K Ply

The K Ply site, which is also known as PenPly or Peninsula Plywood, is located at 439 Marine Drive in Port Angeles.

From 1941 - 2011, a plywood mill operated on the K Ply property under various owners. The Port of Port Angeles (port) owns the property.

Past operations contaminated soil and groundwater. Known site contaminants include:

Rayonier operated a plywood mill on the K Ply property from 1971 - 1989. During that time, a hydraulic oil leak contaminated a part of the site.

Past Cleanup
Ecology entered into an agreed order with the port to separate K Ply from the Marine Trades Area site in October 2012. Investigations of the Marine Trades Area site from 2005 - 2011 showed that there are separate sources of contamination on the two sites.

The October 2012 agreed order required the port to do a partial cleanup and develop a remedial investigation report, feasibility study, and preliminary draft cleanup action plan for the K Ply site.

In 2013, the port completed a partial cleanup in which they tore down former mill structures and stabilized the site.

Ecology held a public comment period for draft reports, cleanup plans, and a legal agreement for cleanup from April 2 – May 4, 2015. You can read the comments we received and our responses in the responsiveness summary. Ecology signed a new agreed order to implement cleanup in 2015.

The port began cleanup in August, 2015.
Under the cleanup action plan and agreed order, the port:

  • Removed over 50,000 tons of polluted soil. They kept clean soil on site and reused it during construction.
  • Used bioremediation to clean up polluted groundwater. They added nutrients and oxygen to excavated areas before adding clean soil. The nutrients and oxygen will encourage natural organisms to grow. These organisms will then use contaminants for food, which will break down the contaminants. This will result in lower contaminant levels. 
  • Continues to monitor soil and groundwater until cleanup standards are met.

You can view the Construction Completion Report, which details the cleanup activities that took place on site, and other cleanup related documents below.
