SB2661 authorizes owners or operators of pipeline facilities to use risk-based inspections to satisfy inspection requirements for in-service breakout tanks under the existing pipeline-safety regime. The bill also directs the Secretary of Transportation, acting through the Pipeline and Hazardous Materials Safety Administration, to revise 49 CFR 195.432 to permit risk-based inspections for these tanks, as soon as practicable after enactment.
At a Glance
What It Does
Allow owners or operators to use risk-based inspections to comply with inspection requirements for in-service breakout tanks under Chapter 601. Require PHMSA to revise 49 CFR 195.432 to enable this approach.
Who It Affects
Owners or operators of pipeline facilities with in-service breakout tanks; PHMSA and DOT regulators; inspectors and third-party inspection entities.
Why It Matters
Introduces a risk-based method into a niche but safety-critical area, enabling regulatory alignment with modern risk-management practices and potentially more efficient inspections.

What This Bill Actually Does
The bill makes a targeted change to the way in-service breakout tanks—tank assets embedded in pipeline facilities—are inspected. It allows owners and operators to use risk-based inspections as a method to satisfy the current inspection requirements found in Chapter 601 of Title 49, United States Code.
The scope ties these breakout tanks to the broader pipeline safety framework, including relevant provisions established under Chapter 195 or its successor regulations. The practical effect is to give regulated entities the option to base inspection activity on identified risks and data-driven judgments rather than a one-size-fits-all checklist, as long as those inspections remain compliant with existing statutory requirements.
In addition, the bill directs the Secretary of Transportation, through the Administrator of the Pipeline and Hazardous Materials Safety Administration (PHMSA), to revise section 195.432 of Title 49, CFR, to permit risk-based inspections for in-service breakout tanks. This rulemaking obligation is to occur as soon as practicable after enactment.
The combination of authorization and required rulemaking creates a path for modernizing oversight in this area without altering the fundamental safety standard—it simply changes how compliance can be demonstrated within the current legal framework. Overall, SB2661 envisions a tighter integration of risk-based inspection methods with the established inspection regime, leveraging existing statutory authorities and regulatory constructs to accommodate a more flexible, data-informed approach for a specific class of equipment.
Regulators, operators, and inspection professionals would need to align their practices with updated CFR language once the rulemaking is complete, ensuring consistency across inspections and safety outcomes.
The Five Things You Need to Know
The bill authorizes risk-based inspections for in-service breakout tanks under Chapter 601 inspection requirements.
Owners or operators of pipeline facilities with breakout tanks may use risk-based inspections to comply.
PHMSA must revise 49 CFR 195.432 to permit risk-based inspections of in-service breakout tanks.
The authority explicitly references Chapter 195 (or successor regulations) in connection with risk-based inspections.
No new inspection standards are created; the bill enables a risk-based method within the existing regulatory framework.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Authorization for risk-based inspections for in-service breakout tanks
Beginning on enactment, owners or operators of pipeline facilities may use risk-based inspections to comply with the inspection requirements under Chapter 601 for in-service breakout tanks. This explicitly links breakout tanks to the existing regulatory framework and allows a risk-based approach to satisfy those requirements, provided it remains within the scope of the current statutory regime.
Rulemaking to implement risk-based inspections
As soon as practicable after enactment, the Secretary of Transportation, acting through the Administrator of PHMSA, must revise section 195.432 of Title 49, CFR to allow risk-based inspections of in-service breakout tanks in accordance with subsection (a). This creates a concrete obligation to update the regulatory text to reflect the new inspection method.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Owners and operators of pipeline facilities with in-service breakout tanks gain flexibility to apply risk-based inspection methods within the current regulatory framework.
- Third-party inspectors and engineering firms can offer risk-based assessment services tailored to breakout tanks.
- PHMSA and DOT regulators can align oversight with modern risk-management practices and streamlined inspection outcomes.
- Insurance providers may benefit from clearer, risk-informed inspection data that informs risk profiles.
- Industry associations representing pipeline operators gain clearer guidance on compliant, risk-based approaches.
Who Bears the Cost
- Owners and operators may incur upfront costs to develop or procure risk-based inspection capabilities, data systems, and training.
- Small or resource-constrained facilities may face transition and capability challenges to implement risk-based methods.
- Regulators and PHMSA face costs associated with updating CFR 195.432 and issuing guidance for the new approach.
- Inspection contractors and consultancies may need to adjust methodologies and staffing to support risk-based inspections.
Key Issues
The Core Tension
Balancing regulatory flexibility with safety assurance: risk-based inspections can improve efficiency and focus where risk is highest, but depend on reliable data, transparent methodologies, and rigorous oversight to avoid under-inspection.
The bill introduces a notable shift by allowing risk-based inspections for a specific class of assets, but it relies on data quality and robust risk models to preserve safety outcomes. Implementing the change depends on timely rulemaking to revise CFR 195.432, which introduces uncertainty about when new procedures will take effect.
The approach must remain anchored in the existing statutory framework (Chapter 601 and Chapter 195 or successor) to avoid creating gaps between inspection requirements and enforcement expectations. Practical challenges include developing consistent risk-based methodologies that can be validated across facilities and ensuring that regulators retain effective oversight during the transition.
