Which option correctly defines bulk pesticides under ATCP 33?

• A. Pesticides stored in any container
• B. Pesticides stored in any outside shed
• C. Liquid pesticides in containers larger than 55 gallons or solid pesticides in undivided quantities greater than 100 pounds
• D. Pesticides labeled "bulk"

Answer: (C)

Bulk pesticides are defined by certain size thresholds that trigger additional storage and handling requirements. Under ATCP 33, a liquid pesticide stored in a container larger than 55 gallons is considered bulk, and a solid pesticide stored in an undivided quantity greater than 100 pounds is also considered bulk. This means that large single containers—whether liquid over 55 gallons or solid in more than 100 pounds—fall under bulk pesticide regulations, with corresponding containment, labeling, and recordkeeping requirements. Smaller quantities in multiple containers don’t meet the bulk definition unless a single container exceeds the thresholds, or the undivided solid quantity is over 100 pounds. Options that rely on location, container count, or labeling alone don’t match how bulk is defined.
