Western Region Facts • Western Region encompasses 12 states • 26 Inspectors and 3 Contractors • Regional office Based in Lakewood, CO • Major Satellite offices in Anchorage, AK and Ontario, CA • One man field offices in Billings, MT, Cheyenne, WY, and Reno, NV
CATS Western Region Focus • Public Complaints/Whistleblowers • Technical Support Re: Pipeline Safety Regulations • Emergency Response – Information dissemination including incident causes and PHMSA safety actions • Permits – Foster relationships with other Federal/State/Local agencies and pipeline operators • Pipeline Safety Education - public and gov’t officials • Operators’ Public Awareness Program Effectiveness Evaluations (PAPEE)
Western Region (WR) CATS Example 1 • Products pipeline – Willard Bay, UT (March 2013) • Low frequency seam failure • Focus on communication (federal, state, local public officials) to cause and mandated remedial actions • Ongoing communication through startup and ongoing repairs and tests.
WR CATS Example 2 • Products pipeline – Lodge Grass, MT (July 2013) • Failure due to land movement • Facilitated Interaction between Crow Nation leaders and pipeline operator due to cause and follow PHMSA actions • Communication with public officials due to remoteness
WR Safety Challenges • Low stress and rural gathering lines applicability – Finding those operators who do not think they are regulated by PHMSA • AC Interference/Lightning • Landslide Areas • Seasonal flash flooding events • Encroachment of urban areas and parallel utility/pipeline construction • Aging Infrastructure Being Overly Amortized - Bandaids • Impact of Shale Oil/Gas: New, Reversed, Converted Pipelines • Challenges to Recruit, Train and Retain Qualified Workforce • The World is Watching – Bloggers and the Internet
Integrity Management (IM) • IM Program Working: • ILI tools advancement in technology (MFL, geometry, crack, seam, stress/strain) continue to identify integrity threats before they can fail • Systems being reassessed and compared to previous ILI results thereby finding changes in pipe condition • Fewer incidents caused by: • Corrosion • Outside Force Damage (dents/gouges)
Who Regulates Pipelines • Individual state • U.S. DOT , PHMSA In California: • Hazardous Liquid Pipelines • CSFM Regulates Intrastate pipelines • PHMSA Regulates Interstate pipelines • Natural Gas Pipelines: • CA PUC Regulates Public Utilities systems within CA • PHMSA Regulates all other systems (municipal distribution, master meter, non-public utility transmission)
Jurisdictional Vs. Regulated? • Jurisdictional: Transportation of hazardous liquid by pipeline under Part 195 • Regulated: Pipeline facilities and the transportation of gas that are not exempted under Part 195.1(b) • In plant • Gravity • Other modes of transportation
Regulatory UpdateThis PHMSA website link http://www.phmsa.dot.gov/pipeline/regs/rulemakinghas the status of federal rulemaking Not much new in 2013-2014
Rulemakings in Process • Safety of On-Shore Hazardous Liquid Pipelines (NPRM stage) • Excavation Damage Prevention (Final Rule stage) • Miscellaneous Rulemaking (Final Rule stage) • EFV Expansion beyond Single Family Residences (NPRM stage) • Safety of Gas Transmission and Gathering Lines (NPRM stage) • Operator Qualification, Cost Recovery and Other Pipeline Safety Proposed Changes (NPRM stage) • Plastic Pipe (NPRM stage) • Standards Update (Final Rule stage) • Rupture Detection and Valve Rule (NPRM stage)
Current Rulemakings in Process Safety of On-Shore Hazardous Liquid Pipelines (NPRM stage) • NPRM moved past PHMSA • ANPRM published 10/18/2010 • Major topics under consideration: • Assessments beyond High Consequence Areas (HCAs) • Leak detection beyond HCAs • Repair criteria in HCA and non-HCA areas • Stress Corrosion Cracking (SCC) • Piggability of lines • Reporting requirements for Gathering lines • Gravity Line exception
The Pipeline Inspector • Regular People, believe it or not? (like Operations people) • Hired to protect the public and environment from pipeline inherent risks (Enforce Pipeline Safety Regulations) • 80+ days away from home • Plenty of windshield time • Typically no Hilton where Interstate Pipelines are • Not out to “get-em” philosophy • We do not get graded on finding something wrong • Another information resource for operators
Inspector’s Role • #1 tool to enforce regulations is phone call and showing up • Ask plenty of questions – and listen • Be considerate and cooperate with the operator • Meeting time/place • Understand operators file keeping process • Different set of outside eyes on safety • Should learn something new each inspection • Inform operator of deficiencies/concerns upon leaving • Why I do it: • Great people and industry • Would rather be on the ROW than in office
It’s Inspection Time • Don’t panic • Should be prepared every day • Records in order • Business as usual • Typically scheduled • Your time to show off your pipeline safety program • Ask questions and be cooperative • Don’t be afraid to voice your opinion • Seems tougher on the inspector than operator
New PHMSA Inspection Tool • IA – Inspection Assistant • A tool for Inspector’s to capture results from questions • A software application installed on a laptop (client/server solution) • Replaces standard MSWord inspection forms and questions • Electronically records inspection results in database for historical trending • Provides considerations/guidance to Inspector to determine compliance to regulations • Considerations are for inspector guidance only. They are memory joggers. They are not meant to replace the code

Pipeline and Hazardous Materials Safety Administration Hazardous Liquid IM Program Huy Nguyen 12300 West Dakota Avenue, Suite 110 Lakewood, CO 80228 huy.v.nguyen@dot.gov
General Topics • Overview • Observations • Western Region Focus Areas
Objectives for the HL IM Program • Accelerate and improve the quality of integrity assessments conducted on pipelines in areas with the highest potential for adverse consequences, • Promote a more rigorous, integrated, and systemic management of pipeline integrity and risk by operators, • Strengthen government’s role in the oversight of pipeline operator integrity plans and programs, and • Increase the public’s confidence in the safe operation of the nation’s pipeline network.
Overview of HL IM Program • Hazardous Liquid Pipelines - ~186,000(1) miles. • Over 79,000(1) miles or 43% of all hazardous liquid pipelines designated as potentially affecting a high consequence area. • 8100(1) immediate repair conditions have been remediated • 32,000(1) 60 and 180-day conditions have been remediated (1) – 2012
Program Elements for the HL IM Program • Segment Identification • Risk Analysis • Baseline Assessment Plan • Assessment Results Review • Remediation • Preventive and Mitigative Measures • Continual Assessment • Performance Evaluation

Observations • Operators generally understand the Rule and are implementing the assessment provisions of the Rule. • Operator interactions have been generally cooperative with open communication. • Operators of small systems may be more likely to contract out significant portions of IM program development. • Operators now have an improved understanding of the condition of pipelines in the safety-sensitive areas.
Observations • Operators are generally making progress toward developing the mature, proactive IM Program. • Progress is needed in development and implementation of several IMP elements • Preventive & Mitigative Measures • Continual Evaluation • Performance Evaluation • Remediation
