The EPA has mandated that Underground Storage Tank (UST) owners meet the following guidelines: 

Spill Prevention - Obtained by using a catchment basin attached to the fill pipe of each tank. 

Overfill Protection - Obtained by using one of the following for each tank: Automatic Shut Off Device, Overfill Alarm, and Ball Float Valve. 

Corrosion Protection - All underground steel tanks and piping routinely containing product must be protected from corrosion. This can be accomplished by using non-corrosive materials or by installing impressed or sacrificial cathodic protection systems to steel tanks, steel lines, steel swing joints, and steel flex connectors. 

Leak Detection - In general, most tanks and lines must have some form of leak detection. This can be accomplished by using one of the following: Automatic Tank Gauging, Vapor Monitoring, Secondary Containment with Interstitial Monitoring, Groundwater Monitoring, Statistical Inventory Reconciliation (SIR), or any other method approved by the regulatory authorities. 

Financial responsibility - As a UST owner you must be able to demonstrate your ability to pay for damages that could occur if your UST leaks. 

Visit the EPA Office of Underground Storage Tanks website for more information. 

You may also have specific state/local guidelines that must also be met.
A Tanknology representative, or a representative within your state environmental office, can discuss with you in further detail how the regulations will affect you.
