PORTOLA VALLEY (CBS SF) — Authorities have shut down an Interstate Highway 280 on-ramp near Portola Valley this morning as a hazardous materials team examines two mysterious containers found there Monday morning.
Cal Fire Battalion Chief John Pearl said a crew performing roadside cleanup found two plastic 55-gallon drums in the area of the Alpine Road on-ramp at about 8:20 a.m.
Cal Fire, Santa Clara County fire and the Woodside Fire Protection District were called to the scene to investigate what is inside the containers.
It appears the drums might contain some type of oil, Pearl said. There has been very little leakage, and none has spilled into any waterways, he said.
The on-ramp has been shut down, and Pearl did not yet have an estimate for when it would reopen.
