0.0 Purpose of the document

   This document describes the policies of the U.S. Environmental Protection Agency's
(EPA's) SmartWay Technology Program for SmartWay trailer designation and
SmartWay trailer aerodynamic device verification.  It is designed to work in conjunction
with other EPA SmartWay documents including: the online listing of verified
technologies;  SmartWay test protocols; SmartWay technical papers; and the "frequently
asked questions" (FAQ) document. While this document details how the programs
work, the FAQ includes some context for certain policy decisions.
1.  SmartWay Technology Program Overview


      The EPA SmartWay Technology programs are a set of voluntary programs
designed to assist fleets in finding the most fuel-efficient long-haul tractors and trailers
available on the market.  SmartWay verifies the fuel-savings performance of certain
types of devices that can be used on  a long-haul, Class 8 tractor or trailer. When these
verified fuel-savings devices are installed on trucks, the trucks are eligible to be
designated as SmartWay Trailers or SmartWay Tractors. This is illustrated in Figure 1.
              Figure 1. Overall Requirements for SmartWay Tractors and Trailers


While many technologies may provide fuel savings, SmartWay only verifies technology
types that have a variety of commercially available products, have validated fuel savings
performance levels, and there is clear need to assist fleets in differentiating between
individual products. The individually verified technology types are described in Table 1.

While any fleet will benefit from using SmartWay designated tractor/trailers, and/or
verified technologies, the SmartWay programs are intended to support SmartWay
Partner fleets with long-haul operations to improve overall freight efficiency. SmartWay
Partners know that how you use technology is as important has what technology you
choose. Through streamlined freight operations, incorporating practices to
accommodate the use of fuel-saving equipment, and proper maintenance, SmartWay
Partners apply technology for maximum fuel savings and return on investment.
2.  SmartWay Trailers


      2.1 Why Should I Use a Designated Trailer?

      Fleets that use a SmartWay Trailer can have confidence that the combination of
verified tires and aerodynamic devices will provide fuel savings over a conventional
trailer.  These fuel savings are determined for typical long-haul, tractor-trailer based
operations, making a designated trailer a good starting point for fleets that may not have
extensive testing resources to determine the fuel savings specific to their operations.

      Currently, SmartWay Partners that use a SmartWay Trailer or Tractor may
request EPA permission to use a SmartWay logo on the outside of the vehicle. This
shows that a fleet uses operational practices and SmartWay-verified technologies to
deliver goods in the most efficient way.

      Trailer manufacturers may create packages that qualify for SmartWay
designation and request permission to use the SmartWay internal logo to show
prospective buyers that the trailer is SmartWay designated.  This internal logo is
different than the external logo sticker that a fleet may use on its trailers.  The internal
logo is temporary and designed to help fleets decide which trailer(s) to purchase. The
temporary logo is not used beyond the showroom.


      2.2 What is a SmartWay-designated Trailer?

      SmartWay van and refrigeration trailers use SmartWay-verified low rolling
resistance trailer tires and SmartWay-verified aerodynamic devices. When used
together, these tires and devices can total 6% or more fuel savings over traditional
trailers.  SmartWay trailers are currently limited to 53 foot box trailers that are "van" (i.e.,
non-climate controlled cargo bay) or refrigeration trailers used for the long haul
operations. There are two levels of SmartWay designation for trailers that differ by the
aerodynamic drag reduction achieved. These are detailed in Table 2.

      The SmartWay Trailer and SmartWay Elite Trailer designations apply to both van
and refrigeration trailers.  Because all verified aerodynamic components are tested on
van trailers, some engineering judgment is necessary when fleets select components
for use with refrigeration trailers.  In cases of uncertainty, the fleet should consult the
FAQ, SmartWay technical papers, and the EPA staff.

      The SmartWay designation can apply to new trailers as well as existing trailers
that are retrofitted with SmartWay-verified tires and aerodynamics.
      2.2.1 Tires
      EPA verifies new tires and retread technologies that are suitable for use on
class 8 line haul tractor trailers.
                                    New Tires
      New tire manufacturers must demonstrate that a tire model has a rolling
resistance coefficient at or below the target values (in kg force/metric ton) using either
the SAE J1269 tire rolling resistance test method (with the conditions established in
table 3 of SAE J1269) or the ISO 28580 rolling resistance test method.
      For multi-position new tires, if the tire qualifies for verification as a trailer tire, it
may qualify for verification at all positions. If it qualifies for verification as a steer tire, it
may also qualify for verification as a drive tire. Because some tires are intended for
specific operations, consult with the tire manufacturer and SmartWay-verified list to
determine if a tire is appropriate for your application.

