EXECUTIVE SUMMARY DRAFT ENVIRONMENT IMPACT ASSESSMENT STUDY For 7.316 ha of Piprahat Limestone Mine at Piprahat Village, Maihar Tehsil, Satna EESS District, Madhya Pradesh EEXECUTIVE SSUMMARY INTRODUCTION Environmental Impact Assessment (EIA) is a process, used to identify the environmental, social and economic impacts of a project prior to decision-making. It is a decision making tool, which guides the decision makers in taking appropriate decisions for proposed projects. EIA systematically examines both beneficial and adverse consequences of the proposed project and ensure that these impacts are taken into account during the project designing. IDENTIFICATION OF PROJECT PROPONENT M/s KJS Cement Ltd. is operating a Cement Plant near Amilia village in Maihar Taluka of Satna District in Madhya Pradesh. The plant has a production capacity of 1.5MTPA of Clinker and 2.25MTPA of Ordinary Portland Cement and blended cement. Part requirement of the plant will be met from this mine. The Mine is located near village Piprahat, Tehsil Maihar, District Satna, Madhya Pradesh over an area of 7.316 Ha. The lease area is mostly waste land and no forest land is involved in the mine lease area. The proposed capacity of the project is 5,00,000 TPA. Opencast Other Than Fully Mechanized (OTFM) mining method will be adopted. LOCATION The salient feature of the project is described in table below.

Ltd. MINING METHOD Opencast Other than fully mechanized method of mining will be adopted. All operation of mining such as development, winning of ore, loading and transport will be carried out by utilizing HEMM. No deep hole drilling and blasting of large diameter is proposed. While planning the proposal, economic depth of the pit for minimum degradation of land has been considered. In order to prevent haphazard excavation of pits, the development has been proposed at one place in quarry towards south. Working has been proposed in Quarry 1 of the ML area towards south. The working faces have been proposed to advance towards south. The OB removal has been proposed in 1 bench. The bench will be in OB soil. The height of the bench will be upto 3.0m and width of the bench will be 10m to 20m. Production will be carried out from benches in limestone. The height of bench will be 7 to 7.5 m and the width will be 15m. The haul road has been proposed at a gradient of minimum 1 in 16 and ramp 1 in 10. The OB soil and OB/waste generated will be simultaneously backfilled till end of mine. utilized as per proposal in Chapter 6. No labour camp is proposed within the applied area as mechanized mining has been proposed and all labours will be locally sourced. The transport of men is also not applicable and they will come from nearby villages. No tubs, haulage rope, conveyor or Project Proponent PROJECT CONSULTANT PAGE M/s K J S Cement Ltd.

The OB and ore will be excavated and loaded mechanically on dumpers to the dumping site. The year wise production plan is given in Table E-3.

Ltd. CONCEPTUAL WASTE MANAGEMENT Built up of dump during 1st to 3rd years - Dumping has been proposed towards south. During the proposal period two dumps will be created. The size of the dumps is as under - Soil Dump - 8,000 sqm x 10.0m OB/Waste Dump - 2,000 sqm x 6.0m The dumping will be done in one terrace. The sides will be sloped at angle of 28° for soil dump while 36° for waste dump. Quantum of waste dumping during 1st to 3rd years - During the ensuing SOM period 77,790 cum of soil and 17,398 cum of OB/waste will be generated which after swelling and compaction will correspond to 87,125 cum of soil and 19,485 cum of OB/waste. Out of this, 74,125 cum of soil and 7,960 cum of OB/waste will be stacked in the southern portion of ML area. The backfilling will commence the mined out area in northern side of the boundary. During the proposal period about 0.12 Ha of mined out area in north will be backfilled by 11,525 cum of OB/waste upto 10.0m height. Built up of dump at the conceptual stage - No dumping will be carried out during the plan period. Simultaneous backfilling will be carried during conceptual period. The old dumps will also be re-handled from 4th year onwards. The backfilling will be carried by putting coarser material first and then finer above it. Top soil to the thickness of 0.25m will be then spread and levelled. No dump will remain at end of mines. Quantum of waste dumping at the conceptual stage – 75,000cum of OB soil and 50,000cum of OB shale/ mine waste will be produced beyond the first 3 years period till the conceptual period. The total OB/waste generated will be simultaneously backfilled in excavated area during conceptual period. Protective measures proposed - Garland bund will be prepared all around the proposed water reservoir. Protective drain and bund will also be provided in the barrier zone. ANALYSIS OF ALTERNATIVES In the proposed project, opencast other than fully mechanized mining will be carried out. For that, no other methodology is going to be changed, depending upon the geological set up, strata of the rock, boulders and its structural behaviour. So, all the parameters of REIA/ EMP will be implemented as per the open cast other than fully mechanized mining. Project Proponent PROJECT CONSULTANT PAGE M/s K J S Cement Ltd.

An area of 10 km radius (aerial distance) from the boundary of the mine lease area is the study area for the EIA study. The study area has been divided into two zones viz core zone and buffer zone where core zone is the plant area and buffer zone is for study area excluding ML area. A detailed field monitoring study of the study area was carried out in Piprahat village for baseline environment assessment of the proposed mining area.
