Mich. Admin. Code R. 285.641.9 - Operational area containment of liquid fertilizer

Rule 9.

(1) A storage facility shall ensure that operational areas are curbed or sloped to allow the containment of accumulated liquids. The storage facility shall construct the area of reinforced concrete or other suitable material approved by the department, to provide an impermeable surface. A storage facility shall ensure that operational area activities at the fertilizer storage facility are carried out within this area.

(2) A storage facility shall construct the operational area containment and reinforce the area to handle at least the foreseeable maximum gross load that could be on the pad.

(3) A storage facility shall comply with all of the following size and capacity requirements for operational area containments:

(a) A storage facility shall ensure that the operational area containment is a minimum width of 10 feet and a minimum length of 20 feet.

(b) A storage facility shall ensure that, except as provided in subdivision (c) of this subrule, curbed surfaces and catch basins are of an adequate size and design to contain a minimum of 1,500 gallons of discharged liquid.

(c) A storage facility shall ensure that if there are no storage containers that are used at the storage facility which have a capacity of more than 1,000 gallons, and if there are no mobile containers that are used to transfer liquid fertilizer to and from storage containers which have a capacity of more than 1,000 gallons, the curbed surface and catch basin are of an adequate size and design to contain 110% of the volume of the largest storage container or the largest mobile container that is used, whichever is greater.

(d) The operational area containment capacity may include an aboveground container for temporary storage if a pump is installed which automatically transfers the contents of the sump into the container and if the container is located within secondary containment.

(4) A storage facility shall ensure that any filling or unloading point of a mobile container is positioned over the paved area during loading or unloading to assure retention of any discharge.

(5) A storage facility shall ensure that the secondary containment area which is described in R 285.641.7 can, under the following conditions, be jointly utilized as an operational containment area instead of a separate operational containment area:

(a) The secondary containment area is not lined with a synthetic or soil liner only.

(b) The storage facility complies with sufficient capacity requirements, R 285.641.7, and this rule.

(6) 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 loading or unloading of bulk fertilizer.

(7) A storage facility shall ensure that loading and unloading operations are supervised at all times by an attendant who is familiar with the operation of the mechanical appurtenances in use at the facility and who is familiar with the procedures that are used for the control and recovery of discharges.

(8) This rule does not apply to a mobile container that is used to nurse field operations when the mobile container is at a field unloading site.

(9) Marine vessels and rail cars are exempt from the operational area containment requirements of this rule if appropriate protective actions are implemented to prevent uncontained discharges and are in compliance with applicable United States coast guard and department of transportation regulations.

(10) 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.
