Current through June 24, 2024
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.
(1) The department shall determine baseline
				  loads for each point source subject to the wasteload allocation in accordance
				  with all of the following:
(a) The baseline
				  load for each publicly-owned point source located between milepoints 205.3 and
				  171.9 shall be calculated as follows:
Baseline Load = (Q) (8.34) (60) (C)
Where Q = The average daily flow for the publicly- owned
					 point source during 1978 expressed in millions of gallons per day .
8.34 = Conversion factor (lbs./gal.).
60 = Concentration of BOD 5 expressed in milligrams per
					 liter.
C = Reallocation conversion factor which has a value of
					 1.0 for the publicly-owned point source located between milepoints 205.3 and
					 199.4 and a value of 1.18 for the publicly-owned point sources located between
					 milepoints 199.3 and 171.9.
(b) The baseline load for each
				  nonpublicly-owned point source located between milepoints 205.3 and 171.9 shall
				  be calculated as follows:
Baseline Load = (BPT) (Production)
Where BPT = The final best practicable waste treatment
					 effluent limitations for the point source as provided in ch. NR 284, expressed
					 as pounds of BOD5 per ton of production. If ch. NR 284 does not apply , the
					 best practicable waste treatment effluent limitations as determined under ch.
					 NR 220 shall apply.
Production = The annual average off-machine production
					 during 1978 expressed as tons per day.
(c) The baseline load for each publicly-owned
				  point source located between milepoints 235.4 and 271.1 shall be calculated as
				  follows:
Baseline Load = (Q) (8.34) (C)
Where Q = 0.55 million gallons per day for publicly- owned
					 point sources located between milepoints 240.0 and 250.0 4.0 million gallons
					 per day for publicly- owned point sources located between milepoints 250.0 and
					 260.0. 8.2 million gallons per day for publicly- owned point sources located
					 between milepoints 260.0 and 265.0. 0.1 million gallons per day for publicly-
					 owned point sources located between milepoints 265.0 and 271.1.
8.34 = Conversion factor (lbs./gal.).
C = 45 milligrams per liter concentrations of
					 BOD5 for publicly-owned point sources located between
					 milepoints 240.0 and 250.0, 250.0 and 260.0, and 265.0 and 271.1
60 milligrams per liter concentration of
					 BOD5 for publicly-owned point sources located between
					 milepoints 260.0 and 265.
(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:
Baseline Load = (BPT) (Production)
Where BPT = The final best practicable waste treatment
					 effluent limitations for the point source as provided in ch. NR 284, or 220,
					 when applicable, expressed as pounds of BOD5 per ton of production.
Production = The maximum weekly off-machine production
					 during 1981 expressed as tons per day
(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:
Baseline Load = (BPT) (Production)
Where BPT = The final best practicable waste treatment
					 effluent limitations for the point source as provided in ch. NR 284 or 220,
					 when applicable, expressed as pounds of BOD5 per ton of production.
Production = The average weekly off-machine production
					 expressed as tons per day from March to December 1973 for point sources located
					 between milepoints 271.0 and 258.5 and the BPT permit limits for 1978 for point
					 sources located between milepoints 258.4 and 258.2 and the average weekly
					 off-machine production expressed as tons per day during 1974 for point sources
					 located between milepoints 258.19 and 249.0 and the average weekly off-machine
					 production expressed as tons per day during 1973 plus the woodroom allowance
					 for sources located between milepoints 248.9 and 240.0.
(f) The baseline load for each publicly-owned
				  point source located between milepoints 341.4 and 305.9 shall be calculated as
				  follows:
Baseline Load = (Q) (8.34) (30)
Where Q = The design flow for the publicly-owned point
					 source located between milepoints 341.4 and 313.2 and the year 2000 flow
					 projection for those located between milepoints 313.3 and 305.9 expressed in
					 millions of gallons per day.
8.34 = Conversion factor (lbs/gal.).
30 = Concentration of BOD5
					 expressed in milligrams per liter
(g) The baseline load for each
				  nonpublicly-owned point source located between milepoints 341.4 and 305.9 shall
				  be calculated as follows:
Baseline Load = (BPT) (Production)
Where BPT = The final best practicable waste treatment
					 effluent limitations for the point source as provided in ch. NR 284, expressed
					 as pounds of BOD5 per ton of production. If ch. NR 284 does not apply , the
					 best practicable waste treatment effluent limitations as determined under ch.
					 NR 220 shall apply.
Production = The annual average off-machine production
					 during 1978 expressed as tons per day.
