SUPPORTING STATEMENT
                     NSPS for New Residential Wood Heaters
                   (40 CFR Part 60, Subpart AAA) (Revision)
                                       
PART A
1.0	Identification of the Information Collection
(a)	Title of the Information Collection.
   	The title of the Information Collection Request (ICR) is NSPS for New Residential Wood Heaters (40 CFR Part 60, Subpart AAA) (Revision), U.S. Environmental Protection Agency (EPA) tracking number 1176.12, Office of Management and Budget (OMB) Control Number 2060-0161.
(b)	Short Characterization/Abstract.
	This ICR covers information collection requirements in the final revisions of the New Source Performance Standards (NSPS) for new residential wood heaters (40 CFR part 60, subpart AAA (subpart AAA)). The information collected will be used by the EPA and delegated state and local agencies to determine the compliance status of sources subject to the rule. A wood heater is defined as an enclosed, wood burning appliance capable of and intended for residential or space heating and domestic water heating. Unless otherwise specified, these devices include, but are not limited to, adjustable burn rate wood heaters, single burn rate wood heaters and pellet stoves.
	One feature of the NSPS requires emphasis at the outset. That is, the requirements of 
subpart AAA establish a certification program instead of the usual NSPS requirements where each affected facility is required to demonstrate compliance through performance testing. Under the subpart AAA-required certification program, a single wood heater is tested to demonstrate compliance with particulate matter (PM) emission limits for an entire model line which could consist of thousands of stoves. The use of a certification approach significantly reduces the compliance burden, including information collection, for the manufacturers of wood heating appliances. In order to minimize risks to the environment from intentional or accidental misuse of the certification approach, subpart AAA includes several safeguards, some of which entail reporting and recordkeeping. 
      There are approximately 66 manufacturers and 6 laboratories (inclusive of both test labs and third-party certifiers) that would be subject to the final amended subpart AAA. Under subpart AAA, wood heater manufacturers, testing laboratories and third-party certifiers are required to submit reports to the EPA and to maintain records for demonstrating compliance with the NSPS. The information supplied by the manufacturer to the EPA is used to: (1) ensure that best system of emission reduction 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 EPA by testing laboratories and third-party certifiers is used to grant or deny laboratory accreditation, assure continued test lab proficiency and to assist in enforcement and compliance activities. 
      Subpart AAA does not require any reporting or recordkeeping requirements on wood heater owners or operators. However, the final rule specifies a list of prohibited fuel types and prohibited operations as well as good operating and good burning practices (which are required to be included in the owner's manual for certified wood heater models) that owners and operators are directed to follow when installing and operating their wood stoves. 
      The phased implementation schedule of the final rule along with the two-step PM emission standards approach (with phased compliance dates) results in differing recordkeeping and reporting impacts. For purposes of the supporting statement, we refer to these steps as Step 1 and Step 2. The compliance date for meeting Step 1 emission standards provided in the rule occurs in 2015, and the compliance date for meeting Step 2 emission standards provided in the rule occurs in 2020. The recordkeeping and reporting burden estimates provided during this ICR period are for years 2015 to 2017. The recordkeeping and reporting burden cost estimates as a result of the subpart AAA final amendments for years 2018 to 2020 are presented in a memo to the docket. The recordkeeping and reporting respondent burden estimates included in this supporting statement for years 2015 to 2017 and the burden estimates outlined in the memo for years 2018 to 2020 are both included in cost impacts estimates included in a memo in the docket for the final rule.
      You can find the estimated burden to the "Affected Public" listed in Table 1, Three-Year and Annual Respondent Burden and Cost of Reporting and Recordkeeping Requirements of the Final Amended Rule. The federal government burden associated with the review of reports submitted by the respondents is shown below in Table 2, Three-Year and Annual Burden and Cost to the Federal Government of the Final Amended Rule. (Tables 1 and 2 are located at the end of this supporting statement.) We do not anticipate any reporting or recordkeeping burden for state, local or tribal entities because we have only delegated enforcement of the standards for new residential wood heaters sold or operated in their region. Under subpart AAA, partial delegations shall not include:
      (1) Decisions on certification;
      (2) Revocation of certification;
      (3) Standards;
      (4) Test methods;
      (5) Laboratory and third-party certifier approvals and revocations;
      (6) Enforcing provisions governing content of owner's manuals; and
      (7) Hearings and appeals procedures.
