Pipeline Safety: Periodic Updates to Pipeline Safety Regulations (2001)

Summary: This final rule is part of an effort by RSPA to periodically update the pipeline safety regulations. This rule incorporates the most recent editions of the voluntary consensus standards and specifications referenced in the Federal pipeline safety regulations to enable pipeline operators to utilize the most current technology, materials, and industry practices in the design, construction, and operation of their pipelines. This rule also increases the design pressure limitation for new thermoplastic pipe, allows the use of plastic pipe for certain bridge applications, increases the time period for revision of maximum allowable operating pressure after a change in class location, clarifies welding requirements, and makes various other editorial clarifications and corrections. This final rule does not require pipeline operators to undertake any significant new pipeline safety initiatives.
