IV. Statutory and Executive Order 
Reviews 
Under the Clean Air Act, the 
Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this proposed action merely proposes to approve state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: 
•Is not a ‘‘significant regulatory 
action’’ subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); 
•Is not an Executive Order 13771 (82 
FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866; 
•Does not impose an information 
collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 
•Is certified as not having a 
significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); 
•Does not contain any unfunded 
mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); 
•Does not have Federalism 
implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); 
•Is not an economically significant 
regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); 
•Is not a significant regulatory action 
subject to Executive Order 13211 (66 FR 28355, May 22, 2001); 
•Is not subject to requirements of 
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and 
•Does not provide the EPA with the 
discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). 
In addition, the SIP is not approved to 
apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : In this proposed rule, the 
Environmental Protection Agency (EPA) is providing an opportunity to comment on an analysis of the lifecycle greenhouse gas (GHG) emissions associated with certain biofuels that are produced from grain sorghum oil extracted at dry mill ethanol plants at any point downstream from sorghum grinding, also known as distiller sorghum oil. EPA seeks comment on its proposed assessment that using distillers sorghum oil as feedstock results in no significant agricultural sector GHG emissions; and that biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process, would meet the lifecycle GHG emissions reduction threshold of 50 percent required for advanced biofuels, and biomass-based diesel under the Renewable Fuel Standard program. Based on these analyses, EPA is proposing to amend the RFS program regulations to define the term ‘‘distillers sorghum oil’’. We also propose to add to the regulations approved pathways from the production of biodiesel and heating oil from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process.

B. What action is the Agency taking? 
EPA is proposing to amend the RFS 
program regulations to define the term ‘‘distillers sorghum oil’’ as oil from grain sorghum that is extracted at a dry mill ethanol plant at any location downstream of grinding the grain sorghum kernel, provided that the grain 
sorghum is converted to ethanol, the oil is rendered unfit for food uses without further refining, and the distillers grains resulting from the dry mill and oil extraction processes are marketable as animal feed. We also propose to add to Table 1 to 80.1426(f), approved pathways from the production of biodiesel and heating oil from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and liquefied petroleum gas (LPG) produced from distillers sorghum oil via a hydrotreating process. Alternatively, or in addition, EPA may consider the comments it receives in response to this document in evaluating facility-specific pathway petitions submitted pursuant to 40 CFR 80.1416 that propose using distillers sorghum oil to make biofuel. C. What is the Agency’s authority for 
taking this action? 
Statutory authority for this action 
comes from Clean Air Act sections 114, 208, 211, and 301. 
II. Public Participation 
EPA will not hold a public hearing on 
this matter unless a request is received

III. Introduction 
Section 211(o) of the Clean Air Act

2A baseline volume of renewable fuel produced 
from facilities that commenced construction on or 
before December 19, 2007, and which completed construction by December 19, 2010 without an 18- month hiatus in construction, is exempt from the minimum 20 percent GHG reduction requirement that otherwise applies to renewable fuel. In addition, a baseline volume of ethanol from facilities that commenced construction after December 19, 2007, and on or before December 31, 2009, qualifies for the same exemption if construction was completed within 36 months without an 18-month hiatus in construction; the facility was fired with natural gas, biomass, or any combination thereof, at all times the facility operated between December 19, 2007 and December 31, 2009; and the baseline volume continues to be produced through processes fired with natural gas, biomass, or any combination thereof. 
3Please see information on Pathways I and 
Pathways II in 40 CFR part 80 subpart M, and in the Federal Register at 78 FR 14190 (March 5, 2013) 
and 79 FR 42128 (July 18, 2014). More information on these can be found at: https://www.epa.gov/ renewable-fuel-standard-program/final-rule- identify-additional-fuel-pathways-under-renewable- fuel and https://www.epa.gov/renewable-fuel- 
standard-program/renewable-fuel-pathways-ii-final- rule-identify-additional-fuel. 4As defined in the RFS regulations at 40 CFR 
80.1401, biomass-based diesel excludes renewable fuel that is co-processed with petroleum. Such fuel may qualify as advanced biofuel if it meets the 50 percent GHG reduction threshold.

Continued fuel. Non-exempt2renewable fuels must 
achieve at least a 20 percent reduction 
in lifecycle GHG emissions as compared to a 2005 petroleum baseline. Advanced biofuel and biomass-based diesel must achieve at least a 50 percent reduction, and cellulosic biofuel must achieve at least a 60 percent reduction. 
In addition to the lifecycle GHG 
reduction requirements, renewable identification numbers (RINs) may only be generated if the fuel meets the other definitional criteria for renewable fuel (e.g., produced from renewable biomass 
as defined in the regulations, and used to reduce or replace the quantity of fossil fuel present in transportation fuel, heating oil, or jet fuel) in CAA section 211(o) and the RFS regulations at 40 CFR part 80 subpart M. 
Since the formation of the RFS 
program, EPA has periodically promulgated rules to add new pathways to the regulations.
3In addition, EPA has 
approved facility-specific pathways through the petition process in 40 CFR 80.1416. There are three critical components of approved fuel pathways under the RFS program: (1) Fuel type; (2) feedstock; and (3) production process. Each pathway is associated with a specific ‘‘D code’’ depending on whether the fuel meets the requirements for renewable fuel, advanced fuel, cellulosic fuel, or biomass-based diesel. 
EPA’s lifecycle analyses are used to 
assess the overall GHG emissions of a fuel throughout each stage of its production and use. The results of these analyses, considering uncertainty and the weight of available evidence, are used to determine whether a fuel meets the necessary GHG reductions required under the CAA. Lifecycle analysis includes an assessment of emissions 
related to the full fuel lifecycle, including feedstock production, feedstock transportation, fuel production, fuel transportation and distribution, and tailpipe emissions. Per the CAA definition of lifecycle GHG emissions, EPA’s lifecycle analyses also include an assessment of significant indirect emissions, such as those from land use changes and agricultural sector impacts. 
EPA received a petition from the 
National Sorghum Producers (NSP), submitted under partial claims of confidential business information (CBI), requesting that EPA evaluate the GHG emissions associated with biofuels produced using grain sorghum oil derived from dry mill ethanol production as a feedstock, and that EPA provide a determination of the renewable fuel categories, if any, for which such biofuels may be eligible. In this action, EPA is proposing to amend the RFS program regulations to define the term ‘‘distillers sorghum oil’’ as oil from grain sorghum that is extracted at a dry mill ethanol plant at any location downstream of grinding the grain sorghum kernel, provided that the grain sorghum is converted to ethanol, the oil is rendered unfit for food uses without further refining, and the distillers grains resulting from the dry mill and oil extraction processes are marketable as animal feed. We also propose to add to Table 1 to 40 CFR 80.1426(f), approved pathways from the production of biodiesel and heating oil from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel, heating oil, naphtha, and LPG produced from distillers sorghum oil via a hydrotreating process. Alternatively, or in addition, EPA may consider the comments it receives in response to this document in evaluating facility-specific pathway petitions submitted pursuant to 40 CFR 80.1416 that propose using distillers sorghum oil to make biofuel. 
This preamble describes EPA’s 
analysis of the GHG emissions associated with distillers sorghum oil when used to produce specified biofuels. The analysis considers a scenario where distillers sorghum oil is extracted from distillers grains with solubles (DGS) at dry mill plants that produce ethanol from grain sorghum and where the remaining reduced-oil DGS co-product is used as animal feed. The distillers sorghum oil is then used as a feedstock for conversion into certain biofuels. As described in Section IV of this preamble, we estimate that the lifecycle GHG emissions associated with 
the production of biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and 
renewable diesel, jet fuel, naphtha, and LPG, produced from distillers sorghum oil via a hydrotreating process, are approximately 80 percent less than the lifecycle GHG emissions associated with the baseline petroleum fuels they would replace. Based on these results, we propose to find that these biofuels would meet the 50 percent GHG reduction threshold required for advanced biofuel and biomass-based diesel. We also anticipate that heating oil produced through transesterification or hydrotreating from distillers sorghum oil would meet the 50 percent GHG emission reduction threshold required for advanced biofuel and biomass-based diesel.
4EPA is seeking public comment 
on its analyses of the lifecycle GHG emissions related to biofuels produced from distillers sorghum oil. 
IV. Analysis of GHG Emissions 
Associated With Production of Biofuels From Distillers Sorghum Oil 
A. Overview of Distillers Sorghum Oil 
Dry mill ethanol plants grind and 
ferment grain sorghum, produce ethanol 
from the fermented grain sorghum starch, and also produce a DGS co- product (made of non-fermentable solids, solubles syrup, and sorghum oil) that is sold as a type of livestock feed. A portion of the oil that would otherwise reside in the DGS can be extracted at the ethanol plant, typically through gravimetric methods. At dry mill ethanol plants, sorghum oil is recovered through methods nearly identical to that of corn oil extracted from DGS, and corn and sorghum oil extraction can occur at the same facilities. 
EPA has approved pathways for the 
production of ethanol from grain sorghum made through a dry mill process as qualifying for renewable fuel (D code 6) RINs, and in some cases advanced biofuel (D code 5) RINs, depending on process energy sources used during production.
5However, the 
regulations do not currently include pathways for the production of other biofuels from grain sorghum. According to the U.S. Department of Agriculture 
(USDA), the largest regions for grain sorghum production in the United States are located in Texas, Oklahoma, and Kansas.

