Each potential drinking water works project is assigned points based on the criteria in the following table:

1. (1) Occurrences of nitrates, fecal coliform, or E. Coli bacteria in samples within the past three years have exceeded the allowable limits as defined in chapter 74:04:12, and this project will address the suspected cause of these occurrences;

   150 points

   or

   occurences of an emerging contaminant in samples within the past three years, and this project will address the suspected cause of these occurrences or provide an alternative water source to replace a source or sources contaminated with an emerging contaminant;

   100 points

   or

   occurrences of chronic primary drinking water contaminants in samples within the past three years have exceeded the allowable limits as defined in chapter 74:04:12 or the system is in violation of a treatment technique, and this project will address the suspected cause of these occurrences or correct the treatment technique violation;

   100 points

   (Maximum

   Points = 150)

2. (2) Affordability criteria:

   1. (a) Greater than 1.0 percent for community water systems whose median household income is less than or equal to $54,000; or
   2. (b) Greater than 1.5 percent for community water systems whose median household income is more than $54,000;

   75 points

3. (3) Consolidation of facilities where:

   1. (a) One or more community water systems consolidate with another community water system and the consolidation is cost effective;

      50 points

   2. (b) A community water system will receive water from another community water system but will continue to operate its water system in some capacity;

      25 points

4. (4) Occurrences of secondary drinking water contaminants in samples within the past three years have exceeded the guidelines, and this project will address the suspected cause of these occurrences. The specific contaminants and the maximum contaminant level are:
