Related Party Transactions [Abstract] |
Related Party Transactions Disclosure | RELATED-PARTY TRANSACTIONS AFFILIATE AGREEMENTS The Partnership has various long-term, fee-based commercial agreements with Andeavor, under which we provide pipeline transportation, trucking, terminal distribution, and storage services to Andeavor. Andeavor typically commits to provide us with minimum monthly throughput volumes of crude oil and refined products. For the natural gas liquids that we handle under keep-whole agreements, the Partnership has a fee-based processing agreement with Andeavor which minimizes the impact of commodity price movements during the annual period subsequent to renegotiation of terms and pricing each year. In addition, we have agreements for the provision of various general and administrative services by Andeavor. Under our partnership agreement, we are required to reimburse TLGP and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended omnibus agreement (the “Amended Omnibus Agreement”) or our amended secondment agreement (the “Amended Secondment Agreement”), TLGP determines the amount of these expenses. The Amended Omnibus Agreement and the Amended Secondment Agreement were amended and restated in connection with the Alaska Storage and Terminalling Assets acquisition. Under the terms of the Amended Omnibus Agreement as of September 30, 2017, we are required to pay Andeavor an annual corporate services fee of $11 million for the provision of various centralized corporate services, including executive management, legal, accounting, treasury, human resources, health, safety and environmental, information technology, certain insurance coverage, administration and other corporate services. Andeavor charged the Partnership $6 million and $1 million pursuant to the Amended Secondment Agreement for the three months ended September 30, 2017 and 2016, respectively, and $16 million and $7 million for the nine months ended September 30, 2017 and 2016, respectively. Additionally, pursuant to the Amended Omnibus Agreement and Amended Secondment Agreement, we reimburse Andeavor for any direct costs actually incurred by Andeavor in providing other operational services with respect to certain of our other assets and operations. In conjunction with the WNRL Merger, certain agreements have been amended and are effective as of October 30, 2017.
