Haul Road D will not have sideslope problems, <br />but Haul Road E will have to be stepped for approximately 500 feet <br />due to steep sideslope s. The natural sideslopes are never more <br />_ than 30 percent, and all roadway drainage will be released below <br />the toe of the fill by the use of culverts. <br />(b) No part of any Class I Road shall be located in the channel of an <br />intermittent or perennial stream unless spec ificaliy approved b}• the <br />regulatory authority. <br />As can be seen from Energy Piines No. 1 and 2 Roads (Map 35) and <br />Eckman Park Roads (Map 36), all existing and proposed Class I <br />Roads are located well awav from the channels of intermittent or <br />perennial streams. <br />(c) Stream fords are prohibited unless they are specifically approved <br />by the regulatory authority as temporary routes during periods of construc- <br />tion. The fords shall not adversely affect stream sedimentation or <br />fish, wildlife, and related environmental values.
