Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt: In July 2010, the Partnership issued $405 million of 9.125% senior unsecured notes, maturing in 2018, in a private placement, including $5.6 million of Original Issue Discount to yield 9.375%. Concurrently with this offering, the Partnership entered into a new $1,435 million credit agreement (the "2010 Credit Agreement”), which included a $1,175 million senior secured term loan facility and a $260 million senior secured revolving credit facility. The net proceeds from the offering of the notes, along with borrowings under the 2010 Credit Agreement, were used to repay in full all amounts outstanding under the previous credit facilities. The facilities provided under the 2010 Credit Agreement are collateralized by substantially all of the assets of the Partnership. Terms of the 2010 Credit Agreement included a reduction in the Partnership's previous $310 million revolving credit facilities to a combined $260 million facility. Under the 2010 Credit Agreement, the Canadian portion of the revolving credit facility has a limit of $15 million. U.S. denominated loans made under the revolving credit facility bear interest at a rate of LIBOR plus 400 basis points (bps) (with no LIBOR floor). Canadian denominated loans made under the Canadian portion of the facility also bear interest at a rate of LIBOR plus 400 bps (with no LIBOR floor). The revolving credit facility, which matures in July 2015, also provides for the issuance of documentary and standby letters of credit. The Amended 2010 Credit Agreement requires the Partnership to pay a commitment fee of 50 bps per annum on the unused portion of the credit facilities. In February 2011, the Partnership amended the 2010 Credit Agreement (as so amended, the “Amended 2010 Credit Agreement”) and extended the maturity date of the U.S. term loan portion of the credit facilities by one year. The extended U.S. term loan, which amortizes at $11.8 million per year beginning in 2011, matures in December 2017 and bears interest at a rate of LIBOR plus 300 bps, with a LIBOR floor of 100 bps. In May 2012, the Partnership prepaid $16.0 million of long-term debt to meet its obligation under the Excess Cash Flow ("ECF") provision of the Credit Agreement. As a result of this prepayment, as well as the August 2011 $18.0 million debt prepayment, the Partnership has no scheduled term-debt principal payments until the second quarter of 2014. The Partnership's $405 million of senior unsecured notes pay interest semi-annually in February and August, with the principal due in full on August 1, 2018. The notes may be redeemed, in whole or in part, at any time prior to August 1, 2014 at a price equal to 100% of the principal amount of the notes redeemed plus a “make-whole” premium together with accrued and unpaid interest, if any, to the redemption date. Thereafter, the notes may be redeemed, in whole or in part, at various prices depending on the date redeemed. Prior to August 1, 2013, up to 35% of the notes may be redeemed with the net cash proceeds of certain equity offerings at 109.125%. The Amended 2010 Credit Agreement requires the Partnership to maintain specified financial ratios, which if breached for any reason, including a decline in operating results, could result in an event of default under the agreement. The most critical of these ratios is the Consolidated Leverage Ratio which is measured on a trailing-twelve month quarterly basis. The Consolidated Leverage Ratio is set at 6.0x consolidated total debt- (excluding the revolving debt) to-Consolidated EBITDA and will remain at that level through the end of the third quarter in 2013, and the ratio will decrease further each fourth quarter beginning with the fourth quarter of 2013. As of July 1, 2012, the Partnership’s Consolidated Leverage Ratio was 3.75x, providing $154.2 million of consolidated EBITDA cushion on the ratio as of the end of the second quarter. The Partnership was in compliance with all other covenants under the Amended 2010 Credit Agreement as of July 1, 2012. The Amended 2010 Credit Agreement also includes provisions that allow the Partnership to make restricted payments of up to $20 million annually, so long as no default or event of default has occurred and is continuing. These restricted payments are not subject to any specific covenants. Additional restricted payments are allowed to be made based on an Excess-Cash-Flow formula, should the Partnership’s pro-forma Consolidated Leverage Ratio be less than or equal to 4.50x. Per the terms of the indenture governing the Partnership's notes, the ability to make restricted payments in 2012 and beyond is permitted should the Partnership's trailing-twelve-month Total-Indebtedness-to-Consolidated-Cash-Flow Ratio be less than or equal to 4.75x, measured on a quarterly basis. In addition to the above, among other covenants and provisions, the Amended 2010 Credit Agreement contains an initial three-year requirement (from July 2010) that at least 50% of our aggregate term debt and senior notes be subject to either a fixed interest rate or interest rate protection.
