rate is 74.35%;

Educational Facilities: Primary schools are available in all the villages; the highest educational facility available

is till Secondary school;

Medical facilities: Medical facilities are limited. Apart from Dahej most of the villages are devoid of the health

facilities. Primary Health Centre is present only in the Dahej village;

Drinking water: Well and tank facilities are sufficiently present in villages but the water requirement of the

village is not adequately supported because of it being saline unsuitable for the drinking purpose;

Household facility: Out of the 41 household survey done 18 were having Pucca houses, 7 Semi Pacca, 45

Kutcha where as 1 house was shanty;

Transportation Facility: The study area is well connected with road, the nearest railway station is Bharuch and

Dahej;

Power supply is available in all villages;

M/S. MEGHMANI




Economic Profile: Bulk of the population falls in the daily wage earner category working in as agricultural labour

or in the private companies as the contractual labour 6.8% of the population were having stationary, grocery,

tea stalls etc., 2.7% of the population were earning from the livestock being an industrial area most of the

people as contractual labor in GIDC.

1.3 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

1.3.1 Air Environment

Dispersion modeling (using “AERMOD” modelling software) was carried out for point and area sources only.

This indicates:

Maximum Incremental GLC’s for PM10, SO2 & NOx remain within 750 m from the project site;

Air impacts are not expected to cause any effect on vegetation and human settlements in the vicinity of the

project site.

Mitigation measures for air quality impacts are:

Adequate height of at least 65 m will be provided as per the statutory requirements;

Well-designed ESP having alteast 99.9 % efficiency will be provided to control PM emissions;

Limestone dosing in CFBC Boilers will be done to achieve sulphur reduction efficiency of alteast 95.8%;

Since the proposed technology is of CFBC, temperature will be controlled to prevent NOX generation;

Online sensors for SPM, SO2 & NOx will be provided with flue gas stacks which will be attached to CPCB & GPCB

servers;

Regular Work place monitoring will be done;

CAAQMS will be placed near admin building;

Adequate Bag filters will be installed in ash handling unit & coal yard;

Effective water spraying will be done on the access roads to control re-entrained dust during dry season (if

required);

Proper operating procedures will be followed during startup and shutdown;

Proper PPE like dust masks will be provided to workers and its use will be ensured.

1.3.2 Traffic

From the proposed project, ~100 trucks per day carrying coal, limestone, fly ash, etc. will be using the state

highway (SH-6) connecting Bharuch and Dahej, i.e. additional 22 PCU’s will be required. Based on the traffic survey

conducted on this road, it is noted:

Average peak hourly traffic on this route is 531 and 570 PCU respectively;

As per IRC, carrying capacity of this approach road is 3,600 PCU;

Thus, the maximum PCU on the road will be 553 (Bharuch to Dahej) and 592 (Dahej to Bharuch).

Thus, the road is capable of carrying the excess traffic due to the proposed expansion.

1.3.3 Noise Environment

Using “SoundPlan” Modelling software, due to the proposed activities it is predicted that 0.2 dB will be

increased during the day and 0.3 dB during the night in Industrial & Residential area.

This increase is negligible considering that the minimum noticeable increase by a human ear is 0.5 dB hence it

can be concluded that due to noise generated from the proposed project there will not be any impact on the

surrounding area.

M/S. MEGHMANI




1.3.4 Water Environment

Ground water is not abstracted for any plant activities since the water supply will be available on continuous and

uninterrupted basis from GIDC. The plant will be paved, therefore the likelihood of contaminants entering

groundwater and harming the same is improbable (i.e. unlikely).

The overall impact on surface water quality will be negligible by taking following precautionary measures:

Coal yard will be provided with proper bunds to avoid run-off contamination.

Maximum condensate will be recovered from the boiler to reduce the fresh water demand;

Rain water harvesting will be adopted for the conservation of water;

Regular maintenance of effluent treatment plant will be done to ensure smooth operation;

No discharge of untreated waste water on land;

Zero effluent discharge criteria for new power plant will be met. Rest of the effluent from other plants will be

treated in existing ETP and will be disposed to GIDC Drain after meeting the GPCB effluent discharge norms.

Separate drains for storm water and effluent will be provided for proposed expansion project to avoid any

contamination of surface water sources;

All chemical and fuel storage and handling areas will be provided with proper bunds & dyke walls to avoid run-

off contamination during rainy season.

