There are two truck dump pits located at the facility which are connected to a single receiving line. Soybeans are the 

only grain received. Typically soybeans are received Monday through Friday, 6am to 5pm. During harvest season, 

soybeans may also be received on the weekends or for extended hours during the week. The truck dumps are fitted 

with aspiration lines to collect dust and route it to a baghouse. There are currently two baghouses, one for each dump 

pit. A choke flow system is also used. It takes approximately 5 minutes to dump one truck, not including time for the 

driver to get on spot.

 N/A N/A N/A The facility is permitted to utilize one rail dump pit located at the south side of the facility. Soybeans are the only grain 

received. This system is not utilized on a continuous or routine basis. Soybeans are typically received by rail during 

harvest season, but may be received by rail at other times during the year based on the market. The rail dump is fitted 

with aspiration lines to collect dust and route it to a baghouse. A choke flow system is also used and louvered grates are 

installed. It takes approximately 15 minutes to dump one railcar, including time to get the car on spot.

 N/A The facility is permitted to utilize one grain dryer located at the south side of the elevator. The dryer is permitted to 

combust either natural gas or No. 2 Fuel Oil as fuel. Soybeans are the only grain dried. This system has not been 

operated since 2005. The dryer has been re-screened such that it is in compliance with the existing NSPS, Subpart DD 

regulations. 

This facility processes soybeans in order to extract the oil from the beans. There are multiple bucket elevators, legs, and 

scalpers. There is also a headhouse. Much of this equipment is operated at all times the production facility is operating. 

All of the elevators and legs are enclosed and many are aspirated to baghouses for emission control.

Archer Daniels Midland Company – Des Moines Soybean Processing Grain 

Elevator Diagram (10/2009)

Soybeans are received by truck at one of two truck dump pits (TD-1 & TD-2). Each truck dump pit is 

currently controlled by its own fabric filter/baghouse (APCD-1 & APCD-2). The two truck dump pits are 

connected to a single receiving conveying system (R-1) that take the soybeans from the dump pits to 

West Side storage (P-1). Beans are then transported from West Side Storage by receiving conveying 

system R-3 to concrete storage (P-3). The conveying system is controlled by a fabric filter/baghouse 

(APCD-4). Beans are transported to the process from concrete storage (P-3).

Soybeans are received by rail at one rail dump pit (RD-1) located on the south side of the processing 

plant. The rail dump pit is controlled by a fabric filter/baghouse (APCD-3). Receiving soybeans by rail 

does not occur as must as truck, therefore this system is used sporadically. Beans received by rail are 

transferred to South storage (P-2) by receiving conveying system R-2. From South storage, the beans 

are transported to the process.

The facility currently has one operational dryer located on site. It is a column dryer and is permitted to 

combust natural gas and No. 2 Fuel oil. The dryer is able to take “wet” beans from one of the concrete 

silos and put dry beans into another silo.

I. Facility Description and Equipment List 

Facility Name: Archer Daniels Midland - Des Moines Soybean Plant 

Permit Number: 04-TV-020-M001 

Facility Description: This facility produces soybean meal and refined vegetable oil. The 

Des Moines plant also maintains a coal fired cogeneration facility for the generation of 

process steam and electricity. 

Soybeans are received at the Des Moines facility by either truck or railcar. The beans are 

then cleaned and conveyed to storage. When the beans have high moisture content, such 

as during harvest time, they may be dried in one of three grain dryers located onsite. 

Processing of the soybeans includes drying, cracking, de-hulling and flaking prior to 

vegetable oil extraction. Hulls removed from the bean are ground and possibly pelletized 

to aid in hull transfer/load-out. The defatted flakes from the extraction process are sent 

through a series of processes that de-solventize, dry and grind the resulting meal. The 

meal and hulls/pellets are transferred to storage until loaded out either by rail or truck. 

The vegetable oil extracted from the soybeans is separated from the solvent used in the 

extraction process and then sent to the onsite vegetable oil refinery for further processing. 

The refining process removes impurities and residual solvent in the oil.

Authority for Requirement: 567 IAC 22.108(14) 

Compliance Plan

The owner/operator shall comply with the applicable requirements listed below. The 

compliance status is based on information provided by the applicant. 

Archer Daniels Midland (ADM) has entered into a Consent Decree with the United States 

EPA and 14 state and local air programs (Including the State of Iowa and Polk County 

Air Quality Division) in order to resolve a number of alleged violations at its 43 facilities 

located in 16 states. Included in this Consent Decree is the Soybean processing plant in 

Des Moines, Iowa. 

A copy of the Consent Decree is available on the internet at the following address: 

www.epa.gov/compliance/resources/decrees/index.html

The Authority for this is: Consent Decree C.D. IL, #03-CV-2066 

 567 IAC 22.108(1) 
 ADM – Des Moines Soybean Plant 

 10 04-TV-020-M001 

 December 7, 2006 

ADM shall meet all requirements of the Consent Decree. Included among those 

requirements that are applicable to the Des Moines facility are: 

1) By no later than December 31, 2007, ADM shall propose in writing to the 

Plaintiffs final VOC SLR limits for each oilseed plant ...that satisfy the 

requirements of Paragraphs 67 through 69 ( of the Consent Decree)... 

2) For a plant that has an existing permit limit lower than the applicable solvent 

loss factor (SLF) in 40 CFR part 63 Subpart GGGG (vegetable oil production 

NESHAP), ADM may not propose a final SLR limit that is greater than the 

existing limit.... 

3) The first compliance determination will be based on the first 12 operating 

months of data collected after the date on which each VOC SLR limit is 

proposed. 

4) The capacity weighted average of the Final SLR limit for the conventional 

soybean plants shall not exceed 0.175 gal/ton. 

5) The capacity weighted averages shall be based on the design capacity for each 

facility. Within 90 days of the lodging of the Consent Decree, ADM shall 

submit, for approval by EPA and the appropriate Plaintiffs, the design 

capacity values for this facility. For the purposes of the Consent Decree, 

design capacity is the “maximum permitted crush capacity” that a plant is 

allowed to process in a given time period under its operating permit, or, if not 

limit is included in the operating permit, the facility’s maximum physical 

capacity. This number shall be expressed as “tons of crush per day.” 

6) Solvent Loss Limits. Compliance with the interim and final VOC SLR limits 

in the Consent Decree shall be determined in accordance with 40 CFR Part 63, 

Subpart GGGG, with the following exceptions: 1) provisions pertaining to 

HAP content shall not apply; 2) monitoring and recordkeeping of solvent 

losses at each plant shall be conducted daily; 3) solvent losses and quantities 

of oilseed processed during startup and shutdown periods shall be kept in the 

form of the table in Attachment 13, that show total solvent losses, solvent 

losses during malfunction periods, and adjusted solvent losses (i.e., total 

solvent losses minus malfunction losses) monthly and on a twelve month 

rolling basis. 

7) Malfunctions. ADM may apply the provisions of 40 CFR Part 63 Subpart 

GGGG pertaining to malfunction periods only when both of the following 

conditions are met: 1) The malfunction results in a total plant shutdown. For 

the purposes of the decree, a “total plant shutdown “ means a shutdown of the 

solvent extraction system and 2) Cumulative solvent losses during 

malfunction periods at the plant do not exceed 4,000 gallons in a 12-month 

rolling period. At all other times, ADM must include all solvent losses when 

determining compliance with its interim or final VOC SLR limits at the plant. 

During a malfunction period, ADM shall comply with the Start up, Shutdown, 

Malfunction (“SSM”) Plan as required under Subpart GGGG for the plant. 

The solvent loss will be calculated as the difference in the total solvent 

inventories for the day before the malfunction period began and the day the 

plant resumes normal operation.

 December 7, 2006 

8) General Permitting Requirements. ADM shall seek to obtain all appropriate 

construction permits or permit waivers for emission reduction projects 

undertaken to comply with interim or final VOC SLR limits, as determined in 

accordance with the rules and practice of the appropriate permitting authority. 

9) NAAQS Modeling in Iowa. ADM shall submit NAAQS modeling to Iowa 

DNR for the Des Moines Soybean Processing Plant(SO2, NOx and PM10) 

within five years from the date of lodging. 

10) Environmental Audits. ADM shall conduct a comprehensive review of the 

compliance status of this plant a minimum of twice during the life of the 

Decree. These audits shall be conducted as required by the Decree. 

Unless otherwise noted in Section III of this permit, Archer Daniels Midland Des Moines 

Soybean Plant is in compliance with all applicable requirements and shall continue to 

comply with all such requirements. For those applicable requirements which become 

effective during the permit term, Archer Daniels Midland Des Moines Soybean Plant 

shall comply with such requirements in a timely manner.

Periodic Monitoring Requirements 

The owner/operator of this equipment shall comply with the periodic monitoring 

requirements listed below. 

EP U06 shall be visually checked for observable emissions once every week by a 

designated observer. The observation shall be taken while the equipment is operating at 

or near full capacity. The observation shall be noted in a log book, which shall state the 

date, time, observer’s signature, and whether any emissions were observed. If visible 

emissions are observed, corrective action will be taken as soon as possible, but no later 

than eight hours from the observation of visible emissions. If corrective action does not 

return the observation to no visible emissions, then a Method 9 observation will be 

required. If an opacity >20% is observed, this would be a violation and corrective action 

will be taken as soon as possible, but no later than eight hours from the observation of 

visible emissions. If weather conditions prevent the observer from conducting an opacity 

observation, the observer shall note such conditions on the data observation sheet. At 

least three attempts shall be made to retake opacity readings at approximately 2-hour 

intervals throughout the day. If all observation attempts for a week have been 

unsuccessful due to weather, an observation shall be made the next operating day where 

weather permits. The log book will be maintained on site for 5 years and be made 

available to representatives of Polk County AQD upon request.

Periodic Monitoring Requirements 

The owner/operator of this equipment shall comply with the periodic monitoring 

requirements listed below. 

EP GP05a shall be visually checked for observable emissions once every week by a 

designated observer. The observation shall be taken while the equipment is operating at 

or near full capacity. The observation shall be noted in a log book, which shall state the 

date, time, observer’s signature, and whether any emissions were observed. If visible 

emissions are observed, corrective action will be taken as soon as possible, but no later 

than eight hours from the observation of visible emissions. If corrective action does not 

return the observation to no visible emissions, then a Method 9 observation will be 

required. If an opacity > 0% is observed, this would be a violation and corrective action 

will be taken as soon as possible, but no later than eight hours from the observation of 

visible emissions. If weather conditions prevent the observer from conducting an opacity 

observation, the observer shall note such conditions on the data observation sheet. At 

least three attempts shall be made to retake opacity readings at approximately 2-hour 

intervals throughout the day. If all observation attempts for a week have been 

unsuccessful due to weather, an observation shall be made the next operating day where 

weather permits. The log book will be maintained on site for 5 years and be made 

available to representatives of Polk County AQD upon request. 

Stack Testing: 

An Iowa Method 5 stack test was successfully conducted on the system on April 29, 2003 in 

accordance with Construction Permit 1407 requirements. The test demonstrated compliance

Operational Limits & Requirements

The owner/operator of this equipment shall comply with the operational limits and 

requirements listed below. 

This unit is subject to 40 CFR Part 63 Subpart GGGG - National Emission Standards for 

Solvent Extraction for Vegetable Oil Production and Subpart A – General Provisions. 

Below is a summary of those requirements. 

• Note: For consistency purposes, citations are consistent with the CFR. 

§63.2833 Is my source categorized as existing or new?

(a) This subpart applies to each existing and new affected source. You must categorize 

your vegetable oil production process as either an existing or a new source. 

• This source was constructed before May 26, 2000 therefore it is considered an 

existing source. 

§63.2834 When do I have to comply with the standards in this subpart?

(a) This source is considered an existing source, therefore it must be in compliance with 

this subpart within 3 years after the effective date (effective date = April 12, 2001). 

STANDARDS 

§63.2840 What emission requirements must I meet?

(a)(1) The emission requirements limit the number of gallons of HAP lost per ton of 

listed oilseeds processed. For each operating month, you must calculate a compliance 

ratio which compares your actual HAP loss to your allowable HAP loss for the previous 

12 operating months as shown in Equation 1 of this section. An operating month, as 

defined in §63.2872, is any calendar month in which a source processes a listed oilseed, 

excluding any entire calendar month in which the source operated under an initial startup 

period subject to §63.2850(c)(2) or (d)(2) or a malfunction period subject to 

§63.2850(e)(2). Equation 1 of this section follows: 

Allowable HAP Loss

Actual HAP Loss Compliance Ratio = Equation 1 

(2) Equation 1 of this section can also be expressed as a function of total solvent loss as

shown in 

Equation 2 of this section. Equation 2 of this section follows: 

0.64 * ( ) ( ) Oilseed *(SLF)

f *ActualSolvent Loss ComplianceRatio =

Where: 

f = The weighted average volume fraction of HAP in solvent received during the previous 

12 operating months, as determined in §63.2854, dimensionless. 

0.64 = The average volume fraction of HAP in solvent in the baseline performance data, 

dimensionless. 

Actual Solvent Loss = Gallons of actual solvent loss during previous 12 operating 

months, as determined in §63.2853. 

 Oilseed = Tons of each oilseed type “i” processed during the previous 12 operating 

months, as shown in §63.2855. 

SLF = The corresponding solvent loss factor (gal/ton) for oilseed “i” listed in Table 1 of

(b) When your source has processed listed oilseed for 12 operating months, calculate the 

compliance ratio by the end of each calendar month following an operating month using 

Equation 2 of this section. When calculating your compliance ratio, consider the 

conditions and exclusions in paragraphs (b)(1) through (6) of this section: 

(1) If your source processes any quantity of listed oilseeds in a calendar month 

and the 

source is not operating under an initial startup period or malfunction period 

subject to §63.2850, then you must categorize the month as an operating month, 

as defined in §63.2872. 

(2) The 12-month compliance ratio may include operating months occurring prior 

to a source shutdown and operating months that follow after the source resumes 

operation. 

(3) If your source shuts down and processes no listed oilseed for an entire 

calendar month, then you must categorize the month as a nonoperating month, as 

defined in §63.2872. Exclude any nonoperating months from the compliance 

ratio determination. 

(4) If your source is subject to an initial startup period as defined in §63.2872, 

exclude from the compliance ratio determination any solvent and oilseed 

information recorded for the initial startup period. 

(5) If your source is subject to a malfunction period as defined in §63.2872, 

exclude from the compliance ratio determination any solvent and oilseed 

information recorded for the malfunction period. 

(6) For sources processing cottonseed or specialty soybean, the solvent loss factor 

you use to determine the compliance ratio may change each operating month 

depending on the tons of oilseed processed during all normal operating periods in 

a 12 operating month period. 

(c) If the compliance ratio is less than or equal to 1.00, your source was in compliance 

with the 

HAP emission requirements for the previous operating month. 

(d) To determine the compliance ratio in Equation 2 of this section, you must select the 

appropriate oilseed solvent loss factor from Table 1 of this section. 

COMPLIANCE REQUIREMENTS 

§63.2850 How do I comply with the hazardous air pollutant emission standards?

(a) General requirements. The requirements in paragraphs (a)(1)(i) through (iv) of this 

section apply to all affected sources: 

(1) Submit the necessary notifications in accordance with §63.2860, which 

include: 

(i) Initial notifications for existing sources. 

(ii) Initial notifications for new and reconstructed sources. 

(iii) Initial notifications for significant modifications to existing or new 

sources. 

(iv) Notification of compliance status. 

(2) Develop and implement a plan for demonstrating compliance in accordance 

with §63.2851. 
 ADM – Des Moines Soybean Plant 

 55 04-TV-020-M001 

 December 7, 2006 

(3) Develop a written startup, shutdown and malfunction (SSM) plan in 

accordance with the provisions in §63.2852. 

(4) Maintain all the necessary records you have used to demonstrate compliance 

with this subpart in accordance with §63.2862. 

(5) Submit the reports in paragraphs (a)(5)(i) through (iii) of this section: 

(i) Annual compliance certifications in accordance with §63.2861(a). 

(ii) Periodic SSM reports in accordance with §63.2861(c). 

(iii) Immediate SSM reports in accordance with §63.2861(d). 

(6) Submit all notifications and reports and maintain all records required by the 

General Provisions for performance testing if you add a control device that 

destroys solvent. 

(b) Existing sources under normal operation. You must meet all of the requirements 

listed in paragraph (a) of this section and Table 1 of this section (see Appendix B of 

this permit) for sources under normal operation, and the schedules for demonstrating 

compliance for existing sources under normal operation in Table 2 of this section (see 

Appendix B of this permit). 

§63.2851 What is a plan for demonstrating compliance? 

(a) You must develop and implement a written plan for demonstrating compliance that 

provides the detailed procedures you will follow to monitor and record data necessary 

for demonstrating compliance with this subpart. Procedures followed for quantifying 

solvent loss from the source and amount of oilseed processed vary from source to 

source because of site-specific factors such as equipment design characteristics and 

operating conditions. Typical procedures include one or more accurate measurement 

methods such as weigh scales, volumetric displacement, and material mass balances. 

Because the industry does not have a uniform set of procedures, you must develop 

and implement your own site-specific plan for demonstrating compliance before the 

compliance date for your source. You must also incorporate the plan for 

demonstrating compliance by reference in the source’s title V permit and keep the 

plan on-site and readily available as long as the source is operational. If you make 

any changes to the plan for demonstrating compliance, then you must keep all 

previous versions of the plan and make them readily available for inspection for at 

least 5 years after each revision. The plan for demonstrating compliance must include 

the items in paragraphs (a)(1) through (7) of this section: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production process. 

(3) A detailed description of all methods of measurement your source will use to 

determine your solvent losses, HAP content of solvent, and the tons of each type 

of oilseed processed. 

(4) When each measurement will be made. 

(5) Examples of each calculation you will use to determine your compliance 

status. Include examples of how you will convert data measured with one 

parameter to other terms for use in compliance determination. 

(6) Example logs of how data will be recorded. 

(7) A plan to ensure that the data continue to meet compliance demonstration 

needs. 
 ADM – Des Moines Soybean Plant 

 56 04-TV-020-M001 

 December 7, 2006 

(b) The responsible agency of these NESHAP may require you to revise your plan for 

demonstrating compliance. The responsible agency may require reasonable revisions if 

the procedures lack detail, are inconsistent or do not accurately determine solvent loss, 

HAP content of the solvent, or the tons of oilseed processed. 

§63.2852 What is a startup, shutdown, and malfunction plan?

You must develop a written SSM plan in accordance with §63.6(e)(3) and implement the 

plan, when applicable. You must complete the SSM plan before the compliance date for 

your source. You must also incorporate the SSM plan by reference in your source’s 

title V permit and keep the SSM plan on-site and readily available as long as the source is 

operational. The SSM plan provides detailed procedures for operating and maintaining 

your source to minimize emissions during a qualifying SSM event for which the source 

chooses the §63.2850(e)(2) malfunction period, or the §63.2850(c)(2) or (d)(2) initial 

startup period. The SSM plan must specify a program of corrective action for 

malfunctioning process and air pollution control equipment and reflect the best practices 

now in use by the industry to minimize emissions. Some or all of the procedures may 

come from plans you developed for other purposes such as a Standard Operating 

Procedure manual or an Occupational Safety and Health Administration Process Safety 

Management plan. To qualify as a SSM plan, other such plans must meet all the 

applicable requirements of these NESHAP. 

§63.2853 How do I determine the actual solvent loss?

By the end of each calendar month following an operating month, you must determine 

the total solvent loss in gallons for the previous operating month. The total solvent loss 

for an operating month includes all solvent losses that occur during normal operating 

periods within the operating month. If you have determined solvent losses for 12 or more 

operating months, then you must also determine the 12 operating months rolling sum of 

actual solvent loss in gallons by summing the monthly actual solvent loss for the previous 

12 operating months. The 12 operating months rolling sum of solvent loss is the “actual 

solvent loss,” which is used to calculate your compliance ratio as described in §63.2840.

(a) To determine the actual solvent loss from your source, follow the procedures in your 

plan for demonstrating compliance to determine the items in paragraphs (a)(1) 

through (7) of this section: 

(1) The dates that define each operating status period during a calendar month. 

The dates that define each operating status period include the beginning date 

of each calendar month and the date of any change in the source operating 

status. If the source maintains the same operating status during an entire 

calendar month, these dates are the beginning and ending dates of the calendar 

month. If, prior to the effective date of this rule, your source determines the 

solvent loss on an accounting month, as defined in §63.2872, rather than a 

calendar month basis, and you have 12 complete accounting months of 

approximately equal duration in a calendar year, you may substitute the 

accounting month time interval for the calendar month time interval. If you 

choose to use an accounting month rather than a calendar month, you must 

document this measurement frequency selection in your plan for 

demonstrating compliance, and you must remain on this schedule unless you 

request and receive written approval from the agency responsible for these 

NESHAP. 

(2) Source operating status. You must categorize the operating status of your 

source for each recorded time interval in accordance with criteria in Table 1 of 

this section, as follows: 

Table 1 of §63.2853 – Categorizing Your Source Operating Status 

If during a recorded time interval... then your source operating status 

is... 

(i) your source processes any amount of listed 

oilseed and your source is not operating under an 

initial startup period or a malfunction period 

subject to §63.2850(c)(2), (d)(2), or (e)(2) 

a normal operating period. 

(ii) your source processes no agricultural product 

and your source is not operating under an initial 

startup period or malfunction period subject to 

§63.2850(c)(2), (d)(2), or (e)(2) 

a nonoperating period. 

(iii) you choose to operate your source under an 

initial startup period subject to §63.2850(c)(2) or 

(d)(2) 

an initial startup period. 

(iv) you choose to operate your source under a 

malfunction period subject to §63.2850(e)(2) 

a malfunction period. 

(v) your source processes agricultural products 

not defined as listed oilseed 

an exempt period. 
(3) Measuring the beginning and ending solvent inventory. You are required to 

measure and record the solvent inventory on the beginning and ending dates of 

each normal operating period that occurs during an operating month. An 

operating month is any calendar month with at least one normal operating period. 

You must consistently follow the procedures described in your plan for 

demonstrating compliance, as specified in §63.2851, to determine the extraction 

solvent inventory, and maintain readily available records of the actual solvent loss 

inventory, as described in §63.2862(c)(1). In general, you must measure and 

record the solvent inventory only when the source is actively processing any type 

of agricultural product. When the source is not active, some or all of the solvent 

working capacity is transferred to solvent storage tanks which can artificially 

inflate the solvent inventory. 

(4) Gallons of extraction solvent received. Record the total gallons of extraction 

solvent received in each shipment. For most processes, the gallons of solvent 

received represents purchases of delivered solvent added to the solvent storage 

inventory. However, if your process refines additional vegetable oil from off-site 

sources, recovers solvent from the off-site oil, and adds it to the on-site solvent 

inventory, then you must determine the quantity of recovered solvent and include 

it in the gallons of extraction solvent received. 

