        PHMSA is publishing this notice to seek public comments on a report developed to support improvements in gas and hazardous liquid pipeline risk models titled "Pipeline Risk Modeling--Overview of Methods and Tools for Improved Implementation" (Pipeline Risk Modeling Report). Pipeline risk models are a foundational part of the assessment of operational pipeline risk. Federal pipeline safety integrity management (IM) regulations require pipeline operators to use risk assessments. Based on the results of pipeline inspections and failure investigation findings, both PHMSA and the National Transportation Safety Board (NTSB) have identified general weaknesses in the risk models often used by pipeline operators in performing risk assessments for their IM programs. The Pipeline Risk Modeling Report considers the major types of pipeline risk models, and the effectiveness of each type in supporting risk assessments, as applied to pipeline operator decisions.

SUMMARY: PHMSA is publishing this
notice to seek public comments on a
report developed to support
improvements in gas and hazardous
liquid pipeline risk models titled
‘‘Pipeline Risk Modeling—Overview of
Methods and Tools for Improved
Implementation’’ (Pipeline Risk
Modeling Report). Pipeline risk models
are a foundational part of the
assessment of operational pipeline risk.
Federal pipeline safety integrity
management (IM) regulations require
pipeline operators to use risk
assessments. Based on the results of
pipeline inspections and failure
investigation findings, both PHMSA and
the National Transportation Safety
Board (NTSB) have identified general
weaknesses in the risk models often
used by pipeline operators in
performing risk assessments for their IM
programs. The Pipeline Risk Modeling
Report considers the major types of
pipeline risk models, and the
effectiveness of each type in supporting
risk assessments, as applied to pipeline
operator decisions.

SUPPLEMENTARY INFORMATION: PHMSA is
issuing the Pipeline Risk Modeling
Report to support improvements in
pipeline risk models and requests
public comments. Both PHMSA and
NTSB have identified a need to address
the risk models often used by pipeline
operators in performing risk
assessments for their IM programs and
provide guidance where appropriate.
NTSB has issued three
recommendations to PHMSA in this
area. NTSB Recommendation P–15–10
recommends that PHMSA update
guidance for gas transmission pipeline
operators and inspectors on the
evaluation of interactive threats,
including the listing of all threat
interactions that must be evaluated and
acceptable methods to be used.1 NTSB
Safety Recommendation P–15–12
recommends that PHMSA evaluate the
safety benefits of the four risk
assessment approaches currently
allowed by the gas integrity
management regulations; determine
whether they produce a comparable
safety benefit; and disseminate the
results of your evaluation to the
pipeline industry, inspectors, and the
public.2 Lastly, NTSB Recommendation
P–15–13 recommends that PHMSA
update guidance for gas transmission
pipeline operators and inspectors on
critical components of risk assessment
approaches, including (1) methods for
setting weighting factors, (2) factors that
should be included in consequence of
failure calculations, and (3) appropriate
risk metrics and methods for aggregating
risk along a pipeline.3 PHMSA is
addressing these recommendations
through the Risk Modeling Report
process.
PHMSA organized a Risk Modeling
Work Group (RMWG) composed of
representatives of state and federal
pipeline regulators, pipeline operators,
industry organizations, national
laboratory personnel, and other
stakeholders. The purpose of the RMWG
was to gather information regarding
state-of-the-art pipeline risk modeling
methods and tools, the use of those
methods and tools, and the resulting
data in operator IM programs. The
Pipeline Risk Modeling Report provides
an overview of methods and tools for
improved implementation based on the
results of the RMWG. The RMWG
meeting notes and presentations can be
reviewed at: https://
primis.phmsa.dot.gov/rmwg/index.htm.
The Pipeline Risk Modeling Report
considers the major types of pipeline
risk models, and the effectiveness of
each type in supporting risk
assessments, as applied to pipeline
operator decisions. The four major risk
model categories considered for gas and
hazardous liquid pipelines are:
• Qualitative;
• Relative Assessment/Index;
• Quantitative System, and
• Probabilistic.
Each model category is characterized
by the model inputs, outputs, and
algorithms and was evaluated according
to its ability to support pipeline risk
management decisions and regulatory
requirements.

Advisory Committee on the
Readjustment of Veterans will be held
Tuesday, Wednesday and Thursday,
September 11, 12, and 13, 2018. The
meetings will be conducted at the
Department of Veterans Affairs National
Headquarters, at 811 Vermont Avenue
NW, Washington, DC 20420, in
Conference Room 6132. The agenda for
these three days will begin at 8:00 a.m.
and end at 4:30 p.m. The meetings are
open to the public.
The purpose of the Committee is to
review the post-war readjustment needs
of combat-theater Veterans and to
evaluate the availability, effectiveness
and coordination of VA programs
available to meet Veterans’ readjustment
service needs. The Committee reviews
issues related to promoting Veterans’
access to VA services, provision of
readjustment counseling services at Vet
Centers, and coordination of care
between the Vet Centers and VA
medical facilities.
On Tuesday, September 11, the
agenda will feature briefings from the
Readjustment Counseling Service (RCS)
Chief Officer regarding the current
activities of the RCS Vet Centers to
include the full scope of outreach and
readjustment counseling being provided
to combat-theater Veterans, Service
members and their families. The
briefing will also provide a status report
regarding the RCS organizational
transition to a single point of service
within the general organizational
transformation of the Veterans Health
Administration (VHA).
On Wednesday, September 12, the
Committee will focus on VA mental
health services and best practices for
coordinating VA mental health services
with RCS readjustment counseling
services to better serve the combat-
theater Veteran population. To this end
Committee members will receive
briefings from VA’s mental health
leadership on the types and distribution
of psychiatric disorders currently being
presented by OIF/OEF Veterans and the
various treatment regimens provided for
their care inclusive of psychotherapy
and psychopharmacology. VA Mental
Health and RCS leadership will
additionally present on the collaborative
activities currently underway between
RCS and the Office of Mental Health
and Suicide Prevention to achieve life-
saving outcomes for at risk combat-
theater Veterans and Service members.
On Thursday, September 13, the
Committee will engage in strategic
discussions for the purpose of
formulating conclusions, perspectives
and recommendations for developing its
20th annual report to Congress.
