Justice O’Connor
delivered the opinion of the Court.
Federal law vests in the Secretary of Agriculture the authority to make emergency loans to farmers who suffer economic losses as a result of a natural disaster. See Consolidated Farm and Rural Development Act (Act), §§321-330, 75 Stat. 311, as amended, 7 U. S. C. §§1961-1971. [928] Pursuant to an agency rule, the Secretary required loan applicants suffering from disasters occurring between December 26, 1972, and April 20, 1973, to file their applications by April 2, 1974. 39 Fed. Reg. 7569 (1974) (later codified at 7 CFR § 1832.82(a) (1975)). That rule embodied a statutory command to keep the loan program open at least until that date. Pub. L. 93-237, 87 Stat. 1025. The question presented is whether a federal court has the remedial authority to reopen this long-terminated loan program on the basis of its finding that the Secretary, in alleged violation of another rule, failed adequately to notify affected farmers of the program’s availability and terms.

In early April 1973 torrential rams struck 13 counties m the northern part of Florida. Initial estimates, which were later sharply reduced, projected that resulting crop and property losses would be in excess of $3 million. In light of the scope of these anticipated losses, on May 26, 1973, President Nixon declared the region a major disaster area. 38 Fed. Reg. 14800 (1973). See Disaster Relief Act of 1970, Pub. L. 91-606, 84 Stat. 1744 (repealed or transferred 1974). As a result of this declaration, the Secretary of Agriculture came under a statutory obligation to “make loans” to qualifying individuals in the region. 7 U. S. C. § 1961(b) (1970 ed., Supp. III).
At the time of the declaration, the federal disaster relief program, like much of the rest of the Federal Government, had become embroiled in a budgetary dispute between the Executive and Legislative Branches. In 1972, Congress had passed Pub. L. 92-385, 86 Stat. 554, which authorized emergency loans under terms far more generous than those available under later versions of the Act. Under the 1972 law as implemented by the Secretary, loans carried a 1% interest rate and were not conditioned upon the unavailability of alternative sources of credit. In addition, the Secretary was [929] directed to forgive outright up to $5,000 of the principal of the loan. On December 27, 1972, as part of a larger, administrationwide effort to control what were viewed as excessive congressional appropriations, the Secretary directed that regional Farmers Home Administration (FmHA) officials effectively cease processing loan applications. See generally Berends v. Butz, 357 F. Supp. 143 (Minn. 1973); Impoundment of Appropriated Funds by the President: Joint Hearings before the Ad Hoc Subcommittee on Impoundment of Funds of the Senate Committee on Government Operations of the Senate Committee on the Judiciary, 93d Cong., 1st Sess., 532 (1973). Aware that the “forgiveness features and low interest rates provided for by Public Law 92-385” had contributed to the unilateral executive decision to curtail the program, Congress attempted to resolve the crisis by repealing those provisions. S. Rep. No. 93-85, p. 1 (1973). Public Law 93-24, 87 Stat. 24, which became effective on April 20, 1973, set the interest rate on emergency loans at 5%, limited the availability of loans to those unable to obtain credit from other sources, and eliminated entirely the provision that had previously allowed for cancellation of a portion of the principal. A grandfather clause provided that the terms of the earlier act, Pub. L. 92-385, would remain applicable to disasters designated between January 1 and December 27, 1972.
Left unclear, however, was the status of disasters occurring during the 4-month period between December 27, 1972, and April 20,1973, the effective date of Pub. L. 93-24. Congress resolved this uncertainty by passing Pub. L. 93-237, the provision at the center of this case. Section 4 of the new Act provided that, “[notwithstanding the provisions of Public Law 93-24,” loans “with respect to natural disasters which occurred” during this interim period would be governed by the more generous terms of Pub. L. 92-385. In addition, § 10(c) provided that the deadline for applying for a loan would be extended 90 days beyond the date of the enactment [930] of Pub. L. 93-237. This 90-day extension supplanted the established regulatory policy of the Secretary to accept loan applications for crop losses only if filed within nine months of the formal disaster declaration. (For physical losses the deadline was 60 days.) According to the Conference Report, the purpose of the extension was to make sure that the FmHA’s “administratively set deadlines” took into account the confusion among farmers concerning the numerous changes in federal disaster relief law in the recent past. S. Conf. Rep. No. 93-363, p. 6 (1973). The bill was signed into law on January 2,1974. Thus, the congressionally mandated 90-day period for loans under Pub. L. 93-237 expired on April 2, 1974.
