5.Schedule

5.1Schedule:  Kiewit guarantees that Substantial Completion of the Work will be achieved no later than, the later of (i) *** or (ii) ***, (“Guaranteed Substantial Completion Date”). Owner will not provide Kiewit the Notice to Proceed until the Air Permit is issued and any permits or approval necessary to provide reasonably unrestricted access to the Plant Site in order for Kiewit to be able to perform the Work are issued and/or obtained.   In the event of a delay in Substantial Completion not permitted by the terms of this Contract, except as otherwise set forth in this Section 5.1, Kiewit’s sole and exclusive liability and Owner’s sole and exclusive remedy for such delay shall be:  (i) Days 1 – 30, $ ***, (ii) Days 31 – 60, $ ***, and (iii) Days 61 plus, $ *** (the “Base LDs”); provided, however, in the event any such delay in Substantial Completion is due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T, then, except as otherwise set forth in this Section 5.1, Kiewit’s sole and exclusive liability and Owner’s sole

12

and exclusive remedy for such delay shall be *** per Day (the “Reduced LDs”) commencing on the 31st Day after the Guaranteed Substantial Completion (the “Reduced LD Date”) (unless (x) during the thirty (30) day period between the Guaranteed Substantial Completion Date and the Reduced LD Date a problem arises due to Owner (other than Owner’s exercise of its rights under this Contract) which prevents reaching Substantial Completion by the Reduced LD Date in which event the Reduced LD Date will be extended by the number of days such problem causes Substantial Completion not to be achieved or (y) on the Reduced LD Date Substantial Completion has not been achieved due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T involving a delay in equipment delivery beyond Delta-T’s control (including a delay in delivery of replacement equipment beyond Delta-T’s control which replacement equipment was due to equipment failure) in which event the Reduced LD Date will be extended until such equipment is delivered to the Plant Site); provided further; however, in the event any such delay in Substantial Completion is due both to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T and also to other reasons for which the Base LDs would apply (the “Base LD Causes”), then until such time as the Base LD Causes are remedied such that the only remaining reason, if any, Substantial Completion is not achieved is due to a defect in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T, then the Base LDs shall be paid by Kiewit to Owner and not the Reduced LDs, and once such Base LD Causes are so remedied, if the defects in Delta-T’s scope of work under Kiewit’s subcontract with Delta-T have not been remedied so that Substantial Completion has not yet been reached, then the Reduced LDs shall be paid by Kiewit to Owner until Substantial Completion is reached.  In addition to the foregoing, and notwithstanding any other provision of this Contract, but subject to Section 16.1, in the event Substantial Completion is not reached by the Guaranteed Substantial Completion Date, Kiewit and Owner agree to work together and with Delta-T in a commercially reasonable and expeditious manner in order to reach Substantial Completion at the earliest possible time.  Kiewit shall use all reasonable efforts to comply with Owner’s wishes with respect to changes in Schedule, but any i) material adjustment requested by Owner to the Schedule; or ii) Owner’s

13

inappropriate disapproval of deliverables as more fully set forth in Section 11.3.2, shall be deemed a change and Kiewit shall have no obligation to slow down or accelerate its performance of the Work except in accordance with Article 6 below.

5.2Threshold.  Upon obtaining Substantial Completion, Kiewit shall have *** days thereafter to increase the output of merchantable ethanol product of the Plant from *** of the Nameplate to *** of the Nameplate (*** per year of undenatured ethanol) (the “Threshold”).  However, so long as Kiewit is working diligently and in good faith to reach the Threshold, Owner shall agree to reasonable extensions of said *** day period.

5.3Early Completion Bonus.  If Substantial Completion of the Plant is attained prior to *** months after the date of the issuance of the Notice to Proceed, Owner shall pay Kiewit at the time of Final Payment an early completion bonus equal to *** of the equivalent of delay liquidated damages rate, had the Work been that same number of Days late for each Day that Substantial Completion occurred prior to said date.  In no event shall the early completion bonus exceed ***.

6.Changes

6.1Issuance of Change Orders by Owner:  Owner may by its written order require changes in the Work within the general scope of the Contract consisting of additions, deletions or other revisions, provided that the Contract Sum and payment schedule are adjusted to reflect the change in Kiewit’s direct and indirect costs resulting from such changes, plus a reasonable amount for profit, and that the time allowed for completion, warranty obligations, and any other obligations of Kiewit affected by the changes are adjusted to cover the consequences to Kiewit resulting from such change.  Kiewit shall have the right to request a claim for such adjustments to the extent the cumulative impact of such changes can reasonably be demonstrated.  The amount to be paid to Kiewit, the effect on the Schedule, if any, and any other adjustments to the Contract will be made by mutual agreement.

14

Maximum *** BTU HHV per gallon (average) of un-denatured fuel ethanol produced for gas-fired boilers and gas fired ring dryers based on natural gas provided at a minimum gas quality of *** BTU per standard cubic foot (1atm, 70° F), and *** to *** maximum (weight) DDGS moisture content.

7.4Condition to Performance Guarantees.  If any breach of warranty under this Contract or failure to meet the Performance Guarantees under this Contract is the result of:

18

7.4.1       The feedstock provided by Owner, not being in compliance with the conditions described in Section 7.3.1 or 7.3.2, as applicable;

7.4.2       Abuse, or poor maintenance, of the Equipment;

7.4.3       Owner’s failure to fulfill any of its obligations, which individually or in the aggregate are material, under the Performance Test protocols set forth in Exhibit C;

7.4.4       Owner’s failure, in any material way, to operate the Plant in accordance with the operating manuals and instructions provided by Kiewit;

7.4.5       Owner designing or procuring equipment and systems, other than under this Contract, that fail to meet Delta-T’s basic process design specifications for energy efficiency;

7.4.6    Owner fails to provide electrical service with at least a 0.85 power factor;

then Kiewit shall notify Owner, Owner shall take the necessary corrective actions and the affected Performance Tests shall be re-run at Owner’s expense.  However, if Owner refuses or fails  to provide the requested items, then Kiewit shall have no obligation or liability for any such breach of the applicable warranty or Performance Guarantees under this Contract.

7.5Substantial Completion:  Substantial Completion shall be achieved when the requirements for Substantial Completion in Exhibit E have been satisfied.  Kiewit shall provide Owner a certificate of Substantial Completion certifying that all requirements for Substantial Completion have been met at the time when all requirements for Substantial Completion have been achieved.  Owner shall have three (3) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Substantial Completion has been achieved.  Owner shall specify in detail any requirements for Substantial Completion which it believes Kiewit has failed to achieve within seven (7) Business Days after receipt of such certificate.  Substantial Completion shall be deemed to have occurred on the date when the last of the requirements for Substantial Completion has been achieved.  Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take

19

whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach Substantial Completion; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve Substantial Completion; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

7.6          Cure:  After Substantial Completion (at which point care, custody and control transfers to Owner in accordance with Article 13), Owner shall allow Kiewit reasonable access to the Plant.  After reaching Substantial Completion, Kiewit agrees that Kiewit, at Kiewit’s sole cost and expense, shall take whatever action is reasonably necessary and consistent with sound engineering practices to cause the Plant to reach the Threshold; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Threshold; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects.

After reaching the Threshold, Kiewit shall, for a period of up to six (6) months thereafter and subject to Section 16.1, (i) use good faith efforts to  cause the Plant to satisfy the Performance Guarantees in Section 7.3 and to re-run the Performance Tests as needed during that period; provided, Kiewit shall not, except as set forth in Section 16.1 below, be responsible for costs associated with any defects in Delta-T scope of work under Kiewit’s subcontract with Delta-T which result in failure to achieve the Performance Guarantees; Kiewit shall, however, be responsible for any costs which are reimbursed to Kiewit by any manufacturer or supplier associated with such defects, and (ii) complete all Punch List items to the reasonable satisfaction of Owner.  Kiewit shall have the foregoing period of time in which to satisfy the obligations in the preceding sentence before being subject to paying any liquidated damages.

Kiewit is obligated to continue all aspects of the Work necessary to achieve completion of Performance Tests, Substantial Completion, the Threshold, and Final Acceptance (and in connection therewith, Kiewit is obligated to expend all necessary

20

funds, devote all necessary time, and provide or procure all necessary work, materials, labor and services), except as such obligation is limited by Section 16.1 below.  All cost and expense associated with meeting such obligation, including any necessary acceleration of the rate of work will, unless and except to the extent required in accordance with Article 6, be for Kiewit’s account.

7.7Liquidated Damages and Maximum Damages for Performance Guarantees:  If the Plant has achieved Substantial Completion and Threshold, but has not achieved one or more of the Performance Guarantees set forth in Section 7.3 above during a Performance Test as provided herein, and Kiewit has not been able to correct the defect and pass all components of the Performance Tests within the time set forth at Section 7.6 above, then Kiewit shall pay to Owner liquidated damages based on the net amount (i.e. the amount of damages in each case for which damages apply shall be netted against the countervailing factor in each case for which the countervailing factor applies, to determine the final net performance liquidated damages if any) due as set forth in Section 7.8 below up to a maximum cumulative amount in accordance with Article 16 of the General Conditions of this Contract.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, except as such obligation is limited by Section 16.1.  For the avoidance of doubt, the countervailing factors shall not be taken into account for the purposes of determining whether Substantial Completion or the Threshold has been achieved.  Kiewit shall pay such liquidated damages no later than the date that is six (6) months after the achievement of the Threshold.

The sum of the countervailing factors, determined as set forth under Section 7.8 below, shall be deducted from the sum of the damages determined thereunder.  In no case, however, shall Owner have any obligation to pay Kiewit as a result of such calculation.  If the countervailing factors are greater than the damages, the performance liquidated damages shall be deemed to be zero.

21

7.8Amount of Damages and Countervailing Factors

Fuel Ethanol Yield:	*** per *** pounds of anhydrous undenatured ethanol (average per ASTM D4806-06) per pound of dry fermentable starch that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Yield listed in Section 7.3.1 above. To the extent the yield is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall be a countervailing factor. For purposes of calculating damages as set forth above, damages shall be measured in increments of .001. An increment of .0005 or less is rounded down. An increment of .0006 or above would be rounded up.
Fuel Ethanol Production Rate:	*** per 10 US gallons per hour of anhydrous undenatured ethanol (average per ASTM D4806-06) that the Performance Test results show lower or higher than the guaranteed Anhydrous Fuel Ethanol Production Rate listed in Section 7.3.1 above. To the extent the rate is lower the resulting number shall constitute damages. To the extent that it is higher the resulting amount shall not be a countervailing factor.
Natural Gas Consumption:	*** *** *** ***

7.9Damages Reasonable:  The Parties acknowledge and agree that the terms of this Contract with respect to liquidated damages, including those payable under this Article 7, are fair and reasonable considering the damage Owner would sustain in the event of the failure of the Plant to meet the Performance Guarantees set forth in Section 7.3 above, that such damages have been agreed upon and fixed as liquidated damages because of the difficulty of ascertaining as of the date hereof the exact damages that would be sustained by Owner, and that such liquidated damages provisions shall be applicable regardless of the actual amount of damages sustained.  All amounts shall be paid as liquidated

22

damages and not as a penalty.  The Parties specifically waive the right to challenge the liquidated damages rates and limits provided herein.  Notwithstanding the foregoing limitations on damages for failure to reach the Performance Guarantees, Kiewit shall be obligated to continue all aspects of the Work necessary to achieve the Performance Guarantees, subject to the limitations set forth in Section 16.1.

7.10Performance Bonus:  Upon Final Acceptance, Kiewit and Owner shall cooperate during a six-month bonus period of operation.  Owner agrees to pay to Kiewit a bonus of *** for each *** above *** of Nameplate, capped at a bonus of ***; provided that the Plant meets the requirements of all applicable permits required for the operation of the Plant on a continuous basis (e.g. if there is an annual limit on emissions, the operation of the Plant at the levels during the applicable period, if operated on a continuous basis for a year, would meet the applicable annual emissions requirements).  Kiewit has six (6) months from Final Acceptance to achieve this bonus.  The bonus shall be determined by reviewing operating data on rolling two-week periods commencing on the date of Final Acceptance.  Bonus shall be payable thirty (30) Days after achieving these bonus criteria.

