First,** EPA is proposing to amend certain of the renewable fuels standard (RFS2) program regulations at 40 CFR Part 80, Subpart M . We believe these proposals will facilitate the introduction of new renewable fuels as well as improve implementation of the program . T his proposal includes various changes related to biogas, including changes related to the revised compressed natural gas (CNG)/liquefied natural gas (LNG) pathway

and amendments to various associated registration, recordkeeping, and reporting provisions. This proposed regulation includes the addition of new pathways for renewable diesel , renewable naphth a, and renewable electricity (used in electric vehicle s ) produced from landfill biogas. Adding these new pathway s will enhance the ability of the biofuels industry

to supply advanced biofuels, includin g cellulosic biofuels, which greatly reduce the greenhouse gas emissions (GHG) compared to the petroleum - based fuels they replace. Italso addresses “nameplate capacity” issues for certain production facilities that do not claim exemption from the 20% gre enhouse gas (GHG) reduction threshold. In this notice, EPA addresses issues related*** E.O. 12866 Review

2 to crop residue and corn kernel fiber and proposes an approach to determining the volume of cellulosic RI

Ns produced from various cellulosic feedstocks. We also include a lifecycle anal ys is of advanced butanol and discuss the potential to allow for commingling of compliant products at the retail facility level as long as the environmental performance of the fuels would not be detrimental. Several other amendments to the RF S2 program are included . Second, EPA is also proposing various changes to the E15 misfueling mitigation regulations (E15 MMR) at 40 CFR Part 80, Subpart N. Among the E15 changes proposed are technical corrections and amendments to sections dealing with labeling, E15 survey s, product transfer documents, and prohibited acts. We also propose to amend the definitions in order to address a concern about the rounding of test results for ethanol content violations. Lastl y, EPA is proposing changes to the survey requirements associat ed with the ultra low sulfur diesel (ULSD) program.

7 **I. Why is EPA Taking This Action?** EPA is t aking this action to amend various provisions in its regulations pertaining to fuels and fuel additives. First, EPA is proposing to amend 40 CFR Part 80, Subpart M related to the renewable fuels standard (RFS). The RFS2 program was required b y the Energ y Independence and Securit y Act of 2007 (EI SA 2007), which amended the Clean Air Act (CAA). The final regulations for RFS2 were published in the Federal Register on March 26, 2010 (75 FR 14670). In this notice, references to the “RFS2 final rule” refer to the March 26, 2010 Federal Register notice unless otherwise noted. Second, EPA is proposing to amend provisions of 40 CFR Part 80, Subpart N, related to misfueling mitigation for 15 volume percent (%) ethanol blends (E15) . The final regulations for E15 were published in the Federal Register on July 25, 2011 (76 FR 44422). Several items in this proposed action will assist regulated parties in complying with RFS2 and E15 requirements. This action is not expected to result in significant changes in regulatory

burdens or costs associated with the RFS2 and E15 programs. Third , EPA is proposing a change to the ultra low sulfur diesel (UL SD) program of 40 CFR Part 80, Subpart I. Specificall y, EPA is proposing an amendment to th e survey provisions that would likely result in decreasing the number of samples that must be taken, and as such would be expected to result in a decrease in regulatory

burdens or costs. **II. Does This Action Apply to Me?** Entities potentially

affected by

this action include those involved with the production, distribution and sale of transportation fuels, including gasoline and diesel fuel, or renewable*** E.O. 12866 Review

10 C. Docket Copying Costs . You may be charged a reasonable fee for photocopying docket materials, as provided in 40 CFR Part 2. **IV. Executive Summary**  EPA is proposing amendments to three sets of regulations. First, EPA is proposing to amend certain of the renewable fuels standard (RFS2) program regulations at 40 CFR Part 80, Subpart M. Section V of this preamble includes several proposed amendments to the renewable fuel standard (RFS2) regulations of 40 CFR Part 80. The final regulations for RFS2 were published in the Federal Register on March 25, 2010 (75 FR 14670). EPA has issued technical corrections in the past. We have identified several additional changes . Some of the proposed changes in this notice are of a substantive nature; others are more in the nature of technical corrections, including corrections of obvious omissions and errors in citation. Among the more substantive modifications are various proposed changes related to biogas, including changes rel ated to the revised compressed natural gas (CNG)/liquefied natural gas (LNG) pathway and amendments to various associated registration, recordkeeping, and reporting provisions. These fuels have the potential to add notable volumes of advanced biofuel including cellulosic biofuel to the existing renewable fuel volumes already being produced. Man y of these changes are being proposed in order to facilitate the introduction of new renewable fuels under the RFS2 program and have come at the suggestion of industry stakeholders . This preamble includes the addition of new pathway s for renewable diesel , and renewable naphtha , and renewable electricity (used in electric vehicles) produced from landfill*** E.O. 12866 Review

11 biogas. It includes a proposal to address “nameplate capacit y” issues for certain production facilities that do not claim exemption from the 20% greenhouse gas (GHG) reduction threshold. EPA proposes to address issues related to crop residue and corn kernel fiber. We propose an approach for approving the cellulosic volumes from cellulosic feedstocks. We include a lifecycle anal ys is of advanced butanol and discuss the potential to allow for c ommingling of compliant products at the retail facility level as long as the environmental performance of the fuels would not be detrimental when compared to existing practices. We specificall y discuss this consideration for commingling in regards to the volatility associated with butanol gasoline and ethanol gasoline blends. We state when and how EPA may cancel a company registration . Of a more minor scope, this preamble includes proposed amendments that would define terminology used for registration an d reporting purposes and propose changes to registration and reporting requirements . This preamble also discusses some minor corrections, including adding language to registration, recordkeeping and reporting sections requiring English language translation of documents. We have also proposed to correct obvious omissions and errors in citation in the existing RFS2 regulation. Second, EPA is also proposing various changes to the E15 misfueling mitigation regulations (E15 MMR) at 40 CFR Part 80, Subpart N. The final E15 MRR was published in the Federal Register on July 25, 2011 (76 FR 44406). Among the E15 changes proposed are technical corrections and amendments to sections dealing with labeling, E15 survey s, product transfer documents, and proh ibited acts. We also propose to amend the definitions in order to*** E.O. 12866 Review

12 address a concern about the rounding of Reid Vapor Pressure (RVP) test results, in response to a question raised b y some industry stakeholders. Third, i n response to questions received from regulated parties, we propose to amend the ultra low sulfur diesel (ULSD) survey provisions in a manner that will likely reduce the number of samples required. This may mean a reduction in costs and burdens associated with compliance for regulated p arties, with no expected degradation in the highly successful environmental performance of the program . **V. Renewable Fuel Standard (RFS2) Program Amendments**  The RFS2 program was required b y the Energy Independence and Securit y Act of 2007 (EI SA 2007), which amended the Clean Air Act (CAA). The final regulations for RFS2 were published in the Federal Register on March 26, 2010 (75 FR 14670). The rule took eff ect on July 1, 2010. In this notice, we are proposing several new renewable fuel pathway options for advanced biofuels including new cellulosic biofuel pathway s. This proposed regulation would also provide modifications and technical amendments to the existing RFS2 program . A. Approving Cellulosic Volumes from Cellulosic Feedstock Since the inception of the RFS program, EPA has qualified several fuel pathway s that are able to generate cellulosic biofuel RINs (D codes 3 and 7). See 40 CFR 80.1426. Each of the qualified cellulosic feedstocks listed in section 80.1426 contain other components such as*** E.O. 12866 Review

13 starches, sugars, lipids, and proteins . To date, EPA has not provided detailed information on how other components shou ld be treated. This has led to uncertaint y amongst renewable fuel producers about whether their entire volume of fuel produced from a cellulosic feedstock would be eligible to generate cellulosic RINs. In this rulemaking, EPA proposes to allow 100% of th e volume of renewable fuel produced from certain specified, currentl y approved cellulosic feedstocks to generate cellulosic (D - 3 or D - 7) RINs. We also take comment on two alternative approaches for how to treat non - cellulosic components of cellulosic feedstocks. For purposes of the RFS program, cellulosic biofuel is defined as “renewable fuel derived from an y cellulose, hemicellulose, or lignin that is derived from renewable biomass and that has lifecycle greenhouse gas emissions, as determined by the Administrato r, that are at least 60 percent less than the baseline lifecycle greenhouse gas emissions.” This definition was added in Section 211(o)(1)(E) by the Energy Independence and Securit y Act (E IS A) of 2007, where Congress specified four different categories of renewable fuel and their associated volume requirements. The threshold for reduction in greenhouse gases is set at a higher percentage for cellulosic biofuel than the reduction for the other categories of renewable fuels. While the volume requirement s for cellulosic biofuel start at a relativel y low volume, Congress specified large volume increases over time such that the main growth in the use of renewable fuels comes from cellulosic biofuels. This reflects a strong Congressional intention to promote the use of cellulosic biofuel and achieve the associated greenhouse gas emissions reductions. However , no plant matter can ever consist entirel y of cellulose, hemicellulose and lignin. Plants require proteins, DNA, carboh ydrates and many other types of compounds in order to*** E.O. 12866 Review

14 grow and function. Even feedstocks such as switchgrass, corn stover, and woody materials which are the most commonly cited “cellulosic” feedstocks, contain measurable proportions of other ty pes of organic molecules. How ever, these “cellulosic” feedstocks contain much more cellulose, hemicellulose and lignin than do other ty pes of biomas s . As shown in Table V.A. - 1 , most “ cellulosic ” feedstocks consist of approximately 80 - 95% cellulose, hemicellulose, or lignin . 1 In contrast, corn kernels contain roughl y 75% starch and less than 10 % fiber (which includes the cellulosic components, as well as other materials), 2 and soy beans are roughl y 60% oil and protein and only

about 15 % fiber 3 . **Table V.**  **A .**  **- 1.**  **Average c ellulosic composition of different types of feedstocks.**  **4** Feedstock Type Average Adjusted Cellulosic Composition Crop Residue 90 % Switchgrass 85% Miscanthus 85% Other Grasses 8 1 % Wood and Branches 92% EPA is proposing to allow 100% of the volume of renewable fuel produced from specific ce llulosic feedstock sources found in Table 1 of section 80.1426 to generate D - 3 or D - 7 RINs (depending on the t ype of finished fuel). However s eparated food waste, separated yard waste, and separated MSW would continue to be treated as before, as dis cussed below .

15 major justifications for this determination: 1) there can be significant variation in the amount of cellulosic content in an y feedstock, which varies within a growing season, across samples, and across sites. Attempting to a ccount for this variability would impose a significant administrative burden on producers and EPA ; 2) The amount of the final fuel that is produced from the cellulosic portion of the feedstock is likely to be very

high, particularly

for fuels produced using a biochemical reaction ; 3) EPA has alread y made previous determinations in which a single RIN value was assigned to the fuel produced since it came primarily from one source even though it was also produced from incidental amounts of other sources. This determination is based on the view that the statutory requirement does not mandate that in all cases the renewable fuel must be prod uced solel y from the cellulosic material in the renewable biomass. EPA considers the statutory definition of cellulosic biofuel to be flexible on this point. Given these factors cited above, the Agency believes this interpretation of “derived from” is co nsistent with the Congressional intent to require increased use of cellulosic biofuels while ensuring that the program can be implemented in a reasonable way . Details on the variability

in feedstocks, characteristics of the final fuel, previous precedents, and alternative proposals are included in the following sections. 1. Variability

in Cellulosic Content Estimates of Feedstocks The cellulosic components of feedstock consist of the major structural components; cellulose; hemicellulose; and lignin. EPA has reviewed research characterizing the different components of feedstocks, mainly focused on how the materials could be broken down and*** E.O. 12866 Review

16 converted into fuel. There has been work also in defining standa rdized procedures and test methods for anal yz ing the different components of biomass 5 ; however, the studies considered all employ slightl y different methods. For the purposes of this rule, EPA considered the amount of the feedstocks that is composed of cel lulosic components i.e., how much comes from the cellulose, hemicellulose or lignin, as opposed to any other components of the feedstock. There is significant variation in the data reported on feedstock component compositions. The variation is due to a number of causes, such as measurement methods 6 , 7 , variety within a generic feedstock ty pe, and storage time 8 . Although there are man y factors that contribute to the large variability in assessments of cellulosic content, all studies confirm that the feedst ocks in Table 1 of section 80.1426 have an adjusted cellulosic content of at least 70% , with an average content of around 85% cellulosic . 9 A memorandum to the docket provides more information on cellulosic terminology , percent

considered the organic components of the materials when determining cellulosic content. Inorganic materials are not likel y to end up in the final fuel product and would not contribute to the fuel heating c ontent in the event that they remained in the final fuel. This methodology

is consistent with how RI Ns are determined. In this section, EPA refers to this as “adjusted cellulosic”. Adjusted cellulosic content does not consider other material that is not c onverted into biofuel such as minerals or other components that would show up as part of the ash remaining after a thermo - chemical conversion process.*** E.O. 12866 Review

17 composition of various feedstocks, and the variability of different feedstock components. 10 From this data, EPA concludes that each of the qualified feedstocks listed in section 80.1426 are comprised predominantly of cellulose, hemicellulose and lignin. 2. Characteristics of the Amount of the Final Fuel Produced from Cellulosic Materials Process technology

play s a key

role in how much of the final fuel product is actually produced from cellulose, hemicellulose, or lignin. There are two basic processes for converting cellulosic feedstocks into fuel: thermo - chemical and biochemical. Thermo - chemical processes mainly consist of p yrol ys is

– in which cellulosic biomass is decomposed with temperature to bio oils and could be further processed to produce a finish ed fuel

– and gasification

– in which cellulosic biomass is decomposed to sy nthesis gas (“s yn gas”) with further cataly tic processing to produce a finished fuel product. The biochemical process requires the release of sugars from biomass and the use of mic roorganisms to convert sugars into fuels. Thermo - chemical processes can accept a more heterogeneous mix of feedstock and ty pically convert all of the organic components of the feedstock into finished fuel. The biochemical process generall y accepts a more homogeneous mix of feedstocks and t ypically converts only the cellulosic and hemicellulosic components of the feedstock into the final fuel product. Therefore, regardless of the feedstock used, the final fuel produced from the biochemical process will ty picall y only come from the cellulosic or hemicellulosic portions of feedstock, while the final fuel produced from the thermo - chemical process could come from cellulosic and non - cellulosic components.

18 For thermo - chemical production in which the non - cellu losic components of the feedstock can contribute to the volume of fuel produced in addition to the cellulosic components, the percent of fuel produced from the non - cellulosic portion can vary due to such factors as feedstock t ype and the time and location of feedstock harvest. Regardless, we believe that the majority of the fuel produced will be from the cellulosic components. As a practical matter, there is no simple test that can be used to measure the amount of fuel end product that originated from cel lulosic materials. F or fuel produced via the biochemical process, 100% of the fuel produced is directly

the result of conversion of the cellulosic content. In selecting a cellulosic process, whether based on biochemical or thermo - chemical design, the fuel producer is clearl y demonstrating that its primary intent is to convert the cellulosic portions of the feedstock. Cellulosic fuel producers invest in expensive process technologies with the intent of converting the cellulosic components of a feedstock into fuel; conversion of the non - cellulosic components can be achieved much more easily with less of a capital investment. Furthermore, since the fuel produced will be primaril y the result of the direct conversion of cellulosic content of the feedstock and considering the relatively small range of non - cellulosic portion of feedstock that could contribute to the volume of fuel produced, EPA believes it is reasonable to consider all the fuel produced when rel yi ng on cellulosic conversion processes to be cellulosic biofuel. 3.

considered instances where one RI N value was assigned to the fuel produced since it came primarily from one source even though it was also produced from some amount of other chemical compounds . Inthe March 2010 RFS rulemaking, EPA discussed two different situations for fuel produced from separated y ard waste and food waste as the renewable biomass feedstock. The first involved food waste or y ard waste that was kept separate, from generation, from municipal solid waste (MSW). EPA determined that both of the se feedstocks could be considered renewable biomass. With respect to separated yard waste, EPA determined that the yard waste was expected to be composed almost entirely of woody material or leaves, and this would be deemed to be cellulosic material and wo uld generate cellulosic biofuel RI Ns. Separated food waste, however, was likel y to be composed of both cellulosic and non - cellulosic materials, and in certain cases would likel y be composed primarily of non - cellulosic materials, such as sugars and starche s from the food. EPA determined that separated food waste would be deemed to be non - cellulosic material, and would generate advanced biofuel RI Ns and not cellulosic RI

Ns, unless the renewable fuel producer demonstrated the part of the food waste that was cellulosic. This portion would then generate cellulosic RI Ns. 75 FR 14670, 14706 (March 26, 2010). The second situation EPA previously addressed involved separated MSW. EPA determined that separated MSW that met certain regulatory requireme nts would qualify as a renewable biomass for purposes of producing renewable fuel. EPA recognized that the biogenic portion of this feedstock would be composed of a “variet y of materials, including yard waste (largel y cellulosic) and food waste (largel y s tarches and sugar), as well as incidental materials remaining after reasonably practicable separation efforts such as plastic and rubber of fossil*** E.O. 12866 Review

