SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Nonmetallic Mineral Processing (40 CFR, Part 60, Subpart OOO) (Renewal)

1. Identification of the Information Collection

1(a) Title and Number of the Information Collection

NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal), 

EPA ICR Number 1084.12, OMB Control Number 2060-0050.

1(b) Short Characterization

The New Source Performance Standards (NSPS) for Nonmetallic Mineral Processing (40 

CFR part 60, subpart OOO) were proposed on August 31, 1983, promulgated on August 1, 1985, 

and most recently amended on April 28, 2009. These regulations apply to the following affected 

facilities in fixed or portable nonmetallic mineral processing plants: each crusher, grinding mill, 

screening operation, bucket elevator, belt conveyor, bagging operation, storage bin, and enclosed 

truck or railcar loading station, which commenced construction, modification or reconstruction 

after August 31, 1983. Also, crushers and grinding mills at hot mix asphalt facilities that reduce 

the size of nonmetallic minerals embedded in recycled asphalt pavement and subsequent affected 

facilities up to, but not including, the first storage silo or bin are subject to the provisions of the 

subpart. 

The provisions of subpart OOO do not apply to the following operations: facilities 

located in underground mines; wet material processing operations; and plants without crushers 

or grinding mills. An affected facility that is subject to the provisions of either subparts F or I,

or that follows in the process any facility subject to the provisions of subparts F or I of this part,

is not subject to the provisions of this part. In addition, the following plants are not subject to 

subpart OOO: fixed sand and gravel plants and crushed stone plants with capacities of 23 

megagrams per hour (25 tons per hour) or less; portable sand and gravel plants and crushed stone 

plants with capacities of 136 megagrams per hour (150 tons per hour) or less; common clay

plants and pumice plants with capacities of 9 megagrams per hour (10 tons per hour) or less. 

This information is being collected to assure compliance with 40 CFR part 60, subpart OOO.

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 or 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. 
2

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.

Over the next three years, an average of 4,697 respondents per year will be subject to the 

standard, and 66.4 additional respondents per year will become subject to the standard.

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

Collection Request (ICR) without any “Terms of Clearance.”

The respondents to this ICR (the “Affected Public) are publicly owned and operated by 

fixed or portable nonmetallic mineral processing plants. None of the facilities are owned by 

either state, local and tribal agencies or the Federal government. The burden to respondents is 

calculated below in Table 1: Annual Respondent Burden and Cost − NSPS for Nonmetallic 

Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal). The burden to the “Federal 

Government” burden is attributed entirely to work performed by Federal employees or 

government contractors. This burden is calculated below in Table 2: Average Annual EPA

Burden and Cost − NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) 

(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

four years.

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

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 
3

equipment parameters, production variables or other indirect data 

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 emissions from nonmetallic mineral 

processing plants (NMPP) cause or contribute to air pollution that may reasonably be anticipated 

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

category at 40 CFR part 60, subpart OOO.

2(b) Practical Utility/Users of the Data

The recordkeeping and reporting requirements in the standards ensure compliance with 

the applicable regulations which where 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 standards. Continuous emission monitors are used to

ensure compliance with the standards at all times. 

The notifications required in the standards 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 and the standards are being met. The performance test may also be 

observed.

The required semiannual compliance status 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 

OOO. 

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 their 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, 

no duplication exists.
4

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 (76 FR 26900) on May 9, 2011. 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 Online Tracking Information System (OTIS), which is operated 

and maintained by EPA’s Office of Compliance. OTIS is EPA’s database for the collection, 

maintenance, and retrieval of all compliance data. 

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. In developing 

this ICR, we contacted: 1) the National Stone, Sand, and Gravel Association (NSSGA), at (703) 

525-8788; 2) the Industrial Minerals Association - North America (IMA-NA), at (240) 457-

0200; and 3) the Georgia Mining Association (GMA), at (478) 757-1211.

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 

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(b) Information Requested

(i) Data Items 

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

Mineral Processing (40 CFR Part 60, Subpart OOO).

A source must make the following reports:

Notifications

Notification of actual startup. 60.7(a)(3), 60.676(i)

Physical or operational change. 60.7(a)(4)

Notification of initial performance test. 60.8(d), 60.672

Reports

Initial performance test results. 60.8(a), 60.676(f)

Repeat performance test results. 60.8(a), 60.11, 60.675

A source must keep the following records:

Recordkeeping

Startups, shutdowns, malfunctions, periods where the continuous 

monitoring system is inoperative.

60.7(b)

Records are required to be retained for two (2) years and kept onsite. 60.7(f)

Records of ongoing monitoring.

60.7(f), 60.674(b), 

60.674(c)

Records of replacement activities 60.670(d), 60.676
7

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.

Also, regulatory agencies, in cooperation with the respondents, continue to create 

reporting systems to transmit data electronically. However, electronic reporting systems are not 

widely used. At this time, it is estimated that approximately 10 percent of the respondents use 

electronic reporting.

(ii) Respondent Activities. 

Respondent Activities

Read instructions.

Perform initial performance test using appropriate Reference Method, and repeat performance 

tests 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 

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 Online Tracking Information System (OTIS).

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

with the emission standard. 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 entered into OTIS, which is operated and 

maintained by EPA's Office of Compliance. OTIS is EPA’s database for the collection, 

maintenance, and retrieval of compliance data for approximately 125,000 industrial and 

government-owned facilities. EPA uses OTIS 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 or operator for two 

years.

5(c) Small Entity Flexibility

The majority of respondents are estimated to be small entities. The impact on small 

entities (i.e., small businesses) was taken into consideration during the development of the 

regulation by exempting wet material processing operations, simplifying certain notification 

requirements, and selecting relatively low-cost repeat testing and monitoring provisions. In 

addition, certain plants operating at small capacities were exempted from subpart OOO due to 

economic considerations when the standards were originally developed. Due to technical 

considerations involving the process operations and the types of control equipment employed, 
9

the recordkeeping and reporting requirements are the same for both small and large entities. 

The Agency considers these requirements the minimum needed to ensure compliance and, 

therefore, cannot reduce them further for small entities. 

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 Nonmetallic Mineral 

Processing (40 CFR Part 60, Subpart OOO) (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. Wherever 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.

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 12,374 (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 $121.42 ($57.82 + 110%)

Technical $99.14 ($47.21 + 110%)

Clerical $49.81 ($23.27 + 110%)

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

September 2011, “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.
10

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

The type of industry costs associated with the information collection activities in the 

subject standards are both labor costs which are addressed elsewhere in this ICR and the costs 

associated with continuous monitoring. The capital/startup costs are one -time costs when a 

facility becomes subject to the regulation. The annual operation and maintenance costs are the 

ongoing costs to maintain the monitors and other costs such as photocopying and postage.

a

The total costs for performance testing were calculated for each industry sector covered by subpart OOO. A testing 

cost of $7,000 for Method 5 tests and $216.67 for a 30-minute Method 9 tests was used. It was assumed there are 22 

emission points for each plant in the crushed/broken stone and sand/gravel sectors and 9 emission points for each 

plant in other sectors.

b Growth in each of the NMPP sectors was estimated using model plants and recent (e.g., 2005/2006) production 

data available from the U.S. Geological Survey (USGS) and model plant parameters used in development of the 

original promulgated NSPS. It is estimated that, of the 66.4 new respondents per year, 60.9 will be in the 

crushed/broken stone and sand/gravel sectors and 5.5 will be in other sectors. 

c These are annualized costs for all new respondents. The capital cost associated with testing was annualized 

assuming a 7 percent interest rate and 5-year life (i.e., capital recovery factor [CRF] of 0.2439). The annualized 

capital cost for file cabinets was calculated using a 7 percent interest rate and a 15-year life (i.e., CRF of 0.1098).

The total cost for performance testing is $626,767 per year, and the total capital cost for filing cabinets was 

estimated at $15,604. Over the 3-year period, performance test costs are $1.0 million and $872,000 for Method 5 

and Method 9 respectively. 

The total capital/startup costs for this ICR are $154,577 per year (rounded). This is the 

total of column D in the above table.

The total operation and maintenance (O&M) costs for this ICR are zero.

The average annual cost for capital startup and operation and maintenance costs to 

industry over the next three years of the ICR is estimated to be $154,577. These are 

capital/startup 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.
11

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

$1,162,379.

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

Managerial $62.27 (GS-13, Step 5, $38.92 + 60%)

Technical $46.21 (GS-12, Step 1, $28.88 + 60%)

Clerical $25.01 (GS-6, Step 3, $15.63 + 60%)

These rates are from the Office of Personnel Management (OPM) “2011 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 Nonmetallic 

Mineral Processing (40 CFR Part 60, Subpart OOO) (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

4,630.4 existing respondents will be subject to the standard. It is estimated that an additional 

66.4 respondents per year will become subject. The overall average number of respondents, as 

shown in the table below, is 4,697 (rounded). 

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

years covered by this ICR.

Average 66.4 4,630 0 0 4,697

1 Based on model plant parameters used in development of the original promulgated NSPS and the most recent 

production data available from the USGS, 332 new plants were projected over the 5-year NSPS review period. 

Thus, it is estimated that an additional 66.4 NMPP per year will become subject to the regulation over the three year 

ICR period (332/5 = 66.4). 

Column D is subtracted to avoid double-counting respondents. As shown above, the 

average Number of Respondents over the three year period of this ICR is 4,697.

The total number of annual responses per year is calculated using the following table:

The total annual labor costs are $1,185,697. Details regarding these estimates may be 

found in Table 1: Annual Respondent Burden and Cost − NSPS for Nonmetallic Mineral 

Processing (40 CFR Part 60, Subpart OOO) (Renewal).

6(e) Bottom Line Burden Hours Burden Hours and Cost Tables

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

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

(i) Respondent Tally

The total annual labor hours are 12,374. Details regarding these estimates may be found 

below in Table 1: Annual Respondent Burden and Cost − NSPS for Nonmetallic Mineral 

Processing (40 CFR Part 60, Subpart OOO) (Renewal).

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

information is estimated to average 2 hours per response. 

The total annualized capital/startup and O&M costs to the regulated entity are $154,577. 

The cost calculations are detailed in section 6(b)(iii), Capital/Startup vs. Operation and 

Maintenance (O&M) Costs.

(ii) The Agency Tally

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

25,793 labor hours at a cost of $1,162,379. See below Table 2: Average Annual EPA Burden and 

Cost − NSPS for Nonmetallic Mineral Processing (40 CFR Part 60, Subpart OOO) (Renewal). 
13

6(f) Reasons for Change in Burden

There is an increase in the labor hours for both the respondents and the Agency in this 

ICR compared to the previous ICR. This is due to two considerations. First, performance testing 

for existing sources will begin 5 years after the initial performance testing following the 2009 

ICR amendments, which corresponds to the third year of this renewal. Beginning in the third 

year of this ICR renewal, 60.9 sources would conduct 5-year repeat fugitive Method 9 

performance tests. These tests are only required for crushed/broken stone and sand/gravel 

facilities that do not have water sprays. This yields an annual average of 20.3 sources requiring 

Method 9 performance tests over the next 3 years. Secondly, there is an increase in the total 

number of respondents subject to the rule due to a growth in the respondent universe.

There is also an increase in the total labor and Agency costs as currently identified in the 

OMB Inventory of Approved Burdens. The change in cost estimates reflects the changes in 

respondent numbers (described above) and updated labors rates available from the U.S. Bureau 

of Labor Statistics. 

