- Clearance Acceleration: Average environmental clearance time reduced from 600+ days to 70 days via the single-window PARIVESH Portal.
- Decentralized Tiers: Projects are divided into Category A (National appraisal by EAC) and Category B (State appraisal by SEAC).
- Public Hearing Window: Mandates a minimum of 30 days for local community feedback.

1. THE FOUR STAGES OF THE EIA PROCESS (2006 NOTIFICATION)

Stage 1: Screening: Applies to Category B projects to determine if they need a detailed EIA (categorized as B1, requiring EIA) or are exempt (B2). Category A projects require a mandatory EIA.
Stage 2: Scoping: Formulating the Terms of Reference (ToR) by the Expert Appraisal Committee (EAC). Defines the boundaries of the environmental study and baseline data requirements.
Stage 3: Public Consultation: Accessing local community inputs through a public hearing (conducted by the State Pollution Control Board) and receiving written responses within a mandatory 30-day window.
Stage 4: Appraisal: Final technical review of the EIA report, public hearing minutes, and mitigation plans by the EAC or SEAC to recommend clearance or rejection.

Conflict of Interest: Project proponents hire and finance the EIA consultants directly, incentivizing consultants to underreport ecological risks and copy-paste reports.
Lack of Cumulative & Strategic EIA: Appraisals are conducted project-by-project. This ignores the cumulative impact on the carrying capacity of an entire ecological zone (e.g., the Himalayas or industrial clusters).
Inadequate Post-Clearance Monitoring: Weak enforcement of Environmental Management Plans (EMPs) due to under-staffed SPCBs and lack of independent environmental regulatory audits.

Proposed draft notification revisions have triggered significant debates:

Ex-Post Facto Clearance: Allowing projects to start operations without prior clearance and apply for retroactive validation. The Supreme Court has repeatedly struck this down as violating the Precautionary Principle.
Strategic Exemptions: Exempting national security border road projects (within 100 km of international borders), inland waterways, and coal mining expansions from public consultations.
Reduction of Public Window: Attempting to reduce the public feedback notice window from 30 days to 20 days, which limits participation by tribal and rural communities.
