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 1767.07, OMB Control Number 2060-0360. 

      1(b)  Short Characterization/Abstract		

      The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Primary Aluminum Reduction Plants were proposed on September 26, 1996, promulgated on October 7, 1997, and most-recently amended on November 2, 2005.  These regulations apply to owner or operator of the affected facilities which include new or existing potlines, paste production plants, or anode bake furnaces associated with primary aluminum production and located at a major source, and for each new pitch storage tank associated with 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 of these measurements, and retain the file for at least five years following the date of such measurements, maintenance reports, and records.  All reports are sent to the delegated state or local authority.   In the event that there is no such delegated authority, the reports are sent directly to the U.S. Environmental Protection Agency (EPA) regional office.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Over the next three years, an average of 16 respondents per year will be subject to these standards, and no additional respondents per year will become subject to these same standards.  However, we expect that one existing source per year will undergo reconstruction. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The Office of Management and Budget (OMB) approved the currently active ICR without any "Terms of Clearance."
--------------------------------------------------------------------------------
      
	The 16 major source facilities in the United States, which are the respondents in this ICR, are publicly-owned and operated by primary aluminum reduction plants.  None of the facilities are owned by either state, local, tribal agencies, or the Federal government.  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 "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). 

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

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

--------------------------------------------------------------------------------
      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, hydrogen fluoride (HF), polycyclic organic matter (POM), and particulate matter smaller than 10 microns in diameter (PM10) 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 where promulgated in accordance with the Clean Air Act.  The collected information is also used for targeting inspections and as evidence in legal proceedings.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Performance tests are required in order to determine an affected facility's initial capability to comply with the emission standards. Continuous emission monitors are used to ensure compliance with the standard at all times. During the performance test a record of the operating parameters under which compliance was achieved may be recorded and used to determine compliance in place of a continuous emission monitor.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The notifications required in 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 are 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 (78 FR 35023) on June 11, 2013.  No comments were received on the burden published in the Federal Register.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(c)  Consultations
      
--------------------------------------------------------------------------------
      The Agency's industry experts have been consulted, and the Agency's internal data sources and projections of industry growth over the next three years have been considered.  The primary source of information as reported by industry, in compliance with the recordkeeping and reporting provisions in the standard, is the Online Tracking Information System (OTIS) which is operated and maintained by EPA's Office of Compliance.  OTIS is EPA's database for the collection, maintenance, and retrieval of all compliance data.  The growth rate for the industry is based on our consultations with the Agency's internal industry experts. 
      Industry trade associations and other interested parties were provided an opportunity to comment on the burden associated with the standards as they were being developed and the standards have been reviewed previously to determine the minimum information needed for compliance purposes.  In developing this ICR, we contacted both the Aluminum Association, at (703) 358-2960, and the South East Center for Aluminum Technology, at (859) 514-4989.
      
      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 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.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 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 the standard do not include sensitive questions.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
4.  The Respondents and the Information Requested

--------------------------------------------------------------------------------
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.  At this time, it is estimated that approximately 50 percent of the respondents use electronic reporting.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (ii)  Respondent Activities	
--------------------------------------------------------------------------------


--------------------------------------------------------------------------------
Respondent Activities

--------------------------------------------------------------------------------
Read instructions.

--------------------------------------------------------------------------------
Install, calibrate, maintain, and operate CMS for opacity, or for pressure drop and liquid supply pressure for dry alumina scrubbers, dry coke scrubbers, wet scrubbers, electrostatic precipitators and wet roof scrubbers.  If approved by the appropriate regulatory agency, a respondent may install, calibrate, maintain, and operate an HF CMS for the monitoring of TF secondary emissions as an alternative method.

--------------------------------------------------------------------------------
Perform initial performance test, Reference Method 1, 2, 3, 13A or 13B, 14 or 14A, 315 tests, and repeat performance tests if necessary.

--------------------------------------------------------------------------------
Write the notifications and reports listed above.

--------------------------------------------------------------------------------
Enter information required to be recorded above.

--------------------------------------------------------------------------------
Submit the required reports developing, acquiring, installing, and utilizing technology and systems for the purpose of collecting, validating, and verifying information.

--------------------------------------------------------------------------------
Develop, acquire, install, and utilize technology and systems for the purpose of processing and maintaining information.

--------------------------------------------------------------------------------
Develop, acquire, install, and utilize technology and systems for the purpose of disclosing and providing information.

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

--------------------------------------------------------------------------------
Transmit, or otherwise disclose the information.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Currently sources are using monitoring and reporting equipment that provide parameter data in an automated way e.g., continuous parameter monitoring system.  Although personnel at the source still need to evaluate the data, this type of monitoring equipment has significantly reduced the burden associated with monitoring and recordkeeping. 
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      5(a)  Agency Activities  
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      EPA conducts the following activities in connection with the acquisition, analysis, storage, and distribution of the required information.
--------------------------------------------------------------------------------


--------------------------------------------------------------------------------
Agency Activities

--------------------------------------------------------------------------------
Review notifications and reports, including performance test reports, and excess emissions reports, required to be submitted by industry.

--------------------------------------------------------------------------------
Audit facility records.

