Sand and Reviewed by Gravel Mines Environmental Assessment Cal Portner, City Administrator Worksheet Action Requested Adopt,by resolution, a negative declaration on the need for an Environmental Impact Statement (EIS) for Tiller Corporation and Max Stemiger Inc. Sand and Gravel Mines Environmental Assessment Worksheet (EAW). Background/Discussion The purpose of the EAW is to describe the project and gather information to identify any potential environmental impacts. Staff believes the EAW accurately describes the project and any potential environmental impacts. Mitigation measures to reduce the environmental impacts have been identified by the EAW and will be incorporated into the project plans. Staff recommends a negative declaration on the need for an EIS for the Tiller Corporation and Max Steininger,Inc. request. The Elk River City Council is the Responsible Governmental Unit (RGU) charged with determining, from the information gathered through the EAW process,whether or not this project has significant potential to cause irreversible environmental impacts. If the Council believes there is a significant potential to cause irreversible environmental impacts, they shall order the preparation of an Environmental Impact Statement (EIS) for the project. The Council will consider the following information: the EAW, comments received on the EAW, and the responses to the comments received. The Council shall order the preparation of an EIS if they determine the impacts may reasonably be expected by the project to have the potential for significant environmental impacts. The Council shall consider the impacts of the project under the following criteria: ■ The type, extent, and reversibility of the environmental effects. ■ Cumulative Potential Effects. The RGU shall consider the following factors: Whether the cumulative potential effect is significant;whether the contribution from the project is significant when viewed in connection with other contributions to the cumulative potential effect; the degree to which the project complies with approved mitigation measures specifically designed to address the cumulative potential effect; and the efforts of the proposer to minimize the contributions from the project. ■ The extent to which the environmental effects are subject to mitigation by ongoing public regulatory authority. The RGU may rely only on mitigation measures that are specific and can be reasonably expected to effectively mitigate the identified environmental impacts of the POWERED 6T A IR project. ■ The extent to which environmental effects can be anticipated and controlled as a result of other available environmental studies undertaken by public agencies or the project proposer,including other EISs. The EAW was noticed to agencies by the Environmental Quality Board on September 12, 2016. Few comments were received by October 12, the end of the 30-day comment period.

Provide the brief project summary to be published in the EQB Monitor, (approximately 50 words). Tiller Corporation and Max Steininger, Inc. (Proposers) control adjacent properties located in Elk River, MN (Site or Project Area). The entire Project Area encompasses 142 acres. The Proposers are seeking to amend the zoning to include mineral extraction overlay and to permit the properties under two separate conditional use permits to allow for coordinated sand and gravel mining operations (Project). Site operations will include stripping, extraction, processing, recycling of concrete and asphalt and comprehensive site reclamation. b. Give a complete description of the proposed project and related new construction, including infrastructure needs. If the project is an expansion include a description of the existing facility. Emphasize: 1) construction, operation methods and features that will cause physical manipulation of the environment or will produce wastes, 2) modifications to existing equipment or industrial processes, 3) significant demolition, removal or remodeling of existing structures, and 4)timing and duration of construction activities. The Project involves the establishment of two separate sand and gravel mining operations on adjacent properties located in the very northern portion of Elk River. Max Steininger, Inc. owns 61.7 acres of land in the northern half of the project area (PIDs: 751031101 and 7578020105) and Tiller Corporation has a purchase agreement on 62.6 acres (PIDs: 751031300 and a portion of 751031400). An additional 18+/- acres which includes Baldwin Street and areas east of Baldwin Street (PIDs: 751031105 and 751031400) are also likely to be mined in order to accommodate the lowering of the roadway as well as achieving reclamation grades better suited to future development. The mining extent on the additional property will be limited to the elevation of approximately 980 feet msl. Mining depths may be lower than 980 feet msl and the area will be reclaimed to an appropriate elevation needed to achieve the final road alignment. The eastern parcel of the Tiller property includes a total of 69 acres, 7.3 acres are located west of Baldwin Street and 62 acres are located east and southeast of Baldwin Street.The Project will require a lot split to create two separate parcels on either side of Baldwin Street. Only the 7.3 acre parcel located west of Baldwin is included in the Project Area. Figure 1: General Location Map, illustrates the location of the Site with respect to Sherburne County. Figure 2: USGS Quad Map Excerpt, shows the topography and natural features of the Site and surrounding area. Figure 3: Parcel Map, illustrates the ownership and acreage of the individual parcels described above. The Site is zoned CRT, Commercial Reserve Transition, and will require a zone change and amendment to the City Zoning Map to include a mineral excavation overlay zoning district over the Project Area. The purpose of the mineral excavation overlay zoning district is to provide a specific zoning district for the establishment of sand and gravel mining operations. The Site meets all criteria for the zone change. The current mineral extraction overlay district extends to the southern boundary of the Project Area as well as to the southwest across US 169. Environmental Assessment Worksheet Page 3 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. Mineral excavation operations and related facilities are a conditional use within the mineral excavation overlay district. Two separate Conditional Use Permits (CUP) will be requested, one for the Steininger property and one for the Tiller property. The Project will allow the mining and processing of a high quality deposit of sand and gravel that will be processed for use as construction aggregates to serve the growing demand within the local area and the City of Elk River. The Site is surrounded by several other mining operations and is located adjacent to the Elk River Mining District Environmental Impact Statement (Elk River EIS) study area. Although not included in the study area, much of the information gathered in the study is relevant to the Site. Active mining will begin by stripping topsoil and overburden from the Site using scrapers, excavators, off-road trucks and dozers. Overburden and topsoil will be shaped into perimeter berms. Extraction of the aggregate deposit will be accomplished with loaders and excavators. Mining will extend into the water table. Processing will include crushing, screening, and washing. Recycled concrete and asphalt will be processed at the Site. Equipment and screening berms will be placed to insure compliance with both daytime and nighttime noise standards. Reclamation will include backfilling, sloping and establishment of grades which accommodate the final land use of the Site. Some of the materials used for backfilling may include clean fill imported from construction sites. The Proposer's will work with each other and adjacent mining operators to the north and south of the Site to mine and reclaim common mining borders. Baldwin St. NW may also be lowered in the future in coordination with adjacent mining operations. There will be minimal amounts of solid waste generated by the Project. There is an existing residence, garage and outbuildings, located on the northeast parcel of the Site which will eventually be removed, creating a minimal amount of demolition debris. If Baldwin St NW is lowered, an additional out building located east of the road will also be demolished. All demolition waste generated from removal of these existing structures will be hauled to a licensed disposal facility. No permanent structures will be constructed on-site. The Project (including both proposed mining sites) is estimated to last 30 years or more. Vertical road profiles adjacent to mined areas were one of the main transportation issues studied in the Elk River EIS. The City recognized that leaving existing roads at their original elevations would prohibit future development by making them inaccessible from adjacent property and create potential for structural instability caused by erosion. The Elk River EIS concluded that the roads should be lowered along with the surrounding property. As mining has progressed through the gravel mining district, roads have been realigned and their vertical profiles lowered, consistent with the mined areas reclamation grades. Examples include portions of 221ST Ave NW, and County Roads 77 and 33. It is likely that Proctor Road NW and 213th Ave NW will be lowered in the future. Environmental Assessment Worksheet Page 4 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. Recognizing that there are sand and gravel mining operations to the south the north of the Project, Baldwin Ave NW and possibly 225th Street Ave NW (located south of the Site, within the Knife River mine site), should also be lowered to be conducive to future land use. Lowering the vertical alignment will require coordination with the adjacent property owners. For the purposes of this EAW the Project only considers lowering that portion of Baldwin St NW that lies adjacent to the Project boundaries.The realignment is assumed to begin north of the residential property that is located southeast of the Project and southeast of Baldwin St NW. The lowering would continue to the northern property line of the Site. It is assumed that coordination with the Toth mine would result in lowering of the alignment to the north into Lavonia Township where Baldwin Ave NW turns into 112th Street NW. In order to accommodate grading for the vertical realignment, one agricultural outbuilding would be required to be removed east of Baldwin Ave NW. Based on information from the National Wetland Inventory, grading limits to the east would not encroach on any existing wetland basins. Erosion and sedimentation control measures and best management practices required for construction projects would be implemented. No direct or indirect impacts to wetlands are anticipated as discussed in a subsequent section of this EAW. c.

Explain the project purpose; if the project will be carried out by a governmental unit, explain the need for the project and identify its beneficiaries. The purpose of the Project is to provide aggregate material for use in various construction materials and projects throughout the northwestern metropolitan area. The aggregate produced at the Site will be used for roads and buildings in both the public and private sectors. Aggregate from the Site may be used in the production of bituminous asphalt and ready-mix concrete, aggregate base, general fill and ice control. e.

Land use: a. Describe: i. Existing land use of the site as well as areas adjacent to and near the site, including parks,trails, prime or unique farmlands. Existing land use of the Site is open space with one single family residence located in the northeastern portion of the Site. Land use surrounding the Site is predominantly permitted sand and gravel mining operations. There are three permitted mines to the north of the Site (Plaisted, Toth, and Manthei), one permitted mine to the south of the Site (Knife River which includes operation of a portable asphalt plant), two permitted mines located across TH 169 to the southwest of the Site (Tiller which includes an asphalt plant and C.S. McCrossan) and one permitted mine to the northwest of the Site (Tiller). Other adjacent land uses include the Elk River Landfill to the west of the Site which was previously a sand and gravel mine. The Manthei Hog Farm is located northeast of the Site. To the south of the Site is a wind turbine. There are a few rural residences located in the vicinity of the Site. Some of these residences are located on parcels permitted for sand and gravel mining. Figure 4: Existing Land Use, illustrates these surrounding land uses. ii. Plans. Describe planned land use as identified in comprehensive plan (if available) and any other applicable plan for land use, water, or resources management by a local, regional, state, or federal agency. The Future Land Use Plan within the City of Elk River's Comprehensive Plan' identifies the future land use of the Site as Mining and Development Reserve. The planned land use of the Site is designated as Mining/Development Reserve on the Future Land Use Plan of the Elk River Comprehensive Plan. The Elk River Comprehensive Plan serves as a guide for the City to make decisions regarding the type, location, and density of future development within Elk River. It also serves as the foundation for updating the City's Zoning Ordinance and Zoning Map. The primary objective of these land use categories is to allow mining the land and to subsequently address future land use when development becomes appropriate. Figure 5: Future Land Use illustrates the future land use of the Site and surrounding area as adopted by the Comprehensive Plan. According to the Comprehensive Plan, areas designated Mining are currently being mined or, in the case of the Site, are set aside for future mining. The Elk River Comprehensive Plan indicates that the majority of the mining resources in these areas will be extracted over the next 10 to 40 years. The Project will be active for an estimated 30 years or more based on market demand. Areas designated Development Reserve are outside of the urban service area and will have various development opportunities in the future when mining is complete and services are available. The Project, therefore, is consistent with the goals and guidelines established by the Elk River Comprehensive Plan. 1 WSB Associates, Inc. Elk River Comprehensive Plan, May 2014. Environmental Assessment Worksheet Page 7 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. The Comprehensive plan also addresses Natural Resources. The plan includes a guideline to continue to allow gravel mining in the designated mining areas to make full use of these natural resources. The Natural Resources Plan indicates that the Site is not located in an area with biodiversity significance. The City of Elk River completed a Gravel Mining Area Land Use, Transportation and Utility Plan in 20152 (Gravel Mine Area Study). The Gravel Mine Area includes the Project Area. The purpose of the plan was to develop a vision for future land use, transportation and utility plans for the gravel mining area to be relied upon as mining operations draw to a close and transition into final development. The study is intended to be utilized in conjunction with the City of Elk River's Comprehensive Plan. The Project is compatible with the goals of the Gravel Mine Area Study. This study describes the preferred land use scenario as rural industrial, which includes industrial uses that are not necessarily dependent upon urban services. The study included the timing of availability of urban services and divides the Gravel Mine Area into two Urban Services Areas: 20 Years, and Beyond 20 Years. The Project Area is located in the Beyond 20 Years designation which is consistent with the anticipated 30 year life of the Project. Planned transportation improvements include long term plans of converting US 169 to a freeway system. This includes the construction of interchanges, including one at 221" Street, and a network of frontage and backage roads to connect to freeway access points. The plan includes a new alignment for a frontage/backage road through the Project Area to be constructed beyond 2040. The Reclamation Plan for the Project has been developed to accommodate the future roadway alignment. iii. Zoning, including special districts or overlays such as shoreland, floodplain, wild and scenic rivers, critical area, agricultural preserves, etc. The Site is zoned Commercial Reserve Transitional according to the Elk River Zoning Map. The Project will require a zoning change to include a Mineral Excavation Overlay District over the Site. Mining is a conditional use within the Mineral Excavation Overlay District. The Site is not located in or near a shoreland district, floodplain, wild and scenic river, critical area, or agricultural preserve. b. Discuss the project's compatibility with nearby land uses, zoning, and plans listed in Item 9a above, concentrating on implications for environmental effects. The Project is compatible with current nearby land uses and the Project is consistent with planned future land use but will require a mineral excavation overlay. The Site is surrounded by existing sand and gravel mining operations and the U.S. 169 highway corridor. 2 City of Elk River,April 6,2015. Gravel Mining Area Land Use,Transportation,and Utility Plan retrieved on line at http://elkrivermn.gov/index.aspx?nid=1239. Environmental Assessment Worksheet Page 8 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. The Project will comply with the mineral extraction performance standards established in the Elk River Code of Ordinances which are intended to prevent or minimize environmental and aesthetic impacts on extracted properties, adjacent properties and the community as a whole. The Proposers have developed plans to minimize and mitigate potential impacts including noise, dust, surface water runoff, groundwater contamination, traffic and aesthetics that may result from the extraction activities as required by the Ordinance. The Project includes the development of a comprehensive reclamation plan for the Site. Reclamation grades have been developed to provide continuity to surrounding land. The operators will work with the adjacent mining operators to coordinate reclamation grades with common mining borders as well as the City and MnDOT to facilitate future frontage road alignments as access improvements are developed along U.S. 169. The final landform is expected to be a combination of open water and upland areas which will support future development. c. Identify measures incorporated into the proposed project to mitigate any potential incompatibility as discussed in Item 9b above. Potential impacts of the mining and processing operations on adjacent residential land use include noise and dust, impacts to air quality, traffic impacts and general aesthetics. The Project will incorporate setbacks, buffers and screening to avoid or minimize potential conflicts with surrounding land use. Mining is a conditional use and is subject to specific performance standards established to control potential impacts generated by a mining operation. Proposed setbacks include a 30 foot setback from the all road right-of-ways and parcels not permitted for mining operations. Screening berms may be constructed within setback areas. Berms will be vegetated and provide visual screening. There are limited areas along Baldwin St. NW where the setback area is wooded. The vegetation in these areas will be left in place where practical to provide additional screening. Mining and processing operations will be further screened by the recessed nature of the operations within the mining area. Site operations will be subject to the Minnesota state noise standards. The standards establish allowable noise levels to protect nearby receptors. The noise standards vary according to land use. Residential areas including rural residential and farm houses are considered Noise Area Classification -1 (NAC -1), which is subject to the strictest standards. Noise standards are established for maximum noise levels for daytime and nighttime hours for the L50, the sound level that must not be exceeded for more than 50% of any given hour (30 minutes) and the 1-10, the sound level that must not be exceeded for more than 10% of any given hour (6 minutes). The table below lists the state daytime and nighttime noise standards for Noise Area Classification 1, residential receptors. Environmental Assessment Worksheet Page 9 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. Table 9-1 Minnesota Noise Standards NAC-1 Daytime Nighttime Lso Lio Lso Lio 60 d BA 65 d BA 50 d BA 55 d BA The Site will comply with the state noise standards by maintaining the setback areas and constructing perimeter berms within the setback areas to provide shielding and reduce sound emissions from the Site at nearby receptors. The equipment will be operated at recessed areas on the mine floor. The surrounding excavation slopes provide additional shielding for sound emissions from the equipment. All structures, equipment, and processing plants will be maintained in proper working order, undergo regular maintenance and be kept in a neat condition. Operating equipment will use standard noise control features such as mufflers. On-site equipment will be fitted with broad band back up alarms where practical. Crushing equipment is fitted with spray bars to mitigate the generation of dust during processing. Unpaved internal haul roads will be watered on a regular basis and routine street and entrance sweeping will be conducted to reduce fugitive dust emissions. The processing equipment operates under a MPCA Non-metallic Mining General Air Permit and is subject to certain operating standards which include limits on the amount of emissions, opacity standards, establishes minimum moisture content of feed material, fugitive dust control measures, equipment controls, record keeping and reporting requirements. Processing operations are established at recessed portions of the Site which further reduces fugitive dust emissions associated with the processing equipment. Perimeter berms and vegetated screening help to further reduce any dust traveling offsite. Weeds and other unsightly or noxious vegetation will be controlled as necessary to preserve the appearance of the area.The Site will be operated in a manner to minimize any land use conflicts and to comply with all applicable local, state, and federal permits, standards, and regulations. 