NR 162.03 NR 162.03 Project eligibility.

NR 162.03(1) (1) Traditional wastewater treatment plant and collection system projects. A municipality may receive financial assistance under this chapter for a publicly-owned wastewater treatment works scored project, including a treatment plant or sewage collection system project, that meets any of the following criteria:

NR 162.03(1)(a) (a) The project is necessary to prevent a municipality from significantly exceeding a wastewater effluent limitation contained in a permit issued under ch. 283, Stats. All of the following types of projects are included under this paragraph:

NR 162.03(1)(a)1. 1. Projects for which construction will completely take place inside the fence or on site of a wastewater treatment plant, such as projects to build or modify headworks, clarifiers, aeration basins, stabilization ponds, sludge processing equipment, sludge storage facilities, or on-site administrative buildings, and projects to build or modify facilities for the receiving, storage, or treatment of septage. The department may determine that a lift station pumping all of the wastewater flow directly to the wastewater treatment plant with no other influent pump at the plant site is part of a project that takes place inside the fence. The department may also determine, based on the layout and function of the treatment work, that other facilities, such as a septage receiving station that conveys the septage directly into the wastewater treatment plant, are considered part of the work inside the fence.

NR 162.03(1)(a)2. 2. Projects for which construction takes place outside of the fence of the wastewater treatment plant that are necessary to maintain or improve the integrity and performance of wastewater treatment works facilities serving the municipality, including sanitary sewer replacement or rehabilitation, sanitary sewer lining, publicly-owned lateral lining, lift station upgrades, and construction of new interceptors, lift stations, pretreatment facilities, septage receiving stations, and other treatment works facilities outside of the fence of the wastewater treatment plant.

NR 162.03(1)(b) (b) The project is necessary to achieve compliance with an enforceable wastewater requirement changed or established after May 17, 1988, if the municipality is in substantial compliance with its permit issued under ch. 283, Stats.

NR 162.03(1)(c) (c) The project is necessary to correct violations of an effluent limitation contained in a permit issued under ch. 283, Stats.

NR 162.03(1)(d) (d) The project is necessary to eliminate actual or imminent pollution of groundwater or surface water or a threat to human health in unsewered areas within a municipality. All of the following types of projects are included under this paragraph:

NR 162.03(1)(d)1. 1. Projects for construction of a new wastewater treatment plant or upgrade of an existing plant to accept and treat wastewater from a previously unsewered area, such as projects to build or add capacity to clarifiers, aeration basins, stabilization ponds, or sludge facilities.

NR 162.03(1)(d)2. 2. Sewage collection system projects to install sewer pipes where there were none and interceptors to carry wastewater to a new or existing wastewater treatment plant.

NR 162.03 Note Note: The projects described under this subsection are considered “traditional wastewater treatment plant and collection system projects” and are those that use common infrastructure and processes to collect and treat wastewater, including pipes to collect wastewater from homes and businesses and carry the water to a treatment plant that uses techniques and equipment to filter and settle out solids, aerate the water to encourage natural processes of growth of bacteria and other organisms to consume much of the waste, disinfect the processed water, and process the sludge removed from the wastewater. Traditional projects tend to collect and treat point-source pollution only, unless storm sewers contribute to the flow of water to the wastewater treatment plant or the system has infiltration or inflow problems. The purpose of some traditional projects is to fix these types of excess flow issues. Traditional wastewater treatment is discussed in the Primer for Municipal Wastewater Treatment Systems, Publication EPA 832-R-04-001, dated September 2004, available on the U.S. environmental protection agency’s website at https://www.epa.gov/sites/default/files/2015-09/documents/primer.pdf.

NR 162.03(2)(a) (a) A project that is eligible under sub. (1) may consist of individual systems that serve one or more properties for the purpose of treating sanitary waste if the municipality meets all of the following criteria:

NR 162.03(2)(a)1. 1. The municipality owns each individual system.

NR 162.03(2)(a)2. 2. The municipality is responsible for the proper installation, operation, and maintenance of each individual system.

NR 162.03(2)(a)3. 3. The municipality has unlimited access to each individual system at all reasonable times for the purposes of inspection, monitoring, construction, maintenance, operation, rehabilitation, and replacement of the system.

NR 162.03(2)(a)4. 4. The municipality establishes a comprehensive program for the regulation, inspection, operation, and maintenance of individual systems, and for monitoring the impact of the systems on groundwater where required by the department.

NR 162.03(2)(a)5. 5. The municipality complies with all other applicable requirements, limitations, and conditions for projects funded under this chapter.

NR 162.03(2)(b) (b) The access required under par. (a) 3. shall be established through easements, covenants running with the land, or local ordinance. The department may require that the program established under par. (a) 4. include periodic testing of water from existing potable water wells and monitoring of aquifers in the area.

NR 162.03(2)(c) (c) Individual wastewater treatment systems include cluster systems, mound systems, holding tanks, septic tanks, pipes to transport wastewater, and other alternative systems for small communities.

NR 162.03(3) (3) Storm water projects. A municipality may receive financial assistance under this chapter in accordance with subch. III or IV for a publicly owned project that is necessary to control storm water runoff pollution in order to achieve water quality standards.

NR 162.03(4) (4) Ineligible projects. The department may determine that an entire project or a portion of a project is ineligible for CWFP financial assistance. If the department determines that a portion of a project is ineligible, it shall specifically identify the ineligible portion and the associated costs, or prorate the amount of financial assistance provided to reflect the appropriate proportion of eligible to ineligible project costs, or both, in the financial assistance agreement.
