PART 86—CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES AND ENGINES
§ 86.153-98   Vehicle and canister preconditioning; refueling test.
(a) Vehicle and canister preconditioning. Vehicles and vapor storage canisters shall be preconditioned in accordance with the preconditioning procedures for the supplemental two-diurnal evaporative emissions test specified in § 86.132-96 (a) through (j). For vehicles equipped with non-integrated refueling emission control systems, the canister must be loaded using the method involving butane loading to breakthrough (see § 86.132-96(j)(1)).
(b) Seal test. The Administrator may choose to omit certain canister load and purge steps, and replace them with a bench purge of the refueling canister(s), in order to verify the adequacy of refueling emission control system seals. Failure of this seal test shall constitute a failure of the refueling emission control test. For integrated systems, this bench purge may be performed after the exhaust testing in order to obtain exhaust emission test results. Non-integrated system seal testing shall be performed using paragraph (b)(1) of this section.
(1) Without the exhaust emission test. The Administrator may conduct the canister preconditioning by purging the canister(s) with at least 1200 canister bed volumes of ambient air (with humidity controlled to 50±25 grains of water vapor per pound of dry air) maintained at a nominal flow rate of 0.8 cfm directly following the preconditioning drive described in § 86.132-96 (c) through (e). In this case, the canister loading procedures and the vehicle driving procedures described in § 86.132-96 (f) through (j) and in paragraphs (c) through (d) of this section shall be omitted, and the 10 minute and 60 minute time requirements of paragraph (e) of this section shall apply to time after completion of the bench purge. In the case of multiple refueling canisters, each canister shall be purged separately.
(2) With the exhaust emission test. The Administrator may conduct the canister preconditioning by purging the canister(s) directly after the exhaust test (see paragraph (c)(1) of this section). The canister shall be purged with at least 1200 canister bed volumes of ambient air (with humidity controlled to 50±25 grains of water vapor per pound of dry air) maintained at a nominal flow rate of 0.8 cfm. In this case, the vehicle driving procedures described in paragraphs (c)(2) through (d) of this section shall be omitted, and the 10 minute and 60 minute time requirements of paragraph (e) of this section shall apply to time after completion of the bench purge. In the case of multiple refueling canisters, each canister shall be purged separately.
(3) Manufacturers may use the procedures described in this paragraph (b) to demonstrate compliance with the seal test for vehicles with fuel tanks exceeding 35 gallons nominal fuel tank capacity, and for any incomplete vehicles.
(c) Canister purging; integrated systems. (1) Vehicles to be tested for exhaust emissions only shall be processed according to §§ 86.135-94 through 86.137-96. Vehicles to be tested for refueling emissions shall be processed in accordance with the procedures in §§ 86.135-94 through 86.137-96, followed by the procedures outlined in paragraph (c)(2) of this section.
(2) To provide additional opportunity for canister purge, conduct additional driving on a dynamometer, within one hour of completion of the hot start exhaust test, by operating the test vehicle through one UDDS, a 2 minute idle, two NYCCs, another 2 minute idle, another UDDS, then another 2 minute idle (see § 86.115-78 and appendix I of this part). Fifteen seconds after the engine starts, place the transmission in gear. Twenty seconds after the engine starts, begin the initial vehicle acceleration of the driving schedule. The transmission shall be operated according to the specifications of § 86.128-79 during the driving cycles. The vehicle's air conditioner (if so equipped) shall be turned off. Ambient temperature shall be controlled as specified in § 86.151-98. It is not necessary to monitor and/or control in-tank fuel temperatures.
(i) The fixed-speed fan specified in § 86.135-94(b) may be used for engine cooling. If a fixed-speed fan is used, the vehicle's hood shall be opened.
(ii) Alternatively, the roadspeed-modulated fan specified in § 86.107-96(d)(1) may be used for engine cooling. If a road-speed modulated fan is used, the vehicle's hood shall be closed.
(d) Canister purging: non-integrated systems. Within one hour of completion of canister loading to breakthrough, the fuel tank(s) shall be further filled to 95 percent of nominal tank capacity determined to the nearest one-tenth of a U.S. gallon (0.38 liter) with the fuel specified in § 86.113-94. During this fueling operation, the refueling emissions canister(s) shall be disconnected, unless the manufacturer specifies that the canister(s) should not be disconnected. Following completion of refueling, the refueling emissions canister(s) shall be reconnected, if the canister was disconnected during refueling. Special care shall be taken during this step to avoid damage to the components and the integrity of the fuel system. Vehicle driving to purge the refueling canister(s) shall be performed using either the chassis dynamometer procedure or the test track procedure, as described in paragraphs (d)(1) and (d)(2) of this section. The Administrator may choose to shorten the vehicle driving for a partial refueling test as described in paragraph (d)(3) of this section. For vehicles equipped with dual fuel tanks, the required volume of fuel shall be driven out of one tank, the second tank shall be selected as the fuel source, and the required volume of fuel shall be driven out of the second tank.
(1) Chassis dynamometer procedure. (i) Vehicle driving on a chassis dynamometer shall consist of repeated drives with the UDDS until 85 percent of fuel tank capacity has been consumed. Driving in testing performed by manufacturers may be terminated before 85 percent of the fuel tank capacity has been consumed, provided that driving is not terminated partway through a UDDS cycle. Driving in testing performed by the Administrator may be terminated after the same number of UDDS cycles as driven in the manufacturer's certification testing.
(ii) Except with the advance approval of the Administrator, the number of UDDSs required to consume 85 percent of tank fuel capacity (total capacity of both tanks when the vehicle is equipped with dual fuel tanks) shall be determined from the fuel economy on the UDDS applicable to the test vehicle and from the number of gallons to the nearest 0.1 gallon (0.38 liter) that constitutes 85 percent of tank volume. If this “fuel consumed point” occurs partway through a UDDS cycle, the cycle shall be completed in its entirety.
(iii) For vehicles equipped with dual fuel tanks, fuel switching from the first tank to the second tank shall occur at the 10 percent volume of the first tank regardless of the point in the UDDS cycle at which this occurs.
(iv) If necessary to accommodate work schedules, the engine may be turned off and the vehicle parked on the dynamometer. The vehicle may be parked off of the dynamometer to facilitate maintenance or repairs if required.
(v) During the driving on the dynamometer, a cooling fan(s) shall be positioned as described in § 86.135-94(b).
(2) Test track procedure. (i) Vehicle driving on a test track shall consist of repeated drives with the UDDS until 85 percent of fuel tank capacity has been consumed. Driving performed by manufacturers may be terminated before 85 percent of the fuel tank capacity has been consumed, provided that driving is not terminated partway through a UDDS cycle. Driving performed by the Administrator may be terminated after the same number of UDDS cycles as driven in the manufacturer's certification testing.
(ii) If the distance from the emission laboratory to the test track is less than 5 miles (8.05 km) the vehicle may be driven to the test track at a speed not to exceed 25 mph. If the distance is greater than 5 miles (8.05 km) the vehicle shall be moved to the test track with the engine off.
(iii) Except with the advance approval of the Administrator, the number of UDDSs required to consume 85 percent of tank fuel capacity (total capacity of both tanks when the vehicle is equipped with dual fuel tanks) shall be determined from the fuel economy on the UDDS applicable to the test vehicle and from the number of gallons to the nearest 0.1 gallon (0.38 liter) that constitutes 85 percent of tank volume. If this “fuel consumed point” occurs partway through a UDDS cycle, the cycle shall be completed in its entirety.
(iv) The vehicle shall be driven at a speed not to exceed 25 mph from the test track to the laboratory provided the distance from the test track to the laboratory does not exceed 5 miles (8.05 km). If the distance from the test track to the emission laboratory is greater than 5 miles (8.05 km) the vehicle shall be moved from the test track with the engine off.
(v) For vehicles equipped with dual fuel tanks, fuel switching from the first tank to the second tank shall occur at the 10 percent volume of the first tank regardless of the point in the UDDS cycle at which this occurs.
(vi) If necessary to accommodate work schedules, the engine may be turned off and the vehicle parked on the test track. The vehicle may be parked off of the test track to facilitate maintenance or repairs if required. If the vehicle is moved from the test track, it shall be returned to the track with the engine off when mileage accumulation is to be resumed.
(3) Drive schedule for partial refueling test. The Administrator may conduct a partial refueling test involving a shortening of the drive procedures described in paragraphs (d) (1) and (2) of this section and a modified soak and refueling procedure as described in paragraph (e) of this section and § 86.154-98(e)(7)(i). The drive shall be performed as described in paragraph (d) (1) or (2) of this section except that the drive shall be terminated when at least 10 percent but no more than 85 percent of the fuel tank nominal capacity has been consumed and not partway through a UDDS cycle. The amount of fuel consumed in the drive shall be determined by multiplying the number of UDDSs driven by the mileage accumulated per UDDS and dividing by the fuel economy for the UDDS applicable to the test vehicle.
(e) Vehicle cool down —(1) Partial refueling test. If the Administrator is conducting the non-integrated system partial refueling test, after the driving procedure specified in paragraph (d)(3) of this section, the vehicle shall be parked (without starting the engine) and soaked at 80±3 °F (27±1.7 °C) for a minimum of 1 hour and a maximum of 6 hours.
(2) For all other refueling emission tests. Within 10 minutes of completion of refueling emissions canister stabilization (see paragraph (c) or (d) of this section), the refueling emissions canister(s) shall be disconnected, unless the manufacturer specifies that the refueling canister(s) should not be disconnected. Within 60 minutes of completion of refueling emissions canister stabilization (see paragraph (c) or (d) of this section), the vehicle fuel tank(s) shall be drained, the fuel tank(s) fueled to 10 percent of nominal tank capacity determined to the nearest one-tenth of a U.S. gallon (0.38 liter) with the specified fuel, and the vehicle parked (without starting the engine) and soaked at 80±3 °F (27±1.7 °C) for a minimum of 6 hours and a maximum of 24 hours.
§ 86.154-98   Measurement procedure; refueling test.
(a) The refueling test measurement procedure described in this section immediately follows the vehicle and canister preconditioning described in § 86.153-98.
(b) The refueling emission enclosure shall be purged for several minutes immediately prior to the test. Warning: If at any time the concentration of hydrocarbons, of methanol, or of methanol and hydrocarbons exceeds 15,000 ppm C, the enclosure should be immediately purged. This concentration provides a 4:1 safety factor against the lean flammability limit.
(c)(1) The FID (or HFID) hydrocarbon analyzer, and additional analyzer, if needed, shall be zeroed and spanned immediately prior to the test.
(2) For methanol-fueled vehicles only, impingers charged with known volumes of pure deionized water shall be placed in the methanol sampling system.
(d) If not already on, the enclosure mixing fan and the spilled fuel mixing blower shall be turned on at this time.
(e) The refueling emission measurement portion of the refueling test shall be performed as follows:
(1) The line from the fuel tank(s) to the refueling emissions canister(s) shall be connected.
(2) The test vehicle, with the engine shut off, shall be moved into the enclosure. The test vehicle windows and luggage compartment shall be opened if not already open.
(3) An electrical ground shall be attached to the vehicle. The vehicle fuel filler cap shall be removed and the enclosure door shall be closed and sealed within two minutes of cap removal. The FID (or HFID) trace shall be allowed to stabilize.
(4) The dispensed fuel temperature recording system shall be started.
(5)(i) Within 10 minutes of closing and sealing the doors, analyze enclosure atmosphere for hydrocarbons and record. This is the initial (time = 0 minutes) hydrocarbon concentration, C HCi , required in § 86.143-96.
(ii) For methanol-fueled vehicles only, measure the initial concentration of methanol as described in § 86.133-96(i)(6).
(6) Within one minute of obtaining the initial FID (or HFID) reading, and methanol reading if applicable, the fuel nozzle shall be inserted into the filler neck of the test vehicle, to its maximum penetration, and the refueling operation shall be started. The plane of the nozzle's handle shall be approximately perpendicular to the floor of the laboratory. The fuel shall be dispensed at a temperature of 67±1.5 °F (19.4±0.8 °C) and at a dispensing rate of 9.8±0.3 gal/min (37.1±1.1 liter/min). In testing conducted by the Administrator, a lower dispensing rate (no lower than 4.0 gal/min (15.1 liter/min)) may be used.
(7)(i) Partial refueling test. If the Administrator conducts the non-integrated system partial refueling test, the fuel flow shall continue until the amount of fuel pumped is equal to the fuel consumed during the driving, as determined in accordance with § 86.153-98(d)(3). The final volume of fuel dispensed must be within one-tenth of a U.S. gallon (0.38 liter) of the targeted amount. If automatic nozzle shut-off occurs prior to this point, the nozzle shall be reactivated within 15 seconds and fuel dispensing continued as needed. A minimum of 3 seconds shall elapse between any automatic shutoff and subsequent resumption of dispensing.
(ii) For all other refueling tests. The fuel flow shall continue until the refueling nozzle automatic shut-off is activated. The amount of fuel dispensed must be at least 85 percent of nominal fuel tank volume, determined to the nearest one-tenth of a U.S. gallon (0.38 liter). If automatic nozzle shut-off occurs prior to this point, the nozzle shall be reactivated within 15 seconds and fuel dispensing continued as needed. A minimum of 3 seconds shall elapse between any automatic shutoff and subsequent resumption of dispensing. Dispensing may not be manually terminated, unless the test vehicle has already clearly failed the test.
(8)(i) The final reading of the evaporative enclosure FID analyzer shall be taken 60±5 seconds following the final shut-off of fuel flow. This is the final hydrocarbon concentration, C HCf , required in § 86.143-96. The elapsed time, in minutes, between the initial and final FID (or HFID) readings shall be recorded.
(ii) For methanol-fueled vehicles only. Measure the final concentration of methanol as described in § 86.133-96(m)(2).
(9) For vehicles equipped with more than one fuel tank, use good engineering judgment to apply the procedures described in this section for each fuel tank.

