Fort Vancouver Plywood Site

Cleanup Site Periodic Review

Nov. 5, 2020 - Dec. 6, 2020, 11:59 p.m.

Environmental cleanup is complete at the site and the draft third periodic review report shows the cleanup work remains effective in protecting the health of people and the environment. Additional information is available at the Fort Vancouver Plywood webpage.

The site consists of 15.8 acres where the former plywood mill was located. Contamination was linked to burial of industrial debris. Metals including lead and leachable arsenic, carcinogenic polyaromatic hydrocarbons, and petroleum hydrocarbons were found in soil above state cleanup levels. Arsenic, phthalates, vinyl chloride, and petroleum hydrocarbons were found in groundwater above cleanup levels. 

Cleanup included removal and proper disposal of contaminated soil and wood waste. The excavation was backfilled with clean soil and covered by an asphalt cap.

Groundwater is monitored regularly. Results show that vinyl chloride and petroleum hydrocarbons were present above state cleanup levels in one monitoring well. The concentrations of these two contaminants is decreasing over time. None of the other contaminates were detected in groundwater above laboratory detection limits.

After cleanup, environmental covenants were filed for the property. Among other things, the covenants prohibit activities that could result in the release of contaminants on the Site. The covenants restrict the land to industrial use. Groundwater may not be taken from the site for drinking or for agriculture.

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.
