SUPPORTING STATEMENT

ENVIRONMENTAL PROTECTION AGENCY

NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) (Renewal)

1. Identification of the Information Collection

1(a) Title of the Information Collection

NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db)

1(b) Short Characterization/Abstract

The New Source Performance Standards (NSPS) for the regulations published at 40 CFR part 60, subpart Db for the pollutant sulfur dioxide (SO₂) were proposed on June 19, 1986, and promulgated on December 16, 1987. These regulations apply to industrial-commercial-institutional steam generating units (boilers) that commenced construction, modification, or reconstruction after June 19, 1984, and that have a heat input capacity from fuels combusted in the unit of greater than 29 MW (100 million Btu/hour). The regulations were amended on February 27, 2006 (71 FR 9865), June 13, 2007 (72 FR 32710), and on January 28, 2009 (74 FR 5086). This ICR is updated to reflect changes due to the 2007 and 2009 amendments. The 2007 amendments added compliance alternatives, revised certain recordkeeping and reporting requirements, corrected technical and editorial errors, and updated the grammatical style of the four D subparts. The 2009 amendments clarified the intent for applying and implementing specific rule requirements, provided additional compliance alternatives, and corrected unintentional technical omissions and editorial errors. This information is being collected to assure compliance with 40 CFR part 60, subpart Db.

In general, all NSPS standards require initial notifications, performance tests, and periodic reports. Owners or operators 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 sources 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. In the event that there is no such delegated authority, the reports are sent directly to the United States Environmental Protection Agency (EPA) regional office.

Size of the Regulated Community

In a study from 1979, EPA modeled the total capacity of United States (U.S.) industrial/commercial boilers for 1980, 1985 and 2000, for boilers with capacities greater than 29 MW (100 million BTU/hour) (“Population and Characteristics of Industrial/Commercial Boilers in the United States from 1979"; EPA Number PB80 - 150881). This model shows an increase of 4,139 new industrial/commercial boilers between 1985 and 2000 with capacities greater than 29 MW (100 million BTU/hour), and these would be subject to NSPS Db. Therefore, according to this model there should be approximately 4,139 steam generating units (or boilers) currently subject to NSPS subpart Db. Assuming one boiler per facility, the number of facilities subject to NSPS subpart Db would be 4,139.

However, during the nitrogen oxide (NO_x) NSPS revision, information on industrial boilers subject to NSPS Db was obtained from three sources: a best available technology/ lowest achievable emission rate database search; copies of permits obtained from EPA regional offices; and telephone contacts with EPA regions, state agencies, and boiler vendors. Based on the information obtained, as of 1995, only 45 NSPS Db boilers were identified. Since NSPS Db was in effect for ten years in 1995, 45 boilers is probably a low number and model projects indicate that it may be far from the true regulated universe for 1995. The Information Collection Request (ICR) approved in 2000 estimated 957 facilities subject to NSPS Db.

During the NO_x NSPS revision mentioned above, an analysis was conducted to determine the projected growth of new industrial boilers over the period from 1996 to 2000. This analysis showed that the growth rate would be 76 new industrial boilers per year. Therefore, using the estimate from the ICR approved in 2000 of 957 sources, assuming a growth rate of 76 new industrial boilers per year over the three-year period since the last ICR, and assuming one boiler per facility, the 2003 ICR estimated 1,185 existing NSPS Db facilities. The 2006 ICR renewal assumed no change in the total estimate of 1,185 existing NSPS Db facilities.

Growth Rate for the Next Three Years

In the Industrial Boiler Maximum Achievable Control Technology (MACT) rulemaking, a projection of new industrial, commercial, and institutional boilers was performed for economic analysis in October 2002. This analysis showed that 134 industrial, commercial, and institutional boilers would become subject to NSPS subpart Db over the next three years (or 45 per year). This is the most recent growth projection available for these facilities.

This ICR estimates the existing number of sources based on the 2003 ICR estimate of 1,185 existing sources plus 270 new facilities over a six-year period (assuming a growth rate of 45 facilities per year over six years). Therefore, this ICR is estimating that approximately 1,455 existing sources are currently subject to the regulation; and it is estimated that an additional 45 new sources per year will become subject to the regulation in the next three years.

The Office of Management and Budget (OMB) approved the currently active ICR without any “Terms of Clearance.”

The burden to the “Affected Public” may be found in Table 1: Annual Respondent Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR part 60, subpart Db). The burden to the “Federal Government” is attributed entirely to work performed by Federal employees or government contractors; this burden may be found in Table 2: Average Annual EPA Burden - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR part 60, subpart Db).

