A plain-language guide to all 12 steps of the State Environmental Quality Review Act — New York's framework for protecting the environment, one project at a time.
The State Environmental Quality Review Act (SEQR) requires New York State and local agencies to consider the environmental impacts of actions they approve, fund, or directly undertake before a decision is made. It is governed by 6 NYCRR Part 617.
Core Principle
SEQR puts environmental review upfront. Agencies must weigh environmental consequences alongside social and economic factors when making decisions.
SEQR applies whenever a state or local agency has discretionary authority — the power to approve or deny a permit, license, or other action. It also covers agency-funded projects and adopted plans or policies.

1First Question
Is the Action Subject to SEQR?
Not every project triggers SEQR. The threshold question is: does a government agency have discretionary authority over this action?
Discretionary Approval
A state or local agency can approve, deny, or impose conditions on the action. SEQR applies.
Agency-Funded or Undertaken Project
An agency directly funds or undertakes construction, programs, or resource management plans. SEQR applies.
Ministerial Actions
The agency has no discretion — approval is automatic if requirements are met. SEQR does not apply.
2Classification
Classify the Action
Once SEQR applies, the action is sorted into one of three categories. Classification determines how much environmental review is required.
EIS Likely
⚠️
Type I
Meets or exceeds thresholds in §617.4. More likely to cause significant adverse impacts. Full EAF mandatory; EIS probable.
EIS Possible
📋
Unlisted
Not on either list. Short EAF required at minimum. EIS possible depending on the significance determination.
No EIS Required
🚫
Type II
Listed in 6 NYCRR §617.5. Determined to have no significant impact. Review ends immediately.
3Paperwork
Complete the Environmental Assessment Form
The Environmental Assessment Form (EAF) is the primary tool for gathering information about a proposed action and its potential environmental impacts.
Who Fills It Out?
The project sponsor or applicant completes Part 1. The lead agency completes Parts 2 and 3.
Full EAF → Type I Actions
Comprehensive form covering all environmental areas (617.20 Appendix A). Also required for Conditioned Negative Declarations.
Short EAF → Unlisted Actions
Streamlined form for smaller projects (617.20 Appendix B). A Full EAF may substitute if the short form is insufficient.
Parts 2 & 3: Lead Agency's Responsibility
Part 2 identifies potential impacts. Part 3 evaluates significance and must provide detailed reasoning — conclusory statements are legally insufficient.
4Coordination
Coordinate Review & Select a Lead Agency
When multiple agencies have jurisdiction, they must agree on a single Lead Agency to oversee the SEQR review and take responsibility for the environmental analysis.
30-Day Rule
Involved agencies have 30 calendar days to agree on a lead agency. If no agreement, any agency or the applicant may ask the DEC Commissioner to designate one.
For Type I actions, coordinated review is always required. For Unlisted actions, agencies may choose coordinated review, uncoordinated review, or the Conditioned Negative Declaration path.
5The Key Decision
Determine Significance
The lead agency has 20 calendar days to decide whether the action may have a significant adverse impact on the environment. This decision determines everything that follows.
🟢
Negative Declaration
No significant adverse impact. Review ends. Project proceeds to normal approvals. Must be supported by detailed written reasoning — conclusory statements are legally insufficient.
🔵
Conditioned Neg. Dec.
For Unlisted actions only. Impacts reduced through imposed conditions. Requires Full EAF, coordinated review, and a 30-day public comment period.
🔴
Positive Declaration
The action may cause significant adverse impacts. A full Environmental Impact Statement is required. Triggers Steps 6 through 12.
6EIS Path Begins
Scoping: Defining What the EIS Must Address
Once a Positive Declaration is issued, scoping is the process by which the lead agency — with input from involved agencies, the applicant, and the public — identifies the specific environmental issues, alternatives, and mitigation measures the Draft EIS must analyze.
Why Scoping Matters
Scoping focuses the EIS on what truly matters, preventing the document from becoming an unfocused data dump. A well-scoped EIS saves time, reduces costs, and produces a more useful analysis.
Lead Agency Initiates Scoping
After the Positive Declaration, the lead agency prepares a draft scope or requests one from the applicant. Strongly recommended under 6 NYCRR §617.8.
Public and Agency Input
The draft scope is circulated to involved agencies and the public. A scoping meeting may be held. Anyone can comment on what the EIS should cover.
Final Scope Issued
The lead agency issues a Final Scope — the roadmap the applicant must follow when preparing the Draft EIS.
Topics Typically Scoped In
Land use, traffic, noise, air quality, water resources, wetlands, endangered species, cultural resources, socioeconomic effects, and the no-action alternative.
7The Core Document
Preparing the Draft Environmental Impact Statement
The Draft Environmental Impact Statement (DEIS) is the centerpiece of the SEQR process for significant actions. Prepared by the project applicant, it must rigorously follow the Final Scope from Step 6.
Required DEIS Components
Project description and purpose; existing environmental conditions; all reasonably anticipated impacts; a range of reasonable alternatives including no-action; mitigation measures; and irreversible environmental changes.
📍 Project Description
Full description — size, location, construction phases, operations, and connections to other projects in the area.
🌿 Existing Conditions
Baseline data for all environmental resources: soils, hydrology, vegetation, wildlife, air quality, traffic, and demographics.
⚡ Impact Analysis
Short-term, long-term, direct, indirect, and cumulative impacts on every resource identified during scoping.
🔄 Alternatives
Reasonable alternatives including the no-action alternative, with comparative environmental analysis.
🛡️ Mitigation Measures
Specific actions the project sponsor will take to avoid, minimize, or offset identified adverse impacts.
📊 Growth-Inducing Impacts
Whether the project could foster development beyond its direct footprint — a key concern throughout New York.
8Quality Control
Lead Agency Accepts the Draft EIS for Public Review
Before the Draft EIS goes to the public, the lead agency must formally review it for adequacy. This is a threshold determination — not whether the project should be approved, but whether the document is complete enough for meaningful public review.
The Adequacy Standard
The Draft EIS must provide sufficient information for the public and involved agencies to understand the proposed action and its environmental consequences. It must address every issue in the Final Scope.
✅
Accepted
The DEIS is adequate. A notice is published in the Environmental Notice Bulletin (ENB). The public comment period begins.
↩️
Returned
The DEIS is inadequate. The lead agency identifies deficiencies in writing and returns it to the applicant for revision.
Notice Requirements
Upon acceptance, the lead agency files the DEIS with DEC and publishes a notice in the Environmental Notice Bulletin (ENB), formally triggering the public comment period.
9Public Participation
Public Comment Period & Optional SEQR Hearing
The public comment period is where community members, neighboring municipalities, advocacy groups, and technical experts have the right to weigh in on the Draft EIS. All substantive comments must be addressed in the Final EIS.
Minimum 30-Day Comment Period
The public comment period begins when the ENB notice is published and must run for at least 30 days. Lead agencies routinely extend this for complex or controversial projects.
Who Can Comment
Anyone — members of the public, businesses, environmental groups, neighboring governments, state and federal agencies. No standing requirement to submit comments.
SEQR Hearing Option
The lead agency may hold a public hearing on the DEIS. Expected for high-profile projects. Hearing notices must be published in the ENB.
What Makes a Substantive Comment
Comments raising specific factual, scientific, or legal concerns must receive specific responses. General objections may receive more general responses.
The Comment Record
All written comments and hearing transcripts become part of the SEQR administrative record — central to any future legal challenge.
10Refinement
Revision of the Draft EIS (If Required)
After the public comment period closes, the lead agency evaluates all comments. If they reveal significant deficiencies or new issues not adequately addressed, the agency may require revisions before a Final EIS can be prepared.
