Opinion for the Court filed by Chief Judge WALD.
This controversy concerns the adequacy of various types of asbestos-protection respirators. The National Institute for Occupational Safety and Health (NIOSH) and the Environmental Protection Agency (EPA) published in April, 1986, a report recommending that “supplied-air” respirators be used for maximum protection against asbestos exposure. 1 Both agencies are authorized by statute to disseminate health information to the public. See Occupational Safety and Health Act, 29 U.S.C. §§ 669(a), (d), 671; Public Health Servicе Act, 42 U.S.C. §§ 241(a), 4321. 2 Occupational Safety and Health Administration (OSHA) and EPA regulations, however, permit industry members to use numerous devices not recommended in the Guide. 3 Plaintiffs-appellants Industrial Safety Equipment Association (ISEA), et al., brought a district court action on June 10, 1986 seeking declaratory and injunctive relief against publication of the Guide. They argued that the Guide violated the Administrative Procedure Act (APA) because it “constitutes or has the effect of new agency regulations,” decertifying eleven lawful respirator typеs, yet it was not promulgated according to proper rulemaking processes. Secondly, they argued that the publication works an unconstitutional deprivation of their property interests in their respirator certifications.
On February 27, 1987, the district court dismissed with prejudice plaintiffs’ complaint, ruling that because the Guide was a nonbinding, informational publication, it did not amount to reviewable agency action.
I. BACKGROUND
OSHA and EPA regulations protect employees against the serious health hazard posed by asbestos in the workplace. See 29 C.F.R. § 1910.1001; 40 C.F.R. *1117 § 763.21(d). Both sets of regulations require that asbestos-protection respirators be selected from among those certified by the NIOSH and the Mine Safety and Health Administration (MSHA). See 30 C.F.R. Part 11. Specifically, there are thirteen federally approved respirators, ranging from "air purifying respirators” (filter devices) recommended for use when asbestos concentrations are relatively low, to “powered air purifying respirators,” and finally to "supplied-air respirators” (self-contained breathing apparatuses), recommended as concentrations become progressively higher. 4
In April, 1986, the EPA and the NIOSH published the Guide with the stated purpose of providing “a single source for the best and most current information on worker respiratory protection against asbestos.” J.A. at 146. Both parties to this dispute agree that the Guide is also intended “to provide employers with guidelines for developing effective respiratory protection programs.” J.A. at 64 (quoting Guide at 1); see also Brief of Appellees at 6. The Guide summarizes and builds on existing federal regulations that specify both the PELs and the authorized methods of complying with these limits. The largest section of the Guide describes a model program for asbestos abatement operations. The preface explains that the Guide’s recommendations not only satisfy existing regulations but also incorporate the most current scientific information about how best to minimize worker exposure. Respirator use, of course, is a major method of compliance with the PELs. The Guide carefully distinguishes between the thirteen respirators all of which meet federal standards and the two types that the Guide recommends because they provide the maximum amount of worker protection. The most controversial passage in the Guide reads:
The respirator types numbered 3 through 13 above are not recommended by NIOSH or EPA for use against asbestos. However, various existing regulations allow their use. In fact, the existing respirator certification regulations (30 C.F.R. Part 11) requires NIOSH to certify ... [these eleven]. However, as a matter of public health policy, NIOSH and EPA do not recommend their use in asbestos environments.
J.A. at 156 (excerpt is footnote in Guide, prefaced with exclamation “Important”) (boldface and capitalization omitted).
Appellants claim that this disapproval of eleven lawful devices amounts to agency rulemaking, subject to review under the APA, bеcause the action effectively “decer-tifies” the existing respirators marketed or used by appellants. The EPA counters that because the Guide formally binds no one, it cannot be viewed as rulemaking. Although we do not adopt the EPA’s broad assertion that only legally binding publications can ever be reviewable, neither do we accept ISEA’s characterization of the Guide as a de facto decertification of the respirators. We conclude that the EPA and NIOSH’s publication of the Guide does not amount to agency action subject to judicial review.
