the pond itself is porous. Past experience in the area is that these ponds will not overflow into the Platte <br />River. The Settling Pond will be cleaned out as needed to remove fines and provide good volume for <br />storage. Therefore, a CDPHE discharge permit will not be needed. <br />Section 8.0 Access Road <br />Two existing accesses are present on the site, one, which is a compacted dirt road that meets Highway 9 <br />as shown on Map C -1, which will be the truck route for almost all activity in and out of the site. The <br />access road in the permit area will be compacted dirt or gravel and approximately 30' in width. Water or <br />magnesium chloride will be applied to this road (primarily by the gravel mine personnel) to keep dust <br />down while mine vehicle traffic occurs. The second access is from Platte Drive, to get to the office and <br />the well next to the office. <br />Section 9.0 Acreage Calculations <br />The total permit area is 45.08 acres and the operation will disturb a total of 36.63 acres. <br />The following Table D -1 describes the disturbed acreage types for the life of the operation. <br />Table D -1 <br />Table D -1 <br />Permit Areas <br />Acreage <br />Comments <br />Mine Area 1A <br />12.38 <br />Mine Area 2 <br />3.41 <br />Mine Area 3 <br />3.73 <br />Mine Area 4 <br />12.16 <br />Wash Plant <br />1.10 <br />Roads <br />2.75 <br />Ponds <br />0.30 <br />Other Disturbance <br />0.80 <br />Fringe around excavation area and erosion protection <br />Total Disturbed Area <br />36.63 <br />Undisturbed Area <br />8.45 <br />Total Permit Area <br />1 45.08 <br />Sullivan Aggregate Pit March 2015 D -10 <br />