      A minimum sample of three tires is to be tested. The average rolling resistance
coefficient of the sample is the value to be compared with the new tire target values
listed Table 3.

      Manufacturers of retread technologies must demonstrate that the tread has a
rolling resistance coefficient at our below the retread target values using the ISO 28580
rolling resistance test method.

      Prior to testing, the retread technology/tread is affixed to a new tire casing that
has been buffed (i.e., tread removed) to a specified depth using the applicable retread
manufacturing process.  Either a standard or an alternate test casing is used in testing.
Typically, a standard test casing is used for all treads for conventional width tires (dual
tire axle configurations).  Manufacturers wishing to test using an alternate casing must
contact EPA to receive approval prior to testing.

      For retreads used on single-wide tires, manufacturers may request to use an
alternate casing made from any currently EPA verified single-wide new tire.

      A minimum  sample of three retreads are tested. The average rolling resistance
coefficient of the sample is the value to be compared with the retread technology target
values listed Table 4.

       2.2.2 Aerodynamics
       For fleets interested in aerodynamic devices for trailers, the SmartWay online list of
verified products is a good place to start.  Each product is placed into performance bins of
1 %, 4%, 5%, or9% or more fuel savings over traditional trailers.  In general, these
performance bins do not prescribe a specific device type (e.g., skirt, end-fairing) but there are
some constraints. Table 5 shows the performance bins.

Note: Fuel savings bins are based upon a long-haul, combination tractor-trailer
configuration at highway cruise (65mph) in controlled testing.
        Using the SmartWay aerodynamic device verification webpage, fleets can select
individual devices to meet their performance needs, or a combination of devices that total the
desired level of fuel savings. For example, the SmartWay trailer threshold of at least 5% fuel
savings could be achieved by using a 5% device alone, or by combining a 1 % and 4%
device.  A SmartWay Elite trailer designation could be achieved by using a 9% package (2 or
more devices verified together) or pairing a 4% and a 5% device that were verified
individually. Figure 2  illustrates the flexibility fleets have when choosing verified  components.

      When combining devices verified individually, a fleet should understand that the
overall performance may be somewhat different than the simple sum of the devices'
individual fuel savings (i.e. a 4% device plus a 5% device may not always total 9% in  fuel

savings).  For these cases, fleets should evaluate the combined performance of their unique
package in their operations.  Consulting  with the

       To avoid uncertainty in fuel saving performance, SmartWay encourages fleets to use
verified packages (i.e., components tested together)  listed on the EPA website. Verified
packages consist of two or more trailer devices tested together to demonstrate a satisfactory
fuel savings through SmartWay's testing protocols. EPA will only list combinations of devices
as a verified 9% package if they've demonstrated they work together by being tested in that
configuration using SmartWay protocols.

3. SmartWay Trailer Aerodynamic Devices
       3.1  Why verify a trailer aerodynamic device?
       For a device to qualify a trailer for SmartWay designation, the aerodynamic
component must be SmartWay verified. Hence, aerodynamic device manufacturers are
strongly encouraged to apply for SmartWay verification for their device(s).  Using a
SmartWay Trailer is important to fleets that want to improve their fuel efficiency and may
aid fleets operating in California2.
       Manufacturers that verify their trailer aerodynamic devices  increase the
confidence their customers have that the product will work for a long-haul fleet.
 The California Air Resources Board (CARB) heavy-duty, tractor-trailer regulation requires fleets operating in
California to use SmartWay Trailers but does provide some exemptions. Any fleet operating in California should
contact CARB to determine if they must comply with the rule.
                                                                                      10

Verification through SmartWay's robust protocols and review process can be critical to
product acceptance.


      3.2 What are SmartWay-verified aerodynamic devices?

      SmartWay verifies aerodynamic equipment for use on long-haul, box and
refrigerated trailers. SmartWay "verifies" the fuel saving performance of these devices
or combinations of devices relative to a traditional baseline trailer (no aerodynamics
components used). The fuel saving performance is based on manufacturer conducted
testing using SmartWay's testing protocols.

      The SmartWay testing protocols indicate performance at highway cruise
conditions (65 mph), with a specific tractor-trailer configuration. Tests are conducted in
controlled testing conditions to facilitate comparison of different tests - an apples-to-
apples comparison. Fleets operating largely at high cruise speeds with similar
configurations will achieve in-use performance most similar to the test results.  Fleets
may want to use engineering judgment to project how a device may perform for their
unique operating conditions.  EPA has presented research to assist fleets in
understanding how their real-world results may vary from controlled test results.

