Shoreview Comprehensive Plan The City's storm water management system is funded with this utility, including storm sewer and storm water ponds (Map 9D-6). Impaired Waters The City does have five water bodies that appear on the 2008 MPCA Final Draft list of impaired waters.. ,which are listed below: • Rice Creek (Aquatic Macroinvertebrate and Fish bioassessments) • Island Lake (NutrienbEutrophication/Biologic indicators) • Turtle Lake (Mercury in fish tissue) • Snail Lake (Mercury in fish tissue) • Lake Owasso (Mercury in fish tissue) Two of these, Snail and Owasso, are included in the Statewide Mercury Total Maximum Daily Load (TMDL) study, which was approved by the United States Environmental Protection Agency in 2007. This study identifies that deposition of mercury from the atmosphere is the principal component of the mercury concentration in game fish. No local point or non-point sources of mercury were identified in Shoreview and no City action is required. At this time a Total Maximum Daily Load (TMDL) has not been established for the other three impaired waters located within the City. Once MPCA funding is allocated the WMO where is the impaired water is located will act as the LGU and initiate the study, and so for each of the three impaired waters within the City, the RCWD will be responsible for the study. The City of Shoreview will work with the RCWD in an advisory role in the development of the study and establishment of the TMDL. After the study is complete and a TMDL has been established the City will review the SWPPP to determine if it is adequate to meet the TMDL's Waste Load Allocations. If the SWPPP is not meeting the applicable requirements, schedules, and objectives of the established TMDL, the SWPPP will be modified as appropriate. Although TMDL limits have not been established for the impaired waters within Shoreview's boundary the City will review the existing SWPPP to determine if modifications can be made to reduce the impact of our storm water discharge. Goals, Policies and lZecoended Actions The City will rely on the SWMP as the primary mechanism for managing surface water resources. The SWMP establishes the following Goals. Water Quality -Maintain or improve water quality to meet established standards consistent with the intended use and classification, with special focus on Category I water bodies. 2. Water Quantity (Flooding) -Control flooding and protect property while minimizing public expenditures necessary to control volumes and rates of runoff Surface Water Management Page 9.D-6
