F. The issuance of the Bonds to refund the Prior Bonds will provide financing on more advantageous terms for the cost of the Facilities financed by the Prior Bonds.

G. The Bonds shall be issued under and pursuant to the Trust Indenture, dated as of May 1, 2013, between the Issuer and Wells Fargo Bank, National Association, a national banking association, as trustee (the “Trustee”), pursuant to which the Issuer shall pledge and assign to the Trustee certain rights of the Issuer hereunder.


H.

-4-


(e) The information relating to the Facilities (other than estimates) furnished by the Company in writing to Chapman and Cutler LLP, as Bond Counsel, in connection with the issuance by the Issuer of the Prior Bonds and the Bonds, was, at the time furnished, and remains to the best of the Company’s knowledge, true and correct.

(f) The Facilities are (i) designed to meet applicable federal, state and local requirements for the control of pollution or the disposal of solid waste, (ii) to be used solely for purposes contemplated by the Act and (iii) located within Rosebud County, Montana.

(g) The Montana Department of Health and Environmental Sciences has certified that the pollution control facilities constituting part of the Facilities, as designed, are in furtherance of the purpose of abating or controlling atmospheric pollutants or contaminants, and water pollution, as the case may be.

(h) The Facilities consist of those facilities described in Exhibit A hereto, and the Company shall not consent to any changes in the Facilities which would adversely affect the qualification of the Facilities as a “project” under the Act or would adversely affect the exclusion of interest on the Bonds from the gross income of the Owners thereof for federal income tax purposes and therefore would adversely affect the exemption of interest on any of the Bonds from federal income taxation.

(l) To the best knowledge of the Company, no event has occurred and is continuing under the provisions of the Prior Indenture or Prior Loan Agreement which event now constitutes, or with the lapse of time or the giving of notice, or both, would constitute, an event of default under the Prior Indenture or Prior Loan Agreement.

(m) The aggregate principal amount of Bonds does not exceed the aggregate principal amount of the outstanding Prior Bonds. The final maturity date of the Bonds is no later than the final maturity date of the Prior Bonds.

(n) The Company does not, as of the date of issue of the Bonds, reasonably expect any use of moneys derived from the proceeds of the Bonds or any investment or reinvestment thereof or from the sale of the Facilities which would cause the Bonds to be classified as “arbitrage bonds” within the meaning of Section 148 of the Code.

 

-5-


(o) All of the proceeds of the Prior Bonds, including the investment earnings thereon, have been disbursed in accordance with the provisions of the Prior Indenture, and there are no proceeds of the Prior Bonds, or investment earnings therefrom, being held by the Prior Trustee under the Prior Indenture.

ARTICLE III

ISSUANCE OF THE BONDS; THE LOAN; DISPOSITION OF

PROCEEDS OF THE BONDS; THE FACILITIES

Section 3.01. Issuance of Bonds. In order to refinance the Facilities by effecting the Refunding, the Issuer shall issue the Bonds under and in accordance with the Act and pursuant to the Indenture. The Company hereby approves the issuance of the Bonds and all terms and conditions thereof.

Section 3.02. Issuance of Other Obligations. The Issuer and the Company expressly reserve the right to enter into, to the extent permitted by law, an agreement or agreements other than this Agreement with respect to the issuance by the Issuer, under an indenture or indentures other than the Indenture, of obligations to provide additional funds to pay costs of facilities in addition to the Facilities or to provide for the refunding of all or any principal amount of the Bonds. Such obligations will not be entitled to the benefits of the Indenture or the Senior Notes or any Insurance Policy, Letter of Credit or Alternate Credit Facility.

Section 3.03. The Loan; Disposition of Bond Proceeds. (a) The Issuer shall lend to the Company the proceeds of the issuance and sale of the Bonds for the purposes specified in Section 3.01 of this Agreement.

The Issuer and the Company shall cause the proceeds of the Bonds to be deposited with the Prior Trustee in a prepayment account in the Prior Bond Fund under the Prior Indenture to be used to pay the principal of the Prior Bonds upon redemption thereof; provided that proceeds of the Bonds may, if deemed necessary by the Trustee, be deposited into the Bond Proceeds Account prior to the transfer of such proceeds to the Prior Bond Fund on the Issue Date. Such proceeds may be invested in direct obligations of the United States government, obligations the principal of and interest on which are guaranteed by the United States government, or obligations of any agency or instrumentality of the United States government in accordance with the provisions of Section 90-5-107(4) of the Act. Because such Bond proceeds will not be sufficient to provide for the payment of the premium, if any, and accrued interest on the Prior Bonds upon the redemption thereof, the Company shall, on or before the Business Day prior to

 

-6-


the Redemption Date, at its own expense and without any right of reimbursement in respect thereof, pay to the Prior Trustee for deposit into such repayment account in the Prior Bond Fund under the Prior Indenture, all additional amounts necessary to effect the redemption of such Prior Bonds on the Redemption Date.

The Company shall promptly pay all Costs when due from moneys other than the proceeds of the sale of the Bonds or moneys drawn under any Letter of Credit or Alternate Credit Facility, as the case may be.

(b) The Issuer shall establish the Bond Fund with the Trustee in accordance with Section 6.01 of the Indenture. The proceeds of the issuance and sale of the Bonds constituting accrued interest, if any, shall be deposited into the Bond Fund.

Section 3.04. Changes to the Facilities. The Company may supplement or amend the Plans and Specifications relating to the Facilities as duly certified by an Authorized Company Representative (including additions thereto or omissions therefrom), provided that no such supplement or amendment shall change the description of such Facilities set forth in Exhibit A to this Loan Agreement or change the function of any principal component of such Facilities described in Exhibit A to this Loan Agreement, unless, in either case, the Trustee and the Issuer receive an opinion of Bond Counsel to the effect that, after giving effect to such change, the Facilities will constitute a “project” under the Act and that such change will not adversely affect the Tax-Exempt status of the Bonds. In the event of a supplement or amendment to the Plans and Specifications affecting the description of the Facilities or the function of any principal component of the Facilities, the Company and the Issuer shall amend Exhibit A to this Loan Agreement to reflect such supplement or amendment, which supplement or amendment shall not be considered as an amendment to this Agreement requiring the consent of any Owner, the Trustee or the Insurer for the purposes of Article XII of the Indenture. The Company may identify any proprietary information in the Plans and Specifications, and the Issuer agrees, to the extent permitted by law, to keep such information confidential. The Issuer agrees to provide the Company, to the extent permitted by law, with at least ten (10) days’ notice prior to the disclosure of any information identified by the Company as proprietary.

