MINUTES OF2ND RECONSTITUTED EXPERT APPRAISAL ...

The project authorities and their consultant, M/s Vimta Labs Ltd., Hyderabad gave adetailed presentation on the salient features of the project and proposed environmentalprotection measures to be undertaken as per Terms of Reference (TORs) awardedduring the 32 nd Meeting of the Expert Appraisal Committee (Industry-1) held during27.1.2012 – 28.1.2012 for preparation of EIA/EMP report. Since the proposed projectactivity is an expansion/modification of the existing category ‘A’ project, the proposal isappraised by the Expert Appraisal Committee (Industry) of MoEF.M/s Tamil Nadu Newsprint and Papers Limited have proposed to install a De-Inking Plant (DIP) of 300 TPDand upgrade the Co-Generation Plant (CCP) in theexisting premises of the pulp and paper plant at Kagithapuram, District Karur in TamilNadu.Existing plant area is 375 acres and the total area including township etc. is 778acres. Proposed project requires an area of 6 acres and will be located within theexisting plant premises. The green cover developed by TNPL at its mill site, housingcomplex and surrounding area is about 263.75 acres out of a total area of 778 acres(34%). `There are no ecologically sensitive areas/reserve/protected forests within 10 kmradius study area from the plant. The total project cost is estimated at Rs.310 Crores. Ofthis, pollution control equipment and pollution control measures account for Rs.39Crores.MoEF RO, Bangalore monitored the existing project on 18.7.2012 and 19.7.2012.A copy of the certified compliance report from the RO is submitted. The compliance tothe conditions stipulated in the environmental clearance is satisfactory except thesubmission of action plan for the disposal of Reverse Osmosis rejects and developmentof 33% green belt.The DIP will have the state-of the art line with three loops and two dispergers tomanufacture printing and writing (P&W) grade of deinked pulp (first of its kind in theCountry). The DIP will replace costlier and frequently scarce imported would pulp. Therewill not be any increase in the paper production beyond 400,000 TPA as approved underearlier Environmental Clearance. The Co-Generation Power Plant will be upgraded byinstalling one 125 tph, 105 ata high pressure CFBC multi-fuel boiler with one 41 MWdouble extraction-condensing turbo generator. The power generation will increase from81.12 MW to 103.62 MW as part of this up-gradation. The objective of up-gradation ofco-generation plant is to replace the three aged low pressure boilers with one highpressure Circulating Fluidized Bed Combustion (CFBC) multi-fuel boiler. This alsoinvolves de-rate one aged low pressure turbo-generator and replace two aged lowpressure turbo-generators with one high pressure double extraction-condensing turbogenerator.The CFBC boiler will maximize the use of bio-mass fuels. No additional freshwater will be required. The new 41 MW turbo generator will deploy an air-cooledcondenser, instead of conventional water cooled condenser, which is a waterconservation initiative. There will not be any additional wastewater discharge.Base line data of ambient air quality monitored at 10 locations indicates thatconcentrations of PM 10 , PM 2.5 , SO 2 andNO x are varying from 40.6 µg/m 3 to 72.5 µg/m 3 ,14.7 µg/m 3 to 23.5 µg/m 3 , 10.7 µg/m 3 to 22.4 µg/m 3 and 15.2 µg/m 3 to 28.8 µg/m 3respectively. AAQ modeling study indicates that the maximum incremental GLCs afterthe proposed expansion would be 0.2µg/m 3 , 6.27µg/m 3 and 0.21µg/m 3 with respect toPM, SO 2 and NO x respectively. The resultant concentrations are within the NAAQS.Theexisting water requirement is 53,800 m 3 /day which will be reduced to 52,800 m 3 /day.Post project water requirement will be reduced by 1000 m 3 /day, owing to installation ofair cooled condenser in place of water cooled condenser. The process waterrequirement of DIP will be met by back water from paper machines. The Mill holds
