The Colorado Squawfish, which is currently listed as an endangered species, is not present in this
section of the Colorado River due to a downstream dam near Cameo. The Squawfish is generally
present 2 to 3 miles downstream from the subject site. The aquatic life which is present in this
section, and is proposed to be added to the endangered species list, is the Razorback sucker fish.
CDFW has placed a physical activity limitation on this section of the Colorado River during
Razorback sucker fish spawning season. The spawning season for Razorback sucker fish is during
the months of May and June.

The other endangered species present in the subject area is the Bald Eagle. The Bald Eagle is
found to generally nest in mature Cottonwood trees, and therefore, removal of such trees during
construction is not permitted.

The pipeline crossings of the Colorado River are proposed to be conducted during September,
October, and November, a time which generally presents low flow in both the Colorado River and
Plateau Creek. This schedule mitigates impact to the spawning of the Razorback sucker fish. The
proposed pipeline alignment has also been modified to avoid eradication of any mature Cottonwood
trees.

6.3.7 Denver Rio Grand Railroad

A section of the proposed pipeline along the west bank of the Colorado River will be located on
the Denver and Rio Grand Railroad (D&RGR) land. The D&RGR was contacted as part of
permitting process to determine their requirements for acquisition of Construction Right-of-Way.
The construction on D&RGR land will require a construction permit. As part of this permit,
drawings presenting the detail location and cross sections should be submitted to D&RGR Engineer
section for evaluation and approval.

The cost for obtaining construction Right-of-Way from D&RGR is estimated to be about $3000.00
per acre per year. This will include a permanent maintenance easement.

6.4 Design Considerations

The alignment proposed by WEI was selected for design consideration evaluation. This alignment
appears to be appropriate except in the following areas:

I) In the vicinity of the Plateau Creek Information Area, WEI aligns the pipe to jog
around the center and continue to the north adjacent to Highway 65. The presence
of a grove of cottonwood trees on the alignment which cannot be removed during
