3. What Are the Emission Limits, Operating Limits, and Other Standards?
 The
final rule contains five subcategories: General use coating,
high performance coating, magnet wirecoating, rubber-to-metal
coating, and extreme performance fluoropolymer coating. The
general use subcategory includes all surface coating operations
in the miscellaneous metal parts and products source category
that are not included in the other four subcategories. This
includes operations that coat a wide variety of substrates,
surfaces, and types of miscellaneous metal parts and products.
It also includes asphalt/coal tar application to metal pipes.
High performance coating is any coating that meets the definition
of ‘‘high performance architectural coating’’ or ‘‘high
temperature coating.’’ Specific definitions can
be found in the final rule.

Emission Limits. The US EPA
is limiting organic HAP emissions from each existing
affected source using the emission limits in Table 2. For
each new or reconstructed affected source, the final emission
limits are given in Table 3. For each of the subcategories,
the emission limit is expressed as the mass of organic
HAP emissions per volume of coating solids (or density)
used during each 12-month compliance period.

Operating Limits
 If the source reduces emissions by using a capture system
and add-on control device (other than a solvent recovery
system for which they conduct a liquid-liquid material
balance), the operating limits applies. These limits
are site-specific parameter limits that the source determines
during the initial performance test of the system.
Work Practice Standards
If a facility uses an emission capture system and control
device for compliance, they must develop and implement
a work practice plan to minimize organic HAP emissions
from mixing operations; storage tanks and other containers;
and handling operations for coatings, thinners and/or
other additives, cleaning materials, and waste materials.
Startup, Shutdown, and Malfunction Plan
If a facility use a capture system and control device for
compliance, you are required to develop and operate according
to a startup, shutdown, and malfunction plan (SSMP) during
periods of startup, shutdown, or malfunction of the capture
system and control device.
