to promote retention of stormwater on the site while also providing other environmental benefits. Response: Low Impact Development strategies will be used to the extent practicable. The PUD process allows for flexibility in pavement widths and requires higher levels of open space than conventional development. A stormwater reuse system for irrigation will be evaluated as part of the development review process and used where possible. During construction, the MPCA National Pollutant Discharge Elimination System/State Disposal System (NPDES/SDS) Construction Stormwater Permit (CSW Permit) requires preservation of the existing 50 feet of natural buffer to wetlands on the site. If the existing buffer must be encroached to complete the construction, then redundant (double) down gradient sediment controls must be utilized to protect the wetlands. Questions regarding Construction Stormwater Permit requirements should be directed to Roberta Getman at 507-206-2629 or Roberta.Getman@state.mn.us. Response: The project proposer will be designing the stormwater basins and on -site floodplain mitigation in accordance with the City and Rice Creek Watershed District requirements to account for flood risk on site. The development will obtain an NPDES/SDS CSW permit and follow the wetland buffer requirements around preserved wetlands on site. Contamination/Hazardous Materials/Wastes (Item 12) Comment: Please be aware that farmsteads have the potential for releases or threatened releases of agricultural chemicals. The Minnesota Department of Agriculture (MDA) is the regulatory agency charged with managing the response and cleanup of fertilizers and pesticides. Information regarding the MDA is available on the website at: https://www.mda.state.mn.us/pesticide-fertilizer/spills-cleanup. For questions regarding agricultural chemicals, please contact Cathy Villas -Horns with the MDA at 651-201-6697. For questions regarding waste pesticide containers, please contact Jane Boerboom with the MDA at 651-201-6540. Response: As part of the EAW process, the MDA's What's In My Neighborhood was reviewed as part of Item 12 — Contaminated/Hazardous Materials and did not indicate that there are any known and potential sources of agriculture chemical soil and ground water contamination on site. Additionally, a Phase I Environmental Assessment was completed as part of the developer's due diligence of the site. Other Potential Environmental Effects (item 20) Comment: Please note that chloride (salt) is a growing issue for lakes, streams, and groundwater around the state. Chloride can come from both de-icing salt and water softener salt. For the proposed Project, the MPCA recommends smart salting practices for de-icing streets and driveways during the winter weather months and water softening best practices be 2
