II. Background

What Action is the Agency Taking?

Under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (7 U.S.C. 136p), at the discretion of the Administrator, a Federal or State agency may be exempted from any provision of FIFRA if the Administrator determines that emergency conditions exist which require the exemption. The Oregon Department of Agriculture has requested the Administrator to issue a specific exemption for the use of quinoclamine on greenhouse ornamentals to control liverwort. Information in accordance with 40 CFR part 166 was submitted as part of this request.

As part of this request, the Applicant asserts that liverwort infestations are becoming more severe in Oregon, resulting in crop losses and difficulty for many operations to grow their crop successfully. Entire crops can be rejected due to suspicion that liverwort spores are infesting the crop. There are currently no chemical controls registered for this use, and the Applicant asserts that quinoclamine can reliably remove liverwort and its propagules from a containerized plant. Economic losses can occur due to the following:

1. The excessive costs for hand weeding,

2. Failure of plants to grow or thrive, and

3. Losses from reduced quality or outright rejection of crops sold from one nursery to another. The Applicant states that significant economic losses will be suffered without the requested use.

The Applicant proposes to make no more than 4 applications of quinoclamine, on up to 600 acres of greenhouse area in the state of Oregon. The use would potentially occur year-round, and a total of up to 65,400 lbs. of formulated product (16,350 lb. active ingredient) could be used under this exemption, if authorized.

This notice does not constitute a decision by EPA on the application itself. The regulations governing section 18 of FIFRA require publication of a notice of receipt of an application for a specific exemption proposing use of a new chemical (i.e., an active ingredient) which has not been registered by the EPA. The notice provides an opportunity for public comment on the application.

The Agency, will review and consider all comments received during the comment period in determining whether to issue the specific exemption requested by the Oregon Department of Agriculture.
