Start Preamble


Environmental Protection Agency (EPA).




This notice announces the availability of EPA's proposed interim registration review and opens a 60-day public comment period on the proposed interim decisions. It also opens the docket for Bacillus thuringiensis. 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, that the pesticide can perform its intended function without 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.

The registration review docket for a pesticide includes earlier documents related to the registration review case, except for Bacillus thuringiensis, whose docket is now opening. For example, the review opened with a Summary Document, containing a Preliminary Work Plan, for public comment. A Final Work Plan was placed in the docket following public comment on the Preliminary Work Plan.

The documents in the dockets describe EPA's rationales for conducting additional risk assessments for the registration review of the pesticides included in the tables in Unit II, as well as the Agency's subsequent risk findings and consideration of possible risk mitigation measures. These proposed interim registration review decisions are Start Printed Page 45479supported by the rationales included in those documents.

Following public comment, the Agency will issue interim or final registration review decisions for the pesticides listed in the tables in Unit II.

The registration review program is being conducted under congressionally mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public. Section 3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136a(g)) required EPA to establish by regulation procedures for reviewing pesticide registrations, originally with a goal of reviewing each pesticide's registration every 15 years to ensure that a pesticide continues to meet the FIFRA standard for registration. The Agency's final rule to implement this program was issued in August 2006 and became effective in October 2006, and appears at 40 CFR part 155, subpart C. The Pesticide Registration Improvement Act of 2003 (PRIA) was amended and extended in September 2007. FIFRA, as amended by PRIA in 2007, requires EPA to complete registration review decisions by October 1, 2022, for all pesticides registered as of October 1, 2007.

The registration review final rule at 40 CFR 155.58(a) provides for a minimum 60-day public comment period on all proposed interim registration review decisions. This comment period is intended to provide an opportunity for public input and a mechanism for initiating any necessary amendments to the proposed interim decision. All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. These comments will become part of the docket for the pesticides included in the tables in Unit II. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

The Agency will carefully consider all comments received by the closing date and may provide a “Response to Comments Memorandum” in the docket. The interim registration review decision will explain the effect that any comments had on the interim decision and provide the Agency's response to significant comments.

Background on the registration review program is provided at:​pesticide-reevaluation.