The Florida flood coincided with this period of confusion in the administration of federal disaster relief. Between May 26, 1973 (the date the disaster was declared), and January 2, 1974 (the date Pub. L. 93-237 became law), the loan program was administered pursuant to the terms of Pub. L. 93-24. Accordingly, during this initial loan period, farmers had nine months, or until February 26,1974, to submit applications for emergency loans. At the time of the May 26, 1973, Presidential disaster declaration, and throughout the initial loan period, FmHA rules required the agency to follow certain procedures designed to notify potential borrowers of the availability of disaster relief. 7 CFR § 1832.3(a)(1) (1973). In addition to a general obligation to “make such public announcements as appear appropriate,” the regulations required the FmHA County Supervisor to inform various local officials and “agricultural lenders” of “the assistance available under [the] program.” Ibid,.1 It is undisputed that during the initial loan period no applications were filed.
[931] On February 15, 1974, approximately six weeks after the enactment of Pub. L. 93-237, the FmHA issued instructions to its staff concerning the implementation of the new emergency loan program. App. to Pet. for Cert. 48a. Shortly thereafter, the Secretary published these instructions without material change in the Federal Register.2 39 Fed. Reg. 7569 (1974) (later codified at 7 CFR §§ 1832.81-1832.92 (1975)). The Federal Register publication set out in detail the terms and conditions of the new program, including the 1% interest rate, the $5,000 forgiveness provision, and the absence of any requirement that the applicant demonstrate the unavailability of other credit. 39 Fed. Reg. 7571 (1974). The regulation also specified that “the termination date for acceptance of applications . . . will be April 2, 1974.” Id., at 7570.
Also included in the staff instructions were directions that “State Directors and County Supervisors . . . inform the news media, including newspapers, radio, and television in the affected counties of the provisions of P. L. 93-237.” App. to Pet. for Cert. 49a (later published as § 1832.82(a) of the “Special Emergency Loan Policies . . . Implementing Applicable Provisions of Public Law 93-237,” 39 Fed. Reg. 7569 (1974)). Attached to the instructions was a suggested news [932] release.3 App. to Pet. for Cert. 50a-51a. The release explained that farmers who had not yet received an emergency loan could apply for such a loan at the local FmHA office. Although not setting out the details of the new program, the model release did state that “loan applications will be taken under the terms of a new law (P. L. 93-237) enacted January 2, 1974.” Id., at 51a. Consistent with these instructions, the State FmHA director forwarded the sample news release to local agency offices. Those offices in turn sent copies to the local media, and, on at least two occasions, the releases were carried in newspapers in the north Florida disaster area. Record, Defendants’ Exhibits 10-12. During this second loan period, that is, the period between the enactment of Pub. L. 93-237 and the expiration of the 90-day deadline on April 2, 1974, no more than four farmers from the Florida disaster area applied for emergency loans.
On August 19, 1976, respondent Payne, a north Florida farmer, instituted the present action in the United States District Court for the Middle District of Florida. Although he had received actual notice of the special 1974 emergency loan program, he sought to represent a class of approximately 2,500 farmers who had been eligible for loans under that program but, because of lack of notice, had not been aware of their eligibility. Contending that the FmHA’s failure to publicize the program more fully violated the agency’s own regulations and deprived them of property without due process of law, respondents sought an injunction directing the FmHA to reopen the loan program under the terms prevailing during the period “up to and including April 2, 1974.” Complaint 6.
The District Court certified the class and granted the requested relief.4 In a variety of different ways, the court [933] found, the FmHA had failed to give adequate notice of the availability of loans. Most of the notice deficiencies specifically found by the court occurred during the initial loan period. It found, for example, that a number of farmers had left a June 1973 meeting with the incorrect impression that they were ineligible for loans, that FmHA officials knew of this misimpression, and that they failed to correct it. The court also found that press releases describing the terms of both the initial and new loan programs were incomplete. Finally, the court determined that, in violation of the specific requirements of 7 CFR § 1832.3(a)(1) (1973), the FmHA had failed to notify various state and county officials of the availability of emergency loans. The District Court did not allude to the specific notice requirements promulgated by the agency in connection with the implementation of Pub. L. 93-237. See 39 Fed. Reg. 7569 (1974) (§ 1832.82(a)). Apparently assuming, however, that the earlier notice requirements contained in 7 CFR § 1832.3(a)(1) (1973) continued to apply during the new loan period, the court held that the agency’s failure to adhere to these requirements required it to reopen the new loan program for a 60-day period extending from April 15, 1981, to June 15, 1981. In particular, the court premised the remedy on the FmHA’s failure “to make such public announcements as appear appropriate.” Ibid.
The Court of Appeals for the Eleventh Circuit affirmed, but on different grounds. Payne v. Block, 714 F. 2d 1510 (1983). It accepted the District Court’s various findings concerning the FmHA’s failure to comply with the notice requirements set out in 7 CFR § 1832.3(a)(1) (1973). Those findings, however, “pertain[ed] only peripherally” to its decision to affirm. 714 F. 2d, at 1519. Regardless of any violations of 7 CFR § 1832.3(a)(1), the court concluded, the FmHA had failed to comply with its self-imposed obligation to notify the [934] public of the new loan program. The agency had announced in the Federal Register that it would “inform the news media ... of the provisions of P. L. 93-237.” 39 Fed. Reg. 7570 (1974) (§ 1832.82(a)). This it had not done, the court believed, because the news releases announcing the new loan program had failed to explain its generous terms. In view of the established proposition that agencies are duty bound to adhere to their own procedures, the court held, the most appropriate remedy for the violation was an injunction directing the agency to reopen the loan program. In reaching this conclusion, the Court of Appeals rejected the Government’s argument that the April 2, 1974, application deadline was required by an Act of Congress and, therefore, beyond the authority of the District Court to expand. In the court’s view, Pub. L. 93-237 had merely required the FmHA to extend its administratively set deadline for 90 days. Nothing in the Act, however, divested the agency of discretion to extend it further.
The Secretary sought review in this Court, and we granted the petition for certiorari, vacated the judgment below, and remanded for reconsideration in light of our decision in Heckler v. Community Health Services of Crawford County, Inc., 467 U. S. 51 (1984). Block v. Payne, 469 U. S. 807 (1984). In Community Health Services, the Court held that, even assuming that principles of equitable estoppel ever applied against the Government, “a private party surely cannot prevail [on that theory] without at least demonstrating that the traditional elements of estoppel are present.” 467 U. S., at 61. The Court of Appeals, observing that petitioners’ liability was premised not on a theory of equitable estoppel but on the agency’s failure to follow its own regulations, adhered to its prior views and reinstated its decision. Block v. Payne, 751 F. 2d 1191 (1985).
Because the decision below exposes the Federal Government to substantial potential liability and because its reasoning implicates important questions about a federal court’s [935] remedial powers, we again granted certiorari. Block v. Payne, 474 U. S. 815 (1985). We now reverse.
