CYPRESS INTERSTATE PIPELINE LLC — Integrity Assurance Notification

DISCOVERY BEYOND 180 DAYS HCAPursuant to 49 C.F.R. § 195.452(h)(1)(i) and as disclosed in an April 7, 2021 meeting with the Pipeline and Hazardous Materials Safety Administration (PHMSA), Kinder Morgan Inc. (KMI) is supplementing its disclosure with this integrity assurance notification. Based on recent PHMSA guidance regarding “corrosion of or along a longitudinal seam weld,” KMI is unable to complete the remediation of up to 2,715 180-day repair conditions on certain products pipelines within the schedule under 49 C.F.R. § 195.452(h)(4)(iii)(H) . The listed conditions are based on the latest applicable ILI runs. At the time that KMI received the final relevant inline inspection (ILI) data, KMI did not consider these conditions to require repair within 180 days through application of its integrity management program (IMP) consistent with prior PHMSA guidance.#
