(1) FACILITIES
				PLANS FOR SEWAGE TREATMENT FACILITIES PROJECTS.
(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.
(b) Facilities
				planning shall include the following information in such detail as the
				department deems appropriate for the specific project:
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.
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:
a. The delineation of a sewer
				service area for the complete sewerage system based on a 20-year population
				projection and density assumptions;
b. A description of the collection system
				including existing and proposed trunk sewers and interceptors;
c. A description of the existing and proposed
				sewerage treatment system including ultimate disposal of wastewater and
				sludge;
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.
3. Infiltration/inflow documentation in
				accordance with subs. (5) and (6).
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).
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.
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.
7. Required comments or approvals of relevant
				state, interstate, regional, and local agencies.
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).
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.
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.
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.
Note:
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).
