a) Container
storage areas must have a containment system that is designed and operated in
accordance with subsection (b), except as otherwise provided by subsection
(c);
b) A containment system must
be designed and operated as follows:
1) A base
must underlie the containers that is free of cracks or gaps and is sufficiently
impervious to contain leaks, spills, and accumulated precipitation until the
collected material is detected and removed.
2) The base must be sloped or the containment
system must be otherwise designed and operated to drain and remove liquids
resulting from leaks, spills, or precipitation, unless the containers are
elevated or are otherwise protected from contact with accumulated
liquids;
3) The containment system
must have sufficient capacity to contain 10 percent of the volume of containers
or the volume of the largest container, whichever is greater. Containers that
do not contain free liquids need not be considered in this
determination;
4) Run-on into the
containment system must be prevented, unless the collection system has
sufficient excess capacity in addition to that required in subsection (b)(3) to
contain any run-on that might enter the system; and
5) Spilled or leaked waste and accumulated
precipitation must be removed from the sump or collection area in as timely a
manner as is necessary to prevent overflow of the collection system.
BOARD NOTE: If the collected material is a hazardous waste,
it must be managed as a hazardous waste in accordance with all applicable
requirements of 35 Ill. Adm. Code 722 through 728. If the collected material is
discharged through a point source to waters of the State, it is subject to the
National Pollution Discharge Elimination System (NPDES) permit requirement of
Section 12(f) of the Environmental Protection Act and 35 Ill. Adm. Code
309.102.
c) Storage areas that
store containers holding only wastes that do not contain free liquids need not
have a containment system defined by subsection (b), except as provided by
subsection (d), or provided as follows:
1)
That the storage area is sloped or is otherwise designed and operated to drain
and remove liquid resulting from precipitation, or
2) That the containers are elevated or are
otherwise protected from contact with accumulated liquid.
d) Storage areas that store containers
holding the wastes listed below that do not contain free liquids must have a
containment system defined by subsection (b): F020, F021, F022, F023, F026, and
F027.
