Supplemental Determination for
Renewable Fuels Produced Under the
Final RFS2 Program From Grain
Sorghum
Environmental Protection
Agency (EPA).
AGENCY:
ACTION:
Final rule.
EPA is issuing a supplemental
rule associated with the Renewable Fuel
Standard (RFS) program. This final rule
contains a lifecycle GHG analysis for
grain sorghum ethanol and a regulatory
determination that grain sorghum
ethanol qualifies as a renewable fuel
under the RFS Program. EPA’s analysis
indicates that ethanol made from grain
sorghum at dry mill facilities that use
natural gas for process energy meets the
lifecycle greenhouse gas emissions
reduction threshold of 20 percent
compared to the baseline petroleum fuel
it would replace, and therefore qualifies
as renewable fuel. It also contains our
regulatory determination that grain
sorghum ethanol produced at dry mill
facilities using specified forms of biogas
for both process energy and most
electricity production, has lifecycle
GHG emission reductions of more than
50 percent compared to the baseline
petroleum fuel it would replace, and
that such grain sorghum ethanol
qualifies as an advanced biofuel under
the RFS Program.

II. Analysis of Lifecycle Greenhouse
Gas Emissions
A. Methodology
pmangrum on DSK3VPTVN1PROD with
1. Scope of Analysis
On March 26, 2010, the
Environmental Protection Agency (EPA)
published changes to the Renewable
Fuel Standard program regulations as
required by 2007 amendments to CAA
211(o). This rulemaking is commonly
referred to as the ‘‘March, 2010 RFS2
final rule’’. As part of the March, 2010
RFS2 final rule we analyzed various
categories of biofuels to determine
whether the complete lifecycle GHG
emissions (domestic and international)
associated with the production,
distribution, and use of those fuels meet
minimum lifecycle greenhouse gas
reduction thresholds as specified in
CAA section 211(o) (i.e., 60% for
cellulosic biofuel, 50% for biomassbased diesel and advanced biofuel, and
20% for other renewable fuels). Our
final rule focused our lifecycle analyses
on fuels that were anticipated to
contribute relatively large volumes of
renewable fuel by 2022 and thus did not
cover all fuels that either are
contributing or could potentially
contribute to the program. In the
preamble to the final rule, EPA
indicated that it had not completed the
GHG emissions impact analysis for
several specific biofuel production
pathways but that this work would be
completed through supplemental
rulemaking processes. Since the final
rule was issued, we have continued to
examine several additional pathways.
On June 12, 2012, we published a
Notice of Data Availability Concerning
Renewable Fuels Produced From Grain
Sorghum Under the RFS Program (see
77 FR 34915). In that notice of data
availability, we provided an opportunity
for comment on EPA’s analysis of grain
sorghum used as a feedstock to produce
ethanol under the RFS program. Today’s
final rule describes our lifecycle
analysis of ethanol made from grain
sorghum (‘‘grain sorghum ethanol’’) and
presents our determination that grain
sorghum ethanol qualifies as renewable
fuel (20% lifecycle GHG reduction as
compared to baseline fuel) or as
advanced biofuel (50% lifecycle GHG
reduction as compared to baseline fuel)
if produced pursuant to specified
pathways. The modeling approach EPA
used in this analysis is the same general
approach used in the March, 2010 RFS2
final rule for lifecycle analyses of other
biofuels.1 The March, 2010 RFS2 final

2. Models Used
The analysis EPA has prepared for
grain sorghum ethanol uses the same set
of models that was used for the March,
2010 RFS2 final rule. To estimate the
domestic agricultural impacts presented
in the following sections, we used the
Forestry and Agricultural Sector
Optimization Model (FASOM)
developed by Texas A&M University. To
estimate the international agricultural
sector impacts, we used the Food and
Agricultural Policy and Research
Institute international models as
maintained by the Center for
Agricultural and Rural Development
(FAPRI–CARD) at Iowa State University.
For more information on the FASOM
and FAPRI–CARD models, refer to the
March, 2010 RFS2 final rule preamble
(75 FR 14670) or the March, 2010 RFS2
final rule Regulatory Impact Analysis
(RIA).2 The models require a number of
inputs that are specific to the pathway
being analyzed, including projected
yields of feedstock per acre planted,
projected fertilizer use, and energy use
in feedstock processing and fuel
production. The docket includes
detailed information on model inputs,
assumptions, calculations, and the
results of our assessment of the lifecycle
GHG emissions performance of
specified pathways for producing grain
sorghum ethanol.
3. Scenarios Modeled for Impacts of
Increased Demand for Grain Sorghum
To assess the impacts of an increase
in renewable fuel volume from
business-as-usual (what is likely to have
occurred without the RFS biofuel
mandates) to levels required by the
statute, we established a control case
and other cases for a number of biofuels
analyzed for the March, 2010 RFS2 final
rule. The control case included a
projection of renewable fuel volumes
that might be used to comply with the
RFS renewable fuel volume mandates in
full. The other cases are designed such
that the only difference between a given
case and the control case is the volume
of an individual biofuel, all other
volumes remaining the same. In the
March, 2010 RFS2 final rule, for each
individual biofuel, we analyzed the

incremental GHG emission impacts of
increasing the volume of that fuel to the
total mix of biofuels needed to meet the
EISA requirements.
For the analysis of grain sorghum
ethanol, we applied the same
methodology as in the March, 2010
RFS2 final rule. In this case, we
compared a scenario that included 200
million gallons of grain sorghum
ethanol to another scenario that
included 300 million gallons of grain
sorghum ethanol, ensuring that all other
renewable fuel volumes are equal
between the two scenarios. The scenario
with 200 million gallons of grain
sorghum ethanol will henceforth be
referred to as the ‘‘control case,’’ which
was developed to account for the
current production of grain sorghum
ethanol which is approximately 200
million gallons per year (see Chapter 1
of the March, 2010 RFS2 final rule RIA).
All other volumes for each individual
biofuel in this new control case remain
identical to the control case used in the
March, 2010 RFS2 final rule. The
scenario with 300 million gallons of
grain sorghum ethanol will be referred
to as the ‘‘grain sorghum’’ case. For the
grain sorghum case, our modeling
assumes approximately 300 million
gallons of sorghum ethanol would be
consumed in the United States in 2022.
The modeled scenario includes 2.06
billion lbs of grain sorghum to be used
to produce the additional 100 million
gallons of ethanol in 2022.
Our volume scenario of
approximately 200 million gallons of
grain sorghum ethanol in the control
case, and 300 million gallons in the
grain sorghum case in 2022, is based on
several factors including historical
volumes of grain sorghum ethanol
production, potential feedstock
availability and other competitive uses
(e.g., animal feed or exports). Our
assessment is described further in the
inputs and assumptions document that
is available through the docket (EPA
2011). Based in part on consultation
with experts at the United States
Department of Agriculture (USDA) and
industry representatives, we believe that
these volumes are reasonable for the
purposes of evaluating the impacts of
producing additional volumes of
ethanol from grain sorghum.
The FASOM and FAPRI–CARD
models, described above, project how
much grain sorghum will be supplied to
ethanol production from a combination
of increased production, decreases in
others uses (e.g., animal feed), and
decreases in exports, in going from the
control case to the grain sorghum case.

Federal Register / Vol. 77, No. 242 / Monday, December 17, 2012 / Rules and Regulations
4. Model Modifications
Based on information from industry
stakeholders, as well as in consultation
with USDA, both the FASOM and
FAPRI–CARD models assume perfect
substitution in the use of grain sorghum
and corn in the animal feed market in
the U.S. Therefore, when more grain
sorghum is used for ethanol production,
grain sorghum that is used in feed
decreases. Either additional corn or
additional sorghum production will be
used in the feed market to make up for
this decrease, depending upon the
relative cost of additional production.
This assumption is based on
conversations with industry and the
USDA, reflecting the primary use of
sorghum in the U.S. as animal feed, just
like corn. We received a number of
comments in response to our Notice of
Data Availability (NODA) for Renewable
Fuels Produced from Grain Sorghum
Under the RFS Program (77 FR 34915,
June 12, 2012) that support this
assumption.
The United States is one of the largest
producers and exporters of grain
sorghum. Two other large producers of
grain sorghum, India and Nigeria, do not
actively participate in the global trade
market for sorghum. Rather, all grain
sorghum in those two countries is
produced for domestic consumption.
Therefore, as the U.S. diverts some of its
exports of grain sorghum for the
purposes of ethanol production, we
would expect close to no reaction in the
production levels of grain sorghum in
India and Nigeria. Historical data on
prices, production, and exports from
USDA, FAOSTAT (the Statistics
Division of the Food and Agriculture
Organization of the U.N.), and FAPRI
support this assumption.3 We received
several comments in response to our
NODA that supported our proposed
assumption that production of grain
sorghum in India and Nigeria is not
impacted by changes in production and
trade of grain sorghum in the U.S. It
should be noted that India and Nigeria
are unique in this behavior in regards to
grain sorghum production, consumption
and trade. Other countries are expected
to vary their harvested area in response
to changes in U.S. grain sorghum
exports, which can be seen in Table II–
4 below.
B. Results
As we did for our analysis of other
feedstocks in the March, 2010 RFS2
final rule, we assessed what the GHG
emissions impacts would be from the
use of additional volumes of sorghum
for biofuel production. The information
provided in this section discusses the
assumptions and outputs of the analysis
using the FASOM and FAPRI–CARD
agro-economic models to determine
changes in the agricultural and livestock
markets. These results from FASOM and
FAPRI–CARD are then used to
determine the GHG emissions impacts
due to land use change and other
factors. Finally, we include our analysis
of the GHG emissions associated with
different processing pathways and how
the choice of technologies affect the
lifecycle GHG emissions associated with
grain sorghum ethanol.
As discussed in the March, 2010 RFS2
final rule and the accompanying peer
review, there are inherent challenges in
reconciling the results from two
different models. However, using two
models provides a more complete and
robust analysis than either model would
be able to provide alone. We have
attempted to align as many of the key
assumptions as possible to get a
consistent set of modeling results
although there are structural differences
in the models that account for some of
the differences in the model results. For
example, since FASOM is a long-term
dynamic optimization model, short-term
spikes are smoothed out over the five
year reporting period. In comparison,
the FAPRI–CARD model captures
annual fluctuations that may include
short-term supply and demand
responses. In addition, some of the
discrepancies may be attributed to
different underlying assumptions
pertaining to elasticities of supply and
demand for different commodities.
These differences, in turn, affect
projections of imports and exports,
acreage shifting, and total consumption
and production of various commodities.
1. Agro-Economic Impacts
EPA received no significant
comments regarding the results from the
FASOM and FAPRI–CARD models, nor
did EPA receive recommendations that
the models be re-run with different
assumptions. Therefore, the results from
these two models are identical to those
results presented and discussed in the
NODA. For more detailed results, please
refer to the NODA. Given the
importance of the land use change
results for our emissions analysis we are
presenting these identical results for
reference in this final rule.
In the FASOM model, the increase in
grain sorghum area harvested is
relatively modest, at an additional 4
thousand acres, due to the fact that
demand for grain sorghum for use in
ethanol production is being met by a
shift of grain sorghum from one existing
use (in the animal feed market) to
another (ethanol production). Meeting
the subsequent gap in supply of animal
feed, however, leads to an increase of
141 thousand corn acres in 2022.
Another way to describe this interaction
is that it is relatively more profitable to
take grain sorghum out of the feed
market for ethanol production and grow
more corn, than it is to simply grow
more grain sorghum for ethanol
production. Due to the increased
demand for corn production and
harvested area, soybean harvested area
would decrease by 105 thousand acres
(corn and soybeans often compete for
land). Other crops in the U.S., such as
wheat, hay, and rice, are projected to
have a net increase of 53 thousand
acres.

