### 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 con veying

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 t he 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 t o South storage (P

- 2) by r eceiving 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.ADM – Des Moines Soybean Plant

## 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-solvent ize, dry and grind the resulting meal. The meal and hulls/pellets are transferred to stor age 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 re finery for further processing. The refining process removes impuritie s and residual solvent in the oil.ADM – Des Moines Soybean Plant

If weather conditions pr event the observer from conducting an opacity observation, the observer shall note such c onditions on the data observation sheet. At least three attempts shall be made to reta ke opacity readings at approximately 2-hour intervals throughout the day. If all obse rvation 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 represen tative of the source’s compliance with the applicable requirements.

December 7, 2006 (b) When your source has processed listed oils eed 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 calcu lating 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 initia l startup period or malfunction period subject to §63.2850, then you must categorize the mont h as an operating month, as defined in §63.2872. (2) The 12-month compliance ratio may in clude 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 proce sses no listed oilseed for an entire calendar month, then you mu st categorize the month as a nonoperating month, as defined in §63.2872. Exclude any no noperating months from the compliance

ratio determination. (4) If your source is subject to an initi al 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 subj ect 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 sp ecialty soybean, the solvent loss factor you use to determine the compliance ratio may change each operating month depending on the tons of oilseed processe d during all normal operating periods in a 12 operating month period. (c) If the compliance ratio is le ss than or equal to 1.00, your source was in compliance

with the HAP emission requirements for th e 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 hazard ous 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, shutdo wn and malfunction (SSM) plan in accordance with the provisions in §63.2852. (4) Maintain all th e 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 tes ting 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 operati on, and the schedules for demonstrating compliance for existing sources under normal ope ration 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 follo w 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 unifo rm 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 operat ional. If you make any changes to the plan for demonstrating compliance, then you must keep all previous versions of the plan and make th em 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 addres s of the vegetable oi l 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 th e 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 th e SSM plan by reference in your source’s title V permit and keep the SSM plan on-site an d readily available as long as the source is operational. The SSM plan provides detailed procedures for opera ting 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 pl an, 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 prev ious operating month. The total solvent loss for an operating month includes all solven t losses that occur during normal operating periods within the operating mont h. If you have determined so lvent losses for 12 or more operating months, then you must also determ ine the 12 operating months rolling sum of actual solvent loss in gallons by summing the mo nthly 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.ADM – Des Moines Soybean Plant
57 04-TV-020-M001

December 7, 2006 (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 th is section: (1) The dates that define each operating status period during a calendar month

. The dates that define each operating st atus 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 sa me operating status during an entire calendar month, these dates are the be ginning and ending dates of the calendar month. If, prior to the e ffective 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 cal endar month time interval. If you choose to use an accounting month rather than a calendar month, you must document this measurement freque ncy selection in your plan for demonstrating compliance, and you must remain on this schedule unless you request and receive written approval fr om 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 op erating 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 subj ect 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 processe s agricultural products

not defined as listed oilseed an exempt period.(3) Measuring the beginning and ending solvent inventory . You are req u ired to

m easure and record the s o lvent inven t or y on the beginning and ending dates of

each norm a l operating p e riod that occurs during an operating m onth. An operating month is any calendar m o n t h with at least one norm a l operating period.

You m u st consisten tly f o llow the p r o cedures described in your plan for

dem onstrating com p liance, as specified in §63.2851, to determ ine the extraction solvent inventory, and m a intain readily av ailable records of th e actua l solv ent loss inventory, as described in §63.2862(c)(1). In general, you m u st m easure and record the solvent inventory only when th e source is actively processing any type of agricultural product. When the source is not active, som e or all of the solvent working cap acity is trans f erred to so lv ent sto r age tanks which can artificially

inf l ate the s o lvent inven t ory. (4) Gallon s of extraction solvent rece ived . Recor d the to tal g a llons of extraction solvent received in each shipm e nt. For m o st processes, th e gallons of solv ent received rep r esents purchases of delive red solv en t added to th e solven t sto r age inventory. However, if your process refines additional ve getable oil from off-site

sources, rec overs solv en t f r om the off

- site o il, an d adds it to the on-site so lvent inventory, then you m u st determ ine the qua ntity of recovered solvent and include it in the ga llons of extra c tion so lven t rec e ived. (5) Solvent inventory adjustm e nts . In som e situations, so lven t losse s dete rm ined directly fro m the m easured solven t invent ory an d quantity of solvent rece ived is