      SmartWay-verified aerodynamic devices are verified based upon manufacturer
provided data using at least one SmartWay testing protocol. The method(s) used to
verify a device is indicated by having one or more marks ("/" or "*" symbol) in the
appropriate column(s) in the online verified device table. For devices verified prior to
2014, the manufacturer used a track test protocol based on an industry standard with
additional SmartWay constraints.3  These devices are still considered verified and have
a "/" in the "Pre-2014 SmartWay Track Test" column. In this case, the previously
verified devices may be re-tested using one of the 2014 protocols to add an additional
mark ("/" or "*" symbol) for each new method used. (See section 3.4 for an
explanation of the "*"' and "*" symbols.)

      SmartWay encourages all previously verified manufacturers to update their
testing with the 2014 protocols to increase fleet confidence  in their devices'
performance.  Devices newly verified (in 2014 and  later) were tested using one or more
of the updated protocols.  These would not have a "/" in the "pre-2014" column but
would indicate the 2014 method(s) used in the verification.  Figure 3 below illustrates
the new matrix format for the online listing of SmartWay verified aerodynamic devices.
3 The original SmartWay track test was based on the Society of Automotive Engineers Fuel Consumption Type II
Procedures (SAE J1321,1986 reaffirmed) with additional, SmartWay-specific constraints.
                                                                               11

      A fleet can select a trailer aerodynamic
product by name from the SmartWay online
listing. This matrix only lists products that have
been verified using SmartWay protocols. In
cases where the product includes more than
one component, fleets know that they were
tested together if it is listed under a single name
and must be used in the tested configuration to
realize the verified performance levels.  For
Elite packages, a fleet selecting one  that is
listed by name knows that it was tested in that
configuration.
Will it work in my fleet?

SmartWay has conducted research to help
fleets understand how to translate results
from controlled verification testing to
performance projections in their own
operations.  This includes understanding the
trends at slower operational speeds, different
equipment settings (e.g., different tractor-to-
trailer gaps, different trailer axle positions),
and other key parameters.  For more
information, please refer to the SmartWay
webpage and links to SmartWay research.
      Fleets have the flexibility to select individually verified products from performance
bins and add them to reach a fuel-savings goal.  For example, a 1 % device may be
added to a 4% device to total 5% fuel savings.  Fleets can do the same to make
additive "ad-hoc" SmartWay Elite packages. While this additive flexibility can be useful
- especially where a trailer may already have a device and the fleet wants to add a
complementary component - fleets should understand that the benefits may vary from
the simple addition of the projected fuel savings.

      Fleets using a simple performance-addition approach should plan for additional
variability in return on investment calculations.  Fleets must also exercise good
engineering judgement and avoid combining individually verified devices that may not
be aerodynamically complementary (e.g., side skirts and undertray systems, small tails
with large tails, etc).  Fleets should  consult with SmartWay or the manufacturer if they
have questions regarding combining individually verified product that may not be
aerodynamically compatible.

      Fleets should review the online verified product matrix to see which verification
method or methods (i.e., track test,  wind tunnel, coastdown,  or CFD)  were used to verify
the product performance.  Fleets may use products  verified using  a method they prefer
or consider products tested using multiple methods.4 Verified products tested using
more than one SmartWay protocol will have mark in more  than one column.  A check
("/") will be used for the verification method and an additional mark for any additional
methods where the manufacturer has tested using that SmartWay protocol.  See Figure
3 for an illustration.  Find the listing  at:
http://www.epa.gov/smartwav/forpartners/technology.htm under the aerodynamics tab.
 Note that different methods provide slightly different types of results. EPA has provided brief introductions to
each 2014 test method that will help fleets understand the strengths and weakness of each type of testing.
                                                                                13

3.4 How do manufacturers verify devices?


      Manufacturers of commercially available trailer aerodynamic devices may
request to have their products verified by SmartWay. Verification can only be obtained
through applying to SmartWay and device testing. The manufacturer(s) must conduct
testing at their own expense using SmartWay verification protocols.  Products may not
be verified  by claiming that they are similar to another previously verified device.
Manufacturers of a previously verified device must notify SmartWay if they wish to
modify the  device in a way that could impact its aerodynamic performance.  Whether it
is a new product or a  potential modification to a previously verified device, the process
always begins with contacting SmartWay via the Tech Center(S)epa.gov mailbox.
      Once the manufacturer has contacted
SmartWay and received approval from EPA
for its test plan, the manufacturer will test the
product using one or more of the SmartWay
protocols. These may be found online at
http://www.epa.gov/smartwav/forpartners
/manufacturers.htm.   EPA reserves right to
observe testing performed for the purpose of
SmartWay verification. EPA may ask the
manufacturer questions regarding the product
(e.g., its intended use, dimensions and
mechanical details, and operating principle) or
its testing. At the conclusion  of testing, the
manufacturer must submit the test report
using the SmartWay format. While the device
manufacturer may contract with a testing
organization, EPA considers the device
manufacturer the applicant and responsible for
all materials submitted in the  verification
process. EPA will review the report and
determine if the device has properly
demonstrated fuel savings using SmartWay
test protocols.   If so, SmartWay verification is
granted through letters to the manufacturer and
page.
  What constitutes a modification?

