EPA List of Inerts. This
substance was a former List
3.
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

Proposed
Significant New Use Rule (SNUR). PFOSH
is highly persistent in the environment and has a strong tendency
to bioaccumulate. Studies have found PFOS chemicals in very
small quantities in the blood of the general human population
as well as in wildlife, indicating that exposure to the chemicals
is widespread, and recent tests have raised concerns about their
potential developmental, reproductive, and systemic toxicity
(Refs. 1, 2, and 3). These facts, taken together, raise concerns
for long term potential adverse effects in people and wildlife
over time if PFOS should continue to be produced, released,
and built up in the environment. The chemical substances
subject to this supplemental proposed SNUR are listed in Table
2, Unit I.A. These chemical substances include PFOSH, PFOSS,
POSF, certain higher and lower homologues of PFOSH and POSF,
and certain other chemical substances, including polymers, that
are derived from PFOSH and its homologues. All of these chemical
substances are referred to collectively in this proposed rule
as perfluoroalkyl sulfonates, or PFAS. In the original proposed
SNUR (65 FR [[Page 11020]] 62319, October 18, 2000), these chemicals
had been referred to collectively as perfluorooctylsulfonates,
or PFOS, but commenters noted that this generic usage of PFOS
was inconsistent with 3M's use of PFOS to refer only to chemicals
with an eight-carbon, or C8, chain length. Many of the chemicals
in the proposed SNUR included a range of carbon chain lengths,
although they all did include C8 within the range. Accordingly,
EPA will use the generic term PFAS to refer to any chain length,
including higher and lower homologues as well as C8, and the
term PFOS to represent only those chemicals which are predominantly
C8. All of the chemical substances listed in this supplemental
proposed SNUR have the potential to degrade to PFOSH in the
environment. Information also suggests that these chemical substances
may be converted to PFOSH via incomplete oxidation during the
incineration of PFAS-containing materials. Once PFOSH has been
released to the environment, it does not undergo further chemical
(hydrolysis), microbial, or photolytic degradation. |

Proposed Rule. Notice
of Public Meeting. The EPA will conduct a public meeting
on the proposed significant new use rule (SNUR) on PFOS published
in the Federal Register issue of October 18, 2000. At this meeting,
persons who filed written comments on the proposed SNUR will
have the opportunity to clarify and expand on their comments,
and all interested persons will be able to identify issues of
concern. DATES: The public meeting will be held from 9 a.m.
to 4 p.m. on March 27, 2001. Interested parties are requested
to contact the technical person on or before Friday, March 16,
2001, to schedule presentations at the meeting. |
