Abstract

The U.S. Environmental Protection Agency (EPA) is co-proposing two approaches to revising the existing 2026 and 2027 small refinery exemption (SRE) reallocation volumes under the Renewable Fuel Standard (RFS) program in response to a higher volume of 2025 SREs than previously projected when the Agency set the renewable fuel volumes and percentage standards on April 1, 2026. One approach would reallocate the additional 2025 SRE volume equally between the 2026 and 2027 SRE reallocation volumes, while the other approach would reallocate all the additional 2025 SRE volume to the 2027 SRE reallocation volume. Additionally, given the proposed revision to the 2026 standards, this proposed action may extend the existing 2026 compliance reporting deadline of March 31, 2027.

Renewable Fuel Standard (RFS) Program: Reallocation of Additional 
2025 Small Refinery Exemptions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The U.S. Environmental Protection Agency (EPA) is co-proposing 
two approaches to revising the existing 2026 and 2027 small refinery 
exemption (SRE) reallocation volumes under the Renewable Fuel Standard 
(RFS) program in response to a higher volume of 2025 SREs than 
previously projected when the Agency set the renewable fuel volumes and 
percentage standards on April 1, 2026. One approach would reallocate 
the additional 2025 SRE volume equally between the 2026 and 2027 SRE 
reallocation volumes, while the other approach would reallocate all the 
additional 2025 SRE volume to the 2027 SRE reallocation volume. 
Additionally, given the proposed revision to the 2026 standards, this 
proposed action may extend the existing 2026 compliance reporting 
deadline of March 31, 2027.

I. Executive Summary

    On April 1, 2026, the EPA established the renewable fuel volumes 
and percentage standards under the RFS program that apply to obligated 
parties for the 2026 and 2027 compliance years (``Set 2 Rule'').\1\ In 
that final rule, the EPA reallocated a portion (70 percent) of the SREs 
granted or projected to be granted for 2023-2025 by including a ``SRE 
reallocation volume'' term in the equations used to calculate the RFS 
percentage standards under 40 CFR 80.1405. For the 2025 compliance 
year, the EPA projected that SREs would result in an exempted Renewable 
Volume Obligation (RVO) of 990 million Renewable Identification Numbers 
(RINs),\2\ resulting in the inclusion of approximately 700 million RINs 
in the 2027 SRE reallocation volume.\3\
---------------------------------------------------------------------------

    \1\ 91 FR 16388 (Apr. 1, 2026).
    \2\ The EPA refers to these 990 million RINs as the ``projected 
2025 exempted RVO'' throughout this preamble.
    \3\ The 2027 SRE reallocation volume also included an additional 
340 million RINs attributable to half of the reallocated 2024 
exempted RVO, for a total 2027 SRE reallocation volume of 1.04 
billion RINs.
---------------------------------------------------------------------------

    On August 31, 2026, the EPA issued decisions on 34 SRE petitions 
under the RFS program for the 2025 compliance year after consulting 
with the U.S. Department of Energy (DOE) and considering relevant 
information pursuant to Clean Air Act (CAA) section 211(o)(9).\4\ The 
2025 SREs granted in that action resulted in a 2025 exempted RVO of 
1.76 billion RINs,\5\ which is 770 million RINs greater than the volume 
projected in the Set 2 Rule.\6\ In this action, the EPA is proposing 
two options for revising the SRE reallocation volumes promulgated in 
the Set 2 Rule to reallocate an additional 770 million RINs as a result 
of this significant increase in the actual 2025 exempted RVO as 
compared to the projected 2025 exempted RVO. This additional SRE 
reallocation volume represents complete (100 percent) reallocation of 
the additional 2025 exempted RVO (i.e., the volume beyond the 990 
million RINs originally projected for 2025) and aims to prevent the 
significantly higher-than-projected volume of 2025 SREs from reducing 
demand for renewable fuel and RINs in 2026 and 2027 to levels lower 
than anticipated in the Set 2 Rule.

Exemptions. EPA-420-R-26-017.
    \5\ The EPA refers to these 1.76 billion RINs as the ``actual 
2025 exempted RVO'' throughout this preamble.
    \6\ The EPA refers to these 770 million RINs as the ``additional 
2025 exempted RVO'' throughout this preamble.
---------------------------------------------------------------------------

    This proposal describes the EPA's legal basis for considering the 
2025 SREs when proposing to revise the 2026 and 2027 SRE reallocation 
volumes, the revised SRE reallocation volumes the Agency is co-
proposing for 2026 and 2027, how the statutory factors were considered, 
and the methodology used to calculate the co-proposed revised 
percentage standards for 2026 and 2027. Specifically, the EPA is co-
proposing two approaches: (1) reallocate the additional 2025 exempted 
RVO equally between the 2026 and 2027 compliance years; and, 
alternatively, (2) reallocate all the additional 2025 exempted RVO to 
the 2027 compliance year.
    Finally, the EPA notes that because the Agency is proposing to 
revise the existing 2026 and 2027 RFS standards under 40 CFR 
80.1405(a), this proposed rule triggers the automatic compliance 
reporting deadline extension provisions under 40 CFR 
80.1451(f)(1)(i)(C). For the 2026 compliance year, the current 
compliance reporting deadline is March 31, 2027. As a result of this 
proposed rule, and per the RFS regulations, the 2026 compliance 
reporting deadline will be extended to whichever of the following dates 
is applicable:
    <bullet> If the EPA finalizes the proposed revision to the 2026 RFS 
standards, the next quarterly reporting deadline after the date the 
revised 2026 RFS standards become effective.
    <bullet> If the EPA withdraws the proposed revision to the 2026 RFS 
standards, the next quarterly reporting deadline that is 60 days after 
the date of the Agency's withdrawal of the proposed revision to the 
2026 RFS standards is published in the Federal Register.
    <bullet> If the EPA does not finalize or withdraw the proposed 
revision to the 2026 RFS standards within 12 months of the date of 
publication of this proposed rule in the Federal Register, the next 
quarterly reporting deadline that is 12 months after the date this 
proposed rule is published in the Federal Register.
    For the 2027 compliance year, there is currently no established 
compliance reporting deadline because the EPA has not yet established 
the 2028 RFS standards.\7\ Furthermore, the earliest the 2027 
compliance reporting deadline could be is March 31, 2028, which is more 
than 16 months after this proposal.\8\ Thus, this proposed rule is not 
expected to have any impact on the 2027 compliance reporting deadline.
---------------------------------------------------------------------------

    \7\ Under 40 CFR 80.1451(f)(1)(i)(A)(2), the compliance 
reporting deadline for a given compliance year is not established 
until the subsequent compliance year's standards become effective in 
40 CFR 80.1405(a).
    \8\ 40 CFR 80.1451(f)(1)(i)(A).
---------------------------------------------------------------------------

II. Background and Policy Rationale

    In the Set 2 Rule, the EPA established applicable volumes for 2026 
and 2027 based on an analysis of the statutory factors and a review of 
implementation of the RFS program to date.\9\ In doing so, the EPA 
determined both the volume requirements, which were intended to be met 
with renewable fuel produced and used in 2026 and 2027, and SRE 
reallocation volumes, which were intended to be met with carryover RINs 
attributable to the 2023-2025 SREs.\10\
---------------------------------------------------------------------------

    \9\ 91 FR 16388, 16425 (Apr. 1, 2026).
    \10\ 91 FR 16388, 16433 (Apr. 1, 2026).
---------------------------------------------------------------------------

