Small Scale Mineral Extraction Permit for 2023 AGENDA SECTION: Public Hearing PREPARED BY: Julia Hogan, Planner AGENDA NO. 6.e. ATTACHMENTS: Site Location; 2023 Mining Permit; Project Narrative; Location Map; Haul Route; Current Conditions; Mine Plan; Reclamation Plan; Site and Aerial Photographs APPROVED BY: AK RECOMMENDED ACTION: Motion to recommend renewal of the Max Steininger, Inc. Small Scale Mineral Extraction Permit for 2023, subject to the terms and conditions in the attached Draft 2023 Conditions for Mineral Extraction. SUMMARY Applicant and property owner: Max Steininger, Inc., 3080 Lexington Avenue South, Eagan, MN Location: Approximately one mile east of US Highway 52 along CSAH 42; adjacent to 4322 145th Street East Area in acres: 78.91 acres (overall site); 37 acres (mining area); 5 acres (active mining) Mining Area: 3.5 acres of current active mine plus 1-1.5 acres of additional area Comp. Guide Plan Designation: LDR– Low Density Residential, MDR – Medium Density Residential and HDR – High Density Residential Current Zoning: AG – Agriculture The Planning Commission is being asked to consider a request from Max Steininger, Inc. to renew the existing Small-Scale Mineral Extraction Permit for its operation located along County Highway 42 and east of State Highway 52 in the southeastern portion of Rosemount. Small Scale Mineral Extraction is permitted in the City as an Interim Use Permit (IUP) within specified areas, and the permit for such uses expires after one year. The applicant applied for the initial mining permit IUP in the summer of 2018 and was granted a renewal of the permit that extended it through 2022. The current request would extend the mining permit for one additional year through the end of 2023. BACKGROUND The applicant, Max Steininger, Inc. (affiliated with the property owner County Road 42 Properties), owns a construction and excavation business in Eagan and received approval from the City in 2018 to start a new mining operation next to the Danner Inc. mine along Highway 42. Over the last four and a half years, the applicant has commenced mining activities in the northern-most portions of their Phase 1 mining area, constructed an access road for the mine, and installed a berm along the access road using topsoil from the active mining area. Because the mineral extraction use is closely tied to the applicant’s primary business, there will be limited sales of materials to outside projects from the mine. The applicant has provided a detailed application packet for the mining renewal and has hired Sunde Engineering to help prepare plans 2 for the site and to provide information as required under the City’s mineral extraction ordinance. Since starting mining operations on the property in the summer of 2018, the applicant has indicated that approximately 134,800 tons of material have been removed from the site, all of which were mined from the extreme northern portion of the Phase 1 mining area. Roughly 5 acres of the 15 acres in Phase 1 have been stripped and mining has progressed across 3.5 acres of that stripped area, and approximately 26,800 tons of material were removed in 2022. The updated topographic survey for the operation shows that current elevation of the mining floor is at 840 feet, which is the maximum depth allowed under the mining permit. In addition to the mining, the applicant finished construction of the berm planned along the entrance road in early 2020. The berm was moved further to the east along the access road to provide a more direct and effective screen between the mining road and nearby residential structures. It was also completed to its planned height of 15 feet with an appropriate cover material to prevent erosion, dust and soil loss. For 2023, the applicant intends to extract 30,000 tons of material from 3.5 acres of current active mining area plus 1-1.5 acres of additional mining area. As noted by the applicant, material is excavated and processed on site. Processing consists of crushing and screening with portable processing equipment set up upon the floor of the mine recessed from the surrounding grade to reduce noise and dust emissions. Material is stockpiled on the floor of the mine. The applicant also intends to perform recycling of concrete and asphalt material on the property, which will be crushed and blended with on-site materials to produce recycled aggregate blends. The recycling operations will likely not occur in 2023 and will commence once there is a sufficiently large enough mine floor area in which to work. The applicant will need to obtain approval by the Dakota County Environmental