1.3 Technology and Process Description
Steam Generator Units
The basic plant design considers unitized concept except for ancillary plants, as is
the practice. Judicious provisions have been considered while deciding the
margins in various system and system components and interchangeability of
equipment/system. State-of-the-art technology has been considered for design of
the proposed station. To achieve efficiency without sacrificing availability, the
choice of steam parameters has been limited to sub-critical range.
The parameters of the main plant and equipment are presented in Table-3.

2.0 Need of Change of Coal Source
During development stage, KMPCL had firm coal linkage from Morga-II Coal
block of Gujarat Mineral Development Corporation (GMDC) Limited (for first
three Units) and Gare Pelma Sector-III coal block of Goa Industrial
Development Corporation (GIDC) (for last three Units). Fuel Supply
Agreements (FSAs) were executed with both GMDC & GIDC.
The coal requirement for the power plant is about 14.14 Million Tonnes Per
Annum (MTPA). Coal was to be transported from coal mines to the site
through rail.
Due to delay in development of Morga-II coal block, KMPCL approached
Standing Linkage Committee (Long Term) (SLC (LT)) and SLC (LT) authorized
issuance of Letter of Assurance (LOA) by Coal India Limited on tapering basis
on 12.11.2008. On 11.06.2009, South Eastern Coalfields Limited, a subsidiary
of Coal India Limited, issued a Letter of Assurance (LOA) for 74,91,000 (7.49
MTPA) tonnes per annum to meet the coal requirement of 1800 MW (Units 1
to 3) out of 3600 MW capacity at the power plant.
Later, MOEF was approached for the amendment in EC to get the source of
coal changed from GMDC’s Coal Block to South Eastern Coalfields Limited until
the coal block of GMDC becomes operational. On 24.01.2012, MoEF issued the
amended EC including coal linkage from South Eastern Coalfields Limited as a
source of coal for three units.
Later, in accordance with CCEA decision, Government of India through
Presidential Directive dated 17.07.2013 mandated Coal India Limited to sign
Fuel Supply Agreements with Power developers including Tapering Linkage
holders, identified by Ministry of Power for supply of the domestic coal

quantity of 65%, 65%, 67% and 75% of Annual Contracted Quantity for the
remaining four years of the 12th Plan (i.e. from 2013-14 upto 2016-17). It
was also directed that to meet its balance FSA obligations, CIL may import
coal and supply the same to willing power plants on cost plus basis or Power
plants may also directly import coal themselves, if they so opt.
Further, New Coal Distribution Policy issued by Ministry of Coal, Government
of India was amended on 26.07.2013 to outline the above directives for
implementation.
On 19.03.2014, Fuel Supply Agreement was signed between KMPCL and
South Eastern Coalfields Limited to supply 49,94,000 tonnes per annum to
meet the requirement of two units of 600 MW capacity each (1200 MW).
Through this FSA, SECL committed to supply 3.2461 MTPA (65% of Annual
Contracted Quantity) in 2014-15, 3.34598 MTPA (67% of Annual Contracted
Quantity) in 2015-16 and 3.7455 MTPA (75% of Annual Contracted Quantity)
in 2016-17 to meet the requirement of two units.
Similarly for third unit, Fuel Supply Agreement was signed between Eastern
Coalfields Limited and KMPCL on 12.08.2014 for 1.763 MTPA.
However, Hon’ble Supreme Court, vide its orders dated 25.08.2014 and
24.09.2014 has cancelled allocation of all the coal blocks which also included
Morga II and Gare Pelma Sector III Coal Blocks that were linked to the KMPCL
project.
Pursuant to the cancellation of allotment of coal blocks by Hon’ble Supreme
Court, Ministry of Coal, on 30.06.2015, cancelled the tapering linkage granted
to KMPCL and directed CIL (SECL) to continue coal supplies to the Power Plant
under MOU mechanism till 31.03.2016 or till formulation of new policy by
Government of India, whichever is earlier.
Presently, SECL is continuing the coal supplies to 2 Units under an MOU dated
13.07.2015 to the extent of 67% of the Annual Contracted Quantity.
To meet the balance quantity of coal in line with Presidential Directive and
New Coal Distribution Policy and considering the inferior quality of coal
supplied by SECL (which is lesser than design specification of boiler of power
plant), it is now necessary to procure coal of higher GCV coal including
imported coal (available through Rail mode), in addition to Domestic Open
Market Coal (available through Road e Mode), to address the situation that
has arisen out of implementation of the Presidential Directive by Coal India
Limited. Blending of SECL’s coal and high GCV Coal from Imported and Open
Market coal sources will match with the boiler requirements and also meet the
balance coal requirement of the KMPCL units.
At present, to meet the balance amount of coal for the two units, KMPCL is
also sourcing coal from SECL though forward e-auction process, which is
supplied by SECL only by Road mode.
Environmental Management Plan for Change of Procurement mode from
Linkage Coal to Forward E-Auction Coal and Permission to Transport of
Coal from SECL Coal Mine Area to Power Plant Site, Nariyara Through Railway and Road mode in Operation of 3600 MW Coal Based Power Plant at Nariyara, Akaltara Tehsil, Janjgir-Champa District, Chhattisgarh State
Vimta Labs Limited, Hyderabad 6
To meet the requirement of coal for the balance four units, KMPCL is pursuing
with Ministry Coal and Ministry of Power to provide long-term coal linkages
under the new policy mechanism under consideration of the Ministry of Coal.
The New Coal Distribution policy presently in vogue mandates CIL to meet
100% of the coal requirement of the Power Sector from Domestic Coal
sources.
Till November 2015, Railway Logistics Plan allowed only Western Ports to
procure imported coal for the Power Plants situated in the state of
Chhattisgarh. However recently on 13.11.2015 and 07.12.2015, Railway
Board, Ministry of Railways approved the procurement of imported coal by
KMPCL from Eastern Ports (through Nagpur route) namely Gangavaram,
Vizag, Kakinada and Krishnapatnam ports.
Rail distance from Kandla Port to KMPCL Power Plant is 1675 Km, which
amounted to Rs. 3277 per tonne transportation cost. After approval of Eastern
Port through Nagpur route, the distance has come down to 1467 KM which
has reduced the transportation cost to Rs. 2865 per tonne and coupled with
the fall in prices of imported coal, it is now financially viable to procure
imported coal. Now on the basis of approval provided by the Railway Board,
KMPCL is intending to import coal from eastern ports.
Hence, considering all above recent developments, to meet the balance coal
requirement till CIL supplies 100% of coal from Domestic Sources, KMPCL is
planning to procure coal through forward e-auction by Rail / Road mode, local
vendors supplying SECL/CIL coal by Road mode and Imported coal from
different countries including Australia, South Africa, USA, etc as temporary
arrangement.
3.0 Transportation of Coal SECL, Korba area to Plant site
During development stage, KMPCL had firm coal linkage from Morga II Coal
block of Gujarat Mineral Development Corporation (GMDC) Limited (for first
three Units) and Gare Pelma Sector-III coal block of Goa Industrial
Development Corporation (GIDC) (for last three Units). The coal requirement
for the power plant is about 14.14 Million Tonnes Per Annum (MTPA). Coal
was to be transported from coal mines to the site through rail. For this
purpose, a dedicated Railway corridor is envisaged to cater the needs of
KMPCL plant from Morga-II and Garepelma coal block area. A Detailed techno-
feasibility and route alignment studies also have been carried out. In this
connection, MOEF specified a condition that 4th year onwards the entire coal
shall be transported through rail mode till that road transportation of coal is
permitted. Due to cancellation of allotment of coal blocks by Hon’ble Supreme
Court, Ministry of Coal, on 30.06.2015, cancelled the tapering linkage granted
to KMPCL and directed CIL (SECL) to continue coal supplies to the Power Plant
under MOU mechanism till 31.03.2016 or till formulation of new policy by
Government of India, whichever is earlier.

