	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 manufactures coke used in the blast furnace production of steel. On January 24, 2013, we completed the initial public offering ("IPO") of our common units representing limited partner interests. In connection with the IPO, we acquired from SunCoke Energy, Inc. ("SunCoke"), a 65 percent interest in each of Haverhill Coke Company LLC ("Haverhill") and Middletown Coke Company, LLC ("Middletown") and the cokemaking facilities and related assets held by Haverhill and Middletown. At March 31, 2014, SunCoke owns the remaining 35 percent interest in each of Haverhill and Middletown. SunCoke, through its subsidiary, owns a 55.9 percent partnership interest in us and all of our incentive distribution rights and indirectly owns and controls our general partner, which holds a 2 percent general partner interest in us. During 2013, we expanded our operations into coal handling and blending services through two acquisitions. On August 30, 2013, the Partnership completed its acquisition of Lakeshore Coal Handling Corporation ("Lake Terminal"). Located in East Chicago, Indiana, Lake Terminal provides coal handling and blending services to SunCoke's Indiana Harbor cokemaking operations. On October 1, 2013, the Partnership acquired Kanawha River Terminals ("KRT"). KRT is a leading metallurgical and thermal coal blending and handling terminal service provider with collective capacity to blend and transload 30 million tons of coal annually through its operations in West Virginia and Kentucky.

These unaudited interim combined and consolidated financial statements and notes should be read in conjunction with the audited combined and consolidated financial statement and notes included in our Annual Report on Form 10-K for the year ended December 31, 2013.
	The Combined Financial Statements for periods prior to the IPO are the results of SunCoke Energy Partners' Predecessor (the "Predecessor") and were prepared using SunCoke's historical basis in the assets and liabilities of the Predecessor, and include all revenues, costs, assets and liabilities attributed to the Predecessor after the elimination of all significant intercompany accounts and transactions. The Consolidated Financial Statements for the period after the IPO pertain to the operations of the Partnership.

Initial Public Offering [Abstract]	'
Initial Public Offering	'
	2. Initial Public Offering
	On January 23, 2013, in anticipation of the closing of the IPO, we entered into a contribution agreement with Sun Coal & Coke, a subsidiary of SunCoke, and our general partner (the "Contribution Agreement"). Pursuant to the Contribution Agreement, upon the closing of the IPO on January 24, 2013, Sun Coal & Coke contributed to us an interest in each of Haverhill and Middletown, which resulted in our owning a 65 percent interest in each of Haverhill and Middletown. In exchange, our general partner continued to hold a 2 percent general partner interest in us and we issued to our general partner incentive distribution rights ("IDRs") in us. We also issued to Sun Coal & Coke 2,209,697 common units and 15,709,697 subordinated units. The 35 percent interest in each of Haverhill and Middletown retained by Sun Coal & Coke is recorded as a noncontrolling interest of the Partnership. Net Income attributable to noncontrolling interest was $9.9 million and $8.6 million for the three months ended March 31, 2014 and 2013, respectively.
	In conjunction with the closing of the IPO, we sold 13,500,000 common units, representing a 42.1 percent partnership interest, to the public at an initial public offering price of $19.00 per common unit. Gross proceeds from the offering were approximately $256.5 million and net proceeds were approximately $232.0 million after deducting underwriting discounts and offering expenses of $24.7 million, $6.0 million of which were paid by SunCoke in 2012 and reimbursed by us upon the closing of the IPO. We assumed and repaid $225.0 million of SunCoke's term loan debt and we retained $67.0 million for environmental capital expenditures of Haverhill and Middletown, $12.4 million for sales discounts related to tax credits owed to customers of Haverhill, and $39.6 million to replenish our working capital. We used a portion of the net proceeds from the IPO and the concurrent issuance and sale of senior notes discussed below to make a distribution of $33.1 million to SunCoke to, in effect, reimburse SunCoke for expenditures made during the two-year period prior to the IPO for the expansion and improvement of certain assets, an interest in which SunCoke contributed to us in connection with the IPO pursuant to the Contribution Agreement described above.
	Concurrent with the closing of the IPO, we and SunCoke Energy Partners Finance Corp., a Delaware corporation and a wholly owned subsidiary of ours, as co-issuers, issued $150.0 million aggregate principal amount of 7.375 percent senior notes ("Partnership Notes") due 2020 in a private placement to eligible purchasers. The Partnership Notes are the senior unsecured obligations of the co-issuers and are guaranteed on a senior unsecured basis by each of our existing and certain future subsidiaries other than SunCoke Energy Partners Finance Corp. We received net proceeds of approximately $146.3 million, net of debt issuance costs of $3.7 million, from the offering of the Partnership Notes. We also incurred $2.2 million of debt issuance costs related to entering into a revolving credit facility.
	Omnibus Agreement
	In connection with the closing of the 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 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. SunCoke contributed $67 million in satisfaction of this obligation, at the closing date of the IPO, from the proceeds of the IPO and an additional $7 million from our subsequent equity issuance as described in Note 11. If, prior to the fifth anniversary of the closing of the IPO, a pre-existing environmental matter that was discovered either before or after the closing of the IPO is identified as requiring remediation, SunCoke will indemnify us for up to $50 million of any such remediation costs (we will bear the first $5 million of any such costs).
	Other Indemnification. SunCoke will fully indemnify us with respect to any tax liability arising prior to or in connection with the closing of the IPO. 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, 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. Additionally, we paid all fees in connection with our senior notes offering and our revolving credit facility and have agreed to pay all additional 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.

