NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (Renewal)

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (Renewal), EPA ICR Number 1611.12, OMB Control Number 2060-0327. 

      1(b) Short Characterization/Abstract	

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) were proposed on December 16,1993, promulgated on January 25, 1995, and most-recently amended on February 27, 2014 (79 FR 11228). These regulations apply to both existing facilities and new facilities. New facilities include those that commenced construction, modification, or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart N.

      In general, all NESHAP 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 NESHAP. 

--------------------------------------------------------------------------------
      Any owner/operator subject to the provisions of this part shall maintain a file containing these documents, and retain the file for at least five years following the generation date of such maintenance reports and records. All reports are sent to the delegated state or local authority.     If there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The `burden' to the "Affected Public" may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (Renewal). The `burden' to the Federal Government is attributed entirely to work performed by either Federal employees or government contractors and may be found below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (Renewal). There are approximately 1,343 chromium electroplating and anodizing facilities, which are owned and operated by the chromium electroplating and chromium anodizing tank industry. This estimate consists of 652 hard chromium electroplating facilities, 517 decorative chromium electroplating facilities, and 174 chromium anodizing facilities. None of the 1,343 facilities in the United States are owned by either state, local, tribal or the Federal government. They are all owned and operated by privately-owned, for-profit businesses. We assume that they will all respond to EPA inquiries. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, approximately 1,343 respondents per year will be subject to these standards, and no additional respondents per year will become subject to these same standards. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
2. Need for and Use of the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      2(a) Need/Authority for the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
	The EPA is charged under Section 112 of the Clean Air Act, as amended, to establish standards of performance for each category or subcategory of major sources and area sources of hazardous air pollutants. These standards are applicable to new or existing sources of hazardous air pollutants and shall require the maximum degree of emission reduction. 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, chromium emissions from hard and decorative chromium electroplating and chromium anodizing tanks either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. There-fore, the NESHAP were promulgated for this source category at 40 CFR Part 63, Subpart N.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      2(b) Practical Utility/Users of the Data
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The recordkeeping and reporting requirements in these 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 standards. During the performance test a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The notifications required in these standards are used to inform either the Agency or its delegated authority when a source becomes subject to the requirements of these regulations. The reviewing authority may then inspect the source to check if the pollution control devices are properly installed and operated and leaks are being detected and repaired and that the standards are being met. The performance test may also be observed.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The required quarterly, semiannual, and annual 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 63,      Subpart N.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 (82 FR 29552) on June 29, 2017. No comments were received on the burden published in the Federal Register for this renewal. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 these standards, 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. Approximately 1,343 respondents will be subject to these standards over the three-year period covered by this ICR.

      Industry trade association(s) and other interested parties were provided an opportunity to comment on the `burden' associated with these standards as they were being developed and that these same standards have been reviewed previously to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both the National Association for Surface Finishing (NASF), at (202) 457-0630, and Conventya, at (216) 351-1500.

      It is our policy to respond after a thorough review of comments received since the last ICR renewal, as well as to those comments submitted in response to the first Federal Register notice. In this case, 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 these 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These standards require the respondents to maintain all records, including reports and notifications for at least five years. This is consistent with the General Provisions as applied to these standards. EPA believes that the five-year records retention requirement is consistent with the Part 70 permit program and the five-year statute of limitations on which the permit program is based. The retention of records for five years allows EPA to establish the compliance history of a source, any pattern of non-compliance and to determine the appropriate level of enforcement action. EPA has found that the most flagrant violators have violations extending beyond five years. In addition, EPA would be prevented from pursuing the violators due to either the destruction or nonexistence of essential records.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 these standards do not include sensitive questions.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
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 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 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. The 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 five years.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(c) Small Entity Flexibility
--------------------------------------------------------------------------------

      The majority of the respondents are small businesses. The recordkeeping and reporting requirements were selected within the context of this specific subpart and the specific process equipment and pollutant. The impact on small businesses was accounted for in the regulation development. Reduction in reporting was provided to small businesses subject to this regulation. Small (area source) businesses are only required to prepare annual compliance status reports and may retain these reports on site. These reports must be submitted to either the Agency or a delegated authority on a semiannual basis only where the duration of excess emissions and air pollution control device malfunctions exceeds specified thresholds. Large (major source) facilities must prepare and submit these reports on a semiannual or quarterly basis depending on their performance. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing  Tanks (40 CFR Part 63, Subpart N) (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 neither conduct nor 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 242,000 hours (Total Labor Hours from Table 1 below). These hours are based on Agency studies and background documents from the development of the regulations, Agency knowledge and experience with the NESHAP 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	$149.35 ($71.12 + 110%)  
--------------------------------------------------------------------------------
            Technical	$112.98 ($53.80 + 110%)
--------------------------------------------------------------------------------
            Clerical	$54.81 ($26.10 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2017, "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(s) 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 monitor(s) and other costs such as photocopying and postage.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The total capital/startup costs for this ICR are $0. This is the total of column D in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $20,400,000.         This particular sum 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 $20,400,000.  These are the 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 such activities 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 $184,000. 
--------------------------------------------------------------------------------

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

		Managerial	$64.80 (GS-13, Step 5, $40.50 + 60%) 
		Technical	$48.08 (GS-12, Step 1, $30.05 + 60%)
		Clerical	$26.02 (GS-6, Step 3, $16.26 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      These rates are from the Office of Personnel Management (OPM), 2017 General Schedule, which excludes locality rates of pay. The rates have been increased by 60 percent to account for the benefit packages available to Federal government employees. Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (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 1,343 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 1,343 per year. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The number of respondents is calculated using the following table that addresses the three years covered by this ICR:

    *We assume that all sources are area sources. Area sources, except for 52 decorative chromium electroplating plants using trivalent chromium bath, (1,343  -  52 = 1,291) are required to submit an annual compliance status report.  However, sources are required to submit these reports on a more frequent basis if excess emissions occurs (i.e., semiannually for area sources).  We further assume that 80 percent of the sources (0.80 times 1,291 yields 1,033) will have no excess emissions and 20 percent of the sources (0.20 times 1,291 yields 258) will have excess emissions. Half of the area sources submitting semiannual reports due to excess emissions (0.5 x 258 = 129) will request the regulatory agency to approve a reduction in frequency for ongoing compliance status reports (i.e., annual reporting).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The number of Total Annual Responses is 1,730. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual labor costs are $26,500,000.00 (rounded). Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR part 63, subpart N) (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 below in Tables 1 and 2, respectively, and summarized below. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i) Respondent Tally
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual labor hours are 242,000 hours. Details regarding these estimates may be found below in Table 1. Annual Respondent Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR Part 63, Subpart N) (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 140 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $20,400,000. 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 3,920 labor hours at a cost of 184,000; see below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Chromium Emissions from Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks (40 CFR part 63, subpart N) (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 was no change in the labor hours in this ICR compared to the previous ICR for several reasons. First, the regulations have not changed over the past three years and are not anticipated to change over the next three years, plus there was no change in the capital or O&M costs.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(g) Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 140 hours per response. `Burden' means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information either 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 neither conduct nor 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.

