EIA & EMP for Peak Capacity of Existing, Approved Gevra OCP (35.0 MTPA)

(EIA with Peak Capacity of 47.25 MTPA)

Application under clause 7(ii) of EIA Notification, 2006

1.0 INTRODUCTION

Gevra OCP is an operating mine under Gevra Area, South Eastern Coalfields Limited. The mine was expanded and given environment clearance for a capacity of 25 MTPA in October, 2004.

Further, the Environment Clearance for expansion of Gevra OCP from 25.0 to 35.0 MTPA was obtained on 3rd June, 2009. The environmental clearance for this project was issued vide letter No. J-11015/484/2007- IA. II (M) dt. 03.06.2009 from MOEF, Govt. of India.

Refer half yearly compliance report of conditions of Environmental Clearance attached with accompanying Form-I.

Gevra OCP has got the capability of producing coal by 35% higher than 35.0MTPA. The enhanced production is to meet the increased demand of power grade coal for the nation. In the preceding years, the coal production from Gevra OCP has been nearly 35 MTY.

1.1 Purpose of the report

This application is being made under clause 7(ii) of EIA Notification, 2006 for grant of prior Environmental Clearance (EC) for peak capacity of Gevra OCP of 47.25 MTPA considering the following points.

i. Liberation of power sector by Govt. of India has generated wide spread interests private & public sector investments in power generation and other industrial development. As such, there is an appreciable increase in the number of upcoming new projects as well as expansion of existing projects. The demand projection from SECL for the year 2012-13 is 269.07Mte. It will cater to the needs of upcoming industries like power, cement, fertilizers, other industries etc. The projected availability in the year 2012-13 is 117.00 Mte, resulting a shortage of 152.07 Mte. The demand projection from SECL for the year 2016 – 17 is 270.37 Mte. The projected availability in the year 2016 – 17 is 150.00 Mte. So, there will be a shortage of 120.37 Mte. For this purpose, Emergency Coal Production Plan of CIL has been formulated. Gevra Opencast has been identified as one of the project in the Emergency Coal Production Plan of CIL.

ii. The annual production of 35 Mt is being achieved for last three years fromthis property. Refer last three years production figure shown in table -1.1.

Sometimes with favorable geological conditions and improved productivity of the HEMM with better mining conditions project may produce upto 1.35 times of the planned capacity (peak).

Gevra OCP has got the capability of producing coal by 35% higher than 35 MTPA, with higher utilization of existing plant & machinery.

iii. The mine-able coal reserves are estimated to be 746.62 MT (as on 1.4.2013) and the corresponding overburden for Gevra OCP is estimated at 1125.726 Mcum (as on 1.4.2013). The average stripping ratio is 1.46 m3/T.If and when favorable geo-mining conditions exist, the project has an ability to produce an additional 35% coal, making the production of the project 47.25 MTPA.

iv. As the project will be a capacity enhancement of the existing Gevra OCP, the basic infrastructure is available and additional production can be planned with less gestation period.

v. All the additional 12.25 Mty production of Gevra OCP is proposed to be linked to KSTPS (Korba Super Thermal Power Station), other TPS (Thermal Power Stations), and industries. As such, there will not be any problem in marketing the coal from this project.

vi. The total leasehold area as per earlier approved EMP is 4184.486 Ha. The expansion of the project will be undertaken in two phases. In the first phase, mining will be done in an area of 4058.146 Ha. The remaining 126.341 Ha(NOC already obtained from the District Collector) will be acquired under the second phase of mining, bringing the area to a total of 4184.486 Ha.

vii. No change in technology is proposed.

viii.No change in backfilling & land reclamation programme will take place.

ix. The total permanent manpower is 3276 (3 shift working) and no additional manpower is involved.

x. Due to the increasing demand of coal for the nation, it is requested to consider the proposal for grant of environmental clearance from MOEF for peak capacity of 47.25 MTPA (from 35.0 MTPA normative capacity to Peak capacity of 47.25 MTPA, i.e. 35% incremental).

Therefore this project qualifies for EC under clause 7(ii) of EIA notification no.1533, Sep 2006, for approval of peak capacity production from 35 MTPA to 47.25 MTPA.

The mine block is drained by Laxman nalla flowing in a west-east direction and joins Aharan nadi, a tributary of Hasdeo River, at about 4.5km in NE from the mine. The other stream Kholar nala also a tributary of HasdeoRiver, controls the drainage in the northern part and whereas, Lilagar Nadi and Gangdel nala controls the south-west and south-east respectively. These streams, mostly perennial, behave as constant recharge sources. The pattern of drainage in the area is mostly dendritic in nature.

1.8 Description & importance of the Project to the country and region

South Eastern Coalfields Limited is facing increasing demand of coal because of increased demand from industry and power sector. Continuing and augmentation of coal production from the mines of SECL will help to bridge the gap of demand and supply of coal in India. To meet the growing demand of coal, especially in power and steel sectors, SECL has planned to increase its production capacity from the present production level of 113.837 MTPA by 2011-12 (end of XIth plan) and 145.00 MTPA by 2016-17 (end of XIIth plan).

Gevra Opencast Project will make available additional coal @ 12.25 MTPA apart from 35.0 MTPA that it is already producing, to meet the growing demand of non-coking coal.

2.0 PROJECT DESCRIPTION

2.1 Nature and size of the project

The project is a capacity enhancement of the existing Gevra opencast project. The project was expanded to 35.0 MTPA in 2009. Coal from Gevra OCP ismined by open-cast method. It is characterized by the presence of up to fouropen-castable seams with dip angles of 2°-6°. Seam thickness ranges from 1.10m to 45.23m. The thickest seam is Lower Kusmunda (19.28m-45.23m).Original mineable reserve was 975.00 Mt at average strip ratio of 1.27.

2.2 Quarry Parameters

The total quarry has been divided into three sections i.e. western section, central section and eastern section. It is proposed to mine all the three identified sections simultaneously. Mining operations however will be staggered between the sections. West and East sections will relatively lag and the central section will advance throughout the life of the mine.

2.3 Method of Mining

The selection of mining method for Gevra Opencast Expansion Project (35 Mty) has been based on the following factors:-

(i) Gevra Opencast Project is being worked by opencast methods deploying shovel dumper combination and HEMM configuration proposed in the sanctioned Project Report (35 Mty).

(ii) Present depth of workings is about 100 m against an ultimate planned depth of 220 m (as per sanctioned PR). Gevra Expansion Opencast Project has been planned upto a maximum depth of 318 m.

The coal deposit mainly constitutes of four thick coal seams occurring at shallow to moderate depth at favorable stripping ratio.

Based on the above factors, shovel-dumper combination is proposed to be continued. Deployment of draglines is not suggested as the combined thickness of the lower most seams i.e. LK seam (>48 m) will restrict the efficient deployment of dragline mining; and the inter-parting between LK (Top) and LK (Bottom) does not offer adequate load to justify the deployment. Moreover, coal in inter-parting will be lost. The present extent of workings indicates that most of the balance OB will be accommodated in the internal dumps. This will help to restore a part of the land during the course of mining operations.

CONFIGURATION OF EQUIPMENTS:

In the sanctioned Project Report (35 Mty), two combinations of equipment namely 42 cum capacity rope shovels & 240 T rear dumpers and 20 cum capacity rope shovels & 170 T rear dumpers were studied and discussed in details. It was decided to opt 42 cum capacity rope shovels & 240 T rear dumpers considering the following factors

1. The comparative economics is in favour of 42 cum rope shovels and 240 T rear dumpers combination.

2. The total number of shovels, dumpers, drills etc. is reduced, allowing concentration of working and easier traffic management. The same HEMM configuration is envisaged to continue in this proposed Project Report (25 to 35 Mty).

Excavation and transport of OB will be done departmentally by deploying existing equipment with additional 42 cum capacity rope shovels + 240 Trear dumpers and 9 cum capacity Hyd. Backhoe +100 T rear dumpers. Coal loading and transport operations will be done by leased HEMM with surface miner.


11

The top size of elect. rope shovels will have a nominal rated bucket capacity of 42cum Elect. Rope Shovels of this size will be used for excavation of waste material and will be largely restricted to the top OB above Seams including detrital mantle, and to the major parting between seams.

Overburden will need to be prepared for excavation by carrying out drilling and blasting operations. Coal will not require drilling, however, few drills have been provided in case of emergency for drilling. For OB preparation, 381 / 250 mm RBH drills are proposed.

The existing 410 HP dozers will be used for deployment in the mining benches and dump yards. Additional dozing requirement will be met by deploying 770-850HP dozers. The 275-320 HP class dozers will be replaced by higher size of dozers after survey-off on completion of the economic life span.

Major OB will be placed in the internal dumps after reconstruction of the mine. Progressive back-filling of worked out areas would be done by deposition of overburden in horizontal layers, some OB will also be required to be dumped in external dump.

A conveyor transport system for coal is proposed to be established. The conveyor will be laid on the floor of the bottom split of LK seam with future extensions of the conveyors also along the floor of this seam.

2.5 DRILLING & BLASTING

Drilling and blasting would be required only in OB bench before excavation by shovels. 381 mm RBH drills will be deployed for shovel benches of 42 cum rope shovel whereas 250 mm RBH drill will be deployed for benches of 12 cum shovels. Few 160 mm drills have been provided for coal also. 160 mm drills have been provided for drilling in benches of bands and partings. The explosives consumption has been envisaged as 0.30 - 0.35 kg/Mcum of excavation.

The ground vibration due to blasting can be controlled by :-

i) reducing the amount of explosives charged per delay,ii) reducing spacing and burden of blast holes,iii) reducing the amount of explosives charged per blast,iv) proper strata movement during blast by using suitable initiating

sequence.Since above parameters are site specific, the exact blasting pattern will be designed by conducting field trials.

2.6 O.B. DUMPS

The proposed sequence of mining is ideally suited for achieving the objective of placing maximum possible waste in the internal dumps. External dumps will be created mainly during the initial years of mine expansion. The proposed reconstruction of the mine gives best possible back-filling opportunity. Thus, external dump quantities will be minimized.

The opencast mining of Gevra block involves removal of 1267.00 M.cum. of overburden. Out of this only 147.60 M.cum. would be dumped as external dump and the balance 1119.40 M.cum. would be dumped into the de-coaled quarry.

