Borrow Pit Reclamation Protocol. APPROVED BY: Dili RECOMMENDED ACTION: Motion to approve the 2009 Mineral Extraction Permit for Danner, Inc. with conditions. 4 ROSEMOUNT CITY COUNCIL City Council Meeting: October 21, 2008 EXECUTIVE SUMMARY ISSUE The applicant, Marlon Danner of Danner, Inc. owns and operates a gravel mine at 4594 145' Street East. Danner has requested the annual renewal of their mineral extraction permit for 2009 and a modification to mineral extraction permit's reclamation plan to grade the entire site for development after mining activities have ceased. September 23 Planning Commission Meeting The Planning Commission conducted a public hearing for the mineral extraction permit during their September 23 meeting. No one spoke during the public hearing and the Planning Commission had no comments concerning Danner's request. The Planning Commission recommended the approval of the mineral extraction permit with staff's recommendation with a 4 -0 vote. BACKGROUND Applicant Property Owner(s): Location: Area: Comp. Guide Plan Design: Current Zoning: Marlon L. Danner of Danner, Inc. 4594 145` Street East one mile east of US Highway 52 and one quarter mile south of CSAH 42 75 Acres IM Industrial /Mixed Use and AG Agriculture AG Agriculture Danner owns a 75 acre property located directly south of County Road 42 and approximately one mile east of US Highway 52. The gravel mine is operated only on the southern half of the property with the north half of the property currently being farmed. Danner's mining vehicles share a joint access with the Solberg operation to the east. The access road is located on the Danner and Otto Ped property line. Danner anticipates that his property will be developed after the gravel mine has finished operation and the new County Road 42 and US Highway 52 intersection is constructed. The existing reclamation plan shows the finish grades for the south half of the property that is being mined, but no changes in grades are shown for the northern half of the property. Danner requests a modification of the mineral extraction permit to regrade the northern half of the property to complement the south half of the property and prepare it for it future development. Annual Renewal Danner operated within Phase 1 and the eastern half Phase 2 during 2008. The operation has reached the southern limits of the property for Phase 1. It is anticipated that during 2009 Danner will remove the berm on the east side of the mine which will daylight the property with the completed phases of the Solberg operation on the Otto Ped property to the east. Danner will also work within Phase 2 heading west towards Phase 3. Danner will be expected to reclaim Phase 1 in the fall 2009 or spring of 2010, including placing top soil and seeding all areas except those that truck traffic and mining equipment would be driving on. Staff is supportive of the annual renewal to allowing mining activity in the eastern half of Phase 1 and all of Phase 2. This recommendation is subject to the conditions outlined in the attached Mineral Extraction Permit. In addition to these specific conditions, all mineral extraction permits are subject to the general performance standards outlined in Section 11 -10 -4 of the zoning ordinance. Mineral Extraction Permit Modification Danner's mineral extraction permit allows the mining of gravel from the southern half of the property where a glacial moraine exists. Mining is not permitted on the northern half of the property. The existing reclamation plan provides a relatively flat grade on the southern half of the property with a 1.5% slope to the north to provide drainage. The northern half of the property is not changed in the existing reclamation plan. The northern half of the Danner property has a gentle slope from the south to the north resulting in a 16 foot drop from the 860 foot elevation at the mining boundary to the 844 elevation in the ditch on the south side of County Road 42. For reference, County Road 42 in front of the Danner property is at an 850 foot elevation. Danner is requesting to regrade and reclaim the northern half of the property to carry the 1.5% slope from the southern half of the property through the northern half of the property. This would result in a rising of the northern boundary of the property to the 852 elevation, which is approximately an eight foot rise in elevation, but only two feet higher than County Road 42. To accomplish this regrading, Danner proposes to bring in fill material from various municipal construction jobs that Danner work at. The material would be tested using a protocol developed by Pioneer Engineering before it is brought into the site to ensure that it is clean and appropriate fill free from contamination. Danner is proposing to regrade the property in three phases from south to north to minimize any impacts by erosion or dust. The regrading would occur by first scraping off the top soil and piling it on the north side of the phase, seeding the pile of top soil, then bringing in and compacting the fill material, and finally returning the top soil and seeding or farming the site. Then, Danner would move to the next phase and repeat the process until the enter site has been regraded and reclaimed. No mining of gravel from the north half of the site will be allowed during this process. RECOMMENDATION Staff is supportive of Danner's request and the Planning Commission has recommended approval.

BORROW PIT RECLAMATION PROTOCOL ROSEMOUNT, MINNESOTA OVERVIEW Danner Inc. is currently mining granular materials from the property at 4594 145 Street, and has submitted plans and details to the City of Rosemount specifying final or bottom elevation for the completed pit. Danner Inc recognizes that the City requires reclamation of the property, and sees merit in initiating this process such that the mining equipment can also be used to place "haul- back" earth materials in a controlled fashion over time. The materials that will be used to refill the borrow area will be restricted to soils taken from projects from local Municipalities. Materials taken from these projects have an excellent historical record of being free from "contamination or hazardous" materials and therefore are ideally suited for the reclamation process. Given these conditions, Danner Inc desires to use "haul- back" materials from projects from local Municipalities as controlled fill to accommodate future light commercial construction. Protocol Guiding Principles Danner Inc.'s protocol involves the ongoing reclamation of the borrow pit with the end goal of creating prepared building pads for light commercial construction. To the end, the guiding principles included in the protocol presented to the City include the following: 1) All offsite fill materials will be evaluated for the presence of "contamination or hazardous which would be unacceptable to the City. 2) No offsite fill materials will be include debris, refuse or other deleterious materials, which would be unacceptable to the City. 3) Organic soil will only be acceptable for designated berms or green areas. 4) Earth materials used as controlled fill will be comprised of soil types that lend themselves to the development of a normal moisture- density relationship for compaction. 5) Danner Inc. recognizes that some conditioning of the haul -back soils may be required to facilitate compaction. a) The size of the borrow facility permits placing materials in thin lifts for aeration and compaction purposes. Description Method of Test Standard Frequency Action Required (If failure) Standard Proctor moisture density test ASTM D698 Test required in conjunction with field density test for determination of compaction levels 1 per soil type N/A Particle size analysis ASTM: D422 Test required to document if certain soils are moisture sensitive or will not develop normal moisture density relationship 1 per source or change in soil type If soil tests as being moisture sensitive, materials will be restricted to non structural areas 6) Danner Inc. will coordinate Braun Exc. Services to obtain environmental screening and Standard Proctor samples prior to hauling any earthen materials to the site. a) Once approved for fill placement, Danner Inc. will coordinate for site observations and compaction tests at representative intervals during the reclamation operations. 7) Based on plans submitted to the City, fill thickness will approach 4 -8 feet. a) The reclamation protocol will include additional site geotechnical evaluation of the completed fill sequence through the placement of soil borings or electric piezocone soundings. b) This additional parcel specific information will be utilized to develop foundation plans /recommendations for commercial building purposes. Quality Assurance Fill Material Control 1) Danner Inc. will retain Braun Intertech to perform acceptance testing of haul -back material proposed for use in the borrow area. a) Representatives of Braun Intertech will sample and perform screening tests on proposed fill materials in accordance with their letter. b) Danner Inc. will provide Braun Intertech with source of imported materials and contact name of their representatives at that location to coordinate the screening activities. 2) In addition to environmental tests, the following pre qualification testing will be performed for each soil type: 3) Braun Intertech will verbally advise owner of any material that fails screening for contamination or hazardous materials, or will no produce a normal moisture density relationship for compaction. 4) Braun Intertech will provide soil test reports within three working days of testing for routine soil types. Some environmental screening may require longer lead times. Quality Control Filling Placement Requirements 1) Prior to any filling operations, Danner Inc. will coordinate with Braun Intertech that materials being transferred to the site are free of contamination and/or hazardous materials, and these materials have been tested for optimum moisture density relationship and gradation. a. Danner Inc. will restrict earth materials to those free of debris, rubbish, frozen clumps, free of cobbles and boulders over 10" in diameter, organic soils, vegetation, or other materials. i. Organic materials will be stockpiled for utilization on embankments and organic slopes, as detailed in the plans submitted to the City. 2) Danner Inc. will perform all fill, backfill, and compaction in accordance with the recommendations of the reclamation protocol. a. The bottom elevation of the borrow pit or the various fill layers should be graded such that standing water does not occur. b. Fill surfaces should be maintained to keep areas free of water during placement and compaction c. Danner Inc. will not place backfill or fill materials on surfaces that are muddy, frozen, or that contain frost or ice. 3) Danner Inc. will only use fill materials with moisture contents near optimum (OMC) based on the Standard Proctor moisture density relationship test. a. Fill materials shall be conditioned, either dried or water added, in order to obtain moisture level near optimum. b. Danner Inc. will correct and soft or unstable areas by scarifying, wetting or drying and then subjecting to surface compaction procedures Compaction Requirements 1. Danner Inc. will not allow loose fill layers to exceed 1 foot in thickness. 2. Danner Inc. will utilize skilled work persons and proper equipment in good working condition to perform the work to full completion in a satisfactory manner. 3. Fill compaction will meet the following requirements: Item Description Method of Test (Standard Proctor) Minimum of Maximum Dry Minimum No. of Tests per Unit Area General Building pad area Structural areas beneath the building pad including a 1.1 oversize zone extending beyond the ASTM: D698 98% 1 per 2000 cubic yards or every 54,000 sq ft per lift Non- building pad areas External non structural areas above/outside the 1.1 zone ASTM: D698 95% 1 per 2000 cubic yards or every 54,000 sq ft per lift Lawn or unpaved areas In embankments or green areas ASTM: D698 90% 1 per 2000 cubic yards or every 54,000 sq ft per lift 4) Fill materials that have been placed but found to be below specified density, shall be subjected to additional compaction and testing until the fill meets or exceeds specified density. Field Quality Control Coordination 1. Danner Inc. will notify Braun Intertech prior to the initiation of any control fill placement so independent testing laboratory can document that sub grade surface is acceptable for fill placement. 2. Danner Inc. will arrange for Braun Intertech to perform compaction testing as placement occurs. a. Tests will be performed to the frequencies required per lift. 3. Danner Inc. will provide elevation and location control on site so independent testing laboratory can properly locate its tests and retests, as required. 4. Danner Inc. will perform surveys on an ongoing basis or as a minimum at the end of every year's fill placement to develop as -built documents for submission to the City. 5. Filling operations will not be performed during the winter months. a. Fill materials can be stockpiled, at designated areas on sit, for fill placement when weather conditions are appropriate.
