- 34 -

4.40           NERC Critical Infrastructure Security Management Controls.  Contractor shall at all times comply with Owners’ security management information protection program set forth in in this Section 4.40 implementing CIP-003-1, R-4 (as may be superseded by CIP-003-2 or otherwise) of NERC’s Reliability Standards for Bulk Electric Power Systems of North America.  In addition, if and to the extent that the Work requires access to: (i) assets of Owners or (ii) areas of the Existing Facilities that are located within the physical security perimeters described in Exhibit S-3, without limiting Contractor’s obligations under Article 18 with respect to Confidential Information, Contractor shall comply with Owners’ programs that implement CIP-004-1, R1 through R4 (as may be superseded), including the following:

(a) If any of personnel of Contractor or a Subcontractor requires key card access to a restricted area or electronic access to a protected system, Contractor shall identify such individual to the individual designated by Owners in Exhibit S-3 and provide such documentation and information required by Owners.  All such individuals are subject to background checks from time to time.  Any such individual may also be subject to periodic information requests to maintain access. Access to any restricted area or protected system by any individual for whom Contractor is responsible without strict adherence to Owners’ protection program is a material breach of this Agreement.  Owners are entitled to deny access to any individual for whom access is proposed if such individual at any time does not meet Owners’ requirements under this program, including execution of waivers and other documentation required by Owners as a condition of granting or maintaining such access;

(b) As a condition of Owners granting access to any individual for whom Contractor proposes access, such individual must take (and retake as necessary) all NERC-related training required by Owners.  Owners may require such individual to demonstrate competence in the subject of such training as a further condition to gaining or maintaining access; and

(c) If any individual that was granted key card access to a restricted area or electronic access to a protected system no longer requires such access, Contractor shall immediately collect such individual’s key card and give notice of the individual’s name, the date on which access was no longer needed and return the key card to the individual designated by Owners in Exhibit S-3.

Contractor certifies for itself and its Subcontractors and their respective representatives who may be granted access to “critical energy infrastructure information” (“CEII”) as defined in 18 C.F.R. § 388.113(c)(1) or any successor provision that (1) it and each of its representatives are aware of the requirements of 18 C.F.R. Part 388 with regard to CEII and (2) it has no reason to believe that it or its representatives would be restricted from access to CEII.  To the extent applicable, a disclosure (inadvertent or otherwise) of CEII by Contractor, its Subcontractors or any of their respective representatives must be appropriately addressed by Contractor pursuant to 18 C.F.R. § 358.7 or any successor provision.

The foregoing requirements set forth in this Section 4.40 constitute the “NERC Requirements” applicable to Contractor, its Subcontractors and any others for whom Contractor is responsible.  The obligations established by this Section 4.40 are continuing obligations and survive the expiration or early termination of this Agreement.  Owners have the right to audit and inspect any and all such information regarding compliance or non-compliance with the NERC Requirements in accordance with Section 25.9.1.  Contractor, immediately upon the request of Owners, shall confirm destruction of any documentation relating to the NERC Requirements received from or regarding Owners or the Existing Facilities.  If Contractor has any questions about the nature of its obligations under this Section 4.40 it shall promptly contact the individual designated by Owners in Exhibit S-3 prior to proceeding to take any action that could risk non-compliance with the NERC Requirements.

- 35 -

4.41        Salvaged Materials.  Exhibit B specifies certain materials to be salvaged by Contractor for recycling.  Owners shall have title to all such salvaged materials, whether resulting from demolition or new construction activities.  Contractor shall coordinate the recycling of such materials with Owners’ recycling vendor and Owners’ Representative.  Contractor shall arrange with Owners’ recycling vendor the delivery and pick-up of recycling bins for such salvaged materials to the extent that such salvaged materials can be placed in bins.  If any of the salvaged materials cannot be placed into bins, Contractor shall neatly store such salvaged materials at a location or locations directed by Owners’ Representative until pick-up, and Contractor shall arrange for such pick-up with Owners’ recycling vendor.  All revenues from the recycling of such salvaged materials shall belong to Owners.

ARTICLE 5

OWNERS RIGHTS, DUTIES & OBLIGATIONS

5.1           Key Personnel.  Owners shall designate, from time to time, one or more individuals who will act on Owners’ behalf, in connection with the Work, together with the scope of their authority.  Among such designees there must be appointed a principal representative of Owners (the “Owners Representative”), who will be Owners’ authorized representative, and who will receive and initiate all communications from and with Contractor and who will be authorized to render decisions related to the Work and bind Owners.

5.2           Owners’ Review.  Owners will be entitled to review, comment on, evaluate, or approve the Design Documents and other submittals as provided in Exhibit B.  Contractor shall consider Owners’ comments in good faith; provided, however, Owners will not have any responsibility or liability for the accuracy or completeness of such documents, for any defects, deficiencies, or inadequacies therein or for any failure of such documents to comply with the requirements set forth in this Agreement, the responsibility for all of the foregoing matters being the sole obligation of Contractor.  Contractor shall advise Owners in writing of the disposition of each of the comments.

5.3           Owners Provided Items.  Owners, at their expense, shall provide: (i) construction electric power and a potable water source.  Items to be provided by Owners prior to Substantial Completion, including items necessary for start-up, are specifically identified, limited in quantity, and scheduled as set forth in Exhibit O. Additional quantities shall be made available by Owners, subject to availability, at Contractor’s expense.

5.4           Right to Apply Monies.  Owners shall have the right to deduct from any funds or monies due or to become due to Contractor (or draw on the Retainage) any amounts actually due to Owners from Contractor as a result of any losses, expenses, damages, obligations, or liabilities for which Contractor is responsible pursuant to the terms and provisions of this Agreement.

- 36 -

5.5           Access and Inspection.

5.5.1           Access to Site.  Owners shall provide reasonable non-exclusive access to the Job Site (as shown in Exhibit S-2), other portions of the Big Stone Site, and the Existing Facilities on which Work is to be performed to Contractor and its Subcontractors commencing upon issuance and acknowledgement of the Notice to Proceed, subject to Applicable Law, applicable Big Stone Site regulations, and the terms of this Agreement.  Notwithstanding the foregoing, Contractor may not commence “construction” within the meaning of Owners’ Permits prior to the mobilization date set forth in Exhibit B, Section 013216, without Owners’ prior written consent.  Prior to issuance of the Notice to Proceed, Contractor may have access to the Job Site or other portions of the Big Stone Site upon reasonable advance notice to Owners and at reasonable times for purposes expressly approved by Owners, subject to Big Stone Site regulations and the terms of this Agreement.  Owners will be entitled to restrict Contractor’s access to or activities on the Big Stone Site prior to issuance and acknowledgement of the Notice to Proceed and Contractor will not be entitled to assert any claim for relief under Article 9 or Article 10 on account thereof.  Until issuance and acknowledgement of the Notice to Proceed, unless Contractor has received the prior written consent of Owners, Contractor shall not engage in any construction work upon the Big Stone Site.

5.5.2           No Relief.  No inspection or review of, or failure to inspect or review, the Work or any portion thereof by Owners or any other Person on behalf of Owners will relieve Contractor of its obligation to properly execute and complete the Work.  Inspection by Owners will not be deemed to be supervision or direction by Owners, and is only for the purpose of attempting to confirm for Owners’ purposes that the Work conforms to the requirements of this Agreement.

5.6           Owners Permits.  Owners are responsible for obtaining Owners Permits.

5.7           Right to Carry Out the Work.  If Contractor defaults under this Agreement or neglects to carry out the Work in accordance with this Agreement and fails within a seven (7) Day period after receipt of written notice from Owners to take steps to commence and continue curing such default or neglect with diligence and promptness, Owners, without prejudice to any other rights or remedies Owners may have under this Agreement, including declaring Contractor in default, and with or without terminating this Agreement, may correct such deficiencies at Contractor’s expense, (including Owners’ internal, general, and administrative expenses) and Owners shall have the right to: (i) charge against the Target Price an amount equal to the expenditures incurred by Owners in so doing; and/or (ii) utilize Retainage.

5.8           Rights Not Limited.  The rights and remedies provided in this Article 5 are in addition to, and not in limitation of, any other rights or remedies otherwise available to Owners under this Agreement.

5.9           Operating Personnel.  At such time as Contractor has achieved Mechanical Completion, Owners will commence hot commissioning of the Work.  Owners shall operate the Unit from and after Mechanical Completion with its normal complement of personnel.  Contractor shall communicate with supervisory personnel identified by Owners to convey any requests with which it wants Owners to comply with respect to the operation of the Work during commissioning and hot testing.  Owners shall use reasonable efforts to operate the Unit in accordance with such requests to the extent such requests are consistent with Good Utility Practices and comply with Applicable Law.  If Contractor requests Owners’ operation of the Unit and such request is responsible for damage to the Unit or the Work, Contractor shall: (i) reimburse Owners on demand for correction of such damage within the Unit; (ii) correct damage within the Work; and (iii) pay liquidated damages for each Outage Day in accordance with Section 7.1.  Contractor understands that the Unit is a critical generating resource for Owners and consequently Contractor will exert maximum efforts not to make requests that are inconsistent with Owners’ requirement to maximize Unit operations on an unrestricted basis.

- 37 -

5.10           System Needs.  Inasmuch as the Unit is a critical generating resource for Owners, if Owners determine that system needs require the Unit to operate after Mechanical Completion but prior to Substantial Completion, Owners will advise Contractor in writing and Owners will be entitled to put the Unit into service.  To the extent such Unit operations materially interfere with Contractor’s ability to achieve Substantial Completion, such interference will constitute an Excusable Event.

5.11           Contractor’s Personnel.  Owners have the right to object to any representative or Person employed or engaged by Contractor that engages in misconduct, is believed by Owners to lack competence for the tasks assigned, or is negligent while on the Job Site or the Big Stone Site.  Contractor shall remove such Person from the Job Site or the Big Stone Site, as applicable upon receipt of Owners’ written notice.  Any cost for replacement Persons will be at Contractor’s expense and shall not be included in the Cost Reimbursable Portion.  The rights of Owners under this Section 5.11 are in addition to the rights of Owners with respect to the personnel pursuant to Section 4.6.

5.12           Revenue.  Owners are entitled to all energy (steam and electrical), capacity and ancillary attributes that result from electrical generation of the Unit and all revenue derived therefrom.

ARTICLE 6

PROJECT SCHEDULE

6.1           Commencement.  Contractor acknowledges that it will commence performance of the Work upon receipt of the Notice to Proceed in accordance with the requirements of this Agreement and that it will continuously and diligently fulfill its obligations under this Agreement.  Exhibit D sets forth the Project Schedule indicating the dates for the start and completion of the various stages of the Work.  Contractor shall strictly adhere to the Project Schedule.  Owners reserve the right to direct Contractor to reschedule the order and rate of progress of performance of the Work so as not to interfere with the performance of work by Owners and/or other contractors.  In the event Owners redirect Contractor’s Project Schedule, Contractor may be entitled to a Change Order in accordance with Article 10.