--------------------------------------------------------------------------------
Input, analyze, and maintain data in the Online Tracking Information System (OTIS). 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(b)  Collection Methodology and Management
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Following notification of startup, the reviewing authority could inspect the source          to determine whether the pollution control devices are properly installed and operated.  Performance test reports are used by the Agency to discern a source's initial capability to  comply with the emission standard, 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 entered into OTIS which is operated and maintained by EPA's Office of Compliance.  OTIS is EPA's database for the collection, maintenance, and retrieval of compliance data for approximately 125,000 industrial and government-owned facilities.  EPA uses the OTIS for tracking air pollution compliance and enforcement by local and state regulatory agencies, EPA regional offices and EPA headquarters.  EPA and its delegated Authorities can edit, store, retrieve and analyze the data.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
       The records required by this regulation must be retained by the owner/operator for five years.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      A majority of the respondents are large entities (i.e., large businesses).  However, the impact on small entities (i.e., small businesses) was taken into consideration during the development of the regulation.  Due to technical considerations involving the process operations and the types of control equipment employed, the recordkeeping and reporting requirements are the same for both small and large entities.  The Agency considers these to be the minimum requirements needed to ensure compliance and, therefore, cannot reduce them further for small entities.  To the extent that larger businesses can use economies of scale to reduce their burden, the overall burden will be reduced.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      5(d)  Collection Schedule
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown in below 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 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 80,023 (Total Labor Hours from Table 1 below).  These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the 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	$123.04 ($58.59+ 110%)   
--------------------------------------------------------------------------------
            Technical	$101.22 ($48.20 + 110%)
--------------------------------------------------------------------------------
            Clerical	$51.18 ($24.37 + 110%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the United States Department of Labor, Bureau of Labor Statistics, March 2013, "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 standards are both labor costs which are addressed elsewhere in this ICR and the costs associated with continuous monitoring.  The capital/startup costs are one-time costs when a facility becomes subject to the regulation.  The annual operation and maintenance costs are the ongoing costs to maintain the 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 $91,348.  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 $91,348.   
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 $11,277.  
--------------------------------------------------------------------------------

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

      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 16 existing respondents will be subject to the standard.  It is estimated that no additional   respondents per year will become subject, but one existing respondent per year will reconstruct its facility.  The overall average number of respondents, as shown in the table below, is 16 per year.  
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The number of Total Annual Responses is 40.  
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total annual labor costs are $7,827,639 (rounded).  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).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      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 and summarized below in Tables 1 and 2, respectively.  
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The total annual labor hours are 80,023 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).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Furthermore, the annual public reporting and recordkeeping burden for this collection of information is estimated to average 2,000 hours per response.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The total annual capital/startup and O&M costs to the regulated entity are $91,348.  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 250 labor hours at a cost of $11,277.  See below 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 no significant change in burden in this ICR compared to the previous ICR.  This is due to two considerations: 1) the regulations have not changed over the past three years, and are not anticipated to change over the next three years; and 2) the growth rate for the industry is very low, negative or non-existent, so there is no significant change in the overall burden.  The apparent decrease of 375 hours in respondent burden is due to a mathematical correction.  The previous ICR incorrectly summed the number of recordkeeping hours.  In addition, there is a small increase in respondent cost due to an update in labor rates. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      6(g)  Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 2,000 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-2013-0348.

Assumptions:
[a]  This ICR uses the following labor rates: $123.04 for managerial labor, $101.22 for technical labor, and $51.18 for clerical labor. These rates are from the U.S. Department of Labor, Bureau of Labor Statistics, March 2013. The rates have been increased by 110 percent to account for overhead.
[b]  Assumes that one plant per year will have to comply with initial rule requirements due to a reconstruction of an affected facility (i.e., pitch storage tank). It is assumed that the plant has a startup, shutdown, and malfunction plan in place.
[c]  Assumes it takes 100 hours each for Method 13 and Method 315 for primary controls of potlines and bake furnaces.
[d]  Assumes 59 Method 13 tests and 22 Method 315 tests will be conducted each year (primary control systems) for a total of 81 tests for 16 respondents (81/16 = 5.1 per respondent).
[e]  Assumes that there are 16 primary aluminum plants subject to this standard.
[f]  Assumes it takes 200 hours for Method 13/14 for secondary emissions from potlines.
[g]  Assumes that 12 potlines must perform manual sampling as a result of the NESHAP. Testing was already required by the states for other potlines.
[h]  Assumes it takes 40 hours for testing of similar potlines (CEM or Alcan cassette).
i  Assumes that 24 potlines will be monitored under the alternative monitoring provisions for similar potlines. This is 18 per respondent (24x12/16 = 18).
[j]  Assumes it takes 200 hours for a Method 315 test for secondary emissions.
[k]  Assumes that a total of 8 Soderberg potlines at two plants. This is 16 per respondent (8x4/2 = 16).
[l]  Assumes that two Soderberg plants will conduct quarterly performance tests.
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 (0.1x16 = 1.6).
[o]  Assumes that 90 percent meet the standard (0.9x16 = 14.4).
[p]  Assumes that 10 percent must file startup, shutdown, malfunction report (0.1x16 = 1.6).
[q]  Assumes it takes 3 hours per week per plant to enter monitoring data into records.
[r]  Assumes it takes 15 minutes to transmit recorded information.

Assumptions:
[a]  This ICR uses the following average hourly labor rates: $62.27 for managerial (GS-13, Step 5, $38.92 x 1.6), $46.21 (GS-12, Step 1, $28.88 x 1.6) for technical and $25.01 (GS-6, Step 3, $15.63 x 1.6) for clerical. These rates are from the Office of Personnel Management (OPM) "2013 General Schedule" which excludes locality rates of pay.
[b]  Assumes that one plant per year over the next three years will install a new or reconstructed pitch storage tank.
[c]  Assumes that EPA/state personnel will review summary of performance tests requirements to be submitted by all 16 existing plants on an annual basis for purposes of calculating the burden. However, plants are expected to submit performance test results with the semiannual reports.
[d]  Assumes that 10 percent of the 16 plants (0.1x16 = 1.6) will have excess emissions.
[e]  Assumes that the remaining 90 percent of the 16 plants (0.9x16 = 14.4) will not have excess emissions.
[f]  Assumes that 10 percent of plants per year (0.1x1.6 = 1.6) will report a startup, shutdown, malfunction incident.
