SEQR Handbook

Final SEQR Handbook (PDF) is available.

Since it first appeared in March 1982, the SEQR Handbook has been a standard reference book for state, county and local government officials; environmental consultants; attorneys; permit applicants; and the public at large.

The SEQR Handbook addresses common questions that arise during the process of applying SEQR. This 4th addition replaces the previous editions and reflects the State Environmental Quality Review (SEQR) process as it now stands. The major updates NYS DEC made to the document are additions to address the most recent revisions to the statewide SEQR regulations, Part 617 of Title 6 of New York's Codes, Rules and Regulations, adopted by the NYS DEC Commissioner on June 27, 2018 and which became effective January 1, 2019. Other changes include clarifications of existing sections to address questions or suggestions that NYS DEC has received since the 3rd edition of the SEQR Handbook was released in 2010.
