NR 205.07(1)(q)3.
3. The alteration or addition results in a significant change in the permittee's sludge use or disposal practices, and such alteration, addition, or change may justify the application of permit conditions that are different from or absent in the existing permit, including notification of additional use or disposal sites not reported during the permit application process nor reported pursuant to an approved land application plan. Additional sites may not be used for the land application of sludge until department approval is received, as required by

NR 205.07(1)(u)
(u)
Bypassing. Except for a controlled diversion as provided in
par. (v), any bypass is prohibited. The Department may approve the following:
NR 205.07(1)(u)1.
1. `Blending.' The bypass event is blending at a sewage treatment facility and complies with the requirements of
s. NR 210.12.
NR 205.07(1)(u)2.
2. `Scheduled bypass.' The bypass event is scheduled or anticipated in advance by the permittee and the permittee received prior written approval from the department for the scheduled bypass. A permittee's written request for department approval of a scheduled bypass shall demonstrate that the conditions in
subd. 3. are met and include the proposed date and reason for the bypass, estimated volume and duration of the bypass, alternatives to bypassing, and measures to mitigate environmental harm caused by the bypass. The department may require the permittee to provide public notification for a scheduled bypass if it is determined there is significant public interest in the proposed action.
NR 205.07 Note
Note: If the department determines there is significant public interest in the proposed action, the department may schedule a public hearing or notice regarding the proposal for a scheduled bypass.
NR 205.07(1)(u)3.
3. `Other bypass.' The permittee demonstrates that all of the following apply:
NR 205.07(1)(u)3.a.
a. The bypass was unavoidable to prevent loss of life, personal injury, or severe property damage.
NR 205.07(1)(u)3.b.
b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities or adequate back-up equipment, retention of untreated wastes, reduction of inflow and infiltration, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventative maintenance.
NR 205.07 Note
Note: When evaluating feasibility of alternatives, the department may consider factors such as technical achievability, costs and affordability of implementation and risks to public health, the environment, and, where the permittee is a municipality, the welfare of the community served.
NR 205.07 Note
Note: Pursuant to ss.
283.89 and
283.91, Stats., violations of permit conditions or rule requirements are referred to the department of justice for enforcement.

1. Effluent from the sewage treatment facility or wastewater treatment facility shall meet the effluent limitations established in the permit. Wastewater that is diverted around a treatment unit or treatment process during a controlled diversion shall be recombined with wastewater that is not diverted prior to the effluent sampling location and prior to effluent discharge.
NR 205.07(1)(v)2.
2. A controlled diversion may not occur during periods of excessive flow or other abnormal wastewater characteristics.
NR 205.07(1)(v)3.
3. A controlled diversion may occur only when necessary for essential maintenance to assure efficient operation.

Note: Sewage treatment facilities that have multiple treatment units to treat variable or seasonal loading conditions may shut down redundant treatment units when necessary for efficient operation.
NR 205.07(1)(v)4.
4. A controlled diversion may not result in a sewage treatment facility or wastewater treatment facility overflow.
NR 205.07(1)(v)5.
5. All instances of controlled diversions shall be documented in sewage treatment facility or wastewater treatment facility records and such records shall be available to the department on request.
NR 205.07(1)(x)

Permit as enforcement shield. Compliance with a permit during its term constitutes compliance for purposes of enforcement with
33 USC 1311,
1312,
1316,
1317,
1328, and
1345 (a) and (b), except for any toxic effluent standard or prohibition, and standards for sewage sludge use or disposal. If a new or revised toxic effluent standard or toxic prohibition becomes effective during the term of the permit, the permittee may be subject to enforcement action if the discharge exceeds the new or revised effluent standard for the toxic pollutant even though the discharge is in compliance with the existing permit. The permittee may also be subject to enforcement action standards for sewage sludge use or disposal. However, a permit may be modified, revoked and reissued, or terminated during its term for cause as set forth in
ch. 283, Stats., and
ch. NR 203.
NR 205.07 Note
Note: The toxic effluent standards in s.
NR 205.07 (1) (x) are the technology based limitations applicable to the categorical sources in accordance with

Solids, sludges, filter backwash or other pollutants removed from or resulting from treatment or control of wastewaters or intake waters shall be stored and disposed of in a manner to prevent any pollutant from the materials from entering the waters of the state. Land disposal or application of treatment plant solids and sludges shall be at a site or operation licensed by the department under
chs. NR 500 to
