5 In Bankura area Soil carbon is 0.3 %.

Moisture in soil sample taken up to 50 cm

depth, as reported needs to be justified

The organic carbon is an indicator of the

fertility of soil. The organic carbon content

have been checked at 8 points located in the

vicinity of the plant. Out of eight points, the

one at Barjora has come as 0.3 %. The

location of the sampling point is found to be

a patch of up land devoid of any vegetative

growth. This may be the reason for low

organic carbon.

Except for this location other locations the

OC % is higher varying from 0.9 to 1.3.

Another point at Tickergram shows 0.4 %

probably because it is a reclaimed area filled

with bottom soil.

Annexure-3

AAQ values are as high as 95.30 µg/Nm3 at certain places. No explanation is available. Reasons for the higher values be given along with mitigation plan shall be furnished.

a) The project site is located in an industrial estate locality namely the Plasto Steel Park, in

Barjora block of Bankura which is well in the proximity of another industrial hub Durgapur.

As per EIA report submitted the area is having as many as 24 numbers of industries in the

vicinity i.e. within 10 Km of the radius of project location.

b) Secondly there may be higher emission load of some of the industries due to process upsets

which may be transient. But this would have resulted in showing higher AAQ level in

ambient air.

The above points clarify as to why the AAQ values have been high at certain places.

Mitigation Measures:

1. There are number of industries in the cluster which contribute to the ambient air quality.

Many of the industries may be operating sticking to old emission standard of 150mg/m3.

Upon enforcement of the standard emission limit of 30 mg/m3 the ambient air quality will

improve shall significantly.

2. M/s STPL on its part shall take up modification measures of its pollution control measures

to reduce the stack emission of its Ferroalloy furnaces which has been deliberated in point

No I. above. The scheme to meet 30 mg/m3 norm of stack emission shall be completed by

December 2020.It will be done by phase manner and completed end of December 2020.

3. Another point for increase in particulate concentration in the ambient air is fugitive

emission. The movement of vehicular traffic in the arterial roads without black topping or

concreting may be contributing for high particulate level in ambient air. Regular water

sprinkling shall be done on road.

4. Water spraying shall be done at unloading and loading point .In dry months water

spraying shall be done on heaps of storage materials i.e. minerals and coal.

Annexure-4

Corporate Environmental Responsibility (CER) Budget Allocation according to Activities

(As per the provision of “OM No. F. No. 22-65/2017-IA-III dated 01 May 2018") The project cost for M/s. Sonic Thermal Private Limited, Village: Namabandha-Sitarampur, P.O: Ghutgoria, Block: Barjora, Dist.: Bankura, West Bengal was Rs. 80.00 crore at the time of construction in the year 2006. The current proposal is only for modification of product mix. There is no need of additional land, machinery or budget for it. However, being a brown field project, the Corporate Environment Responsibility (CER) programme as per the provision of OM No. F. No. 22-65/2017-IA-III dated 01 May 2018" attracts 1% of the project cost, which amount to Rs. 80.00 lakh (mentioned in the revised EIA & EMP - para 8.0 of Chapter – 8). As per the guideline no. (ii) of the above notification, M/s. Sonic Thermal Private Limited is committed to spend Rs. 80.00 lakhs based on public hearing demand conducted on 21.12.2018 at Barjora Panchayat Samity Meeting Hall in presence of ADM, Barjora and other concerned authorities.

DETAILS OF ROOF TOP RAINWATER HARVESTING WITHIN PREMISES

AND ARTIFICIAL RECHARGE MEASURES OUT SIDE THE PREMISES

In compliance to the query raised by Ministry of Environment, Forest & Climate Change,

Delhi details of roof top rainwater harvesting and artificial recharge measures by adopting

village pond have been furnished herewith.

ROOFTOP RAINWATER HARVESTING

Rainwater harvesting is the technique of collection and storage of rainwater at surface or in

sub-surface reservoir before it is lost as surface run-off. The augmented resource can be

harvested in the time of need. Artificial recharge to groundwater is a process by which the

groundwater reservoir is augmented at rate exceeding the one under natural conditions of

replenishment

Rooftop rainwater harvesting structures are to be constructed in the premises of M/S Sonic

Thermal Pvt. Ltd. The collected rainfall at first is to be passed through a filter so that the water

can be drained into suitable structures. A provision to drain out portion of the first rainfall has

been designed, as it would flush out the dirt.