The procedures described in §§ 86.158-00, 86.159-00, 86.160-00, and 86.162-00 discuss the aggressive driving (US06) and air conditioning (SC03) elements of the Supplemental Federal Test Procedures (SFTP). These test procedures consist of two separable test elements: A sequence of vehicle operation that tests exhaust emissions with a driving schedule (US06) that tests exhaust emissions under high speeds and accelerations (aggressive driving); and a sequence of vehicle operation that tests exhaust emissions with a driving schedule (SC03) which includes the impacts of actual air conditioning operation. These test procedures (and the associated standards set forth in subpart S of this part) are applicable to light-duty vehicles and light-duty trucks.
(a) Vehicles are tested for the exhaust emissions of THC, CO, NO X . CH 4 , and CO 2 . For diesel-cycle vehicles, THC is sampled and analyzed continuously according to the provisions of § 86.110.
(b) Each test procedure follows the vehicle preconditioning specified in § 86.132-00.
(c) US06 Test Cycle. The test procedure for emissions on the US06 driving schedule (see § 86.159-00) is designed to determine gaseous exhaust emissions from light-duty vehicles and light-duty trucks while simulating high speed and acceleration on a chassis dynamometer (aggressive driving). The full test consists of preconditioning the engine to a hot stabilized condition, as specified in § 86.132-00, and an engine idle period of 1 to 2 minutes, after which the vehicle is accelerated into the US06 cycle. A proportional part of the diluted exhaust is collected continuously for subsequent analysis, using a constant volume (variable dilution) sampler or critical flow venturi sampler.
(d) SC03 Test Cycle. The test procedure for determining exhaust emissions with the air conditioner operating (see § 86.160-00) is designed to determine gaseous exhaust emissions from light-duty vehicles and light-duty trucks while simulating an urban trip during ambient conditions of 95 °F, 100 grains of water/pound of dry air (approximately 40 percent relative humidity), and a solar heat load intensity of 850 W/m 2 . The full test consists of vehicle preconditioning (see § 86.132-00 paragraphs (o) (1) and (2)), an engine key-off 10 minute soak, an engine start, and operation over the SC03 cycle. A proportional part of the diluted exhaust is collected continuously during the engine start and the SC03 driving cycle for subsequent analysis, using a constant volume (variable dilution) sampler or critical flow venturi sampler.
(e) The emission results from the aggressive driving test (§ 86.159-00), air conditioning test (§ 86.160-00), and a FTP test (§ 86.130-00 (a) through (d) and (f)) (conducted on a large single roll or equivalent dynamometer) are analyzed according to the calculation methodology in § 86.164-00 and compared to the applicable SFTP emission standards in subpart A of this part (§§ 86.108-00 and 86.109-00).

§ 86.158-08   Supplemental Federal Test Procedures; overview.
The procedures described in §§ 86.158-08, 86.159-08, 86.160-00, and 86.162-00 discuss the aggressive driving (US06) and air conditioning (SC03) elements of the Supplemental Federal Test Procedures (SFTP). These test procedures consist of two separable test elements: A sequence of vehicle operation that tests exhaust emissions with a driving schedule (US06) that tests exhaust emissions under high speeds and accelerations (aggressive driving); and a sequence of vehicle operation that tests exhaust emissions with a driving schedule (SC03) which includes the impacts of actual air conditioning operation. These test procedures (and the associated standards set forth in subpart S of this part) are applicable to light-duty vehicles and light-duty trucks.
(a) Vehicles are tested for the exhaust emissions of THC, CO, NO X , CH 4 , and CO 2 . For diesel-cycle vehicles, THC is sampled and analyzed continuously according to the provisions of § 86.110.
(b) Each test procedure follows the vehicle preconditioning specified in § 86.132-00.
(c) US06 Test Cycle. The test procedure for emissions on the US06 driving schedule (see § 86.159-08) is designed to determine gaseous exhaust emissions from light-duty vehicles and light-duty trucks while simulating high speed and acceleration on a chassis dynamometer (aggressive driving). The full test consists of preconditioning the engine to a hot stabilized condition, as specified in § 86.132-00, and an engine idle period of 1 to 2 minutes, after which the vehicle is accelerated into the US06 cycle. A proportional part of the diluted exhaust is collected continuously for subsequent analysis, using a constant volume (variable dilution) sampler or critical flow venturi sampler. Optionally, as specified in § 86.159-08 and in part 600 of this chapter, a proportional part of the diluted exhaust may be collected continuously in two bag samples, one representing US06 City driving and the other representing US06 Highway driving. If two bag samples are collected, for petroleum-fueled diesel-cycle vehicles for which THC is sampled and analyzed continuously according to the provisions of § 86.110, the analytical system shall be configured to calculate THC for the US06 City phase and the US06 Highway phase as described in § 86.159-08.
(d) SC03 Test Cycle. The test procedure for determining exhaust emissions with the air conditioner operating (see § 86.160-00) is designed to determine gaseous exhaust emissions from light-duty vehicles and light-duty trucks while simulating an urban trip during ambient conditions of 95 °F, 100 grains of water/pound of dry air (approximately 40 percent relative humidity), and a solar heat load intensity of 850 W/m 2 . The full test consists of vehicle preconditioning (see § 86.132-00 paragraphs (o)(1) and (2)), an engine key-off 10 minute soak, an engine start, and operation over the SC03 cycle. A proportional part of the diluted exhaust is collected continuously during the engine start and the SC03 driving cycle for subsequent analysis, using a constant volume (variable dilution) sampler or critical flow venturi sampler.
(e) The emission results from the aggressive driving test (§ 86.159-08), air conditioning test (§ 86.160-00), and FTP test (§ 86.130-00 (a) through (d) and (f)) (conducted on a large single roll or equivalent dynamometer) are analyzed according to the calculation methodology in § 86.164-08 and compared to the applicable SFTP emission standards in subpart S of this part.
(f) These test procedures may be run in any sequence that maintains the applicable preconditioning elements specified in § 86.132-00.
§ 86.159-00   Exhaust emission test procedures for US06 emissions.
(a) Overview. The dynamometer operation consists of a single, 600 second test on the US06 driving schedule, as described in appendix I, paragraph (g), of this part. The vehicle is preconditioned in accordance with § 86.132-00, to bring it to a warmed-up stabilized condition. This preconditioning is followed by a 1 to 2 minute idle period that proceeds directly into the US06 driving schedule during which continuous proportional samples of gaseous emissions are collected for analysis. If engine stalling should occur during cycle operation, follow the provisions of § 86.136-90 (engine starting and restarting). For gasoline-fueled Otto-cycle vehicles, the composite samples collected in bags are analyzed for THC, CO, CO 2 , CH 4 , and NO X . For petroleum-fueled diesel-cycle vehicles, THC is sampled and analyzed continuously according to the provisions of § 86.110. Parallel bag samples of dilution air are analyzed for THC, CO, CO 2 , CH 4 , and NO X .
(b) Dynamometer activities. (1) All official US06 tests shall be run on a large single roll electric dynamometer, or an approved equivalent dynamometer configuration, that satisfies the requirements of § 86.108-00.
(2) Position (vehicle can be driven) the test vehicle on the dynamometer and restrain.
(3) Required US06 schedule test dynamometer inertia weight class selections are determined by the test vehicles test weight basis and corresponding equivalent weight as listed in the tabular information of § 86.129-94(a) and discussed in § 86.129-00 (e) and (f).
(4) Set the dynamometer test inertia weight and roadload horsepower requirements for the test vehicle (see § 86.129-00 (e) and (f). The dynamometer's horsepower adjustment settings shall be set to match the force imposed during dynamometer operation with actual road load force at all speeds.

§ 86.159-08   Exhaust emission test procedures for US06 emissions.
(a) Overview. The dynamometer operation consists of a single, 600 second test on the US06 driving schedule, as described in appendix I, paragraph (g), of this part. The vehicle is preconditioned in accordance with § 86.132-00, to bring it to a warmed-up stabilized condition. This preconditioning is followed by a 1 to 2 minute idle period that proceeds directly into the US06 driving schedule during which continuous proportional samples of gaseous emissions are collected for analysis. US06 emissions may optionally be collected in two bag samples representing US06 City and US06 Highway emissions, as provided for in this section and in part 600 of this chapter. Emissions from seconds 0-130 and seconds 495-596 are collected in one bag to represent US06 City emissions, and emissions from seconds 130-495 are collected in a second bag to represent US06 Highway emissions. If engine stalling should occur during cycle operation, follow the provisions of § 86.136-90 (engine starting and restarting). For gasoline-fueled Otto-cycle vehicles, the composite samples collected in bags are analyzed for THC, CO, CO 2 , CH 4 , and NO X . For petroleum-fueled diesel-cycle vehicles, THC is sampled and analyzed continuously according to the provisions of § 86.110. Parallel bag samples of dilution air are analyzed for THC, CO, CO 2 , CH 4 , and NO X .
(b) Dynamometer activities. (1) All official US06 tests shall be run on a large single roll electric dynamometer, or an approved equivalent dynamometer configuration, that satisfies the requirements of § 86.108-00.

(4) Set the dynamometer test inertia weight and roadload horsepower requirements for the test vehicle according to § 86.129-00 (e) and (f). The dynamometer's horsepower adjustment settings shall be set to match the force imposed during dynamometer operation with actual road load force at all speeds.

In the case of vehicles with rear engine compartments (or if special designs make the above impractical), the cooling fan(s) shall be placed in a position to provide sufficient air to maintain vehicle cooling. The Administrator may approve modified cooling configurations, additional cooling, variable speed fan(s), and/or a closed engine compartment cover if necessary to satisfactorily perform the test. In approving requests for additional or modified cooling, the Administrator will consider such items as actual road cooling data and whether such additional cooling is needed to provide a representative test. For example, the hood may be closed to provide adequate air flow to an intercooler through a factory installed hood scoop. Additionally, the Administrator may conduct certification, fuel economy and in-use testing using the additional cooling set-up approved for a specific vehicle.
(c) The flow capacity of the CVS shall be large enough to virtually eliminate water condensation in the system.

§ 86.160-00   Exhaust emission test procedure for SC03 emissions.
(a) Overview. The dynamometer operation consists of a single, 600 second test on the SC03 driving schedule, as described in appendix I, paragraph (h), of this part. The vehicle is preconditioned, in accordance with § 86.132-00 of this subpart, to bring the vehicle to a warmed-up stabilized condition. This preconditioning is followed by a 10 minute vehicle soak (engine off) that proceeds directly into the SC03 driving schedule, during which continuous proportional samples of gaseous emissions are collected for analysis. The entire test, including the preconditioning driving, vehicle soak, and SC03 official test cycle, is either conducted in an environmental test facility or under test conditions that simulates testing in an environmental test cell (see § 86.162-00 (a) for a discussion of simulation procedure approvals). The environmental test facility must be capable of providing the following nominal ambient test conditions of: 95 °F air temperature, 100 grains of water/pound of dry air (approximately 40 percent relative humidity), a solar heat load intensity of 850 W/m 2 , and vehicle cooling air flow proportional to vehicle speed. Section 86.161-00 discusses the minimum facility requirements and corresponding control tolerances for air conditioning ambient test conditions. The vehicle's air conditioner is operated or appropriately simulated for the duration of the test procedure (except for the vehicle 10 minute soak), including the preconditioning. For gasoline-fueled Otto-cycle vehicles, the composite samples collected in bags are analyzed for THC, CO, CO 2 , CH 4 , and NO X . For petroleum-fueled diesel-cycle vehicles, THC is sampled and analyzed continuously according to the provisions of § 86.110. Parallel bag samples of dilution air are analyzed for THC, CO, CO 2 , CH 4 , and NO X .
(b) Dynamometer activities. (1) All official air conditioning tests shall be run on a large single roll electric dynamometer or an equivalent dynamometer configuration that satisfies the requirements of § 86.108-00.
(2) Position (vehicle can be driven) the test vehicle on the dynamometer and restrain.
(3) Required SC03 schedule test dynamometer inertia weight class selections are determined by the test vehicles test weight basis and corresponding equivalent weight as listed in the tabular information of § 86.129-00(a) and discussed in § 86.129-00 (e) and (f).
(4) Set the dynamometer test inertia weight and roadload horsepower requirements for the test vehicle (see § 86.129-00 (e) and (f)). The dynamometer's horsepower adjustment settings shall be set such that the force imposed during dynamometer operation matches actual road load force at all speeds.
(5) The vehicle speed as measured from the dynamometer rolls shall be used. A speed vs. time recording, as evidence of dynamometer test validity, shall be supplied at request of the Administrator.
(6) The drive wheel tires may be inflated up to a gauge pressure of 45 psi (310 kPa), or the manufacturer's recommended pressure if higher than 45 psi, in order to prevent tire damage. The drive wheel tire pressure shall be reported with the test results.
(7) The driving distance, as measured by counting the number of dynamometer roll or shaft revolutions, shall be determined for the test.
(8) Four-wheel drive and all-wheel drive vehicles may be tested either in a four-wheel drive or a two-wheel drive mode of operation. In order to test in the two-wheel drive mode, four-wheel drive and all-wheel drive vehicles may have one set of drive wheels disengaged; four-wheel and all-wheel drive vehicles which can be shifted to a two-wheel mode by the driver may be tested in a two-wheel drive mode of operation.
(c) Vehicle and test activities for testing in a full environmental cell. The SFTP air conditioning test in an environmental test cell is composed of the following sequence of activities. Alternative procedures which appropriately simulate full environmental cell testing may be approved under the provisions of §§ 86.162-00(a) and 86.163-00.
(1) Drain and fill the vehicle's fuel tank to 40 percent capacity with test fuel. If a vehicle has gone through the drain and fuel sequence less than 72 hours previously and has remained under laboratory ambient temperature conditions, this drain and fill operation can be omitted (see § 86.132-00(c)(2)(ii)).
(2)(i) Position the variable speed cooling fan in front of the test vehicle with the vehicle's hood down. This air flow should provide representative cooling at the front of the test vehicle (air conditioning condenser and engine) during the SC03 driving schedule. See § 86.161-00(e) for a discussion of cooling fan specifications.
(ii) In the case of vehicles with rear engine compartments (or if this front location provides inadequate engine cooling), an additional cooling fan shall be placed in a position to provide sufficient air to maintain vehicle cooling. The fan capacity shall normally not exceed 5300 cfm (2.50 m 3 /s). If, however, it can be demonstrated that during road operation the vehicle receives additional cooling, and that such additional cooling is needed to provide a representative test, the fan capacity may be increased or additional fans used if approved in advance by the Administrator.

§ 86.161-00   Air conditioning environmental test facility ambient requirements.
The goal of an air conditioning test facility is to simulate the impact of an ambient heat load on the power requirements of the vehicle's air conditioning compressor while operating on a specific driving cycle. The environmental facility control elements that are discussed are ambient air temperature and humidity, minimum test cell size, solar heating, and vehicle frontal air flow.
(a) Ambient air temperature. (1) Ambient air temperature is controlled, within the test cell, during all phases of the air conditioning test sequence to 95 ±2 °F on average and 95 ±5 °F as an instantaneous measurement.
(2) Air temperature is recorded continuously at a minimum of 30 second intervals. Records of cell air temperatures and values of average test temperatures are maintained by the manufacturer for all certification related programs.
(b) Ambient humidity. (1) Ambient humidity is controlled, within the test cell, during all phases of the air conditioning test sequence to an average of 100 ±5 grains of water/pound of dry air.
(2) Humidity is recorded continuously at a minimum of 30 second intervals. Records of cell humidity and values of average test humidity are maintained by the manufacturer for all certification related programs.
(c) Minimum test cell size. (1) The recommended minimum environmental exhaust emission test cell size is width 20 feet, length 40 feet, and height 10 feet.

(ii) The radiant energy intensity set point is 850 ±45 watts/square meter.
(iii) The definition of an acceptable spectral distribution is contained in the following table:
Definition of the Spectral Distribution
Note: Filter the UV region between 280 and 320 wave lengths.
(iv) The angle of incidence of radiant energy is defined as 90 degrees from the test cell floor.
(v) The requirements for measuring the uniformity of radiant energy are:
(A) The radiant energy uniformity tolerance is ±15 percent of the radiant energy intensity set point of 850 watts/square meter.
(B) The uniformity of radiant energy intensity is measured at each point of a 0.5 meter grid over the entire footprint of the test vehicle at the elevation of one meter including the footprint edges.

