The use of a second-generation anticoagulant rodenticide or first-generation anticoagulant rodenticide for research purposes related to the reevaluation described in paragraph (1) of subdivision (i), paragraph (1) of subdivision (j), or paragraph (1) of subdivision (k). Before using a second-generation anticoagulant rodenticide or first-generation anticoagulant rodenticide in the manner described in this paragraph, a written authorization for research shall be obtained from the director. The director may specify the conditions in the authorization for research under which the research shall be conducted. The director may terminate, amend, or refuse to issue an authorization for research if the director determines any of the following:
(A)
The research may involve a hazard to the environment.
(B)
The research may be
used for purposes unrelated to pesticide data development.
(C)
A violation of the authorization for research, prior authorization for research, or Division 6 (commencing with Section 11401) or this division, or a regulation adopted pursuant to either or both of those divisions, has occurred in connection with the research.
