and soil quality, etc., in core zone and buffer zone (i.e. 10 km radius study area) of Cluster of GDK No.1&3 Incline and GDK Coal Mine (No.2&2A and No. 5) Opencast cum Underground Projects. The environmental baseline data conforms to the requirement of EIA Notification, 2006 vide S.O. 1533, on 14.09.2006 and subsequent amendments, and ToR issued for the project. 3.1 Physical Resources Physiography The buffer zone area is of flat to gently undulating terrain, dotted with hillocks and intervening sand patches. The buffer area is drained by River Godavari. It enters into the buffer zone from the northwest side and flows south easterly, dividing the buffer zone into two parts. The area on the north-eastern side of River Godavari slopes towards southwest (i.e., towards ), while the area on the south-western side of River Godavari slopes towards the northeast (i.e., towards Godavari River). In general, the surface elevation of the buffer area on the northern side (Left bank) of. River Godavari varies from North eastern periphery (i.e., 200m above MSL) to South western side (i.e., towards Godavari River, 120m above MSL). While the area on the southern side (Right bank) of River Godavari varies from 200m above MSL to 120m above MSL. The mean topographic slope of the buffer area on northern and southern side of the River Godavari is 11.96m/km and 4.51m/km, respectively towards River Godavari. In the western part of the buffer zone, rocky knobs of 277m above MSL, 211m above MSL and 311m above MSL (i.e., near Ramagundam R.S.) are located on the Western side. The Nagula gutta (422m above MSL) is located outside the south-western periphery of the buffer zone. While on the north eastern part of the buffer zone, an unnamed hillock (411m above MSL) is located in the eastern side. Along the Godavari River the area is periodically flooded and the flood plain is well drained and comprises of thick un- consolidated alluvium ranging in thickness from 1.8m to 3.0m. Drainage The buffer area is drained by south easterly flowing Godavari River and its ephemeral tributaries viz., Jallaram vagu, Bokkala vagu, Tolla vagu and Tekumatla vagu (Peddavagu). In the Southern part of the buffer zone Jallaram vagu drains the central part, while Bokkala vagu drains the southern part; both these tributaries confluence with River Godavari at Siripurm and Khanapur villages, respectively. The northern part of the buffer zone is drained by southerly flowing Tekumatla vagu and south westerly flowing Tolla vagu. The Cluster of GDK No.1&3 Incline and GDK coal mine (No.2&2A and No.5) are falling in the Jallaram watershed area. The catchment area of Jallaram vagu is 138 sq.km. It originates at Nagula gutta at about 10km west of the project and flows towards northeast and join River Godavari. The drainage is of dendritic type with a density of 3.6 km/sq.km. The highest flood level (HFL) of Godavari River recorded at intake well near GDK-1 Inc. on 10th October, 1995 is 138.10m above MSL. 3.2 Meteorology The area experiences typical tropical climate of a distinct hot summer from March to June with occasional dust storms, a good monsoon between June and September and a pleasant winter from October to February. Meteorology data at the site was monitored during March 2019 to May 2019 representing the Summer season. The predominant wind direction is blowing from South-South East (SSE) direction and calm conditions prevailed for 26.31% during the season. The maximum wind speed recorded was 11.4m/s. The maximum temperature recorded was found to be 46.90C, while the minimum temperature was 13.20C and the average temperature is 34.30C. The average relative humidity was found to be 45.6%. The solar

radiation is found to be in the range 0.0 to 884.0 W/m2.The total rainfall observed during this study period is 8.0 mm. 3.3 Air Environment

Different air pollution parameters like particulate matter of less than 10μm size (PM10), particulate matter of less than 2.5μm (PM2.5), Sulphur Dioxide (SO2) and Nitrogen Oxides (NOx) and Carbon monoxide (CO) have been identified as critical parameters relating to project activities for representing baseline status of ambient air quality within the study area in accordance with the Terms of Reference (ToR) issued by MoEF&CC. To assess the base line Ambient Air Quality Monitoring (AAQM) was carried out at 15 locations with a frequency of two days per week for three months during Summer season of 2019. Core Zone:

Ambient air quality data monitored in the core zone shows that PM10 concentrations varied 3 3 from 180.2 to 221.6 µg/m . PM2.5 concentrations were in the range of 52.4 to 68.4 µg/m . 3 3 The SO2 and NOx concentration varies from 9.6 to 18.0 µg/m and 14.2 to 28.1 µg/m respectively. The CO concentration is observed to be below the threshold values. All the parameters are found to be within prescribed limits as per Coal mine Standards. Buffer Zone: 3 3 The concentration of PM10 varied from 42 µg/m (Chillapalli Village) to 85 µg/m 3 (Kanchanpalli village). The PM2.5 concentration varied from 22.7 µg/m (Chillapalli village) 3 to 54.7 µg/m (GodavariKhani Village). The SO2 and NOx concentration varies from 9.9 (Shetpalli village) to 22.2 µg/m3 (Sundilla Village). and 12.7 µg/m3 (Shetpalli village) to 28.1 µg/m3 (Sundilla Village) respectively. The CO concentrations are observed to be below the threshold values. All the values were found to be within the prescribed limits as per National Ambient Air Quality Standards prescribed by MoEF&CC. 3.3.1 Mineralogical Composition The mineralogical composition for the Particulate Matter of size less than 10μ was analyzed at all air quality monitoring locations within the 10 km radius of the study area. The samples were analyzed for Chromium, Nickel, Arsenic, Cadmium, Mercury, Lead, etc. The values are verified with NAAQS standards for arsenic, lead and nickel. Arsenic is not present and lead, nickel is well within the limits, other metals like aluminium, iron and zinc are due to geological conditions. 3.4 Noise Levels A detailed noise survey was carried in and around the mine site to study the hourly equivalent noise levels. Equivalent noise levels were measured on hourly basis during 24 hours by using a High Precision Sound Level Meter at 15 locations within the study area of the project. In core zone, maximum value of Day Leq is 69.0 dB (A) GDK No.2 & 2A Mine and maximum value of Night Leq is 56.8 dB (A) at GDK No.2 & 2A Mine. In the Buffer Zone maximum value of Leq Day is 50.7 dB(A) at Peddampeta and minimum is 40.8 dB(A) at Godavarikhani (Sector-1) and maximum value of Leq Night is 43.5 dB(A) at Peddampeta and minimum is 34.7 dB(A) at Kanchanpalli Village. It was observed that the noise levels measured during day time and night time in the core as well as in the buffer zone of the project are within the stipulated standards. Traffic density The traffic density study has been carried out at four locations (i.e. (GDK No.5 Incline nursery ‘Y’ Junction – point 1), (After GDK No.5 Incline Vittalnagar Junction - point 2, Near GDK No.2 Incline towards RG –I CHP- point 3 and In between GDK No.5 Incline ‘Y’ Junction and RG OC-III CHP- point 4).

The peak PCU/hr for total vehicles during the study at point-1 is 271 PCU/hr at 16.00 PM-17.00 PM, Point-2 is 553 PCU/hr at 09.00 AM-10.00 AM, Point-3 is 484 PCU/hr at 18.00 PM - 19.00 PM and Point-4 is 843 PCU/hr at 14.00 PM-15.00 PM. Based on the traffic studies V/C ratio and LoS were calculated for four points of coal transportation route. Two scenarios were considered, one scenario is based on the existing traffic level and other including the coal vehicles of the proposed project. It is observed that in two scenarios the level of service remain unchanged for point 2, 3 and 4 whereas point-1 the level of service where found to be changing from A category to B category. 3.5 Water Quality The major water source in the area is water tanks and ground water. The impact of the project on the water environment is assessed by studying the water quality of ground water and surface water body sources within the study area. The sampling stations were identified considering the proximity to project site and its effect on the water quality. A total of 14 water samples i.e. 5 samples from surface water sources, 6 samples from ground water sources, and 3 samples of effluents were collected and analyzed for various physico-chemical and bacteriological parameters. The water quality results were compared with the standards of ground water quality, IS: 10500, surface water quality with CPCB water quality criteria and effluents quality was compared with General Standards for Discharge of Environmental Pollutants, Part–A: Effluents, GSR 801 (E). Ground water The analysis results of groundwater samples were compared with IS:10500 of Acceptable and Permissible limits, which are stipulated for water to be fit for drinking purpose with groundwater as source. • pH values are in the range between 7.1 to 7.7. • TDS and Total Alkalinity are above the acceptable limits and below the permissible limits at all the locations, whereas Chlorides are above the acceptable limits at GW-4 (300 mg/L),GW-5 and (362 mg/L). The parameters might have exceeded due to underground strata conditions. • The concentration of Iron (as Fe), is above the acceptable limit of 0.3 mg/L at all locations except at GW-2 (0.24 mg/L), GW-4 (0.10 mg/L), GW6 (0.07 mg/L). • The concentrations of heavy metals Cadmium (Cd), Copper (Cu), Lead (Pb), Selenium (Se), Arsenic (As), Chromium (Cr), and Nickel (Ni) are below the detection limits, whereas Manganese (as Mn) is below the acceptable limit at GW-1 and GW-3 and in other locations it is below the detection limit. • The ground water quality in the study area indicates that iron and total hardness is exceeding the stipulated limits in some of the samples and hence ground water needs to be treated prior to its use for drinking needs. Surface water The analysis results of surface water samples are compared with CPCB water quality criteria. In accordance with CPCB water quality criteria, parameters studied were pH, DO, BOD and total coliforms.  pH values were found to be in the range 7.5 to 8.2.  It may be observed that all the surface water samples have DO values ranging from 5.8 mg/L to 6.7 mg/L.  BOD was found to be above the stipulated limit of CPCB water quality criteria.  Total coliforms and fecal coliforms were present in all the surface water samples collected in the study area.  E. coli was absent in all the surface water samples collected within the study area.

