The document outlines important amendments made to India's Environmental Impact Assessment (EIA) regulations over time. Key amendments include: - 1994 made it mandatory for projects to obtain an Environmental Clearance certificate and established the EIA agency. - 1997 introduced public hearings for projects. 2003 required more studies and inspections for assessments. - 2006 regulations divided projects into two categories requiring clearance from central or state governments. It also decentralized some processes. - The new 2020 draft is disputed as it allows post-facto approval, reduces time for public consultation, relaxes monitoring requirements, and could allow projects up to 150,000 sq meters to avoid scrutiny.
