Impact on Small Entities D. Unfunded Mandates Act I. Introduction and Background Section 202(a) of the Clean Air Act authorizes EPA to promulgate emission standards for motor vehicles, including motorcycles. Section 202 (a)(3)(E) of the Act requires that EPA, when setting emission standards for motorcycles, ``consider the need to achieve equivalency of emission reductions between motorcycles and other motor vehicles to the maximum extent practicable.'' EPA has promulgated emission standards and accompanying regulations controlling emissions from new motorcycles. See 42 FR 1122 (January 5, 1977). These regulations included the definition of ``motorcycle.'' EPA originally proposed a definition of ``motorcycle'' which would have included any 3-wheeled vehicle ``which is not a passenger car or passenger car derivative'' regardless of weight. 1 Adverse public comment was received stating that some small 3-wheeled vehicles share characteristics of a passenger car as well as a motorcycle and therefore much confusion would arise as to whether that vehicle should be regulated as a passenger car or a motorcycle. EPA agreed with these comments, and revised its definition of motorcycle in the final rule to be any 2- wheeled vehicle or any 3-wheeled vehicle with a curb mass less than or equal to 680 kilograms (1499 pounds). Any 3-wheeled vehicle over that weight would be classified and regulated as a passenger car. The weight was chosen because it was typical of the weight of 3-wheeled motor vehicles available on the market at that time, and did not approach the weight of light duty vehicles of the time. --------------------------------------------------------------------------- \1\ On October 22, 1975, a Notice of Proposed Rulemaking (NPRM) was published in the Federal Register (40 FR 49496) for the control of exhaust and crankcase emissions from new motorcycles. In the NPRM, ``motorcycle'' was proposed to be defined as ``any motor vehicle designed to operate on not more than three wheels (including any tricycle arrangement) in contact with the ground which is not a passenger car or passenger car derivative.'' --------------------------------------------------------------------------- In 1995, EPA was informed by a manufacturer of 3-wheeled vehicles that a competitor was allegedly selling vehicles over the weight limit, and that the manufacturer also wished to produce heavier 3-wheeled vehicles. The market for 3-wheeled vehicles, according to the manufacturer, was demanding more amenities which added weight, such as air conditioning, power windows, etc. EPA was requested to consider raising the weight limit to accommodate the market demand. EPA's primary concern with such a change is that there is not much room for increase before there would be overlap between motorcycles and light duty vehicles. Raising the weight limit significantly could result in allowing a 3-wheeled vehicle to pollute much more than a car when it could weigh as much as a car, have all the amenities of a car, and be used much in the same way as a car. This would not be in keeping with the CAA mandate to consider the need to achieve equivalency of emission reductions between motorcycles and other motor vehicles to the maximum extent practicable. EPA believes it is appropriate to propose raising the weight limit to 1749 pounds because it is still low enough to preclude creating a new market for 3-wheeled vehicles being built as passenger cars.2 The 1749 pound limit is about 60 pounds lower than the lowest weight passenger car being sold in the U.S. today and is substantially lower than the average weight of about 2900 pounds for the sub-compact class of cars sold in the U.S. --------------------------------------------------------------------------- \2\ Currently, 3-wheeled vehicles are primarily used in special applications, such as police use, postal service, and recreation- type use. --------------------------------------------------------------------------- EPA acknowledges that market-driven changes can occur in the automotive [[Page 30293]] industry, and that it should accommodate such changes to the extent practicable, providing that emission and health benefits are not compromised. It is EPA's opinion that the number of 3-wheeled vehicles affected by this action (i.e., falling between 1499 pounds and 1749 pounds) is going to be very small. Currently, EPA is aware of only two companies certifying 3-wheeled vehicles (Cushman and Westward Industries, Inc.), with a combined annual 3-wheeled vehicle production of less than 1000 units. Furthermore, these affected vehicles are substantially similar to and likely to be used much in the same way as those 3-wheeled vehicles previously regulated as motorcycles. Therefore, EPA believes that increasing the weight limit for 3-wheeled vehicles by 250 pounds will not compromise air quality or health benefits based on the current market for these vehicles. The health benefits currently achieved by the motorcycle emission standards are anticipated to remain, and not be adversely impacted by raising the weight