Interpretation Response Details
June 24, 1975
Mr. John Searcy
Tennessee Public Service Commission
Cordell Hull Building
Nashville, Tennessee 37219
Dear Mr. Searcy:
This responds to your letter of June 10, 1975, referring to our opinion that "a violation of Section 192.63 occurs when a component which is not marked...is used in a pipeline..." You state to the contrary that a marking violation can never occur in light of our interpretation that "Section 192.63 does not require that markings be maintained after installation."
It does not follow that because markings need not be maintained after installation, Section 192.63 cannot be violated. Like the design requirements in Part 192, the marking requirement is one which must be met before a pipeline is placed in operation. It does not have continuing application thereafter. Still, because the regulations in Part 192 apply to pipeline facilities actually used in the transportation of gas, a person cannot be charged with a violation of Section 192.63 until a component not marked as required is placed in operation.
Strictly speaking, in the case of a violation of Section 192.63, Section 192.13 should also be included in stating the violation. That Section makes it clear that a person may not operate a pipeline unless all applicable requirements in Part 192 are met.
Sincerely,
Joseph C. Caldwell
Director
Office of Pipeline Safety
