During a 12-month period, you must mix or load pesticides over an impervious spill containment surface if you exceed how many pounds of active ingredients?

• A. 500 lbs
• B. 1000 lbs
• C. 1500 lbs
• D. 2000 lbs

Answer: (C)

The key idea is knowing the trigger for using an impervious spill containment surface when mixing or loading pesticides. In a 12-month period, this requirement kicks in once you exceed 1,500 pounds of active ingredients. So, the correct threshold to start using the impervious surface is 1,500 pounds. Staying at or below that amount doesn’t require the extra containment, while larger amounts also fall under the same rule—it's the first point at which the rule applies. The other numbers are simply lower or higher than the trigger and don’t define when the requirement begins.
