The Pipeline and Hazardous Materials Safety Administration is seeking comment on a Petition for Declaratory Order (Petition) requesting PHMSA issue an order regarding requirements for baseline integrity assessments.
PHMSA proposes to modernize and to clarify the anomaly response criteria in the Federal pipeline safety regulations for gas transmission and hazardous liquid pipelines. Driven by twenty years of technological development, modern engineering concepts allow operators to identify, schedule, and remediate pipeline anomalies more effectively and in a less costly manner. PHMSA proposes incorporating these improved safety practices into its regulations by finalizing certain safety improvements advanced in recent rulemakings for gas transmission pipelines and extending those changes to hazardous liquid pipelines. In addition, PHMSA proposes certain non-substantive revisions to its gas and hazardous liquid repair regulations to improve compliance.
Breakout tanks are used to "relieve surges in a hazardous liquid pipeline system" or to "receive and store hazardous liquid transported by a pipeline for reinjection and continued transportation by pipeline." American Petroleum Institute Standard 653 (API Std 653) sets industry standards for the inspection, repair, alteration, and reconstruction of aboveground storage tanks. PHMSA currently incorporates the 3rd edition of API Std 653 (issued December 2001) by reference into its regulations for breakout tanks. In this rulemaking, PHMSA is proposing to update its regulations for breakout tanks to incorporate the 5th edition of API Std 653 (issued November 2014) by reference. As a key part of this, PHMSA is proposing to authorize the use of risk-based inspection (RBI) procedures for establishing the inspection intervals of in-service breakout tanks.
This NPRM proposes to remove the exclusion for welders or welding operators qualified by nondestructive testing from welding on compressor station pipe and components.
This NPRM proposes to increase the monetary threshold for Operator Identification Number notifications for certain construction and maintenance tasks on gas and hazardous liquid and carbon dioxide pipeline facilities. PHMSA is also proposing to adjust inflation adjustment procedures to provide a mechanism for updating these thresholds on an annual basis.
This NPRM proposes to extend the annual report deadline for operators of gas distribution pipelines, gas transmission pipelines, regulated gas gathering pipelines, Type R gas gathering lines, underground natural gas storage facilities, and liquefied natural gas facilities. This NPRM also proposes to extend the National Pipeline Mapping System information submission deadline for operators of gas transmission and liquefied natural gas facilities. Annual reports for gas pipeline and gas pipeline storage facilities would be due on June 15, consistent with existing requirements for hazardous liquid pipelines.
PHMSA proposes to clarify that right-of-way patrol requirements are technology neutral, and that operators can use remote sensing technologies, such as unmanned aerial systems and satellites, for complying with gas transmission, hazardous liquid, and carbon dioxide pipeline rights-of-way patrolling requirements.
PHMSA proposes to revise the definition of property damage for determining when a release from a gas, hazardous liquid, or carbon dioxide pipeline facility meets the definition of a reportable incident or accident, including for immediate notifications to the National Response Center. This NPRM addresses comments received in response to a now-withdrawn direct final rule covering the same topic.

These amendments are intended to maintain consistency with the latest international standards and regulations, and to reduce costs to entities or individuals within the United States or to otherwise lower the cost of regulations on the United States economy.
PHMSA is publishing this ANPRM to solicit feedback on streamlining and modernizing the Agency's regulations as they relate to the transportation of hazardous materials integral to spacecraft payloads or components.
PHMSA is updating its regulations to allow operators to apply modern risk management principles in addressing the safety of gas pipelines affected by class location changes. Relying on an approach originally developed in the 1950s, PHMSA's regulations use class locations to provide an additional margin of safety in the design, construction, testing, operation, and maintenance of gas pipelines based on population density. When the class location of a pipeline changes due to an increase in population density, an operator may need to take certain actions to confirm or to revise the maximum allowable operating pressure of a segment. Because the methods traditionally used for that purpose do not account for modern risk management principles, PHMSA has granted special permits for more than two decades allowing operators to use an integrity-management-based alternative. This final rule adopts that `IM alternative' by regulation to provide operators with an additional method for confirming or restoring the maximum allowable operating pressure of certain eligible segments that experience class location changes.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) is publishing this advance notice of proposed rulemaking (ANPRM) to obtain stakeholder input on potential revisions to the Hazardous Materials Regulations (HMR) to facilitate the safe transportation of hazardous materials using highly automated transportation systems.

This proposed change will provide significant cost savings to gas transmission pipeline operators, eliminate ineffective regulations, and simplify current requirements.
PHMSA is proposing to revise the corrosion requirements in 49 CFR part 192 for gas distribution systems by replacing the 3-year reassessment interval with a 5-year reassessment interval following the replacement of pipeline segments or components in service lines.
