Sub:    Singhori Opencast Coal Mine Project (0.80 MTPA) of M/s Western Coalfields Ltd. (WCL), located near village Singhori, Tehsil Parseoni, District Nagpur, Maharashtra - Environmental clearance – reg.

Sir,

 

            This has reference to letter No. 43011/116/2006-CPAM dated 21.08.2006 of Ministry of Coal forwarding your application and letter of M/s Coal India Ltd. dated 28.09.2006 on the above-mentioned subject. The Ministry of Environment & Forests has considered your application. The proposal is for opening a new mine – Singhori Opencast project with a production of coal at 0.80 million tonnes per annum (MTPA) rated capacity in a total lease area of 428 ha. Of the total lease area, 406 ha consist of agricultural land, 16.50 ha of forestland and 5.50 ha is wasteland. There is no colony/township. Forestry clearance has been applied for. There area no National Parks, Wildlife Sanctuary, Biosphere Reserves found in the 10 km buffer zone. No endangered species are reported in the study area. Of the total lease area, area for excavation is 96.50 ha, 160 ha is for OB dumps, 6 ha is for infrastructure, 52 ha is for greenbelt 40 ha is safety berms, 32 ha is for diversion of nallah and 39.50 ha is rationalisation area. The mine is drained by a nallah which outflows into the River Kanhan. It is proposed to divert about 600m of the nallah which will be realigned at the final. An embankment is proposed to be made along the diverted nallah with a height difference of 6m from HFL. Project does not involve R&R. Mining will be opencast by mechanised method. The annual rated capacity of the mine is 0.80 MTPA of coal production. A CHP is proposed within the mine lease. Mineral transportation of 2425 TPD of coal is by road involving 480 10-T tippers from the CHP to Khaperkheda TPS located at a distance of 3 km. Ultimate working depth of the mine is 150 m bgl. Water table is in the range of 5.35 m – 16.15 m bgl in the core zone and 1.00m – 21m bgl in the buffer zone. Mining has intersected water table. Peak water requirement is 347 m3/d, which is to be met from mine pit water (285 m3/d) and from groundwater (62 m3/d). Of the total 66.73 Mm3 of OB generation including 2.4 Mm3 of topsoil, part of OB would be utilised in construction of embankment and the balance OB would be accumulated in one external OB dump of a maxm. of 60m height consisting of for stages of 15m each. Backfilling is not proposed due to steep geo-mining consideration and for future expansion. Life of the mine at the proposed rated capacity is 17 years. Public Hearing was held on 26.04.2005. NOC has been obtained on 19.01.2005. The project has been approved by M/s WCL on 27.03.2004 at a rated capacity of 0.80 MTPA. The capital cost of the extension project is Rs. 4871.61 lakhs.

 

2.         The Ministry of Environment & Forests hereby accords environmental clearance for the above-mentioned Singhori Opencast Coal Mine Project of M/s WCL for production of coal at 0.80 MTPA rated capacity involving a total lease area of 428 ha under the provisions of the Environmental Impact Assessment Notification, 2006 and subsequent amendments thereto and under Para 2.1.1 of MOEF Circular dated 13.10.2006 and subject to conditions specified below:
