 1998  Scientific Assessment  Reasserts
That Montreal  Protocol  is Working
...But Worst Ozone Depletion Still Lies Ahead
       igns of continuing success for the
       Montreal Protocol are evident in the
       atmosphere. This conclusion and oth-
       ers come from the 1998 Scientific
Assessment of Ozone Depletion, the most
recent of a series of comprehensive analyses
published jointly by the World Meteorological
Organization (WMO) and the United Nations
Environment Programme (UNEP).
  The report states that, "the total combined
abundance of ozone-depleting compounds in
the lower atmosphere peaked in about 1994
and is now slowly declining." Total concentra-
tions  of chlorine—the destructive atom released
from  chlorofluorocarbons (CFCs) in the atmos-
phere—are on the decline, but total bromine
concentrations—the even more destructive
atoms released from halons and methyl bro-
mide—are still increasing.
  There are delays,  however, in
the time it takes CFCs, halons,
and other ozone-depleting sub-
stances to pass from the lower
to the upper atmosphere
(stratosphere). The combined
abundance of stratospheric
chlorine and bromine is
expected to "peak before the
year 2000," meaning we
should expect the most
severe rates of ozone deple-
tion "to lie within the cur-
rent decade or the next
two decades," according
to the report.            7
  Sometime thereafter in the 21st century the
ozone layer is expected to begin recovering,
assuming, of course, continued compliance
with the Montreal Protocol. The authors of the
report say that, "unambiguous detection of the
beginning of the recovery of the -ozone layer is
expected to be well after the maximum loading
of ozone-depleting gases." This is because the
fall-off in stratospheric chlorine and bromine  .
abundance will be more gradual than the climb
to peak levels. Furthermore, ongoing changes
in our atmosphere brought about by increasing
greenhouse gases, and the climatic changes that

The  UV  Index
A Shining Success

              When you watch your local
              weather forecast, does the meteo-
              rologist report the UV Index? If
              so, your city is one of the com-
munities for which UV Index information is
available. The UV Index measures the ultraviolet
intensity at die earths surface when the sun is
highest in the sky. It indicates the degree of cau-
tion you should take when working, playing, or
exercising outdoors. Alan Geller, of the Boston
University Medical Center, agrees that "the UV
Index is an easy-to-use reminder to help all
Americans protect diemselves from the sun."
   To derive die index,
the National Wcadier
Service (NWS) looks at
ozone data from satellite
observations, atmos-
pheric pressure and tem-
perature forecasts,
elevation, and expected
cloudiness. NWS then
computes a regional
index with a range of 0
to 10+. Lower numbers
indicate a minimal or
low exposure level while
higher numbers indicate
a high exposure level.
According to Craig
Long of NWS, "the UV
Index has been verified
for the summer months since its inception in
1994. Due to its accuracy, the UV Index should
be considered a good forecasting tool."
   EPA works cooperatively widi NWS and the
Centers for Disease Control and Prevention
(CDC) on, public outreach and education cam-
paigns to encourage people to take note of the
U V Index every day. As part of its outreach
efforts, EPA is working with several major league
baseball teams to promote the UV Index. During
games, teams display the UV Index on  their giant
screens along with messages to help fans protect
diemselves from overexposure, to the sun. EPA's
Sun Wise School Program (see page 3) will also
use the UV  Index as a cornerstone of its efforts to
educate young children about sun protection.
   Studies show that the outreach efforts under-
taken by EPA, NWS, and CDC enhance aware-
ness of the effects of overexposure to the sun's
ultraviolet rays, and provide the public with
actions they can take to reduce the harmful
effects of overexposure, which include sunburn,
skin cancers, aging and wrinkling of the skin,
ocular damage, cataracts, and immune suppres-
sion. According to Thomas F. Downham II,
M.D., from the National Association of Physi-
cians for the Evironment (NAPE), "daily aware-
ness of the UV Index along with use of sunscreen
(SPF 15 or greater), wearing a hat and shirt, and
                       avoidance of sunburn
                       by seeking shade from

                       effects from overexpo-
                       sure to sunlight. The,,
                       daily UV Index is
                       available from many
                       local newspapers, TV
                       weather reports, and
                       Internet Web sites."

                       cations are available
                       that  provide more

SunWise  Plans  to  Teach  Sun  Safety
              With one in five Americans devel-
              oping skin cancer, childhood
              education about sun safety is a
              vital step toward reducing risk
and improving public health. In response to this
serious health issue, EPA and schools across the
country are teaming up in the SunWise School
Program. SunWise aims to teach children in ele-
mentary school and their caregivers how to pro-
tect themselves from overexposure to the sun.

