This action revises the regulations governing emergency exemptions that allow unregistered uses of pesticides to address emergency pest conditions for a limited time. One change provides applicants for certain repeat exemptions a simple way to re-certify that the emergency conditions that qualified for an exemption in a previous year continue to exist. Another change revises the criteria for determining when a potential emergency condition is expected to cause a significant economic loss and revises the data requirements for documenting the loss. These revisions streamline and improve the application and review process by reducing the burden to both applicants and the Environmental Protection Agency (EPA, or "the Agency"), allowing for potentially quicker decisions by the Agency, and providing for consistent and equitable determinations of "significant economic loss" as the basis for an emergency. This action also includes several minor revisions to the regulations. None of these various improvements compromise protections for human health and the environment.
