[875]*875Justice Scalia
delivered the opinion of the Court.
In this case we must decide whether respondent, the National Wildlife Federation (hereinafter respondent), is a proper party to challenge actions of the Federal Government relating to certain public lands.
H — (
Respondent filed this action in 1985 in the United States District Court for the District of Columbia against petitioners the United States Department of the Interior, the Secretary of the Interior, and the Director of the Bureau of Land Management (BLM), an agency within the Department. In its amended complaint, respondent alleged that petitioners had violated the Federal Land Policy and Management Act of 1976 (FLPMA), 90 Stat. 2744, 43 U. S. C. § 1701 et seq. (1982 ed.), the National Environmental Policy Act of 1969 (NEPA), 83 Stat. 852, 42 U. S. C. §4321 et seq., and § 10(e) of the Administrative Procedure Act (APA), 5 U. S. C. §706, in the course of administering what the complaint called the “land withdrawal review program” of the BLM. Some background information concerning that program is necessary to an understanding of this dispute.
In various enactments, Congress empowered United States citizens to acquire title to, and rights in, vast portions of federally owned land. See, e. g., Rev. Stat. §2319, 30 U. S. C. §22 et seq. (Mining Law of 1872); 41 Stat. 437, as amended, 30 U. S. C. § 181 et seq. (Mineral Leasing Act of 1920). Congress also provided means, however, for the Executive to remove public lands from the operation of these statutes. The Pickett Act, 36 Stat. 847, 43 U. S. C. § 141 (1970 ed.), repealed, 90 Stat. 2792 (1976), authorized the President “at any time in his discretion, temporarily [to] withdraw from settlement, location, sale, or entry any of the [876]*876public lands of the United States . . . and reserve the same for water-power sites, irrigation, classification of lands, or other public purposes . . . Acting under this and under the Taylor Grazing Act of 1934, ch. 865, 48 Stat. 1269, as amended, 43 U. S. C. §315f, which gave the Secretary of the Interior authority to “classify” public lands as suitable for either disposal or federal retention and management, President Franklin Roosevelt withdrew all unreserved public land from disposal until such time as they were classified. Exec. Order No. 6910, Nov. 26, 1934; Exec. Order No. 6964, Feb. 5, 1935. In 1936, Congress amended § 7 of the Taylor Grazing Act to authorize the Secretary of the Interior “to examine and classify any lands” withdrawn by these orders and by other authority as “more valuable or suitable” for other uses “and to open such lands to entry, selection, or location for disposal in accordance with such classification under applicable public-land laws.” 49 Stat. 1976, 43 U. S. C. §315f (1982 ed.). The amendment also directed that “[s]uch lands shall not be subject to disposition, settlement, or occupation until after the same have been classified and opened to entry.” Ibid. The 1964 classification and multiple use Act, 78 Stat. 986, 43 U. S. C. §§1411-1418 (1970 ed.) (expired 1970), gave the Secretary further authority to classify lands for the purpose of either disposal or retention by the Federal Government.
Management of the public lands under these various laws became chaotic. The Public Land Law Review Commission,. established by Congress in 1964 to study the matter, 78 Stat. 982, determined in 1970 that “virtually all” of the country’s public domain, see Public Land Law Review Commission, One Third of the Nation’s Land 52 (1970) — about one-third of the land within the United States, see id., at 19 — had been withdrawn or classified for retention; that it was difficult to determine “the extent of existing Executive withdrawals and the degree to which withdrawals overlap each other,” id., at 52; and that there were inadequate records to show the pur[877]*877poses of withdrawals and the permissible public uses. Ibid. Accordingly, it recommended that “Congress should provide for a careful review of (1) all Executive withdrawals and reservations, and (2) BLM retention and disposal classifications under the Classification and Multiple Use Act of 1964.” Ibid.
In 1976, Congress passed the FLPMA, which repealed many of the miscellaneous laws governing disposal of public land, 43 U. S. C. § 1701 et seq. (1982 ed.), and established a policy in favor of retaining public lands for multiple use management. It directed the Secretary to “prepare and maintain on a continuing basis an inventory of all public lands and their resource and other values,” § 1711(a), required land use planning for public lands, and established criteria to be used for that purpose, § 1712. It provided that existing classifications of public lands were subject to review in the land use planning process, and that the Secretary could “modify or terminate any such classification consistent with such land use plans.” § 1712(d). It also authorized the Secretary to “make, modify, extend or revoke” withdrawals. § 1714(a). Finally it directed the Secretary, within 15 years, to review withdrawals in existence in 1976 in 11 Western States, § 1714 (0( 1), and to “determine whether, and for how long, the continuation of the existing withdrawal of the lands would be, in his judgment, consistent with the statutory objectives of the programs for which the lands were dedicated and of the other relevant programs,” § 1714(0(2). The activities undertaken by the BLM to comply with these various provisions constitute what respondent’s amended complaint styles the BLM’s “land withdrawal review program,” which is the subject of the current litigation.
Pursuant to the directives of the FLPMA, petitioners engage in a number of different types of administrative action with respect to the various tracts of public land within the United States. First, the BLM conducts the review and recommends the determinations required by § 1714(0 with [878]*878respect to withdrawals in 11 Western States. The law requires the Secretary to “report his recommendations to the President, together with statements of concurrence or non-concurrence submitted by the heads of the departments or agencies which administer the lands”; the President must in turn submit this report to the Congress, together with his recommendation “for action by the Secretary, or for legislation.” § 1714(0(2). The Secretary has submitted a number of reports to the President in accordance with this provision.
Second, the Secretary revokes some withdrawals under § 204(a) of the Act, which the Office of the Solicitor has interpreted to give the Secretary the power to process proposals for revocation of withdrawals made during the “ordinary course of business.” U. S. Dept, of the Interior, Memorandum from the Office of the Solicitor, Oct. 30, 1980. These revocations are initiated in one of three manners: An agency or department holding a portion of withdrawn land that it no longer needs may file a notice of intention to relinquish the lands with the BLM. Any member of the public may file a petition requesting revocation. And in the case of lands held by the BLM, the BLM itself may initiate the revocation proposal. App. 56-57. Withdrawal revocations may be made for several reasons. Some are effected in order to permit sale of the land; some for record-clearing purposes, where the withdrawal designation has been superseded by congressional action or overlaps with another withdrawal designation; some in order to restore the land to multiple use management pursuant to § 102(a)(7) of the FLPMA, 43 U. S. C. § 1701(a)(7) (1982 ed.). App. 142-145.
Third, the Secretary engages in the ongoing process of classifying public lands, either for multiple use management, 43 CFR pt. 2420 (1988), for disposal, pt. 2430, or for other uses. Classification decisions may be initiated by petition, pt. 2450, or by the BLM itself, pt. 2460. Regulations pro[879]*879mulgated by the Secretary prescribe the procedures to be followed in the case of each type of classification determination.
HH I — I
In its complaint, respondent averred generally that the reclassification of some withdrawn lands and the return of others to the public domain would open the lands up to mining activities, thereby destroying their natural beauty. Respondent alleged that petitioners, in the course of administering the Nation’s public lands, had violated the FLPMA by failing to “develop, maintain, and, when appropriate, revise land use plans which provide by tracts or areas for the use of the public lands,” 43 U. S. C. § 1712(a) (1982 ed.); failing to submit recommendations as to withdrawals in the 11 Western States to the President, § 1714(Z); failing to consider multiple uses for the disputed lands, § 1732(a), focusing inordinately on such uses as mineral exploitation and development; and failing to provide public notice of decisions, §§ 1701(a)(5), 1712(c)(9), 1712(f), and 1739(e). Respondent also claimed that petitioners had violated NEPA, which requires federal agencies to “include in every recommendation or report on . . . major Federal actions significantly affecting the quality of the human environment, a detailed statement by the responsible official on . . . the environmental impact of the proposed action.” 42 U. S. C. §4332(2)(C) (1982 ed.). Finally, respondent alleged that all of the above actions were “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law,” and should therefore be set aside pursuant to § 10(e) of the APA, 5 U. S. C. §706. Appended to the amended complaint was a schedule of specific land-status determinations, which the complaint stated had been “taken by defendants since January 1, 1981”; each was identified by a listing in the Federal Register.
