The nearest Town Kanigiri is situated at 37.0 Km in NNE direction from the lease area. Amenities like post & telegraph office, police station, primary health centre etc. are available in all the villages. Water are available at the nearby villages and in nearby agricultural bore wells. Power connection is available at nearby villages. Agriculture is important occupation of the local people.

3 3. GEOLOGY 3.1 Topography: The area surrounding the quartz deposit is free from vegetation and exposures of country rock are exposed around the quartz deposit. Overall height of quartz deposit is 9 M (lowest contour is 100 M and highest contour is 109 M) within the quarry least area. The vegetation of local areacomprises small bushes and thorny trees. Agriculture lands are located due North of quarry lease area, whereas the Grazing lands are in South, West and East. 3.2 Regional Geology: The area underlain by Migmatised - Quartz - Felspathic Gneiss and Quartz, Biotite - Muscovite Garnet Schist. They occur as synform in which garnet is developed in central part, while kyanite and staurolite in the peripheral zones, both of these formations are extensively invaded by Pegmatite and Quartz veins. The general trend of the formation is NNW-SSE to NW-SW with moderate dips on either side. The rock types in these are folded with 3 phases of folding showing some tightly appressed isoclinal and some beds are tightly folded with bedding and schistosity on the surface. Intrusive pegmatite are found in a limbs of the folds, intruded concordantly with the foliation of schist and occurs as discrete or connected lenses, veins and stringers and arranged in enechelon pattern. Schist enclaves have also been noticed in many pegmatite veins. Quartz Vein - (Reef type elongated intrusive body) Lower Dharwars - Chloritic and MicaceousSchists. Oldest Archeaens - Igneous rocks like Granites and Gneisses 3.3 Local Geology The Quartz is formed in two discontinuous veins in the subject area within the host rock. The Quartz veins are trending in NW SE direction along the peak of the mounds and dipping vertically. The maximum length of the quartz vein is 80 M and width of the veins is 40 M. the Quartz is exposed along the strike direction. At some places the biotite rich schist is showing multiple joint planes, which are parallel to the strike of the country rock. The country rock have undergone weathering, therefore the scree of country rock with quartz weathered pieces are spreading in the area. The quality of the quartz found to be good with compact semicrystalline granular Structure. 3.4 RESERVES The geological reserves are given in Table - 3 below.

6 5.0 Water Requirement Effect of quarrying activities on the ground water regime are meager and deterioration of ground water quality is ruled out as quarrying operations are in a small scale and mining will be located at higher levels than the ground water table. Total water requirement for the quarry lease area is 6 KLD. This requirement will be met through bore wells. The water will be used for domestic purposes, dust suppression and green belt development. Domestic wastewater will be sent to the septic tank followed by soak pit. The break-up of daily water requirement for the proposed quarry lease area is presented table below.

Drinking water is supplying to the workers from the tankers.

7 5.4 Climatic Conditions The quarry lease area experiences semiarid climatic condition. The area experiences 1000mm average annual rain fall. Maximum temperature is 48 0 C & Minimum temperature is 25 0 C. The general wind direction is SW to NE & SE - NW. 6.0 ENVIRONMENTAL MANAGEMENT PLAN The activities at the QL area shall have both positive and negative impacts. In order to reduce the negative impacts owing to activities in the QL area under consideration, measures have been integrated in the process at the planning stage itself. Environmental management approach includes actions to protect environment by using various means at different stages of the project. The measures result in reduction of the impacts at the sources itself. Some of the measures result in the change in technology / process thereby reducing and or eliminating some of the adverse impacts. In a few inevitable cases the remedial solutions are provided to counter / minimize the negative impacts. 6.1 Air Pollution Control Measures The area is surrounded by agricultural lands and there are no industries nearby. Hence natural air is available in this area. There are chances for air pollution at the time of Jackhammer drilling and at the time transportation of Quartz. But this air pollution will be controlled to the ambient air quality standards (24 hours) i.e. SO 2 =80µg/m 3, NO 2 =80µg/m 3, Particulate matter (PM 10 ) = 100µg/m 3, PM 2.5 = 60 µg/m 3 by applying wet drilling with the jackhammer. Wet drilling Regular spraying of water by water tanker Length of Approach road 900m. Water for sprinkling 3.0 KLD Regular maintenance of vehicles and machinery Providing dust Masks to workers. Plantation along haul roads 6.2 Noise Pollution Control Measures In the quarry, the machinery operations like jackhammer drilling, compressor and excavators will generate noise pollution. The noise pollution control measures are given below : Workers will be provided with earmuffs, earplugs. Regular maintenance of vehicles and machinery Reducing unnecessary usage of horns Limiting the speed of vehicles entering and leaving the quarry to 25 kmph.

8 6.3 Greenbelt Development The proponent proposes for afforestation along the Eastern boundary of the quarry lease applied area within the 7.5 M buffer zone over an extent of 1000 m 2 in phased manner during the plan period with suitable plants. Year Area No. of Plants 5 th year ( ) Water Pollution Control Measures There are no chances for changes in quality of surface water or ground water the quarry operations will be carried out on slopes of the rocky terrain. No solid waste generation from the mine. Hence neither the ground water table nor the general surface drainage pattern is affected. No water will be discharged from the quarry. Following measures shall be taken: It shall be ensured that good quality potable water is provided for drinking purposes. Good sanitation facilities (toilets with septic tank followed by soak pits) shall be provided and maintained for good hygienic conditions. Garland drains with silt traps will be provided all along the dump. The spillages from fuelling of machinery shall be avoided and in case of any spillage the same shall be handled properly. Likewise the spent lubricating oils etc., shall be safely collected and properly disposed off. 6.5 Solid Waste Management The Quartz of this area is not meant of captive use. The mineral quartz will be sold to the Ferro Alloy Industries, Foundries, Ceramics and to Glass Industries. 6.6 Socio-economic Environment The main occupation of villagers is agriculture, working in quarries and sheep raring. The commencement of quarrying activity in this area improved the socioeconomic status of the local people by creation of employment and paying taxes to gram panchayat. 6.7 Occupational Safety & Health Management The lease area does not involve any hazardous methods. The quarrying is simple and open cast mining method. In this, the possibilities of small injuries are anticipated. The lessee is providing First Aid facilities at quarry site and temporary Office room.

