ATMOS PIPELINE - TEXAS — Integrity Assurance Notification

ALTERNATIVE PIPE SAMPLINGPursuant to §192.607(e)(5), Atmos Energy Corporation (Atmos Energy) is submitting this notification in accordance with §192.18 of its intent to use an alternative sampling approach. Section 192.607(e)(5) provides in relevant part: “An operator may use an alternative statistical sampling approach that differs from the requirements specified in paragraph (e)(2)” provided that the alternative sampling program “use[s] valid statistical bases designed to achieve at least a 95% confidence level that material properties used in the operation and maintenance of the pipeline are valid.” Enclosed with this notification is the Measuring Material Properties and Attributes and Delineating Populations Using ILI Procedure, which Atmos Energy intends to use to determine pipeline properties and attributes and to delineate pipeline populations in accordance with §192.607 using in-line inspection (ILI). In certain cases, as may be appropriate, this procedure also allows for using an alternative sampling approach to confirm pipeline material properties. Section 7 of this procedure sets forth the details surrounding the alternative sampling approach.#
