LICENSE OF TECHNOLOGY

BETWEEN

DELTA-T CORPORATION

AND

OTTER TAIL AG ENTERPRISES, LLC*

THIS AGREEMENT (hereinafter called LICENSE OF TECHNOLOGY or this “License”) made this 24th day of October, 2006 by and between Delta-T Corporation, a Virginia corporation, (“Delta-T”), and Otter Tail Ag Enterprises, LLC, a Minnesota limited liability company, ( “Owner”), each of which may be referred to individually as a “Party,” or jointly as the “Parties.”

WITNESSETH:

WHEREAS, Owner is building a 55 million gallon per year undenatured fuel ethanol plant using corn feedstock to be located in the State of Minnesota, County of Otter Tail, near the City of Fergus Falls, (the “Plant”), and

WHEREAS, Owner and Harris Mechanical Contracting Company, (“Prime Contractor”), have entered into an equipment, procurement and construction contract for construction of the Plant (the “Prime Contract”), and

WHEREAS, Delta-T has agreed to provide engineering and services related to construction of the Plant based on Delta-T’s proprietary technology under a subcontract with Prime Contractor (the “Subcontract”), but only on the condition that Owner enter into a license agreement with Delta-T for the use of the technology embodied therein, on the terms and conditions set forth herein,

NOW, THEREFORE, in consideration of the mutual covenants and conditions contained herein, the Parties agree as follows:

1. DELTA-T TECHNOLOGY

As used in this License, “Delta-T Technology” shall mean all data, technical information, trade secrets, inventions (whether patented or not and whether issued before or after the date of this License), know-how, procedures, processes, drawings, designs, methodology, models, inventions, specifications, Plant or equipment test and/or operating data, or other technical information and copyrights embodied in the Plant, used in the operation of the Plant, in equipment or in drawings, or included in any documents, drawings or other materials delivered electronically or otherwise by Delta-T to Prime Contractor or Owner under this License Agreement or the Subcontract. Delta-T Technology also includes, specifically but without limitation, the items listed on Exhibit A.

PORTIONS OF LICENSE OF TECHNOLOGY HAVE BEEN OMITTED PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT WHICH HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

2. GRANT OF LICENSE

2.1 License Grant: Owner acknowledges that Delta-T is and shall remain the sole owner of the Delta-T Technology. Delta-T hereby grants to Owner, subject to the conditions of this License, a non-exclusive, paid-up, non-transferable right to use in perpetuity the Delta-T Technology, without right to grant such rights to others except as otherwise set forth herein, solely for the purposes of:

A. construction and operation of the Plant, and

B. maintenance and optimization or enhancement of the Plant.

Owner agrees that it shall not use the Delta-T Technology for any other purpose. Optimization and enhancement (“Modification”), for this purpose, shall include de-bottlenecking, but shall not include expanding the physical dimensions of the distillation columns or molsieve vessels included in the Delta-T Technology, or adding to the original number of distillation columns or molsieve vessels specified in such design. Owner may not disclose any of the Delta-T Technology to (i) any third party that is listed on Exhibit B, or (ii) to any individual, group or company that is in the business of designing alcohol plants or parts thereof and that is not listed on Exhibit B (“Designers”), for the purpose of making any Modification, except that Owner may make such disclosure to any Designer to the extent, and only to the extent, necessary to permit such Designer to enable a Modification that was created without the disclosure of any Delta-T Technology by or on behalf of Owner, to interface with portions of the Plant designed by Delta-T.

2.2 Restriction on Assignment: This License is not assignable or otherwise transferable in any way, and any attempt to assign it in violation of this provision shall be null and void, except that (i) Owner may assign this License to a purchaser of substantially all of the assets of the Plant, or a sale of Owner as an entity, or of Owner’s membership interest in connection with the sale of such Plant as a going business, provided that Owner gives Delta-T written notice of such transfer at least thirty (30) days prior to the date on which it becomes effective, and (ii) Owner may pledge or grant a security interest in its interest in this License to its lender or lenders provided that no lender shall have a right to sell or otherwise transfer this License or any rights under it except in connection with the sale of the Plant as a going business, and provided further that any such lender must give Delta-T prior notice of such sale or transfer.

