Current through Register Vol. 49, No. 6, March 15, 2024
PURPOSE: This rule specifies the minimum standards
for the design of agrichemical facilities. It does not address all aspects of
design, and the design engineer may refer to other appropriate reference
materials so long as these minimum standards set forth in this rule are
met.
PUBLISHER'S NOTE: The secretary of state has
determined that the publication of the entire text of the material which is
incorporated by reference as a portion of this rule would be unduly cumbersome
or expensive. This material as incorporated by reference in this rule shall be
maintained by the agency at its headquarters and shall be made available to the
public for inspection and copying at no more than the actual cost of
reproduction. This note applies only to the reference material. The entire text
of the rule is printed here.
(1) Applicability. This rule applies to all
agrichemical facilities and to the construction of new secondary and
operational containment of agrichemicals at existing facilities. All facilities
to which this rule applies shall be designed as no-discharge systems.
(2) Exceptions.
(A) The prohibition of storing bulk liquid
fertilizer in a mobile container for more than thirty (30) days shall not apply
to barges and rail cars used solely for transporting liquid fertilizer from
chemical production facilities to retail or wholesale facilities.
(B) The prohibition of burying pipes used for
transferring full strength agrichemicals shall not apply to piping used solely
for the loading and unloading of liquid fertilizer from barges and rail cars.
These pipes shall be pressure tested on a yearly basis to certify the integrity
of the pipes. Records of the pressure testing shall be kept on file at the
facility and made available to Missouri Department of Natural Resources
(department) personnel upon request.
(C) Liquid fertilizer storage tanks that were
in use prior to January 13, 1992, having a storage capacity greater than forty
thousand (40,000) gallons are exempt from the requirement of installing a liner
underneath the tank itself. Spill containment diking is required around these
tanks.
(3) Engineering
Report. An engineering report is required for all facilities required by
10 CSR
20-6.010 to submit an application for a construction
permit.
(4) Primary Containment
for Bulk Liquid Agrichemicals for new construction. Containers and
appurtenances used as the primary containment in the storage and handling of
bulk agrichemicals shall be constructed, installed, and maintained to prevent a
discharge and shall be of materials and construction compatible with the
specifications of the product stored with:
(A) Tank anchors or raised stands;
(B) For self-supporting tanks, the ability to
handle all operating stresses, hydrostatic head, pressure buildup from pumps
and compressors and any other mechanical stresses to which the containers and
appurtenances may be subject to in the foreseeable course of

(B) No discharge outlet or gravity drain
through the wall or floor of the containment structure;
(C) The walls and floors constructed of

that would result from a massive spill within the containment
structure;
(D) Expansion joints
spaced to prevent cracks from forming; sealed with a material resistant to
agrichemicals; and with water stops installed between the containment walls and
floor;
(E) A collection sump, if
needed, shall not be more than two feet (2') deep or larger than twenty (20)
cubic feet; constructed of materials that resist penetration by moisture and
agrichemicals; with a sealed connection point between the containment area
floor; and at a low point in the containment area to allow for removal of
accumulated liquids;
(F) No piping
installed through the walls or floor except for through common, interconnecting
containment walls and all piping entering and leaving the secondary containment
structure shall go up and over the containment walls;
(G) No buried transfer piping;
(H) Separation of bulk liquid pesticides and
bulk liquid fertilizers with a common wall and with no interconnecting piping;
and
(I) All auxiliary tanks for
storage of rinsate or precipitation collected in the secondary or operational
containment area located within a secondary containment structure.
(J) Earthen structures used for secondary
containment shall be designed as follows:
1.
Be constructed with a compacted soil liner or synthetic liner with a
permeability rate of 1 x 10-7 cm/sec. or less.
2. Be protected against erosion
with side slopes no steeper than three to one (3:1) and with a top width no
less than two and one-half feet (2 1/2').
(6) Nonmobile bulk dry fertilizer storage
shall be designed to-
(A) Be stored inside a
sound structure to prevent contact with precipitation with all surface water
runoff diverted away from the storage structure;
(B) Allow for all unloading, loading, mixing,
and handling of dry bulk fertilizers to be done on an operational containment
area as required in section (9) of this rule;
(C) Have an adequately sized operational

equipment as required in section (9) of this rule;
(D) Allow for daily cleanup of the dry
fertilizer loading, unloading, mixing, and handling areas;
(E) Prevent the downward movement of
