Would <br />the project: <br />a) Conflict with or obstruct implementation of the ^ ^ ~ ^ <br />applicable air quality plan? <br />b) Violate any air quality standard or contribute ^ ^ ^X ^ <br />substantially to an existing or projected air quality <br />violation? <br />c) Result in a cumulatively considerable net increase ^ ^ ^X ^ <br />of any criteria pollutant for which the project <br />region is non- attainment under an applicable <br />federal or state ambient air quality standard <br />(including releasing emissions which exceed <br />quantitative thresholds for ozone precursors)? <br />d) Expose sensitive receptors to substantial pollutant ^ ^ ^X ^ <br />concentrations? <br />e) Create objectionable odors affecting a substantial ^ ^ ^X ^ <br />number of people? <br />Discussion <br />a-c) The proposed project is expected to generate short-term impacts related to construction <br />activities (e.g., clearing grubbing, site grading, etc.). Construction activity on the site is <br />required to implement dust control measures (e.g., periodic watering of the site, cover all <br />trucks hauling soil, sand, and other loose material, etc.) to control airborne particulate. <br />All construction equipment is required to meet all current exhaust standards for <br />emissions. These requirements will be made as conditions of the project approval. <br />Long-term operational emissions would be generated by both stationary and mobile <br />sources as a result of normal day-to-day activities on site subsequent to construction <br />completion. Stationary area source emission would be generated by space (HVAC) and <br />water heating devices and operation of landscape maintenance equipment. Mobile source <br />emissions would be generated by motor vehicles traveling to and from the project site. <br />According to the project traffic studyZ, the project would generate approximately 587 <br />11 <br />
