4 1.4 Project Location and Accessibility: The lease area is located in Sy No.333 of Arikara Village, Alur Mandal, Kurnool district, on a elevated terrain situated 2.0 km NW of Arikara village and is 2.8 km SE of Alur village. Kuruvalli village situated at a distance of 4.4 Km. SW of the Quarry lease applied area. The lease area is falling in Topo sheet No. 57 E/3 with Latitude N and Longitude E Location map showing project site location is given in plate-i The quarry area is well connected with road network. The quarry site is connected to black topped roads. These roads provide good access to any place. A metal road connects the quarry site with the State Highway. Topographical map of the area in 10 km radius of the mine area- plate-ii 1.5 Geology and Exploration: a. Regional Geology: The oldest rocks in the area belong to migmatite complex, represented by migmatised quartzo-felspathic gneiss are exposed in the district. Regionally the area represents part of the Archean Granite Greenstone terrain of the Dharwar Craton. It has schistose rocks of greenstone belts. These are reffered to as Archean greenstone belts. This has been included by the rocks of Penninsular Gneissic Complex (PGC) which has gneisses, migmatite and migmatized granite suit of rocks. Gneisses and migmaties include porphroblastic hornblende gneiss, hornblende biotite gneiss, nebulitic to homophenus hornblende gneiss, pink and green coloured migmatitic gneiss closepet Granite and its equivalents, belong to the Proterozoic age have intruded the above set up. The greenstone belts, gneisses, migmatites and younger granitoids are intruded by the mafic dyke swarms. The stratigraphy of the region is given below.

5 Younger intrusive Archean Epidote Veins Quartz Veins and reefs Veins of alkali feldspar Dolerite/Basalt/Gabbro Dykes Biotite Granite Peninsular gneissic complex Hornblend granite Biotite granite gneiss Hornblend granite gneiss Porphyritic hornblend granite Dharwar Super Group Amphibolite, Hornblend schist b. Local Geology: The subject are belongs to slope of a hill raising to a height of about 24.0m with boulders from ground level. The QL area is passing through on centre of Northern slope of the hill. However the granite boulders and sheet rock is well exposed without any over burden. It represents late magmatic injection of closepet granite. Parameters for evaluation of Colour Granite: The term granite refers to rock comprising of essential minerals like quartz, orthoclase or microcline and plagioclase. Smaller amounts of biotite, muscovite or amphibole (hornblende) are present as accessory minerals. The colour combination, orientation of minerals and texture often present a very attractive pattern especially when the surface of granite is polished. The fabric orientation, homogeneity of color, texture, structure, as they appear in a sample, together with its mechanical properties like hardness, wear resistance, durability determine the value and marketability of a certain granite deposit.

6 1.6 Exploration/Prospecting: The dolerite dykes of Kurnool district are well known. This particular site has been selected after obtaining representative samples of the material from various locations and getting them cut and polished into hand samples and finally selecting the site which contains 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. The estimated resource of the colored granite in the lease hold area of extent 1.0 ha is of the order of about M 3. Categorization of Reserves: S.No Area details Area(m 2 )/Reserves(M 3 ) 1 Lease area Mineral bearing area M 2 3 Total geological reserves of color granite M 3 4 Proved reserves of color granite- G1 category M 3 5 Recoverable reserves of color granite of the total resources M Mining Methodology: The mining is carried out by opencast semi mechanized methods using compressor operated jackhammer drills, excavators and dumpers. The mining will be by linear cut method which involves separation of the primary block from mother rock. Initially, the primary sheet rock is made to expose by removing rubble and weathered rock. After detailed study of the sheet rock; the potential defect free granite areas will be demarcated. To separate the defect free granite blocks primary cutting will be taken up by line drilling method and working face is developed. Once the working face is developed, the primary cuts are made by keeping in view the fabric orientation and homogeneity of color, texture and structure, with a maximum of 10m length, 3m width and a height of 6m. Such primary block will be cut into secondary blocks once again by