Presently, internal backfilling is being done in the quarry and considerable volume of OB is also being dumped in the external dump. In coming years, major volume of OB will be internally backfilled and small volume of OB will continue to be dumped in the external dump.

The following design criteria have been considered for waste dumps.

(i) OB in external dumps will be stacked in 30 m high benches.(ii) OB in internal dumps will also be stacked in 30 m high benches.(iii) A berm width of 40 m has been provided for transport etc.(iv) Dump slope for each deck to be at natural angle of repose (37o).(v) Track dozers to be deployed for shaping the dumps.(vi) Final reclamation will be achieved using the equipment provided for

the purpose.The adopted mining and dumping strategy has enabled external dumps to be kept at bare minimum.

Final stage dumping and reclamation plan has been shown in plate – IX.

The analysis of the mine effluent and discharge water reveals that all physico-chemical parameters are within the limits prescribed by GSR 742(E) and for surface water quality all the values are found to be well within the permissible limit of IS: 2296 – 1982 for inland surface water (Class C) norms. Similarly, results of the ground water sample were compared with IS: 10500 and the parameters are within the limits.

3.3.1 Ground Water Status:

3.3.1.1 Ground water levels:

(a) Village groundwater levels:

In the area, monitoring in 39 wells has been covered under regular monitoring in the active open cast coal mining in Korba CF. The details of these monitoring wells and water levels monitored during Post-monsoon (November 2011) and Pre-monsoon period (May 2012) are given in Table-3.10.

The monitoring data reveal that the water levels, close to Gevra OCP during pre and post monsoon periods vary from 3.50 (Bhathapara (Hardi)) to 9.75m (Muriyanar) and 0.69m (Shakti Nagar (Gevra Basti)) to 8.0m (Raliya) respectively. In the buffer zone during pre and post monsoon the water level varies from 3.94m (Kherbhawana) to 10.77m (Nawagaon) and 0.6m (Bhalpahri) to 5.33m (Jhingatpur) respectively. The water table slopes towards south-east direction and maintain a uniform gradient.

The seasonal fluctuation between the pre monsoon and post monsoon water level close to Gevra OC varies from -0.13m (Katkidabri) to 7.00m (Muriyanar). In the buffer zone the seasonal fluctuation varies from 0.33m (Kherbhawana) to


21

7.53m (Pali). So, it implies that the water level fluctuation range is almost similar to the range of the water level fluctuation in the buffer zone.

To understand the impact of mining on local water levels, the water levels monitored during peak dry period (i.e. May 2012), in 39 wells located close to the active opencast mining (Dipka, Gevra, Kusmunda and Manikpur OCPs) area in Korba CF, were compared with the water levels of the corresponding period monitored 12 years earlier i.e. May 2000.

Among the 39 wells 15 wells are falling within the up dip area of the mines and remaining 24 wells are falling within the down dip area of the mines. In Fig. 2the wells situated in the up dip and down dip areas are marked in red coloredand the yellow colored columns respectively. The columns represent the rise and fall in the water level in May 2012 with respect to May 2000.

The water levels in 7 villages in the up dip area were lowered further and fluctuation varies from -2.56m (DW-29, Chunchuni) to -0.40m (DW-67, Dadar). Whereas in the balance 8 villages in the up dip area, there is a rise in water levels and was observed to vary from 0.05m (DW-96, Dhurena) to 3.35m (DW-107, Tiwarta). So, the overall water level fluctuation varies in the up dip area is -2.56m to 3.35m.

Similarly, incase of villages present in the down dip area of the mine, the water levels in 17 villages were lowered further and fluctuation varies from -2.60m (DW-82, Saraisingar) to -0.30m (DW-73, Karnala). Whereas in the balance 7 villages, there is a rise in water levels and was observed to vary from 0.15m (DW-72, Kurudih) to 2.20m (DW-48, Salora). So, the water level fluctuates between -2.60m to 2.20m in the down dip area.Hence, the fluctuation in ground water levels during 12 years period (May 2000 to May 2012) was observed to vary from -2.60m to +3.35m, with an average of -0.42m. (Table: 3.10 and Fig. 2). These variations may be attributed to the local utilisation and recharge conditions only. The fluctuations in water table are far below the acceptable decadal fall i.e. 4m/decade. Thus, the influence of mining on local water levels may be considered as negligible to marginal.

Rainfall (mm) Pre-Monsoon Post-Monsoon

The Pre and Post-monsoon trends of Hardi Bazaar reveals a declining trend mainly due to presence of large scale opencast mining activity close to the station, as well as increase in groundwater draft in the area by local people and considerable decline in rainfall.


26

At Banki Mogra station, both pre and post monsoon water levels reveal a declining trend. This may be attributed to the location of wells immediately above underground mine workings and large mine water pumping as well as increase in groundwater draft in the area by local people.

(d) Piezometers

In lines with the direction of MoEF, to observe the impact of mining on aquifer system, 6 number of piezometers were constructed in the area. All precautions were taken to protect these piezometers from local vandalism. Necessary cement sealing was provided in the deeper piezometers to differentiate the deeper and shallow aquifer. The finished diameter of these piezometers is 100mm. The piezometer sites were selected in close coordination with CGWB, Raipur. .The details and water levels of piezometers are given in Table 3.19.

