Wisconsin Administrative Code › Department of Natural Resources › NR 100-199 - Environmental Protection - General › Chapter NR 101 - Reports and fees for wastewater discharges › Section NR 101.13 - Wastewater fees

Current through June 24, 2024
An annual wastewater fee shall be assessed to each facility
				  holding a specific WPDES permit and reporting discharges during the calendar
				  year:
(1) The annual wastewater fee
				shall consist of the greater of the base fee under sub. (2) or a discharge fee
				under sub. (3). The effect of this section is to assess fees to each holder of
				a specific WPDES permit.
(2) The
				base fee shall be $500 for facilities classified as a major permittee or $250
				for facilities classified as a minor permittee.
(3) The discharge fee shall be the total of
				fees for individual pollutants determined by multiplying the 5-year rolling
				average of the product of the effluent quantities from s.
				NR
				101.12(5) times the applicable limit
				rate determined in accordance with sub. (4), times the adjustment factor. The
				adjustment factor for municipal dischargers is 2.4510 and for other dischargers
				is 5.0492.
Note: The adjustment factors identified in sub. (3) were
				  calculated and applied to calendar year 1999 fees to satisfy the requirement in
				  s.
				  299.15(3)
				  (e) 3, Stats.
(4) The limit rate for each month of
				discharge shall be based on the limit from one of the following:
(a) An effluent limit expressed as a
				concentration for the discharge of a pollutant. The limit rate in dollars per
				pound for a pollutant is the inverse of the effluent limit when the effluent
				limit is expressed in units of milligrams per liter. If more than one such
				limit is in effect for the same pollutant in a permit, the limit which yields
				the highest limit rate shall be used.
(b) A water quality based effluent limit
				under s.
				283.13(5),
				Stats., and expressed in units of pounds per day for the discharge of a
				pollutant where no effluent limit under par. (a) is in effect for the same
				pollutant. A concentration factor expressed in units of milligrams per liter
				shall be calculated by dividing the mass limit by the product of the industrial
				annual average discharge flow, or municipal design flow, times 8.34. The limit
				rate in dollars per pound is the inverse of the concentration factor. If more
				than one water quality-based mass limit is in effect for the same pollutant in
				a permit, the mass limit which yields the highest limit rate shall be used for
				the rate calculation for that pollutant.
(c) A categorical effluent limit under s.
				283.13(2),
				Stats., and expressed in units of pounds per day for the discharge of a
				pollutant where there is no effluent limit under par. (a) for the same
				pollutant. The limit rate for BOD5 shall be $0.03 per pound, for total
				suspended solids shall be $0.02 per pound, and for other pollutants shall be a
				rate calculated as in par. (b) substituting the categorical limit for water
				quality based effluent limit.
(d)
				Where a water quality based effluent limit and a categorical limit are in
				effect for the same pollutant in a permit, and there is no effluent limit under
				par.
(a) for the pollutant, the water quality
				based effluent limit shall be used to calculate the limit rate as in par.
(b).
(e) An effluent standard based limit under
				ch. NR 217. The limit rate for phosphorus shall be $0.34 per pound.
(f) For groundwater discharges the limit rate
				shall be calculated as in par. (a), (b) or (c), except that the limit rate for
				BOD and total suspended solids shall be $0.00 per pound and for nitrogen above
				the yearly crop nutrient uptake rate shall be $0.10 per pound and for chloride
				shall be $0.008 per pound. The crop nutrient uptake rate to be used for this
				paragraph shall be those published in USGS-SCS-Wisconsin Section IV Technical
				Guide 633 table 207/87.