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/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 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, SO₂, particulate matter (PM), and NO_x emissions from Industrial-Commercial-Institutional Steam Generating units 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 Db.

2(b) Practical Utility/Users of the Data

The control of emissions of SO_2, PM, and NO_x from Industrial-Commercial-Institutional Steam Generating units requires not only the installation of properly designed equipment, but also the operation and maintenance of that equipment. Emissions of SO₂, PM, and NO_x from Industrial-Commercial-Institutional Steam Generating units are the result of operation of the affected facilities. The subject standards are achieved by the capture and/or reduction of SO₂, PM, and NO_x emissions using control technologies such as sorbent injection technologies and wet and dry scrubbers for SO₂; cyclones, electrostatic precipitators, and fabric filters for PM; and low NO_x burners and selective catalytic or noncatalytic reduction technologies for NO_x.

The notifications required in the applicable regulations 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 regulations are being met.

Performance test reports are needed as these are the Agency's record of a source's initial capability to comply with the emission standards, and serve as a record of the operating conditions under which compliance was achieved. Continuous emission monitors are used to ensure compliance with the standards at all times.

The information generated by the monitoring, recordkeeping and reporting requirements described in this ICR is used by the Agency to ensure that facilities affected by the NSPS continue to operate the control equipment and achieve compliance with the regulation. Adequate monitoring, recordkeeping, and reporting are necessary to ensure compliance with the applicable regulations, as required by the Clean Air Act. The collected information is also used for targeting inspections and as evidence in legal proceedings.

The required quarterly or semiannual reports are used to determine periods of excess emissions, identify problems at the facility, verify operation/maintenance procedures and for compliance determinations.

3. Nonduplication, Consultations, and Other Collection Criteria

The requested recordkeeping and reporting are required under 40 CFR part 60, subpart Db.

3(a) Nonduplication

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, no duplication exists.

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 (74 FR 38004) on July 30, 2009. No comments were received on the burden published in the Federal Register.

3(c) Consultations

In determining the correct burden estimate associated with this ICR, industry trade associations and other interested parties have been provided an opportunity to comment on the burden associated with the standard as it was being developed and in subsequent renewals of the ICR. It is our policy to review any comments received since the last ICR renewal including those submitted in response to the first Federal Register notice and respond appropriately. EPA published an announcement of a public comment period for the renewal of this ICR in the Federal Register on July 30, 2009. No comments were received on respondent burden associated with the reporting and recordkeeping requirements provided in this ICR.

To determine the size of the regulated community and the rate of industry growth, the EPA Office of Air Quality Planning and Standards was consulted. The Agency’s internal industry experts have been consulted. The Agency’s internal data sources and projections of industry growth over the next three years also have been considered.

Another source of information from the 2003 renewal was the information provided by the industry. Information provided in the industry reports is located in the EPA’s AFS (Air Facility System) database. In 2003, approximately 1,230 respondents were subject to the regulation.

It should be noted that the 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.

For this renewal, EPA contacted a representative industry trade organization to request a voluntary opinion as to the accuracy of the burden estimates associated with this ICR and whether there is any way to reduce the burden. EPA contacted the Council of Industrial Boiler Owners (CIBO, Bob Bessette, telephone: 703-530-9042); no comments were received.

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 (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

Industrial-commercial-institutional boilers (also known as steam generating units) are classified by type, fuel, and method of construction. The three main types are cast iron, fire tube, and water tube. These three categories of boilers are designed and manufactured to meet specific applications and site requirements. Unit size, design pressure and temperature all depend on boiler application. Each boiler type may burn coal, oil, or natural gas, and increasingly are being designed to burn more than one fuel type.

All boilers subject to NSPS subpart Db are water tube boilers. Water tube boilers are used in a variety of applications ranging from supplying large amounts of process steam to providing space heat for industrial facilities, or commercial buildings. Water tube boilers are fueled by coal, 25 percent; oil, 32 percent, and natural gas, 43 percent. Process steam accounts for the largest use of fuel to fire boilers, using about one-third of all industrial fuel.

The following industries use water tube boilers with capacities greater than 29 MW (100 mmBtu/hr). In EPA studies, energy usage was used to estimate the potential for industry boiler usage. The chemical and paper industries use the most energy accounting for about a third of all U.S. industrial fuel usage. Petroleum refineries, steel and aluminum manufacturers, and food processing industries use most of the remainder of industrial fuel. Other industries using smaller, but significant amounts of fuel are the textiles, lumber, and rubber manufacturers, and metal fabrication and transportation industries. The other two industries that would be expected to have boilers large enough to be subject to NSPS subpart Db are office and shopping center heating and boiler rentals.

