→ Adding n-propyl bromide to list of hazardous air pollutants

Comments Close:

The comment period has been extended on the Environmental Protection Agency’s draft notice of the rationale for granting petitions to add n-propyl bromide (nPB), also known as 1-bromopropane (1-BP), (Chemical Abstract Service No. 106-94-5) to the list of hazardous air pollutants to the Clean Air Act. The Halogenated Solvents Industry Alliance and New York State Department of Environmental Conservation submitted petitions requesting that nPB be added to the list of hazardous air pollutants. Based on the EPA's evaluation of the petitioners' showing concerning potential hazards, emissions, and atmospheric dispersion modeling that provided estimates of ambient concentrations of nPB, the EPA has determined that there is adequate evidence to support a determination that emissions and ambient concentrations of nPB may reasonably be anticipated to cause adverse health effects. This draft notice contains a written explanation of the decision to grant the petition. Petitions and other supporting documents can be found in the docket folder.

 

*As of Tuesday, June 6, 2017, the EPA granted a full extension of the comment period from the June 8, 2017 deadline (an interim extension) to October 1, 2017, in order to allow for the review of data and information that would otherwise become available after the close of the comment period.
