Iowa Admin. Code r. 567-91.8

Current through Register Vol. 47, No. 11, December 11, 2024
Rule 567-91.8 - Project priority rating system
(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.

Use and Classification Points
Outstanding Iowa waters 45
High quality waters 40
High quality resource waters 20
Class Al waters 50
Class A2 waters 45
Class A3 waters 45
Class C waters 40
Class B (CW1) waters 50
Class B (CW2) waters 30
Class B (WW1) & HH waters 30
Class B (WW2) waters 25
Class B (WW3) waters 20
Class B (LW) waters 35

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.

Indication of water quality Points
A
Integrated Report of impaired waters status
4a, 4b, 4c, 4d, or 5a 15
5b 10
5p 5
B
Section 305(b) status
Aquatics or fish consumption or drinking water
Fully supporting 5
Partially supporting 10
Not supporting 15
Not assessed 7
Recreation
Fully supporting 5
Partially supporting 10
Not supporting 15
Not assessed 7

c. Protection of groundwater resources. This category considers the use of the aquifer affected by the project.

Groundwater Category Points
Wellhead protection area for public water supply 40
Unconfined aquifer that serves as a drinking water source 20
Other groundwater protection 10

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.

Project Type Points
Category I. Secondary wastewater treatment 40
Category II. Advanced wastewater treatment 50
Category III-A. Infiltration/inflow correction 30
Category III-B. Sewer replacement/rehabilitation 30
Category IV-A. New collector sewers and appurtenances 10
Category IV-B. New interceptor sewers and appurtenances 20
Category V. Combined sewer overflow correction 40
Category VI. Storm water conveyance treatment systems and green infrastructure 30
Category VII-A. Agriculture (cropland) 30
Category VII-B. Agriculture (animals) 50
Category VII-C. Silviculture 10
Category VII-E. Groundwater protection (unknown sources) 20
Category VII-F. Marinas 10
Category VII-G. Resource extraction 10
Category VII-H. Brownfields 30
Category VII-I. Storage tanks 20
Category VII-J. Landfills 30
Category VII-K. Hydromodification 40
Category X. Recycled water distribution 10
Category XII. Decentralized sewage treatment 40
Refinance of existing projects that meet CWSRF eligibility criteria 5

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.

Project Purpose Points
Allows facility to meet new water quality standards 50
Protects or restores the physical, chemical, and biological integrity of water resources at a specific site 50
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 40
Provides regional consolidation in wastewater treatment or system management 30
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) 25

Eliminates or remediates a source of groundwater pollution 20
Meets existing or reasonable future needs of the community in order to maintain compliance with an NPDES permit 15
Provides operational reliability improvements, apart from projects which address compliance and enforcement 10

f.Total points. Total points are ca1culated 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:

*Use Classification of Receiving Streams

*Water Quality of Receiving Streams (a+b)

* Groundwater Protection

*Project Type

*Project Purpose

(2) Reserved.