	The information collection requirements for new sources subject to the NSPS for Residential Wood Heaters are listed in Attachment 1.
2.	Need For and Use of the Collection
(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 system of emission reduction which (taking into consideration the cost of achieving such reduction and 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 system of emission reduction." Section 111 also requires that the Administrator review and, if appropriate, revise such standards every 8 years. In the Administrator's judgment, pollutant emissions from wood heaters cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare. Therefore, the NSPS was promulgated for this source category at 40 CFR part 60, subpart AAA.
	The records and reports required under the amended subpart AAA are necessary for the Administrator to confirm the compliance status of new residential wood heaters sold in the United States. These recordkeeping and reporting requirements are authorized by CAA section 114.  
(b)	Practical Utility/Users of the Data.
	The control of pollution from new residential wood heaters relies on the reduction of particulate matter emissions by proper wood heater design. A representative unit for each model line is subjected to a certification test for particulate matter emissions for a range of operating conditions. The manufacturer also contracts with a third-party certifier, which reviews the test reports and quality assurance (QA) plan, and conducts periodic QA audits to ensure that wood heaters manufactured subsequent to the initial certification test continue to comply with the NSPS. Manufacturers must renew or recertify their wood heater model lines every 5 years or when they make changes to the model line that would exceed specified parameters.
      The required certification test notification is used to inform the EPA when a new model line is expected to be tested. The EPA may then observe the testing, if desired. Emission test reports are needed as these are the EPA's record of a model line's initial capability to comply with the emission standards, and serve as a record of the operating conditions under which compliance was achieved. The EPA compliance audit tests and QA annual audit reports are necessary to ensure continued compliance with emissions standards.
      Adequate recordkeeping and reporting are necessary to ensure compliance with these standards as required by the CAA. 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
(a)	Non-duplication.
      A computer search of the EPA's ongoing ICRs revealed no duplication of information-gathering efforts. The information-gathered under the final amended subpart AAA will replace the information gathered under subpart AAA prior to being amended.
      Similar requirements to this amended NSPS are found in the requirements to 40 CFR part 60, subpart QQQQ, the NSPS for New Residential Hydronic Heaters and Forced-Air Furnaces. Subpart QQQQ has a separate ICR undergoing OMB review. Although the requirements are similar, they are not duplicative because they apply to separate groups of appliances and their associated manufacturers. In the case of test laboratories and third-party certifiers, similar test accreditation requirements are found in both subparts, but each has different test methods. Therefore, the requirements under each of these subparts are not duplicative because separate accreditation is required for each test method.
(b)	Public Notice Required Prior to ICR Submission to OMB.
	The preamble to the proposed rule (79 FR 6330, February 3, 2014) provided public notice of the proposed ICR. The EPA considered comments (see Docket No. EPA-HQ-OAR-2009-0734) when preparing this revised ICR. The preamble to the final rule provides public notice on this revised ICR.
(c)	Consultations.
      The final rule amendments were developed using information obtained during extensive consultation with individual companies, trade associations and state agencies. Several of the key non-EPA persons consulted on the information collection activities are identified in Table 3. Additional meetings and contacts are documented in the project docket for this final rule, Docket No. EPA-HQ-OAR-2009-0734.

(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.
(e)	General Guidelines. 
      None of the guidelines in 5 CFR 1320.6 is being exceeded, with the exception of the requirement to retain records for 5 years (which exceeds the guideline requirement that records not be required to be retained for more than 3 years). The basis for the 5-year record retention is because the required emission standard model certifications are valid for 5 years prior to the need for renewal or recertification. During this time, the EPA needs to require the retention of model certification tests and QA compliance documentation to support initial and continued compliance with model certifications (e.g., certification tests, QA emissions tests, QA audit reports, biennial reports). 
