NR 212.60NR 212.60 Determination of upper Wisconsin river water quality related effluent limitations. Effluent limitations for point sources discharging BOD5 to the upper Wisconsin river shall be calculated according to the procedures contained in this section. These limitations shall apply from May 1 to October 31 annually.

NR 212.60(1)(1) The department shall determine baseline loads for each point source subject to the wasteload allocation in accordance with all of the following:

NR 212.60(1)(a)(a) The baseline load for each publicly-owned point source located between milepoints 205.3 and 171.9 shall be calculated as follows:

NR 212.60(1)(b)(b) The baseline load for each nonpublicly-owned point source located between milepoints 205.3 and 171.9 shall be calculated as follows:

NR 212.60(1)(c)(c) The baseline load for each publicly-owned point source located between milepoints 235.4 and 271.1 shall be calculated as follows:

NR 212.60(1)(d)(d) The baseline load for each nonpublicly-owned point source with best practicable waste treatment effluent limitations of less than 500 pounds per day located between milepoints 271.1 and 240.0 shall be calculated as follows:

NR 212.60(1)(e)(e) The baseline load for each nonpublicly-owned point source with best practicable waste treatment effluent limitations of BOD5 equal to or exceeding 500 pounds per day located between milepoints 271.1 and 240.0 shall be calculated as follows:

NR 212.60(1)(f)(f) The baseline load for each publicly-owned point source located between milepoints 341.4 and 305.9 shall be calculated as follows:

NR 212.60(1)(g)(g) The baseline load for each nonpublicly-owned point source located between milepoints 341.4 and 305.9 shall be calculated as follows:

NR 212.60(2)(a)(a) The allocation for each publicly-owned point source located between milepoints 205.3 and 171.9 shall be its baseline load as determined in sub. (1) (a).

NR 212.60(2)(b)(b) The allocation for each nonpublicly-owned point source located between milepoints 205.3 and 171.9 shall be calculated as follows:

For purposes of determining compliance with water quality related effluent limits, the following conditions shall be met:

NR 212.60(2)(b)1.1. The sum of the actual daily discharges for any 5-consecutive-day-period may not exceed the sum of the daily point source allocation values calculated under the formula for the same 5-consecutive-day-period; and

NR 212.60(2)(b)2.2. For any one day period, the actual discharge for the point source may not exceed 120.5% of the allocation for that day as calculated under the formula.

NR 212.60(2)(c)1.1. The allocation for publicly-owned point source located between milepoint 240.0 and 250.0 shall be its baseline load as determined under sub. (1) (c).

NR 212.60(2)(c)2.2. The allocation for publicly-owned point sources located between milepoint 250.0 and 260.0 shall be determined as follows:

NR 212.60(2)(c)2.a.a. For the period January 1, 1986 through December 31, 1990, the allocation shall be determined as follows:

Point Source Allocation = (Q) (8.34) (45)
Where Q = 3.1 million gallons per day
8.34 = Conversion factor (lbs./gal.)
45 = 45 milligrams per liter concentration of BOD5

NR 212.60(2)(c)2.b.b. For each 5-year period beginning January 1, 1991 through December 31, 2005, the allocation shall be redetermined on the basis of projected flows and the demonstrated treatment capability of the point source. The redetermination shall be made at the time of each 5-year reevaluation under s. NR 212.06 (2). No allocation may exceed the baseline load as determined in sub. (1) (c).

NR 212.60(2)(c)3.3. The allocation for the publicly-owned point sources located between milepoints 260.0 and 265.0 shall be a reduction in discharge to levels appearing in Table 8-m. For purposes of determining compliance with water quality related effluent limits, the following conditions shall be met:

NR 212.60(2)(c)3.a.a. The sum of actual daily discharges for any 5-consecutive-day period may not exceed the sum of the daily point source allocation values calculated for the same 5-consecutive-day period.

NR 212.60(2)(c)3.b.b. For any one day period, the actual discharge for the point source may not exceed 108.5% of the allocation for that day calculated for those flow temperature regimes identified as Condition A in Table 8-m or 101.8% of the allocation for that day calculated for those flow/temperature regimes identified as Condition B in Table 8-m or 113.0% of the allocation calculated for those flow/temperature regimes identified as Condition C in Table 8-m.

NR 212.60(2)(c)4.4. The allocation for publicly-owned point sources located between milepoints 265.0 and 271.1 shall be its baseline load as determined under sub. (1) (c).

NR 212.60(2)(d)(d) The allocation for each nonpublicly-owned point source located between milepoints 271.1 and 240.0 with best practicable waste treatment effluent limits of less than 500 pounds of BOD5 per day shall be its baseline load as determined under sub. (1) (d).

NR 212.60(2)(e)(e) The allocation for each nonpublicly-owned point source located between milepoints 271.1 and 258.5 with best practicable waste treatment effluent limits equal to or exceeding 500 pounds of BOD5 per day shall be a reduction in its discharge to levels appearing in Table 2-m. For purposes of determining compliance with water quality related effluent limits, the following conditions shall be met:

NR 212.60(2)(e)1.1. The sum of the actual daily discharges for any 5-consecutive-day period may not exceed the sum of the daily point source allocation values calculated under Table 2-m for the same 5-consecutive-day period.

NR 212.60(2)(e)2.2. For any one day period, the actual discharge for the point source may not exceed 101.8% of the allocation for that day calculated for those flow/temperature regimes identified as Condition B in Table 2-m or 113.0% of the allocation calculated for those flow/temperature regimes identified as Condition C in Table 2-m. No percentage adjustment shall be made for conditions identified as Condition A in Table 2-m.
