6. At the time of
implementation of the
decision by Reclamation
in the Glen Canyon Dam
E'S~ a certain amount of
hydroelectric power will
no longer be available.
Won't the SLCA need to
have replacement power
at that time?

7. Will existing customers
be required to accept the
SLCA's replacement
resources?

8. Will the SiCA consider,
environmental
consequences in
determination of
"economical and
technically feasible"
replacement options?

The SLCA's Replacem~nt Resources Process will help identify what
resources could be us~d by the SLCA to make up this deficit.

Western's EPAMP is a different kind of action than the others described.
In this process, Weste~n proposes that all firm power customers be
required to prepare Integrated Resource Plans for the acquisition of new
resources. Also, the p'roposed program would extend the customers'
Federal resources. !

Yes. The SLCA expects that some amount of replacementresource will be
needed coincidently with changes in the long-term operating criteria and
reductions in the availability of hydroelectric power from GCD following
completion of the GGD-EIS. The amount of short-term replacement
resource needed may be based upon replacement requests by existing
firm power customerf'

Currently, the SLCA Jnticipates a gap between the time when changes in
the Glen Canyon operations are implemented and the date replacement
resource contracts a(e completed. Accordingly, the SLCA expects that
certain short-term supplemental power purchases may be necessary to
satisfy contractual o,?ligations until completion of long-term replacement
resource contracts and firm replacement power deliveries are established.

We do not expect S6. Initially, the SlCA's customers may be offered the
opportunity to purc~ase resources acquired by the SlCA if they so desire,
but will be under nil obligation. The customers presently have the ability
to decide whether ~b purchase the replacement resource on their own,
have the SlCA replfce it, or use their existing resources to make up any
power lost because, of constrained Glen Canyon Dam operations.

Further, the SLCA'sianticipates its customers will have the opportunity to
commit to future r~sol!rce replacements as their resources/purchases
become insufficient to meet their needs. These opportunities may be
provided on a predetermined schedule to help efficient resource plan-
ning.

i
The SLCA will co?sider the environmental consequences of the replace-
ment resources e~amined and will identify potential environmental
impacts such as airpollution in the Replacement Resources Process.

,
The SlCA will prepare environmental documents as required under the
National Environ\T1ental Policy Act. These documents will give the SLCA a
full indication of the environmental consequences of proposed actions.
