This document provides a brief description of the Central Valley Project (Project) and the details of the proposed new municipal and industrial (M&I) ratesetting policy (hereafter referred to as the Proposed Policy) for the Project.

Throughout this document, a number of key terms are used which have specific meanings in reference to the Proposed Policy.  Definitions of these key terms are provided in the GLOSSARY section of this document.

Accompanying this Public Review Document is a booklet entitled "1993 M&I Rates for the Central Valley Project."  This booklet (hereafter referred to as the 1993 M&I Rate Book) includes the following two sections:

Public meetings will be conducted in appropriate locations in the Project service area and oral and written comments on the Proposed Policy will be obtained. The Proposed Policy will be revised as appropriate, in response to the comments received.  The Proposed Policy will then be submitted to the Department of the Interior (Department) for final approval along with a summary of the comments received, the Bureau of Reclamation's (Reclamation) responses and/or descriptions of the changes made to the Proposed Policy, and appropriate environmental documentation required by the National Environmental Policy Act (NEPA ). The approved policy will be implemented as the new Project M&I Ratesetting Policy.

An M&I water ratesetting policy is needed for the Project in order to assure that costs allocated to the M&I water function are repaid by the end of the Project repayment period.   The Proposed Policy will meet this repayment requirement.  With minor variations, the Proposed Policy has been used on an interim basis in setting the Project's M&I water rates for the past several years.


The Project was authorized by the Act of August 26, 1937, and has since been reauthorized several times to include new features and operating measures. The Project was designed for coordinated operation of its surface reservoirs and canals with existing rivers, streams and ground water supplies. Project operations are coordinated to maximize water yield and delivery and efficiency of operations. The Project catches and stores the mountain runoff and, through a complex web of storage and diversion dams, pumping plants, canals and distribution facilities, delivers water throughout its authorized service area.

The Project provides multiple benefits associated with water resources management activities. Although initially developed for irrigation and flood control, the Project now supplies M&I water throughout the Basin, generates hydroelectric power, provides water for fish and wildlife and water quality enhancement, offers recreational opportunities, and provides other benefits and services as well. The Western Area Power Administration of the Department of Energy operates the power transmission features, while the power generation features and all other Project functions are the responsibility of Reclamation.

Passage of the Central Valley Project Improvement Act (CVPIA) in October 1992 increased the emphasis on operating the Project in a more environmentally sensitive manner requiring improved water conservation and expanded use of voluntary water transfers, and use of a balanced approach to meeting the competing demands for Project water by fish and wildlife, agricultural, M&I, and power components of the Project.

The Project's plant in service costs were $3.01 billion as of September 30, 1991, $2.91 billion applicable to Reclamation's facilities and $100 million applicable to Western Area Power Administration power facilities. Reclamation's plant in service costs include $485 million for facilities constructed by the Corps of Engineers which have been integrated into the Project for operational and repayment purposes. The Project's September 30, 1991, plant in service costs by type of facility are summarized in Table 1 below.

Costs allocated to the M&I function are to be fully repaid by the end of the authorized repayment period. The capital costs of the existing in-basin and out-of-basin facilities are to be repaid by the end of their repayment periods of 2030 and 2036, respectively, as explained on page 6. Capital investment costs are repaid with interest. Annual O&M costs, including interest on unpaid capital and deficits, which are not repaid within the year incurred, become deficits and must also be repaid with interest.

The Proposed Policy will repay the unpaid balance amounts shown in Table 3 within the authorized repayment periods. Upon approval, the Proposed Policy will be used to determine the individual contractor's M&I water rates required to repay these unpaid balances. While existing contract provisions will continue to be honored during each contract's term, the M&I water rates will be implemented as soon as possible throughout the Project.


Both the irrigation and M&I functions of the Project are integral water delivery operations governed by common requirements, criteria, and principles. The integrated operations and common characteristics dictate consistency and uniformity in the ratesetting policies for these two functions wherever possible. Accordingly, the basic principles, criteria, and methodologies established by the irrigation ratesetting policy provided the broad framework upon which the Proposed Policy was based.

Two fundamental concepts underlie the Proposed Policy:  Individual Contractor Accounting, and Cost of Service water rates.

-- Individual Contractor Accounting refers to (1) determination of annual water rates, (2) the annual accounting for O&M, and (3) interest expenses and the accumulation of deficit and/or surplus balances by individual contractor. Under this concept, each contractor has repayment responsibility for the costs applicable to its M&I water deliveries and, if a deficit occurs, the individual contractor has continuing repayment responsibility for that deficit. This concept was codified by Public Law 99-546, which requires annual accountings of net income or deficit for each individual Project water contractor, as follows:

"The Secretary of the Interior shall include in each new or amended contract for the delivery of water from the Central Valley project provisions ensuring that any annual deficit (outstanding or hereafter arising) incurred by a Central Valley project water contractor in the payment of operation and maintenance cost of the Central Valley project is repaid by such contractor under terms of such new or amended contract . . (underlining added)

-- Cost of Service refers to the determination of annual water rates based on the Government's cost of providing M&I water to the individual contractor's designated delivery point. This includes recovery, within the authorized repayment period, of: (1) annual O&M costs, (2) interest costs, (3) M&I investment costs, and (4) any individual contractor deficit balances.

In accordance with the provisions of Public Law 99-546, the repayment period for the main Project water system facilities, referred to as the in-basin facilities, began in 1981 and ends in 2030. The repayment period commenced the year after the last major water storage facility, the New Melones Dam and Reservoir, was placed in service.

A separate repayment period of 1987-2036 has been established for the costs of the San Felipe Division facilities, also referred to as the out-of-basin facilities. The repayment period for the out-of-basin facilities commenced the year after these facilities were substantially completed. For repayment purposes, the Proposed Policy isolates the costs of the San Felipe Division out-of-basin facilities. The San Felipe Division contractors have sole repayment responsibility for the out-of-basin costs.

Under the Proposed Policy, annual M&I water rates are based on operating cost and capital cost pools, or components, and interest and deficit recovery rates, where applicable. The O&M cost components include the annual labor, supervision, materials, and other types of O&M expenses associated with each of the five operating cost components -- water marketing, storage, conveyance, conveyance pumping, and direct pumping. The capital cost components -- storage, conveyance, conveyance pumping, and direct pumping -- are associated with recovery of the costs of structures and facilities within the applicable in-basin and out-of-basin repayment periods.

A preliminary step in the determination of annual O&M and capital cost component rates is to accumulate the total pooled cost and the acre-feet of water deliveries applicable to each component. Once the costs and acre-feet applicable to each component have been determined, the basic methodology for computing annual water rates is to divide each component's pooled cost by its corresponding acre-feet of water deliveries.

-- For the O&M cast components, the annually determined rates are computed by dividing the pooled annual costs by the corresponding projected annual water deliveries for each component, respectively. Operating cost components are assigned to contractors on the basis of the services used to deliver their water supply. All water deliveries require water marketing services. While most contractors require storage services, several Project contractors operate and maintain the storage and conveyance facilities that provide their water service at their own expense. In those cases, the pooled O&M cost components are excluded from their water rates.

-- The in-basin capital cost components are determined by accumulating all M&I plant costs by component, as of the most recently completed fiscal year, and then dividing each component's costs by its total historical and projected acre-feet for the authorized repayment period of 1981-2030. The resultant component capital rates are then combined as applicable by individual contractor. The combined capital rate is then multiplied by the total quantity of water to be delivered to the contractor during the 1981-2030 repayment period, with the result being the capital cost allocation to the contractor. This allocation, less any repayment realized as of the end of the same fiscal year, is then divided by the present worth of remaining deliveries to be made during the repayment period, with the result being the individual capital rate for the then-current water year. The present worth of remaining deliveries concept is provided in the GLOSSARY on page 36.

-- The out-of-basin capital cost component is determined in the same manner as that described above for the in-basin capital cost components, only using the capital costs, repayment period, water deliveries, and interest rate applicable to the out-of-basin facilities.

-- The interest recovery rate is comprised of two elements: interest on unpaid plant investment, and interest on deficit balances, by individual contractor. All interest costs are computed annually on a compound basis. This component is described in detail starting on page 11.

-- Individual contractor deficit recovery rates are computed by dividing the contractor's accumulated deficit balance as of the end of the most recently completed fiscal year by the present worth of that contractor's projected deliveries over the remaining repayment period. The present worth of each contractor's projected deliveries is computed using each contractor's composite deficit interest rate.

Deficits or surpluses, as well as the updating of accumulated deficit or surplus balances, are determined each fiscal year. All M&I O&M costs are compiled and grouped into the components indicated above. Costs in each component are allocated to those contractors utilizing that component, based on each contractor's respective share of the total annual water deliveries for that component. Interest charges on O&M deficits and on unpaid capital investment are then added to the O&M costs, resulting in the total costs assigned to the individual contractor for the year.  Total costs applicable to each contractor are then compared with the corresponding revenues applicable to each contractor.  The result is either a net surplus or deficit for that fiscal year.   A hypothetical example of this process is shown below:

Revenues - Contractor A   $500,000
O&M Expenses - Contractor A    

Water Marketing






Conveyance Pumping


Direct Pumping


Total O&M

Interest Expenses - Contractor A 120,000  

Total Current Year Expenses


Net Surplus (Deficit) - Contractor A


Contractor revenues are applied first towards current year expenses -- O&M and interest expenses. Revenues in excess of current year expenses are then applied first to repaying allocated capital costs, and second to unpaid prior year O&M costs (i.e., deficits).

The total of the assigned O&M (including interest), capital, and deficit (if applicable) rate components constitutes the contractor's annual water rate. The applicable components and the makeup of each contractors 1993 water rate computed in accordance with the Proposed Policy is shown on Schedules A-2 and A-3 of the 1993 M&I Rate Book.

Description of Water Rate Components

A general description of each of the M&I water rate components, computational mechanics, and other specifics is provided below.

Water Marketing

The water marketing cost component includes the costs incurred for monitoring, administering and negotiating water service contracts, maintaining water delivery and payment records, accounting for the annual financial results for Project water operations, developing annual water rates, and related types of activities.

Dividing the total water marketing costs by the total projected water deliveries for the corresponding water year results in the average cost per acre-foot for this component.


The storage O&M cost and capital investment components represent the costs of project facilities associated with the collection and storage of Project water. These facilities consist primarily of the Project's dams and reservoirs, such as Shasta, Folsom and New Melones.

All contractors receiving storage services are assigned a Project-wide capital rate, except for the Foresthill Public Utility District (which has a fixed repayment obligation) and the San Felipe Division users whose storage capital rate includes an adjustment for the costs of the San Luis Pumping-Generating Plant. Because the San Luis Pumping-Generating Plant serves as a pumping-only facility for the San Felipe Division, the costs of the San Luis Pumping- Generating Plant are assigned to the San Felipe Division as direct pumping costs, rather than as storage costs.

Storage O&M costs include the project use energy costs associated with pumping water at the San Luis Pumping-Generating Plant, the Columbia-Mowry System, and the Folsom Pumping Plant. Similar to the treatment of storage capital costs, all storage contractors receive the same storage O&M rate, except for the San Felipe Division. The San Felipe rates include an adjustment for the costs of the San Luis Pumping-Generating Plant as described above.


The conveyance O&M and capital cost components include the costs associated with Project facilities designed and used for transporting water throughout the Project. Canals such as the Delta-Mendota, San Luis, and Friant-Kern Canals, are the primary type of facility included in this cost component.

All contractors receiving in-basin conveyance services, including those in the San Felipe Division, are assigned the same conveyance operating and capital rate components. The San Felipe Division contractors have an additional capital rate for the conveyance facilities which are located out-of-basin and used exclusively by the San Felipe contractors. The San Felipe Division contractors perform the O&M on the out-of-basin conveyance facilities.

Conveyance Pumping

The conveyance pumping O&M and capital cost components include the costs of the three main Project pumping facilities used to move M&I water through the Project; the Tracy Pumping Plant, the O'Neill Pumping-Generating Plant, and the Dos Amigos Pumping Plant. Separate O&M and capital rates are computed for each of the three pumping plants and those rates are assigned to contractors whose water is pumped through these pumping plants.

In addition to labor, supervision, and other typical O&M cost elements, conveyance pumping O&M expenses include project use energy costs. Project use energy costs are charged on the energy used to pump water at each of the pumping plants. The amount of energy required to pump an acre-foot of water varies at each of the three facilities because of the different lift requirement at each facility. The greater the lift requirement, the more energy required to pump each acre-foot of water and the more pumping O&M expenses associated with that acre-foot of water.

Total conveyance pumping costs are assigned to pumping plants based on each plant's prorata share of project use energy used. The per acre-foot rates calculated for each of the pumping facilities used by a contractor are totaled to determine each contractor's conveyance pumping O&M rate.

Separate conveyance pumping capital rates are calculated for each of the three pumping plants based on the recorded capital costs as of the end of the most recently completed fiscal year. A rate per acre-foot is calculated for each facility based on its total historic and projected deliveries during the 50-year repayment period. The rates for each of the main pumping facilities used by a contractor are totaled to determine the contractor's capital rate for conveyance pumping.

A portion of the Tracy Pumping Plant's capital costs and O&M expenses are assigned to the Friant-Kern Canal and Madera Canal contractors on the basis of the historical and projected deliveries to the Exchange contractors located in the Delta-Mendota Pool service area.

Direct Pumping

The direct pumping O&M and capital cost components are based on the costs associated with relift pumping plants which pump water exclusively for specific contractors. These facilities were constructed by Reclamation and are now operated and maintained by the local water districts whose water they pump. These facilities and the operating entities follow:

Pumping Plant Operator
Wintu Pumping Plant Bella Vista Water District
Contra Costa Canal Pumping Plants Contra Costa Water District
Ygnacio Pumping Plant Contra Costa Water District
Clayton Pumping Plant Contra Costa Water District
San Luis Relift Pumping Plants San Luis Water District
Westlands Relift Pumping Plants Westlands Water District
Pleasant Valley Pumping Plant Westlands Water District
Pacheco Pumping Plant Santa Clara Valley Water District
Coyote Pumping Plant Santa Clara Valley Water District

The direct pumping capital costs as of the end of the most recently completed fiscal year are allocated to the contractors using the facilities.  A per acre-foot rate is calculated for each plant based on the total of the historical and projected deliveries over the 50-year repayment period.

Because each pumping plant is operated by a local water district at its expense, the only project O&M costs to be recovered are the project use energy costs.  Project use energy costs are charged directly to the user of the direct pumping facility.


M&I is an interest-bearing function, and interest is computed annually on both the individual contractor's unpaid capital cost allocation and their accumulated deficit balances.

Annual interest on general (non-specific) plant investment is calculated using a composite interest rate for the Project.  The interest rate applicable to the unpaid plant investment balance during the 1949-1973 period is 2.5 percent.  The facilities placed in service after 1973 had higher authorized interest rates.  A composite interest rate is developed each year which weighs each of the authorized interest rates by the expenditures to date for the in-service facilities.  Since 1973, the composite interest rate for the in-basin facilities has gradually increased to a rate of 2.832 percent in 1991.  The composite interest rate is updated annually to reflect any additions to the Project plant in service accounts and their authorized interest rates.  Interest on the unpaid balance of the specific costs allocated to individual contractors is calculated using the authorized interest rate for the specific facilities.

Interest on individual contractor deficit balances is based on different interest rate criteria.   The deficit balance for an individual contractor refers to the accumulation of annual O&M and maintenance costs, including interest expenses, which exceeded the annual water service payments made by the contractor.  As explained below, interest on each contractor's cumulative deficit has been based on separate interest rate criteria applicable to three periods:  1949-1976, 1977-1985, and 1986-present. The specific rates applicable to each year's deficit are displayed on Exhibit 2 under the "Interest Rate" column. A brief discussion of the interest rates for each of the three periods follows:

-- The Project unpaid plant investment interest rate is applied to all operating deficits incurred during the 1949-1976 period. The rates used during this period were comprised of a specific rate of 2.5 percent for the period 1949-1973, which gradually increased to a composite rate of 2.654 percent in 1976. Use of the unpaid plant investment interest rates is consistent with Reclamation's practices and instructions during that period.

-- In 1977, new instructions were received which prescribed applying annual Project power repayment interest rates to future M&I deficits. Given this second interest rate criteria, a composite deficit interest rate was computed to reflect the weighing of the annual deficits and applicable interest rates.

-- In 1986, the 1977 instructions were superseded by the enactment of Public Law 99-546. Section 106 of that law provides for the application of an annually updated Federal interest rate to all annual deficits incurred by Project water contractors.  Annually, each contractor's composite deficit interest rate is updated for new O&M deficits incurred at the applicable Section 106 deficit interest rate. The composite deficit interest rates applicable to each contractor's O&M deficit as of September 30, 1991, are shown on Schedule 12A, page 1 of 3, of the 1993 M&I Rate Book.


Annually, deficits or surpluses by individual contractor are determined by comparing each contractor's total allocated costs with their respective revenues. A detailed description of how the deficits or surpluses are determined, as well as an explanation of how deficit recovery rates are calculated, was provided on page 8.

Deferred Interest Method

A potential inequity in the allocation of interest was identified during the early development of the Proposed Policy. This inequity stems from a disproportionate allocation of interest costs. An example of how this disproportionate interest allocation occurs follows.

-- If, in the first year of M&I water deliveries, only one contractor was taking water from a system ultimately designed for 50 contractors, all the plant costs of the M&I function and the repayment interest for that year would be allocated to the one user. The contractor would not be ultimately responsible for repaying all the capital costs, as the capital costs would be reallocated each year based upon the then-current contractors receiving water services. However, there is no retroactive adjustment of allocated interest expense. Accordingly, the contractor is forever burdened with the repayment obligation for the entire interest amount computed for the initial year. These interest costs together with assigned O&M costs result in increased deficits, as well as increased interest charges on those deficits.

The need for a method to equitably allocate historic interest costs during completion of the many features of the Project led to the development of the Deferred Interest Method. The Deferred Interest Method established the period 1949-1987 as the period during which inequitable plant allocations and interest computations occurred. As such, M&I plant costs, annual plant interest, O&M deficits, and deficit interest applicable to that period were recomputed under the Deferred Interest Method.

As shown on Exhibit 2, interest for the early project years, 1949 through 1987, under the Deferred Interest Method is $26 million less than the amount of interest originally computed and allocated to contractors. The Deferred Interest Method ensures recovery of the $26 million by amortizing these charges as an additional capital cost component to be repaid over the remaining Project repayment period. By doing this, it permits the reallocation of capital costs and the resultant computation of a substantially lower amount of interest as of 1987, while still providing or full recovery of the interest amount. This is accomplished by capitalizing the $26 million of deferred interest at the applicable interest composite interest rate (Exhibit 2), and including a deferred interest component in M&I rates to recover such amount.

Both the Deferred Interest Method and the original interest computation method yield essentially the same financial result to the U.S. Government. The difference between the two methods lies in the procedures for computing interest costs by contractor and in the timing and method for recovering such interest costs. The Deferred Interest Method erases the inequity in computing contractor annual interest for years prior to 1988, resulting in $26 million less interest computed through this period, and provides for recovery of the $26 million, with interest, through the capitalized Deferred Interest Method.

The Deferred Interest Method is the procedure utilized in the Proposed Policy.

Minimum M&I Water Rate

The M&I ratesetting policy will continue to honor the water rate provisions of existing long-term M&I water contracts even though some of these rates are less than the cost of service rates computed under the Proposed Policy. However, the Proposed Policy does not preclude contractors from voluntarily paying the computed O&M or cost of service rates.

Contractors with long-term contracts having water service rates in excess of computed cost of service rates will be required to continue paying these rates until the contract expires or is renewed. Upon renewal, the contract will provide for annual adjustments of the water rate to the higher of the annually computed cost of service rate or the minimum M&I water rate as described below.

The minimum Project M&I water rate shall be the higher of: (1) a rate of $15 per acre-foot, or (2) a rate equal to the O&M costs applicable to delivering Project M&I water to the contractor's designated point of delivery.

An example of the computation of a contractor's minimum water rate follows:

Water Marketing:    

Budgeted O&M Costs - 1993



Projected Water Deliveries - 1993


Cost Per Acre-foot

Storage O&M:    

Budgeted O&M Costs - 1993


Projected Water Deliveries - 1993


Cost Per Acre-foot

Conveyance O&M:    

Budgeted O&M Costs - 1993


Projected Water Deliveries - 1993


Cost Per Acre-foot


Total O&M Cost Per Acre-foot


** As the computed O&M rate is less than the $15 minimum rate, the rate applicable to the contractor in this situation would be the $15 rate.

All water revenues, including minimum M&I water rate amounts, will be accounted for by individual contractor and will be available to meet current and future repayment obligations applicable to the individual contractor.

Once the M&I function of the Project achieves an overall positive repayment status, the use of a minimum rate procedure will be suspended. In place of the minimum rate procedure, the minimum Project M&I rate will become the O&M rate, so long as the Project maintains a positive repayment status.

Once the Project is in a positive repayment status, a mechanism will be established for crediting contractors for payments they have made in excess of their allocated share of capital and operating costs. Such a mechanism may include reductions to water service bills, and other such credits as may be determined appropriate at that time.

Recovery of M&I Investment

The Proposed Policy recognizes the legal requirement of honoring the Project's existing long-term, fixed-rate water service contracts. However, honoring these contracts provides very little opportunity to adjust the M&I rates or increase the amount of M&I revenues. In the absence of authority to unilaterally increase the contract rates, M&I revenues do not begin to increase appreciably until 2005, when the first major group of fixed-rate contracts are subject to renewal. During the 1992 through 2004 period, the inability to generate sufficient revenues to keep pace with steadily rising O&M and interest costs will, in all probability, result in a continuing downward slide in the M&I financial position.

A graph (Figure 1) depicting the estimated revenues and interest expenses flows for the period 1990-2030 is provided on page 20. This Figure does not consider the impacts of potential early contract renewals under the provisions of Public Law 102-575. The Figure represents estimated revenues and interest expenses with contract renewals accomplished in accordance with existing contract provisions.

As shown in Figure 1:

-- Annual revenues rise gradually from $6 million in 1990 to approximately $22 million in 2005. This relatively gradual rise in revenues is attributable to a combination of factors, including a limited number of renewed contracts at cost of service rates, periodic adjustments of rates for contracts with rate adjustment clauses, gradual increases in annual water sales, and annually increasing water rates. While revenues gradually increase between 1990 and 2005, annual O&M deficits continue to increase during this period.

-- Annual revenues during the period 2006-2013 rise dramatically reflecting a major block of contract renewals during this period.

-- Increases in annual revenues after 2013 are due primarily to some increase in water sales and increased O&M costs which are assumed to escalate at an annual rate of five percent in the revenue analysis.

-- As contracts are renewed with cost of service rates, annual deficits quickly disappear and substantial annual surpluses occur. As interest charges decrease on outstanding O&M deficits and unpaid capital balances, greater net revenues become available for repayment. A sharp increase in revenues occurs during 2022 and 2024 due to the renewal of a block of contracts having a significant amount of M&I water deliveries.

Annual O&M. Annual O&M costs, annual interest expense related to the outstanding M&I capital investment and, where applicable, annual interest on the operating coat deficit.

Historical and Projected Water Deliveries. All paid water delivered and expected to be delivered by the plant in service facilities within the Project's repayment period. The time frame extends from the beginning of the first year in which water was delivered through the end of the repayment period.

In-Basin Facilities. The main project water storage and delivery system facilities located in the Central Valley Basin of California.

Isolated Facilities. Project constructed water storage and delivery facilities which are not operationally integrated with the main Project water system. For example, Project water developed by Sugar Pine Dam and Reservoir is all delivered to the local service area; none of that water is exported from the local area for delivery to other Project water users.

Long-Term Contractor. A contractor who's receiving water on a regular basis under a water service or repayment contract having a term of greater than 10 years.

Net Repayment. Accumulation of annual water service payments in excess of the amount required to cover the annual O&M and interest costs. The revenue available to reduce a contractor's deficit and capital investment balances.

Deficit. The accumulation of annual O&M and interest costs in excess of the total revenues received from the sale of water under existing water service contracts. The Project's M&I water supply account has a deficit balance, and the deficit has been increasing every year. The deficit has increased because revenues have not covered all the operating costs.

Out-of-Basin Facilities. The Project water system facilities located outside the Central Valley Basin of California, i.e., those Project facilities located in the San Felipe Division service.

Paid Water. All project water supplies scheduled for delivery to long-term water contractors for revenue producing purposes. Project water delivered for non-revenue producing purposes, such as water rights and mitigation, is excluded from paid water.

Present Worth. A financial term referring to the time value of money. The present worth concept recognizes that the interest earning capability of money makes $1 in the future worth less than $1 today. As an example, if $1 was deposited today at a 10 percent interest rate, it would be worth $1.10 in 1 year. Thus, $1 in 1 year would be worth something less than $1 today.

Present Worth of Future Deliveries. The same concept as indicated in the preceding Present Worth definition, only as applied to a stream of water deliveries rather than monetary payments. Similar to the concept that money earns interest, M&I costs must be repaid with interest; and hence, as $1 is worth more today than in the future, an acre-foot of water today is worth more than an acre-foot sold at the same price in the future. Because of this, the time value of future deliveries must be considered in determining capital and O&M deficit water rates required to repay these costs within the repayment period. The present value of future deliveries is computed by discounting such deliveries by the applicable interest rate over the remaining repayment period.

Projected Water Deliveries. All paid water expected to be delivered during the remainder of the repayment period.

Proposed Policy. For ease of reference, an abbreviated title for the full name of the M&I Component With Individual Contractor Deficit Ratesetting Method. The Proposed Policy is explained in this document.

Repayment Period. The time allowed for the recovery of the capital invested in a project. A 50-year repayment period has been established for the Project. For in-basin Project facilities, the repayment period runs from the beginning of fiscal year 1981 to the end of fiscal year 2030. The repayment period for the San Felipe Division out-of-basin facilities extends from the beginning of fiscal year 1987 to the end of fiscal year 2036.

Water Rate or Rate(s). As discussed throughout this document, general use of these terms refers to the cost of M&I water expressed on a cost per acre-foot basis. When other meanings are intended in the use of the words "rate" or "rates", such as in referring to an interest rate or rates, such clarifying words are provided in the text as appropriate.
