Other Requirements and Information

Sec.  63.11510  What General Provisions apply to this subpart?

    If you own or operate a new or existing affected source, you must

comply with the requirements of the General Provisions (40 CFR part 63,
subpart A) according to Table 1 of this subpart.

Sec.  63.11511  What definitions apply to this subpart?

    Terms used in this subpart are defined in this section.
    Batch electrolytic process tank means a tank used for an
electrolytic process in which a part or group of parts, typically
mounted on racks or placed in barrels, is placed in the tank and
immersed in an electrolytic process solution as a single unit (i.e., as
a batch) for a predetermined period of time, during which none of the
parts are removed from the tank and no other parts are added to the
tank, and after which the part or parts are removed from the tank as a
unit.
    Bath means the liquid contents of a tank that is used for
electroplating, electroforming, electropolishing, or other metal
coating processes at a plating and polishing facility.
    Capture system means the collection of components used to capture
gases and fumes released from one or more emissions points and then
convey the captured gas stream to a control device, as part of a
complete control system. A capture system may include, but is not
limited to, the following components as applicable to a given capture
system design: duct intake devices, hoods, enclosures, ductwork,
dampers, manifolds, plenums, and fans.
    Cartridge filter means a type of control device that uses
perforated metal cartridges containing a pleated paper or non-woven
fibrous filter media to remove PM from a gas stream by sieving and
other mechanisms. Cartridge filters can be designed with single use
cartridges, which are removed and disposed after reaching capacity, or
continuous use cartridges, which typically are cleaned by means of a
pulse-jet mechanism.
    Composite mesh pad means a type of control device similar to a mesh
pad mist eliminator except that the device is designed with multiple
pads in series that are woven with layers of material with varying
fiber diameters, which produce a coalescing effect on the droplets or
PM that impinge upon the pads.
    Continuous electrolytic process tank means a tank that uses an
electrolytic process and in which a continuous metal strip or other
type of continuous substrate is fed into and removed from the tank
continuously. This process is also called reel-to-reel electrolytic
plating.
    Control device means equipment that is part of a control system
that collects and/or reduces the quantity of a pollutant that is
emitted to the air. The control device receives emissions that are
transported from the process by the capture system.
    Control system means the combination of a capture system and a
control device. The capture system is designed to collect and transport
air emissions from the affected source to the control device. The
overall control efficiency of any control system is a combination of
the ability of the system to capture the air emissions (i.e., the
capture efficiency) and the control device efficiency. Consequently, it
is important to achieve good capture to ensure good overall control
efficiency. Capture devices that are known to provide high capture
efficiencies include hoods, enclosures, or any other duct intake
devices with ductwork, dampers, manifolds, plenums, or fans.
    Cyanide plating means plating processes performed in tanks that use
cyanide as a major bath ingredient and that operate at pH of 12 or
more, and use or emit any of the plating and polishing metal HAP, as
defined in this section. Electroplating and electroforming are
performed with or without cyanide. The cyanide in the bath works to
dissolve the HAP metal added as a cyanide compound (e.g., cadmium
cyanide) and creates free cyanide in solution, which helps to corrode
the anode. These tanks are self-regulating to a pH of 12 due to the
caustic nature of the cyanide bath chemistry. The cyanide in the bath
is a major bath constituent and not an additive; however, the self-
regulating chemistry of the bath causes the bath to act as if wetting
agents/fume suppressants are being used and to ensure an optimum
plating process. All cyanide plating baths at pH greater than or equal
to 12 have cyanide-metal complexes in solution. The metal HAP to be
plated is not emitted because it is either bound in the metal-cyanide
complex or reduced at the cathode to elemental metal, and plated onto
the immersed parts. Cyanide baths are not intentionally operated at pH
less 12 since unfavorable plating conditions would occur in the tank,
among other negative effects.
    Deviation means any instance in which an affected source or an
owner or operator of such an affected source:
    (1) Fails to meet any requirement or obligation established by this
rule including, but not limited to, any equipment standard (including
emissions and operating limits), management practice, or operation and
maintenance requirement;
    (2) Fails to meet any term or condition that is adopted to
implement an applicable requirement in this rule and that is included
in the operating permit for any affected facility required to obtain
such a permit; or
    (3) Fails to meet any equipment standard (including emission and
operating limits), management standard, or operation and maintenance
requirement in this rule during startup, shutdown, or malfunction.
    Dry mechanical polishing means a process used for removing defects
from and smoothing the surface of finished metals and formed products
after plating with any of the plating and polishing metal HAP, as
defined in this section, using hard-faced abrasive wheels or belts and
where no liquids or fluids are used to trap the removed metal
particles.
    Electroforming means an electrolytic process using or emitting any
of the plating and polishing metal HAP, as defined in this section,
that is used for fabricating metal parts. This process is essentially
the same as electroplating except that the plated substrate (mandrel)
is removed, leaving only the metal plate. In electroforming, the metal
plate is self-supporting and generally thicker than in electroplating.
    Electroless plating means a non-electrolytic process that uses or
emits any of the plating and polishing metal HAP, as defined in this
section, in which metallic ions in a plating bath or solution are
reduced to form a metal coating at the surface of a catalytic substrate
without the use of external electrical energy. Electroless plating is
also called non-electrolytic plating. Examples include, but are not
limited to, chromate conversion coating, nickel acetate sealing, sodium
dichromate sealing, and manganese phosphate coating.
    Electrolytic plating processes means electroplating and
electroforming that use or emit any of the plating and polishing metal
HAP, as defined in this section, where metallic ions in a plating bath
or solution are reduced to form a metal coating on the surface of parts
and products using electrical energy.
    Electroplating means an electrolytic process that uses or emits any
of the plating and polishing metal HAP, as defined in this section, in
which metal ions in solution are reduced onto the surface of the work
piece (the cathode) via an electrical current. The metal ions in the
solution are usually replenished by the dissolution of metal from solid
metal anodes fabricated of the same metal being plated, or by direct

replenishment of the solution with metal salts or oxides;
electroplating is also called electrolytic plating.
    Electropolishing means an electrolytic process that uses or emits
any of the plating and polishing metal HAP, as defined in this section,
in which a work piece is attached to an anode immersed in a bath, and
the metal substrate is dissolved electrolytically, thereby removing the
surface contaminant; electropolishing is also called electrolytic
polishing.
    Fabric filter means a type of control device used for collecting PM
by filtering a process exhaust stream through a filter or filter media.
A fabric filter is also known as a baghouse.
    Flash electroplating means an electrolytic process that uses or
emits any of the plating and polishing metal HAP, as defined in this
section, and that is used no more than 3 cumulative minutes per hour or
no more than 1 cumulative hour per day.
    General Provisions of this part (40 CFR part 63, subpart A) means
the section of the Code of Federal Regulations (CFR) that addresses air
pollution rules that apply to all HAP sources addressed in part 63,

chemicals and compounds specified in the CAA Amendments of 1990; HAP
are also called ``air toxics.'' The five plating and polishing metal
HAP, as defined in this section, are on this list of 188 chemicals.
    High efficiency particulate air (HEPA) filter means a type of
control device that uses a filter composed of a mat of randomly
arranged fibers and is designed to remove at least 99.97 percent of
airborne particles that are 0.3 micrometers or larger in diameter.
    Mesh pad mist eliminator means a type of control device, consisting
of layers of interlocked filaments densely packed between two
supporting grids that remove liquid droplets and PM from the gas stream
through inertial impaction and direct interception.
    Metal coating operation means any process performed either in a
tank that contains liquids or as part of a spraying operation that
applies one or more plating and polishing metal HAP, as defined in this
section, to parts and products used in manufacturing. These processes
include but are not limited to: Non-chromium electroplating;
electroforming; electropolishing; other non-electrolytic metal coating
processes, such as chromate conversion coating, nickel acetate sealing,
sodium dichromate sealing, and manganese phosphate coating; and thermal
spraying.
    New source means any affected source for which you commenced
construction or reconstruction after March 14, 2008.
    Non-cyanide electrolytic plating and electropolishing processes
means electroplating, electroforming, and electropolishing that uses or
emits any of the plating and polishing metal HAP, as defined in this
section, performed without cyanide in the tank. These processes do not
use cyanide in the tank and operate at pH values less than 12. These
processes use electricity and add or remove metals such as metal HAP
from parts and products used in manufacturing. Both electroplating and
electroforming can be performed with cyanide as well.
    Non-electrolytic plating means a process that uses or emits any of
the plating and polishing metal HAP, as defined in this section, in

of external electrical energy. Non-electrolytic plating is also called
electroless plating. Examples include chromate conversion coating,
nickel acetate sealing, sodium dichromate sealing, and manganese
phosphate coating.
    Packed-bed scrubber means a type of control device that includes a
single or double packed bed that contains packing media on which PM and
droplets impinge and are removed from the gas stream. The packed-bed
section of the scrubber is followed by a mist eliminator to remove any
water entrained from the packed-bed section.
    Plating and polishing facility means a facility engaged in one or
more of the following processes that uses or emits any of the plating
and polishing metal HAP, as defined in this section: Electroplating
processes other than chromium electroplating (i.e., non-chromium
electroplating); electroless plating; other non-electrolytic metal
coating processes, such as chromate conversion coating, nickel acetate
sealing, sodium dichromate sealing, and manganese phosphate coating;
thermal spraying; and the dry mechanical polishing of finished metals
and formed products after plating.
    Plating and polishing metal HAP means any compound of any of the
following metals: cadmium, chromium, lead, manganese, and nickel, or
any of these metals in the elemental form, with the exception of lead.
Any material that does not contain cadmium, chromium, lead, or nickel
in amounts greater than or equal to 0.1 percent by weight, and does not
contain manganese in amounts greater than or equal to 1.0 percent by
weight, as reported on the Material Safety Data Sheet for the material,
is not considered to be a plating and polishing metal HAP.
    Plating and polishing process tanks means any tank in which a

electroplating) performed in a tank; electroless plating; and non-
electrolytic metal coating processes, such as chromate conversion
coating, nickel acetate sealing, sodium dichromate sealing, and
manganese phosphate coating; and electropolishing. This term does not
include tanks containing solutions that are used to rinse or wash parts
prior to placing the parts in a plating and polishing process tank, or

designed to cover at least 75 percent of the open surface of the tank
or process unit that is used for continuous plating or other continuous
metal coating processes.
    Temporary thermal spraying means a thermal spraying operation that
uses or emits any of the plating and polishing metal HAP, as defined in
this section, and that lasts no more than 1 hour in duration during any
one day and is conducted in situ. Thermal spraying that is conducted in
a dedicated thermal

spray booth or structure is not considered to be temporary thermal
spraying.
