NR 200.22(1)(e)6.a.
a. Sample results fall above the limit of quantitation for the analytical method used or that the most sensitive approved analytical method listed for the pollutant in ch.

NR 200.22(1)(f)
(f) Changes which could be made to enhance treatment or source reduction of flows coming to the treatment facility or which would reduce the level of toxicity or the discharge of the pollutant for which the permittee is seeking a variance. This information shall include the following:
NR 200.22(1)(f)1.
1. An estimate of capital and operating costs for the changes and a reasonable schedule for planning and accomplishing the work.
NR 200.22(1)(f)2.
2. If the source of the pollutant is believed to be from dissolution of metals from water supply distribution piping materials:
NR 200.22(1)(f)2.a.
a. Information on past and current water supply treatment practices which may increase or decrease the corrosive nature of the water supply including what changes have been made and when.
NR 200.22(1)(f)2.b.
b. Data on the water supply stability or corrosivity, using one of various methods of determination, for the raw and treated water supply.
NR 200.22(1)(f)2.c.
c. Other potential water sources or methods of water supply treatment as an alternative.
NR 200.22(1)(g)
(g) Information which establishes the significance of industrial and commercial wastewater sources versus domestic wastewater sources of the pollutant for which a variance is requested. This may include an approximate mass-balance calculation of treatment system loadings from all sources.
NR 200.22(1)(h)
(h) For facilities which monitor the treatment system sludge pursuant to requirements in ch.
NR 204 or
214 for the pollutant for which a variance is requested, results of the most recent 3 years of sludge testing, along with volumes disposed of so as to perform an approximate mass balance of the pollutant entering and leaving the plant.
NR 200.22(1)(i)
(i) If a variance is being requested for whole effluent toxicity in conjunction with a specific chemical pollutant or if whole effluent toxicity failures have been experienced and they are believed to have resulted from the pollutant for which the variance is being requested, evidence which points to the pollutant as the cause of the whole effluent toxicity failures.
NR 200.22(1)(j)
(j) Effluent limitations which the permittee believes it can currently achieve.
NR 200.22(1)(k)
(k) Effluent limitations which the permittee believes it can achieve at some later date during the term of the variance and the corresponding schedule which would be followed to meet these limitations.
NR 200.22(1)(L)
(L) Whether the permittee believes it can meet the effluent limitations that give rise to the variance request at any time during the term of the permit.
NR 200.22(1)(m)
(m) A detailed discussion of evidence and reasons why the permittee believes a variance is warranted based on one or more of the grounds listed in s.
NR 200.20 (2).
NR 200.22(1)(n)
(n) Demonstration that the variance requested conforms with antidegradation requirements specified in ch.
NR 207.
NR 200.22(1)(o)
(o) Characterization of the extent of any increased risk to human health and the environment associated with granting the variance so as to allow the department to decide if such increased risk is consistent with protection of the public health, safety and welfare.
NR 200.22(1)(p)
(p) For variance requests based on s.
NR 200.20 (2) (f), the permittee shall conduct a financial impact analysis which shall include an estimate of the capital, operation and maintenance and financing costs, translated into an annualized cost, of potential changes identified in par.
(g) compared with an analysis of financial affordability. The analysis of financial affordability shall include:
NR 200.22(1)(p)1.
1. For publicly owned systems, an estimate of how much annual municipal revenue would need to increase, taking into account any offsetting state shared revenues if the most cost-effective pollutant control option was implemented and how this would affect user fees if user fees were used to finance the costs. This analysis shall also compare projected user fees with user fees in similar communities. If industrial or commercial contributions comprise a significant source of the pollutant, information requested in subd.
2. shall also be provided.
NR 200.22(1)(p)2.
2. For privately owned systems or if the most cost-effective pollutant control option for a publicly owned system involves additional regulation of privately owned contributors as the impacted parties, an estimate of how implementing the most cost-effective pollutant control option would affect profitability and other financial health indicators of the private entity.
NR 200.22(1)(p)3.
3. An analysis of the socioeconomic impacts to the community where the entity is located.