§ 86.163-00   Spot check correlation procedures for vehicles tested using a simulation of the environmental test cell for air conditioning emission testing.
This section is applicable for vehicles which are tested using a simulation of the environmental test cell approved under the provisions of § 86.162-00(a).
(a) The Administrator may select up to five emission data vehicles (one emission data vehicle for small volume manufacturers), including vehicles submitted for running change approval, each model year for any manufacturer undergoing the spot checking procedures of this section.
(b) Testing conducted under this section (including testing performed in an environmental test cell) will be considered as official data as described in § 86.091-29 and used in determining compliance with the standards. Such testing must comply with all applicable emission standards of subpart A of this part. Retests for the purpose of emission compliance will be allowed using the procedures described in § 86.091-29.
(c) Spot check procedures. (1) Subject to the limitations of paragraphs (a) and (d)(2)(iii) of this section, the Administrator may require that one or more of the test vehicles which use a simulation rather than actual testing in an environmental test cell for air conditioning emission testing be submitted at a place the Administrator will designate for air conditioning emission testing in an environmental test cell as described in § 86.160-00. The Administrator may order this testing to be conducted at a manufacturer facility. All manufacturers which use a simulation instead of environmental cell testing must have access to an environment test cell meeting the requirements of § 86.161-00 to perform this testing.
(2) An air conditioning emission test will be performed as described in § 86.162-00 in a full environmental test cell.
(i) The results of the original simulation test and the full environmental test cell required in paragraph (c)(1) of this section are compared. In order to pass the spot check, the test results must pass both the following two criteria:
(A) The NO X emission results of the simulation test must be at least 85% of the NO X emission results of the environmental chamber test.
(B) The fuel consumption of the simulation test must be at least 95% of the fuel consumption of the environmental chamber test.
(ii) If either of two criteria of paragraph (c)(2)(i) of this section were not met, a retest is allowed. The manufacturer may elect to conduct either a retest of the simulation procedure or the environmental chamber testing. In order to pass the spot check, the test results must pass both the following two criteria using the retest test result.
(A) The NO X emission results of the simulation test must be at least 85% of the NO X emission results of the environmental chamber test.
(B) The fuel consumption of the simulation test must be at least 95% of the fuel consumption of the environmental chamber test.
(iii) If either of the two criteria of paragraph (c)(2)(ii) of this section were not met, a second retest is allowed. The procedure not selected for the first retest must be used for the second retest, yielding two test results for each procedure. In order to pass the spot check, the test results must pass both the following two criteria using the average test result for each procedure:
(A) The NO X emission results of the simulation test must be at least 85% of the NO X emission results of the environmental chamber test.
(B) The fuel consumption of the simulation test must be at least 95% of the fuel consumption of the environmental chamber test.
(iv) If the spot check criteria have not passed after any of the initial test, the first retest, or the second retest the spot check is considered failed.
(d) Consequences of failing a spot check. (1) If the emission results of the testing using the environmental test chamber passes all the applicable standards, those test results may be used to obtain a certificate of conformity.
(2) The Administrator will allow up to 60 days for the manufacturer to supply additional data addressing the correlation of the simulation with a full environmental test cell.
(i) If that data prove to the satisfaction of the Administrator that the simulation produces results that correlate sufficiently with the environmental test chamber, the Administrator may allow the continued use of the simulation.
(ii) Otherwise, the Administrator will determine that the simulation fails to meet adequate correlation levels with full environmental testing. As a consequence of this finding, all future air conditioning emission testing on the population of vehicles represented by the failing-spot-check test vehicle (which may include past model year configurations) will be conducted using an environment chamber or a different (or corrected) approved simulation procedure.
(iii) For each vehicle that fails a spot check, the Administrator may select up to two additional vehicles to test for the spot check that do not count against the five vehicle limit of paragraph (a) of this section.
(e) EPA will monitor the aggregate results of spot check testing and full environmental test cells. If EPA determines, based on such aggregate results, that any simulation (other than the AC1 and AC2 procedures described in paragraphs (b) and (c) of this section for the 2000, 2001, and 2002 model years) is producing test results consistently below those from a full environmental test cell, EPA may review its approval of the simulation.

(a) Vehicles are subject to cold temperature testing requirements as described in subpart S of this part and 40 CFR part 600.
(b) Migration to 40 CFR parts 1065 and 1066. This subpart transitions to rely on the test procedure specifications in 40 CFR parts 1065 and 1066 as follows:
(1) Through model year 2021, manufacturers may use the test procedures specified in paragraph (c) or (d) of this section or, using good engineering judgement, elements of both. For any EPA testing before model year 2022, EPA will use the manufacturer's selected procedures for applying acceptable speed-tolerance criteria. For any other parameters, EPA may conduct testing using either of the specified procedures. As allowed under this part, manufacturers may use carryover data from previous model years to demonstrate compliance with emission standards, without regard to the provisions of this section.
(2) For vehicles certified before model year 2022 to any of the Tier 3 emission standards specified in subpart S of this part, manufacturers must determine overall driver accuracy based on driven cycle energy as described in 40 CFR 1066.425(j).
(c) Interim procedures. Through model year 2021, manufacturers may certify vehicles based on data collected according to previously published cold temperature and intermediate temperature testing procedures.
(d) Long-term procedures. Starting in model year 2022, perform testing to measure CO and NMHC emissions and determine fuel economy as described in 40 CFR part 1066; see especially 40 CFR 1066.710. We may approve the use of previously published cold temperature and intermediate temperature testing procedures for later model years as an alternative procedure under 40 CFR 1066.10(c). Perform intermediate temperature testing as follows:
(1) For testing during ambient temperatures of less than 50 °F (10 °C), perform testing as described in 40 CFR part 1066, subpart H.
(2) For testing at temperatures of 50 °F (10 °C) or higher, perform FTP testing as described in 40 CFR part 1066.
(e) Section 86.213 describes special provisions related to test fuel specifications.
§ 86.213   Fuel specifications.
(a) Gasoline. Use a gasoline test fuel with ethanol (low-level blend only) or without ethanol as follows:
(1) You must certify using service accumulation fuel and E10 test fuel as specified in § 86.113 for any vehicles required to use a low-level ethanol-gasoline blend test fuel for measuring exhaust emissions. You may use this test fuel any time earlier than we specify.
(2) You may use the test fuel specified in this paragraph (a)(2) for vehicles that are not yet subject to exhaust testing with an ethanol-blend test fuel under § 86.113. Manufacturers may certify based on this fuel using carryover data until testing with the ethanol-blend test fuel is required. The following specifications apply for gasoline test fuel without ethanol:
Table 1 of § 86.213—Cold Temperature Test Fuel Specifications for Gasoline Without Ethanol
1 Incorporated by reference, see § 86.1.
2 Octane specifications are optional for manufacturer testing. The premium fuel specifications apply for vehicles designed to use high-octane premium fuel.
3 Sulfur concentration will not exceed 0.0045 weight percent for EPA testing.
4 ASTM D6550 prescribes measurement of olefin concentration in mass %. Multiply this result by 0.857 and round to the first decimal place to determine the olefin concentration in volume %.
(3) Manufacturers may use the E0 gasoline test fuel specified in § 86.113 for certification instead of the fuel specified in paragraph (a)(2) of this section, as long as the change in test fuel does not cause cold temperature NMHC, CO, or CO 2 emissions to decrease; manufacturers must keep records documenting these emission effects and make them available to EPA upon request.
(4) We may approve alternate fuel specifications that are substantially equivalent to those in paragraph (a)(2) of this section for a manufacturer's testing.

§ 86.406-78   Introduction, structure of subpart, further information.
(a) This subpart contains general provisions regulating the emission of air pollution from new motorcycles. Test procedures are found in subpart F.
(b) Several discrete concepts are addressed:
(1) Requirements. Sections 86.407 to 86.415.
(2) Application for certification. Sections 86.416 and 86.417.
(3) Test fleet selection. Sections 86.418 to 86.423.
(4) Service accumulation, testing, maintenance, certification. Sections 86.424 to 86.439.
(5) Administrative provisions. Sections 86.440 to 86.444.
(c) The certification procedure to be followed depends upon the manufacturer's projected sales.
(1) New motorcycles, produced by a manufacturer whose projected U.S. sales of motorcycles is 10,000 or more units (for the model year in which certification is sought) shall demonstrate compliance with all general standards and all specific emission requirements before they can be sold in the United States. The manufacturer is required to submit an application with sales data, product information, required maintenance, testing and service accumulation procedures. The Administrator will select vehicle(s) which will represent the manufacturer's product line. The manufacturer is required to construct these vehicles to be representative of actual production. Service is accumulated and emission tests performed with data submitted to the Administrator. The Administrator may run his own tests to confirm the manufacturer's results. The Administrator will review the data and either grant or deny certification. If the manufacturer wishes to make changes to a certified vehicle, or to produce a new vehicle, the Administrator must be notified. The Administrator may require testing to demonstrate continued compliance with emission standards. Each vehicle must be labeled with tune up specifications and the purchaser must be supplied with maintenance instructions. Also, information on production vehicles must be supplied to the Administrator.
(2) New motorcycles produced by a manufacturer whose projected U.S. sales of motorcycles is less than 10,000 units (for the model year in which certification is sought) shall meet both the general standards and specific emission requirements described in §§ 86.401 through 86.417, § 86.425, § 86.437, and §§ 86.440 through 86.444 of this subpart before they can be sold in the United States. The manufacturer is required to submit an application containing a statement that his vehicles conform to the applicable emission standards. The manufacturer is required to retain in his records, but not submit with the application, valid emission test data which support his statement. The Administrator will review the application and either grant or deny certification. Each vehicle must be labeled with tune up specifications and the purchaser must be supplied with maintenance instructions. Also, information on production vehicles must be supplied to the Administrator.
(d) Manufacturers who are considering an application should contact: Director, Vehicle Programs and Compliance Division, Environmental Protection Agency, 2565 Plymouth Rd., Ann Arbor, Michigan 48105 and state whether he/she plans to certify for total sales of greater than or less than 10,000 vehicles for the applicable model year.
§ 86.407-78   Certificate of conformity required.
(a) General requirement. Every new motorcycle manufactured for sale, sold, offered for sale, introduced or delivered for introduction into commerce, or imported into the United States which is subject to any of the standards prescribed in this subpart is required to be covered by a certificate of conformity issued pursuant to this subpart, except as specified in paragraph (b) of this section, or otherwise exempted from this requirement.
(b) Interim personal use exemption. An individual may manufacture one motorcycle for personal use without a certificate of conformity, subject to the following provisions:
(1) The motorcycle may not be manufactured from a certified motorcycle. The motorcycle may not be manufactured from a partially complete motorcycle that is equivalent to a certified motorcycle, unless the emission controls are included in the final product. The motorcycle must be manufactured primarily from unassembled components, but may incorporate some preassembled components. For example, fully preassembled transmissions may be used.
(2) The motorcycle may not be sold within five years of the date of final assembly.
(3) No individual may manufacture more than one motorcycle during his or her lifetime under this exemption. This restriction applies with respect to the person who purchases the components and/or uses the motorcycle, rather than to the person(s) who actually assemble(s) the motorcycle.
(4) This exemption may not be used to circumvent the requirements of paragraph (a) of this section or the requirements of the Clean Air Act. For example, this exemption would not cover a case in which an entity purchases a kit, assembles the kit, and then sells it to another party; this would be considered to be the sale of the complete motorcycle.
(c) Interim display exemptions. Uncertified custom motorcycles that are used solely for display purposes are exempt from the standards provided they conform to the requirements of this paragraph (c). Unless a certificate of conformity has been received for such motorcycles, they may not be operated on the public streets or highways except for that operation incident and necessary to the display purpose.
(1) No request is necessary for display motorcycles that will not be sold or leased.
(2) The following requirements apply for exempting display motorcycles that will be sold or leased:
(i) Manufacturers planning to sell motorcycles for display must notify EPA of their intent to do so before they sell any exempted motorcycles. They must also maintain sales records of exempted motorcycles for at least three years and make them available to EPA upon request.
(ii) No manufacturer may sell or lease more than 24 exempted display motorcycles in any single calendar year.
(iii) Anyone selling or leasing a motorcycle exempt under this paragraph (c) must ensure that the buyer or lessee agrees to comply with the display exemption terms in the regulations.
(3) Each motorcycle exempt under this paragraph (c) must include a label that identifies the manufacturer and includes the following statement: THIS MOTORCYCLE IS EXEMPT FROM EPA EMISSION REQUIREMENTS. ITS USE ON PUBLIC ROADS IS LIMITED PURSUANT TO 40 CFR 86.407-78(c). EPA may allow manufacturers to locate the label in a location where it is obscured or hidden by a readily removable component. For example, EPA may allow the label to be located under the seat.
(4) As described in 40 CFR part 1051, motorcycles that are not considered to be motor vehicles according to 40 CFR 85.1703(a) may be exempt under this paragraph (c) from the standards and requirements of 40 CFR part 1051. Such motorcycles shall be combined with the manufacturer's highway motorcycles with respect to the sales restriction described in paragraph (c)(2)(ii) of this section.
(5) This exemption may not be used to circumvent the requirements of paragraph (a) of this section or the requirements of the Clean Air Act.
§ 86.408-78   General standards; increase in emissions; unsafe conditions.
(a) Any system installed on or incorporated in a new motorcycle to enable such vehicle to conform to standards imposed by this subpart:
(1) Shall not in its operation or function cause the emission into the ambient air of any noxious or toxic substance that would not be emitted in the operation of such vehicle without such system, except as specifically permitted by regulation; and
(2) Shall not in its operation, function, or malfunction result in any unsafe condition endangering the motorcycle, its rider(s), or persons or property in close proximity to the vehicle.
(b) Every manufacturer of new motorcycles subject to any of the standards imposed by this subpart shall, prior to taking any of the actions specified in section 203(a)(1) of the Act, test or cause to be tested motorcycles in accordance with good engineering practice to ascertain that such test vehicles will meet the requirements of this section for the useful life of the vehicle.
(c) If a new motorcycle is designed to require manual adjustment to compensate for changing altitude, the manufacturer must include the appropriate instructions in the application for certification. EPA will review the instructions to ensure that properly adjusted motorcycles will meet emission standards at both low altitude and high altitude.
(d) An action to install parts, modify engines, or perform other adjustments to compensate for changing altitude is not prohibited under 42 U.S.C. 7522 as long as it is done consistent with the manufacturer's instructions.
§ 86.409-78   Defeat devices, prohibition.
(a) No motorcycle shall be equipped with a defeat device.
(b) Defeat device means any element of design which:
(1) Senses temperature, vehicle speed, engine RPM, transmission gear, manifold vacuum, or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control system and
(2) Reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal urban vehicle operation and use, unless
(i) Such conditions are substantially included in the Federal emission test procedure, or
(ii) The need for the device is justified in terms of protecting the vehicle against damage or accident, or
(iii) The device does not go beyond the requirements of engine starting or warm-up.
§ 86.410-90   Emission standards for 1990 and later model year motorcycles.
(a)(1) Exhaust emissions from 1990 and later model year gasoline-fueled, natural gas-fueled and liquefied petroleum gas-fueled motorcycles shall not exceed (compliance with these standards is optional prior to the 1997 model year for natural gas-fueled and liquefied petroleum gas-fueled motorcycles):
(i) Hydrocarbons. 5.0 grams per vehicle kilometer.
(ii) Carbon monoxide. 12 grams per vehicle kilometer.
(2) Exhaust emissions from 1990 and later model year methanol-fueled motorcycles shall not exceed:
(i) Total hydrocarbon equivalent. 5.0 grams per vehicle kilometer.

(ii) Class I motorcycles with engine displacement 50 cc or higher comprise the Class I-B subclass.
(2) Class II—170 to 279 cc (10.4 to 17.1 cu. in.).
(3) Class III—280 cc and over (17.1 cu. in. and over).
(c) At the manufacturer's option, a vehicle described in an application for certification may be placed in a higher class (larger displacement). All procedures for the higher class must then be complied with and compliance with emission standards will be determined on the basis of engine displacement.
§ 86.420-78   Engine families.
(a) The vehicles covered in the application will be divided into groupings whose engines are expected to have similar emission characteristics throughout their useful life. Each group of engines with similar emission characteristics shall be defined as a separate engine family.
(b) Reciprocating families. To be classed in the same engine family, reciprocating engines must be identical in all of the following applicable respects:

(11) The prechamber characteristics.
(e) At the manufacturer's option, rotary combustion cycle engines identical in all the respects listed in paragraph (d) of this section, may be further divided into different engine families if the Administrator determines that they may be expected to have different emission characteristics. This determination will be based upon a consideration of features, such as:
(1) The width of the rotor housing.
(2) The type and location of intake port (side, peripheral, combination, etc.).
(3) The number of spark plugs per rotor.
(4) The fuel system.
(5) The exhaust system.
(f) Where engines are of a type which cannot be divided into engine families based upon the criteria listed in paragraphs (b) and (d) of this section, the Administrator will establish families of those engines based upon the features most related to their emission characteristics.
§ 86.421-78   Test fleet.
(a) A test vehicle will be selected by the Administrator to represent each engine-displacement-system combination. The configuration (engine calibration, transmission, drive ratio, mass, options, etc.) in the manufacturer's application which the Administrator believes has the greatest probability of exceeding the standards will be selected.
(b) At the manufacturer's option, the Administrator will only select one vehicle to represent each engine family where the total projected annual sales for that family are less than 5,000 vehicles.
(c) A manufacturer may elect to operate and test additional vehicles which are identical to those selected by the Administrator. Written notice of a commitment to operate and test additional vehicles shall be given to the Administrator prior to the start of testing and not later than 30 days following notification of the test fleet selection. The results of tests performed by the manufacturer will be combined to determine deterioration factors. Each vehicle must meet applicable standards when tested by the Administrator and when those results are projected to the useful life.
(d) In lieu of testing a test vehicle and submitting data therefore, a manufacturer may, with the prior written approval of the Administrator, submit exhaust emission data on a similar vehicle for which certification has previously been obtained or for which all applicable data has previously been submitted.

§ 86.427-78   Emission tests.
(a)(1) Each test vehicle shall be driven with all emission control systems installed and operating for the following total test distances, or for such lesser distances as the Administrator may agree to as meeting the objectives of this procedure. (See § 86.419 for class explanation.)
Table 1 to § 86.427-78—Test Specifications by Displacement Class
(2) A zero kilometer emission test may be performed prior to the beginning of service accumulation.
(b) All vehicles shall undergo at least four emission tests; one at the minimum test distance, one before and one after periodic maintenance, and one at the total test distance. If no maintenance is scheduled, then at least two tests will be performed, at equal intervals, between the minimum and total test distances. Additional tests may be performed; such tests must be at equal intervals and approved by the Administrator prior to starting service accumulation.
(c) Where the Administrator agrees to a lesser distance for service accumulation, he may modify the maintenance provisions of this subpart.
(d) All tests required by this subpart must be conducted at an accumulated distance within 250 kilometers (155 mi) of the nominal distance at each test point.
(e)(1) If a manufacturer conducts multiple tests at any test point at which the data are intended to be used in the calculation of the deterioration factor, the number of tests must be the same at each point and may not exceed three valid tests unless the manufacturer chooses to average the test results.
(2) If the manufacturer chooses to average the test results at a test point, he may conduct more tests than the minimum number of tests conducted at any other test point.
The results of the multiple tests shall be averaged to create a single value which is the test point value used in the deterioration factor calculation specified in § 86.432-78.
(3) When using this option to generate data for a particular test point, the manufacturer must include in the average all valid test data generated at that test point.
(4) The manufacturer shall follow the same procedure for all exhaust pollutants.
(5) The test results obtained from the emission tests performed before and after maintenance affecting emissions shall not be averaged.

