Section 664.0175. Containment.

 

(1)  Container storage areas shall have a containment system that is designed and operated in accordance with sub. (2) , except as otherwise provided by sub. (3) .

(2)  A containment system shall be designed and operated to meet all of the following requirements:

(a) A base shall underlie the containers which 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.

(b) The base shall be sloped or the containment system shall 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.

(c) The containment system shall have sufficient capacity to contain 10% 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.

(d) Run-on into the containment system shall be prevented unless the collection system has sufficient excess capacity in addition to that required in par. (c) to contain any run-on which might enter the system.

(e) Spilled or leaked waste and accumulated precipitation shall be removed from the sump or collection area in as timely a manner as is necessary to prevent overflow of the collection system.

(3)  Storage areas that store containers holding only wastes that do not contain free liquids need not have a containment system defined by sub. (2) , except as provided by sub. (4) , provided that either of the following conditions is met:

(a) The storage area is sloped or is otherwise designed and operated to drain and remove liquid resulting from precipitation.

(b) The containers are elevated or are otherwise protected from contact with accumulated liquid.

(4)  Storage areas that store containers holding F020, F021, F022, F023, F026 or F027 wastes that do not contain free liquids shall have a containment system defined by sub. (2) .
