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 capacity, 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 information 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 the 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 responses 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 paragraphs 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 temporary 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 obtain 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 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 vinyl 

top. The use of the terms “permanent storage” and “temporary storage” is strictly to reflect the current 
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 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 vinyl top. The use of the terms “permanent storage” 

and “temporary storage” is strictly to reflect the current terminologies used in industry as defined 

by the U.S. Department of Agriculture (USDA) and in no way represents any EPA decision as to 

how these units will be treated in any subsequent action. See definitions section for a list of 

terms used in this survey. 

In addition to the items listed in the survey forms that follow this introduction, we are also 

requesting copies of the following information to the extent it relates to grain elevators or 

portions of processing plants that consist of grain elevators: 

1. Your current air quality operating permit, if you have one. 

2. Copies of the most recent results from PM/PM10 emissions testing conducted at your 

facility within the last 3 years, including but not limited to, opacity measurements and 

stack testing. No new testing is required for this survey.

ENCLOSURE 2 

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 Section 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 provision of this Act. Among 

other things, Section 114 authorizes EPA to make inspections, 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 information 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. 

 

 1Section 114 requires public availability of all emission data and authorizes disclosure of confidential information in 

certain circumstances. See 40 FR 36902 - 36912 (September 1, 1976).
