40 CFR Part 63

[EPA-HQ-OAR-2002-0093; FRL-8304-2]
RIN 2060-AN10

National Emission Standards for Hazardous Air Pollutants: Surface
Coating of Automobiles and Light-Duty Trucks; National Emission
Standards for Hazardous Air Pollutants for Surface Coating of Plastic
Parts and Products

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is taking direct final action on amendments to the
National Emission Standards for Hazardous Air Pollutants: Surface
Coating of Automobiles and Light-Duty Trucks (Automobiles and Light-
Duty Trucks NESHAP) which were promulgated on April 26, 2004, under the
authority of section 112(d) of the Clean Air Act. The direct final rule
amends provisions in the Automobiles and Light-Duty Trucks NESHAP to
clarify the interaction between the Automobiles and Light-Duty Trucks
NESHAP and the National Emission Standards for Hazardous Air Pollutants
for Surface Coating of Plastic Parts and Products (Plastic Parts
NESHAP), to clarify the meaning of certain regulatory provisions, and
to correct certain errors identified in the regulatory text. EPA is
also taking direct final action on amendments to the Plastic Parts
NESHAP to clarify that screen printing is not subject to that rule.

DATES: The direct final rule is effective on June 25, 2007 without
further notice,

unless EPA receives adverse written comment or a public hearing is
requested. If we receive adverse comment or a request for a public
hearing, we will publish a timely withdrawal in the Federal Register
informing the public that this rule, or the relevant provisions of this
rule, will not take effect. Written comments must be received on or
before May 24, 2007 unless a public hearing is requested by May 4,
2007. If a public hearing is requested, written comments must be
received on or before June 8, 2007. If anyone contacts EPA requesting
to speak at a public hearing, a public hearing will be held on May 9,
2007.

SUPPLEMENTARY INFORMATION:
    Why is EPA using a direct final rule? EPA is publishing this rule
without a prior proposed rule because we view this as a
noncontroversial action and anticipate no adverse comment. This direct
final rule amends provisions in the Automobiles and Light-Duty Trucks
NESHAP to clarify the interaction between the Automobiles and Light-
Duty Trucks NESHAP and the Plastic Parts NESHAP, to clarify the meaning
of certain regulatory provisions, and to correct certain errors
identified in the regulatory text. The direct final rule also amends
the Plastic Parts NESHAP to clarify that screen printing is not subject
to that rule.
    However, in the ``Proposed Rules'' section of today's Federal
Register, we are publishing a separate document that will serve as the
proposed rule if adverse comments are received on this direct final
rule or a public hearing is requested, and the direct final rule is,
therefore, withdrawn. We will not institute a second comment period on
the proposed rule. Any parties interested in commenting must do so at
this time. For further information about commenting on this direct
final rule, see the ADDRESSES section of this document.
    If EPA receives adverse comment or a public hearing is requested,
we will publish a timely withdrawal in the Federal Register informing
the public that this direct final rule will not take effect. We would
address all public comments in any subsequent final rule based on the
proposed rule.
    If we receive adverse comment on a distinct provision of this
rulemaking, we will publish a timely withdrawal in the Federal Register
indicating which provisions we are withdrawing. The provisions that are
not withdrawn will become effective on the date set out above,
notwithstanding adverse comment on any other provision.
    Submitting CBI. Do not submit this information to EPA through
http://www.regulations.gov or e-mail. Clearly mark the part or all of the

information that you claim to be CBI. For CBI information on a disk or
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as
CBI and then identify electronically within the disk or CD ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.

I. Background

    On April 26, 2004, we issued the final Automobiles and Light-Duty
Trucks NESHAP (69 FR 22602). The final NESHAP established standards to
control organic hazardous air pollutant (HAP) emissions from new and
existing automobile and light-duty truck surface coating operations.
This action amends the final Automobiles and Light-Duty Trucks NESHAP
to clarify the interaction between that rule and the Plastic Parts
NESHAP, to clarify the meaning of certain regulatory provisions, and to
correct certain errors in the regulatory text. On April 19, 2004, we
issued the final Plastic Parts NESHAP (69 FR 20968). The final NESHAP
established standards to control organic hazardous air pollutant (HAP)
emissions from new and existing plastic parts coating operations.
Today's action amends the Plastic Parts NESHAP to clarify that screen
printing is not subject to that rule. None of the amendments will have
any effect on the stringency of the rules.

