• The haulroad will be crowned to prevent ponding and to conduct <br />water into side ditches. Surface runoff from the road will be <br />intercepted by diversion ditches and conveyed into the detention basin <br />prior to being released into the natural drainageway. Thereby, <br />drainage from the haulroad will meet the requirements of Eule 4.05. <br />The sediment control system for Nine No. 3 vas designed to safely peas <br />the peak runoff from a 10-year, 24-hour precipitation event. <br />Calculations are included in Sahibit 3, Sediment Control plan. <br />Sediment control structures aze discussed in detail under Bule 2.05.6 <br />(3). <br />Neasurea to control erosion within the disturbed area may include <br />• stabilizing eapoaed surfaces with straw dikes, rip-rap, check dame, <br /> mulches, vegetation sediment filters or other devices that reduce <br /> overland flow velocity, decrease runoff volume, or trap sediment. One <br />or more of these erosion control measures will be implemented as <br />needed. <br />Surfacing <br />The Colorado Yampa Coal Company proposes to surface the haulroad <br />with the granular spoils eziating at the mine site. These materials <br />have historically proven to be sufficiently durable with proper <br />maintenance. No acid- or toxic-forming substances are present in the <br />proposed surfacing materials. <br />• <br />2.05 - 16 <br />
