 new sewage plant, and the rehabilitation of rail and port facilities, has elevated requirements for sediment control, water discharge, and biodiversity conservation. In tandem, AML has initiated a climate change risk assessment and is participating in the TNFD studies. On October 17, 2024, the National Solid Waste Management Policy was published by the Environmental Protection Agency. The Policy outlines the vision of the Government of Liberia, which recognizes that effective and efficient waste management is essential for the development of sound public health and improved quality of life. Mexico In March 2022, Mexico published a new standard on wastewater discharges, reducing the maximum permissible limits and introducing new parameters for quarterly monitoring and reporting to the National Water Commission (“CONAGUA”). ArcelorMittal internally defined a preliminary action plan to enhance wastewater quality discharges in line with the requirement of the standard through operational controls. In April 2023, with prior authorization from CONAGUA, ArcelorMittal submitted an action plan outlining milestones to bring wastewater discharge in compliance with the new standard. This program is scheduled to conclude in February 2027, with progress reports required to update on the program’s milestones. Additionally , due to the recent reform of the National Mining Regulation ("NMR"), several significant changes have been made, mostly related to environmental, water and waste management. With respect to water, the changes primarily relate to water access by the population (in preference to industrial use of water), which may have an impact on the ability to use water for iron ore transportation. Several constitutional claims against the NMR were submitted (including claims by ArcelorMittal Mexico). The final rulings are expected to be resolved by the Supreme Court in 2025. As part of these ongoing trends in water management, ArcelorMittal Mexico joined the initiative of a National Agreement on Water and signed the agreement on November 14, 2024, voluntarily assigning 56.5% of its concessioned volume to the National Water Commission for 2025. To fulfil its commitments under the Paris Agreement, the federal government of Mexico has published rules and principles for an
