Sec.  600.201-12  General applicability.

    The provisions of this subpart are applicable to 2012 and later
model year automobiles and to the manufacturers of 2012 and later model
year automobiles.

0
47. A new Sec.  600.206-12 is added to subpart C to read as follows:

Sec.  600.206-12  Calculation and use of FTP-based and HFET-based fuel
economy and carbon-related exhaust emission values for vehicle
configurations.

    (a) Fuel economy and carbon-related exhaust emissions values
determined for each vehicle under Sec.  600.113(a) and (b) and as
approved in Sec.  600.008-08(c), are used to determine FTP-based city,
HFET-based highway, and combined FTP/Highway-based fuel economy and
carbon-related exhaust emission values for each vehicle configuration
for which data are available.
    (1) If only one set of FTP-based city and HFET-based highway fuel
economy values is accepted for a vehicle configuration, these values,
rounded to the nearest tenth of a mile per gallon, comprise the city
and highway fuel economy values for that configuration. If only one set
of FTP-based city and HFET-based highway carbon-related exhaust
emission values is accepted for a vehicle configuration, these values,
rounded to the nearest gram per mile, comprise the city and highway
carbon-related exhaust emission values for that configuration.
    (2) If more than one set of FTP-based city and HFET-based highway
fuel economy and/or carbon-related exhaust emission values are accepted
for a vehicle configuration:
    (i) All data shall be grouped according to the subconfiguration for
which the data were generated using sales projections supplied in
accordance with Sec.  600.208-12(a)(3).
    (ii) Within each group of data, all fuel economy values are
harmonically averaged and rounded to the nearest 0.0001 of a mile per
gallon and all carbon-related exhaust emission values are
arithmetically averaged and rounded to the nearest tenth of a gram per
mile in order to determine FTP-based city and HFET-based highway fuel
economy and carbon-related exhaust emission values for each
subconfiguration at which the vehicle configuration was tested.
    (iii) All FTP-based city fuel economy and carbon-related exhaust
emission values and all HFET-based highway fuel economy and carbon-
related exhaust emission values calculated in paragraph (a)(2)(ii) of
this section are (separately for city and highway) averaged in
proportion to the sales fraction (rounded to the nearest 0.0001) within
the vehicle configuration (as provided to the Administrator by the
manufacturer) of vehicles of each tested subconfiguration. Fuel economy
values shall be harmonically averaged and carbon-related exhaust
emission values shall be arithmetically averaged. The resultant fuel
economy values, rounded to the nearest 0.0001 mile per gallon, are the
FTP-based city and HFET-based highway fuel economy values for the
vehicle configuration. The resultant carbon-related exhaust emission
values, rounded to the nearest tenth of a gram per mile, are the FTP-
based city and HFET-based highway carbon-related exhaust emission
values for the vehicle configuration.
    (3)(i) For the purpose of determining average fuel economy under
Sec.  600.510-08, the combined fuel economy value for a vehicle
configuration is calculated by harmonically averaging the FTP-based
city and HFET-based highway fuel economy values, as determined in
paragraph (a)(1) or (2) of this section,

weighted 0.55 and 0.45 respectively, and rounded to the nearest 0.0001
mile per gallon. A sample of this calculation appears in Appendix II of
this part.
    (ii) For the purpose of determining average carbon-related exhaust
emissions under Sec.  600.510-08, the combined carbon-related exhaust
emission value for a vehicle configuration is calculated by
arithmetically averaging the FTP-based city and HFET-based highway
carbon-related exhaust emission values, as determined in paragraph
(a)(1) or (2) of this section, weighted 0.55 and 0.45 respectively, and
rounded to the nearest tenth of gram per mile.
    (4) For alcohol dual fuel automobiles and natural gas dual fuel
automobiles the procedures of paragraphs (a)(1) or (2) of this section,
as applicable, shall be used to calculate two separate sets of FTP-
based city, HFET-based highway, and combined fuel economy and carbon-
related exhaust emission values for each configuration.
    (i) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
gasoline or diesel test fuel.
    (ii) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
alcohol or natural gas test fuel.
    (b) If only one equivalent petroleum-based fuel economy value
exists for an electric vehicle configuration, that value, rounded to
the nearest tenth of a mile per gallon, will comprise the petroleum-
based fuel economy for that configuration.
    (c) If more than one equivalent petroleum-based fuel economy value
exists for an electric vehicle configuration, all values for that
vehicle configuration are harmonically averaged and rounded to the
nearest 0.0001 mile per gallon for that configuration.

