National Emission Standards for Hazardous Air Pollutants for Clay
Ceramics Manufacturing
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action finalizes certain amendments to the National
Emission Standards for Hazardous Air Pollutants (NESHAP): Clay Ceramics
Manufacturing source category. The final amendments are being issued in
response to a petition for reconsideration filed by an affected
industry (Kohler Company) on the final rule promulgated on October 26,
2015, as well as our review of the 2015 rule with respect to certain
other issues raised by Kohler. This action revises the temperature
monitoring methodology used to demonstrate continuous compliance with
the dioxin/furan (D/F) emissions limit of the final rule. In addition,
we are addressing concerns raised by Kohler regarding visible emissions
(VE) monitoring of tunnel kiln stacks for continuous compliance with
particulate matter (PM) and mercury (Hg) emission limitations. This
action also amends the requirements for weekly visual inspections of
system ductwork and control device equipment for water curtain spray
booths. Lastly, this action amends the NESHAP to include provisions for
emissions averaging, makes technical corrections, and adds certain
definitions.
DATES: This final rule is effective on November 1, 2019.

A. Does this action apply to me?
Table 1 of this preamble lists the NESHAP and associated regulated
industrial source categories that are the subject of this final action.
Table 1 is not intended to be exhaustive but rather provides a guide
for readers regarding the entities that this final action is likely to
affect. The final amendments will be directly applicable to the
affected sources. Federal, state, local and tribal government entities
would not be affected by this final action. As defined in the Initial
List of Categories of Sources Under Section 112(c)(1) of the Clean Air
Act Amendments of 1990 (see 57 FR 31576, July 16, 1992) and
Documentation for Developing the Initial Source Category List (see EPA-
450/3-91-030), the Clay Products Manufacturing source category as
originally listed included any facility engaged in manufacturing of
clay products such as brick, vitrified clay pipe, structural clay tile,
and clay refractories. The Clay Products Manufacturing source category
has since been replaced by the Brick and Structural Clay Products
(BSCP) Manufacturing source category and the Clay Ceramics
Manufacturing source category (see 67 FR 47894, July 22, 2002).

[[Page 58603]]
C. Judicial Review and Administrative Reconsideration
Under Clean Air Act (CAA) section 307(b)(1), judicial review of
this final action is available only by filing a petition for review in
the United States Court of Appeals for the District of Columbia Circuit
by December 31, 2019. Under CAA section 307(b)(2), the requirements
established by this final rule may not be challenged separately in any
civil or criminal proceedings brought by the EPA to enforce the
requirements.
Section 307(d)(7)(B) of the CAA further provides that only an
objection to a rule or procedure which was raised with reasonable
specificity during the period for public comment (including any public
hearing) may be raised during judicial review. This section also
provides a mechanism for the EPA to reconsider the rule if the person
raising an objection can demonstrate to the Administrator 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 should submit a
Petition for Reconsideration to the Office of the Administrator, U.S.
EPA, Room 3000, WJC South Building, 1200 Pennsylvania Ave. NW,
Washington, DC 20460, with a copy to both the person 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
A. What is the statutory authority for this action?
The statutory authority for this action is provided by sections 112
and 307(d)(7)(B) of the CAA as amended (42 U.S.C. 7412 and
7607(d)(7)(B)).
B. What actions preceded these final amendments?
The initial NESHAP for Clay Ceramics Manufacturing was published in
the Federal Register on May 16, 2003 (68 FR 26690), and codified at 40
CFR part 63, subpart KKKKK, pursuant to section 112 of the CAA. These
standards were challenged and subsequently vacated by the United States
Court of Appeals for the District of Columbia Circuit in 2007. See
Sierra Club v. EPA, 479 F.3d 875, 876 (D.C. Cir. 2007). Following the
2007 vacatur of the 2003 rule, the EPA collected additional data and
information to support new standards for the clay ceramics industry.
This information is contained in the docket at https://www.regulations.gov/ (see Docket ID No. EPA-HQ-OAR-2013-0290). On
December 18, 2014, the EPA proposed the new NESHAP for Clay Ceramics
Manufacturing (79 FR 75622). The EPA received additional data and
comments during the public comment period. These data and comments were
considered and analyzed and, where appropriate, revisions to the NESHAP
were made. The NESHAP for Clay Ceramics Manufacturing was finalized on
October 26, 2015 (80 FR 65470).
On December 23, 2015, Kohler Company (Kohler) petitioned the EPA
for reconsideration of the final rule for Clay Ceramics Manufacturing
(Docket ID No. EPA-HQ-OAR-2013-0290-0316). On August 20, 2018, we
proposed revisions to the Clay Ceramics Manufacturing NESHAP based on
the information provided by Kohler in their petition and information
collected by the EPA (83 FR 42066). Public comments were received on
the proposal requesting some changes to the proposed revisions. This
action finalizes the revisions to the NESHAP and, where deemed
appropriate, incorporates the requested changes. The intent of these
amendments is to provide flexibility to the clay ceramics manufacturing
industry, while maintaining the emissions and operational standards of
the NESHAP.