(f)	Confidentiality.
	All information submitted to the EPA for which a claim of confidentiality is made will be safeguarded according to the EPA regulations set forth in 40 CFR 2.201 et seq., Chapter 1, Part 2, Subpart B -- Confidentiality of Business Information.
(g) 	Sensitive Questions. 
	This section is not applicable because this ICR does not involve matters of a sensitive nature.
4.	The Respondents and the Information Requested
(a)	Respondents/NAICS Codes.
      Potential respondents under subpart AAA are manufacturers of new residential wood stoves and pellet heaters. The North American Industry Classification System (NAICS) code for residential wood heating manufacturing facilities is 333414, Heating Equipment (Except for Warm Air Furnace Manufacturing). Subpart AAA also applies to laboratories that conduct or plan to conduct wood heater certification tests (referred herein as testing labs) and laboratories that plan to become third-party certifiers (referred herein as third-party certifiers) for manufacturers. The NAICS code for testing laboratories is 541380. 
(b)	Information Requested.
      (i) Data Items, Including Recordkeeping Requirements. In this ICR, all the data recorded or reported is required by the NSPS for New Residential Wood Heaters (40 CFR part 60, subpart AAA). The reporting requirements for NSPS subpart AAA were uniquely designed for the manufacturers, third-party certifiers and testing laboratories. The records required by this regulation must be retained by the manufacturer, third-party certifier and/or test laboratory for 5 years. A special table is attached that describes the reporting and recordkeeping requirements. See Attachment 1.
      (ii) Respondent Activities. The respondent activities that will be required by the final amended New Residential Wood Heater NSPS are identified in Table 1 (located at the end of this supporting statement) and introduced in section 6(a).
5.	The Information Collected - Agency Activities, Collection Methodology and Information Management
(a)	Agency Activities.
	Attachment 2 is a summary of the reporting and recordkeeping requirements for the federal government. The EPA activities associated with the final amended New Residential Wood Heater NSPS are provided in Table 2 (located at the end of this supporting statement) and are introduced in section 6(c).
(b)	Collection Methodology and Management.
      All reports are sent directly to the EPA electronically. Data obtained from reports submitted and records maintained by the respondents will be used in compliance and enforcement programs. Portions of the data obtained will be entered into a special database program maintained exclusively by the EPA and some of the data will be made available to the public on an EPA website. 
      The EPA provides public access to the list of certified appliances and their emissions ratings on line at http://www.epa.gov/compliance/resources/publications/monitoring/caa/woodstoves/certifiedwood.pdf.

(c)	Small Entity Flexibility.
      Most of the manufacturers, laboratories and commercial owners affected by the final amended subpart AAA are considered small businesses based on the definition used by the Small Business Administration. Additional efforts were taken by the EPA to reduce the burden imposed on the smallest businesses affected by this regulation. For heaters/stoves with EPA certification currently in effect with Step 1 emission standards, we are giving conditional, automatic certification approval until the Step 2 emission standards effective date (2020). Allowing conditional, automatic certification of those heaters/stoves with compliant certifications and including phased compliance dates in the final rule allows additional time for sources to come into compliance and helps reduce the burden on small businesses by spreading out research and development (R&D) costs over several years. We have also retained certification waiver provisions in the existing subpart AAA because they reduce the need for sources to re-test already certified models under qualifying conditions and reduce the burden associated with the certification process for small manufacturers of wood heaters. The final rule also includes changes to the QA program requirements that align better with existing safety QA procedures, thus eliminating duplicative procedures. Lastly, we have also deferred the requirement for (1) EPA-accredited test labs to be accredited under subpart AAA for three years after the effective date of the rule and (2) non EPA-accredited test labs to be accredited under subpart AAA for six months after the effective date of the rule. 