2.3 Payment: At such time as

(i)		Owner has paid Prime Contractor all amounts due to it under the Prime Contract in accordance with its terms;

(ii)		the Prime Contract is terminated (A) due to breach by the Prime Contractor or bankruptcy of the Prime Contractor, or (B) due to a Force Majeure Event (as defined in the Prime Contract) affecting Prime Contractor; or

(iii)		the Prime Contract remains in effect, has not been completed for reasons other than the fault of the Owner so that all amounts have not yet become due under such contract, but the Plant is capable of operating for commercial purposes; or

(iv)		Owner has paid Delta-T’s License Fee in full;

the license rights granted Owner under Section 2.1 above shall become irrevocable and shall continue in full force and effect notwithstanding any breach or default hereunder by Owner, provided that such continuation shall not limit or preclude any remedy Delta-T may have for damages. In no case, however, may Owner use the Delta-T Technology for any purpose unless it has first paid Delta-T Corporation a license fee of $2,100,000.00 for the Plant, less the amounts, if any, specifically enumerated and paid to Delta-T under the Prime Contract for the license fee. Furthermore, in the event of Termination of the Prime Contract, Owner and Delta-T will cooperate reasonably to facilitate Owner’s transition to a new prime contractor having a relationship with Delta-T as a subcontractor similar to the Delta-T relationship with the Prime Contractor.

Owner shall pay 70% of the Technology License Fee to Delta-T within 60 days of execution of this Agreement. The remaining 30% shall be paid upon the Plant successfully passing the Performance Test in compliance with the Performance Guarantees.

PERFORMANCE TEST PROTOCOLS

1. Performance Test Protocols

1.1 PRE-TEST PREPARATION

1.1.1Prior to the PERFORMANCE TESTS, the PLANT must have reached Mechanical Completion. In addition, DELTA-T must have run the PLANT or near design rate consistently for a period of seven (7) days, as evidenced by plant operational data provided to Delta-T by OWNER, before the PERFORMANCE TEST is initiated. Before commencement of PERFORMANCE TEST, DELTA-T shall notify OWNER in writing at least seven (7) Days prior to planned commencement of the PERFORMANCE TEST that all pre-test conditions have been satisfied, including the following:

· Adequate and competent supervision, personnel and resources for effective operation, maintenance and performance analysis of the PLANT, including laboratory analysis, temporary meters or other measuring devices and instrumentation specified as to accuracy and reproducibility by DELTA-T in advance of the PERFORMANCE TEST required to conduct and evaluate the PERFORMANCE TEST shall have been furnished. The PLANT shall be operated and maintained in accordance with the technical advice and instruction from the DELTA-T Operations Manual and on-site directives from DELTA-T, and otherwise within generally accepted practices within the fuel ethanol industry.

· The PLANT, its machinery, equipment, instrumentation and piping, shall all be clean lubricated where appropriate, leak tight, and ready to operate according to design specifications. All systems and appropriate checkouts and calibrations shall have been completed and documented by responsible PLANT technicians, contractors, and/or vendors. Analytical and any special test equipment and reagents will have been calibrated and made accurate.

· Cleaning (CIP) of the process equipment has been accomplished seven (7) days or less before the PERFORMANCE TEST per DELTA-T direction and standard procedures set out in the DELTA-T Operations Manual. All ingredients and supplies required to complete the test are on hand. This includes, but is not limited to, feedstock of corn (meeting specifications listed in Exhibit D Section 1.2) supplied in stable quantities sufficient to support PLANT operation at a rate up to 120% of the guaranteed fuel ethanol production rate, as well as sufficient steam and other utilities, enzymes, chemicals, and other ingredients of the type specified by DELTA-T in the Operations Manual and supplies to support PLANT operation at a rate up to 120% of the guaranteed fuel ethanol production rate.

· Adequate operation, analytical, and maintenance support shall be scheduled for the test period.

1.2 COORDINATION

1.2.1 DELTA-T shall coordinate the PERFORMANCE TEST with OWNER and Prime Contractor during the 24 hour/day around the clock PERFORMANCE TEST period. This coordination of the PERFORMANCE TEST activities will be handled by a DELTA-T representative designated to serve as DELTA-T’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. DELTA-T will also assign DELTA-T Shift Coordinators to support the operation during the test period.

1.2.2 OWNER 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.

1.2.3 DELTA-T shall direct its and Owner’s personnel in the operation of the PLANT in a manner consistent with the operating parameters provided in the Operations Manual.

