Tetrachlorvinphos Registration Review; Draft Human Health and
Ecological Risk Assessment; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's draft human
health and ecological risk assessment for the registration review of
tetrachlorvinphos and opens a public comment period on this document.
Registration review is EPA's periodic review of pesticide registrations
to ensure that each pesticide continues to satisfy the statutory
standard for registration, that is, the pesticide can perform its
intended function without unreasonable adverse effects on human health
or the environment. As part of the registration review process, the
Agency has completed a comprehensive draft human health and ecological
risk assessment for all tetrachlorvinphos uses. After reviewing
comments received during the public comment period, EPA will issue a
revised risk assessment, explain any changes to the draft risk
assessment, and respond to comments and may request public input on
risk mitigation before completing a proposed registration review
decision for tetrachlorvinphos. Through this program, EPA is ensuring
that each pesticide's registration is based on current scientific and
other knowledge, including its effects on human health and the
environment.

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, human
health, farm worker, and agricultural advocates; the chemical industry;
pesticide users; 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 affected by this action. If you have any questions

regarding the applicability of this action to a particular entity,
consult James Parker listed under FOR FURTHER INFORMATION CONTACT.

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 email. 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 preparing and submitting
your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.
    3. Environmental justice. EPA seeks to achieve environmental
justice, the fair treatment and meaningful involvement of any group,
including minority and/or low income populations, in the development,
implementation, and enforcement of environmental laws, regulations, and
policies. To help address potential environmental justice issues, the
Agency seeks information on any groups or segments of the population
who, as a result of their location, cultural practices, or other
factors, may have atypical or disproportionately high and adverse human
health impacts or environmental effects from exposure to the pesticide
discussed in this document, compared to the general population.

II. Authority

    EPA is conducting its registration review of tetrachlorvinphos
pursuant to section 3(g) of the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) and the Procedural Regulations for Registration
Review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides,
among other things, that the registrations of pesticides are to be
reviewed every 15 years. Under FIFRA, a pesticide product may be
registered or remain registered only if it meets the statutory standard
for registration given in FIFRA section 3(c)(5) (7 U.S.C. 136a(c)(5)).
When used in accordance with widespread and commonly recognized
practice, the pesticide product must perform its intended function
without unreasonable adverse effects on the environment; that is,
without any unreasonable risk to man or the environment, or a human
dietary risk from residues that result from the use of a pesticide in
or on food.

III. Registration Reviews

    As directed by FIFRA section 3(g), EPA is reviewing the pesticide
registration for tetrachlorvinphos to ensure that it continues to
satisfy the FIFRA standard for registration--that is, that
tetrachlorvinphos can still be used without unreasonable adverse
effects on human health or the environment. Tetrachlorvinphos is an
organophosphate (OP) insecticide used to control nuisance pests (e.g.
fleas and ticks) on domestic cats and dogs, in addition to livestock,
their premises, kennels, poultry houses, barns, and outdoor perimeter
treatments. EPA has completed a comprehensive draft human health and
ecological risk assessment, including an endangered species assessment,
for all tetrachlorvinphos uses.
    Pursuant to 40 CFR 155.53(c), EPA is providing an opportunity,
through this notice of availability, for interested parties to provide
comments and input concerning the Agency's draft human health and
ecological risk assessment for tetrachlorvinphos. Such comments and
input could address, among other things, the Agency's risk assessment
methodologies and assumptions, as applied to this draft risk
assessment. The Agency will consider all comments received during the
public comment period and make changes, as appropriate, to the draft
human health and ecological risk assessment. EPA will then issue a
revised risk assessment, explain any changes to the draft risk
assessment, and respond to comments. In the Federal Register notice
announcing the availability of the revised risk assessment, if the
revised risk assessment indicates risks of concern, the Agency may
provide a comment period for the public to submit suggestions for
mitigating the risk identified in the revised risk assessment before
developing a proposed registration review decision on
tetrachlorvinphos.
    The Agency issued a Final Work Plan (FWP) for tetrachlorvinphos in
December 2008, and data were called in. The reviews of those data are
incorporated into the draft risk assessments. The draft ecological risk
assessment identifies potential risks of concern for mammals, birds/
reptiles/terrestrial-phase amphibians, and freshwater invertebrates.
The draft human health risk assessment identifies potential non-cancer
risks for residential and occupational handlers and for certain post-
application exposure scenarios. In addition, there is a potential
cancer risk for residential post-application exposure scenarios and for
occupational handlers. Tetrachlorvinphos was also previously evaluated
for its potential to affect endocrine systems in mammals and wildlife
and the results of the agency's review are found in the Weight of
Evidence review in this registration review docket.
    1. Other related information. Additional information on
tetrachlorvinphos is available on the Pesticide Registration Review
Status Web page for this pesticide, http://iaspub.epa.gov/apex/pesticides/f?p=CHEMICALSEARCH:1. Information on the Agency's
registration review program and its implementing regulation is
available at http://www.epa.gov/oppsrrd1/registration_review.
    2. Information submission requirements. Anyone may submit data or
information in response to this document. To be considered during a
pesticide's registration review, the submitted data or information must
meet the following requirements:
     To ensure that EPA will consider data or information
submitted, interested persons must submit the data or information
during the comment period. The Agency may, at its discretion, consider
data or information submitted at a later date.
     The data or information submitted must be presented in a
legible and useable form. For example, an English translation must
accompany any material that is not in English and a written transcript
must accompany any information submitted as an audiographic or
videographic record. Written material may be submitted in paper or
electronic form.
     Submitters must clearly identify the source of any
submitted data or information.
     Submitters may request the Agency to reconsider data or
information that the Agency rejected in a previous review. However,
submitters must explain why they believe the Agency should reconsider
the data or information in the pesticide's registration review.
    As provided in 40 CFR 155.58, the registration review docket for
each pesticide case will remain publicly accessible through the
duration of the registration review process; that is, until all actions
required in the final decision

on the registration review case have been completed.

    Authority:  7 U.S.C. 136 et seq.

    Dated: January 8, 2016.
