The United States and seven third-party defendants appeal the decision of the Court of Federal Claims holding that the methodology adopted by the Western Area Power Authority (“Western”) to refund excess revenues collected under energy sales contracts was unreasonable, and ordering Western to calculate the appropriate refund to which plaintiffs Southern California Edison (“SCE”) and Los Angeles Department of Water and Power (“LADWP”) were entitled. In addition, the third-party defendants contend that the Court of Federal Claims improperly exercised jurisdiction over them. We conclude that the Court of Federal Claims had jurisdiction over the third-party defendants, and thus affirm-in-part. However, because the Court of Federal Claims errеd in determining that Western’s refund methodology was unreasonable, we reverse-in-part.
BACKGROUND
In 1928, Congress passed legislation authorizing the construction of a dam and hydroelectric power plant at Boulder Canyon, located on the Colorado River at the Nevada/Arizona border. See Boulder Canyon Project Act (“BCPA”), Pub.L. No. 70-642, 45 Stat. 1057 (codified as amended at 43 U.S.C. §§ 617-617v (1994)). The dam was later named the Hoover Dam. In order to fund this mammoth construction project, Congress decided to take advantage of the revenue generating potential of the power plant. To this end, Congress granted the Secretary of the Interior (“Secretary”) the authority to enter into contracts for the sale of energy produced at the Hoover Dam, and required thеse contracts to generate sufficient revenue to ensure “payment of all expenses of operation and maintenance of said works [i.e., the dam and power plant] incurred by the United States, and the repayment, within fifty years from the date of completion of said works, of all amounts advanced [by the United States] for such works.” 43 U.S.C. § 617c(b).
The Boulder Canyon Project Adjustment Act (“Adjustment Act”), Pub.L. No. 76-756, 54 Stat. 774 (codified as amended at 43 U.S.C. §§ 618-618p (1994)), enacted twelve years later, specified additional details surrounding the sale of energy produced at the Hoover Dam, such as the allocation of revenues collected from ener
Pursuant to the Adjustment Act, the Secretary promulgated General Regulations (“Regulations”) governing contracts for the sale of energy generated at the Hoover Dam. These Regulations established two categories of energy — firm energy and secondary energy. See Regulations, art. 3. Firm energy was described a pre-defined minimum amount of energy that the Secretary reasonably expected the Hoover Dam to generate each year. See id. For example, in the first year of operation, the Regulations defined the firm energy as the first 4,330,000,000 kilowatt-hours generated at the site. See id. In each subsequent year, the amount of energy designated as firm energy decreased by 8,760,000 kilowatt-hours per year. See id. Over the fifty-year duration of the contracts, the total amount of firm energy was to be 205 billion kilowatt-hours. Secondary energy was defined as the amount of energy generated in any given year in excess of firm energy. See id. Unlike the firm energy, the yearly availability of secondary energy was speculative and depended upon the vicissitudes of the Colorado River’s hydrology. While the availability of secondary energy in any given year could not be predicted, the Secretary assumed, based upon expert analysis, that 40 billion kilowatt-hours of secondary energy would be produced over the contract period. See id.
Under the Regulations, the Secretary had the authority to set the rates for firm and secondary energy. See id., art. 6. These rate-setting determinations were to be made at five-year intervals, subject to annual adjustments to take into account the actual expenditures and costs incurred each year. See id., art. 14. In making rate-setting determinations, the Secretary assumed that the full amount of firm energy would be generated each year, and that over the fifty-year term of the contracts, the еntire 40 billion kilowatt-hours of secondary energy would be available for sale. See id., art. 3. Based on these output assumptions, rates were set so as to ensure that the revenues collected from the sale of energy would “be sufficient, but not more than sufficient” to cover the costs associated with the construction and operation of the Hoover Dam and the appurtenant power plant. Id., art. 6.
Aside from the revenue requirements, a number of additional requirements had to be satisfied in setting energy rates. For example, the Regulations established a fixed mathematical relationship between the rates for firm and secondary energy, and a 0.2 mill per kilowatt-hour minimum charge for secondary energy. See id., art. 8. Also, the Regulations required uniformity of rates among all customers, that is, the rate for firm energy was required to be the same for all purchasers of firm energy, and the rate for secondary energy was required to be the same for all purchasers of secondary energy.
Finally, at the end of the fifty-year contract period, the Regulations provided for a final accounting of project costs and revenues collected. See id., art. 14. If revenues collected did not exactly offset the costs associated with the project, the Regulations mandated that “adjustments shall be made, through refunds or collections as the Secretary may find necessary to achieve consummation of the principle that the revenues shall be sufficient but not more than sufficiеnt to” cover project costs. Id., art. 14(e).
