Black Creek 2030 Sewer Service Area WDNR Approval March 14, 2008
Required by the State of Wisconsin (Wisconsin administrative Code, NR 121), Area wide Water Quality Management Plans (AWQMP) oversee, protect, and enhance groundwater and surface water quahty. The AWQMP serves to umbrella subsequent water quality initiatives and activities affecting water quality and uses, including point and nonpoint pollutant sources and related environmental resource considerations. One item found under the umbrella of Areawide Water Quality Management Planning is the Sewer Service Area Plan.
A Sewer Service Area Plan (SSAP) protects water quality by proactively addressing the future needs for wastewater collection and treatment in developing areas. This planning helps protect water resources from adverse impacts associated with development by implementing cost-effective and environmentally sound 20-year sewerage system growth plans. An SSAP identifies existing sewered areas as well as available land suitable for new development. The planning process also identifies areas not amenable for sewerage, including but not limited to environmentally sensitive areas (NR 121.05(l)(g)2.c).
Goals to establish guidance for service area planning, policies relating to wastewater cohection and treatment within the City of Superior were developed in tandem with the Comprehensive Plan. City policies framing service area planning decisions include:
• Providing cost-effective collection and treatment facilities;
• Consideration of current and anticipated development or redevelopment that conforms with the Land Use Element of the Comprehensive Plan;
• Providing collection and treatment infrastructure improvement and upgrades accommodating 7-yr design events, and addressing NPDES permitting and EPA
• Providing collection and treatment facihties that comply with state and federal regulations and Special Area Management Plan (SAMP) guidance regarding wetlands;
• Optimizing Main and CSO treatment plant performance and efficiency;
• Emphasize and optimize industrial pretreatment and pollution prevention strategies;
• Emphasize interagency cooperation and public involvement in a professional manner with openness, honesty and integrity.
With input from Planning, Engineering, and Wastewater, and WDNR personnel the SSAP effectuates long-term water quality protection by designating as environmentally sensitive wetlands, shorelands, floodplains, steep slopes, lands with erodible soils, and environmentahy limiting areas within the planning area boundary. Additional areas within the City's limits which are guarded from sewered development include parks, the municipal forest and other valuable recreational areas. Limiting growth in those areas mentioned above safeguards pubhc and environmental health, protects diverse aquatic wildlife, and provides continued benefits associated with enjoyed recreational areas.
