In that action, the Environmental Protection Agency (EPA) proposed hazardous air pollutant (HAP) emissions standards for the following pollutants: hydrogen chloride (HCl), mercury, total hydrocarbon (THC) as a surrogate for organic HAP, and dioxin/furans (D/F). The EPA is proposing revisions to the proposed emission limits for HCl, mercury, organic HAP, and D/F based on additional information gathered since the publication of the January 5, 2023, proposed rule amendments. We solicit comments on all aspects of this proposed action. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> Comments must be received on or before March 11, 2024.
