Granting Petitions To Add n-Propyl Bromide to the List of Hazardous Air Pollutants

On January 9, 2017, the Environmental Protection Agency (EPA) published a 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 contained in section 112(b)(1) of the Clean Air Act. In this notice, the EPA is extending the comment period on the draft notice until October 1, 2017. The EPA received a timely request to extend the comment period from March 10, 2017, 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. On March 6, 2017, as an initial response, the EPA made an interim extension of the comment period by 90 days until June 8, 2017. The EPA is now granting the request in full and extending the comment period until October 1, 2017.
