The; spe;cial inle;rim crile;ria will nol1.ake; dfe;cl unlil firm commilme;nls are; in place;
in Calitomia to implement Pha'!e I ofthe 4.4 Plan, including the execution of
binding oontracts, agreed-on arrangements for transportation, and resolution of the
quantifioation and beneficial use issues.

Any interim criteria will be effective only for a specified period of years coincident
with Phase I of the 4.4 Plan, after which the interim criteria will expir:-e on its own
le;rms. The; slale;s ami Inle;rior will ne;e;d lo discuss lhe; lime;-frame; for the; inwrim
criteria suggested in the MWD/SDCW A agreement. After expiration ofthe
interim criteria, the existing Operating Criteria oontinue to oontrol operations,
unless the Secretary modifies the Operating Criteria pursuant to his authority.

Any interim oriteria should include triggers which will imp~ent different surplus
or shortage deliveries at specified target elevations of stora~Such triggers may
need to include an assessment of the water available to MWD fi'om all sources of
supply. Thc oritcria should also include benclunarks, reporting mechanisms, and
reviews, by which California will demonstrate measurable and defined progress in
me;e;ling lhe; goals oflhe; 4.4 Plan. If sufficie;nl progre;ss is nol be;ing made;, lhe;
interim criteria should automatically and hy it'! own terms terminate or suspend,
and operations will revert back to the existing criteria as currently applied, i.e.~
A 19 Btratt:gy .vith DO leek Mead. (:!J

c.

Any interim criteria will not be renewed, except upon review. Phase I of the Plan
does not achieve reduction in use in California to 4.4 maf. Before Phase I is over
and lhe; inle;rim crilt:ria e;xpire;, California should propose; how the; ne;xl phase; will
he developed and implemented. Pha'le II should hegin implementation hefore or
immediately upon the completion of Phase I. New interim. criteria, or a renewal of
the existing interim criteria, may be adopted by the Secretary to allow for
implementation of Phase II ofthe 4.4 Plan, only it'Phase II is ready tor
implementation, and the Secretary has consulted with the states on new or renewed
interim criteria.

f

'Il,e interim criteria should address use of water during shortage and surplus
conditions by the states of Arizona and Nevada.

g.

The interim criteria may need to address the issue of oH:stream storage, whether
during surplus or flood control release conditions, and how such storage should be
accounted under the equalization and 602(a) storage requirements of the Operating
Criteria.