In December 1985, the District Court granted respondent’s motion for a preliminary injunction prohibiting petitioners from “[m]odifying, terminating or altering any withdrawal, classification, or other designation governing the protection [880]*880of lands in the public domain that was in effect on January 1, 1981,” and from “[tjaking any action inconsistent” with any such withdrawal, classification, or designation. App. to Pet. for Cert. 185a. In a subsequent order, the court denied petitioners’ motion under Rule 12(b) of the Federal Rules of Civil Procedure to dismiss the complaint for failure to demonstrate standing to challenge petitioners’ actions under the APA, 5 U. S. C. §702. App. to Pet. for Cert. 183a. The Court of Appeals affirmed both orders. National Wildlife Federation v. Burford, 266 U. S. App. D. C. 241, 835 F. 2d 305 (1987). As to the motion to dismiss, the Court of Appeals found sufficient to survive the motion the general allegation in the amended complaint that respondent’s members used environmental resources that would be damaged by petitioners’ actions. See id., at 248, 835 F. 2d, at 312. It held that this allegation, fairly read along with the balance of the complaint, both identified particular land-status actions that respondent sought to challenge — since at least some of the actions complained of were listed in the complaint’s appendix of Federal Register references — and asserted harm to respondent’s members attributable to those particular actions. Id., at 249, 835 F. 2d, at 313. To support the latter point, the Court of Appeals pointed to the affidavits of two of respondent’s members, Peggy Kay Peterson and Richard Erman, which claimed use of land “in the vicinity” of the land covered by two of the listed actions. Thus, the Court of Appeals concluded, there was “concrete indication that [respondent’s] members use specific lands covered by the agency’s Program and will be adversely affected by the agency’s actions,” and the complaint was “sufficiently specific for purposes of a motion to dismiss.” Ibid. On petitions for rehearing, the Court of Appeals stood by its denial of the motion to dismiss and directed the parties and the District Court “to proceed with this litigation with dispatch.” National Wildlife Federation v. Burford, 269 U. S. App. D. C. 271, 272, 844 F. 2d 889, 890 (1988).
[881]*881Back before the District Court, petitioners again claimed, this time by means of a motion for summary judgment under Rule 56 of the Federal Rules of Civil Procedure (which motion had been outstanding during the proceedings before the Court of Appeals), that respondent had no standing to seek judicial review of petitioners’ actions under the APA. After argument on this motion, and in purported response to the court’s postargument request for additional briefing, respondent submitted four additional member affidavits pertaining to the issue of standing. The District Court rejected them as untimely, vacated the injunction, and granted the Rule 56 motion to dismiss. It noted that neither its earlier decision nor the Court of Appeals’ affirmance controlled the question, since both pertained to a motion under Rule 12(b). It found the Peterson and Erman affidavits insufficient to withstand the Rule 56 motion, even as to judicial review of the particular classification decisions to which they pertained. And even if they had been adequate for that limited purpose, the court said, they could not support respondent’s attempted APA challenge to “each of the 1250 or so individual classification terminations and withdrawal revocations” effected under the land withdrawal review program. National Wildlife Federation v. Burford, 699 F. Supp. 327, 332 (DC 1988).
This time the Court of Appeals reversed. National Wildlife Federation v. Burford, 278 U. S. App. D. C. 320, 878 F. 2d 422 (1989). It both found the Peterson and Erman affidavits sufficient in themselves and held that it was an abuse of discretion not to consider the four additional affidavits as well.1 The Court of Appeals also concluded that [882]*882standing to challenge individual classification and withdrawal decisions conferred standing to challenge all such decisions under the land withdrawal review program. We granted certiorari. 493 U. S. 1042 (1990).

A
We first address respondent’s claim that the Peterson and Erman affidavits alone suffice to establish respondent’s right to judicial review of petitioners’ actions. Respondent does not contend that either the FLPMA or NEPA provides a private right of action for violations of its provisions. Rather, respondent claims a right to judicial review under § 10(a) of the APA, which provides:
“A person suffering legal wrong because of agency action, or adversely affected or aggrieved by agency action within the meaning of a relevant statute, is entitled to judicial review thereof.” 5 U. S. C. §702.
This provision contains two separate requirements. First, the person claiming a right to sue must identify some “agency action” that affects him in the specified fashion; it is judicial review “thereof” to which he is entitled. The meaning of “agency action” for purposes of § 702 is set forth in 5 U. S. C. §551(13), see 5 U. S. C. § 701(b)(2) (“For the purpose of this chapter . . . ‘agency action’ ha[s] the meanin[g] given ... by section 551 of this title”), which defines the term as “the whole or a part of an agency rule, order, license, sanction, relief, or the equivalent or denial thereof, or failure to act,” 5 U. S. C. § 551(13). When, as here, review is sought not pursuant to specific authorization in the substantive statute, but only under the general review provisions of the APA, the “agency action” in question must be “final agency action.” See 5 U. S. C. §704 (“Agency action made reviewable by statute and final agency action for which there is no other adequate remedy in a court are subject to judicial review” (emphasis added).
