After reaching Substantial Completion, Kiewitagrees that Kiewit, at Kiewit’s sole cost and expense, shall take whateveraction is reasonably necessary and consistent with sound engineering practicesto cause the Plant to reach the Threshold; provided, Kiewit shall not, exceptas set forth in Section 16.1 below, be responsible for costs associated withany defects in Delta-T scope of work under Kiewit’s subcontract with Delta-Twhich result in failure to achieve the Threshold; Kiewit shall, however, beresponsible for any costs which are reimbursed to Kiewit by any manufacturer orsupplier associated with such defects.

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

Kiewit is obligated tocontinue all aspects of the Work necessary to achieve completion of PerformanceTests, Substantial Completion, the Threshold, and Final Acceptance (and inconnection therewith, Kiewit is obligated to expend all necessary

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

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

The sum of the countervailing factors,determined as set forth under Section 7.8 below, shall be deducted from the sumof the damages determined thereunder.  Inno case, however, shall Owner have any obligation to pay Kiewit as a result ofsuch calculation.  If the countervailingfactors are greater than the damages, the performance liquidated damages shallbe deemed to be zero.

3.3**                  **GeotechnicalAnalysis and Foundation Basis

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

·                  Thecorn silos will likely be on piles

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

Kiewit’sdesign also assumes no bedrock, or groundwater, other than as set forth in theGeotechnical 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 useover-excavated/re-compacted or native soil. The design assumes that all soils can be excavated with small scrapersand used for fill.  The design does notprovide for the handling or disposal of unsuitable soils, buried refuse ordebris.  The design assumes that designsoil compaction can be achieved using the existing site soils.  All subsurface conditions shall be consideredto be consistent with native soils with no below grade obstructions.

Afinal geotechnical report shall be provided by the Owner, coordinated withKiewit..  It shall include borings,samples and laboratory testing sufficient to determine the existing soilconditions for design and construction of the foundations and other specificfeatures for all major equipment items including tanks, cooling tower, stacks,buildings, plant components, disposal facilities, and roads.  The report shall include recommendations forfoundations, site surfacing/fill materials, and roadway fill.

Any differences between the finalgeotechnical report and the Geotechnical Report shall constitute a change(increase or decrease) to the allowances set forth in Exhibit P.

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

1.2.2        OWNER shallsupply, or cause to be supplied, all feedstock, utilities and other suppliesand services required to conduct the PERFORMANCE TEST, as specified underSection 1.1.1 above, throughout the entire Plant during all PERFORMANCE TESTS.

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

1.3           Conductingthe Test

1.3.1        The KIEWITTest Coordinator shall be provided with operating data by the OWNER sufficientto verify that the Plant is operating at a condition suitable for initiation ofthe PERFORMANCE TEST.  At the scheduledstart time of the PERFORMANCE TEST, the KIEWIT Test Coordinator will signalthat the test has formally begun and will direct operators to take the initialtest measurements. The test will be conducted over a *** period ofoperation.  During the Test period, thePlant shall be operated by the OWNER in compliance with the KIEWIT OperationsManual and instructions provided by KIEWIT, including, without limitation,adjustments in temperatures, pressures, feedstock rates, steam flow, and otherprocess control inputs, provided these adjustments do not result in unsafeoperating conditions.  Plant operatorswill monitor and record operating data according to standard procedures and in additionwill record the supplemental data specified in this protocol on data sheets inthe form to be provided by KIEWIT. Records will be developed from permanent Plant equipment that iscalibrated immediately prior to test. All test measurements will be reviewed by the Test Coordinator (or adesignated Representative) and OWNER.  Ifthe Test Coordinator or the Owner Representative believes that there might be aproblem with the measurement method or reading, the reading will be retaken andverified by the Test Coordinator and OWNER’S Representative. Immediately uponthe conclusion of the PERFORMANCE TEST, the Test Coordinator will meet withRepresentatives of OWNER to review the test results.  KIEWIT and OWNER shall each be given a copyof the test results.  If the PerformanceGuarantees have been met, then OWNER shall promptly issue a notice to KIEWIT tosuch effect.  If the PERFORMANCE TESTShave not been met, then OWNER shall issue a written notice to KIEWIT within ***of completion of the PERFORMANCE TESTS indicating in what manner suchPerformance Guarantees have not been successfully completed.

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

satisfactoryconclusion in the current attempt.  Ifthe PERFORMANCE TEST has been interrupted for reasons not attributable toKIEWIT, and continues to be interrupted such that KIEWIT has spent a cumulativeperiod of *** on site since the commencement of the test, then OWNER shallcompensate 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 theinability to complete the PERFORMANCE TEST be the fault of KIEWIT.  Compensation rates shall be at Kiewit’sstandard rates.

Measure the sample moisture and starch content.  Convert total undenatured ethanol volume from the Rate Test to weight at  60oF. Divide the calculated mass quantity of undenatured ethanol by the  calculated corn mass quantity of total starch fed over the time period to  determine yield. In addition, this weigh belt total should be cross checked  by totaling all corn receipts, subtracting all foreign material content, and  taking into account the current corn bin volumes.

**PROJECTINFORMATION**

**Site Location**and Description

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

At the time of our field exploration, the site wasundeveloped with the majority of the site consisting of irrigated farmland. Itshould 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 andeast. The existing site grades generally slope downward to the east and southwith existing ground elevations ranging from a high of about 1813.0 feet in thewestern area of the site to a low of about 1802.0 feet in the southeast portionof the site.

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

**ProjectDescription**

The purpose of the proposed ethanol plant is toprovide additional ethanol service to an existing ethanol plant which islocated directly to the east of the proposed site. In order to provide accessto the ethanol plant, a rail loop and overpass is currently under construction.Loading for the proposed structures at the ethanol plant are based on thestructural information provided by Mark Rigdon with Bibb and Associates. Atable titled *Tank and Vessel Weights*forthe approximate structural loading conditions and proposed support types forthe ethanol plant are presented in Appendix E. The proposed buildings will beslab-on-grade structures with an anticipated finished floor elevation near1810.0 feet.

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

At the time of this report no information wasavailable regarding the grain storage silos or DDG storage silos. It wasassumed based on previous experience that the grain storage silos will requirean allowable bearing capacity of at least 8,000 psf. Based on the foundationsupport requirements, the grain storage silos will likely need to be supportedon a deep foundation system.

Based on the anticipated finished floor elevation of1810.0 feet for the structures and the ground surface elevations obtained atthe boring locations by our survey team, maximum excavation depths ofapproximately 3 feet and maximum fill depth of about 3 feet are anticipated inthe plant area. Concrete and/or asphalt paved access and frontage roads will belocated across the site along with new rail lines looping around the perimeterof 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 elevationwith exception to the receiving pit, which is typically bearing at a depth ofapproximately 12 feet below the finished floor elevation of 1810.0.

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

A rail line loop is also being installed around theperimeter of the proposed plant area. Earthen embankments will be constructedto maintain the required grade for the rail line. Based on the site plan it isanticipated that the top of rail (TOR) elevation will range from 1807.0 to1814.0, which will require varying fill and excavation depths along thealignment.

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

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

**EXPLORATORY AND TESTPROCEDURES**

**Field Exploration**

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

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

Descriptions of the soils encountered in the soil testborings were prepared in general accordance with ASTM D-2488 (Visual-ManualProcedure for Description and Identification of Soils). Soil stratification, asshown on the Boring Logs, represents soil conditions at the boring locations;however, variations may occur between or around the boring locations. The linesof demarcation represent the approximate boundary between soil types, but thetransition may be more gradual. Water level readings were obtained in the drillholes at the times and under conditions stated on the Boring Logs.

Laboratory tests were performed to evaluate theengineering properties of the recovered soil samples. Unconfined compressiontests were used to define the stress-strain characteristics and related shearstrength of the cohesive soils. Consolidation tests were performed onthin-walled tube samples of foundation material to evaluate consolidationcharacteristics under an in-situ and saturated condition. Atterberg Limitstests were conducted to aid in the classification of the soils under theUnified Soils Classification System and to evaluate the shrink/swellcharacteristics of the soils.

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

**SUBSURFACE CONDITIONS**

**Test Boring Summary**

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

**Developed Zone**

Every soil test boring encountered a varying thicknessof developed zone (approximately 6 to 12 inches indepth), which consisted of varying amounts of organics and roots. Organicmaterial is typically considered unsuitable for structural support or for useas structural fill due to its high organic content. For budgeting purposes, a10-inch depth is recommended for topsoil removal.

**Peoria Loess**

Peoria loess was encountered beneath the developedzone (See Appendix B Boring Logs for locations and depths regarding where thelean clay was encountered). Soils identified as Peoria loess generally were light brown to darkbrown, dry to very moist, lean clay. Laboratory tests on recovered soil samplesfrom 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) andunconfined compressive strengths ranging from 0.5 to 1.8 tons per square foot(tsf). Atterberg limit tests performed on the Peoria loess soils indicatedliquid limits ranging from 35 to 40 and plastic indexes ranging from 14 to 20.The unconfined compressive strength values indicate a soft to stiff consistencyfor the cohesive Peoria loess soils.

**Sangamon Formation**

The Sangamon Formation was encountered beneath thePeoria loess (See Appendix BBoring Logs for locations anddepths regarding where the lean clay was encountered). Soils identified as partof the Sangamon Formation generally were dark brown to dark reddish brown,moist to very moist, lean clay. Laboratory tests on recovered soil samples fromthis stratum depicted moisture contents ranging from 24.7 to 29.9 percent, drydensities ranging from 85.0 to 95.9 pcf and unconfined compressive strengthsranging from 0.8 to 1.0 tsf. The unconfined compressive strength valuesindicate a firm to stiff consistency for the cohesive Sangamon soils.

**Loveland Formation**

The Loveland formation was encountered beneath theSangamon Formation at varying depths across the site (See Appendix B BoringLogs for location and depths regarding where the lean clay was encountered). Soils identified as theLoveland formation generally were reddish brown to brown, moist to very, leanclay. Laboratory tests on recovered soil samples from this stratum depictedmoisture contents ranging from 15.3 to 27.2 percent, dry densities ranging from91.2 to 112.9 pcf and unconfined compressive strengths ranging from 0.7 to 3.3tsf. Atterberg limit tests performed on the Loveland formation indicated liquidlimits ranging from 29 to 40 and plastic indexes ranging from 13 to 24. Theunconfined compressive strength values indicate a firm to very stiff consistencyfor the cohesive Loveland formation soils.

**Alluvium**

The alluvium was encountered at varying depths acrossthe site (See Appendix B Boring Logs for location and depths regarding wherethe poorly graded to clayey sand was encountered). Soils identified as alluviumgenerally 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 67blows per foot (bpf) indicating a relative density ranging from medium dense tovery dense. In addition to the poorly graded sands, lean clay was also noted insoil test borings B-20 and B-23.

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

**Note:**Thepreviously reported laboratory test data is based solely on the soil testborings that were conducted for thisinvestigation. Review should be made to the Preliminary Report of GeotechnicalExploration for the Proposed Ethanol Plant, Aurora, Nebraska, dated June 2006and the Report of Geotechnical Exploration for the Aurora Coop Expansion, datedAugust 28, 2006 for more information on the laboratory test data.

**CONCLUSIONS ANDRECOMMENDATIONS**

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

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

**Site Preparation**– Non-Building Areas

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

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

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

Proofrolling operations are recommended in thenon-building areas since future expansion is possible. Any areas to receivestructural fill in future building or tank areas should be proofrolled with aloaded dump truck, scraper, or similar rubber-tired equipment weighing at least25 tons. Proofrolling should also be performed in areas requiring massexcavation after the rough finished subgrade elevation has been achieved. Proofrollingoperations should be observed on a full-time basis by a qualified inspector.Unstable and unsuitable soils, which are revealed by proofrolling and whichcannot be adequately densified in-place, should be removed under the directionof the full-time inspector. It may be necessary to perform selective removal ofsoft, wet soils and/or stabilize existing soft soils in-place. If required, themethods of stabilization will typically include a lift of crushed stonematerials or a geosynthetic over the soft soils. The areas that may requireundercutting and/or stabilization should be identified at the time ofconstruction, and the stabilization method recommended will depend on thelocation and depth of the soft area.

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

**Note:**Inaddition to the tree removal at the existing farm stead in the northwest areaof the project site, it will also becritical that all existing building foundations and any grain bin foundationareas be excavated and replaced with structural fill in accordance with thestructural fill section of this report. Care should be given to insure that allrubble and concrete associated with demolition operations be removed in itsentirety 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 fromthe proposed construction areas, and replaced with controlled fill. The topsoilstrippings are suitable fill material for covering the last 6 to 9 inches of earthen berms andexcavation slopes along with filling in landscape areas. Note that due to thevarying crops that have been planted over the years it will be critical thatthe engineer’s field representative be present to insure all topsoil isproperly removed. Areas of extensive root development (especially from alfalfavegetation) may require additional core-out operations to insure an adequatesubgrade is achieved prior to placement of any structural fill.

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

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

The areas to receive structural fill in the buildingand tank areas should be proofrolled with a loaded dump truck, scraper, orsimilar rubber-tired equipment weighing at least 25 tons. Proofrolling shouldalso be performed in areas requiring mass excavation after rough finishedsubgrade elevation has been achieved. Proofrolling operations should beobserved by a full-time inspector. Unstable and unsuitable soils, which arerevealed by proofrolling and which cannot be adequately densified in-place,should be removed under the direction of the full-time inspector. It may benecessary to perform selective removal of soft, wet soils and/or stabilizeexisting soft soils in-place. If required, the methods of stabilization willtypically include a lift of crushed stone materials or a geosynthetic over thesoft soils. The identification of areas that may require undercutting and/orstabilization should be based on the actual conditions at the time ofconstruction, and will depend on the location of the soft area.

**NOTE**: Information obtained during thefield exploration and laboratory testing indicated that there are areas of weakmaterial present across the site. Therefore, it will be critical thatproofrolling operations occur across the entire area of the proposed site inorder to identify these areas that are near the existing ground surface.Failure to identify and remediate these areas, could result in excessivemovement of structures once construction is completed.

**Foundation Design**

Based on the foundation loading requirements for theproposed structures and stipulated soil bearing capacity conditions, Table 1 is provided to define the acceptablebearing capacity, type of foundation system required and the estimatedsettlements associated with the various loading conditions. Based on theallowable bearing capacity that is utilized, Table 1 references the recommended foundation system that is at orjust below the allowable settlement tolerances.

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

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

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

Please note that the settlement values listed in Table1 were calculated based on two conditions. The first condition, listed underthe “existing” column, analyzed the soils beneath the foundation elements underthe assumption that in-situ soil would remain at the current moisture contentsand saturation percentages. The second condition, listed under the “saturated”column, analyzed the soils beneath the foundation elements under the assumptionthat they became saturated. Overall, the risk of moisture increases andadditional consolidation settlement is dependent on the surface drainageconditions and proximity of the structures as they relate to the retention pondlocations. These assumptions and well as the degree of conservatism was takeninto account when determining the recommended foundation system.

**DDGSStorage Building**

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

Based on the site plan provided by Aventine, it wasassumed that the total dimension of the DDGS storage building will beapproximately 120 by 600 feet. Loading conditions indicate that the DDGSStorage Building can tolerate 1-inch total and 1⁄2-inch differential movement.Due to the deep influence zone induced by the mat foundation/concrete floorslab and the anticipated live load of 1,500 psf, remedial measures are recommended toproperly support the proposed structure.

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

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

Based on an assumed finished floor elevation of 1810.0, the placement of approximately3 to 5 feet of structural fill will be required to reach the floorsubgrade elevation. In addition to the structural fill placement within thebuilding footprint and at least 10 feetbeyond the perimeter of the DDGS Storage Building a surcharge to an elevationof 1818.0 is required. Theintent of the proposed surcharge is to induce consolidation of the underlyingsoft compressive layers of soil prior to construction operations. The area ofsurcharge is shown on the Surcharge/Settlement Plate Map (Included in AppendixF).

Based on construction sequence regarding gradingoperations with respect to foundation installation, it is recommended that massgrading and associated surcharge operations be completed at least 45 to 60 days in advance of foundation/footing construction. Theduration of the surcharge or time rate to achieve 90 percent consolidation assumed a double drainage condition. Itis recommended that settlement monitoring be implemented to determine whensettlement is complete. Two settlement-monitoring plates with locationsidentified on the Surcharge/Settlement Plate Map (included in Appendix F) are recommended in the areas of theDDGS Storage building. The two settlement plates will verify when primaryconsolidation is complete while providing the necessary documentation requiredto determine when foundation excavation operations can begin. The settlementplates should be installed at the present ground surface. During theconsolidation process, the elevation of the settlement monuments should bemonitored at least twice a week and surveyed to the nearest l00th of a foot. Note that a surcharge loadwas applied to the Dry Fertilizer Plant as part of the Coop Expansion whichresulted in approximately 1.5 inchesof settlement in a period of 50 days.Based on the site conditions for the proposed plant, a similar time frameshould be expected for the DDGS Storage Building.

All structural fill should be compacted in accordanceto the recommendations stated in the *StructuralFill*section of this report. In regards to the surcharge materialplaced above the finished floor elevation, it is recommended the material becompacted to at least 90 percentof the proctor value. No moisture range is specified for the surcharge materialsince it will be removed after the settlement is complete. Because the area of the DDGS Storage building willrequire structural fill to achieve the finished floor elevation of 1810.0, it is an option after thestructural fill is placed to utilize the strippings of the developed zone fromacross the site as the surcharge material placed above the finish floorelevation. It should be noted, that the developed zone is only suitable forareas of surcharge and care should be used to ensure all of the developed zonestrippings are removed from the building area after completion of thesurcharge.

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

The site should be graded at a minimum of a 20H:1Vslope away from the proposed building, and this should extend a minimum of 40foot beyond the perimeter of the building. If a slope of 20H:1V is notattainable, concrete pavement should be used to prevent water from entering thesubgrade soils around the structure. All cracks and voids in the paving areasmust be sealed with caulk to prevent water from infiltrating into theunderlying subgrade. As an extra precaution, a high density polyethylene (HDPE)membrane could be attached to the perimeter of the foundation wall to promotedrainage away from the foundation systems and minimize the risk of surfacerunoff from infiltrating into the soil subgrade below the bearing surface ofthe grain silos, which could ultimately induce additional settlement. Ifutilized, the HPDE membrane should extend a minimum horizontal distance atleast 10 feet out from the ring wall footing.

**Note:**It is critical these site drainagerecommendations be implemented to prevent excessive  settlement.

**ShallowFoundations**

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

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

14

----

of 3.5feet below the lowest adjacent final ground surface. It is recommendedthat any interior footings in heated areas bear at a depth as shallow as possiblebelow the lowest adjacent final ground surface. The analysis for interior andexterior footings utilized a bearing depth of 2 and 3.5 feet, respectively, below the finished floorelevation.

Based on the soil properties estimated for this site,and assuming the recommended bearing capacity from Table 1 for the shallow foundation systemsare utilized, any consolidation of the underlying soil is anticipated to bewithin the tolerable ranges. Provided the recommendations contained in thisreport are followed, total post-construction settlements are anticipated to bein the ranges as shown in Table 1. To reduce effects of differential settlementand lateral load forces, a floating floor slab, independent from the wall andcolumn loads, with expansion joints will be critical in minimizing thepotential cracking that can occur along and around the proposed foundationsystem. 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 anallowable soil bearing pressure less than the recommended design value.Therefore, foundation bearing surface evaluations should be performed by an ***OA***representativeduring footing construction to aid in the identification of such soils. Afterthe evaluations and any required remedial measures are performed, concreteshould be placed as quickly as possible to avoid exposure of the foundationsubsoils to wetting, drying or freezing. If soils in the areas of thefoundation support are subjected to such conditions, the footing excavationsshould be reevaluated.

