concurring in the judgment:
The Center for Auto Safety (Center) petitions to review the withdrawal by the National Highway Traffic Safety Administration (Highway Administration) of an advance notice of proposed rulemaking which sought public comment on possible improvements in the fuel economy of automobiles and light trucks in the 1985-1995 period. The advance notice stated that its issuance did not necessarily indicate that fuel economy standards would be established and that its purpose was to gather pertinent information to determine whether standards should be set and, if so, at what level. Within three months of its issuance, the Highway Administration withdrew the advance notice because it believed that market forces made it unnecessary to initiate rulemaking on post-1984 fuel economy standards and, therefore, that the public comments which would be received could not be put to significant use. The Center petitioned the Highway Administration to reconsider its withdrawal of the advance notice, contending that withdrawal was not supported by the reasons given, was unreasonable in view of the requirements of the Energy Policy and Conservation Act, Pub.L. No. 94H63, 89 Stat. 871 (1975), and was not in the public interest. I conclude that the agency’s decision to withdraw the advance notice constituted “agency action ... committed to agency discretion by law,” excepted from judicial review by the Administrative Procedure Act, 5 U.S.C. § 701(a)(2) (1976). I therefore agree that the petition for review must be dismissed.

In response to dislocations in the nation’s economy caused by the OPEC oil embargo of 1973-1974, Congress enacted the Energy Policy and Conservation Act, Pub.L. No. 94-163, 89 Stat. 871 (1975) (Conservation Act), for the purposes “of increasing domestic supply, conserving and managing energy demand, and establishing standby programs for minimizing this nation’s vulnerability to major interruptions in the supply of petroleum imports.” H.R.Rep. No. 94-340, 94th Cong., 1st Sess. 1 (1975), U.S.Code Cong. & Admin.News 1975,1762,1763. Recognizing that the automobile represented the largest single user of petroleum in the United States,1 the Conservation Act created a program of mandatory fuel economy standards for automobiles and light trucks.2 Energy *850Policy and Conservation Act, Pub.L. No. 94-163, § 301, 89 Stat. 871, 901 (1975). Although the Act established, inter alia, mandatory fuel economy standards for passenger automobiles for model year 1985 and beyond, 15 U.S.C. § 2002(a)(1) (1976),3 it also authorized the Highway Administration,4 subject to congressional approval, to amend such standards to reflect the “maximum feasible average fuel economy level” for those model years. Id. § 2002(a)(4).5
On January 19, 1981, the Highway Administration issued an advance notice of *851proposed rulemaking (January Notice) which sought “public comment on the improvements that can be made in passenger automobile and light truck fuel economy in the 1985-1995 period.”6 In April 1981, the President announced a “program to address directly the immediate problems of depressed sales, record losses, and severe unemployment” plaguing the automobile industry in the United States. Office of the Press Secretary, Actions to Help the U.S. Auto Industry 1 (Apr. 6, 1981). As part of this program, the Highway Administration indicated that the January Notice would be withdrawn because the agency believed “the initiation of rulemaking on post-1985 fuel economy standards to be unnecessary.” Id. at A-35. See Notice of Intent, 46 Fed. Reg. 21,203, 21,204 (1981). The agency subsequently withdrew the January Notice, finding that strong consumer demand for fuel efficient vehicles had resulted in a firm commitment on the part of automobile manufacturers to improve the fuel economy of their products. Accordingly, it concluded that
given the present situation, it is unlikely that the agency will need to commence rulemaking in the foreseeable future. Therefore, any information submitted in response to the [January Notice] would serve no immediate rulemaking purpose and would not be sufficiently current for use in the longer run. Withdrawal of the notice will save the industry and public from having to make the effort to prepare information that cannot be put to significant use.7
The Center promptly petitioned the Highway Administration to reconsider its decision withdrawing the January Notice. The Center asserted that withdrawal of the January Notice was “not supported by the reasons cited, [was] unreasonable in light of the expressed purposes and commands of the [Conservation] Act, and [was] not in the public interest.”8 Disputing each of the Center’s contentions, the Highway Administration denied the Center’s petition for reconsideration.9 The Center then filed its petition for review with this Court.
