Pipeline Safety: Miscellaneous Changes to Pipeline Safety Regulations

Summary: PHMSA is amending the pipeline safety regulations to make miscellaneous changes that update and clarify certain regulatory requirements. These amendments address several subject matter areas including the performance of post-construction inspections, leak surveys of Type B onshore gas gathering lines, qualifying plastic pipe joiners, regulation of ethanol, transportation of pipe, filing of offshore pipeline condition reports, and calculation of pressure reductions for hazardous liquid pipeline anomalies. The changes are addressed on an individual basis and, where appropriate, made applicable to the safety standards for both gas and hazardous liquid pipelines. Editorial changes are also included.
