AMPP Releases Pipeline Corrosion Guidelines


The Association for Materials Protection and Performance recently published a guideline for pipeline safety that aligns with new regulations from by the U.S Department of Transportation’s Pipeline and Hazardous Materials Safety Administration.

AMPP’s "Guide 21569-2024, Guidance on Implementing Corrosion Control Methodologies to Align with New PHMSA Regulatory Procedures," was developed by Standards Committee SC 15 - Pipelines and Tanks to strengthen the safety of onshore gas transmission pipelines.

To respond to the PHMSA's revised Federal Pipeline Safety Regulations, AMPP's new guide reportedly offers a detailed map for pipeline operators to begin using corrosion control requirements for onshore gas transmission as required in Part 2 of the PHMSA Gas Mega Rule.

The PHMSA revisions cover several improved safety measures, such as improved repair criteria, integrity management, cathodic protection and management of change, all reportedly meant to reduce risks from pipeline corrosion and ensure compliance with current safety standards.

“I’m very proud to have served as Document Project Manager for this development team comprised of an incredible group of industry pipeline subject matter experts across the country,” said Kimberly-Joy Harris, a retiree from Enbridge Pipelines with more than 30 years leading pipeline integrity and corrosion programs and Vice Chair of the AMPP Board of Directors.

“Our main goal was to assist U.S. natural gas pipeline companies with a guidance document that aligns with the new PHMSA Regulatory Mega Rule requirements related to integrity management, repair criteria, cathodic protection, and management of change, all to prevent and reduce failures. In addition, this document will be very useful globally to assist pipeline companies with improving their integrity programs and reducing failures."

AMPP states that Guide 21569-2024 will help United States gas transmission pipeline operators, while also providing insights for international counterparts that want to improve their corrosion control measures.

According to AMPP, this guide came from the industry's need for a stronger approach to align with the new corrosion control, operations, maintenance and integrity management PHMSA regulations that went into effect for transmission pipelines placed into service after Feb. 24, 2024.

The guide reportedly provides practical strategies for utilizing these requirements and leverages established practices to protect pipeline assets.

"Our project committee members and AMPP staff members did an amazing job working with the team through this process, and we were pleased to complete this project in record time, less than one year from initiation to publication,” Harris said.

Final Ruling

In August 2022, the PHMSA announced the final rule in order to strengthen the safety and environmental protection of more than 300,000 miles of onshore gas transmission pipelines. The rule was transmitted to the Federal Register on Aug. 4 of that year.  

According to the PHMSA’s release, the rule was first initiated over a decade ago and incorporated lessons learned through the investigation of the San Bruno gas transmission pipeline explosion in 2010, which resulted in the death of eight people and injuries to more than 60 others. The final rule established standards for identifying threats, potential failures and worst-case scenarios from an initial failure through conclusion of an incident.

Based on recommendations made by the National Transportation Safety Board, the updated rule established the following:

  • Imposes new Management of Change process requirements to, for example, avoid a situation like the San Bruno incident where a substandard segment of pipe was substituted without proper authorization;
  • Strengthens Integrity Management requirements, including identifying and evaluating all potential threats to pipelines;
  • Bolsters corrosion control standards to include surveys for interference of corrosion protection, internal and external corrosion monitoring, and corrosion protection testing; and
  • Institutes new requirements for inspections after extreme weather events; and expands criteria and expedites timelines for pipeline repairs.

Originally published in a 2011 Advanced Notice of Proposed Rulemaking, the final rule reportedly concluded a trio of pipeline safety rules following PHMSA’s 2016 proposed rulemaking for gas transmission and gathering pipelines.

Additionally, the administration issued a 2019 gas transmission final rule to address a number of congressional mandates and safety recommendations, as well as a 2021 final rule that significantly expanded the scope of safety and reporting requirements for more than 400,000 miles of previously unregulated gas gathering lines.

The PHMSA reported that the final rule also marked a milestone of the completion of three of the six measures in the U.S. Methane Reduction Action Plan. The final rule document can be read here.