Federal Register / Vol. 77, No. 242 / Monday, December 17, 2012 / Rules and Regulations
As demand for grain sorghum
increases for ethanol production in the
U.S., the FAPRI–CARD model estimates
that the U.S. will decrease exports of
grain sorghum and increase exports of
corn to partially satisfy the gap of
having less grain sorghum in the
worldwide feed market. This
combination of impacts on the world
trade of grain sorghum and corn has
effects both on major importers, as well
as on other major exporters. For
example, Mexico, one of the largest
importers of grain sorghum, decreases
its imports of grain sorghum and
increases its imports of corn. Brazil also
contributes more corn to the global
market by increasing its exports.
The change in trade patterns directly
impacts the amount of production and
harvested crop area around the world.
Harvested crop area for grain sorghum is
not only predicted to increase in the
U.S., but also in Mexico (7.8 thousand
acres) and other parts of the world.
Worldwide grain sorghum harvested
area outside of the U.S. would increase
by 39.3 thousand acres. Similarly, the
increase in the demand for corn would
lead to an increase of 36.8 thousand
harvested acres outside of the U.S.
While soybean harvested area would
decrease in the U.S., Brazil would
increase its soybean harvested area (18.4
thousand acres) to satisfy global
demand. Although worldwide soybean
74595
harvested area decreases by 11.7
thousand acres, non-U.S. harvested area
increases by 11.2 thousand acres.
Overall harvested crop area in other
countries also increase, particularly in
Brazil. Brazil’s total harvested area is
predicted to increase by 32.6 thousand
acres by 2022. This is mostly comprised
of an increase in corn of 18.1 thousand
acres, and an increase in soybeans of
18.4 thousand acres, along with minor
changes in other crops. More details on
projected changes in world harvested
crop area in 2022 can be found below
in Table II–2, Table II–3, Table II–4, and

2. International Land Use Change
Emissions
pmangrum on DSK3VPTVN1PROD with
The methodology used in today’s
assessment of grain sorghum as an
ethanol feedstock is the same as that
used in the March 2010 RFS2 final rule
for analyses of other biofuel pathways.
However, we have updated some of the
data underlying the GHG emissions
from international land use changes;
therefore, we are providing additional
detail on these modifications in this
section.
In our analysis, GHG emissions per
acre of land conversion internationally
(i.e., outside of the United States) are
determined using the emissions factors
developed for the March 2010 RFS2
final rule, following IPCC guidelines. In
addition, estimated average forest
carbon stocks were updated based on a
new study which uses a more robust
and higher resolution analysis. For the
March 2010 RFS2 final rule,
international forest carbon stocks were
estimated from several data sources
each derived using a different
methodological approach. Two new
peer-reviewed analyses on forest carbon
stock estimation have been completed
since the release of the March 2010
RFS2 final rule, one for three
continental regions by Saatchi et al.4
and the other for the EU by Gallaun et

EPA’s Notice of Data Availability
Concerning Renewable Fuels Produced
From Palm Oil Under the RFS Program
(77 FR 4300, January 27, 2012). Forest
carbon stocks across the tropics are
important in our analysis of grain
sorghum ethanol because a significant
amount of the land use changes in the
scenarios modelled occur in tropical
regions such as Brazil. In the scenarios
modelled, there are also much smaller
amounts of land use change impacts in
the EU related to grain sorghum ethanol
production. In the interest of using the
best available data, we have
incorporated the improved forest carbon
stocks data in our analysis of lifecycle
GHG emissions related to grain sorghum
ethanol.
Preliminary results for Latin America
and Africa from Saatchi et al. were
incorporated into the March 2010 RFS2
final rule, but Asia results were not
included due to timing considerations.
The Saatchi et al. analysis is now
complete, and so the final map was used
to calculate updated area-weighted
average forest carbon stocks for the
entire area covered by the analysis
(Latin America, sub-Saharan Africa and
South and Southeast Asia). The Saatchi
et al. results represent a significant
improvement over previous estimates
because they incorporate data from
more than 4,000 ground inventory plots,
about 150,000 biomass values estimated
from forest heights measured by spaceborne light detection and ranging
(LIDAR), and a suite of optical and radar
satellite imagery products. Estimates are
spatially refined at 1-km grid cell
resolution and are directly comparable
across countries and regions.
In the March 2010 RFS2 final rule,
forest carbon stocks for the European
Union were estimated using a
combination of data from three different
sources. Issues with this ‘patchwork’
approach were that the biomass
estimates were not comparable across
countries due to the differences in
methodological approaches, and that
estimates were not spatially derived (or,

Gallaun et al. developed EU-wide maps
of above-ground biomass in forests
based on remote sensing and field
measurements. MODIS data were used
for the classification, and
comprehensive field measurement data
from national forest inventories for
nearly 100,000 locations from 16
countries were also used to develop the
final map. The map covers the whole
EU, the European Free Trade
Association countries, the Balkans,
Belarus, the Ukraine, Moldova,
Armenia, Azerbaijan, Georgia, and
Turkey.
For both data sources, Saatchi et al.
and Gallaun et al., we added
belowground biomass to reported
aboveground biomass values using an
equation in Mokany et al.6
In our analysis, forest stocks are
estimated for over 750 regions across
160 countries. For some regions the
carbon stocks increased as a result of the
updates and in others they declined. For
comparison, we ran our grain sorghum
analysis using the old forest carbon
stock values used in the March 2010
RFS2 final rule and with the updated
forest carbon values described above.
Using the updated forest carbon stocks
increased the land use change GHG
emissions related to grain sorghum
ethanol by approximately 1.2 kilograms
of carbon dioxide equivalent emissions
per million British thermal units of
grain sorghum ethanol (kgCO2e/
mmBtu). Table II–6 includes the

The NODA discussed how several
technologies and fuel choices affect
emissions. Process energy fuel choice
has a significant impact on emissions
from a sorghum ethanol plant.
Switching from natural gas to biogas
from landfills, waste treatment plants
and/or waste digesters, for example, was
shown to reduce lifecycle GHG
emissions by approximately 20
percentage points. Therefore, use of
such biogas provides a way for grain
sorghum ethanol plants to reduce their
GHG emissions. However, in order for
the biogas to count as a GHG reduction
mechanism under the grain sorghum
ethanol pathways discussed in this
rulemaking it has to come from
landfills, waste treatment plants, or
waste digesters. The reason for this is
that those sources of biogas are assumed
to have zero upstream GHG impacts.
We received comments on the GHG
emissions associated with the use of
biogas as a process energy source,
specifically for biogas from manure
digesters. Development and operation of
a manure digester system results in
fugitive methane and other emissions,
though their use also means emissions
associated with alternative manure
disposal methods are avoided. Putting
in place a manure digester and
capturing methane will result in a
change of emissions from the existing
disposal method. There is guidance
available for calculating these emission
changes.7 Based on one application of
this guidance, one commenter indicated
that the upstream GHG impacts of
biogas production from a manure
digester would be a net increase in GHG
emissions. Another commenter using
their own application of the guidance
indicated that there would be a net
reduction in upstream GHG emissions
from the use of biogas from a manure
digester.
The differences in net emission
estimates from manure digesters depend
upon the assumptions about the
alternative manure disposal methods. If
the alternative disposal methods would
not have resulted in significant
emissions (e.g., if no methane were
generated or if the methane generated
were captured and destroyed) then the
installation of a manure digester could

lead to an increase in emissions. On the
other hand, if there would have been
significant emissions from an alternative
disposal method that would be avoided,
then the installation of a manure
digester would result in a decrease in
net emissions. EPA’s approach for
projecting the net emissions from
manure digesters for the sorghum
lifecycle GHG calculations was to
assume effectively zero net emissions
from digester biogas. This assumption is
consistent with our treatment of biogas
emissions in previous RFS rulemakings.
Given the uncertainty in the range of
possible alternative manure disposal
emissions, we feel this approach is
reasonable. In order for biogas from
manure digesters to result in positive
net GHG emissions, the emissions from
the alternative disposal method would
have to be close to zero. This would
only be the case with limited types of
disposal in which the decomposition of
the manure was mainly aerobic and
does not result in methane emissions,
such as land application. Although the
majority of manure in the United States
is handled as a solid, producing little
CH4, the general trend in manure
management is one of increasing use of
liquid systems. The shift in manure
management practices is due in part to
a shift toward larger livestock facilities
which typically use liquid manure
management systems. Liquid systems
have higher potential CH4 emissions
than dry systems.8 Alternatively, the
existing disposal methods could have
emissions close to zero if they were
capturing methane emissions and
destroying them, which is not generally
happening in current practice.9 It is
possible that use of manure digesters
could provide a net GHG benefit as
compared to alternative disposal
methods. However, we also do not have
enough information to include a generic
GHG offset reduction for manure
digesters at this time. Assuming zero net

emissions for present purposes appears
reasonable given the range of
possibilities. We plan to seek comment
on the possible use of manure digester
offsets as part of a future rulemaking
and clarify their use for this and other
pathways in Table 1 to § 80.1426.
Interested parties using manure
digesters may also submit a petition
under the 40 CFR 80.1416 petition
process.
We also received comments to expand
the discussion to include ‘‘biomass
energy’’ that is not restricted to only
biogas in the context of a fuel source
from landfills, waste treatment plants,
and waste digesters. The comments
point to existing pathways in Table 1 to
§ 80.1426 that include the use of biogas
or biomass. We plan to clarify the
meaning of the term biomass through a
separate rulemaking and will consider
the comments of adding biomass as a
process energy source to the grain
sorghum ethanol pathway at that time.
In the interim, we believe it is preferable
to issue today’s rule identifying two
qualifying grain sorghum ethanol
pathways without delay. Doing so
allows producers using these pathways
the opportunity to generate RINs while
EPA evaluates adding a definition of
biomass as an energy source for use in
biofuel production.
Another factor that influences GHG
impacts from process energy use is the
percentage of DG that are dried. If a
plant is able to reduce the amount of DG
it dries, process energy use and GHG
emissions decrease. The impact of going
from 100% dry DG to 100% wet DG is
larger for natural gas plants
(approximately a 10% reduction in
overall GHG emissions relative to the
petroleum baseline) compared to biogas
plants because biogas plants already
have low emissions from process
energy.
The NODA also discussed how
production facilities that utilize
combined heat and power (CHP)
systems can also reduce GHG emissions
relative to less efficient system
configurations. The CHP system
configuration considered in the NODA
calculations were based on using a
boiler to power a turbine generator unit
that produces electricity, and using
waste heat to produce process steam.
PO 00000
Frm 00044
Fmt 4700

