NR 212.06
NR 212.06 Determination of the total maximum load. NR 212.06(1)(1) When required by
s. NR 212.05, total maximum loads for stream segments shall be established based upon relevant water quality and quantity considerations including, but not limited to, streamflow, water temperature, pH, dissolved oxygen, suspended solids and hardness or other natural background conditions. The stream conditions to be used for calculating the total maximum load are specified in
s. NR 102.03 (3). Variable loadings may be established for a given stream segment to reflect the varying capacity of a stream to assimilate wastes under differing conditions when necessary supporting data is available.
NR 212.06(2)
(2) Total maximum loads established in
ss. NR 212.40 to
212.70 shall be reviewed at least once every 5 years and if necessary, recalculated by the department prior to permit reissuance, based on factors which shall include but not be limited to changes in stream conditions and advancements in stream modeling techniques, discharge characteristics, readjustment of modeling coefficients, utilization of new data, or baseline load revisions under

NR 212.065 Modification of baseline loads. NR 212.065(1)(1) Baseline loads established in
ss. NR 212.40 to
212.70 shall be reviewed at least once every 5 years and if necessary, revised by the department based on factors that shall include, but not be limited to population projections, modifications to categorical effluent limits, production curtailment or expansions, permit expiration and revocation, cessation of discharge or other issues. Any temporary reallocation under
s. NR 212.11 (2) shall be considered as part of baseline load revisions at the 5 year update.
NR 212.065(2)
(2) In proposing revisions to total maximum daily loads or baseline loads in
ss. NR 212.40 to
212.70 due to reallocation, the department staff shall consider increases in allocations only for circumstances when:
NR 212.065(2)(a)
(a) A new discharger requires a wasteload allocation due to insufficient reserve capacity being available in the applicable stream segment; or
NR 212.065(2)(b)
(b) An existing discharger demonstrates to the satisfaction of the department that additional wasteload allocation is required due to a production expansion or municipal growth. The demonstration shall include an analysis of the discharger's current wastewater treatment facility's capability to adequately treat the increased influent. The demonstration shall also include an analysis that the discharger's wastewater treatment facility is adequately maintained and operated at optimal efficiency; or
NR 212.065(2)(c)
(c) An existing discharger demonstrates to the satisfaction of the department that additional wasteload allocation is required due to the inability of its wastewater treatment facility to attain existing wasteload allocations. The demonstration shall include an analysis that the discharger has installed appropriate treatment technology and that the current facility is maintained and operated at optimal efficiency.
NR 212.065(2)(d)
(d) A reallocation of total maximum daily loads would result in establishment of a reserve capacity through procedures identified in
ss. NR 212.40 through
212.70.
NR 212.065(2)(e)
(e) Through use of a toxicity test approved by the department, the discharger applying for an increased total maximum daily load demonstrates that such increase will not result in a failure, as defined by the department, of the toxicity test.

NR 212.09 Note
Note:
For those stream conditions where the allocation of water quality related effluent limitations is necessary, nonpoint source effects on stream segments will normally be accounted for in the water quality model or other technical analysis used to determine the total maximum load. In unforeseen circumstances requiring the specific allocation of a portion of the total maximum load for contributions from nonpoint sources, s.
NR 212.09 can be used. Direct control of contributions from nonpoint sources will be implemented through land management control practices and will not normally be included in a waste load allocation.

NR 212.10
NR 212.10 Point source allocations. NR 212.10(1)
(1) The water quality related effluent limitations for a point source discharge to a stream segment which is not impacted by any other point source shall be calculated by subtracting any allocations for reserve capacity, margin of safety or nonpoint sources from the total maximum loading.
NR 212.10(2)
(2) The procedures for determining water quality related effluent limitations for point source dischargers to a stream segment affected by more than one discharger are found in
ss. NR 212.40 to

NR 212.10(3)
(3) The department may permit point source water quality related effluent limitations to vary according to flow, temperature or other water quality conditions only when all of the following are met:
NR 212.10(3)(a)
(a) The limitations shall result in the attainment of water quality standards; and
NR 212.10(3)(b)
(b) During the term of the permit the discharger provides sufficient monitoring capability where such capability does not otherwise exist.
NR 212.10(4)
(4) Water quality related effluent limits shall be expressed as daily maximum loads. Consistent with techniques established under
ss. NR 212.40 through
212.70 effluent limits may be expressed as averages in conjunction with daily maximum limits if the permittee demonstrates that such limits would not increase the probability of water quality standards violations. The flow and temperature measurements of stream conditions for flow and temperature related permits may be based on averages in cases where averages better approximate actual river conditions.
