Appendix G to Subpart A of Part 82 - UNEP Recommendations for Conditions Applied to Exemption for Essential Laboratory and Analytical Uses
40:21.0.1.1.1.1.1.24.7 : Appendix G
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 P>20 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.
