Truck loading frequency on an hourly basis was estimated by reviewing current hourly truck count <br /> information collected in May 2004 on Bird Road south of SR-132 and on recent information provided by <br /> individual quarry operators. Truck loading frequency information provided by individual quarry <br /> operators represented their best estimate of what their individual loading frequency would be by hour of a <br /> typical day. The estimated year 2007 daily truck loading frequencies are shown in Table 12. The AM <br /> and PM peak hours were previously identified to include 6:00 to 7:00 a.m. (AM peak hour) and 4:00 to <br /> 5:00 p.m. (PM peak hour). As shown in Table 12,these two hours would have 250 and 60 two-way truck <br /> ►w trips respectively that would be entering and exiting SR-132. <br /> - TABLE 12 <br /> VERNALIS AREA AGGREGATE PRODUCTION SITES <br /> YEAR 2007 BASE HOURLY TRUCK LOADING FREQUENCIES AND <br /> ESTIMATED HOURLY TRUCK GENERATION <br /> AM PERIOD <br /> Daily 12:00 1:00 2:00 3:00 4:00 5:00 <br /> Total 2-W ay 1:00 2:00 3:00 4:00 5:00 6:00 <br /> 2,509 1 7 6 6 20 61 153 <br /> y % of Daily 1 0.3% 0.2% 0.2% 0.8% 2.4% 6.1% <br /> AM PERIOD <br /> Daily 6:00 7:00 8:00 9:00 10:00 11:00 <br /> Total 2-W ay 7:00 8:00 9:00 10:00 11:00 12:00 <br /> ■,. <br /> 2,508 250 252 242 229 236 195 <br /> % of Daily 10.0% 10.0% 9.7% 9.1% 9.4% 7.8% <br /> PM PERIOD <br /> Daily 12:00 1:00 2:00 3:00 4:00 5:00 <br /> �.
