What This Subpart Covers

§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 
Page 3 of 105

continuous compliance with the emission limitations and work 

practice standards.

§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 

40 CFR 63.9824, or brick and structural clay products (BSCP), as 

defined in 40 CFR 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.

(including operating limits) in this subpart at all times, 

except during periods of 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.
Page 9 of 105

(b) Except as specified in paragraph (d) of this section(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 §63.8545 

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 source that is subject to the 

emission limits specified in Table 1 to this subpart, you must 

prepare and implement a written operation, maintenance, and 
Page 10 of 105

monitoring (OM&M) plan according to the requirements in 

§63.8575.

(d) If you own or operate an affected source 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 affected source, you may bypass the source 

control device and continue operating the affected source 

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 ato use the routine control device 

maintenance exemptionalternative standard from the Administrator

no later than 120 calendar days before the compliance date 

specified in §63.8545. 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 source shutdowns, describe how you plan to minimize 

emissions to the greatest extent possibleprovide 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 
Page 11 of 105

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 exemption must 

not exceed 4 percent of the annual operating uptime for each 

affected source.

(3) The request for the routine control device maintenance 

exemptionalternative standard, if approved by the Administrator,

Continuous Compliance Requirements

§63.8615 How do I monitor and collect data to demonstrate 

continuous compliance?

(a) You must monitor and collect data according to this 

section.
Page 31 of 105

(b) Except for periods of monitor malfunctions, associated 

repairs, and required quality assurance or control activities 

(including, as applicable, calibration checks and required zero 

and span adjustments), you must monitor continuously (or collect 

data at all required intervals) at all times that the affected 

source is operating. This includes periods of startup, shutdown, 

malfunction, and routine control device maintenance as specified 

in §63.8570(d) when the affected source is operating.

(c) You may not use data recorded during monitoring 

malfunctions, associated repairs, out-of-control periods, or 

required quality assurance or control activities for purposes of 

calculating data averages. A monitoring malfunction is any 

sudden, infrequent, not reasonably preventable failure of the 

monitoring system to provide valid data. Monitoring failures 

that are caused in part by poor maintenance or careless 

operation are not malfunctions. You must use all the valid data 

collected during all other periods in assessing compliance. Any 

averaging period for which you do not have valid monitoring data 

and such data are required constitutes a deviation from the 

monitoring requirements.

§63.8620 How do I demonstrate continuous compliance with the 

emission limitations and work practice standards?

(a) You must demonstrate continuous compliance with each 

emission limit, operating limit, and work practice standard in

demonstrate continuous compliance with each emission limit in 

Table 1 to this subpart, and each operating limit established as 

required in §63.8595(h)(2) according to the methods specified in 

your approved alternative monitoring procedures request, as 

described in §§63.8595(h)(1) and 63.8(f).

(c) You must report each instance in which you did not meet 

each emission limit and operating limit in this subpart that 

applies to you. This includes periods of startup, shutdown, 

malfunction, and routine control device maintenance. These 

instances are deviations from the emission limitations in this 

subpart. These deviations must be reported according to the 

requirements in §63.8635.(c)(8).

(d) Deviations that occur during periods of control device 

maintenance covered by an approved routine control device 

maintenance exemption according to §63.8570(d) are not 

violations if you demonstrate to the Administrator's 
Page 33 of 105

satisfaction that you were operating in accordance with the 

approved routine control device maintenance exemption.

(d) [Reserved]

(e) 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) through (3) of this section.

(1) Perform daily VE observations of each kiln stack 

according to the procedures of Method 22 of 40 CFR part 60, 

appendix A-7. You must conduct the Method 22 test while the

duration of each Method 22 test must be at least 15 minutes.

(2) If VE are observed during any daily test conducted 

using Method 22 of 40 CFR part 60, appendix A-7, you must 

promptly initiate and complete corrective actions according to 

your OM&M plan. If no VE are observed in 30 consecutive daily 

Method 22 tests for any kiln stack, you may decrease the 

frequency of Method 22 testing from daily to weekly for that 

kiln stack. If VE are observed during any weekly test, you must 

promptly initiate and complete corrective actions according to 

your OM&M plan, resume Method 22 testing of that kiln stack on a 

daily basis, and maintain that schedule until no VE are observed 
Page 34 of 105

in 30 consecutive daily tests, at which time you may again 

decrease the frequency of Method 22 testing to a weekly basis.

(3) 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 §63.8635.
