Download as PDF Federal Register / Vol. 85, No. 197 / Friday, October 9, 2020 / Notices ENVIRONMENTAL PROTECTION AGENCY [EPA–HQ–OAR–2019–0333; FRL–10015–09– OAR] Alternative Methods for Calculating Off-Cycle Credits Under the Light-Duty Vehicle Greenhouse Gas Emissions Program: Applications From Toyota Motor North America Environmental Protection Agency (EPA). ACTION: Notice. AGENCY: The Environmental Protection Agency (EPA) is requesting comment on applications from Toyota Motor North America (‘‘Toyota’’) for off-cycle carbon dioxide (CO2) credits under EPA’s lightduty vehicle greenhouse gas emissions standards. ‘‘Off-cycle’’ emission reductions can be achieved by employing technologies that result in real-world benefits, but where that benefit is not adequately captured on the test procedures used by manufacturers to demonstrate compliance with emission standards. EPA’s light-duty vehicle greenhouse gas program acknowledges these benefits by giving automobile manufacturers several options for generating ‘‘off-cycle’’ CO2 credits. Under the regulations, a manufacturer may apply for CO2 credits for off-cycle technologies that result in off-cycle benefits. In these cases, a manufacturer must provide EPA with a proposed methodology for determining the real-world off-cycle benefit. Toyota has submitted applications that describe methodologies for determining off-cycle credits from technologies described in their applications. Pursuant to applicable regulations, EPA is making these off-cycle credit calculation methodologies available for public comment. SUMMARY: Comments must be received on or before November 9, 2020. ADDRESSES: Submit your comments, identified by Docket ID No. EPA–HQ– OAR–2019–0333, to the Federal eRulemaking Portal: https:// www.regulations.gov. Follow the online instructions for submitting comments. Once submitted, comments cannot be edited or withdrawn. The EPA may publish any comment received to its public docket. Do not submit electronically any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment. The written comment is considered the official comment and DATES: VerDate Sep<11>2014 17:26 Oct 08, 2020 Jkt 253001 should include discussion of all points you wish to make. The EPA will generally not consider comments or comment contents located outside of the primary submission (i.e., on the web, cloud, or other file sharing system). For additional submission methods, the full EPA public comment policy, information about CBI or multimedia submissions, and general guidance on making effective comments, please visit https://www2.epa.gov/dockets/ commenting-epa-dockets.

Background EPA’s light-duty vehicle greenhouse gas (GHG) program provides three pathways by which a manufacturer may accrue off-cycle carbon dioxide (CO2) credits for those technologies that achieve CO2 reductions in the real world but where those reductions are not adequately captured on the test used to determine compliance with the CO2 standards, and which are not otherwise reflected in the standards’ stringency. The first pathway is a predetermined list of credit values for specific off-cycle technologies that may be used beginning in model year 2014.1 This pathway allows manufacturers to use conservative credit values established by EPA for a wide range of technologies, with minimal data submittal or testing requirements, if the technologies meet EPA regulatory definitions. In cases where the off-cycle technology is not on the menu but additional laboratory testing can demonstrate emission benefits, a second pathway allows manufacturers to use a broader array of emission tests (known as ‘‘5-cycle’’ testing because the methodology uses five different testing procedures) to demonstrate and justify off-cycle CO2 credits.2 The additional emission tests allow emission benefits to be demonstrated over some elements of real-world driving not adequately captured by the GHG compliance tests, including high speeds, hard accelerations, and cold temperatures. These first two methodologies were completely defined through notice and comment rulemaking and therefore no additional process is necessary for 1 See 2 See PO 00000 40 CFR 86.1869–12(b). 40 CFR 86.1869–12(c). Frm 00036 Fmt 4703 Sfmt 4703 64143 manufacturers to use these methods. The third and last pathway allows manufacturers to seek EPA approval to use an alternative methodology for determining the off-cycle CO2 credits.3 This option is only available if the benefit of the technology cannot be adequately demonstrated using the 5cycle methodology. Manufacturers may also use this option to demonstrate reductions that exceed those available via use of the predetermined list. Under the regulations, a manufacturer seeking to demonstrate off-cycle credits with an alternative methodology (i.e., under the third pathway described above) must describe a methodology that meets the following criteria: • Use modeling, on-road testing, onroad data collection, or other approved analytical or engineering methods; • Be robust, verifiable, and capable of demonstrating the real-world emissions benefit with strong statistical significance; • Result in a demonstration of baseline and controlled emissions over a wide range of driving conditions and number of vehicles such that issues of data uncertainty are minimized; • Result in data on a model type basis unless the manufacturer demonstrates that another basis is appropriate and adequate. Further, the regulations specify the following requirements regarding an application for off-cycle CO2 credits: • A manufacturer requesting off-cycle credits must develop a methodology for demonstrating and determining the benefit of the off-cycle technology and carry out any necessary testing and analysis required to support that methodology. • A manufacturer requesting off-cycle credits must conduct testing and/or prepare engineering analyses that demonstrate the in-use durability of the technology for the full useful life of the vehicle. • The application must contain a detailed description of the off-cycle technology and how it functions to reduce CO2 emissions under conditions not represented on the compliance tests. • The application must contain a list of the vehicle model(s) which will be equipped with the technology. • The application must contain a detailed description of the test vehicles selected and an engineering analysis that supports the selection of those vehicles for testing. • The application must contain all testing and/or simulation data required under the regulations, plus any other 3 See E:\FR\FM\09OCN1.SGM 40 CFR 86.1869–12(d). 09OCN1 64144 Federal Register / Vol. 85, No. 197 / Friday, October 9, 2020 / Notices data the manufacturer has considered in the analysis. Finally, the alternative methodology must be approved by EPA prior to the manufacturer using it to generate credits. As part of the review process defined by regulation, the alternative methodology submitted to EPA for consideration must be made available for public comment.4 EPA will consider public comments as part of its final decision to approve or deny the request for off-cycle credits. II. Off-Cycle Credit Applications A. Cold-Storage Evaporator Toyota is applying for off-cycle GHG credits for the use of Cold-Storage Evaporator HVAC Technology. This technology utilizes phase change material in the HVAC evaporator of vehicles equipped with engine Start & Stop technology to extend the time that cold air can be delivered to the cabin with the engine and compressor off. This reduces the amount of time the engine would otherwise operate solely for the purpose of cooling the cabin. Toyota is applying for a credit of 0.8 or 1.3 grams/mile (dependent on HVAC configuration) for 2017 and later model years vehicles sold in the U.S. and equipped with the cold storage evaporator. Details of the testing and analysis can be found in the manufacturer’s applications. B. Denso LE40 Low Power Compressor Clutch Toyota is applying for off-cycle GHG credits for the use of the DENSO LE40 compressor clutch. The LE40 compressor clutch is designed to improve the compressor efficiency by reducing the electric current required to transmit torque from the engine to the compressor. Toyota is applying for a credit of 0.3 grams/mile for 2016 and later model years for vehicles sold in the U.S. and equipped with the Denso LE40 Compressor Clutch. EPA considers this compressor clutch technology to be a technology that, if approved, will be subject to the maximum limits for an A/C system of 5.0 g/mi for passenger automobiles and 7.2 g/mi for light trucks specified in the regulations.5 Details of the testing and analysis can be found in the manufacturer’s applications. C. Seat Heater Engine Control Technology Toyota is applying for off-cycle GHG credits for a hybrid control strategy that 4 See 5 See 17:26 Oct 08, 2020 III. EPA Decision Process EPA has reviewed the applications for completeness and is now making the applications available for public review and comment as required by the regulations. The off-cycle credit applications submitted by the manufacturers (with confidential business information redacted) have been placed in the public docket (see ADDRESSES section above) and on EPA’s website at https://www.epa.gov/vehicleand-engine-certification/complianceinformation-light-duty-greenhouse-gasghg-standards. EPA is providing a 30-day comment period on the applications for off-cycle credits described in this notice, as specified by the regulations. The manufacturers may submit a written rebuttal of comments for EPA’s consideration, or may revise an application in response to comments. After reviewing any public comments and any rebuttal of comments submitted by manufacturers, EPA will make a final decision regarding the credit requests. EPA will make its decision available to the public by placing a decision document (or multiple decision documents) in the docket and on EPA’s website at the same manufacturerspecific pages shown above. While the broad methodologies used by these manufacturers could potentially be used for other vehicles and by other manufacturers, the vehicle specific data needed to demonstrate the off-cycle emissions reductions would likely be different. In such cases, a new application would be required, including an opportunity for public comment. Dated: October 5, 2020.

