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.

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.

-
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.
-
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.
-
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.''
-
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.

Statutory and Executive Order Reviews
-
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.
-
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.
-
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.
-
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.

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.

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.

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.

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.

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.

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.

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.

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. 0 8. Table 1 to Subart WWWWWW of Part 63 is revised to read as follows:
