Determine NEPA/SEPA Strategy
Read Environmental Manual Chapter 300: Project scoping & programming (PDF 329KB) to learn more about determining project classification.
Determine if your project requires one or more federal agencies to take an action. The NEPA guidance on this page is applicable to projects with only a Federal Highway Administration (FHWA) nexus. If other federal agencies will take an action on your project, then you must contact those federal agencies to determine their process and requirements. Some agencies may accept the environmental documentation we prepare under FHWA’s NEPA process.
Use the Model Comprehensive Tribal Consultation Process for the National Environmental Policy Act to learn more about when and how to consult with tribes during the environmental review process. The tribal consultation process varies based on the project classification.
Check for past environmental documents related to your project. Reference, incorporate, or append any relevant information to the environmental document.
Use our NEPA/SEPA strategy checklist (PDF 615KB) to help develop a strategy for environmental documentation. Use this when Determining what discipline reports are needed (PDF 488KB).
Use the Federal Nexus Requirements (PDF 736KB) to understand which regulations your project must comply with based on WSDOT’s most common federal nexus types.
Use Environmental Review Summary (ERS) to document your environmental scoping as part of the Project Summary package. Copy this information into the ECS which serves as your NEPA document for Categorically Excluded projects.
Staff with a WSDOT login, follow these directions to gain access to ERS-ECS:

Planning and Environmental Linkages (PEL)
Planning and Environmental Linkages (PEL) studies consider environmental, community, and economic goals early in the transportation planning process. This can create more efficient outcomes for project delivery by eliminating duplication of effort between planning studies and the environmental review process. More information on PEL.