III. Summary of the Final Amendments
The EPA is issuing the following amendments to 40 CFR part 63,
subpart KKKKK, in response to Kohler's petition for reconsideration on
the October 26, 2015, final rule (80 FR 65470):
Revise the temperature monitoring methodology used to
demonstrate continuous compliance with the D/F emissions limits from
sanitaryware first-fire tunnel kilns;
Provide an alternative to the monitoring provisions for VE
from tunnel kiln exhaust stacks;
Amend the requirements for weekly visual inspections of
system ductwork and control device equipment for water curtain spray
booths;
Define cooling stacks in the rule and differentiate
cooling stacks from kiln exhaust stacks for compliance purposes; and
Include provisions to allow emissions averaging for
emissions from existing tunnel kilns and glaze spray booths and make
associated revisions to the definition of affected source and
recordkeeping and reporting requirements.
We are finalizing all the amendments listed above as proposed except
for the provisions to allow emissions averaging. A description of the
changes made to the emissions averaging provisions since proposal along
with the rationale for those changes is provided in section IV of this
preamble.
This final rule achieves meaningful burden reduction by providing
regulated facilities with the ability to use existing monitoring
equipment and removing the requirements for periodic inspections that
we have determined are not necessary to demonstrate compliance. We also
more clearly identify which stacks are cooling stacks; thus, avoiding
the possibility that a source might be required to perform an emission
test on a stack that emits only cooling air. Finally, this action
provides additional compliance flexibility for sources to meet certain
emissions limits by averaging; thereby, simplifying compliance. All of
these actions should reduce the overall burden to the regulated
sources.
This action is limited to the specific issues raised in the
petition for reconsideration, plus some minor technical corrections.
There are no changes to emission limits as a result of these final
amendments. Technical corrections are being issued as proposed to
correct inaccuracies that were promulgated in the final rule, replace
text that might be considered confusing, and correct outdated
information. These changes are described in Table 2 of this preamble.

------------------------------------------------------------------------
IV. Rationale for Changes to the Proposed Amendments
A. Visible Emissions Monitoring of Tunnel Kiln Exhaust
In its petition for reconsideration, Kohler stated that the EPA
failed to adequately respond to Kohler's public comments regarding VE
monitoring in the Agency's response to comments document and in the
preamble for the final rule. In their comments on the December 18,
2014, proposal, Kohler had argued that VE monitoring is not a useful
parameter to assess kiln operation nor to assess hazardous air
pollutant (HAP) emissions. Kohler requested that the EPA open a new
public comment period to reconsider and respond to Kohler's concerns.
In response to the petition, we proposed amendments to 40 CFR 63.8620
in the Clay Ceramics Manufacturing NESHAP, adding a new paragraph
(e)(2) which provided an alternative to VE testing that allowed sources
to demonstrate compliance by maintaining the kiln temperature profile
within acceptable parameters and, for any incidence where the kiln
exceeds its temperature profile, monitor VE at each kiln stack as
specified.
In public comments on the proposed amendments, a commenter
questioned Kohler's assertion about VE monitoring and recommended that
the EPA define what a ``temperature profile'' is and clarify what it
means to ``maintain'' it v. ``exceed'' it. In response to this comment,
we are finalizing amendments to 40 CFR 63.8620(e)(2), the operating
limits table (Table 2), and the continuous compliance table (Table 7)
to clarify that the owner or operator will be required to maintain
their kiln operating temperature within the range of acceptable
temperatures (i.e., a temperature profile) established for each kiln
and product. For any incident where the kiln is operating outside of
its acceptable temperature range (i.e., exceeding its temperature
profile) for the product being fired, the owner or operator will be
required to record the incident as a deviation, and perform corrective
action in accordance with the facility's operation, maintenance, and
monitoring (OM&M) plan.
B. Weekly Visual Inspections of Water Curtain Spray Booths
In its petition for reconsideration, Kohler requested that the EPA
reconsider the frequency of visual inspection requirements for system
ductwork and control device equipment for water curtain spray booths.
In response to the petition, we proposed amendments to the operating
limits table (Table 2) and the continuous compliance table (Table 7) to
remove the requirement to conduct weekly visual inspections of the
system ductwork and control equipment for leaks for all glaze spray
operations equipped with water curtains.
In public comments on the proposal, one commenter stated that if
the EPA is relying on operator observations of visible particulate on
the product to determine when there is a leak in the spray booth
ductwork, the rule should require operators to log such incidents and
report them as deviations when they occur. We recognize the commenter's
concerns and agree that if there is an indication of particulate in the
glaze of the product, then it is likely there is a failure in the
ductwork requiring corrective action, and, therefore, this would be
considered a deviation. We are finalizing amendments to Table 7 to
require owners or operators to record as deviations any observations of
particulates or other impurities getting into the glaze that has been
sprayed onto a piece of ware and perform corrective action in
accordance with the facility's OM&M plan.
C. Emissions Averaging
In its petition for reconsideration, Kohler requested that the EPA
allow the use of emissions averaging as a compliance option in the Clay
Ceramics Manufacturing NESHAP for existing tunnel kilns and glaze spray
booths. In response to the petition, we proposed amendments to 40 CFR
63.8595 in the Clay Ceramics Manufacturing NESHAP that included
alternative emissions averaging limits for the following:
PM and Hg, in units of pounds per ton (lb/ton) of fired
product for existing floor tile roller kilns;
PM and Hg in units of lb/ton of fired product for existing
wall tile roller kilns;
PM and Hg, in units of lb/ton of greenware fired for
existing first-fired sanitaryware tunnel kilns;
PM and Hg, in units of lb/ton of first-fired glaze sprayed
(dry weight basis) for existing tile glaze lines with glaze spraying;
and
PM, in units of lb/ton of first-fire glaze sprayed (dry
weight basis), for existing sanitaryware manual, spray machine, or
robot glaze applications.
The proposed conditions required for emissions averaging included
the following: (1) Emissions averaging would only be permitted between
individual sources at a single existing affected source; (2) emissions
averaging would only be permitted between individual sources subject to
the Clay Ceramics Manufacturing NESHAP; (3) emissions averaging would
not be permitted between two or more different affected sources; (4)
emissions averaging would not be permitted between two or more sources
in different subcategories;
[[Page 58605]]
(5) new sources could not use emissions averaging; and (6) averaged
emissions could not exceed 90 percent of the applicable emission limit,
which translates to a discount factor of 1.1 applied to actual
emissions.
The emissions averaging provisions that we proposed were based, in
part, on the emissions averaging provisions in the Hazardous Organic
NESHAP (HON). The legal basis and rationale for the HON emissions
averaging provisions were provided in the preamble to the final HON (59
FR 19425, April 22, 1994).
In public comments on the proposal, two commenters requested that
the EPA remove the requirement that averaged emissions cannot exceed 90
percent of the applicable emission limit, and a third commenter stated
that no justification was provided for the selection of 90 percent
(instead of an alternate value, such as 80 or 99 percent). While
averaging should only be permitted if it can be demonstrated that the
total quantity of any HAP will not be greater than it could be if each
individually affected unit complied separately with the applicable
standard, one commenter stated this requirement can be demonstrated
without the ``90 percent of the limit'' safety factor. The commenter
noted that the EPA has allowed emissions averaging across similar
emission units in other NESHAP, such as the Reinforced Plastics
Composites NESHAP (40 CFR part 63, subpart WWWW), and stated that
similar logic for averaging should be applied to this subpart to
eliminate the unnecessary factor.
In response to these comments, we have re-evaluated whether a
discount factor is appropriate for the emissions averaging provisions
in this subpart and have concluded that a discount factor is not
necessary here. The issues faced in the HON, where a discount factor of
1.1 was applied to the emissions averaging calculation, included
significant differences in toxicity of the various HAP and a situation
where facilities were applying emissions controls. This is not the case
here. All facilities are meeting the relevant standards in this subpart
without added controls and are using pollution prevention where needed.
Accordingly, a straight average, without any discount factor, is
appropriate in this situation. This straight-average approach is
consistent with other rules, such as the Reinforced Plastic Composites
NESHAP. Therefore, the EPA has decided not to include a discount factor
in 40 CFR 63.8595(h), Equation 9, and 40 CFR 63.8620, Equation 10 to
calculate the average weighted emissions.
In addition, a commenter noted that the proposed emissions
averaging provisions prohibited emissions averaging of new sources but
did not prohibit emissions averaging of reconstructed sources. The
commenter stated that reconstructed sources should not be allowed to
use the emissions averaging provisions. We agree with the commenter,
and in the final amendments the EPA has revised 40 CFR 63.8595(h)(1) to
indicate that neither new nor reconstructed sources can be included in
the emissions averaging.
Finally, we note that Equations 9 through 11 were all proposed to
be added to 40 CFR 63.8595(h). However, one commenter noted an apparent
discrepancy between Equation 9 and Equation 10, and it appears that the
commenter misunderstood that Equation 9 is intended to determine
initial compliance based on an initial performance test, while Equation
10 is intended to determine ongoing compliance based on the latest
performance test. Equation 11 is also used for ongoing compliance and
is intended to determine the 12-month rolling average of the monthly
weighted average emission rates. Therefore, in the final amendments,
Equations 10 and 11 have been moved to 40 CFR 63.8620, the section that
describes how to demonstrate continuous compliance.
V. Summary of Cost, Environmental, and Economic Impacts
This action will have no cost, environmental, energy, or economic
impacts beyond those impacts presented in the October 26, 2015, final
rule for Clay Ceramics Manufacturing and may result in a cost savings
due to the changes in monitoring and testing requirements discussed in
section III of this preamble. The technical corrections are cost
neutral.
VI. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action and was,
therefore, not submitted to the OMB for review.
B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs
This action is considered an Executive Order 13771 deregulatory
action. This final rule provides meaningful burden reduction by
providing additional regulatory flexibilities.
C. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the existing regulation (40 CFR part 63,
subpart KKKKK) and has assigned OMB control number 2060-0513. This
action does not change the information collection requirements.
D. Regulatory Flexibility Act (RFA)
I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. In
making this determination, the impact of concern is any significant
adverse economic impact on small entities. An agency may certify that a
rule will not have a significant economic impact on a substantial
number of small entities if the rule relieves regulatory burden, has no
net burden, or otherwise has a positive economic effect on the small
entities subject to the rule. This final rule will not impose any
additional requirements on small entities, only alternatives to
existing requirements. We have, therefore, concluded that this action
will have no net regulatory burden for all directly regulated small
entities.
E. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate as described in
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect
small governments. The action imposes no enforceable duty on any state,
local, or tribal governments or the private sector.
F. 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.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive
[[Page 58606]]
Order 13175. It will neither impose substantial direct compliance costs
on federally recognized tribal governments, nor preempt tribal law. The
final amendments impose no requirements on tribal governments. Thus,
Executive Order 13175 does not apply to this action.
H. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. This action is not subject to
Executive Order 13045 because it does not concern an environmental
health risk or safety risk.
I. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.
J. National Technology Transfer and Advancement Act (NTTAA)
This rulemaking does not involve technical standards.
K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
The EPA believes that this action does not have disproportionately
high and adverse human health or environmental effects on minority
populations, low-income populations, and/or indigenous peoples, as
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The
documentation for this decision is contained in the docket. (See EJ
Screening Report for Clay Ceramics, Docket ID Item No. EPA-HQ-OAR-2013-
0290-0241.)
L. 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 not a ``major rule'' as defined by 5
U.S.C. 804(2).

(e)(1) Visible emissions testing. You must demonstrate continuous
compliance with the operating limits in Table 2 to this subpart for
visible emissions (VE) from tunnel or roller kilns that are
uncontrolled or equipped with DIFF, DLS/FF, or other dry control device
by monitoring VE at each kiln stack according to the requirements in
paragraphs (e)(1)(i) through (iii) of this section.

(2) Alternative to VE testing. You must demonstrate continuous
compliance with the operating limits in Table 2 to this subpart for
kiln temperature profile for tunnel or roller kilns that are
uncontrolled or equipped with DIFF, DLS/FF, or other dry control device
by maintaining the kiln operating temperature within the range of
acceptable temperatures (i.e., temperature profile) established for
each kiln and product. For any incidence where the kiln is operating
outside of its acceptable temperature range (i.e., exceeds its
temperature profile) for the product being fired, you must record the
incident as a deviation, and perform the necessary corrective action in
accordance with your OM&M plan to return the kiln to the acceptable
operating temperature for the product being fired. To confirm the kiln
has returned to the acceptable temperature range, you will monitor VE
at the kiln stack according to the requirements in paragraphs (e)(2)(i)
through (iii) of this section.
(i) Perform VE observations at the stack of each kiln operating
outside of its temperature profile according to the procedures of
Method 22 of 40 CFR part 60, appendix A-7. The duration of each Method
22 test must be at least 15 minutes.
(ii) If VE are observed during any test conducted using Method 22
of 40 CFR part 60, appendix A-7, you must continue to perform
corrective action until VE are no longer observed.
(iii) If VE are observed during any test conducted using Method 22
of 40 CFR part 60, appendix A-7, you must report these deviations by
following the requirements in Sec. 63.8635.
(f) Following the compliance date, you must demonstrate compliance
with the emissions averaging provision under this subpart on a
continuous basis by meeting the requirements of paragraphs (f)(1)
through (3) of this section.
(1)(i) After the initial compliance demonstration described in
Sec. 63.8595(h)(4), you must demonstrate compliance on a monthly basis
determined at the end of every month (12 times per year) according to
paragraph (f)(1)(ii) of this section. The first monthly period begins
on the compliance date specified in Sec. 63.8545.
(ii) For each calendar month, you must use Equation 10 of this
section to calculate the average weighted emission rate for that month.