NOC for operation of the mine with respective Siwaram Wild Life sanctuary will be obtained from NBWL. 3.8 Socio-Economic Environment The mining area is surrounded by 40 census villages in the 10 km radius of the study area. Secondary data for the census villages was collected from the Census 2011. A sample survey of 409 households was surveyed in 18 villages of the study area. It was observed that about 38.4% of them are illiterate, 61.6% are either literate. Education status has improved very little from generation to generation in this region. Schooling is available up to secondary education. Anganwadi centre are available in these villages. Road network and transport facility is fair and communication facilities are good. 23 % of the people are engaged as daily labourer. The study area is not agrarian area and there are only a few farmers cultivating mostly Paddy and Cotton, some are cultivating chilli and few are growing fodder for their own cattle. Out of 409 households surveyed, 28% are having agriculture land and 72% do not possess any agriculture land. Most of farmers do not possess costly agricultural related goods like trucks and tractors. However, they have access to these services on rental basis. All the households own their homestead plot. 31% were living in pucca houses, 55 % in semi pucca houses and remaining only 14% respondents were dwelling in kutcha houses. With regards to water sources, 70% families were using water facility from rural water supply, 21 % families were using bore well, and 7% were using drinking water from Open well. All the villages are having clean drinking water facility. The sanitary status was good in the villages as 87% have sanitation facilities in their own premises, 6% are utilizing community toilets and only 7% of respondents are going for open defecation. It was observed that 86% of households using LPG for cooking purpose and nutrition food intake are moderate level. In the area of consumer durables almost all the household possess fan as their minimum requirement, 84% of households possess television, and 37% of households possess refrigerator and 98% of households having mobile phone for their communication purpose. Health and medical amenities were adequate as most of the villages were covered by the Rural Medical Practitioners (RMPs) and within the study area 2 PHC, 4 Urban PHC, One Area Hospital and more than 20 private hospitals are available. 4.0 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES The section summarizes the pollution potential of the proposed project, possible impacts on the surrounding environment during pre-operational and operational phases and the environment management plan proposed for prevention and control of pollution. The impacts on environment due to the underground mining are very less compared to the opencast mining operations. The environmental impacts due to the proposed mining, associated activities like drilling, blasting, overburden, loading, overburden & coal transportation and coal beneficiation have been assessed and adequate management plan has been developed to mitigate the impacts. 4.1 Impact on Air Quality and Its Management Mining operation and associated activities are potentially air polluting and major air pollution is the Particulate Matter (PM10). Most of the air pollution problems are due to fugitive dust emissions which is more prominent in opencast mines in comparison to underground mines. The likely sources of air pollution in underground operations will be generation of

E P T R I Executive Summary of EIA & EMP report for Cluster of GDK 1&3 Incline and GDK Coal Mine (No.2&2A and No. 5) Opencast cum Underground Projects

dust during mining operation viz. mine exhaust air, transportation of coal & material and generation of dust from coal handling operation like screening, crushing, etc. The opencast mining includes drilling, blasting, vehicular movement, waste dumping etc. These activities are likely to contribute predominately Particulate matter and oxides of nitrogen. The existing baseline concentrations of the pollutants are within the limits as prescribed by CPCB. Further, the predicted value concentrations are also will be within the permissible limits. The air pollution mitigation measures, which will be implemented during the operation of the mine are as follows: Underground Mining Operations: The dust pollution control measures suggested are more as preventive measures because the generation or emission is not through stacks but from various mining activities and is fugitive in nature. The following measures are being implemented for air pollution control: • Effective water spraying arrangements in underground working places as well as at coal loading bunkers at pithead on surface. • Water spraying arrangements are made by suitable means at underground haulage roadways, junctions and other transfer points • Enclosures at coal transfer points. • Water spraying arrangement along coal transport route within the mine premises. • Regular clearing off coal dust heaps on surface. • Black topping of coal transport route. • Watering of roads at regular intervals. • Plantation within the mine premises and also along coal transport route • Proper periodic maintenance of vehicles, etc. • Trucks carrying coal will be covered with good quality tarpaulin. • The underground workings of the mine will be well ventilated by adequate ventilation arrangements. The requirements and standards specified in this regard by Director General of Mines Safety (DGMS) would be adhered to. • Mitigating measures to suppress the dust liberated due to the transportation of coal are being taken up regularly by water spraying arrangements at all transfer points, critical areas, loading and unloading points in the CHP. Open Cast Mining Operations: While complete elimination of dust due to mining operations may not be possible, the following measures will be taken to mitigate the fugitive dust from different operations in the opencast mine: • To avoid dust generation from the drilling operations, wet-drilling methods will be adopted. • Appropriate explosives (NONELs) will be used for blasting and overcharging of blast holes in OB will be avoided. • The volume of dust rising from dumps by the action of wind will be controlled significantly by planting grasses on slopes and native plants on dumps soon after their formation. • Haul roads are major source of dust in the opencast mines. To overcome the problems of dust generation from mine haul roads, the following steps are being taken. - Black topping of permanent roads like routes to coal handling plant, permanent internal roads etc. - Water spraying on haul roads and permanent transport routes will be done at desired frequencies. Twelve 28 KL water sprinklers will be deployed for spraying of water on haul roads and in reclamation works. - Coal dumpers will be wetted by water sprinklers on surface - Avenue plantation along the transport roads. 11 Prepared by EPTRI, Hyderabad

