On February 3, 2014, at 79 FR 6330,
the EPA proposed to amend standards
of performance for New Residential
Wood Heaters and to add two new
subparts: Standards of Performance for
New Residential Hydronic Heaters and
Forced-Air Furnaces and Standards of
Performance for New Residential
Masonry Heaters. The EPA is issuing
this NODA in support of the proposed
standards. Through this NODA, the EPA
is making available to the public, and
soliciting comment on, additional
information on residential wood heater
testing and certification that has been
added to the docket for the proposed
rule. Specifically, we are making
available the following: (1) Additional
details of certification testing (using crib
wood) of wood stoves and pellet stoves
certified by the EPA between January 1,
2010, and May 30, 2014; (2) details of
cord wood testing by two manufacturers
of their EPA-certified catalytic wood
stoves; and (3) details of cord wood
testing by Brookhaven National
Laboratory (BNL), under contract to the
EPA, of an EPA-certified noncatalytic
wood stove.
1. Additional Details of Certification
Testing (using crib wood) of Wood
Stoves and Pellet Stoves Certified by
EPA between January 1, 2010 and May
30, 2014. All EPA-certified wood
heaters that are offered or advertised for
sale in the United States are subject to
the current (1988) New Source
Performance Standard (NSPS) for New
Residential Wood Heaters under the
Clean Air Act (40 CFR part 60, subpart
AAA). These EPA-certified appliances
are required to meet the particulate
emissions limit of 7.5 grams per hour
VerDate Mar<15>2010
16:47 Jun 30, 2014
Jkt 232001
(g/hr) for non-catalytic wood heaters
and 4.1 g/hr for catalytic wood heaters.1
The model line certifications are based
primarily on testing of representative
stoves by EPA-accredited test
laboratories according to EPA Method
28. Method 28 and the NSPS require
testing for each of four burn rate
categories. Category 4 is the maximum
burn rate. Category 1 is the minimum
burn rate. Categories 2 and 3 are in
between. In the EPA’s February 3, 2014,
proposal, we proposed to update and
strengthen the existing emission limits
for these wood heaters over a 5-year
period. One of the aspects of the
proposal included requiring compliance
for each of the individual burn rates
rather than just the weighted average.
These additional data supplement the
previous data in the docket, which are
for wood stoves certified prior to
January 1, 2010.
As of May 30, 2014, the EPA has
certified approximately 1,000 wood and
pellet stove model lines that comply
with the current NSPS. Summary
information, including weighted
emission averages, for these stoves is
located at: https://www.epa.gov/
Compliance/resources/publications/
monitoring/caa/woodstoves/
certifiedwood.pdf.
From February 1988 to December 31,
2009, the EPA certified over 900 wood
stove model lines. Particulate matter
emissions by burn rate for most of the
stoves in production on December 31,
2009, were summarized by the Hearth,
Patio and Barbecue Association (HPBA)
in a database for the EPA and the EPA
1 Under state law, wood stoves offered for sale in
the state of Washington must meet a particulate
emissions limit of 4.5 g/hr for non-catalytic wood
stoves and 2.5 g/hr for catalytic wood stoves.
PO 00000

included it in the docket prior to the
February 3, 2014, proposal.
Since December 31, 2009, the EPA has
certified over 100 wood stove model
lines that comply with the current
NSPS. The EPA is announcing the
availability of detailed emissions data
for each of these model lines certified
since December 31, 2009. Manufacturers
and laboratories previously used allencompassing CBI claims to restrict
public access to these emission data.
The EPA has gone through the official
CBI process to release the emission data.
The following data, for each model
line certified since December 31, 2009,
are available in the docket for the
proposed rule (https://www
.regulations.gov/#!docketDetail;D=EPAHQ-OAR-2009-0734):
• Year of certification;
• Average weighted emission rate;
• Device type (i.e., catalytic stove,
non-catalytic stove, or pellet stove);
• EPA test method used (e.g., 5G or
5H); and
• Emission results for individual burn
categories for all burn rates—Categories
1, 2, 3 and 4. In some cases, there are
multiple test runs for some burn rate
categories.
