The Weyerhaeuser boat ramp is located on the Chehalis River near Cosmopolis and serves as a staging area for oil spill response operations.

According to the Grays Harbor Geographic Response Plan, equipment can be staged at the nearby F Street Boat Launch in Cosmopolis (managed by Cosmo Specialty Fibers), which features a gravel ramp suitable for launching workboats to deploy collection and exclusion booms along this section of the river.
