xii.xiii.xiv.xv.xvi.xvii.crore. Environmental Management Cost is Rs. 62.2 crore.Approvals: Applied for Ground water clearance. The Mine Closure approval obtained on24.01.2012. Date of approval of mine plan is 24.01.2012. Board’s approval obtained on24.01.2012.Wildlife issues: There are no national Parks, wildlife sanctuary, biosphere reserves foundin the 10 km buffer zone.Forestry issues: Total forest area involved for mining 316.62 ha. Extent of forest land inthe project is 316.62 Ha.Total afforestation plan shall be implemented covering an area of 734.16 ha at the end ofmining where reclaimed external OB dump is 72.28 Ha and Internal OB Dump 380.72 ha.Green Belt over an area of 188.17 ha. Density of tree plantation 2500 trees/ ha of plants.There are no court cases/violation pending with the project proponent.Certificate of compliance of earlier EC from MoEF, Regional office, Bhubaneswar hasbeen issued vide their letter no. dtd. 18.07.2013.2.11.3 The proposal was last considered in the 47 th EAC meeting held on 23 rd -24 th April, 2012. TheCommittee desired that proponent may re-examine the location of the proposed washery andthe CHP nearer to the mine towards the southern side of the ML. The Committee also desiredthat the proponent examine storing the OB in a temporary external OB dump(s) in themineralised area of the ML. The Committee also observed that the CCL colony would bebetween the two proposed external OB dumps and desired that the location of the external OBdumps on both sides of the colony, transport of coal, location of washery and railway sidingrequires re-examination. The Committee also desired that the water bodies and river andsurface drainage should not be disturbed and an embankment between the water bodies andmine operations should be provided. The Committee desired that a three-stage settlingtank/pond should be established for settling the suspended solids. The Committee desired thatthe 90m dump height with ultimate slope of 280 should be calculated from the toe of thedump to the river bed to avoid collapse of OB dump in future due to mine seepage. The heightof OB dump should also be reduced to 70m. The Committee desired that the satellite map anddigital map National Remote Sensing Centre (NRSC) of the whole ML area should beprovided.2.11.4 The proponent has further informed that:i. The external OB dump and location of washery and CHP have been revised. Thedumper travel distance upto CHP would be reduced to 300 m from 1400 m. Thesouthern part of the mine lease area is coal bearing, which has been /is proposed tobe included in quarry area of the adjacent coal blocks. As the coal evacuation isproposed from mine entry in the north of quarry, the coal transportation lead will bemore in case the proposed washery and the CHP is located towards the southernside of the ML. Therefore it is not suitable to locate the proposed washery and theCHP nearer to the mine towards the southern side of the ML.ii. The OB dumping in internal dumps (demineralised/de-coaled areas) is proposed toits maximum extent. Only 11% of OB is proposed to be dumped externallypreferably on non-coal bearing area. Relocating the external OB dumps in themineralised area (in coal bearing are) of the ML (Particularly in the south –sideadjoining blocks) will not only hamper their future development, but also increasethe OB transport lead.iii. With revised layout of mine infrastructure, the minimum distances of the proposedwashery, CHP and external OB dump from the existing CCl colony will be around550 m, 600 m & 200 m respectively. It is proposed to develop 3 tier plantations allalong the periphery of the colony for dust and noise attenuation. This will protectthe colony from air and noise pollution.iv. Bakaro River flows along east of the lease boundary and no change in its drainage isproposed. An embankment of 1.7 km length along Bokaro River is proposed to beconstructed. One seasonal nala, flows along North-Western side of Quarry-2 at aMoM_ 2 nd EAC_Oct201323
