entities, the EPA underestimated the cost for a facility to become a
synthetic area source, and the EPA has underestimated the cost to
comply with the Hg standards given the limited information the agency
has on the performance of Hg controls in this industry.
    Response: The EPA standard engineering cost practice is to
annualize over the expected life of the control equipment at 7 percent.
The EPA does not have the data available to model the way a firm pays
for an APCD because each firm has a different set of potential options
for financing including debt financing, equity financing, and financing
through retained earnings. The EPA acknowledges that some firms may not
be able to borrow the money and some may close. The EPA's closure
analysis is quite uncertain, but we do not have the detailed firm-
specific information necessary to refine the analysis. The EPA agrees
that the costs to become a synthetic area source at proposal were
underestimated, and the final rule impacts include testing costs for
all facilities, as potential synthetic area sources would have to
demonstrate that their emissions qualify them to apply for synthetic
area status. Finally, the EPA must use the best information available
to the agency to estimate the impact of the standards on all entities.
The final Hg standards incorporate variability in the Hg content of raw
materials, which is expected to ease the burdens on some small
entities.
5. Affected Small Entities
    Of 44 parent companies owning BSCP facilities, 36 parent companies
are small businesses. The EPA computed the ratio of estimated
compliance costs to company sales (cost-to-sales ratio) to measure the
magnitude of potential impacts on small companies. Under the final
standards, the EPA estimated that two to three small BSCP manufacturing
facilities (two to four BSCP manufacturing facilities overall) are at
significant risk of closure.
6. Reporting, Recordkeeping, and Other Compliance Requirements
    Respondents would be required to provide one-time and periodic
notifications, including initial notification, notification of
performance tests, and notification of compliance status. Respondents
would also be required to submit semiannual reports documenting
compliance with the rule and detailing any compliance issues, and they
would be required to submit the results of performance tests to the
EPA's ERT. Respondents would be required to keep documentation
supporting information included in these notifications and reports, as
well as records of the operation and maintenance of affected sources
and APCD at the facility.
7. Significant Alternatives
    The EPA considered three major options for this final rule; see
``Regulatory Impact Analysis: Final Brick and Structural Clay Products
NESHAP,'' in Docket ID No. EPA-HQ-OAR-2013-0291), for more information
about the alternatives. Finalizing the proposed changes without
revision is expected to have similar cost and emission reduction
impacts to the standards the EPA is finalizing, with a similar number
of closures (one to two small BSCP manufacturing facilities rather than
two to three). However, for the various legal and technical reasons
outlined in this preamble and ``National Emission Standards for
Hazardous Air Pollutants for Brick and Structural Clay Products
Manufacturing: Background Information for Final Rule--Summary of Public
Comments and Responses'' in Docket ID No. EPA-HQ-OAR-2013-0291, the EPA
determined that the PM/non-Hg HAP metals and Hg standards should not be
finalized as proposed. The other alternative considered included the
same standards for acid gases and Hg that are being finalized but only
provided one set of limits PM/non-Hg HAP metals (i.e., did not provide
separate sets of limits for small and large tunnel kilns). This
alternative is expected to have significantly higher cost impacts than
the standards the EPA is finalizing, along with a significantly higher
number of closures (five to 10

small BSCP manufacturing facilities rather than two to three small BSCP
manufacturing facilities). Therefore, the EPA determined that it is
necessary to exercise its discretion to subcategorize by kiln size to
minimize the significant economic impact on small entities.
    In addition, the EPA is preparing a Small Entity Compliance Guide
to help small entities comply with this rule. The guide will be
available on the World Wide Web approximately 1 year after promulgation
of the rule, at http://www.epa.gov/ttn/atw/brick/brickpg.html.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or
more as described in the UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. This action imposes
no enforceable duty on any state, local, or tribal governments or the
private sector.

