Response to Draft Scoping EAW Comments January 9, 2018 Page 11 c) Because the Mississippi River is classified as a special water, soils will need to be stabilized within seven days of temporarily or permanently ceasing soil disturbing activity on any portion of the Project site. In addition, an undisturbed 100-foot buffer zone must be maintained between the river and the Project unless an encroachment is necessary to complete the Project and the area will be restored. d) The wetlands located at the site cannot be utilized for stormwater management or treatment unless they have gone through the mitigation process. e) The CSW Permit requires that one inch of stormwater runoff from new impervious surfaces is retained on the Project site via infiltration or other volume reduction method and not discharged to a surface water unless prohibited due to a high seasonal water table or bedrock. f) Assuming 50 or more acres will be disturbed as a result of the Project, the Stormwater Pollution Prevention Plan must be submitted to the MPCA for review at least 30 days prior to applying for permit coverage even if only a smaller portion of the Project site will be constructed at one time. • Please include Diamond Lake under Water Resources, part (a.,i.) (pg. 11). Diamond Lake (27-0125) is on the MPCA 303d Impaired Waters List and is impaired by nutrients. This lake appears to be within one mile of the Project site. Resaonse: These items will be included and assessed in the AUAR. NATIONAL PARK SERVICE COMMENTS 1) The northern portion of the proposed project would lie within the boundary of the Mississippi National River and Recreation Area`(NRRA). Congress established the Mississippi NRRA in 1988 to preserve, protect, and enhance the significant values of the Mississippi River Corridor in the Twin Cities metropolitan area. Response: The location of the NRRA will be noted in the AUAR. 2) Under Item 9a the document states only that "the northern portion of the site is located within the Mississippi River Corridor Critical Area Program district CA -SR..." The Mississippi River Corridor Critical Area (MRCCA) shares the same boundary as the Mississippi NRRA. The Minnesota Department of Natural Resources (DNR) administers the MRCCA program allowing for cooperative management of the Mississippi NRRA with local governments including the City of Dayton. A notation should be made that this area is also part of the Mississippi NRRA. Resaonse: This correction will be made in the AUAR. 12800 Whitewater Drive, Suite 300, Minnetonka, MN 55343 1763.476.6010 2401 46th Avenue Southeast, Suite 202, Mandan, ND 58554 1701.204.6845 www.sambatek.com
