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 15 th 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 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 of the Honourable Supreme Court directing that leases of Minor 1

3 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.

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 60 0 to Strike of the foliation plane in the lease area is along NW- SE and moderately dipping towards East. (Source: 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

5 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 Waste rock 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 + Blocked) 3,01,563 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, 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 , G 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

6 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. BENCH RL QUANTITY G G G ,000 G G G ,000 G G G ,000 G G G TOTAL Method of Quarrying The quarry will be working with conventional open cast mechanized method. Based on the mode and method so adopted and taking into the consideration of geological parameters of the granite / Charnockite body, the quarry pit is so designed such that the height of the bench is kept about 5.0 m and the width is also kept min. 5.0 m, maintaining 45 o pit slope. Mode of operation (quarrying) will be semi mechanized open cast Drilling will be done by using Jack hammer drills of 32 mm dia holes For blasting, Nitrate Mixture type of explosives (Class 2) will be used Initial bench height will be 2.5 m, at the final (ultimate) stage bench height, it will be maintained 5.0 m and bench width will be narrowed to absolute necessity At final stage the slope of the bench will be maintaining 65 o slope. (Since granite is hard rock) 5

7 Boulders so generated subsequent to the blasting, this will be broken with the help of the rock breakers Loading of fragmented material into the Tippers with the help of Excavators. Drilling & Blasting: Since the bench height needs to be maintained 5.0 m, blast hole will be by jack hammer where the diameter is normally 32 mm and the depth of the hole is 2.5 to 2.6 m. Blasting pattern is generally square or staggered with burden ranging from 0.75 to 1.00 meters and spacing of 1.0 to1.2 meters. Usually single / double row of holes is blasted along free face to achieve optimum powder factor, best fragmentation and minimized adverse impacts on account of blasting. Maximum holes blasted per day are 30 to 40 with normal delay detonators to mitigate adverse impacts such as air blast, throw and the ground vibration. Holes are electrically detonated using electric detonators. Nitrate mixture (Class-2) types of explosives are used for blasting with 20 to 25 percent, proportion of primer/ booster cartridges and rest as column charge. About 2 to 3 kg of explosives are loaded in 32 mm diameter holes. And powder factor ranging between 7 to 8 tons per kg of explosives is achieved Lessee is having the Explosive license. A copy of the explosive license is enclosed as Annexure 9 in the Approved Mining Plan. Loading and Hauling: Loading of the building stone blocks will be done mechanically to tippers of 10 tons capacity and transported from the quarry to the stockyard and mineral rejection/waste will also be handled mechanically. In the quarry the road will be maintained with 1 in 16 gradients. Sufficient number of bunds and parapet walls will be made all along the quarry haulage roads wherever necessary in order to maintain safe working conditions by using the waste generated during the course of quarry operations. Solid waste Management: Over burden and Intercalated waste is to be handled during the quarrying operations is less as the entire area is almost a rocky terrain. An estimated quantity of around 2150 MT is required to be handled during the proposed plan period. The recovery loss constitutes the waste generated and is due to the incidental to quarrying and the intercalated waste material, if any. This will be stacked outside the boundary of lease area for sale for construction of compound wall etc. Hence a zero waste management of mineral is proposed. The dust generated will be suppressed by water spraying and removed as slime collected in de-silting pits. Hydrology: 6

