With improvements to CR J and no access to CR I, approximately 80 percent of the site development could be accommodated. 1.4.8 Air Quality The residential units associated with the proposed project could generate particulate (wood smoke) emissions and odors if they are equipped with fireplaces, 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 obtainedcprior to construction. The impacts of the proposed project on air quality were evaluated by modeling future traffic flow and vehicle emissions at intersections in the vicinity of the project to estimate CO concentrations with project generated traffic. Analysis was conducted of both the CR I and CR J interchanges with 1-35W. These interchange areas will experience the highest traffic volumes in the vicinity of the project and will therefore have the highest CO concentrations. Receptor sites were selected in the vicinity of each interchange to represent locations where people may be present for time periods consistent with air quality standards. The analysis yielded a maximum one-hour average CO concentration of 5.0 PPM relative to a standard of30 PPM. The maximum forecast eight-hour average CO concentration was 3,6 PPM relative to a standard of 9 PPM. Therefore no significant air quality impacts are expected. 1.4.9 Noise The existing environment in the vicinity of the proposed project is subject to noise from motor vehicles. The primary source of vehicular noise in the study area is traffic on 1-35W because of the large volume of traffic on the freeway, the speed of the traffic and the high percentage of trucks in the traffic mix. The proposed project will generate additional traffic which will add to existing traffic noise levels along streets serving the project. Noise sensitive receivers in the vicinity of the project that could be affected by traffic noise include the following: . Residential development on the north side of CR I east of Rice Creek. Residences are generally approximately 100 feet from the roadway centerline. . Residential development on the north side of CR Iwest of 1-35W. Residences are generally approximately 100 feet from the roadway centerline. . Residential development proposed as part of the Rice Creek development project. The nearest residential units are approximately 650 feet from the centerline ofI-35W. Noise impacts in these areas were estimated for the PM peak traffic hour. All of the predicted noise levels were below the state daytime residential noise standards. The project generated traffic adds a maximum of 2 dBA to traffic noise levels along CR 1 The residential development proposed as WISPARK Rice Creek Corporate Park Draft EIS December 10, 1998 Page 7
