         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)

PART 82_PROTECTION OF STRATOSPHERIC OZONE--Table of Contents

              Subpart A_Production and Consumption Controls

   Sec. Appendix G to Subpart A of Part 82--UNEP Recommendations for
Conditions Applied to Exemption for Essential Laboratory and Analytical
                                  Uses

    1. Essential laboratory and analytical uses are identified at this
time to include equipment calibration; use as extraction solvents,
diluents, or carriers for chemical analysis; biochemical research; inert
solvents for chemical reactions, as a carrier or laboratory chemical and
other critical analytical and laboratory purposes. Pursuant to Decision
XI/15 of the Parties to the Montreal Protocol, effective January 1, 2002
the following uses of class I controlled substances are not considered
essential under the global laboratory exemption:
    a. Testing of oil and grease and total petroleum hydrocarbons in
water;
    b. Testing of tar in road-paving materials; and
    c. Forensic finger printing.
    Production for essential laboratory and analytical purposes is
authorized provided that these laboratory and analytical chemicals shall
contain only controlled substances manufactured to the following
purities:

CTC (reagent grade)--99.5
1,1,1,-trichloroethane--99.5
CFC-11--99.5
CFC-13--99.5
CFC-12--99.5
CFC-113--99.5
CFC-114--99.5
Other w/ Boiling P20 degrees C--99.5
Other w/ Boiling P<20 degrees C--99.0
    d. Testing of organic matter in coal.
    2. These pure, controlled substances can be subsequently mixed by
manufacturers, agents or distributors with other chemicals controlled or
not controlled by the Montreal Protocol as is customary for laboratory
and analytical uses.
    3. These high purity substances and mixtures containing controlled
substances shall be supplied only in re-closable containers or high
pressure cylinders smaller than three litres or in 10 millilitre or
smaller glass ampoules, marked clearly as substances that deplete the
ozone layer, restricted to laboratory use and analytical purposes and
specifying that used or surplus substances should be collected and
recycled, if practical. The material should be destroyed if recycling is
not practical.
    4. Parties shall annually report for each controlled substance
produced: the purity; the quantity; the application, specific test
standard, or procedure requiring its uses; and the status of efforts to
eliminate its use in each application. Parties shall also submit copies
of published instructions, standards, specifications, and regulations
requiring the use of the controlled substance.
    5. Pursuant to Decision XVIII/15 of the Parties to the Montreal
Protocol, methyl bromide is exempted for the following approved
essential laboratory and analytical purposes listed in following items
(a) through (d). Use of methyl bromide for field trials is not an
approved use under the global laboratory and analytical use exemption.
The provisions of Appendix G, paragraphs (1), (2), (3), and (4),
regarding purity, mixing, container, and reporting requirements for
other exempt ODSs, also apply to the use of methyl bromide under this
exemption.
    a. Methyl bromide is exempted as an approved essential laboratory
and analytical use as a reference or standard to calibrate equipment
which uses methyl bromide, to monitor methyl bromide emission levels, or
to determine methyl bromide residue levels in goods, plants and
commodities;
    b. Methyl bromide is exempted as an approved essential laboratory
and analytical when used in laboratory toxicological studies;
    c. Methyl bromide is exempted as an approved essential laboratory
and analytical use to compare the efficacy of methyl bromide and its
alternatives inside a laboratory; and
    d. Methyl bromide is exempted as an approved essential laboratory
and analytical use as a laboratory agent which is destroyed in a
chemical reaction in the manner of feedstock.