limit of 3-wheeled vehicles. EPA requests comments about the potential for the weight increase to substantially increase the number of such vehicles being sold in the U.S., or the manner in which they are used. II. Requirements of the Proposed Rule EPA is proposing to increase the weight limit for 3-wheeled motorcycles from 1,499 pounds (680 Kg) to 1,749 pounds (793 Kg). EPA is also amending the motorcycle testing procedures to account for the increase in weight. III. Discussion of Issues A. Impact on automotive industry The Agency believes that today's proposal will not create a new market for 3-wheeled vehicles that are similar to automobiles but can be certified as motorcycles, primarily because the weight increase being proposed is small, the sales volume of these vehicles is small, and the additional weight is not overlapping with weights of light duty passenger cars. However, the Agency has some concerns that the proposed weight increase may create the possibility that smaller 4-wheeled vehicles could be converted into 3-wheeled passenger vehicles for the purposes of circumventing light duty vehicle emissions standards, and requests comments on this issue. If, during the comment period, new information comes to light about additional 3-wheeled vehicles being introduced into the U.S. market as a result of the increased weight limit, EPA may reconsider or revise this proposal. B. Revisions to test procedures. The original test procedures for motorcycles included a table to determine the road load force and inertia weight used for dynamometer testing. This table included values for loaded vehicle mass of up to 760 Kg. With today's proposal, the table has been expanded to included values for loaded vehicle mass up to 870 Kg. To arrive at the values added to this table, EPA extrapolated the data from the existing table. An option exists in the current regulations which allows the manufacturer to perform an actual vehicle road load measurement as outlined under 40 CFR 86 Sec. 529(c), which EPA is not proposing to change. IV. Cost Effectiveness No added costs will be incurred by the manufacturers of 3-wheeled vehicles as a result of this proposal. The proposed weight change will allow manufacturers to produce heavier 3-wheeled vehicles, presumably allowing them to add options which will make the vehicles more marketable. Based on EPA's current knowledge about the size of the affected market, the ramifications on emissions are likely to be very small. By increasing the weight limit, 3-wheeled vehicles weighing between 1499 and 1749 pounds will now be permitted to comply with motorcycle standards, rather than the light duty vehicles standards, which are significantly more stringent. (It should be noted that to date, no 3- wheeled vehicles have been certified to light duty vehicle standards.) EPA requests comments on the potential impact of the proposal on future production of 3-wheeled vehicles. V. Public Participation A. Comments and the Public Docket EPA requests comments on all aspects of this proposed Rulemaking. Commenters are especially encouraged to give suggestions for changing any aspects of the proposal. All comments, with the exception of proprietary information should be addressed to the EPA Air Docket Section, Docket No. A-96-49 (see ADDRESSES). Commenters who wish to submit proprietary information for consideration should clearly separate such information from other comments by (1) labeling proprietary information ``Confidential Business Information'' and (2) sending proprietary information directly to the contact person listed (see FOR FURTHER INFORMATION CONTACT) and not to the public docket. This will help insure that proprietary information is not inadvertently placed in the docket. If a commenter wants EPA to use a submission labeled as confidential business information as part of the basis for the final rule, then a nonconfidential version of the document, which summarizes the key data or information, should be sent to the docket. Information covered by a claim of confidentiality will be disclosed by EPA only to the extent allowed and by the procedures set forth in 40 CFR Part 2. If no claim of confidentiality accompanies the submission when it is received by EPA, the submission may be made available to the public without notifying the commenters. B. Public Hearing EPA will conduct a public hearing if one is requested, as discussed in the DATES section above. Anyone wishing to present testimony about this proposal at the public hearing should, if possible, notify the contact person (see FOR FURTHER INFORMATION CONTACT) at least seven days prior to the day of the hearing. The contact person should be given an estimate of the time required for the presentation of testimony and notification of any need for audio/visual equipment. Testimony will be scheduled on a first come, first served basis. A sign-up sheet will be available at the registration table the morning of the hearing for scheduling those who have not notified the contact earlier. This testimony will be scheduled on a first come, first served basis to follow the previously scheduled testimony. EPA requests that approximately 50 copies of the statement or material to be presented be brought to the hearing for distribution to the audience. In addition, EPA would find it helpful to receive an advanced copy of any statement or material to be presented at the hearing at least one week before the scheduled hearing date. This is to give EPA staff adequate time to review such material before the hearing. Such advanced copies should be submitted to the contact person listed. The official records of the hearing will be kept open for 30 days following the hearing to allow submission of rebuttal and supplementary testimony. All such submittals should be directed to the Air Docket Section, Docket No. A-96-49 (see ADDRESSES). The hearing will be conducted informally, and technical rules of evidence will not apply. A written transcript of the hearing will be placed in the above docket for review. Anyone desiring to purchase a copy of the transcript should make individual arrangements with the court reporter recording the proceedings. [[Page 30294]] VI. Administrative Requirements A. Executive Order 12866 Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Agency must determine whether the regulatory action is ``significant'' and therefore subject to OMB review and the requirements of the Executive Order. The Order defines ``significant regulatory action'' as one that is likely to result in a rule that may: (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities; (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or, (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order. It has been determined that this rule is not a ``significant regulatory action'' under the terms of Executive Order 12866 and is therefore not subject to OMB review. B. Reporting and Recordkeeping Requirements This regulation does not impose any new information collection requirements and results in no change to the currently approved collection. The Office of Management and Budget (OMB) has approved the information collection requirements contained in this rule under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2060-0104. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. An Agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15. C. Impact on Small Entities EPA has determined that it is not necessary to prepare a draft regulatory flexibility analysis in connection with this proposed rule. This rule will not have a significant adverse economic impact because it will increase the weight limit on these vehicles, thereby allowing the manufacturers of three-wheeled vehicles to produce these vehicles within the weight limit of 1749 pounds (793 Kg). This weight increase will allow manufacturers of vehicles near the existing limit of 1499 pounds (680 Kg) to provide more options on those vehicles and thus share the existing market with competing entities fairly. EPA has identified only two manufacturers currently manufacturing such vehicles. Therefore, the Administrator certifies that this regulation does not have a significant impact on a substantial number of small entities. D. Unfunded Mandates Act Under section 202 of the Unfunded Mandates Reform Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA must prepare a budgetary impact statement to accompany any proposed or final rule that includes a Federal mandate that may result in estimated costs to State, local, or tribal governments in the aggregate; or to the private sector, or $100 million or more. Under Section 205, EPA must select the most cost effective and least burdensome alternative that achieves the objectives of the rule and is consistent with statutory requirements. Section 203 requires EPA to establish a plan for informing and advising any small governments that may be significantly or uniquely impacted by the rule. EPA has determined that the final approval action promulgated today does not include a Federal mandate that may result in estimated costs of $100 million or more to either State, local, or tribal governments in the aggregate, or to the private sector. List of Subjects in 40 CFR Part 86 Environmental protection, Administrative practice and procedure, Motor vehicle pollution. Dated: May 23, 1997. Carol M. Browner, Administrator.

---------------------------------------------------------------------------------------------------------------- (c) The dynamometer shall be adjusted to reproduce the specified road load as determined by the most recent calibration. Alternatively, the actual vehicle road load can be measured and duplicated: (1) Make at least 5 replicate coastdowns in each direction from 70 to 60 km/h on a smooth, level track under balanced wind conditions. The driver must have a mass of 80 10 kg and be in the normal driving position. Record the coastdown time. (2) Average the coastdown times. Adjust the dynamometer load so that the coastdown time is duplicated with the vehicle and driver on the dynamometer. (3) Alternate procedures may be used if approved in advance by the Administrator.