20 origin.” Testing could identify the portion of the fuel produced from biogenic materials, and these biogenic materials “will likely be largel y derived from cellulosic materials (yard waste, textiles, paper, and construction materials), and to a much smaller extent starch - based materials (food wastes).” However, EPA was not aware of a test method to distinguish between renewable fuel produced from the cellulose and fuel produced from the starch and under those circumstances determined that it was appropriate to base the assignment of RI Ns on the “predominant” component of the biogenic material. EPA thus determin ed that all of the fuel generated from the biogenic portion of separated MSW would be considered cellulosic biofuel. 75 FR at 14706. Thus, EPA has interpreted the definition of cellulosic biofuel as including in some cases a renewable fuel that is produ ced from both the cellulosic and incremental amounts of non cellulosic components of the feedstock. EPA has treated the resulting fuel as all derived from cellulosic material where the feedstock is composed almost entirel y of woody materials and leaves, o r where the predominant component of the feedstock is likely cellulosic. The fuel will be largel y derived from this cellulosic material and to a much smaller extent from non - cellulosic materials. There currently is no ready

test to identify

the portion o f fuel produced from non cellulosic materials. EPA has not considered the fuel as cellulosic in cases where the feedstock was likely

to be largel y non - cellulosic materials . In all of these cases, EPA has recognized that the fuel would be produced from both the cellulosic and non - cellulosic materials in the feedstock, and has determined in some cases to consider the fuel entirel y cellulosic biofuel based on the relative amo unts of the cellulosic and non - cellulosic materials and, for fuel made from the*** E.O. 12866 Review

21 biogenic portion of separated MSW, on the lack of availability of a test procedure to differentiate how much of the fuel came from the cellulosic materials. These determinat ions have been based on the view that the statutory requirement that cellulosic biofuel be “derived from cellulose, hemicellulose, or lignin” does not mandate that in all cases the renewable fuel must be produced solely from the cellulosic material in the renewable biomass. EPA considers the statutory definition of cellulosic biofuel to be ambiguous on this point, providing EPA the discretion to reasonably determine under what circumstances a fuel appropriatel y could be considered cellulosic biofuel whe n the fuel is produced from a feedstock that is a mixture of cellulosic and non - cellulosic materials. To date , EPA has specified certain circumstances where the entire fuel will be considered cellulosic biofuel. EPA has taken this action in cases where the cellulosic material is almost entirely wood y m aterials or leaves, or the fuel is produced from materials that are predominantly composed of cellulosic materials and to a much smaller extent non - cellulosic materials, with no current test to identify the differing portions. There have been two elements present in these decisions. One involves a determination that the feedstock is composed almost entirely or largel y of cellulosic materials. EPA has also considered whether or not there is a test method to identify the actual portion of the fuel produced from cellulosic materials. In this rulemaking EPA is proposing an approach that is consistent with and an outgrowth of the approach taken in the RFS2 rulemaking. EPA is proposing to approve certain fuels as cellulosic biofuel where the cellulosic components account for a predominant percentage of the biogenic material in the renewable biomass feedstock used*** E.O. 12866 Review

22 to produce the fuel, even where the non - cellulosic components of the renewable biomass could b e reasonabl y identified or estimated . 11 EPA is proposing to classify all of the biofuel as cellul osic in the fuel pathway s proposed today , where the cellulosic material makes up a predominant percentage of the organic material from which the fuel is produced. This approach will avoid the administrative and technical burden on producers and EPA of trying to determine the specific amounts of cellulosic and non cellulosic materials in the specified high - cellulosic feedstock sources, removing potential difficult and potentially

time - consuming and expensive impediment to expansion of the cellulosic biofuel industry . The growth in cellulosic biofuel volumes promoted by today ’s proposal is expected to result in greater reductions in GHGs, as all of the biofuel qualified as cellulosic would have to achieve the minimum 60% reduction in GHG emissions specified in the Act. EPA’s application of this approach to the specific fuel pathway s and feedstocks discussed in this proposal is intended to ensure that cellulosic materials are the predominant portion of the biogenic materials used to produce cellulosic biofuel. This approach avoids administrative , technical and cost burdens on EPA and industry and promotes the volume and greenhouse gas objectives of Congress. EPA proposes that this is a reasonable interpretation of the definition of cellulosic biofuels, and invites comment on this approach. 12

11 By predominant, EPA means the very high percentages for adjusted cellulosic content discussed in section V. A.1. above for the feedstocks at issue in this proposal. 12 See Bot v.

23 EPA is proposing that biofuel made from the following cellulosic feedstocks will be able to generate applicable cellulosic RI Ns for 100% of the volume produced: crop residue ; slash; pre - commercial thinnings an d tree residue; annual cover crops; switchgrass; miscanthus ; and energy cane . EPA’s prior treatment of separated yard waste, separated food waste, and separated MSW is discussed above and is not being changed. On January 5, 2012, EPA proposed to qualify napier grass and Arundo donax as new feedstocks that would be eligible to generate cellulosic RI

Ns. If those pathway s are approved before this rule is final, EPA is proposing to apply the approach discussed above to the se feedstocks as well. 13 To the extent that additional cellulosic pathway s are approved in the future, we would expect to apply this same methodology to those feedstocks as well , but will evaluate them on a case - by - case basis . EPA requests comments on this proposed approach to allow 100% of the volume of renewable fuel produced from the specified cellulosic feedstock sources found in Table 1 of section 80.1426 to generate cellulosic RINs. We also take comment on the cellulosic content values presented for different feedstocks. In addition , we request comments about an y anal yt ical methods that may

exist to determine what percent of a finished biofuel product may have derived from cellulos ic versus non - cellulosic components. We also request comment on the alternative approaches outlined below. 4. Alternative Approaches

24 EPA seeks comment on two alternative approaches to assigning cellulosic RI Ns to fuels produced from the cellulosic feedstocks discussed above . Separate from the specific pathway s addressed in this proposal, EPA also seek s comment on potential approaches for assigning cellulosic RI

Ns for anticipated future pathway s for renewable fuels produced from feedstoc ks that contain lower cellulosic content than those discussed in this rulemaking. . Cellulosic Content Threshold Approach An alternative approach for handling the variability in cellulosic content would be for EPA to set a minimum threshold of cellulos ic content in the feedstock. Fuels produced from feedstocks with a cellulosic content above this minimum threshold would be eligible to generate cellulosic RI

Ns for 100% of their volume. Thresholds under consideration would range from 70% to 99.9%. A hi gher percentage would place more emphasis on the feedstock content having a higher actual cellulosic component, whereas the lower percentages would place more emphasis on promoting the volume of fuels that could be categorized as cellulosic biofuel. EPA invites comment on this approach, and also invites comment on the most appropriate value to use as the threshold. Furthermore, EPA invites comment on whether individual producers should be responsible for submitting data that their feedstock meets this thre shold, or whether EPA should determine whether feedstocks meet this threshold based on existing published data. Since biochemical processes generally onl y convert the cellulosic , hemicellulosic, or lignin components of the feedstock to fuel, EPA believes under this alternative approach, it may still be appropriate to allow fuel producers using biochemical processes to generate RINs for*** E.O. 12866 Review

25 100% of the fuel produced from cellulosic feedstocks . EPA requests comments on our assumption that bio chemical processes will be specific for the cellulosic components, and we also request comment on whether to allow 100% of the fuel produced via biochemical processes to generate cellulosic RINs. Specified Percentage Approach As noted above, examining the range of feedstock data compiled b y EPA, it appears that 85% would be a reasonable approximation for the average adjusted cellulosic content across a range of assessments of the specific feedstock s that are qualified to produce cellulosic fuel. Under this approach, fuels produced from the cellulosic feedstocks discussed above would be eligible to generate cellulosic RI Ns for 85% of their volume, and the remaining 15% would be eligible to generate a dvanced RINs . The specified percentage approach would reduce administrative burden but also incentivize renewable fuel production. For this approach, EPA would effectivel y be treating 85% of the fuel produced from all of these feedstock sources as bein g derived from cellulosic material. However, EPA would consider allowing a larger percentage of the fuel to qualify for cellulosic RINs if the producer could submit data that demonstrates a consistently higher cellulosic content in their feedstock. Under this approach, producers could submit a written plan for approval under the registration procedures in 40 CFR 80.1416(b)(vii). The plan would need to detail the cellulosic content of the feedstock, the method used for quantifying the cellulosic and non - cel lulosic contents, and the production process used.*** E.O. 12866 Review

26 Since biochemical processes generally onl y convert the cellulose, hemicellulose, or lignin components of the feedstock to fuel, EPA believes under this alternative approach it would be appropriate to al low fuel producers using biochemical processes to generate RI Ns for 100% of the fuel produced from cellulosic feedstocks. EPA requests comments on our assumption that biochemical processes will be specific for the cellulosic components, and we also reques t comment on whether to allow 100% of the fuel produced via biochemical processes to generate cellulosic RI

Ns. Request for Comment on Potential Approaches for Fuels Produced from Feedstocks with Lower Cellulosic Content Finally , EPA anticipates that in the future , we may address biofuels that are produced from feedstock s that contain lower cellulosic content than those discussed in this rulemaking. Accordingl y, we request comment on how EPA should assign RINs to the fuels produced fr om feedstocks with lower cellulosic content than those presented in this rulemaking but for which some of the fuel is produced from the cellulosic components. One possible example would be a feedstock that contained in the range of 40 - 60 % cellulose, hemic ellulose and lignin , where the fuel was produced using thermochemical methods such that the same percentage of the fuel may come from cellulosic materials. EPA invites comments about what approaches could be taken for assigning cellulosic RINs to the biof uel. For example, would one or more of the approaches outlined above be appropriate for assigning RINs to this fuel? Are there variations on these approaches that EPA should consider? EPA also invites comments on how to assign cellulosic RI Ns where proc esses other than thermochemical methods are used.*** E.O. 12866 Review

27 B. Lifecycle Greenhouse Gas Emissions Analy sis for Renewable Electricit y, Renewable Diesel and Naphtha Produced from Landfill Biogas EPA has received several facility - specific petitions under § 80. 1416 to allow renewable electricit y, renewable diesel and naphtha produced from landfill biogas to qualify as renewable fuels under the RFS program. Since these new pathway s could be more broadly applicable, EPA is proposing to add these pathway s to Table 1 to § 80.1426 through this rulemaking process. Based on questions from companies, EPA is also modifying the existing biogas pathway to specify that compressed natural gas (CNG) or liquefied natural gas (LNG) is the fuel and biogas is the feedstock. For this proposal, EPA considered both the cellulosic origin of landfill biogas and the lifecycle GHG impacts of three t yp es of fuel produced from landfill - derived biogas. In the final RFS2 rule, EPA established biogas as a fuel ty pe when derived from landfi lls, sewage waste treatment plants, and manure digesters. This biogas was classified as an advanced biofuel eligible to generate D - Code 5 RINs. EPA also established cellulosic diesel and cellulosic naphtha as cellulosic biofuels eligible to generate D - Co de 7 and 3 RINs, respectively . The eligible feedstocks for these biofuels include cellulosic components of separated municipal solid waste but did not include biogas from landfills. Based in part on additional information received through the peti tion process for EPA approval of renewable electricit y and renewable diesel and naphtha produced from landfill biogas, EPA has evaluated these pathway s and is proposing to include renewable electricity produced from landfill biogas feedstock in Table 1 to § 80.1426 as a cellulosic fuel t ype.

28 that RI Ns may onl y be generated for electricit y from biogas that can be tracked to use in the transportation sector, such as by an electric vehicle. We are also proposing to add renewable diese l produced from landfill biogas via the Fischer - Tropsch process as an approved advanced and/or biomass - based diesel biofuel and naphtha produced from landfill biogas via the Fischer Tropsch process as an approved advanced biofuel . If the Fischer - Tropsch facilities produce at least 20% of their electricity demand at the facility

from certain allowed sources , we are proposing that the renewable diesel and naphtha produced would further qualify as cellulosic biofuels . We are also proposing to amend the existing biogas pathway to list renewable CNG/L NG as the fuel types instead of biogas since the biogas is converted into CNG or L NG before being used as a transportation fuel, as discussed below. Renewable CNG/L NG produced from biogas from waste treatment plants and waste digesters is still classified as an advanced biofuel. However, renewable CNG/LNG produced from biogas from landfills now qualifies as a cellulosic pathway . The changes to the renewable CN G/L NG pathway

are described in section C . 1. “ Changes Applicable to the Revised CNG/LNG pathway from Biogas ” below.
1. Feedstock Production When waste materials are buried in a landfill, decomposition of the organic materials consumes all of the ox yg en present within roughly one year, leaving the bulk of the material to undergo slower, anaerobic decomposition. This process produces large amounts of methane for several decades, as well as other products, with the gases released as “biogas.” Biogas from landfills ty

29 trace amounts of other gases. Methane is a potent greenhouse gas (GHG) , with a global warming potential of 21 times that of carbon dioxide, and landfills are the third - largest anthropogenic source of methane to the atmosphere in the United States. 14 The methane present in biogas is also a potential energy source that may

be purified and compressed to be used directl y in CNG or LNG vehicles, combusted to produce electricit y or converted to renewable diesel and naphtha via the Fischer - Tropsch process. The March 2010 RFS final rule concluded that municipal solid waste ha s no agricultural or land use change GHG emissions associated with its production. Furthermore, the feedstock for these fuels is landfill biogas, which already appears in Table 1 of § 80.1426(f) of the RFS2 regulations and has already been evaluated as part of the RFS2 final rule lifecycle GHG determinations. Therefore no new renewable feedstock production modeling was requir ed, no GHG emissions were attributed to feedstock production for any of these renewable fuel pathway s, and EPA focused our anal ys is on the new fuel production processes. 2. Determination of the Cellulosic Composition of Landfill Biogas In order for fuel s produced from landfill biogas as a feedstock to qualify to generate D Code 3 or 7 (cellulosic) RI Ns, the renewable fuel must be derived from cellulosic materials and must meet a 60% GHG emissions reduction threshold, as described in the following section s. In this section, we discuss our determination that biogas derived from landfills is derived from cellulose, hemicellulose or lignin. 14 U.S. Environmental Protection Agency. 2013.

30 CAA 211(o) specifies “separated yard waste or food waste” as a t ype of renewable biomass, and in the March 2010 RFS final rule, EPA stated: As a result of the intermixing of wastes, the fact that biogas is formed onl y from the biogenic portion of landfill material, and the fact that landfill material is as a practical matter inaccessible for further separation, EPA believes that no further practical separation is possible for landfill material and biogas should be considered as produced from separated yard and food waste for purposes of EI SA. The March 2010 RFS final rule stated that all landfill - derived bioga s was therefore eligible to generate RINs. An in - depth study

of methane production from different chemical components of municipal solid waste found that roughl y 90% of the methane generated in landfills derive d was from cellulose and hemicellulose. 15 Accordingl y, EPA is proposing to classify renewable fuels produced from landfill biogas as derived from cellulose, hemicellulose or lignin. This determination is discussed in more detail in a memo to the docket. 16 Consistent with the discussion in the section above , “Approving Cellulosic Volumes from Cellulosic Feedstock”, we are classifying all of the biofuel volume produced from landfill biogas as cellulosic in origin.

