On October 1, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published three long-awaited final rules amending the federal pipeline safety regulations. The first rule amends the federal safety standards for gas transmission lines. The second amends the federal safety standards for hazardous liquid pipelines. The third updates procedures for issuing emergency orders. These rules are summarized below.
Safety of gas transmission pipelines
The gas transmission rule, commonly referred to as the “Mega Rule,” is the first in a three-part series of rules that PHMSA will be issuing to substantially revise the current federal safety standards and establish new requirements for gas pipeline facilities. This rule responds to congressional mandates and National Transportation Safety Board recommendations that arose from the investigation a 2010 gas transmission line incident in San Bruno, California. The rule adopts new requirements for verifying pipeline materials, reconfirming maximum allowable operating pressure (MAOP) and performing periodic assessments of pipeline segments located outside of high consequence areas (HCAs). The rule also amends the integrity management (IM) requirements, establishes requirements for reporting MAOP exceedances, for using inline inspection (ILI) launcher and receivers, as well as related recordkeeping requirements. The rule takes effect on July 1, 2020, but includes staggered compliance deadlines that extend as far out as 15 years.
- Materials verification. Operators will be required to conduct destructive and nondestructive tests to verify pipeline attributes when they do not have traceable, verifiable and complete records for such attributes in certain situations, such as MAOP reconfirmation, IM or repair requirements. The new requirements allow for collection of missing pipe attributes over time, whenever a pipeline segment is exposed for maintenance or repairs, until a minimum number of excavations are performed.
