We have been notified by federal and state environmental agencies and by private parties that we may be a potentially responsible party (PRP) in connection with the environmental investigation and remediation of certain sites. While government agencies frequently assert that PRPs are jointly and severally liable at these sites, in our experience, the interim and final allocations of liability costs are generally made based on the relative contribution of waste. We may also initiate corrective and preventive environmental projects of our own to ensure safe and lawful activities at our operations. We believe that compliance with current governmental regulations at all levels will not have a material adverse effect on our financial position, results of operations or cash flows. In September 2007, the United States District Court for the Western District of Kentucky (Court) in the case of Westlake Vinyls, Inc. v. Goodrich Corporation, et al ., held that PolyOne must pay the remediation costs at the former Goodrich Corporation Calvert City facility (now largely owned and operated by Westlake Vinyls, Inc. (Westlake Vinyls)), together with certain defense costs of Goodrich Corporation. The rulings also provided that PolyOne can seek indemnification for contamination attributable to Westlake Vinyls. Following the rulings, the parties to the litigation agreed to settle all claims regarding past environmental costs incurred at the site. The settlement agreement provides a mechanism to pursue allocation of future remediation costs at the Calvert City site to Westlake Vinyls. We will adjust our accrual, in the future, consistent with any such future allocation of costs. Additionally, we continue to pursue available insurance coverage related to this matter and recognize gains as we receive reimbursement. The environmental obligation at the site arose as a result of an agreement between The B.F. Goodrich Company (n/k/a Goodrich Corporation) and our predecessor, The Geon Company, at the time of the initial public offering in 1993. Under the agreement, The Geon Company agreed to indemnify Goodrich Corporation for certain environmental costs at the site. Neither PolyOne nor The Geon Company ever operated the facility. Since 2009, PolyOne, along with respondents Westlake Vinyls, and Goodrich Corporation, have worked with the United States Environmental Protection Agency (USEPA) on the investigation of contamination at the site as well as the evaluation of potential remedies to address the contamination. The USEPA issued its Record of Decision (ROD) in September 2018, selecting a remedy consistent with our accrual assumptions. In April 2019, the respondents signed an Administrative Settlement Agreement and Order on Consent with the USEPA to conduct the remedial actions at the site. In February 2020, the three companies agreed to a draft Consent Decree and draft remedial action Work Plan, which are currently under USEPA review. Our current reserve of $99.6 million is consistent with the USEPA's estimates contained in the ROD. On March 13, 2013, PolyOne acquired Spartech Corporation (Spartech). One of Spartech's subsidiaries, Franklin-Burlington Plastics, Inc. (Franklin-Burlington), operated a plastic resin compounding facility in Kearny, New Jersey, located adjacent to the Passaic River. The USEPA requested that companies located in the area of the lower Passaic River, including Franklin-Burlington, cooperate in an investigation of contamination of approximately 17 miles of the lower Passaic River Study Area (LPRSA). In response, Franklin-Burlington and approximately 70 other companies (collectively, the Cooperating Parties) agreed, pursuant to an Administrative Order on Consent (AOC) with the USEPA, to assume responsibility for development of a Remedial Investigation and Feasibility Study of the LPRSA. Franklin-Burlington has not admitted to any liability or agreed to bear any other costs for remediation or natural resource damage. In 2015, the Cooperating Parties submitted to the USEPA a remedial investigation report and feasibility study for the LPRSA and are currently engaged in technical discussions with the USEPA regarding those documents. Neither of those documents contemplates who is responsible for remediation or how such costs might be allocated to PRPs. In March 2016, the USEPA issued a ROD selecting a remedy for an eight-mile portion of the LPRSA at an estimated and discounted cost of $1.4 billion. On March 31, 2016, the USEPA sent a Notice of Potential Liability to over 100 companies, including Franklin-Burlington, and several municipalities for this eight-mile portion. In September 2016, the USEPA reached an agreement with Occidental Chemical Corporation (OCC), which orders OCC to conduct the remedial design for the lower eight-mile portion of the Passaic River. In September 2017, the USEPA sent a letter to over 80 companies, including Franklin-Burlington, indicating that the USEPA would engage the recipients in an allocation process for the lower eight miles of the LPRSA and has engaged a third-party allocator as part of that process. Along with other parties, Franklin-Burlington is participating in the development of this allocation process with the allocator retained by the USEPA, and this process is expected to continue through at least 2020. On June 30, 2018, OCC, independent of the USEPA, filed suit against 100 named entities, including Franklin-Burlington, seeking contribution for past and future costs associated with the remediation of the lower eight-mile portion of the LPRSA. Based on the currently available information, we have not identified evidence that Franklin-Burlington contributed any of the primary contaminants of concern to the lower Passaic River. A timeline as to when an allocation of the remedial costs may be determined is not yet known and any allocation to Franklin-Burlington has not been determined. As a result of these uncertainties, we are unable to estimate a liability related to this matter and, as of March 31, 2020, we have not accrued for costs of remediation related to the lower Passaic River. During the three months ended March 31, 2020, PolyOne recognized $0.3 million of expense related to environmental remediation costs, compared to $2.1 million recognized during the three months ended March 31, 2019. During the three months ended March 31, 2020, PolyOne received $0.2 million of insurance recoveries for previously incurred environmental costs. No such reimbursements were recovered during the three months ended March 31, 2019 . These expenses and insurance recoveries are included within Cost of sales within our Condensed Consolidated Statements of Income. Insurance recoveries are recognized as a gain when received. Our Condensed Consolidated Balance Sheets include accruals totaling $109.7 million and $112.0 million as of March 31, 2020 and December 31, 2019, respectively, based on our estimates of probable future environmental expenditures relating to previously contaminated sites. These undiscounted amounts are included in Accrued expenses and other current liabilities and Other non-current liabilities on the accompanying Condensed Consolidated Balance Sheets. The accruals represent our best estimate of probable future costs that we can reasonably estimate, based upon currently available information and technology and our view of the most likely remedy. Depending upon the results of future testing, completion and results of remedial investigation and feasibility studies, the ultimate remediation alternatives undertaken, changes in regulations, technology development, new information, newly discovered conditions and other factors, it is reasonably possible that we could incur additional costs in excess of the amount accrued at March 31, 2020. However, such additional costs, if any, cannot be currently estimated.
