### GRAIN ELEVATOR AND PROCESSOR NSPS INDUSTRY SURVEY

INTRODUCTION AND GENERAL INSTRUCTIONS

This survey form is to be completed by a respondent for each of its wholly owned facilities as described in the following four paragraphs (A-D), using the definitions at the end of this introductory section. Respondents must meet the requirements of paragraphs A, B, and C.
A. This survey is limited to the following facilities: any “grain elevator” that would constitute a “grain terminal elevator” or a “grain storage elevator” (as those terms are defined by Subpart DD (40 CFR 60.301)) if only permanent storage or both permanent and temporary storage at the grain elevator are taken into account. A respondent need not provide data for any facility not possessing this type of grain elevator.
B. EPA is interested in obtaining information about the following categories of grain elevators:
(1) Country grain elevators with storage capacity^ ≥ 2,500,000 bushels (2) Other stand-alone elevators with storage capacity^ ≥ 2,500,000 bushels (3) Wheat flour mill elevators * (4) Wet corn mill elevators * (5) Dry corn mill (human consumption) elevators * (6) Rice mill elevators * (7) Soybean oil extraction elevators *

^”Storage capacity” may include only permanent storage c apacity, or it may include both permanent and temporary storage capacity.
*Grain elevators in categories 3-7 above must have storage capacity of ≥ 1,000,000 bushels.
For each of the above seven categories, a respondent must submit a response for at least five facilities under its control. If a respondent has less than five facilities in a particular category, the respondent must provide information for all of its facilities in that category.C. EPA is also interested in obtaining inform ation about the following types of facilities:

 Grain elevators located in each EPA Region.

 Five storage combinations:

- Grain elevator alone

- Grain elevator w/emergency storage

- Grain elevator w/temporary storage

- Grain elevator w/emergency and temporary storage

- Grain elevator w/barge unloading

 Facilities handling multiple grains.

 Facilities handling only one grain.
A respondent must submit a response for each of the facilities listed below to the extent it has any such facility under its control for each of the 7 categories listed in paragraph B:

 At least one facility in each Region;

 At least one facility with each of the grain storage combinations;

 At least one facility that handles multiple grains; and

 At least one facility that handles only one grain.
For example, if a respondent has 18 facilities in t he country grain elevator category, and 10 are in EPA Region 5 and eight are in EPA Region 6, the respondent shall provide information for a minimum of five grain elevators. At least one elevator must be in Region 5 and one in Region 6. In addition, if applicable, the respondent shall provide information on at least one facility with each of the five grain storage combinations. The respondent must also provide information for at least one facility that handles multiple grains and one that handles only one grain. In this example, assuming the respondent owned each of the different types of grain elevators of interest to EPA, it is possible to meet the EPA requirements with five facilities responding if the five chosen facilities can meet multiple requirements (e.g., handling multiple grains in EPA Region 5 and using each of the 5 storage methods). However, it may be necessary to provided additional facility respons es to meet the EPA requirements if facilities cannot meet multiple EPA requirements.
D. The total number of facilities for a respondent may exceed 35 (five facilities in each of the seven categories) when including the regional, combination, and grain information. However, no respondent is required to submit information about more than 51 facilities.
Since one of the goals of this survey is to gather data on temporary storage facilities, EPA encourages respondents to exercise any discretion afforded by paragr aphs A-D above in favor of submitting data on such facilities. For the same reason, EPA encourages respondents to include along with their required responses to this survey any supplemental data on such facilities that may go beyond the bounds of this survey but nevertheless would be helpful to EPA in understanding tem porary storage facilities fully from the standpoint of Subpart DD.
This survey is provided in paper format and by first-class mail. However, you may opt to complete this survey either in paper format or in electronic format. To obtai n an electronic file (in Microsoft Word) to compile your responses, please contact Bill Schrock at schrock.bill@epa.gov . Please submit complete responses to Bill Schrock within 60 days after receipt by first-class mail. Any request for an extension of that 60-day period must be submitted to Bill Schrock within 30 days after rece ipt by first-class mail. Extensions will not be granted except upon a showing of undue hardship and then only for the minimum time reasonably necessary.
It is important to note that, throughout this document, we have used the terms “permanent storage,” “temporary storage” and “emergency storage” to differentiate between those structures typically constructed of concrete and topped with metal roofs and the pyramid shaped storage uni ts typically with low concrete walls and a vinyl top. The use of the terms “permanent storage” and “temporary storage” is strictly to reflect the currentreceipt by first-class mail. Any request for an extension of that 60-day period must be submitted to Bill Schrock within 30 days after receipt by first-class mail. Extensions will not be granted except upon a showing of undue hardship and then only for the minimum time reasonably necessary.
It is important to note that, throughout this document, we have used the terms “permanent storage,” “temporary storage” and “emergency storage” to differentiate between those structures typically constructed of concrete and topped with metal roofs and the pyramid shaped storage units typically with low concrete walls and a viny l top.

