Revised Supplemental Draft Environmental Assessment-Chapter I-Introduction

site (known as the Jacobson Hydro No.1 Project). The project was put on hold in 1994,
and has not been constructed. FERC amended the Jacobson Hydro No.1 license in
September 2001 (FERC,2001). The amendment included the means to reimburse the
licensee for the cost of the fish passage. The maximum amount of the reimbursement
was the anticipated cost of the least cost passage alternative. The license was terminated
by FERC on July 15,2002 (FERC 2002C). Reclamation's implementation offish
passage at the Price-Stubb Dam was dependant on FERC's decision on the amendment
and/or the licensee's decision to proceed with hydropower development. The licensee
has not abandoned plans for hydropower development at the site.

,Scope

Reclamation developed fish passage alternatives and identified issues or concerns with
participation from many individuals, agencies, and organizations that may be affected by
the project. Alternatives discussed in Chapter 2 are: No Action, Conventional Fish
Ladder, Downstream Rock Fish Passage, Downstream Rock Fish Passage with
Whitewater Recreation Features, and Dam Removal. This Revised Supplemental
Draft EA refines the Downstream Rock Fish Passage Alternatives that were evaluated in
the Supplemental Draft EA (Reclamation, 2002a).

Water Resources

Ute Water Conservation District (Ute Water) Pump Plant Intake-Ute Water
provides domestic water to over 60,000 Grand Valley residents via a pipeline from
storage reservoirs. Their emergency backup water supply is pumped from the Colorado
River out ofthe pool formed by the Price-Stubb Diversion Dam. Dewatering upstream of
the dam or dam removal could adversely affect Ute Water's ability to pump water from
the river during low river flows.

Water Rights-Owners of existing water rights with points of diversion at the Price-
Stubb Diversion Dam have raised issues regarding potential impacts and the future
utilization oftheir water rights under the Dam Removal Alternative.

Clifton Water District-Downstream Water Quality-Changes in water quality
downstream from the dam may affect the ability of Clifton Water to meet drinking water
standards and provide domestic water to approximately 30,000 people.

Ute Water Pump Plant-Spring Flooding-the fish passage alternatives may affect
spring flooding of the Ute Water pump plant.
