Current through Supplement No. 395, January, 2025

If the containment building will be used to manage hazardous wastes containing free liquids or treated with free liquids, as determined by the paint filter test, by a visual examination, or by other appropriate means, the owner or operator must include:

1. A primary barrier designed and constructed of materials to prevent the migration of hazardous constituents into the barrier (for example, a geomembrane covered by a concrete wear surface).

2. A liquid collection and removal system to minimize the accumulation of liquid on the primary barrier of the containment building.

a. The primary barrier must be sloped to drain liquids to the associated collection system; and

b. Liquids and waste must be removed to minimize hydraulic head on the containment system at the earliest practicable time.

3. A secondary containment system, including a secondary barrier designed and constructed to prevent migration of hazardous constituents into the barrier, and a leak detection system capable of detecting failure of the primary barrier and collecting accumulated hazardous wastes and liquids at the earliest practical time.

a. The requirements of the leak detection component of the secondary containment system may be met by installing a system that is, at a minimum:
(1) Constructed with a bottom slope of one percent or more; and

(2) Constructed of a granular drainage material with a hydraulic conductivity of 1x10-2 centimeters per second or more and a thickness of twelve inches [30.5 centimeters] or more, or constructed of synthetic or geonet drainage materials with a transmissivity of 3x10-5 meters squared per second or more.

b. If treatment will be conducted in the building, the area in which the treatment will be conducted must be designed to prevent the release of liquids, wet materials, or liquid aerosols to other portions of the building.

c. The secondary containment system must be constructed using materials that are chemically resistant to the waste and liquids managed in the containment building and of sufficient strength and thickness to prevent collapse under the pressure exerted by overlaying materials and by any equipment used in the containment building.