EPA's Information Gathering Authority Under Section 114 of the Clean Air Act
Under Section 114 of the Act (42 U.S.C. 7414), Congress has given the U.S. Environmental Protection Agency broad authority to secure information needed for the purpose of (i) developing or assisting in the development of any implementation plan under Sect ion 110 or 111(d), any standard of performance under Section 111, or any emission standard under Section 112; (ii) determining whether any person is in violation of any such standard of any requirement of such a plan; or (iii) carrying out any prov ision of this Act. Among other things, Section 114 authorizes EPA to make ins pections, conduct tests, examine records, and require owners or operators of emission sources to submit information reasonably required for the purpose of developing such standards. In addition, the EPA Office of General Counsel has interpreted Section 114 to include authority to photograph or require submission of photographs of pertinent equipment, emissions, or both.
Under Section 114, EPA is empowered to obtain info rmation described by that section even if you consider it to be confidential. You may, however, request that EPA treat such information as confidential. Information obtained under Section 114 and covered by such a request will ordinarily be released to the public only if EPA determines that the information is not entitled to confidential treatment. 1 Procedures to be used for making confidentiality determinations, substantive criteria to be used in such determinations, and special rules governing information obtained under Section 114 are set forth in 40 CFR Part 2 published in the Federal Register on September 1, 1976 (40 FR 36902).
Pursuant to § 2.204(a) of EPA's Freedom of Information Act (FOIA) regulation, in the event a request is received, or it is determined that a request is likely to be received, or EPA desires to determine whether business information in its possession is entitled to confidential treatment even though no request for release of the information has been received, please be advised that EPA will seek, at that time, the following information to support your claim as required by § 2.204(e)(4) of EPA's FOIA regulations:
1. Measures taken by your company to guard against undesired disclosure of the information to others;
2. The extent to which the information has been disclosed to others, and the precautions taken in connection therewith;
3. Pertinent confidentiality determinations, if any, by EPA or other Federal agencies, and a copy of any such determinations, or reference to it, if available; and
4. Whether your company asserts that disclosure of the information would be likely to result in substantial harmful effects on the business' competitive position, and if so, what those harmful effects would be, why they should be viewed as substantial, and an explanation of the causal relationship between disclosure and such harmful effects.

1 Section 114 requires public availability of all emission da ta and authorizes disclosure of confidential information in certain circumstances. See 40 FR 36902 - 36912 (September 1, 1976).

# Introduction

Pace Analytical Services, Inc. personnel conducted particulate and opacity emissions compliance testing on the East Baghouse St ack and the West Baghouse Stack at the ADM-Benson Quinn facility located in Roge rs, North Dakota. Opactiy observations were also recorded for Conveyor Bins 104, 19 & 20, and 21. Mike Walter, Adam Birr and Matt McDermott performed on-site testing activities. Terry Borgerding provided administrative project management. Cr is Breidenbach with ADM-Benson Quinn coordinated plant activities during test ing. Jeff Cleland with ADM prepared a comprehensive test protocol that was subm itted to the North Da kota Department of
Health. On-site activities consis ted of the followin g measurements:

- Particulate, three independent 84 minute samplings. - Opacity, three independent one-hour observation periods.

