S rules. The GHG and MATS cases continue through the normal procedures in the D.C. Circuit Court without stays in place. On February 19, 2025, the D.C. Circuit granted an EPA motion to hold the GHG case in abeyance for 60 days while the new EPA evaluates its position on the GHG rule. Similarly, on February 20, 2025, the D.C. Circuit granted an EPA motion to hold the MATS case in abeyance and removing the case from the upcoming oral argument calendar while the new EPA evaluates its position on the MATS rule. We cannot predict the full impact of the MATS and GHG rules on the operations of the coal-fired generation facilities operated by our customers; however, if the rules go into effect, the additional compliance costs could have a material adverse effect on our Coal Mining segment. The GHG standards are based on technologies such as carbon capture and sequestration/storage and natural gas co-firing. The compliance deadline for existing coal-fired, steam generating electric generating units (EGUs) planning to install carbon capture and sequestration/storage technology has been extended to January 1, 2032 for plants that intend to operate beyond 2039. If a coal-fired plant intends to close prior to 2032, no controls will be required and if a plant plans to close between 2032 and 2039, they must begin co-firing with natural gas by January 1, 2030. The MATS rules finalize changes for the filterable particulate matter surrogate emission standard for non-mercury metal hazardous air pollutants for existing coal-fired EGUs, the filterable particulate matter emission standard compliance demonstration requirements, and the mercury emission standard for lignite-fired EGUs. Review of the MATS rules indicate that the EPA significantly reduced the fine particulate matter emission standard for all existing coal-fired EGUs and will require continuous monitoring equipment to demonstrate compliance. Furthermore, the EPA elected to remove the lignite subcategory for mercury limits and will require lignite-fired EGUs to meet the same standard as other types of coal. The recent change in presidential administrations, recent executive actions, and the resulting changes at the EPA make it unclear whether the promulgated GHG or MATS Rules will be enforced, revised, or repealed. The various parties are working through the legal and administrative processes and the actual outcome remains unknown at this time. The CAA requires the EPA to review national ambient air quality standards (NAAQS) every
