Notice; criteria for class location change waivers.
Summary
This notice announces the availability of the criteria that the Office of Pipeline Safety (OPS) will use in considering waiver applications submitted by operators of natural gas pipeline segments that have experienced a change in class location. A class location change results from new construction in the vicinity of a pipeline segment and, in the absence of a waiver, triggers a requirement that the maximum allowable operating pressure be confirmed or revised. The criteria matrix provides information and guidance to pipeline operators concerning the specific pipe design and operating parameters within which OPS is likely to consider a class location waiver application to be consistent with pipeline safety.
