Shafer ME EXECUTIVE SUMMARY Planning Commission Meeting: December 16, 2019 Tentative City Council Meeting: January 21, 2020 AGENDA ITEM: 19-53-ME Renewal of the Shafer Contracting Co., Inc. Small Scale Mineral Extraction Permit for 2020 AGENDA SECTION: Public Hearing PREPARED BY: Kyle Klatt, Senior Planner AGENDA NO. 5.e. ATTACHMENTS: Site Location, Draft 2020 Mining Permit, Applicant Letter, 2019 Current Operations/Reclamation Status, 2020 Proposed Operations and Reclamation, Soil Testing Reports, Site Aerial (2018 and 2019) APPROVED BY: KL RECOMMENDED ACTION: Motion to recommend the City Council renew the Shafer Contracting Co., Inc. Small Scale Mineral Extraction Permit for 2020, subject to the terms and conditions in the attached Draft 2020 Conditions for Mineral Extraction. SUMMARY Applicant and property owner: Shafer Contracting, Co. Inc. Location: ¼ mile west of Rich Valley Blvd., 1 mile north of Bonaire Path East. Area in acres: 93 acre total area, approximately 15 acres active in the western 100 feet of Phase 4 and all of Phase 5. Comp Plan & Zoning: Agriculture Extraction progress: Phase 5 out of 7 (approximately 60% complete). Nature of request: Annual renewal The Planning Commission is being asked to consider a request from Shafer Contracting Company, Inc. to renew the existing Small Scale Mineral Extraction Permit for its operation located within the 12000 Block of County Road 71 (one mile north of Bonaire Path East along Rich Valley Blvd.) in the northeastern portion of Rosemount. Small Scale Mineral Extraction is permitted in the City as an Interim Use within specified areas, and the permit for such uses expires after one year. The Shafer site has been operating as a mine for several years, and the request for renewal is consistent with similar renewals that have previously been issued for the site. BACKGROUND Shafer has been extracting minerals from the site since 1998 and has owned the property since 2000. No sand or gravel was removed in 2019, and there was a limited amount of haul-back and recycled material brought to the property over the past year. The amount of activity projected for 2020 is dependent on future construction projects. Shafer continues to bid on projects, and there is the potential for projects that would necessitate the removal of approximately 50,000 cubic yards of sand. Shafer would continue removing aggregate from Phase 5 as identified on the 2020 Proposed Operations and Reclamation Plan and depositing haul back material in the middle 500 feet of phases 2, 3, and 4. Haul 2 back operations have a low elevation of about 850 feet in phases 3 and 4, and progress up to an 875 elevation in phase 2. In 2006, the City Council approved the haul back operation if it complied with the following standards: from a MnDOT construction project, is clean fill material, does not contain organic matter, and meets a 95% compaction threshold. Shafer previously submitted test results for the haul back material through 2015, but in recent years has asked to delay the compaction testing due to the limited amount of haul-back material brought into the site since 2015. No such material was deposited on this site in 2018 and a limited amount of haul-back and recycled concrete material was deposited in the mine in 2019. In accordance with previous requirements, Shafer did complete environmental testing in November; however, some of the fill material failed the compaction test (less than 95% compaction threshold). Shafer will need to correct these specific areas, update the field density test reports when this work is complete, and should continue to perform testing on all material brought into the mine. It is recognized staff hasn’t always required testing of haulback material since the amount was minimal. However, since there has been a failed compaction test, the applicant must bring that material into compliance as part of the 2020 mining permit. Since the applicant is predicting limited haul-back in 2020, staff is anticipating the applicant may again request a delay in testing of new material, which has been the case the past couple years. 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. Police records found no incidents at the subject property during 2019. CONCLUSION & RECOMMENDATION The site has received had very little mining activity over the last several years. The issue of mining and haulback is addressed in the IUP conditions and the need for some soil correction and compaction retesting is addressed via one of the conditions. At this time, staff recommends renewal of the Small Scale Mineral Extraction Permit at the Shafer Contracting Co. Inc., mine for 2020.
