I. Background 


A. Overview of the Problem of Ozone Depletion 

   The stratospheric ozone layer protects the earth from the 
penetration of harmful ultraviolet (UV-B) radiation. On the 
basis of substantial scientific evidence, a national and
international 
consensus exists that certain man-made halocarbons, including 
chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and 
methyl chloroform (MCF), must be restricted because of the risk 
of depletion of the stratospheric ozone layer through the release 
of chlorine and bromine (WMO/UNEP Science Assessment). To the 
extent depletion occurs, penetration of UV-B radiation increases, 
resulting in potential health and environmental harm including 
increased incidence of certain skin cancers and cataracts,
suppression 
of the immune system, damage to plants including crops and aquatic 
organisms, increased formation of ground-level ozone and increased 
weathering of outdoor plastics. (See 53 FR 30566 for more
information 
on the effects of ozone depletion.) 
   The original theory linking CFCs to ozone depletion was first 
proposed in 1974. Since then, the scientific community has made 
considerable advances in measuring and understanding the
atmospheric 
processes affecting stratospheric ozone science. Repeatedly, 
these scientific advances have indicated that the impact of 
man-made ozone-depleting substances on the stratosphere was 
more severe than previously thought. As discussed below, the 
U.S. and the international community have adopted increasingly 
stringent policies regarding the manufacture and use of ozone-
depleting substances in response to this evolving scientific 
understanding. 

B. Aerosol Ban in 1978 

   Following initial concerns raised by research scientists 
Molina and Rowland in 1974 regarding possible ozone depletion 
from CFCs, EPA and the Food and Drug Administration (FDA) acted 
on March 17, 1978 (43 FR 11301; 43 FR 11318) to ban the use 
of CFCs as aerosol propellants in all but ``essential
applications.'' 
During the mid-1970s, use as aerosol propellants constituted 
over 50 percent of total CFC consumption in the United States. 
The 1978 ban reduced aerosol use of CFCs in this country by 
approximately 95 percent, eliminating nearly half of the total 
U.S consumption of these chemicals. 
   Some CFC aerosol products were specifically exempted from 
the ban based on a determination of ``essentiality.'' (See
reference 
Essential Use Determinations-Revised, 1978.) Other pressurized 
dispensers containing CFCs were excluded from the ban because 
they did not fit the narrow definition of ``aerosol propellant.'' 
   In the years following the aerosol ban, CFC use increased 
significantly in the refrigeration, foam and solvent-using
industries. 
By 1985, CFC use in the United States had surpassed pre-1974 
levels and represented 29 percent of total global CFC consumption. 

C. Montreal Protocol 

   In response to the discovery of the ozone hole over Antarctica 
and to growing evidence that chlorine and bromine could destroy 
stratospheric ozone on a global basis, many members of the
international 
community came to the conclusion that an international agreement 
to reduce global production of ozone-depleting substances was 
needed. Because releases of CFCs from all areas mix in the
atmosphere 
to affect stratospheric ozone globally, efforts to reduce emissions

from specific products by only a few nations could quickly be 
offset by increases in emissions from other nations, leaving 
the risks to the ozone layer unchanged. EPA evaluated the risks 
of ozone depletion in Assessing the Risks of Trace Gases That 
Can Modify the Stratosphere (1987) and concluded that an
international 
approach was necessary to effectively safeguard the ozone layer. 
   In September 1987, the United States and 22 other countries 
signed the Montreal Protocol on Substances that Deplete the 
Ozone Layer (the Protocol). As originally drafted, the Protocol 
called for production and consumption of certain CFCs (CFC-11, 
12, 113, 114, 115) and halons (Halon-1211, 1301 and -2402) to 
be frozen at 1986 levels beginning July 1, 1989, and January 
1, 1992, respectively, and for the CFCs to be reduced to 50 
percent of 1986 levels by 1998. To date, over 100 nations
representing 
approximately 95% of the world's production capacity for CFCs 
and halons have signed the Montreal Protocol. EPA promulgated 
regulations implementing the requirements of the 1987 Protocol 
through a system of tradeable allowances. EPA apportioned the 
allowances to producers and importers of ozone-depleting substances

(controlled substances) based on their 1986 level of production 
and importation. It then reduced the allowances for the controlled 
substances according to the schedule specified in the Protocol. 
(See 56 FR 49548 (September 30, 1991) for a more detailed
discussion 
of the Protocol and EPA's regulations to implement the phaseout 
of ozone-depleting substances.) To monitor industry's compliance 
with the production and consumption limits, EPA required
recordkeeping 
and quarterly reporting and conducted periodic compliance reviews 
and inspections. 

D. Excise Tax 

   As part of the Omnibus Budget Reconciliation Act of 1989, 
Internal Revenue Code of Ozone-Depleting Substances, section 
506A of Public Law 101-239, the United States Congress levied 
an excise tax on the sale of CFCs and other chemicals which 
deplete the ozone layer, with specific exemptions for exports 
and recycling. The tax went into effect on January 1, 1990, 
and increases annually. The original excise tax was amended 
by the Omnibus Budget Reconciliation Act of 1991 to include 
methyl chloroform, carbon tetrachloride and the other CFCs
regulated 
by the amended Montreal Protocol and Title VI of the Clean Air 
Act, as amended in 1990. The Energy Policy Act of 1992, section 
1931 of Public Law 102-486, revised and further increased the 
excise tax, effective January 1, 1993. By raising the cost of 
virgin controlled substances, the tax has created an additional 
incentive for industry to shift out of these substances and 
increase recycling activities, and it has encouraged the
development 
of a market for alternative chemicals and processes. 

E. London Amendments to the Montreal Protocol 

   Under Article 6 of the Montreal Protocol, the Parties are 
required to assess the science, economics and alternative
technologies 
related to protection of the ozone layer every two years. In 
response to this requirement, the Parties issued their first 
scientific assessment in 1989 (Scientific Assessment of Ozone 
Depletion, which has been placed in the docket for this
rulemaking.) 
During this assessment, scientists examined the data from land-
based monitoring stations and the total ozone mapping spectrometer 
(TOMS) satellite and found that there had been global ozone 
depletion over the northern hemisphere as well as over the southern

hemisphere. The scientific assessment also reported that a three 
to five percent decrease in stratospheric ozone levels had occurred

between 1969-1986 in the northern hemisphere in the winter months 
that could not be attributed to known natural processes. 
   At the Second Meeting of the Protocol Parties, held in London 
on June 29, 1990, the Parties responded to this new evidence 
by tightening the restrictions placed on these chemicals. The 
Parties to the Protocol passed amendments and adjustments which 
called for a full phaseout of the already regulated CFCs and 
halons by 2000, a phaseout of carbon tetrachloride and ``other 
CFCs'' by 2000 and a phaseout of methyl chloroform by 2004. 
The Parties also passed a non-binding resolution regarding the 
use of hydrochlorofluorocarbons (HCFCs) as interim substitutes 
for CFCs. Partially halogenated HCFCs add much less chlorine 
to the stratosphere than the fully halogenated CFCs, but still 
pose a significant longer term threat to the ozone layer. (See 
56 FR 2420 January 22, 1991 for more information on the relative 
effects of different ozone-depleting substances.) 

F. Clean Air Act Amendments of 1990, Title VI 

   On November 15, 1990, the Clean Air Act Amendments of 1990 
(CAAA) were signed into law. The requirements in Title VI of 
the Clean Air Act as amended (the Act) include phaseout controls 
similar to those in the London Amendments, although the interim 
targets are more stringent and the phaseout date of methyl
chloroform 
is earlier (section 604). Other Title VI provisions require 
EPA to promulgate additional controls pertaining to the protection 
of the stratospheric ozone. These provisions (1) restrict
production 
and consumption of HCFCs (section 605); (2) restrict the uses 
of controlled ozone-depleting substances, including provisions 
to reduce emissions of controlled substances to the ``lowest 
achievable level'' in all use sectors (section 608); (3) require 
the recovery and recycling of refrigerant when servicing motor 
vehicle air conditioners (section 609); (4) ban nonessential 
products (section 610); (5) mandate warning labels (section 
611); (6) establish a safe alternatives program (section 612); 
and (7) require revision of federal procurement policies to 
minimize government use of ozone-depleting substances (section 
613). EPA has already promulgated regulations implementing the 
phaseout provisions contained in section 604 of the Act (57 
FR 33754), the motor vehicle air conditioner recovery and recycling

provisions (57 FR 31241), the section 608 recycling provisions 
(58 FR 28660), the section 610 ban on class I nonessential uses 
(58 FR 4767), and the section 611 labeling requirement (58 FR 
8135). EPA is currently in the process of promulgating regulations 
under several other sections of Title VI. 
   The Act divides ozone-depleting chemicals into two distinct 
classes based on their ability to destroy ozone in the
stratosphere. 
Class I substances are those substances listed in section 602(a), 
as well as any substance that the Administrator finds ``causes 
or contributes significantly to harmful effects on the
stratospheric 
ozone layer.'' In addition, the Administrator is to add any 
substance to the list of class I substances determined to have 
an ozone depletion potential (ODP) of 0.2 or greater (ozone 
depletion potential reflects the destructiveness of an ozone-
depleting substance relative to CFC-11). Class I substances 
include CFCs, halons, carbon tetrachloride and methyl chloroform. 
Class II substances have ODPs lower than 0.2. Class II consists 
exclusively of HCFCs (see listing notice, January 22, 1991, 
56 FR 2420). EPA is currently evaluating other substances to 
determine whether they meet the criteria for Class I or Class 
II substances. 
   One of the provisions of the Act that complements the ban 
on nonessential products is the Significant New Alternatives 
Program (SNAP) established under section 612. The Notice of 
Proposed Rulemaking (NPRM) for this program was published in 
the Federal Register on May 12, 1994 (58 FR 28094). The SNAP 
program has been established to evaluate the overall effects 
on human health and the environment of the potential substitutes 
for ozone-depleting substances. Rules promulgated under SNAP 
will render it unlawful to replace an ozone-depleting substance 
with a substitute chemical or technology that may present adverse 
effects to human health and the environment if the Administrator 
determines that some other alternative is commercially available 
and that this alternative poses a lower overall threat to human 
health and the environment. The SNAP program is a powerful tool 
for ensuring that ``acceptable'' alternatives are developed. 

G. Accelerated Phaseout of Ozone-Depleting Substances 

   Based on new scientific evidence developed since the passage 
of the Clean Air Act Amendments and the issuance of implementing 
regulations, the international community, led by the United 
States, has agreed in November of 1992, to accelerate further 
the phaseout of already regulated ozone-depleting substances 
and control additional substances pursuant to this agreement. 
Production of virtually all class I substances will be phased 
out in less than three years (by January 1, 1996) and halons 
will be phased out by January 1, 1994. EPA published a Notice 
of Proposed Rulemaking on the accelerated phaseout in the Federal 
Register on March 18, 1993, (58 FR 15013) that sets out specific 
phaseout schedules for ozone depleters. 
   EPA believes that its decision in this rulemaking on the 
class II nonessential products ban should take into account 
the significantly shortened life span of ozone-depleting substances

resulting from the accelerated phaseout and the correspondingly 
diminished impact a ban on the sale and distribution of certain 
products containing or manufactured with class II substances 
would be expected to have. The following section describes the 
most recent scientific and international developments regarding 
ozone depletion. 

1. New Scientific Data Regarding Ozone Depletion 

   Significant scientific advances have occurred since the initial 
Protocol assessments in 1989. Several subsequent reports since 
that time have indicated a more rapid rate of ozone depletion 
than previously believed. The most recent Montreal Protocol 
Scientific Assessment, issued December 17, 1991, contains
information 
from ground-based monitoring instruments, as well as from satellite

instruments, from the years 1979-1991. The data indicate
significant 
decreases in total-column ozone have occurred in winter, and 
for the first time, also show decreases in spring and summer, 
in both the northern and southern hemispheres at middle and 
high latitudes. The data further show no significant depletion 
has occurred in the tropics. TOMS data indicate that for the 
period 1979 to 1991, decreases in total ozone at 45 degrees 
south latitude ranged between 4.4 percent in the fall to as 
much as 6.2 percent in the summer, while depletion at 45 degrees 
north latitude ranged between 1.7 percent in the fall to 5.6 
percent in the winter. Data from the ground-based Dobson network 
confirm these losses in total column ozone during the thirteen-
year period; those trends were statistically significant for 
all four seasons. The comparable ozone depletion measured by 
the Dobson network shows a decrease of 2.7 percent per decade 
in winter, 1.3 percent per decade in summer, and 1.0 percent 
per decade in fall for North America, Europe and the Far East. 
These findings show almost twice as much depletion as the seasonal 
average rates measured by the ground-based network over a twenty-
year period. Based on this new data, scientists have concluded 
that the ozone in the stratosphere during the 1980s disappeared 
at a much faster rate than experienced in the previous decade. 
   The recent UNEP Science Assessment also includes new data 
on the estimated ozone depletion potentials (ODPs) of ozone-
depleting substances. The assessment placed the ODP of methyl 
bromide, a chemical previously thought to have an insignificant 
effect on stratospheric ozone, at 0.6, with a range of uncertainty 
between 0.44-0.69. On November 25, 1992, the Parties to the 
Montreal Protocol agreed to assign methyl bromide an ODP of 
0.7 (based on an update of the science assessment). 
   On February 3, 1992, NASA released preliminary data acquired 
by the ongoing Arctic Airborne Stratospheric Experiment-II (AASE-
II), a series of high-altitude instrument-laden plane flights 
over the northern hemisphere (see Interim Findings: Second Airborne

Arctic Stratospheric Expedition). Additional data were also 
obtained from the initial observations by NASA's Upper Atmosphere 
Research Satellite (UARS), launched in September 1991. The
measurements 
show higher levels of chlorine monoxide (ClO) (the key agent 
responsible for stratospheric ozone depletion) over Canada and 
New England than were observed during any previous series of 
aircraft flights. In fact, the ClO levels over the United States 
and Canada and as far south as the Caribbean were many times 
greater than gas phase models had predicted. These levels are 
only partially explainable by enhanced aerosol surface reactions 
due to emissions from the volcanic eruptions of Mount Pinatubo. 
The expedition also found that the levels of hydrogen chloride 
(HCl), a chemical species that stores atmospheric chlorine in 
a less reactive state, to be low, providing new evidence for 
the existence of chemical processes that convert stable forms 
of chlorine into ozone-destroying species. 
   In addition, the levels of nitrogen oxides (NOX) were also 
observed to be low, providing evidence of reactions that take 
place on the surface of aerosols that diminish the ability of 
the atmosphere to control the buildup of chlorine radicals. 
New observations of HCl and nitrogen oxide (NO) imply that chlorine

and bromine are more effective in destroying ozone than previously 
believed. 
   The NASA findings indicate that in late January of 1992, 
the Arctic air was chemically ``primed'' for the potential
formation 
of a springtime ozone ``hole'' similar to that formed each spring 
over Antarctica. These findings also are consistent with theories 
that ozone depletion may occur at an accelerated rate on aerosol 
surfaces in the stratosphere anywhere around the globe, and 
not only on polar stratospheric clouds as was previously believed. 
   After collecting more data, NASA released an April 30, 1992 
``End of Mission Statement,'' which indicated that while a rise 
in stratospheric temperatures in late January prevented severe 
ozone depletion from occurring in the Arctic this year, observed 
ozone levels were nonetheless lower than had previously been 
recorded for this time of year. This information has further 
increased the Agency's concern that significant ozone loss may 
occur over populated regions of the earth, thus exposing humans, 
plants and animals to harmful levels of UV-B radiation, and 
adds support to the need for further efforts to limit emissions 
of anthropogenic chlorine and bromine. 
   In April of 1993, NASA released additional data for the second 
half of 1992. NASA found that ozone levels were 2 percent lower 
than any previous year and 3 percent lower than normal. The 
1992 low ozone levels were especially low in the mid-latitudes 
of the northern hemisphere. The December 1992 mid-latitude ozone 
levels were 9 percent below normal. The January 1993 ozone levels 
were 13-14 percent below normal. The low mid-latitude ozone 
values continue into 1993, and have continued through the spring 
and early summer. Scientists can only speculate on the cause 
of the low ozone levels, but the low ozone may be related to 
the continuing presence of particles from the Mt. Pinatubo eruption

in the Philippines in June 1991. 

2. Copenhagen Revisions to the Montreal Protocol 

   On November 25, 1992, the Fourth Meeting of the Montreal 
Protocol was convened. In this meeting, the Parties took a number 
of actions, including accelerating the phaseout schedule of 
CFCs, halons, carbon tetrachloride, and methyl chloroform and 
added HCFCs and methyl bromide to the list of chemicals to be 
controlled under the Montreal Protocol. 
   The following adjustments to the phaseout schedules of
previously-
controlled substances were adopted at the Copenhagen meeting: 
   (a) Accelerating the phaseout schedule for the originally-
controlled CFCs (class I, group I substances) to require a 75% 
reduction in production and consumption (production plus imports 
minus exports) from 1986 baseline levels for 1994 and 1995, 
and a complete phaseout by 1996; 
   (b) Accelerating the phaseout schedule for halons (class 
I, group II substances) to require a complete phaseout in
production 
and consumption by 1994; 
   (c) Accelerating the phaseout schedule for other fully
halogenated 
CFCs (class I, group III substances) to require a reduction 
from 1989 levels, 75% in 1994 and 1995, and a complete phaseout 
of production and consumption by 1996; 
   (d) Accelerating the reduction schedules for carbon
tetrachloride 
(class I, group IV) by requiring a reduction from 1989 levels 
of 85% in 1995, and a complete phaseout in 1996; 
   (e) Accelerating the phaseout schedule for methyl chloroform 
(class I, group V) by reducing production and consumption to 
50% of 1989 levels in 1994, and phasing out completely by 1996; 
and 
   (f) Establishing criteria for identifying essential uses 
and a process for excepting limited production and consumption 
of the above chemicals following their phaseout dates (see below). 
   These adjustments are to go into effect six months after 
the United Nations Depositary circulates the adjustments to 
the Protocol Parties. 
   In addition, the Parties adopted the following amendments 
to the Protocol: 
   (a) Freezing consumption of HCFCs (class II substances)
beginning 
in 1996 at a baseline level of 100% of 1989 the ozone depletion 
potential (ODP) weighted level of HCFC consumption, plus 3.1% 
of the ODP-weighted 1989 CFC consumption, followed by reductions 
in the baseline to 65% of the baseline level by January 1, 2004, 
to 35% of the baseline by 2010, to 10% of the baseline by 2015, 
to 0.5% of the baseline by 2020; and completely phasing out 
consumption by 2030; 
   (b) Adding hydrobromoflourocarbons (HBFCs) to the list of 
controlled substances, specifying their ozone depletion potential, 
and phasing their production and consumption out completely 
by 1996; 
   (c) Listing methyl bromide as a controlled substance with 
an ozone depletion potential of 0.7, and freezing its production 
and consumption beginning in 1995 at 1991 consumption levels; 
(not including amounts used for quarantine and preshipment uses); 
   (d) Establishing a procedure for the approval by the Parties 
for continued production and consumption after phaseout to meet 
essential use requirements; essential uses are defined as those 
necessary for health or safety, or critical to the functioning 
of society, and where there are no available alternatives or 
existing stocks of banked or recycled material; 
   (e) Establishing reporting requirements for HCFCs, HBFCs, 
and methyl bromide;
   (f) Establishing reporting requirements for imports and exports 
of recycled halons and HCFCs; and 
   (g) Amending the Article 4 restriction on imports and exports 
of controlled substances to and from foreign states not party 
to the Protocol. 
   The Amendments will enter into force under the Protocol
following 
their ratification by at least twenty Parties. This is projected 
to be accomplished by January 1, 1994. 
   The Parties also made a number of decisions regarding procedures

and definitions that affect implementation of the Protocol and 
that are addressed in the proposal concerning the accelerated 
phaseout (58 FR 15013). The decisions include: 
   (a) The approval of certain destruction technologies and 
the requirement that Parties that plan to operate destruction 
facilities do so in accordance with Good Housekeeping Procedures 
developed by the Parties or with their equivalent; 
   (b) Clarification of the definition of controlled substances 
to exclude insignificant quantities under defined circumstances, 
and to encourage Parties to minimize emissions of such excluded 
substances; 
   (c) Clarification of the reporting requirements and treatment 
of international transshipment; and 
   (d) Clarification of the definition of controlled substance 
to exclude the import and export of recycled and used controlled 
substances from the calculation of consumption, but to require 
reporting of data concerning these imports and exports. 

3. The Proposed Accelerated Phaseout Regulation

   In July 1992, EPA issued its final rule and regulatory program 
implementing section 604 of the Clean Air Act Amendments. Section 
604 limits the production and consumption of ozone-depleting 
chemicals. EPA controls production and consumption by issuing 
allowances that are expended in the production or importation 
of these chemicals. Trading of these allowances is permitted. 
   The regulation requires producers of class I substances to 
gradually reduce their production of these chemicals and to 
phase them out completely as of January 1, 2000 (2002 for methyl 
chloroform). In addition to the production limits, the rule 
requires a similar reduction in consumption. 
   In February 1992, President Bush requested that U.S. producers 
voluntarily reduce their production of CFCs by half of the baseline

year levels and phase out CFCs, carbon tetrachloride, methyl 
chloroform and halons by January 1, 1996. He also announced 
that the U.S. would revisit the phaseout schedule for HCFCs. 
   Prior to that announcement, EPA had received a petition from 
the Natural Resources Defense Council (NRDC), the Environmental 
Defense Fund (EDF) and Friends of the Earth (FOE), requesting 
earlier phaseouts of ozone-depleting substances and that EPA 
add methyl bromide to the list of class I substances and also 
phase out its production. Another petition was subsequently 
submitted by the Alliance for Responsible CFC Policy that also 
supported earlier phaseouts of CFCs and certain HCFCs. 
   Based on these developments, and the agreements reached by 
the Parties to the Protocol in November of 1992, EPA recently 
published a Notice of Proposed Rulemaking (58 FR 15013) on March 
18, 1993, in which the Agency proposed accelerating the phaseout 
of CFCs, methyl chloroform, carbon tetrachloride, halons, HCFC-
141b, HCFC-142b, and HCFC-22. The Agency also proposed adding 
methyl bromide and HBFCs to the list of class I substances and 
phasing out their production and consumption. In addition, the 
proposed regulations would implement various trade provisions 
required by the Montreal Protocol by prohibiting the trade of 
bulk substances and products containing controlled substances 
with non-Parties. 

4. Effect of the Accelerated Phaseout on the Class II Ban 

   The accelerated phaseout will affect businesses that manufacture

aerosol products, pressurized dispensers, and foam with class 
II substances in several ways. First, the impending phaseout 
of class I substances such as CFCs and methyl chloroform will 
compel manufacturers to adopt replacements for them in their 
products. HCFCs are substitutes for class I substances in many 
applications, including the manufacture of some aerosols and 
foam products. Second, the restrictions placed on HCFCs in the 
accelerated phaseout, particularly the new phaseout dates for 
HCFC-141b, HCFC-142b, and HCFC-22 will limit the amount of time 
that these HCFCs would be available as substitutes for class 
I substances. Although HCFCs will be available as substitutes 
for only a limited period of time, there are conceivably certain 
product sectors where no other satisfactory alternative substance 
is currently available; in these sectors, HCFCs may provide 
important interim substitutes. However, the costs associated 
with reformulating aerosol products and foams, and of modifying 
manufacturing processes, are not insignificant; it generally 
takes a number of years to recoup the investment involved with 
such activity. Moreover, use of HCFCs as interim substitutes 
would require making these expenditures twice. In addition, 
many manufacturers have expressed the belief that Congress may 
in the future expand the excise tax on ozone-depleting substances 
to include HCFCs; such an action would increase the time necessary 
to recover such an investment. Under the accelerated phaseout 
schedule, the period of availability of HCFC-22, HCFC-141b and 
HCFC-142b may not be long enough for companies to consider them 
as economically viable substitutes. Consequently, the treatment 
of some HCFCs in the accelerated phaseout discourages the adoption 
of HCFCs as substitutes for class I products. Thus, EPA concludes 
that manufacturers will have significant incentive to limit 
uses of HCFCs independent of the ban on nonessential uses of 
class II substances. 

5. Effect of the Labeling Rule on the Class II Ban 

   Regulations regarding the labeling of containers of class 
I and class II substances and products using class I substances 
or manufactured with class I substances that are introduced 
into interstate commerce after May 15, 1993, were promulgated 
under section 611 of the Act and published in the Federal Register 
on February 11, 1993 (58 FR 8135). In addition, under the labeling 
rule, products containing or manufactured with a class II substance

must be labeled if EPA determines, ``after notice and opportunity 
for public comment, that there are substitute products or
manufacturing 
processes (A) that do not rely on the use of such class II
substances, 
(B) that reduce the overall risk to human health and the
environment, 
and (C) that are currently or potentially available.'' In addition,

all such products must be labeled, regardless of whether the 
criteria outlined above are met, if they are introduced into 
interstate commerce on or after January 1, 2015. EPA believes 
that some products exempted from the Class II Nonessential Products

Ban may be required at some point in the future, to bear warning 
labels. Under general principles of administrative procedure, 
EPA is bound to respond to requests from the public to require 
labeling of products containing or manufactured with class II 
substances.

H. Meetings With Industry and Environmental Organizations 

   In the development of this proposed regulation, EPA met with 
representatives from various environmental organizations and 
industries. The Agency also conducted two advisory meetings 
held in the EPA auditorium, on February 19, 1993 and March 29, 
1993, in order to allow the public to review draft background 
documents on products releasing class II substances and to offer 
comments and technical expertise on the development of today's 
proposed rule. Minutes of these meetings and copies of the
background 
documents are contained in Docket A-93-20. The Agency used these 
forums as appropriate venues for hearing the concerns of various 
stakeholders affected by this NPRM. 

II. Requirements Under Section 610 


A. Ban of Nonessential Products Releasing Class I Substances 

   Title VI of the Clean Air Act, as amended in 1990, divides 
ozone-depleting chemicals into two distinct classes. Class I 
is comprised of chlorofluorocarbons (CFCs), halons, carbon
tetrachloride 
and methyl chloroform. Class II is comprised of
hydrochlorofluorocarbons 
(HCFCs). (See listing notice January 22, 1991; 56 FR 2420.) 
Section 610(b) of the Act, as amended, requires EPA to promulgate 
regulations banning nonessential products releasing class I 
substances. EPA published its final rule for the Class I
Nonessential 
Products Ban in the January 15, 1993 (58 FR 4768). 
   In the final rule EPA banned, among other products, flexible 
and packaging foam, and aerosols and other pressurized dispensers 
using CFCs. In developing regulations to implement the class 
I ban, EPA took into consideration the statutory prohibition 
required by section 610(d) on products containing or manufactured 
with class II substances. EPA was concerned about the potential 
environmentally adverse incentive of banning the use of class 
II substances in certain products in 1994 while permitting the 
use of the more harmful class I substances in the same products. 
Thus, the statutory prohibition in section 610(d) provided
direction 
in choosing products on which to focus under section 610(b). 

B. Ban of Nonessential Products Containing or Manufactured with 
Class II Substances 

   Section 610(d)(1) states that after January 1, 1994, ``it 
shall be unlawful for any person to sell or distribute, or offer 
for sale or distribution, in interstate commerce-(A) any aerosol 
product or other pressurized dispenser which contains a class 
II substance; or (B) any plastic foam product which contains, 
or is manufactured with, a class II substance.'' Section 610(d)(2) 
authorizes EPA to grant exceptions and section 610(d)(3) creates 
exclusions from the class II ban in certain circumstances. 
   Section 610(d)(2) authorizes the Administrator to grant
exceptions 
from the ban of class II substances in aerosols and other
pressurized 
dispensers where ``the use of the aerosol product or pressurized 
dispenser is determined by the Administrator to be essential 
as a result of flammability or worker safety concerns,'' and 
where ``the only available alternative to use of a class II 
substance is use of a class I substance.'' 
   Section 610(d)(3) states that the ban of class II substances 
in plastic foam products shall not apply to ``foam insulation 
products'' or ``an integral skin, rigid, or semi-rigid foam 
utilized to provide for motor vehicle safety in accordance with 
Federal Motor Vehicle Safety Standards where no adequate substitute

substance (other than a class I or class II substance) is
practicable 
for effectively meeting such Standards.''
   EPA believes that, unlike the class I ban, the class II ban 
is self-executing.{1} Section 610(d) bans the sale of the specified

class II products by its own terms, without any reference to 
required regulations. Consequently, EPA was not required to 
promulgate regulations within one year of enactment under section 
610(a) to implement the class II ban.{2} EPA is today proposing 
regulations to implement the class II ban in order to better 
define the products banned under section 610(d) and to grant 
authorized exceptions under 610(d)(2). Section 301(a) gives 
EPA the authority to promulgate such regulations as are necessary 
to carry out its functions under the Act. EPA believes that 
it is necessary within the meaning of section 301 to promulgate 
regulations defining the products subject to the class II ban 
and granting exceptions to the ban under section 610(d)(2). 
      ³  {1}  Moreover, the Congressional Record statement by 
      ³Representative Ralph Hall (D-Texas) regarding the
Congressional 
      ³intent of the legislation as passed states ``Any
failure 
      ³of the Administrator to promulgate regulations as
required 
      ³by this title, or any court order delaying the
effective 
      ³date of such regulations, shall not alter the effective

      ³dates of the statutory requirements and prohibitions 
      ³that are set forth in this title (October 26, 1990, 136

      ³Congressional Record H12907).'' Thus, EPA has no
authority 
      ³to alter the effective date of the statutory ban. 
      ³  {2}  Although the legislative history of section 610 
      ³is unclear on this point, the Senate Statement of
Managers 
      ³specifically states that the section 608 ban on the
venting 
      ³of refrigerants, which like the class II ban is an
outright 
      ³prohibition, is self-executing and will take effect on 
      ³the stated date even if that date is in advance of EPA 
      ³regulations implementing the ban. EPA believes that
this 
      ³analysis applies similarly to the class II ban. See
Congressional 
      ³Record, page S16948, October 27, 1990. 

C. Medical Products 

   Section 610(e) states that ``nothing in this section shall 
apply to any medical devices as defined in section 601(8).'' 
Section 601(8) defines ``medical device'' as ``any device (as 
defined in the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 
321)), diagnostic product, drug (as defined in the Federal Food, 
Drug, and Cosmetic Act), and drug delivery system-(A) if such 
device, product, drug, or drug delivery system utilizes a class 
I or class II substance for which no safe and effective alternative

has been developed, and where necessary, approved by the
Commissioner 
of the Food and Drug Administration; and (B) if such device, 
product, drug, or drug delivery system, has, after notice and 
opportunity for public comment, been approved and determined 
to be essential by the Commissioner in consultation with the 
Administrator.'' 
   No medical products as defined above are prohibited by the 
provisions of today's proposal. 

III. Proposed Rule 

   EPA today proposes to implement the prohibition required 
by section 610(d) on the sale or distribution in interstate 
commerce of specified class II products. Many aspects of the 
proposed regulation are similar in structure to the section 
610(b) final rule on class I substances published on January 
15, 1993. Therefore, EPA is proposing to revise the regulations 
promulgated under 40 CFR part 82, subpart C to incorporate today's 
proposed regulations. EPA wishes to clarify that while today's 
proposal would revise these regulations, EPA is only requesting 
comment on the revisions, not on subpart C in its entirety. 
The following section discusses the provisions of the proposed 
regulation in greater detail. 

A. Ban on Sale or Distribution in Interstate Commerce 

   EPA believes that the term ``interstate commerce'' in section 
610(d) refers to the product's entire distribution chain up 
to and including the point of sale to the ultimate consumer. 
As such, all sales and distribution of banned products, including 
retail sales, would be prohibited as of January 1, 1994, as 
required by the Act, unless specified. EPA wishes to clear up 
any possible confusion about this provision by observing that 
the statutory language in section 610 is markedly different 
from that in section 611, the labeling provision. The Act banned 
the ``introduction into'' interstate commerce of certain products 
unless they were in compliance with the labeling requirements 
in section 611. Consequently, the restriction was essentially 
limited to the first sale of the affected product. Under section 
610, the statute prohibits all sale, distribution, or offer 
of sale or distribution in interstate commerce after the January 
1, 1994 effective date. 

1. Grandfathering 

   EPA believes that there generally should be sufficient time 
before the prohibition goes into effect on January 1, 1994 for 
manufacturers to alter production and for retailers to liquidate 
any remaining stocks of prohibited products. The Agency believes 
that the effect of this prohibition was quite clear to the affected

businesses prior to today's action; the statutory language clearly 
sets forth the universe of products potentially affected by 
this prohibition. EPA's rules establishing exemptions will serve 
only to limit the universe of products potentially subject to 
the class II ban, not to add any product to those specified 
in the statute. The publication of the Class I Nonessential 
Products Ban on January 15, 1993, definitively identified the 
remaining legal uses of CFCs in aerosol products (which were 
not significantly different from those contained in the January 
16, 1992 proposed rule). In addition, while the determinations 
made by EPA in the class I ban regarding foam products were 
not in any way binding on the section 610(d) rulemaking, the 
treatment of foam products in the class I ban clearly indicated 
the Agency's likely treatment of these products in the class 
II ban.{3} Businesses will have had over three years' lead time 
between enactment of the statute and the January 1, 1994 effective 
date of the class II ban in which to make changes in their
manufacturing 
processes and to liquidate existing inventories of banned products.

In general, EPA believes that this period of time constitutes 
adequate notice for the affected businesses; however, the Agency 
has been contacted by manufacturers and suppliers concerned 
with the treatment of existing inventories, especially where 
the breadth of the statutory ban was arguably ambiguous.
Furthermore, 
EPA realizes that in some limited cases, manufacturers have 
been unable to obtain federal approval to reformulate products, 
due to regulatory delays based on limited administrative
feasibility. 
Therefore, EPA proposes to provide two narrow exemptions from 
the class II ban for specific categories of products, based 
on equitable grounds. These proposed exemptions apply to existing 
inventories and to products for which federal approval is required 
prior to reformulation. 
      ³  {3}  One of the reasons EPA cited for banning aerosol

      ³and foam products containing CFCs was the concern that 
      ³banning certain products under the class II ban that 
      ³were not covered by the class I ban could, in certain 
      ³circumstances, create incentives for manufacturers to 
      ³use class I substances rather than class II substances,

      ³which would result in greater damage to the
stratospheric 
      ³ozone layer. Because EPA wanted to avoid such
situations 
      ³(and because the Agency shared Congress' belief that 
      ³satisfactory substitutes existed for ozone-depleting 
      ³substances in these products), it banned many of the 
      ³foam products in the class I ban that would be
prohibited 
      ³by the statute under the class II ban. 
   Without these exemptions, all existing inventories would 
need to be liquidated by January 1, 1994. EPA believes that 
in certain instances this liquidation might constitute an onerous 
burden on small businesses that may have purchased all or part 
of their inventory in advance of the Act or without adequate 
knowledge about the class II ban. EPA believes that little
environmental 
benefit can be gained by compelling these entities to liquidate 
their existing inventories. 
   Administrative creation of exemptions from statutory
requirements 
are authorized in only limited circumstances, outlined in Alabama 
Power Co., et al. v. Costle, et al., 636 F. 2d 323 (D.C. Cir 
1979). Agencies can create such exemptions only where necessary 
based on administrative feasibility or the de minimis nature 
of the exemption. The exemption EPA is proposing for existing 
inventories is based on the de minimis rationale, while that 
proposed for products requiring federal approval for reformulation 
is based on administrative feasibility. 
   Existing Inventories. EPA proposes to exempt existing
inventories 
of products otherwise subject to the class II ban based on the 
de minimis environmental impact of such an exemption. Many of 
the products covered by the class II ban, particularly many 
of the foam products, release class II substances either during 
manufacture or disposal, rather than during use. While there 
are also cases where the class II substance is released in the 
use of the product, especially with the aerosol products, emissions

to the environment from these products, once manufactured, will 
be little or no different from the releases from these products 
if removed from commerce and subsequently disposed of. There 
are no proven destruction technologies for these products. Thus, 
where inventories already exist, subjecting products to the 
ban will have little environmental impact; the class II substances 
have already been released or would be released during disposal, 
if not released during use. In these circumstances, EPA believes 
it is appropriate to allow such products to be used for their 
intended purpose prior to disposal. 
   In addition, products otherwise subject to the class II ban 
have ozone-depleting potentials significantly lower than those 
of products subject to the class I ban, and EPA anticipates 
that smaller quantities of inventories should be on stock given 
the amount of time since the passage of the 1990 amendments 
to the Act. 
   EPA proposes that this exemption apply to all products placed 
into initial inventory as of ninety days from the date of
publication 
of this proposed rule. This would allow any product affected 
by this rule placed into initial inventory by the manufacturer 
(effectively manufactured) by December 27, 1993 to be sold and 
distributed, or offered for sale or distribution in interstate 
commerce after January 1, 1994. Manufactured means that the 
product is completed and placed into initial inventory. Any 
product placed into initial inventory after that date cannot 
be sold or distributed, or offered for sale or distribution 
in interstate commerce after January 1, 1994. EPA understands 
that prior to the publication of this NPRM, many manufacturers 
believed that their products would be entitled to an exemption 
and thus would not be covered by the ban, and such manufacturers 
therefore continued to manufacture new products. In addition, 
some producers believed that they could be granted exemptions 
based on worker safety or flammability concerns even though 
these products do not maintain a legal use of a class I substance. 
Under this proposal, the January 1, 1994 sales or distribution 
prohibition would not apply to any new products manufactured 
prior to December 27, 1993. However, the January 1, 1994 sales 
or distribution prohibition would apply to any new products 
manufactured after December 27, 1993. EPA believes that ninety 
days is an appropriate period to allow manufacturers to alter 
production capabilities. The legal authority for this type of 
exemption does not require or compel the Agency to include any 
time for the conversion of production capabilities; however, 
EPA is providing this time frame for the benefit of the
manufacturers. 
EPA requests comment on the feasibility for affected industries 
to switch over production capabilities within ninety days. 
   To continue selling products after January 1, 1994, the
manufacturer 
or distributor would need to show, upon request by EPA, that 
the product was in fact manufactured, and thus placed into initial 
inventory by December 27, 1993. Shipping forms, lot numbers, 
manufacturer date stamps or codes, invoices, or the like, may 
be used to identify the date the product was placed into initial 
inventory. EPA believes these types of records are normally 
kept by manufacturers and distributors of products affected 
by this proposed rule. 
   EPA believes that neither section 610(d) nor general principles 
of administrative law give the Agency the authority to consider 
any additional grandfathering options for existing inventories. 
However, EPA requests comment on its ability to grandfather 
under . 610(d). In addition, EPA requests comment identifying 
any barriers that might prevent retailers from liquidating stocks 
before the effective date. 
   b. Products Requiring Federal Approval Prior to Reformulation. 
EPA proposes to exempt from the class II ban those products 
requiring federal approval prior to reformulation, provided 
that manufacturers of such products have made a request of the 
appropriate federal agency for such federal approval prior to 
January 1, 1994. 
   EPA understands that it is sometimes a very time-consuming 
process to obtain federal approval for product reformulation. 
For instance, EPA approval for pesticide reformulations under 
the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) 
may take up to a year, and for example, Food and Drug
Administration 
approval for medical product reformulations may take several 
years. Where a manufacturer has made a timely request for the 
required federal approval, the timing of receipt of such approval 
is no longer in the control of the manufacturer. EPA does not 
believe it is appropriate for the federal government to effectively

deny manufacturers the ability to continue using current
formulations 
by subjecting them to the class II ban, while at the same time 
preventing them from reformulating pending receipt of any required 
federal approvals. 
   Alabama Power authorizes creation of administrative exemptions 
where necessary based on administrative feasibility. For example, 
EPA's FIFRA office and FDA have established administrative
procedures 
for processing FIFRA registrations and drug approvals,
respectively. 
The time frames associated with these processes represent the 
amount of time necessary for the federal agency to conduct a 
responsible review of the formulations and determine the
acceptability 
of the formulation under applicable statutes and regulations. 
The federal agencies cannot expedite their internal processing 
procedures simply because a formulation would otherwise be subject 
to the class II ban without compromising the integrity of their 
own program reviews. 
   EPA proposes allowing manufacturers that require federal 
approval for reformulations of a product or approval of a specific 
substitute product to continue to sell or distribute, or offer 
for sale or distribution in interstate commerce, their existing 
formulations until ninety days after receiving all appropriate 
federal agency approvals, providing the request for approval 
from the federal agency had been submitted by January 1, 1994. 
Therefore, for example, pesticides using class II substances 
could be sold or distributed after January 1, 1994, providing 
the product was manufactured before ninety days after the effective

date allowing FIFRA registration for the reformulated pesticide. 
Similar to the exemption provided above for existing inventories, 
EPA is proposing to allow the continued sale of existing
inventories 
of products manufactured through ninety days after the effective 
date of all appropriate federal approvals in order to allow 
sufficient time for the manufacturer to convert essential
facilities 
to the needs of the newly approved formulation. 
   EPA proposes allowing manufacturers that are denied federal 
approval for reformulations of a product or approval of a specific 
substitute product to continue to sell or distribute, or offer 
for sale or distribution in interstate commerce, their existing 
formulations until thirty days after receiving notice of denial 
from the federal agency. Consistent with the other temporary 
exemptions discussed in this section, products put into initial 
inventory by the manufacturer before thirty days after receipt 
of denial by the appropriate federal agency would be grandfathered.

Therefore, for example, if a pesticide using a class II substance 
is denied approval for reformulation from FIFRA, the product 
formulation containing the class II substance could be sold 
or distributed after January 1, 1994, providing the product 
was manufactured before thirty days after the receipt of denial. 
   Based on the time required to process federal approvals, 
EPA believes that it is necessary within the meaning of Alabama 
Power to provide a temporary exemption from the class II ban 
for products awaiting federal approval for reformulation, where 
manufacturers have applied for such approval prior to the effective

date of the final class II ban. 
   As discussed above, to continue selling after January 1, 
1994, the manufacturer or distributor would need to show that 
the pertinent federal approvals were applied for prior to January 
1, 1994 and that the product was in fact manufactured by ninety 
days following the receipt of all appropriate federal approvals. 

2. Scope of Interstate Commerce 

   EPA's interpretation of interstate commerce does not cover 
the sale, distribution, or offer of sale or distribution, of 
nonessential products within the boundaries of a single state. 
Thus, EPA believes that the Act does not ban the sale,
distribution, 
or offer of sale or distribution of a product otherwise affected 
by this rulemaking that is manufactured, distributed, and sold 
without ever crossing state lines. However, the Agency wishes 
to clearly state its position that to avoid coverage by this 
proposed rulemaking, an affected party must provide adequate 
documentation that not only was the product manufactured,
distributed, 
and/or sold exclusively within a particular state, but also 
that all of the components, equipment, and labor that went into 
manufacturing, distributing, selling, and/or offering to sell 
or distribute such a product originated within that state as 
well. The Agency wishes to further clarify that the sale of 
the product includes every sale up to and including the sale 
to the ultimate consumer, and that all these sales must take 
place without ever crossing a state line. Only in such
circumstances 
would a sale not be in interstate commerce. 

3. Resale of Used Products 

   EPA's interpretation of sale, distribution, or offer of sale 
or distribution in interstate commerce does not cover the resale 
of used products. Resale of used products means a sale, by a 
person after a period of use. The Agency recognizes that more 
than one consumer often derives utility from owning and using 
certain durable goods affected by this rulemaking, such as
automobiles 
and boats. Many of these products contain components manufactured 
out of integral skin foam, rigid foam, or semi-rigid foam.
Restricting 
the resale of such used durable goods before the end of their 
productive lifetimes would provide little, if any, environmental 
benefit, because the HCFCs used to blow foam for these products 
were effectively released into the environment during their 
manufacture or soon thereafter. Because restricting the resale 
of such used durable goods would impose significant economic 
hardship on a great many consumers without providing any associated

environmental benefits, EPA does not believe that Congress intended

to ban their resale. Consequently, while EPA's interpretation 
of ``interstate commerce'' is such that interstate commerce 
includes the entire chain of sale and distribution from the 
manufacturer of a new product to its ultimate consumer, the 
Agency recognizes that in the case of durable consumer goods 
such as boats and motor vehicles, resale of the product to
additional 
consumers may occur after the original sale of the new product 
to the ultimate consumer after some period of use. In such cases, 
EPA does not consider the resale of these banned products to 
constitute sale, distribution, or offer of sale or distribution, 
of a new product in interstate commerce for the purposes of 
this rulemaking. 

4. Imports and Exports 

   EPA believes that both the import of any product for sale 
or distribution within the United States, or the sale or
distribution 
of any product intended for ultimate export from the United 
States, are acts of interstate commerce within the meaning of 
section 610 and would, accordingly, be affected by this regulation.

The import or export of products affected by today's rulemaking 
would be subject to the same restrictions as the sale,
distribution, 
or offer of sale or distribution of these products in the United 
States. EPA will work in close cooperation with the U.S. Customs 
Service to enforce this restriction. Because today's proposed 
rulemaking would prohibit the sale, distribution, or offer of 
sale or distribution in interstate commerce of products banned 
pursuant to section 610(d), effective January 1, 1994, these 
products may continue to be imported, or sold or distributed 
for export, on or before January 1, 1994, the effective date 
of section 610(d). 

5. The Use of Affected Products Purchased Before the Effective 
Date of the Ban 

   During the rulemaking for the Class I Nonessential Products 
Ban, there was some confusion over the use of nonessential products

after the effective date(s) of the prohibition(s) on their sale, 
distribution, or offer of sale or distribution in interstate 
commerce. Consequently, in the final rulemaking for the class 
I ban, EPA confirmed that nonessential products purchased before 
the effective date may still be used, and that the Agency is 
not regulating the use of nonessential products, merely their 
sale and distribution as authorized by the statutory language 
(58 FR 4782). Section 610 of the Act does not address the use 
of products which are determined to be nonessential; the use 
of nonessential products purchased prior to the effective dates 
for the nonessential products ban is not subject to any
restrictions 
under section 610, although other laws and regulations regarding 
the release of ozone-depleting substances may apply to such 
use. 

B. Products Affected by the Class II Ban on Nonessential Products 

   The prohibition on the sale and distribution of nonessential 
products containing or manufactured with class II substances 
required by section 610(d)(1) is limited to those products
specified 
by the statute. Unlike the section 610(b) ban on products releasing

chlorofluorocarbons, the statute does not authorize EPA to identify

additional products that meet statutory criteria for
nonessentiality. 
Consequently, the products affected by this rulemaking are clearly 
specified in the statute. 
   The statute bans any aerosol product or pressurized dispenser 
that contains a class II substance and any plastic foam product 
which contains, or is manufactured with, a class II substance. 
As stated above, the statute exempts ``foam insulation products'' 
and ``integral skin, rigid, and semi-rigid foam utilized to 
provide for motor vehicle safety in accordance with Federal 
Motor Vehicle Safety Standards where no adequate substitute 
substance (other than a class I or class II substance) is
practicable 
for effectively meeting such Standards.'' In addition, EPA is 
authorized to grant exceptions for aerosol products and pressurized

dispensers that it determines to be essential as a result of 
flammability or worker safety concerns and where the ``only 
available alternative to [the] use of a class II substance is 
[the] use of a class I substance which legally could be substituted

for such class II substance.'' Consequently, EPA's role in this 
rulemaking is limited to identifying foam insulating products, 
determining whether adequate substitute substances are available 
for HCFCs in the production of integral skin, rigid, and semi-
rigid foams in motor vehicles, and granting exceptions for aerosol 
products which meet the criteria set out in the statute. The 
following sections discuss the affected products. 

1. Aerosol Products and Pressurized Dispensers Containing HCFCs 

   Section 610(d) bans the sale of all aerosol products and 
pressurized dispensers containing class II substances not
specifically 
excepted by the EPA under section 610(d)(2). The following section 
discusses the products affected by this provision. 
   In the course of the rulemaking to establish the Class I 
Nonessential Products Ban, questions were raised about the scope 
of the phrase ``aerosol product or other pressurized dispenser.'' 
This phrase could be interpreted as applying to pressurized 
containers (``bulk containers'') used to distribute materials 
for use in other products because these materials generally 
are self-pressurized when so contained. Such an interpretation 
would have had a devastating and unintended impact on the air-
conditioning and refrigeration industry. 
   The final rulemaking for the Class I Nonessential Products 
Ban clarified EPA's interpretation of this language (58 FR 4790). 
EPA believes that the phrase ``aerosol product or other pressurized

dispenser'' was meant to include non-aerosol products such as 
CFC-12 dusters and freeze sprays. However, the Agency does not 
believe that the term ``other pressured dispenser'' applies 
to pressurized containment vessels such as small containers 
of motor vehicle refrigerant or containment vessels for recycled, 
recovered or reclaimed refrigerant. Under EPA's interpretation, 
the phrase ``aerosol products or pressurized dispenser'' does 
not include bulk containers which are used solely for the
transportation 
or storage of controlled substances. As described in 40 CFR 
82.3(i) and the July 30, 1992 final rule implementing section 
604 and related provisions of sections 603, 607, and 616 of 
the Act (57 FR 33754), a ``controlled substance means any substance

listed in appendix A or appendix B to [subpart A] whether existing 
alone or in a mixture, but excluding any such substance or mixture 
that is in a manufactured product other than a container used 
for transportation or storage of the substance or mixture'' 
(57 FR 33788). A bulk container, also described in 40 CFR 82.3(i), 
means a container in which ``a listed substance or mixture must 
first be transferred [from, and then transferred] to another 
container, vessel, or piece of equipment in order to realize 
[the controlled substance's] intended use'' (57 FR 33788). 
   The products that EPA proposes to exempt in this NPRM are 
actually product categories rather than particular products 
manufactured and marketed by individual companies. In this
rulemaking, 
EPA is relying upon the definition of ``product'' developed 
in the Class I Nonessential Products Ban rulemaking. EPA reiterates

its belief that in section 610 of the statute, Congress applied 
this term to any type or category of merchandise or commodity 
offered for sale, as well as any use of an ozone-depleting
substance 
in the manufacture or packaging of any such merchandise or
commodity. 
Consequently, when granting exceptions, EPA intends to take 
action with regard to entire product categories rather than 
individual products in this rulemaking (EPA recognizes that 
in the case of certain niche markets, there may be only one 
individual product that falls within a particular category; 
in such a case, EPA will consider an exception for that specific 
product if it receives comments to that effect). 
   EPA believes that such an approach is appropriate, and that 
it is justified by the statutory treatment of certain groups 
of products manufactured with or containing class II substances 
in section 610(d). Congress banned entire categories of products 
in section 610(d)(2) when it banned aerosols, pressurized
dispensers, 
and plastic foam products containing class II substances, and 
exempted a category in section 610(d)(3)(A) when it exempted 
foam insulation products. EPA believes that the statutory language 
of section 610(d) indicates Congressional intent to address 
products and the use of ozone-depleting substances by broad 
use categories, provided that some mechanism exists for addressing 
particular applications within those categories which may meet 
the statutory criteria for exceptions or exemptions. EPA will 
carefully consider requests for exceptions and exemptions received 
during the public comment period in order to address additional 
foam or aerosol products which may meet the criteria for exceptions

and exemptions set out in the statute. EPA believes that this 
approach is equitable and comprehensive, and that it represents 
the most effective use of the Agency's resources.
   a. Previous Regulation Affecting the Use of HCFCs in Aerosol 
Products. In the past, CFCs were used extensively in aerosol 
products worldwide, mainly as propellants, but also as solvents 
and diluents, and as the active ingredients in some products. 
In the mid-1970s, the use of CFC-11 and -12 in aerosols accounted 
for 60 percent of the total use of these chemicals worldwide. 
As a result, on March 17, 1978, the EPA promulgated regulations 
under the Toxic Substances Control Act to ban the use of CFCs 
as aerosol propellants in most products (43 FR 11318). 
   The 1978 aerosol ban prohibited the manufacture or sale of 
aerosol products using CFCs as propellants. Other uses of CFCs 
in aerosols, such as solvents, active ingredients, or sole
ingredients, 
were not included in the ban. In addition, certain ``essential 
uses'' of CFCs as aerosol propellants were exempted from the 
ban because no adequate substitutes were available at the time. 
Consequently, although the use of CFCs in aerosols was reduced 
dramatically by the 1978 ban, the production of a number of 
specific aerosol products containing CFCs remained legal.{4} 
      ³  {4}  Those uses exempted or excluded from the 1978 
      ³ban included: metered dose inhalant drugs;
contraceptive 
      ³vaginal foam; lubricants for the production of
pharmaceutical 
      ³tablets; medical solvents such as bandage adhesives and

