Dear Mr. McMenamin:
Your letter of June 25, 1981, requests that we amend §192.719(a)(2) to refer to §192.241 rather than 192.243 so that the exceptions from the requirement for nondestructive testing of new girth welds will apply to nondestructive testing of tie-in welds made when a damaged segment of a transmission line is cut out and replaced.
The request is supported by several arguments in favor of the suggested rule change, one of which challenges the basis for an "Advisory Bulletin No. 75-11." We have reexamined the basis for this interpretation and found the interpretation invalid. As a result, a new interpretation of §§192.719(a)(2) and 192.241(b), which supersedes the earlier one, is enclosed.
This new interpretation declares that the exceptions under §192.241(b) were intended to apply to tie-in welds made in repairing damaged pipe sections. Because of the significance of this action, the interpretation will be published in the Advisory Bulletin. We also believe that changing the rule as you suggest would clarify this issue and eliminate the need for an interpretation. Therefore, we will schedule a rulemaking action to so amend §192.719(a)(2).
We appreciate your concern for correct application of the Federal pipeline safety standards.
Sincerely,
Melvin A. Judah
Acting Associate Director for
Pipeline Safety Regulation