The Administrator may specify that he will conduct such testing at the manufacturer's facility, in which case instrumentation and equipment specified by the Administrator shall be made available by the manufacturer for test operations. Any testing conducted at a manufacturer's facility pursuant to this paragraph shall be scheduled by the manufacturer as promptly as possible.
(g) Whenever the Administrator conducts a test on a test vehicle, the results of that test, unless subsequently invalidated by the Administrator, shall comprise the data for the vehicle at that prescribed test point and the manufacturer's data for that prescribed test point shall not be used in determining compliance with emission standards.
§ 86.428-80   Maintenance, scheduled; test vehicles.
(a) Periodic maintenance on the engine, emission control system, and fuel system of test vehicles shall be scheduled for performance at the same distance intervals that will be specified in the manufacturer's maintenance instructions furnished to the ultimate purchaser. Such maintenance shall be performed only under the following provisions.
(b) Periodic major engine tune-ups to the manufacturer's specifications may be performed no more frequently than as follows nor may any tune-up be performed within 1000 km prior to the official test.
(c) A scheduled major engine tune-up shall be restricted to items listed below and shall be conducted in a manner consistent with service instructions and specifications provided by the manufacturer for use by customer service personnel. The following items may be inspected, replaced, cleaned, adjusted, and/or serviced as required: (1) Breaker points, timing, (2) idle speed and idle air/fuel mixture, (3) valve lash, (4) engine bolt torque, and (5) spark plugs.
(d) The Administrator will specify the ignition timing, idle air fuel mixture and other fuel system adjustments to be used at each tune-up. The settings selected will be those the Administrator deems appropriate within the physically available range.
(e) Periodic change of engine and transmission oil, and change or service of oil, air, and fuel filters will be allowed at the same distance intervals that will be specified in the manufacturer's maintenance instructions.
(f) Requests for authorization of periodic maintenance of emission control related components not specifically authorized to be maintained by this section, and for anticipated maintenance (see § 86.428), must be made prior to the beginning of distance accumulation. The Administrator will approve the performance of such maintenance if the manufacturer makes a satisfactory showing that the maintenance will be performed on vehicles in use and that the maintenance is reasonable and necessary.
(1) The EGR system may be serviced a maximum of two times during the durability service accumulation if failure of the EGR system activates an audible and/or visual signal approved by the Administrator which alerts the vehicle operator to the need for EGR system maintenance, or if the need for periodic maintenance of the EGR system is overtly signalled to the vehicle operator by an appropriate means, e.g., an indicator light or significantly reduced driveability performance.
(2) The catalytic converter may be serviced only once during the durability service accumulation if failure of the catalytic converter activates an audible and/or visual signal approved by the Administrator which alerts the vehicle operator to the need for catalytic converter maintenance, or if the need for periodic maintenance of the catalytic converter is overtly signalled to the vehicle operator by an appropriate means, e.g., an indicator light or significantly reduced driveability performance.
(g) Certain engine components may require maintenance which, by its nature, cannot be scheduled for periodic intervals, but which the manufacturer believes will be necessary. For example, piston and cylinder replacement caused by piston seizure which results in the vehicle being inoperative; or in the case of two-stroke engines, decarbonization, the need for which is signalled to the vehicle operator by significantly reduce driveability performance. Such maintenance is designated anticipated maintenance. Anticipated maintenance must be identified by the manufacturer and approved as being appropriate by the Administrator prior to the start of service accumulation. The approximate distance at which the need for anticipated maintenance may arise must be specified in the application for certification.
(h) Complete emission tests (see subpart F) are required, unless waived by the Administrator, before and after any vehicle maintenance which may reasonably be expected to affect emissions.
§ 86.429-78   Maintenance, unscheduled; test vehicles.
(a) Any unscheduled engine, emission control system, or fuel system adjustment, repair, removal, disassembly, cleaning, or replacement on vehicles shall be performed only with the advance approval of the Administrator.
(1) In the case of unscheduled maintenance, such approval will be given if the Administrator:
(i) Has made a preliminary determination that part failure or system malfunction, or the repair of such failure or malfunction, does not render the vehicle unrepresentative of vehicles in use, and does not require direct access to the combustion chamber, except for spark plug, fuel injection component, or removable prechamber removal or replacement; and
(ii) Has made a determination that the need for maintenance or repairs is indicated by an overt indication of malfunction such as persistent misfire, vehicle stall, overheating, fluid leakage, loss of oil pressure, or charge indicator warning.
(2) Emission measurements may not be used as a means of determining the need for unscheduled maintenance under paragraph (a)(1)(i) of this section.
(b) Repairs to vehicle components of test vehicles, other than the engine, emission control system, or fuel system, shall be performed only as a result of part failure, vehicle system malfunction, or with the advance approval of the Administrator.
(c) The Administrator shall be given the opportunity to verify the extent of an overt indication of part failure and/or vehicle malfunction (e.g., misfire, stall), or an activation of an audible and/or visual signal, prior to the performance of any maintenance to which such overt indication or signal is relevant under the provisions of this section.
(d) Equipment, instruments, or tools may not be used to identify malfunctioning, maladjusted, or defective engine components unless the same or equivalent equipment, instruments, or tools will be available at dealerships and other service outlets and
(1) Are used in conjunction with scheduled maintenance on such components, and
(2) Are used subsequent to the identification of a vehicle or engine malfunction, as provided in paragraph (a)(1) of this section for durability or emission data vehicles, or
(3) Unless specifically authorized by the Administrator.
(e) If the Administrator determines that part failure or system malfunction occurrence and/or repair rendered the vehicle unrepresentative of vehicles in use, the vehicle shall not be used as a test vehicle.
(f) Complete emission tests are required, unless waived by the Administrator, before and after any vehicle maintenance which may reasonably be expected to affect emissions.
§ 86.430-78   Vehicle failure.
Any test vehicle which incurs major mechanical failure necessitating disassembly of the engine shall not be used as a test vehicle. This prohibition does not apply to failures occurring after the completion of all required tests at the total test distance.
§ 86.431-78   Data submission.
(a) Data from all tests (including voided tests) performed by a manufacturer with total projected sales in excess of 10,000 vehicles shall be included in the application.
(b) The manufacturer shall furnish to the Administrator explanation for voiding any test. The Administrator will determine if voiding the test was appropriate based upon the explanation given by the manufacturer. If the Administrator determines that voiding the test was not appropriate, the Administrator may require that the data from that test be used in the calculation of the deterioration factor for emissions.

Use the analytical equipment and procedures specified in 40 CFR part 1065 as needed to measure N 2 O and CH 4 . Report these values in your application for certification. The requirements of this paragraph (e) apply starting with model year 2011 for CO 2 and 2012 for CH 4 . The requirements of this paragraph (e) related to N 2 O emissions apply for engine families that depend on NO X aftertreatment to meet emission standards starting with model year 2013. Small-volume manufacturers (as defined in § 86.410-2006(e)) may omit measurement of N 2 O and CH 4 ; other manufacturers may provide appropriate data and/or information and omit measurement of N 2 O and CH 4 as described in 40 CFR 1065.5. Use the same measurement methods as for your other results to report a single value for CO 2 , N 2 O, and CH 4 . Round the final values as follows:
(1) Round CO 2 to the nearest 1 g/km.
(2) Round N 2 O to the nearest 0.001 g/km.
(3) Round CH 4 to the nearest 0.001 g/km.
§ 86.432-78   Deterioration factor.
(a) Deterioration factors shall be developed for each test vehicle from the emission test results. A separate factor shall be developed for each pollutant. The applicable data to be used in calculating these factors are:
(1) The results from all valid tests conducted by the manufacturer or Administrator at scheduled test intervals.
(2) The results from tests conducted before and after scheduled maintenance unless specifically excluded by the Administrator.
(3) The results from tests conducted before and after unscheduled maintenance, if approval of the maintenance by the Administrator was conditioned on the data being used in the deterioration factor calculation.
(b) Emission results which are less than 0.10 g/km shall be considered to be 0.10 g/km for purposes of this section.
(c) Test results for each pollutant shall be plotted as a function of the service accumulated at the start of the emission test, rounded to the nearest kilometre. These results shall be correlated to a straight line, fit by the method of least squares.
(d) An exhaust emission deterioration factor will be calculated by dividing the predicted emissions at the useful life distance by the predicted emissions at the total test distance. Predicted emissions are obtained from the correlation developed in paragraph (c) of this section.
(e) Deterioration factors computed to be less than 1.000 shall be 1.000.
(f)(1) The manufacturer has the option of applying an outlier test point procedure to completed durability data within its certification testing program for a given model year.
(2) The outlier procedure will be specified by the Administrator.
(3) For any pollutant, durability-data test points that are identified as outliers shall not be included in the determination of deterioration factors if the manufacturer has elected this option.
(4) The manufacturer shall specify to the Administrator, before the certification of the first engine family for that model year, if it intends to use the outlier procedure.
(5) The manufacturer may not change procedures after the first engine family of the model year is certified.
(6) Where the manufacturer chooses to apply the outlier procedure to a data set containing data which were averaged under § 86.427-78(e), the outlier procedure shall be completed before averaging the data.
§ 86.434-78   Testing by the Administrator.
(a) At the conclusion of service accumulation, and after emission tests for deterioration, the Administrator may require confirmatory testing. The Administrator will designate where such testing shall be performed.
(b) The manufacturer may request a retest. The results of the retest will be used to determine compliance.
(c) If the emission results exceed the standard, certification will be denied.
§ 86.435-78   Extrapolated emission values.
(a) If the deterioration factor lines are below the standards between the minimum test distance and the useful life, or if all points used to generate the lines are below the standards, predicted useful life emissions shall be calculated. If not, the manufacturers may elect to withdraw the vehicle or accumulate additional service.
(b) The emission test results of each pollutant obtained from the half life test will be multiplied by the appropriate deterioration factors to determine useful life emissions.
(1) If the useful life emissions are at or below the standards, certification will be granted.
(2) If any of the useful life emissions exceed the emission standards, the vehicle must (if not withdrawn) accumulate distance to the useful life.
§ 86.436-78   Additional service accumulation.
(a) Additional service up to the useful life will be accumulated under the same conditions as the initial service accumulation.
(b) New deterioration lines will be generated using all applicable test points up to the useful life. The same procedures for determining the original deterioration lines will be used.
(c) [Reserved]
(d) To qualify for certification:
(1) The full life emission test results must be at or below the standards in this subpart; and
(2) The deterioration line must be below the standard at the minimum test distance and the useful life, or all points used to generate the line, must be at or below the standard.
(e) If the vehicle is unable to complete the total distance due to engine mechanical failure, certification will be granted if:
(1) The mechanical failure was anticipated, § 86.428, and
(2) A new deterioration line calculated using the procedure described in § 86.436-78(b) is below the standard at the minimum test distance and at the useful life, and,
(3) The results of the half life emission tests, when adjusted by the new deterioration factors, are below the standards.

§ 86.441-78   Right of entry.
(a) Any manufacturer who has applied for certification of a new motorcycle subject to certification tests under this subpart shall admit or cause to be admitted any EPA Enforcement Officer during operating hours on presentation of any credentials to any of the following:
(1) Any facility where any such tests or any procedures or activities connected with such tests are or were performed.
(2) Any facility where any new motorcycle which is being, was or is to be tested is present.
(3) Any facility where any construction process or assembly process used in the modification or build-up of such a vehicle into a certification vehicle is taking place or has taken place.
(4) Any facility where any record or other document relating to any of the above is located.
(b) Upon admission to any facility referred to in paragraph (c)(1) of this section, any EPA Enforcement Officer shall be allowed:
(1) To inspect and monitor any part or aspect of such procedures, activities, and testing facilities, including, but not limited to, monitoring vehicle preconditioning, emissions tests and service accumulation, maintenance, and vehicle soak and storage procedures; and to verify correlation or calibration of test equipment;
(2) To inspect and make copies of any such records, designs, or other documents; and
(3) To inspect and/or photograph any part or aspect of any such certification vehicle and any components to be used in the construction thereof.
(c) In order to allow the Administrator to determine whether or not production motorcycles conform in all material respects to the design specifications which applied to those vehicles described in the application for certification for which a certificate of conformity has been issued and to standards prescribed under section 202 of the Act, any manufacturer shall admit any EPA Enforcement Officer on presentation of credentials to both:
(1) Any facility where any document design, or procedure relating to the translation of the design and construction of engines and emission related components described in the application for certification or used for certification testing into production vehicles is located or carried on; and
(2) Any facility where any motorcycles to be introduced into commerce are manufactured or assembled.
(d) On admission to any such facility referred to in paragraph (c)(3) of this section, any EPA Enforcement Officer shall be allowed:
(1) To inspect and monitor any aspects of such manufacture or assembly and other procedures;
(2) To inspect and make copies of any such records, documents or designs; and
(3) To inspect and photograph any part or aspect of any such new motorcycles and any component used in the assembly thereof that are reasonably related to the purpose of his entry.
(e) Any EPA Enforcement Officer shall be furnished by those in charge of a facility being inspected with such reasonable assistance as he may request to help him discharge any function listed in this paragraph. Each applicant for or recipient of certification is required to cause those in charge of a facility operated for its benefit to furnish such reasonable assistance without charge to EPA whether or not the applicant controls the facility.
(f) The duty to admit or cause to be admitted any EPA Enforcement Officer applies whether or not the applicant owns or controls the facility in question and applies both to domestic and to foreign manufacturers and facilities. EPA will not attempt to make any inspections which it has been informed that local law forbids. However, if local law makes it impossible to do what is necessary to insure the accuracy of data generated at a facility, no informed judgment that a vehicle or engine is certifiable or is covered by a certificate can properly be based on that data. It is the responsibility of the manufacturer to locate its testing and manufacturing facilities in jurisdictions where this situation will not arise.
(g) For purposes of this section:
(1) Presentation of credentials shall mean display of the document designating a person as an EPA Enforcement Officer.
(2) Where vehicle, component, or engine storage areas or facilities are concerned, operating hours shall mean all times during which personnel other than custodial personnel are at work in the vicinity of the area or facility and have access to it.
(3) Where facilities or areas other than those covered by paragraph (g)(2) of this section are concerned, operating hours shall mean all times during which an assembly line is in operation or all times during which testing, maintenance, service accumulation, production or compilation of records, or any other procedure or activity related to certification testing, to translation of designs from the test stage to the production stage, or to vehicle manufacture or assembly is being carried out in a facility.
(4) Reasonable assistance includes, but is not limited to, clerical, copying, interpretation and translation services, the making available on request of personnel of the facility being inspected during their working hours to inform the EPA Enforcement Officer of how the facility operates and to answer his questions, and the performance on request of emissions tests on any vehicle which is being, has been, or will be used for certification testing. Such tests shall be nondestructive, but may require appropriate service accumulation. A manufacturer may be compelled to cause the personal appearance of any employee at such a facility before an EPA Enforcement Officer by written request for his appearance, signed by the Assistant Administrator for Enforcement, served on the manufacturer. Any such employee who has been instructed by the manufacturer to appear will be entitled to be accompanied, represented, and advised by counsel. No counsel who accompanies, represents, or advises an employee compelled to appear may accompany, represent, or advise any other person in the investigation.
(5) Any entry without 24 hours prior written or oral notification to the affected manufacturer shall be authorized in writing by the Assistant Administrator for Enforcement.
§ 86.442-78   Denial, revocation, or suspension of certification.
(a) Notwithstanding the fact that any certification vehicle(s) may comply with other provisions of this subpart, the Administrator may withhold or deny the issuance of a certificate of conformity (or suspend or revoke any such certificate which has been issued) with respect to any such vehicle(s) if:
(1) The manufacturer submits false or incomplete information in his application for certification thereof; or
(2) The manufacturer renders inaccurate or invalid any test data which he submits pertaining thereto or otherwise circumvents the intent of the Act or of this subpart with respect to such vehicle; or
(3) Any EPA Enforcement Officer is denied access on the terms specified in § 86.441 to any facility or portion thereof which contains any of the following:
(i) The vehicle, or
(ii) Any components used or considered for use in its modification or build-up into a certification vehicle, or
(iii) Any production vehicle which is or will be claimed by the manufacturer to be covered by the certificate, or
(iv) Any step in the construction of a vehicle described in paragraph (c) of this section, or
(v) Any records, documents, reports, or histories required by this part to be kept concerning any of the above.
(4) Any EPA Enforcement Officer is denied “reasonable assistance” (as defined in § 86.444) in examining any of the items listed in paragraph (a)(1)(iii) of this section.
(b) The sanctions of withholding, denying, revoking, or suspending of a certificate may be imposed for the reasons in paragraph (a) of this section only when the infraction is substantial.
(c) In any case in which a manufacturer knowingly submits false or inaccurate information, or knowingly renders inaccurate or invalid any test data, or commits any fraudulent acts and such acts contribute substantially to the Administrator's decision to issue a certificate of conformity, the Administrator may deem such certificate void ab initio.
(d) In any case in which certification of a vehicle is proposed to be withheld, denied, revoked, or suspended under paragraph (a) (3) or (4) of this section, and in which the Administrator has presented to the manufacturer involved reasonable evidence that a violation of § 86.441 in fact occurred, the manufacturer, if the wishes to contend that, even though the violation occurred, the vehicle in question was not involved in the violation to a degree that would warrant withholding, denial, revocation, or suspension of certification under either paragraph (a) (3) or (4) of this section, shall have the burden of establishing that contention to the satisfaction of the Administrator.
(e) Any revocation or suspension of certification under paragraph (a) of this section shall:
(1) Be made only after the manufacturer concerned has been offered an opportunity for a hearing conducted in accordance with § 86.444 hereof.
(2) Extend no further than to forbid the introduction into commerce of vehicles previously covered by the certification which are still in the hands of the manufacturer, except in cases of such fraud or other misconduct as makes the certification invalid ab initio.
(f) The manufacturer may request in the form and manner specified in § 86.443 that any determination made by the Administrator under paragraph (a) of this section to withhold or deny certification be reviewed in a hearing conducted in accordance with § 86.444. If the Administrator finds, after a review of the request and supporting data, that the request raises a substantial factual issue, he will grant the request with respect to such issue.
§ 86.443-78   Request for hearing.
The manufacturer may request a hearing on the Administrator's determination as described in 40 CFR part 1068, subpart G.
§ 86.444-78   Hearings on certification.
If a manufacturer's request for a hearing is approved, EPA will follow the hearing procedures specified in 40 CFR part 1068, subpart G.

