77 / Schnitzer Steel Industries, Inc. Form 10-K 2021 Other Legacy Environmental Loss Contingencies The Company’s environmental loss contingencies as of August 31, 2021 and 2020, other than Portland Harbor, include actual or possible investigation and remediation costs from historical contamination at sites currently or formerly owned or formerly operated by the Company or at other sites where the Company may have responsibility for such costs due to past disposal or other activities (“legacy environmental loss contingencies”). These legacy environmental loss contingencies relate to the potential remediation of waterways and soil and groundwater contamination and may also involve natural resource damages, governmental fines and penalties, and claims by third parties for personal injury and property damage. The Company has been notified that it is or may be a potentially responsible party at certain of these sites, and investigation and remediation activities are ongoing or may be required in the future. The Company recognizes a liability for such matters when the loss is probable and can be reasonably estimated. When investigation, allocation, and remediation activities are ongoing or where the Company has not yet been identified as having responsibility or the contamination has not yet been identified, it is reasonably possible that the Company may need to recognize additional liabilities in connection with such sites but the Company cannot currently reasonably estimate the possible loss or range of loss absent additional information or developments. Such additional liabilities, individually or in the aggregate, may have a material adverse effect on the Company’s results of operations, financial condition, or cash flows. In fiscal 2018, the Company accrued $4 million for the estimated costs related to remediation of shredder residue disposed of in or around the 1970s at third-party sites located near each other. Investigation activities have been conducted under oversight of the applicable state regulatory agency. As of August 31, 2021 and 2020, the Company had $4 million accrued for this matter. It is reasonably possible that the Company may recognize additional liabilities in connection with this matter at the time such losses are probable and can be reasonably estimated. The Company previously estimated a range of reasonably possible losses related to this matter in excess of current accruals at between zero and $28 million based on a range of remedial alternatives and subject to development and approval by regulators of a specific remedy implementation plan. However, subsequent to the development of those remedial alternatives, the Company performed additional investigative activities under new state requirements that have the potential to impact the required remedial actions and associated cost estimates pending further investigation, analysis, and discussion by the Company and regulators. The Company is investigating whether a portion or all of the current and future losses related to this matter, if incurred, are covered by existing insurance coverage or may be offset by contributions from other responsible parties. In addition, the Company’s loss contingencies as of August 31, 2021 and 2020 included $19 million and $8 million, respectively, for the estimated costs related to environmental matters in connection with a closed facility owned and previously operated by an indirect, wholly-owned subsidiary, including monitoring and remediation of soil and groundwater conditions. Investigation and remediation activities have been conducted under the oversight of the applicable state regulatory agency and are on-going, and the Company has also been working with state and local officials with respect to the protection of public and private water supplies. As part of its activities relating to the protection of public water supplies, the Company has agreed to reimburse the municipality for certain studies and plans and is in discussions with the municipality regarding funding for wellhead treatment. The Company accrued $17 million in fiscal 2021 for incremental estimated remediation costs and for funding for wellhead treatment, which was offset by payments during fiscal 2021 including payment of penalties in the amount of $2.7 million pursuant to a previously agreed settlement. It is reasonably possible that the Company may recognize additional liabilities in connection with this matter at the time such additional losses are probable and can be reasonably estimated. However, the Company cannot reasonably estimate at this time the possible additional loss or range of possible additional losses associated with this matter pending the on-going implementation of the approved remediation plan for soil and groundwater conditions, determination of the costs for wellhead treatment based on receipt and award of contractor bids, and finalization of discussions regarding the Company’s share of funding for such costs. In addition, the Company’s loss contingencies as of August 31, 2021 and 2020 included $8 million and less than $1 million, respectively, for the estimated costs related to remediation of a site a portion of which was previously leased to and operated by an indirect, whollyowned subsidiary. In connection with settlement of a lawsuit relating to allocation of the remediation costs, the Company’s subsidiary agreed to perform the remedial action related to metals contamination on the site estimated to cost approximately $7.9 million, and another potentially liable party agreed to perform the remedial action related to creosote contamination at the site. As part of the settlement, other potentially liable parties agreed to make payments totaling approximately $7.6 million to fund the remediation of the metals contamination at the site in exchange for a release and indemnity. This amount was fully funded into a client trust account for the Company’s subsidiary in December 2020. See “Other Assets” in Note 2 - Summary of Significant Accounting Policies for further discussion of this client trust account. It is reasonably possible that the Company may recognize additional liabilities in connection with this matter at the time such additional losses are probable and can be reasonably estimated. However, the Company cannot reasonably estimate at this time the possible additional loss or range of possible additional losses associated with this matter pending completion, approval and implementation of the remediation action plan.
