Class Location Methodology Public Workshop

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is holding a public workshop to present and seek comment on whether applying the integrity management (IM) requirements beyond high consequence area (HCAs) would mitigate the need for class location requirements. Locations along gas pipelines are divided into classes from 1 (rural) to 4 (densely populated) and are based upon the number of buildings or dwellings for human occupancy. Allowable pipe operating stresses, as a percentage of specified minimum yield strength (SMYS), decrease as class location increases from Class 1 to Class 4 locations. Gas IMP requirements use a different approach to identify areas of higher risk along pipelines. The workshop will have presentations from PHMSA, State representatives and other stakeholders on the review of both methodologies, discussion panels, and an overview of comments received from August 1, 2013 Notice of Inquiry and from August 25, 2011 Advance Notice of Proposed Rulemaking (ANPRM) in Docket No. PHMSA-2011-0023 on www.regulations.gov.
