Anticipated Environmental Impacts and Mitigation measures
Air Environment
In the present case,Industrial Source Complex [ISC3] dispersion model based on steady
state Gaussian plume dispersion, designed for multiple point sources for short term and
developed by United States Environmental Protection Agency [USEPA] has been used for
simulations from point sources.
Simulation Modeling studies reveal that, the maximum predicted short term 24 hourlyground level concentrations (GLCs) for SPM and SO2 during study period are 186.5g/m
3
and 46.6g/m3 respectively. The GLCs are expected to occur at 2.5-km in SE direction
from the main stack of the 2x125 MW plant. Air modeling estimations show that resultant
concentrations of SO2 and SPM due to the proposed project will remain well within the
National Ambient Air Quality Standards;
Limiting of pollutant discharge and minimizing its effect on air quality, within prescribed
standards, will be achieved; consequent to plant design for boilers and installation of
stacks of adequate height that provides better dispersion of pollutants. Consequently it is
unlikely to have any major impacts on local or regional air quality or to adversely affect
human health or status of pollution-sensitive vegetation, either locally or on nearby
terrain.
Water Environment
The total water requirement for the proposed power project is 825m3/hr, and it will be
met from the IGNP (Indira Gandhi Nahar Project). Proposed expansion project will not
extract groundwater and hence there will be no impact on ground water.
Wastewater will be suitably treated in STP/ETP and utilized for greenbelt development,
ash handling, dust suppression, service etc. Project is designed achieve zero discharge
concept. The sludge generated in the raw water treatment plant will be used as manure
in the greenbelt development

Solid Waste GenerationThe maximum production of ash estimated from the plant is 0.7MTPA. The entire
production of fly ash is proposed for consumption in cement manufacturing, brick
manufacturing and other prospective usages. 100% fly ash utilization will be achieved
from 4th year onwards as per the Fly Ash Notification of MoEF and subsequent
amendments.
Socio- Economics
The major economic impacts, which will accrue to the region, during the construction
phase and operation of the proposed power plant, will be an increased availability of
direct and indirect employment. Local people will be benefited after commissioning of the
proposed project in terms of petty to major contractual jobs and associated business
establishments.
Greenbelt Development
A 50 m wide greenbelt, consisting of at least 3 tiers around plant boundary will be
developed as greenbelt and green cover as per CPCB/MoEF, New Delhi guidelines. The
plant density will be of 1500 trees per hectare with local native species in the green belt.
Environmental Monitoring Programme
A structured and certified environment management system is suggested at the industry
level for ensuring that all the activities, products and services conform to the
environmental requirement. The Environment Management Cell will be responsible for
managing following activities related to environment function of proposed Power Plant:
Coordinate and manage the EMP implementation during pre-construction,construction and operation phase
Appoint dedicated environment staff to manage environmental monitoring
responsibilities

A well-defined environmental monitoring program would be emphasized with trained and
qualified staff that would monitor the ambient air as well as stack emission quality toensure that the pollutants level is maintained always within the permissible levels.
It is proposed to invest about Rs. 145.97 crores on pollution control, treatment and
monitoring systems for proposed power plant. In addition to this, a recurring cost of Rs.
12.55 crores will be spent annually.
Risk Assessment and Disaster Management
Risks likely to pose a risk to humans, environment or property associated with various
activities are addressed in this report. Such activities include transport, storage; handling
and usage of fuels (fuels & LDO). Precautionary measures to be taken for preventing any
hazards due to these materials are proposed in the report. All equipment vulnerable to
explosion or fire would be designed to relevant IS codes and statutory regulations.
Specific precautions should be taken with respect to hazardous chemicals and regular
mock drills should be carried out to enact accident scenarios with reports sent to the top
management. Suitable fire protection system comprising hydrants and spray systems are
provided for fire protection. Fire extinguishers should be tested periodically and to always
be kept in operational mode.
Surrounding population (including all strata of society) should be made aware of safety
precautions to be taken in case of any mishap in plant. On-site disaster management and
off-site emergency plans, commands communication and controls will be established and
maintained.
Adequate provisions like emergency response, response organization, response plan,
material safety data sheet, command & control, capabilities, transportation, medical
facilities, mitigation measures, training, education, public awareness emergency plan
review etc to control any disaster situation will be made available

Air Pollution Management
Fugitive and stack emissions from the power plant will contribute to increase inconcentrations of particulate matter and gaseous pollutants. The mitigation measures
proposed in the plant are:
Installation of ESP of >99.9% efficiency to limit the PM concentrations below 50
mg/Nm3;
Provision of 220 m high stack for wider dispersion of gaseous emissions;
Dust extraction system will be provided at transfer points; Provision of water sprinkling system at material handling and storage yard;
Asphalting of the roads within the plant area; and
Development of greenbelt around the plant to arrest the fugitive emissions.
Water Pollution Management
The effluents generated from the power plant during operations will be collected stream-
wise for various treatments as envisaged in the wastewater treatment scheme. The
wastewater recovery, as practiced, will considerably reduce the impact on the surface
water quality. The recovered wastewaters collected in a central monitoring basin will be
reused with in plant premises and greenbelt/irrigation. The measures proposed to
minimise the impacts are:
Provision of sewage treatment plant to treat domestic sewage from plant and
township;
Utilization of treated domestic wastewater for greenbelt development;
HDPE liners will be provided to the ash pond in order to arrest any seepage of ash
pond water into groundwater;
Provision of separate storm water system to collect and store run-off water duringrainy season and utilization of the same in the process to reduce the water
requirement;
Suitable rainwater harvesting structures to be constructed.

Provision of earplugs to the workers working in high noise level area.
Solid Waste Management
The main solid waste from the proposed power plant will be ash (fly ash and bottom
ash). Considering the expected Lignite quality, about 0.7 MTPA of ash will be generated
from the power plant proposed unit. Out of this, the bottom ash will be about 20% of the
total ash generated i.e. 0.14 MTPA and the fly ash will be remaining 80% of the total ash
generated i.e. about 0.56 MTPA.
It is proposed to utilize 100% of the fly ash generated from the project for cement and
brick manufacturing at existing and proposed cement plants in the vicinity from 4th year
of operations. During emergency the ash will be disposed off safely in ash pond area to
avoid environmental hazards. All efforts will be made to utilize bottom ash for various
purposes. Unused bottom ash will be disposed off in the ash pond proposed within the
plant complex. To control fugitive dust emission from the ash pond area water sprinkling
would be done. After the ash pond is abandoned, its area will be reclaimed through tree
plantation.
CSR ActivitiesBTPCL will implement a Community Development Plan in phased manner through a
dedicated cell, starting from the construction phase onwards. It is proposed to invest a
good amount for various community development activities in the region. BTPCL will
implement the same with the help of NGOs/Government Organizations in the region
Conclusion
The proposed power plant has certain level of marginal impacts on the local environment.
However, with the implementation of the proposed pollution control and environment
management measures, even the minor impacts anticipated due to construction and

1.3 JUSTIFICATION OF THE PROJECTIn order to meet the demand and supply gap in power generation, Government of India
(GOI) initiated promotional measures for private participation in power generating sector.
The enactment of Electricity Act 2003 has created a liberal framework for power
development and a competitive environment to facilitate private investment. The main
features of the Act are:
De-licensed generation except hydroelectric and captive power plants free from
control;
Rural areas: Stand alone generation and distribution de-licensed;
Mandates creation of regulatory commissions;
Open access in transmission from outset;
Open access in distribution to be followed by SERCs in phases; Gradual phasing out of cross subsidies; and
Trading distinct activity permitted with licensing.
GOI seeks to bring about a qualitative transformation of electricity sector through a new
paradigm. The power sector will be made healthy and would be able to attract funds from
private companies by creating a liberal framework of development by distancing
government from regulations.
1.3.1 Power Situation in IndiaThe demand of electricity has been steadily increasing in the country due to rapid
industrialization and large-scale use of electricity for irrigation, domestic and commercial
purposes. Though there has been substantial growth in power sector infrastructure in
India, the power supply position is still characterized by shortages, both in terms of
demand met during peak periods and the overall energy supply. The actual power supply
position and generation capacity in India is given in Table 1.2 and Table 1.3
respectively.

