Ohio Administrative Code
Title 901:5 - Plant Industry
Chapter 901:5-2 - Fertilizer Storage and Handling
Section 901:5-2-03 - Design requirements - bulk liquid fertilizer storage
Universal Citation: OH Admin Code 901:5-2-03
Current through all regulations passed and filed through March 18, 2024
(A) Permanent storage vessels:
(1) Shall be constructed
entirely of materials recommended by the manufacturer or specified in
applicable standards for use with the type of liquid to be stored in the
vessel;
(2) Shall be designed
according to generally accepted engineering standards and practices for liquid
storage vessels and shall take into consideration the full hydrostatic head
pressure, pressure buildup from pumps and compressors, and other mechanical
stresses to which the storage vessel may be subject in the foreseeable course
of operation;
(3) Shall be
equipped with a lockable liquid level gauging device unless another means of
reliably and readily measuring the liquid level of the vessel has been approved
by the director;
(4) Shall be
secured as necessary to prevent flotation or instability as a result of liquid
accumulation within the secondary containment facility;
(5) Shall have stenciled on them in a
location clearly visible in letters no less than four inches in height the
design capacity of the vessel and the identity of its contents;
(6) Shall be equipped with a lockable shutoff
valve.
(B) Appurtenances of permanent storage vessels:
(1) All appurtenances necessary for loading
and unloading shall be located within a secondary containment facility or have
their own means of secondary containment; except hoses and permanent
above-ground piping meeting the requirements of paragraphs (C)(1)(a) to
(C)(1)(e) of rule
901:5-2-11
of the Administrative Code. However, the pipe specified in paragraph (C)(1)(e)
of rule
901:5-2-11
of the Administrative Code does not have to be coated and wrapped.
(2) All hoses used for loading and unloading
shall be equipped with shut-off valves at each end;
(3) All pipes and hoses shall be adequately
supported to prevent sagging and shall be protected against risk of damage by
vehicles engaged in loading and unloading;
(4) All appurtenances shall be made entirely
of materials recommended by the manufacturer or specified in applicable
standards for use with the type of liquid they will carry and the type of
materials used in the vessels and other appurtenances.
(C) Secondary containment facilities for permanent storage vessels:
(1) Shall have a
volumetric capacity of not less than ten per cent greater than the volume of
the largest storage vessel within the secondary containment facility.
Volumetric capacity shall be calculated by multiplying the surface area
enclosed by the dike by the height of the dike minus the volume of the portions
of the other permanent storage vessels within the dike which would be
submerged;
(2) The base of any
permanent storage vessel over fifteen feet in height shall be no less than four
feet from the inside base of the secondary containment facility dike;
(3) The dike and surface area
enclosed within it shall be constructed of materials compatible with the
material they are to contain, be designed to withstand a full hydrostatic head
of any discharged liquids, have a resistance to vertical and horizontal liquid
movement that does not exceed a rate of 1 x 10-5
centimeters per second (thirty-five hundredths of an inch per
day) for the liquids they are to contain and have no open drains.
(D) Notwithstanding the provisions of rule 901:5-2-02 of the Administrative Code, an owner of a permanent storage vessel existing on the effective date of this rule, other than one erected on site, which is located on a farm shall have until January 1, 2007 to comply with the requirements of paragraphs (C)(1), (C)(2), and (C)(3) of this rule.