48. A new Sec.  600.208-12 is added to subpart C to read as follows:

Sec.  600.208-12  Calculation of FTP-based and HFET-based fuel economy
and carbon-related exhaust emission values for a model type.

    (a) Fuel economy and carbon-related exhaust emission values for a
base level are calculated from vehicle configuration fuel economy and
carbon-related exhaust emission values as determined in Sec.  600.206-
12(a), (b), or (c) as applicable, for low-altitude tests.
    (1) If the Administrator determines that automobiles intended for
sale in the State of California are likely to exhibit significant
differences in fuel economy and carbon-related exhaust emission values
from those intended for sale in other states, she will calculate fuel
economy and carbon-related exhaust emission values for each base level
for vehicles intended for sale in California and for each base level
for vehicles intended for sale in the rest of the states.
    (2) In order to highlight the fuel efficiency and carbon-related
exhaust emission values of certain designs otherwise included within a
model type, a manufacturer may wish to subdivide a model type into one
or more additional model types. This is accomplished by separating
subconfigurations from an existing base level and placing them into a
new base level. The new base level is identical to the existing base
level except that it shall be considered, for the purposes of this
paragraph, as containing a new basic engine. The manufacturer will be
permitted to designate such new basic engines and base level(s) if:
    (i) Each additional model type resulting from division of another
model type has a unique car line name and that name appears on the
label and on the vehicle bearing that label;
    (ii) The subconfigurations included in the new base levels are not
included in any other base level which differs only by basic engine
(i.e., they are not included in the calculation of the original base
level fuel economy values); and
    (iii) All subconfigurations within the new base level are
represented by test data in accordance with Sec.  600.010-08(c)(1)(ii).
    (3) The manufacturer shall supply total model year sales
projections for each car line/vehicle subconfiguration combination.
    (i) Sales projections must be supplied separately for each car
line-vehicle subconfiguration intended for sale in California and each
car line/vehicle subconfiguration intended for sale in the rest of the
states if required by the Administrator under paragraph (a)(1) of this
section.
    (ii) Manufacturers shall update sales projections at the time any
model type value is calculated for a label value.
    (iii) The provisions of paragraph (a)(3) of this section may be
satisfied by providing an amended application for certification, as
described in Sec.  86.1844-01 of this chapter.
    (4) Vehicle configuration fuel economy and carbon-related exhaust
emission values, as determined in Sec.  600.206-12 (a), (b) or (c), as
applicable, are grouped according to base level.
    (i) If only one vehicle configuration within a base level has been
tested, the fuel economy and carbon-related exhaust emission values
from that vehicle configuration will constitute the fuel economy and
carbon-related exhaust emission values for that base level.
    (ii) If more than one vehicle configuration within a base level has
been tested, the vehicle configuration fuel economy values are
harmonically averaged in proportion to the respective sales fraction
(rounded to the nearest 0.0001) of each vehicle configuration and the
resultant fuel economy value rounded to the nearest 0.0001 mile per
gallon; and the vehicle configuration carbon-related exhaust emission
values are arithmetically averaged in proportion to the respective
sales fraction (rounded to the nearest 0.0001) of each vehicle
configuration and the resultant carbon-related exhaust emission value
rounded to the nearest gram per mile.
    (5) The procedure specified in paragraph (a)(1) through (4) of this
section will be repeated for each base level, thus establishing city,
highway, and combined fuel economy and carbon-related exhaust emission
values for each base level.
    (6) For the purposes of calculating a base level fuel economy or
carbon-related exhaust emission value, if the only vehicle
configuration(s) within the base level are vehicle configuration(s)
which are intended for sale at high altitude, the Administrator may use
fuel economy and carbon-related exhaust emission data from tests
conducted on these vehicle configuration(s) at high altitude to
calculate the fuel economy or carbon-related exhaust emission value for
the base level.
    (7) For alcohol dual fuel automobiles and natural gas dual fuel
automobiles, the procedures of paragraphs (a)(1) through (6) of this
section shall be used to calculate two separate sets of city, highway,
and combined fuel economy and carbon-related exhaust emission values
for each base level.
    (i) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
gasoline or diesel test fuel.
    (ii) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
alcohol or natural gas test fuel.
    (b) For each model type, as determined by the Administrator, a
city, highway, and combined fuel economy value and a carbon-related
exhaust emission value will be calculated by using the projected sales
and fuel economy and carbon-related exhaust emission values for each
base level

