devices such as tree protection fence, perimeter silt fence, rock construction entrances, construction phasing, and timely stabilization of disturbed surfaces. The MPCA, the Rice Creek Watershed District, and the Cities of Roseville and Arden Hills will have final approval of all details pertaining to erosion control procedures. Because the Projects will be monitored through the entire construction process, the adverse effects fram erosion and sedimentation should be minimized. 17. Water quality: surface water 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. The proposed improvements will increase the amount of impervious surjace on the campus, which will increase the arnount of site runoff. The Storm Water Management Plan for the campus suggests several mitigation rneasures, including the construction of permanent best management practices (BMP) designed for water quantity control and quality treatment. These BMPs will be designed in accordance with the MPCA NPDES General Stormwater Discharge Permit, Rice Creek Watershed District Permit, and the ordinances of the Cities of Roseville and Arden Hills and will be incorporated into development projects on campus as they are constructed. These permits and ordinances require storm water basins with a permanent pool for water quuliry treatment and a temporary pool for water guantity control. The temporary pool is used to reduce proposed peak runoff rates for critical storm events. The Rice Creek Watershed District also reguires runoff volume reduction BMPs be included with every project. The permanent BMPs that will be utilized to meet the above criteria could include storm water basins, infiltration basins, ditches/swales, green roofs, pervious pavements, and structural devices to treat and control runoff discharging from the project area. Each stage of development will meet the regulatory standards in place at the time orbuildzng permit application. All stages of development will recognize the others to ensure that a comprehensive storm water management plan is constructed for the site. Also, the College will work towards ensuring that all direct, untreated discharges to Lake Johanna and Little Lake Johanna are eliminated once the campus expansion is complete. 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 waters. Storm water runoff is conveyed to hvo lakes adjacent to campus, Lake Johanna and Little Lake Johanna. These lakes discharge into a county ditch that flows north towards Rice Creek, which ultimately discharges into the Mississippi River. As stated above, permanent BMPs will be constructed to address additiona! runoffgenerated from the project area. These measures will provide the proper treatment and rate control to minimize potential impacts to the downstream receiving water. Please see the Storm Water Management Study attached to Attachment 7, the PUD Report, completed by the College in 2007 for more detail. 18. Water quality: wastewaters a. Describe sources, composition and quantities of all sanitary, municipal and industrial wastewater produced or treated at the site. The sources and composition of wastewaler- inclarde standard ma�nicipal waste. Ba.red on sewer usage data_from 2005 and 2006, the average monthly setiver usage is approximately 1,793,486 gullons.
