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 benefit on loss at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items. The effective tax rate for continuing operations for the three months ended March 31, 2015 was a 38.6% expense on income compared to a 38.8% benefit on loss for the three months ended March 31, 2014. The effective tax rate for the three months ended March 31, 2015 is based upon a full year forecasted tax provision on income and is greater than the statutory rate, primarily due to state taxes and nondeductible officers' compensation, partially offset by percentage depletion and domestic production deduction. The effective tax rate for the three months ended March 31, 2014 differs from the statutory rate primarily due to percentage depletion and domestic production deduction partially offset by state taxes and nondeductible officers' compensation. There were no significant discrete items recorded during the three months ended March 31, 2015 or March 31, 2014. As of March 31, 2015, we had no liability for unrecognized tax benefits. As of the date of this report, we are current with our income tax filings in all applicable state jurisdictions and are not currently under any state income tax examinations. We continue voluntary participation in the Internal Revenue Service’s ("IRS") Compliance Assurance Program for the 2014 and 2015 tax years. The IRS has notified us of full acceptance of our 2013 return with no changes.

The estimated annual effective tax rate is adjusted quarterly based upon actual results and updated operating forecasts.

The quarterly income tax provision is generally comprised of tax expense on income or benefit on loss at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items.
