This category is for applicators using or supervising the use of any restricted use pesticides purposefully aplied to standing or running water, excluding applicators engaged in public-health-related activities included in Category 8. Performing "aquatic pest control activities" includes, but is not limited to, the use of any pesticide with the intent to prevent, destroy, repel or otherwise mitigate any pest of publicly or privately owned waters, including ponds, lakes, oceans, rivers, streams, reservoirs, and impoundments, whether or not they are navigable, for compensation on the property of another or as a government employee, including the installation of devices. Aquatic pest control activities also includes the soliciting, advertising, or making of sales proposals in any form for any services involving the use of pesticides or devices with the intent to prevent, destroy, repel, or otherwise mitigate any pest of publicly or privately owned waters, including ponds, lakes, oceans, rivers, streams, reservoirs, and impoundments, whether or not they are navigable, for compensation on the property of another.
