Sub: Liftina of coal bv Road Mode.
Dear Sir,
In continuation to our discussions on the above referred subject matter, we would like to
inform that due to the acute paucity of railway wagons the planned despatch through rail mode is not being materialized.
It is therefore necessitated to deliver coal to the units located in the vicinity of mines by
road mode for faster evacuation of coal stocks and usage of additional railway wagons
thus generated, for long distance coal transportations.
As per the logistical analysis, it i s evident that your unit is located equally at about 30-40
Kms from the mines of Gevra, Kusmunda and Manikpur OC. You are therefore advised
to revert to the lifting of your requirement of coal by road mode and place orders
accordingly so that the necessary arrangement for its delively can be initiated.
Yours faithfully,

Sub: Request for Lifting of Linkage coal by existing Rail Mode as per FSA.
Reference: 1. FSA SL NO N117 executed with SECL on dated 19.04.2014 and Addendum # 5
Dt. 31.03.2015.
2. SECL Letter No SECL/BSP/S&M/OPRN/749 DT 17/18.04.2015
Dear Sir,
Kindly refer to your letter cited 2 above. In this regard, we would like to inform you that we wish to
continue to lift our monthly allocated coal quantities by existing rail mode system only, under above
referred FSA. In this regard we write to bring to your kind attention following grounds which are
relevant in this matter :
1. We have done huge investments for development of a giant railway infrastructure at our
plant. The total track length of our railway infrastructure is around 48 Kms, out of which
there are 04 tracks inside the plant for the reception of coal rakes and also it houses two
wagon tipplers and two track hoppers as well, enabling us to handle coal rakes considering
our unit size of 6x600 MW. With this decision of SECL, all our efforts and investments for
setting up such massive infrastructure will go for a toss and will be a huge setback for us. In
addition, our state of the art infrastructure and unloading facility further facilitates SECL for
faster turnaround of rakes and thus directly helps your cause of increasing
materialisation/despatches from mines.
Our Plant is situated a t about 90 kms from the mines of Dipka, Gevra and Manikpur (Korba
Area) and 140 kms from Chal and Baroud (Raigarh Area). We have FSA with SECL
(KorbaIRaigarh) for two units i.e. 1200 MW .The monthly FSA allotted quantity presently is
3 lakhs tonnes per month for 2 units or 10000 MT /Day ie. around 500-600 trucks /day. The
daily coal consumption for 2 units is about 17000 MT . Linkage coal therefore, is about 60%
of our daily coal requirement. It is evident from these facts that , as anticipated by you in
your letter, our plant is at a larger distance than 30 -40 km envisaged and hence road mode
deliveries are not advisable from Logistics point of views of movement of so many vehicles
(outside plant and inside plant) and unloading infrastructure in our plant.

