SUPPLEMENTARY INFORMATION:

I. Purpose of This Notice

Pursuant to 40 CFR 155.58(a), this notice announces the availability of EPA's proposed interim registration review decision for pyrimethanil (Table 1) and opens a 60-day public comment period on the proposed interim decision.

II. Background

EPA is conducting its registration review of pyrimethanil pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) section 3(g) (7 U.S.C. 136a(g)) and the Procedural Regulations for Registration Review at 40 CFR part 155, subpart C. FIFRA Section 3(g) provides, among other things, that pesticide registrations are to be reviewed every 15 years. Consistent with 40 CFR 155.57, in its final registration review decision, EPA will ultimately determine whether a pesticide continues to meet the registration standard in FIFRA section 3(c)(5) (7 U.S.C. 136a(c)(5)). As part of the registration review process, the Agency has completed a proposed interim decision for the pesticide listed in Table 1 of Unit I.

The registration review docket for a pesticide includes documents related to the registration review case. Among other things, these documents describe EPA's rationales for conducting additional risk assessments for the registration review of the pesticide included in Table 1 of Unit I, as well as the Agency's subsequent risk findings and consideration of possible risk mitigation measures. The proposed interim registration review decision is supported by the rationales included in those documents.

Consistent with 40 CFR 155.58(a), EPA provides for at least a 60-day public comment period on 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 decision.

This notice 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.
