dissenting:
Claiming the most arbitrary and unreviewable authority currently approved under federal law, the Department of Energy (DOE) declared two roadways and a railroad track over which it holds an easement criminally inaccessible to all citizens except an undefined group of consentees. It then had arrested and charged with criminal violations a large number of citizens who had legally and persistently appeared on this land for more than a year to register their concerns about the dangers of nuclear power activities being carried out in the Rocky Flats plant more than a mile and a half away. The DOE’s claim to this broad, unchecked authority was based upon one sentence in the legislative creation of the Atomic Energy Commission (AEC),1 enacted more than 21 years before the DOE was established.2 The DOE’s sweeping assumption of authority has never been the subject of hearings or debate in Congress or of traditional administrative hearings required by § 553 of the Administrative Procedure Act (APA), 5 U.S.C. § 553 and the congressionally mandated rulemaking procedures for the DOE, 42 U.S.C. § 7191.3 The majority of this court now ratifies this suppression of debate under principles that alarmingly would permit the same type of *1287unaccountable action with regard to millions of acres of government-owned land controlled by the DOE, and, in light of the easements involved in this case, untold acres of land that arguably fall within the DOE’s “jurisdiction, administration, or ... custody.”4 42 U.S.C. § 2278a(a). The implications for the nearly one billion acres of government-owned land5 cannot be ignored.
These cases arise out of the growing and often strident debate over the wisdom and safety of using nuclear energy in our society. Quite typically, this dispute does not come here under that name or framed precisely in those terms. Such cases usually arrive at the courts in the form of criminal charges for conducting a parade without a permit, obstructing traffic, disturbing the peace, conducting an illegal boycott, assembling unlawfully, trespassing or engaging in similar criminal or quasi-criminal conduct. As in this case, there is rarely any doubt that the defendants have violated whatever official prohibition prosecutors or other officials have elected to invoke in their effort to prohibit, disturb, or alter the form of debate. The proper role of the courts in these cases is not to examine the merits of the debates, but rather to determine whether the place chosen by the defendants to carry on the debates has been unlawfully or unconstitutionally declared inaccessible under the guise of police regulation. Sometimes our constitutional mandate requires us to determine whether the ordinance, regulation, or legislation on its face exceeds the bounds set by the first amendment, but such a constitutional examination is to be avoided if possible.6 However, when examining threshold questions we constantly *1288must be alert to whether the regulations have the effect of impinging upon or threatening first amendment values. If they do, our inquiry must be all the more rigorous.
While the issues before us cause us to focus on threshold questions antecedent to direct first amendment issues, properly perceived they involve the same values. Indeed, if what I believe to be the mandated procedures of the APA and the specific congressionally mandated rulemaking procedures of the DOE had been followed, there is a substantial prospect that parts of this debate would have been transferred from roadways (traditional, but perhaps not preferred, forums for petition for redress of grievances) to a forum that would have fostered a full exchange of information, and would have produced a record from which we could determine whether the DOE’s actions conformed to minimum administrative, legislative, and constitutional standards.
I.
Although numerous other questions have arisen during these trials, the principal and, in my view, the dispositive issue is whether the DOE properly may determine, without a hearing, that any nonpermissive presence on these roadways and rights-of-way will, from the moment of that determination and actual notice to the defendants, become a criminal act.7 The corollary to that question is whether, as required by APA § 553, these unelected administrators must submit any proposal that turns previously lawful conduct into criminal conduct to debate and recorded justifications that permit effective judicial scrutiny. I believe there is no doubt that APA § 553 and the rulemaking procedures specifically established for the DOE apply to this case. However, in any event, since we deal with a difficult question in the murky field of administrative lawmaking, interpretation, and administration, I believe that any doubt about the APA’s applicability ought to be resolved in favor of requiring the debate and justification procedures of APA § 553. This canon of construction is all the more urgent in the context of this case where the inevitable consequence of the DOE’s hasty actions is to turn otherwise innocent behavior into criminal behavior.8 A further reason to follow this canon of construction in this case is the real, and not fancied, ambient presence of first amendment values.
