Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES From time to time, DT Midstream is subject to legal, administrative and environmental proceedings before various courts, arbitration panels and governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, additional environmental reviews and investigations, audits and pending judicial matters. DT Midstream cannot predict the final disposition of such proceedings. DT Midstream regularly reviews legal matters and records provisions for claims that we can estimate and are considered probable of loss. The amount or range of reasonably possible losses is not anticipated to, either individually or in the aggregate, materially adversely affect DT Midstream’s business, financial condition and results of operations. Guarantees In certain limited circumstances, DT Midstream enters into contractual guarantees. DT Midstream may guarantee another entity's obligation in the event it fails to perform and may provide guarantees in certain indemnification agreements. DT Midstream did not have any guarantees of other parties' obligations as of March 31, 2023. Vector Pipeline Line of Credit DT Midstream is the lender under a revolving term credit facility to Vector Pipeline, the borrower, in the amount of Canadian $70 million. The credit facility was executed in response to the passage of Canadian regulations requiring oil and gas pipelines to demonstrate their financial ability to respond to a catastrophic event and exists for the sole purpose of satisfying these regulations. Vector Pipeline may only draw upon the facility if the funds are required to respond to a catastrophic event. The maximum potential payout at March 31, 2023 is USD $52 million. The funding of a loan under the terms of the credit facility is considered remote. Environmental Contingencies In order to comply with certain state environmental regulations, DT Midstream has an obligation to restore pipeline right-of-way slope failures that may arise in the ordinary course of business in the Utica and Marcellus formations. Slope restoration expenditures are typically capital in nature. As of both March 31, 2023 and December 31, 2022, DT Midstream had accrued contingent liabilities of $19 million for future slope restoration expenditures. The accrual is included in Other current liabilities and Other liabilities in the Consolidated Statements of Financial Position. DT Midstream believes the accrued amounts are sufficient to cover estimated future expenditures.
