3. Facility description

Ardent Mills - Lake City Plant (Facility or Ardent Mills) operates a wheat flour mill and is located at 905 W Marion Street in Lake City, Wabasha County, Minnesota. The facility consists of grain receiving, elevators, grain cleaning, wheat mills, flour blending, storage, packaging, hammermilling, and a boiler. Ardent Mills processes wheat received into flour and middling (midds) for animal feed. Ardent Mills uses phosphine for fumigation. The main pollutants of concern are particulate matter (PM), particulate matter less than 10 micron (PM10), particulate matter less than 2.5 micron (PM2.5), and hazardous air pollutants (HAP). Ardent Mills uses fabric filter control equipment to reduce emissions of PM, PM10, and PM2.5.

Appendix B. Alternative Test Method for Opacity Determination of Emissions from Intermittent Dust-Generating Operations (alternative to Method 9).

1.1 Applicability: This method is applicable for the determination of opacity of fugitive dust plumes from intermittent dust-generating operations.


1.2 Principle: The opacity of emissions from sources of visible emissions is determined visually by a qualified observer certified according to the procedure in EPA Test Method 9.

1.3 Procedures: A qualified observer shall use the following procedures for visually determining the opacity of emissions. The Commissioner may approve changes to the alternative test method, in lieu of the test method described below, and based upon the criteria described in Minn. R. 7017.2050, subp. 2, items A and B.

1.3.1 To determine the opacity of non-continuous dust plumes caused by activities including, but not limited to, bulk material loading/unloading, bulk material handling, reclaim activities, and truck traffic within a bunker:

a. Position: The qualified observer must stand at least 25 feet, but no more than 200 feet from the dust-generating operation in order to provide a clear view of the emissions with the sun oriented in the 140º sector to their back. Choose a discrete portion of the operation for observation, such as the unloading point, not the whole operation. As much as possible following the above requirements, make opacity observations so that the line of vision is perpendicular to the dust plume and wind direction. If multiple plumes are involved, do not include more than one plume in the line of sight at one time.

b. Initial Fallout Zone: Opacity readings should be taken at the maximum point of the entrained fugitive dust plume that is located outside the initial fallout zone. The initial fallout zone is that area where the heaviest particles drop out of the entrained fugitive dust plume. The initial fallout zone within the plume must be identified. Record the distance from the equipment or path that is your identified initial fallout zone (provide a sketch to provide scale).

c. Field Records: Note the following on an observational record sheet:

(1) Location of dust-generating operation, type of operation, type of equipment in use and activity, and method of control used, if any;

(2) Observer's name, certification data and affiliation, a sketch of the observer's position relative to the dust-generating operation, and observer’s estimated distance and direction to the location of the dust-generating operation;

(3) Time that readings begin, approximate wind direction, estimated wind-speed, description of the sky condition (presence and color of clouds);

(4) Color of the plume and type of background; and

(5) Sketch of Initial Fallout Zone location relative to the emission source.

d. Observations: Make opacity observations, to the extent possible, using a contrasting background that is perpendicular to the line of vision. Make two observations per discrete activity, beginning with the first reading at zero seconds and the second reading at five seconds. The zero-second observation should begin immediately after a plume has been created above the surface involved. Do not look continuously at the plume but, instead, observe the plume briefly at zero seconds and then again at five seconds.

e. Recording Observations: Record the opacity observations to the nearest 5% on an observational record sheet. Each momentary observation recorded represents the average opacity of emissions for a five-second period. Repeat observations until you have recorded at least a total of 12 consecutive opacity readings. The 12 consecutive


readings must be taken within the same period of observation but must not exceed one hour. Observations immediately preceding and following interrupted observations can be considered consecutive (e.g., vehicle traveled in front of path, plume doubled over).

f. Data Reduction: Opacity is determined as the average of 12 consecutive opacity readings. Divide the observations into sets of 12 consecutive observations. In no case shall two sets overlap. For each set of 12 observations, calculate the average by summing the opacity of the 12 observations and dividing this sum by 12. If an applicable standard or requirement specifies a different averaging time, calculate the average for the observations in accordance with the specified time period. Record the average opacity on a record sheet. If the average opacity reading equals 20% or lower, the dust-generating operation is in compliance.

