Section 285.642.4. Primary containment of bulk liquid fertilizer.

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.