E. 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.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

    This action does not have tribal implications, as specified in
Executive Order 13175. It will not have substantial direct effects on
tribal governments, on the relationship between the federal government
and Indian tribes, or on the distribution of power and responsibilities
between the federal government and Indian tribes, as specified in
Executive Order 13175. The action imposes requirements on owners and
operators of BSCP and clay ceramics manufacturing facilities and not
tribal governments. Thus, Executive Order 13175 does not apply to this
action.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because the EPA
does not believe the environmental health risks or safety risks
addressed by this action present a disproportionate risk to children.
This action's health and risk assessments are contained in the
memoranda ``Risk Assessment to Determine a Health-Based Emission
Limitation for Acid Gases for the Brick and Structural Clay Products
Manufacturing Source Category,'' Docket Item No. EPA-HQ-OAR-2013-0291-
0132 and ``Risk Assessment to Determine a Health-Based Emission
Limitation for Acid Gases for the Clay Ceramics Manufacturing Source
Category,'' Docket Item No. EPA-HQ-OAR-2013-0290-0213.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use

    This action is not a ``significant energy action'' because it is
not likely to have a significant adverse effect on the supply,
distribution, or use of energy. This action will not adversely directly
affect productivity, competition, or prices in the energy sector.

I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR
Part 51

    This action involves technical standards. The EPA has decided to
use the following four voluntary consensus standards as acceptable
alternatives to the EPA test methods for the purpose of this rule.
    The EPA has decided to use ANSI/ASME PTC 19.10-1981, ``Flue and
Exhaust Gas Analyses,'' for its manual methods of measuring the oxygen
or carbon dioxide content of the exhaust gas. This standard is
acceptable as an alternative to Method 3A and 3B and is available from
the American Society of Mechanical Engineers (ASME) at http://www.asme.org; by mail at Three Park Avenue, New York, NY 10016-5990; or
by telephone at<PHONE_NUMBER>.
    The EPA has also decided to use ASTM D6735-01 (Reapproved 2009),
``Standard Test Method for Measurement of Gaseous Chlorides and
Fluorides from Mineral Calcining Exhaust Sources--Impinger Method,''
for its measurement of the concentration of gaseous HCl and HF and
other gaseous chlorides and fluorides. This standard is acceptable as
an alternative to Methods 26 and 26A.
    In addition, the EPA has decided to use ASTM D6784-02 (Reapproved
2008), ``Standard Test Method for Elemental, Oxidized, Particle-Bound
and Total Mercury Gas Generated from Coal-Fired Stationary Sources
(Ontario Hydro Method),'' for its determination of elemental, oxidized,
particle-bound, and total Hg emissions. This standard is acceptable as
an alternative to Method 29 (portion for Hg only).
    Finally, the EPA has decided to use ASTM D6348-03 (Reapproved
2010), ``Standard Test Method for Determination of Gaseous Compounds by
Extractive Direct Interface Fourier Transform Infrared (FTIR)
Spectroscopy,'' for its use of an extractive sampling system to direct
stationary source effluent to an FTIR spectrometer for the
identification and quantification of gaseous compounds. This standard
is acceptable as an alternative to Method 320 with the following
conditions: (1) The test plan preparation and implementation in the
Annexes to ASTM D 6348-03, Sections A1 through A8 are mandatory; and
(2) in ASTM D6348-03 Annex A5 (Analyte Spiking Technique), the percent
recovery (%R) must be determined for each target analyte (Equation
A5.5). In order for the test data to be acceptable for a compound, %R
must be greater than or equal to 70 percent and less than or equal to
130 percent. If the %R value does not meet this criterion for a target
compound, the test data are not acceptable for that compound and the
test must be repeated for that analyte (i.e., the sampling and/or
analytical procedure should be adjusted before a retest). The %R value
for each compound must be reported in the test report and all field
measurements must be corrected with the calculated %R value for that
compound by using the following equation: Reported Result = (Measured
Concentration in the Stack x 100)/%R.
    The standards ASTM D6735-01, ASTM D6784-02, and ASTM D6348-03 are
available from the American Society of Testing and Materials (ASTM) at
http://www.astm.org; by mail at 100 Barr Harbor Drive, Post Office Box
C700, West Conshohocken, PA 19428-2959; or by telephone at (610) 832-
9585.
    While the EPA identified ASTM D7520-13, ``Standard Test Method for
Determining the Opacity in a Plume in an Outdoor Ambient Atmosphere''
as being potentially applicable as an alternative to Method 9 for
measuring opacity from BSCP tunnel kilns, the agency decided not to use
it. The use of this voluntary consensus standard would be impractical.
The five provisions for the use of this standard appear to be based on
the assumption that the optical camera will be used on a daily basis.
However, this rulemaking does not include daily Method 9 tests. The
rule requirements are such that a Method 9 observation would need to be
made unexpectedly and only when the Method 22 test failed. It would be
unreasonable to expect that a source would be making daily calibrations
of the camera when its use would be so infrequent. Given that, it is
unlikely that the camera could be made ready in the time specified for
the Method 9

readings. Therefore, this standard is not usable based on the current
requirements in this rulemaking.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income,
or indigenous populations because it does not affect the level of
protection provided to human health or the environment. As explained in
the December 2014 proposal (79 FR 75672), the EPA determined that this
final rule will not have disproportionately high and adverse human
health or environmental effects on minority or low-income populations,
because it increases the level of environmental protection for all
affected populations without having any disproportionately high and
adverse human health or environmental effects on any population,
including any minority or low-income population. Additionally, the
agency has conducted a proximity analysis for this rulemaking, which is
located in the docket. (See ``EJ Screening Report for Brick and
Structural Clay,'' Docket Item No. EPA-HQ-OAR-2013-0291-0102, and ``EJ
Screening Report for Clay Ceramics,'' Docket Item No. EPA-HQ-OAR-2013-
0290-0241.)

K. 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 a ``major rule'' as defined by 5
U.S.C. 804(2).

Subpart JJJJJ--National Emission Standards for Hazardous Air
Pollutants for Brick and Structural Clay Products Manufacturing

What This Subpart Covers

Sec.  63.8380  What is the purpose of this subpart?

    This subpart establishes national emission limitations for
hazardous air pollutants (HAP) emitted from brick and structural clay
products (BSCP) manufacturing facilities. This subpart also establishes
requirements to demonstrate initial and continuous compliance with the
emission limitations.

Sec.  63.8385  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a BSCP
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 BSCP manufacturing facility is a plant site that manufactures
brick (including, but not limited to, face brick, structural brick, and
brick pavers); clay pipe; roof tile; extruded floor and wall tile; and/
or other extruded, dimensional clay products. Brick and structural clay
products manufacturing facilities typically process raw clay and shale,
form the processed materials into bricks or shapes, and dry and fire
the bricks or shapes. A plant site that manufactures refractory
products, as defined in Sec.  63.9824, or clay ceramics, as defined in
Sec.  63.8665, is not a BSCP 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.  63.8390  What parts of my plant does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed
affected source at a BSCP manufacturing facility.
    (b) For the purposes of this subpart, the affected sources are
described in paragraphs (b)(1) and (2) of this section.
    (1) All tunnel kilns at a BSCP manufacturing facility are an
affected source. For the remainder of this subpart, a tunnel kiln with
a design capacity equal to or greater than 9.07 megagrams per hour (Mg/
hr) (10 tons per hour (tph)) of fired product will be called a large
tunnel kiln, and a tunnel kiln with a design capacity less than 9.07
Mg/hr (10 tph) of fired product will be called a small tunnel kiln.
    (2) Each periodic kiln is an affected source.
    (c) Process units not subject to the requirements of this subpart
are listed in paragraphs (c)(1) through (4) of this section.
    (1) Kilns that are used exclusively for setting glazes on
previously fired products are not subject to the requirements of this
subpart.
    (2) Raw material processing and handling.
    (3) Dryers.
    (4) Sources covered by subparts KKKKK 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.  63.8395  When do I have to comply with this subpart?

    (a) You must comply with this subpart no later than the compliance
dates in Table 7 to this subpart.
    (b) You must meet the notification requirements in Sec.  63.8480
according to the schedule in Sec.  63.8480 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.  63.8405  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.  63.8410  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 periodic
kilns, you must comply with the requirements listed in Table 3 to this
subpart.
    (c) To meet the work practice standards for dioxins/furans for
affected tunnel kilns, you must comply with the requirements listed in
Table 3 to this subpart.
    (d) To meet the work practice standards for affected tunnel kilns
during periods of startup and shutdown, you must comply with the
requirements listed in Table 3 to this subpart.

General Compliance Requirements

Sec.  63.8420  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
for your affected source in Sec.  63.8395 and the date upon which
continuous monitoring systems (CMS) (e.g., continuous parameter
monitoring systems) have been installed and verified and any applicable
operating limits have been set, you must maintain a log detailing the
operation and maintenance of the process and emissions control
equipment.
    (c) For each affected kiln that is subject to the emission limits
specified in Table 1 to this subpart, you must prepare and implement a
written operation, maintenance, and monitoring (OM&M) plan according to
the requirements in Sec.  63.8425.
    (d) If you own or operate an affected kiln that is subject to the
emission limits specified in Table 1 to this subpart and must perform
routine maintenance on the control device for that kiln, you may bypass
the kiln control device and continue operating the kiln subject to the
alternative standard established in this paragraph upon approval by the
Administrator and provided you satisfy the conditions listed in
paragraphs (d)(1) through (5) of this section.
    (1) You must request to use the routine control device maintenance
alternative standard from the Administrator no later than 120 calendar
days before the compliance date specified in Sec.  63.8395. Your
request must justify the need for the routine maintenance on the
control device and the time required to accomplish the maintenance
activities, describe the maintenance activities and the frequency of
the maintenance activities, explain why the maintenance cannot be
accomplished during kiln 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
section during the maintenance, and provide any other documentation
required by the Administrator.
    (2) The routine control device maintenance must not exceed 4
percent of the annual operating uptime for each kiln.
    (3) The request for the routine control device maintenance
alternative standard, if approved by the Administrator, must be
incorporated by reference in and attached to the affected source's
title V permit.
    (4) You must minimize HAP emissions during the period when the kiln
is operating and the control device is offline by complying with the
applicable standard in Table 3 to this subpart.
    (5) You must minimize the time period during which the kiln is
operating and the control device is offline.
    (e) You must be in compliance with the work practice standards in
this subpart at all times.
    (f) You must be in compliance with the provisions of subpart A of
this part, except as noted in Table 10 to this subpart.

Sec.  63.8425  What do I need to know about operation, maintenance, and
monitoring plans?

    (a) For each affected kiln that is subject to the emission limits
specified in Table 1 to this subpart, you must prepare, implement, and
revise as necessary an OM&M plan that includes the information in
paragraph (b) of this section. Your OM&M plan must be available for
inspection by the delegated authority upon request.
    (b) Your OM&M plan must include, as a minimum, the information in
paragraphs (b)(1) through (13) of this section.
    (1) Each process and APCD to be monitored, the type of monitoring
device that will be used, and the operating parameters that will be
monitored.
    (2) A monitoring schedule that specifies the frequency that the
parameter values will be determined and recorded.
    (3) The limits for each parameter that represent continuous
compliance with the emission limitations in Sec.  63.8405. The limits
must be based on values of the monitored parameters recorded during
performance tests.
    (4) Procedures for the proper operation and routine and long-term
maintenance of each APCD, including a maintenance and inspection
schedule that is consistent with the manufacturer's recommendations.
    (5) Procedures for installing the CMS sampling probe or other
interface at a measurement location relative to each affected process
unit such that the measurement is representative of control of the
exhaust emissions (e.g., on or downstream of the last APCD).

Testing and Initial Compliance Requirements

Sec.  63.8435  By what date must I conduct performance tests?

    For each affected kiln that is subject to the emission limits
specified in Table 1 to this subpart, you must conduct performance
tests within 180 calendar days after the compliance date that is
specified for your source in Sec.  63.8395 and according to the
provisions in Sec.  63.7(a)(2).

Sec.  63.8440  When must I conduct subsequent performance tests?

    (a) For each affected kiln that is subject to the emission limits
specified in Table 1 to this subpart, you must conduct a performance
test before renewing your 40 CFR part 70 operating permit or at least
every 5 years following the initial performance test.
    (b) You must conduct a performance test when you want to change the
parameter value for any operating limit specified in your OM&M plan.

Sec.  63.8445  How do I conduct performance tests and establish
operating limits?

to this subpart.
    (d) Performance tests shall be conducted under such conditions as
the Administrator specifies to you based on representative performance
of the affected source for the period being tested. Representative
conditions exclude periods of startup and shutdown. You may not conduct
performance tests during periods of malfunction. You must record the
process information that is necessary to document operating conditions
during the test and include in such record an explanation to support
that such conditions represent normal operation. Upon request, you
shall make available to the Administrator such records as may be
necessary to determine the conditions of performance tests.

subpart, you must calculate your mass emissions per unit of production
for each test run using Equation 1:
[GRAPHIC] [TIFF OMITTED] TR26OC15.014

Where:

MP = mass per unit of production, kilograms (pounds) of pollutant
per megagram (ton) of fired product
ER = mass emission rate of pollutant (PM or Hg) during each
performance test run, kilograms (pounds) per hour
P = production rate during each performance test run, megagrams
(tons) of fired product per hour.

    (2) To determine compliance with the health-based standard for acid
gas HAP for BSCP manufacturing facilities in Table 1 to this subpart,
you must:
    (i) Calculate the HCl-equivalent emissions for HF, HCl, and
Cl2 for each tunnel kiln at your facility using Equation 2:
[GRAPHIC] [TIFF OMITTED] TR26OC15.015

Where:

Ei = HCl-equivalent emissions for kiln i, kilograms
(pounds) per hour
EHCl = emissions of HCl, kilograms (pounds) per hour
EHF = emissions of HF, kilograms (pounds) per hour
ECl2 = emissions of Cl2, kilograms (pounds)
per hour
RfCHCl = reference concentration for HCl, 20 micrograms
per cubic meter

RfCHF = reference concentration for HF, 14 micrograms per
cubic meter
RfCCl2 = reference concentration for Cl2, 0.15
micrograms per cubic meter

    (ii) If you have multiple tunnel kilns at your facility, sum the
HCl-equivalent values for all tunnel kilns at the facility using
Equation 3:
[GRAPHIC] [TIFF OMITTED] TR26OC15.016

Where:

at facility, kilograms (pounds) per hour
Ei = HCl-equivalent emissions for kiln i, kilograms
(pounds) per hour
n = number of tunnel kilns at facility

    (iii) Compare this value to the health-based standard in Table 1 to
this subpart.

the maximum potential HCl-equivalent emissions for HF, HCl, and
Cl2 for each tunnel kiln at your facility using Equation 4:
[GRAPHIC] [TIFF OMITTED] TR26OC15.017

Where:

Emax i = maximum potential HCl-equivalent emissions for
kiln i, kilograms (pounds) per hour
Capi = design capacity for kiln i, megagrams (tons) of
fired product per hour
MPiHCl = mass of HCl per unit of production for kiln i,
kilograms (pounds) of HCl per megagram (ton) of fired product
MPiHF = mass of HF per unit of production for kiln i,
kilograms (pounds) of HF per megagram (ton) of fired product
MPiCl2 = mass of Cl2 per unit of production
for kiln i, kilograms (pounds) of Cl2 per megagram (ton)
of fired product
RfCHCl = reference concentration for HCl, 20 micrograms
per cubic meter
RfCHF = reference concentration for HF, 14 micrograms per
cubic meter
RfCCl2 = reference concentration for Cl2, 0.15
micrograms per cubic meter

    (ii) If you have multiple tunnel kilns at your facility, sum the
maximum potential HCl-equivalent values for all tunnel kilns at the
facility using Equation 5:
[GRAPHIC] [TIFF OMITTED] TR26OC15.018

Where:

Emax total = maximum potential HCl-equivalent emissions
for total of all kilns at facility, kilograms (pounds) per hour
Emax i = maximum potential HCl-equivalent emissions for
kiln i, kilograms (pounds) per hour
n = number of tunnel kilns at facility

    (iii) If you have a single tunnel 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, determine the maximum process rate for the
tunnel kiln using Equation 6 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.
[GRAPHIC] [TIFF OMITTED] TR26OC15.019

Where:

Pmax i = maximum process rate for kiln i, megagrams
(tons) per hour
HCl-eq = HCl-equivalent limit in Table 1 to this subpart, 26
kilograms (57 pounds) per hour
MPiHCl = mass of HCl per unit of production for kiln i,
kilograms (pounds) of HCl per megagram (ton) of fired product
MPiHF = mass of HF per unit of production for kiln i,
kilograms (pounds) of HF per megagram (ton) of fired product
MPiCl2 = mass of Cl2 per unit of production
for kiln i, kilograms (pounds) of Cl2 per megagram (ton)
of fired product

micrograms per cubic meter

    (iv) If you have multiple tunnel kilns 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, 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.

