ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 80

[EPA-HQ-OAR-2012-0223; FRL – ]

Regulation of Fuels and Fuel Additives: Modifications to Renewable Fuel Standard

and Diesel Sulfur Programs

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct Final Rule.

SUMMARY: EPA is issuing this direct final rule to amend the definition of heating oil 

in 40 CFR § 80.1401 in the Renewable Fuel Standard (“RFS” or “RFS2”) program under 

section 211(o) of the Clean Air Act. This amendment will expand the scope of renewable 

fuels that can generate Renewable Identification Numbers (RINs) as heating oil to 

include fuel oil produced from qualifying renewable biomass that will be used to generate 

heat to warm buildings or other facilities where people live, work, recreate, or conduct 

other activities. Fuel oils used to generate process heat, power, or other functions will not 

be included in the amended definition. Producers or importers of fuel oil that meets the

amended definition of heating oil will be allowed to generate RINs, provided that the fuel 

oil meets the other requirements specified in the RFS regulations. This amendment will

not modify or limit fuel included in the current definition of heating oil at 40 CFR §

80.2(ccc). EPA is also amending the requirements under EPA’s diesel sulfur program 

related to the sulfur content of locomotive and marine diesel fuel produced by transmix 

processors. These amendments will allow locomotive and marine diesel fuel produced

by transmix processors to meet a maximum 500 parts per million (ppm) sulfur standard 

provided that; the fuel is used in older technology locomotive and marine engines that do 

not require 15 ppm sulfur diesel fuel, the fuel is used outside of the Northeast MidAtlantic Area, and the fuel is kept segregated from other fuel. These amendments will 

provide significant regulatory relief for transmix processors while having a neutral or net 

positive environmental impact. EPA is also amending the fuel marker requirements for 

500 ppm sulfur locomotive and marine (LM) diesel fuel to address an oversight in the 

original rulemaking where the regulations failed to incorporate provisions described in 

the rulemaking preamble to allow for solvent yellow 124 marker to transition out of the 

distribution system. 

DATES: This rule is effective on [insert date 60 days after the date of publication in 

the Federal Register] without further notice, unless EPA receives adverse comment or a 

public hearing request by [insert date 30 days after the date of publication in the 

Federal Register]. If EPA receives a timely adverse comment or a hearing request on 

the rule or any specific portion of this rule, we will publish a withdrawal of the rule or a 

specific portion of the rule in the Federal Register informing the public that the rule or 

portions of the rule with adverse comment will not take effect. If a public hearing is 

requested, we will publish a notice in the Federal Register announcing the date and 

location of the hearing at least 14 days prior to the hearing.

A. Purpose

EPA is issuing a direct final rule to amend provisions in the renewable fuel 

standard (RFS) and diesel sulfur fuel programs. The RFS amendment changes the 

definition of home heating oil, and the diesel sulfur amendments provide additional 

flexibility for transmix processors who produce locomotive and marine diesel fuel, and 

allow solvent yellow 124 marker to transition out of the distribution system. EPA is 

taking this action under section 211 of the Clean Air Act. 

B. Summary of Today’s Rule

Amended Definition of Home Heating Oil

This rule amends the definition of heating oil in 40 CFR § 80.1401 in the

renewable fuel standard (“RFS” or “RFS2”) program promulgated under section 211(o) 

of the Clean Air Act (CAA). This amendment will expand the scope of renewable fuels 

that can generate Renewable Identification Numbers (“RINs”) as “home heating oil” to 

include fuel oil that will be used to generate heat to warm buildings or other facilities 

where people live, work, recreate, or conduct other activities. This rule will allow 

producers or importers of fuel oil that meets the amended definition of heating oil to 

generate RINs, provided that other requirements specified in the regulations are met. 

Fuel oils used to generate process heat, power, or other functions will not be approved for 

RIN generation under the amended definition of heating oil. The amendment will not 

modify, limit, or change fuel included in the current definition of heating oil at 40 CFR § 

80.2(ccc). 

Diesel Transmix Amendments

The diesel transmix amendments will reinstate an allowance for transmix 

processors to produce 500 ppm sulfur diesel fuel for use in older technology locomotive 

and marine diesel outside of the Northeast Mid-Atlantic Area after 2014. EPA’s oceangoing vessels rule forbade this allowance beginning 2014 because a new stream of diesel, 

containing up to 1000 ppm sulfur, was introduced at that time, which we believed would 

provide a suitable outlet for transmix distillate product. Transmix processors stated that 

they were not aware of the changes to the 500-ppm LM transmix provisions until after 

they were finalized, and that the ocean-going vessels market would not be a viable outlet 

for their distillate product. Based on additional input that we received from transmix 

processors and other stakeholders in the fuel distribution system during our consideration 

of the petition, EPA believed that it would be appropriate to extend the 500-ppm diesel 

transmix flexibility beyond 2014. EPA finalized a settlement agreement and this DFR 

and NPRM are in accord with the settlement agreement. Our analysis indicates that 

extending this flexibility beyond 2014 will have a neutral or net beneficial effect on 

overall emissions.

Yellow Marker Amendments

The yellow marker amendments address an oversight in the original nonroad 

diesel rulemaking. In that rulemaking, the regulations failed to incorporate provisions 

described in the rulemaking preamble. The preamble made clear that EPA intended to 

allow 500 ppm locomotive marine (LM) diesel fuel containing greater than 0.10 

milligrams per liter of Solvent Yellow 124 (SY124) time to transition out of the fuel 

distribution system. However, the regulations are not consistent with the preamble and 

did not provide this same allowance.

Specifically, the regulations as currently written do not provide any transition 

time for unmarked LM fuel delivered from a truck loading rack beginning June 1, 2012 to 

work its way through the fuel distribution system downstream of the truck loading rack. 

The yellow marker amendments will allow 500 ppm LM diesel fuel at any point in the 

fuel distribution and end use system to contain more than 0.10 milligrams per liter of SY 

124 through November 30, 2012. This regulatory change will allow marked LM diesel 

fuel to transition normally through the LM fuel distribution and use system. Today’s rule 

also amends the regulation to clarify the transition of the solvent yellow 124 marker out 

of heating oil beginning June 1, 2014. After December 1, 2014, EPA will no longer have 

any requirements with respect to the use of the SY 124 marker. 

C. Costs and Benefits

These three sets of amendments attempt to provide new opportunities for RIN 

generation under the RFS program and necessary flexibilities and transition periods for 

those affected by EPA’s transmix and marker requirements. Therefore, EPA believes 

that these amendments will impose no new direct costs or burdens on regulated entities

beyond the minimal costs associated with reporting and recordkeeping requirements. At 

the same time, EPA does not believe that any of these amendments will adversely impact 

emissions. 

II. Why is EPA Issuing a Direct Final Rule?

EPA is publishing this rule without a prior proposed rule because this may be 

viewed as a noncontroversial action that would not receive adverse comment. However, 

in the “Proposed Rules” section of today’s Federal Register, we are publishing a separate

document that will serve as the proposal to adopt the provisions in this direct final rule if

V. Amendments under the Renewable Fuel Standard Program

A. Amended Definition of Heating Oil

EPA is issuing a direct final rule to amend the definition of heating oil in 40 CFR 

§ 80.1401 in the renewable fuel standard (“RFS” or “RFS2”) program promulgated under

section 211(o) of the Clean Air Act (CAA).

2

This amendment will expand the scope of 

renewable fuels that can generate Renewable Identification Numbers (“RINs”) as home 

heating oil to include fuel oil that will be used to generate heat to warm buildings or other 

facilities where people live, work, recreate, or conduct other activities. This rule will

allow producers or importers of fuel oil that meets the amended definition of heating oil 

to generate RINs, provided that other requirements specified in the regulations are met. 

Fuel oils used to generate process heat, power, or other functions will not be approved for 

RIN generation under the amended definition of heating oil, as these fuels are not within 

the scope of “home heating oil” as that term is used in the Energy Independence and 

Security Act of 2007 (“EISA”), for the RFS program. The amendment will not modify or 

limit fuel included in the current definition of heating oil at 40 CFR § 80.2(ccc). 

The RFS program requires the production and use of renewable fuel to replace or 

reduce the quantity of fossil fuel present in transportation fuel. Under EPA’s RFS 

program this is accomplished by providing for the generation of RINs by producers or 

importers of qualified renewable fuel. RINs are transferred to the producers or importers 

of gasoline and diesel transportation fuel who then use the RINs to demonstrate 

compliance with their renewable fuel volume obligations. RINs also serve the function 

of credits under the RFS program. 

Congress provided that EPA could also establish provisions for the generation of 

credits by producers of certain renewable fuel that was not used in transportation fuel, 

called “additional renewable fuel.”3 Additional renewable fuel is defined as fuel that is

produced from renewable biomass and that is used to replace or reduce the quantity of 

fossil fuel present in home heating oil or jet fuel.4 In essence, additional renewable fuel 

has to meet all of the requirements applicable to qualify it as renewable fuel under the 

regulations, with the only difference being that it is blended into or is home heating oil or 

jet fuel. This does not change the volume requirements of the statute itself, however this 

can provide an important additional avenue for parties to generate RINs for use by

obligated parties, thus promoting the overall cost-effective production and use of 

renewable fuels. 

EPA addressed the provision for additional renewable fuels in the RFS2 

rulemaking, specifically addressing the category of “home heating oil.” EPA determined 

that this term was ambiguous, and defined it by incorporating the existing definition of 

heating oil at 40 CFR § 80.2(ccc). EPA stated that:

EISA uses the term “home heating oil” in the definition of “additional 

renewable fuel.” The statute does not clarify whether the term should be 

interpreted to refer only to heating oil actually used in homes, or to all fuel 

of a type that can be used in homes. We note that the term ‘home heating 

oil’ is typically used in industry in the latter manner, to refer to a type of 

fuel, rather than a particular use of it, and the term is typically used 

interchangeably in industry with heating oil, heating fuel, home heating 

fuel, and other terms depending on the region and market. We believe this 

broad interpretation based on typical industry usage best serves the goals 

and purposes of the statute. If EPA interpreted the term to apply only to 

heating oil actually used in homes, we would necessarily require tracking 

of individual gallons from production through ultimate [use] in homes in 

order to determine eligibility of the fuel for RINs. Given the fungible 

nature of the oil delivery market, this would likely be sufficiently difficult 

and potentially expensive so as to discourage the generation of RINs for 

renewable fuels used as home heating oil. This problem would be similar 

to that which arose under RFS1 for certain renewable fuels (in particular 

biodiesel) that were produced for the highway diesel market but were also 

 

as the types of land from which the biomass may be harvested.” Regulation of Fuels and Fuel Additives:

suitable for other markets such as heating oil and non-road applications 

where it was unclear at the time of fuel production (when RINs are 

typically generated under the RFS program) whether the fuel would 

ultimately be eligible to generate RINs. Congress eliminated the 

complexity with regards to non-road applications in RFS2 by making all 

fuels used in both motor vehicle and nonroad applications subject to the 

renewable fuel standard program. We believe it best to interpret the Act so 

as to also avoid this type of complexity in the heating oil context. Thus, 

under today’s regulations, RINs may be generated for renewable fuel used 

as “heating oil,” as defined in existing EPA regulations at §80.2(ccc). In 

addition to simplifying implementation and administration of the Act, this 

interpretation will best realize the intent of EISA to reduce or replace the 

use of fossil fuels.5 

The existing definition of heating oil at 40 CFR § 80.2(ccc) means “any #1, #2, or 

non-petroleum diesel blend that is sold for use in furnaces, boilers, stationary diesel 

engines, and similar applications and which is commonly or commercially known or sold 

as heating oil, fuel oil, or similar trade names, and that is not jet fuel, kerosene, or [Motor 

Vehicle, Non-Road, Locomotive and Marine (MVNRLM)] diesel fuel.” The existing 

definition of non-petroleum diesel at 40 CFR § 80.2(sss) means a diesel fuel that contains 

at least 80 percent mono-alkyl esters of long chain fatty acids derived from vegetable oils 

or animal fats. Thus, in order to generate RINs for home heating oil that is a nonpetroleum diesel blend, the fuel must contain at least 80 percent mono-alkyl esters of 

long chain fatty acids derived from vegetable oils or animal fats, as well as meeting all 

other requirements of the RFS2 regulations. Since the promulgation of the RFS2 final 

rule, we have received a number of requests from producers to consider expanding the 

scope of the home heating oil provision to include additional fuel oils that are produced 

from qualifying renewable biomass but do not meet the regulatory definition of heating 

oil because they are not #1 or #2 diesel and do not contain at least 80 percent mono-alkyl

esters. Parties raising this issue have suggested that limiting “home heating oil” to the 

fuel types defined in 40 CFR § 80.2(ccc) disqualifies certain types of renewable fuel oils 

that could be used for home heating and that this limitation does not align with our 

reasoning in the preamble to take a broad interpretation of the term “home heating oil” in 

CAA section 211(o). 

EPA has considered this issue further and is revising the definition of heating oil 

in the RFS2 program to expand the scope of fuels that can generate RINs as heating oil. 

EPA is revising the definition such that RINs also may be generated by renewable fuel 

that is fuel oil and is used to heat interior spaces of homes or buildings to control ambient 

climate for human comfort. This will not include fuel oils used to generate process heat, 

power, or other functions. The fuel oil must be used to generate heat to warm buildings 

or other facilities where people live, work, recreate, or conduct other activities. The fuel 

oil must only be used in heating applications, where the sole purpose of the fuel’s use is 

for heating and not for any other combined use such as process energy use. We are 

amending the existing definition of heating oil in 40 CFR § 80.1401 to include fuel oils 

that are used in this way. This is in addition to the fuel oils currently included in the 

definition of heating oil at 40 CFR § 80.2(ccc), and will not modify or limit the fuel 

included in the current definition.

EPA believes this expansion of the scope of the home heating oil provision is 

appropriate and authorized under CAA section 211(o). As EPA described in the RFS2 

final rule, Congress did not define the term “home heating oil,” and it does not have a 

fixed or definite commercial meaning. In the RFS2 final rulemaking, EPA focused on 

whether the provision was limited to heating oil actually used in homes. EPA noted that 
***EPA Response to OMB Comments (08/09/2012)***

EO12866_RFS Definition of Heating Oil_ 2060-AR44_DFR_20120425

Page 15 of 55

the term home heating oil is usually used in the industry to refer to one type of fuel, and 

not to a specific use for the fuel. Given this more general usage of the term, and the 

practical barriers that would have arisen if the term was defined as fuel actually used to 

heat homes, EPA defined the scope of home heating oil in a more specific fashion by

identifying those types of fuel oils that are typically used to heat homes. EPA determined 

this was a reasonable interpretation of an ambiguous statutory provision that simplified 

implementation and administration of the Act and promoted achievement of the goals of 

the RFS program. 

In the RFS2 rulemaking, EPA focused on the kinds of fuel oils that can be used to 

heat homes. The expansion of the definition adopted in this rulemaking will address two 

types of fuel oils not included in the current definition of heating oil. First, the amended

definition will include additional fuel oils that are actually used to heat homes, even if 

they do not meet the current definition of heating oil. This is clearly within the scope of 

the statutory provision for home heating oil.

Second, the amended definition will include fuel oils that are used to heat 

facilities other than homes to control ambient climate for human comfort. Under the 

current definition of heating oil, a fuel oil meets the definition based on its physical 

properties and its use in furnaces, boilers, stationary diesel engines, and similar 

applications, not whether it is actually used to heat a home. The basic decision made in 

the RFS2 final rulemaking was to allow RIN generation for the group of fuel oils that are 

typically used for home heating purposes. Under the current definition the relationship of

the fuel oil to heating homes is that the fuel oil is of the type that is typically used for and 

can be used for that purpose.6

In the amended definition, qualifying fuel oils will be used for heating places 

where people live, work, or recreate, and not just their homes. It focuses more on what is 

getting heated – people – and not where the people are located. EPA believes this is a 

reasonable interpretation of the phrase “home heating oil,” while recognizing that it is not 

an obvious interpretation. This interpretation recognizes the ambiguity of the phrase used 

by Congress, which is not defined and does not have a clear and definite commercial 

meaning. It gives reasonable meaning to the term home heating oil, by limiting the 

additional fuel oils to fuel oils when used for heating of facilities that people will occupy, 

and excluding fuel oils when used for other purposes such as generation of energy used in 

the manufacture of products. It also focuses on the aspect of home that is important here

– the heating of people – recognizing that EPA has already determined that fuel oil can be

included in the scope of home heating oil even if it is not actually used to heat a home. 

This interpretation will also promote the purposes of the EISA and the RFS program. It 

will promote the purposes of the EISA in that it will increase the production and use of 

renewable fuels by introducing new sources of fuel producers to the RFS program. It will 

specifically promote the RFS programmatic goals by facilitating the generation of RINs 

for renewable fuels that reduce emissions of greenhouse gases compared to fossil fuels. 

For example, EPA has received information from Envergent Technologies (alliance of 

Ensyn and UOP/Honeywell) that such an expanded definition of heating oil would result 

 

6

 This is different from other renewable fuels in the RFS program, which are defined in terms of their use 

as transportation fuel or jet fuel. See 40 CFR § 80.1401, definitions of “renewable fuel” and “transportation 

fuel.”

in nearly immediate production of 3.5 million gallons from their existing facilities, with 

an additional projected production of up to 45 million gallons per year within 24 months 

following regulatory action. Based on this information from Envergent Technologies, 

application of the expanded definition of heating oil to the entire industry would result in 

the production of many more million additional gallons of renewable fuel.

B. Lifecycle Greenhouse Gas Assessment of the Amended Definition of Heating Oil

EPA has also evaluated whether any revisions will need to be made to Table 1 to 

40 CFR § 80.1426 that lists the applicable D codes for each fuel pathway for use in 

generating RINs in the RFS2 regulations in light of the additional fuel oils included in the 

expanded definition of heating oil. As discussed below, EPA has determined that the 

applicable D code entries for heating oil in Table 1 to 40 CFR § 80.1426 will continue to 

be appropriate and will not need to be revised in light of the expanded definition of 

heating oil.

Under the RFS program, EPA must assess lifecycle greenhouse gas (GHG) 

emissions to determine which fuel pathways meet the GHG reduction thresholds for the 

four required renewable fuel categories. The RFS program requires a 20% reduction in 

lifecycle GHG emissions for conventional renewable fuel (except for grandfathered 

facilities and volumes), a 50% reduction for biomass-based diesel or advanced biofuel, 

and a 60% reduction for cellulosic biofuel. For the final RFS2 rule, EPA assessed the 

lifecycle greenhouse gas emissions of multiple renewable fuel pathways and classified 

pathways based on these GHG thresholds, as compared to the EISA statutory baseline.7 

 

7

See Table 1 to 40 CFR § 80.1426.

EO12866_RFS Definition of Heating Oil_ 2060-AR44_DFR_20120425

Page 18 of 55

In addition, EPA has added several pathways since the final rule was published. 

Expanding the definition of heating oil does not affect these prior analyses.

The fuel pathways consist of fuel type, feedstock, and production process 

requirements. GHG emissions are assessed at all points throughout the lifecycle 

pathway. For instance, emissions associated with sowing and harvesting of feedstocks 

and in the production, distribution and use of the renewable fuel are examples of what are 

accounted for in the GHG assessment. A full accounting of emissions is then compared 

with the petroleum baseline emissions for the transportation fuel being replaced. The 

lifecycle GHG emissions determination is one factor used to determine compliance with 

the regulations.

There are currently several fuel pathways that list heating oil as a fuel type with 

various types of feedstock and production processes used, qualifying the heating oil 

pathways as either biomass-based diesel, advanced, or cellulosic. The determinations for 

these different pathways were based on the current definition of heating oil. The 

pathways also include several types of distillate product including diesel fuel, jet fuel and 

heating oil. 

The lifecycle calculations and threshold determinations are based on the GHG 

emissions associated with production of the fuel and processing of the feedstock. 

Converting biomass feedstocks such as triglycerides (if oils are used as feedstock) or 

hemi-cellulose, cellulose, lignin, starches, etc. (if solid biomass feedstock is used) into 

heating oil products and can be accomplished through either a biochemical or 

thermochemical process converting those molecules into a fuel product. The existing 

heating oil pathways were based on the current definition of the fuel, and were based on a

Page 19 of 55

certain level of processing to produce #1, #2, or a non-petroleum diesel blend and the 

related energy use and GHG emissions that were part of the lifecycle determination for 

those fuel pathways.

The main difference between the current definition of heating oil, which refers to 

#1, #2, or a non-petroleum diesel blend, and the expanded definition adopted in this 

rulemaking is that the expanded definition will include heavier types of fuel oil with 

larger molecules. Based on the type of conversion process, producing these heavier fuel

oil products versus the #1, #2, or a non-petroleum diesel blend will affect the amount of 

energy used and therefore the GHG emissions from the process. There are two main 

paths for producing a fuel oil product from biomass. In one the biomass is converted into 

a biocrude which is further refined into lighter products. In this case producing a heavier 

fuel oil product will require less processing energy and have lower GHG emissions than 

converting the same feedstock into a #1, #2, or non-petroleum diesel blend. 

In the other type of process the compounds in the biomass are changed into a set 

of intermediary products, such as hydrogen (H) and carbon monoxide (CO).

8

 These 

compounds are then either catalytically or biochemically converted into the fuel product. 

In this case, the vast majority of the energy is associated with breaking down the 

feedstock into the set of intermediary compounds. The process used and the energy

needed for it does not vary based on the type of fuel that is then produced from these 

intermediary compounds. The type of fuel could affect the type of catalyst or biological 

process used to change the intermediary compounds into the fuel product, but based on 

 

8 This describes the Fischer-Tropsch process. Other processes rely on forming different sets of compounds 

from the biomass, and then producing the fuel product from the set of compounds.

this will

have no real impact on the energy used or the GHG emissions associated with converting 

the biomass into a different fuel product. 

Based on these considerations, EPA believes the GHG emissions associated with 

producing the fuel oil included in the expanded definition will be the same or lower than 

the GHG emissions associated with producing #1, #2, or non-petroleum diesel blend. 

Therefore, EPA believes the prior life cycle analysis for heating oil support applying the 

existing pathways for fuel oil in the RFS2 regulations to the expanded definition of 

heating oil. Once the regulatory change to the definition of “heating oil” is final, all of 

the pathways currently applicable to heating oil under Table 1 to 40 CFR § 80.1426 

would apply to the expanded definition of heating oil. 

C. Additional Registration, Reporting, Product Transfer Document, and 

Recordkeeping Requirements 

1. Additional Requirements for the Amended Definition of Heating Oil

An important issue to address is how to implement such an expanded definition. 

As EPA recognized in the RFS2 rulemaking, fuel oils end up being used in a variety of 

different uses, where the fuel producer may have little knowledge at the time of 

production as to eventual use of the fuel. This is especially the case where the fuel oil is 

distributed in a fungible distribution system. EPA addressed this in the RSF2 rulemaking 

by defining home heating oil as a type of fuel with certain characteristics, irrespective of 

where it was used. This approach avoided the need to track the fuel to its actual use, and

Page 21 of 55

including the characteristics of the fuel in its definition in 40 CFR § 80.1401, was 

adequate to retain a close tie to the concept underlying home heating oil. 

The expansion of the definition raises this same issue but in a more significant 

way. While the expansion of the definition includes some limited physical characteristics 

that fuels oils will need to meet in order to qualify for generating RINs, it does not 

provide sufficient specificity to differentiate between those fuels oils used to heat 

buildings for climate control for human comfort and those used to generate process heat 

or other purposes. Therefore, for eligible fuel oils other than those qualifying under the 

existing definition in 40 CFR § 80.2(ccc), EPA is requiring that the renewable fuel 

producer or importer have adequate documentation to demonstrate that the fuel oil 

volume for which RINs were generated was used to heat buildings for climate control for 

human comfort and meets the expanded definition of heating oil prior to generating RINs. 

EPA recognizes that under the current definition of heating oil no tracking or 

other documentation of end use is required, and some heating oils that meet the current 

definition could end up being used for other purposes. However, in all cases the heating

oil under the current definition has to have the physical or other characteristics that tie it 

to the type of fuel oil used to heat homes. In addition, because these fuel oils will qualify

to generate RINs under the RFS program, it will likely lead to their use for heating of 

buildings, and not for generation of process heat. For the fuel oils included in the 

expanded definition, the tie to home heating oil will not be the physical characteristics of 

the fuel oil but instead its actual usage for heating for the purposes of climate control for 

human comfort.

Page 22 of 55

In order to verify that the fuel oils are actually used to generate heat for climate 

control purposes, EPA is adopting the following registration, recordkeeping, product 

transfer document (PTD) and reporting requirements. These requirements will not apply

to fuels qualifying under the existing 40 CFR § 80.2(ccc) of the regulations. If RINs are 

generated for fuel oils under the expansion of the scope of home heating oil in today’s 

rule, and those fuel oils are designated for but not actually used to generate heat for 

climate control purposes, but for some other purpose, all parties involved in either the 

generation, assignment, transfer or use of that RIN, including the end user of that fuel oil, 

are subject to and liable for violations of the RFS2 regulations and the CAA.

a. Registration

For the purpose of registration, EPA is allowing the producer of the expanded fuel 

oil types to establish their facility’s baseline volume in the same manner as all other 

producers under the RFS program, e.g., based on the facility’s permitted capacity or 

actual peak capacity. Additionally though, we are requiring producers of the expanded 

fuel oil types to submit affidavits in support of their registration, including a statement 

that the fuel will be used for the purposes of heating interior spaces of homes or buildings 

to control ambient climate for human comfort, and no other purpose. We also require 

that producers submit secondary affidavits from the existing end users to verify that the 

fuel is actually being used for a qualifying purpose. We are also adopting new reporting, 

product transfer documents (PTD), and recordkeeping requirements discussed below that

will be used as a means for verification that the qualifying fuel is being used in an 

approved application. These requirements are necessary to assure confidence that the 

fuel used to generate RINs is actually used for a qualifying purpose because these types

Page 23 of 55

of fuel have not previously been used as heating oil, and are not readily identifiable by 

their physical characteristics. Without such safeguards, EPA could not be confident that 

the fuel is used as heating oil, and end users might not have adequate notice that the fuel 

must be used as heating oil. EPA believes these requirements will place a small burden 

on producers and end users, and greatly benefit the integrity of the program.

b. Reporting, Product Transfer Documents and Recordkeeping 

Requirements

For the purpose of continued verification after registration, EPA is adopting 

additional requirements for reporting in § 80.1451(b)(1)(ii)(T), PTDs in § 80.1453(d), 

and recordkeeping in 40 CFR § 80.1454(b), for the expanded fuel oil types.

The reporting, PTD, and recordkeeping requirements will help ensure that the 

expanded fuel oil types that are used to generate RINs are actually used in a qualifying 

application. For reporting, producers are required to file quarterly reports with EPA that 

identify certain information about the volume of fuel oil produced and used as heating 

oil. The additional reporting requirements stipulate that the producer of fuel oils submit 

affidavits to EPA reporting the total quantity of the fuel oils produced, the total quantity

of the fuel oils sold to end users, and the total quantity of fuel oils sold to end users for 

which RINs were generated. Additionally, affidavits from each end user must be 

obtained by the producer and reported to EPA, describing the total quantity of fuel oils 

received from the producer, the total amount of fuel oil used for qualifying purposes, the 

date the fuel oil was received from the producer, the blend level of the fuel oil, quantity

of assigned RINs received with the renewable fuel, and quantity of assigned RINs that

the end user separated from the renewable fuel, if applicable.

10 The additional product 

transfer document requirement associated with the expanded definition of heating oil is

that a PTD must be prepared and maintained between the fuel oil producer and the final 

end user for the legal transfer of title or custody of a specific volume of fuel oil that is 

designated for use, and is actually used, only for the purpose of heating interior spaces of 

buildings to control ambient climate for human comfort. This additional PTD 

requirement requires that the PTD used to transfer ownership or custody of the renewable 

fuel must contain the statement: “This volume of renewable fuel is designated and 

intended to be used to heat interior spaces of homes or buildings to control ambient 

climate for human comfort. Do NOT use for process heat or any other purpose, pursuant 

to 40 CFR § 80.1460(g).” EPA believes that this PTD requirement will help to ensure 

that each gallon of fuel oil that is transferred from the producer to the end user is used for 

qualifying purposes under the expanded definition of heating oil. If the fuel oil is sent to 

the end user, but the fuel oil is not actually used to generate heat for climate control 

purposes, but for some other non-qualifying purpose, then the RINs that were generated 

for that fuel oil must be immediately retired and reported under 40 CFR § 80.1451. The 

additional recordkeeping requirement is that producers are required to keep copies of the 

contracts which describe the fuel oil under contract with each end user. Consistent with 

existing regulations, producers are required to maintain all documents and records 

submitted for registration, reporting, and PTDs as part of the producer’s recordkeeping 

requirements. EPA believes the producer’s maintenance of these records will allow for

 

10 EPA does not expect that the expanded definition of home heating oil will result in an obligation on 

home owners or small businesses. Based on our analysis of the market, qualifying fuel oil is expected to be 

used in large industrial settings or apartment buildings, not in individual homes. Therefore, EPA 

anticipates that the information it is requiring would be readily available and producible by these entities.

continued tracking and verification that the end use of the fuel oil is in compliance with 

the expanded definition of heating oil. 

D. Additional Requirement for RIN Generation

We are also amending the regulatory text that describes the general requirements 

for how RINs are generated and assigned to batches of renewable fuel by renewable fuel 

producers and importers. This will explicitly clarify a requirement that always existed: 

that producers and importer of renewable fuel who generate RINs must comply with the 

registration requirements of 40 CFR § 80.1450, the reporting requirements of 40 CFR §

80.1451, the recordkeeping requirements of 40 CFR § 80.1454, and all other applicable 

regulations of this subpart M. This is a generally applicable requirement – not specific to 

fuel meeting the definition of home heating oil. See amended section 80.1426(a)(1)(iii).

VI. Amendments Related to Transmix

The final regulations for the nonroad diesel program were published in the 

Federal Register on June 24, 2004.

11 The provisions in the nonroad diesel rule related to 

transmix processors were modified by the Category 3 Marine diesel final rule that was 

published on April 30, 2010.

12 This action amends the requirements for diesel fuel 

produced by transmix processors. Below is a table listing the provisions that we are 

amending. The following sections provide a discussion of these amendments.

A. Extension of the Diesel Transmix Provisions Outside of the Northeast 

Mid-Atlantic Area and Alaska Beyond 2014

Batches of different fuel products commonly abut each other as they are shipped 

in sequence by pipeline. When the mixture between two adjacent products is not 

compatible with either product, it is removed from the pipeline and segregated as 

transmix. Transmix typically is gathered for reprocessing at the end of the fuel 

distribution system far from a refinery. In addition to the long transportation distances to 

return transmix to a refinery for reprocessing, incorporating transmix into a refinery’s 

feed also presents technical and logistical refining process challenges that typically make 

refinery reprocessing an unattractive option. Thus, transmix processers provide a 

valuable service in maintaining an efficient fuel distribution system. Transmix 

processing facilities handle very low volumes of fuel compared to a refinery and hence 

are limited to the use of a simple distillation tower and additional blendstocks to

manufacture finished fuels. There is currently no desulfurization equipment which has 

been demonstrated to be suitable for application at a transmix processor facility. The cost 

of installing and operating a currently available desulfurization unit is too high in relation 

to the small volume of distillate fuel produced at transmix processing facilities. Some 

products shipped by pipeline such as jet fuel and heating oil are subject to relatively high 

sulfur specifications (e.g., maximum 3,000 ppm for jet fuel). The presence of such high 

sulfur products in multi-product pipelines and consequently in transmix constrains the 

ability of transmix processors to produce a low sulfur distillate product. 

The engine emission standards finalized in the nonroad diesel rulemaking for 

new nonroad, locomotive, and Category 1 & 2 (C1 & C2) marine engines necessitates the 

use of sulfur-sensitive emissions control equipment which requires 15 ppm sulfur diesel 

fuel to function properly.

