ACTION: Final rule. AGENCY: The Environmental Protection Agency (EPA) is taking final action to revise the Standards of Performance for New Residential Wood Heaters and to add a new subpart: Standards of Performance for New Residential Hydronic Heaters and Forced-Air Furnaces. Today’s rule is authorized by section 111(b) and section 114 of the Clean Air Act (CAA). The EPA is not finalizing, at this time, the proposed Standards of Performance for New Residential Masonry Heaters in order to allow additional time for the Masonry Heater Association to finish their efforts to develop revised test methods, an emissions calculation program and an alternative dimensioning standard. This final rule achieves several objectives for new residential wood heaters, including applying updated emission limits that reflect the current best systems of emission reduction; eliminating exemptions over a broad suite of residential wood combustion devices; strengthening test methods as appropriate; and streamlining the certification process. Residential wood smoke emissions are a significant national air pollution problem and human health issue. These emissions occur in many neighborhoods across the country, including minority and lowincome neighborhoods, and impact people in their homes. To the extent that children and other sensitive populations are particularly susceptible to asthma, and that minority populations and low-income populations are more vulnerable, this rule will significantly reduce the pollutants that adversely affect their health. On an economic basis, the public benefits of this rule vastly outweigh the costs, with every dollar in additional cost producing more than $100 in public benefit. This final action does not include any requirements for heaters solely fired by gas, oil or coal. In addition, it does not include any new requirements associated with appliances mstockstill on DSK4VPTVN1PROD with RULES2 SUMMARY: VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 that are already in use. The EPA continues to strongly encourage state, local, tribal, industry and consumer efforts to change out (replace) older heaters with newer, cleaner, more efficient heaters. Additional information is on the EPA Burn Wise Web site at www.epa.gov/burnwise. Also, we encourage state, local, and tribal authorities to develop site-specific installation and operating requirements to help ensure healthy air for all.

Executive Summary The purpose of this action is to finalize amendments to the Standards of Performance for New Residential Wood Heaters (40 CFR part 60, subpart AAA) and to add one new subpart: Standards of Performance for New Residential Hydronic Heatersand Forced-Air Furnaces (40 CFR part 60, subpart QQQQ). This final action was developed following a CAA section 111(b)(1)(B) review of the 1988 promulgated subpart AAA (53 FR 5860, February 26, 1988), i.e., the 1988 New Source Performance Standards (NSPS). Section 111 requires the EPA to establish standards based on best systems of emission reduction (BSER). Section 111(b) requires emission standards for affected sources and section 111(h)(2)(B) allows the EPA to establish work practices and operational standards or combinations of standards in certain cases, such as when testing is impractical due to technological or economic limitations. The current body of evidence strongly supports revision of the 1988 NSPS to capture the technology improvements and enhanced performance of such units since 1988 and to expand the applicability of these standards to include additional wood-burning residential heating devices that are available today. Section 111 requires the EPA to consider costs and economic impacts. The potential impact on this industry that is comprised of over 90 percent small businesses was a concern to the EPA, and we have minimized these potential impacts to the degree possible while still achieving significant emission reductions. For example, we have incorporated stepped (phased) emission limits and streamlined certification procedures to ease the transition. The health benefits associated with these regulations are substantially greater than the cost to manufacture cleaner, lower-emitting appliances. In fact, the public health PO 00000 Frm 00003 Fmt 4701 Sfmt 4700 13673 benefits of this rule outweigh the costs by more than 100 times. As discussed in the preamble to the February 3, 2014, proposed rule, particulate pollution from wood heaters is a significant national air pollution problem and human health issue. Residential wood smoke contains fine particles with an aerodynamic diameter of 2.5 micrometers or less (PM2.5), carbon monoxide (CO), volatile organic compounds (VOC), toxic air pollutants (e.g., benzene and formaldehyde), and climate-forcing emissions (e.g., methane and black carbon). Residential wood smoke can contribute to unhealthy levels of PM2.5 in many neighborhoods nationwide, including in minority and low-income neighborhoods, and impact people in their homes. To the extent that children and other sensitive populations are particularly susceptible to asthma, and that minority populations and low-income populations are more vulnerable to the effects of air pollution, this rule will significantly reduce the pollutants that adversely affect their health. Populations that are at greater risk for experiencing health effects related to fine particle exposures include older adults, children and individuals with pre-existing heart or lung disease. Each year, smoke from wood heaters produces hundreds of thousands of tons of fine particles throughout the country—mostly during the winter months. Nationally, residential wood combustion accounts for 44 percent of total stationary and mobile polycyclic organic matter (POM) emissions, which account for nearly 25 percent of all area source air toxics cancer risks and 15 percent of noncancer respiratory effects.1 Residential wood smoke causes many counties in the U.S. to either exceed the EPA’s health-based national ambient air quality standards (NAAQS) for fine particles or places them on the cusp of exceeding those standards.2 To the degree that older, higher emitting, less efficient wood heaters are replaced by newer heaters that meet the requirements of this rule, these requirements for cleaner new stoves will result in substantial reductions in emissions, and thus in exposure, producing reduced health impacts. A summary of the estimated health 1 Strategies for Reducing Residential Wood Smoke. EPA–456/B–13–001, March 2013.

E:\FR\FM\16MRR2.SGM 16MRR2 13674 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations benefits is shown in Table 1 below. More details are in the final Regulatory Impact Analysis (RIA) in the docket for this rule. Consistent with Executive Order 13563, ‘‘Improving Regulation and Regulatory Review,’’ we have estimated the cost and benefits of the final rule. The estimated annual net benefits at a 3-percent discount rate are $3.4 billion to $7.6 billion, and $3.1 billion to $6.9 billion at a 7-percent discount rate in 2013 dollars. The net benefits estimate reflects 8,269 tons of PM2.5 emission reductions per year, and a total annualized cost of $45.7 million, producing an unusually large net benefit for this rule of more than 100 times the costs, and even greater net benefits coming from the new rule applied to single burn rate stoves. We estimate that this rule will result in 360 (Krewski, et. al., 2009) or 810 (Lepeule, et. al., 2012) avoided premature deaths per year. The non-monetized benefits include 46,000 tons of CO reductions per year; 9,300 tons of VOC reductions per year; reduced exposure to hazardous air pollutants (HAP), including formaldehyde, benzene, and polycyclic organic matter (POM); reduced climate effects due to reduced black carbon emissions and reduced greenhouse gases emissions; reduced ecosystem effects; and reduced visibility impairments. Table 1 is a summary of the results of the analysis per type of residential wood heater. We have provided estimates reflecting average annual impacts for the 2015 to 2020 timeframe, which are the implementation years analyzed in the RIA for this final rule.

These results include units anticipated to come online and the lowest cost disposal assumption. Total annualized costs shown in this table are estimated at a 7-percent interest rate to be consistent with guidance from the Office of Management and Budget (OMB). Total annualized costs are also estimated at a 3 percent interest rate for each source category to be consistent with OMB guidance, and these costs are about 13 percent less than the total annualized costs presented in this table. These costs are presented in the RIA and in the cost memoranda for this final rule. The monetized net benefits with total annualized costs at a 3 percent interest rate are minimally different than those calculated with total annualized costs at a 7 percent interest rate. b Total monetized benefits are estimated at a 3-percent discount rate. The total monetized benefits reflect the human health benefits associated with reducing exposure to PM2.5 through reductions of directly emitted PM2.5. It is important to note that the monetized benefits include many but not all health effects associated with PM2.5 exposure. Benefits are shown as a range from Krewski et al. (2009) to Lepeule et al. (2012). These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effect estimates by particle type. Because these estimates were generated using benefit-per-ton estimates, we do not break down the total monetized benefits into specific components. B. Does this action apply to me?

Background Information for This Final Rule A. What is the NSPS program? Under section 111 of the CAA, ‘‘Standards of Performance for New Stationary Sources,’’ the EPA lists categories of sources that, in the EPA’s judgment, cause or contribute significantly to air pollution, which may reasonably be anticipated to endanger public health or welfare pursuant to section 111(b)(1)(A). Section 111(b)(1)(B) requires the EPA to promulgate federal standards of performance for new sources within those categories. At the time the EPA establishes standards for a source category, the EPA prepares an analysis of the potential costs and benefits associated with the NSPS, which also includes the benefits from reductions in pollutants for which the standards do not set limits. For example, emission reductions associated with the requirements of this final rule will generate health benefits by reducing emissions of PM2.5, other criteria pollutants, such as CO, and non-criteria HAP. In addition, section 111(h) authorizes the EPA to promulgate design, equipment, work practice, operational, or combinations of standards to reflect the best systems of continuous emission reduction. The NSPS established under section 111(b)(1)(B) do not establish standards of performance for existing sources. However, numerous states have acted VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 independently of this rule to address new and existing sources as part of state implementation plan (SIP) measures necessary to ensure attainment and maintenance of the NAAQS. The level of control prescribed by section 111 of the CAA is BSER. In analyzing BSER, the EPA uses available information and considers the emissions reductions and incremental costs for different systems available at reasonable cost. The residential wood heaters source category is different from most NSPS source categories in that it is for mass-produced residential consumer products. Thus, important elements in determining BSER include the significant costs and environmental impacts of delaying production while models with those systems are designed, tested, field evaluated and certified. Section 111(b)(1)(B) of the CAA requires that the standards be effective upon the effective date of the NSPS. As noted earlier and discussed more fully later in this preamble, the stepped (phased) approach for residential wood stoves/ heaters, hydronic heaters and forced-air furnaces that the EPA is promulgating considers these factors. That is, for this rulemaking, the EPA has determined the appropriate emission limits and compliance deadlines that together are representative of BSER. Section 111(b)(1)(B) of the CAA requires the EPA to periodically (every 8 years) review an NSPS unless it determines ‘‘that such review is not appropriate in light of readily available information on the efficacy of such standard.’’ In making revisions to an NSPS, the EPA will revise the standards of performance to reflect improvements in methods for reducing emissions, including consideration of what emissions limitation is achieved in practice. Numerous stakeholders have stated that the current body of evidence strongly justifies the revision of the current residential wood heaters NSPS to capture the improvements in performance of such units since 1988 and to expand the applicability of this NSPS to include additional residential wood-burning heating devices that are available today. Some stakeholders have suggested that the EPA also develop additional NSPS to regulate residential heating devices that burn fuels other than or in addition to wood, e.g., coal, corn or grass. This final rule does not include any new federal requirements for heaters that solely burn fuels other than wood. However, the EPA may consider the need for such requirements during the next review. PO 00000 Frm 00005 Fmt 4701 Sfmt 4700 13675 B. Why is residential wood smoke a concern? There is widespread recognition of the health impacts of particle pollution, to which wood smoke is a contributing factor in many areas. Wood smoke contains a mixture of fine particles and toxic air pollutants (e.g., benzene and formaldehyde) that can cause burning eyes, runny nose, and bronchitis. Exposure to fine particles has been associated with a range of health effects, including aggravation of heart or respiratory problems, changes in lung function and increased respiratory symptoms, as well as premature death. Populations that are at greater risk for experiencing health effects related to fine particle exposures include older adults, children and individuals with pre-existing heart or lung disease. Each year smoke from wood heaters contributes hundreds of thousands of tons of fine particles throughout the country—mostly during the winter months. Nationally, residential wood combustion accounts for 44 percent of total stationary and mobile polycyclic organic matter (POM) emissions, which accounts for nearly 25 percent of all area source air toxics cancer risks and 15 percent of noncancer respiratory effects.3 Residential wood smoke causes many counties in the U.S. to either exceed the EPA’s health-based NAAQS for fine particles or places them on the cusp of exceeding those standards. For example, in places such as Keene, New Hampshire; Sacramento, California; Tacoma, Washington; and Fairbanks, Alaska; wood combustion can contribute over 50 percent of daily wintertime fine particle emissions.4 The concerns are heightened because wood stoves, hydronic heaters, and other heaters are often used around the clock in many residential areas. To the degree that older, dirtier, less efficient wood heaters are replaced by newer heaters that meet or exceed the requirements of this rule, the emissions would be reduced, and thus exposure as well, and fewer health impacts should occur. The health and air quality concerns associated with particle pollution and the effects of wood smoke are discussed in detail in the original listing of residential wood heaters under section 111(b) in the February 18, 1987, Federal 3 Strategies for Reducing Residential Wood Smoke.

As discussed in the preamble to the February 3, 2014, proposed rule, and, in the Executive Summary (section I.A) of this preamble, particulate pollution from wood heaters is a significant national air pollution problem and human health issue. To the degree that older, higher emitting, less efficient wood heaters are replaced by newer heaters that meet the requirements of this rule, setting these requirements for cleaner new stoves will result in substantial reductions in exposure and reduced health impacts. mstockstill on DSK4VPTVN1PROD with RULES2 III. Summary of the Final Rule A. General In response to the results of the review of the 1988 NSPS and in response to comments on the proposed rule and the NODA, the EPA is amending 40 CFR part 60, subpart AAA, Standards of Performance for New Residential Wood Heaters, and adding a new subpart QQQQ, Standards of Performance for New Hydronic Heaters and Forced-Air Furnaces. Subpart AAA applies to room heaters. This final rule broadens the applicability of wood heaters subject to the 1988 NSPS beyond adjustable burn rate wood heaters (the focus of the 1988 regulation) to specifically include all single burn rate wood heaters/stoves/ appliances and pellet heaters/stoves/ appliances and all other residential wood heaters except those specifically exempt in the rule, e.g., hydronic heaters and forced air furnaces regulated by subpart QQQQ. (Some pellet heaters/ stoves/appliances were not affected by the 1988 regulation.) This preamble uses the following terms interchangeably for appliances subject to subpart AAA: wood heaters, stoves and heaters/stoves/ appliances. Subpart QQQQ applies to two specific types of wood heaters: hydronic heaters and forced-air furnaces plus any other wood-burning affected appliance that meets the definition of central heater. This preamble uses the terms forced-air furnaces and warm-air furnaces interchangeably for such heaters/furnaces/appliances affected by subpart QQQQ. Wood heaters, hydronic heaters and forced-air furnaces manufactured after the effective date of this final rule will be required to meet PM emission limits. VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 This final rule does not include any federal emission limitations that would apply to heaters fueled solely by gas, oil or coal. In addition, this final rule does not include any new federal requirements associated with wood heaters or other wood-burning appliances that are already in use in people’s homes. The EPA continues to encourage state, local, tribal, manufacturer, retailer and consumer efforts to change out (replace) older heaters with newer, cleaner, more efficient heaters. Also, we continue to encourage state, local, and tribal authorities to develop site-specific installation and operating requirements and oversight to help ensure healthy air for all. For this final action, the effective date is May 15, 2015 to allow for Congressional Review under the Congressional Review Act (CRA). Under the CRA, 5 U.S.C. 801(a)(3), the effective dates of all ‘‘major’’ rules are delayed for 60 calendar days after they are submitted to Congress or after they are published in the Federal Register, whichever date is later. This final action is a ‘‘major’’ rule within the meaning of the CRA. Section IV summarizes the changes to the proposed rule reflected in the final rule, and section V provides a summary of the major comments received and our responses. 1. Certification Testing and Compliance As with the 1988 NSPS, because of concern regarding potential negative impacts on small businesses and potential certification delays, this revised subpart AAA for wood heaters/ stoves and new subpart QQQQ for hydronic heaters and forced-air furnaces require manufacturers to participate in a certification program that tests a representative heater per model line rather than testing every heater. If the representative heater meets the applicable emission limits contained in this rule, the entire model line may be certified. Individual heaters within the model line are still subject to all other requirements, including labeling and operational requirements. Manufacturers are required to have quality assurance programs to ensure that all heaters within the model line conform to the certified design and meet the applicable emission limits. The EPA will continue to have the authority to conduct audits to ensure compliance. Additional requirements apply to entities other than the manufacturer. Wholesalers and retailers are also subject to the limits on sales of noncertified affected heaters. Wood heater test laboratories and certifying entities PO 00000 Frm 00006 Fmt 4701 Sfmt 4700 are subject to quality assurance and reporting requirements. This final rule for subpart AAA and subpart QQQQ requires the proper burn practices that have applied to the owner or operator of a wood heating appliance regulated under subpart AAA since 1988. In addition, new pellet heater/stove owners and operators will be required to use only the grades of pellet fuels and wood chips that are included in the owner’s manual based on the heater/ stove certification tests. In this final rule, we are revising the original 1988 enforcement and audit provisions to reflect changes in industry practices and development of new tools and procedures. We are also taking final action to improve the previous test methods as well as adding new test methods. More details are in sections IV.D and V. 2. Stepped Compliance Approach The 1988 NSPS addressed some of the specific characteristics of this source category by developing a stepped compliance approach that provided manufacturers a two-phased implementation of emission limits. Considering that over 90 percent of the manufacturers and retailers are small businesses, we have included this approach in the revised subpart AAA and new subpart QQQQ in order to allow manufacturers lead time to develop, test, field evaluate and certify current technologies across their consumer product lines to meet Step 2 emission limits and in most cases to allow retailers to sell-through inventory. Upon the effective date of this final rule, all new residential wood heaters subject to subparts AAA and QQQQ will be required to meet the NSPS standards. The standards are phased from immediate requirements on the effective date to Step 2 emission limits five years later. The specific emission limits and dates for subparts AAA and QQQQ are shown in Table 3 and Table 4, respectively. To further ease the transition on small businesses, the EPA will not require new testing of heaters that have current certificates of compliance under the 1988 NSPS that show they meet the Step 1 emission levels. Those certificates are automatically extended beyond their current expiration date until the compliance deadline for the Step 2 emission limits. Also, this final rule automatically deems certified hydronic heaters that have been qualified at the Step 1 emission level (or better) under the EPA voluntary partnership program for hydronic heaters or forced-air furnaces that have been independently certified at the Step 1 emission level (or E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations mstockstill on DSK4VPTVN1PROD with RULES2 better) or under Canadian Standards Association B415.1–10. 3. NSPS Labels The final rule requires that each room heater under subpart AAA and central heater under subpart QQQQ be equipped with a permanent label meeting the applicable requirements in § 60.536 and § 60.5478, respectively. The permanent label must include identifying information for the unit and its compliance certification status. The permanent label must be installed so that it is readily visible both before and after the unit is installed. This requirement is needed to assist state, local and tribal officials in determining if a unit complies with state, local and tribal rules and in determining eligibility for any future change out (replacement) programs. Note that ‘‘readily visible’’ does not mean under the body of freestanding stove but it does allow an easily removable decorative facade to cover the label. ¸ In the 1988 NSPS, temporary labels (e.g., hangtags) were required for wood heaters that are subject to the standards, as well as ones that are not (e.g., coal heaters/stoves). These temporary labels were intended to assist consumers in comparing different appliance models and to inform the consumer about the importance of proper operation and maintenance. We proposed to remove the requirement for temporary labels, and we requested comment. After reviewing the comments received, the EPA now concludes that these temporary labels are most valuable if they assist purchasers in identifying the cleanest and most efficient heaters. Therefore, in this final rule the EPA is allowing (voluntary) a temporary NSPS label (hangtag) for each adjustable burn rate heater, single-burn rate heater, pellet heater/stove, hydronic heater and forced-air furnace sold at retail that meets the Step 2 emission limits before the Step 2 compliance date. This temporary label option will end upon the Step 2 compliance date. In addition, we are providing an alternative compliance option for manufacturers who choose to demonstrate compliance with Step 2 emission limits using cord wood testing rather than the standardized crib wood testing, currently used for the primary compliance option for appliances regulated under subpart AAA and for hydronic heaters under subpart QQQQ. As discussed in the preamble to the February 3, 2014, proposed rule, crib wood is a specified configuration and quality of dimensional lumber and spacers that improves the repeatability of the test method. Cord wood is a VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 different specified configuration and quality of wood that more closely resembles what a typical homeowner would use. Cord wood testing is a better measure of how the heaters will perform on the type of fuel commonly used in homes. Each of these models would be equipped with both a permanent label and the voluntary option of a special temporary label (hangtag) informing consumers that these wood heaters were tested and certified when burning cord wood. The specific emission limits are discussed in sections III.B and III.C. 4. New Residential Masonry Heaters (Proposed Subpart RRRR) The EPA is not taking final action at this time on proposed subpart RRRR for new residential masonry heaters. Our reason for taking no action at this time is to allow additional time for the Masonry Heater Association (MHA) to finish their efforts to develop revised test methods, an emissions calculation program and an alternative dimensioning standard. The MHA believes these efforts are critical because most masonry heaters are custom built on-site and testing each custom model would be difficult. The nationwide emission impacts of delaying regulating subpart RRRR are small relative to the impacts of regulating subparts AAA and QQQQ. Fewer than approximately 1,000 masonry heaters are manufactured each year and a total of less than 10 tons per year of PM2.5 are currently emitted. In comparison, new wood burning appliances covered by subparts AAA and QQQQ are estimated to number more than 200,000 (2015) and currently emit more than 11,000 tons per year of PM2.5.5 B. Room Heaters (Revised Subpart AAA) 1. Applicability After the effective date, new heaters will be required to meet the updated standards. The new standards apply not only to adjustable burn rate wood heaters (the focus of the original regulation), but also to single burn rate wood heaters/stoves, pellet heaters/ stoves, and any other affected appliance as defined in revised subpart AAA as a ‘‘room heater.’’ Subpart AAA, as amended, does not apply to new residential hydronic heaters or new residential forced-air furnaces because they are subject to their own subpart. The revised subpart AAA does not apply to fireplaces as defined in Subpart AAA. This final rule tightens the definition for ‘‘cook stoves’’ and adds 5 Memo to USEPA from EC/R, Inc. Estimated Emissions from Wood Heaters. January 2015. PO 00000 Frm 00007 Fmt 4701 Sfmt 4700 13677 definitions for ‘‘camp stoves’’ and ‘‘traditional Native American bake ovens’’ to clarify that they are not subject to the standard other than appropriate labeling for cook stoves and camp stoves and no requirements for traditional Native American bake ovens. Finally, the revised subpart AAA clarifies that the emission limits apply only to wood-burning devices (i.e., not to devices that only burn fuels other than wood, e.g., gas, oil or coal). 2. Automatic EPA Certification for Currently Certified Heaters/Stoves That Meet the Step 1 Emission Levels In this final rule we make clear that those heaters/stoves with EPA certifications under the 1988 NSPS that show compliance with the Step 1 emission levels will be automatically deemed as certified to meet the Step 1 emission limits under this final rule until the Step 2 compliance date. No separate certification will be required. Over 85 percent of heaters/stoves being sold today already meet the Step 1 emission limit. This automatic certification will avoid unnecessary economic impacts on those manufacturers (over 90 percent are small businesses) who can then focus their efforts on developing a full range of cleaner models that meet Step 2 emission levels. This measure should also help avoid potential delays at laboratories conducting certification testing for heaters newly subject to the NSPS. 3. Two-Step Compliance Approach We are promulgating a two-step compliance approach that will apply to all new adjustable burn rate wood heaters, single burn rate wood heaters and pellet heaters/stoves. Under this approach, Step 1 emission limits for these sources will apply to each source manufactured on or after the effective date of the final rule or sold at retail on or after December 31, 2015. The approximately 8-month additional time for the retail sale requirement will allow retailers to sell their inventories of heaters that do not comply with the Step 1 emission limits. Step 2 emission limits for these sources will apply to each heater manufactured or sold at retail on or after the date 5 years after the effective date of the final rule. We are not including the alternative threestep emission limit compliance approach for which we also requested comment in the proposal. The comments overwhelmingly indicated that the three-step emission limit approach was inferior not only environmentally but also economically because it would, in effect, require E:\FR\FM\16MRR2.SGM 16MRR2 13678 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations many small manufacturers to engage in two rounds of research and development (R&D) rather than one in order to obtain the same eventual endpoint. Table 3 summarizes the PM emissions limits that apply to each wood heater under this two-step approach. Note that the emissions standards are ‘‘as measured’’ by the test methods specified in the rule and are labeled as PM although the PM is essentially all PM2.5. This avoids the potential extra testing costs of measuring PM2.5 specifically.

Step 2: 5 years after the ef2.0 g/hr. fective date of the final rule. Step 2: Cord wood alter2.5 g/hr. native compliance option. We are allowing an alternative compliance option for manufacturers who choose to certify using cord wood (rather than crib wood) to meet the Step 2 limits. (As discussed earlier in this preamble, crib wood is a specified configuration and quality of dimensional lumber and spacers that improves the repeatability of the test method. Cord wood is a different specified configuration and quality of wood that more closely resembles what a typical homeowner would use.) Special permanent and temporary labels for room heaters certified with cord wood would specify that they meet a PM emissions limit of 2.5 g/hr. The bases for the crib wood primary emission limit of 2.0 g/hr and the cord wood alternative compliance option emission level of 2.5 g/hr for wood stoves, as well as the limited environmental impact of the differences in these levels, are discussed in section V.A BSER and Particulate Emission Limits for Room Heaters (revised subpart AAA). The proposal would have required cord wood testing for all Step 2 compliance certifications. Cord wood testing is a better measure of how stoves actually perform in home use; however, we are concerned that many manufacturers (over 90 percent are small businesses) do not yet have experience with designing their stoves to perform well with cord wood testing. Some manufacturers may not be ready for cord wood testing by the Step 2 compliance date and that would result in unreasonable economic impacts. Allowing the cord wood alternative VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 compliance option acknowledges the efforts of the industry leaders and encourages others to follow their example. The revised subpart AAA does not include a compliance extension for small volume manufacturers. An extension for manufacture of adjustable burn rate heaters is not necessary because over 85 percent of these appliances already comply with Step 1 emission levels. We are making a single determination of BSER for catalytic, noncatalytic and hybrid heater systems so as not to restrict open market competition. As in the 1988 NSPS, we are requiring manufacturers to provide warranties on the catalysts, prohibit the operation of catalytic heaters/stoves without a catalyst and require operation according to the owner’s manual. In addition, we are requiring manufacturers to provide warranties for noncatalytic and hybrid heaters/stoves and require operation according to the owner’s manual. As discussed at proposal, we considered requiring efficiency standards (heat output divided by fuel input) to ensure that stoves are efficient and burn no more wood than necessary for the heat demand so that the consumers can save money on fuel and so that the emissions are lower. We did not propose an efficiency standard because we did not have sufficient data, but the final rule uses our authority under section 114 to require the manufacturer to submit third-party efficiency test data, submit the test data report to the EPA and post the results on the manufacturer’s Web site. Also, we will include this submitted information on the EPA Web site. This will help consumers to make informed choices to reduce fuel costs and emissions now and provide data for us to consider for future rulemaking. 4. Emission Testing, Reporting and Certification We are requiring emission testing, reporting and certification based on crib wood to demonstrate compliance with Step 1 and Step 2 emissions limits. As discussed in the preamble to the February 3, 2014, proposed rule, ‘‘crib wood’’ is a specified configuration and quality of dimensional lumber and spacers that improves the repeatability of the test method. In this final rule, we are also establishing an alternative compliance option that allows manufacturers to use cord wood for the certification tests. ‘‘Cord wood’’ is a different specified configuration and quality of wood that more closely resembles what a typical homeowner would use. PO 00000 Frm 00008 Fmt 4701 Sfmt 4700 Commenters overwhelmingly agreed that tuning heaters for crib wood certification tests often results in poorer performance in homes. Based on the existence of a viable draft cord wood test method and the expectation at proposal that the ASTM International (formerly known as American Society of Testing and Materials) test methods for cord wood would be complete soon after the NSPS proposal and that significant testing of wood heaters retuned to perform well on cord wood would occur before promulgation of this final rule, the EPA proposed to require testing only with cord wood for compliance with Step 2 emissions limits. We still encourage manufacturers to design wood heaters that best represent in-home performance on cord wood that consumers use as soon as possible. However, the ASTM cord wood test methods have not been completed and only limited testing using the draft methods has occurred. We received numerous comments from noncatalytic stove manufacturers and laboratories and some states with concerns about when the cord wood test methods would be ready and how quickly noncatalytic stoves could be redesigned to perform well with cord wood certification testing that we proposed for Step 2, i.e., 5 years after the effective date. As discussed in the NODA, as of May 2014, we had test data for three catalytic or hybrid wood heaters/stoves that performed very well on cord wood. However, considering all of the above, we have determined that we do not have sufficient data at this time to support a regulatory requirement for cord wood testing. We expect that many manufacturers will choose the alternative cord wood compliance testing option so that consumers will have more opportunities to purchase stoves that are tuned for inhome use. We will consider alternative cord wood test method requests on a case-by-case basis until we are convinced that improved test methods have been sufficiently demonstrated that they can be relied upon for regulatory purposes. For now, we will be receptive to alternative test method requests that use the current ASTM draft method. Also, we will be receptive to other requests that are sufficiently demonstrated, ideally using the EPA Method 301 validation procedures. Additionally, we expect that within the next few years we will receive enough cord wood test data for the EPA to establish revised certification requirements based on cord wood testing. The final rule requires that pellets for the certification tests be only those that E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations have been graded under a licensing agreement with a third-party organization and meet the minimum quality specifications in § 60.532. Commenters indicated that several organizations are currently available and others are planned, for example, the Pellet Fuels Institute (PFI), ENplus and CANplus. Details of the PFI program are available at https://pelletheat.org/pfistandards/pfi-standards-program/. Details of the ENplus program are at https://www.enplus-pellets.eu/wpcontent/uploads/2012/01/ENplusHandbook-2.0.pdf. Details of the CANplus program are at https://control union.ca/fileupload/CA/Certifications/ ENplusCANplus/CANplus_handbook_ v2-0.pdf. Manufacturers’ data show that pellet fuel quality assurance is necessary to ensure that the appliances operate properly and meet the certified emission limits. At this time, we lack sufficient data to issue a CO emissions limit in today’s final rule. However, this final rule uses our authority under section 114 to require manufacturers to determine CO emissions during the compliance tests (as is typically done already), report those results to the EPA and include those results on the manufacturer’s Web site, so that data will be available to consumers, and to the EPA and states for CO NAAQS compliance implementation plan considerations and future wood heater rulemakings. We intend to include context and consumer-friendly summaries of the submitted CO emissions data on the EPA Burn Wise Web site also. Like the 1988 subpart AAA, this final rule uses the EPA authority under section 114 of the CAA to require each manufacturer to submit applications for certifications of compliance for all new models. We are revising the certification process to include third-party certifiers in order to reduce the potential for certification delays that could result from insufficient capacity. However, commenters expressed concern, which we share, that there may not be sufficient third-party certifier capacity and review and approval capacity by the EPA, especially in the first year. Therefore, to avoid unfairly restricting the production and sales of manufacturers who do all the things they should do and then potentially have to wait on EPA approval, we have added a conditional, temporary approval by the EPA based on the manufacturer’s submittal of a complete certification application. The application must include the full test report by an EPA-accredited laboratory and all required compliance statements by the manufacturer. The conditional VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 approval would allow manufacture and sales for 1 year or until EPA review of the application, whichever is earlier. Within that year, the manufacturer must submit a certificate of conformity by a third-party certifier. (In this preamble, we use the terms ‘‘third-party certifier,’’ ‘‘certifying body,’’ ‘‘certifying entity’’ and ‘‘certifying body/entity’’ interchangeably.) The EPA is revising the definition of ‘‘Accredited Test Laboratory,’’ from only EPA-accredited laboratories to include laboratories accredited by a nationally recognized accrediting body/entity to perform testing for each of the test methods specified in this NSPS under ISO–IEC 6 Standard 17025. Laboratories must be approved by the EPA before beginning certification testing. Current EPA-accredited laboratories may retain their accreditation until 3 years after the effective date of this final rule. Laboratories that are not currently EPAaccredited must achieve ISOaccreditation and register with the EPA within 6 months of the effective date of this rule. Laboratories must report any changes in their accreditation and any deficiencies found under ISO 17025 to the EPA, and the EPA may revoke approval if warranted. The EPA is requiring a ‘‘CertifyingBody-Based Certification Process’’ beginning 6 months after the effective date of this final rule for all heaters/ stoves except hydronic heaters. For hydronic heaters, the ‘‘Certifying-BodyBased Certification Process’’ is required upon the effective date of this final rule because this certification process has already been required under EPA’s Hydronic Heater Partnership Program since October 2008. Under this process for all heaters/stoves subject to subparts AAA and QQQQ, after testing is complete, a certification of conformity with the PM emissions limits must be issued by a certifying body with whom the manufacturer has entered into contract for certification services. The certifying body must be accredited under ISO–IEC Standard 17065 and register their credentials with the EPA and receive EPA approval prior to conducting any certifications or related work used as a basis for compliance with this rule and report any changes in their accreditation and any deficiencies found under ISO 17065. Any certifying body that is approved by the EPA and is ISO-accredited is required to act in such a way that will not create a conflict of interest and work with integrity and 6 The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) prepare and publish international standards. PO 00000 Frm 00009 Fmt 4701 Sfmt 4700 13679 honesty. The EPA will oversee the certifying body’s work and retain the right to revoke the EPA approvals if appropriate. Upon review of the test report and quality control plan submitted by the manufacturer, the certifying body may certify initial compliance and submit the required documentation on behalf of the manufacturer to the EPA’s Office of Enforcement and Compliance Assurance for review, approval and listing of the certified appliance. The rule continues to require the owner or operator of a wood heating appliance to operate the heater consistent with the owner’s manual and not burn improper fuel. Owners and operators must operate pellet fuel appliances with the grades of pellet fuels that are included in the owner’s manual. Manufacturers are required to void their warranties in cases of improper operation. Numerous states expressed their support for the continuation of these requirements. Some states and local jurisdictions have enforced similar requirements, and this final rule will allow the EPA to approve state requests for delegation of enforcement authority for these NSPS requirements. In addition, we expect many state, local and tribal authorities will adopt some of the important and very successful strategies in Strategies for Reducing Wood Smoke,7 including changing out (replacing) older heaters with newer, cleaner, more efficient heaters and developing site-specific installation and operating requirements to ensure heaters are not over-sized, avoid nuisance conditions, and ensure proper operation, e.g., using EPA Method 22 observations of visible emissions as an indicator of potential poor or improper operation to help ensure healthy air for all. The rule continues to contain the crucial quality assurance provisions in the 1988 NSPS. For example, manufacturers must request EPA approval of model line re-certifications or new certifications whenever any change is made in the original design that could potentially affect the emissions rate for that model line or when any of several specified tolerances of key components are changed. The 1988 requirements for manufacturer quality assurance programs are strengthened in the revised rule by requiring the manufacturer within 6 months after the effective date to 7 Strategies for Reducing Residential Wood Smoke.

The certifying body will conduct regular, unannounced audits to ensure that the manufacturer’s quality control plan is implemented properly. The EPA audit testing programs of the 1988 NSPS are retained under the revised rule, although they are streamlined and simplified to better ensure compliance and to clarify that audits can be based on any information the EPA has available and that audits do not need to be statistically random. Also, the rule clarifies that the EPA and states are allowed to be present during the audits and that states (and other entities, including the public) may provide the EPA with information that may ultimately be used in any EPA enforcement and compliance assurance efforts. mstockstill on DSK4VPTVN1PROD with RULES2 C. Central Heaters: Hydronic Heaters and Forced-Air Furnaces (Subpart QQQQ) 1. Applicability After the effective date, new heaters will be required to meet the new standards. In this final rule, the EPA is adding 40 CFR part 60, subpart QQQQ, which applies to all new wood-fired residential hydronic heaters, wood-fired forced-air furnaces and any other woodfired affected appliance defined in subpart QQQQ as a ‘‘central heater.’’ Wood-fired means designed or marketed to be capable of burning wood or used to burn wood. For example, a coal-fired heater cannot be marketed as capable of wood-burning unless it meet the requirements of this rulemaking and the marketing brochures and owner’s manuals must be clearly specific to coal rather than wood. Hydronic heater means a fuel-burning device designed to burn wood or wood pellet fuel for the purpose of heating building space and/ or water through the distribution, typically through pipes, of a fluid heated in the device, typically water or a water and antifreeze mixture. Forcedair furnace means a fuel burning device designed to burn wood or wood pellet fuel that warms spaces other than the space where the furnace is located, by the distribution of air heated by the furnace through ducts. This new ‘‘central heater’’ categorization better ensures that all appliances affected under this new subpart are included in this final action. Adding subpart QQQQ addresses heater appliance types in the 1987 residential wood heater source category listing that were not regulated by the 1988 NSPS. This new subpart is designed similar to subpart AAA, i.e., certification testing of VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 a representative unit in a model line, label requirements, associated quality assurance requirements and stepped (phased) implementation. The provisions of subpart QQQQ apply to each affected unit that is manufactured or sold at retail on or after May 15, 2015. 2. Automatic EPA Certification for Currently Certified or Qualified Central Heaters That Meet the Step 1 Emission Levels In this final rule we make clear that those hydronic heaters with valid EPA Phase 2 qualifications under the voluntary EPA Hydronic Heater Partnership Agreement of October 12, 2011, or hydronic heaters certified by the New York State Department of Environmental Conservation (NYSDEC) that show compliance with the Step 1 emission limits will be automatically deemed EPA certified to meet the Step 1 emission limits under this final rule until the Step 2 compliance date. Also, residential pellet hydronic heaters/ boilers that have been qualified under the Renewable Heat New York (RHNY) program will be automatically deemed EPA certified to meet Step 1. (Note that the RHNY program requires pellet heating systems to include installation of thermal storage to maintain highefficiency and low emissions performance throughout daily and annual cycles. The minimum size thermal storage for boilers less than 85,000 BTU/hr is 119 gallons or 2.0 gallons per 1,000 BTU/hr, whichever is less. For boilers greater than 85,000 BTU/hr, the minimum heat storage is 2.0 gallons per 1,000 BTU/hr.) No separate EPA certification will be required. Similarly, forced-air furnaces independently certified (i.e., not selftested) under Canadian Standards Association (CSA) B415.1–10 as well as forced-air furnaces certified by the NYSDEC that show compliance with the Step 1 emission limits will be deemed EPA certified to meet the Step 1 emission limits under this final rule until the Step 2 compliance date. This automatic EPA certification will avoid unnecessary economic impacts on those manufacturers (over 90 percent are small businesses) who can then focus their efforts on developing a full range of cleaner models that meet Step 2 emission levels. This measure should also help avoid potential delays at laboratories conducting certification testing for heaters newly subject to the NSPS. PO 00000 Frm 00010 Fmt 4701 Sfmt 4700 3. Stepped Compliance Approach We are promulgating a stepped compliance approach that will apply to all new central heaters. For hydronic heaters, standards will apply to each hydronic heater manufactured after May 15, 2015 and each hydronic heater sold after December 31, 2015. Step 1 p.m. emission limits will apply to each hydronic heaters manufactured on or after May 15, 2015 or sold at retail after December 31, 2015. Step 2 p.m. emission limits will apply to each hydronic heater manufactured or sold at retail on or after May 15, 2020. For hydronic heaters, we are not promulgating the alternative three-step emission limit approach for which we requested comment in the proposal. The comments overwhelmingly indicated that the three-step emission limit approach was inferior not only environmentally but also economically because it would, in effect, require many small manufacturers to engage in two rounds of R&D rather than one in order to obtain the same eventual endpoint. For forced-air furnaces, standards will apply to each forced-air furnace manufactured or sold after May 15, 2015. Work practice and operational standards will apply to each forced-air furnace manufactured or sold at retail after May 15, 2015. Step 1 PM emission limits will apply to small (less than 65,000 BTU/hr heat output) forced-air furnaces manufactured or sold on or after May 16, 2016. Step 1 PM emission limits will apply to large (65,000 BTU/ hr heat output or larger) forced-air furnaces manufactured or sold on or after May 15, 2017. Step 2 PM emission limits will apply to each forced-air furnace manufactured or sold at retail on or after May 15, 2020. For forced-air furnaces, we are not promulgating the alternative three-step emission limit approach for which we requested comment in the proposal. The comments overwhelmingly indicated that the three-step emission limit approach was inferior not only environmentally but also economically because it would, in effect, require many small manufacturers to engage in two rounds of R&D rather than one in order to obtain the same eventual endpoint. However, commenters were very concerned about the infeasibility of enforcing an emission limits for forcedair furnaces due to the technical and economic impracticability of testing and certifying approximately 50 forced-air furnaces in the 60 days between publication of this rule and the effective date. For example, a typical forced-air E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations furnace certification test takes approximately 1 week in the laboratory after the furnace is shipped to the laboratory and a time is scheduled to begin testing. Typically, the laboratory takes approximately 3 or 4 weeks to prepare a complete test report for the manufacturer to submit to the EPA. A reasonable overall estimate is approximately 1.25 months, not counting potential conflicts with other testing in the laboratories. Currently, there are only 4 laboratories that can test forced-air furnaces. We estimate that approximately 12 small forced-air furnaces and 38 large forced-air furnaces would need to be tested as soon as possible. If those tests were to be divided equally among the 4 laboratories, it would take a minimum of approximately 4 months to submit the 12 certification test reports for the small furnaces and an additional year to submit the 38 certification test reports for the large furnaces to the EPA, far longer than the 60 days between the publication date and the effective date. Thus, as noted above, we are requiring work practice and operational standards on the effective date as allowed under section 111(h)(2)(B) of the CAA, and requiring Step 1 PM emission limits for small forced-air furnaces 1 year after the effective date and Step 1 PM emission limits for large forced-air furnaces 2 years after the effective date. Specifically, the manufacturers must develop model-specific descriptions of proper operation and best practices; include them in their owner’s manuals; provide training on them to their distributors; and provide them in written and video format to purchasers/ operators/users of their heaters. The specific details that must be included in owner’s manuals are in § 60.5474 and Appendix I of this rulemaking. The following are excerpts of the operational standards required in this rule that must be included in the owner’s manuals. Operators must not burn unseasoned wood. The use of properly split, stored and seasoned wood has much lower PM emission than high-moisture wood, i.e., green wood or wet wood. Operators must not burn improper fuels such as (1) residential or commercial garbage; (2) lawn clippings or yard waste; (3) materials containing rubber, including tires; (4) materials containing plastic; (5) waste petroleum products, paints or paint thinners, or asphalt products; (6) materials containing asbestos; (7) construction or demolition debris; and (8) paper products; cardboard, plywood or particleboard (Note that best practices do allow the use of fire starters made from paper, cardboard, saw dust, wax and similar substances for the purpose of starting a fire in an affected heater); (9) railroad ties or pressure treated lumber; (10) manure or animal remains; (11) salt water driftwood or other or other previously salt water saturated materials; (12) unseasoned wood; and (13) any materials that are not included in the warranty and owner’s manual for the subject heater or furnace. The owner’s manual and training materials must also educate operators 13681 on the use of proper operating practices, including correct positioning of bypasses and air dampers during startup, normal operation and reloading. Proper practices also include checking air tubes, catalysts (if so equipped), heat exchangers and other critical parts of the heater to ensure they are working properly and are maintained as needed. Best burn operational practices are already highlighted in many manufacturers’ owner’s manuals, educational materials from HPBA and Burn Tips on EPA’s Burn Wise Web site. Numerous comments noted that best work practices and proper operation and maintenance can significantly reduce emissions at reasonable costs. Thus, considering all of the above, the EPA has determined that these work practice and operational standards represent the best systems of emission reduction as required by section 111(h)(1) for the immediate time frame from the effective date until the Step 1 PM emissions limits apply. More discussion of comments on stepped compliance and the EPA’s responses are in section V. Summary of Major Comments and Responses. Table 4 summarizes the PM emissions limits for hydronic heaters and forcedair furnaces that will apply at each step. Note that the emissions standards are ‘‘as measured’’ by the test methods specified in the rule and are labeled as PM although the PM is essentially all PM2.5.

We are allowing an alternative compliance option for manufacturers who choose to certify using cord wood (rather than crib wood) to meet the Step 2 limits for hydronic heaters. The proposal would have required cord wood testing for all Step 2 compliance certifications. Cord wood testing is a better measure of how stoves actually VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 0.93 lb/mmBtu heat output (weighted average). 0.93 lb/mmBtu heat output (weighted average). 0.15 lb/mmBtu heat output for each individual burn rate. perform in home use; however, we are concerned that many manufacturers (over 90 percent are small businesses) do not yet have experience with designing their stoves to perform well with cord wood testing. Numerous hydronic heater manufacturers may not be ready by the Step 2 compliance date and that could result in unreasonable PO 00000 Frm 00011 Fmt 4701 Sfmt 4700 economic impacts. Allowing this option acknowledges the efforts of the industry leaders and encourages others to follow their example. Special (required) permanent and (voluntary) temporary labels for heaters certified with cord wood would specify that they meet a PM emissions limit of 0.15 lb/mmBtu heat output. The Step 2 PM emission E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 13682 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations limit for forced-air furnaces matches the hydronic heater alternate cord wood option emission level of 0.15 lb/mmBtu because CSA B415.1–10 already specifies cord wood for the certification tests. The bases for the emission levels are discussed in section V.B BSER and Particulate Emission Limits for Central Heaters (subpart QQQQ). We are making a single determination of BSER for catalytic, noncatalytic, hybrid, cord wood and pellet heaters and furnaces in order to not restrict open market competition. We are requiring manufacturers to provide warranties on the catalysts, prohibit the operation of catalytic heaters and furnaces without a catalyst and require operation according to the owner’s manual. In addition, we are requiring manufacturers to provide warranties for noncatalytic and hybrid heaters and furnaces and require operation according to the owner’s manual. As discussed at proposal, we considered requiring efficiency standards (heat output divided by fuel input) to ensure that heaters are efficient and burn no more wood than necessary for the heat demand so that the consumers can save money on fuel and so that the emissions are lower. We did not propose an efficiency standard because we concluded we do not yet have sufficient data, but the final rule uses our section 114 authority to require efficiency testing and reporting to the EPA. We will include context and summaries of this information on the EPA Burn Wise Web site. This will help better inform consumers so they can choose the best-performing heaters now that will also save them money on fuel costs and also reduce PM emissions by burning less wood. This will also provide data to states and the EPA as we consider future wood heater rulemaking. At this time, we lack sufficient data to issue a CO emissions limit in today’s final rule. However, this rule uses our section 114 authority to require manufacturers to determine CO emissions during the compliance tests (as typically conducted), report those results to the EPA and include those results on the manufacturer’s Web site. This will help better inform consumers so they can choose the best-performing heaters that have less CO emissions and less health concerns for themselves and their neighbors. This will also provide data to states and the EPA as we consider future rulemaking. We intend to include context and summaries of the submitted CO emissions data on the EPA Burn Wise Web site also. In this final rule, we are not setting limits on visible emissions, and we are VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 not prohibiting use in non-heating seasons. However, operators should note that some state, local and tribal jurisdictions have limits, prohibitions and other requirements that must be followed. Like the subpart AAA requirements, the subpart QQQQ requirements provide additional time for the sale of unsold hydronic heaters manufactured before the compliance date. This additional sell-through time does not include forced-air furnaces because EPA has determined that it is reasonable for forced-air furnace manufacturers to revise their owner’s manuals, training and marketing materials to comply with the work practice and operational standards by the effective date. As in subpart AAA, subpart QQQQ includes a list of prohibited fuels because their use would cause poor combustion or even hazardous conditions. As in subpart AAA, subpart QQQQ requires that the owner or operator must operate the hydronic heater or forced-air furnace in a manner that is consistent with the owner’s manual and the rule requires the manufacturer to discuss the best operating practices in the owner’s manual. For pellet-fueled appliances, operation according to the owner’s manual includes operation only with pellet fuels that are specified in the owner’s manual. As in subpart AAA, manufacturers must only specify graded and licensed pellets that meet certain minimum requirements. Data show that pellet quality is important to ensure that the appliances operate properly such that emissions are within the appliance certification limits. The permanent labeling requirements and owner’s manual requirements in subpart QQQQ are similar to the guidelines in the EPA’s current voluntary hydronic heater program with some improvements. Like in subpart AAA, the temporary labels (hangtags) are voluntary and are only for models that meet Step 2 levels before the compliance date and these hangtags end upon the Step 2 compliance date. Subpart QQQQ also has a cord wood alternative compliance option with a special permanent label and a voluntary temporary label (hangtag) for models that meet Step 2 using cord wood. The structure of the rest of subpart QQQQ is similar to the subpart AAA certification and quality assurance process. 4. Emission Testing, Reporting and Certification The final rule requires that before manufacture and sale at retail, all affected hydronic heaters and forced-air furnaces subject to subpart QQQQ must PO 00000 Frm 00012 Fmt 4701 Sfmt 4700 conduct certification compliance testing, submit a certificate of compliance and receive EPA approval for the Step 1 and Step 2 PM emission limits by the dates shown in Table 4. For hydronic heaters, we are requiring emission testing, reporting and certification based on crib wood to demonstrate compliance with Step 1 and Step 2 emissions limits. The final rule requires crib wood emission testing of hydronic heaters by one of the following methods: EPA Method 28WHH in its entirety or EPA Method 28WHH–PTS (with approved adjustment for crib wood versus cord wood) or ASTM E2618–13 with conditions or European National (EN) test method EN 303–5 with conditions. We note that EPA’s current NSPS general provisions provide that affected sources may request EPA approval of alternative test methods on a case-bycase basis as appropriate. See 40 CFR 60.8(b). Commenters overwhelmingly agreed that tuning heaters for crib wood certification tests often results in poorer performance in homes. Based on the existence of viable draft cord wood test methods and the expectation that the ASTM test methods would be final soon after the NSPS proposal and that significant testing of heaters re-tuned to perform well on cord wood would occur before promulgation of this final rule, the EPA proposed to require testing with cord wood for the Step 2 emissions limits. We still encourage manufacturers to design wood heaters that best represent in-home performance on cord wood that consumers use as soon as possible. However, the ASTM cord wood test methods have not been completed and only limited testing using the draft methods has occurred. We received numerous comments with concerns about when the cord wood test methods would be ready and how quickly heaters could be redesigned to perform well with cord wood certification testing that we proposed for Step 2, i.e., 5 years after the effective date. At proposal, we had limited test data for heaters using cord wood. Considering all of the above, we have determined that we do not have sufficient data at this time to adequately support a regulatory requirement for cord wood testing. We expect that many manufacturers will choose the alternative cord wood compliance testing option so that consumers will have more opportunities to purchase stoves that are tuned for inhome use. We will consider alternative cord wood test method requests on a case-by-case basis until we are convinced that improved test methods E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations have been sufficiently demonstrated that they can be relied upon for regulatory purposes. For now, we will be receptive to alternative test methods requests that use the current ASTM draft methods. We will also be receptive to other alternative test method requests that are adequately demonstrated, ideally according to the EPA Method 301 validation procedures. Additionally, we expect that within the next few years we will receive enough cord wood test data for the EPA to establish revised certification requirements based on cord wood testing. In this final rule, the EPA is relying on the cord wood test method that has been developed by the CSA for forcedair furnaces. The current version of CSA B415.1–10 was published in March 2010, and it includes not only the forced-air furnace test method but also Canadian emission performance specifications for indoor and outdoor central heating appliances. In this final rule, we are relying on efficiency test methods that have been developed by the CSA. The current version of CSA B415.1–10 was published in March 2010. As discussed earlier in section III.B.4 of this preamble, regarding the certification process for room heaters (revised subpart AAA), we are also requiring third-party certifiers for hydronic heaters and forced-air furnaces so as to reduce the potential for certification delays that could result from errors in testing. However, for forced-air furnaces, we are concerned that there may not be sufficient thirdparty certifier capacity specific to forced-air furnace testing according to the CSA B415.1–10 test method and review and approval capacity by the EPA, especially in the first year. We do not want to unfairly restrict the production and sales of forced-air furnace manufacturers who do all the things they should do and then potentially have to wait on EPA approval. Thus, we have added a conditional, temporary approval by the EPA for forced-air furnaces based on the manufacturer’s submittal of a complete certification application. The application must include the full test report by an EPA-approved laboratory and all required compliance statements by the manufacturer. The conditional approval would allow forced-air furnace manufacture and sales for 1 year or until EPA review of the application, whichever is earlier. Within that year, the manufacturer must submit a certificate of conformity by a third-party certifier. VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 The 1-year conditional, temporary approval by the EPA does not apply to hydronic heaters because they have been required to submit third-party certifications for the EPA hydronic heater voluntary partnership program since 2008 and will continue to do so under this NSPS. IV. Summary of Significant Changes Following Proposal This section is a summary of the significant changes from the proposed rule based on the comments and additional material we received and have carefully considered. The reasons for these changes and their potential impacts are in the Response to Comments (RTC) document and are summarized in section V Summary of Major Comments and Responses. A. Best Systems of Emission Reduction/ Particulate Emission Limits We received considerable comment on the proposed PM emission limits that is relevant to our determination of BSER. As explained in more detail in section V, these final emission limits represent significant advances in stove technology and substantial reductions in emissions, both collectively and from individual units. 1. Room Heaters The EPA is changing the proposed Step 2 PM emissions limit for new residential room heaters, including catalytic and noncatalytic adjustable rate wood heaters, single burn rate wood heaters and pellet heaters/stoves from 1.3 g/hr to 2.0 g/hr using crib wood. Compliance for room heaters will be determined using the weighted average of burn rates rather than requiring each individual burn rate to meet the limit. To reduce potential certification delays and unnecessary costs for small businesses, we are adding an automatic Step 1 EPA approval for models with valid EPA certifications under the 1988 NSPS that show that the models achieve the Step 1 emission levels. Manufacturers may choose to test using either crib wood or cord wood. If the manufacturers choose the cord wood alternative compliance option, the PM emission limit for cord wood is 2.5 g/ hr. Although the number is higher, the cord wood test method is more reflective of fuel that is used in homes and the data available to the EPA indicate that this PM emission level is at least as stringent as the 2.0 g/hr primary crib wood testing emission limit. More details on this are in section V.A Summary of Major Comments and Responses. PO 00000 Frm 00013 Fmt 4701 Sfmt 4700 13683 For wood heater/stove certification tests using cord wood, the EPA is allowing (voluntary) manufacturers to use a special EPA label which recognizes that cord wood testing more closely reflects actual in-home use. 2. Central Heaters: Hydronic Heaters and Forced-Air Furnaces For new residential hydronic heaters, the final rule keeps the proposed Step 1 weighted average PM emission rate of 0.32 lb/mmBTU heat output, establishes a Step 1 PM emissions cap of 18 g/hr for any individual test run and adds automatic Step 1 EPA certification for hydronic heater models if they are already qualified as meeting the Phase 2 emissions level of the EPA’s voluntary program. The change from the proposed Step 1 cap of 7.5 g/hr to the final rule Step 1 cap of 18 g/hr was to match the Phase 2 emission levels of the EPA voluntary program and reduce potential certification delays. To further reduce potential certification delays and unnecessary costs for small businesses, we are also adding automatic Step 1 EPA certification for hydronic heater models certified by NYSDEC that demonstrate the models achieve the Step 1 levels and RHNY-qualified pellet hydronic heaters. Similarly, we are adding automatic Step 1 EPA certification for new forced-air furnaces that are independently certified (i.e., not self-tested) under CSA B415.1–10 to meet the Step 1 emission level or that are certified by NYSDEC and meet the Step 1 emission level. For forced-air furnaces for Step 1, we deleted the 7.5 g/hr particulate emission limit per individual burn rate because the CSA B415.1–10 certifications are based on the weighted average, not the g/hr limit, and because the manufacturers do not have experience with meeting g/hr limits for these furnaces. For hydronic heaters, we are changing the proposed Step 2 PM emissions limit of 0.06 lb/mmBtu heat output to 0.10 lb/ mmBtu heat output for each individual burn rate, tested on crib wood. Manufacturers may choose to test using either crib wood or cord wood. If the manufacturer chooses the cord wood alternative compliance option, the Step 2 PM emission limit for cord wood is 0.15 lb/mmBtu heat output. Although the number is higher, the cord wood test method is more reflective of the fuel that is used in homes and the limited cord wood data available to the EPA indicate that this PM emission level is at least as stringent as the 0.10 lb/ mmBtu heat output crib wood testing emission limit. For forced-air furnaces, the Step 2 PM emission level matches the hydronic heater cord wood E:\FR\FM\16MRR2.SGM 16MRR2 13684 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations alternative option because forced-air furnaces are certified using CSA B415.1–10, which already specifies cord wood as the test fuel. Details on the bases of the emission levels are in section V, Summary of Responses to Major Comments. For hydronic heaters and forced-air furnaces tested with cord wood, the EPA is allowing (voluntary) manufacturers to use special permanent labels and EPA temporary labels (hangtags) which recognize that cord wood testing more closely reflects actual operation under in-home-use conditions. mstockstill on DSK4VPTVN1PROD with RULES2 3. Masonry Heaters As stated in section III of this preamble, the EPA is not taking final action on proposed subpart RRRR for new residential masonry heaters at this time. Comments indicated that the Masonry Heater Association (MHA) needs more time to finish their efforts to develop revised test methods, alternative compliance calculation procedures and dimensioning procedures. The MHA comments stated that the cost of testing masonry heaters is high and impractical because almost all are custom-built onsite. After we receive additional information from MHA and others, we will consider if we should take final action for new residential masonry heaters in a future rulemaking. The potential emission impact of this delay is small. Fewer than 1,000 masonry heaters are built each year. Most manufacturers build fewer than 15 heaters per year. The total nationwide annual emissions are estimated to be less than 10 tons of PM2.5. B. Appliance Certification, Laboratory Accreditation and Third-Party Certification In section III.D of the preamble to the proposed rule, we described the proposed approach for a third-party certification program by an ISOaccredited certifying body and testing by ISO-accredited testing laboratories. This approach requires manufacturers to use third-party, independent ISOaccredited and EPA-approved test labs and certifying entities to demonstrate compliance with a representative appliance for a model line. Under the Administrator Approval Process (see § 60.533(c) of the proposed rule), we proposed a transition period of 1 year from the effective date of the final rule for test labs to receive ISO accreditation through an EPArecognized accreditation body. In this final rule, we are increasing the transition period for test laboratories VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 that are currently EPA-accredited from 1 year to 3 years from the effective date of this final rule (i.e., until May 15, 2018). This additional time for test laboratory accreditation will reduce concerns about costs for these small laboratories and potential testing delays. We proposed that certifying entities be required to receive ISO accreditation upon the effective date of the final rule; however, commenters stated that ISO accreditations can take 6 months. Requiring use of ISO-accredited certifying bodies/entities on the effective date of the final rule can be difficult for small manufacturers of wood stoves/heaters and forced-air furnaces, which previously have not been required to obtain certifications from ISO-accredited certifying bodies/ entities; therefore, we are allowing a 6month transition for models other than hydronic heaters. The 6-month transition period does not apply to hydronic heaters because the use of ISOaccredited certifying bodies/entities has been part of the EPA’s voluntary partnership program for hydronic heaters since 2008. C. Cost and Economic Impacts Cost and economic impacts of the proposed rule have been revised to reflect changes to the standards and improved estimates of costs and emissions for room heaters and central heaters. See section VI of this preamble for a discussion of these revised impacts, as well as the RIA and the RTC document for this final rule for more detailed information. D. Test Methods and Compliance Certification Calculation Procedures The EPA proposed a number of changes to test methods established under the 1988 rule to improve their precision and to better reflect real-world conditions. 1. Burn Rates in Compliance Certification Calculations For Step 2 emission limits, we proposed to require certification compliance at the lowest burn rate (Category 1) and the maximum burn rate (Category 4) rather than the weighted average of the four burn rates, which was required in the 1988 rule. Many comments on the proposal and the data in the NODA strongly supported the proposed compliance determinations per individual burn rates. Many other comments strongly opposed the proposal. Considering all of the comments and focusing on the available test data, especially the EPA wood stove certification test data by burn rate that we included in the July PO 00000 Frm 00014 Fmt 4701 Sfmt 4700 1, 2014, NODA, we are requiring certification calculations based on the weighted average of the four burn rates for subpart AAA. More detail is presented in section V.A, BSER and Particulate Emission Limits for Room Heaters (revised subpart AAA), and section V.F, Test Methods. For subpart QQQQ, the final rule uses the weighted average with a cap for each test run for Step 1 (for hydronic heaters), but retains the proposed requirement for compliance at each burn rate for Step 2 (for both hydronic heaters and forced-air furnaces), given concerns about the sometimes very large emissions at individual burn rates. The emission limits reflect the data available. For a more detailed discussion of these comments and responses, see the RTC document in the docket for this rule. 2. Cord Wood Test Method Based on the existence of viable draft cord wood test methods and the expectation at proposal that the ASTM ‘‘real world’’ test methods for cord wood would be complete soon after the NSPS proposal and that significant testing of wood heaters re-tuned to perform well on cord wood would occur before promulgation of this final rule, the EPA proposed to require testing only with cord wood for compliance with Step 2 emissions limits. We still encourage manufacturers to design wood heaters that perform best on cord wood that consumers use. However, the ASTM cord wood test methods have not been completed and only limited testing using the draft methods has occurred. We received numerous comments from noncatalytic stove manufacturers and laboratories and some states with concerns about when the cord wood test methods would be ready and how quickly noncatalytic stoves could be redesigned to perform well with cord wood certification testing that we proposed for Step 2, i.e., 5 years after the effective date. (We had test data for three catalytic or hybrid wood heaters/ stoves that performed very well on cord wood at the time of proposal.) However, considering all of the above, we have determined that we do not have sufficient data at this time to support a regulatory requirement for cord wood testing (other than for forced-air furnaces), but rather will allow an alternative compliance option for cord wood testing. (Note that forced-air furnace certification tests are conducted according to CSA B415.1–10 which has specified cord wood as the test fuel since 2010.) We expect that many manufacturers will choose the alternative cord wood E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations compliance testing option so that consumers will have more opportunities to purchase stoves that are tuned for use in the ‘‘real world.’’ We will consider alternative cord wood test method requests on a case-by-case basis until we are convinced that improved test methods have been sufficiently demonstrated that they can be relied upon for regulatory purposes. For now, we will be receptive to alternative test methods requests that use the current ASTM draft methods. Also, we will be receptive to other alternative test method requests that are adequately demonstrated, ideally according to the EPA Method 301 validation procedures. Additionally, we expect that within the next few years we will receive enough cord wood test data for the EPA to establish revised certification requirements based on cord wood testing. See section III of this preamble for the specific alternative compliance emissions limit options we are allowing under subparts AAA and QQQQ for manufacturers of heaters who choose to certify compliance with cord wood instead of crib wood. The bases for the options are discussed in section V, Summary of Responses to Major Comments. mstockstill on DSK4VPTVN1PROD with RULES2 3. Additional Test Methods Based on comments and the need to minimize potential testing and certification delays for Step 1, the final rule includes additional test methods for hydronic heaters. In addition to the proposed use of EPA Method 28WHH and EPA Method 28WHH–PTS, the final rule allows manufacturers to use ASTM E2618–13 and EN303–05 with specified conditions/adjustments (e.g., burn rate categories to better match EPA Method 28WHH and use of thermal storage) for determining compliance with the Step 1 emission limits. As with all NSPS, manufacturers may request EPA approval of alternative test methods on a case-by-case basis. See 40 CFR 60.8. E. Sell-Through of Inventory Based on numerous comments from small business manufacturers and small business retailers and some states, we are lengthening the retail sell-through period for subpart AAA from 6 months from the effective date of the final rule to December 31, 2015, approximately 8 months from the expected effective date. That is, no manufacturer, distributor, wholesaler or retailer may sell or offer to sell new stoves after December 31, 2015, that do not meet the Step 1 emission limit. Eight months will better cover the primary selling period after the rule is final and will affect a very VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 small number of appliances. We are also providing a retail sell-through period for subpart QQQQ hydronic heaters to also cover the primary selling period. We are not allowing a retail sell-through period for forced-air furnaces because the manufacturers and retailers can quickly revise the owner’s manuals to add best burn practices to comply with the work practice and operational standards. These sell-through provisions do not affect resale of used stoves/heaters; such resale is not restricted by this rule. F. Appeals and Administrative Hearing Procedures Based on the public comments and our additional review of the history of the 1988 rule, we have determined that there is no need to make the proposed change to a streamlined Petition for Review process. Therefore, we are retaining the Appeals and Administrative Hearing Procedures outlined in the 1988 rule. V. Summary of Responses to Major Comments Detailed summaries are in the RTC document in the docket. A. BSER and Particulate Emission Limits for Room Heaters (Revised Subpart AAA) We received a full range of comments on the proposed BSER and emission limits for room heaters and the data in the July 1, 2014, NODA. Many comments agreed completely with our proposal and that approximately 10,000 tons/yr of PM2.5 emission reduction is very important and would lead to significant improvement in public health protection. Some comments indicated that bans of wood burning would be more appropriate. The EPA is not banning wood burning in this rule because section 111(a)(1) of the CAA requires that the emission standards reflect the degree of emission limitation achievable by the application of BSER. Some comments suggested that we develop less stringent standards for rural areas than other areas or no standards in rural areas at all. The EPA is not setting different emission standards for rural areas because section 111 of the CAA does not provide legal authority for differentiated standards based on where the devices are used. 1. Stringency of Step 2 Level Using Cord Wood for Room Heaters Many noncatalytic stove manufacturers and laboratories and some other manufacturers were concerned especially about the stringency of the Step 2 level using cord PO 00000 Frm 00015 Fmt 4701 Sfmt 4700 13685 wood 5 years after the effective date. We considered all comments and focused on those that discussed the emission data in detail. Numerous small business manufacturer comments suggested that (1) current stove designs are focused on burning crib wood well at the expense of burning ‘‘real world’’ cord wood well, and stoves cannot just be tweaked to burn both well; (2) experience in homes is that some crib wood-certified stoves smolder if the homeowner does not operate them at high burn for at least 30 minutes before dampening down to the low burn rate settings; (3) a cord wood test method more representative of inhome use should be developed as soon as possible; and (4) a voluntary option should be used to establish a cord wood database to determine BSER. As discussed in the NODA, limited cord wood testing by Brookhaven National Laboratory (BNL), under contract to the EPA, showed that repeatability of the cord wood test method results can sometimes be very good (i.e., within 15 percent). However, the results of the BNL cord wood tests also showed that emissions from a popular, inexpensive, current-model noncatalytic stove that was not adjusted by the manufacturer for burning cord wood instead of crib wood during the certification test can be much higher than (in several cases, over twice as high) the crib wood emission test results. Other comments suggested that we stay with the proposed cord wood testing requirement and proposed Step 2 emission level that some heaters can already meet. For example, Washington State Department of Ecology (WSDOE) stated that (1) the data show that hybrid stoves are the best technology capable of meeting Step 2, better than noncatalytic stoves; and (2) the extensive lack of Category 1 burn rate data in the certification tests indicates a ‘‘serious flaw’’ and that EPA needs to develop test methods more representative of inhome use that include start-up and the lowest burn rate at which a device may be commonly operated. We agree with WSDOE that it appears that hybrid stoves may be the best technology capable of meeting Step 2, better than noncatalytic stoves; however, we are concerned about setting required emission levels that may have potential impacts on a large number of small businesses that may not yet have much experience with that technology, and we do not want to prematurely restrict their choices. As discussed in section IV.D, we agree that test methods are needed that better reflect in-home use and include start-up and the lowest burn E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 13686 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations rate at which a device may be commonly operated. As discussed earlier in this preamble, based on the data and comments, we have determined that it is premature to require a cord wood-based Step 2 emission limit at this time. Rather, we are basing the Step 2 requirements on crib wood testing and including an alternative compliance option to encourage manufacturers to certify with cord wood as soon as possible to provide consumers with better information regarding in-home use. In support of the cord wood alternative compliance option, there are three stove model lines that meet Step 2 using cord wood testing. As discussed in section IV.D of this preamble, we expect additional manufacturers will choose the alternative cord wood compliance testing option so that consumers will have more opportunities to purchase stoves that are tuned for inhome use. We will consider alternative cord wood test method requests on a case-by-case basis until we are convinced that improved test methods have been sufficiently demonstrated that they can be relied upon for regulatory purposes. For now, we will be receptive to alternative test method requests that use the current ASTM draft methods. We will also be receptive to other alternative test method requests that are adequately demonstrated, ideally according to EPA Method 301 validation procedures. We expect that within the next few years we will receive enough cord wood test data for the EPA to establish revised certification requirements based on cord wood testing. Commenters overwhelming agree that cord wood testing is a better representation of ‘‘real world’’ conditions, provides better information for consumers to choose the cleanest and most efficient heaters and that the EPA should encourage cord wood testing. Thus, the final rule includes a cord wood alternative compliance option for Step 2 and special permanent labels and allows (voluntary) temporary EPA labels (hangtags) for units tested with cord wood. As discussed earlier in this section, the proposal reasonably anticipated that all manufacturers would iteratively adjust the combustion air flows, directions and proportions to better match the change in hydrocarbon volatilization rate due to the difference in surface-area-to-volume ratio and spacing for crib wood versus cord wood. The proposal also reasonably anticipated that manufacturers would have a full complement of cord wood tested heaters available by Step 2, i.e., 5 years after the effective date. Some VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 stoves already perform well on cord wood. However, comments from some small business noncatalytic stove manufacturers, small business laboratories and some states have questioned whether most small business manufacturers could comply with the Step 2 emission limits based on cord wood by that date. As discussed in the NODA, the cord wood test data submitted to us for three catalytic or hybrid wood stoves manufactured by two small businesses show that their EPA-certified wood stoves (when tested using cord wood and making no design changes to adjust for testing using cord wood versus crib wood) have similar emissions as their stoves do when tested using crib wood. The cord wood results show that they can achieve an emission limit of 1.3 g/hr, as proposed. Several comments stated that they did not believe these results are representative of most EPA-certified stoves and that typical cord wood values are likely to be higher than the 1.3 gr/hr level, as well as the 2.0 g/hr level of the final crib wood Step 2 emission level or any other crib wood level. Recognizing that the cord wood alternative compliance option is an option rather than a requirement, we have set the cord wood Step 2 emission level at 2.5 g/hr as the alternative compliance option for room heaters for the following reasons: • Test data show that at least three wood stoves meet a limit of 1.3 g/hr, which (coupled with some commenters’ claims that the test precision is no better than 1.0 g/hr) would suggest an achievable limit on the order of 2.3 g/hr. • The State of Washington DOE has required catalytic stoves since 1995 to meet a limit of 2.5 g/hr. • The Step 2 emission level does not take effect until 5 years after the effective date of this final rule. The cord wood alternative compliance option provides appropriate opportunities to small manufacturers who have been leaders in optimizing for cord wood performance and encourages other manufacturers to follow their example. More discussion is in the RTC document in the docket for this final rule. 2. Stringency of Step 2 Level Using Crib Wood for Room Heaters We have set the crib wood Step 2 emission limit at 2.0 g/hr for the following reasons: • Focusing on the comments that discussed the details of the crib wood certification test data for Step 2, nearly 90 percent of current catalytic/hybrid stoves and over 18 percent of current PO 00000 Frm 00016 Fmt 4701 Sfmt 4700 noncatalytic stoves would meet the Step 2 emission limit of 2.0 g/hr in the final rule. This compares to 20 percent of catalytic/hybrid wood heaters/stoves and only 3 percent of noncatalytic wood heaters/stoves for the proposed 1.3 g/hr Step 2 emission limit. • Considering that current stove sales are approximately 20 percent catalytic/ hybrid stoves and 80 percent noncatalytic stoves, the estimated impact of adjusting the Step 2 emission level from 1.3 g/hr to 2.0 g/hr will be to decrease the emission reduction estimated for this rule by approximately 36 tons per year, which is relatively small compared to the rule’s total estimated emission reduction of 8,269 tons per year. Furthermore, the impact for any individual stove is only on the order of 2 pounds per year. • The final Step 2 emission limit of 2.0 g/hr is more stringent than any current state requirement. Thus, considering the significant emission reductions for this final rule and the potential significant cost impacts for this industry that is comprised of over 90 percent small businesses, and considering that the difference between the proposal and this final rulemaking is less than approximately 36 tons per year compared to the 8,269 tons per year for this final rulemaking, we judge that a final Step 2 emission level of 2.0 g/hr within 5 years as BSER for room heaters is a reasonable balance of environmental impacts and costs. 3. Determination of BSER for Room Heaters Some comments questioned that BSER is adequately demonstrated. The data in the paragraph above show that not only are the emission levels demonstrated, the percentages of current heaters that already meet Step 2 demonstrate the reasonableness of the Step 2 emission limit, especially considering that the Step 2 emission limit becomes applicable 5 years after the effective date. Some comments recommended that the final rule be as stringent as the cleanest stoves on the market and some comments suggested numbers that reflect the top 5 percentile. Section 111 of the CAA does not specify any particular floor for BSER determinations but does require consideration of costs. As discussed above, considering that the emission reduction difference between the proposal and this final rulemaking is approximately 36 tons per year (compared to the 8,269 tons per year for this final rulemaking), we judge that a final Step 2 BSER of 2.0 g/hr within 5 E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations years is a reasonable balance of environmental impacts and costs. Some comments suggested that the precision of the test method is not good enough to set emission limits more stringent than the 1988 NSPS. In response, we note that the State of Washington DOE has successfully required a 2.5 g/hr emission limit for catalytic stoves since 1995, and several stoves have been EPA-certified at 1.0 g/ hr, which is well under the final Step 2 emission limit of 2.0 g/hr. Even if the commenters’ claims were correct that the precision is no better than 1.0 g/hr, the final emission limit of 2.0 g/hr would still cover these stoves, i.e., 1.0 g/hr plus 1.0 g/hr equals 2.0 g/hr, the step 2 emission limit. Further, we note that the final rule deletes the previously required upward adjustment for Method 5G to 5H, which was sometimes over a 30 percent increase for certification values (under the 1988 NSPS and the State of Washington DOE) that were tested using Method 5G. mstockstill on DSK4VPTVN1PROD with RULES2 B. BSER and Particulate Emission Limits for Central Heaters (Subpart QQQQ) Comments of many small business manufacturers of hydronic heaters and forced-air furnaces questioned the demonstrations of BSER for hydronic heaters and forced-air furnaces, especially the proposed cord wood Step 2 limit of 0.06 lb/mmBtu. As discussed earlier in sections III.B and III.C of this preamble, considering the numerous comments expressing concern about whether most small business manufacturers will be ready in time, reviewing the data currently available, and acknowledging that the expected ASTM cord wood test methods are not yet completed at this time, we have determined that it is premature to require cord wood certification tests for hydronic heaters at this time. Rather, we are allowing a cord wood alternative compliance option. 1. Stringency of Step 1 Level Using Crib Wood for Central Heaters Focusing on the crib wood test primary requirement and crib wood test data, we see that there are already 50 hydronic heater models Phase 2 qualified under the EPA hydronic heater voluntary partnership program, which also meet the Step 1 emission levels of this final NSPS. These models will be automatically deemed EPA-certified for Step 1 of this final NSPS. (There are also 19 voluntary program qualification tests recently submitted to the EPA that, if valid, will result in 19 additional Phase 2 model qualifications.) Similarly, models certified by the NYSDEC that comply with Step 1 will also be VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 automatically deemed EPA certified until Step 2. Also, over 20 pellet heaters/boilers are already qualified under the RHNY program, and they will be automatically deemed to be EPAcertified for Step 1 provided they comply with the RHNY requirements for installation and operation with adequate thermal storage. That is, no additional certification will be necessary for these three groups for Step 1. For forced-air furnaces, commenters indicated that the Step 1 p.m. emission limit was achievable but small furnaces needed 1 year and large furnaces needed 2 years to complete the certification testing. As discussed earlier, the final rule incorporates the necessary additional time for testing. 2. Stringency of Step 2 Level Using Crib Wood for Central Heaters For new residential hydronic heaters, we have set the crib wood Step 2 emission level at 0.10 lb/mmBtu based on the following: • Looking at the crib wood test primary requirement for Step 2 (0.10 lb/ mmBtu), 9 of the 50 (18 percent) EPAqualified hydronic heater models currently achieve Step 2 on crib wood (per run); and all 20 of the RHNYqualified models achieve 0.10 lb/ mmBtu. • The proposed Step 2 level (0.06 lb/ mmBtu) currently is achieved only by 3 of the 49 (6 percent) EPA-qualified models (per run). • The emission reduction difference between the proposed Step 2 hydronic heater emission level (0.06 lb/mmBtu) and the final Step 2 hydronic heater emission level (0.10 lb/mmBtu) is approximately only 15 tons per year (compared to the 8,269 tons per year for this final rulemaking). Considering the potential significant cost impacts for this industry that is comprised of over 90 percent small businesses, and that the relatively small difference in emission reductions between the proposal and this final rulemaking, we judge that a final hydronic heater Step 2 emission level of 0.10 lb/mmBtu within 5 years as BSER is a reasonable balance of environmental impacts and costs. 3. Stringency of Step 2 Level Using Cord Wood for Central Heaters As with room heaters (subpart AAA) and for the same reasons, hydronic heaters (subpart QQQQ) have a cord wood alternative compliance option. Considering that it is an option designed to encourage leadership for others to follow, that it is an option rather than a requirement and that many European models already achieve levels better PO 00000 Frm 00017 Fmt 4701 Sfmt 4700 13687 than 0.06 lb/mmBtu, we have determined that 0.15 lb/mmBtu within 5 years as the cord wood alternative compliance option is a reasonable balance of environmental impacts and costs. We note that the RHNY emission qualification requirement is 0.08 lb/ mmBtu. Further, we note that even if there were to be method uncertainty on the order of approximately four times the expected precision of 35 percent, models at 0.06 lb/mmBtu would still be included. We have set the same final Step 2 emission level for forced-air furnaces as BSER as we have for hydronic heaters based on the following: • The emission reduction difference between the proposed forced-air furnace Step 2 emission limit of 0.06 lb/mmBtu and this final rulemaking (0.15 lb/ mmBtu) is approximately 40 tons per year (compared to 8,269 tons per year emission reduction for this final rulemaking). The difference is slightly larger for forced-air furnaces compared to hydronic heaters because the annual sales of forced-air furnaces are much larger (i.e., 41,000 versus 13,000). • We considered the potential significant cost impacts for this industry that is comprised of over 90 percent small businesses, as well as the modest difference between the environmental impacts of the proposal and this final rulemaking. Therefore, for forced-air furnaces, we judge that a final Step 2 emission level of 0.15 lb/mmBtu within 5 years as BSER is a reasonable balance of environmental impacts and costs. Since forced-air furnaces and indoor hydronic heaters compete in the same market, wise consumers expect similar performance. We expect most forced-air furnace manufacturers to transfer technology and knowledge from wood stoves and hydronic heaters. Some small forced-air furnaces have already transferred technology from wood heaters to achieve good performance. Several industry comments questioned their ability to transfer technology from hydronic heaters because of their concerns about size limitations in order to install forced-air furnaces indoors going through doorways and other entrances to basements. They were especially concerned that the space limitations may affect their ability to adequately insulate the models that may be installed in close proximity to combustibles. We acknowledge their concerns but note that coal, oil and natural gas forced-air furnaces and indoor hydronic heaters that have similar space limitations and proximity to combustibles conditions have successfully handled those concerns for many years. For example, numerous E:\FR\FM\16MRR2.SGM 16MRR2 13688 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations cord-wood-fired indoor hydronic heaters have been safely installed without large volumes of thermal insulation around the firebox mstockstill on DSK4VPTVN1PROD with RULES2 C. Appliance Certification Many comments stressed the importance of easy public availability of certification test reports (especially electronically), limited CBI claims, more details on the EPA Web sites, better labels and more outreach to encourage change outs to cleaner stoves. We agree with these comments and the final rule incorporates this transparency and consumer-friendliness. Some comments suggested wording clarifications that we have incorporated in the final rule. More details are in the RTC document included in the docket for this rule. D. Laboratory Accreditation, ThirdParty Certification and Administrative Approval Process Many comments stressed the importance of credible data for the certifications and the value of close EPA oversight, notwithstanding the addition of ISO-accredited laboratories and ISOaccredited certifying entities. Some comments suggested that the EPA should allow the ISO-accredited certifying entities to issue NSPS certificates directly and that the EPA’s role should be solely to review the certifications and only question their certificates upon cause. The small business laboratories requested more time for the transition to ISOaccreditation because of the cost. As discussed earlier in this preamble, the final rule allows a 3-year extension of current EPA accreditations of laboratories and allows 6 months for ISO accreditation of certifying entities, except for hydronic heaters, which have used ISO-accredited certifying entities since October 2008 for the EPA voluntary program. The EPA will retain its approval and oversight functions for this final rule. As also discussed earlier in this preamble, to address the possibility that there may not be sufficient third-party certifier capacity and review and approval capacity by the EPA, especially in the first year, and so as to avoid unfairly restricting the production and sales of manufacturers who do all the things they should do and then potentially have to wait on the EPA approval, we have added a conditional, temporary approval by the EPA for room heaters subject to revised subpart AAA, as well as forced-air furnaces subject to subpart QQQQ, based on the manufacturer’s submittal of a complete certification application. The application must include the full test report by an EPA-accredited VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 laboratory and all required compliance statements by the manufacturer. The conditional approval would allow manufacture and sales for 1 year or until EPA review of the application, whichever is earlier. Within 1 year, the manufacturer must submit a certificate of conformity by a third-party certifier. The 1-year conditional, temporary approval by the EPA does not apply to hydronic heaters because they have used third-party certifications for the voluntary program since 2008 and will continue to do so under the NSPS. E. Costs and Economic Impacts 1. Costs Comments received on the proposed rule included information and opinions regarding the EPA wood heater cost estimates.8 Comments ranged from criticism that the EPA overestimated costs to criticism that the EPA underestimated costs. The comments that provided data and/or analysis explaining why the commenter thought EPA had not accurately estimated the costs were most persuasive, and we have revised our cost estimates based on those detailed comments. Details of our responses to cost comments are in the RTC document and the technical cost memoranda in the docket for this final rule. a. Room Heaters For example, Washington State Department of Ecology stated that the proposal cost estimates were overestimates and that our estimates did not address input from Woodstock Soapstone Stoves, winner of the 2013 Wood Stove Decathlon, which estimates that the cost of new product development is approximately $200,000, and furthermore that the proposal cost estimates did not address the economies manufacturers realize when they develop functionally identical models from the originally certified model.9 Some other commenters generally stated that EPA’s breakdown of cost estimates faced by manufacturers is inaccurately low. We have considered all the comments and have revised our cost estimates based on comments that provided additional detailed cost data. Prior to proposal, we heard various estimates of the costs to bring a wood heater from concept to completion, from 8 Comments on the proposed NSPS are available electronically through https://www.regulations.gov by searching Docket ID EPA–HQ–OAR–2009–0734. 9 Comment on the proposed rule to Docket EPA– HQ–OAR–2009–0734 from the Washington State Department of Ecology; available at https://www. regulations.gov/#!documentDetail;D=EPA-HQ-OAR2009-0734-1397. PO 00000 Frm 00018 Fmt 4701 Sfmt 4700 $200,000 for a single model to $1,360,000 for a 4-firebox model line. For example, a Hearth and Home article estimated the total cost to bring a model from conception to market as $645,000 to $750,000 for steel stoves and over $1 million for cast-iron, enameled wood stoves. The authors indicated that costs would decrease for separate models in the same line by up to 25 percent. Based on this information, we estimated that a 4-model steel line would cost up to $328,125 per model to develop. These costs include marketing, design, developing first generation, second generation and prototype units; NSPS and safety testing, equipment tooling, etc.10 Two other manufacturers also provided estimated development costs for a 4-box model line, and based on that information at proposal we estimated average costs to develop a new model line, including testing with both crib wood and cord wood and reporting and recordkeeping, of $356,250 for certified wood stoves and pellet stoves. We also estimated $356,250 for single burn rate stoves, forced-air furnaces and hydronic heaters. The Hearth Patio and Barbecue Association (HPBA) provided detailed estimates of adjustable burn rate wood stoves and hydronic heater model development costs. According to HPBA, the proposal cost estimates are deficient because they do not reflect specific emission rates or emission performances. Their detailed wood stove cost estimates are located in Attachment 2 of the HPBA comments and were prepared by National Economic Research Associates (NERA) Economic Consulting (May 2014).11 Appendix A of the document, Woodstove Cost Modeling (prepared by Ferguson, Andors & Company) contains the detailed cost estimates we reviewed and adapted for this analysis.12 The Ferguson analysis provides cost estimates for four categories of emission reductions based on the proposed emission levels, consisting of modifying 7.5 g/hr stoves to comply with a new 4.5 g/hr emission limit, modifying the 4.5 g/ hr stoves to comply with new emission limits of 2.5 g/hr or 1.3 g/hr stoves, and 10 James E.

The resulting cost components consisted of capital costs per model (R&D, engineering labor, tooling, equipment integration, preliminary testing, and other costs to design and manufacture the modified wood stove model) and other fixed costs per model (certification testing and safety testing, roll-out of the modified products including store display models and burn programs, brochures, user manuals, training and product discounts). The mid-point capital costs presented by Ferguson range from $281,725 to $532,050 depending on the emission reduction range.13 As discussed earlier in section III.A, unlike the proposed rule, the final subpart AAA rule only contains a Step 1 PM emission limit of 4.5 g/hr and a Step 2 PM emission limit of 2.0 g/hr, with no alternative, three-step emission limits. The comments overwhelmingly indicated that the three-step emission limit approach was inferior not only environmentally but also economically because it would, in effect, require many small manufacturers to engage in two rounds of R&D rather than one in order to obtain the same eventual endpoint. The Step 1 cost for 7.5 to 4.5 g/hr is a reasonable representation of model development costs for all models subject to subpart AAA, with some exceptions, described below. The Ferguson analysis shows that several of the cost components are identical across scenarios. The analysis claims, however, that other cost components vary according to the specified emission reduction scenario. These differences were not supported in the comments. For purposes of this analysis, we used the 7.5 to 4.5 g/hr scenario as a baseline case and modified it to reflect the deletion of cost categories that were inappropriate for the NSPS analyses, e.g., costs for trips to industry trade shows that would occur for all products regardless of the NSPS. We did accept the assumptions and logic related to evaluating the tooling cost difference between steel stoves and cast iron stoves, as both are commonly manufactured. Like Ferguson, we used an average of their tooling costs to reflect product differences, even though this may overestimate the number of cast iron stoves in the market place. While we recognize the range in capital cost estimates provided both prior to and after proposal of the draft standards 13 Ferguson, Robert (Ferguson, Andors & Company), prepared for the Hearth, Patio & Barbecue Association.

For the final cost analysis, we used the mean wood stove costs. For our analyses, these model development costs represent feasible costs for adjustable burn rate stoves and pellet stoves. For single burn rate stoves, as we did at proposal, the analyses reflect that additional R&D may be required to bring these stoves to qualifying levels. Rather than doubling the total model development costs during the first 2 years as we did at proposal, the new costs for the R&D/Engineering cost portion of the total costs are doubled in the first 2 years, with ‘‘normal’’ model development proceeding thereafter. Details of our responses to cost comments are in the RTC document and the technical and cost memoranda in the docket for this final rule. b. Central Heaters At proposal, our analyses reflected that hydronic heaters and forced-air furnaces would face the same model development costs as room heaters. Some commenters objected to this characterization, particularly based on the detailed hydronic heater cost estimates located in Attachment 3 of the HPBA comments as prepared by NERA Economic Consulting (May 2014).14 Appendix A of that document, Hydronic Heater Cost Modeling (prepared by Ferguson, Andors & Company) contains the detailed cost estimates we reviewed and adapted for this analysis. The HPBA costs for hydronic heaters were prepared with the same methodology and overall assumptions as they used in development of the wood heater costs. The Ferguson analysis provides cost estimates for four categories of hydronic heater emission reductions, based on the proposed emission levels consisting of modifying uncontrolled heaters to comply with a new 0.32 lb/mmBtu emission limit, modifying the 0.32 lb/mmBtu heaters to comply with new emission limits of 0.15 or 0.06 lb/mmBtu, and modifying a 0.15 lb/mmBtu heater to a new emission limit of 0.06 lb/mmBtu. The resulting cost components consisted of capital costs per model (R&D, engineering labor, tooling, equipment integration, preliminary testing, and other costs to design and manufacture 14 Comment on the proposed rule to Docket EPA– HQ–OAR–2009–0734 from the HPBA available at https://www.regulations.gov/#!documentDetail;D= EPA-HQ-OAR-2009-0734-1643.

The mid-point capital costs presented by Ferguson range from $1,743,750 to $2,162,300 depending on the emission reduction range.15 We used these cost estimates in our analysis. As discussed earlier in section III.A, unlike the proposed rule, the final rule contains a Step 1 PM emission limit of 0.32 lb/mmBtu and a Step 2 PM emission limit of 0.10 lb/mmBtu, with no alternative three-step PM emission limits. The comments overwhelmingly indicated that the three-step PM emission limit approach was inferior not only environmentally but also economically because it would, in effect, require many small manufacturers to engage in two rounds of R&D rather than one in order to obtain the same eventual endpoint. The Step 1 PM emission limit cost for modifying uncontrolled heaters to comply with 0.32 lb/mmBtu is a reasonable representation of model development costs for all models subject to subpart QQQQ, with some exceptions, described below. The Ferguson analysis shows that several of the cost components are identical across scenarios. The analysis claims that other cost components vary according to the specified emission reduction scenario; however, no support was provided for these claims in the Ferguson analysis. For purposes of our analysis, we used the scenario of uncontrolled to 0.32 lb/ mmBtu as a baseline case and modified it to reflect the deletion of cost categories that were inappropriate for the NSPS impact analyses, e.g., costs for trips to industry trade shows that would occur for all products regardless of the NSPS. For our final rule cost analysis, we used the mean hydronic heater costs estimated in Table 5–2 of the final RIA. These model development costs represent feasible costs for hydronic heaters. For forced-air furnaces, as we did at proposal, our analysis included the additional R&D that may be required to bring these heaters to qualifying levels. Rather than doubling total model development costs during the first 2 years as we did at proposal, for the final rule analysis the R&D/Engineering cost portion of the total costs are doubled in 15 Ferguson, Robert (Ferguson, Andors & Company), prepared for HPBA.

Economic Impacts As discussed in detail in the RIA and summarized in section D.1 above, we received numerous comments on the costs, and we have adjusted our cost estimates as appropriate. Since the economic impacts are based on the costs and other factors, we have adjusted the economic impacts accordingly. The details of the adjustments are in the RIA, and a summary is in sections IV.C and VI of this preamble. F. Test Methods mstockstill on DSK4VPTVN1PROD with RULES2 1. Crib Wood vs. Cord Wood We received a full range of comments on this issue, from complete support for the proposed cord wood testing requirements to complete opposition to requiring cord wood testing at this time. We considered all comments and focused on those that discussed the data in detail. As discussed earlier in section IV, based on the data and comments submitted, we have determined that it is premature to require a cord wood-based Step 2 PM emission limit at this time (except for forced-air furnaces for which CSA B415.1–10 already specifies cord wood as the test fuel). Rather, we are basing the Step 2 PM emission limit on crib wood testing and including an alternative compliance option to meet an emission limit based on cord wood testing, to encourage manufacturers to certify with cord wood as soon as possible to provide consumers with better information for their actual inhome-use performance. There are some manufacturers that already achieve the cord wood emission level and we expect that many more manufacturers will take this option and submit data that will inform development of a required cord wood certification test in a future rulemaking. Based on the existence of a viable draft cord wood test method and the expectation at proposal that the ASTM test methods for cord wood would be complete soon after proposal and that significant testing of wood heaters retuned to perform well on cord wood would occur before promulgation of this final rule, the EPA proposed to require testing only with cord wood for compliance with Step 2 emissions limits. We still encourage manufacturers to design wood heaters that best represent actual in-home-use performance on cord wood. However, VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 the ASTM cord wood test methods have not been completed and only limited testing using the draft methods has occurred. For the cord wood alternative compliance option, we will consider approval of requested test methods on a case-by-case basis. We believe the current draft ASTM test methods are sufficient to be used, upon request, for the cord wood alternative compliance option until better test methods can be developed. We will also be receptive to other alternative test method requests that are adequately demonstrated, ideally according to the EPA Method 301 validation procedures. (Note that forced-air furnaces are tested according to the cord wood test method already specified in CSA B415.1–10. 2. Compliance for Individual Burn Rates Versus Weighted Averages We received a full range of comments on this issue, from complete support for the proposed Step 2 compliance for individual burn rates to using only the weighted averages similar to the 1988 NSPS. We considered all comments and focused on those that discussed the data in detail. As mentioned earlier in section IV, based on the data and comments submitted, we have determined that the final rule will require weighted averages for Step 2 in subpart AAA and individual burn rates for Step 2 in subpart QQQQ. For subpart AAA Step 2 emission limits, we proposed to require certification compliance at the lowest burn rate (Category 1) and the maximum burn rate (Category 4) rather than the weighted average of the four burn rates, which was required in the 1988 rule. Many comments on the proposal and the data in the NODA strongly supported the proposed compliance determinations per individual burn rates. Many other comments strongly opposed the proposal. Considering all of the comments and focusing on the available test data, especially the EPA wood stove certification test data by burn rate that we included in the July 1, 2014 NODA, we are requiring certification calculations based on the weighted average of the four burn rates for subpart AAA. As discussed earlier in section V.A, the data show that for weighted averages, 18 percent of noncatalytic stoves (that represent over 80 percent of the market) achieve 2.0 g/ hr. However, on an individual burn rate basis, only 6 percent (7 of 110 stoves) achieve 2.0 g/hr, a relatively small percentage of wood stoves manufactured today. This supports our decision that a Step 2 limit of 2.0 g/hr, based on a weighted average of the multiple burn rates, better represents PO 00000 Frm 00020 Fmt 4701 Sfmt 4700 BSER for wood stoves/heaters subject to revised subpart AAA, compared to a Step 2 limit based on individual burn rates. For subpart QQQQ, the final rule retains the proposed Step 1 g/hr emission cap for all burn rates (for hydronic heaters) and the Step 2 requirement for lb/mmBtu compliance at each burn rate (for both hydronic heaters and forced-air furnaces) given concerns about the sometimes very large emissions at individual burn rates. The emission limits reflect the data available. For a more detailed discussion of these comments and responses, see the RTC document in the docket for this rule. 3. National Technology Transfer and Advancement Act (NTTAA) We received a full range of comments on this issue, from complete support to adamant disagreement with our determinations under the NTTAA at proposal that some portions of some of the ASTM test methods were not applicable or impractical for this rule because they did not achieve the Agency’s mission, goals and objectives. (The NTTAA directs agencies to use voluntary consensus standards whenever applicable methods are available unless they are impractical.) As discussed in the proposal preamble in section VI.I, the rule incorporates some voluntary consensus standards (VCS) by reference, including some ASTM methods and CSA B415.1–10. We could not use some ASTM test methods and other VCS because they were not applicable. That is, the inapplicable VCS did not fully achieve the intent of this rule or the primary mission of the Agency and many tribes, states and local agencies to protect human health and the environment. Some comments claimed that the EPA cannot take portions of VCS but rather must only use the whole VCS. That position is inconsistent with the intent of the NTTAA goal for reducing duplication of effort. That is, using valuable portions of VCS helps reduce potential duplicative efforts. Some comments suggested that because the EPA unofficial participants (the EPA employees who were not ASTM members but participated in some of the calls) in certain ASTM test method development efforts did not submit official negatives on the standard, that somehow that meant that the EPA approved all of the details of the draft ASTM test methods. The EPA participants often expressed that the draft test methods were not fully applicable to the needs of the EPA and states; but since the draft test methods E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations may meet some of the immediate needs of the industry participants, the EPA did not want to stop the ASTM efforts to develop improved drafts. Further, the NTTAA guidance explicitly states that Agency participation does not indicate Agency approval or endorsement. 4. Real World, Cold Starts, Cycling, Moisture, Heat Demand Many comments indicated a critical need for test methods that reflect the ‘‘real world’’ with cord wood, cold starts, cycling, moisture, heat demand and shorter averaging periods. We strongly agree, and we will consider alternative cord wood test method requests on a case-by-case basis until we are convinced that improved test methods have been sufficiently demonstrated that they can be relied upon for regulatory purposes. Additionally, we expect that within the next few years we will receive enough ‘‘real world’’ cord wood test data for the EPA to establish revised certification requirements based on those test data. G. Health Effects and Benefits A more detailed summary of the comments is in the RTC document in the docket. mstockstill on DSK4VPTVN1PROD with RULES2 1. Additional Health Outcomes Several comments suggested that the EPA should expand its assessment of health benefits. The RIA includes all possible health impacts related to exposure to wood combustion-related PM2.5. Table 7–1 of the RIA on human health effects of ambient PM2.5 has an extensive list of the above mentioned health endpoints that were considered and monetized, including exacerbation of asthma among children. However, several were assessed qualitatively due to time and resource limitations. Table 7–2 of the RIA shows the results of the assessed health incidence reductions and related benefits from reduced PM2.5 exposure associated with the proposed option. 2. Additional Pollutants and Outcomes Comments suggested that the EPA should expand its assessment to include benefits of reductions in CO and VOC and certain non- human health-related benefits including: environmental degradation; accelerated depreciation of capital; haze; contribution to anthropogenic climate change; and harm to pets and livestock. The EPA understands that the benefits assessment in the RIA reflects only a subset of the benefits attributable to the health effects reductions associated with ambient fine particles. Limitations in data, time and resources prevented the VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 EPA from quantifying the impacts to, or monetizing the benefits from, several important benefits categories, including benefits associated with the potential exposure to ozone formation due to VOC emissions as a precursor, VOC emissions as a PM2.5 precursor, CO, as well as ecosystem effects, and visibility impairment due to the absence of air quality modeling data for these pollutants among others in this analysis. However, the EPA provided an extensive qualitative assessment of those benefits. The EPA realizes that the benefits presented are an underestimate of the overall benefits resulting from this rule and that these reductions will help with ozone and PM planning. 3. Additional Benefits of Reducing Greenhouse Gases Comments suggested that we expand the benefits analyses to include the benefits of reducing greenhouse gases. The EPA agrees that there will be added benefits from assessing impacts of emission reductions of carbon dioxide (CO2), methane and black carbon. While we know that these emissions will be reduced along with the reductions of PM emission and the increases in efficiency of the affected heaters, we do not have robust emissions test data to make quantitative benefits analysis on climate change at this time. One commenter referred to the interagency Social Cost of Carbon (SCC) estimates. The comment suggested that (1) EPA should use SCC to reflect the monetized CO2 impacts of the proposed rule in the RIA; and (2) EPA should use the SCC estimates published in 2010 instead of the updated SCC estimates published in 2013 because the updated estimates have not been subject to public comment. The SCC represents the monetized net damages of incremental changes in the amount of CO2 emissions in a given year. Given that CO2 impacts of the proposed rule were not analyzed, the SCC estimates were not used in the RIA. 4. Uncertainty of ‘‘Value per Statistical Life’’ Commenters stated that the EPA’s use of the Value per Statistical Life (VSL)— that is, the monetized value attributable to mortality reduction—is a source of uncertainty. While the Agency is updating its guidance by incorporating the most upto-date literature and recent recommendations from the Science Advisory Board Environmental Economics Advisory Committee (SAB– EEAC), it has determined that a single, peer-reviewed estimate applied PO 00000 Frm 00021 Fmt 4701 Sfmt 4700 13691 consistently best reflects the SAB–EEAC advice until updated guidance is available. Therefore, the EPA, after consulting with the Office of Management and Budget (OMB), has decided to use the value established in the 2000 Guidelines for all the EPA actions until a revised estimate can be fully vetted. The EPA will continue to look into approaches based on the best available science as appropriate. The EPA will continue to recommend the central estimate of $7.4 million ($2006), updated to the year of the analysis, be used in all benefits analyses that seek to quantify mortality risk reduction benefits regardless of the age, income, or other population characteristics of the affected population until revised guidance becomes available. This approach was vetted and endorsed by the Agency when the 2000 ‘‘Guidelines for Preparing Economic Analyses’’ were drafted. Although $7.4 million ($2006) remains EPA’s default guidance for valuing mortality risk changes, the Agency has considered and presented others and may well consider the commenter recommendation in future assessments. We agree that there is uncertainty. Recent analyses have estimated substantial increases in life expectancy and the number of life years gained due to improved PM2.5 air quality. For example, Hubbell (2006) estimated that reducing exposure to PM2.5 from air pollution regulations may result in an average gain of 15 years of life for those adults prematurely dying from PM2.5 exposure. In contrast, Pope et al. (2009) estimated changes in average life expectancy at birth over a 20-year period, suggesting that reducing exposure to air pollution may increase average life expectancy at birth by approximately 7 months, which was 15 percent of the overall increase in life expectancy at birth from 1980 through 2000. 5. Uncertainty in the EPA Analyses Regarding the Constant Benefits-per-Ton Simplifying Assumption, DoseResponse Relationship, and Benefits Transfer Approach Comments suggested that the relationship between pollution and human health is more complex than the EPA’s simplifying assumptions and thus more uncertain. The EPA’s methods for quantifying health benefits of emission reductions are based on the best available peerreviewed science and methods that have withstood scrutiny from the EPA’s independent Science Advisory Board (SAB), the National Academy of E:\FR\FM\16MRR2.SGM 16MRR2 13692 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations Sciences (NRC, 2002), and continuous interagency review. The RIA references a peer-reviewed manuscript and technical support document (TSD) that each describe the methods EPA employed to quantify the per-ton benefit of reducing fine particle levels from various sources. The air quality modeling attributed fine particle levels to residential wood heaters, holding all other sectors constant— giving us greater confidence that we have correctly characterized the air quality and health impacts attributable to this sector. With respect to the incidence of benefits among populations living in locations already attaining the primary NAAQS, the EPA acknowledges that primary NAAQS are set at a level deemed by the EPA Administrator to be protective of public health with an adequate margin of safety. At the same time, primary NAAQS are not set at a level of zero risk and there is no known threshold below which PM2.5 does not cause adverse health effects. Thus, the EPA recognizes that reducing the emissions level in those areas could still have health benefits. Additional detail of our responses is included in the final RIA. mstockstill on DSK4VPTVN1PROD with RULES2 VI. Summary of Environmental, Cost, Economic, and Non-Air Health and Energy Impacts The EPA estimates the total annualized average nationwide costs associated with this rule would be $45.7 million ($2013) over the timeframe of 2015 through 2020. The economic impacts for industries affected by this rule over this same period, estimated as a percent of annual compliance cost to sales, range from 1.1 percent for manufacture of pellet stove models to 17.1 percent for manufacture of hydronic heater models. These impacts do not presume any pass-through of impacts to consumers. With passthrough to consumers, these impact estimates to manufacturers will decline proportionate to the degree of passthrough. A. What are the air quality impacts? In section IV of the preamble to the proposed rule, we described the procedure we used to determine the air quality impacts on the industries affected by this rule. Following proposal, we revised the standards for room heaters and central heaters based on public comments. Table 6 is a summary of the revised estimated annual average emissions reductions over years 2015 through 2020 resulting from implementing the final NSPS compared to baseline conditions (for the VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 years analyzed in the final RIA). As in the proposal, we developed emission factors for each appliance type and then applied those emission factors to shipment data for each of the appliance types subject to the final NSPS.16 We developed the emission factors using the EPA Residential Wood Combustion (RWC) emission estimation tool,17 which is a Microsoft Access database that compiles nationwide RWC emissions using county-level, processspecific data and calculations. The compilation of such data is a large, important, continually improving effort by the EPA and the states to ensure that we and the states have access to the best information available. For the final rule, we used the updated version of the tool. The updated tool includes the results of a peer-reviewed emission testing study of hydronic heaters conducted by the EPA Office of Research and Development and the New York State Energy Research and Development Agency. (The study was added to the docket prior to proposal but the tool was not updated until after proposal.) The results of that study show much higher emissions for hydronic heaters at baseline than we estimated at proposal. We have used the updated emission factors because they are based on the best available scientific information. We summed the estimated nationwide number of appliances and the estimated total tons of wood burned for each of the relevant product categories in the inventory and then made some adjustments/assumptions to the baseline RWC inventory to reflect emission characteristics specific to new units. As described below, to avoid any potential for overstating baseline emissions, we went a step further and assumed that all new shipments will meet the current State of Washington Department of Ecology limits, which are approximately 40 percent less than the 1988 NSPS. Single burn rate stoves are not included in the RWC database as separate identifiable units. For our analysis, we used the same baseline emission factor as freestanding noncertified wood stoves. We used the average tons burned per appliance factor as representative of these stoves as well. After calculating a baseline average emission rate/appliance (or ‘‘emission inventory category’’), we multiplied the total tons of wood burned for the 16 Memo to USEPA from EC/R, Inc. Estimated Emissions from Wood Heaters. January 2015. 17 Emission factors are based on EPA’s Residential Wood Combustion Tool version 4.1 with updates from the 2012 EPA report (Gullett et al.

PO 00000 Frm 00022 Fmt 4701 Sfmt 4700 appliance by the RWC emission factor (adjusted as appropriate) to calculate the total tons of PM2.5 emissions. We divided this value by the number of appliances in the category to calculate the baseline average PM2.5 emissions per individual appliance. The next step was to develop emission factors representing the final NSPS. The timing of the NSPS emission limits used in this analysis matches the phased-in compliance dates. For the subpart AAA analysis, we used HPBA data from their 2010 analysis that indicated that at least 90 percent (130 out of 145 catalytic, noncatalytic and pellet stoves combined) already meet the Step 1 PM emission limit. Manufacturers are expected to focus on existing models that already meet the Washington State DOE limits in order to comply with the Step 1 PM emission limit. Furthermore, certification data 18 indicate that 26 percent of non-catalytic and catalytic stoves combined and 70 percent of pellet stoves already meet the Step 2 PM emission limit. For our analysis, we used 26 percent of adjustable burn rate stoves and 70 percent of pellet stoves for the percentages that can already meet the Step 2 PM emission limit without intensive R&D efforts. Although previously unregulated and a less developed technology than adjustable burn rate stoves, single burn rate stove designs have been undergoing R&D in anticipation of the proposed NSPS and cleaner designs are in progress. For the subpart QQQQ analysis for hydronic heaters, we note that the Step 1 PM emission limit is the EPA ‘‘Phase 2’’ voluntary program lb/mmBtu weighted average emission limit is already met by 50 hydronic heater models built by U.S. manufacturers participating in the voluntary program. We also note that 19 additional qualification tests have been recently submitted to EPA and, if valid, all 19 will be added as Phase 2 qualified models and Step 1 NSPS certified models. The NSPS Step 2 PM emission limit is already met by 9 hydronic heater models built by U.S. manufacturers participating in the voluntary program, as well as over 100 European models per test method EN 303–05 and over 20 pellet boilers (U.S. and European) that have been qualified in the RHNY program. Data indicate that at least 18 percent of current hydronic heater model designs can meet the Step 2 emission limit without intensive R&D efforts. 18 Memo to USEPA from EC/R, Inc. Derivation of wood heater model percentages meeting Step 2 standards. November 2014. E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations For the subpart QQQQ analysis for forced-air furnaces, we note that the Step 1 PM emission limit is based on test data from certifications under the Canadian standard B415.1–10 (circa 2010) and conversations with industry regarding cleaner forced-air furnace models currently being tested in R&D. As discussed earlier in this preamble, forced-air furnace designs able to meet the Step 2 limit are based on technology transferred from hydronic heater designs and/or wood stove designs. Next we used data in the Frost & Sullivan Market (F&S) report 19 on 2008 shipments by product category, and F&S revenue forecasts which incorporated the weak economy in years 2009 and 2010, to calculate the reduced number of shipments in years 2009 and 2010. Forced-air furnaces were outside the scope of the F&S report. Instead, we used manufacturer estimates of total industry sales in 2008 and applied the F&S market factors to estimate shipments through 2010. The F&S wood stove numbers included both certified and non-certified stoves, so we estimated numbers of non-certified stove shipments out of the total reported wood stove category (i.e., 40,000 single burn rate stoves shipped in 2008). These shipments were deleted from the total wood stove category shipments. We expanded the 2008 single burn rate estimate using the F&S factors. For years 2011 through 2029, estimated shipments are generally based on a forecasted revenue growth rate of 2.0 percent, in keeping with the average annual growth in real U.S. GDP predicted by the Conference Board.20 Historically wood heater shipments have most closely corresponded to GDP, housing starts, and price of wood relative to natural gas. The overall trend in the projection is reasonable in the absence of additional specific shipment projections. We did not change the relative percentages of one type of residential wood heater versus other types of residential wood heaters over this time period. The only exceptions to the use of a 2.0 percent U.S. GDP-based growth rate are for years 2012 and 2018, in which we used industry estimates for hydronic heater and wood stove shipments, respectively. For year 2012, an HPBA consultant estimated there were 13,100 baseline hydronic heater sales.21 For year 2018, the same HPBA consultant projected there to be 100,000 wood stove sales.22 We adjusted our estimated shipment data accordingly. Our cost effectiveness analysis (CE) is based on industry data that show that a given model design will often be sold for approximately 10 years before being redesigned (a 10-year ‘‘model design lifespan’’) and that each individual stove will be used for 20 years before it is replaced in a residence (a 20-year 13693 ‘‘use/emitting appliance lifespan’’). These time periods were used to best characterize the actual model design and use lifespans. For proposal, we used a 20-year model design lifespan because many models developed for the 1988 NSPS are still being sold (after 25 years), with many ‘‘new’’ models retaining the same internal working parts with merely exterior cosmetic changes. In response to comments on the proposed rule,23 however, in which some industry representatives commented that a shorter model lifespan is more typical, and provided data for models for several manufacturers, we reduced the model design lifespan to 10 years for this analysis. Regarding the emitting lifespan of the appliance, most wood heaters in consumer homes emit for at least 20 years and often much longer. Therefore, our CE analysis tracks shipments through year 2029 (using a 10-year design life for a model meeting the Step 2 emission limit in year 2020) and emissions through year 2048 (using a 20-year emitting life for an appliance shipped in year 2029). Table 6 is a summary of the average emissions reductions over years 2015 through 2020 resulting from implementing the NSPS compared to baseline conditions (for the years analyzed in the RIA).

E:\FR\FM\16MRR2.SGM 16MRR2 13694 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations B. What are the benefits? Emission reductions associated with the requirements of this rule will generate substantial health benefits by reducing emissions of PM2.5, HAPs, as well as criteria pollutants and their precursors, including CO and VOC. VOC are precursors to PM2.5 and ozone. For this rule, we were only able to quantify the monetized health cobenefits associated with reduced exposure from directly emitted PM2.5. Our benefits reflect the average of annual PM2.5 emission reductions occurring between 2015 and 2020 (inclusive). We estimate the monetized PM2.5-related health benefits of the residential wood heaters NSPS in the 2015–2020 timeframe to be $3.4 billion to $7.6 billion (2013 dollars) at a 3percent discount rate and $3.1 billion to $6.9 billion (2013 dollars) at a 7-percent discount rate. (These estimates are greater than the estimates at proposal because the emission reduction estimates are greater, as discussed in section VI.A of this preamble and the RIA.) Using alternate relationships between PM2.5 and premature mortality supplied by experts, higher and lower benefits estimates are plausible, but most of the expert-based estimates fall between these two estimates.25 A summary of the emission reduction and monetized benefits estimates for this rule at discount rates of 3 percent and 7 percent is in Table 7 of this preamble. TABLE 7—SUMMARY OF MONETIZED PM2.5-RELATED HEALTH BENEFITS FOR PROPOSED RESIDENTIAL WOOD HEATERS NSPS IN 2015–2020 TIMEFRAME [millions of 2013 dollars] a b c Estimated emission reductions (tpy) Pollutant Directly emitted PM2.5 ......................................................................................

The total monetized benefits reflect the human health benefits associated with reducing exposure to PM2.5 through reductions of PM2.5 precursors, such as NOX, and directly emitted PM2.5. It is important to note that the monetized benefits do not include reduced health effects from exposure to HAP, direct exposure to NO2, exposure to ozone, VOC, ecosystem effects, effects from black carbon or visibility impairment. b PM benefits are shown as a range from Krewski, et al. (2009) to Lepeule, et al. (2012). c These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effects estimates by particle type. mstockstill on DSK4VPTVN1PROD with RULES2 These benefit estimates represent the monetized human health benefits for populations exposed to less PM2.5 from emission limits established to reduce air pollutants in order to meet this rule. Due to analytical limitations, it was not possible to conduct air quality modeling for this rule. Instead, we used a ‘‘benefit-per-ton’’ approach to estimate the benefits of this rulemaking. To create the benefit-per-ton estimates, this approach uses a model to convert emissions of PM2.5 precursors into changes in ambient PM2.5 levels and another model to estimate the changes in human health associated with that change in air quality, which are then divided by the emissions in specific sectors. These benefit-per-ton estimates were derived using the approach published in Fann, et al., (2012),26 but they have since been updated to reflect these studies and population data in the 2012 p.m. NAAQS RIA.27 Specifically, we multiplied the benefit-per-ton estimates from the ‘‘Residential Wood Heaters’’ category by the corresponding emission reductions.28 All nationalaverage benefit-per-ton estimates reflect the geographic distribution of the modeled air quality. The air quality modeling may not reflect the local variability in population density, meteorology, exposure, baseline health incidence rates, or other local factors for any specific location. More information regarding the derivation of the benefitper-ton estimates for this category is available in the technical support document, which is referenced in footnote 26 and is available in the docket. These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effects estimates by particle type. Even though we assume that all fine particles have equivalent health effects, the benefitper-ton estimates vary between precursors depending on the location and magnitude of their impact on PM2.5 levels, which drive population exposure. It is important to note that the magnitude of the PM2.5 benefits is largely driven by the concentration response function for premature mortality. We cite two key empirical studies, one based on the American Cancer Society cohort study 29 and the extended Six Cities cohort study.30 In the RIA for this rule, which is available in the docket, we also include benefits estimates derived from expert judgments (Roman et al., 2008) as a characterization of uncertainty 24 Memo to USEPA from EC/R, Inc.

Considering a substantial body of published scientific literature, reflecting thousands of epidemiology, toxicology, and clinical studies, the EPA’s Integrated Science Assessment for Particulate Matter 31 documents the association between elevated PM2.5 concentrations and adverse health effects, including increased premature mortality. This assessment, which was reviewed twice by the EPA’s independent Clean Air Scientific Advisory Committee, concluded that the scientific literature consistently finds that a no-threshold model most adequately portrays the PM-mortality concentration-response relationship. Therefore, in this analysis, the EPA assumes that the health impact function for fine particles is without a threshold. In general, we are more confident in the magnitude of the risks we estimate from simulated PM2.5 concentrations that coincide with the bulk of the observed PM concentrations in the epidemiological studies that are used to estimate the benefits. Likewise, we are less confident in the risk we estimate from simulated PM2.5 concentrations that fall below the bulk of the observed data in these studies. Concentration benchmark analyses [e.g., lowest measured level (LML) or one standard deviation below the mean of the air quality data in the study] allow readers to determine the portion of population exposed to annual mean PM2.5 levels at or above different concentrations, which provides some insight into the level of uncertainty in the estimated PM2.5 mortality benefits. There are uncertainties inherent in identifying any particular point at which our confidence in reported associations becomes appreciably less, and the scientific evidence provides no clear dividing line. However, the EPA does not view these concentration benchmarks as a concentration threshold below which we would not quantify health benefits of air quality improvements. For this analysis, policy-specific air quality data are not available. Thus, we are unable to estimate the percentage of premature mortality associated with this specific rule’s emission reductions at each PM2.5 level. As a surrogate measure of mortality impacts, we provide the percentage of the population exposed at each PM2.5 level using the source 31 U.S. Environmental Protection Agency (U.S. EPA). 2009.

Using the Krewski, et al., (2009) study, 93 percent of the population is exposed to annual mean PM2.5 levels at or above the LML of 5.8 mg/m3. Using the Lepeule, et al., (2012) study, 67 percent of the population is exposed above the LML of 8 mg/m3. It is important to note that baseline exposure is only one parameter in the health impact function, along with baseline incidence rates, population, and change in air quality. Therefore, caution is warranted when interpreting the LML assessment for this rule. Every benefit analysis examining the potential effects of a change in environmental protection requirements is limited, to some extent, by data gaps, model capabilities (such as geographic coverage) and uncertainties in the underlying scientific and economic studies used to configure the benefit and cost models. Despite these uncertainties, the benefit analysis for this rule provides a reasonable indication of the expected health benefits of the rulemaking under a set of reasonable estimations. One should note that the monetized benefits estimates provided above do not include benefits from several important benefit categories, including exposure to HAP, VOC and ozone exposure, as well as ecosystem effects, visibility impairment and greenhouse gas impacts. Although we do not have sufficient information or modeling available to provide monetized estimates for these benefits in this rule, we include a qualitative assessment of these unquantified benefits in the RIA 32 for this final rule. For more information on the benefits analysis, please refer to the RIA for this rule, which is available in the docket. C. What are the cost impacts? In analyzing the potential cost impacts of the NSPS, we considered two types of impacts. The first was the impact to the manufacturer to comply with the proposed standards. The second was the increase in price of the affected unit. In both of these cases, we considered the same input variables: Research and development (R&D) cost to develop and certify complying model lines, certification costs (where these are separate from R&D), reporting and recordkeeping costs, numbers of shipments of each appliance category (modified, from Frost & Sullivan report), number of manufacturers, and number of models per manufacturer. This 32 RIA for the Final Residential Wood Heaters NSPS. PO 00000 Frm 00025 Fmt 4701 Sfmt 4700 13695 section of the preamble contains a summary of these costs. For more detailed information, see the manufacturer cost impact memo 33 and unit cost memo 34 in the docket. Unless otherwise specified, all costs are in 2013 dollars. As discussed in detail in section IV.C, we reviewed information provided by HPBA and manufacturers. Based on this information, we estimated 35 average costs to develop a new model line. The estimates of the cost of R&D are crucial to our estimates of overall costs and economic impacts and greatly influence our decisions on BSER and implementation lead times. We annualized the R&D costs over 6 years, applied the NSPS implementation assumptions, and estimated the average manufacturing cost per model line per manufacturer. The estimate of the number of model types was derived from information provided by HPBA, individual manufacturers, and Internet searches of product offerings. For numbers of manufacturers, we started with HPBA data and modified the dataset based on Internet searches of manufacturers of the major appliance types. Table 8 is a summary of the nationwide average annual NSPS-related cost increases to manufacturers. The average annual cost increases are presented over the 2015 to 2020 period consistent with the years analyzed in the RIA,36 but were also analyzed over the 2015 to 2029 period. The 2015 to 2029 period encompasses the 2015 NSPS compliance year through the life span of models designed to meet the NSPS, as explained further below and in our background analyses.37 TABLE 8—SUMMARY OF NATIONWIDE AVERAGE ANNUAL COST INCREASES [2013$] Appliance type 2015–2020 Period Wood Heaters ...........................

In developing this calculation, we included the concept that the R&D costs per model line are recovered in the sales price of future models, which means that the more units that are sold, the lower the incremental cost per unit. For our unit cost analysis, we used a flat rate in shipments—that is, future shipments over the 6-year model development period would be equal to the shipments estimated in the first year of the 6-year model development period (2015). The flat rate was used because we had no basis for concluding that sales of a given model line would increase or decrease over time due to market competition with other wood heaters or non-wood heaters, changes in consumer demand, changes in the relative price for that model compared to other models or any other factors. Where there are additional manufacturing costs as discussed above, we added these to the unit cost number. Table 9 shows the change in cost to develop and manufacture a stove from baseline (before the NSPS revisions) to after the NSPS revisions are implemented. The economic impacts of these costs are discussed in section C, ‘‘What are the economic impacts?’’ More information on both the costs and economic impacts is available in the RIA.

What are the economic impacts? The economic impacts of the rule are estimated using industry-level estimates of annualized compliance cost to value of shipments (receipts) for affected industries. In this case, cost-to-receipts ratios approximate the maximum price increase needed for a producer to fully 38 Memo to USEPA from EC/R, Inc.

These industry level cost-to-receipts ratios can be interpreted as an average impact on potentially affected firms in these industries.

In estimating the net benefits of regulation, the appropriate cost measure is ‘‘social costs.’’ Social costs represent the welfare costs of the rule to society and fully represent the cost impacts regardless of whether they are ultimately borne by manufacturers or consumers. Social costs are best approximated by the compliance costs estimated for this rule. Thus, the annualized social costs are best estimated to be $45.7 million, based on the estimate of costs to manufacturers and assuming no cost pass-through to consumers. Several comments noted that these potential price increases can often be offset by the homeowner in one or two heating seasons by the reduced cost of fuel due to the increased heating efficiencies. More information on how these social costs are estimated can be found in Chapter 5 of the RIA. mstockstill on DSK4VPTVN1PROD with RULES2 E. What are the non-air quality health and energy impacts? These NSPS are anticipated to have no impacts or only negligible impacts on water quality or quantity, waste disposal, radiation or noise. To the extent new NSPS models are more efficient, that would lead to reduced wood consumption, thereby saving timber and preserving woodlands and vegetation for aesthetics, erosion control, carbon sequestration, and ecological needs. It is difficult to determine the precise energy impacts that might result from this rule. On the one hand, to the extent that the NSPS wood-fueled appliance is more efficient, energy outputs per mass of wood fuel consumed will rise. However, wood-fueled appliances compete with other biomass forms as well as more traditional oil, electricity, and natural gas. Robust data are not available for us to be able to determine the potential for consumers to choose other types of fuels and their associated appliances if the consumer costs of wood-fueled appliances increase and at what level that increase would drive consumer choice. Similarly, robust data are not available for us to determine the degree to which better information on the energy efficiency of the NSPS appliances will encourage consumers to choose new wood-fueled appliances over other new appliances.

Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is an economically significant regulatory action that was submitted to the Office of Management and Budget (OMB) for review. Any changes made in response to OMB recommendations have been documented in the docket. The EPA prepared an analysis of the potential costs and benefits associated with this action. This analysis, ‘‘Regulatory Impact Analysis (RIA) for Residential Wood Heaters NSPS Revision, Final Report’’ (EPA–452/R–15–001), is available in the docket. A summary of the monetized benefits and net benefits for the final rule at discount rates of 3 percent and 7 percent is in Table 1 of this preamble, and a more detailed discussion of the benefits is found in section IV.B of this preamble. For more information on the benefits analysis, please refer to the RIA for this rulemaking, which is available in the docket. For more information on the cost analysis, please refer to the RIA or cost memoranda prepared for this rulemaking, all of which is available in the docket. B. Paperwork Reduction Act (PRA) The information collection requirements in the rule have been submitted for approval to OMB under the PRA. The Information Collection Request (ICR) documents that the EPA prepared for each subpart have been assigned the EPA ICR number 1176.12 for subpart AAA and ICR number 2442.02 for subpart QQQQ. You can find a copy of the ICR documents in the docket for this rule, and they are briefly summarized here. The new information collection requirements are not enforceable until OMB approves them. This final rule will require manufacturers of new residential wood heating devices 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 quality control plan approved by an independent certifying body. 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 quality assurance program inspections PO 00000 Frm 00027 Fmt 4701 Sfmt 4700 13697 and emissions test data, and seal and store the tested appliance. Consistent with the current ICR for subpart AAA, we have included costs to manufacture and 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 NSPS allows (voluntary) use of EPA temporary labels for the cleanest heaters in order to provide consumers the ability to select wood heaters that meet or exceed the Step 2 standards prior to the 2020 compliance date. This voluntary temporary label option ends upon the 2020 compliance date. Furthermore, the amended NSPS also allows (voluntary) use of temporary EPA labels to indicate wood heaters that meet Step 2 based on cord wood instead of crib wood, allowing consumers to select heaters better tuned to in-home performance. The cost of the voluntary temporary labels are not included because they are not required. Test laboratories that want to conduct NSPS certification testing will need to apply for approval, conduct proficiency testing and report the results of all such testing. The approved laboratories must maintain records of all certification tests, proficiency tests and compliance audit test data. The required notifications are used to inform the agency when a new model line is expected to be tested. The EPA and states may then observe the testing, if desired. Emissions test reports are needed as these are the agency’s record of a model line’s initial capability to comply with the emission limit, and serve as a record of the operating conditions under which compliance was achieved. All information submitted to the EPA for which a claim of confidentiality is made (e.g., design drawings) 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. 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 prioritizing inspections and is of sufficient quality to be used as evidence in court. We have reviewed all the current requirements and have removed the portions of the recordkeeping that are not necessary. The EPA considered how to minimize the potential ICR burdens and has incorporated several features that make a major paperwork reduction impact.

The revised subpart AAA itself ‘‘deems’’ automatic EPA certification of heaters that have EPA certifications under the 1988 NSPS that show that they would meet the Step 1 emission limits until Step 2. That is, no additional certification is required until Step 2. Also, the new subpart QQQQ deems automatic EPA NSPS Step 1 certification for hydronic heaters with valid EPA Phase 2 qualifications under the EPA Hydronic Heater Partnership Agreement of October 12, 2011 or hydronic heaters or forced-air furnaces certified by the NYSDEC that show compliance with the Step 1 emission levels. That is, no additional certification is required until Step 2. Also, residential pellet hydronic heaters/boilers that have been qualified under the Renewable Heat New York (RHNY) program will be automatically deemed EPA certified to meet the NSPS Step 1 and no additional certification is required until Step 2 provided that they comply with the RHNY requirements for installation and operation with adequate thermal storage. Respondents/affected entities: Manufacturers of new residential wood heaters and laboratories that conduct or plan to conduct wood heater certification tests. Respondent’s obligation to respond: Mandatory under section 111 of the CAA. Estimated number of respondents: 72 respondents under subpart AAA (66 manufacturers and 6 testing laboratories); 41 respondents under subpart QQQQ (37 manufacturers and 4 testing laboratories). Frequency of responses: once per model line, annually, biennially, variable and/or infrequent. Total estimated burden: 2,947 labor hours (per year) under subpart AAA; 2,337 labor hours (per year) under subpart QQQQ. Burden is defined at 5 CFR 1320.3(b). Total estimated cost: $1,716,990 (per year) under subpart AAA, includes $1,466,440 annualized capital and operation & maintenance costs; $3,383,100 (per year) under subpart QQQQ, includes $3,191,200 annualized capital and operation & maintenance costs. 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 the EPA’s regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves this ICR, the agency will VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 announce that approval in the Federal Register and publish a technical amendment to 40 CFR part 9 to display the OMB control number for the approved information collection activities contained in this final rule. C. Regulatory Flexibility Act (RFA) Pursuant to sections 603 and 609(b) of the RFA, the EPA prepared an initial regulatory flexibility analysis (IRFA) for the proposed rule and convened a Small Business Advocacy Review (SBAR) Panel to obtain advice and recommendations from small entity representatives that potentially would be subject to the rule’s requirements. Summaries of the IRFA and Panel recommendations are presented in the proposed rule at 79 FR 6329. As required by section 604 of the RFA, the EPA prepared a final regulatory flexibility analysis (FRFA) for this action. The FRFA addresses the issues raised by public comments on the IRFA for the proposed rule. The complete FRFA is available for review in the docket and is summarized here. • Reason Why Action Is Being Considered. As discussed earlier in this preamble, this final rule was developed following CAA section 111(b)(1)(B) review of the existing residential wood heater NSPS, and because emissions from residential wood heaters can be a significant source of air pollution, and thus adverse health effects, in some areas. • Statement of Objectives and Legal Basis of Rule. As discussed earlier in this preamble, the EPA is amending Standards of Performance for New Residential Wood Heaters and adding one new subpart, Standards of Performance for New Residential Hydronic Heaters and Forced-Air Furnaces. This final rule achieves several objectives, including applying updated emission limits that reflect BSER; improving coverage of the broad suite of residential wood heaters; improving the test methods; and streamlining the certification process. This final rule does not include any requirements on heaters solely fired by coal, gas or oil. This final rule does not establish new emissions limits for existing heaters. This rule was developed under the authority of CAA section 111. • Response to Any Comments to the Proposed Rule Filed by the Chief Counsel for Advocacy of the SBA. The SBA’s Chief Counsel for Advocacy did not file any comments to the proposed rule. • Description and Estimate of the Number of Small Entities. As discussed earlier in this preamble, small entities PO 00000 Frm 00028 Fmt 4701 Sfmt 4700 that the EPA anticipates being affected by this rule will include almost all manufacturers of residential wood heaters. We estimate that roughly 250– 300 U.S. companies manufacture residential wood heaters. Approximately 90 percent of these manufacturers meet the SBA smallentity definition of having fewer than 500 employees. • Description of reporting, recordkeeping and other compliance requirements. The reporting and recordkeeping requirements are described in the section immediately above (B. Paperwork Reduction Act). As discussed there, the information collection requirements (ICR), including reporting and recordkeeping, in this rule have been submitted for approval to OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. For subpart AAA, we estimated the potential annual burden averaged over the first 3 years of the ICR to be a total of 2,947 labor hours per year at a total labor cost of $250,551 per year and an average annual labor burden per response of 12 hours. For subpart QQQQ, we estimated 2,337 labor hours per year at a total labor cost of $191,904 per year and an average annual labor burden per response of 12 hours. • Description of other compliance requirements. As described earlier in this preamble, this rule will apply updated emission limits that reflect the current best systems of emission reduction (BSER) and improve the coverage of the expanded variety of types of residential wood heaters. We estimate the NSPS’s total annualized average nationwide costs will be $45.7 million (2013$) over the 2015 through 2020 period. The economic impacts for industries affected by this rule over this same period range from 1.1 percent for manufacture of pellet stove models to as much as 17.1 percent compliance costto-sales estimate for manufacture of hydronic heater models. These impacts do not presume any pass-through of impacts to consumers. With passthrough to consumers, these impact estimates to manufacturers will decline proportionate to the degree of passthrough. We estimate that small entities will have annualized costs of greater than 1 percent of their sales in all affected industries, and NAICS 442299 with receipts less than $10 million. Those establishments in NAICS 332510, 333414 and 423720 with cost-to-receipt ratios higher than 1 percent account for 90 percent of small entities affected in these industries. Establishments in NAICS 442299 with cost-to-receipt ratios higher than 1 percent account for E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations 99 percent of small entities affected in these industries. • Relevant federal rules that may overlap or conflict with this rule. There are no other relevant federal rules. • Significant alternatives. The significant alternatives to this rule, especially those that might minimize potential impacts on small entities, are presented in the remainder of this section. As required by section 609(b) of the RFA, as amended by the Small Business Regulatory Enforcement Fairness Act (SBREFA), the EPA also convened a Small Business Advocacy Review Panel (Panel) to obtain advice and recommendations of representatives of the small entities that potentially would be subject to the rule’s requirements. The following paragraphs describe the process, the type of small entity representatives, the outreach efforts and the Panel members. Well before beginning the formal SBREFA process, the EPA actively engaged in outreach with HPBA, MHA and PFI and many of their member companies to discuss the rule under development and to provide these contacts with an early opportunity to ask questions and discuss their concerns.42 The EPA provided each small business with general information on the SBREFA process and background information on the NSPS rulemaking process and current schedule. Based on consultations with the SBA, and resulting from solicited selfnominations, we prepared a list of 30 potential Small Entity Representatives (SERs), from residential wood heating appliance manufacturers (wood heaters, pellet heaters/stoves, hydronic heaters, forced-air furnaces and masonry heaters), other wood-burning appliance manufacturers (fireplaces, cook stoves), equipment suppliers, chimney sweeps, test laboratories, masons and trade associations. Once the official pre-Panel process began and potential SERs were identified, the EPA held an outreach meeting with the potential SERs and invited representatives from the Office of Advocacy of the Small Business Administration (OA/SBA) and the Office of Information and Regulatory Affairs within the Office of Management and Budget (OIRA/OMB) on June 29, 2010, to solicit their feedback on the upcoming proposed rulemaking. Representatives from 26 of the 30 42 Also, as noted in the proposal preamble in the discussion of development of the proposed hydronic heater emission limits, the EPA worked with the hydronic heater industry in 2006 to develop a voluntary partnership program to encourage manufacture of cleaner models, www.epa.gov/burnwise/participation. VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 companies and organizations that we selected as potential SERs for this SBREFA process participated in the meeting (in person and by phone). At that meeting, the EPA solicited written comments from the potential SERs, which were later summarized and shared with the Panel as part of the convening document. The SBAR Panel convened on August 4, 2010. The Panel consisted of representatives of the EPA, OA/SBA and OIRA/OMB. The Panel held a formal outreach meeting/teleconference with the SERs on August 25, 2010. To help the SERs prepare for this meeting, on August 11, 2010, the Panel sent a list of questions, preliminary cost information and other materials to each of the SERs via email. Additional materials were emailed to the SERs on August 19, 2010. The Panel provided the opportunity for questions and comment during the meeting on various aspects of the proposal being developed, including the expanded scope of the rule, changes to the current requirements under consideration, preliminary cost information and follow up from the June 29, 2010, meeting on the SERs’ ideas for regulatory flexibility. During the August 25 meeting, SERs voiced general support for the planned proposed rule and shared specific concerns with the Panel members. As a result of this meeting, the EPA received many useful verbal comments, and the EPA received many helpful written comments by September 10, 2010. Consistent with the RFA/SBREFA requirements, the Panel evaluated the assembled materials and small-entity comments on issues related to elements of the Interim Regulatory Flexibility Analysis. A copy of the Panel final full report is included in the docket for this rule. We have attempted to follow the Panel’s recommendations to the degree we can while also ensuring that the options are practicable, enforceable, environmentally sound and consistent with the CAA. For those recommendations not adopted by the EPA, we included an explanation at proposal for why we rejected them. Further information about the panel is provided in the FRFA and the SBREFA Panel final report that are included in the docket for this rule. In addition, the EPA is preparing a Small Entity Compliance Guide to help small entities comply with this rule. Small entities can obtain of a copy of this guide at https://www.epa.gov/rfa/ compliance-guides.html or https:// www2.epa.gov/residential-wood-heaters. We expect the Small Entity Compliance Guide to be available by April 2015. PO 00000 Frm 00029 Fmt 4701 Sfmt 4700 13699 D. Unfunded Mandates Reform Act (UMRA) This action does not contain any unfunded mandates of $100 million or more as described in UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. This action imposes no enforceable duty on any state, local or tribal governments. The nationwide annualized average compliance cost of this rule for directly affected appliances is $45.7 million/yr in the 2015–2020 timeframe (2013$). Therefore, this final rule is not be subject to the requirements of sections 202 or 205 of the UMRA. This final rule is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. The rule does not apply to such governments and will impose no obligations upon them. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. The rule will not impose any requirements on state and local governments. Thus, Executive Order 13132 does not apply to this final rule. Although section 6 of Executive Order 13132 does not apply to this final action, the EPA did consult with representatives of state and local governments in developing this action. In the spirit of Executive Order 13132 and consistent with the EPA policy to promote communications between the EPA and state and local governments, the EPA solicited comment on the proposed rule from state and local officials. We have responded to their significant comments in this preamble and in the RTC document. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications as specified in Executive Order 13175. This rule will not impose any requirements on tribal governments. Thus, Executive Order 13175 does not apply to this action. Consistent with the EPA Policy on Consultation and Coordination with Indian Tribes, the EPA consulted with tribal officials during the development of this action. A summary of that consultation is provided here. During E:\FR\FM\16MRR2.SGM 16MRR2 13700 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations the development of the proposed rulemaking, the EPA conducted outreach with numerous tribal representatives to provide opportunities for input prior to development of the proposed rule. We provided information at the July 2010, National Tribal Forum/ National Tribal Air Association (NTAA) meeting in Albuquerque, New Mexico, and the November 2010, EPA Region 10 Tribal Leaders Summit in Juneau, Alaska. We also presented information on this proposed rulemaking in the April 2010, issue of Tribal Air News and during the EPA/NTAA tribal workgroup conference calls (April 2010, July 2010, August 2010, and May 2013). Specifically, we received input from the EPA/NTAA tribal workgroup members on culturally relevant exclusions from the proposed standards. We agreed with their input, clarified that we do not intend to regulate ceremonial fires, and added a definition to the rule to exclude traditional Native American bake ovens. On February 18, 2011, the EPA mailed letters to about 600 elected tribal leaders in the U.S. offering an opportunity for consultation on this proposal. We received requests from six tribes. These tribes agreed to discuss this proposal with us in a conference call held on March 22, 2011. The tribes were very supportive of this proposal and provided some helpful clarifications of definitions (e.g., Native American bake ovens) that we have incorporated in this proposal. We continued to provide updates on the rule on the EPA/NTAA conference calls and to offer opportunities to tribal leaders for consultation. On January 30, 2014, and September 25, 2014, we presented updates for tribes at the monthly EPA/ NTAA conference calls. The air quality and public health benefits to be achieved by this rule will benefit tribes. The emissions occur in neighborhoods and affect people in their homes. To the extent that populations are particularly sensitive to asthma, this rule will help. mstockstill on DSK4VPTVN1PROD with RULES2 G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks This action is not subject to Executive Order 13045 because the EPA does not believe the environmental health risks or safety risks addressed by this action present a disproportionate risk to children. This action’s health and risk assessments are contained in the RIA as well as the report ‘‘Analysis of Exposure to Residential Wood Combustion Emissions for Different Socio-Economic VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 Groups’’ 43 which shows that on a nationwide basis, cancer risks due to residential wood smoke emissions among disadvantaged population groups generally are lower than the risks for the general population due to residential wood smoke emissions. One of the demographic variables examined for this report was that of people 18 years and younger. The full report is available in the docket. This final rule is expected to reduce environmental impacts for everyone, including children. This action promulgates emissions limits at the levels based on BSER, as required by the CAA. Based on our analysis, we believe this rule will not have a disproportionate impact on children, and, in fact, will result in improvements to children’s health. These emissions happen in neighborhoods and affect people in their homes. To the extent that children are particularly sensitive to asthma, this rule will help. H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This action is not a ‘‘significant energy action’’ because it is not likely to have a significant adverse effect on the supply, distribution or use of energy. Further, we have concluded that this rule is not likely to have any significant adverse energy effects. In general, we expect the NSPS to improve technology, including energy efficiency. Reducing emissions and increasing efficiency might increase the use of wood fuel, which would relieve pressure on traditional coal or petroleum based energy sources. However, as described in section VI.E, it is difficult to determine the precise energy impacts that might result from this rule. This is because wood-fueled appliances compete with other biomass forms as well as more traditional oil, electricity and natural gas. Robust data are not available to determine the potential conversion to other types of fuels and their associated appliances if the consumer costs of wood-fueled appliances increase and at what level that increase would drive consumer choice. 43 ‘‘Analysis of Exposure to Residential Wood Combustion Emissions for Different SocioEconomic Groups, Revised Draft Report.’’ Prepared for Gil Wood, U.S. EPA, Office of Air Quality Planning and Standards, Research Triangle Park, NC.

The EPA has decided to use several VCS ASTM International test methods, in full or in part, including the following: • E2515–11 ‘‘Standard Test Method for Determination of Particulate Matter Emissions Collected by a Dilution Tunnel.’’ This test method is applicable for the determination of particulate matter emissions from solid-fuelburning appliances including woodstoves, pellet-burning appliances, factory-built fireplaces, masonry fireplaces, masonry heaters, indoor furnaces, and indoor and outdoor hydronic heaters within a laboratory environment; • E2779–10 ‘‘Standard Test Method for Determining Particulate Matter Emissions from Pellet Heaters.’’ This test method covers the fueling and operating protocol for determining particulate matter emissions from fires in pellet or other granular or particulate biomass burning room heaters and fireplace inserts; • E2780–10 ‘‘Standard Test Method for Determining Particulate Matter Emissions from Wood Heaters.’’ This test method covers the fueling and operating protocol for determining particulate matter emissions from wood fires in wood-burning room heaters and fireplace inserts as well as determining heat output and efficiency; and • E2618–13 ‘‘Standard Test Method for Measurement of Particulate Matter Emissions and Heating Efficiency of Outdoor Solid Fuel-Fired Hydronic Heating Appliances.’’ This test method applies to wood-fired or automatically fed biomass burning hydronic heating appliances. These appliances transfer heat to the indoor environment through circulation of a liquid heat exchange media such as water or a waterantifreeze mixture. In addition, we determined that the VCS ASTM E871–82 (Reapproved 2013), ‘‘Standard Test Method for Moisture Analysis of Particulate Wood Fuels’’ is acceptable as an alternative to that portion of the EPA Methods 5H and 28. ASTM E871–82 (Reapproved 2013) covers the determination of total weight basis moisture in the analysis sample of particulate wood fuel. These VCS test methods are available for purchase from ASTM International, 100 Barr Harbor Drive, P.O. Box CB700, West Conshohocken, Pennsylvania 19428– 2959, (800) 262–1373, https:// www.astm.org.

The telephone number for the Public Reading Room is (202) 566–1744, and the telephone number for the EPA Docket Center is (202) 566–1742. The EPA will also use, in part, the following test VCS CSA method available at the CSA Web site https:// shop.csa.ca/en/canada/fuel-burningequipment/b4151-10/invt/27013322010/ :CSA_B415.1-10 ‘‘Performance Testing of Solid-fuel-burning Heating Appliances.’’ This standard specifies requirements for performance testing of solid-fuel-burning heating appliances, including maximum emission rates. This standard also specifies a method for determining heat outputs, appliance efficiencies, emission levels and composition, and flue gas flow rates. A hard copy of this material is also available for viewing in the docket for this rule (Docket ID# EPA–HQ–OAR– 2009–0734) at the EPA Docket Center located at the address and telephone numbers above. Finally, we will use, in part, the following VCS test method, European National (EN) standard prepared by the European Union: EN 303–5 ‘‘Heating boilers for solid fuels, hand and automatically stoked nominal heat output of up to 1025 MBtu— Terminology, requirements, testing, and marketing.’’ This EN standard applies to heating boilers including safety devices up to a nominal heat output of 500 kilowatts, which are designed for the burning of solid fuels only and are operated according to the instructions of the boiler manufacturer.

A hard copy of this material is also available for viewing in the docket for this rule (Docket ID# EPA– HQ–OAR–2009–0734), at the EPA Docket Center located at the address and telephone numbers above. We believe that all the methods listed above have some positive aspects that can help stakeholders determine emissions under various operation conditions. For more details, please refer to section 6 of the RTC document. The search identified five other VCS that were potentially applicable for this rule in lieu of the EPA reference methods. However, the EPA determined VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 that the five candidate VCS would not be applicable and practical due to lack of equivalency, documentation, validation data and other important technical and policy considerations. The five VCS and other information and conclusion, including the search and review results, are in the docket for this rule. The EPA solicited comments on this aspect of the proposed rulemaking. Specifically, we invited the public to identify potentially applicable voluntary consensus standards and to explain why such standards, in whole or in part, should or should not be used in this regulation. The EPA’s responses to the significant comments are presented in section V of this preamble and in section 6 of the RTC document. J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations The EPA believes the human health or environmental risk addressed by this action will not have potential disproportionately high and adverse human health or environmental effects on minority, low-income or indigenous populations because it does not affect the level of protection provided to human health or the environment. The results of this evaluation are contained in the report ‘‘Analysis of Exposure to Residential Wood Combustion Emissions for Different Socio-Economic Groups’’ which shows that on a nationwide basis, cancer risks due to residential wood smoke emissions among disadvantaged population groups generally are lower than the risks for the general population due to residential wood smoke emissions.44 Rather, the rule increases the level of environmental protection for all affected populations without having any disproportionately high and adverse human health or environmental effects on any population, including any minority, low-income or indigenous population. This rule establishes national standards that will reduce primarily PM emissions from new residential wood heaters and, thus, is expected to decrease the amount of these emissions to which all affected populations are exposed. These emissions happen in many neighborhoods nationwide, including in minority and low-income 44 ‘‘Analysis of Exposure to Residential Wood Combustion Emissions for Different SocioEconomic Groups, Revised Draft Report.’’ Prepared for Gil Wood, U.S. EPA, Office of Air Quality Planning and Standards, Research Triangle Park, NC.

The contract must include regular (at least annual) unannounced audits under ISO–IEC Standard 17065 to ensure that the VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 manufacturer’s quality assurance plan is being implemented. The contract must also include a report for each audit under ISO–IEC Standard 17065 that fully documents the results of the audit. The contract must include authorization and requirement for the third-party certifier to submit all such reports to the Administrator and the manufacturer within 30 days of the audit. The audit report must identify deviations from the manufacturer’s quality assurance plan and specify the corrective actions that need to be taken to address each identified deficiency. (ii) The manufacturer must submit the materials specified in paragraph (b) of this section and a quality assurance plan that meets the requirements of paragraph (m) of this section to the third-party certifier. The quality assurance plan must ensure that units within a model line will be similar in all material respects that would affect emissions to the wood heater submitted for certification testing, and it must include design drawings for the model line. (iii) The manufacturer must apply to the third-party certifier for a certification of conformity with the applicable requirements of this subpart for the model line. (A) After testing by an approved test laboratory is complete, certification of conformity with the emission standards in § 60.5474 must be performed by the manufacturer’s contracted third-party certifier. (B) The third-party certifier may 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 central heater meets the applicable emission limits specified in § 60.5474; and the quality assurance plan is adequate to ensure that units within the model line will be similar in all material respects that would affect emissions to the central heater submitted for certification testing, and that the affected heaters would meet all applicable requirements of this subpart. (iv) The manufacturer must then submit to the Administrator an application for a certificate of compliance that includes the certification of conformity, quality assurance plan, test report and all supporting documentation specified in paragraph (b) of this section. (v) The submission also must include a statement signed by a responsible official of the manufacturer or authorized representative that the PO 00000 Frm 00049 Fmt 4701 Sfmt 4700 13719 manufacturer has complied with and will continue to comply with all requirements of this subpart for certificate of compliance and that the manufacturer remains responsible for compliance regardless of any error by the test laboratory or third-party certifier. (2) The Administrator will issue to the manufacturer a certificate of compliance for a model line if it is determined, based on all of the information submitted in the application for certification and any other relevant information, that: (i) A valid certification of conformity has demonstrated that the representative affected central heater complies with the applicable emission standards in § 60.5474; (ii) Any tolerances or materials for components listed in paragraph (k)(2) or (3) of this section that are different from those specified in those paragraphs may not be reasonably anticipated to cause central heaters in the model line to exceed the applicable emission limits; (iii) The requirements of paragraphs (b) of this section have been met; and (iv) A valid certificate of conformity for the model line has been prepared and submitted. (3) The Administrator will deny certification if the Administrator determines that the criteria in paragraph (f)(2) of this section have not been satisfied. Upon denying certification under this paragraph, the Administrator will give written notice to the manufacturer setting forth the basis for the determination. (g) Waiver from submitting test results. An applicant for certification may apply for a potential waiver of the requirement to submit the results of a certification test pursuant to paragraph (b) of this section, if the central heater meets either of the following conditions: (1) The central heaters of the model line are similar in all material respects that would affect emissions, as defined in § 60.5473 and paragraph (k) of this section, to another model line that has already been issued a certificate of compliance. A manufacturer that seeks a waiver of certification testing must identify the model line that has been certified, and must submit a copy of an agreement with the owner of the design permitting the applicant to produce central heaters of that design. (2) The manufacturer has previously conducted a valid certification test to demonstrate that the central heaters of the model line meet the applicable standard specified in § 60.5474. (h) Certification period. Unless revoked sooner by the Administrator, a certificate of compliance will be valid E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 13720 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations for 5 years from the date of issuance or until a more stringent standard comes into effect, whichever is sooner. (i) Renewal of certification. (1) The manufacturer must renew a model line’s certificate of compliance or recertify the model line every 5 years, or the manufacturer may choose to no longer manufacture or sell that model line after the expiration date. If the manufacturer chooses to no longer manufacture that model line, then the manufacturer must submit a statement to the Administrator to that effect. (2) A manufacturer of an affected residential hydronic heater or forced-air furnace or other central heater may apply to the Administrator for potential renewal of its certificate of compliance by submitting the material specified in paragraph (b) and following the procedures specified in paragraph (f) of this section, or by affirming in writing that the central heaters in the model line continue to be similar in all material respects that would affect emissions to the representative central heater submitted for testing on which the original certificate of compliance was based and requesting a potential waiver from certification testing. The application must include a copy of the review of the draft application and approval by the third-party certifier. (3) If the Administrator grants a renewal of certification, the Administrator will give written notice to the manufacturer setting forth the basis for the determination and issue a certification renewal. (4) If the Administrator denies the request for a renewal of certification, the Administrator will give written notice to the manufacturer setting forth the basis for the determination. (5) If the Administrator denies the request for a renewal of certification, the manufacturer and retailer must not manufacture or sell the previouslycertified central heaters after the expiration date of the certificate of compliance. (j) [Reserved] (k) Recertification. (1) The manufacturer must recertify a model line whenever any change is made in the design submitted pursuant to paragraph (k)(2) of this section that affects or is presumed to affect the particulate matter emission rate for that model line. The manufacturer of an affected central heater must apply to the Administrator for potential recertification by submitting the material specified in paragraph (b) of this section and following the procedures specified in paragraph (f) of this section or by affirming in writing that the change will not cause the VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 central heaters in the model line to exceed applicable emission limits and requesting a waiver from certification testing. The application for recertification must be reviewed and approved by the contracted third-party certifier and a copy of the review and approval must be included. The Administrator may waive this requirement upon written request by the manufacturer, if the manufacturer presents adequate rationale and the Administrator determines that the change may not reasonably be anticipated to cause central heaters in the model line to exceed the applicable emission limits. The granting of such a waiver does not relieve the manufacturer of any compliance obligations under this subpart. (2) Any change in the design tolerances of any of the following components (where such components are applicable) is presumed to affect particulate matter and carbon monoxide emissions and efficiency if that change exceeds ±0.64 cm (±1/4 inch) for any linear dimension and ±5 percent for any cross-sectional area relating to air introduction systems and catalyst bypass gaps unless other dimensions and cross-sectional areas are previously approved by the Administrator under paragraph (c)(1)(ii) of this section: (i) Firebox: Dimensions; (ii) Air introduction systems: Crosssectional area of restrictive air inlets and outlets, location and method of control; (iii) Baffles: Dimensions and locations; (iv) Refractory/insulation: Dimensions and location; (v) Catalyst: Dimensions and location; (vi) Catalyst bypass mechanism and catalyst bypass gap tolerances (when bypass mechanism is in closed position): Dimensions, cross-sectional area, and location; (vii) Flue gas exit: Dimensions and location; (viii) Door and catalyst bypass gaskets: Dimensions and fit; (ix) Outer thermal shielding and thermal coverings: Dimensions and location; (x) Fuel feed system: For central heaters that are designed primarily to burn wood pellet fuel or wood chips and other central heaters equipped with a fuel feed system, the fuel feed rate, auger motor design and power rating, and the angle of the auger to the firebox; and (xi) Forced air combustion system: For central heaters so equipped, the location and horsepower of blower motors and the fan blade size. (3) Any change in the materials used for the following components is PO 00000 Frm 00050 Fmt 4701 Sfmt 4700 presumed to affect particulate matter emissions and efficiency: (i) Refractory/insulation; or (ii) Door and catalyst bypass gaskets. (4) A change in the make, model, or composition of a catalyst is presumed to affect particulate matter and carbon monoxide emissions and efficiency, unless the change has been requested by the central heater manufacturer and has been approved in advance by the Administrator, based on test data that demonstrate that the replacement catalyst is equivalent to or better than the original catalyst in terms of particulate matter emission reduction. (l) Criteria for revocation of certification. (1) The Administrator may revoke certification of a product line if it is determined that the central heaters being manufactured or sold in that model line do not comply with the requirements of this subpart. Such a determination will be based on all available evidence, including but not limited to: (i) Test data from retesting of the original unit on which the certification test was conducted on a unit that is similar in all material respects that would affect emissions; (ii) A finding that the certification test was not valid. The finding will be based on problems or irregularities with the certification test or its documentation, but may be supplemented by other information; (iii) A finding that the labeling of the central heater model line or the owner’s manual or the associated marketing information does not comply with the requirements of § 60.5478; (iv) Failure by the manufacturer to comply with the reporting and recordkeeping requirements of § 60.5479; (v) Physical examination showing that a significant percentage (as defined in the quality assurance plan approved pursuant to paragraph (m) of this section, but no larger than 1 percent) of production units inspected is not similar in all material respects that would affect emissions to the representative affected central heater submitted for certification testing; or (vi) Failure of the manufacturer to conduct a quality assurance program in conformity with paragraph (m).

Upon request, four-inch filters may be used. Upon request, Teflon membrane filters or Teflon-coated glass fiber filters may be used. 2.0 Procedures 2.1 This method incorporates the provisions of ASTM E2780–10 (IBR, see § 60.17) except as follows: 2.1.1 The burn rate categories, low burn rate requirement, and weightings in Method 28 shall be used. 2.1.2 The startup procedures shall be the same as in Method 28. 2.1.3 Manufacturers shall not specify a smaller volume of the firebox for testing than the full usable firebox. 2.1.4 Prior to testing, the heater must be operated for a minimum of 50 hours using a medium burn rate. The conditioning may be at the manufacturer’s facility prior to the certification test. If the conditioning is at the certification test laboratory, the pre-burn for the first test can be included as part of the conditioning requirement. 2.2 Manufacturers may use ASTM E871– 82 (reapproved 2013) (IBR, see § 60.17) as an alternative to the procedures in Method 5H or Method 28 for determining total weight basis moisture in the analysis sample of particulate wood fuel. mstockstill on DSK4VPTVN1PROD with RULES2 Test Method 28WHH for Measurement of Particulate Emissions and Heating Efficiency of Wood-Fired Hydronic Heating Appliances 1.0 Scope and Application 1.1 This test method applies to woodfired hydronic heating appliances. The units typically transfer heat through circulation of a liquid heat exchange media such as water or a water-antifreeze mixture. 1.2 The test method measures particulate emissions and delivered heating efficiency at specified heat output rates based on the appliance’s rated heating capacity. 1.3 Particulate emissions are measured by the dilution tunnel method as specified in ASTM E2515–11 Standard Test Method for Determination of Particulate Matter Emissions Collected in a Dilution Tunnel (IBR, see § 60.17). Upon request, four-inch filters may be used. Upon request, Teflon membrane filters or Teflon-coated glass fiber filters may be used. Delivered efficiency is measured by determining the heat output through measurement of the flow rate and temperature change of water circulated through a heat exchanger external to the appliance and determining the input from the mass of dry wood fuel and its higher VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 heating value. Delivered efficiency does not attempt to account for pipeline loss. 1.4 Products covered by this test method include both pressurized and nonpressurized heating appliances intended to be fired with wood. These products are wood-fired hydronic heating appliances that the manufacturer specifies for indoor or outdoor installation. They are often connected to a heat exchanger by insulated pipes and normally include a pump to circulate heated liquid. They are used to heat structures such as homes, barns and greenhouses and can heat domestic hot water, spas or swimming pools. 1.5 Distinguishing features of products covered by this standard include: 1.5.1 Manufacturer specifies for indoor or outdoor installation. 1.5.2 A firebox with an access door for hand loading of fuel. 1.5.3 Typically, an aquastat that controls combustion air supply to maintain the liquid in the appliance within a predetermined temperature range provided sufficient fuel is available in the firebox. 1.5.4 A chimney or vent that exhausts combustion products from the appliance. 1.6 The values stated are to be regarded as the standard whether in I–P or SI units.

Emissions are determined using the ‘‘dilution tunnel’’ method specified in ASTM E2515–11 Standard Test Method for Determination of Particulate Matter Emissions Collected in a Dilution Tunnel (IBR, see § 60.17). The flow rate in the dilution tunnel is maintained at a constant level throughout the test cycle and accurately measured. Samples of the dilution tunnel flow stream are extracted at a constant flow rate and drawn through high efficiency filters. The filters are dried and weighed before and after the test to determine the emissions catch and this value is multiplied by the ratio of tunnel flow to filter flow to determine the total particulate emissions produced in the test cycle. 4.2 Efficiency. The efficiency test procedure takes advantage of the fact that this type of appliance delivers heat through circulation of the heated liquid (water) from the appliance to a remote heat exchanger and back to the appliance. Measurements of the water temperature difference as it enters and exits the heat exchanger along with the measured flow rate allow for an accurate determination of the useful heat output of the appliance. The input is determined by weight of the test fuel charge, adjusted for moisture content, multiplied by the higher heating value. Additional measurements of the appliance weight and temperature at the beginning and end of a test cycle are used to correct for heat stored in the appliance. Overall efficiency (SLM) is determined using the CSA B415.1–10 (IBR, see § 60.17) stack loss method for data quality assurance purposes. 4.3 Operation. Appliance operation is conducted on a hot-to-hot test cycle meaning E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations that the appliance is brought to operating temperature and a coal bed is established prior to the addition of the test fuel charge and measurements are made for each test fuel charge cycle. The measurements are made under constant heat draw conditions within predetermined ranges. No attempt is made to modulate the heat demand to simulate an indoor thermostat cycling on and off in response to changes in the indoor environment. Four test categories are used. These are: 4.3.1 Category I: A heat output of 15 percent or less of manufacturer’s rated heat output capacity. 4.3.2 Category II: A heat output of 16 percent to 24 percent of manufacturer’s rated heat output capacity. 4.3.3 Category III: A heat output of 25 percent to 50 percent of manufacturer’s rated heat output capacity. 4.3.4 Category IV: Manufacturer’s rated heat output capacity. mstockstill on DSK4VPTVN1PROD with RULES2 5.0 Significance and Use 5.1 The measurement of particulate matter emission rates is an important test method widely used in the practice of air pollution control. 5.1.1 These measurements, when approved by state or federal agencies, are often required for the purpose of determining compliance with regulations and statutes. 5.1.2 The measurements made before and after design modifications are necessary to demonstrate the effectiveness of design changes in reducing emissions and make this standard an important tool in manufacturers’ research and development programs. 5.2 Measurement of heating efficiency provides a uniform basis for comparison of product performance that is useful to the consumer. It is also required to relate emissions produced to the useful heat production. 5.3 This is a laboratory method and is not intended to be fully representative of all actual field use.

The average of the outlet and return water temperature on the supply side of the system shall be considered the average appliance temperature for calculation of heat storage in the appliance (TFavg and TIavg). Installation of a water flow meter in the supply side of the system is optional. 9.6 Fill the system with water. Determine the total weight of the water in the appliance when the water is circulating. Verify that the scale indicates a stable weight under operating conditions. Make sure air is purged properly. 10.0 Calibration and Standardization 10.1 Water Temperature Sensors. Temperature measuring equipment shall be calibrated before initial use and at least semiannually thereafter. Calibrations shall be in E:\FR\FM\16MRR2.SGM 16MRR2 13730 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations compliance with National Institute of Standards and Technology (NIST) Monograph 175, Standard Limits of Error. 10.2 Heat Exchanger Load Side Water Flow Meter. 10.2.1 The heat exchanger load side water flow meter shall be calibrated within the flow range used for the test run using NIST traceable methods. Verify the calibration of the water flow meter before and after each test run and at least once during each test run by comparing the water flow rate indicated by the flow meter to the mass of water collected from the outlet of the heat exchanger over a timed interval. Volume of the collected water shall be determined based on the water density calculated from section 13, Eq. 8, using the water temperature measured at the flow meter. The uncertainty in the verification procedure used shall be 1 percent or less. The water flow rate determined by the collection and weighing method shall be within 1 percent of the flow rate indicated by the water flow meter. 10.3 Scales. The scales used to weigh the appliance and test fuel charge shall be calibrated using NIST traceable methods at least once every 6 months. 10.4 Moisture Meter. The moisture meter shall be calibrated per the manufacturer’s instructions and checked before each use. 10.5 Flue Gas Analyzers—In accordance with CSA B415.1–10 (IBR, see § 60.17), clause 6.8. mstockstill on DSK4VPTVN1PROD with RULES2 11.0 Conditioning 11.1 Prior to testing, the appliance is to be operated for a minimum of 50 hours using a medium heat draw rate. The conditioning may be at the manufacturer’s facility prior to the certification test. If the conditioning is at the certification test laboratory, the pre-burn for the first test can be included as part of the conditioning requirement. If conditioning is included in pre-burn, then the appliance shall be aged with fuel meeting the specifications outlined in sections 12.2 with a moisture content between 19 and 25 percent on a dry basis. Operate the appliance at a medium burn rate (Category II or III) for at least 10 hours for noncatalytic appliances and 50 hours for catalytic appliances. Record and report hourly flue gas exit temperature data and the hours of operation. The aging procedure shall be conducted and documented by a testing laboratory. 12.0 Procedure 12.1 Appliance Installation. Assemble the appliance and parts in conformance with the manufacturer’s written installation instructions. Clean the flue with an appropriately sized, wire chimney brush before each certification test series. 12.2 Fuel. Test fuel charge fuel shall be red (Quercus ruba L.) or white (Quercus alba) oak 19 to 25 percent moisture content on a dry basis. Piece length shall be 80 percent of the firebox depth rounded down to the nearest 1 inch (25mm) increment. For example, if the firebox depth is 46 inches (1168mm) the 4 x 4 piece length would be 36 inches (46 inches × 0.8 = 36.8 inches rounded down to 36 inches). Pieces are to be placed in the firebox parallel to the longest firebox dimension. For fireboxes with sloped VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 surfaces that create a non-uniform firebox length, the piece length shall be adjusted for each layer based on 80 percent of the length at the level where the layer is placed. Pieces are to be spaced 3⁄4 inches (19 mm) apart on all faces. The first fuel layer may be assembled using fuel units consisting of multiple 4 x 4s consisting of single pieces with bottom and side spacers of 3 or more pieces if needed for a stable layer. The second layer may consist of fuel units consisting of no more than two pieces with spacers attached on the bottom and side. The top two layers of the fuel charge must consist of single pieces unless the fuel charge is only three layers. In that instance only the top layer must consist of single units. Threequarter inch (19 mm) by 1.5 inch (38 mm) spacers shall be attached to the bottom of piece to maintain a 3⁄4 inch (19 mm) separation. When a layer consists of two or more units of 4 x 4s an additional 3⁄4 inch (19 mm) thick by 1.5 inch (38 mm) wide spacer shall be attached to the vertical face of each end of one 4 x 4, such that the 3⁄4 inch (19 mm) space will be maintained when two 4 x 4 units or pieces are loaded side by side. In cases where a layer contains an odd number of 4 x 4s one piece shall not be attached, but shall have spacers attached in a manner that will provide for the 3⁄4 inch (19 mm) space to be maintained (See Figure 1). Spacers shall be attached perpendicular to the length of the 4 x 4s such that the edge of the spacer is 1 ± 0.25 inch from the end of the 4 x 4s in the previous layers. Spacers shall be red or white oak and will be attached with either nails (non-galvanized), brads or oak dowels. The use of kiln-dried wood is not allowed. 12.2.1 Using a fuel moisture meter as specified in section 6.7 of the test method, determine the fuel moisture for each test fuel piece used for the test fuel load by averaging at least five fuel moisture meter readings measured parallel to the wood grain. Penetration of the moisture meter insulated electrodes for all readings shall be 1⁄4 the thickness of the fuel piece or 19 mm (3⁄4 in.), whichever is lesser. One measurement from each of three sides shall be made at approximately 3 inches from each end and the center. Two additional measurements shall be made centered between the other three locations. Each individual moisture content reading shall be in the range of 18 to 28 percent on a dry basis. The average moisture content of each piece of test fuel shall be in the range of 19 to 25 percent. It is not required to measure the moisture content of the spacers. Moisture shall not be added to previously dried fuel pieces except by storage under high humidity conditions and temperature up to 100 °F. Fuel moisture shall be measured within 4 hours of using the fuel for a test. 12.2.2 Firebox Volume. Determine the firebox volume in cubic feet. Firebox volume shall include all areas accessible through the fuel loading door where firewood could reasonably be placed up to the horizontal plane defined by the top of the loading door. A drawing of the firebox showing front, side and plan views or an isometric view with interior dimensions shall be provided by the manufacturer and verified by the laboratory. PO 00000 Frm 00060 Fmt 4701 Sfmt 4700 Calculations for firebox volume from computer aided design (CAD) software programs are acceptable and shall be included in the test report if used. If the firebox volume is calculated by the laboratory the firebox drawings and calculations shall be included in the test report. 12.2.3 Test Fuel Charge. Test fuel charges shall be determined by multiplying the firebox volume by 10 pounds (4.54 kg) per ft3 (28L), or a higher load density as recommended by the manufacturer’s printed operating instructions, of wood (as used wet weight). Select the number of pieces of standard fuel that most nearly match this target weight. This is the standard fuel charge for all tests. For example, if the firebox loading area volume is 10 ft3 (280L) and the firebox depth is 46 inches (1168 mm), test fuel charge target is 100 lbs (45 kg) minimum and the piece length is 36 inches (914 mm). If eight 4 x 4s, 36 inches long weigh 105 lbs (48 kg), use 8 pieces for each test fuel charge. All test fuel charges will be of the same configuration. 12.3 Sampling Equipment. Prepare the particulate emission sampling equipment as defined by ASTM E2515–11 Standard Test Method for Determination of Particulate Matter Emissions Collected in a Dilution Tunnel (IBR, see § 60.17). Upon request, fourinch filters may be used. Upon request, Teflon membrane filters or Teflon-coated glass fiber filters may be used. 12.4 Appliance Startup. The appliance shall be fired with wood fuel of any species, size and moisture content at the laboratories’ discretion to bring it up to operating temperature. Operate the appliance until the water is heated to the upper operating control limit and has cycled at least two times. Then remove all unburned fuel, zero the scale and verify the scales accuracy using dead weights. 12.4.1 Pretest Burn Cycle. Reload appliance with oak wood and allow it to burn down to the specified coal bed weight. The pretest burn cycle fuel charge weight shall be within ± 10 percent of the test fuel charge weight. Piece size and length shall be selected such that charcoalization is achieved by the time the fuel charge has burned down to the required coal bed weight. Pieces with a maximum thickness of approximately 2 inches have been found to be suitable. Charcoalization is a general condition of the test fuel bed evidenced by an absence of large pieces of burning wood in the coal bed and the remaining fuel pieces being brittle enough to be broken into smaller charcoal pieces with a metal poker. Manipulations to the fuel bed prior to the start of the test run are to be done to achieve charcoalization while maintaining the desired heat output rate. During the pre-test burn cycle and at least one hour prior to starting the test run, adjust water flow to the heat exchanger to establish the target heat draw for the test. For the first test run the heat draw rate shall be equal to the manufacturer’s rated heat output capacity. 12.4.1.1 Allowable Adjustments. Fuel addition or subtractions, and coal bed raking shall be kept to a minimum but are allowed up to 15 minutes prior to the start of the test E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations run. For the purposes of this method, coal bed raking is the use of a metal tool (poker) to stir coals, break burning fuel into smaller pieces, dislodge fuel pieces from positions of poor combustion, and check for the condition of charcoalization. Record all adjustments to and additions or subtractions of fuel, and any other changes to the appliance operations that occur during pretest ignition period. During the 15-minute period prior to the start of the test run, the wood heater loading door shall not be open more than a total of 1 minute. Coal bed raking is the only adjustment allowed during this period. 12.4.2 Coal Bed Weight. The appliance is to be loaded with the test fuel charge when the coal bed weight is between 10 percent and 20 percent of the test fuel charge weight. Coals may be raked as necessary to level the coal bed but may only be raked and stirred once between 15 to 20 minutes prior to the addition of the test fuel charge. 12.5 Test Runs. For all test runs, the return water temperature to the hydronic heater must be equal to or greater than 120 °F. Aquastat or other heater output control device settings that are adjustable shall be set using manufacturer specifications, either as factory set or in accordance with the owner’s manual, and shall remain the same for all burn categories. Complete a test run in each heat output rate category, as follows: 12.5.1 Test Run Start. Once the appliance is operating normally and the pretest coal bed weight has reached the target value per section 12.4.2, tare the scale and load the full test charge into the appliance. Time for loading shall not exceed 5 minutes. The actual weight of the test fuel charge shall be measured and recorded within 30 minutes prior to loading. Start all sampling systems. 12.5.1.1 Record all water temperatures, differential water temperatures and water flow rates at time intervals of one minute or less. 12.5.1.2 Record particulate emissions data per the requirements of ASTM E2515 (IBR, see § 60.17). 12.5.1.3 Record data needed to determine overall efficiency (SLM) per the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 6.2.1, 6.2.2, 6.3, 8.5.7, 10.4.3 (a), 10.4.3(f), and 13.7.9.3 12.5.1.3.1 Measure and record the test room air temperature in accordance with the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 6.2.1, 8.5.7 and 10.4.3 (g). 12.5.1.3.2 Measure and record the flue gas temperature in accordance with the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 6.2.2, 8.5.7 and 10.4.3 (f). 12.5.1.3.3 Determine and record the carbon monoxide (CO) and carbon dioxide (CO2) concentrations in the flue gas in accordance with CSA B415.1–10 (IBR, see § 60.17), clauses 6.3, 8.5.7 and 10.4.3 (i) and (j). 12.5.1.3.4 Measure and record the test fuel weight per the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 8.5.7 and 10.4.3 (h). 12.5.1.3.5 Record the test run time per the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 10.4.3 (a). 12.5.1.4 Monitor the average heat output rate on the load side of the heat exchanger. VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 If the heat output rate gets close to the upper or lower limit of the target range (±5 percent) adjust the water flow through the heat exchanger to compensate. Make changes as infrequently as possible while maintaining the target heat output rate. The first test run shall be conducted at the Category IV heat output rate to validate that the appliance is capable of producing the manufacturer’s rated heat output capacity. 12.5.2 Test Fuel Charge Adjustment. It is acceptable to adjust the test fuel charge (i.e., reposition) once during a test run if more than 60 percent of the initial test fuel charge weight has been consumed and more than 10 minutes have elapsed without a measurable (1 lb or 0. 5 kg) weight change while the operating control is in the demand mode. The time used to make this adjustment shall be less than 60 seconds. 12.5.3 Test Run Completion. The test run is completed when the remaining weight of the test fuel charge is 0.0 lb (0.0 kg). End the test run when the scale has indicated a test fuel charge weight of 0.0 lb (0.0 kg) or less for 30 seconds. 12.5.3.1 At the end of the test run, stop the particulate sampling train and overall efficiency (SLM) measurements, and record the run time, and all final measurement values. 12.5.4 Heat Output Capacity Validation. The first test run must produce a heat output rate that is within 10 percent of the manufacturer’s rated heat output capacity (Category IV) throughout the test run and an average heat output rate within 5 percent of the manufacturer’s rated heat output capacity. If the appliance is not capable of producing a heat output within these limits, the manufacturer’s rated heat output capacity is considered not validated and testing is to be terminated. In such cases, the tests may be restarted using a lower heat output capacity if requested by the manufacturer. 12.5.5 Additional Test Runs. Using the manufacturer’s rated heat output capacity as a basis, conduct a test for additional heat output categories as specified in section 4.3. It is not required to run these tests in any particular order. 12.5.6 Alternative Heat Output Rate for Category I. If an appliance cannot be operated in the Category I heat output range due to stopped combustion, two test runs shall be conducted at heat output rates within Category II, provided that the completed test run burn rate is no greater than the burn rate expected in home use. If this rate cannot be achieved, the test is not valid. When the alternative heat output rate is used, the weightings for the weighted averages indicated in Table 2 shall be the average of the Category I and II weightings and shall be applied to both Category II results. The two completed runs in Category II will be deemed to meet the requirement for runs completed in both Category I and Category II. Appliances that are not capable of operation within Category II (<25 percent of maximum) cannot be evaluated by this test method. The test report must include full documentation and discussion of the attempted runs, completed rums and calculations. 12.5.6.1 Stopped Fuel Combustion. Evidence that an appliance cannot be PO 00000 Frm 00061 Fmt 4701 Sfmt 4700 13731 operated at a Category I heat output rate due to stopped fuel combustion shall include documentation of two or more attempts to operate the appliance in burn rate Category I and fuel combustion has stopped prior to complete consumption of the test fuel charge. Stopped fuel combustion is evidenced when an elapsed time of 60 minutes or more has occurred without a measurable (1 lb or 0.5 kg) weight change in the test fuel charge while the appliance operating control is in the demand mode. Report the evidence and the reasoning used to determine that a test in burn rate Category I cannot be achieved. For example, two unsuccessful attempts to operate at an output rate of 10 percent of the rated output capacity are not sufficient evidence that burn rate Category I cannot be achieved. Note that section 12.5.6 requires that the completed test run burn rate can be no greater than the burn rate expected in home use. If this rate cannot be achieved, the test is not valid. 12.5.7 Appliance Overheating. Appliances shall be capable of operating in all heat output categories without overheating to be rated by this test method. Appliance overheating occurs when the rate of heat withdrawal from the appliance is lower than the rate of heat production when the unit control is in the idle mode. This condition results in the water in the appliance continuing to increase in temperature well above the upper limit setting of the operating control. Evidence of overheating includes: 1 hour or more of appliance water temperature increase above the upper temperature set-point of the operating control, exceeding the temperature limit of a safety control device (independent from the operating control), boiling water in a non-pressurized system or activation of a pressure or temperature relief valve in a pressurized system. 12.6 Additional Test Runs.

The units typically transfer heat through circulation of a liquid heat exchange media such as water or a water-antifreeze mixture. Throughout this document, the term ‘‘water’’ will be used to denote any of the heat transfer liquids approved for use by the manufacturer. 1.2 The test method measures PM and CO emissions and delivered heating efficiency at specified heat output rates referenced against the appliance’s rated heating capacity as specified by the manufacturer and verified under this test method. 1.3 PM emissions are measured by the dilution tunnel method as specified in the EPA Method 28WHH and the standards VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 referenced therein with the exceptions noted in section 12.5.9. Delivered efficiency is measured by determining the fuel energy input and appliance output. Heat output is determined through measurement of the flow rate and temperature change of water circulated through a heat exchanger external to the appliance and the increase in energy of the external storage. Heat input is determined from the mass of dry wood fuel and its higher heating value (HHV). Delivered efficiency does not attempt to account for pipeline loss. 1.4 Products covered by this test method include both pressurized and nonpressurized hydronic heating appliances intended to be fired with wood and for which the manufacturer specifies for indoor or outdoor installation. The system, which includes the heating appliance and external storage, is commonly connected to a heat exchanger by insulated pipes and normally includes a pump to circulate heated liquid. These systems are used to heat structures such as homes, barns and greenhouses. They also provide heat for domestic hot water, spas and swimming pools.

The boiler/heater at the start of this test is typically 125° to 130 °F. 3.1.14 Test Run Under ‘‘Hot-to-Hot’’ Condition—Under this test condition the test fuel is added onto a still-burning bed of charcoals produced in a pre-burn period. The boiler/heater water is near its operating control limit at the start of the test. 3.1.15 Overall Efficiency, also known as Stack Loss Efficiency—The efficiency for each test run as determined using the CSA B415.1–10 (IBR, see § 60.17) stack loss method (SLM). 3.1.16 Phases of a Burn Cycle—The ‘‘startup phase’’ is defined as the period from the start of the test until 15 percent of the test fuel charge is consumed. The ‘‘steady-state phase’’ is defined as the period from the end of the startup phase to a point at which 80 percent of the test fuel charge is consumed. The ‘‘end phase’’ is defined as the time from the end of the steady-state period to the end of the test. 3.1.17 Thermopile—A device consisting of a number of thermocouples connected in series, used for measuring differential temperature. 3.1.18 Slumber Mode—This is a mode in which the temperature of the water in the boiler/heater has exceeded the operating control limit and the control has changed the boiler/heater fan speed, dampers, and/or other operating parameters to minimize the heat output of the boiler/heater. 4.0 Summary of Test Method 4.1 Dilution Tunnel. Emissions are determined using the ‘‘dilution tunnel’’ method specified in EPA Method 28WHH and the standards referenced therein. The flow rate in the dilution tunnel is maintained at a constant level throughout the test cycle and accurately measured. Samples of the dilution tunnel flow stream are extracted at a constant flow rate and drawn through high efficiency filters. The filters are dried and weighed before and after the test to determine the emissions collected and this value is multiplied by the ratio of tunnel flow to filter flow to determine the total particulate emissions produced in the test cycle. 4.2 Efficiency. The efficiency test procedure takes advantage of the fact that this type of system delivers heat through circulation of the heated liquid (water) from the system to a remote heat exchanger (e.g. baseboard radiators in a room) and back to the system. Measurements of the cooling water temperature difference as it enters and exits the test system heat exchanger along with the measured flow rate allow for an accurate determination of the useful heat output of the appliance. Also included in the heat output is the change in the energy content in the storage system during a test PO 00000 Frm 00068 Fmt 4701 Sfmt 4700 run. Energy input to the appliance during the test run is determined by weight of the test fuel charge, adjusted for moisture content, multiplied by the higher heating value. Additional measurements of the appliance weight and temperature at the beginning and end of a test cycle are used to correct for heat stored in the appliance. Overall efficiency (SLM) is determined using the CSA B415.1– 10 (IBR, see § 60.17) stack loss method for data quality assurance purposes. 4.3 Operation. Four test categories are defined for use in this method. These are: 4.3.1 Category I: A heat output of 15 percent or less of manufacturer’s rated heat output capacity. 4.3.2 Category II: A heat output of 16 percent to 24 percent of manufacturer’s rated heat output capacity. 4.3.3 Category III: A heat output of 25 percent to 50 percent of manufacturer’s rated heat output capacity. 4.3.4 Category IV: Manufacturer’s Rated Heat Output Capacity. These heat output categories refer to the output from the system by way of the load heat exchanger installed for the test. The output from just the boiler/ heater part of the system may be higher for all or part of a test, as part of this boiler/ heater output goes to storage. For the Category III and IV runs, appliance operation is conducted on a hot-to-hot test cycle meaning that the appliance is brought to operating temperature and a coal bed is established prior to the addition of the test fuel charge and measurements are made for each test fuel charge cycle. The measurements are made under constant heat draw conditions within pre-determined ranges. No attempt is made to modulate the heat demand to simulate an indoor thermostat cycling on and off in response to changes in the indoor environment. For the Category I and II runs, the unit is tested with a ‘‘cold start.’’ At the manufacturer’s option, the Category II and III runs may be waived and it may be assumed that the particulate emission values and efficiency values determined in the startup, steady-state, and end phases of Category I are applicable in Categories II and III for the purpose of determining the annual averages in lb/mmBtu and g/MJ (See section 13). For the annual average in g/hr, the length of time for stored heat to be drawn from thermal storage shall be determined for the test load requirements of the respective category. All test operations and measurements shall be conducted by personnel of the laboratory responsible for the submission of the test report. 5.0 Significance and Use 5.1 The measurement of particulate matter emission and CO rates is an important test method widely used in the practice of air pollution control. 5.1.1 These measurements, when approved by state or federal agencies, are often required for the purpose of determining compliance with regulations and statutes. 5.1.2 The measurements made before and after design modifications are necessary to demonstrate the effectiveness of design changes in reducing emissions and make this standard an important tool in manufacturers’ research and development programs.

It is also required to relate emissions produced to the useful heat production. 5.3 This is a laboratory method and is not intended to be fully representative of all actual field use.

