PHMSA has released updates to several key forms. The most recent changes went into effect on July 7, 2025, and include the following:

• OpID Assignment Request  F1000.1
• OpID Assignment Request Instructions  F1000.1
• National (formerly Operator) Registry Notification Form F 1000.2
• National (formerly Operator) Registry Notification Instructions F 1000.2

Earlier updates were also made on April 29, 2025, affecting both registration and reporting forms:

• OpID Assignment Request Form F 1000.1
• OpID Assignment Request Instructions F 1000.1
• National (formerly Operator) Registry Notification Form F 1000.2
• Hazardous Liquid/CO2 Accident Report F7000-1
• GRR-Hazardous Liquid Accident Report Form F 7000-2
• Gas Transmission and Gathering Annual Report Instructions F 7100
• Gas Transmission, Gathering, and UNGS Incident Report Form F 7100.2

Operators should ensure they are using the latest versions when submitting documentation to PHMSA.

On June 13, 2025, PHMSA rescinded ADB-2021-01—and any PHMSA policy statements, letters of interpretation, guidance documents, congressional testimony, and public statements that rely on or assert the reading of the section 114 mandate expressed in ADB-2021-01.  Owners and operators of pipeline facilities should adhere to the text of section 114 of the 2020 PIPES Act and section 60108(a) of the Pipeline Safety Act in developing and implementing their inspection and maintenance plans. PHMSA and State authorities should do the same in considering the factors in section 60108(a)(2) and in exercising their inherent enforcement discretion to decide whether an operator’s inspection and maintenance plan is adequate.

Editor’s Note:
Operators should remember that they are required to comply with their O&M manual as written – even if the manual exceeds the requirements of the rule or law.  To get the full benefit of the ADB rescission, operators will need to revise their written procedures to eliminate statements which are no longer required.  RCP’s staff stand ready to assist in that effort.  Contact Jessica Foley at jfoley@rcp.com.

[Docket No. PHMSA-2025-0019]

PHMSA published an advance notice of proposed rulemaking (ANPRM) on May 21, 2025, to gather stakeholder feedback on potential amendments to Parts 192 and 195 including repair timelines, remediation criteria, integrity management rules, and re-assessment intervals to ensure regulations maintain pace with modern technology and best practices without imposing unnecessary burdens. Additionally, PHMSA is requesting feedback pertaining to the authorization of a risk‑based approach for determining inspection intervals on in‑service breakout tanks.

The ANPRM noted that hazardous liquids and carbon dioxide repair requirements have not been substantially updated for decades, and they may not sufficiently provide for the use of advanced technology and current pipeline industry best practices. PHMSA has requested comments pertaining to:

• Anomaly categorization and remediation timelines for could affect (HCA) and non-could affect pipelines
• Alternatives to existing anomaly repair criteria and remediation timelines
• Anomaly evaluation methods in the absence of known material properties
• Adopting predicted failure pressure-based criteria for anomalies
• Repair criteria timelines for metal loss anomalies along a longitudinal seam weld for could affect (HCA) and non-could affect pipelines
• Dent evaluations and Engineering Critical Assessments
• Dents with metal loss or other interacting threats

With respect to gas transmission pipelines, PHMSA stated that gas transmission repair criteria were last revised in 2022 following the San Bruno incident; some of those changes are under litigation and PHMSA has not conducted a holistic review since. PHMSA requested comments pertaining to:

• Dents and Engineering Critical Assessments
• Engineering Critical Assessment methodologies using current industry standards
• Cost and benefits associated with Engineering Critical Assessments
• Dents with metal loss or other interacting threats
• Re-assessment for anomalies that were evaluated using Engineering Critical Assessments

For hazardous liquid breakout tanks, PHMSA has requested feedback pertaining to how tanks should be inspected and repaired, and inspection frequencies.  PHMSA asks if incorporating a risk-based inspection interval would be appropriate for breakout tanks.

Public comments are due by July 21, 2025, and PHMSA plans to hold a public meeting to supplement or to clarify the materials received.

This August, RCP and the Pipeline Safety Institute are offering a special edition of the DOT Pipeline Compliance Workshop focused entirely on natural gas pipelines.

Unlike our standard DOT workshop, which covers both gas and liquid pipelines, this session is designed specifically for those working exclusively with gas pipeline systems. Whether you’re new to compliance or looking to stay current with evolving PHMSA regulations, this workshop offers a focused opportunity to build confidence and sharpen your knowledge without the distraction of liquid pipeline content.

Tailored for gas pipeline operators, engineers, compliance professionals, and regulators, this interactive three-day workshop provides practical, in-depth training on 49 CFR Parts 191 and 192, covering topics such as:

• DOT/PHMSA compliance framework
• Roles of federal and state pipeline safety agencies
• Navigating the code: key terms and definitions
• Maximum Allowable Operating Pressure (MAOP)
• Overpressure protection and regulators
• Operations and maintenance, test requirements
• Corrosion control requirements
• Transmission and distribution integrity management (TIMP and DIMP)
• Operator Qualification (OQ)

Location: Houston, TX

Dates: August 5-7, 2025

The Enforcement Corner summarizes recent PHMSA enforcement actions, indicating where PHMSA is putting its enforcement efforts and the fines they are proposing for various types of violations.

PHMSA has not posted any new enforcement actions after May 2025. We will continue to monitor the system to provide you the most up to date information.

Please note:

1. Pipeline operators may disagree in whole or in part with each proposed violation cited by PHMSA. 
2. Proposed Civil Penalties (PCP) may be reduced or eliminated before an enforcement action becomes final.
3. A Corrective Action Order (CAO) usually addresses urgent situations arising out of an accident, spill, or other significant, immediate, or imminent safety or environmental concerns.
4. A Notice of Amendment (NOA) is frequently a result of a difference of opinion regarding written procedure requirements.
5. A Notice of Proposed Safety Order (PSO) addresses pipeline integrity risks that may not constitute a hazardous facility requiring immediate corrective action (see Corrective Action Order described above), but do need to be addressed over time.
6. A Notice of Probable Violation (NOPV) is not proof that a violation actually occurred.
7. Proposed Compliance Orders (PCO) frequently document actions the pipeline operator already planned to do.
8. Warning Letter (WL) is an official notice by PHMSA that an operator needs to make improvements but that no further enforcement is proposed for those findings at this time.

RCP maintains a detailed database of all PHMSA enforcement actions dating back to 2007 and is routinely asked for data analysis of various enforcement actions. For more information on how RCP can assist with enforcement action data analysis services, contact Jessica Foley.

Need to respond to a PHMSA enforcement action?
Need to know if your enforcement action is an outlier, or par for the course? 
RCP maintains a detailed database of all PHMSA enforcement actions and their resolution which enables us to compare and contrast individual enforcement actions to nationwide actions and trends.  We can help put things into context to ensure an effective reply for each citation.  For more information on how RCP can assist with enforcement action data analysis services, contact Jessica Foley.

Do you have questions? RCP’s SMEs have the answers. Information will be posted here for questions we often get from clients or discussions we have with regulators regarding interpretations and pending regulatory deadlines.

Q:  Does any portion of a 192.635 “Notification of Potential Rupture” require OQ training as a covered task?

A: Yes, 192.635 “Notification of Potential Rupture” implicitly requires that employes and contractors who work along the ROW (or who remotely monitor pipelines) are able to identify potential ruptures and know how to respond. This competency should be incorporated into the operator’s Operator Qualification (OQ) program, as well as into Control Room Management (CRM) training.
