PERMIT APPLICATION TO THE CITY OF ELK RIVER APRIL 2023 Introduction I.� �I�Tf��L7U�TI��V Elk River Landfill, Inc. (ERL), a wholly owned subsidiary of Waste Management of Minnesota, Inc., owns and operates a mixed municipal solid waste (MSWj landfill (Landfill) under Minnesota Solid Waste Permit Number SW-74. The Landfill is located along U.S. TH 169 in the NW'/ of Section 3, T33N, R26W, and the SW'/ of Section 34, T34N, R26W, Sherburne County, Minnesota (see Figure 1). Besides the construction and demolition debris (C&D) landfill immediately and adjacent to the north of the Landfill, the remainder of the existing property owned by ERL provides a buffer surrounding the Landfill. The Landfill is permitted to accept MSW, C&D, yard waste for composting, industrial waste in accordance with a MPCA-approved Industrial Solid Waste Management Plan, and processing facility rejects. ERL maintains a Solid Waste Facility (SWF) license and conditional use permits in accordance with City of Elk River (the City or City) requirements. ERL and the City entered into an agreement on May 25, 2011 for the expansion of the facility into an area referred to as the southern development area (SDA). Based on the agreement, a Land Use Application was submitted to the City of Elk River dated June 27, 2011. Subsequently, the application and an amended Conditional Use Permit (CUP) was approved by the Elk River City Council on September 19, 2011. The SWF license references the amended CUP, and the two documents authorize construction and operation of the currently permitted facility. ERL is proposing to revise the CUP to incorporate approximately 20 additional acres of property, immediately to the south of the currently permitted landfill footprint. The additional 20 acres provides no additional MSW capacity, but instead will be used for improved stormwater management. Concurrent to the proposed CUP revision, ERL is proposing an ordinance amendment to Elk River Code, Chapter 30. Land Development Regulations, Article VI. Zoning, Division 10, Sec. 30-1834.(e) to allow for stormwater management features for the landfill to be located outside of the SWF solid waste facility overlay district boundary. A request for minor modification to the Landfill's MPCA Solid Waste permit (SW-74) will also be submitted to reflect the changes to the site grading and stormwater management features. 1.1 DESCRIPTION OF PROJECT The additional 20-acres of property has been purchased by ERL from Tiller Corporation, now part of Martin Marietta (Tiller). The property is currently used by Tiller for its gravel mining operation, as they retained mineral rights on the property per the terms of the purchase. As has been the practice at the existing Landfill, development of Landfill related components (in this case the proposed stormwater management infrastructure) will follow behind Tiller's mining operations. Tiller has an approved CUP from the City for their mining activity (including the 20-acre subject property). The additional property will allow for ERL to construct one large stormwater basin to replace the currently permitted design which included two sedimentation basins and would have required a lift station to manage stormwater from the Landfill. The modifications will allow for gravity drainage for stormwater �1 1.1