8 The general ground water table in this area is m below the general ground level during the summer and around 8-15 m during monsoon. Since the quarry falls on the hillock, and the ground water table is m below the general ground level, none of the quarry workings will touch the water table. The workings are very much above the ground water tab le. Water resources in this area are ground water and rainwater or from kaliyar river. The area receives copious amount of rainfall about 3200 mm annually on an average. The level of water table in the open wells is shallow i.e. about m depth during the summer and 8 15 m during monsoon from the general ground level. The kaliyar river that flows at a distance of 4.7 KM is a perennial water course. The entire storm water flows through the minor watercourses and joins the river. The drainage pattern in this area is dendritic in nature. 4. SITE ANALYSIS Connectivity The quarry lease area is easily accessible in all seasonal conditions. The quarry lease area is around 51 KM from Aluva railway station, 17 KM from MC road.nedumbassery International Air Port (Cochin) is at 50 KM on the west. The permit area of Ha consists of Sheet rock, Non forest lands with massive granite out crop forming a hillock. The proposed land use pattern of the core zone is given below: Present land use pattern: The present land use and terrain patterns of the study area can be observed as follows: Present land use pattern (Area in Hectares) Type of Land Use Area put on use at start of the plan Area under quarry pit 0.30 Overburden/waste dump - Infrastructure(Workshop, Admin and Bldg) - Roads - Greenbelt - Undisturbed area Total Ha The proposed area to be worked during the three year is shown in the year wise Production & Development plan. The future proposed reclamation is by suitably sloping the quarry benches 7

9 at the end of quarry lease period of the quarry and by way of afforestation on the dumps and open places outside the working and lease areas. Existing Infrastructure: The construction of temporary structures for quarry office, Rest shelter, First aid station, sanitation & etc., are proposed to be provided out side the Quarry lease on the south on way to the quarry. The details are collected for the core and buffer zone of the quarry lease. The drinking water, electricity and primary education facilities are available in almost all the villages. The police station, post offices, dispensary facilities, phones, educational facilities etc are available in the village itself. There is good approachable weather roads present in the buffer zone of the area.. There are no sensitive areas for ecological reasons. Necessary precautionary measures in the form of infrastructure shall be provided during the course of quarry operations. A parapet/retaining wall as a fence shall be constructed all along the lease boundary to avoid trespassing of men & animals. 6. PLANNING BRIEF Conceptual Quarry Plan: As per guidelines, the conceptual plan period is to be prepared only up to the end of permit period in case of B category quarry. Manpower Projection: The man power of quarry includes Quarry manager/foreman, Mine mate supervisors, skilled and unskilled labours and other staff etc. As far the socio-economic is concerned from the quarry activity nearby villagers shall get 7 direct employments. The proposed quarry activities also shall bring the positive change in the villages as the quarry shall provide socioeconomic activities in the region. Land use planning: The Land use and land cover for the ensuing plan period and conceptual period. Description As on date Lease Period Ha End of Conceptual period Ha Area under Quarrying Buffer zone (Green Belt) Area for future use/undisturbed Total

10 Green Belt Development : It is proposed to develop a green belt outside the lease area. The existing rubber plantations on way up the lease hold in the Lands of the lessee will be nursed further. In addition, both sides of the haul road outside the lease area will be planted with suitable avenue trees. It is proposed to carry out afforestation by planting saplings of fruit yielding / flowering trees. Proper care will be taken for protection & growth of these saplings. The afforestation to be taken up will provide requisite floral biodiversity. At the end of the plan period non rocky area if any will be afforested and wherever possible and along roadsides afforestation will be proposed of area is earmarked for afforestation during the proposed plan period. During the afforestation work, the combination of different species shall be planted. This selection shall be made on the basis of the local plant growth in this surrounding area. It is always better to plant mixed species together. Guidance from the local forest department shall be taken in the selection of species and their maintenance. The plantation work requires considerable quantities of seeds, seedlings and saplings of different species: Nursery stock for this plantation will be available from the local forest and Horticulture department. Plantation crops like Rubber, Pepper, Arecanut, Coconut, fruit bearing trees like Mango, other plants such as Mahagoni, Rain tree, Bougainvillea, Red Palm and local species with thick foliage to arrest dust dispersion due to movement of vehicles will be planted Assessment of Infrastructure Demand: The existing road network will be sufficient to meet the proposed capacity; however required infrastructure for transport within the leasehold area will be further strengthened and improved. No new routes or alternations are required in this regard. Amenities/Facilities Applicant proposes to employ about 10 persons. This along with non-direct employment will have a positive impact on the socio-economic conditions of the surroundings as most of the work force employed will be from the nearby areas. Local persons will be hired for meeting the requirement of truck loading, plantation, construction of check dams, retaining walls etc. The benefits due to quarry to the local population will be in the form of Direct and indirect employment opportunities. 6. PROPOSED INFRASTRUCTURE The quarry permit area of Ha is Private Patta land. The proposed method of quarry operation will be semi mechanized with jackhammer drilling & blasting with tipper/tractors for 9

