POLLUTION CONTROL EQUIPMENT SCRUBBER SYSTEM The air pollution control facilties employed on Units #3 and #4 consist of a complete scrubber system, including duct work, plenums, scrubber vessels, reheaters and induced draft fans, together with infrastructures, monitoring and electrical controls and instrumentation therefore, for the purpose of removing the sulfur dioxide (S02) and particulate matter from the flue gas. The scrubber system also includes a scrubber maintenance facilty, including a machine shop and laboratory dedicated to the scrubber system and an environmental monitonng laboratory for the pollution control facilities. The scrubber system utilizes the Wet Ventun Principle and consists of eight modules for each unit through which the steam generator gases from the burned coal must pass. The gases in the scrubber are contacted with finely atomized scrubber slurry. Within the stated perfonnance of the system, fly ash partculates are removed by the slurry droplets. The sulfur dioxide reacts with the alkali contained in the slurr which results from the mixing of water, fly ash particulates, hydrated high calcium lime and hydrated dolomitic lime. A major portion of the sulfur dioxide is converted to solid sulfate compounds which are retained in the scrubber liquid and can, therefore, be piped to and deposited in an ash pond together with the particulate. Mter the flue gas passes through the venturi section, absorption sprays and wash trays, it is processed through a demister which removes any entrained slurr and is then reheated and discharged through the stack. The slurr system in the Units #3 and #4 scrubber system consists of recycle tanks, regenerators, agitators, pumps and pipelines. The slurr from the Units #3 and #4 scrubber system is transported to an effluent holding pond and involves the use of effluent holding tanks, agitators, pumps and pipelines. A separate wash tray pond system is used to store the suspended solids collected from the wash tray system. Reclaimed water from the clear water section of these ponds is circulated back to the scrubber system. LIME STORAGE The sole purpse of the lime system is to supply the lie slurry requirements of the scrubber regeneration system. There is one lime system that serves the sixteen scrubbers for Units #3 and #4. Major components of the system include four slakers, in which calcined high calcium lime is reacted with water to produce a hydrated lime slurry, slurr transfer tanks, where the slurr is diluted with water and mixed with dry hydrated dolomitic lime, slurry feed storage A-I Series 200 Lo Agrement tanks, where the slurr wil be held for use by the regenerators as needed, hydrators, for mixing calcined dolomitic lime with water, and agitators. SCRUBBER SLUDGE DISPOSAL Effluent slurr is pumped from the plant to the sludge disposal pond located approximately three miles southeast of the plant. The suspended solids settle to the pond bottom and the clear water is pumped back to the plant. There are two phases in the development of this pond. The first phase requires the construction of one dam 108 feet high and 1,100 feet in length. A saddle dam must also be added. The saddle dam wil vary in height with a maximum height for this phase of 36 feet and be approximately 2,800 feet in lengt. The capacity of Phase i wìl be 6,650 acre-feet and it wil last approximately 10 years. The development of the second phase wil require that the onginal dam be raised to 138 feet in height and increased to a length of 2,500 feet. The saddle dam wil be raised to a maximum height of 66 feet and a total lengt of 3,500 feet. The capacity of the second phase wil be an additional 7,00 acre-feet and it wil last approximately 12 years, for a total life of 22 years. The construction of the second phase is not included in cost reported at this time. The sludge disposal pond design takes into account a permit requirement for minimum seepage, by providing low permeabilty plastic concrete filled trenches around the penphery of the pond constructed during the course of Phase 1 work. COAL DUST CONTROL SYSTEM The coal dust control system is designed to collect, store and treat coal dust resulting from mining, crushing, handling and storing coal in the course of normal Units #3 and #4 operations. To control coal dust air pollution the points where coal is transferred between conveyors or placed in coal piles have been enclosed. The coal transfer stations between conveyors are enclosed with steel framed strctures with metal siding. The structures are equipped with vacuum filtration systems, consisting of ducts, blowers, dust removal filters and associated equipment, to remove coal dust from exhaust air from the structures, and are also equipped with mechanical