This plan includes CCR fugitive dust control measures that are most appropriate for site conditions, along with an explanation of how the measures selected are applicable and appropriate for site conditions. The Jim Bridger plant operates an ash landfill. This CCR fugitive dust control plan includes procedures to emplace CCR as conditioned CCR. 2.2 CCR units for this facility are described below: Jim Bridger Industrial Landfill FGD Pond FGD Pond Wash down and Decanting Basins (Terminal Structures T6 and T7) Short Haul Pad In addition to the listed CCR units, this fugitive dust control plan addresses activities associated with CCR loading, unloading and transport.

2 3.0 CCR FUGITIVE DUST CONTROL MEASURES: This section describes the measures utilized for the control of CCR fugitive dust emissions for each CCR rule-affected unit, road, and other CCR management and material handling activity at the facility. 1. Jim Bridger Industrial Landfill The landfill cells that are not active will be sealed to prevent fugitive dust emissions until visible emissions appear and then the area will be re-sealed. All vehicle traffic will be kept off the sealed area until the area becomes an active disposal cell. For the Jim Bridger Industrial Landfill, the following measures have been implemented to control fugitive dust emissions from the CCR unit: Fly ash and bottom ash are delivered to the ash landfill via haul truck. This CCR material is placed at the landfill in windrows at delivery. Bottom ash deposited at the landfill is moist to help prevent fugitive dust emissions. Water is applied to landfill-delivered fly ash as a compaction aid and for fugitive dust control during the loading of fly ash. As required, the windrows will be compacted and covered with bottom ash and/or sealant. The following action levels are utilized for the control of CCR fugitive dust emissions from the Jim Bridger Landfill. As required, the roads and active parts of the landfill are watered during non-freezing weather conditions except for rainy and snowy conditions. If dust control actions are determined not to be effective due to high wind events, operations of ash unloading and transport of ash will be curtailed until wind velocity subsides The Jim Bridger Industrial Landfill shall be inspected weekly for the presence of fugitive dust emissions by operations personnel. The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust from the Jim Bridger Industrial Landfill shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Outside Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions at the Jim Bridger Industrial Landfill, the on-duty Outside Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include using plant equipment to wet the source(s) of fugitive dust

3 emissions; applying a sealant or dust suppressant on the source of fugitive dust emissions; covering the source of fugitive dust with bottom ash or native soils, or utilizing other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the daily Operations Environmental Checklist. 2. Jim Bridger Industrial Landfill Haul Road to the Plant Truck Unloading Stations The following measures have been implemented to control CCR fugitive dust emissions from the Jim Bridger industrial landfill haul road. The haul road is treated with dust suppression chemicals by contractors. The road from the Mine Haul Road to the industrial landfill is watered as required during non-freezing weather conditions except for rainy and snowy conditions. In addition, bed liners have been installed in the haul trucks to dewater bottom ash received from the submerged drag chain conveyors. The majority of water entrained in plantgenerated bottom ash drains from the haul trucks into a concrete collection sump located at the loading area. Small amounts of water continue to drain from the haul trucks while the bottom ash is being transported to the landfill. Water draining from the haul trucks is used as supplemental dust control on the haul road. If dust control actions are determined to not be effective, ash haul vehicular activity on the affected ash haul road will be curtailed until conditions approve. Vehicle speed on the ash haul road shall be limited to a maximum velocity of 45 mph. The Jim Bridger Industrial Landfill Haul Road shall be inspected weekly for the presence of fugitive dust emissions. The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust to the Jim Bridger Industrial Landfill Haul Road from the Jim Bridger Plant property shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions from the Jim Bridger Plant to the Industrial Landfill Haul Road, the on-duty Outside Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include using plant equipment to wet the source(s) of fugitive dust emissions; applying a sealant or dust suppressant on the source of fugitive dust emissions; or utilizing other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the daily Operations Environmental Checklist.

4 3. FGD Pond 1 For flue gas desulfurization (FGD) Pond 1, the following measures have been implemented to control fugitive dust emissions from the CCR unit: FGD Pond 1 is currently in the closure process. There are dewatering trenches to remove as much liquid as possible prior to putting a cap seal on the pond. For the control of fugitive dust, those areas of FGD Pond 1 which have exposed CCR which has the potential to create fugitive dust emissions shall be reclaimed or treated with a chemical sealant/dust suppressant. FGD Pond 1 shall be inspected weekly for the presence of fugitive dust emissions, and dust control sealants or water shall be applied to any unclaimed dry areas as necessary for the purpose of preventing or controlling fugitive dust emissions. Dust control sealants will be applied as required to all pond areas which are potential sources of CCR fugitive dust emissions. The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust from FGD Pond 1 shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions at FGD Pond 1, the on-duty Outside Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include using plant equipment to apply a sealant or dust suppressant on the source of fugitive dust emissions; or other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the weekly Operations Environmental Checklist. 4. FGD Pond 2 For FGD Pond 2, the following measures have been implemented to control fugitive dust emissions from the CCR unit: For the control of fugitive dust, those areas of FGD Pond 2 which have exposed CCR which has the potential to create fugitive dust emissions shall be treated with water or a chemical sealant/dust suppressant. FGD Pond 2 shall be inspected weekly for the presence of fugitive dust emissions, and dust suppressant sealants or water shall be applied to areas which have the potential to emit CCR fugitive dust emissions, such as non-wetted shoreline surface areas with exposed CCR material.

