Introduction

       The final rulemaking for the Renewable Fuel Standard (RFS) program was signed
by the EPA Administrator on April 10, 2007 and published in the Federal Register on
May 1, 2007 [72 FR 23900].  The program began on September 1, 2007.  To assist
regulated parties, we have collected questions pertaining to a variety of implementation
issues and generated responses to those questions.

       This document was prepared by EPA's Office of Transportation and Air Quality
(OTAQ).  It includes new questions not addressed in previous versions of this document
(see EPA document EPA420-F-07-041, May 2007 and EPA Document EPA420-F-07-
04la, September 2007). We will continue to update this document periodically as new
questions arise.

       Regulated parties may use this document to aid in achieving compliance with the
RFS program regulations. However, this document does not in any way alter the
requirements of these regulations. While the answers provided in this document
represent the Agency's interpretation and general plans for implementation of the
regulations at this time, some of the responses may change as additional information
becomes available, or as the Agency further considers certain issues.

       This question and answer document does not establish or change legal rights or
obligations. It does not establish binding rules or requirements and is not fully
determinative of the issues addressed.  Agency decisions in any particular case will be
made applying the law and regulations on the basis of specific facts and actual action.

       While we have attempted to include answers to all of the questions submitted to
us, the necessity for policy decisions and/or resource constraints may have prevented the
inclusion of certain questions. Questions not answered in this document will be answered
in subsequent updates. Questions that merely require a justification of the regulations, or
that have been previously answered in the preamble to the regulations and require no
further elaboration have been omitted.

1.      Valid renewable fuels and Equivalence Values

1.1     If I have a renewable fuel that was assigned a specific Equivalence Value in
       regulation Section 80.1115, but I don't think that Equivalence Value is right for
       my product, what options do I have?

       A:     Producers or importers of renewable fuel may submit a petition to the
             EPA requesting a different Equivalence Value from that assigned in the
             regulations.  However, the petition must use the calculation methodology
             described in regulation Section 80.1115(d). In short, if the energy content
             or renewable content of a producer's or importer's product differs from
             the values used by EPA to calculate the Equivalence Values specified in
             regulation Section 80.1115(b), the party may be entitled to an alternative
             Equivalence Value.

1.2     I will be making renewable gasoline from renewable crude. Section
       80.1115(b)(6) of the regulations says I must use an Equivalence Value of 1.0 even
       though renewable gasoline clearly warrants a higher Equivalence Value. Can I
       submit a petition?

       A:     Yes.  See regulation Section 80.1115(c)(2). However, for renewable fuels
             other than renewable diesel which are made from renewable crudes,
             information on the energy content and/or renewable content may be
             difficult to obtain. This is why we designated the Equivalence Value for
             such fuels as 1.0, and specified that the applicable volumes must be
             measured according to the volume of renewable crude rather than the
             volume of the final product.  In cases where information on the energy
             content and renew able content can be determined precisely, a different
             Equivalence Value may be warranted.

             In addition, regulation Section 80.1126(d)(6) allows a party to petition
             EPA to use the volume of the renewable fuel produced as the basis for
             generating PJNs rather than the volume of the renewable crude used to
             make that product.

1.3     What is the Equivalence Value for E85? Is it 0.85 since its renewable content is
       only 85 percent?

       A:     No. Equivalence Values are generated and apply to renewable fuel at the
             point of production or importation, not at the point of blending.  Thus it is
             denatured ethanol, notE85 (nor El0)  to which the Equivalence Value
             applies. A party blending denatured ethanol into gasoline to produce E85
             may receive  assigned RINs with the denatured ethanol. Since the party is
             producing motor vehicle fuel from the renewable fuel (analogous to an

-------
             oxygenate blender), he will separate the RINsfrom the volume ofethanol
             received and can then retain or transfer those RINs to any other party.

1.4    Do the regulations spell out the petition process to be used to determine
      Equivalence Values for fuels not identified in the rule?

      A:     Yes. The provision is described in regulation Section 80.1115(c).
1.5    I produce motor grade ethanol from a variety of waste streams, including
      industrial waste ethanol and unsellable beverages. Do I have to participate in the
      RFS program and generate RINs? Does my product fit the definition of waste-
      derived ethanol so that I may generate up to 2.5 RINs per gallon of product?

      A:     For purposes of the RFS program, the term "renewable fuel" includes
             cellulosic biomass, waste-derived ethanol, biodiesel (mono-alkyl ester),
             non-ester renewable diesel, and blending components derived from
             renewable fuel (Sec. 80.1101(d)(2)). Further, waste-derived ethanol
             means ethanol derived from either: (1) animal wastes,  including poultry
             fats and poultry wastes, and other waste materials or (2) municipal solid
             waste.  Under this definition, ethanol derived from industrial waste
             ethanol and unsellable beverages is waste-derived ethanol because it is
             derived from  "other waste materials. " Waste-derived ethanol is subject to
             the RFS regulations as a renewable fuel, and therefore ethanol producers
             who produce ethanol from industrial waste sources and/or unsellable
             beverages must register for the RFS program and generate RINs.  Because
             it fits the definition of waste derived ethanol, 2.5 RINs  are generated for
             each gallon of product. See Sees.. 80.1115(b)(l),  80.1126(d)(4).

             The RFS regulations allow cellulosic biomass ethanol  and waste-derived
             ethanol producers and importers to assign between 1.0 and 2.5 RINs per
             gallon of ethanol. See Sec. 80.1126(e)(4).  In the case that the producer
             or importer chooses to assign only 1.0 RINper gallon, they may retain the
             remaining 1.5 RINs per gallon as unassigned RINs, with a K code of 2.
             Such a producer may then sell or otherwise use the separated RINs as the
             producer desires.  Waste-derived ethanol producers, like cellulosic
             biomass ethanol producers, must meet all of the same requirements as
             corn ethanol producers with respect to reporting, recordkeeping, and an
             annual attest engagement. In addition, they must satisfy additional
             requirements related to verifying their feedstock and production processes
             as outlined in Sec. 80.1155.

-------
2.     Generating RINs and assigning them to batches of renewable fuel

2.1     Ethanol is imported on an undenatured basis. Do we assign the RINs to the
       denatured volume or the undenatured volume?

       A:    Denatured. See regulation Sections 80.1101(d) (3) and 80.1115(b)(2).

2.2     We are importers who import ethanol without denaturant, but with the intent to
       use it as motor fuel.  When the RIN is generated, we maintain  ownership of the
       ethanol, but we do not have custody and we  do not add the denaturant.  Would we
       include our company ID number and use the facility number of the denaturing
       facility (i.e. they would have to be registered)?

       A:    The owner of the denaturing facility would not necessarily be a registered
             party under the regulations. The  company and facility IDs of the
             importing party who owns the renewable fuel at the time a RIN is
             generated (based on the volume of renewable fuel with denaturant) are the
             company and facility IDs that must be included in the RIN.  (The owner of
             the renewable fuel should know the volume of the fuel coming out of the
             denaturing facility since it owns and will either sell or use the denatured
             fuel.) The importing company that owns the fuel would need to register
             the facility, typically leased tankage,  with which it has contracted to store
             and denature the renewable fuel (i.e., has custody) as one if its own
             facilities with its own facility ID number. This means that a facility owned
             by a company that simply leases tankage may never be a registered party
             but several registered importers may have a separate facility ID for that
             tankage facility. This scenario would not apply to domestic producers
             because ethanol intended to be used as motor fuel would be denatured at
             the facility where it was produced.

2.3     A refinery can produce non-ester renewable  diesel by processing renewable
       feedstock through a distillate hydrotreater. In this situation, the refinery must
       assign RINs based on the feed volume. I assume the refinery can follow the rules
       for defining a batch (i.e. a batch can be up to the production volume of a month as
       long as the batch total volume is less than 100 million gallons).

       A:    Yes. However,  it is the total number  ofgallon-RINs, not the total volume
             that must be less than  100 million. See regulation Section 80.1126(c).

2.4     When a plant determines the volume of ethanol  for a first and last gallon of a
       RIN, what's the reference point? Gallons at load-out through a metering system
       like Determan Brownie?  (Since this is the point where they're adjusting the
       gallons to 60 degrees F)?

-------
      A:    Renewable fuel producers and importers have flexibility in terms of the
             specific means through which they measure volumes for purposes of
             generating RINs. However, the approach should ensure that gallons are
             neither systematically ignored nor systematically double-counted. Also,
             approaches that provide consistent volumes for both the RFS program and
             other contexts such as reporting to the Energy Information Administration
             are preferred.  To the degree that measuring volumes at load-out through
             a Determan Brownie metering system meets these criteria, it would be
             acceptable.

             Under the regulations, RINs must be generated for a volume of renewable
             fuel by the time that that volume is transferred to another party (at which
             time, the RINs are "assigned" to the renewable fuel pursuant to
             regulation Section 80.1126(e)(2)). Thus the volume measurement used as
             the basis of RIN generation can occur as the renewable fuel is produced,
             as it resides in a tank awaiting transfer from the producer/importer, or as
             it is pumped to a new owner.  The method used must be consistent over
             time for a facility.

2.5   Within the RIN, D = 2 for non-cellulosic biomass ethanol and D = 1 for cellulosic
      biomass ethanol.  How is biodiesel coded?

      A:    All renewable fuels that cannot be categorized as cellulosic biomass
             ethanol should be assigned RINs with a D code value of 2. Thus biodiesel
             would have D = 2.  See regulation Section 80.1125(g).

2.6   Can an ethanol or biodiesel plant keep a RIN?

      A:    In general, producers of renewable fuel must assign all RINs that they
             generate to volumes of renewable fuel and transfer those RINs with the
             renewable fuel to another party. However, there are some exceptions.
             First, producers of cellulosic or waste-derived ethanol can retain RINs
             generated in excess of an Equivalence Value of 1.0 (see regulation Section
             80.1126(e)(4)).  Second, a renewable fuel producer who is also an
             obligated party can retain RINs generated up to the level of their annual
             RVO (see regulation Section 80.1129(b)(6)).  Lastly, producers can
             acquire an unlimited number ofunassignedRINs through the open RIN
             market.

2.7   No Equivalence Value was provided for ETBE.  What value do I use for
      generating RINs for ETBE?

      A:    The RFS program prohibits a party from generating RINs if the renewable
             feedstock used to make the renewable fuel was acquired from another party.
             Any RINs acquired with the renewable feedstock (e.g., ethanol) must be
             assigned to the renewable fuel product (e.g., ETBE) made from that feedstock.

-------
             If the ethanol used to make ETBE does not have RINs associated with it (i.e.
             the RINs have been properly separated prior to receipt of the ethanol by the
             ETBE producer), then the ETBE producer would neither generate RINs for
             the ETBE it producers, nor assign any RINs to that ETBE. Thus there is no
             need for an Equivalence Value for ETBE. See regulation Section
             80.1126(d)(8).

2.8    I will be making ethanol from both cellulosic feedstocks and corn in my plant.
       How do I know what Equivalence Value to use, and how do I assign RINs to
       batches?

       A:    The batches of each type of ethanol (cellulosic or corn) should be
             measured independently and precisely, according to the separate
             processes used to produce them in the plant.  Once separate batch
             numbers are created and RINs are generated, the producer can combine
             the mixed volumes (cellulosic with corn) in a common tank. As product
             leaves the common tank, the producer may assign whatever valid RINs
             they wish to assign that outgoing product.  The total number of RINs that
             could potentially be assigned to product leaving the tank would be the sum
             of the RINs generated for the different types of ethanol added to the tank.
             However, up to  1.5 RINs per gallon of the cellulosic ethanol produced and
             added to the tank may be retained as an unassigned RIN with a K code of
             2. It should be highlighted that due to changes that will result from
             passage of the Energy Independence and Security Act, certain aspects of
             this approach are likely to change in future regulations.

             Alternatively, we have created a regulatory mechanism through which the
             producer may submit a petition to the Agency describing the renewable
             fuel, its feedstock and production process, and the calculation of its
             Equivalence Value.  See regulation Section 80.1115. This petition process
             can be used to identify an appropriate Equivalence Value for mixtures of
             renewable fuels.
2.9    Are RINs generated at the end of the month based on actual quantities for that
       period, or are they established at the beginning of the month based on estimates of
       production that month (i.e.  "x" gallons, and once "x" gallons are exceeded the
       RIN starts over?)

       A:    All RINs represent actual production, not estimates. However, there is no
             need to wait until the end of a month to generate RINs.  Each producer
             and importer should decide what the batch number (the BBBBB code in
             the RIN) will represent. The regulations require only that each batch
             represent no more than the volume produced or imported within a
             calendar month, and less than 100 million gallon-RINs. One party may
             decide to assign each week's production a unique batch number, while

-------
             another may decide to assign each tank full a unique batch number.
             Regardless, gallon-RINs can be generated as volumes are produced and
             transferred.  As more volume of renewable fuel is produced, additional
             gallon-RINs are generated within the same batch, up to the self-imposed
             or regulatory limit for that batch. Then a new batch with a new BBBBB
             code begins.

