Section 285.641.4. Primary containment of bulk liquid fertilizer.

(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

§324.8501 et 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.