Management Department prior to the recycling operations. No haul back material was brought to the site in 2022, and no topsoil has been removed from the property (most of the stripped soil has been used to construct the berm). ISSUE ANALYSIS Aggregate mining is reviewed through an interim use permit which is a Quasi-Judicial action. As such, the City has a set of standards and requirements for review. Generally, if the applications meet the ordinance requirements they must be approved. The standards and requirements for this mineral extraction are detailed in Section 11-10-4 of the Zoning Ordinance and the attached Mineral Extraction permit. The subject property is zoned AG – Agriculture and meets or exceeds the applicable performance standards for small scale mineral extraction. Small scale mineral extraction is listed as an interim use within the Agriculture district. The table below details the current land use, zoning, and future land use information for the surrounding properties. These properties are all currently zoned Agricultural and are located within the 2030 Metropolitan Urban Service Area (MUSA). The 2040 Future Land Use Map anticipates a mixture of low, medium, and high density residential on the applicant’s parcel. Future reclamation of the site will need to be performed before an impacted area may be developed for housing in accordance with the City’s future land use plan. Surrounding Land Use and Zoning Information Direction Current Land Use Zoning Guided Land Use North Agriculture Agricultural BP – Business Park South Agriculture Agricultural LDR – Low Density Residential East Agriculture/Mining Agricultural LDR, MDR, and HDR – Low, Medium, and High Density Residential West Agriculture Agricultural CC- Community Commercial LDR, MDR and HDR – Low, Medium, and High Density Residential 3 Access to the Steiniger mine comes from County Road 42 via a gravel road along the eastern edge of the property. The applicant has secured the necessary access permits from Dakota County for the access road, and will need to continue to abide by the terms and conditions of this permit throughout the life of the mine. The permit application notes that haul routes within the City will continue to be County Road 42 to State Highway 52. As a part of the annual review of all mineral extraction permits, staff performs an inspection of the site and consults with the Rosemount Police Department regarding any police activity. No ordinance or permit condition violations were apparent during the inspection, and ground cover has been established on all restored areas. Police records found no incidents at the subject property during 2022. RECOMMENDATION Staff recommends renewal of the Small Scale Mineral Extraction Permit for Max Steininger, Inc. for 2023 based upon a review of the information submitted by the applicant, the mineral extraction standards in Section 11-10-4 of the City Code, City Police records and the attached draft permit. 1 Mineral Extraction Permit 20232 Conditions for Small Scale Mineral Extraction Permit MAX STEININGER, INC.

Application for 2023 ANNUAL PERMIT REISSUANCE SMALL SCALE MINERAL EXTRACTION City of Rosemount, Minnesota Sunde Engineering, PLLC 10830 Nesbitt Avenue South Bloomington, MN 55437 952 881-3344 MAX STEININGER, INC. APPLICATION FOR 2023 ANNUAL PERMIT REISSUANCE SMALL SCALE MINERAL EXTRACTION ROSEMOUNT, MINNESOTA 1.0 INTRODUCTION Max Steininger, Inc. (Steininger) operates a Small Scale Mineral Extraction operation on a parcel of property located in the City of Rosemount (Site). The Site was originally permitted in 2018 and requires annual renewals. This annual renewal application is for 2023 operations. The Site encompasses 79 acres, of which 38 acres will be mined. The property is located just south of CSAH 42 and approximately three-quarters of a mile East of US Highway 52. The Site is zoned Agricultural (AG) and is located within the Small Scale Mineral Extraction Overlay District. Figure 1: USGS Quad Map Excerpt Shows the location of the Site with respect to the surrounding area. Surrounding land use includes mining operations to the west, agricultural uses to the north south and east, and a golf course to the northwest. 2.0 ANNUAL REPORT As required the applicant shall annually submit to the council written estimates of: 2.1 The total area of the mineral extraction operation (expressed in acres) to be actively mined during the forthcoming year; The active mine area in 2023 will be approximately 5 acres and will include approximately 3.5 acres of current active mine area plus 1 to 1.5 acres of additional area to be mined in 2023. 