3. Facility description

Benson Power, LLC (Benson Power), located in Benson, Minnesota, owns and operates a single power boiler (EQUI001) with a design gross generating capacity of 65 MW and a maximum heat input of 792 MMBtu/hr. EQUI001 commenced operating February 18, 2007 and is a conventional stoker boiler that combusts solid biomass including turkey litter and secondary vegetative biomass. Propane is used as an ignition fuel. Emissions from EQUI001 are controlled by selective non-catalytic reduction (SNCR) using urea injection to reduce nitrogen oxides (NOx), a lime slurry injection scrubber spray-dry absorber (SDA) to reduce sulfur dioxide (SO2) and hydrochloric acid (HCL), and a fabric filter to reduce particulate matter (PM). Emissions exit via a 300 foot exhaust stack. Emissions from the boiler are monitored by a collection of continuous emission monitors (CEMS) for NOx, SO2, carbon monoxide (CO), carbon dioxide (CO2), opacity, oxygen (O2) on a wet and dry basis, and flow.

5.1.2 The following odor control measures shall be followed: 1. All poultry litter shall be processed, handled, and stored indoors. The building used for processing, handling, and storage of poultry litter shall be tightly closed, and ventilated so that all air, gases, and air or gas-borne material are treated by incineration or other effective means before discharge into the open air. 2. Poultry litter delivery trucks arriving at the facility will be covered. Trucks used to deliver poultry litter to the facility will be clearly marked and identified so that any problems with particular trucks can be recognized and quickly resolved. 3. The number of doors open at any given time will be a function of the overall volumetric flow of air from the fuel receipt and storage area. The number of doors open at any one time will be based on the criteria established in a report that determines the number of doors that can be open during specific operation scenarios. This report can be found in Appendix E. 4. Poultry litter delivery trucks will be washed prior to leaving the facility. 5. At least once per day, a site odor assessment shall be performed. The odor assessment will include site inspection to monitor housekeeping practices, operating procedures, and will include site perimeter walks. Records, including the presence of odors, will be maintained documenting each site inspection. 6. If there exists the presence of odors, immediate steps will be taken to determine the source of the odors, and corrective action shall be taken. Records shall be kept documenting the source of the odors, and the corrective action taken. 7. If the daily site odor assessment is performed for 30 consecutive days after initial startup, and problematic odors are not detected, the site odor assessment may be performed once per week. 8. The Permittee shall have a designated staff person responsible for taking phone complaints from neighboring residences and businesses. The name or title of the staff person shall be made publicly available, as well as the appropriate phone number to call.

1 Plan Purpose The Fugitive Dust Control Plan identifies control measures and practices to minimize and control fugitive dust from the biomass power plant operation. The plan defines:

• The Practices plant personnel will follow to control emissions; • The levels of visible emissions requiring corrective actions; • Steps that will be followed to bring emissions within appropriate ranges; and • Recordkeeping and Reporting procedures for routine inspections and corrective actions.

To meet these objectives, the Fugitive Dust Control Plan:

• Identifies major fugitive emission sources within the plant operations; • Identifies the control measures and practices to control and minimize fugitive emissions.

• Identifies visible emission observation and corrective action requirements. • Describes fugitive dust control training elements. • Identifies fugitive dust control recordkeeping requirements.

