Environmental commitments & compliance

Environmental commitments are developed during project design, by consulting with regulatory agencies and tribes, through the NEPA/SEPA process (jpg 331 kb), and during permitting. Follow the procedures on this page to track environmental commitments and to report non-compliance events. 

Visit our Environmental disciplines page for discipline-specific compliance guidance. Review the Environmental sections in the Construction Manual (pdf 91 kb) for additional information on environmental compliance and commitment tracking. 

Tracking environmental commitments


Read Chapter 490: Tracking Environmental Commitments during Design of the WSDOT Environmental Manual to understand the policy context for tracking environmental commitments. During the design phase, start identifying and tracking commitments so they can be included in the design:  

Contract Preparation

See Chapter 590: Incorporating Environmental Commitments into Contracts of the WSDOT Environmental Manual for more information about the policies governing this work.

All environmental commitments are incorporated into construction contacts to ensure that our contractors incorporate the commitments into their work.



Prior to the start of construction

See Chapter 610: Preparing for Construction of the WSDOT Environmental Manual for the policy context.  Follow the procedures below to make sure that all the commitments are easy for the contractor to find and follow and that the contractor is prepared for environmental commitments before work begins.

During construction

Follow the procedures below during construction to check that the contactor is in compliance with the environmental commitments. See Chapter 620: During Construction of the WSDOT Environmental Manual.

Once construction is complete

Follow the procedures below to make sure that all the environmental commitments have been met. See Chapter 630: Close Out of Environmental Commitments of the WSDOT Environmental Manual.


Reporting non-compliance events

WSDOT maintains good relationships with regulatory agencies, tribes, and citizens by being honest about commitments and compliance. Accidents do happen and when they do WSDOT reports them promptly and the contractors adjust accordingly.

Use Chapter 1, SS 1-07.5, of the WSDOT Construction Manual – Environmental Compliance Assurance Procedure (ECAP) if there is a non-compliance event.
