Crews using vacuum trucks spent Friday cleaning up diesel fuel that spilled in Steilacoom, the state Department of Ecology reported.
Ecology officials were notified about 10 p.m. Thursday of fuel in storm drains and ditches. Investigators tracked the source of the fuel to a residence on Nisqually Avenue. The cause of the spill remained unknown Friday afternoon, Ecology spokeswoman Linda Kent said.
Officials said a small amount of diesel sheen may occur at the outfall near the landing for the Steilacoom-Anderson Island Ferry at 56 Union Avenue in Steilacoom.
