Chelan County Fire District 1
206 Easy St, Wenatchee, WA 98807-2106

PUBLIC COMMENT PERIOD AUGUST 30, 2017-SEPTEMBER 29, 2017

 
The Washington State Department of Ecology (Ecology) is proposing to remove the Chelan County Fire District 1 Site, located at  206 Easy Street, Wenatchee,  Washington, from its Hazardous Sites List.  The Hazardous Sites List is a statewide list of contaminated properties.  The Site is currently ranked a “5” on the list.  A rank of “1” is the highest level of concern compared to other sites on the list, and a rank of “5” is the lowest.
 
Ecology is asking for your comments on the proposed removal of the Site from the Hazardous Sites List. You are invited to:
 

  • Review the Chelan County Fire District 1 (NFA) and the Chelan County Fire  District 1 Data Gap Investigation
  • Send your comments to Ecology for consideration.  Comments will be accepted August 30, 2017, through September 29, 2017


SITE DESCRIPTION

The Site formerly consisted of a county operated fire station, sheriff’s helicopter hanger, a fire tower, and a county yard.  The helicopter hanger is no longer in use.  In January 1995, two two underground storage tanks (UST's) were decommissioned and removed from the Site.  The UST's consisted of one 500-gallon diesel tank and one 1000-gallon gasoline tank.  A site visit made in May 2007 confitmed that the site was almost completely paved with concrete.
 
After a Site Hazard Assessment conducted in 2007, the Site was ranked a “5” on the Hazardous Sites List.  The Hazardous Sites List is a statewide list of contaminated properties.  Sites can be ranked from a “1” to “5”.  A rank of “1” is the highest level of environmental concern compared to other sites on the List, and a rank of “5” is the lowest.


CLEANUP ACTIVITIES

During tank removal and excavation, soil samples were taken from the excavation sidewalls, below the UST's, and beneath the dispenser island location.  One of the samples taken near the dispenser had a concentration of 1500 mg/kg TPH-D, which exceeded the Method A cleanup level in existence in 1995.
 
Based upon field screening results, soil was excavated soil from the area of the fuel dispenser in addition to soil excavated from the UST area for a total of approximately 60 cubic yards.  Complete excavation of the potentially impacted soil was not accomplished because additional soil removal would have endangered the fire tower structure.
 
Upon completion of remedial activities, the excavation was filled with imported soil.  Soil samples from the stockpiled excavated soil were analyzed for diesel and gasoline range hydrocarbons.  One of the samples showed diesel concentrations above MTCA Method A cleanup level of2000 mg/kg.  All other parameters were below MTCA Method A cleanup levels.  The stockpiled soil was completely removed from the site and disposed at the Greater Wenatchee Regional Landfill.
 
Additional soil samples were collected to characterize the final remedial excavation.  The samples were analyzed by for gasoline and diesel range hydrocarbons.  Only one sample exceeded the MTCA Method A cleanup level for diesel.