The Highway Administration moved to dismiss the Center’s petition for review, *852contending that the Court did not have jurisdiction po review its withdrawal of the January Notice and, alternatively, that the matter was' not ripe for judicial review. Part II of our Per Curiam opinion, in which I join, holds that this Court has jurisdiction to review the Highway Administration’s decision to withdraw the January Notice. Nevertheless, I conclude that the Conservation Act vests the Highway Administration with broad discretion to determine whether to amend the post-1984 fuel economy standards, and that the agency’s exercise of that discretion in this case is not subject to judicial review.10 Accordingly, I join in dismissing the Center’s petition for review.

A.
Review of the Highway Administration’s decision is governed by the Administrative Procedure Act,11 which provides that an agency action is judicially reviewable, except to the extent that the “agency action is *853committed to agency discretion by law.” 5 U.S.C. § 701(a)(2) (1976).12 “This section creates a strong presumption of reviewability that can be rebutted only by a clear showing that judicial review would be inappropriate.” Natural Resources Defense Council, Inc. v. SEC, 196 U.S.App.D.C. 124, 136, 606 F.2d 1031, 1043 (1979). In determining whether judicial review of an agency action is appropriate, it is necessary to consider three factors:
the need for judicial supervision to safeguard the interests of the plaintiffs; the impact of review on the effectiveness of the agency in carrying out its congres-sionally assigned role; and the appropriateness of the issues raised for judicial review.
Id. at 137, 606 F.2d at 1044.
This Court has previously considered the reviewability of an agency’s exercise of discretion in the context of the agency’s refusal to adopt a proposed rule. In Natural Resources Defense Council, Inc. v. SEC, supra, the Court considered whether an SEC decision not to promulgate a proposed environmental and equal employment disclosure rule after extensive rulemaking proceedings was properly reviewable. The Court concluded that in the context of an agency’s decision not to adopt a rule the interests of the plaintiffs
rarely present unusual or compelling circumstances calling for judicial review. In the present case, for example, the SEC has not invaded any of [their] substantive statutory or constitutional rights, nor singled them out for special and seemingly unfair treatment, nor even, indeed, taken any action to alter the status quo ante.
Id. at 138, 606 F.2d at 1045 (footnote omitted). Furthermore, the Court noted that judicial review necessarily interferes with an agency’s effective performance of its statutory mission:
Requiring an agency to defend in court its decision not to adopt proposed rules will divert scarce institutional resources into an area that the agency in its expert judgment has already determined is not even worth the effort already expended.... [T]he very prospect of litigation may cause the agency to give a proposal more elaborate consideration than it might actually merit.
Id. (emphasis added).
Finally, the Court recognized that the strongest argument against reviewability was that the issues posed will often be inappropriate for judicial review.
An agency’s discretionary decision not to regulate a given activity is inevitably based, in large measure, on factors not inherently susceptable to judicial resolution — e.g., internal management considerations as to budget and personnel; evaluations of its own competence; weighing of competing policies within a broad statutory framework.... [E]ven if an agency considers a particular problem worthy of regulation, it may determine for reasons lying within its special expertise that the time for action has not yet arrived.... The circumstances in the regulated industry may be evolving in a way that could vitiate the need for regulation. ...
Id. at 139, 606 F.2d at 1046 (emphasis added). The Court concluded that when an agency does not adopt a rule, “the record and reasons statement will be of little use to a reviewing court unless they are narrowly focused on the particular rule advocated by plaintiff or petitioner.” Id. (emphasis added).
Nevertheless, the NRDC Court found the SEC’s decision not to adopt the rule at issue properly reviewable under the circumstances presented. The Court did not hold that agency decisions not to adopt rules were “reviewable per se ” because “the relevant factors incline against reviewability....” Id. at 140, 606 F.2d at 1047. Rather, the Court concluded that
*854discretionary decisions not to adopt rules are reviewable where, as here, the agency has in fact held a rulemaking proceeding and compiled a record narrowly focused on the particular rules suggested but not adopted.
Id. (footnote omitted) (emphasis added).
Subsequently, in WWHT, Inc. v. FCC, 211 U.S.App.D.C. 218, 656 F.2d 807 (1981), this Court held that an FCC order denying a rulemaking petition was properly reviewable under the principles enunciated in NRDC. The rulemaking petition suggested a proposed rule and the FCC received limited comments on that rule. Id. at 222-23, 656 F.2d at 811-12. Conceding that “the case for reviewability of the order . .. [was] even less compelling than that in NRDC,” id. at 228, 656 F.2d at 817, the Court held that the order was reviewable because of the strong presumption in favor of judicial review. Id. at 226-27, 656 F.2d at 815-16.13
Thus in NRDC we concluded that the SEC’s decision not to adopt a rule was a proper subject for judicial review because the agency had compiled an extensive record focused on that rule. Similarly, in WWHT we concluded that the FCC’s denial of a rulemaking petition was a proper subject for judicial review because the agency’s decision was focused on the particular rule suggested by the petition.14 In this case, however, the Highway Administration’s decision was not focused on any particular fuel economy standard. Applying the principles established in NRDC and WWHT, I conclude that the agency’s decision to withdraw the January Notice was an exercise of its discretion not subject to judicial review.
B.
Preliminarily, it is clear that the Conservation Act leaves the decision whether to amend the post-1984 fuel economy standards to the discretion of the Highway Administration. The Act provides that the Highway Administration may amend those standards, but provides no guidance as to how the agency is to determine whether such amendments are appropriate.15 Furthermore, nothing in the legislative history of the Conservation Act limits the discretion of the Highway Administration in deciding if and when to amend the post-1984 fuel economy standards.16 Thus the Highway Administration has broad discretion to amend the post-1984 fuel economy stan*855dards, subject only to congressional review. 15 U.S.C. § 2002(a)(4) (1976).17
Consideration of the Highway Administration’s decision at issue in this case in light of the three factors relevant to the determination of reviewability set forth in NRDC,18 indicates that its decision is not appropriate for judicial review. At the outset I note that the Center simply has not demonstrated any compelling need for judicial intervention to safeguard its interests. The Highway Administration’s decision withdrawing the January Notice did not alter the congressional mandated post-1984 fuel economy standards. The only opportunity arguably foreclosed by the agency’s decision was an opportunity for the Center to comment on potential fuel economy improvements in the 1985-1995 period.19 Judicial intervention is not necessary to vindicate this interest for if, in fact, the Center has any meaningful contribution to make on the subject of automotive fuel economy, it may submit such information to the Highway Administration in the context of a petition for rulemaking seeking amendment of the post-1984 fuel economy standards.
Furthermore, judicial review of the Highway Administration’s decision would likely impair the effectiveness of the agency. The January Notice sought public comment on possible improvement in automobile and light truck fuel economy in the 1985-1995 period. Since the Highway Administration has broad discretion to determine if and when to amend the post-1984 fuel economy standards, it necessarily must have even greater discretion to decide if and when it will seek public input to assist in its determination whether to consider such amendments. Judicial review of agency decisions regarding whether to seek public comment on their activities would magnify the importance of such decisions and would have the undesirable effect of making agencies reluctant to seek public participation unless required to do so by statute or regulation. Such a result could only hamper the ability of agencies to perform their statutory duties.
Finally, the Highway Administration’s decision to withdraw the January Notice is not well-suited for judicial review. Whereas in NRDC the agency developed an extensive record on the basis of rulemaking proceedings focused on a particular rule, and in WWHT the agency decision focused on a specific proposed rule, in this case the Highway Administration proposed no amendments to the post-1984 fuel economy standards in its January Notice. Nor did the Center propose any specific amendments to the post-1984 fuel economy standards in its petition for reconsideration of the Highway Administration’s decision. As a result, the record of the Highway Administration’s decision consists primarily of conclusory statements by the agency explaining why withdrawal of the January Notice was appropriate, and statements of a similar nature by the Center explaining why withdrawal was inappropriate.20 Since the Highway Administration’s decision did not focus on the merits of a particular amendment to the fuel economy . standards, “judicial review [would] have an undesirably abstract and hypothetical quality.” Natural Resources Defense Council, Inc. v. SEC, supra, 196 U.S.App.D.C. at 140, 606 F.2d at 1047. This Court found the case for reviewability less compelling in WWHT than in NRDC because the agency had not instituted rule-making proceedings on the proposed rule, WWHT, Inc. v. FCC, supra, 211 U.S.App.D.C. at 228, 656 F.2d at 817. I find it even less so in this case where the record available for review is not focused on any proposed agency action.
C.
The case for holding the Highway Administration’s decision to withdraw the Jan*856uary Notice reviewable is far weaker than the case for finding the agency’s decision reviewable in either NBDC or WWHT. While the Center has failed to identify any significant interest which would be protected by our review of the agency’s decision, it is clear that such review would discourage the Highway Administration from seeking public input into its decisionmaking process, thereby impairing its effectiveness. Furthermore, the record in this case is poorly suited for judicial review because it is not focused on any particular amendment to the fuel economy standards.
