Exemptions from the requirements discussed in this chapter apply in the following cases:

Containers that hold or have held pesticides registered for spray adjuvant uses are only exempt from the pesticide container rinse and disposal requirements.
Outer shipping containers that have not become contaminated with pesticides are exempt from the pesticide container rinse and disposal requirements.
Check with you local county agricul- tural commissioner if you have any questions regarding these exemptions.