2 Introduction On August 19, 2015, Benson Power, LLC (Benson Power) purchased the assets of Fibrominn, LLC out of receivership. The assets included a nominal 65-MW biomass power plant, located at 900 Industry Drive in Benson, a city in Swift County, Minnesota. Formerly called the Fibrominn Biomass Power Plant, the plant is now the Benson Biomass Power Plant, referred to here as the Facility. The present document is Benson Power’s proposed update of the Fugitive Emissions Control Plan for the Facility. The Facility has been in operation since its initial start-up in 2007. Historically, the Facility had been fueled principally with poultry litter (turkey and chicken litter), comprised of a mixture of poultry droppings and cellulosic poultry-barn bedding material, typically wood shavings. Vegetative biomass (primarily wood chips) serves as the secondary fuel. Recently, the poultry litter fraction has been in the 30% to 40% range. The Facility is permitted to combust poultry litter and vegetative biomass fuels in any relative fractions up to 100% litter or 100% vegetative biomass. At the Facility, all poultry litter is delivered in covered trucks and stored within an enclosed fuel storage building prior to combustion. No litter is stored outside the fuel storage buildingl. Wood chips are similarly delivered in covered trucks. While most wood chip deliveries are made directly to the enclosed fuel storage building, some are directed to an on-premises, outdoor storage area, where the wood chips are stored temporarily in uncovered piles in a designated area. Fuel is combusted at the Facility in a conventional spreader-stoker boiler. A conventional steam turbine-generator produces electric power which is sold to a public utility company. The Facility’s boiler is cooled using an air-cooled condenser. The ash produced at the Facility from the combustion of poultry litter contains agronomic nutrients and is marketed as a fertilizer product under a case-specific beneficial use determination received from the MPCA on May 24, 2004. The Facility delivers its combined ash stream, via an enclosed conveyor, to an adjacent facility independently owned and operated by North American Fertilizer (NAF). At the NAF facility, the ash is conditioned (moistened), stored, and loaded into trucks within two (2), totally-enclosed warehouse buildings, then shipped via covered trucks to regional fertilizer markets. While the NAF facility is not on the Facility property, ort owned or operated by, or affiliated with Benson


Power, the NAF facility is considered a “support facility” by MPCA. A 2009 Stipulation Agreement between the former owners and the MPCA, required that emissions from NAF be incorporated into a major source permit amendment. Applicable Fugitive Particulate Matter Control Requirements (Permit Driven) In Facility permit 15100038-004, three (3) permit conditions exist on page A-2 that address the general requirements to control fugitive particulate matter emissions and to submit and comply with a Fugitive Emissions Control Plan. Condition 1, pg. A-2 (Internal Identification as A.2.5.1) [Minn. R. 7011.0150] Fugitive Emissions: Do no cause or permit the handling, use, transporting, or storage of any material in a manner which may allow avoidable amounts of particulate matter to become airborne. Comply with all other requirements listed in Minn. R. 7011.0150. Condition 2, pg. A-2 (Internal Identification as A.2.5.2) [Minn. Stat. Section 116.07, subd. 4a; Minn. R. 7007.0800, subp. 2] Fugitive Emissions Control Plan: The Permittee shall submit a fugitive emissions control plan within 60 days of the date of permit issuance for review and approval by the Commissioner. The plan shall identify all fugitive emission sources, primary and contingent control measures, and record keeping. The Permittee shall follow the actions and record keeping specified in the control plan. The plan may be amended by the Permittee with the Commissioner’s approval. If the Commissioner determines the permittee is out of compliance with Minn. R. 7011.0150 or the fugitive emission control plan, then the permittee may be required to amend the control plan and/or install and operate particulate matter ambient monitors. Condition 3, pg. A-2 (Internal Identification as A.2.5.3) [Minn. Stat. Section 116.07, subd. 4a; Minn. R. 7007.0800, subp. 2] Comply with Fugitive Emission Control Plan: The Permittee shall follow the actions and record keeping specified in the control plan. The plan may be amended by the Permittee with the Commissioner’s approval. If the Commissioner determines the permittee is out of compliance with Minn. R. 7011.0150 or the fugitive emission control plan, then the Permittee may be required to amend the control plan and/or to install and operate particulate matter ambient monitors as requested by the Commissioner. As a matter of practice the Facility will routinely address the following Minnesota Regulations (Minn. R.) and practices as described: Per Minn. R. 7011.0150; Minn. R. 7007.0800, subp. 2, The facility shall take reasonable measures to prevent particulate matter from becoming airborne. During each week of operation the Permittee shall visually inspect all paved surfaces to minimize or eliminate fugitive emissions. The facility shall maintain a record of this inspection that includes the date of the inspection, whether fugitive dust was observed, what corrective actions were taken, when the corrective actions were taken, and whether the corrective actions eliminated the fugitive dust. 3 Identification of Potential Sources of Fugitive Dust The Facility operations are conducted primarily within enclosed buildings. The potential sources of site-derived fugitive dust are generally related to locations where fuel is received, stored, and processed as well as where the ash by-product is stored, processed, and transported from the site.


