742 F.2d 1561 | D.C. Cir. | 1984
Lead Opinion
Opinion for the Court filed by Circuit Judge WALD.
Dissenting opinion filed by Senior Circuit Judge BAZELON in which Circuit Judges TAMM and WILKEY join.
In this appeal, the General Motors Corporation (GM) challenges the authority of the Environmental Protection Agency (EPA or Agency) to require manufacturers, as a part of a recall pursuant to the Clean Air Act, to repair cars and engines, which are members of the recall class, but which have exceeded their statutory “useful lives” of five years or 50,000 miles at the time of repair. In 1980, the EPA promulgated what it termed an “interpretive rule,” embodying its consistent regulatory practice since the enactment of the Clean Air Act Amendments of 1970, requiring manufacturers to repair all members of a recall class, regardless of their age or mileage at the time of repair. Soon thereafter, in accordance with the interpretative rule, the agency ordered GM to submit a remedial plan for a class of recalled Cadillacs that included all class members regardless of age or mileage. In its petitions to this court, GM contends that (1) the EPA rule is a legislative, not interpretative, rule, and therefore the rule is void for failure to comply with the notice and comment procedures set down by the Administrative Procedure Act, and (2) in any event, the rule runs counter to the recall provision of the Clean Air Act and therefore is an invalid interpretation of the statute. GM consequently challenges the validity of both the interpretative rule and the agency order that applied the rule to the recall of GM automobiles. For the reasons stated below, we hold that the EPA rule is a valid interpretative rule, supported by the language, purpose and legislative history of section 207(c) of the Clean Air Act Amendments of 1970. We accordingly deny GM’s petitions.
I. Background
On March 21, 1977, after an EPA investigation and testing by both EPA and GM, the Administrator of the EPA notified GM pursuant to section 207(c)(1) of the Clean Air Act that the class of 1975 Cadillacs with type 230-carburetors did not conform with federal standards for carbon monoxide emission, and ordered GM to “submit a plan for recalling and remedying the nonconformity of the vehicles.”
Five weeks later, GM filed a proposed remedial plan for the 230-earburetor Cadillacs, and as a part of the plan offered to recall the 193-carburetor Cadillacs voluntarily.
At that time, however, GM urged the EPA to cancel the recall, arguing that “as a direct result of the delays incurred since our first remedial plan was submitted, a point of drastically diminished returns has been reached.” Letter from T.M. Fisher, Automotive Emission Control Director for GM, to Benjamin R. Jackson, EPA Deputy Assistant Administrator for Mobile Source and Noise Enforcement (Feb. 5, 1980), reprinted in J.A. at 258. More specifically, GM contended for the first time that “only those vehicles within the lesser of five years or 50,000 miles of operation at the time of presentation to the dealer for repairs will receive the [remedial repairs] at General Motors [sic] expense.”
On May 30, 1980, the EPA promulgated the rule at the center of dispute in this case. See 45 Fed.Reg. 36,396 (May 30, 1980). Under the rule, all remedial plans filed under section 207(c) of the Clean Air Act “shall provide that the manufacturer will remedy, • at the manufacturer’s expense, all properly maintained and used vehicles which experienced the nonconformity during their useful lives regardless of their age or mileage at the time of repair.” 40 C.F.R. Subpart S App. A (emphasis added). Applying this rule to the recall of the 1975 Cadillacs, the EPA on June 23, 1980, approved GM’s Cadillac remedial plan insofar as it applied to vehicles within their useful lives at the time of repair, and ordered GM to submit a plan for the repair of automobiles within the recall class “which failed or will fail to conform to applicable emission standards during their useful lives but will be beyond their useful lives at the time of repair.” Letter from Charles N. Freed, EPA Acting Assistant Deputy Administrator for Mobile Source, Noise and Radiation Enforcement, to T.M. Fisher, Director of Automotive Emission Control for GM (June 23, 1980), reprinted in J.A. at 263.
GM then petitioned this court, challenging both the May 30 rule and the June 30 recall determinations.
II. The EPA Rule Is an Interpretative Rule
EPA styled its May 30 rule as an “interpretive rule.” See 45 Fed.Reg. 36,396 (May 30, 1980). As a preliminary matter, GM challenges this characterization, contending that the May 30 rule is, on the
In a turn of phrase particularly apt in this case, the distinction between legislative and nonlegislative rules has been described as “enshrouded in considerable smog.” American Bus Association v. ICC, 627 F.2d 525, 529 (D.C.Cir.1980) (quoting Noel v. Chapman, 508 F.2d 1023, 1030 (2d Cir.1975) (discussing definition of “general statement of policy”)). Nonetheless, there are certain general principles that aid reviewing courts in making the determination whether a given rule is legislative or interpretative. First, the agency’s own label, while relevant, is not dispositive. See, e.g., Chamber of Commerce v. Occupational Safety and Health Administration, 636 F.2d 464, 468 (D.C.Cir.1980); Citizens to Save Spencer County v. EPA, 600 F.2d 844, 879 n. 171 (D.C.Cir.1979). An interpretative rule simply states what the administrative agency thinks the statute means, and only “ ‘reminds’ affected parties of existing duties.” Citizens to Save Spencer County, 600 F.2d at 876 & n. 153; ste also Chamber of Commerce, 636 F.2d at 469. On the other hand, if by its action the agency intends to create new law, rights or duties, the rule is properly considered to be a legislative rule. See, e.g., American Postal Workers Union v. United States Postal Service, 707 F.2d 548, 558-59 (D.C.Cir.1983); Citizens to Save Spencer County, 600 F.2d at 876.
In light of these general principles, we find that the May 30 rule constitutes an interpretative rule. We note, to begin with, that the agency regarded its rule as interpretative. See 45 Fed.Reg. 36,396 (May 30, 1980) (“Action: Interpretive Rule”). Moreover, EPA’s entire justification for the rule is comprised of reasoned statutory interpretation, with reference to the language, purpose and legislative history of section 207(c). See id. at 36,397-98. Indeed, the language of the rule itself indicates its interpretative nature. See 40 C.F.R. Subpart S App. A (“The purpose of this rule is to set forth EPA’s interpretation ... under section 207(c)(1) of the Clean Air Act....”) Finally, and most importantly, the rule did not create any new rights or duties; instead, it simply restated the consistent practice of the agency in conducting recalls pursuant to section 207(c).
