According to Regulation 640, which condition would require a facility to register with the MDA?

A facility is required to register with the Michigan Department of Agriculture (MDA) when storing pesticides in bulk greater than 55 gallons. This regulation is in place to ensure that larger quantities of pesticides are stored safely and that there is oversight of the facilities that handle potentially hazardous chemicals.

When the quantity of stored pesticides surpasses a certain threshold, such as 55 gallons, it triggers regulatory requirements concerning safety protocols, containment measures, and environmental protections. Registration allows for proper tracking and management of these substances, which is vital for preventing accidents and protecting both worker safety and the environment.

The other conditions listed do not meet the registration requirements as outlined by the regulation. For instance, storing fewer than 55 gallons does not raise the same level of regulatory concern, and storing pesticides in open containers presents different risks, but may not specifically trigger the registration threshold as indicated by the regulation's focus on bulk storage. Additionally, distributing only ready-to-use products does not necessitate registration either, as this involves a different set of handling and distribution standards rather than storage volume.