(b) From the date of delivery of any Letter of Credit for a series of Bonds to and including the Interest Payment Date next preceding the Expiration of the Term of the Letter of Credit (or the Expiration of the Term of an Alternate Credit Facility, as the case may be), the Company shall provide for the payment of the amounts to be paid by the Trustee pursuant to Section 3.01 and Section 3.02 of the Indenture with respect to such series by the delivery of such Letter of Credit or Alternate Credit Facility, as the case may be, to the Trustee. The Company hereby irrevocably authorizes and directs the Trustee to draw moneys under any Letter of Credit or Alternate Credit Facility in accordance with the provisions of the Indenture to obtain the moneys necessary to pay the purchase price for the related series of the Bonds payable under Section 3.01 and Section 3.02 of the Indenture if and when due. No Letter of Credit will be delivered on the Issue Date.

(B) on the Business Day next preceding the Expiration of the Term of the Letter of Credit or the Expiration of the Term of an Alternate Credit Facility, which is to be terminated, the Company shall furnish to the Trustee (prior to 9:30 a.m., New York time, on such Business Day, unless a later time on such Business Day shall be acceptable to the Trustee) an opinion of Bond Counsel stating that the termination of such Letter of Credit or Alternate Credit Facility (I) complies with the terms hereof and (II) will not adversely affect the Tax Exempt status of the Bonds.

(b) The Company may, at its election, but only with the written consent of the Bank or the Obligor on an Alternate Credit Facility, as the case may be, provide for one or more extensions of the Letter of Credit or Alternate Credit Facility then in effect, as the case may be, for any period commencing after its then-current expiration date.

Section 4.04. Issuance, Delivery and Surrender of Senior Notes and Substitute Collateral. (a) The obligation of the Company pursuant to Section 4.01 hereof to repay the loan made to it by the Issuer pursuant to Section 3.03 hereof may be secured by the Senior Notes or, subject to Section 4.04(f) hereof, by Substitute Collateral.

(b) The Senior Notes and any Substitute Collateral shall (i) mature on the same date and in the same principal amount as the related series of Bonds, (ii) bear interest at the same rate and be payable at the same times as the related series of the Bonds, (iii) contain redemption provisions correlative to the provisions of Section 4.02 and Section 4.03 of the Indenture for the related series of the Bonds, and (iv) subject to the provisions of Section 4.04(c) hereof, require payments of the principal and premium, if any, and interest on the related series to be made to the Trustee for the account of the Issuer. In addition, the Senior Notes and any Substitute

 

-10-


Collateral may be subject to optional and/or mandatory purchase at the same times as the related series of the Bonds. On the Issue Date the Senior Notes shall be delivered to and registered in the name of the Trustee (or, subject to Section 5.11 of the Indenture, the Trustee’s nominee) for the account of the Issuer and the benefit of the Owners from time to time of the related series of the Bonds and shall be held, voted, transferred and surrendered by the Trustee subject to and in accordance with the respective provisions of this Agreement, the Indenture and the Pledge Agreement. Any moneys received by the Trustee with respect to the Senior Notes shall be used to make the corresponding payment then due of principal of and premium, if any, or interest on the related series of the Bonds in accordance with the terms of such Bonds and the Indenture. Any proceeds of the Senior Notes in excess of the amounts necessary to pay in full the principal of and premium, if any, or interest on the related series of the Bonds shall be remitted to the Company.

(c) The Company shall receive a credit against its obligations to make any payment of principal of and premium, if any, or interest on a series of the Senior Notes described in Section 4.04(b) hereof (whether at maturity, upon redemption or otherwise), and such obligations shall be fully or partially, as the case may be, satisfied and discharged, in an amount equal to the amount, if any, paid by the Company under Section 4.01 hereof, or otherwise satisfied or discharged, in respect of the principal of and premium, if any, or interest on the related series of the Bonds; provided, however, that the Company shall receive no such credit for any payment with respect to any Bond made by the Insurer. The obligations of the Company to make such payment of principal of and premium, if any, or interest on such Senior Notes shall be deemed to have been reduced by the amount of such credit.

(d) In view of the pledge and assignment of the Senior Notes in accordance with Section 4.05 hereof, the Issuer agrees that, on the Issue Date and for so long as the Company’s obligation under Section 4.01 hereof to repay the loan made to it pursuant to Section 3.03 hereof is secured by the Senior Notes, (i) the Senior Notes shall be issued and delivered to, registered in the name of and held by the Trustee (or, subject to Section 5.11 of the Indenture, the Trustee’s nominee) for the benefit of the Owners from time to time of the related series of the Bonds, and the Company shall make all payments of principal of and premium, if any, and interest on the applicable series of the Senior Notes to the Trustee as the registered owner thereof; (ii) the Indenture shall provide that the Trustee shall not sell, assign or transfer the Senior Notes except to a successor trustee under the Indenture and shall surrender Senior Notes to the Senior Note Indenture Trustee in accordance with the provisions of Section 4.04(e) and Section 4.04(f) hereof; and (iii) the Company may take such actions as it shall deem to be desirable to effect compliance with such restrictions on transfer, including the placing of an appropriate legend on each Senior Note and the issuance of stop-transfer instructions to the Senior Note Indenture Trustee or any other transfer agent under the Senior Note Indenture.

(e) At the time any Bonds cease to be Outstanding (other than by reason of the payment of the related series of the Senior Notes or by reason of the payment of principal of or interest on such Bonds by the Insurer, and other than those Bonds in lieu of or in exchange or substitution for which other Bonds shall have been authenticated and delivered), the Issuer shall cause the Trustee to surrender to the Senior Note Indenture Trustee a corresponding principal amount of the related series of Senior Notes bearing interest at the same rate and maturing on the same date as such Senior Notes.

 

-11-


(f) On any Business Day the Company may provide for the release of its Senior Notes by delivering Substitute Collateral to the Trustee to secure the obligation of the Company to repay the loan made to it pursuant to Section 3.03 hereof, but only if the Company shall, on the date of delivery of such Substitute Collateral, simultaneously deliver to the Trustee:

(i) an opinion of Bond Counsel stating that delivery of such Substitute Collateral and release of the related Senior Notes (1) complies with the terms hereof and (2) will not adversely affect the Tax-Exempt status of the related series of the Bonds;

(ii) written evidence from any applicable Insurer, the Bank or Obligor on an Alternate Credit Facility, as the case may be, to the effect that it has reviewed the proposed Substitute Collateral and finds the same to be acceptable; and

(iii) written evidence from Moody’s, if the related series of the Bonds are then rated by Moody’s, and from S&P, if the related series of the Bonds are then rated by S&P, in each case to the effect that such rating agency has reviewed the Substitute Collateral and that the release of the Senior Notes and the substitution of the Substitute Collateral for the related Senior Notes will not, by itself, result in a reduction, suspension or withdrawal of such rating agency’s rating or ratings of such Bonds.

The Indenture shall provide that, to the extent that Substitute Collateral is delivered to the Trustee in compliance with this Section 4.04(f), the Trustee shall surrender to the Senior Note Indenture Trustee a corresponding principal amount of Senior Notes.

(g) On any day on which the Bonds of a series are subject to mandatory purchase pursuant to Section 3.02 of the Indenture, the Company may provide for the release of its related Senior Notes, provided that the Company delivers:

(i) to the Trustee and the Remarketing Agent, in conjunction with the notice required by Section 2.02(b)(ii), Section 2.02(c)(ii), Section 2.02(d)(ii), or Section 2.02(e)(ii) of the Indenture or Section 4.03 hereof, a notice which (A) states the effective date of the release of such Senior Notes, which date shall be the date on which the related Bonds are subject to mandatory purchase, and (B) directs the Trustee to give notice, in conjunction with the notice required by Section 2.02(b)(iii), Section 2.02(c)(iii), Section 2.02(d)(iii), Section 2.02(e)(iii), or Section 3.02(c) of the Indenture, of the release of such Senior Notes and the mandatory purchase of the related Bonds, in whole, on the effective date of the release of such Senior Notes; and

(ii) to the Trustee, on or before the effective date of the release of the Senior Notes, an opinion of Bond Counsel stating, in effect, that the release of the Senior Notes (A) is authorized under this Agreement, and (B) will not adversely affect the Tax-Exempt status of the related series of Bonds.

Section 4.05. Payments Assigned; Obligation Absolute. It is understood and agreed that all Loan Payments and all payments to be made by the Company on the Senior Notes are, by the Indenture and the Pledge Agreement, pledged and assigned by the Issuer to the Trustee, and that all rights and interests of the Issuer hereunder (except for the rights of the Issuer under Section 4.06, Section 4.08, Section 5.03, Section 5.06, Section 5.07, Section 5.08, Section 7.05 and Section 7.07 hereof and any rights of the Issuer to receive notices, certificates, requests, requisitions, directions and other communications hereunder), including the right to delivery of the Senior Notes, are pledged and assigned to the Trustee pursuant to the Indenture and the Pledge Agreement.

Section 4.06. Payment of Expenses. The Company shall pay all of the Administration Expenses of the Issuer, the Trustee, the Paying Agent, the Registrar, Moody’s and S&P under the Indenture and of the Remarketing Agent under the Remarketing Agreement directly to each such entity. The Company shall also pay all of the expenses of the Prior Trustee in connection with the Refunding and all other reasonable fees and expenses incurred in connection with the issuance of the Bonds, including, but not limited to, all costs associated with any discontinuance of the book-entry system described in Section 2.10 of the Indenture.

Section 4.07. Indemnification. The Company releases the Trustee and the Registrar and their respective officers, agents, servants and employees from, agrees that the Trustee and the Registrar and their respective officers, agents, servants and employees shall not be liable for, and agrees to indemnify and hold free and harmless the Trustee and the Registrar and their respective officers, agents, servants and employees from and against, any liability for any loss or damage to property or any injury to or death of any person that may be occasioned by any cause whatsoever pertaining to the Project, except in any case as a result of the negligence or willful misconduct of the Trustee and the Registrar and their respective officers, agents, servants and employees.

The Company will indemnify and hold free and harmless the Trustee and the Registrar and their respective officers, agents, servants and employees from and against any loss, claim, damage, tax, penalty, liability, disbursement, litigation or other expenses, attorneys’ fees and expenses or court costs arising out of, or in any way relating to, the execution or performance of this Agreement, the Tax Certificate, the issuance or sale of the Bonds, the Refunding, acceptance or administration of the trust under the Indenture or any other cause whatsoever pertaining to this Agreement, the Tax Certificate, the Indenture or the Insurance Policy, if any, except in any case as a result of the negligence or willful misconduct of the Trustee and the Registrar or their respective officers, agents, servants and employees.

Section 4.08. Payment of Taxes and Charges in Lieu Thereof. (a) The Company covenants and agrees that it will, from time to time, promptly pay and discharge or cause to be paid and discharged when due its share of all taxes, assessments and other governmental charges lawfully imposed upon the Project or any part thereof or upon income and profits thereof or any payments hereunder or on the Senior Notes.

(b) The Company shall pay or cause to be satisfied and discharged or make adequate provision to satisfy and discharge (including the provisions of adequate bonding therefor) within 60 days after the same shall accrue, any lien or charge upon the Loan Payments or payments under Section 4.02 hereof or amounts payable on the Senior Notes, and all lawful claims or demands for labor, materials, supplies or other charges which, if unpaid, might be or become a lien thereon; provided that the Company may, at its expense and in its own name and behalf or in the name and behalf of the Issuer, in good faith contest any such taxes, assessments and other charges and, in the event of any such contest, may permit the taxes, assessments or other charges so contested to remain unpaid during the period of such contest and any appeal therefrom; provided further that during such period enforcement of such contested item is effectively stayed, unless by nonpayment of any such items the lien of the Indenture as to the amounts payable hereunder or on the Senior Notes will be materially endangered, in which event the Company shall promptly pay and cause to be satisfied and discharged all such unpaid items. The Issuer will cooperate fully with the Company in any such contest. In the event that the Company shall fail to pay any of the foregoing items required by this Section to be paid by the Company, the Issuer or the Trustee may (but shall be under no obligation to) pay the same, and any amounts so advanced therefor by the Issuer or Trustee shall become an additional obligation of the Company to the party making the advance. The Company agrees to repay the amounts so advanced, from the date thereof, together (to the extent permitted by law) with interest thereon until paid at a rate per annum which is one percentage point greater than the highest rate per annum borne by any of the Bonds.