The existence of visible emissions only (not a specific opacity) is determined visually by an observer using EPA Test Method 22. The observer using EPA Test Method 22 is not required to be certified.

3. Technical information 3.1 Calculations of potential to emit (PTE)

Attachment 1 to this TSD contains detailed spreadsheets of emission calculations and supporting information prepared by the MPCA and the Permittee. Emissions from flour milling are calculated using AP-42 section 9.9.1 emission factors. Grain receiving, grain shipping, headhouse and internal handling, grain cleaning, bulk flour storage, and milling emission factors are applied to the total amount of grain processed by each operation at the facility. Therefore, to determine individual emissions from each unit, the emissions from each operation were divided by the number of units and design airflow of the control equipment the unit vents to. Other emissions at the facility include those from the boiler and fumigation. Boiler emissions are calculated using AP-42 section 1.4 and 1.3 emission factors. Ardent Mills uses insecticides to fumigate the facility, rail cars, and product. The current insecticides Ardent Mills uses contain phosphine or dichlorvos which are HAPs. The emissions from fumigation are calculated using manufacturer data.

3.2 Inherent Process Equipment

For purposes of determining potential to emit, "any physical or operational limitation on the capacity of the stationary source to emit a pollutant, including air pollution control equipment … must be treated as part of its design if the limitation or the effect it would have on emissions is federally enforceable”, Minn. R. 7005.0100, subp. 35a. There are situations based on case-by-case judgements where air pollution control equipment are an inherent part of the process and the effect of the equipment can be taken into accounts in calculating potential emissions. The flour milling fabric filters at Ardent Mills are considered control equipment because the fabric filters must be operated to avoid classification as a major source under 40 CFR 52.21 and 40 CFR pt. 70. The equipment that vent to the milling fabric filters and the milling fabric filters must meet hourly PM10 and PM2.5 Title I limits to avoid major source status under 40 CFR Section 52.21 and limits to avoid major source status under 40 CFR pt. 70.

3.3 Bulk Agricultural Commodity Facilities

Minn. R. 7011.1000 applies to dry bulk agricultural commodity facilities and defines such as “a facility where bulk commodities (grain, grain by-products, seed, beet pulp or pellets, and alfalfa meal or pellets) are unloaded, handled, cleaned, dried, stored, ground, or loaded…” For dry bulk agricultural commodity facilities that have an annual commodity throughput of more than 180,000 tons, control is required (Minn. R. 7011.1015) and applicable limits are provided in Minn. R. 7011.1005, subp. 3. The Ardent Mills facility unloads, handles, cleans, dries, stores, grinds, and loads bulk commodities and the facility has an annual commodity throughput more than 180,000 tons. Therefore, Ardent Mills is applicable to Minn. R. 7011.1000-1015.


3.4 Performance Testing Minn. R. 7017.2050, subp. 2(C) allows the commissioner to approve the use of an alternative test method if a performance test is not required for demonstration of compliance with a federal regulation. To address the intermittent nature of fugitive dust-generating operations, the MPCA developed Alternative Test Methods for Opacity Determination and Visible Emissions Observations. The Alternative Test Methods for Opacity Determination are required to be used for truck loading (COMG 2) and grain receiving (EQUI 1). Method 9 assumes that there is a continuous plume emitting from a stack, and that observations will be made at consistent intervals for a 1-hour period. This method does not work well for truck loading and truck and rail unloading, which are discontinuous operations in nature and do not have a defined stack. The MPCA relied upon rules developed for Maricopa County Arizona as a model for establishing Alternative Test Methods for Opacity Readings and Visible Emissions Observations. The MPCA established a maximum distance of 200 feet from the emission source as appropriate. The MPCA also incorporated the concept of using an initial fallout zone, to ensure that opacity readings are conducted at the maximum point of entrained fugitive dust. The initial fallout zone is the area where the heaviest particles drop out of the entrained fugitive dust plume. In general, observation points are a few feet downwind from the flow of material. The Permittee must make two observations per activity, beginning with the first reading at zero seconds and the second reading at five seconds. This method is repeated until a set of 12 consecutive readings are obtained within a one-hour period. The Alternative Test Methods for Opacity Determination and Visible Emissions Observations is included in Appendix B to the permit.

3.5 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.

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 5 summarizes the monitoring requirements. Table 5. Monitoring

What is the monitoring? Why is this monitoring adequate?




