NR 204 or 214. NR 205.07(3)(b)(b) Spill reporting. The permittee shall notify the department in accordance with ch. NR 158, in the event that a spill or accidental release of any material or substance results in the discharge of pollutants to the waters of the state at a rate or concentration greater than the effluent limitations established in the permit, or the spill or accidental release of the material is unregulated in the permit, unless the spill or release of pollutants has been reported to the department under this section. NR 205.07 NoteNote: Chapter NR 158 has been repealed.
NR 205.07(3)(c)(c) Planned changes. In accordance with ss. 283.31 (4) (b) and 283.59 (1), Stats., the permittee shall report to the department any facility expansion, production increase or process modifications which will result in new, different or increased discharges of pollutants.

The notice shall contain a description of the new activities, an estimate of the new, different or increased discharge of pollutants and a description of the effect of the new or increased discharge on existing waste treatment facilities. Following receipt of this report, the department may modify the permit to specify and limit any pollutants not previously regulated in the permit.
