5 1 Introduction The report discusses the management plan for mitigation of adverse environmental impacts and increases the beneficial impacts due to mining of Laterite The environmental impacts can be categorized as either primary or secondary. Primary impacts are those, which are attributable directly to the project, secondary impacts are those, which are indirectly induced and typically include the associated investment and changed pattern of social and economic activities by the proposed action. The objective of preparing environment management plan is to define effective measures to control and to mitigate the environmental pollution. This report presents the environment management plan, detailing the environmentally sound technology and the measures needed to mitigate the anticipated environmental impacts due to the project. Sri G. Balreddy Mg. Partnet of M/s.

9 2 Reserves Estimation and Life of Mine Geological traverses in the quarry and the study exposures in the vicinity of quarries facilitated to access the shape and size of the deposit in the area. It is a hill deposit rising 19 M above ground level within the quarry lease area (The highest contour is 235 M). The surface of sheet rock is wavy and irregular. 2.1 Method for estimation of reserves Dolomite Deposit: The Dolomite outcrops are predominantly seen in the northeastern corner of the lease area. Towards south western direction and is concealed under a thin shale cover. The Dolomite is grey and buff in color and massive. The shale is purple colored, thinly laminated, flaggy and contains inter beds of Chert. Dolomite is overlain by shale, gritty conglomerate, sandstone BIF and Laterite. The thickness of Dolomite is expected to be 10 m. Laterite Deposit: The Laterite occurs as capping in the central and southern part of the lease area. It contains lithomarge clay and occurs as blanket like deposit with fairly uniform thickness of about 10m beneath a thin veneer of laterite soil cover. The laterite is steel grey, reddish brown & yellowish brown in color, hard compact and massive. The structure is pisolitic and is porous with cavities. The Top 1.5 to 2.0 m thick laterite occurs as loose, disjointed blocks with fine laterite gravel filling the gap and joints. Below this horizon pinkish and buff colored soft lithomarge clay occurs down to a depth of 8 m as evidenced from the pit dug in the central part of the area by the lessee. The laterite grades into lithomarge clay and both the units are commercially exploitable. 7

13 4 Environmental Management Plan Mining of Laterite involves using heavy machinery and impacts the surrounding environment. In order to reduce the impact, we assessed the possible impacts on surrounding environment and suggested possible preventive measures by categorizing as Air, Noise and Water. The details of the possible causes and measures taken to reduce them are as follows. In addition to these measures a green belt will also be developed to remedy the biomass loss occurring due to the mining process. 4.1 Air pollution management In the process of mining heavy machinery such as excavators, Tippers,etc are used. These result in air pollution at various stages, which are stated as follows 1. Particulate matter generation from the mining process, 2. Particulate matter generation due to hauling, loading & unloading of mined Laterite & Dolomite 3. NOx & Sox generation form the consumption of fossil fuels in heavy machinery and transportation vehicles Measures taken to reduce pollution During mining: Particulate matter generation during mining is mainly from drilling holes which can be controlled by covering the drill holes with cloth. Transportation: a. To minimize the particulate mixing in air during hauling the vehicles are never overloaded and covered with a tarpal b. The particulate generation from the vehicular movement is suppressed by sprinkling water twice a day and conducting regular road repairs Additionally the proposed green belt would act as sinks for particulate matter. 11

14 4.2 Noise Pollution management The major source of noise pollution is due to i. Drilling, ii. Blasting and iii. Vehicular movements. Regular maintenance of noise generating units (repairing, greasing and minimiza- tion vibrations) will be taken to minimize noise levels. During blasting operations the noise level may increase (short time exposures). Blasting will be carried out during daytime to avoid noise intensity to the sur- rounding people at night time. Personal protective equipment like earplugs and other protective devices will be provided to workers those who are working near by the noise generating sources (drill machine operators). But as with distance away from the mining operations, the noise levels will reduce and the anticipated noise levels falls below the day and night residential standard limits set by CPCB (day Leq 55 and night Leq 45 db(a)). Dense vegetation is planned at the periphery of the lease area to minimize the impact of blasting in the surrounding environment. 4.3 Water Pollution Management The ground water table in this belt is 30 m below from the surface and since the quarry depth will not reach upto this depth in the near future flooding by ground water is not anticipated. However, during rainy months, there is a possibility of wet conditions developing in the working pit. This will be minimized if not altogether eliminated by adopting simple techniques like digging trenches all round to drain off rainwater and preventing surface run off from entering and flooding working pit. The water from the will be pumped by deploying suitable pumps, if and when required, the mine drainage can be effectively managed and the pit kept dry to keep up the production schedule. 4.4 Green belt development The whole area is occupied by scattered sparse vegetation of thorny trees and small bushes. In the quarry lease area no wild animals are witnessed as per the statements 12

