3. Acquisitions of Common Control Assets

On September 15, 2016, we completed the St. Paul Park Logistics Transaction with a wholly-owned subsidiary of Western in exchange for $195 million in cash and 628,224 common units representing limited partner interests in WNRL.

The St. Paul Park Logistics Assets acquired by WNRL included approximately 4.0 million barrels of refined product and crude oil storage capacity, a light products terminal, a heavy products loading rack and certain rail and barge facilities. The St. Paul Park Logistics Assets also include other related logistics assets including two crude oil pipeline segments and one pipeline segment not currently in service, each of which is 2.5 miles and extends from Western's refinery in St. Paul Park, Minnesota to Western's tank farm in Cottage Grove, Minnesota.

In connection with the St. Paul Park Logistics Transaction, we entered into a terminalling, transportation and storage services agreement with Western (the "St. Paul Park Terminalling Agreement"). Pursuant to the St. Paul Park Terminalling Agreement, we agreed to provide product storage services, product throughput services and product additive and blending services at the terminal facilities located at or near Western's refinery in St. Paul Park, Minnesota. In exchange for such services, Western agreed to certain minimum volume commitments and to pay certain fees. The St. Paul Park Terminalling Agreement has an initial term of ten years, which may be extended for up to two renewal terms of five years each upon the mutual agreement of the parties. See Note 17, Related Party Transactions, for additional information.