Rain water harvesting is an important activity to conserve the rainwater for reuse and thus

reducing the overall raw water consumption for domestic requirements.

In the project area, the rainwater available from roof tops of buildings that goes as waste

can be utilized gainfully at the time of need by way of surface storage. The rainwater

harvesting system has been designed in such a way that it does not occupy large space for

collection.

In order to harvest the rain water within the project premises it is recommended to harvest

roof top rain water from buildings. For this purpose quantity of rain water that could be

generated is calculated below.

Runoff = Rainfall X Catchment area X Runoff coefficient

Annual Rainfall = 1.19 m

Total Run-off: Roof Top

Intensity of rainfall = 1.19 m

Drainage area in sqm = 11207.0 m2

Coefficient of run-off = 0.85

Therefore, runoff = 0.85 x 1.19 x 11207.0 = 11335.88 m3

Annexure-5

Total Run-off: Road Area




Therefore, runoff = 0.70 x 1.19 x 5684.00 = 4734.77 m3

Total Run-off: Open Area




Therefore, runoff = 0.60 x 1.19 x 23811 = 17001.05 m3

Total Runoff Load = (11335.88 +4734.77 +17001.05) m3

= 33071.7 m3/annum

From the above computation, it is evident that a total quantum nearly about 33071.7 m3 of

rain water can be fruitfully harvested annually by constructing storage tank in the premises

& recharge pits.

DESIGN OF THE STORAGE TANK

The storage capacity of the tank is considered to store rainwater available from rooftop of the

buildings. The capacity of the storage tanks has been designed to accommodate rainfall from

the roof area.

The size of the storage tank is suggested to be 30 m (length) x 10 m (breadth) x 2.5 m depth).

Artificial Recharge of Ground Water through the Village Pond:

It is noteworthy that, the Total Fresh Water Requirement of the project is 166980 m3 per

annum. So, in order to ensure the enhanced quantum of recharge, the plant authority has

planned to renovate and maintain 1 no. of private pond existing nearby with due consent of

villager. The pond is in Saharjora mauza the consent agreement is also attached.

The industry has adopted pond near the industrial complex in order to recharge the rain

water. It is proposed to adopt the village pond to take-up recharge to ground water of the

pond water, which is overflowing to adjacent areas during monsoon period. The recharge to

ground water in the pond area via pond cleaning and desilting will result into rise in water

levels in the village tube-wells and increase the supply of water to the lands adjacent for

irrigation purposes. Thus recharge schemes in the pond will benefit the area.

Annual Water requirement = 166980 m3/annum

Recharge Requirement = 100% of the Ground water withdrawal

i.e. 166980 m3/annum.

Recharge through pond = 140400 m3/annum

RWH within premises = 33071.7 m3/annum

Total rain water harvesting and ground water recharge = (140400+33071.7) m3/annum

= 1,73,471.7 m3/annum

Thus the proposed rain water harvesting within premises and ground water recharge through

pond will be 1,73,471.7 m3/annum and it is higher than the required quantity of 166980

m3/annum.

Introduction

Chromium is one of the most common toxic heavy metals found in the environment. It exists in the common oxidation states as hexavalent Cr (VI) and trivalent Cr (III). Chromium as Cr (III) is highly immobilised in the solid waste slag matrix and hence does not leach out. Moreover trivalent chromium is far less toxic than its hexavalent counterpart. On the other hand Cr (VI) is highly mobile under all environmental conditions and it causes all the toxic effect. As per Occupational Safety Health Administration (OSHA), USA, the major health effects associated with exposure to Cr (VI) include lung cancer, nasal septum ulcerations and perforations, skin ulcerations and allergic and irritant contact dermatitis. Toxicity of chromium ranges from pulmonary to dermatological problems. As per EPA (2000), it is a suspected carcinogen. That is why there is stringent USEPA Toxicity Characterising Leaching Study (TCLP) standard such as 0.1mg/l for Cr (VI) and 5.0 mg/l for total chromium (USEPA, 1990). There also exists stringent Indian discharge standard such as 2.0 mg/l for total chromium (total Cr) and 0.1 mg/l for Cr (VI)

Ferrochrome is the most common alloying material for the production of different grades of stainless steel. Ferrochrome is manufactured through direct smelting in Sub-merged Arc Furnace (SAF) at a temperature above 1500 0C.The furnace has the suitable system for tapping heavier metal and lighter slag and their handling.

