fifteen known concentration priority areas determined by the DNR to be relied upon to maintain the species’ security within the state. However, the DNR recommends that certain guidelines be followed during all construction activity in the area. The Red Shouldered Hawk, a special Concern Species, and a Uncas Skipper, an endangered butterfly, has also been observed within approximately 1 mile of the subject property. However, based upon the review by the Minnesota Department of Natural Resources, these elements are not likely to be impacted by the proposed project. A copy of the MNDNR review letter and the list of recommended measures for avoiding and minimizing impacts to Blandings Turtle are included as Attachment 1. 12. Physical impacts on water resources. Will the project involve the physical or hydrologic alteration — dredging, filling, stream diversion, outfall structure, diking, and impoundment — of any surface waters such as a lake, pond, wetland, stream or drainage ditch? __Yes X No If yes, identify water resource affected and give the DNR Protected Waters Inventory number(s) if the water resources affected are on the PWI: . Describe alternatives considered and proposed mitigation measures to minimize impacts. 13. Water use. Will the project involve installation or abandonment of any water wells, connection to or changes in any public water supply or appropriation of any ground or surface water (including dewatering)? __Yes X No If yes, as applicable, give location and purpose of any new wells; public supply affected, changes to be made, and water quantities to be used; the source, duration, quantity and purpose of any appropriations; and unique well numbers and DNR appropriation permit numbers, if known. Identify any existing and new wells on the site map. If there are no wells known on site, explain methodology used to determine. No new wells will be installed onsite. Material extracted from the expansion area will be conveyed to an aggregate processing area in the adjacent existing mining operation. The existing mining facility operates a washplant. The well associated with the washplant operates under DNR Water Appropriations Permit # 1991-3086. There is also a potable well located in the operations area which serves the scale building. The proposed additional mining area will not impact or require any changes to the existing permit. 14. Water-related land use management district. Does any part of the project involve a shoreland zoning district, a delineated 100-year flood plain, or a state or federally designated wild or scenic river land use district? __Yes X No If yes, identify the district and discuss project compatibility with district land use restrictions. The Flood Insurance Rate Map for Sherburne County indicates the site is not located within any delineated 100-year flood plain. The site does not fall within a shoreland zoning district or a state or a federally designated wild or scenic river land use district. 15. Water surface use. Will the project change the number or type of watercraft on any water body? __Yes X No If yes, indicate the current and projected watercraft usage and discuss any potential overcrowding or conflicts with other uses. 16. Erosion and sedimentation. Give the acreage to be graded or excavated and the cubic yards of soil to be moved: acres 20; cubic yards 400,000 cy net quantity of material to be removed. Describe any steep slopes or highly erodible soils and identify them on the site map. Describe any erosion and sedimentation control measures to be used during and after project construction. The on site soils are in general susceptible to erosion. Historically, they have been subjected to wind
