NR 211 and achieve the following pretreatment standards for existing sources by July 1, 1984.

(a) There shall be no discharge of polychlorinated biphenyl compounds such as those used for transformer fluid.

(b) The quantity of pollutants in each of the wastewater sources identified in Table 4 may not exceed the concentration listed in that table.

(c) Where the discharger requests and the control authority approves in writing, instead of monitoring cooling tower blowdown, compliance with the limitations for the 126 priority pollutants may be determined by engineering calculations which demonstrate that the regulated pollutants are not present or are present in the final discharge in no detectable amount.

(2)   Pretreatment standards for new sources ( PSNS ). Except as provided in s. NR 211.13 any new source subject to this section which introduces pollutants into a publicly owned treatment works shall comply with ch. NR 211 and the following pretreatment standards for new sources:

(a) There may be no discharge of polychlorinated biphenyl compounds such as those used for transformer fluid.

(b) The quantity of pollutants in each of the wastewater sources identified in Table 4 may not exceed the concentration listed in that table.

(c) Where the discharger requests and the control authority approves in writing, instead of monitoring cooling tower blowdown, compliance with the limitations for the 126 priority pollutants may be determined by engineering calculations which demonstrate that the regulated pollutants are not present or are present in the final discharge in no detectable amount.

(d) There may be no discharge of wastewater pollutants from fly ash transport water. - See PDF for table
