Background

Rayonier Properties LLC (Rayonier) operated a pulp mill in Port Angeles from 1930 until 1997, when they closed and dismantled it.  Over the years, the mill emitted hazardous substances that still pollute the land and water.  Ecology is working with Rayonier to investigate the contamination and clean up the environment.

Location

The former pulp mill is located at 700 North Ennis Street in Port Angeles.  The mill property sits on Port Angeles Harbor, at the mouth of Ennis Creek.  Map  (To enlarge photo, please pause briefly for the square orange icon to appear on the bottom right of the next photo, then click it to view the full size photo.)
 
The boundaries of the cleanup site have not yet been set.  The site is defined by the extent of contamination caused by the release of hazardous substances.  Further work is needed to determine where the contamination has reached. 
 
The Study Area is Rayonier’s responsibility to investigate until the full site can be identified.  It is the portion that includes:

• Property owned or leased by Rayonier; and
• Marine sediments next to the property.

Ecology will investigate two areas outside of the Study Area to help determine the extent of contamination from Rayonier or other potential sources.

• Port Angeles Harbor Sediments Study
• Rayonier Mill Off-Property Soil Dioxin Study -

History

The first sawmill on what is currently Rayonier property was built in 1887 and abandoned just six years later.  In 1917, the U.S. Government built a new sawmill to mill spruce for aircraft.  After sitting idle for several years, the mill was bought by Olympic Forest Products in 1929 and rebuilt as a pulp mill.  Rayonier bought the new pulp mill and operated it from 1930 until 1997.
 
The mill produced pulp using what is called a sulfite process.  Sulfite and acid were used to break down wood to get out the cellulose—the fibers that make up paper and other products.  The pulp from the Rayonier mill was sold to companies that made photographic film, fabrics, and plastics.

Contamination

The mill’s pulp-making process involved several industrial chemicals. In the early years, the mill discharged untreated liquid wastes and byproducts (spent cooking liquor) directly into the Port Angeles Harbor.  During the 1970s, the mill began treating this waste water before discharging it.  Primary and secondary treatment systems were put in place and discharges were sent through a deep-water outfall more than a mile offshore in the Strait of Juan de Fuca. The mill added sludges from the treatment system to wood chips and burned it to generate steam.
 
When these industrial wastes were released into the environment, they carried pollutants into the air, water, and soil.  These pollutants have been detected within the study area: 

• Petroleum hydrocarbons such as hydraulic or fuel oil.
• Polychlorinated biphenyls (PCBs) from electrical equipment.
• Lead from a lead-based mortar between bricks inside part of the mill.
• Dioxins  and furans from ash.
• Arsenic

From Operations to Cleanup

Rayonier closed their Port Angeles mill in March of 1997.  That year, a group of individuals and organizations petitioned the U.S. Environmental Protection Agency (EPA) to investigate the site.  Based on an extensive study, EPA concluded that the site was eligible for the Superfund  program.  However, state and local officials asked that the site be cleaned up under Washington’s Model Toxics Control Act.  In 2000, EPA decided to let Ecology clean up the site.

In 2007, Ecology gave the City of Port Angeles a grant to explore visions for the future use of the Rayonier site. The City has brought together a diverse group of stakeholders to begin this process. More information is available at the City of Port Angeles Web site.

Cleanup Activities

Ecology and Rayonier are currently focused on defining the extent of contamination and evaluating possible cleanup remedies.  This information will help in planning the final cleanup actions.  For detailed information about cleanup activities, please visit the Site Cleanup page.
 
Although the extent of contamination is still being investigated, two partial (interim) cleanup actions have already been completed.   

• In 1993, Rayonier removed 2.3 million-gallon fuel tank and 1,500 cubic yards of contaminated soil.
• In 1998, hydraulic oil and polychlorinated biphenyls (PCBs) were removed from the west bank of Ennis Creek.

Photos and more information on these partial cleanups can be found in the Interim Action Report (March 2003).
