91.8(1)Rating criteria. The rating criteria consider the use classification of the receiving waters, water quality of the receiving waters, groundwater protection, project type, project purpose, and a tiebreaker. Priority ranking for the projects shall be based on the total points awarded for all the categories; the greater the total number of points, the higher the ranking. For POTW projects, the ranking will be done at the time the IUP is prepared. For nonpoint source projects, if 90 percent of the set-aside is allocated, the ranking will be done at the time the project application is received. The tiebreaker category will be used when necessary.
a. Use classification of receiving waters. This category addresses the receiving water that is impacted or potentially impacted by the existing situation and that would be improved or protected by the proposed project. Points shall be awarded and shall be cumulative for all designated use classifications of the receiving stream. Points for sludge stabilization, sewers and lift station projects normally will be based on the assigned use of the waters that receive or could receive the effluent discharge.
b. Water quality of receiving waters. This category addresses the quality of water in the receiving stream and whether or not the water has been designated as impaired for some uses. Bodies of water that are impaired by pollutants are identified as the Section 303(d) list of waters in the integrated report of impaired waters status. The Section 303(d) list of waters also identifies probable pollutant source categories for these impairments. Projects that primarily impact these waters are awarded points if the water body that receives or could receive the wastewater discharge is included on the Section 303(d) list and the probable pollutant source is a point source. Waters are also identified in the Section 305(b) report on their use attainment status. Projects that primarily impact these waters are awarded points depending on the use impairment identified for the water body that receives or could receive the wastewater discharge. If no use impairment is identified indicating the water was not assessed, the partially supporting status points will be awarded. Points will be awarded for both A and B of the table below and then totaled for this category.
c. Protection of groundwater resources. This category considers the use of the aquifer affected by the project.
Wellhead protection area for public water supply
Unconfined aquifer that serves as a drinking water source
Other groundwater protection
d. Project type. In this category, points are provided based on the type of project and the relative level of the impact on public health and the environment. Points will be awarded only for the primary project type.
e. Project purpose. In this category, points are awarded based on the purpose and expected outcome of the project. Points will be awarded only for the primary purpose.
Allows facility to meet new water quality standards
Protects or restores the physical, chemical, and biological integrity of water resources at a specific site
Reduces the loading of a parameter that has been identified as an impairment to the receiving water or watershed as identified through the total maximum daily load (TMDL) process
Provides regional consolidation in wastewater treatment or system management
Brings facility into compliance with a National Pollution Discharge Elimination System (NPDES) permit or other administrative or judicial enforcement action as may be required by the department or U.S. Environmental Protection Agency (EPA)
Meets existing or reasonable future needs of the community in order to maintain compliance with an NPDES permit
Provides operational reliability improvements, apart from projects which address compliance and enforcement
f. Total points. Total points are calculated using the following formula:
Total Points = Use Classification + Water Quality or Groundwater Protection + Project Type + Project Purpose
g. Tiebreaker. Two or more projects may receive the same total points on the fundable list. If sufficient state revolving loan funds are not available to fund the projects, ties will be broken by determining which project has the highest score in each category in the following order:
