a continuing or recurring change, the water control plan must be
changed and the required approval obtained from HQUSACE. Pricing
policy for changes in project operations requires that non-Federal
interests be responsible for payments/repayments equalling the
following:
(1)
Any new construction costs and new operations costs (100
percent);
(2) A share of joint-use project operation, maintenance and
replacement cost, based on use-of-facilities storage allocation;
(3)
Benefits foregone;
(4) Compensation to others for losses in their operations (may
be the same as (3) above); and
(5) An amount equal to one-half the savings to the benefited
non-Federal interests (least cost alternative minus the specific costs
of the modification listed in (1) through (4) above).
g. Single Purpose Water Supply. Single-purpose water supply
projects will not be recommended as Federal projects by the Corps. A
proposed project which includes M&I water supply will be defined as a
single-purpose water supply project where less than 20 percent of the
anticipated NED benefits are attributable to flood control,
navigation, environmental restoration, and/or agricultural water
supply. (This definition does not apply to proposed modifications to
existing projects.) An exception is possible if separable,
economically justified storage is required to realize flood control,
navigation, environmental restoration, and/or agricultural water
supply benefits. In this case, at least 10 percent of the total NED
benefits must be attributable to these purposes for the project to be
considered multi-purpose.
h. Withdrawal and Conveyance Systems. Releases through a dam,
into the stream, are frequently used to convey water from an
impoundment to downstream users. It is the user's responsibility to
protect the releases made for it from intervening diversion or
consumption. The feasibility report must present the evaluation of
alternative water supply measures, which must consider the costs of
all facilities needed to withdraw and convey water from the various
sources to user's system, the impact on project justification of both
including or not including these facilities, and the ability and
willingness of potential water users to pay for the delivery system.
Withdrawal and conveyance facilities may be incorporated as components
of Federal projects when they are essential components of plans for
effective development and use of water resources for flood control,
M&I water supply, agricultural water supply (irrigation), navigation,
hydroelectric power production or other purposes in which Federal
interest resides. (This provision does not extend to inclusion of
local water distribution systems.) If, prior to initiation of project
construction, one or more users can be found to enter into an
agreement for repayment of conduit costs, the conduit may be included
as part of the dam structure. These costs will be identified as
