Opinion for the Court filed by Circuit Judge STEPHEN F. WILLIAMS.
Having won his case before an administrative law judge, a social security claimant saw certain retroactive benefits recalculated and reduced by the Appeals Council of the Social Security Administration. He attacks this reduction on three grounds: that the Appeals Council lacked authority to reopen the AU’s decision on its own motion; that it improperly recalculated and reduced the amount of retroactive disability benefits; and that the SSA rules establishing the method for adjusting those benefits should have been subject to notice- and-comment and to publication under the Administrative Procedure and Freedom of Information Acts. The district court approved the Appeals Council ruling, and we affirm.
Allen Sheppard applied for Supplemental Security Income (“SSI”) and Social Security Disability Benefits in September 1981 and June 1982 respectively. These claims were denied at an initial level within the Social Security Administration both on first filing and on reconsideration. See Joint Appendix (“J.A.”) 16 (decision of Appeals Council Nov. 18, 1986). Sheppard successfully appealed the determination to an AU, who found him entitled retroactively to both types of payment. See id.; see generally Charles H. Koch, Jr., & David A. Koplow, *758 The Fourth Bite at the Apple: A Study of the Operation and Utility of the Social Security Administration’s Appeals Council, 17 Fla.State U.L.Rev. 199, 218-24 (1990) (describing claims process), reprinted from 1987 Admin.Conf. U.S. 629. The agency paid out almost $10,000 in SSI (through the District of Columbia's Department of Human Services, which deducted the amount of interim assistance it had extended Sheppard during the pendency of his federal claim), notifying Sheppard in the meantime that when his disability benefits were paid they would be offset by the SSI payments. The offset cut Sheppard’s retroactive disability benefit from more than $8000 to less than a hundred. He sought reconsideration of the reduction at the claims level but lost.
Sheppard again appealed to an AU, who again reversed, in January 1986, restoring the disability benefits to the unadjusted full amount. (So far as we can discern from the record, however, the larger amount was not paid.) In July the Appeals Council notified Sheppard of its decision to reopen the case for “good cause” under 20 CFR § 404.988(b) (1989), because the AU’s ruling was “erroneous on the face of the evidence”; and in November it formally reinstated the original determination to award only the reduced disability benefit. Sheppard took his case to district court, which upheld the reduction in benefits, see Memorandum and Order, No. 87-303 (D.D.C. June 16, 1989), and this appeal followed.
I
Sheppard first challenges the Appeals Council’s authority, under SSA regulations, to reopen the AU’s favorable ruling. He reads the regulations as providing for reopening only at the initiative of a claimant, arguing that SSA’s laxer interpretation would swallow parallel provisions providing for Appeals Council “review ” of AU rulings within a mere 60 days — as opposed to the four-year limit on reopening for “good cause” under § 404.988(b). Sheppard also asserts that the Appeals Council failed to meet the “good cause” threshold to which it held itself.
Inartful as the regulations may be, SSA’s interpretation of them is defensible. SSA regulations speak mostly to the claimants and thus are sprinkled throughout the “you” (signifying beneficiaries) and “we” (signifying the SSA). See 20 CFR § 404.901 (1989) (definitions of “we” and “you”). This style is apparently grounded in a belief that if regulations sound folksy they will be “clearer and easier for the public to use.” 45 Fed.Reg. 52,078 (1980) (stating purpose of revised SSA regulations); see also Note, Untangling “Operation Common Sense”: Reopening and Review of Social Security Administration Disability Claims, 87 Mich.L.Rev.1946, 1946 (1989). Introducing the procedure for reopening and revision, § 404.987(b) tells the reader that “[y]ou may ask that a determination or a decision to which you were a party be revised.” Nowhere in these provisions is the would-be beneficiary explicitly warned that the SSA may reopen on its own initiative.
But neither do the regulations exclude the possibility, and we think a fair reading allows it. Section 404.987(b) continues: “The conditions under which
we
will reopen a previous determination or decision are explained [below].” (Emphasis added.) Of course that could refer only to openings at the behest of a claimant, but it need not be so restricted. More significant is the inclusion of various conditions for reopening which in a great proportion of cases only the SSA would invoke. Determinations may be reopened at any time on a finding (among others) that the claimant committed fraud, that he was convicted of a crime bearing on the determination to be reopened, or that he murdered the person whose death payments the claimant stands to collect. See § 404.988(c). Sheppard argues that would-be beneficiaries might invoke these theories in order to increase their share of payments granted wholly or largely to others. This evidently is possible, but it seems implausible as the
exclusive
purpose of the provisions, with the counterintuitive effect of barring the SSA from revoking on its own, in the interest of
*759
the public fisc, payments made to defrauders, murderers and other criminals. See
Munsinger v. Schweiker,
Sheppard argues that if the reopening regulations, which permit reopening “for any reason” within 12 months of an initial determination, see § 404.988(a), apply to both sides, then the 60-day limit on seeking “review,” see 20 CFR §§ 404.968 & 404.969 (1989), is superfluous. Sheppard spots a violation of the canon requiring a distinct meaning for every provision of a regulatory structure. See
Chrupcala v. Heckler,
Quite apart from the canon’s heroic assumptions about the systematic and encyclopedic rationality of agencies, cf.
Fort Stewart Schools v. FLRA,
— U.S. -, -,
Sheppard responds that under the SSA’s reading of “good cause” this is no limit at all.