[?]*?Second, the party seeking review under § 702 must show that he has “suffered] legal wrong” because of the challenged agency action, or is “adversely affected or aggrieved” by that action “within the meaning of a relevant statute.” Respondent does not assert that it has suffered “legal wrong,” so we need only discuss the meaning of “adversely affected or aggrieved . . . within the meaning of a relevant statute.” As an original matter, it might be thought that one cannot be “adversely affected or aggrieved within the meaning” of a statute unless the statute in question uses those terms (or terms like them) — as some pre-APA statutes in fact did when conferring rights of judicial review. See, e. g., Federal Communications Act of 1934, § 402(b)(2), 48 Stat. 1093, as amended, 47 U. S. C. §402(b)(6) (1982 ed.). We have long since rejected that interpretation, however, which would have made the judicial review provision of the APA no more than a restatement of pre-existing law. Rather, we have said that to be “adversely affected or aggrieved . . . within the meaning” of a statute, the plaintiff must establish that the injury he complains of (his aggrievement, or the adverse effect upon him) falls within the “zone of interests” sought to be protected by the statutory provision whose violation forms the legal basis for his complaint. See Clarke v. Securities Industry Assn., 479 U. S. 388, 396-397 (1987). Thus, for example, the failure of an agency to comply with a statutory provision requiring “on the record” hearings would assuredly have an adverse effect upon the company that has the contract to record and transcribe the agency’s proceedings; but since the provision was obviously enacted to protect the interests of the parties to the proceedings and not those of the reporters, that company would not be “adversely affected within the meaning” of the statute.
B
Because this case comes to us on petitioners’ motion for summary judgment, we must assess the record under the [884]*884standard set forth in Rule 56 of the Federal Rules of Civil Procedure. Rule- 56(c) states that a party is entitled to summary judgment in his favor “if the pleadings/depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Rule 56(e) further provides:
“When a motion for summary judgment is made and supported as provided in this rule, an adverse party may not rest upon the mere allegations or denials of the adverse party’s pleading, but the adverse party’s response, by affidavits or as otherwise provided in this rule, must set forth specific facts showing that there is a genuine issue for trial. If the adverse party does not so respond, summary judgment, if appropriate, shall be entered against the adverse party.”
As we stated in Celotex Corp. v. Catrett, 477 U. S. 317 (1986), “the plain language of Rule 56(c) mandates the entry of summary judgment, after adequate time for discovery and upon motion, against a party who fails to make a showing sufficient to establish the existence of an element essential to that party’s case, and on which that party will bear the burden of proof at trial.” Id., at 322. Where no such showing is made, “[t]he moving party is ‘entitled to a judgment as a matter of law’ because the nonmoving party has failed to make a sufficient showing on an essential element of her case with respect to which she has the burden of proof.” Id., at 323.
These standards are fully applicable when a defendant moves for summary judgment, in a suit brought under § 702, on the ground that the plaintiff has failed to show that he is “adversely affected or aggrieved by agency action within the meaning of a relevant statute.” The burden is on the party seeking review under § 702 to set forth specific facts (even though they may be controverted by the Government) showing that he has satisfied its terms. Sierra Club v. Morton, [885]*885405 U. S. 727, 740 (1972). Celotex made clear that Rule 56 does not require the moving party to negate the elements of the nonmoving party’s case; to the contrary, “regardless of whether the moving party accompanies its summary judgment motion with affidavits, the motion may, and should, be granted so long as whatever is before the district court demonstrates that the standard for the entry of summary judgment, as set forth in Rule 56(c), is satisfied.” 477 U. S., at 323.
C
We turn, then, to whether the specific facts alleged in the two affidavits considered by the District Court raised a genuine issue of fact as to whether an “agency action” taken by petitioners caused respondent to be “adversely affected or aggrieved . . . within the meaning of a relevant statute.” We assume, since it has been uncontested, that the allegedly affected interests set forth in the affidavits — “recreational use and aesthetic enjoyment” — are sufficiently related to the purposes of respondent association that respondent meets the requirements of § 702 if any of its members do. Hunt v. Washington State Apple Advertising Comm’n, 432 U. S. 333 (1977).
As for the “agency action” requirement, we think that each of the affidavits can be read, as the Court of Appeals believed, to complain of a particular “agency action” as that term is defined in § 551. The parties agree that the Peterson affidavit, judging from the geographic area it describes, must refer to that one of the BLM orders listed in the appendix to the complaint that appears at 49 Fed. Reg. 19904-19905 (1984), an order captioned W-6228 and dated April 30, 1984, terminating the withdrawal classification of some 4,500 acres of land in that area. See, e. g., Brief for Petitioners 8-10. The parties also appear to agree, on the basis of similar deduction, that the Erman affidavit refers to the BLM order listed in the appendix that appears at 47 Fed. Reg. 7232-7233 [886]*886(1982), an order captioned Public Land Order 6156 and dated February 18, 1982.
