abeling. 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 of no unreason~ble 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 program, the Agency periodically reevaluates pesticides to make 

sure that as change occurs, products in the marketplace can be safely used. Information on this 

program is provided on EPA's website. 1 

In 2006, the Agency implemented the Registration Review program pursuant to FIFRA 

Section 3(g), and will review each registered pesticides every 15 years to determine whether it 

continues to meet the FIFRA standard for registration. 

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

tepraloxydim (case 7257) in March 2014. The following timeline highlights significant events 

that have occurred during the registration review of tepraloxydim: 

• January 15, 2014- Nippon Soda Co., Ltd. c/o Nisso America Inc. (Nisso) submitted a 

letter to EPA requesting voluntary cancellation of all of their products containing the 

active ingredient tepraloxydim. 

• March 28, 2014- Publication of the Tepraloxydim Preliminary Work Plan, and the 

Request for Voluntary Cancellation ofTepraloxydim Registrations and Waiver of the 

180-Day Comment Period in the docket (EPA-HQ-OPP-2014-0246). The Agency 

received one comment from Nippon Soda Co., Ltd c/o to confirm their intent to 

voluntary cancel their tepraloxydim pesticide registrations and a request to maintain 

the existing tolerances through 2018 in order to avoid barriers to cross-border trade of 

tepraloxydim-treated commodities. 

• May 20, 2014 - Publication of a Notice of Receipt of Request to Voluntarily Cancel 

Certain Pesticide Registrations for tepraloxydim in the Federal Register (79 FR 

28920, FRL 9909-40). The Agency received one comment during the 30-day 

comment period from Nippon Soda Co., Ltd that discussed the importance of 

maintaining the existing tepraloxydim tolerances for importation purposes through 

2018. 

• August 6, 2014- Publication of a final Cancellation Order for all tepraloxydim 

product registrations in the Federal Register (79 FR 45798, FRL-9914-09).

Early in the Registration Review process for tepraloxydim in 2014, the sole technical and 

end-use product registrant, Nippon Soda Co., Ltd,. informed the Agency that it was requesting to 

voluntarily cancel all of its tepraloxydim product registrations (EPA Reg. Nos. 8033-12 and 

8033-13). Following publication of a May 20, 2014 Federal Register notice announcing receipt 

of this request and a 30-day public comment period, the Agency issued a Final Cancellation 

Order on August 6, 2014 cancelling all tepraloxydim product registrations (copies of those 

notices are included in the docket for this registration review). EPA Reg. Nos. 8033-12 and 

8033-13 were the last tepraloxydim pesticide producfregistrations in the United States. 

According to Nippon, tepraloxydim pesticide products have never been sold or distributed in the 

United States since they were first registered on August 8, 2001. Therefore, no existing stocks 

provisions were necessary for the registrant to sell and distribute their products and no sale or 

distribution of existing stocks was allowed by the cancellation order. 

III. REGISTRATION REVIEW CASE CLOSURE 

As stated in the Preliminary Work Plan for tepraloxydim, the registrant of the only 

then-registered tepraloxydim products recently submitted a request to the Environmental 

Protection Agency (EPA) to voluntarily cancel all of their tepraloxydim product registrations. 

On May 20, 2014, the Agency issued a Notice of Receipt of Request to Voluntarily Cancel 

Certain Pesticide Registrations for tepraloxydim. One comment was received during the 30-day 

comment period from Nippon Soda Co., Ltd. Their comment discussed the importance of 

maintaining the existing tepraloxydim tolerances for importation purposes through 2018. 

Following the public comment period on this request, the Agency decided to grant the 

cancellation of all tepraloxydim product registrations and issue a cancellation order. Therefore, 

due to the cancellation order issued on August 6, 2014, cancelling all tepraloxydim product 

registrations in the United States, the Agency is closing the registration review case for 

tepraloxydim pursuant to 40 CFR §155.42(c) which provides that the Agency "will close a 

registration review case if all products in the case are canceled." 

· Pursuant to 40 CFR §155.42(c), the Agency is closing the registration review case for 

tepraloxydim, thus concluding the Tepraloxydim Registration Review, for the reasons discussed 

above.
