NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal)

1.  Identification of the Information Collection

      1(a)  Title of the Information Collection

NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA)                     (Renewal), EPA ICR Number 1176.11, OMB Control Number 2060-0161.

      1(b)  Short Characterization/Abstract

      The New Source Performance Standards (NSPS) for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) were: proposed on February 18, 1987; promulgated on February 26, 1988; and was last-amended on October 17, 2000.  These regulations apply to each wood heater manufactured either on or after July 1, 1988, or sold at retail either on or after July 1, 1990.  Wood heaters manufactured either on or after July 1, 1990, or sold at retail either on or after July 1, 1992, must meet more stringent emission standards.  Particulate matter (PM) is the pollutant regulated under these standards.  This information is being collected to assure compliance with 40 CFR part 60, subpart AAA.
      
      Two features of this rulemaking which are unique to the NSPS program require emphasis at the outset.  First, these standards were negotiated by representatives of groups affected by the NSPS, including those groups which are burdened by the information collection activities.  None of these activities were judged to be unreasonable by these representatives.  Some of these provisions were recommended by the affected groups as a means of promoting an efficient and smooth running certification and enforcement program.  Second, these regulations established a certification program instead of the usual NSPS requirement that each affected facility demonstrates compliance through New Source Review and testing.  Under this certification program, a single wood heater is tested to demonstrate compliance for an entire model line which could consist of thousands of stoves.  The certification approach significantly reduces the compliance burden, including information collection for the manufacturers of wood heaters.  Because of the potential risks to the environment from the intentional or accidental misuse of the certification approach, there were several safeguards included, some of which entail reporting and recordkeeping requirements.
      
      Under this regulation, wood heater manufacturers, testing laboratories, and retailers are required to submit reports to the Environmental Protection Agency (EPA) and/or to maintain records for demonstrating compliance with the NSPS.
      
      The information supplied by the manufacturer to the Agency is used to: (1) ensure that best demonstrated technology is being applied to reduce emissions from wood heaters; (2) ensure that the wood heater tested for certification purposes is in compliance with the applicable emission standards; (3) provide assurance that non-tested production model heaters have emission performance characteristics similar to tested models; and (4) provide an indicator of continued compliance.
      
      Information supplied to the Agency by testing laboratories is used to grant or deny laboratory accreditation, and to assist in enforcement and compliance activities.  Information requested by the Agency from manufacturers is used to determine compliance with requirements that are based upon volume of production.
      
--------------------------------------------------------------------------------
      Over the next three years, an average of 66 manufacturers, 875 retailers, and 6 certification laboratories, for a total of 947 respondents, are currently subject to the regulations.   It is estimated that no additional sources per year will become subject to these standards.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      "The active (previous) ICR had the following Terms of Clearance (TOC):"
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
            Prior to submission of a request to extend this collection, the Agency should reassess estimates of burden, taking into account recent
--------------------------------------------------------------------------------
            experience with the program.  In particular, the Agency should verify estimates of the number of affected entities and individual models for which information must be submitted.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      EPA has addressed the TOC by updating respondent estimates using the latest data obtained during development of proposed revisions to the NSPS.  These estimates have been verified through consultations with industry.  The comments that EPA received from these consultations are discussed in Section 3(c).
--------------------------------------------------------------------------------
      
	The "Affected Public" are manufacturers of new residential wood heaters, retailers, and accredited testing laboratories.  The "burden" to the "Affected Public" may be found below in Table 1: Annual Respondent Burden and Cost  -  NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (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  -  NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal). 

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

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

--------------------------------------------------------------------------------
      The EPA is charged under Section 111 of the Clean Air Act (CAA), as amended, to establish standards of performance for new stationary sources that reflect: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            . . . application of the best technological system of continuous emissions reduction which (taking into consideration the cost of achieving such emissions reduction, or any non-air quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.  Section 111(a)(l).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
The Agency refers to this charge as selecting the best demonstrated technology (BDT).  Section 111 also requires that the Administrator review and, if appropriate, revise such standards every four years.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      In addition, section 114(a) states that the Administrator may require any owner/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, PM emissions from wood heaters cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare.  Therefore, the NSPS were promulgated for this source category at 40 CFR part 60, subpart AAA.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The control of pollution from new residential wood heaters (i.e., wood stoves) relies on the reduction of particulate matter emissions by proper wood heater design.  A representative unit for each certified model line is tested for particulate emissions.  The manufacturer also conducts periodic quality assurance inspections and emissions tests to ensure that wood heaters manufactured subsequent to the initial certification test continue to comply with the NSPS.  Manufacturers must recertify their wood heater model lines every five years.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The required notifications are used to inform the Agency or delegated authority when a new model line is expected to be tested.  The reviewing authority may then observe the testing operation, if necessary.  Emission test reports are needed as these are the Agency's record of a model line's initial capability to comply with the emission standard, and to serve as a record of the operating conditions under which compliance was achieved.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Adequate recordkeeping and reporting are necessary to ensure compliance with these standards as required by the Clean Air Act.  The information collected from recordkeeping and reporting requirements is also used for targeting inspections and is of sufficient quality to be used as evidence in court.
--------------------------------------------------------------------------------
3.  Non-duplication, Consultations, and Other Collection Criteria
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      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 (FR citation, e.g., 78 FR 33409) on June 4, 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 the EPA Office of Compliance. OTIS is the EPA database for the collection, maintenance, and retrieval of all compliance data.  
      
      Consultations with industry representatives (i.e., respondents) were conducted to determine if there is any way for EPA to reduce the recordkeeping and reporting burden or improve the language in the standard to make it easier to comply.  In developing this ICR, EPA contacted: 1) the Hearth, Patio, Barbeque Association (HPBA), at (916) 536-2390 and 2) Myren Consulting, Incorporated, at (509) 684-1154.  HPBA indicated that there has not been a wholesale change in the number of respondents subject to the standard.  Both contacts believed the estimated number of respondents presented in this ICR (i.e., 66 manufacturers and 6 testing laboratories) appears reasonable, but noted it to be a conservative estimate due to possible industry consolidation.  At this time, the extent of the industry consolidation is unknown.
      
      It is our policy to respond after a thorough review of comments received since the last ICR renewal as well as those submitted in response to the first Federal Register notice.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      3(d)  Effects of Less Frequent Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Less frequent information collection would decrease the margin of assurance that manufacturers are producing residential wood heaters that: (1) pass the initial certification test; and (2) continue to be manufactured in a way that ensures continuous compliance with the emission standards.  If the information required by these standards were collected less   frequently, the likelihood of detecting violations would be reduced.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 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(b)  Information Requested
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      None of these reporting or recordkeeping requirements violate any of the regulations established by OMB at 5 CFR part 1320, section 1320.5.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i)  Data Items
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      In this ICR, all the data that is recorded or reported is required by the NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA).
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      A source must make the following reports: 
--------------------------------------------------------------------------------

                                 Notifications
The reporting requirements for the NSPS were uniquely designed for the manufacturers, testing laboratories, and retailers/distributors of new residential wood heaters.  A special table is attached that describes the requirements in detail.  See below Table A: Respondent Reporting and Recordkeeping, NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal).
See Table A
--------------------------------------------------------------------------------

      A source must keep the following records:

                                Recordkeeping 
The recordkeeping requirements for the NSPS were uniquely designed for the manufacturers, testing laboratories, and retailers/distributors of new residential wood heaters.  A special table is attached that describes the requirements in detail.  See below Table A: Respondent Reporting and Recordkeeping, NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal).
See Table A

Electronic Reporting

      No special automated, mechanical, or technical collection techniques are used to collect information.
      The reports submitted by the manufacturer to EPA either are very voluminous (e.g., the application for model line certificate) or are performed infrequently.  Therefore, the electronic submission of such reports is not considered economically viable.
--------------------------------------------------------------------------------

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

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

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

--------------------------------------------------------------------------------
Manufacturers must obtain a certificate of compliance for each model line of wood heater to be manufactured or sold, and conduct quality assurance activities.

--------------------------------------------------------------------------------
Install, calibrate, maintain, and operate the appropriate equipment and demonstrate their proficiency at performing the required test (emission, burn rate, and air-to-fuel ratio).

