Study Explores Port Angeles Sediments

Samples taken from Port Angeles Harbor show toxic contamination spread throughout the marine environment near the former Rayonier Mill site.

Yesterday, the Department of Ecology released a report that summarizes data collected about contamination on part of the mill site.

The Marine Data Summary Report details the amount and type of contamination in the marine portions of the study area. It includes data from earlier studies, such as Ecology’s Port Angeles Harbor Sediments Study (completed in 2012). This report, along with data about the upland portion of the study area, will help Rayonier Advanced Materials develop a plan for cleaning up the study area. The study area includes the 75-acre former mill property (upland) and about 1,300 acres of marine environment.

The amount and type of contamination varies across the marine portion of the study area. The highest levels of contamination are in the eastern part of the log pond area and near the mill dock. These are also the areas where sediments were the most toxic to marine organisms.

Ecology released Rayonier’s upland data report in 2013. It showed that the amount and type of contamination varies across the upland. Past partial cleanups removed more than 30,000 tons of contaminated soil, leaving only lower levels of contamination across much of the upland.

In the upland, Rayonier found PAHs, dioxins and furans, or toxic metals in soil, groundwater and surface water. In subsurface soil, defined as deeper than 2 feet, the study found PAHs and PCBs. Some PCBs also were found at low levels in groundwater. Rayonier also found some areas of low and high pH in groundwater. The pH scale measures a material’s acid or alkaline content.

The Rayonier study area is being cleaned up under an agreed order, which is a legal agreement to conduct a remedial investigation and to evaluate cleanup options. The remedial investigation evaluates the extent of contamination. A document called a feasibility study details cleanup options.

Rayonier Advanced Materials is on schedule with its agreed order tasks. The company’s next deadline is Feb. 9, 2015, when a draft analysis of cleanup options is due.

Ecology will hold a public comment period in 2015 when Rayonier’s analysis of study area cleanup options is available, in addition to the marine and upland data reports.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
