The original CAA list of regulated air toxics included 189 pollutants. Since 1990, EPA has modified the list through rulemaking to include 187 pollutants. Air toxics are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. The CAA allows any person to petition EPA to modify the list by adding or deleting a substance. To add a substance, the petition must provide adequate data for EPA to determine that emissions, ambient concentrations, bioaccumulation, or deposition of the substance are known to cause or may reasonably be anticipated to cause adverse effects to human health or the environment.

EPA received petitions requesting 1-bromopropane (1-BP), also known as n-propyl bromide (nPB), be added to the CAA list of air toxics. This chemical is a solvent used in electronics and metal cleaning, surface coatings, dry cleaning, adhesives, and as an intermediate chemical in the manufacture of pharmaceuticals and agricultural products. On June 18, 2020, EPA finalized its decision to grant petitions to add 1-BP to the list of CAA hazardous air pollutants ― this is the first time since 1990 that EPA has granted a petition to add a hazardous air pollutant to the CAA. Granting these petitions is the first step in a series of actions to address air emissions of 1-BP. In a subsequent action, EPA will modify the Code of Federal Regulations to add 1-BP to the CAA list of air toxics ―  after it is added, EPA may consider revising or creating new emissions standards for source categories that emit 1-BP.

The purpose of this webinar is to provide a high-level overview of the petition approval process and to provide small businesses an opportunity to ask questions or provide feedback concerning facilities in their community that may be subject to revised or new emission standards by the upcoming listing.  For more information on 1-BP, refer to