      ³adhesive removers; skin chillers for medical purposes; 
      ³aerosol tire inflators; mold release agents;
lubricants, 
      ³coatings, and cleaning fluids for
industrial/institutional 
      ³applications to electronic or electrical equipment;
special-
      ³use pesticides; aerosols for the maintenance and
operation 
      ³of aircraft; aerosols necessary for the military
preparedness 
      ³of the United States of America (primarily pesticides, 
      ³aircraft and electronics maintenance products, and
specialty 
      ³lubricants); diamond grit spray; single ingredient
dusters, 
      ³freeze sprays, and noise horns; mercaptan stench
warning 
      ³devices; pressurized drain openers; aerosol
polyurethane 
      ³foam dispensers; and whipped topping stabilizers. Many 
      ³of these exemptions were subsequently included in the 
      ³Class I Nonessential Products Ban. 
   Due to the 1978 ban on the use of CFCs as aerosol propellants 
in most products, consumption of CFCs by the aerosol industry 
in the United States decreased dramatically; in 1988, for example, 
only 9870 metric tons of CFCs were used in aerosols (primarily 
those products exempted or excluded from the 1978 ban),
representing 
approximately 2.5 percent of all class I substances (weighted 
by ozone-depletion potential) that year. U.S. formulators of 
aerosol products responded to the ban by switching to alternatives 
to CFCs, especially hydrocarbons and compressed gases such as 
CO2. However, in a number of applications, especially those 
where flammability is a concern, manufacturers have turned to 
HCFCs as substitute propellants and solvents. 
   In its Class I Nonessential Products Ban rulemaking, EPA 
re-examined all of the products excluded from the 1978 ban, 
as well as those specifically exempted from the 1978 ban. EPA 
also examined products identified by commenters to the proposed 
rule. A great deal of information was available to EPA in
promulgating 
the class I ban, including the Agency's 1989 report Alternative 
Formulations to Reduce CFC Use in U.S. Exempted and Excluded 
Aerosol Products, and the UNEP Technical Options Committee report 
on aerosols, sterilants and miscellaneous uses of CFCs.
   EPA determined that a number of alternative propellants and 
delivery systems have been developed and adopted since the original

aerosol exemptions were granted. As a result, many previously 
exempted or excluded products no longer used CFCs. Consequently, 
EPA concluded that satisfactory substitutes were available for 
most uses of CFCs in aerosols and pressurized dispensers. As 
a result of its research and the public comments received in 
response to its January 16, 1992 NPRM, EPA banned both propellant 
and non-propellant uses of CFCs in most aerosol products, exempting

only eleven specific applications for which it determined that 
no adequate substitutes for CFCs were available at that time.{5} 
      ³  {5}  The exempted products consisted of: medical
devices 
      ³listed in 21 CFR 2.125(e); lubricants for
pharmaceutical 
      ³and tablet manufacture; gauze bandage adhesives and
adhesive 
      ³removers; topical anesthetic and vapocoolant products; 
      ³lubricants, coatings or cleaning fluids for electrical 
      ³or electronic equipment, which contain CFC-11, CFC-12, 
      ³or CFC-113 for solvent purposes, but which contain no 
      ³other CFCs; lubricants, coatings or cleaning fluids
used 
      ³for aircraft maintenance, which contain CFC-11 or CFC-
      ³113 but which contain no other CFCs; mold release
agents 
      ³used in the production of plastic and elastomeric
materials, 
      ³which contain CFC-11 or CFC-113 but which contain no 
      ³other CFCs; spinnerette lubricant/cleaning sprays used 
      ³in the production of synthetic fibers, which contain 
      ³CFC-114 but which contain no other CFCs; containers of 
      ³class II substances used as halogen ion sources in
plasma 
      ³etching; document preservation sprays which contain
CFC-
      ³113 but which contain no other CFCs; and red pepper
bear 
      ³repellent sprays which contain CFC-113 but which
contain 
      ³no other CFCs. The majority of these applications were 
      ³for solvent applications of CFC-11 or CFC-113.
   b. Current Use of HCFCs in Aerosol Products. Today, aerosols 
and pressurized dispensers containing HCFCs make up only a small 
percentage of existing aerosol products. HCFCs have been available 
for industrial applications since the 1940s. However, until 
recently, they have not been used in large quantities in aerosol 
applications, primarily because in the past the cost of HCFCs 
was significantly higher than that of the most widely used
alternatives, 
CFCs and hydrocarbons. In recent years, with the imposition 
of an excise tax on CFCs and the establishment of an international 
agreement to phase out CFC production, HCFC use in aerosol products

and pressurized dispensers has increased. According to EPA
research, 
about 12 million pounds of HCFCs were used in 1991 in aerosol 
products and pressurized dispensers (mostly HCFC-22 used as 
propellant).
   There are several possible reasons that manufacturers of 
aerosol products and pressurized dispensers have refrained from 
using HCFCs in their formulations. Many industry representatives 
have informed EPA that manufacturers have been reluctant to 
convert to HCFCs because they believed that as ozone-depleting 
substances, these chemicals would be subject to additional
regulation 
in the future. In fact, the accelerated phaseout of the production 
proposed for HCFC-141b, HCFC-142b, and HCFC-22 would effectively 
limit the amount of time that manufacturers could use those 
HCFCs. In addition, awareness of the section 610(d) ban on the 
use of HCFCs in aerosol products and pressurized dispensers 
has encouraged formulators to explore other alternatives to 
HCFCs. As a result, EPA anticipates minimal future economic 
impact resulting from the statutory limitations on producers 
of aerosols and other pressurized dispensers containing HCFCs 
under section 610(d).
   EPA believes that a diverse group of companies are affected 
by this ban, including both small and large businesses. The 
small businesses may include manufacturers of products containing 
class II substances and retailers that sell these products. 
Based on numerous discussions, EPA believes these affected products

often represent a small fraction of the businesses' overall 
product line. EPA believes that larger companies also produce 
products containing HCFCs, especially foam products. EPA believes 
that many of these large businesses produce a wide assortment 
of other products not affected by the class II ban. EPA requests 
comment on the numbers and types of firms affected by this ban, 
and whether these companies have product lines that contain 
other products not affected by the ban.
   c. Alternatives to CFC and HCFC Use in Aerosol Products. 
EPA believes that manufacturers have been working to identify 
substitutes for HCFCs in all of their product areas. Currently 
available substitutes for aerosols and other pressurized dispensers

containing HCFCs include: hydrocarbons (predominantly propane 
and butane); other higher priced/special use flammable gases 
(dimethyl ether and HFC-152a); nonflammable compressed gases 
(such as carbon dioxide, nitrogen, nitrous oxide, and HFC-134a); 
solvent substitutes (methylene chloride and dimethyl ether/water 
mixtures); non-aerosol spray dispensers (finger pumps, trigger 
pumps, and mechanical pressure dispensers); and non-spray
dispensers 
(solid sticks, roll-ons, brushes, pads, shakers, and powders). 
The background document on aerosol products and pressurized 
dispensers containing class II substances, prepared in support 
of this rulemaking, discusses alternatives to HCFCs in aerosol 
applications in greater detail. 
   EPA does not necessarily advocate all of the substitutes 
currently being used by manufacturers in place of HCFCs. There 
are a number of safety and health issues associated with some 
of the possible substitutes for HCFCs in aerosol products and 
other pressurized dispensers; however, EPA believes that with 
the proper precautions, each of these alternatives could be 
used safely. EPA intends to carefully examine the issue of safe 
alternatives under its regulations to implement section 612.
   d. Exceptions for Aerosol Products and Pressurized Dispensers. 
Under section 610(d)(2), a particular aerosol or pressurized 
dispenser product containing a class II substance may be granted 
an exception from the ban by EPA if the Agency makes two
determinations: 
first, that it is essential as a result of worker safety or 
flammability concerns; and, second, that the only available 
alternative is a class I substance. Unless EPA determines that 
the product meets both these criteria and grants an exception, 
the aerosol or pressurized dispenser product is banned by section 
610(d). EPA has made an extensive survey of aerosol products 
and pressurized dispensers, and has identified the products 
that it believes qualify for exceptions under section 610(d)(2). 
EPA will carefully consider requests for additional exceptions 
received during the public comment period for aerosol products 
and pressurized dispensers to determine whether they meet the 
criteria laid out in section 610(d)(2).
   Section 610(d)(2)(A) requires that, in order to grant an 
exception to the ban, the Agency must determine that the aerosol 
product or pressurized dispenser is essential as a result of 
flammability or worker safety concerns. EPA interprets this 
requirement to mean that if the product is important (i.e., 
if it is not ``nonessential''), and if no substitute product 
or manufacturing process adequately (i.e., effectively) addresses 
issues of flammability and worker safety, then for the purposes 
of section 610(d)(2)(A), the use of a class II substance in 
that product is worthy of being considered essential.
   A second criterion must also be satisfied for granting an 
exception. Section 610(d)(2)(B) requires that, in order to grant 
an exception to the ban, the Agency must also determine that 
``the only available alternative to [the] use of a class II 
substance [in the product in question] is [the] use of a class 
I substance which legally could be substituted for such class 
II substance.'' Consequently, under section 610(d)(2), the Agency 
cannot grant an exception unless a class I substance could still 
be legally substituted for the class II substance that the product 
contains, even if EPA determines that an aerosol product or 
pressurized dispenser is otherwise worthy of being considered 
essential in accordance with section 610(d)(2)(A). The statute 
is clear in this regard. Both criteria must be met; the economic 
importance of a certain product or the health and environmental 
impacts associated with banning it are not by themselves sufficient

grounds for granting an exception. EPA believes that this situation

effectively limits the universe of products eligible for exceptions

to the class II statutory ban to those aerosol products and 
pressurized dispensers exempted from the Class I Nonessential 
Products Ban, and possibly products containing methyl chloroform, 
carbon tetrachloride, and halons, that is, those products still 
legally able to use class I substances. Research conducted for 
the Class I Nonessential Products Ban has led EPA to believe 
that adequate substitutes for all other aerosol products and 
pressurized dispensers containing HCFCs do, in fact, exist.{6} 
Eleven products (or solvent uses of CFCs in these products) 
were exempted under the Class I Nonessential Products Ban (58 
FR 4767). These products are listed below:
      ³  {6}  EPA has not at this time identified satisfactory

      ³substitutes for the products which, in its January 15, 
      ³1993 rulemaking, the Agency exempted from the ban on 
      ³aerosols and other pressurized dispensers containing 
      ³CFCs; however, EPA believes that due to recent
technological 
      ³advances, adequate substitutes for some of the
applications 
      ³exempted in the class I ban may soon be available.
These 
      ³same aerosol products and pressurized dispensers are 
      ³being considered for class II exceptions under this
proposal. 
      ³EPA may reconsider class I and class II exemptions for 
      ³these products, if at some time in the future, EPA
determines 
      ³that adequate substitutes are available.
i. Medical devices listed in 21 CFR 2.125(e)
ii. Lubricants for pharmaceutical and tablet manufacture
iii. Gauze bandage adhesives and adhesive removers
iv. Topical anesthetic and vapocoolant products
v. Solvent uses in lubricants, coatings or cleaning fluids for 
    electrical or electronic equipment
vi. Solvent uses in lubricants, coatings or cleaning fluids 
    used for aircraft maintenance
vii. Solvent uses in mold release agents
viii. Solvent uses in spinnerette lubricant/cleaning sprays
ix. Plasma etching
x. Solvent uses in document preservation sprays
xi. Solvent uses in red pepper bear repellent sprays
   Therefore, in order to grant an exception to the ban, the 
only available alterative to the use of the class II substance 
must be a legal use of a class I substance (as listed above) 
and the Agency must determine that the aerosol product or
pressurized 
dispenser is essential as a result of flammability or worker 
safety concerns. Consequently, EPA believes it is limited to 
considering granting exceptions under section 610(d)(2) only 
to the eleven products (or solvent uses of HCFCs in these products)

exempted under the Class I Nonessential Products Ban (58 FR 
4767).
   EPA realizes that the class II exemptions are integrally 
linked to the Class I Nonessential Products Ban. EPA believes 
the class I ban and the Act gave fair and ample notice to the 
public, and through the class I rulemaking process, addressed 
all of the comments received by the Agency. EPA realizes that 
there are a number of products that do not use class I substances, 
but do use class II substances. Some of the manufacturers of 
these products may not have commented on the need for a class 
I exemption, because they were not aware of the integral nature 
of the two bans (e.g. that class II exemptions could only be 
obtained where class I use was legal). As stated above, without 
a legal class I use, the Agency does not have authority under 
. 610(d) to grant exemptions under the class II ban. For the 
most part, aerosol products were only given exemptions under 
the class I ban for solvent uses. The Agency believes that
substitutes 
for all propellent uses of class I and class II products are 
currently available. If EPA were to determine, based on comments 
submitted under today's action, that there is a need to revise 
the Class I Nonessential Products Ban, EPA would likely consider 
only products for which the availability of substitutes was 
not sufficiently considered in the earlier rulemaking. The Agency 
requests comment on the need to revisit the Class I Nonessential 
Products Ban through this rulemaking with respect to any product 
for which there is no substitute for class II use other than 
a class I use which is no longer legal.
   Recently, EPA has been approached by the manufacturers of 
a product that may not have been sufficiently considered during 
the class I rulemaking, that being pesticides used in aircraft. 
Aircraft entering the United States from certain locations are 
required to eliminate foreign insects that might pose a threat 
to domestic agriculture or the population's health. In order 
to prevent accidentally transporting these insects, pesticide 
sprays are often used thirty minutes prior to landing in the 
United States. The unique need to apply this product during 
flight requires that formulations meet stringent specifications, 
including those regarding flammability, established by the
Department 
of Transportation and the Department of Agriculture. Pesticides 
used to disinfect aircraft may be using class I or class II 
substances. Currently, the Agency does not have enough information 
to determine whether EPA needs to revise the class I ban to 
provide an exception for this product. However, EPA requests 
comment on the need to revise the Class I Nonessential Products 
Ban to provide an exception for pesticides used on aircraft, 
with the intent that the class I substances not actually be 
used. The class I exception would merely provide the basis upon 
which to grant a class II exception, where no other acceptable 
alternatives are available. In addition, EPA is requesting comment 
on worker safety or flammability concerns regarding the use 
of substitutes for class II substances that may be used or
considered 
for use in aircraft pesticides.
   EPA has also recently received information about a second 
product that may not have been sufficiently considered during 
the class I rulemaking. This information concerns the manufacturing

and use of antispatter products used by welders. Either CFC-
113 or HCFC-141b may be used in antispatter products that are 
used as coatings to prevent the adhesion of weld spatter to 
metal surfaces. While methylene chloride may be a substitute 
for the class I and class II substances in this product, because 
welders often work in small work areas, with welding curtains 
that may interfere with ventilation systems surrounding their 
welding operation, welders could be exposed to high concentrations 
of methylene chloride. The particular formulations of the
antispatter 
products that contain class I and class II substances are the 
same formulations as some lubricants used for aircraft maintenance,

electronic and electrical equipment, and the same formulation 
as mold release agents. EPA granted a class I exception and 
is proposing to grant exceptions to the class II ban for the 
solvent uses of HCFCs in mold release agents and solvent uses 
in lubricants, coatings and cleaning fluids used for electronic 
and electrical equipment and aircraft maintenance. Currently, 
the Agency does not have enough information to determine whether 
EPA needs to revise the class I ban to provide an exception 
for antispatter products used by welders. However, EPA requests 
comment on the need to revise the Class I Nonessential Products 
Ban to provide a potential exception for antispatter products 
used by welders, with the intent that the class I substances 
not actually be used. The class I exception would merely provide 
the basis upon which to grant a class II exception, where no 
other acceptable alternatives are available. In addition, EPA 
is requesting comment on worker safety or flammability concerns 
regarding the use of substitutes for class II substances that 
may be used or considered for use as an antispatter product 
used by welders.
   Several manufacturers concerned about the availability and 
economic feasibility of using alternatives in other circumstances 
have also contacted EPA. In particular, manufacturers of dusters 
and safety sprays have commented on the possible need for a 
class I exception based on the unavailability of alternatives. 
EPA requests comment on the need to revise the Class I Nonessential

