Uptown Bakery

The Site is located in the Queen Anne neighborhood, northwest of downtown Seattle. The Site is contaminated with petroleum hydrocarbons in the gasoline, diesel and oil ranges, benzene, toluene, ethylbenzene and xylenes into the soil and groundwater. The source of that contamination has been attributed to petroleum releases on the nearby Queen Anne Properties (QAP) parcel and the a portion of the Site property related to the former Queen Anne Dye Works. Three underground storage tanks that contained ‘gasol’ were removed from the south side of the Site parcel in 1958. Soil and ground water analytical data and related chromatographic profiles indicated the presence of Stoddard solvent, a compound used historically in dry cleaning operations. 

​In 2010, soil vapor extraction was implemented as an interim cleanup action after a pilot test indicated that it would be effective on the Site. The cleanup action was conducted between December 6, 2010 and February 11, 2011. The objective of the interim action was to reduce concentrations of petroleum hydrocarbons in the unsaturated zone through the volatilization and extraction of soil vapors and the introduction of oxygen to enhance biodegradation.

In 2020, two previously unidentified underground storage tanks were decommissioned on the Site. On June 30, 2020, after confirming the tank contained no liquid, the westernmost tank was excavated and removed from the Site. The eastern tank contained approximately 400 gallons of liquid which was removed on June 29, 2020. Since the eastern tank is partially covered by a structure, its removal was not possible, and it was closed in place with controlled density fill.

In 2006, Ecology added the Site to the Hazardous Sites List (HSL). A Site Hazard Assessment (SHA) was conducted and the Site was ranked a “5” under the Washington Ranking Method (WARM). WARM ranking uses a scale of 1 to 5, where “1” represents the highest risk and “5” represents the lowest risk compared to other sites ranked. This ranking estimates the potential threat to human health and the environment relative to other ranked sites in Washington State.

The Model Toxics Control Act (MTCA) is Washington’s environmental
cleanup law. It provides requirements for contaminated site cleanup and sets
standards that protect human health and the environment. Ecology enacts the
MTCA and oversees cleanups.

​The MTCA site cleanup process is completed in steps over a variable timeline.

This site is in our Voluntary Cleanup Program, which provides technical help to owners of contaminated sites.

Voluntary Cleanup Program customers pay fees to cover our costs for technical help and reviewing cleanup reports. Sites in this program must meet the same cleanup standards as sites Ecology manages under legal orders.
