On December 10, 2011 an equipment failure on a diesel tank in the basement of Stanley Hall on the University of California, Berkeley campus resulted in spill of 1,650 gallons of diesel fuel. Clean-up crews recovered 799 gallons of diesel from the Stanley Hall basement. The spill released approximately 850 gallons of diesel to the environment through a culvert that discharges to the adjacent North Fork Strawberry Creek. Oil spill response teams recovered approximately 187 gallons of diesel from the creek and surrounding environment. Active clean-up efforts in Strawberry Creek were concluded successfully on January 13, 2012, with agency sign-off on the clean-up occurring on January 31, 2012.
