     2.   WITH RESPECT TO TEACHERS INSURANCE AND ANNUITY ASSOCIATION OF AMERICA,

          PLEASE DISCLOSE THE FOLLOWING:

          o    THAT THE SELLING SHAREHOLDER PURCHASED IN THE ORDINARY COURSE OF
               BUSINESS; AND

          o    THAT, AT THE TIME OF PURCHASE OF THE SECURITIES TO BE RESOLD, THE
               SELLER HAD NO AGREEMENTS OR UNDERSTANDINGS, DIRECTLY OR
               INDIRECTLY, WITH ANY PERSON TO DISTRIBUTE THE SECURITIES.

          directly or indirectly, with any person to distribute the warrant or
          the underlying common stock.

Financial Statements for the Quarter Ended March 31, 2006
Note 4 -- Stock-Based Compensation, page F-36

     3.   WE HAVE REVIEWED YOUR RESPONSE TO COMMENT NINE. PLEASE PROVIDE US WITH
          A MORE DETAILED ANALYSIS TO HELP US UNDERSTAND THE TIMING OF THE
          INCREASE IN THE VALUE OF YOUR COMMON STOCK FROM $5.16 PER SHARE IN
          LATE JANUARY 2006 TO THE LOW END OF THE OFFERING RANGE OF $18 AS OF
          MAY 23. PLEASE IDENTIFY THE TIMING OF SPECIFIC EVENTS INDICATING THE
          INCREASE IN VALUE. PLEASE ALSO TELL US THE DATE OF THE INITIAL MEETING
          WITH YOUR UNDERWRITERS AND YOUR DECISION TO UNDERTAKE AN INITIAL
          PUBLIC OFFERING.

          The $5.16 exercise price used for the January 27, 2006 option award
          was equal to the per share purchase price received in the November 30,
          2005 offering of $90.3 million of common stock. The use of the same
          price also reflected continuing uncertainty at that time regarding the
          emergence of the ethanol industry, the extent to which blenders and
          refiners would adopt ethanol as a replacement for MTBE and volatility
          of ethanol prices.

          At its meeting on January 27, 2006, the Board of Directors received
          its first formal presentation from Morgan Stanley & Co. Incorporated
          and Lehman Brothers Inc., the managing underwriters, about the
          possibility of making a public equity offering. On March 22, 2006, the
          Board authorized the filing of the registration statement and other
          steps relating to the proposed public offering.

          Key events in the ethanol industry over the past ten months include:

          o    August 8, 2005 -- President Bush signs the Energy Policy Act of
               2005 (the "Energy Policy Act") into law. The Energy Policy Act
               provides for, among other things, Renewable Fuels Standards that
               create stated minimums for renewable fuel usage beginning in
               2006. The Energy Policy Act also eliminates the mandated use of
               oxygenates and does not provide any liability protection for
               blenders to ward off liability concerns regarding the use of
               methyl-tertiary butyl ether ("MTBE"), but does not ban the use of
               MTBE.

          o    January 29, 2006 -- In his State of the Union address, President
               Bush announces his support for renewable fuels and particularly
               ethanol. Shortly thereafter, several national publications issue
               articles about the ethanol industry.

          o    February 2006 -- Colonial Pipeline, a supplier of gasoline to the
               east coast, announces it will not ship MTBE-blended gasoline past
               May 5, 2006. Later this month, Colonial Pipeline reverses its
               decision and declares it will continue to support the shipment of
               MTBE-blended gasoline. This reflects the continuing uncertainty
               regarding the phase-out of MTBE.

          o    March 2006 -- Some Northeast gasoline suppliers announce they
               will continue to use MTBE rather than ethanol beyond May 5, 2006,
               again reflecting continuing uncertainty regarding the phase-out
               of MTBE.

          o    April 25, 2006 -- President Bush addresses the Renewable Fuels
               Association on the importance of the ethanol industry to the
               United States' energy policy. Significant positive press ensues.

          o    May 5, 2006 -- As part of the Energy Policy Act, the oxygenate
               requirement expires. As a result, blenders begin using ethanol as
               a replacement for MTBE nationwide because of health and liability
               concerns while still meeting various state and federal emissions
               standards. While the ethanol industry had expected the phase-out
               of MTBE and increased usage of ethanol after the passage of the
               Energy Policy Act, there was an abrupt shift by blenders and
               refiners in favor of ethanol over MTBE.

          o    May 19, 2006 -- The top three U.S. automakers address Congress in
               favor of the increased production of flexible fuel vehicles
               (which operate on E85 fuel) and endorse a plan that would require
               renewable fuels to constitute 25% of the U.S. transportation
               energy needs by 2025.

          The net result of the events described above has been a steep increase
          in the price of ethanol between March 31, 2006 and May 24, 2006. The
          following chart shows the Chicago Board of Trade futures prices for
          June 2006 delivery contracts in recent periods:

                                    [CHART]

          As illustrated above in the CBOT data, ethanol futures prices
          increased dramatically in May 2006. As a result of high prices and
          strong demand for ethanol, the Company significantly increased its
          forecasted results for the year. This increase, combined with
          increased investor interest in ethanol, resulted in the higher
          expected valuation and, consequently, the anticipated price range for
          the offering.

     4.   PLEASE TELL US HOW YOU DETERMINED THE CHARGE RECORDED IN THE FIRST
          QUARTER RELATED TO THE PUT WARRANT, INCLUDING THE VALUE OF THE
          UNDERLYING STOCK USED IN THE CALCULATION OF THE VALUE OF THE PUT
          WARRANT AS OF DECEMBER 31, 2005 AND MARCH 31, 2006. IN YOUR RESPONSE,
          PLEASE ADDRESS THE IMPACT OF THE INCREASE IN THE VALUE OF YOUR COMMON
          STOCK DURING 2006 ON YOUR ACCOUNTING FOR THE PUT WARRANT. IN THIS
          REGARD, WE NOTE THAT DURING THE FIRST QUARTER OF 2006 YOU RECORDED A
          CHARGE RELATED TO THE INCREASE IN THE VALUE OF YOUR COMMON STOCK OF
          $0.051 PER SHARE.

