This site is the future location of <br />an aggregate extraction operation to include bituminous pavement, aggregate base, and <br />miscellaneous materials production. Access to the site is proposed near the Northwest corner at <br />CR 7 and approximately at the center of the propeRy on the South at CR 36. <br />2.0 Trip Generation/Projected Volumes <br />Mining production is projected to reach 335,000 tons per yeaz at maximum capacity. At peak <br />quarterly capacity, the average tons per day is projected to be 1288.46. The following table <br />depicts the annual truck generation anticipated at the site. <br />TABLE 2.1 TRUCK TRAFFIC GENERATION <br />Quarter of the year Dec., Jan., <br />Febr.

Based on an <br />average carrying weight of 23 tons per load, the anticipated truck traffic generation is therefore <br />217 exitting and entering the site day per during this month. The maximum number of trips per <br />day generated by employees will be 40 and the anticipated number of miscellaneous trips <br />generated per day will be 8. The total maximum monthly ADT therefore results in 265 trips. <br />1 <br />
