EPA List of Inerts. This
substance was formerly on List 2.
Note:
US EPA allows so-called "Inert" ingredients to be commonly
mixed with the "active" pesticidal ingredient to
create a formulated pesticide product. According
to EPA, "The term `inert' is not intended to imply
nontoxicity; the ingredient may or may not be chemically active."
"Inert" ingredients include solvents, emulsifiers,
spreaders, and other substances mixed into pesticide products
to increase the effectiveness of the active ingredients, make
the product easier to apply, or to allow several active ingredients
to mix in one solution. Both US EPA and California Department
of Pesticide Regulation require pesticide manufacturers to
identify inert ingredients in their products but do not disclose
this information to the general public because the pesticide
industry considers product formulations trade secrets, protected
by law and by the US EPA. The US EPA category of Inerts (as
of September 2003):
List 1 - Of Toxicological
Concern
List 2
- Potentially Toxic / High Priority for Testing
List
3 - Of Unknown Toxicity
List 4A - Generally Regarded as Safe
List 4B - EPA states it has Sufficient Information to Reasonably
Conclude that the Current Use Pattern in Pesticide Products
will not Adversely Affect Public Health or the Environment

Inert
ingredients; Revocation of Pesticide Tolerance Exemptions
for Three CFC Chemicals. FINAL RULE.
EPA is revoking exemptions from the requirement of
a tolerance for three inert ingredients (dichlorodifluoromethane,
dichlorotetrafluoroethane, and trichlorofluoromethane)
because these substances no longer have active Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA) pesticide product registrations
and/or because their use in pesticide
products sold in the United States (U.S.) has been prohibited
under the Clean Air Act (CAA) for over a decade due to EPA's
ban on the sale or distribution, or offer for sale or distribution
in interstate commerce of certain nonessential products that
contain or are manufactured with ozone depleting compounds...
Nonetheless,
EPA will establish and maintain tolerances and tolerance exemptions
even when corresponding domestic uses are canceled if the
tolerances, which EPA refers to as ``import tolerances,''
are necessary to allow
importation into the United States of food containing such
pesticide residues.
However, where there are no imported commodities that require
these import tolerances, the Agency believes it is appropriate
to revoke tolerances and tolerance exemptions for unregistered
pesticide chemicals in order to prevent potential misuse.
40 CFR
chapter I is amended as follows:
PART 180--[AMENDED]
•
1. The authority citation for part 180 continues to read as
follows:
Authority: 21 U.S.C. 321(q), 346a and 371.
• 2. Section 180.910
is amended by removing the following exemptions and
any associated Limits and Uses from the table: Dichlorodifluoromethane,
Dichlorotetrafluoroethane, and
Trichlorofluoromethane.
• 3. Section 180.930 is
amended by removing the following exemptions and
any associated Limits and Uses from the table: Dichlorodifluoromethane
and Trichlorofluoromethane. |

Inert
Ingredients; Proposal to Revoke Pesticide Tolerance.
EPA is proposing to revoke exemptions from the requirement
of a tolerance for three inert ingredients (dichlorodifluoromethane,
dichlorotetrafluoroethane, and trichlorofluoromethane)
because these
substances are no longer in active Federal Insecticide, Fungicide,
and Rodenticide Act (FIFRA) pesticide product registrations
and/or their use in pesticide products sold in the U.S. has
been prohibited under the Clean Air Act for over a decade
by EPA's ban on the sale or distribution, or offer for sale
or distribution in interstate commerce
of certain nonessential products that contain or are manufactured
with ozone depleting compounds. These ingredients are
subject to reassessment by August, 2006 under section 408(q)
of the Federal Food,
Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality
Protection Act of 1996 (FQPA).
Therefore,
it is proposed that 40 CFR part 180 be amended as follows:
PART 180--AMENDED
1. The authority citation for part 180 continues to read as
follows:
Authority: 21 U.S.C. 321(q), 346a and 371.
Sec. 180.910 [Amended]
2. Section 180.910 is amended
by removing the following exemptions
and any associated Limits and Uses from the table:
Dichlorodifluoromethane, Dichlorotetrafluoroethane,
and
Trichlorofluoromethane.
Sec. 180.930 [Amended]
3. Section 180.930 is amended
by removing the following exemptions
and any associated Limits and Uses from the table:
Dichlorodifluoromethane and Trichlorofluoromethane. |

Inert
Ingredients No Longer Used in Pesticide Products - Former
List 3 Inert.
EPA
is removing certain chemicals from its list of pesticide product
inert ingredients that are not currently used in pesticide
products. Future use of these chemicals as inert ingredients
in pesticide products will not be permitted unless a petitioner
or registrant satisfies all data requirements as identified
by the Agency, and the Agency is able to make a determination
that the use of the inert ingredient will not pose unreasonable
risk to human health or the environment. All tolerances or
exemptions from the requirement of a tolerance for the use
of these chemicals as inert ingredients in food- use pesticide
formulations will be proposed for revocation at a later date
in a separate Federal Register Notice. |
