Petition Requesting Cancellation of all Tetrachlorvinphos Pet
Uses and Extension of Comment Period for Petition Requesting
Cancellation of Propoxur Pet Collar Uses; Notice of Availability
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: On April 24, 2009, the Agency received a petition from the
Natural Resources Defense Council (NRDC) to cancel all pet uses for the
pesticide tetrachlorvinphos (TCVP) and a supplement to a previous NRDC
petition to cancel all pet collar uses for the pesticide propoxur. NRDC
requested these cancellations based on their belief that EPA failed to
adequately assess residential exposures to TCVP and propoxur pet
collars. NRDC believes that EPA used incorrect exposure assumptions
leading to underestimation of residential risk in the TCVP
Reregistration Eligibility Decision (RED), Propoxur RED, and N-methyl
Carbamate (NMC) Cumulative Risk Assessment (CRA). On April 8, 2009, the
Agency opened a 60-day public comment period for the petition to cancel
propoxur pet collar uses, originally scheduled to close June 8, 2009.
This notice extends the comment period on the propoxur petition to
correspond with the timing of the TCVP comment period.
DATES: Comments must be received on or before August 4, 2009.
ADDRESSES: Submit your comments for TCVP, identified by docket
identification (ID) number EPA-HQ-OPP-2009-0308, and for propoxur,
identified by docket ID number EPA-HQ-OPP-2009-0207, by one of the
following methods:

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does This Action Apply to Me?
This action is directed to the public in general, and may be of
interest to a wide range of stakeholders including environmental and
human health advocates; the chemical industry; pesticide users; pet
owners; and members of the public interested in the sale, distribution,
or use of pesticides. Since others also may be interested, the Agency
has not attempted to describe all the specific entities that may be

B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as
CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
2. Tips for preparing your comments. When submitting comments,
remember to:
i. Identify the document by docket ID number and other identifying
information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
vi. Provide specific examples to illustrate your concerns and
suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
viii. Make sure to submit your comments by the comment period
deadline identified.
II. Background
The Agency has opened a 60-day comment period for an NRDC petition
requesting the cancellation of all tetrachlorvinphos pet uses. The
petition was filed on April 24, 2009, and NRDC claims that the Agency
did not include the TCVP pet collar use pattern, which is the worst
case exposure scenario, and that the Agency used assumptions which
underestimated exposures when conducting the risk assessment in support
of the 2002 Tetrachlorvinphos RED.
On April 24, 2009, NRDC also submitted a supplement to their
previous petition to cancel all pet collar uses for propoxur, which
provided some additional information on the pesticide. The original
NRDC petition, submitted November 2007, was recently posted for a 60-
day public comment period under docket ID number EPA-HQ-OPP-2009-0207
through a notice of availability published in the Federal Register
issue of April 8, 2009 (74 FR 15980)(FRL-8408-4). The public comment
period for that docket was previously scheduled to close on June 8,
2009. However, this Federal Register notice will extend the public
comment period for that docket to 60-days from the publication of this
notice. Note that for propoxur, pet collars are currently the only
products registered for use on pets. There are no other types of pet
products, such as spot-ons, sprays, or shampoos, registered for use on
pets. Therefore, NRDC's petition to cancel applies only to propoxur pet
collar uses.
In both the TCVP and propoxur petitions, NRDC claims that
residential exposures may be significantly higher than estimated by EPA
through common daily activities between children and pets. NRDC also
cites specific revised hand-to-mouth exposure scenarios from published
studies which they feel should have been included in the TCVP and
propoxur exposure assessments.
NRDC conducted a study designed to estimate exposure to TCVP and
propoxur from flea collars. A summary of the study was submitted in an
issue paper along with the petition to cancel pet uses of TCVP and
propoxur. The Agency has requested that NRDC provide additional
information regarding the study. The Agency's letter requesting
information and NRDC's response will be included in both the TCVP and
the propoxur dockets.