captured on the test procedures used by manufacturers to demonstrate 
compliance with emission standards. EPA's light-duty vehicle greenhouse 
gas program acknowledges these benefits by giving automobile 
manufacturers several options for generating ``off-cycle'' 
CO2 credits. Under the regulations, a manufacturer may apply 
for CO2 credits for off-cycle technologies that result in 
off-cycle benefits. In these cases, a manufacturer must provide EPA 
with a proposed methodology for determining the real-world off-cycle 
benefit. Toyota has submitted applications that describe methodologies 
for determining off-cycle credits from technologies described in their 
applications. Pursuant to applicable regulations, EPA is making these 
off-cycle credit calculation methodologies available for public 
comment.

SUPPLEMENTARY INFORMATION:

I. Background

    EPA's light-duty vehicle greenhouse gas (GHG) program provides 
three pathways by which a manufacturer may accrue off-cycle carbon 
dioxide (CO2) credits for those technologies that achieve 
CO2 reductions in the real world but where those reductions 
are not adequately captured on the test used to determine compliance 
with the CO2 standards, and which are not otherwise 
reflected in the standards' stringency. The first pathway is a 
predetermined list of credit values for specific off-cycle technologies 
that may be used beginning in model year 2014.\1\ This pathway allows 
manufacturers to use conservative credit values established by EPA for 
a wide range of technologies, with minimal data submittal or testing 
requirements, if the technologies meet EPA regulatory definitions. In 
cases where the off-cycle technology is not on the menu but additional 
laboratory testing can demonstrate emission benefits, a second pathway 
allows manufacturers to use a broader array of emission tests (known as 
``5-cycle'' testing because the methodology uses five different testing 
procedures) to demonstrate and justify off-cycle CO2 
credits.\2\ The additional emission tests allow emission benefits to be 
demonstrated over some elements of real-world driving not adequately 
captured by the GHG compliance tests, including high speeds, hard 
accelerations, and cold temperatures. These first two methodologies 
were completely defined through notice and comment rulemaking and 
therefore no additional process is necessary for manufacturers to use 
these methods. The third and last pathway allows manufacturers to seek 
EPA approval to use an alternative methodology for determining the off-
cycle CO2 credits.\3\ This option is only available if the 
benefit of the technology cannot be adequately demonstrated using the 
5-cycle methodology. Manufacturers may also use this option to 
demonstrate reductions that exceed those available via use of the 
predetermined list.

---------------------------------------------------------------------------

    Under the regulations, a manufacturer seeking to demonstrate off-
cycle credits with an alternative methodology (i.e., under the third 
pathway described above) must describe a methodology that meets the 
following criteria:
     Use modeling, on-road testing, on-road data collection, or 
other approved analytical or engineering methods;
     Be robust, verifiable, and capable of demonstrating the 
real-world emissions benefit with strong statistical significance;
     Result in a demonstration of baseline and controlled 
emissions over a wide range of driving conditions and number of 
vehicles such that issues of data uncertainty are minimized;
     Result in data on a model type basis unless the 
manufacturer demonstrates that another basis is appropriate and 
adequate.
    Further, the regulations specify the following requirements 
regarding an application for off-cycle CO2 credits:
     A manufacturer requesting off-cycle credits must develop a 
methodology for demonstrating and determining the benefit of the off-
cycle technology and carry out any necessary testing and analysis 
required to support that methodology.
     A manufacturer requesting off-cycle credits must conduct 
testing and/or prepare engineering analyses that demonstrate the in-use 
durability of the technology for the full useful life of the vehicle.
     The application must contain a detailed description of the 
off-cycle technology and how it functions to reduce CO2 
emissions under conditions not represented on the compliance tests.
     The application must contain a list of the vehicle 
model(s) which will be equipped with the technology.
     The application must contain a detailed description of the 
test vehicles selected and an engineering analysis that supports the 
selection of those vehicles for testing.
     The application must contain all testing and/or simulation 
data required under the regulations, plus any other

