4 1.4 Project Location and Accessibility: The lease area is located in Sy. No. 10 & 23 of Sankavaram Village, Kanigiri Mandal, Prakasam district is on the NE side of Chintalapalem at a distance of 1.5 km. The site can be located in Topo Sheet No. 57 M/11, N : E. Location map showing project site location is given in plate-i The quarry area is well connected with road network. The Kanigiri- Kandukur highway is at a distance of 4.0Km. on the south side. The quarry area is well connected by black topped roads to Ongole, Chirala, Guntur, etc., Chennai Vijayawada-Visakhapatnam-Howrah rail line runs at a distance of 55.0 Kms. A metal road connects the quarry site. Topographical map of the area in 10 km radius of the mine area- plate-ii 1.5 Geology and Exploration: Regional Geology: The Kanigiri Granite trends NE-SW it is an intrusive into the Dharwar schist of Nellore Khammam schist Belt intruded by Granites and Gabbro dips vertically. The dolerite dyke is intruded into the preexisting country rock of Archean age. The width of the dyke is about to a length The quartzchlorite. Aplites in the form of veins, stringers and irregular veins cut across the granite. The general stratigraphy of area. Stratigraphic Units ERA Group Lithology Recent Paleo Proterozoic Peninsular gneiss Top red soil Dolerite, Gabbro Migmatites, Hornblende-Biotite gneiss Archean Dharwar Banded Ferrugenous quartzites, Biotite-Chlorite schist, Amphibolite Hornblende-Biotite schist.

5 a) Local Geology: The applied area without elevation to normal ground level and in adjoining quarries also likewise. In the exposed pit black granite strike direction NE- SW, dips vertical to sub vertical. In the lease area black granite is DOLERITE where it commercially named Black Granite as an Intrusive rock. The Dolerite intrusive rock megascopic ally is a massive nature, hard and compact hardness of about Mohs scale, colour steel grey to jet black and it shows equigranular texture consisting of fine grained pyroxeneshypersthene and plagioclase, water absorption is very less due to even fracture. The exposed top layers seems to be varying size of small to large boulders which shows spheroidal weathering due to this effect more rejection upto 4.0 Meters (shallow depth) and hence rate of recovery 5-10% below the bouldary layer. The deposit exhibits closely spaced joints on the surface when it goes depth is gradually increases. It indicates medium to large sizeable blocks can be recovered from near depth of working pits. If dyke with more than 25 M thick will be more of sheet in nature and economically viable to find application of gang-saw cuttings top produce mega rough blocks the same here also scope to encounter after going to a further depth of 2 to 3 M. Structurally, no folds or faults in the quarry lease area. Intrusion of small pegmatite veins between the country and best rocks vein noticed in SW side less the 5-10 cms. The soil and small boulders exposed at the surface level were weathered to a thickness of 2-3 M. which is treated as overburden and most o the overburden was removed from this area and sheet rock was exposed in working pits. Parameters for evaluation of Black Granite: The quality of the dyke material determines its commercial value the parameters to be considered are pleasing colour of the background minerals, grain size, texture, freedom from inherent defects like joints, fractures, hairline cracks and other defects and the inherent quality to get good glossy

6 polish and amenability to production of large blocks with minimum use of explosives and wastage. 1.6 Exploration/Prospecting: The dolerite dykes of Prakasam district are well known. This particular site has been selected after obtaining representative samples of dyke material from various locations and getting them cut and polished into hand samples and finally selecting the site which has given the most attractive hand samples. 1.7 Reserves: Corroborating the detailed geological studies and the pit data, the reserve estimation was carried by the cross sectional area method. For proved reserves, on the basis of lithological homogeneity observed in the existing pit with a depth of 3m was taken into consideration and same is being extrapolated up to a depth of 20m. (which includes present pit depth of 10m.). The total geological resource of black granite in the lease area is of the order of about 5,85,980 M 3 up to depth of 20m. Categorization of Reserves is indicated below: S.No Area details Area(m 2 )/Reserves(M 3 ) 1 Lease area Hts 2 Mineral bearing area m 2 3 Total geological reserves of 5,85,980 M 3 black granite up to 3 m. depth 4 Recoverable reserves of black granite of the total resources 16,498 M Mining Methodology a) Method of Mining: Open cast method of semi-mechanized mining will be adopted to extract the dimensional blocks of required size from the area. Development and earth work will be carried out by hydraulic excavator and tipper combination. Rest of work like drilling, blasting and dressing will be done manually with aid of portable compressors and Jack Hammers.

