EIA (EIA)

Environmental Impact Assessment (EIA) is the systematic, structured study of a proposed project's likely environmental, social, and ecological effects, required under India's EIA Notification 2006 (and amendments) for any project falling within its Schedule I. The EIA process is the principal precautionary mechanism in Indian environmental law — it forces project promoters to identify, quantify, and mitigate adverse impacts before construction begins, rather than retrofitting controls after damage has occurred. An EIA-bearing project cannot proceed without Environmental Clearance (EC) issued by MoEFCC (Category A) or SEIAA (Category B).

The EIA process unfolds in four stages:

• Stage 1 — Screening determines whether full EIA, limited EIA, or no EIA is required, based on project type and capacity
• Stage 2 — Scoping involves the EAC (central) or SEAC (state) issuing Terms of Reference specifying what the EIA report must cover
• Stage 3 — Public Consultation requires a public hearing in the project district, plus written submissions from affected communities, NGOs, and experts
• Stage 4 — Appraisal sees the EAC/SEAC scrutinise the final EIA report, including public hearing outcomes, and recommend approval, refusal, or conditional approval to MoEFCC/SEIAA

A typical EIA report covers:

• Baseline data — one full season of air, water, soil, noise, ecology, and socioeconomic monitoring
• Impact prediction — modelling of air dispersion, water quality, traffic, ecology, cumulative impact
• Environmental Management Plan (EMP) — mitigation measures, monitoring schedule, budget allocation
• Risk assessment — disaster management plan, emergency response, worst-case scenarios

Preparing an EIA report typically takes 12–18 months and costs ₹25 lakh–1.5 crore depending on project size and location sensitivity. EIA consultancies must be NABET-accredited. For Indian CBG and recycling entrepreneurs, the practical question at project initiation is whether the proposed capacity falls under Schedule I — most CBG plants under 12,000 m³/day and most plastic mechanical recyclers under 50 TPD remain below EIA thresholds, while large-scale plastic chemical recycling, tyre pyrolysis above 25 TPD, and integrated e-waste smelting are typically Category B and require full EIA. Mis-classifying a project as below-threshold to avoid EIA is a serious risk — discovery during operation typically leads to closure orders and prosecution under Section 19 of the EPA.
