A History of the PHMSA 192 Mega Rule

On September 9, 2010, a buried high-pressure natural gas line exploded in the City of San Bruno, California. On December 11, 2012, a natural gas pipeline in Sissonville, West Virginia suffered an explosion. Both of these incidents, and others, changed the regulatory rules governing the transmission of these hazardous substances. By October 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a ruling on new regulations that amended the Federal Pipeline Safety Regulations. The final regulatory ruling published in November 2021 with a six-month window for compliance.

What is the history of the PHMSA mega rule? How does it affect PHMSA MAOP verification? This blog has answers that will help you understand the reasoning and history behind the PHMSA mega rule—as well as its implications.

What Led to the PHMSA Mega Rule?

Pipeline failures don’t happen frequently, but several devastating accidents led to the biggest change in public policy in the oil and gas sector that we’ve seen in decades. When a 30-inch steel pipeline exploded with gas in a residential California neighborhood in 2010, eight people were killed and 58 injured. The explosion and subsequent fires burned for days, with a total cost of around $1.6 billion. Later, a judge handed down an additional $3 million fine for PG&E, the California utility giant, the maximum penalty allowed by law. That same year, an oil pipeline ruptured in a Lake Michigan tributary; cleanup took five years. These were just a few of the highly publicized incidents that led to the PHMSA mega rule.

For obvious reasons, the oil and gas industry is highly motivated to pursue behaviors that protect public health as participants conduct their business. The industry has long been governed by federal and even state regulations that ensure the safety of the transmission of toxic and volatile chemicals that are key to the very society that we live in. In 2019, federal safety requirements underwent a massive shift in policy that was really the cumulation of a decade of evaluation of the existing rules. Today, the industry is governed by a new set of safety standards called the PHMSA mega rule. The regulations affected more than 400,000 miles of onshore pipelines in the energy sector. All vendors must follow these new rules by May 15, 2022 or face further industry and regulatory scrutiny.

What Are the Implications of the PHMSA Mega Rule?

Implications of the PHMSA Mega Rule

By 2020, the implications of the PHMSA mega rule were being felt. The new rule created two new categories of regulated lines, and sought to address “certain previously unregulated rural gas gathering lines,” according to JDSupra. The new rules require annual reporting for anyone that falls under these categories. Lightbox says it “essentially doubles previous regulations for onshore gas transmission.” The PHMSA mega rule is in three sections and requires:

  • Any gas transmission companies with pipelines constructed before 1970 to test the material strength of their lines by submitting PHMSA maximum allowable operating pressure (MAOP) verification to the agency.
  • Companies to comply with new repair requirements within a specific timeframe following extreme weather events or natural disasters. Leak detection systems must be installed or increased and the integrity of pipelines must be assessed every 10 years, at minimum.
  • PHMSA to now have the authority to issue emergency orders to address imminent hazards or unsafe conditions in a pipeline such as faulty components.

How will the PHMSA mega rule affect the pipeline industry going forward?

The PHMSA Mega Rule’s Effect on the Energy Sector

From PHMSA MAOP verification to annual reporting, the mega rule will definitely have an impact going forward. According to the regulation, pipeline companies have 14-years to fully comply, beginning in July, 2020. However, mandated compliance with the tenets of the regulations occurs gradually during this timeframe. For example:

  • By July 1, 2021, pipeline operators needed to document procedures and have an integrity management plan in place to address how they would eliminate leaks or other pipeline disruptions.
  • By May 15, 2022, certain types of line operators must begin submitting their annual PHMSA MAOP verification reports.

Also, companies that had pipelines installed before 1970 were previously unregulated. The PHMSA mega rule changed that loophole. It also adds regulations to gas gathering lines, which are the small pipes that pull gas away from the production point to another facility for refinement or distribution. These, and other examples, show that the energy sector is scrambling to imply with the PHMSA mega rule.
