subch. DD of ch. NR 667 Subchapter DD — Containment Buildings

NR 667.1100 NR 667.1100 Does this subchapter apply to me? This subchapter applies to you if you own or operate a facility that treats or stores hazardous waste in containment buildings under a subch. J of ch. NR 667 standardized license, except as provided in s. NR 667.0001 (2). Storage or treatment in your containment building is not land disposal as defined in s. NR 668.02 if your unit meets the requirements of ss. NR 667.1101, 667.1102, and 667.1103.

NR 667.1101 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.

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.