7.11Training of Owner’s Personnel:  Kiewit shall provide the training described in Exhibit A.  Owner shall provide appropriate personnel, and Kiewit shall provide such training, at times mutually agreed by them, commencing prior to Commissioning in sufficient time to prepare Owner’s employees to perform Commissioning and Startup and to perform their obligations with respect to the Performance Test.

7.12Use of Plant Prior to Final Acceptance:  Owner may use the Plant for commercial purposes on or after the achievement of Substantial Completion.  If Owner elects to use any portion of the Work for commercial purposes prior to Final Acceptance, it shall allow Kiewit reasonably unrestricted access to the Plant to do all things required to be done to complete the Punch List and achieve Final Acceptance and to meet full Performance Guarantees, as long as such access does not unreasonably interfere with Owner’s use of the Plant for commercial

23

purposes.  In the event Owner fails to comply with its obligation to provide Kiewit access to the Plant as set forth in the preceding sentence, (i) for each day that Owner so fails to provide such access, Kiewit shall have an additional day to satisfy its obligations hereunder which were adversely affected by Owner’s failure to so provide such access and (ii) if such failure to so provide such access is for an aggregate of thirty (30) days, then at the end of such thirty (30) aggregate day period, if Final Acceptance has not yet occurred, the matters set forth in items (i), (ii) and (iii) of the definition of Final Acceptance shall be deemed to have occurred.

7.13Final Acceptance:  Kiewit shall provide Owner a certificate of Final Acceptance certifying that all requirements for Final Acceptance have been met at the time when all requirements for Final Acceptance have been achieved.  Owner shall have ten (10) Business Days after receipt of such certificate to advise Kiewit as to whether it agrees Final Acceptance has been achieved.  Owner shall specify in detail any requirements for Final Acceptance which it believes Kiewit has failed to achieve.  Final Acceptance shall be deemed to have occurred on the date when the last of the requirements for Final Acceptance has been achieved.

8.Price and Payment

8.1Contract Sum:  Owner will pay Kiewit for the full and satisfactory completion of the Work the Contract Sum of ***, or such other sum as may be adjusted in accordance with this Contract, plus Excluded Taxes required under applicable laws to be paid or remitted by Kiewit in connection with the Work.  Owner shall be credited against the Contract Sum with all amounts paid by Owner or its affiliates under the AWA and the Pre-EPC Agreement.  The Contract Sum includes the cost of materials and Equipment described in the AWA and the Pre-EPC Agreement to the extent such materials and Equipment are incorporated into the Work.  In addition, the Contract Sum includes allowances for each of the matters (and for the amounts) set forth on Exhibit P.  The Contract Sum shall be adjusted for (a) preliminary site Work and piling Work according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such preliminary site Work and piling Work plus a

24

markup of *** and (b) all other Work set forth on Exhibit P (i.e. other than preliminary site Work and pilings Work) according to the difference between (i) the estimate for such Work set forth on Exhibit P and (ii) Kiewit’s actual costs of performing such Work (without any markup).  All matters covered under the AWA and Pre-EPC Agreement are superseded by the provisions of this Contract and are covered hereby.  The license fee to be paid by Owner under the License Agreement shall be paid by Owner directly to Delta-T and is not included in the Contract Sum.  If the Notice to Proceed is provided more than ninety (90) days after the execution date of this Contract, the Contract Sum and the Guaranteed Substantial Completion Date shall be subject to equitable adjustment in accordance with Article 6.

The Contract Sum does not include Excluded Taxes.  Excluded Taxes means any: (i) taxes imposed by any Governmental Entity on the gross receipts earned by, or paid to, Kiewit on the Contract Sum or any other amounts to be paid by Owner to Kiewit hereunder or any portion of such amounts thereof, (ii) sales or use taxes imposed on Kiewit or any of its Subcontractors for purchases or sales of Equipment or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site or (iii) any property taxes imposed directly or indirectly by any Governmental Entity on the Plant, Equipment, or any other materials to be installed in, affixed to, or incorporated into the Plant or the Plant Site; provided, however, Excluded Taxes do not include any tax based on the net income of Kiewit or its Subcontractors.  If Kiewit or any of its Subcontractors are, now or in the future, required to collect from Owner or pay any Excluded Taxes with respect to all or any part of the Work (other than any such tax based on income), then that amount shall be paid by Owner at Kiewit’s request, in addition to the Contract Sum.  Kiewit shall (and shall make a good faith effort to cause its Subcontractors to) cooperate with and provide reasonable assistance to Owner in obtaining any exclusions, exemptions or credits from any Excluded Taxes and to minimize said Excluded Taxes.  Owner shall hold harmless, defend and indemnify Kiewit and its Subcontractors for, and reimburse to Kiewit or any of its Subcontractors, any Excluded Taxes, interest or penalties associated therewith, or any other amounts, that must be paid by Kiewit or any of its Subcontractors as a result of an assessment or other action by a Governmental Entity as the result of Kiewit’s or Kiewit’s Subcontractors’

25

reliance upon Owner’s claims of entitlement to any exemptions or reductions of Excluded Taxes.  Upon Kiewit or any of its Subcontractors receiving any such assessment or notice of any such other action by a Governmental Entity, Kiewit shall, and shall cause its Subcontractors to, promptly notify Owner of same.  Upon Owner’s receipt of such notice from Kiewit or its Subcontractors, Owner shall undertake the defense of any such assessment or other action by the applicable Governmental Entity, and Kiewit shall, and shall cause its Subcontractors to, cooperate with Owner in such defense.  Owner shall have the right to control such defense of any such assessment or other action by the applicable Governmental Entity.  A preliminary listing of available tax exemptions and concessions expected to be applicable to or available to the construction or operation of the Plant is attached hereto as Exhibit Q.

If Kiewit or any of its Subcontractors are required by applicable laws or are otherwise required to pay Excluded Taxes, Kiewit shall include requests for payment or reimbursement of such Excluded Taxes with Applications for Payment, the Final Payment, or any time within ninety (90) Days of a requirement by a Governmental Entity to pay such Excluded Taxes.

8.2Termination Fee:  In the event that Owner exercises a right to terminate under Section 9.4, or in the event that Kiewit terminates this Contract under Section 9.3 (provided the suspension of the Work which resulted in such termination by Kiewit does not include a suspension due to a Force Majeure Event),  the Owner shall pay in addition to sums due under Section 9.4 of the General Conditions, a fee determined as follows, as a liquidated damage for lost opportunity cost and not as a penalty: 

Termination:	Termination Fee as a Percentage of Total Contract Sum
Within Ninety (90) Days after the Date of Commencement	***
From Ninety-one (91) to one hundred fifty (150) Days after the Date of Commencement	***
From One hundred fifty-one (151) to two hundred ten (210) Days after the Date of Commencement	***

26

8.3Payment Terms:  Owner shall provide a mobilization payment to Kiewit in accordance with and at the times set forth in Exhibit B.  Owner shall make monthly progress payments according to percentage of completion beginning with and including payments made for work done under the AWA or Pre-EPC Agreement as set forth on Exhibit R, which payment schedule shall reflect the concept of “cash neutrality”.  For purposes of this Contract, “cash neutrality” shall mean that Kiewit will not be required to be out of pocket at any time for any amounts owed by Kiewit for the Work and that Kiewit shall not be paid by Owner for the Work in advance in such a manner that would result in Kiewit being cash positive as reasonably estimated by Owner and Kiewit. In the event the payment schedule set forth on Exhibit R conflicts with the foregoing definition of Cash Neutrality, the parties agree to conform said exhibit accordingly.  Kiewit shall submit Applications for Payment in the form set forth at Exhibit B.1, together with reasonable supporting documentation for said Application, to Owner.  Owner shall, through Owner’s Representative, sign the Certificate for Payment set forth on the Application for Payment for the full payment applied for, unless it believes that all or any part of such amount is not then due.  If Owner believes all or part of the amount requested in the Application for Payment is not then due, Owner shall amend the Application for Payment contained therein by indicating the amount, if any, that it believes to be due, and shall sign the application as amended and deliver the certificate, together with written notice of Owner’s reasons for certifying less than the whole amount applied for.  Retainage for each payment shall be *** for a 108 MGY plant; provided however, that Kiewit may provide an adjustable and irrevocable letter of credit in lieu of retainage in a form reasonably acceptable to Owner.  There shall be no retainage for Equipment that was the subject of the AWA.    In addition, upon payment of *** of the Contract Sum (excluding payments for Equipment that was the subject of the AWA), and provided Kiewit is in material compliance with this Contract, there shall be no retainage on any further payments under this Contract.  Upon reaching the Threshold, and provided Contractor is in material compliance with this Contract, Owner shall release the retainage in exchange for Kiewit providing Owner a letter of credit for an amount equal to *** of the agreed upon estimated value of the

27

cost of completion of Punch List items plus any potential liability of Kiewit for liquidated damages.  Owner shall wire transfer, in immediately available funds, all amounts for which it has issued certificates, within fifteen (15) Business Days of the date of its receipt of the Application for Payment, to a bank account to be selected by Kiewit.  If Owner does not certify payment in the amount of the Application, and Kiewit and Owner cannot agree on a revised amount within five (5) Business Days of the date of the Owner’s submittal of the amended Application for less than the full amount, then either Party may commence the Dispute Resolution process in accordance with Article 18.  In any case, when the reasons stated by Owner for withholding payment of any amount for which an application has been made are removed to Owner’s reasonable satisfaction, in whole or in part, Owner shall immediately issue a Certificate for Payment for the amount withheld (to the extent the reason stated for withholding is removed) and make payment, via wire transfer as described in this Section 8.3, of the amount so certified on or before the date that the next payment is due.

8.4Late Payment:  Late payments by either Party shall bear interest at the rate of Wall Street Journal prime rate plus two percent (2%).

8.5Mechanic’s Lien Waivers and Indemnity:  Kiewit shall pay promptly for all amounts due for all materials, labor, Service and Equipment used in or in connection with the performance of this Contract, including those of its Subcontractors, when bills or claims become due, and shall indemnify and hold harmless Owner from and against all claims of its Subcontractors.  Owner shall give Kiewit prompt notice of any such claim upon receipt by Owner of any such claim.

8.6Mechanic’s Liens:  Kiewit shall keep the Plant Site and any other adjacent real property owned or leased by Owner and all other property of Owner which is located on the Plant Site or such adjacent real property, free and clear of laborer’s, materialmen’s and mechanic’s or similar type liens arising out of the performance of the Work, unless Owner fails to make required payments to Kiewit as set forth in this Article 8 and then only to the extent Owner has failed to make such payments.  Owner shall promptly notify Kiewit in writing of any lien so

28

arising of which it has notice or knowledge.  Kiewit shall provide to Owner as a condition to payments to be made pursuant to Article 8, a partial release of lien in the form of Exhibit B.2.1 duly executed by Kiewit and any major Subcontractors (those with subcontracts having a value of over $500,000) and shall also obtain and timely provide a complete release of lien and general release with respect to any such subcontract for which full and final payment is made, in the form of Exhibit B.2.  In each case, the release of lien may be for an amount less amounts that will be paid from the payment for which such release of lien is requested.  Kiewit shall promptly pay each Subcontractor upon receipt of payment from Owner of the amount invoiced that is undisputed and due to such Subcontractor.

If notwithstanding the foregoing, a lien is attached to the Plant, or the Plant Site, or any part thereof, without limiting any other rights of Owner, Owner shall have the right, at its option, to take all action reasonably necessary to discharge such lien upon thirty (30) days prior written notice to Kiewit of such lien.  Kiewit shall reimburse Owner for all amounts expended by Owner to obtain such discharge, including all costs and attorney’s fees and expenses and Owner shall have the right to deduct such amounts from payments otherwise due to Kiewit which will be debts due and payable by Kiewit to Owner.

8.7Final Payment:  Kiewit shall invoice Owner for the final amount due to it under this Contract upon reaching Final Acceptance.  Payment of all of the Contract Sum remaining unpaid, and any and all other amounts owing to Kiewit under the Contract (less and except any amounts owed by Kiewit to Owner), shall be made within thirty (30) Days after Final Acceptance and receipt by Owner of a final invoice; provided, that such payment shall not become due until Kiewit submits to Owner an affidavit in form and substance reasonably satisfactory to Owner that all payrolls, undisputed amounts owed to Subcontractors, suppliers and materialmen and any other indebtedness which might be or give rise to a lien against the Plant or the Plant Site arising out of performance of the Work or any portion thereof have been paid.

