NR 162.49(1)(c)2.b.b. The recipient will abandon its own existing treatment facility and construct new infrastructure to convey its wastewater to an existing treatment facility owned by another municipality.
NR 162.49(2)(2)Wastewater treatment plant projects. The following factors, when applied to wastewater treatment plant projects in accordance with s. NR 162.50, shall determine the priority scoring for CWFP financial assistance under s. 281.58, Stats.:
NR 162.49(2)(a)(a) Project type score. The following points shall be awarded to each wastewater treatment plant project:
NR 162.49(2)(a)1.1. Fifty points to a project meeting the criteria of s. NR 162.03 (1) (a) 1., necessary to prevent a municipality from significantly exceeding an effluent limitation contained in a permit issued under ch. 283, Stats.
NR 162.49(2)(a)2.2. Fifty points to a project eligible under s. NR 162.03 (1) (b), required to meet new or changed WPDES permit limits.
NR 162.49(2)(a)3.3. Five points to a project meeting the criteria under s. NR 162.03 (1) (c), necessary to correct violations of an effluent limit contained in a permit issued under ch. 283, Stats.
NR 162.49(2)(b)(b) Human health criteria. Projects that directly affect human health shall be awarded points based on the following criteria:
NR 162.49(2)(b)1.1. Ten points if the project is necessary to prevent bypasses and overflows at a wastewater treatment plant that has had at least one occurrence of bypass or overflow, as defined in s. NR 210.21, within the 5 years prior to the most recent submittal deadline for priority evaluation and ranking form information.
NR 162.49(2)(b)2.2. Five points if the project is necessary to eliminate documented system-related backups that occurred within the 5 years prior to the most recent submittal deadline for priority evaluation and ranking form information caused by conditions at the wastewater treatment plant but not including backups caused by problems in the sewage collection system or backups due to excessive infiltration and inflow.
NR 162.49(2)(b)3.3. Ten points if the wastewater treatment works discharges to groundwater.
NR 162.49(2)(b)4.4. Ten points if the wastewater treatment works has a groundwater discharge and an effluent limit for total nitrogen.
NR 162.49(2)(b)5.5. Five points if the wastewater treatment works has a groundwater discharge and an effluent limit for any compounds other than nitrogen, such as a limit for chlorides. The maximum number of points under this subdivision is 5.
NR 162.49 NoteExample – If a treatment works has a groundwater discharge and an effluent limit for chlorides and an effluent limit for phosphorus, the department shall award only 5 points in this subdivision, even though there are 2 compounds for which the permit includes effluent limits.
NR 162.49(2)(b)6.6. Five points if the wastewater treatment works’ permit requires annual disinfection prior to discharge.
NR 162.49(2)(b)7.7. Three points if the wastewater treatment works’ permit requires disinfection but on a less than annual basis prior to discharge.
NR 162.49(2)(c)(c) Water quality criteria. The department shall award points for water quality parameters, based on the facility’s WPDES permit limits. The department shall use surface water effluent limits in the current WPDES permit when determining the appropriate points to assign in the water quality criteria category as follows:
NR 162.49(2)(c)1.1. For BOD limits, the department shall assign points as follows, unless the permit includes a CBOD limit that provides a higher number of points:
NR 162.49(2)(c)1.a.a. Sixteen points if the monthly permit limit for BOD, or the most stringent seasonal limit for BOD in the permit, is less than 10 mg/l.
NR 162.49(2)(c)1.b.b. Twelve points if the monthly permit limit for BOD, or the most stringent seasonal limit for BOD in the permit, is 10 or more mg/l but less than 15 mg/l.
NR 162.49(2)(c)1.c.c. Eight points if the monthly permit limit for BOD, or the most stringent seasonal limit for BOD in the permit, is 15 or more mg/l but less than 20 mg/l.
NR 162.49(2)(c)1.d.d. Five points if the monthly permit limit for BOD, or the most stringent seasonal limit for BOD in the permit, is 20 or more mg/l but less than 30 mg/l.
NR 162.49(2)(c)1.e.e. Two points if the monthly permit limit for BOD, or the most stringent seasonal limit for BOD in the permit, is 30 or more mg/l.
NR 162.49(2)(c)2.2. For CBOD limits, the department shall assign points as follows, unless the permit includes a BOD limit that provides a higher number of points:
NR 162.49(2)(c)2.a.a. Sixteen points if the monthly permit limit for CBOD, or the most stringent seasonal limit for CBOD in the permit, is less than 10 mg/l.
NR 162.49(2)(c)2.b.b. Twelve points if the monthly permit limit for CBOD, or the most stringent seasonal limit for CBOD in the permit, is 10 or more mg/l but less than 15 mg/l.
NR 162.49(2)(c)2.c.c. Eight points if the monthly permit limit for CBOD, or the most stringent seasonal limit for CBOD in the permit, is 15 or more mg/l but less than 20 mg/l.
NR 162.49(2)(c)2.d.d. Five points if the monthly permit limit for CBOD, or the most stringent seasonal limit for CBOD in the permit, is 20 or more mg/l but less than 25 mg/l.
NR 162.49(2)(c)2.e.e. Two points if the monthly permit limit for CBOD, or the most stringent seasonal limit for CBOD in the permit, is 25 or more mg/l.
NR 162.49(2)(c)3.3. For TSS limits, the department shall assign points as follows:
