Which code provides guidance for corrosion control of underground storage tank systems through cathodic protection?

• A. RP0285
• B. SPO169
• C. CPT2020
• D. NSF61

Answer: (A)

The correct answer is RP0285, as this code specifically relates to the design, installation, and maintenance of cathodic protection systems for underground storage tank (UST) systems. RP0285 is developed by the National Association of Corrosion Engineers (NACE) International and serves as a standard for protecting these structures from corrosion, which is critical for improving their longevity and preventing environmental contamination. By following the guidelines laid out in RP0285, operators and engineers can effectively implement cathodic protection measures, such as the use of impressed current or sacrificial anodes, which are essential for mitigating the risks of corrosion that underground storage tanks face due to their exposure to soil and groundwater conditions. The other codes listed do not specifically address underground storage tank systems in the context of cathodic protection. For example, SPO169 and CPT2020 may cover other standards and practices relevant to corrosion control or testing, but they do not provide the targeted guidance necessary for UST systems. NSF61 is a standard relating to the health effects of drinking water system components, which is unrelated to corrosion protection measures.