(d)	Collection Schedule.
	The specific frequency for each information collection activity within this request is shown in Table 1 for the residential wood heater source category, which is located at the end of this supporting statement.
6.	Estimating the Burden and Cost of the Collection
(a) 	Estimating Respondent Burden.
	The annual recordkeeping and reporting respondent burden estimates for the New Residential Wood Heater NSPS final amended rule are shown in Table 1, located at the end of this section. These numbers were derived from estimates based on the EPA's experience with implementing existing subpart AAA and other standards. 

(b)	Estimating Respondent Costs.
	(i) Estimating Labor Costs. Loaded labor rates have been calculated for 2013. We used May 2013 labor rates from the Bureau of Labor Statistics for the Ventilation, Heating, Air-Conditioning and Commercial Refrigeration Equipment Manufacturing (NAICS 333400). Loading factors (i.e., fringe benefits and overhead rates) were calculated using methodologies referenced in promulgated regulations and their accompanying ICRs, particularly those used in New Source Review (NSR) regulations. Fringe benefits are calculated as 29 percent of hourly earnings, and overhead is calculated using a standard 110 percent above hourly earnings. Table 4 presents the labor rates used in the cost analysis.

                                                                        $49.36 
                                       
      (ii) Estimating Capital and Operations and Maintenance (O&M) Costs. In this section we provide estimated capital costs and one-time start-up costs associated with complying with the NSPS over the three-year ICR clearance period. These costs are summarized in Table 5 at the end of this section. Estimated capital costs included in Table 5 include fixed capital cost estimates provided by an analysis prepared by Ferguson, Andors & Company for the Hearth, Patio and Barbecue Association. See the manufacturer costs impacts memo and the unit cost memo for more information on assumptions used in this section. Note that these cost impacts differ from ICR 1176.11 based on new information on the structure of the industry and the final amendments made to subpart AAA that would result in additional expenses during the three-year ICR clearance period in order for all models to comply with the final standards.
      As discussed in the manufacturer cost impacts memo, we estimate that there are currently 125 model lines of adjustable burn rate stoves produced by 34 manufacturers, 20 model lines of single burn rate stoves produced by 3 manufacturers and 125 model lines of pellet stoves produced by 29 manufacturers. We assume that 90% of existing adjustable burn rate models (0.9 X 125 models = 112.5)(34 manufacturers), 25% of existing pellet stove models (0.25 X 125 models = 31.25)(29 manufacturers), and 0% of single burn rate stove models (0 X 20 = 0) (3 manufacturers) will meet EPA criteria as meeting Step 1 emission standards, and therefore will not need to test or apply for certifications during the three-year ICR period (2015-2017). We assume that a like number of models to replace existing models that currently do not meet the Step 1 emission standards (approximately 126 models) will be developed/tested and will apply to certify to meet the Step 1 emission standards or Step 2 emission standards during the three-year ICR period (2015-2017) at a cost of $16,750 per test (includes EPA-required testing ($11,000), confirmation safety testing or full safety testing ($5,000), and shipping of prototype(s)($750) costs). 
      The amended NSPS requires a permanent label on each wood heater model. To estimate the capital costs of the permanent label, we assumed the capital costs to be $400 per model certified (including those that receive conditional certification) and that all new models produced by all manufacturers to meet subpart AAA will have a permanent label affixed. These costs are consistent with cost estimates provided in Ferguson's analysis. 
      The amended NSPS requires that each wood heater offered for sale by a commercial owner be accompanied by an owner's manual that contains specified installation and operation and maintenance information required to be followed to minimize emissions. We have assumed an average fixed cost of $2,250 for owner's manual (revised or new, possibly bilingual) per model, assuming 125 pellet stoves, 44 adjustable burn rate stoves and 20 single burn rate stove owner's manuals will need to be developed/revised to include subpart AAA requirements. These costs are consistent with cost estimates provided in an analysis prepared for the Hearth, Patio & Barbecue Association (HPBA) by Ferguson, Andors & Company.
