In Principle of quarry lease called for by Department of Mines and Geology, Government of Andhra Pradesh vide Notice No. 10168/R1‐1/2011 dated 04.07.2011 subject to submission of the approved mining plan within period of 6months. It is proposes to conduct semi mechanized open cast method quarrying for multi color granite production of 1200 m3/annum from the lease area. Mining plan is approved by the Zonal Joint Director of Mines and Geology, Visakhapatnam, Government of Andhra Pradesh vide Letter No. 2662/MP/11 dated 30‐7‐11. Capital proposed for the quarrying is Rs. 13 Lakhs. M/s. Excellent Granites is conscious of its environmental responsibility towards the society in minimizing the pollution load due to this project and accordingly decided to carry out the Environment Management Plan. The objective of preparing environment management plan is to delineate effective measures to control and to mitigate the environmental pollution. This report presents the environment management plan, detailing the environmentally sound technology and the measures needed to contain and mitigate the anticipated environmental impacts due to the project. 1.1 Granite and its uses Granite is a very common intrusive igneous rock. It is light‐colored granulose plutonic rock composed of the minerals feldspar, quartz and biotite & muscovite mica. These minerals make granite white, pink, or light grey. Granite also contains small amounts of dark brown, dark‐green, or black minerals, such as hornblende and biotite mica. Granite is very hard and dense. It can be readily cut into very large blocks and it takes an extremely high polish. The name granite is derived from the Latin word granum, which means 1‐1 Team Labs and Consultants Excellent Granites Environment Management Plan grain, an obvious reference to the granular texture of granite. The average density of granite is between 2.65 and 2.75 g/cm3, with a compressive strength of above 200 Mega Pascal (MPa). Uses Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. With increasing amounts of acid rain in parts of the world, granite has begun to supplant marble as a monument material, since it is much more durable. Engineers have traditionally used polished granite surfaces to establish a plane of reference, since they are relatively impervious and inflexible. Granite tables are used extensively as a base for optical instruments due to granite's rigidity, high dimensional stability and excellent vibration characteristics. Rough‐cut and polished granite is used in buildings, bridges, paving, monuments and many other exterior projects. Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other practical and decorative features. Presently, cut and polished granite slabs of 20 mm thickness are preferred for flooring, while tiles of 10 or 12 mm thickness are used for cladding. 1.2 Mining Method The mining operations are in the view of shallow nature of the deposit; open cast mining method shall be adopted in a semi mechanized manner by forming benches of 6m height. Hydraulic excavator and compressor jack hammers were used for cutting the rock. 1.3 Mine Location M/s. Excellent Granites proposes to conduct semi mechanized open cast quarrying for colour granite average production of 1200 m3/Annum. The proposed Quarry lease area of 2.825ha in Survey No. 388, Binnala Village, Kanchili Mandal, Srikakulam District, Andhra Pradesh. The quarry lease area falls in the Survey of India topo sheet no. 74A/12 on Latitude 19° 1'35.55"N and Longitude 84°35'6.27"E with an elevation of 35m. The nearest village is Binnala at a distance of 0.5km from the QL area in SW direction. Nearest Railway station is Jhadupudi at a distance of 3.0km in NE direction. Nearest town is Palasa at a distance of 33km in SW direction. NH‐5 Road Srikakulam to Bhubaneswar is passing at a distance of 2.9km from the QL area in SE direction. Arujunapuram‐ Yekkala village road is passing at a distance of 0.7km in West direction. The lease area can be accessible through a cart track. Bahuda River is 1‐2 Team Labs and Consultants Excellent Granites Environment Management Plan flowing at a distance of 8.7km from the QL area in NE direction. Jalantrakota reserve forest is at a distance of 2.9km in SW direction. Shandhabhuja reserve forest is at a distance of 5.3km in NW direction. Andhra Pradesh and Orissa interstate boundary is at a distance of 0.3km in NE direction. There are no national parks, wildlife sanctuaries and critically polluted areas observed in 10km radius from the quarry lease area. Quarry lease location map is presented in figure 1.1. Details of the quarry lease area are presented in table 1.1. Table 1.1 Details of the Lease area Area in Ownership of State & District Mandal Village Sy.

The quarry lease area is plain land with occupied of colour granite jutting out to the surface. At place the area is covered by a thin veneer of soil which consists of weathered granite in the form of morrum. The maximum RL of the area is 54 m in the Northern part and the minimum RL is 50m in the southern part of the area. 3.0 Regional Geology It is a part of Eastern Ghat group of rocks consisting of charnockites, khondalite and granitoids a variety of hybrid rock formed by the interaction of intrusive granite into the khondalite. The Eastern Ghat group attains a maximum thickness in the Ganjam‐Cuttack tract. It occurs as ridges trending NE‐SW. The Eastern Ghat belt exhibits high grade metamorphism as evidenced by the presence of garnet and silliminite. The charnockite shows intrusive relation toward khondalite and under gone post magmatic changes. Felspathic bands are common due to granitisation. 3.1 Local Geology The terrain in and around the area is of undulating in nature. The major portion of the area is occupied by big of color granite jutting out to the surface to a height of about 4‐5m. The main rock exposed in the area consists of granitised/ Migmatised charnockite, with phenocrysts of feldspar in a fine ground mass. The texture is porphyritic and gneissic type. 3.2 Brief description of litho units The main litho unit present in the applied area is granitised/ Migmatised charnockite in the form of boulders. The colour is blue in some places and light blue in some. The minerals present are Silliminite, Garnet and Quartz. 4.0 Exploration Present Status: The area was initially mapped and geology was plotted on the geological plan. Subsequently, surface samples were collected and based on the market response mining was started. The area is virgin however the adjacent area in Orissa is being for road metal and the granite is exposed there in quite a few places. The granite occurring in the area is similar to the one being worked may be well accepted in the domestic and international market. 1‐6 Team Labs and Consultants Excellent Granites Environment Management Plan b) Future Programme Future exploration consists of opening a few working faces just to confirm the color consistencies. However the boulders exposed in the area good indication of a boulder deposit. 5.0 ESTIMATION AND CALCULATION OF GEOLOGICAL RESERVES Based on the information obtained from the boulders and exploratory openings in the adjacent area, the ‘proved’ category reserves are estimated to a depth of 5m from the surface. The average length of the deposit is taken as 205m and the average width is taken as 75m depending on the granite exposed in the area. Further a 5m depth from the base of the proved one, is considered for the estimation of the reserves under the ‘probable’ category and 5m zone below the probable zone is considered for estimation of reserve under the ‘possible’ category. The reserves available in the lease are complied as stated below table 1.3.
