PM10) emissions from construction activities at the site were calculate using an emission factor of 0.3 ton/acre-month and the 19.8 ac construction area. The 0.3 ton/acre-month emission factor assumes th an effective watering program to suppress dust emissions would be imple- mented. Vehicular traffic to and from the project site during project construction was estimated assuming that each of the anticipated 30 work- ers would travel one 25 mile round-trip each working day. Emission factors corresponding to an average speed of 30 miles per hour (mph) fo the year 1990 (BAAQMD, 1985) were used to estimate the emissions fro construction worker vehicles. The total emissions from construction activity are presented in Table 3.9. Mitigation Measure. Fugitive dust emissions would be mitigate through the implementation of an effective watering program. Thi program would require the application of water to exposed surfaces a minimum of once daily during dry weather conditions. The emissions from construction activities would be temporary and generally of shot duration. With the use of an effective watering program, emissions fro construction-related activities would not be significant. Impact 2 - Emissions from Vehicular Traffic Vehicular traffic would increase in the vicinity of the proposed project site. Diesel truck traffic related to facility operation as well as vehicles driven to and from the site by employees would contribute to emission increases. Based on 80 percent plant availability and normal daylight delivery time periods of 12 hours per day, 5 days per week, the expected number of trucks entering and exiting the facility would be as follows: Biomass: 3 to 5 trucks/hour Briquettes: 3 to 4 trucks/hour Used Lubricant: 1 truck every 4 hours Finished Oil : 1 truck every 4 to 7 hours Distillate: 1 truck every 2 days Filtrate/Sludge Removal : 1 truck per month TOTAL: 7 to 9 trucks/hour 3-59 101-30.R5 4/13/89