On 19.03.2014, Fuel Supply Agreement was signed between KMPCL and
South Eastern Coalfields Limited to supply 49,94,000 tonnes per annum to
meet the requirement of two units of 600 MW capacity each (1200 MW).
Through this FSA, SECL committed to supply 3.2461 MTPA (65% of Annual
Contracted Quantity) in 2014-15, 3.34598 MTPA (67% of Annual Contracted
Quantity) in 2015-16 and 3.7455 MTPA (75% of Annual Contracted Quantity)
in 2016-17 to meet the requirement of two units. As on today, 3.34 MTPA of
coal is being supplied from SECL, Korba region. Out of which 60% of coal is
being transported from Korba region (Kusumunda, Dipka and Gevra area) to
plant site through railway wagons and balance amount has been transported
through road mode. KMPCL requires about 14.02 MTPA of coal in operation of
3600 MW thermal power, the details of coal requirement and mode of
transport of coal from mines area to plant site is presented in Table-4.

3.1 Impact on Traffic Load due to Coal Transportation
Impact of Coal Transportation on Roads and Surroundings
Project traffic impacts have been analyzed in terms of generally acceptable
procedures for trip generation, trip distribution, and traffic assignment.
3.1.1 Impact of off-Site Traffic on Air Quality
On account of various associated activities, there will be increased vehicular
traffic on connecting roads. Generation of particulate emissions is therefore, of
primary concern.
Environmental Management Plan for Change of Procurement mode from
Linkage Coal to Forward E-Auction Coal and Permission to Transport of
Coal from SECL Coal Mine Area to Power Plant Site, Nariyara Through Railway and Road mode in Operation of 3600 MW Coal Based Power Plant at Nariyara, Akaltara Tehsil, Janjgir-Champa District, Chhattisgarh State
Vimta Labs Limited, Hyderabad 8
The extent of these impacts, at any given time depends upon
The rate of vehicular emission within a given stretch of the road; and
The prevailing meteorological conditions.
The impacts have strong temporal dependence as both of these factors vary with
time and would have diurnal, seasonal as well as long term components. The
modelling stimulations has been computed based on traffic routes from nearby
mine/washery to power plant. Out of 7.636 MTPA, 3.818 MTPA will be transported
through road network. The coal will be transported from Korba area to plant by
road through 28 T capacity trucks. Based on the transportation by road, the total
number of trucks required to cater need of power plant will be about 748 (to &
fro) per day. The coal transportation routes are shown below.
3.1.2 Coal Source and Transportation Route
M/s. KMPCL proposes to source coal from various mines i.e Dipka, Gevra,
Manikpur and Kusumunda opencast mines are major sources of coal in Korba
region. 30% of linkage coal of KMPCL has been sourcing from Korba area of
SECL. From KJSL washery, Dipka, Gevra, Kusaumuda and Manikpur opencast
mines are directly connected to dedicated road which joins village Hardi Bazar
area. The road width is about 3.7 to 4.0 m from the median excluding 2.0 m
shoulders on either side of the road. The road connecting to Chhal mines via
jangir champa and Kharsia is 3.7 to 10.0 meters width with 2.0 meters of
shoulder on either side.
For model computations, Right of Way (ROW) of 4.0 m to 10 m excluding 2.0 m
shoulders on either side of the road has been considered for perusal of violations
of standards and accordingly receptor locations have been chosen to account for
its location with respect to edge of ROW.
The mine details along with distance are presented in below Table-5. Coal
transportation route is shown in Figure-2.

4.0 Ambient Air Quality
The ambient air quality with respect to the study zone around the transportation
route forms the baseline information. The various sources of air pollution in the
region are industrial, traffic, urban and rural activities. This will also be useful for
assessing the conformity to standards of the ambient air quality during vehicle
movements along the transportation route. The study area represents mostly rural
and industrial environment.
Ambient Air Quality Monitoring (AAQM) stations were set up at 17 locations.
Table-6 gives the details of environmental setting around each monitoring station.
Air quality monitoring has been carried out for two consequent days starting from
04-04-2017 to 18-04-2017 at selected locations along the transportation route.
The location of the selected stations with reference to the plant boundary is given
in the same table and shown in Figure-3.