7 Drilling: The drill holes of 32 mm dia. are drilled to an average depth of 3.0 M. with closely spaced line drilling for producing dimensional blocks. The maximum number of holes at one phase of blasting will be Mechanisation: Hydraulic Excavator will be used to develop the mine faces and move the blocks for manual cutting and dressing. Two tippers shall be engaged for removal of waste. Schematic Diagram/Flow Chart: Parent rock Producing of large blocks by line drilling and controlled blasting. Reducing the bigger size blocks to gang saw size by drilling closer holes and splitting by using feather and wedges. Smooth finishing of the blocks by chipping, cutting, chiseling. Dispatching the finished product to local C&P units or for export. Producing smaller size blocks for local consumption by similar method. S.No Item Nos. 1 Jack hammer 6 2 Compressor 2 3 Trucks/tippers 2 4 Poclain Utilities: a. Power: The power connections are available at Chintalapalem and the proponent gets the power from there. About 300L of Diesel/ day is required for the operation of the machinery

8 Water: At mine site, water is used for: S.No Purpose Quantity Remarks on Waste Water a) Water for Sprinkling on haul roads 1.6 KLD All water will be absorbed by the ground b) Water for Drilling 0.2 KLD Water will be evaporate. c) Greenbelt 0.4 KLD Water will absorbed by the soil. d) Domestic 0.2 KLD Water for drinking Total 2.4 KLD The mine requires about 2.4 KLD of water. This includes water for drilling, dust suppression and domestic purposes. Potable water for drinking is available in the villages nearby and this is procured by tankers. Water for sprinkling purposes is drawn from the nearby bore wells by tankers Mining program for the next 3years: The proposed production of finished black granite for the next three years is at the rate of about 2000 M 3 /annum Man Power Requirement for Mining Operations: Since it is a B2 Category mine, the following personnel shall be employed Technical, skilled and semi skilled personnel a. Mines manager (Permit Manager) - 1 b. Excavator Operator - 2 c. Compressor operator - 1 d. Drillers - 2 e. Helpers - 9 f. Afforestation - 1 g. Watchman - 2

9 2.0 Baseline Environment: The environmental quality in the surrounding area of mine before commencement of operation serves as the baseline status and also for identification of environmental impacts/concerns corresponding to the project. 2.1 Climate Scenario: The area falls in Prakasam District which forms coastal region and experiences maximum temperature of 46 C in summer during April & May, while minimum temperature of 20.0 C in winter during December & January. The average rain fall is of the order of 820 mm/year. The area experiences maximum rain fall due to SW monsoon during June September. It also receives rain fall due to NE monsoon during November and December. 2.2 Water environment: The ground water and water in the surrounding areas are not likely to be effected due to the quarrying operations, since no pollutants or effluents will be released from the quarrying operations. 2.3 Land Environment: a. Seismicity: The mining lease area falls in the low specific velocity zone of the peninsular India and as a result it comes under a low Seismic zone. b. Soil: The surface cover consists of soil, pebbles and rough stones and the same has been stacked separately and will be used for plantation in the inactive areas. c. Land use pattern: Cultivation is done in the adjoining areas away from the quarry. d. Land degradation: The mining operations to win black granite from the lease area necessarily result in forming a pit in the pre existing rocky area. After complete excavation of the quarry, the pre existing surface levels of the

10 mine area go below the ground level. Such area will be reclaimed by filling and leveling and can be used for greenery development. e. Solid waste storage: The dolerite mining is in flat country, which consists of soil, pebbles and rough stones which will be stacked on the West side of lease area separately. The waste generated is also stacked separately and will be ultimately used for back filling. 2.4 Flora & Fauna: The site area is a flat country, no wild animals are found. Only thorny bushes are found in the area. 2.5 Human settlement: Population Projection: The population of the villages falling within 5 Km radius as indicated below: 2.6 Socio-Economic study: S.No Village Population 1 Sankhavaram Chintalapalem Chinnairlapadu Kodigudla padu 961 (source:censes 2011) Socioeconomic environment of mine area includes demography, basic amenities like housing, health care services, transportation, education and cultural activities etc. The people living in neighboring villages are mainly depending on agriculture.5-10% of the village people thrive on occupational professions such as carpentry, goldsmithy, blacksmithy, pottery etc. The persons working in the mine stay and commute from the nearby villages. The surrounding villages are well developed and are well connected to the major Cities/ towns like Ongole, Chirala, Guntur etc., by well-maintained black topped wide roads & trains. The cities/ towns which are nearby are well equipped with good educational, hospital and communication facilities.

11 2.7 Air environment: Machines like tractor mounted compressors, poclains and tippers will be in operation. The fumes/smoke generated will be within permissible limits. Blasting will be occasional and the blasting fumes will dissipate in a short time. The dust generated due to drilling will be suppressed by sprinkling water. Dust produced due to blasting will settle down in a short time. Since human habitations are far away, the impact of quarrying will be negligible. 2.8 Noise environment: In the quarry operations, noise will be due to jackhammer drilling, blasting, stone breaking and vehicular movements. The noise because of blasting will be contained by adopting systematic blasting methods especially in view of the fact that blasting is carried out in conjunction with chemical agents and feather & wedges, minimum quantity of explosive will be used. 3.0 ENVIRONMENTAL MANAGEMENT PLAN The mineral deposits are exploited from the earth s crust for the sustainable growth and development of the civil society. This mining activity does not cause adverse impact on the environment and the ecosystem of the area. However, small amounts of dust generated during the process of mining will be controlled by water sprinkling. The workers will be provided with masks, ear muffs and helmets to protect them from possible air and noise pollution. 3.1 Air pollution control: To protect the inhabitants/workers and environment from the dust emissions from the mining activity and smoke emissions from the vehicular movements will be regulated as below: Dust masks will be provided to the workers, Frequent water sprinkling on the haul roads, muck pile, dump area etc., Drill rods will be covered with wet gunny cloth regular maintenance of machinery and vehicles.

12 3.2 Water pollution control: The quarry operations do not affect the water regime in the area, because they are located close to ground level and much above the ground water levels and also far away from the water bodies. Mitigation measures: Care will be taken to avoid fuel spillage and all the used oils from the vehicles and machinery will be sent for recycling. 3.3 Noise pollution control: Proper and regular maintenance of machinery and vehicles will ensure least production on noise while working. Workers will be provided with ear muffs, ear plugs and gloves. Speed limit of the vehicles in the mine area will be maintained at 25kmph. 3.4 Green belt development: The green belt development is an effective way to check pollution and their dispersions into the surrounding areas. The proponent has plans to develop greenery on the approach/ haul roads, in the non-potential area, around the mine pit at the rate of 30 to 50 plants per year in the area beyond the lease boundaries with the permission of local authorities. The lease area will be planted with trees after complete extraction of the material and over the mine pit after reclamation. 3.5 Impact on Land & soil Environment and its Mitigation Measures: The mining area is located in a flat area. The land degradation resulting from the mining activity will be mitigated by reclamation by filling and greenery development. Solid waste management: The dolerite mining is in the flat area. The waste produced will be stacked at the non-potential area in the western side of the lease hold and will be used for approach road lying and leveling purposes.

13 3.6 Measures to improve Socio-economic conditions: The mining project is with low capital layout and provides employment to 17 persons directly and equal number indirectly. Due to mining the State Govt., will get substantial income in the form of seigniorage and sales tax. Such income will be used for the community developmental activities such as road laying, house construction for poor and for the improvement of educational, medical and communication facilities in the area. The mine area does not cover any habitation hence the mining activity does not involve any displacement of human settlements. No public buildings, places of worship, monuments etc., exist nearby. The mining operations will not disturb/relocate any village, hence there is no need for resettlement. Thus no adverse impacts are anticipated due to mining. Project Benefits: The project provides employment to 17 non-technical cadres for carrying out mining operations. The lessee proposes to employ the local people. 3.7 Occupational safety and Health management: The proponent will get the mine workers trained as per V.T. rules about all the safety measures to be taken up during mining activity. The safety measures in the following categories are adhered to very strictly during mining operations. General work place health and safety. Use of explosives. Physical hazards Fitness for work Travel and remote site health Noise and vibration General work place health and safety: The following safety measures will be taken at work place. By providing protective equipment (PPE) like safety helmets and foot wear to workers. In addition ear, eye, and hand protection devises (ear muffs,

14 goggles, gloves) will be provided. Employees will be trained about recognition and prevention of occupational hazards specifically applicable to quarry work. Periodical medical examinations of all workers, so that adverse effects of mining may be detected in its early stage. Medical records of each individual will be maintained. Use of explosives: Blasting operations will be carried as per MMR, 1961 and all necessary safety precautions will be taken under able supervision. 3.8 Post Project monitoring: Project monitoring includes the periodic analysis of air, dust, ground water samples. Ground water and soil samples at representative locations within and nearby the mine site shall be periodically collected and analyzed to detect the contaminations, if any. In the event of any contamination noticed, concerned authorities shall be notified immediately and appropriate corrective measures will be taken. 3.9 Monitoring strategy: After the environmental clearances are granted, an accredited agency will be commissioned for monitoring of various environmental parameters like ambient air quality, noise levels and water quality. Frequency of monitoring will be as per the guide lines of AP Pollution Control Board and MoEF & SEIAA Ambient Air Monitoring: Ambient air in and outside mine area and in the surrounding villages of quarry will be monitored at regular intervals. Any deviation from the standard, predicted/expected values will be monitored and necessary measures to correct will be taken up Noise level monitoring: The accredited agency or mine staff will monitor noise level with the help of a Dosi meter and if any deviation from the permissible levels as per MoEF & SEIAA guidelines are observed, necessary corrective/control measures will be taken.

15 3.9.3 Monitoring of water quality: No, contamination of ground water and surface water is expected as the mining is going on below ground level and no effluents will be generated/released. However the ground & surface water samples will be collected periodically and tested for any change in water quality Budget for Environmental Protection Measures: INR 4.0 Lakh for Capital cost towards EMP and Rs.2.0 Lakhs towards recurring expenses per annum.

17 3.11 Reclamation & Rehabilitation: The proposal for the reclamation of the degraded land due to mining will be taken up only after complete excavation. For this the Lessee will take necessary steps as directed by PCB/IBM. As there are no habitations within the lease area, the Rehabilitation question does not arise Progressive mine Closure plan: Mined out land: The waste material produced during mining will be stacked in a part of the lease area. At the end of the mining activity, the mined out land will be refilled and greenery will be developed. Afforestation: Greenery will be developed around the lease periphery and the mined out portion at the termination of operations Infrastructure: Only existing infrastructure in the area will be utilized. Disposal of Mining Machinery: Mining Machinery like the Compressors, tractor trailers, poclains etc. utilized in the mine are taken on hire and as such the question of their disposal does not arise. Safety and Security: All the statutory precautions will be implemented by the lessee for the safety and security of the personnel working in the mine. Disaster Management and Risk management: The mining lease area represents a part of low seismic velocity zone of Prakasam District. The risk of disasters is therefore minimal.

18 Care and Maintenance during Temporary closure of the mine: For any eventuality, if the mine is temporarily closed, the Lessee will appoint watch and ward throughout and will ensure the safety and security of the mine. 4.0 CONCLUSION: The Black Granite mining over an extent of ha. in Sy No. 10 & 23 in Sankavaram Village, Kanigiri Mandal, Prakasam district, AP in favor of M/s. Srinivasa Granites, will be environment friendly. However, with the proposed environmental control measures implemented during the mining operations, the possible minor impact on the environment will be minimized. The total turnover of the project would be in the order of Rs. 1,80,00,000/- per annum, out of this, the component on labour wages would be about 18,00,000 per annum. Hence in this rural area it is a source for employment generation. Producing valuable granite blocks of high value and earning valuable foreign exchange is most welcome. As minerals are site specific, we need to excavate by taking all precautions required to protect the environment from possible adverse impacts. To conclude, it has to be stated this black granite quarry is not likely to adversely affect the environment as all necessary steps to mitigate will be taken according to this EMP.
