UST Cathodic Protection Repair and Testing

If you’re an owner or operator of an underground storage tank (UST) in Washington, you’re no doubt aware of the requirement to test your tank’s cathodic protection (CP) system every three years to ensure that it’s functioning properly.

You may not, however, be aware of the required testing cycle should you need to refit or repair your CP system. According to Washington state regulations, a CP system must be tested immediately following the repair and once again within six months of the repair. If the CP system passes both tests, owners and operators may then resume the testing cycle of every three years thereafter. Owners and operators are also required to keep records of the last two CP tests conducted.

If you’re an owner of a UST in another state, similar requirements may apply to you. Check with the appropriate regulatory authority in your state.