DC, pg 329. Data for reduced-oil Sorghum DDGS was calculated by National Sorghum Producers using the ratio of (1) corn DDGS, between 6 to 9 percent Oil; and (2) corn DDGS, less than 4 percent oil from Nutrient Requirements of Swine, 2012 National Academies Press, Washington, DC, pp. 266 and 267. 
12‘‘Summary of Net Energy Impacts of Reduced- 
Oil Sorghum Dried Distillers Grains with Solubles (DDGS) on Livestock,’’ Air Docket EPA–HQ–OAR– 2017–0655. of grain sorghum grown, or 120 million 
bushels a year, goes towards ethanol production.
7For comparison, in recent 
years over 5,200 million bushels of corn have been used for ethanol production annually.
8Distillers sorghum oil is still 
a relatively niche product, and the NSP petition anticipates a potential of 12 to 21 million ethanol-equivalent gallons of fuel to be produced from the oil per year. 
We propose to define distillers 
sorghum oil to mean oil recovered at a point downstream of where a dry mill grain sorghum ethanol plant grinds the grain sorghum, provided that the grain sorghum is converted to ethanol, the oil is rendered unfit for food uses without further refining, and the distillers grains resulting from the dry mill and oil extraction processes are marketable as animal feed. So long as these criteria are met, a variety of recovery methods could be implemented. For example, this would include recovery of sorghum oil before fermentation from the slurry or from liquefaction tanks. It would also include recovery of sorghum oil after fermentation from the thin stillage and/ or DGS. Further, it would also include recovery of sorghum oil by a third-party from DGS produced by a dry mill sorghum ethanol plant. 
B. Analysis of Lifecycle GHG Emissions 
EPA evaluated the GHG emissions 
associated with using distillers sorghum 
oil as a biofuel feedstock based on information provided by the petitioner and other available data sources. GHG emissions include emissions from production and transport of distillers sorghum oil; the processing of the oil into biofuel; transport of the biofuel from the production facility to the fuel- blender; and, ultimately the use of the biofuel by the end consumer. The methodology EPA used for this analysis is generally the same approach used for the March 2010 RFS rule for lifecycle analyses of several other biofuel feedstocks, such as distillers corn oil and yellow grease.
9We believe that applying the same methodology for 
these feedstocks is appropriate given similarities in how these feedstocks are produced, transported and processed into biofuel. These similarities are explained further in this section. 
EPA’s lifecycle analyses include 
upstream emissions, which include the significant direct and indirect GHG emissions (including such emissions from land use changes) associated with producing a feedstock and transporting 
it to the processing facility. All of the upstream emissions were calculated and taken into account in EPA’s evaluation of the lifecycle GHG emissions associated with grain sorghum ethanol.
10Based on our analysis, 
producing distillers sorghum oil at a dry mill ethanol plant converting grain sorghum to ethanol, and using the extracted sorghum oil as a biofuel feedstock does not result in additional upstream emissions, compared to the upstream emissions that have already been calculated and attributed to grain sorghum ethanol. Further, based on our analysis, the production of distillers sorghum oil does not significantly impact the upstream emissions associated with grain sorghum ethanol. While producing distillers sorghum oil may impact livestock markets, through the effects of de-oiling DGS, we discuss in the next section why, based on the data we have reviewed, we do not anticipate this to cause any significant indirect impacts. We welcome comments on this data and analysis. 
1. Livestock Sector Impacts 
During a typical dry mill ethanol 
production process, DGS are produced. 
These DGS are then used as animal feed, thereby displacing feed crops and the GHG emissions associated with growing and transporting those feed crops. When distillers sorghum oil is produced, DGS continue to be created with reduced oil content. A significant portion of this analysis focuses on reviewing how reduced-oil DGS compare to full-oil DGS in terms of feed values and displacement of other feeds. 
Chemically, full-oil and reduced-oil 
sorghum DGS share similar compositions, primarily made up of crude protein, fat, and natural and acid detergent fibers. Where the two products differ most significantly is in their acid detergent fiber and fat concentrations. Table IV.1 shows the key nutrients that make up dried full-oil 
and reduced-oil DGS.

The difference in fat values is 
important as crude fat concentrations impact net energy uptake by the livestock. A memorandum to the docket shows the total net energy profiles by livestock of full-oil and reduced-oil sorghum DGS.
12Should fat content not 
be at sufficient levels, livestock producers might need to add nutrients or other types of feed to meet appropriate nutritional targets. This is reflected in the ‘‘displacement rate’’ of a DGS, which indicates how much weight a pound of distillers grain can replace of another feed. A lower displacement rate for a reduced-oil distillers grain as compared to a full-oil distillers grain could result in additional GHG emissions as it suggests that additional feed is required. In the case of reduced-oil sorghum DGS, we believe that it is unlikely that additional feed will be needed to backfill for the extracted oil.

swine, ‘‘increased concentrations of free fatty acids have a negative impact on

Free fatty acids are a class of acids that 
form part of a lipid molecule. Full-oil DGS typically contain higher levels of free fatty acids and thus may have a negative impact on the fat digestion of poultry and swine. This supports the conclusion that while the fat content may be lower for reduced-oil DGS, feeding values of this product should not be worse than full-oil DGS for poultry and swine. 
For dairy, there are also benefits from 
feeding reduced-oil DGS as compared to full-oil DGS. Research on dairy cows shows that reduced-oil DGS produce a lessened likelihood of the onset of milk fat depression.
14Milk fat depression 
occurs when milk fat is reduced by 0.2 percent or more.15If milk fat depression 
occurs over the long term, a decline in overall milk production may occur as well as worsened health conditions of the herd. High fat diets have been linked with this condition and have been shown to worsen the rumen environment of dairy cattle.
16Therefore, 
dairy producers seek to avoid high fat diets. Given the benefits of reduced-oil DGS over full-oil DGS for milk fat production, it is expected that reduced- oil DGS will be preferred over full-oil DGS by dairy producers and that displacement rates will be no worse than those of full-oil DGS. 
An impact on displacement rates may 
occur when reduced-oil instead of full- 
oil DGS are used for beef cattle, which has the ability to digest additional fat. 
Table IV.2 shows the displacement ratios for the livestock sectors where dried DGS (DDGS) are used. In this table, for instance, 1 pound of reduced- oil DDGS fed to beef cattle displaces 1.173 pounds of corn. A pound of full- oil and reduced-oil DDGS also displace equal portions (0.056 pounds) of urea. Urea is a non-protein nitrogen compound that is typically fed to cattle for aiding the production of protein by rumen microbes.
17These values show 
that for dairy, swine, and poultry, reduced-oil DDGS replace the same amounts of alternative feed despite containing less oil.

We anticipate that sorghum oil 
producers will seek to sell reduced-oil 
DGS to poultry, swine, and dairy cow producers, as these markets allow them to obtain a higher value for their product. Dairy cattle producers may be willing to pay a premium for reduced- oil distillers grains, as data suggests lower oil DGs improve milk production. 
Sales of reduced-oil DGS to the beef cattle market are less likely, and in these cases we anticipate that should a higher fat product be required, the fat content of the DGS could be augmented through the addition of distillers sorghum oil, 
thereby reducing the volumes of biofuel produced from distillers sorghum oil but not causing additional indirect GHG emissions. Therefore, we do not expect that sorghum oil extraction will have a significant impact on the feed value of DGS and thus will have no significant indirect GHG impacts per pound of DGS. We welcome comment on this assessment. 2. Feedstock Production 
Distillers sorghum oil is removed 
from DGS at dry mill ethanol plants 
using the same equipment and technologies used for corn oil extraction. Oil extraction requires thermal energy to heat the DGS and electricity to power centrifuges, pumps and other oil recovery equipment. Our analysis for the March 2010 RFS final rule,
20the NSP petition, and two 
studies,21 22indicate that although 
extracting oil from DGS uses thermal

