NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal)

1. Identification of the Information Collection

      1(a) Title of the Information Collection

NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL)         (Renewal), EPA ICR Number 1767.08, OMB Control Number 2060-0360. 

      1(b) Short Characterization/Abstract	

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) were proposed on September 26, 1996, promulgated on October 7, 1997, and most-recently amended on October 15, 2015. The 2015 amendment includes: 1) polycyclic organic matter (POM) emission limits for new, existing and reconstructed prebake potlines; 2) revised POM limits for new, existing and reconstructed Soderberg potlines; 3) carbonyl sulfide (COS) emission limits for new, existing and reconstructed potlines; 4) POM emission limits for existing pitch storage tanks; 5) particulate matter (PM) emission limits for new, existing and reconstructed potlines, paste production plants and anode bake furnaces; 6) mercury (Hg) limits for new, existing and reconstructed anode bake furnaces; 7) arsenic, nickel and polychlorinated biphenyl (PCB) limits for new, existing and reconstructed Soderberg potlines; 8) new work practice standards for anode bake furnaces, paste production plants and potlines; and 9) eliminates the exemptions for periods of startup, shutdown, and malfunctions (SSM). The amendment also reduces the testing frequency for total fluoride (TF) from prebake and Soderberg potlines and POM from Soderberg potlines from monthly to semiannually.  These regulations apply to the following affected sources at a primary aluminum reduction plant are covered: each new and existing pitch storage tank, potline, paste production plant and anode bake furnace that is located at a plant site that is a major source as defined at §63.2 (except for anode bake furnaces that are not located on the same site as a primary aluminum reduction plant). New facilities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart LL.

      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 this 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. 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      All of the primary aluminum reduction plants in the United States are owned and operated by the primary aluminum reduction industry (aka: the "Affected Public"). None of the 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. The "burden" to the Affected Public may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal). The Federal Government's "burden" 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 Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal). 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Over the next three years, approximately 11 respondents per year will be subject to these standards, and no additional respondents per year will become subject to these same standards.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The active (previous) ICR had the following Terms of Clearance (TOC): 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
            In accordance with 5 CFR 1320, the information collection is approved for three years.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      EPA has addressed each item of concern in the TOC by renewing this ICR before the end of the three-year approval period. 

--------------------------------------------------------------------------------
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, total fluoride (TF), polycyclic organic matter (POM), particulate matter (PM), nickel, arsenic, polychlorinated biphenyl (PCB), mercury (Hg), and carbonyl sulfide emissions from primary aluminum reduction plants either cause or contribute to air pollution that may reasonably be anticipated to endanger public health and/or welfare. Therefore, the NESHAP were promulgated for this source category at 40 CFR Part 63, Subpart LL.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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. Continuous emission monitors are used to ensure compliance with these same standards at all times. During the performance test a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in these 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, leaks are being detected and repaired and the standard is being met. The performance test may also be observed.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The required semiannual 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 LL.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(c) Consultations

      The Agency has consulted industry experts and internal data sources to project the number of affected facilities and industry growth over the next three years. The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in the standard, is the Integrated Compliance Information System (ICIS). ICIS is EPA's database for the collection, maintenance, and retrieval of compliance data for industrial and government-owned facilities. The growth rate for the industry is based on our consultations with the Agency's internal industry experts.

      Industry trade association(s) and other interested parties were provided an opportunity to comment on the burden associated with the standard as it was being developed and the standard has been previously reviewed to determine the minimum information needed for compliance purposes. In developing this ICR, we contacted both: 1) the Aluminum Association, at (703) 358-2960; and 2) Alcoa, Inc., at (412) 315-2900.

      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. 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 the 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 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
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.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The October 15, 2015 amendment requires that results from performance evaluations of CMS measuring relative accuracy test audit (RATA) pollutants be submitted via the Compliance and Emissions Data Reporting Interface (CEDRI). Only RATA pollutants supported by the EPA's electronic reporting tool (ERT) are required to be submitted via CEDRI; supported pollutants are those listed on EPA's ERT website at the time of the test. CEDRI can be accessed through the EPA's Central Data Exchange (CDX). Performance evaluation data must be submitted in a file format generated through the use of the EPA's ERT or in an electronic file format consistent with the XML schema listed on the EPA's ERT website once the XML schema is available. 
--------------------------------------------------------------------------------

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. 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 Small Business Administration defines a small entity engaging in Primary Aluminum Reduction as a firm having no more than 1,000 employees. There are no small entities (i.e., small businesses) affected by this regulation. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (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 71,900 hours (Total Labor Hours from Table 1 below). These hours are based on Agency studies and background documents from the development of these 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	$144.33 ($68.73+ 110%)  
--------------------------------------------------------------------------------
            Technical	$108.28 ($51.56 + 110%)
--------------------------------------------------------------------------------
            Clerical	$53.34 ($25.40 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2016, "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 these regulations. 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 operation and maintenance (O&M) costs for this ICR are $78,500. 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 $78,500.  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 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 $15,700. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 government employees. Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (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 11 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 11 per year. 
--------------------------------------------------------------------------------

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

      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 71,900 hours. Details regarding these estimates may be found below in Table 1: Annual Respondent Burden and Cost  -  NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      We assume that burdens for managerial tasks take 5% of the time required for technical tasks because the typical tasks for managers are to review and approve reports. Clerical burdens are assumed to take 10% of the time required for technical tasks because the typical duties of clerical staff are to proofread the reports, make copies and maintain records.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 2,996 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $78,500. 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 336 labor hours at a cost of $15,700; see below in Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal).

