13 2.0 PROJECT DETAILS 2.1 Summary of Project Proposal HIL is seeking an amendment in EC for incremental increase in Production Capacity of Aluminium Smelter from 359 to 371 KTPA Through Process Optimization, HIL plans to increase the Current Amperage from the existing level of 360 ka to 372 ka. This will be achieved with the existing systems in the Smelter Plant. No installation of additional Pots or Equipment. HIL shall be doing necessary Thermal Balance by adjustment of relevant Smelter Pot Room Parameters. Minor improvements will be done in Cast House and Carbon Plants to facilitate this amperage increase. No lining and Busbar changes are required to meet this enhanced amperage. Enhancement of input amperage will result into marginal increase (3.6 %), to the tune of 12 KTPA, in Aluminium Production Level. Increase in current will lead to increased heat input Will be compensated by: Increased target metal height Reduced cover height Lower target resistance (Low AMD) Increase in current will lead to lower butt height Will be compensated by combination of following: Increased anode height Increased anode density Reduced anode change cycle time Controls through Alpsys Increase metal quantity will be tapped using modified metal tapping table. Feeding will be modified by adjusting feeding parameters Work organization for following major activities will be adjusted as per requirement: Anode change Metal Tapping Beam Raising Measurements and Bath transfer. Rev. 01, Final 14/20

14 Others Tapping of increased metal will be managed through existing ladles through increased ladle cleaning frequency. Increased PTA engagement will be managed by reducing breakdowns, reducing anode change and tapping time by enhancing skills through training. Metal and anode transfer will be managed by reducing breakdowns and enhancing operator skills through training. Increased metal quantity will be managed in cast house using existing set up, enhanced skill of operators through training and minor improvement jobs. Rev. 01, Final 15/20

15 3.0 IMPACTS DURING OPERATION PHASE 3.1 PREAMBLE The report presents impacts due to incremental increase in Production Level of Smelter (359 to 371 KTPA) Since the project is already under operation and there has not been any change in the project facilities, the changes in impacts during construction phase will not be there and have not been discussed. The impacts and mitigation w.r.t. the same have been discussed in the report. 3.2 PROPOSED PRODUCTION ENHANCEMENT Following raw materials and other requirements have been envisaged for the proposed production enhancement: Alumina - HIL will require MT of additional alumina to meet this enhanced volume. This will be sourced from HIL s Captive Alumina Plants and import, if required based on Business decision. Power - Existing installed capacity of 900 MW (5 x 150 MW Units in Operation and 1 x 150 MW Unit as Standby) will be sufficient. Water - No additional requirement. Water consumption will be within the approved limit of 4600 m3/h. Coal - Power Generation will remain within 750 MW and the coal consumption will remain within approved limit of 3.5 MTPA. Aluminium Fluoride Plant s Fluoride Consumption will remain within approved limit of 10 kg/mt of Aluminium (CREP Guidelines) Land - No additional requirement; No Forest Land is involved. Capital Investment - No additional Capital Investment is needed to meet this enhanced production capacity. Manpower - No additional Manpower requirement Addition of New Equipment - None Change in Product Portfolio - None. The Product will be Aluminium Ingot, SOWS, Billet and Wire Rod. Rev. 01, Final 16/20

16 3.2.1 Pollution Load Increase ETP Since there is no additional requirement of water for this enhanced production capacity, no change in Water Pollution Load. Current ETP capacity: 300 m3/h. Fluoride Level Since the increase in production capacity is very marginal (3.6 %), with the existing Gas Treatment Centre, HIL will be able to maintain the Fluoride Emission within approved limit of 0.67 kg/mt, mentioned in the EC. PAH Level No change. Will remain with the approved limit within the Existing Fume Treatment Centre. Spent Pot Lining No additional generation as there is no increase in number of Pots. Hence, from the above points, it is clear that HIL can achieve proposed additional production capacity without any negative impact to environmental systems. Rev. 01, Final 17/20

17 4.0 ENVIRONMENT MANAGEMENT PLAN 4.2 Ambient Air Quality Various efforts have been taken to reduce particulate matter levels in ambient air as summarized below: Proper upkeep and maintenance of vehicle, water sprinkling, sweeping on roads and construction site doing regularly for dust Suppression. Internal roads completed. GTC & FTC (Gas treatment center and Fume treatment plant) is in operation to control emission from pot room and baking furnace respectively. Stacks have been constructed with adequate height for wider dispersion of gaseous emissions. Online Continuous monitoring system has been provided for Stacks. Closed conveying system for alumina handling, completed. Bag filters provided at all transfer points to control fugitive emission. Regular water sprinkling done at site to minimize fugitive emission due to vehicle movement. Developing of green belt in and around the plant and colony is in progress. HIL has planted about 4,43,000 plants till date covering land of area 189 ha and Target to cover 33% of total land. Particulate fluoride emissions well within the limit of 0.67 kg/tonne of aluminium produced. Online continuous stack monitoring equipment installed at Gas treatment Centre (GTC) stacks of Pot room for measuring particulates and fluoride emissions. Dedusting systems are in operation at carbon plant. Water sprinklers installed in raw material (coal) handling area. Housekeeping already in place at plant premises. Suitable dust suppression system provided to control fugitive emission during material handling. HIL has already invested more than Rs. 850 Crores for pollution control and appropriate recurring cost has been earmarked for smooth running of the facilities. Control equipment is installed to restrict particulate emission below 50 mg/nm Greenbelt Details Photographs depicting greenbelt development at site are given in Figure-5. HIL has taken initiative to develop green belt right from the beginning of project stage in form of in-situ plantation under sustainable development policy. Till date HIL has Rev. 01, Final 18/20

18 planted more than 4.43 Lacs nos of tree sapling in different location of CPP smelter and township covering about 189 ha area, which are now in well growth with good canopy. HIL has taken a drive to increase the greenery in the premises by in situ method by direct sowing of seed at site of local species mainly Ziziphus mauritiana, Butia monosperma, mangifera indica, Acasia nilotica and acasia catechu etc since early project stage. Which has now become big tree with good canopy and compensating the environment loss. The nos of plants through in situ plantation are more than one lacks in 40 Ha. Rev. 01, Final 19/20

20 5.0 CONCLUSION The plant has already obtained EC and is already fully equipped with effective pollution control measure and environmental management action plan. Through Process Optimization, HIL plans to increase the Current Amperage from the existing level of 360 ka to 372 ka with the existing systems in the Smelter Plant. No installation of additional Pots or Equipment has been proposed. Necessary Thermal Balance by adjustment of relevant Smelter Pot Room Parameters will be done. Minor improvements will be done in Cast House and Carbon Plants to facilitate this amperage increase. In view of the need based analysis of the project, the proposed process optimization is most required with no incremental in pollution load and is beneficial. HIL would be grateful for grant of Amendment of Existing Environmental Clearance for proposed enhancement of Aluminium Smelter Capacity from the current level of 359 KTPA to 371 KTPA through Process Optimization without any adverse impact on Environment. Plant s installed Captive Coal Based Power Plant capacity will remain at 900MW (5 x 150 MW in Operation and 1 x 150 MW as Standby). HIL requests for exemption from EIA and Public Hearing and to grant EC amendment based on the submitted detailed environmental impact analysis and EMP report. Rev. 01, Final 21/20