23The purpose of lifecycle assessment under the 
RFS program is not to precisely estimate lifecycle 
GHG emissions associated with particular biofuels, but instead to determine whether or not the fuels satisfy specified lifecycle GHG emissions thresholds to qualify as one or more of the four types of renewable fuel specified in the statute. Where there are a range of possible outcomes and the fuel satisfies the GHG reduction requirements when ‘‘conservative’’ assumptions are used, then a more precise quantification of the matter is not required for purposes of a pathway determination.

Summary, Method 1 Fuel Pathway. 
25NSP petition, section F.2.iv 26For example, the California Air Resources 
Board (CARB) estimated this impact would be 
approximately 10 kgCO 2e/mmBtu of biodiesel 
produced from distillers corn oil (https://www.arb.ca.gov/fuels/lcfs/2a2b/apps/co_ bd_wdgs- 
rpt-102414.pdf). Applying such an impact to our analysis of biofuels produced from distillers sorghum oil would not change the GHG thresholds results for the biofuels produced from distillers sorghum oil evaluated in this document. 27See Table 15 in the January 5, 2012 Pathways 
I direct final rule (77 FR 722). 
28See for example: https://www.arb.ca.gov/fuels/ 
lcfs/2a2b/apps/co_ bd_wdgs-rpt-102414.pdf. 
29For details see section 2.4 of the RIA for the 
March 2010 RFS final rule.

