• Maximum Operating Speed 40 mph <br />Maximum Sustained Grade 5 percent <br />Maximum Grade at County Road Intersections 4 percent <br />Minimum Radius Horizontal Curve 500 feet <br />Roadway Width 30 feet <br />Stopping Distance (Crest of Vertical Curve) 325 feet <br />Vehicle speed on the haulroad will not exceed 35 mph. However, the <br />horizontal alignment has been determined based on a 40 mph design <br />speed for safety reasons. Horizontal and vertical alignment have been <br />carefully coordinated so that no horizontal curve beg4ns or ends at <br />the crest or sag of a vertical curve and in such a manner as to <br />control erosion, simplify drainage design, maximize safety and <br />environmental protection, and follow the existing natural topography. <br />The grade and pitch requirements specified under Rule 4.03.1(3) have <br />not been exceeded in road design, as shown on Map 14, Haulroad Profile <br />• and Cross-Sections. The schematic diagram also shows that road cuts <br />and embankments will not surpass the standards stipulated in Rule <br />4.03.1(3). <br />Road embankments have not been placed on steep slopes and do not <br />contain large consolidated overburden fragments. The materials used <br />to construct the haulroad are devoid of acid or toxic forming <br />substances. No fill materials were placed on vegetation or topsoil <br />during embankment construction. <br />Cut and fill slopes have been mechanically stabilized by "cat- <br />tracking." All embankment slopes lacking a protective vegetative <br />cover will be broadcast seeded during the first appropriate planting <br />period. <br /> <br />• . ~~ <br />_-- ~ 2.05-9 <br />