Accordingly, we hold that the May 30 rule was an interpretative rule. The
III. The EPA Rule Is a Permissible Interpretation op Section 207
The EPA’s May 30 rule finds substantial support, and no contradiction, in the language and legislative history of section 207 of the Clean Air Act. Moreover, the May 30 rule effectuates important public policy goals embodied in the Act. Accordingly, we uphold the validity of the EPA rule at issue in this case.
The Supreme Court has recently outlined our proper task in reviewing an administrative construction of a statute that the agency administers. First, we must determine whether Congress “has directly spoken to the precise question at issue.” Chevron, U.S.A. v. National Resources Defense Council, — U.S. — at —, 104 S.Ct. 2778 at 2781, 81 L.Ed.2d 694 (1984). If the administrative construction
We begin our review with an examination of the statute. Section 207(c)(1) provides, in pertinent part:
If the Administrator determines that a substantial number of any class or category of vehicles or engines, although properly maintained and used, do not conform to the [EPA emission standards], when in actual use throughout their useful life (as determined under section 7521(d) of this title), he shall immediately notify the manufacturer thereof of such nonconformity, and he shall require the manufacturer to submit a plan for remedying the nonconformity of the vehicles or engines with respect to which such notification is given.
42 U.S.C. § 7541(c)(1). The EPA interprets this provision to authorize the recall of all members of a nonconforming class, except those not “properly maintained and used,” regardless of the age or mileage of any given member. We think the statute provides ample support for such an interpretation.
The statute requires manufacturers to submit remedial plans for “vehicles or engines with respect to which ... notification is given,” and directs the EPA Administrator to give such notification with respect to a “class or category of vehicles or engines,” a substantial number of which exhibited nonconformity during their useful lives. The statute thus provides for notice on a classwide basis and further requires the manufacturer to remedy all cars with respect to which such notice is given. In light of this class-based orientation of section 207(c)(1), we think the EPA reasonably mandated that remedial plans be designed to cover all members of a recall class. The agency reasonably required the manufacturers to include a ear or engine in their remedial plans if (1) a substantial number of cars within a given class exhibited nonconformity during their useful lives, and (2) the car is a member of that class. Section 207(c) affords an ample basis for this requirement.
GM nevertheless argues that individual vehicles and engines that have exceeded their useful lives cannot possibly exhibit a “nonconformity,” because the Clean Air
However, while it is true that the emission standards apply only to individual cars and engines during their useful lives, it does not follow that only those cars and engines within their useful lives may be recalled. Indeed, the question presented by this case is whether a member vehicle or engine of a recall class that has exceeded its useful life should nevertheless be repaired under section 207(c) at the manufacturer’s expense. That question is not settled by the definition of “useful life”; rather, it turns on the intended scope and purpose of the recall provision. As we have explained above, section 207(c) provides for classwide remedies of classwide defects. Accordingly, EPA reasonably reads the section to require the manufacturers to submit plans to “remedy the nonconformity” of the recall class. After all, a defective class — the members of which do not satisfy the emission standards during their useful lives — can be considered “nonconforming.” Hence the May 30 rule is not precluded by the statute’s definition of “useful life.”
Moreover, assuming arguendo that only individual cars and vehicles within their useful lives could exhibit a “nonconformity,” a plan “for remedying the nonconformity” could still include cars or engines beyond their useful lives at the time of repair. Through the recall scheme, Congress obviously intended the EPA to conduct tests on representative samplings of cars and engines, and to base its decision to recall on such tests.
The legislative history similarly supports EPA’s interpretative rule. The Report of the Senate Public Works Committee — upon which GM heavily relies, see infra at p. 1570 — refers to the recall of an entire “model or class” of vehicles or engines. S.Rep. No. 1196, 91st Cong., 2d Sess. 29 (1970). The Senate Committee bill designed two methods for EPA to assure in-use compliance with emission standards. First, after the development of a “quick test” method, the EPA could test the continuing compliance of “individual vehicles on the road.” Id. Alternatively, the EPA could conduct more intensive examinations of “representative samplefs] of a model or class,” and, after a finding of classwide noncompliance, EPA “could require the manufacturer to recall that model or class.” Id.; see id. at 111 (section 207 of S. 4358) (if EPA finds that “statistically representative samples of any class or category of vehicles or vehicle engines ... do not conform,” then all “vehicle engines included within the class or category” should be notified); id. at 62-63 (section-by-seetion analysis) after the EPA “discovers defects through testing” of a class of vehicles or engines, it “shall order the manufacturer to notify ... purchasers of the defect ”) (emphasis added).
Furthermore, when Congress revisited section 207(c) in 1977, the discussion assumed that the recall provision extended to all member vehicles or engines of the nonconforming classes. See, e.g., H.Rep. No. 294, 95th Cong., 1st Sess. 497, U.S.Code Cong. & Admin.News 1977, pp. 1077, 1459 (“if a substantial number of systems fail during their on-the-road operation, the EPA can recall the entire lot for repair at the manufacturer’s expense”); id. at 498, U.S. Code Cong. & Admin.News 1977, p. 1460 (noting the possibility of “a recall of all of that model vehicle or engine type”); 6 Environmental Policy Division of the Congressional Research Service of the Library for the Comm, on Environment and Public Works, 95th Cong., 2d Sess. 4540 (1978) (preliminary statement of Sen. Bentsen) (“section 207(c) authorizes the Agency to require the automaker to recall a ' given model run for needed repairs if the Agency determines that a substantial number of that model or engine type do not conform to the standards when in actual use”) (emphasis added); id. at 1220 (preliminary statement of Sen. Riegle) (“If a substantial number of systems fail during their on-the-road operation, the EPA can recall the entire lot for repair at the manufactur
Nonetheless, GM contends that one bit of legislative history contradicts the EPA’s interpretation. Specifically, GM heavily relies upon one passage from the Report of the Senate Public Works Committee. In discussing a provision that was the precursor to section 207 as finally enacted, the Report said: S.Rep. No. 1196, supra, at 31. GM believes that this passage constitutes a clear indication that Congress intended to limit the manufacturers’ recall obligations to exclude cars and engines beyond their useful lives.
The Committee also recognizes the difficulty in any recall provision of notifying the owners of vehicles. The Committee expects that the manufacturer would not only depend on the files of the franchise dealer, but would, to the extent practicable, use State motor vehicle department registration files to obtain the names and addresses of subsequent purchasers of cars. By establishing a 50,000 mile, no year lifetime for the purpose of warranty, the Committee did not intend to relieve the automobile manufacturers of their responsibility to notify owners of older cars. The 50,000-mile period can be assumed to be 4 to 5 years and the manufacturer should be expected to notify any owner of a vehicle that is five years old or less as to failure to continue to perform to the standard. A decision not to require the manufacturer to repair the vehicle could be made after notice and after finding that the vehicle had exceeded the 50,000-mile warranty period.
We disagree. In the first place, we would be very hesitant to overrule a reasonable agency interpretation, which enjoys support in the statutory language and other portions of legislative history, on the basis of a single, and rather ambiguous, passage from a committee report.
The Senate bill did not impose upon manufacturers any recall repair obligation; it provided only for the warranty repair obligation. Section 207(d)(2) of the bill merely directed the EPA to “order the manufacturer to provide prompt notification ... [to] purchasers of all ... vehicles or vehicle engines included in the class or category” that the EPA found to be in noncompliance with emission standards. See S.Rep. 1196,
However, the law as finally enacted, in contrast to the Senate bill, creates an independent recall repair obligation in addition to the warranty obligation. Section 7541(c) of title 42 requires the manufacturer of a recalled class to submit and comply with a remedial plan for that class. Unlike the warranty repair obligation, which covers only failure to conform with emission standards “for [the individual vehicle or engine’s] useful life,” 42 U.S.C. § 7541(a), the recall repair obligation contains no such limitation, and can reasonably be considered to extend to all vehicles or engines in the recall class. Thus, the passage from the Senate report explains an earlier version of section 207, which is irrelevant to the final version of the Act for the purposes of determining the scope of the recall repair obligation. We decline to overrule an otherwise reasonable agency interpretation on such an attenuated basis.
The EPA’s rule also furthers the purposes of the Congress. The Clean Air Act’s unequivocal directive is “to protect and enhance the quality of the Nation’s air resources so as to promote the public health and welfare and the productive capacity of its population.” 42 U.S.C. § 7401(b)(1). The May 30 rule obviously effectuates this purpose. When the EPA discovers a defect that results in excessive pollution in a class of cars or engines, the rule assures that the manufacturer must fashion a remedy to fit the violation: the remedial plan must include “all properly used and maintained nonconforming vehicles in the subject class regardless of their age or mileage at the time of repair.” 45 Fed.Reg. 36,397 (May 30, 1980).
This interpretation makes good practical sense because, no matter what their age at the time of actual recall, nonconforming cars have been riding the roads in violation of pollution standards. Before the EPA institutes a recall, it must make a determination that the members of the recall class have generally exceeded emission standards during their useful lives. See 42 U.S.C. § 7541(c)(1). The agency therefore may reasonably require manufacturers to include older cars and engines in their plans to “remedy the nonconformity” of the class. Cars and engines that failed to conform with emission standards during their useful lives do not cease to be a pollution hazard thereafter; in fact, it is sensible to presume that they are more likely to be a hazard afterward than conforming cars and engines.
IV. Conclusion
For the reasons stated above, we hold that the EPA’s May 30 rule is an interpretative rule. This rule enjoys adequate support in the language, purpose and legislative history of the Clean Air Act. GM’s petitions are therefore denied.
So ordered.

While it was and is the agency's policy to encourage voluntary recalls, the Administrator "fe[lt] compelled to issue th[e] order” because "General Motors’ acquiescence to recall comes at the end of more than two years of EPA investigation and GM opposition, and after assemblage of the most convincing case yet for recall."

. GM contends that its 1980 letter merely restated a position it had taken a year earlier in negotiations with the EPA. See GM Brief at 5. EPA, however, asserts that the letter represents "the first time that GM had proposed to impose a 5/50 [useful life] limitation on a remedial plan.” EPA Brief at 11. Nothing in the record shows that GM presented this limitation prior to its 1980 letter.
. On November 26, 1980, the EPA published a notice in the Federal Register declaring its partial approval and partial disapproval of GM’s remedial plan to be "final.” See 45 Fed.Reg. 78798 (Nov. 26, 1980). GM subsequently filed a protective petition, consolidated with its previous appeals, seeking review of this Federal Register notice.
. The APA exempts from its notice and comment procedures “interpretative rules, general statements of policy, or rules of agency organization, procedure, or practice.” 5 U.S.C. § 553(b)(A). Similarly, the Clean Air Act exempts from its special rulemaking procedures "any rule or circumstance, referred to in sub-paragraphs (A) or (B) of subsection 553(b) of title 5.” 42 U.S.C. § 7607(d)(1). Accordingly, interpretative rules are not subject to the procedural requirements set down by either the APA or the Clean Air Act.
. The dissent contests this proposition and calls it "a proposition upon which the majority places substantial weight.” Diss.Op. at 1574. At the outset, it should be made clear that this proposition is significant primarily in support of the conclusion that the EPA rule is interpretative, and not legislative, a proposition with which the dissent agrees. See Diss.Op. at 1573 & n. 3.
In its attempt to make light of the EPA’s historical adherence to its current interpretation, the dissent asserts that the EPA interpretation has only “a lifespan barely exceeding one year” because the sole controversy over the interpretation occurred in 1979. See Diss.Op. at 1574 n. 11. However, as the EPA observed when it issued its interpretative rule ”[i]n the past, manufacturers have not conditioned a vehicle’s eligibility for recall repair ... on the basis of the vehicle's age or mileage.” 45 Fed. Reg. at 36,397. Rather than diminishing the rule’s status as a longstanding EPA interpretation, the absence of any prior controversy over the repair of cars exceeding their useful lives demonstrates the reasonableness of the EPA’s interpretation of its own regulatory scheme. See, e.g., Esquire, Inc. v. Ringer, 591 F.2d 796, 801 (D.C.Cir.1978) (Bazelon, J.) (administrative interpretation deserves “controlling weight," particularly when it "has been consistently followed for a significant period of time”), cert. denied, 440 U.S. 908, 99 S.Ct. 1217, 59 L.Ed.2d 456 (1979); DeLano v. United States, 183 Ct.Cl.
The dissent mistakenly speculates that “manufacturers in previous recalls have failed to raise the question of liability for repair of cars beyond their useful lives because the involvement of such vehicles in the recalls has been de minimis." Diss.Op. at 1574 n. 12. The dissent here loses sight of the facts. Despite its view that "virtually all” of the recalls involved tiny percentages of older cars, in six out of the fifteen recalls described in detail in the record, see J.A. at 278-96, the EPA issued a recall notice to the manufacturer 34-55 months after the cars were on the market. Under EPA’s method of calculating the percentage of cars recalled that were beyond their useful lives, see J.A. at 275, these recalls involved large quantities of older cars. For example, the Pontiac recall, initiated in 1979, involved 1975 model year cars, 54% of which were beyond their useful lives. See J.A. at 293. Moreover, almost 30% of the 1976 Pontiacs involved in that recall had exceeded their useful lives at the time of manufacturer notice. Similarly, in 1978 EPA initiated a recall that included 1975 Fords, approximately 28% of which had exceeded their useful lives. See J.A. at 289. Also, in 1978 the EPA began a recall that included 1974 AMC cars sold in California, approximately 56% of which were beyond their useful lives. See J.A. at 291-92. Any manufacturer who "prophetically foresaw” the dissent’s position, Diss.Op. at 1574 n. 12, believing these recalls exceeded the legal scope of coverage, could reasonably have been expected to make an objection.
Moreover, at least three other recalls included substantial numbers of olders cars. See J.A. at 280 (1974 Pontiacs; approximately 22% beyond useful lives); J.A. at 288 (1975 Fords; approximately 16% beyond useful lives); J.A. at 296 (1977 Buicks; approximately 28.5% beyond useful lives).
The dissent obfuscates the issue by claiming that the above discussion ”neglect[s] the fact” that some of these recalls included younger cars in addition to older cars, and that the "AMC recall was complicated by the more stringent emissions standards” applicable only in California. Diss.Op. at 1574 n. 12. However interesting, these details are irrelevant to the dissent’s assertion that the manufacturers "failed to raise the question of liability for repair of cars beyond their useful lives because the involvement of such vehicles in the recalls has been de minimis." Id. The recall of younger cars in addition to older cars in no way detracts from the fact that there were substantial numbers of older cars involved in these recalls. The relevance of the California air emission standards to the dissent’s position is at best obscure.
In a final aside, the dissent invokes the fact that "owner responses to recalls drop dramatically with the age of the vehicle." Id. Such statistical sport, however, ignores the fact that the manufacturer incurs heavy costs — both financial and good will — simply by issuing its notice to owners. Moreover, while the response rate declines as time goes by, the percentage of older cars in the recall sales rises commensurately. See J.A. at 275, 298. Therefore, whatever the age of the recall class, the manufacturer would still have a substantial stake and ample incentive to raise the useful life issue.
In sum, the dissent fails in its attempts to transmogrify the absence of controversy over the EPA’s policy into the absence of any EPA policy on the useful life limitation. Taken individually or cumulatively, the dissent's efforts to invent post hoc rationalizations for the manufacturers’ failure to challenge the EPA’s policy are similarly unconvincing. The EPA has consistently approved only those remedial plans that included all cars and engines in the recall class, regardless of their age or mileage. It therefore constitutes a longstanding administrative policy.
. It is difficult to square the dissent’s position with these recent pronouncements by the Supreme Court. Although the dissent attempts to invoke the "plain meaning of the statute,” Diss. Op. at 1576, in truth it argues only that the useful life limitation should be imported into the recall provision. See id. at 1575-1576. However, nothing in the language or legislative history of the recall provision compels this result. See infra at pp. 1578-1580. The absence of a useful life limitation in the recall provision should be compared with the express limitation of the manufacturer’s liability under the warranty provision to emissions violations occurring during a vehicle’s "useful life.” Compare 42 U.S.C. § 7541(c)(1) (recall provision) with id. § 7541(a) (warranty provision). See infra at pp. 1570-1571.
Similarly, the dissent's extensive dicta, setting out what it dubs "some reasonable alternatives,” see Diss.Op. at 1582-1584, is particularly inappropriate in light of the Supreme Court’s recent warning that reviewing courts should respect the policy choices of administrative agencies. See Chevron, slip op. — U.S. at —, 104 S.Ct. at 2793-94. The question presented today is whether the agency’s action is a reasonable one in light of the existing statutory constraints, and it is not the job of the courts to propose rules that they would prefer the agency to adopt.
. The dissent erroneously concludes that the EPA rule "would expose the manufacturer to liability for repair virtually indefinitely." Diss.Op. at 1579. The statute, however, authorizes the Administrator to institute a recall only after determining that a substantial number of vehicles or engines in the class "do not conform to the [emission standards] when in actual use throughout their useful life." 42 U.S.C. § 7541(c)(1) (emphasis added). Since cars and engines older than five years of age are no longer within their useful lives, this statutory condition cannot be met "indefinitely." There is, at the very least, this definite time limitation on the Administrator: he must conclude his testing before the entire recall class has exceeded five years of age.
Moreover, special problems might arise when a proposed recall class includes numerous model years of a particular car or engine, some of which have entirely exceeded their useful lives at the time the EPA conducts its testing. See Diss.Op. at 1579 (hypothesizing such a class). The design of some features of a class of cars or engines might be altered from one model year to another. If these changes could affect the level of auto emissions, then the EPA’s testing of only the models within their useful lives might not be conclusive as to the nonconformity of the entire class proposed for recall. However, since the recall class presented in this case does not raise this problem, we need not decide this hypothetical. Suffice it to say that our reading of the statute amply permits the EPA to recall cars and engines regardless of their age at the time of recall. We do not address today the possible constraints upon the EPA in defining the reasonable scope of a recall class.
. At oral argument and in its supplemental brief, the EPA attested to its flexibility in devising appropriate and reasonable remedial schemes for older cars and engines. We do not find, and GM does not contend, that the remedy
. The dissent complains that “the EPA’s rule establishes an absolute and irrebutable presumption that all older cars were among the percentage failing to meet standards during their useful lives." Diss.Op. at 1582. However, it is the statute that establishes the presumption that the cars and engines within a class exhibiting substantial nonconformity are individually nonconforming. Moreover, this presumption is not "absolute and irrebuttable”; the manufacturer is free to come forward with evidence that an individual car or engine, or a particular subclass of cars and engines, were in fact conforming during their useful lives. The results of on-the-road testing would be particularly relevant to this inquiry.
