AMERICAN ELECTRIC POWER CO INC

The Federal Mine Safety and Health Act of 1977 (Mine Act) imposes stringent health and safety standards on various mining operations. The Mine Act and its related regulations affect numerous aspects of mining operations, including training of mine personnel, mining procedures, equipment used in mine emergency procedures, mine plans and other matters. Prior to October 1, 2023, SWEPCo, through its ownership of DHLC, a wholly-owned lignite mining subsidiary of SWEPCo, was subject to the provisions of the Mine Act. Effective as of October 1, 2023, the U.S. Department of Labor’s Mine Safety and Health Administration put DHLC in Abandoned Mine Status. As a result of this designation, DHLC is no longer subject to the Mine Act or Section 1503 of The Dodd-Frank Wall Street Reform and Consumer Protection Act.
