2017-19458. Interim Registration Review Decision for 22 Sulfonylurea Pesticides; Notice of Availability

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice announces the availability of EPA's interim registration review decision for the 22 sulfonylurea herbicide chemicals listed in the Table in Unit II of this Notice. It also announces the case closure for desmedipham (Case 2150 and Docket ID Number: EPA-HQ-OPP-2010-1044), Busan 1024 (case 5026 and Docket ID Number: EPA-HQ-OPP-2006-0243), Bis (trichloromethyl) sulfone (BTS) (Case 2055 and Docket ID Number: EPA-HQ-OPP-2011-0614), Perboric Acid (Case 5007 and Docket ID Number: EPA-HQ-OPP-2012-0006), and profenofos (Case 2540 and Docket ID Number: EPA-HQ-OPP-2008-0345) because all of the U.S. registrations for these pesticides have been canceled. 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, the pesticide can perform its intended function without causing 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.
