Federal Way park set to reopen after diesel fuel spill

Crews have finished cleaning up a diesel fuel spill at Dash Point State Park in Federal Way, allowing for the day-use area to reopen to the public Saturday.

The area has been closed since April 30. The night before crews discovered that diesel fuel had leaked from a 300-gallon tank owned by a contractor working for the state Department of Transportation. The contractor was working on the F.B. Hoit Bridge along State Route 509, which runs through the park, the state Department of Ecology reported today.

Most of the leaked fuel soaked into the soil. Some trickled into a creek, which empties into the Puget Sound. A sheen from the spill dissipated later April 30.

Cleanup crews removed 250 tons of potentially damaged soil, asphalt, cubs and rip rap, then replaced them with clean materials. A contractor cut through and repaired small areas of parking lot and road to access the contaminated locations.

Crews also removed trees and vegetation along Thames Creek. New plants will be planted next week.

The day-use portion of Dash Point State Park is open from 8 a.m. to 9 p.m.
