Bulk Storage Types of Containment

All liquid pesticides and fertilizers need to be stored in containers (tanks) resistant to corrosion, puncture, and cracking.
While the tank itself is essential as a safeguard from potential releases, all bulk liquid tanks must be within a diked area. The dike must be able to hold 110% of the largest tank's volume, plus a six-inch volume of rainfall, and the displacement of other tanks below the wall.
Types of containment materials include:
- Sealed concrete
- Fabricated steel
- Synthetic lined or clay lined earthen berm (fertilizer only)
- Concrete, modular concrete block, fiberglass, or treated lumber frame w/synthetic liner
To prevent any runoff or leaching of agrichemicals, all operations need to be conducted on a mix/load pad.
The mix/load pad must have:
- An impermeable surface
- Minimum dimensions of 10' by 20'
- At least a 1,500 gallon capacity
Although bulk dry products do not require secondary containment, products need to be stored in a building or structure that prevents contact with precipitation and surface water.
