DOT&PF Environmental Manuals

The Federal Highway Administration (FHWA) and DOT&PF have developed and signed a Memorandum of Understanding (MOU) that allows the FHWA to assign to the State of Alaska the responsibility for determining whether a project is categorically excluded from preparation of an environmental assessment or an environmental impact statement.  The MOU also assigns to the State certain responsibilities for conducting environmental reviews, consultations, and related activities for Federal-aid highway projects.

The Alaska DOT&PF Environmental Procedures Manual identifies environmental requirements to be followed on highway projects under the NEPA Assignment Program, in compliance with terms of the NEPA Assignment Program Memorandum of Understanding between FHWA and DOT&PF dated April 13, 2023. This manual was enacted by Chief Engineers Directive on February 9, 2018. This manual replaces the Alaska 6004 Program Environmental Procedures Manual.

This page also includes the latest class of action and categorical exclusion forms to be used in conjunction with these manuals.
