Facility Site ID: 2017 Cleanup Site ID: 4425

This site has confirmed or suspected contamination that could potentially harm people and the environment. It is in the state cleanup process under the Model Toxics Control Act.

See the Site Details report at left or the documents below to learn more about this site.

Ecology works to clean up contaminated properties throughout the state. Cleanups are construction projects that remove, treat, or contain potentially harmful substances.

Site use restrictions called institutional controls are in effect

Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.

Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