(5) Solvent inventory adjustments. In some situations, solvent losses determined 

directly from the measured solvent inventory and quantity of solvent received is 

not an accurate estimate of the “actual solvent loss” for use in determining 

compliance ratios. In such cases, you may adjust the total solvent loss for each 

normal operating period as long as you provide a reasonable justification for the 

adjustment. Situations that may require adjustments of the total solvent loss 

include, but are not limited to, situations in paragraph (a)(5) (ii) of this section:

(ii) Changes in solvent working capacity. In records you keep on-site, 

document any process modifications resulting in changes to the solvent 

working capacity in your vegetable oil production process. Solvent 

working capacity is defined in §63.2872. In general, solvent working 

capacity is the volume of solvent normally retained in solvent recovery 

equipment such as the extractor, desolventizer-toaster, solvent storage, 

working tanks, mineral oil absorber, condensers, and oil/solvent 

distillation system. If the change occurs during a normal operating period, 

you must determine the difference in working solvent volume and make a 

one-time documented adjustment to the solvent inventory. 

(b) Use Equation 1 of this section to determine the actual solvent loss occurring from

your affected source for all normal operating periods recorded within a calendar 

month. Equation 1 of this section follows: 

= (SOLV SOLV + SOLV SOLV )

SOLVE = Gallons of solvent in the inventory at the end of normal operating period “i” as 

determined in paragraph (a)(3) of this section. 

SOLVR = Gallons of solvent received between the beginning and ending inventory dates 

of normal operating period “i” as determined in paragraph (a)(4) of this section. 

SOLVA = Gallons of solvent added or removed from the extraction solvent inventory 

during normal operating period “i” as determined in paragraph (a)(5) of this section. 

N = Number of normal operating periods in a calendar month. 

(c) The actual solvent loss is the total solvent losses during normal operating periods for 

the previous 12 operating months. You determine your actual solvent loss by 

summing the monthly actual solvent losses for the previous 12 operating months. 

You must record the actual solvent loss by the end of each calendar month following 

an operating month. Use the actual solvent loss in Equation 2 of §63.2840 to 

determine the compliance ratio. Actual solvent loss does not include losses that occur 

during operating status periods listed in paragraphs (c)(1) through (4) of this section. 

If any one of these four operating status periods span an entire month, then the month 

is treated as nonoperating and there is no compliance ratio determination. 

(1) Nonoperating periods as described in paragraph (a)(2)(ii) of this section. 

(2) Initial startup periods as described in §63.2850(c)(2) or (d)(2). 

(3) Malfunction periods as described in §63.2850(e)(2). 

(4) Exempt operation periods as described in paragraph (a)(2)(v) of this section. 

§63.2854 How do I determine the weighted average volume fraction of HAP in the

actual solvent loss?

(a) This section describes the information and procedures you must use to determine the 

weighted average volume fraction of HAP in extraction solvent received for use in your 

vegetable oil production process. By the end of each calendar month following an 

operating month, determine the weighted average volume fraction of HAP in extraction 

solvent received since the end of the previous operating month. If you have determined 

the monthly weighted average volume fraction of HAP in solvent received for 12 or more 

operating months, then also determine an overall weighted average volume fraction of 

HAP in solvent received for the previous 12 operating months. Use the volume fraction 

of HAP determined as a 12 operating months weighted average in Equation 2 of 

§63.2840 to determine the compliance ratio. 
(b) To determine the volume fraction of HAP in the extraction solvent determined as a 12 

operating months weighted average, you must comply with paragraphs (b)(1) through (3) 

of this section: 

(1) Record the volume fraction of each HAP comprising more than 1 percent by 

volume of the solvent in each delivery of solvent, including solvent recovered 

from off-site oil. To determine the HAP content of the material in each 

delivery of solvent, the reference method is EPA Method 311 of appendix A 

of this part. You may use EPA Method 311, an approved alternative method, 

or any other reasonable means for determining the HAP content. Other 

reasonable means of determining HAP content include, but are not limited to, 

a material safety data sheet or a manufacturer’s certificate of analysis. A 

certificate of analysis is a legal and binding document provided by a solvent 

manufacturer. The purpose of a certificate of analysis is to list the test

methods and analytical results that determine chemical properties of the 

solvent and the volume percentage of all HAP components present in the 

solvent at quantities greater than 1 percent by volume. You are not required 

to test the materials that you use, but the Administrator may require a test 

using EPA Method 311 (or an approved alternative method) to confirm the 

reported HAP content. However, if the results of an analysis by EPA Method 

311 are different from the HAP content determined by another means, the 

EPA Method 311 results will govern compliance determinations. 

(2) Determine the weighted average volume fraction of HAP in the extraction 

solvent each operating month. The weighted average volume fraction of HAP 

for an operating month includes all solvent received since the end of the last 

operating month, regardless of the operating status at the time of the delivery. 

Determine the monthly weighted average volume fraction of HAP by 

summing the products of the HAP volume fraction of each delivery and the 

volume of each delivery and dividing the sum by the total volume of all 

deliveries as expressed in Equation 1 of this section. Record the result by the 

end of each calendar month following an operating month. Equation 1 of this 

section follows:

month.

(3) Determine the volume fraction of HAP in your extraction solvent as a 12 

operating months weighted average. When your source has processed oilseed for 

12 operating months, sum the products of the monthly weighted average HAP 

volume fraction and corresponding volume of solvent received, and divide the 

sum by the total volume of solvent received for the 12 operating months, as 

expressed by Equation 2 of this section. Record the result by the end of each 

calendar month following an operating month and use it in Equation 2 of 

§63.2840 to determine the compliance ratio. Equation 2 of this section follows:

month “i” as determined in accordance with paragraph (b)(1) of this section.

Total Received = Total gallons of extraction solvent received during the previous 12 

operating months. 

 

§63.2855 How do I determine the quantity of oilseed processed?

All oilseed measurements must be determined on an as received basis, as defined in 

§63.2872. The as received basis refers to the oilseed chemical and physical 

characteristics as initially received by the source and prior to any oilseed handling and 

processing. By the end of each calendar month following an operating month, you must 

determine the tons as received of each listed oilseed processed for the operating month. 

The total oilseed processed for an operating month includes the total of each oilseed 

processed during all normal operating periods that occur within the operating month. If 

you have determined the tons of oilseed processed for 12 or more operating months, then 

you must also determine the 12 operating months rolling sum of each type oilseed 

processed by summing the tons of each type of oilseed processed for the previous 12 

operating months. The 12 operating months rolling sum of each type of oilseed 

processed is used to calculate the compliance ratio as described in §63.2840.

 December 7, 2006 

(a) To determine the tons as received of each type of oilseed processed at your source, 

follow the procedures in your plan for demonstrating compliance to determine the 

items in paragraphs (a)(1) through (5) of this section: 

(1) The dates that define each operating status period. The dates that define each 

operating status period include the beginning date of each calendar month and the 

date of any change in the source operating status. If, prior to the effective date of 

this rule, your source determines the oilseed inventory on an accounting month 

rather than a calendar month basis, and you have 12 complete accounting months 

of approximately equal duration in a calendar year, you may substitute the 

accounting month time interval for the calendar month time interval. If you 

choose to use an accounting month rather than a calendar month, you must 

document this measurement frequency selection in your plan for demonstrating 

compliance, and you must remain on this schedule unless you request and receive 

written approval from the agency responsible for these NESHAP. The dates on 

each oilseed inventory log must be consistent with the dates recorded for the 

solvent inventory. 

(2) Source operating status. You must categorize the source operation for each 

recorded time interval. The source operating status for each time interval 

recorded on the oilseed inventory for each type of oilseed must be consistent with 

the operating status recorded on the solvent inventory logs as described in 

§63.2853(a)(2). 

(3) Measuring the beginning and ending inventory for each oilseed. You are 

required to measure and record the oilseed inventory on the beginning and ending 

dates of each normal operating period that occurs during an operating month. An 

operating month is any calendar month with at least one normal operating period. 

You must consistently follow the procedures described in your plan for 

demonstrating compliance, as specified in §63.2851, to determine the oilseed 

inventory on an as received basis and maintain readily available records of the 

oilseed inventory as described by §63.2862(c)(3). 

(4) Tons of each oilseed received. Record the type of oilseed and tons of each 

shipment of oilseed received and added to your on-site storage. 

(5) Oilseed inventory adjustments. In some situations, determining the quantity 

of oilseed processed directly from the measured oilseed inventory and quantity of 

oilseed received is not an accurate estimate of the tons of oilseed processed for 

use in determining compliance ratios. For example, spoiled and molded oilseed 

removed from storage but not processed by your source will result in an 

overestimate of the quantity of oilseed processed. In such cases, you must adjust 

the oilseed inventory and provide a justification for the adjustment. Situations 

that may require oilseed inventory adjustments include, but are not limited to, the 

situations listed in paragraphs (a)(5)(i) through (v) of this section: 

(i) Oilseed that mold or otherwise become unsuitable for processing. 

(ii) Oilseed you sell before it enters the processing operation. 

(iii) Oilseed destroyed by an event such as a process malfunction, fire, or 

natural disaster. 
(iv) Oilseed processed through operations prior to solvent extraction such 

as screening, dehulling, cracking, drying, and conditioning; but that are 

not routed to the solvent extractor for further processing. 

(v) Periodic physical measurements of inventory. For example, some

sources periodically empty oilseed storage silos to physically measure the 

current oilseed inventory. This periodic measurement procedure typically

results in a small inventory correction. The correction factor, usually less 

than 1 percent, may be used to make an adjustment to the source’s oilseed

inventory that was estimated previously with indirect measurement 

techniques. To make this adjustment, your plan for demonstrating 

compliance must provide for such an adjustment. 

(b) Use Equation 1 of this section to determine the quantity of each oilseed type 

processed at your affected source during normal operating periods recorded within a 

calendar month. Equation 1 of this section follows:

Where: 

SEEDB = Tons of oilseed in the inventory at the beginning of normal operating period “i”

SEEDE = Tons of oilseed in the inventory at the end of normal operating period “i” as 

determined in accordance with paragraph (a)(3) of this section.

SEEDR= Tons of oilseed received during normal operating period “i” as determined in 

accordance with paragraph (a)(4) of this section.

SEEDA= Tons of oilseed added or removed from the oilseed inventory during normal 

operating period “i” as determined in accordance with paragraph (a)(5) of this section.

N = Number of normal operating periods in the calendar month during which this type 

oilseed was processed. 

(c) The quantity of each oilseed processed is the total tons of each type of listed oilseed 

processed during normal operating periods in the previous 12 operating months. You 

determine the tons of each oilseed processed by summing the monthly quantity of each

oilseed processed for the previous 12 operating months. You must record the 12 

operating months quantity of each type of oilseed processed by the end of each calendar 

month following an operating month. Use the 12 operating months quantity of each type 

of oilseed processed to determine the compliance ratio as described in §63.2840. The 

quantity of oilseed processed does not include oilseed processed during the operating 

status periods in paragraphs (c)(1) through (4) of this section: 

(1) Nonoperating periods as described in §63.2853 (a)(2)(ii). 

(2) Initial startup periods as described in §63.2850(c)(2) or (d)(2). 

(3) Malfunction periods as described in §63.2850(e)(2). 

(4) Exempt operation periods as described in §63.2853 (a)(2)(v). 

(5) If any one of these four operating status periods span an entire calendar 

month, then the calendar month is treated as a nonoperating month and there is 

no compliance ratio determination.

demonstrating compliance. 

(iii) The compliance ratio is less than or equal to 1.00. 

§63.2861 What reports must I submit and when?

(a) Annual compliance certifications. The first annual compliance certification is due 12 

calendar months after you submit the notification of compliance status. Each subsequent 

annual compliance certification is due 12 calendar months after the previous annual 

compliance certification. The annual compliance certification provides the compliance 

status for each operating month during the 12 calendar months period ending 60 days 

prior to the date on which the report is due. Include the information in paragraphs (a)(1) 

through (6) of this section in the annual certification: 

(1) The name and address of the owner or operator. 

(2) The physical address of the vegetable oil production process. 

(3) Each listed oilseed type processed during the 12 calendar months period 

covered by the report. 

(4) Each HAP identified under §63.2854(a) as being present in concentrations 

greater than 1 percent by volume in each delivery of solvent received during the 

12 calendar months period covered by the report. 

(5) A statement designating the source as a major source of HAP or a 

demonstration that the source qualifies as an area source. An area source is a 

source that is not a major source and is not collocated within a plant site with 

other sources that are individually or collectively a major source. 

(6) A compliance certification to indicate whether the source was in compliance 

for each compliance determination made during the 12 calendar months period 

covered by the report. For each such compliance determination, you must include 

a certification of the items in paragraphs (a)(6)(i) through (ii) of this section: 

(i) You are following the procedures described in the plan for 

demonstrating compliance. 

(ii) The compliance ratio is less than or equal to 1.00. 

(b) Deviation notification report. Submit a deviation report for each compliance 

determination you make in which the compliance ratio exceeds 1.00 as determined 

under §63.2840(c). Submit the deviation report by the end of the month following the

(ii) The operating status of your source such as normal operation, 

nonoperating, initial startup period, malfunction period, or exempt 

operation for each recorded time interval. 

(iii) Record the gallons of extraction solvent in the inventory on the 

beginning and ending dates of each normal operating period. 

(iv) The gallons of all extraction solvent received, purchased, and 

recovered during each calendar month. 

(v) All extraction solvent inventory adjustments, additions or subtractions. 

You must document the reason for the adjustment and justify the quantity 

of the adjustment. 

(vi) The total solvent loss for each calendar month, regardless of the 

source operating status. 

(vii) The actual solvent loss in gallons for each operating month. 

(2) For the weighted average volume fraction of HAP in the extraction solvent, 

you must record the items in paragraphs (c)(2)(i) through (iii) of this section: 

(i) The gallons of extraction solvent received in each delivery. 

(ii) The volume fraction of each HAP exceeding 1 percent by volume in 

each delivery of extraction solvent. 

(iii) The weighted average volume fraction of HAP in extraction solvent 

received since the end of the last operating month as determined in 

accordance with §63.2854(b)(2). 

(3) For each type of listed oilseed processed, record the items in paragraphs

I. Background

 A. Emissions Unit

 Description: Final Vent and Fugitives 

 Identification: EP GP09 

 Facility: ADM, Des Moines 

 B. Applicable Regulation, Emission Limit, and Monitoring Requirements 

 Regulation No.: 40 CFR Part 63 Subpart GGGG 

 City of Des Moines Construction Permit #0093 

 567 IAC 23.1(4)”cg” 

 Hexane emission limit: 708.95 tons/yr 

 n-Hexane emission limit: 453.72 tons/yr 

 Monitoring Requirements: Mineral oil scrubber operating parameters. 
 ADM – Des Moines Soybean Plant 

 70 04-TV-020-M001 

 December 7, 2006 

 C. Control Technology

 Mineral oil scrubber (MOS) 

II. Monitoring Approach

 A. Indicators 

 Calculated 12-month rolling total hexane losses, mineral oil temperature and 

 rate will be used as indicators. 

 B. Measurement Approach 

 Mass-balance calculations will use the facility’s hexane purchase records. The 

 scrubber’s mineral oil flow rate and temperature are monitored. 

