E85 Ethanol
Industry Guidelines, Specifications and Procedures
Introduction
    The Renewable Fuels Association (RFA) is the national trade association for the U.S. fuel
ethanol industry. Membership is comprised of numerous ethanol producers, both large and small,
as well as suppliers to the industry and other interested parties. Founded in 1981, the RFA’s
primary objective is to promote public policy initiatives that increase the market for fuel grade
ethanol produced from a variety of feedstocks including grains, agricultural wastes, and various
biomass feedstock sources.
    As the ethanol industry has grown, so too has the Renewable Fuels Association’s areas of
responsibility to its membership. Today the RFA not only focuses on legislative/regulatory and
public policy type issues but also maintains several committees and task groups to address
industry needs. These committees include a technical committee to address various technical
issues and to assist with technical industry publications (such as this one). In addition, there are
plant and employee safety, environmental, and cellulosic committees monitoring efforts in each
of these respective areas. The technical committee also has an E85 task force to deal specifically
with E85 issues. Other committees utilize standing and ad hoc task forces and work groups as
well. These committees and task forces are comprised of representatives of our member
companies, staff, and, when necessary, technical consultants and other interested stakeholders.
The RFA provides support for educational outreach programs through its research and education
arm, the Renewable Fuels Foundation.
    The RFA promotes the use of fuel grade ethanol in all its legal applications. Fuel ethanol is
blended in over 70% of the nation’s gasoline. This includes not only conventional E10 (90%
gasoline/10% ethanol), and reformulated gasoline (RFG), but also developing markets such as
E85 for use in flexible fuel vehicles (FFVs) and mid level ethanol fuel blends. This document
focuses on the product quality and integrity of E85, which is of the utmost importance to the
Renewable Fuels Association and its members because, unlike ethanol as a blend component, in
this application it is the finished fuel. To promote the highest quality fuel possible, the
Renewable Fuels Association has put together this information offering a discussion of
specifications, properties and their importance as well as other important topics related to E85.
The purpose of this document is to serve as a condensed technical reference for manufacturers
and retailers of E85 and other interested parties who need such information. All RFA Technical
Publications and other RFA Reference materials are available on the RFA website at:

E85 Ethanol
Industry Guidelines, Specifications and Procedures
    While fuel grade ethanol is most widely recognized for its use in E10 gasoline/ethanol blends
there is growing awareness and use of what is commonly called E85. E85 can actually range
from 70% ethanol/30% hydrocarbons to 79% ethanol/21% hydrocarbons (discussed in more
detail later in this publication). E85 is currently restricted to use in FFVs.
Flex Fuel Vehicles: Several manufacturers currently offer vehicles that are capable of operating
on 100% gasoline or E85, or any mixture of the two. These vehicles are called flex fuel vehicles
(FFV) or variable fuel vehicles (VFV). Ford, General Motors, and the Chrysler Corporation, as
well as some foreign based manufacturers, all offer certain models as FFVs that operate on E85.
    It is estimated that there are over 7 million FFVs on the roads today. Through the
commitment of the U.S. automakers, nearly 50% of their vehicles sold by 2012 will be FFVs.
FFVs are growing in demand as consumers want a choice in fuels and desire to support
domestically grown transportation fuels. Fuel infrastructure is growing at a steady pace as well.
There are currently over 2,000 retail stations offering E85.
    A full list of FFV models for the past and current model years is available from the
Department                        of                         Energy’s                    website:
http://www.afdc.energy.gov/afdc/vehicles/flexible_fuel_availability.html This website also has
an     E85     station  locator    feature      to    find    a   fueling station    near    you,
http://www.afdc.energy.gov/afdc/ethanol/ethanol_locations.html. E85 should not be dispensed
into non FFVs as it could damage the vehicle. It could also result in significant fines for the
fuel retailer.
    There are six distinct areas of importance to initiating a successful E85 marketing program:
                Product Quality
                System Conversion and/or New Installations
                Transportation Considerations
                Safety Issues
                Retail Marketing Considerations
                Legal Compliance
Product Quality
    There are several issues regarding E85 quality, including the quality of the ethanol, the quality
of the hydrocarbon portion of the blend, and the quality of the finished blend. In addition,
adequate treatment with certain additives and proper care during transport and delivery, as well as
proper procedures for conversion and housekeeping, are also necessary.