• Taking up plantation around the quarry and OB dumps in three rows, which will serve as a barrier to prevent the dispersion of dust. Greenbelt development will be taken up around the quarry, service buildings, over reclaimed area and OB dumps. • Effective dust suppression measures will be taken up at pit head coal handling plant (CHP). The crusher house is enclosed with permanent structures and dust suppression arrangement is provided at transfer points and other dust generation points in the CHP. All conveyors, screens, crusher etc. are provided with permanent covers to avoid fugitive dust during operation. Some of the measures being adopted at CHP in order to control dust emission include: i. Height of fall to be minimized at all coal transfer points. ii. Internal lining of chutes and bins are done to take care of abrasion & dust iii. Suitable mist spraying arrangement for dust suppression is provided and the system is so inter-locked that it functions only when the conveyor system is operating or the loading operation is on. iv. Mobile mist spray machines will be deployed for dust suppression at pit head CHP. • The exhaust emissions from HEMM containing CO, SO2 & NOx will be controlled by strictly adhering to the scheduled maintenance that includes periodical tuning of engines. 4.2 Impacts on Noise Quality and its Management In the underground mining as most of the operations are carried in the underground, there will not be any significant impact on the existing noise levels due to UG mining. The only increase in noise levels could be due to coal dispatch arrangements and surface mine ventilation fan and the same will be abated by developing a green belt around fan house and mine site. In the opencast mining operations, the increase in noise levels is due to running of machinery, drilling and blasting for Coal/OB removal, excavation, transportation and crushing of coal/OB, it is imperative that noise levels would increase. High noise levels will be confined to the mining areas only and the nearby villages and other community areas will not likely to have any major adverse impact as noise levels will attenuate with distance. In opencast operations, as per the recommendations, blasting parameters such as burden, spacing, charge per delay, sub-grade drilling is being maintained. Controlled blasting techniques like use of NONEL and Site Mixed Slurry (SMS) will be followed to minimize the noise and vibration. These type of practices will be implemented during the operation of mine. Further, all the operator cabins in HEMMs including dozer and drill will be made air tight and air conditioned. Acoustic enclosures will be provided in the DG sets. All the workers will be provided with ear muffs. Further, greenbelt will be developed around the mine lease area, along the OB dump areas and in the colony acts as noise attenuator. The following precautions will be taken up for controlling Noise levels and ground vibrations at the site. Underground mining operations:  In UG mine the mines the main mechanical ventilators are provided with evasees, which allows smooth flow of air and dampens the noise.  Height of fall of coal is minimized at all coal transfer points and internal lining of bins and chutes is done.  In the high noise intensity working areas / zones earplugs are provided to the workmen.  Regular noise level monitoring is done periodically for taking corrective action, wherever required.  Extensive plantation of green belt and vegetation along the roads and around the offices is done to create a barrier or screen between the source and the receiver so that the noise is absorbed and the exposure level is minimized.

As the present underground workings are planned at deeper depths there will not be any impact on the surface due to blast induced vibrations. Opencast mining operations: Blasting in opencast mines in particular is of sporadic activity and the event takes place only once or twice in a day during mid-day time. Other associated opencast activities like drilling and movement of HEMM are also of interrupted type. Some of the precautions proposed to be implemented for noise reduction are:  Controlled blasting technique is adopted in this project for reducing blast vibrations substantially. The experience gained in other OC mines would be gainfully utilized to keep the peak particle velocity within limits.  Further, charge per delay is regulated to minimize blast vibrations.  Optimum delay sequence and stem to column ratio is maintained to minimize the fly rock distance and ground vibration intensity.  Basing on the distance of the nearest sensitive areas from the epicenter of the blast, charge weight will be altered to meet the stipulated standards.  Design of optimum blast hole geometry considering bench height, diameter of hole, type of explosive, nature of rock, level of fragmentation required etc.  The total charge / blast is divided into several parts so as to keep minimum explosive per delay i.e. use of milli-second delay detonators & relays.  Avoid concentration of explosive by using deck charging Management of Fly Rock:  Muffled blasting will be done wherever any blasting is to be taken within 100m from the structures.  In loose and fractured rock mass, low-density explosive will be used.  Proper burden and spacing will be maintained according to the bench height and diameter of holes.  Length of stemming column will be maintained greater than 0.6 times the burden.  It will be ensured, as far as possible, that the holes to be located beyond weak zones.  All loose pieces of rock from the blasting site will be cleared before charging.  Warning signals: An audible warning signal will be given, fifteen minutes before actual firing of blast to enable persons to move out of danger zone. For this purpose, a set of sirens/hooters will be provided at appropriate places.  Blasting shelters will be provided in close proximity to the site of blasting for taking shelter during blasting in order to protect the personnel engaged in blasting operations. 4.3 Impacts on Water Quality and its Management In the process of mining, water will be accumulated in the dip most places of the mine due to natural seepage and mining operations such as stowing operations etc. The water so accumulated is collected in sumps at different places in the mine and is pumped out to the surface with suitable capacity pumps. The pumped out water is filtered on surface to make it potable and used for drinking (after treating by RO) and other purposes on the pit head as well as in the colonies. The total quantity of water pumped out from this cluster mines is around 16040 KLD. The mine requirements is about 6720 KLD being utilized for project requirement like dust suppression (2750 KLD), workshop/ fire fighting (280 KLD), Domestic use (840 KLD), plantation (150 KLD) about 1000 KLD of water will be supplied to the nearby villages/ colonies for domestic usage after treatment and remaining left out water of 8320 KLD will be let out into nearby stream/tanks for irrigation. Mining activities may cause adverse impacts due to pumping of mine water, siltation due to storm water, contaminated water from workshops and domestic wastewater. An impact due to soil erosion during monsoon periods is also significant in nature. The impacts on water quality are due to mine seepage and wastewater from other mining activities. The mine discharge water will be stored in settling ponds for removal of 13 Prepared by EPTRI, Hyderabad

