Income Tax Disclosure [Abstract]
Income Tax Disclosure	INCOME TAXES We evaluate our estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. The estimated annual effective tax rate is adjusted quarterly based upon actual results and updated operating forecasts. Consequently, based upon the mix and timing of our actual earnings compared to annual projections, our effective tax rate may vary quarterly and may make quarterly comparisons not meaningful. A tax expense or benefit unrelated to the current year income or loss is recognized in its entirety as a discrete item of tax in the period identified. The quarterly income tax provision is generally comprised of tax expense on income or tax benefit on loss at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items. The effective tax rates for continuing operations for the three months ended March 31, 2013 was a 35.5% benefit on loss compared to a 37.9% expense on income for the three months ended March 31, 2012. The effective tax rates for the three month periods ended March 31, 2013 and March 31, 2012 approximate the federal statutory rate of 35.0%, plus our effective blended state tax rate of approximately 3.0%. For the three months ended March 31, 2012, our permanent deductions, largely percentage depletion, were offset by nondeductible items, primarily officers' compensation. For the three months ended March 31, 2013, the nondeductible item for officers' compensation exceeded our deduction for percentage depletion, thereby reducing our tax benefit rate. Additionally, state statutory limits on the utilization of our net operating losses resulted in a reduced state tax benefit. There were no significant discrete items recorded during the three months ended March 31, 2013 or 2012. As of March 31, 2013, we had a gross liability for unrecognized tax benefits of $0.2 million, unchanged from the amount recorded at December 31, 2012. If recognized, this liability would affect our effective tax rate. This liability is reflected in other accrued expenses on our accompanying balance sheets. We expect our remaining liability for uncertain tax positions to decrease in the next twelve months due to the expiration of statute of limitations. As of the date of this filing, we are current with our income tax filings in all applicable state jurisdictions and currently have no state income tax returns in the process of examination.
