NR 110.09NR 110.09Sewage treatment facilities projects.
NR 110.09(1)(1)Facilities plans for sewage treatment facilities projects.
NR 110.09(1)(a)(a) Facilities plans consist of those necessary plans and studies which directly relate to the construction of the proposed facilities. Facilities planning shall demonstrate the need for the proposed facilities. Through a systematic evaluation of feasible alternatives facilities planning shall also demonstrate that the selected alternative is the most cost-effective means of meeting established effluent limitations and water quality standards. The most cost-effective alternative is that which will result in the minimum total resources costs over the planning period. The planning period of the facilities plan shall be 20 years. The total resources costs include monetary costs, environmental and social considerations, and other nonmonetary factors. The interest (discount) rate to be used in calculating present worth shall be obtained from the department when beginning facilities planning.
NR 110.09(1)(b)(b) Facilities planning shall include the following information in such detail as the department deems appropriate for the specific project:
NR 110.09(1)(b)1.1. A description of the sewerage system for which construction drawings and specifications are to be prepared. This description shall include preliminary engineering data, cost estimates for design and construction of the sewerage system, and a schedule for completion of design and construction. The preliminary engineering data shall include, to the extent appropriate, information such as a schematic flow diagram, unit processes, design data regarding detention times, flow rates, sizing of units, and so forth. This is commonly referred to as the Unit Equipment and Design Report.
NR 110.09(1)(b)2.2. A description of the selected complete sewerage system of which the proposed facilities will be a part using maps, diagrams and plans as appropriate. This description shall include:
NR 110.09(1)(b)2.a.a. The delineation of a sewer service area for the complete sewerage system based on a 20-year population projection and density assumptions;
NR 110.09(1)(b)2.b.b. A description of the collection system including existing and proposed trunk sewers and interceptors;
NR 110.09(1)(b)2.c.c. A description of the existing and proposed sewerage treatment system including ultimate disposal of wastewater and sludge;
NR 110.09(1)(b)2.d.d. A planning area map showing individual systems, if individual systems are to be a part of the cost-effective solution proposed for state or EPA funding.
NR 110.09(1)(b)3.3. Infiltration/inflow documentation in accordance with subs. (5) and (6).
NR 110.09(1)(b)4.4. A cost-effectiveness analysis of alternatives for the sewerage system prepared in accordance with sub. (2). The most cost-effective alternatives shall be selected for implementation in accordance with s. NR 110.08 (6).
NR 110.09(1)(b)5.5. For facilities plans for state funded projects, parallel cost estimates shall be provided for the facilities necessary to transport and/or treat the fundable capacity, as well as a cost estimate for the total proposed sewerage system.
NR 110.09(1)(b)6.6. An identification of effluent discharge limitations including water quality related effluent limitations, and where a Wisconsin Pollution Discharge Elimination System (WPDES) permit has been issued, a copy of the permit for the proposed sewerage system.
NR 110.09(1)(b)7.7. Required comments or approvals of relevant state, interstate, regional, and local agencies.
NR 110.09(1)(b)8.8. An estimate of the anticipated cost to the average user of the system. This cost shall be presented at the public hearing required under sub. (4).
NR 110.09(1)(b)9.9. A brief summary of the public hearing required under sub. (4) or any other public meeting or hearing held during the planning process including a summary of the views expressed.
NR 110.09(1)(b)10.10. A brief statement demonstrating that the authorities who will be implementing the plan have the necessary legal, financial, institutional, and managerial resources available to insure the construction, operation, and maintenance of the proposed treatment works.
NR 110.09(1)(b)11.11. A description of potential opportunities for recreation, open space, and access to bodies of water analyzed in planning the proposed sewerage system and the recommended actions. The facility plan shall also describe measures taken to coordinate with federal, state and local recreational programs and with recreational elements of applicable approved areawide waste treatment management plans.
NR 110.09 NoteNote: Facilities plans for projects subject to the requirements of this section may include results from a system evaluation and capacity assurance plan under s. NR 110.10 (4).
NR 110.09(2)(2)Content of the cost-effectiveness analysis. The cost-effectiveness analysis shall include:
NR 110.09(2)(a)(a) The relationship of the size and capacity of alternative systems to the needs to be served, including reserve capacity;
NR 110.09(2)(b)(b) An evaluation of alternative flow and waste reduction measures, including non-structural methods;
NR 110.09(2)(c)(c) An evaluation of improved effluent quality attainable by upgrading the operation and maintenance and efficiency of existing facilities as an alternative or supplement to construction of new facilities;
NR 110.09(2)(d)(d) An evaluation of the capability of each alternative to meet secondary treatment standards or applicable water quality related effluent limitations. The sewerage system design must be based upon achievement of not less than secondary treatment standards as defined by ch. NR 210;
NR 110.09(2)(e)(e) An identification of and provision for applying technologies included under each of the following waste treatment management techniques:
NR 110.09(2)(e)1.1. Biological or physical-chemical treatment and discharge to receiving waters;
