DETAILS OF THE MINE Mine Area This mine lease (ML) area is located in government land and the Quarry Lease for Gravel & Building Stone over an extent of 1.235Hectares/ 3.05 Acres in Sy. No. 860, of Vedurupavuluru Village, Gannavaram Mandal, Krishna Dt, Andhra Pradesh. The quarry lease applied area is located southern part of Small hillock, over the gravel & building stone outcrop with a maximum elevation of 75M above ground level. The lowest & highest contours is 30M and 105M. Regional Geology The subject area is physiographical small hillock area. The area is constituted of naturally occurring gravel. The area constitutes southernmost part of Eastern Ghat Mobile Belt (EGMB), where the belt is tapering to less than 20 km width. EGMB is trending in NNE SSW in the area. They consist of Gollanapally sandstone, fluvial geological formation, quartz, k-feldspar, and garnet, and silliminite, graphite, with or without corundum. In the Northeastern part, a number of calc granulite and quartzite bands are present, within khondalite. Rocks of Upper Gondwana Group of the Gondwana Super group, comprising Tirupati Sandstone, Gollapalle/Chintalapudi Sandstone and Kamthi Sandstone are exposed north, northwest and east of Nuzivid. These rocks trend NE-SW with 200 dip towards SE Unconformably overlaying the Gondwana rocks is a small patch of Rajahmundry Sandstone, occurring NE of Nuzividu. The sandstone is brick red in colour and contains nodules of clay. Major part of the district in the southern part is represented by the alluvial plains forming the Krishna delta. The river Krishna and its tributaries have contributed to the formation of this alluvial plain. There is no significant surface drainage in these alluvial plains. The delta is relatively a flat area. The alluvial plains along the major course of rivers form the flood plain deposits. The coastal and deltaic alluvial plain extends from Challapalli on the west to Kolleti Kota on the east and up to the coast line on the south. The main geomorphic units exist in these plains are palaeo-channels, beach ridges, lagoons, sand spits and sand barriers. The predominant soils in the district are black cotton soils/deltaic soils, red loamy soils and sandy soils. Red clayey soils with sandy loam to clayey loam in texture and occur in the northern part of the district. The deltaic alluvium is grey brown to black in colour with fine to medium texture and poorly permeable. They are fertile soils. The coastal sandy soils occur all along the coast, highly porous and lack of binding material. The rocks of Archean age are overlain by Proterozoic cover sequence of Cuddapah super group and Kurnool group. The contacts between older crystalline and the younger sediment is marked by pronounced unconformity known as Eparchaean Unconformity. 8
Local Geology: The Quarry lease applied area is fallen southern flack of hillock with 75m above ground level, which was trending to NE-SW directions with the lowest contour 30m and highest contour 105 m. The gravel exposed on the surface of the hillock. Which was formed insitu weathering of Khondalite group of rocks of the Eastern ghat super group of rock of Archean age. Especially in this area the rock of Khondalite were semi consolidate nature i.e., Schist formation. The Khondalite schist is not formed fully rock due to low grade of metamorphism of sedimentary rocks. Hence it is considered (or) treated as Gravel of the weathered zone of Khondalite and semi consolidated rock material upto 6m from the top surface of the hillock (or) weathered zone of Khondalite. If any hard rock of Khondalite will be arrived i.e Gneiss form of Khondalite it will be stocked at dumpy yard. The gravel utilized for formation of kaccha road & filling of low laying area formation layouts. Reserves and Average Production The deposit is found to be small hillock land. Hence, cross sectional method adopted for Estimation of Geological Reserves. Accordingly, 3 Sections A-A1 to C-C1 has drawn at equal distance perpendicular to the trend direction of the deposit to estimate the reserves (Plate IV). In this method, the ore body is divided into blocks by constructing geologic sections at intervals along the transverse lines. The interval between sections may be constant or may vary to suit the geological setting and mining methodology. As the applied area is uneven shape we use the formula V= ((s1+s2)/2)*l1+ ((s2+s3)/2)*l2+ ((s3+s4)/2)*l3+ _+ ((sn1+sn)/2)*ln Where V= Volume L1, L2, L3, _, LN are perpendicular distances between the adjoining sections with areas S1, S2, S3, _, SN. 9

Environmental Management Plan The Environmental Management Plan envisage for this Mining Project is described here under with a strong commitment to follow the best Environmental Practices to reduce the negative implication to make this Project a sustainable development endeavor. The management action plan aims at controlling pollution at the source level to the possible extent with the available and affordable technology followed by treatment measures before they are discharge. Provided hutments in the southpart of the lease area for mine workers accommodation purpose. Air Environment and control measures: Dust emissions and particulate emissions mitigation measures will be through water spraying at all the sources of dust formation and these measures are further elaborated as follows: Regular water sprinkling at dust emanating sources viz., transportation through haulage roads, etc will be carried out. Regular grading of haul roads and service roads will be taken up to clear accumulation of loose material. Periodic maintenance of transport vehicles and equipment will be carried out to check emission levels. Greenbelt will be developed with avenue plantation all along the haulage roads and peripheral plantation all around the mine in order to control dust. Overloading of trucks will be avoided and carrying the mineral in covered trucks will be taken-up to minimize pollution levels. Water Pollution Management: No rivers and other perennial water courses flow through the ML area. However, during rains the water flows through the slopes of the ML area and across the mine lease boundary and joins a natural drainage. The rainwater that collects in the mine pit bottom during the rainy season will be utilized for water spraying on the haul roads and mining area. This water will also be used for the plantation in and around the Mine Lease area. The total water requirement will be 8.0 KLD which will be utilized from nearby water tankers and treated water from septic tank. The usage will be as follows: 13
