On Sunday, a sinking tugboat in Richmond began leaking oil into the surrounding water. And on Saturday evening, a fuel leak at UC Berkeley's Stanley Hall spilled 1,700 gallons of diesel, with some of it reaching the San Francisco Bay.
According to ABC, the spill was discovered by a UC Berkeley police officer who noticed an odor coming from Strawberry Creek at about 7 p.m. on Saturday night. The source was traced to the basement of the UC Berkeley hall.

"We know that we had some 1700 gallons of diesel fuel spilled within the building," said UC Environmental Health and Safety officer Mark Freidberg to ABC. "And a smaller amount -- some fraction of that -- was released to the creek."
The spill occurred because of a malfunction in the tank that feeds fuel to the building's emergency generator in the basement. The fuel then made its way into Strawberry Creek through a series of pumps that drain water from the basement. From there, it traveled into the Berkeley Marina and the San Francisco Bay.
"The agencies are telling us that it was a very small fraction that made its way into the Bay, fortunately," said Freidberg.
According to KTVU, the spill was contained by 9 p.m., and emergency crews were able to seep up much of the spilled fuel using vacuums and absorbent material. Reportedly, a nearby Good Samaritan even constructed a barrier along the creek, pulling 20 gallons of fuel from the water, according to SFGate.
Stanley Hall was closed for the weekend as crews cleaned the area, but, according to CBS, was reopened on Monday morning at 7:30 a.m. in time for finals.
The incident at Berkeley was one of two spills that leaked oil into the Bay this weekend. On Sunday, a decommissioned Navy tug boat in Richmond also spilled oil into the surrounding water, according to CBS. The Examiner reported that the boat was slowly sinking when officials noticed a black discharge coming from the vessel. Officials surrounded the boat with a boom and are attempting to skim the oil from the water.
No wildlife has been affected by either spill so far, but officials are keeping a close eye on the area.
