The Tribal Minor New Source Review (NSR) program applies to new and modified minor sources and minor modifications at major sources in Indian Country. The program, established in a final rule the EPA issued on July 1, 2011, and codified at 40 CFR sections 49.151-49.161, is implemented through issuance of preconstruction permits that can include, among other requirements, pollutant emission limits for minor sources and emission limitations on the potential-to-emit of sources that would otherwise be considered major sources. This minor source program for Indian country is similar to state minor NSR programs. State minor NSR programs often use general permits and a few state programs allow permits by rule for similar emission units or stationary sources. A general permit or permit by rule may be written to address a single emissions unit, a group of the same type of emissions units, or an entire category of minor sources. General permits and permits by rule can offer a cost-effective means of issuing permits and provide a quicker and simpler alternative mechanism for permitting minor sources than a site-specific permitting process. This action establishes general permits and permits by rule. The action addresses permit coverage for the following source categories: hot mix asphalt plants; stone quarrying, crushing and screening facilities; gasoline dispensing facilities; petroleum dry cleaner facilities; and autobody repair and miscellaneous surface coating operations.
