2012 CEQR Technical Manual The CEQR Technical Manual (the Manual) assists city agencies, project sponsors, and the public in conducting environmental reviews subject to City Environmental Quality Review (CEQR). The Manual (in PDF format below) summarizes CEQR procedures and provides guidance on the substantive areas of analysis customarily assessed in an environmental review. Applicability of the CEQR Technical Manual: The updated CEQR Technical Manual should be used as guidance for any environmental review commenced on or after February 2, 2012. In the case of impact analyses commenced prior to the release date that are not considered complete as of such date--through the issuance of a Negative Declaration, a Conditional Negative Declaration, or a Final Environmental Impact Statement--the lead agency should consider, taking into account as necessary the scheduled timing of completion of environmental review under the applicable regulatory approval process, whether supplementation of the impact analyses to reflect a methodology of the updated CEQR Technical Manual should be conducted.