9 The lessee will provide PPE (Personal Protective Equipments) to the workers based on their nature of work. The following PPE is proposed to be distributed. Helmets once in three years as needed under Mines Act Hand gloves will be provided to employees. Safety shoe to all the employees twice a year as per the same statute. Nose masks once two months (Actually these are the cotton thin towels) Other step to improve safety conditions is to inculcate the safety culture among the persons working. 6.8 Monitoring during Project Phase (active mining) Pollution monitoring program includes periodic analysis of air, noise levels and groundwater samples. Groundwater samples at representative locations within and nearby the lease area shall be periodically analyzed to detect contamination if any. In the event of any contamination, concerned authorities shall be notified immediately and appropriate corrective measures shall also be initiated. The monitoring shall also help in knowing the effectiveness of abatement measures and also be a guide for further steps to be taken, if required Monitoring Strategy The monitoring of various environmental parameters is necessary and is a part of 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 quality to check whether the quality of emissions/effluents is maintained within the permissible limits. Environmental attributes should be monitored as given below: Ambient Air quality Water quality Noise levels Soil characteristics Locations and frequency of monitoring should be as per the guidelines of APPCB 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

10 matter, Sulphur dioxide and Nitrogen oxides in the ambient air within the project boundaries will be monitored at regular intervals 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 sound pressure level meter is essential for this purpose. This work can be handled by plant authorities themselves or by hiring services of an external agency. Noise surveillance is for the benefit of the workers wellbeing and to keep track of machinery wear and tear Water Quality Monitoring Groundwater near the project site will be routinely tested for its quality. No contamination of groundwater is expected. Groundwater is recommended to be monitored in at least other wells/ bores in the area adjacent to the QL area in the direction of ground water flow to keep surveillance on the groundwater quality Machine and Equipment Safety To prevent and control hazards related to machine and equipment use, measures for the enhancement of visibility should be applied throughout the mine. Specific visibility management practices may include the following: Use of reflective markings on structures, traffic junctions, and other areas with a potential for accidents. Use of contrast Colouring on equipment / machinery, including the provision of reflective markings to enhance visibility. Use of moving equipment / machinery equipped with improved operator sight lines. Installing safety barriers in high-risk locations of internal roads / transport corridors. Barriers may be constructed with refuse or other materials capable to stopping vehicles 6.9 Budgets for Environmental Protection Measures The proponent will allocate budget of Rs Lakhs (Capital Cost) and 2.60 Lakhs (Recurring Cost per annum) for the environmental protection measures. The component wise budget break-up for environmental management plan is given in table below.

This point will be dealt only after the extracting of Quartz up to ground level. 7.0 Progressive Mine Closure Plan a. Mined out land Quartz mining will alter the physiographic scene, as a large pit of 6.91ha.with 6 m. depth will be formed at the end of the plan period. b. Water Quality Management Samples from the bore wells in the nearby village shall be tested for relevant parameters periodically and the results submitted to the regulatory authorities. The water quality is not expected to change owing to operations at the QL area. In case any change is observed, the cause of the resulting in the change shall be identified and necessary corrective measures shall be adopted. c. Air Quality Management Ambient air quality shall be monitored periodically. This shall indicate the levels of air pollution. Depending on the ambient air quality, necessary mitigation measures will be

12 adopted to maintain good ambient air quality. With the advent of technology newer methods shall be adopted to minimize the problems at the source itself. d. Solid Waste Management The Quartz of this area is not meant of captive use. The mineral quartz will be sold to the Ferro Alloy Industries, Foundries, Ceramics and to Glass Industries. e. Top Soil Management The lease area contains Quartz exposed on the surface. Topsoil available between the joints of the rock. Top soil will be stored separately and will be used for plantation along approach road. f. Infrastructure Office, rest rooms, first aid room, shelters, toilets, bore well for drinking water will be provided in the NE corner of the QL area. g. Disposal of Mining Machinery No mining machinery will be disposed h. Safety and Security All safety statutory measures will be adopted in the mine while working in the mine. i.

13 8.0 CONCLUSION The mining activities of the Quartz Mine in Ha., in Sy. No. 319(P) of Dubagunta Village, Pamuru Mandal, Prakasam District, Andhra Pradesh will be environmentally compatible to the surrounding with the proposed environmental control measures implemented during quarry operations. The study identified the environmental issues viz., dust generation and noise levels due to drilling and material transportation, on haulage roads etc. Management of ambient air quality at quarry lease area is important at all stages of the mine cycle. Fugitive dust emissions from stockpiles and other exposed areas should be minimized by using dust suppression techniques for roads and work areas, optimization of traffic patterns, and reduction of travel speeds. Thus it can be stated that the quarry operations will not have any adverse effect on the surrounding environment and habitation, if the proposed environmental management plan is adopted.