10. Geology, soils and topography/land forms: a. Geology - Describe the geology underlying the project area and identify and map any susceptible geologic features such as sinkholes, shallow limestone formations, unconfined/shallow aquifers, or karst conditions. Discuss any limitations of these features for the project and any effects the project could have on these features. Identify any project designs or mitigation measures to address effects to geologic features. The surficial deposits and topography of the Site result from past regional glacial events. Larger landforms are the result of the advance of the St. Croix phase of the Superior Lobe which deposited a red sandy till across the area. A northwest-southeast trending terminal moraine formed at the edge of the Superior Lobe resulting in large geomorphic features in the area. Later, the advance of the Grantsburg Sublobe of the Des Moines Lobe, deposited a calcareous gray till with shale fragments. The Grantsburg till was the last major depositional event in the region. As the Grantsburg Sublobe melted, an esker complex was formed which provides thick sand and gravel deposits characteristic of the area.' 3 City of Elk River, Elk River Gravel Mining District Environmental Impact Statement, 1994. Environmental Assessment Worksheet Page 10 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. The Minnesota Department of Natural Resource's Classification of Aggregate Resources for Sherburne County4 designates the Site as an identified aggregate resource which is an area containing significant aggregate deposits consisting mainly of gravel. It also highlights several gravel pits in the vicinity of the Site. The first bedrock beneath the Site is the Eau Claire Formation based on information from the Sherburne County Geologic Atlas.' The Eau Claire Formation is shaley sandstone that is approximately 70-80' thick. The Eau Claire Formation is underlain by the Mt. Simon Sandstone. The depth to bedrock is approximately 200-350 feet below the surface of the Site.6 The Site is not located in an area where there are susceptible geologic features such as shallow limestone formations, sinkholes, karst features or other significant geologic Site hazards. No impacts to geologic features are expected as a result of the Project. b. Soils and topography - Describe the soils on the site, giving NRCS (SCS) classifications and descriptions, including limitations of soils. Describe topography, any special site conditions relating to erosion potential, soil stability or other soils limitations, such as steep slopes, highly permeable soils. Provide estimated volume and acreage of soil excavation and/or grading. Discuss impacts from project activities (distinguish between construction and operational activities) related to soils and topography. Identify measures during and after project construction to address soil limitations including stabilization, soil corrections or other measures. Erosion/sedimentation control related to stormwater runoff should be addressed in response to Item 11.b.ii. According to the Natural Resources Conservation Service Soil Survey', Site soils consist of the Stonelake-Sandburn soil complex and Sanburn fine sandy loam with slopes ranging from 0 to 40 percent. A complex consists of a combination of two or more soils which are of similar properties and are combined in an intricate way. The complex found at the Site is made up of Stonelake soils, Sandburn soils, and minor components at varying ratios, shown in Table 10-1. Stonelake and Sandburn soils are both formed on glacial outwash. Both soils are in Hydrogeological Soil Group A for each slope category. Group A soils have a high infiltration rate (low runoff potential), consisting mainly of deep, well drained to excessively drained sands or gravely sands. Stonelake and Sandburn soils are not considered Prime Farmland. These soils have no limitations with regard to the proposed mining activity.

The proposed area of soil excavation (mining) is 119 acres, with the remaining area of the Site utilized as setback, buffer and right of way areas. The estimated volume of soil excavation associated is approximately 16 million cubic yards. This includes topsoil and overburden as well as the sand and gravel deposit both above and below the water table. A portion of the deposit may not be suitable for aggregate uses and will remain at the Site and used for reclamation. Additional material may be imported to the Site and used for reclamation. Typically the imported fill will come from a grading project with excess soils. Aggregates will be delivered to the jobsite and the excess soils will be backhauled to the mine site. Material used to backfill created waterbodies will be granular in nature to allow suitable compaction where future development is planned. In the future Baldwin St. NW and 225th Ave. NW may be lowered along common mining borders which would result in additional material to be excavated. NOTE: For silica sand projects, the EAW must include a hydrogeologic investigation assessing the potential groundwater and surface water effects and geologic conditions that could create an increased risk of potentially significant effects on groundwater and surface water. Descriptions of water resources and potential effects from the project in EAW Item 11 must be consistent with the geology, soils and topography/land forms and potential effects described in EAW Item 10. Environmental Assessment Worksheet Page 12 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. 11. Water resources: a. Describe surface water and groundwater features on or near the site in a.i. and a.ii. below. i. Surface water - lakes, streams, wetlands, intermittent channels, and county/judicial ditches. Include any special designations such as public waters, trout stream/lake, wildlife lakes, migratory waterfowl feeding/resting lake, and outstanding resource value water. Include water quality impairments or special designations listed on the current MPCA 303d Impaired Waters List that are within 1 mile of the project. Include DNR Public Waters Inventory number(s), if any. There are no surface waters including lakes, streams, wetlands, intermittent channels, and county/judicial ditches on the Site. The soils found over the Site are well drained with rapid permeability characteristics. There two public waters (15P and 4W) within one mile of the Site. Public Water 15P is a protected basin associated with Tibbets Brook and Rice Lake located west of the Site, U.S. 169 and the Elk River Landfill. Public water 4W is a protected wetland located approximately one mile southeast of the Site. Figure 7: DNR Public Waters, shows the locations of nearby public waters. Although there are no wetlands located on the Site itself, the National Wetland Inventory (NWI) indicates a number of wetlands located in the area surrounding the Site. Figure 8: NWI Wetlands, illustrates the location of wetlands in the surrounding area. Based on information available on the MPCA's Impaired Waters Viewer, there are no MPCA 303d Impaired Waters within one mile of the Site.B ii. Groundwater— aquifers, springs, seeps. Include: 1) depth to groundwater; 2) if project is within a MDH wellhead protection area; 3) identification of any onsite and/or nearby wells, including unique numbers and well logs if available. If there are no wells known on site or nearby, explain the methodology used to determine this. 1) The depth to groundwater at the Site ranges from approximately 13 feet to 92 feet below the ground surface with the variability due to the irregular topography. The groundwater elevation ranges from approximately 956 feet above msl in the southwestern portion of the Site to 960 feet above msl in the northeastern portion of the Site. The direction of groundwater flow is towards the southwest. Groundwater elevation data is from the Elk River Landfill Expansion DEIS.9 2) The Site is not located in a Minnesota Department of Health (MDH) Wellhead Protection Area (WHPA) or a Drinking Water source Management Area (DWSMA).10 3) The Minnesota Well inventory11 was used to identify the wells within a half mile of the Site. Geographic Information System Data was downloaded from the Minnesota Well Index website to obtain coordinates of the wells. The Elk River Landfill is located to the west of the Site, across US 169. The Elk River Landfill has four monitoring wells located $https://www.pca.state.mn.us/water/impaired-waters-viewer-iwav 9 Elk River Landfill Expansion Draft Environmental Impact Statement October 2005 io http://www.heaIth.state.mn.us/divs/eh/water/swp/maps/gis/whpa.pdf "http://www.health.state.mn.us/divs/eh/cwi/ Environmental Assessment Worksheet Page 13 Elk River Sand and Gravel Mines: Tiller Corporation and Max Steininger, Inc. in close proximity to the Site. One well is located north of the Site and is upgradient of both the landfill and the Site. Two wells are located upgradient of the landfill and down gradient of the Site. The fourth well is located up gradient of the landfill and side gradient of the Site. The two wells that are located upgradient of the landfill and downgradient of the Site, 22 OWA and 312 OWA, were included in the 2015 summer quarterly groundwater sampling event 12. Nearby water supply wells and the Elk River Landfill Monitoring Wells are illustrated on Figure 9: Water Wells Within Half Mile of Site. Note that the Elk River Landfill has several more monitoring wells that are part of the landfill's monitoring well network. Figure 9 only indicates those monitoring wells described above, which are located within % mile of the Site. The well logs are included in Attachment 1 and the unique well numbers of the identified wells are: Water Supply Wells within % Mile of Site 417070 437275 500554 578937 650145 421447 456081 545375 609084 Landfill Monitoring Wells within % Mile of Site 498324 683321 420729 646853 b. Describe effects from project activities on water resources and measures to minimize or mitigate the effects in Item U. through Item b.iv. below. i. Wastewater- For each of the following, describe the sources, quantities and composition of all sanitary, municipal/domestic and industrial wastewater produced or treated at the site. 1) If the wastewater discharge is to a publicly owned treatment facility, identify any pretreatment measures and the ability of the facility to handle the added water and waste loadings, including any effects on, or required expansion of, municipal wastewater infrastructure. The mining operations will not discharge wastewater to a publically owned treatment facility. 2) If the wastewater discharge is to a subsurface sewage treatment systems (SSTS), describe the system used, the design flow, and suitability of site conditions for such a system. There is an existing individual sewage treatment system associated with the residence located in the northeastern portion of the Site. The estimated generation rate is 300 gallons per day. Domestic sanitary wastewater produced at the mine sites will not be discharged to a subsurface treatment system. Portable toilets will be used at the mine sites to serve employees. 12 Barr Engineering September 2015, 2015 Summer Quarterly Report, Elk River Landfill, Elk River, Minnesota. Environmental Assessment Worksheet Page 14 Elk River Sand and Gravel Mines: Tiller Corporation and Max Steininger, Inc. Industrial wastewater will be generated seasonally during operation of the washplants. It is anticipated that aggregate washing will be conducted at both mine sites. Each wash plant will discharge up to approximately 1,200-1,500 gpm of process water into on-site sedimentation basins for treatment and reuse back to the washplant. The composition of the industrial wastewater is naturally occurring fine grained sediment that has washed off the larger sand and gravel components of the deposit. 3) If the wastewater discharge is to surface water, identify the wastewater treatment methods and identify discharge points and proposed effluent limitations to mitigate impacts. Discuss any effects to surface or groundwater from wastewater discharges. Wastewater will not be discharged to surface water. Washwater from the wash plant contains suspended solids that are treated in a series of sedimentation ponds and reused. The sedimentation ponds are designed to allow fine particles to settle out of the water. The ponds are built in series so the initial pond removes the majority of the sediment and additional settling occurs throughout the series to the final pond where it is pumped back to the washplant. The sedimentation ponds are cleaned out on a periodic basis to remove the accumulated sediment and maintain treatment efficiency and pond volumes. The sediment, which is composed of naturally occurring silt and clay that has been rinsed off the surface of the aggregates, is allowed to dry. The dried sediment is typically blended with other overburden soils and used in Site reclamation activities. Once sufficient settling has occurred, the water is clean enough to be used in the wash plant again. Washwater is not discharged off-site or to surface water; rather it is recirculated back to the wash plant and recycled. ii. Stormwater- Describe the quantity and quality of stormwater runoff at the site prior to and post construction. Include the routes and receiving water bodies for runoff from the site (major downstream water bodies as well as the immediate receiving waters). Discuss any environmental effects from stormwater discharges. Describe stormwater pollution prevention plans including temporary and permanent runoff controls and potential BMP site locations to manage or treat stormwater runoff. Identify specific erosion control, sedimentation control or stabilization measures to address soil limitations during and after project construction. Prior to construction the majority of stormwater drains internally to low areas, located throughout the Site. The very northern portion of the Site drains off-site. However, due to the rapid permeability of the on-site soils the quantity of runoff is small. During active mining, all stormwater contacting exposed soils within the active mining area will be handled internally and will not be discharged off-site. As mining progresses over the Site, drainage will be directed to low areas within the mine floor where it will temporarily collect, infiltrate through the granular soils or evaporate. Perimeter berms will be constructed within setback areas, shaped, and stabilized with vegetation. Mining activity will create steep slopes on a temporary basis. The active mine face is typically at a slope that ranges from 1:1 to 2:1 (horizontal to vertical). The active face is not vegetated and therefore is subject to erosion. The active face always slopes towards the interior of the mining operation and sedimentation from any erosion of these slopes is Environmental Assessment Worksheet Page 15 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. handled internally through infiltration and evaporation and is and not discharged off- site. Potential impacts to the water quality of stormwater runoff are mitigated through the implementation of a Site specific stormwater pollution prevention plan (SWPPP). The plan provides for stormwater best management practices (BMPs) and phasing of mining operations. Perimeter controls will consist of silt fence, diversion swales and or berms placed around the downslope edge of any area that has the potential to drain off-site during stripping operations. Perimeter controls will remain in place until mining has redirected drainage internally. Infiltration areas and temporary sedimentation basins will be used as needed on the floor of the mine to manage stormwater on the mine floor. The locations of these stormwater management features move as mining progresses through the Site. Establishment of vegetation through seeding and mulching will be conducted as soon as reclaimed areas have been final graded. Erosion control matting, sediment logs and other erosion and sediment control practices will be used as needed throughout the mining operations. Other BMP's for the Site will include good housekeeping, employee training on proper handling of Site materials, on-going maintenance of all Site equipment, containing all stormwater on-site, routine Site inspections, seeding and stabilization of perimeter berms, no discharge of storm water runoff from the Site (all storm water runoff generated within the active mining area will be managed internally), routine street and entrance sweeping to prevent sediment from leaving the Site, rock construction entrances if needed to prevent tracking offsite, and on-going reclamation of the Site once the sand and gravel resource in the perimeter areas has been recovered. Both mining operations will operate under NPDES general permits for non-metallic mineral mining and Site specific stormwater pollution prevention plans (SWPPP) will be prepared for each site. iii. Water appropriation - Describe if the project proposes to appropriate surface or groundwater (including dewatering). Describe the source, quantity, duration, use and purpose of the water use and if a DNR water appropriation permit is required. Describe any well abandonment. If connecting to an existing municipal water supply, identify the wells to be used as a water source and any effects on, or required expansion of, municipal water infrastructure. Discuss environmental effects from water appropriation, including an assessment of the water resources available for appropriation. Identify any measures to avoid, minimize, or mitigate environmental effects from the water appropriation. Sand and gravel washing is proposed at both mining facilities and a DNR water appropriations permit will be required for both Sites. Aggregate washing occurs seasonally during nonfreezing weather conditions (generally April — November). The washplant discharge, which contains a high concentration of suspended solids is treated through a series of sedimentation ponds. Treated water is recycled back through the washplant for reuse. The quantity of washwater depends upon the percentage of fine Environmental Assessment Worksheet Page 16 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. material in the deposit. Flow rates are approximately 1,200-1,500 gallons per minute (gpm) for each plant. The washplants typically use approximately 80% recycled water and 20% make up water. The volume of makeup water will be approximately 250 gpm - 300 gpm for each plant. The plants could run 7 months (mid-April through mid- November), 5 days per week, and 12 hours per day. Under full production, and assuming make-up water requirements of 300 gpm, each plant would use approximately 4,680,000 gallons per month and 32,400,000 gallons per year. It is anticipated that the make-up water will be pumped from a groundwater pond created as part of mining operations or from a production well drilled to support the washplant. iv. Surface Waters a) Wetlands - Describe any anticipated physical effects or alterations to wetland features such as draining, filling, permanent inundation, dredging and vegetative removal. Discuss direct and indirect environmental effects from physical modification of wetlands, including the anticipated effects that any proposed wetland alterations may have to the host watershed. Identify measures to avoid (e.g., available alternatives that were considered), minimize, or mitigate environmental effects to wetlands. Discuss whether any required compensatory wetland mitigation for unavoidable wetland impacts will occur in the same minor or major watershed, and identify those probable locations. There are no wetlands on-site and no anticipated direct or indirect physical effects or alterations to any wetland features. b) Other surface waters- Describe any anticipated physical effects or alterations to surface water features (lakes, streams, ponds, intermittent channels, county/judicial ditches) such as draining, filling, permanent inundation, dredging, diking, stream diversion, impoundment, aquatic plant removal and riparian alteration. Discuss direct and indirect environmental effects from physical modification of water features. Identify measures to avoid, minimize, or mitigate environmental effects to surface water features, including in-water Best Management Practices that are proposed to avoid or minimize turbidity/sedimentation while physically altering the water features. Discuss how the project will change the number or type of watercraft on any water body, including current and projected watercraft usage. There are no surface waters on-site and untreated stormwater contacting exposed soils, stockpiles or mining areas will not be discharged off-site to any adjacent surface waters. The Site's will operate under the General Non-Metallic Mineral Mining National Pollutant Discharge Elimination System (NPDES) stormwater permit and site specific Stormwater Pollution Prevention Plans. In general, active mining areas will drain internally. Perimeter controls, such as silt fence, diversion berms and sediment traps will be utilized where necessary. Direct or indirect physical effects or alterations to surface water features as a result of the Project are not anticipated. Mining will extend in to the water table. Some created water bodies will remain on site as part of final reclamation. Environmental Assessment Worksheet Page 17 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. 12. Contamination/Hazardous Materials/Wastes: a. Pre-project site conditions - Describe existing contamination or potential environmental hazards on or in close proximity to the project site such as soil or ground water contamination, abandoned dumps, closed landfills, existing or abandoned storage tanks, and hazardous liquid or gas pipelines. Discuss any potential environmental effects from pre- project site conditions that would be caused or exacerbated by project construction and operation. Identify measures to avoid, minimize or mitigate adverse effects from existing contamination or potential environmental hazards. Include development of a Contingency Plan or Response Action Plan. Past land use of the Site has been rural residential. There are no known existing soil or groundwater contamination hazards at the Site. The Elk River landfill is located to the west of the Site and is equipped with a liner, a leachate collection system, and a groundwater monitoring system. The Elk River Landfill has taken corrective actions for groundwater contamination associated with the old unlined portion of the landfill to ensure that no groundwater contamination leaves the landfill boundaries.13 The Site is located upgradient of the landfill and the Elk River Landfill EIS concluded that the potential impact to downgradient receptors is low and that it does not appear that there is a potential impact to groundwater or surface water from leachate generated at the landfill. b. Project related generation/storage of solid wastes - Describe solid wastes generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from solid waste handling, storage and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of solid waste including source reduction and recycling. Solid waste generation at the Site is limited to small quantities of solid waste generated from employees. Dumpsters will be used on-site during active operations and a hauling service contracted with to haul the solid waste to a licensed disposal facility. c. Project related use/storage of hazardous materials - Describe chemicals/hazardous materials used/stored during construction and/or operation of the project including method of storage. Indicate the number, location and size of any above or below ground tanks to store petroleum or other materials. Discuss potential environmental effects from accidental spill or release of hazardous materials. Identify measures to avoid, minimize or mitigate adverse effects from the use/storage of chemicals/hazardous materials including source reduction and recycling. Include development of a spill prevention plan. There is no storage of hazardous materials at the Site. Very small quantities of hazardous materials may be brought to the Site when performing routine maintenance of on-site equipment. These materials are considered Materials of Trade and are carried on the service truck that comes to the Site to perform the routine maintenance. The Project will not generate 13 MPCA In the Matter of the Determination of Adequacy of the Environmental Impact Statement for the Elk River Landfill Expansion Project Elk River, Minnesota: Findings of Fact, March 30,2016 Environmental Assessment Worksheet Page 18 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. hazardous waste and therefore is not subject to hazardous waste licensing. The Project will not store hazardous waste and therefore is not subject to Sara Title III Tier II Reporting. Typically a fuel service will be used to fuel on-site equipment. The fuel service truck carries a spill containment kit. If on-site fuel storage is needed, the fuel storage tank will be an above ground double walled tank and meet all MPCA petroleum storage tank requirements. Tanks with capacities over 500 gallons located within 500 feet of a Class 2 surface water or over 1,100 gallon capacity located over 500 feet from a Class 2 surface water require registration with MPCA and must meet other MPCA requirements such as labelling, secondary containment, substance transfer safeguards, routine inspections. If tanks with capacities that require registration are brought to the Site, the operator will register the tanks and comply with the applicable MPCA regulations. d. Project related generation/storage of hazardous wastes - Describe hazardous wastes generated/stored during construction and/or operation of the project. Indicate method of disposal. Discuss potential environmental effects from hazardous waste handling, storage, and disposal. Identify measures to avoid, minimize or mitigate adverse effects from the generation/storage of hazardous waste including source reduction and recycling. Hazardous waste will not be generated at the Site. The service truck performing equipment maintenance will take all used fluids generated from maintenance activities to the operator's main shop where they are properly stored until final disposal. The service truck carries a spill containment kit. 13. Fish, wildlife, plant communities, and sensitive ecological resources(rare features): a. Describe fish and wildlife resources as well as habitats and vegetation on or in near the site. The Site currently provides grassland and wooded habitat for wildlife. The MN DNR Biological Survey (MBS) completed surveys of the natural areas and natural communities that were most likely to support rare plant and animal habitats and rare plant communities. The Site does not include any of these areas or communities. In the land near the Site, there is an Oak Woodland - Brushland to the west, as well as an Oak Forest—Dry Subtype to the southwest.14 b. Describe rare features such as state-listed (endangered, threatened or special concern) species, native plant communities, Minnesota County Biological Survey Sites of Biodiversity Significance, and other sensitive ecological resources on or within close proximity to the site. Provide the license agreement number(LA- ) and/or correspondence number(ERDB# 20160452)from which the data were obtained and attach the Natural Heritage letter from the DNR. Indicate if any additional habitat or species survey work has been conducted within the site and describe the results. 14 Barbara C. Delaney, Natural Communities and Rare Species of Sherburne County, Minnesota. Minnesota County Biological Survey 1993<http://files.dnr.state.mn.us/eco/mcbs/maps/sherburne.pdf> Environmental Assessment Worksheet Page 19 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. The MN DNRs Natural Heritage Information System (NHIS) was queried for the project area and the vicinity within an approximately one mile radius of the Site. The results of the database search are included as Attachment 2, MN DNR Natural Heritage Review, and indicate that there are known occurrences of one state-listed threatened species, Blanding's Turtle, and one state- listed species of special concern, the gopher snake, within one mile of the Site. The query also identified one native plant community, Dry Baron Oak Savanna near the Site. In Minnesota, the statuses of rare species are legally designated in Minnesota Rules Chapter 6134 as endangered, threatened, and special concern species. A species is considered endangered if the species is threatened with extinction throughout all or a significant portion of its range within Minnesota. A species is considered threatened if the species is likely to become endangered within the foreseeable future throughout all or a significant portion of its range within Minnesota. A species is considered a special concern species if it is extremely uncommon in Minnesota, or has unique or highly specific habitat requirements and deserves careful monitoring of its status. Table 13-1 includes a list of one threatened and special concern species that were identified by the query of the NHIS database. None of the animals that were queried for the project area are listed as endangered. No threatened or endangered plants were listed within one mile of the project area. Table 13-1: Minnesota State-Listed Species Near the Project Site Species Type Common Name MN Status A Vertebrate Animal Blanding's Turtle Threatened B Vertebrate Animal Gophersnake Special Concern The following descriptions and pictures of the species listed in the above table are from MN DNR Rare Species Guiders a. Blanding's Turtle (Emydoidea blandingii) The Blanding's turtle was classified as a threatened species in Minnesota in 1984.The range of the Blanding's turtle was formerly more widespread in the eastern and central United States. Its range is now restricted to a small number of states centered on the Great Lakes region, New England and southeastern Canada. Minnesota lies on the northwestern periphery of its range. The Blanding's �� ��` ► turtle has limited population growth due to its relatively low � mobility, high juvenile mortality rate, and low reproductive 15 Minnesota Department of Natural Resources. Rare Species Guide. 