facility specific petitions, see: https://www.epa.gov/ renewable-fuelstandard-program/approved- pathways-renewable-fuel. 
31See the March 2013 Pathways I rule, 
specifically 78 FR 14198–14200 (March 5, 2013). energy, it also leads to relatively less 
thermal energy being used later in the process to dry the DGS, resulting in an overall negligible change in thermal energy requirements for plants that dry their DGS. Our analysis here includes both the thermal and electrical energy requirements to remove the distillers sorghum oil. We do not account for the reduction in thermal energy needed for DGS drying mentioned above, so this can be viewed as a conservative approach (i.e., resulting in higher 
estimated GHG emissions) for plants that dry their DGS.
23Based on data 
reviewed by EPA,24we assume 200 Btu 
(British thermal units) of grid electricity and 800 Btu of natural gas are used to extract distillers sorghum oil from DGS, per pound of distillers sorghum oil extracted. These parameters are based on energy requirements associated with extracting oil from DGS at dry mill ethanol plants, but we believe they are also appropriate and conservative in cases where the oil is extracted at any point downstream from sorghum grinding. 
As discussed above, we do not expect 
sorghum oil extraction to significantly change the feed value of DGS on a per pound basis. According to the NSP petition, grain sorghum oil yields should be 0.67 pounds per bushel of grain sorghum feedstock.
25EPA’s 
modeling for the December 2012 grain sorghum ethanol final rule (77 FR 74592) assumed average dried DGS yield of 17 pounds per bushel of grain sorghum feedstock. Thus, sorghum oil extraction may reduce the total mass of DGS produced by up to approximately 4 percent. If full-oil and reduced-oil DGS have equivalent feed value on a per pound basis, we would expect a reduction in the total mass of DGS produced to impact livestock feed markets and result in a net increase in GHG emissions if production of other feed crops (e.g., corn, soybeans) 
increased to backfill the lost DGS, given that producing additional corn and 
soybeans would result in more GHG emissions.
26However, if reduced-oil 
DGS are more beneficial than full oil DGS for dairy cows, on a per pound of DGS basis, that could offset some or all of the impacts associated with the DGS mass reduction. The information currently available makes the magnitude of these countervailing impacts difficult to determine, and we did not include any emissions impacts from DGS mass reduction in our lifecycle GHG analysis of biofuels produced from distillers sorghum oil. We invite comment on our analysis of the GHG emissions associated with extracting sorghum oil from DGS. 
3. Feedstock Transport 
In our analysis, distillers sorghum oil 
is transported 50 miles by heavy duty 
truck from the dry mill ethanol plant to the biodiesel or hydrotreating facility where it is converted to transportation fuel. GHG emissions associated with feedstock transport are relatively small, and modest changes in transport distance are unlikely to affect the results of our analysis. 
4. Feedstock Pretreatment 
For emissions from feedstock 
pretreatment and fuel production, we 
perform two analyses. In the first analysis, we calculate the emissions from biodiesel produced using transesterification. In the second analysis, we calculate the emissions from renewable diesel, jet fuel, LPG, and naphtha, produced using hydrotreating. In Section V below, we then explain how similar results can be inferred for heating oil. 
Before distillers sorghum oil is 
converted to biodiesel via transesterification, it is processed to remove free-fatty acids. This process requires thermal energy. Our evaluation of yellow grease for the March 2010 RFS final rule included 14,532 Btu of natural gas per gallon of biodiesel produced for pretreatment, and we have applied the same assumption for this analysis. According to the NSP petition, distillers sorghum oil has free fatty acid content near or below 15 percent, which is in the range of yellow grease free fatty acid contents (<15 percent).
27This rate of 
thermal energy use for pretreatment is higher than thermal energy rates used in other lifecycle assessments EPA reviewed,
28and can be viewed as a 
conservative assumption (i.e., resulting 
in higher GHG emissions). 
Pretreatment to remove free-fatty 
acids is not required when distillers sorghum oil is used to produce renewable diesel, jet fuel, LPG and naphtha through a hydrotreating process. 
5. Fuel Production 
For biodiesel production, we used the 
transesterification analysis for the 
March 2010 RFS rule for yellow grease biodiesel.
29Based on comparison of this 
yellow grease analysis and the mass and energy balance data in the NSP petition, submitted under claim of CBI, the conversion of yellow grease and distillers sorghum oil are expected to require similar energy inputs and yield similar amounts of biodiesel and methanol as outputs. 
For production of renewable diesel, 
jet fuel, naphtha and LPG via a hydrotreating process, we used the same data and approach as used in the March 2013 Pathways I rule (78 FR 14190, March 5, 2013), and subsequent facility- specific petitions involving hydrotreating processes.
30The March 
2013 Pathways I rule evaluated two hydrotreating configurations: One optimized for renewable diesel production and one optimized for jet fuel production. For this analysis we evaluated a hydrotreating process maximized for renewable diesel production, as that is the most common configuration. The jet fuel configuration results in higher emissions (approximately 5 kgCO
2e/mmBtu 
higher), but the threshold GHG reduction results discussed below are not sensitive to this assumption. 
Our previous analyses of 
hydrotreating processes have applied an energy allocation approach for RIN- generating co-products that qualify as renewable fuel.
31This approach results 
in higher lifecycle GHG emissions for each of the fuel products than other approaches considered, such as a