[[Page 64144]]

data the manufacturer has considered in the analysis.
    Finally, the alternative methodology must be approved by EPA prior 
to the manufacturer using it to generate credits. As part of the review 
process defined by regulation, the alternative methodology submitted to 
EPA for consideration must be made available for public comment.\4\ EPA 
will consider public comments as part of its final decision to approve 
or deny the request for off-cycle credits.

II. Off-Cycle Credit Applications

A. Cold-Storage Evaporator

    Toyota is applying for off-cycle GHG credits for the use of Cold-
Storage Evaporator HVAC Technology. This technology utilizes phase 
change material in the HVAC evaporator of vehicles equipped with engine 
Start & Stop technology to extend the time that cold air can be 
delivered to the cabin with the engine and compressor off. This reduces 
the amount of time the engine would otherwise operate solely for the 
purpose of cooling the cabin.
    Toyota is applying for a credit of 0.8 or 1.3 grams/mile (dependent 
on HVAC configuration) for 2017 and later model years vehicles sold in 
the U.S. and equipped with the cold storage evaporator. Details of the 
testing and analysis can be found in the manufacturer's applications.

B. Denso LE40 Low Power Compressor Clutch

    Toyota is applying for off-cycle GHG credits for the use of the 
DENSO LE40 compressor clutch. The LE40 compressor clutch is designed to 
improve the compressor efficiency by reducing the electric current 
required to transmit torque from the engine to the compressor.
    Toyota is applying for a credit of 0.3 grams/mile for 2016 and 
later model years for vehicles sold in the U.S. and equipped with the 
Denso LE40 Compressor Clutch. EPA considers this compressor clutch 
technology to be a technology that, if approved, will be subject to the 
maximum limits for an A/C system of 5.0 g/mi for passenger automobiles 
and 7.2 g/mi for light trucks specified in the regulations.\5\ Details

    \5\ See 40 CFR 86.1868-12(b).
---------------------------------------------------------------------------

C. Seat Heater Engine Control Technology

    Toyota is applying for off-cycle GHG credits for a hybrid control 
strategy that reduces fuel consumption during warm up while the seat 
heater is turned on. When the seat heater is used, less thermal energy 
is required from the engine to maintain comfort. This strategy lowers 
the target engine coolant temperature threshold allowing the engine to 
turn off earlier and more frequently to reduce fuel consumption.
    Toyota is applying for a credit of 0.6 grams/mile for 2019 and 
later model years for vehicles sold in the U.S. and equipped with seat 
heater engine control technology. Details of the testing and analysis 
can be found in the manufacturer's applications.

III. EPA Decision Process

    EPA has reviewed the applications for completeness and is now 
making the applications available for public review and comment as 
required by the regulations. The off-cycle credit applications 
submitted by the manufacturers (with confidential business information 
redacted) have been placed in the public docket (see ADDRESSES section 
above) and on EPA's website at https://www.epa.gov/vehicle-and-engine-certification/compliance-information-light-duty-greenhouse-gas-ghg-standards.
    EPA is providing a 30-day comment period on the applications for 
off-cycle credits described in this notice, as specified by the 
regulations. The manufacturers may submit a written rebuttal of 
comments for EPA's consideration, or may revise an application in 
response to comments. After reviewing any public comments and any 
rebuttal of comments submitted by manufacturers, EPA will make a final 
decision regarding the credit requests. EPA will make its decision 
available to the public by placing a decision document (or multiple 
decision documents) in the docket and on EPA's website at the same 
manufacturer-specific pages shown above. While the broad methodologies 
used by these manufacturers could potentially be used for other 
vehicles and by other manufacturers, the vehicle specific data needed 
to demonstrate the off-cycle emissions reductions would likely be 
different. In such cases, a new application would be required, 
including an opportunity for public comment.