TFAC – Total Facility

Process Throughput <= 402,960 tons per year 12-month rolling sum of grain received [Title I Condition: Avoid major source under 40 CFR 52.21(b)(1)(i) and Minn. R. 7007.3000, To avoid major source under 40 CFR 70.2 & Minn. R. 7007.0200]

Daily and monthly recordkeeping and monthly calculation of the total quantity of grain received for the previous month and the 12-month rolling sum.

Grain records can be generated on a daily basis based on the tons of grain received at the flour mill. Daily records can be used to calculate the total amount of grain received for each month. The monthly totals can then be used to calculate the 12-month rolling sum. Therefore, a 12-month rolling limit is reasonable for this Facility. The grain receiving throughput limit effectively limits the grain handling, grain cleaning, wheat transfer and screening, and bulk loadout and packing for the entire facility. Ardent mills cannot process more grain than what is received.

COMG 1 – Flour Blending and Loading (EQUIs 287-294)

Opacity <= 10% opacity from truck loading stations fugitive emissions. [Minn. R. 7011.1005, subp. 3(B)]

None Emissions from flour blending and loading are captured one-hundred percent and controlled by fabric filters. Therefore, no fugitive emissions are expected.

COMG 2 – Feed Loadout (EQUIs 295-304)

Opacity <= 10% opacity from truck loading stations fugitive emissions. [Minn. R. 7011.1005, subp. 3(B)]

Performance testing

The Permittee is required to performance test for opacity using the Alternative Test Method for Opacity Determination of Emissions from Intermittent Dust-Generating Operations found in Appendix B of the permit. Performance testing is sufficient to have a reasonable assurance of compliance. 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. Based on current MPCA guidance, performance testing is required at a 60-month frequency.

EQUI 1 – Grain Receiving

Opacity <= 5% opacity from truck unloading stations fugitive emissions. [Minn. R. 7011.1005, subp. 3(A)]

Performance testing

The Permittee is required to performance test for opacity using the Alternative Test Method for Opacity Determination of Emissions from Intermittent Dust-Generating Operations found in Appendix B of the permit.

Past test results, applicable rules, potential emissions, location of source, and past compliance history play a factor in setting the testing frequency. Based on current MPCA guidance, performance testing is required at a 60-month frequency.




EQUIs 3, 4, 6-12, and 15-19 (various grain handling equipment)

Opacity <= 5% opacity from handling operation fugitive emissions. [Minn. R. 7011.1005, subp. 3(A)]

None Emissions from grain handling equipment and operations are captured one-hundred percent and controlled by fabric filters. Therefore, no fugitive emissions are expected.

EQUI 305 - Boiler Opacity <= 20% opacity [Minn. R. 7011.0515, subp. 2]

None The unit uses natural gas or propane therefore the likelihood of violating either one of the emission limits is very small. The Permittee can demonstrate that this unit will continue to operate such that emissions are well below the emission limits by burning natural gas only. Design based PTE for the unit, using AP-42, is 0.0077 lb/MMBtu compared to the PM rule limit of 0.4 lb/MMBtu.

PM <= 0.40 lbs/MMBtu heat input [Minn. R. 7011.0515, subp. 1]

FUGI 4 – Fugitive HAP Emissions

HAPs - Total <= 20.0 tons per year 12-month rolling sum to be calculated. [Title I Condition: Avoid major source under 40 CFR 63.2, To avoid major source under 40 CFR 70.2 & Minn. R. 7007.0200]

On-going records of material HAP contents; Monthly recordkeeping and calculations of emissions.

Ardent Mills hires a third party for fumigation, therefore HAP records generated on a monthly basis based on the HAP-containing materials purchased and used is reasonable. The monthly single and total HAP totals can then be used to calculate the 12-month rolling sum. Therefore, a 12-month rolling limit is reasonable for this Facility.

HAPs - Single <= 9.0 tons per year 12-month rolling sum [Title I Condition: Avoid major source under 40 CFR 63.2, To avoid major source under 40 CFR 70.2 & Minn. R. 7007.0200]

Performance testing

Ardent Mills provided filter control efficiency justifications in a response to the MPCA dated July 29, 2016. Information provided by the Buhler manufacturer suggests filter control efficiencies are for grain intake/handling and that filter loading is extremely important. Kice filter manufacturer states variations in efficiency can be expected when gas streams handling primarily very small particles occur. For fabric filters controlling milling process equipment at Ardent Mills, the flour and dust collected would be small particulates and thus the efficiency achieved by the fabric filters is not certain. Therefore, performance testing, in addition to operating limits for control equipment and associated monitoring, are sufficient to have a reasonable assurance of compliance. 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. Based on current MPCA guidance, performance testing is required at a 60-month frequency.

PM2.5 <= 1.41 pounds per hour 3-hour average [Title I Condition: Avoid major source under 40 CFR 52.21(b)(1)(i) and Minn. R. 7007.3000, To avoid major source under 40 CFR 70.2 & Minn. R. 7007.0200]

*Location of the requirement in the permit (e.g., EQUI 1, STRU 2, etc.).

3.6 Insignificant activities Ardent Mills LLC has operations that are classified as insignificant activities under the MPCA’s permitting rules. The operations are listed in Appendix A to the permit. 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. Table 6. Insignificant activities

Insignificant activity General applicable emission limit Discussion

Fugitive dust emissions from unpaved entrance roads and parking lots

Requirement to take reasonable measures to prevent PM from becoming airborne (Minn. R. 7011.0150)

The permit contains a general requirement that Minn. R. 7011.0150 must be met. The Facility has unpaved parking lots and unpaved entrance roads. All other private roads are paved.

3.7 Permit organization

One item that deviates from MPCA Tempo Guidance for ordering and grouping of requirements is the listing of certain applicable requirements at the total facility level even though they apply at the individual unit. Specifically: Minn. R. 7011.1005, subp. 1(A) of the Bulk Agricultural Commodity Facilities Rule is listed at TFAC. Minn. R. 7011.1005, subp. 1(A) requires Permittees to clean up commodities spilled on the driveway


and other facility property as required to minimize fugitive emissions to a level consistent with RACT. The MPCA does not need to track noncompliance with this requirement at the individual unit level so the permit team decided that listing the requirement under the facility level was an acceptable way to include this requirement.

3.8 Comments received

Public Notice Period: October 10, 2019 – November 12, 2019 EPA Review Period: October 10, 2019 – November 12, 2019 Comments were received from Ardent Mills during the public notice period. Changes were not made as a result of the comments received. Ardent Mills comments and MPCA responses are included in Attachment 4 to this TSD.

Comments were not received from EPA during their review period.

4. Permit fee assessment

This permit action is the issuance of an individual State permit based on an application received April 27, 2018. The application fees apply under Minn. R. 7002.0019. Attachment 3 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.

5. Conclusion Based on the information provided by Ardent Mills LLC the MPCA has reasonable assurance that the proposed operation of the emission facility, as described in the Air Emission Permit No. 15700034-101 and this TSD, will not cause or contribute to a violation of applicable federal regulations and Minnesota Rules.

TABLE NOTES:

1. The Part 1 Table are emission estimates for sources using AP‐42 emission factors from Section 9.9.1 (April 2003). The Part 2 Table are emission estimates for the mill using site specific stack test data. Sampling was performed on February 2, 2017on a grain receiving baghouse, a grain cleaning baghouse, and a grain milling baghouse.2. Grain is received by hopper truck or rail but for this analysis, it is assumed that all grain is received by hopper truck.3. It is conservatively assumed that for grain receiving, grain cleaning, and grain milling, PM‐2.5 emissions are equivalent to the observed PM‐10 emissions.4. The AP‐42 emission factors in Table Part 1 for the boiler are expressed in lbs. per million cu. ft. of natural gas, except PM/PM20/PM2.5 emission factors were revised by USEPA in 2014. The heating value for natural gas was assumed at 1,050 Btu/ft3. Boiler actual emissions based on 65% of PTE usage for heating season.5. The hammermill is only used when making animal feed and its annual use is estimated at 1%. To be conservative, we have assumed that it is in operation 100% of the time. The hammermill is controlled first by a cyclone and then by a fabric filter.6. Total PTE and actual emissions are calculated assuming a safety factor of 2.5

Pollutant/CAS Number

1 ‐ Ardent Mills currently hires a contractor to apply a variety of insecticides including Eco2Fume to fumigate product. Eco2Fume currently is the only insectide that contains 2.2% Phosphine, which is a HAP. Emissions of phosphine were considered to be equivalent to the usage of Eco2Fume and the maximum percentage of phosphine in the fumigant. The limit was set at greater than 95% of the threshold (limit is 9.0 tons per year, single HAP and 20.0 tons per year total HAP) – as there is no uncertainty associated with an emission factor. PTE calculations are based on actual emissions multplied by a conservative safety factor of 100. The fumigation process emissions have historically been below 1 ton per year.

Attachment 4 - Public Notice Comments and Responses

Ardent Mills: This Public Comment submittal has been prepared as a follow up to our meeting at the

Minnesota Pollution Control Agency (MPCA) offices on October 23, 2019. As discussed during the

meeting, Ardent Mills wishes to propose that a controlled emission factor of 0.01 grains of Particulate

Matter (PM)/dry standard cubic feet (gr/dscf) be used to calculate emissions from the Milling Stacks:

STRUs 6,7, 8, 9. 10, 11, 12, and 13. These stacks represent pneumatic and purifier stacks at Mills A, B and

C. It is assumed that controlled PM10 emissions are 80% of PM emissions, and that the controlled PM2.5

emission rate is equal to the controlled PM10 emission rate (0.008 gr/dscf).

Ardent Mills proposes that this methodology be used in lieu of the Wheat Milling emission factor of 70

lb/ton listed in AP-42 Table 9.9.1-2 (3/03). The AP-42 emission factor is based on an EPA study

conducted in 1973 and has an “E” rating. EPA has indicating that an E rating indicates that the factor is

poor, is developed on test data from a very few number of facilities, and that these facilities do not

1. Based on the new proposed emission factor, Ardent Mills requests that the hourly emission limits

listed in the draft air emissions permit 15700034-101 for STRUs 6, 7, 8, 9, 10, 11, 12, and 13 be removed

and replaced with the assumed controlled emission factors of 0.01 gr/dscf for PM and 0.008 gr/dscf for

PM10 and PM2.5.

2. In addition, Ardent Mills requests that the stack testing requirements listed in Section 6 of the permit

for STRUs 6, 7, 8, 9, 10, 11, 12, and 13 be removed. Ardent Mills suggests that if stack testing is required

to verify the proposed emission factors, that a single representative stack be tested to represent the

pneumatic sources (STRU/TREAs 6, 7, 11, and 13), and a single representative stack test be conducted

for the purifier stacks (STRU/TREAs 8, 9, 10, and 12).

3. A stack testing frequency of every 10 years is proposed based on Minn. R. 7019.3050 as stack testing

would be used to verify an emission factor.

Background Information Supporting Ardent Mills Request:

The pneumatic stacks represent exhaust points from the pneumatic conveyance fl our . The purifier

stacks represent exhaust emission points where flour is being sifted. The pneumatic stacks are preceded

by a process cyclone for material recovery prior to the fabric filter, (STRU/TREAs 6, 7, 11, and 13). The

purifier emissions typically vent directly to a fabric filter (STRU/TREAs 8, 9, 10, and 12). The pneumatic

sources are similar sources and are expected to result in a similar concentration-based emission rate.

The same applies for the purifier sources, which are similar processes and are expected to result in a

similar concentration-based emission rate for those sources.

Both pneumatic and purifier emission sources are controlled by the same fabric filter socks and are

expected to have a similar exhaust particulate concentration. Each of TREAs uses the same Donaldson

Dura-Life bag filters, which have been tested to show an exhaust emission rate of 0.0028 gr/dscf based

on Donaldson's emission testing (see attached documentation from Donaldson).

On February 2, 2017, Ardent Mills conducted stack testing on three stacks: one grain receiving stack,

grain cleaning stack, and C Milling Pneumatic stack (STRU/TREA 13). The testing was conducted by Pace

Analytical and EPA Test Methods 1-4, 201A and 202 were performed.

Emission rates for PM and PM10 were reported. During the testing period, the C mill processed 12.3

tons of flour per hour, which is approximately 90% of the C mill capacity (14.3 tons per hour). The test

resulted in emission rates of 0.0026 gr/dscf for PM and 0.0021 gr/dscf for PM10. The stack test indicated

that the PM10 emission rate is approximately 80% of the PM emission rate.