1.3 CONDUCTING THE TEST

1.3.1 The DELTA-T 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 DELTA-T 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 three-day (72 hour) period of operation. During the Test period, the PLANT shall be operated by the OWNER in compliance with the instructions of DELTA-T and the Delta-T Operations Manual and instructions provided by DELTA-T, 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 DELTA-T. 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). If the Test Coordinator 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. DELTA-T 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 DELTA-T to such effect. If the PERFORMANCE TESTS have not been met, then OWNER shall issue a written notice to DELTA-T within one (1) day of completion of the PERFORMANCE TESTS indicating in what manner such Performance Guarantees have not been successfully completed.

1.3.2 If the 72-hour test period is interrupted for any reason within DELTA-T’s control or OWNER’S control, a new three-day 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. DELTA-T and OWNER shall stop the PERFORMANCE TEST if it becomes obvious that it cannot be carried to a satisfactory conclusion in the current attempt. If the PERFORMANCE TEST has been interrupted for reasons not attributable to

DELTA-T or other persons or factors within its control, and continues to be interrupted such that DELTA-T has spent a cumulative period of ten (10) calendar days on site since the commencement of the test, then OWNER shall compensate DELTA-T for the personnel that DELTA-T has on site. This compensation period shall begin on the cumulative 11^th day 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 DELTA-T or other persons or factors within its control. Compensation rates are provided in Exhibit B.1.

2. Analytical/Calculation Protocols

2.1 UNDENATURED FUEL ETHANOL QUALITY

METHOD:		Analyze samples according to DELTA-T provided procedures. The last test result before emptying day tank into main storage tank shall determine the quality for the batch. The average of all batch test results over the test period shall be used in determining the quality for the PEFORMANCE TEST. If the fuel ethanol in the day tank does not meet the quality specifications of Exhibit D, section 1.2.1, DELTA-T has the discretion to send it on to the main storage tank (on the theory that the blended product in the main storage tank will meet the quality specifications) the average of all batch test results shall be used to establish the blended quality. If the blended fuel ethanol does not meet quality specifications as a result of below quality product measured in one or more day tank batches the volume of the batch(s) shall not be included in ethanol production “rate” quantities used in calculating liquidated damages.
SAMPLE POINT:		Undenatured Fuel Ethanol Day Tank Storage
SAMPLE SIZE:		250 mls.
SAMPLE CONTAINER:		Nalgene
FREQUENCY:		Once per two (2) hours
SAMPLES RETAINED:		All
PREPARATION:		Standardize test reagents. Clean glassware and sample containers. Assure that reagents are of sufficient quality.
DOCUMENTATION:		Log results on a PERFORMANCE TEST Data Sheet.

2.2 Undenatured Fuel Ethanol Production Rate

METHOD:

The day tank will be manually measured every eight (8) hours to serve as the principal method of measurement of

		production volume, along with a final measurement of the day tank before the contents are sent to the main storage tank(s). In addition, flow totalizer readings will be taken from product meter or other measuring device mutually agreed upon between OWNER and DELTA-T at regular intervals as backup verification of the manual measurements. The total volume from the test meters will be adjusted to a volume equivalent 99.50wt% ethanol at 60^oF. Divide by the total number of test hours to determine the average rate over the test period. Multiply result by 1.05 to calculate Denatured Fuel Ethanol Rate.
SAMPLE POINT:		Product volumetric totalizing meter (with computer monitoring) after Product Receiver.
SAMPLE SIZE:		N/A
SAMPLE CONTAINER:		N/A

FREQUENCY:		Once per two (2) hours and at the end of each Day Tank batch.
SAMPLES RETAINED:		N/A
PREPARATION:		Certify that the flow meter is properly calibrated.
DOCUMENTATION:		Log results on a PERFORMANCE TEST Data Sheet and sign off by the OWNER and DELTA-T.

