The baseline data includes the socio economic status of the area. The data about the

human settlements in and around the project site, health status of the community, existing

infrastructure facilities for social welfare, job opportunities, safety and security of the

workers and the surrounding population. The positive impact of the proposed project and

the socio economic status in the buffer zone is reported.

4. ENVIRONMENTAL IMPACTS & MITIGATION MEASURES 4.1 Air Environment

The impact on air environment depends on the raw materials of member industries. SO2

& NOX are anticipated during the usage of DG sets and boilers. The vehicles used for

transportation of raw materials will cause air pollution.

Mitigation Measures

Use of low Sulphur diesel will minimize the emission from diesel generators.

Development of green belt will reduce the level of particulate matter.

The emission standards fixed by government authorities will be followed.

Vehicles will be maintained properly.

Green belt development

Pollution abatement via green belt development is one of the vital components for any

Industrial activity. The main objectives of green belt development plan in any area are

1. Aesthetic Enhancement.

2. Reduction of impacts of air pollution and dust.

3. Arrest soil erosion

4. Climatic amelioration

4.2 Noise Environment

During operation phase, noise pollution will be aroused due to DG sets, vehicular

movements and machineries in industries. There will not be much noise during Operation

phase.

Mitigation Measures

Proper acoustic measures will be provided to reduce the noise generated by DG sets

and isolation of DG will reduce the noise at receiver’s end.

Green belt development will also reduce noise level.

8 July 2018

Executive Summary 4.3 Water Environment

During the operation phase water will be sourced from Hemavathi River. The effluent which

is supposed to be generated may cause severe problems to the environment when

compared with the wastewater generated by domestic activities. The members industries

are responsible for treating effluent from industries.

Mitigation Measures

The waste water generated by domestic activities will be treated in STP of capacity 2.0

MLD. Industrial effluents having different properties will be treated in ETP of respective

industry. KIADB will mandate member industries to adopt Zero Liquid Discharge System

as well as Rain Water Harvesting structures.

Storm water drains will be provided to collect water during rains. It would be sized

adequately to prevent flooding of the site. It is proposed to have rain water harvesting

structures for recharge of roof top rain water and rainwater of paved surface at respective

buildings. The storm water drains will be acting as recharge trench and intermittent check

dams will be provided in the storm water drains to infiltrate maximum amount of water

into the ground.

4.4 Soil Environment

Dumping of municipal and industrial waste on the land will affect the soil quality. Poor

Garbage management will lead to unsanitary conditions including vermin, odor and fly

infestation. The spillage of waste oil from DG sets will also affect the land.

Mitigation Measures

• The waste generated will be treated and disposed properly.

• Toxic waste from industries will not be disposed on land without treating it in a

proper manner.

• Generation of waste will be minimized at the source.
