Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Under ASC 740, Income Taxes (“ASC 740”) we used an estimated annual tax rate to record income taxes for the three and nine months ended September 30, 2020 and September 30, 2019. Our effective tax rate was 16.9% and 32.0% for the three and nine months ended September 30, 2020, respectively, compared to 18.3% and 21.9% for the three and nine ended September 30, 2019, respectively. The difference between the effective tax rate and the statutory rate is generally attributable to permanent differences and discrete items. The change in our effective tax rate for the three and nine months ended September 30, 2020 as compared to the three and nine months ended September 30, 2019 was primarily due to tax benefit for federal tax credits attributable to the Company’s biodiesel blending operations that were re-enacted in December 2019, reversal of a valuation allowance for deferred tax assets in partnership investments due to changes in the future realizability of deferred tax basis differences, and expected net operating loss carryback provided under the CARES Act which allows the Company to recover federal taxes paid in prior years at a 35% tax rate creating a 14% tax rate benefit.On March 27, 2020, the Coronavirus Aid Relief, and Economic Security Act (the "CARES Act") was enacted into law.  The CARES Act includes several significant provisions for corporations, including the usage of net operating losses, interest deductions and payroll benefits.  The Company recognized $16.8 million of current federal income tax benefit for the nine months ended September 30, 2020, attributable to anticipated tax refunds from net operating loss carryback to prior 35% tax rate years under the CARES Act. Additionally, we recorded an federal income tax receivable totaling $165.6 million as of September 30, 2020 related to the federal net operating loss carryback.