2.2 The area under the permit (expressed in acres) which will not be actively mined during the forthcoming year. The remaining area within Phase 1 which will not be mined in 2023 is approximately 10 acres. 2.3 Security Bond: Steininger will post a reclamation bond equal to $7,500 /acre of open mine area in a form acceptable to the City, (cash escrow or letter of credit) in an amount determined by the council. The reclamation bond may be adjusted on an annual basis to reflect the amount of active mine area open and unreclaimed and the amount of mine area reclaimed. The total anticipated open area at the end of 2023 is five acres. The security shall remain in full force and effect for a minimum period of one year after expiration of the extraction permit to guarantee the required reclamation as well as the other requirements herein provided. 3.0 2022 MINE PLAN NARRATIVE Five acres have been stripped and mining has progressed across approximately 3.5 of the stripped area within the northern portion of Phase 1. Approximately 26,800 tons of material were removed in 2022. Material from the stripping operation was used to complete the berm along the access road which was seeded and mulched to establish vegetation upon completion. Instead of the berm extending along CSAH 42, the topsoil stockpile located adjacent to the active mining operation was reshaped to provide screening of the operation from CSAH 42. Mining is setback from the county road by over 700 feet. The remainder of the Site is farmed with no buildings or structures located on Site. During the 2023 mining season, it is anticipated that approximately 30,000 tons of material will be mined within Phase 1, in an area that was previously stripped. No further stripping in 2023 is anticipated. The County is monitoring access on County Road 42 and has reserved the right to require a turn lane should the need arise. In accordance with the permit, the operator has not removed any topsoil from the site. Topsoil is stockpiled on site and will be used to perform site reclamation. The operation is still in the process of mining out a large enough area to conduct processing and stockpiling operations on, and no clean haul back reclamation fill material has been brought to the site to date. Clean material from various job sites is expected to be hauled back to the site in the future and used in reclamation backfilling and sloping. 4.0 APPLICATION FORM 4.1 Legal description: See Attachment 1 4.2 Name, address, phone number of the applicant, landowner, and person in charge of the mining operation: Greg Steininger Max Steininger, Inc. 3080 Lexington Avenue South Eagan, MN 55121 651 454-6620 4.3 Names and addresses of adjacent landowners within one quarter mile of the Site: There are nine property owners located within one-quarter mile of the Site. A list of their names and addresses obtained from Dakota County GIS tax records is provided in Attachment 2. 4.4 The purpose of the proposed excavation: The mining operation supplies material predominantly for use in the operator’s own construction projects with limited sales to outside parties. 4.5 The estimated time required to complete the proposed excavation and rehabilitation: The estimated life of the excavation and reclamation operation is twenty years. The life of the Site will depend upon the market demand and general development and construction activity in the area. 2019 was the first full year of operation. To date approximately 134,800 tons of material have been removed from the Site. 4.6 The names of the highways, streets, or other public roadways within the city upon which the material shall be transported: Material is hauled from the Site accessing CSAH 42 and then west to US 52 as illustrated on Figure 2, Haul Routes. Some local jobs may result in variations to this general haul route. 5.0 SITE ANALYSIS Mine operations began with the construction of the Site access road. Five acres have been stripped, construction of the screening berm along the access road has been completed and the berm has been seeded. Instead of a berm along CSAH 42, the berm wraps along the base of Phase 1 to screen operations from the highway. (There is over 700 feet of setback between highway and mining limits). The berm has been seeded and mulched. Mining has progressed across approximately 3.5 acres of the northern portion of Phase 1. Approximately 134,8000 tons of material have been removed from the site to date. During the 2023 mining season, it is anticipated that an additional 1 to 1.5 acres will be mined. This area has already been stripped in preparation of mining. An estimated 30,000 