NR 110.09(6)(b)1.1. A justification for each sewer section cleaned and internally inspected; and NR 110.09(6)(b)2.2. A proposed rehabilitation program for the sewer system to eliminate all defined excessive infiltration/inflow. NR 110.09(7)(7) Construction plans and specifications for sewage treatment plant projects. In addition to the requirements of ch. NR 108 and ss. NR 110.06 and 110.07, the following requirements shall be adhered to for submission of plans for sewage treatment plants. NR 110.09(7)(a)(a) Overall plan. A plan shall be submitted which shows the sewage treatment plant in relation to the remainder of the system. Sufficient topographic features shall be included to indicate its location with respect to streams and the point of discharge of treated effluent. NR 110.09(7)(b)(b) Layout. A general layout plan shall be submitted which includes: NR 110.09(7)(b)4.4. Piping details including piping arrangements for bypassing individual units; NR 110.09(7)(b)5.5. The materials handled and the direction of flow through each pipe; NR 110.09(7)(c)(c) Detailed plans. Detailed construction plans shall be submitted which include: NR 110.09(7)(c)1.1. The location, dimensions, elevations and details of all existing and proposed plant units; NR 110.09(7)(c)2.2. The elevation of high and low water level in the receiving stream; NR 110.09(7)(c)3.3. An adequate description of all features not covered in the specifications. NR 110.09(8)(8) Additional facility planning requirements for land disposal system alternatives. NR 110.09(8)(a)(a) General requirements. In addition to the requirements of sub. (1), a report including a soil investigation and a hydrogeologic evaluation shall be submitted as part of the facilities plan for a land disposal discharge alternative. The report shall detail the soil types, characteristics, variability and permeability, topography, groundwater conditions and quality, and other characteristics of the disposal site. Soil boring and test pit logs and soil analyses shall be provided. Wastewater characteristics which may influence the design of the disposal system shall also be discussed. Water supply quality, local groundwater use, and potential impacts of the facility on groundwater quality shall be included. NR 110.09(8)(b)1.1. A hydrogeological investigation shall be included as part of the facilities plan. The analysis of the hydrogeological information shall be done by a hydrogeologist, or other qualified person. The investigation shall include both regional and site-specific hydrogeological information. NR 110.09 NoteNote: The skills and knowledge required of a hydrogeologist making submittals under this chapter include: the ability to apply hydrogeologic principles and practices to the siting, design and operation of land disposal systems; knowledge of contaminants associated with land disposal of wastewater, their transport mechanisms and fate in the environment; familiarity standards; and proficiency in the design of groundwater monitoring systems for defining the physical and chemical characteristics of groundwater flow. A soil scientist or other environmental scientist who can demonstrate the above skills and knowledge, as reflected in submittals made under this chapter, shall be deemed a “qualified person”.
NR 110.09(8)(b)2.2. The following site-specific groundwater information may be required as part of the facilities plan for land disposal facilities:
