2-33 <br />violation of applicable water quality standards. The light use road is not located in any <br />intermittent or perennial streams or wet areas. <br />Light use roads will be located to minimize downstream flooding. Run-off from <br />portions of the light use roads must flow through vegetation before its reaches the <br />nearby ephemeral channel or leaves the permit area so there is some filtering of run- <br />off. <br />The light use road is approximately 8,300 feet long, 8 to 12 feet wide, with an <br />average grade of 3%. Pitch grades are not steeper than 20% for any consecutive <br />1,000 feet. There are no grades that exceed 20%. Side cast construction will be used. <br />Compaction on embankments will be provided by the construction equipment and <br />performed only to the extent necessary to control erosion and maintain the road. <br />Topsoil will be removed and set aside for final reclamation use in any locations where <br />excavation would require replacement of material and redistribution of topsoil for <br />proper revegetation. Vegetation will not be cleared for more than the width necessary. <br />Approximately 4,600 feet of the light use road will be constructed in the bottom of <br />the ephemeral channel. There is no other location feasible to construct the road. The <br />ephemeral channel is the most stable location to minimize erosion. Any attempt to <br />construct the road above the ephemeral channel would cause side cast material to flow <br />into the channel. By shaping the bottom of the ephemeral channel, moving boulders, <br />etc., erosion may be reduced during high flow events since the flow along the channel <br />will not be as turbulent. <br />No surfacing will be utilized for the light use roads. The light use road will be <br />maintained adequate for its intended use and watered as necessary to control dust. A <br />light use road damaged by a catastrophic event will be repaired as soon as is <br />practicable after the damage has occurred. <br />The light use road will be completely removed and the land affected will be <br />regraded to approximate original contour, revegetated and mulched. <br />i• <br />M`Clane Volume 1 11/05 <br />
