National Emissions Standards for Hazardous Air Pollutants:
Reinforced Plastic Composites Production
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule; amendments.
-----------------------------------------------------------------------
SUMMARY: The EPA is taking direct final action on amendments to the
national emissions standards for hazardous air pollutants (NESHAP) for
reinforced plastic composites production which were issued April 12,
2003, under section 112 of the Clean Air Act (CAA). The direct final
amendments revise compliance options for open molding, correct errors,
and add clarification to sections of the rule. We are issuing the
amendments as a direct final rule, without prior proposal, because we
view the revisions as noncontroversial and anticipate no adverse
comments. However, in the Proposed Rules section of this Federal
Register notice, we are publishing a separate document that will serve
as the proposal to amend the NESHAP for reinforced plastic composites
production if adverse comments are filed.
DATES: The direct final rule is effective on October 24, 2005 without
further notice, unless EPA receives adverse written comment by
September 26, 2005 or if a public hearing is requested by September 6,
2005. If adverse comments are received, EPA will publish a timely
withdrawal in the Federal Register indicating which provisions will
become effective and which provisions are being withdrawn due to
adverse comment.

I. Background
The EPA promulgated NESHAP for reinforced plastic composites
production on April 21, 2003. The final rule (40 CFR part 63, subpart
WWWW) includes standards for hazardous air pollutants (HAP), as well as
monitoring, performance testing, recordkeeping, and reporting
requirements related to those standards. After promulgation of the
rule, EPA received numerous questions relating to rule interpretation.
The questions pointed out minor inconsistencies in some of the tables
and the rule language, areas where the rule requirements were not
clear, and restrictions that would preclude most facilities using the
least burdensome open molding compliance option. Today's action
includes direct final rule amendments that resolve inconsistencies,
clarify language, and add additional compliance flexibility. None of
the amendments will have any discernable effect on the stringency of
the rule.
II. Amendments to 40 CFR Part 63, Subpart WWWW
This subpart applies to facilities that manufacture reinforced
plastic composites and are located at major sources of hazardous air
pollutants. For more information on rule applicability see 40 CFR
63.5785.
The EPA received numerous questions relating to rule requirements
for polymer casting and closed molding operations. These operations
were mentioned in the rule or rule preamble so it would be clear that
they were covered by the rule. However, we did not list any
requirements for these operations in the rule, except for compression/
injection closed molding which has a work practice requirement. In
order to make it clear these operations have no requirements, polymer
casting and closed molding operations (except for compression/injection
molding) have been added to the list of operations with no requirements
in 40 CFR 63.5790(c). We also added language to that paragraph to
clarify that though certain operations have no requirements, any
requirements that apply to co-located operations are not affected.
A question was raised concerning area sources that commenced
construction prior to August 2, 2002, but did not become a major source
until after August 2, 2002. The final rule language in 40 CFR
63.5795(a)(2) appears to imply that any area source that became major
due to an expansion or other type of construction after August 2, 2002,
would be considered a new source because it was not an affected source
prior to commencing construction. Our intent was that any existing
source would not become a new source as the result of reconstruction.
Therefore, we are changing the sentence ``You commence construction,
and no other reinforced plastic composites production affected source
exists at that site'' by removing the word affected from the sentence.
The new language will now read ``You commence construction, and no
other reinforced plastic composites production source exists at that
site.'' Therefore, it will
[[Page 50120]]
now be clear that an area source that existed prior to August 3, 2002
will not be considered a new source once it becomes major due to an
expansion or other type of reconstruction.
In 40 CFR 63.5799, the first sentence of paragraph (a) refers to
paragraphs (b) and (d) of 40 CFR 63.5805. Paragraph (b) of 40 CFR
63.5805 discusses existing source requirements. We should have
referenced paragraph (c) of 40 CFR 63.5805, which discusses
requirements for new facilities. We have changed the rule text to
correct this.
Also in 40 CFR 63.5799(b), we included a sentence that stated ``If
an existing facility has accepted an enforceable permit limit of less
than 100 tons per year of HAP, and can demonstrate that they will
operate at that level subsequent to the compliance date, then they can
be deemed to be below the 100 tons per year (tpy) threshold.'' We
received a comment that this sentence implies that a facility that used
process controls could not use a permit limit of 100 tons per year
(tpy) to demonstrate they were below the 100 tpy threshold. Our intent
was that any facility that could demonstrate, through its permit
requirements, that it would be below the 100 tpy threshold would not
have to perform emission calculations. Therefore, we have changed the
sentence to read ``If an existing facility has accepted an enforceable
permit limit that would result in emissions of less than 100 tpy of HAP
measured prior to any add-on controls, and can demonstrate that they
will operate at that level subsequent to the compliance date, they can
be deemed to be below the 100 tpy threshold.'' This should make it
clear that both restricted operation hours and use of process controls
are acceptable methods to demonstrate through permit requirements that
the facility will not meet nor exceed the 100 tpy threshold.
We received numerous questions concerning 40 CFR 63.5805,
specifically concerning when the 95 percent control requirement applied
to existing sources, and which operations were potentially subject to
95 percent control. We have revised the wording of 40 CFR 63.5805 to
make it more clear by changing paragraphs (a) and (b). Paragraph 40 CFR
63.5805(a) now discusses only the limits applicable to centrifugal
casting and continuous lamination/casting operations, rather that all
operations at existing sources. Paragraph 40 CFR 63.5805(b) discusses
all operations at existing sources not covered in paragraph 40 CFR
63.5805(a). No requirements have changed as result of this revision.
We received several questions relating to the values for the
highest organic HAP content for compliant materials shown in Table 3 to
subpart WWWW of part 63. In one case, a local regulatory agency wanted
to write the organic HAP limits in Table 3 to subpart WWWW as absolute
permit limits. In another case, someone interpreted the organic HAP
limits as absolute limits not to be exceeded.
The purpose of the highest organic HAP content for compliant
materials shown in Table 3 to subpart WWWW was only to provide examples
of compliant materials, and these values are not emission limits or HAP
content limits. The actual emission limits are the pounds per ton (lb/
ton) limits in the third column of Table 3 to subpart WWWW. If you meet
the lb/ton limits in the third column of Table 3 to subpart WWWW, you
are in compliance, regardless of the HAP content of the resin or gel
coat.
In order to clarify our intent, we have removed the fourth column
from Table 3 to subpart WWWW and reorganized the discussion of
compliance options in 40 CFR 63.5810. Paragraph (a) of 40 CFR 63.5810
now covers how to determine if a specific resin or gel coat, as
applied, meets its applicable emission limit. Paragraph (b) of 40 CFR
63.5810 covers averaging within each individual combination of
operation type and resin application method or gel coat type. Paragraph
(c) of 40 CFR 63.5810 covers demonstrating compliance using a weighted
average emission limit. Paragraph (d) of 40 CFR 63.5810 covers options
where you can meet the organic HAP emissions limit for one resin
application method and use the same resin for all application methods
of that resin type.
After promulgation, it was pointed out to EPA that for a facility
to be able to use the compliant materials compliance option, all
materials would have to be compliant. Therefore, even if a facility
used numerous resin and gel coats, having one noncompliant material
would require all materials be included in some type of averaging. This
would not result in any additional emissions reductions, but would
increase the amount of reporting and recordkeeping.
A second comment concerned the use of the term ``compliant
materials.'' It was pointed out that it is the combination of a
specific resin or gel coat, the application method, and controls that
determine compliance, not the resin or gel coat alone. For example, a
38 percent HAP resin applied with nonatomized spray has an emission
factor that is below its corresponding emission limit and, therefore,
would comply with its applicable emission limit. However, if the same
resin is applied manually, its emission factor would be above its
corresponding emission limit, and to comply with the rule, this
combination of resin and application method would have to be averaged
with other operations. This specific resin, as applied, complies in one
case, but not the other. Therefore, using the term compliant materials
is misleading.
For this reason, we have modified 40 CFR 63.5810 to clarify that
when a specific resin or gel coat, as applied, meets the applicable
emission limit, then it is in compliance, and we have dropped the term
compliant materials from the rule. We are also modifying the rule to
allow facilities to both demonstrate compliance for some resins and gel
coats using averaging, and that some individual resins and gel coats,
as applied, comply with their emission limits. This change will have no
impact on the actual rule limits and should result in no change in HAP
emissions, but may reduce the required reporting and recordkeeping. We
have also revised paragraph (d) of 40 CFR 63.5895, which discusses
collecting data to demonstrate continuous compliance, to reflect this
change in compliance options. We are limiting this flexibility for a
specific resin or gel coat to state that if a specific resin or gel
coat is being used in any averaging calculations, then all of that
specific resin or gel coat resin must be part of averaging, even if the
resin, as applied, would meet its applicable emission limit. You must
collect resin use data for any resin or gel coat that is involved in
averaging.
In paragraph (a) of 40 CFR 63.5810, we state that you may
demonstrate compliance for an individual resin or gel coat based on the
HAP content, application method, and any controls that reduce its
emission factor. As an example, a non-corrosion resistant/high strength
(non-CR/HS) resin with an organic HAP content of 38 percent, applied
using nonatomized spray, would have an emission factor of 86 lb/ton
calculated using Equation 1.c.i of table 1 to subpart WWWW of part 63.
The emission limit for this operation as shown in table 3 to subpart
WWWW of part 63 is 88 lb/ton. Therefore, this resin, as applied,
complies with its emission limit. If the facility switches to atomized
resin application, the emission factor would change to 183 lb/ton, and
the resin would not comply with its emission limit.
A second example of demonstrating compliance for an individual
resin or
[[Page 50121]]
gel coat would be a 41 percent HAP resin that contains a vapor
suppressant with a vapor suppressant effectiveness factor of 0.5
applied using nonatomized spray. The emission factor calculated using
Equation 1.c.i from table 1 to subpart WWWW of part 63 would be 74.2
lb/ton. This is below the emission limit of 88 lb/ton. Therefore, this
resin, as applied complies with its emission limit as long as
nonatomized mechanical application and vapor suppressant continue to be
used.
If a facility required to meet the limits in table 3 to subpart
WWWW of part 63 has some type of add-on control, the control efficiency
may be used to show compliance. For example, a facility that uses a 35
percent HAP white gel coat with atomized spray has an emission factor
of 335.5 lb/ton, which is above the allowable emission limit of 267 lb/
ton. Therefore, this gel coat, as applied, does not comply with its
emission limit. However, if the facility controlled the gel coat spray
booth emissions by 47.5 percent overall (50 percent capture efficiency
and 95 percent control), the emission factor would now be 176 lb/ton,
and the gel coat does comply. This would require that the facility
demonstrate the capture and control efficiency using the appropriate
test methods in the NESHAP.
We have also added a paragraph (d)(4) to 40 CFR 63.5810 that states
if a facility elects to comply using the option in paragraph (d) of 40
CFR 63.5810 and uses resins that meet the organic HAP limits in table 7
to subpart WWWW of part 63, then those individual resins would be
considered to be in compliance, and resin use records are not required.
A commenter stated that some pultrusion machines have multiple
preform and pre-wet areas prior to the die. This configuration is
incompatible with the language of 40 CFR 63.5830(b)(4) because this
language would only be correct for one pre-wet area. Therefore, we have
revised the language so multiple preform and pre-wet areas can be used.
This change does not affect the total amount of area allowed to be open
and should not have any impact on control effectiveness.
A commenter stated that some direct die injection systems do not
recycle resin drip directly back to the resin injection chamber. It is
recycled back to the process. We agree that recycling the resin back to
the process would result in no additional emissions and have modified
the description of direct die injection in 40 CFR 63.5830(c)(3) to
reflect this.
Another commenter stated that they manufactured large pultruded
parts that currently do not meet the large parts definition of 1,000
reinforcements and a cross sectional area of 60 inches or more shown in
footnote 6 of table 3 to subpart WWWW of part 63. These parts were well
over 60 inches of cross sectional area but contain large roving and
stitched fabrics for reinforcement. They maintained that these parts
should be included in the large parts definition because the factors we
used to determine what made a part large, i.e., part size and
complexity, were as relevant here as they would be if they replaced the
fabric and larger roving with a smaller roving and more individual
reinforcements to meet the 1,000 reinforcement requirement.
We agree with this comment and have changed the definition of large
pultruded parts for existing pultrusion operations in footnote 6 to
table 3 of subpart WWWW of part 63 to 60 square inches or more and
1,000 reinforcements, or 60 square inches or more and the glass
equivalent of 1,000 ends of 113 yield roving. This change also includes
correcting the cross sectional measure to 60 square inches, not 60
inches. We also made corresponding changes to item 9 of table 9 to
subpart WWWW of part 63.
We received a comment that equation 2 in 40 CFR 63.5885 was in
error because, based on the definition of uncontrolled wet-out area
organic HAP emissions, the equation did not account for emissions that
are captured and vented to a control device. We agreed with this
comment and have revised equations 2 and 3 of 40 CFR 63.5885 to account
for all emissions generated in the wet-out areas.
A commenter noted that we did not specify how a source was to
report changing compliance options. We have added paragraph (i) to 40
CFR 63.5910 that requires the source to state if they changed
compliance options in their next compliance report.
We made several corrections to the definitions in 40 CFR 63.5935 in
response to comments. In the definition for ``high performance gel
coat,'' we had listed the National Science Foundation as a source of
property testing standards. This should have been the National
Sanitation Foundation. We changed the definition of ``mixing'' to
include mixing of putties or polyputties. In the definition for ``neat
resin plus,'' we had left the word ``plus'' out of the last sentence.
In the definition of ``polymer casting,'' a commenter noted that
sometimes polymer casters vibrate or smooth the material. We added
language to the ``polymer casting'' definition to make it clear that
vibrating or smoothing the resin is not considered rolling out or
working the resin.
We made several changes to table 1 to subpart WWWW of part 63. We
corrected a typographical error in the column numbering. We also
corrected equation 1.f where we had an error on the first term of the
equation and added a new equation to calculate emissions from atomized
spray gel coat using robotic or automated spray. Finally, we added a
footnote to table 1 to subpart WWWW of part 63 stating that the
equations presented are intended for use to determine compliance with
the rule and do not preclude the use of other emission factors to
calculate emissions for other purposes, such as reports required by
their title V permit. The reason for this change was an industry
concern that State and local regulators were requiring sources to use
the equations in table 1 to subpart WWWW of part 63 in lieu of
potentially more accurate factors. However, this footnote does not
preclude a facility from using the equations in table 1 to subpart WWWW
of part 63 if these equations are deemed to be the most accurate
available.
Several changes were made to table 3 to subpart WWWW of part 63
based on comments and questions received after promulgation of the
final rule. We received a comment that for three of the operations in
table 1 to subpart WWWW of part 63, substituting the value for the
highest HAP content for a compliant resin in column four into the
equations in table 1 to subpart WWWW of part 63 resulted in a
calculated emission factor that was above the corresponding emission
limit. This should not happen if the resin or gel coat is considered
compliant. On further review, we discovered that the error was due to
the way we rounded the calculations during floor development. As a
result, the facilities that set the floor for these three operations
would not be in compliance. We do not believe that the rounding
procedure should result in a floor-setting facility to now be out of
compliance with the floor. Therefore, we changed the rounding technique
used to calculate the emission limits for the open molding operations
in table 3 to subpart WWWW of part 63. The result was the emission
limits for the three operations noted by the commenter changed
slightly. The limit for open molding, CR/HS resins, mechanical resin
application changed from 112 to 113 lb/ton. The emission limit for non-
CR/HS resin, mechanical resin changed from 87 to 88 lb/ton. The
emission limit for open molding, tooling gel coat changed from 437 to
440 lb/ton. These changes will not affect the costs
[[Page 50122]]
of compliance or emissions reductions of the rule. The changes simply
make the floor emission limits consistent with the facilities setting
the floors. The changes in table 3 to subpart WWWW of part 63 also
slightly changed the calculated maximum HAP content for these processes
shown in table 7 to subpart WWWW of part 63, and we have updated table
7 to subpart WWWW of part 63 to reflect the changes in table 3 to
subpart WWWW of part 63.
One commenter stated that regulated sources were confused on which
emission limit to use for shrinkage controlled resins when the resin is
used to make tools. We added a footnote to clarify that a shrinkage
controlled resin is subject to the emission limits in item 5 of table 3
to subpart WWWW of part 63 regardless of whether it is used as a
tooling or a production resin.
In table 3 to subpart WWWW of part 63 we did not have emission
limits for manually applied gel coat because we did not have data to
develop specific limits. In the footnotes, we stated that for
compliance purposes, manually applied gel coat should be treated as if
it were applied using spray guns. In table 1 to subpart WWWW of part
63, we had an equation to calculate an emission factor for manual gel
coat application, but we stated not to use the equation for compliance
purposes. We believe this has caused some confusion. Therefore, we have
removed the manual gel coat equation from table 1 to subpart WWWW of
part 63 because this equation is not necessary to show compliance with
the NESHAP. We have also revised the footnote concerning manual gel
coat application in table 3 to subpart WWWW of part 63 to make it more
clear that to demonstrate compliance for manually applied gel coat you
treat manually applied gel coat as if it were applied using spray
equipment.
A commenter noted that footnote 1 should apply to items 6 and 7 of
table 4 to subpart WWWW of part 63, not just to item 8. We agree with
this comment and have revised table 4 to subpart WWWW of part 63
accordingly.
A commenter noted that table 7 to subpart WWWW of part 63 as
written implied that, for items 1.a and 4.a, it would be permissible to
use atomized mechanical application. This was not our intent. The
compliance options in table 7 were intended to provide additional
flexibility to regulated sources by allowing the use of the same resin
in different operations. The organic HAP limits based on mechanical
resin application were all determined using nonatomized spray.
Therefore, we have added a footnote to items 1.a and 4.a. of table 7 to
subpart WWWW of part 63 to state that nonatomized resin application is
required.
A commenter noted that the language in item 5.a.ii of table 8 to
subpart WWWW of part 63 implies that all pultrusion machines at
existing sources must reduce emissions by 60 weight percent, while the
language in 40 CFR 63.5830(e)(2) states that facilities may demonstrate
compliance if the weighted average reduction based on resin throughput
for all machines combined in 60 percent. We have revised item 5.a.ii of
table 8 to subpart WWWW of part 63 to make the language consistent with
40 CFR 63.5830(e)(2). We also changed 40 CFR 63.5830(e)(2) to correct a
spelling error.
We received several questions concerning the applicability of rule
requirements to filler putties used to fill gaps or smooth sharp
corners. We did not specifically investigate these materials in the
rulemaking. Putties are sometimes made on site using production resin,
but are also purchased as a separate product. We noted that the NESHAP
for Boat Manufacturing exempted putties, polyputties, and adhesives
from any requirements. Because we cannot say with certainty that filler
putties could meet the emission limits for manual resin application, we
are amending the rule to exclude putties, polyputties, and adhesives
from any emission limits. This will make the Reinforced Plastic
Composites Production NESHAP consistent with the Boat Manufacturing
NESHAP. However, any emissions from mixing of putties and polyputties
would be subject to the appropriate mixing emission limits or work
practices. We do not believe this will result in any change in the
stringency of the NESHAP for two reasons. First, most facilities use
very small amounts of putty compared to their use of resin and gel
coat. Second, the small amount of putty used will have a very small
surface area relative to the volume and be highly filled, which will
tend to result in less emissions than a comparable volume of resin or
gel coat.
We also have amended Sec. Sec. 63.5900, 63.5910, and 63.5915 of 40
CFR part 63 to parallel changes in other sections and incorporate
paragraph referencing changes.
III. Statutory and Executive Order Reviews
A. Executive Order 12866, Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the EPA
must determine whether this regulatory action is ``significant'' and,
therefore, subject to Office of Management and Budget (OMB) review and
the requirements of the Executive Order. The Executive Order defines
``significant regulatory action'' as one that is likely to result in a
rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or tribal governments or
communities;
(2) create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
It has been determined that this rule is not a ``significant
regulatory action'' under the terms of Executive Order 12866 and is,
therefore, not subject to OMB review.''
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
This action adds clarifications and corrections to the final standards.
However, the OMB has previously approved the information collection
requirements contained in the existing regulations (68 FR 36982, June
20, 2003) under the provisions of the Paperwork Reduction Act, 44
U.S.C. 3501, et seq. and has assigned OMB control number 2060-0509 (EPA
ICR No. 1976.02). A copy of the Information Collection Request (ICR)
may be obtained from Susan Auby by mail at the Office of Environmental
Information, Collection Strategies Division (2822), EPA, 1200
Pennsylvania Avenue, NW., Washington, DC 20460, by e-mail at
[email protected], or by calling (202) 566-1672. You also may download
a copy from the Internet at http://www.epa.gov/icr. Include the ICR
number in any correspondence.
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
[[Page 50123]]
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 are listed in 40 CFR part 9.
C. Regulatory Flexibility Analysis
EPA has determined that it is not necessary to prepare a regulatory
flexibility analysis in connection with the direct final rule
amendments.
For purposes of assessing the impacts of today's final rule on
small entities, small entity is defined as: (1) A small business as
defined by the Small Business Administrations' regulations at 13 CFR
121.201; (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 today's direct final rule
amendments on small entities, EPA has concluded that this action will
not have a significant economic impact on a substantial number of small
entities. We have determined that the direct final rule amendments will
not impose any new requirements on small entities. Today's action
includes direct final rule amendments that resolve inconsistencies,
clarify language, and add additional compliance flexibility. None of
the amendments will have any discernable effect on the stringency of
the rule.
D. Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for Federal agencies to assess the
effects of their regulatory actions on State, local, and tribal
governments and the private sector. Under section 202 of the UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, for proposed and final rules with ``Federal mandates'' that
may result in expenditures to State, local, and tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
1 year. Before promulgating a rule for which a written statement is
needed, section 205 of the UMRA generally requires us to identify and
consider a reasonable number of regulatory alternatives and adopt the
least costly, most cost-effective, or least burdensome alternative that
achieves the objectives of the rule. The provisions of section 205 do
not apply when they are inconsistent with applicable law. Moreover,
section 205 allows us 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.
The EPA has determined that the direct final rule amendments do not
contain a Federal mandate that may result in expenditures of $100
million or more for State, local, and tribal governments, in the
aggregate, or the private sector in any 1 year. The direct final rule
amendments apply only to affected sources in the reinforced plastic
composites industry and clarify and correct errors in the final rule
and, therefore, add no additional burden on sources. Thus, the direct
final rule amendments are not subject to the requirements of sections
202 and 205 of the UMRA.
E. Executive Order 13132, Federalism
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
The direct final rule amendments do not have federalism
implications. They will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132. No
reinforced plastic composites production facilities subject to the
direct final rule amendments are owned by State or local governments.
Therefore, State and local governments will not have any direct
compliance costs resulting from the direct final rule amendments.
Furthermore, the direct final rule amendments do not require these
governments to take on any new responsibilities. Thus, Executive Order
13132 does not apply to the direct final rule amendments.
F. Executive Order 13175, Consultation and Coordination With Indian
Tribal Governments
Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000),
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by tribal officials in the development of regulatory
policies that have tribal implications.'' The direct final rule
amendments do not have tribal implications as specified in Executive
Order 13175. They will not have substantial direct effects on tribal
governments, on the relationship between the Federal government and
Indian tribes, or on the distribution of power and responsibilities
between the Federal government and Indian tribes, because we are not
aware of any Indian tribal governments or communities affected by the
direct final rule amendments. Thus, Executive Order 13175 does not
apply to the direct final rule amendments.
The EPA specifically solicits additional comment on the direct
final rule amendments from tribal officials.
G. Executive Order 13045, Protection of Children From Environmental
Health Risks and Safety Risks
Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) Is determined to be ``economically significant'' as
defined under Executive Order 12866, and (2) concerns an environmental
health or safety risk that EPA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, the Agency must evaluate the environmental health or
safety effects of the planned rule on children, and explain why the
planned regulation is preferable to other potentially effective and
reasonably feasible alternatives
[[Page 50124]]
considered by the Agency. The EPA interprets Executive Order 13045 as
applying only to those regulatory actions that are based on health or
safety risks, such that the analysis required under section 5-501 of
the Executive Order has the potential to influence the regulation. The
direct final rule amendments are not subject to Executive Order 13045
because they are based on technology performance and not on health or
safety risks. They are also not considered ``economically significant''
as defined under Executive Order 12866.
H. Executive Order 13211, Actions That Significantly Affect Energy
Supply, Distribution, or Use
The direct final rule amendments are not subject to Executive Order
13211 (66 FR 28355, May 22, 2001) because they are not a significant
regulatory action under Executive Order 12866.
I. National Technology Transfer Advancement Act
Section 12(d) of the National Technology Transfer Advancement Act
(NTTAA) of 1995, Public Law 104-113, 12(d) (15 U.S.C. 272 note) directs
EPA to use voluntary consensus standards (VCS) in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. The VCS are technical standards (e.g., materials
specifications, test methods, sampling procedures, and business
practices) that are developed or adopted by VCS bodies. The NTTAA
directs EPA to provide Congress, through the OMB, explanations when the
Agency decides not to use available and applicable VCS.
The direct final rule amendments do not involve technical
standards. Therefore, EPA is not considering the use of any VCS.
J. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. The EPA will submit a report containing
the direct final rule amendments and other required information to the
United States Senate, the United States House of Representatives, and
the Comptroller General of the United States prior to publication of
the direct final rule amendments in the Federal Register. A major rule
cannot take effect until 60 days after it is published in the Federal
Register. The direct final rule amendments are not a ``major rule'' as
defined by 5 U.S.C. 804(2). The direct final rule amendments are
effective on October 24, 2005.

Sec. 63.5795 How do I know if my reinforced plastic composites
production facility is a new affected source or an existing affected
source?
(a) A reinforced plastic composites production facility is a new
affected source if it meets all the criteria in paragraphs (a)(1) and
(2) of this section.
(1) You commence construction of the source after August 2, 2001.
(2) You commence construction, and no other reinforced plastic
composites production source exists at that site.
(b) For the purposes of this subpart, an existing affected source
is any affected source that is not a new affected source.

0
a. Revising paragraph (a); and
0
b. Revising the paragraph (b) introductory text to read as follows:
Sec. 63.5799 How do I calculate my facility's organic HAP emissions
on a tpy basis for purposes of determining which paragraphs of Sec.
63.5805 apply?
* * * * *
(a) For new facilities prior to startup, calculate a weighted
average organic HAP emissions factor for the operations specified in
Sec. 63.5805(c) and (d) on a lbs/ton of resin and gel coat basis. Base
the weighted average on your projected operation for the 12 months
subsequent to facility startup. Multiply the weighted average organic
HAP emissions factor by projected resin use over the same period. You
may calculate your organic HAP emissions factor based on the factors in
Table 1 to this subpart, or you may use any HAP emissions factor
approved by us, such as factors from the ``Compilation of Air Pollutant
Emissions Factors, Volume I: Stationary Point and Area Sources (AP-
42),'' or organic HAP emissions test data from similar facilities.
(b) For existing facilities and new facilities after startup, you
may use the procedures in either paragraph (b)(1) or (2) of this
section. If the emission factors for an existing facility have changed
over the period of time prior to their initial compliance date due to
incorporation of pollution-prevention control techniques, existing
facilities may base the average emission factor on their operations as
they exist on the compliance date. If an existing facility has accepted
an enforceable permit limit that would result in less than 100 tpy of
HAP measured prior to any add-on controls, and can demonstrate that
they will operate at that level subsequent to the compliance date, they
can be deemed to be below the 100 tpy threshold.
* * * * *
0
5. Section 63.5805 is revised to read as follows:
Sec. 63.5805 What standards must I meet to comply with this subpart?
You must meet the requirements of paragraphs (a) through (h) of
this section
[[Page 50125]]
that apply to you. You may elect to comply using any options to meet
the standards described in Sec. Sec. 63.5810 through 63.5830. Use the
procedures in Sec. 63.5799 to determine if you meet or exceed the 100
tpy threshold.
(a) If you have an existing facility that has any centrifugal
casting or continuous casting/lamination operations, you must meet the
requirements of paragraph (a)(1) or (2) of this section:
(1) If the combination of all centrifugal casting and continuous
lamination/casting operations emit 100 tpy or more of HAP, you must
reduce the total organic HAP emissions from centrifugal casting and
continuous lamination/casting operations by at least 95 percent by
weight. As an alternative to meeting the 95 percent by weight
requirement, centrifugal casting operations may meet the applicable
organic HAP emissions limits in Table 5 to this subpart and continuous
lamination/casting operations may meet an organic HAP emissions limit
of 1.47 lbs/ton of neat resin plus and neat gel coat plus applied. For
centrifugal casting, the percent reduction requirement does not apply
to organic HAP emissions that occur during resin application onto an
open centrifugal casting mold using open molding application
techniques.
(2) If the combination of all centrifugal casting and continuous
lamination/casting operations emit less than 100 tpy of HAP, then
centrifugal casting and continuous lamination/casting operations must
meet the appropriate requirements in Table 3 to this subpart.
(b) All operations at existing facilities not listed in paragraph
(a) of this section must meet the organic HAP emissions limits in Table
3 to this subpart and the work practice standards in Table 4 to this
subpart that apply, regardless of the quantity of HAP emitted.
