Farmers who own their own portable, refillable pesticide containers, commonly known as mini-bulk tanks, must meet federal requirements in effect since last August.
Tank owners are responsible for ensuring their tanks meet the U.S. Environmental Protection Agency (EPA) standards. If a container doesn’t meet the requirements, agrichemical dealers legally cannot fill it.
Recently, EPA clarified steps needed by individuals who own mini-bulk tanks, according to Jean Payne, president of the Illinois Fertilizer and Chemical Association (IFCA). This spring and summer, the Illinois Department of Agriculture will be checking for compliance of these EPA regulations, Payne said.
The type of tank must be listed on a pesticide management approved list. Ask your local retailer to check the list.
The tank must meet Department of Transportation (DOT) requirements. Tanks that meet those requirements have a UN/DOT marking usually stamped on them.
The tank must be leak-proof tested every two and a half years after it was manufactured. The tank owner is responsible for the testing. Instructions on how to test a tank are available on the IFCA website
or view the Powerpoint display listed below.
A tank must have a unique identification number, such as a serial number or other unique identification. Tank owners may make their own identification number as long as it is unique, according to Payne.
The identification number may be written in indelible ink on the tank or on an adhesive label that is attached to the tank.
Tanks must have either a tamper-evidence device or a one-way valve. Payne noted tank owners may prefer one-way valves because any tank with a tamper-evidence device that is later opened to remove the product must be cleaned before it can be refilled by a retailer.
Tanks must be properly labeled for the product.