    The 2026 and 2027 SRE reallocation volumes established in the Set 2 
Rule accounted for a portion of the actual 2023 and 2024 exempted RVOs 
that resulted from the SRE decisions issued by the EPA in August 2025 
\11\ and November 2025,\12\ as well as a portion of the projected 2025 
exempted RVO.\13\ The SRE reallocation volumes correspond to three 
statutory categories

[[Page 65702]]

of renewable fuel (advanced biofuel, biomass-based diesel (BBD), and 
total renewable fuel), such that there are three SRE reallocation 
volumes for each year.\14\ As discussed in the Set 2 Rule and 
elsewhere, the EPA at the time faced an unusually high backlog of 
pending SRE petitions for multiple compliance years resulting in an 
unusually material impact on overall volumes.\15\

November 2025 Decisions on Petitions for RFS Small Refinery 
Exemptions. EPA-420-R-25-013.
    \13\ The EPA's rationale for creating the SRE reallocation 
volumes can be found in the Set 2 Rule. 91 FR 16388, 16435-40 (Apr. 
1, 2026).
    \14\ The EPA did not establish SRE reallocation volumes for 
cellulosic biofuel for the reasons discussed in the Set 2 Rule. 91 
FR 16388, 16437-38 (Apr. 1, 2026).
    \15\ 91 FR 16388, 16436 (Apr. 1, 2026).
---------------------------------------------------------------------------

    At the time of the Set 2 Rule, the EPA had issued decisions on the 
2023 and 2024 SRE petitions, but not the 2025 SRE petitions. Consistent 
with the approach that the EPA first advanced in the 2020 RFS Rule (in 
which the Agency projected future exempted fuel volumes),\16\ in the 
Set 2 Rule the Agency projected 7.55 billion gallons of exempted fuel 
volume in 2025 using a three-year average of the actual exempted fuel 
volumes from 2022-2024. This projected exempted fuel volume equaled a 
projected 2025 exempted RVO of 990 million RINs. The EPA reallocated 70 
percent of this volume (approximately 700 million RINs) as part of the 
2027 SRE reallocation volume.\17\
---------------------------------------------------------------------------

    \16\ 85 FR 7016, 7051-53 (Feb. 6, 2020) (``2020 RFS Rule''). 
Note that while the EPA projected exempted fuel volumes in the 2020 
RFS Rule, the Agency later revised the 2020 percentage standards via 
rulemaking, including adjusting the projection of exempted volume 
from SREs. 87 FR 39600 (July 1, 2022).
    \17\ The 2027 SRE reallocation volume also included an 
additional 340 million RINs, attributable to half of the reallocated 
2024 exempted RVO, for a total 2027 SRE reallocation volume of 1.04 
billion RINs.
---------------------------------------------------------------------------

    On August 31, 2026, the EPA issued decisions on 34 SRE petitions 
for the 2025 compliance year after consulting with DOE and considering 
relevant information,\18\ in which the Agency granted full (100 
percent) exemptions to 18 petitions, granted partial (50 percent) 
exemptions to 11 petitions, denied three petitions, and determined two 
petitions to be ineligible.\19\ The 2025 SREs resulted in a 2025 
exempted fuel volume of 13.38 billion gallons, which, using the 
previously established percentage standards for 2025, equaled an actual 
2025 exempted RVO of 1.76 billion RINs.\20\ This is 770 million RINs 
greater than the projected 2025 exempted RVO of 990 million RINs in the 
Set 2 Rule.\21\

``2025 SREs'' throughout this preamble.

    \20\ The EPA used estimated gasoline and diesel production 
volumes from 2025 SRE petitions to estimate the actual 2025 exempted 
RVO. Reported 2025 exempted fuel volumes will not be available until 
after the 2025 compliance reporting deadline of October 1, 2026. The 
EPA intends to use reported 2025 compliance data, as well as 
incorporate any additional 2025 SRE decisions issued after this 
proposed rule, in the final rule establishing the revised SRE 
reallocation volumes.
    \21\ 91 FR 16388, 16439 (Apr. 1, 2026).
---------------------------------------------------------------------------

    In this action, the EPA is co-proposing to revise the 2026 and 2027 
SRE reallocation volumes to reallocate an additional 770 million RINs, 
which is 100 percent of the additional 2025 exempted RVO beyond the 
projected 2025 exempted RVO in the Set 2 Rule.\22\ The actual 2025 
exempted RVO was significantly higher than the volume projected by the 
EPA in the Set 2 Rule, resulting in an increased number of RINs 
available for obligated parties to use for compliance with their 2025 
or future RFS obligations. These RINs represent renewable fuel produced 
and used in 2025 that exempt small refineries no longer need to retire 
for compliance because of their relieved obligations due to SREs. The 
availability of these RINs--and the ability for obligated parties to 
use them to comply with their RFS obligations in lieu of RINs generated 
for renewable fuel produced and used in 2026 and 2027--could reduce RIN 
prices and demand for renewable fuel and RINs in future years and may 
ultimately result in the market failing to produce the volume of 
renewable fuel anticipated by the volume requirements in the Set 2 
Rule.
---------------------------------------------------------------------------

    \22\ The exact co-proposed revised SRE reallocation volumes are 
described in section IV of this preamble.
---------------------------------------------------------------------------

    The additional 2025 exempted RVO would have impacts on the RIN 
market. For the 2025 compliance year, the number of RINs that need to 
be retired to meet the 2025 RFS obligations is 770 million RINs fewer 
than the EPA projected in the Set 2 Rule. While these additional RINs 
have no impact on the volume of renewable fuel actually produced and 
used in 2025 since that year is in the past, they directly increase the 
supply of RINs available for other obligated parties to use for 
compliance. As a result, obligated parties will be able to use the RFS 
program's carryover RIN provisions to roll these RINs forward to the 
2026 compliance year and beyond.\23\
---------------------------------------------------------------------------

    \23\ CAA section 211(o)(5) requires that the EPA establish a 
credit program as part of the Agency's RFS regulations and that the 
credits be valid for obligated parties to show compliance for 12 
months after the date of generation. 42 U.S.C. 7545(o)(5). The EPA 
implemented this requirement through the use of RINs, which can be 
used to demonstrate compliance for the year in which they are 
generated and the subsequent compliance year. Obligated parties can 
obtain more RINs than needed in a given compliance year, allowing 
them to carry over these RINs for use in the subsequent compliance 
year, although the RFS regulations limit the use of these carryover 
RINs to 20 percent of the obligated party's RVO. For the total 
number of available carryover RINs to be preserved from one year to 
the next, individual carryover RINs are used for compliance before 
they expire and are replaced with newer vintage RINs that are then 
held for use in the next year. For example, 2025 carryover RINs must 
be used for compliance in 2026 or they will expire. However, the use 
of 2025 RINs to meet up to 20 percent of an obligated party's 2026 
RVO increases the number of 2026 RINs that can then be carried over 
for use in 2027.
---------------------------------------------------------------------------

    The EPA expects that there may be impacts from the increased number 
of carryover RINs as a result of the additional 2025 exempted RVO on 
renewable fuel production and use in 2026 and, more acutely, in 2027. 
Obligated parties could choose to use these additional carryover RINs 
to comply with their 2026 and 2027 RFS obligations in lieu of acquiring 
renewable fuel produced in those years, thereby reducing the demand for 
renewable fuel production and use in those years. Thus, failure to 
mitigate the market impacts of the increased number of carryover RINs 
due to the additional 2025 exempted RVO could result in decreased 
demand for renewable fuel produced in 2026 and 2027. This magnitude of 
carryover RINs has the potential to depress RIN prices and decrease 
demand for renewable fuel in future years.
    While significant quantities of carryover RINs can negatively 
impact the production and use of renewable fuel, carryover RINs also 
play an important role in providing a liquid and well-functioning RIN 
market, as the EPA has stated on multiple occasions.\24\ The continued 
success of the RFS program depends on the RIN market. Carryover RINs 
provide obligated parties compliance flexibility for substantial 
uncertainties in the transportation fuel marketplace.

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

    The EPA is co-proposing two approaches to reallocate the additional 
2025 exempted RVO. Under the first approach, the EPA would reallocate 
the additional 2025 exempted RVO in equal amounts to both the 2026 and 
2027 SRE reallocation volumes.\25\ This approach would result in 
revised 2026 and 2027 SRE reallocation volumes of similar magnitudes. 
In the Set 2 Rule, the EPA established 2026 and 2027 SRE

[[Page 65703]]

reallocation volumes of 0.99 and 1.04 billion RINs, respectively. Under 
the equal reallocation approach, the 2026 and 2027 SRE reallocation 
volumes would each be increased by equal amounts, such that the SRE 
reallocation volume in each year would be approximately 1.4 billion 
RINs. Given the timing of this proposed rule, this approach would 
require obligated parties to acquire additional RINs for the 2026 
compliance year after the compliance year was over.
---------------------------------------------------------------------------

    \25\ The EPA refers to this approach as the ``equal reallocation 
approach'' throughout this preamble.
---------------------------------------------------------------------------

    Under the second approach, the EPA would reallocate all the 
additional 2025 exempted RVO to the 2027 SRE reallocation volume, as 
opposed to equally between 2026 and 2027.\26\ This approach is 
consistent with the approach to SRE reallocation volumes in the Set 2 
Rule, in which all the projected 2025 exempted RVO was reallocated to 
the 2027 SRE reallocation volume, and would ensure that all the 
reallocated volumes from 2025 SREs were reallocated to the same 
compliance year. Under the 2027 reallocation approach, the 2026 SRE 
reallocation volume would remain at 0.99 billion RINs, while the 2027 
SRE reallocation volume would increase from 1.04 billion to 1.81 
billion RINs. Reallocating all the additional 2025 exempted RVO to 2027 
would provide obligated parties with additional time to prospectively 
adjust their compliance strategies given the increase in the 2027 SRE 
reallocation volume, rather than requiring obligated parties to acquire 
additional RINs after the compliance year was over. It would also allow 
the obligated parties to recover the cost of the revised 2027 SRE 
reallocation volume through the revenue received from the sale of 
obligated fuels (i.e., gasoline and diesel), further limiting the 
impact on obligated parties.
---------------------------------------------------------------------------

    \26\ The EPA refers to this approach as the ``2027 reallocation 
approach'' throughout this preamble.
---------------------------------------------------------------------------

    The EPA is proposing to fully reallocate 100 percent of the 
additional 2025 exempted RVO because this approach would align with 
market expectations from the Set 2 Rule and minimize disruptions in the 
market as a result of the 2025 SREs. At the time the EPA promulgated 
the Set 2 Rule, market participants relied on the volumes promulgated 
in that action to inform compliance strategies, including for the 2026 
and 2027 volume requirements, which require the use of specified 
quantities of renewable fuel in 2026 and 2027. Subsequent to the 
promulgation of the Set 2 Rule, the significantly higher-than-projected 
volume of 2025 SREs disrupted those expectations. Without additional 
action by the EPA, the additional 2025 exempted RVO could jeopardize 
the realization of the 2026 and 2027 volume requirements in the market. 
As described in the Set 2 Rule, the EPA designed the SRE reallocation 
volumes as a mechanism to require the use of RINs associated with 2023-
2025 SREs, removing the ability for obligated parties to use those RINs 
to comply with their RFS obligations in lieu of RINs generated for 
renewable fuel produced and used in 2026 and 2027. Absent the SRE 
reallocation volumes, these RINs could reduce RIN demand and RIN prices 
and may ultimately result in the market failing to produce the volume 
of renewable fuel anticipated by the 2026 and 2027 volume 
requirements.\27\ The EPA is therefore proposing to remedy that 
disruption through the required retirement of the 770 million RINs 
associated with the additional 2025 exempted RVO. This increases the 
likelihood that the 2026 and 2027 volume requirements would be realized 
in the market through new renewable fuel production and use rather than 
through the use of carryover RINs attributable to the 2025 SREs. The 
EPA recognizes that this approach is different from the approach to SRE 
reallocation volumes in the Set 2 Rule but the Agency is proposing that 
such change is justified for the reasons articulated in this preamble.
---------------------------------------------------------------------------

    \27\ 91 FR 16388, 16436 (Apr. 1, 2026).
---------------------------------------------------------------------------

    As noted in section IX of this preamble, the EPA is requesting 
comment on whether the additional SRE reallocation volumes should be 
different between 2026 and 2027, such as whether more or less of the 
additional 2025 exempted RVO should be reallocated in 2026 or 2027 (C-
1).

III. Legal Justification

    In this action, the EPA is co-proposing two approaches to revise 
the 2026 and 2027 SRE reallocation volumes established in the Set 2 
Rule. In doing so, the EPA is proposing to use the same authority under 
CAA section 211(o)(2)(B)(ii) that was used to establish the original 
2026 and 2027 SRE reallocation volumes in the Set 2 Rule.\28\ This 
section discusses that authority, as well as the EPA's authority to 
reconsider and revise previously established standards under the RFS 
program. Alternatively, the EPA may have authority under CAA section 
211(o)(2)(A)(i) and (iii)(I) to ``ensure'' that the volumes in the Set 
2 Rule are met in the market with actual renewable fuel production and 
use in 2026 and 2027 via a compliance mechanism.\29\ The purpose of 
reallocating the additional 2025 exempted RVO is to prevent excess 
carryover RINs introduced by the 2025 SREs granted after the Set 2 Rule 
was finalized from removing the market incentives for actual production 
and use of renewable fuels in 2026 and 2027 at the volumes anticipated 
by the Set 2 Rule. As noted in section IX of this preamble, the EPA is 
requesting comment on the Agency's legal authority to reallocate the 
additional 2025 exempted RVO (C-2), including under CAA section 
211(o)(2)(A)(i).

A. Legal Authority for SRE Reallocation Volumes

    As in the Set 2 Rule, the EPA is co-proposing to revise the 2026 
and 2027 SRE reallocation volumes utilizing the ``set authority'' in 
CAA section 211(o)(2)(B)(ii), which directs the Agency to ``set,'' or 
establish, applicable volumes of renewable fuel for use as 
transportation fuel in the U.S. for years after those specified in the 
statutory tables. Under that provision, the Administrator shall, in 
coordination with the Secretary of Agriculture and Secretary of Energy, 
determine the applicable volume of each renewable fuel category based 
on a review of implementation of the RFS program and an analysis of 
statutory factors. Congress provided the EPA flexibility by enumerating 
factors that the Administrator must consider without mandating 
particular forms of analysis or specifying how the Administrator must 
weigh the various factors against one another. Thus, as the CAA ``does 
not state what weight should be accorded to the relevant factors,'' it 
``give[s] EPA considerable discretion to weigh and balance the various 
factors required by statute.'' \30\ There are also prescriptive 
requirements for specific fuel categories in CAA section 
211(o)(2)(B)(iii)-(v).

F.4th 871, 887 (D.C. Cir. 2024); see also Brown v. Watt, 668 F.2d 
1290, 1317 (D.C. Cir. 1981) (``A balancing of factors is not the 
same as treating all factors equally. The obligation instead is to 
look at all factors and then balance the results. The Act does not 
mandate any particular balance, but vests the [agency] with 
discretion to weigh the elements . . . .'').
---------------------------------------------------------------------------

    The EPA is proposing to use this authority to consider the 2025 
SREs and revise the existing SRE reallocation volumes to incorporate 
the additional 2025 exempted RVO. In discussing the statutory 
conditions in CAA section 211(o)(2)(B)(iii) and (v) in the Set 2 Rule, 
the EPA assessed the total applicable volumes, including the 2026 and 
2027 SRE reallocation volumes.

[[Page 65704]]

Because this proposed rule would increase the SRE reallocation volumes 
for individual renewable fuel categories in proportionate amounts 
(i.e., a proportionate increase in the BBD, advanced biofuel, and total 
renewable fuel standards), the EPA points to the discussion of these 
conditions in the Set 2 Rule, which all remain applicable to the 
Agency's proposed action here.\31\

B. Considerations in Revising Established SRE Reallocation Volumes and 
for Timing of This Action

    The EPA generally has authority to reconsider and revise the 
Agency's rulemakings, unless provided otherwise by statute, so long as 
we use the same procedures to amend a rule as we used to promulgate it 
in the first instance and set forth good reasons for the 
reconsideration.\32\ The EPA's authority to revise RFS standards 
specifically is further buttressed by the statutory structure, under 
which Congress created a prospective regulatory scheme \33\ that 
expressly contemplates the possibility of adjustments based on 
unanticipated circumstances.\34\ This understanding of the EPA's 
authority is longstanding; the Agency previously revised the 2011, 
2013, and 2020 annual rules and has also adjudicated on the merits 
numerous petitions to revise other annual rules.\35\ The EPA believes 
the power to reconsider, as with the power to promulgate a rule in the 
first instance, remains extant even if the rule operates retroactively 
or is promulgated after the statutory deadline, so long as the Agency 
reasonably considers and mitigates the burdens associated with a 
retroactive or delayed rulemaking as described in this section.

    The 2026 and 2027 SRE reallocation volumes, established under CAA 
section 211(o)(2)(B)(ii) as a component of the applicable volumes for 
2026 and 2027, are similar to the revisions to the volume requirements 
promulgated in the EPA's prior actions. CAA section 211(o)(2)(B)(i) 
contains the statutory volumes, which can then be modified using the 
EPA's waiver authorities. Likewise, CAA section 211(o)(2)(B)(ii) 
requires the EPA to set volumes after 2022, which can also be modified 
using the Agency's waiver authorities and reconsidered, as appropriate, 
to the extent justified by relevant factors.\36\
---------------------------------------------------------------------------

    \36\ See, e.g., 91 FR 16388, 16397 (Apr. 1, 2026) and 88 FR 
44468, 44479 (July 12, 2023).
---------------------------------------------------------------------------

    The Agency acknowledges that reconsideration can negatively impact 
regulatory certainty and disrupt market expectations created by 
previously promulgated standards. This may especially be the case if 
the effects of reconsideration are retroactive, and such retroactive 
rules must consider and mitigate burdens on obligated parties, as 
discussed further below. Moreover, in the Set 2 Rule, the EPA expressly 
stated that the Agency did not intend, at that time, to revisit that 
rulemaking and subsequently adjust the standards.\37\ Although the EPA 
expects that any reliance interests obligated parties had in the 
percentage standards from the Set 2 Rule would be outweighed by the 
considerations informing this proposal (i.e., the proposed attempt to 
maintain the volumes from the Set 2 Rule in light of the recent 2025 
SREs), as noted in section IX of this preamble, the Agency is 
requesting comment on reliance interests to better inform our decision-
making on this topic (C-3).
---------------------------------------------------------------------------

    \37\ 91 FR 16388, 16441 (Apr. 1, 2026) (``We note, however, that 
we do not plan to revise the percentage standards for 2026 and 2027 
to account for any subsequent changes to our approach to evaluating 
SRE petitions or other inaccuracies in the projection of exempt 
volumes of gasoline and diesel.'').
---------------------------------------------------------------------------

    At the same time, reconsideration can also address the impacts of 
unexpected actions and market disruptions that occur after the 
standards have been set and that, if not accounted for, could lead to 
reduced demand for renewable fuel. In this action, the EPA is co-
proposing to revise the 2026 and 2027 SRE reallocation volumes in 
response to an unanticipated event--the significantly higher-than-
projected volume of 2025 SREs--that has occurred since the promulgation 
of the Set 2 Rule and that could have direct and significant impacts on 
the fuels market. The EPA believes this event has created an unusual 
situation in which retroactive reconsideration and revision of the 2026 
and 2027 SRE reallocation volumes are warranted.
    In the Set 2 Rule, the EPA attempted to account for the exempted 
RVOs associated with 2023-2025 SREs through the establishment of SRE 
reallocation volumes, which included a projection of the 2025 exempted 
RVO that was reallocated to the 2027 compliance year. The projected 
2025 exempted RVO, however, fell short of the actual 2025 exempted RVO 
by a sizeable margin. As described in section II of this preamble, the 
significantly higher-than-projected volume of 2025 SREs resulted in an 
additional 770 million RINs becoming available for compliance with the 
2025 and later compliance years. Consistent with the EPA's 
justification for establishing the 2026 and 2027 SRE reallocation 
volumes in the Set 2 Rule, these excess RINs could result in decreased 
demand in future years for RINs and renewable fuel, as well as 
decreased RIN prices, and may ultimately result in the market failing 
to produce the volume of renewable fuel anticipated by the volume 
requirements established in the Set 2 Rule. This is because, through 
the use of the RFS program's carryover RIN provisions, the additional 
2025 exempted RVO would allow obligated parties to effectively use an 
additional 770 million RINs from the 2025 compliance year to comply 
with their 2026 and 2027 RFS obligations in lieu of RINs generated for 
renewable fuel produced and used in 2026 and 2027.
    The EPA recognizes that in co-proposing to revise the 2026 and 2027 
SRE reallocation volumes, the Agency is doing so after the statutory 
deadlines for the 2026 and 2027 standards of October 31, 2024, and 
October 31, 2025, respectively.\38\ The EPA also recognizes that if 
this rule is finalized in 2026, it will be partially retroactive for 
the 2026 compliance year, and if it is finalized in 2027, it will be 
fully retroactive for the 2026 compliance year and partially 
retroactive for the 2027 compliance year. Additionally, barring unusual 
circumstances, the EPA believes it is generally appropriate to avoid 
reconsidering and revising previously finalized RFS standards.\39\ 
Nonetheless, the EPA is proposing to do so for 2026 and 2027 because 
the Agency has determined that unanticipated events have occurred that 
affect fuel markets

[[Page 65705]]

and consequently affect renewable fuel demand. The EPA additionally 
finds that the burden of such a standard is materially mitigated by the 
fact that the Agency intends for the co-proposed revised SRE 
reallocation volumes to be met using carryover RINs attributable to the 
2025 SREs, which will be available in greater numbers than anticipated 
when the Agency established the 2026 and 2027 standards due to the 
significantly higher-than-projected volume of 2025 SREs.

    The U.S. Court of Appeals for the D.C. Circuit held that the EPA 
retains authority to promulgate volumes and annual standards beyond the 
statutory deadlines, even those that apply retroactively, so long as 
the Agency exercises our authority ``reasonably.'' \40\ In doing so, 
the EPA must balance the burden on obligated parties of a delayed 
rulemaking with the broader goal of the RFS program to increase 
renewable fuel use.\41\ The D.C. Circuit noted reasonableness includes 
``whether obligated parties had adequate lead time and access to a 
sufficient number of RINs to comply with the delayed requirement.'' 
\42\ In upholding the EPA's late and retroactive standards in ACE, the 
D.C. Circuit considered several specific factors, including the 
availability of RINs for compliance, the amount of lead time and 
adequate notice for obligated parties, and the availability of 
compliance flexibilities.\43\ In addressing rulemakings that were late 
(i.e., those issued after the statutory deadline) but not retroactive, 
the D.C. Circuit emphasized the amount of lead time and adequate notice 
for obligated parties.\44\ In 2015, the EPA established the BBD volume 
requirements for 2014-2017 and missed the statutory deadline--that the 
Agency establish an applicable volume target for BBD no later than 14 
months before the first year to which that volume requirement will 
apply--for all four years.\45\ The D.C. Circuit found that the EPA 
properly balanced the relevant considerations and had provided 
sufficient notice to parties in establishing the applicable volume 
requirements for 2014-2017.\46\ The D.C. Circuit, in a later case, 
noted its repeated holdings that the ``EPA may promulgate late, and 
even retroactive, volume requirements so long as it `reasonably 
considers and mitigates any hardship caused to obligated parties by 
reason of the lateness.' '' \47\ In so holding, the D.C. Circuit noted 
the EPA's explanation of the achievability of the RFS standards, the 
timing of compliance demonstrations in relation to the final rule, and 
existing flexibilities in the RFS program for obligated parties.\48\

    As described in section I of this preamble, this action triggers 
the automatic compliance reporting deadline extension provisions under 
40 CFR 80.1451(f)(1)(i)(C). For the 2026 compliance year, obligated 
parties will have at least five months after this proposed rule is 
published in the Federal Register before they have to demonstrate 
compliance with their 2026 RFS obligations by the current 2026 
compliance reporting deadline of March 31, 2027, and could have 
additional time for compliance (e.g., until June 1, 2027) depending on 
when the EPA finalizes any of these proposed changes. While the 2027 
compliance reporting deadline will not be determined until the EPA 
establishes the 2028 RFS standards, the deadline can be no earlier than 
March 31, 2028, which is over 16 months after this proposal.\49\ This 
proposed rule also provides notice to obligated parties that their RFS 
obligations for 2026 and 2027 may be increasing. It is possible that 
the revised 2026 and 2027 SRE reallocation volumes will be partly or 
fully retroactive, depending on the timing of the final rulemaking and 
the approach that the EPA finalizes. Under either approach, there are 
concerns with notice and potential retroactive effects if this rule is 
finalized in 2027, though obligated parties are on notice in advance of 
2027 for the potential adjustments to the 2027 SRE reallocation volume 
under either co-proposed approach. If the equal reallocation approach 
is adopted, notice for the revised 2026 SRE reallocation volume would 
primarily amount to this proposed rule, provided in late 2026.\50\ The 
EPA will endeavor to work quickly to minimize retroactive effects of 
this action and will also consider these issues in determining the 
Agency's final approach.
---------------------------------------------------------------------------

    \49\ 40 CFR 80.1451(f)(1)(i)(A).
    \50\ The EPA notes, however, that additional notice was provided 
by the press release issued on August 31, 2026, indicating the 
Agency's intention to issue this proposed rule. U.S. Environmental 
Protection Agency. (August 31, 2026). EPA Announces Action on 2025 
Small Refinery Exemptions and Related Actions. <a href="https://www.epa.gov/newsreleases/epa-announces-action-2025-small-refinery-exemptions-and-related-actions">https://www.epa.gov/newsreleases/epa-announces-action-2025-small-refinery-exemptions-and-related-actions</a>.
---------------------------------------------------------------------------

    RIN acquisition to comply with revised 2026 standards would likely 
occur late in the compliance year, or even after the compliance year is 
over, resulting in obligated parties retroactively adjusting compliance 
strategies as compared to the 2027 reallocation approach. Under the 
2027 reallocation approach, an increased obligation in 2027 only would 
give obligated parties notice of the revised 2027 standards prior to 
the 2027 compliance year so that those parties would have advanced 
notice of their increased obligations and limit the retroactive effects 
of the revised 2027 SRE reallocation volume.
    Because the EPA anticipates that the 770 million RINs associated 
with the additional 2025 exempted RVO will be available in the market 
as carryover RINs, obligated parties should be able to acquire the 
necessary RINs prior to demonstrating compliance with their 2026 and 
2027 RFS obligations. The EPA anticipates that additional information 
will be available at the time of the final rulemaking; the Agency plans 
to further assess the feasibility and market impacts of the revised SRE 
reallocation volumes at that time. While this proposed rule would 
require a drawdown in the number of carryover RINs available, 
additional carryover RINs should remain available for obligated parties 
given the EPA's prior action in the Set 2 Rule to reallocate less than 
the full amount of the 2023-2025 exempted RVOs. Additionally, obligated 
parties would continue to have the ability to use existing compliance 
flexibilities to comply with the revised SRE reallocation volumes, 
including carrying forward a deficit from one compliance year into the 
next.

IV. Co-Proposed Revised SRE Reallocation Volumes

    As described in section II of this preamble, the EPA is co-
proposing two approaches to revise the 2026 and 2027 SRE reallocation 
volumes. Both approaches would increase the total 2026 and 2027 SRE 
reallocation volumes by 770 million RINs, which is equivalent to 100 
percent of the additional 2025 exempted RVO beyond the projected 2025 
exempted RVO of 990 million RINs from the Set 2 Rule. Under the equal 
reallocation approach, the additional 770 million RINs would be 
reallocated equally between the 2026 and 2027 compliance years. Under 
the 2027 reallocation approach, the additional 770 million RINs would 
be reallocated only to the 2027 compliance year, and no changes would 
be made to

[[Page 65706]]

the 2026 RFS standards. The resulting co-proposed revised SRE 
reallocation volumes, as well as the existing SRE reallocation volumes, 
are shown in Table IV-1.

----------------------------------------------------------------------------------------------------------------
Note: All volumes are rounded to the nearest 10 million RINs. To avoid overestimating, volumes ending in five
  were rounded down for 2026 and rounded up for 2027.

    The EPA is not reopening the analyses supporting the 2026 and 2027 
SRE reallocation volumes established in the Set 2 Rule, which the 
Agency established prospectively as a mechanism to preserve the 
stringency of the 2026 and 2027 volume requirements. The 2026 and 2027 
SRE reallocation volumes promulgated in the Set 2 Rule continue to be 
fully justified by the decisions in that action and represented the 
EPA's understanding of the proper SRE reallocation volumes in light of 
the information before the Agency at that time. The updated analysis 
provided here in support of the proposed revision represents a 
supplemental analysis to the determinations made in the Set 2 Rule that 
the EPA is not reopening. In this action, the EPA is proposing to 
revise the 2026 and 2027 SRE reallocation volumes by increasing the SRE 
reallocation volumes to account for the 2025 SREs as reflected in Table 
IV-1. The EPA requests that commenters limit their input to whether 
this is the appropriate response considering the 2025 SREs, and refrain 
from commenting on other aspects of the Set 2 Rule, including the 
renewable fuel volume requirements promulgated therein or other final 
actions in that rulemaking.

V. Co-Proposed Revised Percentage Standards

    The obligated parties to which the percentage standards apply are 
producers and importers of gasoline and diesel, as defined by 40 CFR 
80.2. Each obligated party multiplies the percentage standards by the 
sum of all non-renewable gasoline and diesel they produce or import to 
determine their RVOs.\51\ The RVOs are the number of RINs that the 
obligated party is responsible for procuring and retiring to 
demonstrate compliance with the applicable standards for that year. 
Since there are four categories of renewable fuel under the RFS 
program, there are likewise four RVOs applicable to each obligated 
party for each year. As described in section IV of this preamble, the 
EPA is proposing to revise the 2026 and 2027 SRE reallocation volumes.
---------------------------------------------------------------------------

    \51\ 40 CFR 80.1407.
---------------------------------------------------------------------------

    The formulas used to calculate the percentage standards for the 
2026 and 2027 compliance years applicable to obligated parties are 
provided in 40 CFR 80.1405(c). The EPA used the same values from the 
Set 2 Rule for the variables in these formulas other than the SRE 
reallocation volume (SRERV) to calculate the co-proposed revised 
percentage standards for 2026 and 2027 for both the equal reallocation 
and 2027 reallocation approaches. The resultant percentage standards 
under both co-proposals, as well as the original percentage standards 
in the Set 2 Rule, are shown in Table V-1.\52\ These percentage 
standards are included in the proposed regulations at 40 CFR 80.1405(a) 
and would apply to producers and importers of gasoline and diesel.\53\

standards is presented in ``Calculation of Co-Proposed Revised 2026

VI. Statutory Factor Analysis

    The EPA considered the statutory factors specified in CAA section 
211(o)(2)(B)(ii) in establishing the renewable fuel volumes and 
percentage standards for 2025 in the Set 1 Rule \54\ and for 2026 and 
2027 in the Set 2 Rule. In light of the significantly higher-than-
projected volume of 2025 SREs, the purpose of this proposed rule is to 
account for the difference between the projected 2025 exempted RVO in 
the Set 2 Rule and the actual 2025 exempted RVO. Absent this action, 
the significantly higher-than-projected volume of 2025 SREs could 
significantly increase the number of carryover RINs available for use 
in 2026 and 2027,

[[Page 65707]]

which could in turn reduce RIN prices and demand for RINs and renewable 
fuel in those years. This could also affect some of the statutory 
factors, including the expected annual rate of future commercial 
production of renewable fuels, as discussed further below.
---------------------------------------------------------------------------

    \54\ 88 FR 44468 (July 12, 2023) (``Set 1 Rule'').
---------------------------------------------------------------------------

    The EPA acknowledges that neither this action nor the 2025 SREs 
will affect the volume of renewable fuel produced or consumed in the 
U.S. in 2025, and that any effect these decisions may have on renewable 
fuel production and use in 2026 is limited. Instead, the significantly 
higher-than-projected volume of 2025 SREs will result in fewer RINs 
being retired for compliance in 2025 and, all else being equal, a 
higher number of carryover RINs being available for use in 2026 and 
future years. Increased numbers of carryover RINs can negatively impact 
the demand for RINs and renewable fuel. This is because obligated 
parties can use carryover RINs to meet their compliance obligations in 
2026 and 2027 in lieu of acquiring RINs generated for renewable fuel 
produced and used in these years. An increase in the availability of 
carryover RINs to meet obligated parties' 2026 and 2027 RFS obligations 
could decrease the demand for current-year RINs. The co-proposed 
revised SRE reallocation volumes are intended to prevent increased 
numbers of carryover RINs from decreasing demand for renewable fuel 
below the volumes established for 2026 and 2027 in the Set 2 Rule.
    The EPA is co-proposing revised 2026 and 2027 SRE reallocation 
volumes as part of setting overall RFS applicable volumes pursuant to 
the Agency's authority in CAA section 211(o)(2)(B)(ii). As discussed in 
section III.A of this preamble, the CAA requires that renewable fuel 
volumes established using this authority are based on a review of 
implementation of the program and an analysis of statutory factors.
    The EPA is considering the significantly higher-than-projected 
volume of 2025 SREs under the Agency's directive to review the 
implementation of the program. These exemptions have a direct impact on 
the RFS obligations both for the exempted small refineries (which now 
have reduced or zero RFS obligations) and for all obligated parties in 
aggregate (which can now carry over a greater number of carryover RINs 
into the 2026 and later compliance years). Further, because obligated 
parties can now use the carryover RINs that otherwise would have been 
retired for compliance but for the 2025 SREs, exemptions granted in one 
year can have an impact on the demand for RINs and renewable fuel in 
future years.
    The EPA has also considered the statutory factors specified in CAA 
section 211(o)(2)(B)(ii) in co-proposing the revised 2026 and 2027 SRE 
reallocation volumes. The EPA projects that the portion of the RFS 
obligations represented by the co-proposed revised SRE reallocation 
volumes would be met with carryover RINs attributable to the 2025 SREs. 
The EPA therefore does not expect that this action will increase the 
production and use of renewable fuel beyond the volumes previously 
established for 2026 and 2027 (24.02 billion RINs and 24.46 billion 
RINs, respectively). Conversely, if the EPA does not account for the 
additional 2025 exempted RVO, the increase in available carryover RINs 
resulting from the 2025 SREs could result in lower commercial 
production of renewable fuel in 2026 and 2027 than intended when 
establishing the required volumes for these years in the Set 2 Rule.
    In general, the statutory factors that the EPA must consider when 
establishing the applicable volumes for years after 2022 are impacted 
by the production and use of renewable fuel and are not impacted by the 
use of carryover RINs. Increased production of renewable fuel is 
expected to have impacts on ``air quality, climate change, conversion 
of wetlands, ecosystems, wildlife habitat, water quality, and water 
supply,'' ``energy security,'' ``infrastructure,'' ``job creation, the 
price and supply of agricultural commodities, rural economic 
development, and food prices,'' among other factors.\55\ The use of 
carryover RINs to satisfy RFS obligations is not expected to impact 
these factors. Given this proposed rule's purpose in maintaining the 
volumes established for 2026 and 2027 in the Set 2 Rule, the EPA has 
also considered the impact on the expected annual rate of future 
commercial production of renewable fuels.\56\ The EPA intends that this 
proposed rule, if finalized, would not result in an impact on the 
expected annual rate of future commercial production of renewable fuels 
in 2026 and 2027.
---------------------------------------------------------------------------

    \55\ 42 U.S.C. 7545(o)(2)(B)(ii).
    \56\ In developing this action, the EPA also considered the 
statutory factors that are impacted by the production of renewable 
fuel. See U.S. Environmental Protection Agency. (March 2026). 
Renewable Fuel Standard (RFS) Program: Standards for 2026 and 2027, 
Partial Waiver of the 2025 Cellulosic Biofuel Volume Requirement, 
and Other Changes: Regulatory Impact Analysis. EPA-420-R-26-011 
(``Set 2 Rule RIA'').
---------------------------------------------------------------------------

