practices (40 CFR 63.8(c)(1)) and that set out the requirements of a
quality control program for monitoring equipment (40 CFR 63.8(d)).
f. 40 CFR 63.752(a) Recordkeeping
    We are proposing to revise the General Provisions table entry for
40 CFR 63.10(b)(2)(i) by changing the ``yes'' in column 2 to a ``no.''
Section 63.10(b)(2)(i) describes the recordkeeping requirements during
startup and shutdown. These recording provisions are no longer
necessary because the EPA is proposing that recordkeeping and reporting
applicable to normal operations will apply to startup and shutdown. In
the absence of special provisions applicable to startup and shutdown,
such as a startup and shutdown plan, there is no reason to retain
additional recordkeeping for startup and shutdown periods.
    We are proposing to revise the General Provisions table entry for
40 CFR 63.10(b)(2)(ii) by changing the ``yes'' in column 2 to a ``no.''
Section 63.10(b)(2)(ii) describes the recordkeeping requirements during
a malfunction. The EPA is proposing to add such requirements to 40 CFR
63.752(a). The regulatory text we are proposing to add differs from the
General Provisions it is replacing in that the General Provisions
requires the creation and retention of a record of the occurrence and
duration of each malfunction of process, air pollution control and
monitoring equipment. The EPA is proposing that this requirement apply
to any failure to meet an applicable standard and is requiring that the
source record the date, time and duration of the failure rather than
the ``occurrence.'' The EPA is also proposing to add to 40 CFR
63.752(a) a requirement that sources keep records that include a list
of the affected source or equipment and actions taken to minimize
emissions, an estimate of the quantity of each regulated pollutant
emitted over the standard for which the source failed to meet the
standard and a description of the method used to estimate the
emissions. Examples of such methods would include mass balance
calculations, measurements when available or engineering judgment based
on known process parameters (e.g., coating HAP content and application
rate or control device efficiencies). The EPA is proposing to require
that sources keep records of this information to ensure that there is
adequate information to allow the EPA to determine the severity of any
failure to meet a standard and to provide data that may document how
the source met the general duty to minimize emissions when the source
has failed to meet an applicable standard.
    We are proposing to revise the General Provisions table entry for
40 CFR 63.10(b)(2)(iv) by changing the ``yes'' in column 2 to a ``no.''
When applicable, the provision requires sources to record actions taken
during SSM events when actions were inconsistent with their SSM plan.
The requirement is no longer appropriate because SSM plans will no
longer be required. The requirement previously applicable under 40 CFR
63.10(b)(2)(iv)(B) to record actions to minimize emissions and record
corrective actions is now applicable by reference to 40 CFR 63.752(a).
    We are proposing to revise the General Provisions table entry for
40 CFR 63.10(b)(2)(v) by changing the ``yes'' in column 2 to a ``no.''
When applicable, the provision requires sources to record actions taken
during SSM events to show that actions taken were consistent with their
SSM plan. The requirement is no longer appropriate because SSM plans
will no longer be required.
g. 40 CFR 63.753 Reporting
    We are proposing to revise the General Provisions table entry for
40 CFR 63.10(d)(5) by changing the ``yes'' in column 2 to a ``no.''
Section 63.10(d)(5) describes the reporting requirements for startups,
shutdowns and malfunctions. To replace the General Provisions reporting
requirement, the EPA is proposing to add reporting requirements to 40
CFR 63.753(a). The replacement language added to 40 CFR 63.753(a)
differs from the General Provisions requirement in that it eliminates
periodic SSM reports

as a stand-alone report. We are proposing language that requires
sources that fail to meet an applicable standard at any time to report
the information concerning such events in the semi-annual reporting
period already required under this rule. We are proposing that the
report must contain the number, date, time, duration and the cause of
such events (including unknown cause, if applicable), a list of the
affected source or equipment, an estimate of the quantity of each
regulated pollutant emitted over any emission limit and a description
of the method used to estimate the emissions.
    Examples of such methods would include mass balance calculations,
measurements when available or engineering judgment based on known
process parameters (e.g., coating HAP content and application rates and
control device efficiencies). The EPA is proposing this requirement to
ensure that there is adequate information to determine compliance, to
allow the EPA to determine the severity of the failure to meet an
applicable standard and to provide data that may document how the
source met the general duty to minimize emissions during a failure to
meet an applicable standard.
    We would no longer require owners or operators to determine whether
actions taken to correct a malfunction are consistent with an SSM plan,
because plans would no longer be required. The proposed amendments
would, therefore, eliminate the cross reference to 40 CFR
63.10(d)(5)(i) that contains the description of the previously required
SSM report format and submittal schedule from this section. These
specifications would be no longer necessary because the events would be
reported in otherwise required reports with similar format and
submittal requirements.
    As discussed above, we are proposing to revise the General
Provisions table entry for 40 CFR 63.10(d)(5), by changing the ``yes''
in column 2 to a ``no.'' Section 63.10(d)(5)(ii) describes an immediate
report for startups, shutdown and malfunctions when a source failed to
meet an applicable standard, but did not follow the SSM plan. We will
no longer require owners and operators to report when actions taken
during a startup, shutdown or malfunction were not consistent with an
SSM plan, because plans would no longer be required to allow the EPA to
determine the severity of the failure to meet an applicable standard
and to provide data that may document how the source met the general
duty to minimize emissions during a failure to meet an applicable
standard.
4. Technical Amendments to the Aerospace NESHAP
    The EPA is also proposing the following technical corrections:
     Revising 40 CFR 63.743(a)(2) to match the section title in
40 CFR 63.5.
     Revising 40 CFR 63.743(a)(8) to correct the reference to
paragraph 63.6(i)(12)(iii)(B) by changing the ``(1)'' to an ``(i).''
     Revising 40 CFR 63.744(a) to correct and clarify the
format of the reference to 40 CFR 63.744(a)(1) through (4).
     Correct the ordering of 40 CFR 63.744(a)(3) and (4);
currently paragraph (a)(4) is printed before (a)(3).
     Correcting the paragraph numbering for 40 CFR
63.746(b)(4)(ii)(C) by changing paragraph (C) from a lower case to
upper case ``C.''
     Correcting the numbering of the tables in 40 CFR 63.745 to
account for the proposed addition of Table 1 to that section to include
specialty coating limits.
     Revising 40 CFR 63.749(d)(4) to correct the references to
40 CFR 63.749(d)(4)(i) through (d)(4)(iv) and (e).
     Revising 40 CFR 63.750(g)(6)(i) to remove the letters
``VR/FD'' that were inadvertently included.
5. Amendments To Simplify Recordkeeping and Reporting for Compliant
Coatings
    The EPA is proposing to revise 40 CFR 63.750 to include alternative
compliance demonstration provisions for all coatings subject to the
Aerospace NESHAP (primers, topcoats, specialty coatings and chemical
milling maskants). If the manufacturer's supplied formulation data or
calculation of HAP and VOC content indicate that the coating meets the
organic HAP and VOC content emission limits for its coating type, as
specified in 40 CFR 63.745(c) and 63.747(c), then the owner or operator
would not be required to demonstrate compliance for these coatings
using the test method and calculations specified in 40 CFR 63.750(c),
(e), (k) and (m) or to keep the associated records and submit the
associated reports associated with these methods and calculations.
Instead, the owner or operator would be able to rely on the
manufacturers' formulation data and calculation of the HAP or VOC
content to demonstrate compliance. However, the owner or operator would
still be required to maintain purchase records and manufacturer's
supplied data sheets for these compliant coatings. Owners or operators
of facilities using these coatings would also still be required to
handle and transfer these coatings in a manner that minimizes spills,
apply these coatings using one or more of the specified application
techniques and comply with inorganic HAP emission requirements.
    This change is being proposed to reduce unnecessary recordkeeping
and avoid the need for owners or operators to perform tests to measure
VOC and HAP content and to perform certain calculations that can be
done by the coating manufacturer based on coating formulation data.
When the Aerospace NESHAP was originally promulgated, the original
compliance demonstration and recordkeeping requirements were needed
because the product data sheets provided by coating manufacturers did
not routinely provide VOC content in grams per liter (less water and
exempt solvents) or HAP content in grams per liter (less water). As a
result, it was necessary for the facilities to calculate the VOC or HAP
content in this format to demonstrate compliance.
    Since promulgation of the Aerospace NESHAP, coating manufacturers
now commonly provide VOC content of the coatings, in grams per liter
(less water and exempt solvents) on the product data sheets, based on
coating formulation. Therefore, the coating manufacturer's
documentation can be used to demonstrate compliance, when available, in
place of the compliance demonstrations based on VOC measurements and
compliance calculations.
    We are proposing that this alternative apply to all coatings
subject to the Aerospace NESHAP, including specialty coatings,
topcoats, primers and chemical milling maskants. Due to the existence
of the Aerospace NESHAP for nearly 20 years and the prevalence of state
and regional VOC regulations for many types of coatings, coating
manufacturers have come to recognize the value of providing
documentation of HAP and VOC content to their customers to facilitate
compliance demonstrations with state and federal regulations. For all
coatings subject to the Aerospace NESHAP, the EPA has determined that
onsite purchase records and the manufacturer's supplied data sheets for
the coatings will provide sufficient information to establish
compliance with the content limit standards in the Aerospace NESHAP.
    If a facility elects to comply with the averaging provisions in 40
CFR 63.743(d), the facility is also required to comply with all related
averaging provisions in the Aerospace NESHAP for all coatings included
in averaging (e.g., compliance determination provisions in 40 CFR
63.749(d) and (h); procedures and methods in 40 CFR 63.750(d), (f), (l)
and (n); recordkeeping