--------------------------------------------------------------------------------
      6(f) Reasons for Change in Burden
--------------------------------------------------------------------------------

      There is an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This decrease is primarily due to a program change. The 2015 amendment reduces the frequency of TF performance tests from monthly to semiannually. This ICR combines burden from the existing provisions with the burden associated with the 2015 amendment to the rule, resulting in a net decrease in burden. Additionally, the total number of affected sources has decreased as compared to the most recently approved ICR. 
      
      There is an adjustment decrease in the total estimated capital and O&M costs as compared to the most recently approved ICR. The decrease occurred because there is a    decrease in the total number of respondents subject to the rule. 
--------------------------------------------------------------------------------

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

Assumptions:
[a]  Assumes that there is an average of 11 respondents per year subject to the standards and that no additional respondents per year will become subject to the standards. 
[b]  This ICR uses the following labor rates:  $144.33 per hour for Executive, Administrative, and Managerial labor; $108.28 per hour for Technical labor, and $53.34 per hour for Clerical labor.  These rates are from the United States Department of Labor, Bureau of Labor Statistics, September 2016, "Table 2. Civilian Workers, by Occupational and Industry group."  The rates are from column 1, "Total Compensation."  The rates have been increased by 110 percent to account for the benefit packages available to those employed by private industry.
[c]  We have assumed all existing respondents will have to familiarize with the regulatory requirements each year. 
[d]  Assumes it takes 100 hours to complete each required TF, POM, PM, and Hg test for primary controls of potlines, bake furnaces and paste production plants.
[e]  We estimate a total of 144 annual tests (primary control systems). This estimate is based on the Final Cost Impacts for the Primary Aluminum Production Source Category for the 2015 amendments which estimates: 35 potlines and 8 pitch storage tanks will require annual POM testing; 37 potlines, 12 anode bake furnaces, and 10 paste production plants will require annual PM testing; 12 anode bake furnaces will require annual Hg testing; and 30 potlines will require annual testing for TF (Note: there are a total of 37 potlines that require TF testing; however, 7 potlines are located in states that already required testing). (35+8+37+12+10+12+30 =144 tests at 11 facilities = 13.09 tests/facility).
[f]  Assumes it takes 200 hours to test for secondary TF and PM emissions from potlines and 100 hours to test for secondary POM emissions from potlines.
[g]  We estimate a total of 180 tests for secondary emissions from potlines. This estimate is based on the Final Cost Impacts for the Primary Aluminum Production Source Category for the 2015 amendments which estimates: 35 potlines will require semiannual POM testing; 37 potlines will require semiannual PM testing; and 18 potlines will require semiannual testing for TF (Note: there are a total of 37 potlines that require TF testing; however, 7 potlines are located in states that already required testing and 12 potlines do not have manifolds installed and will use the Method 14A Alcan Cassette test). [(37+18) x 2 tests/year = 110 TF and PM tests/year at 11 facilities = 10 tests/facility. 35 x 2 tests/yr = 70 POM tests/year at 11 facilities = 6.36 tests/facility].
[h]  Assumes it takes 40 hours for testing of similar potlines (CEM or Alcan cassette).
[i]  Assumes that 12 potlines will not have manifolds installed and will use Alcan Cassette tests. (12x2/11 = 2.18 tests/facility).
j  Assumes it takes 200 hours for a Method 315 test for secondary emissions at Soderberg plants.
[k]  Per the Final Cost Impacts for the Primary Aluminum Production Source Category for the 2015 amendments the only remaining Soderberg plant in the U.S. has announced permanent shutdown. Therefore, no Soderberg plants will require quarterly testing.
[l]  Assumes that all existing sources have design specifications for pitch storage tank controls in place.
[m]  This rule requires that all existing respondents submit semiannual reports. Performance test results will be submitted with the semiannual reports.
[n]  Assumes that 10 percent fail to meet the standard (0.1x11 = 1.1, rounded to 1).
[o]  Assumes that 90 percent meet the standard (0.9x11 = 9.9, rounded to 10).
[p]  Assumes that 10 percent must file malfunction report (0.1x11 = 1.1, rounded to 1).
[q]  Assumes it takes 3 hours per week per plant to enter monitoring data into records.
[r]  Assumes it takes 1 hour to transmit recorded information.
[s]  Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding. Table 2: Average Annual EPA Burden and Cost  -  NESHAP for Primary Aluminum Reduction Plants (40 CFR Part 63, Subpart LL) (Renewal)

Assumptions:
[a]  Assumes that there is an average of 11 respondents per year subject to the standards and that no additional respondents per year will become subject to the standards. 
[b]  This ICR uses the following average hourly labor rates: $64.80 for managerial (GS-13, Step 5, $40.50 x 1.6), $48.08 (GS-12, Step 1, $30.05 x 1.6) for technical and $26.02 (GS-6, Step 3, $15.6.26 x 1.6) for clerical. These rates are from the Office of Personnel Management (OPM) "2017 General Schedule" which excludes locality rates of pay.
[c]  Assumes that there are no new or reconstructed sources over the three-year period of this ICR. 
[d]  Assumes that all existing sources have design specifications for pitch storage tank controls in place.
[e]  Assumes that it will take 11 hours twice per year to review summary of performance tests requirements to be submitted by all 11 existing plants.
[f]  Assumes that 10 percent of the 11 plants (0.1x11 = 1.1, rounded to 1) will have excess emissions.
[g]  Assumes that the remaining 90 percent of the 11 plants (0.9x11 = 9.9, rounded to 10) will not have excess emissions.
[h]  Assumes that 10 percent of plants per year (0.1x1.1 = 1.1, rounded to 1) will report a malfunction incident.
[i]  Totals have been rounded to 3 significant figures. Figures may not add exactly due to rounding.
