<br />I <br />'- <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />.. <br />I <br />I <br />I <br />I <br />I <br />I <br />I. <br />I <br />I <br /> <br />Based on the aforementioned TDM examples, it is reasonable to expect that a long-term <br />commitment to coordinated application of TDM measures by Guidant could be successful <br />in reducing trips generated during the peak hours. <br /> <br />Transit <br /> <br />Metro Transit routes 224, 226 and 227 provide minimal transit service to the study area. <br />Routes 224, 226 and 227 serve the area in the morning (6:20 - 7:52 a.m.) and in the late <br />afternoon (3:30 - 6:00 p.m.). Service is limited and travels along Lexington Avenue. <br />These routes travel to and from Rosedale Shopping Mall transit center which is located <br />approximately five miles south of the campus. This transit center provides riders the <br />opportunity to transfer to several other routes to reach their residential area. <br /> <br />22. VEHICLE-RELATED AIR EMISSIONS <br /> <br />EAW: <br />PROVIDE AN ESTIMATE OF THE EFFECT OF TIlE PROJECT'S TRAFFIC <br />GENERATION ON AIR QUALITY, INCLUDING CARBON MONOXIDE LEVELS. <br />DISCUSS THE EFFECT OF TRAFFIC IMPROVEMENTS OR OTHER MITIGATION <br />MEASURES ON AIR QUALITY IMPACTS. (IF THE PROJECT INVOLVES 500 OR <br />MORE PARKING SPACES, CONSULT "EAW GUIDELINES" ABOUT WHETHER A <br />DETAILED AIR QUALITY ANALYSIS IS NEEDED) <br /> <br />AUAR: <br />The guidance provided in "EA W Guidelines should also he followed for an A UAR. <br />Mitigation proposed to eliminate any potential problems may be presented under <br />Item 21 and merely referenced here. The MPCA staff should he consulted regarding <br />possible ISP requirements for certain proposed developments; although the RGU may not <br />want to assume responsibility for applying for an ISP for specific developments, it may be <br />desirahle to coordinate the A UAR and ISP analyses elosely. <br /> <br />Motorized vehicles affect air quality by emitting airborne pollutants. Changes in traffic <br />volumes, travel patterns, and roadway locations affect air quality by changing the number <br />of vehicles in an area and altering traffic flow patterns. The effect of the development on <br />air quality was assessed by considering the changes in carbon monoxide, the primary <br />airborne pollutant that emitted from motorized vehicles. <br /> <br />Carbon Monoxide <br /> <br />Carbon monoxide (CO) is the traffic-related pollutant of most concern in the Twin Cities <br />Metropolitan Area. Concentrations of CO are generally highest at intersections with poor <br />levels of service and, consequently, more idling vehiclcs. Thc MPCA has established state <br />standards (or maximum pelmissible concentrations) for CO of 30 pmis per million (ppm) <br />for a I-hour period (average concentration), and 9 ppm for an 8-hour period. The MPCA <br />I-hour standard is more stringcnt than the fcdcral standard of35 ppm. <br /> <br />Thc Environmental Protection Agency (EP A) reclassillcd Minneapolis/St. Paul as an <br />attainment area for CO in 1999. The attainment status is contingent upon the <br />implementation of measures to assure that CO concentrations remain below standards.
