During the primary hauling season of approximately 30 weeks (180 days, M-Sa), this is reduced to o Total 44 ADT with 50% entering and 50% exiting. 0 16 are estimated to be combination or single trucks, and 0 10 are estimated to be small/personal vehicles. • During the slow hauling season of approximately 18 weeks (90 days, M-F): o Total 33 ADT with 50% entering and 50% exiting. 0 9 are estimated to be combination or single trucks, and 0 8 are estimated to be personal vehicles. Since both generators are regulated by permits or physical conditions, traffic for life of the operation is assumed to remain constant (on an annual basis)with no increase in traffic generated. When averaged over 365 days per year, AADT is 64 PVE. See Appendices A and B for calculations (omitted). See Table 6-1 for summary. Information on internal and/or pass-by trip reductions, if any: NONE During the life of the operation, a certain amount of material produced in this operation will be used internally by the Dutton Ranch and will NOT use the access road or be transported by county or state highway. This material is not included in permit limits and not included in this study, as the materials will not be removed from the site via state or county roads. Figure M4A-3. Peak Movements Table 6-11.

Commuters(miners)will generally arrive/leave before and after peak hour. 7. Trip Distribution Based on anticipated markets during the life of the pit, traffic on public highways is assumed to be 90 percent southbound and 10 percent northbound, all on CR-600 (Piedra Road). CR-600 connects to various county roads and city/subdivision/metropolitan district streets before connecting to SH-160 west of Pagosa Springs in the Pagosa Lakes area (SOUTH) or crossing into Hinsdale County (as FSR-630) (NORTH). It is further assumed, for lack of detailed market information, that traffic EAST and WEST on SH-160 will each be 45% of total traffic generated by the operation. Therefore, this study assumes that average peak-season truck traffic for purposes of analysis will be 44 round trips per day, 40 South and 4 North, with peak traffic counts of 18 per hour (generally 0700-0800 and 1700-1800 depending on time of year). Those Southbound are estimated to include 1 or fewer going to roads/streets off CR-600, 9-10 going East on SH-160, and 9-10 going West on SH-160.