This extensive prelude is necessary because to date the administrative, prosecutorial, and judicial processes appear to have trivialized the importance of these cases.9 I do not attribute any improper motivation to *1289the courts who, given the magnitude of the arrests and charges, processed these cases with commendable efficiency and care for procedural regularity and fairness. Nor am I unsympathetic to the plight of administrators who are confronted with the amazing persistence and irritating presence of persons who represent a threat to the continued legislative and public support of the mission in which their agency is engaged. While we may wish that unpleasant disputes, as well as the underlying fears and concerns, will just go away, they will not. Our duty on review is to insure that the processes surrounding the debate stay within legislative and constitutional bounds.

The Rocky Flats nuclear generating plant is located near Denver, Colorado. It was constructed by the AEC in 1952 and enclosed by a secure chain link fence. At that time the AEC was not given power to exclude persons on the grounds of trespass. In 1956 Congress amended the Act to authorize the AEC “to issue regulations relating to the entry upon . . . any facility, installation, or real property” under its jurisdiction. 42 U.S.C. § 2278a(a). The AEC first promulgated a regulation pursuant to this authority in 1963, which prohibited “[unauthorized entry upon any facility, installation or real property subject to this part.” 10 C.F.R. § 860.3 (emphasis added).10 No attempt was made in that regulation to designate what lands, if any, would be included. It expressly left to future determination the designation of facilities, installations or real property that should be made subject to the prohibition. In 1965 the AEC designated the Rocky Flats site as subject to trespass restrictions. 30 Fed. Reg. 13,289 (1965). This designation included only that area enclosed in the original chain link fence and security system. In 1975 an AEC successor (ERDA) acquired a substantial body of surrounding property, apparently to prevent encroachment of land developers. All of these steps were taken when the agency had a very limited scope and function. In 1977, the DOE was created and given vastly expanded functions, including the functions formerly belonging to the AEC. This was done without consideration of or reference to the prior grant of security functions to the AEC — these functions were anonymously included in a blanket transfer.11
Sixteen days before the arrest of these defendants, the DOE greatly expanded the *1290designated trespass area to include the 1975 ERDA acquisitions and the railroad easement over private lands adjacent to the plant. 44 Fed.Reg. 22, 145 (1979). The majority held that the establishment of the federal crime of trespass at the site where appellants were arrested occurred in 1965— some ten years before the federal government even acquired the land where the violations occurred. The majority reasons that the adoption of the anti-trespassing regulation in 1963 and the designation of the facility at Rocky Flats in 1965 as a facility subject to this regulation satisfy the notice and comment requirements of the APA. Precisely because the DOE did not follow the hearing requirements of APA § 553 in extending the trespass designation, we do not know whether any purpose other than the stifling of debate was served by this extension of criminal jurisdiction. Since the arrest sites are more than a mile from the security fence, much further away than some private lands not subject to these regulations, and because there is no evidence that the defendants’ protests seriously interfered with plant functions or ingress and egress, the implications of interference with and stifling of free speech are compelling.
If a pressing security need existed for the extension of the boundaries (a proposition certainly not supported by the record), Congress provided emergency procedures for such a contingency. 42 U.S.C. § 7191(e); 5 U.S.C. § 553(b)(B).12 No attempt was made to invoke them here, evidently because this case involves not security of the facility, but security of the policies that were perceived as threatened by controversy and notoriety.
III.
Section 553 of the APA, made applicable to the DOE by 42 U.S.C. § 7191(a), requires
that an agency promulgating a rule provide interested persons with notice of the rule-making and an opportunity for comment. 5 U.S.C. §§ 553(b), (c). The objective of these provisions is not merely to give notice, but also to insure opportunity for debate and mature consideration of the proposal. In addition, the required publication of a rule promulgated in accordance with this procedure must be made at least 30 days before it becomes effective. 5 U.S.C. § 553(d); 42 U.S.C. § 7191(b). The only publication of the enlarged designated trespass area was made 16 days prior to the arrests. Furthermore, the congressionally mandated rulemaking procedures for the DOE, which are stricter than the APA in some respects, specifically require that “[sjuch publication shall be accompanied by a statement of the research, analysis, and other available information in support of, the need for, and the probable effect of, any such proposed rule, regulation, or order.” 42 U.S.C. § 7191(b)(1). It is clear that none of the trespass “designations” of the Rocky Flats plant site conformed to these requirements. Consequently, because these rules are subject to the APA, they are invalid so that, in my opinion, the defendants were not trespassing when arrested. See NLRB v. Wyman-Gordon Co., 394 U.S. 759, 763-66, 89 S.Ct. 1426, 1428-29, 22 L.Ed.2d 709 (1969) (plurality opinion); Joseph v. United States Civil Service Commission, 554 F.2d 1140, 1153-54 (D.C.Cir.1977). The weakness of the majority’s conclusion that the DOE’s actions do not constitute rulemaking is underscored by the fact that the majority relies heavily on a line of reasoning noticeably devoid of citation to authority.
All legislative or substantive rules issued pursuant to a delegation of congressional *1291authority — in this case, 42 U.S.C. § 2278a— and having the force of law are subject to the requirements of APA § 553 unless otherwise exempt. The APA defines a “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). The majority characterizes the agency designations as mere ministerial acts, and not rules. However, the clear meaning of the word “ministerial” and the express language of § 551(4) belie that characterization. A ministerial act, by definition, “is one in respect to which nothing is left to discretion. It is a simple, definite duty, arising, under conditions admitted or proved to exist, and imposed by law.” Mississippi v. Johnson, 71 U.S. (4 Wall.) 475, 498-99, 18 L.Ed. 437 (1867). See Statter v. United States, 66 F.2d 819, 821 (9th Cir. 1933). It cannot seriously be argued that a decision to make thousands of acres of government-owned property inaccessible to the public is a ministerial act involving no exercise of discretion. Clearly, such an act is “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).
If, as the majority concludes, the regulations appearing in 10 C.F.R. § 860 are the only “rules” promulgated under 42 U.S.C. § 2278a for which § 553 notice and comment procedures are required, an agency can successfully circumvent the purpose of § 553. Meaningful comment cannot be expected until the agency specifically applies the terms of the enabling statute. No one could have known where and how the delegated power would be exercised or if such exercise would be reasonable until specific areas were designated. An agency should not be permitted to exempt itself from the congressionally mandated requirements of the APA through its own regulations.
The DOE’s actions in this case are not appropriately characterized as falling within any of the exceptions expressly provided for in the APA. APA § 553 is expressly made inapplicable to “interpretative rules [and] general statements of policy.”13 5 U.S.C. § 553(b)(A). An interpretative rule or policy statement is a declaration issued without lawmaking authority or without any intent to exercise that authority. See generally Joseph v. United States Civil Service Commission, 554 F.2d at 1153-54 nn.24, 26; 2 K. Davis, Administrative Law Treatise, §§ 7:5-7:19 (2d ed. 1979). An interpretative rule is not finally determinative of the issues it addresses; rather it announces the course the agency plans to take in future rulemakings or adjudications. Pacific Gas & Electric Co. v. FPC, 506 F.2d 33, 37 nn.14, 38, 41 (D.C.Cir.1974). An interpretative rule is not one “which the public is required to obey,” Airport Commission v. CAB, 300 F.2d 185, 188 (4th Cir. 1962), “does not impose any rights and obligations,” Texaco, Inc. v. FPC, 412 F.2d 740, 744 (3rd Cir. 1969), and “has no independent binding effect.” Eastern Kentucky Welfare Rights Organization v. Simon, 506 F.2d 1278, 1290 (D.C.Cir.1974), vacated for lack of standing, 426 U.S. 26, 96 S.Ct. 1917, 48 L.Ed.2d 450 (1976). Even a policy which purports merely to suggest how agency discretion should be exercised becomes a legislative rule when it effectively circumscribes *1292any choice and mandates a certain result. See Guardian Federal Savings & Loan Association v. FSLIC, 589 F.2d 658, 666-68 (D.C.Cir.1978). Cf. Noel v. Chapman, 508 F.2d 1023, 1030 (2d Cir.), cert. denied, 423 U.S. 824, 96 S.Ct. 37, 46 L.Ed.2d 40 (1975). In short, a rule which changes law or makes law cannot be merely interpretative. See Detroit Edison Co. v. EPA, 496 F.2d 244, 248-49 (6th Cir. 1974); Shell Oil Co. v. FPC, 491 F.2d 82, 87-88 (5th Cir. 1974); National Association of Insurance Agents, Inc. v. Board of Governors, 489 F.2d 1268, 1270 (D.C.Cir.1974).
