(3) The department shall evaluate, at a minimum, the potential impacts of the neonicotinoid pesticide uses described in paragraph (2) on pollinating insects, aquatic organisms, and human health, taking into account relevant routes of exposure, as follows:
(A) On or before January 1, 2024, the department shall issue a draft human health risk assessment of imidacloprid.
