I. Introduction
The EPA is providing detailed information on how to prepare a complete Efficient Producer
Petition Process (EP3) petition for a new fuel pathway under the Renewable Fuel Standard (RFS)
program. Parties considering an EP3 petition are strongly encouraged to start by reviewing the
background information provided on the EPA's website on whether they qualify for this
expedited petition process.
This document provides details on the required information for EP3 petitions, including
recommendations on organization and formatting.1 Our objective is to help petitioners provide
all of the data that the EPA needs to complete the required lifecycle analyses as efficiently as
possible. EP3 petitions that do not meet the information requirements specified in 40 CFR
80.1416, as explained and clarified in this document and other the EPA guidance, will be
rejected as incomplete and no further action will be taken. In other words, the whole petition
will need to be resubmitted.
This document provides step-by-step instructions for preparing a complete EP3 petition. The
recommendations included in this document are based on the EPA's experience implementing
the petition process since its creation in March 2010. As we continue to receive and evaluate
more petitions, we expect to update this document as needed.
Compared to Version 1.3, this document includes minor updates on how to petition for an EP3
pathway when the facility generates D code 3 RINs for ethanol produced from corn and grain
sorghum kernel fiber.
1. Petitions that include generation of D code 3 RINs for ethanol produced
from corn and grain sorghum kernel fiber
EP3 petitions from ethanol producers seeking to generate D code 5 or 6 RINs for ethanol
produced through an EP3 pathway and D code 3 RINs for ethanol concurrently produced from
corn kernel fiber or a mix of corn and grain sorghum kernel fiber at the same facility, must
include the following information in their EP3 petitions.
Note that different test methods are required to determine the amount of cellulosic biomass
converted to ethanol depending on which feedstocks are used. Facilities that only use corn
feedstock would need to use a different test method than a facility that uses both corn and
sorghum as feedstocks.
Include the following in the Technical Justification section:
1. In the Technical Justification section of the petition, summarize the status of the
facility's registration application to generate cellulosic biofuel (D code 3) RINs for
ethanol produced from corn kernel fiber or corn and grain sorghum kernel fiber.
1 The information requested in this document is based on the information requirements for petitions outlined in
the RFS regulations at 40 CFR 80.1416(b).
3
-------
2. As part of the mass and energy balance data provided in the EP3 Calculator, the volumes
of cellulosic ethanol must be reported separately from the volumes of ethanol produced
from corn starch.
II. Section-by-Section Instructions
As part of our efforts to streamline the petition review process, the EPA is asking petitioners to
prepare their application packages using the recommended organization and format provided
in this document. The following sections go through each part of the petition outline and
provides guidance on what to include in each section.2
For the EPA to complete its evaluation of these petitions, it is necessary for the Agency to
publicly disclose certain information about requested pathways (e.g., the name of the company
that submitted the petition, the name and location of their biofuel production facility, the
type(s) of feedstocks used, the type of fuel produced and the type of production process
technology). For this reason, the EPA requests that certain sections of the EP3 petition include
no information claimed as confidential business information (CBI). Below, these sections are
marked as "(No information claimed CBI)."
We also recognize that petitioners may feel it is important to claim as CBI certain technical
information. Petitioners who wish to claim certain information as CBI should clearly mark all the
information claimed as CBI as precisely as possible. We ask petitioners to clearly mark each and
every page that includes information claimed as CBI. The header of all such pages should say
"Contains information claimed as CBI," and the header should also include an explanation of
how such information is marked. For example, the header could explain that information
claimed CBI is included in brackets or highlighted yellow.
1. Cover Sheet (No information claimed CBI)
We ask that every petition include a one-page cover sheet. The cover sheet serves as a quick
reference, designed to help the EPA staff efficiently and systematically process and review
incoming petitions. An example Cover Sheet is provided in Appendix 2.
Date Submitted
Enter the date that the petition is submitted to the EPA.
Company Full Name
Enter the official name of the company submitting the petition. Enter only one company name.
2 We ask petitioners to use the section headings specified below and in the table of contents (e.g., A. Cover Sheet,
B. Feedstock, C. Production Process, and so on). For more instructions on formatting see Appendix A.
4
-------
Name of Ethanol Production Facility
Give the name of the ethanol production facility associated with the petition.3 Please use a
brief name (we recommend no more than three words), as this will be the name used in the
EPA Moderated Transaction System (EMTS) and the EPA's determination document. A company
submitting petitions for multiple facilities should make sure that each facility has a unique
name. For example, facilities could be named after the Company and the city where they are
located, e.g., Acme Washington, Acme Washington II, Acme Detroit. Enter only one facility per
petition.
Location of Ethanol Production Facility
Specify the location (city, state, country) of the facility that will produce the ethanol associated
with the proposed pathway.
Fuel Pathway Requested
Enter the fuel, feedstock and production process technology and RIN D code for each pathway
requested. A single petition may involve more than one fuel pathway. For example, the petition
may request pathways for corn starch ethanol, grain sorghum ethanol qualifying for renewable
fuel (D code 6) RINs and grain sorghum ethanol qualifying for advanced biofuel (D code 5) RINs.
Add rows to the table as necessary to include all of the fuel pathways requested. Below is an
example of how to fill out the table of requested fuel pathways.

Petition Request
Choose one of the one-sentence descriptions listed below summarizing what the petition is
requesting. EP3 petitions are currently limited to the following options:4
1. Efficient Producer corn starch ethanol pathway to generate D code 6 RINs for a facility
that only uses only corn as feedstock
2. Efficient Producer corn starch ethanol pathway for D code 6 RINs for a facility that uses
corn and grain sorghum as feedstock
3 In this document ethanol refers to undenatured ethanol.
4 Ethanol producers with a request other than those listed here may petition the Agency pursuant to 40 CFR
80.1416. Such petitions will not be eligible for the Efficient Producer petition process and will therefore take
significantly longer to review. The review time will depend on the number and type of other higher priority
petitions under review by the EPA.

-------
3. Efficient Producer grain sorghum ethanol pathway for D code 5 or 6 RINs
Primary Point of Contact
Provide the requested contact information (see Appendix B) for the primary point of contact
(POC) for the petition. Include only one POC per petition. The EPA recommends that the POC
should be affiliated with the company listed on the cover sheet under Company Full Name. If
the POC is not affiliated with the lead organization, at least one appropriate official from the
lead organization should be listed under the "Additional Contact Info" section of the Petition
Cover Sheet, and included in any subsequent meetings or calls related to the petition. The EPA
will send all communications regarding a petition to the POC, and it is the POC's responsibility
to disseminate information to other parties associated with the petition. These
recommendations are intended to reduce duplicative communications between the EPA and
parties associated with a petition.
2. Technical Justification
Include a brief technical justification (typically 1-2 short paragraphs), that includes a summary
of the proposed pathway and any important aspects that you would like the EPA to consider
when evaluating the petition.
3. Feedstock (No information claimed CBI)
Provide a brief statement certifying the types of feedstocks that are used in the requested
pathway.
If you your petition requests an Efficient Producer corn starch ethanol pathway to generate D
code 6 RINs for a facility that only uses only corn as feedstock, include the following statement:
"I certify that the [insert facility name] dry mill ethanol production facility uses only corn as a
feedstock to produce ethanol."
If your petition requests an Efficient Producer corn starch ethanol pathway for D code 6 RINs
for a facility that uses corn and grain sorghum as feedstock, include the following statement: "I
certify that the [insert facility name] dry mill ethanol production facility uses only corn and grain
sorghum as feedstocks to produce ethanol."
If your petition requests an Efficient Producer grain sorghum ethanol pathway for D code 5 or 6
RINs, include the following statement: "I certify that the [insert facility name] dry mill ethanol
production facility uses only corn and grain sorghum as feedstocks to produce ethanol."
4. Production Process
Provide a brief statement certifying that the production process used to produce ethanol
through the requested pathway(s) is a dry mill ethanol production process. For more
information about what constitutes a dry mill ethanol production process, see Section 1.4.1.1
("Dry Milling Technology") of the February 2010 Renewable Fuel Standard Program (RFS2)
Regulatory Impact Analysis (EPA-420-R-10-006).
6
-------
For example, the statement could say the following: "I certify that the requested pathways for
ethanol produced by [insert facility name] use a dry mill production process where corn starch
and grain sorghum feedstocks are ground into a coarse flour, also known as "meal"; the meal is
cooked into a hot slurry with the addition of enzymes to produce a mixture commonly known
as "mash"; the mash is fermented with the addition of yeast to produce ethanol, carbon dioxide
and solids from the grain and yeast, known as "fermented mash"; the fermented mash is
distilled to produce a mixture of ethanol and water, and a residue of non-fermentable solids,
also known as "stillage"; the mixture of ethanol and water is dehydrated to produce 200-proof
ethanol; and the primary coproducts/byproducts are carbon dioxide, distillers grains, solubles,
syrup and vegetable oil."
