1 Minutes of the 36th Meeting of the Expert Appraisal Committee ...

M/s Birla Corporation Limited have proposed for capacity enhancement of cement plant from 1.2MTPA cement to 2.0 MTPA clinker (2.7 MTPA of cement) of New Chittor cement works and installationof captive thermal power plant of 80 MW (50 MW+30 MW) within the existing facilities at VillageChanderia, District Chittorgarh in Rajasthan. The proposed expansion will be within the existing plantpremises and no additional land will be required for the proposed expansion project. Existing greenbeltin the plant and colony is 97 ha. National Park, Wildlife Sanctuary and Biosphere Reserve are notlocated within the study area. Degraded reserved forests are located at Chittorgarh at about 5 Km fromthe existing facilities. Chittorgarh Fort, a notified archeological monument, is located at 3.5 Km in theSSE direction of the facility. Total cost of the expansion of New Chittor cement works from 1.2 MTPACement to 2 MTPA clinker (2.7 MTPA Cement) is Rs. 202 Crores and capital cost of the proposedthermal power plant (50 MW+30 MW) is Rs. 310 Crores. Capital cost for environmental protectionmeasures in the New Chittor cement works is Rs. 61 Crores and Recurring Cost is Rs. 0.5Crores/annum. The existing 1.2 MTPA cement plant of New Chittor Cement works was accordedenvironmental clearance vide MoEF letter No. J-11011 / 33 / 95 – IA II (I) Dated 8 th May 2008 and isunder final stages of construction.Details of the existing and proposed products along with their production capacity of New ChittorCement unit are given below:S.

Major raw material required for the proposed expansion of cementplant is limestone, which will be sourced from the captive limestone mine. Other raw materials areGypsum & Fly ash, which are sourced from Rajasthan and Kota Thermal Power Plant respectively. Bothcoal and pet coke will be used in the 2.0 MTPA clinker (2.7 MTPA cement) New Chittor Cement plantand proposed thermal power plant. Total coal requirement in the New Chittor Cement plant afterexpansion is 0.32 MTPA and coal requirement in proposed thermal power plant (50 MW+30 MW) is 0.67MTPA. The actual coal consumption in the facility will be less than the projected values due to utilizationof pet coke. Electrical power requirement in the New Chittor Cement plant after expansion is 45 MW andthe auxiliary power requirement in the proposed thermal power plant of 80 MW is 8 MW.The baseline study was conducted for the project for the summer season, 2010. As per theAmbient Air Quality Monitoring carried out, PM 2.5 & PM 10 ranges between 6 to 29 g/m 3 and 42 to 120g/m 3 , respectively. SO 2 & NO x concentrations were found in the range of 3 to 12.7 g/m 3 and 4 to 29.3g/m 3 , respectively. Max incremental GLC for Sulphur Dioxide and Oxides of Nitrogen for proposedfacilities will be in the order of 33 µg/m 3 and 25 µg/m 3 respectively. The AAQ data at Chittorgarh Fort wasalso monitored. Pollution control equipments like ESP, Bag houses and Bag filters will be installed tomaintain the dust concentration well within the prescribed CPCB Norms. All material transfer points havebeen provided with bag filters to control the particulate emissions at the source itself. Clinker & fly ashwill be stored in silo and gypsum in covered yard.55
