Nature of Operations	'
	1. Nature of Operations
	Sprague Resources LP (the “Partnership”) is a Delaware limited partnership formed on June 23, 2011 to engage in the purchase, storage, distribution and sale of refined products and natural gas, and to provide storage and handling services for a broad range of materials.
	Unless the context otherwise requires, references to “Sprague Resources,” and the “Partnership,” when used in a historical context prior to October 30, 2013, the completion date of the initial public offering of the Partnership’s common units (the “IPO”), refer to Sprague Operating Resources LLC, the “Predecessor” for accounting purposes and the successor to Sprague Energy Corp., also referenced as the “Predecessor” and when used in the present tense or prospectively, refer to Sprague Resources LP and its subsidiaries, including Sprague Operating Resources LLC (“OLLC”). Unless the context otherwise requires, references to “Axel Johnson” or the “Parent” refer to Axel Johnson Inc. and its controlled affiliates, collectively, other than Sprague Resources, its subsidiaries and its general partner. References to “Sprague Holdings” refer to Sprague Resources Holdings LLC, a wholly owned subsidiary of Axel Johnson and the owner of the General Partner. References to the “General Partner” refer to Sprague Resources GP LLC.
	Company Businesses
	The Partnership is one of the largest independent wholesale distributors of refined products in the Northeast United States based on aggregate terminal capacity. The Partnership owns, operates, and/or controls a network of 16 refined products and materials handling terminals located in the Northeast United States. The Partnership also utilizes third-party terminals in the Northeast through which it sells or distributes refined products pursuant to rack, exchange and throughput agreements. The Partnership has four business segments: refined products, natural gas, materials handling and other operations. The refined products segment purchases a variety of refined products, such as heating oil, diesel, residual fuel oil, kerosene, jet fuel and gasoline (primarily from refining companies, trading organizations and producers), and sells them to wholesale, commercial, and industrial customers. The natural gas segment purchases, sells and distributes natural gas to commercial and industrial customers in the Northeast and Mid-Atlantic. The Partnership purchases the natural gas it sells from natural gas producers and trading companies. The materials handling segment offloads, stores and prepares for delivery a variety of customer-owned products, including asphalt, clay slurry, salt, gypsum, coal, petroleum coke, caustic soda, tallow, pulp and heavy equipment. The Partnership’s other operations primarily includes the purchase and distribution of coal.
	Since 2007 and through September 30, 2012, the Predecessor, through its wholly-owned foreign subsidiary, Sprague Energy Canada Ltd., owned a 50% equity investment in 9047-1137 Quebec Inc. (“Kildair”), whose primary business is the distribution of residual fuel oil and asphalt. Kildair was not part of the Partnership following the completion of the IPO and, accordingly, Kildair’s results of operations are not included in the results of the Partnership’s operations as discussed below.
	In connection with the completion of the IPO, the Parent contributed to Sprague Holdings all of the ownership interests in the Predecessor. The Predecessor distributed to a wholly owned subsidiary of Sprague Holdings certain assets and liabilities, including among others, the equity investment in Kildair and accounts receivable and cash in an aggregate amount equal to the net proceeds of the IPO. Sprague Holdings then contributed all of the ownership interests in the Predecessor to the Partnership. All of the assets and liabilities of the Predecessor contributed to the Partnership by Sprague Holdings were recorded at the Parent’s historical cost, as the foregoing transactions are among entities under common control. See Note 2—Initial Public Offering. Kildair is not included in the Partnership’s consolidated financial statements effective October 30, 2013, the IPO date, at which time Kildair was distributed to an affiliate of the Parent.
	Basis of Presentation
	The consolidated financial statements included herein reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the Partnership’s consolidated financial position at June 30, 2014 and December 31, 2013 and the consolidated results of operations and cash flows for the three and six months ended June 30, 2014 and 2013, respectively. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year.
	The consolidated financial statements include the accounts of the Partnership and its wholly-owned subsidiaries. Intercompany transactions between the Partnership, the Predecessor and its wholly-owned subsidiaries have been eliminated. Investments in affiliated companies, in which the Partnership or Predecessor own greater than 20% of the voting interest or investees where the Partnership or Predecessor exerts significant influence over such investee but lacks control over the investee are accounted for using the equity method.
	The consolidated financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim financial information. As permitted under those rules, certain notes or other financial information that are normally required by U.S. generally accepted accounting principles (“GAAP”) to be included in annual financial statements have been condensed or omitted from these interim financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and related notes of the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the SEC on March 27, 2014 (the “2013 Annual Report”).
	The significant accounting policies are described in Note 1 “Description of Business and Summary of Significant Accounting Policies” in the Partnership’s audited consolidated financial statement, included in the 2013 Annual Report, and are the same as are used in preparing these unaudited interim consolidated financial statements.
	Demand for some of the Partnership’s refined petroleum products, specifically heating oil and residual oil for space heating purposes, and to a lesser extent natural gas, are generally higher during the first and fourth quarters of the calendar year which may result in significant fluctuations in the Partnership’s quarterly operating results.
	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the balance sheet and the reported revenues and expenses in the income statement. Actual results could differ from those estimates. Among the estimates made by management are asset valuations, the fair value of derivative assets and liabilities, environmental, and legal obligations.
	New Accounting Guidance
	In May 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers, which revises the principles of revenue recognition from one based on the transfer of risks and rewards to when a customer obtains control of a good or service. The Partnership is currently evaluating the potential impact of this guidance which is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted.
	In April 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU revises the criteria for reporting discontinued operations and requires additional disclosures, both for discontinued operations and for individually significant dispositions and assets classified as held for sale not qualifying as discontinued operations. The Partnership has early adopted this guidance on a prospective basis. The adoption did not have a material impact on the Partnership’s consolidated interim financial statements.

