handle the ongoing amounts generated as a result of the project. Consider <br /> the effects of current Minnesota climate trends and anticipated changes in <br /> rainfall frequency, intensity, and amount with this discussion. <br /> Not applicable. <br /> 3) If the wastewater discharge is to surface water, identify the wastewater <br /> treatment methods and identify discharge points and proposed effluent <br /> limitations to mitigate impacts. Discuss any effects to surface or <br /> groundwater from wastewater discharges, taking into consideration how <br /> current Minnesota climate trends and anticipated climate change in the <br /> general location of the project may influence the effects. <br /> Not applicable. <br /> ii. Stormwater— Describe changes in surface hydrology resulting from change of <br /> land cover. Describe the routes and receiving water bodies for runoff from the <br /> project site (major downstream water bodies as well as the immediate receiving <br /> waters). Discuss environmental effects from stormwater discharges on receiving <br /> waters post-construction, including how the project will affect runoff volume, <br /> discharge rate, and change in pollutants. Consider the effects of current <br /> Minnesota climate trends and anticipated changes in rainfall frequency, <br /> intensity, and amount with this discussion. For projects requiring NPDES/SDS <br /> Construction Stormwater permit coverage, state the total number of acres that <br /> will be disturbed by the project and describe the stormwater pollution <br /> prevention plan (SWPPP), including specific best management practices to <br /> address soil erosion and sedimentation during and after project construction. <br /> Discuss permanent stormwater management plans, including methods of <br /> achieving volume reduction to restore or maintain the natural hydrology of the <br /> site using green infrastructure practices or other stormwater management <br /> practices. Identify any receiving waters that have construction-related water <br /> impairments or are classified as special as defined in the Construction <br /> Stormwater permit. Describe additional requirements for special and/or <br /> impaired waters. <br /> Prior to construction, stormwater runoff on the east of the site drains directly to the <br /> wetland on the east side of the property. Any drainage captured on the west side of <br /> the site by storm sewer is collected in a depression near the northwest entrance of <br /> the site, where the water infiltrates or overtops into swales along County Road 5. The <br /> proposed development includes five additional acres of impervious surface, <br /> increasing the runoff rate. After construction, water will be directed to one of four <br /> infiltration basins, where the water will then be directed to the same previous <br /> receiving water bodies. For ponds on the east side of the site, the eventual receiving <br /> water body will be the wetland that occupies the east side of the site. For ponds on <br /> the west side of the site, the outlet will tie into stormwater further south along <br /> County Road 5 and eventually make it to wetlands south of the site. <br /> A SWPPP will be developed for the project in accordance with the NPDES permit <br /> administered by the MPCA. The SWPPP will cover temporary measures to prevent <br /> Haviland Fields EAW 14 July 2023 <br />
