The closure process is a requirement of both the Deer Creek lease and the State of Colorado, a permitting authority for such facilities. The closure cost estimate, in current dollars, was completed by an approved independent consultant experienced in estimating closure costs for water disposal operations and the estimated amount was, subsequent to June 30, 2012, approved by the State of Colorado. A present value discount has not been taken as the estimated closure costs, excluding regulatory changes and inflation adjustments, are anticipated to remain fairly consistent over the operational life of the facility.   The Company reviews the contingent asset retirement obligation on a recurring basis and records changes in the period incurred. At June 30, 2013, the estimated closure costs were again reviewed and the only adjustment was a 1.8% inflation adjustment as required under agreement with the Colorado Department of Public Health and Environment, increasing the asset retirement obligation to $417,400, AESs approximate 75% share of the $566,000 estimated closure costs for both the Deer Creek facility and the adjacent Goodwin Solid Waste facility (Goodwin is not owned by AES). The significant unobservable inputs used in the fair value measurement of the Companys fair value calculation for the asset retirement obligation include the estimated cost to close the Deer Creek facility in accordance with state approved closure plans, the projected timing of the closure and the discount rate applied. Significant changes in any of those inputs in isolation would result in a significantly different fair value measurement. See Note 5 Alanco Energy Services for additional discussion on AES operations.   The laws of the State of Colorado require companies to meet environmental and asset retirement obligations by selecting an approved payment method. The Company has elected to meet its obligation by making an initial payment of approximately $25,300 and quarterly payments of approximately $4,700 into a trust that over the expected lease period will build liquid assets to meet the asset retirement obligation.falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for (1) legal obligations associated with the disposal or removal of a long-lived asset from service that result from the acquisition, construction, or development or from the normal operation of a long-lived asset (except obligations of a lessee in connection with leased property that are minimum lease payments or contingent rentals, or obligations that arise solely from a plan to sell or otherwise dispose of a long-lived asset); and (2) certain environmental remediation liabilities that resulted from the improper or other-than-normal operation of a long-lived asset.
