Amendments to National Emission Standards for Hazardous Air
Pollutants for Area Sources: Plating and Polishing
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule; amendments.
-----------------------------------------------------------------------
SUMMARY: On June 12, 2008, EPA issued national emission standards for
control of hazardous air pollutants (HAP) for the plating and polishing
area source category under section 112 of the Clean Air Act (CAA). In
today's action, EPA is taking direct final action to amend the national
emission standards for HAP (NESHAP) for the plating and polishing area
source category. These final amendments clarify that the emission
control requirements of the plating and polishing area source NESHAP do
not apply to any bench-scale activities. Also, several technical
corrections and clarifications that do not make significant changes in
the rule's requirements have been made to the rule text. We are making
these amendments by direct final rule, without prior proposal, because
we view these revisions as noncontroversial and anticipate no adverse
comments. Consistent with Executive Order 13563, ``Improving Regulation
and Regulatory Review,'' issued on January 18, 2011, this amended rule
will increase flexibility and freedom of choice for the public, and
make the rule more clear and intelligible which, as a result, will
reduce the burden.
DATES: This final rule is effective on September 19, 2011 without
further notice, unless EPA receives significant adverse comment by July
20, 2011. If the effective date is delayed, timely notice will be
published in the Federal Register. If EPA receives adverse comment, we
will publish a timely withdrawal in the Federal Register informing the
public that some or all of the amendments in this rule will not take
effect.

I. Why is EPA using a direct final rule?
EPA is publishing this final rule without a prior proposed rule
because we view this as a noncontroversial action and anticipate no
significant adverse comment. These amendments to the national emission
standards for hazardous air pollutants (NESHAP) for plating and
polishing operations that are area sources (40 CFR part 63, subpart
WWWWWW) consist of a clarification stating that the emission control
requirements of the plating and polishing area source rule do not apply
to bench-scale activities, and technical corrections and clarifications
that do not make material changes to the rule's requirements. However,
in the ``Proposed Rules'' section of this Federal Register, we are
publishing a separate document that will serve as the proposed rule to
amend the area source standards if EPA receives significant adverse
comments on this final rule. We will not institute a second comment
period on this action. Any parties interested in commenting must do so
at this time. For further information about commenting on the rule, see
the ADDRESSES section of this document. If we receive significant
adverse comments, we will withdraw only those provisions on which we
received significant adverse comments. We will publish a timely
withdrawal in the Federal Register indicating which provisions will
become effective and which provisions are being withdrawn.

V. Why are we amending this rule?
On July 1, 2008 (73 FR 37741), we issued the NESHAP for Area
Sources: Plating and Polishing (40 CFR part 63, subpart WWWWWW). The
final rule establishes air emission control requirements for new and
existing facilities that are area sources of hazardous air pollutants.
The final standards establish emission standards in the form of
management practices for new and existing tanks, thermal spraying
equipment, and dry mechanical polishing equipment in certain plating
and polishing processes. These final emission standards reflect EPA's
determination regarding the generally achievable control technology
(GACT) and/or management practices for the area source category.
In the time period since promulgation, it has come to our attention
that certain aspects of the rule as promulgated have led to
misinterpretations, inconsistencies, and confusion regarding the
applicability of the rule. These amendments make several technical
corrections and clarifications to the rule's text that should reduce
misinterpretations. Therefore, we are amending and correcting parts of
the rule to address these issues.
In addition to fulfilling the mandate in CAA section 112, these
amendments are also responsive to Executive Order 13563, ``Improving
Regulation and Regulatory Review,'' issued on January 18, 2011, which
directs each Federal agency to ``periodically review its existing
significant regulations to determine whether any such regulations
should be modified, streamlined, expanded, or repealed so as to make
the agency's regulatory program more effective or less burdensome in
achieving the regulatory objectives.'' EPA's amended rule will increase
flexibility and freedom of choice for the public, and make the rule
more clear and intelligible which, as a result, will reduce the burden.
VI. What are the changes to the area source NESHAP for plating and
polishing operations?
We are amending this rule to clarify and correct inconsistencies
and inadequacies of the rule language that have come to our attention
since promulgation. These items are discussed in this section. There is
also a red-line version of the regulatory text in the docket that shows
the effect of these changes on the promulgated rule.
A. Clarification of Applicability for Bench-Scale Operations
EPA is making these amendments to the NESHAP for plating and
polishing operations that are area sources (40 CFR part 63, subpart
WWWWWW) to clarify that the rule was not intended to apply to process
units that are bench-scale operations.
Based on available inventory information, we believe that HAP
emissions from bench-scale activities were not part of the 1990
baseline inventory that supported the area source listing decision for
this category. The plating and polishing category includes job shop
operations dedicated to plating and polishing operations, and original
equipment manufacturers with large-scale plating and polishing
processes. We believe that this definition is also consistent with the
basis of the listing of the plating and polishing source category in
the 1990 air toxics inventory. Therefore, this proposed amendment
clarifies that the emission control requirements of the plating and
polishing area source rule do not apply to bench-scale activities.
Further, our experience is that the types of plating and polishing
operations that are bench scale use small containers on the scale of 25
gallons or less, and any potential air emissions would be too low to
measure. Bench-scale processes are defined in this final rule as: ``Any
operation that is small enough to be performed on a bench, table, or
similar structure so that the equipment is not directly contacting the
floor.''
B. Other Technical Corrections and Clarifications
To clarify our intent in the rule and reduce misinterpretations
that have come to our attention since the final rule was published in
July 2008, we have made certain clarifications and technical
corrections to the rule text.
We are clarifying that certain process units and operations are not
part of the affected activity, based on our knowledge of the area
source inventory on which the source category description was derived.
These processes include activities such as plating, polishing, coating
or thermal spraying conducted to repair surfaces or equipment.
Similarly, other EPA area source rules also do not include repair and
maintenance activities at manufacturing facilities as affected
operations for air pollution control purposes, such as area source
regulations for Nine Metal Fabrication and Finishing source categories
(40 CFR part 63, subpart XXXXXX).
In addition, we are clarifying the descriptions of standards and
management practices to better reflect the industry and manufacturer's
equipment operations. For example, in the standards and compliance
requirements, the addition of wetting agents/fume suppressants to tank
baths has been clarified to reflect
[[Page 35747]]
manufacturers' specifications, including flexibility to the operator
that may be provided in the specifications. We intended the
requirements of the final rule to be consistent with practices
conducted based on manufacturers' specifications. Definitions of
operations and procedures were also corrected in order to clarify the
scope of the rule, the affected processes, and make applicability and
other definitions consistent within the rule. These are listed in the
following paragraphs.
We are clarifying that certain operations were not part of the
original urban air toxics inventory on which this source category was
defined and, therefore, we are revising the regulatory text to clarify
that these operations are not subject to the requirements of the rule,
as described below.
We are clarifying that the affected operations do not include
plating or polishing performed to repair equipment or for maintenance
purposes. The final rule excluded repair operations performed with
thermal spraying as a result of comments received after proposal. In
the time period since the rule was promulgated, we learned that plating
or coating was also done for repair purposes, usually with small paint
brushes and not in tanks. Therefore, we have amended the rule to add
``any'' plating and polishing process as the types of repair processes
which are not affected operations under the rule. This change is based
on the original urban air toxics inventory on which the source category
was defined.
We are clarifying that certain operations were intended to be part
of the affected sources and, therefore, we are revising the regulatory
text to clarify that these operations are subject to the requirements
of the rule, as described below.
We are clarifying that thermal spraying is another process to which
the requirements for dry mechanical polishing apply. The final rule
stated that dry mechanical polishing was an affected process if
performed after plating. Since thermal spraying is one of the plating
and polishing processes used to plate metal onto surfaces, we intended
to include dry mechanical polishing done after thermal spraying as an
affected process, and are making that clarification in today's action.
We are also clarifying that language of the rule to reflect the
fact that flame spraying, which is a different name for thermal
spraying, is subject to the rule. We are also clarifying that thermal
and flame spraying do not include spray painting at ambient
temperatures. After promulgation of the final rule, we learned that
flame spraying is another name for thermal spraying--both terms are
used for an identical process. However, spray coating at room
temperatures is another process entirely, with a different definition,
and is already addressed under subpart HHHHHH of this part, which
regulates spray painting and other similar spray coating processes
performed without the use of heat or flame. Therefore, spray coating at
room temperatures is not subject to the requirements of this rule.
In addition, we are making clarifications to the rule language to
better describe certain rule requirements which have been
misinterpreted since the time of promulgation. The following is a
discussion of these items.
First, we are clarifying that although Material Safety Data Sheets
(MSDS) may be used to determine the amount of plating and polishing
metal HAP in materials used in the plating or polishing process, MSDS
are not required to be used and are not the only method to determine
HAP content. Other methods include laboratory analysis or engineering
estimate of the HAP content of the bath, which are also reliable
indicators of HAP content. The reference to MSDS in the final rule was
only intended to provide an example of readily available resources to
determine the HAP content of materials used in plating and polishing
and was not meant to be the exclusive method to be used. Other methods
of analysis are available, such as laboratory testing, which provide
equal and often better information than the MSDS. Therefore, we are
amending the rule to allow these other methods.
We are also clarifying that for plating or polishing tanks, the HAP
content may be determined from the final bath contents ``as used'' to
plate or to polish rather than the HAP content of the individual
components, to better reflect the fact that HAP emissions are based on
the concentration of HAP within the tank. The most important
concentration of plating HAP as it relates to the potential for HAP to
be emitted is the concentration of HAP within the tank. We received
information after promulgation of the final rule demonstrating that
measuring the concentration of pure ingredients in the pure form (``as
added'') could misrepresent the HAP concentration within the tank for
some platers. Therefore, in today's action we are amending the rule to
also allow measurement of HAP content of the final solution within the
tank to determine applicability to the rule. We are retaining the ``as
added'' measurement point since this point provides a conservative
value because the materials added will only be more dilute once they
are placed in the tank, and because it may be easier to perform the
measurement ``as added'' for some plating operations. Facilities may
still use the HAP concentrations specified in the individual MSDS for
each ingredient used in the tank to establish the total HAP content of
the tank for the purposes of this rule.
We are clarifying that when facilities add wetting agent/fume
suppressant to replenish the plating baths, they can add these
ingredients in amounts such that the bath contents are returned to that
of the original make-up of the bath and do not have to add the full
amounts originally added on startup. Adding more wetting agent/fume
suppressant than needed to return the bath contents to their original
make-up will not necessarily reduce HAP emissions. This revision
ensures that the concentration of the wetting agent/fume suppressant
does not change. The wetting agent/fume suppressant concentration in
the tank is one of the key features for proper plating as well as for
emission control. However, adding more wetting agent/fume suppressant
beyond the amount recommended by the manufacturer is not necessarily
better for pollution control and in many cases could be detrimental to
the plating process itself. Therefore, we are permitting the addition
of smaller amounts of wetting agent than that original amount as long
as the amount added brings the tank back to its original concentration
of wetting agent/fume suppressant. We intended in the final rule that
platers maintain the concentration of wetting agent/fume suppressant as
recommended by the manufacturer and this change today enables platers
to add only the amount that is needed to maintain the correct
concentration.
We are also clarifying the definition of startup of an affected
plating or polishing bath to explain that startup of the bath does not
include events where only the tank's heating or agitation and other
mechanical operations are turned back on after being turned off for a
period of time. The chemical make-up of the original tank bath is the
key point in time at which startup of the tanks occurs, rather than the
existence of electricity supplied to the tanks for heating, agitation,
or other physical conditions. Therefore, we are revising the definition
of the startup of tanks to specify that this time is when the tank
baths are originally created. If startup begins at the time electricity
is delivered to the tank, this could lead to facilities refraining from
turning off the power when the tanks are not in use to avoid startup
requirements when the plating is
[[Page 35748]]
resumed. This practice could lead to wasting of energy and possibly
increases in air pollution as tanks remain heated or agitated for hours
longer than needed. Therefore, by defining tank startup as the time of
the original bath make-up, we are encouraging facilities to shut down
the electricity to their tanks when not in use and eliminating
unnecessary startup procedures to comply with the rule.
