Relating to authorizing the Department of Environmental Protection to promulgate a promulgate a legislative rule relating to cross-state air pollution to control annual nitrogen oxides emissions, annual sulfur dioxide emissions, and ozone season nitrogen oxides emissions.

HB 4211 authorizes West Virginia's Department of Environmental Protection (DEP) to implement existing rules controlling cross-state air pollution. It specifically targets annual emissions of nitrogen oxides, sulfur dioxide, and nitrogen oxides during ozone season, which directly affects power plants, industrial facilities, and other major polluters within the state. The bill formalizes the DEP's authority under existing law to enforce these emission limits as outlined in the previously filed "45 CSR 43" rule. This creates a clear regulatory framework for managing pollution that crosses state lines, without establishing new emission caps.
