Your mixing and loading pad should at least have the following features.
- Containing pesticide spills and leaks requires an impermeable
(waterproof) surface for mixing and loading. The pad should be large
enough to contain leaks from bulk tanks, wash water from cleaning
equipment, and spills from transferring pesticides to the sprayer or
spreader.
- The size of the pad depends also on the equipment you use. It
should provide space around the parked equipment for washing and
rinsing. Having several separate storage tanks allows you to keep
rinsewater from different chemicals separate. That way, it can be
used as mixing water on subsequent loads of the same chemical.
- Locate the pad next to the storage area. Make sure that any water
from the pad moves away from any well. At sites where runoff water
could reach a well, construct a diversion so runoff is directed to
another area.