If no flue or chimney system is recommended or provided by the manufacturer, connect the appliance to a flue of a diameter equal to the flue outlet of the appliance. The flue section from the appliance flue collar to 8 ±0.5 feet above the scale shall be single wall stove pipe and the remainder of the flue shall be double wall insulated class A chimney. 9.3 Optional Equipment Use 9.3.1 A recirculation pump may be installed between connections at the top and bottom of the appliance to minimize thermal stratification if specified by the manufacturer. The pump shall not be installed in such a way as to change or affect the flow rate between the appliance and the heat exchanger. 9.3.2 If the manufacturer specifies that a thermal control valve or other device be installed and set to control the return water temperature to a specific set point, the valve or other device shall be installed and set per the manufacturer’s written instructions. 9.4 Prior to filling the boiler/heater with water, weigh and record the appliance mass. 9.5 Heat Exchanger 9.5.1 Plumb the unit to a water-to-water heat exchanger with sufficient capacity to draw off heat at the maximum rate anticipated. Route hoses and electrical cables and instrument wires in a manner that does not influence the weighing accuracy of the scale as indicated by placing dead weights on the platform and verifying the scale’s accuracy. 9.5.2 Locate thermocouples to measure the water temperature at the inlet and outlet of the load side of the heat exchanger. 9.5.3 Install a thermopile (or equivalent instrumentation) meeting the requirements of section 6.3 to measure the water temperature difference between the inlet and outlet of the load side of the heat exchanger 9.5.4 Install a calibrated water flow meter in the heat exchanger load side supply line. The water flow meter is to be installed on the cooling water inlet side of the heat exchanger so that it will operate at the temperature at which it is calibrated. 9.5.5 Place the heat exchanger in a box with 2 in.

The storage tank shall include a destratification pump as illustrated in Figure 1. The pump will draw from the bottom of the tank and return to the top as illustrated. Temperature sensors (TS1 and TS2 in Figure 1) shall be included to measure the temperature in the recirculation loop. The valve plan in Figure 1 allows the tank recirculation loop to operate and the boiler/ heater-to-heat exchanger loop to operate at the same time but in isolation. This would typically be done before the start of a test or following completion of a test to determine the end of test average tank temperature. The nominal flow rate in the storage tank recirculation loop can be estimated based on pump manufacturers’ performance curves and any significant restriction in the recirculation loop. 9.7 Fill the system with water. Determine the total weight of the water in the appliance when the water is circulating. Verify that the scale indicates a stable weight under operating conditions. Make sure air is purged properly. mstockstill on DSK4VPTVN1PROD with RULES2 10.0 Calibration and Standardization 10.1 Water Temperature Sensors. Temperature measuring equipment shall be calibrated before initial use and at least semiannually thereafter. Calibrations shall be in compliance with National Institute of Standards and Technology (NIST) Monograph 175, Standard Limits of Error. 10.2 Heat Exchanger Load Side Water Flow Meter. 10.2.1 The heat exchanger load side water flow meter shall be calibrated within the flow range used for the test run using NISTtraceable methods. Verify the calibration of the water flow meter before and after each test run and at least once during each test run by comparing the water flow rate indicated by the flow meter to the mass of water collected from the outlet of the heat Where: WSliceWet = weight of the slice before drying in pounds WSliceDry = weight of the slice after drying in pounds MCSlice = moisture content of the slice in % dry basis The average moisture content of the entire test load (MC) shall be determined using Eq. 6. Each individual slice shall have a moisture content in the range of 18 percent to 28 percent on a dry basis. The average moisture content for the test fuel load shall be in the range of 19 percent to 25 percent. Moisture shall not be added to previously dried fuel pieces except by storage under high humidity conditions and temperature up to 100 °F. Fuel moisture measurement shall begin within 4 hours of using the fuel batch for a test. Use of a pin-type meter to estimate the moisture content prior to a test is recommended. 12.2.2 Firebox Volume. Determine the firebox volume in cubic feet. Firebox volume VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 12.0 Procedure 12.1 Appliance Installation. Assemble the appliance and parts in conformance with the manufacturer’s written installation instructions. Clean the flue with an appropriately sized, wire chimney brush before each certification test series. 12.2 Fuel. Test fuel charge fuel shall be red (Quercus ruba L.) or white (Quercus Alba) oak 19 to 25 percent moisture content on a dry basis. Piece length shall be 80 percent of the firebox depth rounded down to the nearest 1 inch (25mm) increment. For example, if the firebox depth is 46 inches (1168mm) the piece length would be 36 inches (46 inches x 0.8 = 36.8 inches, rounded down to 36 inches). Pieces are to be placed in the firebox parallel to the longest firebox dimension. For fireboxes with sloped surfaces that create a non-uniform firebox length, the piece length shall be adjusted for each layer based on 80 percent of the length at the level where the layer is placed. The test fuel shall be cord wood with cross section dimensions and weight limits as defined in CSA B415.1–10 (IBR, see § 60.17), section 8.3, Table 4. The use of dimensional lumber is not allowed. 12.2.1 Select three pieces of cord wood from the same batch of wood as the test fuel and the same weight as the average weight of the pieces in the test load ± 1.0 lb. From each of these three pieces, cut three slices. Each slice shall be 1⁄2 inch to 3⁄4 inch thick. One slice shall be cut across the center of the length of the piece. The other two slices shall be cut half way between the center and the end. Immediately measure the mass of each piece in pounds. Dry each slice in an oven at 220 °F for 24 hours or until no further weight change occurs. The slices shall be arranged in the oven so as to provide separation between faces. Remove from the oven and measure the mass of each piece again as soon as practical, in pounds. The moisture content of each slice, on a dry basis, shall be calculated as: shall include all areas accessible through the fuel loading door where firewood could reasonably be placed up to the horizontal plane defined by the top of the loading door. A drawing of the firebox showing front, side and plan views or an isometric view with interior dimensions shall be provided by the manufacturer and verified by the laboratory. Calculations for firebox volume from computer aided design (CAD) software programs are acceptable and shall be included in the test report if used. If the firebox volume is calculated by the laboratory the firebox drawings and calculations shall be included in the test report. 12.2.3 Test Fuel charge. Test fuel charges shall be determined by multiplying the firebox volume by 10 pounds (4.54 kg) per ft3 (28L), or a higher load density as recommended by the manufacturer’s printed operating instructions, of wood (as used wet weight). Select the number of pieces of cord wood that most nearly match this target weight. However, the test fuel charge cannot be less than the target of 10 pounds (4.54 kg) per ft3 (28L). 12.3 Sampling Equipment. Prepare the particulate emission sampling equipment as defined by EPA Method 28WHH and the standards referenced therein. 12.4 Appliance Startup. The appliance shall be fired with wood fuel of any species, size and moisture content, at the laboratory’s discretion, to bring it up to operating temperature. Operate the appliance until the water is heated to the upper operating control limit and has cycled at least two times. Then remove all unburned fuel, zero the scale and verify the scales accuracy using dead weights. 12.4.1 Startup Procedure for Category III and IV Test Runs, ‘‘Hot-to-Hot.’’ 12.4.1.1 Pretest t Burn Cycle. Following appliance startup (section 12.4), reload appliance with oak cord wood and allow it to burn down to the specified coal bed weight. The pre-test burn cycle fuel charge exchanger over a timed interval. Volume of the collected water shall be determined based on the water density calculated from section 13, Eq. 12, using the water temperature measured at the flow meter. The uncertainty in the verification procedure used shall be 1 percent or less. The water flow rate determined by the collection and weighing method shall be within 1 percent of the flow rate indicated by the water flow meter. 10.3 Scales. The scales used to weigh the appliance and test fuel charge shall be calibrated using NIST-traceable methods at least once every 6 months. 10.4 Flue Gas Analyzers—In accordance with CSA B415.1–10 (IBR, see § 60.17), clause 6.8. 11.0 Conditioning 11.1 Prior to testing, an appliance is to be operated for a minimum of 50 hours using a medium heat draw rate. The conditioning may be at the manufacturer’s facility prior to the certification test. If the conditioning is at the certification test laboratory, the pre-burn for the first test can be included as part of the conditioning requirement. If conditioning is included in pre-burn, then the appliance shall be aged with fuel meeting the specifications outlined in section 12.2 with a moisture content between 19 and 25 percent on a dry basis. Operate the appliance at a medium heat output rate (Category II or III) for at least 10 hours for non-catalytic appliances and 50 hours for catalytic appliances. Record and report hourly flue gas exit temperature data and the hours of operation. The aging procedure shall be conducted and documented by a testing laboratory.

Piece size and length shall be selected such that charcoalization is achieved by the time the fuel charge has burned down to the required coal bed weight. Pieces with a maximum thickness of approximately 2 inches have been found to be suitable. Charcoalization is a general condition of the test fuel bed evidenced by an absence of large pieces of burning wood in the coal bed and the remaining fuel pieces being brittle enough to be broken into smaller charcoal pieces with a metal poker. Manipulations to the fuel bed prior to the start of the test run are to be done to achieve charcoalization while maintaining the desired heat output rate. During the pre-test burn cycle and at least one hour prior to starting the test run, adjust water flow to the heat exchanger to establish the target heat draw for the test. For the first test run the heat draw rate shall be equal to the manufacturer’s rated heat output capacity. 12.4.1.2 Allowable Adjustments. Fuel addition or subtractions, and coal bed raking shall be kept to a minimum but are allowed up to 15 minutes prior to the start of the test run. For the purposes of this method, coal bed raking is the use of a metal tool (poker) to stir coals, break burning fuel into smaller pieces, dislodge fuel pieces from positions of poor combustion, and check for the condition of charcoalization. Record all adjustments to and additions or subtractions of fuel, and any other changes to the appliance operations that occur during pretest ignition period. During the 15-minute period prior to the start of the test run, the wood heater loading door shall not be open more than a total of 1 minute. Coal bed raking is the only adjustment allowed during this period. 12.4.1.3 Coal Bed Weight. The appliance is to be loaded with the test fuel charge when the coal bed weight is between 10 percent and 20 percent of the test fuel charge weight. Coals may be raked as necessary to level the coal bed but may only be raked and stirred once between 15 to 20 minutes prior to the addition of the test fuel charge. 12.4.1.4 Storage. The Category III and IV test runs may be done either with or without the thermal storage. If thermal storage is used, the initial temperature of the storage must be 125 °F or greater at the start of the test. The storage may be heated during the pre-test burn cycle or it may be heated by external means. If thermal storage is used, prior to the start of the test run, the storage tank destratification pump, shown in Figure 1, shall be operated until the total volume pumped exceeds 1.5 times the tank volume and the difference between the temperature at the top and bottom of the storage tank (TS1 and TS2) is less than 1 °F. These two temperatures shall then be recorded to determine the starting average tank temperature. The total volume pumped may be based on the nominal flow rate of the destratification pump (See section 9.6). If the Category III and IV runs are done with storage, it is recognized that during the last hour of the pre-burn cycle the storage tank must be mixed to achieve a uniform starting temperature and cannot receive heat from the boiler/heater during this time. During this time period, the boiler/heater might cycle or VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 go into a steady reduced output mode. (Note—this would happen, for example, in a Category IV run if the actual maximum output of the boiler/heater exceed the manufacturer’s rated output.) A second storage tank may be used temporarily to enable the boiler/heater to operate during this last hour of the pre-burn period as it will during the test period. The temperature of this second storage tank is not used in the calculations but the return water to the boiler/heater (after mixing device if used) must be 125 °F or greater. 12.4.2 Startup Procedure for Category I and II Test Runs, ‘‘Cold-to-Cold.’’ 12.4.2.1 Initial Temperatures. This test shall be started with both the boiler/heater and the storage at a minimum temperature of 125°F. The boiler/heater maximum temperature at the start of this test shall be 135 °F. The boiler/heater and storage may be heated through a pre-burn or it may be heated by external means. 12.4.2.2 Firebox Condition at Test Start. Prior to the start of this test remove all ash and charcoal from the combustion chamber(s). The loading of the test fuel and kindling should follow the manufacturer’s recommendations, subject to the following constraints: Up to 10 percent kindling and paper may be used which is in addition to the fuel load. Further, up to 10 percent of the fuel load (i.e., included in the 10 lb/ft3) may be smaller than the main fuel. This startup fuel shall still be larger than 2 inches. 12.4.2.3 Storage. The Category I and II test runs shall be done with thermal storage. The initial temperature of the storage must be 125 °F or greater at the start of the test. The storage may be heated during the pre-test burn cycle or it may be heated by external means. Prior to the start of the test run, the storage tank destratification pump, shown in Figure 1, shall be operated until the total volume pumped exceeds 1.5 times the tank volume and the difference between the temperature at the top and bottom of the storage tank (TS1 and TS2) is less than 1 °F. These two temperatures shall then be recorded to determine the starting average tank temperature. The total volume pumped may be based on the nominal flow rate of the destratification pump (See section 9.6). 12.5 Test Runs. For all test runs, the return water temperature to the hydronic heater must be equal to or greater than 120 °F (this is lower than the initial tank temperature to allow for any pipeline losses). Where the storage system is used, flow of water from the boiler/heater shall be divided between the storage tank and the heat exchanger such that the temperature change of the circulating water across the heat exchanger shall be 30 ±5 °F, averaged over the entire test run. This is typically adjusted using the system valves. Complete a test run in each heat output rate category, as follows: 12.5.1 Test Run Start. For Category III and IV runs: Once the appliance is operating normally and the pretest coal bed weight has reached the target value per section 12.4.1, tare the scale and load the full test charge into the appliance. Time for loading shall not exceed 5 minutes. The actual weight of the test fuel charge shall be measured and PO 00000 Frm 00071 Fmt 4701 Sfmt 4700 13741 recorded within 30 minutes prior to loading. Start all sampling systems. For Category I and II runs: Once the appliance has reached the starting temperature, tare the scale and load the full test charge, including kindling into the appliance. The actual weight of the test fuel charge shall be measured and recorded within 30 minutes prior to loading. Light the fire following the manufacturer’s written normal startup procedure. Start all sampling systems. 12.5.1.1 Record all water temperatures, differential water temperatures and water flow rates at time intervals of one minute or less. 12.5.1.2 Record particulate emissions data per the requirements of EPA Method 28WHH and the standards referenced therein. 12.5.1.3 Record data needed to determine overall efficiency (SLM) per the requirements of CSA B415.1–10 (IBR, see § 60.17) clauses 6.2.1, 6.2.2, 6.3, 8.5.7, 10.4.3(a), 10.4.3(f), and 13.7.9.3 12.5.1.3.1 Measure and record the test room air temperature in accordance with the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 6.2.1, 8.5.7 and 10.4.3(g). 12.5.1.3.2 Measure and record the flue gas temperature in accordance with the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 6.2.2, 8.5.7 and 10.4.3(f). 12.5.1.3.3 Determine and record the carbon monoxide (CO) and carbon dioxide (CO2) concentrations in the flue gas in accordance with CSA B415.1–10 (IBR, see § 60.17), clauses 6.3, 8.5.7 and 10.4.3(i) and (j). 12.5.1.3.4 Measure and record the test fuel weight per the requirements of CSA B415.1–10 (IBR, see § 60.17), clauses 8.5.7 and 10.4.3(h). 12.5.1.3.5 Record the test run time per the requirements of CSA B415.1–10 (IBR, see § 60.17), clause 10.4.3(a). 12.5.1.3.6 Record and document all settings and adjustments, if any, made to the boiler/heater as recommended/required by manufacturer’s instruction manual for different combustion conditions or heat loads. These may include temperature setpoints, under and over-fire air adjustment, or other adjustments that could be made by an operator to optimize or alter combustion. All such settings shall be included in the report for each test run. 12.5.1.4 Monitor the average heat output rate on the load side of the heat exchanger based on water temperatures and flow. If the heat output rate over a 10 minute averaging period gets close to the upper or lower limit of the target range (±5 percent), adjust the water flow through the heat exchanger to compensate. Make changes as infrequently as possible while maintaining the target heat output rate. The first test run shall be conducted at the Category IV heat output rate to validate that the appliance is capable of producing the manufacturer’s rated heat output capacity. 12.5.2 Test Fuel Charge Adjustment. It is acceptable to adjust the test fuel charge (i.e., reposition) once during a test run if more than 60 percent of the initial test fuel charge weight has been consumed and more than 10 E:\FR\FM\16MRR2.SGM 16MRR2 mstockstill on DSK4VPTVN1PROD with RULES2 13742 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations minutes have elapsed without a measurable (1 lb or 0.5 kg) weight change while the operating control is in the demand mode. The time used to make this adjustment shall be less than 60 seconds. 12.5.3 Test Run Completion. For the Category III and IV, ‘‘hot-to-hot’’ test runs, the test run is completed when the remaining weight of the test fuel charge is 0.0 lb (0.0 kg). (WFuelBurned = Wfuel) End the test run when the scale has indicated a test fuel charge weight of 0.0 lb (0.0 kg) or less for 30 seconds. For the Category I and II ‘‘cold-to-cold’’ test runs, the test run is completed; and the end of a test is defined at the first occurrence of any one of the following: (a) The remaining weight of the test fuel charge is less than 1 percent of the total test fuel weight (WFuelBurned > 0.99 · Wfuel); (b) The automatic control system on the boiler/heater switches to an off mode. In this case, the boiler/heater fan (if used) is typically stopped and all air flow dampers are closed by the control system. Note that this off mode cannot be an ‘‘overheat’’ or emergency shutdown which typically requires a manual reset; or (c) If the boiler/heater does not have an automatic off mode: After 90 percent of the fuel load has been consumed and the scale has indicated a rate of change of the test fuel charge of less than 1.0 lb/hr for a period of 10 minutes or longer. Note—this is not considered ‘‘stopped fuel combustion,’’ See section 12.5.6.1. 12.5.3.1 At the end of the test run, stop the particulate sampling train and overall efficiency (SLM) measurements, and record the run time, and all final measurement values. 12.5.3.2 At the end of the test run, continue to operate the storage tank destratification pump until the total volume pumped exceeds 1.5 times the tank volume. The maximum average of the top and bottom temperatures measured after this time may be taken as the average tank temperature at the end of the tests (TFSavg, See section 13.1). The total volume pumped may be based on the nominal flow rate of the destratification pump (See section 9.6). 12.5.3.3 For the Category I and II test runs, there is a need to determine the energy content of the unburned fuel remaining in the chamber if the remaining mass in the chamber is greater than 1 percent of the test fuel weight. Following the completion of the test, as soon as safely practical, this remaining fuel is removed from the chamber, separated from the remaining ash and weighed. This separation could be implemented with a slotted ‘‘scoop’’ or similar tool. A 1⁄4 inch opening size in the separation tool shall be used to separate the ash and charcoal. This separated char is assigned a heating value of 12,500 Btu/lb. 12.5.4 Heat Output Capacity Validation. The first test run must produce a heat output rate that is within 10 percent of the manufacturer’s rated heat output capacity (Category IV) throughout the test run and an average heat output rate within 5 percent of the manufacturer’s rated heat output capacity. If the appliance is not capable of producing a heat output within these limits, VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 the manufacturer’s rated heat output capacity is considered not validated and testing is to be terminated. In such cases, the tests may be restarted using a lower heat output capacity if requested by the manufacturer. Alternatively, during the Category IV run, if the rated output cannot be maintained for a 15 minute interval, the manufacturer may elect to reduce the rated output to match the test and complete the Category IV run on this basis. The target outputs for Categories I, II, and III shall then be recalculated based on this change in rated output capacity. 12.5.5 Additional Test Runs. Using the manufacturer’s rated heat output capacity as a basis, conduct a test for additional heat output categories as specified in section 4.3. It is not required to run these tests in any particular order. 12.5.6 Alternative Heat Output Rate for Category I. If an appliance cannot be operated in the Category I heat output range due to stopped combustion, two test runs shall be conducted at heat output rates within Category II. When this is the case, the weightings for the weighted averages indicated in section 14.1.15 shall be the average of the Category I and II weighting’s and shall be applied to both Category II results. Appliances that are not capable of operation within Category II (<25 percent of maximum) cannot be evaluated by this test method. 12.5.6.1 Stopped Fuel Combustion. Evidence that an appliance cannot be operated at a Category I heat output rate due to stopped fuel combustion shall include documentation of two or more attempts to operate the appliance in heat output rate Category I and fuel combustion has stopped prior to complete consumption of the test fuel charge. Stopped fuel combustion is evidenced when an elapsed time of 60 minutes or more has occurred without a measurable (1 lb or 0.5 kg) weight change in the test fuel charge while the appliance operating control is in the demand mode. Report the evidence and the reasoning used to determine that a test in heat output rate Category I cannot be achieved. For example, two unsuccessful attempts to operate at an output rate of 10 percent of the rated output capacity are not sufficient evidence that heat output rate Category I cannot be achieved. 12.5.7 Appliance Overheating. Appliances with their associated thermal storage shall be capable of operating in all heat output categories without overheating to be rated by this test method. Appliance overheating occurs when the rate of heat withdrawal from the appliance is lower than the rate of heat production when the unit control is in the idle mode. This condition results in the water in the appliance continuing to increase in temperature well above the upper limit setting of the operating control. Evidence of overheating includes: 1 hour or more of appliance water temperature increase above the upper temperature setpoint of the operating control, exceeding the temperature limit of a safety control device (independent from the operating control— typically requires manual reset), boiling water in a non-pressurized system or activation of a pressure or temperature relief valve in a pressurized system. PO 00000 Frm 00072 Fmt 4701 Sfmt 4700 12.5.8 Option to Eliminate Tests in Category II and III. Following successful completion of a test run in Category I, the manufacturer may eliminate the Category II and III tests. For the purpose of calculating the annual averages for particulates and efficiency, the values obtained in the Category I run shall be assumed to apply also to Category II and Category III. It is envisioned that this option would be applicable to systems which have sufficient thermal storage such that the fuel load in the Category I test can be completely consumed without the system reaching its upper operating temperature limit. In this case, the boiler/heater would likely be operating at maximum thermal output during the entire test and this output rate may be higher than the manufacturer’s rated heat output capacity. The Category II and III runs would then be the same as the Category I run. It may be assumed that the particulate emission values and efficiency values determined in the startup, steady-state, and end phases of Category I are applicable in Categories II and III, for the purpose of determining the annual averages in lb/mmBtu and g/MJ (See section 13). For the annual average in g/hr, the length of time for stored heat to be drawn from thermal storage shall be determined for the test load requirements of the respective category. 12.5.9 Modification to Measurement Procedure in EPA Method 28WHH to Determine Emissions Separately During the Startup, Steady-State and End Phases. With one of the two particulate sampling trains used, filter changes shall be made at the end of the startup phase and the steady-state phase (See section 3.0). This shall be done to determine the particulate emission rate and particulate emission index for the startup, steady-state, and end phases individually. For this one train, the particulates measured during each of these three phases shall be added together to also determine the particulate emissions for the whole run. 12.5.10 Modification to Measurement Procedure in EPA Method 28WHH and the Standards Referenced therein on Averaging Period for Determination of Efficiency by the Stack Loss Method. The methods currently defined in Method 28WHH allow averaging over 10-minute time periods for flue gas temperature, flue gas CO2, and flue gas CO for the determination of the efficiency with the stack loss method. However, under some cycling conditions the ‘‘on’’ period may be short relative to this 10-minute period. For this reason, during cycling operation the averaging period for these parameters may not be longer than the burner on period divided by 10. The averaging period need not be shorter than one minute. During the off period, under cycling operation, averaging periods as specified in EPA Method 28WHH and the standards referenced therein, may be used. Where short averaging times are used, however, the averaging period for fuel consumption may still be at 10 minutes. This average wood consumption rate shall be applied to all of the smaller time intervals included. 12.6 Additional Test Runs. The testing laboratory may conduct more than one test run in each of the heat output categories E:\FR\FM\16MRR2.SGM 16MRR2 Federal Register / Vol. 80, No. 50 / Monday, March 16, 2015 / Rules and Regulations specified in section 4.3. If more than one test run is conducted at a specified heat output rate, the results from at least two-thirds of the test runs in that heat output rate category shall be used in calculating the weighted average emission rate. The measurement data and results of all test runs shall be reported regardless of which values are used in calculating the weighted average emission rate. 13.0 Calculation of Results 13.1 Nomenclature COs—Carbon monoxide measured in the dilution tunnel at arbitrary time in ppm dry basis.

For determination of the average overall thermal efficiency (hSLM) for the test run, use the data collected over the full test run and the calculations in accordance with CSA B415.1–10 (IBR, see § 60.17), clause 13.7 except for 13.7.2(e), (f), (g), and (h), use the following average fuel properties for oak: %C = 50.0, %H = 6.6, %O = 43.2, %Ash = 0.2. 13.6.5.1 Whenever the CSA B415.1–10 (IBR, see § 60.17) overall efficiency is found to be lower than the overall efficiency based on load side measurements, as determined by Eq. 22 of this method, section 14.1.7 of the test report must include a discussion of the reasons for this result. For a test where the CSA B415.1–10 overall efficiency SLM is less than 2 percentage points lower than the overall efficiency based on load side measurements, the efficiency based on load side measurements shall be considered invalid. [Note on the rationale for the 2 percentage points limit. The SLM method does not include boiler/heater jacket losses and, for this reason, should provide an efficiency which is actually higher than the efficiency based on the energy input and output measurements or ‘‘delivered efficiency.’’ A delivered efficiency that is higher than the efficiency based on the SLM could be considered suspect. A delivered efficiency greater than 2 percentage points higher than the efficiency based on the SLM, then, clearly indicates a measurement error.] 13.6.6 Carbon Monoxide Emissions For each minute of the test period, the carbon monoxide emission rate shall be calculated as: Total CO emissions for each of the three test periods (CO_1, CO_2, CO_3) shall be calculated as the sum of the emission rates for each of the 1-minute intervals. Total CO emission for the test run, COT, shall be calculated as the sum of CO_1, CO_2, and CO_3. 13.7 Weighted Average Emissions and Efficiency. 13.7.1 Determine the weighted average emission rate and delivered efficiency from the individual tests in the specified heat output categories. The weighting factors (Fi) are derived from an analysis of ASHRAE bin data which provides details of normal building heating requirements in terms of percent of design capacity and time in a particular capacity range—or ‘‘bin’’—over the course of a heating season.

A non-functioning combustor will result in a loss of heating efficiency, and an increase in creosote and emissions. Following is a list of items that should be checked on a periodic basis: • Combustors should be visually inspected at least three times during the heating season to determine if physical degradation has occurred. Actual removal of the combustor is not recommended unless more detailed inspection is warranted because of decreased performance. If any of these conditions exists, refer to Catalyst Troubleshooting section of this owner’s manual. • This catalytic (or hybrid) heater is equipped with a temperature probe to monitor catalyst operation. Properly functioning combustors typically maintain temperatures in excess of 500 °F, and often reach temperatures in excess of 1,000 °F. If catalyst temperatures are not in excess of 500 °F, refer to Catalyst Troubleshooting section of this owner’s manual. • You can get an indication of whether the catalyst is working by comparing the amount of smoke leaving the chimney when the smoke is going through the combustor and catalyst light-off has been achieved, to the amount of smoke leaving the chimney when the smoke is not routed through the combustor (bypass mode). Step 1—Light stove in accordance with instructions in section 3.3.5. Step 2—With smoke routed through the catalyst, go outside and observe the emissions leaving the chimney. Step 3—Engage the bypass mechanism and again observe the emissions leaving the chimney. Significantly more smoke will be seen when the exhaust is not routed through the combustor (bypass mode).’’ 2.3.7 Catalyst Troubleshooting The owner’s manual must provide clear descriptions of symptoms and remedies to common combustor problems and importance. It is recommended that photographs of catalyst peeling, plugging, thermal cracking, mechanical cracking, and masking be included in the manual to aid the consumer in identifying problems and to provide direction for corrective action. 2.3.8 Catalyst Replacement The owner’s manual must provide clear step-by-step instructions on how to remove and replace the catalytic combustor.

Owner’s manual must include: (a) Recommendations about building and maintaining a fire, especially for cold starts and the effectiveness of the top-down approach for starting fires; (b) Instruction on proper use of air controls, including how to establish good combustion and how to ensure good combustion at the lowest burn rate for which the heater is warranted; (c) Ash removal and disposal; (d) Instruction replacement of gaskets, air tubes and other parts that are critical to the emissions performance of the unit, and other maintenance and repair instructions; (e) Warning against overfiring; and (f) Suggested monitoring and inspection techniques and importance of ensuring heater is operating properly, including ensuring visible emissions are minimized. 2.3.9.1 No example text is supplied for 2.3.9(a), (b), (d) and (f) of this appendix since these items are model specific. Manufacturers should provide detailed instructions on building and maintaining a fire including selection of fuel pieces, fuel quantity and stacking arrangement. Manufacturers should also provide instruction on proper air settings (both primary and secondary) for attaining minimum and maximum heat outputs and any special instructions for operating thermostatic controls. Step-by-step instructions on inspection and replacement of gaskets should also be included. Manufacturers should provide diagrams and/ or photographs to assist the consumer. Gasket type and size should be specified. Exhibit 7—Example Text for Item 2.3.9(c) of this appendix: ‘‘Whenever ashes get 3 to 4 inches deep in your firebox or ash pan, and when the fire has burned down and cooled, remove excess ashes. Leave an ash bed approximately 1 inch VerDate Sep<11>2014 16:32 Mar 13, 2015 Jkt 235001 deep on the firebox bottom to help maintain a hot charcoal bed.’’ ‘‘Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, away from all combustible materials, pending final disposal. The ashes should be retained in the closed container until all cinders have thoroughly cooled.’’ Exhibit 8—Example Text covering Item 2.3.9(e) of this appendix: ‘‘DO NOT OVERFIRE THIS HEATER’’ ‘‘Attempts to achieve heat output rates that exceed heater design specifications can result in permanent damage to the heater and to the catalytic combustor if so equipped.’’ 2.3.10 Wood Heater Installation, Including Stack Height, Heater Locations and Achieving Proper Draft Owner’s manual must include: (a) Importance of proper draft; (b) Conditions indicating inadequate draft; (c) Conditions indicating excessive draft; and (d) Guidance on proper stack height and proper heater locations, i.e., not too close to neighbors or in valleys that would cause unhealthy air quality or nuisance conditions. 2.3.10.1 No example text is supplied for (d) because state, local and tribal requirements are model and location specific. Exhibit 9—Example Text for Item (a): ‘‘Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too much draft may cause excessive temperatures in the appliance and may damage the catalytic combustor.

Standards of Performance for New Residential Wood Heaters, New

AGENCY: Environmental Protection Agency.

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final
action to revise the Standards of Performance for New Residential Wood
Heaters and to add a new subpart: Standards of Performance for New
Residential Hydronic Heaters and Forced-Air Furnaces. Today's rule is
authorized by section 111(b) and section 114 of the Clean Air Act
(CAA). The EPA is not finalizing, at this time, the proposed Standards
of Performance for New Residential Masonry Heaters in order to allow
additional time for the Masonry Heater Association to finish their
efforts to develop revised test methods, an emissions calculation
program and an alternative dimensioning standard. This final rule
achieves several objectives for new residential wood heaters, including
applying updated emission limits that reflect the current best systems
of emission reduction; eliminating exemptions over a broad suite of
residential wood combustion devices; strengthening test methods as
appropriate; and streamlining the certification process. Residential
wood smoke emissions are a significant national air pollution problem
and human health issue. These emissions occur in many neighborhoods
across the country, including minority and low-income neighborhoods,
and impact people in their homes. To the extent that children and other
sensitive populations are particularly susceptible to asthma, and that
minority populations and low-income populations are more vulnerable,
this rule will significantly reduce the pollutants that adversely
affect their health. On an economic basis, the public benefits of this
rule vastly outweigh the costs, with every dollar in additional cost
producing more than $100 in public benefit. This final action does not
include any requirements for heaters solely fired by gas, oil or coal.
In addition, it does not include any new requirements associated with
appliances that are already in use. The EPA continues to strongly
encourage state, local, tribal, industry and consumer efforts to change
out (replace) older heaters with newer, cleaner, more efficient
heaters. Additional information is on the EPA Burn Wise Web site at
www.epa.gov/burnwise. Also, we encourage state, local, and tribal
authorities to develop site-specific installation and operating
requirements to help ensure healthy air for all.

DATES: This final action is effective on May 15, 2015. The
incorporation by reference of certain publications listed in this rule
is approved by the Director of the Federal Register as of May 15, 2015.

ADDRESSES: The EPA has established a docket for this action under

A. Executive Summary

The purpose of this action is to finalize amendments to the
Standards of Performance for New Residential Wood Heaters (40 CFR part
60, subpart AAA) and to add one new subpart: Standards of Performance
for New Residential Hydronic Heatersand Forced-Air Furnaces (40 CFR
part 60, subpart QQQQ). This final action was developed following a CAA
section 111(b)(1)(B) review of the 1988 promulgated subpart AAA (53 FR
5860, February 26, 1988), i.e., the 1988 New Source Performance
Standards (NSPS). Section 111 requires the EPA to establish standards
based on best systems of emission reduction (BSER). Section 111(b)
requires emission standards for affected sources and section
111(h)(2)(B) allows the EPA to establish work practices and operational
standards or combinations of standards in certain cases, such as when
testing is impractical due to technological or economic limitations.
The current body of evidence strongly supports revision of the 1988
NSPS to capture the technology improvements and enhanced performance of
such units since 1988 and to expand the applicability of these
standards to include additional wood-burning residential heating
devices that are available today. Section 111 requires the EPA to
consider costs and economic impacts. The potential impact on this
industry that is comprised of over 90 percent small businesses was a
concern to the EPA, and we have minimized these potential impacts to
the degree possible while still achieving significant emission
reductions. For example, we have incorporated stepped (phased) emission
limits and streamlined certification procedures to ease the transition.
The health benefits associated with these regulations are substantially
greater than the cost to manufacture cleaner, lower-emitting
appliances. In fact, the public health benefits of this rule outweigh
the costs by more than 100 times.
As discussed in the preamble to the February 3, 2014, proposed
rule, particulate pollution from wood heaters is a significant national
air pollution problem and human health issue. Residential wood smoke
contains fine particles with an aerodynamic diameter of 2.5 micrometers
or less (PM2.5), carbon monoxide (CO), volatile organic
compounds (VOC), toxic air pollutants (e.g., benzene and formaldehyde),
and climate-forcing emissions (e.g., methane and black carbon).
Residential wood smoke can contribute to unhealthy levels of
PM2.5 in many neighborhoods nationwide, including in
minority and low-income neighborhoods, and impact people in their
homes. To the extent that children and other sensitive populations are
particularly susceptible to asthma, and that minority populations and
low-income populations are more vulnerable to the effects of air
pollution, this rule will significantly reduce the pollutants that
adversely affect their health.
Populations that are at greater risk for experiencing health
effects related to fine particle exposures include older adults,
children and individuals with pre-existing heart or lung disease. Each
year, smoke from wood heaters produces hundreds of thousands of tons of
fine particles throughout the country--mostly during the winter months.
Nationally, residential wood combustion accounts for 44 percent of
total stationary and mobile polycyclic organic matter (POM) emissions,
which account for nearly 25 percent of all area source air toxics
cancer risks and 15 percent of noncancer respiratory effects.\1\
Residential wood smoke causes many counties in the U.S. to either
exceed the EPA's health-based national ambient air quality standards
(NAAQS) for fine particles or places them on the cusp of exceeding
those standards.\2\ To the degree that older, higher emitting, less
efficient wood heaters are replaced by newer heaters that meet the
requirements of this rule, these requirements for cleaner new stoves
will result in substantial reductions in emissions, and thus in
exposure, producing reduced health impacts. A summary of the estimated
health

[[Page 13674]]

benefits is shown in Table 1 below. More details are in the final
Regulatory Impact Analysis (RIA) in the docket for this rule.

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

Consistent with Executive Order 13563, ``Improving Regulation and
Regulatory Review,'' we have estimated the cost and benefits of the
final rule. The estimated annual net benefits at a 3-percent discount
rate are $3.4 billion to $7.6 billion, and $3.1 billion to $6.9 billion
at a 7-percent discount rate in 2013 dollars. The net benefits estimate
reflects 8,269 tons of PM2.5 emission reductions per year,
and a total annualized cost of $45.7 million, producing an unusually
large net benefit for this rule of more than 100 times the costs, and
even greater net benefits coming from the new rule applied to single
burn rate stoves. We estimate that this rule will result in 360
(Krewski, et. al., 2009) or 810 (Lepeule, et. al., 2012) avoided
premature deaths per year. The non-monetized benefits include 46,000
tons of CO reductions per year; 9,300 tons of VOC reductions per year;
reduced exposure to hazardous air pollutants (HAP), including
formaldehyde, benzene, and polycyclic organic matter (POM); reduced
climate effects due to reduced black carbon emissions and reduced
greenhouse gases emissions; reduced ecosystem effects; and reduced
visibility impairments. Table 1 is a summary of the results of the
analysis per type of residential wood heater. We have provided
estimates reflecting average annual impacts for the 2015 to 2020
timeframe, which are the implementation years analyzed in the RIA for
this final rule.

\a\ All estimates are for the time frame from 2015 to 2020 inclusive. These results include units anticipated to
come online and the lowest cost disposal assumption. Total annualized costs shown in this table are estimated
at a 7-percent interest rate to be consistent with guidance from the Office of Management and Budget (OMB).
Total annualized costs are also estimated at a 3 percent interest rate for each source category to be
consistent with OMB guidance, and these costs are about 13 percent less than the total annualized costs
presented in this table. These costs are presented in the RIA and in the cost memoranda for this final rule.
The monetized net benefits with total annualized costs at a 3 percent interest rate are minimally different
than those calculated with total annualized costs at a 7 percent interest rate.
\b\ Total monetized benefits are estimated at a 3-percent discount rate. The total monetized benefits reflect
the human health benefits associated with reducing exposure to PM2.5 through reductions of directly emitted
PM2.5. It is important to note that the monetized benefits include many but not all health effects associated
with PM2.5 exposure. Benefits are shown as a range from Krewski et al. (2009) to Lepeule et al. (2012). These
models assume that all fine particles, regardless of their chemical composition, are equally potent in causing
premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effect
estimates by particle type. Because these estimates were generated using benefit-per-ton estimates, we do not
break down the total monetized benefits into specific components.

D. Judicial Review

Under section 307(b)(1) of the Clean Air Act (CAA), judicial review
of these final rules is available only by filing a petition for review
in the United States Court of Appeals for the District of Columbia
Circuit by May 15, 2015. Under section 307(b)(2) of the CAA, the
requirements established by these final rules may not be challenged
separately in any civil or criminal proceedings brought by the EPA to
enforce these requirements. Section 307(d)(7)(B) of the CAA further
provides that ``[o]nly an objection to a rule or procedure which was
raised with reasonable specificity

[[Page 13675]]

during the period for public comment (including any public hearing) may
be raised during judicial review.'' This section also provides a
mechanism for us to convene a proceeding for reconsideration, ``[i]f
the person raising an objection can demonstrate to the EPA that it was
impracticable to raise such objection within [the period for public
comment] or if the grounds for such objection arose after the period
for public comment (but within the time specified for judicial review)
and if such objection is of central relevance to the outcome of the
rule.'' Any person seeking to make such a demonstration to us should
submit a Petition for Reconsideration to the Office of the
Administrator, U.S. EPA, Room 3000, 1200 Pennsylvania Ave. NW.,
Washington, DC 20460, with a copy to both the person(s) listed in the
preceding FOR FURTHER INFORMATION CONTACT section, and the Associate
General Counsel for the Air and Radiation Law Office, Office of General
Counsel (Mail Code 2344A), U.S. EPA, 1200 Pennsylvania Ave. NW.,
Washington, DC 20460.

II. Background Information for This Final Rule

A. What is the NSPS program?

Under section 111 of the CAA, ``Standards of Performance for New
Stationary Sources,'' the EPA lists categories of sources that, in the
EPA's judgment, cause or contribute significantly to air pollution,
which may reasonably be anticipated to endanger public health or
welfare pursuant to section 111(b)(1)(A). Section 111(b)(1)(B) requires
the EPA to promulgate federal standards of performance for new sources
within those categories. At the time the EPA establishes standards for
a source category, the EPA prepares an analysis of the potential costs
and benefits associated with the NSPS, which also includes the benefits
from reductions in pollutants for which the standards do not set
limits. For example, emission reductions associated with the
requirements of this final rule will generate health benefits by
reducing emissions of PM2.5, other criteria pollutants, such
as CO, and non-criteria HAP. In addition, section 111(h) authorizes the
EPA to promulgate design, equipment, work practice, operational, or
combinations of standards to reflect the best systems of continuous
emission reduction. The NSPS established under section 111(b)(1)(B) do
not establish standards of performance for existing sources. However,
numerous states have acted independently of this rule to address new
and existing sources as part of state implementation plan (SIP)
measures necessary to ensure attainment and maintenance of the NAAQS.
The level of control prescribed by section 111 of the CAA is BSER.
In analyzing BSER, the EPA uses available information and considers the
emissions reductions and incremental costs for different systems
available at reasonable cost. The residential wood heaters source
category is different from most NSPS source categories in that it is
for mass-produced residential consumer products. Thus, important
elements in determining BSER include the significant costs and
environmental impacts of delaying production while models with those
systems are designed, tested, field evaluated and certified. Section
111(b)(1)(B) of the CAA requires that the standards be effective upon
the effective date of the NSPS. As noted earlier and discussed more
fully later in this preamble, the stepped (phased) approach for
residential wood stoves/heaters, hydronic heaters and forced-air
furnaces that the EPA is promulgating considers these factors. That is,
for this rulemaking, the EPA has determined the appropriate emission
limits and compliance deadlines that together are representative of
BSER.
Section 111(b)(1)(B) of the CAA requires the EPA to periodically
(every 8 years) review an NSPS unless it determines ``that such review
is not appropriate in light of readily available information on the
efficacy of such standard.'' In making revisions to an NSPS, the EPA
will revise the standards of performance to reflect improvements in
methods for reducing emissions, including consideration of what
emissions limitation is achieved in practice. Numerous stakeholders
have stated that the current body of evidence strongly justifies the
revision of the current residential wood heaters NSPS to capture the
improvements in performance of such units since 1988 and to expand the
applicability of this NSPS to include additional residential wood-
burning heating devices that are available today. Some stakeholders
have suggested that the EPA also develop additional NSPS to regulate
residential heating devices that burn fuels other than or in addition
to wood, e.g., coal, corn or grass. This final rule does not include
any new federal requirements for heaters that solely burn fuels other
than wood. However, the EPA may consider the need for such requirements
during the next review.

B. Why is residential wood smoke a concern?

There is widespread recognition of the health impacts of particle
pollution, to which wood smoke is a contributing factor in many areas.
Wood smoke contains a mixture of fine particles and toxic air
pollutants (e.g., benzene and formaldehyde) that can cause burning
eyes, runny nose, and bronchitis. Exposure to fine particles has been
associated with a range of health effects, including aggravation of
heart or respiratory problems, changes in lung function and increased
respiratory symptoms, as well as premature death. Populations that are
at greater risk for experiencing health effects related to fine
particle exposures include older adults, children and individuals with
pre-existing heart or lung disease. Each year smoke from wood heaters
contributes hundreds of thousands of tons of fine particles throughout
the country--mostly during the winter months. Nationally, residential
wood combustion accounts for 44 percent of total stationary and mobile
polycyclic organic matter (POM) emissions, which accounts for nearly 25
percent of all area source air toxics cancer risks and 15 percent of
noncancer respiratory effects.\3\ Residential wood smoke causes many
counties in the U.S. to either exceed the EPA's health-based NAAQS for
fine particles or places them on the cusp of exceeding those standards.
For example, in places such as Keene, New Hampshire; Sacramento,
California; Tacoma, Washington; and Fairbanks, Alaska; wood combustion
can contribute over 50 percent of daily wintertime fine particle
emissions.\4\ The concerns are heightened because wood stoves, hydronic
heaters, and other heaters are often used around the clock in many
residential areas. To the degree that older, dirtier, less efficient
wood heaters are replaced by newer heaters that meet or exceed the
requirements of this rule, the emissions would be reduced, and thus
exposure as well, and fewer health impacts should occur. The health and
air quality concerns associated with particle pollution and the effects
of wood smoke are discussed in detail in the original listing of
residential wood heaters under section 111(b) in the February 18, 1987,

As discussed in the preamble to the February 3, 2014, proposed
rule, and, in the Executive Summary (section I.A) of this preamble,
particulate pollution from wood heaters is a significant national air
pollution problem and human health issue. To the degree that older,
higher emitting, less efficient wood heaters are replaced by newer
heaters that meet the requirements of this rule, setting these
requirements for cleaner new stoves will result in substantial
reductions in exposure and reduced health impacts.

III. Summary of the Final Rule

A. General

In response to the results of the review of the 1988 NSPS and in
response to comments on the proposed rule and the NODA, the EPA is
amending 40 CFR part 60, subpart AAA, Standards of Performance for New
Residential Wood Heaters, and adding a new subpart QQQQ, Standards of
Performance for New Hydronic Heaters and Forced-Air Furnaces. Subpart
AAA applies to room heaters. This final rule broadens the applicability
of wood heaters subject to the 1988 NSPS beyond adjustable burn rate
wood heaters (the focus of the 1988 regulation) to specifically include
all single burn rate wood heaters/stoves/appliances and pellet heaters/
stoves/appliances and all other residential wood heaters except those
specifically exempt in the rule, e.g., hydronic heaters and forced air
furnaces regulated by subpart QQQQ. (Some pellet heaters/stoves/
appliances were not affected by the 1988 regulation.) This preamble
uses the following terms interchangeably for appliances subject to
subpart AAA: wood heaters, stoves and heaters/stoves/appliances.
Subpart QQQQ applies to two specific types of wood heaters: hydronic
heaters and forced-air furnaces plus any other wood-burning affected
appliance that meets the definition of central heater. This preamble
uses the terms forced-air furnaces and warm-air furnaces
interchangeably for such heaters/furnaces/appliances affected by
subpart QQQQ. Wood heaters, hydronic heaters and forced-air furnaces
manufactured after the effective date of this final rule will be
required to meet PM emission limits.
This final rule does not include any federal emission limitations
that would apply to heaters fueled solely by gas, oil or coal. In
addition, this final rule does not include any new federal requirements
associated with wood heaters or other wood-burning appliances that are
already in use in people's homes. The EPA continues to encourage state,
local, tribal, manufacturer, retailer and consumer efforts to change
out (replace) older heaters with newer, cleaner, more efficient
heaters. Also, we continue to encourage state, local, and tribal
authorities to develop site-specific installation and operating
requirements and oversight to help ensure healthy air for all.
For this final action, the effective date is May 15, 2015 to allow
for Congressional Review under the Congressional Review Act (CRA).
Under the CRA, 5 U.S.C. 801(a)(3), the effective dates of all ``major''
rules are delayed for 60 calendar days after they are submitted to
Congress or after they are published in the Federal Register, whichever
date is later. This final action is a ``major'' rule within the meaning
of the CRA.
Section IV summarizes the changes to the proposed rule reflected in
the final rule, and section V provides a summary of the major comments
received and our responses.
1. Certification Testing and Compliance
As with the 1988 NSPS, because of concern regarding potential
negative impacts on small businesses and potential certification
delays, this revised subpart AAA for wood heaters/stoves and new
subpart QQQQ for hydronic heaters and forced-air furnaces require
manufacturers to participate in a certification program that tests a
representative heater per model line rather than testing every heater.
If the representative heater meets the applicable emission limits
contained in this rule, the entire model line may be certified.
Individual heaters within the model line are still subject to all other
requirements, including labeling and operational requirements.
Manufacturers are required to have quality assurance programs to ensure
that all heaters within the model line conform to the certified design
and meet the applicable emission limits. The EPA will continue to have
the authority to conduct audits to ensure compliance.
Additional requirements apply to entities other than the
manufacturer. Wholesalers and retailers are also subject to the limits
on sales of non-certified affected heaters. Wood heater test
laboratories and certifying entities are subject to quality assurance
and reporting requirements. This final rule for subpart AAA and subpart
QQQQ requires the proper burn practices that have applied to the owner
or operator of a wood heating appliance regulated under subpart AAA
since 1988. In addition, new pellet heater/stove owners and operators
will be required to use only the grades of pellet fuels and wood chips
that are included in the owner's manual based on the heater/stove
certification tests. In this final rule, we are revising the original
1988 enforcement and audit provisions to reflect changes in industry
practices and development of new tools and procedures. We are also
taking final action to improve the previous test methods as well as
adding new test methods. More details are in sections IV.D and V.
2. Stepped Compliance Approach
The 1988 NSPS addressed some of the specific characteristics of
this source category by developing a stepped compliance approach that
provided manufacturers a two-phased implementation of emission limits.
Considering that over 90 percent of the manufacturers and retailers are
small businesses, we have included this approach in the revised subpart
AAA and new subpart QQQQ in order to allow manufacturers lead time to
develop, test, field evaluate and certify current technologies across
their consumer product lines to meet Step 2 emission limits and in most
cases to allow retailers to sell-through inventory. Upon the effective
date of this final rule, all new residential wood heaters subject to
subparts AAA and QQQQ will be required to meet the NSPS standards. The
standards are phased from immediate requirements on the effective date
to Step 2 emission limits five years later. The specific emission
limits and dates for subparts AAA and QQQQ are shown in Table 3 and
Table 4, respectively. To further ease the transition on small
businesses, the EPA will not require new testing of heaters that have
current certificates of compliance under the 1988 NSPS that show they
meet the Step 1 emission levels. Those certificates are automatically
extended beyond their current expiration date until the compliance
deadline for the Step 2 emission limits. Also, this final rule
automatically deems certified hydronic heaters that have been qualified
at the Step 1 emission level (or better) under the EPA voluntary
partnership program for hydronic heaters or forced-air furnaces that
have been independently certified at the Step 1 emission level (or

[[Page 13677]]

better) or under Canadian Standards Association B415.1-10.
3. NSPS Labels
The final rule requires that each room heater under subpart AAA and
central heater under subpart QQQQ be equipped with a permanent label
meeting the applicable requirements in Sec. 60.536 and Sec. 60.5478,
respectively. The permanent label must include identifying information
for the unit and its compliance certification status. The permanent
label must be installed so that it is readily visible both before and
after the unit is installed. This requirement is needed to assist
state, local and tribal officials in determining if a unit complies
with state, local and tribal rules and in determining eligibility for
any future change out (replacement) programs. Note that ``readily
visible'' does not mean under the body of freestanding stove but it
does allow an easily removable decorative fa[ccedil]ade to cover the
label.
In the 1988 NSPS, temporary labels (e.g., hangtags) were required
for wood heaters that are subject to the standards, as well as ones
that are not (e.g., coal heaters/stoves). These temporary labels were
intended to assist consumers in comparing different appliance models
and to inform the consumer about the importance of proper operation and
maintenance. We proposed to remove the requirement for temporary
labels, and we requested comment. After reviewing the comments
received, the EPA now concludes that these temporary labels are most
valuable if they assist purchasers in identifying the cleanest and most
efficient heaters. Therefore, in this final rule the EPA is allowing
(voluntary) a temporary NSPS label (hangtag) for each adjustable burn
rate heater, single-burn rate heater, pellet heater/stove, hydronic
heater and forced-air furnace sold at retail that meets the Step 2
emission limits before the Step 2 compliance date. This temporary label
option will end upon the Step 2 compliance date.
In addition, we are providing an alternative compliance option for
manufacturers who choose to demonstrate compliance with Step 2 emission
limits using cord wood testing rather than the standardized crib wood
testing, currently used for the primary compliance option for
appliances regulated under subpart AAA and for hydronic heaters under
subpart QQQQ. As discussed in the preamble to the February 3, 2014,
proposed rule, crib wood is a specified configuration and quality of
dimensional lumber and spacers that improves the repeatability of the
test method. Cord wood is a different specified configuration and
quality of wood that more closely resembles what a typical homeowner
would use. Cord wood testing is a better measure of how the heaters
will perform on the type of fuel commonly used in homes.
Each of these models would be equipped with both a permanent label
and the voluntary option of a special temporary label (hangtag)
informing consumers that these wood heaters were tested and certified
when burning cord wood. The specific emission limits are discussed in
sections III.B and III.C.
4. New Residential Masonry Heaters (Proposed Subpart RRRR)
The EPA is not taking final action at this time on proposed subpart
RRRR for new residential masonry heaters. Our reason for taking no
action at this time is to allow additional time for the Masonry Heater
Association (MHA) to finish their efforts to develop revised test
methods, an emissions calculation program and an alternative
dimensioning standard. The MHA believes these efforts are critical
because most masonry heaters are custom built on-site and testing each
custom model would be difficult. The nationwide emission impacts of
delaying regulating subpart RRRR are small relative to the impacts of
regulating subparts AAA and QQQQ. Fewer than approximately 1,000
masonry heaters are manufactured each year and a total of less than 10
tons per year of PM2.5 are currently emitted. In comparison,
new wood burning appliances covered by subparts AAA and QQQQ are
estimated to number more than 200,000 (2015) and currently emit more
than 11,000 tons per year of PM2.5.\5\

Heaters. January 2015.
---------------------------------------------------------------------------

B. Room Heaters (Revised Subpart AAA)

1. Applicability
After the effective date, new heaters will be required to meet the
updated standards. The new standards apply not only to adjustable burn
rate wood heaters (the focus of the original regulation), but also to
single burn rate wood heaters/stoves, pellet heaters/stoves, and any
other affected appliance as defined in revised subpart AAA as a ``room
heater.'' Subpart AAA, as amended, does not apply to new residential
hydronic heaters or new residential forced-air furnaces because they
are subject to their own subpart. The revised subpart AAA does not
apply to fireplaces as defined in Subpart AAA. This final rule tightens
the definition for ``cook stoves'' and adds definitions for ``camp
stoves'' and ``traditional Native American bake ovens'' to clarify that
they are not subject to the standard other than appropriate labeling
for cook stoves and camp stoves and no requirements for traditional
Native American bake ovens. Finally, the revised subpart AAA clarifies
that the emission limits apply only to wood-burning devices (i.e., not
to devices that only burn fuels other than wood, e.g., gas, oil or
coal).
2. Automatic EPA Certification for Currently Certified Heaters/Stoves
That Meet the Step 1 Emission Levels
In this final rule we make clear that those heaters/stoves with EPA
certifications under the 1988 NSPS that show compliance with the Step 1
emission levels will be automatically deemed as certified to meet the
Step 1 emission limits under this final rule until the Step 2
compliance date. No separate certification will be required. Over 85
percent of heaters/stoves being sold today already meet the Step 1
emission limit. This automatic certification will avoid unnecessary
economic impacts on those manufacturers (over 90 percent are small
businesses) who can then focus their efforts on developing a full range
of cleaner models that meet Step 2 emission levels. This measure should
also help avoid potential delays at laboratories conducting
certification testing for heaters newly subject to the NSPS.
3. Two-Step Compliance Approach
We are promulgating a two-step compliance approach that will apply
to all new adjustable burn rate wood heaters, single burn rate wood
heaters and pellet heaters/stoves. Under this approach, Step 1 emission
limits for these sources will apply to each source manufactured on or
after the effective date of the final rule or sold at retail on or
after December 31, 2015. The approximately 8-month additional time for
the retail sale requirement will allow retailers to sell their
inventories of heaters that do not comply with the Step 1 emission
limits. Step 2 emission limits for these sources will apply to each
heater manufactured or sold at retail on or after the date 5 years
after the effective date of the final rule. We are not including the
alternative three-step emission limit compliance approach for which we
also requested comment in the proposal. The comments overwhelmingly
indicated that the three-step emission limit approach was inferior not
only environmentally but also economically because it would, in effect,
require

[[Page 13678]]

many small manufacturers to engage in two rounds of research and
development (R&D) rather than one in order to obtain the same eventual
endpoint.
Table 3 summarizes the PM emissions limits that apply to each wood
heater under this two-step approach. Note that the emissions standards
are ``as measured'' by the test methods specified in the rule and are
labeled as PM although the PM is essentially all PM2.5. This
avoids the potential extra testing costs of measuring PM2.5
specifically.

rule.
Step 2: 5 years after the effective date 2.0 g/hr.
of the final rule.
Step 2: Cord wood alternative compliance 2.5 g/hr.
option.
------------------------------------------------------------------------

We are allowing an alternative compliance option for manufacturers
who choose to certify using cord wood (rather than crib wood) to meet
the Step 2 limits. (As discussed earlier in this preamble, crib wood is
a specified configuration and quality of dimensional lumber and spacers
that improves the repeatability of the test method. Cord wood is a
different specified configuration and quality of wood that more closely
resembles what a typical homeowner would use.) Special permanent and
temporary labels for room heaters certified with cord wood would
specify that they meet a PM emissions limit of 2.5 g/hr. The bases for
the crib wood primary emission limit of 2.0 g/hr and the cord wood
alternative compliance option emission level of 2.5 g/hr for wood
stoves, as well as the limited environmental impact of the differences
in these levels, are discussed in section V.A BSER and Particulate
Emission Limits for Room Heaters (revised subpart AAA).
The proposal would have required cord wood testing for all Step 2
compliance certifications. Cord wood testing is a better measure of how
stoves actually perform in home use; however, we are concerned that
many manufacturers (over 90 percent are small businesses) do not yet
have experience with designing their stoves to perform well with cord
wood testing. Some manufacturers may not be ready for cord wood testing
by the Step 2 compliance date and that would result in unreasonable
economic impacts. Allowing the cord wood alternative compliance option
acknowledges the efforts of the industry leaders and encourages others
to follow their example.
The revised subpart AAA does not include a compliance extension for
small volume manufacturers. An extension for manufacture of adjustable
burn rate heaters is not necessary because over 85 percent of these
appliances already comply with Step 1 emission levels.
We are making a single determination of BSER for catalytic,
noncatalytic and hybrid heater systems so as not to restrict open
market competition. As in the 1988 NSPS, we are requiring manufacturers
to provide warranties on the catalysts, prohibit the operation of
catalytic heaters/stoves without a catalyst and require operation
according to the owner's manual. In addition, we are requiring
manufacturers to provide warranties for noncatalytic and hybrid
heaters/stoves and require operation according to the owner's manual.
As discussed at proposal, we considered requiring efficiency
standards (heat output divided by fuel input) to ensure that stoves are
efficient and burn no more wood than necessary for the heat demand so
that the consumers can save money on fuel and so that the emissions are
lower. We did not propose an efficiency standard because we did not
have sufficient data, but the final rule uses our authority under
section 114 to require the manufacturer to submit third-party
efficiency test data, submit the test data report to the EPA and post
the results on the manufacturer's Web site. Also, we will include this
submitted information on the EPA Web site. This will help consumers to
make informed choices to reduce fuel costs and emissions now and
provide data for us to consider for future rulemaking.
4. Emission Testing, Reporting and Certification
We are requiring emission testing, reporting and certification
based on crib wood to demonstrate compliance with Step 1 and Step 2
emissions limits. As discussed in the preamble to the February 3, 2014,
proposed rule, ``crib wood'' is a specified configuration and quality
of dimensional lumber and spacers that improves the repeatability of
the test method. In this final rule, we are also establishing an
alternative compliance option that allows manufacturers to use cord
wood for the certification tests. ``Cord wood'' is a different
specified configuration and quality of wood that more closely resembles
what a typical homeowner would use.
Commenters overwhelmingly agreed that tuning heaters for crib wood
certification tests often results in poorer performance in homes. Based
on the existence of a viable draft cord wood test method and the
expectation at proposal that the ASTM International (formerly known as
American Society of Testing and Materials) test methods for cord wood
would be complete soon after the NSPS proposal and that significant
testing of wood heaters re-tuned to perform well on cord wood would
occur before promulgation of this final rule, the EPA proposed to
require testing only with cord wood for compliance with Step 2
emissions limits. We still encourage manufacturers to design wood
heaters that best represent in-home performance on cord wood that
consumers use as soon as possible. However, the ASTM cord wood test
methods have not been completed and only limited testing using the
draft methods has occurred.
We received numerous comments from noncatalytic stove manufacturers
and laboratories and some states with concerns about when the cord wood
test methods would be ready and how quickly noncatalytic stoves could
be redesigned to perform well with cord wood certification testing that
we proposed for Step 2, i.e., 5 years after the effective date. As
discussed in the NODA, as of May 2014, we had test data for three
catalytic or hybrid wood heaters/stoves that performed very well on
cord wood. However, considering all of the above, we have determined
that we do not have sufficient data at this time to support a
regulatory requirement for cord wood testing.
We expect that many manufacturers will choose the alternative cord
wood compliance testing option so that consumers will have more
opportunities to purchase stoves that are tuned for in-home use. We
will consider alternative cord wood test method requests on a case-by-
case basis until we are convinced that improved test methods have been
sufficiently demonstrated that they can be relied upon for regulatory
purposes. For now, we will be receptive to alternative test method
requests that use the current ASTM draft method. Also, we will be
receptive to other requests that are sufficiently demonstrated, ideally
using the EPA Method 301 validation procedures. Additionally, we expect
that within the next few years we will receive enough cord wood test
data for the EPA to establish revised certification requirements based
on cord wood testing.
The final rule requires that pellets for the certification tests be
only those that

[[Page 13679]]

have been graded under a licensing agreement with a third-party
organization and meet the minimum quality specifications in Sec.
60.532. Commenters indicated that several organizations are currently
available and others are planned, for example, the Pellet Fuels
Institute (PFI), ENplus and CANplus. Details of the PFI program are
available at https://pelletheat.org/pfi-standards/pfi-standards-program/. Details of the ENplus program are at https://www.enplus-pellets.eu/wp-content/uploads/2012/01/ENplus-Handbook-2.0.pdf. Details
of the CANplus program are at https://controlunion.ca/fileupload/CA/Certifications/ENplusCANplus/CANplus_handbook_v2-0.pdf. Manufacturers'
data show that pellet fuel quality assurance is necessary to ensure
that the appliances operate properly and meet the certified emission
limits.
At this time, we lack sufficient data to issue a CO emissions limit
in today's final rule. However, this final rule uses our authority
under section 114 to require manufacturers to determine CO emissions
during the compliance tests (as is typically done already), report
those results to the EPA and include those results on the
manufacturer's Web site, so that data will be available to consumers,
and to the EPA and states for CO NAAQS compliance implementation plan
considerations and future wood heater rulemakings. We intend to include
context and consumer-friendly summaries of the submitted CO emissions
data on the EPA Burn Wise Web site also.
Like the 1988 subpart AAA, this final rule uses the EPA authority
under section 114 of the CAA to require each manufacturer to submit
applications for certifications of compliance for all new models. We
are revising the certification process to include third-party
certifiers in order to reduce the potential for certification delays
that could result from insufficient capacity. However, commenters
expressed concern, which we share, that there may not be sufficient
third-party certifier capacity and review and approval capacity by the
EPA, especially in the first year. Therefore, to avoid unfairly
restricting the production and sales of manufacturers who do all the
things they should do and then potentially have to wait on EPA
approval, we have added a conditional, temporary approval by the EPA
based on the manufacturer's submittal of a complete certification
application. The application must include the full test report by an
EPA-accredited laboratory and all required compliance statements by the
manufacturer. The conditional approval would allow manufacture and
sales for 1 year or until EPA review of the application, whichever is
earlier. Within that year, the manufacturer must submit a certificate
of conformity by a third-party certifier. (In this preamble, we use the
terms ``third-party certifier,'' ``certifying body,'' ``certifying
entity'' and ``certifying body/entity'' interchangeably.)
The EPA is revising the definition of ``Accredited Test
Laboratory,'' from only EPA-accredited laboratories to include
laboratories accredited by a nationally recognized accrediting body/
entity to perform testing for each of the test methods specified in
this NSPS under ISO-IEC \6\ Standard 17025. Laboratories must be
approved by the EPA before beginning certification testing. Current
EPA-accredited laboratories may retain their accreditation until 3
years after the effective date of this final rule. Laboratories that
are not currently EPA-accredited must achieve ISO-accreditation and
register with the EPA within 6 months of the effective date of this
rule. Laboratories must report any changes in their accreditation and
any deficiencies found under ISO 17025 to the EPA, and the EPA may
revoke approval if warranted.
---------------------------------------------------------------------------

\6\ The International Organization for Standardization (ISO) and
the International Electrotechnical Commission (IEC) prepare and
publish international standards.
---------------------------------------------------------------------------

The EPA is requiring a ``Certifying-Body-Based Certification
Process'' beginning 6 months after the effective date of this final
rule for all heaters/stoves except hydronic heaters. For hydronic
heaters, the ``Certifying-Body-Based Certification Process'' is
required upon the effective date of this final rule because this
certification process has already been required under EPA's Hydronic
Heater Partnership Program since October 2008. Under this process for
all heaters/stoves subject to subparts AAA and QQQQ, after testing is
complete, a certification of conformity with the PM emissions limits
must be issued by a certifying body with whom the manufacturer has
entered into contract for certification services. The certifying body
must be accredited under ISO-IEC Standard 17065 and register their
credentials with the EPA and receive EPA approval prior to conducting
any certifications or related work used as a basis for compliance with
this rule and report any changes in their accreditation and any
deficiencies found under ISO 17065. Any certifying body that is
approved by the EPA and is ISO-accredited is required to act in such a
way that will not create a conflict of interest and work with integrity
and honesty. The EPA will oversee the certifying body's work and retain
the right to revoke the EPA approvals if appropriate. Upon review of
the test report and quality control plan submitted by the manufacturer,
the certifying body may certify initial compliance and submit the
required documentation on behalf of the manufacturer to the EPA's
Office of Enforcement and Compliance Assurance for review, approval and
listing of the certified appliance.
The rule continues to require the owner or operator of a wood
heating appliance to operate the heater consistent with the owner's
manual and not burn improper fuel. Owners and operators must operate
pellet fuel appliances with the grades of pellet fuels that are
included in the owner's manual. Manufacturers are required to void
their warranties in cases of improper operation. Numerous states
expressed their support for the continuation of these requirements.
Some states and local jurisdictions have enforced similar requirements,
and this final rule will allow the EPA to approve state requests for
delegation of enforcement authority for these NSPS requirements. In
addition, we expect many state, local and tribal authorities will adopt
some of the important and very successful strategies in Strategies for
Reducing Wood Smoke,\7\ including changing out (replacing) older
heaters with newer, cleaner, more efficient heaters and developing
site-specific installation and operating requirements to ensure heaters
are not over-sized, avoid nuisance conditions, and ensure proper
operation, e.g., using EPA Method 22 observations of visible emissions
as an indicator of potential poor or improper operation to help ensure
healthy air for all.