      The 1988 requirements for manufacturer QA programs are strengthened in the revised rule by requiring the manufacturer to contract with a third-party certifier to conduct QA audits. The third-party certifier will be required to conduct regular (at least annual), unannounced audits (and prepare a report for submission to the EPA) of each certified model line to ensure that the manufacturer's QA plan is implemented properly. For purposes of this ICR, we assume that the contracted third-party certifier will require one QA performance test and one QA audit for each of the wood stove manufacturers (66 manufacturers) under the QA program between 2015 and 2017.
      Another category of capital costs includes costs that would be incurred if the EPA requests a compliance audit, which would be infrequent and sporadic. We assume that there would only be one EPA compliance audit during the three-year ICR period (2015-2017) that would affect one manufacturer. For purposes of estimating the capital costs that would be incurred by an EPA compliance audit, we assume the cost of one appliance (based on the average of two appliances: 1 adjustable burn rate model ($848 each) and 1 pellet ($1,281 each) stove model) plus $16,750 for testing (includes EPA-required testing ($11,000), confirmation safety testing or full safety testing ($5,000), and shipping of prototype(s) ($750) costs). 
      The last category of capital costs relates to ISO accreditation costs for test labs and third-party certifiers seeking accreditation (assuming a cost of $75,000/accreditation). Table 5 presents the estimated capital/start-up costs for the three-year clearance period (2015-2017).

[a] Models certified by testing per manufacturer: Assumes that 90% of existing adjustable burn rate models (.9 X 125 models = 112.5)(34 manufacturers), 25% of existing pellet stove models (.25 X 125 models=31.25)(29 manufacturers), and 0% of single burn rate stove models (0 X 20 = 0) (3 manufacturers) will not need to test and apply to certify to meet emission standards during the three-year ICR period (2015-2017). We assume that manufacturers will test (at a cost of $16,750 per test (includes EPA testing ($11,000), confirmation safety testing or full safety testing ($5,000), and shipping of prototype(s)($750) costs)) and apply to meet emission standards for 126 models during the three-year ICR period (2015-2017) in order to replace old models that will not meet the Step 1 emission standards.
[b] Total costs of permanent labels are estimated to be $400 per model. We estimate that there will be 270 certified models produced by all manufacturers (66 manufacturers) during the period covered by this ICR (2015-2017) that would be subject to permanent labeling requirements.
[c] Assumes that there will be 66 QA performance tests (at a cost of $16,750 per test (includes EPA testing ($11,000), confirmation safety testing or full safety testing ($5,000), and shipping of prototype(s)($750) costs)) under the QA program during the three-year period covered by this ICR (2015-2017). We assume that each of the 66 manufacturers will be required to test one model under their QA program between 2015 and 2017.
[d] Assumes that there will be EPA compliance audit testing for one model affecting one manufacturer during the period covered by this ICR (2015-2017). Costs for EPA compliance audit testing of one model assumes the cost of one appliance (based on the average cost of two models: 1 adjustable burn rate model ($848 each) and 1 pellet ($1,281 each) stove model)) plus $16,750 for the test (includes EPA testing ($11,000), confirmation safety testing or full safety testing ($5,000), and shipping of prototype(s) ($750) costs).
[e] Assumes an average fixed cost of $2,250 for owner's manual (revised or new, possibly bilingual) per model (270 models) that will need to be developed/revised to include subpart AAA requirements.
[f] Assumes all test labs will be ISO accredited (that are going to choose be accredited) before 2018, a total of four labs between 2015 and 2017 and 0 occurrences between 2018 and 2020. We assume an average cost to obtain ISO accreditation is $75,000 based costs estimates provided by manufacturers.
[g] Assumes all third-party certifiers will be ISO accredited (that are going to choose to be accredited) before 2018, a total of two third-party certifiers between 2015 and 2017 and 0 occurrences between 2018 and 2020. We assume an average cost to obtain ISO accreditation is $75,000 based on cost estimates provided by manufacturers.