The EPA asks for comments on these
data and how they may influence the
final rule.
2. Details of Cord Wood Testing by
Two Manufacturers of Their EPAcertified Catalytic Wood Stoves. The
EPA has received emissions test data
from two catalytic wood stove
manufacturers that show their EPAcertified wood stoves tested using cord
wood—and making no design changes
to adjust for crib wood versus cord
wood in the tests—have similar
emissions as stoves tested using crib
wood. That is, the test data for an EPA-

01JYP1
tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 126 / Tuesday, July 1, 2014 / Proposed Rules
certified Woodstock Soapstone stove
and two EPA-certified stoves produced
by another manufacturer show
particulate emission rates (g/hr) using
cord wood that are equal to or less than
the corresponding test data using crib
wood for all burn rates. The EPA asks
for comments on these data and how
they may influence the final rule.
3. Details of Cord Wood Testing by
Brookhaven National Laboratory (BNL),
under Contract to the EPA, of an EPAcertified Noncatalytic Wood Stove.
Numerous comments on the February 3,
2014, proposal suggest that
manufacturers tune their stoves to the
EPA crib wood certification test method
and that they would need to re-tune
their stoves for the proposed Step 2 cord
wood certification test method. We
believe this is true and that
manufacturers will soon 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 for crib wood versus cord wood.
However, numerous non-catalytic stove
manufacturers have indicated that they
are waiting for the proposed NSPS
revisions to become final before they
undergo the expense of such testing. At
this time, no manufacturer has
submitted particulate matter emissions
test data for non-catalytic wood stoves
tuned to burn cord wood during tests
similar to the EPA certification tests or
the ASTM (formerly known as the
American Society for Testing and
Materials) draft cord wood test method.
In June 2014, BNL (under an EPA
contract) conducted new emissions
testing of a popular non-catalytic EPAcertified wood stove using cord wood.
Existing EPA certification test data for
crib wood based on the current EPA
Test Method 5G (https://www.epa.gov/
ttnemc01/promgate/m-05g.pdf) were
compared to the new test data for using
cord wood (with no stove design
changes). Use of existing crib wood data
were used for the comparison in order
to minimize the cost of the additional
testing. We note that this raises the
question whether new crib wood testing
would have produced similar results as
the previous crib wood testing. Also, we
note that the new cord wood testing was
conducted with Method 5H, whereas
the previous certification testing was
conducted with Method 5G. The results
of the test show:
a. For a popular, current model noncatalytic stove that was not adjusted by
the manufacturer for burning cord wood
instead of crib wood during the
certification test, the emission test
results can be significantly higher than
the crib emission test results. As
VerDate Mar<15>2010
16:47 Jun 30, 2014
Jkt 232001
discussed above, the proposed Step 2
reasonably anticipates that the
manufacturers would 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 for cribs versus cord wood.
However, that was not done for this new
test series.
b. Repeatability of cord wood test
method results can sometimes be very
good. For example, the results for three
replicate tests for burn rate Category 4
(the maximum burn rate) were within
15 percent of each other.
c. Higher moisture content of the fuel
can increase particulate matter
emissions.
The complete BNL test report and
summary have been added to the docket
for the proposed rule at: https://www
.regulations.gov/#!docketDetail;D=EPAHQ-OAR-2009-0734. The EPA asks for
comments on these data and how they
may influence the final rule.

In the
‘‘Rules and Regulations’’ section of this
Federal Register (FR), the EPA is
codifying and incorporating by
reference the State’s hazardous waste
program as direct final rule. The EPA
did not make a proposal prior to the
direct final rule because we believe
these actions are not controversial and
do not expect comments that oppose
them. We have explained the reasons for
this codification and incorporation by
reference in the preamble to the direct
final rule. Therefore, the purpose of this
FR document is to codify Oklahoma’s
base hazardous waste management
program and its program revisions
through RCRA Cluster XXI (see 78 FR
32161) May 29, 2013. The EPA provided
notices and opportunity for comments
on the Agency’s decisions to authorize
the Oklahoma program, and the EPA is
not now reopening the decisions, nor
requesting comments, on the Oklahoma
authorizations as published in the FR
notices specified in Section B of the
direct final rule FR document.