The respondents to the recordkeeping and reporting requirements are facilities subject to NSPS subpart Db that commenced construction, modification, or reconstruction after June 19, 1984, and that have a heat input capacity from fuels combusted in the steam generating unit of greater than 29 MW (100 mmBtu/hr).

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 still not widely used. At this time, it is estimated that approximately 20 percent of the respondents use electronic reporting.

(ii) Respondent Activities

Respondent Activities

Read instructions.

Install, calibrate, maintain, certify, and operate Continuous Emission Monitoring Systems for NO_x, SO₂, and opacity or alternative monitoring methods (e.g., CO CEMS in place of using a COMS).

Perform initial performance test.

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.

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

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 Air Facility System (AFS).

5(b) Collection Methodology and Management

Following notification of startup, the reviewing authority might 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 the AFS which is operated and maintained by the EPA Office of Compliance. AFS is EPA’s database for the collection, maintenance, and retrieval of compliance data for approximately 125,000 industrial and government-owned facilities. EPA uses the AFS 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

According to the 2005 Economic Impacts Analysis for the Proposed NSPS amendments in 2005 (see Docket ID: EPA-HQ-OAR-2005-0031-0059) 2 of the 17 or 12 percent of the projected new biomass units were expected to be small entities. Applying this percent to the respondent universe for this ICR results in approximately 180 small entities impacted by this ICR..

5(d) Collection Schedule

The specific frequency for each information collection activity within this request is shown in below Table 1: Annual Respondent Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR part 60, subpart Db).

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.

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 771,889 hours (Total Labor Hours from Table 1). The recordkeeping hours shown in Table 1 are 234,045. The reporting requirement hours shown in Table 1 are 537,844. 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 $114.77 ($54.65 + 110%)

Technical $97.59 ($46.47 + 110%)

Clerical $48.26 ($22.98 + 110%)

These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2009, “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 type of industry costs associated with the information collection activities in the subject standard 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.

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

Capital/Startup vs. Operation and Maintenance (O&M) Costs
(A) Continuous Monitoring Device	(B) Startup Cost ($) for One Affected Facility	(C) Number of New Affected Facilities to Startup	(D) Total Startup (B X C)	(E) Annual O&M Costs ($) for One Affected Facility	(F) Number of Affected Facilities with O&M	(G) Total O&M (E X F)
SO2, PM, and NOx	$200,000	45	$9,000,000	$15,000	1,500	$22,500,000

The total capital/startup costs for this ICR are $9,000,000. This is the total of column D in the above table.

The total operation and maintenance (O&M) costs for this ICR are $22,500,000. This is the total of column G.

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 $31,500,000. These are recordkeeping 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 $27,885,868 (see Table 2).

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

Managerial $61.36 (GS-13, Step 5, $38.35 + 60%)

Technical $45.52 (GS-12, Step 1, $28.45 + 60%)

Clerical $24.64 (GS-6, Step 3, $15.40 + 60%)

These rates are from the Office of Personnel Management (OPM), 2009 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: Annual Agency Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db).

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

Approximately 1,455 sources are currently subject to the regulation, and it is estimated that an additional 45 sources per year will become subject to the regulation in the next three years.

Respondent Universe and Number of Responses Per Year
Regulation Citation	(A) Average Number of New Respondents per Year	(B) Number of Reports for New Sources	(C) Number of Existing Respondents	(D) Number of Reports for Existing Sources	(E) Number of Respondents That Keep Records But Do Not Submit Reports	(F) Total Annual Responses = (AxB)+(CxD)+ E
40 CFR 60.49b (w)	36	2	1,164	2	0	2,400
40 CFR 60.49b (v)	9	4	291	4	0	1,200
Total	45		1,455			3,600

The number of total respondents is 1,500. This number is the sum of column A and column C of the Respondent Universe and Number of Responses Per Year table. This represents the number of existing sources and the number of new sources averaged over the three-year period (i.e., the number of new respondents over the three-year period divided by three years).

The number of Total Annual Responses is 3,600.

The total annual labor costs are $63,338,557. Details upon which this estimate is based appear in Table 1: Annual Respondent Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db).

The total annual capital and O&M costs to the regulated entities are $31,500,000.

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 771,889. Details regarding these estimates may be found in Table 1. Annual Respondent Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db) (below). Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 214 hours per response.

The total annual capital/startup and O&M costs to the regulated entity are $31,500,000. 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 next three years is estimated to be 777,014 labor hours at a cost of $27,885,868. See Table 2: Annual Agency Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db).

6(f) Reasons for Change in Burden

The increase in burden from the most recently approved ICR is due to adjustment. Growth rate in the number of existing sources since previous approved ICRs has been taken into account, along with projected growth rate for the three years covered by this ICR. The total number of respondents has increased from 1,185 to 1,500 which results in a larger number of respondents, responses, and burden hours.

The increase in burden is also related to calculation errors in the previous ICR calculations in Table 1: Annual Respondent Burden and Cost - NSPS for Industrial-Commercial-Institutional Steam Generating Units (40 CFR Part 60, Subpart Db). Corrections have been made to Table 1 of this ICR.

The respondent and Agency labor costs have also increased. Also, while the previous ICR used only a technical rate, Tables 1 and 2 of this ICR reflect burden and cost calculations expanded to include managerial and clerical labor rates.

6(g) Burden Statement

The annual public reporting and recordkeeping burden for this collection of information is estimated to average 214 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-2009-0528.

Footnotes:

a) This ICR uses the following labor rates: Managerial $114.77 ($54.65 + 110%); Technical $97.59 ($46.47 + 110%); and Clerical $48.26 ($22.98 + 110%). These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2009, 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. This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10 percent of Technical hours.

b) EPA estimates that there will be 26 new gas-fired steam generating units per year (which require NOx controls), 13 new coal-fired generating units per year (which require SO₂, NOx, and PM controls), and 6 new biomass/wood (which require NOx and PM controls).

c) One-time only costs associated with the anticipated 45 new sources per year over the next three years. According to the 2003 ICR renewal, approximately half of all new sources will submit a monitoring plan.

d) Assume 20 percent of initial performance tests and CEMS demonstrations are repeated due to failures.

e) According to the 2003 ICR renewal, there are 640 sources that must report SO₂ emissions, 622 sources that must report PM emissions, and 1322 sources that must report NOx emissions. Because these existing source estimates were from 2003, this ICR renewal adds 270 additional existing sources since the 2003 ICR renewal (45 sources times six years) to update the total number of existing sources reported each type of pollutant. These 270 sources are split out according to the same distribution of gas, coal, and biomass units listed in note (b) above. To estimate the total number of respondents for each type of pollutant reporting, the existing sources subject to each type of pollutant reporting were added to the 45 new sources per year and these new sources were distributed according to note (b).

f) Assume that 20 percent of respondents will choose to report quarterly.

g) Assume the 20 percent of units are found to be in excess of emission standard, 80 percent are found to be in no excess.

h) According to the 2003 ICR renewal, 57 percent of all sources submit an Appendix F Report for SO₂, and the remaining 43 percent submit an Appendix F Report for NOx.

i) Appendix F audit costs are based on contractor costs of $50.00 per hour.

j) Assume that 25 percent of units have in situ CEMS and 75 percent have extractive CEMS.

Footnotes:

a) This ICR uses the following labor rates: Managerial $61.36 (GS-13, Step 5, $38.35 + 60%); Technical $45.52 (GS-12, Step 1, $28.45 + 60%); and Clerical $24.64 (GS-6, Step 3, $15.40 + 60%).
These rates are from the Office of Personnel Management (OPM), 2009 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. This ICR assumes that Managerial hours are 5 percent of Technical hours, and Clerical hours are 10 percent of Technical hours.

b) All new plants subject to the standard must provide reports of these events as required by section 60.7. These are one-time-only costs associated with the anticipated 45 new sources per year over the next three years. According to the 2003 ICR renewal, approximately half of all new sources will submit a monitoring plan.

c) EPA estimates that there will be 26 new gas-fired steam generating units per year (which require NOx controls), 13 new coal-fired generating units per year (which require SO₂, NOx, and PM controls), and 6 new biomass/wood (which require NOx and PM controls).

d) The average number of new sources for each control for SO₂, PM and NOx have been determined according to assumption (b) in Table 1 above, accounting for industry growth during the years since the ICR renewal of the year 2003, and added to the number of existing sources required to submit reports for each type of pollutant. The estimates for the number of existing sources are in note (e) of Table 1 above.

e) We assume that 20 percent of respondents will choose to report quarterly.

f) Travel expenses (1 person x 15/plants/yr x 3 days/plant x $75 per diem) + ($250 round trip/plant x 15 plants/yr).