(e) Water Quality:

In opencast mining, except for suspended solids, the mine water is free from any serious pollutants. With low sulphur content in coal, no acid mine drainage is anticipated. The quality of ground water in the study area was closely monitored during the study by CMPDI for the World Bank project and found that water is potable. As a part of Environment Management Plan (EMP) preparation, the surface, groundwater and mine water quality were monitored and found to be within the permissible standards.

Under routine environmental monitoring, the surface, groundwater and mine water quality, for all the operating mines in the area, have been monitored and found to be well within the permissible limits of stipulated standards. Mine water and other effluents have been treated before disposal and usage. The water quality management as adopted is shown in the following flowchart.

Figure 5 – Water quality management.

3.3.1.2 Groundwater Recharge Balance:

The net groundwater recharge, as estimated by rainfall infiltration method, and draft for the buffer zone were estimated as 67.97 M.Cum and 27.778 M.Cumrespectively. Thus, the balance available annual ground water recharge in the study area was assessed as 40.192 M.Cum. The detailed groundwater balance with recharge and discharge estimates are shown in the following pie diagram (Fig-6).

(M.Cum, %)

Figure 63.3.1.3 Radius of influence:

As mentioned earlier, because of the low permeability of aquifers, the impact of mining on local water regime will be marginal and the radius of influence will be limited to a small distance. So also, due to stratification, the individual permeable beds develop individual drawdown cones and the impact is usually limited to few hundred meters.

However, to estimate a probable zone of influence, dewatering of the entire unconfined aquifer was considered. As the permeability varies largely in the mine area, the radius of influence was estimated both with the existing (avg. 0.41 m/day) and the probable increase in permeability (2 m/day) due to the mining activities in the reclaimed area. As the Gevra, Dipka are the two adjacent mines, the cones will overlap along the common edge. The radius of influence (R) for the proposed and operating mines in the area, based on the Sichardt’s formula (R = C*(H-Hw)*K), were estimated as below:

1. Meteorologicalcondition

Coal dumps are susceptible to fire, and combustion may occur therein; hence there may be a likely change in ambient temperature, wind speed and direction to somewhat extent.

2. Ambient air quality

Type Impact

2.01 Direct Minimal increase in dust & noxious emission to the air owing to transport vehicles, Blasting, coal & dump handling causing to slight increase in the ambient SPM and CO levels.

2.02 Indirect Coal & dump handling & Workshop will generate indirect impact in the long run

2.03 Short term Drilling and Blasting may be attributed to slight increase in the ambient SPM and CO levels

2.04 Long term Coal handling, dump handling & Workshop will produce long term impact upon the air quality

4.1.3 Ambient Air Quality Impact Prediction Modeling by ISCST-3, USEPA

AAQ modeling based on ISCST-3, USEPA has been used for assessment of impact on ambient air quality at the monitoring stations termed as receptors, namely, A1, A2, A3, A4, A5 & A6 (Refer Plate V) due to peak production of 47.25 MTY for Gevra OCP Expansion. Refer AQIP out data in Section - C of EIA/EMP.This model basically determines the incremental PM10 in μg/m3 only on the receptor points due to mining with emission factors for its different activities such as transportation of coal & OB, Wind erosion, in-pit crushing, OB dumping, loading & unloading of coal at Railway Siding etc.The input parameters are tabulated vide page AQIM – 1 to 38. The Emission factors calculated based on different mining activities are tabulated at page AQIM-20. The entire quarry activities have been divided into four parts: WestPit, Central pit, internal OB dump 1 and internal OB dump 2. Coal transportation is done through conveyor belt system shown in the Plate – X as strips 2A to 2O and 4A – 4S. OB transportation is through roads termed as 1A-1F (west) and 3A-3B (central). The pits and Internal OB dumps have also been shown in Plate X.Volume for blasting of OB has been considered as (8m) x (7m) x (15m) Depth = 840 cum per blast. Blasting volume for coal has been considered as (6m) x (5m) x (7m) Depth = 210 cum.No. of blasting holes and blasted area per day have also been calculated (Page AQM-2).


32

The Emission factors (EF) were calculated for PM10 generation per day considering following activities:

For OB

1. Drilling -0.59 Kg/hole blasted2. Blasting -0.00022x(Area blasted)^1.5 kg3. Loading of OB -0.018 kg/te4. OB Unloading -0.001 kg/te5. OB Buldozing - 17 kg/hr6. OB transportation -2.25 kg/vehicle km travel7. Wind erosion -2.33 kg/HaFor Coal

4. Coal Buldozing – 53 kg/hr5. Coal transportation – 0.59 kg/V.Km Travel (Paved road)

- 2.25 kg/V.Km Travel (un paved road)6. In-pit crushing- 0.01 kg/te (primary) and 0.03 kg/te (secondary)7. Unloading point to bunker and chute to dumper -1.15 kg/te

Other aspects

1. There is no emission factor specified for Surface Miner as per USEPA hence no emission considered and water sprinkling is an integral part of the operation of surface miner.

2. 85% of coal winning will be through Surface Miner and balance 15% through drilling and blasting due to non operation oh surface miner at few places.

3 Only 24 Hourly Micro meteorological data in terms of Wind speed (m/s), direction (Angular, considering North as zero degree and for other directions moving clockwise from North). Wind temperature in (degree Kelvin), stability class and mixing height have been considered.

4 Emission reduction with the application of water-70% for transportation-50% for Pit activities-50% for Wind erosion

The Emission factors and the incremental values of (PM10) considered in the EIA/EMP for Gevra OCP (35 Mty to 47.25 Mty) at receptor points are tabulated below:

4.1.4 Ambient Air Quality Control Measures

Following air pollution control measures are and will be practiced within the mining area and at coal handling plants and railway siding site.

1. Mobile water sprinklers, 4 nos. of 28 KL, 6 nos. of 70 KL. And 1 no. 85 Te. Dumper converted into water tanker are used for dust suppression in mine haul roads along with 15 to 17 nos. of 9 KL. Capacity mobile water sprinklers used additionally on coal tipper roads for dust suppression.

2. Fixed/ Post type road side water sprinklers are arranged for dust suppression on haul roads and coal tipper roads.

3. Along the sides of the conveyor belts and at all transfer points, CHP, Silos and 30,000Te. ground bunker, water sprinkling arrangement is working effectively to suppress dust at source. At a few crushers/Feeder breakers and at the 5000 Te. Capacity ground bunker, mist spray water sprinklers are operating for dust control.

4. Dumpers and tippers are optimally loaded in order to prevent spillage on haul roads. Coal loaded vehicles are covered before leaving the mine premises.

5. Whenever the coal dust/slurry accumulates on haul roads and other roads in the mine premises, the same is cleared by the use of graders and loaders.

6. Dust extractors are working effectively in drills, thus reducing dust emissions at source.

7. Extensive plantation has been done and will continuously expanded in the future, thus acting as a dust and noise barrier between the mine and the residential areas.

8. Additionally, thick green belts have been developed around residential areas. Also, plantation is being done along the colony roads and around other mine infrastructures.

9. Employees are provided with LP gas connections, restricting combustion of coal for domestic purposes.

10. All approach roads to the mine and all other roads which are in regular use are topped. Internal roads & other permanent haul roads in side mine are WBM roads.

11. Presently, 100% coal production is being done by Surface Miner, which eliminates crushing & blasting of coal.

12. Coal transportation is being done by tippers. Installation of in pit conveyor system is going on for transportation of coal from mine pit to surface to reduce dust generation due to transportation.

13. Mine plans, to dispatch total coal mined to consumers by rail to reduce dust levels.

14. Till date about 38,52,183 nos of saplings have been planted on a total of615.820Ha. (327.30 Ha. Biologically reclaimed) of area for dust suppression. Till date approx expenditure incurred is 7.53 Crores. Details of plantation till date are given below in table – 4.5.

4.2.3 Control Measures for Water Pollution

A) Management of surface water drainage:-

Garland drains will be made around the periphery of the quarry. These garland drains will be connected to the local nalla which is not likely to be disturbed by mining operation. In the workings, heavy duty pumps will be deployed in rainy season which will throw the accumulated water from the working face after treatment into these garland drains. As the extraction of the quarry advances, the position of garland drain will also advance. Thus these garland drains will drain off the rain water away from the workings.

B) Mine Water Discharge & Industrial Effluent

1) Mine sump of 2.47 to 3.31 Mcum capacities will be established. 2) Settled mine effluent is being used for domestic & industrial consumption.3) Settling tank to treat mine water has been commissioned.4) Oil and grease trap is in operation for treating effluent water from HEMM

washing. After treatment, water is re-used for HEMM washing. This oil and grease trap is a ZERO DISCHARGE PLANT.

5) Mine sump will act as water recharge structure.6) Settling ponds are provided for treating the mine water discharge as well

as OB dump run-off.

C) Domestic Effluent Treatment:-

3.0 MLD capacity domestic effluent treatment plant for colony already commissioned to treat colony waste water of Gevra & Dipka projects.

D) Water Conservation: -

The waste water recycling after due treatment for the purpose mentioned above will enable conservation of water. Storage of conserved water in mine pits will be given due emphasis to provide water round the year and quality of water will be maintained before and after storage. Also, properly constructed storm water drains have been maintained in the colony.

E) Water Quality Monitoring:-

For complying with the statutory provision of MOEF and Pollution Control Board, fortnightly water quality is being monitored and evaluated. Corrective measures whenever needed are taken on the basis of monitoring results.

F) Construction and maintenance of Catch drains (11.5 Km. length) around the active mine is being done. Check dams have been provided additionally in the catch drains.

3. Proper preventive as well as corrective maintenance of HEMMs is being done in order to reduce the avoidable noise and vibrations.


38

4. Employees who are exposed to elevated levels of noise are provided with ear plugs.

5. Extensive plantation has been done on overburden dumps, which acts as a noise barrier between the mine and residential areas.

6. Additionally, thick green belts have been developed around residential areas. Also, plantation is being done along the colony roads and around other mine infrastructures.

7. At crushers/feeder breakers synthetic liners are fitted in the hoppers in order to reduce noise generation.

8. Shock tube initiation system of delay blasting is adopted for OB blasting in order to reduce blast induced noise and vibrations.

9. Introduction of surface miners has reduced the requirement for drilling and blasting operations and further crushing at in-pit and surface crushers, thus reducing the noise and vibration levels.

10.High capacity machines are to be deployed in the mining & transportation operations. These will ensure reduced number of vehicular trips, thereby reducing noise levels.

11.Lined chutes in Silo to reduce noise. 12.Regular monitoring of noise level of project area.

4.4 Land Use & Management4.4.1 Current Land Use: It is estimated that 4184.486* Ha. of land will be required

for Gevra Opencast Project (47.25 Mty as peak capacity) including land for quarry, external dumps, industrial and residential complex, road diversion, safety zone and rehabilitation colonies. (Refer - land use plan in Plate – V). The break-up of land use is given below and shown in Table- 4.10.

4.4.5 Socio-Economic Issues:

The project is located in a highly industrialized area of Korba district. A number of mines like Dipka OC, Kusmunda OC, Laxman OC and several underground mines of SECL and their colonies are situated in the study area. This has led to creation of social infrastructures like schools, hospitals, roads, DETP, etc which have helped in the economic development of the region. The project has already given a boost to the economy of the area by providing primary and secondary employment to local people. The infra-structural facilities provided by the project are benefitting local villagers also. The expansion of the project will further help in development of region through CSR activities and creation of direct and indirect employment.

4.4.6 Mine Closure Plan:

As per the guidelines of the MoC, the cost of the mine closure is to be computed based on the basis of the project area involved for the project.

In Gevra OC, the total project lease area involved is 4184.486 Ha. for mining, road, infrastructure, colony etc. So, the closure cost is to be computed considering a total area of 4184.486 Ha. Then, the mine closure cost would be 4184.486 X 6.00 = Rs. 25106.916 Lakhs as on august 2009 when wholesale price index was 129.60. This value will change according to wholesale price index during submission of the mine closure plan, such as;(Latest wholesale price index / wholesale price index as on august 2009 i.e. 129.60) X 6.00Lakh. Now, the present mine closure cost = (164.2 as wholesale price index for June. 2012 / 129.60) X 25106.916 = Rs. Lakhs.

So, The Final mine closure cost as on June - 2012 is Rs. 31,809.84 lakhs(Approx.) and at the end of mine life (i.e. on 22nd year), this closure cost will be escalated as Rs. 55674.76 Lakhs. Year wise escalation @ 5 % per year has been shown in table – 4.14.

4.4.6.1The detail of escrow account

The current value of corpus is Rs. 31,809.84 Lakhs (as on June-2012). Since, this is an ongoing project, the corpus is to be divided by balance life of mine i.e. 22 years (as of June 2012). So, the annual corpus comes to Rs. 1445.902 Lakhs (Approx.). This amount is to be deposited in escrow account every year with 5% escalation.

Environmental monitoring for three years after closure of mine will be carried out to evaluate the environmental quality of the area. If required, proper mitigation measures will be taken up after evaluating the environmental quality. The funds for this have been provided in the cost estimate. Before closure of the mine, Area GM will prepare survey and disposal report and the same will be submitted to DGMS for acceptance.

The mine closure activity is likely to significantly reduce the impact of industrial activity on the land apart from increasing the green cover and surface water availability.

All manpower in the role of SECL will be engaged in other projects of SECL till their superannuation. The people engaged in indirect employment / ancillary activities would find no financial loss due to the mine closure as their activities would be shifted in the new or expansion mines or industries located in the area.Moreover, before final mine closure, provision of vocational and skill development training to the affected persons due to mine closure, would be made for continuance / sustenance of income level.

Civic amenities will also be available as the infrastructure for same will be handed over after mine closure to State Government for future use of society.

5.0 Resettlement & Rehabilitation of PAPs

Rehabilitation & Rehabilitation is being done as per CIL Policy and employment is being provided to PAPs as per approved norms. A total of 968 families have already been rehabilitated by the Gevra project, details of which are provided in the compliance report of the previous Environmental clearance.

Out of the 18 villages for the rehabilitation and resettlement plan in the mine lease area, 7 villages (Bareli, Junadih, Mangaon, Kusmunda, Dhurena, Binjhara and Ghatmuda) have been rehabilitated/ resettled in the rehabilitation sites i.e. Vijay nagar, Ganga nagar, Nehru nagar, Yamuna nagar/ Laxman nagar. The rehabilitation and resettlement of 8 villages i.e. Pondi, Amagaon, Raliya (part), Bawanpat, Bithora, Naraibodh, Bhilai Bazar (part) and Gevra (part) are to be done on physical possession & displacement in rehabilitation sites such as Nehru nagar and Ganga nagar.

As per new R&R policy, most of the project affected persons (PAPs) are opting for a cash grant of Rs. 3.00 lakhs in lieu of the plot. As such approximately 10% to 20% persons will go to the rehabilitation sites under construction i.e. Nehru nagar and near y Ganga nagar in SECL acquired. The balance 3 villages under the acquired land of Gevra project, namely, Jhingatpur, Beltikari and Dipka, will not need to be rehabilitated by the Gevra project. Till date, a total of 2167 people, skilled as well as unskilled, have been displaced, given employment or paid compensation. The present R & R sites have been shown on land use plan enclosed in Plate – XII.


