Univar Solutions USA Inc.

Dangerous Waste Corrective Action Permit Renewal

June 22, 2020 - Aug. 5, 2020, 11:55 p.m.

We invite you to review and comment on a draft permit and draft public participation plan for the Univar Solutions USA Inc. facility in Kent, WA.

Permit renewal

The permit, called a Dangerous Waste Corrective Action Permit (.doc), allows environmental cleanup activities at this site to continue. The permit meets requirements of the Resource Conservation and Recovery Act (RCRA), the federal law that outlines how to properly manage hazardous waste. Univar’s RCRA permit is up for renewal at this time.

Public Participation Plan

The purpose of the Public Participation Plan (PPP) is to encourage community involvement during the permit renewal process. The plan describes how we inform the community about the permit renewal process so they can know about decision-making opportunities. It outlines how and when people can get involved during the permit renewal process for Univar.

We will consider all comments and may amend the documents based on them. The permit and public participation plan will become effective following the public comment period. We will hold a virtual public meeting if 10 or more people request one.


Univar Solutions USA Inc. no longer stores dangerous waste at their Kent facility. However, federal regulations require facilities to have a hazardous waste permit until all cleanup is complete. This permit must be renewed every 10 years.

Univar is a global company that stores, packages, and distributes chemical products. The Univar facility in Kent has a warehouse, office, dock, and parking areas on an 11-acre site, surrounded by other commercial and industrial properties.

Most of the groundwater contamination is located beneath the property, but some contaminants in the deeper groundwater flowed north under 212th Street and beneath an adjacent industrial property. No drinking water wells are present in or near the areas of contamination.

We issued an agreed order (a legal agreement) requiring Univar to plan and implement a site cleanup. In 2009, we selected the preferred cleanup activities from the Feasibility Study.

Since then, Univar has been implementing the Cleanup Action Plan. This includes treating groundwater with “enhanced reductive dechlorination.” This injects special bacteria underground into polluted groundwater so the engineered bacteria “eat” the contaminants. The groundwater at the site is tested regularly to see if the pollutants are breaking down into less harmful chemicals.