Why teach children about sun protection?

   Overexposure to the sun's ultraviolet (UV)
rays damages human health.  Besides the immedi-
ate effect of sunburn, over time excess UV radia-
tion can cause skin cancer and other skin
disorders, eye damage, and immune system sup-
pression. Protecting children from UV overexpo-
sure is very important because 80 percent of
lifetime sun exposure occurs before the age of 18.
Just one or two blistering sunburns in childhood
might double the risk of developing melanoma.
Teaching children about sun safety is the key to
reducing the risk of future health problems.

How  can schools participate?
   Participating schools will sponsor activities
that raise children's awareness of the largely pre-
ventable health risks from UV radiation and
teach  simple steps to avoid overexposure. Such
activities might include:
;jl£   Reporting the UV Index daily.
-^-   Educating children about stratospheric
      ozone, ozone depletion, and UV radiation.
^.   Sponsoring 'Safe Fun in the Sun days.
y^.   Providing shade cover in outdoor areas.
^-   Inviting health pro-
      fessionals, environmen-
      talists, and meteorologists to
      speak with school children.
   Participating schools will receive a program
tool kit including activity guides, interactive
games, science experiments, videos, and a UV
Index database. Also, "train the trainer"  sessions
will be available to communities and
schools. Participants can share their ideas
for projects and check the progress
of others on die SunWise School home page.
Beginning in 1998, pilot schools in Boston, San
Francisco,  and Phoenix will test these program
materials and begin implementing sun protection
practices. The pilot will be expanded to addi-
tional cities in 1999 in preparation for a national
SunWise launch hi 2000.

Who can get involved?
  Teachers, parents, health professionals, envi-
ronmental groups, educational organizations, and
others can participate in SunWise by helping stu-
dents learn about sun protection. SunWise Com-
munity Planning Teams have been established in
each pilot community to aid in the design and
development of this program. With everyone's
help, sun safety can grow beyond school class-
rooms to help the entire community.

                                             Since the last update in September
                                    1997, the SNAP program has published several

                                    ceptable alternatives. EPA has added all of these
                                    SNAP lists of acceptable and unacceptable alter-
                                    natives to its ozone depletion Web site

                                    tutes, most notably n-propyl-bromide. As these
                                    new substitutes emerge, the suitability of main-
                                    taining current exemptions for HCFC-l4lb use
                                    in aerosols and pressurized dispensers is also
                                                being reviewed under a new pro-

   Another major SNAP effort is the creation of
an outreach report that reviews the many alter-
natives available for halons. The  report, now
being drafted, will discuss how to safely and
responsibly make the shift to new fire protec-
tion technologies in the following four volumes:

   • Corporate Structures in the Fire Protection
    Industry.
   • Safety Guide for Decommissioning Halon
    Systems: Generic instructions for safe
    decommissioning and manufacturers' speci-
    fications for handling specific equipment.
   • Fire Protection Options: Details the different

EPA Proposes Venting  Regulation
   Under Section 608 of the Clean Air Act (CAA),
it is illegal to knowingly vent substitutes for chloro-
fluorocarbon (CFC) and hydrochlorofluorocarbon
(HCFC) refrigerants during die maintenance, ser-
vice, repair, or disposal of air-conditioning and
refrigeration equipment. In June, EPA proposed a
regulation to fully implement this venting prohibi-
tion. In brief, die proposed regulations would
accomplish die following:
   •  Extend to hydrofluorocarbon (HFC) and
     perfluorocarbon (PFC) refrigerants the
     requirements currendy in place for CFC and
     HCFC refrigerants. These requirements
     include: "required practices;" certification
     programs for recovery and recycling equip-
     ment, reclaimers, and technicians; leak repair
     requirements; safe disposal requirements;
     and a prohibition on die sale of refrigerant
     to anyone but certified technicians.
   •  Exempt certain substitute refrigerants from die
     vendng prohibition, including water, carbon
     dioxide, nitrogen, hydrocarbons (in industrial
     process refrigeration only), ammonia (in
     absorption units and in commercial and
     industrial process refrigeration only), and chlo-
     rine (in industrial process refrigeration only).
   •  Make minor changes to required practices,
     recovery equipment standards, and refrig-
     erant purity standards for CFCs and
     HCFCs to accommodate the addition of
     the HFC and PFC refrigerants.
   • Lower die maximum allowable leak rates for
     comfort cooling chillers, commercial refriger-
     ation, and industrial process refrigeration.
     The new maximum allowable leak rates
     would apply to equipment containing CFCs,
     HCFCs, HFCs, and PFCs.
   The full text of the proposed rule,
including the rationale for each provi-
sion, was published in die Federal Reg-
ister on June 11, 1998, at 63 FR
32044. This  text also can be

