(1) A person may submit a written application to the Secretary to approve the use of a pesticide in the cultivation of cannabis.

(2) The application shall include a certified risk assessment for the pesticide, performed by an independent accredited laboratory approved by the Secretary, that concludes that the use of the pesticide in the cultivation of cannabis will not lead to unreasonable adverse effects on human health or the environment, after considering the following uses of the pesticide:

(a) On food (in order to have a complete toxicity database to evaluate the potential toxicity of acute, short-term intermediate, and chronic exposure);

(b) On tobacco (in order to have a pyrolysis study to determine the breakdown products formed when the treated plant material is burned);

(c) By the same type(s) of application methods (in order to assess the exposure of workers who mix, load, and apply the pesticides in the cultivation of cannabis);

(d) On crops with agronomic characteristics similar to cannabis in order to ensure that workers handling the pesticide are adequately protected when applying the pesticide; and

(e) In the same kind of structure (e.g., greenhouses or shadehouses) or on the same kind of site (e.g., outdoor dryland site), for the purpose of ensuring that workers handling the pesticide are adequately protected when applying the pesticide, for example, ensuring that the adequate personal protective equipment is required and that the environmental fate and effects of the pesticide use are adequately understood and that any appropriate measures are in place to protect non-target organisms and water resources.

(3) In determining whether the pesticide poses an unreasonable risk to human health, the Secretary shall consult with the Secretary of Health and Mental Hygiene.

(4) The Secretary shall notify the applicant if the request to approve the use of a pesticide in the cultivation of cannabis is granted or denied.
