Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is required to evaluate and control emissions of hazardous air pollutants (HAPs). The original list of HAPs included 189 pollutants which was later modified through various rulemakings to include 187 HAPs.
On June 18, 2020 EPA took steps to add the chemical 1-bromopropane (1-BP), also known as n-propyl bromide (nPB), to the CAA HAP list after having received petitions to do so.
N-propyl bromide is commonly used as a solvent in a wide array of processes and products including manufacturing operations, dry cleaning, spray adhesive or surface coating applications, agricultural and pharmaceutical products, oven cleaning and degreasing products, and metal and electronic cleaning products.
Through EPA's evaluation and technical review of the petitions, EPA concluded that nPB is reasonably anticipated to cause adverse effects to human health and the environment.
On Wednesday, July 29th 2020 EPA held a webinar 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 or operations that may be subject to revised or new emission standards by the upcoming listing.
EPA seeks information from any small businesses that may use, sell, manufactures or distributes nPB. If you are a small business that would like to provide feedback on this issue, please contact EMAP at email@example.com to discuss further.
