b. Give a complete description of the proposed project and related new construction. Attach additional sheets as necessary. Emphasize construction, operation methods and features that will cause physical manipulation of the environment or will produce wastes. Include modifications to existing equipment or industrial processes and significant demolition, removal or remodeling of existing structures. Indicate the timing and duration of construction activities. 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 proposed project involves adding approximately 30.6 acres to an existing mining operation ovmed and operated by Plaisted Companies (Plaisted). Approximately 9.5 acres of the property v~~ill be used for buffer along highway/street rights-of--way and neighboring properties. Buffer areas will not be mined and vegetative screening will be maintained. 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 azea will improve overall end use grades for the Plaisted operation. Portions of the existing site have been in operation since the 1980'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 misting 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 nvning operation. Equipment will be placed to insure compliance with both daytime and nighttime noise standards. Material will be conveyed to Plaisted's main operations and stockpiling azea located to the south 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 213 Ave NW or Highway 169 which abut the subject property to the north and east, respectively, 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. d. Are future stages of this development including development on any other property 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 Plaisted. 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 1980's. 7.
