Update on the Safety of Gas Transmission and Gathering Pipelines Rulemaking (known as the Mega-Rule)
Structural Integrity (SI) personnel have had significant involvement in the Gas Pipeline Advisory Group (GPAC) meetings focused on consideration of the proposed pipeline safety rule titled “Safety of Gas Transmission and Gathering Pipelines” (Notice of Proposed Rule Making April 8, 2016). The meetings produced several recommendations to the Pipeline and Hazardous Materials Safety Administration (PHMSA) that are likely to be included in the Final Rule. A key outcome of these meetings was that PHMSA has decided the Final Rule will be split into three sub-rule packages that will all be final rules to facilitate the rulemaking process:
- Maximum Allowable Operating Pressure (MAOP) reconfirmation, Material Verification, Expansion of Integrity Management Assessments Outside of High Consequence Areas (HCAs) and other related issues,
- Repair Criteria, Inspections Following Extreme Weather Events, Corrosion Control improvements, Management of Change; and
- Expansion of Part 192 regulations to include additional Gas Gathering Lines.