29

8.8Effect of Payment

No payment, final or otherwise or verification under this Article 8, shall constitute a waiver of claims by Owner or constitute or be deemed an acceptance, in whole or in part, of any portion of the Plant not in accordance with this Contract.

Upon receipt by Kiewit of payment in respect of the final Application for Payment pursuant to Section 8.7 (“Final Payment”), Kiewit releases Owner from any claim for payment for the Work.  For the avoidance of doubt, the sums paid to Kiewit in respect of its final Application for Payment pursuant to Section 8.7 shall constitute a valid and binding Final Payment for the purposes of this Section 8.8.

8.9Set-Off

Owner may deduct from moneys otherwise due to Kiewit:

(i)any debt or other moneys due from Kiewit to Owner in relation to the Contract; and

(ii)any claim to money which the Owner may have against the Kiewit whether for damages (including liquidated damages) or otherwise, under this Contract or otherwise at law relating to the Work.

9.Rights of Owner and Kiewit to Suspend Work or Terminate

9.1Owner’s Right to Terminate For Cause:  Owner may terminate this Contract if Kiewit commits or is subject to (a) voluntary bankruptcy, liquidation, reorganization or insolvency; (b) involuntary bankruptcy liquidation, reorganization or insolvency; (c) false or materially misleading representation or warranty; (d) assignment or transfer without permission; (e) failure to maintain insurance coverage as required; (f) failure to comply with any applicable law or permit; (g) cessation or abandonment of the Services (unless due to an emergency and then only for the duration necessitated by the emergency or due to Owner’s failure to make payment as required); (h) failure to supply sufficient skilled workers or suitable materials and equipment; (i) failure to achieve Substantial Completion within one hundred eighty (180) Days of the Guaranteed Substantial Completion Date; (j) failure to perform or observe any other material provision of this Contract; or (k) termination or repudiation of the EPC Guaranty

30

or voluntary or involuntary bankruptcy or insolvency of the guarantor under the EPC Guaranty; and, in the case of (c), (e), (f), (g), (h), or (j), Kiewit fails to cure such breach within thirty (30) Days (or such longer period (not to exceed one hundred eighty (180) Days) in the case of (e), (f), (h) or (j)) from written notice of such breach as may be commercially necessary.

Upon such termination Owner may take possession of the Work completed by Kiewit or delivered to the Plant Site and all materials and Equipment at the Plant Site acquired for incorporation into the Work and owned by Owner or Kiewit, take assignment of all purchase orders and subcontracts related to the Work and complete the Work by whatever reasonable method Owner may deem expedient.  Owner shall permit Kiewit access to the Plant Site after such termination as reasonably required by Kiewit to remove any equipment, trailers, supplies, goods and materials maintained by Kiewit in connection with the Work but not intended to be incorporated into the Plant, or owned or used by any of its Subcontractors under subcontracts not to be assigned to Owner.  In the event of termination for any of the reasons set forth above, Kiewit will be liable to Owner for any reasonable costs incurred by Owner to build the Plant as specified, in excess of the Contract Sum, up to a maximum of one hundred percent (100%) of the Contract Sum.  In case of such termination, the license granted under Section 2.4 above shall remain effective.

9.2Kiewit’s Right to Suspend Work:  If Owner does not pay Kiewit amounts that Owner has certified in writing for payment by the date such payment is due, then Kiewit may, upon fifteen (15) Days written notice to Owner, suspend the Work until payment of the amount owing has been received.  If Kiewit suspends the Work under this Section 9.2, then Kiewit shall be entitled to a change order in accordance with Article 6.

9.3Kiewit’s Right to Terminate:  Kiewit may terminate the Contract on fifteen (15) Days written notice to Owner if the Work is suspended, without fault on the part of Kiewit or, any of its Subcontractors, for more than one hundred eighty (180) consecutive Days.  In such event the termination shall be treated as if it were a termination for convenience by Owner, in accordance with Section 9.4, except that no Termination Fee shall be owed under Section 8.2 if such suspension

31

which resulted in such termination included a suspension due to a Force Majeure Event.

9.4Termination for Convenience by Owner.  Owner shall have the right, in its sole discretion, to terminate this Contract for convenience by giving written notice to Kiewit, but in the event of such termination for convenience, Owner will not enter into a contract with another person or entity to construct the Plant.  Upon such notice Kiewit shall immediately stop work and take all necessary and prudent actions to protect and preserve the Work, and to minimize Owner’s costs in terminating the project at that stage of completion.  Upon such termination Owner shall pay Kiewit (a) all amounts then due to it under this Contract as of the date of termination, including all amounts completed but not yet invoiced, and including the portions, if any, of such amounts that would have been held as retainage in accordance with Section 8.3 (or shall release the letter of credit in lieu of retainage, or the Punch-list letter of credit as applicable),  (b) all unavoidable costs payable to Subcontractors, including, without limitation, fees for cancellation or breakage costs, and Kiewit’s costs of demobilization, and (c) a termination fee calculated as set forth in Section 8.2, but in no event shall the total of such amounts set forth in Paragraphs (a) - (c) above exceed the Contract Sum.  For this purpose, the amounts then due to Kiewit shall be deemed to be all amounts billed in accordance with Exhibit B up to the date of termination, plus the value of all goods delivered and services performed under this Contract and not billed as of the date of termination less any amounts which have been prepaid by Owner for said items.  In the event that the Parties cannot agree on the total amount due within thirty (30) Days of the date of Kiewit’s demand for payment hereunder and delivery by Kiewit to Owner of all backup documentation supporting the amounts claimed to be owed by Kiewit, either Party may initiate the Dispute Resolution process set forth in Article 18 below.

9.5Owner’s Right to Suspend.  Owner shall have the right, in its sole discretion to suspend work under this Contract for periods of time up to one hundred eighty (180) days individually and in the aggregate.  In such event, Kiewit shall be entitled to an equitable adjustment to the Contract Sum and to the Schedule in accordance with Article 6 herein, including, but not limited to, an adjustment for

32

costs of escalation for labor and materials, unless such suspension is due to the failure of Kiewit or its Subcontractors to act in accordance with Good Industry Standards in the performance of their obligations under this Contract.

10.Safety and Security

10.1Premises:  Kiewit will keep the Plant Site clean and orderly and will insure that its Subcontractors do likewise.  At completion of the Work, Kiewit shall leave the Plant Site clean of all debris resulting from performance of the Work and in an orderly condition, to enable safe and reliable operation of the Plant in accordance with Applicable Laws.

The review and resubmittal process shall continue in like manner until the submitted Work is approved.  In the event that any disapproval results from a cause other than failure of the submitting Party to fulfill any of its obligations under this Contract, the Guaranteed Substantial Completion Date and other relevant milestones shall automatically be extended as provided at Section 5.1 above.

35

(i) that Kiewit, particularly on large or fast-track projects, may not make final selection of some Subcontractors until later in the project, and (ii) that Kiewit has the right to select Subcontractors as long as such selection would not result in failure by Kiewit to satisfy the requirements of this Contract.  The subcontracting of any portion of the Work, as described in Exhibit A, shall not relieve Kiewit of responsibility for performance of the Work as provided therein.  Subject to the foregoing, Kiewit shall have the right to subcontract such portions of the Work (but not all of the Work) as it shall determine to be necessary to others which, in turn, shall have the right to subcontract such portions of the Work assigned to them, if any, as they shall deem necessary.

3.3Geotechnical Analysis and Foundation Basis

The Scope of Work is based upon Exhibit D, Site Geotechnical Report dated April 20, 2007 (the Geotechnical Report”). To supplement this preliminary analysis, the following comments are noted.

·The corn silos will likely be on piles

·Other areas of the plant are expected to be supported on native soil, geopiers, or to over excavate and re-compact.

Kiewit’s design also assumes no bedrock, or groundwater, other than as set forth in the Geotechnical Report, will be encountered, and deep foundations i.e. piles, geopiers, etc. will be used for the corn silo loads.  Other areas of the plant will use over-excavated/re-compacted or native soil.  The design assumes that all soils can be excavated with small scrapers and used for fill.  The design does not provide for the handling or disposal of unsuitable soils, buried refuse or debris.  The design assumes that design soil compaction can be achieved using the existing site soils.  All subsurface conditions shall be considered to be consistent with native soils with no below grade obstructions.

A final geotechnical report shall be provided by the Owner, coordinated with Kiewit..  It shall include borings, samples and laboratory testing sufficient to determine the existing soil conditions for design and construction of the foundations and other specific features for all major equipment items including tanks, cooling tower, stacks, buildings, plant components, disposal facilities, and roads.  The report shall include recommendations for foundations, site surfacing/fill materials, and roadway fill.

1.2Coordination

1.2.1KIEWIT shall coordinate the PERFORMANCE TEST with OWNER during the *** PERFORMANCE TEST period.  This coordination of the PERFORMANCE TEST activities will be handled by a KIEWIT Representative designated to serve as KIEWIT’s Test Coordinator (“Test Coordinator”).  The Test Coordinator will work with an individual designated by the OWNER to be its Representative for the PERFORMANCE TEST to set the test schedule and to coordinate operations during the test period. KIEWIT will also assign KIEWIT Shift Coordinators to support the operation during the test period.

1.2.2OWNER shall supply, or cause to be supplied, all feedstock, utilities and other supplies and services required to conduct the PERFORMANCE TEST, as specified under Section 1.1.1 above, throughout the entire Plant during all PERFORMANCE TESTS.

1.2.3OWNER shall direct its personnel in the operation of the Plant in a manner consistent with the operating parameters provided in the Operations Manual.  Owner’s personnel shall be under the direction of Kiewit.

1.3Conducting the Test

1.3.1The KIEWIT Test Coordinator shall be provided with operating data by the OWNER sufficient to verify that the Plant is operating at a condition suitable for initiation of the PERFORMANCE TEST.  At the scheduled start time of the PERFORMANCE TEST, the KIEWIT Test Coordinator will signal that the test has formally begun and will direct operators to take the initial test measurements. The test will be conducted over a *** period of operation.  During the Test period, the Plant shall be operated by the OWNER in compliance with the KIEWIT Operations Manual and instructions provided by KIEWIT, including, without limitation, adjustments in temperatures, pressures, feedstock rates, steam flow, and other process control inputs, provided these adjustments do not result in unsafe operating conditions.  Plant operators will monitor and record operating data according to standard procedures and in addition will record the supplemental data specified in this protocol on data sheets in the form to be provided by KIEWIT.  Records will be developed from permanent Plant equipment that is calibrated immediately prior to test.  All test measurements will be reviewed by the Test Coordinator (or a designated Representative) and OWNER.  If the Test Coordinator or the Owner Representative believes that there might be a problem with the measurement method or reading, the reading will be retaken and verified by the Test Coordinator and OWNER’S Representative. Immediately upon the conclusion of the PERFORMANCE TEST, the Test Coordinator will meet with Representatives of OWNER to review the test results.  KIEWIT and OWNER shall each be given a copy of the test results.  If the Performance Guarantees have been met, then OWNER shall promptly issue a notice to KIEWIT to such effect.  If the PERFORMANCE TESTS have not been met, then OWNER shall issue a written notice to KIEWIT within *** of completion of the PERFORMANCE TESTS indicating in what manner such Performance Guarantees have not been successfully completed.

1.3.2If the *** test period is interrupted for any reason within KIEWIT’s control or OWNER’S control, a *** test period will resume after the cause for the interruption has been corrected and the Plant has achieved an acceptable operating capacity at substantially the same rate immediately prior to the interruption.  KIEWIT and OWNER shall stop the PERFORMANCE TEST if it becomes obvious that it cannot be carried to a

2

satisfactory conclusion in the current attempt.  If the PERFORMANCE TEST has been interrupted for reasons not attributable to KIEWIT, and continues to be interrupted such that KIEWIT has spent a cumulative period of *** on site since the commencement of the test, then OWNER shall compensate KIEWIT for the personnel that KIEWIT has on site.  This compensation period shall begin on the *** on site, and will continue until the completion of the PERFORMANCE TEST.  This compensation will cease should the inability to complete the PERFORMANCE TEST be the fault of KIEWIT.  Compensation rates shall be at Kiewit’s standard rates.

2.Analytical/Calculation Protocols

2.1Undenatured Fuel Ethanol Quality
	METHOD:	Analyze samples according to ASTM D4806-06. The last test result before emptying day tank into main storage tank shall determine the quality for the batch.

Obtain high heat value specification for gas from the utility providing natural gas to the site over the test period and calculate the BTU over the test period. Divide this value by the amount of undenatured ethanol produced during the test period to determine BTU per gallon of undenatured ethanol produced during the test period. Average results of all calculations for test period to determine natural gas consumption value for Performance Test.
	TEST POINT:	Plant gas meter
	FREQUENCY:	Once per ***
	PREPARATION:	Certify gas meter is properly calibrated and suspend all non-process use of natural gas. The gas meter shall be pressure and temperature compensated in accordance with the local gas company standards.

INTRODUCTION

This report summarizes the findings of the geotechnical investigation conducted for the Aventine Aurora West Ethanol Plant, which is located approximately two miles west of Aurora, Nebraska. The proposed ethanol plant will be located southeast of the intersection of U.S. Highway 34 and ‘N’ Road. The proposed location of the plant layout is provided in Appendix A.

The purpose of this exploration was to evaluate the subsurface conditions and provide recommendations regarding the geotechnical design of foundations and other geotechnical aspects of the proposed construction at the new ethanol plant site. We have completed the following scope of services for this project:

·Performed a site reconnaissance and reviewed geologic subsurface conditions

·Drilled 29 soil test borings to depths ranging from 20 to 80 feet

·Performed laboratory tests on soil samples obtained during the subsurface exploration

·Conducted a geotechnical engineering evaluation using information obtained from our observations, borings and laboratory test results and information available regarding the proposed construction

·Utilized information from several supplemental Geotechnical Investigations that were conducted as part of the other proposed construction operations at the site.

·Preparation of this geotechnical engineering report including our subsurface exploration results, laboratory test results, engineering evaluations, and geotechnical design and construction recommendations

The scope of this exploration did not include any environmental assessment for the presence of wetlands and/or hazardous or toxic materials in the soil or ground water on or near this site. Any statements in this report regarding odors, discoloration, or suspicious conditions are strictly for the information of our client.

This report was prepared by an engineer intern and was reviewed by a professional engineer registered in the State of Nebraska with the firm of Olsson Associates (OA). The conclusions and recommendations contained herein are based on generally accepted, professional, geotechnical engineering practices at the time of this report, within this geographic area. No other warranty is expressed or implied. This report has been prepared for the exclusive use of Aventine Renewable Energy Inc. with specific application to the proposed project.

PROJECT INFORMATION

Site Location and Description

This report presents the results of the geotechnical evaluation performed for the proposed Ethanol Plant site located between County Road ‘N’ and County Road ‘O’ along Highway 34, which is approximately 2 miles west of Aurora, Nebraska. The approximate location of the proposed ethanol plant is shown on the Site Location Plan, included in Appendix A.

At the time of our field exploration, the site was undeveloped with the majority of the site consisting of irrigated farmland. It should be noted that alfalfa was planted at the time of the field exploration. The ground surface was relatively flat and sloped gradually to the south and east. The existing site grades generally slope downward to the east and south with existing ground elevations ranging from a high of about 1813.0 feet in the western area of the site to a low of about 1802.0 feet in the southeast portion of the site.

In addition to the agricultural land, a railroad line running east and west is located along the southern boundary of the project site. An existing farmstead was also noted in the northeast area of the project site.

Project Description

The purpose of the proposed ethanol plant is to provide additional ethanol service to an existing ethanol plant which is located directly to the east of the proposed site. In order to provide access to the ethanol plant, a rail loop and overpass is currently under construction. Loading for the proposed structures at the ethanol plant are based on the structural information provided by Mark Rigdon with Bibb and Associates. A table titled Tank and Vessel Weights for the approximate structural loading conditions and proposed support types for the ethanol plant are presented in Appendix E. The proposed buildings will be slab-on-grade structures with an anticipated finished floor elevation near 1810.0 feet.

The proposed plant will initially be constructed to produce 100 million gallons per year (mgpy) with the capability to be expanded to an ultimate capacity of 220 mgpy. The ethanol plant will consist of grain storage silos and DDG storage silos, various process tanks, fermentation tanks, pre-engineered and engineered buildings, storage tanks, cooling tower, DDGS storage buildings and various equipment pads. The majority of the larger tanks across the site will be supported on an intermediate or deep foundation system with the majority of the buildings being supported on a shallow foundation system. Note that several of the structures are anticipated to be supported on a standard mat foundation system.

2

At the time of this report no information was available regarding the grain storage silos or DDG storage silos. It was assumed based on previous experience that the grain storage silos will require an allowable bearing capacity of at least 8,000 psf. Based on the foundation support requirements, the grain storage silos will likely need to be supported on a deep foundation system.

Based on the anticipated finished floor elevation of 1810.0 feet for the structures and the ground surface elevations obtained at the boring locations by our survey team, maximum excavation depths of approximately 3 feet and maximum fill depth of about 3 feet are anticipated in the plant area. Concrete and/or asphalt paved access and frontage roads will be located across the site along with new rail lines looping around the perimeter of the proposed plant. In regards to the finished floor elevation of 1810.0, the majority of the structures and buildings will be at or near this elevation with exception to the receiving pit, which is typically bearing at a depth of approximately 12 feet below the finished floor elevation of 1810.0.

A new bridge over the rail line is planned at the plant entrance. The proposed overpass will enter from the plant from the west and will be designed as a one-span structure, approximately 95 feet long. The approach abutments and embankments will be constructed using mechanically stabilized earth (MSE) walls. The approach embankments will have a maximum height of 30 feet, at the abutments. A previous geotechnical investigation has already been completed to address the foundation design for the bridge and MSE walls.

A rail line loop is also being installed around the perimeter of the proposed plant area. Earthen embankments will be constructed to maintain the required grade for the rail line. Based on the site plan it is anticipated that the top of rail (TOR) elevation will range from 1807.0 to 1814.0, which will require varying fill and excavation depths along the alignment.

Note: At the time of this report, six storm water detention ponds were planned across the proposed construction site with varying base elevations.

As stated previously, please note that the recommendations for the overpass, MSE walls and rail loop were provided in the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006.

EXPLORATORY AND TEST PROCEDURES

Field Exploration

The field exploration program for the final investigation at the ethanol site consisted of performing 29 soil test borings at the locations depicted on the Boring Location Plan (Appendix A). The borings were staked and the ground surface elevations determined in the field by an OA survey crew. Note that in addition to the soil test borings and laboratory data for the final report, review was made of several supplemental reports that were conducted as part of the varying construction operations for the proposed ethanol plant. Please reference the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006 for the additional information.

The soil test borings were advanced to depths ranging from 20 to 80 feet with a truck-mounted drill rig using 4-inch diameter continuous-flight augers. Soil samples were obtained at selected intervals in the test borings. Soil samples designated as “U” samples on the boring logs (Appendix B) were obtained in general accordance with ASTM D-1587 (Thin-Walled Tube Sampling of Soils). Soil samples designated as “SS” samples were obtained in general accordance with ASTM D-1586 (Penetration Test and Split-Barrel Sampling of Soils). Recovered samples were sealed in steel tubes and transported to a laboratory where they were extruded, sealed in plastic containers, labeled and stored for future laboratory testing.

Descriptions of the soils encountered in the soil test borings were prepared in general accordance with ASTM D-2488 (Visual-Manual Procedure for Description and Identification of Soils). Soil stratification, as shown on the Boring Logs, represents soil conditions at the boring locations; however, variations may occur between or around the boring locations. The lines of demarcation represent the approximate boundary between soil types, but the transition may be more gradual. Water level readings were obtained in the drill holes at the times and under conditions stated on the Boring Logs.

Laboratory Testing

Descriptions of the soils encountered in the soil test borings were prepared in general accordance with ASTM D-2488 (Visual-Manual Procedure for Description and Identification of Soils). Soil stratification, as shown on the Boring Logs, represents soil conditions at the boring locations; however, variations may occur between or around the boring locations. The lines of demarcation represent the approximate boundary between soil types, but the transition may be more gradual.

4

Laboratory tests were performed to evaluate the engineering properties of the recovered soil samples. Unconfined compression tests were used to define the stress-strain characteristics and related shear strength of the cohesive soils. Consolidation tests were performed on thin-walled tube samples of foundation material to evaluate consolidation characteristics under an in-situ and saturated condition. Atterberg Limits tests were conducted to aid in the classification of the soils under the Unified Soils Classification System and to evaluate the shrink/swell characteristics of the soils.

All tests were conducted in general accordance with current American Society of Testing and Materials (ASTM) or other appropriate test procedures. A summary of the laboratory test results is presented in Appendix C.

SUBSURFACE CONDITIONS

Test Boring Summary

The following soil types were encountered in the soil test borings performed at the site.

Developed Zone

Every soil test boring encountered a varying thickness of developed zone (approximately 6 to 12 inches in depth), which consisted of varying amounts of organics and roots. Organic material is typically considered unsuitable for structural support or for use as structural fill due to its high organic content. For budgeting purposes, a 10-inch depth is recommended for topsoil removal.

Peoria Loess

Peoria loess was encountered beneath the developed zone (See Appendix B Boring Logs for locations and depths regarding where the lean clay was encountered). Soils identified as Peoria loess generally were light brown to dark brown, dry to very moist, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 11.2 to 30.1 percent, dry densities ranging from 81.9 to 110.5 pounds per cubic foot (pcf) and unconfined compressive strengths ranging from 0.5 to 1.8 tons per square foot (tsf). Atterberg limit tests performed on the Peoria loess soils indicated liquid limits ranging from 35 to 40 and plastic indexes ranging from 14 to 20. The unconfined compressive strength values indicate a soft to stiff consistency for the cohesive Peoria loess soils.

Sangamon Formation

The Sangamon Formation was encountered beneath the Peoria loess (See Appendix B Boring Logs for locations and depths regarding where the lean clay was encountered). Soils identified as part of the Sangamon Formation generally were dark brown to dark reddish brown, moist to very moist, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 24.7 to 29.9 percent, dry densities ranging from 85.0 to 95.9 pcf and unconfined compressive strengths ranging from 0.8 to 1.0 tsf. The unconfined compressive strength values indicate a firm to stiff consistency for the cohesive Sangamon soils.

6

Loveland Formation

The Loveland formation was encountered beneath the Sangamon Formation at varying depths across the site (See Appendix B Boring Logs for location and depths regarding where the lean clay was encountered). Soils identified as the Loveland formation generally were reddish brown to brown, moist to very, lean clay. Laboratory tests on recovered soil samples from this stratum depicted moisture contents ranging from 15.3 to 27.2 percent, dry densities ranging from 91.2 to 112.9 pcf and unconfined compressive strengths ranging from 0.7 to 3.3 tsf. Atterberg limit tests performed on the Loveland formation indicated liquid limits ranging from 29 to 40 and plastic indexes ranging from 13 to 24. The unconfined compressive strength values indicate a firm to very stiff consistency for the cohesive Loveland formation soils.

Alluvium

The alluvium was encountered at varying depths across the site (See Appendix B Boring Logs for location and depths regarding where the poorly graded to clayey sand was encountered). Soils identified as alluvium generally were light brown, moist to wet, clayey sand to poorly graded sand. The blow counts for the poorly graded alluvium typically ranged from 10 to 67 blows per foot (bpf) indicating a relative density ranging from medium dense to very dense. In addition to the poorly graded sands, lean clay was also noted in soil test borings B-20 and B-23.

After completion of the drilling operations, ground water was not encountered in any of the soil test borings. We note that groundwater levels will fluctuate depending on seasonal variations of precipitation and other factors such as temporary perched conditions near the retention ponds that were not evident or present at the time of drilling. Ultimately, these conditions may result in a groundwater condition that is at a higher elevation at some time in the future. The Drainage and Groundwater Consideration section of this report will address any site drainage concerns.

Note: The previously reported laboratory test data is based solely on the soil test borings that were conducted for this investigation. Review should be made to the Preliminary Report of Geotechnical Exploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006 and the Report of Geotechnical Exploration for the Aurora Coop Expansion, dated August 28, 2006 for more information on the laboratory test data.