We are also adding ``cartridge'' filters as a type of filter that
can fulfill the control requirement in all instances where the general
category of ``filters'' are specified. Cartridge filters are a specific
type of filter used in air pollution control that give the same
performance as fabric filters in terms of particle control in, for
example, dry mechanical polishing or thermal spraying. Cartridge
filters are more compact than fabric filters and more useful in
industrial machinery settings where space is limited. Therefore, we
have added cartridge filters as a type of filter permitted as a control
device under the rule.
We are also clarifying that the rule requirement to maintain and
record the minimum amount of time that tank covers must be used is only
applicable when covers are the sole method of complying with the GACT
operating standards, and these requirements for recordkeeping do not
apply when another method is used to comply with the GACT operating
standards, or when covers are used as a management practice. The use of
covers is a method of complying with the GACT operating standards for
electroplating processes as well for complying with the management
practices for both electrolytic and electroless plating, and polishing
operations. When covers are used as a management practice, there are no
specific requirements under the rule for the amount of time or the
amount of surface area coverage as there is for the GACT operating
standards. Covers used for complying with the GACT operating standard
are more critical to emission control and therefore need to have
stricter time requirements, such as 95 percent of the plating time or,
in the case of continuous plating, cover 75 percent of the surface
area. Covers used as a management practice are used on processes where
either control of emissions is not critical to pollution control due to
low emissions, or where other methods of control are being used to meet
the GACT requirements, such as wetting agents/fume suppressant. In many
cases, covers are used as a management practice where the process does
not allow the covers to be used for as much time or over as much
surface area as the operating standards in the rule. Factors that can
interfere in the use of covers for as long as needed to meet the GACT
operating standard are, for example, processes where workers have to
remove and load parts frequently. In this situation, another method of
achieving the operating standard is used, such as wetting agents/fume
suppressant. The use of covers for any part of the plating time,
regardless of other controls or practices employed, is a management
strategy for pollution prevention and should be encouraged.
Therefore, we are clarifying that when covers are used as a
management practice, facilities are not required to document the time
the covers are in place in the same way as covers used for meeting the
GACT operating standard. We are amending the rule today to make this
point clear and to encourage pollution prevention achieved by the use
of covers, in general.
We are also clarifying that limiting and recording the time of
plating to fulfill the flash or short-term requirements in the rule is
only applicable when facilities comply with the GACT standard of this
subpart solely by limiting the plating time of the affected tank, and
do not apply to plating done for short periods of time in general,
where other methods are used to comply with the GACT standards. Tanks
that perform plating for short periods of time, in general, are not
required to use the GACT regulatory option of limiting and recording
plating time to comply with the rule if another method of compliance is
used.
Similar to the discussion above on the use of covers, if facilities
with short-term plating use another method to comply with the rule, we
encourage them to still keep their plating times short and, hence,
minimize potential pollution. Therefore, we are clarifying that
documentation is not required for the practice of short-term plating,
in general, when another method of compliance with the rule is used.
We are clarifying that if a new affected source is started after
July 1, 2008, an Initial Notification must be submitted upon startup.
The final rule erroneously required the Initial Notification for new
sources to be submitted after 120 days of startup of the process (Sec.
63.11509(a)(3) ``What are my notification, reporting, and recordkeeping
requirements?'') as a result of a typographical error. Since we
generally require initial notification for new sources upon startup, we
have corrected the submittal date of the initial notification.
We are clarifying that if a facility makes a change to the methods
of compliance with the standard, an amended Notification of Compliance
Status should be submitted within 30 days of the change. Note that this
does not apply to any changes in the listed management practices. This
requirement is intended to ensure that EPA is aware of changes in the
process or controls that may affect HAP emissions and compliance with
the rule. This notification can be in the form of the annual report
already required under the rule. This additional step includes the
small task of mailing beyond the already required preparation of the
annual report, and should not occur for many facilities in the industry
and also not frequently. Therefore we estimate that the burden of this
additional requirement is negligible. Electronic notifications may be
allowable by the air permit authorities or EPA regional representative
in some states or regions.
We are also clarifying that the management practices apply to all
affected plating and polishing operations, as practicable, not just
affected plating tanks. In the final rule, the management practices
were intended to apply to all plating and polishing operations under
this subpart and this amendment corrects that applicability. The word
``plating'' as used in the promulgated rule was intended to be a short
phrase to represent all plating and polishing operations. Although most
of the management practices do apply to tanks, there are others that
apply to all plating and polishing sources, such as: ``general good
housekeeping,'' such as regular sweeping or vacuuming, if needed;
``periodic washdowns,'' as practicable; and ``regular inspections'' to
identify leaks and other opportunities for pollution prevention.
Therefore, we are clarifying that management practices apply to all
plating and polishing operations.
We have also made corrections that were primarily typographical in
nature, and added definitions for terms used in the rule that were not
defined or needed to be clarified to clarify our original intent in the
rule. The revised or added definitions to the rule are as follows (in
alphabetical order): ``bath,'' ``bench-scale plating or polishing,''
``conversion coatings,'' ``dry mechanical polishing,''
``electropolishing,'' ``fabric filter,'' ``flash electroplating,''
``maintenance,'' ``major facility,'' ``metal coating operation,''
``metal HAP content,'' ``non-electrolytic plating,'' ``plating and
polishing facility,'' ``plating and polishing metal HAP,'' ``plating
and polishing process
[[Page 35749]]
tanks,'' ``repair,'' ``startup of the tank bath,'' and ``thermal
spraying.''
Finally, we are updating Table 1 of the rule entitled
``Applicability of General Provisions to Plating and Polishing Area
Sources,'' to reflect changes in the General Provisions that have
occurred since the rule was originally promulgated. Specifically, the
previous provisions relating to startup, shutdown, and malfunctions
have been removed, in light of the DC Circuit's decision in Sierra Club
v. EPA, 551 F.3d 1019 (DC Cir. 2008). The emissions standards for
plating and polishing area sources are expressed as management
practices, and these management practice requirements can be met at all
times. Therefore, exempting sources from meeting these standards during
periods of startup, shutdown, and malfunction is not appropriate.
VII. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563
This action is not a ``significant regulatory action'' under the
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is
therefore not subject to review under the Executive Order.
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
These final amendments clarify that the emission control requirements
of the plating and polishing area source rule do not apply to bench-
scale activities. Also, several technical corrections and
clarifications that do not make material changes in the rule's
requirements have been made to the rule text. No new burden is
associated with these requirements because the burden was included in
the approved information request (ICR) for the existing rule. The
Office of Management and Budget (OMB) has previously approved the
information collection requirements contained in the existing
regulations (40 CFR part 63 subpart WWWWWW) under the provisions of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has been assigned
OMB control number 2060-0623. The OMB control numbers for EPA's
regulations in 40 CFR are listed in 40 CFR part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act generally requires an agency to
prepare a regulatory flexibility analysis of any rule subject to notice
and comment rulemaking requirements under the Administrative Procedure
Act or any other statute unless the agency certifies that the rule
would not have a significant economic impact on a substantial number of
small entities. Small entities include small businesses, small not-for-
profit enterprises, and small governmental jurisdictions.
For the purposes of assessing the impacts of this final rule on
small entities, small entity is defined as: (1) a small business that
meets the Small Business Administration size standards for small
businesses at 13 CFR 121.201 (whose parent company has fewer than 500
employees for NAICS code 332813); (2) a small governmental jurisdiction
that is a government of a city, county, town, school district, or
special district with a population of less than 50,000; and (3) a small
organization that is any not-for-profit enterprise which is
independently owned and operated and is not dominant in its field.
After considering the economic impacts of this final rule on small
entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. We have
determined that the small entities in this area source category will
not incur any adverse impacts because this action makes only technical
corrections and clarifications that increase flexibility and does not
create any new requirements or burdens. No costs are associated with
these amendments to the NESHAP.