within the model type. Separate model type calculations will be done
based on the vehicle configuration fuel economy and carbon-related
exhaust emission values as determined in Sec.  600.206-12 (a), (b) or
(c), as applicable.
    (1) If the Administrator determines that automobiles intended for
sale in the State of California are likely to exhibit significant
differences in fuel economy and carbon-related exhaust emission values
from those intended for sale in other states, she will calculate fuel
economy and carbon-related exhaust emission values for each model type
for vehicles intended for sale in California and for each model type
for vehicles intended for sale in the rest of the states.
    (2) The sales fraction for each base level is calculated by
dividing the projected sales of the base level within the model type by
the projected sales of the model type and rounding the quotient to the
nearest 0.0001.
    (3)(i) The FTP-based city fuel economy values of the model type
(calculated to the nearest 0.0001 mpg) are determined by dividing one
by a sum of terms, each of which corresponds to a base level and which
is a fraction determined by dividing:
    (A) The sales fraction of a base level; by
    (B) The FTP-based city fuel economy value for the respective base
level.
    (ii) The FTP-based city carbon-related exhaust emission value of
the model type (calculated to the nearest gram per mile) are determined
by a sum of terms, each of which corresponds to a base level and which
is a product determined by multiplying:
    (A) The sales fraction of a base level; by
    (B) The FTP-based city carbon-related exhaust emission value for
the respective base level.
    (4) The procedure specified in paragraph (b)(3) of this section is
repeated in an analogous manner to determine the highway and combined
fuel economy and carbon-related exhaust emission values for the model
type.
    (5) For alcohol dual fuel automobiles and natural gas dual fuel
automobiles, the procedures of paragraphs (b)(1) through (4) of this
section shall be used to calculate two separate sets of city, highway,
and combined fuel economy values and two separate sets of city,
highway, and combined carbon-related exhaust emission values for each
model type.
    (i) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
gasoline or diesel test fuel.
    (ii) Calculate the city, highway, and combined fuel economy and
carbon-related exhaust emission values from the tests performed using
alcohol or natural gas test fuel.

    (vi) At the manufacturer's option, those vehicle configurations
that are self-compensating to altitude changes may be separated by
sales into high-altitude sales categories and low-altitude sales
categories. These separate sales categories may then be treated (only
for the purpose of this section) as separate configurations in
accordance with the procedure of Sec.  600.208-12(a)(4)(ii).
    (3) The fuel economy and carbon-related exhaust emission values for
each vehicle configuration are the combined fuel economy and carbon-
related exhaust emissions calculated according to Sec.  600.206-
08(a)(3) except that:
    (i) Separate fuel economy values will be calculated for vehicle
configurations associated with car lines for each category of passenger
automobiles and light trucks as determined by the Secretary of
Transportation pursuant to paragraph (a)(1) of this section.
    (ii) Total model year production data, as required by this subpart
will be used instead of sales projections; and