II. ANALYSIS
A. The Administrative Procedure Act
The APA authorizes review of “[ajgency action made reviewable by statute and final agency action” for which there is no other adequate remedy in a court. 5 U.S.C. § 704 (emphasis added). The APA also specifies that standing for judicial review requires that a party be “adversely affected or aggrieved by agency action.” Id. § 702 (emphasis added). In turn, the Act defines agency action as “the whole or a part of an agency rule, order, license, sanction, relief, of the equivalent or denial thereof, or failure to act.” _ Id. § 551(13). These categories are imprecise, and courts have made the threshold determination of reviewable agency action on a case-by-case basis.
Almost forty years ago, this court declared that publication by a government
*1118
agency of material adverse to a party is not agency action under the APA, and hence is immune from judicial review.

See Hearst Radio v. FCC,
The problem with Hearst Radio’s absolute immunity rule for agency publications is its failure to accommodate two separate goals of a fair administrative process: protеcting parties from false or unauthorized agency news releases and promoting Congress’ clear mandate that government information, particularly from consumer-oriented agencies, reach the public. Both NIOSH and the EPA are charged with protecting the public welfare through investigations and reports on health conditions. See Occupational Safety and Health Act, 29 U.S.C. §§ 669(a), (d), 671; Public Health Service Act, 42 U.S.C. §§ 241(a), 4321, 4364, 4366. And like the National Highway Traffic Safety Administration's defect notification practices, see 15 U.S.C. § 1412, or the FDA’s warnings аbout poisonous foods, see 21 U.S.C. § 375, the NIOSH and EPA powers would be crippled were these agencies not permitted to use the quick and cheap instrument of publicity. The same agency access to publicity, however, can unjustifiably injure other parties. See Gellhorn, Adverse Publicity By Administrative Agencies, 86 Harv.L.Rev. 1380 (1973) (lengthy discussion of industry effects of agency publicity). 7 Though there is broad consensus that this potential for harm is best controlled by internal agency restraint — i.e., careful attention to the accuracy of, the need for, аnd alternatives to adverse publicity, see, e.g., FTC Publicity Guidebook (agency guidelines on use of publicity) — where it does occur, courts have a duty to decide whether there *1119 is a remedy under the APA for the release of the information.
Appellants and the district court analyzed APA review in terms of whether the Guide was a “rule” reviewable as agency action. Before focussing on the Guide’s status as an agency rule, however, we first canvass the APA’s definition of agency actions to ascertain whether the Guide qualifies under anоther category that would justify judicial review.
Apart from “rule,” “sanction” is the only other plausible category of agency action into which an agency’s infliction of harm through publicity might fit. The term “sanction” is defined in the APA as
the whole or a part of an agency (1) prohibition, requirement, limitation, or other condition affecting the freedom of a person; (2) withholding of relief; (3) imposition of penalty or fine; (4) destruction, taking, seizure, or withholding of property; (5) assessment of damages, reimbursement, restitution, compensatiоn, costs, charges, or fees; (6) requirement, revocation or suspension of a license; or (7) taking other compulsory or restrictive action.
5 U.S.C. § 551(10). Although legislative history was not discussed in
Hearst Radio,
Congress itself did note that in certain circumstances adverse publicity might operate as a sanction. H.Rep. No. 79-1980, 79th Cong., 2d Sess. (1946) (House of Representatives Report on APA) (noting that unauthorized use of publicity as penalty or punishment is “troublesome subject”). Thus, though adverse impact alone would not necessarily make agency рublicity reviewable as a sanction,
see American Telephone & Telegraph Co. v. FCC,
Instead, ISEA rests reviewability entirely on its characterization of the Guide as an agency rule. To adopt a substantive rule, an agency must comply with the APA’s section 553 notice and comment requirements. Because no such rulemaking occurred in the present ease, ISEA argues both that the Guide is invalid and that the district court’s dismissal should be reversed. The EPA and NIOSH, on the other hand, contend that the Guide is not a substantive rulе, that it is unreviewable, and, alternatively, that it did not require notice and comment proceedings. We hold that the facts support the district court’s conclusion that the Guide does not qualify ■as agency action and hence is not reviewable. 8
*1120
The APA defines rule as “the whole or a part of an agency statement of general or particular applicability and future effect designed to implement, interpret, or prescribe law or policy_” 5 U.S.C. § 551(4). Clearly Congress did not intend that the APA definition of a rule be construed so broadly that every agency action would be subject to judicial review. ISEA contends, however, that the “Guide takes the extra step necessary to make a ‘report’ an unlawful rulemaking;
i.e.,
it transcends the mere reporting of factual matters and attempts to change and implement law and policy within the statutory definition of rulemaking.” Brief of Appellants at 27. The facts suggest otherwise, however. The Guide does not change any law or official policy presently in effect. It does not narrow or alter the grounds on which the NIOSH will act to certify any of the thirteen lawful respirator types.