tons of material will be removed from the Site in 2023. The remainder of the Site is farmed with no buildings or structures located on Site. Surrounding land uses are predominantly agricultural and rural residential land uses, a golf course to the northwest, and active mining operations to the east. Figure 1, USGS Quad Map Excerpt, illustrates features of the Site and surrounding land. Sheet C1, Existing Conditions, illustrates site features in more detail. The Site is not located within a floodplain.1 There are no watercourses or wetlands located on the Site according to the National Wetland Inventory. The northern portion of the Site borders CSAH 42. The topography of the Site slopes to the South and ranges in elevation from 852 feet above mean sea level (msl) near CSAH 42 to 914 feet above msl at the southern property line. Slopes vary from 1% to 25%. There is a 25 foot rise in elevation that runs northwest to southeast through the northern portion of 1 Federal Emergency Management’s Flood Insurance Rate Map for Dakota County, MN 270 37C 0235E retrieved online at https://msc.fema.gov/portal/search?AddressQuery=Rosemount%20MN#searchresultsanchor the property. The slope is vegetated with brush and grass. The mining activity will occur into the upper terrace progressing into the central and southern portion of the Site. There are two residential properties located to the northwest of the proposed mine limits. Mining areas have been planned to have the least impact on the nearest residential land uses. The aerial photograph inset below illustrates a view of the Site. Aerial photograph is from Minnesota Geospatial Commons dated 9-10-2021. Inset 1: Minnesota Geospatial Commons Aerial Photograph The elevation of the water table beneath the Site is illustrated on Sheet C1, Existing Conditions. The water table varies from 795 feet above msl in the northeast corner of the Site to just over 810 feet above msl in the southwest corner of the Site. The direction of groundwater flow is to the northeast. Water table elevation information is from area well records and information contained in the Dakota County Geologic Atlas. All mining activity will occur above the water table. 6.0 Mine Operations Plan: 6.1 Site Preparation: An access road into the Site has been constructed. A screening berm is complete and has been seeded to establish vegetation. 6.2 Phasing: The Site is mined in phases. Each phase is 15 acres or less. In accordance with the City of Rosemount Small Scale Mineral Extraction Code, the 2023 Mineral Extraction Permit will be valid for Phase 1 only. An extraction permit for Phase 2 will not be issued until at least 70% of the Phase 1 has been reclaimed in accordance with an approved reclamation plan. Mining will proceed in a north to south direction through Phase 1. 6.3 Mining and Processing: Material is excavated and processed on site. Processing consists of crushing and screening with portable processing equipment set up upon the floor of the mine recessed from the surrounding grade to reduce noise and dust emissions. Material is stockpiled on the floor of the mine. Recycling of concrete and asphalt will also take place on site. These materials will be crushed and blended with on-site materials to produce recycled aggregate blends. Clean soil fill may be backhauled to the site from the operator’s construction jobs and used in site reclamation. 6.4 Setbacks: A minimum 30-foot setback is maintained between the mining excavation and all property lines, except the eastern property line where there is a common mining border. The setback from CSAH 42 will be over 700 feet. Processing equipment will be setback over a minimum of 1,000 feet from any residential structure. 6.5 Fencing: The operator has installed safety fencing along the southerly top of the excavation. No other fencing is proposed. The Site entrance is secured with a locking gate. 6.6 Appearance and Screening: All machinery will be kept operational. Abandoned machinery and any rubbish will be promptly removed from the mining area. Reclamation will be completed within three months of termination of mining activity. This includes the dismantling of all buildings and structures incidental to the mining operations. 