2012. Web. June 2012. <http://www.dnr.state.mn.us/rsg/index.html>. Environmental Assessment Worksheet Page 20 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. potential. Loss and degradation of upland and wetland habitats, road kill and nest predation are large factors in mortality rate and threaten the species. Blanding's turtles nest in sparsely vegetated uplands with well-drained, sandy soils. Females may travel up to one mile overland to their nest site, which makes them vulnerable to predators and road kill. Nest predation is very high and the hatchlings are extremely vulnerable to predators and automobiles. b. Gophersnake (Pituophis catenifer) The gophersnake is widely distributed throughout the central and western United States, southwestern Canada, and northern Mexico. Most of the Minnesota records of this species are from counties along the Minnesota, Mississippi, and St. Croix rivers. The bull snake is the subspecies usually found in Minnesota and the Great Plains. ,"� _� The primary threat to this species is habitat loss and degradation ;; : from agricultural activities and urban sprawl and lack of fire. a The gophersnake habitat is primarily areas of well-drained, loose sandy and gravel soils, in prairies, open forests (usually pine and oak), pastures, and brushlands. The gophersnake will hibernate in rodent burrows and fissures in bluffs and rock outcrops. The gophersnake feeds on small animals, including rodents, frogs, and ground nesting birds. The federally-listed threatened and state-listed special concern species, the northern long-eared bat can be found throughout Minnesota. The NHIS database does not contain any occurrences of the northern long-eared bat roosts or hibernaculla within one mile of the Site. The U.S. Fish and Wildlife Service adopted a final 4(d) rule for the northern long-eared bat published on January 14, 2016 and now in effect. Under the final rule, the proposed tree removal activities do not require a permit. c. Discuss how the identified fish,wildlife, plant communities, rare features and ecosystems may be affected by the project. Include a discussion on introduction and spread of invasive species from the project construction and operation.Separately discuss effects to known threatened and endangered species. Although the proposed mining will involve the loss of some wildlife habitat, mining is a temporary activity and it is expected that any species that have the potential to be displaced during mining activities would be expected to return to the area once mining and reclamation activities are complete. Upon reclamation, grassland will be established and waterbodies will be created, providing a variety of wildlife habitat. d. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to fish, wildlife, plant communities, and sensitive ecological resources. The following measures will be incorporated into Site operations in order to minimize the potential for any impact to state listed species on or near the Site. Environmental Assessment Worksheet Page 21 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. 1. Erosion control mesh will be limited to wildlife-friendly materials to avoid entanglement of a variety of reptiles and birds. Wildlife friendly materials include biodegradable rectangular (not square) netting made from flexible natural fibers or biodegradable polyester. Photodegradable products or non-biodegradable plastic erosion control mesh will not be used on site. 2. The MN DNR list of recommendations for areas inhabited by Blanding's Turtles will be followed to the extent practical. These recommendations include such actions as distributing a flyer with an illustration of a Blanding's Turtle to all of the employees that work at the Site. The flyer will also be kept on-site.Turtles that are in imminent danger will be moved out of harm's way by hand.Those that are not in imminent danger will be left undisturbed. If a Blanding's Turtle is observed nesting at the Site, the nest will be marked and left undisturbed. Any silt fencing used as part of stormwater management will be removed as soon as it is no longer needed. Reclamation will include revegetation of the Site with grasses and forbs. 3. Reclamation will be monitored and managed to ensure successful revegetation and wildlife habitat development. 14. Historic properties: Describe any historic structures, archeological sites, and/or traditional cultural properties on or in close proximity to the site. Include: 1) historic designations, 2) known artifact areas, and 3) architectural features. Attach letter received from the State Historic Preservation Office (SHPO). Discuss any anticipated effects to historic properties during project construction and operation. Identify measures that will be taken to avoid, minimize, or mitigate adverse effects to historic properties. A search of the cultural resource database was completed by the Minnesota State Historic Preservation Office (SHPO). No archeological sites were identified in a search of the Minnesota Archaeological Inventory and Historic Structures Inventory for the search area.The letter from SHPO regarding the search results is included as Attachment 3. 15. Visual: Describe any scenic views or vistas on or near the project site. Describe any project related visual effects such as vapor plumes or glare from intense lights. Discuss the potential visual effects from the project. Identify any measures to avoid, minimize, or mitigate visual effects. Visual impacts will be minimized by the construction of perimeter berms and maintenance of wooded setback areas as mining through progresses through the Site. Operating equipment is typically located on the floor of the mine recessed below surrounding grade. Periodically stripping operations will only occur for a limited amount of time at grade. Site operations may be conducted during nighttime hours when lighting on the processing equipment may be needed. This lighting will be downcast and in recessed portions of the Site to minimize any impacts associated with it. Environmental Assessment Worksheet Page 22 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. 16. Air: a. Stationary source emissions - Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants, and any greenhouse gases. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project's effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions. There will be no other stationary source air emissions such as boilers or exhaust stacks. Fugitive dust may be generated from processing equipment, crushing and screening operations. Processing equipment operates under a MPCA Non-metallic Mining General Air Permit and is subject to certain operating standards which include limits on the amount of emissions, opacity standards, establishes minimum moisture content of feed material, fugitive dust control measures, equipment controls, record keeping and reporting requirements. Crushing equipment is fitted with spray bars to mitigate the generation of dust during processing. Processing operations are established at recessed portions of the Site which further reduces fugitive dust emissions associated with the processing equipment. Washplants are not a significant source of fugitive dust emissions. Water used in the washing process saturates the aggregates and eliminates the generation of fugitive dust. Many of the stockpiles will have sufficient moisture content from the washing process to keep fugitive dust levels low during loading operations. The largest source of fugitive dust typically results from haul trucks and other pieces of mining equipment travelling on unpaved haul roads. Fugitive dust from internal haul roads will be controlled by use of dust suppressants such as calcium chloride or by watering. A water truck will be available on-site to water as needed. Fugitive dust from exposed soils and stockpiles will be minimized by and establishing permanent vegetation on perimeter berms and disturbed areas where reclamation grading has been completed and stockpiling materials on the floor of the mine. b. Vehicle emissions - Describe the effect of the project's traffic generation on air emissions. Discuss the project's vehicle-related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle-related emissions. The EIS from the Elk River Gravel Mining District addressed vehicle related air emissions. The EIS concluded that emissions of nitrogen oxides and carbon monoxide can result from truck traffic, but such emissions are limited and not considered a potential problem due to the size and the dispersion potential of the area.16 16 Elk River Mining District Environmental Impact Statement July, 14 1994 Environmental Assessment Worksheet Page 23 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. Vehicle related air emissions include carbon monoxide, hydrocarbons, NOX, particulate matter and sulfur dioxide from employee automobiles, trucks, and excavation equipment such as loaders and back hoes. The Site is not expected to have an adverse impact on air quality. c. Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 16a). Discuss the effect of dust and odors in the vicinity of the project including nearby sensitive receptors and quality of life. Identify measures that will be taken to minimize or mitigate the effects of dust and odors. Fugitive dust is discussed under item 16a. The proposed mining and processing operations will not create odors. 17. Noise Describe sources, characteristics, duration, quantities, and intensity of noise generated during project construction and operation. Discuss the effect of noise in the vicinity of the project including 1) existing noise levels/sources in the area, 2) nearby sensitive receptors, 3) conformance to state noise standards, and 4) quality of life. Identify measures that will be taken to minimize or mitigate the effects of noise. The operation of equipment associated with stripping topsoil and extraction, crushing and transport of aggregate will generate noise. Site operations will be subject to the Minnesota state noise standards. State standards have been established for daytime hours, defined as 7:00 a.m. to 10:00 p.m. and night time hours defined as 10:00 p.m. to 7:00 a.m. Nighttime standards are more restrictive than daytime standards. The project is proposing 24 hour operations and will therefore be subject to both daytime and nighttime standards. Noise standards are applicable at the receptor location and depend upon the type of receptor. Residential receptors are classified as NAC1 which includes farmsteads and rural residential land uses. NAC1 is the most restrictive noise area classification. Very generally, NAC2, NAC3 and NAC 4 are applicable to commercial, industrial and undeveloped land respectively. The rules establish acceptable noise levels for both the L50, the sound level that must not be exceeded for more than 50% of any given hour (30 minutes) and the L10, the sound level that must not be exceeded for more than 10% of any given hour (6 minutes) at the receptor location. Noise levels are expressed in decibels A-weighted (dBA). This is a measure of the relative loudness of sounds in air that are weighted to account for human perception of sound at various frequencies. Table 24-1 presents the applicable state noise standards. Environmental Assessment Worksheet Page 24 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc.

