Crews are at the scene of a hazardous materials incident in the Altamont area of unincorporated Alameda County that has prompted a road closure this afternoon, authorities said. The California Highway Patrol received a report shortly after 10 a.m. about barrels of materials that were dumped in a creek along Altamont Pass near Carroll Road.

The report indicated that there were up to 55 gallons of materials spilled but that it was apparently not related to a traffic accident. CHP officials were not able to confirm details on the incident and said the U.S. Fish & Wildlife Service was handling it.
