Site Description

Valley I5 RV is located at 23051 Military Road South, Kent, Washington. The property is occupied by a RV sales and service facility. Valley I5 RV occupied the property in the mid-1980s, and Kent Poulsbo RV is the current occupant. Surrounding property use is a mixture of residential and commercial.

Cleanup Activities

Three petroleum UST systems, including two 2,000-gallon gasoline USTs, one 1,000-gallon used oil UST, a pump, and associated fuel lines, were removed in 1998 from the southeast side of the southern building at the property. Contaminated soil extended to the glacial till at a depth of approximately 10 to 16 feet bgs.

Approximately seven cubic yards of impacted soils were removed and disposed of off-site. Soil sampling results indicated that petroleum contaminated soil exceeding MTCA Method A cleanup levels remained in the vicinity of the former gasoline USTs, very close to the southeast side of the southern building and possibly underneath the building.

Gasoline remains at the site at concentrations up to 1,200 milligrams per kilogram (mg/kg). Benzene remains at the site at concentrations up to 60 micrograms per kilogram (µg/kg). It was estimated that approximately 50 to 100 cubic yards of petroleum contaminated soils remain at depths greater than 10 feet bgs in this area. The residual contaminants do not appear to have impacted groundwater. The site is capped with pavement or building.

In summer 2022, the building on the southern end of the Site is planned for demolition as part of the extension of State Route 509. An additional remedial excavation is planned to a maximum depth of approximately 16 feet bgs to excavate the remaining soil with concentrations of gasoline and benzene above cleanup levels.

Regulatory Status

Following cleanup actions, petroleum hydrocarbons remain in soil at the site at concentrations exceeding cleanup levels. As a result, institutional controls through a restrictive covenant were implemented as part of the cleanup action, which restricts activities that might result in exposures to the contaminants. Ecology issued a no further action (NFA) determination for the site on November 16, 2006 through the Voluntary Cleanup Program (VCP). The NFA determination was contingent upon the restrictive covenant that was filed on the property on October 9, 2006.

Periodic Review

A periodic review is conducted every five years following a cleanup action when institutional controls are used as part of the remedy, as required by the Model Toxics Control Act (MTCA). The purpose of the periodic review is to evaluate current site conditions and to ensure continued protection of human health and the environment.

Periodic Review Results

The cleanup actions completed at the Site appear to be protective of human health and the environment.

Soil cleanup levels have not been met at the Site; however, the cleanup action was determined to comply with cleanup standards under WAC 173-340-740(6)(f), since the long-term integrity of the containment system is ensured and the requirements for containment technologies have been met.

The environmental covenant for the property is in place and continues to be effective in protecting public health and the environment from exposure to hazardous substances, as well as protecting the integrity of the cleanup action.

Based on this periodic review, Ecology has determined that the requirements of the environmental covenant continue to be met. No additional cleanup actions are required by the property owner at this time. It is the property owner’s responsibility to continue to inspect the Site to assure that the integrity of the remedy is maintained.

Model Toxics Control Act

Model Toxics Control Act Cleanup Process
Model Toxics Control Act Cleanup Process
The Model Toxics Control Act (MTCA) is Washington’s environmental
cleanup law. It provides requirements for contaminated site cleanup and sets
standards that protect human health and the environment. Ecology enacts the
MTCA and oversees cleanups.

​The MTCA site cleanup process is completed in steps over a variable timeline.

Voluntary Cleanup Program

This site is in 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 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.