Cf. Nader v. CAB,
The advisory character of the NIOSH/EPA report is most evident when one examines the Guide. Starting with its conclusion that “no level of exposure [to asbestos] is known to be without risk,” J.A. at 147, the Guide elaborates a model respiratory protection program for asbestos abatement operations. It emphasizes throughout that the model is an ideal, not a regimen presently mandated by law. The sections that immediately precede and follow the section marked “Respirator Selection,” J.A. at 153, which appellants now protest, are illustrative. The preceding section concerning “Written Standard Operating Procedure” clearly states that federal regulations do not address the issue of how to operate respirators; nevertheless, the Guide vigorously recommends that the regulated industry itself provide exhaustive instructions to workers. And in the sеction that follows “Respirator Selection,” the Guide is even more explicit in advocating voluntary industry protections above and beyond what is required by law: “In addition to existing regulatory requirements, the initial [medical] examination should allow determination as to whether the worker is capable of wearing and using a respirator.” J.A. at 155. Similar examples of hortatory advice appear on every page.
Most important, in the section marked “Respiratory Selection,” the EPA underscores the distinction between the present legal requirements and the current information that informs the Guide’s recommen *1121 dations. 10 In the subsection entitled “Respirators Allowable Under Existing Regulations for Protection Against Asbestos,” where the EPA criticizes existing regulations for not providing maximum protection, there are repeated assurances that the less protective devices still satisfy OSHA and EPA regulations. J.A. at 156, 155 (pages reversed in Joint Appendix) (assurances made in three separate paragraphs).
Our conclusion that the Guide does nоt constitute an agency rule is reinforced by the fact that the Guide — a NIOSH/EPA “technical report” — was published neither in the Federal Register nor in the Code of Federal Regulations, which contains only documents “ ‘having general applicability and legal effect.’ ”
See Brock v. Cathedral Bluffs Shale Oil Co.,
ISEA nonetheless relies on the alleged “substantial impact” of the Guide’s criticisms on mаnufacturers of the disfavored respirators. We note first that this court has rejected the notion that the mere fact that an agency action has “substantial impact” “transform[s] it into a legislative rule.”
See American Postal Workers Union v. United States Postal Service,
B. Due Process
ISEA’s constitutional claim is that the Guide’s warning against the use of certain respirators will deprive appellants of property interests — notably the market value of the certifications of their respirators. Although parties mounting a constitutional challenge to government action
*1122
that stigmatizes them may not encounter the definitional rigidities of the APA,
see, e.g., SCA Services of Indiana, Inc. v. Thomas,
To determine whether there has been an unlawful deprivation of a constitutionally protected prоperty interest we make a three-part inquiry. First, is there a property interest? Second, did the government’s action “deprive” appellants of this interest? And third, if so, were the persons deprived accorded due process protections?
There is no question that appellants possess cognizable property interests in their respirator certifications.
