Tank Facilities with a total storage capacity of ≥ 1,320 gallons* and ≤ 10,000 gallons of oil, with limited or no oil releases, are considered "Qualified Facilities" under the federal SPCC rule. There are two types of qualified facilities, Tier I and Tier II.
Qualified Facilities may use ready-made templates to develop their SPCC Plan and may self-certify their SPCC Plan.
Tier I facilities may prepare and self-certify their own SPCC plan. U.S. EPA SPCC Plan Template - Tier I Qualified Facilities.
Tier II facilities may also prepare and self-certify their own SPCC Plan. SPCC Plan Template - Tier II Qualified Facilities.
Large Tank Facilities, with a storage capacity of more than 10,000 gallons of oil must use a Professional Engineer to cerfity the SPCC Plan. The USEPA provides resources and guidance on their website.