In the ferrochrome manufacture the main contributor to solid waste is from the dust collected in in the bag filters and the Fe-Cr slag after the metal recovery section.

Management of Bag Filter Dust

The unit shall use Chromites ore dust. It has a briquette plant. The dust collected in the bag filter will therefore contain more of hexavalent chromium which is considered hazardous. Utmost care is to be exercised in handling the bag Filter dust. The company envisages to install a pneumatic conveying system for transfer of dust from the bag filters if each furnace to the silo. From the silo the dust is again conveyed to the briquetting plant by pneumatic conveying. The risk involved and the management plan to handle the risk is given in the table below

The dust so collected is recycled back to the furnace through the briquetting plant. A description of briquetting plant has been given in Chapter II of EIA at Section 2.4.3iii. Proper care is exercised in handling the dust as per MSDS of Chromium.

Management of Ferrochrome slag:

Molten slag is lighter than the molten Fe-Cr alloy. It is tapped out through the tape holes in ladles and is allowed to cool. . Ferrochrome (FeCr) slag is found to consist of mainly silica, alumina and magnesia with significant amounts of chromium and iron oxides in the form of Partially Altered Chromite (PAC) and entrained ferrochrome alloy.

Annexure-7

There is a generation of 1–1.2 MT of solid waste slag for each MT of ferrochrome product. The waste slag material can be made available in different sizes under different cooling conditions and after material recovery. It contains about 6–12% deleterious substances like chromium as chromium oxide and has the potentiality of releasing hazardous chromium compounds to the environment restricting its use and disposal. Chromium is one of the most common toxic heavy metal found in the environment. It exists in the common oxidation states of hexavalent chromium Cr (VI) and trivalent chromium Cr (III). While chromium as Cr (III) is less mobile and less harmful, Cr (VI) is highly leachable and extremely toxic under all environmental conditions. As per Occupational Safety Health Administration (OSHA), the major health effects associated with exposure to Cr (VI) include lung cancer, nasal septum ulcerations and perforations, skin ulcerations, and allergic and irritant contact dermatitis etc. Toxicity of chromium ranges from pulmonary to dermatological problems. As per US EPA, it is a suspected carcinogen. That is why there exists stringent Indian discharge standard such as 2.0 mg/l for total chromium (total Cr) and 0.1 mg/l for Cr (VI).

Air cooled slag is crushed in order to extract any additional metal remaining in the slag by density separation or jigging process. Given below is a description of process jigging plant.

Metal Recovery Plant:

The ferroalloy slag consist some portion of valuable ferroalloy material which can be obtained in a directly saleable condition and can be sold at reasonably good market rates as compared to the main ferroalloy product. The Metal Recovery Plant is being used to recover this portion of metal from slag.

Certain portion of slag is conveyed to Metal Recovery Plant (MRP) wherein it is crushed as to extract good quality Ferrochrome from the slag waste. This process involves the following :

Crushing and screening of metal containing slag. Separation of metal from slag. Re-crushing of middling to realize additional metal

The process flow of Metal Recovery Plant is given in Fig below.

Annexure-7

Crushing and Screening:

This circuit produces a crushed slag having a narrow size distribution, which would aid the metal liberation in further stages. Cone crushers are used to maximize shear at metal-slag interfaces. Wherever possible, the multiple cycles of crushing are maintained in a close circuit so that the minimum crushed size is achieved. To minimize fines, the reduction ratios are maintained as low as possible.