Section 4.09. Compliance with Prior Loan Agreement. The Company hereby confirms its obligations to furnish any moneys required to be deposited with the Prior Trustee under the Prior Indenture in order to redeem the Prior Bonds on the Redemption Date, to the extent that the proceeds of the Bonds on deposit with the Prior Trustee, together with any investment earnings thereon, is less than the amount required to pay the principal of and applicable redemption premium and interest on such Prior Bonds upon their redemption on the Redemption Date.

(b) The Company covenants to comply with the provisions of Section 148 of the Code and the related United States Treasury Regulations, including temporary and proposed regulations, during the term of the Bonds, including, but not limited to, the provisions for rebate of certain earnings to the United States to the extent the same apply to the Bonds, in accordance with the Tax Certificate.

ARTICLE VIII

PURCHASE OR REDEMPTION OF BONDS

Section 8.01. Redemption of Bonds. The Issuer shall take or cause to be taken the actions required by the Indenture (other than the payment of money) to discharge the lien thereof through the redemption, or provision for payment or redemption, of all Bonds of a series then Outstanding, or to effect the redemption, or provision for payment or redemption, of less than all the Bonds of a series then Outstanding, upon receipt by the Issuer and the Trustee from an Authorized Company Representative of a written notice designating the principal amount of the Bonds of a series to be redeemed and specifying the date of redemption (which shall not be less than 30 days from the date such notice is given) and the applicable redemption provision of the Indenture. Unless otherwise stated therein, any such notice with respect to a redemption pursuant to Section 4.02 of the Indenture shall be revocable by the Company at any time prior to the time at which such Bonds are to be redeemed, or for the payment or redemption of which provision is to be made, are first deemed to be paid in accordance with Article VIII of the Indenture. The Company shall furnish any moneys required by the Indenture to be deposited with the Trustee or otherwise paid by the Issuer in connection with any of the foregoing

 

-22-


purposes. In connection with any redemption of any Bonds, the Company shall provide to the Trustee the names and addresses of the Securities Depositories and Information Services as contemplated by Section 4.05 of the Indenture. The Company shall provide to the Bank (or Obligor on an Alternate Credit Facility, as the case may be) a copy of any notice given pursuant to this Section.

Unless the notice is revoked by the Company as described in the preceding paragraph, whenever the Company shall have given any notice of prepayment of the amounts payable hereunder pursuant to this Article VIII, which includes a notice for redemption of the Bonds pursuant to the Indenture, all amounts payable under the first paragraph of this Section 8.01 shall become due and payable on the date fixed for redemption of such Bonds.

Section 8.02. Purchase of Bonds. The Company may at any time, and from time to time, furnish moneys to the Trustee accompanied by a notice directing such moneys to be applied to the purchase of a series of Bonds in accordance with the provisions of the Indenture delivered pursuant to the Indenture, which Bonds shall, at the direction of the Company, be delivered in accordance with Section 3.06(a)(iv) of the Indenture.

Section 8.03. Obligation to Prepay. (a) The Company shall be obligated to prepay in whole or in part the amounts payable hereunder upon a Determination of Taxability (as defined below) or other event giving rise to a mandatory redemption of the Bonds pursuant to Section 4.03 of the Indenture, by paying an amount equal to, when added to other funds on deposit in the Bond Fund, (i) the aggregate principal amount of the Bonds to be redeemed pursuant to the Indenture plus accrued interest to the redemption date, plus (ii) an amount of money equal to the Trustee’s fees and expenses under the Indenture accrued and to accrue until such redemption of such Bonds, plus (iii) an amount of money equal to all sums due to the Issuer under this Agreement.

(b) The Company shall cause a mandatory redemption to occur within 180 days after a Determination of Taxability (as defined below) shall have occurred. A “Determination of Taxability” shall be deemed to have occurred if as a result of an Event of Taxability, a final decree or judgment of any federal court or a final action of the Internal Revenue Service determines that interest paid or payable on any Bond is or was includible in the gross income of an Owner of the Bonds for federal income tax purposes under the Code (other than an Owner who is a “substantial user” or “related person” within the meaning of Section 103(b)(13) of the 1954 Code). However, no such decree or action will be considered final for this purpose unless the Company has been given written notice and, if it is so desired and is legally allowed, has been afforded the opportunity to contest the same, either directly or in the name of any Owner of a Bond, and until conclusion of any appellate review, if sought. If the Trustee receives written notice from any Owner of a Bond stating (a) that the Owner has been notified in writing by the Internal Revenue Service that it proposes to include the interest on any Bond in the gross income of such Owner for the reasons described therein or any other proceeding has been instituted against such Owner which may lead to a final decree or action as described herein, and (b) that such Owner will afford the Company the opportunity to contest the same, either directly or in the name of the Owner, until a conclusion of any appellate review, if sought, then the Trustee shall promptly give notice thereof to the Company, the Insurer, the Bank (or the Obligor on an

 

-23-


Alternate Credit Facility, as the case may be), the Issuer, the Remarketing Agent and the Owner of each Bond then Outstanding. If a final decree or action as described above thereafter occurs and the Trustee has received written notice thereof as provided in Section 8.01 hereof at least 45 days prior to the redemption date, the Trustee shall make the required demand for prepayment of the amounts payable hereunder and give notice of the redemption of the Bonds at the earliest practical date, but not later than the date specified in this Article, and in the manner provided by Section 4.05 of the Indenture.

At the time of any such prepayment of the amounts payable hereunder pursuant to this Section, the prepayment amount shall be applied, together with other available moneys in the Bond Fund, to the redemption of the Bonds on the date specified in the notice as provided in the Indenture, whether or not such date is an Interest Payment Date, to the Trustee’s fees and expenses under the Indenture accrued to such redemption of the Bonds, and to all sums due to the Issuer under this Agreement.