Initial Public Offering	'
	2. Initial Public Offering
	On October 30, 2013, in connection with the closing of the IPO, the Partnership sold to the public 8,500,000 of its common units, representing a 42% limited partner interest in the Partnership, at an initial public offering price of $18.00 per unit. Net proceeds of the sale of the common units were $140.3 million after deducting underwriting discounts and commissions, the structuring fee and offering expenses. As of June 30, 2014, the Parent, through its ownership of Sprague Holdings owns 1,571,970 common units and 10,071,970 subordinated units, representing an aggregate 58% limited partner interest in the Partnership. Sprague Holdings also owns the Partnership’s General Partner, which in turn owns a non-economic interest in the Partnership. The principal difference between the Partnership’s common units and subordinated units is that during the subordination period, the common units have the right to receive distributions of cash from distributable cash flow each quarter in an amount equal to $0.4125 per common unit, which is the amount defined in the partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of cash from distributable cash flow may be made on the subordinated units. Furthermore, no arrearages will accrue or be paid on the subordinated units. Upon expiration of the subordination period, any outstanding arrearages in payment of the minimum quarterly distribution on the common units will be extinguished (not paid), each outstanding subordinated unit will immediately convert into one common unit and will thereafter participate pro rata with the other common units in distributions.
	Sprague Holdings currently holds incentive distribution rights (“IDR’s”) that entitle it to receive increasing percentages, up to a maximum of 50%, of the cash the Partnership distributes from distributable cash flow. Participation begins once distributions exceed $0.474375 per unit per quarter. The maximum distribution of 50% does not include any distributions that Sprague Holdings may receive on any limited partner units that it owns.

