2 ENIVRONMENTAL MANAGEMENT PLAN A. Attach a note on the status of baseline information with regard to the following: To identify with the interrelationship between the eco-friendly quarry operations and environmental management, Environmental monitoring is the primary tool for assessing the prevailing quality of air, water, noise, land etc. It helps in suggesting and taking midcourse corrections, if found necessary. The monitoring shall be carried out at regular interval based on the guidelines of statutory authorities. Monitoring studies for Ambient air quality, Water quality, Noise levels and Soil quality shall be carried-out by the project proponent, as per the approved standard procedures and schedules to record the resultant quality parameters on a regular basis. Necessary funds will be allocated by the project proponent for the same, as well as environmental protection has been identified, as an integral part of plant operation. i. Existing land use pattern including the area already degraded due to quarrying/pitting, dumping, roads, processing plant, workshop, township etc. in a tabular form: The existing Land use pattern of the proposed site is given in the table below: Table 1: Existing Land use Pattern Sl.

Public Buildings, Places of worship and monuments As such there are no public buildings, places of worship and monuments with historical importance within the area or nearby. vii. Attach plans showing the locations of sampling stations The sampling location for ambient air, water, soil and noise in the quarry site is depicted in the Plate-4. viii. Does area (partly or fully) fall under notified area under Water (Prevention & Control of pollution), Act, As per the Water (Prevention & Control of pollution), Act, 1974, the proposed quarry area will fall under the specified area. B. Attach an Environmental Impact Assessment Statement describing the impact of mining and beneficiation on environment on the following over the next five years (and upto conceptual plan period for A category mines) i. Land area indicating the area likely to be degraded due to quarrying/pitting, dumping, roads, workshop, processing plant, township etc.: The said quarrying activity would change the topography of the land area. The proposed land use pattern for the next five years is given below Sl.No. Table 7: Proposed Land use pattern Particulars Area in Sq.m Area in Acres- Guntas Area in % 1 Quarry Area 6, Mineral Storage Yard Waste Dump Yard Quarry Infrastructure Roads/ Country Track

6 Sl.No. Particulars Area in Sq.m Area in Acres- Guntas Area in % 6 Un trenched area Existing Pit 1, Buffer Zone 4, Total 12, ii. Air Quality Quarrying activity would cause minimal impact on the air since it does not involve deep hole drilling and blasting. The major contributor of air borne particles would be the use of machinery for excavation & loading of the quarried minerals. Loading and transport of minerals generate some amount of dust depending upon the climatic conditions such as wind speed, wind direction. However the dust generated will be suppressed by sprinkling water at all loading places etc. iii. Water Quality As such there are no surface water bodies in the quarrying site and nearby locations. And there is no liquid waste generated from the quarrying activity. iv. Noise levels The noise level in the quarrying area with loading, drilling & cutting activities would be likely to increase. The workers shall be provided with ear plugs and ear muffs. v. Water regime An artificial drainage system will be developed by the side of the quarrying block and dump yard so as to channelize the water to move further to natural slopes. The anticipated accumulation of ground water in the pit will be pumped out when the pit is deepened below the existing surface. vi. Socio-economics The proposed project will not affect the welfare of the local people, instead it will support for improving the local socio- economic conditions of the people in the surrounding region by providing direct employment and indirect employment opportunities like workshop, canteen, drivers and etc., vii. Historical Monuments As such there are no historically important monuments in the vicinity of the proposed quarry area.

7 C. Attach an Environmental Management Plan (supported by appropriate plans and sections) defining the time bound action proposed to be taken with sequence& timing in the following areas (or diagrams should be used: In order to implement the proposed environmental management program, periodical monitoring as per statutory guidelines and mid-course corrections/actions, if required based on the environmental monitoring results, management will establish environmental management cell for successful implementation. The roles & responsibilities are clearly defined among the personnel within the environmental cell. The responsibilities of personnel are given below: a. Quarry Manager: Will be responsible for overall planning, execution and management of environmental protective measures and monitoring of parameters in the site area. b. Supervisor: Will be overall in-charge of monitoring of Environmental parameters and effectiveness of environmental protective measures taken and decide about the additional protective measures in safeguarding the overall ecology and environment. c. Skilled and Unskilled workers: Will be responsible for maintenance of plantation, retention walls, roads, drainages, fences, equipment, plant based on the superiors instruction. Quarry Manager Supervisor Skilled Workers Unskilled Workers i. Temporary storage and utilization of soil The top soil generated during the course of quarrying will be removed separately and stored in a designated place within the area and will be utilized for Afforestation purpose as and when required. ii. Reclamation of land Subsequent to the working up to the Ultimate pit limit defined for the mineable reserves, no whole or part of the pit will be back filled or reclaimed because entire deposit will not be exhausted. Hence no reclamation or back filling is proposed. However a part of the quarry will be used as rain water harvesting pond.

