to meetthe statutorystandard ofno**unreason~ble**adverse effects tohuman health orthe environment. Changes

4II. BACKGROUND INFORMATION Tepraloxydim

is an herbicidal active ingredient with products that were registered for use for postemergence control of certain annual grasses and quackgrass for use on canola, cotton and soybean crops in the United States. Tepraloxydim products were not registered for use on any sites that would result in residential exposure. All registrations
for tepraloxydim have been canceled
as discussed below. 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.