The setback areas and perimeter berms constructed within the setback areas will reduce sound emissions from the site at nearby residents. • Operation of processing equipment on the mine floor utilizing stockpiles and mine faces as a topographic shield to reduce sound levels travelling off-site. • Maintaining operating equipment and use of standard noise control equipment such as mufflers. • Use of broad band back up alarms when possible on equipment operating on-site that frequently backs up. Sound from broad band back up alarms dissipates more quickly due to different frequencies than traditional back up alarms and are approved by the Federal Mine Safety Health Administration (MSHA)for use in at mine sites. • Use of a circular loading pattern for trucks entering the site to reduce back up maneuvers and frequency of back up alarms on haul trucks. 18. Transportation a. Describe traffic-related aspects of project construction and operation. Include: 1) existing and proposed additional parking spaces, 2) estimated total average daily traffic generated, 3) estimated maximum peak hour traffic generated and time of occurrence, 4) indicate source of trip generation rates used in the estimates, and 5) availability of transit and/or other alternative transportation modes. • There will be no designated Site parking spaces. Parking requirements vary throughout the mining season depending upon the nature of the activities that are occurring at any given time. Employee parking will be located across the mine floor and locations may vary depending upon the progression of mining. • The estimated total average daily traffic generated from both site operations combined is estimated to be approximately 120 loads (240 truck trips) per day. • The estimated maximum peak hour traffic generated is 75 loads (150 truck trips) per hour and is expected to occur between 7 am and 9 am. • The source of trip generation rates is based on tons of material imported and exported and average capacity of haul trucks. • Truck hauling is the only transit option available. Environmental Assessment Worksheet Page 25 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. b. Discuss the effect on traffic congestion on affected roads and describe any traffic improvements necessary. The analysis must discuss the project's impact on the regional transportation system. if the peak hour traffic generated exceeds 250 vehicles or the total daily trips exceeds 2,500, a traffic impact study must be prepared as part of the EAW. Use the format and procedures described in the Minnesota Department of Transportation's Access Management Manual, Chapter 5 (available at: http://www.dot.state.mn.us/accessmanagementlresources.html) or a similar local guidance. The two project proposers anticipate sharing a Site access to Baldwin Street as indicated on Sheet C2, Site Plan. The majority of traffic is anticipated to go south on Baldwin to 225th Avenue NW and then both north and south on U.S. 169 which is equipped with turn lanes and acceleration lanes. c. Identify measures that will be taken to minimize or mitigate project related transportation effects. The Project proposers will work with MnDOT and the City of Elk River in developing U.S. 169 corridor improvements including the need for new interchanges and frontage/backage roadways that may be necessary through or near the project area. 19. Cumulative potential effects: (Preparers can leave this item blank if cumulative potential effects are addressed under the applicable EAW Items) a. Describe the geographic scales and timeframes of the project related environmental effects that could combine with other environmental effects resulting in cumulative potential effects. The Site is located in an area characterized by high quality sand and gravel deposits. As a result, sand and gravel mining has been an on-going land use in the area for the past several decades. The operation of several different mine sites spreads this production out among active sites but all within the same geographic area. Collectively these mine sites have been and will continue to produce the volume of material needed to meet local demand. Adding a new source location will have no significant effect on overall cumulative impacts on regional environmental effects. b. Describe any reasonably foreseeable future projects (for which a basis of expectation has been laid) that may interact with environmental effects of the proposed project within the geographic scales and timeframes identified above. No future projects are known at this time although it can be reasonably expected that eventually the majority of land that is currently zoned mineral excavation district overlay or guided mining will be mined in the future. c. Discuss the nature of the cumulative potential effects and summarize any other available information relevant to determining whether there is potential for significant environmental effects due to these cumulative effects. Environmental Assessment Worksheet Page 26 Elk River Sand and Gravel Mines:Tiller Corporation and Max Steininger, Inc. The Environmental Impact Statement (EIS) for the Elk River Mining District, which encompassed 2,865 acres immediately adjacent to the Project, included an analysis of cumulative impacts related to noise, air quality, traffic, dust and surface and groundwater quality. The City of Elk River was the Responsible Government Unit conducting the environmental review. The Elk River Mining District EIS concluded that any negative cumulative effects could be regulated within the framework of the CUPS issued for each individual mining operation. It is anticipated that, as is the case with the other existing mining operations, the CUP will contain conditions which will address and satisfactorily regulate potential environmental impacts associated with noise, fugitive dust, surface and groundwater protection, and Site reclamation. 20. Other potential environmental effects: If the project may cause any additional environmental effects not addressed by items 1 to 19, describe the effects here, discuss the how the environment will be affected, and identify measures that will be taken to minimize and mitigate these effects. There are no other known potential environmental impacts resulting from this project that are not addressed in items 1-19. RGU CERTIFICATION.

Based on this query, rare features have been documented within the search area (for details, please visit the Rare Species Guide at http://www.dnr.state.mn.us/rse/index.html for more information on the biology, habitat use, and conservation measures of these rare species). Please note that the following rare features may be adversely affected by the proposed project: State-listed Species • Blanding's turtles (Emydoidea blandingii), a state-listed threatened species, have been reported in the vicinity of the proposed project. Although we have no records from directly within the project site, turtles may use the site if it contains suitable habitat. Blanding's turtles use upland areas up to and over a mile distant from wetlands, as well as wetlands. Uplands are used for nesting, basking, periods of dormancy, and traveling between wetlands. Because of the tendency to travel long distances over land, Blanding's turtles regularly travel across roads and are therefore susceptible to collisions with vehicles. Any added mortality can be detrimental to populations of Blanding's turtles, as these turtles have a low reproduction rate that depends upon a high survival rate to maintain population levels. Other factors believed to contribute to the decline of this species include wetland drainage and degradation, and the development of upland habitat. For your information, I have attached a Blanding's turtle fact sheet that describes the habitat use and life history of this species. The fact sheet also provides two lists of recommendations for avoiding and minimizing impacts to this rare turtle. Please refer to the first list of recommendations for your project. In addition, if erosion control mesh will be used, the DNR recommends that the mesh be limited to wildlife-friendly materials (see enclosed fact sheet). If greater protection for turtles is desired, the second list of additional recommendations can also be implemented. www.mndnr.gov AN EQUAL OPPORTUNITY EMPLOYER The attached flyer should be given to all contractors working in the area. If Blanding's turtles are encountered on site, please remember that state law and rules prohibit the destruction of threatened or endangered species, except under certain prescribed conditions. If turtles are in imminent danger they should be moved by hand out of harm's way, otherwise they should be left undisturbed. • The gopher snake (Pituophis catenifer), a state-listed species of special concern, has been documented in the vicinity of the proposed project and may be encountered on site. For more information on the biology, habitat use, and conservation measures of this rare snake please visit http://dnr.state.mn.us/reptiles amphibians/index.html. Given the presence of these rare snakes, the DNR recommends that the use of erosion control mesh, if any, be limited to wildlife-friendly materials (see enclosed fact sheet). Federally Protected Species • The northern long-eared bat (Myotis septentrionalis), federally listed as threatened and state-listed as special concern, can be found throughout Minnesota. During the winter this species hibernates in caves and mines, and during the active season (approximately April- October) it roosts underneath bark, in cavities, or in crevices of both live and dead trees. Pup rearing is during June and July. Activities that may impact this species include, but are not limited to, wind farm operation, any disturbance to hibernacula, and destruction/degradation of habitat (including tree removal). The U.S. Fish and Wildlife Service (USFWS) has published a final 4(d) rule that identifies prohibited take. To determine whether you need to contact the USFWS, please refer to the USFWS Key to the Northern Long-Eared Bat 4(d) Rule (see links below). Please note that the NHIS does not contain any known occurrences of northern long-eared bat roosts or hibernacula within an approximate one-mile radius of the proposed project. Environmental Review and Permitting • The Environmental Assessment Worksheet should address whether the proposed project has the potential to adversely affect the above rare features and, if so, it should identify specific measures that will be taken to avoid or minimize disturbance. Sufficient information should be provided so the DNR can determine whether a takings permit will be needed for any of the above protected species. • Please include a copy of this letter in any state or local license or permit application. Please note that measures to avoid or minimize disturbance to the above rare features may be included as restrictions or conditions in any required permits or licenses. The Natural Heritage Information System (NHIS), a collection of databases that contains information about Minnesota's rare natural features, is maintained by the Division of Ecological and Water Resources, Department of Natural Resources. The NHIS is continually updated as new information becomes available, and is the most complete source of data on Minnesota's rare or otherwise significant species, native plant communities, and other natural features. However, the NHIS is not an exhaustive inventory and thus does not represent all of the occurrences of rare features within the state. Therefore, ecologically significant features for which we have no records may exist within the Page 2 of 3 project area. If additional information becomes available regarding rare features in the vicinity of the project,further review may be necessary. The enclosed results include an Index Report of records in the Rare Features Database, the main database of the NHIS. To control the release of specific location data, the report is copyrighted and only provides rare features locations to the nearest section. The Index Report may be reprinted, unaltered, in any environmental review document (e.g., EAW or EIS), municipal natural resource plan, or report compiled by your company for the project listed above. If you wish to reproduce the Index Report for any other purpose, please contact me to request written permission. For environmental review purposes, the results of this Natural Heritage Review are valid for one year; the results are only valid for the project location (noted above) and the project description provided on the NHIS Data Request Form. Please contact me if project details change or for an updated review if construction has not occurred within one year. The Natural Heritage Review does not constitute review or approval by the Department of Natural Resources as a whole. Instead, it identifies issues regarding known occurrences of rare features and potential effects to these rare features. To determine whether there are other natural resource concerns associated with the proposed project, please contact your DNR Regional Environmental Assessment Ecologist (contact information available at http://www.dnr.state.mn.us/eco/ereview/erp regioncontacts.html). Please be aware that additional site assessments or review may be required. Thank you for consulting us on this matter, and for your interest in preserving Minnesota's rare natural resources. An invoice will be mailed to you under separate cover. Sincerely, so_lz� Samantha Bump Natural Heritage Review Specialist enc.