          As discussed yesterday with the Staff and as illustrated in the
          materials submitted to the Staff yesterday, the valuation of the put
          warrant at December 31, 2005 was based upon a third-party valuation of
          our common stock of $6.33 per share (which does not include any
          discount for liquidity of a private company stock). For the valuation
          as of March 31, 2006, the Company used the same valuation methodology
          and updated pricing assumptions to estimate the value of the common
          stock at $6.38 per share, with a corresponding increase in forecasted
          EBITDA and resulting increase in the valuation of the put warrant.
          This relatively minor change in value reflects improving market
          conditions, but also takes into account uncertainty around that
          timeframe regarding the emergence of the ethanol industry, the extent
          to which blenders and refiners would adopt ethanol as a replacement
          for MTBE and volatility in ethanol prices, as discussed in the
          Company's response to comment no. 3 above.

     5.   PLEASE TELL US WHAT PORTION OF THE NOVEMBER 30, 2005 OFFERING OF YOUR
          COMMON STOCK WAS TO RELATED PARTIES.

          Of the $90.3 million of common stock sold in the November 30, 2005
          offering, approximately $58 million was purchased by the Company's
          directors, officers, Bluestem Funds (an existing private equity
          investor in the Company) and their affiliates. Eos Funds, a group of
          funds managed by a private equity firm, after completing their own due
          diligence, made their first investment in the Company, purchasing for
          cash $30 million of the common stock offered. Teachers Insurance and
          Annuity Association of America, a large institutional investor,
          purchased substantially all of the remainder of the offered common
          stock for cash.

     6.   PLEASE PROVIDE US WITH ADDITIONAL INFORMATION TO HELP US UNDERSTAND
          HOW YOU DETERMINED THE AMOUNT OF THE $29.5 MILLION CHARGE TO BE
          RECORDED IN CONNECTION WITH YOUR INITIAL PUBLIC OFFERING RELATED TO
          THE MANAGEMENT BONUS, THE PUT WARRANT, AND THE ACCELERATION OF
          OPTIONS, WARRANTS AND RESTRICTED STOCK. PLEASE ADDRESS EACH COMPONENT
          OF THIS CHARGE INDIVIDUALLY.

          The $29.5 million charge consists of the following three items:

          o    Put warrant expense of $14.9 million -- The Company estimates it
               will incur $14.9 million in expense in connection with the put
               warrant, which is exercisable for 1,180,000 shares of common
               stock. This expense will be incurred to mark the put warrant to
               the assumed initial public offering price of $19.00 per share. As
               of March 31, 2006, the value of the put warrant was



Pamela A. Long

               estimated based upon a $6.38 per share valuation, as noted in the
               Company's response to comment no. 4 above.

          o    Compensation expense of $1.3 million for the grant of shares to
               non-management employees -- In connection with the completion of
               the offering, the Compensation Committee has approved grants to
               certain non-management employees, totaling $1.3 million of shares
               of common stock. Based on an assumed initial public offering
               price of $19.00 per common share, this would equate to 66,789
               shares of common stock. The estimated compensation expense is
               based upon the total dollar amount of the shares being granted.

          o    Compensation expense of $13.3 million for the vesting of
               outstanding options and warrants -- In connection with the
               completion of the offering, substantially all of the outstanding
               options and warrants to purchase the Company's common stock will
               become immediately exercisable due to accelerated vesting
               provisions within those instruments. For options and warrants
               which had a measurement date prior to March 31, 2006, the
               remaining unrecognized compensation costs of $4.1 million, as
               previously computed under FAS 123R as of March 31, 2006, was
               included as the amount to be expensed at the initial public
               offering date. For 640,041 stock options as to which the initial
               public offering date will become the measurement date, the
               Black-Scholes model was used to determine the fair value of the
               options, based upon the assumed initial public offering price of
               $19.00 per common share, resulting in an additional expense of
               $11.3 million, for a total of $15.4 million in expense related to
               accelerated vesting of options and warrants. A 35% tax benefit
               related to the non-qualified stock options was included in the
               computation, for a tax benefit of $2.1 million.

Exhibits

     7.   PLEASE NOTE THAT WE WILL REVIEW THE LEGALITY OPINION WHEN IT IS FILED
          AND MAY HAVE COMMENTS. PLEASE ALLOCATE SUFFICIENT TIME TO PERMIT OUR
          REVIEW PRIOR TO REQUESTING ACCELERATION OF EFFECTIVENESS.

          The Exhibit 5.1 legal opinion has been filed with Amendment No. 3.

     8.   PLEASE FILE THE AGREEMENT WITH AMERICAN MILLING, LP AS AN EXHIBIT TO
          THE REGISTRATION STATEMENT OR TELL US WHY SUCH AGREEMENT NEED NOT BE
          FILED.



Pamela A. Long

          The Company does not believe the agreement with American Milling, LP
          ("American Milling") is a material contract for purposes of Form S-1
          because the Company has no legal obligation to pay consideration to
          American Milling unless the Company accepts a development site. The
          Company is uncertain as to how many sites it will accept from American
          Milling, if any.

The Company is eager to commence marketing of the offering this week prior to
the Memorial Day holiday weekend. Please address any questions or comments you
may have about this letter or Amendment No. 3 to me at (503) 294-9448.

Very truly yours,
