The Spill Prevention Control and Countermeasures (SPCC) Rule prevents facilities from discharging oil into the nation's waters. Facilities must utilize secondary containment measures, proactively prevent oil spills and plan for rapid oil spill response.

Secondary containment systems hold spills from containers, drums, totes and tanks. Maintaining secondary containment systems prevents spills from becoming reportable discharges.

Facilities with threshold quantities of hazardous chemicals must assess their processes and establish a program to safely manage those processes and chemicals. Plans must focus on proper operating procedures as well as emergency response procedures.

Aboveground Storage Tanks (ASTs) require routine maintenance, testing and inspections to ensure that bulk fluids storage will not cause leaks, spills or chemical releases.
