In 2018, a midstream operator used an unverified 1996 version of RP0285 to design a tank farm CP system. They missed the updated requirement for permanent reference electrodes under each tank. After three years, multiple tanks showed insufficient polarization, leading to a $2.3 million emergency repair and an EPA enforcement action.

of cathodic polarization must be observed. This is measured by tracking the voltage decay between the instant-off potential and the completely depolarized native state of the steel structure. Key Sections of the Standard Practice nace rp 0285 pdf verified
The standard has undergone several revisions and a designation change: NACE Standard RP0285-2002 - ANSI Webstore
To mitigate these risks, the National Association of Corrosion Engineers (NACE)—now known as AMPP (Association for Materials Protection and Performance)—developed . This recommended practice, titled "Corrosion Control of Underground Storage Tank Systems by Cathodic Protection," serves as the definitive global standard for designing, installing, operating, and maintaining cathodic protection (CP) systems for USTs. In 2018, a midstream operator used an unverified
