PROF. DRIVERS COUNCIL v. BUR. OF MOTOR CAR.

Opinion for the Court filed by Circuit Judge MacKINNON.

MacKINNON, Circuit Judge.

After six years of study, investigation, and hearings which the Secretary of Transportation initiated, in part, in response to a petition by the Professional Drivers Council, the Secretary decided not to amend the regulations governing the hours-of-service for over-the-road truck drivers. The Drivers petition for review of this refusal. We affirm the decision of the Secretary.

I. BACKGROUND

On September 3, 1981, the Bureau of Motor Carrier Safety (Bureau) terminated rulemaking proceedings designed to amend the regulations which govern the hours-of-service for drivers of commercial motor vehicles. The agency decided not to amend the existing regulations. On October 1, 1981, the Professional Drivers Council (Drivers) petitioned the Secretary of Transportation (Secretary)1 to reconsider the decision to terminate rulemaking and requested that rulemaking, addressing three specific "loopholes" in the existing scheme, be reinitiated. On November 20, 1981, the Secretary denied the Drivers' petition. The Drivers petitioned for review in this court seeking to have the Secretary's actions reversed as being "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law." The Drivers assert that the existing hours-of-service regulations are inadequate and that the agency has steadfastly refused to close "loopholes" in the regulations.2

The first hours-of-service regulations, enacted by the Interstate Commerce Commission3 pursuant to the Motor Carrier Act of 1935, 49 Stat. 543,4 became effective on October 1, 1938 and governed only common and contract passenger carriers. 6 M.C.C. 557 (1938). On March 1, 1939, following extensive hearings, the Commission extended its hours-of-service regulations, with some modifications, to all common and contract property carriers. 11 M.C.C. 203 (1939). With certain modifications, these rules were eventually extended to cover private carriers as well. 23 M.C.C. 1 (1940).

From the beginning, regulating a driver's hours-of-service has not been an exact science and the agency has relied heavily upon its expertise in developing a regulatory scheme. As the Commission acknowledged in 1938:

6 M.C.C. at 561. When reconsidering the applicability of the new rules to common and contract property carriers, the Commission stated:

11 M.C.C. at 210. Notwithstanding this lack of factual foundation, the Commission, relying upon public comment and its own expertise, promulgated hours-of-service rules.

In 1959, the Commission initiated rulemaking proceedings which were intended to amend Part 195 of the Motor Carrier Safety Regulations which governs the hours-of-service for drivers.5 Because of the substantial nature of the revisions proposed, extensive public hearings were held in three cities and, based upon this record, a hearing examiner submitted his recommendations for amending the regulations to the Commission.6 After reviewing the examiner's recommendations, the Commission adopted the regulations as revised. The new regulations became effective July 16, 1962.7 These regulations have remained essentially unchanged and are the regulations at issue in this case.

Seeking to insure the continuing vitality of the regulations, the Bureau of Motor Carrier Safety initiated research into the area of driver fatigue in the early 1970s. In 1972, the Bureau published the results of a year-long study of driver fatigue, A Study of the Relationships Among Fatigue, Hours of Service, and Safety of Operations of Truck and Bus Drivers ("Phase I Fatigue Study"). In response to this study the Drivers filed a rulemaking petition requesting that the agency commence proceedings to amend the existing hours-of-service rules. The agency declined to commence rulemaking, choosing to await the results of additional studies. In November, 1973, the Drivers again petitioned the agency to initiate rulemaking. The agency again responded that more information was needed and refused to commence rulemaking. The Drivers filed suit based upon the agency's denial. This action was dismissed without prejudice to the filing of a subsequent action if, within eighteen months the agency did not publish a Notice of Proposed Rulemaking. PROD, Inc. v. Brinegar, Civ. No. 2098-73 (D.D.C. Sept. 12, 1974). An Advance Notice of Proposed Rulemaking was published in February, 1976.8 The stated purpose of the notice was to solicit views regarding revision of the hours-of-service rules. The Advance Notice stated that although the Agency did "not have conclusive information . . . to support rule changes, [it was] in the process of conducting the final stages of . . . research efforts to scientifically quantify the relationships between hours of service of interstate truck and bus drivers and driver fatigue."9

Based upon the response to the 1976 Advance Notice, the agency concluded that the hours-of-service regulations needed "extensive revision" and the agency drafted "a preliminary set of proposals" for amendment of the existing rules. [Plans I, II, and III]. The agency revealed these proposals in an Advance Notice of Proposed Rulemaking, and announced that public hearings on the plans would be held in seven major cities.10 A majority of the public comments received during these hearings were in opposition to the proposals.11