We also think that whatever “adverse effect” or “aggrievement” is established by the affidavits was “within the meaning of the relevant statute” — ?:, e., met the “zone of interests” test. The relevant statute, of course, is the statute whose violation is the gravamen of the complaint — both the FLPMA and NEPA. We have no doubt that “recreational use and aesthetic enjoyment” are among the sorts of interests those statutes were specifically designed to protect. The only issue, then, is whether the facts alleged in the affidavits showed that those interests of Peterson and Erman were actually affected.
The Peterson affidavit averred:
“My recreational use and aesthetic enjoyment of federal lands, particularly those in the vicinity of South Pass-Green Mountain, Wyoming have been and continue to be adversely affected in fact by the unlawful actions of the Bureau and the Department. In particular, the South Pass-Green Mountain area of Wyoming has been opened to the staking of mining claims and oil and gas leasing, an action which threatens the aesthetic beauty and wildlife habitat potential of these lands.” App. to Pet. for Cert. 191a.
Erman’s affidavit was substantially the same as Peterson’s, with respect to all except the area involved; he claimed use of land “in the vicinity of Grand Canyon National Park, the Arizona Strip (Kanab Plateau), and the Kaibab National Forest.” Id., at 187a.
The District Court found the Peterson affidavit inadequate for the following reasons:
“Peterson . . . claims that she uses federal lands in the vicinity of the South Pass-Green Mountain area of Wyoming for recreational purposes and for aesthetic enjoyment and that her recreational and aesthetic enjoyment [887]*887has been and continues to be adversely affected as the result of the decision of BLM to open it to the staking of mining claims and oil and gas leasing. . . . This decision [W-6228] opened up to mining approximately 4500 acres within a two million acre area, the balance of which, with the exception of 2000 acres, has always been open to mineral leasing and mining. . . . There is no showing that Peterson’s recreational use and enjoyment extends to the particular 4500 acres covered by the decision to terminate classification to the remainder of the two million acres affected by the termination. All she claims is that she uses lands ‘in the vicinity.’ The affidavit on its face contains only a bare allegation of injury, and fails to show specific facts supporting the affiant’s allegation.” 699 F. Supp., at 331 (emphasis in original).
The District Court found the Erman affidavit “similarly flawed.”
“The magnitude of Erman’s claimed injury stretches the imagination. . . . [T]he Arizona Strip consists of all lands in Arizona north and west of the Colorado River on approximately 5.5 million acres, an area one-eighth the size oif the State of Arizona. Furthermore, virtually the entire Strip is and for many years has been open to uranium and other metalliferous mining. The revocation of withdrawal [in Public Land Order 6156] concerned only non-metalliferous mining in the western one-third of the Arizona Strip, an area possessing no potential for non-metalliferous mining.” Id,., at 332.
The Court of Appeals disagreed with the District Court’s assessment as to the Peterson affidavit (and thus found it unnecessary to consider the Erman affidavit) for the following reason:
“If Peterson was not referring to lands in this 4500-acre affected area, her allegation of impairment to her use and enjoyment would be meaningless, or perjurious. . . . [888]*888[T]he trial court overlooks the fact that unless Peterson’s language is read to refer to the lands affected by the Program, the affidavit is, at best, a meaningless document.
“At a minimum, Peterson’s affidavit is ambiguous regarding whether the adversely affected lands are the ones she uses. When presented with ambiguity on a motion for summary judgment, a District Court must resolve any factual issues of controversy in favor of the non-moving party .... This means that the District Court was obliged to resolve any factual ambiguity in favor of NWF, and would have had to assume, for the purposes of summary judgment, that Peterson used the 4500 affected acres.” 278 U. S. App. D. C., at 329, 878 F. 2d, at 431.
