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

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.

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.

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.
