To mitigate for this and provide for the safety of the traveling public, residents, and mine traffic, the route <br />proposed for use by haul trucks needs to be improved to minimum county standards. Per LPLUC 74- <br />91(c), design standards for such projects dictate: <br />1. Roads carrying 80-999 ADT (40 to 499 one-way trips) Local, 10 plus units require a surface width <br />of 24 feet plus 3 -foot shoulders (total 30 feet) and have 60 feet of Right of Way <br />2. Roads with more than 400 ADT (200 one-way trips) need to be paved <br />3. Site distance must be provided and designed at all driveways and intersections as prescribed <br />4. Horizontal alignment must be provided as prescribed <br />With respect to traffic safety, the project would only be compatible upon completion of all required <br />improvements identified in the previously mentioned draft RIA. <br />As previously stated, typically projects complete all public improvements prior to commencing use. <br />Within the draft RIA, a schedule was developed for recommendation which would allow operations to <br />continue as the road improvements were "phased" over time; contemplating reduced truck hauling <br />allowances until the improvements would be completely implemented. Please see Table 7 for the scaled, <br />phased development considerations for recommendation. <br />Background and GCC's Proposal <br />Through approximately 2010, GCC haul trucks traveled to both the north and the south. The north route is <br />the 6.4 mile segment that is the subject of this permit review as GCC has self-selected this route despite the <br />availability of other possible options. There are two routes to the south — one which takes north CR 120 to <br />meet SH 140 near Breen and the other which takes south CR 116 to CR 119 to meet SH 140 near Kline. <br />In 2010, accident reports identify the potential for both ends of CR 120 to become blocked, which <br />produced the local fire district (Fort Lewis Mesa) expressing concern with such potential relative to heavy <br />traffic/loading upon both the north and south routes. This brought the overall increase of truck hauling <br />transport to the County's attention, and led to the County notifying GCC of the need for a land use permit. <br />As part of a land use permit, GCC would need to improve any roads and intersections it used to county <br />standards. When GCC submitted their land use application in 2012, it had identified north CR 120 as its <br />designated route. Table 5 shows the scale of improvements that would be needed with the various <br />transport options. <br />Table S.

Table 6 shows <br />how traffic patterns shifted as GCC increased its production and rerouted its traffic. <br />Project No. 2012-0089 PC <br />4852-5627-2942, v. 3 <br />Page 17 of 32 <br />(DM, VS, DP) <br />
