7 RAW MATERIALS The raw materials required are Asbestos fibre & other fibres (8 to 9%), Binders cement & flyash materials (45 to 47% and 27% respectively) RAW MATERIALS- SOURCE Raw Material Cement Fly ash Fibre Pulp Water Source Nearby sources Nearby Power station Fully Imported from Canada, Brazil,Russia Local Existing Bore wells of VIL LTD As for transportation of goods, there is already existing black topped roads. As for transportation of goods, there is already existing black topped roads from the State High way No 36 to the project site. This is quite adequate for the possible truck movement envisaged. MANUFACTURING PROCESS OF A.C. PRODUCT Asbestos Fiber of different grades are imported, mainly from Canada, Russia, Zimbabwe etc, and received in pressure packed condition in impermeable bags in palletized form. The fibre pallets are transported to the factory in closed containers through the trailer trucks. These palletized fiber bags are unloaded in fiber go-downs with the help of fork lifts. Fiber bag pallets are conveyed to the fiber feeding section by means of fork lifts. The fiber bags shall be slit open in closed automatic bag opening device. The empty bags shall be lifted by a hooking device attached within the bag opening device and carried to the attached bag shredder unit and the fiber after passing through the lump breaker shall be collected in the attached blender where some water shall be added to maintain the process in wet condition.. When all the bags in one charge empties the fiber 7

8 on to the blender, the fiber in wet form shall be taken to the Edge Runner Mill via a screw conveyor and elevator which is also joined by the shredded bag pieces from the shredder unit. Here at ERM some more water is further added to the fibre for milling operation. The bag opening device & the edge runner mill shall be kept under negative pressure by tapping it on to a Bag Filter Type Dust Collector with pulse jet which again is connected to a Hydro-static Precipitator, connected to a blower (capacity _ 7500 m3/hr) driven by a 15 Hp motor. The delivery point of the blower is connected to the Air Wet Washer and through to a 18 m tall stack. The Hydro-static Precipitator works on the principle of tidal wave generation. Particles collected in hydro-static precipitator shall be periodically recycled in wet form. From this point onwards the total process operations involving fibre are carried out in wet condition with no possibility of dust generation during manufacturing process. The milled fiber is weighed in weigh hopper. The pre-requisite quantity of fiber which is about 8% of the product is mixed with required quantity of water in Wet Opener or fibre cone where it is recirculated for about 3 to 4 minutes. The above slurry along with other fibers, if any, a small quantity (around less than 1%) of pulp and small quantities of homogenized solid waste + process sludge in slurry form (from sludge recycling tank/wet Ball Mill) is taken to Beater tank. Cement is received and stored in godown., from where it is conveyed to the Cement + Fly ash Mixing Tank via screw conveyor. Next, Fly ash is received and stored in closed go-down. Fly ash shall be pneumatically conveyed Pre-requisite quantity of Special binders - Fly ash (around 26 to 28 % of the product) is mixed with water, converted into slurry and sent to Storage tanks. A measured quantity of Fly ash slurry is taken to the Batch Hopper and then to the Cement + Fly ash Mixing Tank. The cement + FA slurry thus prepared in the Mixing tank is sent to Wet Rotary Sieve & thence to the Beater Tank, thus joining fiber slurry. The RM slurry thus prepared is transferred to Storage Tank where it is under constant agitation. From here slurry is taken to the Dilution Tank(or Distribution Tank) and diluted further using recycled process water. Slurry from the Dilution 8

9 Tank is taken to the sheet forming machine consisting of an assembly of 5 vats placed in series and with rotating sieve cylinders placed one in each of 5 vats. The sieve cylinders are fitted at its periphery, with the wire mesh of specific size (mostly 40 mesh on top surface and 5 mesh on bottom surface). An end-less felt made of synthetic woven fabric runs tangentially atop the sieve cylinders. The slurry through the sieve cylinders gets filtered out. The differential hydrostatic pressure thus created between the sieve cylinder and Vat causes an asbestos cement film to be formed and picked up by the sieve cylinder which in turn gets transferred to the moving felt. The gradually thickening slurry due to filtration is constantly diluted in the vats. The excess water in film is dehydrated by vacuum system. The wet film from the felt is then transferred on to the rotating sheet forming drum. After the required thickness is achieved the wet sheet is cut by automatic cutter fixed on the sheet forming drum. The formed sheet is then trimmed widthwise with long cutters to the required width. The length of the sheet varies as per the market requirement from 1.5 M to 3 M. after cutting to the required length the sheet is transferred on to the profiling machine (Corrugator) by vacuum sucking. The formed sheets are stacked in between the steel moulds ( templates) which will be air cured for about 12 hrs in a closed chamber. After the air curing the sheets are separated out from the templates in destacker machine. The templates are cleaned and lubricated and sent back to profiling machine. The sheets then are inspected on-line, stacked on steel pallets and water cured for a minimum of 12 days before being finally inspected and then dispatched. 9

We intend to use the best logical tool to assess the impact of the project. The baseline data generated from the above studies will be analyzed and compared with applicable standards prescribed by the CPCB and MOEF. By this means, the impact whether positive or negative will be assessed and the environmental attributes requiring special attention for mitigating the 16

17 negative impact, if any, will be identified. Also the areas, which fulfill the prescribed environmental norms and not requiring further improvements, will be specified. Both short-term and long term impacts particularly on sensitive targets such as habitat of endangered species of wildlife, crops, historically/culturally important sites/monuments, and centers with concentrated population in the study area will be established. Mitigation measures to reduce adverse impacts will be suggested. The potential impacts due to the project could be as follows: Change in land use due to the proposed project Potential impact on soil and groundwater due to waste handling, transportation and disposal Air quality and noise level impacts due to project activities. Potential impacts due to the Vehicular movement and emissions; Storage of materials Impact on socio-economic environment due to increased direct and indirect employment generation, and social welfare activities in the nearby villages The above impact assessment and proposed mitigative measures are described below Impact on Land Use Impact Assessment The land use impacts due to proposed project will be identified in terms of local land use planning efforts. The change in land use pattern of project site will also be identified. This includes visual impact, impact on forest, impact due to industrial growth and growth due to socio-economic factors. 17

18 Mitigation Measures The mitigation measures will be addressed towards restoration of land disturbed by the proposed project activities to the extent possible. Impact on Demography and Socio-Economics Impact Assessment On the basis of the compiled information and the proposed employment and other benefits to the people of the study area as well as others, the likely socio-economic impacts of proposed project in post-project scenarios for demography, facilities and services, agricultural sector, civic infrastructure and basic amenities, industrial sector, economic status and health status of people, etc will be assessed. Mitigation Measures Strategies to mitigate the negative impacts of the project will be developed for areas where negative impacts are projected to occur. The potential actions considered will include both policy and planning actions. The roles of different bodies in mitigation measures will be identified. Impact on Soil Impact Assessment Impacts on soil characteristics include destruction of soil profile, changes in soil productivity, increased erosion and subsequent loss of agricultural soils and land use changes. Details of solid and hazardous wastes likely to be generated from the operations and their treatment and disposal mechanism 18

19 vis-à-vis the proposed treatment facilities in the project will be assessed and mitigation measures will be suggested accordingly. Mitigation Measures Based on analysis, mitigation measures will be proposed which will avoid, minimize or compensate for significant adverse impact on soil characteristics. Impact on Water Quality We propose to address the impacts due to water requirement, Impacts due to the domestic sewage, treatment and disposal will also be addressed. Mitigation Measures Considering the dependence of the people in the area on ground water as sources for drinking purposes, the prevailing quality and extent of contamination due to the proposed project activities, the mitigation measures will include and the treatment required for meeting the effluent discharge standards specified under the Environment Protection Rules and PCB will be addressed. The disposal arrangements will be conceptually indicated. Impact on Meteorology Impact Assessment The climatologically factors, which play an important role in the environmental analysis of the process of transportation, dilution and dispersion of pollutants, will be analyzed. Meteorological data will be collected to ascertain wind roses, atmospheric stability conditions and prevalence of inversion levels around the project site. This will enable to 19

20 define the atmospheric conditions likely to prevail in the study area and use it as a basis for air quality modeling studies. Impact on Ambient air Quality Impact Assessment Emission inventory will be carried in the study area. A computer based internationally recognized mathematical air quality model (ISCST3) suitable for the region would be used to predict the concentration of SO2, NOx & SPM due to the operation of the proposed plant. The results will be presented for short-term (24-hourly) concentrations in and around the project site. The dispersion model results will be included in the report using isopleths or other graphical methods, over laying a land use map of the surrounding area. The predicted air quality results will be compared with existing regulations. Mitigation Measures Potential mitigation measures include the control measures at the source level and providing adequate stack heights. The measures to control the fugitive dust emissions such green belt development and sprinkling will be suggested. Impact on Noise Impact Assessment Sources of noise and its impact on the environment will be addressed. The noise level at varying distances for multi-sources will be predicted using Noise model. A comparison of measured noise (Leq) at monitoring locations 20

21 to that of predicted noise levels (Leq) will be made and mitigatory measures will be recommended to conform to regulatory ambient air noise standards. Baseline noise levels in different zones like industrial, residential and sensitive areas like hospitals, wild life habitation etc will be monitored. The potential noise level exposure will be determined and evaluate for acceptable limits of exposure. Mitigation Measures The potential mitigation measures will be addressed to reduce noise levels by control at source, provision of greenery to absorb noise during its propagation, isolation of high noise generating sources, use of protective measures especially in high noise areas. Impact on Ecology Impacts on terrestrial species especially during dry season will be assessed particularly those which are sensitive to the pollution. Recommendations will be made to mitigate such adverse impacts as soil erosion and habitat loss. 9.0 ENVIRONMENT MANAGEMENT PLAN The Environment Management Plan (EMP) includes all the mitigatory measures proposed under each significant environmental attribute. For each potential negative impact identified, recommendations will be presented for 21

22 avoidance, minimization or mitigation of impacts along with costs associated with potential mitigation. Further, a suitable green belt development plan for the project site will be included in the EMP report. The EMP will addresses the following: Identify and summarize all anticipated significant adverse environmental impacts: Identify and summarize all mitigation measures, including the type of impact to which it relates and the conditions under which it is required; Define a set of policies and objectives for environmental performance and continual enhancement of performance; Wastewater and produced water handling, treatment and disposal; Solid and hazardous waste handling and disposal; Green belt development plan; Recommend monitoring and reporting procedures including the parameters to monitored, methods to be used, sampling locations, frequency of measurements, detection limits and definition of thresholds that will signal the need for corrective actions; Recommend capacity development and training requirements for implementation of EMP; and Recommend an organizational structure for effective implementation of the EMP; An environmental monitoring and management plan have developed for the sensitive elements of the environment that may require monitoring during construction and production phase of the proposed project. Recommendations have made on the institutional arrangements that will be necessary to ensure effective monitoring and management. A detailed management and monitoring program has developed to reduce the effects of potential negative environmental impacts. The EMP also reflects statutory requirements, M/s. VIL LIMITED 22
