SEPA Review

The Draft Environmental Impact Statement (EIS) has been issued

Seattle City Light's consultant (Environmental Science Associates) has prepared a Draft EIS for the Denny Substation Project in compliance with the State Environmental Policy Act (SEPA).

SEPA provides decision-makers with the environmental information they need to consider when making decisions about projects. Comparing project alternatives in an EIS provides the project designers with the information they need to avoid or otherwise mitigate significant adverse environmental impacts.

The Draft EIS for this project analyzes three alternatives for substation design and three alternate routes for one new transmission line to serve the substation, in addition to the proposed distribution network. The Draft EIS for the project also evaluates installation of equipment called series inductors, at the proposed Denny and existing Broad Street Substation.

Public Hearing with Open House on the Draft EIS

To assist in the review and comment process, City Light will hold a public hearing on April 16, 2014 from 7:00 PM to 9:00 PM for individuals who may want to provide comments via oral testimony on the record. Oral testimony may be given in addition to or in place of written comments (as indicated above). Lynn Best, Director of the Seattle City Light Environmental Affairs and Real Estate Division will facilitate the hearing.

An open house will be held from 6:00 PM to 7:00 PM prior to the hearing to review EIS materials and findings and discuss the project with the EIS team.

To be captured for the record, oral comments must be provided to Ms. Lynn Best during the Hearing portion of the evening, not during informal discussions with staff during the Open House. Attendees may also choose to submit their written comments at any time during the Open House/Hearing.

Next Step After the Public Comment Period

To complete the SEPA process after Draft EIS issuance, City Light will prepare and issue a Final EIS in response to comments received on the Draft EIS. The Final EIS is now scheduled to be issued during the 4th quarter of 2014. The schedule for the Final EIS document will be refined as the project proceeds, and updates will be posted on this site. After the Final EIS is issued, the City Council and permit agencies will be able to make decisions on the project.
