Cripple Creek & Victor Gold Mining Company MLE Traffic Impact Study Truck Deliveries of Operating Supplies For this study, actual truck or large vehicle (see definition in previous section) counts were taken to see how much of the mine-related traffic is attributable to large vehicles or truck deliveries. This was determined by counting the number of large vehicles (anything larger than a pickup truck) turning into and out of the mine at the Carlton and Ironclad access points. Figure 2 shows the 14-hour turning movement count with truck volumes shown in parentheses. As indicated previously, it is estimated that most of the trucks making deliveries to the mine are doing so during these hours (5:30 A.M. to 7: 30 P.M.). As indicated in the figure, the volume of trucks entering and exiting the mine during the 5:30 A.M. to 7:30 P.M. time period is relatively balanced. At the Ironclad mine access, approximately 14 trucks are making round trips (entering trip and exiting trip) related to the mine. At the Carlton access, approximately 20 trucks are making round trip deliveries into and out of the mine.

CC&V has provided a table of projected truck deliveries based on the 25 million ore tons operating scenario. A summary of these deliveries is shown in Table 1. The numbers are given in a rate of truck deliveries per year and then broken down into monthly and daily truck delivery rates. They are estimated based on the amount of supplies needed each year to mine 25 million tons of ore and the capacity of each truck to carry the various supplies to the mine. The "trucks/day" column is the average daily truck deliveries. The "potential" column shows a "worst case" scenario for daily truck deliveries of each truck delivery type. Each "potential" delivery number is obtained by rounding each of the delivery numbers in the "trucks/day" column up to the nearest whole number. This table indicates that under the average scenario, it is estimated that a total of 5 trucks make deliveries to the Ironclad mine access each day while a total of 23 trucks make deliveries to the Carlton security gate. Under the worst case scenario, it is estimated that a total of approximately 17 trucks make deliveries to the Ironclad mine access while a , Interstate Engineering, Inc. 5 April, 2008
