McCiane Canyon Mine Expansion and Fruita Loadout Facility Biological Assessment
mulched to promote vegetation, which would result in reduced runoff volume and trap sediment;
and 4) a berm would be placed at the toe of the slope and runoff would be treated via the silt
fence. Discharge from silt fences would be routed through flexible pipe and outlet directly into
the vegetation on the banks of Reed Wash in order to minimize bank erosion.
Light Use Roads. Two light use roads would be constructed onsite. Light use road #1 would
be constructed an the outside of the rail loop by adding 10 feet in width to the rail loop roadbed
to provide access to silt fences, ditches, sediment ponds, and the rail loop. Light use road #2 is
approximately 1,500 feet and would provide construction equipment access from 14 Road south
of the mainline tracks to the railroad spur, primarily within the Union Pacific right-of-way (1,000
feet). Light use road .#2. would be constructed with road base gravel. Run-off from the roads
would be directed through silt fences.
Truck Dump. The truck dump is incorporated into Haul Road #2 and consists of a concrete
and steel structure (60x12 -foot). A stacker conveyor would transfer coal from'the truck dump
under the rail tracks to the coal stockpile. The stacker conveyor is approximately 175 feet long
and housed in an $2x8 -foot long diameter corrugated metal pipe.
Coal Stockpile. Clean coal would be moved underground from the truck dump via a. 4 -foot
stacking conveyor and would be stockpiled with a'160 -foot, truss -mounted radial stacker. The
stockpile would be located on a previously disturbed area and would contain up to 40,000 tons
on approximately 2 acres. A concrete reclaim tunnel would be located under the coal stockpile
to collect .and transfer clean coal on rail cars via a 6 -foot wide and 562 -foot long loading
conveyor belt. Fugitive coal dust would be controlled by use of partial enclosures and watering
at all times unless natural moisture is sufficient to control emissions.
Loading System. This system consists of a 20x20-f6ot structural steel building located over
the rail loop. It would stand approximately 120 feet -high. Coal would be transferred from the
coal stockpile via the reclaim tunnel and loading conveyor. The coal would be batch -weighed
and loaded into the rail cars at this location. Propylene glycol would be sprayed on coal and
coal cars as a de-icer to minimize freezing during winter months (see Section 4.3.1.3 for further
discussion).
Sediment Ponds. There would be three (3) sediment ponds (Ponds 1 through 3) constructed
within the Loadout Facility. Ponds 1, 2, and 3 are capable of containing a 25-year.storm event
plus sediment storage. -All ponds would have water pumped into Reed Wash. When dewatering
is required. Sediment would be removed from all ponds when the ponds are 75 percent full of
sediment. Ponds 1, 2, and 3 collect drainage from inside and outside of the rail loop (Pond 1
also collects runoff from the coal stockpile).
Topsoil Stockpile. Topsoil salvaged from construction of the Loadout Facility would be located
within two topsoil stockpiles on a stable surface within the permit area. An effective cover of
non -noxious, quick -growing annual and perennial plants would be seeded or planted during the
first appropriate growing season after removal. A berm' would be constructed around the base
to prevent loss of topsoil from the stockpile.
Other Facilities/Utilities. Other facilities that would be located within the Loadout Facility
include: 1) a maintenance trailer (40x8 -foot) would serve as a shop, office, and covered storage;
2) a 6,000 gallon above ground fuel tank (8x16 -foot); 3)'an approximate 1,000 -foot power line
that would tie into the existing, but extended (by 500400t) GVP line; 4) a transformer (8x12 -foot)
to supply power to conveyor motors, lighting, and other miscellaneous uses; and .5) a motor
control center that would be installed near the reclaim tunnel (8x20 -foot).
Restoration. After the life of the Project, all railroad and facilities would be removed and areas
disturbed by the Loadout Facility would be returned to an industrial and wildlife habitat land use,
