31 IMPACT ASSESSMENT AND MITIGATION MEASURES

32 IMPACT ON LAND USE AND SOIL QUALITY

• Enhancement in production capacity of BF-1, BF-2 & BF-3 will be mainly achieved through process optimization, efficiency improvement and technology upgradation, hence there will be no major construction activity except as mentioned in the earlier slides.

• The proposed oxygen plant, DI pipe, Fe-Si plant, addition of 4 ovens in Battery-1 will be located within the existing pig iron plant premises at Amona/Navelim village and includes activities related to leveling of site, construction and erection of main plant structures and installation of equipment.

• The existing pig iron plant at Amona/ Navelim village is established in an area of 161 ha, out of which 20.21 ha is required for the proposed additional units.

• No change in land use is envisaged as the proposed expansion will be within the existing plant premises.

33 IMPACT ASSESSMENT AND MANAGEMENT-AIR QUALITY

• Major Unit Wise Emissions and Mitigation Measures

 Raw Material Handling Area:

The material handling area which generates high fugitive emissions include:

• Unloading areas of trucks; • Stock piles and storage areas; • Crusher and screening area; • Transfer through conveyor belts; and • Vehicular movement.

Mitigation Measures

• The dust generated during coke, coal handling, crushing and screening is captured by suction hoods and then collected in the bag filters.

• The coal/coke fines is recycled for coke making or/and making sinter;

• Local exhaust ventilation is provided for coal crusher house and screening towers, etc; 34 IMPACT ASSESSMENT AND MANAGEMENT-AIR QUALITY

• Coal is stored in the covered coal shed;

• Water spray nozzles are being provided over dust generation points.

• Dry Fog Dust Suppression (DFDS) are adopted for dust suppression;

• Bag filters are provided for coal crusher house, coke screening towers, transfer points, raw material handling sections, etc.

• Also rain gun sprinklers are provided at raw material yard. Coal is stored in the closed shed.

• Wind screens are installed along the raw material storage yard.

• Bag house de-dusting system is provided for proportioning bin, sinter screening building, flux and fuel crushing and small dedusting units for various transfer stations.

35 IMPACT ASSESSMENT AND MANAGEMENT-AIR QUALITY

 Coke Ovens

• The coke oven plant is based on non-recovery technology.

• Ovens are under negative pressure and all volatile matter is combusted in-situ from which power is generated.

• Modified wet quenching of coke is adopted.

• Coke Oven Flue Gas (COFG) is fully utilized in Waste Heat Recovery Boilers (WHRB) for clean power generation.

• Bag houses are provided for screening towers in coke oven plant, and all the transfer points are provided with dust extraction system or dry fog system to ensure the control of emissions during screening.

 Ferro Silicon Plant

• The gaseous matter and fumes generated in the furnace is treated through pollution control equipment and clean gas is allowed to escape to the atmosphere through chimney.

36 IMPACT ASSESSMENT AND MANAGEMENT-AIR QUALITY  Blast Furnace (BF)

• Main emissions from the BF :- Iron oxide particulates and graphite: Controlled by local hooding within the cast house and emissions are directed to a fabric filter

• Hot BF gases: These gases exit at the top of the blast furnace and proceed through gas cleaning equipment where particulate matter is removed from the gas and the gas is cooled.

• This gas has a considerable energy value so it is burned as a fuel in the "hot blast stoves" which is used to preheat the air entering the blast furnace to improve the efficiency and reduce the fuel rate.

• The remaining gas is sent to the boiler house for generation of clean electrical energy through existing WHRB.

• The BF stock house are provided with DE systems complete with dust extraction hoods, ESP, ID fan and stack of adequate height.
