Chapter NR 273

NR 273.031(1)(h) (h) Degreasing spent solvents.

NR 273.031(2) (2) Tube reducing spent lubricants.

NR 273.031(2)(a) (a) Tube reducing spent lubricant process wastewater pollutants may not be discharged, except as provided in par. (b).

NR 273.031(2)(b) (b) Tube reducing spent lubricant process wastewater pollutants may be discharged, with no allowance for any pollutants discharged, if the facility owner or operator demonstrates according to pars. (c), (d), (e), and (f) that the concentrations of nitrosamine compounds in the discharged wastewater do not exceed the following levels: - See PDF for table

NR 273.031(2)(c) (c) For the demonstration required by par. (b), the facility owner or operator shall use the analytical methods approved by ch. NR 219, Table C.

NR 273.031(2)(d) (d) The demonstration required by par. (b) shall be made once per month until the demonstration has been made for all 3 nitrosamine compounds for 6 consecutive months. After this time, the demonstration may be made once per quarter. If a sample is found to contain any of the 3 nitrosamine compounds at concentrations greater than those specified in par. (b), the actions set forth in par. (e) shall be taken and the demonstration required by par. (b) shall be made once per month until it has been made for all 3 nitrosamine compounds for 6 consecutive months.

NR 273.031(2)(e) (e) If sampling results show that any of the 3 nitrosamine compounds is present in the process wastewater at concentrations greater than those set forth in par. (b), the facility owner or operator shall ensure that starting within 30 days of receiving written notification of the sampling results no tube reducing spent lubricant wastewater is discharged until one of the following conditions is met:

NR 273.031(2)(e)1. 1. The owner or operator performs a subsequent analysis which demonstrates that the concentrations of 3 regulated nitrosamine compounds do not exceed the levels set forth in par. (b); or

NR 273.031(2)(e)2. 2. The owner or operator substitutes a new tube reducing lubricant and thereafter complies with the requirements of par. (d); or

NR 273.031(2)(e)3. 3. Determines the source of the pollutants whose concentration exceeded the level set forth in par. (b) and demonstrates to the satisfaction of the permit issuing authority that the source has been eliminated.

NR 273.031(2)(f) (f) The concentration limits specified in par. (b) apply at the point of discharge from the tube reducing process. However, sampling after the tube reducing wastewater has been commingled with other wastewaters is permitted if 2 conditions are met:

NR 273.031(2)(f)1. 1. Any dilution caused by the other wastewaters is accounted for when determining the appropriate allowable discharge concentration; and

NR 273.031(2)(f)2. 2. An analytical method of sufficient sensitivity is used to measure the levels of each of the 3 nitrosamine compounds in the wastewater being sampled.