- Volumetric airflow, measurements collect ed in conjunction with isokinetic testing.

The project objectives were to quantify part iculate and opacity emission constituents and compare them to applicable air emissions regulations stipulated by North Dakota Department of Health and the facility permit. These measurements were performed at 90+% capacity. Quality protocols comp ly with regulatory compliance testing requirements.

Subsequent sections summarize the test resu lts and provide descriptions of the process and test methods. Supporting information and raw data are in the appendices.

# Results Summary

Results of particulate determi nations are summarized in Tabl e 1 and 2. The particulate emission rate from the East Baghouse Stack averaged 0.053 LB/HR at 0.0004 GR/DSCF. The particulate emission rate from the West B aghouse Stack averaged
0.059 LB/HR at 0.0004 GR/DSCF. The particulate emission limit for this source is 0.01 GR/DSCF. Subsequent tables provide expanded detail of the testing results.

Results of opacity observations are detailed in Tables 9-13 . All of the observations on each source were zero percent.

The data in this report are indicative of emission char acteristics of the measured sources for process conditions at the time of the test. Representations to other sources and test conditions are beyond the scope of this report.

# Process Description

ADM – Benson Quinn operates a grain handling facility lo cated in Rogers, North Dakota. The theoretical capacity of t he West Grain Dump handing processes is 160,000 bushels per 8 hours and 80,000 bushels per 8 hours for the East Grain Dump for a total capacity of 240,000 bushels per 8 hours. The through-put during testing on the East Baghouse (5/6/08) was 144,832 from the West Grain Dump and 71,815 from the East Grain Dump for a total of 216,647 bushels. The through- put during testing on the West Baghouse (5/7/08) was 145,810 from the West Grain Dump and 70,925 from the East Grain Dump for a total of 216,735 bu shels. The pressure drop across the West Baghouse remained constant at 3 inches WC. The pressure drop across the East Baghouse remained constant at 1.2 inches WC.

# Test Procedures

EPA Method 1 specifies test location acceptability criteria and defines the minimum number of traverse points fo r representative sampling. Linear measurements from upstream and downstream flow disturbances and the duct equival ent diameter are compared and the distances relat ed to number of diameters. A flow disturbance can be defined as anything that changes or upsets the direction of fl ow within the duct including bends, dampers, fans, shape or size transiti ons and open flames. Method 1 stipulates that test ports should be located at least eight diameters downst ream and two diameters upstream of any flow disturbanc e. The minimum acceptable criteria are two diameters downstream and 0.5 diameters ups tream of flow disturbances. The test location must also be free of cyclonic or multidirectiona l flow. Once the distances have been determined, the values are used to select the minimum number of traverse points for representative sampling. Shorter distances r equire a greater number of traverse points. The test site configuration is show n in Figure 1 and 2 and has the following characteristics:

Test Location: East BH Stack West BH Stack Duct Cross-sectional Dimension: 28” 30” Distance From Upstream Disturbance: 55“ 60” Number of Duct Diameters: 2 2 Distance To Downstream Disturbance: 23” 36 “ Number of Duct Diameters: 0.5 0.5 Cyclonic or Multidirectional Fl ow: No, verified No, verified Number of Traverse Points: 24 24

EPA Method 2 defines procedures used to measure li near velocity and volumetric flow rate of a confined gas stream. Using tr averse points determined by EPA Method 1, multiple differential pressure measurem ents (pitot impact opening versus static pressure) are made using a pitot tube and diffe rential pressure gauge. The individual measurements are averaged a nd combined with the gas density to calculate the average gas velocity. The velocity and duct cross-sectional area ar e used to calculate the volumetric flow rate. The volumetric flow rate is expre ssed as actual cubic feet per minute (ACFM), standard cubic feet per minut e (SCFM), and dry standard cubic feet per minute (DSCFM). The technician maintains comprehensive test records on handwritten field data sheets. Details of the equipment used to measure gas velocity include:
Pitot Tube: S-Type Differential Pressure Gauge: Oil Manometer Temperature Device: Type K Thermocouple Barometer Type: Electronic Digital Barometer Gas Density Determination: EPA Method 3 Gas Moisture Determination: EPA Method 4

### EPA Method 3 allows the use of publis hed or ambient gas concentrations in cases where the source gas is free of combustion components. For this test, ambient gas concentrations are used to calculate gas molecular weight.

