Cathodic Protection


Steel tanks equipped with a Cathodic Protection (CP) system require testing once every three years at a minimum. In addition, sites equipped with an impressed current system have a rectifier which requires inspection once every 60 days. Owner/operators may conduct the 60-day inspections, however, a certified CP tester is required for the three year test.


Requirements for Cathodic Protection System Testing: 


  • Access to the rectifier (if applicable).
  • Access to the protected structures (tanks, lines, etc.).
  • Site or products will only require down-time in the event the protected structures are located in a high-traffic area near the fuel dispensing area.
  • Typical test time: 30-45 minutes per tank.