	(iii) Annualizing Capital Costs. The total annual capital/start-up costs are estimated to average $1,466,438 over the period of this ICR (2015-2017).
(c)	Estimating Agency Burden and Cost.
	The major costs to the EPA are those costs associated with reviewing applications for model certifications, testing lab and third-party certifier accreditations, and ongoing compliance verification QA functions. This is consistent with the overall EPA compliance and enforcement program, which 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 3 years of the ICR is estimated to be $32,603. See Table 2, located at the end of this supporting statement.
	The agency labor rates are from the Office of Personnel Management (OPM) 2014 General Schedule which excludes locality rates of pay. These rates can be obtained from Salary Table 2014-GS available on the OPM website, http://www.opm.gov/policy-data-oversight/pay-leave/salaries-wages/salary-tables/pdf/2014/salhrl.pdf.  The government employee labor rates are $15.78/hour for clerical (GS-6, Step 3), $29.17 for technical (GS-12, Step 1) and $39.31/hr for management (GS-13, Step 5). These rates were increased by 60 percent to include fringe benefits and overhead. The fully-burdened wage rates used to represent agency labor costs are: clerical at $25.25, technical at $46.67 and management at $62.90.
(d)	Estimating the Respondent Universe and Total Burden and Costs.
      Subpart AAA requires wood heater manufacturers, test laboratories and third-party certifiers to submit reports and/or to maintain records for demonstrating and documenting compliance with the NSPS. A third-party certification process is required under subpart AAA. Under this process, for all heaters/stoves subject to subpart AAA, after testing is completed by an approved test laboratory, a certification of conformity with the particulate matter emissions standards must be issued by a third-party certifier with whom the manufacturer has entered into contract for certification services. In order to avoid the potential for manufacturer model certification delays (and the potential for lost revenues), subpart AAA allows for automatic certification for wood heaters that meet Step 1 emission standards until the Step 2 emission standard compliance date (2020).
      The third-party certifier is an independent third-party that is ISO accredited to perform certifications, inspections and audits by an accreditation body. Accredited third-party certifiers under subpart AAA must maintain records of all certification tests, QA program inspections and QA audit performance tests. The third-party certifier can certify conformity if the emission tests have been conducted per the appropriate guidelines; the test report is complete and accurate; the instrumentation used for the test was properly calibrated; the test report shows that the representative affected wood heater meets the applicable emission limits; and the QA plan prepared by the manufacturer is adequate to ensure that units within the model line will be similar in all material respects that would affect emissions to the wood heater submitted for certification testing. The third-party certifier is also required to conduct regular (at least annual) unannounced audits to ensure that the manufacturer's QA plan is being implemented and must prepare a report for each audit that fully documents the results of the audit. The manufacturer must include in its contract with the third-party certifier the authorization and requirement to submit all such reports to the Administrator. The ISO accreditation and approval to be third-party certifiers will not be required until 6 months after the effective date of the rule. We have assumed that of the 6 labs, 2 will have ISO accreditation as third-party certifiers by the effective date of the final amended rule and 2 will choose to obtain ISO accreditation as third-party certifiers during the period covered by this ICR (2015-2017).
      Test laboratories that want to become approved test laboratories to conduct NSPS certification testing will need to apply for ISO accreditation as a test laboratory, conduct proficiency testing and report the results of all such testing. Accredited approved test laboratories must maintain records of all certification tests, proficiency tests and compliance audit test data. Approved test laboratories must be approved for wood heater certification under subpart AAA or must be an independent third-party test laboratory that is accredited by a nationally recognized accrediting entity to perform testing using the test methods specified in subpart AAA. The final rule allows a three-year extension of current EPA accreditations of labs (as approved test laboratories). We assume that 6 laboratories will submit applications to become approved test labs between 2015 and 2017. Current EPA-accredited laboratories may retain their accreditation and may conduct testing as approved test labs until 3 years after the effective date of this rule. Two of the labs are assumed to already be ISO-accredited and will need to apply to be approved test laboratories for subpart AAA testing and four labs are assumed to need to obtain ISO-accreditation and apply to be approved test labs for subpart AAA testing.
