<br />Feasibility Study 112316 <br />City of Lino Lakes, Minnesota <br />NPDES Phase II Considerations <br />The National Pollutant Discharge Elimination System (NPDES) is the enforcement action taken by the <br />Environmental Pollution Agency (EPA) to meet the Clean Water Act. Phase II of this program is directed <br />towards cities with populations greater than 10,000 or cities with impaired or special water such as the <br />Mississippi River. <br />Lino Lakes is a mandatory Municipal Separate Storm Sewer System (MS4) and currently has a permit that is <br />governed by the City’s Storm Water Pollution Prevention Plan (SWPPP). For the storm water budget, a figure <br />of $10,000 per year has been included to address the planned activities. <br />The Storm Water Utility Utilizes: <br />• The “Residential Equivalent Unit” (REU). The REU is the “billing unit” that represents the <br />residential, single-family homes, which make up approximately 90% of Lino Lakes current billing. <br />The REU is easily understood and facilitates billing by allowing the billing department to enter in one <br />value (the REU) for all homes vs. nearly 6,000 individual bills that may differ by only a few cents. <br />The suggested REU for Lino Lakes residential units would be $2.50 per month ($30/year) per <br />address. <br />• Intensity of Development (Land Use). As the intensity of development increases, so does the amount <br />of impervious surfaces, leading to more runoff. <br />• Equivalent Hydrologic Area (Curve number) This engineering methodology is used to measure the <br />amount of impervious surface and is utilized in calculating the amount each property should pay <br />based upon “contributors pay”. <br />• Program budget. What are the anticipated costs? What must you do? What do you want to do? Below <br />is the estimated Storm Water Budgets for years 2011 through 2015. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
