I received a minor non-conformance in my last audit "evidence of the utility interruptions being detailed within the current contingency plan revised in Feb 2022 could not be found". I'm struggling with the root cause on my 3L5Y. We've had this contingency plan in place for several years now, and it has been updated as required, and testing completed. We had the utilities companies listed on the contingency plan but we didn't have it spelled out in enough detail. We thought we had met the requirements. Any suggestions on the root cause wording for systemic, detection, and specific?
