**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 subje ct 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

crit eria 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 f acilities 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 product s , 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 stationar y 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.

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

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.

paragraph upon approval by the Administrator and provided you satisfy the conditions listed in paragraphs (d)(1) through (5)

of this section.

maintenance activities and the frequency of the maintenance
activities, explain why the mainte nance cannot be accomplished
during source shutdowns, describe how you plan to minimize
emissions to the greatest extent possible 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

section.

### Page 31 of 105

(b) Except for periods of monitor malfunctions, associated
