VOLUNTARY CLEANUP PROGRAM

This site was cleaned up under the Voluntary Cleanup Program at Washington State Department of Ecology. The Voluntary Cleanup Program enables owners of contaminated sites to meet state cleanup standards independently and to receive technical guidance from Ecology during the process.

The Voluntary Cleanup Program enables owners to work on a contractual basis rather than under an Ecology legal order. Participants in the Voluntary Cleanup Program pay fees to Ecology to cover the department’s costs for guidance and review. Voluntary Cleanup Program sites must meet the same cleanup standards as properties formally managed by Ecology under the state’s cleanup law, the Model Toxics Control Act, created by a 1989 voter initiative.


CLEANUP ACTIVITIES

In early 2012, Seattle Public Utilities found PCBs (polychlorinated biphenyls), in stormwater runoff from the site and in sediment collected from an associated storm drain. A petroleum sheen was also visible on storm water flowing from the site. Ecology regulates contamination from both PCBs and petroleum because they can harm human and environmental health.

The source of the PCBs and petroleum sheen was an open container that caught and leaked rainwater. To correct the problem, Independent Metals covered their containers to prevent stormwater flowing through them and built a berm to reduce stormwater flowing offsite.

In 2018 and 2020, Independent Metals tested soil and groundwater and found that mitigation was successful and the site was in compliance with states cleanup standards.
