| Equity [Text Block] | EQUITY We had 68,926,453 common public units outstanding as of December 31, 2016. Additionally, Tesoro owned 34,055,042 of our common units, and 2,100,900 of our general partner units (the 2% general partner interest) as of December 31, 2016, which together constitutes a 34% ownership interest in us. UNIT ISSUANCE. We closed a registered public offering of 6,325,000 common units representing limited partner interests, including the over-allotment option exercised by the underwriter for the purchase of an additional 825,000 common units, at a public offering price of $47.13 per unit on June 10, 2016. The net proceeds of $293 million were used for general partnership purposes, including debt repayment, acquisitions, capital expenditures and additions to working capital. ATM PROGRAM. On June 25, 2014, we filed a prospectus supplement to our shelf registration statement filed with the SEC in 2012, authorizing the continuous issuance of up to an aggregate of $200 million of common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of our offerings (such continuous offering program, or at-the-market program, referred to as our “2014 ATM Program”). The 2014 ATM Program expired during the second quarter of 2015. During the years ended December 31, 2015 and 2014, we issued an aggregate of 819,513 and 199,400 common units under our 2014 ATM Program, generating proceeds of approximately $46 million and $14 million before issuance costs. On August 24, 2015, we filed a prospectus supplement to our shelf registration statement filed with the Securities and Exchange Commission on August 6, 2015, authorizing the continuous issuance of up to an aggregate of $750 million of common units, in amounts, at prices and on terms to be determined by market conditions and other factors at the time of our offerings (such continuous offering program, or at-the-market program, referred to as our “2015 ATM Program”). During the years ended December 31, 2016 and 2015, we issued an aggregate of 1,492,637 and 1,093,483 common units, respectively, under our 2015 ATM Program, generating proceeds of approximately $72 million and $57 million, respectively, before issuance costs. The net proceeds from issuances under the 2015 and 2014 ATM Programs were used for general partnership purposes, including debt repayment, acquisitions, capital expenditures and additions to working capital. ISSUANCE OF ADDITIONAL SECURITIES. Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities for the consideration and on the terms and conditions determined by our general partner without the approval of the unitholders. Costs associated with the issuance of securities are allocated to all unitholders’ capital accounts based on their ownership interest at the time of issuance. NET EARNINGS PER UNIT. Our partnership agreement contains provisions for the allocation of net earnings and loss to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss will be allocated among the partners in accordance with their respective percentage interest. Normal allocations according to percentage interests are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions fully allocated to the general partner and any special allocations.

INCENTIVE DISTRIBUTION RIGHTS. The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under marginal percentage interest in distributions are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute, up to and including the corresponding amount in the column total quarterly distribution per unit target amount. The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. For illustrative purposes, the percentage interests set forth below for our general partner assume that there are no arrearages on common units, our general partner has contributed any additional capital necessary to maintain its 2% general partner interest and our general partner owns all of the IDRs. PERCENTAGE ALLOCATION FOR INCENTIVE DISTRIBUTION RIGHTS
In connection with the North Dakota Gathering and Processing Assets acquisition, our general partner agreed to ratably reduce its quarterly distributions with respect to incentive distribution rights by $100 million with respect to distributions during 2017 and 2018. DISTRIBUTIONS FOR ACQUISITIONS. Distributions to unitholders and general partner include $760 million, $250 million, and $243 million in cash payments for acquisitions from Tesoro during 2016, 2015 and 2014, respectively. As an entity under common control with Tesoro, we record the assets that we acquire from Tesoro in our consolidated balance sheets at Tesoro’s historical book value instead of fair value, and any excess of amounts paid over the historical book value of the assets acquired from Tesoro is recorded within equity. As a result of this accounting treatment, these transactions resulted in net decreases of $443 million, $211 million and $214 million in our equity balance during 2016, 2015 and 2014, respectively. CASH DISTRIBUTIONS. Our partnership agreement, as amended, sets forth the calculation to be used to determine the amount and priority of cash distributions that the limited partner unitholders and general partner will receive. On January 18, 2017, in accordance with our partnership agreement, we announced the declaration of a quarterly cash distribution, based on the results of the fourth quarter of 2016, totaling $140 million, or $0.910 per limited partner unit. This distribution was paid on February 14, 2017 to unitholders of record on February 3, 2017. TOTAL QUARTERLY CASH DISTRIBUTIONS TO GENERAL AND LIMITED PARTNERS (in millions)
