Compliance:- In order to assessment the Carrying Capacity, assessment of impacts due to mining activities and mitigation plan for Riverine Eco-system of Pench-Kanhan River, a report on the existing scenario comprising of all the mining operations has been prepared and the same is placed below:- .

A. Background:

The proposal for Expansion of Gondegaon OC Coal mine Project from 2.5 MTPA to 3.5 MTPA by M/s. Western Coalfields Limited in an area of 917 ha in village Gondegaon, Tehsil Parseoni, District Nagpur was submitted through online portal of MoEF & CC vide no. IA/MH/CMIN/71601/2017 dated 14-12-2017.

Subsequently, the proposal was considered by the EAC (TP & C) in its 24th meeting held on 11-01- 2018.

As per the specific conditions no viii & ix (quoted below) MoEF & CC has directed to carry out the said study for assessment of carrying capacity & mitigation plan for Riverine Ecosystem:

B. Study Area & Objective:

To prepare detailed report on the impacts of coal mines on the Riverine Ecosystem of Kanhan River. The study area / Area of Interest (AoI) is limited to area around Gondegaon OC Coal Mine and four other Opencast Coal mines viz. Bhanegaon OC, Inder OC, Kamptee OC and Singhori OC within 10 km aerial distance along the river basin.

B (i). Location

Gondegaon OC mine is located in Gondegaon Village, Personi Tehsil, and Nagpur District of Maharashtra State falling between latitudes 1) 21°15'26.52"N 79°10'39.69"E, 2) 21°14'54.22"N 79°11'52.57"E, 3) 21°16'8.60"N 79°12'53.90"E 4) 21°16'40.89"N 79°10'50.00"E and covered under SoI Topo sheet no.55 O/3.

B. (ii) Topography & Drainage of the study area Physiographically, the area shows almost flat topography, except in the south-western part which is represented by small hillocks. The maximum elevation is 300 m while the minimum is 260 m. along the Kanhan River.

Pench River from North East joins the Kanhan River at Ghat Rohana Village adjacent to Gondegaon OC mine.

Pench River in the upstream exhibits dendritic drainage pattern flowing towards south, south-east, south-west and contributing its flow to Kanhan River. In the downstream, Kolar nadi flowing towards East and contributes its flow to Kanhan River. In general the area is sloping towards South, South East & South West directions.

Fig.1: Study Area

B. (iii) Topography & Drainage of Gondegaon OC Mine The surface area is generally undulating with elevations ranging from 260 m to 300 m above MSL. The main drainage is controlled by Southerly flowing Kanhan River along the Western boundary of the mine.

The Kanhan River and its tributary Pench River controls the major drainage.

B. (iv) Geology of the study area: Geologically, the area consists of a numerous lithologies including Archaeans, Gondwana, Lameta, Deccan trap etc. The area represents the type section of the Kamthi Sandstone of the Gondwana Supergroup. The coal reserves in the Gondwanas form economic deposits in the area. The Archaeans forming the base consist mainly of dolomitic marble and quartzites of the Sausar Super Group over which the Gondwana Formations rest unconformably.

The Gondwana formations are mainly represented by the Talchir, Barakar and Kamthi Groups, of which, the Barakar contains good deposits of coal. It is, in turn unconformably overlain by the Deccan trap. The Lameta is not exposed in the study area while alluvium consisting of sand, clay, silt and laterite are well exposed (Fig. 2).

B. (v) Geomorphology:

Nagpur district forms a part of Deccan Plateau having flat topped and terraced features. Eastward and northeastwards the landscape changes due to the change in the underlying rocks. The rocks of Gondwana series present a low rolling topography with a poor soil cover and vegetation. Hill range runs northwards through Katol taluka from Kondhali to Kelod separating the Wardha and Wainganga valleys. The northeastern and east central parts of the district is drained by the Wainganga and its tributaries. The central and western portion is drained by the Wena which is a tributary of Wardha River. Different landform units reported in this area include dissected plateaus, pediplains, pediments, alluvial plains, palaeochannels etc. (Fig. 2). These geomorphic units are grouped on the basis of their origin. The details are as follows: Landforms of Denudational origin – The landforms falling in this category are mainly represented by dissected plateaus, pediplains and pediments. Dissected plateaus are formed in the southwestern region over the Deccan traps. While Pediplains formed over the Gondwana sediments are restricted to the northeastern region. The Archaean metasedimentary terrain is represented by pediments in the map. Landforms of Fluvial origin – The landforms of this origin are identified along the river courses of Kanhan and Kolar. It is represented by alluvium consisting of sand, silt and small amount of gravel. It is formed mainly due to fluvial activity of the Kanhan river system. This fluvial landform constitutes a favorable site for ground water.

