The Department of Transportation (DOT) publishes a Significant Rulemaking Report that reflects the revised dates for the Pipeline Hazardous Materials Safety Administration (PHMSA) rulemakings. A quick reference table for the pipeline safety regulations is provided below with a short description of each rulemaking after the table. The full report can be seen here: http://www.dot.gov/regulations/report-on-significant-rulemakings.
|PHMSA Rulemaking||Stage||Projected Publication Date|
|Liquid Hazardous Pipelines||Final Rule||December 30, 2016 (…not!)|
|Rupture Detection and Valves Rule||NPRM||May 3, 2017 (Comment Period Ends: July 3, 2017)|
|Gas Transmission (RRR)||Final Rule||December 11, 2017|
Hazardous Liquid Pipelines
[Docket No. PHMSA-2010-0229]
PHMSA published a Notice of Proposed Rulemaking (NPRM) in the Federal Register on October 13, 2015 to improve protection of the public, property, and the environment by closing regulatory gaps where appropriate, and ensuring that operators are increasing the detection and remediation of unsafe conditions, and mitigating the adverse effects of hazardous liquid pipeline failures.
Amendments to Parts 192 and 195 to require Valve installation and Minimum Rupture Detection Standards
[Docket No. (not assigned yet) / RIN 2137-AF06]
This rule would propose installation of automatic shutoff valves, remote controlled valves, or equivalent technology and establish performance based meaningful metrics for rupture detection for gas and liquid transmission pipelines. The overall intent is that rupture detection metrics will be integrated with Automatic Safety Valve (ASV) and Remote Control Valve (RCV) placement with the objective of improving overall incident response. Rupture response metrics would focus on mitigating large, unsafe, uncontrolled release events that have a greater potential consequence. The areas proposed to be covered include High Consequence Areas (HCA) for hazardous liquids and HCA, Class 3 and 4 for natural gas (including could affect areas).
