Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | NOTE 18. COMMITM ENTS AND CONTINGENCIES At any given time, we are subject to claims and actions incidental to the operations of our business. Based on information currently available, management believes the company is not a party to any legal proceeding that could have a materially adverse effect on our consolidated financial position, operating results, or net cash flow. ENVIRONMENTAL MATTER Pursuant to a 2002 Asset Purchase Agreement under which Sappi Cloquet LLC (Sappi) purchased our Cloquet, Minnesota pulp and paper mill (the Plant), we agreed to indemnify Sappi from certain environmental liabilities accruing from the pre-sale operations of the Plant. In February 2021, we were notified by Sappi that the Environmental Protection Agency (EPA) contacted Sappi about the opportunity to participate with the Minnesota Pollution Control Agency (MPCA) and the EPA in a voluntary federal sediment remediation program under the Great Lakes Legacy Act (GLLA) for a project in the St. Louis River Area of Concern, which runs from Cloquet, Minnesota to Lake Superior. The GLLA is a sediment remediation program administered by EPA that provides up to 65% federal funding for the remediation of contaminated sediments in the Great Lakes region. The GLLA program requires at least 35% cash or in-kind contributions from non-federal sponsors (NFS). The EPA’s invitation to Sappi made no demands on or claims against Sappi, nor have the EPA or the MPCA made any demands or claims against PotlatchDeltic. The identified sediment remediation project (the Project) at Thomson Reservoir is downstream from the Plant. The Plant was identified for potential partnership with the EPA and the MPCA on the Project based on the Plant’s historic direct discharges of wastewater and leachate from the Plant’s landfill into the St. Louis River prior to the re-routing of the discharges in 1979 to a public wastewater treatment facility. After multiple discussions with the MPCA and completion of our extensive due diligence on this matter, we informed the MPCA in January 2023 that we were int erested in voluntarily participating in the Project, subject to an equitable division with the MPCA of the NFS share of the costs and accrued $5.6 million at December 31, 2022 for our estimated contribution to the Project. We executed a Project agreement with the EPA and the MPCA in October 2023 and estimated our share of the total Project costs between $5.6 million and $6.7 million. In accordance with the Project agreement, we made a $3.4 million payment in November 2023, for our initial share of the Project costs. At December 31, 2023, we have accrued $2.2 million for our estimated remaining contribution to the Project, all of which is included in accounts payable and accrued liabilities in our Consolidated Balance Sheets. While it is reasonably possible that costs may change as the Project develops and work contracts are executed, we are unable to estimate at this time the amount of change, if any, which may be required for our share of this matter in the future.
