WILLARD BAY -- Authorities are cleaning up a diesel fuel spill at Willard Bay State Park.
The entire park is closed, the north side because of the spill and the south side for winterization work.
Deena Loyola, spokeswoman for Utah State Parks, said park officials are working to reopen the south side within a few days. The north side will remain closed for an undetermined period.
The spill occurred in a campground and day-use area in the north section of the park, Loyola said.
Because the park doesn't receive too many visitors this time of the year, only a few campers had to be evacuated when the leak was discovered, she added.
Greg Hardy, a spokesman for Chevron Oil, owner of the pipeline, said company officials noticed a drop in pressure in the line about 2:30 p.m. Monday. Chevron confirmed the leak and mobilized emergency and cleanup crews.
Workers placed flotation booms in a retention pond to try to collect the spilled fuel. Absorbent pads are also being used to soak up the fuel, and vacuum trucks are sucking up contaminated water for treatment, Hardy said.
Willard Bay encompasses about 10,000 acres.
Several environmental response vehicles were also at the scene of the cleanup Tuesday afternoon.
Hardy said the pipeline, which was installed in 1950, begins at a Chevron refinery in Salt Lake City and ends at a station in Burley, Idaho.
Hardy said he did not know how much fuel spilled or how long cleanup may take.
The diesel fuel did not reach Willard Bay and was contained in the pond, Loyola said.
Two beavers covered in fuel were treated Tuesday afternoon at the Wildlife Rehabilitation Center in Ogden, said Phil Douglass, state Division of Wildlife Resources conservation outreach manager for Northern Utah.
The beavers were cleaned by rehabilitation center employees with hazmat pads donated by the Ogden Fire Department and were bathed in Dawn dishwashing liquid, Douglass said.
There are also fish in a wetland adjacent to the retention pond, but it doesn't appear they were affected, Douglass said. The DWR will continue to investigate the spill to determine any future harm to wildlife.
