National Emission Standards for Hazardous Air Pollutants: Paint
Stripping and Miscellaneous Surface Coating Operations at Area Sources
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: In this action, EPA proposes national emission standards for
hazardous air pollutants (NESHAP) for area sources engaged in paint
stripping and miscellaneous surface coating operations. EPA has listed
``Paint Stripping,'' ``Plastic Parts and Products (Surface Coating),''
and ``Autobody Refinishing Paint Shops'' as area sources of hazardous
air pollutants (HAP) that contribute to the risk to public health in
urban areas under the Integrated Urban Air Toxics Strategy. These three
source categories are being combined into one set of standards for the
purposes of this rulemaking. Paint stripping operations subject to the
standards being proposed include the use of methylene chloride-
containing chemicals to remove paint and other coatings. Plastic parts
and products surface coating operations include the application of
coatings to miscellaneous parts and/or products made of metal or
plastic, or combinations of metal and plastic. Autobody refinishing
includes the application of coating to motor vehicles and mobile
equipment. These proposed standards, when final, would require all
methylene chloride (MeCl) containing paint stripping and miscellaneous
surface coating operations at area sources to comply with equipment
requirements and/or management practices that minimize specific HAP
emissions. The standards would also establish training requirements for
persons who spray apply coatings. These standards, when final, would
apply to all area sources that perform methylene chloride-containing
paint stripping and miscellaneous surface coating activities, except
when other NESHAP apply.

B. Does this action apply to me?
Categories and entities potentially affected by the proposed rule
are MeCl--containing paint stripping operations and miscellaneous
surface coating operations located at area sources. An area source is
defined in CAA section 112(a) as any stationary source of HAP that is
not a major source, and a major source is defined as any stationary
source or group of stationary sources located within a contiguous area
and under common control that emits, or has the potential to emit,
considering controls, in the aggregate, 10 tons per year (tpy) of any
single HAP or 25 tpy of any combination of HAP. For the purposes of
this proposal, paint stripping operations are those that involve the
use of MeCl for the partial or complete removal of surface coatings
from wood, metal or plastic substrates at area sources as either (1) an
independent activity where paint stripping is the principle activity at
the source or (2) an activity incidental to the principle activity
(e.g., surface coating, inspection, maintenance, etc.) at the source.
We consider paint stripping activities that use less than 150 gallons
per year to be incidental to the principle activity and those using 150
gallons or more to be performing paint stripping as a principle
activity. Miscellaneous surface coating operations are those that
involve the application of coatings at area sources to (1)
miscellaneous parts and/or products made of metal or plastic, or
combinations of metal and plastic; or (2) motor vehicles and mobile
equipment (e.g., heavy duty-trucks, buses, construction equipment,
self-propelled vehicles and equipment that may be drawn and/or driven
on a roadway), hereinafter referred to as autobody refinishing. In
general, the facilities and entities potentially affected by the
proposed rule are covered under the North American Industrial
Classification System (NAICS) Codes listed in the following table.
However, facilities classified under other NAICS codes may be subject
to the proposed standards if they meet the applicability criteria.

II. Background Information for Proposed Area Source Standards
A. What is the regulatory development background for the proposed
standards for paint stripping and miscellaneous surface coating
operations?
Section 112 of the Clean Air Act (CAA) requires EPA to develop
NESHAP for both major and area sources that are listed for regulation
under CAA section 112(c). As stated earlier, a major source is defined
in CAA section 112(a) as any stationary source or group of stationary
sources located within a contiguous area and under common control that
emits, or has the potential to emit, considering controls, in the
aggregate, 10 tons per year (tpy) of any single HAP or 25 tpy of any
combination of HAP. An area source is any stationary source that is not
a major source. Thus, area sources are those sources of HAP that do not
emit nor have the potential to emit HAP at or above the 10 or 25 tpy
thresholds.
CAA section 112(k)(3)(B) requires EPA to develop a list of at least
30 HAP which, as a result of area source emissions, pose the greatest
threat to public health in the largest number of urban areas. We refer
to these HAP as the ``urban HAP.'' Section 112(c)(3) of the CAA directs
EPA to identify source categories or subcategories of area
[[Page 52962]]
sources that represent 90 percent of the emissions of the urban HAP.
On July 19, 1999, EPA published its Integrated Urban Air Toxics
Strategy, which included both the list of urban HAP and the initial
list of area source categories (64 FR 38706). The initial list of area
source categories included ``Paint Stripping Operations''. On June 26,
2002 and November 22, 2002, EPA added ``Autobody Refinishing Paint
Shops (67 FR 43112)'' and ``Plastic Parts and Products (Surface
Coating) (67 FR 70427)'', respectively, to the list of area source
categories. A primary goal of the Integrated Urban Air Toxics Strategy
is to achieve a 75 percent reduction in cancer incidence attributable
to HAP emitted from stationary sources in urban areas.
Sierra Club sued EPA, alleging a failure to complete standards for
the area source categories listed pursuant to CAA section 112(c)(3)and
(k)(3)(B) within the timeframe specified by the statute. See Sierra
Club v. Johnson, No. 01-1537, (D.D.C.). On March 31, 2006, the court
issued an order requiring EPA to promulgate standards under CAA section
112(d) for those area source categories listed pursuant to CAA section
112(c)(3) and (k)(3)(B). Among other things, the order requires that,
by December 15, 2007, EPA complete standards for certain area source
categories.
In this action, EPA is proposing standards for the following area
source categories: Paint stripping, plastic parts and products (surface
coating), and autobody refinishing. In developing this proposed rule,
we fully analyzed these three listed source categories and found that
it is both reasonable and technically feasible to regulate emissions
from these three source categories by a single set of emission
standards. The processes, emission points, emission characteristics,
and emission controls for plastic parts and products surface coating
and autobody refinishing are very similar. Additionally, paint
stripping is often performed as part of the surface preparation for
both plastic parts and autobody refinishing which, by regulating within
the scope of a single set of standards, reduces the burden of complying
with multiple standards on the sources performing both the paint
stripping and subsequent coating. This single set of emission standards
that addresses all three categories also minimizes the cost of
developing, permitting, and enforcing the standards. For purposes of
this preamble and proposed rule, the term ``paint stripping and
miscellaneous surface coating'' is used to indicate that the three area
source categories of paint stripping, plastic parts and products
(surface coating), and autobody refinishing have been treated as a
single source category for purposes of developing this rule.
Early in the development of standards to implement EPA's Integrated
Urban Strategy, the States expressed concern over the burden and
resources that would be required for the States to take delegation for
the implementation of the area source rules listed as part of the
strategy. Specifically, States were concerned that implementing Federal
requirements, in lieu of established State programs, would be overly
burdensome with little or no additional emission reductions for certain
source categories. In these discussions, the States acknowledged the
provisions in CAA section 112(l) as a route for providing them this
reduction of burden and flexibility in accepting delegation of some of
the area source standards. Guidance on the provisions of CAA section
112(l) are presented in 40 CFR 63 Subpart E which provides certain
administrative (i.e., monitoring, recordkeeping, and reporting)
criteria for an alternative program to be considered equivalent. This
guidance provides States with information regarding the necessary
components for their program to be considered equivalent. EPA believes
some States may have programs that address the emissions from the
surface coating of motor vehicles and mobile equipment that are at
least as effective as the proposed standards and encourages States to
consider utilizing these provisions in lieu of implementing the
proposed standards.
The EPA is seeking comment on (1) whether or not the States are
interested in utilizing the Section 112(l) alternative program
approach, and (2) what technical assistance the States may need to
develop equivalency determinations.
B. Where in the Code of Federal Regulations (CFR) will these standards
be codified?
The CFR is a codification of the general and permanent rules
published in the Federal Register by the Executive departments and
agencies of the Federal Government. The code is divided into 50 titles
that represent broad areas subject to Federal Regulation. When final,
these proposed standards will be published in Title 40, Protection of
the Environment, part 63, subpart HHHHHH: National Emission Standards
for Hazardous Air Pollutants: Paint Stripping and Miscellaneous Surface
Coating Operations.
C. What criteria are used in the development of these NESHAP?
CAA section 112(d)(5) authorizes EPA to issue alternative emission
standards for area sources in lieu of the authorities provided in CAA
sections 112(d)(2) and 112(f). Specifically, section 112(d)(5), which
is entitled ``Alternative Standard for Area Sources,'' provides:
With respect only to categories and subcategories of area
sources listed pursuant to subsection (c) of this section, the
Administrator may, in lieu of the authorities provided in paragraph
(2) and subsection (f) of this section, elect to promulgate
standards or requirements applicable to sources in such categories
or subcategories which provide for the use of generally available
control technologies or management practices by such sources to
reduce emissions of hazardous air pollutants.
Thus, CAA section 112(d)(5) authorizes EPA to promulgate standards
under section 112(d)(5) that provide for the use of generally available
control technologies or management practices (GACT), instead of issuing
maximum achievable control technology (MACT) standards pursuant to CAA
section 112(d)(2) and (d)(3). The statute does not set any condition
precedent for issuing standards under CAA section 112(d)(5) other than
that the area source category or subcategory at issue must be one that
EPA listed pursuant to CAA section 112(c)(3), which is the case in this
proposal.
When setting a GACT standard for an area source category as opposed
to a MACT standard, EPA must ensure that the GACT standard is
consistent with the requirements of CAA section 112(d)(5) and have a
reasonable basis for its GACT determination. Thus, in developing
standards for area sources of HAP emissions, EPA evaluates the control
technologies and management practices that reduce HAP emissions that
are generally available for each area source category, and, in
determining GACT, may establish standards on either (or both) generally
available control technologies or (and) management practices that
reduce the emission of HAP. EPA's analysis supporting the proposed GACT
requirements is discussed in detail in section IV of this preamble.
D. What are the sources of emissions and the HAP for which these area
source categories were listed?
EPA listed the area source paint stripping category pursuant to CAA
section 112(c)(3) based on emissions of MeCl contained in paint
stripper formulations. The emissions of MeCl comes from evaporative
losses during the use or storage of MeCl. EPA listed
[[Page 52963]]
the area source miscellaneous coating operations category pursuant to
section 112(c)(3) based on emissions of cadmium, chromium, lead
compounds (lead), manganese and nickel compounds that are in the
coatings, as part of the pigment in topcoats or for the corrosion
protection in primers. For purposes of this proposal we will refer to
these HAP as the ``target HAP.''
The anticipated national impacts of these proposed standards is
summarized in section V of this preamble.
E. What are the health effects associated with the pollutants emitted
by paint stripping and miscellaneous surface coating operations?
Emissions data collected in the development of this proposed rule
shows that HAP emitted from paint stripping and miscellaneous surface
coating operations are associated with a variety of adverse health
effects. These adverse health effects include chronic health disorders
(e.g., central nervous system effects, blood disorders, cancer) and
acute health disorders (e.g., irritation of eyes, nose and throat, with
long-term impairment of lung function possible at high acute
exposures). The proposed rule protects air quality and promotes the
public health by reducing the emissions of the HAP for which the three
source categories at issue in this proposed rule were listed.
F. How has EPA regulated major sources in the same industrial sectors
(similar sources) and what has EPA learned about available control
technologies and management practices from regulating these major
sources?
Major sources performing paint stripping and surface coating of
miscellaneous parts and/or products made of metal or plastic, or
combinations of metal and plastic; or motor vehicles and mobile
equipment (e.g., heavy duty-trucks, buses, construction equipment,
self-propelled vehicles and equipment that may be drawn and/or driven
on a roadway), were addressed in different surface coating NESHAP
requiring MACT level of control, of which the last NESHAP was
promulgated in 2004. Major sources must currently be in compliance with
those surface coating NESHAP.
Paint stripping was a separately listed major source category under
CAA section 112 (c)(1), however, during the data gathering phase EPA
determined that there were no major source paint stripping operations
conducted independent of surface coating. Therefore, all paint
stripping operations were covered in each surface coating NESHAP, as
part of the cleaning material used for surface preparation activities.
Each NESHAP assumed that the initial emission control technology would
be reduction of the usage of HAP cleaners or implementation of
management practices to reduce the evaporative losses from these
cleaning activities.
The data gathering for the major source categories revealed that
when the coatings are spray-applied, it was common practice to perform
application of the coatings within the confines of a spray booth to
minimize worker exposure. This limited the dispersion of the HAP to the
parts being coated as solids in the dry coating film, deposition onto
the walls, floor, and grates of the spray booths in which they are
applied, or some of the HAP particles would be entrained in the spray
booth exhaust air. We have learned, as part of the data gathering phase
of this area source proposal that although most, if not all, sources
are spray applying these coatings in a spray booth, not all of the
spray booths are capable of capturing and controlling the target HAP
(the HAP for which the area source categories at issue here were listed
pursuant to CAA section 112(c)(3).
III. Proposed NESHAP for Paint Stripping and Miscellaneous Coating
Operations at Area Sources
A. What are the affected area sources?
The sources that would be affected by the proposed standards are
area sources engaged in paint stripping using MeCl, and/or engaged in
coating of miscellaneous parts and/or products made of metal or
plastic, or combinations of metal and plastic, or autobody refinishing.
The proposed standards would not apply to any of these operations that
are specifically covered under another area source NESHAP (e.g., the
NESHAP for Defense Land Systems and Miscellaneous Equipment currently
under development). While these sources are not currently listed
pursuant to CAA section 112(c)(3) or 112(k)(3)(b), we intend to list
them under these provisions of the act.
B. What are the HAP and primary sources of emissions for which these
source categories were listed?
Paint Stripping Operations
The primary source of emissions from paint stripping operations and
the HAP for which this source category was listed pursuant to CAA
section 112(c)(3) (the ``target HAP'') is the MeCl contained in paint
stripper formulations. The primary source of the MeCl emissions in this
source category comes from evaporative losses during the use or storage
of MeCl.
Miscellaneous Coating Operations
The primary sources of emissions from miscellaneous coating
operations are the metal pigments that are in the coatings and/or
refinish material. The target HAP for which these source categories
were listed are the heavy metals including cadmium, chromium, lead,
manganese and nickel compounds. The primary source of emissions of
these HAP are the spray application of the coatings and curing process.
The heavy metals are contained primarily in the coatings (e.g.,
primers and the pigments in topcoats) and include compounds of lead
(Pb), trivalent chromium (Cr-III), or hexavalent chromium (Cr-VI), plus
compounds of other metals that are considered HAP, such as cadmium,
manganese, and nickel. The metal HAP compounds are emitted as the
coatings are atomized during spray application. A substantial fraction
of coating that is atomized does not reach the part and becomes what is
termed ``overspray.'' The fraction that becomes overspray depends on
many variables, but two of the most important are the type of equipment
and the skill of the painter. Some overspray lands on surfaces of the
spray booth and the masking paper that is usually placed around the
surface being sprayed, but the rest of the overspray is drawn into the
spray booth exhaust system. If the spray booth has filters, most of the
overspray is captured by the filters; otherwise, it is exhausted to the
atmosphere.
After coating application, the spray gun must be cleaned to remove
the remaining coating before it cures and to prepare it for the next
coating job. Solvents used for equipment cleaning may contain the same
HAP as the coatings they remove. Spray guns are usually cleaned in a
device, commonly referred to as an enclosed spray gun washer, that
consists of a solvent reservoir and a covered enclosure that dispenses
solvent for gun cleaning. The enclosure may hold the gun for automated
gun cleaning. During gun cleaning, HAP from the cleaning solvent and
the coating may be emitted as the cleaning solvent is sprayed through
the gun during cleaning from the equipment that stores and dispenses
the cleaning solvent while it is opened.
C. Do the proposed standards apply to my source?
The area source requirements specified in the proposed rule would
apply to your source if your source (or
[[Page 52964]]
facility) is an area source that performs (1) paint stripping using
MeCl-containing chemicals or (2) surface coating using spray equipment.
The area source requirements specified in the proposed rule would
not apply if your paint stripping or surface coating operations meet
any of the following:
Paint stripping or surface coating performed on-site at
installations owned or operated by the Armed Forces of the United
States (including the Coast Guard and the National Guard of any such
State), or the National Aeronautics and Space Administration because
these activities will be subject to the area source NESHAP for military
operations which is in development.
Paint stripping or surface coating of military munitions
manufactured by or for the Armed Forces of the United States (including
the Coast Guard and the National Guard of any such State) or equipment
directly and exclusively used for the purposes of transporting
munitions manufactured by or for the Armed Forces of the United States
(including the Coast Guard and the National Guard of any such State)
because these activities will be subject to the area source NESHAP for
military operations which is in development.
D. What emissions control requirements is EPA proposing?
This section describes the proposed emissions control requirements
for paint stripping and miscellaneous coating operations. The basis for
these proposed requirements is discussed in section IV, below.
Paint Stripping Operations
All sources conducting paint stripping involving the use of MeCl
must implement management practice standards that reduce emissions of
MeCl by minimizing evaporative losses of MeCl.
In addition to the management practices, sources that use 150 gal
or more of paint stripper containing MeCl, per year would need to
develop and implement a MeCl minimization plan consisting of a written
plan with the criteria to evaluate the necessity of MeCl in the
stripping operations and management techniques to minimize MeCl
emissions when it is needed in the paint stripping operation.
The MeCl minimization plan evaluation criteria would involve only
using a MeCl-containing paint stripper when an alternative on-site
stripping method or material is incapable of accomplishing the work as
determined by the operator. Alternative methods to reduce MeCl usage
may include: (1) Non-MeCl-containing chemical strippers; (2) mechanical
stripping; (3) blasting (including dry or wet media); or (4) thermal
and cryogenic decomposition.
The management practices that would be required to be contained in
the plan include optimizing stripper application conditions, reducing
exposure of stripper to the air, and practicing proper storage and
disposal of materials containing MeCl. Sources would be required to
submit the plan either to EPA or to the delegated state permit
authority, keep a written copy of the plan on site and post a placard
or sign outlining the evaluation criteria and management techniques in
each area where MeCl-containing paint stripping operations occur.
Miscellaneous Coating Operations
All sources conducting surface coating operations involving spray-
applied coatings would need to apply the coatings with a high volume,
low pressure (HVLP) spray gun, electrostatic spray gun, or a gun
demonstrated to be equal in transfer efficiency to an HVLP spray gun.
All spray-applied coatings would need to be applied in a prep station
or spray booth, with a full roof and at least three complete walls or
complete side curtains, ventilated so that air is drawn into the booth.
The exhaust from the prep station or spray booth would need to be
fitted with fiberglass or polyester fiber filters or some other filter
technology demonstrated to achieve at least 98 percent capture
efficiency of paint overspray. As explained further below, we are
proposing that the combination of these technologies are GACT for the
miscellaneous surface coating operations.
Additionally, sources would be required to comply with the
management practices by demonstrating that (1) all painters that spray-
apply coatings are certified and (2) that all spray gun cleaning
performed by spraying HAP solvent through the gun is performed in an
enclosed spray gun cleaner or by cleaning the disassembled gun parts by
hand (i.e., spraying HAP solvent through a gun outside of a gun cleaner
would be prohibited). The painter would need to be certified as having
completed classroom and hands-on training in the proper selection,
mixing, and application of coatings. Refresher training would need to
be repeated at least once every 5 years. The initial and refresher
training would need to address the following topics:
Surface preparation (prep).
Spray gun set up and operation and spray technique for
different types of coatings to improve transfer efficiency and minimize
coating usage and overspray.
Routine spray booth and filter maintenance.
Paint mixing, matching, and applying.
Resolving paint application problems.
Finish defects causes and cures.
Safety precautions.
Environmental compliance.
E. What are the initial compliance requirements?
If your facility is a new source (one that began construction or
reconstruction after the date this rule is proposed) and you use MeCl
in your paint stripping operations or you spray apply coatings, you
would be required to comply with all of the requirements established in
this subpart as of the date of promulgation of the final rule or upon
startup, whichever is later.
If your facility is an existing source (one that began construction
or reconstruction before the date this rule is proposed), you would be
required to comply with the requirements no later than 2 years after
the date the final rule is published. In addition, each painter would
need to comply with the training requirements of the rule no later than
60 days after hiring. Painters would be allowed to use training that
was completed within 5 years prior to the date training is required to
meet this requirement. All painters would need to receive refresher
training and be re-certified every 5 years.
To demonstrate initial compliance for paint stripping operations,
you would need to:
Certify that you have implemented a best management
practices plan, and
If you are a source that uses 150 gal or more of paint
stripper containing MeCl, per year, certify that you have developed and
implemented a MeCl minimization plan consisting of a written plan with
the criteria to evaluate the necessity of MeCl in the stripping
operations and management techniques to minimize MeCl emissions when it
is needed in the paint stripping operation.
To demonstrate initial compliance for miscellaneous surface coating
operations, you would need to:
Certify that all coatings are sprayed in booths or prep
stations that are fitted with filters.
Certify that all spray guns are HVLP or an equivalent.
Certify that all painters that apply coatings using a
spray gun have completed the training described in section III.D. of
this preamble.
[[Page 52965]]
Certify that all gun cleaning is performed in enclosed gun
cleaners or by hand.
After the compliance date for your source, you would have 120 days
if you are a new source, and 30 days if you are an existing source, to
submit a notification of compliance status to the EPA or a delegated
State or local air pollution control agency.
You would also be required to submit an initial notification to the
EPA or the delegated agency that you are subject to the standard. You
would have 120 days after startup or publication of the final rule
(whichever is later) to submit the initial notification if you are a
new source. If you are an existing source, you would have 1 year after
publication of the final rule to submit the initial notification.
If your facility is an existing source, you would be required to
comply with the requirements no later than 2 years after the date the
final rule is published. In addition, each painter would need to comply
with the training requirements of the rule no later than 60 days after
hiring. Painters would be allowed to use training that was completed
within 5 years prior to the date training is required to meet this
requirement. All painters would need to receive refresher training and
be re-certified every 5 years.
F. What are the continuous compliance requirements?
To demonstrate continuous compliance, you would need to continually
maintain the emission control requirements (i.e., management practices
and equipment requirements) that are described in section III.D. of
this preamble.
G. What are the notification, recordkeeping, and reporting
requirements?
You would be required to submit an initial notification to the EPA
or the delegated agency that you are subject to the standard. If you
are a new source, you would have 120 days after startup or publication
of the final rule (whichever is later) to submit the initial
notification. If you are an existing source, you would have 1 year
after publication of the final rule to submit the initial notification.
After the compliance date for your source, you would have 120 days
if you are a new source and 30 days if you are an existing source to
submit a notification of compliance status to the EPA or a delegated
State or local air pollution control agency.
Paint Stripping Operations
For paint stripping operations, you would need to maintain records
demonstrating the following:
Annual usage of MeCl in paint strippers is below 150
gallons (if you are a source qualifying for the best management
practices, only); or
You have complied with the MeCl minimization plan.
If you are required to have a MeCl minimization plan, you would
also be required to submit annual compliance reports in which you
certify that the source is in compliance, or report the date, duration,
and description of any deviations from the MeCl minimization plan that
occurred and the corrective actions taken.
Miscellaneous Coating Operations
For miscellaneous coating operations, you would need to maintain
records demonstrating the following:
All spray painters are trained and certified;
Any spray booth filters or particulate controls that are
not fiberglass or polyester fiber filters achieve at least 98 percent
efficiency; and
Any spray guns that do not meet the definition of HVLP or
electrostatic spray gun have been demonstrated to achieve comparable
transfer efficiency.
Spray gun cleaning is being performed manually or in an
enclosed gun cleaner when solvent is being atomized through the gun as
part of the cleaning process.
You would also be required to submit annual compliance reports in
which you certify that the source is in compliance, or report the date,
duration, and description of any deviations from the specified control
requirements that occurred and the corrective actions taken.
IV. Rationale for Selecting the Proposed Standards
A. What area source categories are affected by this proposal?
As discussed above, this rulemaking covers facilities engaged in
MeCl paint stripping and spray applied surface coating of parts and/or
products made of metal or plastic, or combinations of metal and
plastic; and refinishing of motor vehicles and mobile equipment which
are a source of emissions of MeCl, cadmium, chromium, lead, manganese
and nickel compounds which are the target HAP described above.
B. How did we select the affected source?
In selecting the affected source for emission standards, our
primary goal is to ensure that all emission points responsible for the
emissions of the target HAP (i.e., MeCl & the heavy metals) in each
listed source category are controlled as specified in CAA section
112(d)(5), described previously in Section II.C. The affected source
also serves to establish when new source standards should be applied.
Specifically, the General Provisions in subpart A of 40 CFR part 63
define the terms ``construction'' and ``reconstruction'' with reference
to the term ``affected source'' (40 CFR part 63.2) and provide that new
source standards apply when construction or reconstruction of an
affected source occurs.
The affected source for this proposed rule is broadly defined to
include all operations associated with the removal of paint from a
substrate using MeCl and the spray application of coatings. These
operations include the use of MeCl-containing paint strippers by
immersion, brushing on, and/or spraying on to remove a coating to
change the color of the item or because the life of the coating has
been exceeded, or to remove paint for inspection purposes or during
repair; storage and mixing of coatings and other materials; surface
preparation; coating application and flash-off; drying and curing of
applied coatings; cleaning operations; and waste handling operations.
Each of the equipment items subject to regulation (e.g., containers
of paint or stripper, spray booths, spray guns, gun cleaners) is either
a relatively low cost item, or could be easily moved about inside a
paint stripping and miscellaneous surface coating operation, hence, for
this proposal, a broad definition of affected source that encompasses
the entire paint stripping and miscellaneous surface coating operation
was selected. This approach would subject the entire operation to the
same compliance date. Had we proposed a narrow definition for an
affected source, replacement or purchase of a single item could cause
that item to be considered a new source, resulting in different
compliance dates and additional reporting. Furthermore, for the most
part, new and existing affected sources are subject to the same
emission standards, so the same environmental benefit will be realized
regardless of whether the source is considered new or existing.
Defining the affected source narrowly could result in
[[Page 52966]]
a paint stripping or miscellaneous surface coating operation having
several affected sources that could be subject to different compliance
dates, but the same standards, imposing additional burdens on the
source without any environmental benefit.
C. How did we determine the basis and level of the proposed standards
for new and existing sources?
As previously stated above, CAA section 112(d)(5) authorizes EPA to
establish emission standards for area sources that provide for the use
of generally available control technologies or management practices
that reduce emissions of HAP (GACT). Determining what constitutes GACT
involves considering the control technologies and management practices
that are generally available to the area sources in the source
category. We also consider the standards applicable to major sources in
the same industrial sector to determine if the control technologies and
management practices are transferable and generally available to area
sources. In appropriate circumstances, we may also consider
technologies and practices at area and major sources in similar
categories to determine whether such technologies and practices could
be considered generally available for the area source category at
issue. Finally, as noted above, in determining GACT for a particular
area source category, we consider the costs and economic impacts of
available control technologies and management practices on that
category.
We began the rule development process by identifying other
standards developed for these specific processes. As discussed in
section II.E., above, we evaluated the emission control technology at
major sources for the types of operations found in these area source
categories to determine whether or not they were reasonable, feasible,
and cost-effective for the area sources. Based on the findings of the
major source NESHAP data gathering, the technology considered to be
appropriate for the target HAP, and the availability of the technology,
we considered whether or not these same emission controls were
technically feasible and generally available for the area source
categories.
Next, we met with industry associations and discussed their current
processes and the feasibility of adopting the emission control
technology specified as appropriate for the major sources. We learned
that, in fact, similar technology (i.e., spray booths, painter
training, HVLP guns, enclosed gun cleaners, and management practices to
reduce HAP usage) were already being employed at many of the area
sources. Therefore, it was determined that, given the availability and
cost-effectiveness of these emission control technologies, they
represent GACT for the targeted HAP from each source category (i.e.,
paint stripping, autobody refinishing, and plastic parts surface
coating). As previously stated, the target HAP emissions for which
these source categories were listed are MeCl from paint stripping
operations and cadmium, chromium, lead, manganese and nickel compounds
from the coatings operations. The resulting proposed GACT standards are
a combination of technology and management practices that control the
target HAP, and have a co-benefit of reducing other associated
emissions \1\ from these operations. The co-benefit is realized due to
the fact that the same technology applied to control the target HAP
emissions are also the best techniques for reducing some other
emissions associated with these operations.
