Point No. 1 AAQ Values in Siltara are high. Therefore, action plan to limit the PMemissions from the plant to less than 30 mg/Nm3 shall be submitted.

Reply:

All the stacks envisaged under the proposed expansion will have the emission level less than30 mg/Nm3. As far as existing stacks are concerned, the PM emission level is 50 mg/Nm3asper CECB Consent to Operate.

Therefore, GPIL shall achieve emission level below 30 mg/Nm3 in a time bond manner. Thedetails of existing as well as expansion stack details are enclosed herewith as Annexure-I.

With regard to the commitments to reduce emission level from our plant, the followingactivities are being/will be carried out on regular basis:

1. We will consistently bring down the emission level to less than 30 mg/Nm3.

2. Regular sprinkling of wateron stockyard to reduce fugitive emission.

3. Sweeping ofroads regularly with industrial vacuum cleaners and recycle the dustwithin plant.

4. Green belt all along the plant boundary is provided and to further strengthen greenbelt, avenue and gap plantation in the plant area shall be done.

5. All internal roads have been made pucca.

Point No. 5 Fourth hole extraction system shall be installed on SAF for fume extraction.

Reply:SAF emission is being captured by existing side suction and it is efficient for fumeextraction followed by air cooled heat exchanger & pulse jet bag filter and outlet emissionbeing achieved less than 30mg/Nm3. As per OEM installation of fourth hole is not feasible inSAF as it is a Semi Open Furnace. In case of EAF which is closed furnace, fourt hole isfeasible.In order to check possibility and feasibility of fourth hole extraction system, we haveapproached a leading expertto check feasibility for installation of fourth hole extraction onexisting SAF. Communication for the same is attached herewith as Annexure II.

Point No. 7 GHG emission inventory for the entire plant shall be prepared andmeasures to conserve energy shall be taken as annual targets.

Reply:

In the complex of Godawari Power and Ispat Ltd. (GPIL), the sources of GHG emission areas follows:

1. 7 MW Waste Heat Recovery Plant.2. 10 MW Waste Heat Recovery Plant.3. 25 MW Waste Heat Recovery Plant.4. 20 MW Biomass Power Plant, and5. 11 MW Coal Based Power Plant.

Based on our experience of CDM Projects which included the plants mentioned at 1, 2 & 3and Gold Standard Project at serial no. 4 above, we do have historical annual GHG inventorywhich are as under:

1. 7 MW Waste Heat Recovery Plant.

17,828 units of emission (average 2,547 units per MW)




1,59,926 units of emission (average 6,397 units per MW)

4. 20 MW Biomass Power Plant.


5. 11 MW Coal Based Power Plant.

Based on the above average figures of per MW generation at 1, 2, 3 & 4 the estimated annualemission units for 11 MW Coal based Power Plant can be put conservatively at 60,000 units.

While the above figures serve as a guide to stock taking of GHG inventory, it may be notedthat for fixing the annual target of energy conservation, we are guided by the targets fixed bythe Bureau of Energy Efficiency (BEE) of the Ministry of Power, Govt.of India. GPIL is oneof the Designated Consumers under PAT Scheme of Energy Conservation Act. In every PATCycle our energy conservation target is notified by BEE for our implementation.

Point No.10 Detail traffic study shall be conducted for the roads leading to plant gates.Details about vehicles parked on road side at day and night shall be furnished.

Reply:

A detailed Traffic Study has been conducted. Report is enclosed in EIA Report as AnnexureNo. VII.Traffic survey data clearly indicates that the existing road leading to plant gates arecatering to average density of traffic and it is expected that incremental increase in traffic dueto proposed expansion project will be marginal. There is dedicated road patch of 200 meterslength and 20 metres width before entry gate for waiting vehicles and there is sufficientparking space inside plant. Width of all the internal road in the Siltara Industrial Area is 15 to30 metres.

There is provision to park 110 - 120no. of trucks outside plant.

Average No. of Trucks parked at a time during day hours is 70-80&during night hours 30-40.
