9 Water Environment: M/s. Southern Rocks & Minerals (P) Limited (Ext Ha) There is no water streams flowing through the mine hence impact on surface runoff is not envisaged. During mining operation runoff will be collected in pit and will be used for mining operations like wetting of haul roads etc. During operation of mine 8.0 KLD of water is required which will be used for domestic consumption, wetting of haul roads, green belt development and wire saw cutting 3.0 ENVIRONMENTAL MANAGEMENT PLAN (EMP) 3.1 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES Open cast colour granite quarrying will not result in some adverse impacts on the surrounding environment and the magnitude and impact of the environmental pollution depends on method of mining, scale and concentration of mining activity. The following are the possible impacts while carrying out the quarrying activities. Change in land use pattern Waste generation Impact on flora & fauna around quarry site. Dust generation during quarrying and transportation Silting of local water bodies due to soil erosion Vibrations and impact on surroundings Noise from quarrying operations. However the above impacts can be mitigated with proper Environmental Management Plan supported by adequate financial allocation. 3.2 WASTE GENERATION Liquid Waste: The liquid waste will be mainly run of rain water during monsoon months from the quarry face. The rain water draining the exposed rocks, fragment and dust in the quarry is susceptible for incorporating the above as suspended solids into the run Page 9 of 16

10 off. Seepage of such water down to the water table may cause pollution to the ground water. However there is no scope for run off rain waste, as the quarrying is carried out in already quarried pit. Only rain water will be collected in the quarry pit. Very small quantity of waste water will be generated from domestic consumption. 3.3 WASTE MANAGEMENT: Solid waste: It is proposed to produce M 3 of waste is generated during the five years period. It consist of Granite Blocks of various sizes, shapes and dimension. Soil component will be minimal but will be stocked separately from the mine waste. Liquid Waste: The Liquid waste includes runoff water during monsoon months from the quarry and waste dumps. The rain draining the freshly exposed Rocks Fragments and dust in the quarry and dump is susceptible for inculpating suspended solids and toxic elements. Such water laden with suspended solids may effect the fertility of the soil in the agricultural land as well as result in the formation of silt blankets on the warm bodies. The slit content may reach the major rivers in the region. Seepage of such water down to the water Table may cause pollution to the Ground water. In order to avoid this it would be necessary to make the water leaving the Quarry and dump site silt free. Since granite is free from such Minerals, which contribute toxic. The silt leaving the quarry can be arrested by constructing check dams at points where the water leaves the Quarry. Siltation tanks can also be constructed so that silt is trapped in them. The water leaving the dumps shall also be constructed so that silt is trapped in them. The water leaving the dumps shall also be made silt free by constructing garland canal along the base of the dump. Page 10 of 16

11 3.4 AIR POLLUTION Dust Generation during quarrying operation and transportation Dust will be generated during the quarry operation and handling, which needs to be controlled to mitigate the pollution. Hence dust will be generated during movement of transportation vehicles. The following measures are proposed to mitigate pollution due to dust emissions. Developing tree cover all along the road to reduce dust impact Sprinkling water at frequent intervals on the haul road to reduce dust generation during plying of dumpers. Periodic maintenance of haulage roads. Spraying water over the ROM to be loaded to reduce dust generation during loading operation. Developing plantation along the mining lease boundary and haulage roads to reduce spread of dust. Green Belt Development Plan Green belt is proposed to be developed in the buffer zone and other vacant area on the bunds formed with top soil removed during the quarrying for mitigating the air pollution due to fugitive dust emissions and the noise generated, if any, due to blasting. Native species like Neem, Sargudu, Mango, Pungemia, Eucalyptus etc will be planted. 3.5 IMPACT ON FLORA AND FAUNA Vegetation in the area is moderate and is mainly in the form of thorny bushes, small shrubs and some tress. On the other hand green belt is proposed to be developed along the buffer zone. Plant species like Neem, Mango & Eucalyptus will be used to develop green belt. 3.6 VIBRATIONS AND IMPACT Ground vibrations may occur during quarrying operations. Effective measures will be undertaken to prevent the vibrations. Page 11 of 16

12 As the nearest habitation is Chitteyyapalem village at distance of 1.12 kms from the quarry site, there will not be any impact on buildings or structures as well as local beings due to this mining. 3.7 NOISE SOURCESS 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 100dB. Following mitigation measures would control noise pollution: Maintaining the machinery in good condition by properly lubricating all moving parts. Providing earmuffs, ear plugs etc. to workers. Using Hydraulic drills for drilling. Designing and following the controlled blasting techniques in such a way that only one holes should blast at a time by using non-electrical delay detonators for sequential blasting. Conventional mining methods will be implemented instead of blasting, line drilling for splitting or chemical powder, wire saw cutting, hydraulic drilling etc. Avoiding secondary blasting by using rock breakers. Developing thick greenbelt around the mining pit and along the haulage roads. Limiting the use of horns by the drivers of the vehicles. 3.8 RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN The major risks associated with quarrying are drilling risks, slope failure; fly rocks and vibration due to blasting, storage of explosives, toxic fumes from blasting etc. Risk analysis involves systematic identification and assessment of major damage potential credible risk scenario to help management to make objective decisions on hazards reduction or avoidance measures meeting regulatory requirements and develop a structured management framework for an effective Disaster Management Plan including emergency preparedness and contingency plans. Page 12 of 16

