.3 OVERVIEW

The docket for tebufenpyrad is now open, in itiating the public co mment period for the registration review (docket num ber EPA-HQ-OPP-2014-0218) associat ed with this Preliminary Work Plan (PWP). Tebufenpyrad is an insec ticide/miticide registered for use on ornamental plants grown in commercial greenhouses for th e control of mites, a phids, grape mealybug, pear psylla, serpentine leafminer, thrips, and whiteflies.

Prior to initiation of the regist ration review for tebufenpyrad, the sole registrant of tebufenpyrad products, Nichino America, Inc., informed th e Agency that it was intending to request voluntarily cancellation of all of its tebufe npyrad product registrati ons (EPA Reg. Nos. 71711- 22, technical formulation, and 71711-23, end us e formulation). On April 8, 2014, Nichino America, Inc., submitted a letter requesting volu ntary cancellation of all of their products containing the active ingredient tebufenpyrad an d waiving the 180-day public comment period in lieu of a 30-day public comment period under FIFR A Section 6(f). These two products are the last tebufenpyrad pesticid e product registrations in the United States. A copy of the request for voluntary cancellation and the Fe deral Register Notice announci ng its receipt by the Agency have been placed in the docket for this Registration Review.

The Agency had intended to open the tebufenpyr ad docket with a PWP that explained what EPA’s Office of Pesticide Programs knows about te bufenpyrad, highlighting anticipated data and assessment needs, identifying the types of inform ation that would be especially useful to the Agency in conducting the review, and providing an anticipated timeline for completing the registration review for tebufenpyra d. However, due to the request from Nichino America, Inc. to voluntarily cancel all of its tebuf enpyrad product registra tions in the United States, the Agency anticipates closing this registra tion review case once all tebufenpyrad product registrations have been cancelled. Should these voluntary cancella tions not occur, the Agency will amend this PWP and include, among other things, anticipated data and assessment needs and an anticipated timeline for the registration review.

STATUTORY AND REGULATORY AUTHORITY

The Food Quality Protection Act (FQPA) of 1996 mandated a registration review program. All pesticides distributed or sold in the United Stat es (U.S.) generally must be registered by the Environmental Protection Agency (EPA or the Ag ency), based on scientific data showing that they will not cause unreasonable ri sks to human health or the environment when used as directed on product labeling. The registration review program is intended to ma ke sure that, as the ability to assess risk evolves and as policies and practices change, all registered pesticides continue to meet the statutory standard of no unreasonabl e adverse effects to human health or the environment. Changes in science, public policy, and pesticide use practices will occur over time. Through the registration review prog ram, the Agency periodically r eevaluates pesticides to make sure that as change occurs, products in the mark etplace can be used safely. Information on this program is provided on EPA’s website. 1

1 http://www.epa.gov/oppsrrd1/registration_review/4 The Agency is implementing the registration revi ew program pursuant to Section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), a nd will review each registered pesticide every 15 years to determine whether it continues to meet th e FIFRA standard for registration. The regulations governing regi stration review begin at 40 CFR 155.40. The Agency will consider benefits information and data as required by FIFRA. The public phase of registration review begins when the initial docket is opened for each case. The docket is the Agency’s opportunity to state what it knows about the pesticide and what additional risk analyses

and data or information it believes are need ed to make a registration review decision.

PC code 090102

Case Number 7435

CAS Number 119168-77-3 Year first registered 2002 Pesticide Type Insecticide/Miticide Chemical class Pyrazole Reregistration Eligibility Decision (RED) Tebufenpyrad was registered afte r November 1984; therefore, it was not subject to reregistration. Cumulative group EPA has not made a common mechanism of toxicity finding as to tebufenpyrad and any other substances and tebufenpyrad does not appear to produce a toxic metabolite produced by other

substances. 40 CFR Citation There are no registered tebufenpyrad food/feed uses and no

established toleran ces for tebufenpyrad. Dual-use Conventional pesticidal uses only Non-pesticidal uses No non-pesticidal uses of tebufenpyrad

NEXT STEPS

On August 6, 2014, EPA published a Federal Regist er Notice announcing rece ipt of the request to voluntarily cancel Nichino America, Inc. pestic ide registrations with a 30-day public comment period [79 FR 45803]. EPA intends to grant this request at the close of the comment period unless the Agency receives substantive comments within the comment period that would merit its further review of the request, or unless the registrant withdraws their request within this period. The Agency anticipates closing the re gistration review case for tebufenpyrad once all5 tebufenpyrad product registrations have been cancelled. Pursuant to 40 CFR § 155.42(c), the Agency “will close a registra tion review case if all products in the case are cancelled.”

If the affected products are not cancelled, the Ag ency will amend this PWP to reflect potential

data needs for and the schedul e for the registration review.
