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 of <br /> the creek (per Map 25B in PAP). Furthermore, the approved probable hydrologic consequences <br /> (PHC) section in the PAP does not indicate that the road will impact water quality in this creek. <br /> The Collom Haul Road will cross within 100 feet of the Wilson Creek and Jubb Creek shown on Map <br /> 25E of the PAP. Proper Best Management Practices (BMPs) have been employed prior to any <br /> disturbance for the haul road to ensure all surface water runoff is directed through the BMPs before <br /> being released. Much of the Little Collom Gulch will be directly impacted by the Collom Pit, the <br /> temporary spoil pile, and the Section 25 Pond as show on Map 23C of the PAP. The Section 25 Pond <br /> will protect the lower reaches of Little Collom Gulch that will not be disturbed during mining and <br /> reclamation activities within the Collom area. It is not anticipated that any of the areas that are to be <br /> disturbed within the stream buffer zones will have any long term impact to Wilson Creek, Jubb <br /> Creek, or Little Collom Gulch with the proper use of BMPs, sediment control structures, and clean <br /> 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 of <br /> probable hydrologic consequences. Probable Hydrologic Consequences for the South Taylor area are <br /> included in Section 2.05.6 in Volume 12 and Section 2.05.6 in Volume 15 for the 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 no <br /> significant impacts on water quantity of these streams due to mining operations at the Mine. The data <br /> for flow in Taylor Creek below the mine (monitoring point LTC on Map 10 of the PAP) and data for <br /> flow in Good Spring Creek below the mine (monitoring point LGSC on Map 10 of the PAP) indicate <br /> small decreases in flow since 1982; however, these decreases are not statistically significant (very <br /> low W values). <br /> 35 <br /> Permit Revision No.5(PR-05),C-1981-019 <br />
