S.No

Information/Checklist confirmation

Yes/No

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

7.1

From handling, storage, use or spillage of hazardous materials

Yes

There are no hazardous material of significant quantity that will be handled or stored on the MODU other than HSD. There can be potential spillages during transfer of HSD from supply vessel to MODU also called as bunkering. Emergency in the form of well blow-out could occur if the well gets out of control and all barriers are lost. In such a case there could be uncontrolled release of hydrocarbons that can cause oil spill and marine pollution.

7.2

From discharge of sewage or other effluents to water or the land (expected mode and place of discharge)

The sewage and wash water will be discharged only after treatment and thus contamination is not anticipated.

7.3

By deposition of pollutants emitted to air into the land or into water

Emissions from diesel engines will be under permissible limit and will get dispersed rapidly.

7.4

From any other sources

None

7.5

Is there a risk of long term build up of pollutants in the environment from these sources?

Exploratory drilling is temporary and impacts are transient in nature. However, mitigation measures will be in place to avoid any risk of long term build-up of pollutants in the environment.

8	Risk of accidents during construction or operation of the Project, which could affect human health or the environment

S.No

Information/Checklist confirmation

Yes/No

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

8.1

From explosions, spillages, fires etc from storage, handling, use or production of hazardous substances

Yes

Potential risks include well blowout due to abnormal reservoir pressure encountered during drilling of a well which may result in explosion, fire and spillage. To minimize such risk, blowout preventers and other mitigation measures will be in place. Other risks that will be assessed as part of Risk Assessment studies are those from fire in diesel storage, collisions and structural failures.

8.2

From any other causes

Yes

Risk of physical injuries during exploration activities. The MODU will have safety systems to mitigate the above risk

8.3

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

Yes

Natural disasters like cyclones and storm pose potential risk. MODU will have early warning systems and Emergency Response Plan will be in place Drilling will be carried out during fair weather.

The offshore exploratory drilling is a temporary project of short duration. In the event of discovery of hydrocarbon field however there could be commercial exploitation.

9.2

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

Yes

The after-use of the drilled wells is possibly only in case of a successful hydrocarbon discovery. The fields discovered will then be developed for hydrocarbon production. The impacts from developmental activities would depend on the extraction technology adopted and hydrocarbon field development plan. In case of a dry well, the well will be plugged and sealed at the sea bed as per international practice of hydrocarbon drilling well closure and abandonment.

Yes

A precedent may be set only in case of successful (commercially viable) hydrocarbon discovery.

9.4

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