---------------------------------------------------------------------------
\1\ The baseline emissions from the surface coating operations
are estimated to be about 38,000 tpy of HAP, including 12.4 tpy of
inorganic HAP (e.g.; Pb and Cr-VI compounds), 123,500 tpy of
criteria pollutants including 3,100 tpy of particulate matter (PM)
from paint overspray and 120,400 tpy of volatile organic compounds
(VOC) from coating and solvent evaporation.
---------------------------------------------------------------------------
In the development of these proposed emission standards, EPA
visited numerous paint stripping and coating operations, collected data
from various databases, and compiled information received during
previous data collection activities. We also met with facility owners
and other representatives of these industries. These site visits, data
review and contacts with industry provided the technical basis for the
proposed standards and are included in the public docket for this
rulemaking.
Paint Stripping
MeCl is the most common solvent and the target HAP for this source
category. Since MeCl is the target HAP, our analysis in determining
GACT began with understanding alternative stripping technologies and
best management practices to minimize MeCl emissions at existing major
and area sources. In selecting GACT for affected area sources that
perform paint stripping operations, we determined that best management
practices to minimize evaporative losses (fugitive emissions) from MeCl
in paint stripper formulations was not only a practice that many in the
industry use, but also was generally cost effective for all sources in
this category.
As part of the GACT analysis, we considered whether there were
differences in processes, sizes, or other factors affecting emissions,
control technologies or management practices that would warrant
subcategorization. Under CAA section 112(d)(1) of the CAA, EPA ``may
distinguish among classes, types, and sizes within a source category or
subcategory in establishing such standard.'' In looking to other means
by which MeCl emissions could be reduced from these operations, we did
recognize that some sources utilized alternative stripping technologies
(e.g., blasting) to accomplish much of their work. These sources,
distinguishable from the rest of the category by having other available
on site methods to strip paint not involving MeCl, could reasonably
route work away from paint stripping operations that involved MeCl as a
means of control. Pursuant to section 112(d)(1), we have subcategorized
these sources with alternative stripping methods by class. As mentioned
earlier, these different paint stripping methods include (1) non-MeCl--
containing chemical strippers; (2) mechanical stripping; (3) blasting
(including dry or wet media); and (4) thermal or cryogenic
decomposition. We also recognized that this subcategory represented the
30 percent (approximately) of the source category with the highest MeCl
emissions. We determined that sources that used 150 gallons or more per
year of paint stripper containing MeCl was the best approximation
criteria for defining this subcategory for three reasons.
First, based on our findings from: (1) A study of paint stripping
facilities (referenced in a Metropolitan Water District of Southern
California (Environmental Defense Fund) document entitled ``Source
Reduction and Recycling of Halogenated Solvents in Paint Stripping--
Technical Support Document''), (2) our understanding of the affected
facilities, and (3) our analysis of the model plants, for facilities
using 150 gallons of MeCl or more per year, we believe it is reasonable
to expect cost savings from the process of routing work away from paint
stripping operations involving MeCl to other means of stripping. The
study of paint stripping facilities highlighted to us that a good
portion of paint stripping at these facilities (as high as 90 percent
at one facility) was not really necessary. In being conservative, we
believe that 5 percent of paint stripping is not necessary. An example
of paint stripping that may be found as not necessary includes the
[[Page 52967]]
refinishing of personal oxygen gas cylinder surfaces (that often
automatically get stripped of paint for cosmetic purposes during
recycling) when they actually need no refinishing for serviceability.
In addition, we believe that there is a slight cost savings associated
with routing work away from paint stripping involving MeCl to a media
blasting technique, when the media involved is recycled. Second, our
analysis of model plants suggested that most facilities using 150
gallons of MeCl or more per year had other methods of stripping
available on site (e.g., blasting or thermal) to which work could be
easily routed. Finally, we recognized that the 150 gallon threshold
reasonably coincides with exposure levels at which Occupational Safety
and Health Administration (OSHA) requirements (29 CFR 1910.123-
1910.126) are to be implemented. OSHA provided specific dip tank size
criteria to characterize which size tanks must follow specific worker
safety requirements. We calculated, based on the sizes provided by
OSHA, the volume of stripper that the minimum tank would hold and used
this volume for our size criteria. For these reasons we are proposing
that facilities using 150 gallons of MeCl or more per year must, in
addition to the best management practices to minimize evaporative
losses, develop and implement the MeCl minimization plan mentioned
earlier.
We recognize that given the wide range of paint stripping
operations and techniques, there is no single substitute that could
completely eliminate the need for MeCl-containing paint strippers,
particularly on confined and hard to reach surfaces where other methods
tend not to remove paint as well. We do, however, believe that given
the existing management practices currently exercised by much of this
industry, it is not unreasonable to incorporate management practices
that minimize or eliminate MeCl emissions from many of the applications
where MeCl-containing paint strippers are used. Therefore, we are
proposing standards that require operators to employ management
practices to reduce the emissions of MeCl through alternative paint
stripping techniques when possible, and, for sources that use 150
gallons of MeCl or more per year to develop and implement a
minimization plan to reduce MeCl-containing paint stripper use when it
is not needed.
Miscellaneous Surface Coating
The emissions from these operations come primarily from the spray
application of coatings. Although most of the HAP are deposited as part
of the paint film, some of the HAP becomes airborne in the paint
overspray. The volume of coating deposited as part of the paint film as
a fraction of the volume of paint sprayed is referred to as the
transfer efficiency (i.e., 60 percent of the coating sprayed is
deposited as paint film then the transfer efficiency is 60 percent).
Our analysis of operations that involve the spray application of
coatings has determined that GACT for these coating operations is a
combination of: (1) Confining all spray coating operations to a spray
booth or equivalent ventilated and filtered enclosure, (2) using only
spray equipment that is designed to achieve a high rate of transfer
efficiency (HVLP or equivalent spray technology), and (3) having the
spray equipment operator trained and certified in the techniques needed
to properly set up and operate high transfer efficiency spray equipment
in order to optimize the transfer efficiency.
Based on the site visits, data review, and contacts with industry,
for which documentation is provided in the public docket for this
rulemaking, we have determined that the standard practice among the
majority of facilities in the miscellaneous surface coating industry is
to perform nearly all spray painting inside a spray booth or ventilated
prep station enclosed by curtains. The only exceptions are priming
small areas, or performing spot repairs with an air brush. At many
facilities, all spray painting is performed in a spray booth or
ventilated prep station to reduce contaminants that would compromise
the final finish and to maintain a clean work area. In addition, it is
standard practice to filter the exhaust from the booth or prep station
to capture paint overspray so that it is not deposited on ventilation
equipment or surrounding property. Therefore, based on the availability
and cost-effectiveness, we have determined that a filtered spray booth
or prep station is GACT for all miscellaneous surface coating
operations to control HAP emissions. The proposed standards would
require all spray painting that is not done with an airbrush or hand-
held non-refillable aerosol cans to be done in a filtered spray booth
or prep station. We also conclude that the above proposed control
requirements can be achieved without additional burden to affected
sources because filtered spray booths or prep stations are already
required in order to comply with OSHA standards for spray finishing
operations (29 CFR 1910.94(c)).
At the majority of facilities that were visited, the spray booths
were fitted with either fiberglass or polyester fiber filters on the
spray booth and prep station exhaust. One facility had a water-wash
spray booth filter and another had expanded polystyrene foam baffle
filters. An EPA study entitled ``Comparative Study of Spray Booth
Filter System Efficiency'', which is provided in the public docket for
this rulemaking, determined that fiberglass and polyester fiber filters
had superior performance, relative to other filter types, such as
polystyrene foam and cardboard baffle filters, in controlling the heavy
metals found in paint overspray and which are the target HAP for these
source categories. Therefore, based on our findings during the site
visits, information provided by the industry on the most commonly used
filters, and the EPA study on filter effectiveness and the cost-
effectiveness we have determined that these fiberglass and polyester
fiber filters represent GACT for controlling the heavy metals present
in paint overspray.
The proposed rule would allow for the use of other types of paint
overspray filters, but they would be required to achieve 98-percent
filter efficiency. This alternative was included since the EPA did not
test all types of filters used in spray booths; therefore the market
may already provide for filters that are as equally efficient which
were not available or not tested in the EPA study, but nevertheless
representative of GACT. The EPA study on filter effectiveness and
filter efficiency data provided by filter vendors formed the basis for
the 98-percent filter efficiency The limit represents a performance
level that separates the fiberglass and polyester fiber filters from
baffle type filters. The baffle type filters were shown in the EPA
study to have poor performance in controlling fine particulate that can
contain heavy metals.
The proposed standards would not prohibit the use of coatings that
contain the heavy metals or target HAP for these source categories.