**Intermediate Foundation**System

Based on the existing site conditions, requiredbearing capacities and risk of unacceptable settlement, it is ourrecommendation that the heavier loaded structures referenced in Table 2 can also be supported on anintermediate foundation system.

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

The intermediate foundation system would requirecertain structures be supported on a Geopier© orvibro stone column system. Either foundation system would extend through thecompressible zones of material that exist beneath the footprint of the proposedstructures 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 providefeasibility, design and cost information for the use of either Geopiers© or vibro stone columns, respectively. Thefollowing table provides the location, point of contact and respective phonenumbers.

The intermediate systems should include the total costassociated with mobilization, installation of Geopier© orvibro stone columns including concerns related to ground water and soilstabilization of the drilled shaft, and removal of any spoil piles. Based onthe most economical cost that meets the previously stated criteria, it isrecommended that Aventine Renewable Energy, Inc. enter into an agreement withone of the three companies, so a cost to stabilize the soil can be completedimmediately upon completion of the grading operations. Bibb & Associates should be able toprovide each firm with the structural drawings that requires the foundationsystem to be supported on an intermediate system. The intermediate foundationcompany should also provide recommendations regarding how the shallow footingsystem is to be supported and/or connected to the intermediate foundationsystem. ***OA***can provide any input needed to assist in development of those recommendationsas well as help coordinate the bidding and award process between the threecompanies so Aventine Renewable Energy, Inc. receives the most economical bidprice.

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

**Deep Foundation System**

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

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

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

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

II.                        Itis our recommendation the augered, cast-in-place piles bear into the mediumdense to dense poorly graded sand. Table 3 indicates the proposed bearing depthof the augered, cast-in-place pile.

·                             Specificationrequirements that are needed for augered, cast-in-place, concrete piles includedesign of the grout mix to limit bleeding of completed piles and contractorresponsibility for increased length of piles or additional piles to compensatefor 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 compressivestrength of 4,000 psi. The contractor should be assigned responsibility for anyeffects pile installation has on previously installed piles, and to lengthenthe disturbed pile as directed by the geotechnical engineer. It is advisable toprohibit installation of piles less than 6 pile diameters apart, on the sameday, to reduce the risk of disturbance to piles containing uncured grout. Tocheck the suitability of the bearing stratum during pile installation, afull-time ***OA***representativeshould verify that the base depth is no higher than the elevations stated inTable 3 and that each cast-in-place pile is drilled into the medium dense todense poorly graded sand. The addition of water to aid in drilling should notbe allowed. Should the piles be required to resist uplift loads the structuralengineer will be required to determine the reinforcement depth throughconsultation with the geotechnical engineer. In accordance with ACI 318-10.9.1reinforcing consisting of about 1 percent of the pile cross sectional area to adepth of 10 to 15 feet is commonfor the augered piles to accommodate incidental bending moments and transientlateral loads. Ultimately the structural engineer should determine thereinforcement required and overall depth based on the design conditionparameters.

IV.                    Specificationsshould require the contractor to provide a grout head pump that will maintainsix to eight feet of grout head pressure. It is recommended the specificationstate that the  auger be extracted at aregular rate of no greater than 2 to3 feet per second, and the entire cast-in-place pile be placed in a singlecontinuous pour. No construction joints are to be allowed within the pile. Itshould be noted that the recommended extraction rate is based off of a pumpcapacity of 1 cubic foot perstroke, and the extraction rate should be adjusted based on the capacity of thegrout pump.

V.                        Apreviously performed load test was completed for the Coop Expansion and fieldverified the bearing capacity and associated settlement is within the designparameters, therefore we do feel it is necessary to perform a pile load test ofthe auger cast pile.

VI.                    Inregards to the connection of the grain bins and silos to the perimeter footingof the ring wall foundations, we recommend utilizing flashing, or some othertype of preventative  measure, to ensurethat rainwater doesn’t seep or drain into the area between the base of  the tank and concrete mat.

VII.                Basedon the existing soil conditions encountered in the clays, silts and sands, alateral modulus of subgrade reaction value of 150 kips per cubic foot isrecommended.

VIII.            Upon completion of the deep foundationsystem 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 isspecific to the grain silos and DDG silos, the above recommendations are alsoapplicable to the various tanks and structures that were recommended to utilizean intermediate or deep foundation system in Table 1. In the event that it was found tobe more cost effective to utilize a deep foundation system rather than avibro-stone column or Geopier© system, the above recommendations should beutilized for foundation design.

**Floor Slab SubgradePreparation**

The soil subgrade in the areas of concreteslab-on-grade support is often disturbed during foundation and superstructureconstruction. Additionally, floor slab areas are often disturbed byconstruction equipment traffic between the time of initial grading and finalconstruction. To prepare the floor slab subgrade, the top 12 inches of thesubgrade in the building areas below the floor slab

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

Regarding the potential for expansive clays, numerousAtterberg limit tests were performed on the soils at the site. Per thegraphical plots of the liquid limit and plasticity indexes, expansive soilswere encountered at various locations. However, the depth in which they wereencountered was well below the anticipated floor elevation and will notinfluence construction operations. Therefore, no additional remedial measuresare deemed necessary to achieve the required criteria of less than 3¤4******inchesof potential vertical rise of an exposed concrete floor slab in the building.

