Sri. S. Sankara Rao Road Metal, Building Stone and Gravel Quarry 6.00 Ha. of Non-Forest Govt. Land, Sy. No. 293, Reddipalli Village Padmanabham Mandal, Visakhapatnam District, Andhra Pradesh EXECUTIVE SUMMARY o Sri. S. Sankara Rao, is a resident of Reddipalli Village in Visakhapatnam district, involved in the business of mining and trading of building stone, gravel etc. He was granted a quarry lease for extraction of Road Metal, Building Stone and Gravel, over an extent of 6.00 Hectares, in Non-Forest Government Land, bearing Sy. No. 293 of Reddipalli Village, Padmanabham Mandal, Visakhapatnam District, Andhra Pradesh, for a period of 10 years, by the Deputy Director of Mines & Geology, Visakhapatnam, vide Notice no: 370/Q1V/2016 dated 14/03/2016. Assistant Director of mines and Geology lessee executed proceeding no. 2583/Q/ 2015 dated 23/08/2016 in favor of Sri. S. Sankar Rao and Proc. No 13524/R1- 3/2016, dated 14-12-2016 of the Director of Mines and Geology, Andhra Pradesh. o The proposed Road Metal, Building Stone & Gravel Quarry Area is near Reddipalli Village, in Padmanabham Mandal of Visakhapatnam District, Andhra Pradesh, and is part of Sy. No. 293 of Reddipalli Village in Padmanabham Mandal of Visakhapatnam District. The proposed quarry area has been notified in favour of the Proponent. o The proposed Road Metal, Building Stone and Gravel Quarry Lease area, is located between Latitude of 17° 59' 53.75" N & 18° 00' 11.98" N and Longitude of 83° 20' 37.04" E to 83° 20' 51.32" E. The proposed quarry lease area is surrounded by other gravel, road metal and building stone quarries. There are some existing mining leases as well as newly notified areas, on all the sides of the proposed quarry lease area, except on the north side. o Within 500 radial distance of the proposed quarry, there are three (03) with a combined extent of 24.84 hectares, and all these three leases were granted after 09th Sept. 2013 and hence, as per EIA Notification 2006 Amendment dated 01st July 2016, all these Three (03) leases become part of the cluster, for preparation of the cluster EMP. The total extent of the cluster, including the above proposed lease area, the total extent will be 30.84 Ha. < 100 Ha. Hence classified under B1 category. o There is no agriculture on the proposed mining land. o The Proponent had applied for Environmental Clearance to State Environment Impact Assessment Authority (SEIAA), Andhra Pradesh and they have issued the Terms of Reference (ToR), for carrying-out Environment Impact Assessment (EIA) studies and preparation of an EIA/ EMP (Environmental Management Plan), for the proposed Gravel, Road Metal and Building Stone Quarrying, vide Lr No. SEIAA/AP/VSP/MIN/05/ 2018/601-181 dated 03.05.2019.

No. 293, Reddipalli Village Padmanabham Mandal, Visakhapatnam District, Andhra Pradesh o M/s Global Environment & Mining Services, Hospet, Karnataka, have been retained by the Proponent to carry-out EIA Studies and preparation of EIA/EMP report. The baseline data collection (environmental monitoring) was conducted as per MOEF & CC norms for Post-Monsoon Season (Jan. 2020 to Mar. 2020). o Present summary is of the EIA report as per TOR and has been prepared as per generic structure given in Appendix III of EIA notification 2006 by MOEF & CC. o It is proposed to mine about 1,20,000 CuM/ Annum of Gravel (max.), with an average annual production of 91,200 CuM/ Annum. In case of Road Metal and Building Stone, first two years of operation, there will not be any kind of extraction of road metal and building stone. In the next three years, i.e. from 3rd year to 5th year, the production of road metal and building stone, is at a uniform rate of 48,000 cum/ annum during the plan period. The anticipated recovery (saleable production) is 100% of the mined quantity, resulting in ZERO waste. o The method of mining is by semi-mechanized open cast mining method, with controlled blasting. o Road Metal, Building Stone and Gravel are important materials for the Construction Industry, both in building construction (houses, apartments, commercial buildings etc.) and also various infrastructure works (bridges, roads, irrigation tanks etc.). o This is a new project & RQP has prepared the mining plan for mining of Gravel, Road Metal and Building Stone, by maintaining proper safety standards. o Considering an estimated (proved) mineable reserves of gravel of 6,00,000 