What is the required storage/dispensing setback from surface water?

• A. 400 feet
• B. 75 feet
• C. 200 feet
• D. 100 feet

Answer: (B)

The main idea is to protect surface water by keeping pesticide storage and dispensing activities away from it. The required setback is 75 feet, creating a buffer so that spills, leaks, or pesticide wash water are less likely to reach streams, ponds, or other surface water. Measure the distance from the edge of the surface water to the storage or dispensing area, not from the water’s center. This spacing helps prevent contamination from runoff, especially during rain or irrigation, and is a practical, protective standard for most site conditions. If meeting this distance isn’t feasible due to site constraints, additional containment and engineering controls may be needed, and you should consult the relevant pesticide regulatory authority for guidance.
