Seattle City Light MIKE HAYNES, Interim General Manager and CEO
Skagit Relicensing Public Documents Library

As the current licensee for the Skagit River Hydroelectric Project, Seattle City Light intends to file an application for a new license no later than April 30, 2023, two years prior to the expiration of the current license, as required by statute. On April 27, 2020, City Light initiated the mandatory multi-year relicensing process by filing a Notice of Intent (NOI) to relicense the Project along with the Pre-Application Document (PAD) with the Federal Energy Regulatory Commission (FERC). City Light has convened a Steering Committee and Resource Work Groups to develop study plans that will inform the relicensing process.

Audience for these documents. Licensing Partners include federal, tribal and state agencies, non-governmental organizations and other interested parties. Documents are posted on this web page to support the participants’ engagement in the relicensing process.

What’s here. Click on the “plus sign” to reveal the document titles and links. Documents are organized under the headings that were developed during the study plan process.

The Pre-Application Document references approximately 200 documents which are posted on this web page and can be searched by title. In addition, as study plans and reports are completed, they will be posted here as well.

Note that confidential materials will not be posted on this web site.
Contact SCL_SkagitLibrarian@seattle.gov for additional help with accessing publications.