1 — 1 1 — 1
The Secretary s principal argument in this Court is that the remedy granted below shares all of the essential characteristics of an equitable estoppel against the Government and, accordingly, should be analyzed on those terms. We acknowledge that the practical effect of the injunction requiring the reopening of the loan program is to estop the FmHA from relying on the validly promulgated regulatory deadline as a basis for refusing to process further loan applications.5 And we readily agree that, had respondents sought relief on an equitable estoppel theory, they could not prevail. As we observed only recently, even assuming that the Government is ever subject to estoppel, a “private party surely cannot prevail without at least demonstrating that the traditional elements of an estoppel are present.” Heckler v. Community Health Services of Crawford County, Inc., 467 U. S., at 61. An essential element of any estoppel is detrimental reliance on the adverse party’s misrepresentations, id., at 69 (citing 3 J. Pomeroy, Equity Jurisprudence § 805, p. 192 (S. Symons ed. 1941)); and neither the named plaintiffs, much less the 2,500 members of the class they represent, have sought to demonstrate such reliance. Moreover, the only misconduct specifically found by the District Court was the failure to give effective notice of information that, at least with respect to the second loan period, was concededly published in the Federal Register. Our cases leave no doubt that “failure to fully publicize the rights . . . accorded” by an Act of Congress does not “give rise to an estoppel against the Government.” INS [936] v. Hibi, 414 U. S. 5, 8-9 (1973) (per curiam). See also Heckler v. Community Health Services of Crawford County, Inc., supra, at 63 (“[T]hose who deal with the Government are expected to know the law”); Federal Crop Ins. Corp. v. Merrill, 332 U. S. 380, 384 (1947).
As the Court of Appeals correctly observed, however, respondents’ inability to satisfy the stringent requirements of common-law estoppel does not independently decide the case. Indeed, beginning with their initial complaint and throughout the course of the litigation, respondents have never sought to rely on estoppel as a basis for recovery. Their theory instead, and the theory on which the lower courts granted the injunction, is that the Administrative Procedure Act (APA), 5 U. S. C. § 551 et seq., authorizes this kind of relief to remedy the FmHA’s alleged failure to comply with its duly promulgated notice regulations. It may well be that some of the same concerns that limit the application of equitable estoppel against the Government bear on the appropriateness of awarding other remedies that have a close substantive resemblance to an estoppel. We reject, however, petitioners’ suggestion that any remedy that can be analogized to an equitable estoppel is necessarily invalid, regardless of the source of the cause of action, unless the plaintiff succeeds in proving all the elements of common-law estoppel. Cf. Honda v. Clark, 386 U. S. 484, 494-495 (1967). Indeed, any other rule has the potential for divesting the courts of the remedial authority specifically envisioned by Congress under the APA. If, for example, a farmer had filed a loan application prior to the expiration of the loan deadline and a court determined that the denial of the application after the deadline’s expiration was “arbitrary, capricious [and] not in accordance with law,” 5 U. S. C. §706(2)(A), the appropriate remedy under the APA would be to direct that the application be granted or reconsidered. Although this would, in a sense, estop the Government from applying the deadline, we have never suggested that the applicant would be under an [937] obligation to satisfy the requirements of proving an equitable estoppel to obtain the relief specifically available under the APA.
The question before us then is not whether the Secretary should be estopped from applying the deadline, but whether the relief afforded by the District Court was appropriate under the APA. Respondents contend that the notice regulations, having been promulgated pursuant to the Secretary’s delegated rulemaking authority, had the force and effect of law and therefore were binding on the agency. To remedy this noncompliance, they suggest, the District Court had the authority under 5 U. S. C. § 706 to “compe[l] ‘action unlawfully withheld’ [notice] and ‘set aside agency action’ [application of the deadline] found to be ‘without observance of procedures required by law.’” Brief for Respondents 21 (quoting 5 U. S. C. §706) (bracketed material in original).
To prevail on this theory, respondents must clear at least three substantial hurdles. At the outset, not all agency publications are of binding force, Schweiker v. Hansen, 450 U. S. 785, 789 (1981); and it remains to be shown that the notice provisions, which began life as unpublished staff instructions, are the kind of agency law the violation of which is remediable at all. Second, an agency’s power is no greater than that delegated to it by Congress. Thus, even assuming that Pub. L. 93-237 left the Secretary some discretion to extend the 90-day deadline beyond April 2, 1974, it would hardly be an abuse of that discretion to refuse to do so many years after the disaster had receded if such an extension would be inconsistent with the intent of Congress. Finally, the “agency action” respondents seek to have set aside is the “application of the deadline.” Yet, with the exception of respondent Payne, who clearly has no standing,6 there is no [938] allegation that any member of the class has ever applied for a loan. Although the APA includes “failure to act” in its definition of reviewable agency action, 5 U. S. C. § 551(13), it is far from clear that relief under the APA is appropriate when the allegedly aggrieved party has failed entirely to present its claim to the agency. Cf. Mathews v. Eldridge, 424 U. S. 319, 328 (1976).
