United States on the highways, other than a vehicle designed or used for military field training, combat, or tactical purposes.

(2) "Inherently low-polluting vehicle" means any low-emission vehicle which is powered by a propulsion system which does not require control devices, for exhaust emissions, external to the engine.

(3) "Anticipated certification period" means the 1-year period which begins 270 days after submission of a completed certification application to the Administrator.

(4) "Model year" as used in this subpart shall have the same meaning as that term has under section 202(b) (3) (A) (i) of the Clean Air Act.

(5) "Light duty motor vehicle" as used in this subpart means a motor vehicle which may be a suitable substitute for a class or model of light duty motor vehicles as defined at $85.002(a) (5). § 85.1602 Low-emission vehicle.

(a) A "low-emission vehicle" for the purpose of being certified as a suitable substitute for any class or model of light duty motor vehicles means any motor vehicle for which a completed certification application has been filed in accordance with § 85.1603 and which

(1) Meets the most stringent crankcase emission and fuel evaporative standards which will apply under section 202 of the Clean Air Act during any part of the anticipated certification period to motor vehicles of that type; and

(2) Produces exhaust emissions of (i) hydrocarbons or carbon monoxide which meet the emission standards applicable under section 202 of the Act to model year 1975 gasoline-fueled light duty vehicles, or (ii) oxides of nitrogen which meet the emission standard applicable under section 202 to model year 1976 gascline-fueled light duty vehicles; and

(3) Does not exceed the following exhaust emission standards:

(i) Hydrocarbons. 3 grams per vehicle mile:

(ii) Carbon monoxide. 28 grams per vehicle mile;

(iii) Oxides of nitrogen. 3.1 grams per vehicle mile; and

(4) Emits no air pollutant other than those pollutants which are emitted by any class or model of motor vehicles for which the applicant vehicle may be a suitable substitute. unless the Administrator determines that such other emis

sions will not contribute significantly to air pollution which causes or contributes to the endangerment of public health or welfare; and

(5) Does not significantly increase the emissions of any air pollutant not subject to an emission standard under section 202 of the Act by comparison to the emissions of such pollutant by any class or model of motor vehicles for which the applicant vehicle may be a suitable substitute.

(b) The applicable test procedures for determining compliance with the standards established by paragraph (a) of this section shall be those in effect under section 202 of the Act for 1975 model year gasoline-fueled light duty motor vehicles, except as provided in § 85.1603(b). [37 FR 24315, Nov. 15, 1972, as amended at 38 FR 17167, June 28, 1973]

§ 85.1603 Application for certification.

(a) Any person desiring certification of a test vehicle under section 212 of the Clean Air Act shall submit to the Administrator a notice of intent to submit a certification application with respect to such vehicle. The notice of intent shall contain a description of the vehicle, including the propulsion system and the fuel used by it, and such other information as the Administrator may request. The Administrator will transmit a copy of the notice of intent to the LowEmission Vehicle Certification Board.

(b) As soon as practicable after receipt of a notice of intent to submit a certification application for a vehicle, the Administrator shall determine whether the test procedures required under § 85.1602(b) are applicable to that vehicle. If he determines they are inapplicable, he shall, as soon as practicable thereafter, prescribe test procedures for determining whether such vehicle is a low-emission vehicle, and, if necessary, he shall establish emission standards equivalent to those in effect under paragraph (a) of § 85.1602. He shall also select test vehicles in accordance with § 85.1603.

(c) After completion of testing of all test vehicles in accordance with applicable test procedures and with § 85.1604, the person desiring certification shall submit to the Administrator a written application signed by an authorized representative of the applicant. The application shall contain all emission data from the tests of the emission and dura

bility data test vehicles and all data required by the Board under § 400.4 of this title, relative to the following vehicle characteristics:

(1) Safety;

(2) Performance characteristics;
(3) Reliability potential;

(4) Serviceability;

(5) Fuel availability;

(6) Noise level; and

(7) Maintenance costs.

(d) Any certification application must be filed prior to July 8, 1972, in order for that vehicle to be eligible for certification, except that the Administrator may, after consultation with the Board, accept an application filed no later than December 31, 1972, if he determines that it is likely that the Board will be able to make the determination required by § 400.6 of this title no later than April 2, 1973.

(e) In addition to the information required under this section, and under $ 400.4 of this title, the Administrator may require the applicant to submit any other information which the Administrator deems necessary in determining whether the test vehicle is a low-emission vehicle. The application for certification may be considered incomplete, unless all information required by the Administrator and the Low-Emission Vehicle Certification Board has been submitted.

(f) The Administrator shall, immediately upon receipt of a completed application for certification under paragraph (c) of this section, publish in the FEDERAL REGISTER notice of receipt of the application, the name of the applicant, a brief description of the propulsion system and fuel used by the applicant vehicle, and information concerning the method by which the public may have access to data relating to the emission characteristics of the applicant vehicle.

§ 85.1604 Test vehicle selection.

(a) The test vehicles covered by the application for certification shall be divided into engine families in accordance with § 85.073-5(a) (2) unless the Administrator approves an alternative procedure under § 85.1603 (b).

(b) Except as the Administrator may require pursuant to § 85.1603(b), the applicant shall test or cause to be tested two durability data vehicles of each engine-system combination and four emission data vehicles of each engine family described in the notice of intent. The test

(a) All data on emission data and durability data test vehicles shall be reported in accordance with §§ 85.073-4(a), and 85.073-20 (d).

(b) For the purpose of this subpart, § 85.073-7(e) shall not apply.

§ 85.1606 Testing by the Administrator. The Administrator may require that any one or more of the applicant's test vehicles be submitted to him, at such place or places and at such time or times as he may designate for the purpose of conducting emission tests.

(a) The Administrator shall, within 90 days after receipt of a completed application for certification, determine whether the applicant vehicle is a lowemission vehicle. Such determination shall be based upon an evaluation of the data provided to the Administrator in the application for certification, any supporting information the Administrator may obtain from the applicant, any relevant information obtained from the public, and the results of any testing the Administrator may have conducted in accordance with § 85.1606.

(b) The Administrator shall, immediately upon making the determination required in paragraph (a) of this section, publish in the FEDERAL REGISTER notice of such determination and the reasons therefor.

(c) The Administrator may make any recommendation which he deems appropriate concerning whether any applicant vehicle is an inherently low-polluting vehicle.

(d) If at any time after making an affirmative determination under paragraph (a) of this section but prior to certification by the Board, the Administrator obtains information which demonstrates that the applicant vehicle is not a low-emission vehicle, he may revoke such determination. The Administrator must immediately thereafter notify the Board and publish in the FEDERAL REGISTER notice of such revocation and the reasons therefor.