3.1 The following potential sources exist: 3.1.1 (EQUI 005) Fuel Handling and Storage The transport and delivery of fuel on site could be a source of fugitive dust. Upon arrival at the Facility, poultry litter and wood chip delivery trucks back into the fuel receipt area, which is within the enclosed, fuel receipt and storage building. The fuel receiving area of the building is maintained under negative air pressure, such that air is drawn into the building as doors open to admit fuel delivery trucks. That air is drawn into the boiler where it is used as combustion air, hence, thermally destroying the dust and odors present in that air. The fuel storage area could be a source of fugitive dust. After delivery to the fuel storage building, the fuel (poultry litter and wood chips) is blended using an overhead crane, which lifts and distributes fuel; this movement may cause fugitive dust within the building. The fuel is then “de-lumped” within the building via mechanical processing equipment, which is an enclosed process during and up until placement on the fuel belt. The prepared fuel is transported from the fuel storage building to the boiler building by an enclosed conveyor system. This conveyor system delivers the fuel to the fuel feed bins at the boiler face, and could be a minor source of fugitive dust in the boiler building. There are times when operations are reduced or discontinued because of curtailment or plant maintenance. The Facility is uniquely designed for such instances, as the Facility includes a back-up odor and dust control system for the fuel-receipt and storage building. This back-up system can operate either in conjunction with the primary dust/odor controls; i.e., the “negative air” combustion air system, or alone when combustion operations are discontinued. While the back-up odor and dust control system is specifically designed to minimize the release of fugitive dust, this system also is a potential source of fugitive dust emissions in the event of a system failure. Mitigation measures would be taken, e.g. limitation of fuel movement and transfer during these times. 3.1.2 (EQUI 012) Uncaptured Dust Emissions from Ash Handling (Conveyors) Ash from the combustion process is collected from three (3) distinct steps in the process: (1) bottom ash from the furnace and grate, (2) heat transfer back-pass ash prior to the air pollution control system, and (3) entrained ash from the spray dryer absorber and fabric filter baghouse. Bottom ash is further processed (crushed) for size reduction within the boiler building for ease of transport. The boiler building could also be a source of fugitive dust associated with ash collection and bottom ash processing. Any dust from this process is captured via the TREA 002 Fabric Filter control and is then combined with fly ash for conveyance to NAF. After collection and combination of ash in enclosed material transport systems, the three ash streams (fly ash, grate ash, super heat ash) are then conveyed via an enclosed conveyor system to the adjacent, ash processing and storage building. 3.1.3 (EQUI 013) Alternate Ash Collection System (Chute Drop to Portable Dumpsters) The ash conveyance system could also be a source of fugitive dust in the event of a break in a seal or deterioration of expansion joint in the system. These systems are routinely monitored and inspected to ensure fugitive emissions are kept to a minimum from these events. A small quantity of ash is transferred via diverter chutes to enclosed dumpsters that are trucked to NAF. This occurs only when the conveyor system is out of service, or during scheduled maintenance outages (typically semi-annually) at the Facility when the flue grate is rinsed.


3.1.4 NAF Ash Building There are two buildings at NAF that manage ash and have vents with insignificant sources of emissions. The North Ash Building has two vents, one the North Vent is equipped with a wet venturi scrubber. The South Ash Building has one vent, known as the East Vent, which is equipped with a dry venturi scrubber. While Benson Power does not own or operate the real property of NAF or the NAF company, we understand that its operations take place within the enclosed buildings. 3.1.5 (EQUI 004) Lime Storage Silo. Lime is utilized in the spray dryer absorber for acid gas reduction. Lime is stored in a silo in close proximity to the spray dryer absorber. The transfer of lime from delivery trucks to the silo, the conveyance of lime to the lime slaking equipment, and preparation of the lime slurry for use in the spray dryer absorber is a potential source of fugitive dust. 3.1.6 (FUGI 003) Outdoor fuel storage area (wood chip storage only). There are two outdoor wood-chip storage piles which may contribute to fugitive emissions from materials handling and wind erosion. 3.1.7 (FUGI 004) Site Roadways. The site roads used by fuel delivery trucks, trucks delivering other supplies, ash transport trucks, as well as employee and visitor vehicles, are all paved. Parking lots at both facilities are also paved. Undeveloped areas of the site remain in their natural, undisturbed form. Developed areas of the site are planted and maintained. Both the transport roads and the site grounds are potential sources of fugitive dust, however; such dust would be incidental to facility operations and likely (in the case of paved roads) as a result fugitive emissions from offsite sources (contiguous sources including local agricultural operations). 4 Control Measures Implemented for Fugitive Dust Emissions For each of the process-related potential sources of fugitive dust emissions, this plan explains the design and operating aspects of the Facility that are associated with the reduction in fugitive dust emissions. As described above, the odor prevention measures mandated by the permit for the fuel building also control fugitive dust. As part of the site odor prevention permit conditions, the facility has agreed to indoor processing, handling, and storage of poultry litter. 4.1 General Site Access and Control To support overall dust control and to limit access by non-plant personnel to fugitive operations, the following controlled access to facility premises will be employed. Facility fencing is proposed to identify all contiguous property for the plant; Where facility fencing is not feasible, e.g. the adjacent wetlands to the property, these areas will be clearly posted and marked as private property and will be patrolled by plant operations personnel to ensure no public access per EPA 1/30/87 USEPA Memo Ambient Air. Limited vehicular access to the site via controlled gate access and monitoring of fuel delivery trucks/personnel by fuel management process/system.


4.2 The following potential sources exist: 4.2.1 (EQUI 005) Fuel Handling and Storage

4.2.1.1 Fuel Delivery As required by the Facility’s Title V air permit, poultry litter transport must be in covered trucks (i.e. “sheeted” trailers). Also, by permit, the poultry litter delivery trucks must be washed prior to leaving the site after emptying their loads within the fuel receiving and storage building. Permit Condition, pg. A-3 (Internal Identification as A.3.7.3) [Minn. R. 7007.0800, subp. 2] Poultry litter delivery trucks arriving at the facility will be covered. Trucks used to deliver poultry litter to the facility will be clearly marked and identified so that any problems with a particular vehicle can be recognized and quickly resolved. Permit Condition, pg. A-3 (Internal Identification as A.3.7.5) [Minn. R. 7007.0800, subp. 2] To further avoid the release of fugitive dust emissions from the poultry-litter delivery trucks, sheeting curtains are maintained in place until the truck has backed through the open door into the receiving bay of the fuel receiving and storage building. Covered truck trailers prevent the release of dust associated with transport of the poultry litter to the Facility. Fuel is then unloaded from the trucks into receiving pits. The sheeting materials, in combination with appropriate housekeeping practices, and negative air pressure in the fuel storage building helps to prevent fugitive dust associated with fuel receipt as trucks leave the fuel receipt and storage building. The trucks delivering fuel other than poultry litter (e.g., wood chips) to the Facility are also similarly sheeted, except when material is received baled or bound. As with poultry litter delivery trucks, deliveries of secondary biomass material are monitored by the Facility’s fuel-receipt personnel and corrective actions taken where necessary to avoid fugitive dust emissions associated with such fuel delivery. Fugitive dust emissions are minimized by restricting the number of doors open at the same time during offload operations. By maintaining negative pressure according to the above permit condition, the Facility minimizes the release of fugitive dust emissions from the fuel receipt area. By design, the source of primary air for combustion is air extracted from the fuel receipt and storage building. To maintain proper boiler operation, the Facility draws needed air through the periodically opened fuel truck delivery doors. By inducing airflow into the building when a door is open, this discourages dust-laden air from escaping outside the fuel building.. The fuel receipt and storage building includes spring-loaded louvers to provide required boiler combustion make-up air (based on a set differential pressure) for times when all the doors are closed (e.g.,. nighttime operations). The combination of air drawn through the open doors and the spring-loaded air intake louvers, results in a steady infiltration of air (i.e. “negative pressure”) into the building. The use of a negative pressure gradient is a proven means to minimize the release of odor from the fuel and likewise reduce the fugitive dust from the fuel receipt and storage building. The number of doors open at any given time will be a function of the overall volumetric flow of air from the fuel receipt and storage area. A report outlining the functions of the fuel receipt area doors was submitted on May 4, 2007 to MPCA, this report outlines the number of doors that can be open during specific operating scenarios. The number of doors open at any one time will be based on the criteria established in this report.


In addition, the fuel receipt and storage building is also designed to provide a barrier between the ambient air and the receipt and storage areas. The building utilizes two layers of architectural siding with internal insulation and a vapor barrier. While this construction is a means to avoid problems with corrosion (high moisture indoor atmosphere), it also results in containment of fugitive dust.

4.2.1.2 Fuel Storage All poultry litter shall be processed, handled, and stored indoors. The building used for processing, handling, and storage of poultry litter shall be tightly closed, and ventilated so that all air, gases, and air or gas-borne material are treated by incineration or other effective means before discharge into the open air. All secondary biomass materials delivered to the fuel receipt and storage building are stored and blended along with poultry litter. Fugitive dust emissions from the fuel storage and processing area is controlled by maintaining a negative pressure gradient and proper architectural siding design. Unlike in the fuel receipt area, door access to the fuel storage area is minimal. Access would typically be for purposes of building and equipment maintenance. Such doors are considered a part of the demonstration of proper volumetric flow into the building. 4.2.2 (EQUI 012) Uncaptured Dust Emissions from Ash Handling (Conveyors) In order to minimize the potential for uncaptured dust emissions from ash handling to enter the environment, the following activities will be taken on the enclosed conveyor system:

- Periodic inspections of and roper maintenance of wrapped insulation of conveyance system to ensure integrity of enclosure;

- Repairs and maintenance on the conveyor system will be conducted in a manner that will minimize ash emissions including but not limited to; conducting maintenance when plant is in shut-down operations where possible, with no ash being conveyed; or to expedite repairs when the plant remains in operation.

- Routine housekeeping in the areas surrounding, above, below and on the conveyors. 4.2.3 (EQUI 013) Alternate Ash Collection System (Chute Drop to Portable Dumpters) Two (2) alternate ash collection systems are utilized only when the main ash conveyance system is out of service. These are covered drop chutes connected to portable dumpsters and do not operate simultaneously with the main ash conveyance system to NAF. The following best management practices will be employed when (one or two times per year, typically during planned Facility shut downs for maintenance) these alternate chutes are utilized:

- Routine housekeeping in the areas surrounding, above, below and on the conveyors 4.2.4 NAF Ash Building All components of the ash-handling system at the NAF facility (ash collection, conditioning, storage, and truck out-loading) reportedly take place within enclosed structures to minimize the potential for fugitive dust emissions. These include ash conditioning, blending, storage, as well as ash truck-load out. There, ash is conditioned (moistened), minimizing the amount of airborne dust within the building, and this substantially reduces the potential for fugitive dust emissions


Truck transport of ash by-product from the adjacent NAF facility reportedly is in covered trailers. To avoid the tire-tracking of ash from the ash storage and handling building, ash is conditioned with water within the building prior to storage and load-out. Ash conditioning is a proven means to minimize the airborne concentration of dust within such a building. Ash conditioning minimizes the amount of airborne dust within the ash load-out area of the building, thereby minimizing fugitive dust release associated with off-site transport of the ash by-product. The sources at NAF are beyond the control of the Facility as they are owned and operated by NAF on private property. Benson Power cannot control or conduct BMPs on NAF property. A notification can be made to NAF based on concerns or observations that would warrant follow up by NAF. 4.2.5 (EQUI 004) Lime Storage Silo Pebble-lime reagent for the Facility’s acid gas scrubber is stored in a silo prior to use. The silo is fitted with a bin vent filter to avoid the escape of dust to ambient air during silo filling and emptying. The lime conveyor from the silo to the lime processing equipment is fully enclosed, minimizing the potential for fugitive dust emissions. The equipment for processing pebble lime into a lime slurry is operated in enclosed buildings, minimizing the potential for fugitive dust emissions. In addition the Facility: § Routinely inspects the area for visible traces of lime/lime dust. § Routinely inspects manual operation and status of magnahelic pressure gauge to verify operating condition of

filter media. § Conducts routine maintenance on filter media and silo to maintain integrity of the system.