7.0 OPERATING STANDARDS 7.1 Noise The mine operates in compliance with all State noise standards. State standards have been established for daytime hours and nighttime hours. The Site will operate entirely within the daytime hours. Table 1.1 Minnesota Noise Standards for Residential Land Uses Daytime Nighttime L50 L10 L50 L10 60 dBA 65 dBA 50 dBA 55 dBA Measures will be taken at the Site to minimize noise emissions from the Site. These measures include screening berms, recessing mining and processing activities below the surrounding grade so the topography shields and absorbs sound energy reducing sound emissions. Maintenance of operating equipment and use of standard noise control equipment such as mufflers will also reduce sound levels at the Site. 7.2 Hours: All excavation operations shall be conducted between 7:00 A.M. and 7:00 P.M., Monday through Saturday only. 7.3 Explosives: No explosives will be used at the Site. 7.4 Fugitive Dust: All practical means to reduce the amount of dust generated by excavation operations will be utilized. Fugitive dust will be minimized by recessed operations, spray bars on processing equipment, dust suppressants on internal haul roads, and the establishment of permanent vegetation on perimeter berms and reclaimed areas. Fugitive dust will not exceed air pollution standards established by the Minnesota Pollution Control Agency (MPCA). Processing equipment is subject to a MPCA air emissions general permit for non-metallic mineral mining which includes standards for fugitive dust emissions. 7.5 Water Pollution: The Site operates under an MPCA General Stormwater Permit for Nonmetallic Mineral Mining. (General NPDES Permit) Under the terms of the General NPDES permit, the mining is conducted under a site specific stormwater pollution prevention plan (SWPPP). This plan includes industry best management practices for managing stormwater and preventing contamination of surface and groundwater. The majority of stormwater will be managed internally through infiltration. Fuel storage will be in accordance with MPCA regulations. The SWPPP also contain spill prevention, response and reporting measures. No waste products or processed residue, including untreated wash water shall be deposited in any public waters of the State of Minnesota. 7.6 Topsoil Preservation: All topsoil shall be retained at the Site until the completion of mining and used for reclamation. 7.7 Excavation Slopes: All excavation slopes other than the working face shall not exceed 1:1 (horizontal to vertical) unless a steeper slope is approved by the City. No excavation shall take place adjacent to a public roadway or waterway. 7.8 Equipment: All equipment and machinery will be located within the mine and operated in a manner that minimizes dust, noise, and vibration. Power drives or power producing machines will be setback a minimum of one thousand feet from a residential structure. Fugitive dust will be controlled from internal haul roads and the access road using water or calcium chloride. 7.9 Processing: Portable crushing and screening equipment will be brought to the site on a periodic basis to process material. A portable washplant may also be periodically operated at the site. A MDNR Water Appropriation permit is required prior to conducting any washing activity at the site. Sedimentation ponds used to clarify and recycle washwater back to the washplant will be constructed on the floor of the mine. Washwater will be recycled and not allowed to discharge off site. 8.0 ANNUAL REPORT This application serves as the Annual Report: As required the applicant shall annually submit to the council written estimates of: 8.1 The total area of the mineral extraction operation (expressed in acres) to be actively mined during the forthcoming year; The active mine area in 2023 will be approximately 5 acres and will include approximately 3.5 acres of current active mine area plus 1 to 1.5 acres of additional area to be mined in 2023. 8.2 The area under the permit (expressed in acres) which will not be actively mined during the forthcoming year.

Topographic information from Twin Cities Metro Region LiDAR data collected during the Spring and Fall of 2011. 2. Parcel information from Dakota County GIS data. 3. The floor of the mine area is anticipated to vary depending upon the ultimate soils balance available. Reclamation grades represent a minimum reclamation elevation. Clean fill, consisting exclusively of uncontaminated earthen materials, may be imported to the site as part of mine operations and used as backfill to attain a higher reclamation grade than is indicated on the plan. 4. Perimeter slopes will be backfilled to at least a 4:1 (H:V) slope. 5. Topsoil will be placed on backfilled and sloped areas to an average depth of 4-8 " and a minimum of 2". 6. Topsoiled areas will be seeded and mulched to establish vegetation and provide site stability. Seed mix will depend upon the nature of the reclamation soils but will be MnDOT general roadside mix 25-141 or similar.