Obviously, then, the DOE’s conduct in this case is not interpretative. The conduct is also not a mere statement of policy. Any decision that affects thousands of acres of land and immediately criminalizes otherwise legitimate behavior cannot, under any stretch of the imagination, be labeled a mere “statement of policy.”
The distinctions drawn by these cases dictate that the designations that changed what would have been lawful entry on federal land into criminal trespass are legislative in character. In issuing the designations, the DOE and its predecessors clearly intended to bind the courts and to determine the rights and liabilities of those entering the Rocky Flats area. The designations not only impose obligations on the defendants, they also authorize criminal sanctions for failure to obey. If turning previously lawful presence on public lands into criminal trespass is not substantive rulemaking, then nothing is. If the APA is to have any meaning, it must be strictly applied when criminal consequences are involved. See generally United States v. Gavrilovic, 551 F.2d 1099, 1103, 1106 (8th Cir. 1977).
Although the parallels apparently escape the majority, there is a close comparison between this case and Joseph v. United States Civil Service Commission, 554 F.2d 1140 (D.C.Cir.1977). The Civil Service Commission was empowered under 5 U.S.C. § 7327(b) to create exceptions to the Hatch Act. Pursuant to this authority, the Commission issued a regulation in 1970 designating a list of municipalities wherein a federal employee
may take an active part in political management and political campaigns in connection with partisan elections for local offices . . . subject to the following, limitations:
(1) Participation in politics shall be as an independent candidate or on behalf of, or in opposition to, an independent candidate.
5 C.F.R. § 733.124(c). Four years later, the District of Columbia was added to the exempt municipalities list by a notice of amendment published in the Federal Register. 39 Fed.Reg. 18,761 (1974). The District of Columbia Circuit Court of Appeals held that the addition must be classified as a legislative, rather than interpretative, rule and that it was therefore invalid because it was not issued in conformity with APA § 553:
When it added the District to its exemption regulation the Commission clearly intended to exercise [its delegated] authority and promulgate a rule with the full force of law. Whether or not the District of Columbia is to be exempt from Hatch Act prohibitions is not a matter requiring either clarification of statutory language or a public indication of how the Commission will exercise a discretionary power.
554 F.2d at 1153.
Although the majority attempts unconvincingly to distinguish Joseph factually, the reasoning of that case is directly applicable in this case. The Rocky Flats designations represent attempts to exercise and implement the authority delegated by 42 U.S.C. § 2278a(a). Until the responsible agency designated particular tracts of land as subject to restrictions, 42 U.S.C. § 2278a and 10 C.F.R. § 860 were hollow shells, devoid of substance. Specific designations through proper administrative procedures were essential to make the provisions effec*1293tive and enforceable with respect to each parcel of land included in the no trespassing area. Accordingly, these designations are substantive rules subject to the notice and comment procedures of APA § 553. The 1979 designation expanding the boundaries substantively affected the enforcement scheme in the same manner that the inclusion ' of the District of Columbia affected the Civil Service scheme in Joseph. See also Law Motor Freight, Inc. v. CAB, 364 F.2d 139, 142-43 (1st Cir. 1966), cert. denied, 387 U.S. 905, 87 S.Ct. 1683, 18 L.Ed.2d 622 (1967); Hotch v. United States, 212 F.2d 280 (9th Cir. 1954). Contrary to the majority, I cannot conclude that the mere designation of Rocky Flats at one time effectively encompasses any area the government may later annex to, or designate as, “Rocky Flats” for the purpose of restricting entrance to government lands. Such rules cannot be valid unless promulgated in conformity with APA § 553. The majority states that the property description contained in the 1965 designation was mere “surplusage.” If so, then the majority effectively empowers federal agencies to create whatever rules they wish pertaining to federal facilities, which will apply to any land within whatever the agency chooses to call the boundaries on a particular day. This, of course, prevents the notice, discussion, and consideration process mandated by the APA.14
IV.
The government argues that the defendants’ actual notice of the entry restrictions at Rocky Flats15 bars a defense based on the “technical” requirements of the APA. This argument, however, is inappropriate under the circumstances of this case.
