ACTIVI'l'"'Y TWO - Selecting State/regional Objectives and Desires,
Screening Problems, and Documenting Assumptions
(July 1975 - December 1')75)

The object:ive of this Activity is two-fold. First the final results of the
Nationwide' Analysis will be reviewed and evaluated by the Regional Sp0ns0rs
for the pur.pose of striving to:(l) develop a State/regional set of projections
for eachA'6gregated Subarea and also;(2) establish objectives, desires, ar-d
detailed as sumptions upon which the remaining portions of this Activity and
subsequent Specific Problenl Analysis activities will be based.

These Stat<~/regional projections are referred to in the Plan of Study as the
Regional P.reference Future and are comprised of the same items of information
contained in the Modified Central Case resulting from the Natim wide Analysis
and to be s;upplied to the Regional Sponsor in July 1975.

The items of information in the Modified Central Case to be provided to the
Regional S;::lOnsors in July of 1975 for each of the Aggregated Subareas are
listed in detail in Appendix C; however, they are of the following types:

I. .Estimates of current water use (1975) and projections of water
requirements for 1985 and 2000 based upon variations from
Central Case assumptions.

2. Results of the Volumetric Adequacy Analysis for va.riations from
, .
the 'Central Case which compares requirements against supplies

to determine relative magnitudes of deficiencies.

3. A description of the effects of ,-ariations from the Central Case
on selected measures of national economic development, regional
development, environmental quality, and social well-being.

4. Clearly stated assumptions supporting the Central Case variation
projections, adequacy analysis, and effects.

5. Results of Federal agency identification of within ASA problems.

6. The Modified Central Case as determined by" the ;\;PA Committee
after an analysis of the results of the Central eetSe and variations
therefrom.
