San Envirotech Pvt. Ltd., Ahmedabadin association with Team Labs & Consultants, HyderabadExecutive SummaryE-1 BACKGROUNDSince India is a developing country and industries have always playedmajor role in the economic development of the country. Gujarat is aone of the well developed industrialized state and has a significantcontribution in industrial as well as economic development of thecountry.M/s. Vinayak TMT Bars Pvt. Ltd. is the existing unit located at SurveyNo. 25/1, 25/2 & 24p, Bayad Road, Village: Barot na Mosampur, Post:Sampa, Dahegam, Dist.: Gandhinagar, Gujarat. From theestablishment, the unit has been engaged in manufacturing of TMTbars with 2450 TPM production capacity. Now, the unit proposes toexpand its production capacity up to 12000 TPM. Thus, additional 9550TPM of TMT bars will be manufactured. The unit also intends to installmelting furnace of 20 TPH (10x2) capacity to satisfy industrial heatrequirement. The proposed expansion will be in the same premises &due to proposed expansion there will be addition of some newmachineries and related civil structures.The total area of the premises is 46474 m 2 , out of which 32531 m 2(Approx) areas has been already utilized for existing unit. Theproposed expansion will be in the same premises. There will not beany additional land requirement for the proposed expansion.E-2 PROJECT DESCRIPTIONLocation of ProjectVinayak TMT Bars Pvt. Ltd. is the existing unit located at Survey No.25/1, 25/2 & 24p, Bayad Road, Village: Barot na Mosampur, Post:Sampa, Dahegam, Dist.: Gandhinagar, Gujarat. Proposed expansionwill be carried out in the existing premises.The location of the project site is given here under in terms oflongitude and latitude.EIA report of M/s. Vinayak TMT bars Pvt. Ltd.

Latitude: 22 0 11’’04” NLongitude: 72 0 52’55’’ ESan Envirotech Pvt. Ltd., Ahmedabadin association with Team Labs & Consultants, HyderabadElevation from sea level is 78.94 meter (from Mean Sea level).Site SelectionUnit has been already in existence since long and is familiar with thesurrounding environment; therefore, it becomes easy for the unit toexpand the project in the same premises. In addition, there will not beany industrial effluent generation from the proposed project activities.Thus, it will become easier for the management to expand the project.The selection of the project site at this location was considered on theavailability of the following amenities:• The nearest town Dehgam and city Ahmedabad are 6 km and 25km away from the project site, which is very well connected withother parts of the country by road & rail.• Availability of all basic facilities like fuel, water, power, man power,raw materials, etc.• Good communication and transportation facilities• No R & R will be required• No national parks or wildlife habitats fall within 10 km radius oflocation.Alternative LocationsSuitability of transportation facilities; and availability of existinginfrastructure such as power, roads, telecommunications, water at theexisting project, the unit has decided to develop proposed expansionat the same premises. Therefore there is no need of alternativelocations.E-3 PROPOSED PRODUCTION CAPACITIES OF PLANTVinayak envisages increasing the production capacity of TMT bars from2450 TPM to 12000 TPM with installation of melting furnace of 20 TPH(10x2) capacities.Production detail is given hereunder:EIA report of M/s.

Based on the data,the relevant impacts on various environmental components were alsopredicted by using appropriate mathematical models as well as impactassessment techniques. An appropriate environmental managementplan was also delineated to minimize the adverse impacts.E-5 AIR ENVIRONMENTThe ambient air quality monitoring was carried out at six AAQMlocations, with a frequency of twice a week, to assess the existingsub-regional air quality status during the month of Jan-11 to March-11. Respirable Dust Sampler along with the analytical methodsprescribed by CPCB was used for carrying out air quality monitoring.At all these sampling locations; PM 10 , SO 2 and NOx were monitored on24-hourly basis to enable the comparison with ambient air qualitystandards prescribed by the Central Pollution Control Board.EIA report of M/s.

Ltd., Ahmedabadin association with Team Labs & Consultants, HyderabadE-8 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURESAir EnvironmentSource of Air PollutionAt present, the main emission source from the plant is flue gasemission from furnace and D.G. set. After expansion, there will beaddition of flue gas stacks as installation of more furnaces and oneD.G. set.At present natural gas is use as fuel for furnace. Same will be usedafter proposed expansion. Therefore, the flue gas emission will bealmost within gaseous emission norms. However, coal will use as analternative fuel only in case of non availability of natural gas, for that,on the precautionary bases unit proposes to install cyclone separatorto achieve the emission standards.There will also installation of D.G. sets within premises which will beused only in case of emergency and HSD is used as fuel.The unit also proposes adequate stack heights of 30.0 m for the eachFurnace and 11.0 m for D.G. sets respectively for proper dispersion ofgaseous emission.The probable emitted pollutants will be SPM, SO2 and NOx. However,it will be almost within the emission norms.Air Quality Modelling and PredictionsIt is predicted that the maximum contribution in GLCs, with unitsoperating at full capacity, is 1.536 μg/m 3 , 0.970 μg/m 3 and 0.194μg/m 3for SPM, NO X and SO 2 respectively are found negligible. Thepoint of maximum concentration by unit would be 3.0 km from centreof industry in N direction.With this marginal contribution due to the proposal of the project, thelevels of SPM, SO 2 and NO X will be below residential area limitprescribed by CPCB.Water EnvironmentThe water requirement will be met by its own bore well. Existing freshwater requirement will be 75 KLD which will be increased up to 250EIA report of M/s. Vinayak TMT bars Pvt. Ltd. E-7

The fresh water will be required fordomestic, cooling and gardening purposes.There will not be any industrial wastewater generation. Only domesticeffluent will be generated which will be disposed to soak pit throughseptic tank.Thus, there will not be any major impact on the water environmentdue to proposed project.Solid Waste ManagementThe entire quantity of hazardous waste will be handled and disposedas per Hazardous Waste (Management, Handling and Trans boundaryMovement) Rules’2008 (amended time to time). The main Solid wastegeneration will be Slag and spent/waste oil.As slag is in inert in nature it will be use or reuse in road making insame premises. While Used Lubricant Oil can be reuse in own premisesor sold to registered recyclers.The unit will provide isolated area for the storage of hazardous waste.Thus, hazardous waste management system provided by the unit willbe adequate and there will not be any major impact on theenvironment due to hazardous waste management.Green Belt DevelopmentAfter Expansion, the total greenbelt will be 15357.32 m 2 , which will be33% of total area.E-9 ENVIRONMENT MONITORING PROGRAMThe details of monitoring are as below:Nature of Analysis Frequency of Analysis Number ofSampleStack Monitoring ofMonthlyAt all stackseach stackAmbient Air Quality Monthly for 24 hours or as 3 locationsMonitoringper the statutory conditionsNoise Pollution Monthly for 24 hours or as 6 to 8 locationsper the statutory conditionsHeath check up of As per the statutoryAll the workersworkersguidelineWork zone Heat stress- once in three 3 to 4 locationsEIA report of M/s.