32See, ‘‘Summary of Key Assumptions for EPA’s 
Analysis of the Lifecycle Greenhouse Gas Emissions 
Associated with Biofuels Produced from Distillers Sorghum Oil,’’ Air Docket EPA–HQ–OAR–2017– 0655. 33See the March 2013 RFS Pathway I rule (78 FR 
14190, March 5, 2013). 
34For example, in analysis for the March 2010 
RFS rule, EPA found that soybean oil biodiesel 
achieves a 57 percent GHG reduction (based on the mean result from our uncertainty assessment), 
whereas the results in Table IV.3, above, show biodiesel produced from distillers sorghum oil achieve a greater than 80 percent reduction. displacement approach, and thus can be 
viewed as a conservative approach. 
In the allocation approach, all the 
emissions from the hydrotreating process are allocated across all co- products. There are a number of ways to do the allocation, for example on the basis of energy, mass, or economic value. Consistent with the approach taken in the hydrotreating analysis for the March 2013 RFS rule, for this analysis of fuels produced from distillers sorghum oil feedstock through a hydrotreating process we allocated emissions to the renewable diesel, naphtha and LPG based on the energy 
content (using lower-heating values) of the products produced. Emissions from the process were allocated equally to all of the Btus of fuel produced. Therefore, on a per Btu basis, all of the primary products coming from the hydrotreating facility have the same emissions from the fuel production stage of the lifecycle. For this analysis, the energy content was the most appropriate basis for allocating emissions because all of the fuel products are used as sources of 
energy. Energy content also has the advantage of being a fixed factor as opposed to market prices which fluctuate over time. 
6. Fuel Distribution 
We used the fuel distribution results 
from the biodiesel analysis for the 
March 2010 RFS rule. Fuel distribution emissions are relatively small compared to baseline lifecycle GHG emissions (see Table IV.3 below), and although they may be different for different types of fuel, for the purposes of this analysis we assume that renewable diesel, jet fuel, LPG, and naphtha, have the same fuel distribution emissions per mmBtu of 
fuel used. Even if we applied a more precise value for fuel distribution emissions, we do not expect that revision to change our assessment that these fuels meet a 50 percent GHG emission reduction. 
7. Fuel Use 
For this analysis we applied fuel use 
emissions factors developed for the March 2010 RFS final rule. For biodiesel 
we used the biodiesel emissions factor. For renewable diesel and jet fuel we used the emissions factors for non-CO
2 
GHGs for baseline diesel fuel. For naphtha we used the emissions factors for non-CO
2GHGs for baseline gasoline 
fuel. For LPG we used the LPG non-CO 2 
emissions factor developed for the March 2010 RFS rule. The tailpipe emissions are relatively small, and the threshold GHG reduction results are not sensitive to these assumptions. More details on our analysis of fuel use emissions are described in a memo
32to 
the rulemaking docket. 
8. Results of GHG Lifecycle Analysis 
Table IV.3 shows the lifecycle GHG 
emissions associated with biofuels 
produced from distillers sorghum oil that result from our assessment. The table also shows the percent reduction relative to the petroleum baseline. All of the fuels are compared to the diesel baseline, except for naphtha which is compared to the gasoline baseline.

V. Consideration of Lifecycle Analysis Results 
Based on the lifecycle GHG emissions 
results presented above, all of the pathways evaluated would meet the 50 percent GHG reduction threshold required for advanced biofuel and biomass-based diesel. 
The results presented above would 
also justify qualifying heating oil produced from distillers sorghum oil as meeting the 50 percent GHG threshold. In previous rulemakings, EPA considered the lifecycle GHG impacts associated with heating oil and determined that heating oil produced from a range of feedstocks (e.g., soybean 
oil, distillers corn oil) via a 
transesterification or hydrotreating process satisfies the 50 percent lifecycle 
GHG reduction required for advanced biofuel.
33Based on the results presented 
above, we anticipate that biofuels such as heating oil produced from distillers sorghum oil have significantly lower lifecycle GHG emissions than the same fuels produced from soybean oil, when the same production processes are used.
34Therefore, based on EPA’s 
previous lifecycle evaluations for heating oil produced from soybean oil, we believe that heating oil produced from distillers sorghum oil would also 
satisfy the 50 percent GHG reduction requirement. 
VI. Summary 
Based on our GHG lifecycle 
evaluation described above, we propose 
to find that biodiesel and heating oil produced from distillers sorghum oil via a transesterification process, and renewable diesel, jet fuel and heating oil produced from distillers sorghum oil via a hydrotreating process meet the 50 percent GHG reduction threshold requirement for advanced biofuel and biomass-based diesel. This finding