provisions in 40 CFR 63.752(c) and (f); and reporting provisions in
63.753(c) and (e)). Note that, in complying with the current averaging
provisions, facilities may already use manufacturers' data for coatings
to determine the organic HAP and VOC weight fraction of coatings to
perform the calculations in 40 CFR 63.750(d), (f), (l) and (n).

F. What compliance dates are we proposing?

    The EPA is proposing that all of the amendments being proposed in
this action would be effective on the date 60 days after these proposed
amendments are final, with one exception. The one exception is that
existing specialty coating affected sources (i.e., existing on the date
these changes are final) would have 1 year after the date this rule is
final to comply with the standards for specialty coatings proposed in
40 CFR 63.745(c)(5) and (6) (HAP and VOC limits for specified coatings)
and the provisions in 40 CFR 63.745(f) (coating application equipment)
and 40 CFR 63.745(g) (control of inorganic HAP emissions). The EPA is
proposing this compliance schedule so that existing sources would have
time to develop the recordkeeping and reporting systems needed to
comply with the requirements for specialty coatings. Facilities may
also need this time to identify alternative coatings for those that are
not currently compliant with the HAP or VOC content limits and to take
any steps needed to upgrade specialty coating operations to comply with
the application equipment requirements in 40 CFR 63.745(f) and the
inorganic HAP emissions requirements in 40 CFR 63.745(g).
    The tasks necessary for existing facilities to comply with the
other proposed amendments require no time or resources. Therefore, EPA
believes that existing facilities will be able to comply with the other
proposed amendments, including those related to SSM periods, as soon as
the final rule is effective, which will be the date 60 days after
publication of the final rule. Therefore, the EPA is specifically
soliciting comment and additional data on the burden of complying with
the other proposed amendments.

V. Summary of Cost, Environmental and Economic Impacts

A. What are the affected sources?

    The EPA estimates, based on the responses to the 2011 ICR, that
there are 144 major source facilities that are engaged in aerospace
manufacturing and rework surface coating operations. The EPA estimates
that 109 facilities likely would be affected by the proposed limits for
specialty coatings and the requirements to use high-efficiency
application equipment for specialty coatings, also based on the
responses to the 2011 ICR.

B. What are the air quality impacts?

    The EPA estimates that annual HAP emissions from specialty coatings
are about 360 tpy; inorganic HAP emissions are about 5 tpy and the
remainder are organic HAP. The estimated emission reductions are 58
tons of HAP, which would be achieved from the proposed regulation of
specialty coatings. The EPA estimated that these emission reductions
would result from the proposed requirements to use high-efficiency
application equipment and also from the application of the HAP content
limits to specialty coatings.

