Revised 7/18/83 <br />2.05,3 Operation Plan - Permit Area - Continued: <br />• (3) Mine facilities: <br />There will be no facilities constructed at the loadout <br />site. <br />(4) Ponds. impoundments and diversions: <br />There will be no ponds or impoundments on the Northgate <br />site. Once the topsoil has been removed, water will <br />naturally pond on the property. A 10 year 24 hour storm <br />event would result in the ponding of a maximum of 1 inch ;. <br />of water over the entire property. A pond will not be <br />constructed to control the runoff from the site for the <br />reasons described in section 2.04.7 of this revision. <br />All precipitation which falls on lands adjacent to the <br />loadout will flow away from the property as a result of <br />the natural contours (Figure 1). It has been determined <br />. that neither an interceptor ditch nor berm will be <br />required to divert runoff away from the Northgate <br />property. <br />(5) Topsoil (removal and storage): <br />Scrapers will be used to remove topsoil to a depth of 1Z <br />to 18 inches from the entire permit area. All topsoil. <br />approximately 6500 c.y., will be placed in one stockpile <br />at the western edge of the permit area (Figure 1). The <br />stockpile will be seeded with the seed mix described on <br />page D-2(a) of the permit. <br />(6) Overburden: <br />No overburden will be removed at the loadout site. <br /> <br />• 14 <br />