Both the documentation from Donaldson, and the stack testing conducted at the facility suggest that the

proposed controlled emission factors can be met and will effectively restrict facility emissions to less

than major source thresholds with respect to 40 CFR Part 70 and 40 CFR Part 52.21.

MPCA: A summary of your comments followed by MPCA responses is provided in this email below. Note

that Ardent Mills will need to reply to the MPCA in regards to comment #1 by December 5th.

1. Ardent Mills: Based on the new proposed emission factor, Ardent Mills requests that the hourly

emission limits listed in the draft air emissions permit 15700034-101 for STRUs 6, 7, 8, 9, 10, 11,

12, and 13 be removed and replaced with the assumed controlled emission factors of 0.01

gr/dscf for PM and 0.008 gr/dscf for PM10 and PM2.5.

MPCA: The MPCA can remove the PM10 and PM2.5 lb/hr limits for STRUs 6, 7, 8, 9, 10, 11, 12, and 13

listed in Draft permit 15700034-101, however the proposed emission factors of 0.01 gr/dscf for PM and

0.008 gr/dscf for PM10 and PM2.5 would be listed as limits. In addition, the airflow capacities for each

STRU would need to be listed as limits. A grain loading limit is not enough to limit emissions.

Ardent Mills would need to operate the fabric filters that vent to STRUs 6, 7, 8, 9, 10, 11, 12, and 13 so

that the airflow rates are less than or equal to the limits in the permit. Monitoring requirements for this

would be included in the permit.

Ardent Mills should reply to the MPCA by December 5, 2019 to confirm whether they would like to

proceed with changing the PM10 and PM2.5 hourly limits to concentration limits and adding air flow

limits, or would like to accept the hourly emission rates initially proposed.

2. Ardent Mills: In addition, Ardent Mills requests that the stack testing requirements listed in

Section 6 of the permit for STRUs 6, 7, 8, 9, 10, 11, 12, and 13 be removed. Ardent Mills suggests

that if stack testing is required to verify the proposed emission factors, that a single

representative stack be tested to represent the pneumatic sources (STRU/TREAs 6, 7, 11, and

13), and a single representative stack test be conducted for the purifier stacks (STRU/TREAs 8, 9,

10, and 12).

MPCA: The MPCA is requiring performance testing for STRUs 6 through 13 to demonstrate that the

facility PM10 and PM2.5 emissions are below major source thresholds for 40 CFR 52.21 and Part 70.

Although Ardent Mills has two types of process stacks, pneumatic and purifier, the airflow rates, number

of units, and type of units vary for each stack. In order to demonstrate that all combined emissions from

the Lake City facility are below PM10 and PM2.5 major source thresholds for 40 CFR 52.21 and Part 70,

performance tests will be required for each stack.

3. Ardent Mills: A stack testing frequency of every 10 years is proposed based on Minn. R.

7019.3050 as stack testing would be used to verify an emission factor.

MPCA: Performance testing frequency is determined on a case-by-case basis considering applicable

rules, potential emissions, past compliance history, etc. Because Ardent Mills is required to demonstrate

compliance with PM10 and PM2.5 major source thresholds for 40 CFR 52.21 and Part 70, Ardent Mills is

required to test at a 60 month frequency, or more frequently based on testing results and MPCA review.

As stated in the permit, if the MPCA sets a test frequency less than every 60 months, Ardent Mills must

apply for an administrative amendment to incorporate the prescribed test frequency into the permit.

Once Ardent Mills establishes a compliance history for STRUs 6, 7, 8, 9, 10, 11, 12, and 13, Ardent Mills

can request the performance testing frequency to be reduced.

Ardent Mills: To include permit limits on both gr/dscf concentration and on air flow actually more

restrictive than what MPCA listed in the draft permit on public notice. If actual air flow rates were

higher, but particulate concentration were lower than the proposed gr/dscf limits, it’s possible that the

facility could still be limited to less than major source thresholds with respect to Title V and PSD. In our

meeting, the MPCA did not state that a gr/dscf emission limit would not be acceptable. In response to

this comment, Ardent Mills has converted the proposed gr/dscf emission factors to a lb of

particulate/ton of wheat processed by the mill emission factor for each stack. We’ve applied the highest

resulting emission factor for the stacks to all of the 8 stacks. The resulting emission factors are 0.084 lb

PM per ton of grain processed and 0.067 lb of PM10 or PM2.5 per ton of grain processed. Using these

emission factors, and the existing throughput limit of 402,960 tons of grain processed annually,

particulate emissions are restricted to well below Title V thresholds. Please see the attached

spreadsheet. (Spreadsheet available in the MPCA Tempo database.)

