RULE 4 PERFORMANCE STANDARDS
final locations to be disturbed will be determined by IMR. These ground disturbing activities are
not associated with the Colowyo's mining activities, and will not be required to be permitted nor
bonded for in accordance with Rule 3.02.1(2).
In 2016, approximately 4 acres within Colowyo's permit boundary was affected by the moderate
intensity wild land fire. The location of the fire is shown on Figure 4.12-5. The area that was
burned is mostly comprised of Gambel's Oakbrush and low density sagebrush. Additional surface
disturbance within the permit boundary of approximately 1.4 acres was created to cut in a fire line
to control and fight the fire. The relatively low intensity nature of the fire does not appear to
warrant or require supplemental seeding; however, the area impacted by the fire line will be
smoothed over and seeded with the approved reclamation seed mix.
In the fall of 2016 and spring of 2017 White River Electric Assoication (WREA) installed and
removed powerlines located within the Colowyo permit boundary. The powerlines that were
serviced are located adjacent the Gossard Loadout facility (an overhead line will be buried) and
Jubb Creek (new overhead line) north towards Moffat County Road 32. These powerlines that
were installed and removed are owned and operated by WREA. The final locations that will be
serviced and potentially create ground disturbance will be determined by WREA. These ground
disturbing activities are not associated with the Colowyo's mining activities, and will not be
required to be permitted nor bonded for in accordance with Rule 3.02.1(2).
In 2017, Chevron dug up and capped an existing unused oil line in several locations just south of
the Gossard Loadout facitlies within the Colowyo permit boundary. These ground disturbing
activities are not associated with the Colowyo's mining activities, and will not be required to be
permitted nor bonded for in accordance with Rule 3.02.1(2).
At various times during the mine life of the Colowyo operation, Colowyo as a private landowner,
will construct new ranch roads and/or repair or upgrade existing ranch roads within the permit
boundary. These activities are not associated with the mining operation and will only occur outside
of the permitted disturbance boundary. Please see Maps 19, 19B, and 19C for the permitted
disturbance areas. The construction and/or repairs to these ranch roads will factilitate ongoing
private landowner activities including ranching, grazing, hunting, and access for other entities
which hold right of ways within the permit boundary. These ranch roads activities are not
associated with Colowyo's mining activities, and will not be required to be permitted nor bonded
for in accordance with Rule 3.02.1(2).
White River Electric Assoication (WREA) will construct, operate, and maintain a 69 kV power
line from the Axial Basin substation adjacent to State Highway 13 to the Collom facitlies area.
This power line will be wholly owned by WREA. The ground disturbing activities associated with
construction of the power line, including pole locations and roads to pole locations, are not
associated with Colwoyo's mining activities, and will not be required to be bonded in accordance
with Rule 3.02.1(2). The power line will service the area post-mining in Collom.
Tri-State Generation and Transmission Assoication, Inc. (Tri-State) owns and operates the Axial
Basin Substation, which provides electrical services locally in the the Axial Basin area including
tu Colowyo. Tti-Stag, will be-expanding the footprint of thc substation within the p..r nit boundary
on the east and west side of the current substation location. The ground disturbing activities from
