NR 110.10(2)(b)3.b.b. Pressure to accelerate growth for quicker recovery of the nonfederal share of the interceptor investments. NR 110.10(2)(b)3.c.c. Effects on air quality and environmentally sensitive areas by cultural changes. NR 110.10(2)(b)4.4. Other nonmonetary impacts including implementation capability, operability, performance reliability and flexibility. NR 110.10(2)(c)(c) The estimation of peak flows in interceptors shall be based upon the following considerations: NR 110.10(2)(c)1.1. Daily and seasonal variations of pipe flows, the timing of flows from the various parts of the tributary area and pipe storage effects. NR 110.10(2)(c)3.3. The use of an appropriate peak flow factor that decreases as the average daily flow to be conveyed increases. NR 110.10(3)(3) Construction plans and specifications for sewer projects. In addition to the requirements of ch. NR 108 and ss. NR 110.06 and 110.07 plans and specifications for proposed sewer projects shall include a plan and profile view of all proposed construction. The plans and profiles shall show: NR 110.10(3)(a)(a) Location. The location of existing or proposed streets and sewers; NR 110.10(3)(b)(b) Streams and water surfaces. The location and 100 year flood elevation of all streams and water surfaces relevant to the project; NR 110.10(3)(c)(c) Elevations. The line of the ground surface, the invert and surface elevation at each manhole and the grade of the sewer between each adjacent manhole. Basement elevations shall be noted on the plans or the designing engineer shall state that all sewers are sufficiently deep to serve adjacent basements except where otherwise noted on the plans. Where gravity basement drainage to the proposed sewer will not be possible for existing buildings, the buildings’ owners shall be so advised prior to construction of the sewers; NR 110.10(3)(d)(d) Pipe size and material. The pipe size, material, pipe strength and bedding class shall be shown on the plans or in the specifications; NR 110.10(3)(e)(e) Manhole spacing. The length of sewer between the manholes shall be shown on the plans; NR 110.10(3)(f)(f) Special features. The locations of all special features including inverted siphons, concrete encasements, elevated sewers, and other features as appropriate; NR 110.10(3)(g)(g) Existing structures. The location of all known existing structures and utilities which might interfere with the proposed construction, particularly all water mains, gas mains, storm drains, and other pertinent structures; NR 110.10(3)(h)(h) Special drawings. Special detail drawings made to a scale to clearly show the nature of the design shall be furnished to show the following: NR 110.10(3)(h)1.1. Stream crossings with elevations of the stream bed and of normal and extreme high and low water levels; NR 110.10(3)(h)3.3. Details of all sewer appurtenances such as manholes, lampholes, inspection chambers, inverted siphons and elevated sewers. NR 110.10(4)(4) System evaluation and capacity assurance plan. A system evaluation and capacity assurance plan shall include all the following: NR 110.10(4)(a)(a) An evaluation of those portions of the sewage collection system that may contribute to sewage treatment facility overflows or other noncompliance at a sewage treatment facility, or that are experiencing or contributing to a sanitary sewer overflow caused by excessive infiltration and inflow or a system hydraulic deficiency. The evaluation must provide estimates of peak flows, including the amount from sanitary sewer overflows and sewage treatment facility overflows, provide estimates of the capacity of key system components, identify hydraulic deficiencies, and identify the sources (including private property sources) of infiltration and inflow that contribute to the peak flows associated with sanitary sewer overflow or sewage treatment facility overflow occurrences. NR 110.10(4)(b)(b) An analysis to identify actions that will eliminate sanitary sewer overflows and sewage treatment facility overflows or abate their occurrence and effects on public health and the environment to the extent technically and economically feasible. The analysis shall consider alternatives such as providing improved operation and maintenance, infiltration and inflow reduction, and removal from all sources, wastewater equalization or storage facilities, sewer and lift station replacement or rehabilitation, the treatment of overflows, peak flow treatment schemes at sewage treatment facilities, expansion of sewage treatment facility capacity, and any other construction of new or modified sewerage system components.
