Eliminating preferential treatment related to a coal-fired electric generating plant.

SB 6172 eliminates special exemptions for coal-fired power plants in Washington State's emissions reporting system. It removes preferential treatment by requiring coal plants to follow the same reporting rules as other large emitters (those exceeding 25,000 metric tons of CO2 equivalent annually), repealing prior provisions that created separate standards. The bill amends Washington’s emissions law (RCW 70A.65.080) to apply consistent reporting thresholds to all covered entities, including coal plants, waste-to-energy facilities, and railroads. This change ensures coal plants are subject to the same compliance requirements as other major emitters without special exemptions. The policy directly affects coal-fired power plants and other large emitters that previously operated under different rules.
