Hi Class A/B UST Operator:
Are you confused about what to do and when regarding testing the equipment on your UST system? You’re probably not alone. Use this handy table to figure out which device needs testing and when. This table combines both the “older” UST rules plus some new ones your state UST agency probably recently adopted.
Disclaimer: Know that some states are more strict than Federal law so check with your local UST agency if you have questions. For instance, exactly which sumps must be tightness tested depends on what state you are in and what date mandatory sumps went into effect. Also, states vary as to who can actual perform each test. Again, check with your UST agency for details.