The following that flows in the core zone will be routed adequately through channels to avoid any erosion and contamination. The mine pit water collected due to rains will be utilized for water spraying on the haul roads and for watering plantation. The waste water generated from the domestic usage will be fed to septic tank followed by soak pit. Noise Environment: The observed noise level for various activities is as under, where the noise levels cross the limits specified, the relevant PPE is being provide to the workmen. The machinery will be maintained properly to reduce the noise levels. The protective noise reducing gear like earmuffs, the company will provide earplugs. Proper maintenance of equipment. Machinery will be fitted with properly designed noise generating acoustic silencers. Providing noise insulation/padding wherever practicable. Proper maintenance and periodic lubrication of noise generating parts of the machines Provision of thick plantation in and around the mine is planned in order to reduce the noise and prevent it from reaching to surrounding habitation areas. Solid Waste Generation of Sub-Grade or reject material and waste it nill.100% of material will be utilized including dust or soil. GREEN BELT DEVELOPMENT The development of greenbelt in the peripheral buffer zone of the mine lease area will be undertaken well before the starting of the mining activity. Green Belt has been recommended as one of the major component of Environmental Management Plan, which will improve ecology, environment and quality of the surrounding area. Plantation will be done along the haulage roads and the unused area in the ML area will be developed with green cover. Suitable advice on this plantation activity will be consulted. 14
Concepts of Green Belt Development The concepts of Green Belt Plantation scheme are 1. Nature of Pollutants 2. Emission Levels 3. Maximum Impact zone CRITERIA FOR SELECTION OF SPECIES Species to be selected should fulfill the following specific requirements of the area - Availability of seed material - Tolerance to specific conditions or alternatively wide adapts ability to ecophysiological conditions. - Rapid growth - Capacity to endure water stress and climatic extremes after initial establishment - Differences in height, growth habits - Pleasing appearance - Providing shade - Ability of fixing atmospheric Nitrogen - Improving waste lands. DESIGN OF GREEN DEVELOPMENT The greenbelt shall be developed around the plant to act as a sink for pollutants, attenuation of noise levels and improvement in aesthetic quality of the plant. The following criteria shall be adopted in the design of greenbelt: 1. Generally fast growing trees should be planted as otherwise it will take many years for other types of trees to attain their full height. 2. Trees will be planted along the road side in such a way that there is no direct line of sight when viewed from appoint outside the foliage perimeter. 3. Trees growing up to 10 m or more in height with thick perennial foliage should be planted around the plant. 4. Sensitive species such as magnifier indica should be planted in patches along the entire greenbelt to work as an indicator of pollution. 5. Trees shall be planted staggeredly in each row (minimum three rows encircling the perimeter of the plant). 6. Tree trunk being free foliage up to a height of 2 to 3 m, it is advisable to grow shrubs in front of trees to give coverage to the open portion. 7. Greenbelt will be developed all around the plant area with a width of 10 m. 15
8. Greenbelt will be developed around the plant except wherever buildings and other structures. SOCIO-ECONOMIC ENVIRONMENT Agriculture and sheep breeding are important professions of these people living in the village besides involving themselves in quarrying activity. There is no adverse socio economic impact on the persons in the villages, due to the quarrying operations There is a positive impact of the quarry operations on the socio economic standards of the villagers. The persons from the villages are being given employment in the quarry suiting to their education level and experience. The management is also participating actively in the Corporate Responsibility schemes by grouping with other quarry managements or individually, depending on the merits of the service. SAFETY AND ENVIRONMENT In addition a safety committee will be formed and manned by equal participants from Management and Workers. Personal protection equipment (PPE) will be issued to each worker. Other safety equipments shall be used according to the nature of job involved. The management firmly believes in the concept of safety and environmentally sustainable growth. The authorities and staff are very much concern in Environment issues. The management is going to develop scientifically designed green belt around the premises to mitigate air and noise pollution impacts on the surroundings. The management proposed to monitor ambient air as per APPCB guidelines. All the employees are provided with personal protective equipment such as helmets, hand gloves, safety shoes, goggles and apron as per their place of work. The management will provide safety training to all employees periodically and regularly. POST PROJECT ENVIRONMENTAL MONITORING PROGRAMME In order to maintain the environmental quality within the standards, regular monitoring of various environmental components is necessary. The mines manager will take care of Environmental Management activities with objectives as To implement control/mitigation measures To monitor this implementation process 16
To determine and improve the efficiency of the implemented measures To identify any other unforeseen effect on environment not covered hereby and To inspect and maintain the plantation survival rate, regular cleaning drains, channels and water logged ponds and improve the drainage system and retaining walls over certain timelines. Regular monitoring of various environmental parameters shall be carried out to ascertain the following points: Status of air, noise, water, land pollution within the plant and in its vicinity; Generate data for predictive or corrective purpose in respect of pollution; and To assess and monitor environmental impacts periodically. Project Schedule and Cost Estimates: The envisaged maximum annual production of gravel & Building Stone is estimated to be 31,390.4 m 3 /Annum The cost of the project: 15.0 Lakhs The annual cost estimated for Environmental Monitoring is 5.0 Lakhs. CONCLUSION: The land that is going to be disturbed cannot be reclaimed during the lease period, as the gravel & Building Stone quarry is persisting at further depth and it will take a very long time to exhaust. There is no other significant negative impacts are anticipated as the involved mining activities are very small. All possible measures shall be adopted to control pollution emissions to the minimum and kept below CPCB/MoEF/SPCB standard norms (Air, water, noise standard limits). 17