3. As per plant design, we are not equipped to handle road movement for such bulk quantities
and it is a herculean task to sustain uninterrupted generation. Handling around 600+ trucks
at the plant is impossible and not feasible for a unit size like ours.
4. Our plant is not designed to handle coal supply by road, due to technical restrictions and
plant design. Coal from the rake is directly unloaded a t hopper, crushed to (-30MM) size and
fed to the boiler (through mills) directly for consumption or stacked a t Unloading Yard.
Unlike this, in case of Road mode, coal shall be unloaded at stacking yard and it cannot be
crushed to (-30MM) size and fed to the boiler. Plant i s not equipped with separate crusher
or feeding unit for road mode. Further, we need to re-handle coal in plant to feed into
Hoppers for which new road infrastructure shall be needed in plant. This new arrangement
of road movement from coal yard to Hopper, by technical standards, for 600 trucks
movement within plant shall be UNSAFE practise, prone to accidents in plant. Due to the
technical design Constraints, it is impossible to handle. linkage raw coal by trucks. Any such
modifications in the plant layout are not at all feasible or possible for us at this juncture not
advisable from Safety point of view.
5. It i s pertinent to note that our rail distance from SECL siding is 98 KMs and coal requirements
are primarily being catered through BOBRN. We are maintaining the minimum rake
unloading timing at our end, restricting the same a t around 45 minutes (one of the Best
among other customers of SECLISECR). Apart from this, BOBRN wagons which are only kept
by the railways for consumers with Bottom Hopper facilities will remain unutilised and
resulting into non-performance of government assets. Due to shorter distance, the
turnaround time and availability of rakes increases by serving customers nearby by rail,
rather than serving those at far off distances, where i t will take more time to receive the
rakes back. BOBRN helps to maximise'loading and reducing the rolling stock at SECL Mines
and they are preferred for such short distance movement only. This is a win - win situation
for Railways, SECL and Customer like us. Therefore, this condition proposed is discriminatory
in nature and should not be prescribed by SECL, being a public authority only for power
plants situated near the coal mines of SECL. Any decision proposed to be implemented by
SECL must be equal on all grounds for all the coal consumers of SECL.
6. As regards paucity of wagons referred in your letter, we had also taken up the matter with
DRM/CFTM/SECR who has advised us that there is no wagon shortage, especially for
BOBRN wagons, utilised for short- lead & closed - circuit traffic on SECR. The Railway
management have also conveyed the State Govt's concern over the need to avoid large-
scale road -transportation of coal, in public interest, through adaptation of the cost-efficient
& environment-friendly rail option. Moreover, close circuit BOBRN wagons are available
with SECR to clear the entire stock of KMCPL (as confirmed by the DRM (SECR) t o CMD
SECL Bilaspur vide their letter no. P/KMPCL/15, dated 24-04-2015, Letter Attached for
reference).
7. Present road infrastructure and route from mines to our plant is not apt for movement. Such
a huge bulk coal movement by trucks will raise issues from Environment, safety, District
Administration and resistance from the local residents in the vicinity. We have experienced
these issues in past, before commencement of operations of our railway siding, when even
for very limited coal road movement, we had to stop supplies on those grounds. For a fully

running plant like ours, this is not feasible as any stoppage of coal supplies may result in loss
of generation and huge penalties to us due to shortfall in power supplies.
8. Continuous movement of coal shall hamper due t o No-Entry points at Korba, Hardibazar,
Baloda and Akaltara the route which we have t o utilise for linkage coal movement from
08:OO am to 08:OO pm, currently imposed by the local administration in order to ensure
the safety of the enroute villagers/residents. With these restrictions it shall take asking rate
to 1200 truckslday (as movement to be enabled only in 12 hours) which is technically
impossible to handle in our plant as well as exiting State Road networks.
9. The movement of coal by road in place of rail will lead us to a huge revenue loss of approx.
123 CrIAnnum, which can not be passed on to our power consumers under the concluded
PPAs, thereby compromising the commercial viability of our power project.
Therefore considering the plant Infrastructure facilities, Safety, rake availability, Less rail
distance, reduced rolling stock , SECR Consent, hassle free movement, better evacuation of
SECL coal due to close circuit wagons use and power tariff to utilities, linkage movement by
rail is best suited for KMPCL Plant.
Considering all these aspects, we request your goodself to kindly continue our movement of
coal from SECL mines by Rail Mode as per the FSA.

KSK Mahanadi Power Company Limited (KMPCL) (earlier known as Wardha Power
Company Limited) is in the advanced stage of developing a 3600 (6x600) MW
coal based thermal power plant at Nariyara, Akaltara Tehsil, Janjgir-Champa
District in Chhattisgarh. KMPCL is a Special Purpose Vehicle (SPV) promoted by
KSK Energy Ventures Limited (KSK) (a power plant development company) based
at Hyderabad.
In line with the EIA Notification dated 14th September 2006, KSK Mahanadi Power
Company Limited was accorded Environmental Clearance by MoEF vide its letter
no. J 13012/44/08 – IA.II (T) dated 19th Oct, 2009 and the validity of the
Environmental clearance was extended upto 31st December, 2017 vide MoEF’s letter No. J-13012/44/2008-IA.II (T) dated 23.09.2015. Copies enclosed as

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 (ie 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.

Vimta Labs Limited, Hyderabad 4
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.
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
Environment Management Plan of Transportation of coal from Korba Area to KMPCL 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 5
KMPCL from Eastern Ports (through Nagpur route) namely Gangavaram,
Vizag, Kakinada and Krishnapatnam ports. Details are presented in
Annexure-III.
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

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.
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 two traffic routes from plant
to mine. Out of 3.146 MTPA will be transported by route-1 and or Route-II. Both
the routes are shown in Figure-1. 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 616
(370+ 246) to & fro per day.