1.3.5 Land Environment

The land use pattern of the project site will not get affected since it is within factory premises. Mitigation measures

for conserving land use and land cover will include the following:

The vegetation cover clearing will only be done on which construction will take place;

Reuse of earth material generated during excavation will be done;

Optimization of land requirement through proper site lay out design will be done;

Fly ash will be given to cement manufacturer, brick manufacturing unit and for road construction;

Storage areas for hazardous waste, fuel & raw material will be impervious and will be designed to prevent

Leachate penetration;

Generated hazardous wastes during project operation will be transported to an authorized TSDF operator.

1.3.6 Biological Environment

Since the proposed project is located within the existing factory premises there will be no significant or permanent

impact on the habitat structure of associated faunal diversity.

The existing unit already has well developed greenbelt consisting of 1,70,170 m2 (31.71%) against the 25% as per

the Existing EC (Condition No. XIII of Specific Condition of EC dated 09.08.2007). The existing greenbelt possess

~24,000 well developed trees consisting of 22 common species. Although additional 6,943 m2 (1.29%) of green

belt and additional 10,000 trees will be planted. Every year survival rate of the plantation within project site will be

monitored and accordingly greenbelt will be maintained.

As the emissions from the plant will be regulated and minimal with respect to the specified norms, and with a very

healthy existing developed greenbelt at the site in the form of several species, the biological environment will be

protected.

1.3.7 Socio-Economic Environment

While assessing the socio-economic and sociological impact including health impacts to surrounding population, the

upcoming project will bring job opportunities for the local people.

Environmental monitoring and management cost is estimated as total capital cost of ~INR 9.9 Crore and recurring

expenditure of ~ INR 1.4 Crore per annum.

1.5 ADDITIONAL STUDIES

1.5.1 Risk Assessment

During operation of the proposed power plant, following activities can pose hazards and risk to human and

surrounding environment:

Storage of HSD & Coal;

Contact with hazardous chemicals.

Maximum Credible Loss Scenarios were not considered due to the following reasons:

Proposed project is for expansion of 67 MW power plant, which only requires coal & limestone, which are non

hazardous. All other hazardous chemicals handled at site were already considered in previous EIA studies;

Auxillary power will be sourced from existing power plant / grid. Thus, no DG sets are proposed for startup of

proposed unit;

On the basis of chemical properties like flash point, phase of chemical, operating conditions and total inventory

etc., it is noted that in the proposed power plant project, there are no such storage of flammable raw materials

which can lead to uncontrolled release of hazardous material causing hazard.

M/S. MEGHMANI




As a general practice, following mitigation measures will be taken to reduce the risk of workers and staff:

Mitigation Measures

Spill management plan to prevent risk of spill which may cause health problem;

Off-site & Onsite emergency plan will be followed to tackle any emergency situation for proposed facilities;

Medical checkup will be carried out at an regular intervals;

During site preparation appropriate PPEs will be provided to site workers and staff members;

During operations, appropriate PPEs like Safety Goggles, Hand gloves, Clothing etc. will be provided.

1.6 PROJECT BENEFITS

During the construction phase around ~250 local skilled and semi-skilled workers will be employed and Existing

manpower (~570) is sufficient to operate proposed expansion unit;

The positives impact include enhanced indirect employment opportunities for transporters;

Other tangible benefits include development of various ancillary activities which shall generate indirect

employment to the locals.

1.7 ENVIRONMENT MANAGEMENT PLAN

An Environmental Management Cell with adequate professional expertise and resources is already in place to

discharge responsibilities related to environmental management including statutory compliance, pollution

prevention, environmental monitoring, etc.

EMP for suggested mitigation measures and monitoring plan will include:

Provision of SOPs and Emergency Response Procedures will be ensured;

Deploying experienced EHS head who will directly provide the status report to director on daily basis;

Proper inventory accounting & monthly review of non-compliances by plant head;

Monitoring for compliance of statutory conditions by EHS head;

Internal audit of hazardous waste storage area as per ISO system;

Timely submission of Form 5, Environment Audit Report, Hazardous waste manifest, Compliance of show cause

/ closure notice issued by regulatory authorities, etc.

Sufficient funds towards capital cost and recurring cost per annum will be provided and ensured that it is not

diverted for any other purpose.

1.8 CONCLUSION

The proposed power plant is required to cater captive power & steam requirement. The aim of the project is to

reduce dependency on the grid, thus reducing project and manufacturing costs. Based on the EIA study, the

following highlight emerges:

Land is available for setting up proposed plants within their existing premises;

No change in land use is envisaged;

Project has various locational benefits like availability of coal from nearby region;

Safety and environmental norms will be followed;

Recycle & Reuse scheme will be implemented to reduce water consumption;

Provision of air pollution control equipment, will lead to minimum adverse environmental impacts;

The project will generate employment for skilled, semiskilled, unskilled people during construction phase.