11 internal transport. The lease area does not have any public roads, railway lines, telephone lines, public buildings etc. Present infrastructure will meet the requirement of the project. The conditions of the roads in the buffer zone are unlikely to be impacted due to the proposed minor scale operation. The project authorities in association with the district administration will also contribute to development & maintenance of roads. Social Infrastructure: The quarry lease area is easily accessible in all seasonal conditions. The nearest rail head on Broad Gauge is Aluva railway station, which is at a distance of 51 KM approximately on the north west and the MC road leading to Aluva is only 17 KM from the quarry site. The nearest Air port is Nedumbassery International Air Port (Cochin) and is at a distance of 50 km. Drinking Water Management : The Right canal of Muvattupuzha valley irrigation project that flows at a distance of 0.65 KM on the SW is a water course. The entire storm water flows through the minor watercourses and joins the river. There is no possibility of disturbance of water shed. Rain water will continue to flow in the same direction as it is in existence. Since the water is not withdrawn (from any source outside the lease area) for quarry purposes for quarrying operations no adverse impact is foreseen on the existing water regime. The rainwater stored in the pits shall be utilized for mitigating dust and other activities. The surface water in the buffer zone is in the form of seasonal rainfall and the ground water bodies encountered below depth in the area from the surface level. The area is small; so far no report on hydrological studies has been carried out in the area under question. There is no potential of acid mine drainage. The drinking water is available from nearby bore wells and water can be stored into sintex tanks. During the course of quarry operation no diversion of water course is considered as it doesn t exists. Sewage System : The existing watercourses shall not be disturbed and rain water will continue to flow in the same direction. Check dams shall be constructed in the nallahs of the buffer zone and retain walls constructed by the side of the O.B. Dumps, water will percolate in the premises of the quarry area. There is no generation of domestic sewage. Industrial Waste Management : There is no generation of affluent/toxic substance; hence treatment of quarry water doesn t arise. 10

12 Solid Waste management : Over burden and Intercalated waste is to be handled during the quarrying operations is less as the entire area is almost a rocky terrain. An estimated quantity of around 1300 m 3 top soil and 6,817 MT ( 5 % 0f 1,36,350 ) is required to be handled during the proposed plan period this waste material will be temporarily accommodated in the adjacent area outside the lease hold, owned by the lessee on the southern part of the lease hold. Power requirement and supply : There will not be any requirement of power supply to the project site. The quarry activities like drilling, loading, unloading by excavators and transportation shall be carried out with diesel as motive power only during day time. As such for operation of the quarry no power supply is required as the HEMMs will be operated by HSD. The power supply for office will be met through Kerala State Electricity Board. 7. REHABILITATION AND RESETTLEMENT PLAN The primary objectives of reclamation are to restore the affected area to the original state as near as possible. Quarrying will alter the surface profile in the area by way of excavation and surface dumps. This may lead to water pollution, silting of agricultural lands; air pollution etc if proper care is not taken. The various reclamation proposals planned during the plan period and further will include proper formation of roads, working of benches with safe angle of slope, installation of effective drainage system, prevention of erosion and excessive run off & re-vegetation or afforestation. ENVIRONMENTAL PROTECTIVE MEASURES The proposed QL area is totally barren except sporadic retarded seasonal growths of grass and bushes. No tree grows in the lease hold as the area outcrops granite.
