Recent Advances in EIA Governance: Streamlining Environmental Regulations in India

India’s Environmental Impact Assessment (EIA) framework has undergone a remarkable transformation over the past three decades. What started as a basic administrative requirement in the early 1990s has evolved into a multi-layered regulatory system with digital infrastructure, decentralised decision-making, and structured public participation. Understanding how EIA governance has changed – and continues to change – is essential for anyone involved in environmental planning, project development, or sustainability policy in India.

How EIA governance began in India 🔗

The roots of EIA in India go back to the late 1970s, when the government began requiring environmental appraisals for large infrastructure projects. However, these early requirements were purely administrative – there was no legislative backing to enforce them. Projects could sidestep the process with relative ease, and there was no standardised framework for assessing environmental impacts.

That changed in 1994 when the Ministry of Environment and Forests (MoEF) issued the EIA Notification under the Environment (Protection) Act, 1986. This was India’s first formal legal instrument specifically governing EIA. The 1994 Notification made it compulsory for all projects listed under Schedule I – including nuclear power plants, river valley projects, ports, airports, petroleum refineries, and major mining operations – to obtain environmental clearance from the Central Government before commencing work.

The notification also specified that project proponents must submit an EIA report to the Impact Assessment Agency, which would then consult a multi-disciplinary expert committee before granting or denying clearance. While this was a significant step forward, the 1994 framework had notable gaps: there was no public hearing mechanism, the categorisation of projects was based on investment size rather than environmental impact, and all clearance authority rested with the central government alone.

Key amendments that shaped EIA governance (1997-2005) 🔗

Between 1994 and 2006, the EIA Notification was amended roughly 12 times. Some of these amendments strengthened the process, while others drew criticism for diluting it. Here are the most consequential changes.

The 1997 amendment: introducing public hearing 🔗

The April 1997 amendment was a watershed moment. It introduced the concept of Environmental Public Hearing (EPH) into India’s clearance process for the first time. State Pollution Control Boards (SPCBs) were given the responsibility to organise public hearings, gather the views of affected communities, and ensure fair representation. The amendment required that notices be published in at least two newspapers – one in the local language – and that the public be given 30 days to submit their views. This amendment also decentralised certain power plant clearances, placing some categories of thermal plants under the jurisdiction of SPCBs rather than the central government.

The 2000 amendments: exemptions for small-scale projects 🔗

The amendments in January and December 2000 exempted certain categories from the EIA requirement. Small-scale industrial units with investment below Rs. 1 crore and defence-related road construction in border areas no longer needed to go through the clearance process. By this point, the scope of EIA had expanded to cover approximately 30 types of activities.

The 2002 amendment: investment-based exemptions 🔗

The June 2002 amendment is widely considered one of the more controversial changes to the 1994 notification. It exempted projects with investment below Rs. 100 crore (for new projects) and Rs. 50 crore (for expansion projects) from the environmental clearance process entirely. Pipeline and highway projects were also exempted from the EIA report requirement, though they still needed public hearings in each district they passed through. Critics argued this amendment allowed many potentially harmful projects to bypass environmental scrutiny simply because of their investment size.

The 2003 amendments: location sensitivity and site clearance 🔗

Multiple amendments in 2003 brought important changes. The February 2003 amendment introduced location sensitivity into the clearance process – projects situated within 15 km of reserved forests, national parks, sanctuaries, or biosphere reserves, or located in critically polluted areas, now required central government clearance regardless of their size. The September 2003 amendment made site clearance mandatory for greenfield airports, petrochemical complexes, and refineries, and also removed the public hearing requirement for offshore exploration activities beyond 10 km from sensitive areas and habitations.

The 2004-2005 amendments 🔗

The 2004 amendment brought construction projects and industrial estates within the EIA framework. In July 2005, a provision was introduced allowing projects to obtain a temporary working permit for up to two years even without an environmental clearance – a move that drew significant criticism from civil society and environmental groups.

The 2006 notification: a complete overhaul 🔗

By the mid-2000s, it was clear that the 1994 notification and its patchwork of amendments were not adequately serving India’s environmental governance needs. The MoEF published a draft notification in September 2005, invited public comments for a year, and in September 2006, issued an entirely new EIA Notification that superseded the 1994 version.

Category-based project classification 🔗

One of the most significant changes was the way projects were classified. The 2006 Notification moved away from investment-based categorisation and instead divided projects into Category A and Category B based on their size, capacity, and potential environmental impact. Category A projects – those with larger spatial footprint or greater potential harm – continued to require clearance from the central government (MoEF). Category B projects were placed under the jurisdiction of newly created State-Level Environment Impact Assessment Authorities (SEIAAs) and State-Level Expert Appraisal Committees (SEACs).

Category B was further subdivided into B1 (requiring a full EIA report) and B2 (exempted from the EIA report requirement). This tiered system allowed for a more proportional assessment process – smaller, lower-impact projects faced less regulatory burden, while major projects continued to undergo rigorous scrutiny.

The Terms of Reference (ToR) requirement 🔗

The 2006 Notification also formalised the scoping stage of the EIA process through the introduction of Terms of Reference (ToR). For Category A projects, the central-level Expert Appraisal Committee (EAC) would issue the ToR. For B1 projects, the SEAC would do the same. The ToR had to be conveyed to the applicant within 60 days of application submission on the portal. If this deadline was missed, the ToR proposed by the applicant would be deemed final – a provision designed to prevent indefinite delays in the clearance process.

