J <br />Section E16.1~2 (a) Continued. <br />(1) The overall grade shall not exceed 1v:lOh (10 percent). <br />(2) The maximum pitch grade shall not exceed 1v:6.6h (16 percent). <br />(3) There shaJ.l be not more than 300 feel of pitch grade exceeding 10 <br />percent within any consecutive 1,000 feet of Clasp I Roads, but ir. no <br />case shall there be any pitch grade over 15 percent. <br />Class I Road profiles are shown on Class I Road Profiles - Haul <br />Roads A, B, C, D, E, E-1 (2~p 37). The grade and pitch require- <br />ments specified above are met for the existing Haul Roads A, B, and <br />C, and the proposed Haul Roads D, E, and E-1. <br />(b) Horizontal alignment. Class I P.oads shall have horizontal align- <br />ment as consistent with the existing topography as possible, and shall <br />provide the alignment requirement to meet the performance standards of <br />30 CFR 816.150-816.156. The alignment shall be determined in accordance <br />with the anticipated volume of traffic and weight and speed of vehicles <br />to be used. Horizontal and vertical alignment shall be coordinated to <br />ensure that one will not adversely affect the other and to ensure that <br />the road will not cause environmental damage. <br />Energy Fuels' coal haulage fleet has been described under Section <br />816.150 (d)(2). Haulage vehicles operate at speeds not exceeding <br />25 mph; however, the horizontal alignment has been determined <br />based on a 40 mph design speed for safety reasons. Horizontal and <br />vertical alignment have been carefully coordinated so that no <br />horizontal curve begins or ends at the cres[ or sag of a vertical <br />curve and in such a manner as to control erosion, simplify drainage <br />design and maximize safety and environmental results. <br />,• <br />816-179 <br />
