Income Tax Disclosure [Abstract]
Income Taxes	16. Income Taxes As a limited partnership, the Partnership is not subject to federal and state income taxes. Income tax attributable to the Partnership’s taxable income, which may differ significantly from income for financial statement purposes, is assessed at the individual level of the unitholder. The Partnership is subject to a statutory requirement that non-qualifying income, as defined by the Internal Revenue Code, cannot exceed 10% of total gross income for the calendar year. If non-qualifying income exceeds this statutory limit, the Partnership would be taxed as a corporation. The non-qualifying income did not exceed the statutory limit in any period. Certain activities that generate non-qualifying income are conducted through a taxable corporate subsidiary, LGWS. Current and deferred income taxes are recognized on the earnings of LGWS. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates. As a result of the recognition of net deferred tax liabilities associated with the preliminary purchase price allocation related to the acquisition of PMI, the Partnership released $5.2 million of its valuation allowance against deferred tax assets in the second quarter of 2014. Since the purchase price allocation is preliminary, such release is subject to change and such change could be material. Further, in conjunction with the Partnership’s ongoing review of its actual results and anticipated future earnings, the Partnership continuously reassesses the possibility of releasing the remaining $1.9 million valuation allowance on its deferred tax assets. It is reasonably possible that a significant portion of the valuation allowance will be released within the next twelve months. The valuation allowance release was partially offset by the impact of certain nondeductible acquisition costs and the taxable gain on the sale of the Lubricants Business for which a portion related to nondeductible goodwill. For the three and six months ended June 30, 2013, the Partnership recorded an increase in the valuation allowance of $0.1 million and $0.5 million, respectively.
