Construction of new sanitary sewer lines will be required to service the project. The <br />projected wastewater flow rate for the site following construction is an average flow rate <br />of 88,800 gallons per day with a peak flow rate of 199,700 gallons per day. The City of Lino <br />Lakes and White Bear Township will execute an agreement for the utilization of a portion <br />of the capacity in the White Bear Township trunk sanitary sewer. The proposed residential <br />and retail land uses are expected to generate wastewater of typical domestic strength and <br />character. <br />The location of the Metro WWTP and existing interceptors are illustrated on Appendix A — <br />Figure 10. <br />2) If the wastewater discharge is to a subsurface sewage treatment systems (SSTS), <br />describe the system used, the design flow, and suitability of site conditions for such <br />a system. If septic systems are part of the project, describe the availability of septage <br />disposal options within the region to handle the ongoing amounts generated as a <br />result of the project. Consider the effects of current Minnesota climate trends and <br />anticipated changes in rainfall frequency, intensity and amount with this discussion. <br />N/A. Currently none of the parcels that comprise the project site utilize subsurface sewage <br />treatment systems (SSTS). Several of the adjacent properties currently utilize a SSTS. These <br />properties will be unaffected by the Project. <br />The locations of the adjacent properties with existing SSTS are illustrated on Appendix A — <br />Figure 10. <br />3) If the wastewater discharge is to surface water, identify the wastewater treatment <br />methods and identify discharge points and proposed effluent limitations to mitigate <br />impacts. Discuss any effects to surface or groundwater from wastewater discharges, <br />taking into consideration how current Minnesota climate trends and anticipated <br />climate change in the general location of the project may influence the effects. <br />N/A <br />ii. Stormwater - Describe changes in surface hydrology resulting from change of land cover. <br />Describe the routes and receiving water bodies for runoff from the project site (major <br />downstream water bodies as well as the immediate receiving waters). Discuss environmental <br />effects from stormwater discharges on receiving waters post construction including how the <br />project will affect runoff volume, discharge rate and change in pollutants. Consider the <br />effects of current Minnesota climate trends and anticipated changes in rainfall frequency, <br />intensity and amount with this discussion. For projects requiring NPDES/SDS Construction <br />Stormwater permit coverage, state the total number of acres that will be disturbed by the <br />project and describe the stormwater pollution prevention plan (SWPPP), including specific <br />best management practices to address soil erosion and sedimentation during and after <br />project construction. Discuss permanent Stormwater management plans, including methods <br />of achieving volume reduction to restore or maintain the natural hydrology of the site using <br />green infrastructure practices or other stormwater management practices. Identify any <br />receiving waters that have construction -related water impairments or are classified as special <br />as defined in the Construction Stormwater permit. Describe additional requirements for <br />special and/or impaired waters. <br />Page 16 <br />
