NR 260.22(1)(1)
Any existing source which introduces pollutants into a publicly owned treatment works shall comply with ch.
NR 211 and achieve the following pretreatment standards for existing sources (PSES). The subcategories referred to in Tables 1 through 4 are those process subcategories listed in s.
NR 260.02 (1).
NR 260.22(1)(a)
(a) No industrial user introducing wastewater pollutants into a publicly owned treatment works under the provisions of this chapter may augment the use of process wastewater or otherwise dilute the wastewater as a partial or total substitute for adequate treatment to achieve compliance with this standard.
NR 260.22(1)(b)
(b) For facilities discharging less than 38,000 liters (10,000 gal.) per calendar day of electroplating process wastewater the following limitations shall apply:

(e) In the absence of strong chelating agents, after reduction of hexavalent chromium wastes, and after neutralization using calcium oxide (or hydroxide), the following control program may be elected by the industrial user, with the approval of the control authority, in place of the limitations in Table 2. These optional pollutant limitations are not eligible for allowance for removal achieved by the publicly owned treatment works.

NR 260.23 Total toxic organics monitoring requirements. NR 260.23(1)(1)
In place of monitoring for TTO, the control authority may allow industrial users of publicly owned treatment works to make the following certification to replace the periodic reports required by s.
NR 211.15:
“Based on my inquiry of the person or persons directly responsible for managing compliance with the pretreatment standard for total toxic organics (TTO), I certify that, to the best of my knowledge and belief, no dumping of concentrated toxic organics into the wastewaters has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the toxic organic plan submitted to the control authority."
NR 260.23(2)
(2) Industrial users of publicly owned treatment works shall submit a toxic organic management plan when requesting that monitoring not be required. The plan shall specify the toxic organic compounds used; the method of disposal used instead of dumping, such as reclamation, contract hauling, or incineration; and procedures for assuring that toxic organics do not routinely spill or leak into the wastewater.
NR 260.23(3)
(3) An existing source submitting a certification in lieu of monitoring pursuant to subs.
(1) and
(2) shall implement the toxic organic management plan approved by the control authority.
NR 260.23(4)
(4) If monitoring is necessary to measure compliance with the TTO standard, the industrial user need analyze only for those pollutants reasonably expected to be present.