E85 Quality
    At retail E85 should meet the property limits set forth in ASTM D 5798 Standard
Specification for Fuel Ethanol (Ed75-Ed-85) for Automotive Spark- Ignition Engines. The lower
case “d” in “Ed” stands for “denatured” ethanol meaning for instance Ed75 is 75 volume %
                                                                                                   4

denatured ethanol. Table 2 lists the property limits as well as designated test methods for E85.
The full ASTM specification has very detailed information regarding the importance of each
property. As such, testing frequency is not defined here. Each E85 manufacturer should evaluate
their own operation and process to set a testing frequency to ensure adherence to the ASTM
standards. The RFA has developed a quality assurance/quality control (QA/QC) guide entitled,
“Guidelines for Establishing Ethanol Plant Quality Assurance and Quality Control Programs,”
RFA Publication #040301, which may prove useful in setting up a fuel quality and oversight
program. This document is available on the RFA website: www.ethanolrfa.org.

** Note that certain states ban the use of MTBE/or other aliphatic ethers.
As some of the methods listed in this specification were not originally developed to evaluate high
ethanol content fuels, the ASTM DO2.08 Analytical Methods subcommittee has formed a Biofuel
Method Applicability work group to address concerns with the above listed method applicability
to fuel with an ethanol content greater than 10% volume.
Ethanol & Higher Alcohols, Hydrocarbons/Aliphatic Ethers, and Vapor Pressure: The limit
of the ethanol/higher alcohols and hydrocarbon portion of E85 varies by class. For instance,
                                                                                                        5
E85 Ethanol
Industry Guidelines, Specifications and Procedures
Class 3 requires less ethanol and allows a lower ethanol minimum. This is done to increase fuel
volatility (vapor pressure) to provide better cold start and warm up performance. Class 3 is
typically the winter grade, Class 1 the summer grade and Class 2 is typically inter-seasonal
(fall/spring). The minimum ethanol and higher alcohols in the specification takes into
consideration that the ethanol in the blend is denatured. Thus Class 1 E85, which would typically
contain 85% denatured ethanol, is required to meet a 79% minimum ethanol content.
Vapor Pressure: As discussed above, vapor pressure is altered based on historical climate
conditions and altitude. Table 2 of ASTM D 5798 lists the appropriate class by state, by month.
Class 1 (summer grade) requires a vapor pressure of 5.5-8.5 psi. Class 2 (spring/fall) requires a
vapor pressure of 7.0 – 9.5 psi and Class 3 (winter) 9.5 – 12.0 psi. Testing is currently underway
to determine if these ranges (established on older vehicle technology) are still appropriate or
require revision.
Note: Some states such as California have, or are developing, their own E85 standards.
It is often difficult to meet the minimum vapor pressure requirements with today’s lower
volatility gasolines. General Motors and the RFA conducted a study of various volatility
hydrocarbon blend stocks at varying levels. This included gasolines with vapor pressures of 5.5,
7.8, 9, 11.5, 12.5, and 15 psi as well as natural gasoline. The following table lists the “as tested”
(ASTM D 4953), ASTM Dry Vapor Pressure Equivalent (DVPE) of the fuels, as received.

The following figure shows the vapor pressure results (ASTM D 4953) for blending each
hydrocarbon at 15%, 20%, and 25% (i.e. E85, E80 and E75 respectively).
                                                                                                   6
E85 Ethanol
Industry Guidelines, Specifications and Procedures
Figure 1
As can be seen, for E85 (typically the summer grade), some blendstocks do not meet the 5.5 psi
minimum. For E80, some do not meet the 7.0 psi minimum and for E75 very few meet the 9.5
psi minimum. Selection of a sufficiently volatile (high vapor pressure) hydrocarbon allows the
final blend to meet minimum ASTM vapor pressure requirements when added at the correct
levels.
Seasonal Inventory Control: Retailers should exercise caution at seasonal changeover time.
For instance, a high inventory of summer grade, if not run down before cold weather, would be
below the specified vapor pressure and may adversely affect cold start and warm up performance.
Sulfur: Sulfur limits must be controlled because sulfur can damage the catalytic converter. Care
should be used in selecting denaturants because these hydrocarbons are the source of most sulfur
in denatured ethanol.
Methanol and Higher Alcohols: Methanol is held to low limits due to its corrosive properties,
while higher alcohols are controlled to ensure ethanol purity.
Acidity, pHe and Inorganic Chloride: These are limited to reduce corrosive properties.
Solvent Washed Gum/Unwashed Gum: Solvent washed gum can contribute to fuel system
deposits. The unwashed gum content is set to limit high boiling point components such as diesel
fuel. The difference between unwashed and solvent washed gum can be used to determine the
                                                                                              7
E85 Ethanol
Industry Guidelines, Specifications and Procedures
presence of non-volatile materials. More analytical testing would be necessary to identify the
exact material, which could be additive or additive carrier oils.
Copper: Copper is undesirable in fuels because it can decrease fuel stability thereby contributing
to increased gum formation.
Water: Water levels are controlled because excessive water levels may increase fuel system
corrosion.
Workmanship Clause: Section 5 of ASTM D 5798 also contains a workmanship clause which
states:
        “Fuel Ethanol (Ed75-Ed85) shall be visually free of sediment and suspended matter.
        It shall be clear and bright at the ambient temperature or 21°C (70°F), whichever is
        higher. The specification defines only a basic purity for fuel ethanol (Ed75-Ed85). The
        product shall be free of any adulterant or contaminant that can render the material
        unacceptable or its commonly used applications.”
Octane: A minimum octane for E85 is not specified. FFVs can tolerate the lower octane of
gasoline, i.e. 87 (R+M)/2. The RFA recommends that the octane not be posted because of
variations and testing expense. There is no requirement to post octane on an E85 dispenser. If a
retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect.
This number was derived by using ethanol’s blending octane value in gasoline. This is not the
proper way to calculate the octane of E85. Ethanol’s true octane value should be used to
calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These
calculations have been confirmed by actual octane engine tests.
Product Additization: ASTM D 5798 does not contain guidelines for additives such as corrosion
inhibitors or detergents/deposit control additives. Work in this area is ongoing. As such, the
RFA has not yet prepared a formal recommendation for additives to be used in E85. The
following discussion provides information on developing issues.
Corrosion Inhibitors: Nearly all ethanol producers add a corrosion inhibitor at a level sufficient
to treat the entire finished gallon of E10. This level would actually over-treat a gallon of E85.
However, since E85 is typically made from ethanol in common storage and E10 is the primary
blend, this is unavoidable at the present time.
Detergents/Deposit Control Additives: Recent studies have shown that E85 may, in some
cases, lead to development of fuel injector and/or intake valve deposits. Preliminary work
indicates that this may be a result of no detergents in the ethanol portion of the blend in
combination with high levels of corrosion inhibitor. This can be addressed through the addition
of detergents/deposit control additives. If an additive is used, the blender must rely on
information from the additive manufacturer. In addition to effectiveness, it should be confirmed
that any additive selected will remain soluble in varying blend levels of gasoline and ethanol, and
that the additive meets the “no harm” criteria, meaning it will not interact with other gasoline
additives present in a manner that would cause problems or reduce the effectiveness of other
additives. Common gasoline additives may not be compatible with E85. The recommended treat
rate of any additive should not be exceeded.
                                                                                                      8
E85 Ethanol
Industry Guidelines, Specifications and Procedures
Quality Assurance and Quality Control (QA/QC) Program: The product quality of E85 is
very important. The extent of any QA/QC program will depend on if the fuel is purchased pre-
blended and if it is splash blended or produced by automated blending. It may also depend on the
use of an in-house laboratory versus an independent laboratory, volumes sold, and individual
company operating producers. As noted earlier, the RFA has a QA/QC guidance document
available on its website.
Quality Assurance (QA) is a set of operating principles that, when strictly followed, a product
will be produced meeting the expectations of the customer. The program should provide
assurance of compliance to any applicable quality expectations as well as any regulatory
requirements.
Quality Control (QC) is a measure within a sample analysis methodology to assure that the
process is in control. Quality Control Programs ensure that the process is running as designed
and through various process checks, such as sampling methods, produce representative samples,
confirm that laboratory analyses are reliable, and verify that the reported results are suitable to
support decisions, and measure and document any uncertainty in analytical data.
Because of all the variables that determine the necessity and frequency of tests, QA/QC
procedure needs will vary by company.
E85 Blending
E85 may be blended at an ethanol plant or a petroleum distribution terminal. Some retailers have
retail dispenser systems that can blend E85 at the pump. The level of QA/QC and product
documentation may vary depending upon the location and method of blending.
Purchased Pre-Blended (Automated Blending): In this instance, you can usually rely on the
seller’s certificate of analysis or specification sheets. Certificates of Analysis (COA) can be
considered a legal document ensuring compliance to the agreed upon fuel quality standard. A
Certificate of Analysis should contain each of the following: Manufacturing/Blending, location,
Lot or Batch Identification, product name, date of analysis, test methods and results as performed,
and a signature of the person responsible for ensuring product quality or person performing the
analysis. In many instances, testing frequency should be indicated next to the test parameter and
if any typical properties are listed it must be indicated as such. Clear instructions on how to
correctly complete a COA will provide for the utmost accurate and truthful communication to the
customer. A COA may be duplicated and issued on a time based approach (daily, shift wise, etc.)
or process conditional approach (batch, shipment, etc.). Since E85 is usually manufactured at the
terminal as the truck is being loaded, a COA is more likely to show percent of blend and
properties of blend components and then typical properties on the blend. Even when a COA is
provided, it is a good practice to periodically spot check a few samples.
Purchased Pre-Blended (Splash Blends): Here the retailer can also rely on a COA, but again it
is good practice to periodically spot check samples. In this instance, where there is a greater
potential for mis-blends, more frequent sampling is advised.
Blender of Record: If your company is the blender of record, i.e. the entity actually blending the
two components, more stringent QA/QC is required. Automated blending equipment should be
checked periodically to verify blending accuracy. While automated blending is preferred, it is
often not available because of current low sales volumes of E85 in many areas. If your company
                                                                                                 9

is splash blending, you should meet with your transport drivers (or common carrier dispatchers
and drivers) to cover proper procedures. Pre-calculated blend cards should also be developed for
each tanker/compartment size. An example is provided in the table below.
As noted in the transportation section, the gasoline should be added to the compartment first.
This reduces the potential for build-up of static charge and improves blending (by introducing a
larger quantity into a smaller one).
Note that the components of E85 are blended on a volume basis of the components, corrected to
identical temperatures (usually 60°F). There are currently no volume correction tables for E85
blends.
Blenders of E85 should also monitor the properties of the blendstocks they use to manufacture
E85.
Base Ethanol Quality: The ethanol most often used at terminals to make the various blend
levels of E85 is the same ethanol that is used to make E10 blends. Consequently, much of the
ethanol used to make E85 meets ASTM D 4806 “Standard Specification for Denatured Fuel
Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel.” A
table listing the key properties defined by ASTM D 4806 is included in Appendix A.
For a more detailed discussion of the importance of these properties, refer to a copy of the
applicable specification. Copies of ASTM D 4806, ASTM D 5798, and other ASTM
specifications and standards may be obtained from:

Corrosion Inhibitors: The RFA also recommends that its ethanol producers add corrosion
inhibitors to the ethanol they produce. These additive recommendations can be found in RFA
Publication # 960501, “Fuel Ethanol Industry Guidelines, Specifications and Procedures,” which
is available on the RFA website. These additive recommendations are currently under review and
may be revised in the near future.

Industry Guidelines, Specifications and Procedures
Vapor Pressure: The vapor pressure of the hydrocarbon must be sufficient to raise the vapor
pressure of the finished blend to the minimum requirement at the blend levels specified.
Sulfur: The sulfur level of the hydrocarbon must be low enough that the finished blend complies
with ASTM specifications as well as any state or federal requirement.
Whether installing a new E85 system or converting an existing system to E85 there are certain
preparatory steps that must be taken. Additionally certain housekeeping procedures must be
adhered to. A useful information guide for retail E85 dispensing is the “Handbook for Handling,
Storing, and Dispensing E85,” (DOE/GO-102008-2450) April 2008, available on the internet at:
www.atdc.energy.gov/afdc/pdfs/41853.pdf. This and more information is available from the
Department of Energy website. www.afdc.energy.gov/afdc/ethanol. This website contains
excellent information on E85 installations and conversions as well as other information on E85.
Another useful website is the Petroleum Equipment Institute, www.pei.org/e85, which has a list
of suppliers with E85 compatible equipment. These guides and documents also provide
information on materials compatibility with E85. As a general guideline Table 4 lists compatible
and non-compatible metals while Table 5 lists Elastomers & Plastics.
                                                                                               11
E85 Ethanol
Industry Guidelines, Specifications and Procedures
In addition to following industry guidelines for fuel performance and federal regulations, there
are usually state and local regulatory guidelines that must also be adhered to. These requirements
may differ for terminal and retail fuel locations. These requirements may include state and local
fire codes as well as Department of Transportation (DOT) and OSHA Hazardous Materials
Regulations. As such, you should consult with state and local officials before beginning your
installation or conversion.
Authorities Having Jurisdiction (AHJ): In most cases local authorities having jurisdiction
(AHJ) have control over certain aspects of the installation. For example, they may require UL
listed equipment or manufacturer certified equipment. They may also waive such requirements
but require more frequent inspections.
Transportation
If product is blended in the truck compartments the gasoline should be loaded first to reduce
buildup of static charge. This also results in a more homogenous blend. Also the blends should
                                                                                                12
       E85 Ethanol
       Industry Guidelines, Specifications and Procedures
       be blended by compartment to ensure proper mixing. The truck should always be grounded
       during loading and unloading.
       Placarding: Transport trucks hauling E85 should be placarded as UN 3475 (ethanol and gasoline
       mixture). On January 28, 2008, the United States Department of Transportation, Pipeline and
       Hazardous Materials Safety Administration (PHMSA) issued a final rule creating a new proper
       shipping name and placard for E85. The RFA Safety Committee recommends that fuels
       containing greater than 10% volume fuel alcohol and less than 95% use the UN 3475
       identification. Mandatory compliance with the new placarding regulation began October 1, 2008.
       This mandatory placarding will direct “First Responders” to Guide 127 of the Emergency
       Response Guidebook (most recent publication 2008).
       Prior Commodities Hauled: Prior commodities hauled that are acceptable in trucks include E85,
       ethanol, fuel grade denatured ethanol, unleaded gasoline, unleaded racing gasoline, unleaded
       RBOB, unleaded CaRBOB, and natural gasoline. Equipment used to haul other commodities
       should not be used unless the equipment has been properly cleaned. Residual amounts of other
       products may contaminate the E85. For an expanded discussion of prior commodities hauled, as
       well as various equipment cleaning procedures, refer to RFA Publication # 960501.
       The same handling and product receipt safety and administrative procedures for gasoline are
       appropriate for E85. It is important to note two additional safety factors. E85 electrical
       conductivity is different than gasoline and is more prone to build a static charge. Additionally,
       E85 vapors are more easily ignitable than gasoline vapors. Mixtures of air and vapors will only
       burn or explode within a certain range of concentrations. The lean limit (or lower explosive
       limit) is where the mixture has just enough vapor to burn and the rich limit (or upper explosive
       limit) is where it is almost too rich to burn. E85 vapors often fall between the lean and rich limits
       meaning that it is a combustible mixture.
       Health Considerations: E85 should be handled in the same manner as gasoline. Personal
       exposure should be minimized. Like gasoline, E85 is flammable, poisonous, and may contain
       additives that can be harmful even with casual contact. E85 is poisonous and should not be
       consumed. Exposure to E85 can occur by inhalation (breathing in its vapors), absorption (getting
       it on the skin or in the eyes), or ingestion (swallowing it). The various symptoms of exposure to
       E85 and fuel ethanol are shown in Table 6.
                                                                                                         13
       E85 Ethanol
       Industry Guidelines, Specifications and Procedures
       Fire-fighting: Fuel ethanol and E85 fires require specific equipment, materials, and training.
       Recent testing of fire-fighting agents sponsored by the Ethanol Emergency Response Coalition
       using the Underwriters Laboratories, Inc. (UL) 162 test methodology revealed that conventional
       gasoline fire-fighting methods and chemicals are not likely to be effective on high ethanol content
       fuel fires. Ethanol blended fuels with greater than 10% ethanol require the use of a Polar Solvent
       or Alcohol Resistant (AR) type of Foam commonly known as an AR-AFFF. Traditional AFFF
       foams have limited to no ability to extinguish fire emergencies when the ethanol content is above
       10% by volume. AR type foams work on all alcohol variations of ethanol and gasoline blended
       fuels and would be the best use of fire response equipment. It should be mentioned that Dry
       Chemical fire extinguishing agents may also work on ethanol blended fuels, however, the dry
       chemical manufacturer must be consulted for appropriateness.
       The RFA has been an instrumental member of the Ethanol Emergency Response Coalition
       (EERC), which collectively produced a video entitled “Responding to Ethanol Incidents.” This
       video is available for free download at the RFA website, www.ethanolrfa.org. This video
       provides the necessary guidance for foam selection to address ethanol blended fuel fires. Another
       reference point for ethanol specific safety information is the EERC’s website,
       www.ethanolresponse.com. The EERC website holds a library of emergency and environmental
       information to help with both education and preparedness in the first response community when
       responding to ethanol related emergencies. There are contacts, MSDS, and technical bulletins
       available on this website.
       Safety training for distribution, retail, and emergency response personnel should be included
       specifically for ethanol blended fuels. Ethanol specific training provides the communication link
       between all parties to ensure an effective response to any emergency that may arise.
       Safety Codes: Safety standards for handling and storing E85 are the same as those for gasoline.
       The National Fire Protection Agency (NFPA) has two standards that apply to ethanol blends:
       NFPA 30, “Flammable and Combustible Liquids Code,” and NFPA 30A, “Automotive and
       Marine Service Station Code.” These codes contain information on refueling facilities, storage,
       and handling requirements for all flammable and combustible liquids. NFPA assigns ethanol
       fuels (including E95 and E85) to the same flammability class as gasoline. Copies of these
       standards can be obtained through the Office of the State Fire Marshal or the NFPA website. A
       sample material safety data sheet for E85 is shown in Appendix B.
                                                                                                       14

Industry Guidelines, Specifications and Procedures
Retail Issues
Marketing: E85 requires a special marketing effort. Prior to installation, the retailer should
determine if the local FFV population is sufficient to recoup any investment and return a
reasonable profit. FFVs can be identified by a unique character in the Vehicle Identification
Number (VIN), vehicle emblem or by the owner’s manual. The retailer should contact the RFA’s
Market Development Team for assistance in site assessment. Together, they can work with the
auto manufacturers and/or bureau of motor vehicles to identify the consumer FFV population by
zip code, provide information on fleet FFV population by zip code, local traffic counts,
partnerships with auto dealerships and more. If at all possible, some type of incentive should be
offered to entice the FFV owner to try E85. Examples of successful offers include “cents off,”
giveaways, celebrities, etc. There may be funds available to help with such promotions. Check
with RFA’s Market Development Team to see what is available. This team works directly with
other organizations that promote E85, such as state corn grower associations, the automakers,
American Lung Association, Clean Cities Coalitions, ethanol producers and, in some cases, state
and federal government. The bottom line is that any marketing program must advise consumers
of the fuel’s availability and advantages to get them to try it. For more information, the National
Renewable Energy Laboratory (NREL) has produced a business case for E85:
http://www.afdc.energy.gov/afdc/pdfs/41590.pdf
Gasoline Gallon Equivalence (GGE): E85 blends contain less energy than gasoline, which
results in fewer miles per gallon. Fuel cost, on a miles driven basis, must be considered. This is
sometimes called gasoline gallon equivalence (GGE). E85 is really E75 in the winter, E80 in
spring and fall, and E85 in summer. Ethanol does not contain as much energy as gasoline (lower
btu/gallon). In fact, E85 (E75, E80) contains about 73% to 76% the btu content of gasoline. The
actual impact on fuel economy can vary depending on the model of vehicle, vehicle driving
patterns, driving conditions, driver input, state of tune of the vehicle and other factors. Some
drivers and fleets have experienced fuel economy penalties below 10%, but most drivers will
experience a larger miles per gallon drop, typically in the 20% range.
It is important to promote the benefits of ethanol, and the value associated with those benefits. It
does not take the consumer long to figure out that they cannot go as far on a tankful of E85 as on
one of gasoline, but the value of the benefits may help. To offer comparable value the consumer
typically will want to drive the same distance on a dollar’s worth of E85 as a dollar’s worth of
gasoline. As a trade association, the RFA cannot offer recommendations on, or suggest how to
price E85. The price of E85 must be set by the retailer. However, to provide the retailer with
information on how a consumer might compare E85 on a cost per mile or GGE basis a
hypothetical example is provided in Table 7. The table uses gasoline meeting ASTM D 4814.
This is only one example and is on a btu basis only, and presents a worst case scenario. Some
drivers experience better fuel economy than the btu content would predict. Unlike gasoline,
which typically has a lower energy content in the winter (as much as 10%), E85 has a higher
energy content in the winter. Many FFVs take advantage of ethanol’s greater thermal efficiency,
which achieves more miles per btu than gasoline, although not enough to offset the total energy
content difference.
                                                                                                 15
E85 Ethanol
Industry Guidelines, Specifications and Procedures
Ethanol price 200 cpg less 51 cpg credit = $1.49. Unleaded regular 218.4 cpg
In the hypothetical example in the table the consumer pays less per gallon or tankful for E85 but
since fewer miles per gallon are achieved, the driving cost to the consumer is approximately the
same. If a consumer gets 20 mpg on gasoline and 15 mpg on E85, that equates to 400 miles on
20 gallons of gasoline and 300 miles on 20 gallons of E85. Most will not be willing to use E85
unless it is correspondingly less expensive than gasoline.
Retail Dispenser Labeling: There are certain specific labeling requirements for alternative
fuels, including E85. At a minimum, the pump must be labeled with the Federal Trade
Commission (FTC) required label as described in the Code of Federal Regulations (CFR) Title 16
Part 306. This label must identify the fuel as E85 and state the minimum volume percentage of
ethanol present. By stating 70% this covers all blend scenarios down to E75 and allows for the
denaturant. An example of a compliant FTC label is provided in Figure 2.
Figure 2
                                                                                              16
E85 Ethanol
Industry Guidelines, Specifications and Procedures
It is also recommended (and in some areas required) that the dispenser or nozzle have a consumer
advisory label that states this fuel is for use in FFVs only. Please contact RFA’s Market
Development Team for additional voluntary dispenser labels and suggestions.
Retail storage tanks containing E85 should be labeled in accordance with the API Color Coding
System with a bronze pentagon with E85 in black. See example figure 3.
Figure 3
The pentagon should be painted on fill line manhole covers. It is also recommended that similar
identification be placed on the tank fill line. Many states and local authorities may also require
specific labeling or signage so the retailer should check with state and local authorities.
There are various tax incentives available to encourage the expansion of E85 marketing. These
include incentives for fuel blending as well as for the cost of new installations or conversions.
VEETC: The Volumetric Ethanol Excise Tax Credit (VEETC) allows the blender of E85 to take
a credit of 45¢ per gallon of denatured ethanol used in the production of E85. The credit is
permitted on ethanol and up to 2% on the denaturant in the ethanol. There is specific guidance
for how to file for the VEETC on the RFA website. Ethanol producers who are blenders of
record can take the VEETC for the ethanol portion of E85.
Refueling Stations Credit: In 2009, the American Recovery and Reinvestment Act increased
the government incentive for new or newly converted refueling infrastructure. This credit now
allows a credit of 50% (capped at $50,000) per facility for alternative refueling installations such
as E85.
State Level Incentives: Many states also offer assistance for new or newly converted alternative
fuel installations. These change from time to time so the individual state should be consulted. To
explore incentives by state, click here: http://www.afdc.energy.gov/afdc/incentives_laws.html
Renewable Identification Numbers (RINs): The blender of record that produces E85 can
generate RINs which can be sold to companies who fail to meet their minimum renewable fuel
use requirement. The value of RINs is determined by marketplace conditions.
                                                                                                 17
E85 Ethanol
Industry Guidelines, Specifications and Procedures
Other Sources: Other organizations have also been instrumental in either providing a portion of
necessary funding or helping to identify additional funding sources. The RFA and the
Department of Energy has assisted with, or provided guidance for, numerous E85 installations.
Legal Considerations
As with all transportation fuels sold at retail there are various legal considerations. While many
of these regulations for E85 are identical, or similar, to gasoline some are unique to E85. Some
of the most important are discussed below.
Misfueling Prevention: Under the Clean Air Act and EPA guidance it is illegal for the retailer
to allow E85 to be dispensed into a non-FFV. Fines can be levied on the retailer or customer and
can be as high as $10,000 per offense. Even though the facility may be “self-serve,” the retailer
is considered responsible and can be fined for misfueling events. Dispensers and nozzles should
be clearly identified as “for use in FFVs only” and “check your owner’s manual.”
Labeling Requirements: As noted in the Retail Issues section, certain FTC labeling
requirements are required. State or local authorities may have additional labeling or product
identification requirements.
Equipment Requirements: As noted in the Installation and Conversion section, some states and
local jurisdictions may have specific regulations or guidelines on what equipment is approved for
E85 use.
Fuel Quality: Many states have fuel quality programs. These programs are usually (but not
always) part of a state’s Department of Weights and Measures. Many states have recently
adopted, or are currently considering adopting, fuel quality regulations that apply to E85.
                                                                                               18