We need not, however, definitively resolve any of these issues. Nor need we confront the Secretary’s broader contention that it is in all instances inappropriate for a court, reviewing for agency compliance with the APA, to set aside one validly promulgated regulation to remedy an alleged violation of another entirely independent one. An essential predicate of the relief granted below is that the FmHA in fact failed to comply with its own rules. As we now explain, the Court of Appeals’ conclusion that the FmHA violated its self-imposed obligation to give notice of the loan program is insupportable.
The Court of Appeals relied exclusively on the FmHA’s purported violation of § 1832.82(a), the'new notice provision, to uphold the injunction directing the Secretary to reopen the loan program. Although the agency did issue press releases, the court reasoned, its failure to describe the generous terms of the new program breached its regulatory obligation to “‘inform the news media ... of the provisions of P. L. No. 93-237.’” 714 F. 2d, at 1520, quoting 39 Fed. Reg. 7570 (1974) (emphasis supplied by Court of Appeals).
This reasoning is demonstrably incorrect. Public Law 93-237 itself said nothing at all about the availability of a reduced interest rate, the possibility of partial forgiveness of the loan principal, or the elimination of the requirement that credit be unavailable from other sources. It merely stated that “[notwithstanding the provisions of Public Law 93-24,” loans with respect to disasters occurring prior to April 20, 1973, would [939] be administered under Pub. L. 92-385. Thus, the statement in the news release that “loan applications will be taken under the terms of a new law (P. L. 93-237) enacted January 2, 1974,” though not a model of clarity, was no less informative than were the “provisions” of the Act the release was endeavoring to describe. App. to Pet. for Cert. 51a; 7 CFR § 1832.82(a) (1975).
Moreover, the Court of Appeals’ holding runs roughshod over the established proposition that an agency’s construction of its own regulations is entitled to substantial deference. United States v. Larionoff, 431 U. S. 864, 872 (1977); Udall v. Tallman, 380 U. S. 1, 16-17 (1965). The publicity directive that was later codified at 7 CFR § 1832.82(a) (1975) was originally issued as a staff instruction designed to describe the procedures for implementing Pub. L. 93-237. App. to Pet. for Cert. 48a-49a. Accompanying the instruction was a sample press release identical in all pertinent respects to those sent to the media in the area of the Florida disaster. Id., at 50a-51a. Because the suggested release obviously reflected the agency’s contemporaneous understanding of the scope of the publicity directive, it is logically untenable to suggest that the agency violated the directive by issuing press releases modeled explicitly on the sample.
The Court of Appeals specifically disclaimed any reliance on 7 CFR § 1832.3(a)(1) (1973), the Secretary’s previous publicity directive, to support its affirmance of the District Court’s judgment. As they are entitled to do, however, respondents now defend that judgment on the alternative theory that the agency’s violation of this earlier notice provision warranted the remedy of an injunction reopening the loan program. We find this theory no more supportable than that relied on by the Court of Appeals. As an initial matter, any violations of this regulation that occurred during the first loan period are plainly irrelevant. Starting with their complaint, and throughout the course of this lengthy litigation, respondents have sought to have the loan program reopened [940] under the more generous terms available under Pub. L. 93-237: And such was the relief granted by the District Court. App. to Pet. for Cert. 45a. As a simple matter of causation, any failure to inform respondents about the old loan program cannot support the remedy of requiring the FmHA to process loan applications under the “terms and benefits” available under the new one. Ibid.
Nor do we believe that any noncompliance with the terms of 7 CFR § 1832.3 during the second loan period would justify the District Court’s remedy.7 Although the District Court did find that this provision had been violated during the initial loan period, it is far from clear from the face of its opinion that it found any such violations during the second period. Even assuming such findings, however, we agree with the conclusion of the Court of Appeals for the Ninth Circuit that the notice provisions of 7 CFR § 1832.3 were no longer applicable during the period after the enactment of Pub. L. 93-237, at least with respect to disasters declared prior to the date the new law came into force. See Emergency Disaster Loan Assn., Inc. v. Block, 653 F. 2d 1267, 1270 (1981).