6.2           Project Schedule Update.

6.2.1           Without altering, revising, or otherwise changing the scheduled Installation Start Date, the Guaranteed Mechanical Completion Date, the Guaranteed Substantial Completion Date, or the Guaranteed Final Completion Date, Contractor shall submit, with the monthly status report submitted pursuant to Section 4.24.1, electronic and updated hard copy of a total project integrated Project Schedule, including critical path activities interconnected by schedule logistics, in Level 3 Primavera P6® format (fully logic-tied and resource loaded) and meeting the requirements set forth in Exhibit B, Section 013216, to Owners for Owners’ review and comment.  All extensions of the Project Schedule to which Contractor is entitled shall be determined by the impact of the delay giving rise to the change in the critical path, as shown on the Project Schedule.

- 38 -

6.2.2           If at any time during the performance of the Work, Contractor’s progress does not keep pace with the requirements of the Project Schedule, to the extent of Contractor’s fault or responsibility Owners may order Contractor to take steps to improve its progress without a change to the Target Price.  Neither such notice by Owners, nor Owners’ failure to issue such notice, shall relieve Contractor of its obligation to perform in accordance with the Agreement, including completion of quality Work in the timeframe required by the Project Schedule.  Failure of Contractor to comply with the notice of Owners may be grounds for determination by Owners that Contractor is not pursuing the Work with such diligence as shall assure completion within the times specified.  Upon such determination, Owners may invoke their Right to Carry Out the Work, as described in Section 5.7 of this Agreement.

6.3           Turnover of the Systems.  Not less than one hundred twenty (120) Days prior to commencing the turnover process contemplated by this Article 6, Contractor shall provide a detailed written turnover and start-up plan to Owners for their review and comment.  Such plan must include: a complete listing of the Systems along with a scheduled turnover date for each such System and a schedule of documents to be included in the System Turnover Package that will accompany the System being turned over.  Each System Turnover Package must be properly completed and include sufficient checkout and operation information to clearly indicate that the System has been completely checked out and meets the requirements of Exhibit B.  The data provided in each System Turnover Package must be complete and compatible for insertion into Owners’ hold card system or lock-out tag-out procedures, as applicable.  Owners will have thirty (30) Days to review such plan and provide written comments to Contractor.  Contractor will promptly address such comments and resubmit the plan until such time as Owners approve the plan.  Owners and Contractor will mutually agree on the final turnover and start-up plan prior to its implementation.  Thereafter, Contractor’s turnover of Systems will be accomplished as follows:

6.3.1           Ready for Turnover.  When Contractor deems that it has achieved completion of construction of a System in accordance with this Agreement, including static integrity tests, alignment, electrical continuity tests, lubrication, and demonstration of readiness for operation as appropriate (but exclusive of Punch List Items, final vendor reports, manuals, and other information not necessary for start-up), Contractor shall notify the Owners Representative, in writing, that the System is ready for turnover to Owners, which notice must be accompanied by the applicable System Turnover Package meeting the requirements of this Agreement.

- 39 -

6.3.2           Turnover Acknowledgment.  Owners will agree that the System is ready for turnover in writing (“Turnover Acknowledgment”) within seven (7) Days of receipt by Owners Representative of notification from Contractor (the “Owners Review Period”), unless Owners reasonably believe that: (i) the System Turnover Package does not comply with the requirements of this Agreement or (ii) the System (a) contains deficiencies, defects, or non-conformities that preclude safe testing, safe commissioning, or safe operation; (b) has not been prepared, flushed, or cleaned as necessary or appropriate; (c) requires Work that has not been completed and which does not constitute a Punch List Item; or (d) materially differs from the System required under this Agreement.  Owners and Contractor must develop a Punch List and endeavor to ensure that the Punch List contains all deficiencies and incomplete items of Work with respect to the System submitted for Turnover Acknowledgment. Notwithstanding the foregoing, if the turnover of a System by Contractor is not made in accordance with the agreed upon turnover Project Schedule and as a result Owners are unable to accept or reject such System within the Owners Review Period, Owners and Contractor will mutually agree upon a reasonable extension of the Owners Review Period for the affected Systems, which extension will reflect the nature of the affected System.  Turnover Acknowledgment and the provision of operating personnel neither constitutes acceptance of any System, Owners’ acceptance of care, custody, or control of such System, nor any transfer of control to Owners, including responsibility for commissioning, start-up, testing, operations, or maintenance.

6.3.3           Deficiencies.  If Owners reasonably believe that any of the circumstances set forth in clauses (i) or (ii) of Section 6.3.2 exist with respect to a System submitted for Turnover Acknowledgment, Owners will so notify Contractor in writing during the Owners Review Period, stating the deficiencies noticed or the incomplete items of Work, as applicable.  When Contractor deems it has remedied such deficiencies or completed such items of Work, as applicable, Contractor will then again notify Owners Representative as provided in Section 6.3.1.  This procedure will be repeated until Owners issue the Turnover Acknowledgment for such System.  Nothing contained herein will prevent Owners from identifying any Defects, deficiencies, incomplete Work, or Punch List Items if discovered after Turnover Acknowledgment of any System.

6.4           Installation Outage.

6.4.1           Marshaling.  Contractor may not commence to accomplish Work that requires the Unit to be off-line unless its workforces, its Subcontractors’ workforces, Contractor Supplied Materials and Equipment, Consumables, and Construction Aids necessary for the performance of such Work have been fully marshaled and are present at the Job Site prior to the commencement of the outage during which such Work will be performed (the “Marshaling Requirement”).  Contractor’s Work to be performed during the Installation Outage must, however, be coordinated with the work to be performed by Owners during such outage and may not start before the Installation Start Date, except as approved by Owners.

- 40 -

6.4.2           Installation Outage.  Contractor shall exercise its best efforts such that all Work that requires the Unit to be off-line will be achieved during the Installation Outage.  If achievement of such Work is in jeopardy in the reasonable judgment of Contractor or Owners, Contractor shall promptly prepare and implement, in good faith, a detailed recovery plan such that the performance of the Work can progress in accordance with the Project Schedule.  If the inability to meet the Project Schedule is caused without any material contribution by Contractor or its Subcontractors, then Contractor will be entitled to a Change Order increasing the Target Price by an amount equal to its costs related to preparing and implementing the recovery plan in accordance with Article 10.

6.4.3           Extension of Installation Outage.  If Contractor fails to complete all Work that requires the Unit to be off-line within the Installation Outage and the Unit cannot be placed in service and operate as a consequence of Contractor’s failure to complete such Work, liquidated damages will be assessed against Contractor, which liquidated damages will be calculated as if they had been incurred under Section 7.1, for each Day, or part thereof (without proration), from and after the first Day following the Installation Outage until the Day that such Work has been completed.  If Contractor requires additional time to complete such Work and requires that the Unit be out of service in order to complete such Work, at Contractor’s request, Owners will schedule the required number of Days for Contractor to complete the Work and Contractor will be assessed liquidated damages for each such Day, as if such liquidated damages were incurred under Section 7.1.  Contractor will withdraw from the Unit so as not to delay Start-up as planned by Owners.  Contractor is obligated to use its best efforts to complete such Work notwithstanding the occurrence of an event of Force Majeure (other than an event of Force Majeure occurring after it has met the Marshaling Requirement) and without adjustment of the terms of this Agreement on account thereof.  Contractor recognizes that the date of the scheduled Installation Outage is not subject to change except in Owners’ sole discretion.

6.4.4           Operation After Installation Outage.  Whether or not such Work has been completed at the end of the Installation Outage, Contractor will leave the Work in a condition that will allow Owners, exercising Prudent Utility Practices, to utilize the Unit, it being understood by Contractor that the Work, and the Unit, will run on a commercial basis as needed following the Installation Outage.

6.5           Mechanical Completion.

6.5.1           Achievement.  Contractor shall successfully achieve Mechanical Completion on or before the Guaranteed Mechanical Completion Date.

- 41 -

6.5.2           Mechanical Completion.  If timely achievement of Mechanical Completion by the Guaranteed Mechanical Completion Date is in jeopardy in the reasonable judgment of Contractor or Owners or if it is not timely achieved, Contractor shall promptly prepare and implement, in good faith, a detailed recovery plan and accelerate the Work such that the performance of the Work can progress in accordance with the Project Schedule.  If the inability to meet the Project Schedule is caused without material contribution by Contractor or its Subcontractors, then Contractor will be entitled to a Change Order increasing the Target Price by an amount equal to its costs related to preparing and implementing the recovery plan and accelerating the Work in accordance with Article 10.  Within seven (7) Days after receipt by Owners of written notice from Contractor certifying that Contractor has satisfied the requirements for Mechanical Completion (other than issuance of the Certificate therefor by Owners), Owners shall determine whether the applicable requirements have been achieved and shall either issue the Certificate of Mechanical Completion or give notice to Contractor in writing of Defects in the Work (other than Punch List Items), of which Owners then have knowledge.  Owners are obligated to issue the Certificate of Mechanical Completion within such seven (7) Day period if Contractor has satisfied the requirements of Mechanical Completion (other than issuance of the Certificate therefor by Owners).  Upon receipt of a written notice of the reasons why Contractor has not achieved Mechanical Completion from Owners, Contractor shall promptly perform corrective measures to eliminate any Defects or deficiencies in the Work and shall thereafter provide another written notice to Owners containing the applicable certification set forth above.  Owners shall, within two (2) Business Days after receipt of such written notice, and after each subsequent written notice as may be required, determine whether the applicable requirements have been achieved and either issue the Certificate of Mechanical Completion or advise Contractor of any Defects or deficiencies (other than Punch List Items) remaining in the Work that prevent achievement of Mechanical Completion.

6.6           Re-Setting of Work.  During those periods after Substantial Completion, Contractor shall perform whatever Work is necessary, including re-setting of Equipment and repairs of damage or modifications caused by testing, to return the Work or relevant portion thereof to the normal operating control settings and configurations; provided, however, Contractor is not entitled to require that the Unit be taken out of service or operate on a restricted basis.

6.7           Substantial Completion.  Contractor shall successfully achieve Substantial Completion on or before the Guaranteed Substantial Completion Date.  At such time as Contractor, in good faith, believes that it has completed the requirements necessary for the achievement of Substantial Completion it shall give written notice of its belief to Owners. As soon as practicable, but in any event within five (5) Business Days after receipt of notice by Owners, Owners shall either issue the Certificate of Substantial Completion or reject Contractor’s notice, in which case it shall state its reasons for rejection.  Such procedure shall be repeated until Contractor submits a notice demonstrating that it has fulfilled the requirements necessary to achieve Substantial Completion.  Owners are obligated to issue the Certificate Substantial Completion within the five (5) Business Day period set forth above if Contractor has satisfied the requirements of Substantial Completion.

- 42 -

6.8           Possession and Control.  On the earlier of Substantial Completion or Early Operation, Owners shall take and thereafter be responsible for the care, custody, control, operation, and maintenance of the Work.  Following transfer of possession and control of the Work to Owners, Contractor (and its Subcontractors) will have reasonable access to the Work or the Unit as part of the Work to complete any Work still remaining to be performed hereunder; provided, however, Contractor, Subcontractors and Owners will be required to complete any and all Work required to achieve Substantial Completion or Final Completion in a manner consistent with the operational requirements of the Unit (as improved by the Work following the completion of the Work) as directed by Owners.  In no event will Owners be required to take the Unit out of service or otherwise adversely affect Unit operations, except as set forth in this Section 6.8.  Promptly upon achievement of Substantial Completion, Contractor shall advise Owners whether completion of the Work required to achieve Final Completion will require a partial or complete shutdown of the Unit and the Work or the imposition of operating restrictions on the Unit.  If any such actions are required, Owners will identify a scheduled outage period of the duration requested by Contractor which, in no event, will exceed seven (7) continuous Days within which outage Contractor will be entitled to perform necessary Work; provided, however, any such period will not be scheduled during a peak period or during peak hours.  Contractor and Owners will coordinate their respective scopes of work to be performed during such outage.  Outages and operations are at all times also subject to the requirements of any applicable transmission operator.  Any imposition of operating restrictions or scheduled outage, if necessary, must be arranged and be completed prior to the Guaranteed Final Completion Date.  If for any reason a partial or complete shutdown of the Unit and the Work is required after Substantial Completion for Contractor to complete the Work and Owners have no scope of work required to be performed during such outage, Contractor will be assessed liquidated damages for each Day of such outage, as if such liquidated damages were incurred under Section 7.1.

6.9           Final Completion.  Contractor shall successfully perform all of the Work and obligations (except obligations requiring future performance, e.g., warranty and indemnification obligations) and shall achieve Final Completion on or before the Guaranteed Final Completion Date.  At such time as Contractor, in good faith, believes that the requirements of Final Completion have been met, Contractor shall give notice to Owners, together with reasonable substantiating documentation thereof.  Within ten (10) Days after receipt by Owners of such notice from Contractor, Owners will determine whether the requirements of Final Completion have been achieved.  If Owners agree with Contractor’s notice, within five (5) Business Days of the receipt of Contractor’s notice Owners shall issue the Certificate of Final Completion.  If, however, Owners believe that Final Completion has not been achieved, Owners shall give notice to Contractor to that effect, with reasons for such belief, within the five (5) Business Day period, and, upon receipt of such notice from Owners, Contractor shall promptly take corrective action to fulfill the requirements of Final Completion.  Contractor shall thereafter provide another notice to Owners when it believes that Final Completion has been achieved and the above-described procedures will be repeated until Final Completion is achieved.  Owners are obligated to issue the Certificate of Final Completion within five (5) Business Days of receipt of Contractor’s notice if Contractor has satisfied the requirements of Final Completion.  Nothing in this Section 6.9 shall relieve Contractor of its obligation to achieve Final Completion by the Guaranteed Final Completion Date.

6.10           Maintenance Outage.  Owners will inform Contractor as soon as practical if a maintenance outage (other than the Installation Outage) is scheduled for the Unit.  With Owners’ permission, Contractor may use the period established by Owners within such maintenance outage to perform Work.  Owners may change the schedule for commencement of a maintenance outage without notice.  Owners will specify in writing and Contractor will honor the dates and times for and restrictions in Contractor’s access to the Unit for the performance of such Work.  If Contractor causes Owners to extend a maintenance outage beyond the scheduled duration, then each Day of such extension will constitute an Outage Day and Contractor shall compensate Owners for any such extension at the rate established for liquidated damages pursuant to Section 7.1.

- 43 -

6.11        Contractor Requested Outage.

6.11.1           Forced Outages.  Contractor may request permission to perform Work requiring access to the Unit during a forced outage of the Unit.  In such event, Contractor may give notice that it wishes to use a portion of such forced outage to perform Work.  Owners will be entitled to grant or deny access to Contractor in its sole discretion.  If access is granted, Owners will specify in writing and Contractor will honor the dates and times, for and restrictions in Contractor’s access to the Unit for the performance of such Work.

6.11.2           Additional Access.  Contractor may also request access at times other than the Installation Outage or as provided in Section 6.8, 6.10, and 6.11.1.  If: (i) Contractor’s request for additional outage time requires the Unit must be taken out of service or operated on a restricted basis, Contractor will compensate Owners for each Outage Day at the rate established for liquidated damages pursuant to Section 7.1.

6.11.3           Delay.  If Contractor fails to properly withdraw from any outage on schedule and thereby causes a delay in Start-Up, as applicable, then liquidated damages pursuant to Section 7.1 will apply.

8.5          Deviations From the Target Price.If the Total Construction Cost is less than or greater than the Target Price, as adjusted pursuant to this Agreement, the savings or overage, as applicable, shall be shared by Contractor and Owners in the percentages set forth in the table below.  Overage/underage is computed by beginning at zero and working up (or down if it is an underage) the table to the next category after the maximum band-width in the category is reached.  For a 6% overage, e.g., the first 5% is computed using the shared percentages in the initial (0-5%) category and then the next 1% using the next category’s percentages (5-10%) and the two results are added together for the total amount.

- 55 -

Over/Under Target Price	Contractor Share	Owners Share
+ Over >20% +	[**]%	[**]%
+ 10% to 20%	[**]%	[**]%
+ 5% to 10%	[**]%	[**]%
+ 0 to 5%	[**]%	[**]%
- 0 to - 5% -	[**]%	[**]%
- 5% to - 10%	[**]%	[**]%
- 10% to - 20%	[**]%	[**]%
Under > -20% +	[**]%	[**]%

For example, assuming the Target Price is $100,000,000, then:

(A)  If the Total Construction Cost is $106,000,000 (a 6% overage):

Contractor’s Share would be [**]% of the first 5% of the overage and [**]% of the next 1% of the overage:

Contractor’s Share = ([**] x $5,000,000) + ([**] x $1,000,000) = $[**].

Owners’ Share, which Owners would pay to Contractor, would be [**]% of the first 5% of the overage and [**]% of the next 1% of the overage:  .

Owners’ Share = ([**] x $5,000,000) + ([**] x $1,000,000) = $[**].

(B)  If the Total Construction Cost is $88,000,000 (a 12% underage):

Contractor’s Share, which Owners would pay to Contractor, would be [**]% of the first 5% of the underage, [**]% of the next 5% of the underage, and [**]% of the next 2% of the underage:

Contractor’s Share = ([**] x $5,000,000) + ([**] x $5,000,000) + ([**] x $2,000,000) = $[**].

Owners’ share would be [**]% of the first 5% of the underage, [**]% of the next 5% of the underage, and [**]% of the next 2% of the underage:

Owners’ Share = ([**] x $5,000,000) + ([**] x $5,000,000) + ([**] x $2,000,000) = $[**]

8.6.2           Taxes Related to Employment of Persons.  Contractor accepts full and exclusive liability for the payment of any and all contributions or taxes that are measured by wages, salaries, or other remunerations paid to Persons employed by Contractor (and shall ensure that its Subcontractors do the same) for the Work, or which arise by virtue of their employment, and which now or hereafter are imposed by any Governmental Authority.  Such contributions or taxes include those for unemployment insurance, social security insurance, workers’ compensation, old age retirement benefits and other payroll taxes of any kind.  Contractor shall comply with Applicable Law relating to such subjects and any of such taxes or contributions that Owners may be required by any Governmental Authority to pay shall be chargeable against the Target Price.

8.6.3           Tax and Accounting Information.  Contractor shall provide assistance as reasonably requested by Owners or their tax consultant(s) in confirming eligibility and qualification for exemptions from Sales Taxes to the relevant Governmental Authorities.  From time to time during the term of this Agreement and within thirty (30) Days of a request therefor, Contractor shall provide Owners with information, including regarding quantities, descriptions, costs, amounts of taxes paid and allocations of property acquired in connection with the Work as reasonably requested by Owners in connection with the preparation of tax returns, the defense of tax treatment for such items, for the purpose of satisfying regulatory requirements or as otherwise required in connection with calculating, obtaining exemption from, or rebate of, any Sales Tax or Contractor’s Excise Tax.  Contractor shall assist Owners in taking advantage of any Sales Taxes exemption or other exemption or rebate opportunities identified by Owners, to complete and deliver the applicable documentation in respect thereof.  The benefit of any exemption from or rebate of Sales Taxes or contractor’s excise tax belongs entirely to Owners.

8.8.3       Owners shall pay the Sum of 8.8.1(i) through 8.8.1(iv), or in the event the Sum of 8.8.1(i) through 8.8.1(iv) results in a credit to Owners, such credit will be deducted from Contractor’s Application for Payment for the following month.

8.8.4       The Fixed Portion shall be invoiced based on the percent completion of earned values in the Project Schedule .

8.9          Payment of Substantiated Amount.  Owners shall pay Contractor the amount of each Application For Payment which has been substantiated by Owners, less Retainage and other amounts properly withheld hereunder; provided, however, that if the Total Construction Cost (taking into consideration the latest Application For Payment) is greater that the Target Price, then, with respect to that portion of the Application For Payment that is for amounts in excess of the Target Price, Owners shall only pay to Contractor the Owners’ Share.  Owners shall make such payment within thirty (30) Days after receipt of the complete Application For Payment, subject to the provisions of this Article 8.  If Owners fail to make a payment in respect of an Application For Payment when due or improperly withhold amounts due to Contractor, interest will accrue on such overdue amounts at the Agreed Rate from the date such amount was due to have been paid to and until (but not including) the date it is paid.  Payments made to Contractor in respect of Work performed by Subcontractors constitute trust funds for such Subcontractors and shall not be commingled by Contractor with other funds of Contractor or its Affiliates.

8.12           Final Payment.

8.12.1     Reconciliation.  As a condition of final payment hereunder, Contractor shall have submitted a statement summarizing and reconciling all previous Applications For Payment, payments by Owners, Change Orders, and the Retainage.  Such statement shall calculate the Total Construction Cost (including all amounts incurred by Owners that are chargeable against the Target Price pursuant to this Agreement of which Owners have notified Contractor), Contractor’s Share, and Owners’ Share.  Subject to the provisions of this Agreement, within thirty (30) Days of the receipt of such statement, Owners shall pay Contractor all remaining amounts due, including, if the Total Construction Cost is less than the Target Price, Contractor’s Share of such underage.  If, for any reason, the Total Construction Cost is greater than the Target Price and Owners have paid to Contractor more than Owners’ Share of such overage, Owners shall be entitled to retain from the Retainage an amount equal to such excess payment.  If the Retainage is less than the amount of such excess payment, Contractor shall, on demand, pay to Owners the difference between the Retainage and such excess payment.  Notwithstanding anything to the contrary contained herein, the final payment will not become due and payable until: (i) a Certificate of Final Completion has been executed by Owners; (ii) Owners have received all Subcontractor warranties, Operating and Maintenance Manuals, schematics, Design Documents, As-Built Drawings and such other items as are required by this Agreement; (iii) all Permits or other approvals required of Contractor have been submitted to Owners; and (iv) the conditions of Section 8.12.2 and 8.12.3 have been properly completed.  The making of final payment constitutes a waiver by Contractor of all claims against Owners (and their property) not previously made in writing by Contractor, except that nothing herein may be construed to imply a waiver of any right to any amount which is the subject of a written protest in accordance with Article 23 at the time final payment is made.  Owners shall make final payment to Contractor within thirty (30) Days after the date that all of the preceding matters have been completed or have otherwise occurred.

- 60 -

8.12.2     Release.  As a condition of final payment, Contractor shall submit to Owners a conditional waiver and release upon final payment, in form and substance satisfactory to Owners.  Within five (5) Days after Contractor’s receipt of final payment, Contractor shall deliver to Owners an unconditional waiver and release upon final payment that releases all claims of Contractor under this Agreement and represents that all indebtedness connected with the Work for which Owners or their property might in any way be responsible has been paid, waived, or otherwise satisfied; but if any such indebtedness has not been satisfied, Contractor may satisfy this obligation if it furnishes a bond or other security reasonably satisfactory to Owners to indemnify Owners against any such item of responsibility or obligation.  If any Claim of any kind or nature whatsoever is filed in respect of the Work and such Claim or any Lien arises from or is alleged to arise from any failure of Contractor or any Subcontractor to pay the indebtedness connected with the Work, Contractor shall indemnify, defend and hold Owners harmless for amounts that Owners must pay, in defending or discharging such Claim or Lien, including all costs, reasonable attorneys’ fees, charges and interest.  This provision will survive any expiration or termination of this Agreement.

8.14            Payment of Subcontractors.  Contractor shall promptly pay each Subcontractor when due the amount to which such Subcontractor is entitled.  Contractor shall, by an appropriate agreement with each Subcontractor, require each Subcontractor to make payments to its sub-subcontractors on the same basis.  Owners have no obligation to pay or to see to the payment of any monies to any Subcontractor except as may otherwise be required by Applicable Law, in which event Contractor shall immediately reimburse Owners therefor, with interest thereon at the Agreed Rate.  Upon reasonable prior notice, Owners reserve the right to make payments due hereunder directly to Subcontractors from and after such time as Contractor:  (i) fails to make any payment to a Subcontractor that is properly due or (ii) upon Owners’ request, fails to provide adequate assurances that Contractor’s financial condition is sufficient to continue to pay such amounts as and when they become due without financial risk to Owners.  The amount of any such payment made by Owners directly to Subcontractors shall be credited against the Target Price.

8.16           Overpayment.  Any overpayment by Owners to Contractor shall be deemed to be a mistake of fact and promptly repaid to Owners upon written demand within five (5) Days.

8.17           Tax and Accounting Information.  Contractor shall provide tax and accounting information required by Owners with respect to the Work, including information required for submission to Governmental Authorities.  For accounting purposes, Contractor shall provide to Owners a cost breakdown of the Payment Amount in accordance with the form and systems of accounts provided by Owners.  The sum of the items listed in Contractor’s price breakdown shall equal the Payment Amount.  Overhead and profit shall not be listed as separate items.

ARTICLE 9

EXCUSABLE EVENTS AND FORCE MAJEURE

9.1         Notice.  Contractor will not be held in default or be liable for delay or failure in performing its obligations hereunder to the extent caused by an Excusable Event or event of Force Majeure.  Contractor shall give notice to Owners not more than five (5) Days after it knew or reasonably should have known of the occurrence of such Excusable Event or event of Force Majeure, but in no event later than thirty-five (35) Days after the occurrence of such event.  Such notice will, to the extent practicable, specify the nature of the occurrence and the reasons why Contractor believes additional time, an increase to the Target Price (in the case of an Excusable Event only) or other adjustment to this Agreement should be granted, the length of the delay occasioned by, and unless otherwise provided herein, the additional costs incurred (in the case of an Excusable Event only, which costs shall be in accordance with Section 10.1.2) by reason of such Excusable Event or event of Force Majeure.  Within thirty (30) Days after receipt of such notice, Contractor shall provide to Owners a more detailed statement of the impact of the occurrence, its recovery plan and a detailed estimate of the effect on the Target Price (in the case of an Excusable Event only) and the Project Schedule.  If it is not reasonably possible to provide a full impact analysis (including establishing the basis for and the amount of any adjustment to the Project Schedule or Target Price) within such thirty (30) Day period, Contractor must provide all information reasonably possible as soon as possible after the information is available to Contractor, but no less frequently than weekly.  Contractor will have up to but not exceeding thirty (30) additional Days to supplement its detailed statement in writing; provided, that it continues to advise Owners on a weekly basis.  Any impact not described with particularity within such maximum sixty (60) Day period is waived, unless the Parties agree to an extension of such period.  Strict compliance with this Article 9 is a condition precedent to the establishment of an Excusable Event or event of Force Majeure itself.  Contractor will be entitled to an increase in the Target Price (in the case of an Excusable Event only), an extension of the Project Schedule, or other adjustment to this Agreement, to the extent that such Excusable Event or event of Force Majeure has a material adverse effect on the ability of Contractor to fulfill its obligations under this Agreement, Contractor has taken precautions, due care, and reasonable measures to mitigate the impact of such effects.  Failure by Contractor to give the required notice hereunder of a claim that Contractor knew or should have known will preclude Contractor’s right to invoke the protection of this Article.  The initial notice provided by Contractor must describe in reasonable detail the efforts of Contractor that have been or are going to be made to overcome or remove the Excusable Event or event of Force Majeure and to minimize the potential adverse impact resulting from such Excusable Event or event of Force Majeure.  If within a reasonable time after an Excusable Event or event of Force Majeure has caused Contractor to suspend or delay performance of the Work, Contractor has failed to take such action as Contractor could lawfully and reasonably initiate to remove or relieve either the Excusable Event or event of Force Majeure, or its direct or indirect effects, Owners may, in their sole discretion and after notice to Contractor, initiate such reasonable measures as will be designed to remove or relieve such Excusable Event or event of Force Majeure, or its direct or indirect effects, and thereafter require Contractor to resume full or partial performance of the Work. All costs incurred by Owners shall be chargeable against the Target Price.

 9.2         Rights Limited.  The rights and remedies set forth in this Article 9 constitute Contractor’s sole and exclusive rights and remedies in the event of an occurrence of an Excusable Event or event of Force Majeure, and Contractor hereby waives all other rights and remedies at law and/or in equity that it might otherwise have against Owners on account of an Excusable Event or event of Force Majeure.  For the avoidance of doubt, Contractor will not be entitled to any adjustment of the Target Price as a result of an event of Force Majeure.

10.2           Contractor Change Notice.  If Contractor wishes to make a claim for an adjustment of the Target Price, an adjustment of the Project Schedule, or Change in any other applicable provision under this Agreement (on account of the occurrence of an Excusable Event or event of Force Majeure), Contractor must give notice (“Contractor Change Notice”) in accordance with the time requirements in Article 9.  This Contractor Change Notice must be given by Contractor before proceeding to execute any additional related Work, except in an emergency endangering life or property in which case Contractor may act to prevent threatened damage, injury, or loss.  Contractor shall document and otherwise support any Contractor Change Notice on the same basis and within the thirty (30) and sixty (60) Day periods specified in Article 9.  Owners shall respond to all such Contractor Change Notices within thirty (30) Days after receipt of final documentation from Contractor, setting forth Owners’ position, and, if appropriate, issuing a Change Order or Owners Authorization based thereon.  All Contractor Change Notices must include sufficient documentation for Owners to be able to make a well-informed decision.

18.1           Confidential Information.  The Parties have an interest in maintaining the confidentiality of proprietary information that will be furnished pursuant to this Agreement.  Each Party shall keep in confidence any such information that in good faith is proprietary and which: (i) is specifically designated in writing as being “confidential” or (ii) is disclosed orally, visually or by way of consigned items, and is orally identified as “confidential” at the time of disclosure, which oral identification is confirmed in writing within ten (10) Business Days (“Confidential Information”).  Each Party agrees not to disclose Confidential Information without the prior written permission of the Disclosing Party other than to its directors, officers and employees, agents, contractors, and consultants who reasonably need to have access to such portion of such Confidential Information or use any such information for other than the purpose for which it is supplied, except as provided herein.  Information relating to commercial terms of this Agreement shall also be treated as “Confidential Information;” provided, however, such restriction is intended only to prevent disclosure of the Target Price, Payment Amount, Retainage terms, outage schedules, limits of liability, liquidated damage categories and amounts, warranty provisions, intellectual property provisions, wage rates and unit rates, information obtained by Contractor subject to NERC Requirements, and is not intended to restrict Owners from use of the form of agreement.  Each Party shall be responsible for requiring any third party (excluding such Party’s (or its Affiliates’) officers, directors, employees and counsel who, in each case, will be informed of the requirement to comply with the terms of this Section 18.1, but includingagents, contractors, and consultants who are not officers, directors, or employees of Owners) to whom it wishes to disclose Confidential Information to enter into a confidentiality agreement on reasonable terms and conditions that are customary for confidentiality agreements for similarly situated parties receiving proprietary information comparable to the Confidential Information.  Each Party agrees with respect to Confidential Information, to hold the same confidential for the longer of a period of five (5) years from receipt or for a period of three (3) years from the earlier to occur of termination or Final Completion.  The provisions of this Article 18 shall not apply:

(a) to information which the Receiving Party can substantiate:

(1) was in the possession of the Receiving Party at the time it was initially furnished, without a breach of this provision;

(2) is or becomes part of the public domain without a breach of this provision by the Receiving Party;

(3) is received from a third party who is, to the knowledge of the Receiving Party, under no restriction regarding disclosure;

(4) that the Receiving Party either independently developed or had independently developed for it and was not obtained, in whole or in part, from the Disclosing Party; or

(5) that the Disclosing Party authorized the Receiving Party to disclose.

Such information will not be deemed to be within one of the foregoing exceptions if it is merely embraced by more general information available on a non-confidential basis to the Receiving Party;

- 79 -

(b) to the extent that a Receiving Party is required to disclose information pursuant to Applicable Law, discloses it to the South Dakota Public Utilities Commission or other Governmental Authority, or uses information in connection with any legal proceeding or Dispute under Article 23 hereof; provided, that in such disclosure or use, the Party takes reasonable steps to make the other Party’s Confidential Information subject to any available procedures for maintaining its confidentiality; or

(c) Information that is inappropriately identified as “Confidential” when it is not specifically permitted to be categorized as Confidential Information under this Agreement.

