Aggregate Industries - Elk River Plant Conditional Use Permit Application for Mining - West Property Elk River, Minnesota Narrative Aggegate Industries (A.I.) is seeking approval fi.om the City of Elk River to permit 50-acres on the west property for sand and gravel mining. As depicted on the 2001 Operations Plan (attached), A.I. proposes to mine west from the Julius Nemeth property. The plan of action is to begin stripping the area of topsoil and overburden at the beginning of 2001 and then begin mining in early spring. Once approximately 50-acres is stripped and mined in this area, A.I. would relocate the sand and gravel wash plant from its present location onto this 50-acre site. The time fi.me for the move is scheduled for 2003-2004. Until the wash plant is.moved, all customer trucking will continue tO use the current plant entrance on the Julius Nemeth property. After the plant is relocated, the prefen-ed truck route will be onto 213th Street to U.S. Highway 169. This route will be subject to a safety review by the City and MNDOT and rnay require some alterations at the Highway 169 intersection. The reconstruction of Highway 33 may provide an additional truck route. The xvash plant at the new site will consist of the existing equipment ~vith some efficiency modifications. The settling ponds and recycling ponds will be relocated in the northwest comer of this 50-acre site. We will have to drill a new well, which will be similar to the existing.well in depth m~d capacity, depending on the requirements of a well permit. We will continue to recycle the wash water, using the new well for "make up" water. A berm will be constructed around the southeast comer of the new plant site to provide a visual and noise barrier for the residents to the south. The berm will average 15-feet in height, with some variations to provide visual appeal. It will be constructed with 3:1 slopes on the outside and 2:1 slopes on the inside. It will be seeded and the south side will be planted with a mixture of evergreen trees of various sizes. Refer to the attached Berm and Planting Plan. Ultimately mining will proceed to the south of this new Plant site onto the entire mineral bearing property owned by Aggregate Industries. The current plan is to mine the far south property (South of 33) after finishing the Nemeth property. Refer to the attached Overview Map for approximate mine phasing. This new plant site will accommodate all future mining activities by Aggregate Industries on its property west of U.S. Highway 169. The raw sand and gravel will be conveyed to this new plant site fi.O1T1 all future extraction sites. The conveyor route ~vill be established in the near future. The Enviromnental Impact Statement (EIS) anticipates that the finished grades in this part of the mining area will be sloping from east to west. The floor elevation for this 50-acre site will be higher than the EIS estimated, but will slope east to west. Refer to the attached Grading Plan.
