Minor Crop Protection Assistance Act of 1992

Minor Crop Protection Assistance Act of 1992 - Amends the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to define "minor use" as the use of a pesticide on a commercial agricultural crop or site where: (1) the total U.S. acreage for the crop is less than 300,000 acres; (2) the acreage expected to be treated as a result of that use is less than 300,000 acres annually or the agricultural crop represents production from less than 300,000 acres annually; (3) the use does not provide sufficient economic incentive to support initial or continuing registration; and (4) the Administrator of the Environmental Protection Agency (EPA) has not determined that the use presents an unreasonable adverse environmental effect.

Permits the Administrator, in handling the registration of a pesticide for a minor use, to waive applicable data requirements if determined that the absence of data will not prevent the Administrator from determining the incremental risk presented by the minor use and that such risk would have an unreasonable adverse environmental effect.

Prohibits data that relates solely to a minor use, without the permission of the original data submitter, from being considered by the Administrator to support a minor use application by another person for ten years following the submission of the data. Terminates the exclusive use of such data if the registration is voluntarily cancelled or if the data are used to support a nonminor use.

Provides for expedited review (within six months of submission) of applications to support minor use pesticide registrations.

Grants registrants who make good faith requests for minor use waivers regarding required data and whose requests are denied a full time period for providing such data.

Requires the Administrator, upon the request of a registrant, to extend the deadline for the production of data required solely to support a minor use pesticide up to four years if the registrant provides data to support other uses of the pesticide and a schedule to assure that the data production will be completed before the expiration of the extension. Applies the same extension conditions to data for reregistrations.

Requires the Administrator to conditionally amend a registration to permit additional minor uses even if data is insufficient if the applicant has submitted satisfactory data pertaining to the proposed minor use and amending such registration would not increase environmental risks. Prohibits amendments if the pesticide meets or exceeds risk criteria associated with human dietary exposure and other specified conditions.

Provides for extensions of minor use registration and data submission deadlines in cases where a registrant is not providing data to support a minor use but is providing data in a timely fashion to support other uses.

Requires the Administrator, when a minor use registration application is filed no later than two years after another registrant voluntarily cancels registration for a similar use, to evaluate such application as if the voluntary cancellation had not yet taken place for purposes of data use, subject to environmental risk considerations.

Directs the Administrator to assure coordination of minor use issues through the establishment of a minor use program within the Office of Pesticide Programs.

Establishes and authorizes funding for a Department of Agriculture matching fund minor use program. Requires the program to be used to ensure the continued availability of minor use crop protection chemicals, including the data to support minor use pesticide registrations.