dust collectors. The main line 45,00 ton coal storage pile is enclosed with a 340' long A-frame precast panel concrete structure designed to contain coal dust, thereby allowing its removal and treatment. COOLING TOWER DRIFT CONTAINMENT CONTROL FACILIT Operation of the cooling towers produces exhaust air emissions containing circulating water, particulates and other pollutants generally known as cooling tower drift. To control release of these air pollutants, the cooling towers are provided with high effciency drift eliminators, located at the top of the cooling tower strctures, which remove drift from the cooling tower exhaust air. A-2 Series 2010B Loan Agrenint 2. SOLID WASTE DISPOSAL BOTTOM ASH DISPOSAL The function of the bottom ash disposal system is to remove accumulations of furnace bottom ash, pulverizer pyrites, economizer ash, and air preheater fly ash by means of a water-ash slurr to a disposal pond located approximately 2,00 feet southeast of the plant site. The system consists generally of three sets of fly ash hoppers, (economizer. air heater, and flue gas duct hoppers) pynte hoppers, the bottom ash hopper, and 18,00 gallon transfer tank, a settling pond, a clear water pond and vanous pumps, and pipelines. Clinker grinders are used to grind the bottom ash which is then mixed with water and sluiced to the ash transfer tank. The economizer ash collected in economizer hoppers falls by gravity to the ash transfer tank. The pyrites are collected in local tanks and sluiced to the ash transfer tank. Ash collected in the flue gas duct hoppers and air preheater hoppers is sluiced to the ash transfer tank. These ashes are pumped from the ash transfer tank to the bottom ash pond. Reclaimed water is returned from the bottom ash disposal pond and redistributed to the various sections of the bottom ash disposal system. The solid waste disposal facilities for purpses of the issuance of the Bonds include only so much of the bottom ash disposal system as is external to the plant building and include piping from the building to the settling pond, the pond itself, return water pumps and lines, a clear water pond and piping back to the plant building. 3 . WATER POLLUTION CONTROL NORTH PlNT SEDIMENT POND The nort plant sediment pond is designed to collect and store the storm runoff from the general north plant area. These waters are retained in the pond, allowing natural evaporation to desiccate the pond. This prevents high quantities of suspended solids from being discharged to Armells Creek or other state suiface waters. NORTH PlNT AREA DRAINAGE SYSTEM The north plant area drainage system is designed to collect and store storm runoff from the water treatment building. fuel oil handling area and the cooling tower area in the north plant area drain pond. The pond also serves as a storage facility for one cooling tower basin drain. A-3 Series 20108 Lon Agreement cooling tower overfow, water treatment fiter backwash, and for the cooling tower blowdown water not used in the flue gas scrubbing process. These waters are potentially contaminated with oil and high suspended and dissolved solids, and this system stores these discharges preventing any discharge to Armells Creek or other state surface waters. The north plant area drainage system consists of collection basins, piping, concrete culverts, yard drains, manholes and special yard gradings (berms) which route these discharges to the nort plant area sump and north plant area drain pond. The north plant area drain pond incorporates a hypalon liner to comply with a permit requirement for minimum seepage. The oil separator section of the sump receives oily surface collection drains. The oil and water are separated. The oil from the sump is then trucked away for disposal. The water discharges are either pumped to the scrubber effuent holding pond via a 6" diameter pipeline, 19,00 feet in length for evaporation, to the circulating water system, or the plant oily waste sump as appropriate. Each discharge arrangement has its own set of sump pumps. The pumps and piping system which discharge to the plant oily waste sump are not included in the costs covered by this Report, nor is the circulating water system. The waters recovered are excess to any plant requirements and recovery of the waters does not provide any economic benefit to the plant. CHEMICAL AND OILY WASTE SYSTEM The chemical and oily waste system is designed to collect, store, treat and dispose of chemical and oily wastes resulting from the normal operation of Units #3 and #4. This system consists of drains and pipes, oil separators, chemical waste sumps, chemical waste neutralizing tanks, neutralizing chemical storage tanks, chemical inspection equipment, and associated mechanical and