 its proposed remedy for the remaining portions of the Lower Passaic River 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. Following 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 September 30, 2025 was $0.7 million, which is for work remaining at the site that is not covered by the settlement. 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, including two EPA-designated “priority” mines located in the Cameron Chapter of the Navajo Nation and six EPA-designated “non-priority” mines located in the more remote

Bodaway Gap Chapter of the Navajo Nation, which are collectively one of the 21 sites referenced above. The former operator conducted operations at these mines from 1954 to 1957, prior to Enpro's formation in 2002. In the 1990s, remediation work performed by others consisted of capping the exposed areas of these mines.
