Pierce Transit Sprague Ave

Cleanup Site Periodic Review

January 17, 2019 - February 19, 2019

Ecology invites the public to review and comment on the draft periodic review report for the Pierce Transit Sprague Avenue site. The report for the site shows that cleanup work remains effective in protecting human health and the environment.

In 1986, approximately 400 gallons of waste oil was recovered from an oil recovery trench and sump leaving hydrocarbon contamination below the structure of the boiler room.  Cleanup activities in 1990 and 1991 included removal of approximately 3,700 cubic yards of petroleum-contaminated soil and elimination of about 45,000 gallons of oily water from where the soil was excavated.  In 1998, ten underground storage tanks were removed from Pierce Transit’s facility.

Some contaminated soil was left in place at three locations because they were located under the foundation of the building.  The remaining contaminated soil at the site was capped with pavement or sealed under the building to eliminate people’s contact with the contamination.

Long-term monitoring of groundwater shows that pollutant concentrations are not detected.

In 2013, a restrictive covenant was filed for the site that requires regular, periodic groundwater monitoring and maintenance of the pavement and building that cover contaminated soil to make sure contamination does not pose a threat to human health and the environment.
 
 

Ecology conducts a Periodic Review at least every five years after the initiation of a cleanup action at a site, as required by the Model Toxics Control Act (MTCA). The purposes of the review are to evaluate site conditions and to ensure continued protection of human health and the environment when institutional controls are part of a cleanup.

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.

Ecology will hold a public meeting if 10 people request one.
