Statewide SEPA register

We publish a web-based SEPA Register that is updated immediately after data entry. It includes all SEPA and NEPA documents submitted to us. All SEPA lead agencies must submit documents to us in a timely, accurate manner.

Procedure for submitting documents

Lead agencies are responsible for submitting documents promptly using our established procedures. All documents submitted to the SEPA Register must be received in an electronic format (via e-mail, flash drive, or CD) and all SEPA EISs must also be submitted with one hard copy. 

Tips and reminders:

  1. Any SEPA document with a comment period must be submitted to the Register including:

    • Determinations of nonsignificance (DNS)

    • Mitigated determinations of nonsignificance

    • Notices of application /optional DNS process

    • Draft Environmental Impact Statements (EIS)  — including Draft Supplemental

    • Determination of Significance/Scoping notices

  2. All Determinations of Nonsignificance and notice of applications using an optional DNS process must include the Environmental Checklist  — unless there is an adoption of previous SEPA or NEPA document.

  3. Some documents without a comment period must be submitted to the Register including:

    • Determination of Nonsignificance/Notice of decision using Optional DNS process

    • Determination of Significance with adoption notices

    • Notice of action taken

    • Final EISs

    • Email and mailing address for environmental impact statements (CDs or hard copies)

  4. Some SEPA documents and all NEPA documents are not required to be submitted, but Ecology enters them into SEPA Register if received.  These include, but are not limited to:

    • Determinations of Nonsignificance (DNS) without a comment period: Note: Please include checklists

    • Interagency pre-threshold consultations  — or “draft Checklists”

  5. ​​​Please send us your documents prior to or on the day of issuance so we can upload them as soon as possible.  Note that the SEPA comment period and public notice provisions are determined by the day the document is sent from the lead agency, not the date we post it on the Register.

    • We do not provide notification to the lead agency that a document has been posted on the SEPA register. The register gets updated instantly and lead agencies can check the SEPA register to ensure the document was correctly listed on the database.

  6. It is not necessary to send us a scanned copy because this PDF format produces an excessively large file. Instead, include the name of person signing and the date instead of scanning a signed copy.  Send them as a .doc, .docx, .jpg, .jpeg, .pdf, or .png file type.

    • Email to: separegister@ecy.wa.gov. Each email message should be no larger than 30 MB. In the text of the email, please be sure and include: The type of SEPA document, a description of the proposal, date of issuance, and the lead agency contact information.

    • Include a Web link — Please post additional information with large file sizes –such as maps, site plans, reports and other information needed to review the SEPA submittal. Please provide a link to the lead agency’s website to include in the SEPA Register record.

    • Mail a CD — A Instead of submitting large electronic documents by email, we also accept compact disks and flash drives.

    • No hard copies  — except one copy of SEPA EISs (including Supplemental)

  7. Please send us your documents prior to or on the day of issuance so we can upload them as soon as possible.  Note that the SEPA comment period and public notice provisions are determined by the day the document is sent from the lead agency, not the date we post it on the Register.
