Underlying Principles
• The pipeline operator is ultimately responsible for their infrastructure:
– It is the responsibility of pipeline operators to understand and manage the risks associated with their pipelines.
• The regulator can influence operator performance by setting standards
• PHMSA also strives to impact operator performance beyond mere compliance with the regulations

What are we talking about?
• Shifting supply sources for oil and natural gas results in construction of new pipelines, reversing the flow on existing pipelines and changing product type in pipelines.
• The supply shift has been caused by the increased importation of Canadian crude and domestic production (shale plays).
• PHMSA has been monitoring this condition relative to pipeline safety and potential new policies needed.

Routing and Siting • Routing responsibility is:
– Federal Energy Regulatory Commission (FERC): Interstate gas pipelines, Liquefied Natural Gas Plants
– State/Local Government: Hazardous Liquid (crude oil, refined products)
• PHMSA’s role is pipeline safety
– Participation in public meetings (by our “CATS” people)
– Inspection and enforcement of pipeline safety regulations

Pipeline Reversals • Not specifically addressed in 49 CFR Parts 192 & 195, however
operators must consider threat impact on all operations e.g.:
– Operations and Maintenance (O&M) Plans/Manual • Integrity Management Program
• Over-pressure protection and surge pressures
• Control Room Management
• Operator Qualification
– Spill Response Plans
• “Grandfathered” gas pipelines, need to review method used to establish maximum allowable operating pressure (MAOP):
– MAOP based on pressure gradient or over 72% SMYS
• Special permit pipelines will be addressed for renewal

Service Conversions
• Addressed in Gas (192.14) and Hazardous Liquid (195.5) Regs
• Requires review of pipeline life cycle operating history
– Design, construction, operation, and maintenance
• Pipeline inspected for defects with remediation
• Pressure test, based on code requirements
• Integrity Management:
– Update HCAs, conduct assessments, remediate threats, conduct pressure and fatigue analysis, and implement monitoring
• Records kept for life of pipeline

Product Changes
• Not specifically addressed in 49 CFR Parts 192 & 195, however operators must consider threat impact on all operations e.g.:
– Operations and Maintenance (O&M) Plans/Manual • Integrity Management Program
• Over-pressure protection and surge pressures
• Control Room Management
• Operator Qualification
– Spill Response Plans
• Conversion from natural gas to crude (or other) requires service conversion review

Construction
• PHMSA has increased focus on pipeline construction since 2007
• Operators now must provide 60 days advance notification of construction projects
• Liquefied Natural Gas (LNG); projects have increased significantly

Forward Look
• Guidelines for flow reversals, service conversions and product changes
• Integrity Management “2.0”
• Operator Qualification for construction
• Quality Management Systems for construction
• Integrity Verification Process: Record keeping and methods used to establish maximum (allowable) operating pressure
