Our operations are subject to increasingly stringent environmental, health, and safety laws. These include laws that impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage, and disposal of regulated materials, and the investigation and remediation of contaminated soil, surface water, and groundwater. Failure to maintain or achieve compliance with these laws or with the permits required for our operations could result in substantial increases in operating costs and capital expenditures. In addition, we may be subject to fines and civil or criminal sanctions, third party claims for property damage or personal injury, worker's compensation or personal injury claims, cleanup costs, or temporary or permanent discontinuance of operations. Certain of our facilities are located in industrial areas, have a history of heavy industrial use, and have been in operation for many years and, over time, we and other predecessor operators of these facilities have generated, used, handled, and disposed of hazardous and other regulated wastes. Environmental liabilities could exist, including cleanup obligations at these facilities or at off-site locations where materials from our operations were disposed of, which could result in future expenditures that cannot be currently quantified and which could have a material adverse effect on our financial position, results of operations, or cash flows. Such liabilities may be imposed without regard to fault or the legality of a party's conduct and may, in certain circumstances, be joint and several. Future changes to environmental, health, and safety laws, including those related to climate change, could result in material liabilities and costs, constrain operations, or make operations more costly for us, our suppliers, and our customers.
In October 2011, the United States Environmental Protection Agency (the "EPA") named JT Ryerson as one of more than 100 businesses that may be a potentially responsible party for the Portland Harbor Superfund Site. See Note 12: Commitments and Contingencies in the notes to the consolidated financial statements included in Part II, Item 8 of this Report on Form 10-K. As the EPA has not yet allocated responsibility for the contamination among the potentially responsible parties, including JT Ryerson, we do not currently have sufficient information available to us to determine whether the Record of Decision will be executed as currently stated, whether and to what extent JT Ryerson may be held responsible for any of the identified contamination, and how much (if any) of the final plan's costs might ultimately be allocated to JT Ryerson. Therefore, management cannot predict the ultimate outcome of this matter or estimate a range of potential loss at this time.