47

6.0 Corporate Social Responsibility/ Community Development

Coal India Limited amended its CSR Policy in December, 2009. As per new CSR Policy of CIL, the fund for CSR activities is proposed to be allocated from 5% of retained earnings of previous year subject to a minimum of Rs 5 / Tonne of coal production of previous year. The expenditure on CSR activities around the Project area is much higher than the earlier years. The population of this location and the local bodies including MP & MLA are involved in the implementation of CSR activities.

Corporate Social Responsibility (CSR) is taken up at Gevra Project level (Gevra Opencast Expansion OCP). Different villages falling in core zone and adjoining areas are benefited through CSR activities run at Area level. The nature of benefits include maintenance of ponds and community buildings, well digging and renovation, road repair, renovation of schools and construction of boundary wall, medical camps, water supply, skill development for employment generation etc. The sanctioned financial outgo on this head is Rs. 533.79 Lakhs for the financial year 2012-13. The expenditure on CSR & CD activities in Gevra Area in last five years is given below in table – 6.1 and details thereof are shown in Annexure – 15, accompanied with Form - I.

Table – 7.1

Sl. No.STATEMENT OF MAIN ISSUES

RAISED BY PUBLICREPLY/COMMENTS OF PROJECT PROPONENT

01 Land acquisition be done under the State Land Acquisition Rules and employment facilities be made available as per State R&R Policy.

Coal industry acquires land under CBA (A&D) Act of 1957. However, Rehabilitation and employment policy shall be adopted in consultation with Chattisgarh state government for the proposed expansion.

02 From all the pattadharis of the village, one employment has to be given according to their respective qualifications. The rehabilitation facilities should be provided as per Chattisgarh Govt. rehabilitation policy.

SECL, Gevra area shall adopt rehabilitation packages in consultation with Chattisgarh state government, hence eligibility of employment shall be governed by the said act.

03 In all the rehabilitation villages, necessary education facilities like primary & middle school should be provided as per govt. norms.

Educational facilities as per the R&R policy shall be followed in rehabilitation villages. SECL, Gevra area has in the past given due care to the educational need of the rehabilitated families by providing primary and secondary schools in the rehabilitation sites.

04 Due to expansion in production, there will be increase in dust pollution.

The project has been prepared in such a way the air pollution is minimized. The various measures adopted for the same are listed below:

1. Introduction of surface miner for coal production will eliminate the need for drilling, blasting & crushing i.e. the sources of generation of coal dust. The in-built water spraying system shall suppress any dust which might be generated during coal cutting.

2. Extensive use of belt conveyor (within mine area) for transportation of coal will reduce dust generation due to movement of coal tippers.

3. Introduction of 240 MT dumpers and 42 m3

shovels will reduce the number of trips of dumper carrying OB.

4. More water spraying arrangements and introduction of higher capacity water tankers for dust suppression in haul roads.

5. Plantation around quarry area wherever possible.05 Compensation of the land

should be minimum Rs. 5.00 Lakhs per acre.

SECL will procure land for proposed Gevra expansion project under the CBA (A&D) act 1957. Therefore land compensation will be made as per the stipulated guideline contained in the act. The compensation shall be made on the basis of fair market rate with 30% solatium at the time of making compensation OR the market rate of tha land prices at the time of the notification of the proposed land under section 4(i) of CBA (A&D) act with 30% soaltium, annual interest rates, escalation etc. as per the provisions of the act. The fair market price of the land shall be collected from the office of the Dy. Registrar, Katghora which is a state revenue dept.

06 SECL Gevra has violated the provision of EIA Notification 2006

SECL Gevra OCP had submitted application to the MoEF, New Delhi for environmental clearance to produce 35 MTY in august 2005 under the SO 942 (E) dt. 4.7.2005. The application is still pending with the MoEF. In the meantime, Government of India issued the EIA 2006 notification in September 2006 and the whole procedure of environmental clearance had to be complied with afresh. The project had complied with requirements to secure environmental clearance and hence there is no violation of environmental statutes.

It is worth mentioning that the Ministry of Coal, Govt. of India vide letter no. 43011-38(4) – 2005, dt. 4.5.2005 has already conveyed the approval of Hon’ble President of India regarding emergent increase in coal production by another 10 MT from Gevra OCP. To achieve the above target, SECL management has set a target of annual increase in coal production by 2 MT per year from Gevra OCP.

07 Due to expansion of Gevra OCP, nearby agricultural land will be affected.

Anticipating the adverse effect that might arise, the expansion project has already proposed a safety zone of width as per mining statutes between the limit of excavation and the acquired land.

08 SECL management shall provide free-of-cost medical facilities to all the affected villagers at SECL’s hospitals.

SECL Gevra area shall provide employment to eligible candidates along with their dependants being given free medical facilities. In addition to this, medical camps are conducted in nearby villages regularly where free medical treatment and medicines are provided to the people who need medical care.

09 Due to expansion, the ground water level will decrease in nearby villages which will create a shortage of drinking water.

