mY~~A ANA Re~o.~esto E nvi ran mental;""iCheekl ist - .- ....,:.,. .' ,>-~.. .;:-, For CEQA .c~'rJ~liance Short-term Constructed Related Air Quality Impacts Construction operations associated with the proposed project could potentially result in short-term increases in particulate matter, and to a lesser degree increases in carbon monoxide and ozone. Peak day construction emissions for most pollutants arising from construction of the proposed project would occur during the grading and demolition phases. Using the South Coast Air Quality Management District CEQA Air Quality Handbook as a general guideline, the threshold for potentially significant short-term air quality impacts would involve the grading of 1,309,000 square feet of area and the demolition of 23,214,000 cubic feet of building area. The proposed project would require the demolition of approximately 100,000 cubic feet of building area and re-grading of 52,000 square feet of lot area only The amount of grading and demolishing activities for the proposed project would be considerably less than the threshold of significance outlined in the CEQA Air Quality Handbook. While the construction related emissions associated with the proposed project would not exceed the thresholds established by the SCAQMD, the emissions could be a nuisance to other existing land uses in the nearby vicinity of the project site. To minimize short-term construction related air impacts within the project area the following project enhancement measure shall be implemented. Project Enhancement Measure During construction, the contractor would be required to comply with SCAQMD Fugitive Dust Rule 403 to suppress dust generated by construction operations. To ensure compliance with SCAQMD Fugitive Dust Rule 403, grading plans and demolition plans for the proposed project shall reflect the following notes: 1. All material excavated or graded will be sufficiently watered to prevent excessive amounts of dust. 2. All clearing and earthwork activities shall cease during period of high winds (winds greater than 25 mph averaged over one hour) or during Stage 1 or Stage 2 smog episodes. 3. Streets surrounding the project site shall be cleaned at the end of each day of construction. 4. All material transported offsite shall either be sufficiently watered or securely covered to prevent excessive amounts of dust. 5. The amount of area disturbed by clearing and earthwork activities shall be minimized at all times. 6. Equipment engines shall be maintained in good condition and in proper tune according to manufacturer's specifications. 7. To the extent feasible, gasoline powered equipment shall be used for onsite and offsite construction activities. In addition, it has been determined that implementation of the proposed project would not result significant long-term or short-term air quality impacts. Therefore, the proposed project area would not be exposed to substantial concentrations of air quality pollutants. Finally, the proposed project is a retail land use and would not generate significant long-term operational odors. Construction equipment and operations associated with the proposed project could potentially result in odor impacts. However, the odors would be short-term and would not be considered significant. 31AT31 3