                         Partnering  for  a   Smooth
                         MDI  Transition
                             In 1996, metered-dose inhalers (MDIs) were
                             designated an "essential use" under the
                             Montreal Protocol because of their impor-
                             tance in treating serious respiratory diseases
                         and because chlorofluorocarbon (CFQ-free
                         MDIs were not available. Recently, however,  the
                         first CFC-free MDI was introduced. All major
                         pharmaceudcal companies are now reformulat-
                         ing their MDIs to be CFC-free.
                           EPA and the Food and Drug
                         Administration (FDA) are work-
                         ing together to achieve a safe
                         and orderly transition
                         from the use of
                         MDIs  that use
                         CFCs to those
                         Most patients and
                         health care providers recognize the
                         importance of maintaining FDA's role in manag-
                         ing a smooth transition and of a partnership
                         between FDA and EPA to facilitate that transi-
                         tion. Currently, FDA is reviewing public com-
                         ments received in response to an Advance Notice
                         of Proposed Rulemaking (ANPRM) published in
                         March 1997. Based on the large number of
                         public comments received, FDA estimates that it
                         will publish a Notice of Proposed Rulemaking
                         early in 1999.
  FDA and EPA recognize that involving patients
and health care professionals is critical to achieve a
successful transition. Joint outreach efforts among
industry, patient and health care professionals, and
government agencies will help educate patients,
dispel rumors, and minimize anxieties about the
transition. To this end, FDA, EPA, and the
              National Institutes of Health,

  EPA and FDA recognize that the MDI transi-
tion will most probably proceed over a number
of years. Both agencies are committed to working
with pharmaceutical companies to ensure that
adequate supplies of CFC-MDIs are available
during the transition period. In addition, EPA
will continue to work with patients, health care
professionals, and makers of MDIs to develop
additional outreach materials and to encourage a
smooth transition for everyone involved.

Report on the  Supply  and  Demand of
CFG-12 Refrigerant  in  the  United  States
A         recent EPA report concludes that the
         total inventory of chlorofluorocarbon-
         12 (CFC-12) refrigerant in the
         United States at the beginning of this
year was higher than estimated in 1997. The
report, issued in June of this year, includes infor-
mation on the projected supply and demand of
CFC-12 in the United States between 1998 and
2002. EPA's report concludes that the total
inventory of CFC-12 in the United States at the
beginning of this year ranged between 40 mil-
lion and 75  million pounds.
  Other key findings of the report include the
following:
  • Chemical  manufacturers, chemical packagers
    and reclaimers, original equipment manufac-
    turers (automakers), automotive parts retail-
    ers and  distributors, do-it-yourselfers,
    stationary and commercial air-conditioning
    and refrigeration distributors, and wholesale
    clubs hold most supplies of CFC-12.
  • Based on information from industry
    sources, it is highly unlikely that spot
    shortages of CFC-12 will occur in
    1998. In fact, the supply of CFC-12      !
    is plentiful in 1998, and anyone in        '
    the country should be able to obtain
    it. Significant shortages also are
    unlikely in 1999.
  • Reclamation of CFC-12 did not           :
    increase dramatically over the past year.
    Most recovered CFC-12 in the com-       <
    mercial and stationary sector is usually      :
    held by  equipment owners that use the
    recovered CFC-12 to service other
    equipment, rather than send it to          J
    reclaimers. Supermarkets, for example,      1
    frequently retrofit equipment at indi-       '••
    vidual stores and keep the recovered
    CFC-12 for units that still rely on it.
   • Aggressive law enforcement and industry
    vigilance in reporting suspicious CFC sup-
    plies greatly hindered illegal imports of
    CFC-12. EPA estimates that the volume of
    illegal trade was less than 10 million pounds
    per year for 1996 and 1997.
   • The national demand for CFC-12 in 1998
    is estimated to be 27 million pounds, with
    motor vehicle air-conditioning repair
    accounting for 83 percent of the annual
    demand. Demand is expected to decline as
    market  penetration of CFC-12 alternatives
    increases and existing CFC-12-based equip-
    ment stocks are retired. The estimated
    demand for 1998 is significantly lower than
    shown in the 1997 report because EPA
    revised some of the assumptions used in the
    modeling system that generates the demand
    figures.
   To obtain a copy of the report, call  EPA's
Stratospheric Ozone Information Hotline at
800 296-1996.
  On December 31, 1995, IJ.S.'manufacturers stopped producing
  CFC-12, -an -ozone-depleting refrigerant also known as TC-12. Use
  of CFC-T2 from .existing supplies, however, is not prohibited.
  Since the 1996 production phaseout of this widely used chemi-
  cal, the national _supply of^CFC-12 'has "depended upon the
 -' quantity of CFC-12 contained in stockpiles at the beginning of
^"1996, and on the quantity of CFC-12 reclaimed from existing
'-- air-corjditiqning and refrigeration equipment. The demand for
•^ CFC-12 is determined by the  number of air-conditioning and
  ^refrigeration systems that require refrigerant to replace CFC-12
  "lost through leakage and required upon servicing.