  Modifying equipment to meet a fleet's
  needs is a part of the trucking business.
  While SmartWay understands there may
  be some refinement of a product to fit a
  fleet requirement, the fuel savings are
  verified for only the configuration tested.
  Modifying it may change the projected
  benefit. Manufacturers of a previously
  verified device must notify SmartWay if
  they wish to modify the device in a way
  that could significantly impact its
  aerodynamic performance based upon
  sound engineering judgement. EPA
  reserves the right to either: approve the
  modification through testing; or, identify
  the prospective change as a new product.
  Modifications  will not be listed separately
  but may be noted as part of the original
  listing.  SmartWay may determine the
  device is "new" if is substantially different
  from previously verified device in its
  characteristics or its principles of
  operations.
product posting on the SmartWay web
      SmartWay verification of aerodynamic devices is based upon fuel savings
relative to a traditional tractor-trailer at highway cruise (i.e., 65mph). When using the
track test protocol it is necessary to use the "percent fuel saved" result and not the
"percent  improvement."  Fuel savings results are reported to the one-hundredths place
- that is,  two decimal places such as "5.65%."  However, for determination of
aerodynamic bins SmartWay will truncate the reported result to make an integer. For
                                                                                14

-------
 USEPA SmartWay Trailer and Aerodynamic Device Program Policy (vl, February 2015)   Page 15 of 17


example, "5.65%" would be considered a "5%" for determining bins. A "4.93%" would
be place into the "4%" bin.

      When products are tested using multiple SmartWay protocols,  it is possible to  get
slightly different results. Devices will be binned based upon the first verification testing
method submitted to SmartWay.  Optional, supplemental testing using other methods
will be reviewed by EPA and, if it meets the same threshold (i.e., a device verified at 4%
producing results of 4.15% fuel saved using a second method) using  a SmartWay
protocols,  it will earn the product a secondary check ("/") in the online verified device
matrix for that method. In other words, to earn a check ("/") for the verification for any
additional  test methods, the results must meet the threshold for the same category.
Devices from all the verification categories (i.e., 1%, 4%, 5%, and 9%) have the
opportunity to earn  additional marks for using additional SmartWay protocols providing
they meet the same threshold outright.

      When reviewing results from a secondary test method for a device already
verified  in  the 5% or 9% categories, EPA will apply a tolerance. In cases where the
second  result is no  more than -1 % fuel savings below the first result,  EPA will approve
this test and different mark ("*" symbol) will be added to the appropriate column. For
example, SmartWay may verify an Elite package based upon the first test method used
by the manufacturer.  This result must exceed 9% fuel savings. If the same device is
tested using another method, SmartWay would apply a 1 % tolerance - that is 8% or
greater fuel savings - in order to receive a star ("*"  symbol) in the column for that
method. Table 6 summarizes the use of the different symbols.  (See Figure 3 for an
illustration of the use of symbols in the verification table.)

      Manufacturers wishing to be verified may test and submit data using the
SmartWay track test,  wind tunnel, or coastdown protocols.  While  use of computational
fluid dynamics (CFD) programs to evaluate trailer aerodynamic products is encouraged,
currently EPA will review CFD as supplemental testing. That is, EPA will evaluate CFD
for a product verified using another method, and determine if the technology
performance qualifies for a mark ("/" or "*") in the CFD  column.  As  the SmartWay
program evaluates  CFD methods with trailer technologies, this CFD verification policy
may change based upon EPA research as well as input from  fleets, manufacturers, and
testers.

4.0 SmartWay label and trademark


      Manufacturers with equipment meeting the SmartWay-designated and
SmartWay-designated Elite trailer specifications may be eligible to use official
SmartWay graphics. The SmartWay Graphics Standards and Usage Guide
(http://www.epa.gov/smartwav/forpartners/documents/logo-use/420b11014.pdf)
provides for general information regarding logo use.  Current SmartWay licensees
(trailer manufacturers) have a signed EPA-designated SmartWay Mark License
Agreement on file with U.S. EPA. Updated versions of the guide and agreement that
address technical specifications, graphics standards and logo usage will be available in
the next several months.
5.0 SmartWay resources


      SmartWay technology programs are intended to help fleets find the fuel saving
technologies that provide real savings and work for their operations.  As a result EPA
provides a variety of technology resources for fleets. These are summarized below in
Table 7.
                                                                            16
