MOBILE6.2 Model run 20 August 2009. <br />The U.S. Environmental Protection Agency has designated all of Hennepin, Ramsey, <br />Anoka and portions of Carver, Scott, Dakota, Washington and Wright counties as a <br />maintenance area for carbon monoxide. The 171st Avenue AUAR study area is in <br />Sherburne County and thus not in the carbon monoxide maintenance area. <br />Furthermore, the EPA has approved a screening method to determine which <br />intersections need a hotspot analysis. A hot spot analysis is required if the <br />intersection is above the benchmark average annual daily traffic (AADT) threshold <br />of 79,400 or listed as one of the "Top Ten" intersections. All of the top ten <br />intersections are within the Twin Cities carbon monoxide maintenance area. Below <br />is a list of the top ten intersections and their 2007 AADT. <br />1.