Fig 2: Geological Map of the Study Area

Geomorphology of Gondegaon OC: Gondegaon OC is on a topographic high with the slope being towards South East & South directions. The major drainage pattern is dendritic with flow towards East, South East and South. It seems that in areas near Gondegaon OC & adjacent mines the Kanhan & Pench Rivers seems to be effluent in nature. In the pre-mining scenario (2004) the area falling as present day Gondegaon is seen to be a patch of Barren land/waste land with shrub and on the North as alluvial land in the North West. Sand belts have been seen which indicate paleo-channels of the present day rivers. It can thus be deciphered that the crop yield inspire of water availability would be average to poor over such geo-morphological features.

B. (vi) Soil Types:

There are 2 main types of soils found in the study area. The details are as follows:

1) Kali soils: These are black cotton soils which are fine grained clayey in texture and varies in depth from 1 m to 6 m or more and retain moisture.

2) Morand soils: These are predominant in the district. They are black cotton soils with higher percentage of lime than the Kali soils. They are black, grey or light to dark brown in colour, clayey in texture and have a depth of about 1 to 3 m.

5) Kachchar soils: They are mainly found in the banks of Kanhan River and are alluvial soils, loamy in nature and vary in depth from 1 to 3 m.

C. (i) Kanhan River

As per the Central Water Commission, Kanhan River does not fall in their list of major & medium river basins. Kanhan River rises from hills at the southern edge of Satpura range to the north of Damua, a town in Madhya Pradesh and flows in south east direction for about 160 kms before it enters the state of Maharashtra near Raiwari village in Saoner Taluka of district Nagpur.

During its course it passes through Saoner, Nagpur, Kamptee and Mouda Tahsils of Nagpur District covering a distance of about 80 kms, before joining Wainganga as a tributary near Jawahar Nagar Ordnance Factory in district Bhandara District. The Kanhan River is a tributary of Wainganga River with a confluence at Ambhora.

C. (ii) Pench River The Pench River is a tributary of the Kanhan River. It originates in the Chhindwara district of Madhya Pradesh.

Two Dams have been constructed on the river namely Totladoh Dam on the upstream for electric power generation purpose and Pench Dam in the downstream for supplying drinking water to Nagpur city & irrigation purposes. Pench Dam is near the town of Navegaon Khairy and is located in Parseoni Taluka. More than 70% of the drinking water in Nagpur is supplied from these dams.

The Pench right canal supplies water to Nagpur, the Koradi Thermal Power Station, and the Khaparkheda Thermal Power Station, and the rest of the water is use for irrigation in Parseoni taluka, Kalmeshwar, Saoner, Kamthi talukas and rural Nagpur. The Pench left canal irrigates Parseoni taluka, Ramtek taluka, and Mauda taluka and provides water for the NTPC Mauda Super Thermal Power Station and other industrial purposes.

Pench River is a tributary of the Kanhan with its confluence at Bina village, upstream from the Nagpur Municipal Corporation’s (NMC) Kanhan water treatment plant.

C. (iii) Kolar River

The Kolar arises near the Madhya Pradesh border in the Chorkhairi West Reserved Forest in the north- east corner of the Katol taluka at an elevation of approximately 600 meters. It flows southeast for about ten kilometers passing through the Pilkapar range and then past the village of Pipla on its right.

The river then turns east for four kilometers toward the village of Tidangi, where the Kolar Dam Reservoir. Past the Kolar Dam it continues east for about four kilometers before turning southeast again just before the village of Hetisurla. Another seven kilometers brings the Kolar River to the center of the town of Saoner (Savner). It continues southeast past the town of Patansaoangi, and receives it major tributary, the Chandrabhaga Nadi at 21°19′24″N 79°01′11″E. Continuing southeast it enters the Kanhan River from the right at the village of Tola just above the town of Kamptee. The entire course of the river is in Nagpur district and is essentially a seasonal stream.