There are provisions in our regulations
stating that combined heat and power
(CHP), also known as cogeneration,
refers to industrial processes in which
waste heat from the production of
electricity is used for process energy in
the renewable fuel production facility.
Table 2 to § 80.1426 includes combined
heat and power such that, on a calendar
year basis, at least 90% of the thermal
energy associated with ethanol
production (including thermal energy
produced at the facility and that which
is derived from an off-site waste heat
supplier), exclusive of any thermal
energy used for the drying of distillers
grains and solubles, is used to produce
electricity prior to being used to meet
the process heat requirements of the
facility.
We received comments that these
current provisions only describe ‘‘top
cycle’’ (high pressure) CHP systems.
Commenters requested that we also
allow other types of CHP configurations
(e.g., ‘‘low pressure’’ CHP systems). EPA
recognizes that there are many different
types of CHP configurations and that
some types that do not fit our current
regulatory provisions could have similar
GHG reductions.
Although not exhaustive, Table II–7
shows the amount of process fuel and
electricity from the grid used at a grain
sorghum ethanol facility for the
different technology and fuel options in
terms of Btu/gal of ethanol produced.
The energy use at dry mill ethanol
plants was based on ASPEN models
developed by USDA and updated to
reflect changes in technology out to
2022 as described in the March 2010
RFS2 final rule Regulatory Impact
Analysis (RIA) Chapter 1. The work
done on grain ethanol production for
the March 2010 RFS2 final rule was
based on converting corn to ethanol.
Converting grain sorghum to ethanol
will result in slightly different energy
use based on difference in the grains
and how they are processed. The same
ASPEN USDA models used for corn
ethanol in the final rule were also
developed for grain sorghum ethanol.
Based on the numbers from USDA, a
sorghum ethanol plant uses 96.3% of
the thermal process energy of a corn
ethanol plant (3.7% less), and 99.3% of
the electrical energy (0.7% less).

As shown in Table II–7, the difference
between CHP and non-CHP plants is
reflected in their use of different
amounts of primary energy (natural gas
or biogas) and the amount of electricity
used from the grid. The difference in
electricity used from the grid is
independent of the quantity of dry DG.
Furthermore, as the GHG calculations
are based on the amount of fuel used
times an emission factor plus the
amount of electricity used from grid
times an emissions factor, the use of
CHP versus some other type of
electricity generation system only
matters for natural gas plants. Although
less biogas would be needed if CHP is
used versus standard electricity
generation using biogas, the GHG
emissions are the same since the
emission factor for biogas (when it
comes from landfills, waste treatment
plants and/or waste digesters) is zero.
Therefore, because the only advanced
biofuel pathway we are adopting today
for the production of grain sorghum
ethanol involves use of biogas for onsite electricity production, we do not
need to specify that CHP be used. We
have therefore modified the final rule to
instead specify that for the advanced
biofuel grain sorghum pathway, biogas
from landfills, waste treatment plants
and/or waste digesters must be used for
on-site electricity production, and we
have provided an allowance for a
certain amount of grid-purchased
electricity that would still be consistent
with a finding of 50% lifecycle GHG
reduction as compared to baseline fuel.
Any configuration of CHP, or a non-CHP
system, could be used for the on-site
generation of electricity using biogas.
We have also included conforming
changes to the regulatory registration,
recordkeeping and reporting
requirements, to require verification of
the amount of grid electricity used at
facilities using this pathway.
The conforming changes include
adding a new paragraph (f)(13) to
Section 80.1426 describing detailed
requirements for the purchase,
measurement and use of biogas and
electricity from the grid for facilities
using the advanced biofuel grain
sorghum pathway. We have also
amended Section 80.1450 describing
registration requirements for facilities
using the advanced biofuel grain
sorghum pathway. Sections 80.1451 and
80.1454 are also amended to specify
reporting and recordkeeping
requirements for this pathway.
The following Table II–8 shows the
mean lifecycle GHG reductions
compared to the baseline petroleum fuel
for a number of different grain sorghum
ethanol production technology
pathways including natural gas and
biogas fired plants. In the following
section, we provide detailed analysis of
the lifecycle GHG emissions for two
scenarios. The first is for a dry mill
grain sorghum ethanol plant that uses
natural gas for process energy; the
second is for a dry mill grain sorghum
ethanol plant that uses biogas for both
process energy and for on-site electricity
production. These two scenarios were
chosen as examples of feasible
technology that a plant can use to
generate either conventional or
advanced fuel.

range of results shown in Figure II–1 is
based on our assessment of uncertainty
regarding the location and types of land
that may be impacted as well as the
GHG impacts associated with these land
use changes (see Section II.B.1. for
further information).
Table II–9 breaks down by stage the
lifecycle GHG emissions for a natural
gas fired grain sorghum ethanol plant
with 92% wet DG in 2022 and the
statutory 2005 gasoline baseline.11
Results are included using our midpoint estimate of land use change
emissions, as well as with the low and
high end of the 95% confidence
interval. Net agricultural emissions
include impacts related to changes in
crop inputs, such as fertilizer, energy
used in agriculture, livestock
production and other agricultural
changes in the scenarios modeled. The
fuel production stage includes
emissions from ethanol production
plants including drying 8% of the DG.
Fuel and feedstock transport includes
emissions from transporting bushels of
harvested grain sorghum from the farm
to the ethanol production facility, as
well as the emissions associated with
transporting ethanol from the
production facility to the fuel-blending
facility.
10 The 95% confidence interval around that
midpoint results in range of a 19% reduction to a

modeling) for grain sorghum ethanol
produced in a dry mill plant that
produces 0% wet DG and uses biogas
for process energy and for on-site
production of all electricity other than
0.15 kWh of grid electricity per gallon
of ethanol produced.
Figure II–2 shows the percent
difference between lifecycle GHG
emissions for the 2005 petroleum
gasoline fuel baseline and for 2022 grain
sorghum ethanol produced in a plant
that dries 100% of its DG, uses only
biogas as process energy and uses biogas
to produce all electricity used on site
except for 0.15 kWh of grid electricity
per gallon of ethanol produced.
Lifecycle GHG emissions equivalent to
the statutory gasoline fuel baseline are
represented on the graph by the zero on
the X-axis. The midpoint of the range of
results for this sorghum ethanol plant
configuration is a 52% reduction in
GHG emissions compared to the 2005
gasoline baseline.12 As in the case of
other biofuel pathways analyzed as part
of the March 2010 RFS2 final rule, the
range of results shown in Figure II–2 is

midpoint results in range of a 38% reduction to a
64% reduction compared to the 2005 gasoline fuel

includes emissions from transporting
bushels of harvested grain sorghum
from the farm to ethanol production
facility, as well as the emissions
associated with transporting ethanol
from the production facility to the fuelblending facility.

6. Other Ethanol Processing
Technologies
In the NODA we stated our intention
to address other broadly applicable
ethanol production technologies that
have the potential to reduce lifecycle
GHG emissions through a separate
rulemaking. In the NODA, we provided
a brief description of the use of
electricity that is derived from
renewable and non-carbon sources, such
as wind power, solar power,
hydropower, biogas or biomass as power
for process units and equipment, and
capturing and sequestering CO2
emissions from an ethanol plant. We
received comments supporting the use
of electricity that is derived from
renewable and non-carbon sources as
power for process units and equipment.
We also received comments supporting
the use of capturing and sequestering
CO2 emissions as part of the RFS2
program. Due to the range of issues
before us, and the fact that these issues
can pertain to more than just the
sorghum pathways, we intend to assess
these technologies in a separate action
and will consider at that time the
comments received in response to the
NODA and whether to broaden the
number of grain sorghum ethanol
pathways that may qualify for RIN
generation.
C. Consideration of Lifecycle Analysis
Results
1. Implications for Threshold
Determinations
As discussed above, EPA’s analysis
shows that, based on the mid-point of
the range of results, ethanol produced
from grain sorghum using biogas (from
landfills, waste treatment plants and/or
waste digesters) for process heat and to
produce all electricity used on-site,
other than 0.15 kWh of electricity from
the grid per gallon of ethanol produced
at a dry mill plant drying any amount
of DG would meet the 50 percent GHG
emissions reduction threshold needed
to qualify as an advanced biofuel (D–5
RINs). Grain sorghum ethanol meets the
20% lifecycle GHG emissions reduction
threshold for conventional biofuels (D–
6 RINs) when natural gas or biogas is
used for process energy at a dry mill
plant, regardless of how much DG is
dried. Therefore, Table 1 to Section
80.1426 is modified to add these new
pathways. Table II–11 illustrates how
these new pathways are included in the
existing table.

2. Consideration of Uncertainty
EPA’s threshold determinations for
grain sorghum ethanol are based on the
weight of evidence currently available.
For this pathway, the evidence
considered includes the mid-point
estimate as well as the range of results
based on statistical uncertainty and
sensitivity analyses conducted by the
Agency. EPA has weighed all of the
evidence, while placing the greatest
weight on the best-estimate value for the
scenarios analyzed.
VerDate Mar<15>2010
14:24 Dec 14, 2012
Jkt 229001
As part of our assessment of the grain
sorghum ethanol pathway, we have
identified key areas of uncertainty in
our analysis. Although there is
uncertainty in all portions of the
lifecycle modeling, we focused our
analysis on the factors that are the most
uncertain and have the biggest impact
on the results. The indirect international
emissions are the component of our
analysis with the highest level of
uncertainty. The type of land that is
converted internationally and the
emissions associated with this land

conversion are critical issues that have
a large impact on the GHG emissions
estimates.
Our analysis of land use change GHG
emissions includes an assessment of
uncertainty that focuses on two aspects
of indirect land use change—the types
of land converted and the GHG
emissions associated with different
types of land converted. These areas of
uncertainty were estimated statistically
using the Monte Carlo analysis
methodology developed for the March,

analysis of grain sorghum ethanol.

D. Other Comments Received
We received other comments that
suggested that if we are to calculate
certain indirect emissions and costs of
renewable fuels (e.g., land use, and
energy used for extraction), the same
should be included for petroleum fuels
that are being displaced. These
comments were similar to comments we
responded to in the March, 2010 final
RFS rule. Commenters did not provide
any new information or data that would
cause us to re-evaluate our methodology
that was described in more detail in the
March, 2010 RFS2 final rule. Therefore,
we are not making the suggested
modifications to our lifecycle analysis at
this time.
We also received comments regarding
the situation where a facility could be
characterized under two or more
separate pathways. For example a
facility co-processing different
feedstocks, like corn and sorghum, and
using two different process energy
sources simultaneously, like natural gas
and biogas with on-site electricity
production. The commenters asked if
different RINs could be produced based
on the different pathways represented
by the different feedstocks and process
energy sources used. In response, we
note that 40 CFR § 80.1426(f)(3)(i)–(vi)
addresses a number of options for the
generation of RINs when renewable fuel
production can be described by two or
more pathways. In situations not
covered by the regulations, parties may
submit a petition to EPA pursuant to
80.1416.
E. Summary
Based on our GHG lifecycle analysis
as discussed above, today’s rule
includes two pathways for ethanol
produced from grain sorghum
feedstocks. One pathway will allow the
generation of D code 6 RINs for grain
sorghum ethanol produced by a natural
gas or biogas fired dry mill facility that
dries any amount of DG. A second
pathway will allow producers of grain
sorghum ethanol to generate advanced
(D code 5) RINs if they use only biogas
for process energy and on-site electricity
production and use no more than 0.15
kWh of electricity from the grid per
gallon of ethanol produced. In both
cases, of course, RINs may only be

generated if the fuel meets other
definitional criteria for renewable fuel
(e.g., produced from renewable biomass
as defined in the March, 2010 RFS2
final rule regulations, and used to
reduce or replace the quantity of fossil
fuel present in transportation fuel,
heating oil or jet fuel). In order to
qualify for RIN generation, the fuel must
meet all other requirements specified in
the Clean Air Act and the RFS
regulations at 40 CFR part 80 Subpart
M. Parties that produce ethanol through
either pathway must do so in a matter
that is consistent with current
regulations. Failure to do so may result
in invalid RINs and penalties.
III. Statutory and Executive Order
Reviews
A. Executive Order 12866: Regulatory
Planning and Review and Executive
Order 13563: Improving Regulation and
Regulatory Review
This action is not a ‘‘significant
regulatory action’’ under the terms of
Executive Order 12866 (58 FR 51735,
October 4, 1993) and is therefore not
subject to review under Executive
Orders 12866 and 13563 (76 FR 3821,
January 21, 2011).
B. Paperwork Reduction Act
This action does not impose any new
information collection burden. The
corrections, clarifications, and
modifications to the March, 2010 RFS2
final regulations contained in this rule
are within the scope of the information
collection requirements submitted to the
Office of Management and Budget
(OMB) for the March, 2010 RFS2 final
regulations.
OMB has approved the information
collection requirements contained in the
existing regulations at 40 CFR part 80,
subpart M under the provisions of the
Paperwork Reduction Act, 44 U.S.C.
3501 et seq. and has assigned OMB
control numbers 2060–0637 and 2060–
0640. The OMB control numbers for
EPA’s regulations in 40 CFR are listed
in 40 CFR part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA)
generally requires an agency to prepare
a regulatory flexibility analysis of any
rule subject to notice and comment
rulemaking requirements under the
Administrative Procedure Act or any
other statute unless the agency certifies
that the rule will not have a significant
economic impact on a substantial
number of small entities. Small entities
include small businesses, small
organizations, and small governmental
jurisdictions.
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
For purposes of assessing the impacts
of today’s rule on small entities, small
entity is defined as: (1) A small business
as defined by the Small Business
Administration’s (SBA) regulations at 13
CFR 121.201; (2) a small governmental
jurisdiction that is a government of a
city, county, town, school district or
special district with a population of less
than 50,000; and (3) a small
organization that is any not-for-profit
enterprise which is independently
owned and operated and is not
dominant in its field.
After considering the economic
impacts of this action on small entities,
I certify that this rule will not have a
significant economic impact on a
substantial number of small entities.
This rule will not impose any new
requirements on small entities. Rather,
we expect that this rule may have a
positive impact on entities that would
now have the opportunity to generate
advanced RINs, where they may have
been unable to prior to this rule. The
relatively minor corrections and
modifications this rule makes to the
March, 2010 RFS2 final regulations do
not impact small entities.
D. Unfunded Mandates Reform Act
This rule does not contain a Federal
mandate that may result in expenditures
of $100 million or more for State, local,
and tribal governments, in the aggregate,
or the private sector in any one year. We
have determined that this action will
not result in expenditures of $100
million or more for the above parties
and thus, this rule is not subject to the
requirements of sections 202 or 205 of
UMRA.
This rule is also not subject to the
requirements of section 203 of UMRA
because it contains no regulatory
requirements that might significantly or
uniquely affect small governments. It
only applies to gasoline, diesel, and
renewable fuel producers, importers,
distributors and marketers.
E. Executive Order 13132: Federalism
This action does not have federalism
implications. It will not have substantial
direct effects on the States, on the
relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132. This action only
applies to gasoline, diesel, and
renewable fuel producers, importers,
distributors and marketers. Thus,
Executive Order 13132 does not apply
to this action.

Federal Register / Vol. 77, No. 242 / Monday, December 17, 2012 / Rules and Regulations
F. Executive Order 13175: Consultation
and Coordination With Indian Tribal
Governments
This rule does not have tribal
implications, as specified in Executive
Order 13175 (65 FR 67249, November 9,
2000). It applies to gasoline, diesel, and
renewable fuel producers, importers,
distributors and marketers. This action
does not impose any enforceable duties
on communities of Indian tribal
governments. Thus, Executive Order
13175 does not apply to this action.
G. Executive Order 13045: Protection of
Children From Environmental Health
Risks and Safety Risks
EPA interprets E.O. 13045 (62 FR
19885, April 23, 1997) as applying only
to those regulatory actions that concern
health or safety risks, such that the
analysis required under section 5–501 of
the E.O. has the potential to influence
the regulation. This action is not subject
to E.O. 13045 because it does not
establish an environmental standard
intended to mitigate health or safety
risks.
H. Executive Order 13211: Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use
‘‘This action is not subject to
Executive Order 13211 (66 FR 28355
(May 22, 2001)), because it is not a
significant regulatory action under
Executive Order 12866.’’
I. National Technology Transfer and
Advancement Act
Section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (‘‘NTTAA’’), Public Law
104–113, 12(d) (15 U.S.C. 272 note)
directs EPA to use voluntary consensus
standards in its regulatory activities
unless to do so would be inconsistent
with applicable law or otherwise
impractical. Voluntary consensus
standards are technical standards (e.g.,
materials specifications, test methods,
sampling procedures, and business
practices) that are developed or adopted
by voluntary consensus standards
bodies. NTTAA directs EPA to provide
Congress, through OMB, explanations
when the Agency decides not to use
available and applicable voluntary
consensus standards.
This action does not involve technical
standards. Therefore, EPA did not
consider the use of any voluntary
consensus standards.
J. Executive Order 12898: Federal
Actions To Address Environmental
Justice in Minority Populations and
Low-Income Populations
Executive Order (E.O.) 12898 (59 FR
7629 (Feb. 16, 1994)) establishes Federal
executive policy on environmental
justice. Its main provision directs
Federal agencies, to the greatest extent
practicable and permitted by law, to
make environmental justice part of their
mission by identifying and addressing,
as appropriate, disproportionately high
and adverse human health or
environmental effects of their programs,
policies, and activities on minority
populations and low-income
populations in the United States.
EPA has determined that this rule will
not have disproportionately high and
adverse human health or environmental
effects on minority or low-income
populations because it does not affect
the level of protection provided to
human health or the environment.
These amendments would not relax the
control measures on sources regulated
by the RFS regulations and therefore
would not cause emissions increases
from these sources.
K. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, to each House of the
Congress and to the Comptroller General
of the United States. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
EPA will submit a report containing this
rule and other required information to
the U.S. Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).
IV. Statutory Provisions and Legal
Authority
Statutory authority for the rule
finalized today can be found in section
211 of the Clean Air Act, 42 U.S.C.
7545. Additional support for today’s
rule comes from Section 301(a) of the
Clean Air Act, 42 U.S.C. 7414, 7542, and
7601(a).

ACTION: Final rule.
AGENCY:
This rule identifies
communities where the sale of flood
insurance has been authorized under
the National Flood Insurance Program
(NFIP) that are scheduled for
suspension on the effective dates listed
within this rule because of
noncompliance with the floodplain
management requirements of the
program. If the Federal Emergency
Management Agency (FEMA) receives
documentation that the community has
adopted the required floodplain
management measures prior to the
effective suspension date given in this
rule, the suspension will not occur and
a notice of this will be provided by
publication in the Federal Register on a
subsequent date. Also, information
identifying the current participation
status of a community can be obtained
from FEMA’s Community Status Book
(CSB). The CSB is available at https://

The NFIP
enables property owners to purchase
Federal flood insurance that is not
otherwise generally available from
private insurers. In return, communities
agree to adopt and administer local
floodplain management measures aimed
at protecting lives and new construction
from future flooding. Section 1315 of
the National Flood Insurance Act of
1968, as amended, 42 U.S.C. 4022,
prohibits the sale of NFIP flood
insurance unless an appropriate public
body adopts adequate floodplain
management measures with effective
enforcement measures. The
communities listed in this document no
longer meet that statutory requirement
for compliance with program
regulations, 44 CFR part 59.
Accordingly, the communities will be
suspended on the effective date in the
third column. As of that date, flood
insurance will no longer be available in
the community. We recognize that some
of these communities may adopt and
submit the required documentation of
legally enforceable floodplain
management measures after this rule is
published but prior to the actual
suspension date. These communities
will not be suspended and will continue
to be eligible for the sale of NFIP flood
insurance. A notice withdrawing the
suspension of such communities will be
published in the Federal Register.
In addition, FEMA publishes a Flood
Insurance Rate Map (FIRM) that
identifies the Special Flood Hazard
Areas (SFHAs) in these communities.
The date of the FIRM, if one has been
published, is indicated in the fourth
column of the table. No direct Federal
financial assistance (except assistance
pursuant to the Robert T. Stafford
Disaster Relief and Emergency
Assistance Act not in connection with a
flood) may be provided for construction
or acquisition of buildings in identified
SFHAs for communities not
participating in the NFIP and identified
for more than a year on FEMA’s initial
FIRM for the community as having
flood-prone areas (section 202(a) of the
Flood Disaster Protection Act of 1973,
42 U.S.C. 4106(a), as amended). This
prohibition against certain types of
Federal assistance becomes effective for
the communities listed on the date
shown in the last column. The
Administrator finds that notice and
public comment procedures under 5
U.S.C. 553(b), are impracticable and
unnecessary because communities listed

Supplemental Determination for Renewable Fuels Produced Under the
Final RFS2 Program From Grain Sorghum
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is issuing a supplemental rule associated with the
Renewable Fuel Standard (RFS) program. This final rule contains a
lifecycle GHG analysis for grain sorghum ethanol and a regulatory
determination that grain sorghum ethanol qualifies as a renewable fuel
under the RFS Program. EPA's analysis indicates that ethanol made from
grain sorghum at dry mill facilities that use natural gas for process
energy meets the lifecycle greenhouse gas emissions reduction threshold
of 20 percent compared to the baseline petroleum fuel it would replace,
and therefore qualifies as renewable fuel. It also contains our
regulatory determination that grain sorghum ethanol produced at dry
mill facilities using specified forms of biogas for both process energy
and most electricity production, has lifecycle GHG emission reductions
of more than 50 percent compared to the baseline petroleum fuel it
would replace, and that such grain sorghum ethanol qualifies as an
advanced biofuel under the RFS Program.
DATES: This final rule is effective on December 17, 2012.

