Periodic Review Draft Report Completed

Ecology invites you to review and comment on a document called a periodic review for the Stevens Pass Ski Resort Vehicle Maintenance Facility 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. 


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.

The Stevens Pass Ski Resort Vehicle Maintenance Facility Site currently operates as a vehicle maintenance facility and was constructed in 1980. The facility is located south of Highway 2, near the bottom of a ski run.  Vehicle fueling occurs at the facility and at the time of the remedial action, two underground storage tanks (USTs) were in use—a 10,000-gallon UST that contained diesel and a 4,000-gallon UST that contained unleaded gasoline. The USTs were installed in 1988, replacing the two USTs that had been originally installed in 1980.  Several aboveground storage tanks are located at the Site to support maintenance activities. 


A remedial action was conducted at this site from August through November 2011.  Approximately 3,000 tons of soil were removed from both the southern and northern excavations.  Over 15,000 gallons of groundwater within the excavation were hauled to the treatment system at the former mini mart location and treated using carbon adsorption and reinfiltrated.  Contaminated soil remains at a locations adjacent to and underneath a structure at the site; this location has been capped with 8” concrete.  Groundwater monitoring was performed from November 2011 through 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. 


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.
