Weaklend\nChief, Pipeline Safety Utilities Division\nArizona Corporation Commission\n1200 W. Washington Street\nPhoenix, AZ 85007\nDear Mr. Weaklend:\nThank you for your letter of July 29, 1992, regarding cathodic protection tests. You asked if a\npipeline's cathodic protection is acceptable if a test point on the pipeline meets one of the criteria\nin Appendix D of 49 CFR Part 192 but fails under another of the criteria.\nThe Part 192 standards relevant to your inquiry are §§ 192.463(a) and 192.465(a). Under §\n192.463(a), each cathodic protection system on a pipeline must provide a level of protection that\ncomplies with one or more of the Appendix D criteria or its equivalent. Section 192.465(a)\nrequires operators to test each pipeline under cathodic protection to determine if § 192.463(a) is\nmet.\nAs we apply these standards, an operator is in compliance with\n§ 192.463(a) as long as each point tested under § 192.465(a) meets any one of the Appendix D\ncriteria or its equivalent. No further test data are required if one of the criteria is met. In\naddition, the operator's corrosion control procedures under § 192.453 should, at a minimum,\nspecify the criterion used for each segment of pipeline.\nI apologize for the delay in answering your letter. For a prompt reply to any of your concerns,\nplease call Jim Thomas, Director, Southwest Region, at (713) 750-1746.\nSincerely,\nCesar De Leon\nDirector, Regulatory Programs\nOffice of Pipeline Safety\njt\n192.463/92-11-03","truncated":false,"body_characters":1512}
