Addendum EMP for Enhancement of Kamanda Steel Plant from 0.9 to 0.97 MTPA 4

2.0 TOPOGRAPHY AND DRAINAGE

There will be no change in the impact or management of topography andand drainage as given in the EIA submitted for EC dated 06.11.2017 oraddendum EIA submitted for EC dated 08.03.2019. This is because theplant area disturbed due to construction broadly remains the same and thecapacity enhancement is occurring by better utilisation and use of betterquality of raw material in the same units.

3.0 CLIMATE AND METEOROLOGY

There will be no change in the impact of management of climate andmeteorology as given in the EIA submitted for EC dated 06.11.2017 oraddendum EIA submitted for EC dated 08.03.2019. There will be areduction in total coal consumption to the tune 92128 TPA, therefore,reducing the total carbon dioxide emissions into the atmosphere.

4.0 AIR QUALITY

4.1 Impact on air quality

a) Construction phase

The construction and erection of proposed plant and equipment is underwayand will generate dust resulting in higher SPM levels in surrounding area.Further due to deployment of various mechanical equipment and transportvehicle, enhanced SO2 and NO2 levels are expected. Thus, air quality islikely to be effected marginally which may not require any mitigationmeasures of considerable magnitude. Moreover, the impact on the airquality during construction phase will be localized, temporary and reversiblein nature.

Dust emissions from non-residential and commercial construction are afunction of the total area of land disturbed and the duration of activities done.Based on field studies, the AP-42 (Compilation of Air Pollutant EmissionFactors, US EPA, Section 13.2.3) gives the total suspended particulateemission factor estimate as 2.69 megagrams (Mg)/hectare/month ofactivity.

b) Operation phase

Two types of generation and discharge of pollutants, viz., fugitive emissionsand stack emissions, have been considered.

(i) Stack emission of gases from the various units of the PelletisationPlant, Sponge Iron, Blast Furnace, Steel Melting, washery, sinter plant,coke oven plant, ferro alloys plant and Captive Power Plant. Theemission of gases from the additional plants and the associatedfacilities will add pollutants to the atmosphere, which will requiremitigation measures.

Rungta Mines Ltd.

Addendum EMP for Enhancement of Kamanda Steel Plant from 0.9 to 0.97 MTPA 5

(ii) Fugitive emissions comprise mostly of raw material/ product dustgenerated from different material handling operations, e.g., transport,storage, processing, transfer, loading, unloading, etc.

To assess the impact on air quality, the modelling has been carried out inthree steps for:

Step-1: The installed units (DRI, SMS, CPP) as on 30.04.2020 within theplant of 0.277 MTPA, which is already reflected in the monitored ambient airquality

Step-2: The units sanctioned in EC dated 06.11.2017 along with theamendments & enhancement proposed in EC dated 08.03.2019 &19.07.2019 (upto 0.9 MTPA).

Step-3: Since the model is being run with terrain inputs for enhancedcapacity, hence, 0.90 MTPA is also being re-run with same terrain basedreceptors to get the revised output along the same lines of step 1 & 2. Themodel output in the EIA or addendum EIA are not comparable to the modeldue to updation of stack data, commencement of operation of additionalunits as well as incorporation of terrain in model.

The difference between Step -1 and Step-2 will be the incremental impact ofthe pollutant levels on ambient air quality for enhanced capacity (0.97MTPA). The difference between Step-1 and Step-3 will give the incrementalimpact of the pollutant levels on ambient air quality for sanctioned capacity(0.90 MTPA). The difference between the above two calculations will be theincremental GLC due to enhancement with respect to the sanctionedcapacity.

The baseline data is monitored and submitted to MoEF&CC Regional Officeas part of six monthly annual reports. Regular monitoring of ambient airquality is being carried out by M/s. Mitra S.K. private Limited, NABLaccredited Laboratory at 4 locations as given in Table 2 .

(1) The enhancement in the capacity of the LRF from 2X20 T to 3X20 Twill warrant increase in volume of air entering into the bag filter andexiting the stack. The bag filter will be enhanced keeping the stackssame.