When Revision Is Required
Revision is triggered when comments identify gaps in the impact analysis, inadequate alternatives, new significant impacts not previously considered, or insufficient mitigation measures.
🔍
Agency Reviews Comments
The lead agency categorizes all comments and determines whether revisions are needed or whether issues can be addressed in Final EIS responses.
✏️
Applicant Revises
If revisions are required, the applicant prepares a revised DEIS responding to identified deficiencies and re-submits to the lead agency.
📢
Additional Comment Period
If substantial revisions are made, the lead agency may open an additional public comment period on the revised sections.
➡️
Proceed to Final EIS
Once the lead agency is satisfied all significant issues are addressed, the project moves to preparation of the Final EIS.
11The Complete Record
Preparing & Filing the Final Environmental Impact Statement
The Final EIS (FEIS) is the culmination of the EIS process. It incorporates the full Draft EIS, all public and agency comments, and written responses to every substantive comment — forming the complete environmental record.
What the FEIS Must Contain
The complete Draft EIS (or incorporated by reference), a response to every substantive comment, any revisions, and a summary of significant adverse impacts that cannot be mitigated.
Responding to All Substantive Comments
Every comment raising a factual or analytical issue must receive a specific, reasoned response. Dismissive or generic responses are legally vulnerable.
Lead Agency Responsibility
The lead agency is responsible for the Final EIS. While the applicant often prepares it, the agency must review and accept it. The FEIS reflects the agency's judgment.
Filing and Distribution
The Final EIS must be filed with DEC and distributed to all involved agencies, the applicant, and anyone who commented. A notice is published in the ENB.
Mandatory 10-Day Waiting Period
A 10-calendar-day waiting period begins after the FEIS is filed. No agency may issue Findings or take final action until this period elapses.
12Final Decision
Agency Findings: Weighing Environment Against Benefits
After the 10-day waiting period, every involved agency must prepare written Findings before taking any action. The Findings statement is the agency's substantive conclusion that it has fulfilled its SEQR obligations.
The Balancing Test
An agency may only approve a project with significant adverse environmental impacts if it finds that the action's social, economic, or other benefits outweigh the unavoidable adverse environmental impacts, and all feasible mitigation has been incorporated.
Every Involved Agency Must Make Findings
Not just the lead agency. Every agency issuing a permit, granting a variance, or approving a plan must independently make its own Findings.
What Findings Must State
Findings must: (1) consider relevant environmental impacts; (2) weigh impacts against social, economic, and other benefits; (3) certify that adverse environmental effects have been minimized to the maximum extent practicable.
Mitigation Must Be Enforceable
Mitigation measures incorporated into Findings must be made conditions of the permit or approval. Vague commitments expose Findings to legal challenge.
Findings Are Publicly Filed
Findings must be prepared, filed, and made publicly accessible as part of the permanent SEQR record.
SEQR Review Is Complete
Once all involved agencies have issued Findings, the project can move forward — or must be denied if an agency cannot make the required findings.

We serve as SEQR counsel to planning boards, town boards, zoning boards, and village boards — advising on procedural requirements, significance determinations, and the legal standard for Negative and Positive Declarations.
2
EAF Review & Significance Determinations
We help boards complete Parts 2 and 3 of the EAF with the level of reasoning required by law — protecting the record from the most common ground for Article 78 reversal.
3
Scoping Facilitation
We guide municipalities through the scoping process — drafting the Final Scope, running scoping meetings, and ensuring the scope is comprehensive enough to withstand challenge while focused enough to be workable.
4
DEIS Adequacy & Comment Period Management
We advise on whether a submitted DEIS meets the adequacy standard, help manage public hearings, and ensure that all substantive comments are identified and properly addressed in the Final EIS.
5
Findings Statements & Litigation Defense
We draft legally defensible Findings that satisfy the balancing test under SEQR, and represent municipalities in Article 78 proceedings when SEQR determinations are challenged in court.