electrical control equipment. The chemical waste drainage system includes drains and neutralization tanks for collection and tratment of chemical waste Chemical waste drains are located throughout Units #3 and #4, and are used to collect and transfer chemical waste to holding sumps and neutralization tanks. The neutralization equipment includes chemical storage and injection equipment as well as controls and instrumentation. The oily waste drainage system is made up of a network of drains which collect oily waste from throughout Units #3 and #4, and dispose of the wastes in the Units #3 and #4 main water-oil sump. Oil separation chambers in the sump allow for oil removaL. The treated water is monitored for trace oil levels and released. After separation, the waste oil is removed by a contractor to an offsite disposal area. COOLING TOWER BLOWDOWN SYSTEM The cooling tower blow down system consists of a 6" pipeline from the cooling tower tothe waste disposal pond where the blowdown is treated by settlement and evaporation in accordance with water pollution control requirements. A-4 Series 20lOB Loan Agreement GROUNDWATER MONITORING WELLS Groundwater monitoring wells have been installed around the various ponds associated with the plant operation. These ponds include the scrubber effluent holding pond, the scrubber drain pond, the scrubber wash tray pond, the bottom ash pond, and the nort plant area effuent pond. These groundwater monitonng wells provide the ability through sampling to detect and quantify accidental discharges from the above mentioned plant storage and waste ponds. This is necessary to show compliance with State Groundwater Standards and with permt requirements for minimum seepage.

CITY OF FORSYTH. MONTANA By: Mayor (SEAL) ATlEST: By: City Clerk-Treasurer A VISTA CORPORATION - 24-Series 20 lOA Lmin Agreement EXHIBIT A PROJECT DESCRIPTION 1. POLLUTION CONTROL EQUIPMENT SCRUBBER SYSTE The air pollution contrl facilties employed on Units #3 and #4 consist of a complete scrubber system, including duct work, plenums, scrubber vessels, reheaters and induced draft fans, together with infrastructures, monitonng and electncal controls and instrumentation therefore, for the purpse of removing the sulfur dioxide (S02) and partculate matter from the flue gas. The scrubber system also includes a scrubber maintenance facility, including a machine shop and laboratory dedicated to the scrubber system and an environmental monitoring laboratory for the pollution control facilities. The scrubber system utilzes the Wet Ventun Prnciple and consists of eight modules for each unit through which the steam generator gases from the burned coal must pass. The gases in the scrubber are contacted with finely atomized scrubber slurr. Within the stated performance of the system, fly ash parculates are removed by the slurry droplets. The sulfur dioxide reacts with the alkali contained in the slurry which results from the mixing of water, fly ash pariculates, hydrated high calcium lime and hydrated dolomitic lime. A major portion of the sulfur dioxide is converted to solid sulfate compounds which are retained in the scrubber liquid and can, therefore, be piped to and deposited in an ash pond together with the parculate. After the flue gas passes through the ventun section, absorption sprays and wash trays, it is processed through a demister which removes any entrained slurr and is then reheated and discharged through the stack. The slurry system in the Units #3 and #4 scrubber system consists of recycle tanks, regenerators, agitators, pumps and pipelines. The slurry from the Units #3 and #4 scrubber system is transported to an effuent holding pond and involves the use of effuent holding tanks, agitators, pumps and pipelines. A separate wash tray pond system is used to store the suspended solids collected from the wash tray system. Reclaimed water from the clear water section of these ponds is circulated back to the scrubber system. LIME STORAGE The sole purpose of the lime system is to supply the lie slurr requirements of the scrubber regeneration system. There is one lime system that serves the sixteen scrubbers for Units #3 and #4. Major components of the system include four slakers, in which calcined high calcium lime is reacted with water to produce a hydrated lime slurr, slurr transfer tanks, where the slurr is diluted with water and mixed with dry hydrated dolomitic lime, slurr feed storage A-I Series 200 Loa Agrment tanks, where the slurr wil be held for use by the regenerators as needed, hydrators, for mixing calcined dolomitic lime with water, and agitators. SCRUBBER SLUDGE DISPOSAL Effluent slurr is pumped from the plant to the sludge disposal pond located approximately three miles southeast