13

 Accordingly, the nonroad rule required that nonroad, 

locomotive and marine (NRLM) diesel fuel must meet a 15 ppm sulfur standard in 

parallel with the introduction of new sulfur-sensitive emission control technology to 

NRLM equipment. Beginning June 1, 2014, the nonroad diesel rule required that all 

NRLM diesel fuel produced by refiners and importers must meet a 15 ppm sulfur 

standard. The nonroad diesel rule included special provisions to allow the continued use 

of 500 ppm sulfur locomotive and marine (LM) diesel fuel produced from transmix 

beyond 2014 in older technology engines as long as such engines remained in the in-use 

fleet. These provisions along with other now expired flexibilities in the diesel program 

were designed to minimize and postpone the impacts on transmix processors of 

transitioning to a condition where all highway, nonroad, locomotive, and marine diesel

engines can only operate on 15 ppm diesel fuel.14 The 500 ppm LM diesel transmix 

provisions were limited to areas outside of the Northeast Mid-Atlantic Area (NEMA) and 

Alaska because it was judged that the heating oil market in these areas would provide a 

sufficient outlet for transmix distillate in these areas.15 Excluding the NEMA area and 

Alaska also allowed us to exempt the NEMA area and Alaska from the fuel marker 

provisions that are a part of the compliance assurance regime. The continuation of the 

500 ppm LM diesel transmix provisions beyond 2014 (finalized in the nonroad rule) was 

supported by ongoing recordkeeping, reporting, and fuel marker provisions that were 

established to facilitate enforcement during the phase in of the diesel sulfur program.16

In the development of the proposed requirements for Category 3 (C3) marine 

engines, EPA worked with industry to evaluate how the enforcement provisions for the 

new 1,000-ppm C3 marine diesel fuel to be introduced in June of 2014 could be 

incorporated into existing diesel program provisions.17 Our assessment based on input 

from industry at the time indicated that incorporating the new C3 marine fuel into the 

 

14 As discussed in the original nonroad diesel rulemaking, as LM equipment is retired from service, the 

market for 500 ppm LM will gradually diminish and eventually disappear. Given the long lifetime of LM 

equipment (in many cases 40 years or more), we anticipate that a market for 500 ppm LM will remain for a 

significant amount of time. This phase-out time will also allow transmix processors to transition to their 

>15ppm sulfur distillate product to other markets (C3 marine, heating oil, process heat). It may also allow

sufficient time for the introduction of desulfurization equipment that is suitable for use at transmix 

processing facilities.

15 The NEMA area is defined in 40 CFR § 80.510(g)(1) as follows: (1) Northeast/Mid-Atlantic Area, which 

includes the following States and counties, through May 31, 2014: North Carolina, Virginia, Maryland, 

Delaware, New Jersey, Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, Maine, 

Washington DC, New York (except for the counties of Chautauqua, Cattaraugus, and Allegany), 

Pennsylvania (except for the counties of Erie, Warren, McKean, Potter, Cameron, Elk, Jefferson, Clarion, 

Forest, Venango, Mercer, Crawford, Lawrence, Beaver, Washington, and Greene), and the eight easternmost counties of West Virginia (Jefferson, Berkeley, Morgan, Hampshire, Mineral, Hardy, Grant, and 

Pendleton).

16 This included the now-completed phase-in of 15 ppm highway diesel fuel and 15 ppm nonroad diesel 

fuel as well as the phase-out of the small refiner and credits provisions for LM diesel fuel that will be 

completed in 2014.

diesel program enforcement mechanisms while preserving the 500 ppm diesel transmix 

flexibility could not be accomplished without retaining significant existing burdens and 

introducing new burdens on a broad number of regulated parties. We also concluded that 

the new C3 marine diesel market would provide a sufficient outlet for transmix 

processors distillate product in place of the 500 ppm LM diesel market. Thus, we 

believed the 500 ppm LM diesel transmix flexibility would no longer be needed after 

2014. Hence, we requested comment on whether we should eliminate the 500 ppm LM

transmix provisions in parallel with the implementation of the C3 marine diesel sulfur 

requirement. This approach allowed for a significant reduction in the regulatory burden 

on a large number of industry stakeholders through the retirement of the diesel program’s 

designate-and-track and fuel marker requirements. All of the comments that we received 

on the proposed rule were supportive of the approach. Consequently, we finalized the 

approach in the C3 marine final rule that was published on April 30, 2010.18

EPA received a petition from a group of transmix processors on June 29, 2010,

requesting that the Agency reconsider and reverse the 2014 sunset date for the 500 ppm

LM transmix flexibility.

finalized. The petitioners also stated that they believe that the C3 marine market would 

not be a viable outlet for their distillate product given the increased distribution costs 

compared to the 500 ppm LM market. Based on the additional input that we received 

from transmix processors and other stakeholders in the fuel distribution system during 

our consideration of the petition, EPA believes that while the increased costs for 

transportation of transmix distillate product could be accommodated, there is no 

compelling reason not to extend the 500 ppm diesel transmix flexibility beyond 2014 if 

such costs can be avoided or deferred without affecting the benefits from the diesel sulfur 

program. A settlement agreement has been finalized between EPA and the petitioners 

under which EPA would propose regulatory changes to reintroduce the 500 ppm LM

transmix diesel flexibility for legacy LM equipment.21 The amendments to the diesel 

transmix provisions contained in today’s action are in accord with the settlement 

agreement.

Our analysis indicates that extending the 500 ppm LM flexibility beyond 2014 

would have a neutral or net beneficial effect on overall vehicle emissions. The use of 500 

ppm LM from transmix would be limited to older technology engines that do not possess 

sulfur-sensitive emissions control technology. We believe that the 500 ppm LM

segregation and other associated requirements would prevent misfueling of sulfursensitive engines.

To evaluate the environmental consequences of extending the diesel transmix 

provisions, we compared the potential increase in sulfate particulate matter (PM) from 

the use of 500 ppm LM from transmix in older engines to the additional transportation

emissions associated with shipment to the Category 3 (C3) marine market which might 

be deferred by allowing continued access to the 500 ppm LM market. Markets for 

locomotive and marine diesel tend to be nearer to transmix processing facilities than 

markets for C3 marine diesel. Therefore, extending the diesel transmix provisions would 

result in a reduction in nitrogen oxides (NOX), volatile organic compounds (VOCs), 

carbon monoxide (CO), as well as PM emissions that would otherwise be associated with 

transporting transmix distillate product to the more distant C3 market.

Although some batches of transmix distillate product may approach the 500 ppm 

sulfur limit, we estimate that the average sulfur content of transmix distillate product 

would be no more than 300 ppm.22 We estimate that approximately 500 million gallons 

of distillate fuel per year is produced from transmix.23 Assuming that all of the transmix 

distillate product would be used as 500 ppm LM in older engines, we estimate that an 

additional 70 tons of sulfate PM would be produced annually compared to the use of 15 

ppm diesel fuel.24 We believe that a substantial fraction of transmix distillate product 

would be used as heating oil and C3 diesel fuel regardless of whether the diesel transmix 

provisions are extended. Also, as the older LM engines are retired from service, the size 

of the potential 500 ppm LM market will diminish until all LM engines must use 15 ppm 

diesel fuel. Therefore, assuming that all transmix distillate product would be used as 500 

ppm LM provides an upper bound estimate of the potential impact on PM emissions.

 

22 This is based on our review of data on the sulfur levels of transmix distillate product from various 

transmix processors. 

23 Based on information provided by transmix processors, we estimate that approximately 750 million 

gallons per year of transmix is produced annually and that 2/3 of the transmix-derived product is distillate 

fuel and 1/3 is gasoline. 

24 Sulfate PM was converted to PM2.5 to allow a comparison with PM2.5 from increased fuel transport 

emissions.

EO12866_RFS Definition of Heating Oil_ 2060-AR44_DFR_20120425

Page 32 of 55

We estimate on average that transmix processors would need to ship their transmix 

distillate product an additional 150 miles by tank truck to reach the C3 Emission Control 

Area (ECA) marine market as compared to the 500 ppm LM market.25 This would result 

in an additional 80 tons of PM emissions annually. Thus, the PM emissions associated 

with transport to the C3 marine market are roughly equal to the increased sulfate PM 

emissions associated with the continued use of 500 ppm LM. We estimate that the 

increased transport distances could also result in an additional 2,200 tons of NOX, 220 

tons of VOC, and 650 tons of CO annually. Based on the above discussion, we believe 

that the extension of the 500 ppm LM provisions beyond 2014 outside the NEMA area 

and Alaska would have a neutral or net positive environmental impact. 

The extension of the 500 ppm LM transmix flexibility would defer additional 

transportation costs and provide a lower-cost fuel for use in older LM engines for many 

years to come given that the useful life of LM engines can exceed 40 years.

26

 Therefore, 

extending this flexibility would reduce the overall burden on industry of compliance with 

EPA’s diesel sulfur program. Providing additional time for transmix processors to 

evaluate how the C3 ECA marine market will develop after 2014 would also facilitate a 

smoother transition for transmix processors from the 500 ppm LM market as it gradually

disappears due to fleet turnover. 

