NR 665.0303(2)(d)(d) Determine whether waste receipt should cease or be curtailed, whether any waste should be removed from the unit for inspection, repairs or controls and whether or not the unit should be closed.
NR 665.0303(2)(e)(e) Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks.
NR 665.0303(2)(f)(f) Within 30 days after the notification that the action leakage rate has been exceeded, submit to the department the results of the analyses specified in pars. (c), (d) and (e), the results of actions taken and actions planned. Monthly thereafter, as long as the flow rate in the leak detection system exceeds the action leakage rate, the owner or operator shall submit to the department a report summarizing the results of any remedial actions taken and actions planned.
NR 665.0303(3)(3)To make the leak and remediation determinations in sub. (2) (c), (d) and (e), the owner or operator shall comply with par. (a) or (b):
NR 665.0303(3)(a)(a) Do all of the following:
NR 665.0303(3)(a)1.1. Assess the source of liquids and amounts of liquids by source.
NR 665.0303(3)(a)2.2. Conduct a fingerprint, hazardous constituent or other analyses of the liquids in the leak detection system to identify the source of liquids and possible location of any leaks, and the hazard and mobility of the liquid.
NR 665.0303(3)(a)3.3. Assess the seriousness of any leaks in terms of potential for escaping into the environment.
NR 665.0303(3)(b)(b) Document why the assessments are not needed.

NR 665.0304NR 665.0304Monitoring and inspection.
NR 665.0304(1)(1)An owner or operator required to have a leak detection system under s. NR 665.0301 (1) shall record the amount of liquids removed from each leak detection system sump at least once each week during the active life and closure period.
NR 665.0304(2)(2)After the final cover is installed, the amount of liquids removed from each leak detection system sump shall be recorded at least monthly. If the liquid level in the sump stays below the pump operating level for 2 consecutive months, the amount of liquids in the sumps shall be recorded at least quarterly. If the liquid level in the sump stays below the pump operating level for 2 consecutive quarters, the amount of liquids in the sumps shall be recorded at least semi-annually. If at any time during the long-term care period the pump operating level is exceeded at units on quarterly or semi-annual recording schedules, the owner or operator shall return to monthly recording of amounts of liquids removed from each sump until the liquid level again stays below the pump operating level for 2 consecutive months.
NR 665.0304(3)(3)“Pump operating level” is a liquid level proposed by the owner or operator and approved by the department based on pump activation level, sump dimensions and level that avoids backup into the drainage layer and minimizes head in the sump. The timing for submission and approval of the proposed “pump operating level” will be in accordance with s. NR 665.0302 (1).

NR 665.0309NR 665.0309Surveying and recordkeeping. The owner or operator of a landfill shall maintain both of the following items in the operating record required in s. NR 665.0073:
NR 665.0309(1)(1)On a map, the exact location and dimensions, including depth, of each cell with respect to permanently surveyed benchmarks.
NR 665.0309(2)(2)The contents of each cell and the approximate location of each hazardous waste type within each cell.

NR 665.0310NR 665.0310Closure and long-term care.
NR 665.0310(1)(1)At final closure of the landfill or upon closure of any cell, the owner or operator shall cover the landfill or cell with a final cover designed and constructed to do all of the following:
NR 665.0310(1)(a)(a) Provide long-term minimization of migration of liquids through the closed landfill.
NR 665.0310(1)(b)(b) Function with minimum maintenance.
NR 665.0310(1)(c)(c) Promote drainage and minimize erosion or abrasion of the cover.
NR 665.0310(1)(d)(d) Accommodate settling and subsidence so that the cover’s integrity is maintained.
NR 665.0310(1)(e)(e) Have a permeability less than or equal to the permeability of any bottom liner system or natural subsoils present.
NR 665.0310(2)(2)After final closure, the owner or operator shall comply with all long-term care requirements contained in ss. NR 665.0117 to 665.0120, including maintenance and monitoring throughout the long-term care period. The owner or operator shall do all of the following:
NR 665.0310(2)(a)(a) Maintain the integrity and effectiveness of the final cover, including making repairs to the cover as necessary to correct the effects of settling, subsidence, erosion or other events.
NR 665.0310(2)(b)(b) Maintain and monitor the leak detection system in accordance with ss. NR 664.0301 (3) (c) 4. and (d) and 665.0304 (2), and comply with all other applicable leak detection system requirements of this chapter.