Our previous decisions recognize that the Administrative Procedure Act excepts certain actions committed to agency discretion from judicial review.21 Cognizant of the strong presumption in favor of judicial review, I nevertheless hold that the Highway Administration’s withdrawal of the January Notice, which sought public comment on possible fuel economy improvements in the 1985-1995 period, is such an action and is not subject to judicial review.
Accordingly, I join in dismissing the Center’s petition for review.
. S.Rep. No. 94-179, 94th Cong., 1st Sess. 2 (1975). Congress found that in 1972
motor vehicles accounted for almost 20 percent of all energy consumed in the United States, and about 40 percent of all petroleum products consumed in the United States.
H.R.Rep. No. 94-340, supra, at 86, U.S.Code Cong. & Admin.News 1975, at 1848.
. Legislation providing for mandatory fuel economy standards for automobiles was first introduced in the Senate by Senator Hollings in 1973. S. 1903, 93d Cong., 1st Sess., 119 Cong. Rec. 17,230-33 (1973). An amended version of S. 1903 was incorporated into the Senate’s omnibus energy conservation bill, the National Fu*850els and Energy Conservation Act of 1973, S. 2176, 93d Cong., 1st Sess. (1973). S.Rep. No. 93-526, 93d Cong., 1st Sess. 5-6 (1973). The legislation established a goal of “improving the industrywide fuel economy for new automobiles by at least 50% in 1984 in comparison to the 1974 model year.” Id. at 51. The Secretary of Transportation was directed to establish “a single minimum fuel economy standard for the 1978 model year” and was permitted to establish such additional minimum fuel economy standards as necessary to achieve the con-gressionally mandated goal. Id. Although S. 2176 passed the Senate, 119 Cong.Rec. 40,446 (1973), it died in the House. S.Rep. No. 94-179, 94th Cong., 1st Sess. 18 (1975).
In the 94th Congress, a number of bills dealing with automobile fuel economy were introduced in the Senate. After hearings, the substance of these bills was consolidated into a single bill entitled the Automobile Fuel Economy and Research and Development Act of 1975, S. 1883, 94th Cong., 1st Sess. (1975). S.Rep. No. 94-179, 94th Cong., 1st Sess. 18 (1975). This legislation required the Secretary of Transportation to “establish standards for minimum average fuel economy for new automobiles and light duty trucks manufactured in model years 1977 through 1985.” Id. at 20. The fuel economy standards were to be set at “maximum feasible levels” and were
to result in an industrywide average fuel economy level increase of 50 percent [to 21 miles per gallon] by model year 1980 over model year 1974 models [and] ... in an in-dustrywide average fuel economy level which represents at least a 100-percent improvement (to 28 miles per gallon) by model year 1985 over the 1974 average.
Id. S. 1883 passed the Senate. 121 Cong.Rec. 22,879 (1975).
Similarly, automobile fuel economy legislation was considered by the House in the 94th Congress, first as a floor amendment to H.R. 6860, 94th Cong., 1st Sess. (1975) — which sought to encourage conservation of energy through tax incentives and disincentives — offered by Representative Sharp, 121 Cong.Rec. 18,695 (1975), and later as part of a comprehensive energy conservation bill, the Energy Conservation and Oil Policy Act of 1975, H.R. 7014, 94th Cong., 1st Sess. (1975). H.R.Rep. No. 94-340, supra, at 87-88. This legislation established average fuel economy standards for automobiles in several model years, including a standard of 20.5 miles per gallon for model year 1980 and a standard of 28.0 miles per gallon for model year 1985. The Secretary of Transportation was required to establish fuel economy standards for model years 1981-1984, and was authorized to amend the 1985 standard, subject to congressional disapproval. Id. at 88-89. H.R. 7014 passed in the form of an amendment to S. 622, 94th Cong., 1st Sess. (1975), a bill passed by the Senate, 121 Cong. Rec. 9868 (1975), granting standby rationing and other authority to the President in the event of an embargo or other curtailment of petroleum supplies. 121 Cong.Rec. 29,852-53 (1975).
