II. Background
A. Statutory Background
Section 111 of the CAA requires the EPA Administrator to list
categories of stationary sources that, in his or her judgment, cause or
contribute significantly to air pollution which may reasonably be
anticipated to endanger public health or welfare. The EPA must then
issue ``standards of performance'' for new sources in such source
categories. The EPA has the authority to define the source categories,
determine the pollutants for which standards should be developed, and
identify within each source category the facilities for which standards
of performance would be established.
Section 111(a)(1) of the CAA defines ``a standard of performance''
as ``a standard for emissions of air pollutants which reflects the
degree of emission limitation achievable through the application of the
best system of emission reduction (BSER) which (taking into account the
cost of achieving such reduction and any non-air quality health and
environmental impact and energy requirement) the Administrator
determines has been adequately demonstrated.'' This definition makes
clear that the standard of performance must be based on measures that
constitute BSER, while taking into account multiple statutory factors.
The standard that the EPA develops, based on the BSER, is commonly a
numerical emission limit, expressed as a performance level. As provided
in CAA 111(b)(5), the EPA does not prescribe a specific technology that
must be used to comply with a standard of performance. Rather, sources
generally can select any measure or combination of measures that will
achieve the emission level of the standard. Where certain statutory
criteria are met, the EPA may promulgate design, equipment, work
practice or operational standards instead of a numerical standard of
performance. See CAA 111(h)(1) and (2).
The Residential Wood Heaters source category is different from most
NSPS source categories in that it applies to mass-produced residential
consumer products. Thus, an important consideration in determining the
emission limit that is achievable through the application of the BSER
here is the cost to both manufacturers and consumers as well as any
potential environmental impact of delaying production while wood
heating devices 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 promulgation of the NSPS. Given this statutory
requirement, as discussed more fully in the Federal Register notice for
the 2015 NSPS rulemaking (80 FR 13672), the EPA adopted the stepped
(phased) approach for residential wood heaters, hydronic heaters and
forced-air furnaces to provide sufficient implementation time for
manufacturers and retailers to comply with the Step 2 limits. That is,
for the 2015 NSPS rulemaking, the EPA determined that certain emission
limits phased in over time reflect the degree of emission limitation
achievable through the application of BSER.
B. Regulatory Background
Residential wood heaters were originally listed under CAA section
111(b) in February 18, 1987 (see 52 FR 5065). The NSPS for wood heaters
(40 CFR part 60, subpart AAA) was proposed on February 18, 1987 (see 52
FR 4994) and promulgated on February 26, 1988 (see 53 FR 5859) (1988
Wood Heater NSPS). The NSPS was amended in 1998 to address an issue
related to certification testing (see 63 FR 64869).
On February 3, 2014, the EPA proposed revisions to the NSPS (see 79
FR 6330) and published notice of its final rule making revisions on
March 16, 2015 (see 80 FR 13672). The final 2015 NSPS updated the 1988
Wood Heater NSPS emission limits, eliminated exemptions over a broad
suite of residential wood combustion devices, and updated test methods
and the certification process. The 2015 NSPS also added a new subpart
(40 CFR part 60, subpart QQQQ) that covers new wood burning residential
hydronic heaters and new forced-air furnaces.
For this action, the term ``wood heaters'' refers to all appliances
covered in 40 CFR part 60, subpart AAA, and the terms ``hydronic
heaters'' and ``forced-air furnaces'' refer to appliances covered in 40
CFR part 60, subpart QQQQ. Also, for this action, the term ``wood
heating devices'' refers to all units, collectively, regulated by the
2015 NSPS (40 CFR part 60, subparts AAA and QQQQ).
In promulgating the 2015 NSPS, the EPA took a ``stepped compliance
approach'' in which certain ``Step 1''
[[Page 61588]]
standards would become effective in May 2015, and more stringent ``Step
2'' standards would become effective five years later, in May 2020.
Considering that over 90 percent of wood heating device manufacturers
and retailers are small businesses, the Agency adopted this two-phased
implementation approach to try to provide manufacturers adequate lead
time to develop, test, field evaluate and certify technologies across
their product lines to meet the Step 2 emission limits.
The Step 1 standard reflected demonstrated wood heater technologies
at the time. For wood heaters, the Step 1 limit was based on the
Washington State standard that had been in effect since 1995 and had
been met by most wood heater manufacturers. For hydronic heaters, the
Step 1 emission limit was based on the 2010 Phase 2 Voluntary Hydronic
Heater Program. The Step 1 standard for forced-air furnaces was what
the EPA concluded would be immediately achievable based on a limited
dataset (see 80 FR 13693).