II. Amendments

    All of the amendments discussed below are amendments to the
Automobiles and Light-Duty Trucks NESHAP (40 CFR part 63, subpart
IIII), except for one amendment to the Plastic Parts NESHAP (40 CFR
part 63, subpart PPPP) which is discussed at the end of section II.A.
``Applicability.''

A. Applicability

    Plastic or composite body parts are used in many automobiles and
light-duty trucks. These parts are typically fabricated (molded,
stamped, formed, etc.) and prime coated at plastic or composites
molding facilities, and then sent to automobile or light-duty truck
assembly facilities where they receive an additional prime coat and
topcoat. The coating activities at plastic or composites molding
facilities were considered in the development of the Plastic Parts
NESHAP (40 CFR part 63, subpart PPPP) and are subject to that
regulation. The coating activities at automobile or light-duty truck
assembly facilities were considered in the development of the final
Automobiles and Light-Duty Trucks NESHAP and are subject to that
regulation.
    The application of ``topcoat to new automobile or new light-duty
truck bodies or body parts for new automobiles or new light-duty
trucks'' is used as an applicability criterion in 40 CFR 63.3081(b) of
the final Automobiles and Light-Duty Trucks NESHAP. The intent of this
applicability criterion was to keep the coating of plastic or composite
body parts at plastic or composites molding facilities, which is
subject to the Plastic Parts NESHAP, from being subject to the
Automobiles and Light-Duty Trucks NESHAP. The structure of this
applicability criterion was based on our knowledge, at the time, of the
application of prime coat to plastic or composite body parts at plastic
or composites molding facilities. Specifically, at the time we
developed the applicability criterion, we were unaware of any
application of topcoat to plastic or composite body parts occurring at
plastic or composites molding facilities.
    We have since learned that there is some application of topcoat to
plastic or composite body parts at plastic or composites molding
facilities. The applicability criterion in 40 CFR 63.3081(b) of the
Automobiles and Light-Duty Trucks NESHAP, therefore, could have the
unintended consequence of making coating at plastic and composite
molding facilities subject to Automobiles and Light-Duty Trucks NESHAP.
We have amended 40 CFR 63.3081(b) and added a definition of ``plastic
or composites molding facility'' to clarify that the application of
topcoat to plastic or composite body parts at a

plastic or composites molding facility does not trigger applicability
of this subpart as long as all of the body parts topcoated at the
plastic or composites molding facility for use in new automobiles or
new light-duty trucks were fabricated (molded, stamped, formed, etc.)
at that facility or at another plastic or composites molding facility
with the same owner or operator, none of the new vehicles in which
these body parts are used are assembled at the plastic or composites
molding facility, and the plastic or composites molding facility does
not topcoat all of the body parts for any single new automobile or new
light-duty truck.
    We are also amending the Plastic Parts NESHAP because there has
been some confusion as to whether that NESHAP regulates screen
printing. Specifically, the definition of the term ``coating'' in the
Plastic Parts NESHAP includes the word ``ink.'' Some screen printing is
done on plastic. Screen printing on plastic, however, is part of the
printing and publishing source category. The printing and publishing
source category is addressed in the National Emission Standards for the
Printing and Publishing Industry (40 CFR part 63, subpart KK). We are,
therefore, amending 40 CFR 63.4481 of the Plastic Parts NESHAP to
clarify that screen printing is not subject to the Plastic Parts
NESHAP.

B. Recordkeeping

    After publication of the final Automobiles and Light-Duty Trucks
NESHAP, a question was raised about the types of records required to be
kept under 40 CFR 63.3130(o). The question was whether these records
were limited to operating instructions, or whether other records, such
as construction blueprints, also needed to be maintained. We have
amended 40 CFR 63.3130(o) to clarify that the operating instructions
for each add-on control device and each continuous parameter monitoring
system must be kept on-site for the life of the equipment in a location
readily available to plant operators and inspectors.

