SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Grain Elevators (40 CFR Part 60, Subpart DD) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Grain Elevators (40 CFR Part 60, Subpart DD) (Renewal), 

EPA ICR Number 1130.11, OMB Control Number 2060-0082. 

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for Grain Elevators (40 CFR Part 60, 

Subpart DD) were proposed on January 18, 1977, promulgated on August 3, 1978, and amended 

on October 17, 2000 (65 FR 61759). These regulations apply to the following facilities in grain 

elevators: each truck unloading station, truck loading station, railcar unloading station, railcar 

loading station, grain dryer, and all grain handling operations commencing construction, 

modification or reconstruction after August 3, 1978. This information is being collected to assure 

compliance with 40 CFR Part 60, Subpart DD. On July 9, 2014, EPA proposed to amend the 

NSPS for Grain Elevators; the proposed changes will be addressed in a new subpart DDa and 

covered under a separate ICR.

In general, all NSPS standards require initial notifications, performance tests, and 

periodic reports by the owners/operators of the affected facilities. They are also required to 

maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the 

operation of an affected facility, or any period during which the monitoring system is 

inoperative. These notifications, reports, and records are essential in determining compliance, 

and are required of all affected facilities subject to NSPS.

Any owner/operator subject to the provisions of this part shall maintain a file of these 

measurements, and retain the file for at least two years following the date of such measurements, 

maintenance reports, and records. All reports are sent to the delegated state or local authority. 

In the event that there is no such delegated authority, the reports are sent directly to the U.S.

Environmental Protection Agency (EPA) regional office.

Based on our consultations with industry representatives, there is an average of one 

affected facility at each plant site and that each plant site has only one respondent (i.e., the 

owner/operator of the plant site).

Over the next three years, approximately 200 respondents per year will be subject to 

these standards, and no additional respondents per year will become subject to these same

standard. This estimate is based on the Agency’s estimate from a previous ICR renewal. 

The Office of Management and Budget (OMB) approved the currently active Information 

Collection Request (ICR) with the following Terms of Clearance (TOC):
2

Before this ICR is renewed, the agency should update the universe and 

burden estimates.

The Agency addressed the TOC by consulting with industry trade associations to verify

the current number of facilities and industry growth rate. In addition, the ICR burden estimates 

has been updated to reflect the latest labor rates. 

All of the grain elevators in the United States are owned and operated by the grain 

elevators industry (the “Affected Public”), which is a privately-owned, for-profit business

industry. None of these facilities in the United States are owned by either state, local, tribal or the 

Federal government. The “burden” to the Affected Public is listed below in Table 1: Annual 

Respondent Burden and Cost – NSPS for Grain Elevators (40 CFR Part 60, Subpart DD) 

(Renewal). The Federal government’s “burden” associated with the review of reports submitted 

by the respondent is shown below in Table 2: Average Annual EPA Burden and Cost– NSPS for 

Grain Elevators (40 CFR Part 60, Subpart DD) (Renewal).

2. Need for and Use of the Collection

2(a) Need/Authority for the Collection

The EPA is charged under Section 111 of the Clean Air Act (CAA), as amended, to 

establish standards of performance for new stationary sources that reflect: 

. . . application of the best technological system of continuous 

emissions reduction which (taking into consideration the cost of 

achieving such emissions reduction, or any non-air quality health 

and environmental impact and energy requirements) the 

Administrator determines has been adequately demonstrated.

Section 111(a)(l).

The Agency refers to this charge as selecting the best demonstrated technology (BDT). Section 

111 also requires that the Administrator review and, if appropriate, revise such standards every

eight years. 

In addition, section 114(a) states that the Administrator may require any owner/operator 

subject to any requirement of this Act to: 

(A) Establish and maintain such records; (B) make such reports; 

(C) install, use, and maintain such monitoring equipment, and use 

such audit procedures, or methods; (D) sample such emissions (in 

accordance with such procedures or methods, at such locations, at 

such intervals, during such periods, and in such manner as the 

Administrator shall prescribe); (E) keep records on control 

equipment parameters, production variables or other indirect data 
3

when direct monitoring of emissions is impractical; (F) submit

compliance certifications in accordance with Section 114(a)(3); 

and (G) provide such other information as the Administrator may

reasonably require.

In the Administrator's judgment, particulate matter emissions from grain elevators 

facilities either cause or contribute to air pollution that may reasonably be anticipated to 

endanger public health and/or welfare. Therefore, the NSPS were promulgated for this source 

category at 40 CFR Part 60, Subpart DD.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standards ensure compliance with 

the applicable regulations which were promulgated in accordance with the Clean Air Act. The 

collected information is also used for targeting inspections and as evidence in legal proceedings.

Performance tests are required in order to determine an affected facility’s initial 

capability to comply with the emission standard. Continuous emission monitors are used to 

ensure compliance with the standard at all times. During the performance test a record of the 

operating parameters under which compliance was achieved may be recorded and used to 

determine compliance in place of a continuous emission monitor.

The notifications required in the standard are used to inform the Agency or delegated 

authority when a source becomes subject to the requirements of the regulations. The reviewing 

authority may then inspect the source to check if the pollution control devices are properly 

installed and operated, that leaks are being detected and repaired, and the standard is being met.

The performance test may also be observed.

The required annual summary reports are used to determine periods of excess emissions, 

identify problems at the facility, verify operation/maintenance procedures and for compliance 

determinations.

3. Non-duplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under 40 CFR Part 60, Subpart 

DD.

3(a) Non-duplication

If the subject standards have not been delegated, the information is sent directly to the 

appropriate EPA regional office. Otherwise, the information is sent directly to the delegated state 

or local agency. If a state or local agency has adopted its own similar standards to implement the 

Federal standards, a copy of the report submitted to the state or local agency can be sent to the 

Administrator in lieu of the report required by the Federal standards. Therefore, duplication does 

not exist.

3(b) Public Notice Required Prior to ICR Submission to OMB

An announcement of a public comment period for the renewal of this ICR was published 

in the Federal Register (80 FR 32120) on June 5, 2015. No comments were received on the 

burden published in the Federal Register.

3(c) Consultations

The Agency has consulted industry experts and internal data sources to project the 

number of affected facilities and industry growth over the next three years. The primary source 

of information as reported by industry, in compliance with the recordkeeping and reporting 

provisions in the standard, is the Integrated Compliance Information System (ICIS). ICIS is 

EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial 

and government-owned facilities. The growth rate for the industry is based on our consultations 

with the Agency’s internal industry experts. 

Industry trade associations and other interested parties were provided an opportunity to 

comment on the burden associated with the standard as it was being developed and the standard 

has been previously reviewed to determine the minimum information needed for compliance 

purposes. In developing this ICR, we contacted both the National Grain and Feed Association 

(NGFA), at (202)289-0873; and the Grain Elevator and Processing Society, at (763) 999-4300. 

NGFA responded in September 2015 on behalf of a coalition of national trade associations for 

which it serves as chair, i.e., the NSPS Subpart DD Coalition, which includes the Corn Refiners 

Association, National Council of Farmer Cooperatives, National Grain and Feed Association, 

National Oilseed Processors Association, North American Millers’ Association and USA Rice 

Federation. 

The Coalition agreed with the Agency’s estimate of zero growth over the three-year 

period of this ICR, and stated that it has no information to confirm the estimate of 200 

respondents. Further, the Coalition noted that the current ICR indicates an “annual summary

report” is required under 40 CFR Section 60.7(d), however, Subpart DD itself does not actually

require continuous monitoring. In this ICR, we have removed the “annual summary report” line 

item to accurately reflect the regulatory requirement. 

It is our policy to respond after a thorough review of comments received since the last 

ICR renewal as well as those submitted in response to the first Federal Register notice.

3(d) Effects of Less Frequent Collection

Less frequent information collection would decrease the margin of assurance that 

facilities are continuing to meet the standards. Requirements for information gathering and 

recordkeeping are useful techniques to ensure that good operation and maintenance practices 

are applied and emission limitations are met. If the information required by these standards was 

collected less frequently, the proper operation and maintenance of control equipment and the 
5

possibility of detecting violations would be less likely.

3(e) General Guidelines

These reporting or recordkeeping requirements do not violate any of the regulations 

promulgated by OMB under 5 CFR Part 1320, Section 1320.5.

3(f) Confidentiality

Any information submitted to the Agency for which a claim of confidentiality is made 

will be safeguarded according to the Agency policies set forth in Title 40, chapter 1, part 2, 

subpart B - Confidentiality of Business Information (CBI) (see 40 CFR 2; 41 FR 36902, 

September 1, 1976; amended by 43 FR 40000, September 8, 1978; 43 FR 42251, September 20, 

1978; 44 FR 17674, March 23, 1979).

3(g) Sensitive Questions

The reporting or recordkeeping requirements in the standard do not include sensitive 

questions.

4. The Respondents and the Information Requested

4(a) Respondents/SIC Codes

The respondents to the recordkeeping and reporting requirements are grain elevators. The 

United States Standard Industrial Classification (SIC) codes for the respondents affected by the 

standards, and the corresponding North American Industry Classification System (NAICS) 

codes, are listed below. 

Standard (40 CFR, Part 60, Subpart DD) SIC Codes NAICS Codes

4(b) Information Requested

(i) Data Items
6

In this ICR, all the data that is recorded or reported is required by the NSPS for Grain 

Elevators (40 CFR Part 60, Subpart DD).

A source must make the following reports:

Notifications

Notification of construction or reconstruction 60.7(a)(1)

Notification of actual startup 60.7(a)(3)

Notification of initial performance test 60.8(d)

Initial performance test results 60.8(a)

Repeat performance tests 60.7(a)(4)

A source must keep the following records:

Recordkeeping

Startup, shutdown, or malfunction period where the continuous 

monitoring system is inoperative 60.7(b)

Records are required to be retained for two years and kept onsite 60.7(f)

Electronic Reporting

Some of the respondents are using monitoring equipment that automatically records 

parameter data. Although personnel at the affected facility must still evaluate the data, internal 

automation has significantly reduced the burden associated with monitoring and recordkeeping at 

a plant site.

(ii) Respondent Activities

Respondent Activities

Familiarization with the regulatory requirements.

Perform initial performance test, Reference Method 2, 5, 7, and 9, and repeat performance test 

if necessary.

Write the notifications and reports listed above.

Enter information required to be recorded above.

Submit the required reports developing, acquiring, installing, and utilizing technology and 
7

Respondent Activities

systems for the purpose of collecting, validating, and verifying information.

Develop, acquire, install, and utilize technology and systems for the purpose of processing and 

maintaining information.

Develop, acquire, install, and utilize technology and systems for the purpose of disclosing and 

providing information.

Adjust the existing ways to comply with any previously applicable instructions and 

requirements.

Train personnel to be able to respond to a collection of information.

Transmit, or otherwise disclose the information.

Currently, sources are using monitoring equipment that provides parameter data in an 

automated way (e.g., continuous parameter monitoring system). Although personnel at the 

source still need to evaluate the data, this type of monitoring equipment has significantly reduced 

the burden associated with monitoring and recordkeeping.

5. The Information Collected: Agency Activities, Collection Methodology, and Information 

Management

5(a) Agency Activities

EPA conducts the following activities in connection with the acquisition, analysis, 

storage, and distribution of the required information.

Agency Activities

Observe initial performance tests and repeat performance tests if necessary.

Review notifications and reports, including performance test reports, and excess emissions 

reports, required to be submitted by industry.

Audit facility records.

Input, analyze, and maintain data in the Enforcement and Compliance History Online (ECHO) 

and ICIS. 

5(b) Collection Methodology and Management

Following notification of startup, the reviewing authority could inspect the source to 

determine whether the pollution control devices are properly installed and operated. Performance 
8

test reports are used by the Agency to discern a source’s initial capability to comply with the 

emission standard and note the operating conditions under which compliance was achieved. Data 

and records maintained by the respondents are tabulated and published for use in compliance and 

enforcement programs. The semiannual reports are used for problem identification, as a check on 

source operation and maintenance, and for compliance determinations.