The APA speaks to two points along the administrative continuum at which interested parties must be notified. APA § 553(b) requires that “general notice of proposed rulemaking ... be published in the Federal Register, unless persons subject thereto . . . have actual notice thereof.” (Emphasis added). In response to such a notice, had it been given, the defendants could have participated in what would have been the rule-making proceedings on the DOE’s proposal to limit the physical arena for debate over Rocky Flats. APA § 553(d), on the other hand, deals with publication of final rules which have been promulgated pursuant to agency rulemaking procedures. Section 553(d) requires that a substantive rule be published or served “not less than 30 days before its effective date.” Section 553(d) does not contain an actual notice exception. However, the public information provision of the Freedom of Information Act, 5 U.S.C. § 552(a), which requires that substantive rules be published in the Federal Register, does contain such an exception.
Affected parties, then, are entitled to be notified, either through the Federal Register or actually, at two points before an agency’s notion can become a rule that will be binding. It is crucial to bear in mind that the rulemaking process precedes and is different from a substantive rule. Notice of proposed rulemaking will not make a final rule that was promulgated without proper notice effective, and notice that a final rule has been promulgated will not cure lack of notice of contemplated rule-making. The two notices serve different purposes and are not interchangeable.
Thus, defendants’ actual notice that Rocky Flats’ restricted area had been expanded cannot be construed as satisfying the § 553(b) notice of proposed rulemaking requirements. At the time of this actual notice, the time for comment and discussion *1294of the proposed designation was long past. In fact, there never was such a time since no rulemaking procedures were ever proposed or conducted for these designations. Therefore, affected persons could not have been given notice of them. Cf. Texaco, Inc. v. Federal Energy Administration, 531 F.2d 1071, 1081-82 (TECA), cert. denied, 426 U.S. 941, 96 S.Ct. 2662, 49 L.Ed.2d 394 (1976). Notice of a final rule, by publication or actual notice, does not cure improper notice and comment procedures. See National Tour Brokers Association v. United States, 591 F.2d 896, 901-02 (D.C.Cir.1978); City of New York v. Diamond, 379 F.Supp. 503, 515-18 (S.D.N.Y.1974). “Section 4(b) of the Administrative Procedure Act [5 U.S.C. § 553(b)] requires notice before rulemaking, not after.” Wagner Electric Corp. v. Volpe, 466 F.2d 1013, 1020 (3rd Cir. 1972). “ ‘The required publication ... of a substantive rule’ [§ 553(d) ] does not relate back or refer to the publication of ‘[g]eneral notice of proposed rulemaking’ [§ 553(b) ].” Attorney General’s Manual on the Administrative Procedure Act 36 (1947). See also United States v. Gavrilovic, 551 F.2d 1099, 1104 n.9 (8th Cir. 1977).
Even if the actual notice provision of the Freedom of Information Act, 5 U.S.C. § 552(a), excused publication of a final rule in the Federal Register,16 it does not address the § 553(b) requirement of notice of proposed rulemaking.
In short, the statutes regulating the publication of adopted rules do not nullify the requirement of proper promulgation contained in APA §§ 553(b), (c):
On its face, section 552 requires only the publication of existing rules .... The section requires agencies to make “available ”... the substantive rules and general policies which have been “adopted” or “formulated and adopted.” This interpretation is bolstered by the existence of an entirely separate section, § 553, headed “rulemaking,” and by the legislative history of the APA itself.
City of Santa Clara v. Andrus, 572 F.2d 660, 673 (9th Cir.), cert. denied, 439 U.S. 859, 99 S.Ct. 176, 58 L.Ed.2d 167 (1978) (emphasis added). An agency should not be allowed wholly to escape the rigors of rulemaking prescribed by APA § 553 by informing detrimentally affected persons of the terms of an illegally issued rule moments before a violation.17
V.
Although experience may justify some cynicism about the utility of administrative *1295hearings, the law does not authorize us to surrender to that cynicism as today’s opinion does. The underlying thesis of the APA, however contrary to bureaucratic nature, is that an administrative agency will implement sounder policy after hearings have revealed any objections to proposed agency plans and the agency has carefully weighed the evidence and considered the objections. Even if this process fails to impress a determined agency, the hearing will at least provide a record that will permit informed judicial review. The procedures we ratify today require us to act without satisfactory evidence to determine whether any significant purpose other than the stifling of debate was served or intended to be served by the extension of boundaries marked for trespass.
