'l6h1 TABLE 5-8 PREDICTED CARBON MONOXIDE (CO) CONCENTRATIONS (PPM) RECEPTOR I.HOUR AVERAGE 8-HOUR AVERAGE Rl 3.8 2.8 R2 4.9 3.6 R3 5.0 3.6 R4 4.0 2.9 R5 3.6 2.7 R6 2.8 2.1 STANDARD 30.0 9.0 As shown in the table, all of the predicted CO concentrations are well below the state air quality standards. Therefore, development of the proposed project will have no significant impact on air quality. Alternative Proiect - Business Park The business park uses may generate emissions from heating equipment or industrial processes, Emissions from these potential sources are dependant on the fuel used, type of equipment and type of industrial process. If facilities are proposed that require air emissions permits, permits will be obtained prior to construction, Traffic air quality impacts of the alternative business park development would be similar to the proposed project. 5.2.3 Mitigation Measures No-Build Alternative The no build alternative will have no significant impact on air quality. Proposed Proiect - Mixed-Use Development The proposed project will have no significant impact on air quality so no mitigation is required. Alternative Project - Business Park The alternative project will have no significant impact on air quality so no mitigation is required. 5.3 NOISE 5.3.1 Affected Environment . fI I I I I I I I ~ I I I I I Noise is generally defined simply as unwanted sound. Various factors affect how sound is perceived . by the human ear. These factors include the loudness of the sound, the frequency, the exposure WISP ARK Rice Creek Corporale Park DraftEIS December 10, 1998 Page 80