2.10   If a plant establishes RINs at the beginning of the month and defines it as one
       month's production estimate (e.g. 8 million gallons), what happens if the plant
       produces more than 8 million gallons by the end of the month? Does the plant
       then start issuing a new batch number for the next 8 million gallon RIN? What if
       this happens in the middle of filling a rail car?

       A:    RINs are not generated at the beginning of a month. Rather, gallon-RINs
             must have been generated by the time a volume of renewable fuel is
             transferred from the producer or importer to another party (at which point
             the RINs are assigned to that volume). See regulation Section
             80.1126(e)(2). A producer or importer of renewable fuel can decide on its
             preferred approach of designating batch numbers (the BBBBB code in the
             RIN),  and then put this batch number into all gallon-RINs generated up to
             a calendar month's production or 100 million gallon-RINs, whichever
             comes first.

             If a producer/importer had predefined a specific volume limit (such as 8
             million gallons) for each batch, and this limit was exceeded in the middle
             of filling a rail car, the producer/importer would have two options.  Since
             the 8 million gallon limit is self-imposed, he could simply exceed this limit
             for this particular batch. Alternatively, he could generate a new set of
             gallon-RINs having a new batch number for the volume that exceeded 8
             million gallons. In this latter case, the renewable fuel in the rail car
             would be transferred along with two separate batch-RINs, which differ
             only in the batch number (i.e. the BBBBB code) and the number of gallon-
             RINs they represent.

2.11   Do batch numbers have to be sequential? Do they have to correspond to the
       month that they represent (i.e. 1  - 12)?

       A:    Batch numbers need not be sequential and need not represent a full
             month.  They need only be unique within a calendar year. Each producer
             or importer of renewable fuel can define a batch in whatever way it
             chooses,  so long as each batch represents less than  100 million gallon-
             RINs and no more than one calendar month's production. See regulation
             Sections 80.1125(e) and 80.1126(c). Examples of permissible batch
             numbering schemes include individual tank fulls, calendar day production,
             weekly production, and volume sold to each customer each month.

-------
2.12   When the program starts, will renewable fuels in the distribution system on
       September 1, 2007 be valid for RFS compliance purposes?

       A:    In some cases, yes.  Renewable fuels that are valid for RFS compliance
             purposes are those for which RINs have been generated. Under
             regulation Sections 80.1104 and 80.1126(d)(l), RINs must be generated to
             represent renewable fuels that are produced or imported on or after
             September 1, 2007. However,  our regulations do not define the point at
             which production occurs.  It could be the point of physical production,
             loading into a tank, or transfer to another party. Thus, under regulation
             Section 80.1126(d)(2), RINs can also be generated for renewable fuel that
             a producer or importer  owns on September 1, 2007 even if that renewable
             fuel had been physically produced or imported prior to September 1.
             Since some renewable fuel will be in the distribution system while
             remaining under the ownership of a producer or importer on September 1,
             2007, it may be assigned RINs even though it has already physically left
             the originating production or importation facility. In such cases,
             renewable fuel in the distribution system on September 1, 2007 may have
             assigned RINs.

             Parties other than renewable fuel producers and importers are not
             allowed to generate RINs at any time (including for renewable fuel in the
             distribution system  on September 1, 2007).  Renewable fuel producers and
             importers may generate RINs for renewable fuel they own on September 1,
             2007 that was produced or imported earlier, and must generate RINs for
             renewable fuel produced or imported on or after September 1, 2007.

2.13   Can a producer aggregate multiple shipments into a single batch up to a threshold
       quantity as long as the batch is  within one calendar month?

       A:    Yes. In the context of generating RINs and specifying the BBBBB code,
             producers and importers have  the option to define a batch as being
             comprised of several discreet shipments within a calendar month, so long
             as the total number of gallon-RINs assigned a unique batch number is less
             than 100 million. See regulation Sections 80.1125(e) and 80.1126(c).

2.14   When is a RIN generated for ethanol that is imported into the U. S.?

       A:    Ethanol imported for use as motor vehicle fuel would typically be
             downloaded from a ship into on-shore tankage and then denatured.
             (Ethanol shipped to the  United States from other countries is not typically
             denatured prior to or during shipment.)  Importers should generate RINs
             for imported ethanol when the  denaturant is added at the off-loading
             tankage. Thus, the facility number used to create these RINs would be the
             tankage facility where the denaturant is added. See also question 2.2.

-------
2.15   Regulation Section 80.1126(d)(l), which says "must," seems in conflict with
       Section 80.1126(d)(2) which says "may". Is the correct reading that any volume
       of renewable fuel that leaves a producer's gate on or after 9/1/07 MUST have
       RINs assigned?

       A:    Renewable fuel producers and importers may generate RINs for
             renewable fuel they own on September 1, 2007 that was produced or
             imported earlier, and must generate RINs for renewable fuel produced or
             imported on or after September 1, 2007. Thus at the beginning of the
             program, it is possible that some volumes of renewable fuel being
             transferred by a renewable fuel producer or importer may not have
             assigned RINs. However, this will not be the case in the longer term,
             since all renewable fuel imported or produced must have assigned RINs.

2.16   What's the difference between generating a RIN and assigning it?

       A:    Generating a RIN refers to the process of creating a new RIN to represent
             a particular type and volume of renewable fuel.  See regulation Section
             80.1126(d). Assignment occurs when the producer or importer of the
             renewable fuel transfers a RIN to another party along with a volume of
             renewable fuel. See regulation Section 80.1126(e).

             Note that the regulations do not specify the point when generation of RINs
             must occur. Under regulation Section 80.1126(e)(2), it is only at the point
             when a volume of renewable fuel leaves the production or importation
             facility where it originated that RINs must have been generated for,
             assigned to, and transferred with that volume. Since the EPA does not
             specifically define the point of production or importation, a producer can
             generate RINs as the renewable is being physically produced, as it sits in
             a tank awaiting transfer to another party, or even while the renewable fuel
             is  being transferred to another party.

2.17   Assume a plant decides to define a batch as 10 million gallons.  He starts the
       batch on September 1  and hits the 10 million gallon mark on September 20.  He
       then starts the second batch, but doesn't hit the 10 million gallon mark until
       October 10. Since each batch is less than 31 day's worth of production, is this
       OK?

       A:    No. Abatchof renewable fuel must meet both of the following criteria: 1)
             a batch must represent less than 100,000,000 gallon-RINS, and 2) a batch
             must represent no more than one calendar month's worth of production.
             Thus a batch cannot represent production that spans two calendar
             months, such as September and October. Even though the producer
             decides to define a batch as 10 million gallons, if the end of a calendar
             month is reached before the 10 million gallon mark is reached, a new
             batch must be star ted at the beginning of the next calendar month.

2.18   All I do is produce corn ethanol and sell it all to X Company, which is an ethanol
       marketer. Do I have to do anything, or can X Company generate the RINs for
       me?

       A:     Each producer of renewable fuel is responsible for generating the RINs
             that represent that renewable fuel. This function cannot be delegated or
             assigned to any other party, including a party to whom a producer sells its
             product.

2.19   What happens to gallons of ethanol that are in the system August 31 without
       assigned RINs?

       A:     The answer depends on who holds those gallons of ethanol. Only
             producers or importers of renewable fuel can generate RINs for any
             renewable fuel they own on September 1, 2007.  See regulation section
             80.1126(d)(2). Any volumes of renewable fuel in the distribution system
             as of September 1, 2007 for which RINs were not generated by a producer
             or importer, or which were not owned by a producer or importer on
             September 1, 2007, will not have assigned RINs. Under the regulations, a
             marketer can transfer a volume of renewable fuel without associated RINs
             so long as the end-of-quarter check of RINs held and volumes held has
             been met.  See regulation section 80.1128(a) (5).

2.20   The following is a two-part question:
             a.     We are a petroleum refiner and recognize that we are an obligated
                    party under the regulation. We are considering importing ethanol
                    that has not been denatured.  We will hold title to the un-denatured
                    ethanol. Title and custody will pass to another party who will
                    denature the ethanol and transfer title back to us. We will sell it
                    for use as a motor fuel. Are we an importer of renewable fuel
                    under the RFS program?

                    A:     Un-denatured ethanol is not a renewable fuel. See
                           80.1101(d)(3).  Under the described scenario, the party to
                           whom custody is transferred and who denatures the ethanol
                           would be producer of the renewable fuel.

             b.     How would RINs be generated?

                    A:     Under the described scenario, RINs would be generated by
                           the party who denatures the ethanol and produces the
                           renewable fuel.  See 80.1126(d). If the petroleum refiner
                           wishes to generate RINs, then the petroleum refiner would

-------
                           have to keep title to the ethanol throughout the described
                           transaction.
2.21   We are a marketer with an inventory of denatured ethanol stored at various
       commercial facilities and terminals.  We do not produce or import ethanol. We
       are registered as a party who owns RINs. On September 1, 2007, do we assign
       RINs to our stored inventory?

       A:    No.  Only a producer or importer of renewable fuel may generate RINs for
             volumes of renewable fuel that it owns on September 1, 2007. See
             80.1126(d)(2).
2.22   Section 80.1151(b)(3)(vii) requires retention of additional information related to
       the details of RIN generation. What does this mean?
      A:    Companies vary in their internal recordkeepingpractices and not all
             similar records will take identical form.  Therefore, in several places in
             the recordkeeping section (80.1151) we have required that "additional"
             information be retained. We certainly do not wish to dictate how a
             company keeps each and every record, as this would present an
             unnecessary compliance burden.  However, since one reason for retaining
             company records is to be able to produce them should an enforcement
             question arise, it is in a company's best interest to retain "additional
             information" that may fully explain the details of RIN generation as
             reported to EPA.  These records must be presented to EPA upon request.

2.23  We are a producer of ethanol. If we have 10,000 gallons in inventory on
      September 1, 2007 and 25,000 came from our production facility A, 25,000 came
      from our production facility B, and the other 50,000 we own but received from
      various other producers, how do we assign RINs to the other 50,000?

      A:    As an ethanol producer or importer, you may assign RINs to the product
             you own on September 1, 2007. As far as how  to handle the facility
             identification number fields in the RIN, you will want to consistently
             document and assign the other 50,000 RINs to  one of your registered
             facilities as of September 1, 2007.
2.24   We are a producer of ethanol. We have ownership of renewable fuel that is in
       transit on September 1, 2007. How do we assign a RIN to that fuel?
                                       10

-------
       A:    As long as you actually own the fuel on September 1, 2007, it does not
             matter that it is in transit. As a producer, you may assign RINs to product
             you own on September 1, 2007. You may assign the RINs for ethanol that
             you own but that is in transit to one of your registered facilities.
2.25   Prior to the RFS rule, industry has used an equation for standardization of ethanol
       volumes that carries the correction factor out to 5 digits rather than 7 digits as in
       the formula given in the RFS rule at 80.1126(d)(7)(i).  Will use of the equation
       currently in practice suffice for purposes of compliance with the RFS rule?

       A:     Because the difference between the Jive-digit and seven-digit factors is
              extremely small, regulated parties may find that it makes no practical
              difference whether they use the  shorter factor for batches of a certain
              size.   If it makes no difference in compliance calculations, you may wish
              to use the shorter factor for convenience.  In any enforcement
              proceedings, however, EPA will use the specified seven-digit factor to
              verify compliance.  We believe that using the 5 digit factor (0.00063)
              rather than  the 7 digit factor in the regulations (0.0006301) will not result
              in an substantial difference it the number of whole gallons assigned to a
              batch of renewable fuel, and,  therefore, may be used to determine the
              volume of a batch under section 80.1126(d)(7).
                                        11

3.     Transferring RINs with renewable fuel

3.1     The final rule on page 23909 (Federal Register, volume 72) states that any non-
       obligated party that takes ownership of the renewable fuel with RINs will be
       required to transfer those RINs with a volume of renewable fuel. Does this refer
       to oxygenate blenders?

       A:     No, as long as the blender actually blends the renewable fuel into gasoline
             or diesel.  In that case, the blender would be required to separate the
             assigned RINs from the blended renew able fuel, and could then transfer
             the RINs to any party without simultaneously transferring a volume of
             renewable fuel. See regulation Sections 80.1128(a)(3) and 80.1129(b)(2).

3.2     If an oxygenate blender must transfer RINs with a volume of renewable fuel, who
       are they transferring to, if they are the final/end-user?

       A:     If any oxygenate blender blends renewable fuel into gasoline or diesel, he
             is no longer required to transfer RINs and renewable fuel together.

3.3     Do third party marketers like X Company need to track RINs from the ethanol
       plant to the buyer?

       A:     IfX Company takes ownership of ethanol along with assigned RINs, it
             would be required to register with the EPA and would be subject to the
             recordkeeping, reporting, product transfer document and attest
             engagement requirements of regulation Sections 80.1151(d), 80.1152(c),
             80/1153 and 80.1164(c).  The tracking required under the RFS rule
             involves only transfers of title (ownership), not transfers of custody.  IfX
             Company never takes ownership of ethanol with assigned RINs and does
             not participate in other ways in the RFS program (for example, through
             the purchase and sale ofunassignedRINs),  it would not be required to
             register with, or report to, EPA under the RFS program.

3.4     Will ethanol and biodiesel plants have to track the RIN all the way to the refiner,
       or just to the next owner of the renewable fuel?

       A:     Refer to the response to Question 3.3. Each party that owns assigned or
             unassigned RINs, including an ethanol or biodiesel production plant, is
             required only to keep records of and report transfers of ownership of those
             RINs its receives and that is passes to the next owner.  See sections
             80.1151 and 80.1152 of the  regulation.

3.5     The RIN is too long to fit onto my bill of lading.  What are my options?
                                       12

-------
      A:    An assignedRIN must appear in its entirety on product transfer
             documents (PTDs) identifying a transfer of ownership of a volume of
             renewable fuel. Substitute codes are not permitted. See regulation
             Section 80.1153.  (In general PTDs would not include bills-of-lading,
             which are used for transfers of custody rather than transfers of
             ownership.) However, the PTD transferring the PJNs can be a separate
             and parallel PTD from that used to transfer the renewable fuel to which
             those PJNs are assigned.  In this case, the PTD transferring the renewable
             fuel must include the number of gallon-PJNs being transferred and a
             unique reference to the PTD which is transferring the assigned PJNs, but
             need not list the actual PJNs. See regulation Section 80.1153(a)(5)(ii).
             PTDs can be electronic, including computer spreadsheets.

3.6   How do owners of the ethanol account for product samples taken  at the plant and
      downstream relative to RINs? Likewise, how is  standard product shrinkage (i.e.
      when ethanol is transferred to a terminal) handled relative to  RINs?

      A:    In general, the PJNs associated with small volumes removed for sampling
             and testing, or lost due to evaporation,  leakage,  or metering imprecision,
             remain valid for RFS compliance purposes. Small volume losses can be
             accommodated through the regulatory provision which allows up to 2.5
             gallon-PJNs to be transferred with each gallon of renewable fuel. See
             regulation Section 80.1128(a)(4).  For larger volumes losses resulting
             from spills or other accidents, a provision exists for retiring the associated
             RINs.  See regulation Section 80.1132.

3.7   How does a marketer  split RINs that go to downstream buyers (i.e. next owners
      like a refiner)?

      A:    Parties such as marketers that are required to transfer assigned PJNs with
             renewable fuel are not required to align the number of gallon-PJNs
             transferred with  the number of gallons transferred for every transaction.
             Rather, the regulations require only that  the number of assigned gallon-
             PJNs (with a K code of 1) transferred with each gallon of renewable fuel
             be no more than 2.5.  See regulation Section 80.1128 (a) (4) and preamble
             discussion at page 23939, column  3. Within this limit, a marketer is free
             to allocate gallon-RINs to volumes of renewable fuel  in whatever way he
             chooses, so long as an end-of-quarter check on the balance of RINs versus
             renewable fuel in inventory is met.  See regulation Section 80.1128(a)(5).

3.8   Does regulation Section 80.1128(a)(4) allow a marketer to change the K code
      from 1 to 2 and then not transfer the RIN with the renewable  fuel  as long as he
      sells the RINs to anyone by the end of the quarter?

      A:    Marketers who buy and sell renewable fuel without blending it into
             gasoline or diesel cannot separate RINs from volumes, and thus cannot
                                       13

-------
             change the K code from 1 to 2.  All conditions under which a party can
             separate RINsfrom volumes are set forth in regulation Section
             80.1129(b).  However, a marketer can indeed decide not to transfer a
             particular BIN with a volume of renewable fuel so long as the end-of-
             quarter check described in regulation Section 80.1128(a)(5) is fulfilled.

3.9    Will non-obligated parties that can hold title to RINs be required to balance them
       each quarter?

       A:    Every party that owns assigned RINs must comply with the end-of-quarter
             check described in regulation Section 80.1128(b)(5).  This provision
             ensures that RINs must be transferred with renewable fuel as renewable
             fuel moves through the distribution system.  However, this provision
             applies to assigned RINs only (with a K code of 1).  Any party can own
             any number ofunassignedRINs (with a K code of 2) and unassigned RINs
             are not subject to any end-of-quarter check.

3.10   What happens if a marketer sells a batch with one RIN to two different refiners?
       Can he divide the RIN?  If so, how?

       A:    The basic unit of compliance in the RFS program is the gallon-RIN.
             However, for shorthand we allow multiple sequential gallon-RINs to be
             represented by a single batch-RIN through the appropriate designation of
             the start (SSSSSSSS) and end (EEEEEEEE) codes in the RIN.  As physical
             volumes of renewable fuel are split or merged,  the assigned batch-RINs
             can likewise be split or merged in various ways, with the primary
             restriction being that no more than 2.5 assigned RINs can be transferred
             with every physical gallon of renewable fuel (see regulation Section
             80.1128(a) (4)). See also question 3.7.

3.11   How can a marketer transfer RINs with a K code of 1 and fulfill the requirement
       that "No person may transfer a RIN that has a K code of 1 without transferring an
       appropriate volume of renewable fuel to the same person on the same day"?

       A:    A party may transfer any volume of renewable fuel to  any other party
             without simultaneously transferring any assigned RINs to that same party.
             However,  assigned RINs can only be transferred to another party in
             association with the transfer of a volume of renewable fuel. Under
             regulation Section 80.1128(a)(4), the ratio of assigned RINs transferred to
             gallons transferred can be anywhere between zero and 2.5.

3.12   The following is a two-part question:
             a.     We are a wholesaler of El 00 and B100. We do not do any
                    blending. We purchase and sell El 00 and B100 and sell it to
                                       14

-------
                    anyone who needs it. What in the RIN code must be changed to
                    document the change of ownership?

                    A:    Nothing changes in the RIN code to document a change of
                          ownership.

             b.     What would the wholesaler put on his PTDs when he transfers title
                    to another party?

                    A:    Section 80.1153 describes the requirements for PTDs,
                          which generally include the name and address of the
                          transferor and transferee, the company registration number
                          of each, the volume of renewable fuel being transferred, the
                          date of the transfer, and information about any assigned
                          RINs.

3.13   The following is a two part question. We are a marketer of ethanol products.
       Sometimes personnel at ethanol plants make mistakes as to the number of gallons
       being loaded or produced. How do we "recall" erroneous RINs if:

             a. the number of gallons we receive exceeds the number of RINs?

                    A:    PTD documents may be corrected to reflect the appropriate
                          volume associated with the volume received.  The
                          additional volume with assigned RINs may be addressed
                          with a second PTD.
             b. the number of RINs exceeds the number of gallons we receive?

                   A:    The parties (producers) selling ethanol to you have an
                          obligation to transfer appropriate RINs to you. A producer
                          who is also a marketer may assign up to 2.5 RINs per
                          gallon of renewable fuel. A producer who is not a marketer
                          may only assign RINs up to the renewable equivalence
                          value (EV). If a company receives an excess number of
                          RINs assigned to a gallon, then the producer would be in
                          violation.  To rectify this, a producer may ask a recipient to
                          retire the excess RINs. There is a retirement code on the
                          reporting form for RINs generated in error and that code
                          should be used.

3.14   The following is a two part question.

             a.    We would describe ourselves as an ethanol marketer, but we
                   import gasoline into one of the 48 contiguous United States. Does
                                       15

-------
                    this make us an obligated party and, as an obligated party, are we
                    able to separate RINs?

                    A:     If a party is an importer of gasoline into the 48 contiguous
                           United States, then that party is an obligated party. Section
                           80.1129(b)(6) allows an obligated party to separate RINs
                           they generated from volumes of renewable fuel, if the
                           number of gallon-RINs separated is less than or equal to
                           the annual RVO.  This section applies to assigned RINs
                           generated by the obligated party through the production or
                           importation of renewable fuel. Section 80.1129(b)(6) does
                           not cover marketers who buy renewable fuel with assigned
                           RINs since these RINs were not generated by the obligated
                           party. Therefore, an obligated party who also markets
                           renewable fuel, must separate assigned RINs, not
                           generated by the obligated party, from any renewable fuel
                           acquired as stated in Section 80.1129(b) (1). The  obligated
                           party may use the separated RINs or transfer them.

                           However, if an obligated party is a marketer and is also an
                           importer (or producer) of renewable fuel, per section
                           80.1129(b)(6), they may separate RINs which they generate
                           when importing or producing the renewable fuel,  only up to
                           the associated RVO.

             b.     If the answer to part a. is "no," may I use my minority ownership
                    in a cooperative refinery to be considered an  obligated party, able
                    to separate RINs?

                    A:     With regard to the second part of the  question,  the answer
                           is "no. " Typically, obligated parties are registered on a
                           corporate level. Therefore, the obligated party would be
                           the refinery on a corporate level rather than on an
                           individual shareholder level.
3.15   Are companies that are both producers and marketers of ethanol subj ect to the
       RIN transfer requirements of 40 CFR 80.1128(a)(5), or the more stringent
       requirements of 80.1128(a)(6)? These issues have surfaced because a number of
       independent gasoline marketers who blend ethanol as part of their normal
       business practices have indicated that they would rather not take ownership of
       RINs and not participate in the RFS program.  Presumably,  if such parties never
       take ownership of RINs, they would not have to register as regulated parties with
       the Environmental Protection Agency (EPA) as required under the RFS
       regulations and would, therefore, not be subject to RFS reporting requirements or
       to other enforcement-related requirements of the regulations, such as attest
                                       16

-------
engagements (audits) and record-keeping requirements. We would like
confirmation from EPA regarding this interpretation of the regulations, and also
seek clarification as to whether companies that both produce and market ethanol
are able to transfer ethanol with zero assigned RINs in the same manner as
companies that are only involved in marketing operations.

A:     Under section 80.1128(a) of the RFS regulations, a party owning ethanol
       with assigned RINs cannot, (unless they are an obligated party, renewable
       fuel exporter, a per son that converts renewable fuel into motor vehicle
       fuel, or a cellulosic ethanol producer), transfer RINs without transferring
       a volume of ethanol.  This section also places a maximum number of RINs
       (2.5) that can be transferred with any gallon of renewable.  The
       regulations, however, do not prohibit the transfer of ethanol from a
       marketer to another party, for example, an independent gasoline marketer,
       with no RINs attached.  In other words, a marketer can transfer ethanol
       with anywhere from zero to 2.5 RINs attached to each gallon of renewable
       fuel.  If a transaction is made where the marketer sells ethanol without
       RINs attached, the party purchasing the ethanol need not be registered
       with EPA as a regulated party if that party never owns any RINs during
       the course of the reporting period.  Therefore, if an independent gasoline
       marketer who blends ethanol purchases ethanol without RINs from an
       ethanol marketer,  and never owns RINs during a reporting period, then
       that gasoline marketer/blender need not be registered with EPA and need
       not comply with the reporting requirements and other enforcement
       requirements applicable to RIN owners, such as attest engagements
       (audits) and recordkeeping requirements as outlined in the regulations.

       It is important to note however, that ethanol marketers are responsible to
       assure that RINs will be passed along to ethanol purchasers over the
       course  of a reporting period, typically one quarter of a year. Any party
       owning ethanol with assigned RINs and covered under section 80.1128(a),
       typically a marketer of ethanol, must meet the RIN inventory requirements
       at section 80.1128(a)(5). These essentially oblige the ethanol marketer to
       transfer all RINs acquired during a quarter with an associated renew able
       fuel volume, except for the RINs associated with the volume which is held
       in the marketer's inventory at the end of the quarter. In other words, all
       RINs acquired by the marketer must be transferred to some purchaser
       during the quarter, except for those RINs associated with end-of-quarter
       inventory.
       Unlike marketers,  ethanol producers have certain additional
       responsibilities regarding the transfer of RINs with product. Under
       section 80.1128(a)(6), producers (and importers) of renewable fuels must
       transfer ownership of the RINs associated with a volume of renewable fuel
       whenever that renewable fuel is sold. Accordingly, it is not possible for an
       ethanol producer to transfer ethanol without associated RINs, and all
                                 17

-------
             parties to whom they transfer ethanol must be registered with EPA to
             participate in the RFSprogram.