4.2.6 (FUGI 003) Outdoor fuel storage area (wood chip storage only) § Woody biomass storage piles are managed on a first-in/first-out basis to minimize the accumulation of older

fuel. We address both piles and manage first in/first out. § Woody biomass storage areas are managed to avoid excessive wind erosion. The facility maintains two wood

piles. We pile incoming fuel into two wood piles orientated East/West as indicated by ERM to minimize emissions. There is also a paved center road to access the piles.

§ Mechanical moving of woody biomass by front end loaders and other supporting equipment shall be minimized on high wind event days. Mechanical moving will be conducted at grade level to minimize airborne dust, except as necessary to manage incoming material.

4.2.7 (FUGI 004) Site Roadways Fugitive dust emissions on site roadways is managed by the following control measures:

1. Reduced vehicle speed for all vehicular traffic entering the facility. 2. Utilization of a designated fuel roadway into the plant 3. Ground vegetation and plantings 4. Permanent paving or temporary non-erodible ground covering, such as mats or planking 5. Management of Fuel Delivery Trucks Exiting the Facility: Prior to departure from the fuel receipt area, fuel trucks

are again sheeted and proceed to the truck scale and truck wash area. The poultry litter delivery trucks are


washed prior to departure from the site (for biosecurity reasons), further reducing the potential for fugitive dust emissions related to transport operations.

4.3 Secondary Dust Control In addition to process-related fugitive-dust control measures, The Facility also utilizes secondary means to minimize fugitive dust emissions. Such secondary control measures are undertaken as an adjunct to meeting odor control requirements. As provided in the odor control section of the permit, the Facility monitors the site and operations for odor, including regular, site assessments to monitor housekeeping practices and operating procedures. The regular site assessments include site perimeter walks which are also used to monitor the site and site operations for fugitive dust emissions. Following are the permit conditions covering the site assessment for odor: Permit Conditions, pg. A-3 (Internal Identification as A.3.7.6, A.3.7.7, A.3.7.8) [Minn. R. 7007.0800, subp. 2] At least once per day, a site odor assessment shall be performed. The odor assessment will include site inspection to monitor housekeeping practices, operating procedures, and will include site perimeter walks. Records, including the presence of odors, will be maintained documenting each site inspection. If there exists the presence of odors, immediate steps will be taken to determine the source of the odors, and corrective action shall be taken. Records shall be kept documenting the source of the odors, and corrective action taken. If the daily site odor assessment is performed for 30 consecutive days after initial startup, and problematic odors are not detected, the site odor assessment may be performed once per week. Secondary dust control is based on the identification of items noted in inspections. Please see section 8 for information regarding the weekly inspections conducted at the facility. As such, as part of site inspections, the Facility looks at site housekeeping practices, operating procedures, and includes a site perimeter walk to determine if visible dust emissions are present at the property boundary. If fugitive dust emissions are observed, steps are taken to determine and document the source and corrective actions taken. 5 Recordkeeping Records are maintained and retained at the Facility as required by the permit. The fugitive dust emissions control plan is maintained on-site for review. In addition, the report justifying the number of doors that can be open during fuel unloading operations is maintained at the Facility. 6 Identifies fugitive dust control notification requirements

Semi-Annually the facility will report deviations of the permit conditions relating to fugitive dust control.

7 Describes fugitive dust control training elements Employees at the facility will be trained annually on the components of the fugitive dust control plan, including the inspection and permit requirements relating to controlling fugitive dust from operations.