This document incorporates by
reference Oklahoma’s hazardous waste
statutes and regulations and clarifies
which of these provisions are included
in the authorized and federally
enforceable program. By codifying
Oklahoma’s authorized program and by
amending the Code of Federal
Regulations, the public will be more
easily able to discern the status of
federally approved requirements of the
Oklahoma hazardous waste
management program.

II. What are the background and purpose of this NODA?
On February 3, 2014, at 79 FR 6330, the EPA proposed to amend
standards of performance for New Residential Wood Heaters and to add
two new subparts: Standards of Performance for New Residential Hydronic
Heaters and Forced-Air Furnaces and Standards of Performance for New
Residential Masonry Heaters. The EPA is issuing this NODA in support of
the proposed standards. Through this NODA, the EPA is making available
to the public, and soliciting comment on, additional information on
residential wood heater testing and certification that has been added
to the docket for the proposed rule. Specifically, we are making
available the following: (1) Additional details of certification
testing (using crib wood) of wood stoves and pellet stoves certified by
the EPA between January 1, 2010, and May 30, 2014; (2) details of cord
wood testing by two manufacturers of their EPA-certified catalytic wood
stoves; and (3) details of cord wood testing by Brookhaven National
Laboratory (BNL), under contract to the EPA, of an EPA-certified
noncatalytic wood stove.
1. Additional Details of Certification Testing (using crib wood) of
Wood Stoves and Pellet Stoves Certified by EPA between January 1, 2010
and May 30, 2014. All EPA-certified wood heaters that are offered or
advertised for sale in the United States are subject to the current
(1988) New Source Performance Standard (NSPS) for New Residential Wood
Heaters under the Clean Air Act (40 CFR part 60, subpart AAA). These
EPA-certified appliances are required to meet the particulate emissions
limit of 7.5 grams per hour (g/hr) for non-catalytic wood heaters and
4.1 g/hr for catalytic wood heaters.\1\ The model line certifications
are based primarily on testing of representative stoves by EPA-
accredited test laboratories according to EPA Method 28. Method 28 and
the NSPS require testing for each of four burn rate categories.
Category 4 is the maximum burn rate. Category 1 is the minimum burn
rate. Categories 2 and 3 are in between. In the EPA's February 3, 2014,
proposal, we proposed to update and strengthen the existing emission
limits for these wood heaters over a 5-year period. One of the aspects
of the proposal included requiring compliance for each of the
individual burn rates rather than just the weighted average. These
additional data supplement the previous data in the docket, which are
for wood stoves certified prior to January 1, 2010.
---------------------------------------------------------------------------
\1\ Under state law, wood stoves offered for sale in the state
of Washington must meet a particulate emissions limit of 4.5 g/hr
for non-catalytic wood stoves and 2.5 g/hr for catalytic wood
stoves.
---------------------------------------------------------------------------
As of May 30, 2014, the EPA has certified approximately 1,000 wood
and pellet stove model lines that comply with the current NSPS. Summary
information, including weighted emission averages, for these stoves is
located at: https://www.epa.gov/Compliance/resources/publications/monitoring/caa/woodstoves/certifiedwood.pdf.
From February 1988 to December 31, 2009, the EPA certified over 900
wood stove model lines. Particulate matter emissions by burn rate for
most of the stoves in production on December 31, 2009, were summarized
by the Hearth, Patio and Barbecue Association (HPBA) in a database for
the EPA and the EPA included it in the docket prior to the February 3,
2014, proposal.
