NR 667.1101(1) (1)The containment building shall be completely enclosed with a floor, walls, and a roof to prevent exposure to the elements, (for example, precipitation, wind, run-on), and to assure containment of managed wastes.
NR 667.1101(2) (2)The floor and containment walls of the unit, including the secondary containment system, if required under s. NR 667.1103, shall be designed and constructed of manmade materials of sufficient strength and thickness to:
NR 667.1101(2)(a) (a) Support themselves, the waste contents, and any personnel and heavy equipment that operates within the unit.
NR 667.1101(2)(b) (b) Prevent failure due to:
NR 667.1101(2)(b)1. 1. Pressure gradients, settlement, compression, or uplift.
NR 667.1101(2)(b)2. 2. Physical contact with the hazardous wastes to which they are exposed.
NR 667.1101(2)(b)3. 3. Climatic conditions.
NR 667.1101(2)(b)4. 4. Stresses of daily operation, including the movement of heavy equipment within the unit and contact of such equipment with containment walls.
NR 667.1101(2)(b)5. 5. Collapse or other failure.
NR 667.1101(3) (3)All surfaces to be in contact with hazardous wastes shall be chemically compatible with those wastes.
NR 667.1101(4) (4)You may not place incompatible hazardous wastes or treatment reagents in the unit or its secondary containment system if they could cause the unit or secondary containment system to leak, corrode, or otherwise fail.
NR 667.1101(5) (5)A containment building shall have a primary barrier designed to withstand the movement of personnel, waste, and handling equipment in the unit during the operating life of the unit and appropriate for the physical and chemical characteristics of the waste to be managed.
NR 667.1101(6) (6)If appropriate to the nature of the waste management operation to take place in the unit, an exception to the structural strength requirement may be made for light-weight doors and windows that meet these criteria:
NR 667.1101(6)(a) (a) They provide an effective barrier against fugitive dust emissions under s. NR 667.1102 (4).
NR 667.1101(6)(b) (b) The unit is designed and operated in a fashion that assures that wastes will not actually come in contact with these openings.
NR 667.1101(7) (7)Inspect and record in the facility's operating record, at least once every 7 days, data gathered from monitoring equipment and leak detection equipment, as well as the containment building and the area immediately surrounding the containment building to detect signs of releases of hazardous waste.
NR 667.1101(8) (8)Obtain certification by a qualified professional engineer that the containment building design meets the requirements of subs. (1) to (6) and ss. NR 667.1102 and 667.1103.

NR 667.1102 NR 667.1102What other requirements shall I meet to prevent releases? Use controls and practices to ensure containment of the hazardous waste within the unit, and at a minimum:
NR 667.1102(1) (1)Maintain the primary barrier to be free of significant cracks, gaps, corrosion, or other deterioration that could cause hazardous waste to be released from the primary barrier.
NR 667.1102(2) (2)Maintain the level of the stored or treated hazardous waste within the containment walls of the unit so that the height of any containment wall is not exceeded.
NR 667.1102(3) (3)Take measures to prevent personnel or by equipment used in handling the waste from tracking hazardous waste out of the unit. Designate an area to decontaminate equipment and collect and properly manage any rinsate.
NR 667.1102(4) (4)Take measures to control fugitive dust emissions such that any openings (such as doors, windows, vents, and cracks) exhibit no visible emissions (see 40 CFR part 60, Appendix A, Method 22—Visual Determination of Fugitive Emissions from Material Sources and Smoke Emissions from Flares). In addition, operate and maintain all associated particulate collection devices (for example, fabric filter, electrostatic precipitator) with sound air pollution control practices. Effectively maintain this state of no visible emissions at all times during routine operating and maintenance conditions, including when vehicles and personnel are entering and exiting the unit.

NR 667.1103(2) (2)A liquid collection and removal system to minimize the accumulation of liquid on the primary barrier of the containment building.
NR 667.1103(2)(a) (a) The primary barrier shall be sloped to drain liquids to the associated collection system.
NR 667.1103(2)(b) (b) Collect and remove liquids and waste to minimize hydraulic head on the containment system at the earliest practicable time.
NR 667.1103(3) (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.
NR 667.1103(3)(a) (a) You may meet the requirements of the leak detection component of the secondary containment system by installing a system that is, at a minimum:
NR 667.1103(3)(a)1. 1. Constructed with a bottom slope of one percent or more.
NR 667.1103(3)(a)2. 2. Constructed of a granular drainage material with a hydraulic conductivity of 1 × 10-2 cm/sec or more and a thickness of 12 inches (30.5 cm) or more, or constructed of synthetic or geonet drainage materials with a transmissivity of 3 × 10–5 m2sec or more.
NR 667.1103(3)(b) (b) If you will be conducting treatment in the building, design the area in which the treatment will be conducted to prevent the release of liquids, wet materials or liquid aerosols to other portions of the building.
NR 667.1103(3)(c) (c) Construct the secondary containment system 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.