The Parties acknowledge that a violation of provisions of this Section 18.1 by a Party would cause irreparable harm to the Disclosing Party for which no adequate remedy at law exists.  Each Party therefore agrees that, in addition to any other remedies available, the Disclosing Party shall be entitled to seek injunctive relief to enforce the terms of this Section 18.1, including to prevent a breach or contemplated breach hereof, without, in any case, proof of actual damages or the posting of any bond or security, which posting is hereby waived to the fullest extent permitted by Applicable Law.

18.2           Import or Export of Technical Data.  Contractor agrees to comply with Applicable Law regarding the import or export of technical data or information or any product based thereon and shall not ship or communicate or allow to be shipped or communicated, either directly or indirectly, any technical data or information or any product based thereon in connection with the Work to any country or from any country to or from which such shipment or communication is prohibited by Applicable Law.

18.3           Third Party Proprietary Information.  Contractor also agrees to enter into confidentiality agreements with third parties at Owners’ request and to keep in force confidentiality agreements concerning third parties’ proprietary information, which agreements shall permit Contractor to use such parties’ proprietary information solely in connection with the Work.  Such agreements are to be consistent with current industry practices and will not contain provisions that preclude Contractor’s participation in other projects or work.

18.4           Public Relations.  Contractor agrees that all public relations matters arising out of or in connection with the Work will be the sole responsibility of Owners. Contractor shall obtain Owners’ prior written approval of the text of any announcements, publications, photographs, or other type of communication concerning the Work which Contractor or its Subcontractors wish to release for publication, which approval may be withheld in Owners’ sole discretion.

24.1.2      Assumption.  Notwithstanding anything to the contrary herein, Owners, in lieu of the payment of any cancellation charge pursuant to Section 24.1.1, may, upon request, assume all of Contractor’s obligations under any purchase order or other agreement with a Subcontractor.  Contractor, upon Owners’ request, shall promptly provide Owners with: (i) a copy of any purchase order or other agreement with a Subcontractor and (ii) an estoppel certificate stating all known unsatisfied Liabilities under any such purchase order or other agreement.  Thereafter, upon Owners’ request, Contractor shall assign all of its right, title and interest in any such purchase order or other agreement with a Subcontractor to Owners.  Such assignments shall be in form and substance satisfactory to, and at no additional cost to, Owners.  Such agreements shall be in full force and effect upon such assignment.  Contractor covenants that a provision substantially similar to this Section 24.1.2 shall be inserted in each such agreement with a Subcontractor to preserve the rights of Owners under this Section 24.1.2.

24.1.3      Mitigation.  If any cancellation payment is due to Contractor from Owners, Contractor shall use its reasonable best efforts to minimize the amount of such cancellation payment.

24.2        Termination by Owners for Cause.

24.2.1      Default by Contractor.  The occurrence of any one or more of the following, and, with respect to clauses (ii), (iv), (vi) or (vii), the continuation of the same for thirty (30) Days after Contractor’s receipt of written notice thereof from Owners, will constitute a default by Contractor under this Agreement (a “Contractor Default”); provided, that with respect to clauses (ii), (iv), (vi) or (vii), if such Contractor Default cannot reasonably be cured within such thirty (30) Day period, such cure period shall extend for a total of ninety (90) Days, so long as Contractor diligently pursues a cure throughout such period:

(i) Contractor experiences an Insolvency Event;

(ii) the material breach of any representation or warranty made by Contractor herein;

- 91 -

(iii) Contractor attempts to assign, convey or transfer this Agreement or any interest or right herein without Owners’ prior written consent, except as otherwise permitted by this Agreement;

(iv) Contractor fails to materially observe or perform any other covenant, agreement, obligation, duty or provision of this Agreement;

(v) the interest of Contractor passes to any Person otherwise than as permitted herein;

(vi) Contractor fails to make prompt payment to Subcontractors of amounts due for labor, Contractor Supplied Materials and Equipment, Consumables, or Construction Aids, or disregards laws or ordinances or the lawful requirements of any competent authority or the instructions of Owners consistent with this Agreement;

(vii) Contractor fails, neglects, refuses or is unable at any time during the course of the Work, except in the event of an Excusable Event or event of Force Majeure, to provide ample Contractor Supplied Materials and Equipment, Consumables, or Construction Aids, or labor to perform Work in accordance with the Project Schedule or to provide a recovery plan to satisfaction of Owners;

(viii) Contractor fails to comply with Article 21 or the Payment and Performance Bonds, for any reason, ceases to be valid or enforceable in any way;

(ix) Contractor fails to achieve Mechanical Completion within ninety (90) Days of the Guaranteed Mechanical Completion Date;

(x) Contractor fails to achieve Substantial Completion within thirty (30) Days of the Guaranteed Substantial Completion Date; or

(xi) Contractor fails to achieve Final Completion within thirty (30) Days of the Guaranteed Final Completion Date.

- 92 -

24.2.2      Owners’ Remedies.  Upon the occurrence of a Contractor Default, Owners may, without prejudice to any other right or remedy Owners may have under this Agreement: (i) terminate this Agreement; (ii) take possession of (a) the Job Site and of all Contractor Supplied Materials and Equipment and Consumables, (b) Construction Aids, tools and machinery on the Big Stone Site, and (c) Information; (iii) finish the Work by whatever method Owners may deem expedient; and (iv) draw on the Retainage or withhold amounts due to Contractor to make payments for the actual costs therefor.  If the unpaid balance of the Target Price exceeds the cost of finishing the Work, then Contractor will be paid for (i) the Cost Reimbursable Portion incurred and not previously paid plus (ii) the Fixed Portion earned as of the date of termination but not previously paid (such sums in clauses (i) and (ii) the “Unpaid Amount”).  However, if the cost of finishing the Work (including the cost of arranging for completion of the Work and performing such Work on an accelerated basis to preserve as nearly as possible adherence to the Project Schedule) and performing Contractor’s other obligations under this Agreement exceeds the unpaid balance of the Target Price, then (i) if the Unpaid Amount exceeds Contractor’s share of the excess of the Total Cost over the Target Price, such share determined pursuant to Section 8.5, Contractor shall be paid the difference between the Unpaid Amount and such share of such excess, or (ii) if the Unpaid Amount is less than Contractor’s share of the excess of the Total Cost over the Target Price, such share determined pursuant to Section 8.5, Contractor shall immediately pay to Owners the difference between Contractor’s share of such excess and the Unpaid Amount.  Owners will be entitled to withhold further payments to Contractor until the Work has been completed and a determination that Contractor is entitled to further payments.  Any amounts not paid hereunder when due will bear interest at the Agreed Rate.  Owners may in their discretion employ such other Persons to finish the Work by whatever method or means as Owners in their sole discretion may deem reasonably expeditious; provided, that the balance of Work and obligations will be completed utilizing reasonable methods of construction management and construction consistent with the Project Schedule, as adjusted.  If this Agreement is terminated pursuant to this Section 24.2.2 and is later determined that no Contractor Default had occurred, such termination shall be deemed to be a termination pursuant to Section 24.1.1.

24.3        Termination by Contractor for Cause.

24.3.1      Default by Owners.  The occurrence of any one of more of the following matters, and, with respect to clauses (ii) or (iii), the continuation of the same for thirty (30) Days after Owners’ receipt of written notice thereof from Contractor, will constitute a default by Owners under this Agreement (an “Owners Default”); provided that with respect to clauses (ii) or (iii), if such Owners Default cannot reasonably be cured within such thirty (30) Day period, such cure period shall extend for a total of ninety (90) Days, so long as Owners diligently pursue a cure throughout such period:

(i) Owners experience an Insolvency Event.

(ii) the breach of any material representation or warranty made by Owners herein;

(iii) Owners fail to make payment to Contractor of any undisputed amount when due which failure continues for thirty (30) days after written notice from Contractor of such non-payment.

24.3.2      Contractor’s Remedies.  Upon the occurrence of an Owners Default, but subject to Section 23.2, Contractor may suspend its performance of the Work (for a maximum of fifteen (15) Days in the aggregate) or terminate this Agreement.  If this Agreement is so terminated by Contractor for an Owners Default, Contractor, as its sole and exclusive remedy hereunder, shall be entitled to receive an amount calculated in accordance with Section 24.1.1.

- 93 -

24.4        Suspension of the Work.  Owners may, without cause, order Contractor to suspend the Work or extend the Project Schedule in whole or in part for such period of time as Owners may determine.  Any such suspension or extension will commence as soon as reasonably possible, but no later than the second (2nd) Day after Contractor’s receipt of written notice thereof from Owners.  Such suspension or extension shall continue for the period specified in Owners’ notice to Contractor.  Contractor will resume any suspended Work within three (3) Days of Owners’ written notice directing the same.  Without limiting Owners’ rights under Section 24.1, should a suspension of the entire Work which is ordered by Owners pursuant to this Section 24.4 (but excluding any suspension caused by a Force Majeure) continue for three hundred sixty (360) or more consecutive Days, either Party may thereafter terminate this Agreement by written notice to the other Party and the rights and remedies of Contractor will be the same as those which are expressed in Section 24.1.1 hereof in the event of termination for convenience by Owners.  In the case of any suspension of the entire Work under this Section 24.4, except to the extent an acceleration of the Work is authorized by Owners (such acceleration being subject to a Contractor Change Notice as applicable), the Project Schedule will be extended by a period equal to the suspension period, and adjusted by Owners, in consultation with Contractor, to account for same.  In the case of any suspension or extension of a portion of the Work under this Section 24.4, the Project Schedule shall be extended only to the extent the suspension or extension can be shown on the Project Schedule to affect the critical path. This will be based on the most current Project Schedule in effect on the Day of suspension and take into account the critical path for completing the entire Work and the non-critical path activities suspended or extended.  Owners shall pay Contractor in accordance with the terms of payment set forth in this Agreement for the Work completed prior to the time of any suspension and for the direct reasonable costs that result from Contractor’s compliance with the suspension notice, including reasonable costs of demobilization, remobilization and standby costs, if applicable.  Owners shall pay Contractor the direct reasonable costs associated with the restart of suspended Work under this Section 24.4 and shall resume payments to Contractor in accordance with the terms of payment under this Agreement thirty (30) Days after the restart of the Work and such amounts shall not be charged against the Target Price.  It is a precondition to all claims by Contractor for extension or compensation under this Section 24.4, that the same be made within thirty (30) Days after the suspension period has ended, or said claim is barred.

ARTICLE 25

25.6        Incorporation by Reference.  The recitals set forth on the first page of this Agreement are hereby incorporated into this Agreement by this reference and expressly made a part of this Agreement.

25.7        No Waiver.  No course of dealing or failure of Owners or Contractor to enforce strictly any term, right or condition of this Agreement may be construed as a waiver of such term, right or condition.  No express waiver of any term, right or condition of this Agreement will operate as a waiver of any other term, right or condition.

25.8        Agreed Rate.  Unpaid amounts will bear interest at an annual (365 or 366 Days, as appropriate) rate equal to the lesser of: (i) two percent (2%) in excess of the Prime Rate and (ii) the maximum rate permitted by Applicable Law (the “Agreed Rate”).

25.9        Audit.

25.9.1      Access to Records.  Contractor (and its Subcontractors as applicable) shall maintain: (i) the Estimate; (ii) complete and accurate financial books and records to allow compliance with Sections 8.6, Section 20.4, or which relate to any cost-based (i.e., Work not covered by lump-sum prices), components of the Work billed under this Agreement or relating to the quantity of units billed under any unit pricing agreed to by the Parties and amounts in respect of a payment made pursuant to Section 24.1; and (iii) complete and accurate books and records relating to Contractor’s obligations with respect Hazardous Substances, health and safety, environmental management, emergency response, testing and inspection of Contractor Supplied Materials and Equipment, quality control (including non-conformance reports), NERC Requirements, and the requirements of Section 25.20 (all the foregoing hereinafter referred to as “Records”) for a minimum of five (5) years following Final Completion.  All such Records must be open to inspection and subject to audit and reproduction during normal working hours by Owners or their respective authorized representatives to the extent necessary to adequately permit evaluation and verification of any invoices, payments, time sheets, or claims based on Contractor’s actual costs incurred in the performance or delivery of Work under this Agreement.  For the purpose of evaluating or verifying such actual or claimed costs, Owners and their respective authorized representatives will have access to Records at any time, including any time after final payment by Owners to Contractor pursuant to this Agreement.  Owners and their respective authorized representatives shall have access, during normal working hours, to all necessary Contractor facilities.  Contractor shall provide adequate and appropriate work space to conduct audits pursuant to this Section 25.9.1.  Owners shall give Contractor reasonable notice of the date and time they, any individual Owner or any agent of either of them intend to commence any audit.  If the audit should disclose an overbilling, Contractor will pay Owners’ invoice rectifying such overbilling within thirty (30) Days of receipt.  The rights of Owners set forth in this Section 25.9.1 shall survive the termination or expiration of this Agreement.

- 96 -

25.9.2      Unit Prices.  When Contractor’s invoice includes compensation for Work performed on unit price basis, Contractor shall submit Contractor’s determination of units of Work performed determined in accordance with the provisions of this Agreement, and substantiated by applicable Records.  Upon verification by Owners of such Records, Owners will advise Contractor in writing of either Owners’ acceptance of Contractor’s determination of units or Owners’ determination of such units.  If Contractor believes that Owners have incorrectly determined the units of Work performed, Contractor will comply with the provisions of Article 23.  All undisputed amounts will be due and payable in accordance with this Agreement.

25.9.3      Time and Materials.  When Contractor’s Application for Payment includes compensation for Work performed on a time and material basis or similar basis of compensation, Contractor shall submit to Owners a detailed breakdown in a form reasonably acceptable to Owners of the costs of labor, Contractor Supplied Materials and Equipment, Consumables, Construction Aids, and markups or fees (if any) due for such month to Contractor.  All costs reflected in such breakdown shall be net of applicable credits.  The term “Applicable Credits” means any and all refunds, rebates, credits, discounts, or similar amounts (including any interest thereon) received by Contractor or to which Contractor is or will be entitled in connection with its performance of the Work.  Contractor shall pay, and require each of its Subcontractors to pay, all invoices received in connection with performance of the Work as required by the terms of their respective contracts. Upon receipt of such breakdown, Owners shall make the determination of the amount due Contractor, and unit prices (if applicable) shall govern.  The determination of Owners shall be final and conclusive, subject to Contractor’s right to dispute such determination pursuant to Article 23.  Each invoice shall be accompanied with partial releases of Liens in form substantially in the form of Exhibit F-5.

25.9.4      Audit Limits.  Owners’ right to audit under this Section 25.9 does not include the right to audit the make-up or components of any agreed multipliers, rates, mark-ups, or fixed percentages, but does include the right to audit the application of such multipliers, rates, mark-ups, or fixed percentages.  In connection with Work priced on a lump-sum basis, Contractor’s published price lists, unit rates, markups and multipliers which have been agreed upon and specified herein are not subject to audit; provided, however, the determination of costs for all purposes under this Agreement shall be on an open-book basis.

- 97 -

25.10     Survival.  Articles 7, 13, 16, 17, 18, 19, 20, 21 (and Exhibit I), 23 and 25 and Sections 4.38, 8.12.2, and 22.2 of this Agreement and all other Articles and Sections thereunder providing for indemnification, or limitation of or protection against liability of either Party, survives the termination, cancellation or expiration of this Agreement.

25.11     No Third Party Beneficiaries.  The provisions of this Agreement are intended for the sole benefit of Owners and Contractor and, except to the extent specifically identified herein, there are no third party beneficiaries other than assignees contemplated by the terms herein.

25.12     Non-Recourse.  Anything to the contrary notwithstanding, the obligations of Owners under this Agreement (i) are individual and special obligations of Owners and do not constitute obligations of (and no recourse shall be had with respect thereto to) any shareholder of Owners, any of their Affiliates, or any shareholder, partner, member, officer, director, commissioner or employee of any such Person and (ii) no action shall be brought or maintained against any such partner, Affiliate companies, or any shareholder, partner, member, officer, director, commissioner or employee of any thereof.  The Parties acknowledge and agree that any provision of this Agreement that limits, excludes or protects against any liability of Owners, grants indemnity or confers rights or remedies that are intended to benefit (and be enforceable by) Owners, shall be applicable to Owners whether or not Owners are specifically referenced in such provision.

25.13     Contractor’s Security.  Owners’ obligation to make any payment to Contractor hereunder is subject to the receipt of the Payment and Performance Bonds.  Prior to, or simultaneous with, the issuance by Owners of the Notice to Proceed, Contractor shall deliver to Owners an assurance of completion in the form of separate performance and payment bonds, each with a penal sum equal to the Target Price, in form and substance acceptable to Owners (the “Payment and Performance Bonds”).  The Payment and PerformanceBonds must be obtained from guaranty or surety companies acceptable to the U.S. Government and authorized to do business in the State of South Dakota.  Individual sureties will not be considered. U .S. Treasury Circular Number 570, published annually in the Federal Register, lists companies approved to act as sureties on bonds securing United States government contracts, the maximum underwriting limits on each contract bonded, and the States in which the company is licensed to do business. Use of companies listed in this circular is mandatory. Copies of the circular may be downloaded on the U.S. Department of Treasury website http://www.fms.treas.gov/c570/index.html, or ordered for a minimum fee by contacting the Government Printing Office at (202) 512-2168.

25.14     Provisions Required by Law.  Any term or condition required to be contained in this Agreement as a matter of Applicable Law that is not so contained herein is deemed to be incorporated in this Agreement as though originally set forth herein.

25.15     Severability.  If any provision of this Agreement, or the application thereof to any Person or circumstance, is to any extent held invalid or unenforceable by a court of competent jurisdiction or pursuant to arbitration as provided herein, the remainder of this Agreement, and the application of such provision to Persons or circumstances other than those as to which it is specifically held invalid or unenforceable, will not be affected thereby, and each and every remaining provision of this Agreement will be valid and binding to the fullest extent permitted by Applicable Law; provided, however, the Parties agree to negotiate in good faith and shall reform this Agreement to as closely as possible resemble the original intent and allocation of risks and benefits.

- 98 -

25.16     Joint Effort.  Preparation of this Agreement has been a joint effort of the Parties and the resulting document (or any portion) is not to be construed more severely against one of the Parties than against the other.

25.17     Counterparts.  This Agreement may be executed in two (2) or more counterparts, each of which is deemed to be an original, but all of which together shall constitute one and the same instrument.

25.18     Approvals Not To Relieve Contractor.  No approval, consent or failure to disapprove, inspect or failure to inspect, or comment on, any matter by or the submission of any drawing or document to, or acquiescence on the part of, Owners, including any Turnover Acknowledgment, will relieve Contractor of any liability for any of its obligations under this Agreement or otherwise.

25.19     Consultants.  At their option, Owners may retain the services of others, including engineers and financial consultants, to assist Owners in monitoring the conduct of the Work by Contractor.  All rights of access and protection, including Contractor’s obligation to indemnify, defend and hold harmless Owners, will be afforded equally to any of their agents and consultants.

25.20     Equal Employment Opportunity.  To the extent applicable, Contractor shall comply with all of the following provisions, which are incorporated herein by reference: (i) Equal Opportunity regulations set forth in 41 CFR § 60-1.4(a) and (c), prohibiting employment discrimination against any employee or applicant because of race, color, religion, sex, or national origin; (ii) Vietnam Era Veterans Readjustment Assistance Act regulations set forth in 41 CFR § 60-250.4 relating to the employment and advancement of disabled veterans and Vietnam era veterans; (iii) Rehabilitation Act regulations set forth in 41 CFR §60-741.4 relating to the employment and advancement of qualified disabled employees and applicants for employment; (iv) the clause known as “Utilization of Small Business Concerns and Small Business Concerns Owned and Controlled by Socially and Economically Disadvantaged Individuals” set forth in 15 USC § 637(d)(3); and (v) the subcontracting plan requirement set forth in 15 USC § 637(d).

Storm Water Pollution prevention
Plan

1.0 Person(s) responsible for implementation of the plan

The following person(s) will be responsible for implementing and maintaining the Storm Water Pollution Prevention Plan:

Contractor shall be responsible for properly installing and maintaining BMPs as specified in the SWPPP. Otter Tail Power Company employee Kirk Phinney or other OTP employee as delegated by Kirk shall be responsible for site SWPPP inspections and shall notify Contractor of any deficiencies in BMPs found during inspections. Any deficiencies in BMPs shall be fixed by Contractor as soon as possible but no later than 7 days after deficiency is discovered. OTP and Contractor are responsible for maintaining and updating their respective copy of the SWPPP.

2.0 Description of the project and the type of construction activity

Otter Tail Power Company is required to install Air Quality Control System (AQCS) equipment at its Big Stone Plant, located near Big Stone, Grant County, South Dakota, to reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOX) based on a Best Available Retrofit Technology (BART) determination filed by the South Dakota Department of Environment and Natural Resources (DENR). The BART requires the AQCS system to include flue gas desulfurization (FGD) for SO2 reduction, and selective catalytic reduction (SCR) with separated overfire air (SOFA) for NOX reduction. The AQCS retrofit proposed comprises a dry FGD system with new baghouse, SOFA, anhydrous-based SCR, activated carbon injection (ACI), and the associated ancillary balance-of-plant systems.

To support the construction of these systems, the site will be developed to include laydown areas, contractor parking, truck staging, new process equipment buildings, topsoil storage, and borrow areas. A site map showing areas to be developed as well as erosion and sediment control devices to be installed can be seen in Exhibit A. Contractor will be made aware of site boundaries prior to land disturbing activities.