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

**Structural**Fill

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

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

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

compliance with structural fill requirements. Arepresentative from the testing agency should be on site on a full-time basisto monitor excavation and grading operation as well as the suitability of fillmaterials. Any imported fill material should be tested prior to placement atthe site to verify it complies with the criteria stated in this section of thereport.

Suitable fill material should be placed in thin lifts(lift thickness depends on type of compaction equipment, but in general, liftsof 8 inches loose measurement is recommended). The soil should be compacted byheavy compaction equipment such as a Caterpillar 815 sheepsfoot roller. Within smallexcavations, such as in utility trenches (less than 24 inches in width), aroundmanholes 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 criteriastated in Table 4.

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

**Seismic SiteClassification**

Based on the subsurface conditions encountered in theborings, we recommend using a Seismic Site Class Definition of “D” per IBC2003. There is no significant risk of liquefaction or mass movement of theon-site soils due to a seismic event.

**Pavement SubgradePreparation**

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 theperimeter loop roadway. In addition the roadways within the plant will have thesubgrade properly reworked in the final 8 inches below the aggregate base.Therefore, the final pavement subgrade implemented within the plant just priorto the placement of the concrete pavement should consist of 8 inches of thesoil subgrade compacted to at least 98% of ASTM D-698, Standard Proctor, at a moisturecontent 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 similarrubber-tired equipment weighing at least 25 tons. Proofrolling operationsshould be observed by a full-time inspector. Unstable and unsuitable soils,which are revealed by proofrolling and which cannot be adequately densifiedin-place, should be removed under the direction of the full-time inspector. Itmay be necessary to perform selective removal of soft, wet soils and/orstabilize existing soft soils in-place. If required, the methods ofstabilization will typically include a lift of crushed stone materials or ageosynthetic over the soft soils. The identification of areas that may requireundercutting and/or stabilization should be based on the actual conditions atthe time of construction, and will depend on the location of the soft area.

22

----

Once the subgrade soil has been visually observed tobe stable, we recommend the placement of an 8-inch crushed limestone basecourse for the Heavy-Duty Pavement. The crushed limestone aggregate should meetthe following gradation, which has 80 to 100 percent passing the 1-inch sieve,50 to 95 percentpassing the  3⁄4-inch sieve, 24 to 55percent 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, Table1033.11) is also deemed acceptable as an aggregate base. With a design life of20 years and the seasonal changes in Nebraska, the pavement subgrade meetingthe compaction specification at the time of installation has the potential torapidly deteriorate without the use of an 8-inch crushed limestone base courseor recycled crushed concrete. In regards to any future parking lot areas, it isrecommended that a 4-inch crushed limestone base or recycled crushed concretebe utilized.

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

It is important that the subgrade support be relativelyuniform, with no abrupt changes in the degree of support. Non-uniform pavementsupport can result from the transition at cut and fill areas, varying soilmoisture contents, varying soil types, and where utility backfill has beenplaced in areas to be paved. Improper subgrade preparation such as inadequatevegetation removal, proofrolling, and compaction can also result in non-uniformsubgrade support.

**Pavement**Design

Pavement design is influenced by the anticipatedtraffic loads and volumes for the Aurora West Ethanol Plant, site subgradeconditions, pavement materials, and the desired design life. The recommendedpavement thickness is based on our experiences with the alternate pavementtypes and equivalent pavement sections based on recognized structuralcoefficients.

23

----

The recommended design requires that the site beproperly prepared in accordance with the *PavementSubgrade Preparation* section of this report and that site drainagebe provided to minimizethe future wetting of the pavement subgrade. A pavement design life of 20 years was used. AASHTO pavement design procedures were used to estimatethe required pavement thickness. The following parameters were adopted for thethickness design:

The Standard-Duty and Heavy-Duty pavementrecommendations 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, theStandard-Duty pavement assumed the saw joints were not doweled but for theHeavy-Duty pavement analysis the analysis utilized doweled joints to achievethe recommended pavement thickness.

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

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

Surface drainage around the pavement and propermaintenance are also important for long-term performance. Curbs should bebackfilled as soon as possible after construction of the pavement. Backfill should be compacted and should besloped to prevent water from ponding and infiltration under the pavement. Allpavement joints should be caulked and any cracks should be quickly patched orsealed to prevent moisture from reaching and softening the subgrade.

Theparameters are based on the assumption that retained soils will be similar incomposition to the onsite soils that were encountered in this investigation.

