Yes Risk Analysis was carried out as a part of EIA study. Risk mitigation measures are accordingly suggested.

8.2 From any other causes No -

8.3 Could the project be affected by natural disasters causing environmental damage (e.g. floods, earthquakes, landslides, cloudburst, etc.)?

Yes The project site is falling in seismic Zone V (Very high risk earthquakes). Based on the Probabilistic Seismic Hazard Assessment (PSHA) carried out for the project site, recommendations were made for the strong ground motion at the site in terms of design response spectra for various return periods along with appropriate strong motion time histories.

The Peak Ground Acceleration (PGA) values for the Maximum Considered Earthquake (MCE) and Design Basis Earthquake (DBE) conditions are estimated as 0.34 g and 0.09 g, respectively, for both horizontal components from PSHA.

However, considering that the project site lies in Zone V of the IS: 1893 (Part-I 2002) the PGA may be adopted as 0.36 g and 0.18 g for MCE and DBE conditions, respectively. A factor of 2/3 may be considered for vertical component.

Necessary precautionary measures would be built-in / implemented.

9. Factors which should be considered (such as consequential development) which could lead to environmental effects or the potential for cumulative impacts with other existing or planned activities in the locality

S. No.


Yes / No

Details thereof (with approximate quantities / rates, wherever possible) with source

of information data

9.1 Lead to development of supporting utilities, ancillary development or development stimulated by the project which could have impact on the environment e.g.:

1. Supporting infrastructure (roads, power supply, waste or wastewater treatment, etc.)

2. Housing development

3. Extractive industries

4. Supply industries

5. Other

Yes

Induced development due to the proposed project in the region, which will create better infrastructure and will attract migration of people

Necessary supportive utilities, infrastructure, housing etc to cater the requirements of the project would be developed as a part of the project

9.2 Lead to after-use of the site, which could have an impact on the environment

No The proposed project would be a permanent establishment

9.3 Set a precedent for later developments

Yes The region has potential for industrial investments in the form of power plants, industries, seaport, SEZs etc

9.4 Have cumulative effects due to proximity to other existing or planned projects with similar effects

Yes 6x660 (3960) MW Coal Based Thermal Power Plant will be located in the proposed Multi Product SEZ. The possible cumulative effects on the study area are considered and addressed adequately in the EIA.