II. Analysis of Lifecycle Greenhouse Gas Emissions
A. Methodology
1. Scope of Analysis
On March 26, 2010, the Environmental Protection Agency (EPA)
published changes to the Renewable Fuel Standard program regulations as
required by 2007 amendments to CAA 211(o). This rulemaking is commonly
referred to as the ``March, 2010 RFS2 final rule''. As part of the
March, 2010 RFS2 final rule we analyzed various categories of biofuels
to determine whether the complete lifecycle GHG emissions (domestic and
international) associated with the production, distribution, and use of
those fuels meet minimum lifecycle greenhouse gas reduction thresholds
as specified in CAA section 211(o) (i.e., 60% for cellulosic biofuel,
50% for biomass-based diesel and advanced biofuel, and 20% for other
renewable fuels). Our final rule focused our lifecycle analyses on
fuels that were anticipated to contribute relatively large volumes of
renewable fuel by 2022 and thus did not cover all fuels that either are
contributing or could potentially contribute to the program. In the
preamble to the final rule, EPA indicated that it had not completed the
GHG emissions impact analysis for several specific biofuel production
pathways but that this work would be completed through supplemental
rulemaking processes. Since the final rule was issued, we have
continued to examine several additional pathways. On June 12, 2012, we
published a Notice of Data Availability Concerning Renewable Fuels
Produced From Grain Sorghum Under the RFS Program (see 77 FR 34915). In
that notice of data availability, we provided an opportunity for
comment on EPA's analysis of grain sorghum used as a feedstock to
produce ethanol under the RFS program. Today's final rule describes our
lifecycle analysis of ethanol made from grain sorghum (``grain sorghum
ethanol'') and presents our determination that grain sorghum ethanol
qualifies as renewable fuel (20% lifecycle GHG reduction as compared to
baseline fuel) or as advanced biofuel (50% lifecycle GHG reduction as
compared to baseline fuel) if produced pursuant to specified pathways.
The modeling approach EPA used in this analysis is the same general
approach used in the March, 2010 RFS2 final rule for lifecycle analyses
of other biofuels.\1\ The March, 2010 RFS2 final rule preamble and
Regulatory Impact Analysis (RIA) provides further discussion of our
approach.

---------------------------------------------------------------------------
2. Models Used
The analysis EPA has prepared for grain sorghum ethanol uses the
same set of models that was used for the March, 2010 RFS2 final rule.
To estimate the domestic agricultural impacts presented in the
following sections, we used the Forestry and Agricultural Sector
Optimization Model (FASOM) developed by Texas A&M University. To
estimate the international agricultural sector impacts, we used the
Food and Agricultural Policy and Research Institute international
models as maintained by the Center for Agricultural and Rural
Development (FAPRI-CARD) at Iowa State University. For more information
on the FASOM and FAPRI-CARD models, refer to the March, 2010 RFS2 final
rule preamble (75 FR 14670) or the March, 2010 RFS2 final rule
Regulatory Impact Analysis (RIA).\2\ The models require a number of
inputs that are specific to the pathway being analyzed, including
projected yields of feedstock per acre planted, projected fertilizer
use, and energy use in feedstock processing and fuel production. The
docket includes detailed information on model inputs, assumptions,
calculations, and the results of our assessment of the lifecycle GHG
emissions performance of specified pathways for producing grain sorghum
ethanol.

---------------------------------------------------------------------------
3. Scenarios Modeled for Impacts of Increased Demand for Grain Sorghum
To assess the impacts of an increase in renewable fuel volume from
business-as-usual (what is likely to have occurred without the RFS
biofuel mandates) to levels required by the statute, we established a
control case and other cases for a number of biofuels analyzed for the
March, 2010 RFS2 final rule. The control case included a projection of
renewable fuel volumes that might be used to comply with the RFS
renewable fuel volume mandates in full. The other cases are designed
such that the only difference between a given case and the control case
is the volume of an individual biofuel, all other volumes remaining the
same. In the March, 2010 RFS2 final rule, for each individual biofuel,
we analyzed the incremental GHG emission impacts of increasing the
volume of that fuel to the total mix of biofuels needed to meet the
EISA requirements.
For the analysis of grain sorghum ethanol, we applied the same
methodology as in the March, 2010 RFS2 final rule. In this case, we
compared a scenario that included 200 million gallons of grain sorghum
ethanol to another scenario that included 300 million gallons of grain
sorghum ethanol, ensuring that all other renewable fuel volumes are
equal between the two scenarios. The scenario with 200 million gallons
of grain sorghum ethanol will henceforth be referred to as the
``control case,'' which was developed to account for the current
production of grain sorghum ethanol which is approximately 200 million
gallons per year (see Chapter 1 of the March, 2010 RFS2 final rule
RIA). All other volumes for each individual biofuel in this new control
case remain identical to the control case used in the March, 2010 RFS2
final rule. The scenario with 300 million gallons of grain sorghum
ethanol will be referred to as the ``grain sorghum'' case. For the
grain sorghum case, our modeling assumes approximately 300 million
gallons of sorghum ethanol would be consumed in the United States in
2022. The modeled scenario includes 2.06 billion lbs of grain sorghum
to be used to produce the additional 100 million gallons of ethanol in
2022.
Our volume scenario of approximately 200 million gallons of grain
sorghum ethanol in the control case, and 300 million gallons in the
grain sorghum case in 2022, is based on several factors including
historical volumes of grain sorghum ethanol production, potential
feedstock availability and other competitive uses (e.g., animal feed or
exports). Our assessment is described further in the inputs and
assumptions document that is available through the docket (EPA 2011).
Based in part on consultation with experts at the United States
Department of Agriculture (USDA) and industry representatives, we
believe that these volumes are reasonable for the purposes of
evaluating the impacts of producing additional volumes of ethanol from
grain sorghum.
The FASOM and FAPRI-CARD models, described above, project how much
grain sorghum will be supplied to ethanol production from a combination
of increased production, decreases in others uses (e.g., animal feed),
and decreases in exports, in going from the control case to the grain
sorghum case.
[[Page 74594]]
4. Model Modifications
Based on information from industry stakeholders, as well as in
consultation with USDA, both the FASOM and FAPRI-CARD models assume
perfect substitution in the use of grain sorghum and corn in the animal
feed market in the U.S. Therefore, when more grain sorghum is used for
ethanol production, grain sorghum that is used in feed decreases.
Either additional corn or additional sorghum production will be used in
the feed market to make up for this decrease, depending upon the
relative cost of additional production. This assumption is based on
conversations with industry and the USDA, reflecting the primary use of
sorghum in the U.S. as animal feed, just like corn. We received a
number of comments in response to our Notice of Data Availability
(NODA) for Renewable Fuels Produced from Grain Sorghum Under the RFS
Program (77 FR 34915, June 12, 2012) that support this assumption.
The United States is one of the largest producers and exporters of
grain sorghum. Two other large producers of grain sorghum, India and
Nigeria, do not actively participate in the global trade market for
sorghum. Rather, all grain sorghum in those two countries is produced
for domestic consumption. Therefore, as the U.S. diverts some of its
exports of grain sorghum for the purposes of ethanol production, we
would expect close to no reaction in the production levels of grain
sorghum in India and Nigeria. Historical data on prices, production,
and exports from USDA, FAOSTAT (the Statistics Division of the Food and
Agriculture Organization of the U.N.), and FAPRI support this
assumption.\3\ We received several comments in response to our NODA
that supported our proposed assumption that production of grain sorghum
in India and Nigeria is not impacted by changes in production and trade
of grain sorghum in the U.S. It should be noted that India and Nigeria
are unique in this behavior in regards to grain sorghum production,
consumption and trade. Other countries are expected to vary their
harvested area in response to changes in U.S. grain sorghum exports,
which can be seen in Table II-4 below.

B. Results
As we did for our analysis of other feedstocks in the March, 2010
RFS2 final rule, we assessed what the GHG emissions impacts would be
from the use of additional volumes of sorghum for biofuel production.
The information provided in this section discusses the assumptions and
outputs of the analysis using the FASOM and FAPRI-CARD agro-economic
models to determine changes in the agricultural and livestock markets.
These results from FASOM and FAPRI-CARD are then used to determine the
GHG emissions impacts due to land use change and other factors.
Finally, we include our analysis of the GHG emissions associated with
different processing pathways and how the choice of technologies affect
the lifecycle GHG emissions associated with grain sorghum ethanol.
As discussed in the March, 2010 RFS2 final rule and the
accompanying peer review, there are inherent challenges in reconciling
the results from two different models. However, using two models
provides a more complete and robust analysis than either model would be
able to provide alone. We have attempted to align as many of the key
assumptions as possible to get a consistent set of modeling results
although there are structural differences in the models that account
for some of the differences in the model results. For example, since
FASOM is a long-term dynamic optimization model, short-term spikes are
smoothed out over the five year reporting period. In comparison, the
FAPRI-CARD model captures annual fluctuations that may include short-
term supply and demand responses. In addition, some of the
discrepancies may be attributed to different underlying assumptions
pertaining to elasticities of supply and demand for different
commodities. These differences, in turn, affect projections of imports
and exports, acreage shifting, and total consumption and production of
various commodities.
1. Agro-Economic Impacts
EPA received no significant comments regarding the results from the
FASOM and FAPRI-CARD models, nor did EPA receive recommendations that
the models be re-run with different assumptions. Therefore, the results
from these two models are identical to those results presented and
discussed in the NODA. For more detailed results, please refer to the
NODA. Given the importance of the land use change results for our
emissions analysis we are presenting these identical results for
reference in this final rule.
In the FASOM model, the increase in grain sorghum area harvested is
relatively modest, at an additional 4 thousand acres, due to the fact
that demand for grain sorghum for use in ethanol production is being
met by a shift of grain sorghum from one existing use (in the animal
feed market) to another (ethanol production). Meeting the subsequent
gap in supply of animal feed, however, leads to an increase of 141
thousand corn acres in 2022. Another way to describe this interaction
is that it is relatively more profitable to take grain sorghum out of
the feed market for ethanol production and grow more corn, than it is
to simply grow more grain sorghum for ethanol production. Due to the
increased demand for corn production and harvested area, soybean
harvested area would decrease by 105 thousand acres (corn and soybeans
often compete for land). Other crops in the U.S., such as wheat, hay,
and rice, are projected to have a net increase of 53 thousand acres.

