NR 110.09(3)(b)(b) Description of the future environment without the project. The future environmental conditions with the no project alternative shall be forecast, covering the same areas listed in par. (a).
NR 110.09(3)(c)(c) Evaluation of alternatives. This discussion shall include a comparative analysis of feasible options and a systematic development of wastewater treatment alternatives. The alternatives shall be screened with respect to capital and operating costs; significant primary and secondary environmental effects; physical, legal or institutional constraints; and whether or not they meet regulatory requirements. Special and induced impacts such as development. The reasons for rejecting any alternatives shall be presented in addition to any significant environmental benefits precluded by rejection of an alternative. The analysis should consider, when relevant to the project:
NR 110.09(3)(c)1.1. Flow and waste reduction measures, including infiltration/inflow reduction;
NR 110.09(3)(c)2.2. Alternative locations, capacities, and construction phasing of facilities;
NR 110.09(3)(c)3.3. Alternative waste management techniques, including treatment and discharge, wastewater reuse and land application;
NR 110.09(3)(c)4.4. Alternative methods for disposal of sludge and other residual waste, including process options and final disposal options;
NR 110.09(3)(c)5.5. Improving effluent quality through more efficient operation and maintenance;
NR 110.09(3)(d)(d) Environmental impacts of the proposed action. Primary and secondary impacts of the proposed action shall be described, giving special attention to unavoidable impacts, steps to mitigate adverse impacts, any irreversible or irretrievable commitments of resources to the project and the relationship between local short term uses of the environment and the maintenance and enhancement of long term productivity. The significance of land use impacts shall be evaluated, based on current population of the planning area; design year population for the service area; percentage of the service area currently vacant; and plans for staging facilities. Special attention should be given to induced changes in population patterns and growth, particularly if a project involves some degree of regionalization.
NR 110.09(3)(e)(e) Steps to minimize adverse effects. This section shall describe structural and nonstructural measures, if any, in the facilities plan to mitigate or eliminate significant adverse effects on the human and natural environments. Structural provisions include but are not limited to changes in facility design, size, and location; nonstructural provisions include but are not limited to staging facilities as well as developing and enforcing land use regulations and environmentally protective regulations.
NR 110.09(3)(f)(f) Documentation. Sources of information used to describe the existing environment and to assess future environmental impacts should be documented. In addition to the department, these sources should include regional, state and federal agencies with responsibility or interest in the types of impacts listed in par. (a). In particular, the following agencies should be consulted:
NR 110.09(3)(f)1.1. Local, and regional land use planning agencies and areawide waste treatment management planning agencies for assessments of land use trends and population projections, especially those affecting size, timing, and location of facilities;
NR 110.09(3)(f)2.2. The HUD regional office if a project involves a flood risk area identified under the Flood Disaster Protection Act of 1973 (Pub.
NR 110.09(3)(f)2.L.L. 93-234);
NR 110.09(3)(f)3.3. The state coastal zone management agency, if a coastal zone is affected;
NR 110.09(3)(f)4.4. The secretary of the interior or secretary of agriculture, if a wild and scenic river is affected;
NR 110.09(3)(f)5.5. The secretary of the interior or secretary of commerce, if a threatened or endangered species is affected;
NR 110.09(3)(f)6.6. The fish and wildlife service (department of the interior), the department of commerce, and the U.S. army corps of engineers, if a wetland is affected.
NR 110.09(4)(4)Public hearing. Municipalities shall hold at least one public hearing before a facilities plan is adopted. A copy of the facilities plan should be available for public review before the hearing and at the hearing, since these hearings provide an opportunity for public comment on the issues associated with the facilities plan.
NR 110.09(5)(5)Content of an infiltration/inflow analysis.
NR 110.09(5)(a)(a) The infiltration/inflow analysis shall demonstrate whether or not excess infiltration/inflow exists in the sewer system. The analysis shall identify the presence, flow rate, and type of infiltration/inflow conditions, which exist in the sewer systems.
NR 110.09(5)(b)(b) For determination of the possible existence of excessive infiltration/inflow, the analysis shall include an estimate of the cost of eliminating the infiltration/inflow conditions. These costs shall be compared with estimated total costs for transportation and treatment of the infiltration/inflow. This determination shall be made at several levels of infiltration/inflow removal.
NR 110.09(5)(c)(c) If the infiltration/inflow analysis demonstrates the existence or possible existence of excessive infiltration/inflow and the specific sources of excessive infiltration/inflow have not been adequately identified, a sewer system evaluation survey shall be conducted in accordance with sub. (6). A detailed plan for the sewer system evaluation survey shall be included in the infiltration/inflow analysis. The plan shall outline the tasks to be performed in the survey and their estimated costs.
NR 110.09(5)(d)(d) The department may waive the requirements of pars. (a) through (c) if the owner can demonstrate to the department’s satisfaction the obvious existence or nonexistence of excessive infiltration or inflow, or both. The information necessary for this demonstration may include infiltration and inflow estimates, per capita design flows, ratio of total flow to dry weather flow, cubic meters of infiltration per centimeter diameter per kilometer of pipe per day (gallons of infiltration per inch diameter per mile per day), bypassing, and other hydrological and geological factors. The department may require the information be expanded to meet the requirements of pars. (a) through (c) if this demonstration is inconclusive.
NR 110.09(6)(6)Content of a sewer system evaluation survey.
NR 110.09(6)(a)(a) The sewer system evaluation survey shall determine the location, estimated flow rate, method of rehabilitation and cost of rehabilitation versus cost of transportation and treatment for each defined source of infiltration/inflow.
NR 110.09(6)(b)(b) The report shall summarize the results of the sewer system evaluation survey. In addition, the report shall include:
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.
