Which scenario would trigger the requirement for a mixing and loading pad under the Agricultural Chemicals and Groundwater Protection Act?

• A. 4500 lbs dry formulated product
• B. 350 gallons of liquid formulated product
• C. 1000 pounds of active ingredient
• D. 100 gallons of liquid formulated product

Answer: (A)

When pesticides are mixed or loaded, containment is required if you’re handling enough product to pose a spill risk to soil and groundwater. The rule sets a specific quantity threshold to decide when a mixing and loading pad is needed. For dry formulated products, that threshold is reached at 4500 pounds. So handling 4500 pounds of dry formulated product meets the trigger and requires a pad to catch and contain any spills.

The other options don’t meet the threshold: liquids are counted by gallons and, at the given volumes, don’t reach the required level; and the active ingredient amount isn’t the sole trigger unless it corresponds to the product’s formulation and the applicable threshold. In short, the large dry product quantity meets the regulatory threshold, so a mixing/loading pad would be required.