CONCLUSIONS AND RECOMMENDATIONS

The conclusions and recommendations presented in the following sections of this report are based on the information available regarding the proposed construction, the results obtained from our soil test borings and laboratory tests, and our experience with similar projects. Because the samples obtained from the soil test borings represent a very small statistical sampling of subsurface conditions, it is possible that conditions will be encountered during construction that are substantially different from those indicated by the soil test borings. In these instances, adjustments to design and construction may be necessary.

The recommendations presented in this report are based on the Site Plan and project information provided by Aventine Renewable Energy, Inc, Bibb and Associates and the assumptions stated in this report. Changes in the proposed location or design of the structures can have significant effects on the conclusions and recommendations of the geotechnical report. OA should be contacted in the event of such changes to re-evaluate our recommendations.

Site Preparation – Non-Building Areas

Site preparation should begin by removing all vegetation, trees, topsoil, roots, and other deleterious materials. A minimum stripping depth of 10 inches will be required to remove the developed zone material. The stripping depth should be adjusted as necessary in the field to remove all topsoil. The stripped material shall be removed from the proposed construction areas. The topsoil strippings are suitable fill material for covering the last 6 to 9 inches of earthen berms and excavation slopes along with filling in any landscape areas.

In the farm stead area, any required tree removal should also be completed at this time. Care should be taken to thoroughly remove all root systems from the proposed construction areas. Materials disturbed during removal of stumps should be undercut and replaced with structural fill. A zone of desiccated soils may exist in the vicinity of the trees. The desiccated soils have a higher swell potential and should also be undercut and replaced with structural fill. Deeper organic soils may be encountered within more heavily tree-covered areas, which should also be undercut and stockpiled with the topsoil materials.

Site clearing, grubbing, and stripping will need to be performed only during dry weather conditions. Operation of heavy equipment on the site during wet conditions could result in excessive rutting and mixing of organic debris with the underlying soils.

8

Proofrolling operations are recommended in the non-building areas since future expansion is possible. Any areas to receive structural fill in future building or tank areas should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling should also be performed in areas requiring mass excavation after the rough finished subgrade elevation has been achieved. Proofrolling operations should be observed on a full-time basis by a qualified inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The areas that may require undercutting and/or stabilization should be identified at the time of construction, and the stabilization method recommended will depend on the location and depth of the soft area.

Fill placed in the non-building areas should be compacted in accordance with the recommendations stated in the Structural Fill section of the report.

Note: In addition to the tree removal at the existing farm stead in the northwest area of the project site, it will also be critical that all existing building foundations and any grain bin foundation areas be excavated and replaced with structural fill in accordance with the structural fill section of this report. Care should be given to insure that all rubble and concrete associated with demolition operations be removed in its entirety from the project site.

Site Preparation -Buildings and Tank Areas

In all new fill and excavation areas, vegetation, topsoil, roots, and other deleterious materials (typically 10 inches in depth), deemed unsuitable by the engineer’s field representative shall be removed from the proposed construction areas, and replaced with controlled fill. The topsoil strippings are suitable fill material for covering the last 6 to 9 inches of earthen berms and excavation slopes along with filling in landscape areas. Note that due to the varying crops that have been planted over the years it will be critical that the engineer’s field representative be present to insure all topsoil is properly removed. Areas of extensive root development (especially from alfalfa vegetation) may require additional core-out operations to insure an adequate subgrade is achieved prior to placement of any structural fill.

9

Any required tree removal should also be completed at this time. Care should be taken to thoroughly remove all root systems from the proposed construction areas. Materials disturbed during removal of stumps should be undercut and replaced with structural fill. A zone of desiccated soils may exist in the vicinity of the trees. The desiccated soils have a higher swell potential and should also be undercut and replaced with structural fill. Deeper organic soils may be encountered within more heavily tree-covered areas, which should also be undercut and stockpiled with the topsoil materials.

Site clearing, grubbing, and stripping will need to be performed only during dry weather conditions. Operation of heavy equipment on the site during wet conditions could result in excessive rutting and mixing of organic debris with the underlying soils.

The areas to receive structural fill in the building and tank areas should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling should also be performed in areas requiring mass excavation after rough finished subgrade elevation has been achieved. Proofrolling operations should be observed by a full-time inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The identification of areas that may require undercutting and/or stabilization should be based on the actual conditions at the time of construction, and will depend on the location of the soft area.

NOTE: Information obtained during the field exploration and laboratory testing indicated that there are areas of weak material present across the site. Therefore, it will be critical that proofrolling operations occur across the entire area of the proposed site in order to identify these areas that are near the existing ground surface. Failure to identify and remediate these areas, could result in excessive movement of structures once construction is completed.

Foundation Design

Based on the foundation loading requirements for the proposed structures and stipulated soil bearing capacity conditions, Table 1 is provided to define the acceptable bearing capacity, type of foundation system required and the estimated settlements associated with the various loading conditions. Based on the allowable bearing capacity that is utilized, Table 1 references the recommended foundation system that is at or just below the allowable settlement tolerances.

Note 1) Lack of foundation information does not allow for estimation of settlement. Assumed structure will be supported on an equipment mat.

Note 2) * - No applied load was provided. Reported bearing indicates an allowable bearing capacity.

Note 3) ** - Indicates applied bearing load was calculated from footing dimensions and structure loads

11

Please note that the settlement values listed in Table 1 were calculated based on two conditions. The first condition, listed under the “existing” column, analyzed the soils beneath the foundation elements under the assumption that in-situ soil would remain at the current moisture contents and saturation percentages. The second condition, listed under the “saturated” column, analyzed the soils beneath the foundation elements under the assumption that they became saturated. Overall, the risk of moisture increases and additional consolidation settlement is dependent on the surface drainage conditions and proximity of the structures as they relate to the retention pond locations. These assumptions and well as the degree of conservatism was taken into account when determining the recommended foundation system.

DDGS Storage Building

Based on information from Bibb and Associates and experience with similar structures, it is anticipated that the DDGS Storage Building will be supported on a shallow foundation to carry the building load and a mat foundation/concrete floor slab to carry the live load within the building. Loading conditions, provided by Bibb and Associates indicated a dead load of 2,000 psf for the building structure and an assumed live load of 1,500 psf, would be sufficient for the interior portion of the building where the concrete floor slab is supporting the grain.

Based on the site plan provided by Aventine, it was assumed that the total dimension of the DDGS storage building will be approximately 120 by 600 feet. Loading conditions indicate that the DDGS Storage Building can tolerate 1-inch total and ½-inch differential movement. Due to the deep influence zone induced by the mat foundation/concrete floor slab and the anticipated live load of 1,500 psf, remedial measures are recommended to properly support the proposed structure.

Note: The information contained within the section of the report is based on the assumption that there will be no column loads within the interior portion of the DDGS Storage building. If this assumption is found to be inaccurate, OA should be contacted to reevaluate this section of the report.

Settlement data was utilized to determine the anticipated settlement for the proposed DDGS Storage Building under two conditions. The first condition, analyzed the foundation under a saturated condition, assuming that all of the subgrade would become saturated at some point. The second condition analyzed the foundation under an “in-situ” condition, which assumed that the existing subgrade would remain at its current moisture content and saturation percentage. Based on those assumptions, the anticipated settlement for the first and second conditions resulted in settlement that ranged from 2 to 3 inches and 1 to 2 inches, respectively. Based on previous experience with structures of this size, tolerable ranges of settlement are approximately 2-inch total and 1-inch differential were used as the controlling criteria in our analysis.

12

Based on an assumed finished floor elevation of 1810.0, the placement of approximately 3 to 5 feet of structural fill will be required to reach the floor subgrade elevation. In addition to the structural fill placement within the building footprint and at least 10 feet beyond the perimeter of the DDGS Storage Building a surcharge to an elevation of 1818.0 is required. The intent of the proposed surcharge is to induce consolidation of the underlying soft compressive layers of soil prior to construction operations. The area of surcharge is shown on the Surcharge/Settlement Plate Map (Included in Appendix F).

Based on construction sequence regarding grading operations with respect to foundation installation, it is recommended that mass grading and associated surcharge operations be completed at least 45 to 60 days in advance of foundation/footing construction. The duration of the surcharge or time rate to achieve 90 percent consolidation assumed a double drainage condition. It is recommended that settlement monitoring be implemented to determine when settlement is complete. Two settlement-monitoring plates with locations identified on the Surcharge/Settlement Plate Map (included in Appendix F) are recommended in the areas of the DDGS Storage building. The two settlement plates will verify when primary consolidation is complete while providing the necessary documentation required to determine when foundation excavation operations can begin. The settlement plates should be installed at the present ground surface. During the consolidation process, the elevation of the settlement monuments should be monitored at least twice a week and surveyed to the nearest l00th of a foot. Note that a surcharge load was applied to the Dry Fertilizer Plant as part of the Coop Expansion which resulted in approximately 1.5 inches of settlement in a period of 50 days. Based on the site conditions for the proposed plant, a similar time frame should be expected for the DDGS Storage Building.

All structural fill should be compacted in accordance to the recommendations stated in the Structural Fill section of this report. In regards to the surcharge material placed above the finished floor elevation, it is recommended the material be compacted to at least 90 percent of the proctor value. No moisture range is specified for the surcharge material since it will be removed after the settlement is complete. Because the area of the DDGS Storage building will require structural fill to achieve the finished floor elevation of 1810.0, it is an option after the structural fill is placed to utilize the strippings of the developed zone from across the site as the surcharge material placed above the finish floor elevation. It should be noted, that the developed zone is only suitable for areas of surcharge and care should be used to ensure all of the developed zone strippings are removed from the building area after completion of the surcharge.

13

Upon completion of construction of the DDGS Storage Building, it will be critical that absolutely no moisture may be allowed to enter or weep into the area below the concrete floor slab. To prevent moisture from entering between the areas within the perimeter wall footings it is recommended that caulking be placed in any cold joints and the area beyond the building must have sufficient drainage away from the foundation system.

The site should be graded at a minimum of a 20H:1V slope away from the proposed building, and this should extend a minimum of 40 foot beyond the perimeter of the building. If a slope of 20H:1V is not attainable, concrete pavement should be used to prevent water from entering the subgrade soils around the structure. All cracks and voids in the paving areas must be sealed with caulk to prevent water from infiltrating into the underlying subgrade. As an extra precaution, a high density polyethylene (HDPE) membrane could be attached to the perimeter of the foundation wall to promote drainage away from the foundation systems and minimize the risk of surface runoff from infiltrating into the soil subgrade below the bearing surface of the grain silos, which could ultimately induce additional settlement. If utilized, the HPDE membrane should extend a minimum horizontal distance at least 10 feet out from the ring wall footing.

Note: It is critical these site drainage recommendations be implemented to prevent excessive  settlement.

Shallow Foundations

Based on the results of the subsurface exploration, laboratory test results, and our engineering evaluation, the subsurface conditions at this site are suitable for supporting the proposed structures as identified in Table 1 on a shallow foundation system. The appropriate foundation system should be selected based on tolerable settlement limits for the respective structure. At the proposed finished floor elevations near 1080.0 feet (USGS datum), the exterior and interior shallow foundation system will be supported in the natural clay soils or structural fill, depending on location.

Based on the laboratory test results and the drilling exploration, we recommend that the footings for the structures be designed for the allowable bearing capacities shown in Table 1. The net allowable bearing pressure refers to the bearing pressure at foundation level in excess of the surrounding overburden pressure. The recommended soil bearing capacity includes a factor of safety of at least 3 against shear failure. Footings should have minimum dimensions in accordance with local building codes. Exterior footings and footings in unheated areas should bear at a minimum depth

14

of 3.5 feet below the lowest adjacent final ground surface. It is recommended that any interior footings in heated areas bear at a depth as shallow as possible below the lowest adjacent final ground surface. The analysis for interior and exterior footings utilized a bearing depth of 2 and 3.5 feet, respectively, below the finished floor elevation.

Based on the soil properties estimated for this site, and assuming the recommended bearing capacity from Table 1 for the shallow foundation systems are utilized, any consolidation of the underlying soil is anticipated to be within the tolerable ranges. Provided the recommendations contained in this report are followed, total post-construction settlements are anticipated to be in the ranges as shown in Table 1. To reduce effects of differential settlement and lateral load forces, a floating floor slab, independent from the wall and column loads, with expansion joints will be critical in minimizing the potential cracking that can occur along and around the proposed foundation system. Floor slab control joints should be used to reduce damage due to shrinkage cracks.

