b. Paradox Valley-Construction of
evaporation ponds are included in
the total"costs of the project.
Additional construction costs are
approximately $26.9 million.

c. The addition of Reclamation's Lower
Gunnison-Laterals Project to the
program. This increases program
costs approximately $47 million
($45.0 million for construction costs
and $1.8 million for O&M costs).

d. Price-San Rafael (USDA) unit
construction has been rescheduled
to begin in the year 2009. The total
costs covered during the 2009 to
2015 period is approximately
$15.3 million. This is approxi-
mately a $7.0-million-dollar
reduction in program costs for this
time period. Price-San Rafael
(USBR) construction is also
rescheduled for the same period
(2009 to 2015). This change results
in a reduction in total costs of
$17.5 million.

e. San Juan (USDA) project is
eliminated from the project. This
reduces program costs by
approximately $2.2 million.

f. Construction costs for Grand Valley
Stage II is reduced by approxi-
mately $5.5 million.

g. Uinta Basin (USDA) project costs
increased by approximately
$4.9 million.

Various projects also have some smaller
construction cost increases. There are
additional costs due to indexing project costs
from October 1990 dollars to October 1992
dollars. The net impact on project construction
costs is an increase of approximately
$59.9 million. The net impact on changes to
O&M costs is a decrease of approximately
$99 million.

4. There is also a significant increase in
the dollars spent on salinity control
projects from 1990 to 1992. Dollars
spent to date are deducted from the
total costs ofthe Salinity Program to
derive the estimated cost of the current
Salinity Program. The increase in
dollars spent between 1990 and 1992 is
approximately $84.2 million.

The effect of all these changes (expressed in
millions of dollars) to the 1991 JER repayment
spreadsheet is summarized below:

Estimated remaining costs in 1991 JER
< repayment spreadsheet: $603.86.

1. Net change in current project
construction costs: +$59.94.

2. Net change in O&M costs: -$99.163.

3. Net change in dollars spent from 1990
to 1992: -$84.19.

Estimated remaining costs in 1993 JER
repayment spreadsheet: $480.45.

Repayment spreadsheet No. 1 contains the
Lower Colorado River Basin Development
(LCRBD) Fund balance of$18,795,000 as of
1992. From 1993 to 1997, projected revenues
have been revised downward from the 1991 JER
annual revenue projection of$9.1 million to
approximately $8.3 million. From 1998 to 2010,
projected annual revenues have been revised
upward from $9.1 million to $9.2 million, and
this estimate is projected to 2015. Estimated
annual repayment costs for the Lower Colorado
River Basin States are deducted from the
LCRBD Fund from 1993 to 2015. For those
years in which the repayment costs are greater
than the balance in the LCRBD Fund, there is a
deficit in the Fund, and interest on that deficit is
calculated and added to the deficit amount. The
deficit balance is then added to the next year's
repayment costs. The 7.375-percent interest
rate used to calculate any interest charges is the
rate applicable for fiscal year 1993 and is to be
applied on repayment of projects under the
Colorado River Basin Salinity Control Act. The
projected balance in the LCRBD Fund for the
year 2015 is $116.1 million.
