The Environmental Protection Agency has added a new chemical to the list of Hazardous Air Pollutants (HAPs) for the first time since the list was created in 1990. The chemical, 1 bromopropane (1-BP), is used as a commercial degreaser and in dry cleaning operations. Now that 1-BP is added to the list of HAPs, the EPA will begin the process of proposing final regulations governing emission limitations which could take several years. Companies emitting 1-BP should begin the process of accessing their emission potentials, and to consider alternative products to eliminate the use of 1-BP altogether. Specifically, facilities that are not major sources for HAPs should consider whether their 1-BP emissions would put them over the threshold for being a major source of HAPs subject to the stringent, major source permitting under the Clean Air Act.