This same proof problem, of course, would be present in the implementation of the dissent’s proposal to permit the Administrator to recall cars and engines that were within their useful lives at the time of the notice of nonconformity. Under this proposal, manufacturers would be required to repair cars and engines exceeding their useful lives without any showing that the particular cars or engines had violated the emission standards during their useful lives. The dissent’s proposal, to be practical, must also follow the statutory presumption that members of the recall class were nonconforming during their useful lives.
. In addition, EPA’s class-based interpretation of section 207 enjoys precedential support. This court, in one of the few judicial cases to construe the recall provision, observed that "[ujnlike the discovery and cure of nonconformity of individual vehicles under the warranty provisions, the remedy at this stage is recall of the entire class of vehicles in order to correct the design, material, or workmanship defect.” Chrysler Corp. v. EPA, 631 F.2d 865, 868 (D.C.Cir.) (emphasis in original), cert. denied, 449 U.S. 1021, 101 S.Ct. 589, 66 L.Ed.2d 483 (1980).
. As this court, sitting en banc, observed:
[I]t must be remembered that committee reports are not the law; they are only aids in interpreting statutory language and are useful only to the extent they fairly reflect congressional intent. Sometimes committee reports are not reliable guides to legislative intent, as, for example, where they contain statements that contradict the plain meaning of the statutory language or that conflict with the expressed purpose of the statute.
Jordan v. United States Dep’t of Justice, 591 F.2d 753, 767 (D.C.Cir.1978) (en banc) (footnotes omitted).
. The dissent maintains that Congress "clearly intended to avoid” the prospect that "ten-year old vehicles would be required to conform” with the emission standards. See Diss.Op. at 1580 & n. 40. However, such "ten-year old vehicles" are vehicles that were not in conformity with the emission standards during their lives, and accordingly they should not be excluded from the recall of the class of which they are mem- ’ ers. See supra at pp. 1567-1568.
Moreover, the dissent’s own proposed alternative would entail the repair of “ten-year old
. The EPA explained with specificity the purposes of section 207 when it promulgated the interpretative rule and warned that those purposes could be undermined in the absence of the rule:
The recall program has two objectives: 1) To assure that manufacturers repair vehicles which are exceeding the emission standards if maintained and used and the non-conformity occurs within the useful life of the vehicles, and 2) to encourage manufacturers to build durable emission-related components to assure that vehicles will not manifest excessive emissions during their useful lives. Both of these objectives are frustrated by an interpretation of useful life which limits manufacturers’ liability only to vehicles which are within their useful life at the time of repair.
45 Fed.Reg. at 36,397. As this court stressed only recently, ”[w]e cannot interpret section 207 ‘in a manner which runs counter to the broad goals which Congress intended it to effectuate.’ ’’ Chrysler Corp. v. EPA, 631 F.2d at 888 (quoting FTC v. Fred Meyer, Inc., 390 U.S. 341, 349, 88 S.Ct. 904, 908, 19 L.Ed.2d 1222 (1968)).
. As the EPA emphasized when issuing the interpretative rule, "interpreting section 207(c)(1) as imposing a useful life limitation on vehicles eligible for repair under a remedial plan could severely limit the number of nonconforming vehicles repaired pursuant to recall orders, could seriously impact ambient air quality, and would frustrate the intent of Congress.” 45 Fed.Reg. 36,398.
The dissent argues that the EPA could have devised an alternative administrative scheme, using its legislative rulemaking powers, to "toll” the useful life of vehicles either at the time the EPA initiates the recall or during any period of delay that could be attributed to manufacturer failure to comply in a timely manner with its statutory or regulatory obligations. See Diss.Op. at 1582-1583. Under such a scheme, only those cars within their useful lives at the time of the initial EPA notice of recall would be repaired at the manufacturer’s expense. However, under the scheme, manufacturers could not cause attrition in the class size by engaging in dilatory tactics.
We decline to enter into the inquiry of which regulatory scheme would best balance all the interests in this field. Our task here is merely to determine whether the agency's interpretation is "sufficiently reasonable,” and we conclude that it certainly is. See FEC v. Democratic Senatorial Campaign Comm., 454 U.S. 27, 39, 102 S.Ct. 38, 44, 70 L.Ed.2d 23 (1981). Regardless of whether such interpretations as the dissent suggests would be permissible — an issue we need not reach today — they are in fact not the interpretation that has been adopted by the agency. Moreover, courts should pay special deference to an agency’s interpretation when, as here, (a) the agency is interpreting a statute it is charged with administering, (b) the interpretation has been consistently adhered to, (c) Congress has acquiesced to the administrative interpretation, and (d) the statute gives the agency substantial discretion in administering and designing an enforcement scheme. See National Wildlife Fed'n v. Gorsuch, 693 F.2d 156, 166-69 (D.C.Cir.1982).
Dissenting Opinion
dissenting.
The interpretative rule upheld by the court today enjoys the virtues of simplicity,
I. “Useful Life” and the Limits of Interpretation
A. The Standard of Review
We are called upon in this case to review an interpretative, not a legislative rule.
The Supreme Court has pointed out that “[ojrdinarily, administrative interpretations are given important but not controlling significance.”
The EPA rule does not “receive high marks when judged by [these] standards ____”
B. Statutory Language
In reviewing an agency’s interpretation of a statute, a court should first examine the language of that statute to determine whether the interpretation falls within the statute’s plain meaning.
If the Administrator determines that a substantial number of any class or category of vehicles or engines, although properly maintained and used, do not conform to the regulations prescribed under section 7521 of this title [emissions standards] when in actual use throughout their useful life (as determined under section 7521(d) of this title), he shall immediately notify the manufacturer thereof of such nonconformity, and he shall require the manufacturer to submit a*1576 plan for remedying the nonconformity of the vehicles or engines with respect to which such notification is given. The plan shall provide that the nonconformity of any such vehicles or engines which are properly used and maintained will be remedied at the expense of the manufacturer.16
The majority relies upon “this class-based orientation of section 207(c)(1)” in concluding that “the EPA reasonably mandated that remedial plans be designed to cover all members of a recall class,” regardless of the age or mileage of any individual vehicle at the time it is brought in for repair, “if (1) a substantial number of cars within a given class exhibited nonconformity during their useful lives, and (2) the car is a member of that class.”
