This chapter outlines the impacts and mitigation measures 5.1 Waste Generation & Disposal: Solid waste: Unusable solid waste generated will be in the ratio of 70:30 in the initial period The year wise waste generation during 5 years as follows: Year Table 5.1: Year Wise Waste Generation Waste Generation Recovery granite (M 3 ) (M 3 ) Total As the quarry is likely to continue further, waste generated will be dumped in quarry pits progressively by creating space for future dump storage in the quarry lease area. Contour plan of the mine area and details of working pits and dump areas are given at Annexure IV M/s. Pridhvi Envirotech (P) Ltd, Hyderabad 22

23 5.1.1 Waste Management Solid waste Site for waste dump: The lessee has purchased adjoining patta land of 0.64 ha in Sy Nos 306/1 in the SE & ha in Sy. No 306/3 in the East corner to the lease area for dumping the waste generated. Copy of the land documents of land proposed to be used for dumping the waste is enclosed at Annexure V Waste Generation estimated for entire lease period will be 40,450 M 3 Waste generation anticipated for 5 years period : 7,000 M 3 Dump Area: Area proposed for waste dump = ha or 8320 Sq.Mtrs Dump area will be cleared after filling the waste in the quarry pits at the end of the lease period. Management of dump Length of retaining wall will be 350 Mtrs covering 3 sides of the dump area Height of the retaining wall will be 40450/8320 = 5 Meters A retaining wall of height 5 M will be constructed along the 3 sides of the dump area. A Garland drain of length 350 Mtrs will be provided around the dump area. Utilization of solid waste: Utilization of waste generated is envisaged for civil construction works. Waste will be sold as aggregate or building construction material, back filling, road construction etc. Small blocks of 1 X 1 and 2 X 1 for tile plants and 4 cubes for poker stones will be religiously made out of such waste to salvage and generate revenue. Un utilized waste will be filled back in to the quarry pits. M/s. Pridhvi Envirotech (P) Ltd, Hyderabad 23

24 5.2 Impact on Flora and Fauna The lease area is a hillock without crops and not having any agricultural value. The hillock doesn t have any soil cover to support vegetation. There are no trees or wild plantation growth in the lease area. As such there is no impact on flora in the lease area. Green belt is developed along the buffer zone. Plant species like Neem, Siris, Sisham, Amaltas, Karanj, Jungle Jaledi, Eucalyptus & Kanju will be used to develop green belt. About 100 Saplings consisting of Neem, Teak will be planted per year along with the buffer zone & around waste dump area After the mining operations are over, waste dump will be used to fill the mine pits and develop greenery progressively. No wild life is reported from the area. Rabbits and snakes are reported to be present in the area. As such there is no impact on fauna. 5.3 Dust Generation during quarrying operation Dust is generated during drilling and quarrying operations. Following measures are proposed to reduce impact of dust in the surroundings Wet Drilling System Jackhammer are provided with wet Gunny bags Regular Sprinkling of Water on haul roads Greenbelt Development along the Buffer Zone of the Lease area, Haul roads & Waste Dumps 5.4 Dust generation from Roads during transportation Developing tree cover all along the road to reduce dust impact Regular spraying of water by water sprinkling system over haulage roads. Wetting the1.0 KM in village road from mine site M/s. Pridhvi Envirotech (P) Ltd, Hyderabad 24

25 Spraying water over the rock pile to be loaded to reduce dust generation during loading operation Sprinkling water at frequent intervals on the haul road to reduce dust generation during plying of dumpers. To reduce spread of dust, plantation will be developed along the mining lease boundary and haulage roads Periodic maintenance of haulage roads. Stabilizing over burden dumps with legumes and grass to prevent the erosion of soil and arrest the dust emission during windy days. 5.5 Silting of local water bodies As can be seen from base map there are no water bodies connecting to the site. Bahuda River is at about 9.0Km in the NE. Kestriya cheruvu is located close to the site as a seasonal pond and any possible run off can reach this pond and cause silting. In order to avoid any silting of the water body a garland canal is proposed al round the dump site which can contain washing away of any quarry waste during the rainy season 5.6 Vibrations and impact on local buildings & structures By using wire saw and excavators will minimize the effects so that the vibration generation will be feeble within 8 HZ Limit. There are no structures, buildings, habitation and any historical monuments within 1.0 KM of the site. Hence the impact will not be felt. In Sy. Nos 306/1, 3 already in the possession of the proponent for dumping the waste generated 5.7 Noise Sources and control measures The main sources of noise in mining activity are drilling, material handling machinery, loading equipment, etc. The noise generated by the machinery and vehicles as well as drilling operations will be minimal in the range of maximum 100 db M/s. Pridhvi Envirotech (P) Ltd, Hyderabad 25

26 Following mitigation measures would control noise pollution: Maintaining the machinery in good condition Providing earmuffs, ear plugs etc. to workers,, wherever the noise levels exceed 85 dba Properly lubricating all moving parts of machines Properly fastening non-moving parts of machines Developing thick greenbelt around the mining pit and along the haulage roads. Limiting the use of horns by the drivers of the vehicles M/s. Pridhvi Envirotech (P) Ltd, Hyderabad 26

27 6.0 POST CLOSURE PLAN & EMP COST ESTIMATES 6.1 Post Closure Plan Although the quarry operations were commenced in 2003 very little quarrying was done. Based on the mining plan activity, the quarrying operation can last up to 40 years. As per the sectional plan the mine depth may reach ground level and mine waste can be used to fill the mine progressively. Hence no additional foreign material is required. Green belt will be developed progressively on closed mine area which will improve overall environmental conditions. It is only after initial development/production & reduction of the altitude & making a dent in the area from below the ground level reclamation is proposed. However after attaining the ultimate depth & dimension laterally to be made available. For reclamation the pits will be developed in to a fish pond & rain water harvesting tank for the benefit of the nearby village. 6.2 Budget for Implementation Of EMP Following budget is proposed for implementation of EMP S.

28 6.3 Environmental Monitoring Plan Monitoring Strategy The monitoring of various environmental parameters is necessary and is a part and parcel of the environmental protection measures. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring. A well-defined environmental monitoring program would be employed with trained and qualified staff to monitor the ambient air as well as stack gas quality to check whether the quality of effluents is maintained within the permissible limits. A comprehensive monitoring program is suggested underneath. attributes should be monitored as given below: Environmental Air pollution Noise levels. Workers Health Locations and frequency of monitoring should be as per the guidelines of APPCB and MOEF. Ambient Air Monitoring As per MOEF there is a need to identify 3 ambient air stations at 120 o angle keeping the main source in the center. The ground level concentrations of suspended particulate, sulphur dioxide and nitrogen oxides in the ambient air outside the quarry boundaries will be monitored at regular intervals. Any deviation from predicted /expected values will be investigated and necessary action will be taken. Noise Monitoring Noise levels in the workspace environment will be monitored periodically. If any deviation is observed necessary corrective measures will be taken. Monitoring noise levels is essential to assess the efficacy of maintenance of schedules undertaken to reduce noise levels and noise protection measures. A good quality M/s.