A structured four-stage process 🔗

The 2006 Notification established a clear four-stage clearance process: screening, scoping, public consultation, and appraisal. Each stage had defined timelines and responsibilities. Public consultation now had two components – a public hearing at or near the project site, conducted by the SPCB within 45 days, and a mechanism for collecting written responses from stakeholders. The final appraisal had to be completed within 60 days of receiving the revised EIA report.

The overall goal was to reduce the time required for clearance. Under the old system, clearance could take anywhere from 14 to 28 months. The 2006 Notification aimed to bring this down to approximately 10 to 12 months for Category A projects.

Decentralisation of power 🔗

A defining feature of the 2006 Notification was its push toward decentralisation. By creating SEIAAs and SEACs in every state, the notification shifted a significant portion of the clearance workload away from the central government. This was both an efficiency measure and an attempt to bring decision-making closer to the communities and ecosystems affected by projects. However, critics raised concerns about whether state-level authorities would have the capacity and independence to resist political pressure from local industry interests.

Amendments to the 2006 notification 🔗

The 2006 Notification has itself seen numerous amendments over the years. The number of paragraphs in the main notification has grown from 12 to 14, new appendices have been added (from six to sixteen), and the schedule of projects has been revised multiple times. A new B2 sub-category was introduced for mining of minor minerals. In 2016, a scheme for accreditation of EIA consultants was introduced to improve the quality and credibility of EIA reports.

One notable 2016 amendment addressed building and construction projects, integrating environmental conditions with building permissions for projects between 20,000 and 1,50,000 sq. metres of built-up area. The amendment allowed environmental clearance to be issued alongside building permission through state-level building bye-laws – a move described as a step toward decentralisation and ease of doing responsible business.

More recently, in March 2025, the MoEFCC reversed a controversial exemption that had allowed excavation activities for linear infrastructure projects (roads, pipelines, transmission lines) to proceed without environmental clearance. The new amendment introduced standard operating procedures and environmental safeguards for sourcing ordinary earth for such projects – rebalancing infrastructure development with ecological protection.

Modernisation through PARIVESH 🔗

Perhaps the most transformative recent advance in EIA governance is the launch of PARIVESH – the Pro-Active and Responsive facilitation by Interactive, Virtuous and Environmental Single-window Hub. Launched in August 2018 by the Prime Minister, PARIVESH is a web-based, single-window platform for online submission and monitoring of proposals seeking Environment, Forest, Wildlife, and Coastal Regulation Zone (CRZ) clearances.

What PARIVESH does 🔗

PARIVESH provides a single registration and sign-in for all types of clearances, assigns a unique ID to each project across all clearance types, and automates the entire workflow – from application submission to agenda generation, minutes of meetings, and final approval letters. The system is designed to work at central, state, and district levels, ensuring uniformity across the country.

Key features include a GIS-based Decision Support System that allows expert committees to spatially analyse project proposals, a Know Your Approval (KYA) module that tells proponents which clearances they may need, and a Compliance Management module for submitting and tracking compliance reports including geo-tagged images. The system also sends automatic alerts via SMS and email at key stages to relevant officers and committee members, helping flag and prevent delays.

Impact on processing time and transparency 🔗

The introduction of PARIVESH has measurably improved the efficiency of environmental clearance in India. The portal has processed over 50,000 clearances since its launch. By automating agenda preparation, enforcing a first-come-first-served principle for project appraisals, and enabling real-time application tracking, the system has reduced the overall time taken for granting clearances. The platform also highlights non-compliance automatically, making it harder for conditions attached to clearances to be ignored or overlooked.

PARIVESH also represents a shift in the government’s self-described role – from being a regulator to acting more as a facilitator of responsible development. Whether this framing holds up under scrutiny is an ongoing debate among environmentalists, legal experts, and industry stakeholders.

Challenges and the road ahead 🔗

Despite significant progress, EIA governance in India continues to face challenges. The quality of EIA reports remains inconsistent, with concerns about the independence and competence of some accredited consultants. Public hearings, while institutionalised, are sometimes marred by inadequate notice periods, limited access to information in local languages, or intimidation of participants. The tension between development speed and environmental rigour remains a recurring theme in every amendment and policy discussion.

The draft EIA Notification 2020, which proposed replacing the 2006 framework, drew significant public criticism for provisions seen as weakening environmental safeguards – including reduced public consultation periods and provisions for post-facto clearances. That draft has not been finalised, and the 2006 Notification, with its ongoing amendments, remains the governing framework.

Going forward, the effectiveness of India’s EIA governance will likely depend on three factors: the continued strengthening of digital infrastructure like PARIVESH, meaningful and accessible public participation in the clearance process, and the capacity and independence of state-level appraisal bodies to make decisions based on environmental merit rather than political or economic pressure.

What do you think? Has the shift toward digital platforms like PARIVESH genuinely improved environmental governance, or has it primarily made the clearance process faster without ensuring better environmental outcomes? And with so many amendments to the 2006 Notification over nearly two decades, is it time for a completely new, ground-up EIA framework for India?