The types of wetlands used include ponds, marshes, shrub swamps, bogs, and ditches and streams with slow-moving water. In Minnesota, Blanding's turtles are primarily marsh and pond inhabitants. Calm,shallow water bodies(Type 1-3 wetlands)with mud bottoms and abundant aquatic vegetation (e.g., cattails, water lilies) are preferred, and extensive marshes bordering rivers provide excellent habitat. Small temporary wetlands(those that dry up in the late summer or fall) are frequently used in spring and summer--these fishless pools are amphibian and invertebrate breeding habitat, which provides an important food source for Blanding's turtles. Also,the warmer water of these shallower areas probably aids in the development of eggs within the female turtle. Nesting occurs in open(grassy or brushy)sandy uplands, often some distance from water bodies. Frequently, nesting occurs in traditional nesting grounds on undeveloped land. Blanding's turtles have also been known to nest successfully on residential property(especially in low density housing situations),and to utilize disturbed areas such as farm fields,gardens,under power lines,and road shoulders (especially of dirt roads). Although Blanding's turtles may travel through woodlots during their seasonal movements,shady areas(including forests and lawns with shade trees)are not used for nesting. Wetlands with deeper water are needed in times of drought,and during the winter. Blanding's turtles overwinter in the muddy bottoms of deeper marshes and ponds,or other water bodies where they are protected from freezing. LIFE HISTORY Individuals emerge from overwintering and begin basking in late March or early April on warm,sunny days. The increase in body temperature which occurs during basking is necessary for egg development within the female turtle. Nesting in Minnesota typically occurs during June, and females are most active in late afternoon and at dusk. Nesting can occur as much as a mile from wetlands. The nest is dug by the female in an open sandy area and 6-15 eggs are laid. The female turtle returns to the marsh within 24 hours of laying eggs. After a development period of approximately two months,hatchlings leave the nest from mid-August through early-October. Nesting females and hatchlings are often at risk of being killed while crossing roads between wetlands and nesting areas. In addition to movements associated with nesting,all ages and both sexes move between wetlands from April through November. These movements peak in June and July and again in September and October as turtles move to and from overwintering sites. In late autumn(typically November),Blanding's turtles bury themselves in the substrate(the mud at the bottom)of deeper wetlands to overwinter. IMPACTS/THREATS/ CAUSES OF DECLINE • loss of wetland habitat through drainage or flooding(converting wetlands into ponds or lakes) • loss of upland habitat through development or conversion to agriculture • human disturbance,including collection for the pet trade* and road kills during seasonal movements • increase in predator populations(skunks,raccoons,etc.)which prey on nests and young *It is illegal to possess this threatened species.

List 1 describes minimum measures which we recommend to prevent harm to Blanding's turtles during construction or other work within Blanding's turtle habitat. List 2 contains recommendations which offer even greater protection for Blanding's turtles populations;this list should be used in addition to the first list in areas which are known to be of state-wide importance to Blanding's turtles(contact the DNR's Natural Heritage and Nongame Research Program if you wish to determine if your project or home is in one of these areas),or in any other area where greater protection for Blanding's turtles is desired.

Contact your DNR Regional Nongame Specialist for further information on wildlife tunnels. Roads should be ditched,not curbed or below grade. If Roads should be ditched,not curbed or below grade. curbs must be used,4 inch hi h curbs at a 3:1 slope are preferred(Blanding's turtles have great difficulty climbing traditional curbs;curbs and below grade roads trap turtles on the road and can cause road kills).

UTILITIES Utility access and maintenance roads should be kept to a minimum(this reduces road-kill potential). Because trenches can trap turtles,trenches should be checked for turtles prior to being backfilled and the sites should be returned to original grade. LANDSCAPING AND VEGETATION MANAGEMENT Terrain should be left with as much natural contour as As much natural landscape as possible should be preserved possible. (installation of sod or wood chips,paving,and planting of trees within nesting habitat can make that habitat unusable to nesting Blanding's turtles). Graded areas should be revegetated with native grasses Open space should include some areas at higher elevations and forbs(some non-natives form dense patches through for nesting. These areas should be retained in native which it is difficult for turtles to travel). vegetation,and should be connected to wetlands by a wide corridor of native vegetation. Vegetation management in infrequently mowed areas-- Ditches and utility access roads should not be mowed or such as in ditches,along utility access roads,and under managed through use of chemicals. If vegetation power lines-- should be done mechanically(chemicals management is required,it should be done mechanically, should not be used). Work should occur fall through as infrequently as possible,and fall through spring spring(after October 1St and before June 1St). (mowing can kill turtles present during mowing,and makes it easier for predators to locate turtles crossing roads). Protecting Blanding's Turtle Nests: Most predation on turtle nests occurs within 48 hours after the eggs are laid. After this time,the scent is gone from the nest and it is more difficult for predators to locate the nest. Nests more than a week old probably do not need additional protection,unless they are in a particularly vulnerable spot,such as a yard where pets may disturb the nest. Turtle nests can be protected from predators and other disturbance by covering them with a piece of wire fencing(such as chicken wire),secured to the ground with stakes or rocks. The piece of fencing should measure at least 2 ft.x 2 ft.,and should be of medium sized mesh(openings should be about 2 in.x 2 in.). It is very important that the fencing be removed before August 18 so the young turtles can escape from the nest when they hatch! REFERENCES 'Association for Biodiversity Information.

Blanding's turtles are state-listed as Threatened and are protected under Minnesota Statute 84.095, Protection of Threatened and Endangered Species. Please be careful of turtles on roads and in construction sites. For additional information on turtles, or to report a Blanding's turtle sighting, contact the DNR Nongame Specialist nearest you: Bemidji (218-308-2641); Grand Rapids (218-327-4518); New Ulm (507-359-6033); Rochester (507-206-2820); or St. Paul (651-259-5772). DESCRIPTION: The Blanding's turtle is a medium to large turtle (5 to 10 inches) with a black or dark blue, dome-shaped shell with muted yellow spots and bars. The bottom of the shell is hinged across the front third, enabling the turtle to pull the front edge of the lower shell firmly against the top shell to provide additional protection when threatened. The head, legs, and tail are dark brown or blue-gray with small dots of light brown or yellow. A distinctive field mark is the bright yellow chin and neck. BLANDING'S TURTLES DO NOT MAKE GOOD PETS IT IS ILLEGAL TO KEEP THIS THREATENED SPECIES IN CAPTIVITY SUMMARY OF RECOMMENDATIONS FOR AVOIDING AND MINIMIZING IMPACTS TO BLANDING'S TURTLE POPULATIONS (see Blanding's Turtle Fact Sheet for full recommendations) • This flyer should be given to all contractors working in the area. Homeowners should also be informed of the presence of Blanding's turtles in the area. • Turtles that are in imminent danger should be moved, by hand, out of harm's way. Turtles that are not in imminent danger should be left undisturbed to continue their travel among wetlands and/or nest sites. • If a Blanding's turtle nests in your yard, do not disturb the nest and do not allow pets near the nest. • Silt fencing should be set up to keep turtles out of construction areas. It is critical that silt fencing be removed after the area has been revegetated. • Small, vegetated temporary wetlands should not be dredged, deepened, or filled. • All wetlands should be protected from pollution; use of fertilizers and pesticides should be avoided, and run-off from lawns and streets should be controlled. Erosion should be prevented to keep sediment from reaching wetlands and lakes. • Roads should be kept to minimum standards on widths and lanes. • Roads should be ditched, not curbed or below grade. If curbs must be used, 4" high curbs at a 3:1 slope are preferred. • Culverts under roads crossing wetland areas, between wetland areas, or between wetland and nesting areas should be at least 36 in. diameter and flat-bottomed or elliptical. • Culverts under roads crossing streams should be oversized (at least twice as wide as the normal width of open water) and flat-bottomed or elliptical. • Utility access and maintenance roads should be kept to a minimum. • Because trenches can trap turtles, trenches should be checked for turtles prior to being backfilled and the sites should be returned to original grade. • Terrain should be left with as much natural contour as possible. • Graded areas should be revegetated with native grasses and forbs. • Vegetation management in infrequently mowed areas -- such as in ditches, along utility access roads, and under power lines -- should be done mechanically (chemicals should not be used).

Yet the use of these materials continues in many cases,without consideration for wildlife impacts. Plastic netting is frequently used for erosion control during construction and landscape projects and can negatively impact terrestrial and aquatic wildlife populations as well as snag in maintenance machinery resulting in costly repairs and delays. However, wildlife friendly erosion control materials do exist, and are sold by several large erosion control material companies. Below are a few key considerations before starting a project. Know Your Options • Remember to consult with local natural resource authorities(DNR,USFWS,etc.)before starting a project. They can help you identify sensitive areas and rare species. • When erosion control is necessary, select products with biodegradable netting(natural fiber, biodegradable polyesters,etc.). • DO NOT use products that require UV-light to biodegrade (also called, "photodegradable").
