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 97,500 CuM/ Annum of Gravel, 52,500 CuM/ Annum of Road Metal and Building Stone (incl. boulders for M-Sand production), for all the five (05) years 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, Gravel and M-Sand 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, Building Stone & M-Sand, by maintaining proper safety standards. o Considering an estimated (proved) mineable reserves of gravel of 4,87,500 CuM, the anticipated life of mine is about 5.0 years. In case of Road metal & building stone (incl. boulders for M-sand), the estimated (proved) mineable reserves are about 48,75,000 CuM and the corresponding life of mine is about 92 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 4,87,500 4,87,500 Road Metal & 48,75,000 48,75,000 Building Stone (incl. M-Sand boulders) TOTAL 53,62,500 53,62,500 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. G. Girish Varma Gravel, Road Metal & Building Stone & M-Sand Quarry 9.75 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 200m to BGL ground 80m interval 2m contour sectional area was total length 372.4 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 O/5. 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 9.75 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 110 m. The lowest contour is 65 M but BGL as consider as 70m(GL) and highest contour is190M in Topo plan for the Quarry, 700m but the hill elevated Page 3 of 10 Sri. G.
