operation which allows excavation and processing during both daytime and nighttime hours as defined by the MPCA. An analysis of noise impacts from the proposed mining was performed by David Braslau Associates, Inc. The purpose of the analysis was to predict noise levels as mining and processing activities progress through the proposed mining area and identify measures needed in order to meet daytime and nighttime noise standards at the nearest receptors. As part of the analysis, noise levels were monitored at the existing operation and were found to be within daytime standards. Predictions were made based on an analysis of existing topography, proposed grade changes, and distance to the nearest receptors. The analysis found that with the construction of a ten foot high berm within the setback area along Proctor Avenue, the mining and processing activity will be sufficiently shielded to meet the nighttime noise standard. Tiller Corporation will conduct follow-up noise monitoring to demonstrate compliance with state noise standards. In addition, Tiller will be fitting their equipment with strobe light back-up alarms for non-daylight hours and during daylight hours a new back-up alarm recently approved by OSHA and MSHA will be used. The new alarm is a broadband sound back-up alarm that operates at a broader range frequency as opposed to the traditional narrow band backup alarms, characterized by the high pitched beep. The broad range frequency blends into background noise frequencies so that it becomes considerably less distinguishable with distance from the source. 25. Nearby resources. Are any of the following resources on or in proximity to the site? Archaeological, historical or architectural resources? __Yes _X_No Prime or unique farmlands or land within an agricultural preserve? __Yes _X_No Designated parks, recreation areas or trails? _X_Yes __No Scenic views and vistas? __Yes _X_No Other unique resources? __Yes _X_No If yes, describe the resource and identify any project-related impacts on the resource. Describe any measures to minimize or avoid adverse impacts. The site is located near a city park that contains a documented oak forest native plant community. The City is also acquiring the southern portion of the subject parcel to include within their existing Park system. The State Historical Preservation Office was asked to conduct a search of their cultural resources database. No archaeological sites or historic structures were identified in a search of the Minnesota Archaeological Inventory and Historic Structures Inventory for the search area requested. 26. Visual impacts. Will the project create adverse visual impacts during construction or operation? Such as glare from intense lights, lights visible in wilderness areas and large visible plumes from cooling towers or exhaust stacks? __Yes _X_No If yes, explain. 27. Compatibility with plans and land use regulations. Is the project subject to an adopted local comprehensive plan, land use plan or regulation, or other applicable land use, water, or resource management plan of a local, regional, state or federal agency? _X_Yes __No. If yes, describe the plan, discuss its compatibility with the project and explain how any conflicts will be resolved. If no, explain. The proposed project is compatible with local land use plans and regulations. The proposed project is located within the City of Elk River and subject to the City’s Comprehensive Land Use Plan. The future land use map for the City of Elk River designates the area of the proposed project to be mining. The City’s zoning regulations would require that the parcel of property to be mined be rezoned to a Mineral Excavation Overlay. 28. Impact on infrastructure and public services. Will new or expanded utilities, roads, other