      This ICR assumes that there is an overlap of laboratories that will obtain accreditation and approval as approved testing laboratories and as third-party certifiers under subpart AAA. The only final amended subpart AAA testing laboratory and third-party certifier recordkeeping and reporting burden costs not passed on to the manufacturer would be the burden associated with obtaining ISO accreditation, proficiency testing and reporting required for approved test laboratories to maintain accreditation and approval as test labs, and specified recordkeeping requirements (e.g., certification tests, proficiency tests, QA program inspections, audit test results). 
      There are an estimated 66 existing manufacturers that will be subject to the New Residential Wood Heater NSPS. We recognize that this value may be high. We obtained information on the number of existing manufacturers by appliance type, which may double count manufacturers that make more than one type of appliance. Also, there seems to be a certain amount of consolidation in the industry. However, the number of new manufacturers, particularly outside of the United States is unknown. Therefore, we consider the total of 66 manufacturers to be a reasonable estimate of the number of new and existing manufacturers. 
      Manufacturers of new residential wood heating devices are required to submit applications for certification of model lines, to submit results of emissions tests conducted to demonstrate that the model lines would comply with the emission limits and produce certified units according to a QA plan approved by an independent third-party certifier. The final rule allows heaters/stove models that meet specified EPA criteria that show compliance with the Step 1 emission standards to be automatically deemed as certified to meet the Step 1 emission standards under this final rule until the Step 2 emission standards compliance date. Manufacturers must submit a notification of the initial test and biennial reports that each certified model line remains unchanged. They must also maintain records of all certification data, maintain results of QA program inspections and emissions test data, and seal and store the tested appliance. 
      Manufacturers are also required to apply permanent labels on each applicable unit prior to sale. These labels provide important compliance information to enforcement officials and important information to consumers for purchasing appliances. The amended rule also specifies that manufacturers have the option of using temporary labels for the cleanest heaters in order to provide consumers the ability to select wood heaters that meet or exceed the Step 2 emission standards prior to the Step 2 emissions standards 2020 compliance date. Temporary labels may also be used to indicate wood heaters that meet Step 2 emission standards based on cord wood instead of crib wood, allowing consumers to select heaters better tuned to in-home performance.
      For the final amended New Residential Wood Heater NSPS, the components of the total annual responses attributable to this ICR are test notifications, applications for certification, biennial reporting for certified models, applications for accreditation, test report submittals, QA audit reports and test lab proficiency reporting for the 72 respondents (66 manufacturers and 6 testing laboratories (including both approved test laboratories and third-party certifiers)) that will be subject to the rule. The number of total annual responses for subpart AAA is estimated at 246.
(e)	Bottom Line Burden Hours and Cost Tables.
      (i) Respondent Tally. The bottom line respondent burden hours and costs for the 3 years (2015-2017) covered by this ICR are presented in Table 1 (located at the end of this supporting statement). The average annual burden for the recordkeeping and reporting requirements in subpart AAA for the estimated 72 respondents (66 manufacturers and 6 laboratories (including approved test labs and third-party certifiers)) that will be subject to the New Residential Wood Heater NSPS is estimated to be 2,947 person-hours, with an estimated average annual labor cost of $250,551 (approximately $179,000 for manufacturers, $16,000 for third-party certifiers and $55,000 for test laboratories) and estimated annual capital/start-up costs of $1,466,438.
	(ii) The Agency Tally. The average annual federal government cost is approximately $32,603 for approximately 716 hours for subpart AAA. The bottom line agency burden hours and costs for the 3 years covered by this ICR are presented in Table 2 (located at the end of this supporting statement). 