D. Unfunded Mandates Reform Act
This action contains no Federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for State, local, or Tribal governments or the private
sector. The action imposes no enforceable duty on any State, local or
Tribal governments or the private sector. Therefore, this action is not
subject to the requirements of sections 202 or 205 of the UMRA.
This action is also not subject to the requirements of section 203
of UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments. The technical
corrections and clarifications made through this action contain no
requirements that apply to such governments, impose no obligations upon
them, and will not result in any expenditures by them or any
disproportionate impacts on them.
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, as
specified in Executive Order 13132. The final rule makes certain
technical corrections and clarifications to the NESHAP for plating and
polishing area sources. These final corrections and clarifications do
not impose requirements on State and local governments. Thus, Executive
Order 13132 does not apply to the final rule.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This final action does not have Tribal implications, as specified
in Executive Order 13175 (65 FR 67249, November 6, 2000). This final
rule makes certain technical corrections and clarifications to the
NESHAP for plating and polishing area sources. These final corrections
and clarifications do not impose requirements on Tribal governments.
They also have no 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. Thus, Executive Order 13175 does not
apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997)
as applying to those regulatory actions that concern health or safety
risks, such that the analysis required under section 5-501 of the
Executive Order has the potential to influence the regulation. This
action is not subject to Executive Order 13045 because it makes
technical corrections and clarifications to the area source NESHAP for
plating and polishing area sources which is based solely on technology
performance.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not subject to Executive Order 13211 (66 FR 28355,
May 22, 2001) because it is not a significant regulatory action under
Executive Order 12866.
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) of 1995 (Pub. L. 104-113, section 12(d), 15 U.S.C. 272
note) directs EPA to use voluntary consensus
[[Page 35750]]
standards (VCS) in its regulatory activities, unless to do so would be
inconsistent with applicable law or otherwise impractical. The VCS are
technical standards (e.g., materials specifications, test methods,
sampling procedures, and business practices) that are developed or
adopted by VCS bodies. The NTTAA directs EPA to provide Congress,
through the Office of Management and Budget, explanations when the
Agency does not use available and applicable VCS.
This final rule does not involve technical standards. Therefore,
EPA did not consider the use of any VCS.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898 (59 FR 7629, February 16, 1994) establishes
Federal executive policy on environmental justice. Its main provision
directs Federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
EPA has 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 does not
affect the level of protection provided to human health or the
environment. The technical corrections and clarifications in this final
rule do not change the level of control required by the NESHAP.
K. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of Congress and to the Comptroller General
of the United States. EPA will submit a report containing these final
rule amendments and other required information to the U.S. Senate, the
U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of the final rule amendments in the
Federal Register. A major rule cannot take effect until 60 days after
it is published in the Federal Register. This action is not a ``major
rule'' as defined by 5 U.S.C. 804(2). This final rule will be effective
on September 19, 2011.

7. Section 63.11511 is amended by:
0
a. Adding, in alphabetical order, new definitions of ``bench-scale
plating or polishing,'' ``conversion coatings,'' ``major facility,''
``maintenance,'' ``metal HAP content,'' ``repair,'' and ``startup of
the tank bath''; and
0
b. Revising the definitions of ``bath,'' ``dry mechanical polishing,''
``electropolishing,'' ``fabric filter,'' ``flash electroplating,''
``metal coating operation,'' ``non-electrolytic plating,'' ``plating
and polishing facility,'' ``plating and polishing metal HAP,''
``plating and polishing process tanks,'' and ``thermal spraying.''
Sec. 63.11511 What definitions apply to this subpart?
* * * * *
Bath means the liquid contents of a tank, as defined in this
section, which is used for electroplating, electroforming,
electropolishing, or other metal coating processes at a plating and
polishing facility.
Bench-scale means any operation that is small enough to be
performed on a bench, table, or similar structure so that the equipment
is not directly contacting the floor.
* * * * *
Conversion coatings are coatings that form a hard metal finish on
an object when the object is submerged in a tank bath or solution that
contains the conversion coatings. Conversion coatings for the purposes
of this rule include coatings composed of chromium, as well as the
other plating and polishing metal HAP, where no electrical current is
used.
