Subpart K - ROAD OIL STORAGE AND HANDLING UNITS
Section 616.704 - Design and Operating Requirements for Above-Ground Storage Tanks
Universal Citation: 35 IL Admin Code ยง 616.704
Current through Register Vol. 48, No. 38, September 20, 2024
a) The owner or operator of a tank must not cause or allow:
1)
Materials to be placed in a tank if such materials could cause the tank to
rupture, leak, corrode, or otherwise fail.
2) Uncovered tanks to be placed or operated
so as to maintain less than 60 centimeters (2 feet) of freeboard unless:
A) The tank is equipped with a containment
structure (e.g., dike or trench), a drainage control system, or a diversion
structure (e.g., standby tank); and
B) The containment structure, drainage
control system, or diversion structure has a capacity that equals or exceeds
the volume of the top 60 centimeters (2 feet) of the tank.
3) Material to be continuously fed into a
tank, unless the tank is equipped with a means to stop this inflow (e.g., a
feed cutoff system or a bypass system to a standby tank).
4) Incompatible materials to be placed in the
same tank.
5) Material to be placed
in a tank that previously held an incompatible material unless the incompatible
material has been washed from the tank.
6) Ignitable or reactive material to be
placed in a tank unless:
A) The material is
stored or treated in such a way that it is protected from any material or
conditions that may cause it to ignite or react; or
B) The tank is used solely for
emergencies.
b) The owner or operator must provide and maintain primary containment for the tank such that:
1) The tank has a minimum
shell thickness that ensures that the tank will not fail (e.g., collapse,
rupture).
2) The tank is compatible
with the material to be placed in the tank or the tank is lined with a
substance that is compatible with the material to be placed in the
tank.
c) The owner or operator must provide and maintain secondary containment for the tank that:
1) Is capable of containing the volume of the
largest tank or 10% of the total volume for all tanks, whichever is
greater;
2) Is constructed of
material capable of containing a spill until cleanup occurs (e.g., concrete or
clay). The base of the secondary containment area must be capable of minimizing
vertical migration of a spill until cleanup occurs (e.g., concrete or
clay);
3) Has cover (e.g., crushed
rock or vegetative growth) on earthen embankments sufficient to prevent
erosion; and
4) Isolates the tank
from storm water drains and from combined storm water drains and sanitary sewer
drains.
d) If incompatible materials are handled at the site, secondary containment sufficient to isolate the units containing the incompatible materials must be provided.
e) The owner or operator of a tank must also:
1) Test above-ground
tanks and associated piping every five years for structural
integrity.
2) Remove uncontaminated
storm water runoff from the secondary containment area immediately after a
precipitation event.
3) Handle
contaminated storm water runoff in compliance with 35 Ill. Adm. Code
302.Subpart A.
4) Provide a method
for obtaining a sample from each tank.
5) Install, maintain, and operate a material
level indicator on each tank.
6)
When not in use, lock all gauges and valves that are used to inspect levels in
the tank. All such devices must be located within the containment
structure.