From the above tables it may be noted that there has been a continuous power shortage
in all regions with maximum deficit in northern and western regions. The gap between
demand and supply at the all India level has increased over the last few years resulting in
overall power supply deficit. In recent times, core sector industries have failed to achieve
the target production rate due to shortage of inputs, particularly electrical power, which is
one of main factors inhibiting the attainment of production targets.
Government of India has targeted sustained growth, which cannot be achieved without
higher rate of growth of core sectors. Keeping the present scenario of shortages in

1.3.3 Twelfth Plan Perspective (2012-2017)The working group on power have considered that during the 12 plan period, assuming a
GDP growth rate of 9% per annum and elasticity of 0.8 as compared to 1.0, during 11th
plan mainly due to adoption of energy efficient technologies and other energy
conservation and demand side management measures being taken up during the 11th
plan, electricity demand is likely to grow @ 7.2% per annum. Accordingly the energy

The actual growth in industrial, agricultural and domestic demand will establish that there
is an appreciable shortfall in the installed capacity, demand and energy availability as on
date. This shortfall will continue even after the commissioning of the proposed power
plants in the State and in the Northern region. In Rajasthan, due to increasing
industrialization, the demand for power will be ever increasing. All major industries in the
State resort to captive power generation to meet their demand for uninterrupted power in
spite of costs being high.
Considering the above scenario of power requirement on all-India basis and the persisting
power shortage in Western and Northern region, the proposed 250 MW capacity Thermal
Power Project is well justified and will help bridge the demand supply gap in the country
in general and in Northern and Western region in particular.

1.5 ADMINISTRATIVE AND LEGISLATIVE BACKGROUND1.5.1 Procedure for Environment ClearanceEnvironmental clearance of any new project or expansion of existing projects is now done
as per the new notification of the Ministry of Environment and Forest (MoEF), Govt. of
India dated 14th September 2006. The new notification requires prior environmental
clearance of all projects from competent central govt. or state govt. authorities, as may
be the case. The projects are now classified into Category A or Category B projects based
on spatial extent of potential impacts on human health, natural and man-made resources.
The Category A projects require prior clearance by the MoEF, Govt. of India while the
Category B projects have to get clearance from the State level Environment Impact
Assessment Authority (SEIAA), constituted by the Central Government for this purpose.
The environment clearance procedure for new projects will require maximum of four
stages all of which may not be applicable to all the projects.
Stage 1-Screening: It refers to the definite assignment of environmental category to
projects or activities where the same is not completely specified. The projects are
categorized as A, B1 and B2. Category A projects are scrutinized and cleared through
the EAC at MoEF, Govt. of India. In case of Category 'B projects scrutiny of application at
State level to categorize project in 'B1 or B2 is done. The B2 projects do not require

Stage 3-Public Consultation: It refers to the process by which concern of local people
and other stakeholders are ascertained and their views taken regarding the project. ThePublic Consultation takes part in two steps: Public hearing and written responses. The
public hearing of the present project will take place as per the stipulations of Rajasthan
Pollution Control Board.
Stage 4-Appraisal: This refers to detailed scrutiny of the application, EIA report and
related studies to make categorical recommendations to the regulatory authority.Environment Clearance is accorded to the project after SEAC is satisfied with all
environment aspects of the project.
1.6 ENVIRONMENT LEGISLATIONSThe environmental regulations, legislations and policy guidelines and control that may
impact the project are the responsibility of a variety of Government agencies. The
principal environmental regulatory agency in India is the Ministry of Environment and
Forest (MoEF), Govt. of India. MoEF formulates environmental policies and also accords
environmental clearance for different category projects.
Many State and Central legislations have a bearing on environment but laws on
environment protection have been notified recently. These legal enactments can be
broadly classified in the terms of focus areas, viz. pollution, natural resources and
linkages between pollution and natural resources. The important environment legislations
related to environmental clearance for new projects are briefly described in the Table
1.8.
The MoEF is the nodal agency to set up policy and standards for the protection of
environment, along with Central Pollution Control Board (CPCB). This includes air, noise,
water and hazardous waste standards. The relevant standards for coal-based Power
Plants, which are of significance to the project, are given inAnnexure III.
