collection berms will be established downslope of the area to direct the estimated 0.12 of of runoff (from the 10- <br />year, 24-hour event) to either the containment azea to the west, or to the two rock filters on the north side. <br />• In order to provide access to the dewatering boreholes, the two light-use roads will be connected to form a pad <br />between the wells. The available topsoil will be windrowed to the sides of the pad and will be stabilized with the <br />approved seed mixture. The graveled pad and roads are within the confines of the 2.0 acre SAE area as shown on <br />Map 26, Fish Creek Borehole and Facilities and Access Road. <br />In reference to the boreholes and control building area, collection berms will be established downslope of the area <br />to direct an estimated 0.12 acre-feet of runoff from the 10-year, 24-hour event to either the adequately-sized natural <br />depression west of the area, or to a pair of rock filters on the north side. <br />Fish Creek Ventilation Borehole -Another SAE exists at the Fish Creek Ventilation Borehole. A vegetative <br />filter will provide sediment control for the 0.6 acre area of disturbance. Until the vegetation becomes reestablished, <br />however, the 0.06 acre-feet of runoff from the 10-year, 24-hour event will flow to the collection area azound the <br /> <br />L_:J <br />TR07-59 2.05-79.2 03/26/07 <br />
