PUBLIC COMMENT PERIOD SEPTEMBER 27, 2018-OCTOBER 29, 2018

Periodic Review Draft Report Completed

Ecology invites you to review and comment on a document called a periodic review for the Stevens Pass Mini Mart Station Site.  A periodic review is conducted at least every five years after the initiation of a cleanup action at a Site when required by the Model Toxics Control Act (MTCA).  The purposes of the review are to evaluate Site conditions after cleanup is considered complete, and to ensure 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.

You are invited to:

  • Review the Periodic Review Report.
  • Send your comments to Ecology for consideration. Comments will be accepted September 27, 2018 through October 29, 2018. 
The Periodic Review Report is available for review below and at the View Electronic Documents link in the right navigation pane.  These documents are also available for review at the repository location listed in the right navigation pane.  Please submit any comments online or by mail to Jeff Newschwander, Periodic Review Coordinator, at Ecology's Central Regional Office. 


SITE DESCRIPTION

The Stevens Pass Ski Area operates on two areas of U.S. Forest Service (Forest Service) land (a total of 2,463 acres), pursuant to a special use permit issued by the Forest Service as well as on a 32-acre privately held parcel referred to as Yodelin.

An April 2010 Phase I environmental site assessment and May 2010 a Phase II assessment reported contamination in two areas, the Stevens Pass Mini Mart Station Site (former) and Stevens Pass Ski Resort Vehicle Maintenance Facility Site.

At the Stevens Pass Mini Mart Station Site (Site) a gas station was constructed on the subject property, along the northern side of Highway 2, in 1960 and it operated until 1971.  At one time, a gasoline aboveground storage tank (AST) and an oil AST were located behind the station building.  In 1964, five USTs were installed at the station.  Two of the tanks contained heating oil, one contained leaded gasoline, one contained unleaded gasoline, and one contained waste oil.  All five of these USTs were reportedly removed. The station building was demolished in 1998.
 
In 1948, the Washington State Department of Transportion (WSDOT) constructed a building to the northeast of the future Mini Mart station area that was used for vehicle maintenance. WSDOT operated the maintenance facility until 1968, when most of the building was demolished.  From 1968 to 1980, Stevens Pass used the remaining portion of the building for vehicle maintenance. The remaining building still exists, but is only used by Stevens Pass for Parking and Transit Operations offices and equipment/supply storage.


CLEANUP ACTIVITIES

A remedial action was conducted at the Site from August through November 2011.  Approximately 17,000 tons of soil were removed from both the southern and northern excavations.  Over 400,000 gallons of groundwater within the excavation were treated using carbon adsorption and reinfiltrated onsite.  Contaminated soil remains at several locations adjacent to and underneath structures at this site; these sites have been capped with either 8” concrete or 6” of asphalt.  Groundwater monitoring was performed from November 2011 thru August 2012 to confirm cleanup.  An environmental covenant has been placed on the property identifying locations on the property impacted with total petroleum hydrocarbons above cleanup levels.


CLEANUP COMPLETE

Based upon cleanup activities and the placing of the environmental covenant, Ecology has determined the site is no longer a threat to human health and the environment.  Ecology made a No Further Action determination in March 2013.
