The US Environmental Protection Agency said today it is hitting the San Francisco Municipal Transit Agency with a $250,000 civil penalty for federal violations of the Clean Water Act and Resource Conservation and Recovery Act.
The Department of Justice, working on behalf of the EPA, lodged a proposed consent decree with the US District Court for the Northern District of California against the city and county of San Francisco for releasing at least 940 barrels of diesel fuel — some of which entered into Islais Creek, a tributary of the San Francisco Bay.
The proposed consent decree requires the city and county of San Francisco to pay the $250,000 penalty and requires SF Muni to implement a training program that will improve coordination and communication during future incidents of this nature. The consent decree is subject to a 30-day public comment period.
During late November and December of 2005, red dye diesel fuel was released from the Woods bus servicing facility, located at 1095 Indiana Street in San Francisco. The EPA estimates at least 39,000 gallons of fuel were released. The discharge of oil into Islais Creek and interference with the pump station were violations of the Clean Water Act.
An EPA investigation found that Muni staff failed to comply with federal regulations issued under the Resource Conservation and Recovery Act that governs the management of underground storage tanks. The EPA has asserted that SF Muni’s federal RCRA violations include:
- Disabling an audible alarm system intended to alert operators to an ongoing release of diesel
- Failure to respond to flashing yellow alarm lights triggered by tank sensor alarms in full alarm mode
- Failure to maintain a written log noting the status, source, or reason for alarms
- Failure to use fuel inventory controls to monitor and observe that it was losing fuel from, the tanks at a constant conspicuous rate
- Inadequate containment
- A known kink and bulge in a faulty, braided, flexible hose that ultimately failed
- Failure to timely notify authorities of the release
The spill had originated when a faulty hose ruptured and underground storage tanks overflowed. The released diesel fuel landed in a storm drain where heavy flows from a major December rain storm caused the storm drain to overflow to the stormwater line. The fuel then caused an interference with a San Francisco southeast wastewater treatment pump station. From there, some of the fuel spilled into Islais Creek, which drains into Central San Francisco Bay.
“Facility operators must pay rigorous attention to operational practices in order to protect the San Francisco Bay and our coastal resources,” Laura Yoshii, the EPA’s Acting Regional Administrator for the Pacific Southwest, said in a statement.
The city and county of San Francisco conducted remedial actions to clean up the spill in 2006 and has also taken initiative to evaluate its procedures and upgrade its facilities to prevent further spills. In addition to the work required by the consent decree, SF Muni has taken steps to decrease the likelihood of any future releases, including:
- Completing all spill prevention, control, and countermeasure requirements and including installation of adequate containment, and the preparation of spill prevention plans
- Replacing the piping in underground sumps
- Replacing the containment boxes under all diesel and gasoline dispensers,
- Repairing alarms
- Installing external alarms with light and horn notifications and a remote alarm monitoring system
- Establishing new procedures to monitor fuel inventory and provide MTA staff supervision for fuel deliveries
- Additional controls in order to quickly identify and respond to releases diesel fuel
