NR 665.0223 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06. NR 665.0224(1)(1) The owner or operator of surface impoundment units subject to s. NR 665.0221 (1) shall develop and keep on site until closure of the facility a response action plan. 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 665.0224(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 665.0224(2)(a)(a) Notify the department in writing of the exceedence within 7 days of the determination. NR 665.0224(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 665.0224(2)(c)(c) Determine to the extent practicable the location, size and cause of any leak. NR 665.0224(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 665.0224(2)(e)(e) Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks. NR 665.0224(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 665.0224(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 665.0224(3)(a)3.3. Assess the seriousness of any leaks in terms of potential for escaping into the environment. NR 665.0224 HistoryHistory: CR 05-032: cr.

In addition to the waste analyses required by s. NR 665.0013, whenever a surface impoundment is to be used to chemically treat a hazardous waste which is substantially different from waste previously treated in that impoundment or chemically treat hazardous waste with a substantially different process than any previously used in that impoundment, before treating the different waste or using the different process the owner or operator shall do either of the following: NR 665.0225(1)(1) Conduct waste analyses and trial treatment tests (e.g., bench scale or pilot plant scale tests). NR 665.0225(2)(2) Obtain written, documented information on similar treatment of similar waste under similar operating conditions to show that this treatment will comply with s. NR 665.0017 (2). NR 665.0225 NoteNote: As required by s. NR 665.0013, the waste analysis plan shall include analyses needed to comply with ss. NR 665.0229 and 665.0230. As required by s. NR 665.0073, the owner or operator shall place the results from each waste analysis and trial test, or the documented information, in the operating record of the facility.

NR 665.0226(1)(1) The owner or operator shall inspect both of the following: NR 665.0226(1)(b)(b) The surface impoundment, including dikes and vegetation surrounding the dike, at least once a week to detect any leaks, deterioration or failures in the impoundment. NR 665.0226(2)(a)(a) An owner or operator required to have a leak detection system under s. NR 665.0221 (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 665.0226(2)(b)(b) 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.
