D. §86.1810 General standards; increase in emissions; unsafe conditions; waivers

1. §86.1810-09. July 6, 2011 October 15, 2012 Amend §86.1810-09 as follows:

This section applies to mode l year 2015 and later light-dut y vehicles, light-duty trucks, and medium-duty vehicles fueled by gasoline, diesel, methanol, ethanol, natural gas and liquefied petroleum gas fuels. Multi-fueled vehicles (including bi -fueled, dual-fueled and flexible-fueled vehicles) shall co mply with all requirements established for each consumed fuel6
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 (or blend of fuels in the case of flexible-fueled vehicles). This section also applies to hybrid electric vehicles. The standards of this subpart apply to both certificati on and in-use vehicles
unless otherwise indicated.

* * * *

(p) Amend as follows: For gasoline and diesel-fueled LEV II and LEV III vehicles, manufacturers may measure non-methane hydroc arbons (NMHC) in lieu of NMOG. For
LEV II vehicles that are certifi ed using the California Gasoline Fuel Specifications set forth in Part II, section 100.3.1.1, manufacturers must multiply NMHC measurements by an adjustment factor of 1.04 before compar ing with the NMOG standard to determine compliance with the standard. For LEV III vehi cles and LEV II vehicles that are certified using the California Gasoline Fuel Specifica tions set forth in Part II, section 100.3.1.2, manufacturers must multiply NMHC measuremen ts by an adjustment factor of 1.10 before adding it to the measured NOx emissions a nd comparing with the NMOG+NOx standard to determine compliance with that standard. For LEV III vehicles and LEV II vehicles that are certified using a gasoline fuel that contains an ethanol conten t greater than that allowed by the California Gasoline Fuel Specifications set forth in Part II, sect ion 100.3.1.2 and less than or equal to 25 percent ethanol, the adjustment factor that must be used to demonstrate compliance with this paragraph is cal culated using the following formula: Adjustment factor = 1

. 0302 + 0.0071 x volume percent fuel ethanol where the value for the “volume percent fuel ethanol” used in this formula is 15 if the gasoline contains 15 percent ethanol, the “volume percent fuel ethanol” us ed in this formula is 20 if the gasoline contains 20 percent ethanol, etc. Manufacturers must multiply NMHC measurements by this calculated adjustment factor before adding it to the measured NOx emissions and comparing with the NMOG+NOx st andard to determine compliance with that
standard. Manufacturers may use other factors to adjust NMHC results to more properly represent NMOG results. Such factors must be based upon comparative testing of NMOG and NMHC emissions and be approved in advance by the Administrator.

1.1.2.1.4 Alternative Phase-in Schedul e for Particulate Standards.

1.1.2.1.4.1 Alternative Phase-in Schedules for the 3 mg/mi Particulate Standard for Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger Vehicles. A manufacturer may use an a lternative phase-in schedule to comply with the 3 mg/mi particulate sta ndard phase-in requirements as long as equivalent PM emission reductions ar e achieved by the 2021 model year from passenger cars, light-duty trucks, and me dium-duty passenger vehicles. Model year emission reductions shall be cal culated by multiplying the percent of PC+LDT+MDPV vehicles meeting the 3 mg /mi particulate standard in a given model year (based on a manufacturer's proj ected sales volume of vehicles in each category) by 5 for the 2017 model year, 4 for the 2018 model year, 3 for the 2019 model year, 2 for the 2020 model year, and 1 for the 2021 model year. The yearly
results for PC+LDT+MDPV vehicles shall be summed together to determine a
cumulative total for PC+LDT+MDPV vehi cles. In the 2021 model year, tThe cumulative total must be equal to or greater than 490, and 100 percent of the manufacturer’s passenger cars, light- duty trucks, and medium-duty passenger vehicles must be certified to the 3 mg/m i particulate standard , in the 2021 model year to be considered equivalent. A ma nufacturer may add vehicles introduced before the 2017 model year (e.g., the per cent of vehicles in troduced in 2016 would be multiplied by 5) to the cumulative total.

1.1.2.1.4.2 Alternative Phase-in Schedules for the 1 mg/mi Particulate Standard for Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger Vehicles. A manufacturer may use an a lternative phase-in schedule to comply with the 1 mg/mi particulate sta ndard phase-in requirements as long as equivalent PM emission reductions ar e achieved by the 2028 model year from passenger cars, light-duty trucks, and me dium-duty passenger vehicles. Model year emission reductions shall be cal culated by multiplying the percent of PC+LDT+MDPV vehicles meeting the 1 mg /mi particulate standard in a given model year (based on a manufacturer's proj ected sales volume of vehicles in each category) by 4 for the 2025 model year, 3 for the 2026 model year, 2 for the 202710
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 model year, and 1 for the 2028 model year. The yearly results for PC+LDT+MDPV vehicles shall be summed together to determine a cumulative
total for PC+LDT+MDPV vehicles. In the 2028 model year, tThe cumulative total must be equal to or greater than 500 and 100 per cent of the manufacturer’s passenger cars, light-duty trucks, and medi um-duty passenger vehicles must be certified to the 1 mg/mi particulate st andard in the 2028 model year to be considered equivalent. A manufacturer may add vehicles introduced before the 2025 model year (e.g., the percent of ve hicles introduced in 2024 would be multiplied by 4) to the cumulative total.

1.1.2.1.4.3 Alternative Phase-in Sche dules for the Particulate Standards for Medium-Duty Vehicles Other than Medium-Duty Passenger
Vehicles. A manufacturer may use an altern ative phase-in schedule to comply with the particulate standard phase-in requirements as long as equivalent PM emission reductions are achieved by the 2021 model year from medium-duty vehicles other than medium-duty passe nger vehicles. Model year emission reductions shall be calculated by multiplyi ng the total percent of MDVs certified to the 8 mg/mi PM standard or to the 10 mg/mi PM standard, as applicable, in a given model year (based on a manufacturer's projected sales volume of vehicles in each category) by 5 for the 2017 model year , 4 for the 2018 model year, 3 for the 2019 model year, 2 for the 2020 model year, and 1 for the 2021 model year. The yearly results for MDVs shall be summed together to determine a cumulative total for MDVs. In the 2021 model year, tT he cumulative total must be equal to or greater than 490, and 100 per cent of the manufacturer’s MDVs must be certified to the 8 mg/mi PM standard or to the 10 mg /mi PM standard, as applicable, in the 2021 model year to be considered equivale nt. A manufacturer may add vehicles introduced before the 2017 model year (e.g., the percent of vehicl es introduced in 2016 would be multiplied by 5) to the cumulative total.

1.2.2.1.2 SFTP NMOG+NOx and CO Composite Exhaust
Emission Standards. For the 2015 and subsequent model years, a manufacturer must certify LEV II and LEV III LEVs, ULEVs, and SULEVs, such that the manufacturer’s sales-weighted fleet -average NMOG+NOx composite emission value, does not exceed the applicable NMOG+NOx composite emission standard set forth in the following table. In ad dition, the CO composite emission value of any LEV III test group shall not exceed the CO composite emission standard set forth in the following table. SFTP compliance shall be demonstrated using the same gaseous or liquid fuel used for FTP certification. In the case of fuel-flexible vehicles, SFTP compliance shall be dem onstrated using the LEV III certification gasoline specified in Pa rt II, Section A.100.3.1.2.

For each test group subject to this subsection, manufacturers shall calculate a Composite Emission Valu e for NMOG+NOx and, for LEV III test groups, a separate Composite Emission Value for CO, using the following equation:

Composite Emission Value = 0.28 x US06 + 0.37 x SC03 + 0.35 x FTP [Eq. 1]

where “US06” = the test group’s NMOG+NOx or CO emission value, as applicable, determined through the US06 test; “SC03” = the test group’s NMOG+NOx or CO emission value, as applicable, determined th rough the SC03 test; and “FTP” = the test group’s NMOG+NOx or CO emission value, as applicable, determined through the FTP test.

If no vehicles in a test group have air conditioning units, the FTP cycle emission value can be used in place of the SC03 value in Equation 1. To determine compliance with the SFTP NMOG+NOx composite emission standard applicable to the model year, manufactur ers shall use a sales-weighted fleet average of the NMOG+NOx composite emissi on values of every applicable test group. The sales-weighted fleet average shall be calculated using a combination of carry-over and new certification SFTP composite emission values (converted to NMOG+NOx, as applicable). LEV II test groups will use their emission values in the fleet average calculati on but will not be consider ed LEV III test groups. Compliance with the CO composite emi ssion standard cannot be demonstrated through fleet averaging. The NMOG+ NOx sales-weighted fleet-average13
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 composite emission value for the fleet and the CO composite emission value for each test group shall not exceed:

basis shall also certify to the SFTP on a 150,000-mile durabil ity basis, as tested in accordance with these test procedures.

2 Determining NMOG+NOx Composite Emission Values of LEV II Test Groups and Clea ner Federal Vehicles. For test groups certified to LEV II FTP emission standards, SFTP emission values shall be converted to NMOG+NOx and projected out to 120,000 miles or 150,000 miles (dependi ng on LEV II FTP certifi cation) using deterioration factors or aged components. NMHC emission values for th e US06 and SC03 test cycles shall be converted to NMOG emission values by multiplying by a factor of 1.03. In lieu of deriving a deterioration factor specific to SFTP test cycles, carry-over LEV II test groups ma y use the applicable dete rioration factor from the FTP cycle in order to determine the carry-over composite emission values fo r the purpose of the NMOG+NOx sales-weighted fleetaverage calculation. If an SFTP full-useful life emission value is used to comply with the LEV II SFTP 4k standards, that value may be used in the sales-weighted fleet-average without applying an additional deterioration factor. For federally-certified test groups certifying in Ca lifornia in accordance with Section H subparagraph 1.4, the full-useful life emission value used to comply with fede ral full-useful life SFTP require ments may be used in the sales-weighted fleet-average without applying an additio nal deterioration factor. In all cases, NMHC emission values for the US06 and SC03 test cycles shall be converted to NMOG emission values by multiplying by a factor of

1.03.

3 MDPVs are excluded from SFTP NMOG+NOx and CO emission standards and the sales-weighted fleet average

until they are certified to LEV III FTP 150,000-mile NMOG+NOx and CO requirements.

4 LEV III Ttest groups shall certify to bins in increments of 0.010 g/mi. Beginn ing with the 2018 model year, vehicles

may not certify to bin values above a maximum of 0.180 g/mi

. 5 Calculating the sales-weighted average for NMOG+NOx. For each model year, the manufacturer shall calculate its

100.5.6 AC17 Air Conditioning Effi ciency Test Procedure. 1. Overview. The dynamometer operation consists of four elements: a preconditioning cycle, a 30-minute soak peri od under simulated solar heat, an SC03 drive cycle, and a Highway Fuel Economy Test (HWFET) drive cycle. The vehicle is preconditioned with the UDDS to bring the ve hicle to a warmed-up stabilized condition. This preconditioning is followed by a 30 minute vehicle soak (engine off) that proceeds directly into the SC03 driving schedule, duri ng which continuous proportional samples of gaseous emissions are collected for analys is. The SC03 driving schedule is followed immediately by the HWFET cycle, during wh ich continuous proportional samples of gaseous emissions are collected for an alysis. The entire test, including the preconditioning driving, vehicle soak, and SC03 and HWFET o fficial test cycles, is conducted in an environmental test facility. The environmental test facility must be capable of providing the following nominal ambient test conditi ons of: 77 °F air temperature, 50 percent relative humidity, a so lar heat load intens ity of 850 W/m2, and vehicle cooling air flow proportional to vehicle speed. Section §86.161–00 discusses the minimum facility requirements and correspondi ng control tolerances for air conditioning
ambient test conditions. The entire test se quence is run twice; with and without the vehicle's air conditioner opera ting during the SC03 and HFET test cycles. For gasoline-30
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 fueled Otto-cycle vehicles, the composite sa mples collected in bags are analyzed for THC, CO, CO 2 , and CH 4 . For petroleum-fueled diesel-c ycle vehicles, THC is sampled and analyzed continuously according to the provisions of §86.110. Parallel bag samples
of dilution air are anal yzed for THC, CO, CO 2 , and CH 4 . The following figure shows the basic sequence of the test procedure.

As Amended: December 6, 2012 Date of Hearing: November 15, 2012 2.2 Position (vehicle can be driven) th e test vehicle on the dynamometer and
restrain. 2.3 Required dynamometer inertia weight class selections are determined by the test vehicle’s test weight basis and corresponding equivale nt weight as listed in the tabular information of §86.129–00(a) a nd discussed in §86.129–00 (e) and (f). 2.4 Set the dynamometer test inertia weight and roadload horsepower requirements for the test vehicle (s ee §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 ro ad load force at all speeds. 2.5 The vehicle speed as measured from the dynamometer rolls shall be used. A speed vs. time recording, as evidence of dynamo meter test validity, shall be supplied at request of the Executive Officer. 2.6 The drive wheel tires may be inflated up to a gauge pressure of 45 psi (310 kPa), or the manufacturer's recommended pre ssure if higher than 45 psi, in order to prevent tire damage. The drive wh eel tire pressure shall be re ported with the test results. 2.7 The driving distance, as meas ured by counting the number of dynamometer roll or shaft revolutions, shall be determined for the test.
2.8 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 twowheel drive mode, four-wheel drive and all-wheel drive vehicles may have one set of drive wheels disengaged; four-w heel and all-wheel drive vehicl es which can be shifted to a two-wheel mode by the driver may be tested in a two-wheel drive mode of operation.

3. Test cell ambient conditions

. 3.1 Ambient air temperature

. 3.1.1 Ambient air temperature is controll ed, within the test cell, during all phases of the test sequence to 77 ±2 °F on average and 77 ±5 °F as an instantaneous

measurement. 3.1.2 Air temperature is recorded conti nuously 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.

3.2 Ambient humidity

. 3.2.1 Ambient humidity is controlled, within the test cell, during all phases of the test sequence to an av erage of 69 ±5 grains of water/pound of dry air. 3.2.2 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 certi fication related programs.

3.3 Solar heat loading . The requirements of 86.161-00(d) regarding solar heat loading specifications shall apply. The solar load of 850 W/m 2 is applied only during specified portions of the test sequence.

4. Interior temperature measurement . The interior temperature of the vehicle shall be measured during the em ission sampling phases of the test(s). 4.1 Interior temperatures shall be meas ured by placement of thermocouples at the following locations:
4.1.1 The outlet of the cen ter duct on the dash.32
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 4.1.2 Behind the driver and passenger seat headrests. The location of the temperature measuring devices shall be 30 mm behind each headrest and 330 mm below
the roof. 4.2 The temperature at each location shal l be recorded a minimum of every 5
seconds.

5. Air conditioning system settings . For the portion of the test where the air conditioner is required to be opera ting the settings shall be as follows: 5.1 Automatic systems shall be set to automatic and the temperature control

set to 72 °F. 5.2 Manual systems shall be set at the star t of the SC03 drive cycle to full cool with the fan on the highest set ting and the airflow setting to “recirculation.” Within the first idle period of the SC03 drive cycle (186 to 204 seconds) the fan speed shall be reduced to the setting closest to 6 volts at the motor, the temperature setting shall be adjusted to provide 55 °F at the center dash air outlet, and the airf low setting changed to
“outside air.”

