Camp Korey at Carnation Farm
Site Description
Carnation Farm has been in operation since 1909. The Site has been used primarily as a dairy farm. A 10,000-gallon leaded gasoline underground storage tank (UST) was installed in 1971 and decommissioned in 1989, and a 5,000-gallon unleaded gasoline UST was installed in 1976 and decommissioned in 1995. A 22,000-gallon above ground storage tank (AST) was installed sometime in the 1920s and supplied fuel oil to a steam boiler. The AST was removed in May 1993.
It was determined after excavation and sufficient groundwater monitoring that the PCS no longer posed a threat. There was no threat to human health by direct contact because the structures covered the contamination, and no longer a threat to groundwater based on four consecutive quarters of clean sample results. A restrictive covenant was recorded for the Site in July 1998, and in August 1998, a ‘No Further Action’ determination was issued.
Voluntary Cleanup Program
This site was cleaned up under our Voluntary Cleanup Program, which provides technical help to owners of contaminated sites.
Voluntary Cleanup Program customers pay fees to cover our costs for technical help and reviewing cleanup reports. Sites in this program must meet the same cleanup standards as the sites Ecology manages under legal orders.
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.