C. (iv) Catchment Area

River Pench-Kanhan serves as a major drinking source for Nagpur district. Kanhan River’s catchment area covers Madhya Pradesh & Maharashtra States from origin to confluence point at Wainganga River in Maharashtra State

Kanhan water supply scheme was commissioned in four phases. Under this scheme, two intake wells and two dry wells in Kanhan River are constructed. Raw water is pumped to conventional Treatment Plant of 109 MLD capacity. A barrage was constructed across Kanhan River about 500 m upstream Kanhan head works with a storage capacity of 7.82 Mm3. The average monthly discharge of the River Kanhan is maximum in the month of September i.e.760.78 cumecs and minimum in the month of June i.e. 48.96 cumecs (2014 data).

D. (i) Land Use & Demographics of the study area:

Gondegaon OC falls under Parseoni Tehsil, Nagpur District and the Land Use/Land Cover around 10 km radius of Gondegaon OC covers most of the villages & towns under Parseoni Tehsil & Kamptee Tehsil with a population of approx. 3,80,295 (as per Census 2011). The major Land Use class is agriculture and barren land Agriculture activities mainly plantations, cotton and rice in (Major) and jawar, tuar, wheat in (minor). The other Land Use classes settlements and industrial establishments including 5 OC Coal mines namely, Singhori OC, Bhanegaon OC, Gondegaon OC, Inder OC, Kamptee OC are situated along the river basin and 2 Thermal power plants namely, Koradi Thermal Power Plant & Khaperkheda Thermal Plants with 620 MW & 1340 MW capacity respectively and other medium & small industries are situated near the study area. The ash ponds generated due to the thermal power plants area a prominent land use contributing air pollution. LU/LC Map of the study area during the year 2004 and 2016 (Fig.3 & Fig.4)

E. (i). Riverine Eco-System

The ecology of the river refers to the relationships that living organisms have with each other and with their environment – the ecosystem. An ecosystem is the sum of interactions between plants, animals and microorganisms (Biotic) and between them and non-living physical and chemical components (Abiotic) in a particular natural environment.

River ecosystems have major components given below:

a) flowing water that is mostly unidirectional b) a state of continuous physical change c) variability in the flow rates of water d) Plants and animals that have adapted to live within water flow conditions.

Components of Riverine Eco-System: Abiotic & Biotic Abiotic factors: The non-living components of an ecosystem are called abiotic components namely Air quality, River/water (quantity & quality), Light, Temperature, Chemistry, Substrate act as an important factors of the Eco-System.

Biotic factors: The living components of an ecosystem are called the biotic components namely Bacteria, Primary & secondary producers and consumers, Insects and other invertebrates fish and other vertebrates.

E.(ii) Terrestrial Ecology (Flora & Fauna): The vegetation in the study area is tropical dry deciduous type. Trees include Ficus glomeruta, Butea monosperma, Schleicera oleosa. Shrubs are mostly Lantana camera, Anona squamosa, Ipomea pestigridis, Melia azardiraachata andherbs are mostly Cassia tora, Teprosia purposria and various grasses which are used as fodder for cattle. Wild animals are sometimes being seen by local villagers include i.e Canis aureus (Jackal), Macacus rhesus (monkey), Petropus spp. (Bats), Semmopithous entellus (langoor) are common. Amongst birds Columba livia (pigeon), Corvus splendens (House crow), Coturnix coturnis (Bater), Callus domesticus (Fowl), Passer domesticus (house sparrow) are most commonly reported in the study area.

E.(iii) Aquatic Ecology: The vegetation along the Kanhan River is mostly bare showing scanty population. During premonsoon Cassia tora and other grasses along with Oldenlanida spp. Parthenium histerofolius, Cida acuta, Hyptis swveolans are recorded from the river banks. Bacopa moneria was semi aquatic plants along with marshy plant Polygonum glabrum, Eclipta alba, Killinga triceps, Ammania becifera, Phyllanodiflora.

River fauna is moderate in quantity and quality. According to the information gathered from, Inland- fishing activities are being carried out in Kanhan River, ponds, tanks and in reservoirs. Species of Major Carps, which are found in the area, are Catla (Catla catla), Rohu (Labaeo rohita) and Mrigal (Cirrhinus mrigala) and Minor Carps. Species of local major like Murrels, Clarius batracus, Bam etc. were found in this region. Similarly catfishes like Wallago attu, Pangasie etc are found. The fishes of commercial value in this region are of Major Carps and Local Carps.

