What is ToR?
Terms of Reference (ToR) is the formal scoping document issued by the Expert Appraisal Committee (EAC) for Category A projects or the State Expert Appraisal Committee (SEAC) for Category B projects under India's EIA framework, specifying exactly what an Environmental Impact Assessment report must cover for that particular project. ToR is issued after the pre-scoping meeting where the project proponent presents project parameters, site characteristics, and likely impacts; the committee then prescribes the specific studies, monitoring, modelling, and disclosure required in the EIA report.
A standard ToR for an Indian CBG, recycling, or pyrolysis project typically runs 4–8 pages and covers: project description (capacity, technology, products, schedule), baseline environmental data requirements (one full season of ambient air, surface and ground water, soil, noise, biodiversity, demography), impact assessment scope (operational and construction-phase impacts on air, water, soil, noise, ecology, socio-economic), modelling requirements (AERMOD for stack dispersion, MIKE21 for water bodies if relevant), pollution-control system design and performance specifications, hazardous and solid waste management plan, occupational health and safety plan, disaster management plan, Corporate Environmental Responsibility commitments, and any site-specific concerns (proximity to ecologically sensitive area, archaeological monuments, schools, water bodies).
ToR drives EIA cost, timeline, and quality. A well-defined ToR with focused scope leads to a 6–9 month EIA study costing ₹15–30 lakh and clean technical appraisal. A vague or over-broad ToR adds 3–9 months and ₹10–25 lakh of additional study cost while risking EAC/SEAC questions during appraisal. Mature project developers proactively suggest ToR content during the scoping meeting based on prior EIA precedents for similar projects, helping the committee converge on a defensible and proportionate scope. ToR validity is typically 4 years for the project — meaning baseline studies and EIA reports must be completed and submitted within this window or face re-scoping. Familiarity with EAC/SEAC sector-specific ToR templates published on PARIVESH portal is essential preparation for any project developer.
- Scoping document specifying EIA study scope, issued by EAC (Category A) or SEAC (Category B).
- Covers baseline data, impact assessment, modelling, pollution-control specs, CER commitments.
- Drives EIA cost (₹15–30 lakh good, ₹25–55 lakh broad) and timeline (6–9 vs 12–18 months).
- Validity 4 years; sector-specific templates on PARIVESH portal guide proposal preparation.
