- Before you repackage bulk pesticides at your facility you must obtain an EPA Establishment number from EPA Region 5. Contact Pamela Grace at 312/353- 2833.
- Facilities that repackage pesticides must report their repackaging or “producing” activities by sending an Annual Production/Repackaging Report to EPA Region 5.
EPA REQUIREMENTS

A permit is required before storing a liquid bulk pesticide product in a storage container with a rated capacity of 500 U.S. gallons or greater or a dry bulk pesticide in a storage container with a rated capacity of 100 lbs. or greater. A permit is also required before a person substantially alters a bulk pesticide facility.
Firms who store bulk pesticides in mini-bulk containers with a rated capacity of less than 500 gallons are not required to obtain a permit, but are required to comply with all other applicable portions of the pesticide storage rules regarding storage and distribution. (Minnesota Rules 1505.3010 - 1505.3150)
PERMIT COMPLIANCE
A permit is required before storing a liquid bulk pesticide product in a storage container with a rated capacity of 500 U.S. gallons or greater or a dry bulk pesticide in a storage container with a rated capacity of 100 lbs. or greater. A permit is also required before a person substantially alters a bulk pesticide facility.
Firms who store bulk pesticides in mini-bulk containers with a rated capacity of less than 500 gallons are not required to obtain a permit, but are required to comply with all other applicable portions of the pesticide storage rules regarding storage and distribution. (Minnesota Rules 1505.3010 - 1505.3150)
- The capacity of the secondary containment area must be a minimum of 110% (roofed storage) of the largest container inside the dike or 125% (unroofed storage) of the largest container inside the dike. Displacement by other tanks in the containment must be calculated as well.
- The secondary containment area must have liquid tight construction, using waterstops, keyways or monolithic concrete pours (pours without joints). Metal containment is acceptable, contact MDA for metal specifications.
- The dike must be maintained to keep its liquid tight integrity. Cracks in the concrete must be sealed with compatible and resistant repair products and metal dikes must be sandblasted and painted on a regular basis to remain free of rust and corrosion. (see the Concrete Containment Crack Repair and Maintenance fact sheet under Forms + Resources.)
- If the safeguard area is a combination dike/load pad, the tanks must be protected from the risk of moving vehicle damage by drive curbs or other vehicle protection devices.
- The secondary containment may not contain a drain or similar opening. If such an opening exists it must be permanently plugged to prevent an incident. Underground plumbing in and through containment floors is not allowed. No other items may breach the secondary containment such as footings or wiring conduits
- A secondary containment system constructed with prefabricated compatible materials (poly tubs, etc.) may be used but must meet all secondary requirements but may not be located in an area where fire could damage the containment.
SECONDARY CONTAINMENT
- The capacity of the secondary containment area must be a minimum of 110% (roofed storage) of the largest container inside the dike or 125% (unroofed storage) of the largest container inside the dike. Displacement by other tanks in the containment must be calculated as well.

- Bulk pesticide tanks that contain pesticides must be stored in a secondary containment or dike area.
- Pesticide storage containers must be constructed, installed, and maintained to prevent the release of liquid or dry bulk pesticide.
- Materials used in the construction or repair of pesticide storage containers must be compatible with the pesticide being stored.
- Appurtenances on storage tanks and plumbing from the tank to and including the first valve must be stainless steel. In some cases where stainless steel is not compatible with a pesticide product or with the tank material such as aluminum, exemptions may be granted from the MDA. An exemption must be requested in writing.
- All bulk pesticide storage tanks must be placed a minimum of one foot from a secondary containment wall.
- Pesticide storage tanks over ten feet high located in outdoor secondary containment must be positioned at least three feet from the secondary containment wall.
- Every pesticide storage container must bear a current pesticide product label as required by the EPA. The label must be complete and readable at all times.
- Bulk pesticide containers must be secured against access by unauthorized persons and protected against access by wildlife. Usually this is accomplished by using fencing (6 foot fencing recommended), by putting the pesticide containers in a locked building, or by ensuring that all tank valves are locked.
- Bulk pesticide containers must be anchored to prevent floatation or instability that may occur as a result of liquid accumulation in the secondary containment area.
- Bulk pesticide containers and appurtenances, including transfer pipes, must be protected against damage caused by moving vehicles.
- Mini-bulk containers are allowed within the secondary containment area, provided that the mini-bulks are elevated equal to the height of the dike wall and are set back at least one foot from the inside the dike wall. These mini-bulk containers (if less than 500 gallons) do not need to be permitted.
PESTICIDE STORAGE TANKS AND APPURTENANCES
- Bulk pesticide tanks that contain pesticides must be stored in a secondary containment or dike area.
- Pesticide storage containers must be constructed, installed, and maintained to prevent the release of liquid or dry bulk pesticide.
- Materials used in the construction or repair of pesticide storage containers must be compatible with the pesticide being stored.

These mini-bulk containers (if less than 500 gallons) do not need to be permitted.
- A load area is required any time a liquid bulk pesticide container is opened and pesticides are transferred from one container to another. This includes filling from a transport truck, filling application equipment from a bulk pesticide container, or using a bulk pesticide container to impregnate fertilizer. Remember, mini-bulk containers are bulk by definition and any time you open a container it must be in containment or on a load area.
- All load areas for liquid bulk pesticide transfers must have a minimum 3 inch curb regardless of its size. A dry pesticide load area does not have to be curbed but must be an elevated flat impermeable surface that is large enough to catch spilled material. Load areas must be constructed in a liquid tight manner. Dive in/out aprons must not exceed 1 foot of length per inch of curb height.
- Load areas must be properly maintained. Cracks in concrete must be repaired with compatible and resistant materials to remain liquid tight. Metal load areas must be kept free of rust and corrosion by regular sandblasting and painting.
- A load area may not contain a drain or similar opening. Any openings must be permanently sealed.
- A load area may be designed with a sump. If a sump will be used, the load area must be sloped to the sump or sediment trap and used only for temporary collection. The sump may not be greater than 2 feet deep or hold more than 109 U.S. gallons.
The minimum required capacity for a liquid bulk pesticide load area is as follows:
| Pesticide Container Size | Required Minimum Load Area Size |
|---|---|
|
Mini-bulk 56 - 249 gallons |
250 gallons |
|
Mini-bulk 250 - 499 gallons |
500 gallons |
|
Bulk tanks 500 gallons or more |
1,000 gallons |
