Asset Retirement Obligations	Note 7: Asset Retirement Obligations Currently, we have an obligation to plug and abandon a wastewater injection well at one of our Chemical Business facilities when the permit expires. We are also contractually obligated through at least December 2053 to pay a portion of the operating costs of a municipally owned wastewater pipeline currently being constructed that will serve our chemical production facility located in El Dorado, Arkansas (the “El Dorado Facility”). Additionally, we have certain facilities in our Chemical Business that contain asbestos insulation around certain piping and heated surfaces, which we plan to maintain or replace, as needed, with non-asbestos insulation through our standard repair and maintenance activities to prevent deterioration. Currently, there is insufficient information to estimate the fair value for most of our asset retirement obligations (“ARO”). In addition, we currently have no plans to discontinue the use of these facilities, and the remaining life of the facilities is indeterminable. As a result, a liability for only a minimal amount relating to AROs associated with these facilities has been established. However, we will continue to review these obligations and record a liability when a reasonable estimate of the fair value can be made. In addition, our Chemical Business owns working interests in certain natural gas properties. We recognized AROs associated with the obligation to plug and abandon wells when the natural gas reserves in the wells are depleted. At March 31, 2013 and December 31, 2012, our accrued liability for AROs was $161,000 and $154,000, respectively.