(2) The change in configuration of the sinter plant warrants doubling ofstack gas volumes exiting the stacks since instead of two stacks, nowentire volume will exit from one stack. Location of one stack isconsidered same, while the second will not be required due tochange in configuration from 2X24 sq.m. to 1X48 sq.m. The pollutioncontrol equipment will be enhanced commensurate to stack volume.

(3) The change in configuration of the blast furnace warrants that thestack gas volumes exiting the stacks change commensurate to therevised configuration from 2X262 + 1X260 cum to 1X350 + 1X434cum. The total exit volume from both stacks remains same. Thepollution control equipment will be enhanced commensurate to stackvolume.

(4) The annual pollution load into the atmosphere from the unitsundergoing enhancement will change as follows:

DRI plant- production increase is by 6.35% but the total coalconsumption increases by 5.61%. Therefore, the total sulphurdioxide emission due to 0.5% sulphur content in this 5.61% extracoal will increase by about 0.028%, after about 80% absorptionby limestone. The particulate matter emission will be as per thelimits specified in the CTO.

SMS- production increase is by 7.7%. There will be increase inflow volume but the particulate matter emission will be as per thelimits specified in the CTO. The pollution control equipment willbe enhanced commensurate to stack volume.

Rolling Mill - production increase is by 7.7% and the furnace oilconsumption in reheating furnace will also increasecorrespondingly only if 100% of the time the reheating has to becarried out. However, reheating will be operated for about 20% ofthe time only due to hot charging. In previous EIAs & AddendumEIA 100% reheating furnace operation has been consideredwhile for this EIA addendum only 20% operation will beconsidered. Thus, the total pollutant emission in a year willactually decrease by nearly 78% compared to previous estimates.The particulate matter emission will be as per the limits specifiedin the CTO.

Pellet Plant - production increase is by 20.3% andcorresponding to that the total coal and coke breeze consumptionis decreasing by 68%. The furnace oil specific consumption willreduce from 18 liter/T to 17 liter/T but total consumption will riseby 13.7%. Therefore, the total sulphur dioxide emission into thearea will decrease due to coal, coke breeze but increase due tofurnace oil in the vicinity. The particulate matter emission will beas per the limits specified in the CTO.

The gases coming out from the kilns/WHRB/AFBC/Sinter plant/FA plant/Coke oven contain pollutants like particulate matter, SO2 and NO2. This gasstream is a major source of air pollution, if control/ mitigation measures arenot incorporated. To control air pollution, CO is destroyed by combustion inthe After Burning Chamber in DRI. Major portion of the particulate matter inthe gas stream will be separated in the Dust Settling Chamber and theElectrostatic Precipitator.

Rungta Mines Ltd.

Addendum EMP for Enhancement of Kamanda Steel Plant from 0.9 to 0.97 MTPA 12

The use of dolomite, limestone as additive in the kilns reduces SO2

emissions significantly. Controlled combustion air supply to the kilns,controlled combustion temperature and use of low NOx burners controlsNO2 formation. The gas stream, exiting from the ESP, contains particulatematter in concentrations below 50 mg/m3.

All sources of fugitive dust emission have been provided with dust collectionsystem, where the dust-laden air is drawn, passed through bag filters anddischarged into atmosphere through 15-110 m high stacks.

Simulation model for prediction of ground level concentrations due tostack emissions

In order to predict the impact of the project, air quality prediction modellinghas been carried out using US EPA’s ISCST3 model. ISC3 short term mode(ISCST3) is a steady-state Gaussian plume model which can be used toassess pollutant concentrations from a wide variety of sources associatedwith an industrial complex. This model can account for the following: settlingand dry deposition of particles; downwash; point, area, line, and volumesources; plume rise as a function of downwind distance; separation of pointsources; and limited terrain adjustment.

The following options were considered while modeling to predict theincremental ground level concentrations of pollutants due to emissions fromthe proposed units.

• The GLCs due to emissions from the existing units are assumed to bereflected in the ambient air quality monitoring.

• The stack and emission details for Existing and Proposed units havebeen adopted from Table 3 and Table 4.

• The prediction has been done to estimate concentration value over aradial distance of 10 km from the source.