31 Therefore the entire volume of renewable fuels using landfill biogas as a fee dstock will be eligible to generate cellulosic RI Ns (D - Codes 3 and 7) if the fuel also meets the required 60% GHG emissions reductions. EPA invites comment and data on the cellulosic component of biogas. 3. Fuel Production

– General Considerations Landfills currentl y treat their methane in one of several ways. Municipal solid waste (MSW) landfills designed to collect at least 2.5 million megagrams (Mg) and 2.5 million cubic meters of waste and emitting at least 50 Mg of non - methane organic compound s per year are required b y EPA regulations to capture and control their biogas. 17 These large, regulated landfills represent a small percentage of all landfills by number but are responsible for the majority of biogas emissions from landfills. To comply w ith the regulations, these landfills must at a minimum combust their biogas in a flare, converting the methane to carbon dioxide, a less potent GHG . They

may also use it to generate electricity from combustion of the methane, in which case, the elec tricity produced may displace electricit y from other sources ( such as gas fired power plants ) once it enters the grid. If displacing other sources of electricity that on average have greater GHG emissions, landfills that generate electric ity may reduce GHG emissions and are using the “best practices” in the industry . 18 Many smaller, unregulated landfills do not collect their biogas, and this methane is “vented” to the atmosphere. In 20 10 , 2 9 % of the methane generated at landfills was flar ed and 2 9 % of the methane was used to

32 generate electricity . 19 Accounting for the 25% average collection efficiency of biogas collection sy stems, 20 we estimate that approximately 38% of the methane generated is derived from landfills that flare their gas and another 38% is derived from landfills with gas - to - electricity projects . By

mass balance, this suggests that 2 4 % of the landfill methane generated is from landfills that vent their methane. In our lifecycle GHG analy sis of these biofuels we need to consider what would have happened to the landfill gas if it was not used to produce transportation fuels. This is the baseline for comparison to calculate the GHG impacts of the fuels in question . Once we have chosen a baseline for comparison, we propose to treat biogas from all landfills the same regardless of how the biogas is processed at that landfill. This approach is consistent with how we have treated the implementation of advanced technologies for all biofuels producers. For the landfill gas - to - electricity pathway we use landfills that flare their biogas as the baseline GHG emissions with which we compare scenarios involving production of electricity from the landfill biogas. We chose this baseline because these landfills are the ones most likely to convert to gas - to - energy projects, since they

already have gas collectio ns sy stems in place. They are also the ones most likely to be the alternative to gas to energy projects since these projects will likely

go into larger landfills that are required by regulation to collect and treat the biogas. We expect that small, unregulated landfills would be unlikely to generate enough biogas

33 to justify collecting it for conversion to renewable fuels. Furthermore, we expect that the capital costs for such small landfills would preclude them from making such changes. However, if such small landfills were to capture and use their biogas in transportation fuels, this would result in significantl y greater reductions in GHG emissions at each landfill than assumed for landfills already capturing biogas because of the decrease in methane re lease, so that biofuels produced from such facilities would easily meet the required emissions reduction thresholds. Since landfills that currentl y have gas - to - energy projects in place at one point either replaced flaring with a gas - to - energy

project or i nstalled a gas - to - energy project as an alternative to the minimal compliance route of flaring, we are proposing to treat the emissions from these landfills compared to the same flaring baseline. We show lifecycle results calculated using alternative basel ines and discuss our choice of baseline in more depth in a memo to the docket. 21 We invite comment on our baseline assumptions for the electricity pathway . If commenters believe a different baseline is appropriate, EPA specificall y invites the submission of data supporting this alternative baseline . For gas to liquids projects we also use landfills that flare their biogas as the baseline GHG emissions with which we compare scenarios involving production of gas to liquids , for the same reasons outlined above. We further consider that landfills that have already invested the capital to generate electricity are unlikel y to stop doing so in order to generate liq uid fuels from the biogas, which would require considerable additional capital investments. These facilities are therefore an unlikel y baseline for the pathways generating renewable diesel and naphtha. We

If commenters believe a different baseline is appropriate, EPA specificall y invites the submission of data supporting this alternative baseline. 4. Fuel Production for Renewable Electricit y Landfills can generate electricity b y combustion of the methane in their biogas. Generating electricit y at landfills requires collection of the biogas (using wells, piping and blowers), purification and compression of the biogas and electricity generation. Most landfills use internal combustion engines to generate the electricit y, but a significant proportion also use gas or steam turbines or combined cycle s ys tems. Once generated, the electricity enter s the electrical grid. In determining the lifecycle GHG anal ys is of renewable electricit y, we examined two main factors. The first involved determining b y how much emissions at the landfill (from flaring) would change upon installation of a gas - to - energy project. For this calculation, we used emission factors from the GREET model . 22 The second involved calculation of the decrease in GHG emissions caused by powering the gas blowers already in use with biogas - derived electricit y rather than grid elec tricit y upon installation of a gas - to - energy project. This calculation used data from the EPA L andfill Methane Outreach Project (LMOP). 23 For each factor, we needed to first calculate how much electricity could be generated and delivered to the

Unlike traditional transportation fuels, there are no GHG emissions involved in transportation or distribution of renewable electricit y (distribution losses are accounted for a bove), nor are there an y t ailpipe emissions from the direct use of the fuel. Therefore, the only emissions considered are those from production of the fuel, as outlined in Table V.B. - 2. The total GHG emissions for conversion from flaring to a gas - to - ener gy project are 1 2 kg CO 2 - eq/mmBtu electricit y, or 4 kg CO 2 - eq/mmBtu fuel equivalent. Compared with the gasoline baseline GHG emissions of 98 kg CO 2 - eq/mmBtu, these projects would be accompanied by an 8 7 % reduction in GHG emissions when normalized per mmBt u electricit y. Accounting for the improved efficiency of EV drivetrains increases the GHG emissions reductions to 9 6 %. Renewable electricit y therefore meets the statutory

baseline of 60% reductions in GHG emissions relative to the gasoline baseline an d qualifies as a cellulosic biofuel. EPA invites comments on the assumptions and calculations of GHG emission s related to renewable electricity from landfill gas. 5. Fuel Production, Transport and Tailpipe Emissions for Renewable Diesel and Naphtha Renewable diesel and naphtha can be made from landfill biogas b y a combination of methane reforming and the Fischer - Tropsch gas - to - liquids (GTL) process. For methane reforming, the biogas must first be purified and then be reformed to create sy nthesis gas , known as “s yn gas”, which is composed of a mixture of carbon monoxide and hydrogen gas. This process may

occur via either steam methane reforming or autothermal reforming. The s yn gas is next purified and then sent to a Fischer - Tropsch (F - T) s ys tem in wh ich the carbon monoxide and*** E.O. 12866 Review

38 hydrogen are combined in the presence of a catalyst to form a range of hydrocarbons. This reaction produces relatively short - chain (naphtha), medium - length (diesel) and long - chain (wax) hydrocarbons. The wax can subsequentl y b e upgraded by hydroprocessing to form naphtha and diesel fuels. The different products are then separated b y simple distillation. Heat generated b y the reaction can be used to preheat gases in the s ys tem and to generate electricity for use in the sy stem or for export. Unconverted s yn gas from the F - T process and fuel gas from hydroprocessing can also be combusted to generate electricity . GTL plants may have substantially

different lifecycle GHG impacts depending on whether they upgrade their waxes and wh ether they

generate electricity

as a side product of the reaction. Electricity generation can add to the capital costs of a facilit y but also greatly reduces the lifecycle GHG emissions of a plant. In determining the lifecycle GHG impacts of GTL fuels, we considered two main factors: on - site emissions at the landfill and upstream emissions from electricity production to power the plant. Additionally , a facility that produced wax was assigned a co - product credit for the wax generated. We did the calculations assuming the facility did not generate any

electricit y and then calculated what fraction of their electricity demands they

would need to generate internally to meet the 60% emissions reduction threshold to qualify for cellulosic RI

Ns. To determine the lifecycle GHG emissions, we used confidential business information (CBI) data provided in a petition submitted to EPA. This process did not involve upgrading of wax to liquid fuels. For this scenario, we used the supplied information about inputs of biogas, outputs of fuel and co - product and electrical demand for the lifecycle analy sis. We first*** E.O. 12866 Review

39 determined how man y GHG emissions would be avoided on - site at the landfill by changing from the baseline scenario of flaring to collecting the biogas for conversion to liquid fuels. This calculation was similar to that described above for renewable electricity and relied on values from GREET 26 for the emissions factor for flaring. To calculate the emissions from electricity required b y the process , we used the emissions factors for average U.S. electrical production used in the RFS2 final rule. To assign a co - product credit to the fuels, we assumed that the wax produced during the Fischer - Tropsch process would enter a market in which it woul d displace wax derived from petroleum. To determine the effects of such a displacement on GHG emissions, we used data from a model b y the Department of Energy ’s National Energy Technology

L aboratory

(NETL) 27 for the yi elds and GHG emissions attributable to wax production from petroleum feedstock. These values onl y include production emissions and do not include an y em issions from combustion of the wax in, for example, candles because we do not have information about what fraction of wax is combusted. If c ombustion emissions were included, the co - product credit would be even larger. The global wax market is growing, with demand expected to outpace supply in the next few y ears. 28 As such, it is unlikely that F - T waxes would in reality displace petrole um - derived waxes. Instead, waxes from both sources are likel y to be used in parallel to fulfill demand, and such waxes would replace an y substitutes that might be used to fill the gap between suppl y and demand. The nature of these alternatives is present ly unknown to EPA, as

40 are their lifecycle GHG emissions. As an alternative to assigning a displacement credit, we could allocate emissions to the waxes along with the renewable diesel and naphtha products. In this case, the co - product credit disappears b ut total fuel production emissions decrease to 30 kg CO 2 - eq/mm Btu, leading to overall GHG emissions reductions of 68%, considerabl y lower than if we assign a displacement credit. However, we chose to use the displacement approach as a conservative way

to account for the wax co - product. We welcome comment regarding what kinds of materials these new waxes might replace, as well as how to best account for them in our lifecycle GHG analy sis. The results of this anal ys is are shown on the “Fuel Producti on” line of Table V.B. - 3, and the assumptions and calculations are discussed in more detail in a memo to the docket . 29 Emissions from electricity production used to power the F - T plant is the greatest contributor to the overall fuel production emissions. Inaddition to emissions from fuel production, there were minor GHG emissions attributable to fuel transport and tailpipe emissions of non - CO 2 GHGs (Table V.B. - 3). Overall, renewable diesel and naphtha produced from landfill biogas via this process showed 5 2 % and 5 1 % reductions in GHG emissions, respectivel y, relative to the diesel or gasoline baseline (Table V.B. - 3). These fuels would therefore qualify as advanced biofuels but not qualify

as cellulosic biofuels. However, if the facility produced roughl y 15% of its process electricit y internally, using either waste heat from the reaction or combustion of unreacted chemicals, emissions from purchased electricity would drop enough to reach the 60% GHG reduction threshold, qualifying these fuels as cellulosi c.

41 production of these biofuels (without internal production of electricity) fall so close to the 50% threshold to qualify

as advanced biofuels, the assumptions used to make the calculations are especiall y important and could potentially change the classification of these fuels. Accordingly , we request comments about the assumptions and values used in the calculations, which are detailed in a memo to the docket 30 . In particular , we request comment about the estimate for the on - site GHG emissions at the Fischer - Tropsch facility . Data regarding fugitive emissions from Fischer - Tropsch facilities using methane as a feedstock appear to be limited, however, the GREET model assumed a loss factor of 1.0000 for the production of F - T diesel, indicating their estimate that no methane is lost during this process. S everal studies mentioned emissions from the steam methane reforming of natural gas to produce hydrog en, and we assumed emissions would be similar from a Fischer - Tropsch facility using steam methane reforming. Two of these studies 31 , 32 found or estimated that losses of methane from such facilities were negligible, agreeing with the GREET estimate. Accordi ngl y, we assumed no emissions of methane from F T facilities. H owever, another study 33 estimated losses of 0.125% of the natural gas processed. Using this last value, the GHG emissions reductions for renewable diesel and naphtha would decrease to 4 9 % for both fuels , meaning that the biofuels would no longer qualify as advanced

43 emissions from such products. Based on this analy sis (not shown), these facilities should theoreticall y have GHG emissions that are as low as or lower than those calculated above. For this reason, we believe that the lifecycle anal ys is shown above is a reasonable, if slightly conservative, represent ation of expected landfill biogas - to - liquids projects. We accordingl y classify all renewable diesel and naphtha produced via the F - T process from landfill biogas as advanced biofuel. The lifecycle anal ys is for these fuels considered that the renewable di esel product produced from the Fischer - Tropsch process would be used as conventional diesel fuel. EPA does not have sufficient information to evaluate the lifecycle greenhouse gas emissions for jet fuel or heating oil produced from landfill biogas using the Fischer - Tropsch process. Because the lifecycle anal ys is results for this process fell so close to the threshold for advanced biofuels, in this pathway , we are proposing to only allow renewable diesel for use as conventional diesel fuel to qualify under the RFS program. We invite comments and supporting data about whether we should also allow jet fuel and heating oil produced from landfill biogas to qualify. Our lifecycle analy sis showed that if the evaluated facility meets approximately

15% of its electricit y demand with internally produced electricity from eligible sources , it will meet the 60% threshold to qualify

as cellulosic. Because other facilities are likel y to be somewhat different, and because this analy sis relies on a number of assumptio ns, we are using a slightly more conservative threshold of 20% of electrical generation. Accordingl y, we are proposing that

44 if a biogas - to - liquids facility produces at least 20 percent of its process electricity internally

as discussed above, these biofu els will qualify as cellulosic.

Facilities that can supply

data that demonstrate they meet the 60% GHG emissions reduction threshold without production of 20% electricity are welcome to petition the EPA individually under section 80.1416. EPA invites comment and data on the GHG emissions associated with landfill biogas renewable fuel pathway s. We also welcome comment on the methodology and assumptions underlying this analy sis.

Amendments related to Biogas 1. Changes Applicable to the Revised CNG/LNG pathway from Biogas In the existing RFS2 regulations, an approved fuel pathway in Table 1 to section 80.1426(f)(1) allows biogas from landfill gas, manure digesters or sewage treatment plants to qualify as an a dvanced biofuel and generate a D code of 5 for the biofuel produced under the RFS2 program. Since the promulgation of the final rule, we have received many requests about*** E.O. 12866 Review

45 what fuel qualifies under this pathway , including: 1) the renewable fuel t yp e that is qualified under the term “biogas,” 2) what are the eligible sources of biogas, 3) what company along the production chain of biogas from generation to end user is considered the producer that qualifies to register under this pathway and generate RINs, and 4) what are the contract requirements to track the biogas from generation to end use. In response, EPA is proposing in this rulemaking to amend the existing biogas pathway in Table 1 to section 80.1426(f) by changing the renewable fuel ty pe in the pathw ay

from “biogas” to “renewable compressed natural gas (renewable CNG) and renewable liquefied natural gas (renewable LNG)” and to replace the feedstock t ype of “landfills, manure digesters or sewage waste treatment plants” with “biogas from landfills , waste treatment plants or waste digesters.” We are also proposing to revise the definition of biogas and add definitions for CNG and LNG to section 1401 to provide additional clarity . In addition, we are proposing to revise and add new contracting, registration, reporting and recordkeeping requirements along the production chain. Furthermore, we are specifying which company along the production chain is considered the “producer” and elig ible to generate RI Ns under the RFS2 program. These proposed compliance requirements are applicable to this revised CNG/L NG pathway , and all the newly proposed pathways for renewable fuels produced from landfill gas in this rulemaking. The details of the p roposed new requirements for contract, registration, reporting and recordkeeping are discussed below in the section titled “Changes Applicable to All Biogas - Related Pathway s for RIN Generation.”*** E.O. 12866 Review

46 The existing biogas pathway in Table 1 to section 80.1426(f) refers to “biogas” as the renewable fuel ty

pe and “landfills, manure digesters and sewage waste treatment plants” as the feedstock. Companies have raised questions whether the term “biogas” in this pathway could refer to the unprocessed or raw gas from the landfills, manure digesters or sewage treatment plants, or processed “biogas” that has been upgraded and could be used directl y for transportation fuel or as an ingredient in the production of transportation fuel or as an energy source used in the prod

uction of transportation fuel, or other fuel t ypes that can be produced from the raw biogas either through a ph ys ical or chemical process (such as CNG, L NG, renewable electricit y, renewable diesel or naphtha). The companies further inquire if the various forms of biogas discussed above could qualify under this pathway , and therefore be eligible for RI N generation under the RFS2 program. We agree that the term “biogas” in this pathway is used broadl y in the industry to refer to various raw and processed forms of the biogas from various sources. However, under the existing requirements in sections 80.1426(f)(10) and (11), only biogas that is used for transportation fuel can qualify as renewable fuel f

or RIN generation under the RFS2 program. We believe the stipulations in sections 80.1426(f)(10) and (11) are clear that biogas used for non transportation fuel purposes, such as an energy source for providing process heat would not qualify under this bi ogas pathway for RIN generation. Similarly , raw biogas would also not qualify under this pathway

since unprocessed biogas cannot be used as transportation fuel. With regard to the fuel t ypes that can be produced from the raw biogas such as CNG, LNG, rene wable electricit y, renewable diesel, or naphtha, the pathway determinations for the final rule did not account for all factors relevant for the additional fuel ty pes such as renewable electricit y,*** E.O. 12866 Review