To some extent, of course, the plain language of a statute and the legislative history which resulted in that language are inextricable;
But if defining the concept of “useful life” cannot settle this question, neither will minimizing that concept’s obvious importance contribute to the correct resolution of this case. Indeed, it is likely that the “intended scope and purpose of the recall provision” can only be arrived at and fully appreciated by attempting to define, understand, and reasonably apply that critical statutory term. A good place to begin is with the argument urged upon this court by GM, the bulk of which the majority properly rejects.
In asserting that “the statute does not authorize EPA to order recall and repair of vehicles beyond their useful lives, ignoring their age and mileage at the time of repair,”
C. The Legislative History
Even where, as here, the statutory language appears clear, the plain meaning rule is only a primary and not a conclusive
If little else is crystal clear from the complex legislative history of the Clean Air Act, one thing is: despite evidence that the actual life of an automobile is closer to ten years or one hundred thousand miles than it is to five years or fifty thousand miles, Congress intentionally limited the duration of a manufacturer’s liability for a vehicle’s nonconformity with emissions standards to a five-year/fifty-thousand mile period. For example, Senator Muskie, one of the bill’s prime sponsors, remarked that “[fjifty thousand miles is not all their life, 100,000 miles being nearer to a measure of the life of a motor vehicle, but we have taken 50,000 miles.”
The actual life of a car is more than 50,000 miles. We all know that. It approaches 100,000 miles, I think, increasingly, but it was our feeling that a 50,-000-mile warranty would put sufficient pressure on the manufacturers to meet the standards so that if they met them for 50,000 miles, the chances were that the standards would be met pretty closely ... even ... beyond 50,000 miles.31
The considerations underlying the “useful life” limitations were equally straightforward. As the Senate Committee Report noted in 1970:
The manufacturers informed the Committee that they would not be able to guarantee conformity with emissions standards for the anticipated 10-year life of a vehicle. The committee bill provides that 50,000 miles would be the maximum that a vehicle would be required to conform to the standards for which it was certified.32
Where Congress has so explicitly and deliberately considered, and then rejected, a more expansive requirement than that ultimately enacted, it is not for the agency to exceed the statutory limits under the guise of “interpretation.”
Nevertheless, the majority argues at considerable length that some of the 1970 legislative history is “irrelevant” because
*1579 the law as finally enacted, in contrast to the Senate bill, creates an independent recall repair obligation in addition to the warranty obligation. Section 7541(c) of title 42 requires the manufacturer of a recalled class to submit and comply with a remedial plan for that class. Unlike the warranty repair obligation, which covers only failure to conform with emission standards “for [the individual vehicle or engine’s] useful life,” 42 U.S.C. § 7541(a), the recall repair obligation contains no such limitation, and can reasonably be considered to extend to all vehicles or engines in the recall class.34
With respect, such exertions in response to GM’s reliance upon a particular passage from a committee report hardly seems worth the candle.
To appreciate how un reasonable such an interpretation would be, it is important to bear in mind that a recall class may include vehicles or engines of more than one model year. For example, the same carburetor or engine component may be used in vehicles over the course of four or five model years.
One would have expected such a drastic extension of the manufacturer’s repair obligation to have attracted at least some debate. Certainly there were those in the Senate who believed even the limited five-year liability imposed by the warranty provision to have been excessive.
My own reading of the legislative history leads me to conclude that any alterations made in the Senate bill by the Conference Committee were merely “technical, clarifying, and conforming changes,”
If this reading of the legislative history (and, as demonstrated earlier, of the plain meaning of the statutory language with which the history is thoroughly consistent, is correct, just one task remains: the determination of the precise point in the recall process at which the all-important “useful life” limitation should apply. That determination, of course, is for the agency, so long as its action is “sufficiently reasonable.”
II. The Reasonableness Inquiry
A. The Language of the May 30 Rule and its Implications
By requiring “manufacturers to submit a plan to remedy all vehicles within the class or category of vehicles subject to an ordered recall which experienced the nonconformity during their useful lives regardless of their age or mileage at the time of repair,”
Under the May 30 rule as promulgated, whenever a car brought in for repair has exceeded its useful life, the manufacturer will be unable to demonstrate whether a present emissions excess is attributable to the sanctioned erosion of performance after 5 years or 50,000 miles, which Congress so clearly acknowledged as likely and explicitly provided for through the concept of useful life, or to a nonconformity which did in fact exist during the vehicle’s useful life.
B. Some Reasonable Alternatives
In concluding that the agency acted unreasonably in promulgating its May 30 interpretative rule, I wish to emphasize that the interpretation urged upon this court by GM seems to me at least equally unreasonable,
First, EPA might reword its interpretative rule in such a way as to reasonably interpret the language and history of the recall provision. If, for example, the rule were to provide for the recall and repair of vehicles within their useful lives at the time the notice of nonconformity issued to manufacturers, the intent of Congress would be vindicated, and manufacturers would have little or no incentive to delay a valid recall by means of strategic lawyering. Quite to the contrary, any frivolous or bad-faith delay would be penalized not only by its inherent expense but by the fact that any nonconforming vehicles ultimately requiring repair would be older and, pre
The reasonableness of such an interpretative rule would be underscored by an important passage of the Act's legislative history. The comments of the House managers of the 1970 bill, included in the Conference Committee Report, explicitly state:
The Senate [bill] ... authorized the Administrator, if he determined that any class or category of vehicles or engines did not conform with applicable emission standards, to require manufacturers to notify purchasers of such nonconformity. Moreover, if a manufacturer discovered such nonconformity during the term of any warranty required under the Senate [bill], he was required to notify purchasers of the nonconformity and to remedy such nonconformity at no cost to the owner.57
Even as to the warranty provision, then, and a fortiori as to the recall provision (if, as the majority believes, there is any distinction between the two), Congress contemplated that the notion of “useful life” was to be applied at the time the manufacturer became aware of a nonconformity.
A second alternative open to the agency, as noted, would be a full legislative rule-making. If, after hearing all sides and making a record, the agency believed that the language of its May 30 rule remained justifiable, it would be sustained on judicial review unless it were found to be “arbitrary, capricious, or manifestly contrary to the statute.”
In this context I would note, as well, that the Administrator has substantial discretion in defining by regulation the useful lives of vehicles under the Act. Section 202(d) defines the useful lives of “light duty vehicles” as “a period of use of five years or fifty thousand miles (or the equivalent), whichever first occurs____”
Finally, of course, the EPA and other advocates of a more far-reaching recall authority than that provided by Congress in the Act as amended may seek fresh congressional attention to the issues raised by this case. A more reasonable interpretative rule, crafted along the lines suggested in this opinion, may be deemed inadequate; similarly, the alternative of legislative rule-making may prove somehow unsatisfactory. If so, those who would impose a more far-reaching burden upon automobile manufacturers to ensure the purity of our nation’s air will have recourse to our nation’s legislators. It may well be desirable to hold manufacturers liable to recall and repair every vehicle ever produced that may have violated emissions standards many years before in order “to compensate for the pollution caused during the time of its violation.”
III. Conclusion
For the reasons discussed in this opinion, I would vacate EPA’s May 30, 1980 interpretative rule. I would affirm, however, that part of the June 23,1980 order finding that GM had failed to submit a satisfactory remedial plan with respect to certain 1975 Cadillacs within their useful lives as of March 21, 1977, the date on which the Administrator officially notified GM of the nonconformity of a substantial number of those vehicles.

. EPA argues, and the majority agrees, that its interpretation is "longstanding." Maj. op. at 1565 n. 7. Yet, with the exception of the dispute with GM leading to the promulgation of the May 30 rule, the agency can point to only one controversy, a Chrysler recall in 1979, during which the "useful life” issue arose. See EPA Brief at 5 & n. 5. In that case, by EPA’s own admission, the agency did not press the issue with Chrysler, because the question of nonconformity was itself being litigated. See id. Thus, even assuming that a lifespan barely exceeding one year suffices to render an interpretation longstanding, it would appear that the public was never placed on notice with respect to EPA’s interpretation. To the extent to which the Supreme Court has required that courts scrutinize the timing of an agency’s interpretative rulemaking, EPA’s promulgation of the May 30 rule while in the heat of regulatory battle with GM deserves close and critical attention.
. Maj. op. at 1565; see also id. at 1563; 1565 n. 7; 1570 n. 12. This conclusion lacks sufficient specific support in the record. Outside of the instant dispute, as noted supra, the EPA can point to only the Chrysler recall in February 1979, and there the useful life issue was conceded by the EPA. See EPA Brief at 5 & n. 5. Thus, in the only two specific instances in which the useful life limitations were at issue, the EPA ultimately acceded to the limitation in the Chrysler recall, choosing for the first time to contest the limitation in this present Cadillac recall.
The majority also speculates that the EPA’s practice must have been consistent because the "manufacturers have not conditioned a vehicle’s eligibility for recall repair ... on the basis of the vehicle's age or mileage.” Maj. op. at 1565 n. 7 (citing 45 Fed.Reg. at 36,397). The record simply fails to substantiate directly that the manufacturers’ behavior was the result of the imposition of the EPA’s practice. The majority’s speculation in fact appears to presume that manufacturers (1) somehow foresaw EPA’s heretofore unannounced interpretation of their liability for repair of vehicles beyond their useful lives; (2) conceded the "reasonableness” of EPA’s position; and (3) therefore, "voluntarily” included older vehicles in their remedial plans, refraining from challenging this manifestly "reasonable" interpretation.
A more plausible explanation suggests itself. With the exception of the Chrysler and Cadillac recalls in which the useful life disputes did arise, virtually all completed emission recalls have involved vehicle classes less than three years of age at the time of owner notification of nonconformity by the manufacturer. See J.A. 278-96. The owner response rates drop substantially for vehicles more than four years old. See id. at 298. This information forms a strong basis for the inference that both the EPA and manufacturers in previous recalls have failed to raise the question of liability for repair of cars beyond their useful lives because the involvement of such vehicles in the recalls has been de minimis. It would not have been economical for manufacturers to have expended the resources necessary to identify those vehicles beyond their useful lives or to risk owner alienation by refusing to repair the small percentage of older cars which might have found their ways to dealerships in response to a recall.
When the "six out of fifteen recalls described in detail in the record” and cited by the majority, Maj. op. at 1565 n. 7, are closely examined, this conclusion is reinforced. The percentages relied upon neglect the fact, for example, that the recalls of 1975 and 1976 Pontiacs, 1975 Fords, and 1974 AMCs involved vehicles that were part of a much larger (and younger) recall class; that the AMC recall was complicated by the more stringent emissions standards applicable uniquely to vehicles sold in California; that the manufacturers included older vehicles voluntarily; that owner responses to recalls drop dramatically with the age of the vehicle; and that the idiosyncracies of particular recalls and of negotiations between EPA and manufacturers on a case-by-case basis render the statistics relied upon by the majority unrepresentative and misleading. See J.A. at 278-96.
For example, the majority writes that "in 1978 the EPA began a recall that included 1974 AMC cars sold in California, approximately 56% of which were beyond their useful lives.” Maj. op. at 1565 n. 7 (emphasis in original). A close look at the facts of that recall, however, is illuminating. EPA ordered the recall of all 1976 AMC cars in May 1978. At that point, the model was approximately two-and-a-half years old and fewer than 20% of the vehicles could have been
The majority’s reliance upon a few other recalls involving some percentage of olders cars is similarly misplaced, but no constructive purpose would be served by here disputing the numbers offered by the majority or by enumerating the special circumstances involved in each case. The fact remains that nine of the fifteen recalls involved no older vehicles, J.A. at 278-96, and that only the Chrysler and Cadillac recalls meaningfully presented the useful life issue, an issue which, in the Chrysler case, was not pursued by EPA. See supra note 11. Such a history hardly “constitutes a longstanding administrative policy.” Maj. op. at 1565 n. 7.
Judicial deference to an agency’s "consistent” interpretation should not be based on the fact that the issue at stake simply has not previously arisen. Such deference is appropriate if an administrative interpretation has been consistently asserted in the face of a long series of challenges, see, e.g., Esquire, Inc. v. Ringer, 591 F.2d 796, 801 (D.C.Cir.1978), or if the policy had been publicly announced and implemented for a long time, see, e.g., DeLano v. United States, 183 Ct.Cl. 379, 393 F.2d 517, 521-22 (1968). In the instant case, however, the EPA has previously announced its position only once and, in that instance, "did not proceed” on behalf of that position. EPA Brief at 5 n. 5. We are pointed to no other occasion on which the EPA affirmatively required manufacturers to include vehicles beyond their useful lives in their remedial plans; the issue simply was never raised by either party.