7 jack hammer line drilling and feather & wedge cutting then the demarcated blocks will be dislodged from the sheet rock by an excavator. Line drilling method will be used for cutting and separation of the primary and secondary blocks by involving drilling and mild blasting or feather and wedges or chemical expansion agents. The drilled holes are charged with low/mild explosive cartridges and instantaneous detonators for smooth finishing. Thus the block is separated from the mother rock which will be pulled out from the face with cranes. Transportation of the commercial blocks is by heavy duty trucks either to polishing Industry or to nearby port for export as raw blocks. Schematic Diagram/Flow Chart: Parent rock Separation of primary color granite blocks from parent sheet rock by line drilling involving controlled blasting by using mild explosives or chemical expansion agent Separation of secondary blocks from the primary block by line drilling coupled with wedge splitting or chemical expansion agents or feather & wedges The secondary blocks are pulled out from the parent rock by cranes/poclain. The retrieved blocks are finally finished by chipping, cutting and chiseling The blocks are sent to end users by heavy duty trucks to buyers either polishing Industry or nearby port for export. Extent of mechanization: The machinery used for Granite mining is:

8 S.No Item Nos. 1 Excavator (1.0 m 3 bucket capacity) 1 2 Jack hammer with 32mm drill rods CFM-AIR Compressor 1 4 Trucks/tippers(17MT capacity) Utilities: a. Power: The power connections are drawn from nearby power lines. About 200L of Diesel/ day is required for the operation of the machinery Water: At mine site, water is used for: Wet drilling Water sprinkling on quarry roads and approach roads for dust suppression. The mine requires about 2.4 KLD of water for operations including drilling, dust suppression and domestic purposes. For drinking purpose of the persons working in the mine and for sprinkling purposes, water supply is drawn from the nearby bore wells adjacent quarry & agricultural fields on contract basis by tankers Mining program for the next 3years: The proposed production of the colour granite for the next three years is at the rate of about 1510 M 3 /annum. The waste material generated from the production is at the rate of 7370 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 b) Blaster Cum Mate c) Excavator operators d) Compressor operator

9 e) Tipper operators f) Drillers g) Helpers h) Cutters i) Watchman BASELINE ENVIRONMENT: The environmental quality in the surrounding area of mine serves as the baseline status and also for identification of environmental impacts/concerns corresponding to project area. 2.1 Climate Scenario: The area falls in arid region and experiences maximum temperature of 41 C in summer during April & May, while minimum temperature of 17 C in winter during December & January. The average rain fall is of the order of 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: At mine site, water is used for: Wet drilling Water sprinkling on quarry roads and approach roads for dust suppression. The mine requires about 2.4 KLD of water. This includes water for drilling, dust suppression and domestic purposes. For drinking purpose of the persons working in the mine and for sprinkling purposes, water supply is drawn from the nearby bore wells adjacent quarry & agricultural fields on contract basis by tankers.

10 2.3 Land Environment: a. Seismicity: The mining lease area represents a part of stable Dharwar Craton of the peninsular shield area and as a result it comes under stable Seismic zone. b. Soil: The surrounding areas of the mine site are occupied by brownish red sandy soils whereas the quarry site is covered with sheet and boulders and is devoid of soil cover. c. Land use pattern: The mine area is covered with sheet and boulders of granite. It is rocky in nature and is barren. All around the lease area the country is with undulatory topography covered with brown, brownish red sandy soils. The quarry land belongs to the Govt. of Andhra Pradesh. d. Land degradation: The mining operations to win color granite from the lease area results in land degradation of the preexisting rocky barren area. After complete excavation of the granite, the preexisting topographic levels of the mine area will change, resulting in some pits. Such degraded area will be reclaimed by filling and leveling and can be used for greenery development. e. Solid waste storage: The granite mining is on the hump structure, which does not have soil cover, hence there will not be any scope of soil generation. But the 80% of waste that is generated after the recovery factor of the commercial blocks of color granite production, during the life of the mine, amounts to M 3 The dumping of the waste will be on the area earmarked in the Southern side of the lease. This waste will be used for refilling of the pits resulted for greenery development and also for leveling the low lying areas & laying of new roads in and around the lease area.

11 2.4 Flora & Fauna: The common floral species found in the area are neem,banyan, tamarind, mango, bamboo, eucalyptus etc. However the mine area represents a rocky terrain and does not consist any species of major vegetation but for the presence of thorny bushes and straw grass along the intervening clay portions among boulders. No wild animals are seen in the area. 2.5 Human settlement: The population of the nearby villages is given below S.No Village Population 1 Arikara Alur Kuruvalli Hattibelagallu 930 (Source: Censes 2011) 2.6 Socio-Economic study: The people living in neighboring villages are mainly depending on agriculture. 5-10% of the villagers thrive on 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 Adoni, Bellary, Guntakal and Pattikonda, by wellmaintained black topped wide roads. The cities/ towns which are nearby are well equipped with good educational, hospital and communication facilities. 2.7 Air environment: The major sources for air pollution are jackhammer drilling, blasting, loading and vehicular movements. The dust generation will be controlled by water sprinkling, minimizing air borne dust. The fumes produced by diesel engines will be kept within permissible limits by regular maintenance as recommended by the manufacturers.