   implementation

By 2001, industrialized
nations must reduce methyl
bromide production by 50
percent, and by 2005, it
must be totally phased out.
For developing countries, a
complete phaseout of
methyl bromide is scheduled
for 2015. These guidelines
are part of more stringent
controls added to  the Mon-
treal Protocol at the Ninth
Meeting of the Parties held
in Montreal, Quebec, on
September 17, 1997.
The complete global phase-
out will require industrialized
countries to reduce consump-
tion by 25 percent in 1999,
then 50 percent in 2001, 70
percent in 2003, and finally
100 percent in  2005. This
action plan is based on 1991
consumption levels, which
were frozen in  1995. For
non-industrialized  countries,
there will be 20 percent
reduction in 2005  and then
100 percent in 2015, based
on an average of 1995-1998
consumption levels, which
wll be frozen in 2002.

about 27,000 tons oF methyl Bromide are used
Hi agriculture, while about 76,000 tons are used
globally. Unfortunately, .methyl bromide is toxic

   Methyl bromide is also a significant ozone-
depledrtfj; substance. On a per molecule basis
the bromine from methyl bromide is 50 times
more damaging to otorie  than the chlorine
from CFCs. Regulations that were put in place
in 199,3 will pliase out the production and
import of methyl bromide after January  1,
2001.  In addition EPA froze U.S. production
in 1994 at 1991 levels. (Sec sidebar at left).

 has a different range of pests. While methyl
 bromide kills everything, alternatives target a

 alternatives must have a good understanding of
 not only the type and population of the pests,
 but also the most effective measures of control
 and the best times to use them.   ,     :

Global Warming
lyiay interfere
with Ozone.Layer

According to a recent study,
increasing levels of greenhouse
gases (GHGs)—those that can
cause global warming by trapping
the earth's heat in the atmos-
phere—may  thwart recovery of
the ozone layer.

The connection between GHGs
and ozone depletion lies in the
fact that GHGs, which can warm
the lower atmosphere, actually
cool the upper atmosphere, or
stratosphere. The chemistry that
leads to ozone depletion is highly
sensitive to temperature. Extremely
cold temperatures over the polar
regions create conditions that
facilitate rapid ozone depletion.

In a model simulation by scien-
tists at  NASA's Goddard Institute
for Space Studies, elevated levels
of carbon dioxide (C02)-the pri-
mary GHG of concern-caused
ozone depletion to continue well
after the abundance of chlorine
(released from CFCs) had declined.
Without such interference from
C02, ozone  loss would likely par-
allel more closely the rise and fall
of stratospheric chlorine levels. In
the NASA model, Arctic ozone loss
was most severe between the
years 2010 and 2019, roughly a
decade after stratospheric chlorine
levels had peaked.

might result, complicate the picture of how quickly
the ozone layer will recover.
   Atmospheric measurements also show an increase
in the abundance of CFC substitutes, another sign
that the Montreal Protocol is working. This obser-
vation would be expected given the policy direction
taken by most nations to replace CFCs with
hydrochlorofluorocarbons (HCFCs) (which have a
lower ozone depletion potential than CFCs) and
hydrofluorocarbons (HFCs) (which have no ozone
depletion potential). In the United States, EPA's
Stratospheric Protection Division has approved the
use of HCFCs and HFCs as CFC substitutes in
numerous applications.
   Severe ozone loss  over the Antarctic during
springtime in the southern hemisphere continues
unabated. Because of unusually cold winters in
the Arctic, stratospheric ozone levels have been
extremely low in recent years.
   All told, the 1998 assessment illustrates
the effectiveness of the global  transition away
from ozone-depleting substances thus far, yet it also
reminds us that our commitments to reduce ODS
emissions cannot produce changes overnight—we
will face a depleted ozone layer for decades to come.
The report further reinforces the need to stay the
course in ensuring continued compliance with the
Montreal Protocol if ozone layer recovery is ever to
be achieved.

                                    from
enforcement efforts. Since November 1997, this
office has named 30 parties in illegal CFC
actions, resulting in settlements totaling
$81,213. In one recent case, a facility allegedly
employed an uncertified technician who did not
use required CFC recovery and recycling equip-
ment to service air conditioners and water cool-
ers. EPA is seeking a $129,400 fine in this case.
   EPA cracked down in other parts of the coun-
try as well, often with even more serious conse-
quences. In March 1998, the U.S. Attorney for
the Northern District of Ohio sentenced Herman
Brodzenski to 12 months in  a federal prison for
illegally certifying 100 refrigerant technicians.
   EPA's success in enforcing Title VI regulations
is expected to increase in the future. According to
Dawn Banks, of EPA's Office of Compliance,
"Now that the Title VI rules have been out there
for a few years, and we have  made extensive,
repeated efforts to educate the public about the
regulations, there is really no excuse for noncom-
pliance. Today, we are less and less likely to be
lenient when pursuing penalties."

                                    EPA Prepares for the Year 2000
                                        It seems that every day, newspapers, maga-
                                        zines, and TV stations report new challenges
                                        presented by the Year2000 computer issue.
                                    To promote a better understanding of the poten-
                                    tial effects of "Y2K" computer problems on envi-
                                    ronmental protection  issues, EPA has launched a
                                    dialogue with its partners and customers.

                                       Until the end of 1999, EPA and other federal
                                    agencies will be working with industry, state and
                                    local governments, organizations, and private cit-
                                    izens to address Y2K challenges. Because many
                                    aspects of environmental protection rely on
                                    automated reporting and record keeping, EPA is
                                    taking a lead in fostering Y2K information
                                             exchange, so that no one is taken by surprise as
                                             the new millennium begins.

                                                EPA is interested in learning about its cus-
                                             tomers' concerns, experiences, or innovative
                                             approaches to dealing with Y2K. For more infor-

Going  to  the  Source
EPA Petition  Process Curbs  Illegal Imports
         etween January and June, EPA
         responded to 93 petitions from com-
         panies seeking to import previously
         used ozone-depleting substances
(ODS) into the United States from other coun-
tries. Although the Clean Air Act (CAA)
Amendments of 1990 ban the import of the
ODSs most destructive to the ozone layer, such
as chlorofluorocarbons (CFCs) and halons, cer-
tain exemptions exist for chemicals that have
been used and removed from operating equip-
ment. Allowing the import of these used sub-
stances helps optimize the use of existing
supplies, discourages the production of virgin
material, discourages venting of the substance to
the atmosphere, and prevents shortages in sec-
tors that still rely on these substances.        •""
      . set up the petition process so the Agency
could independently verify that substances'!a per-
son wishes to import have, in fact, been previ-
ously used. Companies that want to importpjSJ7
substances submit their request to EPA. The I x
  requests must detail the original source facility
  where the substance was used. EPA works closely
  with U.S. Customs, the Department of Justice,
  and other relevant agencies to minimize illegal
  imports of ODSs and to ensure those who do
  import illegally are caught and convicted.
    The number of petitions submitted to EPA
  has increased every year since the phaseout dates
  for ODSs were established under the CAA. In
  the last 6 months of 1995, EPA received 31 peti-
  tions; in 1996, EPA received 73 petitions, and in
  1997, the number of petitions submitted
  climbed to 182.
