Exemptions from Environmental Clearances | 23 Jan 2020
Why in News
The Environment Ministry has issued a notification to exempt oil and gas firms from seeking environmental clearance for on-shore and offshore drilling explorations.
- Onshore drilling refers to drilling deep holes under the earth's surface whereas offshore drilling relates to drilling underneath the seabed.
- These drilling methods are used in order to extract natural resources – usually oil and gas – from the earth.
Key Points
- Demotion of Exploratory Projects: The notification has demoted exploratory projects to the category of ‘B2’ in the process of Environment Impact Assessment (EIA).
- Category B projects are appraised at the state level and they are classified into two types.
- Category B1 projects (Mandatorily requires EIA).
- Category B2 projects (Do not require EIA).
- Category B projects are appraised at the state level and they are classified into two types.
- Exceptions : The development of an offshore or onshore drilling site as a hydrocarbon block will continue to be classified as a “category A”.
- Decentralisation: The exemption is part of a process of ‘decentralisation’ by the Centre as it seeks to delegate more regulatory actions to State and local units.
Background
- Previously, exploratory surveys required the highest level of environmental scrutiny and were classified under category ‘A’ projects.
- The category ‘A’ project needs to prepare an EIA plan and is scrutinised by a Centrally constituted committee of experts.
- The project would also be subject to a public hearing involving the locals of the proposed project site.
- Though, Public hearings, for category ‘A’ projects, are generally exempted if they are offshore projects
Environmental Concerns
- The exploratory drilling process is an ecologically-intensive exercise that involves digging multiple wells and conducting seismic surveys offshore. Thus exemptions may cause loss of biodiversity.
- The offshore drilling operations can possibly affect fish, lead to a build-up of heavy water contaminants, disorient whales and sea life.
- The risk of oil spills threatens the coastal as well as terrestrial ecosystems.
