Notice of workshop.


PHMSA is holding a workshop on the integrity assessment of cased pipe for pipelines subject to integrity management program requirements. The workshop is intended to discuss PHMSA's recently issued guidance “Guidelines for Integrity Assessment of Cased Pipe in Gas Transmission Pipelines” and related Frequently Asked Questions (FAQs). The latest guidelines and FAQs are available online at:​gasimp/​documents.htm. The workshop focus will be for the public, pipeline operators, trade associations, and others to address ideas and concerns with using External Corrosion Direct Assessment integrity evaluation methods and use of other technologies to assess pipelines in casings located within high consequence areas.

The workshop will be held at the Sheraton Inner Harbor, 300 South Charles Street, Baltimore, MD 21201 on April 28, 2010.


The April 28, 2010, cased pipe workshop will be held at the Sheraton Inner Harbor, 300 South Charles Street, Baltimore, MD 21201. The meeting room will be posted at the hotel on the day of the workshop.

Issue Description: Under section 14 of the Pipeline Safety and Improvement Act of 2002 (Pub. L. 107-355) and the regulations issued thereunder, all gas transmission pipelines located in areas that could affect high consequence areas (HCAs) must have an integrity management program (IMP). One aspect of an integrity management program is that each operator of a gas transmission pipeline located in an area that could affect a HCA must conduct an integrity assessment by an approved method no later than December 17, 2012, and must periodically reassess the pipeline at least every seven years thereafter.

In response to Congressional mandates, PHMSA promulgated integrity management regulations to implement this and other IMP requirements now contained in 49 CFR 192, Subpart O. These regulations requiring assessments apply to all pipe in a HCA, including cased pipe.

Operators reported that they were encountering technical challenges in conducting External Corrosion Direct Assessment (ECDA) on cased pipe and industry requested more detailed guidance from PHMSA. PHMSA responded by committing to hold a workshop to address the issues and to follow up with stakeholders to help address the challenges cased crossing pose. That workshop was held in July 2008 (​meetings/​MtgHome.mtg?​mtg=​64).

Following the workshop, PHMSA worked with a group of state regulators, representatives from industry, trade associations, and other stakeholders to develop guidelines for performing ECDA of gas transmission pipe inside casings (​gasimp/​ccCASQAT.htm). These guidelines are intended to assist pipeline operators in complying with 49 CFR 192, Subpart O for cased pipe in HCAs. The guidelines incorporate some of the input developed by this work group, but have been updated in some areas to conform to the integrity management regulations and statutory requirements.

The guidelines and FAQs are largely based on the work of this group and state regulators, and provide guidelines for pipeline operators to consider when implementing integrity management requirements for cased pipe. The casing guidelines should assist operators in cases where other integrity methods are not viable due to the pipeline being unpiggable for reasons such as lateral location and customer outage requirements.

Preliminary Workshop Agenda

The April 28, 2010 workshop will include:

(1) Briefing on the Guidelines for Integrity Assessment of Cased Pipe.

(2) Briefing on FAQs.

(3) Comments from Stakeholders.

(4) Question and Answer Forum.

Refer to the meeting Web site for a more detailed agenda:​meetings/​MtgHome.mtg?​mtg=​64. PHMSA encourages all interested persons to attend.
