SEIAA (SEIAA)

State Environment Impact Assessment Authority (SEIAA) is the state-level statutory body constituted under the EIA Notification 2006 (issued under the Environment Protection Act 1986) that grants Environmental Clearance (EC) for Category B industrial projects. Each Indian state has its own SEIAA, typically a three-member body comprising a chairperson, two members appointed by MoEFCC on the recommendation of the state government, and supported by a state-level secretariat. SEIAA decisions are based on technical appraisal by the State Expert Appraisal Committee (SEAC), which provides subject-matter recommendation for or against EC.

SEIAA jurisdiction covers Category B projects under the EIA Notification — the medium-impact tier between Category A (handled centrally by MoEFCC + EAC) and projects requiring no EC at all. For CBG and recycling sectors, common Category B triggers include: MSW-based WtE plants above 25 TPD, biomethanation plants with installed capacity 1–5 MW, plastic pyrolysis units handling 10–50 TPD, tyre pyrolysis units handling 10–50 TPD, and recycling facilities with capacity-specific thresholds. Within Category B, projects above a sub-threshold (B1) require full EIA studies with public consultation; smaller B2 projects qualify for streamlined assessment without public consultation.

The SEIAA appraisal process typically runs 6–12 months from ToR application to EC grant. Project developers file initial Form 1 application with project category determination, attend pre-EIA scoping meeting with SEAC, receive Terms of Reference specifying study scope, conduct one season of baseline monitoring (3–4 months for air, water, soil, noise, biodiversity), prepare draft EIA report, undergo public hearing for B1 projects, submit final EIA with public hearing minutes incorporated, and receive SEIAA decision. Cost runs ₹15–40 lakh including consultant fees, baseline monitoring, and consultation logistics. The state-level processing — versus central MoEFCC for Category A — provides faster response and better local context, but also creates state-by-state variation in technical rigour and consistency that experienced consultants navigate carefully.

• State-level EC granting body for Category B industrial projects under EIA Notification 2006.
• Three-member body supported by State Expert Appraisal Committee (SEAC) for technical review.
• CBG/WtE/pyrolysis thresholds (10–50 TPD typical) trigger Category B and SEIAA jurisdiction.
• Process 6–12 months, cost ₹15–40 lakh; B1 requires EIA + public hearing, B2 streamlined.