Naturally, no agency wishes to face the protests of citizens who object to its actions. It is often embarrassing and inconvenient. It may even create a public outcry resulting in a cancellation of agency missions. It is the very purpose of the APA notice and comment procedures to insure that, when Congress surrenders its deliberative duties to one of many bureaucracies, detailed actions not tested by congressional debate will be tested by public debate under administrative auspices. That was not done here and no notice can cure the deficiency. Our irritation with demonstrative (although essentially passive) debate techniques should not lead us to dispense with debate or to ratify confrontive responses by public servants. The actions in this case suggest the danger inherent in bypassing established administrative processes.
Although I agree with most of the discussion of most of the issues in these cases, I would reverse the convictions of every defendant arrested and charged under improperly promulgated DOE rules.
McKAY, Circuit Judge, with whom LOGAN and SEYMOUR Circuit Judges, concur in the dissent.. “The [Atomic Energy] Commission is authorized to issue regulations relating to the entry upon . . any facility, installation, or real property subject to the jurisdiction, administration, or in the custody of the Commission.” 42 U.S.C. § 2278a(a).
. The Atomic Energy Commission (AEC) was established by the Atomic Energy Act of 1946, as amended in 1954. In 1956, Congress added 42 U.S.C. § 2278a to the Atomic Energy Act of 1954. That provision gave the AEC the power to regulate entry upon “any facility, installation, or real property subject to the jurisdiction, administration, or in the custody of the [Atomic Energy] Commission.” Willful violation of any such regulation could result in a fine of up to $1,000. Pursuant to this authorization, the AEC issued implementing regulations in 1963. 10 C.F.R. § 160 (1963) (current version at 10 C.F.R. § 860). In 1974, the AEC was abolished and most of its functions were transferred to the Energy Research and Development Administration (ERDA). 42 U.S.C. § 5814 (1974). In 1977, Congress created the Department of Energy (DOE), 42 U.S.C. § 7131 (1977), and transferred to the DOE various functions of many federal agencies, including the ERDA. Id. at § 7151.
. Because the requirements of APA § 553 were ignored, we are not told why the DOE decided to expand the trespass boundaries so far beyond those which served the plant for many years.
. The DOE has direct control of more than 2,350,000 acres of government-owned property. General Services Administration, Summary report of real property owned by the United States throughout the world as of September 30, 1978, at 39, 44 (August 1979). See 42 U.S.C. §§ 7152(a), 7156. In addition, the DOE has varying degrees of authority over the vast amount of public land subject to the Outer Continental Shelf Lands Act, 43 U.S.C. §§ 1331 et seq.; the Mineral Lands Leasing Act, 30 U.S.C. §§ 181 et seq.) the Mineral Leasing Act for Acquired Lands, 30 U.S.C. §§ 351 et seq.) the Geothermal Steam Act of 1970, 30 U.S.C. §§ 1001 et seq.) and the Energy Policy and Conservation Act, 42 U.S.C. §§ 6201 et seq. See 42 U.S.C. § 7152(b). As of 1977, mineral leases had been awarded on over 86 million acres of public land, and nearly nine million acres of land had been leased under the Outer Continental Shelf Lands Act. See United States Department of Commerce, Bureau of Census, Statistical Abstract of the United States, at 237, 761 (September 1979).
. In 1978, the United States held over 775 million acres of land in trust for its citizens. See General Services Administration, Summary report of real property owned by the United States throughout the world as of September 30, 1978, at 7 (August 1979).
