Work Begins on Cleanup Project at Skagit Regional Airport

Burlington – The Taxiway F cleanup project began today at Skagit Regional Airport. Clear Creek Contractors, Everett, is the contractor for the $1,256,471 Port of Skagit project.

The cleanup site includes an aircraft hangar and adjacent area near Taxiway F at the western edge of the airport, and covers 2.2 acres. The hangar and surrounding area were used for crop-dusting operations between 1978 and about 2000, which included storage of chemicals for crop dusting. The port discovered stained soils at the site in 2000 and began the process of soil and groundwater investigation. Crop-dusting operations released several different chemicals including pesticides, fungicides, and herbicides in the area where chemical mixing and aircraft loading and storage occurred. The most commonly detected product is Thiodan, which is the trade name for endosulfan.

The cleanup work will include removing the contaminated soil to a permitted facility off-site; backfilling the excavations with clean, imported fill material; and restoring wetland and forest vegetation. The contractor expects to have the job substantially complete by December, using a crew of approximately six workers.

The Department of Ecology and the Port of Skagit have entered into a legal agreement called a consent decree. Under this decree, the port will clean up the site as described in the decree’s Cleanup Action Plan and provide opportunities for public involvement as described in the Public Participation Plan. The Cleanup Action Plan was prepared using information from the Final Remedial Investigation/Feasibility Study.
