PUBLIC COMMENT PERIOD MAY 10, 2019-JUNE 10, 2019

Ecology invites you to review and comment on the periodic review for Valley I5 RV (also known as Kent Poulsbo RV) located at 23051 Military Road South, Kent, Washington.

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.

Ecology will review comments received during the comment period and make recommendations for suggested changes. The periodic review will become final if no significant changes are made. An additional public comment period will be held if significant changes are made.

Send your comments to Tamara Welty, Site Manager at 3190 160th Ave SE., Bellevue, WA 98008 or on-line at: http://cs.ecology.commentinput.com/?id=mbh6i

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.


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.