    This proposed rule is intended to account for the anticipated 
market impacts of the additional 2025 exempted RVO rather than to 
propose changes that would result in higher (or lower) volumes of 
renewable fuel than previously established for 2026 and 2027. In the 
Set 2 Rule, the EPA analyzed the impact of the volume requirements for 
2026 and 2027 in relation to the No RFS Baseline.\57\ The EPA believes 
this analysis remains proper, as this proposed rule seeks to maintain 
the production and use of renewable fuel volumes in the Set 2 Rule. The 
EPA has therefore largely not revised the Agency's analysis of the 
impact of the renewable fuel volumes for 2026 and 2027 on the statutory 
factors presented in the Set 2 Rule and the Set 2 Rule RIA, as we do 
not project that this proposed rule would result in renewable fuel 
production and use in 2026 and 2027 that differs materially from the 
volumes previously analyzed.
---------------------------------------------------------------------------

    \57\ The No RFS Baseline is the EPA's projection of the quantity 
of renewable fuel that would be used in the absence of the RFS 
volume requirements. For more information on the EPA's projection of 
the No RFS Baseline for 2026 and 2027, see Chapter 2 of the Set 2 
Rule RIA.
---------------------------------------------------------------------------

    The co-proposed revised SRE reallocation volumes would result in 
higher percentage standards for obligated parties than would otherwise 
be the case, which in turn would require obligated parties to acquire 
greater quantities of RINs to retire for compliance. The EPA projects 
that, in aggregate, obligated parties would acquire these additional 
RINs by purchasing carryover RINs from other parties rather than 
blending additional quantities of renewable fuel. Because the EPA does 
not expect this action to result in an increase in the production and 
use of renewable fuel, the Agency does not anticipate impacts on most 
statutory factors.
    The one statutory factor that the EPA does project would be 
impacted by this proposed rule is the impact of the use of renewable 
fuels on the cost to consumers of transportation fuel and on the cost 
to transport goods. The EPA does expect that, on average at the 
national level, obligated parties would likely pass on the costs of 
purchasing these additional RINs to consumers, and that this proposed 
rule could increase the cost of transportation fuel to consumers. The 
EPA's assessment of the impacts of this proposed rule on fuel prices 
are shown in Table VI-1.\58\ The EPA has updated the RIN prices in this 
analysis to use average RIN prices for the most recent six months for 
which

[[Page 65708]]

data were available (March 2026-August 2026), which reflects the higher 
market prices for RINs since the release of the Set 2 Rule. For both 
sets of co-proposed percentage standards, the impact of the proposed 
revised SRE reallocation volumes is projected to increase the price of 
gasoline and diesel by less than one cent per gallon relative to the 
projected price impact of the existing 2026 and 2027 RFS standards.

  standard.

    In the Set 2 Rule, the EPA determined the appropriate renewable 
fuel volume requirements (i.e., the volume of renewable fuel expected 
to be produced and used in 2026 and 2027) informed by consideration of 
the statutory factors. This action does not modify or reopen those 
volumes, which continue to be justified by the analysis in the Set 2 
Rule.

VII. Technical Amendments

    The EPA is proposing several technical amendments to the fuel 
quality and RFS regulations. These amendments are being made to correct 
minor inaccuracies in the current regulations. These changes are 
described in Table VII-1.

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

VIII. Severability

    If finalized, the EPA intends for the revised 2026 and 2027 SRE 
reallocation volumes to be severable from the remainder of the 2026 and 
2027 volume requirements. The EPA's justification for each volume is 
independent, such that invalidation of the SRE reallocation volumes 
would not impact the Agency's estimates of renewable fuel that are 
associated with new renewable fuel production in the market in 2026 and 
2027. The EPA's justification for the revised SRE reallocation volumes 
is independent of that establishing the 2026 and 2027 volume 
requirements in the Set 2 Rule, even though the two terms are additive. 
The EPA does not believe that it would be appropriate to further delay 
implementation of the 2026 and 2027 volume requirements if a court were 
to find defects in the revised SRE reallocation volumes.
    The EPA also intends for the revised SRE reallocation volumes to be 
severable from each of the technical corrections in section VII of this 
preamble, as each is independently justified and each function 
separately from the others.

IX. Requests for Comment

    The EPA is specifically soliciting comments on key aspects of the 
proposed rule. To facilitate comment on those portions of the rule, the 
EPA has indexed each comment solicitation with a unique identifier 
below (e.g., ``C-1'', ``C-2'') to provide a consistent framework for 
effective and efficient provision of comments. Accordingly, the EPA 
asks that commenters include the corresponding identifier when 
providing comments relevant to that comment solicitation. The EPA asks 
that commenters include the identifier either in a heading or within 
the text of each

[[Page 65709]]

comment to make clear which comment solicitation is being addressed. 
The EPA notes that the Agency is not limiting comment to these 
identified areas. Specifically, the EPA is requesting comment on the 
following:
    <bullet> How should the EPA reallocate the additional SRE 
reallocation volume between 2026 and 2027 (C-1).
    <bullet> The EPA's legal authority to revise the SRE reallocation 
volumes to reallocate the additional 2025 exempted RVO (C-2).
    <bullet> Any relevant arguments and information, including with 
respect to legitimate reliance interests on the Set 2 Rule (C-3) and 
possible effects of the reallocation proposals.

X. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.

A. Executive Order 12866: Regulatory Planning and Review

    This action is an economically significant regulatory action that 
was submitted to the Office of Management and Budget (OMB) for review. 
Any changes made in response to OMB recommendations have been 
documented in the docket.

B. Executive Order 14192: Unleashing Prosperity Through Deregulation

    This action is expected to be an Executive Order 14192 regulatory 
action.

C. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA. OMB has previously approved the information collection 
activities related to this proposed rule and has assigned the following 
OMB control numbers: 2060-0725, 2060-0740, and 2060-0749. This action 
co-proposes revised SRE reallocation volumes and percentage standards 
for 2026 and 2027 and does not impose new or different reporting 
requirements on regulated parties than already exist for the RFS 
program.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
small entities directly regulated by the annual percentage standards 
associated with the RFS volumes are small refiners that produce 
gasoline or diesel fuel, which are defined at 13 CFR 121.201. The EPA 
believes that there are currently six refiners (owning seven 
refineries) producing gasoline and/or diesel that meet the definition 
of small entity by having 1,500 employees or fewer. To evaluate the 
impacts of the co-proposed revised SRE reallocation volumes on small 
entities, the EPA has conducted a screening analysis to assess whether 
the Agency should make a finding that this action will not have a 
significant economic impact on a substantial number of small 
entities.\59\
---------------------------------------------------------------------------

    \59\ ``Regulatory Flexibility Act Screening Analysis for 
Reallocation of Additional 2025 Small Refinery Exemptions Proposed 
Rule,'' available in the docket for this action.
---------------------------------------------------------------------------

    This action does not change the compliance flexibilities currently 
offered to small entities under the RFS program and currently available 
information shows that the impact on small entities from implementation 
of this rule will not be significant. The EPA has reviewed and assessed 
the available information, which shows that obligated parties, in 
general on a nationwide scale, are able to recover the cost of 
acquiring the RINs necessary for compliance with the RFS standards 
through higher sales prices of the petroleum products they sell than 
would be expected in the absence of the RFS program.\60\ This is true 
whether obligated parties acquire RINs by purchasing renewable fuel 
with attached RINs or purchasing separated RINs. The costs of the RFS 
program are thus being passed on to consumers in a highly competitive 
marketplace. Even if the EPA were to assume that the cost of acquiring 
RINs was not recovered by obligated parties, a cost-to-sales ratio test 
shows that the costs to small entities of the co-proposed revised RFS 
standards in this action are less than one percent of the value of 
their sales.\61\

parties to recover the cost of RINs, see e.g., U.S. Environmental

properly considered RIN cost passthrough in setting the volume 
requirements in the Set 1 Rule, and acknowledging the ``central 
premise'' that ``refineries are able to pass RIN costs along to 
consumers'' as generally true.