             You asked for clarification regarding the RIN-transfer requirements that
             apply to a company that both produces and markets ethanol. EPA
             believes that the RFS regulations are ambiguous in this regard. In
             interpreting the regulations at this time, EPA is mindful of both the
             original purpose of the more restrictive RIN-transfer requirements
             applicable  to producers, which was to minimize the possibility of short-
             term hoarding, and the benefits to marketers and distributors of ethanol
             that is reflected in the more flexible requirements of 40 CFR
             80.1128(a)(5). See 72 Fed. Reg. 23939 - 23942. (May 1, 2007), EPA is
             also cognizant of the concerns of some gasoline marketers who may wish
             to purchase ethanol without associated RINs, so as to avoid the costs
             associated with the registration, reporting and attest engagement
             requirements of the RFS program. Finally, EPA 's wish throughout the
             implementation of the RFS program has been to minimize disruption of
             currently-established business patterns. Accordingly, EPA does not wish
             its program to act as a disincentive to firms that wish to both produce and
             market ethanol. Balancing these various concerns, EPA is interpreting
             the RFS regulations to allow any producer that is also in business as an
             ethanol marketer, to utilize the more flexible RIN-transfer requirements of
             40 CFR 80.1128(a)(5)for all of the ethanol that they sell.   In order to
             qualify for  this treatment, the producer must market ethanol of other
             producers as well as its own. Thus, producers who only market and sell
             the ethanol that they produce must comply with the RIN transfer
             requirements of 40 CFR 80.1128(a)(6).  Producers who market and sell
             their own ethanol and that of others must comply with the RIN-transfer
             requirements of 40 CFR 80.1128(a) (5).

             Given our view of the regulations as explained above, we believe there is
             more than sufficient flexibility for gasoline marketer/blenders who do not
             want to participate in the RFS program to purchase ethanol without RINs.
             Such companies would therefore not have to participate in the
             registration/reporting requirements and other enforcement requirements
             of the RFS program.  EPA also recognizes that there are many gasoline
             marketers that blend ethanol who are very enthusiastic about
             participating in the RFS program. Nothing in this clarification of the
             regulations changes their ability to participate now or in the future.

3.16   In the discussion in the Preamble regarding the requirements for owners of
       facilities that claim to have produced cellulosic ethanol under the 90 percent
       displacement provision, there is a reference to Section III.D.S.e. I have been
       unable to locate this paragraph in the Preamble. Can you direct me toward this
       paragraph or more specifically to the information referenced?
                                       18

-------
       A:     The reference is a typographical error. All relevant discussion appears in
             III(B)(l)(b) of the Preamble, "Ethanol Made from Any Feedstock in
             Facilities Using Waste Material to Displace 90 Percent of Normal Fossil
             Fuel Use, " which starts at 72 FR 21916.

3.17   If I am registered for the RFS program, do I have to receive RINs with the
       renewable fuel I purchase?

       A:    Being registered for the RFS program does not mean that a party must
             receive RINs with the renewable fuel they purchase. Being registered for
             the RFS program means that a party is eligible under the regulations to
             receive RINs. The regulations do not require registered purchasers of
             renewable fuel to purchase such fuel either with or without RINs attached.
             On the other hand,  a party that has not registered for the RFS program is
             prohibited from taking ownership of renewable fuel with attached RINs.

4.     Separating RINs from renewable fuel

4.1     Does blending biodiesel into agricultural diesel (or other nonroad diesel such as
       NRLM diesel) allow the RIN to be separated?

       A:    EPA believes that most fuel that can be used as motor vehicle fuel and
             which otherwise meets the definition of "renewable fuel" (such as
             biodiesel and ethanol) will ultimately be used as motor vehicle fuel.
              Therefore, producers of such products can assume  that they meet the
             definition of "renewable fuel" and can assign RINs to them without
             tracking their ultimate use.

             However, if fuel with assigned RINs is actually blended into gasoline or
             diesel that is known to be destined for use in a  nonroad application such
             as agricultural equipment, the presumption that led the fuel producer to
             assign RINs to the product is no longer valid.  Such fuel cannot be
             considered a motor vehicle fuel and thus is not in fact a "renewable fuel"
             that is valid for RFS compliance purposes.  In such cases, the blender
             should treat the RINs associated with the blended fuel in the same way as
             for fuel with assigned RINs that is used in a heater or boiler (see question
             4.2).  See also preamble Section III.B.I and Summary and Analysis of
             Comments Sections 3.1.2 and 3.1.4.

4.2     If renewable  fuel is produced (or imported) and sold as motor vehicle fuel, what
       happens if it is actually used in a heater or boiler? What if, instead of a heater or
       boiler, the fuel is actually used in a non-road vehicle?
       A:    Renewable fuel is defined as "motor vehicle fuel" and does not include
             fuel used in heaters and boilers or in non-road vehicles. However, due to
                                       19

-------
             the operation of reasonable presumptions, RINs may be generated for fuel
             that is ultimately used in a heater, boiler or non-road vehicle, and use of
             those RINs for compliance purposes depends on the circumstances.

             If a producer or importer transfers fuel to another party with the intent or
             expectation that it will be used in a heater, boiler or non-road vehicle, the
             producer or importer cannot generate RINs for that volume.  Likewise,
             fuel used onsite in a boiler or heater by a renewable fuel producer or
             importer is not a renewable fuel in the context of the RFS program, and
             thus no RINs can be generated for that volume.

             However, if a producer or importer transfers fuel to another party with the
             intent or expectation that it will be used as a motor vehicle fuel, and such
             fuel otherwise meets the definition of "renewable fuel, " RINs will
             legitimately be generated to represent that volume. Nevertheless, it is
             possible that the fuel would subsequently be used in a heater, boiler, or
             non-road vehicle. Since such fuel is not considered motor vehicle fuel or,
             therefore, renewable fuel, in general the RINs generated to represent that
             fuel should be not be used for RFS compliance purposes. If the party who
             used the renewable fuel in a heater, boiler or non-road vehicle did not
             receive RINs with the renewable fuel (for example, if RINs were separated
             from the  fuel upstream), we would not require any further action from the
             party who used the renewable fuel in a heater or boiler and the separated
             RINs could be used for compliance purposes by the upstream party that
             separated them or to whom they were transferred, provided that they were
             not aware that the fuel would ultimately be used in a heater, boiler or non-
             road vehicle. However, if the party that used the fuel in a heater, boiler or
             non-road vehicle received assigned RINs with that fuel, the party cannot
             use the RINs for compliance purposes or transfer those RINs to any other
             party. Such RINs would be considered "invalid" under regulation
             Sections 80.1131(a)(6) and80.1101(d)(5) and should be retired according
             to80.1129(e).

4.3    Can an oxygenate blender separate RINs from batches of renewable fuel and
       participate in trading?

       A:    Yes, if the blender actually blends renewable fuel that it owns into
             gasoline  or diesel. Separated RINs then become unassigned RINs that can
             be traded without renewable fuel.  See regulation Section 80.1129(b)(2).
             See also questions 3.1 and 3.2.

4.4    A refinery can produce non-ester renewable diesel by processing renewable
       feedstock through a distillate hydrotreater. In this situation, the refinery must
       assign RINs based on the feed volume.  The refiner is then both an obligated party
       and a renewable fuel producer and as such can separate the RIN immediately. Is
       this correct?
                                       20

-------
      A:    Yes, since under regulation Section 80.1129(b)(l) all obligated parties
             must separate RINsfrom batches they own.  However, an obligated party
             can only separate RINs that it generates from volumes of renewable fuel if
             the number of gallon-RINs separated is less than or equal to its annual
             RVO. See regulation Section 80.1129(b)(6).

4.5   Do we have to keep some type of spreadsheet listing the assigned RINs and the
      "flipping" of the K code to designate that we stripped them?

      A:    Under the regulations at Section 80.1151, a party that separates RINs
             from volumes of renewable fuel is subject to certain recordkeeping
             requirements.  There is no specific recordkeeping requirement to show the
             timing or conditions under which the K code for a RINwas changed from
             1 to 2.  However, RINs received with a K code of 1 that were separated by
             a party should be reported with K codes of 2. The format of records (e.g.
             spreadsheets versus paper records) is left to the discretion of the party.

4.6   Since they receive 1.5 RINs per gallon, can a biodiesel plant separate the RIN
      from a physical gallon?

      A:    No. Producers and importers of renewable fuel must assign all RINs
             generated to renewable fuel, and transfer those RINs when transferring
             volumes of renewable fuel to another party.  See section 80.1126(e)(l) of
             the regulation.  There are limited exceptions to this rule that do not apply
             to biodiesel, including the exception for producers or importers of
             cellulosic biomass ethanol or waste-derived ethanol. See section
             80.1126(e)(4) and the response to Question 2.6.

4.7   I am a small refiner who is exempt from meeting the standard.  Am I allowed to
      separate RINs from batches of renewable fuel?

      A:    Exempt small refiners and refineries are not obligated parties. As a
             result, they cannot separate assigned RINs from volumes of renewable fuel
             upon ownership of the renewable fuel. However,  if the exempt small
             refiner/refinery blends renewable fuel into gasoline or diesel,  they are
             operating as a blender andean separate the RINs associated with the
             renewable fuel added to the blended product. A small refiner/refinery that
             waives its exemption becomes an obligated party and must also separate
             assigned RINs from volumes of renewable fuel upon ownership.

4.8   If I import ethanol for someone else,  and they blend the ethanol into gasoline, do I
      get the RINs?

      A:    In general, all rights and responsibilities under the RFSprogram that are
             tied to renewable fuel are based on ownership of fuel, not custody. Thus if
                                       21

-------
             you own the ethanol even though another party blends it into gasoline,
             then you would separate the RINs associated with the ethanol and would
             retain or transfer them to another party depending on the situation. If,
             however, your involvement was only to physically supply the ethanol while
             never taking ownership of it, then you would not own the RINs and could
             not separate them upon blending - that would be the responsibility of the
             owner of the ethanol.

4.9    At our terminal, we transfer ownership of ethanol to our customers
       simultaneously with blending that ethanol into gasoline. Who owns the RINs?

       A:    A RIN assigned to a volume of renewable fuel is separated by the party
             that owns that volume of renewable fuel at the time of blending. If a
             downstream customer is the owner of the volume of renewable fuel when it
             is blended into gasoline or diesel, he will own the separated RINs and be
             subject to all the  registration, recordkeeping, and reporting requirements.
             In the case of a blender and a downstream customer who might both lay
             claim to the right to separate any assigned RINs, these two parties would
             need to  come to agreement between themselves regarding which party will
             own the separated RINs.

4.10   Are refiners required to separate RINs from renewable fuel?  If a refiner doesn't
       want the RINs,  why can't he just let the blender have them?

       A:    Obligated parties are required to separate a RIN from a volume of
             renewable fuel if they take ownership of that volume.  See regulation
             Section  80.1129(b)(l) and the  limited exception in regulation Section
             80.1129(b)(6). The requirement to separate RINs, rather than merely
             giving obligated parties the right to separate RINs, is intended to promote
             the availability of RINs on the  open RIN market. Given that most ethanol
             is consumed in the midwest, the program is intended to promote access to
             RINs by obligated parties elsewhere that may lack access to renewable
             fuel.

             An obligated party that separates a RIN from a volume of renewable fuel
             has the option of transferring that RIN to a blender in parallel with a
             transfer of renewable fuel.  However, in this case, the RIN would be an
             unassigned RIN with a K code of 2, and would be transferred on a PTD
             separate and independent from that used to transfer the renewable fuel.

4.11   I am a marketer and a blender. If I receive 10,000 RINs with 10,000 gallons of
       ethanol that I buy from a producer, can I sell 5000 gallons without RINs and
       blend 5000 gallons but, in essence, give (from me as a marketer) all 10,000 RINs
       to me (as a blender)?
                                       22

-------
      A:    Yes, under section 80.1128(a)(4) of the regulation, you may transfer
             anywhere from zero to 2.5 assigned RINs with each gallon of renewable
             fuel transferred to another party.  We interpret the regulations to also
             allow a party that is both a marketer and a blender of renewable fuel to
             blend renewable fuel with zero to 2.5 RINs per gallon.  Therefore,
             referring to your example, you may transfer 5000 gallons of renewable
             fuels to others with zero RINs. You may also blend 5000 gallons of
             renewable fuel with 2.5 assigned RINs per gallon.  Upon blending the
             renewable fuel, the assigned RINs must, pursuant to section
             80.1129(b)(2), be separated and may be traded separately. At the end of
             the quarter, you will have met your inventory obligations under section
             80.1128(a)(5), since all the assigned RINs associated with the original
             10,000 gallons will have become separated, and you will own no more
             assigned RINs than your renewable fuel inventory (which is zero in your
             example).
4.12   If a marketer purchases E100 or B100 and becomes the blender, does he retain the
       RIN?  Can that marketer trade those RINs on the open market? What other
       purpose would those RINs serve the marketer if they cannot be traded?

