The Who, What, Where, When, Why and How of the PHMSA Mega Rule

Who:

The PHMSA Mega Rule is a set of regulations introduced by the Pipeline and Hazardous Materials Safety Administration (PHMSA), a federal agency under the U.S. Department of Transportation. It applies to operators of pipelines involved in the transportation of hazardous materials, including natural gas and petroleum products.

What:

The PHMSA Mega Rule is a comprehensive set of regulations aimed at enhancing pipeline safety and reducing failures. It consists of three parts, each addressing different aspects of pipeline operations and integrity.

Where:

The regulations apply to pipeline operators throughout the United States.

When:

The PHMSA Mega Rule has been implemented in stages, with each part having its own effective date:

- Part One: It went into effect on July 1, 2020.

- Part Two: It went into effect on May 24, 2023.

- Part Three: It was published on August 24, 2022, and took effect on May 16, 2023.

Why:

The PHMSA Mega Rule was introduced in response to concerns about pipeline safety following incidents such as the 2010 natural gas pipeline rupture in San Bruno, CA. Its primary goal is to enhance the safety and reliability of the nation's pipeline infrastructure, protect the environment, and ensure public health. By implementing stricter regulations, the PHMSA aims to reduce the frequency of pipeline failures and incidents.

How:

The PHMSA Mega Rule achieves its objectives through the following measures:

Part One:

- Requires operators to reconrm the maximum allowable operating pressure (MAOP) of their transmission pipelines.

- Introduces reporting obligations for pipeline operators.

- Enhances safety measures related to in-line inspection (ILI) launcher and receiver facilities.

- Extends requirements to additional pipelines located in Moderate Consequence areas.

Part Two:

- Claries integrity management regulations for onshore gas transmission pipelines.

- Expands corrosion control requirements, including analysis after line backll events using external corrosion direct

assessment (ECDA).

- Mandates inspections after extreme weather events.

- Updates repair criteria for high-consequence and non-high consequence areas (HCA) pipelines.

- Adds additional requirements for leak detection on gas pipelines.

Part Three:

- Extends corrosion control requirements to gas gathering lines, adding 400,000 miles of pipelines to reporting obligations.

- Introduces the Type C designation for gathering lines, requiring similar corrosion control, leak survey, and repair standards

as transmission pipelines.

- Enhances oversight and reporting obligations for operators.

Operators must comply with the specic requirements outlined in each part of the rule to achieve compliance. Compliance may involve activities such as verifying MAOP, identifying Moderate Consequence areas, implementing integrity management best practices, corrosion control measures, and improving incident tracking and reporting.

To assist operators in meeting these compliance obligations, companies like American Innovations offer comprehensive solutions such as pipeline mapping, data collection, hardware, software, corrosion management expertise, close-interval surveys, and cathodic protection services. These solutions ensure accurate digitization of pipeline infrastructure and records and provide support and guidance throughout the compliance process.
