Owens Brockway Glass Container- Johnson Lake 2086

Summary Information
(last updated on: 4/19/2021 1:47:58 PM)
[4/19/2021 VCP/Landes]: Ownens-Brockway conducted environmental cleanup of Johnson Lake and shoreline soil in 2014. Johnson Lake (ECSI #2086) is currently in long-term monitoring, in accordance with the 2012 Operations and Maintenance Plan. The next cap inspection and fish tissue study is planned for Summer 2022.

See ECSI 2086 for additional information on Johnson Lake.

Elevated levels of PCBs were identified in Johnson Lake in the 1994/95 sediment investigation of the Columbia Slough. Johnson Lake is located immediatelely north of and partially owned by Owens Brockway Glass Containers. Subsequent investigations identified PCBs in adjacent soil on the Owens property and elevated levels of PCBs throughout the lake sediment with higher concentrations locations on the southern shoreline. Elevated concentrations of metals and PAHs were also detected in the portion of the lake receiving stormwater runoff and historical settling pond overflow from the Owens facility.

In 2009/2010 Owens removed PCB-contaminated soil and created a swale for stormwater detention in the impacted area. In 2011/2012 Owens placed a minimum 6-inch cap of clean sand/sediment over the majority of the lake sediment. As part of Owens' Consent Judgment with DEQ, they settled their liability for the site's contribution to sediment contamination in the Whitaker Slough.

A Certification of Completion was filed with the court in January 2014. DEQ issued a no further action determination for this site in February 2014.

In 2017, Owens-Brockway conducted a cap inspection and fish tissue study to evaluate changes in PCB concentrations in fish. The cap inspection indicated the cap remains in place and is performing well. Native vegetation has regrown around the edge of the lake. The concentrations of PCBs in fish tissue in Johnson Lake were lower in 2017 than they were in 2004. However, the concentrations remain above human consumption risk based criteria of 0.39 micrograms per kilogram (µg/Kg). The average PCB concentrations decreased from 260 µg/Kg in 2004 to 106 µg/Kg in 2017.