15 collected from the local population, since 50 years. There will be loss of biomass due to clearing of existing vegetation, but will be compensated by the given afforestation plan. As the site is near to human settlement other than domestic animals no important wild life is found that need to take special attention. However due to planned development of green belt, the area attracts more avifauna and also gives shelter to other domestic animals.

Ambient air quality survey ii. Noise Level Monitoring Ambient air quality and noise level Monitoring will be carried out at minimum three stations, one station within mine site and two stations nearby residential areas out- side the mine. Parameters like suspended particulate matter, sulphur dioxide, oxides of nitrogen carbon monoxide and lead will be monitored. The frequency of monitoring is preferably once in three months on 24 hour basis. The samples will be collected in accordance with the procedures given by CPCB. 4.6 Mine closure plan: Reclamation The top soil or the waste generated from the mine will be used to refill the pit and since it wont be sufficient to fill the mine. The mining pit will be developed as water logged areas with suitable fencing all along the boundaries. Storage of rain water in the mine it will help to improve the ground water table in the area. As this 14

17 area always experiences acute drought situation, this water body can act as a source of water. The aqua fauna like files, prawns,etc. will be developed in the hydro-reclaimed areas by migrating them from the area having similar type of environment. The pit will be fenced appropriately keeping in view the most important aspect of safety. 4.7 Occupational health and safety Health and safety aspects of the mine will be taken care off as per the World Bank (WB) guidelines on open pit mining. The guidelines provide the detailed informa- tion on the aspects that are required to be taken into account for maintaining proper health and safety issues. The workers continuously exposed to dust will be provided with some protective devices like dust mask to prevent respiratory disorders. The workers continuously exposed to a high noise will be provided with ear muffs/ earplugs. Green belt in and around the mining area will be developed to attenuate noise and dust impact. The blasting carried out in the mine area will be carefully planned and executed under the supervision of a responsible officer, to avoid any accidents. Drinking water supply for the employees will be provided by the project authority. The standard of the drinking water will be per WHO guidelines. Periodical training programme to inform the employees about their task, associated risk, and safe working practices will be undertaken. Training will also include information on accident prevention, proper control and maintenance of equipment and safe material handling practices. A regular monitoring of the Occupational Health and Safety will reduce the chances of accidents in the mine. Records of job related accidents and illness should be maintained. This information will be reviewed and evaluated to improve the effectiveness of Environmental Health and Safety programme. 4.8 Other management aspects Records will be maintained for the analysis of ambient air quality and noise levels. These records are not only required for the perusal of the Pollution Control Board authorities. The management will maintain the records as per the hazardous waste regulations and EPA regulations and apply for the annual consents for air and water, and renewal of 15

18 authorization for the storage of hazardous waste as per the Hazardous Waste (Handling & Management) Rules, The records of hazardous waste manifest will be maintained. The format of the same is enclosed in appendix. The mine shall obtain the consent for operation (CFO) as required under section 25/26 of the Water act, 1974 and under section 21/22 of Air Act, 1981, before trial production and commissioning from the State Pollution Control Board. The CFO will be renewed each year by the management. The mine will submit environmental statement every year before September 30. The management ensures that it will comply with all the directions and regulations issued by the Ministry of Environment and Forests, New Delhi, State and Centre Pollution Control Boards. The Consent for Establishment & Consent for Operation will be displayed in a conspicuous location for reference to the inspecting authorities of different departments. 16