See Bell v. Burson,
Even were we to view the publication as a deprivation, the EPA and NIOSH are discharging their statutory duty to alert the public to potentially hazardous work conditions. Applying the three-part test of
Mathews v. Eldridge,
CONCLUSION
The Guide was designed to advise and recommend to industry employers how to provide maximum asbestos protection to workers. It had no binding legal effect on either buyers or purchasers of certified respirators. Nor was it contemplated that the recommendations would be implemented in the context of future agency proceedings. Finally, appellants did not charge that the recommеndations were false. Under these circumstances, the Guide did not amount to a rule reviewable as agency action or requiring APA rulemaking proceedings; nor did its issuance constitute a deprivation of property interests under the fifth amendment. The district court was correct in dismissing the complaint.
Notes
. The report is entitled A Guide to Respiratory Protection for the Asbestos Abatement Industry. Joint Appendix (J.A.) at 137. Hereafter, the report will be referred to as the “Guide” and appellees will be referred to collectively as either the NIOSH or the EPA.
. The EPA's specific role — financing the inter-agency publication — finds statutory basis in the National Environmental Policy Act, 42 U.S.C. § 4362.
.The NIOSH recently has proposed revisions to the Part 11 program, which specifies asbestos respirator-protection standards. 52 Fed.Reg. 32,402 (proposing changes in tests used to certify respirators). Similarly, on July 21, 1986, new OSHA regulations for asbestos protection took effect. See infra note 4.
. Existing regulations key each respirator type to asbestos concentrations levels, or “permissible exposure limits” (PELs). Recent OSHA revisions to its regulations have reduced these PELs.
. We do not consider the related issue of agency (notably Food and Drug Administration (FDA) or the Securities Exchange Commission (SEC)) press releases that announce the commencement of adjudicatory proceedings.

.Cranberry growers and consumers alike will recall "Black Monday," November 9, 1959. On that day, the Secretary of Health, Education, and Welfare announced that cranberries from the Northwest had been found contaminated with a weed killer. Though later the government declared that 99% of the nation’s crop was untainted, the Secretary said that his family would do without the berries at their Thanksgiving meal. Most Americans chose to make the same sacrifice, and by Christmas, the industry had a $20 million surplus of cranberries. Eventually, taxpayers assumed much of the loss through Farmers Home Loan Administration indemnity payments to cranberry growers. See generally, Gellhorn, supra at 1408-10 & nn. 116, 118. One lesson is clear: Adverse publicity can cause damage even though legal rights remain unaltered and even though the statements are not libelous or tortious.
. Even were we to find that the Guide represents an agency statement of policy, subject to section 551 review, ripeness doctrines would militate against our reaching the merits.
See Office of Communication of United Church of Christ
v.
FCC,
Of course, notice and comment procedures are unnecessary in the case of policy statements. 5 U.S.C. § 553(b)(A);
see also Pacific Gas & Electric Co. v. FPC,
. Despite its exhortation to choose the most protective devices, the EPA, in the text of the Guide as well as in forms in the appendix, details how employers may select any of the thirteen lawful types. See J.A. at 153, 217-19.
. The Guide documents the research that underlies its ranking of respirators according to the extent of protection provided. See J.A. at 156 n. Presumably, in any rulemaking, the regulated industry would challenge these studies. ISEA did not, however, offer evidence in this proceeding to support its claim that the rankings are "unfounded,” see Reply Brief of Appellants at 7, except to argue that in some circumstances the cumbersome outfits would be restrictive. The Guide acknowledges this limitation. See J.A. at 148. Because ISEA doеs not attack the Guide as false or misleading, we need not decide the question left open by this court in Impro Products, Inc. v. Block, 722 F.2d 845, 849 (D.C.Cir.1983), whether the intentional dissemination of false information constitutes agency action subject to review. See supra text accompanying notes 6 & 7.
. Again, even if we found that the Guide’s publication were a reviewable action, it would not follow that notice and comment were required.
Cf. 2
K. Davis, Administrative Law Treatise § 7:20 (1979) (caution that miscellaneous informal agency action, such as "supervising, advising, applying pressure, publicizing [even though these activities may have "substantial impact”] ... rather clearly has to be generally free from any requirement of notice and comment proceedings”). Day-to-day informality and flexibility is indispensable to the agency function; moreover, agencies should not be deterred from producing information that will benefit the public.