[[Page 74595]]
As demand for grain sorghum increases for ethanol production in the
U.S., the FAPRI-CARD model estimates that the U.S. will decrease
exports of grain sorghum and increase exports of corn to partially
satisfy the gap of having less grain sorghum in the worldwide feed
market. This combination of impacts on the world trade of grain sorghum
and corn has effects both on major importers, as well as on other major
exporters. For example, Mexico, one of the largest importers of grain
sorghum, decreases its imports of grain sorghum and increases its
imports of corn. Brazil also contributes more corn to the global market
by increasing its exports.
The change in trade patterns directly impacts the amount of
production and harvested crop area around the world. Harvested crop
area for grain sorghum is not only predicted to increase in the U.S.,
but also in Mexico (7.8 thousand acres) and other parts of the world.
Worldwide grain sorghum harvested area outside of the U.S. would
increase by 39.3 thousand acres. Similarly, the increase in the demand
for corn would lead to an increase of 36.8 thousand harvested acres
outside of the U.S. While soybean harvested area would decrease in the
U.S., Brazil would increase its soybean harvested area (18.4 thousand
acres) to satisfy global demand. Although worldwide soybean harvested
area decreases by 11.7 thousand acres, non-U.S. harvested area
increases by 11.2 thousand acres.
Overall harvested crop area in other countries also increase,
particularly in Brazil. Brazil's total harvested area is predicted to
increase by 32.6 thousand acres by 2022. This is mostly comprised of an
increase in corn of 18.1 thousand acres, and an increase in soybeans of
18.4 thousand acres, along with minor changes in other crops. More
details on projected changes in world harvested crop area in 2022 can
be found below in Table II-2, Table II-3, Table II-4, and Table II-5.

2. International Land Use Change Emissions
The methodology used in today's assessment of grain sorghum as an
ethanol feedstock is the same as that used in the March 2010 RFS2 final
rule for analyses of other biofuel pathways. However, we have updated
some of the data underlying the GHG emissions from international land
use changes; therefore, we are providing additional detail on these
modifications in this section.
In our analysis, GHG emissions per acre of land conversion
internationally (i.e., outside of the United States) are determined
using the emissions factors developed for the March 2010 RFS2 final
rule, following IPCC guidelines. In addition, estimated average forest
carbon stocks were updated based on a new study which uses a more
robust and higher resolution analysis. For the March 2010 RFS2 final
rule, international forest carbon stocks were estimated from several
data sources each derived using a different methodological approach.
Two new peer-reviewed analyses on forest carbon stock estimation have
been completed since the release of the March 2010 RFS2 final rule, one
for three continental regions by Saatchi et al.\4\ and the other for
the EU by Gallaun et al.\5\ We have updated our forest carbon stock
estimates based on these new studies because they represent significant
improvements as compared to the data used in the March 2010 RFS2 final
rule. These updated forest carbon stock estimates were previously used
in EPA's Notice of Data Availability Concerning Renewable Fuels
Produced From Palm Oil Under the RFS Program (77 FR 4300, January 27,
2012). Forest carbon stocks across the tropics are important in our
analysis of grain sorghum ethanol because a significant amount of the
land use changes in the scenarios modelled occur in tropical regions
such as Brazil. In the scenarios modelled, there are also much smaller
amounts of land use change impacts in the EU related to grain sorghum
ethanol production. In the interest of using the best available data,
we have incorporated the improved forest carbon stocks data in our
analysis of lifecycle GHG emissions related to grain sorghum ethanol.

measurements. Forest Ecology and Management 260: 252-261.
---------------------------------------------------------------------------
Preliminary results for Latin America and Africa from Saatchi et
al. were incorporated into the March 2010 RFS2 final rule, but Asia
results were not included due to timing considerations. The Saatchi et
al. analysis is now complete, and so the final map was used to
calculate updated area-weighted average forest carbon stocks for the
entire area covered by the analysis (Latin America, sub-Saharan Africa
and South and Southeast Asia). The Saatchi et al. results represent a
significant improvement over previous estimates because they
incorporate data from more than 4,000 ground inventory plots, about
150,000 biomass values estimated from forest heights measured by space-
borne light detection and ranging (LIDAR), and a suite of optical and
radar satellite imagery products. Estimates are spatially refined at 1-
km grid cell resolution and are directly comparable across countries
and regions.
In the March 2010 RFS2 final rule, forest carbon stocks for the
European Union were estimated using a combination of data from three
different sources. Issues with this `patchwork' approach were that the
biomass estimates were not comparable across countries due to the
differences in methodological approaches, and that estimates were not
spatially derived (or, the spatial data were not provided to EPA).
Since the release of the final rule, Gallaun et al. developed EU-wide
maps of above-ground biomass in forests based on remote sensing and
field measurements. MODIS data were used for the classification, and
comprehensive field measurement data from national forest inventories
for nearly 100,000 locations from 16 countries were also used to
develop the final map. The map covers the whole EU, the European Free
Trade Association countries, the Balkans, Belarus, the Ukraine,
Moldova, Armenia, Azerbaijan, Georgia, and Turkey.
For both data sources, Saatchi et al. and Gallaun et al., we added
belowground biomass to reported aboveground biomass values using an
equation in Mokany et al.\6\

---------------------------------------------------------------------------
In our analysis, forest stocks are estimated for over 750 regions
across 160 countries. For some regions the carbon stocks increased as a
result of the updates and in others they declined. For comparison, we
ran our grain sorghum analysis using the old forest carbon stock values
used in the March 2010 RFS2 final rule and with the updated forest
carbon values described above. Using the updated forest carbon stocks
increased the land use change GHG emissions related to grain sorghum
ethanol by approximately 1.2 kilograms of carbon dioxide equivalent
emissions per million British thermal units of grain sorghum ethanol
(kgCO2e/mmBtu). Table II-6 includes the international land
use change GHG emissions results for the scenarios modeled, in terms of
kgCO2e/mmBtu. International land use change GHG emissions
for grain sorghum are estimated at 30 kgCO2e/mmBtu.

3. Grain Sorghum Ethanol Processing
The dry milling process is the ethanol production process
considered here for producing ethanol from grain sorghum. In the dry
milling process, the grain sorghum is ground and fermented to produce
ethanol. The remaining distillers grains (DG) are then either left wet
if used in the near-term or dried for longer term use as animal feed.
For this analysis, the amount of grain sorghum used for ethanol
production as modeled by the FASOM and FAPRI-CARD models was based on
yield assumptions built into those two models. Specifically, the models
assume sorghum ethanol yields of 2.71 gallons per bushel for dry mill
plants (yields represents pure ethanol).
As per the analysis done in the March 2010 RFS2 final rule, the
energy consumed and emissions generated by a renewable fuel plant must
be allocated not only to the renewable fuel produced, but also to each
of the by-products. For grain sorghum ethanol production, this analysis
accounts for the DG co-product use directly in the FASOM and FAPRI-CARD
agricultural sector modeling described in the NODA. DG are considered a
replacement animal feed and thus reduce the need to make up for the
grain sorghum production that went into ethanol production. Since FASOM
takes the production and use of DG into account, no further allocation
was needed at the ethanol plant and all plant emissions are accounted
for there.
As described in the NODA, the GHG emissions from production of
ethanol from grain sorghum were calculated in the same way as other
fuels analyzed as part of the March 2010 RFS final rule. The GHG
emissions were calculated by multiplying the amount of the different
types of energy inputs at the grain sorghum ethanol plant (e.g.,
natural gas, coal, biogas, electricity) by emissions factors for
production and use of those energy sources.
The NODA described how purchased fuel and electricity use for grain
sorghum ethanol production was based on the energy use information for
corn ethanol production from the March 2010 RFS final rule analysis.
These numbers reflect future plant energy use to represent plants that
would be built to meet future requirements for increased renewable fuel
use, as opposed to current or historic data on energy used in ethanol
production. The numbers also reflect adjustments to account for the
fact that converting grain sorghum to ethanol will result in slightly
different energy use based on the difference in the grains and how they
are processed.
Process energy at the plant includes natural gas, coal, or biogas
used in boilers to produce steam, in dryers, in thermal oxidizers or
used in other production or process equipment. Process electricity is
used for running pumps, conveyers, fans, lights, and other electrical
equipment. Specifically related to the fuel production process,
electricity can be produced on-site or purchased/received from an off-
site supplier.
The emissions associated with energy used at grain sorghum ethanol
facilities, varies significantly among plants with respect to the
production process, type of fuel used (e.g., coal versus natural gas),
and whether electricity used at the facility comes from the grid or is
produced from low-GHG emissions fuels such as biogas from landfills,
waste treatment plants and/or waste digesters. Variation also exists
between the same type of plants using the same fuel source based on the
design of the production process such as the technology used to
separate the ethanol from the water, the extent to which the DG are
dried and whether other co-products are produced. Such different
pathways were considered for ethanol made from corn. Since for the most
part these same production processes are available for ethanol produced
from sorghum, our analyses considered a similar set of production
pathways for grain sorghum ethanol production. Our focus was to
differentiate among facilities based on key differences, namely the
type of plant, the type of fuel used and source of electricity.
For grain sorghum, we analyzed several combinations of different
process technologies and fuels to determine their impacts on lifecycle
GHG emissions. This section describes the different GHG impacts
associated with alternative processing technology and fuel options and
outlines specific process pathways that would be needed to meet
different GHG threshold requirements.
The NODA discussed how several technologies and fuel choices affect
emissions. Process energy fuel choice has a significant impact on
emissions from a sorghum ethanol plant. Switching from natural gas to
biogas from landfills, waste treatment plants and/or waste digesters,
for example, was shown to reduce lifecycle GHG emissions by
approximately 20 percentage points. Therefore, use of such biogas
provides a way for grain sorghum ethanol plants to reduce their GHG
emissions. However, in order for the biogas to count as a GHG reduction
mechanism under the grain sorghum ethanol pathways discussed in this
rulemaking it has to come from landfills, waste treatment plants, or
waste digesters. The reason for this is that those sources of biogas
are assumed to have zero upstream GHG impacts.
We received comments on the GHG emissions associated with the use
of biogas as a process energy source, specifically for biogas from
manure digesters. Development and operation of a manure digester system
results in fugitive methane and other emissions, though their use also
means emissions associated with alternative manure disposal methods are
avoided. Putting in place a manure digester and capturing methane will
result in a change of emissions from the existing disposal method.
There is guidance available for calculating these emission changes.\7\
Based on one application of this guidance, one commenter indicated that
the upstream GHG impacts of biogas production from a manure digester
would be a net increase in GHG emissions. Another commenter using their
own application of the guidance indicated that there would be a net
reduction in upstream GHG emissions from the use of biogas from a
manure digester.
---------------------------------------------------------------------------

Performance of Anaerobic Digestion Systems for Livestock Manures,''

Program, Prepared by: Eastern Research Group, Inc., March 2011, and

Methodology for Project Type: Managing Manure with Biogas Recovery
Systems,'' Climate Protection Partnerships Division/Climate Change
Division, Office of Atmospheric Programs, U.S. Environmental
Protection Agency, August 2008, Version 1.3.
---------------------------------------------------------------------------
The differences in net emission estimates from manure digesters
depend upon the assumptions about the alternative manure disposal
methods. If the alternative disposal methods would not have resulted in
significant emissions (e.g., if no methane were generated or if the
methane generated were captured and destroyed) then the installation of
a manure digester could
[[Page 74598]]
lead to an increase in emissions. On the other hand, if there would
have been significant emissions from an alternative disposal method
that would be avoided, then the installation of a manure digester would
result in a decrease in net emissions. EPA's approach for projecting
the net emissions from manure digesters for the sorghum lifecycle GHG
calculations was to assume effectively zero net emissions from digester
biogas. This assumption is consistent with our treatment of biogas
emissions in previous RFS rulemakings.
Given the uncertainty in the range of possible alternative manure
disposal emissions, we feel this approach is reasonable. In order for
biogas from manure digesters to result in positive net GHG emissions,
the emissions from the alternative disposal method would have to be
close to zero. This would only be the case with limited types of
disposal in which the decomposition of the manure was mainly aerobic
and does not result in methane emissions, such as land application.
Although the majority of manure in the United States is handled as a
solid, producing little CH4, the general trend in manure management is
one of increasing use of liquid systems. The shift in manure management
practices is due in part to a shift toward larger livestock facilities
which typically use liquid manure management systems. Liquid systems
have higher potential CH4 emissions than dry systems.\8\ Alternatively,
the existing disposal methods could have emissions close to zero if
they were capturing methane emissions and destroying them, which is not
generally happening in current practice.\9\ It is possible that use of
manure digesters could provide a net GHG benefit as compared to
alternative disposal methods. However, we also do not have enough
information to include a generic GHG offset reduction for manure
digesters at this time. Assuming zero net emissions for present
purposes appears reasonable given the range of possibilities. We plan
to seek comment on the possible use of manure digester offsets as part
of a future rulemaking and clarify their use for this and other
pathways in Table 1 to Sec. 80.1426. Interested parties using manure
digesters may also submit a petition under the 40 CFR 80.1416 petition
process.