5 The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust from FGD Pond 2 shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions at FGD Pond 2, the on-duty Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include using plant equipment to wet the source(s) of fugitive dust emissions; applying a sealant or dust suppressant on the source of fugitive dust emissions; or other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the weekly Operations Environmental Checklist. 5. Ash Unloading Areas Plant-generated bottom ash, and fly ash not for beneficial use, is transported to the Jim Bridger Industrial Landfill or Unit 1 FGD under closure via haul truck. Facility-generated fly ash not for beneficial use is loaded into haul trucks from the Units 1, 2, 3 and 4 fly ash silos. Fly ash stored in the silos is gravity-fed into fly ash unloaders which discharge into haul trucks. The fly ash unloaders mix water with the fly ash to condition the ash prior to loading into the haul trucks to prevent fugitive dust emissions during the fly ash loading and transport process. Fly ash loaded into the haul trucks is transported to the Jim Bridger Industrial landfill for disposal. Facility-generated fly ash for beneficial use is transported off-site from the Units 1-4 fly ash storage silos via haul truck and railcar. Plant-generated bottom ash is transported to one three sided concrete bunker with a partition wall (set up for two haul trucks) via a system of submerged drag chain conveyors (SDCCs). The primary destination / source of the bottom ash is the load out conveyor bunker. This is the three sided concrete bunker with the partition wall located at the north end of Unit 4. In addition, there is one bunker basin for Unit 1, a second bunker basin for Units 2 and 3, and a third bunker basin for Unit 4. Bottom ash from the SDCCs is discharged into the three bunker basins if the load out conveyor is not operational. Haul trucks are loaded at the load out conveyor structure during normal operations. The haul trucks transport the collected bottom ash to the Jim Bridger Industrial Landfill for disposal.

6 When the load out conveyor is out of service, heavy equipment front-end loaders are used to load the collected bottom ash from the three bunker basins into dump trucks. Boiler-generated bottom ash is a moist, course, non-dusting granular material which does not typically require additional dust control. The Jim Bridger Units 1-4 fly ash unloading/loading areas, including the truck and railcar loading areas, and the Unit 1, Units 2 and 3, and Unit 4 SDCC bottom ash bunker basins; and the load out conveyor bunkers shall be inspected weekly for the presence of fugitive dust emissions. The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust from the Jim Bridger fly ash and bottom ash collection and loading/unloading areas shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Outside Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions at the Units 1-4 fly ash unloading/loading areas or the Unit 1, Units 2 and 3, and Unit 4 SDCC bottom ash bunker basins, the on-duty Outside Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include wetting or sweeping the SDCC concrete bunker basins and/or Units 1-4 fly ash unloading areas, using plant equipment to wet the source(s) of fugitive dust emissions; applying a sealant or dust suppressant on the source of fugitive dust emissions; or utilizing other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the daily Operations Environmental Checklist. 6. Jim Bridger Power Plant Dust Control Schedule There will be a minimum of four applications per year of magnesium chloride dust suppressant to the unpaved trafficked areas of the plant, haul-roads, ash landfill, and FGD Pond 1 access road. The magnesium chloride is mixed to a 30-50% solution with water and applied at a rate of 0.5 gallons per square yard. The facility has two 10,000 gallon vehicles that are used for dust control watering of the unpaved areas at the Jim Bridger Plant. Dust sealants may also be applied to areas of the plant that are not trafficked, as required. 7. Wash down and Decanting Basins (Terminal Structures T6 and T7) The Jim Bridger wash down and decanting basins T6 and T7 collect all water from the plant drains, blowdown, and area run-off in the vicinity of the 01 effluent

7 pond. Any spillage of CCR material or CCR material collected in the plant waste streams, drains, or from runoff is routed to the T6 or T7 basins. The T7 basin collects any drainage from the ash unloading areas and area runoff from areas located north of the 01 effluent pond before decanting into the 01 effluent pond. The T6 basin collects water from all floor drains and blowdown liquids prior to decanting into the 01 effluent pond. Any CCR material from the influent will settle out in one of the two sections of the T6 basin which can be operated and cleaned independently of each other. The 01 effluent pond decanted liquids are pumped to the evaporation pond located north of the Jim Bridger Plant for final evaporation. The T6 and T7 basins will be inspected weekly for the presence of CCR dust emissions. The results of the weekly fugitive dust visual inspections shall be recorded on an Operations Environmental Checklist inspection log sheet. This log sheet shall identify the date of inspection as well as the name and employee number of the person conducting the weekly visual inspection. Any observations of CCR fugitive dust from the Jim Bridger T6 and T7 decanting basin area shall be recorded on the Operations Environmental Checklist log sheet. If visible CCR fugitive dust emissions are observed, the inspector shall immediately report the visible dust observation to the on-duty Outside Shift Supervisor. Upon receipt of notification of CCR fugitive dust emissions at the wash down and decanting basins, the on-duty Outside Shift Supervisor shall immediately initiate corrective actions to reduce and eliminate the source of emissions. Corrective actions may include using plant equipment to wet or wash down the source(s) of fugitive dust emissions; applying a sealant or dust suppressant on the source of fugitive dust emissions; or utilizing other actions as necessary to eliminate all sources of CCR fugitive dust emissions. Any corrective actions initiated to control fugitive dust emissions shall be documented and recorded on the daily Operations Environmental Checklist. The T6 and T7 wash down and decanting basins will contain water at most times, minimizing potential fugitive dust emissions. The basins will accumulate sludge and require periodic cleaning. CCR sludge from the T6 and T7 basins will be transported to the ash landfill for final disposal. 8. Short Haul Pad The Short Haul Pad is located directly south of Terminal Structure 6. The Short Haul Pad is a sloped concrete pad that is used to short haul CCR waste for temporary storage prior to disposal in the Ash Landfill. Sludge is hauled to the pad and any water will be decanted into Terminal Structure 6. The dewatered CCR waste can then be transferred to the Ash Landfill as needed. 4.0 CCR CITIZEN COMPLAINTS:
