1.2 Water resources and quality

Following mitigation measures will be adopted to avoid impact on water resources

Construction equipment requiring minimum water for cooling and operation for

optimum effectiveness shall be chosen.

High pressure hose will be used for cleaning and dust suppression purposes.

Water harvesting measures would be taken.

Appropriate sanitation facilities, soak pits and septic tanks will be provided for the

workers onsite and offsite to reduce impact on water resources. Regular maintenance

will be done during the entire life cycle.

No discharge of construction wastes to surface water bodies or ground water will be

allowed during construction.

Efforts will be made for reuse of water and its conservation.

During Construction period in rainy season, the water quality is likely to be affected

due to the construction work and loosening of topsoil. This is likely to increase the

suspended solids in the run – off during heavy precipitation. In order to reduce the

impact on water quality, temporary sedimentation tanks will be constructed for the

settlement of the suspended matter. However, it is envisaged that the monsoon period

will be avoided for cutting and filling of earthwork. Additionally, following measures

will be taken to avoid the surface water pollution.

Soil binding and fast growing vegetation grass would be grown around the construction

site before commencement of construction activity to reduce soil erosion;

Appropriate sanitation facilities to be provided for the construction workers to reduce

impact on ground water resources and also to maintain hygienic conditions.

There is no possibility of ground water contamination, as no waste will be discharged

to ground water bodies during construction. However sewage generated during the

construction phase will be treated in the Septic Tank and Soak Pit. Wherever

construction wastes need to be disposed off on land or of - site, the same will be

disposed off in a proper manner.



CES, BHOPAL 5

1.3 Air Quality

During Construction period, there is likely hood of generation of dust and NOx emission. This

can be attributed to leveling activity and vehicular movement. The transport vehicles using

petrol or diesel will be properly maintained to minimize smoke in the exhaust. Since, there is

likelihood of fugitive dust from the construction activity, water sprinkling will be done. In

addition to this following measures will be taken during the construction phase to reduce the

impact on the air quality.

Any vehicle not meeting the vehicular pollution standards will not be allowed within

the construction activity.

Water will be sprayed by water tankers during dust generating construction activities

e.g. excavation, crushing/demolishing, concrete mixing, material handling etc. to

suppress dust; and

Vehicles delivering loose and fine materials like sand and fine aggregates shall be

covered by tarpaulin to reduce spills on roads.

The height from which excavated materials are dropped shall be controlled to a

minimum practical height to limit fugitive dust generation from unloading.

The random Ambient Air Quality Monitoring shall be done to ensure that the

significant impacts are being mitigated adequately.

1.4 Noise Level

The noise impact on the surrounding population during the construction phase will be within

the acceptable limits. High noise generation equipment, if used will be operated during the

daytime only and completely restricted during night hours and this eliminates any possible

discomfort to the nearby communities. Community noise levels are not likely to be affected

because of the vegetation and likely attenuation due to the physical barriers. The following

recommendations will be implemented:

Provision of insulating caps and ads at the exit of noise source on the machinery;

Construction equipment generating minimum noise and vibration be chosen:

The use of damping materials such as thin rubber / lead sheet for wrapping the work

places line compressors, generators sets.

intervals during construction phase to conform to the stipulated standards both during

day and night time.

1.5 Solid /Hazardous Waste Management

The hazardous materials used during the construction may include petrol, diesel, Welding gas

and paints. These materials will be stored and handled according to the MPPCB guidelines.

Diesel and other fuels will be stored in separate enclosures;

Wherever possible, hazardous raw materials to be substituted by non- hazardous

materials, e.g. Cleaning solvent can be replaced with film –free biodegradable cleaners.

Usage of non chlorinated strippers instead of strippers containing methylene chloride

and substitution of water based paint for oil based ones;

Separate storage of waste paints, thinners, contaminated rags and brushes will be

adopted.

Vehicle maintenance area to be designed to prevent contamination of ground water by

accidental spillage of oil; and

Maintaining appropriate inventory control.

1.6 Site Security

Adequate security arrangement will be made to ensure that the local inhabitants and the stray

cattle are not exposed to the potentials hazards of construction activities.

1.7 Traffic Pattern

Heavy vehicular movement will be restricted to daytime only and adequate parking facility is

being provided.



CES, BHOPAL 7

1.8 Solid Waste Generation

The solid waste generated during the construction phase is usually Excavated earth material

and Construction debris. Excavated earth material will be reused for backfilling between

foundations; to fill up the low -lying areas and whereas, topsoil will be reused for

Landscaping/Greenbelt development purpose. Construction debris as far as possible will be

reused / recycled for back filling / sub base work for roads & pavements.

1.9 Ecological Aspects

aid boxes are provided in each section of all shop floor departments. All weather

related precautions are taken care of.

In rainy season raincoats are provided to the personnel who are required to work in

open.

1.12 Operation Stage

1.12.1 Air Environment:

The mitigation measures needs to be adopted during the operation stage to control the

negative impacts on air environment of the surrounding of the project area given below:

Dense green belt is planted around the dust generation points at surface.

Trees are planted on both sides of the roads used for transportation in order to arrest

dust.

Afforestation around the unit to act as barrier

Water sprinkling along the haul road

Proper maintenance air pollution control equipment

D. G. Set (500 KVA) Acoustic Canopy shall be installed.

The following steps shall be taken for smooth functioning of Bag filters.

1. Dust from the bag filters shall be disposed off on regular Intervals which prevent

pressure drop across the bag filter and improve the Suction efficiency.



CES, BHOPAL 10

2. Manometers shall be provided to check the pressure drop across the Bag filter so as to identify the leakages/ chockage of the bag filters.

3. Maintenance schedules shall be made for checking the bag filters, ID fans shall be followed.

4. Industry will keep the record regarding their dust generation from air pollution control systems.

Air Curtain

Most of the furnaces are using man-coolers installed on the charging platform to provide

comfort to the workers working near the furnace area because of intense heat. But it has been

observed that the workers are directing these man-coolers towards the furnaces to throw

away the high temperature dust emissions being generated during furnace operation. This

would result in poor suction efficiency of the air pollution control device with high dust level in

the work zone environment as well as in the ambient air. To counter this effect, the company

will install APCDs of higher air handling capacities with higher energy consumption.

An air curtain is recommended to be provided to provide the cool air to the workers without

interfering with the operation of APCD. The schematic arrangement of the air curtain is shown

as under Fig. 9.1:

Figure 1.1 air curtain Containment system

It has been observed that most of the induction furnaces have provided low canopy hoods for

the containment of dust emissions being generated from the furnaces during melting of the

raw materials. The raw materials i.e. scrap and sponge irons are being charged into the



CES, BHOPAL 11

furnace throughout the cycle time of around 2 hrs. In low canopy hoods, the distance between

the furnace and the hood is being maintained as 0.4- 0.8 m. It has been observed that most of

the furnaces are not able to keep the hood on the furnace because of the operating problems

faced during poking of the charge materials into the furnace and the irregular size & shape of

the scrap. Moreover the suction of the emissions into the hood was also affected by the man

cooler installed on the charging platform and the cross currents. Although the man cooler is

being provided for the comfort of the workers because of the intense heat on the platform but

the workers are using this high RPM fan to throw away the dust emissions / fumes being

generated from the furnace. Moreover it has been observed that number of industries is

upgrading their furnace capacity without upgrading the capacity of the pollution control

device. This would lead to poor suction efficiency of the air pollution control system with high

dust levels in the work zone environment. The dust coming out from the sheds would further

deteriorate the quality of the ambient air.

The containment system shown in the figure 1.2 was found effective in containing the

emissions and recommended for proposed plant of Meenakshi Metal Industries LLP at Sagar

Figure 1.2 containment system



CES, BHOPAL 12

Figure 1.3 Primary & Secondary Air Pollution Control System



CES, BHOPAL 13

In the above said containment system, the hood is placed at a height of 1.2 m above the

furnace so that the workers will not face any problem during poking of the raw materials and

irregular size & shape of the scrap. Two side hoods are proposed to take care of the cross

currents. The pivot arrangement for swiveling the hood is proposed on the pouring side of the

furnace with underground ducting to air pollution control device. This type of arrangement

will not provide any obstruction to the movement of overhead crane. The proposed

containment system would increase the volumetric flow rate requirements. Alternatively for

the furnaces which are using clean scrap and keeping the lid of the furnace closed during

melting of the raw materials in the furnace, annular ring shall be provided along the

circumference of the furnace with side suction so as to contain the emissions. The figure

showing is Fig. 1.4 the same is as under:

Figure 1.4 Containment System

1.13 Water Environment

Water requirement for proposed project will be met from Ground water /MPAKVN Sagar. The

water will be used mainly for cooling purposes. The proposed steel making and rolling facility

shall have efficient cooling water recycling system with minimum drift was by using proven

cooling tower and heat exchanger. For the soft water circulating in the closed loop , a

dedicated softener plant has been proposed and the waste , water shall be used for water the

coconut trees .Plants shall also be planted in the vicinity of water plant.

There is no any effluent generation from this process. The quantity of domestic generated of

about 25m3/day will be treated in the existing STP. Apart from above, following additional

measures will minimize operational impacts:

There will be no any effluent water in this process

Closed circuit cooling system will be provided in cooling of products. Hence there will

not be any waste water generation from process and cooling in the steel plant. The

only wastewater that is generated will be sanitary waste water..

Use of high pressure hoses for area cleaning

For removal of oil, oil skimmer will be provided, and collect in separate MS drums and

the clean water shall be reused for process of cooling.

Storm water drains shall be provided to avoid flooding in the proposed project site area

and provision will be made for runoff get diverted to recharge pits.

Rain water Harvesting sump of capacity 7480 cum shall be provided.

1.14 Water Conservation Measures

The treated water from STP shall be used for gardening and spraying of roads.

The softener will be used instead of DM water plant, and the rejects shall be used for

slag quenching.

Reduce blow-down/bleed-off by adjusting the Cycles of Concentration- If the Cycles

of Concentration limit for blow-down is set too low, then water will be drained sooner

than is necessary. Every time the tower is drained it must be refilled, which requires a

substantial amount of water. By increasing the Cycles of Concentration, it is possible to

get the maximum utilization from every kiloliters of water. To determine the optimum



CES, BHOPAL 15

level of Cycles, a trained water treatment professional will be consulted. Also, it will

insure that proper chemical treatment will be done for maximizing the Cycles of

Concentration in order to minimize water consumption.

1.15 Roof Top Rain Water Harvesting

The roof top of the plant area, raw material storage area, finished goods area and office

building occupy -11,000 sq.m areas. These roof tops will be used as roof catchments for the

rain fall falling on the roof. Considering the losses and the fact that the first rainfall shower is

not to be used for recharging of ground water only 85% of the rainfall falling on the roof top

can be harvested. Thus the amount of rainfall harvested from the roof top is as follows:

Roof top area : -11,000 sq.m

Average Monsoon rainfall: 800 mm.

Total rainfall on roof top: 11,000 x 0.8 = 8800 cum.

85 % of the total rainfall that can be harvested = 7480 cum.

Thus 7480 cum of rain water can be used for recharging the groundwater in the area.

The roof top rainwater harvesting structures (Recharge wells Borewells/Dugwell)

proposed to be constructed as shown in Figure 1.5.
