Bulk Storage Types of Containment

Chemical and Construction Material Compatibility Charts:


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

Dry Products

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.
