Precision Engineering Inc. cleanup site Seattle

Draft Agreed Order and Public Participation Plan

Nov. 9, 2020 - Dec. 8, 2020, 11:59 p.m.

We are inviting public comment on cleanup documents for the cleanup of this site.

The Precision Engineering Inc. site is generally located at 1231 S Director St. in Seattle. This property is situated at the edge of the South Park neighborhood, near the western shore of the Lower Duwamish Waterway.

The following documents are available for review and comment:

  • Agreed Order — requires the potentially liable persons to complete a Remedial Investigation, Feasibility Study, and draft Cleanup Action Plan  for the site.
  • Public Participation Plan  Describes how Ecology will inform the community about site activities and opportunities to be involved in the cleanup process.

This site is being addressed under the formal Model Toxics Control Act Agreed Order process because past studies have shown contaminants to be present in soil, groundwater, and air at concentrations potentially harmful to human health and the environment. The work done under the Agreed Order will ultimately set the stage for a subsequent cleanup of the site.

This site is also being studied as part of Ecology’s Lower Duwamish Waterway source control efforts, because it may be contributing pollution to the Lower Duwamish Waterway (LDW) Superfund Site. The 5-mile stretch of the Duwamish River that flows north into Elliot Bay was added to the Superfund National Priorities List by the U.S. Environmental Protection Agency (EPA) in 2001. The sediments (mud) in the river contain a wide range of contaminants due to decades of industrial activity and runoff from urban areas. EPA is leading efforts to clean up the river sediments. Ecology is leading efforts to control sources of contamination from the surrounding land area. The long-term goal is to minimize recontamination of the river sediment and restore water quality in the river. 

The Precision Engineering Inc. site is one of numerous sites that will, or may, be cleaned up as part of Ecology’s Source Control Strategy. Contaminants in the soil and groundwater around the river pose a risk to human health and the environment. They can also find their way into the river through storm water runoff and other pathways.
