The ETDM Programming Screen (ETDM #8001) performed in 2007 for this project concluded that Air Quality be identified with a summary degree of effect of Minimal. The preferred alternative was subjected to a carbon monoxide (CO) screening model that makes various conservative worst-case assumptions related to site conditions, meteorology and traffic. The Florida Department of Transportation’s (FDOT’s) screening model, CO Florida 2004 (released September 7, 2004) uses the latest United States Environmental Protection Agency (USEPA) approved software (MOBILE6 and CAL3QHC) to produce estimates of one-hour and eight-hour CO levels at default air quality receptor locations. The one-hour and eight-hour estimates can be directly compared to the one and eight hour National Ambient Air Quality Standards (NAAQS) for CO that are 35 parts per million (ppm) and 9 ppm, respectively. The Big Bend Road Interchange is forecasted to have the highest total traffic volumes around the receptors adjacent to the merge/diverge areas with Big Bend Road, while Gibsonton Drive is forecasted to have the highest total traffic volumes around the receptors adjacent to the merge/diverge areas with I-75. For purposes of this screening both interchanges were subjected to a CO Screening assuming a diamond interchange within CO Florida 2004. The Build and No-Build scenarios for the design year (2035) were evaluated using PM peak hour volumes. Estimates of CO were predicted for receptors with distances from the edge of roadway as identified on the baseplans for the no-build and build scenarios. These distances were entered into the model as the minimum distances from the edge of pavement to the right-of-way lines for the arterial roadway along with the on/off ramps. Graphics depicting these distances are attached to this memorandum. Based on the results from the screening model, the highest project-related CO one and eight hour levels are not predicted to meet or exceed the one or eight hour NAAQS for this pollutant with either the Build or No- Build alternatives. As such, the project “passes ” the screening model test. The results of the screening model test, along with the traffic data used in the analysis, are attached to this memorandum. “The project is located in an area which is designated attainment for all of the National Ambient Air Quality Standards under the criteria provided in the Clean Air Act. Therefore, the Clean Air Act conformity requirements do not apply to the project.”

AIR QUALITY SCREENING TEST Date: November 2, 2009 Subject: FDOT WPI Segment Number: 419235-2 Interstate 75 (I-75) PD&E Study, Moccasin Wallow Road to South of US 301 Manatee and Hillsborough Counties, FL The referenced proposed project is located in Manatee and Hillsborough Counties, FL, an area currently designated as being attainment for the following criteria air pollutants: nitrogen dioxide, particulate matter (2.5 microns in size and 10 microns in size), sulfur dioxide, carbon monoxide, lead and ozone.