In compliance with Executive Orders,12 the agency conducted a Regulatory Impact Analysis (RIA) of each of the proposed amendments.13 The RIA results indicated that "aggregate costs are far in excess of any foreseeable societal benefits emanating from possible changes to the existing regulations."14

On September 3, 1981, the agency terminated the rulemaking without amending the existing rules. The notice terminating the proceedings stated:

46 Fed.Reg. 44198 (1981). Following this announcement, the Drivers petitioned the Secretary to reconsider the decision and to reinstitute rulemaking specifically designed to remedy three deficiencies which the Drivers identified in the existing rules. On November 20, 1981, the Drivers' petition was denied. This petition for review followed.

II. ANALYSIS

A. Standard of Review

As this case involves informal rulemaking, the proper standard for judicial review is contained in 5 U.S.C. § 706(2)(A)(D) (1976). This standard of review requires a court to set aside agency action which is "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law." Id. § 706(2)(A). Camp v. Pitts, 411 U.S. 138, 140-42, 93 S.Ct. 1241, 1243-44, 36 L.Ed.2d 106 (1973); Action for Children's Television v. FCC, 564 F.2d 458, 478-79 (D.C.Cir.1977). Descriptions of the "arbitrary and capricious" standard emphasize that while such review is "searching and careful," it must also be circumspect. The reviewing court must be cautious not to substitute its judgment for that of the agency. The court's task is to discern whether the relevant factors were considered and whether the ultimate decision reflects reasoned decision-making.

We have previously reviewed an agency decision not to amend existing regulations. Natural Resources Defense Council v. SEC, 606 F.2d 1031 (1979); Action for Children's Television v. FCC, supra. The threshold consideration in exercising judicial review under these circumstances is to determine whether the action is in fact amenable to review. Cognizant of the factors considered in prior opinions which counsel against review of these discretionary agency decisions, we determine that the decisions challenged herein are reviewable.15

Our review is, however, limited. The circumscribed scope of this review is dictated by both the nature of the administrative proceeding (informal rulemaking) and by the nature of the ultimate decision (not to promulgate rules). The record in an informal rulemaking proceeding is "a less than fertile ground for judicial review" and has been described as a "sump in which the parties have deposited a sundry mass of materials." National Resources Defense Council, supra, 606 F.2d at 1052. Thus, the practical realities constrain our review. Furthermore, rulemaking is an inherently policy-oriented process and the agency must be accorded considerable deference in evaluating information presented and reaching decisions based upon its expertise. Our review is also circumscribed by the fact that the agency decided not to promulgate new rules in an area already heavily regulated. This is not a situation where the agency has shirked its statutory duty by refusing to regulate. The agency has regulated the field. In this instance, the agency's statutory authority to regulate is permissive. The statute provides that the agency "may establish reasonable requirements." The permissive nature of the statute implies broad agency discretion in selecting the appropriate manner of regulation. No regulatory scheme is perfect, and the agency's decision to refrain from amending the elaborate, established regulatory scheme cannot be disturbed absent a strong showing that such action was unreasonable. This is not to say that this court's review of the agency's action will be merely perfunctory. As Judge McGowan defined this illusive standard of review:

Natural Resources Defense Council, supra, 606 F.2d at 1053 (citations and footnotes omitted).16

B. Termination of Rulemaking Proceedings

The agency declined to adopt any of the proposals contained in the 1978 Advance Notice and closed its rulemaking proceedings. In support of this decision, the agency cited the "absence of evidence of a direct relationship between hours of service and a significant reduction in accidents" and "the economic impact of the proposed options on motor carrier operations and the Nation's distribution system."17 The agency also noted the substantial opposition to amending the regulations as reflected in the comments, both written and orally presented at public hearings.18 The agency clearly articulated the factual and policy bases for its decision. There can be no question but that the agency's decision

Action for Children's Television, supra, 564 F.2d at 479 (footnotes omitted).

Reviewing the studies that it had commissioned, the agency concluded that no consistent relationship between driver fatigue, hours of driving, and motor vehicle accidents could be discerned which would require changing the existing regulations. The agency was unable to conclude that safety would be enhanced by adopting any of the three proposals.

