The Cleanup and Tank Search application currently includes the following lists and reports

Brownfields Sites List

The Brownfields Sites List shows known brownfields cleanup sites in Washington State. Brownfield sites are abandoned or underused properties where there may be environmental contamination. Redevelopment efforts are often hindered by the liability for the cleanup or the uncertainty of cleanup costs. Brownfield sites that aren’t cleaned up represent lost opportunities for economic development and for other community improvements.

Cleanup Site Details Report

The Cleanup Site Details report shows detailed information about contaminated sites in Washington State. It is meant to be a more detailed snapshot of a cleanup site. This report also provides a link to available site documents, the site page, and a map.

Confirmed & Suspected Contaminated Sites List

This list contains information about sites that are undergoing cleanup and sites that are awaiting further investigation and/or cleanup. Sites on this list have received an Initial Investigation. Sites that have been ranked and are on the Hazardous Sites List are included in this data set. When sites receive a No Further Action determination, they are removed from this list.

Environmental Covenants Registry List

The Environmental Covenants Registry is a list of sites that have implemented institutional controls as part of the remedy. Institutional controls are administrative or legal measures used to prevent activities that may compromise the integrity of a cleanup action. They are meant to prevent exposure to contamination remaining on site. Institutional controls may include environmental covenants (also known as “deed restrictions”), zoning restrictions, public health advisories, or other administrative tools. The most common institutional control is an environmental covenant. Environmental covenants are legal recorded documents that typically limit certain uses of the property, such as:

  • Drilling a water supply well on the property.
  • Disturbing pavement covering contaminated areas.
  • Residential use of the property.
(Note: Ecology’s use of the term “Restrictive Covenant” has been replaced by “Environmental Covenant”.)

No Further Action (NFA) Sites List

This list contains information about sites formerly on the Confirmed and Suspected Contaminated Sites list that have received a No Further Action (NFA) determination. This includes sites that received a No Further Action letter:

  • During a Voluntary Cleanup Program (VCP) cleanup, where property owners independently clean up their sites but can ask for Ecology’s help.
  • During a non-VCP cleanup, such as when property owners independently clean up their sites outside the VCP, or when Ecology oversees the cleanup.
  • During the Initial Investigation or Site Hazard Assessment stage, which are two steps in the formal cleanup process.

Regulated USTs, All Active & Inactive Facilities List

The Regulated USTs, All Active & Inactive Facilities List shows all underground storage tanks (UST) at regulated facilities in Washington State. Previously, this list was separated into active facilities and inactive facilities due to the size of the list. To make searching easier, the lists are now combined, and a ‘Site Active’ filter is available if you only want to see active or inactive facilities, but not both.

Active facilities are defined as those having at least one tank with Operational, Temporarily Closed, Deferred, or Red Tag status.

UST System Summary Report

The UST System Summary report shows detailed information about regulated underground storage tanks in Washington State. It is a more detailed snapshot of an UST facility.

Voluntary Cleanup Program (VCP) Wait List (New)

The Voluntary Cleanup Program (VCP) Wait List (New) shows a list of VCP projects accepted into the VCP Program after the VCP Wait Lists were established, where there is no VCP Site Manager available to work on the project.
