Envi-Tech (P) Ltd., Secbad.

15 CPPL firmly believes in the concept of sustainable industrial operations at all their facilities. The proposed project will result in consumption of about 0.20 MTPA of Flyash and MTPA of slag which is otherwise treated as solid waste. CPPL has incorporated all necessary steps to mitigate the environmental pollution in the design stage itself. Environmental Management Plan of the plant details the environmental quality control measures proposed by CPPL during construction and operations phase of the project. 7.1 ENVIRONMENTAL IMPACTS AND MANAGEMENT PLAN - CONSTRUCTION PHASE (i) AIR ENVIRONMENT Setting-up of grinding unit will result in the increase of dust concentrations due to fugitive dust. Frequent water sprinkling in the vicinity of the construction sites would be undertaken and will be continued after the completion of plant construction, as there is scope for heavy truck mobility. It will be ensured that both gasoline and diesel powered vehicles are properly maintained to comply with exhaust emission requirements. The outlet emission is restricted to less than 30 mg/nm 3 for the mill. (ii) NOISE ENVIRONMENT There will be marginal increase in noise levels during construction phase, which is temporary. Noise levels during night time are mainly from welding during the construction phase for short duration. (iii) WATER ENVIRONMENT During construction, the infra-structural services including water supply, sewage, drainage facilities and electrification will be provided to the construction labour. (iv) LAND ENVIRONMENT The project will be located in an area of 3.5 Ha on the land which was earlier put to industrial use the activities of which are now 12 B.S. Envi-Tech (P) Ltd., Secbad.

16 abandoned. The existing infrastructure will be removed and this new Cement Grinding would be setup in the same location. Greenbelt in an area of 1.2 Ha will be developed inside the plant boundary as per statutory norms. (v) SOCIO-ECONOMIC ENVIRONMENT Local people will be given preference through both direct and indirect employment. (vi) SAFETY AND HEALTH DURING CONSTRUCTION PHASE Adequate space will be provided for construction of temporary sheds for construction workers mobilized by the contractors. CPPL will supply potable water for the construction workers. The safety department will supervise the safe working of the contractor and their employees. Work spots will be maintained clean, provided with optimum lighting and enough ventilation to eliminate dust/fumes. 7.2 ENVIRONMENTAL IMPACTS AND MANAGEMENT PLAN DURING OPERATIONAL PHASE AIR ENVIRONMENT The major sources of emissions from the grinding unit are: Clinker grinding process i.e. VRM Packing plant CONTROL MEASURES PROPOSED ARE: Installation of bag filter systems along ventilation systems to control the fugitive dust generated from the material handling areas. All the flue gas outlets will be provided with state of art air pollution control equipment to maintain the particulate emission level below 30 mg/nm 3 The grinding mill and packer house will be provided with Bag Filters designed for an outlet emission of less than 30 mg/nm 3 13 B.S. Envi-Tech (P) Ltd., Secbad.

17 The dust collected in the pollution control devices is recycled back to the process. The roads in the plant will be paved to prevent dust emissions. To control the dust emissions from dropping/transfer points of the belt and bucket conveyors, unit bag filters will be provided at various locations of the transfer points. All the raw material i.e. flyash, gypsum, slag and clinker will be stored in the silos provided with bag filters for control of fugitive dust emissions. Cement storage silos will be provided Bag filters. Apart from above, CPPL proposes to implement the following additional measures for control of fugitive dust: Development of greenbelt all around the plant boundary. FUGITIVE DUST CONTROL For control of fugitive dust, water spray arrangement will be provided to spray water all-round the fuel stock piles to suppress the dust and to wet the coal while compacting to minimize the dust nuisance. Adequate ventilation and dust suppression systems will be implemented in the coal conveyer system. Installation and operation of water spray nozzles at wagon tippler hopper to reduce the dust emission during unloading of wagons. Unloading of material will be carried out with great care by avoiding dropping of material from height, wetting the material by sprinkling water while unloading NOISE ENVIRONMENT Cement mills are the major sources of noise pollution. The following are proposed noise control measures Provision of acoustic dampeners in foundations and insulators in the interiors A scientifically designed greenbelt will be developed all around the plant boundary to act as noise attenuator. In addition personnel working near high noise level generating sources will be provided with earmuffs and ear plugs. Acoustically insulated cubicles will be provided to operators working near high noise generation sources. 14 B.S. Envi-Tech (P) Ltd., Secbad.

18 Effective preventive maintenance and vibration measurement of all rotating equipment will help in the improvement of plant life and also reduce noise. Noise level at the plant boundary is expected to be less than 55 db(a) without considering any attenuation factors WATER ENVIRONMENT No wastewater generation is envisaged from the grinding unit. Wastewater generation is only from domestic use i.e. about 1.8 m 3 /day and the same is treated in septic tanks followed by soak pits LAND ENVIRONMENT The site is free from habitation and hence no displacement of people is envisaged. Therefore the overall impact on land environment will be minimum SOLID WASTE GENERATION Dust collected from air pollution control equipment is 100% recycled in process and no solid waste is generated from cement grinding unit. The waste oil generated from the machines will be stored in barrels. About one barrel per year of waste oil will be generated from the plant. This oil will be disposed to authorised vendors HAZARDOUS WASTE MANAGEMENT RULES CPPL will store the hazardous waste in a designated area. This area will be isolated from the other utility areas. Spent Oil from the gear boxes and automobile batteries will be disposed to the authorized vendors as per the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, TRANSPORTATION The total raw material (except flyash) and finished product will be transported by rail. 15 B.S. Envi-Tech (P) Ltd., Secbad.

19 7.2.8 GREEN BELT DEVELOPMENT The plan for attenuation of the noise and air pollutant levels include design of plantations around the plant boundary, roadside, office buildings and stretches of open land. The vegetation for the attenuation of air pollution would be most needed in the areas where ground level concentrations of the pollutant are high. Of the total plant area of 3.50 Ha, 1.20 Ha. of the plant area will be covered under green belt. A curtain of trees all around the plant will be developed. The species that have history of good survival and growth under similar site conditions will be planted SOCIO ECONOMIC ENVIRONMENT Socio Economic Status in the study area is found to be moderate with respect to livelihood, amenities etc. Transport and other infrastructural facilities such as market centers, business establishment, recreation etc. in the area will be improved. A total of about 24 persons directly and 72 persons indirectly will be employed for this project. The management of CPPL has proposed to give preference to local people for recruitment in semiskilled and unskilled categories. All infrastructure facilities such as education, health facilities and other social facilities are adequate at nearby commercial area i.e., Gairah and Kharsia. CPPL will prepare a well-defined Corporate Social Responsibility (CSR) policy to Carryout social development and welfare measures in the surrounding villages. Under CSR activity CPPL will initiate community development projects, in the fields of health, education and environmental preservation, in and around the plant. 16 B.S. Envi-Tech (P) Ltd., Secbad.

20 OCCUPATIONAL SAFETY & HEALTH MANAGEMENT CPPL will provide all necessary provisions under Factory Act. In addition a Safety committee will be formed and manned by equal participants from Management and Workers. Safety shoes, helmet & uniform will be issued to each worker. Other safety equipment s will be used according to the nature of job involved. CPPL will establish a first aid center with necessary medicines. 8.0 BUDGET FOR EMP CPPL proposes to incur about Rs Crores for implementing the Environmental Management Plan.
