 actions in the Lower Passaic River Study Area. EnPro Holdings and approximately 70 of the numerous other PRPs, known as the Cooperating Parties Group, are parties to a May 2007 Administrative Order on Consent with the EPA to perform a Remedial Investigation/Feasibility Study (“RI/FS”) of the contaminants in the Lower Passaic River Study Area. In September 2018, EnPro Holdings withdrew from the Cooperating Parties Group but remains a party to the May 2007 Administrative Order on Consent. The RI/FS was completed and submitted to the EPA at the end of April 2015. The RI/FS recommends a targeted dredge and cap remedy with monitored natural recovery and adaptive management for the Lower Passaic River Study Area. The cost of such remedy is estimated to be $726 million.

Previously, on April 11, 2014, the EPA released its Focused Feasibility Study (the “FFS”) with its proposed plan for remediating the lower eight miles of the Lower Passaic River Study Area, which is also referred to as Operating Unit 2 ("OU2"). The FFS calls for bank-to-bank dredging and capping of the riverbed of that portion of the river and estimates a range of the present value of aggregate remediation costs of approximately $953 million to approximately $1.73 billion, although estimates of the costs and the timing of costs are inherently imprecise. On March 3, 2016, the EPA issued the final Record of Decision ("ROD") as to the remedy for OU2, with the maximum estimated cost being reduced by the EPA from $1.73 billion to $1.38 billion, primarily due to a reduction in the amount of cubic yards of material that will be dredged. In October 2016, Occidental Chemical Corporation, the successor to the entity that operated the Diamond Alkali chemical manufacturing facility, reached an agreement with the EPA to develop the design for this proposed remedy at an estimated cost of $165 million. The EPA has estimated that it will take approximately four years to develop this design. On June 30, 2018, Occidental Chemical Corporation sued over 120 parties, including the Company, in the United States District Court for New Jersey seeking recovery of response costs under the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"). On April 14, 2021, the EPA issued its proposed remedy for the remaining portions of the Lower Passaic River
