GOALS AND OBJECTIVES
Ms. Strum began the meeting by reviewing the meeting agenda (see Attachment
1). This review was followed by a brief round of introductions. After
the introductions, Ms. Strum began by discussing EPA's main goals and
objectives for the meeting (see Attachment 2). Ms. Strum stated that EPA's
main goals and objectives for the meeting were to share information about
the progress of the proposed rule for the reinforced plastics industry,
and gather feedback from the attendees. Ms. Strum asked if the attendees
had any additional goals for the meeting. The attendees did not offer
any additional goals. After discussing the goals and objectives, Ms. Strum
continued with the briefing.
BRIEFING ON THE MACT RULE DEVELOPMENT AND THE REQUIREMENTS CURRENTLY
BEING CONSIDERED FOR PROPOSAL (See Attachment 3)
During the briefing, Ms. Strum covered the following items: legal requirements,
standards development, status of MACT development, EPA's approach for
developing MACT for existing open molding sources, and MACT standards
being considered for existing open molding sources.
Legal Requirements
Ms. Strum reviewed the legal issues and terms associated with the rule-making
process. Ms. Strum explained that maximum achievable control technology,
or "MACT," is the term commonly used to describe the standards mandated
by section 112 of the Clean Air Act (CAA). EPA is required by the CAA
to list categories of major sources of HAP and develop MACT standards
for these categories. Reinforced plastics production was one of the major
categories listed.
Standards Development
Ms. Strum explained the MACT floor represents the minimum level of stringency
mandated by the CAA. The MACT floor for existing sources is the average
of the best performing 12 percent of sources for a category or subcategory
of more than 30 sources, or the average of the best performing five sources
if there are less than 30 sources. The average can be the median or the
mean. Ms. Strum also indicated that subcategories can be based on classes,
types, or sizes of sources. For the Reinforced Plastics source category,
the average (within each subcategory) was taken to be the median facility
(sixth percentile).
Mr. Hood inquired if resins used during polymer casting could be averaged
with the gel coats applied by a facility that uses polymer casting. Ms.
Strum responded in the negative and indicated that facilities using polymer
casting could only average among the gel coats used. Ms. Strum stated
that because polymer casting is a separate subcategory from open molding
and that averaging is not allowed across subcategories, averaging between
polymer casting and gel coating is not allowed. Ms. Strum added that a
12-month rolling average option (for open molding) is being considered
to add flexibility.
Mr. Olsen asked for an explanation of the difference between "setting"
and "calculating" the MACT floor. Ms. Koman stated that the MACT floors
are calculated during the rule making process, and that the decisions
are set when the Federal Register proposal notice is signed by the Administrator.
Ms. Koman added that comments are taken after the proposal in the Federal
Register, and that changes may be made as a result of the comments. After
the comment period, the rule is promulgated in the Federal Register. Mr.
Olsen inquired as to when facilities must comply with the limits in the
rule. Ms. Koman stated that facilities are not required to comply with
the MACT standard until after the final rule is promulgated. Mr. Olsen
asked when the rule would be proposed. Ms. Strum replied the rule should
be proposed during November 1999. Ms. Elmore stated that the current MACT
floors represent the data that EPA has gathered through surveys and that
attendees are welcome to offer data that they feel might aid in the setting
of the MACT floors.
Open Molding Source Approach - Existing
Mr. Spaulding asked what EPA is considering for the definition of corrosion
resistance. Ms. Strum stated that the EPA has not developed a definition
at this time. Ms. Strum added that both the EPA and CFA have suggested
definitions to one another, but no definition has been acceptable at this
point.
Mr. Multanen asked about processes that are not listed, such as resin
pouring. Ms. Strum stated that pouring into an open mold would be considered
manual open molding. Mr. Multanen expressed concern that any definition
not explicitly worded in the rule could be misinterpreted by inspectors.
Ms. Elmore suggested putting concerns and suggestions into writing and
submitting them through the trade association. Ms. Elmore added that EPA
needs written documentation to properly take concerns into consideration.
Mr. Kensington stated that definitions written by people unfamiliar with
the industry may not be accurate, so the chance to give feedback about
the definitions would be beneficial. Mr. Colyer stated that EPA is concerned
about proper definitions as well, and that suggestions about clarifying
definitions would be helpful. Mr. Miles asked if the rule could be modified
or clarified after the final rule was promulgated. Mr. Colyer replied
that questions on applicability or interpretation are sent to EPA Regional
Offices first for a ruling and then to EPA Headquarters, if necessary.
Ms. Koman stated that some issues can be handled by published guidance
materials and others by technical rule revisions. Ms. Meyer indicated
that definitions can still be clarified after the rule is promulgated,
but changes are preferable before promulgation.
Mr. McNally expressed his strong concern regarding EPA's decision to
include adhesives in the Plastic Parts Surface Coatings MACT Standard
rather than the Reinforced Plastics MACT Standard. Mr. McNally continued
by stating that the removal of adhesives from the scope of the Reinforced
Plastics Composites MACT is problematic for the industry. Ms. Teal indicated
that the EPA group addressing the issue is still collecting data and has
not yet made a final decision on which MACT standard should address adhesives.
Several EPA representatives stated that information is being collected
and suggestions would be welcome. Mr. McNally indicated that no written
comments were necessary and the EPA should "just do it." Mr. Miles indicated
that this issue is an important one because adhesives are being used more
and more in the reinforced plastics industry. Ms. Strum asked how adhesives
are applied. Mr. Miles stated that the adhesives are applied using either
manual or mechanical resin application. Mr. Miles added that the more
effective adhesives generally contain methyl methacrylate. Ms. Elmore
suggested that one possible way to address adhesives is to create a separate
subcategory for adhesives in the same way that EPA has created a separate
subcategory for cleaning materials.
Mr. Holtzclaw indicated that most adhesives are resins in paste form
and inquired as to the difference between a resin paste and a resin. Mr.
Miles stated that one difference is that a resin paste is significantly
more viscous than a resin in liquid form. Mr. Hood expressed his concern
that there may be differences in the way that an inspector and a facility
define the difference between a resin and an adhesive which could lead
to compliance problems for the facility. Mr. Miles stated that it would
be undesirable for a facility to have to comply with another MACT standard
simply because the facility used adhesives. Mr. Hood stated that complying
with a separate MACT standard for adhesives would result in an inordinate
amount of extra work for a facility that only uses a couple of tubes of
adhesives a year.
Point Value System
Ms. Strum explained the point value system being considered for open
molding. Ms. Strum pointed out that the system is not a standard emission
limit or an emission factor. Ms. Strum explained that the goal of the
system is to reflect the overall effectiveness of control methods. Ms.
Strum continued by stating that averaging is allowed within the 10 open
molding process groupings and that an effectiveness test for vapor suppressed
resins is still being developed with the aid of CFA representatives.
Compliance Options
Ms. Strum stated that the options for compliance include lower HAP content
resins, non-atomized applications, add-on control devices, vapor suppressed
resins, and vacuum bagging. Mr. McNally asked Ms. Strum where she had
personally witnessed the vacuum bagging process. Ms. Strum indicated that
she had witnessed vacuum bagging at a boat manufacturing facility. Mr.
McNally asked if Ms. Strum had witnessed vacuum bagging at a facility
that is part of the Reinforced Plastics source category. Ms. Strum responded
in the negative but added that EPA representatives have called facilities
in the Reinforced Plastics source category to collect information about
the vacuum bagging process. Mr. McNally asked for an example of a product
created with vacuum bagging where the vacuum bag is applied immediately
after resin application. Mr. Miles provided an example of recreational
vehicle sidewall manufacturing where the vacuum bag is applied shortly
after resin application. Mr. McNally stated that he did not know of too
many applications where the bag is applied immediately after the resin
is applied to the mold. Mr. McNally continued by stating that usually
bleeder materials are applied first, then the bag. Mr. McNally indicated
that he would like to know exactly how the EPA is defining vacuum bagging.
Mr. Miles asked Ms. Strum if EPA's definition of vacuum bagging included
the placement of bleeder material prior to the application of the bag.
Ms. Strum responded in the affirmative.
Mr. Holtzclaw stated that vacuum bagging is a process, not a control
technology. Mr. Miles replied that vacuum bagging could be considered
a control technology because it does result in closing the mold after
the application of resin. Mr. McNally stated that vacuum bagging is done
for reasons other than reducing emissions. Mr. Miles stated that a facility
should receive credit for using vacuum bagging even if it was originally
intended for purposes other than emission control. Mr. McNally inquired
whether or not applying a vacuum was necessary to obtain credit. Ms. Proctor
indicated that the successful application of a vacuum would provide assurance
that a complete seal was achieved. Mr. Spaulding asked how a resin is
distributed with vacuum bagging and whether roll-out is allowed within
the EPA's definition of vacuum bagging. Ms. Strum indicated that the EPA
did not want to assign the same level of credit for vacuum bagging which
would be done after roll-out as vacuum bagging which would be done without
roll-out. Ms. Strum continued by stating that the 45% reduction credit
presently being assigned to vacuum bagging is for vacuum bagging without
roll-out. Mr. Holtzclaw stated that the application of a film to the mold
(after resin application and roll-out) may represent a potential control
technology missed by the EPA. Several attendees stated that they covered
the filament wound part with a bag after filament winding and stated that
this was an emission reduction technique that should be considered in
the point value system. Ms. Proctor asked how the EPA would assign an
emission reduction credit to such a control technology without any data.
Mr. Hood stated that since the applied film can block HAP emissions from
escaping, the credit assigned to such a control technique should be similar
to the credit assigned to vacuum bagging. Mr. Holtzclaw stated that the
emission reduction credit should be similar to vapor suppressed resins.
Mr. Schweitzer stated that he did not believe that any companies are
successfully using vapor suppressed resins in corrosion resistant applications
requiring secondary bonding. Mr. Schweitzer added that when making a corrosion
resistant product, secondary bonding problems often prohibit the usage
of vapor suppressed resins. Several attendees expressed concern that the
point values for the corrosion resistant subcategories are low enough
to force companies to use vapor suppressed resins to comply with the standard
which could cause secondary bonding problems. Ms. Proctor indicated that
facilities in the corrosion groupings do not have to use VSR and that
there are no facilities within the MACT floor that are using VSR. Mr.
Kensington asked about the origin of the vapor suppressed resin effectiveness
numbers. Ms. Strum stated that the 35% effectiveness credit for unfilled
resins came from test data and that tests of filled resin systems indicate
that suppressants in filled systems are generally ineffective. Ms. Strum
added that the standard would require case by case testing to determine
the effectiveness of the vapor suppressants used by individual facilities.
Mr. McNally questioned the effectiveness of vapor suppressants in reducing
methyl methacrylate emissions. Mr. Holtzclaw stated that due to secondary
bonding issues, corrosion resistant tanks and fittings often have to be
made from the same material, making mixing parts made from higher and
lower HAP resins impossible. Mr. Olsen suggested that EPA put an asterisk
on the maximum point value for mechanical application and note that the
point value also applies to all secondary parts and to attaching secondary
parts to the primary part, where the primary part is made by mechanical
application. Ms. Strum indicated that the facilities in the floor for
manual operations are also doing secondary bonding and so there is no
reason to separate out secondary bonding applications. She added that
she did not understand the issue since there were facilities in the floor
for manual operations that conduct secondary bonding. Ms. Koman stated
that a small group of people should look into the secondary bonding issue
further. Persons indicating they would participate included: John Schweitzer,
Bill Holtzclaw, Dan Boyd, and Neil Olsen.
Mr. Kensington stated that he believed that the data for facilities
setting the corrosion resistant floor were incorrect and that EPA needed
to visit these facilities. EPA explained that the facilities confirmed
the data in writing. Mr. Schweitzer also stated that he believed the data
in the database were wrong. After additional discussion, it was agreed
that EPA would send the CFA the copies of contact reports for companies
setting the MACT floor so that CFA could review the information.
Mr. DeBusk asked why there is a difference in the point value limit
for filled and unfilled mechanical resin application. Ms. Strum indicated
that non-atomized application (pressure-fed rollers, flow-coaters) was
not considered a viable control option for filled resin systems and therefore
the EPA decided to separate unfilled and filled mechanical resin application.
Ms. Strum added that tests done both by CFA and elsewhere have shown that
the effectiveness of vapor suppressants are greatly reduced in filled
resins as compared to unfilled resins. Mr. DeBusk indicated that his company
was applying a filled resin system using pressure-fed rollers. Ms. Proctor
asked what type of filler was contained in the filled resin system applied
with pressure-fed rollers. Mr. DeBusk indicated that the filler was aluminum
trihydrate. Ms. Proctor indicated that if filled resin systems could be
applied with non-atomized application, then it may be possible for the
EPA to recombine filled and unfilled mechanical resin application. Mr.
DeBusk inquired why the EPA had not separated filament winding application
into filled and unfilled groupings. Ms. Proctor responded that there were
very few facilities in the filament winding database that used filled
resin systems. Mr. DeBusk responded that approximately 80% of the resin
that his facility used to produce filament wound parts is filled.
