1.0 Background

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 village, Akaltara Tehsil, Janjgir- Champa District in Chhattisgarh State. 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 up to 31st December, 2017 vide MoEF’s letter No. J-13012/44/2008-IA.II (T) dated 23.09.2015.

Chhattisgarh Environment Conservation Board (CECB) has granted “Consent for Establishment” for 3600 MW power plant of KMPCL and also granted “Consent to operate” for two units on 28.02.2013 and 15.04.2014.

As on today, KMPCL has commissioned two units of 600 MW capacity each on 14.08.2013 and 26.08.2014 and source of coal is South Eastern Coalfields Limited, a subsidiary of Coal India Limited. The generated power is being supplied to Telangana, Andhra Pradesh, Tamil Nadu and Uttar Pradesh States through Long Term Power Purchase Agreements.

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

Vimta Labs Limited, Hyderabad 4

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.

 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. Vimta Labs Limited, Hyderabad 5

 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.

Vimta Labs Limited, Hyderabad 6

 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.

Vimta Labs Limited, Hyderabad 7

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.

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.

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.

The observation from predictions reveal that the maximum incremental 3 concentration of PM10, PM2.5, CO and NOx are in the range of 11.1 to 48.0 µg/m , 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.

8.0 Environment Management Plan

8.1 Mitigation measures for controling vehicle borne dust emissions

 All trucks shall be covered with tarpaulin and environmentally compliant;  Adequate greenbelt shall be augmented in consultation with the competent authorities;  Regular maintenance and servicing of trucks shall be carried out;  Idling of the trucks and dumpers on the access roads shall be restricted;  Regular water sprinkling shall be done with the maximum possible extent; and  Road maintenance and repairing of the roads.

8.2 Noise Mitigation Measures

 The roads are bituminous and the noise will be absorbed;  Open-garded asphalt pavement matériel for tire noise réduction;  Speed limit reduction in certain neighbourhoods;  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.

Vimta Labs Limited, Hyderabad 23

 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.

 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.

Vimta Labs Limited, Hyderabad 24

 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.
