Pipeline and Hazardous Materials Safety Administration June 22, 2005 – Federal Register Recent Federal Regulation Documents

The Office of Pipeline Safety (OPS) seeks public comments on two petitions for rulemaking filed by Arkema, Inc. The petitions request changes to the gas pipeline safety regulations to increase the design factor for new polyamide11 (PA-11) pipe and to allow use of PA-11 pipe for systems operating at up to 200 pounds per square inch gauge pressure (psig). These requested changes will allow the use of PA-11 pipe in gas pipelines in place of metal pipe.