Petitioners assert that it was improper for the agency to base its decision upon this absence of direct evidence correlating driver fatigue, hours of service, and road accidents. Petitioners contend that the agency has "erected improper evidentiary burdens" because sufficient data correlating fatigue and accidents will never be available. The Drivers contend that in spite of the fact that reliable data is unavailable, the agency has a "congressional mandate" to promote safety and, therefore, the agency is required to amend its regulations. This position is untenable in light of the independence afforded the agency by its enabling statute. The statute is permissive in its language; directing that the agency "may establish reasonable requirements." 49 U.S.C. § 304(a)(1)—(2) (emphasis added). In fact, the agency has established such requirements. In deciding to terminate rulemaking proceedings, the Secretary concluded that insufficient evidence existed to warrant changing the existing requirements. Such a decision is based upon agency expertise and is accorded significant deference by this court.19 With only inconclusive data available, the agency was relying upon its expertise to determine the best course for regulation. The agency was clearly acting within its discretion in determining not to amend the existing regulations.

Petitioners also allege that the agency impermissibly allowed economic considerations to "dictate" its decision. Initially it should be noted that petitioners overstate their case. In reaching its decision the agency relied upon factors in addition to the economic ramifications of amending the regulations. Furthermore, the Drivers fail to reveal why the agency's consideration of economic impact was impermissible.20 Executive Orders21 specifically require an agency to evaluate the economic impact of its regulations. It was, therefore, permissible for the agency to consider costs and benefits in deciding not to amend its regulations.

The Bureau's decision to terminate rulemaking proceedings without amending its existing rules, after ten years of study and consideration of the issues, was a rational decision. The agency relied upon relevant, permissible factors, including its expertise, and its conclusions are supported by facts in the record. Therefore, the agency's decision to terminate rulemaking without amending its hours-of-service regulations must be upheld.

C. Denial of Petition to Institute New Rulemaking Proceedings

Petitioners also challenge the Secretary's denial of their petition to recommence rulemaking proceedings confined to the three "loopholes" in the regulations.22 An agency possesses a "generous measure of discretion respecting the launching of rulemaking proceedings." Geller v. FCC, 610 F.2d 973, 979 (D.C.Cir.1979). "It is only in the rarest and most compelling of circumstances that this court has acted to overturn an agency judgment not to institute rulemaking." WWHT, Inc. v. FCC, 656 F.2d 807, 818 (D.C.Cir.1981).23 Review of an agency's denial of a rulemaking petition is under the "arbitrary and capricious" standard and for purposes of review the court will look to the "petition for rulemaking, comments pro and con where deemed appropriate, and the agency's explanation of its decision to reject the petition." Id.

In this instance the Secretary clearly stated his reasons for denying the petition. After fully reviewing the reasons for terminating the hours-of-service proceeding, the Secretary stated:

Jt. App. at 51.

The Secretary's refusal to recommence rulemaking proceedings came only approximately two and one-half months after the termination of six years of rulemaking proceedings addressing this very topic. The information acquired by the agency during these proceedings supports its decision not to initiate new rulemaking proceedings. The agency's assertion that it was unlikely that new information would be revealed in rulemaking proceedings is a reasonable conclusion.

The essence of petitioners' challenge is that the agency did not fairly assess the particular concerns cited by the Drivers, but rather denied the petition based on the conclusions reached vis-à-vis other proposed rules. It is well established that "[a]dministrative rulemaking does not ordinarily comprehend any rights in private parties to compel an agency to institute such proceedings or promulgate rules." Rhode Island Television Corp. v. FCC, 320 F.2d 762, 766 (D.C.Cir.1963).24 The Drivers had no right to compel the agency to hold rulemaking proceedings addressing its specific recommendations for amending the existing rules. Nevertheless, in its response, the agency attempted to delineate the overlap between the changes sought by the Drivers and the amendments which had already been considered and rejected during the extensive rulemaking. It was the considered judgment of the agency that even limited amendment of the existing rules was not warranted given the inconclusive test findings and the generally negative public reaction to the suggested amendment of the rules. The agency reasonably exercised its discretion to deny the Drivers' petition to institute new rulemaking proceedings.

III. CONCLUSION

This review focuses upon only two actions by the agency: (1) the termination of rulemaking proceedings without amending the rules; and (2) the denial of the Drivers' petition for recommencing rulemaking. In both instances, we find that the agency adequately considered the relevant factors and reached a reasoned decision. These agency actions are not "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law." The judgment of the Secretary is entitled to considerable deference and for the reasons set forth above we affirm his decision in both instances.

Judgment accordingly.