. See NLRB v. Catholic Bishop, 440 U.S. 490, 500, 99 S.Ct. 1313, 1318, 59 L.Ed.2d 533 (1979). My analysis would make it unnecessary to consider whether these roads and rights-of-way up to a mile and a half from the Rocky Flats facility are more like public streets or parks, Hague v. C.I.O., 307 U.S. 496, 515-16, 59 S.Ct. 954, 963-64, 83 L.Ed. 1423 (1939) (“The privilege of a citizen ... to use the streets and parks for communication of views on national questions . .. must not, in the guise of regulation, be abridged or denied”), than they are like army posts, Greer v. Spock, 424 U.S. 828, 838, 96 S.Ct. 1211, 1217, 47 L.Ed.2d 505 (1976) (noting “the historically unquestioned power of [its] commanding officer summarily to exclude civilians from the area of his command”). At the very least, the area at which these protesters were arrested is arguably a public place; indeed, protesters had gathered there on previous occasions without incident. See Albany Welfare Rights Organization v. Wyman, 493 F.2d 1319 (2d Cir. 1974) (holding unconstitutional an absolute ban on leafletting in welfare offices where such leafletting had been permitted previously), cert. denied, 419 U.S. 838, 95 S.Ct. 66, 42 L.Ed.2d 64 (1974). The DOE’s decision absolutely to prohibit all speech in the area by means of an extremely broad trespassing rule would be very difficult to sustain. The Constitution perceives a difference between absolute prohibition and mere regulation of speech. See Stone, Fora Americana: Speech in Public Places, 1974 Sup.Ct.Rev. 233, 239-45. The latter has been affirmed only when “significant governmental interests” are shown to be furthered. Grayned v. City of Rockford, 408 U.S. 104, 115-16, 92 S.Ct. 2294, 2302-03, 33 L.Ed.2d 222 (1972). The former has withstood constitutional scrutiny only in rare circumstances not present here. See Greer v. Spock, 424 U.S. 828, 96 S.Ct. 1211, 47 L.Ed.2d 505 (1975).
*1288Even if this sweeping exclusion of virtually all persons from the protest area can be seen as a mere regulation, it would have to be supported by compelling justifications: “[T]he delicate and difficult task falls upon the courts to weigh the circumstances and to appraise the substantiality of the reasons advanced in support of the regulation of the free enjoyment of” the freedom of speech. Schneider v. State, 308 U.S. 147, 161, 60 S.Ct. 146, 150, 84 L.Ed. 155 (1939). In light of the symbolic propriety of taking one’s protest to its source, see Brown v. Louisiana, 383 U.S. 131, 86 S.Ct. 719, 15 L.Ed.2d 637 (1966), the DOE’s burden should be all the heavier. Yet, due to a failure to comply with APA § 553, we have been provided with absolutely no record of the DOE’s reasons for its action. The balancing required by the Constitution in this case has thus been sabotaged from the outset.
. I do not dissent from the disposition of those issues other than the issue treated here. I do believe, however, that they are preempted by this overriding issue.
. A proper respect for the principles of lenity and caution in finding otherwise protected conduct criminal suggests, at the very least, that where doubt exists, the congressionally mandated hearing procedures of APA § 553 should be followed. Cf. Rewis v. United States, 401 U.S. 808, 812, 91 S.Ct. 1056, 1059, 28 L.Ed.2d 493 (1971). Surely, at least some doubt exists in this case.
. The majority’s attempt to characterize this case as one involving the mere ministerial function of moving signs or fence posts is clearly betrayed by the fact that these “ministerial” acts expanded criminal jurisdiction of the DOE over thousands of additional acres and turned previously lawful conduct into a crime. Of course, if one chooses to characterize these matters as the mere moving of fence posts or *1289as simple questions of whether someone has set foot in a forbidden place, these cases are trivial. Approached in the same frame of mind, great cases in our civil rights revolution were equally trivial. Lest there be a temptation to suggest that the debate before us is somehow unimportant, the issues must be examined against the backdrop of Three Mile Island, the Love Canal, the Jack Rabbit Flats nuclear fallout cases, the asbestos cases and myriad other such cases that are wending their way through the courts as demands for reparation for injuries to innocent and unsuspecting citizens. Our cases become urgently more important because they are attempts through debate or, if preferred, protests, to persuade those who wield governmental power to change policy in advance of perceived destruction. It may well be that the factual claims are doubtful. However, there is no doubt that the issues of the debate are of immense and dramatic significance both from the perspective of those who advocate the use of nuclear facilities as a means of combating our fuel crises and those who claim that such a course is worse that the evil sought to be circumvented.
. There is no evidence that suggests this generalized regulation was not promulgated pursuant to APA § 553.