47 renewable diesel or naphtha produced from the raw biogas through a chemical process. Therefore, renewable electricity , renewable diesel and naphtha produced from biogas do not qualify under the existing pathway . 37 For CNG and L NG, we concluded that these ty pes of fuels were close enough to the phy sical molecules of biogas since these fuels only go through a phy sical process in which the biogas is compressed or liquefied, and that because CNG and LNG can be used di rectl y for transportation purposes, thus meeting the provisions in sections 80.1426(f)(10) and (11), we concluded that CNG and LNG could qualify under the existing pathway . For the reasons discussed above, we are proposing to amend the existing biogas pathway to clearl y state that only CNG and LNG produced from biogas from landfills, waste treatment plants and waste digesters, and used as transportation fuel , qualify as a cellulosic or advanced biofuel for RIN generation under the RFS2 program. The curre nt regulations provide a pathway for biogas produced from a bio - digester which uses manure. We are also proposing to expand the ty pe of materials that may

be used to produce CNG/L NG in a digester to include animal wastes, biogenic waste oils/fats/greases, separated food and yard wastes, and crop residues. These feedstock sources are already eligible in the existing rules pathway s and therefore should reasonably be added to the bio - digester pathway . We are doing so in response to a petition request to gen erate RINs from biogas which is produced from bio - feedstock sources in addition to the already allowed manure, either individually

or in combination with manure in a bio - digester. As with other L CA pathway s

48 using these materials, EPA is proposing to assum e these waste materials do not have emissions associated with feedstock production, and therefore qualify as cellulosic or advanced renewable fuels when used to produce CNG/LNG. To provide improvement for this revised pathway , we are proposing to revise the definition of biogas and add new definitions for renewable CNG and renewable LNG to section 80.1401 to read as follows: Biogas means a mixture of hydrocarbons that is a gas at 60 degrees Fahrenheit and 1 atmosphere of pressure that is produced through the conversion of organic matter. Biogas includes landfill gas, gas from waste digesters, and gas from waste treatment plants. Waste digesters include digesters processing animal wastes, biogenic waste oils/fats/greases, separated food and yard wastes, and crop residues, and waste treatment plants include wastewater treatment plants and privately owned treatment works . Renewable compressed natural gas (“renewable CNG”) means biogas as defined in this section, that is processed to the standards of pipeline natural gas as defined in 40 CFR 72.2 and that is compressed to pressures up to 3600 psi . Only renewable CNG that qualifies as renewable fuel and is used for transportation fuel can g enerate RI Ns. Renewable liquefied natural gas (“renewable LNG”) means biogas as defined in this section, that is processed to the standards of pipeline natural gas as defined in 40 CFR 72.2 and that goes through the process of liquefaction in which the biogas is cooled*** E.O. 12866 Review

49 below its boiling point and weighs less than half the weight of water so it will float if spilled on water. Onl y renewable LNG that qualifies as renewable fuel and is used for transportation fuel can generate RINs. 2. New Re gistration (Contract Requirements) for Renewable Electricity and Fuels Produced from Biogas that Qualify as Renewable Fuel and that are Registered for RIN Generation The regulations as currently written allow a producer of biogas or renewable electricity 38 that qualif

ies as renewable fuel and has an approved fuel pathway in Table 1 of section 1426(f)(1) to register and generate RINs for the volume it produces under the RFS2 program. We modified the existing regulations to state that biogas is the feedstock used to produce renewable fuel, as described above. The revised regulations in sections 1426(f)(10) and (11) detail the requirements for distribution and tracking for renewable electricity and biogas used to produce fuel that qualifies as renewable fuel that can either be distributed in a dedicated pipeline or transmission line or distributed in a shared pipeline or power grid s ys tem. The purpose of these requirements is to provide EPA assurance and verification that onc e the biogas or renewable electricit y is put into a dedicated or shared distribution sy stem that in fact an equivalent volume of biogas or renewable electricity will be used for transportation fuel , and for no other purposes. The requirements are also meant to address concerns of double counting of the biogas or renewable electricit y, especiall y in situations that the biogas or renewable electricity is placed in
38 EPA notes that currentl y, producers of re newable electricit y that may qualify as a renewable fuel cannot register and generate RINs because there is no approved pathway in Table 1 for renewable electricit y from any approved feedstock. But in the event that an approved pathway for renewable electricity

is added to Table 1, EPA notes there are existing requirements such as tracking and distribution requirements recordkeeping and reporting that are applicable for the registration of renewable electricity for RIN generation.*** E.O. 12866 Review

50 or loaded onto shared distribution sy stems that contain gas or electricity from non - renewable bi omass sources. EPA intended to require producers to submit the information and contract requirements in sections 1426(f)(10) and (11) as part of the registration requirements for renewable electricit y and renewable fuels produced from biogas that are used for transportation 39 fuel , but had not done so in the prior rulemakings. Therefore, as a natural outgrowth of the regulations for implementation and compliance purposes, we are proposing in this rulemaking to incorporate the requirements in sections 1426(f )(10) and (11) as part of registration requirements for producers of renewable electricit y and renewable fuels produced from biogas that qualify as renewable fuel under the regulations under section 1450(b)(1)(iv)(C). Section 1426(f)(11)(ii) of the regulations requires that, in order for renewable fuel made from biogas withdrawn from a commercial distribution sy stem for use as a transportation fuel to generate RINs, the biogas introduced into the sy stem must have been added to a common carrier pipeline. We propose to add a similar provision to section 1426(f)(11)(i) for renewable electricit y, requiring a company to load the renewable electricity to a power grid shared b y the second compan y that withdraws the electricit y, such that the two companies must be physicall y connected to the same grid or located within the same area. EPA is requesting comments about whether the other existing requirements in sections 1426(f)(10) and (11) for renewable electric ity and renewable fuels from biogas used for transportation fuel are sufficient to provide assurance and verification for the following situations. First, do the proposed requirements provide assurance and verification that the same 39 Distribution and registr ation requirements for biogas used as process heat, and not for RIN generation as renewable fuel is detailed in Section 1426(f)(12) and 1450(b)(1)(iv), respectivel y.*** E.O. 12866 Review

51 amount of biogas or re newable electricit y is in fact delivered to the renewable fuel producer or end user who will actually use the biogas or renewable electricity for transportation purposes? If the proposed requirements are not sufficient, what alternative requirements shoul d be considered? Second, are the proposed requirements sufficient to ensure that double counting does not occur, e.g., to ensure that the biogas or renewable electricity once it is loaded into a shared pipeline or power grid is not sold to multiple client s or for purposes other than for transportation purposes? Similarly , if the proposed requirements are not sufficient, what alternative requirements could be considered to ensure double counting does not occur ? 3. Changes Applicable to all Biogas Related Pathways for RIN Generatio n As discussed above, we have had man y inquiries related to the “biogas” pathway, specificall y regarding contract requirements for tracking the biogas through the distribution sy stem and regarding what compan y along the production chain is considered the “producer” and eligible to generate RINs under the RFS2 program. Inthis rulemaking, we are proposing to revise and add new requirements for contracts to track the biogas as it moves into and out of the distribution sy stem, as well as provisions on registration, reporting and recordkeeping. These proposed amended requirements are applicable to all pathway s related to biogas that are eligible for RIN generation that are existing or proposed in this rulemaking. In response to the question of what compan y is considered the producer of renewable fuel and eligible to generate RI N s under the RFS program, we propose to clarify who is the “producer” for renewable CNG/L NG and renewable electricit y. We propose that the “producer”*** E.O. 12866 Review

52 of renewable CNG/LNG is the company that compres ses or liquefies the gas and distributes the CNG/L NG for transportation fuel, and for renewable electricit y, the “producer ” is the company that distributes the electricity for use as transportation fuel . There are two registration situations that this clarification will address: (1) the owner/operator of a landfill collects biogas and processes it to a qualifying renewable CNG/LNG/electricit y for transportation use and distributes on site and (2) the owner/operator of a landfill collects biogas and it is p rocessed into a qualifying renewable CNG/L NG/electricity

for transportation use by a contracted third part y and distributed by

this third party . The party that converts the biogas to renewable CNG/L NG/electricit y and distributes for use as a transportation fuel is responsible for RIN generation. Under the first scenario, the registration package, including the engineering review, would cover the biogas source (landfill, waste digester, etc.) as well as the distribution that is occurring on site. Under the the second scenario, the registration package, including engineering review, would cover the biogas source (landfill, waste digester, etc.) the pipeline (common carrier or dedicated) and each distribution facility. By requiring the part y that is responsible for conversion and distribution to register as the RIN generator, we can prevent RI Ns from being generated for a batch or renewable CNG/LNG/electricity prior to use as a qu alifying transportation fuel. For any of the fuels, the company designated as the “producer” will be required to register under the RFS2 program. We seek comment on our proposed definition of producer regarding renewable CNG/LNG and renewable electricit y . W e acknowledge that the process train from raw biogas to the final transportation fuel is complex, and may

include many

companies and processing steps from the point when the raw biogas is withdrawn from its source (such as landfills, waste digesters, waste treatment plants),*** E.O. 12866 Review

53 processed and converted into biofuel and distributed to consumers. Alternatively , the fuel may be cleaned at a bio gas facility to pipeline quality

specifications for distribution, and then withdrawn from the commercial pipeline to be processed further at another production facility into renewable CNG/LNG or renewable electricity . Due to the complexity of the many entities potentially

inv olved in this process train, we are proposing that the company deemed as the “producer” under the qualifications described above also be responsible for providing all the required information and supporting documentation in their registration, reporting an d recordkeeping to track and verify the information from point of extraction of the raw biogas from its original source, and all the processing steps and distribution in between, to the last step where the actual fuel is used for transportation purposes. Inthe engineering review report required for registration, the producer must include documentation that the professional engineer performed site visits at each production facility , including the biogas facility and the facility

that produces the final fue l (if these are not the same facility). The producer must also review and verify all related supporting documents such as design documents, calculations, regulatory permits, and contracts between facilities that track the raw biogas from the point of with drawal from its source, the various injection/withdraw points into the distribution pipeline, the various production facilities, and the final step for use as transportation fuel. We believe these requirements will ensure that producers will perform due d iligence that the fuel for which they generate RINs under the RFS2 program are in compliance with all the regulatory requirements for renewable fuel. The proposed registration, reporting and recordkeeping requirements are in sections 80.1426(f), 80.1450, 80.1451 and 80.1454 in this rulemaking. Additional changes regarding the contract requirements for distribution of the biogas in shared commercial pipelines are discussed below, and can be located in sections 80.1426(f)(10), (11), and (13).*** E.O. 12866 Review

The additi onal registration, recordkeeping and reporting requirements are discussed in detail below. For the proposed fuel pathway s for cellulosic diesel and cellulosic naphtha produced from landfill gas, we are proposing to require the renewable fuel production facility to produce a minimum of 20 percent of the process electricity used at the facility

on a calendar y ear basis , from raw landfill gas , waste heat from the production process, unconverted sy ngas from the F - T process, fuel gas from the hydroproc essing or combined heat and power (CHP) units that use non - fossil fuel based gas or other renewable sources . We propose that if less than 20 percent (on an annual average basis) of process energy comes from one of these alternative sources, then no cellul osic RI

Ns can be generated for that year.

40 Refer to preamble discussion for these various biogas pathway s in section titled, “L ifec ycl e Greenhouse Gas Emissions Analy sis for Renewable Electricit y, Renewable Diesel and Naphtha Produced from Landfill Biogas.”*** E.O. 12866 Review

55 For the renewable fuel production facility applying to use the proposed fuel pathway with the requirement to internally produce at least 20 percent of the total amount of process electricit y used at its facility , we are proposing the facility submit to EPA the information described below to demonstrate compliance with this requirement. For registration purposes, we are proposing that producers submit the following additional information in the process fuel supply plan that is currentl y required as part of the registration process (estimated summaries are to be reported on an annual/ calendar ye ar basis):

- Estimated amount of total electricit y used at the facility

- Estimated amount of total electricit y purchased for th e facility

- Estimated amount of total renewable electricity produced on - site, including the source of the energy

and the equipment and/ or process used to generate the renewable electricit y

- Calculation that verifies the facility meets the specified 20 percent minimum electricit y production requirement based on the reported total amount of electricity used at the facility , total amount of electricit y purchased, and total amount of renewable electricit y produced For reporting purposes, we are proposing for prod ucers to submit the following additional information as part of their existing quarterl y and annual reporting obligations (reported amounts should be provided as monthly summaries on an annual/ calendar ye ar basis, and must be obtained from a utility meter that is continuously measured):

The regulatory requirements for registration, reporting and recordkeeping as discussed in this proposed rulemaking can be located in the following applicable regulatory sections 80.1450, 80.1451 and 80.1454, respectively . D. Amendment to the Definition of “Crop Residue” and Id entification Corn Kernel Fiber as a Crop Residue We propose to amend the definition of “crop residue” so that this category includes only feedstock sources that are determined b y EPA would not result in a significant increase in direct or indirect GHG emissions. “ Crop residue” is the biomass left over from the harvesting or processing of planted crops from existing agricultural land and an y biomass removed from existing agricultur al land that facilitates crop management (including biomass removed from such lands in relation to invasive species control or fire management), whether or not the*** E.O. 12866 Review

57 biomass includes any

portion of a crop or crop plant. Biomass is considered crop residue on ly if the use of that biomass for the production of renewable fuel has no significant impact on demand for the feedstock crop, products produced from that feedstock crop, and all substitutes for the crop and its products including the residue, nor any othe r impact that would result in a significant increase in direct or indirect GHG emissions. EPA is amending the definition of “crop residue” to confirm the meaning of the term “left over” in the text of this definition. The phrase “left over” in our original definition of “crop residue” is meant to indicate that the use of a residue as a biofuel feedstock should not increase demand for the crop it is derived from, should not induce further crop production, and should not result in additional direct or indirect GHG emissions. The residue must come from crop production or processing for some other primary purpose (e.g., refined sugar, corn starch ethanol), such that the crop residue is not the reason the crop was planted. The residue must also come f rom existing agricultural land, the exact definition of which is laid out in our current regulations that define “renewable biomass”. 41 Further, the residue should generall y not have a significant market in its own right, to the extent that removing it fro m that market to produce biofuels instead will result in increased GHG emissions. EPA is seeking comments on this revision to the crop residue definition. EPA invites all comments regarding this revision, but specificall y invites comments regarding the p otential for the revision to create a significant shift in direct or indirect GHG emissions and what ought to constitute a “significant” increase or decrease in GHG emissions in the context of this definition .

58 EPA has previously

identified several potent ial feedstocks that we believe meet the criteria of crop residue. Table IV.D. - 1 lists feedstocks which may fit the definition of crop residue. Most of these feedstocks were discussed in the final RFS2 rulemaking. For example, EPA anal yz ed the agricultur al sector GHG emissions of using corn stover for biofuels in the final RFS2 , and found that fuel produced from this feedstock met the 60% GHG reduction threshold for cellulosic biofuels. Since the direct and indirect impacts of citrus residue, rice straw, and wheat straw removal were expected to be similar to corn stover, EPA also applied the land use change impacts associated with corn stover to citrus residue, rice straw, and wheat straw . Based on that anal ys is, EPA found that fuels produced from citrus residue s , rice straw, and wheat straw also met the 60% reduction threshold. EPA further determined that fuels produced from materials left over after the processing of a crop into a useable resource had land use impacts sufficiently

similar to agricultural residues to also meet the 60% threshold. EPA specificall y cited bagasse left over from sugarcane processing as an example of this ty pe of residue. EPA is seeking comment on whether the feedstocks on this list should be considered crop residues , if these feedstocks would have similar direct and indirect impacts as corn stover , and whether additional feedstocks should also be included in this list.

59 Citrus Residue D - 3 Cellulosic biofuel Rice Straw D - 3 Cellulosic biofuel Wheat Straw D - 3 Cellulosic biofuel While EPA believes that, under current conditions, generation of RINs for batches of renewable fuel produced from the feedstocks listed in Table IV.D. - 1 above would not result in a significant increase in direct or indirect GHG emissions , we also acknowledge the potential for this assessment to change in the future based on unforeseeable factors. For example, some new use for one of these products could be developed which would change our assessment that the feedstock has no significant market in its own right . Further, it is possible that, at some point in the future, large enough quantities of renewable fuel could be produced from one of these fuels to create demand pull for the feed stock, potentially altering the behavior of producers of the residue and leading to significant increases in direct or indirect GHG emissions. To our knowledge, this is not currentl y the case for an y of the feedstocks listed above. However, EPA will cont inue to monitor RI N generation from fuel produced using each of these feedstocks and the general use of these feedstocks in the marketplace. We further reserve the right to revisit the status of an y feedstock that we have determined qualifies under the crop residue pathway . S hould any

feedstock qualifying as a crop residue be used to generate significant quantities of ethanol in the future, or should a significant market emerge for the product such that there is demand pull for it in excess of the demand pull for the planted crop from which it is a derived by product, we will revisit whether that feedstock should remain under the crop residue pathway or be subjected to further scrutiny .