	3. Acquisitions
	Bridgeport Terminal
	On July 31, 2013, the Predecessor purchased an oil terminal in Bridgeport, Connecticut for $20.7 million. This deep water facility includes 13 storage tanks with 1.3 million barrels of storage capacity for gasoline and distillate products with 11 storage tanks and 1.1 million barrels currently in service. The terminal will provide throughput services to third-parties for branded gasoline sales, and is expected to increase the Predecessor’s marketing of refined products, both gasoline and distillate, in the Connecticut market.
	The acquisition was accounted for as a business combination and was financed with a capital contribution of $10.0 million from the Parent and $10.7 million of borrowings under the acquisition line of the Predecessor’s credit facility.
	The following table summarizes the fair values of the assets acquired:
	Property, plant and equipment	$	20,190
	Intangible assets—customer relationships		510
	Net assets acquired	$	20,700
	The Predecessor recognized $0.2 million of acquisition related costs that were recorded as selling, general and administrative expense at the acquisition date.
	Kildair
	In October 2007, the Predecessor purchased a 50% equity interest in Kildair for $38.7 million. The share purchase agreement provided for the Predecessor to acquire the remaining 50% of Kildair in 2012, subject to terms and conditions within the discretion of the Predecessor, for an additional $27.5 million Canadian, plus a potential earn-out payment if EBITDA over the five year period exceeded $55.0 million Canadian.
	On October 1, 2012 (the “acquisition date”), the Predecessor acquired control of Kildair by purchasing the remaining 50% equity interest. From October 1, 2012 and through the date of the IPO on October 30, 2013, the assets, liabilities, and results of operations of Kildair have been consolidated into the Predecessor’s financial statements. Kildair is not part of the Partnership’s net assets following the completion of the IPO.
	The amount of net sales and net loss of Kildair included in the Predecessor’s Consolidated Statements of Operations for the three and six months ended June 30, 2013 are as follows:
		Three Months Ended			Six Months Ended
		June 30, 2013			June 30, 2013

	The Partnership’s revolving credit agreement (the “Credit Agreement”) was entered into on October 30, 2013 and has a maturity date of October 30, 2018. The Credit Agreement is secured by substantially all of the Partnership’s assets and includes a $750.0 million working capital facility used to fund working capital and post letters of credit and a $250.0 million acquisition facility. Borrowings under the Credit Agreement bear interest based on LIBOR, plus a specified margin, which is a function of the utilization of the Credit Agreement for the working capital facility and leverage ratio for the acquisition facility.
	As of June 30, 2014 and December 31, 2013, working capital facility borrowings were $139.8 million and $351.6 million, respectively, and outstanding letters of credit were $27.7 million and $73.4 million, respectively. The working capital facility is subject to borrowing base reporting and as of June 30, 2014 and December 31, 2013, had a borrowing base of $332.0 million and $573.8 million, respectively. As of June 30, 2014, excess availability under the working capital facility was $164.5 million.
	As of June 30, 2014 and December 31, 2013, acquisition line borrowings were $107.9 million for each respective period. As of June 30, 2014, excess availability under the acquisition facility was $142.1 million.
	The weighted average interest rate at June 30, 2014 and December 31, 2013 was 2.9% for both periods. The current portion of amounts outstanding on the Credit Agreement at June 30, 2014 and December 31, 2013 represents the amounts intended to be repaid during the subsequent twelve month period, respectively.
	The Credit Agreement contains certain restrictions and covenants, including among others, the requirement to maintain a minimum level of net working capital, a fixed charge coverage and a debt leverage ratio and limitations on the incurrence of indebtedness. The Credit Agreement limits the Partnership’s ability to make distributions in the event of a default as defined in the Credit Agreement. As of June 30, 2014, the Partnership is in compliance with these financial covenants.

	The General Partner charges the Partnership for the reimbursements of costs of employees and related employee benefits and other overhead costs supporting the Partnership’s operations which amounted to $15.0 and $45.1 million for the three and six months ended June 30, 2014, respectively. Prior to the IPO, these expenses were incurred directly by the Predecessor. Through the General Partner, the Partnership also participates in certain of the Parent’s pension and other post-retirement benefits. Amounts due to the General Partner were $13.6 million and $4.8 million as of June 30, 2014 and December 31, 2013 respectively.
	During the six months ended June 30, 2013, the Predecessor made a cash dividend to the Parent of $22.5 million as permitted by the Predecessor’s credit agreement and received an advance of $10.0 million from the Parent which was reclassified into equity as a capital contribution upon the successful completion of the acquisition of the oil terminal in Bridgeport, Connecticut.
	During the six months ended June 30, 2013, the Parent charged the Predecessor $0.7 million for oversight and monitoring of the Predecessor. Such amounts are included in selling, general and administrative expenses in the Unaudited Consolidated Statement of Operations. Intercompany activities with the Parent are settled monthly and do not bear interest.