	Net income attributable to SunCoke Energy Partners, L.P. subsequent to initial public offering		$	13.2			$	11.8

	Net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting the general partner’s 2 percent interest and incentive distributions, by the weighted-average number of outstanding common and subordinated units. 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. Net income per unit is only calculated for the Partnership subsequent to the IPO as no units were outstanding prior to January 24, 2013. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. 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. For the three months ended March 31, 2014, the weighted-average number of common and subordinated units outstanding was 15,713,822 units and 15,709,697 units, respectively.
	In addition to the common and subordinated units, we have also identified the general partner interest and incentive distribution rights as participating securities and 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.
	The calculation of net income per unit is as follows:


			Three Months Ended March 31,
			2014				2013
		(Dollars and units in millions, except per unit amounts)
	Net income attributable to SunCoke Energy Partners, L.P. subsequent to initial public offering		$	13.2			$	11.8

	Limited partners' interest in net income subsequent to initial public offering		$	12.8			$	11.6

	Subordinated - SunCoke		$	0.41			$	0.37

	Weighted average limited partner units outstanding:
	Common units - Public		13.5				13.5

	Common units - SunCoke		2.2				2.2

	Subordinated units - SunCoke		15.7				15.7

Cash Distributions
Our partnership agreement generally provides that we will make our distribution, 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

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.
The calculation of net income allocated to the limited partners was as follows:

	At March 31, 2014, the Partnership held $150.0 million Partnership Notes that bear interest at a rate of 7.375 percent per annum and mature on February 1, 2020. Interest on the Partnership Notes is payable semi-annually in cash in arrears on February 1 and August 1 of each year.
	The Partnership also has a revolving credit facility ("Partnership Revolver") with total aggregate commitments from lenders of $150.0 million and also provides for up to $100.0 million uncommitted incremental revolving capacity, subject to the satisfaction of certain conditions. As of March 31, 2014, the Partnership Revolver had $40.0 million borrowing and letters of credit outstanding of $0.7 million, leaving $109.3 million available.
	In connection with the closing of the Partnership offering, we assumed and repaid $225.0 million of SunCoke's term loan. In conjunction with the repayment, we incurred a charge of approximately $2.9 million, which is included in interest expense, net on the Combined and Consolidated Statement of Income, representing the write-off of unamortized debt issuance costs and original issue discount related to the portion of the term loan extinguished. Additionally, with the closing of the Partnership and the issuance of our senior notes, we incurred debt issuance costs of $3.7 million, $0.8 million of which were expensed immediately and were included in interest expense, net during the first quarter of 2013.

	8. Commitments and Contingent Liabilities
	The Environmental Protection Agency ("EPA") and state regulators have issued Notices of Violations (“NOVs”) for the Partnership’s Haverhill cokemaking facility which stem from alleged violations of the air emission operating permits for this facility. The Partnership is working in a cooperative manner with the EPA and the Ohio Environmental Protection Agency ("OEPA") to address the allegations and has lodged a Consent Decree in federal district court that is undergoing review. Settlement may require payment of a civil penalty for alleged past violations as well as the capital projects underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill facility. Any potential penalty for alleged past violations will be paid by SunCoke.
	Spending for these projects depends on the timing and finality of the settlement. We retained $74 million in proceeds from the Partnership offering and our recent equity issuance (See Note 11) for environmental capital expenditures related to these projects. Pursuant to the Omnibus Agreement between SunCoke and the Partnership, any amounts that we spend on these projects in excess of $74 million will be reimbursed by SunCoke. Prior to our formation, SunCoke spent $5 million related to these projects. The Partnership spent $27 million during 2013 and $10 million in the three months ended March 31, 2014. The Partnership expects to spend approximately $28 million in the remainder of 2014 and $10 million in 2015.
	The Partnership is a party to certain other pending and threatened 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 be material in relation to the financial position, results of operations or cash flows of the Partnership.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	9. 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.
	Non-Financial Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). At March 31, 2014, no material fair value adjustments or fair value measurements were required for these non-financial assets or liabilities.
	Certain Financial Assets and Liabilities not Measured at Fair Value
	At March 31, 2014, the estimated fair value of the Partnership's long-term debt was $160.0 million compared to a carrying amount of $149.7 million. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions which are considered Level 3 inputs.

	The Partnership derives its revenues from the Domestic Coke and Coke Logistics reportable segments. Domestic Coke operations are comprised of Haverhill and Middletown cokemaking facilities located in Ohio. Both facilities use similar production processes to produce coke and to recover waste heat that is converted to steam or electricity. Coke sales at each of the Partnership's cokemaking facilities are made pursuant to long-term take-or-pay agreements with ArcelorMittal and AK Steel. Each of the coke sales agreements contain pass-through provisions for costs incurred in the cokemaking process, including coal 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.
	Prior to the third quarter of 2013, Domestic Coke was the Partnership's only reportable segment. The Partnership acquired Lake Terminal on August 30, 2013 and KRT on October 1, 2013 and began providing coal handling and blending services. This business has a collective capacity to blend and transload more than 30 million tons of coal annually. Coal handling and blending services are provided to third party customers as well as SunCoke cokemaking facilities. Coal blending and handling results are presented in the Coal Logistics segment below.
	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 is 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 reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance:

	The Partnership evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation, depletion and amortization (“EBITDA”) adjusted for sales discounts. Prior to the expiration of our nonconventional fuel tax credits in June 2012, EBITDA reflects sales discounts included as a reduction in sales and other operating revenue. The sales discounts represent the sharing with customers of a portion of nonconventional fuel tax credits, which reduce our income tax expense. However, we believe our Adjusted EBITDA would be inappropriately penalized if these discounts were treated as a reduction of EBITDA since they represent sharing of a tax benefit that is not included in EBITDA. Accordingly, in computing Adjusted EBITDA, we have added back these sales discounts. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives 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 of the Partnership's net assets and 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. Adjusted EBITDA is a measure of operating performance that is not defined by GAAP, does not represent and should not be considered a substitute for net income as determined in accordance with GAAP. Calculations of Adjusted EBITDA may not be comparable to those reported by other companies.
	Set forth below is additional detail as to how we use Adjusted EBITDA as a measure of operating performance, as well as a discussion of the limitations of Adjusted EBITDA as an analytical tool.
	Operating Performance. Our management uses Adjusted EBITDA in a number of ways to assess our consolidated financial and operating performance, and we believe this measure is helpful to management in identifying trends in our performance. Adjusted EBITDA helps management identify controllable expenses and make decisions designed to help us meet our current financial goals and optimize our financial performance while neutralizing the impact of capital structure on financial results. Accordingly, we believe this metric measures our financial performance based on operational factors that management can impact in the short-term, namely our cost structure and expenses.
	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 changes in, or cash requirement 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, which is its most directly comparable financial measure calculated and presented in accordance with GAAP:

	11. Subsequent Events
	On April 23, 2014, we executed an agreement to acquire an additional 33 percent interest in the Haverhill and Middletown cokemaking facilities for total consideration of $365.0 million. We expect to close on this agreement in May 2014, subject to customary closing conditions for such transactions and the completion of the associated financing transactions described below. In connection with this agreement we intend to issue, via private placement, approximately $80.0 million of common units and approximately $3.3 million of general partner interests to SunCoke in consideration for the contribution. In addition, we plan to assume and repay approximately $271.3 million of outstanding SunCoke debt and other liabilities and pay approximately $3.4 million in cash to SunCoke. We expect to retain approximately $7.0 million of the consideration to pre-fund SunCoke’s obligation to indemnify us for the anticipated cost of the environmental remediation project at Haverhill. The debt assumption and repayment obligation consists of approximately $99.9 million of SunCoke’s outstanding term loan debt and $171.4 million of SunCoke’s senior unsecured notes, inclusive of an estimated market premium of $11.4 million to tender for the principal amount of these notes.
	We expect to fund the debt assumption and cash portions of the consideration with approximately $88 million of proceeds from the sale of 3.2 million common units to the public, which was completed on April 30, 2014, and approximately $263 million of gross proceeds from the expected issuance of $250 million aggregate principal amount of 7.375 percent senior notes due 2020 through a private placement in May 2014. Proceeds from the offerings will also be used to repay approximately $40 million outstanding on our revolving credit facility, pay transaction fees and for general corporate purposes.
	The terms of the contribution agreement, and the acquisition of the interests in Haverhill and Middletown, have been approved by the conflicts committee of our general partner’s Board of Directors, which consists entirely of independent directors.
