Pipeline and Hazardous Materials Safety Administration

[Docket No. PHMSA-2015-0139]

Pipeline Safety: PHMSA Pipeline Risk Modeling Methodologies 
Public Workshop

AGENCY: Pipeline and Hazardous Materials Safety Administration, DOT.

ACTION: Notice of public meeting.


SUMMARY: This notice is to announce a public workshop to discuss the 
advancement of risk modeling methodologies of gas transmission and 
hazardous liquid pipelines, and the risk modeling methodologies used 
for non-pipeline systems. This workshop will bring industry, Federal 
and state regulators, interested members of the public, and other 
stakeholders together to share knowledge and experience on risk 
modeling within the pipeline industry and other fields, ways to advance 
pipeline risk models, and practical ways that operators can adopt and/
or adapt them to the analyses of their systems.

DATES: The public workshop will be held on Wednesday, September 9, 
2015, from 8:00 a.m. to 5:00 p.m., EST, and Thursday, September 10, 
2015, from 8:00 a.m. to 12:00 p.m. EST. (Changes to start or finish 
times will be updated on the PHMSA meeting page Web site, along with 
the meeting agenda https://primis.phmsa.dot.gov/meetings/MtgHome.mtg?mtg=104.)

ADDRESSES: The workshop will be held at the Crystal City Marriott at 
Reagan National Airport, 1999 Jefferson Davis Highway, Arlington, VA 
22202. Please see the meeting Web site for hotel room block information 
at https://primis.phmsa.dot.gov/meetings/MtgHome.mtg?mtg=104.

    The Federal pipeline safety regulations (49 CFR part 192 Subpart O; 
49 CFR Sec.  195.452) requires operators to continually examine ways to 
reduce the threats to pipelines in order to minimize the likelihood of 
a release, and ways to reduce the consequences of potential releases. A 
primary tool to implement this process is generally referred to as a 
``risk analysis'' or ``risk assessment.''
    To support integrity management requirements, a risk analysis 
modeling approach must be able to adequately characterize all pipeline 
integrity threats and consequences concurrently, and the impact of 
measures to reduce risk must be evaluated.
    This workshop will focus on advancing risk modeling approaches by 
looking at risk modelling methodologies for pipeline and non-pipeline 
systems, and practical ways that operators can adopt and/or adapt them 
to the analyses of their systems.


    Subsequent to implementation of the integrity management rules, 
industry has adopted a variety of approaches to risk analysis. Many of 
these approaches are variations of the ``risk index'' models. Index 
models and other basic approaches to risk modeling have been 
implemented by industry for purposes such as risk-ranking pipeline 
segments to prioritize initial integrity management-required baseline 
assessments. Additional opportunities to utilize these approaches to do 
more investigative oriented analyses in order to identify specific ways 
to reduce risks are being explored.
    As summarized and discussed in past public forums and workshops on 
pipeline safety (e.g., 2014 Government/Industry Pipeline R&D Forum), 
industry and PHMSA are in general agreement that risk models need to 
evolve in such a way as to be more investigative in nature.
    PHMSA believes that improving risk models is important for further 
reducing the risk of pipelines to the public health and safety. In 
particular, PHMSA is interested in specific ways to advance pipeline 
risk models, and in practical ways that operators can adopt and/or 
adapt risk models to the analyses of their systems.

    Issued in Washington, DC, on August 10, 2015, under authority 
delegated in 49 CFR 1.97.
