**body:**

In accordance with 49 CFR 192.714(e)(3) Acadian Gas Pipeline System conducted an integrity assessment via a Rosen MFL/DEF/IMU ILi tool inspection on 10/24/2024 for the LID 307-0300 AID 5487 - 8" Schriever to Leighton pipeline segment. The Rosen MFL/DEF/IMU ILi Preliminary Report was received on 12/9/2024. After reviewing the preliminary report, it was determined that twenty-four (24) anomalies reported as possible mechanical damage would require a temporary pressure reduction be issued. Prior to the temporary pressure reduction being issued, five (5) anomalies were investigated and repaired. A 10% temporary pressure reduction was implemented for the remaining nineteen (19) anomalies on 12/16/2024, to a reduced pressure of 207 psig.