Retaining walls which arerigidly restrained at the top and are essentially unable to deflect or rotateshould be designed for “at rest” earth pressure conditions. Retaining wallsthat are unrestrained at the top and are free to deflect or rotate slightly maybe designed for “active” earth pressure conditions. The “passive” earthpressure condition should be used to evaluate the resistance of soil to lateralloads. Table 6 presents recommended values of earth pressure coefficients basedon our experience with soils in the area. Equivalent fluid densities arefrequently used for the calculation of lateral earth pressures for the “at-rest”and “active” conditions and are therefore provided in Table 6. These pressuresdo not apply to highly expansive clays with Liquid Limits above 50 and PlasticIndexes above 30 or expansive shales. Expansive shales can swell, producingvery high lateral earth pressures.

The lateral earth pressure design recommendations arebased on the following assumptions:

·                             Foractive earth pressure, wall must rotate about base, with top lateral movements0.002 Z to 0.004 Z, where Z is wall height

·                             Drainedconditions assume a permanent drainage system behind the retaining wall thatwill allow no development of hydrostatic pressure

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

·                             Theupper 42 inches do not contribute resistance against horizontal movement if thesoil is subject to frost action and seasonal volume change

·                             Onsitebackfill soils having a bulk unit weight of 120 pcf

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

·                             Importedgranular backfill soils having an angle of internal friction of 32 degrees

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

·                             Heavyequipment and other concentrated load components not included

·                             Nosafety factor is included

The cohesive conditions assume the backfill soilsplaced within seven tenths the height of the retaining wall height consist ofselected lean clay or silt exhibiting an Atterberg liquid limit of less than50. Should the cohesive parameters from Table 6 be utilized, a granular fill ofat least two feet behind the wall is still recommended for the drainedcondition. For granular values to be valid, the granular backfill must extendout from the base of the wall at an angle of 45 and 60 degrees from the activeand passive cases, respectively. Utilizing a locally available aggregatemeeting the gradation of 100 percent passing the 1-inch, 77 to 97 percent passing the No. 4sieve, 50 to 70 percent passing the No. 10 sieve, 16 to 40 percent passing theNo. 30 sieve and 0 to 3 percent passing the No. 200 sieve is consideredacceptable.

To calculate the resistance to sliding, a frictionalresistance of 500 psf is recommended for footings bearing on approved cohesivebearing soil. To calculate the resistance to sliding for footings bearing on asuitable crushed limestone, an ultimate coefficient of friction value of 0.5 isrecommended. Should the footing bear on the soil subgrade, we recommend usingan alternative coefficient of friction of 0.3. Should an aggregate base beutilized as foundation bearing soil, the aggregate should have a minimumfriction angle of 32 degrees and assume no cohesion value. A factor of safetyof at least 1.5 to 2 shouldbe applied.

**Slopes and TemporaryExcavations**

The owner and the contractor should make themselvesaware of and become familiar with applicable local, state, and federal safetyregulations, including current OSHA excavation and trench safety standards.Construction site safety generally is the sole responsibility of thecontractor. The contractor shall also be solely responsible for the means,methods, techniques, sequences, and operations of construction operations. ***OA***is providing thefollowing information solely as a service to our client. Under no circumstancesshould ***OA’s***provisionof the following information be construed to mean that we are assumingresponsibility 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 safetyregulation; e.g., *OSHA Health and SafetyStandards for Excavations,*29 *CFR****Part**19266*,or successor regulations. Such regulations are strictly enforced and, if notfollowed, the owner, the contractor, or earthwork or utility subcontractorscould be liable for substantial penalties.

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

***Note:***Soils encountered in the construction excavations mayvary significantly across the site. Our soil classifications are based solelyon the materials encountered in the widely spaced boring locations. Thecontractor should verify that similar conditions exist throughout the proposedarea of excavation. If different subsurface conditions are encountered at thetime of construction, **OA******must be contacted immediately to evaluate theconditions encountered. If any excavation, including a utility trench, isextended to a depth of more than 20 feet, OSHA requires that the side slopes ofsuch excavation be designed by a professional engineer registered in the statewhere construction is occurring.

As an alternative to temporary slopes, verticalexcavations can be temporarily shored. The contractor or the specialtysubcontractor is responsible for the design of the temporary shoring inaccordance with applicable regulatory requirements.

**Construction EquipmentMobility**

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

To reduce equipment mobility problems and in order todeal with soft, wet, surficial soils the following recommendations areprovided:

·                             Optimizesurface water drainage at the site to maintain positive drainage away from workareas

·                             Wheneverpossible, wait for dry weather conditions to prevail, and do not operateconstruction equipment on the site during wet conditions. Rutting the surfacewill only aggravate the problem

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

·                             Implementa construction schedule that realistically allows for rain days. Pressure toperform earthwork under a tight schedule is frequently counterproductive

Ultimately, it may be necessary to take steps toaggressively improve construction mobility if construction must proceed underunfavorable conditions. Methods for coping with equipment mobility problems mayrange from removing several feet of soft wet soils, to utilizing crushed stonematerials and/or stabilization fabric. Other methods include cementmodification of soils, lime stabilization, etc. The optimal approach should beevaluated by the geotechnical engineer at the time of construction.

