 a petition for reconsideration to the EPA regarding the CRL provisions in the Supplemental ELG Rule in an effort to codify the rule interpretations articulated by the EPA staff during informational conference calls on this issue. We are still awaiting either a rule revision or clear written guidance from the EPA about the Supplemental ELG Rule CRL provisions to determine the applicability and potential compliance costs for inactive/closed landfills. Numerous parties have challenged the 2024 Supplemental ELG Rule through litigation in SWEPCO v. U.S. EPA pending in the United States Court of Appeals for the Eighth Circuit. The outcome of this case may affect our compliance plans. This case has been held in abeyance since February 2025. In August 2025, the court granted the EPA's motion to continue to hold this case in abeyance and required the EPA to file regular periodic reports. The Supplemental ELG Rule remains in effect during the pendency of the legal challenge. In September 2025, the EPA announced it intends to issue a proposed rule and a companion direct final rule to modify certain 2024 ELG Rule provisions. The proposed rule would (1) extend compliance deadlines for the zero-discharge requirements in the 2024 ELG Rule, (2) update provisions to allow permitting authorities site-specific flexibility to extend deadlines due to unexpected demand, and (3) solicit data from the electric utility industry about the viability of compliance pathways to evaluate economic achievability and energy reliability. The companion direct final rule would extend the date from December 31, 2025 to December 31, 2031 for existing coal-fired steam electric power plants to submit a NOPP for the permanent cessation of coal.Land QualityManufactured Gas Plant RemediationWe have identified sites at which we or a predecessor company owned or operated a manufactured gas plant or stored manufactured gas. We have also identified other sites that may have been impacted by historical manufactured gas plant activities. We are responsible for the environmental remediation of these sites. We are also working with the state of Wisconsin in our investigation and remediation planning. These sites are at various stages of investigation, monitoring, remediation, and closure.The future costs for detailed site investigation, future remediation, and monitoring are dependent upon several variables including, among other things, the extent of remediation, changes in technology, and changes in regulation. Historically, our regulators have allowed us to recover incurred costs, net of insurance recoveries and recoveries from potentially responsible parties, associated with the
