Current through Vol. 24-12, July 15, 2024
Rule 4.
(1) A
				storage facility shall ensure that a storage container and an appurtenance are
				constructed, installed, and maintained to prevent the unintentional discharge
				of fluid fertilizer.
(2) A storage
				facility shall ensure that a storage container and an appurtenance are
				constructed of materials that are resistant to corrosion, puncture, or
				cracking.
(3) A storage facility
				shall ensure that metals which are used for valves, fittings, and repairs on
				metal containers are 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) A storage facility shall ensure that a
				storage container and an appurtenance are 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) A storage facility shall ensure that a
				storage container and an appurtenance, including pipes, are protected against
				reasonably foreseeable risks of damage by trucks and other moving vehicles that
				are engaged in the handling of bulk fertilizers.
(6) A storage facility shall ensure that a
				storage container and an appurtenance are constructed of materials that are
				compatible with the product or products being stored and handled.
(7) A storage facility shall ensure that a
				storage container is not filled beyond the capacity for which it is designed,
				taking into account the physical characteristics of the fluid that is being
				stored.
(8) A storage facility
				shall ensure that flexible connections and properly supported appurtenances are
				utilized as dictated by engineering practices to reduce vibrational and
				stress-related deterioration.
(9) A
				storage facility shall ensure that backflow protection or a fixed air gap is
				utilized to protect water lines as required by standard engineering and
				plumbing practices.
(10) A storage
				facility shall locate primary containment piping above the ground and within
				secondary containment. The end of primary containment piping or any manifold
				device shall remain within secondary containment. Underground primary
				containment piping is permitted provided the piping is made of stainless steel,
				is enclosed in secondary containment (a pipe within a pipe) or is
				hydrostatically tested annually.
(11) A storage facility shall ensure that a
				storage container is anchored, elevated, or secured by some other means as
				necessary to prevent flotation or instability.
(12) A storage facility shall locate mobile
				storage container that contains liquid fertilizer 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) A storage
				facility shall ensure that an adequate distance to allow for inspection and
				maintenance is maintained between storage containers and between storage
				containers and the secondary containment wall.
(15) A facility that has an existing
				secondary containment area on the effective date of this rule which does not
				provide adequate distance to allow for inspection and maintenance shall provide
				an adequate distance when a physical change to a storage container or the
				secondary containment takes place.
(16) A storage facility shall ensure that a
				bulk fertilizer storage container is labeled in a prominent location with
				lettering that is a minimum of 4 inches in height. In addition to meeting the
				provisions of Act No. 451 of the Public Acts of 1994, as amended, being §
									324.8501et
				seq.of the Michigan Compiled Laws, a storage facility shall ensure that the
				labeling includes the capacity of the storage container.
(17) A facility that is placed in service
				after the effective date of this rule shall immediately comply with this rule.
				A facility that is in service before the effective date of this rule has 2
				years to comply with this rule.