       A:    A party that converts renewable fuel such as B100 or El 00 (which in
             reality will be E95 due to the presence of a denaturant) into motor vehicle
             fuel through blending with conventional gasoline or diesel must separate
             the RINs associated with the renewable fuel.  See regulation Section
             80.1129(b)(2). The blender must change the K code in the RINs from 1 to
             2 to re-designate the RINs as unassigned RINs which can be freely traded
             without renewable fuel.

4.13   Under regulation at Section 80.1129(b)(6), if an obligated party generates some
       RINs, his RVO determines the maximum number of self-generated RINs that he
       can separate. However, the RVO isn't determined until the end of the year while
       the separation of RINs occurs throughout the year. Will EPA consider it a
       violation if an obligated party separates too many self-generated RINs because he
       overestimated his RVO in the middle of a year?

       A:    Yes. Obligated parties should take into account the uncertainty in RVO
             estimates prior to the endof the year.  However, if an unforeseen
             disruption to gasoline production results in a refiner's estimated RVO
             being significantly different from its actual RVO, EPA may consider
             extenuating circumstances in exercising enforcement discretion.

4.14   If a company imports gasoline into the 48 contiguous United States, then it is an
       obligated party.  If the company also imports renewable fuel (e.g. ethanol), then it
       generates RINs. For purposes of this question, assume that the company separates
       RINs by blending the ethanol into its own imported gasoline.  The company can
                                       23

-------
       only separate RINs that it generates up to the level of its RVO. Assuming the
       company imports much more ethanol than gasoline, its RVO will be much smaller
       than the number of RINs it generates.  What happens to the RINs the company
       cannot separate?

       A:    RINs that cannot be separated by the company per regulation section
             80.1129(b)(6) can be transferred with volumes of ethanol when the
             company transfers that ethanol to another party. This is consistent with
             the requirements applicable to parties that only import ethanol: such
             parties cannot separate any RINs they generate for imported volumes, and
             must transfer those RINs when the party transfers ethanol to the next
             owner.  (Also see Question 3.14.)
4.15   The following is a two-part question:

       a.     We are a blender. If we purchase a load of B100 (100% biodiesel) over
the quarter and sell 200 loads of B5 (5% biodiesel), what is the easiest way for us to
complete the RIN activity report as it relates to separation of RINs?

       A:    Please refer to the RFS Activity Report, Form Number RFS0100, posted at
             http://www. epa.gov/otaq/regs/fuels/rfsforms.htm.  Detailed instructions
             for completing the form are available on our website.

       b.     Our quarterly report would indicate the purchase of the load of B100.
What if we decide to blend  50% of that B100 with dyed (non-road) diesel. How do we
document the retirement of those RINs?

       A:    Retirement of those RINs is part of the information supplied on both the
             RFS Activity Report, Form Number RFS0100 and the RIN Transaction
             Report, Form Number RFS0200. Detailed instructions for completing the
             form are posted at http://www.epa.gov/otaq/regs/fuels/rfsforms. htm.

4.16   Should a biodiesel blender who blends B5 into diesel for a party that they know
       will use it for a non-road use separate or retire the associated RINs?

       A:    The RINs should be retired. Renewable fuel is defined as "motor vehicle
             fuel, " and does not include fuel intended for non-road uses. Also refer to
             the Question 4.2 and our response.
                                       24

-------
5.      Market for separated RINs

5.1     Will non-obligated parties in possession of RINs create a RIN shortage?

       A:     The in-use production volumes of renewable fuel are expected to exceed
              the requirements of the RFSprogram by a substantial margin. As a result,
              we expect there to be a surplus of RINs for at least the first few years of
              the program, and this surplus means it is highly unlikely that non-
              obligated parties could acquire and retain enough RINs to cause a
              shortage.  In addition, we expect refiners and other obligated parties to
              take ownership of renewable fuel with assigned RINs directly from
             producers in a majority of cases.  Nevertheless, EPA will monitor
             program implementation to ensure that RINs that have been generated are
              making their way to the obligated parties that need them.

5.2     If blenders either opt not to trade or are not allowed to trade, who will be
       responsible for tracking these RINs through the system?

       A:     The blender must submit quarterly RIN transaction reports to EPA that
              will document all RIN transactions, including RIN purchases, RIN sales,
              and expired RINs.  RINs that are reported purchased and thereafter are
              not sold will be identifiable through these reports. See regulation Section
              80.1152(c).

5.3     Which non-obligated parties are allowed to participate in the credit trading
       program?  Producers (with extra value RINs), oxygenate blenders, marketers?

       A:     Anyone can participate in the RIN trading program, subject to the
              requirement that the party first register with the EPA and then adhere to
              other regulatory requirements, including submitting required reports
              (such as quarterly reports on RINs held).

5.4     Can RINs at a plant expire?  Or does expiration only refer to RINs held by
       obligated parties?

       A:     Expiration of a RIN is tied to the amount of time that has elapsed since the
              RIN was generated by the producer and not to who owns the RIN. RINs
              are valid for compliance purposes for the compliance year in which they
              were generated (i.e. the YYYY code in the RIN) or the follow ing year. No
              matter who owns a RIN at the end of its valid life, it expires if it is not used
             for compliance purposes for the year generated or the follow ing year. See
              regulation Section  80.1127(a)(3). Since non-obligated parties (other than
              renewable fuel blenders) must transfer assigned RINs with renewable fuel
                                       25

-------
             (see section 80.1128(a)(3)-(5)), it is expected that most RINs that expire
             will do so in the hands of obligated parties and renew able fuel blenders.

             This question raises the associated issue of when a RIN is generated.
             RINs are generated when a batch is created by the producer and are
             assignedwhen the batch is transferred. See section 80.1126(d)-(e) of the
             regulation. Since when a batch is created is entirely under the control of
             the producer, we expect that producers will create batches in a timely
             manner that will not result in their expiration prior to their transfer to
             downstream parties.

5.5     A RIN generated in 2007 is valid for compliance purposes for both 2007 and
       2008, but obligated parties are given until February, 2009 to demonstrate
       compliance for 2008.  How do they use a 2007 RIN that expired at the end of
       2008 for compliance purposes if they don't acquire that 2007 RIN until January of
       2009?

       A:    The expiration date of a RIN refers only to the calendar year for which it
             can be used for compliance.  There is no limitation or expiration date for
             trading purposes other than the deadline for the obligated party's annual
             compliance demonstration report.  Thus a RIN generated in 2007 can
             continue to be traded in 2009, but if acquired in 2009 by an obligated
             party it could only be used for a 2008 compliance demonstration.

5.6     Who reports expired RINs?

       A:    Every party must report RINs owned that have expired as of the end of the
             fourth quarter of each year. This report is due on February 28 of the
             following year and will identify RINs that expired in the fourth quarter of
             the previous calendar year. Since RINs always expire at the end of a
             calendar year, all expired RINs will be reported.

             Since obligated parties have until February 28 to submit their annual
             compliance demonstrations to EPA (or, for 2007 compliance only, May
             31), we allow RINs to be traded between January 1 and February 28 even
             if they were generated two year previous. This means that RINs that are
             reported by a party as expired on December 31 can still be transferred to
             another party after December 31. Designating a RIN as expired is only a
             means of categorizing the RIN and does not mean that the RIN has been
             relinquished, frozen, or surrendered to the EPA.  Since this requirement
             may cause some confusion, we intend to promulgate a technical correction
             to the RFS rule to eliminate the requirement that RINs be reported as
             "expired."
5.7    Can a non-cellulosic ethanol producer have unassigned RINs?
                                       26

-------
      A:     Any party can own unassigned RINs (with a K code of 2). However, only
             producers or importers ofcellulosic ethanol can designate a BIN as
             unassigned immediately upon generating that BIN. In this case, the
             producer or importer is limited in the number of RINs they can designate
             as unassigned. See regulation Section 80.1126(e)(4).

      A tank of ethanol has become contaminated and must be disposed of. How would
      we treat this situation for RIN reporting under the RFS program?

      A:     The RFS regulation envisions various scenarios under which RINs might
             be retired. The reporting section in the regulation names a few examples:
             retirement in satisfaction of enforcement action, spill, and use in a boiler
             or heater.  We recognize that there are various other situations where RINs
             may need to be retired. Ethanol that has become contaminated and that
             requires disposal is one such situation where the RINs would be retired.
             The reporting forms contain a field for retired RINs. Reporting forms and
             instructions are now available on our website at
             http://www. epa. sov/otaci/ress/1uels/rfsforms. htm.
5.9    Can anyone own RINs and participate in the RIN market?

       A:     There is no restriction on who may own RINs. Anyone can own RINs,
             including private citizens. However, parties who own or intend to own
             RINs must register with us under 80.1150(c) and recordkeeping, reporting
             and attest engagement requirements related to RIN transactions apply.
             See 80.1151 (d), 80.1152(c) and 80.1164(c).

5.10   Biodiesel may be blended into non-road diesel or denatured ethanol may be
       blended into gasoline designated for non-road use. How are the RINs retired and
       reported to EPA by the blender?

       A:     The blender would report the RIN purchase transaction and then would
             report the RINs as retired when he blends the renewable fuel associated
             with the RINs into the non-road fuel. The appropriate forms to use are the
             RFS Activity Report, Form Number RFS0100, and the RFS RIN
             Transaction Report, Form Number RFS0200.  These forms and
             instructions are located on our website at
             http://www.epa.gov/otaq/regs/fuels/rfsforms.htm .  Also refer to the
             regulation at sections 80.1152(c)(l)(x) and (c)(2)(xii)for guidance on
             retirement of RINs. In the case of the same RINs transferred, mistakenly
             or otherwise, to two or more parties, all such RINs, by all parties holding
             them, should be reported as retired unless EPA determines that some
             portion of them are valid..
                                       27

6.      Obligated and nonobligated parties

6.1     Are gasoline blenders no longer considered obligated parties? I have seen
       references to gasoline refiners and importers only. Gasoline refiners may also
       serve as blenders.

       A:     Any party that produces gasoline (broadly defined at 80.110 7(c)) from
             non-renewable feedstocks or blendstocks is an obligated party under the
             RFSprogram. This would include gasoline blenders unless their sole
             activity is adding renew able fuels to gasoline. See sections 80.1106(a)(l)
             of the regulation. For more information about small refiners, see the
             answer to Question 6.6 below.

6.2     I am a small volume renewable fuel producer, and so should be exempt from the
       requirement to generate RINs and assign them to  renewable fuel that I produce.
       Do I need to submit a form to EPA proving that I produce less than 10,000
       gallons a year?

       A:     No. Small volume producers are automatically exempt. How ever, if a
             small volume producer chooses to register as a renewable fuel producer
             under the RFS program, they will be subject to all the regulatory
             provisions that apply to all renewable fuel producers, including the
             requirement to assign RINs to batches. See regulation Section 80.1126(b).

6.3     Who is a renewable fuel producer?  Will the EPA recognize ethanol marketing
       companies as producers? Can the term "producer" apply to a marketing company
       who represents various producing plants?

       A:     Renewable fuel producers are parties that produce renewable fuel (i. e.
             convert a renewable feedstock into a renewable fuel). RINs must be
             generated by the producer and assigned to renewable fuel by the time title
             to the renewable fuel is transferred from the producer to another party
             such as a marketer. See regulation Sections 80.1126(d)(l) and (e)(2). In
             turn, the marketer must transfer assigned RINs to the party to whom  the
             marketing company sells the ethanol.

             Marketing companies who "represent" renewable fuel producers are not
             producers unless the marketing company produces renewable fuel, and
             such a company would only generate RINs for that part of the renewable
             fuel that they actually produced. Ethanol marketing companies that do
             not produce or import renewable fuels are not renewable fuel producers
             or importers and cannot generate RINs.

6.4     Is an ethanol plant  that splash blends into gasoline an obligated party?
                                       28

-------
      A:    If a facility only blends ethanol into gasoline, they are not an obligated
             party and thus do not have a Renewable Volume Obligation (RVO).
             However, they are still regulated parties and are thus subject to the
             registration, recordkeeping, and reporting requirements.

6.5 The following is a two-part question about the responsibilities of exporters.

      a.     We are a foreign company that markets ethanol. We do not produce
             ethanol, nor do we import it into the U.S. What is our obligation when we
             move product (export) out of the U.S.?

             A:     Section 80.1130 describes the responsibilities of exporters. Note
                    that if any party owns renewable fuel that is exported from the
                    region described in 80.1126(a) [currently the 48 contiguous
                    United States, although Hawaii has requested to opt in], sufficient
                    RINs must be acquired to offset an RVO representing the exported
                   fuel. There are also registration, recordkeeping, reporting, and
                    attest engagement requirements applicable to exporters, and set
                   forth at 40 CFR 80.1150(a), 80.1151(a), 80.1152(a) and
                    80.1164(a).

      b.     How do we figure out batch and facility numbers for reporting purposes?