C. What are the cost impacts?

    The EPA estimates that the annual cost impacts would be about
$590,000 per year. The cost impacts would be attributed to monitoring
and recordkeeping costs for complying with the specialty coating HAP
content limits. The cost per facility was estimated based on the number
of specialty coatings used at each facility, as reported in the 2011
ICR. The costs are based on an assumption of 1 hour of technical labor
for annual recordkeeping and reporting for each specialty coating used
by a facility, plus additional management and clerical hours
representing a fraction of the technical labor hours.
    The EPA does not have sufficient data from the 2011 ICR to estimate
the total cost impacts for specialty coatings having to comply with the
proposed high-efficiency application equipment requirement. Because
high-efficiency application equipment generates less coating overspray
than conventional equipment, the costs of upgrading to new equipment
can be offset by cost savings from reduced coating consumption and
reduced spray booth filter maintenance. For these reasons, many
facilities are likely to have already switched to high-efficiency
application methods for specialty coating operations, as they are
already required to for primer and topcoat application operations. For
example, the average volume of specialty coatings used per facility is
3,000 gallons per year, based on the 2011 ICR data. The estimated
purchase cost for a professional quality HVLP spray gun is $700 for the
gun and hoses. If the average facility had to purchase three new spray
guns, and the facility was spending an average of $30 per gallon of
spray applied coating, the facility would need to see a decrease in
coating consumption of only 70 gallons per year (about a 3-percent
reduction) to recover the initial cost of those three spray guns in 1
year.
    The EPA expects some additional potential cost savings from the
proposal to include an alternative compliance demonstration provision
in 40 CFR 63.750(c), (e), (k) and (m). However, we do not have
sufficient data to estimate the cost savings associated with the
proposed alternative compliance demonstration. However, the estimated
cost to perform an analysis of VOC content according to EPA Method 24,
based on published vendor data, is about $575 per sample. Because the
proposed alternative compliance demonstration would allow facilities to
use coating manufacturers' documentation of VOC content based on
coating composition, the cost of these coating analyses using EPA
Method 24 would be avoided.
    The EPA's cost analyses are documented in the memorandum,
Methodology for Estimating Control Costs for Specialty Coating
Operations in the Aerospace Source Category, January 2014, in the
docket for this rulemaking.
    EPA is specifically soliciting comment and additional data on the
cost impacts associated with using coatings that are compliant with the
proposed limits for specialty coatings.

D. What are the economic impacts?

    Economic impact analyses focus on changes in market prices and
output levels. If changes in market prices and output levels in the
primary markets are significant enough, impacts on other markets are
also examined. Both the magnitude of costs needed to comply with the
rule and the distribution of these costs among affected facilities can
have a role in determining how the market will change in response to a
rule.
    This rule applies to the surface coating and related operations at
facilities that are major sources and are engaged, either in part or in
whole, in the manufacture or rework of commercial, civil or military
aerospace vehicles or components. The proposed rule would add
recordkeeping and reporting provisions for specialty coating
operations, but would not change the compliance costs for operations
already being regulated by the existing emission standards. Therefore,
the annual costs were calculated for only the 109 Aerospace
Manufacturing and Rework Facilities that reported having specialty
coating operations.

    The estimated annual costs for this proposed rule are less than $1
million in the first year and in succeeding years (less than $850,000
in the first year and less than $600,000 in succeeding years). These
costs are estimated for the 109 facilities that, based on information
reported by facilities, appear to have specialty coating operations.
Thus, the average cost per facility is less than $10,000 per year.
These costs are small compared to sales for the companies in aerospace
manufacturing and reworking. For example, in 2012 the average annual
value of shipments (a rough estimate of sales) for firms in the
category of ``other aircraft parts and auxiliary equipment
manufacturing'' was almost $50 million (Source: U.S. Census Bureau,
2012 Economic Census for NAICS 336413 for 2012). In this case the cost-
to-sales estimate would be approximately 0.02 percent of sales for each
firm. Costs this small would not have significant market impacts,
whether they were absorbed by the firm or passed on as price increases.
    The EPA does not know of any firms that are small entities and
using specialty coatings that are potentially subject to this proposed
rule. Because no small firms face control costs, there is no
significant impact on small entities. Therefore, we do not expect these
proposed amendments to have a significant impact on a substantial
number of small entities.