60 potential for significant demand pull to emerge for the feedstocks we are proposing to consider as crop residues. We also propose that this definition of “crop residue” includes corn kernel fiber. Corn k ernel fiber is not specifically mentioned as a t ype of crop residue under the Renewable Fuel Standard (RFS2) regulations. Per the RFS2 definition of “crop residue”, EPA must evaluate whether corn kernel fiber is “left over from the harvesting or processin g of planted crops” and that it has no “impact that would result in a significant increase in direct or indirect GHG emissions” for this feedstock to qualify as a residue. One additional consideration in the classification of corn kernel as a crop residue is the fact that some amount of corn starch might still adhere to the corn kernel after separation. The percentage of contamination will vary , but as much as 20% of the final fuel could be derived from corn starch. By

definition, corn starch ethanol c an only qualify as a renewable fuel, not as an advanced fuel. However, our current regulations state that “producers and importers may disregard an y incidental, de minimis feedstock contaminants that are impractical to remove and are related to customary feedstock production and transport ”. 42 Therefore, EPA is seeking comment on whether the definition of crop residue should be amended to explicitly exclude the corn starch component. EPA also invites comment on how RI Ns should be allocated for ethanol derived from corn fiber. EPA has existing regulations that define procedures for generating RINs from batches of fuel that contain multiple feedstocks, including feedstocks that generate RI Ns of 42 See specifically § 80.1426 (f) (1) .*** E.O. 12866 Review

61 different D codes. 43 We believe that these regulations provide sufficient guidance to producers and importers regarding how to assign RINs to batches of renewable fuel that can be described by two or more pathway s (e.g., corn starch ethanol and co rn kernel fiber ethanol). However, we invite comment on the sufficiency of these regulations with regards to the assignment of RINs to coprocessed batches of corn starch ethanol and corn kernel fiber ethanol , including whether producers have the technolog ical capability to adequately

demonstrate volume produced under each pathway . To determine whether the use of corn kernel fiber to produce ethanol would lead to increased direct or indirect GHG emissions, EPA conducted a detailed assessment of the two major potential sources of emissions from this feedstock, namely effects on feed m arkets and effects on demand for corn. The proposed method of acquiring corn kernel fiber is to extract it from matter that is otherwise converted to dried distillers grains (DDG) during the dry mill corn ethanol process. Consequently , this anal ys is reli ed significantl y on the assessment of corn starch ethanol - derived DDG that was conducted for the RFS2 final rule, adjusting the anal ys is to account for the extraction of fiber from this product. The anal ys is also drew substantially on the available scient ific literature on low fiber DDG (LF - DDG), as well as the expertise of the U.S. Department of Agriculture. Potential producers also submitted important data to EPA that helped determine whether producing cellulosic ethanol from corn kernel fiber would res ult in a significant increase in GHG emissions. This included a full nutritional analy sis of LF - DDG for swine, poultry , and cattle.

43 See specifically § 80.1426 (f) (3) .*** E.O. 12866 Review

62 EPA found that extracting the fiber from corn matter used to produce standard DDG would not have a significant effect on feed markets. Processors who extract the fiber from corn produce a feed product known as LF - DDG, as opposed to standard DDG which retains the fiber. The scientific literature on LF - DDG animal nutrition has found that this product has at least equal , and perhaps even slightly superior, nutritional value for swine and poultry compared to standard DDG. 44 This means that, even though the phy sical volume of the DDG produced by ethanol plants using corn kernel fiber extraction technology will be somewhat smaller, its nutritional content for swine and poultry will be equivalent to or greater than their output without fiber extraction. Conversel y, LF - DDF is an inferior feed for cattle compared to standard DDG , since ruminants benefit from ingesting corn fib er in DDG . 45 Therefore, EPA expects swine and poultry producers to absorb the supply of LF - DDG, while the cattle and dairy industry will continue to consume standard DDG. With this dynamic in place, fiber extraction from DDG should not significantly

affec t feed markets, since there will be no reduction in the overall supply of DDG in terms of nutritional content nor will there be an y impact on aggregate demand for other animal feed sources. If enough corn ethanol producers adopt fiber extraction technolog y, LF - DDG could saturate swine and poultry demand and spill over into dairy and cattle feed markets. If a

63 situation arises where LF - DDG begin to replace standard DDG in cattle markets, this could lead to an increase in feed demand, most likely in the form of increased demand for fiber supplements in dairy and cattle feed. This could cause an increase in GHG emissions. If swine and poultry demand for LF - DDG becomes saturated, demand for standard DDG in the cattle and dairy industries should create suffici ent market incentives for the remaining corn starch ethanol producers to decide against adopting corn fiber ethanol production. EPA believes this will prevent a situation where there is insufficient supply of standard DDG in the cattle and dairy industrie s. However, as noted above, EPA reserves the right to reexamine corn kernel fiber as a feedstock in the future. EPA’s anal ys is indicates that producing cellulosic ethanol from corn kernel fiber is unlikely to increase overall demand for corn. In order to meet the definition of a crop residue, the source of corn kernel fiber must be a crop processing facility (e.g., a corn starch ethanol plant). A corn kernel fiber ethanol producer cannot purchase whole corn specificall y for the generation of corn fiber ethanol and still qualify their feedstock as crop residue. EPA is seeking comment on this analy sis. Based on our assessment, EPA proposes that corn kernel fiber would meet the definition of a crop residue, and qualify for Cellulosic Ethanol and A dvanced Biofuel (D - codes 3 & 5, respectivel y) R IN s under the RFS2. EPA is seeking comment on whether corn kernel fiber should be considered a crop residue.*** E.O. 12866 Review

64 E . Consideration of Advanced Butanol Pathway 1. Proposed New Pathway EPA is proposing to add a new pathway to Table 1 to section 80.1426 that allows butanol made from corn starch using a combination of advanced technologies to meet the 50% GHG emissions reduction needed to qualify as an advanced renewable fuel. This pathway applies to dry mill fermentation facilities that use natural gas and biogas from an on - site thin stillage anaerobic digester for process energy with combined heat and power (CHP) producing excess electricit y of at least 40% of the purchased natural gas energy of the facility (the proposed “advanced butanol pathway”). GEVO Incorporated submitted a petition requesting authorization to generate D - code 5 RI Ns for fuel produced through the GEVO butanol pathway . A petition is required because the prop osed process utilizes a high yi eld butanol fermentation process that is different from those anal yz ed as part of the RFS2 corn ethanol pathway s, and does not use the approved advanced technologies shown in Table 2 to section 80.1426 of the RFS 2 regulations. EPA’s evaluation of the lifecycle GHG emissions of the advanced butanol pathway under this petition request is consistent with EI SA’s applicable requirements, including the definition of lifecycle GHG emissions and threshold evaluation re quirements. It was based on information regarding GEVO’s production process that was submitted under a claim of Confidential Business In formation (CBI) b y GEVO on April 11, 2011. The information provided included the mass*** E.O. 12866 Review

65 and energy

balances necessary

fo r EPA to evaluate the lifecycle GHG emissions of the advanced butanol pathway . The lifecycle GHG emissions of fuel produced pursuant to the advanced butanol pathway were determined as follows: Feedstock production

– The advanced butanol pathway uses co rn starch as a feedstock. Corn starch is one of the feedstocks already listed in Table 1 to section 80.1426 of the RFS2 regulations. Since corn starch has already been evaluated as part of the RFS2 final rule, no new feedstock production modeling was req uired. The FASOM and FAPRI models were used to analy ze the GHG impacts of the feedstock production portion of the fuel’s lifecycle. The same FASOM and FAPRI results representing the emissions from an increase in corn production that were generated as par t of the RFS2 final rule anal ys is of the existing corn butanol pathway s were used in this anal ys is of the advanced butanol pathway . These results represent agriculture/feedstock production emissions for a certain quantity of corn produced. For the RFS2 analy sis, this was roughl y 960 million bushels of corn used to produce 2.6 billion gallons of fuel. We have calculated GHG emissions from feedstock production for that amount of corn. EPA does not believe the advanced butanol process for converting corn i nto butanol will materially affect the total amount of corn used for biofuels and modeled as part of the RFS2 final rule. Based on information provided b y industry , the technologies to produce corn butanol are primarily being targeted at retrofitting e xisting corn ethanol facilities, where the infrastructure to produce renewable fuels already exists and the*** E.O. 12866 Review

66 capital expenditures would be relativel y small. Therefore, the existing agricultural sector modeling analy ses for corn as a feedstock remain val id for use in estimating the lifecycle impact of renewable fuel produced using the advanced butanol pathway . The Agency is seeking comment on whether there is an y research to suggest that converting corn into an advanced butanol pathway

would materially

a ffect the total amount of corn used. GEVO provided, as part of the information claimed CBI, their process yi eld in terms of gallons of fuel produced per bushel of corn. Based on the data, GEVO’s process yi eld is slightly more efficient than the pathway s modeled as part of the RFS2 rulemaking. Therefore, compared to the corn butanol pathway s already anal yz ed, the GEVO process results in 0.93% more Btus of fuel produced for the same amount of corn feedstock. Fuel production

– The fuel production method included in this advanced butanol pathway involves the production of butanol from corn starch in a dry mill. The amount and ty pe of energy used in this anal ysis is different than production methods that were anal yz ed under the final rule. While there we re slight differences in the total amount of natural gas and electricity used in this analy sis, the main difference was the use of biogas and production of excess electricit y . To analyze the GHG impacts of the advanced butanol pathway , EPA utilized the same approach that was used to determine the impacts of processes in the RFS2 corn butanol pathway s. The amount and t ype of energy used was taken from GEVO’s mass balance & energy balance submitted to EPA. GEVO submitted energy data on natural gas and b iogas (in Btus) and*** E.O. 12866 Review

67 electricit y (in kWhs) inputs, as well as gallons of fuel produced. Biogas and natural gas are used in combination, while the RFS2 corn butanol anal yses only considered natural gas or biogas used independentl y, not in combination. The emissions from the use of energy were calculated by multiplying the amount of energy by emission factors for fuel production and combustion, based on the same method and factors used in the RFS2 final rulemaking. The emission factors for the diffe rent fuel t ypes are from GREET and were based on assumed carbon contents of the different process fuels. One area where EPA is soliciting comments is on the most appropriate energy content assumption to use for butanol (lower heating value). As part of this analy sis, EPA used the GREET value for the energy content of butanol, which is 99,837 Btus per gallon 46 . Differences in the measurement of the energy content of butanol can occur for a number of reasons including variations amongst isomers (t - butanol, n - butanol, isobutanol, and sec - butanol), and differences in testing methodologies. EPA is seeking comment on whether there are any reasons wh y EPA should change its assumptions and use a different energy content of butanol. The RFS2 corn butanol pathways included an estimate for DDGS co - product production which we similarl y applied to the advanced butanol production process. Since DDGS impact the agricultural markets, production of DDGs was already included as part of the FASOM and FAPRI modeling already described in the feedstock production section, above. Thus no

68 additional co - product credits for the DDGS are applied for the fuel production stage of the anal ys is. The advanced butanol production process analyzed here also results i n excess electricit y production. As per the pathway description the process produces excess electricit y of at least 40% of the purchased natural gas energy of the facility . The onsite emissions of the electricity production are accounted for in the facility natural gas and biogas use. The co - product credit of the excess electricit y is accounted for b y assuming the electricit y offsets average grid electricity production an d results in associated emission reductions.

69 pathway corn feedstock. The fuel t ype, butanol, and hence the fuel distribution for butanol, was already conside red as part of the RFS2 final rule. Therefore, the existing feedstock and fuel distribution lifecycle GHG impacts for corn butanol were applied to the advanced butanol pathway analy sis. Use of the fuel

– the advanced butanol pathway produces a fuel that was analyzed as part of the RFS2 final rule. Thus, the fuel combustion emissions calculated as part of the RFS2 final rule for butanol were applied to our anal ys is of the advanced butanol pathway . The advanced butanol fuel was then compared to baseli ne petroleum gasoline, using the same value for baseline gasoline as in the RFS2 final rule anal ys is. The results of the anal ys is indicate that the advance butanol pathway would result in a GHG emissions reduction of 51.3% compared to the gasoline fuel it would replace. Based on our LCA analysis, we are proposing to add a new pathway to Table 1 to section 80.1426 that includes butanol from corn starch using the butanol process described here as an advanced biofuel (D - 5 RINs). EPA invites comments on the assumptions used in this analy sis. Table V.F. - 2 below breaks down by stage the lifecycle GHG emissions for the RFS2 corn butanol pathway , the advanced butanol pathway and the 2005 gasoline baseline.

2. Butanol, Biobutanol, and Volatility Considerations Butanol is a flammable colorless liquid that is used as a fuel and as an industrial solvent. Butanol is composed of the chemical elements hydrogen, oxygen, and carbon. Itcan be made from petroleum or renewable biomass, such as corn, grasses, agricultural waste and other renewable sources. It can be used in internal combustion engines as an additive to gasoline and is currentl y registered under the Fuel and Fuel Additives Registration sy stem (FFARs) for use at up to 12 volume percent. A higher blend leve l would require a new FFAR S registration that would include meeting Tier 1 and Tier 2 health effects testing requirements. Biobutanol is the common name for butanol made from renewable sources. There has been an increased interest in the use of biobutanol as a direct result of the requirements for increased use of renewable fuel volumes, adopted in EI SA 2007. These provisions require an increase in the use of renewable fuels, with 36 billion gallons of renewable*** E.O. 12866 Review

72 fuel to be used in the U.S. by 2022. Parties required to meet these standards are interested in cost effective and practical way s to satisfy the standards and meet the performance needs of the vehicles and engines. Biobutanol is one attractive option because of its higher energy densit y, lower blending vapor pressure, and lower heat of vaporization in comparison to ethanol, as well as the fact that it can be distributed as a gasoline blend throughout the fungible gasoline distribution sy stem. The Clean Air Act ( section 211(h)(4)) requires EPA to adopt regulations limiting the volatility of gasoline during the summer months, when ozone is of most concern, including a one pound per square inch (psi) Reid Vapor Pressure (RVP) increase in the volatility limit for blends of gasoline containing 9 - 10% ethanol (E10). This allowance for a 1 psi increase in allowable volatility

is commonly

called the 1 psi waiver . EPA’s regulations at 40 CFR 80.27 adopt RVP standards that appl y to the gasoline at all points in the distribution sy stem, including the retail outlet. Under the provisions for the 1 psi waiver, blends of gasoline that contain from 9 volume percent to 10 volume percent ethanol are allowed to have volatility 1 psi higher than otherwise would be allowed (40 CFR 80.27(d)(2)). The chemical characteristics of ethanol are such that blends of gasoline with less than 9 volume percent to 10 volume percent ethanol would still have a significant increase in volatility . Thus the restriction on the 1 psi waiver to blends that have 9 volume percent t o 10 volume percent ethanol has the effect of prohibiting the blending of E10 with other gasoline/renewable fuel blends at an y point in the gasoline distribution system (wholesale or retail) in conventional gasoline areas during the summer control season. Blends of E10 gasoline and gasoline that is not*** E.O. 12866 Review

73 E10 would have less than 9 volume percent or greater than 10 volume percent ethanol, would have a resulting increase in volatility compared to E0, but would not have the 1 psi waiver to allow for such an increase. This in crease would lead to an RVP above the allowable limit, unless a sub - RVP gasoline blendstock was used. The practical effect is a prohibition on commingling of E10 and gasoline blends other than E10. Under the current regulations, EPA ap plies the RVP standard to the commingled mixture as a whole, not to the components of the commingled mixture. Once the ethanol and non - ethanol blends are mixed, the commingled mixture is treated as the gasoline that is tested and compared to the RVP stand ard. A single RVP value is determined by testing the volatility

of the commingled mixture, and this is compared to the standard. If the mixture has from 9 volume percent to 10 volume percent ethanol, then the 1 psi waiver applies to the mixture. If the mixture has a different percentage of ethanol, whether lower or higher, then the 1 psi waiver does not apply to the mixture. This avoids a situation where there is an overall increase in volatility because of the commingling of E10 and gasoline that is not E10. As discussed below, the chemical characteristics of ethanol and the nonlinear nature of the volatility increase associated with varying volumes of ethanol, mean that mixing E10 gasoline with gasoline that is not E10 ty picall y results in a n et overall increase in emissions

– the mixture has a higher volatility and emissions than the separate gasolines had on average before they were mixed.*** E.O. 12866 Review

74 Several parties have identified this as an obstacle that currently inhibits the opportunity for biobutanol to enter the commercial market. The primary issue is application of the RVP regulations at the final point of fuel dispensing, when the biobutanol (Bu) and the ethanol blends would be mixed, that is in a storage tank at the retail station. Whe n a butanol product that complies with the RVP standards prior to commingling (e.g. a compl yi ng B u 12 blend) is commingled with a compliant E10 in underground storage tanks at fuel dispensing facilities, the resulting mix generall y would exceed the ap plicable RVP standard as EPA’s RVP regulations currentl y appl y the standard. Certain fuels, including renewable biofuels such as butanol, however, do not have a net negative impact on RVP when blended with E10 at wholesale or retail. That is, the RVP and related emissions of the commingled blend of butanol and ethanol is no higher than the average RVP if the fuels had never been commingled. Thus, in these kinds of circumstances it may

be appropriate to adopt a modified approach to applyingthe RVP standard to permit the commingling of complying E10 blends with complying butanol blends at wholesale and retail, as there is no overall degradation of RVP and the air qualit y impacts compared to what would occur if they were not blended. Today , the agency

is providing some additional background on this issue and requesting information for use in deciding whether EPA can and should modify its RVP regulations as discussed below. Specifically , we are inviting comment on the ability of regulated parties to comply with the existing regulations by segregating biobutanol blends from ethanol blends and whether there is a need to change the regulations. We are also seeking comment on an alternative approach to applying the RVP standards to a commingled mixture of E10 with biobutanol or other approved gasoline additives, where the additives have characteristics such*** E.O. 12866 Review

