4.5 AIR QUALITY <br /> equipn:,:.nt. Annual emission rates for residential uses were taken from published sources (Bay Area Air <br /> Quality Management District, 1985). <br /> Emissions associated with project vehicles and residential sources of pollutants are well below the <br /> thresholds of significance recommendedby the San Joaquin Valley Unified Air Pollution Control District- <br /> San Joaquin Unit, and this impact is, therefore, considered less than significant. <br /> Mitigation <br /> 4.5-2 The impact of residential fireplace emissions of PM-10 and carbon monoxide to air <br /> quality can be reduced by restricting the number of fireplaces in residences to one per <br /> unit, or requiring residential use of EPA-certified woodstoves or fireplace inserts. <br /> Impact <br /> 4.5-3 The project would increase the potential for air quality and odor-related land use <br /> conflicts between residences and agricultural uses. <br /> The proposed project would pi ace urban land uses in proximity existing agricultural lands, increasing the <br /> potential for air quality-related land use conflicts. Conflicts between new residential uses and existing <br /> agricultural uses have been increasingly reported from recently urbanized areas within the Sacramento <br /> and San Joaquin valleys. Tilling, waste burning and pesticide application are typical agricultural <br /> activities that can elicit complaints from nearby residences. <br /> The lot locations within the site provide substantial setbacks from surrounding agricultural uses. Also, <br /> the agricultural activities upwind(west) of the site are irrigated pasture lands, which involve few of the <br /> activities known to elicit complaints. For these reasons, the potential for land use conflicts appears low <br /> and this impact is considered less than significant. <br /> Mitigation <br /> 4.5-3 No mitigation measure is required or recommended. <br /> 4.5-10 <br />
