Yolo County has over 200 facilities storing hazardous materials in aboveground storage tanks throughout the county.
Petroleum, when improperly managed and stored, can present health hazards and threaten the environment, particularly navigable waters and adjoining shorelines. To prevent harm to the public and the environment, the federal Oil Pollution Prevention regulation, promulgated under the authority of §311 of the Clean Water Act (CWA), sets forth requirements for prevention of, preparedness for, and response to oil discharges at specific non-transportation-related facilities. To prevent oil from reaching navigable waters and adjoining shorelines, and to contain discharges of oil, the regulation requires these facilities to develop and implement Spill Prevention Countermeasure and Control (SPCC) Plans andestablishes procedures, methods, and equipment requirements. The SPCC rule, as it is known, can be found in the Code of Federal Regulations, title 40, part 112.
Who Regulates Facilities Subject to the Aboveground Petroleum Storage Act?
Previously, the State Water Resources Control Board (SWRCB) and the Central Valley Regional Water Quality Control Board (CVRWQCB) administered the SPCC rule in Yolo County at tank facilities subject to the federal regulations. Environmental Health, the CUPA, during routine compliance inspections at tank facilities for other Unified Program elements, was required to verify that an SPCC plan had been prepared. If an SPCC plan had not been prepared, Environmental Health submitted a referral to the CVRWQCB for enforcement. Previous law also required a tank facility owner or operator to file a storage statement with the SWRCB and pay the fee specified in law to the SWRCB.
Assembly Bill 1130, the California Aboveground Petroleum Storage Act, was chaptered on October 13, 2007, and became effective on November 10, 2010. This bill transfers the authority and responsibility for administration of the Aboveground Petroleum Storage Act in Yolo County from the SWRCB and the CVRWQCB to Environmental Health, the CUPA. Environmental Health is responsible for integrating this new program into the overall CUPA program, and conducting inspections and enforcement at regulated tank facilities. Fees that the SWRCB had previously collected from tank facilities fund the grant, and it will fund the implementation activities necessary for Environmental Health to integrate the Aboveground Petroleum Storage Tank Inspection and Enforcement program into the CUPA program.
Who is Subject to the Aboveground Petroleum Storage Act?
Facilities having an aggregate petroleum storage capacity of 1,320 gallons or greater in containers 55 gallons and larger (with exception to the tanks exempted by Section 25270.4.5 (b) of the Aboveground Petroleum Storage Act) are subject to the Aboveground Petroleum Storage Act.
Are all AST Facilities Required to Prepare a SPCC Plan?
Spill Prevention Control and Countermeasure (SPCC) Plans are required for all aboveground petroleum storage tank facilities with a single tank greater than 1,320 gallons or a cumulative storage capacity (including tanks and containers) of greater than 1,320 gallons. An SPCC plan must follow the sequence outlined in 40 CFR 112 beginning with Section 112.7(a).
