The project authorities and their consultant gave a detailed presentation on the salient features of the project and proposed environmental protection measures to be undertaken alongwith the draft Term of References for the preparation of EIA/EMP. All the Asbestos Cement are listed at S.N. 4(c) under Category ?A? and appraised at the Central level.
M/s Ramco Industries Ltd. have proposed for the Asbestos Fiber Cement Sheet Plant (1,20,000 TPA) at Industrial Area, Plot No. A1, Village Tehsil Bihiya, District Bhojpur, Bihar. Total project area is 20 acres (8,71,200 ft2) and land is allotted by BIADA on lease for 90 years. Gangi Nadi (2 km), Bhitauli Nadi 2 km) Chhar Nadi (3.5 km), Dehra Nadi (3.5 km) and Dehra Nadi (8 km) Bhagan Nadi (10.5 km) and Ganga river (14 km) are located with 15 km radius. PAs have submitted a copy of certificate issued by the Dy. Secretary (industries), Bihar Govt. regarding possession of land. During presentation, PAs have submitted a copy of certificate issued by the Executive Director (Industries), Govt. of Bihar vide letter no. 3168/D/135/DO/ BIADA/09 dated 10th May, 2010 indicating location of the project in notified industrial area Bihiya. No reserve forests is located within 10 Km. Total cost of the project is Rs. 30.00 Crores. Rs. 50.00 Lakhs and Rs. 10.00 Lakhs are earmarked for capital cost and recurring cost towards pollution control measures. No litigation /court case is pending against the proposal.
Asbestos fibres (850 MTPA), Cement (4.550 TPM), fly ash (2,650 TPM) and other additives (pulp, 50 TPM) will be used as raw materials which will be stored in separate location opened in closed chamber and processed in wet condition.
Fibre bags will be fed into closed bag opening device where bags will be opened. Empty bags will be shredded and mixed with fibre. Then fibre will be mixed with 30% water to avoid fibre dust generation. These milled fibres will be stored in the wet form and further opened for hydro-disintegration in a turbo mixer. Wet fibre will be mixed with cement / fly ash to make an uniform slurry and fed to vat machine and converted into Hot A.C. sheets. The felt mill pass over the sieve cylinder and accumulator drum to form sheets of required thickness and transferred to steel template for requisite corrugations profile. The sheets are then cured.
No gaseous emissions will be generated from the production process since the entire process will be carried out in wet condition. Stack emission from D.G. set will be released into atmosphere through gas stack. Dust emissions from the fibre circuit, cement and fly ash circuit and pulveriser will be controlled by jet pulse filter dust collector. Fugitive dust will be notified by regular sprinkling of water.
Total ground water requirement from bore wells will be 80 m3/day and permission for the drawl of ground water from SGWB, Bihar is obtained vide letter dated 22nd February, 2010. PAs have submitted a copy of permission for ground water drawl accorded by Directorate of Under ground water resources issued vide letter dated 22nd February, 2010. The entire treated effluent after settling will be reused/recycled in the process or for dust suppression and green belt development. Sewage effluent will be treated in septic tank followed by soak pit. Municipal solid waste will be used within the plant as manure for plantation. No effluent will be discharged outside the premises and ?Zero? discharge will be adopted.
Solid waste (6.0 TPM) from the fibre cement sheet plant including rejected, cracked, broken sheets will be pulverized, bagged and then taken back to the mixer for use in the process. Dust from the bag filter will also be taken to mixer for reuse. Waste oil and used batteries will be sold to authorized recyclers / re-processors.
PAs have informed that green belt will be developed in 7 acres (35 %) increased to 8.0 acres of the total land 20 acres. Acoustic enclosures will be provided to D.G. Sets. Power (750 KVA) will be sourced from SEB. Fuel (50 l/hr) will be used in DG sets. One D.G. set (750 KVA) will also be installed.