Whenever the Company shall have given any notice of prepayment of the amounts payable hereunder pursuant to this Article VIII, which includes a notice for redemption of the Bonds pursuant to the Indenture, all amounts payable under the first paragraph of this Section 8.03 shall become due and payable on the date fixed for redemption of such Bonds.

Section 8.04. Compliance With Indenture. Anything in this Agreement to the contrary notwithstanding, the Issuer and the Company shall take all actions required by this Agreement and the Indenture in order to comply with the provisions of Article III of the Indenture.

FACILITIES DESCRIPTION

Description of Facilities – 1973 Bonds

The Facilities generally consist of the following property or other property functionally related and subordinate to such property. The following describes the Facilities originally financed by certain Pollution Control Revenue Bonds (Puget Sound Power & Light Company Project) Series 1973, issued by the County of Rosebud, Montana on June 27, 1973.

 

1. Venturi Scrubber System

The function of the Venturi Scrubbing System is to remove fly ash and sulfur dioxide (SO2) from the flue gas by washing with a recycled liquor.

This system, together with a related monitoring device, is composed of three scrubber trains each at Units 1 and 2, each containing a venturi throat, counter-current sprays, mist eliminators, recycle tank, recycle pumps, steam coil-type reheater, soot blowers, induced draft (“ID”) fan, effluent liquor pumps and lines, and pond return pumps. Flue gas first passes down through the venturi throat section and is thoroughly mixed with the liquor. The liquor drops out into the integral recycle tank with the absorbed ash and some absorbed SO2. Gas then passes upward through sprays and demisters where downward flowing liquor finishes the SO2 absorption job. The liquor drops out into the recycle tank. The gas passes on through a reheater before entering the ID fans and exiting out the stack. Spent liquor is pumped to an ash disposal pond by effluent liquor pumps and clear water is returned to the cycle by the pond return pumps.

The ash pond is divided into two sections each of which is used on alternate years. One section is to be left to dry and the deposited ash will be disposed of as required while the other section is in use. Ash mixed with water enters the active pond and moves slowly toward the outlet. Before reaching the outlet, most of the ash has settled out and decanted water is returned to the cycle for reuse. The pond will also have adequate capacity for disposal of the smaller amounts of ash from the ash disposal system (see Ash Disposal System below).

 

2. Nitrogen Oxides Control System

The function of the Nitrogen Oxides Control System is to reduce the amount of nitrogen oxides (NOX) produced during the combustion of pulverized coal in the boiler.

This system consists of four overfire air compartments each at Units 1 and 2 with associated ducting, air dampers, and combustion controls. In operation, this system functions to decrease combustion temperatures and NOX production by increasing the

 

A-1


volume of the fireball region in which combustion takes place. This is accomplished by installation and control of overfire air compartments that spread the supply of combustion air over a larger volume.

 

3. Ash Disposal System

The function of the Ash Disposal System is to dispose of bottom ash, economizer ash, and pyrites produced in the operation of the plants.

This system is composed of hoppers, storage tanks, clinker grinders, ash conveying pumps, conveying lines, water supply lines, pond return lines, and ash ponds. Economizer ash is conveyed pneumatically from the economizer hoppers to the pyrites and economizer storage tank. The pyrites, which are rejected by the coal pulverizers, are also sluiced to this storage tank. The storage tank is emptied periodically by sluicing the contents to the ash pond. Ash and clinkers falling into the bottom ash hopper are put through the clinker grinder and sluiced to the ash pond.

Description of Facilities – 1977 Bonds

The Facilities generally consist of the following property or other property functionally related and subordinate to such property. The following describes the Facilities originally financed by certain Pollution Control Revenue Bonds (Puget Sound Power & Light Company Project) Series 1977, issued by the County on June 22, 1997.

 

1. Sulfur Dioxide and Particulate Removal System

The Sulfur Dioxide and Particulate Removal System is composed of a SO2 scrubber and a fly ash slurry disposal system as described below.

 

  A. Venturi Scrubber System

The function of the Venturi Scrubber System is to remove fly ash and SO2 from the flue gas washing with a recycled liquor.

The scrubbers were designed and installed by Combustion Equipment Associates and Inc. Particulate loading in the scrubber gases shall be equal to or less than 0.18 grains per actual cubic foot measured at the reheater outlet condition (equivalent to 0.02 grains per actual cubic foot in the stack). SO2 in the scrubber gases are equal to or less than one pound of SO2 per million BTU of heat released in the furnace. The design conditions are for a flue gas flow of 1,430,000 cubic feet per minute per generating unit at 291OF. This system, together with a related monitoring device, is composed of three scrubber trains each at Units 1 and 2, each containing a venturi throat, counter-current sprays, mist eliminators, recycle tank, recycle pumps, steam coil-type reheater, soot blowers, ID fan, effluent liquor pumps and lines, and pond return pumps. Flue gas first passes down through the venturi throat section and is thoroughly mixed with the liquor. The liquor drops out into the integral recycle tank with the absorbed ash and some absorbed SO2. Gas then passes upward through sprays and demisters where downward flowing liquor completes the SO2 absorption process. The liquor again drops out into the recycle tank. The gas passes on through a reheater before entering the ID fans and exiting out the stack. Spent liquor is pumped to a fly ash slurry disposal pond by effluent liquor pumps and clear water is returned to the recycle tank by the pond return pumps.

The Venturi Scrubber System is composed of scrubber vessels, venturi throats, recycle tanks, agitators, recycle pumps, counter-current sprays, wash trays, wash tray recycle tank, wash tray recycle pumps, wash tray pond, mist eliminators and cleaning sprays, steam coil reheaters, soot blowers, ID fans, isolation dampers, effluent tank, effluent pumps, fly ash pond, pond return pumps, lime (alkali) system, valves, pipelines, wiring, electric services, electric motors, valve actuators, motor controls, automatic analog control system, related measuring instruments and monitoring devices and all other related auxiliary electric, mechanical, and civil equipment.

 

A-3


  B. Ash Disposal System

The Ash Disposal System serves to dredge and pump fly ash slurry from the fly ash slurry disposal pond, mentioned above, to the evaporation pond and return reclaimed water to the fly ash slurry pond. Eventually the evaporation pond will fill with slurry. A new pond will then be started and the slurry in the old pond will be left to evaporate to a more solid material.

The system included a barge mounted dredge, booster pumps, a 16” diameter slurry pipeline, evaporation pond, a barge mounted return line pump, emergency drain pumps, sump pumps, seal water pumps, all electrical services, valves, miscellaneous piping, and all other necessary equipment.

 

3. Nitrogen Control System

The Nitrogen Control System serves to reduce the concentration of NOX in the flue gas.

The system consists of four overfire air compartments per generating unit and associated ducting, air dampers, and combustion controls. In operation, the system functions to decrease combustion temperatures and NOX production by increasing the volume of the fireball region in which combustion takes place. This is accomplished by the installation and control of overfire air compartments that spread the supply of combustion air over a larger volume.

Description of Facilities – 1981 Bonds

The Facilities generally consist of the following property or other property functionally related and subordinate to such property. The following describes the Facilities originally financed by the Issuer’s $100,000,000 aggregate principal amount 8 3/4% Pollution Control Revenue Bonds, Series 1981, issued on June 3, 1981.

 

1. Scrubber System

The function of the Scrubber System is to remove fly ash and sulfur dioxide (SO2) from the flue gas by washing with a recycled liquor. Eight scrubber vessels are installed each at Unit 3 and 4 into which boiler combustion gases are ducted. At full load it requires that seven scrubbers operational to achieve sufficient SO2 and particulate removal to comply with environmental regulations. Since it was expected that at any given time at least one scrubber train will be down for maintenance, it was necessary to install eight scrubber trains in order to assure reliable plant operation in compliance with the law.

The flue gas enters the top of each scrubber vessel in the venturi section where the gas is contacted with finely atomized scrubber slurry. The flue gas is adiabatically cooled and saturated by the evaporation of water from the scrubber slurry. In the venturi, fly ash particulates are removed by the slurry droplets during collisions caused by the sudden changes in gas velocity. The proper gas pressure drop across the venturi to achieve these changes in velocity is maintained by raising or lowering a plumb bob located in the throat of the venturi.

SO2 is also absorbed and removed by the slurry in the venturi. After the flue gas leaves the venturi, it passes upward through an absorption spray zone where the gas is sprayed with more scrubber slurry. These sprays remove additional SO2. Then the flue gas passes through a wash tray where it is bubbled through a stream of wash tray slurry. The main purpose of the wash tray is to remove and dilute the slurry droplets entrained in the flue gas from the venturi and absorption sprays. The wash tray also removes small amounts of fly ash and SO2. A spray keeps the wash tray from plugging and also maintains the proper water balance in the scrubber. When the flue gas bubbles through the wash tray it produces a mist of water droplets containing some dissolved and suspended solids. This mist is removed by a mist eliminator. The mist eliminator is made up of a series of zigzag parallel plates. The mist droplets strikes these plates, cling to them, and then fall back onto the wash tray. The flue gas then leaves the scrubber vessel. At this point the flue gas has been cooled to a temperature of about 120OF and is saturated as a result of water introduced in the scrubbing process. Approximately 95% of the SO2 and over 90% of the fly ash particulates are removed.

Because of the action of the scrubber in cooling and saturating the flue gas, the pressure drop across the scrubber and the moisture contents adverse conditions for the continued flow of gases to and up the stack. It is therefore necessary to reheat the gases

 

A-5


to about 170OF and, thereafter, to restore the gas flow with ID fans. The reheater is another heat exchanger device that utilizes steam from the turbine or boiler. The heat in the reheater vaporizes any water droplets in the gas stream and at the same time raises the temperature of the gas to achieve a relative humidity below the saturation point. This improves the plum rise from the stack, reduces ground level concentrations of the emissions, and prevents the formation of acid mist that would cause corrosion and failure of equipment downstream of the scrubber. Upon leaving the reheater the flue gas enters an ID fan that serves to maintain the gas flow through the scrubber and reheater and forces it through the duct and up the stack. Units 3 and 4 are designed as balanced draft units that require forced draft fans at the furnace inlet and ID fans at the scrubber outlet. The flue gas temperature is increased to about 190OF by the compression in the fan.

Each scrubber vessel is provided with one reheater and one ID fan. When the flue gas leaves the fan it enters a series of ducts where the flue gas from all of the scrubbers are combined and routed to the bottom of the stack. Each of Units 3 and 4 has its own stack that discharges the cleaned gases to the atmosphere at an elevation of 692 feet above the ground.

The slurry used for the venturi and absorption sprays are taken from the recycle tank located directly below each scrubber vessel. There are two pumps for the venturi; one operates as a spare. One-half of the slurry to the venturi is injected on the tangential shelf above the venturi and the other half is sprayed on top of the plump bob. There are also two pumps per scrubber vessel for the absorption sprays. Each pump supplies slurry to one set of sprays. The sets of sprays are located one above the other. Each set of sprays is operated independently of the other. Only one set of sprays are operated so long as the outlet SO2 emissions are below the level determined by the permits. The capability to operate two sets of sprays at once is necessary to insure that the outlet SO2 concentration will never exceed the limit permitted. The spent slurry from the venturi and absorption sprays falls to the vessel bottom and is returned to the recycle tank through downcomer pipes.

The removal of fly ash and SO2 causes the buildup of suspended solid particles in the recycle tank. An agitator is used to keep these solids suspended and to promote mixing. The concentration of these suspended solids is controlled by taking a slurry bleed stream to the disposal pond where the solids settle out producing a sludge. The clear water is then returned to the recycle tank. Slurry from each recycle tank is bled to an effluent holding tank. There is one effluent holding tank for each four-scrubber vessels (two per unit). All of the effluent holding tanks discharge to one large effluent holding tank common to both units, which then discharges to the disposal pond.

The alkali used for SO2 removal is a mixture of hydrated high calcium lime and hydrated dolomitic lime (as further described in Item 3 below). This lime is added to the regenerator as a slurry. There is one regenerator per recycle tank. There is one regenerations tank feed pump per recycle tank that takes a stream of recycle slurry to the regenerator. The regenerator has an overflow line that returns regenerated slurry to the recycle tank. The purpose of the regenerators is to maintain a chemical environment different from the recycle tanks, which is more favorable to the chemical reactions necessary to regenerate the spent slurry after SO2 removal.