suspended solids. A part of the treated water will be used for various requirements of the project like dust suppression, washing of HEMM, plantation and for other purposes at the mine. The excess mine water will be discharged into the nearby natural drains after conventional treatment. Proposed Water Pollution Control Measures  The mine discharge water, which may contain coal fines, needs sedimentation, before discharge into the natural water course/ open land. The treatment facilities such as sedimentation, filtration and chlorination will be provided for mine discharge, so as to conform to the effluent standards as prescribed by MoEF.  The effluents from service building will be collected by a sewerage system and treatment by means of septic tanks and soak pits. There will be no impact as the sewage is discharged after treatment.  Presently, sewage is being treated in septic tank followed by soak pit for existing townships in RG-I area. Construction of 17 MLD STP very near to the proposed project is under progress in order to treat the sewage of the nearby existing townships including the sewage of this project.  Water running through dumps is expected to get mixed with loose overburden and associated material. Garland drains and sedimentation tanks will be constructed around the OB dump and the lease area to reduce soil erosion and arrest suspended solids before discharging the run-off water into the natural water regime as well as to prevent storm water from entering the lease area. One diesel backhoe shovel is provided for preparation of garland drains, settling ponds, etc.  In addition to the above, the dump slopes will be formed with suitable inclination (overall slope 25.64o) so that the water falling over the dump will gravitate down without causing soil erosion. Regular cleaning of drains will be done for de-silting the same.  To avoid the flow of surface water towards and into the proposed quarry, suitable precautionary measure like diverting seasonal Nallahs and provision of garland drains all along quarry periphery will be taken up.  To prevent surface and ground water contamination by oil/grease and sewage waste, the following measures are adopted: • Leak proof containers are used for storage and transportation of oil/ grease. • All the precautions are taken during temporary storage to avoid oil spillages. • Oil and grease are handled on impervious area. Any wash off from the oil / grease handling area or workshop will be drained through impervious drains, collected in specially constructed pits and treated appropriately before using it for dust suppression and plantation. • ETP will be provided for work shop and CHP. • Washing platform will be provided for washing HEMM and the waste water will be collected in Effluent Treatment Plant for trapping oil and grease. The treated water is re-used for dust suppression and cleaning purpose etc.  The surface and ground water quality in and around the proposed project, and infrastructure is regularly monitored and appropriate control measures will be adopted in case of any pollutant is detected above the prescribed limits.  All stacking / loading areas will be provided with proper garland drains equipped with baffles to prevent wash offs from reaching the downstream natural drains. The excess mine water, which will be discharged into nearby tanks will be used by local villagers for agricultural purpose. This will also augment recharge of the ground water regime. As there is surplus amount of water is available within the ground water table, there is no significant impact on the ground water table. 4.4 Impacts on Land Environment and its Management GDK No.1&3 Incline: The maximum subsidence recorded in early '80s, when caving operations were conducted was 0.5 m. At present, the entire mine is being depillared in conjunction with 14 Prepared by EPTRI, Hyderabad

E P T R I Executive Summary of EIA & EMP report for Cluster of GDK 1&3 Incline and GDK Coal Mine (No.2&2A and No. 5) Opencast cum Underground Projects

