**body:**

This notification is to satisfy the regulatory requirements of 49 C.F.R. § 195.452(h)(1)(ii) for a long-term pressure reduction regarding anomalous conditions discovered via an integrity assessment. Colonial Pipeline Company’s (Colonial) operator ID number is 2552. As explained in greater detail below, Colonial’s current pressure reduction on its Line 44-1 (Linden to Star Stratus) will exceed 365-days due to railroad permitting delays in the Linden, New Jersey area. Line 44-1 Linden to Star Stratus was inspected with MFL+CAL+IMU ILI technology on 10/28/2021. The ILI final report was received from the ILI vendor on 1/17/2022, after which, Colonial began analyzing the data. Based on Colonial’s analysis of the ILI data, 11 digs were issued on 04/22/2022. Of the 11 digs issued, 9 were metal loss digs and 2 were Type A to Type B sleeve conversions. All 11 digs were issued as 1-year digs, with a deadline of 04/22/2023.
