Above Ground Storage Tank Regulations
Above ground storage tank (AST) regulations occur at both the federal and state/local level, so it’s important to ensure that tank owners and operators understand these individual regulations or hire a tank contractor
that does. Most ASTs must meet U.S. EPA’s Spill, Prevention, Control, and Countermeasure (SPCC) requirements, and there may be additional state or local regulations that help protect people and the environment. Your state agency can educate you on any additional requirements.
Below are some standard regulations that tank owners and operators
should keep in mind:
Secondary Containment Requirement
All ASTs should have a secondary containment area that holds in spills and also allows for easier leak detection. The containment area must hold 110% of the tank’s contents plus additional precipitation, and its materials must be impermeable. Manual sump pumps should be used to collect the extra rain water that may accumulate in the containment area, and the rainwater should be inspected for any petroleum or chemicals.
ASTs should be monitored regularly to confirm that the tank is in good condition. If the secondary containment area is constructed of more permeable materials, then tank inspections should be more frequent. Tank inspections
should include the tank foundation, connections, walls and piping systems.
Out of Service Tanks
If tanks are out of service for a year or more, many states require that the tank be maintained and monitored, declared inactive or removed completely. Inactive tanks must have all substances removed and then the tank must be cleaned, secured and clearly labeled as “Out of Service.”
