EPA Proposal on Air Rule; Applicability for Operations with HAPs

Updated: Oct 5, 2023

On July 25, 2023, the U.S. Environmental Protection Agency (EPA) proposed updates to the Air Emissions Reporting Requirements rule to include reporting of hazardous air pollutants (HAPs), or "air toxics”. The proposed rule would require approximately 130,000 facilities to report air toxics emissions data directly to the EPA.

This proposed rule-making may be relevant to manufacturing operations that utilize one or more materials containing HAPs. Here are some examples:

  • Coatings or inks containing xylene, ethylbenzene, toluene, or other HAP

  • Flavors or fragrances containing glycol ethers

  • Sealants or adhesives containing diisocyanates, n-methyl-2-pyrrolidone, toluene diisocyanate, or other HAP

  • Vitamin powders containing zinc, selenium, manganese, copper, or chromium compounds

  • Specialty chemicals containing methanol, formaldehyde, 1,2,4-Trimethylbenzene, nitrate compounds, or other HAP

  • Mortars containing lithium carbonate

  • Specialty metals containing lead (Pb), chromium (Cr), cadmium (Cd), cobalt (Co), nickel (NI), beryllium (Be), or other HAP

EPA will host webinars and hearings to encourage public feedback. For the full proposal, visit: Air Emissions Reporting Requirements Proposal.
