Comment Period

Boeing Auburn

Draft documents available for public comment

April 26, 2021 - June 18, 2021, 11:55 p.m.

We invite you to review and comment on draft documents for Boeing's facility at 700 15th St. SW in Auburn, Washington.

The Boeing Company owns and operates the Boeing Auburn plant, which makes parts for commercial aircraft. Boeing treated and stored hazardous waste at its Auburn facility and used trichloroethlyene (TCE), a liquid chemical, to clean metal airplane parts. TCE leaked into soil and groundwater through decades of use. Groundwater contamination extends off the Boeing property. Boeing no longer uses TCE at the facility.

Resolved groundwater cleanup standard dispute 

Boeing agrees to clean up the contamination. Orignally they disagreed with us on the water cleanup standard, however, Boeing has now agreed to use the stricter water cleanup standard. 

This dispute is not a required part of this public comment period, but you may still submit comments to reflect your opinion on this subject.
