How were the gas transmission pipeline regulations revised to reflect the alternative MAOP requirements?
The rule adds a new section 49 CFR 192.620 in Subpart L – Operations. This new section explains what an operator is required to do to operate at a higher MAOP than formerly allowed by the design requirements. Among the conditions set forth in new 192.620 is the requirement that the pipeline be designed and constructed to more rigorous standards. These additional design and construction standards are set forth in two additional new sections (49 CFR 192.112 and 192.328) located in Subpart CPipe Design and Subpart GGeneral Construction Requirements for Transmission Lines and Mains, respectively. In addition, the rule makes necessary conforming changes to existing sections on incorporation by reference (49 CFR 192.7), change in class location (49 CFR 192.611), and maximum allowable operating pressure (49 CFR 192.619).
