NR 664.1101(3)(3)Owners or operators of all containment buildings shall do all of the following:
NR 664.1101(3)(a)(a) Use controls and practices to ensure containment of the hazardous waste within the unit; and, at a minimum, do all of the following:
NR 664.1101(3)(a)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 664.1101(3)(a)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 664.1101(3)(a)3.3. Take measures to prevent the tracking of hazardous waste out of the unit by personnel or by equipment used in handling the waste. An area shall be designated to decontaminate equipment and any rinsate shall be collected and properly managed.
NR 664.1101(3)(a)4.4. Take measures to control fugitive dust emissions such that any openings (doors, windows, vents, cracks, etc.) 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, incorporated by reference in s. NR 660.11). In addition, all associated particulate collection devices (e.g., fabric filter, electrostatic precipitator) shall be operated and maintained with sound air pollution control practices (see s. NR 439.055 for guidance). This state of no visible emissions shall be maintained effectively at all times during routine operating and maintenance conditions, including when vehicles and personnel are entering and exiting the unit.
NR 664.1101(3)(b)(b) Obtain certification by a qualified professional engineer that the containment building design meets the requirements of subs. (1) and (2) and this subsection.
NR 664.1101(3)(c)(c) Throughout the active life of the containment building, if the owner or operator detects a condition that could lead to or has caused a release of hazardous waste, repair the condition promptly, in accordance with all of the following procedures:
NR 664.1101(3)(c)1.1. Upon detection of a condition that has led to a release of hazardous waste (e.g., upon detection of leakage from the primary barrier), the owner or operator shall do all of the following:
NR 664.1101(3)(c)1.a.a. Enter a record of the discovery in the facility operating record.
NR 664.1101(3)(c)1.b.b. Immediately remove the portion of the containment building affected by the condition from service.
NR 664.1101(3)(c)1.c.c. Determine what steps must be taken to repair the containment building, remove any leakage from the secondary collection system and establish a schedule for accomplishing the cleanup and repairs.
NR 664.1101(3)(c)1.d.d. Within 7 days after the discovery of the condition, notify the department of the condition, and within 14 working days provide a written notice to the department with a description of the steps taken to repair the containment building and the schedule for accomplishing the work.
NR 664.1101(3)(c)2.2. The department will review the information submitted, make a determination regarding whether the containment building must be removed from service completely or partially until repairs and cleanup are complete and notify the owner or operator of the determination and the underlying rationale in writing.
NR 664.1101(3)(c)3.3. Upon completing all repairs and cleanup the owner or operator shall notify the department in writing and provide a verification, signed by a qualified, registered professional engineer, that the repairs and cleanup have been completed according to the written plan submitted in accordance with subd. 1. d.
NR 664.1101(3)(d)(d) Inspect and record in the facility 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 664.1101(4)(4)For containment buildings that contain areas both with and without secondary containment, the owner or operator shall do all of the following:
NR 664.1101(4)(a)(a) Design and operate each area according to the requirements in subs. (1) to (3).
NR 664.1101(4)(b)(b) Take measures to prevent the release of liquids or wet materials into areas without secondary containment.
NR 664.1101(4)(c)(c) Maintain in the facility’s operating log a written description of the operating procedures used to maintain the integrity of areas without secondary containment.
NR 664.1101(5)(5)Notwithstanding any other provision of this subchapter the department may waive requirements for secondary containment for a licensed containment building where the owner or operator demonstrates that the only free liquids in the unit are limited amounts of dust suppression liquids required to meet occupational health and safety requirements, and where containment of managed wastes and liquids can be assured without a secondary containment system.

NR 664.1102NR 664.1102Closure and long-term care.
NR 664.1102(1)(1)At closure of a containment building, the owner or operator shall remove or decontaminate all waste residues, contaminated containment system components (liners, etc.,) contaminated subsoils and structures and equipment contaminated with waste and leachate, and manage them as hazardous waste unless s. NR 661.0003 (4) applies. The closure plan, closure activities, cost estimates for closure and financial responsibility for containment buildings shall meet all of the requirements specified in subchs. G and H.
NR 664.1102(2)(2)If, after removing or decontaminating all residues and making all reasonable efforts to effect removal or decontamination of contaminated components, subsoils, structures and equipment as required in sub. (1), the owner or operator finds that not all contaminated subsoils can be practicably removed or decontaminated, the owner or operator shall close the facility and perform long-term care in accordance with the closure and long-term care requirements that apply to landfills (s. NR 664.0310). In addition, for the purposes of closure, long-term care and financial responsibility, the containment building is then considered to be a landfill, and the owner or operator shall meet all of the requirements for landfills specified in subchs. G and H.