would support a determination that 
these fuels are eligible for biomass- based diesel (D-code 4) RINs if they are produced through a process that does not co-process renewable biomass and petroleum, and for advanced biofuel (D-code 5) RINs if they are produced through a process that does co-process renewable biomass and petroleum. EPA invites comment on all aspects of its analysis of these proposed biofuel pathways. 
VII. Statutory and Executive Order 
Reviews 
Additional information about these 
statutes and Executive Orders can be found at http://www2.epa.gov/laws- regulations/laws-and-executive-orders. 
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 and was therefore not submitted to the Office of Management and Budget (OMB) for review. 
B. Executive Order 13771: Reducing 
Regulations and Controlling Regulatory Costs 
This action is not expected to be an 
Executive Order 13771 regulatory action 
because this action is not significant under Executive Order 12866. 
C. Paperwork Reduction Act (PRA) 
This action does not impose any new 
information collection burden under the 
provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and 
therefore is not subject to these requirements. 
D. Regulatory Flexibility Act (RFA) 
I certify that this action will not have 
a significant economic impact on a 
substantial number of small entities under the RFA. This action will not impose any requirements on small entities. An agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, has no net burden or otherwise has a positive economic effect on the small entities subject to the rule. This rule proposes to provide a positive economic effect for distillers sorghum oil producers and producers of biofuels from distillers sorghum oil as they would be able to participate in the RFS program, see CAA section 211(o). E. Unfunded Mandates Reform Act 
(UMRA) 
This action does not contain an 
unfunded mandate of $100 million or more as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. The action imposes no enforceable duty on any state, local or tribal governments or the private sector. 
F. 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. 
G. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This action does not have tribal 
implications as specified in Executive Order 13175. This proposed rule would affect only producers of distillers sorghum oil and producers of biofuels made from distillers sorghum oil. Thus, Executive Order 13175 does not apply to this action. 
H. Executive Order 13045: Protection of 
Children From Environmental Health Risks and Safety Risks 
The EPA interprets Executive Order 
13045 as applying only to those regulatory actions that concern environmental health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of ‘‘covered regulatory action’’ in section 2–202 of the Executive Order. This action is not subject to Executive Order 13045 because it because it does not concern an environmental health risk or safety risk. 
I. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This action is not subject to Executive 
Order 13211 because it is not a significant regulatory action under Executive Order 12866. 
J. National Technology Transfer 
Advancement Act (NTTAA) 
This rulemaking does not involve 
technical standards. K. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
The EPA believes that this action does 
not have disproportionately high and adverse human health or environmental effects on minority populations, low- income populations and/or indigenous peoples, as specified in Executive Order 12898 (59 FR 7629, February 16, 1994). This proposed rule does not affect the level of protection provided to human health or the environment by applicable air quality standards. This action does not relax the control measures on sources regulated by the fuel programs and RFS regulations and therefore will not cause emissions increases from these sources.

AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : The Environmental Protection 
Agency (EPA or Agency) proposes to establish federal nutrient criteria to protect designated uses for the State of Missouri’s lakes and reservoirs. On August 16, 2011, EPA disapproved most of the numeric criteria for total nitrogen, total phosphorus, and chlorophyll a that 
the State submitted to EPA in 2009. EPA acknowledged the importance of Missouri’s proactive efforts to address nutrient pollution by adopting numeric nutrient criteria. However, EPA concluded that the Missouri Department of Natural Resources (MDNR) had failed to demonstrate the criteria would protect the State’s designated uses and were not based on a sound scientific rationale. The Clean Water Act (CWA) directs EPA to promptly propose water quality standards (WQS) that meet CWA 
requirements if a state does not adopt WQS addressing EPA’s disapproval. On February 24, 2016, the Missouri Coalition for the Environment (MCE) filed a lawsuit alleging that EPA failed to satisfy its statutory obligation to act ‘‘promptly.’’ On December 1, 2016, EPA entered into a consent decree with MCE committing to sign a notice of proposed rulemaking by December 15, 2017 to 
address EPA’s 2011 disapproval, unless the State submits and EPA approves criteria that address the disapproval on or before December 15, 2017. As of the date of this proposed rule, Missouri has not submitted new or revised standards to address EPA’s 2011 disapproval and EPA has not approved such water quality standards. Therefore, under the terms of the consent decree, EPA is signing a notice of proposed rulemaking that proposes new water quality standards addressing EPA’s August 16, 2011 disapproval. In this proposal, EPA seeks comment on two primary alternatives. Under the first alternative, EPA proposes nutrient protection values and eutrophication impact factors in a combined criterion approach. Under the second alternative, EPA proposes a similar combined criterion approach that would mirror the State of Missouri’s October 2017 proposal for lake nutrient water quality standards. EPA will not proceed with final rulemaking (or will withdraw its final rule, if applicable) to address its 2011 disapproval if Missouri adopts and submits criteria to address EPA’s 2011 
disapproval and EPA approves them as meeting CWA requirements.
