Cathodic Protection Testing

Corrosion Protection

All cathodic protection systems:

Owners and operators must have a periodic test conducted by a qualified cathodic protection tester to make sure the cathodic protection system is adequately protecting the UST system. This test must be conducted:

  • Within six months of installation
  • At least every three years after the previous test
  • Within six months of any repair to the UST system

Owners and operators must make sure the cathodic protection tester is qualified to perform the test and follows a standard code of practice to determine that test criteria are adequate. If any test indicates your tanks are not adequately protected, you must have a corrosion expert examine and fix your system.


Keep records of the most recent two cathodic protection tests.

Impressed current cathodic protection systems:

Owners and operators must inspect the rectifier at least every 60 days to make sure that it is operating within normal limits.

This inspection involves reading and recording the voltage and amperage readouts on the rectifier. Owners and operators can perform this periodic inspection.

Owners and operators need to make sure the corrosion expert provided the rectifier’s acceptable operating levels so owners and operators can compare the readings to make sure they are within acceptable operating levels. If readings are not within acceptable levels, contact a corrosion expert to address the problem.

Keep records of at least the last three rectifier readings.