             A:     Batch numbers are 5-digit numbers that are part of the RIN and
                    are described in 80.1125(e). Unless you are an  importer or
                   producer of renewable fuel, you do not need a facility number.
                    Renewable fuel exporters do, however, require a company
                    identification number.   See 40 CFR 80.1150 (a)&(c).

6.6   We are best described as a "terminal blender" or "terminal refiner." We do not
      operate a distillation tower and we do not process crude oil.  We produce gasoline
      from blending components that have been previously certified by another refiner
      and that are not considered "gasoline" under EPA's definition.  We produce less
      than 75,000 barrels per day  and are not owned or affiliated with anyone else. Are
      we a "small refinery" under the RFS regulation and not an obligated party until
      2011, unless we opt into the program?

      A:    No.  You are an obligated party now. EPA's definition of "small refinery"
             is identical to the definition used in EPAct, as it was intended to
             implement the EPAct provisions. EPAct clearly treats refineries
             separately from blenders.  (See EPAct sections 211(o)(3)(B)(ii)(I) and
             (o) (2) (A) (Hi) (I) for examples of this separate treatment.) EPA  reads the
             EPAct definition of "small refinery" to specifically exclude  entities such as
             yours that produce gasoline solely through blending.
                                       29

-------
6.7    We are best described as an "intermediate feedstock processor".  We produce
       gasoline by processing feedstocks (that are derived from crude oil) in processing
       units which are the same as those used in crude oil refineries. We process less
       than 75,000 barrels of feedstocks per day, and are not owned or affiliated with
       anyone else.  Are we a "small refinery" under the RFS regulation and not an
       obligated party until 201 1, unless we opt into the program?

       A:    Yes. EPA 's definition of "small refinery" is identical to the definition used
             in EPAct,  as it was intended to implement the EPAct provisions.  EPAct
             defines a small refinery as a refinery for which the average aggregate
             daily crude oil throughput for a calendar year does not exceed 75,000
             barrels. (See EPAct section 1501(o)(l)(D)). EPA reads the EPAct
             definition of "small refinery" to include refineries that process feedstocks
             derived from crude oil, using processing units which are the same as those
             used in refineries that process crude oil all the way to finished product.
             The crude oil-derived streams are essentially components of crude that
             have been physically separated through distillation, or other processes,
             and require further processing. Refineries that perform this additional
             processing are continuing the  crude oil refining process, and EPA
             therefore considers them to be crude oil refineries for purposes of EPAct.
             If the average aggregate throughput of feedstocks at such a refinery is less
             than 75, 000 barrels/day, EPA  considers the refinery to be a small refinery.


6.8    I am an ethanol marketer and importer, and, although I am not certain, I may
       import gasoline before the end of the compliance year. Can I separate RINs from
       the ethanol that I purchase and import?
      A:    In general, we believe that most RFS program participants will know at
             the beginning of the compliance year the nature of their business activities
             for the upcoming compliance period, and therefore will not need to worry
             about the impact of changing roles and responsibilities mid-way through
             the compliance period.  However, we understand that there may
             occasionally be parties that did not anticipate becoming obligated parties
             at some point during the compliance period but, in fact, do so.  Obligated
             parties must separate all RINs that they receive with purchased renewable
             fuel, and they may separate, up to their Renewable Volume Obligation
             (RVO), RINs that they generate for renewable fuel which they have
             imported or produced.  Other parties regulated under the RFS, such as
             renewable fuel producers, importers, and marketers, do not have the same
             obligations.  Therefore, if a non-obligated party should become an
             obligated party mid-way through a compliance period without having
             anticipated that such a change of status would occur,  the question arises
             as to how that party should handle RINs both before and after their
             change of status.
                                       30

-------
EPA believes that a party who is unsure whether or not they will become
an obligated party (e.g., by importing gasoline during the compliance
period) should not act as an obligated party (e.g., by separating RINs
from renewable fuel) unless and until they know for certain that they will
become an obligated party. In this way, if the party does not become an
obligated party during the compliance year, they will not be in violation of
the RFS regulations that prohibit non-blenders and non-obligated par ties
from separating RINs from renewable fuel (Sec. 80.1128(a)(2)).   On the
other hand, if a party is uncertain that they will become an obligated party
during the  compliance period, they will not be subject to the requirements
associated with being an obligated party (e.g. the requirement to separate
RINs) until they are certain of that status during the compliance period.

However, once a party is certain that they will engage in activities that
will make them an obligated party within the compliance period, they
should assume the obligations and requirements associated with obligated
party status for the remainder of the compliance period. If a party acts as
an obligated party throughout the compliance period (e.g., separating
RINs with purchased renewable fuel), that party will be in violation of the
RFS regulations unless, at some time during the  reporting period, they
meet the definition of an obligated party.

-------
7.      Renewable Volume Obligations (RVO)

7.1     If a specific refinery is the producer of renewable diesel, I assume they need a
       facility ID number, but we can use the RINs for aggregate company compliance.

       A:    Yes.  The facility ID number is used to generate the RIN, but the RIN can
             be separated and used for compliance on a company-wide aggregate
             basis, subject to any applicable restrictions in the regulations such as
             regulation Sections 80.1106(c) and 80.1129 (b) (6).

7.2     If an ethanol producer imports a truckload of gasoline, they are an obligated party
       and have an RVO. Does this mean that they can separate RINs from all the
       ethanol they produce?

       A:    Not necessarily. Obligated parties can only separate RINs they generated
             for renewable fuel they produced or imported up to the level of their RVO.
             They are not allowed to separate additional RINs that they generated.
             However, obligated parties must separate all RINs from renewable fuel
             that they own if they did not generate those RINs.  See regulation Sections
             80.1129(b)(l) and (b)(6).

7.3     Who actually calculates the RVO? The refinery or EPA?

       A:    Each obligated party calculates the RVO itself, based on its annual
             gasoline volume. See regulation Sections 80.1152(a)(l)(v) and (vi).

7.4     CARBOB doesn't appear in the list of fuels comprising the RVO
       (regulation Section 80.1107). However, in the Preamble, EPA mentions RBOB
       and CBOB.  Is CARBOB considered a subset of RBOB?

       A:    The regulations include in the list of products to be included in the volume
             used to calculate the RVO "Any gasoline, or any unfinished gasoline that
             becomes finished gasoline upon the addition of oxygenate, that is
             produced or imported to comply with a state or local fuels program. "
             CARBOB would fall under this category.  See regulation Section
             80.1107(c)(6).

7.5     To whom does the 20% limit on previous year RINs apply?

       A:    This limit applies only to obligated parties.  Under regulation Section
             80.1127(a)(2), no more than 20% of the gallon-RINs  used by an obligated
             party to meet its RVO can be previous-year RINs (having a YYYY code
             that is one year earlier than the year for which the RIN is being used to
             show compliance with an RVO).
                                       32

-------
7.6    What happens if, after submitting his annual compliance demonstration report, a
       refiner discovers that he exceeded the 20% cap on the use of previous-year RINs
       in meeting his RVO? Is he required to replace those RINs with new valid RINs at
       the old market price?

       A:     Annual compliance demonstrations must include a showing that the RINs
             used to comply with the RVO include no more than 20%previous-year
             RINs. If it is determined that this showing was incorrect due to either a
             mathematical error or the discovery that some of the current-year RINs
             were invalid, or for any other reason, the obligated party must revise the
             compliance demonstration by adding additional current-year RINs to  the
             compliance demonstration until the 20% maximum is met.  If sufficient
             current-year RINs are not already owned by the obligated party, he will
             need to acquire them  through transfers from other parties. If the
             obligated party cannot acquire sufficient additional current-year RINs to
             meet the 20% criterion, he may be able to reduce the number of previous-
             year RINs used below the 20% level and then carry a deficit into the next
             year.

             If a party discovers an error and must submit a corrected report, it may
             download the appropriate form and instructions from our website at
             http://www. epa. gov/otaq/regs/fuels/rfsforms. htm.  There is afield that the
             reporting party marks for resubmissions.
7.7    It appears we are creating an automatic non-compliance period for September,
       2007.  If I own ethanol on September 1, 2007, it will not have assigned RINs. As
       an obligated party, I will be blending this ethanol into gasoline at my terminal, but
       I won't be getting any RINs for that ethanol.

       A:    It may be the case that some ethanol blended into gasoline at the
             beginning of the program will not have assigned RINs.  However, the RVO
             is determined annually, not quarterly or monthly, and in general ethanol
             purchased after September 1, 2007 will have assigned RINs.  Obligated
             parties can also acquire RINs in the first few months of 2008 that can be
             used to demonstrate compliance with their 2007 RVO.
                                       33

8.      Company and Facility Registration

8.1     When will the EPA registration forms be ready to obtain the plant and facility ID
       numbers?

       A:    Registration forms may be submitted any time after May 1, 2007, the
             publication date of the final RFS rules.  See regulation Section
             80.1150(a).  Registration forms and instructions are linked to our RFS
             page at http://www.epa.gov/otaq/renewablefuels/. Potential registrants
             can fill the form out on the web site, submit it electronically to EPA and
             print out a copy which then must be signed by the responsible corporate
             officer and sent to EPA (directions for sending are on the forms).  When
             EPA receives the signed copy of the registration, EPA will email the
             registrant with confirmation of registration and an appropriate ID
             number.

8.2     If my company and facilities are already registered with EPA under another
       program, do I have to register for RFS?

       A:    No, but you are responsible for updating your company or facility
             information within 30 days of a change. See regulation Section
             80.76(e)(l).  Registration forms and instructions are linked to our RFS
             page at http://www.epa.gov/otaq/renewablefuels/.

8.3     If my company or facility information changes, how do I correct that in the EPA
       registration system?

       A:    You are responsible for notifying EPA of any changes to your information.
             You may do so by filing the online registration form indicating that you
             are updating an existing registration,  and mailing a printed copy of the
             form to the EPA.

8.4     How will I know that my registration has been processed by EPA?

       A:    EPA will provide you with company and facility ID numbers after we have
             received a mailed copy of your registration form(s).  Since you need these
             numbers prior to engaging in transactions involving RINs, it is advisable
             to register as early as possible.

8.5     Will third party marketers have different registration forms to  complete than
       producers?

       A:    No.  The registration form for third party marketers is  the same form as
             the producer registration form.  However, third party marketers are only
                                       34

-------
              required to obtain an EPA company identification number and not a
             facility identification number.

 .6    Could a marketing company register as a producer with the EPA to represent
       multiple plants?

       A:     No.  Each renewable fuel producer must register and is responsible for
              generating BINs (with an exception for some producers/importers that
             produce or import less than 10,000 gallons of renewable fuel each year).
8.7    What business activity should producers and marketers register under?

       A:    Producers and marketers should register as RIN owners and, as
             appropriate as an ethanol producer/importer, biodiesel
             producer/importer,  and under any other category that applies to them.
             Registration is available on-line at
             http://www. epa. gov/otaq/regs/fuels/fuelsregistration. htm.  If a party is
             unsure how to register after reviewing the forms and instructions, we have
             staff who can assist them and their contact information is given on the
             webpage.

8.8    Are plants blending E-85 considered oxygenate blenders?

       A:    Such parties should register as RIN owners. See our response to Question
             8.7 regarding availability of registration forms, instructions, and
             assistance.

8.9    Must an importer of renewable fuels  register with EPA for each facility that it
       imports to?

       A:    Yes. Such a party should register each import facility or the facility where
             the denaturant is added. See  section 80.1150(b) of the regulation.

8.10   What qualifies as a facility for an importer - e.g., the receiving port, the storage
       tank, or both?

       A:    In order to be registered, the facility must have a name and a physical
             street address. For example,  one cannot register its facility as "Port of
             Baltimore, " but may register  a terminal facility located at an address
             within the Port of Baltimore.  Registration forms, instructions, and staff
             contacts for assistance are available on our website at
             http://www.epa.gov/otaq/regs/fuels/fuelsregistration.htm.

8.11   If ethanol is imported from Brazil and the denaturant is added in Brazil, does the
       Brazil facility need to register?
                                        35

-------
      A:     No, but the importer of the ethanol must register.

8.12  Do terminals need to register?

      A:     Terminals do not need to register.  However, terminals that engage in
             activities that require registration must be registered. For example, if the
             terminal takes ownership ofRINs, then it must be registered as a RIN
             owner.
8.13   My plant makes ethanol, but only through recycling contaminated batches of
       existing ethanol ("waste" ethanol), not through fermentation. Do we need to
       register under the RFS program? Are we subject to reporting requirements?

       A:      The RINsfor the contaminated ethanol should have been retired.
             Assuming they have been, then you would be a renewable fuels producer,
             subject to registration as a producer and responsible for generating and
             assigning RINs.  You would also be subject to recordkeeping, reporting,
             and attest engagement requirements Any production claimed as "waste
             derived" would have to undergo certification,  including an engineering
             review, under section 80.1155 of the regulation.
                                       36

-------
9.      Recordkeeping and Product Transfer Documents (PTDs)

9.1     How is a Product Transfer Document defined? Must it be an invoice, bill of
       lading (BOL), or can it be either?

       A:     The regulations do not specify the form of a product transfer document
              (PTD), but do include a list of information that must appear on the PTD.
              See regulation Section 80.1153(a). In the context of the RFSprogram,
              PTDs must identify a transfer of ownership of a volume of renewable fuel.
              In general this would mean invoices. PTDs would in most cases not
              include a bill of lading, which is used primarily for a transfer of custody
              rather than a transfer of ownership.

9.2     As RINs are transferred, do they have to be attached to a PTD  (i.e. printed on a
       BOL), or can they be transferred in an electronic spreadsheet that references a
       PTD?

       A:     The PJN must appear in its entirety on PTDs identifying a transfer of
              ownership of a volume of renewable fuel. (In general PTDs would not
              include BOLs, which are used for transfers of custody rather than
              transfers of ownership.) However, the PTD transferring the RINs can be a
              separate and parallel PTD from that used to  transfer the renewable fuel to
              which those RINs are assigned. PTDs can be electronic, including
              computer spreadsheets. See regulation Section 80.1153(a)(5).

9.3     If I am an oxygenate blender who purchases directly from a renewable fuels
       producer, RINs are transferred with ownership of the batch. Therefore, I will be
       in possession of the RINs. How will these RINs be accounted  for in my records?

       A:     You must keep a database of all RINs that you take ownership of at any
              time during a compliance period, and report those RINs to EPA quarterly.
              See regulation Sections 80.1151(d) and 80.1152(c).

9.4     The regulations at Section 80.1151(b)(5) say that producers must keep "records
       related to the production or importation of renewable fuel that  the renewable fuel
       producer or importer designates as motor vehicle fuel and the use of the fuel as
       motor vehicle fuel."  What does this mean?

       A:     This requirement is limited to cases in which a producer or importer
              wants to separate assigned RINs from a volume of renewable fuel under
              the provisions at regulation Section 80.1129(b)(4).  If the renewable fuel
              that the producer  or importer produces or imports can  be used in its neat
              (unblended) form, it can be designed a motor vehicle fuel without being
              blended with conventional gasoline or diesel. In order to claim the right
              to separate the RINs that have been generated and assigned to such fuel,
                                       37

-------
             the producer or importer must retain records demonstrating that the
             renewable fuel has been used as motor vehicle fuel in its neat form.

9.5    Can RIN tracking and transfer be handled completely electronically? If so, can
       we choose the software and the report format?

       A:    You may keep the records in any format you wish.  How ever, you must be
             able to provide readable copies to EPA representatives upon request and
             you must retain records and the means to read them for at least five (5)
             years. You must either be able to convert the records to a readable format
             or provide them in a usable electronic or paper format as requested by
             EPA. (For the purpose of reporting, you may use any commercially
             available format or comma delimited-text. Please refer to Section 10 of
             this Q&A document - Reporting and the EPA 's Central Data Exchange.)
             Note that on product transfer documents (PTDs) (which are required
             when ownership of a renewable fuel is transferred to another party),
             certain information may be conveyed to some parties through the use of
             product codes; however, information regarding assignedRINs transferred
             with the renewable fuel must always be included on the PTDs.  See
             regulation Section 80.1153(a)(5) and (b).

9.6    If there's a partial gallon on the BOL, how do companies handle rounding when
       tracking RINs?

       A:    The number of assigned gallon-RINs being transferred by parties other
             than renewable fuel producers or importers need not correspond exactly
             to the number of gallons being transferred. See regulation Section
             80.1128(a)(4). Thus  in general the presence of a partial gallon on aPTD
             will not affect the tracking of RINs.  For producers and importers of
             renewable fuel who are required by regulation Section 80.1128(a)(6) to
             transfer a specified number of gallon-RINs with each gallon of renewable
             fuel, partial gallons can be rounded to the nearest whole gallon so long as
             the number of renewable fuel gallons is consistent with the number of
             gallon-RINs.

9.7    A marketer communicates RINs transferred to a buyer via the invoice.  Is it
possible for the  invoice to follow the transfer of title to  the buyer by a few days?  Must
the same PTD be used to transfer the RINs and  the renewable fuel volume?

       A:    The PTD may take  the form of an invoice, bill of lading, or other
             document meeting the requirements of section 80.1153 of the regulation.
             The PTD identifying the RINs must be transferred to the buyer on the
             same day as the transfer of title of the fuel. Separate PTDs may be used,
             but the PTD transferring the fuel must reference the PTD transferring the
             RINs.
                                       38

-------
9.8    Are PTDs given to third party terminals and pipelines by obligated parties and
       that reflect custody transfers only, required to identify RINs?

       A:    No, such PTDs are not required to identify RINs. PTDs consistent with
             80.1153 are required only for transfers of ownership of renewable fuel.

9.9    The RFS regulation requires that, where RINs are transferred via a separate
       document from the PTD used to transfer ownership of the renewable fuel, the
       PTD transferring the fuel must state the number of gallon-RINs being transferred
       and must also have a unique reference to the PTD which is transferring the
       assigned RINs. What does EPA require for a "unique reference?"  See section
      A:    There is no EPA-pr escribed method for a unique reference.  The intent of
             the unique reference is to tie the two PTDs together - i.e., to join the
             records for the volume transaction and the PJN transaction in some
             manner.  Some companies who engage in few of these transactions might
             be able to use simple document names as their unique reference. Those
             parties with many of these transactions might incorporate date and time
             or other useful information into their unique reference. Each company is
             in the best position to determine what they need to do.

9.10  We engage in blending and refining and expect to be purchasing RINs separately
      from purchases of renewable fuel. The PTD requirements of section
      80. 1 151(d)(l) indicate that a PTD is only required when title to a renewable fuel
      is transferred. If so, then what document would be sent to us with RINs
      purchased separately from purchases of renewable fuels?

      A:    There is no PTD requirement for transfers of separated RINs, but records
             related to RIN transactions must be kept.  The PJN transaction would have
             to be reported and underlying records must be retained.  See
             80.1151(d)(3) and80.1152(c).

9.11  The recordkeeping requirements in  section 80.1151 state that we must keep
      records of the parties involved in each transaction, including the transferor,
      transferee, and any broker or agent. What identifiers are required for transferor
      and transferee? Do we need both the EPA issued company and facility ID
      numbers?

      A:    For recordkeeping purposes, you want to retain records that help explain
             what appears on your  PTDs and in your reports to EPA.  This would
             include the name of the party and any applicable EPA issued ID numbers,
             but you may wish to keep additional identifying information in your
             records as well.
                                       39

9.12   We sell ethanol by the truck load (870 gallons at a time). Each pick-up is
       considered a transaction, so if a company picks up 20 loads in a day they send us
       20 electronic invoices.  Under 80.1128(a)(7)(ii) can we create a new PTD and
       send the company a bill at the end of the day showing 20 pick ups but one total
       each for gallons and RINs?

       A:    You could create one PTD, but it would have to be transferred to the
             receiving party on  the same day as the transfer of ownership.  The single
             PTD would list all the RINs transferred for the day and the 20 invoices
             would also have to reference the single PTD document.

9.13   Is a PTD required for transferring an unassigned RIN?

       A:    No. PTDs are not required when transferring unassigned RINs.
             However,  PTDs are required whenever there is a transfer of ownership of
             a renewable fuel. Where the fuel is being transferred with assigned RINs,
             then the PTD must include information relating to the RINs. See section
             80.1153 of the regulation.  If the renewable fuel is being transferred
             without the RINs, then the PTD must state "no RINs transferred. "

9.14   In many cases, no document is created on the date that title of the renewable fuel
       is transferred to the purchaser, which typically is the date the purchaser receives
       the fuel, and an invoice typically is used by the parties to recognize the transfer of
       title to the fuel. The invoice may be created either at the time of shipment or after
       the product is received.  Can such an invoice be used to fulfill the product transfer
       documentation requirements under the RFS rule?

       A:    The regulations at section 80.1128(a)(7) provide that any RINs assigned
             to a renewable fuel must be recorded on the product transfer document
             used to transfer ownership of the renewable fuel volume to another party,
             or the RINs may be recorded on a separate product transfer document
             transferred to the same party on the same day as the product transfer
             document used to transfer ownership of the volume of renewable fuel.  We
             believe,  where the parties use an invoice as the document which transfers
             title to a batch of renewable fuel, the product transfer documentation
             requirements in section 80.1128(a)(7) are satisfied where the RINs
             assigned to the fuel are included either on that invoice or on a separate
             document which is transferred to the purchaser on the same day that the
             invoice is  transferred. Where a separate document is used, the invoice
             must include the number of gallon-RINs assigned to the fuel and reference
             the document which transfers the RINs.
9.15   We are considering developing a PTD that lists ethanol and denaturant as separate
       items being transferred. RINs would be generated for the entire volume of
       denatured ethanol. If, for example, we transfer 950 gallons of ethanol and 50
                                       40

-------
       gallons of denaturant, may we split the gallon- RINs between ethanol and
       denaturant? Or would we only indicate the number of gallon-RINs associated
       with the entire volume of denatured ethanol (i.e., 1000 gallons)?

       A:      The RINS should not be split between ethanol and denaturant. Section
              80.1153(a) of the RFS rule refers to "the volume of renewable fuel that is
              being transferred" as necessary information for PTDs. Denatured ethanol
              is the "renewable fuel" in your example.  It would be incorrect to split the
             RINs between ethanol and denaturant.
10.     Reporting and the EPA's Central Data Exchange (CDX)

10.1    Is the RIN transaction report tracked daily but reported quarterly?

       A:    With regard to reporting to EPA, each RIN transaction (i.e., RIN sale or
             purchase, retired or expired RIN) must be reported on a separate RIN
             transaction report.  The RIN transaction report for each transaction must
             be submitted to EPA by the end of the second month after the quarter in
             which the transaction occurred.  See regulation Section 80.1152(c)and
             (d). The reports for RIN transactions that occurred within a quarter may
             be submitted all together, individually, or in groups at any time, so long as
             the transaction reports for all transactions that occurred during the
             quarter are submitted to EPA by the end of the second month after the
             quarter in which the transactions occurred. With regard to transfer of
             RINs between parties, such transfers must be included on some type of
             product transfer documentation as explained in the section of this
             document dealing with Recordkeeping and Product Transfer Documents
             (PTDs).

10.2    For parties that take ownership of assigned RINs and then separate them, do they
       report those RINs with K code of 1  or 2?

       A:    The regulations state that, in most cases, (1) a party that is an obligated
             party must separate any RINs that have been assigned to a volume of
             renewable fuel if they own that volume, (2) any party that owns a volume
             of renewable fuel must separate any RINs that have been assigned to that
             volume once the volume is blended with gasoline or diesel to produce a
             motor vehicle fuel, and (3) the party responsible for separating a RIN
             from a volume of renewable fuel shall change the K code in the RIN from
             a value of 1 to a value of 2 prior to transferring the RIN to any other
             party.

             In the case of an obligated party, Company A, that has accepted a volume
             of renewable fuel with an assigned RIN, Company A must change the K
                                       41

-------
             code from 1 to 2.  However, in a transaction report filed by Company A
             concerning receipt of the RIN, the RIN would be reported with a K code of
             1 (i.e., as it was received).  If the RIN is transferred to another party by
             Company A during the reporting period, Company A would report the RIN
             on a transaction report for that transfer with a K code of 2. If the RIN was
             used for compliance, Company A would report the RIN with a K code of 2
             on its annual compliance report.

             In the case of a blender, the RIN would be reported with a K code of 1 for
             the  transaction relating to the receipt of the renewable fuel. After the
             blender blends the renewable fuel into motor vehicle fuel, the RIN would
             be reported with a K code of 2 for a transaction relating to the transfer of
             the  RIN to another party.

             In EPA 's reporting instructions, it will be made clear how a party should
             report the K code for any given report.

10.3   What is the process to retire a RIN? Is this a reporting function that is done with
      the EPA?

      A:     RINs are retired for reasons specified in the regulations and must be
             reported to EPA.  A  retired RIN may not be used for compliance purposes
             or traded to another party.  A retired RIN is reported to EPA  in a RIN
             transaction report and the total number of RINs retired during a quarter is
             reported to EPA in the gallon-RIN activity report. A RIN transaction
             report that reports a retired RIN must describe the reason for retiring the
             RIN. Potential reasons include reportable spills under regulation Section
             80.1132, import volume corrections under regulation Section
             80.1166(e)(2),  renewable fuel used in boiler or heater under regulation
             Section 80.1129(e), RINs that are invalid (other than expired RINs) or
             RINs required to be  retired in the context of an enforcement action.  For
             reporting requirements, see regulation Section 80.1152.

