I Part 3.0 B - Mixing and Loading Areas for Liquid Fertilizer
All mixing and loading area operations for liquid fertilizers must take place on a pad that meets the following requirements:
3.6. Capacity
The mixing and loading pad shall provide at least the following capacity:
(a) The pad shall
be of adequate size and design to contain 125% of the volume of the largest
container to be loaded or unloaded if unprotected from precipitation or 110% of
the volume of the largest container to be loaded or unloaded if protected from
precipitation.
(b) If any storage
container or mobile container to be loaded or unloaded has a capacity of
greater than 1200 gallons the containment volume need only be large enough to
hold a minimum of 1500 gallons if unprotected from precipitation or 1320
gallons if protected from precipitation. If the primary use of the pad is to
load and unload spray equipment and associated support vehicles and bulk
transport vehicles use the pad only for occasional delivery of fertilizers then
the pad size shall be determined by the volume of the largest container on the
spray equipment or support vehicles provided the pad is designed so that bulk
transport vehicles can conduct their occasional operations with all their
appurtenances over the pad.
3.7. Fertilizer discharges or precipitation
accumulations on a mixing and loading pad shall be immediately recovered such
that the capacity listed in paragraph 3.6(a) is available at all times.
Fertilizer material recovered shall be utilized for its original intended
purpose. The facility shall have items on hand and readily available to recover
discharges to the maximum extent possible.
3.8. General Requirements
(a) Provided the required containment
capacity of 3.6 (a) is met, pads need only be large enough so that the tank and
appurtenances are physically over the pad provided no flushing of the boom
system occurs.
(b) Pads for mixing
and loading areas shall be constructed of reinforced concrete or other material
so as to form an impervious barrier between the fertilizer handling area and
the surrounding earth.
(c) The
mixing and loading pad shall be designed to prevent storm water runoff from
moving onto or across the mixing and loading pad.
(d) The mixing and loading pad shall not have
any outlet points.
(e) The pad
shall be constructed to a permeability rate that does not exceed 1 x 10-7
centimeters per second (~0.0035 inches per day) or a citation provided that
identifies a material's specification that when followed will provide an
equivalent permeability.
(f) The
pad must be maintained as impervious for the usable life of the
structure.
(g) The pad must be able
to handle the wheel loads of any vehicles using it.
(h) Mixing and loading pads shall be designed
to drain liquids to a sump.
(i)
Sumps shall be drained only by a manually activated pump during the operating
season of the facility. Automatic pumps may be used during the inactive
season.
(j) Sumps shall be
constructed of materials which resist corrosion or are treated to resist
corrosion from fertilizers.
(k)
Rail cars unloading liquid fertilizer at bulk fertilizer storage facilities are
not required to meet the provisions of ¶ 3.6 and ¶ 3.8 (a)-(j)
provided adequate catch basins are placed under the valves to recover drips and
leaks.