75 that there is no net adverse emissions effect from the commingling. We are inviting comments as to whether the RV P standards can and should be applied such that the commingled mixture of E10 and specified blends of gasoline additives such as biobutanol is treated as complying with the RVP standard as long as the components of that mixture complied with the RVP standard prior to the commingling. This approach would provide a limited modification to how the RVP standards are applied, and the modification would apply for onl y certain fuel mixtures

– those where the overall or net volatility of the commingled mixture is no higher than the weighted average of the original blends themselves, such that there is no adverse impact on emissions from the mixing compared to what would have occurred without such mixing. In order to assist parties in preparing comments, EPA is pro viding some additional background regarding the RVP program in the following paragraphs. Background and History

of Volatility

Regulations Reid Vapor Pressure (RVP) is the most common measure of gasoline volatility under ambient conditions. In 1989 , EPA began reducing gasoline volatility by limiting its RVP (54 FR 11868 , March 22, 1989)(40 C.F.R. section 80.27). Due to the presence of gasoline in certain markets mixed with about 10 volume percent ethanol (known as gasohol at the time), and because blending an alcohol into gasoline increases the volatility of the final product, EPA provided an additional 1 psi allowance for such blends. In the absence of the 1 psi allowance, a special blend stock would have been required for such blends to comply wi th the RVP standards and such sub - RVP blendstocks did not exist at the time . EPA imposed the RVP standards at all points in the gasoline distribution sy stem , i.e., an ywhere gasoline is sold, supplied, offered for*** E.O. 12866 Review

76 sale or suppl y or transported , includ ing service stations, refinery shipping, tanks, importer shipping tanks, pipeline and bulk terminals and plants. (40 C.F.R. section 80.28)(1989). In 1990, the Agency

promulgated additional regulations that further lowered the RVP standards. (55 FR 23658, June 11, 1990). EPA continued to provide both the 1.0 psi allowance to fuel blends containing about 10 volume percent ethanol , (40 C.F.R. section 80.27)(1990), and the requirement that RVP standards applied at all points in the distribution sy stem. Congress largel y codified the approach taken in EPA’s RVP regulations b y adding a new section 211(h) in the 1990 CAA amendments. Section 211(h)(1) requires EPA to set the maximum RVP standard during the high ozone season as 9.0 psi. EPA wa s to “promulgate regulations making it unlawful for an y person during the high ozone season to sell, offer for sale, dispense, supply , offer for supply , transport, or introduce into commerce gasoline with a Reid V apor Pressure in excess of 9.0 pounds per square inch (ps i).” Lower RVP standards could be set for ozone nonattainment areas. S ee Clean Air Act section 211(h)(1). Section 211(h)(2) addresses the RVP standard that appl y in attainment areas, and sets the standard at 9.0 psi for attainment areas with authority f or EPA to set a more stringent RVP level under certain circumstances. In s ection 211(h)(2) , Congress allowed a 1 - psi waiver for E10 gasoline , stating: “For fuel blends containing gasoline and 10 percent denatured anh ydrous ethanol, the Reid vapor pressur e limitation under this subsection shall be one pound per square inch (psi) greater than the applicable Reid vapor pressure limitations established under paragraph (1).” Additionally , Congress enacted a conditional defense against liability for violations of the RVP level allowed under the 1 psi waiver b y stating that “[p]rovided; however, that a distributor, blender, marketer, reseller, carrier, retailer, or wholesale purchaser - consumer shall be deemed to be in full*** E.O. 12866 Review

77 compliance with the provisions of this s ubsection and the regulations promulgated there under if it can demonstrate that

– (A) the gasoline portion of the blend complies with the Reid vapor pressure limitations promulgated pursuant to this subsection; (B) the ethanol portion of the blend does no t exceed its waiver condition under subsection (f)(4) of this section; and (C) no additional alcohol or other additive has been added to increase the Reid Vapor Pressure of the ethanol portion of this blend.” Section 211(h)(4). In a 1991 rulemaking, EPA modified the RVP regulations to conform to the 1990 amendments ( 56 FR 64704 , December 12, 1991). These regulations addressed the RVP standards in attainment areas, required the use of denatured anh ydrous ethanol as a specific condition for the 1 - psi w aiver for fuel blends containing gasoline and from 9 volume percent to 10 volume percent ethanol, and included a new defense against liability for violations of the RVP standards for such fuel blends. We made no changes to the requirement that the RVP standards applied at all points in the distribution sy stem. What Modification is EPA Considering to the Application of the RVP Standards to Certain Fuel Blends? Gasoline and ethanol are mixed or blended after the refining process. The practice of blending ethanol with gasoline increases the RVP of the resulting blend by approximately 1.0 psi. It is a non - linear relationship , most of the volatility increase occurs after just a few percent of ethanol have been added, with the volatility increasing m ore slowl y as the gasoline ethanol blend increases to 10 volume percent . Above 10 volume percent the volatility generally does not*** E.O. 12866 Review

78 increase an y more, and at even higher levels of ethanol the volatility starts to decrease again. As explained above, sectio n 211(h)(4) provides a 1 - psi waiver for fuel blends containing gasoline from 9 volume percent to 10 volume percent ethanol. The absence of such a waiver would have required the creation of a production and distribution network for sub - 9.0 psi RVP gasoline , to offset the increase in volatility associated with blending ethanol into the gasoline. At the time the costs of producing and distributing an additional grade of this ty pe of fuel , especiall y in consideration of the low volumes of fuel being blended with ethanol at the time , would have likely been prohibitive and resulted in the termination of the availability of ethanol in the marketplace. Thus, the 1 - psi waiver facilitated the participation of ethanol in the transportation fuel industry

while also limiting gasoline volatility resulting from ethanol blending. But the RVP levels of gasoline actually used by consumers are dependent on the mixture of alcohol blends and gasoline that are commingling in either vehicle or storage tanks. Depending on th e mixture, the resulting RVP level could be significantly higher than the average volatility of the fuels prior to the commingling. This is because the volatility increase when ethanol is added to gasoline is non - linear, with a large increase with the fir st few percent and then slowly

tapering off as the concentration increases (see Illustration V.F. - 4 ). In other words, mixing E10 and EO gasoline results in a net increase in the volatility of the gasoline mixture, compared to the average volatility that w ould occur absent such mixing. For example, 2000 gallons of 10 psi E10 added to a service station tank with 8000 gallons of 9.0 psi E0 would result in 10 , 000 gallons of fuel with a volatility of approximately 10 psi. However if the fuels had not been mix ed, the average volatility of the 10000 gallons would have been 9.2 psi. The emissions associated with the commingled mixture (10000 gallons at 10 psi) would be significantly higher*** E.O. 12866 Review

– Draft

79 than the emissions associated with the two separate blends of 2000 gallon s at 10 psi and 8000 gallons at 9 psi. The commingling thus results in an adverse environmental impact compared to what would occur absent the commingling. EPA’s current RVP regulations address this adverse emissions impact by

applyingthe RVP standard t o the commingled mixture as a single fuel. In this case the commingled mixture has an RVP of 10 psi. The 1 psi waiver does not apply as the mixture is now 2% ethanol, not from 9 volume percent to 10 volume percent ethanol. The commingled mixture thus wo uld not comply with the 9.0 psi RVP standard, effectivel y prohibiting such commingling. As discussed earlier, the EPAct 2005 and EISA2007 mandated increased volumes of renewable fuel for use in gasoline. This has resulted in the increased use of ethanol . E10 is now present in nearly

all gasoline sold in the country . Recently , EPA granted a waiver from the substantially

similar requirements under section 211(f) (4) for the use of E15 blends in MY2001 and newer light - dut y vehicles ( See 75 FR 68094 , Novemb er 4, 2010 and 76 FR 4662 , January 26, 2011). EPA interpreted section 211(h) as not extending the 1 psi waiver to such blends with ethanol levels above 10%. Several companies are also developing and planning on introducing biobutanol into commerce. The c haracteristics of butanol are such that it could be beneficial with respect to volatility

and vehicle evaporative emission performance. For example, 2000 gallons of 10 psi E10 added to a service station tank with 8000 gallons of 9.0 psi B u 12 would result in 10000 gallons of fuel with an RVP of 9.2 psi. The RVP of the commingled blend would be the same as the average of the separate blends if they had never been commingled. There is no adverse emissions impact from the commingling of the E10 and B u 12 blends. However the 1 - psi waiver would not be applicable because the resulting blend no longer contains from 9 volume*** E.O. 12866 Review

80 percent to 10 volume percent ethanol. The RVP level for the resulting blend would also be higher than the maximum RVP stand ard of 9.0 psi, making the commingled blend noncompl yi ng with the RVP standard. However the available data indicates that commingling of biobutanol blends with ethanol blends would not result in any net increase in gasoline volatility . This is because bi obutanol blends and gasoline containing from 9 volume percent to 10 volume percent ethanol blend linearl y from a volatility perspective, resulting in no net increase in volatility compared to what would occur without the blending. This means that there would be no net degradation in environmental performance , as indicated in Illustration V.F. - 4, below. We are inviting comment on an alternative approach to applying the RVP standard to the gasoline that results from commingling of E10 and certain other products like biobutanol. We are inviting comment as to whether the RVP standards could be applied to the commingled blend such that the commingled blend would be considered in compliance as long as the separate components of the commingled product were in compliance with the RVP standards prior to commingling. In effect the RVP standard would be applied to the commingled mixture by treating it as if it still contained two separate products, with each product required to compl y with the RVP standard separat el y. This approach would be somewhat artificial but would allow for the commingling of specified blends of fuels, such as biobutanol, with E10 where the resulting commingled mixture does not result in a net increase in average RVP and associated emission s. This would provide more flexibility in achieving the RFS standards while avoiding adverse environmental impacts. This approach would provide a limited modification to the RVP provisions for only

certain fuel blends. EPA invites comment on whether it would have the*** E.O. 12866 Review

– Draft

– Do Not Cite, Quote, or Release During Review***

81 authority under § 211(h) to adopt such an approach, and if so whether it would be appropriate to do so and under what conditions. Specificall y, we would consider imposing the following conditions on such fuel blends: (1) Each separate c omponent must individually meet the applicable RVP standards (e.g., 10 psi for E10 and 9 psi for other blends). (2) The resulting commingled mixture would have to have an RVP that is no higher than the weighted average of the products or components consid ered separatel y. This could occur with blends that blend linearl y with respect to RVP (e.g., butanol ). (3) The burden would be on the retailer to show that these conditions had been satisfied. If a comm ingled product had volatility above the allowable standard, and did not have from 9 volume percent to 10 volume percent ethanol, then the fuel would be considered noncompl yi ng unless the regulated party demonstrated that it met the limited conditions discussed here. The retailer would have to demonstrate that the conditions were met for application of this modified method of determining compliance. This would call for at least retaining records of the products received (with all required regulatory statements and indications required) and volumes of the products received in order to demonstrate a calculation to verify compliance with the RVP standard .*** E.O. 12866 Review

82 (4) In situations where the RVP of retail tank samples exceed 9.0/7.8 psi, for defense purposes the retailer would need to test the sample for the concentration of ethanol, butanol, and any other applicable ox ygenate in addi tion to the RVP level in order to allow for the calculation in (3 ). The resulting blend ratio would need to meet or demonstrate better performance reductions of such ratio on a linear scale as established through regulation. Under this approach, we bel ieve there would be no adverse environmental effects because such mixtures would result in no net increase in volatility . We also believe this would enable us to give effect to the RFS provisions that call for increased use of renewable fuels, and also be consistent with our rational for the treatment of gasohol at the time we promulgated the RVP standards.*** E.O. 12866 Review

84 F . Amendments to Various RFS2 Compliance Related Provisions

We are proposing a number of changes to the RFS2 regulations . 1. Proposed Changes to Definitions “Responsible Corporate Officer” The existing RFS2 regulations at sections 80.14 16, 80.1451 and 80.1454, and EPA guidance and instructions regarding registration and reporting, frequentl y refer to the responsibilities of the “ owner or a responsible corporate officer.” However, th e term “responsible corporate officer” is not currentl y defined in the RFS2 regulation s . We propose that, for purposes of the RFS2 program, a “ responsible corporate officer” (RCO) means a corporate officer who has the authority and is assigned responsibility to provide information to EPA on behalf of a company . A compan y ma y name only one RCO, and the RCO may not delegate his/her responsibility to an y other person. However, the RCO may delegate the ability to submit information to EPA to one or more employee s of the company or to one or more agent s . The RCO remains responsible for the information submitted to EPA by an y employee or agent. Adding a definition of RCO will codify existing practice s and will assist regulated parties in understanding roles under the RFS2 regulation.
“Small Refinery”*** E.O. 12866 Review

– Draft

– Do Not Cite, Quote, or Release During Review***

85 Se ction 211(o)(9)(A) of the Clean Air Act provides an exemption from RFS requirements through 2010 for “small refineries,” defined as refineries having an average aggregate dail y crude oil throughput for a calendar ye ar that does not exceed 75, 000 barrel s. Italso provides for possible extensions of this exemption, through individual petitions to EPA. CAA 211(o)(9)(B). In EPA’s March 26, 2010 regulations implementing the EI SA amendments we specified in the regulatory

definition of “small refi nery” that the 75,000 bpd threshold determination should be calculated based on information from cale n dar year 2006 . At the beginning of the program, having a single ye ar in which to make this determination , simplified the calculations , and helped to ensure that all refineries were treated similarly . However, we no longer believe that it is appropriate that refineries satisfying the 75,000 bpd threshold in 2006 should be eligible for extensions to their small refinery RFS exemption if they no longer meet the 75,000 bpd threshold . Allowing such facilities to qualify for an exemption extension, while not allowing similarly sized facilities that have not grown since 2006 to qualify for an exemption , does not appear fair, n or does it further the objectives of the statute to target relief to only trul y small facilities. Therefore, we propose modifying the definition of small refinery so that the crude throughput threshold of 75,000 bpd must apply in 2006 and in all subsequent y ears . We also propose specifying in section 80.1441(e)(2)(iii) that in order to qualify for an extension of its small refinery

exemption, a refinery

must meet the definition of “small refinery” in section 80.1401 for all full calendar years between 2006 and the date of submission of the petition for an extension of the exemption.*** E.O. 12866 Review

86 We proposed that that these changes would not a ffect an y existing exemption extensions under CAA 211(o)(9)(B) ; rather, they would apply

at such time as any

approved exemption extensi on expires and the refinery at issue seeks a further exemption extension. No further extension would be permitted unless the revised crude oil throughput specifications were satisfied.