12 2.8 Noise environment: In the quarry operations, noise pollution will be due to jackhammer drilling, blasting and vehicular movements. The noise pollution because of blasting which will be done occasionally will however be momentary. Regular maintenance of the machineries and vehicles will also reduce noise pollution considerably. The adverse effects of noise to the mine workers are prevented by providing ear masks. Likewise, the noise pollution in the area will be absorbed to an extent by the trees which are proposed to be grown in the inactive zones of the lease area and on the sides of the approach roads. 3. ENVIRONMENTAL MANAGEMENT PLAN The mineral deposits are exploited from the earth s crust for the sustainable growth and development of the mankind. This mining activity is likely to cause some adverse impacts on the environment and the ecosystem of the area. Therefore, it is obligatory for the lessee to implement suitable control measures to mitigate the adverse impact of the mining operations. It is possible to control deterioration of environment due to mining activity by adopting and monitoring a few practices as described here under. 3.1 Air pollution control: The meteorology of the area becomes an important parameter in environmental management, especially in the mining areas and settlements. Suitable measures to protect the inhabitants/workers and environment from the dust emissions from the mining activity and smoke emissions from the vehicular movements are given below: Apart from the dust suppression methods described above, dust masks will be provided to the workers as additional protective measure. Frequent water sprinklings on the haul roads, muck pile, dump area etc. Drill rods will be covered with wet gunny cloth Regular maintenance of machinery and vehicles.

13 3.2 Water pollution control: The quarry operations do not affect the water regime in the area, because they are located much above the ground water levels and also far away from the water bodies. The dust generated from the granite mining is least soluble in water, the water pollution due to mining activity either from the mine pit or from the dump is minimal. Flow of sediments from the dumps during rainy season will be controlled by garland drainage if necessary. Mitigation measures: Care will be taken to avoid fuel spillage and all the waste oils from the vehicles and machinery will be sold off to an authorized dealer for recycling. Retention wall at the foot of the dump area if necessary. Growing vegetation on slopes of the dumps. 3.3 Noise pollution control: Proper and regular maintenance of machinery and vehicles. Workers will be provided with ear muffs, ear plugs and gloves. Speed limit of the vehicles in the mine area will be maintained at 15kmph. 3.4 Green belt development: The proponent has plans to develop greenery on the approach/ haul roads, in the non-potential area around the mine pit, in the area beyond the lease boundaries at the rate of 30 to 50 plants per year with the permission of local authorities. The broken 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 on rocky hump structure. As such there is no appreciable amount of soil in the lease area. The land degradation resulting from the mining activity will be mitigated by reclamation and greenery development.

14 Solid waste management: Due to the inherent problems in producing colour granite blocks, about M 3 of waste will be generated in the next 5 years and will be stacked on the Southern side of the lease area. This waste will be used for refilling of the pits. Soil will be spread over the area and plantation will be taken up. 3.6 Measures to improve Socio-economic conditions: The mining project is with low capital layout and provides employment to 27 persons directly and equal number indirectly. Due to mining the State Govt. will get substantial income in the form of Royalty and sales tax. Such income will be made use for the 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., exists 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 27 persons including technical and nontechnical cadres for carrying out mining operations. The lessee proposes to employ the local people. In addition, there will be business opportunities to serve the mine workers and mine operations. This together will enhance economic status of the local village people. It also generates income to the State Government, local bodies and local inhabitants. 3.7 Occupational safety and Health management: The proponent will educate the mine workers about all the safety measures to be taken up during mining activity. The safety measures in the following categories are adhered very strictly during mining operations.

15 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 Providing protective equipment (PPE) like safety helmets and foot wear to workers. In addition ear, eye, and hand protection devises (ear muffs, goggles, hand gloves) will be provided. Training of employees on the recognition and prevention of occupational hazards specifically applicable to quarry workers. Periodical medical examinations of all workers, so that any adverse effects of mining may be detected in its early stage. Medical records of each individual will be maintained. Use of explosives: Blasting activities will be conducted strictly as per the provisions of MMR The mine workers will be educated on safety measures. 3.8 Post Project monitoring: Post 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 will be notified immediately and appropriate corrective measures in consultation with an approved consultant shall be initiated.