 C. Indicator Ranges 

 The indicator levels for the scrubber are a mineral oil flow rate not less than 10 

 gallons per minute into the absorber and a mineral oil temperature not less than 

 180 degrees F into the stripper. These indicator levels are during normal 

 operations and do not include periods of startup or shutdown of the mineral oil 

 system 

 D. QIP (Quality Improvement Plan) Threshold 

 The QIP thresholds are six excursions total of either the mineral oil flow rate or 

 the mineral oil temperature in one six month reporting period or one instance of 

 12-month rolling VOC emissions greater than 708.95 tons. The 12-month 

 rolling totals will be recalculated and recorded each month. 

 E. Performance Criteria 

 

 Data representativeness: The mineral oil scrubber is designed to operate at 

 maximum control efficiency at specific mineral oil flow rate and temperature 

 ranges. Oil flow entering the absorber shall be measured for flow rate and 

 temperature shall be measured in the oil entering the stripper. These parameters 

 are recorded a minimum of once per day. If the flow rate or 

 temperature have drifted out of the optimal efficiency range, this is an indication 

 of the potential for increased hexane emissions. Facility hexane loses, 

 determined from hexane make-up solvent purchases, is representative of 

 the scrubber’s operation. 

 Verification of operational status: Mineral oil flow rate and temperature are 

 monitored to insure proper operation of the mineral oil scrubber. The mineral oil 

 system will be maintained in good working condition according to the 

 appropriate O&M procedures. 

 
 ADM – Des Moines Soybean Plant 

 71 04-TV-020-M001 

 December 7, 2006 

QA/QC practices and criteria: Monitoring the mineral oil flow rate and temperature 

will serve to alert the facility in circumstances when the mineral oil 

 scrubber experiences short-term excursions. Any recorded flow rate or 

 temperature outside of the indicator range during normal operations will signify 

 an excursion. Normal operations do not include periods of startup or shutdown of 

 the mineral oil system. 

 When an excursion occurs, corrective action will be initiated within 8 hours, 

 beginning with an evaluation of the occurrence to determine the action required. 

 After any necessary corrective action has been taken, a follow-up check will be 

 performed to insure that the indicator is within the indicator range. 

 Monitoring frequency and data collection procedures: The mineral oil flow rate 

 and temperature sensors provide real-time readings which are recorded a minimum 

 of once per day when the facility’s emission unit is in operation. Facility hexane 

 losses will be calculated using material mass balance. Hexane losses will be 

 assumed to equal all new hexane purchases made to maintain the facility’s 

 inventory. Each month, the facility calculates and records the 12-month 

 rolling total hexane emissions for the facility. 

 

III. Justification

 A. Background 

 This facility processes various oilseeds to extract vegetable oils. The pollutant 

 specific emission unit is the seed oil extraction and refinement unit that uses 

 hexane as solvent. Hexane emissions are controlled by a Mineral Oil Scrubber. 

 B. Rationale for Selection of Performance Indicator 

 The scrubber’s mineral oil flow rate and temperature were selected as the 

 performance indicators as they are indicative of operation of the scrubber in a 

 manner necessary to maximize collection and reuse of hexane and minimize 

 emissions. An excursion of these indicators out of the optimal operating range 

 indicates a possibility of reduced performance of the scrubber. 

 Facility 12-month rolling total hexane emissions are used as long-term 

 performance indicator. 

 C. Rationale for Selection of Indicator Level 

 The mineral oil flow rate into the absorber is > 10 gallons per minute and the 

 mineral oil temperature into the stripper is >180°F. These indicator ranges were 

 selected because operation of the scrubber outside the optimal ranges for these 

 parameters is indicative of a potential for increased hexane emissions. 

 
 ADM – Des Moines Soybean Plant 

 72 04-TV-020-M001 

 December 7, 2006 

The selected QIP thresholds are six excursions total of either the mineral oil 

 flow rate or the mineral oil temperature in one six month reporting period or one 

 instance in which the facility’s 12-month rolling VOC emissions exceed 

 708.95 tons. The 12-month rolling totals will be recalculated and recorded each 

 month. This level is the facility’s permitted annual emissions limit for hexane. 

 If a QIP threshold is exceeded once, a QIP will be developed and implemented.

 Authority for Requirement – 567 IAC 22.108(3) 

The owner of this equipment or the owner’s authorized agent shall provide written notice 

to the Director, not less than 30 days before a required stack test or performance 

evaluation of a continuous emission monitor. Results of the test shall be submitted in 

writing to the Director in the form of a comprehensive report within 6 weeks of the 

completion of the testing. 567 IAC 25.1(7) 

EP HR03 shall be visually checked for observable emissions once every week by a 

designated observer. The observation shall be taken while the equipment is operating at 

or near full capacity. The observation shall be noted in a log book, which shall state the 

date, time, observer’s signature, and whether any emissions were observed. If visible 

emissions are observed, corrective action will be taken as soon as possible, but no later 

than eight hours from the observation of visible emissions. If corrective action does not 

return the observation to no visible emissions, then a Method 9 observation will be 

required. If an opacity >20% is observed, this would be a violation and corrective action 

will be taken as soon as possible, but no later than eight hours from the observation of 

visible emissions. If weather conditions prevent the observer from conducting an opacity 

observation, the observer shall note such conditions on the data observation sheet. At 

least three attempts shall be made to retake opacity readings at approximately 2-hour 

intervals throughout the day. If all observation attempts for a week have been 

unsuccessful due to weather, an observation shall be made the next operating day where 

weather permits. The log book will be maintained on site for 5 years and be made 

available to representatives of Polk County AQD upon request.

requirements listed below. 

EP MP07 shall be visually checked for observable emissions once every week by a 

designated observer. The observation shall be taken while the equipment is operating at 

or near full capacity. The observation shall be noted in a log book, which shall state the 

date, time, observer’s signature, and whether any emissions were observed. If visible 

emissions are observed, corrective action will be taken as soon as possible, but no later 

than eight hours from the observation of visible emissions. If corrective action does not 

return the observation to no visible emissions, then a Method 9 observation will be 

required. If an opacity >20% is observed, this would be a violation and corrective action 

will be taken as soon as possible, but no later than eight hours from the observation of 

visible emissions. If weather conditions prevent the observer from conducting an opacity 

observation, the observer shall note such conditions on the data observation sheet. At 

least three attempts shall be made to retake opacity readings at approximately 2-hour 

intervals throughout the day. If all observation attempts for a week have been 

unsuccessful due to weather, an observation shall be made the next operating day where 

weather permits. The log book will be maintained on site for 5 years and be made 

available to representatives of Polk County AQD upon request. 

Agency Approved Operation & Maintenance Plan Required? Yes No 

 

Facility Maintained Operation & Maintenance Plan Required? Yes No 

Facility operation and maintenance plans must be sufficient to yield reliable data from 

the relevant time period that are representative of the source’s compliance with the 

applicable requirements. 

Facility operation and maintenance plans are to be developed by the facility within six 

(6) months of the issuance date of this permit and the data pertaining to the plan 

maintained on site for at least 5 years. The plan and associated recordkeeping provides

Operational Limits & Requirements

The owner/operator of this equipment shall comply with the operational limits and 

requirements listed below.

 

Operating Limits:

A. The multi-bed fluidized combustion (MBC) boiler is limited to a maximum heat 

input rating of 192.0 million BTUs per hour (MMBTU/hr). 

B. The approved boilers are restricted to coal, with gas or oil startup. “Coal” means 

any subbituminous coal supply, any bituminous coal supply, or blends composed 

of such coal supplies. 

C. If a turbine/generator is to be installed as part of the project, the turbine shall be a 

conventional, unfired, steam turbine. 

Operating Condition Monitoring: 

A. Quarterly written excess emission (opacity) reports shall be submitted to the state 

per 40 CFR 60.7(c) and 40 CFR 60.49b(h). The quarterly report is based on the 

continU0us emission monitoring records and is required even if the excess 

emissions were “zero.” 

