2137-AF29 201810 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2137 Pipeline and Hazardous Materials Safety Administration PHMSA 2100 Department of Transportation DOT Pipeline Safety: Class Location Requirements

This rulemaking regards existing class location requirements, specifically as they pertain to actions operators are required to take following class location changes. Operators have suggested that performing integrity management measures on pipelines where class locations have changed due to population increases would be an equally safe but less costly alternative to the current requirements of either reducing pressure, pressure testing, or replacing pipe.

Section 5 of the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011 required the Secretary of Transportation to evaluate and issue a report on whether integrity management requirements should be expanded beyond high-consequence areas and whether such expansion would mitigate the need for class location requirements. PHMSA issued a Notice of Inquiry on this topic on August 1, 2013, and issued a report to Congress on its evaluation of this issue in April 2016. In that report, PHMSA decided to retain the existing class location requirements but noted it would further examine issues related to pipe replacement requirements when class locations change due to population growth. PHMSA noted that it would further evaluate the feasibility and appropriateness of alternatives to address this issue following publication of the final rule titled "Pipeline Safety: Safety of Gas Transmission Pipelines" (Docket No. PHMSA-2011-0023; RIN 2137-AE72). In line with that intent, section 4 of the Protecting Our Infrastructure of Pipelines and Enhancing Safety Act of 2016 requires PHMSA to provide a report to Congress no later than 18 months after the publication of the Gas Transmission final rule that reviews the types of benefits, including safety benefits, and estimated costs of the legacy class location regulations. Therefore, PHMSA is initiating this rulemaking to determine whether the performance on integrity management measures, or other safety measures, on pipelines where class locations have changed due to population increases would be an equally safe but less costly alternative to the current class location change requirements.

Congress established the current framework for regulating the safety of natural gas pipelines in the Natural Gas Pipeline Safety Act of 1968 (NGPSA). The NGPSA provided the Secretary of Transportation the authority to prescribe minimum Federal safety standards for natural gas pipeline facilities. That authority, as amended in subsequent reauthorizations, is currently codified in the Pipeline Safety Laws (49 U.S.C. sections 60101 et seq.).

In this rulemaking, PHMSA will identify possible alternatives to the current class location requirements, specifically those requirements causing operators to reduce pressure, pressure test, or replace pipe when class locations change in areas due to population increases. One such alternative, as suggested by certain members of the industry, could include the performance of integrity management measures on affected pipelines.

PHMSA believes there is no cost to this rulemaking action, but we will solicit further information on the costs and benefits of the current class location requirements as they pertain to class location changes, as well as the costs and benefits of any alternatives.

PHMSA is evaluating whether the performance of integrity management, or other alternatives, in lieu of the current regulatory requirements for reducing pressure, pressure testing, or replacing pipe when class locations change due to population growth, will increase, decrease, or maintain the current level of risk. PHMSA notes that while certain alternatives to the current regulations might allow for an equivalent level of risk, there is a potential for greater consequences in an area where a class location has changed due to population increases along the pipeline.
