Subpart KKKKK--National Emission Standards for Hazardous Air
Pollutants for Clay Ceramics Manufacturing

What This Subpart Covers

Sec.  63.8530  What is the purpose of this subpart?

    This subpart establishes national emission limitations and work
practice standards for hazardous air pollutants (HAP) emitted from clay
ceramics manufacturing facilities. This subpart also establishes
requirements to demonstrate initial and continuous compliance with the
emission limitations and work practice standards.

Sec.  63.8535  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a clay
ceramics manufacturing facility that is, is located at, or is part of a
major source of HAP emissions according to the criteria in paragraphs
(a) and (b) of this section.
    (a) A clay ceramics manufacturing facility is a plant site that
manufactures pressed floor tile, pressed wall tile, other pressed tile,
or sanitaryware (e.g., sinks and toilets). Clay ceramics manufacturing
facilities typically process clay, shale, and various additives; form
the processed materials into tile or sanitaryware shapes; and dry and
fire the ceramic products. Glazes are applied to many tile and
sanitaryware products. A plant site that manufactures refractory
products, as defined in Sec.  63.9824, or brick and structural clay
products (BSCP), as defined in Sec.  63.8515, is not a clay ceramics
manufacturing facility.
    (b) A major source of HAP emissions is any stationary source or
group of stationary sources within a contiguous area under common
control that emits or has the potential to emit any single HAP at a
rate of 9.07 megagrams (10 tons) or more per year or any combination of
HAP at a rate of 22.68 megagrams (25 tons) or more per year.

Sec.  63.8540  What parts of my plant does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed
affected source at a clay ceramics manufacturing facility.
    (b) Each existing, new, or reconstructed ceramic tile roller kiln,
sanitaryware tunnel kiln, sanitaryware shuttle kiln, ceramic tile glaze
line using glaze spraying, sanitaryware glaze spray booth, ceramic tile
spray dryer, and floor tile press dryer is an affected source.
    (c) Process units not subject to the requirements of this subpart
are listed in paragraphs (c)(1) through (9) of this section.
    (1) Tunnel, roller or shuttle kilns that are used exclusively for
refiring.
    (2) Tunnel, roller or shuttle kilns that are used exclusively for
setting glazes on previously fired products.
    (3) Glaze spray operations that are used exclusively with those
kilns listed in paragraphs (c)(1) and (2) of this section.
    (4) Process units listed in paragraphs (c)(1) through (3) of this
section that are permitted to, but do not, process first-fire ware,
until such time as they begin to process first-fire ware.
    (5) Glaze spray operations that on average use wet glazes
containing less than 0.1 (weight) percent metal HAP (dry weight basis)
per spray booth over an entire calendar year.
    (6) Raw material processing and handling.
    (7) Wall tile press dryers.
    (8) Sanitaryware ware dryers.
    (9) Sources covered by subparts JJJJJ and SSSSS of this part.
    (d) A source is a new affected source if construction of the
affected source began after December 18, 2014, and you met the
applicability criteria at the time you began construction.
    (e) An affected source is reconstructed if you meet the criteria as
defined in Sec.  63.2.
    (f) An affected source is existing if it is not new or
reconstructed.

Sec.  63.8545  When do I have to comply with this subpart?

    (a) You must comply with this subpart no later than the compliance
dates in Table 8 to this subpart.
    (b) You must meet the notification requirements in Sec.  63.8630
according to the schedule in Sec.  63.8630 and in subpart A of this
part. Some of the notifications must be submitted before you are
required to comply with the emission limitations in this subpart.

Emission Limitations and Work Practice Standards

Sec.  63.8555  What emission limitations and work practice standards
must I meet?

    (a) You must meet each emission limit in Table 1 to this subpart
that applies to you.
    (b) You must meet each operating limit in Table 2 to this subpart
that applies to you.
    (c) You must meet each work practice standard in Table 3 to this
subpart that applies to you.

Sec.  63.8560  What are my options for meeting the emission limitations
and work practice standards?

    (a) To meet the emission limitations in Tables 1 and 2 to this
subpart, you must use one or more of the options listed in paragraphs
(a)(1) and (2) of this section.
    (1) Emissions control system. Use an emissions capture and
collection system and an air pollution control device (APCD) and
demonstrate that the resulting emissions meet the emission limits in
Table 1 to this subpart, and that the capture and collection system and
APCD meet the applicable operating limits in Table 2 to this subpart.
    (2) Process changes. Use low-HAP raw materials or implement
manufacturing process changes and demonstrate that the resulting
emissions or emissions reductions meet the emission limits in Table 1
to this subpart.
    (b) To meet the work practice standards for affected sanitaryware
shuttle kilns, you must comply with the requirements listed in Table 3
to this subpart.
    (c) To meet the work practice standards for affected sources during
periods of startup and shutdown, you must comply with the requirements
listed in Table 3 to this subpart.

General Compliance Requirements

Sec.  63.8570  What are my general requirements for complying with this
subpart?

    (a) You must be in compliance with the emission limitations
(including operating limits) in this subpart at all times, except
during periods that you are approved for and in compliance with the
alternative standard for routine control device maintenance as
specified in paragraph (d) of this section, and except during periods
of start-up and shutdown, at which time you must comply with the
applicable work practice standard specified in Table 3 to this subpart.
    (b) At all times, you must operate and maintain any affected
source, including

associated air pollution control equipment and monitoring equipment, in
a manner consistent with safety and good air pollution control
practices for minimizing emissions. The general duty to minimize
emissions does not require you to make any further efforts to reduce
emissions if levels required by the applicable standard have been
achieved. Determination of whether a source is operating in compliance
with operation and maintenance requirements will be based on
information available to the Administrator which may include, but is
not limited to, monitoring results, review of operation and maintenance
procedures, review of operation and maintenance records, and inspection
of the source. During the period between the compliance date specified

activities, describe the maintenance activities and the frequency of
the maintenance activities, explain why the maintenance cannot be
accomplished during source shutdowns, provide information stating
whether the continued operation of the affected source will result in
fewer emissions than shutting the source down while the maintenance is
performed, describe how you plan to comply with paragraph (b) of this

    (iii) If you have a single tunnel or roller kiln at your facility
and the total facility maximum potential HCl-equivalent emissions
(Emax total) are greater than the HCl-equivalent limit in

Table 1 to this subpart, you must determine the maximum process rate
for the kiln using Equation 8 that would ensure the total facility
maximum potential HCl-equivalent emissions remain at or below the HCl-
equivalent limit. The maximum process rate would become your operating
limit for process rate and must be included in your OM&M plan.

(Emax total) are greater than the HCl-equivalent limit in
Table 1 to this subpart, you must determine the combination of maximum
process rates that would ensure that total facility maximum potential
HCl-equivalent remains at or below the HCl-equivalent limit. The
maximum process rates would become your operating limits for process
rate and must be included in your OM&M plan.
