Cleanup site periodic review

June 4, 2020 - July 6, 2020, 11:59 p.m.

We invite the public to review and comment on the draft periodic review report for the Automotive Services cleanup site in Vancouver.

The Automotive Services site is on Mill Plain Boulevard. The report shows that cleanup work remains effective in protecting human health and the environment.

A car wash facility was constructed on the site in 1972–73. The facility used hot water mixed with kerosene to clean a protective coating off new cars after they arrived by ship at the Port of Vancouver. The car wash was demolished in 1998.

Kerosene and diesel-range petroleum contaminated the soil. The kerosene may have leaked from a pipe and the floor during car wash operations and from overflows of the facility’s water treatment system. The source of diesel-contaminated soil may have been a surface spill linked to a fuel storage facility and pipeline next to the site.

Most of the contaminated soil was excavated and bioremediated on-site by treating it with microbes to digest hydrocarbons. Some contaminated soil was not removed and remains buried at the site. A pavement cap covers the contaminated soil and prevents exposure of people and the environment. Groundwater is monitored at regular intervals.

An environmental covenant was recorded for the site in 2012 and updated in 2013. The covenant was required because the cleanup left kerosene and diesel concentrations in soil and groundwater that are above state cleanup levels. 

We conduct a periodic review at least every five years at cleanup sites where some contamination remains, 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.

We 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.
