Bothell Riverside HVOC cleanup site

Public Comment Period

Nov. 21, 2022 - Dec. 22, 2022, 11:59 p.m.

Ecology and the City of Bothell are moving forward with the cleanup of this site in the downtown Bothell area. We invite your comments on the cleanup plan and other documents.

The Bothell Riverside HVOC site is one of six sites in the historic downtown area that have received grant funding from Ecology to help with the cost of cleanup. Last month, Ecology held a comment period for the Ultra Custom Care Cleaners site, which is a few blocks north of this site.

We invite you to review and comment on the following documents:

  • Agreed Order: A legal agreement between Ecology and the City requiring the city to investigate the contamination, share different methods for cleaning it up, and create a draft cleanup plan for Ecology’s selected cleanup method.
  • Supplemental Remedial Investigation/Feasibility Study: A description of the nature and extent of the contamination, evaluation of ways to clean up the site, and a recommendation of a preferred cleanup option.
  • Draft Cleanup Action Plan: A description of Ecology’s selected cleanup action and the specific cleanup standards for this site.

Background

The Bothell Riverside HVOC Site is around NE 180th Street & Woodinville Drive (SR 522) in Bothell. In 2008, the City acquired the property as part of the Highway 522-Woodinville Drive realignment and downtown revitalization effort. This property was called the Riverside Cleanup Site.

The city investigated the contamination on the site and found that there were two separate contamination sites, with different types and sources of contamination. The property was divided into two cleanup sites: the Riverside TPH Site and the Riverside HVOC Site. The TPH site was cleaned up in 2017.

HVOCs (Halogenated Volatile Organic Compounds) and their breakdown products are believed to have entered the soil and groundwater at the Riverside HVOC Site from operations at a former machine maintenance shop.
