### 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. 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.

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
