When does the pesticide bulk storage rule (ATCP33) come into compliance?

The pesticide bulk storage rule (ATCP 33) comes into compliance specifically when a facility stores bulk liquid pesticides in quantities that exceed 55 gallons. This threshold is established to ensure proper handling and safety protocols are in place for larger volumes of potentially hazardous materials. Storing bulk liquids poses a greater risk of spillage and environmental contamination, which is why the regulation targets this specific quantity.

Other options, such as smaller quantities of solid pesticides, do not trigger the bulk storage requirements since the risks associated with smaller amounts are considered manageable within standard safety practices. Similarly, simply having any pesticide stored or maintaining an inventory below 100 pounds does not necessitate compliance with the bulk storage rule, as these situations are deemed to have lower regulatory impact. Thus, adherence to the guidelines surrounding larger quantities of bulk liquid pesticides helps to protect both human health and the environment.
