Analysis of Natural Gas Transmission Pipeline Releases and Mitigation Options for Pipeline MAOP Reconfirmation

The objective of this report is to analyze the high-level impact of natural gas transmission pipeline MAOP reconfirmation as outlined in the Pipeline and Hazardous Materials Safety Administration (PHMSA) “Safety of Gas Transmission and Gathering Pipelines Noticed of Proposed Rulemaking” (NPRM), issued by PHMSA and published in the Federal Register on April 8, 2016. P-PIC’s analysis provides an overview of the potential natural gas releases connected to aspects of the NPRM and reviews calculations and mitigation options outlined in the PHMSA Preliminary Regulatory Impact Analysis and the M.J. Bradley & Associates report “Pipeline Blowdown Emissions and Mitigation Options,” prepared for the Environmental Defense Fund and the Pipeline Safety Trust in June 2016.
