To the integrity engineers and inspectors out there: How has the evolution of ECDA (External Corrosion Direct Assessment) standards changed the way you approach field verification? I’d be curious to hear your experiences in the comments.

NACE RP0285 (later updated and designated as ) stands for Standard Practice: Corrosion Control of Underground Storage Tank Systems by Cathodic Protection .

Ideal for corporate environments requiring multi-user licenses for engineering teams.

The standard explicitly addresses a wide range of systems, including existing bare and coated mild steel tanks, new coated mild steel tanks, and all associated metallic piping and flexible connectors. It covers tanks used to contain oil, gas, and water.

The standard provides best practices for designing a CP system tailored to USTs, taking into account factors like soil resistivity, coating quality, and the presence of interfering structures. It distinguishes between galvanic (sacrificial anode) systems and impressed current systems , providing guidance for each.

Many reputable online standards retailers are authorized to sell NACE publications. These include: To the integrity engineers and inspectors out there:

Proper installation is critical to prevent system failure. NACE RP0285 outlines procedures for backfilling anodes, routing cables, and making secure electrical connections. It also addresses the threat of stray DC currents—often caused by nearby transit systems or welding equipment—which can accelerate localized corrosion if not properly bonded or mitigated. 4. Operation and Maintenance (O&M)

Guidelines for both galvanic (sacrificial anode) and impressed current cathodic protection (ICCP) systems.

Cathodic protection is not a "set-and-forget" technology. The standard mandates structured testing intervals to verify system health: It covers tanks used to contain oil, gas, and water