Plankton: About 20+ algal species mainly belong to Bacillariophyceae which mainly represent Pennate diatoms comprising Fragillaria sp, Navicula sp, Nitzschia sp, Pinnularia sp, and Pleurosigma sp. followed by

Chlorophyceae were reported. About 6 zooplankton species of Nauplius larva, Daphnia, Ceriodaphnia were reported in the study area.

F. (i) Assessment of Impacts due to Coal Mines on the Riverine Eco-System. Mining effect on air quality is of limited extent i.e. the particulate matter, SOx, NOx from vehicles may be transported upto a maximum extent of 500 meters from generation sources/point. In the present area, 2 Nos of Thermal Power Plants viz Koradi & Khaperkhera Thermal Power Plants along with their associated fly ash dumps exist. The air pollution from these can travel upto 20 kms with predominant direction towards South East in the same direction as the flow of Pench Kanhan & Kolar Rivers and may contribute to deteriorated Air quality, especially in the dry seasons. Kapherkhera TPP is adjacent to Kanhan River and one of its Ash Pond is 0.35 km away from the Pench River. The Ash ponds of Koradi TPP is 0.6 km from Kolar River and Koradi TPP is 1.8 km away from Kolar River. The important mining activities of opencast Coal mines which can have impacts on riverine ecosystem are placed below:

a. Deposition of Air pollutants from mines. During mining following activities may result in generation of Air pollutants.

(i) Drilling : SPM, PM10, PM2.5, SOx & NOx

(ii) Blasting of coal and overburden : SPM, PM10, PM2.5, SOx & NOx

(iii) Handling of coal : SPM, PM10, PM2.5, SOx & NOx

(iv) Overburden handling : SPM, PM10, PM2.5, SOx & NOx

(v) Dump formation (internal) : SPM, PM10, PM2.5, SOx & NOx

till the development of green cover

(vi) Movement of vehicles : SPM, PM10, PM2.5, SOx & NOx b. Mine water discharge During mining following activities may result in water pollution. (i) Mine Water Discharge (Seepage of strata water into the mine due to intersection of Groundwater table) – TSS, DO, PH (ii) Acidic mine water discharge : PH, DO, COD (ii) Effluent from workshops : PH, TSS, COD (ii) Surface runoff of sediments/soil from OB/Mines. : TSS

F. (ii) Mitigation Plan for Control of Environmental Pollution. Following measure are being implemented in all the opencast mines of WCL situated along the Kanhan River Basin

Air Pollution Control Measures a. Drilling & Blasting Operations

In order to reduce dust generated by drilling operation drills are fitted with Dust extractors. In order to minimize the generation of dust during blasting, the following measures have been and will continue to be adopted: (i) Proper placing/spacing/positioning of blast holes. (ii) Proper design of blast considering the actual geo-mining conditions. (iii) Blasting is done between shifts or during the rest interval when the minimum number of persons is present around the blast area. In order to quickly disperse the dust generated in blasting operations, blasting is avoided when there is wind. Blasting is avoided in the mornings and during cloudy situations. (iv) Adaptation of Controlled Blasting Technique as permitted by DGMS, wherever required. b. Coal Handling Plant, Loading & Transport The crusher house has been covered with green fibreglass corrugated sheet which has resulted in significant reduction of dust during crushing. The loosened overburden material as well as coal, as far as possible is being and will continue to be wetted first with help of water spray arrangements before the start of loading operations. Movement of vehicles and HEMM on haul roads, particularly when they are not metalled, is another major source of dust generation. To minimize dust generation due to this operation, the following abatement measures are in place & will continue to be maintained & operated. Some of the existing measures are further enumerated along with exhibits. To minimize the dust generation during coal transportation the roads has been black topped along with avenue plantation. c. Plantation has been undertaken in the mines as mitigation measure against air pollution, noise pollution and to increase the aesthetic value. d. Regular monitoring of Environmental Attributes is being carried out at 4 different locations including core & buffer zones for monitoring of air quality and for further strengthening/ augmentation of additional measures if needed The details of Mine wise Air Pollution control measure are given below:

Proposed additional measures for control of Dust control:

d) Installation of Comprehensive mist sprinkler system for dust suppression for strengthening of air pollution control in crushers, along conveyors belt, transfer points, bunkers of 2 CHPs of Gondegaon OC.

e) Proposal for strengthening of existing dust suppression into chemical dust suppressant system through use of chemical dust suppressant is under consideration.

20 f) Further to eliminate air pollution due to coal transportation by road, the main consumer i.e. M/s.MAHAGENCO has planned to take coal from the Gondegaon OC along with coal from neighboring opencast projects namely Bhanegaon OC & Singhori OC through Pipe Conveyor to their thermal power plants at Koradi and Khaparkhera. The work is being awarded by MAHAGENCO. WCL will arrange to provide its acquired land to the maximum extent for the construction of the pipe conveyor system and the expected timeline is 24 months. The route plan is shown below:

Water Pollution Control Measures a. Mine Water Two stage sedimentation process commissioned, first in sump of quarry floor & second on surface sedimentation tanks of sufficient capacities are in operation. First, the raw mine discharged water is collected in a sumps in the quarry floor, where the coal particles are settled down and then after the water is pumped out for further treatment through sedimentation ponds before discharging to the outside the project area. b. Acid mine discharge Acid mine discharge is due to presence of Pyrite bands along the coal seams and it is not present in all the coal mines. In the above said study area’s geological formation does not have pyrite bands none of the coal mines are acidic in nature. c. Industrial Effluent & Mine water ETPs of sufficient capacity with oil skimmer/ (O&G Trap) has been installed near the washing ramp of the workshops where the discharged water is being properly treated for having a zero discharged system. The ETP sludge is being treated properly at CHWTDFS, Buttibori before final disposal. d. Surface runoff of sediments/soil from OB/Mines. Adequate numbers of vegetation are grown on the top surface and slopes of the dumps in order to arrest the erosion of soil and it also reduces surface run-off, which helps averting siltation of Natural watercourses.

In the said opencast projects, to arrest the silt, Catch drains with sufficient length & breadth dimensions have been constructed around the OB dumps. The same is regularly de-silted and maintained properly. Garland drains are also provided around the quarries. Catch drains are provided around the OB dumps to collect the run off & silt during peak rainfall. In OB benches, cross drains are provided which collect all silt & run off to the mine sump having sufficient capacity to deal with peak rainfall. These mine pumps provide sufficient settling time for suspended particles. As expansion project shall commence, the Garland drain/catch drain shall be extended suitably. Embankments of minimum 6 meters height above HFL on the river side are constructed and strengthened by plantation and stone pitching (wherever necessary) on the sides. e. Regular monitoring Monitoring of Environmental Attributes is being carried out at effluent points of sedimentation tanks & workshop ETPs for monitoring of water quality and for further strengthening/ augmentation of additional measures if needed The details of Mine wise Water Pollution control measure are given below:

G.(i) Conservation of Natural Resources – Proactive Steps taken by WCL under its Social & Environmental Responsibility: The land use around the Gondegaon OC Coal mine comprises majorly agricultural land with settlements of Parseoni & Kamptee Taluk, 2 Thermal power plants along with ash ponds and other small & medium industries are the major consumers of water sources. Nagpur, Kamptee, Kanhan Towns & other villages draw water from the rivers and dug wells for drinking & domestic purposes and for agriculture, locals depend on rains & rivers.

2 Nos thermal power plants, Koradi & Khaperkheda Thermal Power Plants with installed capacity of 1960 MW needs 218 MLD of water for which it depends on river for its water requirements. These activities cause stress on the river & groundwater sources.

Whereas in opencast coal mines of WCL, groundwater and river water ingression through strata seeps into mines due to excavation, drilling & blasting (in turn causes fractures) activities. In mines at working floor, for the safety of the machine, manpower and operations, this seepage water is diverted through catch drains or cross drainages and collected into a sump/sedimentation tank with sufficient residence time for settlement of soil particles/ suspended solids particles and then the supernatant is pumped on to surface sedimentation tank for further treatment for reuse in the mines for domestic & industrial purposes and remaining discharge into nallas. Drilling, blasting and excavation affect the fracture properties such as Porosity and permeability. An increase in fracture aperture will result in an increase in fracture or induced permeability. A commonly used relationship between fracture permeability and aperture is known as the Cubic law, which shows fracture permeability to be proportional to the cube of the fracture aperture.

Also the area around the OC coal mines have increased levels of groundwater tables due to greater average infiltration capacity induced by mining activities.