not an accu rate es tim ate of the “actual solven t los s ” for use in determ ining

com p liance ratios. In su ch cases, yo u m a y adjust the to tal so lvent loss for each

norm a l operating period as long as you provi de a reasonable justification f o r the adjustm e nt. Situations that m a y require ad justm e nts of the total so lvent loss include, bu t are not lim ited to, situations in parag r aph (a )(5) ( ii) of th is se ction : (ii) Changes in solvent working cap acity. In records you keep on-site,

docum ent any process modifications re sulting in changes to the solv ent working capacity in your vegetable oil production process. Solvent working cap acity is defined in §63.2872. In general, solvent working capacity is the volum e of solvent nor m a lly retain ed in solv ent recove ry equipm ent such as the extractor, de s o lventizer-to a ster, solven t storage, working tanks, m i neral oil absorber, condensers, and oil/solvent distillation system . If the change oc curs during a norm al operating period,

you m u st determ ine the difference in working solvent volum e and m a ke a

one-tim e do cum e nted adjustm e nt to the solvent inventory. (b) Use Equation 1 of this sec tion to dete rm ine the ac tual so lvent loss occu rring f r om your affected source for all norm al opera ting periods recorded within a calendar month. Equation 1 of this section follows:

SOLV A = 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 solven t losses during normal operating periods for the previous 12 operating months. Y ou determine your actu al 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 lis ted in paragraphs (c)(1) th rough (4) of this section. If any one of these four operating status peri ods span an entire month, then the month is treated as nonoperating and there is no compliance ratio determination. (1) Nonoperating periods as described in pa ragraph (a)(2)(ii) of this section. (2) Initial startup peri ods 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 av erage volume fraction of HAP in extraction

solvent received since the end of the previous operating mont h. 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 mont hs weighted average in Equation 2 of §63.2840 to determine the compliance ratio.(b) To determ ine the volum e f r action of HAP in the extra c tion s o lvent de ter m ined as a 12 operating months weighted average, you m u st comply with paragr aphs (b)(1) through (3)

of

this sec tio n: (1) Record the v o lum e fraction of each HAP com p ri sing m o re than 1 percen t by

volum e of the solven t in each delivery of solvent, includ ing s o lvent recov e red

f r om off

- site oil. To dete rm ine the HAP content of the m a terial in e ach delivery of solvent, the reference m e thod is EPA Method 311 of appendix A of this part. You m a y us e EPA Met hod 311, an approved alternative m e thod, or any other reasonable m eans for de term ining the HAP content. Othe r reasonab l e m eans of determ ining HAP c ontent include, but are not lim ited to,

a m a terial sa f e ty data she e t or a m a nuf acturer’s certificate of analysis. A certificate of analys is is a legal a nd binding docum ent provided by a solvent

m a nufacturer. The purp o se of a certificat e of an alysis is to list the tes t

m e thods and analytical results that determ ine chem ical properties of the

solvent and the volum e p e rcentage of all HAP components present in the solvent at qu antities g r ea ter than 1 pe rcent by volu m e . You a r e not required

to test the m a terials that you use, but the Adm i nistrator m a y require a test using EPA Method 311 (or an approved alternative m e thod) to confirm th e reported HAP content. However, if th e results of an analysis by EPA Method

311 are different from the HAP content determ ined by another m eans, the

EPA Method 311 results will govern com p liance determ inatio ns. (2) Determ ine the weighted average vo lum e f r action of HAP in the extr actio n solvent each operating month. The wei ghted average volum e fraction of HAP for an operating m onth includes all solven t receiv ed since th e end of the last operating month, regardless of the operati ng statu s at th e tim e of the delivery.