. See note 2, supra. The majority states as an “aside” that “[tjhe regulation when promulgated was within the express exception from the APA contained in 5 U.S.C. § 553(a)(2) as involving a matter relating to public property.” U. S. v. Thompson,- F.2d -,-(10th Cir. 1982). The majority thus implies that the expanded trespass designation would still be within this exception. However, Congress, by statute, expressly stated that this exception “shall not be available” to the DOE. 42 U.S.C. § 7191(b)(3). There is no reason to believe this language means anything other than what it says; hence it appears that the DOE could not rely on this exception, regardless of when the designation was first published.
. The requirements of APA § 553 do not apply “when the agency for good cause finds (and incorporates the finding and a brief statement of reasons therefor in the rules issued) that notice and public procedure thereon are impracticable, unnecessary, or contrary to the public interest." 5 U.S.C. § 553(b)(B). The statute also provides that the 30-day publication requirement is waived “for good cause found [by the agency] and published with the rule.” 5 U.S.C. § 553(d)(3). The Rocky Flats designations published in the Federal Register do not contain any explanation for the failure to comply with APA § 553, and the DOE has not in its brief urged any justifications sufficient to excuse compliance.
. The terms “substantive rule” and “legislative rule,” used interchangeably by many authorities, refer to any rules which are subject to APA § 553. “Interpretative rules” and “general policy statements,” although similar, are distinguishable for some purposes. The Attorney General’s Manual on the Administrative Procedure Act (1947) gives these definitions:
Substantive rules — rules, other than organizational or procedural .. . issued by an agency pursuant to statutory authority and which implement the statute .... Such rules have the force and effect of law.
Interpretative rules — rules or statements issued by an agency to advise the public of the agency’s construction of the statutes and rules which it administers.
General statements of policy — statements issued by an agency to advise the public prospectively of the manner in which the agency proposes to exercise a discretionary power.
Id. at 30 n.3.
. The majority’s reliance on the public property exception to the APA’s notice and comment requirements is completely unfounded. See note 11, supra.
. The testimony taken at the motions hearing shows that the trespassing prohibition was posted clearly and conspicuously, in conformity with 10 C.F.R. § 860.6, at intervals along the boundary of the area restricted by the April 13 notice. In addition, the demonstrators were warned before the actual trespasses and arrests that they would be arrested and prosecuted if they persisted.
. The interrelationship of the APA § 553(d) delayed effectiveness requirement and the actual notice exception to § 552(a) has not been effectively delineated. The Attorney General has explained that “[t]he purpose of the time lag required by [§ 553(d) ] is to ‘afford persons affected a reasonable time to prepare for the effective date of a rule or rules or to take any other action which the issuance of rules may prompt.’ ” Attorney General’s Manual on the Administrative Procedure Act 36 (1947) (quoting S.Rep.No.752, 79th Cong., 1st Sess. 15 (1945); H.R.Rep.No. 1980, 79th Cong., 2d Sess. 25 (1945)). This purpose, in contrast to a purpose of merely insuring that affected parties learn of the rule’s promulgation before its effective date, is not realized if rules are immediately effective against persons with actual notice. There is authority suggesting that actual notice does not negate the 30-day delay required for legislative rules. See Hotch v. United States, 212 F.2d 280, 283-84 (9th Cir. 1954). In Lewis-Mota v. Secretary of Labor, 469 F.2d 478 (2d Cir. 1972), the court insisted that finding the directive in question to be a legislative rule that should have been issued in accordanee with § 553 made it unnecessary to consider whether the appellants had actual notice sufficient to excuse failure to publish under § 552. 469 F.2d at 481. The directive was declared invalid until 30 days after it was actually published in the Federal Register. Id. at 482.
. In addition to the procedures of the APA, the DOE must comply with the administrative procedure requirements established by Congress specifically for the DOE in the Department of Energy Organization Act, 42 U.S.C. § 7191. The DOE is therein required to allow at least 30 days following publication of a proposed rule in the Federal Register before the rule may be promulgated. 42 U.S.C. § 7191(b)(1). This duty is imposed on the DOE “in addition to” the requirements of the APA. Id. Accordingly, even if the actual notice exception of APA § 553(b) excused the agency from compliance with that section’s notice requirement, the agency still has the obligation to provide 30 days notice of proposed rulemaking under 42 U.S.C. § 7191(b)(1). That section contains no actual notice exception.
