D. Environmental Impacts

This site is located on open grazing land owned by the Town of Minturn. As previously
mentioned, the east side valley slope is a winter elk grazing area. During the construction phase
of this project an access road will need to be constructed and the tank site excavated, these
operations should have no significant lasting impacts on the environment. All peripheral areas
disturbed during the construction of the tank, road and tank pipeline will be restored to original
conditions as part of the project. A summer/autumn period of construction should minimize
any impacts to the winter use of this general area by elk.

E. Land Requirements

The site is located on town owned property and will not require any special land allocations or
easements. The proposed site is not currently within the incorporated boundary of the Town
of Minturn, but will be annexed as part of the project. This annexation will avoid the need to
attain a 1041 permit and approval from Eagle County. The tank site will occupy approximately
1.4 acres.

F. Construction Problems

Although the tank site is located on a moderately sloped area, access to the site will be steep.
A permanent access road will need to be constructed to the tank site, The tank supply line will
also be located on a steep grade, up to 40%, and will need to incorporate mechanical joint pipe
and special anchoring. The supply main will be buried a minimum of seven feet. Some rock
excavation is anticipated during construction, but should not significantly affect constructability
or cost. The alignment of the tank supply line crosses the Southern Pacific Railroad right-of-way
and the Eagle River. A 75 foot to 100 foot boring will be required beneath the railroad tracks.
Preliminary design indicates that the river crossing will most easily be accomplished by attaching
the water main to an existing bridge structure, using a carrier pipe and insulation to protect the
main from freezing, The pipe will attach to the northwest (downstream) side of the concrete
beam which spans the river and will pass through the concrete bridge abubnents

G. Cost Estimate

1, Construction. Construction costs are estimated based upon a 600,000 gallon storage tank.
Since, this site does not require that a more expensive buried concrete tank be constructed, the
estimate is prepared assuming an above ground steel tank is used, The construction cost for the
tank with appurtenances, supply line, and access road are estimated to be:
