Section NR 667.1101 - What design and operating standards shall my containment building meet? Comply with the design and operating standards in this section. The department shall consider standards established by professional organizations generally recognized by the industry such as the American Concrete Institute (ACI) and the American Society of Testing Materials (ASTM) in judging the structural integrity requirements of this section.
(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.(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: (a) Support themselves, the waste contents, and any personnel and heavy equipment that operates within the unit.(b) Prevent failure due to: 1. Pressure gradients, settlement, compression, or uplift.2. Physical contact with the hazardous wastes to which they are exposed.4. Stresses of daily operation, including the movement of heavy equipment within the unit and contact of such equipment with containment walls.5. Collapse or other failure.(3) All surfaces to be in contact with hazardous wastes shall be chemically compatible with those wastes.(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.(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.(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: (a) They provide an effective barrier against fugitive dust emissions under s. NR 667.1102(4).(b) The unit is designed and operated in a fashion that assures that wastes will not actually come in contact with these openings.(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.(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.Wis. Admin. Code Department of Natural Resources NR 667.1101