That is not the law. In ruling upon a Rule 56 motion, “a District Court must resolve any factual issues of controversy in favor of the non-moving party” only in the sense that, where the facts specifically averred by that party contradict facts specifically averred by the movant, the motion must be denied. That is a world apart from “assuming” that general averments embrace the “specific facts” needed to sustain the complaint. As set forth above, Rule 56(e) provides that judgment “shall be entered” against the nonmoving party unless affidavits or other evidence “set forth specific facts showing that there is a genuine issue for trial.” The object of this provision is not to replace conclusory allegations of the complaint or answer with conclusory allegations of an affidavit. Cf. Anderson v. Liberty Lobby, Inc., 477 U. S. 242, 249 (1986) (“[T]he plaintiff could not rest on his allegations of a conspiracy to get to a jury without ‘any significant probative evidence tending to support the complaint’”), quoting First National Bank of Ariz. v. Cities Service Co., 391 U. S. 253, 290 (1968). Rather, the purpose of Rule 56 is to enable a party who believes there is no genuine dispute as to a specific fact essential to the other side’s case to demand at least one [889]*889sworn averment of that fact before the lengthy process of litigation continues.
At the margins there is some room for debate as to how “specific” must be the “specific facts” that Rule 56(e) requires in a particular case. But where the fact in question is the one put in issue by the §702 challenge here — whether one of respondent’s members has been, or is threatened to be, “adversely affected or aggrieved” by Government action — Rule 56(e) is assuredly not satisfied by averments which state only that one of respondent’s members uses unspecified portions of an immense tract of territory, on some portions of which mining activity has occurred or probably will occur by virtue of the governmental action. It will not do to “presume” the missing facts because without them the affidavits would not establish the injury that they generally allege. That converts the operation of Rule 56 to a circular promenade: plaintiff’s complaint makes general allegation of injury; defendant contests through Rule 56 existence of specific facts to support injury; plaintiff responds with affidavit containing general allegation of injury, which must be deemed to constitute averment of requisite specific facts since otherwise allegation of injury would be unsupported (which is precisely what defendant claims it is).
Respondent places great reliance, as did the Court of Appeals, upon our decision in United States v. Students Challenging Regulatory Agency Procedures (SCRAP), 412 U. S. 669 (1973). The SCRAP opinion, whose expansive expression of what would suffice for § 702 review under its particular facts has never since been emulated by this Court, is of no relevance here, since it involved not a Rule 56 motion for summary judgment but a Rule 12(b) motion to dismiss on the pleadings. The latter, unlike the former, presumes that general allegations embrace those specific facts that are necessary to support the claim. Conley v. Gibson, 355 U. S. 41, 45-46 (1957).
[890]*890IV
We turn next to the Court of Appeals’ alternative holding that the four additional member affidavits proffered by respondent in response to the District Court’s briefing order established its right to § 702 review of agency action.
A
It is impossible that the affidavits would suffice, as the Court of Appeals held, to enable respondent to challenge the entirety of petitioners’ so-called “land withdrawal review program.” That is not an “agency action” within the meaning of §702, much less a “final agency action” within the meaning of §704. The term “land withdrawal review program” (which as far as we know is not derived from any authoritative text) does not refer to a single BLM order or regulation, or even to a completed universe of particular BLM orders and regulations. It is simply the name by which petitioners have occasionally referred to the continuing (and thus constantly changing) operations of the BLM in reviewing withdrawal revocation applications and the classifications of public lands and developing land use plans as required by the FLPMA. It is no more an identifiable “agency action” — much less a “final agency action” — than a “weapons procurement program” of the Department of Defense or a “drug interdiction program” of the Drug Enforcement Administration. As the District Court explained, the “land withdrawal review program” extends to, currently at least, “1250 or so individual classification terminations and withdrawal revocations.” 699 F. Supp., at 332.2
[891]*891Respondent alleges that violation of the law is rampant within this program — failure to revise land use plans in proper fashion, failure to submit certain recommendations to Congress, failure to consider multiple use, inordinate focus upon mineral exploitation, failure to provide required public notice, failure to provide adequate environmental impact statements. Perhaps so. But respondent cannot seek wholesale improvement of this program by court decree, rather than in the offices of the Department or the halls of Congress, where programmatic improvements are normally made. Under the terms of the APA, respondent must direct its attack against some particular “agency action” that causes it harm. Some statutes permit broad regulations to serve as the “agency action,” and thus to be the object of judicial review directly, even before the concrete effects normally required for APA review are felt. Absent such a provision, however, a regulation is not ordinarily considered the type of agency action “ripe” for judicial review under the APA until the scope of the controversy has been reduced to more manageable proportions, and its factual components fleshed out, by some concrete action applying the regulation to the claimant’s situation in a fashion that harms or threatens to harm him. (The major exception, of course, is a substantive rule which as a practical matter requires the plaintiff to adjust his conduct immediately. Such agency action is “ripe” for review at once, whether or not explicit statutory review apart from the APA is provided. See Abbott Laboratories v. Gardner, 387 U. S. 136, 152-154 (1967); Gardner v. Toilet Goods Assn., Inc., 387 U. S. 167, 171-173 (1967). Cf. Toi[892]*892let Goods Assn., Inc. v. Gardner, 387 U. S. 158, 164-166 (1967).)
In the present case, the individual actions of the BLM identified in the six affidavits can be regarded as rules of general applicability (a “rule” is defined in the APA as agency action of “general or particular applicability and future effect,” 5 U. S. C. §551(4) (emphasis added)) announcing, with respect to vast expanses of territory that they cover, the agency’s intent to grant requisite permission for certain activities, to decline to interfere with other activities, and to take other particular action if requested. It may well be, then, that even those individual actions will not be ripe for challenge until some further agency action or inaction more immediately harming the plaintiff occurs.3 But it is at least entirely [893]*893certain that the flaws in the entire “program” — consisting principally of the many individual actions referenced in the complaint, and presumably actions yet to be taken as well— cannot be laid before the courts for wholesale correction under the APA, simply because one of them that is ripe for review adversely affects one of respondent’s members.4
[894]*894The case-by-case approach that this requires is understandably frustrating to an organization such as respondent, which has as its objective across-the-board protection of our Nation’s wildlife and the streams and forests that support it. But this is the traditional, and remains the normal, mode of operation of the courts. Except where Congress explicitly provides for our correction of the administrative process at a higher level of generality, we intervene in the administration of the laws only when, and to the extent that, a specific “final agency action” has an actual or immediately threatened effect. Toilet Goods Assn., 387 U. S., at 164-166. Such an intervention may ultimately have the effect of requiring a regulation, a series of regulations, or even a whole “program” to be revised by the agency in order to avoid the unlawful result that the court discerns. But it is assuredly not as swift or as immediately far-reaching a corrective process as those interested in systemic improvement would desire. Until confided to us, however, more sweeping actions are for the other branches.

The Court of Appeals’ reliance upon the supplemental affidavits was wrong for a second reason: The District Court did not abuse its discretion in declining to admit them. Petitioners filed their motion for summary judgment in September 1986; respondent filed an opposition but did not submit any new evidentiary materials at that time. On June 27, 1988, after the case had made its way for the first time through the Court of Appeals, the District Court announced that it would hold a hearing on July 22 on “the outstanding motions for summary judgment,” which included petitioners’ motion challenging respondent’s § 702 standing. The hearing was held and, as noted earlier, the District Court issued an order directing respondent to file “a supplemental memorandum re[895]*895garding the issue of its standing to proceed.” Record, Doc. No. 274. Although that plainly did not call for the submission of new evidentiary materials, it was in purported response to this order, on August 22, 1988, that respondent submitted (along with the requested legal memorandum) the additional affidavits. The only explanation for the submission (if it can be called an explanation) was contained in a footnote to the memorandum, which simply stated that “NWF now has submitted declarations on behalf of other members of NWF who have been injured by the challenged actions of federal defendants.” Record, Doc. No. 278, p. 18, n. 21. In its November 4, 1988, ruling granting petitioners’ motion, the District Court rejected the additional affidavits as “untimely and in violation of [the court’s briefing] Order.” 699 F. Supp., at 328, n. 3.
Respondent’s evidentiary submission was indeed untimely, both under Rule 56, which requires affidavits in opposition to a summary judgment motion to be served “prior to the day of the hearing,” Fed. Rule Civ. Proc. 56(c), and under Rule 6(d), which states more generally that “[w]hen a motion is supported by affidavit, . . . opposing affidavits may be served not later than 1 day before the hearing, unless the court permits them to be served at some other time.” Rule 6(b) sets out the proper approach in the case of late filings:
“When by these rules or by a notice given thereunder or by order of court an act is required or allowed to be done at or within a specified time, the court for cause shown may at any time in its discretion (1) with or without motion or notice order the period enlarged if request therefor is made before the expiration of the period originally prescribed or as extended by a previous order, or (2) upon motion made after the expiration of the specified period permit the act to be done where the failure to act was the result of excusable neglect . . . .”
This provision not only specifically confers the “discretion” relevant to the present issue, but also provides the mecha[896]*896nism by which that discretion is to be invoked and exercised. First, any extension of a time limitation must be “for cause shown.” Second, although extensions before expiration of the time period may be “with or without motion or notice,” any posideadline extension must be “upon motion made,” and is permissible only where the failure to meet the deadline “was the result of excusable neglect.” Thus, in order to receive the affidavits here, the District Court would have had to regard the very filing of the late document as the “motion made” to file it;5 it would have had to interpret “cause [897]*897shown” to mean merely “cause,” since respondent made no “showing” of cause at all; and finally, it would have had to find as a substantive matter that there was indeed “cause” for the late filing, and that the failure to file on time “was the result of excusable neglect.”
