Section 11-5-2-280.1-5 - INSTALLATION/REPAIR OF CATHODIC PROTECTION SYSTEMS
Section 11-5-2-280.1-5-5.2 - Impressed Current Systems

Anyone who is a MDEQ certified UST installer may install and/or repair an impressed current cathodic protection system. However, the design of an impressed current system must be accomplished by a corrosion expert. If the repair of an impressed current cathodic protection system results in the reconfiguration of any of the components of the system, then the reconfiguration must also be designed by a corrosion expert.

If the repair only involves the replacement of existing components, a corrosion expert does not need to "sign-off on such work. However, after any repair/alteration of the impressed current system is made, an evaluation of the cathodic protection survey must be conducted within six months of the repair. If the repair/alteration results in any of the conditions found in Section 7.2 of this document being met, the cathodic protection survey must be conducted/evaluated by a corrosion expert.
