ENVIRONMENTAL PROTECTION AGENCY

Federal Register Volume 81, Issue 46 (March 9, 2016)

This notice announces the availability of EPA's proposed interim mitigation decision for paraquat dichloride (paraquat) and opens a public comment period on this proposed interim mitigation decision. 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, that the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. 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. EPA may pursue mitigation at any time during the registration review process if it finds that a pesticide poses unreasonable adverse effects to human health or the environment. Based on the number and severity of paraquat human health incidents, the EPA believes that the mitigation measures outlined in this proposed interim mitigation decision are necessary to address identified human health risk concerns.

Paraquat Dichloride; Proposed Interim Mitigation Decision; Notice 
of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces the availability of EPA's proposed 
interim mitigation decision for paraquat dichloride (paraquat) and 
opens a public comment period on this proposed interim mitigation 
decision. 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, that the pesticide can 
perform its intended function without unreasonable adverse effects on 
human health or the environment. 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. EPA may pursue mitigation at any time during the 
registration review process if it finds that a pesticide poses 
unreasonable adverse effects to human health or the environment. Based 
on the number and severity of paraquat human health incidents, the EPA 
believes that the mitigation measures outlined in this proposed interim 
mitigation decision are necessary to address identified human health 
risk concerns.

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 the Chemical Review Manager 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.

II. What action is the agency taking?

    Pursuant to 40 CFR 155.58, this notice announces the availability 
of EPA's proposed interim mitigation decision for paraquat, and opens a 
60-day public comment period on the proposed interim mitigation 
decision. Paraquat is a widely used broad spectrum herbicide for the 
control of weeds in many agricultural and non-agricultural settings, 
and is also used as a defoliant on crops, prior to harvest. It is 
classified as restricted use due to high toxicity. An estimated 1.5 tsp 
can be lethal if ingested and there is no known antidote. Paraquat 
dichloride is associated with a disproportionately high number of 
incidents including accidental ingestions typically leading to 
fatalities as well as occupational spills, splashes, and leaks 
resulting in

[[Page 12490]]

severe and often damaging dermal or ocular contact. Paraquat is known 
to be corrosive to skin and eyes. EPA recently reviewed all available 
incident information and determined that mitigation measures to address 
these human health risk concerns are necessary. EPA has had some 
discussions with the paraquat technical registrants that suggest that 
the mitigation measures could be adopted voluntarily by pesticide 
manufacturers.
    The registration review docket for a pesticide includes earlier 
documents related to the registration review of the case along with 
supporting materials for this proposed interim mitigation decision. 
Following public comment, the Agency will issue a final interim 
mitigation decision for products containing paraquat. Notwithstanding 
this action, paraquat is still undergoing registration review. Within 
the next several years, EPA anticipates conducting comprehensive draft 
human health and ecological risk assessments for paraquat, followed by 
a proposed registration review decision, all of which will be posted 
for public comment.
    The registration review program is being conducted under 
congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public. Section 3(g) of the 
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 
136a(g)) required EPA to establish by regulation procedures for 
reviewing pesticide registrations, originally with a goal of reviewing 
each pesticide's registration every 15 years to ensure that a pesticide 
continues to meet the FIFRA standard for registration. The Agency's 
final rule to implement this program was issued in August 2006 and 
became effective in October 2006, and appears at 40 CFR part 155, 
subpart C. The Pesticide Registration Improvement Act of 2003 (PRIA) 
was amended and extended in September 2007. FIFRA, as amended by PRIA 
in 2007, requires EPA to complete registration review decisions by 
October 1, 2022, for all pesticides registered as of October 1, 2007.
    The registration review final rule at 40 CFR 155.58(a) provides for 
a minimum 60-day public comment period on all proposed registration 
review decisions. This comment period is intended to provide an 
opportunity for public input and a mechanism for initiating any 
necessary amendments to the proposed interim mitigation decision. All 
comments should be submitted using the methods in ADDRESSES, and must 
be received by EPA on or before the closing date. These comments will 
become part of the docket for paraquat. Comments received after the 
close of the comment period will be marked ``late.'' EPA is not 
required to consider these late comments.
    The Agency will carefully consider all comments received by the 
closing date and will provide a ``Response to Comments Memorandum'' in 
the docket. The final interim mitigation decision will explain the 
effect that any comments had on the final decision and provide the 
Agency's response to significant comments.

related to the registration review of paraquat are provided at: http://www.epa.gov/ingredients-used-pesticide-products/paraquat.

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