4.1.2 Conclusions
The results of the monitored data indicate that the ambient air quality of the
region in general is conformity with respect to norms of National Ambient Air
Quality standards of CPCB, at all locations monitored.
5.0 Impact on Air Quality due to Coal Transportation
5.1 Details of Mathematical Modeling
For prediction of maximum Ground Level Concentrations (GLC’s), the air
dispersion modeling software (AERMOD version 7.1.0) line source was used.
AERMOD is steady state advanced Gaussian plume model that simulates air
quality and deposition fields upto 50 km radius. AERMOD is approved by USEPA
and is widely used software. It is an advanced version of Industrial Source
Complex (ISCST3) model, utilizes similar input and output structure to ISCST3
sharing many of the same features, as well as offering additional features. The
model is applicable to rural and urban areas, flat and complex terrain, surface and
elevated releases and multiple sources including point, area, flare, line and
volume sources.
Dispersion modeling using AERMOD requires hourly meteorological data. Site
specific data is used for executing modeling studies. The site specific
meteorological data is processed using AERMET processor.
5.2 Model Input Data
The predictions of traffic volume incremental concentrations of CO, NOX, PM10 and
PM2.5 due to additional traffic assumed are estimated based on site specific
meteorological conditions and line source. The line source is taken based on
nearest road transportation route from the nearby coal mines and washeries to
plant boundary. The emission rates as inputs to the line source model are
calculated based on “Emission factor development for Indian Vehicles”, a project
executed by Automative Research Association of India, Pune, 2008. The inputs
used for modeling area given in Table-8.

Emissions from Road Dust
Particulate emissions occur whenever vehicles travel over a paved surface such as
a road or parking lot. Particulate emissions from paved roads are due to direct
emissions from vehicles in the form of exhaust, brake wear and tire wear
emissions and re-suspension of loose material on the road surface. In general
terms, re-suspended particulate emissions from paved roads originate from, and
result in the depletion of, the loose material present on the surface (i.e., the
surface loading). In turn, that surface loading is continuously replenished by other
sources. At industrial sites, surface loading is replenished by spillage of material
and track out from unpaved roads and staging areas.
Dust emissions from paved roads have been found to vary with what is termed
the "silt loading" present on the road surface. In addition, the average weight and
speed of vehicles travelling the road influence road dust emissions.
Paved Road Emission Factors
The quantity of particulate emissions from re-suspension of loose material on the
road surface due to vehicle travel on a dry paved road may be estimated using
the following empirical expression:
E = k (sL)0.91 (W)1.02
Where:
E = Particulate emission factor (having units matching the units of k);
sL = Road surface silt loading (grams per square meter) (g/m2);
k = Particle size multiplier for particle size range; and
W = Average weight (tons) of the vehicles travelling the road.

1.7 to 16.6 µg/m3, 1.2 to 7.1 µg/m3 and 1.3 to 11.0 µg/m3 respectively likely to
occur within 10 m from the centre of the road. The CO and NOx concentrations
are likely to be very low when compared with NAAQS for CO (4000 µg/m3) and
WHO standard of 400 µg/m3 for hourly average for NOx.
5.4 Impact on Roadside Habitation Due to Coal Transport
The predicted 24 hourly resultant maximum concentrations of CO, NOX, PM10 and
PM2.5 were observed to be occurring at road side occurring within 10 m from the
centre of the road. However, these concentrations will be less at nearby
habitations. The resultant concentrations at nearby villages/settlements are
presented in Table-10.

