NR 665.0302 NR 665.0302 Action leakage rate.
NR 665.0302(1)(1)The owner or operator of landfill units subject to s. NR 665.0301 (1) shall submit a proposed action leakage rate to the department when submitting the notice required under s. NR 665.0301 (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 665.0302(2) (2)The department shall approve an action leakage rate for landfill units subject to s. NR 665.0301 (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 665.0302(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 665.0304, 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 monthly during the long-term care period when monthly monitoring is required under s. NR 665.0304 (2).

The response action plan shall set forth the actions to be taken if the action leakage rate has been exceeded. At a minimum, the response action plan shall describe the actions specified in sub. (2).
NR 665.0303(2) (2)If the flow rate into the leak detection system exceeds the action leakage rate for any sump, the owner or operator shall do all of the following:
NR 665.0303(2)(a) (a) Notify the department in writing of the exceedence within 7 days of the determination.
NR 665.0303(2)(b) (b) Submit a preliminary written assessment to the department within 14 days of the determination, as to the amount of liquids, likely sources of liquids, possible location, size and cause of any leaks and short-term actions taken and planned.
NR 665.0303(2)(c) (c) Determine to the extent practicable the location, size and cause of any leak.
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 665.0304(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).
