Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	1. General Description of Business SunCoke Energy Partners, L.P., (the "Partnership", "we", "our", and "us"), is a Delaware limited partnership formed in July 2012 , which primarily produces coke used in the blast furnace production of steel. At September 30, 2016 , we owned a 98 percent interest in Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown") and Gateway Energy and Coke Company, LLC ("Granite City"). The remaining 2 percent ownership interest in our three cokemaking facilities was owned by SunCoke Energy, Inc. ("SunCoke"). We also own a Coal Logistics business, which provides coal handling and/or mixing services to third-party customers as well as to our own cokemaking facilities and other SunCoke cokemaking facilities. Our Coal Logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT") and SunCoke Lake Terminal, LLC ("Lake Terminal"). At September 30, 2016 , SunCoke, through a subsidiary, owned a 53.9 percent limited partnership interest in us and indirectly owned and controlled our general partner, which holds a 2.0 percent general partner interest in us and all of our incentive distribution rights ("IDR"). Incorporated in Delaware in 2012 and headquartered in Lisle, Illinois, we became a publicly-traded partnership in 2013 and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXCP.” Basis of Presentation The accompanying unaudited combined and consolidated financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP") for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the period ended September 30, 2016 are not necessarily indicative of the operating results for the full year. These unaudited interim combined and consolidated financial statements and notes should be read in conjunction with the audited combined and consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2015 . The combined and consolidated financial statements for the periods presented pertain to the operations of the Partnership and give retrospective effect to include the results of operations and cash flows of Granite City (the "Previous Owner"), as a result of the January 2015 dropdown of a 75 percent interest in Granite City ("Granite City Dropdown"). New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. The Partnership is currently evaluating this ASU to determine its potential impact on the Partnership's financial condition, results of operations, and cash flows. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting revenue gross versus net),” which clarifies gross versus net revenue reporting when another party is involved in the transaction. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing,” which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients," which provides narrow-scope improvements to the guidance on collectibility, non-cash consideration, and completed contracts at transition. The standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and permits early adoption on a limited basis. The Partnership is currently evaluating the new standard to determine its potential impact on the Partnership's financial condition, results of operations, and cash flows. Reclassifications Certain amounts in the prior period combined and consolidated financial statements have been reclassified to conform to the current year presentation.

Related Party Transactions [Abstract]
Related Party Transactions and Agreements	2. Related Party Transactions and Agreements Transactions with Affiliate Our Coal Logistics business provides coal handling and mixing services to certain SunCoke cokemaking operations. Coal Logistics recorded revenues derived from services provided to SunCoke’s cokemaking operations of $2.5 million and $7.7 million for the three and nine months ended September 30, 2016 , respectively, and $4.0 million and $10.3 million during the three and nine months ended September 30, 2015 , respectively. Additionally, Domestic Coke purchased coal from SunCoke and its affiliates totaling $1.6 million and $3.8 million during the three and nine months ended September 30, 2016 , respectively, and $1.3 million and $3.9 million during the three and nine months ended September 30, 2015 , respectively. Our Coal Logistics business also provides coal handling and storage services to Murray American Coal ("Murray") and Foresight Energy LP ("Foresight"), who are related parties with The Cline Group. The Cline Group currently owns a 10.3 percent interest in the Partnership, acquired as part of the CMT acquisition. Additionally, Murray also holds a significant interest in Foresight. Sales to Murray and Foresight accounted for $4.6 million , or 2.5 percent , and $15.0 million or 2.7 percent of the Partnership's sales and other operating revenue and were recorded in the Coal Logistics segment for the three and nine months ended September 30, 2016 , respectively. During the three and nine months ended September 30, 2015, Coal Logistics recorded revenues derived from services provided to these related parties of $4.4 million . At September 30, 2016 , receivables from Murray and Foresight were $11.6 million , which were recorded in receivables on the Consolidated Balance Sheets, and deferred revenue for minimum volume shortfall payments was $25.7 million , which was recorded in deferred revenue on the Consolidated Balance Sheets. Deferred revenue on these take-or-pay contracts is billed quarterly, but recognized into income at the earlier of when service is provided or annually based on the terms of the contract. At December 31, 2015, receivables from Murray and Foresight were $7.2 million , which were recorded in receivables on the Consolidated Balance Sheets, and there were no deferred revenues for minimum volume shortfall payments from these customers. In connection with the acquisition of CMT, the Partnership assumed Raven Energy LLC's promissory note ("Promissory Note") of $114.9 million with a subsidiary of The Cline Group as the lender. See Note 7 . Additionally, as part of the acquisition of CMT, the Partnership entered into a contingent consideration agreement with The Cline Group. See Note 10 . Also as part of the CMT acquisition, the Partnership withheld $21.5 million in cash to fund the completion of capital improvements at CMT. The cash withheld was recorded as restricted cash on the Consolidated Balance Sheets. During the first quarter of 2016, the Partnership amended an agreement with the Cline Group, which unrestricted $6.0 million of the restricted cash and relieved any obligation of the Partnership to repay these amounts to The Cline Group. The remaining restricted cash balance as of September 30, 2016 of $0.7 million is primarily related to the completion of the installation of the new state-of-the-art ship loader, which is expected to be placed into service during the fourth quarter of 2016 and will allow for faster coal loading onto larger ships. Allocated Expenses