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’s 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-2011-0253. An electronic version of the public docket is 

available at http://www.regulations.gov which may be used to obtain a copy of the draft 

collection of information, submit or view public comments, access the index listing of the 

contents of the docket, and to access those documents in the public docket that are available 

electronically. When in the system, select “search,” then key in the docket ID number identified

TOTAL LABOR BURDEN AND COST (rounded) 12,374 $1,185,697

Assumptions:

a

 We have assumed that there are an average of 4,697 sources per year will be subject to the standard, and an additional 66.4 new sources that will become subject to the rule over 

the next three years. We have estimated that there are approximately 332 NMPP, which will become subject over a 5-year period, the number of new sources per year equals

(332/=66.4) for the additional new sources.

b

 This ICR uses the following labor rates: $121.42 per hour for Executive, Administrative, and Managerial labor; $99.14 per hour for Technical labor, and $49.81 per hour for 

Clerical labor. These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2011, “Table 2. Civilian Workers, by occupational and industry

group.” The rates are from column 1, “Total Compensation.” The rates have been increased by 110% to account for the benefit packages available to those employed by private 

industry.

c Monitoring for wet suppression involves checking that water is actually flowing. This is estimated to take 10 minutes per check and to occur on a monthly basis. Wet suppression 

is expected to be used in the following sectors: crushed/broken stone, and sand/gravel. The number of new sources per year from these sectors over the next three years is expected

to be 60.9.

d

 We have assumed that it will take each respondent 1 hour four times per year to complete Method 22 readings. All industry sectors except for crushed/broken stone and sand/

gravel are expected to use baghouses and will employ baghouse Method 22 readings to comply with the periodic monitoring requirements. The number of new sources per year

from these sectors over the next three years is expected to be 5.5.

e

 Performance tests include 8 hours to develop and review a performance test report and 22 hours to plan for the performance tests. The time required to conduct Method 5 and 

Method 9 tests are included in capital costs because a contractor is typically hired to perform the tests.

f

 We have assumed that 25% of initial performance tests must be repeated due to failure.

g

 We have assumed that performance testing for existing sources will not occur until 5 years after the initial performance testing, which is the 6th year of the ICR (i.e. the third year 

of this renewal). Beginning in the third year of this ICR renewal, 60.9 sources per year would conduct 5-year repeat fugitive Method 9 performance tests. These tests are only 

required for crushed/broken stone and sand/gravel facilities that do not have water sprays.

h We assume the average number of affected facilities over the next three years is represented by the number of sources in year 2 (66.4 new in first and second years and 4,564

existing sources in the first year) for a total of 4,697.

Assumptions:

a We have assumed that there are an average of 4,697 sources per year will be subject to the standard, and an additional 66.4 new sources that will become subject to the rule over the

next three years. We have estimated that there are approximately 332 NMPP, which will become subject over a 5-year period, the number of new sources per year equals (332/=66.4)

for the additional new sources.

b

 This cost is based on the following hourly labor rates times a 1.6 benefits multiplication factor to account for government overhead expenses: $62.27 for Managerial (GS-13, Step 5, 

$38.92 x 1.6), $46.21 for Technical (GS-12, Step 1, $28.88 x 1.6), and $25.01 Clerical (GS-6, Step 3, $15.63 x 1.6). These rates are from the Office of Personnel Management (OPM)

“2011 General Schedule” which excludes locality rates of pay.

c

 We have assume 25% of initial performance tests must be repeated due to failure.

d

 We have assumed that each new respondent will take 0.5 hours once per year to complete task.

e

 We have assumed that each new respondent will take eight hours once per year to review test results.

f We have assumed that each new respondent will take four hours to twice per year to complete emission reports.

g We have assumed that the average number of affected facilities over the next three years is estimated by the number of affected facilities in the second year (66.4 new in first year

and 66.4 in the second year, and 4,564 existing in the first year) for a total of 4,697.
