The Pipeline and Hazardous Materials Safety Administrations (PHMSA) Integrity Management Inspection Protocols for hazardous liquid pipeline operators have been revised to reflect experience obtained during the first round of Integrity Management inspections. The inspection forms were updated in December 2004, and will be used beginning with the second round of Integrity Management inspections for hazardous liquid operators. An additional minor update was implemented in October 2006 to incorporate the external corrosion direct assessment (ECDA) rule change and add integrity management-related Annual Report data reviews. These protocols are being used to inspect operators for compliance with all aspects of the Integrity Management Rule §195.452. To help illustrate updates and organizational changes to the protocols, a cross-reference table table between the updated protocols and the protocol set used for the first round of Integrity Management inspections is also available.
