2.0 ENVIRONMENTAL CHECKLIST Project construction would generate fugitive dusC3 (including particulate matter less than 10 microns in size or PMIO) and other criteria pollutants, primarily through excavation activities, construction equipment exhaust and haul truck trips, and related construction worker commute trips. The nearest sensitive receptors that could be potentially affected by construction generated fugitive dust in the vicinity of the construction Project would be the Garfield school located 0.3 miles away from the proposed pipeline segment along Monarch Bay Drive. Fugitive dust emissions would vary from day to day depending upon the level and type of construction activity, silt content of the excavated soil, and the prevailing weather. Measure AQ-1 provides for the preparation of a dust abatement program to minimize PM,o generation. Given the total amount of excavation required, along with the intensity of anticipated construction (six to nine months of construction to provide service to Monarch Bay Golf Complex, Marina Park/Par Course, and road medians; and approximately one year each to provide service to Oyster Bay Regional Park), daily combustion emissions from construction vehicles and construction-worker commute trips would not be significant or cumulatively considerable. Criteria pollutant emissions of reactive organic gases (ROG) and nitrogen oxides (N03) from these emission sources would incrementally add to regional atmospheric loading of ozone precursors during the construction period. BAAQMD Guidelines (BAAQMD, 1996) recognize that construction equipment emits ozone precursors, but indicate that such emissions are included in the emission inventory that is the basis for regional air quality plans, and that construction emissions are not expected to impede attainment or maintenance of ozone data in the Bay Area (BAAQMD, 1996). Consequently, the BAAQMD recommends determination of significance with respect to construction impacts be based not on quantification of emissions and comparison to thresholds, but upon inclusion of feasible control measures for PMIO as provided in Measure AQ-1. With respect to Project conformity with the federal Clean Air Act, the Project's potential emissions are below minimum thresholds and are well below 10 percent of the area's inventory specified for each criteria pollutant designated non-attainment or maintenance for the Bay Area. As such, further general conformity analysis is not required. e) Construction of the Project is not expected to generate odors. Operation of the project involves conveyance, treatment and distribution of recycled water which is also not expected to generate any objectionable odors. MITIGATION MEASURES Measure AQ-1: Prior to issuance of grading permits, the construction contractor shall submit to the City Engineer a dust abatement program, which shall include the following elements: Water all active construction areas at least twice daily, depending on type of operation, and wind exposure; Designate a person or persons to oversee the implementation of a comprehensive dust control program and to increase watering, as necessary; Construction grading activity should be discontinued in high wind conditions that cause excessive neighborhood dust problems, based on the discretion of the construction inspector; 3 "Fugitive" emissions generally refer to those emissions that are released to the atmosphere by some means other than through a stack or tailpipe.