Mr. Schweitzer asked if any of the representatives in attendance knew
if their facilities used styrene for cleaning purposes. Mr. Multanen answered
in the affirmative, but stated that they reused the styrene afterwards
in the fabrication process. Mr. Multanen asked if a facility reuses styrene
after cleaning, is this use considered cleaning or part of the fabrication
process. Mr. Schweitzer stated that cleaning with styrene should not be
prohibited as long as the styrene is reused in the production process.
Ms. Strum stated that the EPA would need to address this issue.
Mr. Holtzclaw asked about the proposed requirement for mixers to be
completely covered with no visible gaps around the mixing shaft. Mr. Holtzclaw
stated that resins were often mixed in 55 gallon drums with the mixing
shaft going through the bung hole located in the top of the 55-gallon
drum. Mr. Miles indicated that a large number of gel coats are also mixed
in 55 gallon drums. Mr. Holtzclaw asked if the proposed standard for mixing
would allow for a visible gap around the mixing shaft for this type of
mixing. Ms. Proctor responded in the negative and asked Mr. Holtzclaw
if facilities could seal the mixing shaft in some way. Mr. Holtzclaw responded
in the negative. Mr. Kensington stated that covering the mixer is good
enough and that a requirement for no visible gaps or seals is not necessary.
Mr. Spaulding asked if the mixing cover requirement could be changed to
"mostly covered" or "substantially covered" or "reasonable covered". Ms.
Elmore stated that those terms were unenforceable (due to being vague)
and that any cover requirement would have to be expressed in enforceable
terms. Mr. Spaulding asked if the standard could be written to allow for
a certain maximum gap size. Ms. Strum indicated that the EPA would investigate
the allowance of a gap between the mixing shaft and the mixer cover. Ms.
Strum asked what size gap would be needed. Attendees suggested allowing
a two-inch gap, a one and a half inch gap, or a half inch visible gap
around the mixer shaft, as well as determining an allowable gap as a factor
of the diameter of the mixer shaft. Mr. DeBusk stated that filler is often
added during the mixing process and inquired if the standard would allow
the mixer to be open when adding filler. Ms. Proctor indicated that the
current EPA approach would allow the mixer to be open for the purpose
of adding materials.
Mr. McNally stated that the CFA has recommended that mixing vessels
with less than a 25-gallon capacity be exempted from a mixer cover requirement.
Mr. McNally then inquired if the EPA would provide a technical recommendation
on how to supplant small batch mixers that have less than 25 gallons of
capacity or if the EPA would allow a size cutoff. Ms.
Strum indicated that the EPA could examine whether a size cutoff for mixing
vessels was warranted. Mr. Holtzclaw indicated manual mixing in a 5-gallon
pail is a common practice in industry and inquired if this type of mixing
would require a cover. Ms. Strum indicated that the EPA intended to exempt
hand mixing from the mixing cover requirement. It was inquired whether
hand mixing with a motorized device such as a mixing shaft on a drill
motor would be exempt. Ms. Strum answered in the negative and stated that
EPA would need to develop a definition of hand mixing.
Mr. Holtzclaw asked if EPA's requirement for covered storage containers
differentiated between when the material is being used and when the material
is being stored. Ms. Meyer inquired if this was an issue that EPA needed
to clarify. Mr. Multanen responded in the affirmative. Mr. Multanen stated
that in his facility, his employees frequently use small containers of
resin when fabricating products. Mr. Multanen asked if his employees would
have to cover those containers whenever they set the container down. Ms.
Elmore suggested that one way to address the issue raised by Mr. Holtzclaw
and Mr. Multanen would be to set a maximum length of time that a container
could be uncovered. Mr. Kensington asked if there was a size cutoff for
the covered storage container requirement. Ms. Strum responded in the
negative. Mr. Kensington held up a coffee cup and stated that there were
temporary containers in use at his facility that were as small as the
coffee cup he held in his hand. Mr. Kensington also stated that containers
this small should not be subject to the storage container requirement.
Mr. McNally indicated that it was unreasonable for the EPA to require
covers on small storage containers. Mr. McNally continued by stating that
this was especially true since the CFA had submitted to the EPA emissions
data that indicated that HAP emissions from small containers were insignificant.
Mr. Miles stated that industry needs controlled spraying in order to
meet the point value limits required by the standard. Mr. Miles stated
that testing has demonstrated that controlled spraying reduces emissions
and that industry should be provided with incentives (in the standard)
to use controlled spraying. Mr. Miles also indicated that controlled spraying
could be made enforceable. Mr. Multanen inquired why controlled spraying
was not considered enforceable. Ms. Strum indicated that the CFA controlled
spraying program had been ruled unenforceable by EPA's Office of Enforcement.