10.4   I haven't seen a reference to the EPA CDX system. Is the CDX system already
      established or can we  submit reports in our choice of electronic formats?

      A:     The Central Data Exchange (CDX) is an established portal through which
             electronic data are submitted. All registered parties will have to first
             register with CDX in order to receive a CDX registration number. A link
             to the CDX web site will be provided from our RFSweb site at
             http://www. epa.gov/otaq/renewablefuels.  RFS reports can be produced by
             vendor software or by using spreadsheet templates or other data templates
             following instructions linked to the RFSweb site.

10.5   Do I have to register to use  CDX and is this  a separate registration process?
                                       42

-------
      A:     You will have to register with CDX. (Registering with CDXis not the
             same as registering under regulation Section 80.1150.) Instructions are
             available via our RFS web page at
             http://www.epa.gov/otaq/renewablefuels/.
10.6  When will the template report forms for all of the RFS-required reports be
      available; will these be posted on the website?

      A:     They are available now at http://epa.gov/otaq/regs/fuels/rfsforms.htm.

10.7  If you have  a spill, does the K code change to 2 for the spilled volume?

      A:     No, the K code is not changed as the result of a spill.  (Refer to section
             80.1132 of the regulation regarding retirement ofRINs due to a spill.)

10.8  What recordkeeping and reporting requirements do exempt small refineries and
      small refiners have?

      A:     Exempt small refineries and small refiners have no recordkeeping and
             reporting requirements until 2011, unless they choose to own RINs.

10.9  Is there any  benefit to aggregating refineries for reporting purposes?

      A:     Aggregation does not provide any "advantage " under our regulation.
             Whether or not to aggregate refineries for reporting purposes is a
             practical decision that we have left up to the individual companies.  For
             example, some companies have one integrated recordkeeping and
             reporting system for all their refineries,  whereas others do not.

10.10 If a transaction must be reversed for some reason, does the reversal have to track
      specific RINs or will fungible RINs work? How is this reported?

      A:     The original transaction (involving the specific RINs) should be nullified
             and,  if already reported to EPA, corrected reports should be submitted.  If
             discovered prior to being reported to EPA, then all associated records
             must be corrected. If a transaction must be reversed for any reason, then
             PTDs must be corrected and must track the specific RINs.

10.11 What happens if a party registers with EPA then engages in no activities that must
      be reported  during a given compliance period?

      A:     There is no obligation to report if no activity occurs.
                                       43

-------
10.12 If an obligated party (a refiner) imports non-denatured ethanol and denatures it, is
      the refiner considered a renewable fuel producer and is the refiner obligated to
      establish RIN numbers and file quarterly reports for the ethanol it denatures?

      A:    The party would be identified as a renewable fuel importer rather than a
             renewable fuel producer, and would need to establish RIN numbers and
             file reports required of an importer.   The party in this example would
             also be required to file reports required of a refiner.

10.13  Is it correct that an obligated party must still file the quarterly RIN activity report
      even though all RINs held are separated (or unassigned, with a K code of 2)?

      A:    Yes.  Although obligated parties are not subject to the end-of-quarter
             check described in regulation Section 80.1128(a)(5) (because all RINs
             become unassigned immediately upon ownership by an obligated party),
             they must still report all of their RIN activities quarterly, including RIN
             purchases and sales.  See regulation Section 80.1152(c).

10.14 Does a plant have to have their EPA-issued company ID number before they
      register for CDX?

      A:    Yes,  this ID will be necessary to complete the CDX registration process.
             You may look up your company ID number  at
             http://epa.gov/otaq/regs/fuels/rfs-list.xls (in Excel spreadsheet format).

10.15 Where a company  is both an obligated party and an importer of renewable fuel,
      the company will generate RINs in its importer capacity and separate the RINs
      from the volume of imported fuel in its capacity  as an obligated party. Is this
      activity considered a "transfer" for purposes of submitting a RIN transaction
      report under the RFS program?

      A:    No transaction report is required for internal company transfers as all
             RINs are owned at the corporate level. The company would submit a RIN
             generation  report for the RINs it generated for the imported renew able
             fuel and a compliance demonstration report to demonstrate compliance
             with its RVO.  The company would also submit a quarterly gallon-RIN
             activity report.
                                       44

11.     Other Questions

11.1    What entity retires the RIN if the same RIN is mistakenly transferred to two or
       more parties?  Does the plant retire the RIN? Does the EPA have to be notified?

       A:     Where a RIN is invalid because the same BIN was transferred to two or
             more parties, all such RINs are deemed invalid unless EPA determines
             that some portion of them is valid.  See regulation Section 80.1131(b)(4).
             In the absence of such determination by EPA, all parties with such RINs
             must under regulation Section 80.1131(b)(2), adjust their records, reports
             and compliance calculations as necessary to reflect the deletion of the
             invalid RINs.  "Deletion " refers to annual compliance reports since an
             invalid RIN cannot be used to show compliance. In the case of RINs
             transferred to two or more parties, all such RINs, by all parties holding
             them, should be reported as retired unless EPA determines that some
             portion of them are valid.

11.2    Regulation Section 80.1131 (b)(4) states that, in the event that the  same RIN is
       transferred to two or more parties, "all such RINs will be deemed  to be invalid,
       unless EPA in its sole discretion determines that some portion of these RINS is
       valid". What's the process to determine if a portion of RINs are valid?

       A:     In many circumstances, EPA will be able to determine whether any of the
             RINs (or particular gallon-RINs within a batch-RIN) are valid from the
             information submitted to EPA in the RIN generation and transaction
             reports.  Through these reports, it is possible to track a RIN from the point
             of generation by the renewable fuel producer or importer through each
             transaction until the RIN is used for compliance, retired or has expired. If
             EPA determines that a RIN is invalid, EPA would contact the submitter of
             the report(s) with the invalid RIN and advise the party how to proceed.

11.3    If a party buys a batch of ethanol, and through testing determines that the  ethanol
       is synthetic (non-renewable), what happens to the RINs?

       A:     If a volume of renewable fuel for which RINs have been generated is found
             to not be a valid renew able fuel under the RFS program, then the
             associated RINs are likewise deemed invalid. See regulation Section
             80.1131. If a party determines that a batch of fuel that they own does not
             meet the definition of renewable fuel under the RFS program, the RINs
             received with such fuel must be deleted from records, reports and
             compliance demonstrations. See regulation Section 80.1131. In general,
             RINs received with such fuel must be reported as retired and such invalid
             RINs must be deleted from any compliance reports.  Parties that learn of
             such a situation should promptly inform EPA. EPA will investigate the
             source of the fuel and take appropriate action.
                                       45

-------
11.4  What metering system does the plant use to measure gallons? Is it a production
      meter, a load-out meter, etc.?

      A:     EPA regulations provide flexibility in terms of the specific mechanisms
             through which producers and importers measure volumes for purposes of
             generating RINs. However, the approach should ensure that gallons are
             neither systematically ignored nor systematically double-counted.  Also,
             approaches that provide consistent volumes for both the RFS program and
             other contexts such as reporting to the Energy Information Administration
             are preferred.
11.5   Are only owners of small refineries as of January 1, 2004 allowed to claim the
      small refinery exemption? If so, how is this date justified?

      A:     Only owners of small refineries as of January 1, 2004 are eligible, As
             explained in the preamble (see 72 FR 29525)EPA believes that small
             refinery eligibility should be based on 2004 data rather than on 2005
             data, since it was the first full year prior to passage ofEPAct. In addition,
             some refineries' production may have been affected by Hurricanes Katrina
             and Rita in 2005.

11.6   How is the small refinery verification letter structured?

      A:     The structure  of the letter is left up to the individual.  The letter must
             address the items in section 80.1141(b)(2) of the regulation.

11.7   What is the estimated value of a RIN?

      A:     There is no way to estimate the  "market value " of a RIN, as this will be a
             changing value and entirely determined by the marketplace.

11.8   What mechanisms exist to suspend RFS program requirements,  should renewable
      supply be limited due to natural disasters?

      A:     EPAct contains a provision to address unforeseen circumstances that may
             occur which result in a shortage of renewable fuel and available RINs and
             we believe that the statutory provision is sufficient to address unforeseen
             circumstances that may occur on a nationwide or regional scale.
             Specifically,  EPAct provides that on petition by one or more States,  EPA,
             in consultation with the Departments of Agriculture and Energy, may
             waive the required aggregate renewable fuels volume obligation in whole
             or in part upon a sufficient showing of economic or environmental harm,
             or inadequate supply.  As explained in the preamble to the rule (see  72 FR

             23927) the RFS rule is a flexible program that permits trading ofRINs
             and deficit carryovers.
11.9  Which market indicators will cause EPA to change the RFS standard?

      A:     EPA will use information from the Energy Information Agency (ElA) that
             projects volumes of gasoline and renewable fuel in order to calculate the
             standard.  Please refer to section 80.1105 of the regulation.
11.10  Since ethanol use is expected to surpass the mandated EPAct levels, is there any
       mechanism available to EPA to allow compliance on a national collective basis,
       as was done under the 2006 default rule?

       A:     No.  The Energy Policy Act included a specific default provision for 2006
             that was to go into effect if the RFS program regulations were not in
             place.  That provision was expressed in general terms, allow ing EPA to
             structure the program for 2006 on a national collective basis.  The statute
             has much more specific requirements for subsequent years. We are
             required to calculate the annual standard as explained in section 80.1105
             of the regulation.  Also see the answer to Question 11.9.
11.11  How do refiners meet blend mandates on the unleaded fuel sold to a wholesaler
      where the ethanol is blended at a fuel terminal?

      A:     The RFS program does not directly mandate blending.  Instead, it requires
             only that obligated parties such as refiners acquire sufficient RINs to
             offset their Renewable Volume Obligation (RVO).  Refiners can purchase
             ethanol, separate and retain the RINs, and then provide the ethanol to a
             terminal for blending. However, in the context of the RFS program,  the
             refiner need not track ethanol to the point of blending.  If a refiner, as an
             obligated party, wishes to utilize RINs acquired by an oxygenate blending
            facility, the refiner could negotiate a contract with the oxygenate blender
             (wholesaler in the question above) to acquire those RINs.

11.12  We are an association. Many of our members are blenders who are small and
      who find the attest engagement (audit) requirement difficult and expensive to
      comply with. We would like to engage a CPA who would be able to perform the
      required review of our members' records, in hopes of generating a cost savings to
      them. The following two part question is related to our handling of reporting and
      attest engagements on behalf of our members:
                                       47

-------
      a. Could we become the delegated authority for submission of reports on behalf
      of our members?

      A:     Individual blenders could rely on your association to submit reports to
             EPA on their behalf. .  However you should understand that if any reports
             are not submitted or are submitted improperly then responsibility would
            fall upon the individual blender.
      b. Could we hire a CPA and pay for the annual attest engagements for our
      members?

      A:     We also believe it may be appropriate for individual blenders to pay for
             CPA services through their association and recognize that this may result
             in a cost savings to them.  Section 80.125(a), which is referenced by
             80.1164, says: "Any [blender] subject to the [attest] requirements shall
             engage an independent certified public  accountant.... "Although his
             provision could be read to require that  a blender must have a contract
             with the CPA, EPA believes that the purpose of the attest requirements is
             that an attest is performed by an independent CPA that is given access to
             all necessary records, and in turn submits a report to EPA.  Whether the
             association or the blender pays the CPA is unimportant to EPA and if the
             association is capable of making a more cost-effective deal on behalf of its
             members, we believe that is appropriate.  However you should under stand
             that if the attest engagement is not performed or is performed improperly,
             responsibility would fall upon  the individual blender (ie., the regulated
             party).

11.13  Section 80.1164(a)(l)(ii) of the regulation states that the CPA conducting the
      attest engagement must obtain documentation of any volumes of renewable fuel
      used in gasoline during the reporting year; compute and report as a finding the
      volumes of renewable fuel represented in these documents. What does this mean?

      A:     This provision is intended to require the CPA to include in his or her
             report any volume of renewable fuel actually used in gasoline produced at
             the refinery or imported by the importer, but is not intended to include
             renewable fuels added at a terminal downstream. The requirement is part
             of the attest engagement because renewable fuels are to be excluded from
             the volume of gasoline used to determine the refiner's or importer's RVO.

11.14  What are the requirements for using an internal auditor for purposes of fulfilling
      the attest engagement requirement under the RFS rule rather than hiring a CPA?

      A:     The applicable regulations are in 40 CFR 80.125(d), which is referenced
             together with other general attest engagement requirements  in Section
             80.1164 of the RFS regulations..  This section provides that the attest
                                       48

requirement may be completed by an employee of the party if the

Auditors, Inc. ("CIA "); and 2) the CIA completes the internal audit in

Practice of Internal Auditing. The Codification of Standards is written