CuM, the anticipated life of mine is about 6.58 years. In case of Road metal & building stone, the estimated (proved) mineable reserves are about 15,00,000 CuM and the corresponding life of mine is about 31.25 years. As per the approved mining plan, there is no waste generation of any kind. o The Estimated Geological and Mineable Reserves, are as under: Description Geological Reserves (CuM) Mineable Reserves (CuM) Gravel 6,00,000 6,00,000 Road Metal & 15,00,000 15,00,000 Building Stone TOTAL 21,00,000 21,00,000 o Local Geology: Present area constitutes a part of khondalite with chrnockite intrusion zone represented mainly of charnockite and basic granulites with miner inclusion bands of iron formations. The litho logically the lease area is underlain Page 2 of 10 Sri. S. Sankara Rao Road Metal, Building Stone and Gravel Quarry 6.00 Ha. of Non-Forest Govt. Land, Sy. No. 293, Reddipalli Village Padmanabham Mandal, Visakhapatnam District, Andhra Pradesh by khondalite and charnockite, which is looking greasy, dark colored with domination of hypesthene and blue quartz mineral in it combination as associate. o The charnockite in the area forms as elongated pagoda dome, elongated shape, moderate slopping towards three directions and very gentle sloping towards south and plunging towards SW direction. The rock is medium to coarse grained texture constitute with composed of greasy vitreous quartz, hypersthene. Orthoclase and plagioclase with or without any lineation and foliation in this massive rock body. The rock is massive, with widely spaced vertical nature, sub- vertical joints trending in NE – SW direction. It is observed that sheet joints are rarely present. Owing to its compact and hardness, charnockite withstand to weathering and form huge, steeply slopping dome shaped hill structure on eastern side in this area. Very gentle slope with cover of gravel along with red soil nature. o Hypersthene Granulites are occurring in most of quarry lease area as a mound. This rock type is formed as sheet rock at higher altitudes and a thin layer of soil is covering granite sheet rock at lower reaches i.e., is on SE side of the lease area. This rock type might have been derived from high grade granulites fancies metamorphism of a pile of volcanic intrusive. One geological sections were drawn across the trend of the formation from top 70m to BGL ground 50 m interval 1 m contour sectional area was total length 560 m and these sections are enclosed as plate no 3 and 4. o The Eastern portion of the lease area covered by weather material and soils by a thin 0.5m layer. The layer may cover 10cm to 200cm thick layer on the rocky body. Road metal & Building stone material call geological term for material used for Road metal & Building stone is Hypersthenes granite and granulites and it is also called as Charnockite. Most quarry lease area is formed for hypersthenes granulites as a massive sheet rock at higher attitude with in layer of soil in whether material quarry lease area. At lower reaches and eastern side the rock is exposed height of 65m from normal ground level of base 70 on MSL at western side on it is extending further depth below 10m the normal ground of base level as sheet rock. The rock mass of these areas is being marketed as road metal as fine to medium grain size massive nature is sores dark gray color. o Topography of the site: The area is located on Toposheet No. 65 N/8. The quarry lease area is located on a hill raised with an elevation 70m above western Flank area base level as 70m and little higher, maximum 180 m above the ground level MSL within the quarry lease Sy. No. 293 total area 6.00 hectares working in this quarries along the present quarry, to north east to eastern side, at present the working was undertaking below surface, with Topo relief in SW and West direction 20 m. The lowest contour is 45 M but BGL as consider as 50m(GL) and highest contour is 70 m in Topo plan for the Quarry. Page 3 of 10 Sri. S.

No. 293, Reddipalli Village Padmanabham Mandal, Visakhapatnam District, Andhra Pradesh o The area constitutes a part of southern Flank hilly zone region. The slope is gentle towards south west, South and west, with the maximum height of the hill in central top of hill averagely high 83 m above at knob area shows above 53m on north side portion between the grids north height of 43 to 50 and less higher towards south side as 75m.
