Debt Disclosure [Abstract]
Credit Facility	(9) Credit Facility The Partnership's credit facility includes a term loan facility of $125.0 million and a revolving credit facility of $25.0 million with an uncommitted incremental facility of up to $50.0 million. No amounts were outstanding under the revolving credit facility at December 31, 2015 or 2014. There is no scheduled amortization. The credit facility matures on April 13, 2016. The principal portion of the term loan is presented as long-term debt on the Consolidated Balance Sheet as of December 31, 2015 as the Partnership has the intent and ability to refinance the obligation on a long-term basis, as discussed below. The Partnership is considering capital structure and refinancing options associated with the credit facility maturity. Borrowings under the credit facility bear interest at either a Eurodollar rate or a base rate plus a margin based on a pricing grid determined by the trailing four quarter leverage ratio. The margin for borrowings under the credit facility ranges from 3.50% to 4.25% for Eurodollar loans and 2.50% to 3.25% for base rate loans. Currently, the interest rate is either the Eurodollar rate plus a margin of 3.50% or, for base rate loans, the prime rate plus 2.50%. Under its terms, the lenders under the credit facility were granted a first priority security interest (subject to certain customary exceptions) in substantially all of the assets of CVR Partners and CRNF. At December 31, 2015, the effective rate was approximately 4.60%, inclusive of the impact of the interest rate swaps discussed in Note 10 ("Interest Rate Swap Agreements"). The credit facility requires CVR Partners to maintain a minimum interest coverage ratio and a maximum leverage ratio and contains customary covenants for a financing of this type that limit, subject to certain exceptions, the incurrence of additional indebtedness or guarantees, creation of liens on assets, and the ability to dispose assets, make restricted payments, investments or acquisitions, enter into sale-leaseback transactions or enter into affiliate transactions. The credit facility provides that the Partnership can make distributions to holders of the Partnership's common units provided the Partnership is in compliance with its leverage ratio and interest coverage ratio covenants on a pro forma basis after giving effect to such distribution and there is no default or event of default under the facility. As of December 31, 2015, CRNF was in compliance with the covenants contained in the credit facility. The Partnership is required to prepay outstanding amounts under the term facility in an amount equal to the net proceeds from the sale of assets or from insurance or condemnation awards related to collateral, in each case subject to certain reinvestment rights. In addition, the Partnership is required to prepay outstanding amounts under the term facility with the net proceeds from certain issuances of debt (other than debt permitted to be incurred under the credit facility). In connection with establishment of the credit facility in 2011, the Partnership incurred lender and other third-party costs of approximately $4.8 million. The costs associated with the credit facility have been deferred and are being amortized over the term of the credit facility as interest expense using the effective-interest amortization method for the term loan facility and the straight-line method for the revolving credit facility. See Note 15 ("Fair Value of Financial Instruments") for discussion of the fair value of the interest rate swap agreements. On February 9, 2016, CRLLC and the Partnership entered into a guaranty, pursuant to which CRLLC agreed to guaranty the indebtedness outstanding under the credit facility. If the credit facility becomes due prior to a refinancing by the Partnership, CRLLC is required to pay the indebtedness pursuant to this guaranty. The Partnership's obligation to repay CRLLC for the indebtedness will be pursuant to a promissory note ("the Note"). The terms of the Note will be mutually agreed upon by the parties, provided, the term will be the lesser of two years or such time that the Partnership obtains third-party financing ("New Debt") of at least $125.0 million on terms acceptable to the Partnership with a term of greater than one year from the inception of the New Debt.
