16. 17. 18. This item does not need to be addressed because the action proposed in this A UAR does not include or adjoin recreational water bodies. Erosion and sedimentation The number of acres to be graded and number of cubic yards of soil to be moved need not be given; instead, a general discussion of the likely earthmoving needs for development of the area should be given, with an emphasis on unusual or problem areas. In discussing mitigation measures, both the standard requirements of the local ordinances and any special measures that would be added for A UAR purposes should be included. Not applicable. Water Ouality-stormwater runoff a. Compare the quantity and quality of site runoff before and after the project. Describe permanent controls to manage or treat runoff. Describe any stormwater pollution prevention plans. b. Identify routes and receiving water bodies for runoff from the site; include major downstream water bodies as well as the immediate receiving waters. Estimate impact runoff on the quality of receiving water. For an A UAR the following additional guidance should be follozoed in addition to that in "EA W Guidelines': -it is expected that an A UAR will have a detailed analysis of stormwater issues; -a map of the proposed stormwater management system and of the water bodies that will receive stormwater should be provided; -the description of the stormzoater systems would identiJ~d on-site and "regional" detention ponding and also indicate whether the various ponds zoiI1 be new water bodies or converted existing ponds or wetlands. Where on-site ponds will be used but have not yet been designed, the discussion should indicate the design standards that will be followed. -if present in or adjoining the A UAR area, the following types of water bodies must be given special analyses: -lakes: within the Twin Cities metro area a nutrient budget analysis must be prepared for any "priority lake" identified by the Metropolitan Council. Outside of the metro area, lakes needing a nutrient budget analysis must be determined by consultation zoith the MPCA and DNR staffs; -trout streams: if stormwater discharges will enter or affect a trout stream an evaluation of the impacts on the chemical composition and temperature regime of the stream and the consequent impacts on the trout population (and other species of concern) must be included. Not applicable. Water Quality-Wastewater a. Describe sources, composition and quantities of all sanitary, municipal and industrial wastewater produced or treated at the site. b. Describe waste treatment methods or pollution prevention efforts and give estimates of composition after treatment. IdentiJ~d receiving waters, including major downstream RAMSEY TH 10 CORRIDOR AUAR 15