* * * * *
Dry mechanical polishing means a process used for removing defects
from and smoothing the surface of finished metals and formed products
after plating or thermal spraying with any of the plating and polishing
metal HAP, as defined in this section, using automatic or manually-
operated machines that have hard-faced abrasive wheels or belts and
where no liquids or fluids are used to trap the removed metal
particles. The affected process does not include polishing with use of
pastes, liquids, lubricants, or any other added materials.
* * * * *
Electropolishing means an electrolytic process performed in a tank
after plating 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. For the
purposes of this subpart, electropolishing does not include bench-scale
operations.
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.
Filters, for the purposes of this rule, include cartridge, fabric,
or HEPA filters, as defined in this section.
Flash electroplating means an electrolytic process performed in a
tank 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.
* * * * *
A major facility for HAP is any facility that emits greater than 10
tpy of any HAP, or that emits a combined total of all HAP of over 25
tpy, where the HAP used to determine the total facility emissions are
not restricted to only plating and polishing metal HAP nor from only
plating and polishing operations.
* * * * *
Maintenance is any process at a plating and polishing facility that
is performed to keep the process equipment or the facility operating
properly and is not performed on items to be sold as products.
* * * * *
Metal coating operation means any process performed either in a
tank that contains liquids or as part of a thermal spraying operation,
that applies one or more plating and polishing metal HAP, as defined in
this section, to the surface of parts and products used in
manufacturing. These processes include but are not limited to: non-
chromium electroplating; electroforming; electropolishing; non-
electrolytic metal coating processes, such as chromate conversion
coating, electroless nickel plating, nickel acetate sealing, sodium
dichromate sealing, and manganese phosphate coating; and thermal or
flame spraying.
Metal HAP content of material used in plating and polishing is the
HAP content as determined from an analysis or engineering estimate of
the HAP contents of the tank bath or solution, in the case of plating,
metal coating, or electropolishing; or the HAP content of the metal
coating being applied in the case of thermal spraying. Safety data
sheet (SDS) information may be used in lieu of testing or engineering
estimates but is not required to be used.
* * * * *
Non-electrolytic plating means a 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. Non-electrolytic plating is also called
electroless plating. Examples include chromate conversion coating,
nickel acetate sealing, electroless nickel plating, sodium dichromate
sealing, and manganese phosphate coating.
* * * * *
Plating and polishing facility means a facility engaged in one or
more of the
[[Page 35753]]
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
performed in a tank, 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 or thermal spraying. Plating
is performed in a tank or thermally sprayed so that a metal coating is
irreversibly applied to an object. Plating and polishing does not
include any bench-scale processes.
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 (as the
metal), and does not contain manganese in amounts greater than or equal
to 1.0 percent by weight (as the metal), 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
process is performed at an affected plating and polishing facility that
uses or has the potential to emit any of the plating and polishing
metal HAP, as defined in this section. The processes performed in
plating and polishing tanks include the following: Electroplating
processes other than chromium electroplating (i.e., non-chromium
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 clean, rinse or
wash parts prior to placing the parts in a plating and polishing
process tank, or subsequent to removing the parts from a plating and
polishing process tank. This term also does not include any bench-scale
operations.
* * * * *
Repair means any process used to return a finished object or tool
back to its original function or shape.
* * * * *
Startup of the tank bath is when the components or relative
proportions of the various components in the bath have been altered
from the most recent operating period. Startup of the bath does not
include events where only the tank's heating or agitation and other
mechanical operations are turned back on after being turned off for a
period of time.
* * * * *
Thermal spraying (also referred to as metal spraying or flame
spraying) is a process that uses or emits any of the plating and
polishing metal HAP, as defined in this section, in which a metallic
coating is applied by projecting heated, molten, or semi-molten metal
particles onto a substrate. Commonly-used thermal spraying methods
include high velocity oxy-fuel (HVOF) spraying, flame spraying,
electric arc spraying, plasma arc spraying, and detonation gun
spraying. This operation does not include spray painting at ambient
temperatures.