hydraulic sand stowing and in particular only single section (i. e. Bottom section) of No. 3 seam which is having 9 m thickness is being liquidated under Jangaon Tank and Jangaon village. As such no impact is envisaged on the present land use. For the UG mining the existing land was already acquired for infrastructures, sand stowing bunkers, sand stock yard and office buildings. Most part of the mine is being depillared with hydraulic sand stowing to minimize land degradation. Subsidence prediction studies using 3D Numerical Modeling for the three mines were carried out by Institute of Technology, Banaras Hindu University, .The predicted surface subsidence, horizontal tensile strain and crack width are negligible for all the three mines i.e., GDK 1&3, GDK 2&2A Inclines. It is not likely to have any impact on surface structures. Hence, no subsidence management plan is being suggested. Out of 195.54 ha of the acquired land for GDK No1&3 incline green belt will be developed in about 140.67 ha by the end of the mining operations and remaining 54.87 ha will be left for public use like infrastructure and roads. GDK Coal Mine (No2&2A and No.5): GDK Coal Mine (No 2 & 2A and No 5 is a mixed mine (opencast cum underground mine) with total mine take area of 1385.47 ha. No forest land is involved in the project. GDK Coal Mine (No 2 & 2A and No 5) is conversion of Godavarikhani No.5 Incline UG mine into opencast by utilizing the surface area of Godavarikhani No.2&2A Inclines except the existing infrastructure area for dumping of OB and producing coal from GDK No.2&2A Mine. About 269.53 ha will be utilized for dumping of the OB removed from the OC operation up to a height of 120m above ground level and the entire external dump are will be reclaimed after completing the dumping operations to minimize the impact. The opencast mining operations like quarrying, dumping of overburden, approach roads and service facilities etc. will result in change of landscape and topography. Mining operations have entailed uprooting of existing vegetation in the project area diverted / acquired for the project. The private land required for the project will be acquired as per LA Act by paying suitable compensation to land losers. Opencast mining involves removal of large quantity of overburden and dumping outside the quarry in the initial years till sufficient void is created in the quarry for backfilling. The external dumping of overburden is minimised to the extent possible and reclamation will be carried out to a large extent in the project in order to reduce the disturbance to the landscape. About 328.29 ha of unexplored coal bearing area within the existing mining lease is included in this cluster project which is towards south-east and east side. Detailed exploration will be carried out in this area in order to explore the deep-seated coal reserves suitable for underground mining in future. Infrastructure facilities like pit offices, stores, workshops and offloading camp areas are planned in this land. Extensive green belt will be developed in this area and vacant areas as a part of massive plantation programme in the project. By the end of the Mining operations to reduce the impact on the land environment about 1166.24 ha will be brought under plantation and about 22.71 ha will be converted to agriculture land, 376.93 ha will be undisturbed land 129.31 ha will be left for public use and 240.94 ha will be left as water body. 4.5 Impacts on Solid waste and its Management The solid waste generated from the underground mine and its Management: • While shaft sinking in the sub soil for mine entries and driving tunnels in hard rock. • Coal extraction As these underground mines are operating mines, no further solid waste will be generated during drivage of tunnels and air shaft sinking which were already completed. However, solid waste generated during inter seam tunneling and during track laying will be used for underground track ballasting, leveling of the uneven floors and strengthening of surface bank head. Further, the rejects from mines and Ramagundam-1 CHP is being

used for laying road, filling of cracks developed due to subsidence and pitching of embankments etc. The solid waste from the townships is being collected from the collection bins and tricycles provided by SCCL. The domestic solid waste collected is being transported to the disposal sites of SCCL. The solid waste disposal sites are identified in the low-lying areas, over burden dumps and subsidence areas of SCCL. Hence, no appreciable impact is anticipated due to disposal of solid wastes. The solid waste generated from the Opencast mine and its Management: Top soil Managment: A total of 3.36 Mm3 of Top soil will be produced during the mine life of which 2.20 Mm3 will be spread over the external dump and 1.16 Mm3 will be spread over the internal dump and reclamation works will be taken up. Adequate care has been taken to preserve the Top soil in temporary storage dump yards and spread over the finished decks of dumps in the later stage in a systematic manner. The top soil is preserved in temporary top soil storage yard on the East side of the project. OB Management: Overburden material obtained during mining operations at different stages and a negligible quantity of shale / rejects separated from the excavated coal. During the process of coal excavation, overlying strata consisting of topsoil and sedimentary rock formation will be removed separately as an overburden. Total overburden excavated from the proposed Project will be 455.26 Mm3 including about 451.90 Mm3 of hard OB and 3.36 Mm3 of top soil. Out of 451.90 Mm3 of Hard OB, 197.53 Mm3 (43.7%) of hard OB will be dumped in the external dump yard from 1st year to 5th year of mine life. Balance 254.37 Mm3of hard OB will be dumped in the internal dump yard. Internal dumping will start from 6th year and will continue till the end of life of the mine. The external dump yard and internal dump yard are proposed to be merged by flushing the OB. Separate spoil dumps for Top soil and Hard OB. The topsoil will be temporarily store and it will be used for plantation schemes, no impact of dozing of topsoil is envisaged. There will be no problem for collection, handling and transport of solid wastes and there will not be any subsequent pollution of air, water and soil due to disposal or reuse of solid wastes. The liquid waste to be generated in the mine like used engine oil, gear oil, brake oils and other lubricants will be stored in separate tins/drums/cans and sent to main stores for disposal to TSPCB authorized recyclers. 4.5.1 Hazardous Waste Handling & Management The hazardous waste generated in the mine are used oil, batteries and used empty tins/drums/cans which are being collected, stored and disposed off to authorized recyclers from area stores through e-auction as per the Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2016. 4.6 Impact on Flora & Fauna As the mining activity is restricted to the core zone, no significant impact on the flora of the buffer zone due to the expansion of mine is anticipated.There are no endangered flora and fauna species within the core area. But Schedule-I species Pavo cristatus and Varanus bengalensis were recorded in the study area but their presence is common in occurrence. No national parks, biosphere reserves in the study area, however, Siwaram (Crocodile) wild life sanctuary falls at a distance of 7.72 km in the South- East direction of the project. A wild life conservation plan and mitigation measures for protection of schedule-I species and crocodiles falling under Siwaram Wildlife sanctuary has been 16 Prepared by EPTRI, Hyderabad

prepared and approved by Chief Wildlife Warden, Government of Telangana vide Lr. No. Rc.No.779/2007/WL-1, dated 21.09.2020 for an amount of Rs. 388.214 Lakhs. NOC for operation of the mine with respective Siwaram Wild Life sanctuary will be obtained from NBWL. With afforestation on overburden dumps and proper management and development of greenbelt around the mine, the aesthetics is adopted and in the project area of 1927.13 ha about 1166.24 ha will be reclaimed with plantation on dumps, safe zone and other areas, 22.71 ha will be converted into agriculture area,120.31 ha will be left for public uses (Roads, infra and other structures), 376.93 ha will be undisturbed area and 240.94 ha will be left as water body at the end of the mine closure. 4.7 Impact on Socio Economic Environment In more than 130 years of coal mining in SCCL mining areas, no significant changes have been observed in the traditional way of life and occupation of the local people in coal mining areas. The local people are rather benefited due to the provision of more infrastructure facilities provided by the management. There are avenues for indirect employment facilities in the mine as well as other ancillary activities for the local people. As the present proposal is expansion of the existing underground mine to opencast cum underground mine by conversion of GDK No.5 underground mine to opencast mine and continuing production from GDK No.1&3 and GDK No.2&2A underground mines, the required manpower will be catered from the other mines of SCCL and also by direct employment if required. No villages/residential areas are present over the proposed project area. As such, there are no Project Displaced Families (PDFs). However, there is private land present in northeast and southeast part of the mine area. The Project Affected Families (PAFs) belonging to this private land are about 115. SCCL will continuously take up the infrastructure development works, provide medical facilities & education facilities, Skill development training to unemployed youth, recreation facilities under CSR policy of the company in the surroundings villages. Under CSR policy an amount of Rs. 16.48 crores were sent for various development activities in the RG-1 area. In addition, an amount of Rs.703.74 Crores has been deposited in the DMFT account of for carrying out various development activities in the surrounding villages. Further an amount of Rs. 2.87 Crores will be spent on various development activities in the surrounding effected villages within 3 years up to 2022-23 under Corporate Environmental Responsibility (CER) and under Community Resource Augmentation Plan of cluster of GDK No.1&3 incline, GDK No.2&2A and GDK No.5 Incline UG mines as this proposed cluster project is the expansion of the cluster of above three UG mines 5.0 ALTERNATIVES The present proposal is expansion of existing cluster of GDK No.1&3 incline, GDK No.2&2A and GDK No.5 incline mines from production capacity of 1.734 MTPA to 4.134 MTPA (5.134 MTPA peak) and increasing the Mine take area from 1356.85 ha to 1927.13ha in the name of cluster of Godavarikhani No.1&3 incline and Godavarikhani coal mine (No.2&2A and No.5). It is planned to enhance production by converting the Godavarikhani No.5 Incline underground mine into OC by utilizing the surface area of Godavarikhani No.2&2A underground mine for dumping of OB and continuing production of the coal from the Godavarikhani No.1&3 incline and Godavarikhani No.2&2A incline. The site is in close proximity to the existing mines of Ramagundam area-I, and as such transportation of infrastructure / technology for exploitation is easy. Economically viable in respect of investment and production. The coal mining projects which are site specific as per the allocation by the Ministry of Coal GOI, hence alternate sites were not considered.