\9\ Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-
2010, U.S. EPA Annex 3 Section 3.10, the emissions factors used in
calculating methane emissions from manure management do not include
methane capture. EPA is not aware of any current or planned
regulations that would require methane capture and destruction from
existing manure management activities.
---------------------------------------------------------------------------
We also received comments to expand the discussion to include
``biomass energy'' that is not restricted to only biogas in the context
of a fuel source from landfills, waste treatment plants, and waste
digesters. The comments point to existing pathways in Table 1 to Sec.
80.1426 that include the use of biogas or biomass. We plan to clarify
the meaning of the term biomass through a separate rulemaking and will
consider the comments of adding biomass as a process energy source to
the grain sorghum ethanol pathway at that time. In the interim, we
believe it is preferable to issue today's rule identifying two
qualifying grain sorghum ethanol pathways without delay. Doing so
allows producers using these pathways the opportunity to generate RINs
while EPA evaluates adding a definition of biomass as an energy source
for use in biofuel production.
Another factor that influences GHG impacts from process energy use
is the percentage of DG that are dried. If a plant is able to reduce
the amount of DG it dries, process energy use and GHG emissions
decrease. The impact of going from 100% dry DG to 100% wet DG is larger
for natural gas plants (approximately a 10% reduction in overall GHG
emissions relative to the petroleum baseline) compared to biogas plants
because biogas plants already have low emissions from process energy.
The NODA also discussed how production facilities that utilize
combined heat and power (CHP) systems can also reduce GHG emissions
relative to less efficient system configurations. The CHP system
configuration considered in the NODA calculations were based on using a
boiler to power a turbine generator unit that produces electricity, and
using waste heat to produce process steam. There are provisions in our
regulations stating that combined heat and power (CHP), also known as
cogeneration, refers to industrial processes in which waste heat from
the production of electricity is used for process energy in the
renewable fuel production facility. Table 2 to Sec. 80.1426 includes
combined heat and power such that, on a calendar year basis, at least
90% of the thermal energy associated with ethanol production (including
thermal energy produced at the facility and that which is derived from
an off-site waste heat supplier), exclusive of any thermal energy used
for the drying of distillers grains and solubles, is used to produce
electricity prior to being used to meet the process heat requirements
of the facility.
We received comments that these current provisions only describe
``top cycle'' (high pressure) CHP systems. Commenters requested that we
also allow other types of CHP configurations (e.g., ``low pressure''
CHP systems). EPA recognizes that there are many different types of CHP
configurations and that some types that do not fit our current
regulatory provisions could have similar GHG reductions.
Although not exhaustive, Table II-7 shows the amount of process
fuel and electricity from the grid used at a grain sorghum ethanol
facility for the different technology and fuel options in terms of Btu/
gal of ethanol produced.
The energy use at dry mill ethanol plants was based on ASPEN models
developed by USDA and updated to reflect changes in technology out to
2022 as described in the March 2010 RFS2 final rule Regulatory Impact
Analysis (RIA) Chapter 1. The work done on grain ethanol production for
the March 2010 RFS2 final rule was based on converting corn to ethanol.
Converting grain sorghum to ethanol will result in slightly different
energy use based on difference in the grains and how they are
processed. The same ASPEN USDA models used for corn ethanol in the
final rule were also developed for grain sorghum ethanol. Based on the
numbers from USDA, a sorghum ethanol plant uses 96.3% of the thermal
process energy of a corn ethanol plant (3.7% less), and 99.3% of the
electrical energy (0.7% less).

----------------------------------------------------------------------------------------------------------------
As shown in Table II-7, the difference between CHP and non-CHP
plants is reflected in their use of different amounts of primary energy
(natural gas or biogas) and the amount of electricity used from the
grid. The difference in electricity used from the grid is independent
of the quantity of dry DG. Furthermore, as the GHG calculations are
based on the amount of fuel used times an emission factor plus the
amount of electricity used from grid times an emissions factor, the use
of CHP versus some other type of electricity generation system only
matters for natural gas plants. Although less biogas would be needed if
CHP is used versus standard electricity generation using biogas, the
GHG emissions are the same since the emission factor for biogas (when
it comes from landfills, waste treatment plants and/or waste digesters)
is zero. Therefore, because the only advanced biofuel pathway we are
adopting today for the production of grain sorghum ethanol involves use
of biogas for on-site electricity production, we do not need to specify
that CHP be used. We have therefore modified the final rule to instead
specify that for the advanced biofuel grain sorghum pathway, biogas
from landfills, waste treatment plants and/or waste digesters must be
used for on-site electricity production, and we have provided an
allowance for a certain amount of grid-purchased electricity that would
still be consistent with a finding of 50% lifecycle GHG reduction as
compared to baseline fuel. Any configuration of CHP, or a non-CHP
system, could be used for the on-site generation of electricity using
biogas. We have also included conforming changes to the regulatory
registration, recordkeeping and reporting requirements, to require
verification of the amount of grid electricity used at facilities using
this pathway.
The conforming changes include adding a new paragraph (f)(13) to
Section 80.1426 describing detailed requirements for the purchase,
measurement and use of biogas and electricity from the grid for
facilities using the advanced biofuel grain sorghum pathway. We have
also amended Section 80.1450 describing registration requirements for
facilities using the advanced biofuel grain sorghum pathway. Sections
80.1451 and 80.1454 are also amended to specify reporting and
recordkeeping requirements for this pathway.
The following Table II-8 shows the mean lifecycle GHG reductions
compared to the baseline petroleum fuel for a number of different grain
sorghum ethanol production technology pathways including natural gas
and biogas fired plants. In the following section, we provide detailed
analysis of the lifecycle GHG emissions for two scenarios. The first is
for a dry mill grain sorghum ethanol plant that uses natural gas for
process energy; the second is for a dry mill grain sorghum ethanol
plant that uses biogas for both process energy and for on-site
electricity production. These two scenarios were chosen as examples of
feasible technology that a plant can use to generate either
conventional or advanced fuel.

The docket for this final rule provides more details on our key
model inputs and assumptions (e.g., crop yields, biofuel conversion
yields, and agricultural energy use). These inputs and assumptions are
based on our analysis of peer-reviewed literature and consideration of
recommendations of experts from within the grain sorghum and ethanol
industries, USDA, and academic institutions.
4. Results of Lifecycle Analysis for Ethanol From Grain Sorghum (Using
Dry Mill Natural Gas)
Consistent with our approach for analyzing other pathways, our
analysis for grain sorghum ethanol includes a mid-point estimate as
well as a range of possible lifecycle GHG emission results based on
uncertainty analysis conducted by the Agency. The graph below (Figure
II-1) depicts the results of our analysis (including the uncertainty in
our land use change modeling) for grain sorghum ethanol produced in a
plant that uses natural gas and produces the current industry average
of 92% wet DG.
Lifecycle GHG emissions equivalent to the statutory gasoline fuel
baseline are represented on the graph by the zero on the X-axis. The
midpoint of the range of results is a 32% reduction in GHG emissions
compared to the 2005 gasoline baseline.\10\ As in the case of other
biofuel pathways analyzed as part of the March 2010 RFS2 final rule,
the range of results shown in Figure II-1 is based on our assessment of
uncertainty regarding the location and types of land that may be
impacted as well as the GHG impacts associated with these land use
changes (see Section II.B.1. for further information).
---------------------------------------------------------------------------
\10\ The 95% confidence interval around that midpoint results in
range of a 19% reduction to a 44% reduction compared to the 2005
gasoline fuel baseline.

Table II-9 breaks down by stage the lifecycle GHG emissions for a
natural gas fired grain sorghum ethanol plant with 92% wet DG in 2022
and the statutory 2005 gasoline baseline.\11\ Results are included
using our mid-point estimate of land use change emissions, as well as
with the low and high end of the 95% confidence interval. Net
agricultural emissions include impacts related to changes in crop
inputs, such as fertilizer, energy used in agriculture, livestock
production and other agricultural changes in the scenarios modeled. The
fuel production stage includes emissions from ethanol production plants
including drying 8% of the DG. Fuel and feedstock transport includes
emissions from transporting bushels of harvested grain sorghum from the
farm to the ethanol production facility, as well as the emissions
associated with transporting ethanol from the production facility to
the fuel-blending facility.

electricity other than 0.15 kWh of grid electricity per gallon of
ethanol produced.
Figure II-2 shows the percent difference between lifecycle GHG
emissions for the 2005 petroleum gasoline fuel baseline and for 2022
grain sorghum ethanol produced in a plant that dries 100% of its DG,
uses only biogas as process energy and uses biogas to produce all
electricity used on site except for 0.15 kWh of grid electricity per
gallon of ethanol produced. Lifecycle GHG emissions equivalent to the
statutory gasoline fuel baseline are represented on the graph by the
zero on the X-axis. The midpoint of the range of results for this
sorghum ethanol plant configuration is a 52% reduction in GHG emissions
compared to the 2005 gasoline baseline.\12\ As in the case of other
biofuel pathways analyzed as part of the March 2010 RFS2 final rule,
the range of results shown in Figure II-2 is based on our assessment of
uncertainty regarding the location and types of land that may be
impacted as well as the GHG impacts associated with these land use
changes (see Section II.B.1). These results justify our determination
that sorghum ethanol produced in dry mill plants that dry any amount of
DG and use only biogas (from landfills, waste treatment plants and/or
waste digesters) for process energy and production of electricity used
on site, other than 0.15 kWh of electricity from the grid per gallon of
ethanol produced, meet the 50% lifecycle GHG reduction threshold
required for the generation of advanced renewable fuel RINs.
---------------------------------------------------------------------------
\12\ The 95% confidence interval around that midpoint results in
range of a 38% reduction to a 64% reduction compared to the 2005
gasoline fuel baseline.