But two of the “good cause” provisions are plainly narrow, relating to new and material evidence and to clerical computation errors. 20 CFR § 404.989(a)(1) & (2). The third allows reopening where “[t]he evidence that was considered in making the ... decision clearly shows on its face that an error was made”. § 404.989(a)(3). While we accept the SSA view that this encompasses clear errors of law, see
Fox v. Bowen,
Finally we have a due process attack, which the First Circuit invoked as a basis for reading the regulations to preclude reopening on the Appeals Council’s initiative. See
McCuin,
As to finality, the First Circuit seemed to move directly from citation of cases

precepts of res judicata in administrative proceedings,

As to notice, we are a little mystified as to why it is “impossible]” for the SSA to give fair notice of reopening to claimants. See

In the face of six circuit court decisions to the contrary, Sheppard attacks the Appeals Council’s decision to require that retroactive SSI payments offset concur
*761
rently awarded disability benefits. See
Guadamuz v. Bowen,
When both types of income are paid as due, disability benefits reduce the amount of SSI. See 42 U.S.C. § 1382(c) (1988); 20 CFR §§ 416.1121(a) & 416.420 (1989);
Gallo v. Heckler,
We think it was. The statutory language by itself may not have required the offset; the old § 1320a-6 mandated reduction in retroactive disability benefits where the applicant “was an individual with respect to whom [SSI] benefits were paid ... for one or more months” overlapping the months for which disability benefits were sought. Sheppard argues that this offset requirement applied only when SSI benefits were paid as due. We assume that to be true for the explicit language, but that by no means suggests that offset is inappropriate when the agency makes the retroactive eligibility determination for both at the same time. The SSA’s approach, moreover, advances the express congressional purpose to prevent windfalls to retroactive beneficiaries. See
McKenzie,
This last conclusion dooms Sheppard’s final challenge: that SSA unlawfully failed to subject its calculation method — detailed in its “Program Operations Manual System” — to the notice and comment requirements of rulemaking under the Administrative Procedure Act, 5 U.S.C. § 553 (1988). Although § 553 explicitly exempts matters relating to “grants, benefits or contracts,” see § 553(a)(2), the Department of Health and Human Services has waived the exemption, see 36 Fed.Reg. 13,804 (1971). See Koch & Koplow,
Fourth Bite at the Apple,
17 Fla.State U.L.Rev. at 233 n. 187; cf.
Alcaraz v. Block,
In any event, as we believe the agency’s approach to have been the only reasonable one, Sheppard could not have been harmed by the absence of public participation. Aside from the point that disregard of the congressional resolution against windfalls would tend to help a very poor class of beneficiaries, see Brief for Appellant 40, there appear to have been no grounds on which to question the agency’s refusal to do so. The absence of any real argument, coupled with the logically related likelihood that we would reverse the SSA if it came out the other way, makes the absence of prejudice plain enough to find harmless any SSA error in not providing notice and comment.

Affirmed.
Notes
. The Appeals Council found that the "initial determination” for reopening purposes came with the decision (in 1985) on how Sheppard’s benefits would be computed once eligibility was established, J.A. 18, a finding petitioner does not challenge.
. Of course as noted the four-year limit runs from the date of initial determination, not the date of the ALJ’s decision. In cases considering challenges to own-motion reopening, the notification of intention to reopen has invariably followed, as in Sheppard's, within a matter of months from the date of the AU’s ruling. See
Fox v. Bowen,
. Sheppard also challenges SSA’s adjustment method as an alienation of disability benefits in violation of 42 U.S.C. § 407 (1988), insofar as his disability payment was offset by a SSI payment from which the D.C. government deducted the amount of interim assistance extended Sheppard. See
