I. General Information

This action is directed to the public in general and may be of interest to a wide range of stakeholders including environmental, human health, farm worker, and agricultural advocates; the chemical industry; pesticide users; and members of the public interested in the sale, distribution, or use of pesticides. Since others also may be interested, the Agency has not attempted to describe all the specific entities that may be affected by this action. If you have any questions regarding the applicability of this action to a particular entity, consult the pesticide specific contact person listed under FOR FURTHER INFORMATION CONTACT.

II. Background

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 unreasonable adverse effects on human health or the environment. As part of the registration review process, the Agency has completed interim decisions for all pesticides listed in the Table in Unit IV. 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.

III. Authority

EPA is conducting its registration review of the chemicals listed in the Table in Unit IV pursuant to section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Procedural Regulations for Registration Review at 40 CFR part 155, subpart C. Section 3(g) of FIFRA provides, among other things, that the registrations of pesticides are to be reviewed every 15 years. Under FIFRA, a pesticide product may be registered or remain registered only if it meets the statutory standard for registration given in FIFRA section 3(c)(5) (7 U.S.C. 136a(c)(5)). When used in accordance with widespread and commonly recognized practice, the pesticide product must perform its intended function without unreasonable adverse effects on the environment; that is, without any unreasonable risk to man or the environment, or a human dietary risk from residues that result from the use of a pesticide in or on food.

IV. What action is the agency taking?

Pursuant to 40 CFR 155.58, this notice announces the availability of EPA's interim registration review decisions for the pesticides shown in the following table. The interim registration review decisions are supported by rationales included in the docket established for each chemical.

The proposed interim registration review decisions for the chemicals in the table above were posted to the docket and the public was invited to submit any comments or new information. EPA addressed the comments or information received during the 60-day comment period for the proposed interim decisions in the discussion for each pesticide listed in the table. Comments from the 60-day comment period that were received may or may not have affected the Agency's interim decision. Pursuant to 40 CFR 155.58(c), the registration review case docket for the chemicals listed in the Table will remain open until all actions required in the interim decision have been completed.

This document also announces the posting of the amended interim decisions for ethalfluralin and hexazinone. The original interim decision for ethalfluralin was published on December 15, 2017 (82 FR 59606) (FRL-9970-54) and the original interim decision for hexazinone as published on February 27, 2018 (83 FR 8472) (FRL-9973-09). Following issuance of these decisions, the agency received information that resulted in it amending the required label modifications. These modifications are expected to allow applicators greater flexibility, while not affecting the agency's overall risk management determinations.

This document also announces the closure of the registration review case for triforine (Case 2720, Docket ID Number EPA-HQ-OPP-2015-0853) because the last U.S. registrations for this pesticide have been canceled. Background on the registration review program is provided at: http://www.epa.gov/​pesticide-reevaluation.