Products Ban to provide a potential exception for these products. 
In addition, EPA is requesting comment on worker safety or
flammability 
concerns regarding the use of substitutes for class II substances 
that may be used or considered for use in dusters and safety 
sprays. 
   The Agency believes it also has the authority to consider 
granting exceptions for products containing one or more class 
II substances and to respond to requests for exceptions to the 
ban based on the grounds that the only available alternative 
for the class II substance(s) is methyl chloroform or carbon 
tetrachloride (legally available class I substances). A
manufacturer, 
distributor, or retailer of a product containing one or more 
class II substances could request, during the comment period, 
an exception from EPA, citing methyl chloroform or carbon
tetrachloride 
as the only alternative(s). EPA would consider such a request, 
but the Agency would require significant proof that such claims 
were not attempts to circumvent the intent of the ban. Moreover, 
given that methyl chloroform and carbon tetrachloride are not 
suitable for use as propellants in aerosol products, EPA would 
be concerned about a request for an exception in which the
applicant 
claimed that the only available substitute for a propellant 
in its product was methyl chloroform or carbon tetrachloride, 
or that the HCFC-22 (generally used as a propellant) in its 
product served as a solvent.
   The Agency recently learned of a product, a pesticide used 
to kill wasps and hornets nesting near high-voltage power lines, 
that may require an exception based on the solvent use of HCFC-
141b in a new formulation, replacing the current formulation 
that uses methyl chloroform. EPA currently does not have enough 
information to determine if worker safety or flammability concerns 
relate to the use of alternatives to the class II substances, 
other than methyl chloroform, in wasp and hornet sprays.
Furthermore, 
EPA does not yet have confirmation that an application for new 
formulations has been submitted under the Federal Insecticide, 
Fungicide and Rodenticide Act (FIFRA) for these HCFC-formulations. 
Therefore, the Agency is not proposing to exempt the use of 
class II substances in wasp and hornet sprays used near high-
voltage power lines under today's proposed rulemaking. However, 
EPA requests comment on worker safety or flammability concerns 
regarding the manufacturing and use of these products, as well 
as comment on current and potential uses of class II substances 
in these products. In addition, EPA requests comment on whether 
the only available alternative to the use of a class II substance 
in wasp and hornet pesticides used near high-voltage power lines 
is the use of a class I substance.
   EPA also recently learned of another product in which
manufacturers 
may be using or considering using class II substances to replace 
the use of methyl chloroform. This aerosol product is used to 
clean hydraulic and electronic parts in aircraft, automotive 
and marine maintenance. In the class I rulemaking, EPA exempted 
the solvent uses of CFCs in lubricants, coating and cleaning 
fluids for electrical or electronic equipment and aircraft
maintenance. 
As discussed below, EPA is proposing to exempt the solvent uses 
of class II substances for these same products. However, this 
exemption does not apply to products used for hydraulic parts 
maintenance. EPA does not have enough information to determine 
if products used to clean hydraulic equipment meet all of the 
criteria for granting an exemption under section 610(d); therefore,

EPA is not proposing to exempt these products. However, EPA 
requests comment on worker safety or flammability concerns
regarding 
the manufacturing and use of these products, as well as comment 
on current and potential uses of class II substances in these 
products. In addition, EPA requests comment on whether the only 
available alternative to the use of a class II substance in 
hydraulic parts cleaners is the use of a class I substance.
   EPA is unaware of any other products for which manufacturers, 
distributors or retailers are substituting or planning to
substitute 
class II substances, because the only legal substitute for the 
class II substance is methyl chloroform or carbon tetrachloride; 
however, EPA is requesting comment on the need to grant exceptions 
based on worker safety or flammability considerations associated 
with such substitutes for class II substances.
   EPA notes that a number of the exemptions for aerosol products 
contained in the Class I Nonessential Products Ban final rule 
(58 FR 4767) were only for the use of particular CFCs as solvents 
in those products. The reason EPA specifically exempted those 
CFCs in the affected products is because EPA research indicated 
that while substitutes were available for CFCs as propellants 
in those products, the Agency had not determined that there 
were adequate substitutes available for the solvent uses of 
the specified CFCs in those products. CFC-11 and CFC-113 are 
used as solvents in a number of aerosol applications. CFC-12 
and CFC-114 are used primarily as propellants in aerosol
applications, 
but EPA granted requests for exemptions for several products 
containing CFC-12 and CFC-114 as solvents in the class I ban 
after receiving information indicating that no adequate substitutes

were currently available for the solvent, diluent, or carrier 
function that these CFCs served in these products. Consequently, 
EPA granted exemptions for the use of these CFCs in the specified 
products in the belief that this limited CFC use in these products 
represents the only legitimate solvent applications. Consequently, 
the Agency believes that there are no remaining legal propellant 
applications of CFCs in these products. As a result, EPA believes 
that it now only has the authority to exempt solvent applications 
of HCFCs in the products exempted in the class I ban final rule, 
since it is only for those applications that a class I substance 
could legally be used, one of the criteria for an exemption 
under the class II ban. The language in today's proposed regulation

reflects that belief.
   These products, as well as other products that may contain 
class II substances, are discussed below and at greater length 
in the background document accompanying this NPRM. EPA will 
carefully consider requests for additional exceptions received 
during the public comment period for aerosol products and
pressurized 
dispensers to determine whether they meet the criteria laid 
out in section 610(d)(2).{7}
      ³  {7}  The Agency will also consider removing
particular 
      ³aerosol products from the list of exempted products in 
      ³40 CFR 82.66(d)(2), as part of the final rule, if it 
      ³receives any such requests during the public comment 
      ³period for this rulemaking, documenting that such
products 
      ³do not meet the criteria for exemptions in section
610(d)(2).
   i. Medical devices listed in 21 CFR 2.125(e). Section 610(e) 
of the Act states ``nothing in this section shall apply to any 
medical device as defined in section 601(8).'' Section 601(8) 
defines ``medical device'' as any device (as defined in the 
Federal Food, Drug, and Cosmetic Act (21 U.S.C. 321)), diagnostic 
drug product (as defined in the Federal Food, Drug, and Cosmetic 
Act), and drug delivery system-(A) if such device, product, 
drug, or drug delivery system utilizes a Class I or Class II 
substance for which no safe and effective alternative has been 
developed and, where necessary, approved by the Commissioner 
of the Food and Drug Administration (FDA); and (B) if such device, 
product, drug, or drug delivery system, has, after notice and 
opportunity for public comment, been approved and determined 
to be essential by the Commissioner in consultation with the 
Administrator.
   FDA currently lists 12 medical devices for human use as
essential 
uses of CFCs in 21 CFR 2.125. These devices consist of certain 
metered dose inhalers (MDIs), contraceptive vaginal foams,
intrarectal 
hydrocortisone acetate, polymyxin B sulfate-bacitracin-zinc-
neomycin sulfate soluble antibiotic powder without excipients 
for topical use, and anesthetic drugs for topical use on accessible

mucous membranes where a cannula is used for application.
   FDA is currently reviewing medical devices using class II 
substances and if necessary, will revise 21 CFR 2.125 to reflect 
the class II ban. FDA plans to complete its review prior to 
the effective date of 610(d). EPA proposes, in accordance with 
section 610(e), exempting only medical devices identified as 
essential by FDA in 21 CFR 2.125 or otherwise identified as 
essential by FDA in accordance with section 601(8). These FDA 
``essential'' determinations are for the purposes of the class 
II ban only, and are not necessarily reflective of any other 
essential use determinations for other Title VI rulemakings.
   ii. Lubricants for pharmaceutical and tablet manufacture. 
Aerosol lubricants are used to coat mold chambers and punch 
presses used in the production of pharmaceutical pills and tablets.

These products typically contain class I substances. Because 
these products are used in the production of tablets and pills 
for human ingestion, they must be nonflammable and nontoxic. 
Since lubricants in the manufacture of tablets and pills are 
applied continuously in the manufacturing process, flammable 
or toxic alternatives present a greater risk to workers of exposure

to toxic fumes or explosion. Heat may build up on the pill presses 
and the continual use of the product may lead to appreciable 
vapor concentrations.
   Currently, the Agency is unaware of any class II users; however,

EPA believes that HCFC-22, and a blend containing HCFC-22 and 
HCFC-142b, are possible substitutes for the CFC-12 used in these 
lubricants. The Agency has no information on the use, planned 
use, or testing of HCFCs as substitutes for the use of CFC-113 
as a solvent. Therefore, EPA is not proposing to exempt the 
use of a class II substance in an aerosol lubricant for
pharmaceutical 
and tablet manufacturing under today's proposed rulemaking. 
However, EPA requests comment on worker safety or flammability 
concerns regarding the lubricants for pharmaceutical and tablet 
manufacture, and current and potential uses of class II substances 
in these lubricants.
   iii. Gauze bandage adhesives and adhesive removers. Adhesives 
are used by medical professionals to affix gauze bandages to 
the skin. Adhesive removers are used to facilitate removal of 
gauze bandages affixed with adhesive. EPA does not know of any 
manufacturers currently using HCFCs in these products. EPA is 
aware that alternative formulations of products used in medical 
applications require FDA approval. However, alternative products 
such as tincture of benzoin, that can be applied with sponge 
or cotton applicators, are available. These products help make 
the skin tacky and an adhesive remover is not generally required 
for bandage removal. However, they may be volatile and have 
an unpleasant odor.
   EPA currently does not have enough information to determine 
if worker safety or flammability concerns relating to the use 
of alternatives to class II substances in gauze bandage adhesives 
and adhesive removers exist. Therefore, the Agency is not proposing

to exempt the use of class II substances in gauze bandage adhesives

and adhesive removers under today's proposed rulemaking. However, 
EPA requests comment on worker safety or flammability concerns 
regarding the manufacturing and use of these products, as well 
as comment on current and potential uses of class II substances 
in these products.
   iv. Topical anesthetic and vapocoolant. Topical anesthetic 
and vapocoolant products are used by medical personnel to
temporarily 
deaden the response of nerves in the skin prior to minor topical 
operations. These products have also been used on fingers to 
facilitate the removal of tight rings. While the Agency is unaware 
of any manufacturers using class II substances in these products, 
EPA believes some formulations including HCFC-22 and HCFC-142b 
are possible. Preliminary research also points to HFC-134a as 
a potential substitute. In addition, nonpressurized substitutes, 
such as Novocaine administered by injection, are currently
available.
   EPA is currently unaware of any worker safety or flammability 
concerns relating to the manufacture or use of topical anesthetic 
and vapocoolant products. Therefore, the Agency is not proposing 
to exempt the use of class II substances in topical anesthetic 
and vapocoolant products in today's proposed rulemaking. However, 
EPA requests comment on worker safety or flammability concerns 
regarding the manufacturing and use of these products with
alternatives 
to class II substances, as well as comment on current and potential

uses of class II substances and HFC-134a in these products.
   v. Solvent uses in lubricants, coatings or cleaning fluids 
for electrical or electronic equipment. Lubricants help reduce 
friction and abrasion at points of contact between materials. 
Aerosol lubricants, which can be applied in a variety of forms, 
afford efficient, accurate application of the lubricant. Lubricants

include a wide range of products used in various applications, 
including cleaner-lubricants that provides a thin protective 
layer of lubrication while removing moisture, dust, dirt and 
oxidative products. Methyl chloroform, CFC-11, CFC-113, and 
to a lesser degree CFC-12, have traditionally been used as solvents

in aerosol lubricants, especially in applications where
flammability 
is a concern. Recently, there has been some replacement of the 
class I substances with HCFC-141b. However, EPA has not been 
able to determine the extent of this replacement, or determine 
any variations in effectiveness. The use of CFC-11, CFC-12 and 
CFC-113 as solvents in commercial aerosol lubricants for electronic

equipment was exempted from the ban on nonessential products 
containing class I substances.
   The use of lubricants in confined spaces or around sources 
of ignition could result in explosion if the product were
flammable. 
Although increased ventilation could help reduce the risk of 
flammability, failure of ventilation systems could pose an
immediate 
threat of fire or explosion. Therefore, the Agency believes 
flammability is a concern associated with the use of aerosol 
lubricants for electrical or electronic equipment.
   The aerosol solvent cleaners referred to here are primarily 
used in the manufacture, maintenance, and repair of electronic 
components and equipment. Aerosol solvent cleaners are typically 
used in hand cleaning or on-site maintenance operations that 
do not lend themselves to automated processes. In the electronics 
industry, aerosol solvent cleaners are often used for the manual 
defluxing of soldered electronic components.
   The active solvent ingredient in aerosol cleaning sprays 
is typically CFC-113. Other substances, including methyl chloroform

and CFC-11 are also used in solvents. The use of CFC-11 and 
CFC-113 in solvent cleaning fluids for electrical and electronic 
equipment is exempted from the class I ban on nonessential
products. 
Since HCFC-141b has properties similar to CFC-113, it has already 
found limited uses as a replacement for CFC-113.
   Aerosol solvent cleaners are often used at work benches in 
industrial situations. Flammability is a concern in such
environments. 
In addition, aerosol solvent cleaners may be used on electronic 
or electrical equipment that must be serviced while electrical 
current is turned on. Therefore, the Agency believes flammability 
is a concern associated with the use of aerosol cleaners for 
electrical or electronic equipment.
   EPA proposes exempting from today's proposed rulemaking the 
class II solvent uses in lubricants, coatings or cleaning fluids 
used for electrical or electronic equipment. However, the Agency 
requests comment on worker safety or flammability concerns
regarding 
the use of substitutes for class II substances as solvents in 
lubricants, coatings, aerosol cleaners for electrical or electronic

equipment, as well as comment on current and potential uses 
of class II substances. In addition, EPA requests comment on 
the need to exempt class II substances used in lubricants,
coatings, 
aerosol cleaners for electrical or electronic equipment that 
can only substitute a class II substance with methyl chloroform 
or carbon tetrachloride.
   vi. Solvent uses in lubricants, coatings or cleaning fluids 
used for aircraft maintenance. Aerosol lubricants are used on 
motors, wheel bearings, flight control cables, and other parts 
in the aircraft that are difficult to access and therefore
difficult 
to lubricate without a spray product. Class I substances are 
typically used as the solvents in these products.
   Aerosol cleaners are used to remove dirt, dust, and oxidative 
products from electronics components, such as contact switches, 
gears, and gauges in repair work or during aircraft operations. 
Typically, electric current will be running through these devices, 
or the power will be turned off and on to identify the faulty 
components. CFC-113 is frequently used as the solvent in these 
products. EPA believes HCFC-141b is being used as a substitute 
for CFC-113, to a limited degree. (More detailed information 
can be found in the Background Document on Aerosol Products 
and Pressurized Dispensers Containing Class II Substances.)
   There are safety concerns regarding the use of aerosol products 
for aircraft maintenance, primarily associated with the risk 
of flammability. The use of flammable or toxic products in the 
fuselage could prove hazardous because of the lack of ventilation. 
The use of cleaners or lubricants in this confined space could 
lead to an accumulation of flammable fumes and an increased 
risk of explosion. Therefore, the Agency believes flammability 
is a concern associated with solvent uses of class II substances 
in lubricants, coatings or cleaning fluids used for aircraft 
maintenance.
   EPA proposes exempting from the class II ban solvent uses 
in lubricants, coatings or cleaning fluids used for aircraft 
maintenance. However, the Agency requests comment on worker 
safety or flammability concerns regarding the use of substitutes 
for class II substances as solvents in lubricants, coatings, 
aerosol cleaners for aircraft maintenance, as well as comment 
on current and potential uses of class II substances.
   vii. Solvent uses in mold release agents. Aerosol mold release 
agents are sprayed onto industrial molds to facilitate the removal 
of molded products. Molded products can be made from metals, 
plastics, or rubber materials. For almost all applications, 
the release agent must be highly pure to prevent product
contamination 
and must be compatible with the substance being molded. 
   Manufactures of mold releases traditionally used CFC-11, 
CFC-12 and CFC-113. EPA exempted the use of CFC-11 and CFC-113 
from the ban on class I nonessential products due to the lack 
of available alternatives. Research to date indicates that there 
has been some substitution and extensive testing of HCFC-141b 
for CFC-113 as a solvent in mold release agents. HCFC-141b is 
believed to be an adequate substitute in this application, and 
thus, may be under consideration for more widespread substitution 
by manufacturers. 
   In general, mold release agents are applied to molds during 
the manufacture of plastics, medical products, rubber products, 
metals, and other products. Periods between application can 
be as short as 10 to 15 seconds. As a result, the build-up of 
flammable gases can become explosive in an industrial setting. 
Due to the nature of the product and its application, EPA believes 
worker safety and flammability concerns exist. Therefore, EPA 
proposes exempting from today's proposed rulemaking the class 
II solvent uses of in mold release agents. However, EPA requests 
comment on worker safety or flammability concerns regarding 
the use of a substitute for class II substances as solvents 
in mold release agents, as well as comment on current and potential

uses of class II substances. 
   viii. Solvent uses in spinnerette lubricant/cleaning sprays. 
During the production of certain synthetic fibers such as acrylic, 
a silicone product is sprayed onto spinning blocks called
spinnerettes 
to both clean and lubricate the machine. Traditionally, CFC-
114 has been the preferred solvent because it is nonflammable, 
nontoxic, and provides adequate dispersion of the active
ingredient. 
HCFC-22 and HCFC-142b are currently being used and are being 
considered for more extensive future use in this product. EPA 
is aware that alternatives to class I and class II substances, 
such as compressed air sprays, are being tested; however, EPA 
is not aware of any successful results stemming from these tests. 
Flammability is a concern for alternative formulations of this 
product because of the high surface temperature of the spinnerettes

(approximately 280c). The operator is usually no more than a 
few feet away while the lubricant is being sprayed. Due to the 
nature of the product and its application, EPA believes worker 
safety and flammability concerns exist. Therefore, EPA proposes 
exempting from today's proposed rulemaking the solvent uses 
of class II substances in spinnerette lubricants and cleaning 
sprays. However, EPA requests comment on worker safety or
flammability 
concerns regarding the use of a substitute for class II substances 
as solvents in spinnerette lubricants and cleaning sprays, as 
well as comment on current and potential uses of class II
substances. 
   ix. Plasma etching. During the manufacture of semiconductors, 
one step in the process requires the ``sub-micron etching'' 
of circuit lines on a thin slice of silicon crystal. This process 
technology, referred to as plasma or dry etching, uses various 
chlorine and fluorine-containing chemicals within a sealed chamber.