C. Electrodeposition Primer

    An electrodeposition primer tank or system typically contains tens
of thousands of gallons of material. As a result, monthly material
usage for electrodeposition primer is typically determined by tracking
additions to the tank or system over the month. This contrasts to other
coating operations, such as topcoat or primer-surfacer, where monthly
usage of each material is typically determined by tracking additions to
a small (e.g., 500 gallon) day tank over the month and the change in
the amount of material in the day tank from the beginning of the month
to the end of the month.
    After publication of the final rule, we were asked if we could
clarify that material usage and other parameters relevant to
electrodeposition primer are determined based upon additions to the
tank or system over the month. We have amended 40 CFR 63.3161(e) to
clarify that for electrodeposition primer the mass fraction of organic
HAP, density and volume of each material used is to be determined for
each material added to the tank or system during the month. We have
amended 40 CFR 63.3161(f) to clarify that for electrodeposition primer
the volume fraction of coating solids is to be determined for each
material added to the tank or system during the month.
    The determination of capture efficiency is discussed in 40 CFR
63.3165 of the final rule. The introductory text to 40 CFR 63.3165 of
the final rule states that a bake oven air seal is not considered a
natural draft opening to a permanent total enclosure or a temporary
total enclosure provided the direction of air movement across the
interface between the bake oven air seal and the bake oven is into the
bake oven. This includes electrodeposition bake oven air seals. Capture
of emissions from electrodeposition bake ovens is also discussed in 40
CFR 63.3171(f) of the final rule. After publication of the final rule,
we were asked if we could clarify that electrodeposition bake oven air
seals were intended to be considered in the same manner under 40 CFR
63.3171(f) as they are considered in 40 CFR 63.3165 introductory text.
We have amended 40 CFR 63.3171(f) to clarify that an electrodeposition
bake oven air seal is not considered a natural draft opening provided
the direction of air movement across the interface between the bake
oven air seal and the bake oven is into the bake oven.

D. Transfer Efficiency

    The final rule requires that transfer efficiency be determined for
many coatings used in automobile or light-duty truck coating
operations. The final rule states that transfer efficiency may be
determined using ASTM Method D5066-91 (Reapproved 2001), Standard Test
Method for Determination of the Transfer Efficiency Under Production
Conditions for Spray Application of Automotive Paints-Weight Basis
(incorporated by reference, see 40 CFR 63.14), or the guidelines
presented in Protocol for Determining Daily Volatile Organic Compound
Emission Rate of Automobile and Light-Duty Truck Topcoat Operations,
EPA-450/3-88-018 (Docket ID No. OAR-2002-0093 and Docket ID No. A-2001-
22). The final rule provides default transfer efficiency values for
electrodeposition primer coatings, glass bonding primers, glass bonding
adhesives, and final repair coatings. The guidelines provide default
transfer efficiency values for certain specialty or low-use coatings
such as blackout and interior color.
    After publication of the final rule, a question was raised about
whether the default transfer efficiency values in the guidelines could
be used for chip resistant edge primer, lower body anti-chip coating
and underbody anti-chip coating. These types of coatings are not
explicitly mentioned in the guidelines, because the guidelines do not
discuss primer-surfacer operations in detail. We believe it is
appropriate to apply the default transfer efficiency values in the
guidelines to these types of coatings and are amending the rule
accordingly. Similar to blackout, lower-body anti-chip coating and chip
resistant edge primer are applied to relatively small areas of the
vehicle. Underbody anti-chip coatings are typically applied with
efficient airless applicators. Specifically, we have amended 40 CFR
63.3161(g) to provide default transfer efficiency values for these
types of coatings. We have also added definitions of ``chip resistant
edge primer,'' ``lower body anti-chip coating,'' and ``underbody anti-
chip coating,'' and revised the definitions of ``anti-chip coating,''
``deadener,'' and ``primer-surfacer'' to better identify the types of
coatings for which default transfer efficiency values can be used.

E. Equations

    We have corrected Equation 5 in 40 CFR 63.3161(l) by removing ``/
100'' from the end of the equation. This division by 100 is incorrect
because the transfer efficiency (TE) is expressed as a decimal value
rather than as a percentage.
    We have revised Equation 4 in Sec.  63.3165(e) by changing the
symbol ``Pi'' to ``Pv,i'' to emphasize that the panel test result in
this equation is expressed in mass (kg) of volatile organic compounds
(VOC) per volume (liter) of coating solids deposited. This helps
distinguish this equation from Equation 7 in 40 CFR 63.3165(e) where
the symbol ``Pm,i'' is used to emphasize that the panel test result in
that equation is expressed in mass (kg) of VOC per mass (kg) of coating
solids deposited.
    We have revised the description of the symbol
``Wvocc,i'' in Equations 6 and 7 in 40 CFR 63.3165(e) to
specify that the guidelines for combining analytical

VOC content and formulation solvent content are in Section 9 of the
Protocol for Determining Daily Volatile Organic Compound Emission Rate
of Automobile and Light-Duty Truck Coating Operations (Protocol). The
description of the symbol ``Wvocc,i'' in Equations 6 and 7
in 40 CFR 63.3165(e) of the final rule provided only a general
reference to the Protocol.
    We have corrected Equation 7 in 40 CFR 63.3165(e) by adding a
multiplier of ``100'' to the numerator of the equation. This multiplier
is needed in order for the result of the equation to be expressed as a
percentage.

F. Monitoring

    The temperature operating limits for thermal oxidizers, catalytic
oxidizers and condensers are identified as ``3-hour'' operating limits
in Table 1 of the final rule. The ``3-hour'' specification was
inadvertently omitted from 40 CFR 63.3167(a)(2), (b)(2), and (d)(2) of
the final rule. We have revised 40 CFR 63.3167(a)(2), (b)(2), and
(d)(2) to clarify that these operating limits are 3-hour averages.
    Catalyst activity testing and internal inspection of the catalyst
are specified in 40 CFR 63.3167(b)(6) of the final Automobiles and
Light-Duty Trucks rule. Similar specifications are provided in 40 CFR
63.4567(b)(4) of the Plastic Parts NESHAP. The specifications in the
Plastic Parts NESHAP include an explanation of how to proceed if
problems are found during annual catalyst activity testing or annual
internal inspection of the catalyst. This explanation was inadvertently
omitted from the final Automobiles and Light-Duty Trucks rule. We have
revised 40 CFR 63.3167(b)(6) to explain how to proceed if problems are
found during annual catalyst activity testing or annual internal
inspection of the catalyst.
    The exceptions provided in 40 CFR 63.3167(f), for capture devices
that are part of a PTE or that capture emissions from a downdraft spray
booth or from a flashoff area or bake oven associated with a downdraft
spray booth, were inadvertently omitted from the entry for ``Emission
capture system that is not a PTE'' in Table 1 of the final rule. We
have revised Table 1 of the final rule to make the entry for ``Emission
capture system that is not a PTE'' consistent with 40 CFR 63.3167(f) of
the final rule and to correct a typographical error.

G. Uncounted Capture and Control

    Some facilities have capture systems or add-on control devices
installed and operated to control VOC emissions which they do not need
to take into account in order to demonstrate compliance with the
emission limitations for organic hazardous air pollutants in the final
rule. After publication of the final rule, we were asked whether
testing and monitoring requirements apply to capture systems or add-on
control devices that are not taken into account in demonstrating
compliance with the emission limitations for organic hazardous air
pollutants in the final rule. Other surface coating NESHAP have
separate compliance demonstration provisions for ``emission rate
without add-on control'' and ``emission rate with add-on control''. We
intended to provide the same flexibility in the Automobiles and Light-
Duty Trucks NESHAP. We, therefore, have added new sections 40 CFR
63.3169 and 40 CFR 63.3174 and added a definition of ``controlled
coating operation'' to clarify that the requirements for capture system
or add-on control device reporting, recordkeeping, performance tests,
monitoring, operating parameters, capture efficiency, add-on control
device efficiency, destruction efficiency, or removal efficiency do not
apply to capture systems or add-on control devices which the owner or
operator chooses not to take into account when demonstrating compliance
with the applicable emission limitations. If, at a later date, the
owner or operator decides to take any such capture system or add-on
control device into account when demonstrating compliance with the
emission limitations, then, at that time, the owner or operator must
comply with the reporting, recordkeeping, performance tests,
monitoring, operating parameters, capture efficiency, add-on control
device efficiency, destruction efficiency, or removal efficiency for
that capture system or add-on control device.