B. Revised Diesel Transmix Provisions

Industry stakeholders suggested alternative enforcement mechanisms to support 

the extended flexibility which would not necessitate reinstating and expanding the 

 

25 There is no ability to ship transmix distillate product to the C3 marine diesel market by pipeline.

26 In the 2011 edition of “Railroad Facts,” the Association of American Railroads reported that in 2010 

approximately 35% of the locomotive fleet was at least 21 years old.
***EPA Response to OMB Comments (08/09/2012)***

***E.O. 12866 Review – Draft (4/25/2012) – Do Not Cite, Quote or Release During Review***

Page 33 of 55

designate-and-track and fuel marker provisions that were retired by the C3 marine final 

rule. Reinstatement and expansion of these provisions would likely place an 

unacceptable burden on a large number of stakeholders, most of whom would not handle 

500 ppm LM. The suggested alternative enforcement mechanism would impose minimal 

additional reporting and recordkeeping burdens only on the parties that produce, handle, 

and use 500 ppm LM. We believe that this alternative enforcement approach would meet 

the Agency’s goals of ensuring that the pool of 500 ppm LM is limited to transmix 

distillate and that 500 ppm LM is not used in sulfur-sensitive emissions control 

equipment. 

The compliance assurance provisions that we are using to support the extension of 

the diesel transmix flexibility are similar to those that were used to support the small 

refiner flexibilities in Alaska during the phase-in of EPA’s diesel sulfur program.27 In 

addition to registering as a refiner and certifying that each batch of fuel complies with the 

fuel quality requirements for 500 ppm LM diesel fuel, producers of 500 ppm transmix 

distillate product would be required to submit a compliance plan for approval by EPA. 

This compliance plan would provide details on how the 500 ppm LM would be 

segregated through to the ultimate consumer and its use limited to the legacy LM fleet. 

The plan would be required to identify the entities that would handle the fuel and the

means of segregation. We believe that it is appropriate to limit the number of entities that 

would be allowed to handle the fuel between the producer and the ultimate consumer in 

order to facilitate EPA’s compliance assurance activities.28 Based on conversations with 

transmix processors, we believe that specifying that no more than 4 separate entities 

 

27 See 40 CFR § 80.554(a)(4). 

28 An entity is defined as any company that takes custody of 500 ppm LM diesel fuel.

EO12866_RFS Definition of Heating Oil_ 2060-AR44_DFR_20120425

Page 34 of 55

handle the fuel between the producer and the ultimate consumer would not hinder the 

ability to distribute the fuel.29 The plan would need to identify the ultimate consumers 

and include information on how the product would be prevented from being used in 

sulfur-sensitive equipment. 

We understand that some transmix processors currently rely on shipment by 

pipeline to reach the 500 ppm locomotive diesel market.

30

 As a result, the regulations

allow 500 ppm LM to be shipped by pipeline provided that it does not come into contact 

with distillate products that have a sulfur content greater than 15 ppm. The compliance 

plan would need to include information from the pipeline operator regarding how this 

segregation would be maintained. Discussions with transmix processors indicate that this 

requirement would not limit their ability to ship 500 ppm LM by pipeline. If 500 ppm

LM was shipped by pipeline abutting 15 ppm diesel, the volume of 500 ppm LM

delivered would likely be slightly greater than that which was introduced into the pipeline 

as a consequence of cutting the pipeline interface between the two fuel batches into the 

500 ppm LM batch. This small increase in 500 ppm LM volume would be acceptable. 

To provide an additional safeguard to ensure that volume of 500 ppm LM diesel 

fuel does not swell inappropriately, the volume increase during any single pipeline 

shipment must be limited to 2 volume percent or less. This limitation on volume swell to 

2 volume percent or less is consistent with the limitation in 40 CFR § 80.599 (b)(5) 

 

29 In most cases, fewer entities would take custody of the product. In many cases, only a single entity (a 

tank truck operator) would be in the distribution chain between the transmix processor and the ultimate 

consumer. However, we understand that as many as 4 separate entities may handle the product between the 

producer and ultimate consumer if it is shipped by pipeline: the tank truck operator to ship the product from 

the producer to the pipeline, the pipeline operator, the product terminal that receives the fuel from the 

pipeline, and another tank truck operator to ship the product to the ultimate consumer from the terminal. 

30 500 ppm LM diesel fuel is shipped by a short dedicated pipeline from a product terminal to a locomotive 

refueling facility.

regarding the allowed swell in volume during the shipment of highway diesel fuel for the 

purposes of the determination of compliance with the now expired volume balance 

requirements under 40 CFR § 80.598(b)(9)(vii)(B). Industry did not object to this 

requirement, and therefore, we believe that limiting the volume swell of 500 ppm LM 

diesel fuel during shipment by pipeline to 2 volume percent or less should provide 

sufficient flexibility. 

Product transfer documents (PTDs) for 500 ppm LM diesel are required to 

indicate that the fuel must be distributed in compliance with the approved compliance 

assurance plan. Entities in the distribution chain for 500 ppm LM diesel fuel are required 

to keep records on the volumes of the 500 ppm that they receive from and deliver to each 

other entity. Based on input from fuel distributors, keeping these records will be a 

minimal additional burden, as discussed in section VIII.B. Such entities are also required 

to keep records on how the fuel was transported and segregated. We would typically 

expect that the volumes of 500 ppm LM delivered would be equal to or less than those 

received unless shipment by pipeline occurred. Some minimal increase in 500 ppm LM

volume would be acceptable due to differences in temperature between when the shipped 

and received volumes were measured and interface cuts during shipment by pipeline. 

Entities that handle 500 ppm LM are required to calculate a balance of 500 ppm LM

received versus delivered/used on an annual basis. If the volume of fuel 

delivered/dispensed is greater than that received, EPA would expect that the records 

would indicate the cause. If an entity’s evaluation of their receipts and deliveries of 500 

ppm LM fuel indicated noncompliance with the product segregation requirements, the 

custodian would be required to notify EPA. All entities in the 500 ppm LM distribution

chain are required to maintain the specified records for 5 years and provide them to EPA 

upon request.

VII. Amendments Related to the Marker Requirements for Locomotive and 

Marine Fuel 

Today’s rule amends the regulatory provisions regarding the transition in the fuel 

marker requirements for 500 ppm LM diesel fuel in 2012 to address an oversight in the 

original rulemaking where the regulations failed to incorporate provisions described in 

the rulemaking preamble. Today’s rule also amends the regulatory provisions regarding 

the transition in the fuel marker requirements for heating oil in 2014 to provide improved 

clarity. 

The preamble in the nonroad diesel final rule stated that EPA intended to allow 

500 ppm LM diesel fuel containing greater than 0.10 milligrams per liter of solvent 

yellow 124 (SY124) to be present at any location in the fuel distribution system (up to 

and including retail and wholesale-purchaser-consumer storage tanks) until September 

30, 2012.

31

 Although it was not explicitly stated in the preamble, it was implied that 

additional time would be allowed for marked 500 ppm LM to transition from the fuel 

tanks connected to locomotive and marine engines, consistent with the approach taken 

regarding the implementation of more stringent diesel fuel sulfur standards. However, 

the nonroad diesel regulations are not consistent with the preamble and do not provide the

allowance for marked 500 ppm LM diesel fuel to transition from fuel distribution and 

end-user tanks. 40 CFR § 80.510(e) requires that all 500 ppm LM diesel fuel delivered 

from a truck loading rack located outside of the Northeast Mid-Atlantic (NEMA) area 

 

31 “Control of Emissions for Air Pollution From Nonroad Diesel Engines and Fuel; Final Rule,” Section 

V.C.1.c., “The Period From June 1, 2012 Through May 31, 2014, 69 FR 39083, 39084 (June 29, 2004).

***E.O. 12866 Review – Draft (4/25/2012) – Do Not Cite, Quote or Release During Review***

EO12866_RFS Definition of Heating Oil_ 2060-AR44_DFR_20120425

Page 37 of 55

and Alaska must contain at least 6 mg/liter of SY124 through May 31, 2012. However, 

the regulatory text at 40 CFR 80.510(f) requires that beginning June 1, 2012, any diesel 

fuel that contains 0.10 mg/liter of SY124 must be designated as heating oil. Thus, the 

regulations as currently written do not provide any transition time for marked LM fuel 

that is present the distribution system as of May 31, 2012 to work its way through the fuel 

distribution system downstream of the truck loading rack and through the tanks 

connected to locomotive and marine engines. 

A number of locomotive and marine wholesale purchaser-consumers have taken 

custody of marked 500 ppm LM diesel fuel that they will not be able to consume prior to 

June 1, 2012. A number of fuel suppliers also have inventories of 500 ppm LM diesel 

fuel on hand that they may not be able to sell to LM diesel fuel users because such users 

are concerned about clearing their tanks of marked LM diesel fuel by June 1, 2012. This 

new rule allows marked 500 ppm LM diesel fuel to transition normally through the fuel 

distribution and use system, consistent with the original intent of the nonroad diesel rule 

preamble. Today’s rule allows 500 ppm LM diesel fuel at any point in the fuel 

distribution and end use system to contain more than 0.10 milligrams per liter of SY 124 

through November 30, 2012. 

We are implementing a single transition date applicable at all points in the fuel 

distribution and use system rather than a separate date applicable through retail and 

wholesale-purchaser-consumer (WPC) facilities and another date applicable at all 

locations including the tanks attached to locomotive and marine equipment because we 

believe that a stepped compliance schedule is not necessary and a single transition date 

provides the most flexibility for regulated parties. We expect that the marker will

Page 38 of 55

typically transition out of retailer and WPC LM diesel storage tanks well in advance of 

November 30, 2012. We further expect that users of LM diesel fuel can coordinate with 

retail and WPC facilities regarding deliveries of marked 500 ppm LM diesel fuel to 

ensure that the fuel in storage tanks attached to LM equipment is in compliance by 

November 30, 2012. 

Today’s rule also amends the regulation to clarify the transition of the solvent 

yellow 124 marker out of heating oil beginning June 1, 2014. Specifically, today’s rule 

amends the regulations to clarify that after December 1, 2014, EPA will no longer have 

any requirements with respect to the use of the solvent yellow 124 marker. This is 

consistent with the intent expressed in our original nonroad diesel fuel rulemaking. We 

do not believe these changes will adversely impact emissions.

VIII. Statutory and Executive Order Reviews 

A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: 

Improving Regulation and Regulatory Review

Under Executive Order 12866 (58 CFR § 51735 (October 4, 1993), this action is a 

“significant regulatory action.” Accordingly, 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 

and direct final rule 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 (ICR) document prepared by EPA related to the amended

heating oil definition has been assigned EPA ICR number 2462.01 and the ICR document 

prepared by EPA for diesel fuel produced by transmix producers has been assigned EPA 

ICR number 2463.01. Supporting statements for these proposed ICRs have been placed 

in the docket. The proposed information collections are described in the following 

paragraphs. 

This action contains recordkeeping and reporting (registration and product 

transfer documentation) that may affect parties who produce or import renewable fuels 

subject to the revised definition of heating oil. EPA expects that very few parties will be 

subject to additional recordkeeping and reporting. We estimate that up to 11 parties (i.e., 

RIN generators, consisting of up to 10 producers and one importer) may be subject to the 

proposed information collection over the next several years.

32

 We estimate an annual 

reporting burden of 21 hours per respondent and an annual recordkeeping burden of 24 

hours, yielding a total per respondent burden of 45 hours.33 Burden means the total time, 

effort, or financial resources expended by 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 systems 

for the purpose of collecting, validating, and verifying information, processing and 

maintaining information, and disclosing and providing information; adjust the existing 

ways to comply with any previously applicable instructions and requirements; train 

personnel to be able to respond to a collection of information; search data sources; 

 

32 We project that the number of effected parties will remain essentially constant over time.

33 This includes the time to train staff, formulate and transmit responses, and other miscellaneous 

compliance related activities.

complete and review the collection of information; and transit or otherwise disclose the 

information. Burden is as defined at 5 CFR § 1320.3(b). 

This action also contains provisions related to diesel fuel that is produced by

transmix processors. We have proposed reporting requirements that would apply to 

transmix processors (all of whom are refiners) and other parties (such as carriers or 

distributors) in the distribution chain who handle diesel fuel produced by transmix 

producers. The collected data will permit EPA to: (1) Process compliance plans from 

transmix producers; and (2) Ensure that diesel fuel made from transmix meets the 

standards required under the regulations at 40 CFR Part 80, and that the associated 

benefits to human health and the environment are realized. We estimate that 25 transmix 

processors and 150 other parties may be subject to the proposed information collection.34 

We estimate an annual reporting burden of 28 hours per transmix processor (respondent) 

and 8 hours per other party (respondent); considering all respondents (transmix producers 

and other parties) who would be subject to the proposed information collection, the 

annual reporting burden, per respondent, would be 11 hours. Burden means the total 

time, effort, or financial resources expended by 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 systems 

for the purpose of collecting, validating, and verifying information, processing and 

maintaining information, and disclosing and providing information; adjust the existing 

ways to comply with any previously applicable instructions and requirements; train 

 

34 This is based on current transmix production. Although the total volume of transmix produced in the fuel 

distribution system may decline in parallel with the projected decrease in overall petroleum-based fuel use, 

we anticipate that the number of transmix processors will remain essentially constant since their number is 

dependent on the configuration of the petroleum-based fuel distribution system.

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). 

The amendments to the fuel marker requirements for locomotive and marine 

diesel fuel in today’s rule do not contain any new recordkeeping and reporting 

requirements.

An agency may not conduct or sponsor, and a person is not required to respond to, 

a collection of information unless it displays a currently valid OMB control number. The 

OMB control numbers for EPA’s regulations 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 rule, which includes the ICRs 

described above, under Docket ID number EPA-HQ-OAR-2012-0223. Submit any

comments related to the ICR to EPA and OMB. See the ADDRESSES section at the 

beginning of this notice for where to submit comments to EPA. Send 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 ICR between 30 and 60 days after 

[Insert date of publication in the Federal Register.], a comment to OMB is best 

assured of having its full effect if OMB receives it by [Insert date 30 days after

The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a 

regulatory flexibility analysis of any rule subject to notice and comment rulemaking 

requirements under the Administrative Procedure Act or any other statute unless the 

agency certifies that the rule will not have a significant economic impact on a substantial 

number of small entities. Small entities include small businesses, small organizations, 

and small governmental jurisdictions.

For purposes of assessing the impacts of today’s rule on small entities, small 

entity is defined as: (1) A small business as defined by the Small Business 

Administration’s (SBA) regulations at 13 CFR § 121.201; (2) a small governmental 

jurisdiction that is a government of a city, county, town, school district or special district 

with a population of less than 50,000; and (3) a small organization that is any not-forprofit enterprise which is independently owned and operated and is not dominant in its 

field.

After considering the economic impacts of this action on small entities, I certify

that this action will not have a significant economic impact on a substantial number of 

small entities. This final rule will not impose any new requirements on small entities. 

The amendments to the diesel transmix provisions would lessen the regulatory burden on 

all affected transmix processors and provide a source of lower cost locomotive and 

marine diesel fuel to consumers. The relatively minor corrections and modifications this 

rule do not impact small entities.

private sector in any one year. We have determined that this action will not result in 

expenditures of $100 million or more for the above parties and thus, this rule is not 

subject to the requirements of sections 202 or 205 of UMRA.

This rule is also not subject to the requirements of section 203 of UMRA because 

it contains no regulatory requirements that might significantly or uniquely affect small 

governments. It only applies to gasoline, diesel, and renewable fuel producers, importers, 

distributors and marketers and makes relatively minor corrections and modifications to 

the RFS2 and diesel sulfur regulations.

E. Executive Order 13132 (Federalism) 

This action does not have federalism implications. It will not have substantial 

direct effects on the States, on the relationship between the national government and the 

States, or on the distribution of power and responsibilities among the various levels of 

government, as specified in Executive Order 13132. This action only applies to gasoline, 

diesel, and renewable fuel producers, importers, distributors and marketers and makes 

relatively minor corrections and modifications to the RFS2 and diesel sulfur regulations. 

Thus, Executive Order 13132 does not apply to this action.

F. Executive Order 13175 (Consultation and Coordination With Indian Tribal 

Governments)

This rule does not have tribal implications, as specified in Executive Order 13175 

(65 FR 67249 (November 9, 2000)). It applies to gasoline, diesel, and renewable fuel 

producers, importers, distributors and marketers. This action makes relatively minor 

corrections and modifications to the RFS2 and diesel sulfur regulations, and does not

impose any enforceable duties on communities of Indian tribal governments. Thus, 

Executive Order 13175 does not apply to this action. 

G. Executive Order 13045: Protection of Children from Environmental Health Risks and 

Safety Risks

EPA interprets EO 13045 (62 FR 19885 (April 23, 1997)) as applying only to 

those regulatory actions that concern health or safety risks, such that the analysis required 

under section 5–501 of the 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 safety risks.

H. Executive Order 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 significant 

adverse effect on the supply, distribution, or use of energy. We have concluded that this 

rule is not likely to have adverse energy effects because we do not anticipate adverse 

energy effects related to the additional generation of RINs for home heating oil or the 

reduced regulatory burden for transmix processors. This rule will facilitate the use of 500 

ppm sulfur locomotive and marine (LM) diesel fuel, which contains the SY 124 marker 

that is already in the fuel distribution and use system consistent with EPA’s original 

intent. Today’s action will avoid the potential need to remove marked 500 ppm LM

diesel fuel from the system for reprocessing, and the associated increased costs and 

potential disruption to the supply of LM diesel fuel.

Page 45 of 55

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 

(‘‘NTTAA’’), Public Law 104–113, 12(d) (15 U.S.C. § 272 note) directs EPA to use 

voluntary consensus standards in its regulatory activities unless to do so will be 

inconsistent with applicable law or otherwise impractical. Voluntary consensus standards 

are technical standards (e.g., materials specifications, test methods, sampling procedures, 

and business practices) that are developed or adopted by voluntary consensus standards 

bodies. NTTAA directs EPA to provide Congress, through OMB, explanations when the 

Agency decides not to use available and applicable voluntary consensus standards.

This action does not involve technical standards. Therefore, EPA did not consider 

the use of any voluntary consensus standards.

J. Executive Order 12898: Federal Actions To Address Environmental Justice in 

Minority Populations and Low-Income Populations 

Executive Order (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.

EPA has determined that this rule will not have disproportionately high and 

adverse human health or environmental effects on minority or low-income populations 

because it does not affect the level of protection provided to human health or the 

environment. These amendments will not relax the control measures on sources regulated 

by the RFS regulations and therefore will not cause emissions increases from these

sources. We have determined that proposed amendments to the diesel transmix 

provisions and marker provisions for locomotive and marine diesel fuel under the diesel 

sulfur program would have a neutral or positive impact on diesel vehicle emissions.35 

K. Congressional Review Act

The Congressional Review Act, 5 U.S.C. § 801 et. seq., as added by the Small Business 

Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may

take effect, the agency promulgating the rule must submit a rule report, which includes a

copy of the rule, to each House of the Congress and to the Comptroller General of the 

United States. EPA will submit a report containing this rule and other required 

information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller 

General of the United States prior to publication of the rule in the Federal Register. A 

major rule cannot take effect until 60 days after it is published in the Federal Register. 

This action is not a ‘‘major rule’’ as defined by 5 U.S.C. § 804(2).

IX. Statutory Provisions and Legal Authority 

Statutory authority for the rule finalized today can be found in section 211 of the 

Clean Air Act, 42 U.S.C. § 7545. Additional support for the procedural and compliance 

related aspects of today’s rule, including the recordkeeping requirements, come from 

sections 114, 208, and 301(a) of the Clean Air Act, 42 U.S.C. §§ 7414, 7542, and 

7601(a).

3. Section 80.511 is amended by revising paragraphs (b)(4) and (b)(10) to read as 

follows:

§ 80.511 What are the per-gallon and marker requirements that apply to 

NRLM diesel fuel, ECA marine fuel, and heating oil downstream of 

the refiner or importer?

* * * * *

(b) * * *

(4) Except as provided in paragraphs (b)(5) through (8) of this section, the 

per-gallon sulfur standard of §80.510(c) shall apply to all NRLM diesel 

fuel beginning August 1, 2014 for all downstream locations other than 

retail outlets or wholesale purchaser-consumer facilities, shall apply to all 

NRLM diesel fuel beginning October 1, 2014 for retail outlets and 

wholesale purchaser-consumer facilities, and shall apply to all NRLM 

diesel fuel beginning December 1, 2014 for all locations. This paragraph 

(b)(4) does not apply to LM diesel fuel produced from transmix or 

interface fuel that is sold or intended for sale in areas other than those 

listed in §80.510(g)(1) or (g)(2), as provided by §80.513(f).

* * * * *

(10) For the purposes of this subpart, on any occasion where a distributor 

directly dispenses fuel into vehicles or equipment from a mobile facility

such as a tanker truck, the distributor shall be treated as a retailer, and the 

mobile facility shall be treated as a retail outlet.

4. Section 80.513 is amended as follows:

a. By revising the section heading.

b. By revising the introductory text.

c. By revising paragraph (e).

d. By adding a new paragraph (f).

§ 80.513 What provisions apply to facilities that process transmix?

For purposes of this section, transmix means a mixture of finished fuels, such as pipeline 

interface, that no longer meets the specifications for a fuel that can be used or sold 

without further processing. This section applies to refineries (or other facilities) that 

produce diesel fuel from transmix by distillation or other refining processes but do not 

produce diesel fuel by processing crude oil. This section only applies to the volume of 

diesel fuel produced by such a processor using these processes, and does not apply to any 

diesel fuel produced by the blending of blendstocks. For the purposes of this section, 

pipeline interface means the mixture between different fuels that abut each other during 

shipment by pipeline.

(e) From June 1, 2012 through June 1, 2014, NRLM diesel fuel produced by a facility 

that processes transmix is subject to the standards of §80.510(c), except that LM 

diesel fuel produced from transmix is subject to the sulfur standard of §80.510(a). 

This paragraph (e) does not apply to NRLM or LM diesel fuel that is sold or 

intended for sale in the areas listed in §80.510(g)(1) or (g)(2).

(f) Beginning June 1, 2014, LM diesel fuel produced from transmix is subject to the 

sulfur standard of §80.510(a), provided that the conditions in this paragraph are 

satisfied. Diesel fuel produced from transmix that does not meet the conditions in 

this paragraph is subject to the sulfur standard in §80.510(c).

(1) The fuel must be produced from transmix.

(2) The fuel must not be sold or intended for sale in the areas listed in 

§80.510(g)(1) or (g)(2).

(3) A facility producing 500 ppm LM diesel fuel must obtain approval from 

the Administrator for a compliance plan. The compliance plan must detail 

how the facility will segregate any 500 ppm LM diesel fuel produced 

subject to the standards under §80.510(a) from the producer through to the 

ultimate consumer from fuel having other designations. The compliance 

plan must identify the entities that handle the 500 ppm LM through to the 

ultimate consumer. No more than 4 separate entities shall handle the 500 

ppm LM between the producer and the ultimate consumer. The 

compliance plan must also identify all ultimate consumers to whom the 

refiner supplies the 500 ppm LM diesel fuel. The compliance plan must 

detail how misfueling of 500 ppm LM into vehicles or equipment that 

require the use of 15 ppm diesel fuel will be prevented.

(i) Producers of 500 ppm LM diesel fuel must be registered with EPA 

under §80.597 prior to the distribution of any 500 ppm LM diesel 

fuel after June 1, 2014.

(ii) Producers of 500 ppm LM must initiate a PTD that meets the 

requirements in paragraph (f)(3)(iii) of this section.

(iii) All transfers of 500 ppm LM diesel fuel must be accompanied by a 

PTD that clearly and accurately states the fuel designation; the 

PTD must also meet all other requirements of §80.590.

(iv) Batches of 500 ppm LM may be shipped by pipeline provided that 

such batches do not come into physical contact in the pipeline with 

batches of other distillate fuel products that have a sulfur content 

greater than 15 ppm. 

(v) The volume of 500 ppm LM shipped via pipeline under paragraph 

(f)(3)(iv) of this section may swell by no more than 2 % upon 

delivery to the next party. Such a volume increase may only be 

due to volume swell due to temperature differences when the 

volume was measured or due to normal pipeline interface cutting 

practices notwithstanding the requirement under paragraph 

(f)(3)(iv) of this section.

ppm LM received versus the volume delivered and used on an 

annual basis.

(vii) The records required in this section must be maintained for five 

years, by each entity that handles 500 ppm LM and be made 

available to EPA upon request. 

(4) All parties that take custody of 500 ppm LM must segregate the product 

from other fuels and observe the other requirements in the compliance 

plan approved by EPA pursuant to paragraph (f)(3) of this section. 

5. Section 80.572 is amended by revising the section heading and paragraphs (a) and
