Wasser Winters site

Cleanup site periodic review

Aug. 1, 2019 - Sept. 1, 2019

Ecology invites the public to review and comment on the draft second periodic review report for the Wasser Winters site. The report shows that cleanup work remains effective in protecting human health and the environment.

The Wasser Winters site is a former log-sorting yard leased from the Port of Tacoma. From 1977 to 1980, rock, gravel, and slag from the former Tacoma Asarco Smelter was brought to the site to build stable ground to support heavy machinery and log piles. Metals were found in surface water above industrial cleanup levels.

In 1993, the port installed a stormwater collection system and wells to monitor groundwater.  A low permeability asphalt cap covered the contaminated soil at the site. A 100-foot wide stream buffer was left between the asphalt cap and Hylebos Creek for wildlife habitat. Groundwater was monitored from 1993 to 2000 and Ecology determined the site required no further cleanup and removed the site from the Hazardous Sites List.
 
An environmental covenant was filed for the site in 1994, which limits use of the site to industrial purposes and prohibits any activity that may interfere with or reduce the effectiveness of the cleanup. The owner must maintain the cap and stormwater collection system. Monitoring for metal in groundwater and review of the asphalt cap is done every 30 months.

We conduct 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. An additional public comment period will be held if significant changes are made.

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