Guidelines for Integrity Assessment of Cased Pipe for Gas Transmission Pipelines in HCAs

Under the 2002 Pipeline Safety and Improvement Act, all gas transmission pipelines located in High Consequence Areas (HCAs) must have an integrity management program (IMP). One aspect of an integrity management program specifically mandated by Congress is that each gas transmission pipeline located in an HCA must have an integrity assessment by an approved method no later than December 17, 2012 and must be periodically reassessed at least every seven years thereafter.