To take care of the drinking water issues, SECL provides hand pumps and deep tube wells with pumps. During summer season, water tankers with drinking water are being supplied.

10 Due to expansion in production, there will be extreme traffic pressure for which the existing roads are not sufficient enough to cater to the same. It would be better to establish a separate road for coal transportation.

Gevra project will dispatch about 90% of its coal through rail to NTPC Korba and to different govt. power houses of various states including Gujarat, Rajasthan, Madhya Pradesh, Maharashtra etc. The remaining 10% of coal will be dispatched by road.

11 Due to blasting, cracks have developed in a number of houses. During the blasting operations, the mine management should adopt safe methods to prevent the effects of blasting.

In Gevra expansion project, it is proposed that the coal; will be produced by new technology i.e. by surface miner. By using this technology, Drilling, Blasting & crushing of coal will be totally eliminated. During blasting in OB,. All the safety instructions, & guidelines issued by the DGMS are strictly followed.

12 It is the question mark for the existence of EIA notification 2006, the mine capacity has been increased without

SECL Gevra OCP had submitted application to the MoEF, New Delhi for environmental clearance to produce 35 MTY in august 2005 under the SO 942 (E) dt. 4.7.2005. The application is still pending with the

MoEF. In the meantime, Government of India issued the EIA 2006 notification in September 2006 and the whole procedure of environmental clearance had to be complied with afresh. The project had complied with requirements to secure environmental clearance and hence there is no violation of environmental statutes.

It is worth mentioning that the Ministry of Coal, Govt. of India vide letter no. 43011-38(4) – 2005, dt. 4.5.2005 has already conveyed the approval of Hon’ble President of India regarding emergent increase in coal production by another 10 MT from Gevra OCP. To achieve the above target, SECL management has set a target of annual increase in coal production by 2 MT per year from Gevra OCP.

13 The employment & compensation should be provided first to the land oustees of Gevra project.

SECL Gevra area shall make compensation to land oustees once the land records are handed over to the Gevra area by the state government. The compensation shall be made as early as possible. For providing employment to the eligible land owners, immediate steps shall be taken for the applicants submitting all necessary required documents and papers. State authorities shall also be requested to identify the eligible applicants at the earliest as per norms and clear verification of employment applications from their side as soon as possible.

14 Electricity, water, medical and other facilities should be provided.

Electricity, water, medical and other facilities shall be provided by SECL, Gevra area al the rehabilitation sites, in consultation with the rehabilitation & resettlement policy of the state govt.

15 The roads are being damaged due to plying of over-loaded coal trucks and accidents are taking place.

Gevra project will dispatch about 90% of its coal through rail to NTPC Korba and to different govt. power houses of various states including Gujarat, Rajasthan, Madhya Pradesh, Maharashtra etc. Only the remaining 10% of coal will be dispatched by road. Hence, very less percentage of coal is being transported by road outside the mine acquired area. Also the trucks are loaded as per their carrying capacity declared by the RTO. Therefore the question of overloading the trucks by the Gevra project does not arise.

16 Rehabilitation policy is against the larger interest of the public.

Rehabilitation policy to be adopted as per the advice of State Govt. shall cater to the larger needs of the affected people.

17 Proper rehabilitation facilities are not being provided to the affected land oustees.

SECL Gevra area has started its activities nearly 25 to 26 years back and land oustees have been provided with resettlement and rehabilitation facilitiessubsequently at 3 rehabilitation sites i.e. Vijay nagar, Ganga nagar and Nehru nagar. The following facilities have been provided.

Tarred approach road, internal road, primary schools,

well, tube wells, community center, ponds, dispensary, electric poles with overhead wires, nullah & culvert, public stage, playground, bus-stop, weekly market etc.

In addition to the above, in the last 3 years, the several jobs have been taken up at the R&R sites as per the list enclosed.

Therefore, it can be established as a fact that SECL Gevra area has provided all the basic facilities at its rehabilitation sites. However, at present, rehabilitation and resettlement for proposed expansion shall be made in consultation with the state government.

18 What arrangements are being made by the management in order to protect the plantation?

The existing practice of afforestation is planting and maintenance of saplings through government of Chattisgarh undertaking i.e. CGRVVN for a period of 3 years.

19 Data provided by the management regarding plantation is incorrect.

As per the available records, the number of saplings planted since 1986 is 36.98 lakhs. The plantation job is being done by the state govt. organization i.e. state Van Vikas nigam with 3 years of maintenance. It is seen that societal pressure has resulted in depletion of planted trees by miscreants.

20 More and more plantation should be done.

Gevra area is aware of the necessity of plantation for the protection of environment. Therefore, every year plantation job is assigned to CGRVVN Ltd. Depending upon the availability of land, plantation is done and will also be carried out in the future.

21 For imparting the technical education to the villagers, technical institutes such as ITI etc. should be managed by the SECL management.

SECL as a whole has already taken up the issue of imparting technical education to the local people and as a result has donated a huge amount of money for the establishment of an engineering college at Korba.

22 05 nos. of fruit bearing plants should be provided at each house of the affected villages.

SECL Gevra area will certainly provide 05 nos. of fruit bearing trees to the willing families who will plant them in and around Gevra area.
