Sub:       Ketki Underground Coal Mine Project (0.42 MTPA) of M/s South Eastern Coalfields Ltd. (SECL), located in village Ketka, Tehsil Surajpur, District Surguja, Chhattisgarh - environmental clearance – reg.

 

Sir,

 

                This has reference to Ministry of Coal’s letter No. 43011/83/2007-CPAM dated 06.06.2007 and forwarding your application on the aforesaid project and SECL’s subsequent letters dated 14.05.2008,  09.02.2009, 06.03.2009 and 01.04.2009 on the above-mentioned subject. The Ministry of Environment & Forests has considered the application.  It has been noted that the project is for opening a new coalmine -Ketki Underground Coalmine Project (UGP) of 0.42 MTPA rated capacity. The total lease area is 548.65 ha of which 314.98 ha is agricultural land, 221.95 ha and 11.72 ha of Govt. land. Forestry clearance has not been obtained. Of the total lease area, area for UG mining is 539.10 ha, 5ha of surface area is for infrastructure, 2.43 ha is for township and 1.50 ha si for miscellaneous uses. CHP is proposed within the ML area. There area no National Parks, Wildlife Sanctuary, Biosphere Reserves found in the 10 km buffer zone. A number of Reserve Forests are found in the buffer zone – Rajapur RF, Ketka RF, Dhawana RF. Jogba nala flows adjacent to lease boundary. The project does not involve modification of the natural drainage. Project does not involve R&R. Mining will be underground by semi-mechanised method. Mineral transportation of 1400 TPD of coal is by road. Ultimate working depth of the mine is 117m below ground level (bgl). Water table is in the range of 7.03-7.87m m during pre-monsoon and 2.51-2.63m bgl during post-monsoon. Average water requirement is 492 m3/d, which will be met from ground water (288 m3/d) and from mine water (204 m3/d). Public Hearing was held on 24.02.2006. Life of the mine at the rated capacity is 30 years. The project has been approved by M/s SECL on 08.04.2006. Capital cost of the project is Rs. 46.24 crores.

 

2.             The Ministry of Environment & forests hereby accords environmental clearance for the above-mentioned Ketki Underground Coal Mine Project of M/s SECL for production of coal at 0.42 MTPA rated capacity under the Environmental Impact Assessment Notification, 2006 and subsequent amendments and Circulars thereto subject to the compliance of the terms and conditions mentioned below:

 

A.            Specific Conditions

 

(i)            Sufficient coal pillars shall be left unextracted around the air shaft (within the subsidence influence area) to protect from any damage from subsidence, if any.

 

(ii)           Solid barriers shall be left below the roads falling within the blocks to avoid any damage to the roads.

(iii)         No depillaring operation shall be carried out below the township/colony.

 

(iv)          Depression due to subsidence resulting in water accumulating within the low lying areas shall be filled up or drained out by cutting drains.

 

(v)           While extracting panels in the lower seam, all water bodies in the subsidence area shall be drained. Dewatering of the old goaves of the upper seam shall be continued as long as the lower seam is worked to prevent accumulation of large water bodies over working area.

 

(vi)          Regular monitoring of subsidence movement on the surface over and around the working area and impact on natural drainage pattern, water bodies, vegetation, structure, roads, and surroundings shall be continued till movement ceases completely. In case of observation of any high rate of subsidence movement, appropriate effective corrective measures shall be taken to avoid loss of life and material. Cracks shall be effectively plugged with ballast and clayey soil/suitable material.

 

(vii)        Garland/surface drains (size, gradient and length) around the safety areas such as mine shaft and low lying areas and sump capacity shall be designed keeping 50% safety margin over an above the peak sudden rainfall and maximum discharge in the area adjoining the mine sites. Sump capacity shall also provided adequate retention period to allow proper settling of silt material. Sufficient number of pumps of adequate capacity shall be deployed to pump out mine water during peak rainfall.

 

(viii)       CHP shall be operated with high efficiency bag filters, water sprinkling system shall be provided to check fugitive emissions from crushing operations, conveyor system, haulage roads, transfer points, etc.

 

(ix)         Drills shall be wet operated only.

 

(x)          The major approach roads from ML used for mineral transportation shall be black topped and a 3-tier avenue plantation developed using a mix of native species.

 

(xi)         A progressive afforestation plan shall be prepared and implemented for the areas acquired and shall include areas along roads, infrastructure, township, CHP along ML boundary, etc, by planting native species in consultation with the local DFO/Agriculture Department. The density of the trees shall be around 2500 plants per ha.

 

(xii)        A Conservation Plan for endangered species found in and around the project area shall be formulated and implemented  in consultation with the State Forest and Wildlife Departments. A Conservatory shall be established and the rare and endangered including medicinal plants species, identified through a pre-mining survey, shall be conserved during the life of the project. A budgetary provision shall be earmarked for its establishment and maintenance and a report thereon submitted as part of the Monitoring Report.

 

(xiii)      Regular monitoring of groundwater level and quality shall be carried out by establishing a network of exiting wells and construction of new peizometers. The monitoring for quantity shall be done four times a year in pre-monsoon (May), monsoon (August), post-monsoon (November) and winter (January) seasons and for quality in May. Data thus collected shall be submitted to the Ministry of Environment & Forests and to the Central Pollution Control Board quarterly within one month of monitoring.

 

(xiv)       The Company shall use treated mine water for its mine operations. Use of borewell water for mining operations shall be avoided. The company shall obtain approval of CGWA/CGWB Regional Office for use of groundwater if any, for mining operations.
