industrial processes and significant demolition, removal or remodeling of existing structures. Indicate the timing and duration of construction activities. The proposed project involves adding approximately 20 acres to an existing mining operation owned and operated by Tiller Corporation (Tiller). The project will allow the removal of a deposit of sand and gravel that will be processed into construction aggregates to serve the growing demand within the local area and the City of Elk River. Mining the additional twenty acres will improve overall end use grades for the area. Portions of the existing site have been in operation since the 1950’s. The existing operation, as well as several other operations in the vicinity, were the subject of an Elk River Mining District Environmental Impact Statement completed in June, 1994. Initially the subject parcel was included within the gravel mining district boundary, but was removed because it was not controlled by a mining operator at that time. Active mining will begin by stripping topsoil and overburden from the site using scrapers and dozers. Extraction of the aggregate deposit will be accomplished with loaders working from the floor of the existing mining operation. A primary crushing unit will be operated adjacent to the active face on the floor of the mining operation. Equipment will be placed to insure compliance with both daytime and nighttime noise standards. Material will be conveyed to Tiller’s main operations and stockpiling area located to the northwest of the subject parcel for further processing. Product stockpiling will also occur in the existing processing and operations area and all hauling of aggregates will occur from the main processing area. There will be no access to Proctor Road NW which abuts the subject property to the east, from the proposed expansion area during the mining operation. This project will not impact the number of trucks trips to and from the facility. Truck traffic is a function of demand. The project is expected to increase the overall life of the facility by approximately 5-10 years. The actual increase will depend upon market demand. c. Explain the project purpose; if the project will be carried out by a governmental unit, explain the need for the project and identify its beneficiaries. The purpose of the project is to provide aggregate material for use in various construction materials and projects throughout the northwestern metropolitan area. The aggregate produced from this site will be used for roads and buildings in both the public and private sectors. Aggregate from the site may be used in the construction of bituminous asphalt, ready-mix concrete, aggregate base, general fill and ice control. d. Are future stages of this development including development on any outlots planned or likely to happen? __Yes _X_No If yes, briefly describe future stages, relationship to present project, timeline and plans for environmental review. e. Is this project a subsequent stage of an earlier project? _X_Yes __No If yes, briefly describe the past development, timeline and any past environmental review. The subject property is adjacent to an existing mining facility owned and operated by Tiller. The existing operation as well as several other properties were the subject of an Elk River Mining District Environmental Impact Statement completed in June, 1994. Initially the subject parcel was included in the gravel mining district boundary, but was ultimately removed because it was not controlled by a mining operator. Portions of the existing operation have been active since the 1950’s. 7. Project magnitude data Total project acreage: 36.6 A (19.53 A of which will be actively mined.