The Senate subsequently amended the House amendment to S. 622 to include, inter alia, the automobile fuel economy provisions of S. 1883. 121 Cong.Rec. 30,594, 30,617 (1975). The conference substitute for S. 622 included a compromise version of the fuel economy legislation which closely resembled that adopted by the House in H.R. 7014. See S.Rep. No. 94-516, 94th Cong., 1st Sess. 149-60 (1975) (comparison of fuel economy provisions of H.R. 7014, S. 1883, and conference substitute). The conference substitute, however, extended the 1985 model year fuel economy standard to subsequent model years. Id. at 154. The conference substitute was adopted as the Energy Policy and Conservation Act. 121 Cong.Rec. 40,739, 41,196 (1975).
. The Conservation Act provides that the average fuel economy for passenger automobiles manufactured after model year 1984 shall not be less than 27.5 miles per gallon. 15 U.S.C. § 2002(a)(1) (1976).
. The Conservation Act vests the Secretary of Transportation with the authority to enforce the mandatory fuel economy standards for automobiles. See, e.g., 15 U.S.C. § 2008 (1976 & Supp. V 1981). The Secretary has delegated these responsibilities to the Highway Administration. 49 C.F.R. § 501.2(f) (1982).
. 15 U.S.C. § 2002(a)(4) (1976) provides:
The Secretary may, by rule, amend the average fuel economy standard specified in paragraph (1) for model year 1985, or for any subsequent model year, to a level which he determines is the maximum feasible average fuel economy level for such model year, except that any amendment which has the effect of increasing an average fuel economy standard to a level in excess of 27.5 miles per gallon, or of decreasing any such standard to a level below 26.0 miles per gallon, shall be submitted to the Congress ... and shall not take effect if either House of the Congress disapproves such amendment....
. Advance Notice of Proposed Rulemaking, 46 Fed.Reg. 8056, 8056 (1981). The January Notice did not propose any new fuel economy standards:
The issuance of this notice does not necessarily indicate that standards will be established, but rather is intended as an information gathering process to determine whether standards should be set and, if so, at what level....
Id. at 8056-57 (emphasis added).
. Withdrawal of Advance Notice of Proposed Rulemaking, 46 Fed.Reg. 22,243, 22,243 (1981).
. Letter from the Center for Auto Safety to Raymond Peck, Administrator, National Highway Traffic Safety Administration 1 (May 16, 1981). The Center argued that it was inappropriate for the Highway Administration to rely on consumer demand to spur voluntary efforts by automobile manufacturers to improve the fuel economy of their products. The Center asserted that “[n]othing in the public record of the fuel economy program suggests that in the absence of performance standards, the industry’s efforts to produce efficient vehicles will be any more energetic, effective, or competitive with foreign makers’ after 1985, than they were in the 1970’s” when “[r]eliance upon market pressures and voluntary industry efforts [were] explicitly and vehemently rejected by Congress in establishing the fuel economy program, because of the industry’s deplorable record..., ” Id. at 2.
The Center also contended that the Highway Administration had not demonstrated that reliance on market forces for fuel economy improvements would result in achieving the congressional goal “that the ‘maximum feasible’ average fuel economy be attained” in the post-1984 period. Id. at 3. Accordingly, the Center concluded that by withdrawing the January Notice the agency had failed to meet its obligation under the Conservation Act of “securing the greatest fuel economy achievements possible.” Id.
. Letter from Michael M. Finkelstein, Associate Administrator for Rulemaking, National Highway Traffic Safety Administration, to the Center for Automobile Safety 1 (Sept. 25, 1981). See Denial of Petition, 46 Fed.Reg. 48,383 (1981). The Highway Administration reiterated that market forces were stimulating manufacturers to develop fuel efficient vehicles and that “the need for rulemaking to further improve fuel economy in the foreseeable future-appears unlikely.” Letter from Michael Finkel-stein, Associate Administrator for Rulemaking, *852National Highway Traffic Safety Administration, to the Center for Automobile Safety 2 (Sept. 25, 1981). The agency indicated that United States manufacturers had exceeded the fuel economy standards for model years 1980 and 1981, and cited evidence that the manufacturers planned to exceed the 1985 standards. Id. at 2-3.
The Highway Administration also disputed the Center’s allegation that withdrawal of the January Notice was contrary to the Conservation Act and the public interest. The agency noted that its “[c]ontinued monitoring of the demands of the market and the efforts of manufacturers to improve fuel economy will enable [it] to determine the timing and extent of any further actions required under the statute.” Id. at 3. Noting that the Conservation Act granted it discretion to review and amend the post-1984 fuel economy standards, the Highway Administration stated “that the industry’s ongoing program of new investment to make its products more competitive and modernize its plants will result in meeting consumer demands and fulfilling the Nation’s energy conservation goals in this sector.” Id. The agency concluded that “[a]s long as the demands of the marketplace are being met and these demands fulfill the Nation’s energy conservation goals, the public interest is being served.” Id. at 4.
. I find it necessary to decide whether the Highway Administration’s decision to withdraw the January Notice is subject to judicial review because, in my view, the decision is ripe for review. The Per Curiam opinion concedes that
a decision not to amend the 27.5 mpg standard for 1985 model year vehicles [would be] a final agency action currently ripe for review.
Per Curiam Op., supra, at '847. Nevertheless, it concludes that the Highway Administration’s decision is not yet ripe for review because the fuel economy standard for 1985 is not being challenged in this case. Id. at 846-849. I do not agree.
The agency action challenged in this case is the withdrawal of a notice entitled “Passenger Automobile and Light Truck Average Fuel Economy Standards; Model Year 1985 and Beyond” which sought public comments “on the improvements that can be made in ... fuel economy in the 1985-1995 period.” Advance Notice of Proposed Rulemaking, 46 Fed.Reg. 8056, 8056 (1981) (emphasis added). The Center’s petition for reconsideration requested the Highway Administration to “complete the rulemaking prior to making so final a decision whether to issue standards for 1985 and later model years” and “to continue the rulemaking concerning fuel economy improvements in 1985 and later model years.” Letter from the Center for Auto Safety to Raymond Peck, Administrator, National Highway Traffic Safety Administration 1, 3 (May 16, 1981) (emphasis added). That these two critical documents in the record clearly refer to the fuel economy standard for the 1985 model year demonstrates that the 1985 standard is at issue in this case. Therefore, since I agree that the time limits imposed by the Conservation Act require that an amendment to the 1985 standard be in place by early 1983 and that that time has passed, Per Curiam Op., supra, at 847-848, I conclude that the Highway Administration’s decision to withdraw the January Notice is ripe for review.
. 15 U.S.C. § 2004(a) (1976) provides;
Any person who may be adversely affected by any rule prescribed under section 2001, 2002, 2003, or 2006 of this title may, at any time prior to 60 days after such rule is prescribed ... file a petition in the United States Court of Appeals for the District of Columbia ... for judicial review of such rule.... [The clerk of that court] shall thereupon cause to be filed in such court the written submissions and other materials in the proceeding upon which such rule was based. Upon filing of such petition, the court shall have jurisdiction to review the rule in accordance with [the judicial review provisions of the Administrative Procedure Act, 5 U.S.C. § 701 ei seq. (1976) ]....
. Judicial review is also prohibited to the extent that “statutes preclude judicial review. ...” 5 U.S.C. § 701(a)(1) (1976). There has been no suggestion by the parties that the Conservation Act precludes review of the Highway Administration’s decision to withdraw the January Notice.
. The Court tempered its decision by stating that
the decision to institute rulemaking is one that is largely committed to the discretion of the agency, and that the scope of review of such a determination must, of necessity, be very narrow.

. However, the Conservation Act requires that any fuel economy standard be set at the “maximum feasible average fuel economy level” if the Highway Administration exercises its discretion to amend that standard. 15 U.S.C. § 2002(a)(4) (1976). The Act further provides that
in determining maximum feasible average fuel economy, the Secretary shall consider—
(1) technological feasibility;
(2) economic practicability;
(3) the effect of other Federal motor vehicle standards on fuel economy; and
(4) the need of the Nation to conserve energy.
Id. § 2002(e).
My colleagues “fail to realize” the distinction between the discretion afforded by the Act to the Highway Administration in deciding whether to amend the fuel economy standards and the constraints imposed by the Act on the agency in amending the fuel economy standards if it exercises its discretion to do so. Per Curiam Op. at 849 n. *. The mere fact that the Conservation Act does not grant the Highway Administration unfettered discretion to amend the congressionally established post-1984 fuel economy standard does not limit, as my colleagues imply, the broad discretion to determine whether to amend that standard clearly granted to the agency by the Act.
. In discussing section 2002(a)(4), the Conference Report on the Conservation Act stated:
The [Highway Administration] is given authority to adjust the “1985 and thereafter” standard ... to a level which he determines is the maximum feasible average fuel economy level for any such model year.
