Protocol Item D.02

Verify that the operator identifies and collects adequate data to support ECDA pre-assessment. [NACE RP0502-2002, Section 3.2]

Verify that the operator conducts an ECDA feasibility assessment by integrating and analyzing the data collected. [NACE RP0502-2002, Section 3.3]

1. A minimum of 2 complementary tools must be selected such that the strengths of one tool compensate for the limitations of the other tool. (Note: The operator must consider whether more than two indirect inspection tools are needed to reliably detect corrosion activity.)
2. Tools are able to assess and reliably detect corrosion activity and/or coating holidays.
3. Verify that the operator documents the basis for its tool selection.
4. If the operator utilizes an indirect inspection method not listed in NACE RP0502-2002, Appendix A, verify that the operator justifies and documents the method's applicability, validation basis, equipment used, application procedure, and utilization of data. [§192.925(b)(1)(ii)]

Verify that the operator identifies ECDA Regions based on the use of data integration results applied to specified criteria. [NACE RP0502-2002, Section 3.5]

Verify that the operator applies more restrictive criteria when conducting ECDA for the first time on a covered segment. [§192.925(b)(1)(i)]
