 Study Area (i.e., the upper nine miles of the river) with an estimated present value cost of approximately $441 million. The proposed remedy would involve dredging and capping of the river sediment as an interim remedy followed by a period of monitoring to evaluate the response of the river system to the interim remedy.When the EPA initiated the allocation process in 2017, it explained that a fair, carefully structured, information-based allocation was necessary to promote settlements. With the completion of the allocation process, in the second quarter of 2021 the EPA began settlement negotiations with the parties that participated in the allocation process, including EnPro Holdings, to resolve the settling parties’ liability as to the full 17-mile Lower Passaic River Study Area (including OU2). In September 2022, EnPro Holdings paid $5.9 million as part of a settlement between those parties and the EPA. The court approved and entered the settlement on December 18, 2024, and two parties have appealed the court's order. The payment will be held in escrow until all appeals have been resolved. Our reserve for the Lower Passaic River Study Area at March 31, 2025 was $0.7 million. Further adjustments to our reserve for the site are possible as new or additional information becomes available. Except with respect to the Lower Passaic River Study Area, we are unable to estimate a reasonably possible range of loss related to any other contingent environmental liability based on our prior ownership of Crucible. See the section entitled “Crucible Steel Corporation a/k/a Crucible, Inc.” in this footnote for additional information.Arizona Uranium MinesEnPro Holdings has received notices from the EPA asserting that it is a potentially responsible party under the CERCLA as the successor to a former operator of eight uranium mines in Arizona. The former operator conducted operations at the mines from 1954 to 1957. In the 1990s, remediation work performed by others at these sites consisted of capping the exposed areas of the mines. We have previously reserved amounts of probable loss associated with these mines, principally including the cost of the investigative work to be conducted at such mines. We entered into an Administrative Settlement Agreement and Order on Consent for Interim Removal Action with the EPA effective November 7, 2017 for the performance of this work. We entered into a First Modification of Original Administrative Settlement Agreement and Order on Consent effective July 8, 2022 for the performance of Engineering Evaluations and Cost Analyses of potential