Although California has prohibited the use of automotive refinish
coatings that contain Cr-VI and cadmium (Cd), a nationwide prohibition
would impose unreasonable burden on the industry, and could force
facilities out of business due to a lack of alternative materials that
could address the performance criteria (e.g., corrosion protection)
that may be used in all environments across the United States. The
proposed standards would specifically require spray equipment that is
designed to achieve a high rate of transfer efficiency (HVLP or
equivalent spray technology) in order to reduce the overall amount of
coating
[[Page 52968]]
required to complete each coating job. Reducing the amount of coating
required for each job directly correlates to significant reductions in
the overall emissions from these coating operations. Conventional high-
pressure air-atomized spray guns have a typical transfer efficiency of
about 30 percent. That means that for every gallon of coating sprayed,
only 0.30 gallon reaches the part being coated. The remaining 0.70
gallon misses the part and either lands on the booth walls and floor or
is pulled into the spray booth filters and exhaust system. To get one
gallon on the part, a conventional spray gun needs to use 3\1/3\
gallons of coating. HVLP and other types of high-efficiency spray guns
use lower air pressures and achieve transfer efficiencies of about 50
percent, or greater, with appropriate operator training. To get one
gallon on the part, a high efficiency spray gun needs to use only 2
gallons of coating. This increased transfer efficiency represents a 40
percent decrease in coating consumption and in resultant emissions
compared to conventional spray guns. For these reasons, many surface
coating operations have already switched to HVLP and other types of
high efficiency spray guns.
All of the autobody refinishing facilities visited by EPA and about
80 percent of the other miscellaneous surface coating facilities for
which EPA has data used HVLP or equivalent spray guns for coating
application. About half these sources were not required to do so by
regulations and have switched in order to reduce coating costs through
reduced consumption. Regulations for autobody refinishing in 10 States
require the use of HVLP spray guns or their equivalent statewide, and
they are required in ozone non-attainment areas in 12 States without a
statewide requirement. Given the cost-effectiveness and the use of HVLP
or equivalent spray guns has been adopted at the facilities visited by
EPA and is required in many States and ozone non-attainment areas, we
have determined that these types of spray guns are GACT for spray-
applied coatings.
The purpose of requiring the spray equipment operator to be trained
and certified is to ensure that the operator is skilled in the
techniques needed to achieve a high rate of transfer efficiency. We
have concluded, based on the findings of the Spray Technique Analysis
and Research (STAR[supreg]) program study presented in the following
paragraph, and included in the public docket for this rulemaking, that
even when spray operations are confined within a spray booth and
appropriate spray technology is used, they are not as effective if the
painter is not properly trained. We therefore have determined that GACT
requires implementation of the above requirements by a trained painter.
The training would include measures intended to increase transfer
efficiency and reduce overspray and coating usage. Most, if not all of
the measures are currently offered in training provided by coating
manufacturers on an annual basis. In addition to manufacturer-sponsored
training, the STAR[supreg] program, which originated at the University
of Northern Iowa Waste Reduction Center, has now been adopted at 37
locations (primarily community colleges) throughout the United States.
Coating manufacturers currently provide this training to their clients
as part of the service benefits of contracting with them and as a
component in the warranty agreement. Data from the STAR[supreg] program
demonstrate that spray operator training can increase transfer
efficiency for those using high efficiency spray equipment from an
average of about 50 percent to 60 percent, or more, representing a 20
percent reduction in coating usage compared to untrained operators.
This 20 percent reduction in coating usage would translate into a 20
percent reduction in emissions of organic HAP that are contained in
those coatings. It would also reduce emissions of the heavy metals that
are in the coatings.
It is important to note that these ``untrained'' operators are not
inexperienced painters. They often have many years of experience before
they enter these training programs. However, they have not been
specifically trained in how to best set up and operate high efficiency
spray equipment and to optimize their technique to maximize transfer
efficiency and minimize coating consumption.
About 3,500 painters have already completed STAR[supreg] training
and at least one company operating multiple collision repair shops has
established a STAR[supreg]-based in-house training program. Since many
painters already attend regular training sponsored by coating companies
and trade organizations, we determined that the specified painter
training, or a comparable training program, is GACT for these source
categories.
Our analysis has determined that the proper training and
certification for spray coating operators should be comparable to
existing programs such as those offered by The Inter-Industry
Conference on Auto Collision Repair (I-CAR) and the STAR[supreg]-based
programs offered in various states. The essential elements of training
and certification, for the purposes of achieving compliance with the
requirements of the proposed standard, should at a minimum, train,
examine and certify each spray equipment operator in the proper
techniques in: (1) Coating material handling, including spills and
clean up, (2) substrate preparations that minimize over spray, (3)
proper equipment selection and set-up to optimize transfer efficiency,
(4) coating application and spray technique that minimizes over spray,
(5) spray equipment cleaning and maintenance, and (6) operating and
maintaining a spray booth.
However, EPA does not believe that I-CAR and STAR[supreg] are the
only programs that contain these essential elements for operator
instruction and certification in the skills needed to achieve a high
rate of transfer efficiency with proper equipment. The proposed rule
does not limit training and certification to only these two programs,
since the critical elements are the training components. We are open to
and request comment regarding viable training and certification
alternatives that are available to spray coating operators that should
be considered that would achieve the same or comparable results. These
alternatives could include, but not be limited to, state, community
college, or industry sponsored training and certification programs,
either on the job or through classroom, hands-on, or on-line
instruction.
The proposed rule would require that all spray gun cleaning be done
in enclosed spray gun cleaners, or the disassembled spray gun could be
cleaned by hand without the benefit of atomization. Spraying of
cleaning solvent through spray guns outside of an enclosed gun washer
would be prohibited. All of the facilities visited by EPA had enclosed
gun washers and other contacts with industry members indicate that this
is standard practice among well-controlled facilities. Therefore, we
have determined that an enclosed spray gun cleaner or hand cleaning is
GACT for these source categories to reduce emissions from spray gun
cleaning. We believe the measures in the proposed rule would
effectively control emissions of the target HAP for these sources
categories.
D. How did we select the format of the proposed standards?
The proposed standards are in the form of management practice
standards and equipment standards. These include reducing the need for
MeCl-containing paint strippers, painter training and the use of
filtered booths or prep stations, HVLP spray guns, and
[[Page 52969]]
enclosed spray gun cleaners. This format was selected since these
standards are the most universally applicable and effective for these
source categories, they reflect the types of controls that are already
in place at well-controlled facilities, and they would have the minimum
burden for monitoring, recordkeeping, and reporting compared to other
formats. Facilities applying coatings can use filters other than the
specified types if the filters are demonstrated to achieve 98 percent
filter efficiency. They may also use spray guns other than HVLP spray
guns if the manufacturer has demonstrated to the EPA that they are
equivalent in transfer efficiency.
The proposed standards do not include numerical emission limits.
After considerable review of industry-supplied data for paint stripping
and coatings, and consultation with the industry, we have determined
that numerical emission limits are not feasible given the variability
in the operational parameters (e.g., substrate (i.e., metal, plastic or
wood), performance specifications, production rate, etc.) and the
variety of work being performed, as many of the sources in these source
categories are job shops. Given this variability for these sources EPA
believes it is important to provide the greatest flexibility for these
sources without compromising emission reductions.
E. How did we select the initial compliance and testing requirements?
The proposed rule includes the minimum requirements needed to
demonstrate initial compliance. You would demonstrate initial
compliance by implementing all of the requirements in the proposed rule
by the dates specified in the rule, and certifying in the initial
compliance notification that your source is in compliance.
This proposed rule is comprised of management practices and
equipment requirements, of which sources have the option of
substituting the specified equipment with alternative equipment that
would achieve equivalent or better emissions reductions than that
specified, provided they obtain approval from the Administrator as
required in section 63.11173(e) of the proposed rule. However, test
methods are needed in order to demonstrate equivalent performance of
alternative equipment. For this reason, the proposed rule includes
separate testing methods that would need to be followed to measure
paint overspray filter efficiency when a source does not use fiberglass
or polyester fiber filters, and to demonstrate that a paint spray gun
is equivalent to an HVLP spray gun in transfer efficiency. The proposed
methods represent those methods that are already in use to measure
filter efficiency and equivalency to HVLP spray guns based on transfer
efficiency. It is expected that the filter or spray gun supplier would
complete these measurements and provide copies of the results to the
purchaser so they could document compliance. We do not expect the owner
of the surface coating operation to perform the measurements.
F. How did we select the continuous compliance requirements?
The proposed rule includes the minimum requirements needed to
demonstrate continuous compliance. You would demonstrate continuous
compliance by ensuring that you follow the prescribed best management
practices for paint stripping operations. Further, if you use more than
150 gal per year of paint stripper containing MeCl, you must
demonstrate compliance by implementing and following your MeCl
Minimization Plan. For surface coating operations you would ensure that
all painters maintain their training and certification, all spray-
applied coating is done in a filtered spray booth or prep station, the
filters are of the proper type or efficiency, all spray guns are HVLP
or equivalent, and all gun cleaning is done in an enclosed spray gun
cleaner or by hand. You would also need to maintain records that all
painters are trained and certified, and that filters and spray guns
meet the specifications for filter efficiency and transfer efficiency,
respectively, if needed.
G. How did we select the compliance date?
You would be allowed 2 years to comply with the proposed standards
if your operation is an existing source. We believe that 2 years is
needed to allow adequate time for existing sources to ensure that all
additional equipment, if needed, is purchased and installed and to
provide sufficient time for painters employed by the 36,000 sources to
receive the training that would be required by the proposed rule.
H. How did we decide to exempt these area source categories from the
CAA title V permit requirements?
Section 502(a) of the CAA provides that the Administrator may
exempt an area source category from title V if he determines that
compliance with title V requirements is ``impracticable, infeasible, or
unnecessarily burdensome'' on an area source category. See CAA section
502(a). In December 2005, EPA interpreted the term ``unnecessarily
burdensome'' in CAA section 502 and developed a four-factor balancing
test for determining whether title V is unnecessarily burdensome for a
particular area source category, such that an exemption from title V is
appropriate. See 70 FR 75320, December 19, 2005 (``Exemption Rule'').
