Slide 1

Corridor Planning and NEPA

Resource Agency Perspectives

Elaine Somers

EPA Region 10

Slide 2

SAFETEA-LU Sections 6001, 6002, Appendix A, and DOT Regulations are good!

  • Support purpose, intent of NEPA
  • Respond to CEQ NEPA requirement for early involvement
  • Facilitate consideration of environment in planning and project development
  • Foster other benefits of early involvement
  • Reflect common views/ needs of resource agencies

Slide 3

Appendix A

  • Consultation with agencies, Tribes re: conservation plans, maps, resource inventories, mitigation
  • Early and continuous involvement
  • Level of detail
  • Thorough documentation
  • Sound, credible analyses using reliable data, rational up-to-date assumptions
  • Purpose and need guidance
  • Initiating NEPA with planning studies guidance
  • Use of planning info for affected environment, environmental consequences, indirect and cumulative effects
  • Makes no guarantees

Slide 4

Corridor Planning in EPA Region 10

  • ITD District 6 — active user; encouraged statewide
  • WA — pre-SAFETEA-LU: limited tiering, corridor planning within NEPA
  • Oregon CETAS process — a successful model

Slide 5


  • Colorado DOT
    • Dedicated staffing: Planning and Environmental Linkages (PEL) Manager
    • Linking Planning and NEPA training: online, interactive
    • PEL Decision Tool: web-based, interactive
    • FHWA PEL Questionnaire: level of detail guidance; planning documentation
    • Resource agency coordination: Environmental forum
    • Many corridor studies

Slide 6

Idaho Corridor Planning and NEPA Integration Guide

  • 5 approaches:
    • 1 tiered
    • 3 within NEPA umbrella
    • 1 outside/ prior to NEPA (for when streamlining is not necessary)

Slide 7

Corridor/ subarea plans — to use or not to use?

  • Transportation planners must evaluate situation, pros/ cons
  • Resource agencies want early and continuous involvement
  • Prefer within NEPA umbrella

Slide 8


  • Urge use of "within NEPA" approaches
  • Ensure each resource agency, Tribe is invited to participate from the beginning
  • Create ways to enable participation
    • Site visits, teleconferences, videoconference, environmental forum (ala CDOT), electronic communications, clustered meetings/ site visits for out-of-area participants, other
  • Have inclusive, continuous public involvement
  • Use Appendix A guidance

Slide 9

More offerings

  • At a minimum, follow procedures for participating/cooperating agencies (S. 6002) in planning and project development, i.e., have check-in points.
  • Consider whether to establish an interagency MOA, with formal concurrence or consultation points, conflict resolution process, and other features.
  • Determine means and methods for documentation.
  • Use Origin/Destination studies to inform planning.
  • For success, ensure corridor planning is inclusive, manageable, appropriately iterative, and result in more informed decision making, per intent of NEPA.