	8. Segment Reporting
	The Partnership is a wholesale and commercial distributor engaged in the purchase, storage, distribution and sale of refined products and natural gas, and also provides storage and handling services for a broad range of materials. The Partnership has four reporting operating segments that comprise the structure used by the chief operating decision makers (CEO and COO/CFO) to make key operating decisions and assess performance. These segments are refined products, natural gas, materials handling and other activities. Segment information includes Kildair since the acquisition date of October 1, 2012 through October 30, 2013, the date Kildair was contributed to an affiliate of Sprague Holdings in connection with the IPO.
	The Partnership’s refined products segment purchases a variety of refined products, such as heating oil, diesel fuel, residual fuel oil, asphalt, kerosene, jet fuel, gasoline and biofuels (primarily from refining companies, trading organizations and producers), and sells them to its customers. The Partnership has wholesale customers who resell the refined products they purchase from the Partnership and commercial customers who consume the refined products they purchase from the Partnership. The Partnership’s wholesale customers consist of home heating oil retailers and diesel fuel and gasoline resellers. The Partnership’s commercial customers include federal and state agencies, municipalities, regional transit authorities, large industrial companies, hospitals and educational institutions.
	The Partnership’s natural gas segment purchases, sells and distributes natural gas to commercial and industrial customers in the Northeast and Mid-Atlantic states. The Partnership purchases natural gas from natural gas producers and trading companies.
	The Partnership’s materials handling segment offloads, stores, and/or prepares for delivery a variety of customer-owned products, including asphalt, clay slurry, salt, gypsum, coal, petroleum coke, caustic soda, tallow, pulp and heavy equipment. These services are fee-based activities which are generally conducted under multi-year agreements.
	The Partnership’s other activities include the purchase, sale and distribution of coal and commercial trucking activities unrelated to its refined products segment. Other activities are not reported separately as they represent less than 10% of consolidated net sales and adjusted gross margin.
	The Partnership evaluates segment performance based on adjusted gross margin, which is gross margin decreased by total commodity derivative gains and losses included in net income (loss) and increased by realized commodity derivative gains and losses included in net income (loss), before allocations of corporate, terminal and trucking operating costs, depreciation, amortization, and interest. Based on the way the business is managed, it is not reasonably possible for the Partnership to allocate the components of operating costs and expenses among the operating segments. There were no significant intersegment sales for any of the periods presented below.
	Summarized financial information for the Partnership’s reportable segments for the three and six months ended June 30, 2014 and 2013 is presented in the table below:

	The Partnership had no single customer whose revenue was greater than 10% of total net sales for the three and six months ended June 30, 2014 and 2013, respectively. The Partnership’s foreign sales, primarily sales of refined products, asphalt and natural gas to its customers in Canada, were $1.1 million and $57.3 million for the three months ended June 30, 2014 and 2013, and $2.1 million and $127.5 million for the six months ended June 30, 2014 and 2013, respectively.
	Segment Assets
	Due to the comingled nature and uses of the Partnership’s fixed assets, the Partnership does not track its fixed assets between its refined products and materials handling operating segments or its other activities. There are no significant fixed assets attributable to the natural gas reportable segment.
	As of June 30, 2014 and December 31, 2013, goodwill for the refined products, natural gas, and materials handling segments amounted to $28.2 million, $4.4 million, and $4.8 million, respectively.

Commodity Derivatives
The Partnership utilizes derivative instruments consisting of futures contracts, forward contracts, swaps, options and other derivatives individually or in combination, to mitigate its exposure to fluctuations in prices of refined petroleum products and natural gas. On a limited basis and within the Partnership’s risk management guidelines, the Partnership utilizes futures contracts, forward contracts, swaps, options and other derivatives to generate profits from changes in market prices. The Partnership invests in futures and over-the-counter (“OTC”) transactions either on regulated exchanges or in the OTC market. Futures contracts are exchange-traded contractual commitments to either receive or deliver a standard amount or value of a commodity at a specified future date and price, with some futures contracts based on cash settlement rather than a delivery requirement. Futures exchanges typically require investors to provide margin deposits as security. OTC contracts, which may or may not require margin deposits as security, involve parties that have agreed either to exchange cash payments or deliver or receive the underlying commodity at a specified future date and price. The Partnership posts initial margin with futures transaction brokers, along with variation margin, which is paid or received on a daily basis, and is included in other current assets in the Consolidated Balance Sheets. In addition, the Partnership may either pay or receive margin based upon exposure with counterparties. Payments made by the Partnership are included in other current assets, whereas payments received by the Partnership are included in accrued liabilities in the Consolidated Balance Sheets. Substantially all of the Partnership’s commodity derivative contracts outstanding as of June 30, 2014 will settle prior to December 31, 2015.
The Partnership enters into some master netting arrangements to mitigate credit risk with significant counterparties. Master netting arrangements are standardized contracts that govern all specified transactions with the same counterparty and allow the Partnership to terminate all contracts upon occurrence of certain events, such as counterparty’s default. The Partnership has elected not to offset the fair value of its derivatives, even where these arrangements provide the right to do so.
The Partnership’s derivative instruments are recorded at fair value, with changes in fair value recognized in net income (loss) or other comprehensive income (loss) each period as appropriate. The Partnership’s fair value measurements are determined using the market approach and includes non-performance risk and time value of money considerations. Counterparty credit is considered for receivable balances, and the Partnership’s credit is considered for payable balances.
The Partnership determines fair value in accordance with Accounting Standards Codification (“ASC”) 820, “ Fair Value Measurements and Disclosures “ which established a hierarchy for the inputs used to measure the fair value of financial assets and liabilities based on the source of the input, which generally range from quoted prices for identical instruments in a principal trading market (Level 1) to estimates determined using significant unobservable inputs (Level 3). Multiple inputs may be used to measure fair value, however, the level of fair value is based on the lowest significant input level within this fair value hierarchy.
Details on the methods and assumptions used to determine the fair values are as follows:
Fair value measurements based on Level 1 inputs: Measurements that are most observable and are based on quoted prices of identical instruments obtained from the principal markets in which they are traded. Closing prices are both readily available and representative of fair value. Market transactions occur with sufficient frequency and volume to assure liquidity.
Fair value measurements based on Level 2 inputs: Measurements that are derived indirectly from observable inputs or from quoted prices from markets that are less liquid. Measurements based on Level 2 inputs include over-the-counter derivative instruments that are priced on an exchange traded curve, but have contractual terms that are not identical to exchange traded contracts. The Partnership utilizes fair value measurements based on Level 2 inputs for its fixed forward contracts, over-the-counter commodity price swaps and interest rate swaps.
Fair value measurements based on Level 3 inputs: Measurements that are least observable are estimated from significant unobservable inputs determined from sources with little or no market activity for comparable contracts or for positions with longer durations.
The Partnership does not offset fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) against the fair value of derivative instruments executed with the same counterparty under the same master netting arrangement. The Partnership had no right to reclaim, or obligation to return, cash collateral as of June 30, 2014 or December 31, 2013.
The following table presents total realized and unrealized (losses) gains on derivative instruments utilized for commodity risk management purposes for the three and six months ended June 30, 2014 and 2013. Such amounts are included in cost of products sold in the Unaudited Consolidated Statements of Operations:

Interest Rate Derivatives
The Partnership has entered into interest rate swaps to manage its exposure to changes in interest rates on its Credit Agreement. The Partnership’s interest rate swaps hedge actual and forecasted LIBOR borrowings and have been designated as cash flow hedges. Counterparties to the Partnership’s interest rate swaps are large multinational banks and the Partnership does not believe there is a material risk of counterparty non-performance. At June 30, 2014, the Partnership held three interest rate swap agreements with a notional value of $100.0 million that expire at various dates through January 2015.
There was no material ineffectiveness determined for the cash flow hedges for the three and six months ended June 30, 2014 and 2013, respectively. Any ineffectiveness is recorded as interest expense in the Unaudited Consolidated Statements of Operations.
The Partnership records unrealized gains and losses on its interest rate swaps as a component of accumulated other comprehensive income (loss), net of tax, which is reclassified to earnings as interest expense when the payments are made. As of June 30, 2014, the amount of unrealized losses, net of tax, expected to be reclassified to earnings during the following twelve-month period was $1.2 million.
The following table presents the location of the gains and losses on derivative contracts designated as cash flow hedging instruments reported in the Unaudited Consolidated Statements of Comprehensive Income as other comprehensive income (loss) (“OCL”) for the three and six months ended June 30, 2014 and 2013:

	The Partnership is involved in various lawsuits, other proceedings and environmental matters, all of which arose in the normal course of business. The Partnership believes, based upon its examination of currently available information, its experience to date, and advice from legal counsel, that the individual and aggregate liabilities resulting from the ultimate resolution of these contingent matters will not have a material adverse impact on the Partnership’s consolidated results of operations, financial position or cash flows. The Partnership maintains insurance coverage and deductibles that it believes are reasonable and prudent.

	11. Equity-Based Compensation
	During the fiscal year ended December 31, 2013, the board of directors of the General Partner issued a total of 6,666 restricted unit awards to certain directors under the Sprague Resources 2013 Long-Term Incentive Plan (the “2013 LTIP”). Recipients have both voting rights and distribution rights on any unvested units. Distributions, if any, shall be paid to the holder of the restricted unit at the same time such distribution is paid to unitholders. The fair value of each restricted unit on the grant date is equal to the market price of the Partnership’s common unit on that date. The estimated fair value of the restricted units is amortized over the vesting period using the straight-line method. Total unrecognized compensation cost related to the nonvested restricted units totaled $0.1 million as of June 30, 2014, which is expected to be recognized over a period of approximately 28 months. The fair value of nonvested restricted units outstanding was approximately $0.2 million as of June 30, 2014.
	On March 31, 2014, the board of directors of the General Partner granted 49,871 awards under the 2013 LTIP to certain directors and employees of the Partnership. Of these total awards, 26,186 (estimated grant date fair value of $0.5 million) were granted to directors and employees as vested common units. In connection with these vested awards, the Partnership reacquired from the recipients 6,768 units (estimated fair value of $0.1 million) to satisfy minimum tax withholding obligations. The remaining 23,685 awards (estimated grant date fair value of $0.5 million), consisted of phantom units issued to employees that are expected to vest as follows: 13,766 units on March 30, 2015 and 9,919 on March 30, 2016. Total unrecognized compensation related to phantom units was $0.4 million as of June 30, 2014 which is expected to be recognized on a straight-line basis over the vesting period. Recipients have distribution rights on any unvested phantom units, which distributions, if any, shall be paid to the holder of the phantom unit at the same time such distribution is paid to unitholders generally. The fair value of phantom units outstanding was approximately $0.6 million as of June 30, 2014.
	A summary of the Partnership’s restricted unit award and phantom unit award activity for the six months ended June 30, 2014, is set forth below:

Earnings Per Unit Calculation	'
	12. Earnings Per Unit Calculation
	Earnings per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income (loss), after deducting any incentive distributions, by the weighted-average number of outstanding common and subordinated units. The Partnership’s net income (loss) is allocated to the limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to Sprague Holdings, the holder of the IDRs, pursuant to the partnership agreement, which are declared and paid following the close of each quarter. Earnings (losses) per unit is only calculated for the Partnership after the IPO as if no units were outstanding prior to October 30, 2013. Earnings in excess of distributions are allocated to the limited partners based on their respective ownership interests. Payments made to the Partnership’s unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of earnings per unit.
	In addition to the common and subordinated units, the Partnership has also identified the IDRs and unvested restricted units as participating securities and uses the two-class method when calculating the net income (loss) per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Diluted earnings per unit includes the effects of potentially dilutive units on the Partnership’s common units, consisting of unvested restricted and phantom units. Basic and diluted earnings per unit applicable to common limited partners are the same in instances where including the effect of unvested restricted and phantom units would be anti-dilutive. Basic and diluted earnings (losses) per unit applicable to subordinated limited partners are the same because there are no potentially dilutive subordinated units outstanding.
	The table below shows the weighted average common units outstanding used to compute net income per common unit for the three and six months ended June 30, 2014.
		Three Months Ended			Six Months Ended

Partnership Distributions	'
	13. Partnership Distributions
	The Partnership agreement sets forth the calculation to be used to determine the amount and priority of cash distributions that the common and subordinated unitholders will receive.
	On January 29, 2014, the Partnership declared a cash distribution totaling $5.7 million, or $0.2825 per unit with respect to the quarter ended December 31, 2013. Such cash distribution was calculated as the minimum quarterly cash distribution of $0.4125 per unit prorated for the period beginning October 30, 2013, the IPO closing date through December 31, 2013. Such distribution was paid on February 14, 2014 to unitholders of record on February 10, 2014.
	On April 29, 2014, the Partnership declared a cash distribution totaling $8.3 million, or $0.4125 per unit for the three months ended March 31, 2014. Such distribution was paid on May 15, 2014, to unitholders of record on May 9, 2014.

	Partnership Distribution
	On July 29, 2014 the Partnership declared a cash distribution totaling $8.6 million, or $0.4275 per unit for the three months ended June 30, 2014. Such distribution will be paid on August 14, 2014, to unitholders of record on August 8, 2014.
	Incentive Compensation Plans
	In previous years the Partnership provided incentive compensation under a program that incorporated an annual bonus paid in cash for substantially all employees and a long term incentive program which was applicable to certain key executives that was also settled in cash. On July 11, 2014, the Board of Directors of the General Partner finalized and approved the 2014 Incentive Compensation Programs under the 2013 LTIP Plan. Under the 2014 programs, which include the annual discretionary bonus and the 2014 LTIP program, a portion of the annual discretionary bonus and all of the awards of the 2014 LTIP Program will be settled in common units. The Partnership estimates that approximately $3.6 million of the incentive compensation accrued as of June 30, 2014 will be settled in units based upon the provisions of these 2014 Programs.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The consolidated financial statements included herein reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the Partnership’s consolidated financial position at June 30, 2014 and December 31, 2013 and the consolidated results of operations and cash flows for the three and six months ended June 30, 2014 and 2013, respectively. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year.
	The consolidated financial statements include the accounts of the Partnership and its wholly-owned subsidiaries. Intercompany transactions between the Partnership, the Predecessor and its wholly-owned subsidiaries have been eliminated. Investments in affiliated companies, in which the Partnership or Predecessor own greater than 20% of the voting interest or investees where the Partnership or Predecessor exerts significant influence over such investee but lacks control over the investee are accounted for using the equity method.
	The consolidated financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim financial information. As permitted under those rules, certain notes or other financial information that are normally required by U.S. generally accepted accounting principles (“GAAP”) to be included in annual financial statements have been condensed or omitted from these interim financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and related notes of the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the SEC on March 27, 2014 (the “2013 Annual Report”).
	The significant accounting policies are described in Note 1 “Description of Business and Summary of Significant Accounting Policies” in the Partnership’s audited consolidated financial statement, included in the 2013 Annual Report, and are the same as are used in preparing these unaudited interim consolidated financial statements.
	Demand for some of the Partnership’s refined petroleum products, specifically heating oil and residual oil for space heating purposes, and to a lesser extent natural gas, are generally higher during the first and fourth quarters of the calendar year which may result in significant fluctuations in the Partnership’s quarterly operating results.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the balance sheet and the reported revenues and expenses in the income statement. Actual results could differ from those estimates. Among the estimates made by management are asset valuations, the fair value of derivative assets and liabilities, environmental, and legal obligations.
New Accounting Guidance	'
	New Accounting Guidance
	In May 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-09, Revenue from Contracts with Customers, which revises the principles of revenue recognition from one based on the transfer of risks and rewards to when a customer obtains control of a good or service. The Partnership is currently evaluating the potential impact of this guidance which is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted.
	In April 2014, the Financial Accounting Standards Board issued Accounting Standard Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU revises the criteria for reporting discontinued operations and requires additional disclosures, both for discontinued operations and for individually significant dispositions and assets classified as held for sale not qualifying as discontinued operations. The Partnership has early adopted this guidance on a prospective basis. The adoption did not have a material impact on the Partnership’s consolidated interim financial statements.
