RULE 4 PERFORMANCE STANDARDS <br />were installed and removed are owned and operated by WREA. The final locations that will be <br />serviced and potentially create ground disturbance will be determined by WREA. These ground <br />disturbing activities are not associated with the Colowyo's mining activities, and will not be <br />required to be permitted nor bonded for in accordance with Rule 3.02.1(2). <br />In 2017, Chevron dug up and capped an existing unused oil line in several locations just south of <br />the Gossard Loadout facitlies within the Colowyo permit boundary. These ground disturbing <br />activities are not associated with the Colowyo's mining activities, and will not be required to be <br />permitted nor bonded for in accordance with Rule 3.02.1(2). <br />At various times during the mine life of the Colowyo operation, Colowyo as a private landowner, <br />will construct new ranch roads and/or repair or upgrade existing ranch roads within the permit <br />boundary. These activities are not associated with the mining operation and will only occur outside <br />of the permitted disturbance boundary. Please see Maps 19, 19B, and 19C for the permitted <br />disturbance areas. The construction and/or repairs to these ranch roads will factilitate ongoing <br />private landowner activities including ranching, grazing, hunting, and access for other entities <br />which hold right of ways within the permit boundary. These ranch roads activities are not <br />associated with Colowyo's mining activities, and will not be required to be permitted nor bonded <br />for in accordance with Rule 3.02.1(2). <br />White River Electric Assoication (WREA) will construct, operate, and maintain a 69 kV power <br />line from the Axial Basin substation adjacent to State Highway 13 to the Collom facitlies area. <br />This power line will be wholly owned by WREA. The ground disturbing activities associated with <br />construction of the power line, including pole locations and roads to pole locations, are not <br />associated with Colwoyo's mining activities, and will not be required to be bonded in accordance <br />with Rule 3.02.1(2). The power line will service the area post -mining in Collom. <br />Tri-State Generation and Transmission Assoication, Inc. (Tri-State) owns and operates the Axial <br />Basin Substation, which provides electrical services locally in the the Axial Basin area including <br />to Colowyo. Tri-State will be expanding the footprint of the substation within the permit boundary <br />on the east and west side of the current substation location. The ground disturbing activities from <br />the expansion of the Axial Basin Substation are not associated with Colowyo's mining activities, <br />and will not be required to be permitted nor bonded for in accordance with Rule 3.02.1(2). <br />In 2018, approximately 22 acres within Colowyo's permit boundary (outside of the disturbance <br />boundary) was affected by the wild land fire caused by a lighting strike. The location of the fire is <br />shown on Figure 4.12-6. The area that was burned is mostly comprised of pinyon juniper and low- <br />density sagebrush. Because the fire was not related to Colowyo's mining activities, Colowyo, as <br />the surface landowner will reseed or managed the post -fire area, as it deems appropriate. <br />4.13 Contemporaneous Reclamation <br />All reclamation actives, including but not limited to backfilling, grading, topsoil, replacement and <br />revegetation, will be carried out as contemporaneously as practicable with mining operations. <br />Implementation of the reclamation plan, as described in Section 2.05.4, will assure that each step <br />in the reclamation process is completed in a timely manner. <br />Rule 4 Performance Standards 4-40 Revision Date: 11/27/18 <br />Revision No.: TR -129 <br />