13 The planning for mitigating the emergency involves reorganization the accident or possible, assessing the consequences of such possible accident sand deciding on emergency planning/procedures in advance. Both on site & off site that would be necessary to be implemented in the event of emergency without any delay and confusion. Proper bench design in mines and observing safety measures for transportation storage, handling of explosives & fuels, etc, good maintenance of vehicles, roads, and fire prevention measures shall go in preventing disaster/accidents. Mining shall be carried out as per MMR 1961 & rules and regulations applicable. The project in charge is having a mobile communication for quick intimation of information if need arises. As the quarry operation is open cast, only possible risk is collapse of quarry/ pit sides when people are working. For this proper bench slope will be maintained as per the mining plan. Mining operation will not be conducted during rainy days to avoid any collapse of the overburden into mine pit. All precautions would be taken to control fly rock during the blasting operations. The quarry area is to be provided with good communication facilities like telephone & mobile phone. In case of any minor/major accidents within the mine, the same will be communicated to local revenue officials, police, fire Department, DGMS etc for action. A vehicle is kept all the time at the quarry site for conveyance. The workmen in the project are periodically trained at group vocational training center for proper safety training as per the DGMS circulars. At quarry level first aid facility is provided and person(s) will be shifted to nearest major hospital. Page 13 of 16

14 A key person will be assigned duties and responsibilities for incident response and emergency response at the quarry. At mine level first aid will provide and person shall be shifted to nearby government hospital, having all basic facilities and qualified medical officer who is capable of handling normal accidents. Quarry manager is the person responsible of the disaster management and he need to be contacted in case of any disaster. 3.9 OCCUPATIONAL HEALTH & SAFETY As a measure of occupational safety & health, the following facilities will be provided to the workmen; Providing Dust masks to prevent exposure to dust Providing ear muffs/ear plugs for protecting from adverse affects of noise Monitoring the health of the workers on regular basis Periodical Medical Examination (PME) as per Mines Rules Providing First Aid Facility at the site. Providing basic amenities to the quarry workmen BUDGETS FOR IMPELEMENTATION OF EMP The Environmental Management plan involves: Dust Suppression measures Green Belt Development, Undertaking periodical Environmental monitoring Providing personal protective equipments 3.11 ENVIRONMENTAL MONITORING PLAN Monitoring Strategy The monitoring of various environmental parameters is necessary and is a part of the environmental protection measures. Monitoring is as important as that of controlling, since the efficiency of control measures can only be determined by monitoring. Page 14 of 16

15 A well-defined environmental monitoring program would be taken up to monitor the ambient air to check whether the quality of air is maintained within the permissible limits. The following environmental attributes should be monitored: Air pollution. Noise pollution Workers Health Locations and frequency of monitoring should be as per the guide lines of APPCB and MOEF. AMBIENT AIR MONITORING The ground level concentrations of suspended particulate (PM 10 & PM 2.5, ), sulphur dioxide SO 2 AND Nitrogen Oxide (NO X ) in the ambient air outside the quarry boundaries shall be monitored at regular intervals. Any deviation from predicted /expected values shall be investigated and necessary action be taken. NOISE MONITORING Noise levels in the work space environment will be monitored periodically. If any deviation is observed necessary corruptive 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 sound pressure level meter is essential for this purpose. This work can be handled by out sourcing the surveillance is for the benefit of the workers will being and to keep track of machine wear. WORKERS HEALTH Regular health check up of workers will be carried out at the nearest hospital. Page 15 of 16

16 3.12 POST CLOSURE PLAN Based on the estimation of mineable reserves in the mining plan, the quarrying operations will be continued at least 20 years further reserves may be proved within the Mining Plan period. At the end of the lease period, after completion of the quarrying, the quarry pits would be developed as reservoirs for rain water Collection, which act as sources for recharging the ground water levels in the area. Green belt will be developed on the bunds of the quarry and along the haulage roads. 4.0 CONCLUSION: The Colour Granite project proposed by M/s. Southern Rocks & Minerals (P) Limited G.P.A. Holder : Ch.Rama Rao proposed to obtain a mining lease for color granite over an Extent of which is located in Sy. No: 397 (Carved from 233) of Rajam Village, Butchayyapeta Mandal, Visakhapatnam District, Andhra Pradesh will be environmental compatible to the surrounding and there will be no long term environmental impact based on the existing environmental scenario. The particulate matter getting airborne from the quarrying activity gets dispersed in close proximity itself and settles down early. The noise levels due to the proposed quarry activity are also not of a higher order that calls for immediate corrective measures. There will be positive socio-economic front in the surrounding region due to the proposed quarrying activity. The green belt development would help in achieving ecological balance. Environmental Management Plan (EMP) will help mitigate adverse impacts on the environment. Where impacts occur, immediate action would be taken to reduce the escalation of effects associated with these impacts. Hence, it is requested that Environmental Clearance be accorded to the color granite project. Page 16 of 16
