Statutory Authority: MS s 103G.315; 105.415 History: 8 SR 533; L 1985 c 172 s 80; L 1985 1Sp16 art 2 s 19; 25 SR 143; 27 SR 529 Published Electronically: June 11, 2008 6115.0201 SPECIFIC STANDARDS; EXCAVATION. Subpart 1. In general. In addition to compliance with the general standards in part 6115.0200, subparts 2 to 5, specific requirements shall be met for the activities described in subparts 2 to 7. Subp. 2. Excavations for beach development. The existing site conditions will not provide a suitable beach using a sand blanket alone. When the proposal includes the installation of a beach sand blanket, the area to be excavated shall be consistent with the criteria for filling under part 6115.0190, subparts 2 to 5. The depth of excavation needed to reach a suitable beach stratum shall be the minimum depth necessary considering anticipated site maintenance and reasonable water depths for a beach. Subp. 3. Waterbasin excavations. Excavations for improvement or enhancement of hydrologic and biologic conditions in all, or large portions of waterbasins: A. A public need for the excavation has been established by local governmental resolution specifying the public interests to be improved or enhanced, except where the project is state sponsored. B. The proposed project is intended to achieve one or more of the following public purposes: (1) to improve navigation, swimming, and other recreational uses; (2) to reduce winter fish -kill potential; (3) sediment removal to eliminate a source of nutrients and/or contaminants. C. The proposed excavation is part of an overall improvement or enhancement project based upon adequate background and field test data for which a comprehensive plan is submitted at the time of application detailing all of the following: (1) Objectives to be accomplished, and an analysis of any alternative means considered to meet the objectives and the rationale for selecting excavation. (2) Sufficient soil boring and bottom sampling data to evaluate sediment quality and bottom "seal" conditions. Where excavation is proposed on a waterbasin that is perched on an impervious stratum, soil borings must show that the proposed excavation will not rupture the impervious stratum.
