INTRODUCTION 

This is the Environmental Protection Agency's (EPA or the Agency) Registration 

Review Case Closure for flufenpyr-ethyl (registration review docket EPA-HQ-OPP2014-0768). Flufenpyr-ethyl is an herbicide that was previously registered for use on 

field com, soybeans, and sugarcane, but for which all registrations have been canceled as 

discussed below. 

The Agency is implementing the registration review program pursuant to Section 

3(g) ofthe Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and will review 

each registered pesticide every 15 years to determine whether it continues to meet the 

FIFRA standard for registration. Changes in science, public policy, and pesticide use . 

practices occur over time. The registration review program is intended to make sure that, 

as the ability to assess risk evolves and as policies and practices change, all registered 

pesticides continue to meet the statutory standard. The public phase of registration review 

begins when the initial docket is opened for each case. Information on this program is 

provided on the Agency's website1• 

Pursuant to 40 CFR 155.50, the Agency formally initiated registration review for 

flufenpyr-ethyl (case 7262). The following timeline highlights significant events that· 

have occurred during the registration review of flufenpyr-ethyl: 

• December 19, 2014- Published the Flufenpyr-ethyl Preliminary Work Plan and 

supporting documents in the registration review docket (EPA-HQ-OPP-2014-

0768) for a 60-day public comment period. 

• March 19, 2015 - Valent USA Corporation (Valent), the sole technical and eq.duse product registrant for flufenpyr-ethyl, requested to voluntarily cancel all of its 

flufenpyr-ethyl product registrations. These were the last two flufenpyr-ethyl 

products registered for use in the United States. 

• May 14, 2015 - The Flufenpyr-ethyl Final Work Plan (FWP) was signed. The 

FWP noted Valent's request to voluntarily cancel all of its flufenpyr-ethyl product 

registrations and the Agency's intention to announce receipt of this request in a 

forthcoming Federal Register notice. 

• July 8, 2015 - Published a Notice of Receipt of Requests to Voluntarily Cancel 

Certain Pesticide Registrations and Amend Registrations To Terminate Certain 

Uses, including cancellations offlufenpyr-ethyl registrations, in the Federal 

Register (80 FR 39100; FRL-9928-54). No comments were received during the 

30-day comment period. 

• September 22, 2015 - Published a Product Cancellation Order and/or 

Amendments to Terminate Uses for Certain Pesticide Registrations, including

cancellations of flufenpyr-ethyl registrations, in the Federal Register (80 FR 

57179; FRL-9933-58). 

BACKGROUND INFORMATION 

In March 2015, Valent, the sole technical and end-use product registrant for 

flufenpyr-ethyl, informed the Agency that it was requesting to voluntarily cancel all 

flufenpyr-ethyl product registrations. Following publication of a Federal Register notice 

announcing receipt of this request and the end of the public comment period, the Agency 

issued the product cancellation order on September 22, 2015 for all flufenpyr-ethyl 

product registrations. The effective cancellation date is September 22, 2015. (Copies of 

those notices are included in the docket for this registration review.) Valent noted that 

there are no existing stocks of these product registrations (EPA Registration Numbers 

59639-109 and 59639-11 0) and did not request any existing stocks provisions. 

Therefore, no existing stocks provision is provided for these product registrations. 

REGISTRATION REVIEW CASE CLOSURE 

As stated in the Flufenpyr-ethyl FWP, the Agency had intended to call in data and 

revise the existing risk assessments for flufenpyr-ethyl. However, following publication 

of the FWP, all U.S. flufenpyr-ethyl product registrations were voluntarily cancelled 

effective September 22, 2015. In addition, there are no existing stocks offlufenpyr-ethyl. 

Therefore, due to the cancellation of all flufenpyr-ethyl product registrations in the 

United States, updated risk assessments and additional data are no longer required and the 

Agency is closing the registration review case. 

Pursuant to 40 CPR§ 155.42(c), which provides that the Agency "will close a 

registration review case if all products in the case are canceled," the Agency is closing 

the registration review case for flufenpyr-ethyl, thus concluding the flufenpyr-ethyl 

registration review.