(c) If you have a new facility that emits less than 100 tpy of HAP
from the combination of all open molding, centrifugal casting,
continuous lamination/casting, pultrusion, SMC manufacturing, mixing,
and BMC manufacturing, you must meet the organic HAP emissions limits
in Table 3 to this subpart and the work practice standards in Table 4
to this subpart that apply to you.
(d)(1) Except as provided in paragraph (d)(2) of this section, if
you have a new facility that emits 100 tpy or more of HAP from the
combination of all open molding, centrifugal casting, continuous
lamination/casting, pultrusion, SMC manufacturing, mixing, and BMC
manufacturing, you must reduce the total organic HAP emissions from
these operations by at least 95 percent by weight and meet any
applicable work practice standards in Table 4 to this subpart that
apply to you. As an alternative to meeting 95 percent by weight, you
may meet the organic HAP emissions limits in Table 5 to this subpart.
If you have a continuous lamination/casting operation, that operation
may alternatively meet an organic HAP emissions limit of 1.47 lbs/ton
of neat resin plus and neat gel coat plus applied.
(2)(i) If your new facility manufactures large reinforced plastic
composites parts using open molding or pultrusion operations, the
specific open molding and pultrusion operations used to produce large
parts are not required to reduce HAP emissions by 95 weight percent,
but must meet the emission limits in Table 3 to this subpart.
(ii) A large open molding part is defined as a part that, when the
final finished part is enclosed in the smallest rectangular six-sided
box into which the part can fit, the total interior volume of the box
exceeds 250 cubic feet, or any interior sides of the box exceed 50
square feet.
(iii) A large pultruded part is a part that exceeds an outside
perimeter of 24 inches or has more than 350 reinforcements.
(e) If you have a new or existing facility subject to paragraph
(a)(2) or (c) of this section at its initial compliance date that
subsequently meets or exceeds the 100 tpy threshold in any calendar
year, you must notify your permitting authority in your compliance
report. You may at the same time request a one-time exemption from the
requirements of paragraph (a)(1) or (d) of this section in your
compliance report if you can demonstrate all of the following:
(1) The exceedance of the threshold was due to circumstances that
will not be repeated.
(2) The average annual organic HAP emissions from the potentially
affected operations for the last 3 years were below 100 tpy.
(3) Projected organic HAP emissions for the next calendar year are
below 100 tpy, based on projected resin and gel coat use and the HAP
emission factors calculated according to the procedures in Sec.
63.5799.
(f) If you apply for an exemption in paragraph (e) of this section
and subsequently exceed the HAP emission thresholds specified in
paragraph (a)(2) or (c) of this section over the next 12-month period,
you must notify the permitting authority in your semiannual report, the
exemption is removed, and your facility must comply with paragraph
(a)(1) or (d) of this section within 3 years from the time your organic
HAP emissions first exceeded the threshold.
(g) If you have repair operations subject to this subpart as
defined in Sec. 63.5785, these repair operations must meet the
requirements in Tables 3 and 4 to this subpart and are not required to
meet the 95 percent organic HAP emissions reduction requirements in
paragraph (a)(1) or (d) of this section.
(h) If you use an add-on control device to comply with this
subpart, you must meet all requirements contained in 40 CFR part 63,
subpart SS.
0
6. Section 63.5810 is revised to read as follows:
Sec. 63.5810 What are my options for meeting the standards for open
molding and centrifugal casting operations at new and existing sources?
You must use one of the following methods in paragraphs (a) through
(d) of this section to meet the standards for open molding or
centrifugal casting operations in Table 3 or 5 to this subpart. You may
use any control method that reduces organic HAP emissions, including
reducing resin and gel coat organic HAP content, changing to
nonatomized mechanical application, using covered curing techniques,
and routing part or all of your emissions to an add-on control. You may
use different compliance options for the different operations listed in
Table 3 or 5 to this subpart. The necessary calculations must be
completed within 30 days after the end of each month. You may switch
between the compliance options in paragraphs (a) through (d) of this
section. When you change to an option based on a 12-month rolling
average, you must base the average on the previous 12 months of data
calculated using the compliance option you are changing to, unless you
were previously using an option that did not require you to maintain
records of resin and gel coat use. In this case, you must immediately
begin collecting resin and gel coat use data and demonstrate compliance
12 months after changing options.
(a) Demonstrate that an individual resin or gel coat, as applied,
meets the applicable emission limit in Table 3 or 5 to this subpart.
(1) Calculate your actual organic HAP emissions factor for each
different process stream within each operation type. A process stream
is defined as each individual combination of resin or gel coat,
application technique, and control technique. Process streams within
operations types are considered different from each other if any of the
following four
[[Page 50126]]
characteristics vary: the neat resin plus or neat gel coat plus organic
HAP content, the gel coat type, the application technique, or the
control technique. You must calculate organic HAP emissions factors for
each different process stream by using the appropriate equations in
Table 1 to this subpart for open molding and for centrifugal casting,
or site-specific organic HAP emissions factors discussed in Sec.
63.5796. The emission factor calculation should include any and all
emission reduction techniques used including any add-on controls. If
you are using vapor suppressants to reduce HAP emissions, you must
determine the vapor suppressant effectiveness (VSE) by conducting
testing according to the procedures specified in appendix A to subpart
WWWW of 40 CFR part 63. If you are using an add-on control device to
reduce HAP emissions, you must determine the add-on control factor by
conducting capture and control efficiency testing using the procedures
specified in Sec. 63.5850. The organic HAP emissions factor calculated
from the equations in Table 1 to this subpart, or a site-specific
emissions factor, is multiplied by the add-on control factor to
calculate the organic HAP emissions factor after control. Use Equation
1 of this section to calculate the add-on control factor used in the
organic HAP emissions factor equations.
[GRAPHIC] [TIFF OMITTED] TR25AU05.013
Where:
Percent Control Efficiency=a value calculated from organic HAP
emissions test measurements made according to the requirements of
Sec. 63.5850 to this subpart.
