Segment and Related Information SEGMENT AND RELATED INFORMATION
DT Midstream sets strategic goals, allocates resources, and evaluates performance based on the following structure:
The Pipeline segment owns and operates interstate and intrastate natural gas pipelines, storage systems, and natural gas gathering lateral pipelines. The segment also has interests in equity method investees that own and operate interstate natural gas pipelines. The Pipeline segment is also engaged in the transportation and storage of natural gas for intermediate and end user customers. During the three months ended March 31, 2023, DT Midstream completed the conversion of the Michigan Gathering System and began providing services under a new long-term dry gas transmission contract. During the three months ended March 31, 2023, the Michigan Gathering System financial results are presented in the Pipeline segment. The prior period comparative activity was for gathering services and therefore was not revised.
The Gathering segment owns and operates gas gathering systems. The segment is engaged in collecting natural gas from points at or near customers’ wells for delivery to plants for treating, to gathering pipelines for further gathering, or to pipelines for transportation, as well as associated ancillary services, including compression, dehydration, gas treatment, water impoundment, water transportation, water disposal, and sand mining.
Inter-segment billing for goods and services exchanged between segments is based upon contracted prices of the provider. Inter-segment billings were not significant for the three months ended March 31, 2023 and 2022.