Between 1941 and 1960, all of the parties to this litigation entered into contracts with the United States for the purchase of energy generated at the Hoover Dam.
Following the mandate of the Regulations, the Secretary set the rates for energy at five-year intervals, and made annual adjustments to account for fluctuations in project operation and maintenance costs. In making these determinations, the Secretary relied on the output assumptions for firm and secondary power embodied in the Regulations. See id., art. 3. In other words, the Secretary assumed that in each year, revenues for thе entire predicted amount of firm energy would be generated. Additionally, the Secretary assumed that over the fifty-year duration of the contracts, revenues for the entire 40 billion kilowatt-hours would be generated. During the first two decades of operation, the output assumptions proved remarkably accurate, and thus, the revenues collected kept pace with the project expenses. However, between 1954 and 1983, the amount of secondary energy generated was well below expectations, with no secondary energy at all produced in twenty-five of those twenty-nine years. By 1982, only 17.5 billion kilowatt-hours of the estimated 40 billion kilowatt-hours of secondary energy had been produced. Recognizing that the project would experience significant shortfalls if prevailing diminished water-flow conditions continued, Western
Beginning in 1983, however, water flow of the Colorado River watershed significantly changed. Rain and runoff from excessive snowfall resulted in widespread flooding in the western states. Consequently, the energy produced at the Hoover Dam increased dramatically, far surpassing the revised prеdictions for secondary energy output. This turned an expected shortfall into a large surplus. In fact, in 1986, one year prior to the expiration of the contract, the entire cost of the project had been met, and at the end of the contract period, Western had collected a $25 million surplus. Thus, pursuant to Article 14(e) of the Regulations, Western was required to make “adjustments” so that the revenues collected were not “more than sufficient” to cover the project costs.
Western considered a number of methodologies for allocating the refund to the various customers, including methodologies taking into consideration revenue generated from secondary energy purchases. Ultimately, Western decided to refund the excess to its customers based only on each customers’ firm energy entitlement percentage as defined by Article 4(a) of the Regulations. Refund checks reflecting this methodology were distributed, and were accepted and negotiated by all customers.
In response to this impasse, the United States filed suit in the United States District Court for the District of Nevada on February 14, 1996, seeking a judicial declaration upholding the reasonableness of Western’s refund methodology. A few days later, SCE and LADWP filed suit against the government in the Court of Federal Claims, alleging breach of contract. The government then joined the seven other customers as third-party defendants, so that it could seek reimbursement from them for any amounts paid to SCE and LADWP. The third-party defendаnts moved for dismissal of the contingent claims against them, alleging that the Court of Federal Claims lacked subject matter jurisdiction over these claims. This motion was rejected. See Southern Cal. Edison Co. v. United States,
All parties filed motions for summary judgment following discovery. SCE and LADWP argued that the allocation method adopted by Western breached their contracts and violated the Regulations, and that Western’s actions were not entitled to judicial deference. The government, on the other hand, argued that the allocation method represented a reasonable interpretation of unclear regulatory language, and should be given deference by the reviewing court. The third-party defendants supported the government’s argument for deference, and also argued that SCE and LADWP should be barred by laches, equitable estoppel, or the statute of limitations from asserting their claims. The Court of Federal Claims determined that while a reasonable allocation method would have been entitled to deference, the particular scheme adopted by Western was an unreasonable construction of the Regulations. See Southern Cal. Edison Co. v. United States,
DISCUSSION
A.
Before reaching the merits of this appeal, we must determine whether the decision of the Court of Federal Claims, in which the court remanded this case to Western for a calculation of damages, is final and appealable. See 28 U.S.C. § 1295(a)(3) (1994); see also Palmer v. Barram,
We must also determine whether the Court of Federal Claims properly exercised jurisdiction over the contingent claims filed by the government against the third-party defendants, an issue we review de novo. See Shearin v. United States,
Under § 114(b), the Court of Federal Claims has jurisdiction over contingent claims asserted by the government against third parties “for the recovery of money ... paid by the United States in respect of the transaction or matter which constitutes the subject matter of such case.” This section provides for jurisdiction in situations where the government is seeking the recovery of a sum of money disbursed to the wrong party. See Maryland Cas. Co. v. United States,
The third-party defendants claim that because each customer has a separate contract with the government, the contingent suits against them do not constitute the same “subject matter” as the suits filed by SCE and LAJDWP, and thus are outside the scope of § 114(b). In support of their position, the third-party defendants point to Oliver-Finnie Co. v. United States,
The third party defendants also assert that the government’s contingent claim is time-barred under § 2415. This argument is specious. Section 2415 specifically provides that the six-year statute of limitations does not apply to the government when it is seeking to recover improperly disbursed funds. See § 2415(f) (“[T]his section shall not prevent the assertion ... of any claim of the United States ... against ... a third party, that arises out of a transaction or occurrence that is the subject matter of the opposing party’s claim....”). Thus, the Court of Federal Claims properly exercised jurisdiction over the third-party defendants.
B.
The primary dispute in this case centers around the refund methodology adopted by Western to distributе surplus funds that it held at the end of the contract period. The regulatory basis for this refund comes from Article 14(e), which reads: “[Ajdjustments shall be made, through refunds or collections as the Secretary may find necessary to achieve consummation of the principle that the revenues shall be sufficient but not more than sufficient to” cover the construction, operating, and maintenance costs of the Hoover Dam project. Western, after considering various refund methodologies, decided that the refunds should be based on the percentage of firm power each contractor was entitled to purchase under the contracts. We must first determine the proper standard of review to apply to this determination. Thus, we must decide whether the Court of Federal Claims was correct in reviewing this regulatory interpretation only for reasonableness, or whether this interpretation must be reviewed independently and without deference.
Courts are, in certain circumstances, required to give deference to a regulation that embodies an agency’s reasonable interpretation of a statute under its administrative authority. See Chevron, U.S.A, Inc. v. Natural Resources Defense Council, Inc.,
While regulatory interpretations are generally afforded substantial deference by reviewing courts, the regulation at issue in this case is incorporated by reference into contracts entered into between the government and several private energy customers. According to SCE and LADWP, it is inappropriate to give deference to an agency’s interpretation of a contractual provision when the government is itself a party to the contract. This argument is not without force. When a party enters into a contract with the government, that party should reasonably expect to be on equal legal footing with the government should a dispute over the contract arise. If courts were generally to adopt a principle of deference to an agency’s contract interpretation, such deference could lead the courts to endorse self-serving post-hoc reinterpretations of contracts that an agency might offer in the context of a litigation. See National Fuel Gas Supply v. Federal Energy Reg. Comm’n,
First, despite the fact that the government is a party to these contracts, it had no economic stake in the excess revenue that was to be distributed. Western’s only function under the Regulations was to adopt a methodology to refund the over-collection to the energy customers. In such a circumstance, there was no motivation for Western to adopt a self-interested regulatory interpretatiоn because under any refund allocation method, all excess revenues would be distributed from its coffers to the customers. In other words, the agency was acting as a neutral arbiter resolving the customers’ rights to the over-collected funds, rather than as an interested party to a contract. Because Western had no interest in the particular methodology adopted, the primary rationale against giving deference to an agency’s contract interpretations is diffused. See National Fuel,
This holding is not inconsistent with prior cases from this court which have held that a de novo standard of review is appropriate for matters of regulatory interpretation when regulations are incorporated into contracts. See United States v. Boeing Co.,
Having determined that the agency’s refund allocation method is entitled to deference, we turn to the question of its reasonableness. As described above, at the end of the fifty-year contract period, Western was faced with a $25 million surplus, which it was required to refund to the energy customers. See Regulations, art. 14(e). After considering several alternatives, Western decided to refund the excess revenue to the firm energy customers in proportion to each customer’s yearly allotment of firm energy. Western justified this decision on several grounds. First, Western noted that throughout the fifty-year duration of the contracts, the adjustments that were made to account for fluctuations in annual operating costs were accomplished through collections from or refunds to firm energy customers only. Western believed that it would be reasonable to follow a consistent methodology for the final adjustment. In addition, any revenue shortfall that was experienced at the end of the contract period would have been borne by the firm energy customers alone,
The Court of Federal Claims determined, however, that Western’s methodology was unreasonable. According to the court, Western’s refund methodology was improper because it failed to satisfy the rate determination precepts set forth in the Regulations. See id., arts. 6-8. Because Article 14 refers to “adjustments to energy rates,” the court reasoned that adjustments must be, in effect, retroactive rate-settings that maintain the fixed relationship between firm and secondary energy rates. See id., art. 8. By refunding money only to the firm energy customers, Western effectively lowered firm energy rates while leaving secondary energy rates the same. In the court’s judgment, this violated Article 8, rendering the refund methodology unreasonable.