For the Step 1 standards, the EPA provided a ``sell-through''
period of seven and a half months, until December 2015, to allow
retailers additional time after the effective date of the rule to sell
the non-compliant wood heaters and hydronic heaters remaining in
inventory (see 80 FR 13685). Specifically, the 2015 NSPS allowed non-
compliant wood heaters and hydronic heaters manufactured before May 15,
2015, to be imported and/or sold at retail through December 31, 2015
(see 40 CFR 60.532(a) and 60.5474(a)(1)).\2\ For the Step 2 standards,
the EPA did not provide a sell-through period following the May 2020
compliance date. The EPA concluded at the time that the 5-year period
leading up to the May 2020 Step 2 compliance date would provide
manufacturers with sufficient lead time to develop, test and certify
Step 2-compliant wood heating devices (see 80 FR 13676). However, in
light of concerns raised by manufacturers, in a separate rulemaking
action, the Agency is proposing a 2-year sell-through period for
certain types of wood heating devices that are manufactured before the
May 2020 compliance date to be imported and/or sold at retail.
---------------------------------------------------------------------------
\2\ The EPA did not provide any sell-through period for forced-
air furnaces because the EPA determined that the requirements that
became effective for these heaters in May 2015 (to revise the owner
manuals, and training and marketing materials) could be accomplished
without disrupting sales and creating undue burden on manufacturers
or retailers (see 80 FR 13682 and 13685).
---------------------------------------------------------------------------
A major component of demonstrating compliance with both the Step 1
and Step 2 standards is a certification test, using an EPA-specified
test method, for a given wood heating device. Among other requirements,
the emissions from the certification test cannot exceed the emission
limit for the standard for which it is certifying (either Step 1 or
Step 2). It is worth noting that, because these certification test
methods were developed outside of the 2015 NSPS, they have their own
requirements independent of the 2015 NSPS, such as fuel requirements.
Another important point is that the EPA-specified test methods may
not reflect how a typical consumer uses the device. Some test methods
require the use of crib wood,\3\ which is air-dried dimensional lumber,
rather than typical cord wood,\4\ or firewood. Additionally, the EPA-
specified test methods direct the certification laboratory to target
specific burn rate categories for performance assessment purposes.
---------------------------------------------------------------------------
\3\ Crib wood fuel is air dried, dimensional cut Douglas fir
lumber, arranged in the firebox per the EPA Method 28R.
\4\ Cord wood fuel is traditional firewood cut to nominal
commercial sale length and air dried.
---------------------------------------------------------------------------
III. Request for Comment
The EPA has worked with a wide array of stakeholders, including but
not limited to industry, states, and non-governmental organizations, in
implementing the 2015 NSPS and received feedback from these
stakeholders on how to improve the 2015 NSPS. Based on this feedback,
the EPA is soliciting comments on the following 10 topics:
A. Test Methods--Transition to Cord Wood
As discussed at 80 FR 13678, 13684 and 13690 in the 2015 NSPS, the
EPA contemplated requiring ``real world'' cord wood test methods for
the Step 2 standards in the final rule. However, the Agency determined
that it was premature to require a cord wood based-Step 2 emission
limit (except for forced-air furnaces for which CSA B415.1-10 already
specified cord wood as the test fuel) because no cord wood test method
for wood heaters was available at that time. Rather, the EPA based the
Step 2 emission limit on crib wood test data but included a voluntary
alternative cord wood compliance option and emission limit to encourage
manufacturers to certify with cord wood as soon as possible to provide
consumers with better information for actual in-home-use performance.
Recently, the EPA approved the use of ASTM 3053-17, finalized in
November 2017, through the EPA's Broadly Applicable Test Methods
approval process. Broadly applicable test methods Alt-125 and Alt-127
(https://www.epa.gov/emc/broadly-applicable-approved-alternative-test-methods) are now available for manufacturers wishing to use this
voluntary cord wood compliance option.
As the 2015 NSPS did not include a new test method intended to
provide ``real world'' data through cord wood compliance testing, the
EPA has received many informal comments and taken part in several
discussions concerning the differences between the existing compliance
test methods and ``real world'' cord wood compliance testing. These
discussions have led the EPA to review existing wood appliance test
methods and conduct research into the data sets provided by those test
methods. In doing so, the Agency recognizes a need to better understand
what compliance test procedures are necessary in order to provide a
cord wood emissions test data set that serves both the compliance test
benchmark (pass/fail) and ``real world'' data collection to support
other regulatory needs. Our review of existing test methods has focused
on two distinct facets of the testing procedures: (1) Particulate
collection and measurement during the testing; and (2) operation and
fueling of an appliance during the testing. Each of these two pathways
is currently represented in our compliance testing paradigms by a
separate test methodology. For example, ASTM E2515-11 serves as the
particulate collection and measurement test method for all existing
NSPS compliance test requirements, but this test method is always used
in conjunction with any one of several different operation and fueling
protocols, such as the EPA Method 28R for crib wood fuel testing of a
wood heater or the EPA Method 28WHH for crib wood fuel testing of a
hydronic heater. There is inherent variability in each facet of the
testing, and the overall variability of the testing result combines the
variability inherent to each facet. The EPA recognizes that moving away
from a crib wood fuel compliance testing paradigm to a cord wood fuel
compliance paradigm involves the introduction of the additional
variability inherent to cord wood fuel including the use of various
species of cord wood fuel across different regions of the U.S. and in
different countries where compliance testing may occur. In that light,
a review of test method processes and procedures is appropriate with
respect to handling this additional and unknown variability,
[[Page 61589]]
and the Agency is seeking public comment regarding the direction and
extent to which the EPA should undertake such evaluations of existing
test methods, including the scope of test method, appropriateness of
testing procedures, validation of test methodology, and revision and/or
developing new compliance test methods not currently associated with
the existing NSPS standards. To inform comments, the Agency would point
out that the EPA has an existing guideline covering Validation and Peer
Review of test methods: (https://www.epa.gov/sites/production/files/2016-02/documents/chemical_method_guide_revised_020316.pdf). While the
EPA Methods 5H and 5G (both particulate test methods) underwent a
similar review prior to their publication in the 1988 NSPS (see: R. Gay
and J. Shah, Technical Support Document For Residential Wood
Combustion, EPA-450/4-85-012, U.S. Environmental Protection Agency,
Research Triangle Park, NC, February 1986), those are the only wood
burning appliance test methods upon which the EPA has collected such
data and done such analysis. The EPA Method 5G is closely related to
the current ASTM E2515-11, which is required for measuring particulate
throughout the 40 CFR part 60, subparts AAA and QQQQ, and so some
understanding of this method variability of ASTM E2515-11 exists
through our understanding of the EPA Method 5G. Beyond particulate
measurement, the EPA's Method 28, Method 28R, Method 28WHH, Method
28WHH-PTS and all other operation and fueling protocols required by 40
CFR part 60, subparts AAA and QQQQ have not been individually validated
or assessed through such a process.
In addition to the lack of information surrounding the validation
of these operating and fueling protocols, the Agency recognizes the
need to understand the variability introduced to a compliance test
protocol through the combustion of various fuel species. Beyond this,
the Agency seeks comment on the need to develop a thorough
understanding of appliance use and emissions from typical appliance
operations such as startup, refueling (adding logs) and other common
modes of operation more representative of actual in-home use than the
``high burn, mid burn, and low burn'' modes currently required by
Method 28R and/or similar operating conditions required by the various
operating and fueling protocols throughout 40 CFR part 60, subparts AAA
and QQQQ. The Agency realizes that ``real-world'' data collection stems
from an understanding of the actual in-home use of the appliance, and
any compliance test paradigm relies on consistent application of
appliance fueling and operation during performance tests and, while our
existing compliance paradigms provide some testing consistency, the
Agency would like information supporting their use or specific
information as to more appropriate compliance operation and fueling
protocol direction for this program.
The EPA seeks comment on whether existing operation and fueling
protocols are suited to deliver an appropriate compliance test result
and if existing operation and fueling protocols are suited to deliver
``real world'' emissions data where such data are a necessary output of
this program. The EPA also seeks comment on the need to validate
existing operation and fueling protocols and/or expend time and
resources to develop new validated operation and fueling protocol
methods in support of cord wood fuel compliance testing and providing
such ``real world'' emissions data from those tests. Relatedly, the EPA
also seeks comment with respect to developing new emission standards to
correspond with new test methods, if new test method development is
found to be necessary. Commenters should provide relevant information
and data to support their comments.
B. Feasibility of the Step 2 Compliance Date of May 15, 2020
While some manufacturers have begun manufacturing Step 2-compliant
units, the EPA has learned of issues with compliance with these
emission limits by the May 15, 2020, deadline. In the 2015 NSPS, the
EPA concluded that the 5-year period leading up to the May 2020 Step 2
compliance date would provide manufacturers with sufficient lead time
to develop, test and certify Step 2-compliant wood heating devices (see
80 FR 13676).\5\
---------------------------------------------------------------------------
\5\ The EPA provided further explanation in the 2015 Response to
Comments (RTC) document (Docket ID EPA-HQ-OAR-2009-0734-1775). On
page 99 of the RTC, the EPA noted that the 5-year period from 2015
to 2020 ``matches the window of time many manufacturers noted they
would require to conduct research and development (R&D) and bring a
new model to market,'' and on page 231 of the RTC, the EPA concluded
that the Step 2 standards provide ``appropriate lead times for
manufacturers to redesign their model lines to accommodate the
improved technology across multiple model lines and test, field
evaluate, and certify new model lines.''
---------------------------------------------------------------------------
The Step 1 emission standards reflected demonstrated wood heater
technologies at that time. Step 2 standards were deemed to be
reasonable levels of emission control five years after promulgation. As
a part of the 2015 rulemaking, the EPA identified the percentage of
wood heaters estimated to be meeting the Step 2 standards prior to
promulgation of the 2015 NSPS as 70 percent of pellet stoves and 26
percent of wood stoves. Similarly, 18 percent of hydronic heaters were
meeting the Step 2 standards prior to promulgation of the 2015 NSPS,
while the limited dataset for forced-air furnaces showed no models
meeting the Step 2 standards prior to promulgation of the 2015 NSPS. As
of March 20, 2018, there were a total of 78 (44 pellet and 34 crib/cord
wood) models that when certified for the Step 1 and Step 2 standards
reported emission levels that met the Step 2 standard for wood heaters
(as required under 40 CFR 60.532(b) or 60.532(c)). In addition, there
are nine models that met the Step 2 standard for hydronic heaters (as
required under 40 CFR 60.5474(a)(2) or (b)(3)) and one model that met
the Step 2 standard for forced-air furnaces (as required under 40 CFR
60.5474(a)(6)) based on the Step 2 certification process. The inventory
of certified models as of March 2018 is provided in the document
titled: ``List of EPA certified Wood Heating Devices March 2018,''
which is available in the docket and at the website https://www.epa.gov/compliance/wood-heater-compliance-monitoring-program. The
EPA requests comment and information regarding the percentage of models
referenced above that the agency projects are meeting standards for
each type of equipment.
Recently, some manufacturers have indicated that they need more
time to develop, test, and certify wood heating devices that meet the
Step 2 standard and that the costs of Step 2 compliance are beyond what
the industry can bear. As a result of this input, the EPA is soliciting
comment on whether it is feasible/practicable for manufacturers to meet
the Step 2 emission limits by May 15, 2020. Commenters should discuss
whether the Step 2 compliance date is achievable or not and should
provide relevant information and data to support their position. For
example, commenters may wish to address the following questions:
1. Are there other factors that have changed or that the Agency did
not consider when issuing the 2015 NSPS that have influenced whether
some manufacturers are able to comply, and others are not? Why are some
manufacturers able to comply with the Step 2 emission limits by May
2020 and others cannot comply by then?
2. For manufacturers expecting to achieve Step 2 emission limits by
May 2020, what is the time and cost to bring
[[Page 61590]]
the model to market and how does this compare to the EPA's 2015 NSPS
estimates? Were there other timing considerations associated with new
state level requirements that were issued in the intervening time
between 2015 NSPS promulgation and the May 2020 deadline that may have
changed the design timeline? Do manufacturers, considering the size of
their businesses, typically sell different models to meet differing
state standards or do manufacturers typically have just one model for
the nation? Does the manufacturer's business model and distribution
chain affect their ability to comply by the compliance deadline? If so,
please provide specific information on how this occurs. What is the
typical engineering design cycle for small businesses and did five
years provide enough time?
3. For manufacturers that do not expect to achieve the Step 2
emission limits by May 2020, what factors are preventing your model(s)
from meeting the emission limits? Are there other factors that have
changed or that the Agency did not consider when issuing the 2015 NSPS
that have had an effect on meeting the May 2020 emission limits? Are
there features of wood heating devices that make meeting Step 2
standards more challenging or more expensive? Does a lack of desirable
consumer features lead to delays in replacing older dirty stoves or
promote switching to other fuels?
The EPA is also soliciting comment on how much the compliance date
should be extended, if at all. Commenters should provide relevant
information and data to support any request for an extension of the
compliance date. For example, commenters may wish to address the
following questions:
1. What new factors resulted in the need for time beyond the five
years of the 2015 NSPS? The Agency seeks comment and information
explaining how cost affects meeting the Step 2 emission limits by May
2020, including why cost projections have changed since the 2015 NSPS,
along with relevant data on the cost of research and development,
certification testing, and bringing a model to market. Are there other
cost considerations such as material costs, warranty costs,
installation costs, or maintenance costs that were unexpected or
different from what the Agency estimated in the 2015 NSPS? Have there
been any other unforeseen impacts on costs for manufacturers due to
changes in consumer preferences or attitudes towards the devices and
products that would be needed to comply with Step 2? For example, would
any of the new designs needed to meet the May 2020 standards impact the
size of the unit, how much it would cost consumers to operate it, or
change the maintenance frequency or cost?
2. If more time is needed to meet the Step 2 emission limits, the
EPA seeks comment on the time and resources devoted to research and
development of a Step 2 model since 2014. Commenters should include
information regarding time spent on emissions testing, and the number
of runs/tests passed versus the number failed. Both manufacturer-
produced test data and certified laboratory test data are of interest
to the EPA. The Agency is also interested in receiving information
regarding emission reduction efforts and any other information
outlining attempts to develop a Step 2-compliant model.
3. If more time is needed to meet the Step 2 emission limits, then
how much additional time is needed? For example, the Agency solicits
comments and detailed information regarding the timetable for
conducting research and development, additional testing, developing
saleable products, marketing, and any other relevant information and
data that supports a request for a delayed compliance date.
The EPA also solicits comment on the environmental consequences and
public health effects, if any, of delaying compliance.
C. Step 2 Emission Limit for Forced-Air Furnaces
At the time of the 2015 NSPS, the EPA expected most forced-air
furnace manufacturers to transfer technology and knowledge from wood
heaters and hydronic heaters to design Step 2-compliant forced-air
furnaces by the 2020 compliance date; however, the EPA is only aware of
one manufacturer that has received EPA certification as being Step 2
compliant, see website: https://www.epa.gov/compliance/wood-heater-compliance-monitoring-program. Prior to the 2015 NSPS, some small
forced-air furnace manufacturers had already transferred technology
from wood heaters to forced-air furnaces to achieve good performance as
discussed at 80 FR 13687. Several manufacturers, however, question
whether it is feasible to transfer technology from hydronic heaters.
