EXECUTIVE SUMMARY Mr Saji Abraham, Thekkevattakunnel house, Nagapuzha P O, Ernakulam, Kerala-686 668 is granted a Letterof Intent for quarry permit over an area 0.911Ha situated in Survey No 910/1- 1,917/3B2,917/4-1 of Kalloorkkad Village, Muvattupuzha Taluk, Ernakulam District, Kerala vide Order No.DOE/2594/E2/16 dated 19/10/16 from The District Geologist, Ernakulam 2. INTRODUCTION OF THE PROJECT / BACK GROUND INFORMATION The quarry permit land under application for Environmental Clearance, for quarrying of Granite building stone, situated in Sy.Nos: 910/1-1,917/3B2, 917/4-1 in Kalloorkkad Village, Muvattupuzha Taluk, Ernakulam District, Kerala State. The subject area is owned by the proponent it self. The subject land does not belong to government or is not reserved for any other public purpose. The area is not fit for agriculture as the granite rock outcrops here with the elevated crust of the hilly formation and is devoid of sufficient top soil to facilitate plantation. The area lies away from public properties. The Quarrying plan is being prepared under 3(1) and 9 of rule Kerala Minor Mineral Concession Rule 2015 & the same is approved by the office of the Department of Mining and Geology, Ernakulam. The applicant has to obtain Environmental clearance in accordance with EIA Notification 2006 and its amendments thereafter, from DEIAA, constituted in accordance with the notification dated January 15th 2016 by Ministry of Environment &Forest, Govt. of India. The area is found to have prominent exposure of granite covering the entire lease area. The proponent now strives to obtain Environment Clearance for systematic, scientific and eco-friendly development and production of building stone, with a maximum capacity of 40,000 TPA by carrying out medium scale quarrying by engaging semi mechanized Open cast method of quarrying. The quarrying plan is prepared for an extent of 0.911 Ha.. This application for Environmental clearance covers the whole area and this report is herewith submitted to DEIAA constituted by MOEF for obtaining Environmental clearance. Present Proposal: The present proposal is submitted to the District Level Environmental Impact Assessment Authority, constituted by Ministry of Environment & Forest under the EIA Notification 2006 as per the orders dated 27.02.2012 of the Honourable Supreme Court directing that leases of Minor 1 Minerals including their renewal for an area of less than 5.0 ha be granted/renewed after getting Environmental Clearance from MOEF and recent Notification of January 15, 2016 of MoEF, Govt of India. Need for the project: Rapid growth in infrastructure developments like highways, metros, Technology parks, shopping malls, residential complexes etc has increasingly contributed to exponential domestic demand for building stones & metals. Hence a number of building stone quarries & crushing units with manufactured-sand Units (industries) are coming up in this sector. Building stone is the chief raw material in this sector, for building constructions & road formations. The size & quality parameters for supply of the mineral will be as per the requirements of the user industry. Based on the demand, the applicant intends to mine granite building stone for the developmental projects. As per EIA notification 2006 project proponent is submitting the proposal to get clearance for production capacity of 40,000 tons /annum from District Level Environmental Appraisal committee / District level Environmental Impact Assessment Authority of Kerala constituted by MOEF, GOI for the purpose of operation of mines on grant of quarry permit. The extent of the area under the current proposal is small and the mine shall be worked by semi mechanized method. Employment potential: The Manpower to be employed is around 10 including Mines Manager, Mining Mate & competent staff experienced in operation of excavators, drills, jack hammers in quarrying & allied activities. The employees will be assigned job relating to drilling, blasting, loading, breaking of the building stone and removal of waste & other routine works in the quarry. The working hours at the quarry will be 8 hours/day for 300 days/year 3. PROJECT DESCRIPTION The site is geographically located between North Latitude 9° 57’ 14.20’’ to 9° 57’ 19.73’’ and East longitude 76° 42’ 08.21’’ to 76° 42’ 12.25’’. The project site and buffer zone falls in the Survey of India Toposheet No. C 43Q/9 (Old 58 C/9). In the field studies it is clear that the quarry lease area is falling in uncultivable waste lands, non forest. The area wholly consists of stone / rocky mount. The highest elevation is 125 M and lowest elevation is 80 M above MSL.

Method of Quarrying Semi mechanized method of open cast quarrying(category-B2) Geology of the Area Most of the area is covered by Charnockite, (commercially known as Granite). Charnockite is well exposed in the area. The country rock in the lease area is mainly composed of Charnockite. Occasionally Biotite Gneiss patches are also observed. Dolerite and Gabbro dikes cutting across the country rock is observed in the area . Country rock is folded along the foliation planes and the foliation varies from 600 to 650 . Strike of the foliation plane in the lease area is along NW- SE and moderately dipping towards East. (Source: www.portal.gsi.gov.in) Exploration & Reserves The quarry lease area is exposed with Charnockite outcrop, a quarry was working for a couple of years and exposes the formation. On the north & south sides of the plot also, there are worked out pits which exposes the geological cross section. Hence the deposit in the plot is well proven. No explorations in the form of bore holes are carried out as it is in the proposed area. Moreover, Charnockite is a Plutonic Igneous Rock which is deep seated, and hence no further exploration is required. The reserve is calculated for 3 categories 1. Geological reserves, ie, total reserves available in the entire area 2. Minable reserves available with the ultimate pit limit after leaving the bench width and height 3. Blocked reserves, reserves are blocked due to bench formation and boundary constraints and in buffer zone area. In minable reserves 95% is saleable and rest 5% will be waste. Method of Estimation Of Reserves The estimation of ore reserves is made by conventional parallel cross section method using geological cross section. The geological cross section is prepared at a interval of 30 m across the the ore body. The area of individual litho units in cross section is calculated separately. The volume between the cross section is arrived on the basis of the average area of parallel cross 3 section i.e. ((S1 + S2) / 2) and multiplying sectional interval. And tonnage is arrived at by multiplying by bulk density. Note : Following are the parameters considered for reserve estimation: Category of ore Bulk density Recovery % Charnockite / Granite 2.50 95.00 Waste rock 2.00 - Accordingly the reserves have been estimated and the details of the same are given below The granite /building stone exposures are clearly revealed in and around the lease boundaries. The mineable reserves are arrived after deducting the reserves locked in mines barrier along the boundary. Mineable Reserves 1,36,350 Blocked Reserves 1,38,713 Geological Reserves (Mineable + 3,01,563 Blocked) Production & Development The System or method of working shall be performed as stipulated under Rule 69(1) by formation of benches as per the Metalliferous Mines Regulations, 1961, issued under the Mines Act, 1952. Part of the lease hold area is covered with top soil of scanty thickness. Projected production from the quarry is 133 t/day i.e. around 40,000 tones per year. Benches and Production The topmost horizontal granite bench will be termed as G 1 and benches are numbered as G2, G3, ... G10 etc downwards as depicted below. The topmost bench G 1 above 115 m level holds a mineable reserve of 7375 tonnes where as G 2 locks 6687.5, G3 11150. The reserves from these three levels / benches along with 14,787 tonnes from G4 will give the production requirement of 40,000/- tonnes for the first year. 4 Second year production of 40,000 tonnes shall be met from the remaining reserve of 2600 ton in G4 and 22,125 in G5 along with 15,275 tonnes from the G6 bench. Third year production Like wise the balance reserve of 2,225 tonnes in G6 along with 26,750 tonnes from G7 and 11,025 tonnes from G8 will meet the production for third year.