3.1.2 Details of Mathematical Modeling
For prediction of maximum Ground Level Concentrations (GLC’s), the air dispersion modeling software (AERMOD version 7.1.0) 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.
Model Input Data
The predictions of traffic volume incremental concentrations of CO, NOX and PM
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 mine lease 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-5.

The observation from predictions reveal that the maximum NOx, CO and PM
concentration of 3.49 g/m3 and 2.25 g/m3 and 0.46 g/m3 likely to occur at 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 g/m3) and WHO standard of
400 g/m3 for hourly average for NOx. Hence, it is assumed that the impact on
the present ambient air quality will be negligible due to the additional traffic from
the proposed project.

Details of Road and Project Induced Traffic
Dipka, Gevra and Kusumunda open cast mines are major sources of coal in Korba
region. 30% of linkage coal of KMPCL has been sourcing from Korba area of
SECL. From Dipka, Gevra and Kusaumuda open cast mines are directly connected
to dedicated road which joins village Harda Bazar area.The village road
connecting mine to state high way is 13 meters width with 0.5 meters of
shoulder on either side. For model computations, Right of Way (ROW) of 13.0 m
excluding 0.5 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.
Traffic study was conducted during last week of January 2016. The existing traffic
mainly includes trucks carrying coal from surrounding coal blocks of Dipka,
Kusumunda 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 Akalara and plant site to
deliver to end user. Trolley truck of 28 Tonnes and tipper of 25 or 15 tonnes
capacity are currently being deployed by various transporters. The total traffic
from the project is presented in Table-9. The details of road transport route are

It can be observed that the maximum hourly concentrations for worst case scenario
of 100% traffic volume on one road of CO, NOx and PM due to the additional
traffic load would be about 2.25 g/m3 and 3.49 g/m3 and 0.465 g/m3
respectively, likely to occur at 10 m from the centre of the road. The CO and NOx
concentrations are likely to be very low when compared with the NAAQ standards
for CO (4000 g/m3) and WHO standard of 400 g/m3 for hourly average for NOx.
Hence, it is assessed that the impact on the present ambient air quality will be
negligible due to the additional traffic from the proposed coal transportation from
SECL region to KMPCL area.
Adequacy of Existing Road Network in Study Area
About 616 tucks per day would be required for transportation of coal which is
equivalent to 2772 PCU per day (taking a PCU factor of 4.5 per vehicle). With
present level of traffic and the predicted increase in existing traffic due to the
project, adequacy of road/highway during operational phase of the plant has been
estimated by comparison with the recommendations stipulated by Indian Road
Congress (IRC). The IRC recommendations on traffic capacity are presented in

The existing roads have a width of 13 and 23 mtrs with 0.5 meters shoulder on
either side on road which are adequate for proposed transportation of coal to
KMPCL from SECL region. The estimated peak traffic in terms of PCUs is
compared with the stipulated standards by IRC for traffic capacity of the existing
roads. It can be observed that the existing road network will be well adequate for
the increased traffic.

two unit which are under operation have been already captured in baseline traffic
studies.
Transpiration of coal on road for four units is 3.146 MTPA and rest of coal will be
transported through rail mode from Korba area and also from eastern port such
Krishnapatnam or Gangavaram ports. The total additional truck density for 3.146
MTPA coal transportation will be about 616 trucks (to & fro) considering the truck
capacity of 28 T.
The worst case has been considered to use entire traffic near Chama junction and
Akaltara junction, concentration of C), NoX and Particulates varies 2.19 µg/m3
and 2.25 µg/m3, 3.39 µg/m3 and 3.49 µg/m3 and 0.452 µg/m3 and 0.461 µg/m3.
The resultant concentrations after superimposing on ambient air quality which are
revels that concentration well within the limits of NAAQMS specified by CPCB
It is concluded from the traffic density survey carried out in the study shows that
there will be marginal increase in traffic due to the proposed project activity of
the project. The estimated peak traffic in terms of PCUs, when compared to the
IRC recommendations for traffic capacity of the roads, it can be observed that the
existing road network is adequate to cater the needs of KMPCL plant.
