Denny Substation reaches a major milestone as site cleaned up to residential standards

Seattle City Light recently completed the environmental cleanup at the site of the future Denny Substation. City Light purchased the site, the former Greyhound Bus Maintenance Facility, in 2009, with the intention of building a new electrical substation in North Downtown to keep pace with Seattle’s growing power needs. Due to historical leakages of gasoline, diesel, and waste oil, the site needed to be cleaned up. City Light developed a plan to remediate the site to a level consistent with residential standards contained in the Washington State Model Toxics Control Act (MTCA).

City Light completed Phase 1 of the plan in late 2012 when it demolished the Maintenance Facility and removed underground storage tanks. Phase 2 began in early 2013 and included removal of contaminated soils, installation of a stormwater detention system, and backfilling the site with clean dirt.

The site is now ready for construction; however, the environmental review and design of the substation needs to be complete before construction begins. In the meantime, a temporary arts program will occupy and enliven the site until construction begins in early 2015.

About the Denny Substation Project
The new substation will be located near Denny Way and Stewart Street. It will ensure reliable power for some of the city’s fastest growing areas, including the South Lake Union, Cascade, Denny Triangle, Uptown, Belltown, and First Hill neighborhoods, as well as other customers throughout City Light’s service area.

More information on the Denny Substation Project, including its substation, distribution network, and transmission line, can be found at: www.seattle.gov/light/dennysub
