Current through Vol. 24-12, July 15, 2024
Rule 4.
(1) Storage
				containers and appurtenances shall be constructed, installed, and maintained to
				prevent the unintentional discharge of fluid fertilizer.
(2) Storage containers and appurtenances
				shall be constructed of materials that are resistant to corrosion, puncture, or
				cracking.
(3) Metals that are used
				for valves, fittings, and repairs on metal containers shall be compatible with
				the metals that are used in the construction of the storage container so that
				the combination of metals does not cause or increase corrosion which may weaken
				the storage container or its appurtenances or create a risk of
				discharge.
(4) Storage containers
				and appurtenances shall be designed to handle all operating stresses, taking
				into account static head, pressure buildup from pumps and compressors, and any
				other mechanical stresses to which the storage containers and appurtenances may
				be subject in the course of operations.
(5) Storage containers and appurtenances,
				including pipes, shall be protected against reasonably foreseeable risks of
				damage by trucks and other moving vehicles that are engaged in the handling of
				bulk fertilizers.
(6) Storage
				containers and appurtenances shall be constructed of materials that are
				compatible with the product or products being stored and handled.
(7) Storage containers shall not be filled
				beyond the capacity for which they are designed, taking into account the
				physical characteristics of the fluid that is being stored.
(8) Flexible connections and properly
				supported appurtenances shall be utilized as dictated by standard engineering
				practices to reduce vibrational and stress-related deterioration.
(9) Backflow protection or a fixed air gap
				shall be utilized to protect water lines as required by standard engineering
				and plumbing practices.
(10)
				Primary containment piping shall be located above the ground and within
				secondary containment. The end of primary containment piping or any manifold
				device shall remain within secondary containment.
(11) Storage containers shall be anchored,
				elevated, or secured by some other means as necessary to prevent flotation or
				instability.
(12) Mobile storage
				containers that contain liquid fertilizer shall be stored not less than 100
				feet from a water well or surface water.
(13) A person shall not store liquid
				fertilizer in a container that is located underground.
(14) An adequate distance to allow for
				inspection and maintenance shall be maintained between storage containers and
				between storage containers and the secondary containment wall.
(15) Facilities that have existing secondary
				containment areas on the effective date of this rule which do not provide
				adequate distance to allow for inspection and maintenance, shall provide this
				distance at the time any physical changes to storage containers or the
				secondary containment takes place.
(16) Storage containers shall be labeled as
				fertilizer in order to identify the contents within. The storage container
				labeling shall be in a prominent location with lettering that is a minimum of 4
				inches in height.