. GM essentially ignores the language of section 207(c) itself, which plainly invokes the "useful life" concept in connection with the EPA’s pre-notice determination of nonconformity. The company argues instead that vehicles beyond their useful lives when brought in for repair cannot be, at that time, "nonconforming,” since emissions standards can only apply to vehicles during their useful lives. GM Brief at 19-20, 23-26. If accepted as a reasonable interpretation of the statute, EPA would be required, before issuing a notice of nonconformity to a manufacturer, to estimate and take into account potentially long lag times between that notice and the date that the entire class of vehicles would be brought in for inspection and repair. In practical administrative terms, the five year element of "useful life” might mean 4!/2 years in some cases, two years or less in others. Section 207(c) would become an uncertain and inconsistent mechanism at best, a nullity at worst. Reading the statute, instead, to mean what it plainly seems to mean — i.e., that a manufacturer must recall and repair vehicles that are within their useful lives at the time that the agency’s notice of nonconformity first issues — would be at once administerable and reasonable.

At one point the majority appears to modify its own "classwide" analysis, arguing that “[tjhere is, at the very least, this definite time limitation on the Administrator: he must conclude his testing before the entire recall class has exceeded five years of age.” Maj. op. at 1568 n. 9. While I agree that this would be a slightly more reasonable interpretation of the EPA’s statutory authority, it is not the authority asserted by the EPA in this case, and no hint of such a limitation is contained in the plain language of the interpretative rule, the validity of which is here at issue. Additionally, it does not avoid the unreasonable result illustrated infra notes 37-41 and accompanying text.
. See, e.g., J.A. 293 (recall of 1975-1978 Pontiacs with EGR back pressure transducers).
. Thus, if the Pontiac engine defect, supra, for instance, had been discovered during the fourth year of the useful lives of the 1978 model Pontiacs, all Pontiacs manufactured with the suspect transducer would be subject to recall. The manufacturer would have been required to repair not only the four-year old 1978 but also the 1975 Pontiacs, which, at the time the EPA would have issued its notification of nonconformity, would have been between nine and ten years old.
. Months may be consumed in testing and investigating a potentially nonconforming class prior to the issuance of a recall order. EPA approximates the average time spent in such investigations as nine months. See J.A. 268 & n. 5. In this case the EPA investigation began in May 1975, issued its notice of nonconformity in March 1977, and negotiated the details of GM’s remedial plan through December 1979. See J.A.
. EPA estimates that the “average time from recall order to owner notification is 8‘A months.” EPA Brief at 28 n. 33; J.A. 268 & n. 6. As to appeals, EPA found "the recall of certain 1975 Chryslers ordered recalled on December 8, 1976” to be “[o]f particular note”:
Although the recall was ordered relatively early in the life of the vehicles, Chrysler requested an administrative hearing on the Administrator’s determination of nonconformity. The Administrative Law Judge upheld the determination in a decision filed on February 10, 1978. Subsequent appeals to the Administrator and this Court also resulted in decisions favorable to EPA. Chrysler Corp. v. EPA, [631 F.2d 865 (D.C.Cir.1980) ].... Certiorari was denied by the U.S. Supreme Court on December 1, 1980 ..., when few, if any, of the 208,000 vehicles subject to the recall order were still within their useful lives.
EPA Brief at 28 n. 35.
. If the EPA and this court had interpreted the statute to require the manufacturer to recall and bring into conformity with "useful life” standards all cars which were within their useful lives at the time the notice of nonconformity issued to manufacturers, or even on the date the manufacturer and EPA agreed on an appropriate remedial plan, that interpretation would, 1 believe, have been a reasonable one. This is so even though, as. developed infra note 58 and accompanying text, such an interpretation might require some vehicles to be brought into conformity with such standards despite their having exceeded their useful lives at the time of repair. By limiting, ab initio, the recall authority to the class of vehicles within their useful lives at the time the nonconformity is first established by the agency and communicated to the manufacturer, the agency would have been acting, in my opinion, within its reasonable discretion under the statute. See infra pp. 1582-1583.
Taken on its face, however, the EPA rule simply goes too far, and does raise the specter of a manufacturer being required to remedy decade-old cars at its own expense, a result that Congress clearly intended to avoid. The EPA attempted at oral argument to salvage the rule from this conspicuous defect by asserting that the agency will not in fact require such vehicles to be brought into compliance with inapplicable standards but will instead require the same “repair” to be made on older and younger vehicles. The difficulty with this approach is that the Act requires not that a "repair” be performed but that a nonconformity be remedied.
Similarly, the majority’s attempt to save this interpretative rule by reading a modest limitation into its facially limitless language, Maj. op. at 1568 n. 9, ought to be unavailing. Even if the recall action in this case can and should be upheld, see infra at p. 1584, the rule itself, as promulgated, is clearly and unambiguously contrary to the statute’s language and history.
Under our cases, if the agency wishes to fill in interstices created by a possible congressional failure to anticipate all the possible consequences of the statutory scheme, the proper recourse is a legislative, not an interpretative rule. See Chamber of Commerce v. OSHA, 636 F.2d 464, 469-70 (D.C.Cir.1980).

. The majority has, in a sense, suggested a fourth. See supra note 36; Maj. op. at 1568 n. 9. In so doing, however, the majority opinion insists that "it is not the job of the courts to propose rules that they would prefer the agency to adopt." Maj. op. at 1567 n. 8. That is true, of course, but it is equally true, and this court has recently reemphasized, that where the adoption of a particular rule is beyond the agency's statutory authority, it is our obligation to vacate the rule in question. Cf. Union of Concerned Scientists v. Nuclear Regulatory Comm'n, 735 F.2d 1437, 1451 (D.C.Cir.1984) (Wald, J.)

. If, as suggested here, the manufacturer’s obligation to recall and repair a nonconforming vehicle attaches at the time the agency makes a determination of nonconformity and gives notice, some cars may be beyond their useful lives by the time they are repaired. If a particular vehicle’s status at the time of the determination were contested, however, its age could be easily ascertained by reference to the bill of sale, and its mileage could be rebuttably presumed to have increased uniformly throughout its period of ownership. Such a presumption would need to be resorted to only rarely, and would be reasonable under the circumstances.
