EGAN HUB STORAGE, LLC — Integrity Assurance Notification

PROGRAMEnbridge Gas Transmission and Midstream (GTM) is submitting this notification for significantly modifying its Integrity Management Program for onshore gas pipeline systems as presented in a meeting with PHMSA on March 31, 2020. Enbridge GTM notes in this communication that it does not operate offshore gas transmission or hazardous liquid pipeline systems that are subject to the integrity management requirements described by 49 CFR Part 192 Subpart O and 49 CFR § 195.452, respectively.This notification serves as the first formal notification that the Integrity Management Program for the Operator IDs described in this notice was significantly modified on May 31, 2020 as part of an ongoing project to consolidate and harmonize Enbridge GTM’s Program into a single, consistent program across all assets.  This program includes an overarching Asset Integrity Management Program (AIMP) document outlining management system requirements for all asset integrity programs (pipeline, facilities and storage).  Additionally, consolidated Pipeline Integrity Management Plan (P-IMP) and Facility Integrity Management Plan (F-IMP) documents were published to ensure a consistent approach to integrity management across all Enbridge GTM assets while still maintaining implementation of Subpart O requirements.  As part of the AIMP implementation, Enbridge GTM will be following up with a program change notification (pursuant to § 191.22) to incorporate additional OPIDs under the new AIMP.    Enbridge GTM will be updating procedures that address Subpart O requirements in the context of the new AIMP and the subsidiary P-IMP and F-IMP. These updated procedures are expected to be implemented in batches during the May 31, 2020 to December 31, 2020 time period.#
