Start Preamble

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.)

SUPPLEMENTARY INFORMATION:

Introduction

The Federal pipeline safety regulations (49 CFR part 192 Subpart O; 49 CFR § 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.

Background

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.