2 . Provisions for Small Blenders of Renewable Fuels The RFS2 regulations at section 80.14 40 allow renewable fuel blenders who handle and blend less than 125,000 gallons of renewable fuel per year, and who are not obligated parties or exporters, to delegate their RI N - related responsibilities to the party directly ups tream from them who supplied the renewable fuel for blending . EPA has received feedback from several parties to the effect that the 125,000 threshold is too low , and is a lower threshold than what industry considers “small .” EPA seeks input on what a mor e appropriate gallon threshold should be. EPA seeks comment on the regulated community ’s experience with the existing gallon threshold associated with the provisions. EPA may adjust the gallon threshold in the final rule based on further consideration of this issue and evaluation of comments received.
3 . Proposed Changes to S ection 80.1450

– Registration Requirements*** E.O. 12866 Review

– Draft

– Do Not Cite, Quote, or Release During Review***

87 We propose to add a new paragraph ( h ) to section 80.1450 that will des cribe the circumstances under which EPA may cancel a company registration. EPA proposes to initiate a process to cancel a company registration if the company has reported no activity

in the EPA Moderated Transaction Sy stem (EMTS) under section 80.1452 for one year. EPA also proposes to initiate a process to cancel a compan y registration if a part y fails to comply with an y registration requirement of section 80.1450, if the party fails to submit any

required compliance report under section 80.1451, if the part y fails to meet the requirements related to the EPA Moderated Transaction Sy stem (EMTS) under section 80.1452, or if the party fails to meet the requirements related to attest engagements under section 80.1454. If an y required report, including the attest engagement, is thirty (30) or more day s overdue, EPA would provide written notice to the owner or responsible corporate officer (RCO) that it intends to cancel the compan y ’s registration and w ould allow the company fourteen (14) day s from the date of the letter ’s issuance to respond. If there is no satisfactory response received, then EPA would cancel the registration. Re - registration would be possible following the standard registration procedures. 4 . Proposed Changes to Section 80.1452

– EPA Moderated Transaction Sy stem ( EMTS) Requirement s – Alternative Reporting Method for Sell and Bu y Transactions for Assigned RI Ns Reporting and product transfer document (PTD) requirements, found in sections 80.1452 and 80.1453, respectively , currentl y state that the reportable event for a RIN purchase or sale occurs on the date of transfer. Sellers must report the sale of RINs within five (5) business day s*** E.O. 12866 Review

88 of the reportable event via the EPA Moderated Transaction Sy stem (EMTS). Bu ye rs must report the purchase of RINs within ten (10) business days of the reportable event via EMTS. The date of transfer is the date on which title of RI Ns is transferred from the seller to the buy er. Some buyers and sellers of assigned RINs have expressed concerns with these requirements stating they have difficulty

determining the date of transfer since title of the renewable fuel is not transferred until the fuel phy sicall y reaches the buyer. Some transactions, for example those by rail or barge, may

take several weeks, and their current accounting sy stems do not include a means for capturing the buyer’s rece ipt date. EPA understands this concern, but also recognizes that some regulated parties have modified their accounting s ys tems to address the current reporting and PTD requirements in RFS2. We also believe that for parties separating, retiring, and sel ling or buying separated RINs, the current reporting and PTD requirements are effective and should remain unchanged. Therefore, at this time EPA is not proposing to replac e existing requirements, but is instead proposing an additional, alternative method for reporting sell and bu y transactions involving assigned RINs only . The proposed alternative method for sell and bu y transactions of assigned RINs would redefine the reportable event for both the seller and the buyer, introduce a unique identifier that the seller must provide to the buy er, and require the buy er to report the date of transfer. Bu ye rs and sellers would need to agree on which method they w ould be using to report transfers of assigned RINs; either the current method or the alternative method. EPA believes that this alternative w ould provide the regulated community with the flexibility

to address their reporting*** E.O. 12866 Review

89 concerns and also provide EPA with the data necessary to effectivel y administer and enforce transactions of assigned RI Ns. EPA w elcomes comment on this proposed alternative method for reporting assigned RIN buy and sell transactions. We propose that sellers of assigned RINs under the alternative method be required to do the following:

 Within five (5) business day s of shipping renewable fuel with assigned RINs, report a sell transaction, using the alternative method, via EMTS;  In clude in the EMTS sell transaction report other required information per section 80.1452; and  Provide a PTD to the assigned RIN bu yer with a unique identifier, also reported via EMTS, in addition to the information in section 80.1453. The date of transfer is not required for the alternative method. We propose that buyers of assigned RINs under the alternative method be required to do the following:

 Within five (5) business day s of receiving a shipment of renewable fuel with assigned RI Ns, report a bu y transaction, indicating use of the alternative method, via EMTS;  In clude in the EMTS bu y transaction report other required information per section 80.1452 ;*** E.O. 12866 Review

90  In clude in the EMTS bu y transaction report the unique identifier provide d by the seller; and  In clude in the EMTS bu y transaction report the date the renewable fuel was received, i.e. the date of transfer. If this proposed alternative method is finalized , the EMTS w ould be modified to accept such transactions. EPA w ould provide additional instruction and guidance at the time of the new EMTS version release. EPA invites comment on all aspects of this proposal. 5 . Proposed Changes to Section 80.1463

– Confirm that Each Day an Invalid RIN remains in the Market place is a Separate Day

of Violation. Preventing the generation and use of invalid RINs and encouraging rapid retirement and replacement of invalid RINs is crucial to the integrity of the RFS2 program. The RFS regulations include various provisions related to prohibited acts and liability for violations. Section 80.1460(a) sets forth the prohibited acts for the renewable fuels program. Section 80.1460(b)(2) prohibits parties from creating or transferring invalid RINs. Section 80.1461(a) states that the person who violates a prohibited act is liable for the violation of that prohibition. Section 80.1461(b) provides the liability provisions for failure to meet other provisions of the regulati ons. The penalty

provisions of the regulations at section 80.1463(a) state that any person who is liable for a violation under section 80.1461 is subject to a civil penalty as specified in sections 205 and 211(d) of the Clean Air Act (CAA), for every day of each such violation and*** E.O. 12866 Review

91 the amount of economic benefit or savings resulting from each violation. Section 80.1463(c) provides that “an y person...is liable for a separate day of violation for each day such a requirement remains unfulfilled.” EPA interpret s the se statutory and regulatory penalty

provisions to give the Agency the authority to seek penalt ies against parties generating, transferring or causing another person to generate or transfer invalid RI N s for each day subsequent to the part y’s action that an invalid RI N is available for sale or use by a part y subject to an obligation under the RFS2 program to acquire and retire RINs. For example, for a RIN generator, this time period ty picall y runs from the date of inv alid RI

N generation until either corrective action is taken by the RIN generator to remove the invalid RIN from the marketplace or a party uses the RIN to satisfy

an RVO or other requirement to retire RINs (such as would appl y under today ’s proposal to exp orters of renewable fuel or parties using fuel produced as renewable fuel for a use other than as transportation fuel, heating oil or jet fuel ). This is consistent with the CAA approach of assessing penalties for every day of a violation , consistent with EPA’s historic approach under the fuels regulations ( See Section 80.615), and will encourage renewable fuel producers that generate invalid RINs to promptly take corrective action. We are proposing to amend section 80.1463 to more explicitly incorporate EPA’s interpretation of these penalty provisions into the regulations. The amendments w ould state that any person liable for a violation of section 80.1460(b) for creating or transferring an invalid RIN, or for causing another person to create or transfe r and invalid RI N, is subject to a separate day of violation for each day

that the invalid RI

N remains available for use for compliance purposes, and EPA has the authority to seek the maximum statutory penalty for each day of violation . EPA*** E.O. 12866 Review

92 will apply

the statutory

factors in sections 211(c) and 205(b) of the CAA to evaluate the appropriate penalties for each violation on a case by case basis. 6 . Proposed Changes to Section 80.1466

– Require Foreign Ethanol Producers, Importers and Foreign Renewable Fuel Producers that Sell to Importers to be Subject to U.S. Jurisdiction and Post a Bond. The current regulations include requirements that foreign renewable fuel producers that generate RINs agree to be subject to a number of additional requirements at sec tion § 80.1466, including, but not limited to, designation, foreign producer certification, product transfer document, load port independent testing and producer identification, submission to U.S. jurisdiction and posting of a bond. We are proposing to re quire the same requirements for foreign renewable fuel producers , and foreign ethanol producers that produce biofuel for which importers ultimately

generate RINs, and for importers of renewable fuel. Inorder to evaluate whether a fuel qualifies as RIN generating renewable fuel (including determining the proper renewable fuel category and RI N t ype for the imported fuel), EPA must be able to evaluate the feedstocks and processes used to produce the renewable components of the fuel. This is a particular c hallenge for fuel produced at foreign facilities; unlike our other fuels programs, EPA cannot determine whether a particular shipment of renewable fuel is eligible to generate RINs under the RFS program by testing the fuel itself. Furthermore, significant opportunit y for fraud and non - compliance with the regulations exists where EPA is not able to ensure that RINs entering the U.S. are valid, and where enforcement of the regulations may

be hampered due to a facility ’s foreign location. We believe that the same safeguards that appl y to foreign RIN generating renewable fuel producers should apply to other*** E.O. 12866 Review

93 foreign producers whose product is used by importers to generate RINs , and to those importers themselves . Accordingl y, we propose that foreign renewable f uel producers and foreign ethanol producers who do not themselves generate RINs for their product, and importers of renewable fuel, be required to comply with the safeguards of section 80.1466 . Given the challenges associated with EPA’s ability to determi ne whether a fuel qualifies as RIN generating renewable fuel, and the potential for fraud, we believe these additional safeguards are necessary for all foreign produced renewable fuel, regardless of who generates the RINs. However, we seek comment on the reasonability of expanding these additional requirements onto foreign renewable fuel producers , and foreign ethanol producers that produce biofuel for which importers ultimately

generate RINs, and for importers of renewable fuel. We further propose to ame nd section 80.1426(a)(4) to prohibit importers from generating RINs for renewable fuel imported from a foreign renewable fuel producer or foreign ethanol producer , unless and until the foreign renewable fuel producer or foreign ethanol producer has satisfied all requirements of section 80.1466.

94 of: (1) one cent times the largest volume of renewable fuel produced b y the foreign producer and exported to the United States, in gallons, during a single calendar y ear among the five preceding calendar years, or the largest volume of renewable fuel that the foreign producers expects to export to the Unites States during an y calendar ye ar identified in the Production Outl ook Report required b y section 80.1449 , or (2) the sum of the following calculation for each RIN typ e: 0. 25 times the largest volume of renewable fuel produced by the fo reign producer and exported to the United States, in gallons, during a single calendar y ear among the five preceding calendar years, or the largest volume of renewable fuel that the foreign producers expects to export to the Unites States during an y calend ar year identified in the Production Outl ook Report required b y section 80.1449 , times a “ RI

N multiplier D code ” established by EPA in the regulations. The proposed “ RI

N multiplier D codes ” vary from $.02 for D code 6 to $1.30 for D code 4. When the original renewable fuels standard regulation s (RFS1) w ere written, an RFS1 RI N was worth pennies. With the implementation of RFS2, the price of some RINs has increased significantl y, in part because of the demand for certain categories of fuel such as bio mass - based diesel. In order to keep up with these market conditions, the bond amount needs to be increased; a penny per gallon of fuel may

no longer be a fair valuation of a foreign renewable fuel producer’s potential penalty

for RFS violations. Bonds are used to satisfy an y judicial judgment that results from an administrative or judicial enforcement action for conduct in violation of this subpart. Therefore, we propose to amend section 80.1466(h)(1) to include the calculation described above, that reflec ts current market valuation for different ty pes of RINs. We seek comment on whether the proposed bond calculation procedures are appropriate, and in particular whether they are sufficientl y large to cover potential liability . .*** E.O. 12866 Review

95 EPA also proposes to amend paragraph (h) of section 80.1466 to be consistent with paragraph (j)(4), which prohibits generating RINs in excess of the number for which the bond requirements have been satisfied. Paragraph (h) regulates the size of the bond a foreign renewable fue l producer must post in order to generate RINs. This formula takes into account the volume of renewable fuel a foreign renewable fuel producer has exported or intends to export to the United States. Section 80.1466(h) states, in part: “If the volume of renewable fuel exported to the United States increases above the largest volume identified in the Production Outlook Report during any calendar year, the foreign producer shall increase the bond to cover the shortfall within 90 days.” This conflicts with the stricter language in paragraph (j)(4) of the same section, which prohibits a foreign producer of renewable fuel from generating RINs in excess of the number for which the bond requirements of section 80.1466 have been satisfied. EPA interprets the stri cter provision at section 80.1466(j)(4) to be controlling, and we propose to change the language in section 80.1466(h ) accordingl y .
8 . Proposed Changes to Facility ’s Baseline Volume to allow “Nameplate Capacity” for Facilities not Claiming Exemption from the 20% GHG Reduction Threshold As a requirement of registration under the RFS2 program, each renewable fuel producer and foreign ethanol producer must establish and provide documents to support its facility’s baseline volume as defined in section 80.1401 . This is either the permitted c apacity or, if permitted capacity

cannot be determined, the actual peak capacity of a specific renewable fuel*** E.O. 12866 Review

96 production facilit y on a calendar ye ar basis. After the promulgation of the March 26, 2010 RFS2 rule, we have received many requests from companie s to allow them to use their nameplate or “design” capacit y to establish their facility’s baseline volume due to either the facility being exempt from obtaining a permit, and thus not able to determine their permitted capacity , or the facility not starting operations, or not being operational for a full calendar year to produce actual production records to establish actual peak capacities. Because the regulations currentl y only allow a facility ’s baseline volume to be established by a limit stated in a per

mit or actual production records for at least one calendar ye ar, facilities that had neither a permit or sufficient production records had difficultly registering under the RFS2 program. To allow facilities that fall under this predication to register und er the RFS2 program, we are proposing in this rulemaking to allow a facility to use its “nameplate capacity” to establish its facility ’s baseline volume for the purposes of registration, onl y if 1) the facility does not have a permit or there is no limit s tated in the permit to establish their permitted capacity, and 2) has not started operations or do es not have at least one calendar year of production records, and 3) do es not claim exemption from the 20 percent GHG threshold under § 80. 1403. Due to the c omplexity of the exemption provision provided under § 80. 1403, and the added flexibility that facilities claiming this exemption are allotted under the program, we are not proposing to extend this option to facilities claiming an exemption under § 80.1403 . Additionally , by this stage in the RFS2 program, the facilities that would qualify for registration under § 80. 1403 would be very few, if an y. This proposal would revise the definition of baseline volume to include “nameplate capacity , ” add a new definition for “nameplate capacity” to § 80. 1401, and include conforming amendments to the registration requirements of §80.1450.*** E.O. 12866 Review

97 G . Minor Corrections to RFS2 Provision s We are proposing a number of corrections to address minor definit i on al issues that have been identified as we have been implementing the RFS2 program. Renewable Biomass We propose to amend the definition of “renewable biomass” in section 80.1401 to make clear that biomass obtained in the vicinity of buildings means biomass obtained within 200 feet of the buildings. The preamble for the March 26, 2010 RFS2 final rule cites the distance of 200 feet (See 75 FR 14696), but EPA did not include a reference to this value in the regulations . We believe doing so would provide additional clarity t o the regulations. English Language Translations We propose to add a new paragraph ( i ) to section 80.1450 to state that any registration materials sub mitted to EPA must be in English or accompanied b y an English language translation. Similarly , we propose to add a new paragraph (h) to section 80.1451 that will state that any reports submitted to EPA must be in English or accompanied by an English language translation and add a new paragraph (q) to section 80.1454 that will state that an y records submitted to EPA must be in English or accompanied by an English language translation.

pographical Errors We propose to correct various ty pographical errors in section 80.1466. Specificall y, we propose to amend paragraph (o) to correct a typographical error in the last sentence of the affirmation statement, b y changing the citation from §80.1465 to §80.1466. We also propose to amend paragraph (d)(3)(ii) to correct a t ypographical error. The current regulation cites section 80.65(e)(2)(iii), which does not exist.

B. Proposed Changes to Section 80.1502

– E15 Survey We are proposing two changes to the survey requirements found at section 80.1502. First, we propose to clarify that E15 survey s need to sample for Reid vapor pressure (RVP) only during the high ozone season as defined in section 80.27(a)(2)(ii) or during an y time RVP standards appl y in an y state implementation plan approved or promulgated under the Clean Air Act. EPA did not intend to require RVP sampling and testing during the rest of the year, when RVP standards do not apply . Second, we propose to change when the results of surv ey s that detect potential noncompliance must be reported to the Agency . As originall y drafted, the regulations require the independent survey

association conducting a survey to notify EPA of potentially

noncompliant samples within 24 hours of the laborato ry receiving this sample( See 76 FR at 44423 , July 25, 2011) . EPA has since learned that more time may be needed for reporting of noncompliant samples since it may

take several day s for anal ys is of the sample to be complete d . We are therefore requiring th at noncompliant samples be reported to EPA within 24 hours of being anal yz ed.*** E.O. 12866 Review

100 C. Proposed Changes to Section 80.1503

– Product Transfer Documents EPA is proposing certain minor changes to the product transfer document (PTD) requirements found at sect ion 80.1503. Specifically , we are proposing to allow the use of product codes for conventional blendstock/gasoline upstream of an ethanol blending facility , since historically , the codes have been allowed to be used for conventional blendstock/gasoline upstream of an ethanol blending facility in other fuels programs. This was an omission from the original regulation. We are also seeking comment on potential way s of streamlining the PTD language required at section 80.1503.