From the above table, it can be observed that the resultant concentrations of
PM10 and PM2.5, NOX and CO, were found to be within the NAAQ standards.
Further, above predictions represents worst case scenarios representing
longer road transport route option. However, in actual scenario the coal
transportation distance will be lesser than the worst case transportation
route (longer route) considered.
6.0 Adequacy of Existing Road Network in Study Area
The traffic contribution due to road network, will thus is the ‘to and fro’ movement
of 748 vehicles per day, which is equivalent to 2244 PCU per day wherein the
maximum carrying capacity of 7 m wide road is of 15,000 PCU/day. The estimated
peak traffic in terms of PCUs, when compared to the stipulated standards by IRC for
traffic capacity of the roads and it can be observed that the existing road network is
adequate. IRC recommendations are provided in Table-11.

6.1 Details of Road and Project Induced Traffic
Traffic study was conducted during 1st week of April 2017. The existing traffic
mainly includes trucks carrying coal from surrounding coal blocks of Dipka,
Kusumunda, Manikpur and Gevra mine area directly to KMPCL via National
Highway 200 and NH-149 B also KJSL coal washery which near village Dhatura
and Hind coal washery near Balooda bazar further transport to Akaltara and plant
site to deliver to end user.
Coal blocks of Chhal, Baroud and Jampali opencast mines are also the major
source of coal to the nearby industries including KMPCL in the region. Coal from
these mines transported to KMPCL via Sakti, Champa and Janjgir.
Trolley truck of 28 Tonnes and tipper of 25 or 15 tonnes capacity are currently
being deployed by various transporters. The details of road transport route from
different mines with road width is presented in Table-5.
The traffic study was conducted to know the prevailing traffic volumes on the roads
in the area. Impact due to transport of raw material on the air quality has been
carried out in. To assess the prevailing traffic volumes on the roads, a survey was
conducted during normal working day of the week by avoiding local holidays or
abnormal situations to reflect the true picture of the traffic density. The traffic flow
was monitored at Nariyara village which is connecting to National Highway-200,
Tarod village, Akaltara and near Amartala village. Traffic survey locations are given
in Figure-4.

6.2.2 Impact of proposed Traffic on Road Adequacy
With present level of traffic and proposed traffic due to the project during
operational phase has been estimated by comparison with the recommendations
stipulated by the Indian Road Congress (IRC). The IRC recommendations on
traffic capacity are presented in Table-9.
The existing road is a two lane road as such as per IRC recommendation is
adequate for a maximum of 15,000 PCUs/day. The projected vehicles count in
PUCs is well with the IRC recommendations.
7.0 Impact on Noise Quality
For KMPCL power project, the required coal will be sourced from nearby coal mines
and washeries. Noise pollution in the region is mainly due to movement of vehicles
including vehicles movement of other coal consumers.
A preliminary reconnaissance survey was undertaken to identify the villages /
habitations on road segment of coal transportation route. The monitoring was
conducted at nearby identified roadside habitations on 7th April 2017 for
determination of ambient noise levels.
The noise levels at each location were recorded for 24 hours. The environment

Banning truck operations at certain urban streets;
Enforcing sufficient right of way distances;
Establishing greenbelt buffer zones to reduce noise levels at receptor
locations;
Unwanted honking shall be restricted.
8.3 Road Safety
Road accidents can occur due to various reasons and are not caused intentionally.
Accidents result due to a combination of different factors such as external factors
i.e weather and road conditions, road users and the condition of the vehicle.
These factors never act as isolated entities. Most common are the mistakes of the
driver followed by bad street conditions, mistakes of a pedestrian as well as
technical and maintenance defects. Accident prevention measures will be
implemented as followed:
Safe Traffic System Design and Accident Prevention Measures
The main technical defects causing accidents are detected on tyres, lights,
brakes and the steering. High-quality rubber will be used to the grip as well as
the braking of a vehicle to lower accident rates;
Median barriers will be arranged with help of state government to prevent
overtaking and to eliminate head-on crashes;
Better highlighting of hazards through road lighting at residential areas and at
other major junctions and roundabouts;
Advisory speed limits at sharp bends.