SunCoke charges us for all direct costs and expenses incurred on our behalf and allocated costs associated with support services provided to our operations. Allocated expenses from SunCoke for general corporate and operations support costs totaled $6.5 million and $20.4 million for the three and nine months ended September 30, 2016 , respectively, and $6.5 million and $19.8 million during three and nine months ended September 30, 2015 , respectively, and were included in selling, general and administrative expenses on the Combined and Consolidated Statements of Income. These costs include legal, accounting, tax, treasury, engineering, information technology, insurance, employee benefit costs, communications, human resources, and procurement. Corporate allocations are recorded in accordance with the terms of our omnibus agreement with SunCoke and our general partner. These allocations were increased in the first quarter of 2016 for additional support provided to the CMT operations. In the first half of 2016, SunCoke took certain actions to support the Partnership's strategy to de-lever its balance sheet and maintain a solid liquidity position. During the first quarter of 2016, SunCoke provided a "reimbursement holiday" on the $7.0 million of corporate costs allocated to the Partnership and also returned its $1.4 million IDR cash distribution to the Partnership ("IDR giveback"), resulting in capital contributions of $8.4 million . During the second quarter of 2016, SunCoke provided the Partnership with deferred payment terms until April 2017 on the reimbursement of the $6.9 million of allocated corporate costs to the Partnership and the $1.4 million IDR cash distribution, resulting in an outstanding payable to SunCoke of $8.3 million included in payable to affiliate, net on the Consolidated Balance Sheets as of September 30, 2016 . At September 30, 2016 , net payables to SunCoke and affiliates were $6.2 million , which were recorded in payable to affiliates, net on the Consolidated Balance Sheets. At December 31, 2015, net receivables from SunCoke and affiliates were $1.4 million , which were recorded in receivable from affiliates, net on the Consolidated Balance Sheets. Omnibus Agreement In connection with the closing of our initial public offering on January 24, 2013 ("IPO"), we entered into an omnibus agreement with SunCoke and our general partner that addresses certain aspects of our relationship with them, including: Business Opportunities. We have preferential rights to invest in, acquire and construct cokemaking facilities in the United States and Canada. SunCoke has preferential rights to all other business opportunities. Potential Defaults by Coke Agreement Counterparties. For a period of five years from the closing date of the IPO, SunCoke has agreed to make us whole (including an obligation to pay for coke) to the extent (i) AK Steel exercises the early termination right provided in its Haverhill coke sales agreement, (ii) any customer fails to purchase coke or defaults in payment under its coke sales agreement (other than by reason of force majeure or our default) or (iii) we amend a coke sales agreement's terms to reduce a customer's purchase obligation as a result of the customer's financial distress. We and SunCoke will share in any damages and other amounts recovered from third-parties arising from such events in proportion to our relative losses. Environmental Indemnity. SunCoke will indemnify us to the full extent of any remediation losses at the Haverhill and Middletown cokemaking facilities arising from any environmental matter discovered and identified as requiring remediation prior to the closing of the IPO. In addition, SunCoke will indemnify us for remediation losses at the Granite City cokemaking facility arising from any environmental matter discovered and identified as requiring remediation prior to the closing of the initial Granite City Dropdown. SunCoke contributed $67.0 million in partial satisfaction of this obligation from the proceeds of the IPO, and an additional $52.0 million in connection with subsequent dropdowns. If, prior to the fifth anniversary of the closing of the IPO, a pre-existing environmental matter is identified as requiring remediation, SunCoke will indemnify us for up to $50.0 million of any such remediation costs (we will bear the first $5.0 million of any such costs). Other Indemnification. SunCoke will fully indemnify us with respect to any additional tax liability related to periods prior to or in connection with the closing of the IPO or the Granite City Dropdown to the extent not currently presented on the Consolidated Balance Sheets. Additionally, SunCoke will either cure or fully indemnify us for losses resulting from any material title defects at the properties owned by the entities acquired in connection with the closing of the IPO or the Granite City Dropdown to the extent that those defects interfere with or could reasonably be expected to interfere with the operations of the related cokemaking facilities. We will indemnify SunCoke for events relating to our operations except to the extent that we are entitled to indemnification by SunCoke. License. SunCoke has granted us a royalty-free license to use the name “SunCoke” and related marks. Additionally, SunCoke has granted us a non-exclusive right to use all of SunCoke's current and future cokemaking and related technology. We have not paid and will not pay a separate license fee for the rights we receive under the license. Expenses and Reimbursement. SunCoke will continue to provide us with certain corporate and other services, and we will reimburse SunCoke for all direct costs and expenses incurred on our behalf and a portion of corporate and other costs and expenses attributable to our operations. SunCoke may consider providing additional support to the Partnership in the future by providing a corporate cost reimbursement holiday, whereby the Partnership would not be required to reimburse SunCoke for costs or a deferral, whereby the Partnership would be granted extended payment terms. Additionally, we have agreed to pay all fees in connection with any future financing arrangement entered into for the purpose of replacing the credit facility or the senior notes. So long as SunCoke controls our general partner, the omnibus agreement will remain in full force and effect unless mutually terminated by the parties. If SunCoke ceases to control our general partner, the omnibus agreement will terminate, but our rights to indemnification and use of SunCoke's existing cokemaking and related technology will survive. The omnibus agreement can be amended by written agreement of all parties to the agreement, but we may not agree to any amendment that would, in the reasonable discretion of our general partner, be adverse in any material respect to the holders of our common units without prior approval of the conflicts committee.