E. What are the benefits?

    We anticipate this rulemaking to reduce organic and inorganic HAP
emissions by approximately 58 tons each year. These avoided emissions
will result in improvements in air quality and reduced negative health
effects associated with exposure to air pollution of these emissions.
However, we have not quantified or monetized the benefits of reducing
these emissions for this rulemaking because the estimated costs for
this action are less than $100 million.

VI. Request for Comments

    We solicit comments on all aspects of this proposed action. In
addition to general comments on this proposed action, we are also
interested in additional data that may improve the risk assessments and
other analyses. We are specifically interested in receiving any
improvements to the data used in the site-specific emissions profiles
used for risk modeling. Such data should include supporting
documentation in sufficient detail to allow characterization of the
quality and representativeness of the data or information. Section VII
of this preamble provides more information on submitting data.

VIII. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was
therefore not submitted to the OMB for review.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have
been submitted for approval to the OMB under the PRA. The ICR document
that the EPA prepared has been assigned EPA ICR number 1687.10. You can
find a copy of the ICR in the docket for this rule, and it is briefly
summarized here.
    Respondents are owners or operators of aerospace manufacturing and
rework operations. The proposed rule would add recordkeeping and
reporting provisions for specialty coating operations, but would not
change the recordkeeping and reporting provisions for any other types
of operations. Therefore, of the 144 Aerospace Manufacturing and Rework
Facilities subject to the Aerospace NESHAP, the annual costs for
increased recordkeeping and reporting would apply to only the 109
Aerospace Manufacturing and Rework Facilities that reported having
specialty coating operations. Respondents must keep records of the
specialty coatings used at the facility, including the name and VOC
content of the coating, the HAP and VOC emitted per gallon of coating
and the monthly volume of each coating used. Respondents must also
submit semiannual reports of noncompliance. Recordkeeping and reporting
of monitored parameters related to air pollution control technologies
is required if controls are used to demonstrate compliance with the
standards. The reports and records will be used to determine compliance
with the standards.
    Respondents/affected entities: Aerospace manufacturing and rework
facilities using specialty coatings.
    Respondent's obligation to respond: Mandatory (40 CFR part 63,
subpart GG).
    Estimated number of respondents: 109 facilities using specialty
coatings.
    Frequency of response: Initially, occasionally and semiannually.
    Total estimated burden: 6,914 hours (per year) for the responding
facilities and 148 hours (per year) for the agency. These are estimates
for the average annual burden for the first 3 years after the rule is
final. Burden is defined at 5 CFR 1320.3(b).
    Total estimated cost: $695,570 (per year), which includes no
annualized

capital or operation and maintenance costs, for the responding
facilities and $8,740 (per year) for the agency. These are estimates
for the average annual cost for the first 3 years after the rule is
final.
    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 the
EPA's regulations in 40 CFR are listed in 40 CFR part 9. To comment on
the agency's need for this information, the accuracy of the provided
burden estimates and any suggested methods for minimizing respondent
burden, the EPA has established a public docket for this rule, which
includes this ICR, under Docket ID No. EPA-HQ-OAR-2014-0830.
    Submit your comments on the Agency's need for this information, the
accuracy of the provided burden estimates and any suggested methods for
minimizing respondent burden to the EPA using the docket identified at
the beginning of this rule. You may also send your ICR-related comments
to OMB's Office of Information and Regulatory Affairs via email to
<EMAIL_ADDRESS>Attention: Desk Officer for the EPA.
Since OMB is required to make a decision concerning the ICR between 30
and 60 days after receipt, OMB must receive comments no later than
March 19, 2015. The EPA will respond to any ICR-related comments in the
final rule.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic
impact on a substantial number of small entities under the RFA. This
action will not impose any requirements on small entities. No
facilities meeting the Small Business Administration's definition of a
small business would face significant control costs, based on the
economic impact analysis completed for this action. The results of this
analysis are summarized in section V.D of this preamble and can be
found in the memorandum, Economic Impact Analysis for Proposed National
Emission Standards for Aerospace Manufacturing and Rework Facilities,
December 3, 2014. A copy of this memorandum is in the docket for this
rulemaking.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or
more as described in the UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. The action imposes
no enforceable duty on any state, local or tribal governments or the
private sector.

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.

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

    This action does not have tribal implications as specified in
Executive Order 13175. No tribal facilities are known to be engaged in
the aerospace manufacturing or rework surface coating operations that
would be affected by this action. Thus, Executive Order 13175 does not
apply to this action.

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

    This action is not subject to Executive Order 13045 because it is
not economically significant as defined in Executive Order 12866, and
because the EPA does not believe the environmental health or safety
risks addressed by this action present a disproportionate risk to
children. This action's health and risk assessments are contained in
sections III.A and B and sections IV.B and C of this preamble.

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

    This action is not subject to Executive Order 13211 because it is
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed
by this action will not have potential disproportionately high and
adverse human health or environmental effects on minority, low-income
or indigenous populations.
    These proposed standards will improve public health and welfare,
now and in the future, by reducing HAP emissions contributing to
environmental and human health impacts. These reductions in HAP
associated with the rule are expected to benefit all populations.
    To examine the potential for any environmental justice issues that
might be associated with the Aerospace Manufacturing and Rework source
category, we evaluated the distributions of HAP related cancer and non-
cancer risks across different social, demographic and economic groups
within the populations living near the facilities where this source
category is located. The methods used to conduct demographic analyses
for this proposed rule are described in the document, Risk and
Technology Review--Analysis of Socio-Economic Factors for Populations
Living Near Aerospace Facilities, which may be found in the docket for
this rulemaking (Docket ID No. EPA-HQ-OAR-2014-0830).
    In the demographics analysis, we focused on populations within 50
km of the facilities in this source category with emissions sources
subject to the MACT standard. More specifically, for these populations,
we evaluated exposures to HAP that could result in cancer risks of 1-
in-1 million or greater. We compared the percentages of particular
demographic groups within the focused populations to the total
percentages of those demographic groups nationwide. The results of this
analysis are documented in the document, Risk and Technology Review--
Analysis of Socio-Economic Factors for Populations Living Near
Aerospace Facilities.

3. Section 63.742 is amended by revising the definitions for ``Chemical
milling maskant''; ``Softener''; and ``Stripper'' to read as follows:

Sec.  63.742  Definitions.

* * * * *
    Chemical milling maskant means a coating that is applied directly
to aluminum components to protect surface areas when chemical milling
the component with a Type I or Type II etchant. Type I chemical milling
maskants are used with a Type I etchant and Type II chemical milling
maskants are used with a Type II etchant. This definition does not
include bonding maskants, critical use and line sealer maskants and
seal coat maskants. Additionally, maskants that must be used with a
combination of Type I or II etchants and any of the above types of
maskants (i.e., bonding, critical use and line sealer and seal coat)
are also not included in this definition. (See also Type I and Type II
etchant definitions.)
* * * * *
    Softener means a liquid that is applied to an aerospace vehicle or
component to degrade coatings such as primers, topcoats and specialty
coatings specifically as a preparatory step to subsequent depainting by
non-chemical based depainting equipment. Softeners may contain VOC, but
shall not contain any HAP as determined from MSDS's or manufacturer
supplied information.
* * * * *
    Stripper means a liquid that is applied to an aerospace vehicle or
component to remove permanent coatings such as primers, topcoats and
specialty coatings.

any affected source, including associated air pollution control
equipment and monitoring equipment, in a manner consistent with safety
and good air pollution control practices for minimizing emissions. The
general duty to minimize emissions does not require the owner or
operator to make any further efforts to reduce emissions if levels
required by the applicable standard have been achieved. Determination
of whether a source is operating in compliance with operation and
maintenance requirements will be based on information available to the
Administrator which may include, but is not limited to, monitoring
results, review of operation and maintenance procedures, review of
operation and maintenance records and inspection of the source.