6. Vehicle and test activities . The AC17 air conditioning test in an
environmental test cell is composed of the following sequence of activities.
6.1 Drain and fill the vehicle's fuel tank to 40 percent capacity with test fuel. If a vehicle has gone through the drain and fu el sequence less than 72 hours previously and has remained under laboratory ambient te mperature conditions, this drain and fill operation can be omitted (see §86.132–00(c)(2)(ii)). 6.2.1 Position the variable speed cooling fan in front of the test vehicle with the vehicle's hood down. This air flow should provide representative coolin g at the front of the test vehicle (air conditioning condenser and engine) during the driving cycles. See §86.161–00(e) for a discussion of cooling fan specifications.
6.2.2 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 sufficien t 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 ad ditional 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 Executive Officer. 6.3 Open all vehicle windows. 6.4 Connect the emission test sampling system to the vehicle's exhaust tail pipe(s).
6.5 Set the environmental test cell ambi ent test conditions to the conditions defined in paragraph (c) of this section, except that the solar heat shall be off. 6.6 Set the air conditioning system controls to off. 6.7 Start the vehicle (with air condi tioning system off) and conduct a preconditioning EPA urban dynamome ter driving cycle (§86.115). 6.7.1 If engine stalling should occur during any air conditioning test cycle operation, follow the provisions of § 86.136–90 (Engine starting and restarting). 6.7.2 For manual transmission vehicles, the vehicle shall be shifted according the provisions of §86.128–00.33
As Amended: December 6, 2012 Date of Hearing: November 15, 2012 6.8 Following the preconditioning cycle, th e test vehicle and cooling fan(s) are turned off, all windows are rolled up, a nd the vehicle is allowed to soak in the ambient conditions of paragraph (c)(1) of this section for 30 ±1 minutes. The solar heat system must be turned on and generating 850 W/m 2 within 1 minute of turning the engine
off.

6.9 Air conditioning on test

. 6.9.1 Start engine (with air conditioning sy stem also running). Fifteen seconds after the engine starts , place vehicle in gear. 6.9.2 Eighteen seconds after the engine starts, begin the initial vehicle
acceleration of the SC 03 driving schedule. 6.9.3 Operate the vehicle according to the SC03 driving schedule, as described in 40 CFR Part 86 Appendix I, paragraph (h ), while sampling the exhaust gas.
6.9.4 At the end of the deceleration which is scheduled to occur at 594 seconds, simultaneously switch the sample flows fr om the SC03 bags and samples to the “HWFET” bags and samples, switch off gas flow measuring device No. 1, switch off the No. 1 petroleum-fueled diesel hydrocarbon inte grator, mark the petroleum-fueled diesel hydrocarbon recorder chart, and start gas flow measuring device No. 2, and start the petroleum-fueled diesel hydr ocarbon integrator No. 2.
6.9.5 Allow the vehicle to idle for 14-16 s econds. Before the end of this idle period, record the measured roll or shaft revol utions and reset the c ounter or switch to a second counter. As soon as possible transfer the SC03 exhaust and dilution air samples to the analytical system and process the samp les according to §86.140 obtaining a stabilized reading of the bag exhaust sample on all anal yzers within 20 minutes of the end of the sample collection phase of th e test. Obtain methanol and formaldehyde sample analyses, if applicable, within 24 hour s of the end of the sample collection phase of the test. 6.9.6 Operate the vehicle according to the HWFET driving schedule, as described in 40 CFR 600.109-08, while sampling the exhaust gas. 6.9.7 Turn the engine off 2 seconds after the end of the last deceleration. 6.9.8 Five seconds after the engine stops running, simultaneously turn off gas flow measuring device No. 2 and if applicab le, turn off the petroleum-fueled diesel hydrocarbon integrator No. 2, mark the hydroc arbon recorder chart, and position the sample selector valves to the “standby” pos ition. Record the m easured roll or shaft revolutions (both gas meter or flow measurem ent instrumentation readings), and re-set the counter. As soon as possibl e, transfer the HWFET exhaus t and dilution air samples to the analytical system and process th e samples according to §86.140, obtaining a stabilized reading of the exha ust bag sample on all analyzers within 20 minutes of the end of the sample collection phase of the test. Obtain methanol and formaldehyde sample analyses, if applicable, within 24 hours of the en d of the sample period.

6.10 Air conditioning off test . The air conditioning off test is identical to the steps identified in paragraphs 6.1 through 6.9 of this section, except that the air conditioning system and fan speeds are set to co mplete off or the lowe st. It is preferred that the air conditioning off te st be conducted sequentially after the air conditioning on test, following a 10-15 minute soak.