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

**Drainage andGroundwater Considerations**

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

Since moisture increases to the underlying soil canresult in significant settlement, the site should also be graded to avoid waterflows, concentrations, or standing water behind retaining walls, buildingfoundations and tanks. If swales are designed at the top of the retainingwalls, proper line and slope should be considered to avoid any water flow downbehind retaining walls. Special attention to sources of storm water frombuilding and tank roofs, gutter downspouts, and paved areas draining to onepoint is needed.

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

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

·                             Roofrun-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 asdesirable, may be used.

·                             Externalhose connections should incorporate splash blocks to prevent localizedaccidental flooding of foundation soils. External hose connections should havecutoff valves inside the building to prevent accidental or unauthorized use ofexternal hose connections.

·                             Buildingmaintenance personnel should be informed of the potential problems associatedwith watering in close proximity to the building. Excessive watering of shrubs orlawns near buildings should be avoided. Placement of deep-rooted orwater-intensive shrubs near buildings also should be avoided.

***DRILLINGPROCEDURES***

Soil sampling and standard penetration testingperformed in accordance with ASTM D 1586. The standard penetration resistance (SPT) “N” value is the number of blows of a140 pound hammer falling 30 inches to drive a 2 inch O.D., 1.4 inch I.D.split-spoon sampler one foot. The thin-walled tube sampling procedure isdescribed by ASTM specification D 1587.

***WATERLEVEL MEASUREMENTS***

Water levels indicated on the boring logs are levelsmeasured in the borings at the times indicated. In relatively high permeablematerials, the indicated levels may reflect the location of groundwater. In lowpermeability soils, the accurate determination of groundwater levels is notpossible with only short-term observations.

The results of the tests indicate the point totalvaries from 2 to 12 across the site. Based on the AWWA guidelines, any point total greater than 10 requires corrosionprotection. Therefore, it is recommendedthat any ductile iron pipe in the vicinity of soil test boring B-2 be double polyethylene encased. In addition, please notethat the higher resistivity condition encountered in soil test boringB-2 was at a depth of 8.5 to 10 feet. Based on the overall results and proposedgrading operations, it is also recommendedthat any utility lines located at depths greater than 5 feet below the existingborehole elevation be double encased.

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

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

exposed concrete. Regarding the cementtype based on the chemical test readingsof sulfates and chlorides less than 200 ppm and 100 ppm, respectively, a Type Ior Type II cement is consideredacceptable. Maximum water/cement ratio by weight shall not exceed 0.5. Actual test results are included in the AppendixC, Laboratory Test Data.

* - Represents erroneous data due to sample contamination

Samples that were submitted for testing were testedunder two conditions. The first condition required that the sample be remoldedto resemble the in-situ soil conditions in each respective soil test boring. Upon obtaining the desired drydensity and moisture content, the Thermal Resistivity was measured. Thesample was then dried in an oven and tested again to determine the Thermal Resistivity of the material with nomoisture.

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

**EXHIBIT EMECHANICAL COMPLETION, COMMISSIONING, STARTUP**

**Definitions:**

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

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

(ii)                                  successful completion and conduct of thecommissioning tests.

but excluding correction of minornon-operational matters such as painting, landscaping and nonessentialinsulation.  Nonessential insulationshall not include any insulation needed for personnel safety, any insulationthat materially and negatively impacts the process or any outdoor processpiping insulation required for freeze protection.

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

Commissioning:  Thechecking, testing and preparation of the Plant for operation, functionalcontrol loop checking, interlock testing, system purging and utility systemstartups, as more fully listed below.  Ingeneral, the tasks required for taking the Plant from Mechanical Completion andmaking it ready for start-up.

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

Startup:  Startupbegins with the initial feed of raw material to the Plant, filling of Equipmentwith operating material, startup and operation of individual process stages, adjustmentand optimization of operating conditions, optimization of control loops,verification of startup, shutdown and partial load operations.  Utility system startups (unless integratedwith the processing portions of the Plant) are a part of the CommissioningPhase.

Substantial Completion:  As defined below.

These events may not occur at the same point intime for all parts of the Plant.  Utilitysystems needed for operation of the rest of the Plant may reach MechanicalCompletion, Commissioning and Startup before the main process parts of thePlant.  Some processing areas of thePlant or sub-systems of operating areas may reach Mechanical Completion and beCommissioned and Started up before other parts of the Plant, for example, grainreceiving and storage may be completed and into operation, i.e., filled withgrain, prior to other parts of the Plant. Mechanical Completion, Commissioning and

**C.        Approach**

Contract employees must perform their work safely.Considering that Contractors often perform very specialized and potentially hazardous tasks, such as confined spaceentry activities and non-routine repair activities; their work must be controlledwhile they are on or near a process coveredby PSM. A permit system or work authorization system for these types ofactivities are required for allaffected employees.

The employers must explain to contractemployers the applicable provisions of the emergency action plan; develop andimplement safe work practices to control the presence, entrance, and exit ofcontract employers and contract employees in covered process areas; evaluateperiodically the performance of contract employers in fulfilling theirobligations; and maintain a contract employee injury and illness log related tothe contractor’s work in the processareas.
