CRESCENT MIDSTREAM, LLC — Integrity Assurance Notification

INTERVALCrescent Midstream is requesting an extension of the five-year integrity assessment interval for the LA-Delta1 and LA-Delta2 pipe segments per 49 CFR 195.452 U)(4)(ii) and Crescent's O&M Section 6.0. Crescent began planning the integrity assessment in April, but is unable to meet the "not to exceed" date of 12/09/2022 due to tool availability. This segment requires a dual diameter tool, and the earliest availability is late November. Furthermore, there are access limitations on the ROW from November through January due to waterfowl hunting season. Crescent is requesting to schedule an ILI tool for March or April 2023 post waterfowl season and to allow for more conducive weather conditions which impact water access. A Long Seam Crack Analysis was completed on LA-Delta1 and LA-Delta2 in September 2022 which concluded that there is no significant threat for the next 5 years based on the current operating parameters.#