Determ ine the m onthly weighted average volume fraction of HAP by summing the products o f the HAP volum e fraction of each delivery and the

volum e of e ach delivery and dividing the sum b y the total volum e of all deliveries as expressed in Equation 1 of th is sec t ion. Record the resu lt by the

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

All oils eed m easurem ents m u st be determ ined on an as received basis, as defined in §63.2872. The as received basis refers to the oilseed chem ical and physical

characteristics as in itially received b y the source and prior to a ny oilseed handling and processing. By the end o f each calen dar m onth following an operating month, you must

determ ine th e tons as rec e ived of eac h liste d oilseed processed for the operating m ont h. The total oilseed processed for an operating m onth include s th e tota l of ea ch oils eed processed during all norm a l operating periods th at occur within the operating m onth. If you have determ ined the tons of oilseed pro cessed for 12 or more operating m onths, then

you m u st also determ ine the 12 operating m onths 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 m onths rolling sum o f e ach type of oilseed processed is used to calc ulate the compliance ratio as described in §63.2840.

If, prio r to the effective date of this rule, your source determines the oilseed inventory on an accounting month rather than a calendar month basis, a nd you have 12 complete accounting months of approximately equal duration in a calendar year, you may substitute the accounting month time interval for the cal endar month time interval. If you choose to use an accounting month rather than a calendar month, you must document this measurement frequency sele ction in your plan for demonstrating compliance, and you must remain on this schedule unless you request and receive written approval from the agency respons ible 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 t ype of oilseed must be consistent with the operating status recorded on the solv ent 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 oils eed 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 pro cedures described in your plan for demonstrating compliance, as specified in §63.2851, to determine the oilseed inventory on an as received basis and ma intain readily availa ble 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. Fo r example, spoiled and molded oilseed removed from storage but not processe d 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 justif ication for the adjustment. Situations that may require oilseed inventory adjust ments include, but are not limited to, the situations listed in para graphs (a)(5)(i) through (v ) of this section: (i) Oilseed that mold or otherwise b ecome 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 solven t extraction such

as scre ening

, dehulling, crack ing, dr ying, and co ndition i ng; but tha t are not routed to the solv ent extr actor for further processing. (v) Periodic physical m e asurem ents of inventory. For exam p l e, som e sources periodically empty oilseed stor age silos to physically m easure the current oilseed inventory. This peri o d ic m easurem ent procedure typ i cally

results in a sm all inventory correction. The correction facto r , usually less than 1 percent, m a y be used to m a ke an adjus t m e nt to th e sou r ce’s o ils eed inventory that was estimated previo u s ly with indirect m easurem ent techniques. To m a ke this adjustm e nt, your plan for dem onstrating

com p liance must provid e for such an adjustm e nt. (b) Use Equation 1 of this section to dete rm ine the quantity of each oilseed type processed at your affected source during nor m a l operating periods recorded within a

calendar m o nth. Equation 1 of this section f o llo ws:

Where:

SEED B = To ns of oilseed in the inventory at the beginning of norm a l operating period “i”

N = Nu m b er of nor m a l operating periods in the calendar m onth during which this type oilseed was processed.

(c) The quantity of each oils eed processed is the total tons of each type of lis ted oilseed processed during norm a l operating periods in the previous 12 operating months. You

determ ine th e tons of eac h oilse e d processed by s u mm ing the monthly qua ntity of each oilseed processed for the previous 12 ope rating months. You must record the 12 operating months quantity of each ty pe of oilseed processed b y the end of each calend ar month following an operating m ont h. Use the 1 2 operating months quantity of each type of oilseed processed to determ ine the com p liance ratio as described in §63. 2840. The quantity of oilseed processed does not incl ude oilseed processed during the operating status periods in paragraphs (c)( 1) through (4) of this section: (1) Nonoperating periods as desc ribed in §63.2853 (a)(2)(ii). (2) Initial startup peri ods as described in §63.2850(c)(2) or (d)(2). (3) Malfunction periods as described in §63.2850(e)(2). (4) Exem pt operation periods as described in §63. 2853 (a)(2)(v). (5) If any one of these four operating status p e riod s span an en tire calendar month, then the calendar m onth is treated as a nonoperating month and there is

no com p liance ra tio de te rm ination.

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 te mperature 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 measur ed 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 in creased hexane emissions. Facility hexane loses,

determined from hexane make-up solvent purchases, is representative of the scrubber’s operation.

Verification of operationa l 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 incl ude periods of startup or shut down of the mineral oil system.

When an excursion occurs, corrective act ion 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 collecti on 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 va rious oilseeds to extract vegetable oils. The pollutant specific emission unit is th e seed oil extraction and re finement unit that uses

hexane as solvent. Hexa ne 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 ma ximize collection and reuse of hexane and minimize

emissions. An excursion of these indicators out of the optimal operating range indicates a possibi lity of reduced perfor mance of the scrubber.

Facility 12-month rollin g 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 scr ubber outside the optimal ranges for these parameters is indicative of a pot ential for increased hexane emissions.ADM – Des Moines Soybean Plant

72 04-TV-020-M001

December 7, 2006 The selected QIP thresholds are six excursi ons total of either the mineral oil

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

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

708.95 tons. The 12-month roll ing totals will be recalcul ated 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.

December 7, 2006 Operational Limits & Requirements The owner/operator of this equipment s hall 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 re port is based on th e continuous emission monitoring records and is required even if the excess emissions were “zero.”

C. Hourly emission rate data shall be record ed and used by the ow ner 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 SO 2 and NO

x emission rate limitation and the SO 2 percent reduction requirements shall be calculated as the average of all valid hourly emission rate data and valid hourly SO 2 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 th e end of each boiler operating day. Compliance with the SO 2 standards shall be determ ined separately depending on the average inlet SO 2 rate to the boiler. SO 2 emission rate and percent reduction

data collected under the two inlet SO 2 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 heatin g value, as obtained through daily fuel sampling and analysis (FSA) of coal contai ned in the day bunker shall be used to calculate an equivalent inlet SO 2 rate using the following equation.

Equivalent Inlet SO 2 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 SO 2 rate to calculate each hourly percent reduction during the boiler operating day.

E. In order to determine continuous complian ce 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 accomplis h 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 implementi ng agency within two (2) weeks of the date of collection of the sample. The sa mpling and analysis procedures after the initial verification of compliance shall be the same as performed on the sample collected during the initial Be-related st ack testing of the unit. A “new coal supply” shall be defined as coal obtain ed 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 disc harged 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 emi ssion limits of this permit shall be continuously demonstrated by the owner through the use of a continU0us emission monitoring system (CEMS). Therefore, the fac ility 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 sy stem shall be designed to meet the 40 CFR 60, Appendix B, Performance Specification 4 (PS4).

Compliance with the sulfur dioxide (SO 2 ), nitrogen oxides (NO

x ), and SO 2 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 SO 2 , NO

x , 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 Specifica tions 2 and 3 (PS2 and PS3), and the 40 CFR Part 60 Appendix F requirements.

The CEMs shall be operated and data record ed during any period an y 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 SO 2 and NO

x 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-SO 2 /MMBTUs; and (2) firing a coal or blend of coals that results, or can reas onably be expected to result, in controlled emissions 0.60 or greater lb-SO 2 /MMBTUs.

Successful performance tests in at least one of the above-specified emission ranges shall be completed prior to begi nning 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 quart erly 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 SO 2 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 anal yses shall be conducte d 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 e ither 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 th e owner to conduct periodic an alyses of quality assurance audit coal samples provided by EPA.

The “as-fired” fuel data will be used to determine the equivalent hourly average SO 2 inlet rate to the boiler, and will be used in conjunction with the SO 2 CEMS emission rate data to determine compliance with the SO 2 30-day rolling percent reduction limit. The “equivalent hourly average SO 2 inlet rate” means the sulfur input rate expressed in terms

of “lbs SO 2 /MMBTUs heat input” based on the a ssumption of 100 percent conversion of

sulfur to SO 2

December 7, 2006 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 standa rd if the startup, shutdown or cleaning is accomplished expeditiously and in a manner consistent with good practice for minimizing emissions. Cleaning of cont rol 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 (o ther than an incide nt 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 maintenan ce 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 ex cess 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 w ithout damaging the process equipment or control equipment.

December 7, 2006 2. Excess Emissions Reporting a. Oral Reporting of Excess Emissions. An in cident 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 th e department within ei ght hours of, or at the start of the first working day following the ons et of the incident. The reporting exemption for an incident of excess emission during star tup, shutdown or clean ing does not relieve the owner or operator of a source with con tinuous 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 inci dent of excess emission continues for less than 30 minutes and does not exceed the appl icable 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 sour ce 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.

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, incl uding 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 emergenc y. An emergency shall not include noncompliance, to the extent caused by improperl y designed equipment, lack of preventive maintenance, careless or improper operation or operator error. An emergency constitutes

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

limitations if it can be demonstrated thr ough 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
