1.2 Facility description

American Crystal Sugar - Moorhead is a sugar beet processing plant that produces granulated sugar, powdered sugar, brown sugar, molasses, and pelletized sugar beet pulp. The facility consists of three sub-bituminous coal-fired boilers, two natural gas or on-site generated biogas (anaerobic digester gas)-fired pulp dryers, three pulp pellet mills, one pulp pellet cooler, one vertical lime kiln, one sugar dryer, one sugar cooler, one emergency generator, wastewater treatment operations (including an anaerobic digester and equalization pond, each vented to a flare), material handling equipment and storage silos (for coal, sugar, beet pulp, and pellets), sugar packaging equipment, and fugitive material handling. The three sub-bituminous coal-fired boilers are each equipped with an oxygen trim system for the control of carbon monoxide emissions, three electrostatic precipitator (ESP) fields in series for the control of particulate emissions, and an activated carbon injection system for the control of mercury emissions. Each boiler is additionally equipped with a continuous opacity monitoring system (COMS), a steam flow meter, a flue gas oxygen analyzer, and an activated carbon injection rate meter. In addition to sub-bituminous coal, the boilers are each authorized to combust on-site generated biogas and on-site generated used oil. Coal coke, anthracite coal, or sub-bituminous coal are fed at the top of the vertical lime kiln with lime rock. The lime kiln produces quicklime (CaO), which is made into a calcium hydroxide (Ca(OH)2) slurry in the lime slaker and used for the purification of the sugar. During startup of the kiln, the entirety of the lime kiln combustion gases are vented to a cyclone for the control of particulate emissions. During steady-state operation of the sugar beet processing plant, a portion of the lime kiln combustion gases are vented through a series of carbonation process tanks to separate calcium from the refined sugar solution through a precipitation reaction. A portion of the lime kiln particulate and sulfur dioxide (SO2) emissions routed to the carbonation process tanks are inherently reduced by the carbonation process, which acts similarly to a gas scrubber.


Particulate emissions from each pulp dryer are controlled by multiclones, with about 25 percent of the exhaust gases from each multiclone vented in series to a fabric filter. Particulate emissions from the sugar dryer, sugar cooler, sugar transfer equipment, sugar storage silos, and pulp pellet transfer equipment are controlled with fabric filters. Particulate emissions from the pulp pellet mills and pulp pellet cooler are controlled by a cyclone. Biogas that is not routed from the anaerobic digester to one of the pulp dryers or boilers it is routed to a flare. All biogas generated in the covered equalization pond is routed to a different flare. The annual sugar beet processing operation (campaign) typically runs between late August and May of each year, 24 hours per day. The sugar beet processing plant typically starts up two to three days before starting to slice sugar beets, and shuts down two to four days after beet slicing has stopped. During each campaign, sugar inventory is built up in the storage silos. Sugar mixing, packaging, and distribution operations continue to operate after the campaign has ended. The primary pollutants emitted from the facility are particulate matter, particulate matter less than 10 microns, and particulate matter less than 2.5 microns (PM/PM10/PM2.5), sulfur dioxide (SO2), nitrogen oxides (NOX), carbon monoxide (CO), volatile organic compounds (VOC), and hydrogen chloride (HCl) and hydrogen fluoride (HF) acid gases from the combustion of sub-bituminous coal and coal coke, with lesser hazardous air pollutant (HAP) emissions from the combustion of fossil fuels.

1.6 Changes to permit

The permit does not authorize any specific modifications, however, the MPCA has a combined operating and construction permitting program under Minnesota Rules Chapter 7007, and under Minn. R. 7007.0800, the MPCA has authority to include additional requirements in a permit. Under that authority, the following changes to the permit are also made through this permit action:

The permit has been updated to reflect current MPCA templates and standard citation formatting.

Completed requirements and the requirements for equipment that has been removed have been deleted.

Some requirements have been reordered to help with clarity (i.e., similar requirements are grouped).

Monitoring conditions for the pulp dryer multiclone and fabric filter pressure drop limits in the permit were revised to contain a protocol for resetting the limit via an Approved Replicable Methodology, or ARM. This is a concept defined in the federal Part 70 permit rule as conditions that specify a replicable method for revising or updating monitoring parameters contained in the permit without the need to do a permit amendment.


Total Facility (TFAC 3)

The citation for the Minnesota ambient air quality standards (MAAQS) for hydrogen sulfide (H2S) have been updated to the following: [Minn. R. 7007.0800, subp. 2(A) & (B), Minn. R. 7009.0020-7009.0080, Minn. Stat. 116.07, subd. 4a(a)]. This is the standard permit citation for conditions related to protection of state ambient air quality standards.

The permit language “This is a state only requirement and is not enforceable by the EPA Administrator or citizens under the Clean Air Act” has been removed from the H2S MAAQS, because this standard has been incorporated into Minnesota’s state implementation plan (SIP).

A requirement to submit monthly H2S monitoring data reports has been added to the permit. COMG 5 (Material Handling Source Requirements (NOT Subject to CAM)) and COMG 6 (Material Handling Source Requirements (Subject to CAM))

Many of the material handling units at the facility were grouped in COMG 5 (GP006) or COMG 6 (GP007) in the last permit. These groups each contained the Post-1969 IPER standard, Title I emission limits derived from the 1999 PM/PM10 air dispersion modeling analysis (0.020 gr/dscf), and air pollution control equipment operational requirements. In this permit, the emission limits originally listed at COMGs 5 and 6 have been relocated to their applicable material handling unit (EQUI) subject items, and the air pollution control equipment operational requirements have been relocated to their applicable fabric filter subject items. This was done for the following reasons: 1) to more clearly identify which units are subject to Title I emission limits derived from the 1999 PM/PM10 air dispersion modeling analysis; 2) to more clearly identify which emission standards apply to each individual emissions unit; and 3) to specifically identify the existing emission unit/control equipment relationships in the permit. COMG 5 and COMG 6 have been removed from the permit.

The Bag Clipping Collection System (EQUI 72/EU033) was misidentified in a previous permit action as venting to a fabric filter and being subject to Compliance Assurance Monitoring (CAM). In actuality, this unit vents to a cyclone. This unit has been re-categorized as an insignificant activity under Minn. R. 7007.1300, subp. 3(F) because the uncontrolled emissions are estimated to be well below the threshold listed under this subpart.

Sugar Silos (EQUIs 7 - 14 and COMG 3)

The control equipment operating requirements for the sugar silos (EQUIs 7, 8, 9, 10, 11, 12, 13, and 14) have been relocated to subject items TREAs 18, 17, 16, 15, 14, 13, 12, and 11 in the permit, respectively.

The sugar silos were each in operation prior to July 9, 1969; therefore, these units are subject to Minn. R. 7011.0710 (Minnesota Standards of Performance for Pre-1969 Industrial Process Equipment). The applicable PM and opacity standards of Minn. R. 7011.0710 have been listed at subject items EQUIs 7 - 14 in the permit, and the PM and opacity standards of Minn. R. 7011.0715 have been removed from subject item COMG 1 of the permit.

The PM and PM10 emission rate limits (0.020 gr/dscf) derived from the 1999 PSD air dispersion modeling were relocated to subject items EQUIs 7 - 14 in the permit.

Recurring PM, PM10, and opacity performance testing requirements have been removed from the sugar silos because past testing results reaffirm that operation and daily monitoring of the control equipment is sufficient to ensure ongoing compliance with the emission limits.

The Permittee submitted an administrative amendment application on June 13, 2011 to revise a permit condition derived from the 1999 PSD air dispersion modeling for improved clarity. The COMG 3 operating restriction of no more than two sugar silos in operation at one time has been revised to specify that only two sugar silos may receive sugar at one time. Sugar reclaim operations are captured and vented to an independent fabric filter, and thus the intent of the silo operating limit was only meant to apply to silo filling operations (not silo reclaim operations). Further discussion may be found in Section 3.4 of this TSD.


Recordkeeping requirements for number of sugar silos receiving sugar has been removed from the permit. There are only two sugar elevators serving the sugar silos; one for silo filling, and the other for recirculating sugar in order to prevent the sugar from setting up and hardening. Under the current operational design of the system, only two silos may physically receive sugar at any given time.

Boiler #1 (EQUI 1), Boiler #2 (EQUI 2), and Boiler #3 (EQUI 16)

The control equipment operating requirements for the three electrostatic precipitators for Boilers #1, #2, and 3 have been relocated to subject items TREAs 26, 27, and 25 in the permit, respectively.

The boilers are subject to 40 CFR pt. 63, subp. DDDDD (NESHAP for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters). The applicable requirements from this standard have been added to the permit at subject items EQUIs 1, 2, and 16.

The clean startup fuel allowed by 40 CFR pt. 63, subp. DDDDD which is used by the facility (diesel fuel) has been added to the list of authorized fuel types in the permit at EQUIs 1, 2, and 16. Additionally, biogas combusted in the boilers is limited to biogas meeting the specifications of an “other gas 1 fuel” under 40 CFR § 63.7575, and used oil and used oil sorbents for use as fuel are required to meet the specifications of 40 CFR § 279.11 (on-spec used oil). The boilers must obtain more than 10% of annual heat input capacity from coal in order to qualify under the “unit designed to burn coal” subcategory of 40 CFR pt. 63, subp. DDDDD.

Recurring opacity performance testing requirements have been removed from the boilers, because each unit now uses COMS to measure the stack opacity.

Since the averaging basis used to demonstrate compliance with the PM and PM10 emission rate limits (15.0 lb/hr) derived from the 1999 PSD air dispersion modeling is the average of three performance test runs, the limits have been revised to specify a “3-hour average” basis.

Each boiler was previously subject to a sulfur dioxide emission limitation of 1.0 lb SO2/MMBtu heat input. This emission limit was initially proposed by the facility during the facility’s review of the original Part 70 air permit (August 1997). Based on the fuel sulfur content limit and fuel analysis methodology in the permit, it was determined prior to issuance of permit #02700001-006 (June 27, 2001) that the short-term (1- to 3-hour) emission rate of SO2 is 1.23 lb/MMBtu when combusting sub-bituminous coal. Since there is no underlying regulatory basis behind the 1.0 lb SO2/MMBtu heat input emission limits for each boiler, these limits have been removed from the permit and replaced with the applicable SO2 emission standard from Minn. R. 7011.0510 (Minnesota Standards of Performance for Existing Indirect Heating Equipment) (4.0 lb SO2/MMBtu heat input for solid fossil fuels, 2.0 lb SO2/MMBtu heat input for liquid fossil fuels). Additionally, recurring sulfur dioxide performance tests for EQUIs 1, 2, and 16 have been removed from the permit because the fuel sulfur content limits and associated monitoring requirements are sufficient to ensure compliance with this standard.

New electrostatic precipitator opacity excursion levels (Compliance Assurance Monitoring) have been added at subject items TREAs 25-27 in the permit. More information may be found in Section 3.10 of this TSD.

The EQUI 16 (Boiler #3) 8-hour block average steam flow limit has been removed from the permit. This operating limit only served to identify the maximum achievable operating rate of this boiler, and did not serve any function as a compliance measure. Additionally, this boiler is subject to new 30-day rolling average steam flow operating limits under 40 CFR pt. 63, subp. DDDDD, which are reset following compliance tests for each pollutant regulated under this standard.

Pulp Pellet Cooler (EQUI 3)

The control equipment operating requirements for the pulp pellet cooler cyclone have been relocated to subject item TREA 23 in the permit.

The pulp pellet cooler is subject to Minn. R. 7011.0715 (Minnesota Standards of Performance for post-1969 Industrial Process Equipment). The applicable particulate emission limit under this standard has been added to the permit at subject item EQUI 3.


It was determined that the PM and PM10 emission rate limits (2.0 lb/hr) derived from the 1999 PSD air dispersion modeling were intended to apply to the pulp pellet cooler as well as the pellet process equipment vented to STRU 1 (includes pellet mills nos. 1 - 3 (EQUIs 119 - 121)). For clarity, these limits have been moved to subject item STRU 1 in the permit. Since the averaging basis used to demonstrate compliance with these limits is the average of three performance test runs, the limits have been revised to specify a “3-hour average” basis.

South Pulp Dryer (EQUI 17) and North Pulp Dryer (EQUI 22)

The control equipment operating requirements for the south pulp dryer multiclone and fabric filter have been relocated to subject items TREAs 37 and 52 in the permit, respectively. The control equipment operating requirements for the north pulp dryer multiclone and fabric filter have been relocated to subject items TREAs 38 and 53 in the permit, respectively.

In previous permits, the fabric filters serving the pulp dryers were identified as “low temperature (T < 180 °F)” fabric filters. The fabric filters are designed to withstand temperatures greater than 250 °F, so the control equipment types have been updated accordingly (now “high-temperature fabric filters”).

The Permittee submitted a major permit amendment application to revise the EQUI 17 and EQUI 22 PM and PM10 emission rate limits derived from the 1999 PSD air dispersion modeling analysis. The new EQUI 17 PM and PM10 emission rate limits are each 25.0 lb/hr, and the new EQUI 22 PM and PM10 emission rate limits are each 15.0 lb/hr. This is discussed further in Section 3.2.2 of this TSD. Since the averaging basis used to demonstrate compliance with these limits is the average of three performance test runs, the limits have been revised to specify a “3-hour average” basis.

Based on the new PM and PM10 emission rates for the south pulp dryer, this unit has allowable controlled potential emissions of greater than 100 tons per year. This unit has been reclassified as a “Large PSEU” under Compliance Assurance Monitoring; thus, the south pulp dryer multiclone (TREA 37) and fabric filter (TREA 52) are subject to a monitoring frequency of at least once every 15 minutes.

Initial opacity test (EPA method 9) requirements have been added to the permit at subject items EQUI 17 and EQUI 22.

Daily recordkeeping requirements for each 8-hour block average dry pulp process rate have been added to the permit at subject items EQUI 17 and EQUI 22.

Vertical Lime Kiln (EQUI 20)

The control equipment operating requirements for the vertical lime kiln dual cyclone have been relocated to subject item TREA 28 in the permit.

An additional significant figure has been added to the coke sulfur content limit (now 0.90% by wt.).

The fuel sulfur content determination procedure for the vertical lime kiln has been revised to include both coal and coke.