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

The rule continues to contain the crucial quality assurance
provisions in the 1988 NSPS. For example, manufacturers must request
EPA approval of model line re-certifications or new certifications
whenever any change is made in the original design that could
potentially affect the emissions rate for that model line or when any
of several specified tolerances of key components are changed. The 1988
requirements for manufacturer quality assurance programs are
strengthened in the revised rule by requiring the manufacturer within 6
months after the effective date to

[[Page 13680]]

contract for a certifying-body to conduct quality assurance audits
within 12 months. The certifying body will conduct regular, unannounced
audits to ensure that the manufacturer's quality control plan is
implemented properly.
The EPA audit testing programs of the 1988 NSPS are retained under
the revised rule, although they are streamlined and simplified to
better ensure compliance and to clarify that audits can be based on any
information the EPA has available and that audits do not need to be
statistically random. Also, the rule clarifies that the EPA and states
are allowed to be present during the audits and that states (and other
entities, including the public) may provide the EPA with information
that may ultimately be used in any EPA enforcement and compliance
assurance efforts.

C. Central Heaters: Hydronic Heaters and Forced-Air Furnaces (Subpart
QQQQ)

1. Applicability
After the effective date, new heaters will be required to meet the
new standards. In this final rule, the EPA is adding 40 CFR part 60,
subpart QQQQ, which applies to all new wood-fired residential hydronic
heaters, wood-fired forced-air furnaces and any other wood-fired
affected appliance defined in subpart QQQQ as a ``central heater.''
Wood-fired means designed or marketed to be capable of burning wood or
used to burn wood. For example, a coal-fired heater cannot be marketed
as capable of wood-burning unless it meet the requirements of this
rulemaking and the marketing brochures and owner's manuals must be
clearly specific to coal rather than wood. Hydronic heater means a
fuel-burning device designed to burn wood or wood pellet fuel for the
purpose of heating building space and/or water through the
distribution, typically through pipes, of a fluid heated in the device,
typically water or a water and antifreeze mixture. Forced-air furnace
means a fuel burning device designed to burn wood or wood pellet fuel
that warms spaces other than the space where the furnace is located, by
the distribution of air heated by the furnace through ducts.
This new ``central heater'' categorization better ensures that all
appliances affected under this new subpart are included in this final
action. Adding subpart QQQQ addresses heater appliance types in the
1987 residential wood heater source category listing that were not
regulated by the 1988 NSPS. This new subpart is designed similar to
subpart AAA, i.e., certification testing of a representative unit in a
model line, label requirements, associated quality assurance
requirements and stepped (phased) implementation.
The provisions of subpart QQQQ apply to each affected unit that is
manufactured or sold at retail on or after May 15, 2015.
2. Automatic EPA Certification for Currently Certified or Qualified
Central Heaters That Meet the Step 1 Emission Levels
In this final rule we make clear that those hydronic heaters with
valid EPA Phase 2 qualifications under the voluntary EPA Hydronic
Heater Partnership Agreement of October 12, 2011, or hydronic heaters
certified by the New York State Department of Environmental
Conservation (NYSDEC) that show compliance with the Step 1 emission
limits will be automatically deemed EPA certified to meet the Step 1
emission limits under this final rule until the Step 2 compliance date.
Also, residential pellet hydronic heaters/boilers that have been
qualified under the Renewable Heat New York (RHNY) program will be
automatically deemed EPA certified to meet Step 1. (Note that the RHNY
program requires pellet heating systems to include installation of
thermal storage to maintain high-efficiency and low emissions
performance throughout daily and annual cycles. The minimum size
thermal storage for boilers less than 85,000 BTU/hr is 119 gallons or
2.0 gallons per 1,000 BTU/hr, whichever is less. For boilers greater
than 85,000 BTU/hr, the minimum heat storage is 2.0 gallons per 1,000
BTU/hr.) No separate EPA certification will be required. Similarly,
forced-air furnaces independently certified (i.e., not self-tested)
under Canadian Standards Association (CSA) B415.1-10 as well as forced-
air furnaces certified by the NYSDEC that show compliance with the Step
1 emission limits will be deemed EPA certified to meet the Step 1
emission limits under this final rule until the Step 2 compliance date.
This automatic EPA certification will avoid unnecessary economic
impacts on those manufacturers (over 90 percent are small businesses)
who can then focus their efforts on developing a full range of cleaner
models that meet Step 2 emission levels. This measure should also help
avoid potential delays at laboratories conducting certification testing
for heaters newly subject to the NSPS.
3. Stepped Compliance Approach
We are promulgating a stepped compliance approach that will apply
to all new central heaters.
For hydronic heaters, standards will apply to each hydronic heater
manufactured after May 15, 2015 and each hydronic heater sold after
December 31, 2015. Step 1 p.m. emission limits will apply to each
hydronic heaters manufactured on or after May 15, 2015 or sold at
retail after December 31, 2015. Step 2 p.m. emission limits will apply
to each hydronic heater manufactured or sold at retail on or after May
15, 2020.
For hydronic heaters, we are not promulgating the alternative
three-step emission limit approach for which we requested comment in
the proposal. The comments overwhelmingly indicated that the three-step
emission limit approach was inferior not only environmentally but also
economically because it would, in effect, require many small
manufacturers to engage in two rounds of R&D rather than one in order
to obtain the same eventual endpoint.
For forced-air furnaces, standards will apply to each forced-air
furnace manufactured or sold after May 15, 2015. Work practice and
operational standards will apply to each forced-air furnace
manufactured or sold at retail after May 15, 2015. Step 1 PM emission
limits will apply to small (less than 65,000 BTU/hr heat output)
forced-air furnaces manufactured or sold on or after May 16, 2016. Step
1 PM emission limits will apply to large (65,000 BTU/hr heat output or
larger) forced-air furnaces manufactured or sold on or after May 15,
2017. Step 2 PM emission limits will apply to each forced-air furnace
manufactured or sold at retail on or after May 15, 2020.
For forced-air furnaces, we are not promulgating the alternative
three-step emission limit approach for which we requested comment in
the proposal. The comments overwhelmingly indicated that the three-step
emission limit approach was inferior not only environmentally but also
economically because it would, in effect, require many small
manufacturers to engage in two rounds of R&D rather than one in order
to obtain the same eventual endpoint. However, commenters were very
concerned about the infeasibility of enforcing an emission limits for
forced-air furnaces due to the technical and economic impracticability
of testing and certifying approximately 50 forced-air furnaces in the
60 days between publication of this rule and the effective date. For
example, a typical forced-air

[[Page 13681]]

furnace certification test takes approximately 1 week in the laboratory
after the furnace is shipped to the laboratory and a time is scheduled
to begin testing. Typically, the laboratory takes approximately 3 or 4
weeks to prepare a complete test report for the manufacturer to submit
to the EPA. A reasonable overall estimate is approximately 1.25 months,
not counting potential conflicts with other testing in the
laboratories. Currently, there are only 4 laboratories that can test
forced-air furnaces. We estimate that approximately 12 small forced-air
furnaces and 38 large forced-air furnaces would need to be tested as
soon as possible. If those tests were to be divided equally among the 4
laboratories, it would take a minimum of approximately 4 months to
submit the 12 certification test reports for the small furnaces and an
additional year to submit the 38 certification test reports for the
large furnaces to the EPA, far longer than the 60 days between the
publication date and the effective date. Thus, as noted above, we are
requiring work practice and operational standards on the effective date
as allowed under section 111(h)(2)(B) of the CAA, and requiring Step 1
PM emission limits for small forced-air furnaces 1 year after the
effective date and Step 1 PM emission limits for large forced-air
furnaces 2 years after the effective date. Specifically, the
manufacturers must develop model-specific descriptions of proper
operation and best practices; include them in their owner's manuals;
provide training on them to their distributors; and provide them in
written and video format to purchasers/operators/users of their
heaters. The specific details that must be included in owner's manuals
are in Sec. 60.5474 and Appendix I of this rulemaking.
The following are excerpts of the operational standards required in
this rule that must be included in the owner's manuals. Operators must
not burn unseasoned wood.
The use of properly split, stored and seasoned wood has much lower
PM emission than high-moisture wood, i.e., green wood or wet wood.
Operators must not burn improper fuels such as (1) residential or
commercial garbage; (2) lawn clippings or yard waste; (3) materials
containing rubber, including tires; (4) materials containing plastic;
(5) waste petroleum products, paints or paint thinners, or asphalt
products; (6) materials containing asbestos; (7) construction or
demolition debris; and (8) paper products; cardboard, plywood or
particleboard (Note that best practices do allow the use of fire
starters made from paper, cardboard, saw dust, wax and similar
substances for the purpose of starting a fire in an affected heater);
(9) railroad ties or pressure treated lumber; (10) manure or animal
remains; (11) salt water driftwood or other or other previously salt
water saturated materials; (12) unseasoned wood; and (13) any materials
that are not included in the warranty and owner's manual for the
subject heater or furnace.
The owner's manual and training materials must also educate
operators on the use of proper operating practices, including correct
positioning of bypasses and air dampers during startup, normal
operation and reloading. Proper practices also include checking air
tubes, catalysts (if so equipped), heat exchangers and other critical
parts of the heater to ensure they are working properly and are
maintained as needed. Best burn operational practices are already
highlighted in many manufacturers' owner's manuals, educational
materials from HPBA and Burn Tips on EPA's Burn Wise Web site. Numerous
comments noted that best work practices and proper operation and
maintenance can significantly reduce emissions at reasonable costs.
Thus, considering all of the above, the EPA has determined that these
work practice and operational standards represent the best systems of
emission reduction as required by section 111(h)(1) for the immediate
time frame from the effective date until the Step 1 PM emissions limits
apply. More discussion of comments on stepped compliance and the EPA's
responses are in section V. Summary of Major Comments and Responses.
Table 4 summarizes the PM emissions limits for hydronic heaters and
forced-air furnaces that will apply at each step. Note that the
emissions standards are ``as measured'' by the test methods specified
in the rule and are labeled as PM although the PM is essentially all
PM2.5. This avoids the potential extra testing costs of
measuring PM2.5 specifically.

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

We are allowing an alternative compliance option for manufacturers
who choose to certify using cord wood (rather than crib wood) to meet
the Step 2 limits for hydronic heaters. The proposal would have
required cord wood testing for all Step 2 compliance certifications.
Cord wood testing is a better measure of how stoves actually perform in
home use; however, we are concerned that many manufacturers (over 90
percent are small businesses) do not yet have experience with designing
their stoves to perform well with cord wood testing. Numerous hydronic
heater manufacturers may not be ready by the Step 2 compliance date and
that could result in unreasonable economic impacts. Allowing this
option acknowledges the efforts of the industry leaders and encourages
others to follow their example. Special (required) permanent and
(voluntary) temporary labels for heaters certified with cord wood would
specify that they meet a PM emissions limit of 0.15 lb/mmBtu heat
output. The Step 2 PM emission

[[Page 13682]]

limit for forced-air furnaces matches the hydronic heater alternate
cord wood option emission level of 0.15 lb/mmBtu because CSA B415.1-10
already specifies cord wood for the certification tests. The bases for
the emission levels are discussed in section V.B BSER and Particulate
Emission Limits for Central Heaters (subpart QQQQ).
We are making a single determination of BSER for catalytic,
noncatalytic, hybrid, cord wood and pellet heaters and furnaces in
order to not restrict open market competition. We are requiring
manufacturers to provide warranties on the catalysts, prohibit the
operation of catalytic heaters and furnaces without a catalyst and
require operation according to the owner's manual. In addition, we are
requiring manufacturers to provide warranties for noncatalytic and
hybrid heaters and furnaces and require operation according to the
owner's manual.
As discussed at proposal, we considered requiring efficiency
standards (heat output divided by fuel input) to ensure that heaters
are efficient and burn no more wood than necessary for the heat demand
so that the consumers can save money on fuel and so that the emissions
are lower. We did not propose an efficiency standard because we
concluded we do not yet have sufficient data, but the final rule uses
our section 114 authority to require efficiency testing and reporting
to the EPA. We will include context and summaries of this information
on the EPA Burn Wise Web site. This will help better inform consumers
so they can choose the best-performing heaters now that will also save
them money on fuel costs and also reduce PM emissions by burning less
wood. This will also provide data to states and the EPA as we consider
future wood heater rulemaking.
At this time, we lack sufficient data to issue a CO emissions limit
in today's final rule. However, this rule uses our section 114
authority to require manufacturers to determine CO emissions during the
compliance tests (as typically conducted), report those results to the
EPA and include those results on the manufacturer's Web site. This will
help better inform consumers so they can choose the best-performing
heaters that have less CO emissions and less health concerns for
themselves and their neighbors. This will also provide data to states
and the EPA as we consider future rulemaking. We intend to include
context and summaries of the submitted CO emissions data on the EPA
Burn Wise Web site also.
In this final rule, we are not setting limits on visible emissions,
and we are not prohibiting use in non-heating seasons. However,
operators should note that some state, local and tribal jurisdictions
have limits, prohibitions and other requirements that must be followed.
Like the subpart AAA requirements, the subpart QQQQ requirements
provide additional time for the sale of unsold hydronic heaters
manufactured before the compliance date. This additional sell-through
time does not include forced-air furnaces because EPA has determined
that it is reasonable for forced-air furnace manufacturers to revise
their owner's manuals, training and marketing materials to comply with
the work practice and operational standards by the effective date.
As in subpart AAA, subpart QQQQ includes a list of prohibited fuels
because their use would cause poor combustion or even hazardous
conditions. As in subpart AAA, subpart QQQQ requires that the owner or
operator must operate the hydronic heater or forced-air furnace in a
manner that is consistent with the owner's manual and the rule requires
the manufacturer to discuss the best operating practices in the owner's
manual. For pellet-fueled appliances, operation according to the
owner's manual includes operation only with pellet fuels that are
specified in the owner's manual. As in subpart AAA, manufacturers must
only specify graded and licensed pellets that meet certain minimum
requirements. Data show that pellet quality is important to ensure that
the appliances operate properly such that emissions are within the
appliance certification limits.
The permanent labeling requirements and owner's manual requirements
in subpart QQQQ are similar to the guidelines in the EPA's current
voluntary hydronic heater program with some improvements. Like in
subpart AAA, the temporary labels (hangtags) are voluntary and are only
for models that meet Step 2 levels before the compliance date and these
hangtags end upon the Step 2 compliance date. Subpart QQQQ also has a
cord wood alternative compliance option with a special permanent label
and a voluntary temporary label (hangtag) for models that meet Step 2
using cord wood. The structure of the rest of subpart QQQQ is similar
to the subpart AAA certification and quality assurance process.
4. Emission Testing, Reporting and Certification
The final rule requires that before manufacture and sale at retail,
all affected hydronic heaters and forced-air furnaces subject to
subpart QQQQ must conduct certification compliance testing, submit a
certificate of compliance and receive EPA approval for the Step 1 and
Step 2 PM emission limits by the dates shown in Table 4.
For hydronic heaters, we are requiring emission testing, reporting
and certification based on crib wood to demonstrate compliance with
Step 1 and Step 2 emissions limits. The final rule requires crib wood
emission testing of hydronic heaters by one of the following methods:
EPA Method 28WHH in its entirety or EPA Method 28WHH-PTS (with approved
adjustment for crib wood versus cord wood) or ASTM E2618-13 with
conditions or European National (EN) test method EN 303-5 with
conditions. We note that EPA's current NSPS general provisions provide
that affected sources may request EPA approval of alternative test
methods on a case-by-case basis as appropriate. See 40 CFR 60.8(b).
Commenters overwhelmingly agreed that tuning heaters for crib wood
certification tests often results in poorer performance in homes. Based
on the existence of viable draft cord wood test methods and the
expectation that the ASTM test methods would be final soon after the
NSPS proposal and that significant testing of heaters re-tuned to
perform well on cord wood would occur before promulgation of this final
rule, the EPA proposed to require testing with cord wood for the Step 2
emissions limits. We still encourage manufacturers to design wood
heaters that best represent in-home performance on cord wood that
consumers use as soon as possible. However, the ASTM cord wood test
methods have not been completed and only limited testing using the
draft methods has occurred.
We received numerous comments with concerns about when the cord
wood test methods would be ready and how quickly heaters could be
redesigned to perform well with cord wood certification testing that we
proposed for Step 2, i.e., 5 years after the effective date. At
proposal, we had limited test data for heaters using cord wood.
Considering all of the above, we have determined that we do not have
sufficient data at this time to adequately support a regulatory
requirement for cord wood testing.
We expect that many manufacturers will choose the alternative cord
wood compliance testing option so that consumers will have more
opportunities to purchase stoves that are tuned for in-home use. We
will consider alternative cord wood test method requests on a case-by-
case basis until we are convinced that improved test methods

[[Page 13683]]

have been sufficiently demonstrated that they can be relied upon for
regulatory purposes. For now, we will be receptive to alternative test
methods requests that use the current ASTM draft methods. We will also
be receptive to other alternative test method requests that are
adequately demonstrated, ideally according to the EPA Method 301
validation procedures. Additionally, we expect that within the next few
years we will receive enough cord wood test data for the EPA to
establish revised certification requirements based on cord wood
testing.
In this final rule, the EPA is relying on the cord wood test method
that has been developed by the CSA for forced-air furnaces. The current
version of CSA B415.1-10 was published in March 2010, and it includes
not only the forced-air furnace test method but also Canadian emission
performance specifications for indoor and outdoor central heating
appliances.
In this final rule, we are relying on efficiency test methods that
have been developed by the CSA. The current version of CSA B415.1-10
was published in March 2010.
As discussed earlier in section III.B.4 of this preamble, regarding
the certification process for room heaters (revised subpart AAA), we
are also requiring third-party certifiers for hydronic heaters and
forced-air furnaces so as to reduce the potential for certification
delays that could result from errors in testing. However, for forced-
air furnaces, we are concerned that there may not be sufficient third-
party certifier capacity specific to forced-air furnace testing
according to the CSA B415.1-10 test method and review and approval
capacity by the EPA, especially in the first year. We do not want to
unfairly restrict the production and sales of forced-air furnace
manufacturers who do all the things they should do and then potentially
have to wait on EPA approval. Thus, we have added a conditional,
temporary approval by the EPA for forced-air furnaces based on the
manufacturer's submittal of a complete certification application. The
application must include the full test report by an EPA-approved
laboratory and all required compliance statements by the manufacturer.
The conditional approval would allow forced-air furnace manufacture and
sales for 1 year or until EPA review of the application, whichever is
earlier. Within that year, the manufacturer must submit a certificate
of conformity by a third-party certifier.
The 1-year conditional, temporary approval by the EPA does not
apply to hydronic heaters because they have been required to submit
third-party certifications for the EPA hydronic heater voluntary
partnership program since 2008 and will continue to do so under this
NSPS.

IV. Summary of Significant Changes Following Proposal

This section is a summary of the significant changes from the
proposed rule based on the comments and additional material we received
and have carefully considered. The reasons for these changes and their
potential impacts are in the Response to Comments (RTC) document and
are summarized in section V Summary of Major Comments and Responses.

A. Best Systems of Emission Reduction/Particulate Emission Limits

We received considerable comment on the proposed PM emission limits
that is relevant to our determination of BSER. As explained in more
detail in section V, these final emission limits represent significant
advances in stove technology and substantial reductions in emissions,
both collectively and from individual units.
1. Room Heaters
The EPA is changing the proposed Step 2 PM emissions limit for new
residential room heaters, including catalytic and noncatalytic
adjustable rate wood heaters, single burn rate wood heaters and pellet
heaters/stoves from 1.3 g/hr to 2.0 g/hr using crib wood. Compliance
for room heaters will be determined using the weighted average of burn
rates rather than requiring each individual burn rate to meet the
limit. To reduce potential certification delays and unnecessary costs
for small businesses, we are adding an automatic Step 1 EPA approval
for models with valid EPA certifications under the 1988 NSPS that show
that the models achieve the Step 1 emission levels. Manufacturers may
choose to test using either crib wood or cord wood. If the
manufacturers choose the cord wood alternative compliance option, the
PM emission limit for cord wood is 2.5 g/hr. Although the number is
higher, the cord wood test method is more reflective of fuel that is
used in homes and the data available to the EPA indicate that this PM
emission level is at least as stringent as the 2.0 g/hr primary crib
wood testing emission limit. More details on this are in section V.A
Summary of Major Comments and Responses.
For wood heater/stove certification tests using cord wood, the EPA
is allowing (voluntary) manufacturers to use a special EPA label which
recognizes that cord wood testing more closely reflects actual in-home
use.
2. Central Heaters: Hydronic Heaters and Forced-Air Furnaces
For new residential hydronic heaters, the final rule keeps the
proposed Step 1 weighted average PM emission rate of 0.32 lb/mmBTU heat
output, establishes a Step 1 PM emissions cap of 18 g/hr for any
individual test run and adds automatic Step 1 EPA certification for
hydronic heater models if they are already qualified as meeting the
Phase 2 emissions level of the EPA's voluntary program. The change from
the proposed Step 1 cap of 7.5 g/hr to the final rule Step 1 cap of 18
g/hr was to match the Phase 2 emission levels of the EPA voluntary
program and reduce potential certification delays. To further reduce
potential certification delays and unnecessary costs for small
businesses, we are also adding automatic Step 1 EPA certification for
hydronic heater models certified by NYSDEC that demonstrate the models
achieve the Step 1 levels and RHNY-qualified pellet hydronic heaters.
Similarly, we are adding automatic Step 1 EPA certification for new
forced-air furnaces that are independently certified (i.e., not self-
tested) under CSA B415.1-10 to meet the Step 1 emission level or that
are certified by NYSDEC and meet the Step 1 emission level. For forced-
air furnaces for Step 1, we deleted the 7.5 g/hr particulate emission
limit per individual burn rate because the CSA B415.1-10 certifications
are based on the weighted average, not the g/hr limit, and because the
manufacturers do not have experience with meeting g/hr limits for these
furnaces.
For hydronic heaters, we are changing the proposed Step 2 PM
emissions limit of 0.06 lb/mmBtu heat output to 0.10 lb/mmBtu heat
output for each individual burn rate, tested on crib wood.
Manufacturers may choose to test using either crib wood or cord wood.
If the manufacturer chooses the cord wood alternative compliance
option, the Step 2 PM emission limit for cord wood is 0.15 lb/mmBtu
heat output. Although the number is higher, the cord wood test method
is more reflective of the fuel that is used in homes and the limited
cord wood data available to the EPA indicate that this PM emission
level is at least as stringent as the 0.10 lb/mmBtu heat output crib
wood testing emission limit. For forced-air furnaces, the Step 2 PM
emission level matches the hydronic heater cord wood

[[Page 13684]]

alternative option because forced-air furnaces are certified using CSA
B415.1-10, which already specifies cord wood as the test fuel. Details
on the bases of the emission levels are in section V, Summary of
Responses to Major Comments.
For hydronic heaters and forced-air furnaces tested with cord wood,
the EPA is allowing (voluntary) manufacturers to use special permanent
labels and EPA temporary labels (hangtags) which recognize that cord
wood testing more closely reflects actual operation under in-home-use
conditions.
3. Masonry Heaters
As stated in section III of this preamble, the EPA is not taking
final action on proposed subpart RRRR for new residential masonry
heaters at this time. Comments indicated that the Masonry Heater
Association (MHA) needs more time to finish their efforts to develop
revised test methods, alternative compliance calculation procedures and
dimensioning procedures. The MHA comments stated that the cost of
testing masonry heaters is high and impractical because almost all are
custom-built onsite. After we receive additional information from MHA
and others, we will consider if we should take final action for new
residential masonry heaters in a future rulemaking.
The potential emission impact of this delay is small. Fewer than
1,000 masonry heaters are built each year. Most manufacturers build
fewer than 15 heaters per year. The total nationwide annual emissions
are estimated to be less than 10 tons of PM2.5.

B. Appliance Certification, Laboratory Accreditation and Third-Party
Certification

In section III.D of the preamble to the proposed rule, we described
the proposed approach for a third-party certification program by an
ISO-accredited certifying body and testing by ISO-accredited testing
laboratories. This approach requires manufacturers to use third-party,
independent ISO-accredited and EPA-approved test labs and certifying
entities to demonstrate compliance with a representative appliance for
a model line.
Under the Administrator Approval Process (see Sec. 60.533(c) of
the proposed rule), we proposed a transition period of 1 year from the
effective date of the final rule for test labs to receive ISO
accreditation through an EPA-recognized accreditation body. In this
final rule, we are increasing the transition period for test
laboratories that are currently EPA-accredited from 1 year to 3 years
from the effective date of this final rule (i.e., until May 15, 2018).
This additional time for test laboratory accreditation will reduce
concerns about costs for these small laboratories and potential testing
delays.
We proposed that certifying entities be required to receive ISO
accreditation upon the effective date of the final rule; however,
commenters stated that ISO accreditations can take 6 months. Requiring
use of ISO-accredited certifying bodies/entities on the effective date
of the final rule can be difficult for small manufacturers of wood
stoves/heaters and forced-air furnaces, which previously have not been
required to obtain certifications from ISO-accredited certifying
bodies/entities; therefore, we are allowing a 6-month transition for
models other than hydronic heaters. The 6-month transition period does
not apply to hydronic heaters because the use of ISO-accredited
certifying bodies/entities has been part of the EPA's voluntary
partnership program for hydronic heaters since 2008.

C. Cost and Economic Impacts

Cost and economic impacts of the proposed rule have been revised to
reflect changes to the standards and improved estimates of costs and
emissions for room heaters and central heaters. See section VI of this
preamble for a discussion of these revised impacts, as well as the RIA
and the RTC document for this final rule for more detailed information.

D. Test Methods and Compliance Certification Calculation Procedures

The EPA proposed a number of changes to test methods established
under the 1988 rule to improve their precision and to better reflect
real-world conditions.
1. Burn Rates in Compliance Certification Calculations
For Step 2 emission limits, we proposed to require certification
compliance at the lowest burn rate (Category 1) and the maximum burn
rate (Category 4) rather than the weighted average of the four burn
rates, which was required in the 1988 rule.
Many comments on the proposal and the data in the NODA strongly
supported the proposed compliance determinations per individual burn
rates. Many other comments strongly opposed the proposal. Considering
all of the comments and focusing on the available test data, especially
the EPA wood stove certification test data by burn rate that we
included in the July 1, 2014, NODA, we are requiring certification
calculations based on the weighted average of the four burn rates for
subpart AAA. More detail is presented in section V.A, BSER and
Particulate Emission Limits for Room Heaters (revised subpart AAA), and
section V.F, Test Methods.
For subpart QQQQ, the final rule uses the weighted average with a
cap for each test run for Step 1 (for hydronic heaters), but retains
the proposed requirement for compliance at each burn rate for Step 2
(for both hydronic heaters and forced-air furnaces), given concerns
about the sometimes very large emissions at individual burn rates. The
emission limits reflect the data available. For a more detailed
discussion of these comments and responses, see the RTC document in the
docket for this rule.
2. Cord Wood Test Method
Based on the existence of viable draft cord wood test methods and
the expectation at proposal that the ASTM ``real world'' test methods
for cord wood would be complete soon after the NSPS proposal and that
significant testing of wood heaters re-tuned to perform well on cord
wood would occur before promulgation of this final rule, the EPA
proposed to require testing only with cord wood for compliance with
Step 2 emissions limits. We still encourage manufacturers to design
wood heaters that perform best on cord wood that consumers use.
However, the ASTM cord wood test methods have not been completed and
only limited testing using the draft methods has occurred. We received
numerous comments from noncatalytic stove manufacturers and
laboratories and some states with concerns about when the cord wood
test methods would be ready and how quickly noncatalytic stoves could
be redesigned to perform well with cord wood certification testing that
we proposed for Step 2, i.e., 5 years after the effective date. (We had
test data for three catalytic or hybrid wood heaters/stoves that
performed very well on cord wood at the time of proposal.) However,
considering all of the above, we have determined that we do not have
sufficient data at this time to support a regulatory requirement for
cord wood testing (other than for forced-air furnaces), but rather will
allow an alternative compliance option for cord wood testing. (Note
that forced-air furnace certification tests are conducted according to
CSA B415.1-10 which has specified cord wood as the test fuel since
2010.)
We expect that many manufacturers will choose the alternative cord
wood

[[Page 13685]]

compliance testing option so that consumers will have more
opportunities to purchase stoves that are tuned for use in the ``real
world.'' We will consider alternative cord wood test method requests on
a case-by-case basis until we are convinced that improved test methods
have been sufficiently demonstrated that they can be relied upon for
regulatory purposes. For now, we will be receptive to alternative test
methods requests that use the current ASTM draft methods. Also, we will
be receptive to other alternative test method requests that are
adequately demonstrated, ideally according to the EPA Method 301
validation procedures. Additionally, we expect that within the next few
years we will receive enough cord wood test data for the EPA to
establish revised certification requirements based on cord wood
testing.
See section III of this preamble for the specific alternative
compliance emissions limit options we are allowing under subparts AAA
and QQQQ for manufacturers of heaters who choose to certify compliance
with cord wood instead of crib wood. The bases for the options are
discussed in section V, Summary of Responses to Major Comments.
3. Additional Test Methods
Based on comments and the need to minimize potential testing and
certification delays for Step 1, the final rule includes additional
test methods for hydronic heaters. In addition to the proposed use of
EPA Method 28WHH and EPA Method 28WHH-PTS, the final rule allows
manufacturers to use ASTM E2618-13 and EN303-05 with specified
conditions/adjustments (e.g., burn rate categories to better match EPA
Method 28WHH and use of thermal storage) for determining compliance
with the Step 1 emission limits. As with all NSPS, manufacturers may
request EPA approval of alternative test methods on a case-by-case
basis. See 40 CFR 60.8.

E. Sell-Through of Inventory

Based on numerous comments from small business manufacturers and
small business retailers and some states, we are lengthening the retail
sell-through period for subpart AAA from 6 months from the effective
date of the final rule to December 31, 2015, approximately 8 months
from the expected effective date. That is, no manufacturer,
distributor, wholesaler or retailer may sell or offer to sell new
stoves after December 31, 2015, that do not meet the Step 1 emission
limit. Eight months will better cover the primary selling period after
the rule is final and will affect a very small number of appliances. We
are also providing a retail sell-through period for subpart QQQQ
hydronic heaters to also cover the primary selling period. We are not
allowing a retail sell-through period for forced-air furnaces because
the manufacturers and retailers can quickly revise the owner's manuals
to add best burn practices to comply with the work practice and
operational standards. These sell-through provisions do not affect
resale of used stoves/heaters; such resale is not restricted by this
rule.

F. Appeals and Administrative Hearing Procedures

Based on the public comments and our additional review of the
history of the 1988 rule, we have determined that there is no need to
make the proposed change to a streamlined Petition for Review process.
Therefore, we are retaining the Appeals and Administrative Hearing
Procedures outlined in the 1988 rule.

V. Summary of Responses to Major Comments

Detailed summaries are in the RTC document in the docket.

A. BSER and Particulate Emission Limits for Room Heaters (Revised
Subpart AAA)

We received a full range of comments on the proposed BSER and
emission limits for room heaters and the data in the July 1, 2014,
NODA. Many comments agreed completely with our proposal and that
approximately 10,000 tons/yr of PM2.5 emission reduction is
very important and would lead to significant improvement in public
health protection.
Some comments indicated that bans of wood burning would be more
appropriate. The EPA is not banning wood burning in this rule because
section 111(a)(1) of the CAA requires that the emission standards
reflect the degree of emission limitation achievable by the application
of BSER.
Some comments suggested that we develop less stringent standards
for rural areas than other areas or no standards in rural areas at all.
The EPA is not setting different emission standards for rural areas
because section 111 of the CAA does not provide legal authority for
differentiated standards based on where the devices are used.
1. Stringency of Step 2 Level Using Cord Wood for Room Heaters
Many noncatalytic stove manufacturers and laboratories and some
other manufacturers were concerned especially about the stringency of
the Step 2 level using cord wood 5 years after the effective date. We
considered all comments and focused on those that discussed the
emission data in detail.
Numerous small business manufacturer comments suggested that (1)
current stove designs are focused on burning crib wood well at the
expense of burning ``real world'' cord wood well, and stoves cannot
just be tweaked to burn both well; (2) experience in homes is that some
crib wood-certified stoves smolder if the homeowner does not operate
them at high burn for at least 30 minutes before dampening down to the
low burn rate settings; (3) a cord wood test method more representative
of in-home use should be developed as soon as possible; and (4) a
voluntary option should be used to establish a cord wood database to
determine BSER.
As discussed in the NODA, limited cord wood testing by Brookhaven
National Laboratory (BNL), under contract to the EPA, showed that
repeatability of the cord wood test method results can sometimes be
very good (i.e., within 15 percent). However, the results of the BNL
cord wood tests also showed that emissions from a popular, inexpensive,
current-model noncatalytic stove that was not adjusted by the
manufacturer for burning cord wood instead of crib wood during the
certification test can be much higher than (in several cases, over
twice as high) the crib wood emission test results.
Other comments suggested that we stay with the proposed cord wood
testing requirement and proposed Step 2 emission level that some
heaters can already meet. For example, Washington State Department of
Ecology (WSDOE) stated that (1) the data show that hybrid stoves are
the best technology capable of meeting Step 2, better than noncatalytic
stoves; and (2) the extensive lack of Category 1 burn rate data in the
certification tests indicates a ``serious flaw'' and that EPA needs to
develop test methods more representative of in-home use that include
start-up and the lowest burn rate at which a device may be commonly
operated. We agree with WSDOE that it appears that hybrid stoves may be
the best technology capable of meeting Step 2, better than noncatalytic
stoves; however, we are concerned about setting required emission
levels that may have potential impacts on a large number of small
businesses that may not yet have much experience with that technology,
and we do not want to prematurely restrict their choices. As discussed
in section IV.D, we agree that test methods are needed that better
reflect in-home use and include start-up and the lowest burn

[[Page 13686]]

rate at which a device may be commonly operated.
As discussed earlier in this preamble, based on the data and
comments, we have determined that it is premature to require a cord
wood-based Step 2 emission limit at this time. Rather, we are basing
the Step 2 requirements on crib wood testing and including an
alternative compliance option to encourage manufacturers to certify
with cord wood as soon as possible to provide consumers with better
information regarding in-home use.
In support of the cord wood alternative compliance option, there
are three stove model lines that meet Step 2 using cord wood testing.
As discussed in section IV.D of this preamble, we expect additional
manufacturers will choose the alternative cord wood compliance testing
option so that consumers will have more opportunities to purchase
stoves that are tuned for in-home use. We will consider alternative
cord wood test method requests on a case-by-case basis until we are
convinced that improved test methods have been sufficiently
demonstrated that they can be relied upon for regulatory purposes. For
now, we will be receptive to alternative test method requests that use
the current ASTM draft methods. We will also be receptive to other
alternative test method requests that are adequately demonstrated,
ideally according to EPA Method 301 validation procedures. We expect
that within the next few years we will receive enough cord wood test
data for the EPA to establish revised certification requirements based
on cord wood testing.
Commenters overwhelming agree that cord wood testing is a better
representation of ``real world'' conditions, provides better
information for consumers to choose the cleanest and most efficient
heaters and that the EPA should encourage cord wood testing. Thus, the
final rule includes a cord wood alternative compliance option for Step
2 and special permanent labels and allows (voluntary) temporary EPA
labels (hangtags) for units tested with cord wood. As discussed earlier
in this section, the proposal reasonably anticipated that all
manufacturers would iteratively adjust the combustion air flows,
directions and proportions to better match the change in hydrocarbon
volatilization rate due to the difference in surface-area-to-volume
ratio and spacing for crib wood versus cord wood. The proposal also
reasonably anticipated that manufacturers would have a full complement
of cord wood tested heaters available by Step 2, i.e., 5 years after
the effective date. Some stoves already perform well on cord wood.
However, comments from some small business noncatalytic stove
manufacturers, small business laboratories and some states have
questioned whether most small business manufacturers could comply with
the Step 2 emission limits based on cord wood by that date. As
discussed in the NODA, the cord wood test data submitted to us for
three catalytic or hybrid wood stoves manufactured by two small
businesses show that their EPA-certified wood stoves (when tested using
cord wood and making no design changes to adjust for testing using cord
wood versus crib wood) have similar emissions as their stoves do when
tested using crib wood. The cord wood results show that they can
achieve an emission limit of 1.3 g/hr, as proposed. Several comments
stated that they did not believe these results are representative of
most EPA-certified stoves and that typical cord wood values are likely
to be higher than the 1.3 gr/hr level, as well as the 2.0 g/hr level of
the final crib wood Step 2 emission level or any other crib wood level.
Recognizing that the cord wood alternative compliance option is an
option rather than a requirement, we have set the cord wood Step 2
emission level at 2.5 g/hr as the alternative compliance option for
room heaters for the following reasons:
Test data show that at least three wood stoves meet a
limit of 1.3 g/hr, which (coupled with some commenters' claims that the
test precision is no better than 1.0 g/hr) would suggest an achievable
limit on the order of 2.3 g/hr.
The State of Washington DOE has required catalytic stoves
since 1995 to meet a limit of 2.5 g/hr.
The Step 2 emission level does not take effect until 5
years after the effective date of this final rule.
The cord wood alternative compliance option provides appropriate
opportunities to small manufacturers who have been leaders in
optimizing for cord wood performance and encourages other manufacturers
to follow their example. More discussion is in the RTC document in the
docket for this final rule.
2. Stringency of Step 2 Level Using Crib Wood for Room Heaters
We have set the crib wood Step 2 emission limit at 2.0 g/hr for the
following reasons:
Focusing on the comments that discussed the details of the
crib wood certification test data for Step 2, nearly 90 percent of
current catalytic/hybrid stoves and over 18 percent of current
noncatalytic stoves would meet the Step 2 emission limit of 2.0 g/hr in
the final rule. This compares to 20 percent of catalytic/hybrid wood
heaters/stoves and only 3 percent of noncatalytic wood heaters/stoves
for the proposed 1.3 g/hr Step 2 emission limit.
Considering that current stove sales are approximately 20
percent catalytic/hybrid stoves and 80 percent noncatalytic stoves, the
estimated impact of adjusting the Step 2 emission level from 1.3 g/hr
to 2.0 g/hr will be to decrease the emission reduction estimated for
this rule by approximately 36 tons per year, which is relatively small
compared to the rule's total estimated emission reduction of 8,269 tons
per year. Furthermore, the impact for any individual stove is only on
the order of 2 pounds per year.
The final Step 2 emission limit of 2.0 g/hr is more
stringent than any current state requirement.
Thus, considering the significant emission reductions for this
final rule and the potential significant cost impacts for this industry
that is comprised of over 90 percent small businesses, and considering
that the difference between the proposal and this final rulemaking is
less than approximately 36 tons per year compared to the 8,269 tons per
year for this final rulemaking, we judge that a final Step 2 emission
level of 2.0 g/hr within 5 years as BSER for room heaters is a
reasonable balance of environmental impacts and costs.
3. Determination of BSER for Room Heaters
Some comments questioned that BSER is adequately demonstrated. The
data in the paragraph above show that not only are the emission levels
demonstrated, the percentages of current heaters that already meet Step
2 demonstrate the reasonableness of the Step 2 emission limit,
especially considering that the Step 2 emission limit becomes
applicable 5 years after the effective date.
Some comments recommended that the final rule be as stringent as
the cleanest stoves on the market and some comments suggested numbers
that reflect the top 5 percentile. Section 111 of the CAA does not
specify any particular floor for BSER determinations but does require
consideration of costs. As discussed above, considering that the
emission reduction difference between the proposal and this final
rulemaking is approximately 36 tons per year (compared to the 8,269
tons per year for this final rulemaking), we judge that a final Step 2
BSER of 2.0 g/hr within 5

[[Page 13687]]

years is a reasonable balance of environmental impacts and costs.
Some comments suggested that the precision of the test method is
not good enough to set emission limits more stringent than the 1988
NSPS. In response, we note that the State of Washington DOE has
successfully required a 2.5 g/hr emission limit for catalytic stoves
since 1995, and several stoves have been EPA-certified at 1.0 g/hr,
which is well under the final Step 2 emission limit of 2.0 g/hr. Even
if the commenters' claims were correct that the precision is no better
than 1.0 g/hr, the final emission limit of 2.0 g/hr would still cover
these stoves, i.e., 1.0 g/hr plus 1.0 g/hr equals 2.0 g/hr, the step 2
emission limit. Further, we note that the final rule deletes the
previously required upward adjustment for Method 5G to 5H, which was
sometimes over a 30 percent increase for certification values (under
the 1988 NSPS and the State of Washington DOE) that were tested using
Method 5G.

B. BSER and Particulate Emission Limits for Central Heaters (Subpart
QQQQ)

Comments of many small business manufacturers of hydronic heaters
and forced-air furnaces questioned the demonstrations of BSER for
hydronic heaters and forced-air furnaces, especially the proposed cord
wood Step 2 limit of 0.06 lb/mmBtu. As discussed earlier in sections
III.B and III.C of this preamble, considering the numerous comments
expressing concern about whether most small business manufacturers will
be ready in time, reviewing the data currently available, and
acknowledging that the expected ASTM cord wood test methods are not yet
completed at this time, we have determined that it is premature to
require cord wood certification tests for hydronic heaters at this
time. Rather, we are allowing a cord wood alternative compliance
option.
1. Stringency of Step 1 Level Using Crib Wood for Central Heaters
Focusing on the crib wood test primary requirement and crib wood
test data, we see that there are already 50 hydronic heater models
Phase 2 qualified under the EPA hydronic heater voluntary partnership
program, which also meet the Step 1 emission levels of this final NSPS.
These models will be automatically deemed EPA-certified for Step 1 of
this final NSPS. (There are also 19 voluntary program qualification
tests recently submitted to the EPA that, if valid, will result in 19
additional Phase 2 model qualifications.) Similarly, models certified
by the NYSDEC that comply with Step 1 will also be automatically deemed
EPA certified until Step 2. Also, over 20 pellet heaters/boilers are
already qualified under the RHNY program, and they will be
automatically deemed to be EPA-certified for Step 1 provided they
comply with the RHNY requirements for installation and operation with
adequate thermal storage. That is, no additional certification will be
necessary for these three groups for Step 1.
For forced-air furnaces, commenters indicated that the Step 1 p.m.
emission limit was achievable but small furnaces needed 1 year and
large furnaces needed 2 years to complete the certification testing. As
discussed earlier, the final rule incorporates the necessary additional
time for testing.
2. Stringency of Step 2 Level Using Crib Wood for Central Heaters
For new residential hydronic heaters, we have set the crib wood
Step 2 emission level at 0.10 lb/mmBtu based on the following:
Looking at the crib wood test primary requirement for Step
2 (0.10 lb/mmBtu), 9 of the 50 (18 percent) EPA-qualified hydronic
heater models currently achieve Step 2 on crib wood (per run); and all
20 of the RHNY-qualified models achieve 0.10 lb/mmBtu.
The proposed Step 2 level (0.06 lb/mmBtu) currently is
achieved only by 3 of the 49 (6 percent) EPA-qualified models (per
run).
The emission reduction difference between the proposed
Step 2 hydronic heater emission level (0.06 lb/mmBtu) and the final
Step 2 hydronic heater emission level (0.10 lb/mmBtu) is approximately
only 15 tons per year (compared to the 8,269 tons per year for this
final rulemaking).
Considering the potential significant cost impacts for this
industry that is comprised of over 90 percent small businesses, and
that the relatively small difference in emission reductions between the
proposal and this final rulemaking, we judge that a final hydronic
heater Step 2 emission level of 0.10 lb/mmBtu within 5 years as BSER is
a reasonable balance of environmental impacts and costs.
3. Stringency of Step 2 Level Using Cord Wood for Central Heaters
As with room heaters (subpart AAA) and for the same reasons,
hydronic heaters (subpart QQQQ) have a cord wood alternative compliance
option. Considering that it is an option designed to encourage
leadership for others to follow, that it is an option rather than a
requirement and that many European models already achieve levels better
than 0.06 lb/mmBtu, we have determined that 0.15 lb/mmBtu within 5
years as the cord wood alternative compliance option is a reasonable
balance of environmental impacts and costs. We note that the RHNY
emission qualification requirement is 0.08 lb/mmBtu. Further, we note
that even if there were to be method uncertainty on the order of
approximately four times the expected precision of 35 percent, models
at 0.06 lb/mmBtu would still be included.
We have set the same final Step 2 emission level for forced-air
furnaces as BSER as we have for hydronic heaters based on the
following:
The emission reduction difference between the proposed
forced-air furnace Step 2 emission limit of 0.06 lb/mmBtu and this
final rulemaking (0.15 lb/mmBtu) is approximately 40 tons per year
(compared to 8,269 tons per year emission reduction for this final
rulemaking). The difference is slightly larger for forced-air furnaces
compared to hydronic heaters because the annual sales of forced-air
furnaces are much larger (i.e., 41,000 versus 13,000).
We considered the potential significant cost impacts for
this industry that is comprised of over 90 percent small businesses, as
well as the modest difference between the environmental impacts of the
proposal and this final rulemaking. Therefore, for forced-air furnaces,
we judge that a final Step 2 emission level of 0.15 lb/mmBtu within 5
years as BSER is a reasonable balance of environmental impacts and
costs.
Since forced-air furnaces and indoor hydronic heaters compete in
the same market, wise consumers expect similar performance. We expect
most forced-air furnace manufacturers to transfer technology and
knowledge from wood stoves and hydronic heaters. Some small forced-air
furnaces have already transferred technology from wood heaters to
achieve good performance. Several industry comments questioned their
ability to transfer technology from hydronic heaters because of their
concerns about size limitations in order to install forced-air furnaces
indoors going through doorways and other entrances to basements. They
were especially concerned that the space limitations may affect their
ability to adequately insulate the models that may be installed in
close proximity to combustibles. We acknowledge their concerns but note
that coal, oil and natural gas forced-air furnaces and indoor hydronic
heaters that have similar space limitations and proximity to
combustibles conditions have successfully handled those concerns for
many years. For example, numerous

[[Page 13688]]

cord-wood-fired indoor hydronic heaters have been safely installed
without large volumes of thermal insulation around the firebox

C. Appliance Certification

Many comments stressed the importance of easy public availability
of certification test reports (especially electronically), limited CBI
claims, more details on the EPA Web sites, better labels and more
outreach to encourage change outs to cleaner stoves. We agree with
these comments and the final rule incorporates this transparency and
consumer-friendliness. Some comments suggested wording clarifications
that we have incorporated in the final rule. More details are in the
RTC document included in the docket for this rule.

D. Laboratory Accreditation, Third-Party Certification and
Administrative Approval Process

Many comments stressed the importance of credible data for the
certifications and the value of close EPA oversight, notwithstanding
the addition of ISO-accredited laboratories and ISO-accredited
certifying entities. Some comments suggested that the EPA should allow
the ISO-accredited certifying entities to issue NSPS certificates
directly and that the EPA's role should be solely to review the
certifications and only question their certificates upon cause. The
small business laboratories requested more time for the transition to
ISO-accreditation because of the cost. As discussed earlier in this
preamble, the final rule allows a 3-year extension of current EPA
accreditations of laboratories and allows 6 months for ISO
accreditation of certifying entities, except for hydronic heaters,
which have used ISO-accredited certifying entities since October 2008
for the EPA voluntary program. The EPA will retain its approval and
oversight functions for this final rule. As also discussed earlier in
this preamble, to address the possibility that there may not be
sufficient third-party certifier capacity and review and approval
capacity by the EPA, especially in the first year, and so as to avoid
unfairly restricting the production and sales of manufacturers who do
all the things they should do and then potentially have to wait on the
EPA approval, we have added a conditional, temporary approval by the
EPA for room heaters subject to revised subpart AAA, as well as forced-
air furnaces subject to subpart QQQQ, based on the manufacturer's
submittal of a complete certification application. The application must
include the full test report by an EPA-accredited laboratory and all
required compliance statements by the manufacturer. The conditional
approval would allow manufacture and sales for 1 year or until EPA
review of the application, whichever is earlier. Within 1 year, the
manufacturer must submit a certificate of conformity by a third-party
certifier.
The 1-year conditional, temporary approval by the EPA does not
apply to hydronic heaters because they have used third-party
certifications for the voluntary program since 2008 and will continue
to do so under the NSPS.

E. Costs and Economic Impacts

1. Costs
Comments received on the proposed rule included information and
opinions regarding the EPA wood heater cost estimates.\8\ Comments
ranged from criticism that the EPA overestimated costs to criticism
that the EPA underestimated costs. The comments that provided data and/
or analysis explaining why the commenter thought EPA had not accurately
estimated the costs were most persuasive, and we have revised our cost
estimates based on those detailed comments. Details of our responses to
cost comments are in the RTC document and the technical cost memoranda
in the docket for this final rule.

through https://www.regulations.gov by searching Docket ID EPA-HQ-
OAR-2009-0734.
---------------------------------------------------------------------------

a. Room Heaters
For example, Washington State Department of Ecology stated that the
proposal cost estimates were overestimates and that our estimates did
not address input from Woodstock Soapstone Stoves, winner of the 2013
Wood Stove Decathlon, which estimates that the cost of new product
development is approximately $200,000, and furthermore that the
proposal cost estimates did not address the economies manufacturers
realize when they develop functionally identical models from the
originally certified model.\9\ Some other commenters generally stated
that EPA's breakdown of cost estimates faced by manufacturers is
inaccurately low. We have considered all the comments and have revised
our cost estimates based on comments that provided additional detailed
cost data.

from the Washington State Department of Ecology; available at https://www.regulations.gov/#!documentDetail;D=EPA-HQ-OAR-2009-0734-1397.
---------------------------------------------------------------------------

Prior to proposal, we heard various estimates of the costs to bring
a wood heater from concept to completion, from $200,000 for a single
model to $1,360,000 for a 4-firebox model line. For example, a Hearth
and Home article estimated the total cost to bring a model from
conception to market as $645,000 to $750,000 for steel stoves and over
$1 million for cast-iron, enameled wood stoves. The authors indicated
that costs would decrease for separate models in the same line by up to
25 percent. Based on this information, we estimated that a 4-model
steel line would cost up to $328,125 per model to develop. These costs
include marketing, design, developing first generation, second
generation and prototype units; NSPS and safety testing, equipment
tooling, etc.\10\ Two other manufacturers also provided estimated
development costs for a 4-box model line, and based on that information
at proposal we estimated average costs to develop a new model line,
including testing with both crib wood and cord wood and reporting and
recordkeeping, of $356,250 for certified wood stoves and pellet stoves.
We also estimated $356,250 for single burn rate stoves, forced-air
furnaces and hydronic heaters.

The Hearth Patio and Barbecue Association (HPBA) provided detailed
estimates of adjustable burn rate wood stoves and hydronic heater model
development costs. According to HPBA, the proposal cost estimates are
deficient because they do not reflect specific emission rates or
emission performances. Their detailed wood stove cost estimates are
located in Attachment 2 of the HPBA comments and were prepared by
National Economic Research Associates (NERA) Economic Consulting (May
2014).\11\ Appendix A of the document, Woodstove Cost Modeling

estimates we reviewed and adapted for this analysis.\12\

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

The Ferguson analysis provides cost estimates for four categories
of emission reductions based on the proposed emission levels,
consisting of modifying 7.5 g/hr stoves to comply with a new 4.5 g/hr
emission limit, modifying the 4.5 g/hr stoves to comply with new
emission limits of 2.5 g/hr or 1.3 g/hr stoves, and

[[Page 13689]]

modifying a 2.5 g/hr stove to a new emission limit of 1.3 g/hr. The
resulting cost components consisted of capital costs per model (R&D,
engineering labor, tooling, equipment integration, preliminary testing,
and other costs to design and manufacture the modified wood stove
model) and other fixed costs per model (certification testing and
safety testing, roll-out of the modified products including store
display models and burn programs, brochures, user manuals, training and
product discounts). The mid-point capital costs presented by Ferguson
range from $281,725 to $532,050 depending on the emission reduction
range.\13\

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

As discussed earlier in section III.A, unlike the proposed rule,
the final subpart AAA rule only contains a Step 1 PM emission limit of
4.5 g/hr and a Step 2 PM emission limit of 2.0 g/hr, with no
alternative, three-step emission limits. The comments overwhelmingly
indicated that the three-step emission limit approach was inferior not
only environmentally but also economically because it would, in effect,
require many small manufacturers to engage in two rounds of R&D rather
than one in order to obtain the same eventual endpoint.
The Step 1 cost for 7.5 to 4.5 g/hr is a reasonable representation
of model development costs for all models subject to subpart AAA, with
some exceptions, described below. The Ferguson analysis shows that
several of the cost components are identical across scenarios. The
analysis claims, however, that other cost components vary according to
the specified emission reduction scenario. These differences were not
supported in the comments. For purposes of this analysis, we used the
7.5 to 4.5 g/hr scenario as a baseline case and modified it to reflect
the deletion of cost categories that were inappropriate for the NSPS
analyses, e.g., costs for trips to industry trade shows that would
occur for all products regardless of the NSPS.
We did accept the assumptions and logic related to evaluating the
tooling cost difference between steel stoves and cast iron stoves, as
both are commonly manufactured. Like Ferguson, we used an average of
their tooling costs to reflect product differences, even though this
may overestimate the number of cast iron stoves in the market place.
While we recognize the range in capital cost estimates provided both
prior to and after proposal of the draft standards leave room for
additional cost scenarios, especially the much lower cost scenario for
Woodstock Soapstone Stoves, the Ferguson costs represent the best
documented cost ranges and cost categories available at this time.
For the final cost analysis, we used the mean wood stove costs. For
our analyses, these model development costs represent feasible costs
for adjustable burn rate stoves and pellet stoves. For single burn rate
stoves, as we did at proposal, the analyses reflect that additional R&D
may be required to bring these stoves to qualifying levels. Rather than
doubling the total model development costs during the first 2 years as
we did at proposal, the new costs for the R&D/Engineering cost portion
of the total costs are doubled in the first 2 years, with ``normal''
model development proceeding thereafter.
Details of our responses to cost comments are in the RTC document
and the technical and cost memoranda in the docket for this final rule.
b. Central Heaters
At proposal, our analyses reflected that hydronic heaters and
forced-air furnaces would face the same model development costs as room
heaters. Some commenters objected to this characterization,
particularly based on the detailed hydronic heater cost estimates
located in Attachment 3 of the HPBA comments as prepared by NERA
Economic Consulting (May 2014).\14\ Appendix A of that document,
Hydronic Heater Cost Modeling (prepared by Ferguson, Andors & Company)

analysis.

from the HPBA available at https://www.regulations.gov/#!documentDetail;D=EPA-HQ-OAR-2009-0734-1643.
---------------------------------------------------------------------------

The HPBA costs for hydronic heaters were prepared with the same
methodology and overall assumptions as they used in development of the
wood heater costs. The Ferguson analysis provides cost estimates for
four categories of hydronic heater emission reductions, based on the
proposed emission levels consisting of modifying uncontrolled heaters
to comply with a new 0.32 lb/mmBtu emission limit, modifying the 0.32
lb/mmBtu heaters to comply with new emission limits of 0.15 or 0.06 lb/
mmBtu, and modifying a 0.15 lb/mmBtu heater to a new emission limit of
0.06 lb/mmBtu. The resulting cost components consisted of capital costs
per model (R&D, engineering labor, tooling, equipment integration,
preliminary testing, and other costs to design and manufacture the
modified wood stove model) and other fixed costs per model
(certification testing and safety testing, roll-out of the modified
products including store display models and burn programs, brochures,
user manuals, training and product discounts). The mid-point capital
costs presented by Ferguson range from $1,743,750 to $2,162,300
depending on the emission reduction range.\15\ We used these cost
estimates in our analysis.

