In May of 2019 the Agency awarded JDH a contract to provide annual cathodic protection system assessment, engineered plans and specifications of previously identified repairs, and system optimization.
One recommendation from JDH is the installation of Remote Monitoring Units (RMU) at each cathodic system rectifier. Forty-five rectifiers were installed on the system in 1998, 40 rectifiers are currently operational. Rectifiers convert alternating current (AC) to direct current (DC) that is imp...
