 include air quality control, greenhouse gas ("GHG") emissions, water quality control, and management and disposal of solid and hazardous wastes.  Regulations in these major areas have become more stringent in recent years and have had a particular emphasis on climate change, renewable generation, and energy efficiency.TVA has incurred, and expects to continue to incur, substantial capital and operating and maintenance costs to comply with evolving environmental requirements primarily associated with, but not limited to, the operation of TVA's coal-fired and natural gas-fired generating units in general and emissions of pollutants from those units.  Failure to comply with environmental and safety requirements can result in enforcement actions and litigation, which can lead to the imposition of significant civil liability, including fines and penalties, criminal sanctions, and/or temporary or permanent closure of non-compliant facilities.  Historical non-compliance can also lead to difficulty in renewing existing permits, as well as difficulty in obtaining permits to bring new generation facilities online.  Other obstacles to renewal or permitting of new facilities include a proliferation of non-government organizations seeking to use litigation tools to drive up costs associated with, and delay or prevent permitting of, new fossil fuel facilities and related infrastructure in favor of renewable energy projects.Compliance with the Environmental Protection Agency's ("EPA") 2015 CCR Rule, as revised ("2015 CCR Rule") required implementation of a groundwater monitoring program, additional engineering, evaluation of authorized closure methods, coordination with certain state authorities, and ongoing analysis at each TVA CCR unit.  As further analyses are performed, including evaluation of monitoring results, there is the potential for additional costs for investigation and/or remediation.  In addition, on May 8, 2024, EPA published its Legacy CCR Rule, which expands the scope of the existing regulatory requirements of the 2015 CCR Rule to include two additional classes of CCR units: Legacy Surface Impoundments and Coal Combustion Residual Management Units.  As a result of the enactment of the final rule, during 2024, TVA recorded additional estimated AROs and recorded a corresponding regulatory asset due to AROs being associated with closed sites and asset retirement costs having been fully depreciated.  However, the amounts recorded are subject to various uncertainties, and actual amounts may differ materially based upon a number of factors, including, but not limited to, the outcome of legal challenges to the Legacy CCR Rule, ongoing evaluations of the number and scope of newly regulated units, determinations on final closure requirements and performance standards