[a]  There are an estimated total of 1,343 chromium electroplating and anodizing operations nationwide.  Of this total, approximately 652 are hard chromium electroplating operations, 517 are decorative chromium electroplating operations, and 174 are chromium anodizing operations.  No net growth is predicted for this industry.  It is expected that new tanks will only be added to replace or expand existing capacity.  The ongoing monitoring, reporting, and recordkeeping for new tanks is the same as that for existing tanks.
[b] This ICR uses the following labor rates:  $149.35 per hour for Executive, Administrative, and Managerial labor; $112.98 per hour for Technical labor, and $54.81 per hour for Clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, June 2017 "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]  Sources are required to conduct performance tests using Methods 306 or 306A of Appendix A, or the California Air Resources Board (CARB) Method 425 or SCAQMD Method 205.1, as an alternative, Method 306B, and alternate methods if the method has been validated using Method 301 of Appendix A. 
[d]  Sources are required to follow work practice standards at composite-mesh-pad (CMP) systems, packed-bed scrubbers (PBS), PBS/CMP systems, fiber-bed mist eliminators, and other air pollution control devices not listed in the rule, as well as monitoring operational parameters (i.e., pressure drop for composite mesh pad systems and fiber bed mist eliminators; pressure drop and velocity pressure for packed bed scrubbers, surface tension for wetting agents,  thickness of the foam for foam blanket fume suppressants, or the appropriate parameter for an alternative control option) and monitoring equipment.
[e]  Since there are no new respondents estimated, these requirements do not apply.
[f]  All sources, except decorative chromium electroplating plants using trivalent chromium bath (1,343 - 51.7 = 1,291.3), are required to submit compliance status reports.  Area sources are required to submit an annual compliance status report and major sources a semiannual compliance status report.
[g]  If excess emissions occur at the plant, sources are required to submit reports on a more frequent basis (i.e., semiannually for area sources and quarterly for major sources) until the regulatory agency has approved the source request to reduce frequency of ongoing compliance status reports.  We have assumed that 80 percent of the sources (0.80 x 1,291.3 = 1,033.04) will have no excess emissions and 20 percent of the sources (0.20 x 1,291.3 = 258.26) will have excess emissions. We have also assumed that half of the area sources submitting semiannual reports due to excess emissions (0.5 x 258 = 129.13) will request the regulatory agency to approve a reduction in frequency for ongoing compliance status reports (i.e., back to annual reporting).  
[h]  We have assumed that all sources are area sources.  
i  We have assumed that the monitoring required for composite mesh pad/packed bed scrubbers occurs once per day, 5 five days a week, 50 weeks per year for all plants with add-on control devices.  The number of facilities with add-on control devices is estimated to be 639.49 based on the assumption that 84 percent of hard chromium electroplating facilities (84% of 652 = 547.68), 13 percent of the decorative chromium electroplating that use hexavalent chromium bath (13% of 465.3 = 60.49) and 18 percent of chromium anodizing facilities (18% of 174 = 31.32) will use add-on control devices.   
[j]  We have assumed that 85 percent of decorative chromium electroplating plants that use hexavalent chromium bath (85% of 465.3 = 395.51) and 70 percent of chromium anodizing plants (70%  of 174 = 121.8) will use wetting agents for a total of 517.31 sources. 
k  We have assumed that area sources using wetting agents will be required to monitor once every four hours for two 8-hours shifts (a 16-hour day), five days a week, 50 weeks per year per operating schedule if the source is on a regular monitoring schedule.  If the source is on a reduced monitoring schedule, it will be required to monitor once every 40 hours for 16-hour day, five days a week, 50 weeks per year per operating schedule.  We have assumed that 90 percent of the sources (90% of 517.31 = 465.57) will be on a normal schedule and 10 percent of the sources (10% of 517.31 = 51.73) are on a reduced schedule.
[l]  We have assumed that sources will not elect to use foam blankets because the rule requires them to do compliance testing.  If sources elect to use foam blankets, the reduced monitoring schedule will require them to monitor once every 8 hours, per 16-hour day, five days a week, 50 weeks per year per operating schedule.  If the source is on a normal monitoring schedule it will be required to monitor once every hour, per 16-hour day, five days a week, 50 weeks per year per operating schedule. 
[m]  We have assumed that all facilities with add-on control devices (639.49) would be required to have an approved Operation and Maintenance Plan for their operations.
[n]  We have assumed that 10 percent of the decorative chromium electroplating plants (10% of 517 = 51.7) use trivalent chromium baths and 90 percent use hexavalent chromium baths (90% of 517 = 465.3).
o  Totals have been rounded to 3 significant figures.  Figures may not add exactly due to rounding.

[a]  There are an estimated total of 1,770 chromium electroplating and anodizing operations nationwide.  Of this total, approximately 652 are hard chromium electroplating operations, 517 are decorative chromium electroplating operations, and 174 are chromium anodizing operations.  No net growth is predicted for this industry.  It is expected that new tanks will only be added to replace or expand existing capacity.  The ongoing monitoring, reporting, and recordkeeping for new tanks is the same as that for existing tanks.
[b]  This cost is based on the following hourly labor rates: $64.80 for Managerial (GS-13, Step 5, $40.50 + 60%), $48.08 for Technical (GS-12, Step 1, $48.08 + 30.05%) and $26.02 Clerical (GS-6, Step 3, $16.26 + 60%).  These rates are from the Office of Personnel Management (OPM) "2017 General Schedule" which excludes locality rates of pay. The rates have been increased by 60% to account for the benefit packages available to government employees.
[c]  Since there are no new respondents estimated, these requirements do not apply.
d  There will be no periodic burden for the regulatory agency associated with this requirement although we have assumed that all facilities with add-on control devices (639) would be required to have an approved Operation and Maintenance Plan for its operations. 
[e] Assumes Agency will review records of 5% of the 540 plants that use fume suppressants (540 x 0.05 = 26) to confirm that non-PFOS fume suppressants are being used.
f All sources, except decorative chromium electroplating plants using trivalent chromium bath (1,343 - 51.7 = 1,291.3), are required to submit compliance status reports.  Area sources are required to submit an annual compliance status report and major sources a semiannual compliance status report.
[g] If excess emissions occur at the plant, sources are required to submit reports on a more frequent basis (i.e., semiannually for area sources and quarterly for major sources) until the regulatory agency has approved the source request to reduce frequency of ongoing compliance status reports.  We have assumed that 80 percent of the sources (0.80 x 1,291.3 = 1,033.04) will have no excess emissions and 20 percent of the sources (0.20 x 1,291.3 = 258.26) will have excess emissions. We have also assumed that half of the area sources submitting semiannual reports due to excess emissions (0.5 x 258 = 129.13) will request the regulatory agency to approve a reduction in frequency for ongoing compliance status reports (i.e., back to annual reporting).  
[h]  We have assumed that all sources are area sources.  
[i]  Totals have been rounded to 3 significant figures.  Figures may not add exactly due to rounding.