 

A-6


There is a separate wash tray recycle tank from which slurry is pumped to the wash tray and the wash tray undersprays. There is one wash tray recycle tank for each two-scrubber vessels (four wash tray recycle tanks per unit). A bleed stream is taken from each wash tray recycle pump in order to remove the suspended solids collected by the wash tray. This bleed stream goes to the wash tray bleed tank (one wash tray bleed tank per unit). The wash tray bleed tank discharges to the wash tray pond. All wash tray recycle tanks and wash tray bleed tanks are equipped with agitators to prevent the suspended solids from settling out. The wash tray bleed tank is discharged to the wash tray pond where the suspended solids are allowed to settle out forming a sludge at the bottom of the pond. The clear water is then returned to the wash tray recycle tanks.

The bottom of the mist eliminator is intermittently sprayed with blowdown water from the Plant’s cooling tower. This is dome to clean the mist eliminator and is also the major source of makeup water for the scrubber system. The top of each mist eliminator is also sprayed once per day for 1-1/2 minutes with river water.

 

2. Scrubber Sludge Disposal System

Effluent slurry is carried from the Plant to the sludge disposal pond by a 16” pipe. The suspended solids settle to the pond bottom and the clear water is pumped back to the Plant by two 3,020 gallon per minute pumps. One pump acts as a spare. The pond return pipe is 18” in diameter.

The sludge disposal pond (called Areas 5 and 6) is approximately three miles southeast of the Plant. There was a two phases in the development of this pond. Phase 1 required the construction of one dam 70’ high and 400’ in length. The capacity of Phase 1 is 8,000 acre-feet and it lasted approximately 13 1/2 years.

The development of Phase 2 required that the original dam be raised to 130’ in height and increased to a length of 3,000 feet. A saddle dam was also added. The saddle dam varies in height, with a maximum height of 50’ and a total length of 3,300 feet. The capacity of Phase 2 is an additional 8,900 acre-feet and it will last approximately 14 1/2 years, for a total life of 28 years.

The sludge disposal pond design took into account a permit requirement for minimum seepage, by providing low permeability soil blankets where exploration defined porous outcrops or high permeability soils.

 

3. Scrubber Lime System

The sole purpose of the Scrubber Lime System is to supply the lime slurry as needed by the scrubber regenerators. There is one lime system that serves the 16 scrubbers for Units 3 and 4 at the Plant.

 

A-7


The hydrated high calcium lime (calcium hydroxide) is produced from calcined high calcium lime (calcium oxide). Calcined high calcium lime is brought from an outside source and delivered to the Plant by truck or rail. The trucks or rail cars are pneumatically unloaded to large storage silos. From there the calcined high calcium lime is transferred to the slakers. There are four slakers. In the slakers, calcined high calcium lime is reacted with water to produce a slurry of hydrated high calcium lime. The slakers are equipped with screw conveyors for grit removal. The high calcium lime slurry from the slakers is fed to the slurry transfer tanks where it is diluted with water and mixed with hydrated dolomitic lime slurry (a mixture of calcium hydroxide and magnesium hydroxide). The lime slurry from the slurry transfer tanks is then pumped to the slurry feed storage tanks where it is distributed to the regenerators as needed. There is one feed storage tank for each four regenerators (two slurry feed storage tanks per unit).

The hydrated dolomitic lime is produced from calcined dolomitic lime (a mixture of calcium oxide and magnesium oxide). Calcined dolomitic lime is bought from an outside source and delivered to the Plant by rail car. The rail cars are pneumatically unloaded to large storage silos. From there the calcined dolomitic lime is transferred to the hydrator. In the hydrator calcined dolomitic lime is mixed with water and converted to hydrated dolomitic lime under pressure. The hydrator product is dry material. It is then mixed with water to form a slurry. Hydrated dolomitic lime slurry is fed to the slurry transfer tanks where it is mixed with hydrated high calcium lime and water to form the lime slurry. All tanks in the Scrubber Lime System are equipped with agitators.

The Scrubber Lime System is functionally related and subordinate to the scrubber systems and is not used in conjunction with any other part of the generating units.

 

4. Solid Waste Disposal System

The Solid Waste Disposal System is designed to collect and dispose of approximately 46% of the maximum total ash generated at Units 3 and 4. This represents a nominal 19 tons per hour of bottom ash, 6.9 tons per hour of fly ash, and 2.7 tons per hour of mill pyrites. The collection system for Units 3 and 4 comprise s three sets of fly ash hoppers (economizer, air heater, and flue gas duct hoppers), pyrite hoppers and the bottom ash hopper. Ash is conveyed from these hoppers to an 18,000-gallon transfer tank using jet pulsion pump and a hydroconveyor exhauster. Two two-stage material handling pump installations with a total capacity of 3,130 gallons per minute then convey this ash and water through abrasion-resistant piping. The pipe leaves the building and runs to a settling pond approximately 2,800 feet southeast of the Plant. The water used for the raw-water makeup required to offset evaporation losses. Pump-supplied return lines from the settling pond return supernatant water to an intermediate clear water pond, which than gravity-flows back through the building walls to the suction side of the ash water pumps to complete the closed loop.

Description of Facilities – 1982 Bonds

The Facilities generally consist of the following property or other property functionally related and subordinate to such property. The following describes the Facilities originally financed by the Issuer’s $115,000, 000 aggregate principal amount Floating Rate Monthly Demand Pollution Control Revenue Bonds (Puget Sound Power & Light Company Colstrip Project) Series 1982, issued on July 21, 1982.

 

1. Scrubber System

The function of the Scrubber System is to remove fly ash and sulfur dioxide (SO2) from the flue gas by washing with a recycled liquor. Eight scrubber vessels are installed each at Unit 3 and 4 into which boiler combustion gases are ducted. At full load it requires that seven scrubbers operational to achieve sufficient SO2 and particulate removal to comply with environmental regulations. Since it was expected that at any given time at least one scrubber train will be down for maintenance, it was necessary to install eight scrubber trains in order to assure reliable plant operation in compliance with the law.

The flue gas enters the top of each scrubber vessel in the venturi section where the gas is contacted with finely atomized scrubber slurry. The flue gas is adiabatically cooled and saturated by the evaporation of water from the scrubber slurry. In the venturi, fly ash particulates are removed by the slurry droplets during collisions caused by the sudden changes in gas velocity. The proper gas pressure drop across the venturi to achieve these changes in velocity is maintained by raising or lowering a plumb bob located in the throat of the venturi.