Since December 31, 2009, the EPA has certified over 100 wood stove
model lines that comply with the current NSPS. The EPA is announcing
the availability of detailed emissions data for each of these model
lines certified since December 31, 2009. Manufacturers and laboratories
previously used all-encompassing CBI claims to restrict public access
to these emission data. The EPA has gone through the official CBI
process to release the emission data.
The following data, for each model line certified since December
31, 2009, are available in the docket for the proposed rule (https://www.regulations.gov/#!docketDetail;D=EPA-HQ-OAR-2009-0734):
Year of certification;
Average weighted emission rate;
Device type (i.e., catalytic stove, non-catalytic stove,
or pellet stove);
EPA test method used (e.g., 5G or 5H); and
Emission results for individual burn categories for all
burn rates--Categories 1, 2, 3 and 4. In some cases, there are multiple
test runs for some burn rate categories.
The EPA asks for comments on these data and how they may influence
the final rule.
2. Details of Cord Wood Testing by Two Manufacturers of Their EPA-
certified Catalytic Wood Stoves. The EPA has received emissions test
data from two catalytic wood stove manufacturers that show their EPA-
certified wood stoves tested using cord wood--and making no design
changes to adjust for crib wood versus cord wood in the tests--have
similar emissions as stoves tested using crib wood. That is, the test
data for an EPA-
[[Page 37261]]
certified Woodstock Soapstone stove and two EPA-certified stoves
produced by another manufacturer show particulate emission rates (g/hr)
using cord wood that are equal to or less than the corresponding test
data using crib wood for all burn rates. The EPA asks for comments on
these data and how they may influence the final rule.
3. Details of Cord Wood Testing by Brookhaven National Laboratory
(BNL), under Contract to the EPA, of an EPA-certified Noncatalytic Wood
Stove. Numerous comments on the February 3, 2014, proposal suggest that
manufacturers tune their stoves to the EPA crib wood certification test
method and that they would need to re-tune their stoves for the
proposed Step 2 cord wood certification test method. We believe this is
true and that manufacturers will soon 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 for crib wood versus cord wood. However, numerous non-catalytic
stove manufacturers have indicated that they are waiting for the
proposed NSPS revisions to become final before they undergo the expense
of such testing. At this time, no manufacturer has submitted
particulate matter emissions test data for non-catalytic wood stoves
tuned to burn cord wood during tests similar to the EPA certification
tests or the ASTM (formerly known as the American Society for Testing
and Materials) draft cord wood test method.
In June 2014, BNL (under an EPA contract) conducted new emissions
testing of a popular non-catalytic EPA-certified wood stove using cord
wood. Existing EPA certification test data for crib wood based on the
current EPA Test Method 5G (https://www.epa.gov/ttnemc01/promgate/m-05g.pdf) were compared to the new test data for using cord wood (with
no stove design changes). Use of existing crib wood data were used for
the comparison in order to minimize the cost of the additional testing.
We note that this raises the question whether new crib wood testing
would have produced similar results as the previous crib wood testing.
Also, we note that the new cord wood testing was conducted with Method
5H, whereas the previous certification testing was conducted with
Method 5G. The results of the test show:
a. For a popular, current model non-catalytic stove that was not
adjusted by the manufacturer for burning cord wood instead of crib wood
during the certification test, the emission test results can be
significantly higher than the crib emission test results. As discussed
above, the proposed Step 2 reasonably anticipates that the
manufacturers would 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 for cribs
versus cord wood. However, that was not done for this new test series.
b. Repeatability of cord wood test method results can sometimes be
very good. For example, the results for three replicate tests for burn
rate Category 4 (the maximum burn rate) were within 15 percent of each
other.
c. Higher moisture content of the fuel can increase particulate
matter emissions.
The complete BNL test report and summary have been added to the
docket for the proposed rule at: https://www.regulations.gov/#!docketDetail;D=EPA-HQ-OAR-2009-0734. The EPA asks for comments on
these data and how they may influence the final rule.
