(a) Issuance. Any person who already has received appropriate approval under FIFRA from U.S. EPA for an experimental use permit that includes experimental use of a pesticide in Guam must apply to the Administrator for an experimental use permit for the pesticide prior to experimental use of the pesticide in Guam. The Administrator may issue an experimental use permit if he determines that the applicant needs such permit in order to accumulate information necessary to register a pesticide under FIFRA or under this Chapter.

(b) Temporary Tolerance Level. If the Administrator determines that the use of a pesticide may reasonably be expected to result in any residue on or in food or feed, he may establish a temporary tolerance level for the residue of the pesticide before issuing the experimental use permit.

(c) Use Under Permit. Use of a pesticide under an experimental use permit shall be under the supervision of the Administrator, and shall be subject to such terms and conditions and be for such period of time as the Administrator may prescribe in the permit.

(d) Studies. When any experimental use permit is issued for a pesticide containing any chemical or combination of chemicals which has not been included, in any previously registered pesticide, the Administrator may specify that studies be conducted to detect whether the use of the pesticide under the permit may cause unreasonable adverse effects on the environment.

of such studies shall be reported to the Administrator before such pesticide may be registered under this Chapter.

(e) Revocation. The Administrator may revoke any experimental use permit, at any time, if he finds that its terms or conditions are being violated, or that its terms or conditions are inadequate to avoid unreasonable adverse effects on the environment.

(f) Permit shall be under the supervision of the Administrator, and shall be subject to such terms and conditions and be for such period of time as the Administrator may prescribe in the permit, including, but not limited to, conditions that require the permittee to obtain written permission of the property owner and the substantial participation in the experimental use by an experienced pesticide researcher approved by the Administrator. All costs involved with the permit process shall be the responsibility of the permittee.