8 iii. Afforestation programme for first five years Afforestation programme in the quarry site area is not feasible since the entire area is rocky hillock. However plantation will be carried out along the approach road, in the bund around the quarry site and nearby village roads. Rain tree (Samaneasaman), Honge (PongamiaPinneate), Jatorpha, Ficusriligosa (Arali), Ficusbenghalensis (Aathi), Neem (Azadirachtaindica). It is proposed to plant with 60 saplings of each quarry annually. Anticipated survival rate is 70-80%. Table 9: Afforestation Programme for first five years Year Numbers Saplings Species 1 st 60 Rain tree (Samaneasaman) 2 nd 60 Honge (PongamiaPinneate), 3 rd 60 Jatorpha, Ficusriligosa 4 th 60 (Arali), Ficusbenghalensis 5 th 60 (Aathi) Neem TOTAL 300 (Azadirachtaindica) iv. Stabilization and vegetation of dumps along with waste dump management year wise for the first five years (and upto conceptual plan period for A category mines). The dumps will be stabilized by constructing a retaining wall at the sloping end of the dump. Suitable plantation will be done at the peripheral of the dump slopes to check the soil erosion and the same will be followed for the following years as well. v. Measures to control erosion/sedimentation of water courses: The proposed quarry area does not have any rivers or water bodies in the vicinity of 5 Km radius. vi. vii. viii. Treatment and disposal of water from mine: No water is discharged from the quarry except sewage water from office which will be discharged into septic tank followed by soak pit. Measures for minimizing adverse effects on water regime: Water in the regime will not be affected since an artificial drainage system will be developed by the side of the quarrying block and dump yard so as to channelize the water to move further to natural slopes. The anticipated accumulation of ground water in the pit will be pumped out when the pit is deepened below the existing surface. Protective measures for ground vibrations/air blast caused by blasting: The proposed quarry is carried out by using jackhammer holes with wire saw cutting for cutting of granite form the blocks. Therefore blasting is not required for the proposed quarry and the vibration caused is very negligible.

9 ix. Measures for protecting historical monuments and for rehabilitation of human settlements likely to be disturbed due to mining activity. As such there are no historical monuments and no human settlements are affected by proposed quarrying activity. x. Socio economic benefits arising out of mining. Quarrying sites are generally remote and under developed. Standard of living of the people in such areas is normally low, therefore due to industrial activity like Quarrying, local population within the buffer zone are to be benefited by direct and indirect employment opportunities created by the Quarrying activities. People will also be benefited for the facilities developed due to Quarrying activity. Quarrying activity contributes towards economic up-liftment by way of job opportunities in the region. Hence there will be an improvement in quality of life in the area. Quarrying activity will also boost the ancillary industries, business and market establishments. xi. Monitoring schedules for different environmental components after the commencement of mining and other related activities (for A category mines only). It is not applicable since the proposed quarry project falls under category B2. Sl No. 1 D. Estimated Environmental Protection Cost in terms of economic viability of the project. Expenditure proposed for Environmental protection activities: It is proposed to invest an amount of Rs. 13,22,472 for five years towards environmental action plan and the details of the same are given below: Table 10: Proposed Costs for Environmental Protection Activity Year I Year II Year Total Year IV Year V III Budget Fencing (All along the boundary) 34,440 34,440 68,880 2 Safety Bund 1,20,000 60,000 30,000 2,10,000 3 PPE s 15,000 15,750 16,538 17,364 18,233 82,885 4 Dust Suppression 75,000 78,750 82,688 86,822 91,163 4,14,423 5 Environmental Monitoring 25,000 26,250 27,563 28,941 30,388 1,38,142 6 Occupational Health & Miscellaneous 25,000 26,250 27,563 28,941 30,388 1,38,142 7 Afforestation 30,000 30,000 15,000 15,000 15,000 1,05,000 8 CSR Activities 33,000 33,000 33,000 33,000 33,000 1,65,000 TOTAL 2,37,440 2,44,440 3,22,352 2,70,068 2,48,172 13,22,472