Measures to slow the traffic eg. Decreasing of speed at selected places
(eg. Settlements, schools, markets etc.). Residential access roads are designed
to achieve very low speeds, normally around 30 km/h;
Improving signs and markings at High-risk sites.
The fitness tests of motor vehicles will be carried out regularly to assess the
vehicle condition;
Drunken driving is significant and widespread factor in road crashes,
effective measures shall be taken to reduce alcohol influenced crashes and
injuries;
Road safety awareness training will be given to truck drivers and residents of
nearby villages.
Improvements in road signage and pavement markings and attention to road
accident clack spots.
9.0 Conclusion
KMPCL presently sourcing coal from SECL though forward e-auction process to
meet the balance amount of coal for the two units, which is supplied by SECL
only by Road mode.
To meet the requirement of coal for the balance four units, KMPCL is pursuing
with Ministry Coal and Ministry of Power to provide long-term coal linkages
under the new policy mechanism under consideration of the Ministry of Coal.
Railway Board, Ministry of Railways approved the procurement of imported
coal by KMPCL from Eastern Ports (through Nagpur route) namely
Gangavaram, Vizag, Kakinada and Krishnapatnam ports. Now on the basis of
approval provided by the Railway Board, KMPCL is intending to import coal
from eastern ports.
Hence, considering all above recent developments, to meet the balance coal
requirement till CIL supplies 100% of coal from Domestic Sources, KMPCL is
planning to procure coal through forward e-auction by Rail / Road mode, local
vendors supplying SECL/CIL coal by road mode and Imported coal from
different countries including Australia, South Africa, USA, etc as temporary
arrangement.
The traffic modelling stimulations has been computed for AAQ predictions based
on traffic routes from nearby mines/washery to power plant. Out of 7.636
MTPA, 3.818 MTPA will be transported through road network. The coal will be
transported from Korba area to plant by road through 28 T capacity trucks.
Based on the transportation by road, the total number of trucks required to
cater need of power plant will be about 748 (to & fro) per day.

The observation from predictions reveal that the maximum incremental
concentration of PM10, PM2.5, CO and NOx are in the range of 11.1 to 48.0
µg/m3, 1.7 to 16.6 µg/m3, 1.2 to 7.1 µg/m3 and 1.3 to 11.0 µg/m3
respectively likely to occur within 10-m from the centre of the road. The CO
and NOx concentrations are likely to be very low when compared with NAAQS
for CO (4000 µg/m3) and WHO standard of 400 µg/m3 for hourly average for
NOx.
Due to additional traffic there will be slight increase in particulate matter levels
along the road. The maximum incremental particulate matter concentrations
likely to occur at 10 m from the centre of the road. The resultant
concentrations of PM10 and PM2.5, NOX and CO, were found to be within the
NAAQ standards. Further, above predictions represents worst case scenarios
representing longer road transport route option. However, in actual scenario
the coal transportation distance will be lesser than the worst case
transportation route (longer route) considered.
Suitable dust control measures will be taken to arrest/dispersion of dust
towards nearby habitations. The suitable EMP measures will be implemented
to reduce the impact of road dust.
The traffic study was conducted to know the prevailing traffic volumes on the
roads in the area. Impact due to transport of raw material on the air quality
has been carried out in. The estimated existing peak traffic in terms of PCUs
are compared with the stipulated standards by IRC for traffic capacity of the
existing road network.
Air quality monitoring has been carried out at selected locations along the coal
transportation route. The concentrations of PM10, PM2.5, CO and NOx are in the
range 41.3 to 88.4 g/m3, 25.2 to 52.6 g/m3, 15.9 to 27.9 g/m3 and 430 to
890 g/m3 respectively.
The existing road is a two lane road as such as per IRC recommendation is
adequate for a maximum of 15000 PCUs/day. The projected vehicles count in
PUCs is well with the IRC recommendations.
Noise pollution in the region is mainly due to movement of vehicles including
vehicles movement of other coal consumers. The noise level survey conducted
at selected locations along the transportation route. The noise levels in day and
night time are within the limits prescribed by CPCB.
By implementing EMP measures to control the air pollutants and noise levels
there will be no significant impact will be due to the additional traffic movement
from nearby coal mines to KMPCL.