It is possible that some soils at the site will have an allowable soil bearing pressure less than the recommended design value. Therefore, foundation bearing surface evaluations should be performed by an OA representative during footing construction to aid in the identification of such soils. After the evaluations and any required remedial measures are performed, concrete should be placed as quickly as possible to avoid exposure of the foundation subsoils to wetting, drying or freezing. If soils in the areas of the foundation support are subjected to such conditions, the footing excavations should be reevaluated.

Intermediate Foundation System

Based on the existing site conditions, required bearing capacities and risk of unacceptable settlement, it is our recommendation that the heavier loaded structures referenced in Table 2 can also be supported on an intermediate foundation system.

In order to achieve total and differential settlement values and to obtain required bearing capacities, we recommend utilizing an intermediate foundation system that can be provided by Geopier© or vibro stone columns. In our opinion, due to the deep influence zones of the large mat and tank foundations; core-out or surcharge load operations would not be feasible due to the extreme depth of excavation or height of surcharge that would be required to reduce the settlements to within acceptable limits. In addition, these types of remedial measures also cause time delays on the order of 60 to 90 days which can often slow down the construction activity on site.

15

The intermediate foundation system would require certain structures be supported on a Geopier© or vibro stone column system. Either foundation system would extend through the compressible zones of material that exist beneath the footprint of the proposed structures and bear into the stiffer material below.

Upon completion of the structural foundation plans, The Geopier Foundation Company, Hayward Baker and Subsurface Constructors, Inc. should be contacted to provide feasibility, design and cost information for the use of either Geopiers© or vibro stone columns, respectively. The following table provides the location, point of contact and respective phone numbers.

TABLE 2
INTERMEDIATE FOUNDATION SYSTEM CONTACTS

Company	Contact	Phone Number	Email Address
Geopier Foundation Company	Bob Lapke	(402) 597-6000	blapke@geopiermw.com
Hayward Baker	Frank Swekosky	(630) 339-4308	FJSwekosky@HaywardBaker.com
Subsurface Constructors	W. Lyle Simonton	(314) 421-2460	lsimonton@subsurfaceconstructors.com

The intermediate systems should include the total cost associated with mobilization, installation of Geopier© or vibro stone columns including concerns related to ground water and soil stabilization of the drilled shaft, and removal of any spoil piles. Based on the most economical cost that meets the previously stated criteria, it is recommended that Aventine Renewable Energy, Inc. enter into an agreement with one of the three companies, so a cost to stabilize the soil can be completed immediately upon completion of the grading operations. Bibb & Associates should be able to provide each firm with the structural drawings that requires the foundation system to be supported on an intermediate system. The intermediate foundation company should also provide recommendations regarding how the shallow footing system is to be supported and/or connected to the intermediate foundation system. OA can provide any input needed to assist in development of those recommendations as well as help coordinate the bidding and award process between the three companies so Aventine Renewable Energy, Inc. receives the most economical bid price.

16

The Geopier© or vibro stone column option will also result in reduced installation time for a given footing location, compared to the time required for installation associated with augered-in-place piles. A vibro stone column or Geopier© system allows for the installation of the concrete footing immediately after the column of crushed aggregate is placed.

Deep Foundation System

Based on the existing site conditions and required foundation bearing capacities, it is our recommendation the grain elevators and grain storage silos be supported on a deep foundation system.

In order to achieve total and differential settlement values and to obtain required bearing capacities, we recommend utilizing an auger cast-in-place foundation system. In our opinion, due to the deep influence zones of the large mat and tank foundations; core-out operations would not be feasible due to the extreme depth of excavation that would be required to reduce the settlements to within acceptable limits.

We recommend the final design utilize auger cast-in-place piles to support the associated mat foundations and tanks. The auger cast-in-place piles should be based on the following:

I.Piles consisting of augered cast-in-place concrete piles utilizing the individual allowable compressive capacities shown in Table 3. A tension capacity equal to three tenths the compressive capacity should be assumed in final design. Minimum center-to-center pile spacing should be no less than 3 pile diameters. No reduction in individual pile capacity for group action is needed for this spacing. The structural capacity of the piles should be determined using applicable AASHTO codes.

II.It is our recommendation the augered, cast-in-place piles bear into the medium dense to dense poorly graded sand. Table 3 indicates the proposed bearing depth of the augered, cast-in-place pile.

17

TABLE 3

DEEP FOUNDATION AUGERED CAST-IN-PLACE PILES

Auger-cast Pile Diameter (inches)	Designed Pile Length (ft)	Minimum Tip Elevation (ft)	Allowable Compressive Capacity (tons)
14	65	1738.0	70
14	70	1733.0	75
16	60	1743.0	77
16	65	1738.0	100
18	60	1743.0	90
18	65	1738.0	120

·Specification requirements that are needed for augered, cast-in-place, concrete piles include design of the grout mix to limit bleeding of completed piles and contractor responsibility for increased length of piles or additional piles to compensate for soil disturbance if it is necessary to withdraw the auger without grouting. The grout mix at a minimum should be required to achieve a 28-day compressive strength of 4,000 psi. The contractor should be assigned responsibility for any effects pile installation has on previously installed piles, and to lengthen the disturbed pile as directed by the geotechnical engineer. It is advisable to prohibit installation of piles less than 6 pile diameters apart, on the same day, to reduce the risk of disturbance to piles containing uncured grout. To check the suitability of the bearing stratum during pile installation, a full-time OA representative should verify that the base depth is no higher than the elevations stated in Table 3 and that each cast-in-place pile is drilled into the medium dense to dense poorly graded sand. The addition of water to aid in drilling should not be allowed. Should the piles be required to resist uplift loads the structural engineer will be required to determine the reinforcement depth through consultation with the geotechnical engineer. In accordance with ACI 318-10.9.1 reinforcing consisting of about 1 percent of the pile cross sectional area to a depth of 10 to 15 feet is common for the augered piles to accommodate incidental bending moments and transient lateral loads. Ultimately the structural engineer should determine the reinforcement required and overall depth based on the design condition parameters.

18

IV.Specifications should require the contractor to provide a grout head pump that will maintain six to eight feet of grout head pressure. It is recommended the specification state that the  auger be extracted at a regular rate of no greater than 2 to 3 feet per second, and the entire cast-in-place pile be placed in a single continuous pour. No construction joints are to be allowed within the pile. It should be noted that the recommended extraction rate is based off of a pump capacity of 1 cubic foot per stroke, and the extraction rate should be adjusted based on the capacity of the grout pump.

V.A previously performed load test was completed for the Coop Expansion and field verified the bearing capacity and associated settlement is within the design parameters, therefore we do feel it is necessary to perform a pile load test of the auger cast pile.

VI.In regards to the connection of the grain bins and silos to the perimeter footing of the ring wall foundations, we recommend utilizing flashing, or some other type of preventative  measure, to ensure that rainwater doesn’t seep or drain into the area between the base of  the tank and concrete mat.

VII.Based on the existing soil conditions encountered in the clays, silts and sands, a lateral modulus of subgrade reaction value of 150 kips per cubic foot is recommended.

VIII.Upon completion of the deep foundation system for each structure and the placement of the structural fill, total post- construction settlements are anticipated to be 1 inch or less with  minimal, if any, differential settlements.

Please note that while this section of the report is specific to the grain silos and DDG silos, the above recommendations are also applicable to the various tanks and structures that were recommended to utilize an intermediate or deep foundation system in Table 1. In the event that it was found to be more cost effective to utilize a deep foundation system rather than a vibro-stone column or Geopier© system, the above recommendations should be utilized for foundation design.

Floor Slab Subgrade Preparation

The soil subgrade in the areas of concrete slab-on-grade support is often disturbed during foundation and superstructure construction. Additionally, floor slab areas are often disturbed by construction equipment traffic between the time of initial grading and final construction. To prepare the floor slab subgrade, the top 12 inches of the subgrade in the building areas below the floor slab

19

should be compacted to a minimum of 98 percent of the maximum dry density as determined by ASTM D698-91, Standard Proctor Moisture-Density Relationship. The moisture content should also be controlled between -1 and +3 percent of the optimum. The final subgrade should be proofrolled and evaluated by a full-time inspector immediately prior to placement of the concrete to detect any localized areas of instability. If unstable soils are encountered which cannot be adequately densified in place, such soils will typically require the installation of additional crushed stone materials or a geosynthetic over the soft soils.

Regarding the potential for expansive clays, numerous Atterberg limit tests were performed on the soils at the site. Per the graphical plots of the liquid limit and plasticity indexes, expansive soils were encountered at various locations. However, the depth in which they were encountered was well below the anticipated floor elevation and will not influence construction operations. Therefore, no additional remedial measures are deemed necessary to achieve the required criteria of less than 3¤4 inches of potential vertical rise of an exposed concrete floor slab in the building.

Based on the fact that groundwater was not encountered at the time of final drilling operations, the placement of a synthetic barrier to minimize potential vapor rise through the slab is not necessary. Assuming these recommendations are implemented, a subgrade modulus of at least 150 psi/in for the floor slab design is acceptable.

Structural Fill

During construction, we recommend that fill materials placed in the building areas have a liquid limit of less than 50 and a plasticity index less than 30. Whenever possible, highly plastic silt (MH) or fat clay (CH) soils should not be placed within the upper 3 feet of the final ground elevation. Soils in this zone, which have a liquid limit greater than 50 and a plasticity index greater than 30 will typically require removal or blending with less plastic materials to result in lower Atterberg limits.

In addition to the plasticity characteristics, the fill soils should also be relatively free of organic materials (less than about two hundredths of a percent by weight) and other deleterious material. In addition, the soils should not contain particle sizes larger than three inches.

Based on the results of our laboratory testing program, a majority of the on site materials meet the previously mentioned structural fill criteria. During grading operations, representative samples of the proposed structural fill materials should be periodically checked via laboratory testing to verify

20

compliance with structural fill requirements. A representative from the testing agency should be on site on a full-time basis to monitor excavation and grading operation as well as the suitability of fill materials. Any imported fill material should be tested prior to placement at the site to verify it complies with the criteria stated in this section of the report.

Suitable fill material should be placed in thin lifts (lift thickness depends on type of compaction equipment, but in general, lifts of 8 inches loose measurement is recommended). The soil should be compacted by heavy compaction equipment such as a Caterpillar 815 sheepsfoot roller. Within small excavations, such as in utility trenches (less than 24 inches in width), around manholes or behind retaining walls, we recommend the use of “wacker packers”, “Rammax” compactors or vibrating plate compactors to achieve the specified compaction. Loose lift thickness of 4 inches are recommended in small area fills. Structural fill and backfill must be compacted in accordance with the criteria stated in Table 4.

TABLE 4

STRUCTURAL FILL PLACEMENT GUIDELINES

Areas of Fill Placement	Compaction Recommendation (ASTM D698Standard Proctor)	Moisture Content (Percent of Optimum)
If Granular Cushion is utilized Beneath Floor Slab	98%*	As necessary to obtain density
Floor Slab/Soil Subgrade Material – 1’-0” below the base of the floor slab	98%	-1 to +3 percent
Structural fill placed within 10 feet beyond the perimeter of the building pad	98%	-1 to +3 percent
Pavement Aggregate Base – 0’-8” below base of pavement	98%*	As necessary to obtain density
Pavement Soil Subgrade Material – 0’-8” below the base of the Pavement Aggregate Base	98%	-1 to +3 percent
Pavement Soil Subbase - At depths greater than 0’-8” below the base of the Pavement Aggregate Base	95%	-3 to +3 percent
Structural fill placed within the embankment of the railroad lines	98%	-1 to +3 percent
Utility Trenches – Within building and pavement areas	98%	-1 to +3 percent
Storm Detention Pond and Non-structural Fill Areas	95%	-1 to +3 percent
Beneath Landscaped/Grass Areas	92%	As necessary to obtain density

·Alternative Compaction Method – 60% Relative Density

21

The moisture content of suitable borrow soils should generally be between the specified ranges in Table 4. More stringent moisture limits may be necessary with certain soils. Based on the moisture content of the soil samples at the time of drilling operations, adjustments to the moisture content will be necessary to allow compaction in accordance with project specifications. Dependent on the percentage of fines, the clean free-draining aggregates utilized in the granular cushion beneath the floor slab could alternatively be consolidated by means of a vibratory compactor to at least 60% “relative density”, as determined in accordance with ASTM D 4253 (Standard Test Methods for Maximum lndex Density and Unit Weight of Soils Using a Vibratory Table) and D 4254 (Standard Test Methods for Minimum lndex Density and Unit Weight of Soils and Calculations of Relative Density).

Seismic Site Classification

Based on the subsurface conditions encountered in the borings, we recommend using a Seismic Site Class Definition of “D” per IBC 2003. There is no significant risk of liquefaction or mass movement of the on-site soils due to a seismic event.

Pavement Subgrade Preparation

Based on construction activities that have occurred, prior to this report, the upper two to three feet of expansive “hard-pan” Peoria loess has been removed and replaced with imported lean clay for the perimeter loop roadway. In addition the roadways within the plant will have the subgrade properly reworked in the final 8 inches below the aggregate base. Therefore, the final pavement subgrade implemented within the plant just prior to the placement of the concrete pavement should consist of 8 inches of the soil subgrade compacted to at least 98% of ASTM D-698, Standard Proctor, at a moisture content of -1 to +3 percent of optimum. After the subgrade soil is prepared, the area should be proofrolled with a loaded dump truck, scraper, or similar rubber-tired equipment weighing at least 25 tons. Proofrolling operations should be observed by a full-time inspector. Unstable and unsuitable soils, which are revealed by proofrolling and which cannot be adequately densified in-place, should be removed under the direction of the full-time inspector. It may be necessary to perform selective removal of soft, wet soils and/or stabilize existing soft soils in-place. If required, the methods of stabilization will typically include a lift of crushed stone materials or a geosynthetic over the soft soils. The identification of areas that may require undercutting and/or stabilization should be based on the actual conditions at the time of construction, and will depend on the location of the soft area.

22

Once the subgrade soil has been visually observed to be stable, we recommend the placement of an 8-inch crushed limestone base course for the Heavy-Duty Pavement. The crushed limestone aggregate should meet the following gradation, which has 80 to 100 percent passing the 1-inch sieve, 50 to 95 percent passing the  ¾-inch sieve, 24 to 55 percent passing the 0.375-inch sieve, 11 to 37 percent passing the No. 4 sieve, 7 to 26 percent passing the No. 10 sieve, and 0 to 6 percent passing the No. 200 sieve. A recycled crushed concrete (NDOR Standard Specifications, Table 1033.11) is also deemed acceptable as an aggregate base. With a design life of 20 years and the seasonal changes in Nebraska, the pavement subgrade meeting the compaction specification at the time of installation has the potential to rapidly deteriorate without the use of an 8-inch crushed limestone base course or recycled crushed concrete. In regards to any future parking lot areas, it is recommended that a 4-inch crushed limestone base or recycled crushed concrete be utilized.

Since the coefficient of drainage is a critical factor in determining the pavement design thickness, it is also recommended that lateral drainage lines be installed along the edge of the roadway pavement for Heavy-Duty Pavement. The drainage lines should properly daylight into drainage ways and/or collector systems. Seasonal weather conditions along with surface runoff saturating the aggregate subbase can have a significant impact on the design life of the pavement. At a minimum, the drainage lines should be located on each side of the roadway edge and flow at least 4 inches below the aggregate subbase. If a storm sewer collection system is anticipated, the edge drains should gravity drain to the randomly located inlets and properly discharge any subsurface water that is collected in the drainage lines. Assuming a drainage system is implemented to eliminate any subsurface water, a good drainage coefficient value of 1.15 was utilized in the pavement design software.

It is important that the subgrade support be relatively uniform, with no abrupt changes in the degree of support. Non-uniform pavement support can result from the transition at cut and fill areas, varying soil moisture contents, varying soil types, and where utility backfill has been placed in areas to be paved. Improper subgrade preparation such as inadequate vegetation removal, proofrolling, and compaction can also result in non-uniform subgrade support.

Pavement Design

Pavement design is influenced by the anticipated traffic loads and volumes for the Aurora West Ethanol Plant, site subgrade conditions, pavement materials, and the desired design life. The recommended pavement thickness is based on our experiences with the alternate pavement types and equivalent pavement sections based on recognized structural coefficients.

23

The recommended design requires that the site be properly prepared in accordance with the Pavement Subgrade Preparation section of this report and that site drainage be provided to minimize the future wetting of the pavement subgrade. A pavement design life of 20 years was used. AASHTO pavement design procedures were used to estimate the required pavement thickness. The following parameters were adopted for the thickness design:

·Equivalent Single Axle Load:	14,000,000 ESAL’s for Access/Frontage Roads
·Equivalent Single Axle Load:	3,000,000 ESAL’s for Intermediate/Haul Roads
·Equivalent Single Axle Load:	200,000 ESAL’s for associated parking lot
·Stabilized Subbase:	8” cohesive lean clay or silt, compacted to at least 98% of ASTM D-698, Standard Proctor, at a moisture content between –1 and +3 percent of optimum
·Stabilized Subbase:	8” crushed limestone/recycled crushed concrete for Intermediate/Haul Roads and Access/Frontage Roads 4” crushed limestone/recycled crushed concrete for parking lot
·CBR value:	3.0
·Working stress (PCC)	600 psi

The Standard-Duty and Heavy-Duty pavement recommendations are based on a design life of 20 years, terminal serviceability = 2.25, reliability = 90%, initial serviceability = 4.2, and standard deviation = 0.35 for rigid pavements. In regards to the load transfer value, the Standard-Duty pavement assumed the saw joints were not doweled but for the Heavy-Duty pavement analysis the analysis utilized doweled joints to achieve the recommended pavement thickness.

Based on the above design parameters, we recommend the following minimum pavement design thickness.

As stated previously, the Heavy-Duty Pavement in addition to the stabilized subbase of 8-inch crushed limestone or recycled crushed concrete should have dowel bars located at the transverse control joints to help eliminate the potential of joint failure. The implementation of dowels at the transverse joints will help transfer the loads and help decrease the necessary thickness of concrete.

Surface drainage around the pavement and proper maintenance are also important for long-term performance. Curbs should be backfilled as soon as possible after construction of the pavement. Backfill should be compacted and should be sloped to prevent water from ponding and infiltration under the pavement. All pavement joints should be caulked and any cracks should be quickly patched or sealed to prevent moisture from reaching and softening the subgrade.

Lateral Earth Pressures

The following soil parameters are provided for use in designing retaining walls, truck dock walls and/or foundation walls subject to lateral earth pressures. The parameters are based on the assumption that retained soils will be similar in composition to the onsite soils that were encountered in this investigation.

Retaining walls which are rigidly restrained at the top and are essentially unable to deflect or rotate should be designed for “at rest” earth pressure conditions. Retaining walls that are unrestrained at the top and are free to deflect or rotate slightly may be designed for “active” earth pressure conditions. The “passive” earth pressure condition should be used to evaluate the resistance of soil to lateral loads. Table 6 presents recommended values of earth pressure coefficients based on our experience with soils in the area. Equivalent fluid densities are frequently used for the calculation of lateral earth pressures for the “at-rest” and “active” conditions and are therefore provided in Table 6. These pressures do not apply to highly expansive clays with Liquid Limits above 50 and Plastic Indexes above 30 or expansive shales. Expansive shales can swell, producing very high lateral earth pressures.

The lateral earth pressure design recommendations are based on the following assumptions:

·For active earth pressure, wall must rotate about base, with top lateral movements 0.002 Z to 0.004 Z, where Z is wall height

·Drained conditions assume a permanent drainage system behind the retaining wall that will allow no development of hydrostatic pressure

·Horizontal backfill (i.e., no sloping backfill above the top of the wall)

·The upper 42 inches do not contribute resistance against horizontal movement if the soil is subject to frost action and seasonal volume change

·Onsite backfill soils having a bulk unit weight of 120 pcf

·Backfill soils placed within the height of the retaining wall consisting of selected lean clay should be tested to verify the lean clays exhibit low plasticity

·Imported granular backfill soils having an angle of internal friction of 32 degrees

·Uniform surcharge, where S is surcharge pressure, in pounds per square foot (psf)

·Heavy equipment and other concentrated load components not included

·No safety factor is included

The cohesive conditions assume the backfill soils placed within seven tenths the height of the retaining wall height consist of selected lean clay or silt exhibiting an Atterberg liquid limit of less than 50. Should the cohesive parameters from Table 6 be utilized, a granular fill of at least two feet behind the wall is still recommended for the drained condition. For granular values to be valid, the granular backfill must extend out from the base of the wall at an angle of 45 and 60 degrees from the active and passive cases, respectively. Utilizing a locally available aggregate meeting the gradation of 100 percent passing the 1-inch, 77 to 97 percent passing the No. 4 sieve, 50 to 70 percent passing the No. 10 sieve, 16 to 40 percent passing the No. 30 sieve and 0 to 3 percent passing the No. 200 sieve is considered acceptable.

To calculate the resistance to sliding, a frictional resistance of 500 psf is recommended for footings bearing on approved cohesive bearing soil. To calculate the resistance to sliding for footings bearing on a suitable crushed limestone, an ultimate coefficient of friction value of 0.5 is recommended. Should the footing bear on the soil subgrade, we recommend using an alternative coefficient of friction of 0.3. Should an aggregate base be utilized as foundation bearing soil, the aggregate should have a minimum friction angle of 32 degrees and assume no cohesion value. A factor of safety of at least 1.5 to 2 should be applied.

27

Slopes and Temporary Excavations

The owner and the contractor should make themselves aware of and become familiar with applicable local, state, and federal safety regulations, including current OSHA excavation and trench safety standards. Construction site safety generally is the sole responsibility of the contractor. The contractor shall also be solely responsible for the means, methods, techniques, sequences, and operations of construction operations. OA is providing the following information solely as a service to our client. Under no circumstances should OA’s provision of the following information be construed to mean that we are assuming responsibility for construction site safety or the contractor’s activities, such responsibility is not implied and should not be inferred.

The contractor should be aware that slope height, slope inclination, and excavation depths (including utility trench excavations) should in no case exceed those specified in local, state, or federal safety regulation; e.g., OSHA Health and Safety Standards for Excavations, 29 CFR Part 19266, or successor regulations. Such regulations are strictly enforced and, if not followed, the owner, the contractor, or earthwork or utility subcontractors could be liable for substantial penalties.

For this site, the overburden soil encountered in the upper 20 feet of our exploratory borings consisted of lean clays. We anticipate that OSHA will classify these materials as type B. OSHA recommends a maximum slope inclination of 1 H: 1V for type B soils.

Note: Soils encountered in the construction excavations may vary significantly across the site. Our soil classifications are based solely on the materials encountered in the widely spaced boring locations. The contractor should verify that similar conditions exist throughout the proposed area of excavation. If different subsurface conditions are encountered at the time of construction, OA must be contacted immediately to evaluate the conditions encountered. If any excavation, including a utility trench, is extended to a depth of more than 20 feet, OSHA requires that the side slopes of such excavation be designed by a professional engineer registered in the state where construction is occurring.

As an alternative to temporary slopes, vertical excavations can be temporarily shored. The contractor or the specialty subcontractor is responsible for the design of the temporary shoring in accordance with applicable regulatory requirements.

28

Construction Equipment Mobility

Some of the soils encountered at this site, may be highly susceptible to softening under the action of construction equipment traffic. Mitigation of equipment mobility problems and management of soft surficial soils will be greatly dependent on the severity of the problem, the season in which construction is performed and prevailing weather conditions.

To reduce equipment mobility problems and in order to deal with soft, wet, surficial soils the following recommendations are provided:

·Optimize surface water drainage at the site to maintain positive drainage away from work areas

·Whenever possible, wait for dry weather conditions to prevail, and do not operate construction equipment on the site during wet conditions. Rutting the surface will only aggravate the problem

·Use construction equipment that is well suited for the intended job under the site conditions. Heavy rubber-tired equipment typically requires better site conditions than light, track-mounted equipment

·Implement a construction schedule that realistically allows for rain days. Pressure to perform earthwork under a tight schedule is frequently counterproductive

Ultimately, it may be necessary to take steps to aggressively improve construction mobility if construction must proceed under unfavorable conditions. Methods for coping with equipment mobility problems may range from removing several feet of soft wet soils, to utilizing crushed stone materials and/or stabilization fabric. Other methods include cement modification of soils, lime stabilization, etc. The optimal approach should be evaluated by the geotechnical engineer at the time of construction.

