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:

   1. (A) The research may involve a hazard to the environment.
   2. (B) The research may be used for purposes unrelated to pesticide data development.
   3. (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.

(h)

1. (1) This section does not apply to the use of a second-generation anticoagulant rodenticide or first-generation anticoagulant rodenticide in either of the following locations:

   1. (A) A medical waste generator, as defined in Section 117705 of the Health and Safety Code.
   2. (B) A facility registered annually and subject to inspection under Section 510 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. Sec. 360 et seq.) and compliant with the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. Sec. 136 et seq.).

2. (2) Consistent with the requirements of this division and regulations adopted pursuant to this division, the department, in consultation with, and with the concurrence of, the Department of Fish and Wildlife, has adopted any additional restrictions that are necessary to ensure a trend of statistically significant reductions in the percentage of wildlife exposed or mean concentration values of detectable levels of second-generation anticoagulant rodenticides or any of their metabolites in tested tissues of a scientifically representative sample of wildlife. These restrictions shall include a requirement to implement sustainable pest management and integrated pest management practices, such as biological control, habitat manipulation, and modification of cultural practices, before the use of second-generation anticoagulant rodenticides. The department, in concurrence with the Department of Fish and Wildlife, shall make a finding that the restrictions are necessary based on the best available science, which may include reviewing data and studying samples of certain species and their populations as proxies for all potentially impacted species and populations.

(j) After the director determines that both of the following conditions have occurred, the director shall certify to the Secretary of State that determination:

1. (1) The department has completed any pending reevaluation of diphacinone.
2. (2) Consistent with the requirements of this division and regulations adopted pursuant to this division, the department, in consultation with, and with the concurrence of, the Department of Fish and Wildlife, has adopted any additional restrictions that are necessary to ensure a trend of statistically significant reductions in the percentage of wildlife exposed or mean concentration values of detectable levels of diphacinone or any of its metabolites in tested tissues of a scientifically representative sample of wildlife. These restrictions shall include a requirement to implement sustainable pest management and integrated pest management practices, such as biological control, habitat manipulation, and modification of cultural practices, before the use of diphacinone. The department, in concurrence with the Department of Fish and Wildlife, shall make a finding that the restrictions are necessary based upon the best available science, which may include reviewing data and studying samples of certain species and their populations as proxies for all potentially impacted species and populations. Substantial evidence supporting the restrictions, including any requirement to implement alternatives, shall, to the extent feasible, include, but not be limited to, analysis regarding exposure pathways, sublethal effects, species sensitivity, and the cumulative and synergistic effects of exposure to anticoagulant rodenticides, including lethal and sublethal effects on wildlife, including rare, sensitive, special status, threatened, or endangered species.