Information contained in the reports is reported by state and local governments in the 

ICIS Air database, which is operated and maintained by EPA's Office of Compliance. ICIS is 

EPA’s database for the collection, maintenance, and retrieval of compliance data for industrial 

and government-owned facilities. EPA uses ICIS for tracking air pollution compliance and 

enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters.

EPA and its delegated Authorities can edit, store, retrieve and analyze the data.

The records required by this regulation must be retained by the owner/operator for two

years.

5(c) Small Entity Flexibility

A majority of the respondents are large entities (i.e., large businesses). However, the 

impact on small entities (i.e., small businesses) was taken into consideration during the 

development of the regulation. Due to technical considerations involving the process operations 

and the types of control equipment employed, the recordkeeping and reporting requirements are 

the same for both small and large entities. The Agency considers these to be the minimum 

requirements needed to ensure compliance and, therefore, cannot reduce them further for small 

entities. To the extent that larger businesses can use economies of scale to reduce their burden, 

the overall burden will be reduced.

5(d) Collection Schedule

The specific frequency for each information collection activity within this request is 

shown below in Table 1: Annual Respondent Burden and Cost –NSPS for Grain Elevators (40 

CFR Part 60, Subpart DD) (Renewal).

6. Estimating the Burden and Cost of the Collection

Table 1 documents the computation of individual burdens for the recordkeeping and 

reporting requirements applicable to the industry for the subpart included in this ICR. The 

individual burdens are expressed under standardized headings believed to be consistent with the 

concept of burden under the Paperwork Reduction Act. Where appropriate, specific tasks and 

major assumptions have been identified. Responses to this information collection are mandatory.

The Agency may not conduct or sponsor, and a person is not required to respond to, a 

collection of information unless it displays a currently valid OMB Control Number.
9

6(a) Estimating Respondent Burden

The average annual burden to industry over the next three years from these recordkeeping and reporting requirements is estimated to be 460 hours (Total Labor Hours from Table 

1 below). These hours are based on Agency studies and background documents from the 

development of the regulation, Agency knowledge and experience with the NSPS program, the 

previously approved ICR, and any comments received.

6(b) Estimating Respondent Costs

(i) Estimating Labor Costs

This ICR uses the following labor rates: 

Managerial $129.93 ($61.87+ 110%)

Technical $103.97 ($49.51 + 110%)

Clerical $51.79 ($24.66 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 

2014, “Table 2. Civilian Workers, by occupational and industry group.” The rates are from 

column 1, “Total compensation.” The rates have been increased by 110 percent to account for 

the benefit packages available to those employed by private industry.

(ii) Estimating Capital/Startup and Operation and Maintenance Costs

The only costs to the regulated industry resulting from information collection activities 

required by the subject standard are labor costs. There are neither capital/startup nor operation 

and maintenance costs.

(iii) Capital/Startup vs. Operation and Maintenance (O&M) Costs

The only type of industry costs associated with the information collection activity in the 

regulations are labor costs. There are no capital/startup or operation and maintenance costs.

6(c) Estimating Agency Burden and Cost

The only costs to the Agency are those costs associated with analysis of the reported 

information. EPA's overall compliance and enforcement program includes activities such as 

the examination of records maintained by the respondents, periodic inspection of sources of 

emissions, and the publication and distribution of collected information. 

The average annual Agency cost during the three years of the ICR is estimated to be $0.

This cost is based on the average hourly labor rate as follows:

Managerial $62.90 (GS-13, Step 5, $39.31 + 60%) 
10

Technical $46.67 (GS-12, Step 1, $29.17 + 60%)

Clerical $25.25 (GS-6, Step 3, $15.78 + 60%)

These rates are from the Office of Personnel Management (OPM), 2014 General Schedule,

which excludes locality rates of pay. The rates have been increased by 60 percent to account for 

the benefit packages available to government employees. Details upon which this estimate is 

based appear below in Table 2: Average Annual EPA Burden and Cost – NSPS for Grain 

Elevators (40 CFR Part 60, Subpart DD) (Renewal).

6(d) Estimating the Respondent Universe and Total Burden and Costs

Based on our research for this ICR, on average over the next three years, approximately

200 existing respondents will be subject to these standards. It is estimated that no additional 

respondents per year will become subject to these same standards. The overall average number 

of respondents, as shown in the table below, is 200 per year. 

The number of respondents is calculated using the following table that addresses the three 

years covered by this ICR:

The number of Total Annual Responses is 200.

The total annual labor costs are $46,000. Details regarding these estimates may be found 

below in Table 1: Annual Respondent Burden and Cost – NSPS for Grain Elevators (40 CFR 

Part 60, Subpart DD) (Renewal).

6(e) Bottom Line Burden Hours and Cost Tables

The detailed bottom line burden hours and cost calculations for the respondents and the 

Agency are shown in Tables 1 and 2 below, respectively, and summarized below.

(i) Respondent Tally

The total annual labor hours are 460 hours. Details regarding these estimates may be 

found below in Table 1. Annual Respondent Burden and Cost – NSPS for Grain Elevators (40 

CFR Part 60, Subpart DD) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical 

tasks because the typical tasks for managers are to review and approve reports. Clerical burdens 

are assumed to take 10% of the time required for technical tasks because the typical duties of 

clerical staff are to proofread the reports, make copies and maintain records.

Furthermore, the annual public reporting and recordkeeping burden for this collection of 

information is estimated to average 2 hours per response.

There are no capital/startup or operation and maintenance costs.

(ii) The Agency Tally

The average annual Agency burden and cost over next three years is estimated to be 0
12

labor hours at a cost of $0. See Table 2: Average Annual EPA Burden and Cost – NSPS for 

Grain Elevators (40 CFR Part 60, Subpart DD) (Renewal).

We assume that burdens for managerial tasks take 5% of the time required for technical 

tasks because the typical tasks for managers are to review and approve reports. Clerical burdens 

are assumed to take 10% of the time required for technical tasks because the typical duties of 

clerical staff are to proofread the reports, make copies and maintain records.

6(f) Reasons for Change in Burden

There is a decrease in the respondent and Agency burden in this ICR compared to the 

previous ICR. This is not due to program changes. The burden and cost decrease because we 

corrected the burden estimates by removing the annual summary report line item to more 

accurately reflect the Subpart DD regulatory requirements. The current Subpart DD NSPS does 

not impose any ongoing monitoring or reporting requirement. 

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information 

is estimated to average 2 hours per response. Burden means the total time, effort, or financial 

resources expended by persons to generate, maintain, retain, or disclose or provide information 

to or for a Federal agency. This includes the time needed to review instructions; develop, 

acquire, install, and utilize technology and systems for the purposes of collecting, validating, and 

verifying information, processing and maintaining information, and disclosing and providing 

information; adjust the existing ways to comply with any previously applicable instructions and 

requirements; train personnel to be able to respond to a collection of information; search data 

sources; complete and review the collection of information; and transmit or otherwise disclose 

the information.

An agency may not conduct or sponsor, and a person is not required to respond to, a 

collection of information unless it displays a valid OMB Control Number. The OMB Control 

Numbers for EPA regulations are listed at 40 CFR Part 9 and 48 CFR Chapter 15.

To comment on the Agency's need for this information, the accuracy of the provided 

burden estimates, and any suggested methods for minimizing respondent burden, including the 

use of automated collection techniques, EPA has established a public docket for this ICR under 

Docket ID Number EPA-HQ-OECA-2011-0239. An electronic version of the public docket is

Assumptions:

a We have assumed that there are approximately 200 respondents, with no additional new or reconstructed sources becoming subject to the rule over the next three 

years. 

b

This ICR uses the following labor rates: $129.93 per hour for Executive, Administrative, and Managerial labor; $103.97 per hour for Technical labor, and $51.79 per 

hour for Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2014 “Table 2. Civilian workers, by occupational 

and industry group.” The rates are from column 1, “Total compensation.” The rates have been increased by 110 percent to account for the benefit packages available to 

those employed by private industry.

c We have assumed that it will take twenty-eight hours for each new respondent to perform the initial performance test.

d We have assumed that 20 percent of respondents would repeat performance test due to failure.

e We have assumed that all respondents will each take eight hours to write the annual summary report.
16

f We have assumed that each respondent will take one hour to record information on startup, shutdown, malfunction.

g Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
