On June 11, 2021, the US Environmental Protection Agency (EPA) issued an Advanced Notice of Proposed Rulemaking as a next step before adding of 1-Bromopropane (1-BP) to the Clean Act Act’s list of Hazardous Air Pollutants (HAP). EPA intends to add 1-BP to the HAP list by the end of 2021. More information is available in the US EPA fact sheet on this proposal.
1-BP is commonly used in degreasing operations for cleaning metals, plastics and electronic, and optical components; adhesive spray applications; dry cleaning; and solvent sprays used in operations like asphalt production, aircraft maintenance, and synthetic fiber manufacturing, and aerospace manufacturing.
EPA is soliciting data and information on 1-BP usage, emission controls, and associated costs to ensure that the regulatory infrastructure is in place to control the emissions of 1-BP effectively and efficiently. After 1-BP is added to the list, EPA must promulgate standards to address emissions of 1-BP. If your facility uses 1-BP, now is the time to provide any data or information.
