Mr. Gregg Squire -2- January 10, 1985 <br />Drop structures were installed at two locations where the road <br />had been switchbacked and a rip-rapped channel was installed <br />at the base of the cut slope on the switchback. Bear traps were <br />installed as specified in the design as energy dissipators at <br />two locations along the toe of the cut at the switchback. <br />Ditches as specified in the design had been constructed to carry <br />runoff from the road and were relieved as specified in the design. <br />Cut slopes were reduced to a maximum slope of 1v:1.5h and the <br />disturbed area was reclaimed using the seed mixture listed in <br />Table 5-7 of the revised permit application dated December 14, <br />1982. The road was crowned with 3/4" minus aggregate as a top <br />course. <br />Exhibit 1 sheets 1 and 2 show the road as built including the <br />location of all culverts, ditches, and other drainage facilities. <br />Exhibit 2 shows selected cross sections of the road to illustrate <br />road and slope configurations. <br />I certify, based on my field <br />approved design as part of the <br />the Carbon Junction Mine, that <br />constructed as specified in the <br />by the MLRD. <br />Terry D./~~uer v <br />Colorad Registered P.E.