GDK Coal Mine (No. 2 & 2A and No. 5): No villages/residential areas are present over the proposed project area of GDK Coal Mine (No.2&2A and No.5). As such, there are no Project Displaced Families (PDFs). However, there is private land present in northeast and southeast part of the mine area to be acquired. As per initial survey, Project Affected Families (PAFs) are 115 and cost of R&R is about ₹.6.96 Cr. The Rehabilitation & Resettlement will be provided to the PAFs (Project Affected Families) as per the provisions of the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act,2013 (LARR Act 2013). The PAFs are entitled for the Rehabilitation & Resettlement benefits as per the Act and Rules notified by State Govt and also as amended from time to time. All the major sons & daughters are treated as separate Family for the purpose of R&R benefits. Subsidence Management Plan The predicted surface subsidence, horizontal tensile strain and crack width are negligible for GDK 1&3, and GDK 2&2A Inclines. It is not likely to have any impact on surface structures. Hence, no subsidence management plan is being suggested. The mines under Cluster are presently operating underground mines in which the Bord and Pillar system of mining with hydraulic sand stowing is being practiced. GDK No.1&3 Incline will be operated for 57 years, GDK No. 2&2A Inclines will be operated for 15 years where as GDK No.5 Incline will be converted into OC. There are some important structures on the surface of GDK No.1&3 Incline. The predicted peak subsidence at the surface of GDK No. 1&3 Incline is 0.283 m and peak predicted horizontal tensile strain is 2.5 mm/m at the end of mining. There are no important structures on the surface of GDK No.2 and 2A incline. The predicted peak subsidence at the surface is less than 0.20 m and peak predicted horizontal tensile strain is 2.1 mm/m at the end of mining. One can safely conclude that the surface structures will not be affected by surface subsidence due to underground mining of GDKNo. 1&3 and GDK 2&2A Inclines. Risk assessment and Disaster Management Plan Mining and allied activities are associated with several potential hazards. A worker in a mine should be able to work under conditions which are adequately safe and healthy. At the same time, the environmental conditions should be such as not to impair his working efficiency. This is possible only when there is adequate safety in the mine. Being a open cast cum underground mine, the Hazards were identified based on the previous experience of open cast operations (shovel dumper combination) and

Underground operations (SDLs). Risk Assessment is to be performed on a regular basis. The goal for each risk assessment is to identify hazards, determine risk rating and controls and to review the implementation of risk controls from previous risk assessment sessions. The major risks associated with underground method in this mine are  Strata Problems  Inundation  Fire Hazard Hazards identified for the proposed Opencast working basing on the Tasks / Activities / Work places involved.  Extraction of Already Developed Coal Pillars.  Movement of HEMM  Drilling and Blasting Operations  Slope Stability  Inundation  Working near Faults Accordingly, a detailed risk assessment and disaster management plan has been prepared for the expansion basing the Technical Circulars issued by Directorate General of Mines Safety for implementing safety management systems in coal mines. 8.0 PROJECT BENEFITS The expected benefits from this expansion project are given below. • The project is expected to provide indirect employment opportunities to local people and improvement in communication, education, community development and medical facilities. • The project will help in socio-economic development of the area and also of the State. • The project helps in further development of infrastructure facilities that is beneficial to the local people. 9.0 ENVIRONMENTAL MANAGEMENT PLAN Environment Management Plan (EMP) aims at the preservation of ecological system by considering in-built pollution abatement facilities at the mining site. Mitigation measures at the source level and an overall environment management plan at the study area are elicited so as to improve the supportive capacity of the receiving bodies. The EMP aims at controlling pollution at the source level to the possible extent with the available and affordable technology followed by treatment before they are discharged. 9.1 Budgetary allocation for the Environment Protection Measures Adequate expenditure towards capital and recurring expenditure required for Environment Protection including for Environment Monitoring has been done by SCCL. In order to implement the environmental protection measures, a capital fund provision of Rs.19.94 Cr Crores has been provided in the project. In addition to this, a recurring cost of Rs.6.91 Crores per annum will also be spent on environmental management. The fund provision made towards various environment protection measures. 10.0 MINE CLOSURE PLAN Mining being a temporary venture must be closed after exhaustion of the minerals being exploited. Closing a mine without adequate planning of post mining activities may induce severe negative impacts on environment in the post closure stage. Closing of mining operations involves numerous issues like reclamation and environmental protection, community issues, socio-economic consideration, planning for alternate use of available facilities, cost estimation and asset disposal. The total mine closure cost to be deposited for the total life of the mine is estimated for Cluster of GDK 1&3 Incline and GDK Coal Mine (No.2&2A and No.5) is Rs.50.80 Crores

and Rs. 182.259 Crores respectively. The amount deposited till 2019-20 in the respective ESCROW accounts is Rs.1.075 Crores and Rs. 7.976 Crores. Monitoring of closure The monitoring of the mine closure plan is an essential requirement for review of the efficacy of the mine closure plan and to take corrective actions. Monitoring of quality of environmental attributes, such as air, water, land, soil will be continued during closure operations and 3/5 years after the closure at requisite locations as per the prescribed frequency, parameters and number of samples. 11.0 CONCLUSION The industrial and economic growth of India depends to a large extent on energy where coal plays a very important role as it is the prime source of energy for majority of power production units. The requirement of coal has significantly increased to meet the demand of the power sector. The other major requirement of coal comes from other industries like Cement, Sponge Iron, etc. The cluster of GDK No.1&3 Incline and GDK Coal Mine ( No.2&2A and No.5) opencast cum underground mine will have impacts on the local environment but with proper mitigation measures along with the effective implementation of the environment management measures as suggested in the EIA/EMP report and as recommended by MoEF&CC, CPCB and State Pollution Control Board, the negative impacts will be minimized to a great extent. However, development of this project has beneficial impact/effects in terms growth in regional economy, transform the region's economy from predominantly agricultural to significantly industrial, increase Government earnings and accelerate the pace of industrial development in the region. *****
