The data from the Stockton area monitoring sites are representative of the project site with the exception of that for carbon monoxide. Carbon monoxide is a localized ollutant, and problems with this pollutant are restricted to urbanized Stockton. concentrations near the project site are much lower than those measured at the Stockton monitoring sites. B. ENVIRONMENTAL IMPACTS ISSUE: Construction-related particulates Construction activities are a source of organic has emissions. Solvents in adhesives, non-waterbased paints, thinners, some insulating materials and caulking materials would evaporate into the atmosphere and would participate in the photochemical reaction that creates urban ozone. Asphalt used in paving is also a source of organic gases for a short time after its application. Construction dust could affect local air quality at various times during construction of the project. The dry,windy climate of tfie area during the summer months combined witfi the fine, silty soils of the region create a high potential for dust generation when and if underlying soils are exposed to the atmosphere. The effects of construction activities would be increased dustfall and locally elevated levels of PM-10 (Particulate Matter, 10 microns) downwind of construction activity. Construction dust has the potential for creating a nuisance at nearby properties. Significance: Potentially Significant. Mitigation: 10-1. Suspend dust-producing activities during periods of hi&h winds when dust control measures are unable to avoid visible dust plumes. 10-2. During the dry season (May-October) provide equipment and staffingg for watering all exposed or disturbed soil surfaces at_least twice daily, including weekends and holidays. An appropriate dust palliative or suppressant, added to water before application, should be utilized. 10-3. Require periodic clean-up of mud and dirt carried onto paved roads from the site Significance After Mitigation: Not Significant. UE: Project Effect on ISS ) Regional Air Quality The project is not expected to change emissions related to solid waste collection and disposal. While the Vehicle Miles Traveled and related emissions involved in the collection and disposal of solid waste will increase in future years as the population of the service area increases, the construction of the proposed project would not change 10-4