The laydown area elevation varies from approximately 1094 ft to 1111 ft, the contractor parking from approximately 1113 ft to 1120 ft, the truck staging area from approximately 1094 ft to 1113 ft, and the topsoil storage area from approximately 1100 ft to 1106 ft. All elevations provided are in the North American Vertical Datum of 1988 (NAVD88). Each area will be graded to allow for its intended purpose while maintaining positive drainage. Each laydown and parking area will be surfaced with crushed aggregate. The topsoil and stockpile area will be seeded for the duration of the construction period. Excavations will be made for the installation of footings and building foundations. Buildings will be erected to provide housing for new process equipment. At the writing of this SWPPP the precise elevations for building foundations are yet to be determined.

Drainage

To facilitate proper drainage of each area of development, a storm water drainage system will be installed consisting of open ditches, swales, and culverts. In addition, a sediment pond and sediment trap will be installed in the main laydown and truck staging areas respectively. Storm water from the borrow area drains to a ditch to the east. This ditch then drains south and discharges offsite.

Big Stone Plant
Storm Water Pollution prevention
Plan

Storm water runoff from the contractor parking, switchyard, topsoil stockpile, the east portion of the staging area, and main site laydown areas will drain to the sediment pond on the south portion of the site and drain offsite. The sediment pond will have a riser with orifice holes to control storm water discharge. The truck staging area will drain to a sediment trap before being discharged offsite to the south. Storm water discharge from the sediment trap will be controlled by a riser with orifice holes, similar to the sediment pond. Finally, the west portion of the staging area drains to the existing west sludge pond. No storm sewers or storm drain inlets exist on or near the site.

Erosion Control

Erosion on the site will be controlled by a number of methods. Site surfacing such as crushed aggregate, temporary seeding, and erosion control blankets, will help prevent erosion by absorbing the energy of raindrops impacting the surface thus retaining soil particles and other pollutants in place. The site surfacing will also help to hold any soil in place that does become dislodged during a storm event. In addition, erosion control devices, such as silt fence and straw bales, will be installed to reduce the amount of erosion during a storm event. These devices slow the velocity of water by interrupting the flow and helping to maintain sheet flow. Concentrated flows generate more energy and velocity than sheet flow and a greater depth of flow and higher velocity results in more erosion and suspension of eroded materials within the flow. By reducing the flow velocity erosion will be reduced.

Sediment Control

Sediment from the site will also be controlled by a number of methods. The sediment pond being installed will hold runoff for an extended period of time, allowing solids to settle to the bottom of the pond. In addition, a number of filtration devices, such as silt fence and straw bales will be used on the site. These filtration devices work by slowing the flow of water as it passes thru the device and suspending material within the filter medium. Haul trucks will be loaded properly to prevent material from falling or spilling out of the vehicles.

3.0 Description of potential pollutant sources and exposed materials

Potential pollutant sources to storm water runoff may occur from the following activities:

● Clearing and grubbing

● Grading and earthwork

● Paving operations

● Site demolition

5.0 Estimate of the total disturbed area of the site

The total site area of the Big Stone Plant, excluding the cooling and evaporation ponds and landfill area, is approximately 250 acres. Of this area, a total of approximately 48 acres will be developed for laydown associated with site development. This total is a summation of the following individual areas:

● Main site laydown area (Area 1) = 28.63 acres

● Topsoil stockpile area (Area 2) = 3.65 acres

● Truck staging area (Area 3) = 3.48 acres

● Main contractor parking area (Area 4) = 4.67 acres

● Parking area west of switchyard (Area 5) = 1.95 acres

● Abandoned sludge pond/staging area (Area 6) = 4.20 acres

● Site borrow area (Area 7) = 3.19 acres

6.0 Description of the intended sequence of soil disturbing activities

The sequence of construction activities shall be as follows:

● Install perimeter erosion and sediment control devices

● Install silt fence around soil stockpile area, construction laydown areas, contractor parking area, and truck staging area

● Clear and grub site

● Install swales and drainage ditches with straw bales

● Strip topsoil from all areas to be disturbed and stockpile in designated area. Install temporary seeding on stockpile

● Complete all earthwork activities, including installation of sediment pond. Install remaining temporary and permanent sediment erosion control devices

● Grade site and install surfacing on all disturbed areas

● Complete all construction related to retrofit project. Remove all temporary erosion and sediment control measures within 30 days of final site stabilization

Construction shall be sequenced to allow for grading activities to begin and end as quickly as possible to prevent lengthy periods of exposed soil. Construction shall also be sequenced to account for winter months when there will be no construction activity.

7.0 Description of the soil type within the disturbed areas

The subsurface generally consists of lean clay with significant seams of silt and sand with occasional cobbles and boulders. Cohesive soil samples generally appeared to be stiff to very stiff, with local medium stiff or hard deposits. Granular soil samples generally appeared to be medium dense to dense, with local loose or very dense deposits.

It does not appear possible to differentiate individual sand seams and it is likely that they are not continuous laterally throughout the project area. Note that many of the cohesive soil samples were sandy and that many of the granular soil samples contained significant fines. While the USCS soil classification system differentiates soils between sands and gravels from silts and clays on the basis of fines content, many of the soils may behave in a manner that shares characteristics of both granular and cohesive soils.

8.0 Name of the surface water(s) that may receive discharges from the site

Storm water runoff from all areas of the site to be developed will be drained through swales, ditches, and culverts prior to discharging offsite. All storm water runoff associated with site development of the laydown areas overland flows south and discharges into the Whetstone River, a tributary to the Minnesota River.

In addition to the storm water runoff that discharges offsite, a portion of the runoff associated with installation of the AQCS retrofit will be contained onsite. The retrofit area drains to the existing plant sluice outfall. Water from the sluice outfall is then pumped to the cooling pond and reused by the plant. As a result, there will be no offsite storm water discharge from the future retrofit area work.

9.0 Equipment Fueling and Maintenance

Equipment will be fueled by a fuel truck. All fueling operations will be supervised to prevent spills and overflows. Vehicles will be stored or level ground to the extent possible to reduce the potential for leaks to run off site and shall be checked for leaks on a regular basis. Avoid washing down or fueling equipment near waterbodies.

10.0     Inspections

All areas of the construction site will be inspected by an OTP employee including: stabilized areas, BMPs, haul roads, equipment storage areas, and disturbed areas.

Records of inspections shall be kept on site for the duration of the construction project and be available for review. Copies of all inspections shall be retained by the Environmental Services Department. Inspection and maintenance must be recorded in writing.

1.0	DEFINITIONS
	“ARSD” means the Administrative Rules of South Dakota.
	“Best Management Practices” (“BMPs”) means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants to waters of the state. BMPs also include treatment requirements, operating procedures, and practices to control construction site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
	“Commencement of Construction Activities” means the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction-related activities (e.g., stockpiling of fill material).
	“Concrete Washout” as used in the General Permit refers to any wash waters derived from the cleaning of concrete trucks and/or equipment.
	“Control Measures” as used in this General Permit, refers to any Best Management Practice or other method used to minimize erosion and sedimentation, and thereby minimize the discharge of pollutants to waters of the state.
	“DENR” means the South Dakota Department of Environment and Natural Resources.
	“Discharge” as used in the General Permit is as an addition of any pollutant or combination of pollutants to surface waters of the state from any point source. Construction sites disturbing one or more acres are point sources. Therefore, any water flowing off the construction site constitutes a discharge and must be covered by a Surface Water Discharge permit.
	“Final Stabilization” means one of the following:
		1.	All soil disturbing activities at the site have been completed and a uniform perennial vegetative cover with a density of 70% of the native cover for unpaved areas and areas not covered by permanent structures has been established, or equivalent permanent stabilization measures (such as the use of gravel, riprap, gabions, or geotextiles) have been employed; or
		2.	When background native vegetation will cover less than 100 percent of the ground (e.g., arid areas, beaches), the 70 percent coverage criteria is adjusted as follows: if the native vegetation covers 50 percent of the ground, 70 percent of 50 percent (0.70 X 0.50 = 0.35) would require 35 percent total cover for final stabilization. On sites with no natural vegetation, no vegetative stabilization is required.
		3.	For construction projects on land used for agricultural purposes, final stabilization may be accomplished by returning the disturbed land to its pre-construction agricultural use. Areas disturbed that were not previously used for agricultural  activities, such as buffer strips immediately adjacent to “waters of the state,” and areas that are not being returned to their pre-construction agricultural use shall meet the final stabilization criteria in (1) or (2) above.

	3.	All permittees shall submit a NOT within thirty (30) days after final stabilization has been achieved.
	4.	The General Permit allows for co-permittees on a site. However, if a permittee has transferred coverage to a new owner and no longer has responsibility for any portion of the site, a NOT shall be submitted by the previous owner terminating coverage under the General Permit.

7

3.0	EFFLUENT LIMITS
	Effective immediately and lasting through the life of the General Permit, all permittees shall comply with the effluent limits below. All permittees are expected to meet the following effluent limits to minimize the pollutants present in the discharges associated with construction activity.
	3.1	Precipitation Design Event
		All sediment and erosion controls shall be selected, designed, and installed to minimize the pollutants present in runoff from a rainfall event of up to two (2) inches in a 24-hour period.
	3.2	Sediment Controls
		The permittee is required to implement sediment controls based on the amount of land disturbed by the project. The sediment control requirements are as follows:
		1.	For drainage locations serving less than 10 disturbed acres at one time, sediment basins and/or sediment traps shall be used. At a minimum, silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries (and for those side slope boundaries deemed appropriate as dictated by individual site conditions) of the construction area.
		2.	For common drainage locations that serve an area with 10 or more acres disturbed at one time, a temporary or permanent sediment basin shall be provided. This basin shall provide storage for a calculated volume of runoff from the disturbed drainage area from a 2-inch precipitation event in a 24-hour period.
		3.	Where it is not possible to construct a temporary sediment basin for drainage locations that serve 10 or more disturbed acres at one time, smaller sediment basins and/or sediment traps or equivalent controls shall be used. At a minimum, equivalent sediment controls are required for all down slope boundaries (and for those side slope boundaries deemed appropriate as dictated by individual site conditions).
			The permittee shall document in the SWPPP its rationale for using alternative sediment controls instead of a sediment basin. This rationale will be reviewed during inspections of the construction site.
	3.3	Maintenance of Sediment Controls
		The permittee shall maintain all sediment controls in effective working order. If any controls are not operating effectively, the permittee shall perform maintenance on the controls as necessary to maintain the continued effectiveness of the storm water controls and before the next anticipated storm event or within seven (7) days of identifying the need for maintenance, whichever comes first.

8

1. The erosion and sediment controls required for compliance with the effluent limits shall be maintained from the beginning of the construction activity until final stabilization is complete. At a minimum, the permittee shall:

	a.	Remove sediment from sedimentation ponds when design capacity has been reduced by 50% or more.
	b.	Remove sediment from silt fences and other sediment controls before the deposit reaches 50% the above-ground height.
2.	All erosion and sediment control measures and other protective measures identified in the SWPPP shall be maintained in effective operating condition. If the site inspections required by Section 3.12 identify BMPs that are not operating effectively, maintenance shall be performed as stated above.

