NR 665.0221(4)(a)
(a) The monofill contains only hazardous wastes from foundry furnace emission controls or metal casting molding sand, and the wastes do not contain constituents which would render the wastes hazardous for reasons other than the toxicity characteristic in s.
NR 661.0024, with EPA hazardous waste numbers D004 to D017.
NR 665.0221(4)(b)1.a.
a. The monofill has at least one liner for which there is no evidence that the liner is leaking. For the purposes of this subsection the term “liner" means a liner designed, constructed, installed and operated to prevent hazardous waste from passing into the liner at any time during the active life of the facility, or a liner designed, constructed, installed and operated to prevent hazardous waste from migrating beyond the liner to adjacent subsurface soil, groundwater or surface water at any time during the active life of the facility. In the case of any surface impoundment which has been exempted from the requirements of sub.
(1) on the basis of a liner designed, constructed, installed and operated to prevent hazardous waste from passing beyond the liner, at the closure of the impoundment the owner or operator shall remove or decontaminate all waste residues, all contaminated liner material and contaminated soil to the extent practicable. If all contaminated soil is not removed or decontaminated, the owner of operator of the impoundment shall comply with appropriate long-term care requirements, including but not limited to groundwater monitoring and corrective action.

NR 665.0221(4)(b)2.
2. The owner or operator demonstrates that the monofill is located, designed and operated so as to assure that there will be no migration of any hazardous constituent into groundwater or surface water at any future time.
NR 665.0221(5)
(5) In the case of any unit in which the liner and leachate collection system has been installed pursuant to the requirements of sub.
(1) and in good faith compliance with sub.
(1) and with guidance documents governing liners and leachate collection systems under sub.
(1), no liner or leachate collection system which is different from that which was so installed pursuant to sub.
(1) will be required for the unit by the department when issuing the first operating license to the facility, except that the department will not be precluded from requiring installation of a new liner when the department has reason to believe that any liner installed pursuant to the requirements of sub.
(1) is leaking.

The owner or operator of surface impoundment units subject to s.
NR 665.0221 (1) shall submit a proposed action leakage rate to the department when submitting the notice required under s.
NR 665.0221 (2). Within 60 days of receipt of the notification, the department shall establish an action leakage rate, either as proposed by the owner or operator or modified using the criteria in this section, or extend the review period for up to 30 days. If no action is taken by the department before the original 60 or extended 90 day review periods, the action leakage rate shall be approved as proposed by the owner or operator.
NR 665.0222(2)
(2) The department shall approve an action leakage rate for surface impoundment units subject to s.
NR 665.0221 (1). The action leakage rate is the maximum design flow rate that the leak detection system can remove without the fluid head on the bottom liner exceeding one foot. The action leakage rate shall include an adequate safety margin to allow for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness of drainage material), construction, operation and location of the leak detection system, waste and leachate characteristics, likelihood and amounts of other sources of liquids in the leak detection system and proposed response actions (e.g., the action leakage rate shall consider decreases in the flow capacity of the system over time resulting from siltation and clogging, rib layover and creep of synthetic components of the system, overburden pressures, etc.).
NR 665.0222(3)
(3) To determine if the action leakage rate has been exceeded, the owner or operator shall convert the weekly or monthly flow rate from the monitoring data obtained under s.
NR 665.0226 (2), to an average daily flow rate (gallons per acre per day) for each sump. Unless the department approves a different calculation, the average daily flow rate for each sump shall be calculated weekly during the active life and closure period, and if the unit closes in accordance with s.
NR 665.0228 (1) (b), monthly during the long-term care period when monthly monitoring is required under s.
NR 665.0226 (2).
