Environmental Protection Agency 40 CFR Part 49 [EPA-HQ-OAR-2003-0076; FRL-9818-8] RIN 2060-AR25 AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. SUMMARY: The EPA is proposing three changes to the New Source Review (NSR) program for minor sources and minor modifications at major sources in Indian country, which we refer to as the “Tribal minor NSR program.” First, we propose to expand the list of emissions units and activities that are exempt from the Tribal minor NSR program by adding several types of low-emitting units and activities. Second, we propose to more clearly define the term “commence construction” and add the term “begin construction” to better reflect the regulatory requirements associated with construction activities. We believe both of these proposed changes would simplify the program, resulting in less burdensome implementation without detriment to air quality in Indian country. Lastly, we are reconsidering the advance notification period for relocation of a true minor source in response to a petition received on the final Tribal NSR rule from the American Petroleum Institute, the Independent Petroleum Association of America and America's Natural Gas Alliance. DATES: Comments must be received on or before August 5, 2013. Public Hearing. If anyone contacts us requesting to speak at a public hearing by June 25, 2013, we will hold a public hearing. Additional information about the hearing will be published …
