NR 166.23(3)(a)2.c.c. For MCL exceedances in more than one subgroup, the highest point level of the subgroups shall be used as the primary number to be divided by the current MCL or AL and then multiplied by 50. The other subgroup exceedances will be divided by their respective MCL or AL and then multiplied by 10. The total point value shall be the sum of points in each subgroup. NR 166.23(3)(b)(b) Anticipated violations and exceedances. Project prevents an anticipated MCL, AL, or treatment technique violation or critical health hazard. Points shall be awarded to a single group under either subd. 1. or 2. to a project that proposes to eliminate an anticipated acute or chronic health hazard under the following requirements: NR 166.23(3)(b)1.1. ‘Acute contaminants.’ Acute contaminants are divided into 3 groups. Points shall be awarded from one of the following groups for a project that eliminates an anticipated acute health hazard: NR 166.23(3)(b)1.a.a. Three hundred points shall be awarded to a project that eliminates an anticipated microbiological MCL violation, where no actual violation has yet occurred. NR 166.23(3)(b)1.b.b. Two hundred points shall be awarded to a project that proposes to eliminate anticipated violations of filtration requirements, or turbidity, in s. NR 810.29, or anticipated violations of the requirements of the federal long term 2 enhanced surface water treatment rule promulgated by the U.S. environmental protection agency as directed by the U.S. congress. NR 166.23(3)(b)1.c.c. One hundred points shall be awarded to a project that proposes to eliminate an anticipated nitrate or nitrite violation. NR 166.23(3)(b)2.2. ‘Chronic contaminants.’ Chronic contaminants are divided into 5 subgroups: inorganics, volatile organic chemicals, synthetic organic chemicals, radionuclides, and disinfection byproducts. Points shall be awarded in the following manner for a project that eliminates an anticipated chronic health hazard from these groups of chemicals: NR 166.23(3)(b)2.a.a. Twenty points shall be awarded to a project that proposes to eliminate an anticipated exceedance of an inorganic, volatile organic chemical, synthetic organic chemical, radionuclide, or disinfection byproducts contaminant. NR 166.23(3)(b)2.b.b. Five points shall be awarded for each additional subgroup addressed by a project that eliminates an anticipated exceedance. NR 166.23(3)(c)(c) Private LSL replacement. Points shall be awarded to watermain replacement projects that also include the replacement of private LSLs under the following defined quantities: NR 166.23(3)(c)1.1. Thirty points shall be awarded if at least 200 private LSLs are being removed as part of the project. NR 166.23(3)(c)2.2. Twenty-five points shall be awarded if at least 100 private LSLs but less than 200 are being removed as part of the project. NR 166.23(3)(c)3.3. Twenty points shall be awarded if at least 50 private LSLs but less than 100 are being removed as part of the project. NR 166.23(3)(c)4.4. Fifteen points shall be awarded if at least 25 private LSLs but less than 50 are being removed as part of the project. NR 166.23(3)(c)5.5. Ten points shall be awarded if at least 15 private LSLs but less than 25 are being removed as part of the project. NR 166.23(3)(c)6.6. Four points shall be awarded if less than 15 private LSLs are being removed as part of the project. NR 166.23(3)(c)7.7. Ten additional points shall be awarded if the project will remove all remaining private LSLs in the municipality. NR 166.23(4)(4) Secondary contaminant violation or system compliance with ch. nr 811. The department may not award points for specific areas related to secondary contaminant violations or system compliance with ch. NR 811 if the project is already receiving points under sub. (1) for the same issue. The department shall assign points to a project for any of the following criteria that are applicable to the project: NR 166.23(4)(a)(a) Twenty points shall be awarded if the project will reduce a secondary drinking water contaminant, as listed in s. NR 809.70, to a level below the aesthetic standard. NR 166.23(4)(c)(c) Twenty points shall be awarded if the project will address a documented storage deficiency, excluding fire demand, within an existing public water supply system. NR 166.23(4)(d)(d) Twenty points shall be awarded if the project addresses a source or capacity deficiency where there is a demonstrated need within the existing public water supply system. NR 166.23(4)(e)(e) Twenty points shall be awarded if the project will address system reliability under all operational situations, where there are significant concerns regarding reliability in the existing system, such as lack of redundancy of major components of the water system. Activities for which these points may be awarded include the addition of a second crossing of a river, railroad, or highway to a major system divide; installation of a second surface water intake; or construction of a second well. NR 166.23(4)(f)(f) Twenty points shall be awarded if a major portion of the project will address significant deficiencies identified in a sanitary survey conducted by the department and the activities to correct deficiencies are related to the scored project activities. NR 166.23(4)(g)(g) Four points shall be awarded if the project replaces lead joints in water mains. NR 166.23(4)(h)(h) Four points shall be awarded if the project includes long–term zebra mussel control. NR 166.23(4)(i)(i) Four points shall be awarded if the project includes installation of an auxiliary power source to a well, pump station, or water treatment plant. NR 166.23(4)(j)(j) Four points shall be awarded if the project includes replacement of asbestos–cement pipe material. NR 166.23(4)(k)(k) Four points shall be awarded if the project includes upgrading an existing supervisory control and data acquisition system.
