Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Basis of Presentation and Use of Estimates The accompanying unaudited interim Condensed Consolidated Financial Statements (“interim statements”) of the Partnership have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. These interim statements should be read in conjunction with the Partnership’s Consolidated Financial Statements for the year ended December 31, 2014, which are included in the Partnership’s Annual Report on Form 10-K filed with the SEC on February 27, 2015. The year-end balance sheet data was derived from the audited financial statements, but does not include all disclosures required by GAAP. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. Hi-Crush Partners LP (together with its subsidiaries, the “Partnership”, “we”, “us” or “our”) is a Delaware limited partnership formed on May 8, 2012 to acquire selected sand reserves and related processing and transportation facilities of Hi-Crush Proppants LLC. In connection with its formation, the Partnership issued a non-economic general partner interest to Hi-Crush GP LLC, our general partner (the “General Partner” or “Hi-Crush GP”), and a 100.0% limited partner interest to Hi-Crush Proppants LLC (the “sponsor”), its organizational limited partner. On April 8, 2014, the Partnership entered into a contribution agreement with the sponsor to acquire substantially all of the remaining equity interests in the sponsor’s Augusta facility for cash consideration of $224,250 (the “Augusta Contribution”, See Note 5 - Acquisition of Hi-Crush Augusta LLC). To finance the Augusta Contribution and refinance the Partnership’s revolving credit facility, (i) on April 8, 2014, the Partnership commenced a primary public offering of 4,250,000 common units representing limited partnership interests in the Partnership and (ii) on April 28, 2014, the Partnership entered into a $200,000 senior secured term loan facility with certain lenders. The Partnership’s primary public offering closed on April 15, 2014. On May 9, 2014, the Partnership issued an additional 75,000 common units pursuant to the partial exercise of the underwriters' over-allotment option in connection with the April 2014 primary public offering. Net proceeds to the Partnership from the primary offering and the exercise of the over-allotment option totaled $170,693 . Upon receipt of the proceeds from the public offering on April 15, 2014, the Partnership paid off the outstanding balance of $124,750 under its revolving credit facility. The Augusta Contribution closed on April 28, 2014, and at closing, the Partnership’s preferred equity interest in Augusta was converted into common equity interests of Augusta. Following the Augusta Contribution, the Partnership owns 98.0% of Augusta’s common equity interests. In addition, on April 28, 2014, the Partnership entered into a $150,000 senior secured revolving credit facility with various financial institutions by amending and restating its prior $200,000 revolving credit facility (See Note 6 - Long-Term Debt). The Augusta Contribution was accounted for as a transaction between entities under common control whereby Augusta's net assets were recorded at their historical cost. Therefore, the Partnership's historical financial information was recast to combine Augusta and the Partnership as if the combination had been in effect since inception of common control. Refer to Note 5 for additional disclosure regarding the Augusta Contribution.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies In addition to the significant accounting policies listed below, a comprehensive discussion of our critical accounting policies and estimates is included in our Annual Report on Form 10-K filed with the SEC on February 27, 2015. Restricted Cash The Partnership must pledge cash escrow accounts for the benefit of the Pennsylvania Department of Transportation, Bureau of Rail Freight, Ports and Waterways (“PennDOT”) to guarantee performance on rail improvement projects partially funded by PennDOT. The funds are released when the project is completed. Revenue Recognition Frac sand sales revenues are recognized when legal title passes to the customer, which may occur at the production facility, rail origin or at the destination terminal. At that point, delivery has occurred, evidence of a contractual arrangement exists and collectability is reasonably assured. Amounts received from customers in advance of sand deliveries are recorded as deferred revenue. Revenue from make-whole provisions in our customer contracts is recognized at the end of the defined cure period. A substantial portion of our frac sand is sold to customers with whom we have long-term supply agreements, the current terms of which expire between 2016 and 2020 . The agreements define, among other commitments, the volume of product that the Partnership must provide, the price that will be charged to the customer, and the volume that the customer must purchase by the end of the defined cure periods, which can range from three months to the end of a contract year. Transportation services revenues are recognized as the services have been completed, meaning the related services have been rendered. At that point, delivery of service has occurred, evidence of a contractual arrangement exists and collectability is reasonably assured. Amounts received from customers in advance of transportation services being rendered are recorded as deferred revenue. Revenue attributable to silo storage leases is recorded on a straight-line basis over the term of the lease. Fair Value of Financial Instruments The amounts reported in the balance sheet as current assets or liabilities, including cash, accounts receivable, accounts payable, accrued and other current liabilities approximate fair value due to the short-term maturities of these instruments. The fair value of the senior secured term loan approximated $191,575 as of June 30, 2015 , based on the market price quoted from external sources, compared with a carrying value of $197,500 . If the senior secured term loan was measured at fair value in the financial statements, it would be classified as Level 2 in the fair value hierarchy. Net Income per Limited Partner Unit We have identified the sponsor’s incentive distribution rights as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the partnership agreement. Net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting any sponsor incentive distributions, by the weighted-average number of outstanding common and subordinated units. Through March 31, 2014, basic and diluted net income per unit were the same as there were no potentially dilutive common or subordinated units outstanding. Through August 15, 2014, the 3,750,000 Class B units outstanding did not have voting rights or rights to share in the Partnership’s periodic earnings, either through participation in its distributions or through an allocation of its undistributed earnings or losses, and so were not deemed to be participating securities in their form as Class B units. In addition, the conversion of the Class B units into common units was fully contingent upon the satisfaction of defined criteria pertaining to the cumulative payment of distributions and earnings per unit of the Partnership as described in Note 7. As such, until all of the defined payment and earnings criteria were satisfied, the Class B units were not included in our calculation of either basic or diluted earnings per unit. As such, for the quarter ended June 30, 2014, the Class B units were included in our calculation of diluted earnings per unit. On August 15, 2014, the Class B units converted into common units, at which time income allocations commenced on such units and the common units were included in our calculation of basic and diluted earnings per unit. As described in Note 1, the Partnership's historical financial information has been recast to consolidate Augusta for all periods presented. The amounts of incremental income or losses recasted to periods prior to the Augusta Contribution are excluded from the calculation of net income per limited partner unit. Income Taxes The Partnership is a pass-through entity and is not considered a taxing entity for federal tax purposes. Therefore, there is not a provision for income taxes in the accompanying condensed consolidated financial statements. The Partnership’s net income or loss is allocated to its partners in accordance with the partnership agreement. The partners are taxed individually on their share of the Partnership’s earnings. At June 30, 2015 and December 31, 2014 , the Partnership did not have any liabilities for uncertain tax positions or gross unrecognized tax benefit. Recent Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update No. 2015-06, which specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings (losses) of a transferred business before the date of a drop down transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners (which is typically the earnings per unit measure presented in the financial statements) would not change as a result of the drop down transaction. In addition, the standard requires additional qualitative disclosures about how the rights to the earnings (losses) differ before and after the drop down transaction occurs for purposes of computing earnings per unit under the two-class method. The new accounting guidance is effective for the Partnership beginning in the first quarter of 2016, and should be applied retrospectively. The Partnership is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and footnote disclosures, but does not anticipate that adoption will have a material impact on its financial position, results of operations or cash flows.

Business Combinations [Abstract]
Acquisition of Hi-Crush Augusta LLC	Acquisition of Hi-Crush Augusta LLC On January 31, 2013, the Partnership entered into an agreement with our sponsor to acquire 100,000 preferred units in Hi-Crush Augusta LLC ("Augusta"), the entity that owned our sponsor’s Augusta facility, for $37,500 in cash and 3,750,000 newly issued convertible Class B units in the Partnership. On April 28, 2014, the Partnership acquired 390,000 common units in Augusta for cash consideration of $224,250 . In connection with this acquisition, the Partnership’s preferred equity interest in Augusta was converted into 100,000 common units of Augusta. Following this transaction, the Partnership maintained a 98.0% controlling interest in Augusta’s common units, with our sponsor owning the remaining 2.0% of common units. The Augusta Contribution was accounted for as a transaction between entities under common control whereby Augusta's net assets were recorded at their historical cost. The difference between the consideration paid and the recasted historical cost of the net assets acquired was allocated in accordance with the partnership agreement to the common and subordinated unitholders based on their respective number of units outstanding as of April 28, 2014. However, this deemed distribution did not affect the tax basis capital accounts of the common and subordinated unitholders. The Partnership's historical financial information was recast to combine the Condensed Consolidated Statements of Operations and the Condensed Consolidated Balance Sheets of the Partnership with those of Augusta as if the combination had been in effect since inception of common control. Any material transactions between the Partnership and Augusta have been eliminated. The balance of non-controlling interest as of April 28, 2014 represented the sponsor's interest in Augusta prior to the combination. Except for the combination of Condensed Consolidated Statements of Operations and the respective allocation of recasted net income between the controlling and non-controlling interest, capital transactions between the sponsor and Augusta prior to April 28, 2014 have not been allocated on a recasted basis to the common and subordinated unitholders. Such transactions are presented within the non-controlling interest column in the Condensed Consolidated Statement of Partners' Capital as the Partnership and its unitholders would not have participated in these transactions. The following table summarizes the carrying value of Augusta's assets as of April 28, 2014, and the allocation of the cash consideration paid: Net assets of Hi-Crush Augusta LLC as of April 28, 2014: Cash $ 1,035 Accounts receivable 9,816 Inventories 4,012 Prepaid expenses and other current assets 114 Due from Hi-Crush Partners LP 1,756 Property, plant and equipment 84,900 Accounts payable (3,379 ) Accrued liabilities and other current liabilities (2,926 ) Due to sponsor (4,721 ) Asset retirement obligation (2,993 ) Total carrying value of Augusta's net assets $ 87,614 Allocation of purchase price Carrying value of sponsor's non-controlling interest prior to Augusta Contribution $ 35,951 Less: Carrying value of 2% of non-controlling interest retained by sponsor (1,752 ) Purchase price allocated to non-controlling interest acquired 34,199 Excess purchase price over the historical cost of the acquired non-controlling interest (a) 190,051 Cost of Augusta acquisition $ 224,250 (a) The deemed distribution attributable to the excess purchase price was allocated to the common and subordinated unitholders based on the respective number of units outstanding as of April 28, 2014.

Long-Term Debt	Long-Term Debt Long-term debt consisted of the following: June 30, 2015 December 31, 2014 Term Loan Credit Facility $ 195,830 $ 196,688 Revolving Credit Facility 37,500 — Other notes payable 3,676 3,676 Less: current portion of long-term debt (2,000 ) (2,000 ) Long-term debt $ 235,006 $ 198,364 Revolving Credit Facility On August 21, 2012 , the Partnership entered into a credit agreement (the “Prior Credit Agreement”) providing for a $100,000 senior secured revolving credit facility (the “Prior Credit Facility”) with a term of four years. In connection with our acquisition of a preferred interest in Augusta, on January 31, 2013, the Partnership entered into a consent and first amendment to the Prior Credit Agreement whereby the lending banks, among other things, (i) consented to the amendment and restatement of the partnership agreement of the Partnership and (ii) agreed to amend the Prior Credit Agreement to permit the acquisition by the Partnership of a preferred equity interest in Hi-Crush Augusta LLC. On May 9, 2013, in connection with our acquisition of D & I Silica, LLC ("D&I"), the Partnership entered into a commitment increase agreement and second amendment to the Prior Credit Agreement whereby the lending banks, among other things, consented to the increase of the aggregate commitments by $100,000 to a total of $200,000 and addition of lenders to the lending bank group. The outstanding balance under the Prior Credit Facility was paid in full on April 15, 2014 . On April 28, 2014, the Partnership replaced the Prior Credit Facility by entering into an amended and restated credit agreement (the "Revolving Credit Agreement"). The Revolving Credit Agreement is a senior secured revolving credit facility (the "Revolving Credit Facility") that permits aggregate borrowings of up to $150,000 , including a $25,000 sublimit for letters of credit and a $10,000 sublimit for swing line loans. The Revolving Credit Facility matures on April 28, 2019 . The Revolving Credit Facility is secured by substantially all assets of the Partnership. In addition, the Partnership's subsidiaries have guaranteed the Partnership's obligations under the Revolving Credit Agreement and have granted to the revolving lenders security interests in substantially all of their respective assets. Borrowings under the Revolving Credit Agreement bear interest at a rate equal to, at the Partnership's option, either (1) a base rate plus an applicable margin ranging between 1.25% per annum and 2.50% per annum, based upon the Partnership's leverage ratio, or (2) a Eurodollar rate plus an applicable margin ranging between 2.25% per annum and 3.50% per annum, based upon the Partnership's leverage ratio. The Revolving Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants, including limits or restrictions on the Partnership’s ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and dispose of assets. The Revolving Credit Agreement also requires compliance with customary financial covenants, which are a leverage ratio and minimum interest coverage ratio. In addition, it contains customary events of default that entitle the lenders to cause any or all of the Partnership’s indebtedness under the Revolving Credit Agreement to become immediately due and payable. The events of default (some of which are subject to applicable grace or cure periods), include among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults and material judgment defaults. As of June 30, 2015 , we were in compliance with the covenants contained in the Revolving Credit Agreement. As of June 30, 2015 , we had $104,811 of undrawn borrowing capacity ( $150,000 , net of $37,500 indebtedness and $7,689 letter of credit commitments) under our Revolving Credit Facility. Term Loan Credit Facility On April 28, 2014, the Partnership entered into a credit agreement (the "Term Loan Credit Agreement") providing for a senior secured term loan credit facility (the “Term Loan Credit Facility”) that permits aggregate borrowings of up to $200,000 , which was fully drawn on April 28, 2014. The Term Loan Credit Agreement permits the Partnership, at its option, to add one or more incremental term loan facilities in an aggregate amount not to exceed $100,000 . Any incremental term loan facility would be on terms to be agreed among the Partnership, the administrative agent and the lenders who agree to participate in the incremental facility. The maturity date of the Term Loan Credit Facility is April 28, 2021 . The Term Loan Credit Agreement is secured by substantially all assets of the Partnership. In addition, the Partnership’s subsidiaries have guaranteed the Partnership’s obligations under the Term Loan Credit Agreement and have granted to the lenders security interests in substantially all of their respective assets. Borrowings under the Term Loan Credit Agreement bear interest at a rate equal to, at the Partnership’s option, either (1) a base rate plus an applicable margin of 2.75% per annum or (2) a Eurodollar rate plus an applicable margin of 3.75% per annum, subject to a LIBOR floor of 1.00% . The Term Loan Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants, including limits or restrictions on the Partnership’s ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and dispose of assets. In addition, it contains customary events of default that entitle the lenders to cause any or all of the Partnership’s indebtedness under the Term Loan Credit Agreement to become immediately due and payable. The events of default (some of which are subject to applicable grace or cure periods), include, among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults and material judgment defaults. As of June 30, 2015 , we were in compliance with the terms of the agreement. As of June 30, 2015 , we had $195,830 indebtedness ( $197,500 , net of $1,670 of discounts) under our Term Loan Credit Facility, which carried an interest rate of 4.75% as of June 30, 2015 . Other Notes Payable On October 24, 2014, the Partnership acquired land and underlying frac sand deposits. The Partnership paid cash consideration of $2,500 , and issued a three -year promissory note in the amount of $3,676 . The three year promissory note accrues interest at a rate equal to the applicable short-term federal rate, which was 0.43% as of June 30, 2015. All principal and accrued interest is due and payable at the end of the three-year note term. However, the note may be prepaid on a quarterly basis during the three-year term if sand is extracted, delivered, sold and paid for from the property. The Partnership did not make any prepayments during the six months ended June 30, 2015.

Equity [Abstract]
Equity	Equity As of June 30, 2015 , our sponsor owned 13,640,351 subordinated units representing a 36.9% ownership interest in the limited partner units. In addition, our sponsor is the owner of our General Partner. Class B Units On January 31, 2013, the Partnership issued 3,750,000 subordinated Class B units and paid $37,500 in cash to our sponsor in return for 100,000 preferred equity units in our sponsor’s Augusta facility. The Class B units did not have voting rights or rights to share in the Partnership’s periodic earnings, either through participation in its distributions or through an allocation of its undistributed earnings or losses. The Class B units were eligible for conversion into common units upon satisfaction of certain conditions. The conditions precedent to conversion of the Class B units were satisfied upon payment of our distribution on August 15, 2014 and, upon such payment, our sponsor, who was the sole owner of our Class B units, elected to convert all of the 3,750,000 Class B units into common units on a one-for-one basis. Incentive Distribution Rights Incentive distribution rights represent the right to receive increasing percentages (ranging from 15.0% to 50.0% ) of quarterly distributions from operating surplus after minimum quarterly distribution and target distribution levels exceed $0.54625 per unit per quarter. Our sponsor currently holds the incentive distribution rights, but it may transfer these rights at any time. Allocations of Net Income Our partnership agreement contains provisions for the allocation of net income and loss to the unitholders and our 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 ownership 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% to our sponsor. During the three and six months ended June 30, 2014, no net income was allocated to our Class B units or to holders of incentive distribution rights. During the three months ended June 30, 2015, no distributions were allocated to our holders of incentive distribution rights. During the six months ended June 30, 2015, $1,311 was allocated to our holders of incentive distribution rights. Distributions Our partnership agreement sets forth the calculation to be used to determine the amount of cash distributions that our common and subordinated unitholders and our sponsor will receive. Our recent distributions have been as follows: Declaration Date Amount Declared Per Unit Record Date Payment Date Payment to Common and Subordinated Units Payment to Holders of Incentive Distribution Rights January 15, 2014 $ 0.5100 January 31, 2014 February 14, 2014 $ 14,726 $ — April 16, 2014 $ 0.5250 May 1, 2014 May 15, 2014 $ 17,388 $ — July 16, 2014 $ 0.5750 August 1, 2014 August 15, 2014 $ 19,088 $ 168 October 15, 2014 $ 0.6250 October 31, 2014 November 14, 2014 $ 23,092 $ 695 January 15, 2015 $ 0.6750 January 30, 2015 February 13, 2015 $ 24,947 $ 1,311 April 16, 2015 $ 0.6750 May 1, 2015 May 15, 2015 $ 24,947 $ 1,311 July 21, 2015 $ 0.4750 August 5, 2015 August 14, 2015 $ 17,555 $ — Net Income per Limited Partner Unit The following table outlines our basic and diluted, weighted average limited partner units outstanding during the relevant periods: Three Months Ended Six Months Ended June 30, June 30, Weighted average limited partner units outstanding: 2015 2014 2015 2014 Common units - basic 23,318,419 18,828,359 23,318,174 17,040,874 Subordinated units - basic 13,640,351 13,640,351 13,640,351 13,640,351 Common units - diluted 23,560,423 22,721,490 23,560,178 20,934,005 Subordinated units - diluted 13,640,351 13,640,351 13,640,351 13,640,351 For purposes of calculating the Partnership’s earnings per unit under the two-class method, common units are treated as participating preferred units, and subordinated units are treated as the residual equity interest, or common equity. Incentive distribution rights are treated as participating securities. As the Class B units did not have rights to share in the Partnership’s periodic earnings, whether through participation in its distributions or through an allocation of its undistributed earnings or losses, they were not participating securities. In addition, the conversion of the Class B units into common units was fully contingent upon the satisfaction of defined criteria. As such, until all of the defined payment and earnings criteria were satisfied, the Class B units were not included in our calculation of either basic or diluted earnings per unit during the three months ended March 31, 2014. The Class B units were converted into common units on August 15, 2014, at which time income allocations commenced on such units. Diluted earnings per unit for the three and six months ended June 30, 2015 includes the dilutive effect of LTIP awards granted (see Note 8) at the assumed number of units which would have vested if the performance period had ended on June 30, 2015. Distributions made in future periods based on the current period calculation of cash available for distribution are allocated to each class of equity that will receive such distributions. Any unpaid cumulative distributions are allocated to the appropriate class of equity. Each period the Partnership determines the amount of cash available for distributions in accordance with the partnership agreement. The amount to be distributed to common unitholders, subordinated unitholders and incentive distribution rights holders is based on the distribution waterfall in the partnership agreement. Net earnings for the period are allocated to each class of partnership interest based on the distributions to be made. Additionally, if, during the subordination period, the Partnership does not have enough cash available to make the required minimum distribution to the common unit holders, the Partnership will allocate net earnings to the common unit holders based on the amount of distributions in arrears. When actual cash distributions are made based on distributions in arrears, those cash distributions will not be allocated to the common unitholders, as such earnings were allocated in previous periods. The following table provides a reconciliation of net income and the assumed allocation of net income under the two-class method for purposes of computing net income per unit for the three months ended June 30, 2015 (in thousands, except per unit amounts): General Partner and IDRs Common Units Subordinated Units Total Declared distribution $ — $ 11,076 $ 6,479 $ 17,555 Assumed allocation of distributions in excess of earnings — (3,852 ) (2,253 ) (6,105 ) Limited partners’ interest in net income $ — $ 7,224 $ 4,226 $ 11,450 Earnings per unit - basic $ 0.31 $ 0.31 Earnings per unit - diluted $ 0.31 $ 0.31 The following table provides a reconciliation of net income and the assumed allocation of net income under the two-class method for purposes of computing net income per unit for the six months ended June 30, 2015 (in thousands, except per unit amounts): General Partner and IDRs Common Units Subordinated Units Total Declared distribution $ 1,311 $ 26,816 $ 15,686 $ 43,813 Assumed allocation of distributions in excess of earnings — (5,475 ) (3,203 ) (8,678 ) Limited partners’ interest in net income $ 1,311 $ 21,341 $ 12,483 $ 35,135 Earnings per unit - basic $ 0.92 $ 0.92 Earnings per unit - diluted $ 0.91 $ 0.91 Recasted Augusta Equity Transactions During the six months ended June 30, 2014, the sponsor provided $492 of management services and other expenses paid on behalf of Augusta.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Unit Based Compensation	Unit-Based Compensation Long-Term Incentive Plan On August 21, 2012, Hi-Crush GP adopted the Hi-Crush Partners LP Long Term Incentive Plan (the “Plan”) for employees, consultants and directors of Hi-Crush GP and those of its affiliates, including our sponsor, who perform services for the Partnership. The Plan consists of restricted units, unit options, phantom units, unit payments, unit appreciation rights, other equity-based awards, distribution equivalent rights and performance awards. The Plan limits the number of common units that may be issued pursuant to awards under the Plan to 1,364,035 units. Common units withheld to satisfy exercise prices or tax withholding obligations are available for delivery pursuant to other awards. The Plan is administered by Hi-Crush GP’s Board of Directors or a committee thereof. The cost of services received in exchange for an award of equity instruments is measured based on the grant-date fair value of the award and that cost is generally recognized over the vesting period of the award. Performance Phantom Units - Equity Settled The Partnership has awarded Performance Phantom Units ("PPUs") pursuant to the Plan to certain employees. The number of PPUs that will vest will range from 0% to 200% of the number of initially granted PPUs and is dependent on the Partnership's total unitholder return over a three -year performance period compared to the total unitholder return of a designated peer group. Each PPU represents the right to receive, upon vesting, one common unit representing limited partner interests in the Partnership. The PPUs are also entitled to forfeitable distribution equivalent rights ("DERs"), which accumulate during the performance period and are paid in cash on the date of settlement. The fair value of each PPU is estimated using a fair value approach and is amortized into compensation expense, reduced for an estimate of expected forfeitures, over the period of service corresponding with the vesting period. Expected volatility is based on the historical market performance of our peer group. The following table presents information relative to our PPUs. Units Grant Date Weighted-Average Fair Value per Unit Outstanding at January 1, 2015 64,414 $ 65.57 Granted 119,550 $ 37.52 Forfeited — $ — Outstanding at June 30, 2015 183,964 $ 47.34 As of June 30, 2015, total compensation expense not yet recognized related to unvested PPUs was $6,297 , with a weighted average remaining service period of 2.2 years. Time-Based Phantom Units - Equity Settled The Partnership has awarded Time-Based Phantom Units ("TPUs") pursuant to the Plan to certain employees which automatically vest if the employee remains employed at the end of a three -year vesting period. Each TPU represents the right to receive, upon vesting, one common unit representing limited partner interests in the Partnership. The TPUs are also entitled to forfeitable DERs, which accumulate during the vesting period and are paid in cash on the date of settlement. The fair value of each TPU is calculated based on the grant-date unit price and is amortized into compensation expense, reduced for an estimate of expected forfeitures, over the period of service corresponding with the vesting period. The following table presents information relative to our TPUs. Units Grant Date Weighted-Average Fair Value per Unit Outstanding at January 1, 2015 16,603 $ 47.33 Granted 42,200 $ 34.09 Forfeited (763 ) $ 59.00 Outstanding at June 30, 2015 58,040 $ 37.55 As of June 30, 2015, total compensation expense not yet recognized related to unvested TPUs was $1,755 , with a weighted average remaining service period of 2.4 years. Board and Other Unit Grants The Partnership issued 6,344 and 5,532 common units to its independent directors during the six months ended June 30, 2015 and 2014, respectively. During the six months ended June 30, 2014, the Partnership issued 7,022 common units to certain employees which vest approximately over a two year period.

Significant Accounting Polici20

Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2015
Accounting Policies [Abstract]
Restricted Cash	Restricted Cash The Partnership must pledge cash escrow accounts for the benefit of the Pennsylvania Department of Transportation, Bureau of Rail Freight, Ports and Waterways (“PennDOT”) to guarantee performance on rail improvement projects partially funded by PennDOT. The funds are released when the project is completed.
Revenue Recognition	Revenue Recognition Frac sand sales revenues are recognized when legal title passes to the customer, which may occur at the production facility, rail origin or at the destination terminal. At that point, delivery has occurred, evidence of a contractual arrangement exists and collectability is reasonably assured. Amounts received from customers in advance of sand deliveries are recorded as deferred revenue. Revenue from make-whole provisions in our customer contracts is recognized at the end of the defined cure period. A substantial portion of our frac sand is sold to customers with whom we have long-term supply agreements, the current terms of which expire between 2016 and 2020 . The agreements define, among other commitments, the volume of product that the Partnership must provide, the price that will be charged to the customer, and the volume that the customer must purchase by the end of the defined cure periods, which can range from three months to the end of a contract year. Transportation services revenues are recognized as the services have been completed, meaning the related services have been rendered. At that point, delivery of service has occurred, evidence of a contractual arrangement exists and collectability is reasonably assured. Amounts received from customers in advance of transportation services being rendered are recorded as deferred revenue. Revenue attributable to silo storage leases is recorded on a straight-line basis over the term of the lease.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The amounts reported in the balance sheet as current assets or liabilities, including cash, accounts receivable, accounts payable, accrued and other current liabilities approximate fair value due to the short-term maturities of these instruments. The fair value of the senior secured term loan approximated $191,575 as of June 30, 2015 , based on the market price quoted from external sources, compared with a carrying value of $197,500 . If the senior secured term loan was measured at fair value in the financial statements, it would be classified as Level 2 in the fair value hierarchy.
Net Income per Limited Partner Unit	Net Income per Limited Partner Unit We have identified the sponsor’s incentive distribution rights as participating securities and compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the partnership agreement. Net income per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income, after deducting any sponsor incentive distributions, by the weighted-average number of outstanding common and subordinated units. Through March 31, 2014, basic and diluted net income per unit were the same as there were no potentially dilutive common or subordinated units outstanding. Through August 15, 2014, the 3,750,000 Class B units outstanding did not have voting rights or rights to share in the Partnership’s periodic earnings, either through participation in its distributions or through an allocation of its undistributed earnings or losses, and so were not deemed to be participating securities in their form as Class B units. In addition, the conversion of the Class B units into common units was fully contingent upon the satisfaction of defined criteria pertaining to the cumulative payment of distributions and earnings per unit of the Partnership as described in Note 7. As such, until all of the defined payment and earnings criteria were satisfied, the Class B units were not included in our calculation of either basic or diluted earnings per unit. As such, for the quarter ended June 30, 2014, the Class B units were included in our calculation of diluted earnings per unit. On August 15, 2014, the Class B units converted into common units, at which time income allocations commenced on such units and the common units were included in our calculation of basic and diluted earnings per unit. As described in Note 1, the Partnership's historical financial information has been recast to consolidate Augusta for all periods presented. The amounts of incremental income or losses recasted to periods prior to the Augusta Contribution are excluded from the calculation of net income per limited partner unit.
Income Taxes	Income Taxes The Partnership is a pass-through entity and is not considered a taxing entity for federal tax purposes. Therefore, there is not a provision for income taxes in the accompanying condensed consolidated financial statements. The Partnership’s net income or loss is allocated to its partners in accordance with the partnership agreement. The partners are taxed individually on their share of the Partnership’s earnings. At June 30, 2015 and December 31, 2014 , the Partnership did not have any liabilities for uncertain tax positions or gross unrecognized tax benefit.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update No. 2015-06, which specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings (losses) of a transferred business before the date of a drop down transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners (which is typically the earnings per unit measure presented in the financial statements) would not change as a result of the drop down transaction. In addition, the standard requires additional qualitative disclosures about how the rights to the earnings (losses) differ before and after the drop down transaction occurs for purposes of computing earnings per unit under the two-class method. The new accounting guidance is effective for the Partnership beginning in the first quarter of 2016, and should be applied retrospectively. The Partnership is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and footnote disclosures, but does not anticipate that adoption will have a material impact on its financial position, results of operations or cash flows.
