 emergencies, reliability must run agreements, etc.) as determined by the United States Department of Energy, a public utility commission, or independent system operator.In November 2024, Edison Electric Institute, on behalf of its members, submitted 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 rule through litigation pending in the U.S. Court of Appeals for the Eighth Circuit. The outcome of this case may affect our compliance plans. In February 2025, the U.S. Court of Appeals for the Eighth Circuit granted the EPA's request to hold the ELG rule litigation in abeyance. In April 2025, the EPA filed a motion with the U.S. Court of Appeals for the Eighth Circuit requesting that they continue to hold the case in abeyance until June 30, 2025. The Supplemental ELG Rule remains in effect during the pendency of the legal challenge. See the Federal Deregulatory Actions discussion above for more information regarding potential deregulatory actions regarding this rule.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 remediation of manufactured gas plant sites. Accordingly, we have established regulatory assets for costs associated with these sites.