§ 86.447-2006   What provisions apply to motorcycle engines below 50 cc that are certified under the Small SI program or the Recreational-vehicle program?
(a) General provisions. If you are an engine manufacturer, this section allows you to introduce into commerce a new highway motorcycle (that is, a motorcycle that is a motor vehicle) if it has an engine below 50 cc that is already certified to the requirements that apply to engines or vehicles under 40 CFR part 90 or 1051 for the appropriate model year. If you comply with all the provisions of this section, we consider the certificate issued under 40 CFR part 90 or 1051 for each engine or vehicle to also be a valid certificate of conformity under this part 86 for its model year, without a separate application for certification under the requirements of this part 86. See § 86.448-2006 for similar provisions that apply to vehicles that are certified to chassis-based standards under 40 CFR part 1051.
(b) Vehicle-manufacturer provisions. If you are not an engine manufacturer, you may produce highway motorcycles using nonroad engines below 50 cc under this section as long as you meet all the requirements and conditions specified in paragraph (d) of this section. If you modify the nonroad engine in any of the ways described in paragraph (d)(2) of this section for installation in a highway motorcycle, we will consider you a manufacturer of a new highway motorcycle. Such engine modifications prevent you from using the provisions of this section.
(c) Liability. Engines for which you meet the requirements of this section, and vehicles containing these engines, are exempt from all the requirements and prohibitions of this part, except for those specified in this section. Engines and vehicles exempted under this section must meet all the applicable requirements from 40 CFR part 90 or 1051. This applies to engine manufacturers, vehicle manufacturers who use these engines, and all other persons as if these engines were used in recreational vehicles or other nonroad applications. The prohibited acts of 42 U.S.C. 7522 apply to these new highway motorcycles; however, we consider the certificate issued under 40 CFR part 90 or 1051 for each engine to also be a valid certificate of conformity under this part 86 for its model year. If we make a determination that these engines do not conform to the regulations during their useful life, we may require you to recall them under 40 CFR part 86, 90, or 1068.
(d) Specific requirements. If you are an engine or vehicle manufacturer and meet all the following criteria and requirements regarding your new engine or vehicle, the highway motorcycle is eligible for an exemption under this section:
(1) Your engine must be below 50 cc and must be covered by a valid certificate of conformity for Class II engines issued under 40 CFR part 90 or for recreational vehicles under 40 CFR part 1051.
(2) You must not make any changes to the certified engine that could reasonably be expected to increase its exhaust emissions for any pollutant, or its evaporative emissions, if applicable. For example, if you make any of the following changes to one of these engines, you do not qualify for this exemption:
(i) Change any fuel system or evaporative system parameters from the certified configuration.
(ii) Change, remove, or fail to properly install any other component, element of design, or calibration specified in the engine manufacturer's application for certification. This includes aftertreatment devices and all related components.
(iii) Modify or design the engine cooling system so that temperatures or heat rejection rates are outside the original engine manufacturer's specified ranges.
(3) You must show that fewer than 50 percent of the engine family's total sales in the United States are used in highway motorcycles. This includes engines used in any application, without regard to which company manufactures the vehicle or equipment. In addition, if you manufacture highway motorcycles, you must show that fewer than 50 percent of the engine family's total sales in the United States are highway motorcycles. Show that you meet the engine-sales criterion as follows:
(i) If you are the original manufacturer of the engine, base this showing on your sales information.
(ii) In all other cases, you must get the original manufacturer of the engine to confirm the engine sales volumes based on its sales information.
(4) You must ensure that the engine has the label we require under 40 CFR part 90 or 1051.
(5) You must add a permanent supplemental label to the engine in a position where it will remain clearly visible after installation in the vehicle. In the supplemental label, do the following:
(i) Include the heading: “HIGHWAY MOTORCYCLE ENGINE EMISSION CONTROL INFORMATION”.
(ii) Include your full corporate name and trademark. You may instead include the full corporate name and trademark of another company you choose to designate.
(iii) State: “THIS ENGINE WAS ADAPTED FOR HIGHWAY USE WITHOUT AFFECTING ITS EMISSION CONTROLS.”.
(iv) State the date you finished installation (month and year), if applicable.
(6) Send the Designated Compliance Officer a signed letter by the end of each calendar year (or less often if we tell you) with all the following information:
(i) Identify your full corporate name, address, and telephone number.
(ii) List the engine or vehicle models you expect to produce under this exemption in the coming year.
(iii) State: “We produce each listed [engine or vehicle] model for without making any changes that could increase its certified emission levels, as described in 40 CFR 86.447-2006.”.
(e) Failure to comply. If your highway motorcycles do not meet the criteria listed in paragraph (d) of this section, they will be subject to the standards, requirements, and prohibitions of this part 86 and the certificate issued under 40 CFR part 90 or 1051 will not be deemed to also be a certificate issued under this part 86. Introducing these engines into commerce without a valid exemption or certificate of conformity under this part violates the prohibitions in 40 CFR part 85.
(f) Data submission. We may require you to send us emission test data on any applicable nonroad duty cycles.
(g) Participation in averaging, banking and trading. Engines or vehicles adapted for recreational use under this section may not generate or use emission credits under this part 86. These engines or vehicles may generate credits under the ABT provisions in 40 CFR part 90 or 1051. These engines or vehicles must use emission credits under 40 CFR part 90 or 1051 if they are certified to an FEL that exceeds an applicable standard.
§ 86.448-2006   What provisions apply to vehicles certified under the Recreational-vehicle program?
(a) General provisions. If you are a highway-motorcycle manufacturer, this section allows you to introduce into commerce a new highway motorcycle with an engine below 50 cc if it is already certified to the requirements that apply to recreational vehicles under 40 CFR parts 1051. A highway motorcycle is a motorcycle that is a motor vehicle. If you comply with all of the provisions of this section, we consider the certificate issued under 40 CFR part 1051 for each recreational vehicle to also be a valid certificate of conformity for the motor vehicle under this part 86 for its model year, without a separate application for certification under the requirements of this part 86. See § 86.447-2006 for similar provisions that apply to nonroad engines produced for highway motorcycles.
(b) Nonrecreational-vehicle provisions. If you are not a recreational-vehicle manufacturer, you may produce highway motorcycles from recreational vehicles with engines below 50 cc under this section as long as you meet all the requirements and conditions specified in paragraph (d) of this section. If you modify the recreational vehicle or its engine in any of the ways described in paragraph (d)(2) of this section for installation in a highway motorcycle, we will consider you a manufacturer of a new highway motorcycle. Such modifications prevent you from using the provisions of this section.
(c) Liability. Vehicles for which you meet the requirements of this section are exempt from all the requirements and prohibitions of this part, except for those specified in this section. Engines and vehicles exempted under this section must meet all the applicable requirements from 40 CFR part 1051. This applies to engine manufacturers, vehicle manufacturers, and all other persons as if the highway motorcycles were recreational vehicles. The prohibited acts of 42 U.S.C. 7522 apply to these new highway motorcycles; however, we consider the certificate issued under 40 CFR part 1051 for each recreational vehicle to also be a valid certificate of conformity for the highway motorcycle under this part 86 for its model year. If we make a determination that these engines or vehicles do not conform to the regulations during their useful life, we may require you to recall them under 40 CFR part 86 or 40 CFR 1068.505.
(d) Specific requirements. If you are a recreational-vehicle manufacturer and meet all the following criteria and requirements regarding your new highway motorcycle and its engine, the highway motorcycle is eligible for an exemption under this section:
(1) Your motorcycle must have an engine below 50 cc and it must be covered by a valid certificate of conformity as a recreational vehicle issued under 40 CFR part 1051.
(2) You must not make any changes to the certified recreational vehicle that we could reasonably expect to increase its exhaust emissions for any pollutant, or its evaporative emissions if it is subject to evaporative-emission standards. For example, if you make any of the following changes, you do not qualify for this exemption:
(i) Change any fuel system parameters from the certified configuration.
(ii) Change, remove, or fail to properly install any other component, element of design, or calibration specified in the vehicle manufacturer's application for certification. This includes aftertreatment devices and all related components.
(iii) Modify or design the engine cooling system so that temperatures or heat rejection rates are outside the original vehicle manufacturer's specified ranges.
(3) You must show that fewer than 50 percent of the engine family's total sales in the United States are used in highway motorcycles. This includes highway and off-highway motorcycles, without regard to which company completes the manufacturing of the highway motorcycle. Show this as follows:
(i) If you are the original manufacturer of the vehicle, base this showing on your sales information.
(ii) In all other cases, you must get the original manufacturer of the vehicle to confirm this based on their sales information.
(4) The highway motorcycle must have the vehicle emission control information we require under 40 CFR part 1051.
(5) You must add a permanent supplemental label to the highway motorcycle in a position where it will remain clearly visible. In the supplemental label, do the following:
(i) Include the heading: “HIGHWAY MOTORCYCLE ENGINE EMISSION CONTROL INFORMATION”.
(ii) Include your full corporate name and trademark. You may instead include the full corporate name and trademark of another company you choose to designate.
(iii) State: “THIS VEHICLE WAS ADAPTED FOR HIGHWAY USE WITHOUT AFFECTING ITS EMISSION CONTROLS.”.
(iv) State the date you finished modifying the vehicle (month and year), if applicable.
(6) Send the Designated Compliance Officer a signed letter by the end of each calendar year (or less often if we tell you) with all the following information:
(i) Identify your full corporate name, address, and telephone number.
(ii) List the highway motorcycle models you expect to produce under this exemption in the coming year.
(iii) State: “We produced each listed highway motorcycle without making any changes that could increase its certified emission levels, as described in 40 CFR 86.448-2006.”.
(e) Failure to comply. If your highway motorcycles do not meet the criteria listed in paragraph (d) of this section, they will be subject to the standards, requirements, and prohibitions of this part 86 and 40 CFR part 85, and the certificate issued under 40 CFR part 1051 will not be deemed to also be a certificate issued under this part 86. Introducing these motorcycles into commerce without a valid exemption or certificate of conformity under this part violates the prohibitions in 40 CFR part 85.
(f) Data submission. We may require you to send us emission test data on the duty cycle for Class I motorcycles.
(g) Participation in averaging, banking and trading. Recreational vehicles adapted for use as highway motorcycles under this section may not generate or use emission credits under this part 86. These engines may generate credits under the ABT provisions in 40 CFR part 1051. These engines must use emission credits under 40 CFR part 1051 if they are certified to an FEL that exceeds an applicable standard.
§ 86.449   Averaging provisions.
(a) This section describes how and when averaging may be used to show compliance with applicable HC + NO X emission standards. Emission credits may not be banked for use in later model years, except as specified in paragraph (j) of this section.
(1) Compliance with the Class I and Class II HC + NO X standards set forth in § 86.410-2006 (f) may be demonstrated using the averaging provisions of this section. To do this you must show that your average emission levels are at or below the applicable standards in § 86.410-2006.
(2) Compliance with the Class III HC + NO X standards set forth in § 86.410-2006 (a)(2) may be demonstrated using the averaging provisions of this section. To do this you must show that your average emission levels are at or below the applicable standards in § 86.410-2006.
(3) Family emission limits (FELs) may not exceed the following caps:
(b) Do not include any exported vehicles in the certification averaging program. Include only motorcycles certified under this subpart and intended for sale in the United States.
(c) To use the averaging program, do the following things:
(1) Certify each vehicle to a family emission limit.
(2) Calculate a preliminary average emission level according to paragraph (d) of this section using projected production volumes for your application for certification.
(3) After the end of your model year, calculate a final average emission level according to paragraph (d) of this section for each averaging set for which you manufacture or import motorcycles.
(d) Calculate your average emission level for each averaging set for each model year according to the following equation and round it to the nearest tenth of a g/km. Use consistent units throughout the calculation. The averaging sets are defined in paragraph (k) of this section.
(1) Calculate the average emission level as:
(2) Use production projections for initial certification, and actual production volumes to determine compliance at the end of the model year.
(e)(1) Maintain and keep five types of properly organized and indexed records for each group and for each emission family:
(i) Model year and EPA emission family.
(ii) FEL.
(iii) Useful life.
(iv) Projected production volume for the model year.
(v) Actual production volume for the model year.
(2) Keep paper records of this information for three years from the due date for the end-of-year report. You may use any additional storage formats or media if you like.
(3) Follow paragraphs (f) through (i) of this section to send us the information you must keep.
(4) We may ask you to keep or send other information necessary to implement this subpart.
(f) Include the following information in your application for certification:
(1) A statement that, to the best of your belief, you will not have a negative credit balance for any motorcycle when all credits are calculated. This means that if you believe that your average emission level will be above the standard (i.e., that you will have a deficit for the model year), you must have banked credits pursuant to paragraph (j) of this section to offset the deficit.
(2) Detailed calculations of projected emission credits (zero, positive, or negative) based on production projections. If you project a credit deficit, state the source of credits needed to offset the credit deficit.
(g) At the end of each model year, send an end-of-year report.
(1) Make sure your report includes the following things:
(i) Calculate in detail your average emission level and any emission credits based on actual production volumes.
(ii) If your average emission level is above the allowable average standard, state the source of credits needed to offset the credit deficit.
(2) Base your production volumes on the point of first retail sale. This point is called the final product-purchase location.
(3) Send end-of-year reports to the Designated Compliance Officer within 120 days of the end of the model year. If you send reports later, EPA may void your certificate ab initio.
(4) If you generate credits for banking pursuant to paragraph (j) of this section and you do not send your end-of-year reports within 120 days after the end of the model year, you may not use the credits until we receive and review your reports. You may not use projected credits pending our review.
(5) You may correct errors discovered in your end-of-year report, including errors in calculating credits according to the following table:
(h) Include in each report a statement certifying the accuracy and authenticity of its contents.
(i) We may void a certificate of conformity for any emission family if you do not keep the records this section requires or give us the information when we ask for it.
(j) You may include Class III motorcycles that you certify with HC + NO X emissions below 0.8 g/km in the following optional early banking program:
(1) To include a Class III motorcycle in the early banking program, assign it an emission rate of 0.8 g/km when calculating your average emission level for compliance with the Tier 1 standards.
(2)(i) Calculate bankable credits from the following equation:
(ii) The value of Y is defined by the model year and emission level, as shown in the following table:
(3) Credits banked under this paragraph (j) may be use for compliance with any 2010 or later model year standards as follows:
(i) If your average emission level is above the average standard, calculate your credit deficit according to the following equation, rounding to the nearest tenth of a gram:
(ii) Credit deficits may be offset using banked credits.
(k) Credits may not be exchanged across averaging sets except as explicitly allowed by this paragraph (k).
(1) There are two averaging sets:
(i) Class I and Class II motorcycles certified to HC + NO X standards.
(ii) Class III motorcycles.
(2) Where a manufacturer's average HC + NO X emission level for Class III motorcycles (as calculated under paragraph (d)(1) of this section) is below the applicable standard, the manufacturer may generate credits that may be used show compliance with HC + NO X standards for Class I and Class II motorcycles during the same model year. Use the following equations to calculate credits and credit deficits for each class or subclass:
(l) Manufacturers participating in the averaging program of this section may modify FELs during the model year as specified in this paragraph (l).
(1) Upon notifying EPA, manufacturers may raise the FEL for an engine family and begin labeling motorcycles with the new FEL.
(2) Manufacturers may ask to lower FELs based on test data of production vehicles showing that the motorcycles in the engine family have emissions below the new FEL. Manufacturers must test the motorcycles according to 40 CFR part 1051, subpart D. Manufacturers may not begin labeling motorcycles with the new FEL until they have received EPA approval to do so.
(3) Manufacturers may not change the FEL of any motorcycle that has been placed into service or that is no longer in their possession.
