If you are the owner of an above ground storage tank containing petroleum product with a storage capacity of at lease 1,320 gallons, you must prepare a Spill Prevention Control and Countermeasure (SPCC) Plan. This Plan is to be kept on site at all times and updated every 5 years.
Above Ground Storage Tank systems are required to be reported in CERS as part of a facility HMBP. See below for templates and refer to the CERS page for information on how to report your AST.
