Plans have been assigned to one of five categories. Assignment
to categories is based on cost, TVS, and anticipated severity of
institutional problems. The categories are as f0Ilow~:

Cateaorv II - Plans that are highly cost effective and appear to
have no unresolvable political or institutional problems. These
plans warrant further con~ideration.

Cateaorv III - Plans that are marginally cost effective and
appear to have no unresolvable political or institutional
problems. These plan~ would only be considered further if all
Category I and II plans were found to be unworkable.

Cateaorv IV - Plans that are cost effective but appear to have
unresolvable political or institutional problems. These plans
would be not considered in the future unless the political or
institutional climate changes. Plans dropped from consideration
early in the study are also included in this category.

Cateaorv V - Plans that are not cost effective and do not warrant
further consideration.

Plans considered infeasible are those with annual operating costs
greater than the currently projected annual costs of operating
the YDP. Because the cost estimates are not precise, the cutoff
for cost was assumed to be the annual operating cost of the YDP
plus 10 percent.

RESULTS

The analysis shows that a number of proposed plans exhibit
potential for cost savings ranging from a few percent to more
than 50 percent. Some plans appear implementable while others
appear to face insurmountable problems. Table 2 shows the
proposed plans listed by category.

RECOMMENDATIONS

Forty eight proposed plans have been evaluated. Twleve plans
have cost saving potential and appear implementable. Since the
evaluations have been completed using a limited amount of
preliminary data, more detailed analysis is required before a
final plan is selected for implementation.

The following work items are recommended to be included in the
next level of evaluation of proposed plans having significant.
