RULE 4 PERFORMANCE STANDARDS <br /> <br />Rule 4 Performance Standards 4-19 Revision Date: 8/21/24 <br /> Revision No.: MR-259 <br />Good Springs Creek <br />Streeter Pond was constructed within 100 feet of Good Springs Creek. During construction <br />(sometime during the late 1970’s) and to date this pond has not created any adverse impacts to <br />Good Springs Creek. This structure is not anticipated to have any long-term impacts to Good <br />Springs Creek. <br /> <br />Other structures have been constructed or previously existed within 100 feet of Goodsprings <br />Creek and they include Colowyo’s access road off of Highway 13 where it crossing Goodsprings <br />Creek and Colowyo’s guard shack. Colowyo constructed the access road to the mine and the <br />guard shack at the beginning of the Colowyo Mine. To date the access road and guard shack <br />have not created any adverse impacts to Good Springs Creek, and these long term structures are <br />not anticipated to have any long term impacts to Good Springs Creek. <br /> <br />West Fork of Good Springs Creek <br />The access road to Section 28 Pond off of Highway 13 was not a new disturbance when <br />Colowyo began using it to construct and access the Section 28 Pond. Rather it was premining, <br />pre-existing “ranch” road, that accessed an old ranch home and surrounding valley area. <br />Colowyo made minor upgrades to the road when the Section 28 Pond was constructed. The <br />majority of these upgrades were to allow proper draining through swales across the road. To <br />date the pre-mining ranch road and upgrades have not created any adverse impacts to the West <br />Fork of Good Springs Creek, and it is not anticipated that this road will have any long term <br />impacts either to the West Fork of Good Springs Creek. <br /> <br />Colowyo also has two surface water monitoring and two groundwater monitoring structures <br />(flumes and wells) installed within the stream buffer zone to the West Fork of Goodsprings <br />Creek. This includes LWFGSC, UWFGSC, A-7 and A-8 as presented on Map 10C. All four <br />monitoring structures have not and will not create any adverse impacts to the West Fork of <br />Goodsprings Creek. <br /> <br />Taylor Creek <br />Colowyo constructed Haul Road A and B within the stream buffer zone which crosses Taylor <br />Creek. During construction (late 1970’s to early 1980’s) and to date, the haul roads have not <br />created any adverse impacts to Taylor Creek. These long term structures are also not anticipated <br />to have any long term impacts to Taylor Creek. <br /> <br />In 2018, Haul Road A will be widened to facilitate equipment movement from the existing <br />facilities and South Taylor Pit to the Collom area. Haul Road A will have mechanically <br />stabilized earth (MSE) walls constructed in locations very near to Taylor Creek to limit <br />disturbance and protect Taylor Creek within the stream buffer zone area that already contains the <br />footprint of Haul Road A. Best management practices (BMPs) including silt fence, s-fence, <br />wattles, or other items at the discretion of the field engineer will be installed and maintained <br />during the widening of Haul Road A to protect Taylor Creek. Once Haul Road A outslope is <br />stabilized the BMP’s will be removed. Utilization of BMP’s during construction and until the <br />outslopes of the road are stabilize will minimize any potential impacts to Taylor Creek. It is <br />anticipated that the Haul Road A footprint will not have any short or long-term impacts to Taylor <br />Creek.
