SITE DESCRIPTION

The Site is located on Front Street in the waterfront area of the Town of Friday Harbor on San Juan Island. The Site includes a vacant property owned by the Port of Friday Harbor (tax parcel number 351350502000) and the north-adjacent Front Street right-of-way owned by the Town of Friday Harbor.

The Site is defined by petroleum releases to soil and groundwater associated with historical operations of a Unocal bulk plant which stored and distributed gasoline and diesel fuel between 1924 and 1983. The bulk plant facility included above ground storage tanks (ASTs), a garage, a concrete containment wall down slope of the ASTs, and a truck loading rack outside the containment wall (eastern side). Underground and aboveground steel pipelines formerly connected the storage tanks with a fuel dock. The pipelines have also been removed.


CLEANUP ACTIVITIES

Approximately 3,710 tons of petroleum-contaminated soil and 6,000 gallons of petroleum-impacted groundwater with free product were removed from the Site in 2002. Contamination remained in a localized area along the west wall of the excavation. The area was near a grove of trees and could not be safely excavated further without removing the trees or excavating near an active electrical line.

The remaining contamination is in the right-of-way in the vicinity of a concrete stairway that leads up the slope to 1st Street. Institutional controls through a Restrictive Covenant were implemented at the Site as part of the cleanup action.
 


REGULATORY STATUS

Ecology issued a no further action (NFA) determination for the Site on October 23, 2003 after a Restrictive Covenant was recorded for the Site to restrict activities that might result in exposures to the contaminants. This was issued through the Voluntary Cleanup Program (VCP).

The NFA determination also required a groundwater compliance monitoring program to assure the Site does not pose a threat to human health or the environment. Quarterly groundwater monitoring began in November 2004. Results indicated that the Site had four consecutive quarters below MTCA Method A cleanup levels. In 2006, Ecology issued a second NFA determination that no longer required groundwater monitoring.
  


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.

The Restrictive 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.
