No secondary containment requirements for bulk liquid
fertilizer on farms. An attempt for new rules for on-
farm storage failed this year.
Up to 5,000 (total volume) does not need secondary
containment. Anything over 5,000 (total volume) does
need secondary containment.
New On-farm storage rules were adopted in 2003. Rules apply to farmers storing over 30 days in tanks greater than 2,500 gallons or a combined
total of greater than 7,500 gallons. (Being phased in
over a five year period.)
No secondary containment requirement for on-farm bulk
liquid fertilizer storage.
No secondary containment regulations of any kind; farmers or
dealers

2. Tanks and appurtenances in good condition
3. No storage adjacent to wells, surface waters, tile inlets or anything easily contaminated from a spill
3. Store and handle in a manner that won't cause environmental problems
4. Storing closer than 150 to a well, tile inlet, surface inlet or surface water
5. Storing in an area where the water table is less than 6 feet deep