--------------------------------------------------------------------------------
Retailers/distributors must maintain sale records of used wood heaters.

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

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

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

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

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

--------------------------------------------------------------------------------
Adjust the existing ways to comply with any previously applicable instructions and requirements.

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

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

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

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

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

--------------------------------------------------------------------------------
      EPA conducts the following activities in connection with the acquisition, analysis, storage, and distribution of the required information.
      
                               Agency Activities
The Agency activities for the NSPS are in response to a uniquely designed rule.  A special table is attached below that describes the requirements in detail.  See below Table B: Agency Activities, NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal).
See Table B
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
	All reports are sent directly to the Agency.  Data obtained during periodic visits by Agency personnel from records maintained by the respondents are tabulated and published for internal Agency use in compliance and enforcement programs.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
	Information contained in the reports is systematically filed at EPA headquarters.  Portions of the data are entered into a special database program maintained exclusively by the agency for later retrieval, study and essential reports.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
	Public access to the wood heater database can be obtained by writing to the Agency.  Reports of wood heaters currently certified are commonly requested by both retailers and the general public.
--------------------------------------------------------------------------------

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

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

--------------------------------------------------------------------------------
      Virtually all of the manufacturers, laboratories, and commercial owners affected by this regulation are considered small businesses, based on the definition used by the Small Business Administration.  Special efforts taken by the Agency to minimize burden to these respondents are summarized elsewhere in this supporting statement.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Since this rule was developed through the regulatory-negotiation process, industry representatives directly participated in the writing of the rule and agreed to make all of the required reports and keep the appropriate records as specified in the rule. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      Additional efforts were taken by the Agency to reduce the burden imposed on the smallest businesses affected by this regulation.  Provisions were included which allow delayed compliance of up to one year for those manufacturers producing fewer than 2,000 wood heaters per year.      In addition, less frequent quality assurance emission audits were required for those manufacturers that produce fewer than 2,500 wood heaters within a model line.  The wood heater standards also allow small manufacturers to purchase a certified design from another manufacturer.  In this case, no certification testing is required.  This provision has significantly reduced the burden associated with certification process for small manufacturers of wood heaters.
--------------------------------------------------------------------------------

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

--------------------------------------------------------------------------------
      The specific frequency for each information collection activity within this request is shown below in Table 1: Annual Respondent Burden and Cost  -  NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
6.  Estimating the Burden and Cost of the Collection
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      Table 1 documents the computation of individual burdens for the recordkeeping and reporting requirements applicable to the industry for the subpart included in this ICR.  The individual burdens are expressed under standardized headings believed to be consistent with the concept of burden under the Paperwork Reduction Act.  Wherever appropriate, specific tasks and major assumptions have been identified.  Responses to this information collection are mandatory.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 11,749 hours (Total Labor Hours from Table 1 below).  These hours are based on Agency studies and background documents from the development of the regulation, Agency knowledge and experience with the NSPS program, the previously approved ICR, and any comments received.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      6(b)  Estimating Respondent Costs
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            (i)  Estimating Labor Costs 
--------------------------------------------------------------------------------
 
--------------------------------------------------------------------------------
      This ICR uses the following labor rates: 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
            Managerial	$123.04 ($111.85+ 110%)   
--------------------------------------------------------------------------------
            Technical	$101.22 ($92.02 + 110%)
--------------------------------------------------------------------------------
            Clerical	$51.18 ($46.53 + 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 testing and labeling.  The Capital/startup costs are one-time costs when a facility becomes subject to the regulation.  Annual operation and maintenance (O&M) costs are the ongoing costs to maintain continuous monitoring systems and other costs such as photocopying and postage.

[a] Each of the 66 manufacturers is assumed to pay $10,000 per certification test for four tests over three years (1.33 tests per year).  1.33 x 66 = 88.  This cost is assumed to include the cost incurred by the laboratory to seal the certified stove.  There are essentially no burden hours associated with this cost.
--------------------------------------------------------------------------------
[b] Total costs of permanent labeling are estimated at $2.00 per stove.  There are essentially no burden hours associated with this cost.  There are an expected 603,354 wood heaters produced by all manufacturers over the three-year ICR period (603,354/3 = 201,118).
--------------------------------------------------------------------------------
[c] Removable labels estimated to cost $0.75 per label.  There are an expected 603,354 wood heaters produced by all manufacturers over the three-year ICR period (603,354/3 = 201,118). 
--------------------------------------------------------------------------------
[d] Assumes an emissions test is performed once every 5,000 units, and since 762 units are produced each year for each model, 0.15 emission tests are performed annually per manufacturer per model.  Each manufacturer has four models; therefore, 0.6 tests per manufacturer will be conducted (0.15 x 4 = 0.6).  There are 66 manufacturers (0.6 x 66  = 40).
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total capital/startup costs for this ICR are $1,733,075.  This is the total of column D in the above table. 
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The total operation and maintenance (O&M) costs for this ICR are $3,000.  This is the total of column G. 
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      The average annual cost for capital/startup and operation and maintenance costs to industry over the next three years of the ICR is estimated to be $1,736,075.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      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 $359,225.
--------------------------------------------------------------------------------

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

		Managerial	$62.27 (GS-13, Step 5, $38.92 + 60%) 
		Technical	$46.21 (GS-12, Step 1, $28.88 + 60%)
		Clerical	$25.01 (GS-6, Step 3, $15.63 + 60%)
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
These rates are from the Office of Personnel Management (OPM), 2013 General Schedule, which excludes locality rates of pay.  The rates have been increased by 60 percent to account for the benefit packages available to government employees.  Details upon which this estimate is based appear below in Table 2: Average Annual EPA Burden and Cost  -  NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (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 947 existing respondents will be subject to the standard.  This total comprises of 66 manufacturers, 875 retailers, and 6 certification laboratories.  It is estimated that no additional respondents per year will become subject.  The overall average number of respondents, as shown in the table below, is 947 per year.
--------------------------------------------------------------------------------

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

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

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

      There is an increase in the total estimated respondent and Agency burdens as currently identified in the OMB Inventory of Approved Burdens.  The change in burdens from the most- recently approved ICR is due to an increase in the number of sources subject to the standard, and is not due to any program changes.  The number of sources has been increased in this ICR to reflect more current information obtained during development of proposed revisions to the NSPS.
      
      There is also an increase in respondent and Agency burden costs from the most-recently approved ICR due to the use of updated labor rates.  This ICR references labor rates from the Bureau of Labor Statistics to calculate respondent burden costs, and references labor rates from OPM to calculate Agency burden costs.
      
      There is an increase in capital/startup and O&M costs as compared to the previous      ICR.  This change also is not due to any program changes.  Similar to the respondent burden adjustments, the change is due to the increased number of sources estimated to be subject to these standards and is not due to any program changes.
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      
--------------------------------------------------------------------------------
      6(g)  Burden Statement
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
      The annual public reporting and recordkeeping burden for this collection of information is estimated to average 42 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.

Assumptions:
[a.] We have assumed an average of 947 respondents will be subject to this rule.  There will be no new additional sources during the next three years of this ICR.  It was necessary to make several assumptions regarding: 1) how wood heater manufacturers would respond to the various alternatives for compliance; and 2) the large variety of wood heater manufacturer sizes and marketing approaches.  Using data from the EPA section 114 survey of manufacturers, the following assumptions were developed for this burden calculation:
     1) 66 woodstove manufacturers;
     2) 4 woodstove models per manufacturer;
     3) 762 woodstoves produced annually for each model by each manufacturer;
     4) 3,047 woodstoves produced annually by each manufacturer; and
     5) 201,118 woodstoves produced each year by all manufacturers.
 [b.] This ICR uses the following labor rates: $101.22 for technical, $123.04 for managerial, and $51.18 for clerical labor.  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.
[c.] We have assumed that the typical manufacturer will require four Phase II certification tests over the three-year ICR period (4/3 = 1.33).
[d.] We have assumed it will take each of the 66 respondents 2 hours to accomplish task 0.5 times per year .
[e.] We have assumed the estimated time required to apply removable labels per wood heater is 30 seconds.
[f.] We have assumed it will take 20 hours to include requisite information in owner's manual.
[g.] We have assumed it will take each of the 66 respondents 2 hours to complete task 0.8 times per year.
[h.] We have assumed that one laboratory will apply for accreditation one time per year.
[i.] We have assumed there will be an average of two notifications per proficiency test due to test cancellation and rescheduling.
[j.] We have assumed each laboratory will conduct proficiency tests.
[k.] We have assumed each laboratory is required to report to EPA regarding changes in the testing schedule or interruptions in testing that last more than 24 hours.  It is assumed that two of these events will occur for each test.
[l.] We have assumed each laboratory is expected to spend four hours per week to update and maintain records on certification tests.
[m.] We have assumed that each respondent will take 1 hour to complete task 1.33 times per year.
n. We have assumed that 762 units per model per year are produced, and that one out of every 150 units undergoes a parameter inspection.  Thus, a parameter inspection will occur approximately five times per year per manufacturer model.  Since each manufacturer has four models, 20 parameter inspections will be conducted annually by each manufacturer (5*4 = 20).
[o.] We have assumed there will be no additional burden because manufacturers already keep track of sales data for marketing purposes and payment of income taxes.
[p.] We have assumed one report will be filed by each manufacturer annually.
[q]. We have assumed it will take eight hours for each respondent to complete the task.
[r.] We have assumed that one-tenth of the estimated 8,751 wood heater retailers will buy and sell used wood stoves.  We assume each of these 875 retailers will purchase 4 used stoves per year and will spend 6 minutes per purchase maintaining records of each wood heater purchase.Table 2: Average Annual EPA Burden and Cost  -  NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Renewal)

Assumptions:
[a.] We have assumed an average of 947 respondents will be subject to this rule.  There will be no new additional sources during the next three years of this ICR.  It was necessary to make several assumptions regarding: 1) how wood heater manufacturers would respond to the various alternatives for compliance; and 2) the large variety of wood heater manufacturer sizes and marketing approaches.  Using data from the EPA section 114 survey of manufacturers, the following assumptions were developed for this burden calculation:
     1) 66 woodstove manufacturers;
     2) 4 woodstove models per manufacturer;
     3) 762 woodstoves produced annually for each model by each manufacturer;
     4) 3,047 woodstoves produced annually by each manufacturer; and
     5) 201,118 woodstoves produced each year by all manufacturers.
[b.] This ICR uses the following labor rates: $46.21 for technical, $62.27 for managerial, and $25.01 for clerical labor.  These rates are from the Office of Personnel Management (OPM) 2013 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.
[c.] We have assumed that 10 percent of wood heater manufacturers will request a determination of applicability once per year (0.1*66 = 7, after rounding).
[d.] We have assumed each manufacturer will require four EPA certification tests over the next three years for an average of 1.33 certification tests per manufacturer per year.
[e.] We have assumed that there will be 1.33 certifications per manufacturer per year, and that EPA will send an observer to one out of every ten certification tests.
[f.] We have assumed that the typical manufacturer will require four Phase II certification tests over the three-year period.  Thus, four notices in three years equals to 1.33 notices per year (4/3 = 1.33).
[g.] We have assumed biennial reporting occur 0.50 occurrences per year.
[h.] We have assumed one new lab will apply for accreditation each year.
[i.] We have assumed that for labs to receive accreditation, each laboratory will be required to perform a proficiency test one time during each year.
[j.] We have assumed there will be an average of two notifications per proficiency test due to test cancellation and rescheduling. We also have assumed it will take 25 hours to complete the new lab accreditation.
[k.] Laboratory proficiency test reports will consist of four parts.  The first part, test design and implementation, is assumed to require 80 hours once per year to evaluate.  The second part, test observation, assumes that EPA will send an observer to one-fourth of all tests.  The third part, review of test reports, assumes that each laboratory will submit a report and that each report will require 20 hours to review.  The fourth part, analysis and conclusions, is assumed to take 40 hours once per year.
[l.] Random compliance audits to inspect wood heater parameters are expected to be conducted on one-quarter of each manufacturer's model lines per year.
