L <br /> Based on available data,the emission factor for unpaved roads is 0.568 pounds of PM 10 per <br /> vehicle mile traveled(uncontrolled)and 0.456 pounds of PM 10 per vehicle mile traveled <br /> (controlled). To account for emission controls, a control efficiency of 75% was applied. Weather <br /> data(days of measurable precipitation)from http://www.wrcc.dri.edu/summary for Lodi, <br /> California. The project condition provides for 981 and 256,041 (see Transportation and Traffic <br /> section)daily and annual round-trip vehicle trips,respectively, each presumed to be traveling a <br /> distance of r/2 mile on unpaved roads and within the circulation area(per trip). <br /> Nonroad Equipment and Mobile Vehicles <br /> k The types of nonroad equipment at the project site include loaders,grader, excavators, off- <br /> highway trucks (such as water trucks), scrapers,and haul trucks.Emission factors for all <br /> equipment except haul trucks and pickup trucks were obtained from the U.S. EPA's NONROAD <br /> model and documentation and databases prepared in support of NONROAD. The NONOAD <br /> 6' model considers the rules of 40 CFR Part 89 that establish standards for emissions of CO,VOC, <br /> NOx, and PM on equipment of the type used in the construction and other industries. Emission <br /> factors for each equipment type were applied to the anticipated equipment work output <br /> (horsepower-hours of expected equipment use). Average horsepower,hours of operations, and <br /> Lload factors were developed based on NONROAD databases, specifically for California. <br /> Emission factors for haul trucks were obtained from the EMFAC2002 model. Haul trucks with a <br /> i <br /> gross vehicle weight greater than 8,500 pounds (heavy trucks). The pickup trucks were <br /> conservatively assumed to travel 50 miles each day, although they are mainly used for inspection <br /> and supply/personnel transport purposes at the site. The haul trucks were assumed to travel 50 <br /> miles each way between the facility and the aggregate markets, a conservative estimate given the <br /> distance between the project site and typical markets. Table AQ-5 presents the nonroad usage <br /> data. Table A-6 and Table A-7 present the emission factors used of nonroad equipment and <br /> SIP motor vehicles for 2007 and 2021,respectively. <br /> I <br /> r <br /> L. <br /> w <br /> F <br /> f. <br />