SO2 is also absorbed and removed by the slurry in the venturi. After the flue gas leaves the venturi, it passes upward through an absorption spray zone where the gas is sprayed with more scrubber slurry. These sprays remove additional SO2. Then the flue gas passes through a wash tray where it is bubbled through a stream of wash tray slurry. The main purpose of the wash tray is to remove and dilute the slurry droplets entrained in the flue gas from the venturi and absorption sprays. The wash tray also removes small amounts of fly ash and SO2. A spray keeps the wash tray from plugging and also maintains the proper water balance in the scrubber. When the flue gas bubbles through the wash tray it produces a mist of water droplets containing some dissolved and suspended solids. This mist is removed by a mist eliminator. The mist eliminator is made up of a series of zigzag parallel plates. The mist droplets strikes these plates, cling to them, and then fall back onto the wash tray. The flue gas then leaves the scrubber vessel. At this point the flue gas has been cooled to a temperature of about 120OF and is saturated as a result of water introduced in the scrubbing process. Approximately 95% of the SO2 and over 90% of the fly ash particulates are removed.

Because of the action of the scrubber in cooling and saturating the flue gas, the pressure drop across the scrubber and the moisture contents adverse conditions for the

 

A-10


continued flow of gases to and up the stack. It is therefore necessary to reheat the gases to about 170OF and, thereafter, to restore the gas flow with ID fans. The reheater is another heat exchanger device that utilizes steam from the turbine or boiler. The heat in the reheater vaporizes any water droplets in the gas stream and at the same time raises the temperature of the gas to achieve a relative humidity below the saturation point. This improves the plum rise from the stack, reduces ground level concentrations of the emissions, and prevents the formation of acid mist that would cause corrosion and failure of equipment downstream of the scrubber. Upon leaving the reheater the flue gas enters an ID fan that serves to maintain the gas flow through the scrubber and reheater and forces it through the duct and up the stack. Units 3 and 4 are designed as balanced draft units that require forced draft fans at the furnace inlet and ID fans at the scrubber outlet. The flue gas temperature is increased to about 190OF by the compression in the fan.

Each scrubber vessel is provided with one reheater and one ID fan. When the flue gas leaves the fan it enters a series of ducts where the flue gas from all of the scrubbers are combined and routed to the bottom of the stack. Each of Units 3 and 4 has its own stack that discharges the cleaned gases to the atmosphere at an elevation of 692 feet above the ground.

The slurry used for the venturi and absorption sprays are taken from the recycle tank located directly below each scrubber vessel. There are two pumps for the venturi; one operates as a spare. One-half of the slurry to the venturi is injected on the tangential shelf above the venturi and the other half is sprayed on top of the plump bob. There are also two pumps per scrubber vessel for the absorption sprays. Each pump supplies slurry to one set of sprays. The sets of sprays are located one above the other. Each set of sprays is operated independently of the other. Only one set of sprays are operated so long as the outlet SO2 emissions are below the level determined by the permits. The capability to operate two sets of sprays at once is necessary to insure that the outlet SO2 concentration will never exceed the limit permitted. The spent slurry from the venturi and absorption sprays falls to the vessel bottom and is returned to the recycle tank through downcomer pipes.

The removal of fly ash and SO2 causes the buildup of suspended solid particles in the recycle tank. An agitator is used to keep these solids suspended and to promote mixing. The concentration of these suspended solids is controlled by taking a slurry bleed stream to the disposal pond where the solids settle out producing a sludge. The clear water is then returned to the recycle tank. Slurry from each recycle tank is bled to an effluent holding tank. There is one effluent holding tank for each four-scrubber vessels (two per unit). All of the effluent holding tanks discharge to one large effluent holding tank common to both units, which then discharges to the disposal pond.

The alkali used for SO2 removal is a mixture of hydrated high calcium lime and hydrated dolomitic lime (as further described in Item 3 below). This lime is added to the regenerator as a slurry. There is one regenerator per recycle tank. There is one regenerations tank feed pump per recycle tank that takes a stream of recycle slurry to the regenerator. The regenerator has an overflow line that returns regenerated slurry to the

 

A-11


recycle tank. The purpose of the regenerators is to maintain a chemical environment different from the recycle tanks, which is more favorable to the chemical reactions necessary to regenerate the spent slurry after SO2 removal.

There is a separate wash tray recycle tank from which slurry is pumped to the wash tray and the wash tray undersprays. There is one wash tray recycle tank for each two scrubber vessels (four wash tray recycle tanks per unit). A bleed stream is taken from each wash tray recycle pump in order to remove the suspended solids collected by the wash tray. This bleed stream goes to the wash tray bleed tank (one wash tray bleed tank per unit). The wash tray bleed tank discharges to the wash tray pond. All wash tray recycle tanks and wash tray bleed tanks are equipped with agitators to prevent the suspended solids from settling out. The wash tray bleed tank is discharged to the wash tray pond where the suspended solids are allowed to settle out forming a sludge at the bottom of the pond. The clear water is then returned to the wash tray recycle tanks.

The bottom of the mist eliminator is intermittently sprayed with blowdown water from the Plant’s cooling tower. This is dome to clean the mist eliminator and is also the major source of makeup water for the scrubber system. The top of each mist eliminator is also sprayed once per day for 1-1/2 minutes with river water.

1. Air Pollution Control Facility

The air pollution control facility installed as part of Units 3 & 4 include a series of wet lime slurry based scrubbers and related equipment to remove sulfur dioxide and fly ash from the flue gases prior to discharge through stacks to the atmosphere as required by applicable environmental regulations. The lime slurry comes in contact with flue gas in order to absorb the sulfur dioxide and fly ash through a chemical reaction. After contact, the lime slurry drains into the recycle tank where it can be reintroduced back into the sulfur dioxide and fly ash removal process. A bleed stream controls the buildup of suspended solids in the recycle tank by continuously removing the solids and transferring it to lined disposal ponds. In the disposal ponds, the solids settle out and form a sludge. The supernatant water in the ponds is returned to the scrubbers for reuse.