Emissions factors aren’t intended to represent actual emissions from each stack. The intent is to

establish an emission factor that can be met by all stacks. 0.01 gr/dscf for PM and 0.008 gr/dscf for

PM10/PM2.5 is a very conservative assumption given what the stack test data we’ve already provided

has indicated, and also given how well fabric filter performance is understood. Given that the stack test

data on the pneumatic stacks was at 0.003 gr/dscf for PM and 0.0026 gr/dscf for PM10 and we’re

proposing to base emission factors based on 0.01 gr/dscf and 0.008 gr/dscf, there should be enough

margin within that delta account for any variability among stacks. Additionally, there are a lot of

emission factors for the pneumatic conveyance of material within AP-42 that can be used, such as the

emission factor for the pneumatic conveyance of Portland Cement at cement plants. This factor is

widely used in industrial bakeries for the pneumatic conveyance of material around those facilities.

Ardent Mills believes that a conservative emission factor has been proposed and that we have

substantiated the validity of the emission factor with enough data, that the MPCA should have enough

confidence to not require such a rigorous performance testing schedule. If MPCA feels that all stacks

need to be testing, then establishing a rotating schedule whereby a different stack is tested every 5

years seems more appropriate. Is the level of testing required in Ardent Mills’ Lake City draft permit

consistent with stack testing frequency required for other wheat flour mills in Minnesota owned by

other companies?

Ardent Mills’ goal was to establish an emission factor and test to demonstrate compliance with an

emission factor. Ardent Mills has provided stack test data to validate the proposed emission factor.

What additional information is needed to develop an emission factor and substantiate less frequent

performance testing? If an administrative amendment to request less frequent stack testing were to be

submitted to MPCA, they wouldn’t be able to move forward with the change until the amendment had

been incorporated into the permit. How long would it take MPCA to incorporate an administrative

amendment application upon receipt of a complete application?

MPCA: Thank you for your comments you provided on December 5, 2019. The MPCA considered

performance testing for emission limits and emission factors. Regardless of whether performance

testing is required for an emission factor or emission limit, testing must be conducted at worst case

operating conditions (Minn. R. 7017.2025) therefore operating conditions and the emission rate must be

verified. Emission factors are determined based on the emission rate results and the emission unit(s)

operating conditions under which the tests were conducted. Both emission factor and emission limit

MPCA verified testing results can be used to calculate actual emissions (Minn. R. 7019.3050).

Additionally, whether performance tests are for emission limits or emission factors, there is no

difference when establishing test frequency. Test frequency is determined on a case-by-case basis

considering the purpose of the test, applicable rules, potential emissions, past compliance history, etc.

Ardent Mills may not test at a frequency of once every 10 years because Ardent Mills is not simply

verifying an emission factor for the purposes of emission inventory. Ardent Mills must demonstrate

compliance with limits to avoid PM10 and PM2.5 major source thresholds for PSD and Part 70 in order

to maintain eligibility for a state permit. The MPCA is still requiring Ardent Mills to test at a 60 month

frequency, or possibly more frequently based on testing results and MPCA review.

The performance testing requirements in the draft permit are based on MPCA verified standard

language and are consistent with other current permitted facilities including milling and grain handling

facilities. Only if the MPCA sets a test frequency less than every 60 months based on test results, i.e. 24

or 36 months, Ardent Mills must apply for an administrative amendment to incorporate the prescribed

test frequency into the permit. Ardent Mills would need to submit a major amendment to reduce

performance testing frequency. A 60-month performance testing frequency is considered a minimum

testing frequency.

Although the emission factors Ardent Mills proposed are more restrictive than the hourly limits provided

in the draft permit, the MPCA determined there is no compelling reason to justify a less restrictive test

frequency.

The MPCA did edit the performance testing requirements to correct the due date based on permit

issuance and not initial startup. Initial startup was included erroneously. This change is considered an

administrative change and therefore the MPCA will proceed with permit issuance.
