Most environmental clearances in India are granted not by the Union ministry but by State Environment Impact Assessment Authorities. Under the EIA Notification, 2006, the central government constitutes a SEIAA for each state and Union territory, along with a State Expert Appraisal Committee. The SEAC appraises Category B projects and recommends grant or rejection, and the SEIAA decides. Category B covers many building and construction projects, townships, mining of minor minerals, and industrial projects below the thresholds for Category A.
For builders and smaller industries, the SEIAA is often the most important environmental regulator. Delays in SEAC meetings, queries on documents, and conditions imposed on EC can make or break project timelines. Where a state's SEIAA is not functioning, for example because its term has expired, the central ministry may appraise Category B projects in the interim. This page explains how to deal with SEIAAs and SEACs, the process and timelines, common issues, and how to challenge decisions.
हिंदी में सारांश
ज़्यादातर पर्यावरण मंज़ूरियाँ राज्य स्तरीय पर्यावरण प्रभाव आकलन प्राधिकरण (SEIAA) देता है। EIA अधिसूचना, 2006 के तहत हर राज्य में SEIAA और राज्य विशेषज्ञ मूल्यांकन समिति (SEAC) होती है। SEAC कैटेगरी B प्रोजेक्ट (बिल्डिंग, टाउनशिप, लघु खनिज खनन, छोटे उद्योग) का मूल्यांकन कर सिफ़ारिश करती है और SEIAA निर्णय लेता है। B1 प्रोजेक्ट में EIA और आम तौर पर जन सुनवाई ज़रूरी है, B2 में नहीं।
Is this your situation?
- Your building project has a built-up area above 20,000 square metres
- You are developing a township or area development project
- You need EC for mining of minor minerals
- Your industrial project falls in Category B
- Your application is pending before the SEAC for months
- The SEIAA imposed conditions you cannot meet
- Your EC application was rejected
SEIAA and SEAC at a glance
Constitution
SEIAA and SEAC constituted by the central government for each state and UT.
Category B projects
Projects below Category A thresholds listed in the EIA schedule.
B1 and B2
B1 projects need EIA and usually a public hearing; B2 projects are appraised on Form 1 and other documents.
Appraisal
SEAC appraises and recommends; SEIAA decides.
PARIVESH
Applications are made and tracked online.
Challenge
EC decisions can be appealed to the NGT.
How the process works
The proponent submits the application on PARIVESH with Form 1 and supporting documents. For B projects, the SEAC first screens the project to decide whether it is B1 or B2. For B1 projects, the SEAC issues terms of reference for the EIA study, standard terms of reference are often applied, and after the EIA and public hearing the final report is appraised. For B2 projects, appraisal is based on Form 1, the conceptual plan for building projects, and other documents, without a full EIA or public hearing.
At the appraisal meeting, the proponent or its consultant presents the project, and the SEAC members ask questions. The SEAC may recommend grant with conditions, seek more information, or recommend rejection. The SEIAA then decides at its meeting. The notification sets time limits for these stages, generally 60 days for appraisal after receipt of complete documents and 45 days for the decision after recommendation, though delays are common.
Building projects before the SEIAA
Building and township projects form the largest share of SEIAA work. Common issues raised by SEACs include the calculation of built-up area including basements, phasing of projects, groundwater use during construction and operation, sewage treatment and reuse, rainwater harvesting, solid waste and C&D waste plans, traffic impact, green cover, and energy efficiency. Projects near protected areas, forests, water bodies or in critically polluted areas attract additional scrutiny.
Since the Supreme Court's August 2025 decision striking down the January 2025 exemption, industrial sheds, schools, colleges and hostels above the threshold again need EC, and SEIAAs have seen more applications from institutions. Since the July 2026 decision in Vanashakti, post-facto applications under the 2021 office memorandum are no longer available, making prior EC essential. See EC for building projects.
Delays and non-functional authorities
SEAC and SEIAA meetings depend on members being appointed and available. When terms expire and new members are not appointed, applications pile up. The EIA Notification provides that where a SEIAA or SEAC is not in place, Category B projects are to be appraised at the central level. In practice, proponents should track the status of their state's authority, follow up in writing, and where the authority is not functioning, check whether their application can be taken up centrally.
Within a functioning authority, delays often arise from incomplete responses to queries. Respond fully and promptly, and keep the consultant's presentation focused on the SEAC's concerns. Where a decision is unreasonably delayed beyond the notification's timelines, a written representation followed by legal remedies may be considered.
How to deal with the SEIAA
Confirm category
B1 or B2, and whether the project is in the schedule at all.
Prepare complete documents
Form 1, plans, studies and other approvals.
Apply on PARIVESH
And track the status.
Prepare for the SEAC meeting
Presentation and answers to likely questions.
Respond to queries promptly
Fully and with documents.
Comply with conditions
And report compliance every six months.
Conditions and challenges
EC from the SEIAA comes with specific and general conditions. Some conditions are standard; others are project-specific. If a condition is unworkable or based on a misunderstanding, the proponent can apply for amendment through PARIVESH with reasons. Where the SEIAA rejects the application, or the EC is challenged by third parties, an appeal lies to the National Green Tribunal under Section 16 of the NGT Act within 30 days, extendable by up to 60 days. Residents and others aggrieved by an EC have also used this route. See EC compliance report.

How we work
We are a litigation and advisory practice led by Advocate BK Singh, with offices in Dwarka (New Delhi) and Vaishali (Ghaziabad). This is what you can expect:
- Category confirmed early: B1, B2 or outside the schedule.
- SEAC queries answered: fully and quickly.
- Delays escalated: with representations and remedies.
- Conditions reviewed: amendment where unworkable.
- Written fee terms: agreed stage by stage, never linked to the outcome.
Mistakes we see before the SEIAA
- Calculating built-up area without basements
- Splitting a project into phases to avoid EC
- Starting work while the application is pending
- Slow, partial responses to SEAC queries
- Ignoring EC conditions after grant
A college campus after the 2025 ruling
Here's a made-up example. A Ghaziabad college had planned a new block of 24,000 square metres relying on the January 2025 exemption. After the Supreme Court struck down the exemption, it had to apply for EC.
We helped it apply on PARIVESH as a B2 project with complete documents. The SEAC raised queries on groundwater and STP capacity, which were answered promptly, and the SEIAA granted EC with conditions.
A mining lease's EC
Here's a second made-up example. A minor mineral lease holder in Haryana had its EC application pending for months because the SEAC's term had expired.
We wrote to the authorities, tracked the reconstitution of the committee, and prepared the proponent for the first meeting of the new SEAC. The application was taken up and recommended at that meeting.
