Chapter NR 212

NR 212.11(1) (1) When a discharger to a publicly-owned point source covered by this chapter applies to receive a separate WPDES permit or when a person with a WPDES permit applies to terminate its direct discharge in order to contribute to a publicly-owned point source covered by this chapter, permit modification procedures contained in ss. 283.37 and 283.53 (2), Stats., shall apply. Any reallocation pursuant to such action shall only affect the applicant and the publicly-owned point source to which it discharges.

NR 212.11(2) (2) Procedures for temporary reallocation for individual stream segments are identified in ss. NR 212.40 through 212.70. Notwithstanding procedures identified in ss. NR 212.40 through 212.70, temporary reallocation of wasteload allocations may be allowed under the following conditions:

NR 212.11(2)(a) (a) Reallocations approved by the department shall be for at least one calendar year and shall expire at the end of the affected discharger’s WPDES permit term;

NR 212.11(2)(b) (b) Reallocations shall account for differences in waste characteristics and location of discharge as determined by the department and may not adversely affect a downstream segment’s wasteload allocation; and

NR 212.11(2)(c) (c) Reallocations may not affect baseline loads in affected stream segments but may result in an adjustment to total maximum daily loads identified in ss. NR 212.40 through 212.70.

NR 212.11(3) (3) Reallocations may not be approved by the department until the discharger applying for a reallocation demonstrates through the use of a toxicity test approved by the department that such reallocation will not result in toxicity in the receiving water.

NR 212.11(4) (4) Prior to department approval of a reallocation, all parties to the transfer shall waive all rights under s. 227.51, Stats., to retain any reallocation beyond the expiration date of the WPDES permit of the dischargers applying to receive a reallocation. The waiver shall be effectuated through incorporation into the WPDES permit of the affected discharger.

NR 212.115 NR 212.115 Transferable wasteload allocation.

NR 212.115(1) (1) Transfers of wasteload allocations between point source dischargers may be allowed through the permit issuance or modification process under the following conditions:

NR 212.115(1)(a) (a) The discharger applying to receive a transfer secures a legally binding agreement approved by the department, that the WPDES permit allocations for one or more existing dischargers shall be reduced by an amount sufficient to prevent the total maximum load under ss. NR 212.40 to 212.70 from being exceeded;

NR 212.115(1)(b) (b) The department shall consider the differences in waste characteristics and location of the affected point sources to determine amounts by which the existing point source allocations are reduced; and

NR 212.115(1)(c) (c) Transfer agreements approved by the department shall be for at least one wasteload allocation season and may not extend beyond the term of the seller’s discharge permit.

NR 212.115(1)(d) (d) Transfers may not be approved by the department until the discharger applying for an increased wasteload allocation demonstrates through the use of a toxicity test approved by the department that the transfer will not result in a failure, as defined by the department, of the toxicity test.

NR 212.115(2) (2) Prior to department approval of a transfer, the discharger applying for an increased wasteload allocation shall demonstrate to the satisfaction of the department that the increase is needed due to:

NR 212.115(2)(a) (a) New production by a new discharger,

NR 212.115(2)(b) (b) Increased production which cannot be accommodated by the current treatment facility, or

NR 212.115(2)(c) (c) The inability of the current waste treatment facility to meet current wasteload allocations despite optimal operation and maintenance of the treatment facility.

NR 212.115(3) (3) Prior to department approval of a transfer, all parties to the transfer shall waive all rights under s. 227.51, Stats., to retain any transfer beyond the expiration date of the WPDES permit of the dischargers applying to receive a transfer. The waiver shall be incorporated into both the legally binding agreement in sub. (1) (a) and the WPDES permit of all parties to the agreement.

NR 212.12(1)(a) (a) A cost-effectiveness analysis is submitted to the department which demonstrates that instream aeration is a satisfactory means of attaining water quality standards; and

NR 212.12(1)(b) (b) A demonstration is made to the satisfaction of the department that applicable water quality standards will be met and no environmental pollution as defined in s. 299.01 (4), Stats., will occur.

NR 212.12(2) (2) Instream aeration may not be used to accommodate new or increased discharges of pollutants either from new point sources or from the expansion of existing point sources, except that instream aeration may be available on a temporary basis to accommodate increased pollution loads due to the growth of a municipality when:

NR 212.12(2)(a) (a) The use of aeration for this purpose is restricted to residential or public sector growth;

NR 212.12(2)(b) (b) Adequate operation and maintenance of the publicly-owned point source exists;

NR 212.12(2)(c) (c) Excessive infiltration and inflow have been removed from the collection systems;

NR 212.12(2)(d) (d) No bypasses occur that are not approved by the department; and

NR 212.12(2)(e) (e) The municipality has taken all reasonable steps to obtain federal and state financing for its point source.

NR 212.12(3) (3) The use of instream aeration under sub. (2) shall be allowed for a period not to exceed 5 years, at which time the publicly-owned point source shall have sufficient treatment capability in place to meet the waste water treatment needs as required by an approved municipal waste water treatment facility plan developed under ch. NR 110.

NR 212.13(1)(b) (b) A technical analysis is presented to the satisfaction of the department which determines the critical water quality conditions for the affected stream segment as a function of the flow reregulation technique.

NR 212.13(1)(c) (c) Legally binding assurances are provided to the satisfaction of the department that the entity responsible for reregulating flows on the affected stream segment will undertake the agreed-upon flow reregulation activities.

NR 212.13(1)(d) (d) The flow reregulation does not interfere with the uses for which the impoundment was authorized.

NR 212.13(2) (2) Flow reregulation may not be used to accommodate new discharges of pollutants either from new point sources or from the expansion of existing point sources.

NR 212.13(3) (3) Flow reregulation may not be accomplished by the construction of new impoundments built for the primary purpose of increasing flows to accommodate pollution loadings.

NR 212.13(4) (4) Flow reregulation may not be accomplished by flow augmentation practices which would increase the overall quantity of surface water in the basin. Prohibited practices include interbasin transfers or groundwater pumping.

NR 212.40(4)(b) (b) The adjusted baseline load for each nonpublicly-owned point source shall be calculated as follows:

NR 212.40(4)(c) (c) The adjusted baseline load for publicly-owned and nonpublicly-owned point sources from milepoints 32.4 through 19.2 shall include an incremental addition as follows:

NR 212.40(4)(d) (d) The adjusted baseline load for nonpublicly-owned point source located between milepoint 0.8 and 0.5 shall be reduced by 2500 pounds of BOD5 from the amount calculated in par. (b).

NR 212.40(5) (5) Determine the allocation for each point source. The allocation for each point source shall be calculated as follows:

NR 212.40(6) (6) For purposes of determining compliance with water quality related effluent limits, the following conditions shall be met:
