(a) On or before July 1, 2018, the department shall issue a determination with respect to its reevaluation of neonicotinoids.(b) (1) Within two years after making the determination specified in subdivision (a), the department shall adopt any control measures necessary to protect pollinator health.
(2) If the department is unable to adopt the necessary control measures within two years as required in paragraph (1), the department shall submit a report to the appropriate committees of the Legislature setting forth the reasons the requirement of paragraph (1) has not been met.
(3) The department shall update the report submitted to the appropriate committees of the Legislature pursuant to paragraph (2) every year until the department adopts the necessary control measures specified in paragraph (1).
(c) (1) For purposes of this subdivision, “neonicotinoid pesticide” means a pesticide containing acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxam, or any other chemical designated by the department as belonging to the neonicotinoid class of chemicals. the following definitions apply:
(A) “Cumulative impacts of exposure” means the impact of exposure to two or more neonicotinoid chemicals in the outdoor lawn or garden environment, aggregated with the impacts of exposure to any relevant neonicotinoid chemicals from sources other than lawn or garden products.
(B) “Neonicotinoid pesticide” means a pesticide containing acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxam, or any other chemical designated by the department as belonging to the neonicotinoid class of chemicals.
(2) (A) On or before July 1, 2024, the department shall
issue a determination, taking into account the latest science, with respect to a reevaluation of neonicotinoids neonicotinoid pesticides when used on outdoor
ornamental plants, trees, and turf.
(B) All of the following apply to the reevaluation:
(i) The reevaluation shall consider the impacts of neonicotinoid pesticides on pollinating insects, aquatic ecosystems, and human health.
(ii) In performing the reevaluation, the department shall consider the cumulative impacts of exposure to multiple neonicotinoid pesticides unless the department can demonstrate with substantial evidence that one or more neonicotinoid pesticides do not share a common mechanism of toxicity and do not present risk of cumulative harm. For purposes of this subdivision, “cumulative impacts of exposure” means the impact of exposure to two or more neonicotinoid chemicals in the outdoor lawn
or garden environment, aggregated with the impacts of exposure to any relevant neonicotinoid chemicals from sources other than lawn or garden products.
(iii) The department is not required to conduct a reevaluation of any use of neonicotinoid pesticides for the protection of agricultural commodities, as defined in Section 6000 of Title 3 of the California Code of Regulations.
(3) On or before July 1, 2026, the department shall adopt any
control measures for the use of neonicotinoid pesticides on outdoor ornamental plants, trees, and turf that are necessary determined by the department to be necessary, based on the reevaluation described in paragraph (2), to protect all of the following:
(A) Pollinating insects, including honeybees and native bees, taking into account all relevant routes of exposure, including exposure to contaminated pollen, nectar, soil, and water.
(B) Aquatic ecosystems, taking into account contamination of surface or ground water.
(C) Human
health, taking into account the cumulative exposure of people to neonicotinoid pesticides from all sources.