The effect of mining in the OC mines on groundwater levels have been already carried out. The zone of influence calculated as per GEC 1997 norms works out to be a maximum of 1000 m from the working face. The average amount of water pumped out from the 4 OC mines (Singhori is excluded since it’s a new mine and full operations are not yet started and it has not intersected water table) in the study area is approx. 32.8 MLD. Monitoring of groundwater levels and quality is being done on regular basis. WCL has undertaken a new initiative for minimizing the dependency on water around its mines. Under this new initiative, WCL is providing treated Drinking water and for agriculture & domestic purposes benefiting local populace of more than 50,000 from the mine water by this way meeting the daily requirements for different purposes and minimizing the dependency of populace on river water and ground water. These efforts have reduced the stress on the riverine ecosystem and groundwater thereby minimizing the water foot prints significantly. Apart from the benefit of local populace, WCL has signed a MoU with Maharashtra Govt. to provide 10.76 Million M3/ year water from the OC mines to Thermal Power Plants thereby minimizing TPP’s dependency on the River water thereby distressing the riverine ecosystem considerably. Further WCL is about to sign an MoU with VIDC (Vidharba Irrigation Development Corporation) for providing water 28.16 Million M3/year for irrigation purposes from the mines of Nagpur Area of WCL. After the exhaustion of coal reserves, the OC mines continue to contribute to Eco-system & Riverine Eco-System. The environmental protection measures like afforestation, mine void will improve air quality, recharges groundwater levels etc. Mine wise Pre-Mining & Post- Mining Land use details are given in the table 10

The induced permeability, porosity, water body & generation of biologically reclaimed areas will acts as a water capture & conservation area and will improve the base flow of Kanhan River in the non- monsoon period, which will help the downstream dependent on river. The increased base flow will also help in rejuvenating and increasing the flora & fauna both aquatic & non- aquatic thereby improving the quality of riverine ecosystem.

Conclusion:

Coal mining has effects on the environment & ecology of any area. The effects can be both positive and negative and have to be appreciated in their correct perspectives.

The present case related to mining along Pench-Kanhan River at sites where they merge or in their last stages of journey prior to confluence. Both the rivers, on date, are seasonal. Also as per listing in Central Water Commission both Pench as well as Kanhan River basins don not form a part of major & medium river basins.

Mining Projects of WCL are located in downstream areas of Pench & Kanhan Rivers. Two dams on Pench River exist in upstream and the base flow in the river is already constrained.

The competing stakeholders of water are power plants, ash dumps, irrigation and industries in addition to local authorities for drinking water supply. Study of the areas have highlighted that the mine under discussion is in a topographic high and its pre-mining status as per remote sensing study is barren waste land with shrub.

WCL with its mining activities has planned for improving the ecological aspects in the said area. The activities such as drilling & blasting are certain to improve the permeability in the area. The area excavated post backfilling & biological reclamation would also experience increased water holding capacity.

The voids would act as water storage structures and improve the hydrogeological aspects of the area. The biologically reclaimed dumps (both external & internal) & water bodies will help in improving the micro-climate of the area. All these combined are expected to augment the present day base flow of the Kanhan River. As the base flow improves the riverine ecosystem will be benefited by increase in the floral & faunal elements. WCL on its part will also ensure that a major part of strata water generated from its mines is supplied to stakeholders like power plants, irrigation authorities & industrial parks by way of an MoU. Also, drinking water requirement of the nearby populace is already getting benefitted by the treated mine water already being shared by WCL mine officials. The riverine eco-system is bound to improve by the mining activities of WCL.

Thus from the above, it is seen that the mining potential and prevailing environmental concerns vis-a-vis the riverine ecosystem of the area have been adequately addressed. It has also come out in the above study that the mining activities are contributing towards releasing undue stress on the ecosystem there by maintaining the existing carrying capacity unaffected.

In addition to the specific conditions which are site specific, generic conditions are regular in nature and compliance of generic conditions will be continued till the life of mine. ix. A mitigation plan based on the study to be submitted to the MoEF & CC Regional Office / SPCB and displayed on company’s website. Compliance: The existing pollution control measures have been incorporated in the study report detailed out in the compliance given at point no.(viii) above. Further the proposed measure have also been given in the aforesaid study report. On acceptance by the Ministry, the study report will be uploaded in the company’s website.

3.0 Conclusion:

In view of the above, we most earnestly solicit your good office to consider our submission for Extension in validity of EC granted to Expansion of Gondegaon Extension OC Coal mine vide letter no.J-11015/106/2009—IA. II(M) dated 14-03-2018 in line with the EIA Notification , 2006.