Ms. Strum added that operator training would be included as part of the
standard as a required work practice, but controlled spraying would not
be included as a control option in the point value system for open molding.
Mr. Miles stated that if a facility was operating a controlled spraying
program in a manner similar to an ISO 9000 type of quality assurance program
that it should be enforceable. Mr. Schweitzer stated that industry representatives
should be allowed to present to EPA's Office of Enforcement a modified
version of CFA's program of controlled spraying that is designed to address
EPA's enforceability concerns. Ms. Meyer inquired as to when the CFA would
have a modified proposal ready to present to the EPA, and Mr. Schweitzer
stated that he would provide EPA with a date by September 22, 1998 when
the CFA would be ready to present a modified control spraying proposal.
Mr. Hood raised a question about the ability of companies to meet MACT
standards while under a government contract requiring them to use particular
resins. Mr. Hood stated that the U.S. Military and governmental agencies
often have specific requirements for resins used in fire-retardant applications.
He gave an example of building code requirements in Los Angeles which
require the use of fire-proof panels. He said that these panels must be
manufactured from Class 1 fire retardant resins which have a HAP content
high enough to make them difficult to use under the proposed MACT standards.
Ms. Koman asked if a list of those required resins could be provided to
EPA. Mr. Hood then asked about corrosion resistant and fire retardant
resins being interchangeable under the proposed rule. Ms. Proctor stated
that the current EPA approach does not consider a fire-retardant product
or application to automatically be a corrosion resistant product or application.
Mr. Hood stated that if these resins could be classified in the corrosion
resistant product grouping, the high HAP content would not cause as much
of a compliance issue for facilities using the resins.
Mr. Hood inquired about the definition of corrosion resistance. After
a discussion on common uses of these resins and the possibility of defining
corrosion resistance based on chemistry, Ms. Proctor stated that the definition
of "corrosion resistant" needs to be defined by the application. Mr. Multanen
stated that there are currently many applications for higher HAP corrosion
resistant resins in non-corrosion resistant applications due to their
high quality and low shrinkage. For example, certain sections of the tub
and shower units produced by Mr. Multanen's company for a major hotel
chain are produced using a corrosion resistant resin. Mr. Multanen added
that changing to lower HAP corrosion resistant resins may not be economically
feasible. Ms. Koman asked that such situations be documented and submitted
to EPA to aid in the economic analysis. Ms. Koman added that any company
which does not want the information to be public record can submit it
as confidential business information.
Mr. Miles asked about the economic impact analysis. Ms. Chappell
explained the economic impact analysis is currently underway and stated
that information that would be helpful in the costing process includes
annual revenues, units produced, sales figures, change in sales, profit
margins, and costs of switching materials. She stated that it would be
particularly useful to know if the MACT standard would cause facilities
to change their product production. Some manufacturers agreed to provide
this information if it would be kept confidential. Ms. Chappell agreed
to send a list of questions about needed facility information to the CFA.
Mr. Spaulding indicated his belief that resins used for mold manufacturing
should be grouped with corrosion resistant applications. He stated that
because tooling gel coats were broken out separately from other gel coats,
tooling resins should be broken out separately from other resins. Mr.
Spaulding added that it would be unnecessary to create another process/product
grouping for mold manufacturing. Mr. Hood stated that isophthalic resins
were typically used for mold making and these resins required higher HAP
contents. Ms. Strum asked if vinyl ester resins were ever used in the
industry for mold manufacturing. Mr. Spaulding indicated that vinyl ester
resins were occasionally used by the industry. Ms. Strum pointed out that
data from the boat manufacturing industry indicated that several boat
facilities use low HAP vinyl ester resins to build molds. Mr. Multanen
stated that molds are constantly sprayed with chemicals that contain styrene
(a corrosive chemical) and as such should be considered a corrosion-resistant
application. Ms. Strum indicated that she did not see a difference between
a boat mold being sprayed with a resin and a mold used to produce a non-boat
product.
Mr. DeBusk asked about the possibility of exemptions for unique products.
He said that Appalachian Plastics developed a product with performance
characteristics that can only be achieved with a modified acrylic resin
that contains 60% HAP (mostly methyl methacrylate.) Mr. DeBusk stated
that currently the facility is considered a minor source, but with the
anticipated growth for this product, it could become a major source. Mr.
DeBusk stated that he could currently make the unique product under the
proposed standard by averaging in another product that uses a low HAP
resin, but his continuing ability to do so would depend on the market
for the latter product. Furthermore, Mr. DeBusk said that this higher
HAP resin had many applications and the current requirements would not
allow his company to grow. Mr. DeBusk stated that they currently cannot
afford a control device. Mr. Noonan asked whether the operation utilizing
the 60% by weight HAP resin was filled. Mr. DeBusk stated that it was
highly filled. Mr. Noonan said that the problem was EPA's treatment of
filled resins. Mr. McNally disagreed, indicating that this unique product
was a good example of where the industry was headed and raised the question
about how future products with similar issues would be addressed under
the standard. Mr. McNally added that he felt there is no MACT floor for
this industry. Ms. Meyer asked Mr. McNally to provide a rationale for
this position.
Many attendees expressed concern over Aker Plastics, Inc. presence in
the gel coat floor because of their use of a low HAP gel coat that is
not applicable to products in the industry that need to withstand weathering.
Ms. Proctor indicated that Cook carries low HAP gel coats for other applications,
for example, marine applications. Mr. Spaulding indicated that his Cook
Composites Representative did not recommend this low HAP gel coat. Mr.
Schweitzer expressed concern over using information from suppliers for
regulatory development. He stated that suppliers often indicate they have
a new product before all of the problems have been worked out and that
suppliers have had to pull papers they have prepared from conferences
at the last minute because their product was not ready. Mr. Hood stated
that he did not believe that the 24.3% gel coat made by Cook Composites
was widely available to all companies. He said that his distributor does
not have this gel coat. Mr. Multanen stated that some companies may have
special relationships with resin and gel coat manufacturers and distributors
which allow them to purchase a wider selection of resins and gel coats
at a lower cost. Mr. Schweitzer stated that he believed most low HAP gel
coats to still be under development or inaccessible to many companies.
Ms. Proctor indicated that she would check back on the availability of
the Cook low HAP gel coat and discuss whether the company recommends that
the low HAP marine gel coat not be used.
Mr. Mark Aker spoke about his experience with the low HAP gel coat.
He stated that Aker Plastics uses more than 3,000,000 pounds per year
and have been using the low HAP gel coat for two years. Mr. Aker continued
by stating that it initially took six months to adjust to the new gel
coat. Mr. Aker added that although the gel coat costs more per pound,
less is needed to produce products, thus actually reducing overall production
costs. Mr. Aker also stated that the application of this resin must be
controlled to a thickness of 3 mils in order to be cost effective. Many
attendees stated that they would not be able to achieve that tight of
a specification. Mr. Aker concluded by stating that he could not say that
their low HAP gel coat would work for all companies but that he also felt
that some companies in the industry were simply going to have to "step
up to the plate" and try the new low HAP gel coats and resins. Mr. Naylor
said that it is possible that companies that make repetitive products
may be at an advantage when changing their gel coats to lower HAP versions.
Mr. Naylor added that if a company makes a variety of products with different
required physical properties that it would have to test out a wider variety
of low-HAP gel coats (in order to obtain the required product properties)
and thus could encounter additional costs or technical difficulties. Attendees
identified this as a small business issue, noting that while a big company
like Aker would have the technical resources to make the low HAP gel coat
work, small businesses do not have resources needed to do this. They also
noted that this was a custom product versus repetitive product issue,
in that facilities making repetitive products would be more focused on
the one product and could devote the resources to that product.
Action Items for Industry Representatives:
1. By September 22, will give a date by which proposal to address concerns
about the controlled spraying compliance option will be completed.
2. Report of industry group on secondary bonding issues during the week
of September 22.
3. Submit specific information regarding concerns and suggestions to
EPA directly or through CFA. Helpful information includes: annual revenues,
units produced, sales figures, change in sales, profit margins, costs
of switching materials.
4. Provide examples of government specifications or requirements for
use of certain higher HAP resins.
Action Items for EPA:
1. Post meeting summary on the web.
2. Post averaging example on the web that illustrates the averaging allowed
between the process/product groupings of the open molding subcategory.
After further thought, the EPA decided that since this example is not
self-explanatory and that it would be counter productive to include it
on the website. However, the EPA will give an averaging demonstration
at the CFA's Annual Convention on October 23, 1998.
3. Send contact reports to CFA. (Sent September 21, 1998)