In the requirement listing the allowed fuel types, “pulverized coal” has been updated to specify “pulverized sub-bituminous coal” as the intended allowed fuel type.

In addition to the lime rock throughput and damper position operating limits, an additional operating limit for the combined coke and coal usage rate has been added to the permit. This limit has been set as 110% of the 3-hour average combined coke and coal usage rate from the most recent compliant performance test.

The damper position operating limit has been revised to 70% open based on the operating conditions of recent performance tests demonstrating compliance, which were conducted on 10/12/2016 and 10/10/2019.

Daily recordkeeping requirements for each 8-hour block average lime rock throughput, each 8-hour combined coke and coal throughput, and each daily maximum observed damper position have been added to the permit at subject item EQUI 20.

It was determined that the PM, PM10, and SO2 emission rate limits derived from the 1999 PSD air dispersion modeling that were listed at EU004 in the previous permit were intended to apply to the portion of the lime kiln emissions vented to STRU 33 (Vertical Lime Kiln). For clarity, these limits have


been moved to subject item STRU 33 in the permit. Since the averaging basis used to demonstrate compliance with the PM and PM10 limits is the average of three performance test runs, these limits have been revised to specify a “3-hour average” basis.

In addition to STRU 33 and STRU 34, STRU 57 (Carbonation Pressure Control Vent) is a pressure control vent which may emit lime kiln flue gas. The permit has been revised to more clearly identify each authorized operating condition, and which stacks are authorized for use during each operating condition. A past permit allowed the use of anthracite coal, pulverized sub-bituminous coal, and natural gas as alternative fuel types for the lime kiln.

The original STRU 33 sulfur dioxide and PM/PM10 emission limits were relied upon in order to demonstrate that this fuel type change authorization did not exceed the major modification thresholds; therefore, the citation “Title I Condition: Avoid major modification under 40 CFR 52.21(b)(2)” has been added to these limits. The permit has been revised to require performance testing within 45 days of initial use of anthracite or sub-bituminous coal, to verify compliance with these limits.

A vertical lime kiln operating scenario (Operating Scenario 3) has been added to the permit which preauthorizes up to 72 hours per year of lime kiln operation while the dual cyclones (TREA 28) are not operating. During this operating scenario, all vertical lime kiln flue gases are required to be vented to the gas washer and carbonation process.

Emergency Electrical Generator Set (EQUI 21)

This engine is subject to 40 CFR pt. 63, subp. ZZZZ (NESHAP for Stationary Reciprocating Internal Combustion Engines). The applicable requirements from this standard have been added to the permit at subject item EQUI 21.

This engine is subject to Minn. R. 7011.2300 (Minnesota Standards of Performance for Stationary Internal Combustion Engines). The applicable sulfur dioxide standard at Minn. R. 7011.2300, subp. 2(B) has been added to the permit at subject item EQUI 21.

The allowed fuel type for this engine has been updated from “distillate fuel oil” to “diesel fuel” at the request of the Permittee to more specifically identify the fuel type used.

A fuel sulfur content limit of 0.0015% S by weight has been added to the permit for this engine, as the compliance demonstration method for the SO2 emission standard at Minn. R. 7011.2300, subp. 2(B).

Sugar Dryer (EQUI 18) and Wet Sugar Elevator (EQUI 127)

The control equipment operating requirements for the sugar dryer fabric filter have been relocated to subject item TREA 35 in the permit.

The sugar dryer and wet sugar elevator are subject to Minn. R. 7011.0715 (Minnesota Standards of Performance for post-1969 Industrial Process Equipment). The applicable particulate emission limit under this standard has been added to the permit at subject items EQUIs 18 and 127.

It was determined that the PM and PM10 emission rate limits (1.0 lb/hr) derived from the 1999 PSD air dispersion modeling were intended to apply to the sugar dryer as well as the material handling equipment vented to STRU 2 (includes the wet sugar elevator (EQUI 127)). For clarity, these limits have been moved to subject item STRU 2 in the permit. Since the averaging basis used to demonstrate compliance with these limits is the average of three performance test runs, the limits have been revised to specify a “3-hour average” basis.

The sugar dryer and wet sugar elevator went through prevention of significant deterioration (PSD) review prior to their installation in 1983. These units are subject to best available control technology (BACT) limits, as noted in the 1988 sugar dryer and cooler operating permit (29A-99-O-7). These limits may have been inadvertently removed during a past permit action, but have now been added back into the permit at subject items EQUIs 18 and 127 and STRU 2.


Sugar Cooler (EQUI 19), Granulator Discharge Scroll (EQUI 128), Granulator Product Elevator (EQUI 129), and Granulator Discharge Remelt Scroll (EQUI 130)

The control equipment operating requirements for the sugar cooler fabric filter have been relocated to subject item TREA 36 in the permit.

The sugar cooler, granulator discharge scroll, granulator product elevator, and granulator discharge remelt scroll are subject to Minn. R. 7011.0715 (Minnesota Standards of Performance for post-1969 Industrial Process Equipment). The applicable particulate emission limit under this standard has been added to the permit at subject items EQUIs 19 and 128-130.

It was determined that the PM and PM10 emission rate limits (1.0 lb/hr) derived from the 1999 PSD air dispersion modeling were intended to apply to the sugar cooler as well as the material handling equipment vented to STRU 3 (includes the granulator discharge scroll (EQUI 128), granulator product elevator (EQUI 129), and granulator discharge remelt scroll (EQUI 130)). For clarity, these limits have been moved to subject item STRU 3 in the permit. Since the averaging basis used to demonstrate compliance with these limits is the average of three performance test runs, the limits have been revised to specify a “3-hour average” basis.

The sugar cooler, granulator discharge scroll, granulator product elevator, and granulator discharge remelt scroll went through prevention of significant deterioration (PSD) review prior to their installation in 1983. These units are subject to best available control technology (BACT) limits, as noted in the 1988 sugar dryer and cooler operating permit (29A-99-O-7). These limits may have been inadvertently removed during a past permit action, but have now been added back into the permit at subject items EQUIs 19 and 128-130 and STRU 3.

New Equipment Installed Since the Last Operating Permit Reissuance:

Various Sugar Handling and Packaging Equipment - The following emission units have been installed since the last operating permit reissuance: Bag Clipping No. 1 (EQUI 66), Weibull Scroll (EQUI 93), 3rd Floor Production Scroll to Bins (EQUI 98), Middle (South) Silo Receiving Elevator (EQUI 101), South Gantry Scroll (EQU 102), Remelt Tote Hood No. 1 (EQUI 132), Remelt Tote Hood No. 2 (EQUI 133), Remelt Tote Hood No. 3 (EQUI 134), Remelt Tote Hood No. 4 (EQUI 135), 1 North Scroll (EQUI 192), 1 South Scroll (EQUI 193), 2 North Scroll (EQUI 194), 2 South Scroll (EQUI 195), 3 North Scroll (EQUI 196), 3 South Scroll (EQUI 197), 4 North Scroll (EQUI 198), 4 South Scroll (EQUI 199), 5 North Scroll (EQUI 200), 5 South Scroll (EQUI 201), 6 North Scroll (EQUI 202), 6 South Scroll (EQUI 203), 7 North Scroll (EQUI 204), 7 South Scroll (EQUI 205), 8 North Scroll (EQUI 206), 8 South Scroll (EQUI 207), Bulk Loading Vacuum (EQUI 209), Bulk Loading Scroll (EQUI 210), Incline Scroll (EQUI 211), G Scroll (EQUI 212), Reclaim Elevator (EQUI 213), Railcar Scroll (EQUI 214), Railcar Loadout No. 1 (EQUI 215), Railcar Loadout No. 2 (EQUI 216), Railcar Loadout No. 3 (EQUI 217), and Railcar Loadout No. 4 (EQUI 218). There were no permit amendment applications or notifications submitted for these units. Since the Minnesota Rules for conditionally insignificant activities at Minn. R. 7008.4110 have been revised, units that previously were considered insignificant activities under this subpart have now been added to the permit as emission units. Each of these units are subject to the Minnesota Performance Standards for post-1969 Industrial Process Equipment.

Pulp Press No. 0 and Pressed Pulp Scroll (EQUIs 157 and 158): Pulp Press No. 0 and the Pressed Pulp Scroll were installed in 2012. No permit amendment application or notification was submitted for these units. The facility has demonstrated that project emissions increases associated with the additional steam requirement (for evaporation of the additional juice) remains below the significant emission rates (SER). Other process rates are not anticipated to increase on account of the evaporation system throughput capacity (the current process bottleneck).

Sulfur Stove (EQUI 159): The sulfur stove is a new emission unit was installed in 2010. No permit amendment application or notification was submitted for this unit. This unit burns elemental sulfur for production of sulfur dioxide, which is used in the sugar purification process. Prior to installation of the sulfur stove, liquid sulfur dioxide was used for this purpose. The sulfur stove is subject to Minn. R. 7011.0715 (Minnesota Standards of Performance for post-1969 Industrial Process Equipment). The


applicable particulate emission limit and opacity limit under this standard has been added to the permit at subject item EQUI 159. One-time performance testing requirements have been added to the permit to quantify sulfur dioxide emission factors from the pulp press SO2 vents (STRUs 62, 63, 101, and 102) and sulfur stove absorber stacks (STRUs 64 and 100).

Truck Traffic on Paved Roads (FUGI 1):

The requirement to complete at least seven fugitive dust control operations for the paved truck haul roads has been revised to include an exemption during low-traffic periods (based on a low truck traffic threshold of 240 trucks as proposed by the Permittee). In the PM10 air dispersion modeling completed in 1999, truck traffic levels up to 395 trucks per day were modeled with no apparent control effectiveness from fugitive dust control operations.

2. Regulatory and/or statutory basis 2.1 New source review (NSR)

The facility is an existing major source under New Source Review regulations. This permit action includes modifications to existing PM/PM10 air dispersion modeling-based permit limits under the Prevention of Significant Deterioration (PSD) program on the South and North Pulp Dryers (EQUIs 17 and 22, respectively).

2.2 Part 70 permit program The facility is a major source under the Part 70 permit program. No changes are authorized by this permit.

2.3 New source performance standards (NSPS) The Permittee has stated that no New Source Performance Standards apply to the operations at this facility. The facility is not subject to 40 CFR pt. 60, subp. Db (Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units), because each of the three boilers (EQUI 1, EQUI 2, and EQUI 16) were constructed prior to June 19, 1984. The facility is not subject to 40 CFR pt. 60, subp. K (Standards of Performance for Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After June 11, 1973, and Prior to May 19, 1978), because the facility does not have any petroleum liquid storage vessels that were constructed between these two dates. The facility is not subject to 40 CFR pt. 60, subp. Kb (Standards of Performance for Post-July 23, 1984 Volatile Organic Liquid Storage Vessels), because none of the storage vessels at the facility that were constructed after July 23, 1984 have a capacity greater than or equal to 75 m3. These include tank #23 (diesel fuel, 3.8 m3 capacity, constructed in 1990), tank #24 (gasoline fuel, 3.8 m3 capacity, constructed in 1990), tank #32 (diesel fuel, 22.7 m3 capacity, constructed in 1993), tank #33 (diesel fuel, 22.7 m3 capacity, constructed in 1993), tank #46 (propylene glycol, 62.1 m3 capacity, constructed in 2008), and tank #47 (propylene glycol, 62.1 m3 capacity, constructed in 2008). The facility is not subject to 40 CFR pt. 60, subp. Y (Standards of Performance for Coal Preparation and Processing Plants), because the coal processing and conveying equipment and open storage piles were constructed prior to October 27, 1974. The facility processes more than 200 tons of coal per day; therefore, any new affected facilities (including coal processing and conveying equipment, transfer and loading systems, and open storage piles) will be subject to this standard. The facility is not subject to 40 CFR pt. 60, subp. DD (Standards of Performance for Grain Elevators). This standard applies to any grain terminal elevator or any grain storage elevator constructed after August 3, 1978. As defined at 40 CFR § 60.301, grain means “corn, wheat, sorghum, rice, rye, oats, barley, and


soybeans.” The facility only receives and processes sugar beets; therefore, 40 CFR pt. 60, subp. DD does not apply. The facility is not subject to 40 CFR pt. 60, subp. HH (Standards of Performance for Lime Manufacturing Plants), because 1) the lime kiln at the facility (EQUI 20) was constructed prior to May 3, 1977; and 2) because the lime kiln at the facility is a vertical lime kiln (40 CFR pt. 60, subp. HH only applies to rotary lime kilns). The facility is not subject to 40 CFR pt. 60, subp. OOO (Standards of Performance for Nonmetallic Mineral Processing Plants), because the facility does not operate a lime rock crusher. The facility is not subject to 40 CFR pt. 60, subp. IIII (Standards of Performance for Stationary Compression Ignition Internal Combustion Engines), because the emergency generator (EQUI 21) was constructed prior to July 11, 2005.

2.4 National emission standards for hazardous air pollutants (NESHAP) The facility is an existing major source of hazardous air pollutants (HAPs). 40 CFR pt. 63, subp. ZZZZ (National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) applies to any existing, new, or reconstructed reciprocating internal combustion engines (RICE) located at a major or area source of HAP emissions, excluding stationary RICE being tested at a stationary RICE test cell/stand. The emergency generator (EQUI 21) is an existing emergency engine subject to 40 CFR pt. 63, subp. ZZZZ. 40 CFR pt. 63, subp. DDDDD (National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters) applies to any existing, new, or reconstructed industrial, commercial, and institutional boilers and process heaters located at a major source of HAP emissions. Boiler #1 (EQUI 1), Boiler #2 (EQUI 2), and Boiler #3 (EQUI 16) are existing industrial boilers subject to 40 CFR pt. 63, subp. DDDDD. These boilers are part of the “stokers designed to burn coal/solid fossil fuel” subcategory. The facility is not subject to 40 CFR pt. 63, subp. AAAAA (National Emission Standards for Hazardous Air Pollutants for Lime Manufacturing Plants), because this standard does not apply to lime manufacturing plants located at a beet sugar manufacturing plant.

2.5 Acid rain program None of the three coal-fired boilers serves a generator that produces electricity for sale; therefore, these units are not subject to the requirements of the Acid Rain Program.