The four factors that EPA identified in the Exemption Rule for
determining whether title V is ``unnecessarily burdensome'' on a
particular area source category include: (1) Whether title V would
result in significant improvements to the compliance requirements,
including monitoring, recordkeeping, and reporting, that are proposed
for an area source category (see 70 FR 75323); (2) whether title V
permitting would impose significant burdens on the area source category
and whether the burdens would be aggravated by any difficulty the
sources may have in obtaining assistance from permitting agencies (see
70 FR 75324); (3) whether the costs of title V permitting for the area
source category would be justified, taking into consideration any
potential gains in compliance likely to occur for such sources (see 70
FR 75325); and (4) whether there are implementation and enforcement
programs in place that are sufficient to assure compliance with the
NESHAP for the area source category, without relying on title V permits
(see 70 FR 75326).
In discussing the above factors in the Exemption Rule, we explained
that we considered on ``a case-by-case basis the extent to which one or
more of the four factors supported title V exemptions for a given
source category, and then we assessed whether considered together those
factors demonstrated that compliance with title V requirements would be
`unnecessarily burdensome' on the category, consistent with section
502(a) of the Act.'' See 70 FR 75323. Thus, in the Exemption Rule, we
explained that not all of the four factors must weigh in favor of
exemption for EPA to determine that title V is unnecessarily burdensome
for a particular area source category. Instead, the factors are to be
considered in combination and EPA determines whether the factors, taken
together, support an exemption from title V for a particular source
category.
In the Exemption Rule, in addition to determining whether
compliance with title V requirements would be unnecessarily burdensome
on an area source category, we considered, consistent with the guidance
provided by the legislative history of section 502(a), whether
exempting the area
[[Page 52970]]
source category would adversely affect public health, welfare or the
environment. See 70 FR 15254-15255, March 25, 2005. As discussed below,
we have determined that the exemptions from title V would not adversely
affect public health, welfare and the environment.
In considering the exemption from title V requirements for sources
in the categories affected by this proposed rule, we first compared the
title V monitoring, recordkeeping, and reporting requirements (factor
one) to the requirements in this proposal and determined that the
management practices currently used at most facilities is GACT and the
rule requires recordkeeping that serves as monitoring and deviation
reporting to ensure compliance. Because the proposal would require
management practices for certain processes and requires recordkeeping
designed to serve as monitoring and that recordkeeping assures
compliance with the requirements of the proposed rule, additional
monitoring requirements that might be added under title V would be
unnecessary to assure compliance. Monitoring other than recordkeeping
is not practical or appropriate in either case because the requirements
are management practices. Records are required to ensure that the
management practices are followed, including such records as the amount
of MeCl use in paint stripping or the training certification for spray
gun operators.
As part of the first factor, we also considered the extent to which
title V could potentially enhance compliance for area sources covered
by this proposed rule through recordkeeping or reporting requirements.
For any affected area source facility, the proposed rule would require
an initial notification, a compliance status report, and report of
deviations. We considered the various title V recordkeeping and
reporting requirements, including requirements for a 6-month monitoring
report, deviation reports, and an annual certification in 40 CFR 70.6
and 71.6.
The proposed rule would also require affected facilities to certify
compliance with the management practices identified as GACT. In
addition, facilities must maintain records showing compliance with the
required management practices and deviations. The information required
in the deviation reports and records is similar to the information that
must be provided in the deviation reports required under 40 CFR
70.6(a)(3) and 40 CFR 71.6(a)(3). We acknowledge that title V might
impose additional compliance requirements on this category, but, we
conclude that the monitoring, recordkeeping and reporting requirements
of this proposed rule are sufficient to ensure compliance with the
proposed standards, and title V would not significantly improve those
compliance requirements.
Under the second factor, we determine whether title V permitting
would impose a significant burden on the area sources in these
categories and whether that burden would be aggravated by any
difficulty the source may have in obtaining assistance from the
permitting agency. Subjecting any source to title V permitting imposes
certain burdens and costs that do not exist outside of the title V
program. The EPA estimated that the average cost of obtaining and
complying with a title V permit was $38,500 per source for a 5-year
permit period, including fees. See Information Collection Request for
Part 70 Operating Permit Regulations, January 2000, EPA ICR Number
1587.05. While EPA does not have specific information for the burdens
and costs of permitting for either paint stripping or miscellaneous
surface coating area sources; there are inherent activities associated
with the part 70 and 71 rules that are mandatory and impose burdens on
every affected source. These activities include: Reading and
understanding permit program guidance and regulations; obtaining and
understanding permit application forms; answering follow-up questions
from permitting authorities after the application is submitted;
reviewing and understanding the permit; collecting records; preparing
and submitting monitoring reports on a 6-month or more frequent basis;
preparing and submitting prompt deviation reports, as defined by the
State, which may include a combination of written, verbal, and other
communications methods; collecting information, preparing, and
submitting the annual compliance certification; preparing applications
for permit revisions every 5 years; and, as needed, preparing and
submitting applications for permit revisions. In addition, although not
required by the permit rules, many sources obtain the contractual
services of professional scientists and engineers (consultants) to help
them understand and meet the permitting program's requirements. The ICR
for part 70 provides additional information on the overall burdens and
costs, as well as the relative burdens of each activity described here.
For a more comprehensive list of requirements imposed on part 70
sources (and hence, burden on sources), see the requirements of 40 CFR
70.3, 70.5, 70.6, and 70.7.
In assessing the second factor for facilities affected by this
proposal, we found that nearly all of approximately 3,000 paint
stripping and 36,000 miscellaneous surface coating facilities are small
businesses, some having as few as one or two employees. These small
sources lack the technical resources needed to independently comply
with permitting requirements and the financial resources needed to hire
the necessary staff or outside consultants. Given that title V
permitting would impose significant economic and non-economic costs on
nearly all of these area sources, we conclude that title V is a
significant burden for sources in these categories. Furthermore, given
the large number of sources in these categories and relative small
facility size, it would likely be difficult for each to obtain
independent assistance from their respective permitting authorities.
We, thus, conclude that factor two strongly supports title V exemptions
for facilities in these area source categories.
The third factor, which is closely related to the second factor, is
whether the costs of title V permitting for these area sources would be
justified, taking into consideration any potential gains in compliance
likely to occur for such sources. We explained under the second factor
(above) that the economic and non-economic costs of compliance with
title V would impose a significant burden on nearly all of the
approximately 3,000 paint stripping and 36,000 miscellaneous surface
coating facilities. We also concluded in considering the first factor
that, while title V might impose additional requirements, that the
monitoring, recordkeeping and reporting requirements in the NESHAP
assure compliance with the management practices imposed in the NESHAP.
In addition, below in our consideration of the fourth factor we find
that there are adequate implementation and enforcement programs in
place to assure compliance with the NESHAP. Because the costs, both
economic and non-economic, of compliance with title V are high, and the
potential for gains in compliance are low, title V permitting is not
justified for this source category. Accordingly, the third factor
supports title V exemptions for these area source categories.
Finally, in determining if title V requirements were unnecessarily
burdensome, we considered whether there are implementation and
enforcement programs in place that are sufficient to assure compliance
with the
[[Page 52971]]
NESHAP without relying on title V permits (factor four). In doing so,
we considered whether there are sufficient State programs in place to
enforce these proposed area source standards, and we believe that there
are sufficient State programs to assure compliance with these proposed
area source standards. In addition, we recognize that EPA retains
authority to enforce these NESHAP anytime under CAA sections 112, 113
and 114. We concluded that title V permitting is ``unnecessary'' to
assure compliance with these proposed standards because the statutory
requirements for implementation and enforcement of these proposed
standards by the delegated States and EPA are sufficient to assure
compliance, in all parts of the United States, without title V permits.
States and EPA often conduct voluntary compliance assistance, outreach,
and education programs (compliance assistance programs), which are not
required by statute. We determined that these additional programs will
supplement and enhance the success of compliance with these proposed
standards and conclude that, in light of all of the above, there are
implementation and enforcement programs in place that are sufficient to
assure compliance with these proposed standards without relying on
title V permitting.
In applying the fourth factor in the Exemption Rule, where EPA had
deferred action on the title V exemption for several years, we had
enforcement data available to demonstrate that States were not only
enforcing the provisions of the area source standards that we exempted,
but that the States were also providing compliance assistance to ensure
that the area sources were in the best position to comply with the
standards. See 70 FR 75325-75326. In proposing this rule, we did not
have similar data available on the specific enforcement as in the
Exemption rule, but we have no reason to think that States will be less
diligent in enforcing these proposed standards. See 70 FR 75326. In
fact, States must have adequate programs to enforce the HAP regulations
and provide assurances that it will enforce all NESHAP, including area
source standards, before EPA will delegate the program. See 40 CFR part
63, subpart E.
In light of all of the above, we conclude that there are
implementation and enforcement programs in place that are sufficient to
assure compliance with these proposed standards without relying on
title V permitting.
Balancing the four factors for these area source categories
strongly supports that title V is unnecessarily burdensome. While title
V might add additional compliance requirements if imposed, we concluded
that there would not be significant improvements to the compliance
requirements in this proposed rule, because the proposed rule
requirements are specifically designed to assure compliance with the
management and equipment practices imposed on these area source
categories. We also concluded that the economic and non-economic costs
of compliance with title V, in conjunction with the likely difficulty
this large number of small sources would have obtaining assistance from
the permitting authority, would impose a significant burden on these
area sources. We determined that the high relative costs would not be
justified given that there was likely to be little or no potential gain
in compliance likely to occur if title V were required, and that there
are adequate implementation and enforcement programs in place to assure
compliance with these proposed standards. Thus, we conclude that title
V permitting would be ``unnecessarily burdensome'' for these area
source categories.
