• to be impacted in the Colony permit areas. There are many breaks
in the cliffs which the deer utilize to move freely between the
uplands and lowlands. However, local disruption of small-scale
movement patterns is likely in the mine bench (Middle Fork Canyon)
and disposal area (Davis Gulch). Perhaps the greatest effect
related to big game. movement will be increased mortality along
the Parachute Creek corridor during winter. Roadkill rates prob-
ably will be highest early in the project (due to rearrangements
in movement patterns of the local deer population), but should
gradually diminish through the life of the project. Since elk
generally do not frequent the Parachute Creek corridor, it is
not anticipated that there will be any roadkill. Colony may
provide bus service for construction and operational employees
in order to reduce the amount of traffic. It is Colony's belief
that reduction of traffic in this manner will have the greatest
effect in reducing impacts. Colony considered the possibility
of wildlife fencing or underpasses along the access road. Such
a fence would inhibit deer movements. The cost of the fence
• and underpasses cannot be justified when other mitigation methods
are employed.
IMPACTS -- AQUATIC
Possible direct impacts to fishes and other aquatic life include
increased sedimentation and habitat alteration due to diversion,
channelization, road encroachment, dam construction, or other
modifications to the streams. There is also the possibility
of accidental spills of potentially toxic substances.
Construction of mining facilities and access roads may increase
sedimentation of nearby watercourses. Deposition of this sediment
on the stream bottom may cover fish spawning areas and incubating
eggs. Suspended sediments cause increased turbidity, which in
turn inhibits light penetration and thereby reduces primary