B. Quarterly written excess carbon monoxide emission reports shall be submitted 

and postmarked not more than thirty (30) days following the last monitoring day 

of the reported quarter. The quarterly report is based on the continuous emission 

monitoring records and is required even if the excess emissions were “zero.” 

C. Hourly emission rate data shall be recorded and used by the owner or operator to 

calculate compliance with the applicable emission rates and percent reductions for 

the specified averaging times. After completion of the initial performance tests, 

compliance with the SO2 and NOx emission rate limitation and the SO2 percent 

reduction requirements shall be calculated as the average of all valid hourly 

emission rate data and valid hourly SO2 percent reduction data for the 30 previous 

boiler operating days during which each standard applies. The owner shall 

calculate a new 30-day average at the end of each boiler operating day. 

Compliance with the SO2 standards shall be determined separately depending on 

the average inlet SO2 rate to the boiler. SO2 emission rate and percent reduction 

data collected under the two inlet SO2 rate ranges shall not be intermixed except 

when determining compliance with the short term standards (i.e., 24-hour 

standard). 

D. The weight percent sulfur and gross heating value, as obtained through daily fuel 

sampling and analysis (FSA) of coal contained in the day bunker shall be used to 

calculate an equivalent inlet SO2 rate using the following equation. 

Equivalent Inlet SO2 Rate = (%S/GHV) * K 

%S = Weight percent sulfur of coal contained in bunker 

GHV = Gross heating value of coal contained in bunker 

K = 20,000 (lb*BTUs)/(%*MMBTUs) 
 ADM – Des Moines Soybean Plant 

 129 04-TV-020-M001 

 December 7, 2006 

The facility shall use the equivalent SO2 rate to calculate each hourly percent 

reduction during the boiler operating day. 

E. In order to determine continuous compliance with the Beryllium (Be) standard, an 

“as-fired” coal sample shall be taken semi-annually or whenever a new coal 

supply is burned in the boiler (whichever is more frequent), and shall be analyzed 

for Be content. The owner shall accomplish said sampling within one (1) week of 

the semi-annual deadline or change of coal supply. The results of the analysis 

shall be submitted to the PSD implementing agency within two (2) weeks of the 

date of collection of the sample. The sampling and analysis procedures after the 

initial verification of compliance shall be the same as performed on the sample 

collected during the initial Be-related stack testing of the unit. A “new coal 

supply” shall be defined as coal obtained from a different mine or supplier. 

Continuous Emission Monitoring: 

In accordance with NSPS Subpart Db and 40 CFR 60.13, the facility shall install, 

calibrate, maintain, and operate a continU0us opacity monitoring system (COMS) for 

measuring the opacity of the emissions discharged to the atmosphere and record the 

output of the system. The system shall be designed to meet the 40 CFR 60, Appendix B, 

Performance Specification 1 (PS1). 

Compliance with the carbon monoxide emission limits of this permit shall be 

continuously demonstrated by the owner through the use of a continU0us emission 

monitoring system (CEMS). Therefore, the facility shall install, calibrate, maintain, and 

operate a CEMs for measuring carbon monoxide emissions discharged to the atmosphere 

and record the output of the system. The system shall be designed to meet the 40 CFR 

60, Appendix B, Performance Specification 4 (PS4). 

Compliance with the sulfur dioxide (SO2), nitrogen oxides (NOx), and SO2 percent 

reduction requirements of this permit shall be continuously demonstrated by the owner 

through the use of a CEMs. Therefore, the facility shall install, calibrate, maintain, audit, 

and operate a CEMs for measuring SO2, NOx, and the appropriate diluent gas (oxygen or 

carbon dioxide) emissions discharged to the atmosphere and record the output of the 

system. The system shall be designed to meet the 40 CFR 60.13 requirements, the 40 

CFR 60, Appendix B, Performance Specifications 2 and 3 (PS2 and PS3), and the 40 

CFR Part 60 Appendix F requirements. 

The CEMs shall be operated and data recorded during any period any fuel is combusted 

in the boiler. Hourly parts-per-million data recorded by the pollutant CEMs shall be 

converted to lb-pollutant per million BTUs (lb/MMBTUs) heat input using the equations 

and methodology specified in 40 CFR 60, Appendix A, Method 19. 
 ADM – Des Moines Soybean Plant 

 130 04-TV-020-M001 

 December 7, 2006 

The owner shall successfully complete SO2 and NOx CEMs performance evaluations 

(including relative accuracy and calibration drift assessment) under the following two 

conditions: (1) firing a coal or blend of coals that results, or can reasonably be expected 

to result, in controlled emissions between 0.0 and 0.6 lb-SO2/MMBTUs; and (2) firing a 

coal or blend of coals that results, or can reasonably be expected to result, in controlled 

emissions 0.60 or greater lb-SO2/MMBTUs. 

Successful performance tests in at least one of the above-specified emission ranges shall 

be completed prior to beginning the initial compliance demonstration required under 

Condition 12 of IDNR Construction Permit 87-A-013PS1. The remaining performance 

evaluation may be run during any of the quarterly Appendix F audits, or at any other 

time, but must be completed no later than 90 days after any fuel switch which results, or 

can reasonably be expected to result, in controlled SO2 emissions in the range for which a 

successful performance evaluation has not previously been completed. 

Fuel Sampling and Analysis: 

The owner shall install, operate and maintain a fuel sampling and analysis (FSA) system 

to collect “as-fired” fuel data. The FSA system shall meet or exceed the design and 

performance specifications set forth in 40 CFR 60, Appendix A, Method 19 

(incorporating by reference of ASTM method D2234-76, et al.). As specified by Method 

19, at least a minimum number and weight of sample increments shall be collected at a 

location immediately preceding the day bunker (downstream of all blending operations), 

composited, and analyzed daily. Coal analyses shall be conducted for weight percent 

sulfur (%S) and gross heat value (GHV, expressed in BTUs/lb-coal). 

The owner may develop an in-house coal analysis program or may send collected 

samples to a laboratory for analysis. In either case, the analytical results shall be 

available to the MBC boiler operator within 72 hours of the sample collection time. To 

ensure that coal analyses are performed in accordance with ASTM methods, the permitissuing agency will require the owner to conduct periodic analyses of quality assurance 

audit coal samples provided by EPA. 

The “as-fired” fuel data will be used to determine the equivalent hourly average SO2 inlet 

rate to the boiler, and will be used in conjunction with the SO2 CEMS emission rate data 

to determine compliance with the SO2 30-day rolling percent reduction limit. The 

“equivalent hourly average SO2 inlet rate” means the sulfur input rate expressed in terms 

of “lbs SO2 /MMBTUs heat input” based on the assumption of 100 percent conversion of 

sulfur to SO2.

Periodic Monitoring Requirements 

The owner/operator of this equipment shall comply with the periodic monitoring 

requirements listed below. 

EP C06a and C06b shall be visually checked for observable emissions once every week 

by a designated observer. The observation shall be taken while the equipment is 

operating at or near full capacity. The observation shall be noted in a log book, which 

shall state the date, time, observer’s signature, and whether any emissions were observed. 

If visible emissions are observed, corrective action will be taken as soon as possible, but 

no later than eight hours from the observation of visible emissions. If corrective action 

does not return the observation to no visible emissions, then a Method 9 observation will 

be required. If an opacity >0% is observed, this would be a violation and corrective 

action will be taken as soon as possible, but no later than eight hours from the 

observation of visible emissions. If weather conditions prevent the observer from 

conducting an opacity observation, the observer shall note such conditions on the data 

observation sheet. At least three attempts shall be made to retake opacity readings at 

approximately 2-hour intervals throughout the day. If all observation attempts for a week 

have been unsuccessful due to weather, an observation shall be made the next operating 

day where weather permits. The log book will be maintained on site for 5 years and be 

made available to representatives of Polk County AQD upon request. 

Agency Approved Operation & Maintenance Plan Required? Yes No 

 

Facility Maintained Operation & Maintenance Plan Required? Yes No 

Facility operation and maintenance plans must be sufficient to yield reliable data from 

the relevant time period that are representative of the source’s compliance with the 

applicable requirements. 

Facility operation and maintenance plans are to be developed by the facility within six 

(6) months of the issuance date of this permit and the data pertaining to the plan 

maintained on site for at least 5 years. The plan and associated recordkeeping provides 

documentation of this facility’s implementation of its obligation to operate according to 

good air pollution control practice.

G14. Excess Emissions and Excess Emissions Reporting Requirements 

1. Excess Emissions. Excess emission during a period of startup, shutdown, or cleaning 

of control equipment is not a violation of the emission standard if the startup, shutdown 

or cleaning is accomplished expeditiously and in a manner consistent with good practice 

for minimizing emissions. Cleaning of control equipment which does not require the 

shutdown of the process equipment shall be limited to one six-minute period per onehour period. An incident of excess emission (other than an incident during startup, 

shutdown or cleaning of control equipment) is a violation. If the owner or operator of a 

source maintains that the incident of excess emission was due to a malfunction, the owner 

or operator must show that the conditions which caused the incident of excess emission 

were not preventable by reasonable maintenance and control measures. Determination of 

any subsequent enforcement action will be made following review of this report. If 

excess emissions are occurring, either the control equipment causing the excess emission 

shall be repaired in an expeditious manner or the process generating the emissions shall 

be shutdown within a reasonable period of time. An expeditious manner is the time 

necessary to determine the cause of the excess emissions and to correct it within a 

reasonable period of time. A reasonable period of time is eight hours plus the period of 

time required to shut down the process without damaging the process equipment or 

control equipment. In the case of an electric utility, a reasonable period of time is eight 

hours plus the period of time until comparable generating capacity is available to meet 

consumer demand with the affected unit out of service, unless, the director shall, upon 

investigation, reasonably determine that continued operation constitutes an unjustifiable 

environmental hazard and issue an order that such operation is not in the public interest 

and require a process shutdown to commence immediately.

2. Excess Emissions Reporting 

a. Oral Reporting of Excess Emissions. An incident of excess emission (other than an 

incident of excess emission during a period of startup, shutdown, or cleaning) shall be 

reported to the appropriate field office of the department within eight hours of, or at the 

start of the first working day following the onset of the incident. The reporting exemption 

for an incident of excess emission during startup, shutdown or cleaning does not relieve 

the owner or operator of a source with continuous monitoring equipment of the obligation 

of submitting reports required in 567-subrule 25.1(6). An oral report of excess emission 

is not required for a source with operational continuous monitoring equipment (as 

specified in 567-subrule 25.1(1) ) if the incident of excess emission continues for less 

than 30 minutes and does not exceed the applicable visible emission standard by more 

than 10 percent opacity. The oral report may be made in person or by telephone and shall 

include as a minimum the following: 

i. The identity of the equipment or source operation from which the excess emission 

originated and the associated stack or emission point. 

ii. The estimated quantity of the excess emission. 

iii. The time and expected duration of the excess emission. 

iv. The cause of the excess emission. 

v. The steps being taken to remedy the excess emission. 

vi. The steps being taken to limit the excess emission in the interim period. 

b. Written Reporting of Excess Emissions. A written report of an incident of excess 

emission shall be submitted as a follow-up to all required oral reports to the department 

within seven days of the onset of the upset condition, and shall include as a minimum the 

following: 

i. The identity of the equipment or source operation point from which the excess emission 

originated and the associated stack or emission point. 

ii. The estimated quantity of the excess emission. 

iii. The time and duration of the excess emission. 

iv. The cause of the excess emission. 

v. The steps that were taken to remedy and to prevent the recurrence of the incident of 

excess emission. 

vi. The steps that were taken to limit the excess emission. 

vii. If the owner claims that the excess emission was due to malfunction, documentation 

to support this claim. 567 IAC 24.1(1)-567 IAC 24.1(4) and Chapter V, Article VI, 5-17

3. Emergency Defense for Excess Emissions. For the purposes of this permit, an 

“emergency” means any situation arising from sudden and reasonably unforseeable 

events beyond the control of the source, including acts of God, which requires immediate 

corrective action to restore normal operation, and that causes the source to exceed a 

technology-based emission limitation under the permit due to unavoidable increases in 

emissions attributable to the emergency. An emergency shall not include noncompliance, to the extent caused by improperly designed equipment, lack of preventive 

maintenance, careless or improper operation or operator error. An emergency constitutes 

an affirmative defense to an action brought for non-compliance with technology based 

limitations if it can be demonstrated through properly signed contemporaneous operating 

logs or other relevant evidence that: 

a. An emergency occurred and that the permittee can identify the cause(s) of the 

emergency; 
 ADM – Des Moines Soybean Plant 

 149 04-TV-020-M001 

 December 7, 2006 

b. The facility at the time was being properly operated; 

c. During the period of the emergency, the permittee took all reasonable steps to 

minimize levels of emissions that exceeded the emissions standards or other requirements 

of the permit; and 

d. The permittee submitted notice of the emergency to the director by certified mail 

within two working days of the time when the emissions limitations were exceeded due 

to the emergency. This notice must contain a description of the emergency, any steps 

taken to mitigate emissions, and corrective actions taken. 567 IAC 22.108(16) 

G15. Permit Deviation Reporting Requirements 

A deviation is any failure to meet a term, condition or applicable requirement in the 

permit. Reporting requirements for deviations that result in a hazardous release or excess 

emissions have been indicated above (see G13 and G14). Unless more frequent deviation 

reporting is specified in the permit, any other deviation shall be documented in the semiannual monitoring report and the annual compliance certification (see G4 and G5). 567 

IAC 22.108(5)"b" 

G16. Notification Requirements for Sources That Become Subject to NSPS and 

NESHAP Regulations 

During the term of this permit, the permittee must notify the department of any source 

that becomes subject to a standard or other requirement under 567-subrule 23.1(2) 

(standards of performance of new stationary sources) or section 111 of the Act; or 567-

subrule 23.1(3) (emissions standards for hazardous air pollutants), 567-subrule 23.1(4) 

(emission standards for hazardous air pollutants for source categories) or section 112 of 

the Act. This notification shall be submitted in writing to the department pursuant to the 

notification requirements in 40 CFR Section 60.7, 40 CFR Section 61.07, and/or 40 CFR

22.110(1) 

2. Such changes do not include changes that would violate applicable requirements or 

contravene federally enforceable permit terms and conditions that are monitoring 

(including test methods), record keeping, reporting, or compliance certification 

requirements. 567 IAC 22.110.(2)

3. Notwithstanding any other part of this rule, the director may, upon review of a notice, 

require a stationary source to apply for a Title V permit if the change does not meet the 

requirements of subrule 22.110(1). 567 IAC 22.110.(3)

4. The permit shield provided in subrule 22.108(18) shall not apply to any change made 

pursuant to this rule. Compliance with the permit requirements that the source will meet 

using the emissions trade shall be determined according to requirements of the state 

implementation plan authorizing the emissions trade. 567 IAC 22.110.(4)

5. Aggregate Insignificant Emissions. The permittee shall not construct, establish or 

operate any new insignificant activities or modify any existing insignificant activities in 

such a way that the emissions from these activities no longer meet the criteria of 

aggregate insignificant emissions. If the aggregate insignificant emissions are expected to 

be exceeded, the permittee shall submit the appropriate permit modification and receive 

approval prior to making any change. 567 IAC 22.103.(2) 

6. No permit revision shall be required, under any approved economic incentives,
