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.

I. General Information

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has since been replaced by the Brick and Structural Clay Products 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).

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).

    The revision and additions read as follows:

Sec.  63.8620  How do I demonstrate continuous compliance with the 
emission limitations and work practice standards?

* * * * *
    (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.

and first-fire glaze sprayed (dry weight basis) for existing tile 
glaze lines with glaze spraying and average weighted emissions for 
PM, in units of kilograms (pounds) per megagram (ton) of first-fire 
glaze sprayed (dry weight basis) for existing sanitaryware manual, 
spray machine, or robot glaze applications, for that calendar month.
Ei = Emission rate (as determined during the most recent 
compliance demonstration) of PM or mercury from unit i, in units of 
kilograms (pounds) per megagram (ton). Determine the emission rate

this subpart using the applicable equation in Sec.  63.8595(f).
Pmonth i = The process rate for that calendar month for 
unit i, in units of megagrams (tons).
n = Number of units participating in the emissions averaging option.

    (2) Until 12 monthly weighted average emission rates have been 
accumulated, calculate and report only the average weighted emission 
rate determined under paragraph (f)(1)(ii) of this section for each 
calendar month. After 12 monthly weighted average emission rates have 
been accumulated, for each subsequent calendar month, use Equation 11 
of this section to calculate the 12-month rolling average of the 
monthly weighted average emission rates for the current calendar month 
and the previous 11 calendar months.