By its terms, § 1832.3(a) requires only notice of the loan program in place at the time of the Presidential disaster declaration. See also §1832.92 (1975) (describing §1832.3 as [941] setting out procedures for reporting natural disaster designations). Accordingly, its plain language casts serious doubt on respondents’ assumption that it was also intended to serve as a means of giving notice of midcourse changes in the terms of the loan program long after the disaster had been declared.
Any ambiguity about the regulation’s reach is dispelled by the history of Pub. L. 93-237 itself. As the Court of Appeals recognized, Congress was acutely aware of confusion in the administration of the Nation’s disaster relief laws when it enacted Pub. L. 93-237. 714 F. 2d, at 1516-1517. S. Conf. Rep. No. 93-363, p. 6 (1973). A central objective of the new Act was to correct this confusion by clarifying the credit terms available during this period and by requiring the Secretary to extend the application deadline to compensate for prior “uncertainties]” in the law. Ibid. Consistent with that objective, the Secretary announced in the Federal Register the new procedures the agency would follow to “implement] applicable provisions of Public Law 93-237.” 39 Fed. Reg. 7569 (1974). These procedures, which included the notice provision later codified at 7 CFR § 1832.82(a), were designed to “supplement] and modif[y]” the procedures that had been in place under the old regime, including 7 CFR § 1832.3(a). While this language is ambiguous, the regulatory history strongly suggests that in adopting notice procedures specifically geared to the new law, the Secretary intended for those procedures to be the principal mechanism for spreading the word about Pub. L. 93-237 in areas in which a disaster had already been declared. Aware of Congress’ belief that prior efforts to implement the old program had failed, this history suggests, the Secretary sought to take a different tack to assure effective implementation of the new one — notification of the media pursuant to § 1832.82.
This interpretation is confirmed by § 1832.92, also adopted as part of the FmHA’s efforts to implement Pub. L. 93-237. 39 Fed. Reg. 7575 (1974). There, the Secretary specifically provided that for any “new” disaster designations, notice [942] should be given pursuant to § 1832.3. There is no mention whatever of § 1832.3 in the balance of the regulations dealing with disasters that had already been declared at the time the regulation was published. A fair inference from this omission is that for disasters, such as the Florida flood, that had already been declared at the time of the enactment of Pub. L. 93-237, the Secretary intended that § 1832.82(a), rather than § 1832.3, provide the appropriate mechanism for notifying affected farmers about the new loan program. Accordingly, any failure to follow the old notice provisions during the second loan period was entirely consistent with the Secretary’s intended approach and provides no permissible basis for ordering the new program reopened.
HH HH I — I
We conclude, therefore, that the lower courts erred m holding that the Secretary’s conduct violated the only notice procedures relevant to the implementation of Pub. L. 93-237. Accordingly, even assuming, arguendo, that reopening the loan program would have been an appropriate remedy had the relevant regulations been violated, awarding that relief was clearly improper in light of the FmHA’s compliance with its own procedures. Nor can the relief be supported on the theory, not addressed by either court below, that inadequate notice of the loan program deprived respondents of property without due process of law. We have never held that applicants for benefits, as distinct from those already receiving them, have a legitimate claim of entitlement protected by the Due Process Clause of the Fifth or Fourteenth Amendment. Walters v. National Assn. of Radiation Survivors, 473 U. S. 305, 320, n. 8 (1985). Even on the assumption that they do, however, the notice published in the Federal Register, as well as that afforded by the Secretary in full compliance with his own procedures, was more than ample to satisfy any due process concerns. See 44 U. S. C. §1507 (Publication in [943] Federal Register “is sufficient to give notice of the contents of the document to a person subject to or affected by it”).
Accordingly, the judgment of the Court of Appeals is reversed.
It is so ordered.