In addition to evaluating whether compliance with title V
requirements is ``unnecessarily burdensome,'' EPA also considered,
consistent with guidance provided by the legislative history of section
502(a), whether exempting these area source categories from title V
requirements would adversely affect public health, welfare, or the
environment. Exemption of these area source categories from title V
requirements would not adversely affect public health, welfare, or the
environment because the level of control would remain the same if a
permit were required. The title V permit program does not impose new
substantive air quality control requirements on sources, but instead
requires that certain procedural measures be followed, particularly
with respect to determining compliance with applicable requirements. As
stated in our consideration of factor one for these categories, title V
would not lead to significant improvements in the compliance
requirements applicable to existing or new area sources.
Furthermore, one of the primary purposes of the title V permitting
program is to clarify, in a single document, the various and sometimes
complex regulations that apply to sources in order to improve
understanding of these requirements and to help sources to achieve
compliance with the requirements. In these cases, however, placing all
requirements for the source in a title V permit would do little to
clarify the requirements applicable to each source or assist it in
compliance with the proposed rule requirements, because of the
simplicity of the source and the proposed standards, and the likelihood
that these sources are not subject to other regulatory requirements
under the CAA. We have no reason to think that new sources would be
substantially different from the existing sources in these categories.
In addition, we explained in the Exemption Rule that requiring permits
for the large number of area sources could, at least in the first few
years of implementation, potentially adversely affect public health,
welfare, or the environment by shifting State agency resources away
from assuring compliance for major sources with existing permits to
issuing new permits for these area sources, potentially reducing
overall air program effectiveness. For this proposed rule, we conclude
that title V exemptions for these area sources will not adversely
affect public health, welfare, or the environment for all of the
reasons explained above.
For the foregoing reasons, we are proposing to exempt these source
categories from title V permitting requirements.
V. Impacts of the Proposed Standards
The EPA estimates that about 39,000 establishments perform paint
stripping and miscellaneous surface coating operations. We estimate
that about 3,000 of these establishments are paint stripping facilities
and 36,000 establishments are surface coating operations. The majority
of these surface coating establishments (about 35,000) are involved in
motor vehicle and mobile equipment refinishing, and employ about
263,000 people, of which about one-third are painters.
A. What are the air impacts?
Paint Stripping Operations
The baseline MeCl emissions from paint stripping operations are
estimated to be 3,800 tpy. Around 500 tpy is estimated to be emitted
from the approximately 2,000 facilities that use less than 150 gal of
paint stripper containing MeCl, per year (which approximately equals
MeCl emissions of 1,000 pounds per year based on typical stripper
formulations). The remaining 3,300 tpy is estimated to be emitted by
the approximately 1,000 paint strippers that use more than 150 gallons
of MeCl stripper and who would be required to develop a MeCl
minimization plan.
[[Page 52972]]
Miscellaneous Coating Operations
The baseline emissions from the surface coating operations are
estimated to be about 38,000 tpy of HAP, including 12.4 tpy of
inorganic HAP (e.g. Pb and Cr-VI compounds). In addition to the HAP,
baseline emissions of criteria pollutants are estimated to be 3,100 tpy
of particulate matter (PM) from paint overspray and 120,400 tpy of
volatile organic compounds (VOC) from coating and solvent evaporation.
Implementation of the proposed standards would achieve a reduction
of 6,900 tpy of HAP from surface coating operations, including about
11.4 tpy of inorganic HAP. In addition to the HAP, we estimate PM
reductions of about 2,900 tpy and VOC reductions of about 20,900 tpy.
These reductions would occur as a result of reduced use of HAP-
containing solvents and coatings, increased use of filtered spray
booths to capture overspray, increased spray painter training and use
of HVLP or equivalent guns to improve transfer efficiency and to reduce
coating overspray and paint consumption, and increased use of enclosed
spray gun washers. Additional detail on these calculations are included
in the public docket for this rulemaking.
B. What are the cost impacts?
Paint Stripping Operations
We estimate that the proposed standards for paint stripping
operations will result in an initial cost of around $1,500,000 and a
net savings in annual costs. This includes an estimated initial cost of
$490,000 and annual costs of $80,000 for the nearly 2,000 paint
strippers whose annual usage of paint stripper containing MeCl is below
150 gallons. Initial costs for the approximately 1,000 paint strippers
who use more than 150 gallons per year, who would be required to
develop MeCl minimization plans are estimated to be just over $1
million. The annual costs for those plants are estimated to be a net
savings of $920,000.
For the nearly 2,000 paint strippers whose annual usage of MeCl in
paint strippers is below 1,000 lb, or whose annual usage of paint
stripper containing MeCl is below 150 gallons, evaluation of improved
methods to reduce the emissions of MeCl from evaporative losses
comprise most of the costs.
The costs for the approximately 1,000 paint strippers who are
required to develop MeCl minimization plans are attributable to the
development and implementation of the MeCl minimization plan. Annual
costs will include an estimated $400,000 for the development and
implementation of the MeCl minimization plan and reporting requirements
and an estimated $450,000 associated with switching paint stripping
technologies. Annual savings resulting from the implementation of the
MeCl minimization plan include an estimated $420,000 from the
elimination of unnecessary stripping operations and $1,320,000 in
management practice savings from the reduced use of MeCl-containing
strippers. For reasons set out earlier in this preamble, we believe
that 5 percent of paint stripping in the private sector is not
necessary and specifically request comment as to whether or not 5
percent is an appropriate figure to use. Additional detail on these
calculations are included in the public docket for this rulemaking.
Miscellaneous Coating Operations
We estimate that the proposed standards for surface coating
operations will have no net annual cost to surface coating operations.
The initial cost of complying with the proposed standards would be off-
set and recovered over time by cost savings as a result of more
efficient use of labor and materials by surface coating operations. The
initial costs for surface coating operations are for purchase improved
spray booth filters, automated enclosed gun washers, HVLP spray guns,
and painter training, if needed to comply with the proposed standards.
Spray finishing operations are already required by OSHA standards
to perform spray painting in a spray booth or similar enclosure.
However, the proposed standards specify that certain types of filters
have to be used on the spray booth exhaust to minimize HAP emissions,
and these filters are not addressed by OSHA standards. Some surface
coating sources may need to replace their current filters for ones with
higher paint overspray capture efficiency, but the higher efficiency
filters are readily available and will not result in an additional
cost.
We estimate that about 5,000 facilities would need to purchase and
install an enclosed spray gun washer. The total capital cost for each
source that would need to install a gun washer was estimated to be
approximately $1,800. This cost is the same for new and existing
sources. The total capital cost for all 5,000 sources that would be
required to purchase a spray gun washer was estimated to be $9.0
million.
The EPA estimates that sources that would need to purchase a spray
gun washer would have no net annualized capital costs or operating
costs. We estimate the annual costs would be offset from reduced labor
to clean spray guns and reduced costs for cleaning solvent purchase and
disposal. Spray gun washers are automated so that after loading the
spray gun in the washer, the painters can perform other tasks while the
spray guns are being cleaned. Automated spray gun washers are also
capable of re-using solvent for gun cleaning to minimize solvent
consumption and waste disposal. Finally, small surface coating
facilities that do not currently have an automated gun washer can still
comply with the proposed standards by cleaning guns by hand as long as
they do not atomize cleaning solvent from the gun and they collect
spent solvent in a container that is closed when not in use.
The estimated cost for training is $1,000 per painter, which covers
tuition cost and labor cost for 16 hours of training time. Based on the
United States census data collected to estimate new sources for this
source category the number of refinishing shops in the United States
remain constant (i.e., for every new shop, a shop closes) and it is
expected that this trend will continue in the future. This reflects on
the number of new painters that would need training. We assumed that
training certification would be valid for 5 years, so about one-fifth
of painters (20 percent) would receive training every year. We estimate
that about 18,000 painters would be trained per year at an annual cost
of $18 million per year.
However, EPA believes that these training costs could be over-
stated for at least two reasons. First, many facilities already send
their painters to training sponsored by paint companies and trade
organizations. Paint companies sponsor painter training so that the
paint company can reduce warranty claims on their paint products. These
training courses already cover much of the same material required by
the proposed rule. Therefore, the rule would not impose new training
costs on these facilities that already participate in training.
Second, the estimated training cost could be offset by reduced
coating costs if the training results in reduced coating consumption.
Data from the STAR[supreg] training programs indicate that painters who
complete this training can decrease the amount of coating sprayed by
about 20 percent per job. We estimate that if a typical facility
reduced their coating consumption and costs by about 4 percent per
year, the cost savings would equalize the increased cost of training
after one year, and there would be no net cost in training. To recover
the cost of training over 5 years, a typical facility would need to
reduce their coating consumption by slightly less than 1 percent. As
previously mentioned, EPA
[[Page 52973]]
believes the costs associated with training are over-stated; however,
we specifically request comment on whether or not these assumptions are
accurate.
In summary, EPA estimates that the proposed requirements for
surface coating operations would not result in any net increase in
annual costs from the control requirements for surface coating
operations. We estimated that the annual cost for recordkeeping and
reporting for surface coating operations would be $7.8 million for
about 36,000 surface coating operations, or an average of about $220
per facility. Cost estimates are based on the information available to
the Administrator and presented in the economic analysis of this rule.
