Background

Section 2

Like Flaming Gorge, the Aspinall Unit has been undergoing research and recovery test
releases as part of Section 7 consultation under the Endangered Species Act. This five-
year program ofresearch flows and test releases will be in place until 1997. Following
completion of this research, the USFWS is expected to issue a biological opinion on
operations of the Aspinall Unit.

2.2.3.3 OTHER FACILITIES

Although the other SLCA/IP facilities at Fontenelle, Collbran and Rio Grande are not
affected by hourly power scheduling decisions made by Western, operations at these
facilities are also likely to be affected by environmental concerns in the future. While
operational changes at these other facilities would not affect Western's power scheduling
flexibility, the total capacity available to SLCA/IP customers could be reduced.

2.2.4 SLCA INTEGRATED PROJECTS FIRM LOAD

In addition to serving Reclamation project use loads, Western markets SLCA/IP firm
power at "Post-1989" levels. This marketing level was put into effect in October 1996
upon the signing of the Record of Decision (ROD) on Western's Electric Power Marketing
EIS.' For the purposes of this report, the interim allocation contract rate of delivery
(CROD) in effect up until October 1996 has been asswned for the SLCA/IP, as shown in
Table 2,1.