    (c) Except as permitted in paragraph (d) of this section, the
average fuel economy will be calculated individually for each category
identified in paragraph (a)(1) of this section as follows:
    (1) Divide the total production volume of that category of
automobiles; by
    (2) A sum of terms, each of which corresponds to a model type
within that category of automobiles and is a fraction determined by
dividing the number of automobiles of that model type produced by the
manufacturer in the model year; by
    (i) For gasoline-fueled and diesel-fueled model types, the fuel
economy calculated for that model type in accordance with paragraph

provided the requirements of paragraph (g) of this section are met.
    (d) The Administrator may approve alternative calculation methods
if they are part of an approved credit plan under the provisions of 15
U.S.C. 2003.
    (e) For passenger automobile categories identified in paragraph
(a)(1) of this section, the average fuel economy calculated in
accordance with paragraph (c) of this section shall be adjusted using
the following equation:

AFEadj = AFE[((0.55 x a x c) + (0.45 x c) + (0.5556 x a) +
0.4487)/((0.55 x a) + 0.45)] + IW

Where:

to the nearest 0.1 mpg;
AFE = Average combined fuel economy as calculated in paragraph (c)
of this section, rounded to the nearest 0.0001 mpg;
a = Sales-weight average (rounded to the nearest 0.0001 mpg) of all
model type highway fuel economy values (rounded to the nearest 0.1
mpg) divided by the sales-weighted average (rounded to the nearest
0.0001 mpg) of all model type city fuel economy values (rounded to
the nearest 0.1 mpg). The quotient shall be rounded to 4 decimal
places. These average fuel economies shall be determined using the
methodology of paragraph (c) of this section.

category. Round the result to the nearest 0.0001 mpg.

    (f) The Administrator shall calculate and apply additional average
fuel economy adjustments if, after notice and opportunity for comment,
the Administrator determines that, as a result of test procedure
changes not previously considered, such correction is necessary to
yield fuel economy test results that are comparable to those obtained
under the 1975 test procedures. In making such determinations, the
Administrator must find that:
    (1) A directional change in measured fuel economy of an average
vehicle can be predicted from a revision to the test procedures;
    (2) The magnitude of the change in measured fuel economy for any
vehicle or fleet of vehicles caused by a revision to the test
procedures is quantifiable from theoretical calculations or best
available test data;
    (3) The impact of a change on average fuel economy is not due to
eliminating the ability of manufacturers to take advantage of
flexibility within the existing test procedures to gain measured
improvements in fuel economy which are not the result of actual
improvements in the fuel economy of production vehicles;
    (4) The impact of a change on average fuel economy is not solely
due to a greater ability of manufacturers to reflect in average fuel
economy those design changes expected to have comparable effects on in-
use fuel economy;
    (5) The test procedure change is required by EPA or is a change
initiated by EPA in its laboratory and is not a change implemented
solely by a manufacturer in its own laboratory.

gasoline or diesel (petroleum) fuel rounded to the nearest 0.01
miles/million BTU.
FEalt is the fuel economy [miles/gallon for liquid fuels
or miles/100 standard cubic feet for gaseous fuels] while operated
on the alternative fuel as determined in Sec.  600.113-08(a) and
(b);
FEpet is the fuel economy [miles/gallon] while operated

    (ii)(A) The net heating value for alcohol fuels shall be
premeasured using a test method which has been approved in advance by
the Administrator.
    (B) The density for alcohol fuels shall be premeasured using ASTM D
1298-85 (Reapproved 1990) ``Standard Practice for Density, Relative
Density (Specific Gravity), or API Gravity of Crude Petroleum and
Liquid Petroleum Products by Hydrometer Method'' (incorporated by
reference at Sec.  600.011-93).
    (iii) The net heating value and density of gasoline are to be
determined by the manufacturer in accordance with Sec.  600.113(f).