H. Definitions

    In addition to the definition changes described above, we have made
several other changes to the definitions in the final rule. After
publication of the final rule, we were asked if we could clarify that
``bake oven air seals'' may be present both on bake ovens associated
with spray booths and on bake ovens associated with electrodeposition
primer operations. We have revised the definition of ``bake oven air
seal'' to clarify that both bake ovens associated with spray booth and
electrodeposition primer bake ovens may have bake oven air seals. We
have also revised the definition of ``spray booth air seal'' to make it
consistent with the definition of ``bake oven air seal.'' The
definition of ``bake oven air seal'' referred to ``entry or entry
vestibule to or an exit or exit vestibule'' whereas the definition of
``spray booth air seal'' inadvertently referred only to ``entry
vestibule or exit vestibule.'' We have revised the definition of
``touchup bottle'' to allow the container size to be up to 0.25 liters
and to clarify that the applicator may be a brush or other non-
atomizing applicator.

III. Statutory and Executive Order Reviews

A. Executive Order 12866, Regulatory Planning and Review

    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.
OMB has previously approved the information collection requirements
contained in the existing regulations (40 CFR part 63, subpart IIII)
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501, et
seq., and has assigned OMB control number 2060-0550, EPA ICR No.
2045.03. A copy of the Information Collection Request (ICR) may be
obtained from Ms. Susan Auby by mail at the Office of Environmental
Information, Collection Strategies Division (2822), EPA, 1200
Pennsylvania Avenue, NW., Washington, DC 20460, by e-mail at
<EMAIL_ADDRESS>or by calling<PHONE_NUMBER>.

    Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, or disclose or
provide information to or for a Federal agency. This includes the time
needed to review instructions; develop, acquire, install, and utilize
technology and systems for the purposes of collecting, validating, and
verifying information, processing and maintaining information, and
disclosing and providing information; adjust the existing ways to
comply with any previously applicable instructions and requirements;
train personnel to be able to respond to a collection of information;
search data sources; complete and review the collection of information;
and transmit or otherwise disclose the information.
    An agency may not conduct or sponsor, and a person is not required
to respond to a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Analysis

    The Regulatory Flexibility Act (RFA) 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 will not have a significant economic impact on a substantial
number of small entities. Small entities include small businesses,
small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of today's direct final rule
on small entities, small entity is defined as: (1) A small business
according to Small Business Administration size standards for companies
identified by NAICS codes 336111 (automobile manufacturing) and 336112
(light truck and utility vehicle manufacturing) with 1,000 or fewer
employees or by NAICS code 323113 (commercial screen printing) with 500
or fewer employees; (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.
Based on the above definition, there are no small entities presently
engaged in automobile and light-duty truck surface coating. While there
are small entities presently engaged in commercial screen printing,
today's direct final rule amendments would not impose any requirements
on commercial screen printers.
    After considering the economic impacts of the final rule on small
entities, EPA has concluded and hereby certifies that this action will
not have a significant economic impact on a substantial number of small
entities. This is based on the observation that this action affects no
small entities since none are engaged in the surface coating of
automobiles and light-duty trucks, and no requirements are imposed on
commercial screen printers.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments and the private sector. Under section 202 of the UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures to State, local, and tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
1 year. Before promulgating a rule for which a written statement is
needed, section 205 of the UMRA generally requires us to identify and
consider a reasonable number of regulatory alternatives and adopt the
least costly, most cost-effective, or least burdensome alternative that
achieves the objectives of the rule. The provisions of section 205 do
not apply when they are inconsistent with applicable law. Moreover,
section 205 allows EPA to adopt an alternative other than the least
costly, most cost-effective, or least burdensome alternative if the
Administrator publishes with the final rule an explanation why that
alternative was not adopted. Before EPA establishes any regulatory
requirements that may significantly or uniquely affect small
governments, including tribal governments, it must have developed under
section 203 of the UMRA a small government agency plan. The plan must
provide for notifying potentially affected small governments, enabling
officials of affected small governments to have meaningful and timely
input in the development of EPA regulatory proposals with significant
Federal intergovernmental mandates, and informing, educating, and
advising small governments on compliance with the regulatory
requirements.
    EPA has determined that the direct final rule amendments do not
contain a Federal mandate that may result in expenditures of $100
million or more for State, local, and tribal governments, in the
aggregate, or the private sector in any 1 year. The direct final rule
amendments add no additional burden on sources. Thus, the direct final
rule amendments are not subject to the requirements of sections 202 and
205 of the UMRA.

E. Executive Order 13132, Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that 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.''
    The direct final rule amendments do not have federalism
implications. They 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. No
facilities subject to the direct final rule amendments are owned by
State or local governments. Therefore, State and local governments will
not have any direct compliance costs resulting from the direct final
rule amendments. Furthermore, the direct final rule amendments do not
require these governments to take on any new responsibilities. Thus,
Executive Order 13132 does not apply to the direct final rule
amendments.

F. Executive Order 13175, Consultation and Coordination With Indian
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000),
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by tribal officials in the development of regulatory
policies that have tribal implications.'' The direct final rule
amendments do not have tribal implications as specified in Executive
Order 13175. They will not have substantial 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, because we are not
aware of any Indian tribal governments or communities affected by the
direct final rule amendments. Thus, Executive Order 13175 does not
apply to the direct final rule amendments.

G. Executive Order 13045, Protection of Children From Environmental
Health Risks and Safety Risks

    Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) Is determined to be ``economically significant'' as
defined under Executive Order 12866, and (2) concerns an environmental
health or safety risk that EPA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, the Agency must evaluate the environmental health or
safety effects of the planned rule on children, and explain why the
planned regulation is preferable to other potentially effective and
reasonably feasible alternatives considered by the Agency.
    EPA interprets Executive Order 13045 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. The direct final rule
amendments are not subject to Executive Order 13045 because they are
based solely on technology performance.

H. Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

    The direct final rule amendments are not subject to Executive Order
13211, ``Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use'' (66 FR 28355 (May 22, 2001))
because they are not a significant regulatory action under Executive
Order 12866.

I. National Technology Transfer and Advancement Act

    The direct final rule amendments do not involve technical
standards. Therefore, EPA is not considering the use of any VCS.

J. 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 the Congress and to the Comptroller
General of the United States. EPA will submit a report containing the
direct final rule amendments and other required information to the
United States Senate, the United States House of Representatives, and
the Comptroller General of the United States prior to publication of
the direct final rule amendments in the Federal Register. A ``major
rule'' cannot take effect until 60 days after it is published in the
Federal Register. The direct final rule amendments are not a ``major
rule'' as defined by 5 U.S.C. 804(2). The direct final rule amendments
will be effective on June 25, 2007.

Sec.  63.3161  How do I demonstrate initial compliance?

* * * * *
    (e) Determine the mass fraction of organic HAP, density, and volume
used. Follow the procedures specified in Sec.  63.3151(a) through (c)
to determine the mass fraction of organic HAP and the density and
volume of each coating and thinner used during each month. For
electrodeposition primer operations, the mass fraction of organic HAP,
density, and volume used must be determined for each material added to
the tank or system during each month.
    (f) Determine the volume fraction of coating solids for each
coating. You must determine the volume fraction of coating solids
(liter of coating solids per liter of coating) for each coating used
during the compliance period by a test or by information provided by
the supplier or the manufacturer of the material, as specified in
paragraphs (f)(1) and (2) of this section. For electrodeposition primer
operations, the volume fraction of solids must be determined for each
material added to the tank or system during each month. If test results
obtained according to paragraph (f)(1) of this section do not agree
with the information obtained under paragraph (f)(2) of this section,
the test results will take precedence unless, after consultation, the
facility demonstrates to the satisfaction of the enforcement authority
that the facility's data are correct.

    (g) * * * For blackout, chip resistant edge primer, interior color,
in-line repair, lower body anti-chip coatings, or underbody anti-chip
coatings, you may assume 40 percent transfer efficiency for air
atomized spray, 55 percent transfer efficiency for electrostatic spray
and high volume-low pressure spray, and 80 percent transfer efficiency
for airless spray.

    (3) As an alternative, you may choose to express the results of
your panel tests in units of mass of VOC per mass of coating solids
deposited and convert such results to a percent using Equation 7 of
this section. If you panel test representative coatings, then you may
convert the panel test result for each representative coating either to
a unique percent capture efficiency for each coating grouped with that
representative coating by using coating specific values for the mass of
coating solids deposited per mass of coating used, mass fraction VOC,
transfer efficiency, and mass fraction solids in Equations 7 and 8 of
this section; or to a composite percent capture efficiency for the
group of coatings by using composite values for the group of coatings
for the mass of coating solids deposited per mass of coating used and
average values for the mass of VOC per volume of coating, average
values for the group of coatings for mass fraction VOC, transfer
efficiency, and mass fraction solids in Equations 7 and 8 of this
section. If you panel test each coating, then you must convert the
panel test result for each coating to a unique percent capture
efficiency for that coating by using coating specific values for the
mass of coating solids deposited per mass of coating used, mass
fraction VOC, transfer efficiency, and mass fraction solids in
Equations 7 and 8 of this section. Panel test results expressed in
units of mass of VOC per mass of coating solids deposited must be

c. Revising paragraph (b)(6); and
0
d. Revising the second sentence of paragraph (d)(2) to read as follows:

Sec.  63.3167  How do I establish the add-on control device operating
limits during the performance test?

* * * * *
    (a) * * *
    (2) * * * This average combustion temperature is the minimum 3-hour
average operating limit for your thermal oxidizer.
* * * * *
    (b) * * *
    (2) Use all valid data collected during the performance test to
calculate and record the average temperature just before the catalyst
bed and the average temperature difference across the catalyst bed
maintained during the performance test. The minimum 3-hour average
operating limits for your catalytic oxidizer are the average
temperature just before the catalyst bed maintained during the
performance test of that catalytic oxidizer and 80 percent of the
average temperature difference across the catalyst bed maintained
during the performance test of that catalytic oxidizer, except during
periods of low production, the latter minimum operating limit is to
maintain a positive temperature gradient across the catalyst bed. A low
production period is when production is less than 80 percent of
production rate during the performance test of that catalytic oxidizer.
* * * * *
    (6) You must develop and implement an inspection and maintenance
plan for your catalytic oxidizer(s) for which you elect to monitor
according to paragraph (b)(4) or (b)(5) of this section. The plan must
address, at a minimum, the elements specified in paragraphs (b)(6)(i)
through (iii) of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e.,
conversion efficiency) following the manufacturer's or catalyst
supplier's recommended procedures. If problems are found during the
catalyst activity test, you must replace the catalyst bed or take other
corrective action consistent with the manufacturer's recommendations.
    (ii) Monthly external inspection of the catalytic oxidizer system,
including the burner assembly and fuel supply lines for problems and,
as necessary, adjust the equipment to assure proper air-to-fuel
mixtures.
    (iii) Annual internal inspection of the catalyst bed to check for
channeling, abrasion, and settling. If problems are found during the
annual internal inspection of the catalyst, you must replace the
catalyst bed or take other corrective action consistent with the
manufacturer's recommendations. If the catalyst bed is replaced and is
not of like or better kind and quality as the old catalyst, then you
must conduct a new performance test to determine destruction efficiency
according to Sec.  63.3166. If a catalyst bed is replaced and the
replacement catalyst is of like or better kind and quality as the old
catalyst, then a new performance test to determine destruction
efficiency is not required and you may continue to use the previously
established operating limits for that catalytic oxidizer.

Sec.  63.3169  What are the requirements for a capture system or add-on
control device which is not taken into account when demonstrating
compliance with the applicable emission limitations?

    You may have capture systems or add-on control devices which you
choose not to take into account when demonstrating compliance with the
applicable emission limitations. For any such capture system or add-on
control device, you are not required to comply with the requirements of
Sec. Sec.  63.3093, 63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and
63.3160 through 63.3168 with regard to notification, reporting,
recordkeeping, performance tests, monitoring, operating parameters,
capture efficiency, add-on control device efficiency, destruction
efficiency, or removal efficiency. If, at a later date, you decide to
take any such capture system or add-on control device into account when
demonstrating compliance with the emission limitations, then at that
time you must comply with the requirements of Sec. Sec.  63.3093,
63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and 63.3160 through
63.3168 with regard to notification, recordkeeping, performance tests,
monitoring, operating parameters, capture efficiency, add-on control
device efficiency, destruction efficiency, and removal efficiency, as
applicable, for that capture system or add-on control device.

8. Section 63.3171 is amended by revising paragraph (f) to read as
follows:

Sec.  63.3171  How do I demonstrate initial compliance?

* * * * *
    (f) Capture of electrodeposition bake oven emissions. You must show
that the electrodeposition bake oven meets the criteria in sections 5.3
through 5.5 of Method 204 of appendix M to 40 CFR part 51 and directs
all of the exhaust gases from the bake oven to an add-on control
device. For purposes of this showing, an electrodeposition bake oven
air seal is not considered a natural draft opening provided you
demonstrate that the direction of air movement across the interface
between the bake oven air seal and the bake oven is into the bake oven.
You may use lightweight strips of fabric or paper, or smoke tubes to
make such demonstrations. You cannot count air flowing from an
electrodeposition bake oven air seal into an electrodeposition bake
oven as air flowing through a natural draft opening unless you elect to
treat that

electrodeposition bake oven air seal as a natural draft opening.

recordkeeping, performance tests, monitoring, operating parameters,
capture efficiency, add-on control device efficiency, destruction
efficiency, or removal efficiency. If, at a later date, you decide to
take any such capture system or add-on control device into account when
demonstrating compliance with the emission limitations, then at that
time you must comply with the requirements of Sec. Sec.  63.3093,
63.3100, 63.3110, 63.3120, 63.3130, 63.3131, and 63.3160 through

0
a. Revising the definitions of ``Anti-chip coating,'' ``Bake oven air
seal,'' ``Controlled coating operation,'' ``Deadener,'' ``In-line
repair,'' ``Primer-surfacer,'' ``Spray booth air seal,'' and ``Touchup
bottle.''
0
b. Adding in alphabetical order definitions of ``Chip resistant edge
primer,'' ``Lower body anti-chip coating,'' ``Plastic or composites
molding facility,'' and ``Underbody anti-chip coating'' to read as
follows:

Sec.  63.3176  What definitions apply to this subpart?

* * * * *
    Anti-chip coating means a specialty type of coating designed to
reduce stone chipping damage. Anti-chip coating may be applied to broad
areas of the vehicle or to selected vehicle surfaces that are most
vulnerable to impingement by stones and other road debris. Anti-chip
coating is typically applied after the electrodeposition primer and
before the topcoat. Anti-chip coating is a type of primer-surfacer.
* * * * *
    Bake oven air seal means an entry or entry vestibule to or an exit
or exit vestibule from a bake oven which isolates the bake oven from
the area immediately preceding (for an entry or entry vestibule) or
immediately following (for an exit or exit vestibule) the bake oven. No
significant VOC generating activity takes place in a bake oven air
seal. Fresh air is supplied into a bake oven air seal and is then
directed in part into the bake oven and in part into the area
immediately preceding or immediately following the bake oven. All types
of bake ovens, including ovens associated with spray booths and
electrodeposition primer bake ovens, may have bake oven air seals.
* * * * *
    Chip resistant edge primer means an anti-chip coating applied to
the leading edge of parts such as the hood or roof.
* * * * *
    Controlled coating operation means a coating operation from which
some or all of the organic HAP emissions are routed through a capture
system and an add-on control device which are taken into account when
demonstrating compliance with an emission limitation in this subpart.
* * * * *
    Deadener means a specialty coating applied to selected vehicle
surfaces primarily for the purpose of reducing the sound of road noise
in the passenger compartment.
* * * * *
    In-line repair means the operation performed and coating(s) applied
to correct damage or imperfections in the topcoat on parts that are not
yet on a completely assembled motor vehicle. The curing of the
coatingspplied in these operations is accomplished at essentially the
same temperature as that used for curing the previously applied
topcoat. Also referred to as high bake repair or high bake reprocess.
In-line repair is considered part of the topcoat operation.
* * * * *
    Lower body anti-chip coating means an anti-chip coating applied to
lower body surfaces such as rocker panels, valence panels, lower
portions of doors, or lower portions of fenders.
* * * * *
    Plastic or composites molding facility means a facility where the
purchase cost of capital equipment used for plastic or composites
molding, including presses, tooling, and associated material processing
and handling equipment, is greater than the purchase cost of capital
equipment used for the surface coating of new automobile or new light-
duty truck bodies or body parts for new automobiles or new light-duty
trucks.
    Primer-surfacer means an intermediate protective coating applied on
the electrodeposition primer and under the topcoat. Primer-surfacer
provides adhesion, protection, and appearance properties to the total
finish. Primer-surfacer may also be called guide coat or surfacer.