5. Process Energy
Provide a brief statement certifying that the dry mill process for the requested pathway uses
one or a combination of the following sources for all of its process energy: electricity from the
grid, natural gas, coal, biogas or biomass. If the requested pathway uses biogas for process
energy, briefly describe the sources of the gas. At this time to qualify for the EP3, all biogas
used for process heat fuel must meet the RFS regulatory definition for biogas or treated biogas
at 40 CFR 80.1041. Furthermore, the biogas must be sourced from one or a combination of the
following sources: landfills, municipal wastewater treatment facility digesters, agricultural
digesters, separate municipal solid waste (MSW) digesters, or other waste digesters. See the
July 2014 RFS rule (79 FR 42128) for more information on qualifying sources of biogas.
If the requested pathway uses biomass for process energy, briefly describe the sources of the
biomass. Note that to qualify for the EP3 petition process, all biomass used as process energy
must meet the RFS regulatory definition for crop residue at 40 CFR 80.2. See the July 2014 RFS
rule for more information on what the EPA considers to be a crop residue for the RFS program.
6. Coproducts
Provide a brief statement certifying that all of the distillers grains or distillers grains and
solubles co-product produced as a result of the requested pathways is intended for use as
animal feed. This section should also provide a brief description of the coproducts resulting
from the requested pathways and their intended uses. For example, explain whether the facility
sells wet or modified distillers grains, produces vegetable oil coproduct through fractionation or
extraction, produces any additional co-products, etc. If your facility uses distillers grain for
another purpose, such as biogas production, you may submit a non-EP3 petition pursuant to 40
CFR 80.1416.
7. Mass and Energy Balance Data
A mass and energy balance must be included for every new pathway requested. To provide the
required mass and energy balance data, petitioners should use the EP3 Calculator, available for
download on the Agency's EP3 petition process web page.5 This spreadsheet tool is designed to
5 https://www.epa.gov/renewable-fuel-standard-program/how-prepare-efficient-producer-petition-under-
renewable-fuel
7
-------
automatically calculate lifecycle emissions based on the mass and energy balance data entered.
Petitioners should fill out the EP3 Calculator and attach it to their EP3 petition. For detailed
instructions on using the EP3 Calculator, including the formulas and emissions factors used in
the calculations, see the How to Use the EP3 Calculator Version 1.4 document available for
download on EPA's EP3 web page.
The EP3 Calculator submission should include average annual mass and energy balance data
over the past year and/or projected into the future. Data may be entered in the EP3 Calculator
for a daily, monthly or annual basis. If the mass and energy balance data provided are based on
projected process improvements, provide a brief explanation (less than one page) of the energy
saving technologies and other process improvements that will (or have been) undertaken to
improve the facility's future efficiency compared to its historical performance.
In cases where a facility uses corn kernel fiber, grain sorghum kernel fiber or a combination
thereof as feedstocks to co-produce ethanol, and seeks to generate cellulosic biofuel (D code 3)
RINs for such ethanol, the volumes of cellulosic ethanol must be reported separately from the
volumes of ethanol produced from corn starch or grain sorghum starch. For details, see the
instructions for the EP3 Calculator.
The data provided should demonstrate how the requested fuel pathway will meet the
applicable lifecycle emissions reduction threshold (e.g., 20% emissions reduction for renewable
fuel D code 6 RINs, 50% emissions reduction for renewable fuel D code 5 RINs) using the
methodology and formulas contained in the EP3 Calculator. If you submit an EP3 petition that
does not demonstrate adequate lifecycle emissions reductions the EPA will return it as
incomplete.
Should the petition be approved, the average lifecycle emissions for the ethanol produced at
the facility will need to be calculated and recorded over a 365-calendar day rolling average. The
EP3 Calculator is designed to help perform these calculations as well.
8. Certification by the Responsible Corporate Officer (RCO)
EP3 petitions should include a signed statement by the RCO of the company (or facility)
submitting the petition,6 certifying that the information provided is accurate and the company
6 For reference, a definition for responsible corporate officer is provided at 40 CFR 122.22:
