Aboveground Petroleum Storage Act (APSA)

​The purpose of the Aboveground Petroleum Storage Act (APSA) is to protect public health and the environment from potential contamination or adverse effects associated with unintentional releases from the aboveground storage of petroleum-based hazardous materials and wastes. APSA applies to facilities with a total storage capacity, at a single location or site, of 1,320 gallons or more of petroleum in aboveground tanks and containers that are 55-gallons in size and greater.



If your facility is located anywhere in Santa Clara County, other than the cities of Gilroy, Santa Clara, Palo Alto, Milpitas, or Sunnyvale, and your facility is subject to APSA, you must obtain an APSA Facility Permit from HMCD.

HMCD provides regulatory oversight by reviewing Aboveground Petroleum Storage Tank Facility Statements, reviewing and verifying Spill Prevention Control and Countermeasure (SPCC) Plans, and routine inspections of facilities with a total petroleum storage quantities at or above 10,000 gallons.
