Relating to authorizing the Department of Environmental Protection to promulgate a legislative rule relating to alternative emission limitations during startup and shutdown operations.

HB 4205 authorizes West Virginia's Department of Environmental Protection (DEP) to implement a specific rule (45 CSR 01) governing emission limits for industrial facilities during startup and shutdown operations. This rule directly affects power plants and manufacturing facilities that temporarily exceed standard emission levels when starting up or shutting down equipment. The key provision allows the DEP to establish alternative, temporary emission limits during these operational phases, rather than requiring strict adherence to regular standards. The bill formally approves a rule already filed with the State Register on July 22, 2025, making it effective without additional legislative action.