Corrosivity and Thermal Resistivity of Soils

Note that these sections of the report were recently requested by Bibbs & Associates. Testing is currently underway and will be issued in the form of an addendum once the laboratory analysis is completed.

29

Drainage and Groundwater Considerations

After completion of the drilling operations, ground water was not encountered in any of the soil test borings. Therefore, it is not anticipated to be a concern during construction. We note that groundwater levels will fluctuate depending on seasonal variations of precipitation and other factors that were not evident at the time of drilling and may occur at higher elevations in proximity to the retention ponds at some time in the future.

Since moisture increases to the underlying soil can result in significant settlement, the site should also be graded to avoid water flows, concentrations, or standing water behind retaining walls, building foundations and tanks. If swales are designed at the top of the retaining walls, proper line and slope should be considered to avoid any water flow down behind retaining walls. Special attention to sources of storm water from building and tank roofs, gutter downspouts, and paved areas draining to one point is needed.

Additionally, in order to minimize concerns related to improper drainage away from building foundation that tends to soften when exposed to water, the following general recommendations are provided:

·Site grading should provide for efficient drainage of rainfall away from the tanks, mat foundations, buildings and pavement areas.

·Roof run-off should be collected and transferred directly to the storm sewer system, if possible, or to a location well away from the building and pavements. Conventional downspout drainage leading to splash blocks, though not as desirable, may be used.

·External hose connections should incorporate splash blocks to prevent localized accidental flooding of foundation soils. External hose connections should have cutoff valves inside the building to prevent accidental or unauthorized use of external hose connections.

·Building maintenance personnel should be informed of the potential problems associated with watering in close proximity to the building. Excessive watering of shrubs or lawns near buildings should be avoided. Placement of deep-rooted or water-intensive shrubs near buildings also should be avoided.

RE:	Aventine - Aurora West Ethanol Plant Addendum #1 – Chemical and Thermal Resistivity Testing
DATE:	May 15, 2007
PROJECT #:	2006-1563

The following sections of this addendum should be added to the Report of Geotechnical Exploration performed for the Aurora West Ethanol Plant dated April 20, 2007.

Corrosivity of Soils

A series of chemical tests were performed in accordance with AWWA C105/A21.5-05, Appendix A on representative samples of the subsurface soils. The results are presented in Table 1 below and are attached to this addendum.

TABLE 1
CHEMICAL TESTING RESULTS

Sample Boring	Sample  Depth (ft)	Resistivity (ohm/cm)	PH	Redox (mV)	Sulfides (mg/kg)
B-2	8.5-10.0	1261	6.7	282	NEG
B-3	3.5-5.0	4017	8.0	248	NEG
B-6	3.5-5.0	2018	7.4	247	NEG
B-12	1.0-2.5	4582	7.6	235	NEG
B-19	1.0-2.5	5897	7.7	237	NEG
B-22	3.5-5.0	6064	7.5	235	NEG
B-24	1.0-2.5	5275	5.8	268	NEG

Once compiled, the results of the chemical testing were evaluated on a point system utilizing the criteria presented in Table 2 to determine potentially corrosive conditions for underground utilities.

TABLE 2
SOIL TEST EVALUATION

Soil Characteristics Based on Samples Taken Down to Pipe Depth	Points*

0 to +50 mV	4
Negative	5
Sulfides:
Positive	3.5
Trace	2
Negative	0
Moisture:
Poor drainage, continuously wet	2
Fair drainage, generally moist	1
Good drainage, generally dry	0

* Ten points indicates that soil is corrosive to ductile-iron pipe; protection is needed.

† If sulfides are present and low or negative redox-potential results are obtained, add three points for this range.

Based on the test results of the chemical tests and point system presented in Table 2, the following point totals for each sample is provided in Table 3.

TABLE 3
CORROSIVITY POINT SYSTEM

Sample	Sample	Points
Boring	Depth (ft)	Resistivity	PH	Redox	Sulfides	Moisture	Total
B-2	8.5-10.0	10	0	0	0	2	12
B-3	3.5-5.0	0	0	0	0	2	2
B-6	3.5-5.0	5	0	0	0	2	7
B-12	1.0-2.5	0	0	0	0	2	2
B-19	1.0-2.5	0	0	0	0	2	2
B-22	3.5-5.0	0	0	0	0	2	2
B-24	1.0-2.5	0	0	0	0	2	2

The results of the tests indicate the point total varies from 2 to 12 across the site. Based on the AWWA guidelines, any point total greater than 10 requires corrosion protection. Therefore, it is recommended that any ductile iron pipe in the vicinity of soil test boring B-2 be double polyethylene encased. In addition, please note that the higher resistivity condition encountered in soil test boring B-2 was at a depth of 8.5 to 10 feet. Based on the overall results and proposed grading operations, it is also recommended that any utility lines located at depths greater than 5 feet below the existing borehole elevation be double encased.

A series of chemical tests according to AASHTO T-290 and AASHTO T-291 regarding sulfate and chloride content were also performed on representative samples of the subsurface soils. These tests were used to evaluate the soils for specific chemical factors that could be aggressive to concrete. The factors, in addition to the above pH and Redox values, include sulfate and chloride content. The results are defined as parts per million (ppm) and are provided in Table 4.

TABLE 4
CHEMICAL TESTS ON SOIL SAMPLES

Boring	Depth	Sulfates (ppm)		Chlorides (ppm)
No.	(ft)	Test Results	Required	Test Results	Required
B-2	8.5-10.0	12.1	Max. 200	4.1	Max. 100
B-3	3.5-5.0	15.5	Max. 200	4.2	Max. 100
B-6	3.5-5.0	21.1	Max. 200	5.5	Max. 100
B-12	1.0-2.5	20.1	Max. 200	4.0	Max. 100
B-19	1.0-2.5	15.4	Max. 200	3.9	Max. 100
B-22	3.5-5.0	19.1	Max. 200	4.7	Max. 100
B-24	1.0-2.5	17.7	Max. 200	5.2	Max. 100

Based on our experience and soil survey information, sulfate and chloride resistant cement will not be required for any

exposed concrete. Regarding the cement type based on the chemical test readings of sulfates and chlorides less than 200 ppm and 100 ppm, respectively, a Type I or Type II cement is considered acceptable. Maximum water/cement ratio by weight shall not exceed 0.5. Actual test results are included in the Appendix C, Laboratory Test Data.

Thermal Resistivity of Soils

A series of Thermal Resistivity testing was completed in accordance with ASTM D-5334 and IEEE 442. The results from the testing are presented in Table 5 below and are attached to this addendum.

TABLE 5
THERMAL RESISTIVITY TESTS ON SOIL SAMPLES

		Dry Density	Moisture	Thermal Resistivity (OC-cm/W)

B-20	Remolded	108.5	18.8	55	*	169	*
B-22	Remolded	102.2	14.8	78		234

* - Represents erroneous data due to sample contamination

Samples that were submitted for testing were tested under two conditions. The first condition required that the sample be remolded to resemble the in-situ soil conditions in each respective soil test boring. Upon obtaining the desired dry density and moisture content, the Thermal Resistivity was measured. The sample was then dried in an oven and tested again to determine the Thermal Resistivity of the material with no moisture.

It is important to note that the results from soil test boring B-20 are invalid and should be excluded from the data set. Laboratory notes indicate that the sample was primarily sand which is not representative of the upper 10 feet of the on-site material.

EXHIBIT E
MECHANICAL COMPLETION, COMMISSIONING, STARTUP

Definitions:

Mechanical Completion:  The completion of construction activities essential to the safe and proper operation of the Plant in accordance with the requirements of the Contract, as more fully listed below to the extent necessary to permit:

(i)safe and sound start-up and operation of the Plant as a fully integrated system; and

(ii)successful completion and conduct of the commissioning tests.

but excluding correction of minor non-operational matters such as painting, landscaping and nonessential insulation.  Nonessential insulation shall not include any insulation needed for personnel safety, any insulation that materially and negatively impacts the process or any outdoor process piping insulation required for freeze protection.

Irrespective of the following, Mechanical Completion shall be deemed to have occurred in the event feedstock has been introduced into the process and ethanol has been produced.

Commissioning:  The checking, testing and preparation of the Plant for operation, functional control loop checking, interlock testing, system purging and utility system startups, as more fully listed below.  In general, the tasks required for taking the Plant from Mechanical Completion and making it ready for start-up.

Ready for Startup:  When the activities listed for Mechanical Completion and Commissioning have occurred and the Plant is ready to mill corn at the hammer mills.  At that time, KIEWIT will notify OWNER that the Plant is Ready for Startup.  All paved roads must be completed before the Plant is ready for Startup.

Startup:  Startup begins with the initial feed of raw material to the Plant, filling of Equipment with operating material, startup and operation of individual process stages, adjustment and optimization of operating conditions, optimization of control loops, verification of startup, shutdown and partial load operations.  Utility system startups (unless integrated with the processing portions of the Plant) are a part of the Commissioning Phase.

Substantial Completion:  As defined below.

These events may not occur at the same point in time for all parts of the Plant.  Utility systems needed for operation of the rest of the Plant may reach Mechanical Completion, Commissioning and Startup before the main process parts of the Plant.  Some processing areas of the Plant or sub-systems of operating areas may reach Mechanical Completion and be Commissioned and Started up before other parts of the Plant, for example, grain receiving and storage may be completed and into operation, i.e., filled with grain, prior to other parts of the Plant.  Mechanical Completion, Commissioning and

1

PROCESS SAFETY MANAGEMENT
CONTRACTORS

A.Policy

Aventine Renewable Energy, Inc. is committed to the prevention of accidents and improving quality and productivity related to Contractor work by providing a safe workplace that protects Aventine and Contractor employees, the environment and the general public.

Aventine shall promote an attitude of partnership, cooperation, and communication with Contractors to enhance workplace safety. Personal safety is a fundamental responsibility of both Aventine and Contractor employees.

Aventine shall maintain the independent contractor status of its Contractors and their Subcontractors. Aventine shall not dictate the manner and means by which the Contractor performs its work, except where specified in the written contract; and, whenever unsafe acts/unsafe conditions pose an immediate threat to the safety or health of personnel; and/or potential damage to Aventine property.

B.Purpose

To establish a policy and procedure for providing Aventine employees with guidance in developing site-specific rules and practices to improve the safety and health performance of contractors who perform work at Aventine.

To ensure that all Contractor personnel are informed of the known potential fire, explosion, toxic release hazards, and other serious safety hazards related to their work or the process.

To ensure that all Contractor personnel are aware of all applicable Aventine safety rules and procedures pertaining to their work site, including the facility’s emergency procedures.

This procedure applies to Aventine employees responsible for Contractor selection, training, inspections and assessments, and for Contractor work involving new construction projects, major renovation, and repair/maintenance activities.

* Note: Repair/maintenance activities and incidental contractor work that do not compromise the safety of personnel, facilities, and processes are excluded. (E.g., janitorial and delivery services, etc.)

C.        Approach

Contract employees must perform their work safely. Considering that Contractors often perform very specialized and potentially hazardous tasks, such as confined space entry activities and non-routine repair activities; their work must be controlled while they are on or near a process covered by PSM. A permit system or work authorization system for these types of activities are required for all affected employees. The use of a work authorization system keeps an employer informed of contract employee activities. A well-run and well-maintained process, where employee safety is fully recognized benefits all of those who work in the facility whether they are employees of the employer or the contractor.

D.Responsibilities

When selecting a contractor, the employer must obtain and evaluate information regarding the contract employer’s safety performance and programs. The employer also must inform contract employers of the known potential fire, explosion, or toxic release hazards related to the contractor’s work and the process. The employers must explain to contract employers the applicable provisions of the emergency action plan; develop and implement safe work practices to control the presence, entrance, and exit of contract employers and contract employees in covered process areas; evaluate periodically the performance of contract employers in fulfilling their obligations; and maintain a contract employee injury and illness log related to the contractor’s work in the process areas.