2.6 Minnesota mercury reduction plan American Crystal Sugar - Moorhead has actual mercury emissions of greater than three pounds per year, making this facility a “mercury emission source” as defined in Minn. R. 7005.0100, subp. 23b. Pursuant to Minn. R. 7007.0502, subp. 3, owners or operators of an existing mercury emissions source are required to prepare a mercury reduction plan, except that Minn. R. 7007.0502, subp. 6(C)(1)(a) specifies that a reduction plan is not required if actual mercury emissions from an industrial coal-fired boiler are less than five pounds per year. On October 16, 2015, American Crystal Sugar - Moorhead submitted mercury emissions calculations demonstrating that the actual emissions for each of the three coal-fired boilers at the facility were less than five pounds per year. In a letter from MPCA to American Crystal Sugar - Moorhead dated November 5, 2015, MPCA determined that the facility was not required to submit a mercury reduction plan. As a mercury emission source, American Crystal Sugar - Moorhead is required to submit an annual mercury emissions inventory report pursuant to Minn. R. 7019.3000, subp. 3.

3. Technical information

3.1 Calculations of potential to emit (PTE) Attachment 1 to this TSD contains a summary of the PTE of the Facility and detailed spreadsheets and supporting information prepared by the MPCA and the Permittee. Attachment 2 to this TSD contains the projected actual emissions increase calculations for the installation of Pulp Press No. 0 (EQUI 157). This demonstrates that this insignificant modification was not a major modification for PSD. Boilers The potential to emit (PTE) for the boilers is calculated using emission factors from AP-42 Section 1.1 (Bituminous and Subbituminous Coal Combustion) for combustion of sub-bituminous coal, Section 1.11 (Waste Oil Combustion) for combustion of used oil, emission factors provided by the San Diego County Air Pollution Control District for the combustion of biogas (https://www.sandiegocounty.gov/content/dam/sdc/apcd/PDF/Misc/EFT/Gas_Combustion/APCD_Boiler_Digester_Gas_Fired_Uncontrolled.pdf), and site-specific emission limits. The biogas criteria pollutant emission factors from this source are derived from AP-42 Section 1.4 (Natural Gas Combustion) emission factors that have been adjusted based on rated heat value of the biogas (Btu/cf). Maximum hourly combustion of waste oil is approximated to be 25 gallons per hour and maximum hourly combustion of biogas is approximated to be 120,000 cubic feet (2,000 cfm) based on boiler limitations. The potential to emit sulfuric acid mist was estimated using methods presented in Electric Power Research Institute (EPRI)’s “Estimating Total Sulfuric Acid Emissions from Stationary Power Plants.” Greenhouse gas PTE was estimated using emission factors from 40 CFR pt. 98. Although each boiler is authorized to individually combust up to the COMG 4 group limit of 1,250 gallons of oil per month on a 12-month rolling average (15,000 gallons of waste oil per year), the Permittee has chosen to calculate the potential to emit from waste oil combustion in the boilers assuming that each boiler combusts an equal 5,000 gallons of waste oil per year. While this is not a worst-case assumption for PTE purposes, it is inconsequential from an air dispersion modeling or regulatory standpoint. Sub-bituminous coal combustion is anticipated to have higher hourly emission rates of all criteria pollutants than waste oil combustion. When performing an air emissions risk assessment for certain hazardous air pollutants, the assumption of 5,000 gallons of waste oil per year per boiler may need to be reevaluated. Pulp Dryers The potential to emit (PTE) for the pulp dryers is calculated using emission factors from AP-42 Section 1.4 (Natural Gas Combustion) for combustion of natural gas, emission factors provided by the San Diego County Air Pollution Control District for the combustion of biogas (https://www.sandiegocounty.gov/content/dam/sdc/apcd/PDF/Misc/EFT/Gas_Combustion/APCD_Boiler_Digester_Gas_Fired_Uncontrolled.pdf), and site-specific emission limits and stack testing data. The Permittee has asserted that approximately 60% of the SO2 that is emitted from combustion of biogas is absorbed into the beet pulp. The SO2 emission rate accounting for this scrubbing effect (17.9 lb/hr) is required to be verified through performance testing. Sugar Cooling, Drying, and Handling Equipment Emission factor data is not readily available for sugar processing equipment. Controlled PTE for this equipment is calculated using an assumed fabric filter discharge concentration (gr/acf) and maximum rated airflow as well as site-specific emission limits. The uncontrolled PTE for this equipment is back-calculated using the permitted control efficiency (99% for PM and 93% for PM10/PM2.5). Particle size distribution data was not readily available for sugar handling operations, so an average particle size distribution was used


from similar sources to estimate the controlled PM2.5 emission rates. In the subject item details report, some of the PTE data for pound per hour (lb/hr), unrestricted tons per year (ton/yr) and limited tons per year (ton/yr) has been listed at the STRU subject item. Beet Pulp Pellet Handling Equipment Emission factor data is not readily available for beet pulp pellet handling equipment. Controlled PTE for this equipment is calculated using an assumed fabric filter discharge concentration (gr/scf) and maximum rated airflow as well as site-specific emission limits. The uncontrolled PTE for this equipment is back-calculated using the permitted control efficiency (99% for PM and 93% for PM10/PM2.5 for fabric filters, 80% for PM and 60% for PM10/PM2.5 for cyclones). Particle size distribution data was not readily available for sugar handling operations, so an average particle size distribution was used from similar sources to estimate the controlled PM2.5 emission rates. PTE for pulp pellet storage bins and pulp pellet loadout operations have been calculated using emission factors from AP-42 Section 9.9.1 (Grain Elevators and Processes). In the subject item details report, some of the PTE data for pound per hour (lb/hr), unrestricted tons per year (ton/yr) and limited tons per year (ton/yr) has been listed at the STRU subject item. Lime Kiln Emission factor data is available for various rotary (horizontal) lime kilns, but less data is available for shaft (vertical) lime kilns. PTE is estimated using emission factors from AP-42 Sections 1.1 (Bituminous and Subbituminous Coal Combustion), 1.2 (Anthracite Coal Combustion), 1.4 (Natural Gas Combustion), and 40 CFR pt. 98. NOX emissions were estimated using lime kiln emissions data from Europe, as provided by HDR engineering. Sulfur dioxide emissions are reduced by the carbonation process, which acts similarly to a wet scrubber. Additionally, the Permittee has asserted that the raw lime rock in the lime kiln absorbs some of the SO2. The modeled SO2 emission rates for the lime kiln vent (STRU 33) and the carbonation security tank vent (STRU 34) take these scrubbing effects into account. The modeled emission rates for these two stacks are required to be verified through performance testing. Sulfur Stove, Pulp Presses, Press Water Screens, and Wet and Pressed Pulp Conveyors The sulfur stove combusts sulfur to produce sulfur dioxide, where it is then absorbed in a column and used in the process as a biocide. There are a number of different locations in the process where the produced sulfur dioxide may be emitted, including the Pulp Press SO2 Vents (1 through 4). As a rough estimate, emissions have been calculated assuming that 0.2% of the sulfur dioxide produced from the sulfur stove is emitted from the east and west sulfur stove absorber stacks, and the remainder (99.8%) of the SO2 produced is emitted proportionally from each of the 4 Pulp Press SO2 Vents based on airflow. The SO2 emissions from each of these stacks will be measured during the next permit term in determine appropriate emission factors for these sources.

3.2 Dispersion modeling 3.2.1. Prevention of Significant Deterioration (PSD) Air Dispersion Modeling (1999) Under the prevention of significant deterioration (PSD) program, the facility triggered the requirement to complete air dispersion modeling to show modeled compliance with the PM10, SO2, NO2, and CO National Ambient Air Quality Standards (NAAQS). Several operating restrictions were assumed when the modeling was conducted, so these have been incorporated as permit limits (e.g., hourly stack SO2 emission rates, etc.) in the Part 70 Reissuance permit. In addition, per MPCA practice, a table of the modeled parameters has been added to the permit as an appendix (Appendix B). Other than the specific operating restrictions


mentioned above, the parameters listed in Appendix B of the permit describe the operation of the facility at maximum capacity. In other words, the flow rates and temperatures listed in Appendix B represent the minimum parameters at the maximum emission rates. The MPCA does not require any specific compliance demonstration with these parameters because they are worst-case conditions. The purpose of listing the parameters in the permit appendix is to provide a benchmark for determining if and when additional modeling is required. Particulate Matter < 10 Micron (PM10) Air dispersion modeling was performed for particulate matter < 10 micron in diameter (PM10) emissions in March 1999. The modeling predicted impacts of less than 95% of the 24-hour average PM10 NAAQS, which remains the current PM10 standard. The permit has been revised to include requirements that an Equivalent or Better Dispersion (EBD) modeling analysis for PM10 be performed for any changes that affect the modeled parameters or emission rates for PM10, or for additions to the information documented in Appendix B of the permit. The permit has also been revised to include requirements that a refined remodeling analysis for PM10 be performed if (1) the results of the EBD modeling analysis do not demonstrate equivalent or better dispersion characteristics; (2) a conclusion cannot readily be made about the dispersion, or (3) the criteria in the EBD Modeling Triggers requirement are met and the Permittee has previously conducted three successive EBD analyses using the same Baseline Modeling. Sulfur Dioxide (SO2) Air dispersion modeling was performed for sulfur dioxide (SO2) emissions in March 1999 and in September 1999. The modeling predicted impacts of less than 60% of the National Ambient Air Quality Standards of the time. Nitrogen Dioxide (NO2) Air dispersion modeling was performed for nitrogen dioxide (NO2) emissions in March 1999. The modeling predicted impacts of less than 50% of the National Ambient Air Quality Standards of the time. Table 8.

The revised 3-hour (and 1-hour) average SO2 modeling results were submitted on September 15, 1999.

3.2.2. Equivalent or Better Dispersion (EBD) Modeling (2018) and Modification of Pulp Dryer Modeling-Based Emission Limits On May 4, 2018 MPCA received a major amendment application requesting modification of the PM and PM10 air dispersion modeling-based emission limits for the north and south pulp dryers (EQUIs 17 and 22). In this application, the Permittee requested that the south pulp dryer PM and PM10 emission limits be increased from 20.0 lb/hr to 25.0 lb/hr, and that the north pulp dryer PM and PM10 emission limits be decreased from 20.0 lb/hr to 15.0 lb/hr. Based on the permit requirements of permit # 02700001-011, the major permit amendment application required an equivalent or better dispersion (EBD) analysis to be included with the permit amendment application. The required EBD analysis was completed on March 5, 2018 and approved by MPCA on March 9, 2018. The projected PM10 impact resulting from the change is summarized in Table 10 below. Table 10. Equivalent or Better Dispersion (EBD) Modeling Results (March 5, 2018)

Does the change have equivalent or better dispersion characteristics?

3/5/2018 PM10 24-hour 2.59 5.0 Yes – the impact is less than the PM10 Significant Impact Level (SIL)

An image showing the modeled impacts from the EBD modeling are included as Attachment 7 to this TSD. As shown in Table 10 and Attachment 7, the 24-hour average PM10 EBD modeling result of 2.59 µg/m3 is less than the 24-hour average PM10 SIL (5.0 µg/m3); therefore, the Permittee has demonstrated that this proposed change has equivalent dispersion characteristics. The permit has been amended to reflect the north and south pulp dryer PM and PM10 emission limits proposed by the Permittee in the major permit amendment application. 3.2.3. National Ambient Air Quality Standards (NAAQS) Modeling Demonstration Sulfur Dioxide (SO2) In 2010, a new 1-hour average SO2 NAAQS became effective. The 1-hour average SO2 concentration that was modeled in September 1999 (948.3 µg/m3) is approximately 480% of the current 1-hour average SO2 NAAQS, without taking the specific rule allowances into consideration (the 2010 1-hour SO2 NAAQS is the 99th percentile of 1-hour daily maximum concentrations, averaged over 3 years). This is shown in Table 11 below. The Permittee is required by the permit to complete air dispersion modeling to demonstrate compliance with the 1-hour average SO2 NAAQS. The permit-required modeling serves as a NAAQS compliance demonstration, and is not required under Prevention of Significant Deterioration (PSD) rules. Nitrogen Dioxide (NO2) In 2010, a new 1-hour average NO2 NAAQS became effective. The Permittee is required by the permit to complete air dispersion modeling to demonstrate compliance with the 1-hour average NO2 NAAQS standard, because: 1) no 1-hour average NO2 dispersion modeling has been performed for this facility; 2) the facility has high emission rates of nitrogen oxides (actual emissions of NOX exceed 500 tons per year); and 3) an appropriate time to update the nitrogen oxides air dispersion modeling is concurrent with the required


updates to the sulfur dioxide air dispersion modeling. The permit-required modeling serves as a NAAQS compliance demonstration, and is not required under Prevention of Significant Deterioration (PSD) rules. Carbon Monoxide (CO) Air dispersion modeling was performed for carbon monoxide emissions in 1989. A record of this air dispersion modeling report could not be located; however, the results of this modeling and the input parameters have been documented in recent permits for this facility. The carbon monoxide NAAQS has not been revised since this modeling analysis was conducted. Since the predicted 1-hour and 8-hour impacts were less than 28% of the respective standards, and the facility has not made significant changes to the carbon monoxide-emitting equipment, there are no further modeling-related requirements for carbon monoxide. The outdated air dispersion modeling parameters have been removed from Appendix B of the permit, since this outdated air dispersion modeling data no longer serves as an appropriate benchmark for comparing future air dispersion modeling data against.

Due to the record being incomplete and due to recent updates in modeling parameters and software, any future carbon monoxide air dispersion-related permitting decisions will be based on a new revised modeling demonstration.

3.3 Hydrogen Sulfide (H2S) Monitoring

The Permittee was required to submit a plan for installation and operation of a hydrogen sulfide (H2S) ambient monitoring network in permit #02700001-004 (issued May 13, 1999). Following the installation of this monitoring network, H2S data has been collected and recorded between April and October of each year. The Permittee is required to submit the H2S data collected each year to MPCA annually by November 30. All raw data must be included in this submittal, as noted in the June 21, 2018 letter from MPCA to Doug Emerson of American Crystal Sugar Company (Attachment 8 to this TSD). A summary report of the H2S monitoring data from 2017 has been included as Attachment 9 to this TSD. More-recent H2S data submitted by American Crystal Sugar – Moorhead is still under review by the MPCA.

3.4 Modification of COMG 1 (GP003) Sugar Silo Operating Condition Language In permit #02700001-011, GP003 contained a permit operating condition restricting the facility’s operation to only two sugar silos operating at one time. This operating condition was derived from PSD modeling conducted in 1999. In the administrative amendment application received on June 13, 2011, American Crystal Sugar requested to change the permit operating condition to specify that only two sugar silos may receive sugar at one time. American Crystal Sugar concluded that the intent of the original permit condition (“only two silos may be operated at one time”) was to allow particulate emissions to be generated from no more than two of the existing eight sugar storage silos at one time. In this analysis, American Crystal Sugar asserted that


particulate emissions are only generated from the sugar storage silos during filling operations (not during sugar storage silo reclaim operations). In order to provide clarification that the operating condition only applies to sugar storage silo filling operations, this permit condition has been amended as proposed by the Permittee.

3.5 Changes to Allowed Fuel Types for Boiler #1 (EQUI 1), Boiler #2 (EQUI 2), and Boiler #3 (EQUI 16) The allowed fuel types for Boilers #1, #2, and #3 have been updated to include clean startup fuels (as required by 40 CFR pt. 63, subp. DDDDD). The clean startup fuel used by American Crystal Sugar - Moorhead is diesel fuel. The applicable sulfur dioxide emission standard under Minn. R. 7011.0510, subp. 1 during liquid fuel combustion applies to diesel fuel combustion; therefore, a fuel sulfur content limit of less than or equal to 0.50 percent sulfur by weight has been added to the permit for this fuel type to ensure compliance with this standard. Biogas combusted in the boilers is required to meet the specifications of an “other gas 1 fuel” (mercury content of ≤ 40 µg/m3). Based on the materials sent to the on-site wastewater treatment, there is no evidence to suggest that the biogas would ever exceed this mercury content limit. Used oil is only authorized for continued use as a fuel if it 1) is generated onsite; and 2) meets the specifications outlined in 40 CFR § 279.11 (“on-spec” used oil). Combustion of on-spec used oil for energy recovery is not subject to regulation under 40 CFR pt. 279. Based on the information presented in the AP-42 Section 1.11 background document, used oil is estimated to contain 2700 to 7500 µg sulfur/g oil (0.27 to 0.75 weight % sulfur). Using an assumed 125 MMBtu/103 gallon heating value and emission factors from AP-42 Section 1.11, Table 1.11-2, it is estimated that the sulfur dioxide emission rate from used oil combustion will not exceed 0.882 lb/MMBtu. Additional requirements of 40 CFR pt. 63, subp. DDDDD apply if the Permittee elects to use fuels other than sub-bituminous coal outside of startup and shutdown periods, including (but not limited to): fuel analysis, emission rate calculations, performance testing, and reporting requirements.

3.6 Monitoring In accordance with the Clean Air Act, it is the responsibility of the owner or operator of a facility to have sufficient knowledge of the facility to certify that the facility is in compliance with all applicable requirements. For CAM, the Permittee submitted a CAM proposal as required by 40 CFR § 64.3. It can be found in Attachment 10 to this TSD. Further discussion of decisions about CAM can be found in Table 6. In evaluating the monitoring included in the permit, the MPCA considered the following:

the likelihood of the facility violating the applicable requirements;

whether add-on controls are necessary to meet the emission limits;

the variability of emissions over time;

the type of monitoring, process, maintenance, or control equipment data already available for the emission unit;

the technical and economic feasibility of possible periodic monitoring methods; and

the kind of monitoring found on similar units elsewhere. Table 12 summarizes the monitoring requirements.

The facility operates two H2S ambient air monitors, which are each located in strategic unobstructed areas on the premises near or on the property boundary. The facility is required to operate these monitors between April 1 and October 31 of each year. The monitors provide a direct measurement of ambient H2S air concentrations at these two locations, which provides a reasonable demonstration of compliance with the standard at all locations along the property boundary based on typical wind direction.

Daily records of used oil combustion and monthly calculation of the 12-month rolling average used oil combustion is adequate to ensure compliance with the limit.




EQUI 1

Boiler #1, North

PM10 ≤ 15.0 lb/hr


Recurring performance testing (EPA Methods 201A and 202)

Performance testing at worst-case conditions is the most direct method for determining compliance with an emission standard when a CEMS is not available.

Testing frequencies are typically set at 12, 36, or 60-month increments. Past test results, applicable rules, potential emissions, location of source, and past compliance history play a factor in setting the testing frequency. This permit requires testing to measure the PM10 emission rate (lb/hr) from EQUI 1 every 60 months. This frequency was chosen because past test results have not exceeded 54% of the limit. 60 months is the default testing frequency unless more frequent testing is warranted.

In addition to recurring performance testing, other limits at TREA 26 (and associated monitoring) ensure that this applicable requirement is being met.

PM ≤ 15.0 lb/hr


Recurring performance testing (EPA Methods 5 and 202)


Testing frequencies are typically set at 12, 36, or 60-month increments. Past test results, applicable rules, potential emissions, location of source, and past compliance history play a factor in setting the testing frequency. This permit requires testing to measure the PM emission rate (lb/hr) from EQUI 1 every 60 months. This frequency was chosen because past test results have not exceeded 42% of the limit. 60 months is the default testing frequency unless more frequent testing is warranted.


Filterable PM ≤ 0.040 lb/MMBtu

(40 CFR pt. 63, subp. DDDDD (Table 2)(item 2))

Recurring performance testing (EPA Method 5), steam flow and opacity operating limits, tune-ups

Monitoring required by 40 CFR pt. 63, subp. DDDDD is adequate to ensure compliance with the limit because this standard was promulgated after November 15, 1990. New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) promulgated after November 15, 1990 contain adequate monitoring requirements.





(Minn. R. 7011.0510, subp. 1)

None As specified at Minn. R. 7011.0530-7011.0535, compliance with this emission limit is measured using US EPA Method 5 for filterable PM only. Compliance with this limit can be demonstrated through the compliance method with the more-stringent filterable PM limit required under 40 CFR pt. 63, subp. DDDDD (0.040 lb/MMBtu). Filterable PM performance tests under 40 CFR pt. 63, subp. DDDDD are required at least once every 3 years.


Opacity ≤ 20%, with exceptions (Minn. R. 7011.0510, subp. 2)

COMS, calculations, recordkeeping

A COMS directly measures opacity. The COMS (required by 40 CFR pt. 63, subp. DDDDD) is used to monitor opacity of the emissions from the boiler.

SO2 ≤ 4.0 lb/MMBtu (solid fuels)

SO2 ≤ 2.0 lb/MMBtu (liquid fuels)

(Minn. R. 7011.0510, subp. 1)

None Other limits on fuel type and sulfur content ensure that this applicable requirement is being met.

Solid fuels combusted in the boiler are limited to sub-bituminous coal with a sulfur content of ≤ 0.50 percent by weight. When burning coal meeting this fuel sulfur content limit, the potential to emit SO2 is 1.23 lb/MMBtu.

Liquid fuels combusted in the boiler are limited to No. 1 or No. 2 distillate fuel oil/diesel fuel (≤ 0.5% sulfur by wt.) and used oil. The potential to emit SO2 when combusting liquid fuels is 0.53 lb/MMBtu.

Testing frequencies are typically set at 12, 36, or 60-month increments. Past test results, applicable rules, potential emissions, location of source, and past compliance history play a factor in setting the testing frequency. This permit requires testing to measure the PM10 emission rate (lb/hr) from EQUI 20 every 36 months. This frequency was chosen because past test results have ranged from about 25% of the limit to about 56% of the limit (with older tests in excess of the limit).


PM10 ≤ 15.0 lb/hr 3-hour average under Operating Scenario 2


None Operating scenario 2 (carbonation process bypass) is a non-standard operating condition that usually only occurs when the facility is not producing sugar. In this operating condition, all of the vertical lime kiln emissions are vented to the vertical lime kiln stack (STRU 33). It is unreasonable to require performance testing under these operating conditions.

Daily and periodic inspections, visual dust accumulation, pressure drop, operation and maintenance, corrective actions, and recordkeeping

The primary monitoring approach for this fabric filter involves daily visual inspections of the area surrounding the fabric filter exhaust for dust accumulation. This alternative fabric filter monitoring approach was chosen because the fabric filter vents internally (which renders visible emissions checks infeasible), and because the fabric filter is not equipped with gauges for measuring pressure drop. The permit has been written to require pressure drop monitoring as the primary monitoring approach if the unit is equipped with gauges for measuring pressure drop.

Weekly and periodic inspections, visible emissions, operation and maintenance, corrective actions, and recordkeeping

The ash silo/removal system (EQUI 88) is anticipated to have relatively low particulate matter emissions due to the boiler ash moisture content (estimated to be greater than 15% moisture). Weekly visible emissions checks are adequate to have a reasonable assurance of compliance, because the absence of visible emissions is indicative of the wet multi-stage cyclone and ash silo/removal system operating as designed.

The visible emissions (VE) check requirement frequency of once per week was chosen due to the physical challenges associated with performing the VE checks for this wet cyclone.

Multiclone





EQUI 17 is a large PSEU under CAM, so TREA 37 is subject to monitoring 4 times per hour. This is accomplished using continuous pressure drop monitoring.


Approved Replicable Methodology (ARM) or protocol for resetting the Pressure Drop limits: Per MPCA guidance, when the initial control equipment parameters are known or can reasonably be determined upfront AND where the permit includes periodic testing which will re-set the parameters, the permit should contain the limit as well as an ARM or protocol for revising the limits through testing. In this instance, as long as the Permittee is implementing the ARM as required by the permit, the permit does not need to be reopened to revise the control equipment parameter limits. The Notice of Compliance that approves the new limits using an ARM will be filed with the permit in OnBase. Every level of permit action (from admin to major) can be used to incorporate revised parameter limits that were approved via an ARM.

The establishment or revision of the ARM requires a major amendment process under Minn. R. 7007.1500, likely triggering one or all of: subp. 1(A) (revision to monitoring), and 1(B) (case-by-base limit), and 1(C) (used for assuring compliance with a limit taken to avoid an applicable requirement).

2 EQUI 1, EQUI 2, and EQUI 16 each have a certified COMS installed. These COMS will be used to demonstrate compliance with the opacity standard of Minn. R. 7011.0510, subp. 2.

3 The EQUI 1 (Boiler #1), EQUI 2 (Boiler #2), and EQUI 16 (Boiler #3) SO2 limit of 1.0 lb/MMBtu has been removed from the permit. No future SO2 performance tests are required, because the compliance with the applicable SO2 performance standard under Minn. R. 7011.0510 (4.0 lb/MMBtu when burning coal, 2.0 lb/MMBtu when burning diesel fuel) is demonstrated through fuel sulfur content limits and associated monitoring and recordkeeping.

4 Performance tests are required annually (within 13 months of previous test date), except that if the results from performance tests required under 40 CFR pt. 63, subp. DDDDD are ≤ 75% of the emission limit for two consecutive years, performance tests may be conducted every third year (within 37 months of previous test date), as specified in 40 CFR §63.7515(b).

5 Process weight rate-based limit. 6 EQUI 3 (Pulp Pellet Cooler) PM and PM10 performance test frequency increased from every 60 months to every 36 months due to 09/08/2010 test result ( > 60% of the limit).

3.9 40 CFR pt. 63, subp. DDDDD Operating Limits 40 CFR pt. 63, subp. DDDDD requires testing of filterable PM, hydrogen chloride (HCl), mercury (Hg), and carbon monoxide (CO) on an annual or 3-year basis, depending on the results of the most recent performance tests. During each test, operating limits must be confirmed or reestablished. Tables 15, 16, and 17 below provide a summary of the operating limits for each boiler that have been set by the most recent performance tests for each pollutant. Table 15.

3.10 New Electrostatic Precipitator (ESP) Opacity Excursion Levels

During the last permit term, a malfunction of the Boiler #3 ESP led to a non-compliant performance test for this boiler. During the October 31, 2017 boiler #3 filterable PM performance test when the ESP was malfunctioning, the hourly average opacity was 9.77% and the three-run average measured filterable PM emission rate was 21.2 lb/hr and 0.103 lb/MMBtu heat input. The applicable air dispersion modeling-based PM/PM10 emission rate limits for each boiler are 15.0 lb/hr (including condensable PM), and the applicable filterable PM emission rate limit for each boiler under 40 CFR pt. 63, subp. DDDDD is 0.040 lb/MMBtu heat input. In order to ensure effective operation of the ESPs for all three boilers, opacity excursion levels (under the Compliance Assurance Monitoring Rule) of 7.0% opacity on a 3-hour rolling average have been added to the permit. The averaging basis of a 3-hour rolling average was chosen, because this is consistent with the averaging basis of the PM10 air dispersion modeling-based emission rate limit. In general, the boilers typically operate well below 7.0% opacity. Based on the opacity data obtained during recent filterable PM performance tests, there is reasonable assurance that the Permittee will be in compliance with all applicable PM, PM10, and filterable PM emission limits when the boilers are operating at or below 7.0%. If the 3-hour average opacity level is above 7.0%, the Permittee is required to take corrective actions. A plot of opacity (%) vs. filterable PM emission rate (lb/hr) is shown in Figure 1 below.


Figure 1. Opacity (%) vs. Filterable PM Emission Rate (lb/hr) [All Boilers]

3.11 Tempo Data Discrepancies Due to limitations with the Tempo database, potential-to-emit (PTE) data can only be entered up to 12 decimal places. Many of the hazardous air pollutant compounds for the anaerobic digester flare and equalization pond flare were not entered in the database because they have emission rates less than 0.5 x 10-12 lb/hr (when rounded to the nearest 12th decimal place, the value rounds to zero). The PTE calculations for these compounds are still included in the calculations spreadsheets, and the emissions of these compounds are still included in the total hazardous air pollutant sum.