EPA Method 4 defines procedures to measure the moisture content of emissions gas streams from stationary sources. The moisture content of the gas stream is determined in conjunction with the isokinetic samplin g train described below. Collected water condensate is measured from the back half of the isokinetic train. Method 4 equations convert the condensed liquid volume to a gas volume. The water vapor volume compared with the dry standard gas volume collected through the isokinetic train determines the moisture content of the emissions gas stream and is reported in percent by volume.
Probe Material: Borosilicate glass Filter Media: Quartz fiber , >99.95% efficient at 0.3 μm Impinger Train Material : Borosilicate glass Desiccant: Drierite Condensate Measur e: Graduated Cylinder Desiccant Measure: Electronic balance

EPA Method 5 defines procedures to measure parti culate emissions from stationary sources. Using traverse points dete rmined from EPA Method 1 and incorporating procedures from EPA Methods 2, 3, and 4, a sa mple gas stream is isokinetically drawn from the emission stream. To attain isokinetic sampling, a sampling nozzle of a known diameter points directly into the oncoming ga s steam. The train oper ator calculates and adjusts the gas sampling rate to match th e gas velocity entering the nozzle with the emission stream velocity. Isokinetic sa mpling eliminates biases from differing particulate aerodynamic characte ristics. The particulate dr y fraction collects in the sampling probe and on a quartz or glass-fiber filter. The pr obe and filter components of the sampling train are unheated per sub part DD. The filt ered sample gas stream passes through a series of impingers to condense water vapor and collect gaseous constituents. The first two impingers init ially contain deionized water and a third impinger is empty. A desi ccant packed drying column follows the impingers to quantitatively collect the remaining moisture. An ice bath maintains the impinger train temperature (outlet) at 68°F or less. The impinger content s can be discarded or saved for additional analyses. Sample recovery and train clean up are performed after each run using procedures to ensure sample int egrity and quantitative recovery. The train operator maintains comprehensive test re cords on handwritten field data sheets. Details of particulate testing are outlined below:

Nozzle/Probe Material: Stainl ess steel and borosilicate glass Filter Holder Material : Borosilicate glass Filter Media: Glass fiber , >99.95% efficient at 0.3 μm Impinger Train Material : Borosilicate glass

### Impinger Reagents: Deionized water Recovery Reagents: Acetone Deionized water Control Train: Gas meter, orif ice, differential pressure gauges, pump, valves, temperature monitors and controllers Analytical Techniques: Gravimetric

EPA Method 9 defines procedures to ev aluate the opacity of the plume emitted from a source stack. An independently certified visible emissions observer visually estimates the opacity of the non-moisture plume from the source. The observer positions themselves with the sun (or other light sour ce) at their back and perpendicular to the plume when directly facing the emission point. The observer must also ensure a clear and contrasting background behind the plume. The certified observer then estimates (based on certificati on trials) the percentage of the ba ckground blocked by the source plume (plume opacity) in increments of 5%. Observed opacity readings are recorded at 15-second intervals throughout the run. Tabulated re sults include run average and successive six-minute averages. The spreadsheet software also searches the data set for a group of 24 consecutive readings that yield the highest possible six-minute average. Details of the opacit y evaluation are outlined below.

Evaluation Period: One hour Observation Frequency: 15 Seconds No. of Observations: 240 No. of Six-minutes Averages: 10 Observer Certifications: Semi-annual
