What to do
Conduct special one-time surveys for non-typical soil conditions.
Implement leak management program using ANSI/GPTC Z380.1 standards.
Re-evaluate distribution integrity management programs every 5 years minimum.
Maintain all compliance records for at least 10 years.
Compliance Answer: Enhanced Data Reporting and Emergency Response Planning for U.S. Natural Gas Pipelines
The U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) has expanded information collection and recordkeeping requirements for natural gas pipeline operators under 49 CFR Part 192, focusing on class location changes, leak management programs, and emergency response planning. Below is a structured breakdown of the key compliance obligations, deadlines, and authorities.
1. Class Location Change Records (Integrity Management Alternative)
Requirement: Operators of gas transmission pipelines experiencing a class location change who elect to use the Integrity Management (IM) alternative must:
- Amend their Operation and Maintenance (O&M) manuals to incorporate IM program requirements1.
- Maintain traceable, verifiable, and complete (TVC) records of all actions taken to comply with IM requirements for the life of the pipeline1.
- Update O&M manuals for approximately 137 affected pipeline miles, with an estimated 80 burden hours per mile1.
Burden Estimate:
- Total Annual Responses: 1371.
- Total Annual Burden Hours: 10,9601.
- Frequency: On occasion (triggered by class location changes)1.
Authority:
- 49 CFR 1.48 (PHMSA rulemaking authority)1.
- Paperwork Reduction Act (PRA) of 1995 (44 U.S.C. Chapter 35)1.
Public Comment Period:
- PHMSA solicited comments on the practical utility, burden estimates, and minimization strategies for this collection until August 12, 2026.
2. Leak Management and Emergency Response Planning
Requirement: Operators must:
- Implement an effective leak management program under § 192.1007(d), including:
- Leak investigation and classification (Section 5 of PHMSA guidelines).
- Emergency response guidance for non-typical soil conditions (e.g., soil that may strip odorant from natural gas).
- Special one-time leak surveys when gas migration or weather conditions hinder detection (per GM 192.723).
- Re-evaluate Distribution Integrity Management Programs (DIMP) at least every 5 years, incorporating:
- New knowledge from incidents, leak history, or environmental changes.
- ANSI/GPTC Z380.1 standards for non-typical soil conditions.
- Maintain records for 10 years demonstrating compliance with 49 CFR Part 192, Subpart P, including:
- Threat identification and risk analysis documents.
- Measures to reduce pipeline failure risks.
Authority:
- 49 CFR Part 192, Subpart P (DIMP requirements).
- PHMSA Advisory Bulletin (non-binding guidance).
3. Recordkeeping and Data Collection
Key Obligations:
| Regulation | Key Requirement | Deadline/Threshold | Authority |
|---|---|---|---|
| Class Location Change | Update O&M manuals for IM alternative; maintain TVC records for life of pipeline1. | On occasion (triggered by changes) | 49 CFR 1.48; PRA1 |
| Leak Management | Implement leak surveys, emergency response plans, and DIMP re-evaluations. | Every 5 years (minimum) | 49 CFR 192.1007(d) |
| Record Retention | Retain compliance records (e.g., threat analysis) for 10 years. | 10-year retention period | 49 CFR 192.1011 |
| Non-Typical Soil Response | Incorporate ANSI/GPTC Z380.1 for leak investigations in non-typical soils. | As needed (emergency response) | PHMSA Advisory Bulletin |
4. Public Comments and PHMSA Adjustments
- Pipeline Safety Trust (PST) argued that TVC recordkeeping for pressure tests and pipe materials is a pre-existing obligation under pipeline safety regulations (PSR) and should not be double-counted in the Class Location Change burden estimates.
- PHMSA acknowledged the comment and removed duplicative burden estimates for TVC records.
Summary Answer
PHMSA has expanded compliance requirements for U.S. natural gas pipeline operators under 49 CFR Part 192, including:
- Class Location Changes: Operators must update O&M manuals and maintain TVC records for IM alternatives, with an estimated 10,960 annual burden hours1.
- Leak Management: Mandatory 5-year DIMP re-evaluations, emergency response plans for non-typical soils, and 10-year record retention.
- Public Comment: PHMSA adjusted burden estimates after feedback on duplicative TVC requirements.
Key Authorities: 49 CFR 1.48, 49 CFR Part 192 (Subpart P), and the Paperwork Reduction Act1. Operators must comply with these requirements on occasion (class location changes) or periodically (DIMP re-evaluations)1.