paragraphs (j)(2)(vi) and (vii) of this section.
    (1) Upon written request from a manufacturer, the Administrator
will determine and publish by written guidance an appropriate value of
F for each requested alternative fuel based on the Administrator's
assessment of real-world use of the alternative fuel. Such published
values would be available for any manufacturer to use. The
Administrator will periodically update these values upon written
request from a manufacturer.
    (2) The manufacturer may optionally submit to the Administrator its
own demonstration regarding the real-world use of the alternative fuel
in their vehicles and its own estimate of the appropriate value of F in
the equations in paragraphs (j)(2)(vi) and (vii) of this section.
Depending on the nature of the analytical approach, the manufacturer
could provide estimates of F that are model type specific or that are
generally applicable to the manufacturer's dual fuel fleet. The
manufacturer's analysis could include use of data gathered from on-
board sensors and computers, from dual fuel vehicles in fleets that are
centrally fueled, or from other sources. The analysis must be based on
sound statistical methodology and must account for analytical
uncertainty. Any approval by the Administrator will pertain to the use
of values of F for the model types specified by the manufacturer.

SUPPLEMENTARY INFORMATION: The information collected under the
requirements of FERC-547, ``Gas Pipeline Rates: Refund Report
Requirements'' (OMB No. 1902-0084), is used by the Commission to
implement the statutory refund provisions governed by sections 4, 5 and
16 of the Natural Gas Act (NGA).\1\ Sections 4 and 5 authorize the
Commission to order a refund, with interest, for any portion of a
natural gas company's increased rate or charge found to be unjust or
unreasonable. Refunds may also be instituted by a natural gas company
as a stipulation to a Commission-approved settlement agreement or a
provision under the company's tariff. Section 16 of the NGA authorizes
the Commission to prescribe rules and regulations necessary to
administer its refund mandates. The Commission's refund reporting
requirements are found in 18 CFR 154.501 and 154.502.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 717-717w.
---------------------------------------------------------------------------

    The Commission uses the data to monitor refunds owed by natural gas
companies to ensure that the flow-through of refunds owed by these
companies are made as expeditiously as possible and to assure that
refunds are made in compliance with the Commission's regulations.
    Action: The Commission is requesting a three-year extension of the
FERC-547 reporting requirements, with no changes.
    Burden Statement: The estimated annual public reporting burden for
FERC-547 is reduced from the estimate made three years ago due to a
reduction in the average number of filings received annually, from 60
in 2007, to 30 presently.

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

    The total estimated annual cost burden to respondents is $149,143
(2,250 hours/2,080 hours \2\ per year, times $137,874 \3\).
    The reporting burden includes the total time, effort, or financial
resources expended to generate, maintain, retain, disclose, or provide
the information including: (1) Reviewing instructions; (2) developing,
acquiring, installing, and utilizing technology and systems for the
purposes of collecting, validating, verifying, processing, maintaining,
disclosing, and providing information; (3) adjusting the existing ways
to comply with any previously applicable instructions and requirements;
(4) training personnel to respond to a collection of information; (5)
searching data sources; (6) completing and reviewing the collection of
information; and (7) transmitting or otherwise disclosing the
information.
    The estimate of cost for respondents is based upon salaries for
professional and clerical support, as well as direct and indirect
overhead costs. Direct costs include all costs directly attributable to
providing this information, such as administrative costs and the cost
for information technology. Indirect or overhead costs are costs
incurred by an organization in support of its mission. These costs
apply to activities which benefit the whole organization rather than
any one particular function or activity.
    Comments are invited on: (1) Whether the proposed collection of
information is necessary for the proper performance of the functions of
the Commission, including whether the information will have practical
utility; (2) the accuracy of the agency's estimate of the burden of the
proposed collection of information, including the validity of the
methodology and assumptions used; (3) ways to enhance the quality,
utility and clarity of the information to be collected; and (4) ways to
minimize the burden of the collection of information on those who are
to respond, including the use of appropriate automated, electronic,
mechanical, or other technological collection techniques or other forms
of information technology, e.g., permitting electronic submission of
responses.
