Typical of most developments, the proposed development will generate air pollution as a result of increased motor vehicle activity. Motor vehicles emit a variety of air pollutants including carbon monoxide (CO), hydrocarbons, nitrogen oxides, and particulates. The primary pollutant of concern is CO, which is a byproduct of the combustion process of motor vehicles. CO concentrations are highest where vehicles idle for extended periods of time. For this reason, CO concentrations are generally highest in the vicinity of signalized intersections where vehicles are delayed and emitting CO. Generally, concentrations approaching state air quality standards are found within about 100 feet of a roadway source. Further from the road, the CO in the air is dispersed by the wind such that concentrations rapidly decrease. The Indirect Source Permit (ISP) rule 7023.9010 was terminated in 2001; therefore, an ISP is not required for the proposed development. A hot spot air quality screening was conducted and is described below. The EPA has approved a screening method to determine which intersections need analysis for potential hot spot air quality impacts. The screening analysis consists of two criteria. If either criterion is met, then an intersection analysis would be required. The first criterion is to determine whether the total daily approach volume of the AUAR study area exceeds 79,400 AADT. If it does, then an analysis would be required. The approach volumes at all of the signalized intersections near the AUAR study area are below approximately 40,000 AADT, with the highest being at the intersection of Lexington Avenue and CR 96, and all are well below the threshold of 79,400. Therefore, the first criterion is not met. The second criterion compares the AUAR study area to the locations of 10 intersections that the MPCA has identified as having the highest volumes in the metro area. If any of these 10 intersections were affected by either development scenario then analysis would be required. The nearest of these intersections is five miles away, at the intersection of TH 252 and 66 Street in Brooklyn Center, and would not be impacted by th the development; therefore, the second criterion is not met. As a result, no hot spot analysis is needed, and no measurable change in air quality is anticipated under either of the development scenarios. No air quality mitigation is required. c.D-D,,,, UST AND ODORS ESCRIBE SOURCES CHARACTERISTICS DURATION QUANTITIES AND INTENSITY OF .(F DUST AND ODORS GENERATED DURING PROJECT CONSTRUCTION AND OPERATION UGITIVE DUST MAY BE 16).D DISCUSSED UNDER ITEM A ISCUSS THE EFFECT OF DUST AND ODORS IN THE VICINITY OF THE PROJECT .I INCLUDING NEARBY SENSITIVE RECEPTORS AND QUALITY OF LIFE DENTIFY MEASURES THAT WILL BE TAKEN .