• Combination of Cartesian and polar receptor network has beenconsidered.

• Emission rate was considered constant throughout the averagingperiod.

• Ground level concentrations were computed without any decay co-efficient.

• The micro-meteorological observations made during the study periodfor EIA of 0.75 MTPA have been taken as input meteorological data.Calm wind conditions recorded during study period were alsoconsidered.

• Terrain for both the sources and the receptors has been considered

Simulation model for prediction of ground level concentrations due tofugitive emissions from storage areas

Since the fugitive dust is a function of the area of the stack yard and thestandard international emission rates adopted per unit area, and since thereis no change in the area of the stock yards, therefore, there is no change inthe inputs or outputs of the FDM due to enhancement of capacity.

For estimating the increase in the air pollutants due to raw material stockyard, fuel stock yard (coal) and fly ash storage area, FDM model is beingused. Fugitive Dust Model (FDM), which is a computerized air quality modelspecifically designed for computing concentration and deposition impactsfrom fugitive dust sources. The sources may be point, line or area sources.The model has not been designed to compute the impacts of buoyant pointsources, thus it contains no plume rise algorithm.

The model is generally based on the well known Gaussian Plumeformulation for computing concentrations, but the model had beenspecifically adapted to incorporate an improved gradient transfer depositionalgorithm. Emissions for each source are apportioned by the user into a

4.2 Mitigation Measures

The likely impacts on air quality during the construction phase arecomparatively low. It requires preventive maintenance of all trucks,earthmovers and construction equipment, spraying of water on disturbedareas, water spraying during loading and unloading operations andtransportation to be carried out in covered trucks.

However, during operation phase, the various operations would dischargehuge quantities of particulates and gaseous pollutants, which must becontrolled before discharge into atmosphere. Following mitigation measuresare underway and shall be continued.

a) Construction phase

Major sources of air pollution are dust and fumes from constructionoperation and equipment, welding fumes, and radiation during non-destructive testing of weld joints. Water spraying on material to be handledbefore beginning work and spraying on unpaved surfaces twice a day willimprove the working conditions and minimize dust pollution. The designatedareas for roads and parking spaces shall be black topped at the earliest.Transport vehicles shall be maintained leak proof to avoid spillage of rubbleand soil. Welding operations shall be carried out within cordoned areas.

As per AP-42 of US EPA, the recommended measures for various activitiesduring construction phase are summarised in Table 9 .

^ Chemical stabilization usually cost-effective for relatively long-term orsemi-permanent unpaved roads.

^^ Excavated materials may already be moist and not require additionalwetting. Furthermore, most soils are associated with an" optimummoisture" for compaction.

b) During operation phase

The air quality prediction exercise done in the previous section indicatesmaximum increase in ground level concentration of PM10, PM2.5 SO2 andNO2 when superimposed over the existing ground level concentrations, willresult in concentrations within the required standards. This has beenachieved by adopting following control measures:

Use of After Burning Chamber in the DRI units for combustion of CO.

Use of high efficiency electrostatic precipitators in case of DRI kilns tolimit SPM level below 50 mg/Nm3.

Keeping appropriate stack height as per CPCB norms.

Dust extraction system with bag filters shall be provided at differentplaces, such as kiln inlet area, crushing unit, cooling out let area tosuppress SPM level below 50 mg/Nm3.

Dust and fume extraction systems will incorporated in the blastfurnaces and the induction furnaces for control of dust and fumes.

Rungta Mines Ltd.

Addendum EMP for Enhancement of Kamanda Steel Plant from 0.9 to 0.97 MTPA 17

High efficiency ESP is there for the existing phase and shall beinstalled for the expansion phase for the FBC boiler to control PMemissions below 50 mg/Nm3.

Fugitive dust due to handling of coal and iron ore and other rawmaterials etc. will be controlled by sprinkling /dust extraction system.

Waste heat recovery boiler to utilize waste heat for generation ofsteam.

Leakage from the equipment, ducts and transfer points shall beregularly checked and stopped.

Development of green belt will help to check air pollution

All fugitive emissions will be minimized.

Regular monitoring and awareness among workers will help incontrolling air pollution

Fugitive emissions control

Control and mitigation measures for abatement of fugitive dust emissionsare as follows:

1. Dust extraction systems, with bag filters have been provisioned at alltransfer points and crushing/ grinding operations. Dust laden air isdrawn through ID Fans, and passed through bag filters to bring downthe dust content below 50 mg/Nm3. The clean air is discharged intothe atmosphere.

2. Raw materials and finished product are stored in covered sheds.

3. Water sprinkling is done regularly over all open storage dumps of solidwastes and raw materials.

4. In order to prevent the spread of fugitive dust, green belt of adequatewidth will be there all along the plant boundary.

The air quality management measures remain same as proposed in theearlier EIA for EC dt. 06.11.2017, addendum EIA dated 08.03.2019 and ECdated 19.07.2019 except blast furnace which is proposed to now use drygas cleaning technology instead of the earlier proposed wet gas cleaningplant, to eliminate the use of water.

Total fresh water requirement of the entire 0.97 MTPA complex, underenvisaged operating conditions, is estimated to reduce to 1463 from thesanctioned 2448.81 m3/hr. Water shall be continued to be sourced fromKaro river and additional proposed source is from Karo and Kurarhi riverboth. The water consumption break up has been given in Table 30 of theuploaded Pre-Feasibility report. The reasons for reduction in waterconsumption are several as follows:

Rungta Mines Ltd.

Addendum EMP for Enhancement of Kamanda Steel Plant from 0.9 to 0.97 MTPA 19

In DRI, the cooling system (diameter & length of rotary cooler)remains unchanged and throughput decreases, therefore, there isslight reduction in specific water consumption. The fresh water makeup water requirement decreases because waste water (blow down)of WCC of power plant is being used as a make up water

With the commissioning of rolling mill, hot charging of billets is takingplace, thus, reducing the water requirement for cooling hot billets(1100°C) to 500°C for handling with electromagnet

In case of blast furnace closed water circulation system has beenchosen over open water cooling system and dry gas cleaningtechnology will be opted for instead of wet gas cleaning plant

In sinter plant also closed water circulation system has been chosenover open water cooling system

In case of rolling mills, since water required for cooling of rollsremains constant as production increases, hence specificconsumption is reduced.

In case of power plant, use of Air Cooled Condenser has resulted indecrease in make up water even below the standard.

Reuse of waste water has reduced water requirement for utilities.

6.2 Waste water generation from various sources

The waste water generation will decrease from 328 to 142 cum/hr, i.e. by186 cum/hr. Details of effluent generation from each plant is given in Table11.

No waste water is anticipated from DRI plant, coke oven plant and ferroalloys plant as all the water consumption losses will be in form ofevaporation.

The waste water sources will remain same and its management will alsoremain same as given in the EIA submitted for EC dated 06.11.2017,addendum EIA dated 08.03.2019 and EC dated 19.07.2019. The additionalmeasures required will be enhancement of common monitoring basincapacity to cater to the increase of 10 KLH. Entire waste water will bereused.

6.3 Waste water sources and treatment

Waste water generation from the operation phases will be on account of thefollowing activities which are described along with the treatment option:

1. The prevention and control of water pollution aims at conserving themake-up water by recycling the waste water. However, occasionallysmall quantities of effluents have to be discharged to prevent build upof excess dissolved solids. Industrial wastewater comprising blowdowns from cooling towers and boilers, DM unit regenerationwastewater, wastewater from water pre-treatment, effluent from servicewater uses like plant washings, leakages, etc. and effluents from SMS,rolling mill, ferro pellet plant & sinter unit contain high TDS & SS andwill be collected in a “common monitoring basin (CMB)” sump andutilized for dust suppression, ash handling, fly ash brick making andhorticulture.

2. DM Plant- In the chemical water treatment plant, acidic and alkalineeffluents are generated during the generation of cation /anion and themixed bed exchangers. The effluents from the chemical watertreatment plant will be led to a properly sized impervious, neutralizationpit. Normally these effluents are self-neutralizing. But, provision will bemade for dosing lime into the neutralizing pit to ensure the sufficientlyhigh pH value before these effluents are reused.