3.4	Off-Site Sediment Tracking and Dust Control
	The permittee shall minimize dust generation and vehicular tracking of soil off-site. At a minimum, street sweeping shall be performed if other best management practices are not adequate to minimize sediment from being tracked on to the street.
3.5	Off-Site Accumulations
	1.	If sediment escapes the construction site, the permittee shall remove the off-site accumulations of sediment at a frequency sufficient to minimize impacts.
	2.	The permittee shall revise the SWPPP and implement controls to minimize further off-site sedimentation.
3.6	Inlet Protection
	All storm drain inlets that receive storm water flows from the construction site shall be protected with appropriate best management practices during construction to minimize the discharge of pollutants from the site. The inlet protection shall be maintained until all sources with the potential for discharging to the inlet have reached final stabilization.
3.7	Erosive Velocity Control
	The permittee shall place velocity dissipation devices at discharge points and along the length of a runoff conveyance, as necessary, to provide a non-erosive flow and protect the receiving water body’s natural, pre-construction uses and characteristics, both physical and biological.
3.8	Soil Stockpiles
	Temporary soil stockpiles shall have silt fence or other effective controls to minimize sediment runoff, at a minimum. Soil stockpiles shall not be placed in surface waters, including storm water conveyances such as curb and gutter systems, or conduits and ditches, or where likely to be disturbed during storm events.
3.9	Erosion Control and Stabilization
	The permittee shall stabilize disturbed portions of the site as soon as possible with appropriate BMPs, but in no case more than 14 days after construction activity has temporarily or permanently ceased on any portion of the site. An exception to this effluent limit is allowed if earth-disturbing activities will be resumed within 21 days. All other exceptions shall be approved on an individual basis by the Secretary.

9

3.10	Construction and Waste Materials
	The permittee shall properly handle, store, and dispose of litter, construction debris, construction chemicals, and concrete washout to minimize pollutants entering storm water discharges. Permittees are required to minimize the discharge of solid materials to waters of the state (except where authorized by a Section 404 permit from the United States Army Corps of Engineers).
3.11	Spills / Releases in Excess of Reportable Quantities
	1.	The permittee shall have the capacity to control, contain, and remove spills at the site. If spills do occur, the permittee shall modify the SWPPP and implement controls to minimize the potential for contamination of the storm water.
	2.	Spills in excess of reportable quantities shall be properly reported as stated in Section 5.1.
3.12	Site Inspections
	1.	An inspection of the site shall be conducted at least once every seven (7) calendar days and within 24 hours of the end of storm that is 0.5 inches or greater, or a snowmelt event that causes surface erosion. Once a site has been temporarily stabilized and construction has ceased for the winter, such inspections shall be conducted at least once per month.
	2.	The inspections shall be conducted by personnel who are familiar with the General Permit conditions and with the proper installation and operation of storm water controls.
	3.	The inspection shall include disturbed areas of the construction site that have not been finally stabilized, areas used for storage of materials, structural control measures, and locations where vehicles enter or exit the site. These areas shall be inspected for evidence of, or the potential for, pollutants entering the drainage system, and erosion and sediment control measures identified in the SWPPP shall be observed to ensure that they are operating correctly and sediment is not tracked off-site.
	4.	The permittee shall maintain records of each inspection and resulting maintenance activities, including:

a.	Date and time of inspections;
b.	Name(s) and title(s) of personnel conducting the inspections;
c.	Findings of inspections;
d.	Corrective actions taken;
e.	Dates and amount of all rainfall events greater than 0.5 inches in 24 hours; and
f.	Documentation of any changes made to the SWPPP.

10

	Where an inspection does not identify any incidents of non-compliance, the report shall contain a certification that the site is in compliance with the SWPPP and this General Permit. The report shall be signed in accordance with the signatory requirements in Section 6.9.
5.	The SWPPP shall be revised if the site inspections identify any non-compliance with the effluent limits. The changes shall be implemented at the site within seven (7) calendar days following the inspection.

11

6.14	Proper Operation and Maintenance
	The permittee shall at all times properly operate and maintain all systems of treatment and controls that are used to achieve compliance with the conditions of this General Permit. Proper operation and maintenance requires the operation of backup or auxiliary facilities or similar systems, installed by the permittee, only when necessary to achieve compliance with the conditions of the General Permit.

20

CERTIFICATION OF APPLICANT (COA)

I, ______________________ , the applicant(s) in the above matter after being duly sworn upon oath hereby certify the following information in regard to this application:

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including revocation of the permit and the possibility of fine and imprisonment for knowing violations. In addition, I certify that I am aware of the terms and conditions of the General Storm Water permit and I agree to comply with those requirements.

South Dakota Codified Laws Section 1-40-27 provides:

“The secretary may reject an application for any permit filed pursuant to Titles 34A or 45, including any application by any concentrated swine feeding operation for authorization to operate under a general permit, upon making a specific finding that:

(1) The applicant is unsuited or unqualified to perform the obligations of a permit holder based upon a finding that the applicant, any officer, director, partner or resident general manager of the facility for which application has been made:

(a)	Has intentionally misrepresented a material fact in applying  for or a permit;
(b)	Has been convicted of a felony or other crime involving moral turpitude;
(c)	Has habitually and intentionally violated environmental laws of any state or the United States which have caused significant and material environmental damage;
(d)	Has had any permit revoked under the environmental laws of any state or the United States; or
(e)	Has otherwise demonstrated through clear and convincing evidence of previous actions that the applicant lacks the necessary good character and competency to reliably carry out the obligations imposed by law upon the permit holder; or

(2) The application substantially duplicates an application by the same applicant denied within the past five years which denial has not been reversed by a court of competent jurisdiction. Nothing in this subdivision may be construed to prohibit an applicant from submitting a new application for a permit previously denied, if the new application represents a good faith attempt by the applicant to correct the deficiencies that served as the basis for the denial in the original application.

All applications filed pursuant to Titles 34A and 45 shall include a certification, sworn to under oath and signed by the applicant, that he is not disqualified by reason of this section from obtaining a permit. In the absence of evidence to the contrary, that certification shall constitute a prima facie showing of the suitability and qualification of the applicant. If at any point in the application review, recommendation or hearing process, the secretary finds the applicant has intentionally made any material misrepresentation of fact in regard to this certification, consideration of the application may be suspended and the application may be rejected as provided for under this section.

Applications rejected pursuant to this section constitute final agency action upon that application and may be appealed to circuit court as provided for under chapter 1-26.”

Pursuant to SDCL 1-40-27, I certify that I have read the forgoing provision of state law, and that 1 am not disqualified by reason of that provision from obtaining the permit for which application has been made.

South Dakota Codified Laws Section 1-40-27 provides:
	“The secretary may reject an application for any permit filed pursuant to Titles 34A or 45, including any application by any concentrated swine feeding operation for authorization to operate under a general permit, upon making a specific finding that:
	(1)	The applicant is unsuited or unqualified to perform the obligations of a permit holder based upon a finding that the applicant, any officer, director, partner or resident general manager of the facility for which application has been made:
		(a)	Has intentionally misrepresented a material fact in applying for a permit;
		(b)	Has been convicted of a felony or other crime involving moral turpitude;
		(c)	Has habitually and intentionally violated environmental laws of any state or the United States which have caused significant and material environmental damage;

	(2)	The application substantially duplicates an application by the same applicant denied within the past five years which denial has not been reversed by a court of competent jurisdiction. Nothing in this subdivision may be construed to prohibit an applicant from submitting a new application for a permit previously denied, if the new application represents a good faith attempt by the applicant to correct the deficiencies that served as the basis for the denial in the original application.
	All applications filed pursuant to Titles 34A and 45 shall include a certification, sworn to under oath and signed by the applicant, that he is not disqualified by reason of this section from obtaining a permit. In the absence of evidence to the contrary, that certification shall constitute a prima facie showing of the suitability and qualification of the applicant. If at any point in the application review, recommendation or hearing process, the secretary finds the applicant has intentionally made any material misrepresentation of fact in regard to this certification, consideration of the application may be suspended and the application may be rejected as provided for under this section.

EXHIBIT S-7

Toxic Release Inventory Form

To:	Contractor
Cc:	Jim Kramer, Safety & Security Supervisor; Keith Kelly, Plant Liaison
From:	Otter Tail Power Company Environmental Services Department
Date:	August 8, 2012
Subject:	Tracking Toxic Chemical Use

Introduction

EPA and the States require Otter Tail Power Company to report toxic chemical usage and releases to the environment annually under 40 CFR 372, Emergency Planning and Community Right-to-Know Act, also known as Toxic Release Inventory (TRI). EPA has a specific list of chemicals that it is interested in for this program and
if a facility’s usage of any of these chemicals exceed a regulatory threshold, then the chemical must be reported to the EPA. The reporting threshold varies by chemical and method of usage. Since the coal burning process already triggers the reporting threshold for various chemicals at our site, any additional usage of the chemicals during construction projects, maintenance work, or other activities must be included in the annual TRI report.

Reportable Materials

In order to report the toxic chemicals used for non-combustion activities, we will need the cooperation of contractors that will be working on-site to track chemical usage and any waste disposal associated with using those chemicals. Based on EPA guidance and the experiences of other utilities, some of the products that are likely to require reporting are listed below. Unless otherwise noted products must be reported to Otter Tail Power Company the day the material is brought on site.

Product	Reportable Quantity
Paints, coatings, epoxies, except latex paint	55 gallons or more
Welding rods	Provide usage estimate at end of each calendar year to the nearest 100 welding rods
Materials containing lead	Greater than 10 pounds
Diesel fuel use in on-site equipment	Report quantity daily to Plant Liaison
Mercury	Any amount
Chemicals	Greater than 55 gallons or 500 pounds

Product Usage Report

A report of product usage must be promptly submitted to Otter Tail Power Company for each new reportable product brought on site. The report needs to contain the following information:

● Contractor company name, contact person and phone number

● Name of Product

● Product Manufacturer’s name

● Quantity of product brought on-site

● Whether there will be a waste generated from use of the product, and if so, quantity and method of waste disposal. If a waste is expected to be generated, this last part of this question will need to be updated by the contractor prior to leaving the site with the waste.

● If disposed off-site, name of disposal company and disposal location

Material Safety Data Sheets (MSDS) for products must be made available to Otter Tail Power Company once they arrive on-site. This is an OSHA requirement but the MSDS will also be used for emergency planning and TRI reporting. Because the MSDS will be used for chemical identification on TRI reporting, it is important the product name be reported as shown on the MSDS. Do not report the trade name or nickname or we will be unable to link the correct MSDS to the product use.

A sample reporting form has been attached for your convenience. While using the form is not mandatory, we suggest using some type of form or reminder to ensure all pertinent information is collected and transmitted. Reports can be given to Jim Kramer, Safety and Security Coordinator or Keith Kelly, Plant Liaison.
