CONCLUSION


Coal based Captive Power Plant

To carter the power requirement of the various plants, coal based captive power plant will be installed in which the

steam is produced in high pressure in the steam boiler due to burning of fuel (Imported Coal from Indonesia /

South Africa blended with Indigenous washed coal) in boiler furnaces. Super-heated steam enters into the turbine

and rotates the turbine blades. The turbine is mechanically coupled with alternator that its rotor will rotate with

rotation of turbine blades hence shall generate power.

1.1.3 Utilities

CONCLUSION


1.2.6 Noise Levels

Based on the noise monitoring results as mentioned in Table 1-3 , it is observed that noise level during day &

night time, in Residential area, were slightly higher which is due to vehicular movements in nearby highways.

1.2.7 Water Quality

Quality of Surface water (Pond)

It is observed from Table 1-4:

Atali Pond (SW 4) is worst polluted source where total 8 parameters are more than acceptable limits, whereas

Koliyad Pond (SW 3) pond is the least polluted sources.

Parameters such as TDS, Chloride, Sulphates, alkalinity, fluoride, total nitrogen and coliforms are above

acceptable limits in major pond sources, thus requiring necessary treatment if utilized for drinking purposes.

As per classification of inland surface water standards, analysis results for all surface water of all ponds could

be considered under Class “C” except for BOD values which range from 7 mg/l to 22 mg/l. This is due to

anthropogenic sources such as washing, bathing etc.

Quality of Surface water (Estuary)


The Quality of Narmada estuary (upstream and downstream) is nearly matching with class SW-I as per causal

water marine standards.

Quality of Ground Water


The presence of high TDS and Chlorides is imparted by saline geological formation.

The geological formation is having low storability since it is made up of fine sand and silt thus groundwater

supply will always be limited.

1.2.8 Soil Quality

It is observed from Table 1-7 that at different locations:

The porosity ranged from 55% (Koliyad village) to 61% (Jolwa village) and WHC varied from 67% (Rahiyad

village) to 77 % (Jolwa & Atali village);

M/S. GACL IN JV



CONCLUSION


The soil permeability was low to medium which ranged from 0.37 mm/hr (Jolwa village) to 12.5 mm/hr

(Kolliyad village), however soil texture in all the soil samples was clay loam, hence whatever variation observed

was mainly due to variation in organic matter content of soils;

The EC of soil ranged from 178 dS/m (Koliyad village) to 506 dS/m (Suva village), while ESP varied from 0.19

(Koliyad village) to 1.78 (Suva village);

These soils are neither saline nor sodic as ESP is < 5.0;

The pH of soil ranged from 7.86 (Koliyad village) to 8.26 (Jolwa village), which indicates that soils are neutral

to slightly alkaline.

The overall soil quality indicates that soils are normal as the area is located in GIDC and not under cultivation since

long and whatever salts were there are washed off or leached down due to rain water over the years.

WITH NALCO DRAFT EIA FOR PROPOSED NEW CHLOR-ALKALI PLANT, CPP & SYNTHETIC

ORGANIC CHEMICAL UNITS AT PLOT NO.: D II/9, GIDC, DAHEJ EXECUTIVE SUMMARY


1.2.9 Ecology & Biodiversity

There is no Wildlife Sanctuary, National Park, Reserve Forest or Sanctuary, Biosphere Reserve, Tiger / Elephant

Reserve, Migratory Corridors, breeding sites, nesting sites / grounds, foraging and resting grounds in the

project study area of 10 km radius.

Project Site / Core Zone

The core zone area is dominated by Prosopis juliflora. There is no tree species at site. Overall 11 species of

common flora were recorded from the core zone. Only 3 common species of birds were reported from the

project site. While, No direct or indirect evidences of mammals were reported from the core zone.

Study Area / Buffer Zone

Overall 104 species of flora were recorded from the buffer zone of the study area. On the behalf of the

qualitative analysis, the maximum species were trees (40) followed by herbs (27), shrubs (26), and grasses (5)

and climbers (6).

Overall 54 species of fauna were reported from the buffer zone of the proposed project. Canis aureus (Jackal)

was observed and rescued from the industrial drain of GIDC, Dahej, Phase II with the help of Forest department

during site visit. On the behalf of the qualitative analysis, the maximum species were Birds (39) followed by

Mammals (9) and herpetofauna (6).

Marine Biodiversity

Marine biodiversity study shows that, buffer zone supports phytoplankton, zooplanktons, benthos, fishes and

other marine fauna. Bombay duck (Harpadon nehereus) constitutes the dominant fishery (13%) of the region

of the total marine catch. The coastal water also serves as the migratory route for the clupeid Hilsa (Tenualosa

ilisha) on their way to the Narmada River for breeding and the outward route for the newly hatched juveniles

and some of the adults. This makes Hilsa fishery an important activity inside the Gulf and the estuarine region

of Narmada.

Status of Threatened Biodiversity

No any threatened species of plants were reported from the area under study while most of the fauna reported,

from the buffer as well as core zone falls under Schedule-IV of IWPA, 1972 except Indian Peafowl (Schedule-I,

Lc). Among recorded faunal species, none of the species can be designated as an endemic.

Agriculture Pattern

The crops grown in this region was mostly Tuver (Cajanus indica), Wheat (Triticum aestivum) and Cotton

(Gossypium herbaceum) during rainy seasons. Other crops like Bajra (Pennisetum typhoides), Jowar (Sorghum

bicolar) and Divel (Ricinus communis) are grown in some area. The vegetables grown in the study area are,

Rigan (Solanum melongena), Tomato (Lycopersicon lycopersicum) and Val, Valpapadi (Lablab purpureus).

Horticulture activity is very less. The cultivation is essentially through rain water and in some area through

GIDC water supply.

1.2.10 Socio Economic

The summary of the social survey for the study area is provided as below:

M/S. GACL IN JV




Population and its distribution: There are 27 villages, with a total population of 27,059 persons and 5,766

households out of which within 3 Km there is a population of 5,573 persons in 5 villages;

Sex Ratio: 924 females per 1,000 males;

Literacy Level: male literacy is 79.3 % and female literacy is 64.3 % of total population;

Educational Facilities: There is presence of Anganwadi & Primary schools in all villages in study area. For

attaining the higher education like High School, ITI, Diploma or Engineering, facilities are available from

Bharuch;

Drinking water: The water connectivity is provided by the GIDC. At few habitation of the study area the

existing companies provide drinking water through tanker or giving tap connection water from their

companies;

Power supply is available in the villages.

Major issues in the communities are inadequate supply of drinking water, sanitation, unemployment for land

losers & poor infrastructure.

1.3 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES

1.3.1 Air Environment

Dispersion modelling (using “AERMOD” modelling software) was carried out for point and line sources. This

indicates:

Maximum 24 hourly average GLC’s for PM10 (20.7 µg/m3), SO2 (5.38 µg/m3), NOx (5.40 µg/m3), HCl (0.40

µg/m3), Cl2 (0.05 µg/m3) are within 250 m to 750 m from the proposed site;

Maximum 8 hourly average GLC’s for HC (0.025 µg/m3) & CO (2.14 µg/m3) are within 250 m to 500 m

from the proposed site;

Average incremental GLC’s at all villages will continue to be well within specified norms of CPCB for

ambient air quality.

Mitigation Measures for Air Quality Impacts:

Lime dosing will be done in the CFBC Boilers to meet the SO2 emission standards;

Adequate height of at least 80 m will be provided as per the statutory requirements to flue gas stacks

attached to boilers. APC like ESPs will be installed to meet PM emission standards;

Well-designed APCM like scrubbers (DM water & Caustic) will be provided as per the applicability to control

emissions HCl, Cl2, NOx, CO, C2H4Cl2, TOC, from process vents/stacks;

Dioxin emission will be prevented by maintaining proper combustion temperature;

Online sensors for PM, SO2 & NOx shall be provided with flue gas stack attached to boilers;

Online sensors for HCl & Cl2 shall be provided with stack attached to Hypo plant;

Plant load will be maintained to reduce the air emissions;

Effective water spraying will be done on the access roads to control re-entrained dust during dry season (if

required);

Proper operating procedures will be followed during start-up and shutdown;

Proper PPE like dust masks will be provided to workers and its use ensured;

Regular Work place monitoring will be done.

M/S. GACL IN JV




1.3.2 Incremental Traffic

From the proposed facility, approximately on daily basis, during peak hour, additional 132 PCU’s & 49 PCU’s

will be merging into the existing traffic of SH-6. The incremental traffic will lead to maximum PCU of 1,917

(Dahej to Bharuch) & 1,805 (Bharuch to Dahej). As per IRC, carrying capacity of this approach road is 3,600

PCU. Thus, the road is capable of carrying the excess traffic from the proposed project.

To ensure smooth traffic movement in the plant, proper in and out movement will be ensured. PUC certified

vehicles, covered with tarpaulins, will be used.

1.3.3 Noise Environment

Sound Pressure Levels (SPL) were predicted from the proposed project activities using “SoundPlan” Modelling

software. SPL predicted at receivers varies from 27.8 (dB) to 45.9 (dB). Logarithmic incremental of these levels

in baseline monitored data shows variation from 55.1 (dB) to 61.3 (dB) during day time and 44.9 (dB) to 57.3

(dB) during night time. Beyond 250 m from the project boundary, increase in noise level is negligible.

Passive and active controls such as noise barriers or acoustic enclosure will be provided in DG sets. Use of

suitable PPE (ear muffs or ear plugs) will be ensured. Thick green belt will be developed in the periphery of the

facility.

1.3.4 Water Environment

No withdrawal of groundwater is proposed in the project. Hence, surface and ground water will not be

impacted.

Following mitigation measures will be implemented to minimize the impact on the water environment:

During construction phase, sewage will be disposed into soak pit and septic tank. Regular cleaning will be

carried out.

There will be separate process and storm water drains.

Properly designed effluent drains with side barriers will be provided & inflow will be diverted to individual

ETP for necessary treatment to achieve Marine discharge norms.

Maximum recycle and reuse will be done to reduce the fresh water consumption.

Leakage of water at various source will be avoided.

Process, chemical fuel storage and handling area will have proper bunds and dyke walls so that

contaminated run-off cannot meet the storm-water line.

Rainwater harvesting will be done only in the admin building and from roof top of control rooms.

Domestic waste water will be treated in STP and treated water will be used for gardening purpose.

Use of drip irrigation system for greenbelt development which will reduce the overall water demand

Proper O&M of effluent treatment plants will be done to ensure meeting specified standards

During the heavy rainfall, water through internal storm water drains will meet nearest storm water drain made

by GIDC, leading to Estuary which is approximately 2.8 Km in S direction from the project site.

1.3.5 Land Environment

Based on mutually agreed terms and conditions, land was acquired from various land owners by GIDC. Plot

was allotted to GACL in year 2009 by GIDC. Change in the land use, currently from barren (scrub land) to

industrial use is envisaged.

Following mitigation measures will be implemented to minimize the impact on the land environment:

M/S. GACL IN JV




Storage areas for hazardous waste, fuel & raw material will be stored on impervious/RCC floor to prevent

leachate penetration;

Generated hazardous wastes during project operation will be transported to an authorized TSDF operator

and incineration;

Secured Landfill Facility will be provided to store Brine sludge within plant premises.

1.3.6 Ecological & Biological Environment

Removal of common site specific floral species from barren land of project site will not have significant or

permanent impact on the habitat structure of associated faunal diversity.

As the emissions from the plant are regulated and minimal with respect to the specified norms, and with a very

healthy greenbelt will be developed at the site in the form of several species, it then follows that the biological

environment will be protected.

Every year survival rate of the plantation within project site as well as other plantation carried out in the LIZ

area will be monitored. Conservation plan will be prepared to enhance the population status of this Schedule

species as well as overall improvement of biodiversity which will be implemented in consultation of local forest

department.

Greenbelt Development

Within the project site, greenbelt will be developed in 2,51,000 m2 (33% of total plot area). Considering 16 m2

(4x4) for one tree, project area will have plantation of 15,700 plants of suggested species. Plantation will be

carried out around periphery, near / around built-up areas and along internal roads of the project area.

Additional plantation for green belt development will be carried out in the various places (around nearby 5

water bodies, in school and temple premises) of LIZ to improve habitat status of the project area.

Greenbelt Maintenance

Plantations will be managed by regular watering, soil enrichment work, applying manure, weeding and provide

proper protection. Replacement of sapling (replanting) will be done whenever mortality occurs in the plantation

during the growth stage. After care for a period of minimum five years will be done till the saplings attain

matured tree stage will be done. Any damage to the developed greenbelt due to any natural or unforeseen

activities will be attended by redeveloping and maintained it.

1.3.7 Socio-Economic Environment

While assessing the socio-economic and sociological impact including health impacts to surrounding population,

the upcoming project will bring job opportunities for the local people.

1.4 Environmental Monitoring Program

Expenditure to be incurred by GACL on environmental monitoring and management shall include capital cost of

~ INR 50.85 Crore and ~ INR 2.14 Crore recurring cost (annually). Once, Environmental Clearance is obtained

and plant is in operation phase, various environmental parameters as tabulated in Table 1-8 will be

monitored.

1.5.1 Risk & Hazards

During operation of the proposed caustic chlorine, synthetic organic units & power plant, following activities

can pose hazards and risk to human and surrounding environment:

Storage of Chlorine, Methanol, Toluene & Epichlorohydrin;

Pipeline transfer of Chlorine & Methane gas;

Loading and unloading hazardous waste - mechanical movements;

Contact with hazardous chemicals;

Storage of Incinerable Waste.

On the basis of chemical properties like flash point, phase of chemical, operating conditions and total inventory

etc of the above mentioned chemicals, the study have been conducted to carry out consequence analysis.

M/S. GACL IN JV




Major failures selected for the analysis are 10 mm & 25mm leak as maximum credible scenario and

catastrophic rupture as worst case.

The results of analysis are as follows:

In case of Methanol, Toluene, & Epichlorohydrin storage tanks, the effect of pool (dyke) fire at radiation level

37.5 kW/m2 is not going out of the plant boundary.

For Chlorine tanks & pipeline, the toxic dispersion at 10 ppm slightly coming out of the plant boundary
