31. Summary of Issues: Do not complete this section if the E~4 }V is being done for EIS scoping; instead, address relevant issues in the draft Scoping Decision document, which must accompany the E~4 ~. List any impacts and issues identified above that may require further investigation before the project is begun. Discuss any alternatives or mitigative measures that have been or may be considered for these impacts and issues, including those that have been or may be ordered as permit conditions. Environmental issues that have been identified for the proposed project include the following: noise, dust, traffic, air quality, potential surface water impacts, potential groundwater impacts, potential rare species disturbances, and potential affect on prime or unique farmlands. The City of Elk River will address these issues through the Conditional Use Permit and Excavation License process, including annual review. Noise and visual impacts have been addressed by designating allowable hours of operation. No intense lighting will be used at the Site. The physical setting of the project site (surrounded to north, south, and west by mining) conforms to the surrounding land · use and therefore reduces these potential impacts. The specific hours of operation will be determined as part of the Conditional Use Permit. Potential dust generation has been addressed by requiring dust control on an as needed basis. Completed mining areas and soil stockpiles are to be seeded to stabilize soil and minimize wind blown dust particulates. Paving of a portion of the site entrance/exit road will also be considered to reduce dust. The affect of the proposed project on traffic is not anticipated to be .of concern due to the project location. Potential traffic issues have been addressed by the MnDOT requirements of constructing auxiliary northbound and southbound shoulder lanes on Trunk Highway 169 between 217th Avenue and 219th Avenue. All drivers will be instructed to travel in the auxiliary lanes only. Truck traffic generated by the gravel mine will be limited to the approximate 1,000 foot stretch between 219th Avenue and 217th Avenue on Trunk Highway 169 only. Odors from the asphalt plant will be controlled and minimized by engineering and designing the appropriate stack height for the operation. The use of recycled asphalt in the plant operation will also be limited, thus reducing some of the nuisance odors. Hours of plant operation will be adjusted as needed based on weather conditions and/or periods of inversion. Potential to emit calculations will be performed for the gravel mining operation and portable asphalt plant and the need for an air quality permit will be assessed at that time. Permits will be obtained from the MPCA. It is not anticipated that the proposed project will not adversely affect air quality in the surrounding area. Surface water, erosion, and sedimentation have been reviewed and mitigative measures have been proposed to control these issues. The proposed project does not encounter or alter drainage into the wetlands located on the Site, or contribute directly into other surface water bodies. Adherence to NPDES requirements is also required. Physical controls to be implemented during the proposed operation include adherence to a grading L1ESCH ASSOCIATES, INC.
