BISMARCK, N.D. — North Dakota Agriculture Commissioner Doug Goehring is seeking rules on the containment of liquid fertilizers.

“The proposed language in the containment rules establishes requirements for primary and secondary containment of liquid fertilizer products,” Goehring says. “The requirements for primary containment would cover liquid fertilizer held in undivided quantities greater than 55 gallons. Requirements for secondary containment affect only fertilizer distributors and would apply when liquid fertilizer is held in undivided quantities greater than 2,500 gallons for a period longer than 30 days.”

Primary containment refers to a liquid fertilizer tank and all of the associated hoses, valves and other appurtenances attached to a storage container. Secondary containment refers to structures, such as dikes, that contain spills or releases from a storage container. The proposed rules give distributors several options for secondary containment, including diking, elephant rings, polyurea liners and double-walled tanks.

Goehring urges interested persons and businesses to review and offer comments on the proposed rules, which are available, together with frequently asked questions and answers, on the North Dakota Department of Agriculture website at or by contacting the department.

The deadline for submitting comments is Feb. 13. Goehring has also scheduled a public hearing on the proposed rules for 1 p.m. Feb. 3 in the Brynhild Haugland Room of the State Capitol in Bismarck.
