Welcome to the Gas Transmission Pipeline Integrity Management (IM) web site. This web site is designed to provide information to regulators and pipeline operators on Gas Integrity Management including the Gas IM NPRM (49 CFR Part 192, Subpart O) and information on the Pipeline and Hazardous Material Safety Administration's (PHMSA's) oversight (inspection and enforcement) of the Gas IM Rule.

The information on this site will continue to evolve to ensure that it represents the most up-to-date reference on Gas IM for regulators and operators. We are currently in the initial stage of implementing the oversight program. Information of particular interest to operators as they continue development and implementation of their IM programs include PHMSA inspection protocols, Frequently Asked Questions (FAQs), electronic forms for submitting required notifications to PHMSA, and electronic forms for submitting required periodic performance measures.
