Immediately remove the portion of the drip pad affected by the condition from service. NR 665.0443(13)(a)3.3. Determine what steps must be taken to repair the drip pad and remove any leakage from below the drip pad, and establish a schedule for accomplishing the clean up and repairs. NR 665.0443(13)(a)4.4. Immediately after discovery of the condition, notify the department of the condition and, within 10 working days, provide a written notice to the department with a description of the steps that will be taken to repair the drip pad and clean up any leakage, and the schedule for accomplishing this work. NR 665.0443(13)(b)(b) The department will review the information submitted, make a determination regarding whether the pad must be removed from service completely or partially until repairs and clean up are complete, and notify the owner or operator of the determination and the underlying rationale in writing. NR 665.0443(13)(c)(c) Upon completing all repairs and clean up, the owner or operator shall notify the department in writing and provide a certification, signed by an independent qualified, registered professional engineer, that the repairs and clean up have been completed according to the written plan submitted in accordance with par.

NR 665.0444(1)(1) During construction or installation, liners, and cover systems (for example, membranes, sheets, or coatings) shall be inspected for uniformity, damage, and imperfections (for example, holes, cracks, thin spots, or foreign materials). Immediately after construction or installation, liners shall be inspected and certified as meeting the requirements of s. NR 665.0443 by a qualified professional engineer. The certification shall be maintained at the facility as part of the facility operating record. After installation, liners, and covers shall be inspected to ensure tight seams and joints and the absence of tears, punctures, or blisters. NR 665.0444(2)(2) While a drip pad is in operation, it shall be inspected weekly and after storms to detect evidence of any of the following: NR 665.0444(2)(a)(a) Deterioration, malfunctions or improper operation of run-on and run-off control systems. NR 665.0444(2)(b)(b) The presence of leakage in and proper functioning of the leakage detection system. NR 665.0444 NoteNote: See s. NR 665.0443(13) for remedial action required if deterioration or leakage is detected. NR 665.0444 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; CR 16-007: am.

NR 665.0445(1)(1) At closure, the owner or operator shall remove or decontaminate all waste residues, contaminated containment system components (such as pads and liners), contaminated subsoils, and structures and equipment contaminated with waste and leakage, and manage them as hazardous waste. NR 665.0445(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 practically removed or decontaminated, the owner or operator shall close the facility and perform long-term care in accordance with closure and long-term care requirements that apply to landfills (s. NR 665.0310). For licensed units, the requirement to have a license continues throughout the long-term care period. NR 665.0445(3)(a)1.1. Include in the closure plan for the drip pad under s. NR 665.0112 both a plan for complying with sub. (1) and a contingent plan for complying with sub. (2) in case not all contaminated subsoils can be practicably removed at closure. NR 665.0445(3)(a)2.2. Prepare a contingent long-term care plan under s. NR 665.0118 for complying with sub. (2) in case not all contaminated subsoils can be practicably removed at closure.