3. Run off (during rainfall days and monsoon) from coal and iron orehandling areas and run off from solid waste storage & handling areas.will be routed through catch pits of sufficient volume to settle outsuspended solids present in the storm water runoff.

4. Washery waste water will be recycled in its five stage treatmentsystem and 100% reuse achieved by recirculating the treated waterback to the washery.

The media water after being used for washery operations will bescreened through a five stage clarification process and all thesuspended particulate matter would be squeezed and the clear water isrecycled back to the process. The five stage clarification can beschematically depicted in Fig 1.

FIG 1: PROPOSED FIVE STAGES OF CLARIFICATION IN WASHERY

5. In the iron ore beneficiation plant , the waste water will be sent to thetemporary tailing pond wherefrom the overflow will be recirculated backto the iron ore beneficiation plant. 100% reuse is anticipated.

6. Sewage from buildings - Sewage from the toilets, washrooms andcanteen are currently treated in septic tank system but with increasingmanpower, it is proposed to install a sewage treatment plant and aftertreatment use treated waste water in horticulture.

The plant sanitary sewage from ablution blocks etc will be segregatedfrom industrial waste and routed to the sewage treatment plant (STP)through sewer network. The STP shall constitute of Bar screens, Oiland grease Trap, Equalization tank, Aeration tank, Clarifier tank, Filterfeed tank, Pressure sand Filter, Tertiary Treatment and treated effluentwater tank. The schematic diagram of the sewage treatment plant isgiven in Fig 2.

During the monsoon requirement of water for dust suppression andgreen belt irrigation will be drastically reduced. Hence excess treatedwaste water will have to be discharged. The water quality will be wellwithin the stipulated norms. Thus, on the whole the impact on quantityand quality of water is manageable.

7. Workshop: Oil & grease during repair and maintenance of machineryand vehicles will get spilled for which the water collected in theworkshop will be passed through oil-water separator (OWS) to removeoil & grease. The water from plant washing or maintenance work willalso be passed through OWS to collect oil & grease, which will bestored in a separate container and disposed to authorized recyclingvendor.

6.4 Rain water harvesting

Rain water harvesting scheme is being implemented in the existing plant.Rain water harvesting structure of size 148 m x 3.5 m x 47 m and 26 m x 10m x 2.8 m have been constructed and a settling pit of size 37 x 13.2.5 mhas been constructed in NE direction of the plant to collect rain water of theentire catchment of the plant. The photographs of the existing structures areas follows:

Rain water harvesting is planned for 100% plot area. It is proposed tocollect the rain water in the surface water reservoir. The water that shall getcollected in the surface water reservoir is calculated as follows:

7.0 SOLID WASTE GENERATION AND MANAGEMENT

There will be change in the solid waste quantities due to enhancement ofcapacity which are given in Table 12 along with the management measures.

It can be seen that the solid waste generation is reducing overall. The out ofplant movement of solid waste reduces due to reduction in SMS slag andincreases due to unutilised portion of RM-mill scale only, which will broadlybalance each other. Thus, solid waste movement outside plant will havenegligible impact on traffic volume.

The management of construction waste and other wastes, details ofdumping area and fly ash management scheme shall remain same as perthe proposal given in the EIA submitted for EC dated 06.11.2017,addendum EIA dated 08.03.2019 and EC dated 19.07.2019.

9.0 TRANSPORTATION

The transportation routes will remain same and the management of trafficwill also remain same as given in the EIA submitted for EC dated06.11.2017, addendum EIA dated 08.03.2019 and EC dated 19.07.2019.However, there will be increase in the number of trucks w.r.t. enhancementfrom 0.90 to 0.97 MTPA. There will be increase of 174 nos. of truck (to andfro) due to increase in raw material and 112 nos. of trucks (to and fro) fortransportation of products. This works out to approximately 12 trucks perhour or increase by 1 truck every 5 minutes.

No alternate method of raw material transportation has been studied asmaximum possible material is already moving and will move through roadsand railways, as already optimised.

The local infrastructure of the area such as road network is adequate tohandle the additional traffic and no additional infrastructure needs to beconstructed.