Radio frequency energy is supplied to the chamber and excites 
the chemicals, breaking them down into their component parts 
to create a chemical ``ion-plasma.'' This plasma (containing 
chlorine/or fluorine) is used to remove or etch parts of the 
silicon wafer. The ozone-depleting chemicals in this case are 
the vehicles which supply the halogen ions to the plasma. EPA 
is not aware of any manufacturers currently using class II
substances 
in plasma etching devices. Furthermore, the Agency is unaware 
of any worker safety or flammability concerns relating to the 
possible use of a substitute for a class II substance in a plasma 
etching device. Therefore, the Agency is not proposing to exempt 
plasma etching. However, the Agency requests comment on worker 
safety or flammability concerns regarding the use of a substitute 
for class II substances in plasma etching devices, as well as 
comment on current and potential uses of class II substances. 
   In addition, the Agency has received comments about whether 
plasma etching devices should be considered pressurized dispensers.

While EPA currently does not have enough information to make 
this determination, EPA believes that it is likely that plasma 
etching devices do not meet the definition of pressurized
dispensers. 
The language in section 610 did not restrict EPA to considering 
only aerosol products and pressurized dispensers in determining 
the essential nature of the products using class I substances. 
However, EPA did limit the types of products considered, in 
part to be consistent with the class II ban. During the development

and promulgation of the class I ban, EPA believed that plasma 
etching devices were pressurized dispensers. However, EPA has 
subsequently received additional information as to the nature 
of plasma etching devices. Consequently, the Agency requests 
comment on whether plasma etching devices should be considered 
pressurized dispensers. 
   x. Solvent uses in document preservation sprays. Books,
documents, 
and works of art on paper can be preserved through the application 
of a nonaqueous deacidification technology. There are several 
technologies currently being used. EPA is aware of several
formulations 
which include the use of a class II substance as a propellant. 
However, non-HCFC propellants, such as carbon dioxide and nitrogen,

are currently being used in aerosol document preservation sprays, 
and thus, constitute alternatives to HCFC-22 used in this
application. 
In addition, pump sprays bottles are available alternatives. 
Moreover, EPA is limited to only considering the exempted uses 
of a class I substance in granting exceptions to the class II 
ban. Therefore, EPA can only consider the solvent use of a class 
I substance. EPA does not have enough information to determine 
if worker safety or flammability concerns relating to the solvent 
use of class II alternatives in document preservation sprays 
exist. Therefore, the Agency proposes not exempting solvent 
uses of class II substances in document preservation sprays 
under today's rulemaking. However, the Agency requests comment 
on worker safety or flammability concerns regarding the use 
of a substitute for a class II substances as solvents in document 
preservation sprays, as well as comment on current and potential 
uses of class II substances. 
   xi. Solvent uses in red pepper bear repellent sprays. The 
nature of red pepper bear repellent sprays makes an aerosol 
formulation particularly useful as the user of a bear repellent 
needs the product to deliver the repellant instantaneously without 
perfect aim. CFC-113 use in red pepper bear repellant sprays 
was exempted under the class I ban. During the development of 
the class I ban, one manufacturer specifically indicated that 
HCFC-141b, as well as any other potential substitute, would 
not be adequate in its formulation, because the CFC imparts 
characteristics to the defensive spray that are critical to 
its effectiveness against bears.{8} EPA is unaware of any
manufacturers 
using a class II substance as a solvent in the formulation of 
red pepper bear repellent sprays. Furthermore, EPA does not 
have enough information to determine if worker safety or
flammability 
concerns relating to the solvent use of an alternative to a 
class II substance in red pepper bear repellent sprays exist. 
Therefore, the Agency is not proposing to exempt solvent uses 
of class II substances in red pepper bear repellent sprays in 
today's rulemaking. However, the Agency requests comment on 
worker safety or flammability concerns regarding the use of 
a substitute for class II substances as solvents in red pepper 
bear repellents, as well as comment on current and potential 
uses of class II substances.

      ³repellents can be found in the Background Document on 
      ³Aerosol Products and Pressurized Dispensers Containing 
      ³Class II Substances. 
   e. Verification and Public Notice Requirements for Cleaning 
Fluids for Non-Commercial Electronic and Photographic Equipment. 
Section 610(b)(2) required EPA to ban the sale of
chlorofluorocarbon-
containing cleaning fluids for electronic and photographic
equipment 
to non-commercial users. EPA estimates that non-commercial sales 
of such fluids represent a small fraction of the total use of 
these products. Nevertheless, the statute specifically required 
EPA to ban the sale of these products containing CFCs for non-
commercial use. Consequently, EPA proposed, and the final rule 
included, a ban on the sale, distribution, or offer of sale 
or distribution of these products to non-commercial users. As 
a result of this statutory mandate, there is no remaining
chlorofluorocarbon 
which legally could be substituted for class II substances in 
non-commercial cleaning fluids for electronic and photographic 
equipment. 
   Aerosol cleaning fluids for electronic and photographic
equipment 
sold to commercial users are often used at work benches in
industrial 
situations. Flammability is a concern in such environments. 
In addition, these cleaning fluids may be used on electronic 
or electrical equipment that must be serviced while electrical 
current is turned on. Therefore, the Agency believes flammability 
is a concern associated with the use of aerosol cleaning fluids 
for electronic and photographic equipment. 
   Accordingly, today's proposed rule would ban the sale of 
aerosol cleaning fluids for electronic and photographic equipment 
containing class II substances to non-commercial users. The 
Agency wishes to clarify that under section 610(d), unlike under 
section 610(b), EPA is restricted to considering only aerosol 
cleaning fluids. 
   It is possible that certain cleaning fluids for electronic 
and photographic equipment may contain methyl chloroform or 
carbon tetrachloride. The use of either of these ozone-depleting 
substances in aerosol products was not prohibited under the 
class I ban; consequently, such cleaning fluid products containing 
methyl chloroform or carbon tetrachloride are not restricted 
under the class I ban. A manufacturer, distributor, or retailer 
of a cleaning fluid product containing one or more class II 
substances could request an exception by EPA through this
rulemaking, 
by indicating during the comment period that the only available 
alternative for the class II substance(s) contained in its product 
was methyl chloroform or carbon tetrachloride. EPA would consider 
such a request if the situation arose, but the Agency would 
require documentation that such claims were not attempts to 
circumvent the intent of the ban. Moreover, methyl chloroform 
and carbon tetrachloride are not suitable for use as propellants 
in aerosol products. 
   In the Class I Nonessential Products Ban, EPA eliminated 
specific recordkeeping requirements proposed in the NPRM. The 
Agency agreed with the commenters that such requirements would 
be too burdensome when compared to the limited associated
environmental 
benefits. Instead of requiring distributors to maintain detailed 
records of transactions involving CFC-containing cleaning fluids, 
the final rule merely required sellers and distributors to post 
signs stating that sale, distribution, or offer of sale or
distribution, 
in interstate commerce of these products to non-commercial users 
is prohibited and that purchasers of these products must provide 
verification that they are commercial users. In addition, sellers 
and distributors were required to verify that purchasers of 
these products are commercial users. In order to purchase these 
products, commercial users would have to prove that they are 
indeed commercial entities. Purchasers could fulfill this
requirement 
by presenting any number of existing documents generally issued 
to commercial entities as a condition for conducting business. 
Sellers and distributors would have to have a reasonable basis 
for believing that the information presented by the purchaser 
is accurate and thus that the purchaser is in fact a commercial 
user. These documents could include a federal employer
identification 
number, a state tax exemption number, a local business license 
number and a government contract number. EPA believes that these 
requirements impose the least burden while still meeting the 
statutory requirement to prevent non-commercial users from
purchasing 
CFC-containing cleaning fluids. 
   EPA believes that the statutory language in section 610(d) 
compels the Agency to adopt similar verification provisions 
with regard to cleaning fluids containing class II substances. 
Consequently, today's proposed rule contains verification and 
public notice requirements similar to those in the class I ban 
final rule. EPA has already been informed by one distributor 
of such cleaning fluids for which it intends to extend its
verification 
procedures to products containing class II substances as of 
January 1, 1994. 

2. Plastic Foam Products Produced With HCFCs 

   Section 610(d) prohibits the sale, distribution, or offer 
of sale or distribution in interstate commerce of all plastic 
foam products which contain, or are manufactured with, class 
II substances, and which are not specifically excluded from 
the ban under section 610(d)(3), as of January 1, 1994. Certain 
types of plastic foam products, specifically foam insulation 
products and integral skin, rigid, or semi-rigid foams necessary 
to meet the Federal Motor Vehicle Safety Standards, are excluded 
from the ban by the statute. However, in this rulemaking, EPA 
must determine which plastic foam products qualify as ``foam 
insulation products,'' and whether adequate substitutes for 
certain HCFC-blown foams are practicable for effectively meeting 
the Federal Motor Vehicle Safety Standards. The following section 
discusses the products affected by this provision. 
   For the purposes of this rulemaking, EPA interprets the term 
``plastic foam product'' to mean any product (as defined in 
40 CFR 82.62) composed in whole or in part of material that 
can be described as ``foam plastic'' or ``plastic foam.'' EPA 
interprets ``foam plastic'' or ``plastic foam'' to mean a type 
of plastic such as polyurethane or polystyrene which has been 
produced using blowing agents to create bubbles or ``cells'' 
in the material's structure. 
   The foam plastics manufacturing industries, the markets their 
products serve, and their uses of CFCs and HCFCs are extremely 
varied. CFC-11, CFC-12, CFC-113, CFC-114, HCFC-22, HCFC-141b, 
and HCFC-142b have all been used to some extent as blowing agents 
in the manufacture of plastic foam products, which include building

and appliance insulation, cushioning foams, packaging materials, 
floatation devices and shoe soles. 
   There are two basic types of foam produced with halocarbons: 
thermosetting foams and thermoplastic foams. In the production 
of thermosetting foams, a blowing agent is mixed with chemicals 
which react to form the plastic foam product. With thermoplastic 
foams, the blowing agent is injected into a molten plastic resin 
which hardens upon cooling. 
   An important distinction exists between foam plastics where 
the cells are closed, trapping the blowing agent inside, and 
those with open cells which release the blowing agent during 
the manufacturing process. The gas trapped in closed cell foams 
can, if it possesses a low thermal conductivity, provide
significant 
thermal insulation. All of the foam products used as thermal 
insulation are closed cell foams. Open cell foams are not good 
thermal insulators. 
   CFCs had been commonly used as blowing agents in the
manufacturing 
process of many foam products because they have suitable boiling 
points and vapor pressures, low toxicity, and very low thermal 
conductivity. In addition, they are non-flammable, non-reactive, 
and, until the imposition of the excise tax on ozone-depleting 
substances, they had been very cost-effective. The excise tax 
levied by Congress in 1989 significantly raised the cost of 
CFCs to foam manufacturers (except for the manufacture of rigid 
insulating foam, which was exempt from the tax in 1990 and is 
subject to a greatly reduced tax of approximately $0.25 per 
pound until 1994). As a result, foam manufacturers have switched 
to non-CFC substitutes in many areas. Among the many commonly 
used substitutes for CFCs in foam production are HCFCs, CO2, 
hydrocarbons and methylene chloride. In addition, HFCs and
fluorinated 
ethers may offer long-term substitutes for plastic foam production.

   According to the 1991 UNEP Flexible and Rigid Foams Technical 
Options Report, global CFC consumption in foam production decreased

by roughly 35 percent between 1986 and 1990. EPA believes that 
the level of CFC use in the U.S. for many foam types has
experienced 
a similar dramatic decrease since 1986. For some foam products, 
the use of CFCs has already been completely phased out. In many 
applications, especially foam thermal insulation products, HCFCs 
have replaced CFCs as blowing agents. 
   EPA examined the use of class I and class II substances in 
foam products for its section 610 rulemaking activity. In preparing

today's proposed rule, EPA relied heavily upon the research 
conducted for the 1991 UNEP Flexible and Rigid Foams Technical 
Options Report. Foam affected by today's rulemaking has been 
categorized in accordance with the methodology used in the UNEP 
reports on foams produced with ozone-depleting substances.{9} 
EPA's Class I Nonessential Products Ban rulemaking also relied 
heavily upon UNEP research. 
      ³  {9}  EPA participated in the development of the
definitions 
      ³of product categories utilized in the UNEP technical 
      ³options reports as part of the Montreal Protocol
process, 
      ³and the Agency routinely employs these categories in 
      ³its own reports, internal documents, and rulemakings. 
      ³Copies of this and other appropriate UNEP reports are 
      ³contained in the Air Docket A-93-20. 
   As part of the Montreal Protocol process, the United Nations 
Environment Programme Montreal Protocol Flexible and Rigid Foam 
Technical Options Committee was formed. This committee is comprised

of internationally respected experts nominated by national
governments 
to determine the technical and economic feasibility of halting 
the use of chemicals that destroy the ozone layer. The twenty 
members are selected primarily from industry and government 
research laboratories and represent Belgium, Canada, Germany, 
Japan, Switzerland, United Kingdom, and the United States. Members 
are employed by every major supplier of foaming chemicals and 
many high volume, sophisticated foam users, as well as by the 
associations representing suppliers and users. Reports are peer 
reviewed internationally and the conclusions are reached by 
consensus. 
   The 1989 and 1991 reports of the Foams Technical Options 
Committee were so credible and respected that they have been 
republished and relied upon extensively by various Parties. 
   The UNEP report identifies foam products that have significant 
thermal insulating properties (and which are used primarily 
in insulating applications) and those that do not (these foams 
are used mostly in packaging and cushioning applications, but 
some of them have incidental insulation applications as well). 
EPA refers to this latter category as ``flexible and packaging 
foams.'' EPA used the same categories in the section 610(b) 
rulemaking. 
   a. Ban on Nonessential Products Containing CFCs. Based on 
its research, the Agency prohibited the use of CFCs in flexible 
and packaging foams in the Class I Nonessential Products Ban. 
The Agency focused on these foam sectors due to the clear
availability 
of substitutes such as water-blown foam, reformulated foams, 
and alternative chemicals such as HCFC-22 and methylene chloride. 
EPA did not prohibit the use of CFCs in insulating foam, expanded 
polystyrene foam, polyvinyl chloride foam, or integral skin 
foam. The reasons for this decision are described below. 
   EPA did not include insulating foams manufactured with CFCs 
in the Class I Nonessential Products Ban. Although flexible 
and packaging foams have currently available substitutes, the 
UNEP technical options report estimated that the elimination 
of CFCs in insulating foams would not be technologically feasible 
until 1995 in developed countries. Moreover, Congress indicated 
its intent to facilitate the transition from CFC-blown insulation 
foam to alternatives. For example, rigid insulating foams using 
CFCs were exempt from the excise tax in 1990, and they are subject 
to a reduced tax until 1994.{10} In addition, the statutory 
ban on the use of class II substances in foam products in section 
610(d) specifically exempts insulating foams. Congress exempted 
foam insulation products from the section 610(d) ban without 
qualification, rather than exempting these products until adequate 
substitutes were available. EPA believes that research and
development 
currently underway will eventually result in the widespread 
use of alternatives to HCFCs as blowing agents in the manufacture 
of foam insulation products. 
      ³  {10}  The use of CFCs in insulating foams after 1995 
      ³is not an issue of concern to EPA in light of the
accelerated 
      ³phaseout schedule and the January 1, 1994 increases in 
      ³the excise tax on insulating foams produced with CFCs. 
   EPA also considered including integral skin foam in the Class 
I Nonessential Products Ban. Integral skin foam is used in a 
number of applications, including motor vehicle safety
applications, 
as indicated by section 610(d)(3)(B). EPA was not able to
conclusively 
determine in the time available for the class I ban rulemaking 
that adequate substitutes for integral skin foam, or for the 
use of CFCs in the production of integral skin foam, were
available. 
As a result, EPA did not include them in the class I nonessential 
products ban; however, the Agency reserved the right to take 
action under section 610 to prohibit the use of CFCs in integral 
skin foams at some future time, if necessary. 
   b. Current Use of HCFCs in Plastic Foam Production. EPA research

has identified seven types of plastic foam products that are 
currently being produced with HCFCs, and which consequently 
are affected by today's proposed rule:

i. Closed cell rigid polyurethane foam 
ii. Open cell flexible polyurethane foam 
iii. Integral skin polyurethane foam 
iv. Closed cell extruded polystyrene sheet foam 
v. Closed cell extruded polystyrene boardstock foam 
vi. Closed cell polyethylene foam 
vii. Closed cell polypropylene foam

   EPA is not aware of any other types of plastic foam being 
produced with HCFCs; however, if other types of foam (such as 
polyvinyl chloride foam, expanded polystyrene foam, open cell 
rigid polyurethane foam, or open cell flexible polyurethane 
molded foam) are being produced with HCFCs, the sale, distribution,

or offer of sale or distribution in interstate commerce of such 
plastic foam products will also be illegal after January 1, 
1994, unless EPA determines that they meet the conditions for 
exemption from this rulemaking under section 610(d)(3)(A) or 
610(d)(3)(B). EPA requests comment on any other types of foam 
that are being produced with HCFCs. 
   c. Plastic Foam Products Exempt from the Ban Under Section 
610(d). Section 610(d)(3) exempts ``foam insulation products'' 
and ``integral skin, rigid, and semi-rigid foam utilized to 
provide for motor vehicle safety in accordance with Federal 
Motor Vehicle Safety Standards where no adequate substitute 
substance (other than a class I or class II substance) is
practicable 
for effectively meeting such Standards.'' The following sections 
discuss the treatment of these products in EPA's proposed rule. 
   i. Foam Insulation Products. Section 610(d)(3) states that 
the ban on plastic foam products containing or manufactured 
with HCFCs shall not apply to ``foam insulation products.'' 
EPA identified two possible interpretations of this phrase. 
``Foam insulation products'' could be interpreted to mean products 
containing foam that are used for insulating some object. This 
phrase could also mean products containing ``insulating foam.'' 
   In addition, EPA considered different possible interpretations 
of the word ``insulation.'' The largest use of plastic foams 
produced with CFCs and HCFCs is in products that provide thermal 
insulation for buildings, equipment, and a host of different 
objects, but commenters suggested that the word ``insulation'' 
could also conceivably refer to a product or material that protects

or ``insulates'' some object from other phenomena, such as noise, 
shock, or electromagnetic radiation. Several private sources 
have suggested to EPA that the word ``insulation'' should be 
interpreted to mean a product or material that protects some 
object from physical impacts or vibration. EPA examined each 
of these options in preparing today's proposed rulemaking. 
   For the purposes of this rule, EPA proposes defining ``foam 
insulation product'' as any product containing the following 
materials: 
   (1) Closed cell rigid polyurethane foam, 
   (2) Closed cell rigid polystyrene boardstock foam, and 
   (3) Closed cell rigid phenolic foam. 
   In addition, EPA proposes to define pipe insulation made 
out of closed cell rigid polyethylene foam as a foam insulation 
product. 
   EPA believes that the word ``insulation'' should be interpreted 
to mean thermal insulation exclusively. The primary uses of 
plastic foam products consist of thermal insulation, cushioning, 
and packaging applications. As mentioned above, most CFCs and 
HCFCs currently used in foam production are used in the production 
of thermal insulation products. The remainder of foam products 
produced with CFCs and HCFCs are used primarily in the packaging 
of high-value products. The Montreal Protocol process, the work 
done by the UNEP Flexible and Rigid Foam Technical Options
Committee, 
and much of the technical literature about the foam industry 
reflects a distinction between foam thermal insulation products 
and foam products used primarily for producing cushioning and 
packaging material. Consequently, it seems likely that Congress 
adopted the same convention when drafting this legislation. 
   Because the statutory language is ambiguous, EPA has the 
authority to reach a reasonable interpretation of the definition 
of foam insulation. (See Chevron v. NRDC, 467 U.S. 837 (1984)). 
Reviewing the provisions of section 610 as a whole, EPA is
proposing 
that the exemption in section 610(d)(3)(A) should apply only 
to thermal insulation products. In section 610(d)(3), Congress 
provided two statutory exemptions, one for foam insulation and 
one for certain types of motor vehicle safety foam under specified 
circumstances. Under a broad interpretation of foam insulation 
including all insulating uses, such as physical shock or impact 
insulation, motor vehicle safety foams would be included in 
the definition of foam insulation, since motor vehicle safety 
foams serve to insulate vehicle occupants from crash impact. 
Therefore, the second exemption provided by Congress would be 
entirely unnecessary if the first exemption were broad enough 
to include the products covered by the second exemption.
Furthermore, 
it would not be necessary for Congress to limit motor vehicle 
safety foams to specific circumstances where substitutes were 
unavailable. A broad interpretation of the definition of foam 
insulation would exempt motor vehicle safety foams from the 
class II ban even where substitutes were easily available, contrary

to the explicit provisions of the second exemption. 
   Moreover, if EPA were to interpret the word ``insulation'' 
to include protection from noise, electromagnetic radiation, 
impact, or physical shock, this regulation would not in any 
way restrict the use of HCFCs in plastic foam production. The 
entire ban would be nullified by the exemption, since all foams 
insulate products from something. It is unlikely that Congress 
enacted a legislative provision intended to have no effect. 
EPA believes that it is complying with the intent of the statute 
in limiting the exemption for ``foam insulation products'' to 
foams that provide thermal insulation. The legislative intent 
of this language is discussed below. 
   EPA believes that Congress intended to exempt only foams 
used for thermal insulation in section 610(d)(3)(A), although 
Congressional intent with regard to the insulation products 
to be exempted is somewhat unclear. The Joint Explanatory Statement

of the Committee of Conference accompanying the Clean Air Act 
Amendments of 1990 provides no additional discussion of the 
scope of the word ``insulation'' in section 610(d); the only 
supplemental information regarding Congressional intent bearing 
directly on the definition of insulation of which EPA is aware 
is contained in the floor statement of Representative Ralph 
Hall (136 CR H12899). Other statements such as that of
Representative 
Walgren 136 CR H12938, the report of the Senate Committee on 
Environment and Public Works, Senate Report Number 101-228, 
101st Congress, 1st Session, page 397, and statements of Senate 
managers Baucus and Chafee (136 CR S16948), shed no additional 
light on Congressional intent. 
   EPA believes that additional support for interpreting foam 
insulation product as thermal insulation only can be found in 
the regulations published by the Internal Revenue Service (52 
FR 56303 and 26 CFR 52.4682) to implement the excise tax on 
ozone-depleting substances first established by Congress in 
the Omnibus Budget Reconciliation Act of 1989. In these
regulations, 
IRS defined ``rigid foam insulation'' as ``any rigid foam that 
is designed for use as thermal insulation.'' IRS defined ``rigid 
foam'' as any closed cell polymeric foam (whether or not rigid) 
in which chlorofluorocarbons are used to fill voids within the 
polymer.'' While the IRS definition of foam insulation is markedly 
different from the one proposed by EPA in today's rulemaking 
(as they were written with different statutory mandates and 
different implementation goals in mind), the IRS definition 
indicates that Congress intended to single out foam products 
on the basis of their thermal insulation properties, in
establishing 
the excise tax, and thus by analogy also in drafting 610(d).{11} 
As a result of its consideration of the legislative record and 
regulatory precedent, EPA believes that its interpretation of 
insulation as thermal insulation is appropriate. 
      ³  {11}  Some might suggest that EPA adopt the IRS
definition 
      ³of foam insulation product for this rulemaking. EPA
wishes 
      ³to point out that the IRS definition of rigid foam
insulation 
      ³only considers foam blown with CFCs and would result 
      ³in no exemption for any foam insulation product
containing 
      ³HCFCs unless they contained CFCs as well. 
   According to EPA research, and research conducted under the 
auspices of the United Nations Environment Programme, closed 
cell rigid polyurethane foam, closed cell rigid polystyrene 
boardstock foam, and closed cell rigid phenolic foam are the 
only types of plastic foam used primarily for their low thermal 
conductivity. One of the reasons that CFCs and HCFCs are used 
almost exclusively as blowing agents in thermal insulation
products, 
and the reason that EPA has not proposed including any open-
cell plastic foam products in the exemption for foam insulation 
products, is that foam thermal insulation products rely upon 
the low thermal conductivity of the gasses trapped within the 
foam cells to provide their thermal ``insulating'' properties. 
Closed cell rigid polyurethane foam, closed cell rigid polystyrene 
boardstock foam, and closed cell rigid phenolic foam are widely 
used in a great many thermal insulation applications. In addition, 
closed cell rigid polyethylene foam, although not used primarily 
for its thermal insulating properties, is widely used to provide 
thermal insulation around pipes in heating, plumbing,
refrigeration, 
and industrial process systems (this closed cell rigid polyethylene

foam insulation product is often referred to as ``pipe wrap''). 
Consequently, the Agency proposes defining these four categories 
of foam and foam products as ``foam insulation products'' for 
the purposes of the section 610(d) rulemaking because its research 
to date indicates that only these product categories constitute 
legitimate uses of HCFC-blown foam for thermal insulation
applications. 
   Webster's Dictionary defines to insulate as ``to separate 
from conducting bodies by means of nonconductors so as to prevent 
transfer of electricity, heat, or sound.'' EPA reviewed this 
definition, and considered defining a ``foam insulation product'' 
as any product made out of HCFC-blown foam that could meet the 
above definition by providing any degree of insulation, regardless 
of the type of HCFC-blown foam that it contained. However, in 
order to accurately determine which products could meet the 
definition, EPA would need to examine the ``end-use'' of every 
single product containing plastic foam produced with HCFCs in 
order to determine whether the HCFC-blown foam in that product 
served as an insulator against heat, electricity or sound. Products

that did not meet this definition would automatically be subject 
to the ban. This approach could complicate the rulemaking process 
and significantly increase cost for ensuring compliance with 
the class II ban, both for the affected businesses and the Agency. 
In light of the significant burden this would impose on both 
the industry and the administrative agency, and the Agency's 
interpretation of Congressional intent, EPA opted for proposing 
the definition of ``foam insulation product'' based on the research

conducted under the auspices of the United Nations Environmental 
Programme and described above. However, EPA requests comment 
on the use of this alternative definitions based on the end-
use of the product. 
   EPA recognizes that other interpretations of Congressional 
intent may exist. The conference substitute cited by Representative

Ralph Hall (136 CR H12899) in discussions of the Clean Act
Amendments 
on the House Floor includes the following discussion of section 
610(d): ``the conference substitute also does not prohibit
insulating 
foams made with class II compounds (which could include foams 
that are necessary for energy efficient building construction, 
appliances, or for the insulation of sensitive medical supplies 
and sensitive electronic components.)'' EPA notes that the
statement 
uses the words could include, not does include, indicating that 
not every foam used in these products should be exempted from 
the ban. Since certain medical supplies and electronic components 
are sensitive to extreme temperatures, as well as variations 
in temperature, EPA believes its interpretation of foam insulation 
as thermal is appropriate. However, as discussed above, EPA 
recognizes that it is possible to interpret the conference
substitute, 
and the definition of insulating foam differently. Other possible 
interpretations may require EPA to review the end-use of each 
foam product in order to determine if its use is consistent 
with Congressional intent. EPA requests comment on the use of 
alternative definition of insulating foams. 
   EPA recognizes that minor non-insulating uses exist for the 
foams that it proposes to exempt under section 610(d)(3)(A). 
However, EPA believes that by adopting the definition based 
on UNEP's work, the Agency will exempt all of the appropriate 
thermal insulation applications of plastic foam products produced 
with HCFCs, while at the same time, it will allow relatively 
few non-insulating uses of HCFCs in foam production to continue. 
While section 610(d) gives the Agency the authority to exempt 
``a foam insulating product,'' EPA does not believe the Agency 
has authority to regulate how products categorized as foam
insulating 
products are actually used. Moreover, the environmental impact 
of allowing the continued use of HCFCs in the exempted foam 
types for non-insulating end-use applications will be
insignificant, 
while additional restrictions on the sale, distribution, or 
offer of sale or distribution in interstate commerce of non-
insulation products containing these foam types would impose 
additional unnecessary burdens on businesses and the federal 
government without providing any appreciable environmental
benefit.{12}
      ³  {12}  Should the use of HCFCs in the production of 
      ³exempted foam products for non-insulating applications 
      ³increase significantly, the Agency might at some future

      ³date revise its definition as necessary to limit such 
      ³use. 
   EPA requests comment on its proposed definition of ``foam 
insulation product,'' and on other products or foam types that 
should be included in this definition based on their thermal 
insulating qualities. 
   EPA wishes to note that individuals or businesses that introduce

``foam insulation products'' containing or manufactured with 
class II substances into interstate commerce may be required 
to comply with labeling requirements of the Act if the
Administrator 
determines that adequate substitutes exist for those class II 
substances, and issues class II warning label regulations
accordingly. 
   ii. Specific Applications of Both Insulating and Noninsulating 
Foams. To help clarify how foam products would be treated under 
the proposed regulation, the following section provides specific 
examples. 

Closed Cell Polyurethane Foam Used as Flotation Foam 

   Closed cell polyurethane foam is used as a thermal insulating 
foam. However, it is also used for a number of non-insulation 
purposes. The largest non-insulation application of closed cell 
polyurethane foam is as flotation foam in the manufacture of 
certain boats. Coast Guard regulations (33 CFR subpart F 183.101) 
require that boats less than 26 feet in length meet certain 
flotation standards. Many small boat manufacturers use CFC- 
or HCFC-blown foam as both structural and flotation material 
in the manufacture of their boats in order to comply with these 
regulations. In the case of flotation foam, the thermal insulating 
properties of closed cell polyurethane foam are incidental to 
its use in this application. However, consistent with the Agency's 
proposed definition of a ``foam insulation product,'' EPA does 
not believe it has the authority to ban the use of a foam
insulation 
product, whether or not used for a non-insulating purpose. 
   Flotation foam serves as an important safety feature of many 
small watercraft. In addition, in at least one product line, 
closed cell polyurethane foam serves as a structural element 
as well. Several manufacturers of closed cell polyurethane
flotation 
foam have indicated that they have developed, and are marketing, 
foam-blowing systems that are CFC- and HCFC-free, and a number 
of boat manufacturers are already using halocarbon-free foam 
in their production lines. Other boat companies have indicated 
their intention to convert from CFCs and HCFCs to alternatives 
such as CO2 and HFC-134a in the near future. 
   EPA is proposing to define all products made out of closed 
cell rigid polyurethane foam, closed cell rigid polystyrene 
boardstock foam, and closed cell rigid phenolic foam, as well 
as pipe insulation made out of closed cell rigid polyethylene 
foam, as foam insulation products for the purposes of this
rulemaking. 
Consequently, closed cell rigid polyurethane foam used as flotation

foam, rather than as insulation, is exempt from the class II 
ban. EPA wishes to note, however, that the use of closed cell 
rigid polyurethane insulation foam as flotation foam may still 
be subject to the section 611 labeling requirement in the future. 
   EPA requests comments on the incidental inclusion of products 
not using insulating foam for its thermal qualities in the
exemption 
to the class II ban. 

Aerosol Polyurethane Foam 

   Aerosol polyurethane foam or rigid polyurethane foam dispensed 
from a pressurized packaging, also known as one-component foam, 
is used by both the building industry and by do-it-yourselfers 
in a variety of applications. These applications include draft-
proofing around pipes, cable runs, doors and windows; sealing 
doors and window frames; and joining together insulating panels, 
roofing boards, and pipe insulation. 
   CFC-12 has traditionally been the blowing agent of choice 
for aerosol foams because of its relatively low boiling point. 
CFC-12 in this product acts both as a propellant and as a blowing 
agent yielding ``frothed foam'' that does not flow away from 
the site of its application. In recent years, there has been 
widespread conversion away from CFC-12 and toward such alternatives

as HCFC-22 and hydrocarbons. 
   For the purposes of this rulemaking, aerosol foams will be 
treated as foams and not as aerosols. EPA believes that this 
approach is consistent with regulations published by the Internal 
Revenue Service (52 FR 56303) that treat spray foam as an
insulating 
foam product for tax purposes. In addition, the UNEP technical 
options report categorizes spray foam as foams not aerosols. 
Furthermore, this approach is consistent with EPA's treatment 
of aerosol foams in the Class I Nonessential Products Ban (58 
FR 4789). 
   While many manufacturers have converted from ozone-depleting 
substances to alternatives such as hydrocarbons, it is not clear 
that these substitutes are adequate for all applications at 
the present time. Hydrocarbons may pose flammability risks both 
at the point of manufacture and at the point of use. 
   Hydrocarbons, because of their flammability, may pose
significant 
risks to safety and health when used as propellants and blowing 
agents in aerosol foams. However, EPA is also concerned about 
the risks to human health and the environment posed by continued 
use of ozone-depleting substances in aerosol foams. The Agency's 
proposed definition of insulating foam does not consider the 
end use of the product. As a result, while the Agency believes 
alternatives that do not use class II substances can be used, 
the Agency does not have the authority under the proposed
definition 
to limit the end use of closed cell polyurethane. 
   EPA requests comments on the incidental inclusion in the 
exemption of products not using insulating foam for its thermal 
qualities. 

Closed Cell Extruded Polystyrene Sheet Foam 

   Closed cell extruded polystyrene sheet foam has been used 
extensively in the past in packaging for food products in grocery 
stores and fast food chains. Representatives of the food service 
and packaging industry have commented to EPA in the past that 
the primary function of polystyrene packaging such as cups, 
trays, ``clamshell'' containers, and plates in this application 
was one of containing food, not keeping the food hot or cold. 
Consequently, EPA does not consider closed cell extruded
polystyrene 
sheet foam an insulating foam.{13} EPA is not aware that any 
claims have ever been made about the thermal conductivity of 
extruded polystyrene sheet foam (such as the R-value of products 
manufactured with this foam). 
      ³  {13}  In fact, EPA defined polystyrene sheet foam as 
      ³a ``flexible and packaging foam'' and banned the sale, 
      ³distribution, or offer of sale or distribution in
interstate 
      ³commerce of polystyrene sheet foam containing or
manufactured 
      ³with CFCs in its Class I Nonessential Products Ban. 
   EPA notes that most producers of closed cell extruded
polystyrene 
sheet foam have converted their facilities to use hydrocarbons 
as the blowing agents in the production of this foam, and the 
Agency has been informed that the largest remaining user of 
HCFCs in closed cell extruded polystyrene sheet foam production 
plans to end its use of HCFCs in this process before the January 
1, 1994 deadline. Consequently, EPA believes that prohibiting 
the sale, distribution, or offer of sale or distribution in 
interstate commerce of closed cell extruded polystyrene sheet 
foam products containing or manufactured with HCFCs effective 
January 1, 1994 as required by . 610(d) will have little economic 
impact. 

Closed Cell Polyethylene Foam and Closed Cell Polypropylene 
Foam Sheet 

   EPA has received information about the use of closed cell 
polyethylene foam for the production of ``backer rods'' for 
the construction of buildings that employ a curtainwall and 
panel system for their outer shells. Joints between panels in 
these systems are closed with elastomeric sealants which are 
injected into the joints. ``Backer rods'' are used to limit 
the depth to which the sealants penetrate these joints. Outside 
sources have indicated that backer rods also provide an important 
insulation function in buildings constructed in this fashion. 
However, EPA research indicates that the primary ``insulating'' 
function of backer rods consists of protecting the building 
against moisture, e.g. condensation and leaking. EPA believes 
that this secondary function of backer rods, while important, 
does not require the use of ozone-depleting substances in foam 
production in this product. Moreover, EPA does not believe that 
backer rods provide significant thermal insulation for buildings 
constructed in this fashion. Consequently, EPA has not included 
closed cell polyethylene backer rods in its definition of foam 
insulation product in today's rulemaking, in light of its
interpretation 
that only thermal insulation is exempt from the class II ban, 
and because the use of class II substances to provide non-thermal 
insulation is not necessary. 
   One company in the U.S. makes extruded polypropylene foam. 
This company is in the process of converting its products to 
non-HCFC formulation, but it has expressed concern about the 
treatment of its existing inventory of products produced under 
the old process in this regulation. Most of this foam is used 
in packaging applications; however, some extruded polypropylene 
foam is ostensibly used as insulation in such applications as 
concrete curing and shrubbery covers. EPA believes that the 
``insulating'' function that this product provides in these 
applications consists of protecting the concrete or plants from 
a number of environmental phenomena, such as moisture and wind. 
EPA believes that any thermal insulation that the product provides 
in these applications is incidental and does not constitute 
thermal insulation within the intent of . 610(d). Consequently, 
EPA has not included any closed cell polypropylene foam products 
in its definition of foam insulation product in today's rulemaking.

EPA requests comment on the use of these products solely for 
their thermal capability. Furthermore, EPA requests comments 
on its treatment of all of the above foam products in today's 
proposed rule. 
   iii. Foam Used to Meet Federal Motor Vehicle Safety Standards. 
Section 610(d)(3) states that the ban on class II substances 
in plastic foam products shall not apply to any ``foam insulation 
product'' or ``an integral skin, rigid, or semi-rigid foam utilized

to provide for motor vehicle safety in accordance with Federal 
Motor Vehicle Safety Standards where no adequate substitute 
substance (other than a class I or class II substance) is
practicable 
for effectively meeting such Standards.'' 
   Section 103 of the National Traffic and Motor Vehicle Safety 
Act of 1966 authorized the National Highway Traffic Safety
Administration 
(NHTSA) to promulgate Federal Motor Vehicle Safety Standards, 
which have subsequently been published in 49 CFR part 571. The 
Federal Motor Vehicle Safety Standards are, for the most part, 
performance standards. The use of particular materials is generally

not specified in the standards in 49 CFR part 571 affected by 
this rulemaking. Consequently, to the best of the EPA's knowledge, 
no HCFC-blown foams are specifically required by the NHTSA
regulations. 
However, since the enactment of the laws requiring these standards 
beginning in the late 1960s, the motor vehicle manufacturing 
industry has relied almost exclusively on foams to meet the 
section 571 impact protection standards (the only exception 
EPA is aware of consists of leather-wrapped steering wheels 
and leather-covered dash boards, and the Agency understands 
that even these products have foam underneath). 
   After conducting its own research and consulting with officials 
at the NHTSA, the EPA believes that the use of HCFC-blown foams 
is not, or shortly will not, be necessary to meet the Federal 
Motor Vehicle Safety Standards. According to an industry source, 
all foams used in automotive applications except integral skin 
foams are currently produced without CFCs or HCFCs (these products 
are ``water-blown'' foams which use CO2 as the blowing agent). 
Consequently, in today's NPRM, EPA proposes exempting only the 
use of integral skin foam from the class II ban on plastic foam 
products. 
   Industry sources have indicated that the most difficult Federal 
Motor Vehicle Safety Standard for the automobile industry to 
meet without using CFCs or HCFCs involves impact protection 
padding on steering wheels. In addition, these sources have 
indicated that producing air bag module covers which meet the 
relevant standards without the use of CFCs or HCFCs is still 
a technological challenge. At this time, both products are usually 
made with integral skin foam produced with CFCs or HCFCs. Water-
blown foams are currently being tested, and EPA believes that 
in the near future water-blown integral skin foam will be
``practicable 
for effectively meeting'' the Federal Motor Vehicle Safety
Standards 
as specified under the statute. Industry sources indicate that 
HFC-134a is also being tested for use in this application, and 
that integral skin foam produced with HFC-134a should be available 
within three to four years. 
   EPA believes that testing to ensure that the substitutes 
for HCFC-blown integral skin foam meet the Federal Motor Vehicle 
Safety Standards must be complete before the Agency can determine 
that an adequate substitute for the use of an ozone-depleting 
substance is available that is practicable for effectively meeting 
these standards, as is required by section 610(d) before the 
class II ban will apply to these products. Industry sources 
are in some disagreement with regard to the time-frame in which 
substitutes for HCFC-blown foams will be available.{14} Information

from the NHTSA indicates that NHTSA believes that the necessary 
lead time for designing, testing, and producing new components 
to meet Federal Motor Vehicle Safety Standard regulations is 
typically 14 to 18 months, but may be up to 36 months when the 
changes are major. EPA anticipates that an adequate substitute 
substance, water-blown integral skin foam, will be available 
by January 1, 1996, that will be practicable for effectively 
meeting the relevant Federal Motor Vehicle Safety Standards 
for impact protection. EPA anticipates that another adequate 
substitute (HFC-134a) will be available before that date. 
      ³  {14}  Several industry representatives claimed that 
      ³several more years of testing are necessary to ensure 
      ³that the re-formulated components meet the Federal
Motor 
      ³Vehicle Safety Standards, and one U.S. company recently

      ³indicated that water-blown integral skin foam would be 
      ³available for these applications by model year 1995 or 
      ³1996. However, according to one source, a number of
European 
      ³auto manufacturers have adopted water-blown foam
already, 
      ³although EPA does not know whether the vehicles
produced 
      ³with this foam have been tested to determine whether 
      ³they meet the Federal Motor Vehicle Safety Standards. 
   Consequently, in today's rulemaking, EPA proposes applying 
the statutory ban on the sale, distribution, or offer of sale 
or distribution in interstate commerce to all foam components 
used in motor vehicles except those made out of integral skin 
foam and those which qualify as foam insulation products as 
defined in section 82.62(h) of today's NPRM, effective January 
1, 1994. EPA proposes exempting integral skin foam made with 
HCFCs under the provisions of section 610(d)(3)(B) from the 
class II ban on plastic foam products until January 1, 1996. 
At that time, the exemption for HCFC-blown integral skin foam 
will expire (or ``sunset''). In addition, EPA proposes to exempt 
existing inventories of integral skin products manufactured 
prior to January 1, 1996. 
   EPA recognizes that integral skin products necessary to meet 
Federal Motor Vehicle Safety Standards regulations may have 
been installed in automobiles prior to January 1, 1996; however, 
the automobiles may not have been sold prior to January 1, 1996. 
Automobile dealerships often use cars as demonstration models, 
offering the automobile for sale at a later date. Therefore, 
EPA does not believe it is practical to require these cars to 
be sold prior to January 1, 1996. Furthermore, there are no 
proven destruction technologies for integral skin foam products. 
Thus, where inventories already exist, subjecting products to 
the ban will have little environmental impact, as the class 
II substances have already been released or will be released 
during disposal, if not released during use. In these
circumstances, 
EPA believes it is appropriate to allow such products to be 
put to their intended purpose prior to disposal. 
   EPA will revisit the sunset provision for this exemption 
at a future date if the Agency receives a request from the public 
for extending the exemption. If upon subsequent investigation 
EPA determines that adequate substitutes will not be available 
by the January 1, 1996 date, the Agency will consider extending 
the exemption for an additional period of time as appropriate 
to allow development of adequate substitutes. 
   Because of the lead time necessary to design, test, and build 
automobile components, EPA has selected the sunset provision 
for integral skin foam in motor vehicles to include a January 
1, 1996 expiration date for this exemption. However, EPA wishes 
to note that individuals or businesses that introduce motor 
vehicles containing or manufactured with class II substances 
into interstate commerce may be required to comply with labeling 
requirements if the Administrator determines that there are 
substitutes for such substances and issues applicable class 
II warning label regulations in accordance with the provisions 
of 40 CFR part 82 subpart E until the sunset of this exemption. 
   iv. Foam Used in Medical Devices. Section 610(e) states that 
section 610 does not apply to any medical device as defined 
in section 601(8). In the Class I Nonessential Products Ban, 
all of the products identified that fit the definition of medical 
devices were aerosol products or other pressurized dispensers. 
It is conceivable, however, that certain foam products containing, 
or produced with, class II substances might qualify as medical 
devices. EPA is currently unaware of any such products, but 
recently the Agency has been contacted by businesses that produce 
foam cushions and wheelchair seats for disabled individuals 
from foam blown with HCFCs. According to these firms, these 
products are necessary to prevent disabled individuals from 
developing painful bedsores, and water-blown foams that have 
been tested have not proved satisfactory. 
   Under section 601(8), the Commissioner of the Food and Drug 
Administration, in consultation with the Administrator of the 
EPA, must determine that no safe and effective alternatives 
to the use of class I or class II substances in this product 
exist, and that such a product is essential before EPA can exclude 
it from coverage under section 610 as a medical device. If, 
at some time in the future, the products described above, or 
some other foam product is determined by the FDA to be essential, 
EPA will take appropriate action to exclude it from the class 
II ban. 

IV. Proposed Effective Dates 

   This proposed rule would make it unlawful to sell, distribute, 
or offer to sell or distribute, in interstate commerce the products

specifically mentioned in 40 CFR 82.70(a), 40 CFR 82.70(b) and 
40 CFR 82.70(c)(i) effective January 1, 1994. In addition, the 
proposed rule would ban the sale, distribution, or offer of 
sale or distribution, in interstate commerce of the products 
identified in 40 CFR 82.70(c)(ii) effective January 1, 1996. 

V. Summary of Supporting Analyses 


A. Executive Order 12291 

   Executive Order (E.O.) 12291 requires the preparation of 
a regulatory impact analysis for major rules, defined by the 
order as those likely to result in: 
   (1) An annual effect on the economy of $100 million or more; 
   (2) A major increase in costs or prices for consumers,
individual 
industries, Federal, State or local government agencies, or 
geographic industries; or 
   (3) Significant adverse effects on competition, employment, 
investment, productivity, innovation, or on the ability of United 
States-based enterprises to compete with foreign-based enterprises 
in domestic or export markets. 
   EPA has determined that this proposed regulation does not 
meet the definition of a major rule under E.O. 12291 and has 
therefore not prepared a formal regulatory impact analysis. 
EPA has instead prepared two background documents (see references 
Background Document on Foam Products Made With Class II Substances 
and Background Document on Aerosol Products and Pressurized 
Dispensers Containing Class II Substances in Docket A-93-20) 
which include a qualitative study of the economic impact of 
this proposed regulation for each product identified as
nonessential 
and prohibited from sale or distribution. 
   EPA believes that most foam is produced by large businesses. 
This is due to high entry barriers, including the need for large 
capital investments. However, the class II ban affects all the 
groups involved in the sale and distribution of the foam products; 
therefore, other entities besides the producers, including small 
businesses, are involved. In many cases, foam represents one 
component of a finished product that is produced by a small 
business. In addition, the finished products are often sold 
by small retail business operations. EPA has done initial research 
on the numbers and types of firms that manufacture and sell 
foam products affected by the class II ban, and on the potential 
economic impact the class II ban may have on these entities. 
   EPA believes that the class II ban will have no economic 
impact for the manufacturers of open cell rigid polyurethane 
foam, because EPA is not aware of any manufacturers of this 
product that use HCFCs. The class II ban is likely to have minimal 
impact on the manufacturers of flexible molded foam since EPA 
believes that most have moved directly from CFCs to methylene 
chloride and water formulations. Most of the production of semi-
rigid integral skin foam still relies on the use of halocarbon 
blowing agents. However, the exemption for foams used to meet 
automotive safety standards will significantly alleviate the 
impact the ban will have on these products. EPA believes that 
most other types of polyurethane foams are made with HCFCs. 
EPA believes that approximately 85 to 90 percent of extruded 
polystyrene sheet foam does not rely on HCFCs. Companies that 
use HCFCs will be required to switch blowing agents; thus, these 
companies will be impacted by the ban. EPA does not believe 
the ban will have any impact on polyethylene bead foam, since 
EPA believes the manufacturers of this product have already 
switched to hydrocarbons. EPA is aware of at least six extruded 
polyethylene manufacturers that have converted to hydrocarbons; 
however, some of the other producers of extruded polyethylene 
foam, not used as pipe wrap, will be significantly impacted. 
EPA believes the ban will have no impact on expanded polypropylene 
bead manufacturers since these manufacturers have converted 
to hydrocarbons. However, the sole American producer of extruded 
polypropylene may incur significant costs. Further details
concerning 
the preliminary qualitative results of this research appear 
in the Background Document on Foam Products Made With Class 
Substances. 
   Many manufacturers of aerosol products could be characterized 
as small businesses. EPA believes that few companies that primarily

manufacture aerosol products have more than 100 employees. However,

several facilities are actually part of larger companies that 
produce a range of other products. In both cases, the entire 
product line produced by the manufacturers may not consist of 
products containing class II substances. Distributors and retailers

may vary considerably in size and product line. EPA has done 
initial research on the numbers and types of firms that manufacture

and sell aerosol products and pressurized dispensers affected 
by the class II ban, and on the potential economic impact the 
class II ban may have on these entities. 
   EPA has examined a number of aerosol products affected by 
the class II ban. This research included both products that 
could meet the narrow criteria for receiving exceptions,
established 
by Congress in section 610(d), and those that do not meet the 
criteria. Much of the information collected by EPA is qualitative 
and anecdotal in nature. Examples of these findings are discussed 
below. 
   EPA is aware of formulations for document preservation sprays 
that do not use class I or class II substances. However, at 
least one major manufacturer is testing formulations using class 
II substances. Therefore, the class II ban may significantly 
impact this product. Many pesticide products using class II 
substances will be affected by the class II ban. However, the 
impacts will be reduced because of EPA's proposal to allow
manufacturers 
that require federal approval for reformulation for a product 
or approval of a specific substitute product to continue to 
sell or distribute, or offer for sale or distribution in interstate

commerce, their existing formulations until ninety days after 
receiving all appropriate federal agency approvals. The provision 
will also provide relief for other products requiring approval 
prior to reformulation. Manufacturers of dusters and freezants 
that have continued to use HCFC formulations will be affected 
by the class II ban; however, companies that have already moved 
to alternatives such as carbon dioxide or HFCs will not be
affected. 
Many manufacturers of defensive sprays also will be significantly 
impacted by the class II ban. Further details concerning
preliminary 
qualitative results of this research appears in the Background 
Document on Aerosol Products and Pressurized Dispensers Containing 
Class II Substances. 
   EPA has considered the benefits that can be attributed to 
the class II ban. In order to calculate the benefits, EPA
considered 
the total annual consumption of HCFCs in products that will 
be banned. EPA estimates that the annual HCFC consumption in 
foam products that will be banned is approximately 27.31 million 
pounds. The annual HCFC consumption in aerosol products that 
will be banned is approximately 11.8 million pounds. EPA attributes

all of the avoided emissions and corresponding benefits to the 
class II ban. EPA believes that if the self-executing ban was 
not included in the Clean Air Act Amendments the current amount 
of HCFCs used in the foam and aerosol sectors would have been 
greater. Furthermore, without the ban these annual emissions 
actually would continue to increase, especially during the next 
several years. These increases would have leveled off and only 
begun to decrease as the phaseout dates for HCFCs approached 
(2003-2030). EPA believes the benefits for this rule range between 
$148 million and $604 million when using a 2 percent discount 
rate, and between $107 million and $438 million when using a 
7 percent discount rate. 
   EPA requests comment on the overall benefits of the class 
II ban and the costs the class II ban will have on affected 
businesses. In particular, EPA requests comment on the size 
and diversity of the companies affected by the ban, the potential 
costs associated with the class II ban, and the impact the class 
II ban will have on small entities. In addition, EPA requests 
comment on the cost and benefits associated with these proposed 
regulations. Specifically, EPA requests comment on the offsetting 
beneficial effects that the proposed exceptions, grandfathering 
of existing inventories, and grandfathering for products waiting 
for required federal approvals, will have on affected businesses. 

B. Regulatory Flexibility Act 

   The Regulatory Flexibility Act, 5 U.S.C. 601-602, requires 
that Federal agencies examine the impacts of their regulations 
on small entities. Under 5 U.S.C. 604(a), whenever an agency 
is required to publish a general notice of proposed rulemaking, 
it must prepare and make available for public comment an initial 
regulatory flexibility analysis (RFA). Such an analysis is not 
required if the head of an agency certifies that a rule will 
not have a significant economic impact on a substantial number 
of small entities, pursuant to 5 U.S.C. 605(b). 
   EPA believes that any impact that this regulation will have 
on certain small entities is unavoidable given the straightforward 
nature of the statutory provision this regulation implements. 
A preliminary examination of the impacts on small entities is 
discussed in the background document accompanying this proposed 
regulation. The background document assesses the impact this 
regulation may have on small entities and provides examples 
of such impacts. In general, such impacts were found to be minimal.


C. Paperwork Reduction Act 

   Any information collection requirements in a proposed rule 
must be submitted for approval to the Office of Management and 
Budget (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 
et seq. Because no informational collection requirements are 
proposed in today's action, EPA has determined that the Paperwork 
Reduction Act does not apply to this proposed rulemaking and 
no Information Collection Request document has been prepared.
