Record of Decision — Riverstone South Environmental Assessment Worksheet Response Comments regarding permitting requirements are noted. Stormwater from impervious surfaces will be treated in the stormwater pond located west of lake before flowing to the lake. This stormwater pond is sized to handle and treat this runoff prior to discharging to the lake. The only direct flow to the lake will be from the rear yards adjacent to the lake. The stormwater pond will also treat stormwater prior to infiltration. project proponent and the City of Ramsey are reviewing the potential to reuse stormwater for irrigation. Noise The MPCA appreciates the proposer's attention to construction and other noise for the Project. At this time, the MPCA feels that the considerations made by the Project proposer are sufficient, and that it is unlikely that there will be noise issues if the mitigation measures described on p. 29 of the EAW are included in the final site plans and buildout. Response Comment noted. Minnesota State Historic Preservation Office Historic Properties We conclude that there are no properties listed in the National or State Registers of Historic Places and no known or suspected archaeological properties in the area that will be affected by this project. Response Comment noted. Minnesota Department of Natural Resources Stormwater Consider using water from the "lake" for irrigating landscaping in the development. The use of water from a constructed stormwater facility (not previously a wetland, stream, or lake) is exempt from the need for a DNR Water Appropriation Permit. Increased impervious surface will lead to increased road salt use in the project area. Consider promoting local business and city applicator participation in the Smart Salting Training offered through the Minnesota Pollution Control Agency. Winter maintenance staff who have attended the Smart Salting training have used their knowledge to reduce salt use and save money for their organizations. Response The project proponent and the City of Ramsey are reviewing the potential to reuse stormwater from the "lake" for irrigation. The City is reviewing and will consider implementing educational and long-term chloride from the Twin Cities Metropolitan Area Chloride Management Plan (https://www.pca.state.mn.us/sites/default/files/wq- iwl 1-06ff.pdfl. Educational programs such as the Smart Salting Training can be made available to private contractors as well as City staff. Accordingly, chloride reduction strategies will be considered to the extent practicable. 4
