What must Federal Experimental Use Permits undergo?

Federal Experimental Use Permits are subject to review and registration by both the U.S. Environmental Protection Agency (EPA) and the state Department of Pesticide Regulation (DPR). This is because the use of experimental pesticides can have significant implications for public health and the environment, necessitating a dual layer of oversight to ensure safety and compliance with regulatory standards.

The U.S. EPA is responsible for evaluating whether the experimental use meets federal guidelines and regulations, while state agencies, like DPR, manage additional local considerations and requirements. This collaboration ensures that all potential risks are assessed thoroughly and that the experimental use aligns with both federal and state laws.

The other options do not reflect the requirements accurately; for example, exclusive approval by the U.S. EPA neglects the role of state authorities, and renewal by state authorities alone ignores the necessary federal permit processes. Testing in controlled environments is part of the process but does not encompass the full requirement of regulatory oversight for experimental use, highlighting the complexity involved in the permitting process.