3.12 Insignificant activities American Crystal Sugar - Moorhead has several operations which are classified as insignificant activities under the MPCA’s permitting rules. These are listed in Appendix A to the permit. Additionally, there are two (2) fuel oil storage tanks and a gasoline storage tank which qualify as insignificant activities that are not required to be listed (Minn. R. 7007.1300, subp. 2(E)(3)-(4)). The fuel oil storage tanks have each been equipped with submerged fill pipes, as required by Minn. R. 7011.1505, subp. 3(B). The gasoline storage tank is not subject to Minn. R. 7011.1505. The permit is required to include periodic monitoring for all emissions units, including insignificant activities, per EPA guidance. The insignificant activities at this Facility are only subject to general applicable requirements. Using the criteria outlined earlier in this TSD, the following table documents the justification why no additional periodic monitoring is necessary for the current insignificant activities. See Attachment 1 of this TSD for PTE information for the insignificant activities.

Individual units with potential emissions less than 2000 lb/year of certain pollutants

Indirect-Heating Space Heaters and Pressure Washers PM ≤ 0.4 lb/MMBtu Opacity ≤ 20% with exceptions SO2 ≤ 2.0 lb/MMBtu (applies to liquid fuel units) (Minn. R. 7011.0515) Direct-Heating Space Heaters PM, variable depending on airflow Opacity ≤ 20% with exceptions (Minn.

R. 7011.0715) Pressed Pulp Overflow Storage Pad Opacity ≤ 5% from handling operation fugitive emissions Opacity ≤ 10% from truck loading station fugitive emissions (Minn. R. 7011.1005)

These are sixteen (16) natural gas-fired space heaters (5.76 MMBtu/hr total), four (4) propane-fired space heaters (0.16 MMBtu/hr total), two (2) kerosene-fired space heaters (0.35 MMBtu/hr total), one (1) waste oil-fired space heater (0.24 MMBtu/hr), six (6) natural gas-fired pressure washers (2.64 MMBtu/hr total), four (4) mineral spirits parts washing stations, a pressed pulp overflow storage pad, a wastewater treatment system, a pressed mud landfill, beet storage pads, and nineteen (19) non-fuel storage tanks. For the natural gas, propane, kerosene, and waste oil combustion units, based on the fuels used and EPA published emissions factors, it is highly unlikely that they could violate the applicable requirements. In addition, many of these units are operated and vented inside a building, so testing for PM or opacity is not feasible. For the pressed mud landfill, beet storage pads, and pressed pulp overflow storage pad, based on material moisture content, it is highly unlikely that they could violate the applicable requirements. It is not anticipated that the solvent parts washer, storage tanks, or wastewater treatment clarifier would emit any particulate emissions.


3.13 Permit organization In general, this permit meets the MPCA Tempo Guidance for ordering and grouping of requirements as well as the use of permit appendices. The permit contains two groups, COMG 1 (Sugar Silos), and COMG 4 (Boilers #1, #2, and #3 Used Oil Limitations). The use of groups in these instances was necessary, because the limits contained in these groups apply collectively to each group of units and associated monitoring and recordkeeping is performed on a group-basis (rather than on a per-unit basis). The requirements for 40 CFR pt. 63, subp. ZZZZ, 40 CFR pt. 63, subp. DDDDD, and the associated General Provisions in 40 CFR pt. 63, subp. A are included in the permit as described below. For these rules, limits, submittal/actions (such as reporting and performance testing requirements), and continuous opacity monitor and parametric monitor requirements are included individually in the permit like the other standards. For the remaining portions of the rule, a requirement in Section 5 of the permit lists the citations of all of the applicable parts of the standard along with a reference to the permit appendix where the full text of the standard is included. 40 CFR pt. 63, subp. ZZZZ, 40 CFR pt. 63, subp. DDDDD, and 40 CFR pt. 63, subp. A are included in Appendices F, G, and H, respectively. One item that should be noted is that certain emission limitations and applicable requirements have been listed at the stack subject item (STRU) level. Since many of the emission rate limits derived from PSD air dispersion modeling were meant to apply to the collective emissions from multiple units venting to an individual stack, it was appropriate to list these emission rate limits at the STRU subject items instead of the EQUI (emission unit) subject items in the permit. In the case of the lime kiln, which primarily vents emissions to two different stacks, the STRU subject items were used to distinguish individual air dispersion modeling-based emission limits and associated stack testing requirements for each of these stacks.

4. Permit fee assessment This permit action is the reissuance of an individual Part 70; therefore, no application fees apply under Minn. R. 7002.0016, subp. 1 to the changes that are covered by the reissuance application. However, the permit action rolls in two additional administrative amendment applications, a minor amendment application, and a major amendment application to which fees do apply. Attachment 11 to this TSD contains the MPCA’s assessment of Application and Additional Points used to determine the permit application fee for this permit action as required by Minn. R. 7002.0019. The action also includes the incorporation of two NESHAPs; however, these are existing standards that applied to the facility and are not chargeable activities (i.e., the standard was not triggered by the modifications requested in the permit applications – it falls under a permit reopening being incorporated in the reissuance).

5. Conclusion Based on the information provided by American Crystal Sugar - Moorhead the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit No. 02700001-101 and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

For the purposes of air dispersion modeling, the short-term (1- to 3-hour average) emission rate for sub-bituminous coal combustion is assumed to be 1.23 lb/MMBtu based on the coal sulfur variability analysis (Attachment 4 to the TSD).r Biogas SO2 Calculation:

Ideal gas law: pV = nRT --> rearrange to calculate n/V (number of moles of biogas per 1 cubic foot): n/V = p/RTR = 0.08206 L·atm·g-mol-1·K-1

Assume P = 1 atm, T = 294 K, 0.45% H2S, 589 Btu/ft3

2H2S + 3O2 --> 2SO2 + 2H2O (1 mol SO2 : 1 mol H2S)

n/(1 L) = (1 atm) / ( (0.08206 L·atm·g-mol-1·K-1) x (294 K) ) = 4.14E-02 g-mol biogas/L biogasn/(1 ft3) = 0.0414 mol/L x (28.317 L / ft3) = 1.17E+00 g-mol biogas/ft3 biogas

lb SO2/ft3 biogas = (0.0045 H2S) x (n/(1 ft3)) x (64.06 g/g-mol SO2) / (453.5923 g/lb) = 7.45E-04 lb SO2/ft

It is assumed that the PM and PM10 emission rates measured during the 11/27/2007 performance test are representative of the entire lime kiln PM emissions (i.e. all lime kiln exhaust gases were routed through the dual cyclones during the test).

Description of Vertical Lime Kiln Operating Scenario 3: During operating scenario 3, all lime kiln exhaust gases are routed through the gas washer, followed in series by one of the carbonation process tanks. This operating scenario would only be utilized for as long as it would take to restore the dual cyclones to their normal operation.

Pressed Pulp Overflow Storage Pad

The pressed pulp overflow pad is used for temporary strorage of pressed pulp if there is

an upset to the pulp dryers and the pulp cannot be dired. This material is sold as a beneficial

use byproduct to local agricutural operations, typically as animal feed.

Due to the high moisutre of the pressed pulp, which is greater than 70%, particulate emissions

are negligible.

Wastewater Treatment System/Clarifier

All emissions from the wastewater treatment system are calculated as being emitted from the

anerobic digester, EQUI78. The primary clarifier has minimal biologic activity due to aerobic

conditions, cold temperatures and minimal residence time. As a wet process, no emission

of particulate matter are generated. VOC emissions are neglible, as stated above.

Pressed Mud Landfill

The pressed mud landfill is a temporary storage pile operation where mud from the primary

clarifier is dewatered prior to land application off-site (i.e., reapplication to fields). This is a high

moisture process that generates neglible particulate emisisons. Biologic activity is minimal due to

Beet Storage Pads

Beets that are stored on-site on the beet storage pads have a small amount of wet soil (tare)

that adhere to the beet. The beet storage pads are filled during one month of intense harvest

in the fall. After freezing throughout the winter, the beets on the storage bads are processed in

the factory during the spring months. Both wet fall condtions and frozen winter conditions

preclude the emission of particulate matter. However, in order to provide a conservative

assessment of emissions the total weight of beets stored was used (1,050,000 tons).

November 30, 2011 Mr. Doug Emerson Environmental Affairs Manager American Crystal Sugar Company 1700 North 11th Street Moorhead, MN 56560 Re: American Crystal Sugar Company Moorhead Factory 2012 Pulp Press Installation Project

Environmental Review Dear Mr. Emerson, Following is an air emissions permit applicability analysis for the proposed 2012 pulp press installation project at the American Crystal Sugar Company (ACSC) Moorhead (MHD) factory. This information has been provided for your files to document projected actual emission increase levels and substantiate that no permit application is needed prior to project implementation. Permit Requirements The MHD factory currently operates under Air Emission Permit No. 02700001-011 and is classified as a major stationary source under the Federal New Source Review Prevention of Significant Deterioration (PSD) regulations (40 CFR 52.21) and Title V Operating Permit rules (40 CFR 70). Because the MHD factory is a major stationary source under PSD rules, it is necessary to perform an applicability analysis to determine if a proposed physical modification would result in a significant emission increase of regulated pollutants on an annual basis (40 CFR 52.21(b)(23)(i) and (b)(40)), which would trigger major modification preconstruction review requirements. In order to demonstrate that any increase in emissions of regulated air pollutants would be minor with respect to applicable rules, the following project analysis was performed. Proposed Modification The proposed modification would be implemented during the 2012 intercampaign period and would consist of installing an additional Stord 2500 Pulp Press (or equivalent). Piers, foundations, conveying and other necessary equipment would also be installed as part of the project. The installation of the Stord 2500 press is anticipated to increase the overall pulp pressing capacity of the MHD facility by approximately 30%. The higher capacity would allow the overall collection of pulp presses at MHD to run at lower speeds, resulting in decreased pressed pulp moisture of approximately 1.5%. The decrease in pressed pulp moisture would allow the recovery of additional sugar to the production process by capturing sugar that was previously

retained in the pulp. An additional benefit of the project would be decreased operating costs of the pulp dryers due to a reduction in moisture loading to the dryers, which reduces the evaporation demand. Emission Calculations In order to determine if a significant net emission increase would occur, PSD rules allow for two different emission increase applicability tests: the actual-to-projected-actual applicability test and the potential-to-actual applicability test. Because the potential-to-actual applicability test does not allow for the ability to account for normal campaign downtime, which results in overestimating project related emission increases, the actual-to-projected-actual emission test was the focus for the proposed project. In accordance with 40 CFR 52.21(a)(2)(iv)(c), a significant emission increase of a regulated pollutant is projected to occur if the difference between the projected actual emissions and the baseline actual emissions equals or exceeds the significant amount for that pollutant. There would be no direct emissions associated with the Stord 2500 pulp press and ancillary feed equipment. The press would be driven by an electric motor and the high moisture content of the handled pulp would preclude any direct particulate emissions. The increased pulp pressing capacity at MHD is not anticipated to result in any increase to the overall slice rate, or production capability, of the factory. The higher pulp pressing capacity will only allow increased moisture recovery at the current factory slice rate. Process operations downstream from the pulp presses such as evaporators and sugar centrifugals, dictate the overall factory production capacity. The minor amount of additional moisture gained from the increased pressing capacity will be able to be accommodated by the sugar production end of the factory, however, these process operations provide a bottleneck for any overall increase in slice rate and would need to be physically modified in order to allow increased production of sugar. Because the sugar end bottlenecks prevent an increase in overall slice rate, the pulp drying and handling equipment downstream from the pulp presses would not be significantly impacted by the proposed modification. There would be a reduction in energy demand for the pulp dryers due to lowered evaporation requirements. Additionally, during some periods of the campaign, it is not possible for the pulp dryers to process all of the wet pulp produced by the MHD factory. Excess wet pulp is stockpiled and discarded as necessary. The increased pulp pressing capacity resulting from the proposed project will reduce the overall moisture level of the pulp allowing a small amount (approximately 0.4%) of additional pulp that was previously discarded to be processed in the dryers during certain periods of the campaign. However, even with the slight increase in amount of pulp processed, the overall reduction in pulp moisture will result in a fuel savings, which would directly reduce emissions associated with the drying process. Impacts to the pelletization process would be negligible.


Page 3

Emission increases associated with the proposed project would be experienced as a result of increased sugar production enabled by the recovery of additional sugar containing moisture from the pressed pulp. Based on process calculations provided by MHD engineering staff, it is estimated that the increased juice recovery would result in an annual sugar recovery of 13,984 hundredweight (cwt). The calculation is based on both frozen and non-frozen sugar beet processing characteristics at an average production rate of 251 tons per hour. While the production rate varies somewhat depending on various processing variables, 251 tons per hour is representative of annual worst-case maximum factory operations. Additionally, the calculated recovery rate does not include normal production loss and sugar recovery potential, but instead assumes 100 percent of the sugar available in the additional juice is recovered to provide a worst-case maximum estimate. The projected actual emission increase calculation process for the proposed pulp press installation involved two steps. First, actual emissions of affected sources during the baseline period (2007/2008) were calculated and compared to the average wholesale sugar production value of 5,068,840 cwt per year during the same period. This resulted in an emission factor based on the amount of sugar produced. Second, the calculated production increase from recovered moisture was used in conjunction with the calculated emission factor to extrapolate actual emission increases resulting from the proposed project. As indicated previously, the total calculated production increase was 13,984 cwt, or about 0.3% over pre-modification production operations. The emission calculations are based on the assumption of a linear increase in emissions associated with production increases. It should be noted that the decrease in fuel consumption and subsequent emission reductions from the pulp processing operations would likely offset any emission increases resulting from increased sugar production. However, in order to provide a conservative assessment of regulatory applicability it was assumed that all production increases would result in direct emission increases. Table 1 provides a summary of the estimated emissions increases.

Considering the negligible projected emission increases listed in Table 1, the calculation of more detailed emission estimates for lead and acid gases is not warranted and the project has been determined to be minor with respect to PSD modification applicability. In accordance with PSD rules, actual emissions that are unrelated to the particular project, including any increase in utilization due to product demand growth, can be excluded from the net emission increase calculations (40 CFR §52.21(b)(41)(ii)(c)). In the event that a future larger harvest takes place, additional processing requirements such as increased annual utilization could be excluded from the calculations due to the unrelated nature to the present project. Recordkeeping The projected actual emissions are less than fifty percent of the significant levels for all pollutants. Therefore, no recordkeeping is required by PSD rules (40 CFR 52.21(r)(6)) since there is no “reasonable possibility”, as defined by 40 CFR 52.21(r)(6)(vi)(b), that the project is actually major. Although no recordkeeping is required, it is recommended that ACSC keep this applicability analysis on file. Both the EPA and the MPCA have the right to request this information at any time. If you have any questions or require additional information, please do not hesitate to contact me at (763) 278-5905. Sincerely, HDR Engineering, Inc.

TFAC 3 1240

PERMIT SHIELD: Subject to the limitations in Minn. R. 7007.1800, compliance with the conditions of this permit

shall be deemed compliance with the specific provision of the applicable requirement identified in the permit as

the basis of each condition. Subject to the limitations of Minn. R. 7007.1800 and 7017.0100, subp. 2,

notwithstanding the conditions of this permit specifying compliance practices for applicable requirements, any

person (including the Permittee) may also use other credible evidence to establish compliance or noncompliance

with applicable requirements.

This permit shall not alter or affect the liability of the Permittee for any violation of applicable requirements prior

to or at the time of permit issuance. [Minn. R. 7007.1800(A)(2)]

TFAC 3 1270

Comply with Fugitive Emission Control Plan: The Permittee shall follow the actions and recordkeeping specified in

the fugitive dust control plan in Appendix C of this permit. If the Commissioner determines the Permittee is out

of compliance with Minn. R. 7011.0150 or the fugitive 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. [Minn. R. 7007.0100, Minn. R. 7007.0800, subp. 2, Minn. R. 7009.0020, Minn. R. 7011.0150, Minn.

R. 7011.1110, Minn. Stat. 116.07, subd. 4a]

TFAC 3 1280

These requirements apply if a reasonable possibility (RP) as defined in 40 CFR Section 52.21(r)(6)(vi) exists that a

proposed project, analyzed using the actual-to-projected-actual (ATPA) test (either by itself or as part of the

hybrid test at Section 52.21(a)(2)(iv)(f)) and found to not be part of a major modification, may result in a

significant emissions increase (SEI). If the ATPA test is not used for the project, or if there is no RP that the

proposed project could result in a SEI, these requirements do not apply to that project. The Permittee is only

subject to the Preconstruction Documentation requirement for a project where a RP occurs only within the

meaning of Section 52.21(r)(6)(vi)(b).

Even though a particular modification is not subject to New Source Review (NSR), or where there isn't a RP that a

proposed project could result in a SEI, a permit amendment, recordkeeping, or notification may still be required

by Minn. R. 7007.1150 - 7007.1500. [Minn. R. 7007.0800, subp. 2, Title I Condition: 40 CFR 52.21(r)(6) and Minn.

R. 7007.3000]


TFAC 3 1300

Preconstruction Documentation -- Before beginning actual construction on a project, the Permittee shall

document the following:

1. Project description

2. Identification of any emission unit whose emissions of an NSR pollutant could be affected

3. Pre-change potential emissions of any affected existing emission unit, and the projected post-change potential

emissions of any affected existing or new emission unit.

4. A description of the applicability test used to determine that the project is not a major modification for any

regulated NSR pollutant, including the baseline actual emissions, the projected actual emissions, the amount of

emissions excluded due to increases not associated with the modification and that the emission unit could have

accommodated during the baseline period, an explanation of why the amounts were excluded, and any

creditable contemporaneous increases and decreases that were considered in the determination.

The Permittee shall maintain records of this documentation. [Minn. R. 7007.0800, subps. 4-5, Minn. R.

7007.1200, subp. 4, Title I Condition: 40 CFR 52.21(r)(6) and Minn. R. 7007.3000]

TFAC 3 1310

The Permittee shall monitor the actual emissions of any regulated NSR pollutant that could increase as a result of

the project and that were analyzed using the ATPA test, and the potential emissions of any regulated NSR

pollutant that could increase as a result of the project and that were analyzed using potential emissions in the

hybrid test. The Permittee shall calculate and maintain a record of the sum of the actual and potential (if the

hybrid test was used in the analysis) emissions of the regulated pollutant, in tons per year on a calendar year

basis, for a period of 5 years following resumption of regular operations after the change, or for a period of 10

years following resumption of regular operations after the change if the project increases the design capacity of

or potential to emit of any unit associated with the project. [Minn. R. 7007.0800, subps. 4-5, Title I Condition: 40

CFR 52.21(r)(6) and Minn. R. 7007.3000]

TFAC 3 1320

The Permittee must submit a report to the Agency if the annual summed (actual, plus potential if used in hybrid

test) emissions differ from the preconstruction projection and exceed the baseline actual emissions by a

significant amount as listed at 40 CFR Section 52.21(b)(23). Such report shall be submitted to the Agency within

60 days after the end of the year in which the exceedances occur. The report shall contain:

a. The name and ID number of the Facility, and the name and telephone number of the Facility contact person.

b. The annual emissions (actual, plus potential if any part of the project was analyzed using the hybrid test) for

each pollutant for which the preconstruction projection and significant emissions increase are exceeded

c. Any other information, such as an explanation as to why the summed emissions differ from the

preconstruction projection. [Minn. R. 7007.0800, subps. 4-5, Title I Condition: 40 CFR 52.21(r)(6) and Minn. R.

7007.3000]

TFAC 3 1330

The Permittee shall comply with National Primary and Secondary Ambient Air Quality Standards, 40 CFR pt. 50,

and the Minnesota Ambient Air Quality Standards, Minn. R. 7009.0010 to 7009.0090. Compliance shall be

demonstrated upon written request by the MPCA. [Minn. R. 7007.0800, subp. 2(A) & (B), Minn. R. 7009.0020-

7009.0090, Minn. Stat. 116.07, subd. 4a(a)]

TFAC 3 1370

Circumvention: Do not install or use a device or means that conceals or dilutes emissions, which would otherwise

violate a federal or state air pollution control rule, without reducing the total amount of pollutant emitted.

[Minn. R. 7011.0020]

TFAC 3 1380

Air Pollution Control Equipment: Operate all pollution control equipment whenever the corresponding process

equipment and emission units are operated, except as otherwise authorized by this permit. [Minn. R. 7007.0800,

subp. 16(J), Minn. R. 7007.0800, subp. 2]

TFAC 3 1390

Operation and Maintenance Plan: Retain at the stationary source an operation and maintenance plan for all air

pollution control equipment. At a minimum, the O & M plan shall identify all air pollution control equipment and

control practices and shall include a preventative maintenance program for the equipment and practices, a

description of (the minimum but not necessarily the only) corrective actions to be taken to restore the

equipment and practices to proper operation to meet applicable permit conditions, a description of the

employee training program for proper operation and maintenance of the control equipment and practices, and

the records kept to demonstrate plan implementation. [Minn. R. 7007.0800, subp. 14, Minn. R. 7007.0800, subp.

16(J)]


TFAC 3 1410

Operation Changes: In any shutdown, breakdown, or deviation the Permittee shall immediately take all practical

steps to modify operations to reduce the emission of any regulated air pollutant. The Commissioner may require

feasible and practical modifications in the operation to reduce emissions of air pollutants. No emissions units

that have an unreasonable shutdown or breakdown frequency of process or control equipment shall be

permitted to operate. [Minn. R. 7019.1000, subp. 4]

TFAC 3 1420

Fugitive Emissions: Do not 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. [Minn. R. 7011.0150, Minn. R. 7011.1110]

TFAC 3 1430

The Permittee shall clean up commodities spilled on the driveway and other facility property as required to

minimize fugitive emissions to a level consistent with RACT (reasonably available control technology). [Minn. R.

7011.1005, subp. 1(A)]

TFAC 3 1440

The Permittee may not operate or maintain the facility such that it creates a public nuisance. If the commissioner

determines that operation or maintenance of a commodity facility creates a public nuisance, the commissioner

may require the Permittee to take measures necessary to eliminate the nuisance. [Minn. R. 7011.1010]

TFAC 3 1450

Visible Emissions: The Permittee shall conduct visible emissions (VE) readings at the Pellet Rail Loadout Spout at

least once each day of operation while pellets are being loaded into a railcar. The visible emissions check must be

conducted from a location perpendicular to the plume and at least 15 feet away during daylight hours. The

observer shall select a position where the sun is not directly in the observer's eyes. If the observations cannot be

conducted due to weather conditions, the date, time, and specific weather conditions must be recorded. If after

one year of VE readings no visible emissions are recorded, the Permittee may reduce the frequency to once each

week of operation while pellets are being loaded into a railcar.

Protocol for Resetting the Pressure Drop Range Limit: The Permittee shall conduct performance testing to

measure the PM and PM10 emission rate as required elsewhere in this permit. If the established Pressure Drop

Range Limit is to be reset, the reset shall be based on the pressure drop values recorded during the most recent

MPCA-approved performance test where compliance was demonstrated.

During the performance test, the Permittee must continuously monitor the pressure drop. The Permittee shall

calculate the average pressure drop based on the average exhibited over all three compliant test runs. Downtime

of 15 minutes or more is not to be included as operating time.

The established Pressure Drop Range Limits shall be reset as follows:

- if the 3-hour average pressure drop recorded during the test is within the established range, it shall not be reset

and the established values remain the Pressure Drop Range Limit; or

- if the 3-hour average pressure drop is below the minimum value of the established range, the new minimum

value shall be reset to 50% of the average pressure drop from the test. The maximum value shall be decreased by

the same amount to maintain the pressure drop range; or

- if the 3-hour average pressure drop is above the maximum value of the established range, the new maximum

value shall be reset as the average pressure drop from the test plus 10%. The minimum value shall be increased

by the same amount to maintain the pressure drop range.

The pressure drop range is equal to the maximum value (upper bound) minus the minimum value (lower bound).

Ongoing compliance with the Pressure Drop Range Limit will be determined using the same data acquisition and

reduction as was used during the performance test. The new Pressure Drop Range Limit shall be effective upon

receipt of the Notice of Compliance letter that approves the test results and shall be incorporated into the permit

when the permit is next amended. [Minn. R. 7017.2025, Title I Condition: 40 CFR 52.21(k)(modeling) & Minn. R.

Notwithstanding the Protocol detailed above, the MPCA reserves the right to set operational limits and

requirements as allowed under Minn. R. 7017.2025. If the MPCA sets limits, the new limits shall be implemented

upon receipt of the Notice of Compliance letter that notifies the Permittee of preliminary approval. The limits set

according to Minn. R. 7017.2025 are final upon issuance of a permit amendment incorporating the change.

September 11, 2015 Air Quality Permit Technical Advisor Minnesota Pollution Control Agency 520 Lafayette Road North St. Paul, MN 55155 Re: American Crystal Sugar Company – Moorhead Request for Extension of Compliance with 40 CFR § 63, Subpart DDDDD. Dear Air Quality Permit Technical Advisor:

American Crystal Sugar Company (ACSC) currently operates a sugar beet processing plant located in

Moorhead, MN, under Title V Air Emissions Permit No. 02700001-011. The processing plant is

classified as an existing major source of hazardous air pollutants and is subject to 40 CFR § 63,

Subpart DDDDD - National Emission Standards for Hazardous Air Pollutants for Major Sources:

Industrial, Commercial, and Institutional Boilers and Process Heaters.

In accordance with § 63.7495, a new or existing boiler or process heater must comply with the

requirements of Subpart DDDDD no later than January 31, 2016, except as provided in § 63.6(i),

Extension of Compliance with Emission Standards. The extension allowance, specifically included in

§ 63.6(i)(4)(i)(A), states that the owner or operator of an existing source who is unable to comply with a

relevant standard may request that the Administrator (or State, when the State has been delegated the

authority to implement the emission standard) grant an extension allowing the source up to one (1)

additional year to comply with the standard, if such additional period is necessary for the installation of

controls. Such a request must be submitted in writing to the appropriate authority no later than 120

days prior to the affected source’s compliance date (October 3, 2015).

Upon review of the compliance requirements listed in Table 2 of § 63, Subpart DDDDD, it has been

determined that the ACSC Moorhead (MHD) facility will be subject to a mercury (Hg) emission limit of

5.7E-06 lb/MMBtu for units designed to burn solid fuel. An engineering analysis of existing control

equipment and past performance results has shown that the MHD facility may not be able to

demonstrate continuous compliance with the Hg emission limit for EU001, EU002 and EU003 without

physical modification to the current air pollution control equipment arrangement.

In order to ensure continuous compliance with the Subpart DDDDD Hg limitation with an adequate

compliance margin while maintaining operational flexibility, ACSC is proposing to install powdered

activated carbon (PAC) injection systems to control Hg emissions from EU001, EU002 and EU003.

Therefore, ACSC is requesting an extension of compliance for EU001, EU002 and EU003 to allow one

(1) additional year to comply with the standard as allowed under § 63.6(i).

In accordance with § 63.6(i)(6)(i), a request for a compliance extension shall include the following

information:

A description of the controls to be installed to comply with the standard;

of 3

A compliance schedule, including the date by which each step toward compliance will be

reached, including;

o The date by which on-site construction, installation of emission control equipment, or a

process change is planned to be initiated;

o The date by which on-site construction, installation of emission control equipment, or a

process change is to be completed; and,

o The date by which final compliance is to be achieved.

A conceptual engineering analysis was completed to evaluate engineering performance tests from all

ACSC facilities (including MHD), to estimate capital and operating costs for various PAC injection

technologies, to obtain coal Hg data from fuel suppliers and to determine appropriate options for

compliance with Subpart DDDDD requirements. Based on the results of the engineering analysis it has

been proposed that the current air pollution control systems at MHD be augmented by installation of a

PAC Injection system.

The ACSC MHD facility currently utilizes electrostatic precipitators to control particulate emissions.

There is currently no dedicated air pollution control equipment to target Hg emissions. The only Hg

control experienced at the MHD facility is native capture of Hg in the unburned carbon and fly ash

during the combustion process, as well as any retention of Hg in the bottom ash. The proposed PAC

injection systems will be used to introduce activated carbon into the boiler flue gas after the air pre-

heaters and before the ESPs in a location that will provide a suitable mixing zone and proper residence

time to allow the carbon to adsorb available Hg in the flue gas. The existing ESPs will then remove the

carbon and adsorbed Hg from the flue gas, thereby reducing Hg to compliant levels. It is anticipated

that the low level of activated carbon introduced into the flue gas will allow EU001, EU002 and EU003

to maintain compliance with current PM emission limits.

Because of the campaign-based seasonal operation of the MHD facility, the period available for

construction is generally limited to the scheduled factory shutdown/maintenance period that typically

extends from late June to August of each year. Initial queries to equipment vendors during the

development of budgetary estimates and conceptual design indicate equipment lead times of

approximately 10 months for PAC injection systems. The long lead time is due in part to the high

demand of such systems for utilities regulated under the MATS rule as well as industrial sources

regulated under the Boiler MACT rule. The following schedule summarizes the proposed milestone

dates to implement the air pollution control equipment project.

Douglas Emerson Page 1 November 3, 2015 November 4, 2015 Douglas Emerson Environmental Affairs Manager American Crystal Sugar Company 101 North 3rd St. Moorhead, MN 56560 RE: Approval of Request for a One Year Extension for Compliance with 40 CFR pt. 63, subp.DDDDD Dear Douglas Emerson: On September 11, 2015 the Minnesota Pollution Control Agency (MPCA) received your written request, by electronic mail, for a one (1) year extension to the 40 CFR pt. 63, subp.DDDDD, mercury limitation compliance deadline of January 31, 2016 at 40 CFR § 63.7495(b) for boilers EU001, EU002, and EU003 at the American Crystal Sugar Company (ACSC) located in Moorhead, Minnesota (MHD). The MPCA received additional information from ACSC on October 12, 2015, in response to a phone conversation requesting additional information. Your extension request is based on the provision of 40 CFR § 63.6(i)(4)(i)(A). The September 11, 2015, letter stated that after conducting an engineering analysis of existing control equipment and past performance results, ACSC determined that the MHD facility may not be able to demonstrate continuous compliance with the mercury emission limit for EU001, EU002, and EU003 without physical modification to the current air pollution control equipment arrangement. That limit, 5.7E-06 lb per MMBtu of heat input, is from 40 CFR pt. 63, subp.DDDDD Table 2: Emission Limits for Existing Boilers and Process heaters for units burning solid fuel for mercury, which is referenced at 40 CFR § 63.7500(a)(1). The letter states that the MHD facility’s current control equipment does not target mercury emissions, and some sort of control equipment will have to be installed to ensure continuous compliance with the 40 CFR pt. 63, subp. DDDDD, Table 2, mercury limit. The September 11, 2015, letter also stated additional reasons for the extension, including (1) a limited period available for construction due to the seasonal operation of the MHD facility, and (2) indications of approximate lead times of 10 months needed for equipment for control systems due to the high demand of such systems for utility facilities and other industries with boilers trying to comply with rule deadlines. The letter stated that ACSC is proposing to install powdered activated carbon (PAC) injection systems to control the mercury emissions from EU001, EU002, and EU003 to achieve continuous compliance with the emission limit. In accordance with 40 CFR § 63.6(i)(6)(i), ACSC provided the necessary information for the compliance extension. A proposed compliance schedule including milestone dates for the installation of the control equipment was included in the request. ACSC is requesting a full year for the extension to allow flexibility to install the mercury emission reduction control equipment.

Douglas Emerson Page 2 November 3, 2015 Additional information was provided after a phone conversation on October 12, 2015, and an electronic mail was received by the MPCA containing information about a proposal to perform some baseline mercury samplings and a demonstration of other control equipment from Midwest Energy Emissions Corp. (ME2C) The information suggested a cost effective way to achieve the mercury emission limitation using a Sorbent Enhancement Additive (SEA) coupled with a proprietary backend carbon-based material sorbent similar to the PAC control equipment mentioned in the September 11, 2015, letter. The PAC injection system or the ME2C SEA system or the ME2C proprietary products system or any combination are to be installed, tested, and tuned to achieve compliance for the mercury emission limitation for 40 CFR pt. 63, subp. DDDDD. It is recommended that the highest mercury content fuel should be used at the time of testing for the proposed control equipment. By allowing the one (1) year extension for the MHD facility for EU001, EU002, and EU003, these units will be allowed to have a cost effective air control system that will minimize product use while achieving continuous compliance with the 5.7E-06 lb per MMBtu of heat input mercury emission limitation for 40 CFR pt. 63, subp. DDDDD. The one year extension would allow the facility some flexibility to construct and install equipment around the seasonal operation of the facility.

e Subbituminous coal is the only fuel burned in the boilers. This fuel is not classified as a secondary material.

Section III: Summary of Performance Test Results

Compliance with all emission limits is demonstrated through performance testing utilizing the heat

input-based emission limits. Because only a single type of fuel is combusted, fuel analysis to determine

compliance and/or establish operating limits is not required per 40 CFR63.7510(a)(2)(i). ACSCchooses

to comply with the PM limit and therefore does not address the alternative TSM emission limit.

Page 2 of4

An initial performance test was not yet completed for Mercury. ACSC requested and received a one-

year extension of the initial compliance date from the Minnesota Pollution Control Agency (MPCA) due

to the fact that physical modifications were required to install powdered activated carbon injection

systems to control potential mercury emission. The effective initial compliance date for mercury

emissions is January 31,2017.

Section IV: Additional Compliance Information

ACSCwill demonstrate ongoing compliance through periodic performance testing for each applicable

emission limit. Fuel analysis will not be used due to the fact that all ACSCboilers combust a single fuel

type.

Emissions averaging and efficiency credits through energy conservation will not be used for compliance

demonstration purposes.

In accordance with ~ 63.7550(b)(1), the first compliance report covering the period from January 31,

2016 to July 31,2016 must be postmarked and submitted no later than July 31, 2016. It is not possible

to certify compliance through July 31, 2016 and submit the report on the same day. The EPA proposed

a correction to this requirement, which was signed by EPAAdministrator, Gina McCarthy on November

5,2015. However, this proposed final rule was not yet published in the Federal Register and is therefore

not valid. ACSCbelieves it is the intent of the EPAto follow the proposed final rule that was signed by

the administrator. This rule states that the first semi-annual compliance report must cover the period

from January 31, 2016 to June 30 or December 31,2016, whichever is the first date that occurs at least

180 days after the initial compliance date of January 31, 2016, which would be July 29, 2016. Therefore,

the first compliance report is due postmarked in January 31, 2017 for the period from January 31,2016

to December 31,2016.

Section V: Deviations

ACSCinstalled and operated a continuous opacity monitoring system (CaMS) prior to the initial

compliance date of January 31, 2016. However, the certification of the CaMS was not completed during

the initial PM performance test. Because of the campaigned-based nature of ACSCoperations, the

Moorhead factory is currently shut down. Therefore the initial certification can not be completed within

180 days of January 31,2016. Operations will resume in mid-August of 2016 at the start of the fall

campaign. CaMS certification testing is scheduled for mid-August (or as soon as the boilers can sustain

a consistent load for testing purposes). Additionally, ACSChas contracted with a third-party vendor to

manage all compliance certifications, quarterly assessments and annual calibrations for the CaMS as

applicable.

These parameters are within the ranges defined in the approved test plan, more detailed information can be found with the final test report. In addition, please be advised of the following: 1. The following operating limit applies pursuant to Minn. R. 7017.2025, subp. 3. This limit will supersede

specific previous operating limits in the permit as stated below. The limit applies in addition to any other operating limit or requirement that already exists and does not serve to relax any other limit or requirement. Note: The Regulated Party has a Title V Part 70 Permit (Permit); therefore, the Permit will be re‐opened (under Minn. R. 7007.1600, subp. 1.D.) in order to add the new operating limit. This letter serves as the 30‐day notice of the MPCA’s intent to amend the Permit. This letter also grants preliminary approval to operate at the new rate until the new amendment is issued. Final approval will be given when the Permit is amended.

Emission Unit Operating Limit Vertical Lime Kiln EU004/EQUI20

Damper Position: less than or equal to 60% open at all times the unit is in operation.

The Regulated Party may not operate an emission unit at a less stringent rate than that listed in the table above unless it conducts a performance test at an alternate rate, the MPCA staff determines compliance at that rate for the emission unit, and a Notice of Compliance with approval to operate at the new rate is received. If an operating limit is exceeded, it must be reported in accordance with the deviation reporting requirements of Minn. R. 7007.0800, subp. 6(A).

2. The Emission Inventory rule, Minn. R. 7019.3000 to 7019.3100, requires the calculation of emissions

based on an established hierarchy. In the absence of Continuous Emission Monitor data meeting the requirements of Minn. R. 7019.3040, a performance test must be used. When a performance test for particulate matter, carbon monoxide, nitrogen oxides, sulfur oxides, volatile organic compounds or lead is conducted and meets the requirements of Minn. R. 7017.2001 to 7017.2060, the results must be used to calculate emissions, unless specified otherwise by Minn. R. 7019.3000 to 7019.3100. It is the Regulated Party’s responsibility to ensure the results of performance tests are accounted for in their annual emission inventory submittal. Note that the final decision to approve the emission factor for any given inventory year will be made by the Emission Inventory Coordinator.

Dear Mr. Doug Emerson: The Minnesota Pollution Control Agency (MPCA) has identified that your facilities are required by your air emission permits to submit ambient Hydrogen Sulfide (H2S) air quality data recorded at your facilities. Minnesota’s Ambient Air Quality Standards for H2S per Minn. R. 7009.0080 states:

Air Pollutant Level of Primary Standard Averaging Time Form of the Standard Hydrogen Sulfide 30 ppb by volume (42.0

micrograms per cubic meter)

30-minutes 30-minute average not to be exceeded more than two times in 5 consecutive days

Hydrogen Sulfide 50 ppb by volume (70.0 micrograms per cubic meter)

30-minutes 30-minute average not to be exceeded more than two times in a year

This letter acts as the MPCA’s written notification of our H2S standard policy for interpretation of this Rule, the identification of H2S exceedances and compliance determination. This policy is followed by the MPCA in the event of an H2S exceedance at your facility. Ambient H2S Air Quality Data Submittal All H2S data reports, whether requested by the MPCA or required under an MPCA permit, shall be submitted to the MPCA via the AQRoutineReport email at [email protected]. The data submittal shall be provided in an unlocked Excel format. The data will be reviewed by MPCA staff on annual basis, typically at the conclusion of the facility ambient air quality monitoring season. Each report shall contain all available data, including data measured in conditions not supported by the manufacturer of the monitoring equipment, or data that is believed to be from an offsite source. The MPCA considers this information the facility’s “raw data” and it is critical to evaluate measurement validity. No data point shall be omitted from the raw data for any reason. You are encouraged to provide notes for data points that you believe should be omitted from the MPCA compliance determination process. Interpretation of the data through the use of corresponding facility notes will be considered by MPCA technical staff on a case-by-case basis. The H2S standards are written in parts per million, and indicate that exceedances are greater than (not equal to) that figure. You are not required to submit data truncated to the parts per billion unit, however the MPCA will accept H2S data that is truncated to the parts per billion unit. Application of the Ambient H2S Air Quality Standards For H2S exceedance and violation purposes, the following standards will be counted accordingly:

mailto:[email protected]

American Crystal Sugar Company Page 2 June 21, 2018

30 ppb standard: Shall be evaluated based on an exceedance above 30 ppb 30-minute average. Allowable exceedances are exceedances that occur when there are fewer than two previous exceedances within the five previous calendar days, including the current calendar day. An exceedance shall be counted as a violation if there are at least two previous exceedances in the previous five calendar days including the current calendar day. Please note that we will no longer be considering a five day block of time when counting violations. If exceedances beyond a five day time period, each exceedance for each consecutive day shall be considered a violation. This is a health based standard, and shall be enforced based on the continuous exposure to the pollutant if present during consecutive days. This interpretation is not the same as a rolling time period. 50 ppb standard: Shall be evaluated based on an exceedance above 50 ppb 30-minute average more than two times in a calendar year. The first two exceedances of 50 ppb in a calendar year shall be considered allowable exceedances and any additional exceedances shall be counted as violations. Note: Exceedances and violations are counted separately for the 30 ppb and 50 ppb standards. For example, a reading above 50 ppb may be an allowable exceedance for the 30 ppb standard and simultaneously a violation of the 50 ppb standard. Data Analysis and Compliance Determination For H2S exceedance and violation purposes, the following conditions will be considered in the data analysis: Wind Speed: Data recorded when the wind speed is less than or equal to 2 mph are valid, but wind direction results are unreliable. Data will not be invalidated in these circumstances for enforcement purposes. Other information will be used by technical staff to determine if H2S results should be invalidated on a case-by case basis. Temperature: H2S data recorded when the air temperature is less than or equal to 35 degrees Fahrenheit shall be marked with the “AE” qualifier code, but all of the values must be provided in your data submittals. Any monitored exceedances with the “AE” qualifier code will not be considered when counting exceedances and violations for a facility unless there is confidence that the actual concentration was above a standard.

American Crystal Sugar: Moorhead, MN 2017 Industrial Ambient Air Monitoring Summary Report

Purpose American Crystal Sugar (ACS) worked with the MPCA to develop an ambient air monitoring plan for monitoring at their facility located at 2500 11th St. N. in Moorhead, MN to demonstrate attainment of state air quality standards for hydrogen sulfide (H2S). According to this plan, ACS is required to conduct ambient air monitoring at two monitoring sites near their facility. ACS is required to pass all MPCA quality assurance audits, meet monitoring completeness requirements, and meet state ambient air quality standards for H2S. More information about ACS’s air monitoring sites is available on page 4.

Summary of results This report summarizes air monitoring data collected near the ACS Moorhead facility in 2017. Air monitoring results are compared to the state air quality standards for H2S.

Quality assurance audits

MPCA Quality Assurance staff performed audits on all ACS monitors and each monitor passed all audits.

Completeness of monitoring

The table below shows the percent complete for each monitoring site in each month.

State Ambient Air Quality Standards

ACS met the 30 and 50 ppb H2S standards at their Moorhead facility in 2017. There were six exceedances of 30 ppb at site 2105, but none of those exceedances occurred within five days of a previous exceedance, so there is no violation of the 30 ppb standard. There were no exceedances of 50 ppb. The Minnesota Ambient Air Quality Standards and information about the exceedances of 30 ppb can be found on pages 2 and 3.

