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. 1 https://www.ntsb.gov/_layouts/ntsb.recsearch/ Recommendation.aspx?Rec=P-15-010. 2 https://www.ntsb.gov/_layouts/ntsb.recsearch/ Recommendation.aspx?Rec=P-15-012. 3 https://www.ntsb.gov/_layouts/ntsb.recsearch/ Recommendation.aspx?Rec=P-15-013.

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.
