The value of qualified pollution control facilities, for the purpose of ad valorem property taxation, is deemed to be its salvage value (the estimated fair market value), if any, which could be realized upon the voluntary sale or other disposition of the property when it can no longer be used for the purpose for which it was designed. Salvage value should not exceed 0.5 percent of the acquisition value of such facilities.1
