Proposed Limestone Slabs Quarry By Sri V. Venkata Krishna Reddy Ogipur (V), Tandur (M), Vikarabad (D) Environment Management Plan 1. INTRODUCTION In a developmental activity like Limestone Slabs mining, all the exercises must co-exist satisfactorily with its surrounding condition so as to minimize the adverse impact on the environment. To control the likely adverse impacts and to achieve this goal, it is necessary to prepare an Environmental Management Plan, which has to be implemented by the proponents, in order to achieve environmental protection along with production profits. Hence, Environmental Management Plan has been prepared for submission to State Environmental Impact Assessment Authority / State Expert Appraisal committee as per EIA notification 2006 and the amendments thereof for clearance of the proposed mining area. Sri V. Venkata Krishna Reddy has filed an application for quarry lease for Limestone Slabs over an extent of 0.606 Ha.in Sy. No: 49 of Ogipur Village, Tandur Mandal, Vikarabad District, Telangana and the Deputy Director of Mines and Geology, Hyderabad has granted the quarry lease in favor of Sri V. Venkata Krishna Reddy for a period of 10 years vide notice No. 2010/QL/VKB/2018, Dated 04.08.2018. Quarry Plan was approved by Deputy Director of Mines & Geology, Hyderabad region vide letter No: 3656/QP/VKBD/2018, Dated 24-12-2018. 2. PROJECT PROPONENT Sri V. Venkata Krishna Reddy, is a Quarry Contractor and mineral trader. He is doing the business of mineral trading for the past few years and is one of the key suppliers of Limestone Slabs to the industries from this region. Having significant experience in the mineral trading and Quarry of Lime Stone Slabs, to expand his business activities, applied Quarry Lease for Lime Stone Slabs over an extent of 0.606 Ha. In Sy. No: 49, Ogipur Village, Tandur Mandal, Vikarabad District, Telangana. 2.1 Project Location and Accessibility Limestone Slabs Quarry is proposed at Ogipur Village, Vikarabad District, Telangana.

GEOLOGY 3.1 Topography: The entire Quarry lease applied area is a plain ground with a gentle slopes towards east. The assumed bench is taken at Boundary Point No.4 with reduced M.S.L of 435.5m. The minimum R.L of 435m is observed at the eastern side of the applied area. The applied area is a barren land and the rest sides being barren lands with working quarry of Limestone Slabs on north, west and south sides of the applied Q.L area. The lands to the east are open lands. There are approach roads from the applied area connecting to the road going to Chatrasala from Ogipur on northern and southern side. 3.2 Regional Geology: The limestone deposits occurring in the area belong to man Bhima Basin group of Upper Proterozoic period. The rocks of Bhima basin rests over the rocks of Archean basement with a marked unconformity comprise of conglomerate and grit in the granitic terrain. They are considered equivalent of Vindhya systems. The following Stratigraphic sequence has been identified in the region: Geological Age Formations Recent Soil, Alluvium Bhima Group Upper Bhirnas(Flaggy Limestones) Middle Bhimas(Massive Limestones) Lower Bhimas (Shale & Sand stones) 3.3 Local Geology The limestone deposits occurring in Vikarabad district belong to a group of rocks known as Bhima series. The main Bhima basin is in the Bijapur and Gulbarga districts of Karnataka. Only a small eastern extension of the basin is exposed in Telangana in Vikarabad district. Within the quarry lease applied area the limestone occurs as grey to dark grey limestone and pink shale. Most of the area within the quarry lease applied is covered by black soil (ranges 1.0m to 1.25m) with outcrops of limestone here and there the geology of the area has been constructed based on surface geological mapping and sub-surface data of the adjacent working quarries .The general strike of the formation is NW-SE with beds usually dipping west and south west at low angles of 20 to 30, as observed from the outcrops exposed in the western side of the applied quarry lease area. The general geological succession in the area is given below: 5 Proposed Limestone Slabs Quarry By Sri V. Venkata Krishna Reddy Ogipur (V), Tandur (M), Vikarabad (D) Environment Management Plan Litho unit Thickness Soil 1.00m to 1.25m Massive limestone 0-25.5m Pink Shale Not known In the subject applied Q.L area the massive thick bedded limestone occurs over a thickness up to 5.0 m followed by the moderate to thin bedded limestone over a thickness of max. 6m and followed variegated limestone of reddish colour and followed by pink shale. 4. EXPLORATION/PROSPECTING: No trial pits have been made in the subject Q.L applied area. No boreholes of any type have been carried out in the subject area and have been proposed in the Quarry Plan. 5. RESERVES The ore body of Limestone Slabs is occurring as massive flat body below the black soil/thick bedded Limestone beds. The area spreads over an average length of 97.5 m and width of 62.5m.The thickness of the ore body not uniform and is varying with thickness ranging from 5.8m to 6.0m beds. The Limestone Slabs is occurring as a massive body below the general ground level below the black soil of 1.0m-1.25 m thick and thick bedded limestone of 4.60m to 5.0m thick. The quality of Limestone Slabs ore changes with depths. The bottom 6.0m thick light grey coloured Limestone Slabs (Parchi) is of low grade.
