Haul Road A and Haul Road B. <br /> Regarding the West Fork of Good Spring Creek, the Division approved the use of an access road <br /> (Sturgeon Road, which was a ranch road prior to mining)that is within 100 feet of the creek for a <br /> short distance. However, most of the length of the road is more than 100 feet from the centerline <br /> of the creek (per Map 25B in PAP). Furthermore, the approved probable hydrologic <br /> consequences (PHC) section in the PAP does not indicate that the road will impact water quality <br /> in this creek. <br /> The Collom Haul Road will cross within 100 feet of the Wilson Creek and Jubb Creek shown on <br /> Map 25E of the PAP. Proper Best Management Practices (BMPs) have been employed prior to <br /> any disturbance for the haul road to ensure all surface water runoff is directed through the BMPs <br /> before being released. Much of the Little Collom Gulch will be directly impacted by the Collom <br /> Pit, the temporary spoil pile, and the Section 25 Pond as show on Map 23C of the PAP. The <br /> Section 25 Pond will protect the lower reaches of Little Collom Gulch that will not be disturbed <br /> during mining and reclamation activities within the Collom area. It is not anticipated that any of <br /> the areas that are to be disturbed within the stream buffer zones will have any long term impact <br /> to Wilson Creek, Jubb Creek, or Little Collom Gulch with the proper use of BMPs, sediment <br /> control structures, and clean water diversions. <br /> No other areas within the Collom disturbance footprint will impact any stream buffer zones. <br /> L. Probable Hydrologic Consequences <br /> A discussion of the probable hydrologic consequences of mining and reclamation operations is <br /> contained in Section 2.04.7 of the PAP. The original findings document (1982), an Amended <br /> Findings Document for Permit Renewal No. 1 (1987), and TR-14 (1989) also include discussions <br /> of probable hydrologic consequences. Probable Hydrologic Consequences for the South Taylor <br /> area are included in Section 2.05.6 in Volume 12 and Section 2.05.6 in Volume 15 for the <br /> Collom Area. <br /> Potential Effects on Surface Water Quantity <br /> The Mine will have very limited regional impacts on surface water. This assessment is based on <br /> hydrologic reports from the 1970s and the 1980s, the approved PHC section of the PAP, and past <br /> Division findings. <br /> Monitoring data in Colowyo's Annual Hydrology Reports (AHRs) indicate that there have been <br /> no significant impacts on water quantity of these streams due to mining operations at the Mine. <br /> The data for flow in Taylor Creek below the mine (monitoring point LTC on Map 10 of the PAP) <br /> and data for flow in Good Spring Creek below the mine (monitoring point LGSC on Map 10 of <br /> the PAP) indicate small decreases in flow since 1982; however, these decreases are not <br /> statistically significant(very low R2 values). <br /> Proposed Decision and Findings of Compliance January 5,2023 <br /> Permit Renewal No. 8 Page 139 <br />