16 3.9 Monitoring strategy: Monitoring of various environmental parameters is part and parcel of the environmental protection measures. A well-defined monitoring program would be employed with qualified and trained personnel to monitor the ambient air quality, noise levels and water quality to check whether the quality is maintained within the permissible limits or to suggest the measures to be taken to maintain the congenial environment A comprehensive monitoring program is drawn for the following environmental attributes Air pollution and meteorological aspects. Water quality Noise levels Soil characteristics Ecological preservation etc. Locations and frequency of monitoring will be as per the guide lines of AP Pollution Control Board and MoEF & SEIAA Ambient Air Monitoring: As per MoEF, there is a need to identify a minimum of 3 ambient air monitoring stations at 120 angle keeping the main source in the centre. The ground level concentrations of suspended particles, sulphur dioxide, nitrogen oxides, carbon monoxide etc. in the ambient air in the outside mine area and in the surrounding villages will be monitored at regular intervals. Any deviation from the standard, predicted/expected values will be monitored and necessary measures to correct them will be taken up Noise level monitoring: To assess the efficiency of the maintenance schedule undertaken, monitoring of noise level is essential to minimize to permissible limits and to take protective measures. For this purpose an instrument like `Dosi meter

17 will be used by the mine authorities themselves or hiring the services of experts. Noise monitoring will be conducted periodically. If any deviation than the permissible levels as per MoEF & SEIAA are observed then the necessary corrective/ control measures will be taken Monitoring of water quality: No, contamination of ground water and surface water is expected as the mining is on hump structure and no effluents will be generated/ released either during granite mining or from the dumps. Garland drains will be made around the dumps to avoid sedimentation from the dumps due to rain water. However the ground & surface water samples will be collected periodically and tested for any change in water quality. At least at two locations in the direction of natural flow will be monitored to keep surveillance on water quality Budget for Environmental Protection Measures: Sri. T.K.Kalimulla will allocate INR 4 Lakh for Capital cost towards EMP and Rs.1.5 Lakhs per Annum towards recurring expenses as per details given below;

19 3.11 Reclamation & Rehabilitation: The proposal for the reclamation of the degraded land due to mining will be taken up after complete excavation of granite up to the optimum depth / economic viability. As there are no habitations within the lease area, the Rehabilitation question does not arise Progressive mine Closure plan: Mined out land: At the end of the mining, the mined out land will be refilled with the waste material stacked in the Southern part of the lease area and greenery will be developed over it. Afforestation: Every year about saplings are proposed to be planted in the approach road to the lease hold and along the borders of the other approach roads with the permission of the local authorities. Infrastructure: Since the mining is on hump structure of barren nature, only existing infrastructure available in the nearby villages will be utilized, hence no new infrastructure developments are proposed. After completion of mining after complete excavation of granite, the temporary structures at the mine site will be dismantled. Disposal of Mining Machinery: As all the mining machinery is movable and is proposed to be hired, the question of the 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.

20 Disaster Management and Risk management: The mining lease area represents a part of stable Dharwar Craton of the peninsular shield area and as a result it comes under stable Seismic zone. Therefore, the disaster and Risk due to situations like subsidence, seismic activity etc. are not anticipated in the mine. Care and Maintenance during Temporary closure of the mine: Due to any eventuality, if the mine is temporarily suspended, the Lessee will appoint watch and ward throughout and will ensure the safety and security of the mine. The technical personnel will be paid salaries. The workers drawn from the nearby villages will be paid wages even while they will be engaged in their agricultural activities. 4. CONCLUSIONS: The Colour Granite mining over an extent of 1.0 ha. in Sy No. 333 in Arikara Village, Alur Mandal, Kurnool district, AP in favor of Sri.T.K.Kalimula, 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. A turnover of about 75,00,000 Lakhs per Annum is expected from this quarry operation. It may be noted that about 30% of this amount will comprise of wage constituent. Hence in this rural area it is a source for employment generation. Producing valuable granite blocks of high value is most welcome. The proponent assures to excavate the granite by taking all precautions required to protect the environment from possible adverse impacts. To conclude, it has to be stated this colour granite quarry of 1.0 ha in Arikara village is not likely to adversely affect the environment as all necessary steps to mitigate will be taken according to this EMP.