These manufacturers point to the fact that space limitations may affect
their ability to adequately insulate models that may be installed in
close proximity to combustibles. The Agency requests comment on the
installation of cord wood-fired indoor hydronic heaters without large
volumes of thermal insulation around the firebox, and whether this
approach is feasible and cost effective for forced-air furnaces. The
EPA also seeks comment on whether technology transfer is necessary for
forced-air furnaces to meet the Step 2 emission limit, and on the
technological feasibility and costs of alternatives to thermal
insulation around the firebox. The EPA solicits comment on the
feasibility of the Step 2 limit for forced-air furnaces and what
factors the Agency should consider concerning the feasibility and costs
of transferring technologies from other wood heater devices to forced-
air furnaces. Comments should include information and data supporting
their perspective.
Also, since promulgating the 2015 NSPS, the EPA has received
feedback from some manufacturers that complying with the Step 2
emission limit is cost prohibitive. Therefore, the EPA is soliciting
comment on whether, regardless of technical feasibility concerns, it is
economically feasible to comply with the Step 2 emission limit for
forced-air furnaces. Commenters should explain the issues regarding
costs and the feasibility/practicability for achieving the Step 2
emission limit and whether changing the Step 2 emission limit would
alleviate these issues, along with data supporting the position. The
EPA is also soliciting comment on the environmental and public health
effects, if any, of modifying the Step 2 emission limit for forced-air
furnaces.
As noted earlier, the EPA is also soliciting comment on the
feasibility of the Step 2 compliance date of May 15, 2020. The EPA is
soliciting comment on whether to extend the Step 2 compliance date for
forced-air furnaces. Commenters should provide relevant information and
data to support any request for a delayed compliance date. The EPA is
also soliciting comment on the environmental and public health effects,
if any, of potential extensions of the Step 2 compliance date for
forced-air furnaces.
D. Step 2 Emission Limit for Hydronic Heaters
For the 2015 NSPS, the EPA set the Step 2 emission limits based on
its determination of the BSER, which takes into account the cost of
achieving such reduction and any non-air quality health and
environmental impact and energy requirements (See 80 FR 13687). Since
promulgation, however, the EPA has received comments from industry
representatives that the cost of compliance with Step 2 emission limits
for hydronic heaters is exceeding the EPA's original estimation. The
EPA
[[Page 61591]]
estimated a yearly cost of $46 million (2013$), that would be incurred
from 2015 to 2020, for implementation of the 2015 NSPS. Details of how
costs of the 2015 NSPS were estimated can be found in Chapter 5 of the
Regulatory Impact Analysis for that standard.\6\ Furthermore, these
comments have indicated that the excess costs have made complying with
the Step 2 emission limit cost prohibitive. Are there other cost
considerations such as material costs, warranty costs, installation
costs, maintenance costs, or other costs that were unexpected or
different from what the Agency estimated in the 2015 NSPS? Have there
been any other unforeseen impacts on costs for manufacturers due to
changes in consumer preferences or attitudes towards the devices and
products that would be needed to comply with Step 2? Therefore, the EPA
is soliciting comment on the feasibility of complying with the Step 2
emission limit for hydronic heaters. Commenters should explain the
issues regarding the practicability of achieving the Step 2 emission
limits, whether the EPA's estimated costs are being exceeded \7\ or if
there are other aspects of the costs that the Agency had not previously
considered, and whether changing the Step 2 emission limit will
alleviate these issues. Commenters should provide relevant information
and data to support their positions. The EPA is also soliciting comment
regarding the potential environmental and public health effects, if
any, of modifying the Step 2 emission limits for hydronic heaters.

Residential Wood Heater Manufacturer Cost Impacts. January 30, 2015.
Available in Docket ID No. EPA-HQ-OAR-2009-0734.
---------------------------------------------------------------------------
As of March 20, 2018, there are nine models that meet the Step 2
standard for hydronic heaters (as required under 40 CFR 60.5474(a)(2)
and 60.5474(b)(2) or (b)(3)), and one model that meets the Step 2
standard for forced-air furnaces (as required under 40 CFR
60.5474(a)(6) and 60.5474(b)(6)) based on the Step 2 certification
process. These models are listed in the document titled ``List of EPA
certified Wood Heating Devices March 2018,'' which is in the docket at
EPA-HQ-OAR-2018-0196. Also see link https://www.epa.gov/compliance/wood-heater-compliance-monitoring-program.
The EPA is requesting comment regarding these models and models
that have not met the Step 2 standard for hydronic heaters and what
they demonstrate about achieving the standard at a reasonable cost.
Specifically, for manufacturers expecting to be unable to design a
hydronic heater to meet the Step 2 standard, the EPA is interested in
whether the Step 2 standard applicable to your device is achievable at
a reasonable cost by the May 2020 Step 2 compliance date. The Agency is
also interested in receiving information regarding efforts undertaken
to design hydronic heaters to meet the applicable Step 2 standard,
including cost, and if one or more models are expected to be ready for
certification by the May 2020 Step 2 compliance date, when you expect
to submit your application(s) for certification to the EPA.
