R18-2-515. Minor NSR in General Permits

A. A general permit may include emission standards designed to assure that a stationary source covered by the permit will comply with minor new source review under R18-2-334(C). The emission standards may consist of any combination of the following: 1. Limits designed to assure that emissions from a stationary source that is a member of the class of facilities covered by the permit will not interfere with attainment or maintenance of a NAAQS. 2. Limits imposing reasonably available control technology. B. Except as provided in subsection (C), if a general permit includes emission standards under subsection (A), then any stationary source that is a member of the class of facilities covered by the permit or any minor NSR modification to such a source may comply with R18-2-334 by obtaining coverage under the permit. C. An owner or operator seeking coverage under a general permit in order to obtain authorization to construct or make a minor NSR modification to a stationary source shall instead apply for an individual permit, if the Department determines there is reason to believe the source or modification could interfere with attainment or maintenance of any national ambient air quality standard. In making this determination, the Department: 1. Shall consider the factors in R18-2-334(E)(1) to (6). 2. Shall consider whether the dispersion characteristics of the source are likely to result in higher ambient concentrations of a conventional pollutant than the modeling assumptions used to establish an emission standard under subsection (A)(1). 3. May apply a screening model to the source’s emissions.