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

    While the screening analysis described above supports a 
certification that this rule will not have a significant economic 
impact on small refiners, the EPA continues to believe that it is more 
appropriate to consider the 2026 and 2027 standards as a part of the 
Agency's ongoing implementation of the overall RFS program. When 
considered this way, the impacts of the RFS program as a whole on small 
entities were addressed in the RFS2 Rule, which was the rule that 
implemented the entire program as required by the Energy Independence 
and Security Act (EISA) of 2007.\62\ As such, the Small Business 
Regulatory Enforcement Fairness Act (SBREFA) panel process that took 
place prior to the RFS2 Rule was also for the entire RFS program and 
looked at impacts on small refiners through the full implementation of 
the statutory volume targets, which continue to exceed the volumes 
proposed in this action.
---------------------------------------------------------------------------

    \62\ 75 FR 14670 (Mar. 26, 2010) (``RFS2 Rule'').
---------------------------------------------------------------------------

    For the SBREFA process for the RFS2 Rule, the EPA analyzed the 
potential impacts of the RFS regulations on small entities. As a part 
of this analysis, the EPA convened a Small Business Advocacy Review 
(SBAR) Panel (``the Panel''). During the Panel process, the EPA 
gathered information and recommendations from Small Entity 
Representatives (SERs) on how to reduce the impact of the rule on small 
entities, and those comments are detailed in the Final Panel 
Report.\63\ The EPA also conducted an analysis of the potential impacts 
of the RFS program on all refiners, including small refiners, and found 
that the program would not have a significant economic impact on a 
substantial number of small entities.\64\ For small refiners subject to 
the RFS program, the analysis included a cost-to-sales ratio test, a 
ratio of the estimated annualized compliance costs to the value of 
sales per company. From this test, the EPA estimated that all directly 
regulated small entities would have compliance costs less than one 
percent of their sales over the full implementation of the statutory 
volume targets.\65\ Furthermore, the EPA conducted a section 610 review 
of the RFS program in May 2020, in which the Agency was required to 
determine whether the RFS program should continue without change or 
should be rescinded or amended, consistent with the stated objectives 
of the CAA, to minimize any significant economic impact of the rule 
upon a substantial

[[Page 65710]]

number of small entities.\66\ Following a review of relevant evidence, 
the EPA did not identify any such potential changes that would reduce 
burden on a substantial number of small entities in a manner consistent 
with the stated objectives of the CAA or EISA and concluded that no 
changes to the RFS program were warranted.\67\

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

    The EPA has determined that this action will not impose any 
additional requirements on small entities beyond those already 
analyzed, since the impacts of this rule are not greater or 
fundamentally different than those already considered in the analysis 
for the RFS2 Rule assuming full implementation of the statutory volume 
targets. While in this action the EPA is co-proposing to revise the 
2026 and 2027 SRE reallocation volumes through the Agency's authority 
in CAA section 211(o)(2)(B)(ii) rather than reducing the statutory 
volumes through our waiver authorities (as was the case through 2022), 
the magnitude of the co-proposed revised advanced biofuel and total 
renewable fuel applicable volumes in this action nonetheless remain 
significantly below the statutory volume targets analyzed in the RFS2 
Rule.\68\ Compared to the burden that would be imposed under the 
volumes that the EPA assessed in the analysis for the RFS2 Rule (i.e., 
the volumes specified in the CAA), the volumes in this action would 
reduce burden on small entities. Regarding the BBD standard, it is a 
nested standard within the advanced biofuel category and, as discussed 
in the Set 2 Rule, the BBD applicable volumes for 2026 and 2027 are 
below the volume of BBD that is anticipated to be produced and used to 
satisfy the advanced biofuel and total renewable fuel requirements.\69\ 
In other words, the volume of BBD actually used in 2026 and 2027 will 
be driven not by the 2026 and 2027 BBD standards, but rather by the 
2026 and 2027 advanced biofuel and total renewable fuel standards. The 
net result of the revised volumes being co-proposed in this action is a 
reduction in burden as compared to implementation of the statutory 
volume targets assumed in the RFS2 Rule analysis.
---------------------------------------------------------------------------

    \68\ The statutory volume targets analyzed in the RFS2 Rule were 
21 billion gallons of advanced biofuel and 36 billion gallons of 
total renewable fuel.
    \69\ 91 FR 16388, 16429 (Apr. 1, 2026).
---------------------------------------------------------------------------

    Furthermore, to the degree that small entities may be impacted by 
this action, these impacts are mitigated by the existing compliance 
flexibilities in the RFS program that are available to small entities, 
which the EPA is not proposing to change in this rule. These 
flexibilities include being able to comply through RIN trading rather 
than renewable fuel blending, 20 percent RIN rollover allowance (i.e., 
up to 20 percent of an obligated party's RVO can be met using previous-
year RINs), and deficit carry-forward (i.e., the ability to carry over 
a deficit from a given year into the following year, provided that the 
deficit is satisfied together with the next year's RVO). Additionally, 
as required by CAA section 211(o)(9)(B), the RFS regulations include a 
hardship relief provision that allows for a small refinery to petition 
for an extension of its small refinery exemption at any time based on a 
showing that the refinery is experiencing a ``disproportionate economic 
hardship.'' \70\ The RFS regulations provide the same relief to small 
refiners that are not eligible for small refinery relief.\71\ In the 
RFS2 Rule, the EPA discussed other potential small entity flexibilities 
that had been suggested by the Panel or through comments, but the 
Agency did not adopt them, in part because we had serious concerns 
regarding our legal authority to do so.\72\

    \71\ 40 CFR 80.1442(h).
    \72\ 75 FR 14670, 14858-62 (Mar. 26, 2010).
---------------------------------------------------------------------------

    In sum, this rule would not change the compliance flexibilities 
currently offered to small entities under the RFS program and available 
information shows that the impact on small entities from implementation 
of this rule would not be significant. The EPA has therefore concluded 
that this action will not have any significant adverse economic impact 
on directly regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million 
(adjusted annually for inflation) or more (in 1995 dollars) as 
described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or 
uniquely affect small governments.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have Tribal implications as specified in 
Executive Order 13175. This action will be implemented at the Federal 
level and affects transportation fuel refiners, blenders, marketers, 
distributors, importers, exporters, and renewable fuel producers and 
importers. Tribal governments will be affected only to the extent they 
produce, purchase, or use regulated fuels. Thus, Executive Order 13175 
does not apply to this action.

H. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. Therefore, this action is not 
subject to Executive Order 13045 because it co-proposes SRE 
reallocation volumes and revised percentage standards for 2026 and 2027 
and does not concern an environmental health risk or safety risk. Since 
this action does not concern human health, the EPA's Policy on 
Children's Health also does not apply.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not a ``significant energy action'' because it is 
not likely to have a significant adverse effect on the supply, 
distribution, or use of energy. This action co-proposes SRE 
reallocation volumes and revised percentage standards for 2026 and 
2027. The RFS program is designed to achieve positive effects on the 
Nation's transportation fuel supply by increasing energy independence 
and security.

J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR 
Part 51

    This action does not involve technical standards.

XI. Statutory Authority

    Statutory authority for this action comes from sections 114, 203-
05, 208, 211, 301, and 307 of the CAA, 42 U.S.C. 7414, 7522-24, 7542, 
7545, 7601, and 7607.
