Ill. Admin. Code tit. 35 § 724.275

Current through Register Vol. 48, No. 49, December 6, 2024

Section 724.275 - Containment

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.