of the plant. The suspended solids settle to the pond bottom and the clear water is pumped back to the plant. There are two phases in the development of this pond. The first phase requires the construction of one dam 108 feet high and 1,100 feet in length. A saddle dam must also be added. The saddle dam wil vary in height with a maximum height for this phase of 36 feet and be approximately 2,800 feet in length. The capacity of Phase 1 wil be 6,650 acre-feet and it wil last approximately 10 years. The development of the second phase wil require that the original dam be raised to 138 feet in height and increased to a length of 2,500 feet. The saddle dam wil be raised to a maximum height of 66 feet and a total length of 3,500 feet. The capacity of the second phase wil be an additional 7,00 acre-feet and it wil last approximately 12 years, for a total life of 22 years. The construction of the second phase is not included in cost reported at this time. The sludge disposal pond design takes into account a permit requirement for minimum seepage, by providing low permeabilty plastic concrete filled trenches around the periphery of the pond constructed during the course of Phase 1 work. COAL DUST CONTROL SYSTEM The coal dust control system is designed to collect, store and treat coal dust resulting from mining, crushing, handling and storing coal in the course of normal Units #3 and #4 operations. To control coal dust air pollution the points where coal is transferred between conveyors or placed in coal piles have been enclosed. The coal transfer stations between conveyors are enclosed with steel framed strctures with metal siding. The structures are equipped with vacuum fitration systems, consisting of ducts, blowers, dust removal fiters and associated equipment, to remove coal dust from exhaust air from the structures, and are also equipped with mechanical dust collectors. The main line 45,00 ton coal storage pile is enclosed with a 340' long A-frame precast panel concrete structure designed to contain coal dust, thereby allowing its removal and treatment. COOLING TOWER DRIFT CONTAINMENT CONTROL FACILIY Operation of the cooling towers produces exhaust air emissions containing circulating water, particulates and other pollutants generally known as cooling tower drift. To control release of these air pollutants, the cooling towers are provided with high effciency drift eliminators, located at the top of the cooling tower strctures, which remove drift from the cooling tower exhaust air. A-2 Series ZOlOA Lon Agreement 2. SOLID WASTE DISPOSAL BOTI'OM ASH DISPOSAL The function of the bottom ash disposal system is to remove accumulations of furnace bottom ash, pulverizer pyntes, economizer ash, and air preheater fly ash by means of a water-ash slurry to a disposal pond located approximately 2,00 feet southeast of the plant site. The system consists generally of three sets of fly ash hoppers, (economizer, air heater, and flue gas duct hoppers) pyrite hoppers, the bottom ash hopper, and 18,00 gallon transfer tank, a setting pond, a clear water pond and vanous pumps, and pipelines. Clinker grinders are used to grind the bottom ash which is then mixed with water and sluiced to the ash transfer tank. tank. The economizer ash collected in economizer hoppers falls by gravity to the ash transfer The pyntes are collected in local tanks and sluiced to the ash transfer tank. Ash collected in the flue gas duct hoppers and air preheater hoppers is sluiced to the ash transfer tank. These ashes are pumped from the ash transfer tank to the bottom ash pond. Reclaimed water is returned from the bottom ash disposal pond and redistnbuted to the vanous sections of the bottom ash disposal system. The solid waste disposal facilities for purpses of the issuance of the Bonds include only so much of the bottom ash disposal system as is external to the plant building and include piping from the building to the settling pond, the pond itself, return water pumps and lines, a clear water pond and piping back to the plant building. 3. W ATERPoLLtHION CONTROL NORTH PlANT SEDIMENT POND The north plant sediment pond is designed to collect and store the storm runoff from the general north plant area. These waters are retained in the pond, allowing natural evaporation to desiccate the pond. This prevents high quantities of suspended solids from being discharged to Armells Creek or other state surface waters. NORTH PlNT AREA DRAINAGE SYSTEM The north plant area drainage system is designed to collect and store storm runoff from the water treatment building, fuel oil handling area and the cooling tower area in the north plant area drain pond. The pond also serves as a storage facilty for one coolìng tower basin drain, A-3 Seres 20lOA Lo Agreement cooling tower overfow, water treatment fiter backwash, and for the cooling tower blow down water not used in the flue gas scrubbing proess. These waters are potentially contaminated with oil and high suspended and dissolved solids, and this system stores these discharges preventing any discharge to Armells Creek or other state surface waters. The north plant area drainage system consists of collection basins, piping, concrete culvert, yard drains, manholes and special yard gradings (berms) which route these discharges to the north plant area sump and north plant area drain pond. The north plant area drain pond incorporates a hypalon liner to comply with a permit requirement for minimum seepage. The oil separator section of the sump receives oily surface collection drains. The oil and water are separated. The oil from the sump is then trucked away for disposaL. The water discharges are either pumped to the scrubber effluent holding pond via a 6" diameter pipeline, 19,00 feet in length for evaporation, to the circulating water system, or the plant oily waste sump as appropriate. Each discharge arrngement has its own set of sump pumps. The pumps and piping system which discharge to the plant oily waste sump are not included in the costs covered by this Report, nor is the circulating water system. The waters recovered are excess to any plant requirements and recovery of the waters does not provide any economic benefit to the plant. CHEMICAL AND OILY WASTE SYSTEM The chemical and oily waste system is designed to collect, store, treat and dispose of chemical and oiJy wastes resulting from the normal operation of Units #3 and #4. This system consists of drains and pipes, oil separators, chemical waste sumps, chemical waste neutralizing tanks, neutralizing chemical storage tanks, chemical inspection equipment, and associated mechanical and electrical control equipment. The chemical waste drainage system includes drains and neutralization tanks for collection and treatment of chemical waste Chemical waste drains are located throughout Units #3 and #4, and are used to collect and transfer chemical waste to holding sumps and neutralization tanks. The neutralization equipment includes chemical storage and injection equipment as well as controls and instrumentation. The oily waste drainage system is made up of a network of drains which collect oily waste from throughout Units #3 and #4, and dispose of the wastes in the Units #3 and #4 main water-oil sump. Oil separation chambers in the sump allow for oil removaL. The treated water is monitored for trace oil levels and released. After separation, the waste oil is removed by a contractor to an offsite disposal area. COOLING TOWER BLOWDOWN SYSTEM The cooling tower blowdown system consists of a 6" pipeline from the cooling tower to the waste disposal pond where the blowdown is treated by settlement and evaporation in accordance with water pollution control requirements. A-4 Series 20JOA Lo Agrment GROUNDWATER MONITORING WELLS Groundwater monitoring wells have been installed around the various ponds associated with the plant operation. These ponds include the scrubber effuent holding pond, the scrubber drain pond, the scrubber wash tray pond, the bottom ash pond, and the north plant area effuent pond. These groundwater monitoring wells provide the ability through sampling to detect and quantify accidental discharges from the above mentioned plant storage and waste ponds. This is necessary to show compliance with State Groundwater Standards and with permit requirements for minimum seepage. A-5 Series 2010A Lon Agreement QC r:r.

In the event such Available Moneys are (a) not so received, (b) no longer sufficient to pay the principal of, and premium, if any, and interest on, such Bonds or (c) no longer considered Available Moneys, in each case, on the redemption date; the redemption shall not be made and the Trustee shall within a reasonable time thereafter give A-9 Series 2OIOA Trust Indenture notice, in the manner in which the notice of redemption was given, that such redemption wil not take place. If less than all of the Bonds are called for redemption, the Trustee shall select the Bonds or any given portion thereof from the outstanding Bonds or such given portion thereof not previously called for redemption, by lot. For the purpose of any such selection the Trustee shall assign a separate number for each minimum Authorized Denomination of each Bond of a denomination of more than such minimum; provided that, following any such selection, both the porton of such Bond to be redeemed and the portion remaining shall be in Authorized Denominations. Notwithstanding the foregoing provisions, Pledged Bonds shall be redeemed prior to any other Bonds.