(2) If the calculated emission factor is less than or equal to the
appropriate emission limit, you have demonstrated that this process
stream complies with the emission limit in Table 3 to this subpart. It
is not necessary that all your process streams, considered
individually, demonstrate compliance to use this option for some
process streams. However, for any individual resin or gel coat you use,
if any of the process streams that include that resin or gel coat are
to be used in any averaging calculations described in paragraphs (b)
through (d) of this section, then all process streams using that
individual resin or gel coat must be included in the averaging
calculations.
(b) Demonstrate that, on average, you meet the individual organic
HAP emissions limits for each combination of operation type and resin
application method or gel coat type. Demonstrate that on average you
meet the individual organic HAP emissions limits for each unique
combination of operation type and resin application method or gel coat
type shown in Table 3 to this subpart that applies to you.
(1)(i) Group the process streams described in paragraph (a) to this
section by operation type and resin application method or gel coat type
listed in Table 3 to this subpart and then calculate a weighted average
emission factor based on the amounts of each individual resin or gel
coat used for the last 12 months. To do this, sum the product of each
individual organic HAP emissions factor calculated in paragraph (a)(1)
of this section and the amount of neat resin plus and neat gel coat
plus usage that corresponds to the individual factors and divide the
numerator by the total amount of neat resin plus and neat gel coat plus
used in that operation type as shown in Equation 2 of this section.
[GRAPHIC] [TIFF OMITTED] TR25AU05.014
Where:
Actual Process Stream EFi=actual organic HAP emissions
factor for process stream i, lbs/ton;
Materiali=neat resin plus or neat gel coat plus used
during the last 12 calendar months for process stream i, tons;
n=number of process streams where you calculated an organic HAP
emissions factor.
(ii) You may, but are not required to, include process streams
where you have demonstrated compliance as described in paragraph (a) of
this section, subject to the limitations described in paragraph (a)(2)
of this section, and you are not required to and should not include
process streams for which you will demonstrate compliance using the
procedures in paragraph (d) of this section.
(2) Compare each organic HAP emissions factor calculated in
paragraph (b)(1) of this section with its corresponding organic HAP
emissions limit in Table 3 or 5 to this subpart. If all emissions
factors are equal to or less than their corresponding emission limits,
then you are in compliance.
(c) Demonstrate compliance with a weighted average emission limit.
Demonstrate each month that you meet each weighted average of the
organic HAP emissions limits in Table 3 or 5 to this subpart that apply
to you. When using this option, you must demonstrate compliance with
the weighted average organic HAP emissions limit for all your open
molding operations, and then separately demonstrate compliance with the
weighted average organic HAP emissions limit for all your centrifugal
casting operations. Open molding operations and centrifugal casting
operations may not be averaged with each other.
(1) Each month calculate the weighted average organic HAP emissions
limit for all open molding operations and the weighted average organic
HAP emissions limit for all centrifugal casting operations for your
facility for the last 12-month period to determine the organic HAP
emissions limit you must meet. To do this, multiply the individual
organic HAP emissions limits in Table 3 or 5 to this subpart for each
open molding (centrifugal casting) operation type by the amount of neat
resin plus or neat gel coat plus used in the last 12 months for each
open molding (centrifugal casting) operation type, sum these results,
and then divide this sum by the total amount of neat resin plus and
neat gel coat plus used in open molding (centrifugal casting) over the
last 12 months as shown in Equation 3 of this section.
[[Page 50127]]
[GRAPHIC] [TIFF OMITTED] TR25AU05.015
Where:
ELi=organic HAP emissions limit for operation type i,
lbs/ton from Tables 3 or 5 to this subpart;
Materiali=neat resin plus or neat gel coat plus used
during the last 12-month period for operation type i, tons;
n=number of operations.
(2) Each month calculate your weighted average organic HAP
emissions factor for open molding and centrifugal casting. To do this,
multiply your actual open molding (centrifugal casting) operation
organic HAP emissions factors calculated in paragraph (b)(1) of this
section and the amount of neat resin plus and neat gel coat plus used
in each open molding (centrifugal casting) operation type, sum the
results, and divide this sum by the total amount of neat resin plus and
neat gel coat plus used in open molding (centrifugal casting)
operations as shown in Equation 4 of this section.
[GRAPHIC] [TIFF OMITTED] TR25AU05.016
Where:
Actual Individual EFi=Actual organic HAP emissions factor
for operation type i, lbs/ton;
Materiali=neat resin plus or neat gel coat plus used
during the last 12 calendar months for operation type i, tons;
n=number of operations.
(3) Compare the values calculated in paragraphs (c)(1) and (2) of
this section. If each 12-month rolling average organic HAP emissions
factor is less than or equal to the corresponding 12-month rolling
average organic HAP emissions limit, then you are in compliance.
(d) Meet the organic HAP emissions limit for one application method
and use the same resin(s) for all application methods of that resin
type. This option is limited to resins of the same type. The resin
types for which this option may be used are noncorrosion-resistant,
corrosion-resistant and/or high strength, and tooling.
(1) For any combination of manual resin application, mechanical
resin application, filament application, or centrifugal casting, you
may elect to meet the organic HAP emissions limit for any one of these
application methods and use the same resin in all of the resin
application methods listed in this paragraph (d)(1). Table 7 to this
subpart presents the possible combinations based on a facility
selecting the application process that results in the highest allowable
organic HAP content resin. If the resin organic HAP content is below
the applicable value shown in Table 7 to this subpart, the resin is in
compliance.
(2) You may also use a weighted average organic HAP content for
each application method described in paragraph (d)(1) of this section.
Calculate the weighted average organic HAP content monthly. Use
Equation 2 in paragraph (b)(1) of this section except substitute
organic HAP content for organic HAP emissions factor. You are in
compliance if the weighted average organic HAP content based on the
last 12 months of resin use is less than or equal to the applicable
organic HAP contents in Table 7 to this subpart.
(3) You may simultaneously use the averaging provisions in
paragraph (b) or (c) of this section to demonstrate compliance for any
operations and/or resins you do not include in your compliance
demonstrations in paragraphs (d)(1) and (2) of this section. However,
any resins for which you claim compliance under the option in
paragraphs (d)(1) and (2) of this section may not be included in any of
the averaging calculations described in paragraph (b) or (c) of this
section.