subpart including, but not limited to, any emission limitation
(including any operating limit) or work practice standard; or
    (2) Fails to meet any term or condition that is adopted to
implement an applicable requirement in this subpart for any affected
source required to obtain such a permit.
    Dry lime injection fabric filter (DIFF) means an APCD that includes
continuous injection of hydrated lime or other sorbent into a duct or
reaction chamber followed by a fabric filter.
    Dry lime scrubber/fabric filter (DLS/FF) means an APCD that
includes

continuous injection of humidified hydrated lime or other sorbent into
a reaction chamber followed by a fabric filter. These systems typically
include recirculation of some of the sorbent.
    Dry limestone adsorber (DLA) means an APCD that includes a
limestone storage bin, a reaction chamber that is essentially a packed
tower filled with limestone, and may or may not include a peeling drum
that mechanically scrapes reacted limestone to regenerate the stone for
reuse.
    Emission limitation means any emission limit or operating limit.
    Fabric filter means an APCD used to capture PM by filtering a gas
stream through filter media; also known as a baghouse.
    Initial startup means:
    (1) For a new or reconstructed tunnel kiln controlled with a DLA,
the time at which the temperature in the kiln first reaches 260 [deg]C
(500 [deg]F) and the kiln contains product; or
    (2) for a new or reconstructed tunnel kiln controlled with a DIFF,
DLS/FF, or wet scrubber (WS), the time at which the kiln first reaches
a level of production that is equal to 75 percent of the kiln design
capacity or 12 months after the affected source begins firing BSCP,
whichever is earlier.
    Fired product means brick or structural clay products that have
gone through the firing process via kilns.
    Kiln exhaust process stream means the portion of the exhaust from a
tunnel kiln that exhausts directly to the atmosphere (or to an APCD),
rather than to a sawdust dryer.
    Large tunnel kiln means a tunnel kiln (existing, new, or
reconstructed) with a design capacity equal to or greater than 9.07 Mg/
hr (10 tph) of fired product.
    Minimum APCD inlet temperature means the minimum temperature that
kiln exhaust can be vented to the APCD that ensures the long-term
integrity of the APCD.
    Particulate matter (PM) means, for purposes of this subpart,
emissions of PM that serve as a measure of total particulate emissions,
as measured by Method 5 (40 CFR part 60, appendix A-3) or Method 29 (40
CFR part 60, appendix A-8), and as a surrogate for non-mercury metal
HAP contained in the particulates including, but not limited to,
antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead,
manganese, nickel, and selenium.
    Periodic kiln means a batch firing kiln.
    Plant site means all contiguous or adjoining property that is under
common control, including properties that are separated only by a road
or other public right-of-way. Common control includes properties that
are owned, leased, or operated by the same entity, parent entity,
subsidiary, or any combination thereof.
    Responsible official means responsible official as defined in 40
CFR 70.2.
    Small tunnel kiln means a tunnel kiln (existing, new, or
reconstructed) with a design capacity less than 9.07 Mg/hr (10 tph) of
fired product.
    Startup means the setting in operation of an affected source and
starting the production process.
    Startup push rate means the kiln push rate required to bring the
kiln to the proper operating temperature during startup.
    Tunnel kiln means any continuous kiln that is used to fire BSCP.
Some tunnel kilns have two process streams, including a process stream
that exhausts directly to the atmosphere or to an APCD, and a process
stream in which the kiln exhaust is ducted to a sawdust dryer where it
is used to dry sawdust before being emitted to the atmosphere.
    Tunnel kiln design capacity means the maximum amount of brick, in
Mg (tons), that a kiln is designed to produce in one year divided by
the number of hours in a year (8,760 hours), taking into account the
void space in the brick, the push rate for the kiln, and the stacking
pattern, if applicable. If a kiln is modified to increase the capacity,
the design capacity is considered to be the capacity following
modifications.
    Wet scrubber (WS) means an APCD that uses water, which may include
caustic additives or other chemicals, as the sorbent. Wet scrubbers may
use any of various design mechanisms to increase the contact between
exhaust gases and the sorbent.
    Work practice standard means any design, equipment, work practice,
operational standard, or combination thereof, that is promulgated
pursuant to section 112(h) of the Clean Air Act.