This last substantive obstacle is the greatest of all. The Court of Appeals presumably thought it was overcome because “the papers on which the trial court relied were two years old by the time it requested supplemental memoranda” and because “there was no indication prior to the trial court’s request that [respondent] should have doubted the adequacy of the affidavits it had already submitted.” 278 U. S. App. D. C., at 331, 878 F. 2d, at 433. We do not understand the relevance of the first point; the passage of so long a time as two years suggests, if anything, that respondent had more than the usual amount of time to prepare its response to the motion, and was more than moderately remiss in waiting until after the last moment. As to the suggestion of unfair surprise: A litigant is never justified in assuming that the court has made up its mind until the court expresses itself to that effect, and a litigant’s failure to buttress its position because of confidence in the strength of that position is always indulged in at the litigant’s own risk. In any case, whatever erroneous expectations respondent may have had were surely dispelled by the District Court’s order in June 1988 announcing that the hearing on petitioners’ motion would be held one month later. At least when that order issued, respondent was on notice that its right to sue was at issue, and that (absent proper motion) the time for filing any additional evidentiary materials was, at the latest, the day before the hearing.
[898]*898Perhaps it is true that the District Court could have overcome all the obstacles we have described — apparent lack of a motion, of a showing, and of excusable neglect — to admit the affidavits at issue here. But the proposition that it was compelled to receive them — that it was an abuse of discretion to reject them — cannot be accepted.

Respondent’s final argument is that we should remand this case for the Court of Appeals to decide whether respondent may seek § 702 review of petitioners’ actions in its own right, rather than derivatively through its members. Specifically, it points to allegations in the amended complaint that petitioners unlawfully failed to publish regulations, to invite public participation, and to prepare an environmental impact statement with respect to the “land withdrawal review program” as a whole. In order to show that it is a “person . . . adversely affected or aggrieved” by these failures, it submitted to the District Court a brief affidavit (two pages in the record) by one of its vice presidents, Lynn A. Greenwalt, who stated that respondent’s mission is to “inform its members and the general public about conservation issues” and to advocate improvements in laws and administrative practices “pertaining to the protection and enhancement of federal lands,” App. to Pet. for Cert. 193a-194a; and that its ability to perform this mission has been impaired by petitioners’ failure “to provide adequate information and opportunities for public participation with respect to the Land Withdrawal Review Program.” Id., at 194a. The District Court found this affidavit insufficient to establish respondent’s right to seek judicial review, since it was “conclusory and completely devoid of specific facts.” 699 F. Supp., at 330. The Court of Appeals, having reversed the District Court on the grounds discussed above, did not address the issue.
We agree with the District Court’s disposition. Even assuming that the affidavit set forth “specific facts,” Fed. R. [899]*899Civ. Proe. 56(e), adequate to show injury to respondent through the deprivation of information; and even assuming that providing information to organizations such as respondent was one of the objectives of the statutes allegedly violated, so that respondent is “aggrieved within the meaning” of those statutes; nonetheless, the Greenwalt affidavit fails to identify any particular “agency action” that was the source of these injuries. The only sentences addressed to that point are as follows:
“NWF’s ability to meet these obligations to its members has been significantly impaired by the failure of the Bureau of Land Management and the Department of the Interior to provide adequate information and opportunities for public participation with respect to the Land Withdrawal Review Program. These interests of NWF have been injured by the actions of the Bureau and the Department and would be irreparably harmed by the continued failure to provide meaningful opportunities for public input and access to information regarding the Land Withdrawal Review Program.” App. to Pet. for Cert. 194a.
As is evident, this is even more deficient than the Peterson and Erman affidavits, which contained geographical descriptions whereby at least an action as general as a particular classification decision could be identified as the source of the grievance. As we discussed earlier, the “land withdrawal review program” is not an identifiable action or event. With regard to alleged deficiencies in providing information and permitting public participation, as with regard to the other illegalities alleged in the complaint, respondent cannot demand a general judicial review of the BLM’s day-to-day operations. The Greenwalt affidavit, like the others, does not set forth the specific facts necessary to survive a Rule 56 motion.

For the foregoing reasons, the judgment of the Court of Appeals is reversed.
It is so ordered.