D. Proposed Changes to Section 80.1504 - Prohibited Acts EPA is slightly

rewording section 80.1504(g) to state that blending E10 that has taken a dvantage of the statutory 1.0 psi RVP waiver during the summertime RVP control period with a gasoline - ethanol fuel that cannot take advantage of the 1.0 psi RVP waiver (i.e. a fuel that contains more than 10.0 volume percent ethanol (e.g., E15) or less than 9 volume percent ethanol) would be a violation of the E15 MMR. As originall y written, the language does not clearl y describe the prohibited activity (see 76 FR 44435, 44436 , Jult 25, 2011 ).*** E.O. 12866 Review

101 E. Proposed Changes to Section 80.1500 -- Definitions On August 17, 2011, the National Petroleum Refiners Association, now called American Fuel and Petrochemical Manufacturers (AFPM), filed a petition for reconsideration with the Agency under CAA section 307(d)(7)(B) asking EPA to reconsider certain portions of the E15 MMR. A copy

of the petition has been placed in the docket. The petition fundamentally focuses on one issue - AFPM expressed concern that the Agency had defined E10 and E15 in the E15 MMR in a way

that would change how ethanol concentrations are determined for regulatory purposes. Today

we grant AFPM’s request for reconsideration of this issue as explained in their August 17, 2011 petition. As explained below, while EPA did not intend the definitions of E10 and E15 in the E15 MMR to have this ef fect, we are proposing changes to the regulations to avoid this perceived impact. On April 6, 1979, fuel containing 90% unleaded gasoline and 10% eth ylalcohol received a waiver under section 211(f)(4) b y operation of law (see 44 FR 20777, April 6, 1979 ). Later, EPA issued an interpretative ruling that stated the April 6, 1979 waiver covered gasoline - ethanol blends that contained up to 10 vol% ethanol content (see 47 FR 14596, April 5, 1982). Finally , in the context of regulations limiting the Reid vap or pressure (RVP) of gasoline, EPA has defined E10 as gasoline containing between 9 and 10 volume percent ethanol. Under the RVP regulations and the Clean Air Act, the RVP of E10 is allowed to be 1 pound per square inch (psi) higher than it is for gasolin e or gasoline - ethanol blends containing less than 9 and more than 10 vol% ethanol (often referred to as the “1.0 psi waiver”).*** E.O. 12866 Review

– Draft

– Do Not Cite, Quote, or Release During Review***

102 In the E15 MMR, EPA defined E10 as gasoline containing at least 9.0 and no more than 10.0 vol% ethanol and defined E15 as a gaso line - ethanol blend containing greater than 10.0 and no more than 15.0 vol% ethanol. EPA included those definitions in the E15 MMR so that fuels blended to contain more than 10.0 vol% ethanol were subject to the misfueling mitigation requirements for E15. After publication of the E15 MMR, stakeholders including AFPM expressed concern that by defining E10 as E10.0, the Agency may have effectivel y made the ethanol concentration limits specified in the E10 and the E15 waiver decisions and the RVP regulations more stringent, which in turn would impact whether a part y must comply with the E15 MMR requirements and whether a fuel qualifies for the RVP 1.0 psi waiver. In its petition, AFPM noted that under existing EPA regulations at 40 CFR 80.9, the results of compliance testing for the ethanol concentration in gasoline are “rounded down” when the results indicate that gasoline - ethanol fuel may contain slightly

more than 10 vol% ethanol. AFPM further stated that in view of this rounding procedure, fuel that co mpliance testing indicates has an ethanol concentration of between 10.0 and 10.4 should be considered E10. AFPM argued that the E15 MMR definition of E10 as containing no more than 10.0 vol% ethanol constituted a “substantive change” to the proposed E15 M MR that would also alter the implementation of other EPA fuels regulations without a required rulemaking. As part of the E15 MMR proposed rule, we identified prospective responsible parties for each misfueling mitigation measure, including requirements r elated to labeling E15 fuel dispensers, compliance survey s, and product transfer documents. We received a number of comments from man y affected stakeholders, including AFPM, that asked us to clarify which*** E.O. 12866 Review

103 party or parties would be responsible for each mis fueling mitigation measure and when each party or parties would be subject to those requirements. In the final E15 MMR, we added the significant digit to the definitions of E10 and E15 in order to provide a delineation between E10 and E15 and consequently the parties subject to one or more of the E15 misfueling mitigation measures. AFPM argued in their petition that by defining E10 as containing no more than 10.0 vol% ethanol, EPA effectivel y made a substantive change to the way test results used for determining compliance with fuel requirements are rounded. For example, for a gasoline - ethanol blend to be considered E10, it could no longer contain up to 10.4 vol % ethan ol; it could only contain up to 10.04 vol % ethanol. AFPM asserted that there is a tolerance for blending ethanol that allows blends containing up to 10.4 vol % ethanol to be considered E10. While we do not agree that there is a blending tolerance for ethanol, we agree that test results are rounded utilizing the procedures identified in section 80.9 when compared to applicable standards, in this case the ethanol concentrations specified in the E10 and the E15 waivers. The Agency

specifically

addressed th e issue of blending tolerances versus testing tolerances for gasoline - ethanol blends in the RFS2 NPRM. 47 At the time, some stakeholders had suggested that the implementation of a blending tolerance for the ethanol content of gasoline could be allowed to he lp obligated parties satisfy RFS requirements without the need for a CAA section 211(f)(4) waiver. In response, we argued that although the test methods used to measure ethanol concentration (ASTM D 5599 and ASTM D 4815) include some variability , ethanol is

104 different than other fuel properties and components that are controlled in other fuel programs. 48 Fuel properties such as RVP, and components such as sulfur and benzene, are natural characteristics of gasoline as a result of the chemical nature of crude oil and the refining process. Their levels or concentrations in gasoline are unknown until measured and are dependent upon the accuracy

of the test method. In contrast, ethanol is intentionally added in known amounts using equipment designed to ensure a specific concentration within a very narrow range. Parties that blend ethanol into gasoline normally have precise control over the final concentration. Therefore, a blending tolerance for ethanol would not be appropriate. D uring the comment period for the RFS2 NPRM, EPA received a number of comments from stakeholders that argued that the volume percentage of ethanol in gasoline is readily determined using very

accurate volumetric ratio blending facilities now in place at most blending terminals; therefo re, the Agency should not allow a blending tolerance. In the final RFS rule, we did not include a blending tolerance for ethanol blends. 49 We continue to believe that blending tolerances for ethanol are not appropriate, and the definitions of E10 and E15 in the E15 MMR are consistent with this view. The E10 waiver is for gasoline containing “up to” 10 vol% ethanol, not for gasoline containing “up to” 10.4 vol % ethanol, and the E15 partial waivers are for fuel designed to contain “greater than 10 vol% eth anol and not more than 15 vol% ethanol.” In the case of both waivers, the “10” and the “15” are exact numbers, not approximations, and they express how much ethanol can be lawfully added to fuel. Testing b y the Department of Energy utilized in making the E15 partial waiver decisions was blended as precisel y as possible to contain the relevant percentage of ethanol, not 48 See 74 FR 25018 (May 26, 2009). 49 See 75 FR 14762 - 14764 (March 26, 2010).*** E.O. 12866 Review

105 that percentage plus “0.49”. Testing for registration of E10 and E15 fuel and fuel additives under 40 CFR part 79 was also done with fuel s blended as precisel y as possible to contain the relevant percentage of ethanol. Similarly , EPA regulations provide that only fuel with an ethanol concentration of between 9 and 10 vol%, not more or less, may lawfull y use the statutory 1.0 psi RVP waiver . At the same time, we did not intend to change the definition of E10 in a way that impacts the rounding of test results for ethanol concentrations. 50 If a manufacturer blends in a way designed to result in a gasoline - ethanol fuel containing no more than 10.0 vol% ethanol, but compliance testing indicates a concentration of 10.4 vol%, we will still round down the test result in accordance with procedures in section 80.9. The purpose of the E15 MMR definitions state that if a manufacturer blends ethanol into gasoline in a way designed to result in a gasoline ethanol fuel containing greater than 10.0 vol% and no more than 15.0 vol% ethanol, it will be subject to applicable E15 MMR requirements. For example, bills of lading for an E10 fuel manufacturer that indicates the manufacturer has purchased and blended more ethanol than 10.0 vol% ethanol may

indicate that a fuel does not meet the definition of E10 for E15 MRR purposes. AFPM also argued that the E15 MMR definitions of E10 would alter the implementati on of other EPA fuels regulations without a required rulemaking, specifically the application of the 1.0 psi RVP waiver to E10. Since the Agency intended the E15 MMR definition of E10 to only apply for purposes of determining the applicability of E15 MMR requirements, the Agency does

106 not believe these definitions affect the implementation and enforcement of others fuels programs, including the applicability of the 1.0 psi RVP waiver. The introductory language to the definitions at 40 CFR part 80, subpart N clearly states that definitions in section 80.1500 are “[f]or purposes of this subpart only .” In order to clarify

that these definitions only apply in the context of the E15 MMR, EPA is proposing to add a new section 80.1509, which contains language th at clearl y states that when ethanol concentrations are measured for compliance testing purposes for 40 CFR, Part 80, Subpart N, the applicable ethanol concentration value will be rounded using the rounding procedures at section 80.9. EPA is also proposing new prohibit ed acts language in section 80.1504 that should make it clear that onl y those parties that (1) produce gasoline, blendstocks for ox ygenate blending (BOBs), or ethanol designed to be used in the manufacture of E15 as currentl y defined (i.e., E1 5.0); (2) that manufacture E15 to be introduced into commerce; or (3) that dispense E15 from a retail outlet. The Agency specificall y seeks comments on this proposed language.

VII. Proposed Amendments to the UL SD Diesel Sulfur Survey EPA is requesting comment concerning whether to amend a provision of the ultra - low sulfur diesel (ULSD) rule. The ULSD rule includes a provision that deems branded refiners liable for violations of the UL SD sulfur standard that are found at retail outlets displaying the r efiner’s brand (40 CFR §80.612). The regulations include defense provisions. One element of a*** E.O. 12866 Review

107 branded refiner’s defense to such violations is that it must have a periodic sampling and testing program at the retail level (40 CFR 80.613(b) and (d)). The r egulations also set forth an alternative sampling and testing defense element provision for branded refiners. This alternative defense element provision (40 CFR §80.613(e)) allows a branded refiner to meet the compan y - specific downstream periodic sampling and testing element of its defense by participating in funding a survey consortium that samples diesel fuel at retail outlets nationwide. This sampling and testing of fuel to determine compliance with the UL SD sulfur standard is carried out b y an independent survey association. EPA reviews and approves the annual survey

plan submitted by

the survey

association. The number of samples that are taken each ye ar is determined by a statistical formula that is based in part on the previous year’s compliance rate. In addition, the regulations set a floor and a ceiling for the number of samples that must be taken in an annual survey cycle regardless of the sample number that would be calculated using the regulatory formula. Therefore, the number of samples required to be taken can potentiall y be less than the formula would require, or it can be more. Compliance with the ULSD sulfur content standard has been extremel y high; less than 1% of the samples have been in violation in recent y ears. The minimum number of samples currentl y required to be taken annually is set b y the regulation at 5,250 regardless of this high compliance rate. Due to the high compliance rate, use of the statistical formula would result in a sampling rate of several hundred samples for each of the past several ye ars, instead of 5,250 samples. The cost difference between taking several hundred s amples versus taking over 5,000 samples is significant. For these reasons we believe the continued high compliance rate, and the*** E.O. 12866 Review

108 substantial discrepancy

between the sampling rate calculated by the formula and the minimum sampling rate, argue for lowering the minimum sampling rate. However, we believe there is a point where the number of samples per ye ar would be so few that the survey would be meaningless relative to robust sampling and testing programs conducted b y each refiner individually . Balancing these concerns, we believe minimum sampling rate of about 1,800 samples is appropriate. We are requesting comment on reducing the minimum number of samples to some rate below 2,000 samples.*** E.O. 12866 Review

109 VI I I. Statutory

and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is a "significant regulatory

action” because it raises novel legal or policy issues. Accordingl y, EPA submitted this action to the Office of Management and Budget (OMB) for review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011) and any

changes made in response to OMB recommendations have been documented in the docket for this action. B. Paperwork Reduction Act The information collection requirements in this notice of proposed rulemaking have been submitted for approval to the Office of Management and Budget (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq . The Information Collection Request (I CR) document prepared b y EPA related to this proposal has been assigned EPA I CR number 2469.01 . A supporting statement for the proposed ICR has been placed in the docket. The proposed information collection is described in the following paragraphs. This action contains recordkeeping and reporting that may affect the following parties under the RFS2 regulation : RI N generators (producers, importers), obligated parties (refiners), exporters, and parties who own or transact RINs . We estimate that 6 7 0 parties may be subject to the proposed information collection. We estimate an annual recordkeeping and reporting burden*** E.O. 12866 Review

110 of 3.1 hours per respondent . This action contains recordkeeping and reporting that may affect the following parties under the E15 regulation: gas oline refiners, gasoline and ethanol importers, gasoline and ethanol blenders (including terminals and carriers). We estimate that 2,000 respondents may

be subject to the proposed information collection. We estimate an annual recordkeeping and reporting burden of 1.3 hours per respondent. Burden means the total time, effort, or financial resources expended b y persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency . This includes the time needed to review the instructions; develop, acquire, install, and utilize technology and s ys tems for the purpose of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to compl y with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transit or otherwise disclose the information. Burden is as defined at 5 CFR § 1320.3(b). An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it display s a currently valid OMB control number. The OMB control numbers for EPA's r egulations in 40 CFR are listed in 40 CFR Part 9. To comment on the Agency ’s need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, EPA has established a public docket for this proposed rule, which includes the ICR described above, under Docket ID number EPA - HQ - OAR - 2012 - 0401 . Submit any comments related to the ICR to EPA and OMB. See the ADDRESSES section at the beginning of this notice for where to*** E.O. 12866 Review

Se nd comments to OMB at the Office of Information and Regulatory Affairs, Office of Management and Budget, 725 17th Street, NW, Washington, DC 20503, Attention: Desk Office for EPA. Since OMB is required to make a decision concerning the IC R between 30 and 60 day s after [insert date of publication of this notice in the Federal Register .], a comment to OMB is best assured of having its full effect if OMB receives it by [insert date 30 day s after publication of this notice in the Federal Register .].

Act (RFA) generall y requires an agency to prepare a regulatory

flexibility

analy sis of any

rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or an y 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 o f assessing the impacts of today 's rule on small entities, small entity is defined as: (1) a small business as defined b y the Small Business Administration’s (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city , count y, 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.*** E.O. 12866 Review

112 After considering the economic impacts of this action on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The amendments to the RFS2 provisions in this direct final rule will not impose any requirements on small entities that were not already considered under the final RFS2 regulations, as it makes relativel y minor corrections and modifications to those regulations. We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts. 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

re quirements that might significantly or uniquel y affect small governments. It only

applies to gasoline, diesel, and renewable fuel producers, importers, distributors and marketers and makes relatively minor corrections and modifications to the RFS2 and die sel regulations. E. Executive Order 13132 (Federalism)*** E.O. 12866 Review

113 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 distrib ution 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 and makes relativel y minor corrections and modifications to the RFS2 and diesel regulations. Thus, Executive Order 13132 does not apply to this action. Inthe spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and State and local governments, EPA specifically solicits comment on this proposed action from State and local officials.

Executive Order 13175 (Consultation and Coordination with Indian Tribal Governments) This proposed rule does not have tribal implications, as s pecified in Executive Order 13175 (65 FR 67249, November 9, 2000). Itapplies to gasoline, diesel, and renewable fuel producers, importers, distributors and marketers. This action makes relatively minor corrections and modifications to the RFS and diesel regulations, and does not impose any enforceable duties on communities of Indian tribal governments. Thus, Executive Order 13175 does not apply to this action. EPA specifically solicits additional comment on this proposed action from tribal officials. G.

1 14 EPA interprets EO 13045 (62 F.R. 19885, April 23, 1997) as appl yi ng only to those regulatory

actions that concern health or safet y risks, such that the anal ys is required under section 5 - 501 of the EO has the potential to influence the regulation. This action is not subject to EO 13045 because it does not establish an environmental standard intended to mitigate health or safet y risks. H. Executive Orde r 13211: Actions Concerning Regulations That Significantly Affect Energy Supply , Distribution, or Use This action is not a “significant energy action” as defined in Executive Order 13211 (66 FR 28355 (May

22, 2001)), because it is not likely to have a si gnificant adverse effect on the supply , distribution, or use of energy . This action amends existing regulations related to renewable fuel, E15, and ultra - lower sulfur diesel. We have concluded that this rule is not likely to have an y adverse energy effec ts. In fact, we expect this proposed rule may result in positive effects, because man y of the changes we are proposing will facilitate the introduction of new renewable fuels under the RFS2 program and have come at the suggestion of industry stakeholders . I. National Technology Transfer and Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (“NTTAA”), Public Law No. 104 - 113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary*** E.O. 12866 Review

115 consensus standards in it s 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) th at are developed or adopted b y 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 an y voluntary consensus standards. EPA welcomes comments on this aspect of the proposed rulemaking and, specificall y, invites the public to identify potentially - applicable voluntary consens us standards and to explain why such standards should be used in this regulation. J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and L ow - Income Populations. Executive Order (EO) 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.*** E.O. 12866 Review

116 EPA has determined that this proposed rule will not have disproportionatel y 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 technical amendments do not relax the control measures on sources regulated by the RFS regulations and therefore will not cause emissions increases from these sources. K . Clean Air Act Section 307(d) This rule is subject to Section 30 7(d) of the CAA. Section 307(d)(7)(B) provides that "[o]nly an objection to a rule or procedure which was raised with reasonable specificit y during the period for public comment (including an y public hearing) may be raised during judicial review." This s ection also provides a mechanism for the EPA to convene a proceeding for reconsideration, "[i]f the person raising an objection can demonstrate to the EPA that it was impracticable to raise such objection within [the period for public comment] or if the grounds for such objection arose after the period for public comment (but within the time specified for judicial review) and if such objection is of central relevance to the outcome of the rule."