Separation of Metal from Slag:

This involves two – stage recovery jigging process; known as the ‘Coarse Jigging’ and ‘Fine Jigging’. During the course jigging stage, the cut density is set with an aim to recover clean metal and not with a focus on recovery. The coarse fraction is crushed to have an output in the form of saleable coarse alloy. An under-bed air pulsated jig with a float control system is on the discharge gates. A hydro-dynamically stable float is positioned in the jigging bed.

Later during the Fine Jigging, the cut density is lowered to focus on recovery. Since the material is fine, a strongly pulsed Jig is not required here. Only a single stage is required to utilize ‘through the bed’ Jigging as the material quantity reaching this stage is only about 5% of the total feed. The output of this stage is in form of fine tailings and slimes.

Annexure-7

The final disposed middling from coarse jigging and very fine metal from fine jigging are used for furnace feed.

Re-crushing of Middling:

The re-crushed middling are returned for re-jigging to recover additional material.

The throughput material (slag) requirement in an MRP (Metal Recovery Plant) is 3 times of its output. i.e 3 MT of slag needs to be fed to achieve 1 MT of saleable ferrochrome. The feed size specifications shall be provided by the technology supplier based on the final equipment design parameters. The standard composition of High Carbon Ferro chrome (HCFC) is as given below:

Chromium - 57% to 63% Carbon - 6-8% Silicon - 4% Phosphorus - 0.0025-0.03% Sulphur - 0.03% Max

In STPL ferrochrome plant wet jigging process is adopted. The slag so separated in the process is carried to slag storage shed. The generated slag is then subjected to TCLP test and if the hexavalent chromate is found below the specified hazard limit of 5mg/L(US EPA) for total chromium , total chromium of 2 mg/l and o.1 mg/l for Cr-(VI) in the Indian discharge standard. It is stored in a separate heap.

There are number of options for utilisation of non hazardous slag.

It is used as road base material in road construction. It is used as a concrete aggregate. It can be used in the manufacture of Portland cement. It can be used in the manufacture of slag cement. It can be used for filling of the evacuated mines

If the particular batch of slag is found to contain more than the specified limit in TCLP test, it is taken to storage shed where it is stored on impervious flooring. Normally many of the Fe-Cr factories operating in the eastern zone of India find that the TCLP test results are within the limit.

The hazardous slag is transported by truck covered with suitable tarpaulin cover by authorised hazardous waste TSDF operator. The following risks are identified and Management Plan for handling of risk also mentioned below..

Annexure-7

facility is already having a developed green belt. However, in keeping with the specific ToR

conditions the company will develop green belt on stipulated 40% land of plant area i.e.

over 6 acres of land.

The greenbelt development plan aims to overall improvement in the environmental

conditions of the region. The plan with a five-fold objective addresses issues such as

providing sink for air pollutants likely to emitted from the project; enhancing the forest

cover for increasing the biodiversity of the region; providing aesthetic value to the project

area enhancing the ecological equilibrium of the area; and to a large proportion in

combating soil erosion.

It is proposed to develop greenbelt around the periphery as well as along roadside/and sub-

paths of project area totaling about 33% of land area in line with the National

Environmental Policy 2006 of Government of India. STPL has developed green belt in and

around plant premises and proposes further development the action plan for green belt

development is given below.

Criteria for selection of Species: 1. Tolerance to specific conditions or alternatively wide adaptability to Eco physiological

conditions.

2. Rapid growth

3. Capacity to endure water stress and climate extremes after initial establishment.

4. Differences in height and growth habits Pleasing appearances Providing shade

5. Ability of fixing atmospheric Nitrogen

6. Improving waste lands.

With the above criteria in mind, green belt development work will be undertaken on area of 6 acres. About 600 saplings will be planted per acre. The details of existing Green Belt and Development of Green Belt Plan for the proposed project are given below. The existing plantation has been done alongside the boundary wall and in the vacant land earmarked for the purpose. The plants in the existing green belt include Devil Tree (Alstonia scholaris), Mahaneem (Melia azadiracta), Gulmohar (Delonix regia), Acasia (Acacia auriculiformis), Am (Mangifera indica), Silk Tree (Albizia procera) with survivility of 65%. The future development will also include above local species. The tentative implementation proposal for development of green belt and species to be planted is mentioned below.