Cash Distributions and Net Income Per Unit	3. Cash Distributions and Net Income Per Unit Cash Distributions Our partnership agreement generally provides that we will make cash distributions, if any, each quarter in the following manner: • first , 98 percent to the holders of common units and 2 percent to our general partner, until each common unit has received the minimum quarterly distribution of $0.412500 plus any arrearages from prior quarters; • second, 98 percent to the holders of subordinated units and 2 percent to our general partner, until each subordinated unit has received the minimum quarterly distribution of $0.412500 ; and • third, 98 percent to all unitholders, pro rata, and 2 percent to our general partner, until each unit has received a distribution of $0.474375 . If cash distributions to our unitholders exceed $0.474375 per unit in any quarter, our unitholders and our general partner will receive distributions according to the following percentage allocations: Total Quarterly Distribution Per Unit Target Amount Marginal Percentage Interest in Distributions Unitholders General Partner Minimum Quarterly Distribution $0.412500 98% 2% First Target Distribution above $0.412500 up to $0.474375 98% 2% Second Target Distribution above $0.474375 up to $0.515625 85% 15% Third Target Distribution above $0.515625 up to $0.618750 75% 25% Thereafter above $0.618750 50% 50% Our distributions are declared subsequent to quarter end.

The total cash disbursed from the distribution on June 1, 2016 was $28.0 million . (2) On October 18, 2016 , our Board of Directors declared a cash distribution of $0.5940 per unit, which will be paid on December 1, 2016 , to unitholders of record on November 15, 2016 . Allocation of Net Income Our partnership agreement contains provisions for the allocation of net income to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall 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 allocated 100 percent to the general partner. Net income from Granite City’s operations prior to the Granite City Dropdown is allocated to the general partner. Upon payment of the cash distribution for the fourth quarter of 2015, the financial requirements for the conversion of all subordinated units were satisfied. As a result, the 15,709,697 subordinated units converted into common units on a one-for-one basis. For purpose of calculating net income per unit, the conversion of the subordinated units is deemed to have occurred on January 1, 2016. The conversion did not impact the amount of the cash distribution paid or the total number of the Partnership's outstanding units representing limited partner interest. The calculation of net income allocated to the general and limited partners was as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (Dollars in millions) Net income attributable to SunCoke Energy L.P./Previous Owner $ 21.3 $ 19.5 $ 73.2 $ 49.7 Less: Expenses allocated to Common - SunCoke (1) — — (7.0 ) — Less: Allocation of net income attributable to the Previous Owner to the general partner — — — 0.6 Net income attributable to all partners 21.3 19.5 80.2 49.1 General partner's incentive distribution rights 1.4 1.6 12.2 3.6 Net income attributable to partners, excluding incentive distribution rights 19.9 17.9 68.0 45.5 General partner's ownership interest: 2.0 % 2.0 % 2.0 % 2.0 % General partner's allocated interest in net income 0.4 0.3 1.4 0.9 General partner's incentive distribution rights 1.4 1.6 12.2 3.6 Net income attributable to the Previous Owner — — — 0.6 Total general partner's interest in net income $ 1.8 $ 1.9 $ 13.6 $ 5.1 Common - public unitholder's interest in net income $ 8.8 $ 7.7 $ 29.9 $ 19.3 Common - SunCoke interest in net income: Common - SunCoke interest in net income 10.7 3.4 36.7 8.0 Expenses allocated to Common - SunCoke (1) — — (7.0 ) — Total common - SunCoke interest in net income 10.7 3.4 29.7 8.0 Subordinated - SunCoke interest in net income — 6.5 — 17.3 Total limited partners' interest in net income $ 19.5 $ 17.6 $ 59.6 $ 44.6 (1) Per the amended Partnership agreement, expenses paid on behalf of the Partnership are to be allocated entirely to the partner who paid them. During the first quarter of 2016 , SunCoke paid $7.0 million of allocated corporate costs on behalf of the Partnership and will not seek reimbursement for those costs. See Note 2 . These expenses are recorded as a direct reduction to SunCoke's interest in net income for the nine months ended September 30, 2016 . Earnings Per Unit Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. In addition to the common and subordinated units, we also have identified the general partner interest and IDRs as participating securities and we use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Basic and diluted net income per unit applicable to limited partners are the same because we do not have any potentially dilutive units outstanding. In 2015, the Partnership early adopted ASU 2015-06, "Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions (a consensus of the Emerging Issues Task Force)." Therefore, the Granite City Dropdown does not impact historical earnings per unit as the earnings of Granite City prior to the Granite City Dropdown were allocated entirely to our general partner. The calculation of earnings per unit is as follows: Three Months Ended September 30, Nine months ended September 30, 2016 2015 2016 2015 (Dollars and units in millions, except per unit amounts) Net income attributable to SunCoke Energy L.P./Previous Owner $ 21.3 $ 19.5 $ 73.2 $ 49.7 Less: Expenses allocated to Common - SunCoke — — (7.0 ) — Less: Allocation of net income attributable to the Previous Owner to the general partner — — — 0.6 Net income attributable to all partners 21.3 19.5 80.2 49.1 General partner's distributions (including, $1.4, $1.6, $12.2 and $3.6 million of incentive distribution rights, respectively) 2.0 2.0 6.0 5.2 Limited partners' distributions on common units 27.5 18.2 82.4 49.6 Limited partners' distributions on subordinated units — 9.4 — 27.6 Distributions less than (greater than) earnings (8.2 ) (10.1 ) (8.2 ) (33.3 ) General partner's earnings: Distributions (including $1.4, $1.6, $12.2 and $3.6 million of cash incentive distribution rights, respectively) 2.0 2.0 6.0 5.2 Allocation of distributions less than (greater than) earnings (0.2 ) (0.1 ) 7.6 (0.7 ) Net income attributable to Previous Owner — — — 0.6 Total general partner's earnings 1.8 1.9 13.6 5.1 Limited partners' earnings on common units: Distributions 27.5 18.2 82.4 49.6 Expenses allocated to Common - SunCoke — — (7.0 ) — Allocation of distributions less than (greater than) earnings (8.0 ) (6.6 ) (15.8 ) (20.9 ) Total limited partners' earnings on common units 19.5 11.6 59.6 28.7 Limited partners' earnings on subordinated units: Distributions — 9.4 — 27.6 Allocation of distributions greater than earnings — (3.4 ) — (11.7 ) Total limited partners' earnings on subordinated units — 6.0 — 15.9 Weighted average limited partner units outstanding: Common - basic and diluted 46.2 27.4 46.2 24.8 Subordinated - basic and diluted — 15.7 — 15.7 Net income per limited partner unit: Common - basic and diluted $ 0.42 $ 0.43 $ 1.29 $ 1.16 Subordinated - basic and diluted $ — $ 0.38 $ — $ 1.00 Unit Activity Unit activity for the nine months ended September 30, 2016 : Common - Public Common - SunCoke Total Common Subordinated - SunCoke At December 31, 2015 20,787,744 9,705,999 30,493,743 15,709,697 Units issued to directors 9,720 — 9,720 — Conversion of subordinate units to common units — 15,709,697 15,709,697 (15,709,697 ) At September 30, 2016 20,797,464 25,415,696 46,213,160 —

Goodwill and Other Intangible Assets	5. Goodwill and Other Intangible Assets Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. Goodwill allocated to the Partnership's reportable segments as of September 30, 2016 and changes in the carrying amount of goodwill during the nine months ended September 30, 2016 were as follows: Coal Logistics (Dollars in millions) Net balance at December 31, 2015 $ 67.7 Adjustments (1)(2) 5.8 Net balance at September 30, 2016 $ 73.5 (1) In the first quarter of 2016, a working capital adjustment to the acquisition date fair value of the acquired net assets decreased the amount of the purchase price allocated to goodwill by $0.6 million . (2) In the third quarter of 2016, an adjustment to the acquisition date fair value of the contingent consideration liability increased the amount of the purchase price allocated to goodwill by $6.4 million .

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes The Partnership is a limited partnership and generally is not subject to federal income taxes. However, as part of the Granite City Dropdown in the first quarter of 2015, the Partnership acquired an interest in Gateway Cogeneration Company, LLC, which is subject to income taxes for federal and state purposes. Additionally, as a result of the Granite City Dropdown, the Partnership is subject to state income tax. Earnings from our Middletown operations are subject to a local income tax. The Partnership recorded income tax expense of $0.4 million and $1.4 million for the three and nine months ended September 30, 2016 , compared to income tax expense of $0.5 million for the three months ended September 30, 2015 and income tax benefit of $2.4 million for the nine months ended September 30, 2015 . The nine months ended September 30, 2015 included an income tax benefit of $4.0 million related to the tax impacts of the Granite City Dropdown. Earnings from our Granite City operations include federal and state income taxes calculated on a theoretical separate-return basis until the date of the Granite City Dropdown on January 13, 2015 . The Internal Revenue Service has commenced an audit on the Partnership's 2013 tax return. Although no assurance can be given, the Partnership does not anticipate any material changes in prior year taxable income as a result of the audit.

Debt Disclosure [Abstract]
Debt and Financing Obligation	7. Debt and Financing Obligation Total debt and financing obligation, including the current portion of long-term debt and financing obligation, consisted of the following: September 30, 2016 December 31, 2015 (Dollars in millions) 7.375% senior notes, due 2020 ("Partnership Notes") $ 468.1 $ 552.5 Revolving credit facility, due 2019 ("Partnership Revolver") 177.0 182.0 Promissory note payable, due 2021 ("Promissory Note") 113.5 114.3 Partnership's term loan, due 2019 ("Partnership Term Loan") 50.0 50.0 5.82% financing obligation, due 2021 ("Financing Obligation") 15.7 — Total borrowings 824.3 898.8 Original issue premium 8.2 12.1 Debt issuance cost (11.3 ) (15.3 ) Total debt and financing obligation 821.2 895.6 Less: current portion of long-term debt and financing obligation 3.6 1.1 Total long-term debt and financing obligation $ 817.6 $ 894.5 Partnership Notes During the nine months ended September 30, 2016, the Partnership continued de-levering its balance sheet and repurchased $84.4 million face value of outstanding Partnership Notes for $60.0 million of cash payments. This resulted in a gain on extinguishment of debt of $24.9 million during the nine months ended September 30, 2016 , which included the write-off of $0.5 million of unamortized original issue premium, net of unamortized debt issuance costs. Partnership Revolver The Partnership repaid $5.0 million on the Partnership Revolver during the third quarter of 2016 and at September 30, 2016 had $1.5 million of letters of credit outstanding and an outstanding balance of $177.0 million , leaving $71.5 million available. Subsequent to September 30, 2016 , on October 4, 2016, the Partnership repaid an additional $5.0 million on the Partnership Revolver. Financing Obligation On July 22, 2016 , the Partnership entered into a sale-leaseback arrangement of certain integral equipment from the Domestic Coke segment and certain mobile equipment from the Coal Logistics segment for total proceeds of $16.2 million . The leaseback agreement has an initial lease period of 60 months , with an early buyout option after 48 months to purchase the equipment at 34.5 percent of the original lease equipment cost. Under Accounting Standards Codification ("ASC") 840 "Leases", the early buyout option results in a form of continuing involvement by the Partnership, and therefore the arrangement is accounted for as a financing transaction. The Partnership repaid $0.5 million of the financing obligation during the third quarter of 2016. Annual future minimum lease payments are approximately $2.5 million to $3.0 million through 2019 and $7.3 million in 2020 , which includes the early buyout option payment. Covenants The Partnership is subject to certain debt covenants that, among other things, limit the Partnership’s ability, and the ability of certain of the Partnership’s subsidiaries, to (i) incur indebtedness, (ii) pay dividends or make other distributions, (iii) prepay, redeem or repurchase certain debt, (iv) make loans and investments, (v) sell assets, (vi) incur liens, (vii) enter into transactions with affiliates and (viii) consolidate or merge. These covenants are subject to a number of exceptions and qualifications set forth in the respective agreements governing the Partnership's debt. Under the terms of the Partnership Revolver, the Partnership is subject to a maximum consolidated leverage ratio of 4.50 : 1.00 , calculated by dividing total debt by EBITDA as defined by the Partnership Revolver, and a minimum consolidated interest coverage ratio of 2.50 : 1.00 , calculated by dividing EBITDA by interest expense as defined by the Partnership Revolver. Under the terms of the promissory agreement, Raven Energy LLC, a wholly-owned subsidiary of the Partnership, is subject to a maximum leverage ratio of 5.00 : 1.00 for any fiscal quarter ending prior to August 12, 2018, calculated by dividing total debt by EBITDA as defined by the promissory agreement. For any fiscal quarter ending on or after August 12, 2018, the maximum leverage ratio is 4.50 : 1.00 . Additionally in order to make restricted payments, Raven Energy LLC is subject to a fixed charge ratio of greater than 1.00 : 1.00 , calculated by dividing EBITDA by fixed charges as defined by the promissory agreement. If we fail to perform our obligations under these and other covenants, the lenders' credit commitment could be terminated and any outstanding borrowings, together with accrued interest, under the Partnership Revolver could be declared immediately due and payable. The Partnership has a cross-default provision that applies to our indebtedness having a principal amount in excess of $20 million . As of September 30, 2016 , the Partnership was in compliance with all applicable debt covenants contained in the Partnership Revolver and promissory agreement. We do not anticipate violation of these covenants nor do we anticipate that any of these covenants will restrict our operations or our ability to obtain additional financing.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	9. Commitments and Contingent Liabilities The United States Environmental Protection Agency (the "EPA") has issued Notices of Violations (“NOVs”) for the Haverhill and Granite City cokemaking facilities which stem from alleged violations of air operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent degree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment that was paid by SunCoke in December 2014, as well as capital projects already underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City cokemaking facilities. We retained an aggregate of $119 million in proceeds from the IPO, the dropdown of Haverhill and Middletown and the Granite City Dropdown to fund these environmental remediation projects at the Haverhill and Granite City cokemaking facilities. Pursuant to the omnibus agreement, any amounts that we spend on these projects in excess of the $119 million will be reimbursed by SunCoke. Prior to our formation, SunCoke spent $7 million related to these projects. We have spent approximately $85 million to date and the remaining capital is expected to be spent through the first quarter of 2019 . The Partnership is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and general environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Partnership. Management of the Partnership believes that any liability which may arise from claims would not have a material adverse impact on our combined and consolidated financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	10. Fair Value Measurements The Partnership measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. • Level 2—inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability. • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Certain assets and liabilities are measured at fair value on a recurring basis. The Partnership’s cash equivalents are measured at fair value based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy. The Partnership had $0.1 million of cash equivalents at September 30, 2016 . Convent Marine Terminal Contingent Consideration In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires us to make future payments to The Cline Group based on future volume over a specified threshold, price, and contract renewals. The fair value of the contingent consideration was estimated based on a probability-weighted analysis using significant inputs that are not observable in the market, or Level 3 inputs. Key assumptions included probability adjusted levels of coal handling services provided by CMT, anticipated price per ton on future sales and probability of contract renewal, including length of future contracts, volume commitment, and anticipated price per ton. The fair value of the contingent consideration at September 30, 2016 and December 31, 2015 was $6.0 million and $7.9 million , and was included in other deferred charges and liabilities on the Consolidated Balance Sheets. During the third quarter of 2016, the Partnership recorded an adjustment to the acquisition date fair value of the contingent consideration liability, which increased the liability and goodwill by $6.4 million . During the first quarter of 2016, the Partnership amended the contingent consideration terms with The Cline Group. These amended terms and subsequent fair value adjustments to the contingent consideration decreased costs of products sold and operating expenses on the Combined and Consolidated Statement of Income by $4.6 million and $8.3 million during the three and nine months ended September 30, 2016 , respectively. Deferred Compensation The Partnership offers its Board of Directors the opportunity to defer their unit-based compensation. The Partnership measures the fair value of the deferred compensation on a quarterly basis using the Partnership's closing unit price as of the end of the period, or Level 1 inputs. The fair value of the Board of Directors deferred compensation was $1.3 million and $0.4 million as of September 30, 2016 and December 31, 2015 , respectively, and was included in other deferred credits and liabilities on the Consolidated Balance Sheets. The fair value adjustments increased selling, general and administrative expenses by $0.4 million and $0.7 million during the three and nine months ended September 30, 2016, respectively and decreased selling, general and administrative expenses by $0.1 million and $0.4 million during the three and nine months ended September 30, 2015, respectively. Certain Financial Assets and Liabilities not Measured at Fair Value At September 30, 2016 , the estimated fair value of the Partnership's total debt was $792.5 million compared to a carrying amount of $ 824.3 million . The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions which are considered Level 2 inputs.

Business Segment Disclosures

Segment Reporting [Abstract]
Business Segment Disclosures	11. Business Segment Disclosures The Partnership derives its revenues from the Domestic Coke and Coal Logistics reportable segments. Domestic Coke operations are comprised of the Haverhill and Middletown cokemaking facilities located in Ohio and the Granite City cokemaking facility located in Illinois. These facilities use similar production processes to produce coke and to recover waste heat that is converted to steam or electricity. Steam is provided to third-party customers primarily pursuant to steam supply and purchase agreements. Electricity is sold into the regional power market or to AK Steel pursuant to energy sales agreements. Coke sales at the Partnership's cokemaking facilities are made pursuant to long-term, take-or-pay agreements with ArcelorMittal, AK Steel and U.S. Steel. Each of the coke sales agreements contain pass-through provisions for costs incurred in the cokemaking process, including coal procurement costs (subject to meeting contractual coal-to-coke yields), operating and maintenance expenses, costs related to the transportation of coke to the customers, taxes (other than income taxes) and costs associated with changes in regulation, in addition to containing a fixed fee. Coal Logistics operations are comprised of CMT located in Louisiana, Lake Terminal located in Indiana and KRT located in West Virginia. This business has a collective capacity to mix and transload approximately 35 million tons of coal annually and provides coal handling and/or mixing services to third-party customers as well as our own cokemaking facilities and other SunCoke cokemaking facilities. Coal handling and mixing results are presented in the Coal Logistics segment. Corporate and other expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other. Interest expense, net and (gain) loss on extinguishment of debt are also excluded from segment results. Segment assets are those assets that are utilized within a specific segment. The following table includes Adjusted EBITDA, which is the measure of segment profit or loss and liquidity reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (Dollars in millions) Sales and other operating revenue: Domestic Coke $ 170.8 $ 192.4 $ 517.2 $ 581.1 Coal Logistics 14.7 17.8 44.2 40.0 Coal Logistics intersegment sales 1.5 1.7 4.7 5.0 Elimination of intersegment sales (1.5 ) (1.7 ) (4.7 ) (5.0 ) Total sales and other operating revenue $ 185.5 $ 210.2 $ 561.4 $ 621.1 Adjusted EBITDA: Domestic Coke $ 42.9 $ 46.6 $ 130.3 $ 137.3 Coal Logistics 7.0 9.3 18.2 16.9 Corporate and Other (4.2 ) (5.2 ) (12.9 ) (10.5 ) Total Adjusted EBITDA $ 45.7 $ 50.7 $ 135.6 $ 143.7 Depreciation and amortization expense: Domestic Coke $ 12.7 $ 13.5 $ 38.7 $ 39.8 Coal Logistics (1) 5.4 3.5 18.6 7.2 Total depreciation and amortization expense $ 18.1 $ 17.0 $ 57.3 $ 47.0 Capital expenditures: Domestic Coke $ 4.4 $ 14.7 $ 15.8 $ 30.4 Coal Logistics 3.6 0.8 14.3 1.3 Total capital expenditures $ 8.0 $ 15.5 $ 30.1 $ 31.7 (1) The Partnership revised the estimated useful lives of certain assets in its Coal Logistics segment, which resulted in additional depreciation of $2.2 million , or $0.05 per common unit, during the nine months ended September 30, 2016. The following table sets forth the Partnership’s total sales and other operating revenue by product or service, excluding intersegment revenues: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (Dollars in millions) Sales and other operating revenue: Cokemaking revenues $ 155.8 $ 176.9 $ 471.3 $ 534.0 Energy revenues 13.9 15.5 42.5 47.0 Coal logistics revenues 14.2 17.2 43.2 38.7 Other revenues 1.6 0.6 4.4 1.4 Total revenues $ 185.5 $ 210.2 $ 561.4 $ 621.1 The following table sets forth the Partnership's segment assets: September 30, 2016 December 31, 2015 (Dollars in millions) Segment assets: Domestic Coke $ 1,192.0 $ 1,233.1 Coal Logistics 519.7 534.6 Corporate and Other 0.8 1.2 Total assets $ 1,712.5 $ 1,768.9 The Partnership evaluates the performance of its segments based on segment Adjusted EBITDA, which represents earnings before interest, (gain) loss on extinguishment of debt, taxes, depreciation and amortization, adjusted for Coal Logistics changes to our contingent consideration liability related to our acquisition of the CMT and the expiration of certain acquired contractual obligations. Adjusted EBITDA does not represent and should not be considered an alternative to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance and liquidity of the Partnership's net assets and its ability to incur and service debt, fund capital expenditures and make distributions. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance and liquidity. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered an alternative to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. Set forth below is additional discussion of the limitations of Adjusted EBITDA as an analytical tool. Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA: • does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; • does not reflect items such as depreciation and amortization; • does not reflect changes in, or cash requirements for, working capital needs; • does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt; • does not reflect certain other non-cash income and expenses; • excludes income taxes that may represent a reduction in available cash; and • includes net income attributable to noncontrolling interests. Below is a reconciliation of Adjusted EBITDA (unaudited) to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 (1) 2016 (1) 2015 (1) (Dollars in millions) Net cash provided by operating activities $ 31.9 $ 15.7 $ 140.0 $ 88.2 Subtract: Depreciation and amortization expense 18.1 17.0 57.3 47.0 (Gain) loss on extinguishment of debt (1.0 ) — (24.9 ) 9.4 Changes in working capital and other (7.2 ) (22.1 ) 32.5 (23.5 ) Net income $ 22.0 $ 20.8 $ 75.1 $ 55.3 Add: Depreciation and amortization expense $ 18.1 $ 17.0 $ 57.3 $ 47.0 Interest expense, net 11.5 12.4 35.7 34.4 (Gain) loss on extinguishment of debt (1.0 ) — (24.9 ) 9.4 Income tax expense (benefit), net 0.4 0.5 1.4 (2.4 ) Contingent consideration adjustments (2) (4.6 ) — (8.3 ) — Non-cash reversal of acquired contractual obligation (3) (0.7 ) — (0.7 ) — Adjusted EBITDA $ 45.7 $ 50.7 $ 135.6 $ 143.7 Subtract: Adjusted EBITDA attributable to Previous Owner (4) $ — $ — $ — $ 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 0.9 1.9 2.6 7.5 Adjusted EBITDA attributable to SunCoke Energy Partners, L.P. $ 44.8 $ 48.8 $ 133.0 $ 134.7 (1) Beginning in the second quarter of 2016, in response to the SEC’s May 2016 update to its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA no longer includes Coal Logistics deferred revenue until it is recognized as GAAP revenue. (2) The Partnership amended the contingent consideration terms with The Cline Group during the first quarter of 2016. These amendments and subsequent fair value adjustments resulted in gains of $4.6 million and $8.3 million recorded during the three and nine months ended September 30, 2016, respectively, which were excluded from Adjusted EBITDA. (3) In association with the acquisition of CMT, we assumed certain performance obligations under existing contracts and recorded liabilities related to such obligations. In third quarter of 2016, the final acquired contractual performance obligation expired without the customer requiring performance. As such, the Partnership reversed the liability in the period as we no longer have any obligations under the contract. (4) Reflects net income attributable to our Granite City facility prior to the Granite City Dropdown on January 13, 2015 adjusted for Granite City's share of interest, taxes, depreciation and amortization during the same period.

New Accounting Pronouncements	New Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. It is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. The Partnership is currently evaluating this ASU to determine its potential impact on the Partnership's financial condition, results of operations, and cash flows. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting revenue gross versus net),” which clarifies gross versus net revenue reporting when another party is involved in the transaction. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing,” which amends the revenue guidance on identifying performance obligations and accounting for licenses of intellectual property. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients," which provides narrow-scope improvements to the guidance on collectibility, non-cash consideration, and completed contracts at transition. The standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and permits early adoption on a limited basis. The Partnership is currently evaluating the new standard to determine its potential impact on the Partnership's financial condition, results of operations, and cash flows.

Reconciliation of Operating Profit (Loss) from Segments to Consolidated	Below is a reconciliation of Adjusted EBITDA (unaudited) to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 (1) 2016 (1) 2015 (1) (Dollars in millions) Net cash provided by operating activities $ 31.9 $ 15.7 $ 140.0 $ 88.2 Subtract: Depreciation and amortization expense 18.1 17.0 57.3 47.0 (Gain) loss on extinguishment of debt (1.0 ) — (24.9 ) 9.4 Changes in working capital and other (7.2 ) (22.1 ) 32.5 (23.5 ) Net income $ 22.0 $ 20.8 $ 75.1 $ 55.3 Add: Depreciation and amortization expense $ 18.1 $ 17.0 $ 57.3 $ 47.0 Interest expense, net 11.5 12.4 35.7 34.4 (Gain) loss on extinguishment of debt (1.0 ) — (24.9 ) 9.4 Income tax expense (benefit), net 0.4 0.5 1.4 (2.4 ) Contingent consideration adjustments (2) (4.6 ) — (8.3 ) — Non-cash reversal of acquired contractual obligation (3) (0.7 ) — (0.7 ) — Adjusted EBITDA $ 45.7 $ 50.7 $ 135.6 $ 143.7 Subtract: Adjusted EBITDA attributable to Previous Owner (4) $ — $ — $ — $ 1.5 Adjusted EBITDA attributable to noncontrolling interest (5) 0.9 1.9 2.6 7.5 Adjusted EBITDA attributable to SunCoke Energy Partners, L.P. $ 44.8 $ 48.8 $ 133.0 $ 134.7 (1) Beginning in the second quarter of 2016, in response to the SEC’s May 2016 update to its guidance on the appropriate use of non-GAAP financial measures, Adjusted EBITDA no longer includes Coal Logistics deferred revenue until it is recognized as GAAP revenue. (2) The Partnership amended the contingent consideration terms with The Cline Group during the first quarter of 2016. These amendments and subsequent fair value adjustments resulted in gains of $4.6 million and $8.3 million recorded during the three and nine months ended September 30, 2016, respectively, which were excluded from Adjusted EBITDA. (3) In association with the acquisition of CMT, we assumed certain performance obligations under existing contracts and recorded liabilities related to such obligations. In third quarter of 2016, the final acquired contractual performance obligation expired without the customer requiring performance. As such, the Partnership reversed the liability in the period as we no longer have any obligations under the contract.
