Determine if you need a PSD permit
Option A: If you know your project needs a PSD permit, skip this step. Schedule a pre-application meeting with us.
Option B: If you want to make sure your project needs a PSD permit:
- Fill out an Application for a PSD Applicability Determination (as much as you can).
- Schedule a pre-application meeting with us (contact information below) and bring your Application for a PSD Applicability Determination.
For projects regulated by the Energy Facility Site Evaluation Council (EFSEC) or EPA Region 10 on tribal lands, contact those agencies.
Pre-application meeting for a PSD permit
We recommend meeting with Ecology staff before preparing a PSD application. At the pre-application meeting, we will:
- Coordinate the agencies involved in the project.
- Discuss your project, the PSD permitting process, and what to include in your application.
- Review the fee application that you must submit with the fee and project application.
To schedule a pre-application meeting, call or email the contact listed below.
- The applicant meets with Ecology and other agencies in a pre-application meeting to discuss the project.
- The applicant submits the fee and application with all the necessary technical information.
- If all the necessary technical information is included, we consider the application complete. If the application is incomplete, we notify the applicant to submit additional information.
- Once the application is complete, we draft a permit.
- We open a public comment period. We may also hold a public hearing, depending on public interest.
- We respond to public comments and make changes to the permit as necessary.
- If significant changes are made to the permit, we open another public comment period.
- If no significant changes are made to the permit, we issue a final permit.