As noted earlier, the EPA is also soliciting comment on the
feasibility of the Step 2 compliance date of May 15, 2020. The EPA is
soliciting comment on whether to extend the Step 2 compliance date for
hydronic heaters. Commenters should provide relevant information and
data to support any request for a delayed compliance date. The EPA is
also soliciting comment on the environmental and public health effects,
if any, of potential extensions of the Step 2 compliance date for
hydronic heaters.
E. Step 2 Emission Limit Based on Weighted Averages Versus Individual
Burn Rates for Hydronic Heaters and Forced-Air Furnaces
For hydronic heaters, the 2015 NSPS retained the proposed Step 1
emission cap of 18 grams per hour (g/hr) for all burn rates. For
forced-air furnaces, the 2015 NSPS does not require an emission cap for
any burn rates for Step 1. The Step 2 requirements for hydronic heaters
did not retain the g/hr cap. Instead, to balance industry's concern
with the g/hr cap with concerns about very large emissions at
individual burn rates, the Step 2 emission standards for hydronic
heaters and forced-air furnaces require the devices to meet the
emission limits for crib wood and cord wood, at each individual burn
rate (see 80 CFR 13684 and 13690).
The emission limits for hydronic heaters reflect the data available
for the 2015 NSPS rulemaking, when 18 percent of hydronic heaters in
the EPA's Voluntary Hydronic Heater Program already met the Step 2
standard. For forced-air furnaces, the EPA determined that research and
development would be needed in order to meet the Step 2 limits.\8\
---------------------------------------------------------------------------
\8\ Memo to Gil Wood, USEPA, from EC/R Inc. Estimated
Residential Wood Heater Manufacturer Cost Impacts. January 30, 2015.
Available in Docket ID No. EPA-HQ-OAR-2009-0734.
---------------------------------------------------------------------------
In the 2014 NSPS proposal, the EPA proposed a weighted average
approach for compliance. But, because of the large emissions that could
potentially result from individual burn rates, along with the proposed
weighted average approach, the EPA also proposed a g/hr cap for the
certification test. Comments received from industry representatives in
2014 suggested that the g/hr emission cap would be too difficult to
meet. To accommodate these concerns, and after considering other public
comments, the EPA finalized the emission standards without a g/hr cap
but required the devices to meet the emission limit at each individual
burn rate to prevent large emission discharges.
Based on concerns raised since promulgating the 2015 NSPS, the EPA
is soliciting comment on determining compliance with weighted averages
instead of individual burn rates. Commenters should describe the
relevant issues pertaining to compliance with the Step 2 emission limit
with individual burn rates versus a weighted average and also include
data to support their position. Commenters should also discuss and
support with data how a weighted average would impact emissions and
compliance costs.
F. Step 2 Emission Limit for Wood Heaters
As of March 20, 2018, there were a total of 78 models that when
certified for the Step 1 and Step 2 standards reported emission levels
that meet the Step 2 standard for wood heaters (as required under 40
CFR 60.532(b) or 60.532(c)). These models are listed in the document
titled ``List of EPA certified Wood Heating Devices March 2018,'' which
is in the docket at EPA-HQ-OAR-2018-0196. Also see link https://www.epa.gov/compliance/wood-heater-compliance-monitoring-program.
The EPA is requesting comment on all aspects of the costs
associated with the Step 2 standards for wood heaters compared to the
costs estimated by the EPA in the 2015 NSPS and whether Step 2 is
achievable at a reasonable cost. The EPA requests comment on the
potential cost difference for consumers to operate different types of
wood heaters and, in particular, the cost of operating a pellet wood
heater compared to the cost of operating a cord/crib wood heater.
If you are a manufacturer that has been unable to design a wood
heater to
[[Page 61592]]
meet the Step 2 standard, the EPA is interested in whether you think
the Step 2 standard applicable to your device is achievable at a mean
capital cost per model of $162,300 (for wood stoves and pellet stoves,
in 2016 dollars) by the May 2020 Step 2 compliance date and whether
this cost is reasonable.\9\ The EPA is requesting comment on the
technical feasibility of achieving the Step 2 standards for 40 CFR part
60, subpart AAA wood heaters including both pellet and cord/crib wood
heaters and whether the Agency should consider creating separate source
categories for these different wood heaters types.\10\ Since more
pellet stoves meet Step 2 than crib/cord wood stoves, the EPA is
interested in hearing from manufacturers and the public on the concept
of different emission standards for pellet-fired and crib/cord wood-
fired heating devices. The Agency is also interested in receiving
information regarding the efforts you have undertaken to design a wood
heater, both for pellet and crib/cord wood heaters, to meet the
applicable Step 2 standard, including the cost of your efforts to do
so. In addition, the EPA requests information on how many models of
pellet and crib/cord wood heaters you expect will be and will not be
ready for certification by the May 2020 Step 2 compliance date, and
when you expect to submit your application(s) for certification to the
EPA.
---------------------------------------------------------------------------
\9\ Estimate is based on the mean capital cost per model in
Table 5-1, p. 5-5 of that RIA, escalated to 2016 dollars from the
original 2013 dollar estimate of $156,000. Escalation uses the
annual value of GDP implicit price deflator, which is 1.04127 higher
in 2016 than 2013.
\10\ In the 2015 final rule, the EPA noted that it was ``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.'' Furthermore, as noted in the Response to
Comment document: ``It is up to manufacturers to decide what
combustion technology/wood fuel to use to meet the emission limits
and up to consumers to decide what types of heaters they wish to
purchase that are certified to meet those limits.'' Performance
standards may drive competition in the marketplace; however,
maintaining just one source category for these wood heaters may
distort the marketplace and raise costs for both manufacturers and
consumers if only a limited number of wood heaters or predominantly
one type of wood heater can meet the Step 2 standards. Pellet wood
heaters may be more readily able to meet more stringent standards
due to the consistent fuel type and continual operating mode
compared to crib/cord wood heaters that may require more costly
redesigns to meet the Step 2 standards. In addition, the agency did
not consider the lifetime operating costs in the 2015 NSPS as the
difference in fuel costs between operating a crib/cord wood and
pellet wood heater could be considerable over the lifetime of the
wood heater if consumer choice is limited to just pellet stoves due
to the Step 2 standards.
---------------------------------------------------------------------------
Additionally, the EPA has received informal comments from several
parties regarding emissions testing variability and, along with those
discussions, issues have been raised regarding the units or format of
the Step 2 emission limit in 40 CFR 60, subpart AAA. One issue raised
is that the existing emission limit in units of grams per hour (g/hr)
increases variability in that the duration of the performance test
directly impacts the g/hr result, thus incentivizing longer test
periods. The EPA is soliciting comments on this form of the standard
(g/hr) and whether it is appropriate for the purpose of defining the
compliance limit and, if not, what form of a standard would be more
appropriate and reasons supporting those positions. Other possible unit
options for the emission limit could be g/kg or lb/mmBtu. Commenters
are asked to provide relevant information and data (where available) to
support their comments.
G. The EPA Compliance Audit Testing
The EPA seeks comment with respect to the EPA compliance audit test
provisions in the current rules (2015 NSPS), found at 40 CFR 60.533(n)
(80 FR 13708) for wood heaters and at 40 CFR 60.5475(n) (80 FR 13721)
for hydronic heaters and forced-air furnaces. Specifically, the Agency
is seeking comment on whether revisions to the current compliance audit
test provisions are necessary to ensure compliance. First, the Agency
is seeking comment on 40 CFR 60.533 (n)(2)(i) and 40 CFR
60.5475(n)(2)(i) regarding if it is appropriate for the EPA to select a
lab to perform the audit test from any approved test laboratory, and
whether the EPA should also consider using a federal laboratory.
Alternatively, the EPA seeks comment on whether audit tests should be
performed by the same lab that did the certification test for a given
wood heater appliance. If the audit test should be done by the
certifying lab, the EPA seeks comment on how to handle situations where
the original certifying lab is out of business or unable to accommodate
the audit test. Commenters should include any relevant information and
data that support their views and comments.
Second, as some variability is inherent in emissions testing, the
Agency is seeking comment (and information) on whether and, if so, to
what degree, the EPA should consider this variability when assessing
the result of an audit test to determine if a wood burning appliance
successfully passed the test, or not. Please provide relevant
information and data to support your comments.
Third, the Agency is seeking comment on establishing (as well as
how best to manage the regulatory cost of), through NSPS regulation, a
program using ASTM E691-99 ``Standard Practice for Conducting an
Interlaboratory Study to Determine the Precision of a Test Method.''
The intent of such a program would be to develop and establish wood
heating device audit test acceptability criteria, and to provide data
useful to the EPA in both refining wood heating device test methodology
development and in aiding the regulatory data collection with respect
to wood heater, forced-air furnace, and hydronic heater emissions and
standards setting processes. The EPA is also requesting comment on the
cost or any concerns with specifying a specific certification lab and
any discussion of the use of a federal versus a private lab. For the
2015 NSPS, the EPA estimated a cost of $63,564 for each compliance
audit conducted for each hydronic heater and forced-air furnace over
the period of 2015 to 2017, an estimate documented in the Supporting
Statement for the standard.\11\

Residential Hydronic Heaters and Forced-Air Furnaces (40 CFR part
60, subpart QQQQ) (Final Rule). January 2015. Pp. 11-12.
---------------------------------------------------------------------------
H. ISO-Accredited Third-Party Review
In the 2015 NSPS, the EPA included a new feature to improve the
process by which manufacturers of wood heating devices apply for
certification (see 80 FR 13684, and the ISO-accredited third-party
review at 80 FR 13706 and 80 FR 13719). The ISO-accredited third-party
review was included in the 2015 NSPS to streamline and speed up the
review process.
The EPA is seeking comment on whether third-party review has
streamlined the process for manufacturers to submit their certification
applications and/or what issues and problems stakeholders have
experienced with third-party review process. The EPA also solicits
suggestions for improving the third-party review and reducing
regulatory burden, including what specific rule changes would be
appropriate, and why. Commenters should provide relevant information
and data to support their comments and suggestions.
The current process allows the EPA-approved certifying lab to also
act as the third-party reviewer for a given appliance. Some external
stakeholders have raised concerns about allowing a lab to act as both
the certifying test lab and third-party reviewer for a given
certification test. The EPA solicits comments as to whether an EPA-
approved lab should be allowed to act
[[Page 61593]]
as both the certifying lab and third-party reviewer. Commenters should
address whether this is a problem and provide available data to support
their position.
I. Electronic Reporting Tool (ERT)
The EPA seeks comment on establishing electronic reporting for
submitting the non-confidential business information (CBI)
certification application, including the compliance test data, rather
than via hard copy, to relieve manufacturer burden and enhance
efficiencies. One possibility is the EPA's Electronic Reporting Tool
(ERT). The ERT is a Microsoft Access[supreg] application that generates
electronic versions of source test reports. Information on the ERT can
be found at https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert. The EPA believes that using the ERT will
relieve the burden on manufacturers in the certification application
process by standardizing the reporting format by having specific data
elements reported, thereby helping to ensure completeness and accuracy
of the data submitted. As a result, the electronically submitted
application with complete and accurate data will enable an efficient
and timely review. In addition, because the ERT performs the required
method calculations, certification test report errors will be reduced
and the burden of performing these calculations manually will be
eliminated for the manufacturers as well as for the third-party
certifiers and the EPA reviewers. If the ERT were used, it would
generate a non-CBI test report (in pdf format) along with the ERT-
generated Access database (accdb) file that could be submitted to the
EPA for certification and once certified, posted to the manufacturer's
website. This ERT-generated test report would include a list of
attachments in the ERT file but not the attachments themselves. The
attachments would be contained in the ERT accdb file and if posted to
the manufacturer's website would be available to the public. Posting
the pdf will also address the version control concerns of the ERT-
generated database file. These two components could satisfy the
reporting requirements in 80 FR 13713 and 13725. The EPA seeks comment
on whether to include the option of using the ERT to create a non-CBI
and a CBI test report and certification package (pdf and .accdb file)
that satisfies the reporting requirements in 40 CFR 60.537(f) and
60.5479(f), which requires the manufacturer to submit the results of a
certification test within 60 days of completing each performance test.
If the EPA changes the current provisions, the Agency expects that the
manufacturers would still be required to post the full non-CBI test
report (pdf with all attachments or ERT generated pdf with the Access
database (accdb) file) on the manufacturer's website and submit the CBI
test report separately to the EPA. Manufacturers, who claim that some
of the information being submitted is CBI (e.g., design drawings),
could also utilize the same non-CBI test report generated by the ERT
and add the design drawings as an attachment to be submitted to the EPA
as CBI in order to satisfy the requirements under 40 CFR 60.537(f) and
60.5479(f). Similarly, the non-CBI report with no CBI information
attached could be posted to the manufacturer's website within 30 days
of receiving a certification of compliance to satisfy 40 CFR 60.537(g)
and 60.5479(g). Please provide as much detailed information as possible
to support your comments regarding this approach.
J. Warranty Requirements for Certified Appliances
The 2015 NSPS requires owners or operators to operate wood heating
devices consistent with the owner's manual (see 40 CFR 60.532(f)(13)
and (g) and 60.5474(f)(13) and (g)). The 2015 NSPS also requires
manufacturers to provide an owner's manual that clearly states that
operation in a manner inconsistent with the manual, such as burning
prohibited material or pellets that do not meet the minimum
requirements of the 2015 Rule, would void the warranty (see 80 FR
13751, appendix I to Part 60). The cost of this requirement to provide
an owner's manual is an average of $3,750 per hydronic heater or
forced-air furnace model over the time period of 2015 to 2017,
according to the Supporting Statement for the 2015 NSPS.\12\ Although
numerous states expressed their support for these requirements as a
mechanism to help enforce the 2015 NSPS, some stakeholders have
questioned whether the EPA has the statutory authority to impose these
requirements. Stakeholders have also raised other issues regarding the
warranty requirements. The EPA is, therefore, soliciting comments
regarding retention, revision, or elimination of the warranty
requirements. For example, the EPA would be interested in hearing
whether such requirements are necessary for the safe and efficient
operation of the wood heater devices. Commenters supporting retention
of the requirements should address whether any changes are recommended
to the warranty requirements along with data, as appropriate, and an
explanation to support their position. Commenters supporting
elimination of the requirements should provide an explanation to
support their position.

VII. Statutory and Executive Order Reviews
Under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993), this is a ``significant
regulatory action.'' Accordingly, the EPA submitted this action to the
Office of Management and Budget (OMB) for review under Executive Order
12866 and any changes made in response to OMB recommendations have been
documented in the docket for this action. Because this action does not
propose or impose any requirements, and instead seeks comments and
suggestions for the Agency to consider in possibly developing a
subsequent proposed rule, the various statutes and Executive Orders
that normally apply to rulemaking do not apply in this case. Should the
EPA subsequently determine to pursue a rulemaking, the EPA will address
the statutes and Executive Orders as applicable to that rulemaking.