(4) You do not have to keep records of resin use for any of the
individual resins where you demonstrate compliance under the option in
paragraph (d)(1) of this section unless you elect to include that resin
in the averaging calculations described in paragraph (d)(2) of this
section.

emissions reductions requirement?
* * * * *
(b) * * *
(4) For pultrusion lines with pre-wet area(s) prior to direct die
injection, no more than 12.5 inches of open wet stock is permitted
between the entrance of the first pre-wet area and the entrance to the
die. If the pre-wet stock has any drip, it must be enclosed.
* * * * *
(c) * * *
(3) Resin drip is captured in a closed system and recycled back to
the process.

(e) * * *
(2) The weighted average reduction based on resin throughput of all
machines combined is 60 percent. For purposes of the average percent
reduction calculation, wet area enclosures reduce organic HAP emissions
by 60 percent, and direct die injection and preform injection reduce
organic HAP emissions by 90 percent.

8. Section 63.5885 is revised to read as follows:
Sec. 63.5885 How do I calculate percent reduction to demonstrate
compliance for continuous lamination/casting operations?
You may calculate percent reduction using any of the methods in
paragraphs (a) through (d) of this section.
(a) Compliant line option. If all of your wet-out areas have PTE
that meet the requirements of EPA Method 204 of appendix M of 40 CFR
part 51, and all of your wet-out area organic HAP emissions and oven
organic HAP emissions are vented to an add-on control device, use
Equation 1 of this section to demonstrate compliance. In all other
situations, use Equation 2 of this section to demonstrate compliance.

9. Section 63.5895 is amended by revising paragraph (d) to read as
follows:
Sec. 63.5895 How do I monitor and collect data to demonstrate
continuous compliance?
* * * * *
(d) Resin and gel coat use records are not required for the
individual resins and gel coats that are demonstrated, as applied, to
meet their applicable emission as defined in Sec. 63.5810(a). However,
you must retain the records of resin and gel coat organic HAP content,
and you must include the list of these resins and gel coats and
identify their application methods in your semiannual compliance
reports. If after you have initially demonstrated that a specific
combination of an individual resin or gel coat, application method, and
controls meets its applicable emission limit, and the resin or gel coat
changes or the organic HAP content increases, or you change the
application method or controls, then you again must demonstrate that
the individual resin or gel coat meets its emission limit as specified
in paragraph (a) of Sec. 63.5810. If any of the previously mentioned
changes results in a situation where an individual resin or gel coat
now exceeds its applicable emission limit in Table 3 or 5 of this
subpart, you must begin collecting resin and gel coat use records and
calculate compliance using one of the averaging options on a 12-month
rolling average.

(2) Compliance with organic HAP emissions limits is demonstrated by
maintaining an organic HAP emissions factor value less than or equal to
the appropriate organic HAP emissions limit listed in Table 3 or 5 to
this subpart, on a 12-month rolling average, and/or by including in
each compliance report a statement that individual resins and gel
coats, as applied, meet the appropriate organic HAP emissions limits,
as discussed in Sec. 63.5895(d).
(3) Compliance with organic HAP content limits in Table 7 to this
subpart is demonstrated by maintaining an average organic HAP content
value less than or equal to the appropriate organic HAP contents listed
in Table 7 to this subpart, on a 12-month rolling average, and/or by
including in each compliance report a statement that resins and gel
coats individually meet the appropriate organic HAP content limits in

* * * * *
Mixing means the blending or agitation of any HAP-containing
materials in vessels that are 5.00 gallons (18.9 liters) or larger, and
includes the mixing of putties or polyputties. Mixing may involve the
blending of resin, gel coat, filler, reinforcement, pigments,
catalysts, monomers, and any other additives.
* * * * *
Neat resin plus means neat resin plus any organic HAP-containing
materials that are added to the resin by the supplier or the facility.
Neat resin plus does not include any added filler, reinforcements,
catalysts, or promoters. Neat resin plus does include any additions of
styrene or methyl methacrylate monomer in any form, including in
catalysts and promoters.
* * * * *
Polymer casting means a process for fabricating composites in which
composite materials are ejected from a casting machine or poured into
an open, partially open, or closed mold and cured. After the composite
materials are poured into the mold, they are not rolled out or worked
while the mold is open, except for smoothing the material and/or
vibrating the mold to remove bubbles. The composite materials may or
may not include reinforcements. Products produced by the polymer
casting process include cultured marble products and polymer concrete.

\1\ Organic HAP emissions limits for open molding and centrifugal
casting are expressed as lb/ton. You must be at or below these values
based on a 12-month rolling average.
\2\ This emission limit applies regardless of whether the shrinkage
controlled resin is used as a production resin or a tooling resin.
\3\ If you only apply gel coat with manual application, for compliance
purposes treat the gel coat as if it were applied using atomized spray
guns to determine both emission limits and emission factors. If you
use multiple application methods and any portion of a specific gel
coat is applied using nonatomized spray, you may use the nonatomized
spray gel coat equation to calculate an emission factor for the
manually applied portion of that gel coat. Otherwise, use the atomized
spray gel coat application equation to calculate emission factors.
\4\ For compliance purposes, calculate your emission factor using only
the appropriate centrifugal casting equation in item 2 of Table 1 to
this subpart, or a site specific emission factor for after the mold is
closed as discussed in Sec. 63.5796.
\5\ Calculate your emission factor using the appropriate open molding
covered cure emission factor in item 1 of Table 1 to this subpart, or
a site specific emission factor as discussed in Sec. 63.5796.
\6\ Pultrusion machines that produce parts that meet the following
criteria: 1,000 or more reinforcements or the glass equivalent of
1,000 ends of 113 yield roving or more; and have a cross sectional
area of 60 square inches or more are not subject to this requirement.
Their requirement is the work practice of air flow management which is
described in Table 4 to this subpart.