The following table describes Minnesota’s Ambient Air Quality Standards for hydrogen sulfide. Minnesota has two 30-minute standards. One standard requires that there are no more than two samples with concentrations greater than 30 ppb within any 5-day span during a calendar year to meet that standard. The other standard requires that there are no more than two samples with concentrations greater than 50 ppb during the calendar year to meet that standard.

Compliance Assurance Monitoring (CAM) Plan

Moorhead Sugar Beet Processing Plant

Moorhead, Clay County, Minnesota

1.0 Background

Compliance Assurance Monitoring (CAM) is required for affected sources under 40 CFR 64. A CAM plan

detailing the applicability and proposed monitoring approach of affected sources is required to be

included as part of the 40 CFR 70 (Title V) operating permit renewal process. The American Crystal Sugar

Company, Moorhead Sugar Beet Processing Plant located in Moorhead, Minnesota, was issued Air

Emission Permit No. 02700001‐001 on March 10, 1998. Valid for a period of five years, the original

operating permit had an expiration date of March 10, 2003. As part of the operating permit renewal

process, an operating permit renewal application and CAM plan was submitted in September of 2002

prior to the expiration date of the operating permit. Upon review of the operating permit renewal

application and CAM plan by Minnesota Pollution Control Agency (MPCA) contract staff, revisions to the

CAM plan were required and in incorporated into a revised CAM plan submitted in June of 2005. This

document comprises an additional revised CAM incorporating changes resulting from the current

operating permit renewal process.

The following bullet items identify the applicability requirements for CAM as applied to individual

emission units at a facility.

Emission unit is located at a major source that is required to obtain a Title V permit;

Emission unit is subject to emission limitation or standard for an applicable pollutant;

Emission unit uses a control device to achieve compliance with the emission limitation;

Potential pre‐control emissions of applicable pollutants (with limits) from the emission unit are

at least 100 percent of major source amount (100 tons per year); and,

Emission unit is not otherwise exempt and does not use a Continuous Emission Monitor (CEM)

for the applicable pollutant.

2.0 Applicability

Permitted emission units at the Moorhead Sugar Beet Processing Plant were evaluated to determine

which emission units have specific emission limitations and are equipped with control devices to

maintain compliance with the emission limitations. Pre‐control potential emissions were estimated for

those emission units that were determined to have both an emission limitation and associated control


equipment in order to determine if the uncontrolled emissions were greater than 100 percent of the

major source amount.

Due to a lack of more specific operating data, in most instances pre‐control potential emissions were

"back‐calculated" using the specific pollutant emission limitation in conjunction with the control

equipment efficiency stated in the original Title V permit application for the facility. Although "back‐

calculation" is not the preferred calculation approach, using this conservative method resulted in most

facility emission sources being subject to CAM requirements. A few sources were determined to be

exempt from CAM based on the conservative "back‐calculation"; however, these sources have very low

uncontrolled potential emission levels (approximately ¼ of the major source level) and there is a high

degree of confidence that the exempt sources are indeed minor with respect to uncontrolled emissions.

Based on the CAM applicability calculations, the following emission sources and associated control

equipment types were determined necessary to be included in the CAM plan. All sources except for

EQUI17, South Pulp Dryer, are classified as “other” emission sources with respect to CAM applicability.

EQUI17, South Pulp Dryer is classified as a “large” emission source due to post control PM and PM10

emissions greater than the major source threshold.

As indicated in Table 1, three different control equipment technologies were identified as necessary to

include in the CAM plan: fabric filter, cyclone (and multiclone), and electrostatic precipitator (ESP). The

following sections are organized by control technology type and detail the various monitoring

approaches and justifications for each control technology type.

3.0 Fabric Filter

The Moorhead Sugar Beet Processing Plant uses baghouses, or fabric filter technology, to collect

particulate matter (PM/PM10/PM2.5) generated from various material handling operations throughout

the facility. In general, sugar dryer and cooler, and various sugar handling and storage equipment. A


number of the sources are vented internally. The pulp dryers also utilize fabric filters, but in conjunction

with multiclone controls, therefore, the pulp dryers are addressed in a separate section of the CAM

plan.

Dust laden air is drawn through the fabric filters to capture particles entrained in the air. The fabric

filter provides filtration as well as acts as a support for the formation and accumulation of a filter cake

that provides for very high efficiency filtration.

As the particulate matter accumulates on the filter media and the filter cake is formed, the pressure

drop across the fabric filter increases. Although the filter cake increases collection efficiency, it also

restricts the airflow and increases energy requirements. For proper continuous operation of the fabric

filter, the filter media must be periodically cleaned or replaced.

Emission sources that utilize fabric filters for control include the following:

EQUI18, Sugar Dryer (Associated Equipment EQUI127)

EQUI19, Sugar Cooler (Associated Equipment EQUI128 – EQUI130)

EQUI65, Powdered Sugar (Associated Equipment EQUI131 – EQUI140)

EQUI15, Weibull Bin (Associated Equipment EQUI91 – EQUI93)

EQUI94, Rotex Screens (Associated Equipment EQUI95 – EQUI109)

EQUI124, Rail Loadout

3.1 Monitoring Approach

ranges, and performance criteria, are presented in Table 2.

3.2 Justification

The monitoring approach is consistent with the EPA CAM Technical Guidance Document, Section B. 1,

Fabric Filters, Item No. 1a. Fabric Filter for PM Control, (1/05). As indicated in the guidance, the fabric

filter sources are considered small pollutant specific emission sources (i.e., less than 100 tons per year

post‐control potential to emit); therefore, CAM does not require continuous monitoring with four or

more data points averaged over each hour.

The first indicator used to monitor baghouse operation is visible emissions. When the emission unit is

operating and weather permits, routine daily observations of visible emissions are performed and

recorded by plant personnel to monitor bag performance. The presence of visible emissions is directly

related to equipment performance. Visible emissions may signal equipment malfunction or bag failure.

Maintenance activities may also cause brief periods of visible emissions. Observed visible emissions will

be documented and reported, and corrective action will be initiated if necessary.

The second indicator used to monitor baghouse operation is inspection and maintenance. Baghouse

performance is monitored by routine inspections of equipment performed by plant personnel. All

excursions and maintenance activities will be documented and reported in a maintenance log.

Consistent with CAM guidance, no emission test correlation is provided because the proposed indicator

is "any visible emissions" and not a specific level, or range, of opacity. Compliance testing is not required

to establish a visible emission range to avoid potential emissions exceedences. Visible emission

monitoring as specified by the operating permit is adequate to have a reasonable assurance of

compliance and to ensure that the baghouse continues to operate properly and achieve the desired

control efficiency.


4.0 Cyclones

The Moorhead Sugar Beet Processing Plant uses cyclones, or centrifugal collectors, to collect particulate

matter (PM/PM10/PM2.5) generated from the lime kiln and pulp drying operations. The pulp dryers also

utilize fabric filters in conjunction with multiclone controls, therefore, the pulp dryers are addressed in a

separate section of the CAM plan.

A cyclone is a mechanical collector that uses inertia to separate particulate matter from a gas stream as

it spirals through the cyclone. The process air stream enters near the top of the cyclone and is forced

into a downward spiral because of the cyclone's shape and turning vanes. Centrifugal forces and inertia

cause the particles to move outward, collide with the outer wall, and then slide downward to the

bottom of the cyclone. Near the bottom of the cyclone, the air reverses its downward spiral and moves

upward in a smaller inner spiral. Cleaned air exits from the top and recovered particulate matter exits

from the bottom of the cyclone. A Multiclone is a series of cyclones, usually of varying size, for more

efficient removal of a broader spectrum of particulate matter.

Common operational problems experienced with cyclones and multiclones include erosion of cyclone

components that come into contact with high velocity particles; plugging of the dust outlet or the gas

inlet vanes; corrosion from contact with acid gases in the inlet gas stream; and air in‐leakage that affects

the inlet velocity and control efficiency of the cyclone.

Emission sources that utilize cyclone/multiclone control include the following:

4.2 Justification

The monitoring approach is consistent with the EPA CAM Technical Guidance Document, Section B.12,

Cylcones, Item No. 12b. Cyclone for PM Control, (1/05). As indicated in the guidance, the fabric filter

sources are considered small pollutant specific emission sources (i.e., less than 100 tons per year post‐

control potential to emit); therefore, CAM does not require continuous monitoring with four or more

data points averaged over each hour.


The first indicator used to monitor cyclone operation is differential pressure (DP) monitoring. A DP

gauge is used for measurement at each cyclone. Because DP across a cyclone is primarily a function of

velocity, it can be used as a surrogate for velocity measurements. Therefore, up to the pressure

differential that corresponds to the critical velocity, control efficiency increases with increasing pressure

differential.

DP observations are performed manually once per 24‐hour period when each unit is operating.

Excessive DP may indicate an accumulation of particulate matter within the system or other blockage

that inhibits control efficiency of the cyclone.

The second indicator used to monitor cyclone operation is inspection and maintenance. Proper

maintenance of the cyclone as specified by the manufacturer to maintain the physical integrity of the

device ensures proper operation and maximum product recovery. Cyclone performance is monitored by

routine inspections of equipment performed by plant personnel. All excursions and maintenance

activities will be documented and reported in a maintenance log.

In accordance with 40 CFR 64.4(d)(2) an owner or operator may submit indicator ranges that rely on

engineering assessments and other data provided that the owner or operator demonstrates that such

data makes compliance or performance testing unnecessary. The proposed DP ranges are based on

manufacturer recommendations and historical plant operation data. Furthermore the DP ranges were

reviewed, approved and listed as operational requirements in Air Emission Permit No. 02700001‐011 for

the Moorhead facility. Because the DP ranges were previously reviewed by regulatory staff and are

listed as a permit requirement, additional evaluation is not required. Previous performance testing

demonstrating compliance with applicable emission limits was completed for EQUI20 several times in

the past. Results of performance testing are on file at the Minnesota Pollution Control Agency (MPCA).

5.0 Multiclones and Fabric Filters (Series)

The Moorhead Sugar Beet Processing Plant uses multiclones and fabric filters operated in series to

collect particulate matter (PM/PM10/PM2.5) generated from the pulp drying operations. After passing

through the multiclones a portion of the exhaust gas passes through the baghouse to provide additional

control.

The operating principles of fabric filters were detailed in Section 3.0 and the operating principles of

cyclone/multiclones were detailed in Section 4.0.


Emission sources that utilize both multiclone and fabric filter control include the following:

EQUI17, South Pulp Dryer

EQUI22, North Pulp Dryer



ranges, and performance criteria, are presented in Table 4. EQUI17, South Pulp Dryer, is classified as a

“large” emission source. Therefore, CAM requirements necessitate continuous monitoring with four or

more data points averaged each hour. This additional requirement is reflected below in Table 4.

manufacturer recommendations and historical plant operation data. Furthermore the DP ranges were

reviewed, approved and listed as operational requirements in Air Emission Permit No. 02700001‐011 for


the Moorhead facility. Because the DP ranges were previously reviewed by regulatory staff and are

listed as a permit requirement, additional evaluation is not required. Previous performance testing

demonstrating compliance with applicable emission limits was completed for EQUI17 and EQUI22

several times in the past. Results of performance testing are on file at the Minnesota Pollution Control

Agency (MPCA).

6.0 Electrostatic Precipitator

The Moorhead Sugar Beet Processing Plant uses electrostatic precipitators (ESP) to remove particulate

matter (PM and PM10) generated from the boilers at the facility.

ESPs use electrical energy to remove particulate matter from exhaust gas streams. As the exhaust

stream enters an ESP, particulate matter in the gas encounters negatively charged ions, which apply a

charge to the particles. The charged particles then are attracted to collector plates carrying the opposite

charge. As the particles accumulate, they periodically are removed from the collector plates and

collected in a hopper.

Metering generally includes a primary voltmeter, which measures the input voltage; primary ammeter,

which measures the current drawn across the transformer; secondary voltmeter, which measures the

voltage applied to the discharge electrodes; secondary ammeter, which measures the current supplied

to the discharge electrodes; and a sparkmeter, which measures the spark rate across the electrodes. To

maximize control efficiency, most ESPs are designed with several bus sections or fields, each of which is

equipped with separate, independent power supplies, controllers, and meters. Each of these fields acts

as a separate ESP. The power supplied to the initial fields generally is higher because particulate

concentrations are highest at the inlet. Having multiple fields allows the operator flexibility in operating

the ESP and reduces the likelihood of electrical failure shutting down the entire ESP.

Emission sources that utilize ESP control include the following:

5.2 Justification

The monitoring approach is consistent with the EPA CAM Technical Guidance Document, Section B.2,

ESPs, (1/05). As indicated in the guidance, the ESP controlled sources are considered small pollutant

specific emission sources (i.e., less than 100 tons per year post‐ controlled potential to emit); therefore,

CAM does not require continuous monitoring with four or more data points averaged over each hour.

The first indicator used to monitor ESP operation is number of fields online. As explained previously, the

ESPs are designed with multiple fields, each of which is operated independently of the others. If any of

the fields fail, the overall performance of the ESP will decrease; that reduction in performance will be a

function of which specific fields fail and which are still in operation. Section B.2 of the CAM guidance

indicates that the following are acceptable primary indicators of performance: outlet PM concentration,

opacity, secondary corona power, secondary current, secondary voltage, and fields in operation.

The second indicator used to monitor ESP operation is inspection and maintenance. ESP performance is

monitored by routine inspections of equipment performed by plant personnel. All excursions and

maintenance activities will be documented and reported in a maintenance log.



data makes compliance or performance testing unnecessary. The proposed indicator of the number of

fields online is based on manufacturer recommendations and historical plant operation data.

Furthermore the number of fields online were determined by performance testing, reviewed, approved

and listed as operational requirements in Air Emission Permit No. 02700001‐011 for the Moorhead

facility. Because the number of fields online were previously reviewed by regulatory staff and are listed


as a permit requirement, additional evaluation is not required. Performance testing demonstrating

compliance with applicable emission limits and setting the number of fields online was completed for

EQUI1, EQUI2 and EQUI16 several times in the past. Results of performance testing are on file at the

Minnesota Pollution Control Agency (MPCA).
