Initial Study and Negative Declaration watering of the site, cover all trucks hauling soil, sand, and other loose material, etc.) to control airborne particulates. All construction equipment is required to meet all current exhaust standards for emissions. These requirements will be made conditions of project approval. Overall, the proposed project would result in small, incremental, and insignificant increases in emissions. Therefore, these would be less-than- significant impacts. d. Project impacts related to increased health risk can occur either by introducing a new sensitive receptor, such as residences or a hospital, in proximity to an existing source of toxic air contaminants (TACs) or by introducing a new source of TACs with the potential to adversely affect existing sensitive receptors in the project vicinity. The BAAQMD recommends using a 1,000-foot screening radius around a project site for purposes of identifying community health risk for siting a new sensitive receptor or a new source of TACs. The proposed project includes converting the existing automobile service building to a convenience store and a drive-through carwash and constructing an addition to the proposed convenience store. The existing gas station would remain in approximately its existing condition. The proposed convenience store and drive-through carwash would not introduce new sensitive receptors (residences, hospital, etc.) to the project site. Occupants of residences are located within 1,000 feet of the project site. Typical operations of the convenience store and the drive-through carwash would not expose sensitive receptors in the vicinity to TACs. However, construction activities would temporarily generate TACs (e.g., construction equipment fueled by diesel which emits diesel particulate matter) that could affect sensitive receptors in the project vicinity. However, such emissions would be reduced to less than significant levels with the implementation of standard best practice construction management measures that would be required as conditions of project approval. As a result, the project would have a less-than-significant impact related to the exposure of sensitive receptors to air pollutants. e. Diesel exhaust fumes would be generated by equipment during demolition and construction. Diesel fumes would result in odors that may be perceptible to residents and tenants in the immediate vicinity of the project site. However, diesel odors would dissipate within a short distance from the project site. Therefore, diesel odor would not be expected to adversely impact the surrounding residents and tenants. Operations of the proposed project would not generate objectionable odors, because the project does not include any food preparation or processes, or other high odor- generating activities. The proposed convenience store would have 19
