 million as part of a settlement between those parties and EPA. The court approved and entered the settlement on December 18, 2024. The payment will be held in escrow until the deadline for filing an appeal has passed and all appeals (as applicable) have been resolved. Our reserve for the Lower Passaic River Study Area at December 31, 2024 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 Mines  EnPro 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 remedial options at each of the sites. In 2020, EPA initiated group discussions with EnPro Holdings and other potentially responsible parties to resolve various technical issues, including the development of cleanup standards. Based on these discussions and subsequent discussions with other responsible parties with similar sites, we have concluded that further remedial work beyond maintenance of and minor repairs to the existing caps is probable, and we have evaluated the feasibility of various remediation scenarios. Our reserve at December 31, 2024 for this site was $12.2 million, which reflects the low end of the range of our reasonably likely liability with respect to these sites. We are not able at this time to estimate the upper end of a range of liability with respect to these sites.On October 18, 2021, the United States District Court for the District
