Subsequent Events	26. SUBSEQUENT EVENTS On February 2, 2012, NuStar Logistics issued $250.0 million of 4.75% senior notes under our 2010 Shelf Registration Statement. The net proceeds of $247.5 million were used to repay the outstanding principal amount of the 7.75% senior notes due February 15, 2012. In connection with the new 4.75% senior notes, we terminated the related forward-starting interest rate swaps with a payment of $25.4 million. The interest on the 4.75% senior notes is payable semi-annually in arrears on February 1 and August 1 of each year beginning on August 1, 2012. The notes will mature on February 1, 2022. The 4.75% senior notes do not have sinking fund requirements. These notes rank equally with existing senior unsecured indebtedness of NuStar Logistics and contain restrictions on NuStar Logistics’ ability to incur secured indebtedness unless the same security is also provided for the benefit of holders of the senior notes. In addition, the senior notes limit NuStar Logistics’ ability to incur indebtedness secured by certain liens and to engage in certain sale-leaseback transactions. At the option of NuStar Logistics, the 4.75% senior notes may be redeemed in whole or in part at any time at a redemption price, which includes a make-whole premium, plus accrued and unpaid interest to the redemption date. The 4.75% senior notes are fully and unconditionally guaranteed by NuStar Energy and NuPOP.