As discussed earlier in section III.A, unlike the proposed rule,
the final rule contains a Step 1 PM emission limit of 0.32 lb/mmBtu and
a Step 2 PM emission limit of 0.10 lb/mmBtu, with no alternative three-
step PM emission limits. The comments overwhelmingly indicated that the
three-step PM emission limit approach was inferior not only
environmentally but also economically because it would, in effect,
require many small manufacturers to engage in two rounds of R&D rather
than one in order to obtain the same eventual endpoint.
The Step 1 PM emission limit cost for modifying uncontrolled
heaters to comply with 0.32 lb/mmBtu is a reasonable representation of
model development costs for all models subject to subpart QQQQ, with
some exceptions, described below. The Ferguson analysis shows that
several of the cost components are identical across scenarios. The
analysis claims that other cost components vary according to the
specified emission reduction scenario; however, no support was provided
for these claims in the Ferguson analysis. For purposes of our
analysis, we used the scenario of uncontrolled to 0.32 lb/mmBtu as a
baseline case and modified it to reflect the deletion of cost
categories that were inappropriate for the NSPS impact analyses, e.g.,
costs for trips to industry trade shows that would occur for all
products regardless of the NSPS.
For our final rule cost analysis, we used the mean hydronic heater
costs estimated in Table 5-2 of the final RIA. These model development
costs represent feasible costs for hydronic heaters. For forced-air
furnaces, as we did at proposal, our analysis included the additional
R&D that may be required to bring these heaters to qualifying levels.
Rather than doubling total model development costs during the first 2
years as we did at proposal, for the final rule analysis the R&D/
Engineering cost portion of the total costs are doubled in

[[Page 13690]]

the first 2 years, with ``normal'' model development proceeding
thereafter.
Details of our responses to cost comments are in the RTC document
and the technical and cost memoranda in the docket for this final rule.
2. Economic Impacts
As discussed in detail in the RIA and summarized in section D.1
above, we received numerous comments on the costs, and we have adjusted
our cost estimates as appropriate. Since the economic impacts are based
on the costs and other factors, we have adjusted the economic impacts
accordingly. The details of the adjustments are in the RIA, and a
summary is in sections IV.C and VI of this preamble.

F. Test Methods

1. Crib Wood vs. Cord Wood
We received a full range of comments on this issue, from complete
support for the proposed cord wood testing requirements to complete
opposition to requiring cord wood testing at this time. We considered
all comments and focused on those that discussed the data in detail. As
discussed earlier in section IV, based on the data and comments
submitted, we have determined that it is premature to require a cord
wood-based Step 2 PM emission limit at this time (except for forced-air
furnaces for which CSA B415.1-10 already specifies cord wood as the
test fuel). Rather, we are basing the Step 2 PM emission limit on crib
wood testing and including an alternative compliance option to meet an
emission limit based on cord wood testing, to encourage manufacturers
to certify with cord wood as soon as possible to provide consumers with
better information for their actual in-home-use performance. There are
some manufacturers that already achieve the cord wood emission level
and we expect that many more manufacturers will take this option and
submit data that will inform development of a required cord wood
certification test in a future rulemaking.
Based on the existence of a viable draft cord wood test method and
the expectation at proposal that the ASTM test methods for cord wood
would be complete soon after proposal and that significant testing of
wood heaters re-tuned to perform well on cord wood would occur before
promulgation of this final rule, the EPA proposed to require testing
only with cord wood for compliance with Step 2 emissions limits. We
still encourage manufacturers to design wood heaters that best
represent actual in-home-use performance on cord wood. However, the
ASTM cord wood test methods have not been completed and only limited
testing using the draft methods has occurred. For the cord wood
alternative compliance option, we will consider approval of requested
test methods on a case-by-case basis. We believe the current draft ASTM
test methods are sufficient to be used, upon request, for the cord wood
alternative compliance option until better test methods can be
developed. We will also be receptive to other alternative test method
requests that are adequately demonstrated, ideally according to the EPA
Method 301 validation procedures. (Note that forced-air furnaces are
tested according to the cord wood test method already specified in CSA
B415.1-10.
2. Compliance for Individual Burn Rates Versus Weighted Averages
We received a full range of comments on this issue, from complete
support for the proposed Step 2 compliance for individual burn rates to
using only the weighted averages similar to the 1988 NSPS. We
considered all comments and focused on those that discussed the data in
detail. As mentioned earlier in section IV, based on the data and
comments submitted, we have determined that the final rule will require
weighted averages for Step 2 in subpart AAA and individual burn rates
for Step 2 in subpart QQQQ.
For subpart AAA Step 2 emission limits, we proposed to require
certification compliance at the lowest burn rate (Category 1) and the
maximum burn rate (Category 4) rather than the weighted average of the
four burn rates, which was required in the 1988 rule. Many comments on
the proposal and the data in the NODA strongly supported the proposed
compliance determinations per individual burn rates. Many other
comments strongly opposed the proposal. Considering all of the comments
and focusing on the available test data, especially the EPA wood stove
certification test data by burn rate that we included in the July 1,
2014 NODA, we are requiring certification calculations based on the
weighted average of the four burn rates for subpart AAA. As discussed
earlier in section V.A, the data show that for weighted averages, 18
percent of noncatalytic stoves (that represent over 80 percent of the
market) achieve 2.0 g/hr. However, on an individual burn rate basis,
only 6 percent (7 of 110 stoves) achieve 2.0 g/hr, a relatively small
percentage of wood stoves manufactured today. This supports our
decision that a Step 2 limit of 2.0 g/hr, based on a weighted average
of the multiple burn rates, better represents BSER for wood stoves/
heaters subject to revised subpart AAA, compared to a Step 2 limit
based on individual burn rates.
For subpart QQQQ, the final rule retains the proposed Step 1 g/hr
emission cap for all burn rates (for hydronic heaters) and the Step 2
requirement for lb/mmBtu compliance at each burn rate (for both
hydronic heaters and forced-air furnaces) given concerns about the
sometimes very large emissions at individual burn rates. The emission
limits reflect the data available. For a more detailed discussion of
these comments and responses, see the RTC document in the docket for
this rule.
3. National Technology Transfer and Advancement Act (NTTAA)
We received a full range of comments on this issue, from complete
support to adamant disagreement with our determinations under the NTTAA
at proposal that some portions of some of the ASTM test methods were
not applicable or impractical for this rule because they did not
achieve the Agency's mission, goals and objectives. (The NTTAA directs
agencies to use voluntary consensus standards whenever applicable
methods are available unless they are impractical.) As discussed in the
proposal preamble in section VI.I, the rule incorporates some voluntary
consensus standards (VCS) by reference, including some ASTM methods and
CSA B415.1-10. We could not use some ASTM test methods and other VCS
because they were not applicable. That is, the inapplicable VCS did not
fully achieve the intent of this rule or the primary mission of the
Agency and many tribes, states and local agencies to protect human
health and the environment.
Some comments claimed that the EPA cannot take portions of VCS but
rather must only use the whole VCS. That position is inconsistent with
the intent of the NTTAA goal for reducing duplication of effort. That
is, using valuable portions of VCS helps reduce potential duplicative
efforts.
Some comments suggested that because the EPA unofficial
participants (the EPA employees who were not ASTM members but
participated in some of the calls) in certain ASTM test method
development efforts did not submit official negatives on the standard,
that somehow that meant that the EPA approved all of the details of the
draft ASTM test methods. The EPA participants often expressed that the
draft test methods were not fully applicable to the needs of the EPA
and states; but since the draft test methods

[[Page 13691]]

may meet some of the immediate needs of the industry participants, the
EPA did not want to stop the ASTM efforts to develop improved drafts.
Further, the NTTAA guidance explicitly states that Agency participation
does not indicate Agency approval or endorsement.
4. Real World, Cold Starts, Cycling, Moisture, Heat Demand
Many comments indicated a critical need for test methods that
reflect the ``real world'' with cord wood, cold starts, cycling,
moisture, heat demand and shorter averaging periods.
We strongly agree, and we will consider alternative cord wood test
method requests on a case-by-case basis until we are convinced that
improved test methods have been sufficiently demonstrated that they can
be relied upon for regulatory purposes. Additionally, we expect that
within the next few years we will receive enough ``real world'' cord
wood test data for the EPA to establish revised certification
requirements based on those test data.

G. Health Effects and Benefits

A more detailed summary of the comments is in the RTC document in
the docket.
1. Additional Health Outcomes
Several comments suggested that the EPA should expand its
assessment of health benefits.
The RIA includes all possible health impacts related to exposure to
wood combustion-related PM2.5. Table 7-1 of the RIA on human
health effects of ambient PM2.5 has an extensive list of the
above mentioned health endpoints that were considered and monetized,
including exacerbation of asthma among children. However, several were
assessed qualitatively due to time and resource limitations. Table 7-2
of the RIA shows the results of the assessed health incidence
reductions and related benefits from reduced PM2.5 exposure
associated with the proposed option.
2. Additional Pollutants and Outcomes
Comments suggested that the EPA should expand its assessment to
include benefits of reductions in CO and VOC and certain non- human
health-related benefits including: environmental degradation;
accelerated depreciation of capital; haze; contribution to
anthropogenic climate change; and harm to pets and livestock.
The EPA understands that the benefits assessment in the RIA
reflects only a subset of the benefits attributable to the health
effects reductions associated with ambient fine particles. Limitations
in data, time and resources prevented the EPA from quantifying the
impacts to, or monetizing the benefits from, several important benefits
categories, including benefits associated with the potential exposure
to ozone formation due to VOC emissions as a precursor, VOC emissions
as a PM2.5 precursor, CO, as well as ecosystem effects, and
visibility impairment due to the absence of air quality modeling data
for these pollutants among others in this analysis. However, the EPA
provided an extensive qualitative assessment of those benefits. The EPA
realizes that the benefits presented are an underestimate of the
overall benefits resulting from this rule and that these reductions
will help with ozone and PM planning.
3. Additional Benefits of Reducing Greenhouse Gases
Comments suggested that we expand the benefits analyses to include
the benefits of reducing greenhouse gases.
The EPA agrees that there will be added benefits from assessing
impacts of emission reductions of carbon dioxide (CO2),
methane and black carbon. While we know that these emissions will be
reduced along with the reductions of PM emission and the increases in
efficiency of the affected heaters, we do not have robust emissions
test data to make quantitative benefits analysis on climate change at
this time.
One commenter referred to the interagency Social Cost of Carbon
(SCC) estimates. The comment suggested that (1) EPA should use SCC to
reflect the monetized CO2 impacts of the proposed rule in
the RIA; and (2) EPA should use the SCC estimates published in 2010
instead of the updated SCC estimates published in 2013 because the
updated estimates have not been subject to public comment. The SCC
represents the monetized net damages of incremental changes in the
amount of CO2 emissions in a given year. Given that
CO2 impacts of the proposed rule were not analyzed, the SCC
estimates were not used in the RIA.
4. Uncertainty of ``Value per Statistical Life''
Commenters stated that the EPA's use of the Value per Statistical
Life (VSL)--that is, the monetized value attributable to mortality
reduction--is a source of uncertainty.
While the Agency is updating its guidance by incorporating the most
up-to-date literature and recent recommendations from the Science
Advisory Board Environmental Economics Advisory Committee (SAB-EEAC),
it has determined that a single, peer-reviewed estimate applied
consistently best reflects the SAB-EEAC advice until updated guidance
is available. Therefore, the EPA, after consulting with the Office of
Management and Budget (OMB), has decided to use the value established
in the 2000 Guidelines for all the EPA actions until a revised estimate
can be fully vetted.
The EPA will continue to look into approaches based on the best
available science as appropriate. The EPA will continue to recommend
the central estimate of $7.4 million ($2006), updated to the year of
the analysis, be used in all benefits analyses that seek to quantify
mortality risk reduction benefits regardless of the age, income, or
other population characteristics of the affected population until
revised guidance becomes available. This approach was vetted and
endorsed by the Agency when the 2000 ``Guidelines for Preparing
Economic Analyses'' were drafted. Although $7.4 million ($2006) remains
EPA's default guidance for valuing mortality risk changes, the Agency
has considered and presented others and may well consider the commenter
recommendation in future assessments.
We agree that there is uncertainty. Recent analyses have estimated
substantial increases in life expectancy and the number of life years
gained due to improved PM2.5 air quality. For example,
Hubbell (2006) estimated that reducing exposure to PM2.5
from air pollution regulations may result in an average gain of 15
years of life for those adults prematurely dying from PM2.5
exposure. In contrast, Pope et al. (2009) estimated changes in average
life expectancy at birth over a 20-year period, suggesting that
reducing exposure to air pollution may increase average life expectancy
at birth by approximately 7 months, which was 15 percent of the overall
increase in life expectancy at birth from 1980 through 2000.
5. Uncertainty in the EPA Analyses Regarding the Constant Benefits-per-
Ton Simplifying Assumption, Dose-Response Relationship, and Benefits
Transfer Approach
Comments suggested that the relationship between pollution and
human health is more complex than the EPA's simplifying assumptions and
thus more uncertain.
The EPA's methods for quantifying health benefits of emission
reductions are based on the best available peer-reviewed science and
methods that have withstood scrutiny from the EPA's independent Science
Advisory Board (SAB), the National Academy of

[[Page 13692]]

Sciences (NRC, 2002), and continuous interagency review.
The RIA references a peer-reviewed manuscript and technical support
document (TSD) that each describe the methods EPA employed to quantify
the per-ton benefit of reducing fine particle levels from various
sources. The air quality modeling attributed fine particle levels to
residential wood heaters, holding all other sectors constant--giving us
greater confidence that we have correctly characterized the air quality
and health impacts attributable to this sector.
With respect to the incidence of benefits among populations living
in locations already attaining the primary NAAQS, the EPA acknowledges
that primary NAAQS are set at a level deemed by the EPA Administrator
to be protective of public health with an adequate margin of safety. At
the same time, primary NAAQS are not set at a level of zero risk and
there is no known threshold below which PM2.5 does not cause
adverse health effects. Thus, the EPA recognizes that reducing the
emissions level in those areas could still have health benefits.
Additional detail of our responses is included in the final RIA.

VI. Summary of Environmental, Cost, Economic, and Non-Air Health and
Energy Impacts

The EPA estimates the total annualized average nationwide costs
associated with this rule would be $45.7 million ($2013) over the
timeframe of 2015 through 2020. The economic impacts for industries
affected by this rule over this same period, estimated as a percent of
annual compliance cost to sales, range from 1.1 percent for manufacture
of pellet stove models to 17.1 percent for manufacture of hydronic
heater models. These impacts do not presume any pass-through of impacts
to consumers. With pass-through to consumers, these impact estimates to
manufacturers will decline proportionate to the degree of pass-through.

A. What are the air quality impacts?

In section IV of the preamble to the proposed rule, we described
the procedure we used to determine the air quality impacts on the
industries affected by this rule. Following proposal, we revised the
standards for room heaters and central heaters based on public
comments. Table 6 is a summary of the revised estimated annual average
emissions reductions over years 2015 through 2020 resulting from
implementing the final NSPS compared to baseline conditions (for the
years analyzed in the final RIA). As in the proposal, we developed
emission factors for each appliance type and then applied those
emission factors to shipment data for each of the appliance types
subject to the final NSPS.\16\ We developed the emission factors using
the EPA Residential Wood Combustion (RWC) emission estimation tool,\17\
which is a Microsoft Access database that compiles nationwide RWC
emissions using county-level, process-specific data and calculations.
The compilation of such data is a large, important, continually
improving effort by the EPA and the states to ensure that we and the
states have access to the best information available. For the final
rule, we used the updated version of the tool. The updated tool
includes the results of a peer-reviewed emission testing study of
hydronic heaters conducted by the EPA Office of Research and
Development and the New York State Energy Research and Development
Agency. (The study was added to the docket prior to proposal but the
tool was not updated until after proposal.) The results of that study
show much higher emissions for hydronic heaters at baseline than we
estimated at proposal. We have used the updated emission factors
because they are based on the best available scientific information. We
summed the estimated nationwide number of appliances and the estimated
total tons of wood burned for each of the relevant product categories
in the inventory and then made some adjustments/assumptions to the
baseline RWC inventory to reflect emission characteristics specific to
new units. As described below, to avoid any potential for overstating
baseline emissions, we went a step further and assumed that all new
shipments will meet the current State of Washington Department of
Ecology limits, which are approximately 40 percent less than the 1988
NSPS.

Heaters. January 2015.
\17\ Emission factors are based on EPA's Residential Wood
Combustion Tool version 4.1 with updates from the 2012 EPA report
(Gullett et al. Environmental, Energy Market, and Health
Characterization of Wood-Fired Hydronic Heater, Final Report, June
2012).
---------------------------------------------------------------------------

Single burn rate stoves are not included in the RWC database as
separate identifiable units. For our analysis, we used the same
baseline emission factor as freestanding non-certified wood stoves. We
used the average tons burned per appliance factor as representative of
these stoves as well.
After calculating a baseline average emission rate/appliance (or
``emission inventory category''), we multiplied the total tons of wood
burned for the appliance by the RWC emission factor (adjusted as
appropriate) to calculate the total tons of PM2.5 emissions.
We divided this value by the number of appliances in the category to
calculate the baseline average PM2.5 emissions per
individual appliance. The next step was to develop emission factors
representing the final NSPS. The timing of the NSPS emission limits
used in this analysis matches the phased-in compliance dates.
For the subpart AAA analysis, we used HPBA data from their 2010
analysis that indicated that at least 90 percent (130 out of 145
catalytic, non-catalytic and pellet stoves combined) already meet the
Step 1 PM emission limit. Manufacturers are expected to focus on
existing models that already meet the Washington State DOE limits in
order to comply with the Step 1 PM emission limit. Furthermore,
certification data \18\ indicate that 26 percent of non-catalytic and
catalytic stoves combined and 70 percent of pellet stoves already meet
the Step 2 PM emission limit. For our analysis, we used 26 percent of
adjustable burn rate stoves and 70 percent of pellet stoves for the
percentages that can already meet the Step 2 PM emission limit without
intensive R&D efforts. Although previously unregulated and a less
developed technology than adjustable burn rate stoves, single burn rate
stove designs have been undergoing R&D in anticipation of the proposed
NSPS and cleaner designs are in progress.

model percentages meeting Step 2 standards. November 2014.
---------------------------------------------------------------------------

For the subpart QQQQ analysis for hydronic heaters, we note that
the Step 1 PM emission limit is the EPA ``Phase 2'' voluntary program
lb/mmBtu weighted average emission limit is already met by 50 hydronic
heater models built by U.S. manufacturers participating in the
voluntary program. We also note that 19 additional qualification tests
have been recently submitted to EPA and, if valid, all 19 will be added
as Phase 2 qualified models and Step 1 NSPS certified models. The NSPS
Step 2 PM emission limit is already met by 9 hydronic heater models
built by U.S. manufacturers participating in the voluntary program, as
well as over 100 European models per test method EN 303-05 and over 20
pellet boilers (U.S. and European) that have been qualified in the RHNY
program. Data indicate that at least 18 percent of current hydronic
heater model designs can meet the Step 2 emission limit without
intensive R&D efforts.

[[Page 13693]]

For the subpart QQQQ analysis for forced-air furnaces, we note that
the Step 1 PM emission limit is based on test data from certifications
under the Canadian standard B415.1-10 (circa 2010) and conversations
with industry regarding cleaner forced-air furnace models currently
being tested in R&D. As discussed earlier in this preamble, forced-air
furnace designs able to meet the Step 2 limit are based on technology
transferred from hydronic heater designs and/or wood stove designs.
Next we used data in the Frost & Sullivan Market (F&S) report \19\
on 2008 shipments by product category, and F&S revenue forecasts which
incorporated the weak economy in years 2009 and 2010, to calculate the
reduced number of shipments in years 2009 and 2010. Forced-air furnaces
were outside the scope of the F&S report. Instead, we used manufacturer
estimates of total industry sales in 2008 and applied the F&S market
factors to estimate shipments through 2010. The F&S wood stove numbers
included both certified and non-certified stoves, so we estimated
numbers of non-certified stove shipments out of the total reported wood
stove category (i.e., 40,000 single burn rate stoves shipped in 2008).
These shipments were deleted from the total wood stove category
shipments. We expanded the 2008 single burn rate estimate using the F&S
factors.

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

For years 2011 through 2029, estimated shipments are generally
based on a forecasted revenue growth rate of 2.0 percent, in keeping
with the average annual growth in real U.S. GDP predicted by the
Conference Board.\20\ Historically wood heater shipments have most
closely corresponded to GDP, housing starts, and price of wood relative
to natural gas. The overall trend in the projection is reasonable in
the absence of additional specific shipment projections. We did not
change the relative percentages of one type of residential wood heater
versus other types of residential wood heaters over this time period.
The only exceptions to the use of a 2.0 percent U.S. GDP-based growth
rate are for years 2012 and 2018, in which we used industry estimates
for hydronic heater and wood stove shipments, respectively. For year
2012, an HPBA consultant estimated there were 13,100 baseline hydronic
heater sales.\21\ For year 2018, the same HPBA consultant projected
there to be 100,000 wood stove sales.\22\ We adjusted our estimated
shipment data accordingly.

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

Our cost effectiveness analysis (CE) is based on industry data that
show that a given model design will often be sold for approximately 10
years before being redesigned (a 10-year ``model design lifespan'') and
that each individual stove will be used for 20 years before it is
replaced in a residence (a 20-year ``use/emitting appliance
lifespan''). These time periods were used to best characterize the
actual model design and use lifespans. For proposal, we used a 20-year
model design lifespan because many models developed for the 1988 NSPS
are still being sold (after 25 years), with many ``new'' models
retaining the same internal working parts with merely exterior cosmetic
changes. In response to comments on the proposed rule,\23\ however, in
which some industry representatives commented that a shorter model
lifespan is more typical, and provided data for models for several
manufacturers, we reduced the model design lifespan to 10 years for
this analysis. Regarding the emitting lifespan of the appliance, most
wood heaters in consumer homes emit for at least 20 years and often
much longer. Therefore, our CE analysis tracks shipments through year
2029 (using a 10-year design life for a model meeting the Step 2
emission limit in year 2020) and emissions through year 2048 (using a
20-year emitting life for an appliance shipped in year 2029).

B. What are the benefits?

Emission reductions associated with the requirements of this rule
will generate substantial health benefits by reducing emissions of
PM2.5, HAPs, as well as criteria pollutants and their
precursors, including CO and VOC. VOC are precursors to
PM2.5 and ozone. For this rule, we were only able to
quantify the monetized health co-benefits associated with reduced
exposure from directly emitted PM2.5. Our benefits reflect
the average of annual PM2.5 emission reductions occurring
between 2015 and 2020 (inclusive). We estimate the monetized
PM2.5-related health benefits of the residential wood
heaters NSPS in the 2015-2020 timeframe to be $3.4 billion to $7.6
billion (2013 dollars) at a 3-percent discount rate and $3.1 billion to
$6.9 billion (2013 dollars) at a 7-percent discount rate. (These
estimates are greater than the estimates at proposal because the
emission reduction estimates are greater, as discussed in section VI.A
of this preamble and the RIA.) Using alternate relationships between
PM2.5 and premature mortality supplied by experts, higher
and lower benefits estimates are plausible, but most of the expert-
based estimates fall between these two estimates.\25\ A summary of the
emission reduction and monetized benefits estimates for this rule at
discount rates of 3 percent and 7 percent is in Table 7 of this
preamble.

with reducing exposure to PM2.5 through reductions of PM2.5 precursors, such as NOX, and directly emitted
PM2.5. It is important to note that the monetized benefits do not include reduced health effects from exposure
to HAP, direct exposure to NO2, exposure to ozone, VOC, ecosystem effects, effects from black carbon or
visibility impairment.
b PM benefits are shown as a range from Krewski, et al. (2009) to Lepeule, et al. (2012).
c These models assume that all fine particles, regardless of their chemical composition, are equally potent in
causing premature mortality because the scientific evidence is not yet sufficient to allow differentiation of
effects estimates by particle type.

These benefit estimates represent the monetized human health
benefits for populations exposed to less PM2.5 from emission
limits established to reduce air pollutants in order to meet this rule.
Due to analytical limitations, it was not possible to conduct air
quality modeling for this rule. Instead, we used a ``benefit-per-ton''
approach to estimate the benefits of this rulemaking. To create the
benefit-per-ton estimates, this approach uses a model to convert
emissions of PM2.5 precursors into changes in ambient
PM2.5 levels and another model to estimate the changes in
human health associated with that change in air quality, which are then
divided by the emissions in specific sectors. These benefit-per-ton
estimates were derived using the approach published in Fann, et al.,
(2012),\26\ but they have since been updated to reflect these studies
and population data in the 2012 p.m. NAAQS RIA.\27\ Specifically, we
multiplied the benefit-per-ton estimates from the ``Residential Wood
Heaters'' category by the corresponding emission reductions.\28\ All
national-average benefit-per-ton estimates reflect the geographic
distribution of the modeled air quality. The air quality modeling may
not reflect the local variability in population density, meteorology,
exposure, baseline health incidence rates, or other local factors for
any specific location. More information regarding the derivation of the
benefit-per-ton estimates for this category is available in the
technical support document, which is referenced in footnote 26 and is
available in the docket.

These models assume that all fine particles, regardless of their
chemical composition, are equally potent in causing premature mortality
because the scientific evidence is not yet sufficient to allow
differentiation of effects estimates by particle type. Even though we
assume that all fine particles have equivalent health effects, the
benefit-per-ton estimates vary between precursors depending on the
location and magnitude of their impact on PM2.5 levels,
which drive population exposure.
It is important to note that the magnitude of the PM2.5
benefits is largely driven by the concentration response function for
premature mortality. We cite two key empirical studies, one based on
the American Cancer Society cohort study \29\ and the extended Six
Cities cohort study.\30\ In the RIA for this rule, which is available
in the docket, we also include benefits estimates derived from expert
judgments (Roman et al., 2008) as a characterization of uncertainty

Considering a substantial body of published scientific literature,
reflecting thousands of epidemiology, toxicology, and clinical studies,
the EPA's Integrated Science Assessment for Particulate Matter \31\
documents the association between elevated PM2.5
concentrations and adverse health effects, including increased
premature mortality. This assessment, which was reviewed twice by the
EPA's independent Clean Air Scientific Advisory Committee, concluded
that the scientific literature consistently finds that a no-threshold
model most adequately portrays the PM-mortality concentration-response
relationship. Therefore, in this analysis, the EPA assumes that the
health impact function for fine particles is without a threshold.

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

In general, we are more confident in the magnitude of the risks we
estimate from simulated PM2.5 concentrations that coincide
with the bulk of the observed PM concentrations in the epidemiological
studies that are used to estimate the benefits. Likewise, we are less
confident in the risk we estimate from simulated PM2.5
concentrations that fall below the bulk of the observed data in these
studies. Concentration benchmark analyses [e.g., lowest measured level
(LML) or one standard deviation below the mean of the air quality data
in the study] allow readers to determine the portion of population
exposed to annual mean PM2.5 levels at or above different
concentrations, which provides some insight into the level of
uncertainty in the estimated PM2.5 mortality benefits. There
are uncertainties inherent in identifying any particular point at which
our confidence in reported associations becomes appreciably less, and
the scientific evidence provides no clear dividing line. However, the
EPA does not view these concentration benchmarks as a concentration
threshold below which we would not quantify health benefits of air
quality improvements.
For this analysis, policy-specific air quality data are not
available. Thus, we are unable to estimate the percentage of premature
mortality associated with this specific rule's emission reductions at
each PM2.5 level. As a surrogate measure of mortality
impacts, we provide the percentage of the population exposed at each
PM2.5 level using the source apportionment modeling used to
calculate the benefit-per-ton estimates for this sector. Using the
Krewski, et al., (2009) study, 93 percent of the population is exposed
to annual mean PM2.5 levels at or above the LML of 5.8
[mu]g/m\3\. Using the Lepeule, et al., (2012) study, 67 percent of the
population is exposed above the LML of 8 [mu]g/m\3\. It is important to
note that baseline exposure is only one parameter in the health impact
function, along with baseline incidence rates, population, and change
in air quality. Therefore, caution is warranted when interpreting the
LML assessment for this rule.
Every benefit analysis examining the potential effects of a change
in environmental protection requirements is limited, to some extent, by
data gaps, model capabilities (such as geographic coverage) and
uncertainties in the underlying scientific and economic studies used to
configure the benefit and cost models. Despite these uncertainties, the
benefit analysis for this rule provides a reasonable indication of the
expected health benefits of the rulemaking under a set of reasonable
estimations.
One should note that the monetized benefits estimates provided
above do not include benefits from several important benefit
categories, including exposure to HAP, VOC and ozone exposure, as well
as ecosystem effects, visibility impairment and greenhouse gas impacts.
Although we do not have sufficient information or modeling available to
provide monetized estimates for these benefits in this rule, we include
a qualitative assessment of these unquantified benefits in the RIA \32\
for this final rule.

C. What are the cost impacts?

In analyzing the potential cost impacts of the NSPS, we considered
two types of impacts. The first was the impact to the manufacturer to
comply with the proposed standards. The second was the increase in
price of the affected unit. In both of these cases, we considered the
same input variables: Research and development (R&D) cost to develop
and certify complying model lines, certification costs (where these are
separate from R&D), reporting and recordkeeping costs, numbers of
shipments of each appliance category (modified, from Frost & Sullivan
report), number of manufacturers, and number of models per
manufacturer. This section of the preamble contains a summary of these
costs. For more detailed information, see the manufacturer cost impact
memo \33\ and unit cost memo \34\ in the docket. Unless otherwise
specified, all costs are in 2013 dollars.

Manufacturer Cost Impacts. January 2015.
\34\ Memo to USEPA from EC/R, Inc. Unit Cost Estimates of
Residential Wood Heating Appliances. January 2015.
---------------------------------------------------------------------------

As discussed in detail in section IV.C, we reviewed information
provided by HPBA and manufacturers. Based on this information, we
estimated \35\ average costs to develop a new model line. The estimates
of the cost of R&D are crucial to our estimates of overall costs and
economic impacts and greatly influence our decisions on BSER and
implementation lead times. We annualized the R&D costs over 6 years,
applied the NSPS implementation assumptions, and estimated the average
manufacturing cost per model line per manufacturer.
---------------------------------------------------------------------------

\35\ In developing average R&D costs, we used the highest
industry R&D estimates supplied for cost components we deemed
attributable to the NSPS, in order to avoid under-estimating
potential costs per model line. We also assumed no model
consolidation to avoid understating the number of model lines that
would undergo R&D nationwide.
---------------------------------------------------------------------------

The estimate of the number of model types was derived from
information provided by HPBA, individual manufacturers, and Internet
searches of product offerings. For numbers of manufacturers, we started
with HPBA data and modified the dataset based on Internet searches of
manufacturers of the major appliance types. Table 8 is a summary of the
nationwide average annual NSPS-related cost increases to manufacturers.
The average annual cost increases are presented over the 2015 to 2020
period consistent with the years analyzed in the RIA,\36\ but were also
analyzed over the 2015 to 2029 period. The 2015 to 2029 period
encompasses the 2015 NSPS compliance year through the life span of
models designed to meet the NSPS, as explained further below and in our
background analyses.\37\

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

To develop estimates of potential unit cost increases, we used
major variables including the estimated number of units shipped per
year, the costs to develop new models, baseline costs of models, and
the schedule by which the revised NSPS would be implemented. Both the
number of shipped units and the baseline costs of models
(manufacturers' cost not retail price) were initially based on data
from the Frost & Sullivan report with modifications to address
additional appliances or subsets of appliances and industry comments as
discussed in our background analyses.\38\ We also estimated the
potential additional manufacturing costs to make NSPS complying models.
These expenses result from the use of more expensive structural
materials, components to enhance good combustion, etc. We estimated the
following additional manufacturing costs per unit based on appliance
type:
---------------------------------------------------------------------------

\38\ Memo to USEPA from EC/R, Inc. Unit Cost Estimates of
Residential Wood Heating Appliances. January 2015.
---------------------------------------------------------------------------

Certified wood stoves and pellet stoves represent a well-
developed technology and we could not identify price differences
between models with lower emission levels compared to models with
higher emission levels. Some stoves with lower emission sell for less
than some stoves with higher emissions and vice versa. Therefore, we
have assumed no additional manufacturing costs.
One manufacturer estimated that it will cost an average of
$100 more to manufacture a lower emitting single burn rate product
(exclusive of recovering R&D cost), which we updated to 2013 ($),
approximately $110.\39\

We have limited information that indicates the cost to

is approximately 75 percent more, or $1,700 (exclusive of recovering
R&D cost).\40\
---------------------------------------------------------------------------

\40\ Confidential Business Information.
---------------------------------------------------------------------------

As can be seen in hydronic heater market survey results,
the prices of qualified model hydronic heaters range from $6,995 to
$15,395, with the average retail price of $10,193. We adjusted this
value to exclude the 25 percent retail markup, resulting in a
manufacturers' cost estimate of $8,154.\41\ We estimated an approximate
increase of $3,200 to manufacture a qualified unit compared to an
unqualified unit.

the Hearth, Patio and Barbecue Association. May 2014. p. 10.
---------------------------------------------------------------------------

Our next step was to develop the following incremental cost
formula: Cost of amortized R&D multiplied by number of models divided
by number of units shipped per year equals the incremental cost of
developing a new unit, spread over the number of units expected to be
sold during a given year in the 6-year model development period. In
developing this calculation, we included the concept that the R&D costs
per model line are recovered in the sales price of future models, which
means that the more units that are sold, the lower the incremental cost
per unit. For our unit cost analysis, we used a flat rate in
shipments--that is, future shipments over the 6-year model development
period would be equal to the shipments estimated in the first year of
the 6-year model development period (2015). The flat rate was used
because we had no basis for concluding that sales of a given model line
would increase or decrease over time due to market competition with
other wood heaters or non-wood heaters, changes in consumer demand,
changes in the relative price for that model compared to other models
or any other factors. Where there are additional manufacturing costs as
discussed above, we added these to the unit cost number. Table 9 shows
the change in cost to develop and manufacture a stove from baseline
(before the NSPS revisions) to after the NSPS revisions are
implemented. The economic impacts of these costs are discussed in
section C, ``What are the economic impacts?'' More information on both
the costs and economic impacts is available in the RIA.

D. What are the economic impacts?

The economic impacts of the rule are estimated using industry-level
estimates of annualized compliance cost to value of shipments
(receipts) for affected industries. In this case, cost-to-receipts
ratios approximate the maximum price increase needed for a producer to
fully recover the annualized compliance costs associated with a
regulation. Essentially, the revenues to producers will likely fully
cover the annualized compliance cost incurred by producers at this
maximum price increase. Any price increase above the cost-to-receipts
ratio provides revenues that exceed the compliance costs. These
industry level cost-to-receipts ratios can be interpreted as an average
impact on potentially affected firms in these industries. Cost-to-
receipts ratios for the affected product types range from 1.1 percent
for pellet heaters/stoves to up to 17.1 percent for hydronic heaters.
More

[[Page 13697]]

information on how these impacts are estimated can be found in Chapters
5 and 6 of the RIA.
In estimating the net benefits of regulation, the appropriate cost
measure is ``social costs.'' Social costs represent the welfare costs
of the rule to society and fully represent the cost impacts regardless
of whether they are ultimately borne by manufacturers or consumers.
Social costs are best approximated by the compliance costs estimated
for this rule. Thus, the annualized social costs are best estimated to
be $45.7 million, based on the estimate of costs to manufacturers and
assuming no cost pass-through to consumers. Several comments noted that
these potential price increases can often be offset by the homeowner in
one or two heating seasons by the reduced cost of fuel due to the
increased heating efficiencies. More information on how these social
costs are estimated can be found in Chapter 5 of the RIA.

E. What are the non-air quality health and energy impacts?

These NSPS are anticipated to have no impacts or only negligible
impacts on water quality or quantity, waste disposal, radiation or
noise. To the extent new NSPS models are more efficient, that would
lead to reduced wood consumption, thereby saving timber and preserving
woodlands and vegetation for aesthetics, erosion control, carbon
sequestration, and ecological needs.
It is difficult to determine the precise energy impacts that might
result from this rule. On the one hand, to the extent that the NSPS
wood-fueled appliance is more efficient, energy outputs per mass of
wood fuel consumed will rise. However, wood-fueled appliances compete
with other biomass forms as well as more traditional oil, electricity,
and natural gas. Robust data are not available for us to be able to
determine the potential for consumers to choose other types of fuels
and their associated appliances if the consumer costs of wood-fueled
appliances increase and at what level that increase would drive
consumer choice. Similarly, robust data are not available for us to
determine the degree to which better information on the energy
efficiency of the NSPS appliances will encourage consumers to choose
new wood-fueled appliances over other new appliances.

VII. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

This action is an economically significant regulatory action that
was submitted to the Office of Management and Budget (OMB) for review.
Any changes made in response to OMB recommendations have been
documented in the docket. The EPA prepared an analysis of the potential
costs and benefits associated with this action. This analysis,
``Regulatory Impact Analysis (RIA) for Residential Wood Heaters NSPS
Revision, Final Report'' (EPA-452/R-15-001), is available in the
docket.
A summary of the monetized benefits and net benefits for the final
rule at discount rates of 3 percent and 7 percent is in Table 1 of this
preamble, and a more detailed discussion of the benefits is found in
section IV.B of this preamble. For more information on the benefits
analysis, please refer to the RIA for this rulemaking, which is
available in the docket. For more information on the cost analysis,
please refer to the RIA or cost memoranda prepared for this rulemaking,
all of which is available in the docket.

B. Paperwork Reduction Act (PRA)

The information collection requirements in the rule have been
submitted for approval to OMB under the PRA. The Information Collection
Request (ICR) documents that the EPA prepared for each subpart have
been assigned the EPA ICR number 1176.12 for subpart AAA and ICR number
2442.02 for subpart QQQQ. You can find a copy of the ICR documents in
the docket for this rule, and they are briefly summarized here. The new
information collection requirements are not enforceable until OMB
approves them.
This final rule will require manufacturers of new residential wood
heating devices 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 quality control plan approved by an
independent certifying body. 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 quality assurance program inspections and
emissions test data, and seal and store the tested appliance.
Consistent with the current ICR for subpart AAA, we have included
costs to manufacture and 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 NSPS allows (voluntary) use of EPA
temporary labels for the cleanest heaters in order to provide consumers
the ability to select wood heaters that meet or exceed the Step 2
standards prior to the 2020 compliance date. This voluntary temporary
label option ends upon the 2020 compliance date. Furthermore, the
amended NSPS also allows (voluntary) use of temporary EPA labels to
indicate wood heaters that meet Step 2 based on cord wood instead of
crib wood, allowing consumers to select heaters better tuned to in-home
performance. The cost of the voluntary temporary labels are not
included because they are not required.
Test laboratories that want to conduct NSPS certification testing
will need to apply for approval, conduct proficiency testing and report
the results of all such testing. The approved laboratories must
maintain records of all certification tests, proficiency tests and
compliance audit test data.
The required notifications are used to inform the agency when a new
model line is expected to be tested. The EPA and states may then
observe the testing, if desired. Emissions test reports are needed as
these are the agency's record of a model line's initial capability to
comply with the emission limit, and serve as a record of the operating
conditions under which compliance was achieved. All information
submitted to the EPA for which a claim of confidentiality is made
(e.g., design drawings) 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.
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 prioritizing inspections and is of sufficient quality to be used as
evidence in court. We have reviewed all the current requirements and
have removed the portions of the recordkeeping that are not necessary.
The EPA considered how to minimize the potential ICR burdens and
has incorporated several features that make a major paperwork reduction
impact.

[[Page 13698]]

For example, the rule allows one representative heater to be tested for
a model line rather than requiring every heater to be tested. The
revised subpart AAA itself ``deems'' automatic EPA certification of
heaters that have EPA certifications under the 1988 NSPS that show that
they would meet the Step 1 emission limits until Step 2. That is, no
additional certification is required until Step 2. Also, the new
subpart QQQQ deems automatic EPA NSPS Step 1 certification for hydronic
heaters with valid EPA Phase 2 qualifications under the EPA Hydronic
Heater Partnership Agreement of October 12, 2011 or hydronic heaters or
forced-air furnaces certified by the NYSDEC that show compliance with
the Step 1 emission levels. That is, no additional certification is
required until Step 2. Also, residential pellet hydronic heaters/
boilers that have been qualified under the Renewable Heat New York
(RHNY) program will be automatically deemed EPA certified to meet the
NSPS Step 1 and no additional certification is required until Step 2
provided that they comply with the RHNY requirements for installation
and operation with adequate thermal storage.
Respondents/affected entities: Manufacturers of new residential
wood heaters and laboratories that conduct or plan to conduct wood
heater certification tests.
Respondent's obligation to respond: Mandatory under section 111 of
the CAA.
Estimated number of respondents: 72 respondents under subpart AAA
(66 manufacturers and 6 testing laboratories); 41 respondents under
subpart QQQQ (37 manufacturers and 4 testing laboratories).
Frequency of responses: once per model line, annually, biennially,
variable and/or infrequent.
Total estimated burden: 2,947 labor hours (per year) under subpart
AAA; 2,337 labor hours (per year) under subpart QQQQ. Burden is defined
at 5 CFR 1320.3(b).
Total estimated cost: $1,716,990 (per year) under subpart AAA,
includes $1,466,440 annualized capital and operation & maintenance
costs; $3,383,100 (per year) under subpart QQQQ, includes $3,191,200
annualized capital and operation & maintenance costs.
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 the
EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB
approves this ICR, the agency will announce that approval in the
Federal Register and publish a technical amendment to 40 CFR part 9 to
display the OMB control number for the approved information collection
activities contained in this final rule.

C. Regulatory Flexibility Act (RFA)

Pursuant to sections 603 and 609(b) of the RFA, the EPA prepared an
initial regulatory flexibility analysis (IRFA) for the proposed rule
and convened a Small Business Advocacy Review (SBAR) Panel to obtain
advice and recommendations from small entity representatives that
potentially would be subject to the rule's requirements. Summaries of
the IRFA and Panel recommendations are presented in the proposed rule
at 79 FR 6329.
As required by section 604 of the RFA, the EPA prepared a final
regulatory flexibility analysis (FRFA) for this action. The FRFA
addresses the issues raised by public comments on the IRFA for the
proposed rule. The complete FRFA is available for review in the docket
and is summarized here.
Reason Why Action Is Being Considered. As discussed
earlier in this preamble, this final rule was developed following CAA
section 111(b)(1)(B) review of the existing residential wood heater
NSPS, and because emissions from residential wood heaters can be a
significant source of air pollution, and thus adverse health effects,
in some areas.
Statement of Objectives and Legal Basis of Rule. As
discussed earlier in this preamble, the EPA is amending Standards of
Performance for New Residential Wood Heaters and adding one new
subpart, Standards of Performance for New Residential Hydronic Heaters
and Forced-Air Furnaces. This final rule achieves several objectives,
including applying updated emission limits that reflect BSER; improving
coverage of the broad suite of residential wood heaters; improving the
test methods; and streamlining the certification process. This final
rule does not include any requirements on heaters solely fired by coal,
gas or oil. This final rule does not establish new emissions limits for
existing heaters. This rule was developed under the authority of CAA
section 111.
Response to Any Comments to the Proposed Rule Filed by the
Chief Counsel for Advocacy of the SBA. The SBA's Chief Counsel for
Advocacy did not file any comments to the proposed rule.
Description and Estimate of the Number of Small Entities.
As discussed earlier in this preamble, small entities that the EPA
anticipates being affected by this rule will include almost all
manufacturers of residential wood heaters. We estimate that roughly
250-300 U.S. companies manufacture residential wood heaters.
Approximately 90 percent of these manufacturers meet the SBA small-
entity definition of having fewer than 500 employees.
Description of reporting, recordkeeping and other
compliance requirements. The reporting and recordkeeping requirements
are described in the section immediately above (B. Paperwork Reduction
Act). As discussed there, the information collection requirements
(ICR), including reporting and recordkeeping, in this rule have been
submitted for approval to OMB under the Paperwork Reduction Act, 44
U.S.C. 3501 et seq. For subpart AAA, we estimated the potential annual
burden averaged over the first 3 years of the ICR to be a total of
2,947 labor hours per year at a total labor cost of $250,551 per year
and an average annual labor burden per response of 12 hours. For
subpart QQQQ, we estimated 2,337 labor hours per year at a total labor
cost of $191,904 per year and an average annual labor burden per
response of 12 hours.
Description of other compliance requirements. As described
earlier in this preamble, this rule will apply updated emission limits
that reflect the current best systems of emission reduction (BSER) and
improve the coverage of the expanded variety of types of residential
wood heaters. We estimate the NSPS's total annualized average
nationwide costs will be $45.7 million (2013$) over the 2015 through
2020 period. The economic impacts for industries affected by this rule
over this same period range from 1.1 percent for manufacture of pellet
stove models to as much as 17.1 percent compliance cost-to-sales
estimate for manufacture of hydronic heater models. These impacts do
not presume any pass-through of impacts to consumers. With pass-through
to consumers, these impact estimates to manufacturers will decline
proportionate to the degree of pass-through. We estimate that small
entities will have annualized costs of greater than 1 percent of their
sales in all affected industries, and NAICS 442299 with receipts less
than $10 million. Those establishments in NAICS 332510, 333414 and
423720 with cost-to-receipt ratios higher than 1 percent account for 90
percent of small entities affected in these industries. Establishments
in NAICS 442299 with cost-to-receipt ratios higher than 1 percent
account for

[[Page 13699]]

99 percent of small entities affected in these industries.
Relevant federal rules that may overlap or conflict with
this rule. There are no other relevant federal rules.
Significant alternatives. The significant alternatives to
this rule, especially those that might minimize potential impacts on
small entities, are presented in the remainder of this section.
As required by section 609(b) of the RFA, as amended by the Small
Business Regulatory Enforcement Fairness Act (SBREFA), the EPA also
convened a Small Business Advocacy Review Panel (Panel) to obtain
advice and recommendations of representatives of the small entities
that potentially would be subject to the rule's requirements. The
following paragraphs describe the process, the type of small entity
representatives, the outreach efforts and the Panel members.
Well before beginning the formal SBREFA process, the EPA actively
engaged in outreach with HPBA, MHA and PFI and many of their member
companies to discuss the rule under development and to provide these
contacts with an early opportunity to ask questions and discuss their
concerns.\42\ The EPA provided each small business with general
information on the SBREFA process and background information on the
NSPS rulemaking process and current schedule.
---------------------------------------------------------------------------

\42\ Also, as noted in the proposal preamble in the discussion
of development of the proposed hydronic heater emission limits, the
EPA worked with the hydronic heater industry in 2006 to develop a
voluntary partnership program to encourage manufacture of cleaner
models, www.epa.gov/burnwise/participation.
---------------------------------------------------------------------------

Based on consultations with the SBA, and resulting from solicited
self-nominations, we prepared a list of 30 potential Small Entity
Representatives (SERs), from residential wood heating appliance
manufacturers (wood heaters, pellet heaters/stoves, hydronic heaters,
forced-air furnaces and masonry heaters), other wood-burning appliance
manufacturers (fireplaces, cook stoves), equipment suppliers, chimney
sweeps, test laboratories, masons and trade associations. Once the
official pre-Panel process began and potential SERs were identified,
the EPA held an outreach meeting with the potential SERs and invited
representatives from the Office of Advocacy of the Small Business
Administration (OA/SBA) and the Office of Information and Regulatory
Affairs within the Office of Management and Budget (OIRA/OMB) on June
29, 2010, to solicit their feedback on the upcoming proposed
rulemaking. Representatives from 26 of the 30 companies and
organizations that we selected as potential SERs for this SBREFA
process participated in the meeting (in person and by phone). At that
meeting, the EPA solicited written comments from the potential SERs,
which were later summarized and shared with the Panel as part of the
convening document.
The SBAR Panel convened on August 4, 2010. The Panel consisted of
representatives of the EPA, OA/SBA and OIRA/OMB. The Panel held a
formal outreach meeting/teleconference with the SERs on August 25,
2010. To help the SERs prepare for this meeting, on August 11, 2010,
the Panel sent a list of questions, preliminary cost information and
other materials to each of the SERs via email. Additional materials
were emailed to the SERs on August 19, 2010. The Panel provided the
opportunity for questions and comment during the meeting on various
aspects of the proposal being developed, including the expanded scope
of the rule, changes to the current requirements under consideration,
preliminary cost information and follow up from the June 29, 2010,
meeting on the SERs' ideas for regulatory flexibility. During the
August 25 meeting, SERs voiced general support for the planned proposed
rule and shared specific concerns with the Panel members. As a result
of this meeting, the EPA received many useful verbal comments, and the
EPA received many helpful written comments by September 10, 2010.
Consistent with the RFA/SBREFA requirements, the Panel evaluated
the assembled materials and small-entity comments on issues related to
elements of the Interim Regulatory Flexibility Analysis. A copy of the
Panel final full report is included in the docket for this rule. We
have attempted to follow the Panel's recommendations to the degree we
can while also ensuring that the options are practicable, enforceable,
environmentally sound and consistent with the CAA. For those
recommendations not adopted by the EPA, we included an explanation at
proposal for why we rejected them.
Further information about the panel is provided in the FRFA and the
SBREFA Panel final report that are included in the docket for this
rule.
In addition, the EPA is preparing a Small Entity Compliance Guide
to help small entities comply with this rule. Small entities can obtain
of a copy of this guide at https://www.epa.gov/rfa/compliance-guides.html or https://www2.epa.gov/residential-wood-heaters. We expect
the Small Entity Compliance Guide to be available by April 2015.

D. Unfunded Mandates Reform Act (UMRA)

This action does not contain any unfunded mandates of $100 million
or more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. This action imposes
no enforceable duty on any state, local or tribal governments. The
nationwide annualized average compliance cost of this rule for directly
affected appliances is $45.7 million/yr in the 2015-2020 timeframe
(2013$). Therefore, this final rule is not be subject to the
requirements of sections 202 or 205 of the UMRA.
This final rule is also not subject to the requirements of section
203 of UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments. The rule does not
apply to such governments and will impose no obligations upon them.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government.
The rule will not impose any requirements on state and local
governments. Thus, Executive Order 13132 does not apply to this final
rule. Although section 6 of Executive Order 13132 does not apply to
this final action, the EPA did consult with representatives of state
and local governments in developing this action. In the spirit of
Executive Order 13132 and consistent with the EPA policy to promote
communications between the EPA and state and local governments, the EPA
solicited comment on the proposed rule from state and local officials.
We have responded to their significant comments in this preamble and in
the RTC document.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

This action does not have tribal implications as specified in
Executive Order 13175. This rule will not impose any requirements on
tribal governments. Thus, Executive Order 13175 does not apply to this
action.
Consistent with the EPA Policy on Consultation and Coordination
with Indian Tribes, the EPA consulted with tribal officials during the
development of this action. A summary of that consultation is provided
here. During

[[Page 13700]]

the development of the proposed rulemaking, the EPA conducted outreach
with numerous tribal representatives to provide opportunities for input
prior to development of the proposed rule. We provided information at
the July 2010, National Tribal Forum/National Tribal Air Association
(NTAA) meeting in Albuquerque, New Mexico, and the November 2010, EPA
Region 10 Tribal Leaders Summit in Juneau, Alaska. We also presented
information on this proposed rulemaking in the April 2010, issue of
Tribal Air News and during the EPA/NTAA tribal workgroup conference
calls (April 2010, July 2010, August 2010, and May 2013). Specifically,
we received input from the EPA/NTAA tribal workgroup members on
culturally relevant exclusions from the proposed standards. We agreed
with their input, clarified that we do not intend to regulate
ceremonial fires, and added a definition to the rule to exclude
traditional Native American bake ovens.
On February 18, 2011, the EPA mailed letters to about 600 elected
tribal leaders in the U.S. offering an opportunity for consultation on
this proposal. We received requests from six tribes. These tribes
agreed to discuss this proposal with us in a conference call held on
March 22, 2011. The tribes were very supportive of this proposal and
provided some helpful clarifications of definitions (e.g., Native
American bake ovens) that we have incorporated in this proposal. We
continued to provide updates on the rule on the EPA/NTAA conference
calls and to offer opportunities to tribal leaders for consultation. On
January 30, 2014, and September 25, 2014, we presented updates for
tribes at the monthly EPA/NTAA conference calls.
The air quality and public health benefits to be achieved by this
rule will benefit tribes. The emissions occur in neighborhoods and
affect people in their homes. To the extent that populations are
particularly sensitive to asthma, this rule will help.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

This action is not subject to Executive Order 13045 because the EPA
does not believe the environmental health risks or safety risks
addressed by this action present a disproportionate risk to children.
This action's health and risk assessments are contained in the RIA as
well as the report ``Analysis of Exposure to Residential Wood
Combustion Emissions for Different Socio-Economic Groups'' \43\ which
shows that on a nationwide basis, cancer risks due to residential wood
smoke emissions among disadvantaged population groups generally are
lower than the risks for the general population due to residential wood
smoke emissions. One of the demographic variables examined for this
report was that of people 18 years and younger. The full report is
available in the docket.
---------------------------------------------------------------------------

\43\ ``Analysis of Exposure to Residential Wood Combustion
Emissions for Different Socio-Economic Groups, Revised Draft
Report.'' Prepared for Gil Wood, U.S. EPA, Office of Air Quality
Planning and Standards, Research Triangle Park, NC. Prepared by EC/R
Inc., EPA Contract No. EP-D-05-085, Work Assignment No. 4-3. April
22, 2010.
---------------------------------------------------------------------------

This final rule is expected to reduce environmental impacts for
everyone, including children. This action promulgates emissions limits
at the levels based on BSER, as required by the CAA. Based on our
analysis, we believe this rule will not have a disproportionate impact
on children, and, in fact, will result in improvements to children's
health. These emissions happen in neighborhoods and affect people in
their homes. To the extent that children are particularly sensitive to
asthma, this rule will help.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

This action is not a ``significant energy action'' because it is
not likely to have a significant adverse effect on the supply,
distribution or use of energy. Further, we have concluded that this
rule is not likely to have any significant adverse energy effects. In
general, we expect the NSPS to improve technology, including energy
efficiency. Reducing emissions and increasing efficiency might increase
the use of wood fuel, which would relieve pressure on traditional coal
or petroleum based energy sources. However, as described in section
VI.E, it is difficult to determine the precise energy impacts that
might result from this rule. This is because wood-fueled appliances
compete with other biomass forms as well as more traditional oil,
electricity and natural gas. Robust data are not available to determine
the potential conversion to other types of fuels and their associated
appliances if the consumer costs of wood-fueled appliances increase and
at what level that increase would drive consumer choice.

I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR
Part 51

This action involves technical standards. The EPA has decided to
use several VCS ASTM International test methods, in full or in part,
including the following:
E2515-11 ``Standard Test Method for Determination of
Particulate Matter Emissions Collected by a Dilution Tunnel.'' This
test method is applicable for the determination of particulate matter
emissions from solid-fuel-burning appliances including woodstoves,
pellet-burning appliances, factory-built fireplaces, masonry
fireplaces, masonry heaters, indoor furnaces, and indoor and outdoor
hydronic heaters within a laboratory environment;
E2779-10 ``Standard Test Method for Determining
Particulate Matter Emissions from Pellet Heaters.'' This test method
covers the fueling and operating protocol for determining particulate
matter emissions from fires in pellet or other granular or particulate
biomass burning room heaters and fireplace inserts;
E2780-10 ``Standard Test Method for Determining
Particulate Matter Emissions from Wood Heaters.'' This test method
covers the fueling and operating protocol for determining particulate
matter emissions from wood fires in wood-burning room heaters and
fireplace inserts as well as determining heat output and efficiency;
and
E2618-13 ``Standard Test Method for Measurement of
Particulate Matter Emissions and Heating Efficiency of Outdoor Solid
Fuel-Fired Hydronic Heating Appliances.'' This test method applies to
wood-fired or automatically fed biomass burning hydronic heating
appliances. These appliances transfer heat to the indoor environment
through circulation of a liquid heat exchange media such as water or a
water-antifreeze mixture.
In addition, we determined that the VCS ASTM E871-82 (Reapproved
2013), ``Standard Test Method for Moisture Analysis of Particulate Wood
Fuels'' is acceptable as an alternative to that portion of the EPA
Methods 5H and 28. ASTM E871-82 (Reapproved 2013) covers the
determination of total weight basis moisture in the analysis sample of
particulate wood fuel. These VCS test methods are available for
purchase from ASTM International, 100 Barr Harbor Drive, P.O. Box
CB700, West Conshohocken, Pennsylvania 19428-2959, (800) 262-1373,
https://www.astm.org. A hard copy of this material is also available for
viewing in

[[Page 13701]]

the docket for this rule (Docket ID# EPA-HQ-OAR-2009-0734), the EPA
Docket Center, Public Reading Room, EPA WJC West, Room 3334, 1301
Constitution Ave. NW., Washington, DC. The telephone number for the
Public Reading Room is (202) 566-1744, and the telephone number for the
EPA Docket Center is (202) 566-1742.
The EPA will also use, in part, the following test VCS CSA method
available at the CSA Web site https://shop.csa.ca/en/canada/fuel-burning-equipment/b4151-10/invt/27013322010/:CSA_B415.1-10
``Performance Testing of Solid-fuel-burning Heating Appliances.'' This
standard specifies requirements for performance testing of solid-fuel-
burning heating appliances, including maximum emission rates. This
standard also specifies a method for determining heat outputs,
appliance efficiencies, emission levels and composition, and flue gas
flow rates. A hard copy of this material is also available for viewing
in the docket for this rule (Docket ID# EPA-HQ-OAR-2009-0734) at the
EPA Docket Center located at the address and telephone numbers above.
Finally, we will use, in part, the following VCS test method,
European National (EN) standard prepared by the European Union: EN 303-
5 ``Heating boilers for solid fuels, hand and automatically stoked
nominal heat output of up to 1025 MBtu--Terminology, requirements,
testing, and marketing.'' This EN standard applies to heating boilers
including safety devices up to a nominal heat output of 500 kilowatts,
which are designed for the burning of solid fuels only and are operated
according to the instructions of the boiler manufacturer. This EN
standard material is available for purchase at https://www.en-standard.eu/csn-en-303-5-heating-boilers-part-5-heating-boilers-for-solid-fuels-manually-and-automatically-stoked-nominal-heat-output-of-up-to-500-kw-terminology-requirements-testing-and-marking/?gclid=CMv3wrbFrsACFU4F7Aod3yoAcw. A hard copy of this material is also
available for viewing in the docket for this rule (Docket ID# EPA-HQ-
OAR-2009-0734), at the EPA Docket Center located at the address and
telephone numbers above. We believe that all the methods listed above
have some positive aspects that can help stakeholders determine
emissions under various operation conditions. For more details, please
refer to section 6 of the RTC document.
The search identified five other VCS that were potentially
applicable for this rule in lieu of the EPA reference methods. However,
the EPA determined that the five candidate VCS would not be applicable
and practical due to lack of equivalency, documentation, validation
data and other important technical and policy considerations. The five
VCS and other information and conclusion, including the search and
review results, are in the docket for this rule. The EPA solicited
comments on this aspect of the proposed rulemaking. Specifically, we
invited the public to identify potentially applicable voluntary
consensus standards and to explain why such standards, in whole or in
part, should or should not be used in this regulation. The EPA's
responses to the significant comments are presented in section V of
this preamble and in section 6 of the RTC document.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income
or indigenous populations because it does not affect the level of
protection provided to human health or the environment. The results of
this evaluation are contained in the report ``Analysis of Exposure to
Residential Wood Combustion Emissions for Different Socio-Economic
Groups'' which shows that on a nationwide basis, cancer risks due to
residential wood smoke emissions among disadvantaged population groups
generally are lower than the risks for the general population due to
residential wood smoke emissions.\44\ Rather, the rule increases the
level of environmental protection for all affected populations without
having any disproportionately high and adverse human health or
environmental effects on any population, including any minority, low-
income or indigenous population.
---------------------------------------------------------------------------

\44\ ``Analysis of Exposure to Residential Wood Combustion
Emissions for Different Socio-Economic Groups, Revised Draft
Report.'' Prepared for Gil Wood, U.S. EPA, Office of Air Quality
Planning and Standards, Research Triangle Park, NC. Prepared by EC/R
Inc., EPA Contract No. EP-D-05-085, Work Assignment No. 4-3. April
22, 2010.
---------------------------------------------------------------------------

This rule establishes national standards that will reduce primarily
PM emissions from new residential wood heaters and, thus, is expected
to decrease the amount of these emissions to which all affected
populations are exposed. These emissions happen in many neighborhoods
nationwide, including in minority and low-income neighborhoods and
affect people in their homes. To the extent that minority populations
and low-income populations are more vulnerable, this rule will help.

K. Congressional Review Act (CRA)

This action is subject to the CRA, and the EPA will submit a rule
report to each House of the Congress and to the Comptroller General of
the United States. This action is a ``major rule'' as defined by 5
U.S.C. 804(2).

American or Canadian safety standards, as documented by a permanent
label from a nationally recognized certification body affixed on each
unit sold, and that said safety listing only allows operation of the
fireplace with doors fully open. Operation with any required safety
screen satisfies this requirement.
(2) The model line has a safety listing that allows operation with
doors closed, has no user-operated controls other than flue or outside
air dampers that can only be adjusted to either a fully closed or fully
opened position, and the requirements in either paragraph (2)(i) or

as intended to be used primarily for aesthetic enjoyment and not as a
room heater, as demonstrated by product literature (including owner's
manuals), advertising targeted at the trade or public (including web-
based promotional materials) or training materials is presumptively a
fireplace model line.
(ii) The presumption in paragraph (3)(i) of this definition can be
rebutted by test data from an EPA-approved test laboratory reviewed by
an EPA-approved third-party certifier that were generated when
operating the appliance with the door(s) closed, and that demonstrate
an average stack gas carbon dioxide (CO2) concentration over
the duration of the test run equal to or less than 5.00 percent and a
ratio of the average stack gas CO2 to the average stack gas
carbon monoxide (CO) equal to or greater than 15:1. The stack gas
average CO2 and CO concentrations for the test run shall be
determined in accordance with the requirements in CSA B415.1-10 (IBR,
see Sec. 60.17), clause 6.3, using a sampling interval no greater than
1 minute. The average stack gas CO2 and CO concentrations
for purposes of this determination shall be the average of the stack

Sec. 60.533 What compliance and certification requirements must I
meet and by when?

(a) Certification requirement. Each affected wood heater must be
certified to be in compliance with the applicable emission standards
and other requirements of this subpart. For each model line
manufactured or sold by a single entity (e.g., company or
manufacturer), compliance with applicable emission standards of Sec.
60.532 must be determined based on testing of representative affected
wood heaters within the model line. If one entity licenses a model line
to another entity, each entity's model line must be certified. If an
entity intends to change the name of the entity or the name of the
model, the manufacturer must apply for a new certification 60 days
before the intended name change.
(1) Except for model lines meeting the requirements of paragraph
(h)(1) of this section, on or after May 15, 2015, the manufacturer must
submit to the Administrator the information required in paragraph (b)
of this section and follow either the certification process in
paragraphs (c) through (e) of this section or the third-party
certifier-based application process specified in paragraph (f) of this
section.

but must designate on the drawings the dimensions of each component
listed in paragraph (k) of this section. Manufacturers must identify
tolerances of components listed in paragraph (k)(2) of this section
that are different from those specified in that paragraph, and show
that such tolerances cannot reasonably be anticipated to cause wood
heaters in the model line to exceed the applicable emission limits. The
drawings must identify how the emission-critical parts, such as air
tubes and catalyst, can be readily inspected and replaced.
(3) A statement whether the firebox or any firebox component
(including the materials listed in paragraph (k)(3) of this section)
will be composed of material different from the material used for the
firebox or firebox component in the wood heater on which certification
testing was performed, a description of any such differences and
demonstration that any such differences may not reasonably be
anticipated to adversely affect emissions or efficiency.

not used in the calculations and, for any test runs not completed, the
data collected during the test run and the reason(s)

[[Page 13706]]

that the test run was not completed and why. The burn rate for the low
burn rate category must be no greater than the rate that an operator
can achieve in home use and no greater than is advertised by the
manufacturer or retailer. The test report must include a summary table
that clearly presents the individual and overall emission rates,
efficiencies and heat outputs. Submit the test report and all
associated required information, according to the procedures for
electronic reporting specified in Sec. 60.537(f).
(6) A copy of the warranties for the model line, which must include
a statement that the warranties are void if the unit is used to burn
materials for which the unit is not certified by the EPA and void if
not operated according to the owner's manual.
(7) A statement that the manufacturer will conduct a quality
assurance program for the model line that satisfies the requirements of
paragraph (m) of this section.
(8) A statement describing how the tested unit was sealed by the

party certifier are allowed to submit information on behalf of the
manufacturer, including any claimed to be CBI.
(12) A statement that the manufacturer will place a copy of the
certification test report and summary on the manufacturer's Web site
available to the public within 30 days after the Administrator issues a
certificate of compliance.
(13) A statement of acknowledgment that the certificate of
compliance cannot be transferred to another manufacturer or model line
without written approval by the Administrator.
(14) A statement acknowledging that it is unlawful to sell,
distribute or offer to sell or distribute an affected wood heater
without a valid certificate of compliance.
(15) Contact information for the responsible representative of the
manufacturer and all authorized representatives, including name,
affiliation, physical address, telephone number and email address.
(c) Administrator approval process. (1) The Administrator may issue
a certificate of compliance for a model line if the Administrator
determines, based on all information submitted by the applicant and any
other relevant information available, that:
(i) A valid certification test demonstrates that the representative
affected wood heater complies with the applicable emission standards in
Sec. 60.532;
(ii) Any tolerances or materials for components listed in paragraph
(k)(2) or (3) of this section that are different from those specified
in those paragraphs may not reasonably be anticipated to cause wood
heaters in the model line to exceed the applicable emission limits; and
(iii) The requirements of paragraph (b) of this section have been
met.
(2) The Administrator will deny certification if the Administrator
determines that the criteria in paragraph (c)(1) of this section have
not been satisfied. Upon denying certification under this paragraph,
the Administrator will give written notice to the manufacturer setting
forth the basis for this determination.
(d) Level of compliance certification. The Administrator will issue
the certificate of compliance for the most stringent particulate matter
emission standard that the tested representative wood heater meets
under Sec. 60.532.
(e) Conditional, temporary certificate of compliance. A
conditional, temporary certificate of compliance may be granted by the
Administrator until May 16, 2016 based on the manufacturer's submittal
of a complete certification application meeting all the requirements in
Sec. 60.533(b). The application must include the full test report by
an EPA-approved laboratory and all required compliance statements by
the manufacturer with the exception of a certificate of conformity by
an EPA-approved third-party certifier. The conditional, temporary
certificate of compliance would allow manufacture and sales of the
affected wood heater model line until May 16, 2016 or until the
Administrator completes the review of the application, whichever is
earlier. By May 16, 2016, the manufacturer must submit a certificate of
conformity by an EPA-approved third-party certifier.
(f) Third-party certifier-based application process. (1) Any
manufacturer of an affected wood heater must apply to the Administrator
for a certificate of compliance for each model line. The manufacturer
must meet the following requirements:
(i) The manufacturer must contract with a third-party certifier for
certification services. The contract must include regular (at least
annual) unannounced audits under ISO-IEC Standard 17065 to ensure that
the manufacturer's quality assurance plan is being implemented. The
contract must also include a report for each audit under ISO-IEC
Standard 17065 that fully documents the results of the audit. The
contract must include authorization and requirement for the third-party
certifier to submit all such reports to the Administrator and the
manufacturer within 30 days of the audit. The audit report must
identify deviations from the manufacturer's quality assurance plan and
specify the corrective actions that need to be taken to address each
identified deficiency.
(ii) The manufacturer must submit the materials specified in
paragraph (b) of this section and a quality assurance plan that meets
the requirements of paragraph (m) of this section to the third-party
certifier. The quality assurance plan must ensure that units within a
model line will be similar in all material respects that would affect
emissions to the wood heater submitted for certification testing, and
it must include design drawings for the model line.
(iii) The manufacturer must apply to the third-party certifier for
a certification of conformity with the applicable requirements of this
subpart for the model line.
(A) After testing by an approved test laboratory is complete,
certification of conformity with the emission standards in Sec. 60.532
must be performed by the manufacturer's contracted third-party
certifier.
(B) The third-party certifier may 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 specified in Sec. 60.532; the quality assurance plan is
adequate to ensure that units within the model line

[[Page 13707]]

will be similar in all material respects that would affect emissions to
the wood heater submitted for certification testing; and that the
affected heaters would meet all applicable requirements of this
subpart.
(iv) The manufacturer must then submit to the Administrator an
application for a certificate of compliance that includes the
certification of conformity, quality assurance plan, test report and
all supporting documentation specified in paragraph (b) of this
section.
(v) The submission also must include a statement signed by a
responsible official of the manufacturer or authorized representative
that the manufacturer has complied with and will continue to comply
with all requirements of this subpart for certificate of compliance and
that the manufacturer remains responsible for compliance regardless of
any error by the test laboratory or third-party certifier.
(2) The Administrator will issue to the manufacturer a certificate
of compliance for a model line if it is determined, based on all of the
information submitted in the application for certification and any
other relevant information, that:
(i) A valid certification of conformity has demonstrated that the
representative affected wood heater complies with the applicable
emission standards in Sec. 60.532;
(ii) Any tolerances or materials for components listed in paragraph
(k)(2) or (3) of this section that are different from those specified
in those paragraphs may not be reasonably anticipated to cause wood
heaters in the model line to exceed the applicable emission limits;
(iii) The requirements of paragraph (b) of this section have been
met; and
(iv) A valid certificate of conformity for the model line has been
prepared and submitted.
(3) The Administrator will deny certification if the Administrator
determines that the criteria in paragraph (f)(2) of this section have
not been satisfied. Upon denying certification under this paragraph,
the Administrator will give written notice to the manufacturer setting
forth the basis for the determination.
(g) Waiver from submitting test results. An applicant for
certification may apply for a potential waiver of the requirement to
submit the results of a certification test pursuant to paragraph (b)(5)
of this section, if the wood heater meets either of the following
conditions:
(1) The wood heaters of the model line are similar in all material
respects that would affect emissions, as defined in Sec. 60.531, to
another model line that has already been issued a certificate of
compliance. A manufacturer that seeks a waiver of certification testing
must identify the model line that has been certified, and must submit a
copy of an agreement with the owner of the design permitting the
applicant to produce wood heaters of that design.
(2) The manufacturer has previously conducted a valid certification
test to demonstrate that the wood heaters of the model line meet the
applicable standard specified in Sec. 60.532.
(h) Certification period. Unless revoked sooner by the
Administrator, a certificate of compliance will be valid for the
following periods as applicable:
(1) For a model line that was previously certified as meeting the
1990 Phase II emission standards under the 1988 NSPS, in effect prior
to May 15, 2015, at an emission level equal to or less than the 2015
emission standards in Sec. 60.532(a), the model line is deemed to have
a certificate of compliance for the 2015 emission standards in Sec.
60.532(a), which is valid until the effective date for the 2020
standards in Sec. 60.532(b) (i.e., until May 15, 2020).
(2) For a model line certified as meeting emission standards in
Sec. 60.532, a certificate of compliance will be valid for 5 years
from the date of issuance or until a more stringent standard comes into
effect, whichever is sooner.
(i) Renewal of certification. (1) The manufacturer must request
renewal of a model line's certificate of compliance or recertify the
model line every 5 years, or the manufacturer may choose to no longer
manufacture or sell that model line after the expiration date. If the
manufacturer chooses to no longer manufacture that model line, then the
manufacturer must submit a statement to the Administrator to that
effect.
(2) A manufacturer of an affected wood heater model line may apply
to the Administrator for potential renewal of its certificate of
compliance by submitting the material specified in paragraph (b) and
following the procedures specified in paragraph (f) of this section, or
by affirming in writing that the wood heaters in the model line
continue to be similar in all material respects that would affect
emissions to the representative wood heater submitted for testing on
which the original certificate of compliance was based and requesting a
potential waiver from certification testing. The application must
include a copy of the review of the draft application and approval by
the third-party certifier.
(3) If the Administrator grants a renewal of certification, the
Administrator will give written notice to the manufacturer setting
forth the basis for the determination and issue a certification
renewal.
(4) If the Administrator denies the request for a renewal of
certification, the Administrator will give written notice to the
manufacturer setting forth the basis for the determination.
(5) If the Administrator denies the request for a renewal of
certification, the manufacturer and retailer must not manufacture or
sell the previously-certified wood heaters after the expiration date of
the certificate of compliance.
(j) [Reserved]
(k) Recertification. (1) The manufacturer must recertify a model
line whenever any change is made in the design submitted pursuant to
paragraph (b)(2) of this section that affects or is presumed to affect
the particulate matter emission rate for that model line. The
manufacturer of an affected wood heater must apply to the Administrator
for potential recertification by submitting the material specified in
paragraph (b) and following the procedures specified in paragraph (f)
of this section, or by affirming in writing that the change will not
cause wood heaters in the model line to exceed applicable emission
limits and requesting a potential waiver from certification testing.
The application for recertification must be reviewed and approved by
the contracted third-party certifier and a copy of the review and
approval must be included. The Administrator may waive this requirement
upon written request by the manufacturer, if the manufacturer presents
adequate rationale and the Administrator determines that the change may
not reasonably be anticipated to cause wood heaters in the model line
to exceed the applicable emission limits. The granting of such a waiver
does not relieve the manufacturer of any compliance obligations under
this subpart.
(2) Any change in the design tolerances or actual dimensions of any
of the following components (where such components are applicable) is
presumed to affect particulate matter and carbon monoxide emissions and
efficiency if that change exceeds 0.64 cm (\1/
4\ inch) for any linear dimension and 5 percent for any
cross-sectional area relating to air introduction systems and catalyst
bypass gaps unless other dimensions and cross-sectional areas are
previously approved by the Administrator under paragraph (c)(1)(ii) of
this section:

is presumed to affect particulate matter emissions and efficiency:
(i) Refractory/insulation; or
(ii) Door and catalyst bypass gaskets.
(4) A change in the make, model or composition of a catalyst is
presumed to affect particulate matter and carbon monoxide emissions and
efficiency, unless the change has been requested by the heater
manufacturer and has been approved in advance by the Administrator,
based on test data that demonstrate that the replacement catalyst is
equivalent to or better than the original catalyst in terms of
particulate matter emission reduction.
(l) Criteria for revocation of certification. (1) The Administrator
may revoke certification if it is determined that the wood heaters
being manufactured or sold in that model line do not comply with the
requirements of this subpart. Such a determination will be based on all
available evidence, including but not limited to:
(i) Test data from a retesting of the original unit on which the
certification test was conducted or a unit that is similar in all
material respects that would affect emissions;
(ii) A finding that the certification test was not valid. The
finding will be based on problems or irregularities with the
certification test or its documentation, but may be supplemented by
other information;
(iii) A finding that the labeling of the wood heater model line,
the owner's manual or the associated marketing information does not
comply with the requirements of Sec. 60.536;
(iv) Failure by the manufacturer to comply with reporting and
recordkeeping requirements under Sec. 60.537;
(v) Physical examination showing that a significant percentage (as
defined in the quality assurance plan approved pursuant to paragraph

take effect until the manufacturer concerned has been given written
notice by the Administrator setting forth the basis for the proposed
determination and an opportunity to request a hearing under Sec.
60.539.
(m) Quality assurance program. On or after May 16, 2016, for each
certified model line, the manufacturer must conduct a quality assurance
program that satisfies the requirements of paragraphs (m)(1) through
(5) of this section. The quality assurance program requirements of this
paragraph (m) supersede the quality assurance plan requirements
previously specified in Sec. 60.533(o) that was in effect prior to May
15, 2015. The manufacturer of a model line with a compliance
certification under paragraph (h)(1) of this section must conduct a
quality assurance program that satisfies the requirements of this
paragraph (m) by May 16, 2016.
(1) The manufacturer must prepare and operate according to a
quality assurance plan for each certified model line that includes
specific inspection and testing requirements for ensuring that all
units within a model line are similar in all material respects that
would affect emissions to the wood heater submitted for certification
testing and meet the emissions standards in Sec. 60.532.
(2) The quality assurance plan must be approved by the third-party
certifier as part of the certification of conformity process specified
in paragraph (f) of this section.
(3) The quality assurance plan must include regular (at least
annual) unannounced audits by the third-party certifier under ISO-IEC
Standard 17065 to ensure that the manufacturer's quality assurance plan
is being implemented.
(4) The quality assurance plan must include a report for each audit
under ISO-IEC Standard 17065 that fully documents the results of the
audit. The third-party certifier must be authorized and required to
submit all such reports to the Administrator and the manufacturer
within 30 days of the audit. The audit report must identify deviations
from the manufacturer's quality assurance plan and specify the
corrective actions that need to be taken to address each identified
deficiency.
(5) Within 30 days after receiving each audit report, the
manufacturer must report to the third-party certifier and to the
Administrator its corrective actions and responses to any deficiencies
identified in the audit report. No such report is required if an audit
report did not identify any deficiencies.
(n) EPA compliance audit testing. (1)(i) The Administrator may
select by written notice wood heaters or model lines for compliance
audit testing to determine compliance with the emission standards in
Sec. 60.532.
(ii) The Administrator will transmit a written notification of the
selected wood heaters or model line(s) to the manufacturer, which will
include the name and address of the laboratory selected to perform the

have tested, a wood heater or a wood heater from the model line(s)
selected under paragraph (n)(1)(i) of this section in a laboratory
approved under Sec. 60.535. The Administrator may select any approved
test laboratory or federal laboratory for this audit testing.
(ii) The expense of the compliance audit test is the responsibility
of the wood heater manufacturer.
(iii) The test must be conducted using the same test method used to
obtain certification. If the certification test consisted of more than
one particulate matter sampling test method, the Administrator may
direct the manufacturer and test laboratory as to which of these
methods to use for the purpose of audit testing. The Administrator will
notify the manufacturer at least 30 days prior to any test under this
paragraph, and allow the manufacturer and/or his authorized
representatives to observe the test.

[[Page 13709]]

(3) Revocation of certification. (i) If emissions from a wood
heater tested under paragraph (n)(2) of this section exceed the
applicable emission standard by more than 50 percent using the same
test method used to obtain certification, the Administrator will notify
the manufacturer that certification for that model line is suspended
effective 72 hours from the receipt of the notice, unless the
suspension notice is withdrawn by the Administrator. The suspension
will remain in effect until withdrawn by the Administrator, or the date
30 days from its effective date if a revocation notice under paragraph
(n)(3)(ii) of this section is not issued within that period, or the
date of final agency action on revocation, whichever occurs earliest.
(ii)(A) If emissions from a wood heater tested under paragraph
(n)(2) of this section exceed the applicable emission limit, the
Administrator will notify the manufacturer that certification is
revoked for that model line.
(B) A revocation notice under paragraph (n)(3)(ii)(A) of this
section will become final and effective 60 days after the date of
written notification to the manufacturer, unless it is withdrawn, a
hearing is requested under Sec. 60.539(a)(2), or the deadline for
requesting a hearing is extended.
(C) The Administrator may extend the deadline for requesting a
hearing for up to 60 days for good cause.
(D) A manufacturer may extend the deadline for requesting a hearing
for up to 6 months, by agreeing to a voluntary suspension of
certification.
(iii) Any notification under paragraph (n)(3)(i) or (n)(3)(ii) of
this section will include a copy of a preliminary test report from the
approved test laboratory or federal test laboratory. The test
laboratory must provide a preliminary test report to the Administrator
within 14 days of the completion of testing, if a wood heater exceeds
the applicable emission limit in Sec. 60.532. The test laboratory must
provide the Administrator and the manufacturer, within 30 days of the
completion of testing, all documentation pertaining to the test,
including the complete test report and raw data sheets, laboratory
technician notes, and test results for all test runs.
(iv) Upon receiving notification of a test failure under paragraph
(n)(3)(ii) of this section, the manufacturer may request that up to
four additional wood heaters from the same model line be tested at the
manufacturer's expense, at the test laboratory that performed the
emissions test for the Administrator.
(v) Whether or not the manufacturer proceeds under paragraph
(n)(3)(iv) of this section, the manufacturer may submit any relevant
information to the Administrator, including any other test data
generated pursuant to this subpart. The manufacturer must bear the
expense of any additional testing.
(vi) The Administrator will withdraw any notice issued under
paragraph (n)(3)(ii) of this section if tests under paragraph
(n)(3)(iv) of this section show either--
(A) That exactly four additional wood heaters were tested for the
manufacturer and all four met the applicable emission limits; or
(B) That exactly two additional wood heaters were tested for the
manufacturer and each of them met the applicable emission limits and
the average emissions of all three tested heaters (the original audit
heater and the two additional heaters) met the applicable emission
limits.
(vii) If the Administrator withdraws a notice pursuant to paragraph
(n)(3)(vi) of this section, the Administrator will revise the
certification values for the model line based on the test data and
other relevant information. The manufacturer must then revise the model
line's labels and marketing information accordingly.
(viii) The Administrator may withdraw any proposed revocation, if
the Administrator finds that an audit test failure has been rebutted by
information submitted by the manufacturer under paragraph (n)(3)(iv) of
this section and/or (n)(3)(v) of this section or by any other relevant
information available to the Administrator.

within the model line. If one entity licenses a model line to another
entity, each entity's model line must be certified. If an entity
intends to change the name of the entity or the name of the model, the
manufacturer must apply for a new certification 60 days before making
the change.
(2) The manufacturer of each model line must submit the information
required in paragraph (b) of this section and follow either the
certification process in paragraphs (c) through (e) of this section
(for forced-air furnaces) or the certification procedure specified in
paragraph (f) of this section.
(3) Models qualified as meeting the Phase 2 emission levels under
the 2011 EPA hydronic heater partnership agreement are automatically
deemed to have a certificate of compliance for the 2015 particulate
matter emission standards and be valid until the effective date for the
2020 particulate matter emission standards.
(4) Models certified by the New York State Department of
Environment and Conservation to meet the emission levels in Sec.
60.5474(b) are automatically deemed to have a certificate of compliance
for the 2015 particulate matter emission standards and be valid

[[Page 13718]]

until the effective date for the 2020 particulate matter emission
standards.
(5) Models approved by the New York State Energy Research and
Development Authority under the Renewable Heat New York (RHNY) Biomass
Boiler Program are automatically deemed to have a certificate of
compliance for the 2015 particulate matter emission standards and be
valid until the effective date for the 2020 particulate matter emission
standards provided that they comply with the thermal storage
requirements in the RHNY program.
(6) Small forced-air furnace models that are certified under CSA
B415.1-10 (IBR, see Sec. 60.17), by an EPA approved third-party
certifier, to meet the 2016 particulate matter emission level will be
automatically deemed to have a certificate of compliance for the 2016
particulate matter emission standards and be valid until the effective
date for the 2020 particulate matter emission standards.
(7) Large forced-air furnace models that are certified under CSA
B415.1-10 (IBR, see Sec. 60.17), by an EPA approved third-party
certifier, to meet the 2017 particulate matter emission level will be
automatically deemed to have a certificate of compliance for the 2017
particulate matter emission standards and be valid until the effective
date of the 2020 particulate matter emission standards.
(b) Application for a certificate of compliance. Any manufacturer
of an affected residential hydronic heater or forced-air furnace or
other central heater must apply to the Administrator for a certificate

(c) Administrator approval process. (1) The Administrator may issue
a certificate of compliance for a model line if the Administrator
determines, based on all information submitted by

[[Page 13719]]

the applicant and any other relevant information available, that:
(i) A valid certification test demonstrates that the representative
affected central heater complies with the applicable emission standards
in Sec. 60.5474;
(ii) Any tolerances or materials for components listed in paragraph
(k)(2) or (3) of this section that are different from those specified
in those paragraphs may not reasonably be anticipated to cause central
heaters in the model line to exceed the applicable emission limits; and
(iii) The requirements of paragraph (b) of this section have been
met.
(2) The Administrator will deny certification if the Administrator
determines that the criteria in paragraph (c)(1) of this section have
not been satisfied. Upon denying certification under this paragraph,
the Administrator will give written notice to the manufacturer setting
forth the basis for this determination.
(d) Level of compliance certification. The Administrator will issue
the certificate of compliance for the most stringent particulate matter
emission standard that the tested representative central heater meets
under Sec. 60.5474.
(e) Conditional, temporary certificate of compliance. A
conditional, temporary certificate of compliance with the Step 1 p.m.
emission standards may be granted by the Administrator until May 16,
2016 for small or large forced-air furnaces based on the manufacturer's
submittal of a complete certification application meeting all
requirements in Sec. 60.5475(b). The application must include the full
test report by an EPA-approved laboratory and all required compliance
statements by the manufacturer with the exception of a certificate of
conformity by an EPA approved third-party certifier. The conditional,
temporary approval would allow early marketing of forced-air furnaces
as having a conditional, temporary certificate of compliance with the
Step 1 p.m. emission standards until May 16, 2016 or until the
Administrator completes the review of the application, whichever is
earlier.
(f) Third-party certifier-based application process. (1) Any
manufacturer of an affected central heater must apply to the
Administrator for a certificate of compliance for each model line. The
manufacturer must meet the following requirements:
(i) The manufacturer must contract with a third-party certifier for
certification services. The contract must include regular (at least
annual) unannounced audits under ISO-IEC Standard 17065 to ensure that
the manufacturer's quality assurance plan is being implemented. The
contract must also include a report for each audit under ISO-IEC
Standard 17065 that fully documents the results of the audit. The
contract must include authorization and requirement for the third-party
certifier to submit all such reports to the Administrator and the
manufacturer within 30 days of the audit. The audit report must
identify deviations from the manufacturer's quality assurance plan and
specify the corrective actions that need to be taken to address each
identified deficiency.
(ii) The manufacturer must submit the materials specified in
paragraph (b) of this section and a quality assurance plan that meets
the requirements of paragraph (m) of this section to the third-party
certifier. The quality assurance plan must ensure that units within a
model line will be similar in all material respects that would affect
emissions to the wood heater submitted for certification testing, and
it must include design drawings for the model line.
(iii) The manufacturer must apply to the third-party certifier for
a certification of conformity with the applicable requirements of this
subpart for the model line.
(A) After testing by an approved test laboratory is complete,
certification of conformity with the emission standards in Sec.
60.5474 must be performed by the manufacturer's contracted third-party
certifier.
(B) The third-party certifier may 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 central heater meets the applicable emission
limits specified in Sec. 60.5474; and the quality assurance plan is
adequate to ensure that units within the model line will be similar in
all material respects that would affect emissions to the central heater
submitted for certification testing, and that the affected heaters
would meet all applicable requirements of this subpart.
(iv) The manufacturer must then submit to the Administrator an
application for a certificate of compliance that includes the
certification of conformity, quality assurance plan, test report and
all supporting documentation specified in paragraph (b) of this
section.
(v) The submission also must include a statement signed by a
responsible official of the manufacturer or authorized representative
that the manufacturer has complied with and will continue to comply
with all requirements of this subpart for certificate of compliance and
that the manufacturer remains responsible for compliance regardless of
any error by the test laboratory or third-party certifier.
(2) The Administrator will issue to the manufacturer a certificate
of compliance for a model line if it is determined, based on all of the
information submitted in the application for certification and any
other relevant information, that:
(i) A valid certification of conformity has demonstrated that the
representative affected central heater complies with the applicable
emission standards in Sec. 60.5474;
(ii) Any tolerances or materials for components listed in paragraph
(k)(2) or (3) of this section that are different from those specified
in those paragraphs may not be reasonably anticipated to cause central
heaters in the model line to exceed the applicable emission limits;
(iii) The requirements of paragraphs (b) of this section have been
met; and
(iv) A valid certificate of conformity for the model line has been
prepared and submitted.
(3) The Administrator will deny certification if the Administrator
determines that the criteria in paragraph (f)(2) of this section have
not been satisfied. Upon denying certification under this paragraph,
the Administrator will give written notice to the manufacturer setting
forth the basis for the determination.
(g) Waiver from submitting test results. An applicant for
certification may apply for a potential waiver of the requirement to
submit the results of a certification test pursuant to paragraph (b) of
this section, if the central heater meets either of the following
conditions:
(1) The central heaters of the model line are similar in all
material respects that would affect emissions, as defined in Sec.
60.5473 and paragraph (k) of this section, to another model line that
has already been issued a certificate of compliance. A manufacturer
that seeks a waiver of certification testing must identify the model
line that has been certified, and must submit a copy of an agreement
with the owner of the design permitting the applicant to produce
central heaters of that design.
(2) The manufacturer has previously conducted a valid certification
test to demonstrate that the central heaters of the model line meet the
applicable standard specified in Sec. 60.5474.
(h) Certification period. Unless revoked sooner by the
Administrator, a certificate of compliance will be valid

[[Page 13720]]

for 5 years from the date of issuance or until a more stringent
standard comes into effect, whichever is sooner.
(i) Renewal of certification. (1) The manufacturer must renew a
model line's certificate of compliance or recertify the model line
every 5 years, or the manufacturer may choose to no longer manufacture
or sell that model line after the expiration date. If the manufacturer
chooses to no longer manufacture that model line, then the manufacturer
must submit a statement to the Administrator to that effect.
(2) A manufacturer of an affected residential hydronic heater or
forced-air furnace or other central heater may apply to the
Administrator for potential renewal of its certificate of compliance by
submitting the material specified in paragraph (b) and following the
procedures specified in paragraph (f) of this section, or by affirming
in writing that the central heaters in the model line continue to be
similar in all material respects that would affect emissions to the
representative central heater submitted for testing on which the
original certificate of compliance was based and requesting a potential
waiver from certification testing. The application must include a copy
of the review of the draft application and approval by the third-party
certifier.
(3) If the Administrator grants a renewal of certification, the
Administrator will give written notice to the manufacturer setting
forth the basis for the determination and issue a certification
renewal.
(4) If the Administrator denies the request for a renewal of
certification, the Administrator will give written notice to the
manufacturer setting forth the basis for the determination.
(5) If the Administrator denies the request for a renewal of
certification, the manufacturer and retailer must not manufacture or
sell the previously-certified central heaters after the expiration date
of the certificate of compliance.
(j) [Reserved]
(k) Recertification. (1) The manufacturer must recertify a model
line whenever any change is made in the design submitted pursuant to
paragraph (k)(2) of this section that affects or is presumed to affect
the particulate matter emission rate for that model line. The
manufacturer of an affected central heater must apply to the
Administrator for potential recertification by submitting the material
specified in paragraph (b) of this section and following the procedures
specified in paragraph (f) of this section or by affirming in writing
that the change will not cause the central heaters in the model line to
exceed applicable emission limits and requesting a waiver from
certification testing. The application for recertification must be
reviewed and approved by the contracted third-party certifier and a
copy of the review and approval must be included. The Administrator may
waive this requirement upon written request by the manufacturer, if the
manufacturer presents adequate rationale and the Administrator
determines that the change may not reasonably be anticipated to cause
central heaters in the model line to exceed the applicable emission
limits. The granting of such a waiver does not relieve the manufacturer
of any compliance obligations under this subpart.
(2) Any change in the design tolerances of any of the following
components (where such components are applicable) is presumed to affect
particulate matter and carbon monoxide emissions and efficiency if that
change exceeds 0.64 cm (1/4 inch) for any
linear dimension and 5 percent for any cross-sectional area
relating to air introduction systems and catalyst bypass gaps unless
other dimensions and cross-sectional areas are previously approved by
the Administrator under paragraph (c)(1)(ii) of this section:
(i) Firebox: Dimensions;
(ii) Air introduction systems: Cross-sectional area of restrictive
air inlets and outlets, location and method of control;
(iii) Baffles: Dimensions and locations;
(iv) Refractory/insulation: Dimensions and location;
(v) Catalyst: Dimensions and location;
(vi) Catalyst bypass mechanism and catalyst bypass gap tolerances
(when bypass mechanism is in closed position): Dimensions, cross-
sectional area, and location;
(vii) Flue gas exit: Dimensions and location;
(viii) Door and catalyst bypass gaskets: Dimensions and fit;
(ix) Outer thermal shielding and thermal coverings: Dimensions and
location;
(x) Fuel feed system: For central heaters that are designed
primarily to burn wood pellet fuel or wood chips and other central
heaters equipped with a fuel feed system, the fuel feed rate, auger
motor design and power rating, and the angle of the auger to the
firebox; and
(xi) Forced air combustion system: For central heaters so equipped,
the location and horsepower of blower motors and the fan blade size.
(3) Any change in the materials used for the following components
is presumed to affect particulate matter emissions and efficiency:
(i) Refractory/insulation; or
(ii) Door and catalyst bypass gaskets.
(4) A change in the make, model, or composition of a catalyst is
presumed to affect particulate matter and carbon monoxide emissions and
efficiency, unless the change has been requested by the central heater
manufacturer and has been approved in advance by the Administrator,
based on test data that demonstrate that the replacement catalyst is
equivalent to or better than the original catalyst in terms of
particulate matter emission reduction.
(l) Criteria for revocation of certification. (1) The Administrator
may revoke certification of a product line if it is determined that the
central heaters being manufactured or sold in that model line do not
comply with the requirements of this subpart. Such a determination will
be based on all available evidence, including but not limited to:
(i) Test data from retesting of the original unit on which the
certification test was conducted on a unit that is similar in all
material respects that would affect emissions;
(ii) A finding that the certification test was not valid. The
finding will be based on problems or irregularities with the
certification test or its documentation, but may be supplemented by
other information;
(iii) A finding that the labeling of the central heater model line
or the owner's manual or the associated marketing information does not
comply with the requirements of Sec. 60.5478;
(iv) Failure by the manufacturer to comply with the reporting and
recordkeeping requirements of Sec. 60.5479;
(v) Physical examination showing that a significant percentage (as
defined in the quality assurance plan approved pursuant to paragraph
(m) of this section, but no larger than 1 percent) of production units
inspected is not similar in all material respects that would affect
emissions to the representative affected central heater submitted for
certification testing; or
(vi) Failure of the manufacturer to conduct a quality assurance
program in conformity with paragraph (m).
(vii) Failure of the approved laboratory to test the central heater
using the methods specified in Sec. 60.5476.
(2) Revocation of certification under this paragraph (l) of this
section will not take effect until the manufacturer concerned has been
given written notice by the Administrator setting forth the basis for
the proposed determination

[[Page 13721]]

and an opportunity to request a hearing under Sec. 60.5481.
(m) Quality assurance program. On or after May 16, 2016, for each
certified model line, the manufacturer must conduct a quality assurance
program that satisfies the requirements of paragraphs (m)(1) through
(5) of this section.
(1) The manufacturer must prepare and operate according to a
quality assurance plan for each certified model line that includes
specific inspection and testing requirements for ensuring that all
units within a model line are similar in all material respects that
would affect emissions to the central heater submitted for
certification testing and meet the emissions standards in Sec.
60.5474.
(2) The quality assurance plan must be approved by the third-party
certifier as part of the certification of conformity process specified
in paragraph (f) of this section.
(3) The quality assurance plan must include regular (at least
annual) unannounced audits by the third-party certifier under ISO-IEC
Standard 17065 to ensure that the manufacturer's quality assurance plan
is being implemented.
(4) The quality assurance plan must include a report for each audit
under ISO-IEC Standard 17065 that fully documents the results of the
audit. The third-party certifier must be authorized and required to
submit all such reports to the Administrator within 30 days of the
audit. The audit report must identify deviations from the
manufacturer's quality assurance plan and specify the corrective
actions that need to be taken to address each identified deficiency.
(5) Within 30 days after receiving each audit report, the
manufacturer must report to the third-party certifier and to the
Administrator its corrective actions and responses to any deficiencies
identified in the audit report. No such report is required if an audit
report did not identify any deficiencies.
(n) EPA compliance audit testing. (1)(i) The Administrator may
select by written notice central heaters or model lines for compliance
audit testing to determine compliance with the emission standards in
Sec. 60.5474.
(ii) The Administrator will transmit a written notification of the
selected central heaters or model line(s) to the manufacturer, which
will include the name and address of the laboratory selected to perform
the audit test and the model name and serial number of the central
heater(s) or central heater model line(s) selected to undergo audit
testing.
(2)(i) The Administrator may test, or direct the manufacturer to
have tested, the central heater(s) from the model line(s) selected
under paragraph (n)(1)(i) of this section in a laboratory approved

laboratory or federal laboratory for this audit testing.
(ii) The expense of the compliance audit test is the responsibility
of the central heater manufacturer.
(iii) The test must be conducted using the same test method used to
obtain certification. If the certification test consisted of more than
one particulate matter sampling test method, the Administrator may
direct the manufacturer and test laboratory as to which of these
methods to use for the purpose of audit testing. The Administrator will
notify the manufacturer at least 30 days prior to any test under this
paragraph, and allow the manufacturer and/or his authorized
representatives to observe the test.
(3) Revocation of certification. (i) If emissions from a central
heater tested under paragraph (n)(2) of this section exceed the
applicable emission standard by more than 50 percent using the same
test method used to obtain certification, the Administrator will notify
the manufacturer that certification for that model line is suspended
effective 72 hours from the receipt of the notice, unless the
suspension notice is withdrawn by the Administrator. The suspension
will remain in effect until withdrawn by the Administrator, or the date
30 days from its effective date if a revocation notice under paragraph
(n)(3)(ii) of this section is not issued within that period, or the
date of final agency action on revocation, whichever occurs earliest.
(ii)(A) If emissions from a central heater tested under paragraph
(n)(2) of this section exceed the applicable emission limit, the
Administrator will notify the manufacturer that certification is
revoked for that model line.
(B) A notice under paragraph (n)(3)(ii)(A) of this section will
become final and effective 60 days after the date of written
notification to the manufacturer, unless it is withdrawn, a hearing is
requested under Sec. 60.5481(a)(2), or the deadline for requesting a
hearing is extended.
(C) The Administrator may extend the deadline for requesting a
hearing for up to 60 days for good cause.
(D) A manufacturer may extend the deadline for requesting a hearing
for up to 6 months, by agreeing to a voluntary suspension of
certification.
(iii) Any notification under paragraph (n)(3)(i) or (ii) of this
section will include a copy of a preliminary test report from the
approved test laboratory or federal test laboratory. The test
laboratory must provide a preliminary test report to the Administrator
within 14 days of the completion of testing, if a central heater
exceeds the applicable emission limit in Sec. 60.5474. The test
laboratory must provide the Administrator and the manufacturer, within
30 days of the completion of testing, all documentation pertaining to
the test, including the complete test report and raw data sheets,
laboratory technician notes, and test results for all test runs.
(iv) Upon receiving notification of a test failure under paragraph
(n)(3)(ii) of this section, the manufacturer may request that up to
four additional central heaters from the same model line be tested at
the manufacturer's expense, at the test laboratory that performed the
emissions test for the Administrator.
(v) Whether or not the manufacturer proceeds under paragraph
(n)(3)(iv) of this section, the manufacturer may submit any relevant
information to the Administrator, including any other test data
generated pursuant to this subpart. The manufacturer must bear the
expense of any additional testing.
(vi) The Administrator will withdraw any notice issued under
paragraph (n)(3)(ii) of this section if tests under paragraph
(n)(3)(iv) of this section show either--
(A) That exactly four additional central heaters were tested for
the manufacturer and all four met the applicable emission limits; or
(B) That exactly two additional central heaters were tested for the
manufacturer and each of them met the applicable emission limits and
the average emissions of all three tested heaters (the original audit
heater and the two additional heaters) met the applicable emission
limits.
(vii) If the Administrator withdraws a notice pursuant to paragraph
(n)(3)(vi) of this section, the Administrator will revise the
certification values for the model line based on the test data and
other relevant information. The manufacturer must then revise the
labels and marketing information accordingly.
(viii) The Administrator may withdraw any proposed revocation, if
the Administrator finds that an audit test failure has been rebutted by
information submitted by the manufacturer under paragraph (n)(3)(iv) of
this section and/or (n)(3)(v) of this section or by any other relevant
information available to the Administrator.

Sec. 60.5476 What test methods and procedures must I use to determine
compliance with the standards and requirements for certification?

Test methods and procedures specified in this section or in
appendices of this part, except as provided under Sec. 60.8(b), must
be used to determine compliance with the standards and requirements for
certification under Sec. Sec. 60.5474 and 60.5475 and for reporting
carbon monoxide emissions and efficiency. The EPA will post all
approved alternative test methods on the EPA Web site. The manufacturer
or the manufacturer's authorized representative must submit a summary
and the full test report with all supporting information, including
detailed discussion of all anomalies, whether all burn rate categories
were properly achieved, any data not used in the calculations and, for
any test runs not completed, the data that were collected and the
reason that the test run was not completed. The burn rate for the low
burn rate category must be no greater than the rate that an operator
can achieve in home use and no greater than is advertised by the
manufacturer or retailer.
(a) Canadian Standards Administration (CSA) Method B415.1-10,
sections 13.7-13.10 (IBR, see Sec. 60.17), must be used to measure the
thermal efficiency and CO emissions of outdoor and indoor residential
hydronic heaters and forced-air furnaces, except that the burn rates
specified in Method 28WHH must be used for hydronic heaters.
(b) Testing conducted with continuously fed biomass as the fuel(s)
must be conducted according to the relevant section of the ASTM E2618-
13 (IBR, see Sec. 60.17) or adaptations approved by EPA. The EPA will
post all approved alternative test methods on the EPA Web site.
(c)(1) For outdoor and indoor residential hydronic heaters to be
tested under the 2015 particulate matter emission standards in Sec.
60.5474(b)(1), the manufacturer must have an EPA-approved test
laboratory use:
(i) Method 28WHH;
(ii) Method 28WHH PTS;
(iii) ASTM E2618-13 (IBR, see Sec. 60.17) (using crib wood); or
(iv) EN 303-5 (IBR, see Sec. 60.17), only for units sold with
thermal storage.
(2) For outdoor and indoor residential hydronic heaters to be
tested under the 2020 particulate matter emission standards in Sec.
60.5474(b)(2), the manufacturer must have an EPA-approved test
laboratory use:
(i) Method 28WHH;
(ii) Method 28WHH PTS; or
(iii) ASTM E2618-13 (IBR, see Sec. 60.17) (using crib wood).
(3) If the heater is equipped with full or partial heat storage,
the manufacturer, retailer and installer must not sell or install the
heater with less heat storage capacity than is used in the
certification test.
(4) The manufacturer and approved laboratory must make the
following adjustments to the methods listed in paragraphs (a), (c)(1)
and (2) of this section:
(i) For ASTM E2618-13 (IBR, see Sec. 60.17), the burn rate
categories specified in Method 28WHH must be used;
(ii) For EN 303-5 (IBR, see Sec. 60.17), the organic compounds
must be included as part of the PM.
(iii) For ASTM 2618-13 (IBR, see Sec. 60.17) Appendix A1 for full
thermal storage certification tests, the test must use the large scale
as required in the test method unless the manufacturer requests a
variance, in advance of testing, contingent upon measuring flue gas
temperature, oxygen and CO, using a simple electronic spreadsheet
calculator to estimate efficiency and conducting a comparison to the
delivered efficiency to determine if a more detailed examination should
be made.
(5) For particulate matter emission concentrations measured with
ASTM E2515-11 (IBR, see Sec. 60.17), four-inch filters and Teflon
membrane filters or Teflon-coated glass fiber filters may be used.
(6) For all tests conducted using ASTM 2515-11 (IBR, see Sec.
60.17) pursuant to this section, the manufacturer and approved test
laboratory must also measure the first hour of particulate matter
emissions for each test run using a separate filter in one of the two
parallel trains. The manufacturer and approved test laboratory must
report the test results for the first hour separately and also include
them in the total particulate matter emissions per run.
(d)(1) For hydronic heaters subject to the 2020 cord wood
alternative compliance option specified in Sec. 60.5474(b)(3), the
manufacturers must have the approved laboratory conduct cord wood
testing using the test methods listed below:
(i) Method 28WHH;
(ii) Method 28WHH PTS; or
(iii) ASTM E2618-13 (IBR, see Sec. 60.17) (using cord wood).
(2) If the heater is equipped with full or partial heat storage,
the manufacturer, retailer and installer must not sell or install the
heater with less heat storage capacity than is used in the
certification test.
(3) The manufacturer and approved laboratory must make the
following adjustments to the methods listed in (d)(1) of this section:
(i) For ASTM E2618-13 (IBR, see Sec. 60.17), use the burn rate
categories specified in Method 28WHH;
(ii) For all methods, report the results separately per burn rate
category.
(e) For forced-air furnaces, use CSA Method B415.1-10 (IBR, see
Sec. 60.17) to measure the heat output (mmBtu/hr) and particulate
matter emission rate (lb/mmBtu heat output), except use the burn rate
categories in Method 28WHH for the 2020 particulate matter emission
standards. For the 2020 particulate matter emission standards, report
the particulate matter, efficiency and CO emission results separately
per burn rate category.
(f) For affected wood heaters subject to the particulate matter
emission standards, emission concentrations must be measured with ASTM
E2515-11 (IBR, see Sec. 60.17), except for the 2015 certification
tests using EN303-5 (IBR, see Sec. 60.17). As required in paragraph
(c)(4)(ii) of this section, the manufacturer and approved laboratory
must add the organic gases to the PM for EN 303-5. Four-inch filters

least 30 days before the start of testing. The notification of testing
must include the manufacturer's name and physical and email addresses,
the approved test laboratory's name and physical and email addresses,
third-party certifier name, the model name and number (or, if
unavailable, some other way to distinguish between models), and the
dates of testing. The laboratory may substitute certification testing
of another affected central heater on the original date in order to
ensure regular laboratory testing operations.
(i) The approved test laboratory must allow the manufacturer, the
manufacturer's approved third-party certifier, the EPA and delegated
state regulatory agencies to observe certification testing. However,
manufacturers must not involve themselves in the conduct of the test
after the pretest burn has begun.

[[Page 13723]]

Communications between the manufacturer and laboratory or third-party
certifier personnel regarding operation of the central heater must be
limited to written communications transmitted prior to the first
pretest burn of the certification series. During certification tests,
the manufacturer may communicate with laboratory personnel only in
writing and only to notify them that the manufacturer has observed a
deviation from proper test procedures. All communications must be
included in the test documentation required to be submitted pursuant to
Sec. 60.5475(b)(5) and must be consistent with instructions provided
in the owner's manual required under Sec. 60.5478(f), except to the
extent that they address details of the certification tests that would
not be relevant to owners or regulators.

Test Method 28R for Certification and Auditing of Wood Heaters

1.0 Scope and Application

1.1 This test method applies to certification and auditing of
wood-fired room heaters and fireplace inserts.
1.2 The test method covers the fueling and operating protocol
for measuring particulate emissions, as well as determining burn
rates, heat output and efficiency.
1.3 Particulate emissions are measured by the dilution tunnel
method as specified in ASTM E2515-11 Standard Test Method for
Determination of Particulate Matter Emissions Collected in a
Dilution Tunnel (IBR, see Sec. 60.17). Upon request, four-inch
filters may be used. Upon request, Teflon membrane filters or
Teflon-coated glass fiber filters may be used.

2.0 Procedures

2.1 This method incorporates the provisions of ASTM E2780-10
(IBR, see Sec. 60.17) except as follows:
2.1.1 The burn rate categories, low burn rate requirement, and
weightings in Method 28 shall be used.
2.1.2 The startup procedures shall be the same as in Method 28.
2.1.3 Manufacturers shall not specify a smaller volume of the
firebox for testing than the full usable firebox.
2.1.4 Prior to testing, the heater must be operated for a
minimum of 50 hours using a medium burn rate. The conditioning may
be at the manufacturer's facility prior to the certification test.
If the conditioning is at the certification test laboratory, the
pre-burn for the first test can be included as part of the
conditioning requirement.
2.2 Manufacturers may use ASTM E871-82 (reapproved 2013) (IBR,
see Sec. 60.17) as an alternative to the procedures in Method 5H or
Method 28 for determining total weight basis moisture in the
analysis sample of particulate wood fuel.

Test Method 28WHH for Measurement of Particulate Emissions and Heating
Efficiency of Wood-Fired Hydronic Heating Appliances

1.0 Scope and Application

1.1 This test method applies to wood-fired hydronic heating
appliances. The units typically transfer heat through circulation of
a liquid heat exchange media such as water or a water-antifreeze
mixture.
1.2 The test method measures particulate emissions and delivered
heating efficiency at specified heat output rates based on the
appliance's rated heating capacity.
1.3 Particulate emissions are measured by the dilution tunnel
method as specified in ASTM E2515-11 Standard Test Method for
Determination of Particulate Matter Emissions Collected in a
Dilution Tunnel (IBR, see Sec. 60.17). Upon request, four-inch
filters may be used. Upon request, Teflon membrane filters or
Teflon-coated glass fiber filters may be used. Delivered efficiency
is measured by determining the heat output through measurement of
the flow rate and temperature change of water circulated through a
heat exchanger external to the appliance and determining the input
from the mass of dry wood fuel and its higher heating value.
Delivered efficiency does not attempt to account for pipeline loss.
1.4 Products covered by this test method include both
pressurized and non-pressurized heating appliances intended to be
fired with wood. These products are wood-fired hydronic heating
appliances that the manufacturer specifies for indoor or outdoor
installation. They are often connected to a heat exchanger by
insulated pipes and normally include a pump to circulate heated
liquid. They are used to heat structures such as homes, barns and
greenhouses and can heat domestic hot water, spas or swimming pools.
1.5 Distinguishing features of products covered by this standard
include:
1.5.1 Manufacturer specifies for indoor or outdoor installation.
1.5.2 A firebox with an access door for hand loading of fuel.
1.5.3 Typically, an aquastat that controls combustion air supply
to maintain the liquid in the appliance within a predetermined
temperature range provided sufficient fuel is available in the
firebox.
1.5.4 A chimney or vent that exhausts combustion products from
the appliance.
1.6 The values stated are to be regarded as the standard whether
in I-P or SI units. The values given in parentheses are for
information only.

4.0 Summary of Test Method

4.1 Dilution Tunnel. Emissions are determined using the
``dilution tunnel'' method specified in ASTM E2515-11 Standard Test
Method for Determination of Particulate Matter Emissions Collected
in a Dilution Tunnel (IBR, see Sec. 60.17). The flow rate in the
dilution tunnel is maintained at a constant level throughout the
test cycle and accurately measured. Samples of the dilution tunnel
flow stream are extracted at a constant flow rate and drawn through
high efficiency filters. The filters are dried and weighed before
and after the test to determine the emissions catch and this value
is multiplied by the ratio of tunnel flow to filter flow to
determine the total particulate emissions produced in the test
cycle.
4.2 Efficiency. The efficiency test procedure takes advantage of
the fact that this type of appliance delivers heat through
circulation of the heated liquid (water) from the appliance to a
remote heat exchanger and back to the appliance. Measurements of the
water temperature difference as it enters and exits the heat
exchanger along with the measured flow rate allow for an accurate
determination of the useful heat output of the appliance. The input
is determined by weight of the test fuel charge, adjusted for
moisture content, multiplied by the higher heating value. Additional
measurements of the appliance weight and temperature at the
beginning and end of a test cycle are used to correct for heat
stored in the appliance. Overall efficiency (SLM) is determined
using the CSA B415.1-10 (IBR, see Sec. 60.17) stack loss method for
data quality assurance purposes.
4.3 Operation. Appliance operation is conducted on a hot-to-hot
test cycle meaning

[[Page 13729]]

that the appliance is brought to operating temperature and a coal
bed is established prior to the addition of the test fuel charge and
measurements are made for each test fuel charge cycle. The
measurements are made under constant heat draw conditions within
predetermined ranges. No attempt is made to modulate the heat demand
to simulate an indoor thermostat cycling on and off in response to
changes in the indoor environment. Four test categories are used.
These are:
4.3.1 Category I: A heat output of 15 percent or less of
manufacturer's rated heat output capacity.
4.3.2 Category II: A heat output of 16 percent to 24 percent of
manufacturer's rated heat output capacity.
4.3.3 Category III: A heat output of 25 percent to 50 percent of
manufacturer's rated heat output capacity.
4.3.4 Category IV: Manufacturer's rated heat output capacity.

5.0 Significance and Use

5.1 The measurement of particulate matter emission rates is an
important test method widely used in the practice of air pollution
control.
5.1.1 These measurements, when approved by state or federal
agencies, are often required for the purpose of determining
compliance with regulations and statutes.
5.1.2 The measurements made before and after design
modifications are necessary to demonstrate the effectiveness of
design changes in reducing emissions and make this standard an
important tool in manufacturers' research and development programs.
5.2 Measurement of heating efficiency provides a uniform basis
for comparison of product performance that is useful to the
consumer. It is also required to relate emissions produced to the
useful heat production.
5.3 This is a laboratory method and is not intended to be fully
representative of all actual field use. It is recognized that users
of hand-fired, wood-burning equipment have a great deal of influence
over the performance of any wood-burning appliance. Some compromises
in realism have been made in the interest of providing a reliable
and repeatable test method.

11.0 Conditioning

11.1 Prior to testing, the appliance is to be operated for a
minimum of 50 hours using a medium heat draw rate. The conditioning
may be at the manufacturer's facility prior to the certification
test. If the conditioning is at the certification test laboratory,
the pre-burn for the first test can be included as part of the
conditioning requirement. If conditioning is included in pre-burn,
then the appliance shall be aged with fuel meeting the
specifications outlined in sections 12.2 with a moisture content
between 19 and 25 percent on a dry basis. Operate the appliance at a
medium burn rate (Category II or III) for at least 10 hours for
noncatalytic appliances and 50 hours for catalytic appliances.
Record and report hourly flue gas exit temperature data and the
hours of operation. The aging procedure shall be conducted and
documented by a testing laboratory.

12.0 Procedure

12.1 Appliance Installation. Assemble the appliance and parts in
conformance with the manufacturer's written installation
instructions. Clean the flue with an appropriately sized, wire
chimney brush before each certification test series.
12.2 Fuel. Test fuel charge fuel shall be red (Quercus ruba L.)
or white (Quercus alba) oak 19 to 25 percent moisture content on a
dry basis. Piece length shall be 80 percent of the firebox depth
rounded down to the nearest 1 inch (25mm) increment. For example, if
the firebox depth is 46 inches (1168mm) the 4 x 4 piece length would
be 36 inches (46 inches x 0.8 = 36.8 inches rounded down to 36
inches). Pieces are to be placed in the firebox parallel to the
longest firebox dimension. For fireboxes with sloped surfaces that
create a non-uniform firebox length, the piece length shall be
adjusted for each layer based on 80 percent of the length at the
level where the layer is placed. Pieces are to be spaced \3/4\
inches (19 mm) apart on all faces. The first fuel layer may be
assembled using fuel units consisting of multiple 4 x 4s consisting
of single pieces with bottom and side spacers of 3 or more pieces if
needed for a stable layer. The second layer may consist of fuel
units consisting of no more than two pieces with spacers attached on
the bottom and side. The top two layers of the fuel charge must
consist of single pieces unless the fuel charge is only three
layers. In that instance only the top layer must consist of single
units. Three-quarter inch (19 mm) by 1.5 inch (38 mm) spacers shall
be attached to the bottom of piece to maintain a \3/4\ inch (19 mm)
separation. When a layer consists of two or more units of 4 x 4s an
additional \3/4\ inch (19 mm) thick by 1.5 inch (38 mm) wide spacer
shall be attached to the vertical face of each end of one 4 x 4,
such that the \3/4\ inch (19 mm) space will be maintained when two 4
x 4 units or pieces are loaded side by side. In cases where a layer
contains an odd number of 4 x 4s one piece shall not be attached,
but shall have spacers attached in a manner that will provide for
the \3/4\ inch (19 mm) space to be maintained (See Figure 1).
Spacers shall be attached perpendicular to the length of the 4 x 4s
such that the edge of the spacer is 1 0.25 inch from
the end of the 4 x 4s in the previous layers. Spacers shall be red
or white oak and will be attached with either nails (non-
galvanized), brads or oak dowels. The use of kiln-dried wood is not
allowed.
12.2.1 Using a fuel moisture meter as specified in section 6.7
of the test method, determine the fuel moisture for each test fuel
piece used for the test fuel load by averaging at least five fuel
moisture meter readings measured parallel to the wood grain.
Penetration of the moisture meter insulated electrodes for all
readings shall be \1/4\ the thickness of the fuel piece or 19 mm
(\3/4\ in.), whichever is lesser. One measurement from each of three
sides shall be made at approximately 3 inches from each end and the
center. Two additional measurements shall be made centered between
the other three locations. Each individual moisture content reading
shall be in the range of 18 to 28 percent on a dry basis. The
average moisture content of each piece of test fuel shall be in the
range of 19 to 25 percent. It is not required to measure the
moisture content of the spacers. Moisture shall not be added to
previously dried fuel pieces except by storage under high humidity
conditions and temperature up to 100 [deg]F. Fuel moisture shall be
measured within 4 hours of using the fuel for a test.
12.2.2 Firebox Volume. Determine the firebox volume in cubic
feet. Firebox volume shall include all areas accessible through the
fuel loading door where firewood could reasonably be placed up to
the horizontal plane defined by the top of the loading door. A
drawing of the firebox showing front, side and plan views or an
isometric view with interior dimensions shall be provided by the
manufacturer and verified by the laboratory. Calculations for
firebox volume from computer aided design (CAD) software programs
are acceptable and shall be included in the test report if used. If
the firebox volume is calculated by the laboratory the firebox
drawings and calculations shall be included in the test report.
12.2.3 Test Fuel Charge. Test fuel charges shall be determined
by multiplying the firebox volume by 10 pounds (4.54 kg) per ft\3\
(28L), or a higher load density as recommended by the manufacturer's
printed operating instructions, of wood (as used wet weight). Select
the number of pieces of standard fuel that most nearly match this
target weight. This is the standard fuel charge for all tests. For
example, if the firebox loading area volume is 10 ft\3\ (280L) and
the firebox depth is 46 inches (1168 mm), test fuel charge target is
100 lbs (45 kg) minimum and the piece length is 36 inches (914 mm).
If eight 4 x 4s, 36 inches long weigh 105 lbs (48 kg), use 8 pieces
for each test fuel charge. All test fuel charges will be of the same
configuration.
12.3 Sampling Equipment. Prepare the particulate emission
sampling equipment as defined by ASTM E2515-11 Standard Test Method
for Determination of Particulate Matter Emissions Collected in a
Dilution Tunnel (IBR, see Sec. 60.17). Upon request, four-inch
filters may be used. Upon request, Teflon membrane filters or
Teflon-coated glass fiber filters may be used.
12.4 Appliance Startup. The appliance shall be fired with wood
fuel of any species, size and moisture content at the laboratories'
discretion to bring it up to operating temperature. Operate the
appliance until the water is heated to the upper operating control
limit and has cycled at least two times. Then remove all unburned
fuel, zero the scale and verify the scales accuracy using dead
weights.
12.4.1 Pretest Burn Cycle. Reload appliance with oak wood and
allow it to burn down to the specified coal bed weight. The pretest
burn cycle fuel charge weight shall be within 10
percent of the test fuel charge weight. Piece size and length shall
be selected such that charcoalization is achieved by the time the
fuel charge has burned down to the required coal bed weight. Pieces
with a maximum thickness of approximately 2 inches have been found
to be suitable. Charcoalization is a general condition of the test
fuel bed evidenced by an absence of large pieces of burning wood in
the coal bed and the remaining fuel pieces being brittle enough to
be broken into smaller charcoal pieces with a metal poker.
Manipulations to the fuel bed prior to the start of the test run are
to be done to achieve charcoalization while maintaining the desired
heat output rate. During the pre-test burn cycle and at least one
hour prior to starting the test run, adjust water flow to the heat
exchanger to establish the target heat draw for the test. For the
first test run the heat draw rate shall be equal to the
manufacturer's rated heat output capacity.
12.4.1.1 Allowable Adjustments. Fuel addition or subtractions,
and coal bed raking shall be kept to a minimum but are allowed up to
15 minutes prior to the start of the test

[[Page 13731]]

run. For the purposes of this method, coal bed raking is the use of
a metal tool (poker) to stir coals, break burning fuel into smaller
pieces, dislodge fuel pieces from positions of poor combustion, and
check for the condition of charcoalization. Record all adjustments
to and additions or subtractions of fuel, and any other changes to
the appliance operations that occur during pretest ignition period.
During the 15-minute period prior to the start of the test run, the
wood heater loading door shall not be open more than a total of 1
minute. Coal bed raking is the only adjustment allowed during this
period.
12.4.2 Coal Bed Weight. The appliance is to be loaded with the
test fuel charge when the coal bed weight is between 10 percent and
20 percent of the test fuel charge weight. Coals may be raked as
necessary to level the coal bed but may only be raked and stirred
once between 15 to 20 minutes prior to the addition of the test fuel
charge.
12.5 Test Runs. For all test runs, the return water temperature
to the hydronic heater must be equal to or greater than 120 [deg]F.
Aquastat or other heater output control device settings that are
adjustable shall be set using manufacturer specifications, either as
factory set or in accordance with the owner's manual, and shall
remain the same for all burn categories.
Complete a test run in each heat output rate category, as
follows:
12.5.1 Test Run Start. Once the appliance is operating normally
and the pretest coal bed weight has reached the target value per
section 12.4.2, tare the scale and load the full test charge into
the appliance. Time for loading shall not exceed 5 minutes. The
actual weight of the test fuel charge shall be measured and recorded
within 30 minutes prior to loading. Start all sampling systems.
12.5.1.1 Record all water temperatures, differential water
temperatures and water flow rates at time intervals of one minute or
less.
12.5.1.2 Record particulate emissions data per the requirements
of ASTM E2515 (IBR, see Sec. 60.17).
12.5.1.3 Record data needed to determine overall efficiency
(SLM) per the requirements of CSA B415.1-10 (IBR, see Sec. 60.17),
clauses 6.2.1, 6.2.2, 6.3, 8.5.7, 10.4.3 (a), 10.4.3(f), and
13.7.9.3
12.5.1.3.1 Measure and record the test room air temperature in
accordance with the requirements of CSA B415.1-10 (IBR, see Sec.
60.17), clauses 6.2.1, 8.5.7 and 10.4.3 (g).
12.5.1.3.2 Measure and record the flue gas temperature in
accordance with the requirements of CSA B415.1-10 (IBR, see Sec.
60.17), clauses 6.2.2, 8.5.7 and 10.4.3 (f).
12.5.1.3.3 Determine and record the carbon monoxide (CO) and
carbon dioxide (CO2) concentrations in the flue gas in
accordance with CSA B415.1-10 (IBR, see Sec. 60.17), clauses 6.3,
8.5.7 and 10.4.3 (i) and (j).
12.5.1.3.4 Measure and record the test fuel weight per the
requirements of CSA B415.1-10 (IBR, see Sec. 60.17), clauses 8.5.7
and 10.4.3 (h).
12.5.1.3.5 Record the test run time per the requirements of CSA
B415.1-10 (IBR, see Sec. 60.17), clauses 10.4.3 (a).
12.5.1.4 Monitor the average heat output rate on the load side
of the heat exchanger. If the heat output rate gets close to the
upper or lower limit of the target range (5 percent)
adjust the water flow through the heat exchanger to compensate. Make
changes as infrequently as possible while maintaining the target
heat output rate. The first test run shall be conducted at the
Category IV heat output rate to validate that the appliance is
capable of producing the manufacturer's rated heat output capacity.
12.5.2 Test Fuel Charge Adjustment. It is acceptable to adjust
the test fuel charge (i.e., reposition) once during a test run if
more than 60 percent of the initial test fuel charge weight has been
consumed and more than 10 minutes have elapsed without a measurable
(1 lb or 0. 5 kg) weight change while the operating control is in
the demand mode. The time used to make this adjustment shall be less
than 60 seconds.
12.5.3 Test Run Completion. The test run is completed when the
remaining weight of the test fuel charge is 0.0 lb (0.0 kg). End the
test run when the scale has indicated a test fuel charge weight of
0.0 lb (0.0 kg) or less for 30 seconds.
12.5.3.1 At the end of the test run, stop the particulate
sampling train and overall efficiency (SLM) measurements, and record
the run time, and all final measurement values.
12.5.4 Heat Output Capacity Validation. The first test run must
produce a heat output rate that is within 10 percent of the
manufacturer's rated heat output capacity (Category IV) throughout
the test run and an average heat output rate within 5 percent of the
manufacturer's rated heat output capacity. If the appliance is not
capable of producing a heat output within these limits, the
manufacturer's rated heat output capacity is considered not
validated and testing is to be terminated. In such cases, the tests
may be restarted using a lower heat output capacity if requested by
the manufacturer.
12.5.5 Additional Test Runs. Using the manufacturer's rated heat
output capacity as a basis, conduct a test for additional heat
output categories as specified in section 4.3. It is not required to
run these tests in any particular order.
12.5.6 Alternative Heat Output Rate for Category I. If an
appliance cannot be operated in the Category I heat output range due
to stopped combustion, two test runs shall be conducted at heat
output rates within Category II, provided that the completed test
run burn rate is no greater than the burn rate expected in home use.
If this rate cannot be achieved, the test is not valid.
When the alternative heat output rate is used, the weightings
for the weighted averages indicated in Table 2 shall be the average
of the Category I and II weightings and shall be applied to both
Category II results. The two completed runs in Category II will be
deemed to meet the requirement for runs completed in both Category I
and Category II. Appliances that are not capable of operation within
Category II (<25 percent of maximum) cannot be evaluated by this
test method. The test report must include full documentation and
discussion of the attempted runs, completed rums and calculations.
12.5.6.1 Stopped Fuel Combustion. Evidence that an appliance
cannot be operated at a Category I heat output rate due to stopped
fuel combustion shall include documentation of two or more attempts
to operate the appliance in burn rate Category I and fuel combustion
has stopped prior to complete consumption of the test fuel charge.
Stopped fuel combustion is evidenced when an elapsed time of 60
minutes or more has occurred without a measurable (1 lb or 0.5 kg)
weight change in the test fuel charge while the appliance operating
control is in the demand mode. Report the evidence and the reasoning
used to determine that a test in burn rate Category I cannot be
achieved. For example, two unsuccessful attempts to operate at an
output rate of 10 percent of the rated output capacity are not
sufficient evidence that burn rate Category I cannot be achieved.
Note that section 12.5.6 requires that the completed test run burn
rate can be no greater than the burn rate expected in home use. If
this rate cannot be achieved, the test is not valid.
12.5.7 Appliance Overheating. Appliances shall be capable of
operating in all heat output categories without overheating to be
rated by this test method. Appliance overheating occurs when the
rate of heat withdrawal from the appliance is lower than the rate of
heat production when the unit control is in the idle mode. This
condition results in the water in the appliance continuing to
increase in temperature well above the upper limit setting of the
operating control. Evidence of overheating includes: 1 hour or more
of appliance water temperature increase above the upper temperature
set-point of the operating control, exceeding the temperature limit
of a safety control device (independent from the operating control),
boiling water in a non-pressurized system or activation of a
pressure or temperature relief valve in a pressurized system.
12.6 Additional Test Runs. The testing laboratory may conduct
more than one test run in each of the heat output categories
specified in section 4.3.1. If more than one test run is conducted
at a specified heat output rate, the results from at least two-
thirds of the test runs in that heat output rate category shall be
used in calculating the weighted average emission rate (See section
14.1.14). The measurement data and results of all test runs shall be
reported regardless of which values are used in calculating the
weighted average emission rate.

13.5.5 Determine [eta]SLM--Overall Efficiency (SLM) using
Stack Loss

For determination of the average overall thermal efficiency
([eta]SLM) for the test run, use the data collected over
the full test run and the calculations in accordance with CSA
B415.1-10 (IBR, see Sec. 60.17), clause 13.7 except for 13.7.2 (e),
(f), (g), and (h), use the following average fuel properties for
oak: percent C = 50.0, percent H = 6.6, percent O = 43.2, percent
ash = 0.2 percent. The averaging period for determination of
efficiency by the stack loss method allows averaging over 10 minute
time periods for flue gas temperature, flue gas CO2, and
flue gas CO for the determination of the efficiency. However, under
some cycling conditions the ``on'' period may be short relative to
this 10 minute period. For this reason, during cycling operation the
averaging period for these parameters may not be longer than the
burner on period divided by 10. The averaging period need not be
shorter than one minute. During the off period, under cycling
operation, the averaging periods specified may be used. Where short
averaging times are used, however, the averaging period for fuel
consumption may still be at 10 minutes. This average wood
consumption rate shall be applied to all of the smaller time
intervals included.
13.5.5.1 Whenever the CSA B415.1-10 (IBR, see Sec. 60.17)
overall efficiency is found to be lower than the overall efficiency
based on load side measurements, as determined by Eq. 16 of this
method, section 14.1.7 of the test report must include a discussion
of the reasons for this result.

13.6 Weighted Average Emissions and Efficiency

13.6.1 Determine the weighted average emission rate and
delivered efficiency from the individual tests in the specified heat
output categories. The weighting factors (Fi) are derived from an
analysis of ASHRAE bin data which provides details of normal
building heating requirements in terms of percent of design capacity
and time in a particular capacity range--or ``bin''--over the course
of a heating season. The values used in this method represent an
average of data from several cities located in the northern United
States.

13.7 Average Heat Output (Qout-8hr) and Efficiency
(([eta]avg-8hr) for 8 hour burn time.
13.7.1 Units tested under this standard typically require
infrequent fuelling, 8 to 12 hours intervals being typical. Rating
unit's based on an average output sustainable over an 8 hour
duration will assist consumers in appropriately sizing units to
match the theoretical heat demand of their application.
13.7.2 Calculations:
[GRAPHIC] [TIFF OMITTED] TR16MR15.004

[[Page 13734]]

Where:

Y1 = Test duration just above 8 hrs
Y2 = Test duration just below 8 hrs
X1 = Actual load for duration Y1
X2 = Actual load for duration Y2
[eta]del1 = Average delivered efficiency for duration Y1
[eta]del2 = Average delivered efficiency for duration Y2

13.7.2.1 Determine the test durations and actual load for each
category as recorded in Table 1A.
13.7.2.2 Determine the data point that has the nearest duration
greater than 8 hrs.

X1 = Actual load,
Y1 = Test duration, and
[eta]del1 = Average delivered efficiency for this data
point

13.7.2.3 Determine the data point that has the nearest duration
less than 8 hours.
X2 = Actual load,
Y2 = Test duration, and
[eta]del2 = Average delivered efficiency for this data
point

13.7.2.4 Example:

Category Actual Load Duration
[Category Actual Load Duration [eta]del]
------------------------------------------------------------------------
(Btu/Hr) (Hr) (%)
------------------------------------------------------------------------
1 15,000............................................ 10.2 70.0
2 26,000............................................ 8.4 75.5
3 50,000............................................ 6.4 80.1
4 100,000........................................... 4.7 80.9
------------------------------------------------------------------------

Category 2 duration is just above 8 hours, therefore: X1 =
26,000 Btu/hr, [eta]del1 = 75.5% and Y1 = 8.4 hrs
Category 3 duration is just below 8 hours, therefore: X2 =
50,000 Btu/hr, [eta]del2 = 80.1% and Y2 = 6.4 hrs

Qout-8hr = 26,000 + {(8--8.4) x [(50,000--26,000)/(6.4--
8.4)]{time} = 30,800 BTU/hr
[eta]avg-8hr = 75.5 + {(8--8.4) x [(80.1--75.5)/(6.4--
8.4)]{time} = 76.4%

13.8 Carbon Monoxide Emissions

For each minute of the test period, the carbon monoxide emission
rate shall be calculated as:
[GRAPHIC] [TIFF OMITTED] TR16MR15.005

Total CO emissions for each of the three test periods
(CO_1, CO_2, CO_3) shall be
calculated as the sum of the emission rates for each of the 1 minute
intervals.
Total CO emission for the test run, COT, shall be
calculated as the sum of CO_1, CO_2, and
CO_3.

15.0 Precision and Bias

15.1 Precision--It is not possible to specify the precision of
the procedure in Method 28WHH because the appliance operation and
fueling protocols and the appliances themselves produce variable
amounts of emissions and cannot be used to determine reproducibility
or repeatability of this measurement method.
15.2 Bias--No definitive information can be presented on the
bias of the procedure in Method 28WHH for measuring solid fuel
burning hydronic heater emissions because no material having an
accepted reference value is available.

Test Method 28WHH for Certification of Cord Wood-Fired Hydronic Heating
Appliances With Partial Thermal Storage: Measurement of Particulate
Matter (PM) and Carbon Monoxide (CO) Emissions and Heating Efficiency
of Wood-Fired Hydronic Heating Appliances With Partial Thermal Storage

1.0 Scope and Application

1.1 This test method applies to wood-fired hydronic heating
appliances with heat storage external to the appliance. The units
typically transfer heat through circulation of a liquid heat
exchange media such as water or a water-antifreeze mixture.
Throughout this document, the term ``water'' will be used to denote
any of the heat transfer liquids approved for use by the
manufacturer.
1.2 The test method measures PM and CO emissions and delivered
heating efficiency at specified heat output rates referenced against
the appliance's rated heating capacity as specified by the
manufacturer and verified under this test method.
1.3 PM emissions are measured by the dilution tunnel method as
specified in the EPA Method 28WHH and the standards referenced
therein with the exceptions noted in section 12.5.9. Delivered
efficiency is measured by determining the fuel energy input and
appliance output. Heat output is determined through measurement of
the flow rate and temperature change of water circulated through a
heat exchanger external to the appliance and the increase in energy
of the external storage. Heat input is determined from the mass of
dry wood fuel and its higher heating value (HHV). Delivered
efficiency does not attempt to account for pipeline loss.
1.4 Products covered by this test method include both
pressurized and non-pressurized hydronic heating appliances intended
to be fired with wood and for which the manufacturer specifies for
indoor or outdoor installation. The system, which includes the
heating appliance and external storage, is commonly connected to a
heat exchanger by insulated pipes and normally includes a pump to
circulate heated liquid. These systems are used to heat structures
such as homes, barns and greenhouses. They also provide heat for
domestic hot water, spas and swimming pools.
1.5 Distinguishing features of products covered by this standard
include:
1.5.1 The manufacturer specifies the application for either
indoor or outdoor installation.
1.5.2 A firebox with an access door for hand loading of fuel.
1.5.3 Typically an aquastat mounted as part of the appliance
that controls combustion air supply to maintain the liquid in the
appliance within a predetermined temperature range provided
sufficient fuel is available in the firebox. The appliance may be
equipped with other devices to control combustion.
1.5.4 A chimney or vent that exhausts combustion products from
the appliance.
1.5.5 A liquid storage system, typically water, which is not
large enough to accept all of the heat produced when a full load of
wood is burned and the storage system starts a burn cycle at 125
[deg]F.
1.5.6 The heating appliances require external thermal storage
and these units will only be installed as part of a system which
includes thermal storage. The manufacturer specifies the minimum
amount of thermal storage required. However, the storage system

[[Page 13738]]

shall be large enough to ensure that the boiler (heater) does not
cycle, slumber, or go into an off-mode when operated in a Category
III load condition (See section 4.3).
1.6 The values stated are to be regarded as the standard whether
in I-P or SI units. The values given in parentheses are for
information only.

3.1.18 Slumber Mode--This is a mode in which the temperature of
the water in the boiler/heater has exceeded the operating control
limit and the control has changed the boiler/heater fan speed,
dampers, and/or other operating parameters to minimize the heat
output of the boiler/heater.

4.0 Summary of Test Method

4.1 Dilution Tunnel. Emissions are determined using the
``dilution tunnel'' method specified in EPA Method 28WHH and the
standards referenced therein. The flow rate in the dilution tunnel
is maintained at a constant level throughout the test cycle and
accurately measured. Samples of the dilution tunnel flow stream are
extracted at a constant flow rate and drawn through high efficiency
filters. The filters are dried and weighed before and after the test
to determine the emissions collected and this value is multiplied by
the ratio of tunnel flow to filter flow to determine the total
particulate emissions produced in the test cycle.
4.2 Efficiency. The efficiency test procedure takes advantage of
the fact that this type of system delivers heat through circulation
of the heated liquid (water) from the system to a remote heat
exchanger (e.g. baseboard radiators in a room) and back to the
system. Measurements of the cooling water temperature difference as
it enters and exits the test system heat exchanger along with the
measured flow rate allow for an accurate determination of the useful
heat output of the appliance. Also included in the heat output is
the change in the energy content in the storage system during a test
run. Energy input to the appliance during the test run is determined
by weight of the test fuel charge, adjusted for moisture content,
multiplied by the higher heating value. Additional measurements of
the appliance weight and temperature at the beginning and end of a
test cycle are used to correct for heat stored in the appliance.
Overall efficiency (SLM) is determined using the CSA B415.1-10 (IBR,
see Sec. 60.17) stack loss method for data quality assurance
purposes.
4.3 Operation. Four test categories are defined for use in this
method. These are:
4.3.1 Category I: A heat output of 15 percent or less of
manufacturer's rated heat output capacity.
4.3.2 Category II: A heat output of 16 percent to 24 percent of
manufacturer's rated heat output capacity.
4.3.3 Category III: A heat output of 25 percent to 50 percent of
manufacturer's rated heat output capacity.
4.3.4 Category IV: Manufacturer's Rated Heat Output Capacity.
These heat output categories refer to the output from the system by
way of the load heat exchanger installed for the test. The output
from just the boiler/heater part of the system may be higher for all
or part of a test, as part of this boiler/heater output goes to
storage.
For the Category III and IV runs, appliance operation is
conducted on a hot-to-hot test cycle meaning that the appliance is
brought to operating temperature and a coal bed is established prior
to the addition of the test fuel charge and measurements are made
for each test fuel charge cycle. The measurements are made under
constant heat draw conditions within pre-determined ranges. No
attempt is made to modulate the heat demand to simulate an indoor
thermostat cycling on and off in response to changes in the indoor
environment.
For the Category I and II runs, the unit is tested with a ``cold
start.'' At the manufacturer's option, the Category II and III runs
may be waived and it may be assumed that the particulate emission
values and efficiency values determined in the startup, steady-
state, and end phases of Category I are applicable in Categories II
and III for the purpose of determining the annual averages in lb/
mmBtu and g/MJ (See section 13). For the annual average in g/hr, the
length of time for stored heat to be drawn from thermal storage
shall be determined for the test load requirements of the respective
category.
All test operations and measurements shall be conducted by
personnel of the laboratory responsible for the submission of the
test report.

5.0 Significance and Use

5.1 The measurement of particulate matter emission and CO rates
is an important test method widely used in the practice of air
pollution control.
5.1.1 These measurements, when approved by state or federal
agencies, are often required for the purpose of determining
compliance with regulations and statutes.
5.1.2 The measurements made before and after design
modifications are necessary to demonstrate the effectiveness of
design changes in reducing emissions and make this standard an
important tool in manufacturers' research and development programs.

[[Page 13739]]

5.2 Measurement of heating efficiency provides a uniform basis
for comparison of product performance that is useful to the
consumer. It is also required to relate emissions produced to the
useful heat production.
5.3 This is a laboratory method and is not intended to be fully
representative of all actual field use. It is recognized that users
of hand-fired, wood-burning equipment have a great deal of influence
over the performance of any wood-burning appliance. Some compromises
in realism have been made in the interest of providing a reliable
and repeatable test method.

the measurement repeatability shall be better than 15
ppm over the range of CO levels observed in the dilution tunnel.

7.0 Safety

8.0 Sampling, Test Specimens and Test Appliances

8.1 Test specimens shall be supplied as complete appliances, as
described in marketing materials, including all controls and
accessories necessary for installation in the test facility. A full
set of specifications, installation and operating instructions, and
design and assembly drawings shall be provided when the product is
to be placed under certification of a third-party agency. The
manufacturer's written installation and operating instructions are
to be used as a guide in the set-up and testing of the appliance and
shall be part of the test record.
8.2 The size, connection arrangement, and control arrangement
for the thermal storage shall be as specified in the manufacturer's
documentation. It is not necessary to use the specific storage
system that the boiler/heater will be marketed with. However, the
capacity of the system used in the test cannot be greater than that
specified as the minimum allowable for the boiler/heater.
8.3 All system control settings shall be the as-shipped, default
settings. These default settings shall be the same as those
communicated in a document to the installer or end user. These
control settings and the documentation of the control settings as to
be provided to the installer or end user shall be part of the test
record.
8.4 Where the manufacturer defines several alternatives for the
connection and loading arrangement, one shall be defined in the
appliance documentation as the default or standard installation. It
is expected that this will be the configuration for use with a
simple baseboard heating system. This is the configuration to be
followed for these tests. The manufacturer's documentation shall
define the other arrangements as optional or alternative
arrangements.

9.0 Preparation of Test Equipment

9.1 The appliance is to be placed on a scale capable of weighing
the appliance fully loaded with a resolution of 0.2 lb
(0.1 kg).
9.2 The appliance shall be fitted with the type of chimney
recommended or provided by the manufacturer and extending to 15
0.5 feet (4.6 0.15 m) from the upper surface
of the scale. If no flue or chimney system is recommended or
provided by the manufacturer, connect the appliance to a flue of a
diameter equal to the flue outlet of the appliance. The flue section
from the appliance flue collar to 8 0.5 feet above the
scale shall be single wall stove pipe and the remainder of the flue
shall be double wall insulated class A chimney.
9.3 Optional Equipment Use
9.3.1 A recirculation pump may be installed between connections
at the top and bottom of the appliance to minimize thermal
stratification if specified by the manufacturer. The pump shall not
be installed in such a way as to change or affect the flow rate
between the appliance and the heat exchanger.
9.3.2 If the manufacturer specifies that a thermal control valve
or other device be installed and set to control the return water
temperature to a specific set point, the valve or other device shall
be installed and set per the manufacturer's written instructions.
9.4 Prior to filling the boiler/heater with water, weigh and
record the appliance mass.
9.5 Heat Exchanger
9.5.1 Plumb the unit to a water-to-water heat exchanger with
sufficient capacity to draw off heat at the maximum rate
anticipated. Route hoses and electrical cables and instrument wires
in a manner that does not influence the weighing accuracy of the
scale as indicated by placing dead weights on the platform and
verifying the scale's accuracy.
9.5.2 Locate thermocouples to measure the water temperature at
the inlet and outlet of the load side of the heat exchanger.
9.5.3 Install a thermopile (or equivalent instrumentation)
meeting the requirements of section 6.3 to measure the water
temperature difference between the inlet and outlet of the load side
of the heat exchanger
9.5.4 Install a calibrated water flow meter in the heat
exchanger load side supply line. The water flow meter is to be
installed on the cooling water inlet side of the heat exchanger so
that it will operate at the temperature at which it is calibrated.
9.5.5 Place the heat exchanger in a box with 2 in. (50 mm) of
expanded polystyrene (EPS) foam insulation surrounding it to
minimize heat losses from the heat exchanger.
9.5.6 The reported efficiency and heat output rate shall be
based on measurements made on the load side of the heat exchanger.
9.5.7 Temperature instrumentation per section 6.6 shall be
installed in the appliance outlet and return lines. The average of
the outlet and return water temperature on the supply side of the
system shall be considered the average appliance temperature for
calculation of heat storage in the appliance (TFavg and TIavg).
Installation of a water flow meter in the supply side of the system
is optional.

[[Page 13740]]

9.6 Storage Tank. The storage tank shall include a
destratification pump as illustrated in Figure 1. The pump will draw
from the bottom of the tank and return to the top as illustrated.
Temperature sensors (TS1 and TS2 in Figure 1) shall be included to
measure the temperature in the recirculation loop. The valve plan in
Figure 1 allows the tank recirculation loop to operate and the
boiler/heater-to-heat exchanger loop to operate at the same time but
in isolation. This would typically be done before the start of a
test or following completion of a test to determine the end of test
average tank temperature. The nominal flow rate in the storage tank
recirculation loop can be estimated based on pump manufacturers'
performance curves and any significant restriction in the
recirculation loop.
9.7 Fill the system with water. Determine the total weight of
the water in the appliance when the water is circulating. Verify
that the scale indicates a stable weight under operating conditions.
Make sure air is purged properly.

10.0 Calibration and Standardization

10.1 Water Temperature Sensors. Temperature measuring equipment
shall be calibrated before initial use and at least semi-annually
thereafter. Calibrations shall be in compliance with National
Institute of Standards and Technology (NIST) Monograph 175, Standard
Limits of Error.
10.2 Heat Exchanger Load Side Water Flow Meter.
10.2.1 The heat exchanger load side water flow meter shall be
calibrated within the flow range used for the test run using NIST-
traceable methods. Verify the calibration of the water flow meter
before and after each test run and at least once during each test
run by comparing the water flow rate indicated by the flow meter to
the mass of water collected from the outlet of the heat exchanger
over a timed interval. Volume of the collected water shall be
determined based on the water density calculated from section 13,
Eq. 12, using the water temperature measured at the flow meter. The
uncertainty in the verification procedure used shall be 1 percent or
less. The water flow rate determined by the collection and weighing
method shall be within 1 percent of the flow rate indicated by the
water flow meter.
10.3 Scales. The scales used to weigh the appliance and test
fuel charge shall be calibrated using NIST-traceable methods at
least once every 6 months.
10.4 Flue Gas Analyzers--In accordance with CSA B415.1-10 (IBR,
see Sec. 60.17), clause 6.8.

11.0 Conditioning

11.1 Prior to testing, an appliance is to be operated for a
minimum of 50 hours using a medium heat draw rate. The conditioning
may be at the manufacturer's facility prior to the certification
test. If the conditioning is at the certification test laboratory,
the pre-burn for the first test can be included as part of the
conditioning requirement. If conditioning is included in pre-burn,
then the appliance shall be aged with fuel meeting the
specifications outlined in section 12.2 with a moisture content
between 19 and 25 percent on a dry basis. Operate the appliance at a
medium heat output rate (Category II or III) for at least 10 hours
for non-catalytic appliances and 50 hours for catalytic appliances.
Record and report hourly flue gas exit temperature data and the
hours of operation. The aging procedure shall be conducted and
documented by a testing laboratory.

12.0 Procedure

Where:

WSliceWet = weight of the slice before drying in pounds
WSliceDry = weight of the slice after drying in pounds
MCSlice = moisture content of the slice in % dry basis

The average moisture content of the entire test load (MC) shall
be determined using Eq. 6. Each individual slice shall have a
moisture content in the range of 18 percent to 28 percent on a dry
basis. The average moisture content for the test fuel load shall be
in the range of 19 percent to 25 percent. Moisture shall not be
added to previously dried fuel pieces except by storage under high
humidity conditions and temperature up to 100 [deg]F. Fuel moisture
measurement shall begin within 4 hours of using the fuel batch for a
test. Use of a pin-type meter to estimate the moisture content prior
to a test is recommended.
12.2.2 Firebox Volume. Determine the firebox volume in cubic
feet. Firebox volume shall include all areas accessible through the
fuel loading door where firewood could reasonably be placed up to
the horizontal plane defined by the top of the loading door. A
drawing of the firebox showing front, side and plan views or an
isometric view with interior dimensions shall be provided by the
manufacturer and verified by the laboratory. Calculations for
firebox volume from computer aided design (CAD) software programs
are acceptable and shall be included in the test report if used. If
the firebox volume is calculated by the laboratory the firebox
drawings and calculations shall be included in the test report.
12.2.3 Test Fuel charge. Test fuel charges shall be determined
by multiplying the firebox volume by 10 pounds (4.54 kg) per ft\3\
(28L), or a higher load density as recommended by the manufacturer's
printed operating instructions, of wood (as used wet weight). Select
the number of pieces of cord wood that most nearly match this target
weight. However, the test fuel charge cannot be less than the target
of 10 pounds (4.54 kg) per ft\3\ (28L).
12.3 Sampling Equipment. Prepare the particulate emission
sampling equipment as defined by EPA Method 28WHH and the standards
referenced therein.
12.4 Appliance Startup. The appliance shall be fired with wood
fuel of any species, size and moisture content, at the laboratory's
discretion, to bring it up to operating temperature. Operate the
appliance until the water is heated to the upper operating control
limit and has cycled at least two times. Then remove all unburned
fuel, zero the scale and verify the scales accuracy using dead
weights.
12.4.1 Startup Procedure for Category III and IV Test Runs,
``Hot-to-Hot.''
12.4.1.1 Pretest t Burn Cycle. Following appliance startup
(section 12.4), reload appliance with oak cord wood and allow it to
burn down to the specified coal bed weight. The pre-test burn cycle
fuel charge

[[Page 13741]]

weight shall be within 10 percent of the test fuel
charge weight. Piece size and length shall be selected such that
charcoalization is achieved by the time the fuel charge has burned
down to the required coal bed weight. Pieces with a maximum
thickness of approximately 2 inches have been found to be suitable.
Charcoalization is a general condition of the test fuel bed
evidenced by an absence of large pieces of burning wood in the coal
bed and the remaining fuel pieces being brittle enough to be broken
into smaller charcoal pieces with a metal poker. Manipulations to
the fuel bed prior to the start of the test run are to be done to
achieve charcoalization while maintaining the desired heat output
rate. During the pre-test burn cycle and at least one hour prior to
starting the test run, adjust water flow to the heat exchanger to
establish the target heat draw for the test. For the first test run
the heat draw rate shall be equal to the manufacturer's rated heat
output capacity.
12.4.1.2 Allowable Adjustments. Fuel addition or subtractions,
and coal bed raking shall be kept to a minimum but are allowed up to
15 minutes prior to the start of the test run. For the purposes of
this method, coal bed raking is the use of a metal tool (poker) to
stir coals, break burning fuel into smaller pieces, dislodge fuel
pieces from positions of poor combustion, and check for the
condition of charcoalization. Record all adjustments to and
additions or subtractions of fuel, and any other changes to the
appliance operations that occur during pretest ignition period.
During the 15-minute period prior to the start of the test run, the
wood heater loading door shall not be open more than a total of 1
minute. Coal bed raking is the only adjustment allowed during this
period.
12.4.1.3 Coal Bed Weight. The appliance is to be loaded with the
test fuel charge when the coal bed weight is between 10 percent and
20 percent of the test fuel charge weight. Coals may be raked as
necessary to level the coal bed but may only be raked and stirred
once between 15 to 20 minutes prior to the addition of the test fuel
charge.
12.4.1.4 Storage. The Category III and IV test runs may be done
either with or without the thermal storage. If thermal storage is
used, the initial temperature of the storage must be 125 [deg]F or
greater at the start of the test. The storage may be heated during
the pre-test burn cycle or it may be heated by external means. If
thermal storage is used, prior to the start of the test run, the
storage tank destratification pump, shown in Figure 1, shall be
operated until the total volume pumped exceeds 1.5 times the tank
volume and the difference between the temperature at the top and
bottom of the storage tank (TS1 and TS2) is
less than 1 [deg]F. These two temperatures shall then be recorded to
determine the starting average tank temperature. The total volume
pumped may be based on the nominal flow rate of the destratification
pump (See section 9.6). If the Category III and IV runs are done
with storage, it is recognized that during the last hour of the pre-
burn cycle the storage tank must be mixed to achieve a uniform
starting temperature and cannot receive heat from the boiler/heater
during this time. During this time period, the boiler/heater might
cycle or go into a steady reduced output mode. (Note--this would
happen, for example, in a Category IV run if the actual maximum
output of the boiler/heater exceed the manufacturer's rated output.)
A second storage tank may be used temporarily to enable the boiler/
heater to operate during this last hour of the pre-burn period as it
will during the test period. The temperature of this second storage
tank is not used in the calculations but the return water to the
boiler/heater (after mixing device if used) must be 125 [deg]F or
greater.
12.4.2 Startup Procedure for Category I and II Test Runs,
``Cold-to-Cold.''
12.4.2.1 Initial Temperatures. This test shall be started with
both the boiler/heater and the storage at a minimum temperature of
125[deg]F. The boiler/heater maximum temperature at the start of
this test shall be 135 [deg]F. The boiler/heater and storage may be
heated through a pre-burn or it may be heated by external means.
12.4.2.2 Firebox Condition at Test Start. Prior to the start of
this test remove all ash and charcoal from the combustion
chamber(s). The loading of the test fuel and kindling should follow
the manufacturer's recommendations, subject to the following
constraints: Up to 10 percent kindling and paper may be used which
is in addition to the fuel load. Further, up to 10 percent of the
fuel load (i.e., included in the 10 lb/ft\3\) may be smaller than
the main fuel. This startup fuel shall still be larger than 2
inches.
12.4.2.3 Storage. The Category I and II test runs shall be done
with thermal storage. The initial temperature of the storage must be
125 [deg]F or greater at the start of the test. The storage may be
heated during the pre-test burn cycle or it may be heated by
external means. Prior to the start of the test run, the storage tank
destratification pump, shown in Figure 1, shall be operated until
the total volume pumped exceeds 1.5 times the tank volume and the
difference between the temperature at the top and bottom of the
storage tank (TS1 and TS2) is less than 1
[deg]F. These two temperatures shall then be recorded to determine
the starting average tank temperature. The total volume pumped may
be based on the nominal flow rate of the destratification pump (See
section 9.6).
12.5 Test Runs. For all test runs, the return water temperature
to the hydronic heater must be equal to or greater than 120 [deg]F
(this is lower than the initial tank temperature to allow for any
pipeline losses). Where the storage system is used, flow of water
from the boiler/heater shall be divided between the storage tank and
the heat exchanger such that the temperature change of the
circulating water across the heat exchanger shall be 30 5 [deg]F, averaged over the entire test run. This is typically
adjusted using the system valves.
Complete a test run in each heat output rate category, as
follows:
12.5.1 Test Run Start. For Category III and IV runs: Once the
appliance is operating normally and the pretest coal bed weight has
reached the target value per section 12.4.1, tare the scale and load
the full test charge into the appliance. Time for loading shall not
exceed 5 minutes. The actual weight of the test fuel charge shall be
measured and recorded within 30 minutes prior to loading. Start all
sampling systems.
For Category I and II runs: Once the appliance has reached the
starting temperature, tare the scale and load the full test charge,
including kindling into the appliance. The actual weight of the test
fuel charge shall be measured and recorded within 30 minutes prior
to loading. Light the fire following the manufacturer's written
normal startup procedure. Start all sampling systems.
12.5.1.1 Record all water temperatures, differential water
temperatures and water flow rates at time intervals of one minute or
less.
12.5.1.2 Record particulate emissions data per the requirements
of EPA Method 28WHH and the standards referenced therein.
12.5.1.3 Record data needed to determine overall efficiency
(SLM) per the requirements of CSA B415.1-10 (IBR, see Sec. 60.17)
clauses 6.2.1, 6.2.2, 6.3, 8.5.7, 10.4.3(a), 10.4.3(f), and 13.7.9.3
12.5.1.3.1 Measure and record the test room air temperature in
accordance with the requirements of CSA B415.1-10 (IBR, see Sec.
60.17), clauses 6.2.1, 8.5.7 and 10.4.3(g).
12.5.1.3.2 Measure and record the flue gas temperature in
accordance with the requirements of CSA B415.1-10 (IBR, see Sec.
60.17), clauses 6.2.2, 8.5.7 and 10.4.3(f).
12.5.1.3.3 Determine and record the carbon monoxide (CO) and
carbon dioxide (CO2) concentrations in the flue gas in
accordance with CSA B415.1-10 (IBR, see Sec. 60.17), clauses 6.3,
8.5.7 and 10.4.3(i) and (j).
12.5.1.3.4 Measure and record the test fuel weight per the
requirements of CSA B415.1-10 (IBR, see Sec. 60.17), clauses 8.5.7
and 10.4.3(h).
12.5.1.3.5 Record the test run time per the requirements of CSA
B415.1-10 (IBR, see Sec. 60.17), clause 10.4.3(a).
12.5.1.3.6 Record and document all settings and adjustments, if
any, made to the boiler/heater as recommended/required by
manufacturer's instruction manual for different combustion
conditions or heat loads. These may include temperature setpoints,
under and over-fire air adjustment, or other adjustments that could
be made by an operator to optimize or alter combustion. All such
settings shall be included in the report for each test run.
12.5.1.4 Monitor the average heat output rate on the load side
of the heat exchanger based on water temperatures and flow. If the
heat output rate over a 10 minute averaging period gets close to the
upper or lower limit of the target range (5 percent),
adjust the water flow through the heat exchanger to compensate. Make
changes as infrequently as possible while maintaining the target
heat output rate. The first test run shall be conducted at the
Category IV heat output rate to validate that the appliance is
capable of producing the manufacturer's rated heat output capacity.
12.5.2 Test Fuel Charge Adjustment. It is acceptable to adjust
the test fuel charge (i.e., reposition) once during a test run if
more than 60 percent of the initial test fuel charge weight has been
consumed and more than 10

[[Page 13742]]

minutes have elapsed without a measurable (1 lb or 0.5 kg) weight
change while the operating control is in the demand mode. The time
used to make this adjustment shall be less than 60 seconds.
12.5.3 Test Run Completion. For the Category III and IV, ``hot-
to-hot'' test runs, the test run is completed when the remaining
weight of the test fuel charge is 0.0 lb (0.0 kg). (WFuelBurned =
Wfuel) End the test run when the scale has indicated a test fuel
charge weight of 0.0 lb (0.0 kg) or less for 30 seconds.
For the Category I and II ``cold-to-cold'' test runs, the test
run is completed; and the end of a test is defined at the first
occurrence of any one of the following:
(a) The remaining weight of the test fuel charge is less than 1
percent of the total test fuel weight (WFuelBurned > 0.99 [middot]
Wfuel);
(b) The automatic control system on the boiler/heater switches
to an off mode. In this case, the boiler/heater fan (if used) is
typically stopped and all air flow dampers are closed by the control
system. Note that this off mode cannot be an ``overheat'' or
emergency shutdown which typically requires a manual reset; or
(c) If the boiler/heater does not have an automatic off mode:
After 90 percent of the fuel load has been consumed and the scale
has indicated a rate of change of the test fuel charge of less than
1.0 lb/hr for a period of 10 minutes or longer. Note--this is not
considered ``stopped fuel combustion,'' See section 12.5.6.1.
12.5.3.1 At the end of the test run, stop the particulate
sampling train and overall efficiency (SLM) measurements, and record
the run time, and all final measurement values.
12.5.3.2 At the end of the test run, continue to operate the
storage tank destratification pump until the total volume pumped
exceeds 1.5 times the tank volume. The maximum average of the top
and bottom temperatures measured after this time may be taken as the
average tank temperature at the end of the tests (TFSavg, See
section 13.1). The total volume pumped may be based on the nominal
flow rate of the destratification pump (See section 9.6).
12.5.3.3 For the Category I and II test runs, there is a need to
determine the energy content of the unburned fuel remaining in the
chamber if the remaining mass in the chamber is greater than 1
percent of the test fuel weight. Following the completion of the
test, as soon as safely practical, this remaining fuel is removed
from the chamber, separated from the remaining ash and weighed. This
separation could be implemented with a slotted ``scoop'' or similar
tool. A \1/4\ inch opening size in the separation tool shall be used
to separate the ash and charcoal. This separated char is assigned a
heating value of 12,500 Btu/lb.
12.5.4 Heat Output Capacity Validation. The first test run must
produce a heat output rate that is within 10 percent of the
manufacturer's rated heat output capacity (Category IV) throughout
the test run and an average heat output rate within 5 percent of the
manufacturer's rated heat output capacity. If the appliance is not
capable of producing a heat output within these limits, the
manufacturer's rated heat output capacity is considered not
validated and testing is to be terminated. In such cases, the tests
may be restarted using a lower heat output capacity if requested by
the manufacturer. Alternatively, during the Category IV run, if the
rated output cannot be maintained for a 15 minute interval, the
manufacturer may elect to reduce the rated output to match the test
and complete the Category IV run on this basis. The target outputs
for Categories I, II, and III shall then be recalculated based on
this change in rated output capacity.
12.5.5 Additional Test Runs. Using the manufacturer's rated heat
output capacity as a basis, conduct a test for additional heat
output categories as specified in section 4.3. It is not required to
run these tests in any particular order.
12.5.6 Alternative Heat Output Rate for Category I. If an
appliance cannot be operated in the Category I heat output range due
to stopped combustion, two test runs shall be conducted at heat
output rates within Category II. When this is the case, the
weightings for the weighted averages indicated in section 14.1.15
shall be the average of the Category I and II weighting's and shall
be applied to both Category II results. Appliances that are not
capable of operation within Category II (<25 percent of maximum)
cannot be evaluated by this test method.
12.5.6.1 Stopped Fuel Combustion. Evidence that an appliance
cannot be operated at a Category I heat output rate due to stopped
fuel combustion shall include documentation of two or more attempts
to operate the appliance in heat output rate Category I and fuel
combustion has stopped prior to complete consumption of the test
fuel charge. Stopped fuel combustion is evidenced when an elapsed
time of 60 minutes or more has occurred without a measurable (1 lb
or 0.5 kg) weight change in the test fuel charge while the appliance
operating control is in the demand mode. Report the evidence and the
reasoning used to determine that a test in heat output rate Category
I cannot be achieved. For example, two unsuccessful attempts to
operate at an output rate of 10 percent of the rated output capacity
are not sufficient evidence that heat output rate Category I cannot
be achieved.
12.5.7 Appliance Overheating. Appliances with their associated
thermal storage shall be capable of operating in all heat output
categories without overheating to be rated by this test method.
Appliance overheating occurs when the rate of heat withdrawal from
the appliance is lower than the rate of heat production when the
unit control is in the idle mode. This condition results in the
water in the appliance continuing to increase in temperature well
above the upper limit setting of the operating control. Evidence of
overheating includes: 1 hour or more of appliance water temperature
increase above the upper temperature set-point of the operating
control, exceeding the temperature limit of a safety control device
(independent from the operating control--typically requires manual
reset), boiling water in a non-pressurized system or activation of a
pressure or temperature relief valve in a pressurized system.
12.5.8 Option to Eliminate Tests in Category II and III.
Following successful completion of a test run in Category I, the
manufacturer may eliminate the Category II and III tests. For the
purpose of calculating the annual averages for particulates and
efficiency, the values obtained in the Category I run shall be
assumed to apply also to Category II and Category III. It is
envisioned that this option would be applicable to systems which
have sufficient thermal storage such that the fuel load in the
Category I test can be completely consumed without the system
reaching its upper operating temperature limit. In this case, the
boiler/heater would likely be operating at maximum thermal output
during the entire test and this output rate may be higher than the
manufacturer's rated heat output capacity. The Category II and III
runs would then be the same as the Category I run. It may be assumed
that the particulate emission values and efficiency values
determined in the startup, steady-state, and end phases of Category
I are applicable in Categories II and III, for the purpose of
determining the annual averages in lb/mmBtu and g/MJ (See section
13). For the annual average in g/hr, the length of time for stored
heat to be drawn from thermal storage shall be determined for the
test load requirements of the respective category.
12.5.9 Modification to Measurement Procedure in EPA Method 28WHH
to Determine Emissions Separately During the Startup, Steady-State
and End Phases. With one of the two particulate sampling trains
used, filter changes shall be made at the end of the startup phase
and the steady-state phase (See section 3.0). This shall be done to
determine the particulate emission rate and particulate emission
index for the startup, steady-state, and end phases individually.
For this one train, the particulates measured during each of these
three phases shall be added together to also determine the
particulate emissions for the whole run.
12.5.10 Modification to Measurement Procedure in EPA Method
28WHH and the Standards Referenced therein on Averaging Period for
Determination of Efficiency by the Stack Loss Method. The methods
currently defined in Method 28WHH allow averaging over 10-minute
time periods for flue gas temperature, flue gas CO2, and
flue gas CO for the determination of the efficiency with the stack
loss method. However, under some cycling conditions the ``on''
period may be short relative to this 10-minute period. For this
reason, during cycling operation the averaging period for these
parameters may not be longer than the burner on period divided by
10. The averaging period need not be shorter than one minute. During
the off period, under cycling operation, averaging periods as
specified in EPA Method 28WHH and the standards referenced therein,
may be used. Where short averaging times are used, however, the
averaging period for fuel consumption may still be at 10 minutes.
This average wood consumption rate shall be applied to all of the
smaller time intervals included.
12.6 Additional Test Runs. The testing laboratory may conduct
more than one test run in each of the heat output categories

[[Page 13743]]

specified in section 4.3. If more than one test run is conducted at
a specified heat output rate, the results from at least two-thirds
of the test runs in that heat output rate category shall be used in
calculating the weighted average emission rate. The measurement data
and results of all test runs shall be reported regardless of which
values are used in calculating the weighted average emission rate.

13.6.4 Determine delivered efficiency as:
[GRAPHIC] [TIFF OMITTED] TR16MR15.014

13.6.5 Determine [eta]SLM--Overall Efficiency, also
known as Stack Loss Efficiency, using stack loss method (SLM).
For determination of the average overall thermal efficiency
([eta]SLM) for the test run, use the data collected over
the full test run and the calculations in accordance with CSA
B415.1-10 (IBR, see Sec. 60.17), clause 13.7 except for 13.7.2(e),
(f), (g), and (h), use the following average fuel properties for
oak: %C = 50.0, %H = 6.6, %O = 43.2, %Ash = 0.2.
13.6.5.1 Whenever the CSA B415.1-10 (IBR, see Sec. 60.17)
overall efficiency is found to be lower than the overall efficiency
based on load side measurements, as determined by Eq. 22 of this
method, section 14.1.7 of the test report must include a discussion
of the reasons for this result. For a test where the CSA B415.1-10
overall efficiency SLM is less than 2 percentage points lower than
the overall efficiency based on load side measurements, the
efficiency based on load side measurements shall be considered
invalid. [Note on the rationale for the 2 percentage points limit.
The SLM method does not include boiler/heater jacket losses and, for
this reason, should provide an efficiency which is actually higher
than the efficiency based on the energy input and output
measurements or ``delivered efficiency.'' A delivered efficiency
that is higher than the efficiency based on the SLM could be
considered suspect. A delivered efficiency greater than 2 percentage
points higher than the efficiency based on the SLM, then, clearly
indicates a measurement error.]
13.6.6 Carbon Monoxide Emissions
For each minute of the test period, the carbon monoxide emission
rate shall be calculated as:
[GRAPHIC] [TIFF OMITTED] TR16MR15.015

Total CO emissions for each of the three test periods
(CO_1, CO_2, CO_3) shall be
calculated as the sum of the emission rates for each of the 1-minute
intervals. Total CO emission for the test run, COT, shall
be calculated as the sum of CO_1, CO_2, and
CO_3.
13.7 Weighted Average Emissions and Efficiency.
13.7.1 Determine the weighted average emission rate and
delivered efficiency from the individual tests in the specified heat
output categories. The weighting factors (Fi) are derived
from an analysis of ASHRAE bin data which provides details of normal
building heating requirements in terms of percent of design capacity
and time in a particular capacity range--or ``bin''--over the course
of a heating season. The values used in this method represent an
average of data from several cities located in the northern United
States.
[GRAPHIC] [TIFF OMITTED] TR16MR15.016

[[Page 13746]]

If, as discussed in section 12.5.8, the option to eliminate
tests in Category II and III is elected, the values of efficiency
and particulate emission rate as measured in Category I, shall be
assigned also to Category II and III for the purpose of determining
the annual averages.

14.1.20 Raw data, calibration records, and other relevant
documentation shall be retained by the laboratory for a minimum of 7

15.0 Precision and Bias

15.1 Precision--It is not possible to specify the precision of
the procedure in this test method because the appliance operation
and fueling protocols and the appliances themselves produce variable
amounts of emissions and cannot be used to determine reproducibility
or repeatability of this test method.
15.2 Bias--No definitive information can be presented on the
bias of the procedure in this test method for measuring solid fuel
burning hydronic heater emissions because no material having an
accepted reference value is available.

16.0 Keywords

16.1 Solid fuel, hydronic heating appliances, wood-burning
hydronic heaters, partial thermal storage.

should be written specific to the model and design of the wood
heater. The following instructions are composed of generic
descriptions and texts.
(b) If manufacturers choose to use the language provided in the
example, the portion in italics should be revised as appropriate.
Any manufacturer electing to use the EPA example language will be
considered to be in compliance with owner's manual requirements
provided that the particular language is printed in full with only
such changes as are necessary to ensure accuracy.
Example language is not provided for certain topics, since these
areas are generally heater specific. For these topics, manufacturers
should develop text that is specific to the proper operation and
maintenance of their particular products.

2.3.1 Wood Heater Description and Compliance Status

Owner's manuals must include:
(a) Manufacturer and model;
(b) Compliance status (2015 standard, 2016 standard, 2017
standard, 2020 standard, crib wood standard or cord wood alternative
standard, last allowable sell date, etc.); and

(c) Achieving catalyst light-off when refueling.
2.3.5.1 No example text is supplied for describing operation of
catalyst bypass mechanisms (Item 2.3.5(a) of this appendix) since
these are typically stove-specific. Manufacturers must provide
instructions specific to their model describing:
(1) Bypass position during startup;
(2) Bypass position during normal operation; and
(3) Bypass position during reloading.
Exhibit 4--Example Text for Item 2.3.5(b) of this appendix:
``The temperature in the stove and the gases entering the
combustor must be raised to between 500[deg] to 700 [deg]F for
catalytic activity to be initiated. During the startup of a cold
stove, a medium to high firing rate must be maintained for about 20
minutes. This ensures that the stove, catalyst, and fuel are all
stabilized at proper operating temperatures. Even though it is
possible to have gas temperatures reach 600 [deg]F within 2 to 3
minutes after a fire is started, if the fire is allowed to die down
immediately, it may go out or the combustor may stop working. Once
the combustor starts working, heat generated in it by burning the
smoke will keep it working.''
Exhibit 5--Example Text for Item 2.3.5(c) of this appendix:
``REFUELING: During the refueling and rekindling of a cool fire,
or a fire that has burned down to the charcoal phase, operate the
stove at a medium to high firing rate for about 10 minutes to ensure
that the catalyst reaches approximately 600 [deg]F.''

2.3.6 Catalyst Monitoring

Owner's manuals must include:
(a) Recommendation to visually inspect combustor at least three
times during the heating season;
(b) Discussion on expected combustor temperatures for monitor-
equipped units; and
(c) Suggested monitoring and inspection techniques and
importance of ensuring catalyst is operating properly.
Exhibit 6--Example Text covering 2.3.6(a), (b) and (c) of this
appendix:
``It is important to periodically monitor the operation of the
catalytic combustor to ensure that it is functioning properly and to
determine when it needs to be replaced. A non-functioning combustor
will result in a loss of heating efficiency, and an increase in
creosote and emissions. Following is a list of items that should be
checked on a periodic basis:
Combustors should be visually inspected at least three
times during the heating season to determine if physical degradation
has occurred. Actual removal of the combustor is not recommended
unless more detailed inspection is warranted because of decreased
performance. If any of these conditions exists, refer to Catalyst
Troubleshooting section of this owner's manual.
This catalytic (or hybrid) heater is equipped with a
temperature probe to monitor catalyst operation. Properly
functioning combustors typically maintain temperatures in excess of
500 [deg]F, and often reach temperatures in excess of 1,000 [deg]F.
If catalyst temperatures are not in excess of 500 [deg]F, refer to
Catalyst Troubleshooting section of this owner's manual.
You can get an indication of whether the catalyst is
working by comparing the amount of smoke leaving the chimney when
the smoke is going through the combustor and catalyst light-off has
been achieved, to the amount of smoke leaving the chimney when the
smoke is not routed through the combustor (bypass mode).
Step 1--Light stove in accordance with instructions in section
3.3.5.
Step 2--With smoke routed through the catalyst, go outside and
observe the emissions leaving the chimney.
Step 3--Engage the bypass mechanism and again observe the
emissions leaving the chimney.
Significantly more smoke will be seen when the exhaust is not
routed through the combustor (bypass mode).''

2.3.7 Catalyst Troubleshooting

The owner's manual must provide clear descriptions of symptoms
and remedies to common combustor problems and importance. It is
recommended that photographs of catalyst peeling, plugging, thermal
cracking, mechanical cracking, and masking be included in the manual
to aid the consumer in identifying problems and to provide direction
for corrective action.

2.3.8 Catalyst Replacement

The owner's manual must provide clear step-by-step instructions
on how to remove and replace the catalytic combustor. The section
should include diagrams and/or photographs.

2.3.9 Wood Heater Proper Operation and Maintenance

The owner's manual must provide clear descriptions of symptoms
and remedies to

[[Page 13753]]

common heater problems and importance. The owner's manual
information must be adequate to enable consumers to achieve optimal
emissions performance. Such information must be consistent with the
operating instructions provided by the manufacturer to the approved
test laboratory for operating the wood heater during certification
testing, except for details of the certification test that would not
be relevant to the user.
Owner's manual must include:
(a) Recommendations about building and maintaining a fire,
especially for cold starts and the effectiveness of the top-down
approach for starting fires;
(b) Instruction on proper use of air controls, including how to
establish good combustion and how to ensure good combustion at the
lowest burn rate for which the heater is warranted;
(c) Ash removal and disposal;
(d) Instruction replacement of gaskets, air tubes and other
parts that are critical to the emissions performance of the unit,
and other maintenance and repair instructions;
(e) Warning against overfiring; and
(f) Suggested monitoring and inspection techniques and
importance of ensuring heater is operating properly, including
ensuring visible emissions are minimized.
2.3.9.1 No example text is supplied for 2.3.9(a), (b), (d) and
(f) of this appendix since these items are model specific.
Manufacturers should provide detailed instructions on building and
maintaining a fire including selection of fuel pieces, fuel quantity
and stacking arrangement. Manufacturers should also provide
instruction on proper air settings (both primary and secondary) for
attaining minimum and maximum heat outputs and any special
instructions for operating thermostatic controls. Step-by-step
instructions on inspection and replacement of gaskets should also be
included. Manufacturers should provide diagrams and/or photographs
to assist the consumer. Gasket type and size should be specified.
Exhibit 7--Example Text for Item 2.3.9(c) of this appendix:
``Whenever ashes get 3 to 4 inches deep in your firebox or ash
pan, and when the fire has burned down and cooled, remove excess
ashes. Leave an ash bed approximately 1 inch deep on the firebox
bottom to help maintain a hot charcoal bed.''
``Ashes should be placed in a metal container with a tight-
fitting lid. The closed container of ashes should be placed on a
noncombustible floor or on the ground, away from all combustible
materials, pending final disposal. The ashes should be retained in
the closed container until all cinders have thoroughly cooled.''
Exhibit 8--Example Text covering Item 2.3.9(e) of this appendix:

``DO NOT OVERFIRE THIS HEATER''

``Attempts to achieve heat output rates that exceed heater
design specifications can result in permanent damage to the heater
and to the catalytic combustor if so equipped.''

2.3.10 Wood Heater Installation, Including Stack Height, Heater
Locations and Achieving Proper Draft

Owner's manual must include:
(a) Importance of proper draft;
(b) Conditions indicating inadequate draft;
(c) Conditions indicating excessive draft; and
(d) Guidance on proper stack height and proper heater locations,
i.e., not too close to neighbors or in valleys that would cause
unhealthy air quality or nuisance conditions.
2.3.10.1 No example text is supplied for (d) because state,
local and tribal requirements are model and location specific.
Exhibit 9--Example Text for Item (a):
``Draft is the force which moves air from the appliance up
through the chimney. The amount of draft in your chimney depends on
the length of the chimney, local geography, nearby obstructions and
other factors. Too much draft may cause excessive temperatures in
the appliance and may damage the catalytic combustor. Inadequate
draft may cause backpuffing into the room and `plugging' of the
chimney or the catalyst.''
Exhibit 10--Example Text for Item (b):
``Inadequate draft will cause the appliance to leak smoke into
the room through appliance and chimney connector joints.''
Exhibit 11--Example Text for Item (c):
``An uncontrollable burn or excessive temperature indicates
excessive draft.''

2.3.11 Efficiency

Owner's manual must include:
(a) Description of how the efficiency was determined, e.g., use
higher heating value of the fuel instead of lower heating value of
the fuel, discuss sweet spot versus annual average versus annual
fuel usage efficiency (AFUE);
(b) How operation and fuels affect efficiency, e.g., seasoned
wood versus high moisture fuel; operation at sweet spot versus low-
burn rates; and
(c) How location affects the efficiency, e.g., in main living
area versus basement versus outdoors in sub-freezing temperatures.

2.3.12 Smoke and Carbon Monoxide Emissions and Monitors

Owner's manual must include:
(a) Discussion of smoke and carbon monoxide (CO) emissions,
including the CO data submitted in the certification application and
expected variations for different operating conditions;
(b) Recommendation to have smoke monitors; and
