Utah Admin. Code R307-410-4 - Modeling of Criteria Pollutant Impacts in Attainment Areas

Prior to receiving an approval order under Rule R307-401, a new source in an attainment area with a total controlled emission rate per pollutant greater than or equal to amounts specified in Table 1, or a modification to an existing source located in an attainment area which increases the total controlled emission rate per pollutant of the source in an amount greater than or equal to those specified in Table 1, shall conduct air quality modeling, as identified in Section R307-410-3, to estimate the impact of the new or modified source on air quality unless previously performed air quality modeling for the source indicates that the addition of the proposed emissions increase would not violate a National Ambient Air Quality Standard, as determined by the director.

TABLE 1

POLLUTANT	EMISSIONS
sulfur dioxide	40 tons per year
oxides of nitrogen	40 tons per year
PM10 - fugitive emissions and fugitive dust	5 tons per year
PM10 - non-fugitive emissions	15 tons per year
PM2.5 - combined non-fugitive emissions, fugitive dust, and fugitive emissions	10 tons per year
carbon monoxide	100 tons per year
lead	0.6 tons per year
