<br />I <br />I. <br />I <br />I' <br />I <br />I <br />I <br />I <br />I <br />Ie <br />I <br />I <br />I <br />I <br />I <br />I <br />I. <br />I <br />I <br /> <br />All erosion control measures shall be installed prior to grading operations and maintained <br />until all disturbed areas have been restored. Streets will be swept as necessary where <br />construction sediment has been deposited. Also, NURP ponds must be constructed before <br />main grading. After construction, all disturbed areas will be either paved or vegetated to <br />eliminate exposed soil surfaces. Removal of erosion control measures will not occur until <br />all disturbed areas have been stabilized. <br /> <br />17. WATER QUALITY - SURFACE WATER RUNOFF <br /> <br />EAW: <br /> <br />A. COMPARE THE QUANTITY AND QUALITY OF SITE RUNOFF BEFORE AND <br />AFTER THE PROJECT. DESCRIBE METHODS TO BE USED TO MANAGE <br />AND/OR TREAT RUNOFF. <br /> <br />B. IDENTIFY THE ROUTE(S) AND RECENING WATER BODIES FOR RUNOFF <br />FROM THE SITE. ESTIMATE THE IMPACT OF THE RUNOFF ON THE QUALITY <br />OF THE RECENING WATERS. <br /> <br />AUAR: <br />For an AUAR, the following additional guidance should befollowed in addition to that in <br />the "EA W Guidelines. " <br /> <br />. <br /> <br />It is expected that an AUAR will have a detailed analysis of storm water issues. <br /> <br />. <br /> <br />A map of the proposed storm water management system and of the water bodies that <br />will receive storm water should be provided. <br /> <br />The description of the storm water management should identifY on-site and "regional" <br />detention ponding and also indicate whether the various ponds will be new water <br />bodies or converted existing ponds or wetlands. Where on-site ponds will be used but <br />have not yet been designed, the discussion should indicate the design standards that will <br />be followed. <br /> <br />. <br /> <br />If present in or adjoining the A UAR area, the following types of water bodies must be <br />given special analyses: <br /> <br />Lakes: Within the Twin Cities metro area a nutrient budget analysis must be <br />prepared JiJr any "priority lake" identified by the Metropolitan Council (see <br />Appendix E of "}''A W Guidelines" (1990) or contact the Council stafJ). Outside of <br />the metro area, lakes needing a nutrient budget analysis must be determined by <br />consultation with MPCA and DNR staIJs; <br /> <br />Trout streams: If storm water discharges will enter or aIJect a trout stream, an <br />evaluation of the impacts on the chemical composition and temperature regime of <br />the stream and the consequent impacts on the trout population (and other species <br />of concern) must be included. <br /> <br />Guidant Campus Master Plan <br />Final AUAR and Mitigation Plan <br /> <br />- 20- <br /> <br />January 2003 <br />
