The Resource Conservation and Recovery Act (RCRA) and Oil Pollution Prevention Act (OPPA) (40 CFR 112) are the primary regulations governing petroleum, oil, and lubricant (POL) storage tanks and spills management. These regulations protect the environment and the nation's navigable waters and natural resources from the potential hazards of a leakage from Aboveground Storage Tanks (AST) and Underground Storage Tanks (UST). Under these regulations, ASTs and USTs must be equipped with secondary containment, cathodic/corrosion protection, leak detection systems, and monitoring systems.
