SCHN 2021 Form 10-K

27 / Schnitzer Steel Industries, Inc. Form 10-K 2021 In addition, previous operations by us, predecessor entities, or others at facilities that we currently or formerly owned, operated, or otherwise used may have caused contamination from hazardous substances. As a result, we are exposed to possible claims, including government fines and penalties, costs for investigation and clean-up activities, claims for natural resources damages, and claims by third parties for personal injury and property damage, under environmental laws and regulations, especially for the remediation of waterways and soil or groundwater contamination. These laws can impose liability for the cleanup of hazardous substances even if the owner or operator was neither aware of nor responsible for the release of the hazardous substances. We have, in the past, been found not to be in compliance with certain of these laws and regulations, and have incurred liabilities, expenditures, fines, and penalties associated with such violations. In December 2000, we were notified by the EPA that we are one of the potentially responsible parties that owns or operates, or formerly owned or operated, sites which are part of or adjacent to the Portland Harbor Superfund site. Further, we have been notified that we are or may be a potentially responsible party at sites other than Portland Harbor currently or formerly owned or operated by us or at other sites where we may have responsibility for such costs due to past disposal or other activities. Environmental compliance costs and potential environmental liabilities could have a material adverse effect on our financial condition, results of operations, and cash flows. See also the risk factor “Potential costs related to the environmental cleanup of Portland Harbor may be material to our financial position and liquidity” in this Item 1A and “Contingencies – Environmental” in Note 9 - Commitments and Contingencies in the Notes to the Consolidated Financial Statements in Part II, Item 8 of this report. The Biden Administration and state and local regulators are also emphasizing efforts to strengthen environmental compliance and enforcement, including with respect to clean-up actions under superfund and hazardous waste laws, in overburdened communities that may be disproportionately impacted by adverse health and environmental effects. On September 10, 2021, U.S. EPA Region 9 and the California Environmental Protection Agency announced a joint effort to expand environmental enforcement in overburdened California communities. These initiatives could result in increased enforcement, compliance, and clean-up costs, including increased capital expenditures, at our facilities located at or near such communities. Compliance with existing and future climate change, greenhouse gas, and other air emission laws and regulations may adversely impact our operating results Future legislation or increased regulation regarding climate change and GHG emissions could impose significant costs on our business and our customers and suppliers, including increased energy, capital equipment, emissions controls, environmental monitoring and reporting, and other costs in order to comply with laws and regulations concerning and limitations imposed on climate change and GHG emissions. The potential costs of allowances, taxes, fees, offsets, or credits that may be part of “cap and trade” programs or similar future legislative or regulatory measures are still uncertain and the future of these programs or measures is unknown. For example, in March 2020, the Governor of Oregon issued an executive order directing state agencies to take certain actions to reduce and regulate GHG emissions. Pursuant to this executive order, ODEQ issued a notice of proposed rulemaking in August 2021 that would establish a new Climate Protection Program to limit GHG emissions in the state including from large stationary sources such as our steel mill. In addition, the ODEQ Cleaner Air Oregon (“CAO”) program regulates toxic air emissions from manufacturing facilities located in Oregon. The ODEQ has published a prioritization list of the facilities within the state subject to the CAO program based on emissions inventories that facilities submitted to the ODEQ. The prioritization list established four tiers of risk groups. Our steel mill has been assigned to the first-tier risk group and was selected into the CAO program in 2020. To comply with the CAO program rules, including as they may be revised in the future, facilities may incur expenses to evaluate the risk to the public and may be required to incur additional operating or capital expenditures to mitigate any significant identified risks. Future climate change and GHG laws or regulations could negatively impact our ability (and that of our customers and suppliers) to compete with companies situated in areas not subject to such requirements. Until the timing, scope, and extent of any future laws or regulations becomes known, we cannot predict the effect on our financial condition, operating performance, or ability to compete. Furthermore, even without such laws or regulations, increased awareness and any adverse publicity in the global marketplace about the GHGs emitted by companies in the metals recycling and steel manufacturing industries could harm our reputation and reduce customer demand for our products.
