(1) The board shall promulgate rules and regulations to establish and implement the community public water system letter grade schedule provided for in Sections 41-26-201 through 41-26-211. The rules and regulations shall provide clear and appropriate point values for the criteria established in accordance with this section to calculate the community public water system’s letter grade. Point values shall be based on objective criteria so that each community public water system is assessed equally and fairly. Community Public Water Systems shall be assigned a letter grade of “A”, “B”, “C”, “D”, or “F”. A consolidated score and letter grade shall be calculated on a weighted-average basis for any person owning more than one (1) community public water system in the state.
(2) For each community public water system, the board shall publish on its website an annual report summarizing the board’s assessment, scores and letter grade. Every community public water system shall provide notification to its customers of the board’s published score and letter grade within thirty (30) days following publication by the board in a manner to be established by regulation by the board.
