A plain-English guide to New York State's environmental review law and what it requires before major projects are approved.
SEQRA — the State Environmental Quality Review Act — is a New York State law that requires government agencies to consider the environmental impacts of their decisions before approving major projects or actions. Enacted in 1975, SEQRA applies to any project requiring a government permit, approval, or funding. It does not block development, but it does require a thorough, public analysis of environmental consequences before approvals can be granted.
Presumed to have significant environmental impact. Require a full Environmental Impact Statement (EIS). Large developments, projects near sensitive resources, rezonings.
Exempt from SEQRA. Routine maintenance, minor repairs, small projects below set thresholds.
Between Type I and Type II. Agency determines significance using a short Environmental Assessment Form (EAF).
How the project fits existing land use plans and zoning.
Vehicle trips generated, road capacity impacts.
Demand on water supply and sewage treatment capacity.
Drainage, runoff, and flood risk impacts.
Wetlands, wildlife habitat, agricultural land impacts.
Noise, visual impact, effect on neighborhood quality.
One government body is designated as Lead Agency to coordinate the SEQRA review.
The applicant submits an EAF. The Lead Agency reviews it to determine whether a full EIS is needed.
Lead Agency issues either a Positive Declaration (full EIS required) or Negative Declaration (no significant impact found).
If required, a Draft EIS is prepared and circulated for public comment. Hearings may be held.
Lead Agency reviews all comments and issues a Findings Statement before any approval can proceed.
The proposed Route 14A development — a 500-unit housing project — is subject to SEQRA review by the Penn Yan Planning Board as Lead Agency. Residents and advocates have raised concerns that key studies on traffic, sewer capacity, electric load, and stormwater have not been made publicly available before planning approvals advance. SEQRA requires these impacts to be fully analyzed and disclosed before final approval.