agricultural changes in the scenarios modeled. Emissions from fuel
production include emissions from ethanol production and drying 100% of
the DG. Fuel and feedstock transport includes emissions from
transporting bushels of harvested grain sorghum from the farm to
ethanol production facility, as well as the emissions associated with
transporting ethanol from the production facility to the fuel-blending

6. Other Ethanol Processing Technologies
In the NODA we stated our intention to address other broadly
applicable ethanol production technologies that have the potential to
reduce lifecycle GHG emissions through a separate rulemaking. In the
NODA, we provided a brief description of the use of electricity that is
derived from renewable and non-carbon sources, such as wind power,
solar power, hydropower, biogas or biomass as power for process units
and equipment, and capturing and sequestering CO2 emissions
from an ethanol plant. We received comments supporting the use of
electricity that is derived from renewable and non-carbon sources as
power for process units and equipment. We also received comments
supporting the use of capturing and sequestering CO2
emissions as part of the RFS2 program. Due to the range of issues
before us, and the fact that these issues can pertain to more than just
the sorghum pathways, we intend to assess these technologies in a
separate action and will consider at that time the comments received in
response to the NODA and whether to broaden the number of grain sorghum
ethanol pathways that may qualify for RIN generation.
C. Consideration of Lifecycle Analysis Results
1. Implications for Threshold Determinations
As discussed above, EPA's analysis shows that, based on the mid-
point of the range of results, ethanol produced from grain sorghum
using biogas (from landfills, waste treatment plants and/or waste
digesters) for process heat and to produce all electricity used on-
site, other than 0.15 kWh of electricity from the grid per gallon of
ethanol produced at a dry mill plant drying any amount of DG would meet
the 50 percent GHG emissions reduction threshold needed to qualify as
an advanced biofuel (D-5 RINs). Grain sorghum ethanol meets the 20%
lifecycle GHG emissions reduction threshold for conventional biofuels
(D-6 RINs) when natural gas or biogas is used for process energy at a
dry mill plant, regardless of how much DG is dried. Therefore, Table 1
to Section 80.1426 is modified to add these new pathways. Table II-11
illustrates how these new pathways are included in the existing table.
Table II-11--Pathways and Applicable D Codes for Grain Sorghum Ethanol
----------------------------------------------------------------------------------------------------------------
Production process
Fuel type Feedstock requirements D-Code
----------------------------------------------------------------------------------------------------------------
Ethanol............................... Grain Sorghum............ Dry mill process using biogas 6
from landfills, waste
treatment plants, and waste
digesters, and/or natural
gas, for process energy.
Ethanol............................... Grain Sorghum............ Dry mill process, using only 5
biogas from landfills, waste
treatment plants, and waste
digesters for process energy
and for on-site production
of all electricity used at
the site other than up to
0.15 kWh of electricity from
the grid per gallon of
ethanol produced.
----------------------------------------------------------------------------------------------------------------
2. Consideration of Uncertainty
EPA's threshold determinations for grain sorghum ethanol are based
on the weight of evidence currently available. For this pathway, the
evidence considered includes the mid-point estimate as well as the
range of results based on statistical uncertainty and sensitivity
analyses conducted by the Agency. EPA has weighed all of the evidence,
while placing the greatest weight on the best-estimate value for the
scenarios analyzed.
As part of our assessment of the grain sorghum ethanol pathway, we
have identified key areas of uncertainty in our analysis. Although
there is uncertainty in all portions of the lifecycle modeling, we
focused our analysis on the factors that are the most uncertain and
have the biggest impact on the results. The indirect international
emissions are the component of our analysis with the highest level of
uncertainty. The type of land that is converted internationally and the
emissions associated with this land conversion are critical issues that
have a large impact on the GHG emissions estimates.
Our analysis of land use change GHG emissions includes an
assessment of uncertainty that focuses on two aspects of indirect land
use change--the types of land converted and the GHG emissions
associated with different types of land converted. These areas of
uncertainty were estimated statistically using the Monte Carlo analysis
methodology developed for the March,
[[Page 74604]]
2010 RFS2 final rule.\14\ Figure II-1 and Figure II-2 show the results
of our statistical uncertainty assessment.
---------------------------------------------------------------------------
\14\ The Monte Carlo analysis is described in EPA (2010a),
Section 2.4.4.2.8.
---------------------------------------------------------------------------
The docket for this final rule provides more details on all aspects
of our analysis of grain sorghum ethanol.
D. Other Comments Received
We received other comments that suggested that if we are to
calculate certain indirect emissions and costs of renewable fuels
(e.g., land use, and energy used for extraction), the same should be
included for petroleum fuels that are being displaced. These comments
were similar to comments we responded to in the March, 2010 final RFS
rule. Commenters did not provide any new information or data that would
cause us to re-evaluate our methodology that was described in more
detail in the March, 2010 RFS2 final rule. Therefore, we are not making
the suggested modifications to our lifecycle analysis at this time.
We also received comments regarding the situation where a facility
could be characterized under two or more separate pathways. For example
a facility co-processing different feedstocks, like corn and sorghum,
and using two different process energy sources simultaneously, like
natural gas and biogas with on-site electricity production. The
commenters asked if different RINs could be produced based on the
different pathways represented by the different feedstocks and process
energy sources used. In response, we note that 40 CFR Sec.
80.1426(f)(3)(i)-(vi) addresses a number of options for the generation
of RINs when renewable fuel production can be described by two or more
pathways. In situations not covered by the regulations, parties may
submit a petition to EPA pursuant to 80.1416.
E. Summary
Based on our GHG lifecycle analysis as discussed above, today's
rule includes two pathways for ethanol produced from grain sorghum
feedstocks. One pathway will allow the generation of D code 6 RINs for
grain sorghum ethanol produced by a natural gas or biogas fired dry
mill facility that dries any amount of DG. A second pathway will allow
producers of grain sorghum ethanol to generate advanced (D code 5) RINs
if they use only biogas for process energy and on-site electricity
production and use no more than 0.15 kWh of electricity from the grid
per gallon of ethanol produced. In both cases, of course, RINs may only
be generated if the fuel meets other definitional criteria for
renewable fuel (e.g., produced from renewable biomass as defined in the
March, 2010 RFS2 final rule regulations, and used to reduce or replace
the quantity of fossil fuel present in transportation fuel, heating oil
or jet fuel). In order to qualify for RIN generation, the fuel must
meet all other requirements specified in the Clean Air Act and the RFS
regulations at 40 CFR part 80 Subpart M. Parties that produce ethanol
through either pathway must do so in a matter that is consistent with
current regulations. Failure to do so may result in invalid RINs and
penalties.
III. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a ``significant regulatory action'' under the
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is
therefore not subject to review under Executive Orders 12866 and 13563
(76 FR 3821, January 21, 2011).
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
The corrections, clarifications, and modifications to the March, 2010
RFS2 final regulations contained in this rule are within the scope of
the information collection requirements submitted to the Office of
Management and Budget (OMB) for the March, 2010 RFS2 final regulations.
OMB has approved the information collection requirements contained
in the existing regulations at 40 CFR part 80, subpart M under the
provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and
has assigned OMB control numbers 2060-0637 and 2060-0640. The OMB
control numbers for EPA's regulations in 40 CFR are listed in 40 CFR
part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act (RFA) generally requires an agency
to prepare a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements under the Administrative
Procedure Act or any other statute unless the agency certifies that the
rule will not have a significant economic impact on a substantial
number of small entities. Small entities include small businesses,
small organizations, and small governmental jurisdictions.
For purposes of assessing the impacts of today's rule on small
entities, small entity is defined as: (1) A small business as defined
by the Small Business Administration's (SBA) regulations at 13 CFR
121.201; (2) a small governmental jurisdiction that is a government of
a city, county, town, school district or special district with a
population of less than 50,000; and (3) a small organization that is
any not-for-profit enterprise which is independently owned and operated
and is not dominant in its field.
After considering the economic impacts of this action on small
entities, I certify that this rule will not have a significant economic
impact on a substantial number of small entities. This rule will not
impose any new requirements on small entities. Rather, we expect that
this rule may have a positive impact on entities that would now have
the opportunity to generate advanced RINs, where they may have been
unable to prior to this rule. The relatively minor corrections and
modifications this rule makes to the March, 2010 RFS2 final regulations
do not impact small entities.
D. Unfunded Mandates Reform Act
This rule does not contain a Federal mandate that may result in
expenditures of $100 million or more for State, local, and tribal
governments, in the aggregate, or the private sector in any one year.
We have determined that this action will not result in expenditures of
$100 million or more for the above parties and thus, this rule is not
subject to the requirements of sections 202 or 205 of UMRA.
This rule is also not subject to the requirements of section 203 of
UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments. It only applies to
gasoline, diesel, and renewable fuel producers, importers, distributors
and marketers.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government, as
specified in Executive Order 13132. This action only applies to
gasoline, diesel, and renewable fuel producers, importers, distributors
and marketers. Thus, Executive Order 13132 does not apply to this
action.
[[Page 74605]]
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This rule does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). It applies to
gasoline, diesel, and renewable fuel producers, importers, distributors
and marketers. This action does not impose any enforceable duties on
communities of Indian tribal governments. Thus, Executive Order 13175
does not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
EPA interprets E.O. 13045 (62 FR 19885, April 23, 1997) as applying
only to those regulatory actions that concern health or safety risks,
such that the analysis required under section 5-501 of the E.O. has the
potential to influence the regulation. This action is not subject to
E.O. 13045 because it does not establish an environmental standard
intended to mitigate health or safety risks.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
``This action is not subject to Executive Order 13211 (66 FR 28355
(May 22, 2001)), because it is not a significant regulatory action
under Executive Order 12866.''
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note)
directs EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. NTTAA directs EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards.
This action does not involve technical standards. Therefore, EPA
did not consider the use of any voluntary consensus standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order (E.O.) 12898 (59 FR 7629 (Feb. 16, 1994))
establishes Federal executive policy on environmental justice. Its main
provision directs Federal agencies, to the greatest extent practicable
and permitted by law, to make environmental justice part of their
mission by identifying and addressing, as appropriate,
disproportionately high and adverse human health or environmental
effects of their programs, policies, and activities on minority
populations and low-income populations in the United States.
EPA has determined that this rule will not have disproportionately
high and adverse human health or environmental effects on minority or
low-income populations because it does not affect the level of
protection provided to human health or the environment. These
amendments would not relax the control measures on sources regulated by
the RFS regulations and therefore would not cause emissions increases
from these sources.
K. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. A major rule cannot take effect until 60 days after it
is published in the Federal Register. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of the rule the Federal Register.
This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).
IV. Statutory Provisions and Legal Authority
Statutory authority for the rule finalized today can be found in
section 211 of the Clean Air Act, 42 U.S.C. 7545. Additional support
for today's rule comes from Section 301(a) of the Clean Air Act, 42
U.S.C. 7414, 7542, and 7601(a).