	(iii) Variations in the Annual Bottom Line. This section does not apply since no significant variation is anticipated.

(f)	Reasons for Change in Burden.
	This ICR requests a reduction in 8,802 total annual labor hours (11,749 - 2,947) and an associated decrease in total annual respondent burden cost for reporting and recordkeeping of $898,661 ($1,149,212 - $250,551). This ICR requests a decrease in the total annual capital and operation and maintenance costs of $269,637 ($1,736,075- $1,466,438). The predominant reason for the changes in costs/burden is the result of revisions to the NSPS (program changes). The amendments to subpart AAA will have several major impacts. 
      The first of these is the change in the number of affected appliances because of the inclusion of single burn rate stoves and all wood-burning pellet stoves. Although this change increases the number of certification applications and certification tests to be processed over the clearance period for those models that do not qualify for automatic certification with the Step 1 emission standards, it is important to note that by the final rule allowing for automatic certification with the Step 1 emission standards for those models that hold certificates that meet the EPA's criteria as meeting the Step 1 emission standards, the number of certification tests/applications in the initial three-year ICR period focuses on only those wood stove models that have not yet demonstrated that they can meet the Step 1 emission standards.
      The second impact results from changes in calculating estimates for permanent labels for new models. Previously, we estimated costs for permanent labels based on the number of units shipped. Our new estimates calculate costs based on the number of model lines consistent with cost estimates provided in an analysis prepared for the Hearth, Patio & Barbecue Association (HPBA) by Ferguson, Andors & Company.
	The third impact results from changes to the QA requirements and use of a third-party certifier certification process. The focus in the three-year clearance period will be for manufacturers to design and certify stoves to meet the new emission limits (where necessary) as demonstrated through certification testing and to begin to implement the new QA-related provisions. The new QA and third-party certifier certification process provisions of the revised subpart AAA are implemented in order to ensure initial and continuing compliance with the applicable emission limits. In the long run, the combination of the use of ISO third-party certifier and test laboratories should streamline the certification and accreditation process for the industry and laboratories and decrease the amount of time spent by the EPA in reviewing QA-related documents. These changes, combined with increasing automation and experience in complying with this standard result in less capital and operation and maintenance costs as well as recordkeeping and reporting burden.
	The fourth impact results from changes to streamline reporting and recordkeeping requirements to those that are essential for implementation and enforcement of the rule and that reflect the agency's experience under the current subpart. For example, we no longer use the number of units sold as the trigger for model line QA audits, so it is no longer important for retailers to track the number of units sold. These changes reduce industry burden, while simultaneously not affecting the agency's ability to enforce the standard. We have also carefully reviewed the requirements included in this supporting statement to focus on activities that routinely occur. For example, revocation of certification and/or laboratory accreditation is extremely rare and is not reflected in this estimate of reporting and recordkeeping. Instead, we have focused on the routine activities that serve to demonstrate that sources are in compliance with the rule.
	The fifth impact results from changes in labor rates used. The labor rates used are greater for managerial and slightly less for technical and clerical than those used in the currently approved ICR based on May 2013 labor rates obtained from the Bureau of Labor Statistics for the Ventilation, Heating, Air-Conditioning and Commercial Refrigeration Equipment Manufacturing (NAICS 333400).
(g)	Burden Statement
	The average annual respondent burden for the final Residential Wood Heating NSPS is approximately 41 hours with an approximate average annual burden per response of 12 hours.
      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 currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR part 60 are listed in 40 CFR part 9.
	To comment on the agency's need for this information, the accuracy of the provided burden estimates and any suggestions for minimizing respondent burden, including through the use of automated collection techniques, the EPA has established a public docket for this ICR under Docket ID No. EPA-HQ-OAR-2009-0734, which is available for online viewing at http://www.regulations.gov, or in person viewing at the Air and Radiation Docket and Information Center in the EPA Docket Center (EPA/DC), EPA WJC West Building, Room 3334, 1301 Constitution Ave., NW, Washington, DC.