2.3 Undenatured Fuel Ethanol Yield

BASIS:		56 lb. per bushel corn containing 14.5% moisture and 72% dry starch and of 1% foreign material (by weight).
METHOD:		Record corn weigh belt totalizer readings to measure the accumulated meal weight. Measure the sample moisture and starch content. Convert total undenatured ethanol volume from the Rate Test to weight at 60^oF. 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.
TEST POINT:		Corn weigh belt
FREQUENCY:		Once per two hours

PREPARATION:

Certify that the weigh belt is properly calibrated

2.4 Process Electrical Consumption

METHOD:		Record electric meter readings at beginning of test and at the required frequency thereafter. Divide total Kwh for test period by total volume of undenatured ethanol produced to determine average Kwh per gallon. Average results of all calculations for test periods to determine the process electrical power consumption value for PERFORMANCE TEST.
TEST POINT:		Electric power meter types and locations as established by Delta-T, and as necessary to isolate process consumption.
FREQUENCY:		Once per 24 hours
PREPARATION:		Isolate process electrical consumption activities during test period.
DOCUMENTATION:		Log results on a PERFORMANCE TEST Data Sheet

2.5 NATURAL GAS CONSUMPTION

METHOD:		Record plant natural gas meter totalizer readings in MCF over test period. Obtain higher heating value specification for gas 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. Quantities of natural gas will be adjusted to 1,000 btu/ft³ (70° F, 1 atm) and 10% DDGS moisture respectively before the calculation is made. Average results of all calculations for test period to determine natural gas consumption value for Acceptance Test.
TEST POINT:		Plant gas meter
FREQUENCY:		Once per two (2) hours
PREPARATION:		Certify gas meter is properly calibrated and suspend all non-process use of natural gas.
DOCUMENTATION:		Log results on an “Acceptance Test Data Sheet.”

2.6 CALCULATION PROTOCOL

All calculations will be based on actual measured data taken during the test period. For any given sample period, the average value during that period will be determined by the average of the measured data points for that sample period. The liquidated damages, if any, will be determined using the data collected for each individual sample period and averaged over the PERFORMANCE TEST period. All samples shall be taken in duplicate and OWNER and DELTA-T shall each retain one sample. OWNER shall analyze one of the duplicates; the second shall be reserved for use in case of a disagreement. OWNER shall cause such analyses to be conducted at the Plant during the PERFORMANCE TEST period and in the presence of the Test Coordinator or such coordinator’s designee, and Owner and Lender’s Independent Engineer if they are present. In case of disagreement, a referee laboratory shall be selected by agreement between OWNER and DELTA-T, and the cost of such referee laboratory shall be paid by the party or parties not substantiated by the referee. The findings of this referee laboratory shall be accepted as final.

2. Right to Cure; Limitation on Liquidated Damage Claim

In the event that one or more of the performance criteria set forth in Section 1.2 above are not satisfied, DELTA-T shall have the right at its expense to require a test of the degree of accuracy of the testing equipment and testing methods and procedures. If the variation from the guaranteed rates is less than or equal to the demonstrated margin of error of the relevant PERFORMANCE TEST, then OWNER shall have the right (but not the obligation) to make improvements in the testing equipment, at OWNER’S cost provided the variations are not attributable to DELTA-T, and require that DELTA-T repeat the relevant PERFORMANCE TEST. If OWNER does not make such improvements, then DELTA-T shall have the right to do so and OWNER shall reimburse DELTA-T for the cost of making the required improvements. If the performance criteria set forth in Exhibit D, Section 1.1 are not satisfied for reasons not attributable to DELTA-T or other persons or factors within DELTA-T’s control, then OWNER may, at its option, remedy the defect or deficiency and have the PERFORMANCE TESTS re-run at any time within three (3) months of the date of commencement of the first ACCEPTANCE TEST, or pay to DELTA-T the remaining unpaid portion of the Fee.

Within said three (3) month period, DELTA-T shall take whatever action is reasonably necessary and consistent with sound engineering and construction practices to cause the PLANT to satisfy the performance guarantees in Section 1.2. Within said three (3) month period, DELTA-T may re-run the PERFORMANCE TEST one or more times before paying liquidated damages as set forth in Section 3.1 below as a result of failing to meet the guarantees set forth in Section 1.2 above. Any claims for liquidated damages must be in writing and shall be submitted to Delta-T no later than thirty (30) days from the date of completion of the last PERFORMANCE TEST, which requires the payment of liquidated damages.

The Parties acknowledge and agree that the terms of this Contract with respect to liquidated damages, including those payable under this Exhibit D, are fair and reasonable considering the damage Owner would sustain in the event of DELTA-T’s failure to perform as required under this Contract, 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 damages and not as penalty.

3. Liquidated Damages and Maximum Damages for Process Guarantees

3.1 Amount of Damages:

If a defect in the BASIC PROCESS DESIGN or the Delta-T Technology causes the PLANT to fail one or more of the process performance guarantees set forth in Section1.2 above during a PERFORMANCE TEST as provided herein, and DELTA-T has not been able to correct the defect and pass all components of the PERFORMANCE TESTS within the time set forth at Section 2 above, then OWNER shall be entitled to liquidated damages based on the net amount due as allocated below up to a maximum cumulative amount of $*.

The sum of the countervailing factors, determined as set forth under Section 3.2 below, shall be deducted from the sum of the damages determined thereunder. In no case, however, shall OWNER have any obligation to pay DELTA-T as a result of such calculation. If the countervailing factors are greater than the damages the calculation the liquidated damages shall be deemed to be zero and neither Party shall have any obligation to the other as a result of the PERFORMANCE TEST.

3.2 Amount of Damages and Countervailing Factors

Fuel Ethanol Yield:

* per 0.01 lb of anhydrous un-denatured ethanol per lb of convertible starch that the PERFORMANCE TEST results show lower or higher than the guaranteed ethanol yield listed in Paragraph 1.2 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 example, if the PERFORMANCE TEST average ethanol yield is 0.505 pounds of un-denatured anhydrous ethanol per pound of starch, the amount included in the liquidated damages calculation for this component would be ((0.510 – 0.515) = -.005/.01 = -.05 < |1| = 0 x $*) = $0

This example illustrates the fact that only full increments of positive or negative variances count towards the liquidated damages financial calculation. Anything less than this numerical increment is considered to be too close to the tolerance of measurement to be meaningful. An increment of .005 is less than .01, so it is rounded down to zero. As another example, an increment of .015 would be rounded down to .01.

Fuel Ethanol Production Rate:

$* per 10 US gallons per hour of un-denatured ethanol that the PERFORMANCE TEST results show lower or higher than the guarantee ethanol production rate listed in Paragraph 1.2 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 be a countervailing factor.

For example, if the PERFORMANCE TEST average ethanol production rate is 10 US gallons per hour over the guarantee rate, the amount included in the liquidated damages calculation for this component would be (10gph) = 10/10 = 1.0 x $* =*

*	PORTIONS OMITTED PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT WHICH HAS BEEN FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.

NATURAL GAS CONSUMPTION:

* per each 100 BTU per US gallon of un-denatured ethanol that the PERFORMANCE TEST results show higher or lower than guaranteed natural gas consumed for the boiler and DDGS dryer listed in Paragraph 1.2 above. To the extent the consumption is higher the resulting number shall constitute damages. To the extent that it is lower the resulting amount shall be a countervailing factor. For example, if the PERFORMANCE TEST average natural gas consumption is 37,000 BTU per gallon of un-denatured ethanol, then the amount included in the liquidated damages calculation for this component would be (36,000 – 37,000) = -1,000/100 = (-10 x $*=*. a penalty.

Process Electrical Consumption:

* per each 0.01 kWh per US gallon of un-denatured ethanol that the PERFORMANCE TEST results show higher or lower than the guaranteed power consumption production rate listed in Paragraph 1.2 above. To the extent the consumption is higher the resulting number shall constitute damages. To the extent that it is lower the resulting amount shall be a countervailing factor.

For example, if the PERFORMANCE TEST average electric process power consumption excluding utilities is 0.98 kwh per gallon of un-denatured ethanol produced, then the amount included in the liquidated damages calculation for this component would be (1.0 – 0.98) = 0.02/0.01 = 2 x $*=*, a countervailing factor.

If we assume the example performance numbers set forth above to illustrate a theoretical liquidated damage calculation, there would be no liquidated damages paid because the cumulative sum of all the performance calculations is positive, as shown below:

Production Rate Deviation	$*	Countervailing Factor
Ethanol Yield Deviation	$	0
Natural Gas Consumption Deviation	(*)	Damages
Electric Power Consumption Deviation	$*	Countervailing Factor

Subtotal	$*	Net Positive Sum

Liquidated Damages	-0-

3.3 Damages Reasonable

The Parties acknowledge and agree that the terms of this Agreement with respect to liquidated damages, including those payable under this Exhibit D, 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 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 damages and not as a penalty.

Definitions:

Mechanical Completion: The completion of construction activities essential to the safe and proper operation of the plant, as more fully listed below.

Commissioning: The checking 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 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, DELTA-T will notify OWNER that 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.

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 facility.

The following lists indicate the activities or events, which take place in each of the phases described.
