MINUTES OF2ND RECONSTITUTED EXPERT APPRAISAL ...

methodology includes biomass size reduction, pretreatment technology, enzymeshydrolysis, fermentation followed by distillation process & the effluent so produced willbe reused to have zero discharge. Utilities such as boiler, heater and DG set will not beinstalled and sourced from existing unit.Additionally, PAs informed the Committee that ambient air quality monitoring wascarried out at 9 locations during March, 2011 – May 2011 and submitted data indicatesPM 10 (48.8-86.2 ug/m 3 ), SO 2 (18.1-24.2 ug/m 3 ) andNO x (10.2-14.9 ug/m 3 ). Ammoniavapour will be passed through chilled water for ammonia condensation followed byscrubber. The recovered ammonia will be reused into the process. Water requirementfrom ground water source will be 31 m3/day. Effluent generation will be from fermenterwashing and lignin separation, which will be recycling into process. Spent wash will beconcentrated in MEE followed by incinerator. Lignin will be burnt in boiler.Environment Clearance for the existing distillery unit has been accorded by the Ministry’sletter no. J-11011/219/2003-IA-II(I) dated 11 th July, 2006. Committee deliberated uponthe compliance report and the project proponent responded satisfactory.The Committee deliberated upon the issues raised during the Public Hearing /Public Consultation meeting conducted by the UP Pollution Control Board on 2 nd April,2012. The issues raised during public hearing were benefit from projects, treatment ofwastewater, air pollution, raw materials etc and have satisfactorily been responded bythe project proponent and incorporated in the final EIA/EMP report.After detailed deliberations, the Committee found the final EIA/EMP reportadequate and suggested to stipulate following specific conditions alongwith otherenvironmental conditions while considering for accord of environmental clearance:i. Ethanol production shall be based on Lignocellulosic Biomass.ii. As proposed, utilities such as boiler, heater etc shall be sourced from the existingunit.iii. Ammonia vapour will be passed through chilled water for ammonia condensationfollowed by scrubber. The recovered ammonia will be reused into the processiv. Total fresh water requirement from ground water should not exceed 31m3/dayand prior permission for drawl of ground water should be obtained fromthe CGWA/SGWA.v. Spent wash generation from molasses should not exceed 8 Kl/Kl of alcoholrespectively. Spent wash will be concentrated in MEE followed by incineratortoachieve zero discharge. Effluent generation will be from fermenter washing andlignin separation, which will be recycled into process.vi. Spent wash should be stored in impervious lagoon with HDPE lining as perCPCB guidelines and should be kept in proper condition to prevent ground waterpollution. Storage capacity of spent wash lagoon should be for 5 days.vii. As proposed, no effluent from distillery and co-generation power plant should bedischarged outside the premises and Zero discharge should be adopted.