Additional detail is included in the public docket for this rulemaking.
C. What are the economic impacts?
The economic impact analysis focuses on changes in market prices
and output levels. A more detailed discussion of the economic impacts
is presented in the economic impact analysis memorandum that is
included in the docket.
Both the magnitude of control 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 prices and quantities will change
in response to the rule. In this case, we have so many facilities that
model facilities must be used in the cost analysis. The cost analysis
estimates that there will be no net increase in annual costs from the
control requirements from the proposed regulation for surface coating
operations. The record keeping and reporting costs are estimated to
range from $76 to $95 per facility per year.
These costs are too small to have any significant market impact.
Whether the costs are absorbed by the affected facilities or passed on
to the purchaser in the form of higher prices, the impacts would be
quite small.
The cost analysis estimates that there will be a net cost savings
from the control requirements, recordkeeping, and reporting from the
proposed regulation for paint stripping for all but the smallest model
plant. The cost for the smallest model plant is estimated to be $11 a
year.
Again, these costs are too small to have any significant market
impact. Whether the costs are absorbed by the affected facilities or
passed on to the purchaser in the form of higher prices, the impacts
would be quite small.
While most of these facilities are small, the very small costs are
not expected to be even a tenth of a percent of revenues. Thus a
significant impact is not expected for a substantial number of small
entities.
D. What are the non-air health, environmental, and energy impacts?
Paint Stripping Operations
We estimate that there will be a reduction in non-air health and
environmental impacts resulting from the paint stripping area source
NESHAP. Reduced usage of MeCl-containing chemical strippers will result
in reduction in waste water generated from rinsing chemically stripped
pieces. Additionally, reduced chemical stripping activity will result
in a reduction in the generation of hazardous wastes composed of rags
and other chemical stripper applicators and removal equipment.
EPA expects some increase in the need for energy to resulting from
switching away from MeCl-containing chemical strippers to other paint
stripping methods. There would be a slight increase in energy usage
associated with switching to other chemical strippers that do not
contain MeCl because they often need to be heated above room
temperature to be most effective. There is also some increase in energy
usage associated with non-manual mechanical stripping and blasting with
both dry and wet media.
The energy usage increase would be somewhat more for thermal
decomposition or cryogenic paint stripping technologies. Thermal
decomposition basically uses natural gas heated ovens to bake the paint
off the substrate. Cryogenic paint stripping methods have increased
electricity demands associated with the production of liquid nitrogen
or liquid carbon dioxide.
Miscellaneous Coating Operations
We estimated that about 5,000 surface coating operations would need
to install spray booths to comply with the proposed standards. Spray
booths would need electricity to run fans and natural gas to heat make-
up air to maintain facility temperatures in colder weather. We estimate
that this would lead to an increased electricity consumption of 9.8
million kilowatt hours per year and increased natural gas consumption
of 724 million cubic feet per year. However, spray booths are already
required for spray finishing operations to comply with OSHA standards,
so theses impacts would not be assigned to these proposed standards.
Facilities that install spray booths would also need to dispose of
used spray booth filters. These are often placed in a sealed drum to
prevent spontaneous combustion and disposed of as hazardous waste. We
estimate that 5,000 new spray booths could generate used filters equal
to about 8,000 drums per year.
Facilities that install enclosed spray gun washers would need to
dispose of spent solvent as hazardous waste that formerly may have been
allowed to evaporate. However, we cannot estimate this amount because
we cannot determine the baseline disposal practices for facilities that
did not have enclosed spray gun washers. If facilities previously
handled spent solvent waste as hazardous waste, the installation of an
enclosed spray gun washer could lead to a more efficient use of
cleaning solvent and could reduce the volume of waste generated.
We expect no increase in generation of wastewater or other water
quality impacts. None of the control measures considered for this rule
generates a wastewater stream.
The installation of spray booths and enclosed gun washers, and
increased worker training in the proper use and handling of coating
materials should reduce worker exposure to harmful chemicals in the
workplace. This should have a positive benefit on worker health, but
this benefit cannot be quantified in the scope of this rulemaking.
VI. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning And Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is a ``significant regulatory action.'' Accordingly, EPA
submitted this action to the Office of Management and Budget (OMB) for
review under Executive Order 12866 and any changes made in response to
OMB recommendations have been documented in the docket for this action.
B. Paperwork Reduction Act
The information collection requirements in this proposed rule have
been submitted for approval to the OMB under the Paperwork Reduction
Act, 44 U.S.C. 3501 et seq. The Information Collection Request (ICR)
document prepared by EPA has been assigned EPA ICR number 2268.01.
The information collection requirements are based on notification,
recordkeeping, and reporting requirements in the NESHAP General
Provisions (40 CFR part 63, subpart A), which are mandatory for all
operators subject to national emission standards. These recordkeeping
and reporting
[[Page 52974]]
requirements are specifically authorized by CAA section 114 (42 U.S.C.
7414). All information submitted to EPA pursuant to the recordkeeping
and reporting requirements for which a claim of confidentiality is made
is safeguarded according to Agency policies set forth in 40 CFR part 2,
subpart B.
The proposed standards would require sources to submit an initial
notification that they are subject to the standards, submit a
notification of whether or not the source is in compliance (the
notification of compliance status), submit annual compliance reports,
and keep records needed to demonstrate compliance. These requirements
would be the minimum needed to ensure that sources were complying with
the requirements of the proposed rule.
We estimate that about 40,000 existing area sources would be
subject to the proposed standards. We estimate that about 1,600 new
facilities would open per year in the 3 years following promulgation of
the standards, but that the total number of facilities would remain
constant as new facilities replace facilities that have closed.
New and existing sources would have no capital costs associated
with the information collection requirements in the proposed standards.
The estimated recordkeeping and reporting burden in the third year
after the effective date of the promulgated rule is estimated to be
62,877 labor hours at a cost of $2.2 million. This estimate includes,
depending on the type of source, the cost of keeping records of paint
stripping solvent consumption, painter training, spray booth filter
efficiency, and spray gun transfer efficiency, and the cost of
submitting annual compliance reports. The average hours and cost per
facility would be 6.4 hours and $219. Each facility would be required
to submit one compliance report per year. Starting in year 4, about
40,000 facilities would respond per year.
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.
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, including the use of automated collection
techniques, we have established a public docket for this rule, which
includes this ICR, under Docket ID number EPA-HQ-2005-0526. Submit any
comments related to the ICR for this proposed rule to EPA and OMB. See
ADDRESSES section at the beginning of this notice for where to submit
comments to EPA. Send comments to OMB at the Office of Information and
Regulatory Affairs, Office of Management and Budget, 725 17th Street,
NW, Washington, DC 20503, Attention: Desk Officer for EPA. Since OMB is
required to make a decision concerning the ICR between 30 and 60 days
after September 17, 2007, a comment to OMB is best assured of having
its full effect if OMB receives it by October 17, 2007. The final rule
will respond to any OMB or public comments on the information
collection requirements contained in this proposal.
C. Regulatory Flexibility Act
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 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 the proposed area
source NESHAP on small entities, small entity is defined as: (1) A
small business that meets the Small Business Administration size
standards for small businesses found at 13 CFR 121.201, which for the
entities affected by the proposed rule is generally one having less
than 500 to 1,000 employees, depending on the specific NAICS code under
which that business is classified, or annual revenues of less than $6.5
million, refer to NAICS code table listed previously; (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 the proposed rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. There would
not be adverse impacts on existing area sources in either of the three
source categories because the proposed rule does not create any new
burdens for existing sources, other than minimal notification and
reporting requirements, and best management or equipment practices,
which are designed to recover initial cost. We have determined that the
cost of these requirements (estimated at less than $1,000 per year per
facility) would not result in an adverse economic impact on any
facility, large or small (i.e., the cost is less than one percent of
total revenues, even for small businesses).
Although this proposed rule will not have a significant economic
impact on a substantial number of small entities, EPA nonetheless has
tried to reduce the impact of this rule on small entities. The proposed
standards represent practices and controls that are common throughout
the sources engaged in paint stripping and miscellaneous surface
coating. The proposed standards also require the minimal amount of
recordkeeping and reporting needed to demonstrate and verify
compliance. These proposed standards were also developed in
consultation with numerous individual small businesses and their
representative trade associations. We continue to be interested in the
potential impacts of the proposed rule on small entities and welcome
comments on issues related to such impacts.
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 an EPA rule for which a
[[Page 52975]]
written statement is needed, section 205 of the UMRA generally requires
EPA 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, based on discussions with State, local, and
tribal governments during site visits, that this rule does 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 one year. Thus, the proposed rule is not subject
to the requirements of sections 202 and 205 of the UMRA.
Some State, local, or tribal governments have paint stripping and/
or miscellaneous surface coating operations (e.g., municipal fleet
vehicle maintenance garages) that may be subject to the requirements of
this proposed rule. However, we do not believe that any of them are
operated by small government entities. Small government entities are
expected to contract for refinishing services when these services are
needed, rather than doing this work in-house. In addition, total
expenditures for all entities to comply with the proposed rule are
estimated to be less than $100 million in any year.
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.''
This proposed rule 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 EPA is required by CAA
section 112, to establish the standards in the proposed rule. The
proposed rule primarily affects private industry, and does not impose
significant economic costs on State or local governments. The proposed
rule does not include an express provision preempting State or local
regulations. Thus, the requirements of section 6 of the Executive Order
do not apply to the proposed rule. Thus, Executive Order 13132 does not
apply to this rule.
