Requirement of power supply and its source 20. Requirement of water supply and its source Electric power shall not require for operations. Approx. 50 lit/d High Speed Diesel will be require for running of drilling machinery and blasting operations. Approx. 5.0 KLPD water will require for drinking, plantation and sprinkling purpose Source: Tanker. 21. Type of mining (Manual / Semimechanized / Mechanised). Semi Mechanized Open cast 22. Equipments to be used Bulldozers, Four Wheeled Trolley attached to tractor / Truck. (bulldozers, hydraulic excavators, JCB, scrapers, loaders, etc.) 23. Details of method of working with phasing of activities (sequence of mining operations) Mining in general will be carried out by forming benches up to 2.0 to 3.0 m height. Excavated Run of Mine (ROM) will be subjected to manual sizing into fraction of +25 mm to 100 mm. The yield of sized black trap will be around 85%, undersize limestone will be around 10% and remaining 5% as mining losses. Mining losses are on account of dust generation during drilling / blasting, wash off from the area This sized black trap will be loaded into trucks manually and dispatched to the stone crushing plant. Remaining 10% of undersize material will be stacked on the worked out pit floor. Drilling and blasting will be also carried out by using air compressor and drill machine / jack hammer drill. Four Wheeled Trolley attached to tractor will be generally used for movement of mineral. The mineral transported out of the lease hold will be with the help of tippers and trucks. All pit working will be securely fenced as per the standards prescribed by DGMS. Approach roads to pit faces shall be maintained as required. The black trap being medium hard category requires some drilling and blasting for excavation.

3 Sr. Details To maintain a bench height of 3 meters, drilling by drill machine is recommended. However in future effort will be made to improve upon it. The frequency of blasting will be based on requirement of ROM/Sized black trap. Benches shall be kept sloped at an angle of 15 from the vertical (i.e. 75 from the horizontal). Same angle of slope shall be maintained for drill /blast holes also. With 3 m high benches, sloped at an angle of 15 to vertical, the bench slope height shall be 3.1 m and with sub-grade drilling of 0.2 m. The depth of shot holes to be drilled shall be 3.3 m. For every hole, one delay detonator would be used. Blasting would be done by using short delay action detonators to reduce ground vibration. Holes would be connected in a row in series and the rows in parallel, i.e. Series Parallel connection would be made at the time of blasting. Double row blasting would be preferred to single row so as to cut down on the number of blasts required for maintaining production. 24. Explosives, detonators to be used ANFO, slurry, emulsion 25. Details of drilling, blasting Drilling will be carried out by using drill machine. The blasting activity is Existing to be carried out during day time. The frequency of blasting will be based on requirement of Run of Mine (ROM)/black trap Sized. For every hole, one delay detonator would be used. Blasting would be done by using short delay action detonators to reduce ground vibration. Holes would be connected in a row in series and the rows in parallel, i.e. Series parallel connection would be made at the time of blasting. Double row blasting would be preferred to single row so as to cut down on the number of blasts required for maintaining production. Various types of explosives such as ANFO, slurry, emulsion etc. will be used for blasting. Since ANFO is cheaper and economical, it will be used as much as possible except in rainy season. Delay detonators or Nonel detonating fuse will be used since multi row system of firing will be carried out so as to reduce the ground vibration, noise, fly rock etc. due to blasting. Sequential blasting techniques using sequential blasting machine shall be used to reduce explosive charge per delay to a minimum to reduce ground vibration. 26. Safety measures at the time of blasting Entry of unauthorized persons will be prohibited. Fire fighting and first-aid provisions in the mines office complex and mining area. Provisions of all the safety appliances such as safety boot, helmets, goggles etc. will be made available to the employees and regular check for their use. Handling of explosives, charging and blasting will be carried out by competent persons only. 27. Details of Over Burden (OB) removal and stacking Over Burden will be stacked separately and temporarily for ultimate dispose off by means of backfilling and also for covering the mine area. The average thickness of the overburden is around 2.00 to 3.00 meters. In the Existing mine waste will be overburden in the form of weathered mantle which inclusive of top soil layer. Half meter average thickness of top soil has been considered for separate removal and stacking for use in mine reclamation later. It shall be used for refilling of low lying area or for paving roads. 28. Height and width of benches and side slope Benches shall be kept sloped at an angle of 15 from the vertical (i.e. 75 from the horizontal). Same angle of slope shall be maintained for drill /blast holes also. With 3 m high benches, sloped at an angle of 15 to vertical, the bench slope height shall be 3.1 m and with sub-grade drilling of 0.2 m. The depth of shot holes to be drilled shall be 3.3 m. 29.

Time of working hours in a day 8.00 am to 6.00 pm ENVIRONMENTAL MANAGAMENT PLAN 35. Measures Existing for protection Please refer Annexure 1 (Environment Management Plan) of environmental attributes like land, water, air, human health, etc. 36. Measures for control of noise, vibration and fly rock problems due to blasting Controlled blasting with proper spacing, burden and stemming will be maintained. Muffling or covering of blast holes properly before blasting, is the common solution to prevent fly rock from damaging human habitants and structures. Generally, mat or mesh (40 mm X 40 mm size) made of preferably of locally available steel ropes (5 to 6 mm) are used for muffling purpose. Sand bags weighing 40 to 50 kg are kept over the mesh at an interval of 3 m. The blasting shall be carried out during favorable atmospheric condition and less human activity timings. Reducing the exposure time of workers to the higher noise levels. Secondary blasting and pop shooting will be totally avoided.

6 INTRODUCTION Annexure - 1 ENVIRONMENT MANAGEMENT PLAN The Environment Management Plan (EMP) is required to ensure sustainable development in the area of the Existing project. Hence it needs to be an all encompass plan for which the industry, Government, Regulating agencies like Pollution Control Board working in the region and more importantly the population of the area need to extend their co-operation and contribution. It has been evaluated that the project area will not be affected significantly with Existing project. Mitigation measures at the source level and an overall Management Plan at the site level are elicited so as to improve the surrounding environment. The following mitigation measures are recommended in order to synchronize the economic development of the project area with the environmental protection of the region. In the mining phase the environmental impacts are due to continuous operation of the project, hence, the emphasis in the Environment Management Plan (EMP) is to minimize such impacts. The emphasis on the EMP development is on the following: Mitigation measures for each of the activities causing the environmental impact Monitoring plans for checking activities and environmental parameters and Monitoring responsibilities Role responsibilities and resource allocation for monitoring MITIGATION MEASURES Each of the activities during mining phase is critically reviewed for suggestion of mitigation measures. Based on this the Table-1 gives the mitigation measures for the activities considered to be causing significant environmental impacts during mining phase. Following sections describes the environment management plan Existing for stone mining. 6