While the interpretation by the Court of Federal Claims represents a reasonable reading of the Regulations, we cannot say that Western’s alternative interpretation was unreasonable. The regulatory language expressly grants broad discretion to the Secretary. See id., art. 14(e) (“[A]d-justments shall be made, through refunds or collections as the Secretary may find necessary ....”) (emphasis added). Consistent with this grant of discretion, the Regulations do not include specific guidance regarding the details of the refund methodology to be adopted. This regulatory silence supports the conclusion that the Secretary was to have wide latitude in devising the details of the refund methodology, so long as it was consistent with the purpose and wording of the Regulations. See Thomas Jefferson Univ.,
Western’s decision to base the refund only on the firm energy allotments found in Article 4(a) was within the broad discretion granted under this regulatory scheme. As described above, throughout the course of these contracts, the periodic adjustments required under Article 14 to ensure sufficient annual revenue were made by collections from or refunds to firm energy customers only. It was reasonable for Western to base the final adjustment under Article 14(e) on a similar scheme. Also, because any revenue shortfall that would have occurred at thе end of the contract period would have been covered by the firm energy customers only, it was reasonable to refund the excess revenues to them exclusively as well.
Western’s interpretation also appropriately reflects other fundamental differences between firm and secondary energy purchasers. Firm energy customers were required under the contracts to purchase a fixed quantity of energy each year. Thus, revenues generated from firm energy customers guaranteed the payments of the project’s costs. Secondary energy customers were not required to purchase any energy under the contracts. Rather, they were granted options to purchase secondary energy at rates that were at a fraction of the rates for firm energy. Although revenues generated from the sale of secondary energy made a modest contribution to the overall project costs, firm energy purchasers alone assumed the financial risk of the project. Western’s decision to refund the excess revenues only to firm energy customers is consistent with the allocation of risk between the firm and secondary energy customers.
The trial court’s primary rationale for faulting Western’s methodology was its failure to satisfy the rate-setting precepts of Articles 6 through 8. However, this does not render Western’s methodology unreasonable. First, the plain language of Article 14(e) does not require the interpretation adopted by thе trial court. While Article 14 refers to “adjustments to rates,” there is no express requirement that these adjustments comply with the rate-setting requirements found elsewhere in the Regulations. In fact, such a requirement would seem particularly inappropriate with
The correctness of this conclusion is underscored by the difficulty of implementing such a retroactive rate-setting determination. Article 14(e) clearly contemplates an adjustment that reconciles project costs with collected revenues over the entire fifty-year contract term. To develop a refund methodology that would retroactively adjust rates over this entire contract term would be an extremely complex undertaking. We will not presume, based simply оn the reference in Article 14 to “adjustment to rates,” that the Regulations require such a complex undertaking. SCE and LADWP contend that the appropriate time period to consider is not the entire fifty-year term, but only the final four years of the contract. While this would certainly simplify the determination, it has no support in the Regulations and thus must be rejected.
Finally, as described above, adjustments throughout the course of the contract were made with respect to firm energy customers alone, and any shortfall at the end of the contract period would have been covered by the firm energy customers alone. Taken to its logical extreme, these adjustments would be unreasonable under the trial court’s analysis because they would also violate the rate-setting precepts, particularly the requirement of Article 8 to maintain a fixed relationship between firm and secondary energy rates. However, these adjustments are clearly proper under the Regulations. It would be anomalous to suggest that these adjustments, which do not follow Article 8, are permissible, but Western’s refund methodology is not. Therefore, we hold that Western’s refund methodology represents a reasonable interpretation of the Regulations and must be given effect.
C.
The third-party defendants assert a number of other defenses against SCE’s and LADWP’s claims. They contend that SCE and LADWP should be barred from asserting their claims against the government by the one-year statute of limitations found in the Hoover Power Plаnt Act, 43 U.S.C. § 619a(h)(l) (1994). In addition, they argue that SCE’s and LADWP’s claims should be barred by equitable es-toppel and laches. Because we determine that Western’s refund methodology was reasonable, and thus entitled to finality, we need not address these additional defenses.
CONCLUSION
We affirm the decision of the Court of Federal Claims to exercise jurisdiction over the third-party defendants. However, because the Court of Federal Claims failed to give deference to the reasonable regulatory interpretation of Western, we reverse that portion of the court’s determination, and hold that Western’s refund methodology was entitled to finality.
COSTS
Each party shall bear its own costs.
