18. COMMITMENTS AND CONTINGENCIES Environmental Remediation Prior operations included numerous manufacturing and other facilities for which the Company may have responsibility under various environmental laws for the remediation of conditions that may be identified in the future. The Company is involved in environmental remediation and ongoing compliance activities at several sites and has been notified that it is or may be a potentially responsible party at several other sites. Redfield The Company is remediating, under the oversight of Colorado authorities, the groundwater and indoor air at its owned facility in Colorado (the Redfield site or, when referring to remediation activities at or under the facility, the on-site remediation) and residential neighborhoods adjacent to and near the property (the off-site remediation) that have been affected by solvents previously used at the facility. The on-site remediation calls for the operation of a pump and treat system (which prevents migration of contaminated groundwater off the property) as the final remedy for the site, subject to monitoring and periodic review of the on-site conditions and other remedial technologies that may be developed in the future. In 2016, the Company submitted a revised plan to address on-site conditions, including direct treatment of source areas, and received approval from the oversight authorities to begin implementing the revised plan. As the treatment of the on-site source areas progresses, the Company expects to convert the pump and treat system to a passive treatment barrier system. Off-site groundwater concentrations have been reducing over time since installation of the pump and treat system in 2000 and injection of clean water beginning in 2003. However, localized areas of contaminated bedrock just beyond the property line continue to impact off-site groundwater. The modified workplan for addressing this condition includes converting the off-site bioremediation system into a monitoring well network and employing different remediation methods in these recalcitrant areas. In accordance with the workplan, a pilot test was conducted of certain groundwater remediation methods and the results of that test were used to develop more detailed plans for remedial activities in the off-site areas, which were approved by the authorities and are being implemented in a phased manner. The results of groundwater monitoring are being used to evaluate the effectiveness of these activities. The Company continues to implement the expanded remedy workplan that was approved by the oversight authorities in 2015. Based on the progress of the direct remedial action of on-site conditions, the Company has submitted a request to the oversight authorities for permission to convert the perimeter pump and treat active remediation system to a passive one. During the fourth quarter of 2019, a final response was received from the oversight authorities, which will allow the Company to move forward with implementation of the revised plan. The cumulative expenditures for both on-site and off-site remediation through February 1, 2020 were $31.2 million. The Company has recovered a portion of these expenditures from insurers and other third parties. The reserve for the anticipated future remediation activities at February 1, 2020 is $9.6 million, of which $8.8 million is recorded within other liabilities and $0.8 million is recorded within other accrued expenses. Of the total $9.6 million reserve, $5.0 million is for off-site remediation and $4.6 million is for on-site remediation. The liability for the on-site remediation was discounted at 4.8%. On an undiscounted basis, the on-site remediation liability would be $13.8 million as of February 1, 2020 . The Company expects to spend approximately $0.5 million in the next year, $ 0.1 million in each of the following four years and $12.9 million in the aggregate thereafter related to the on-site remediation. Other Various federal and state authorities have identified the Company as a potentially responsible party for remediation at certain other sites. However, the Company does not currently believe that its liability for such sites, if any, would be material. The Company continues to evaluate its estimated costs in conjunction with its environmental consultants and records its best estimate of such liabilities. However, future actions and the associated costs are subject to oversight and approval of various governmental authorities. Accordingly, the ultimate costs may vary, and it is possible costs may exceed the recorded amounts. Litigation The Company is involved in legal proceedings and litigation arising in the ordinary course of business. In the opinion of management, the outcome of such ordinary course of business proceedings and litigation currently pending is not expected to have a material adverse effect on the Companys results of operations or financial position. Legal costs associated with litigation are generally expensed as incurred.
