storm water ~nanagement system prior to being discharged into the Mississippi River at or below existing flow <br /> rates..,\ Storm Water Pollution Prevention Plan will be created and implemented as part of the improvements <br /> process. Temporary sediment and erosion control measures will utiltize various BMPs during the.construction of <br /> thc imprr)vements, and permanent features such as detention ponds and grassed swales will be used for flow rate <br /> control and water quality purposes. <br /> <br />b. Identify routes and receiving water bodies for runoff from the site; include major <br /> downstream water bodies as well as the immediate receiving waters. Estimate impact <br /> runoff on the quality of receiving waters. <br /> There is a system al:swales that transport runoff fi.om the north to south. The site runs offto the south and <br /> uttimatcly into the Mississippi River via the City's storm sewer system. There are no adverse impacts anticipated <br /> with the proposed development improvements. <br /> <br />a. Describe sources, composition and quantities of all sanita~, municipal and industrial <br /> wastewater produced or treated at the site. <br /> Thc source of wastewater from this project will be 686 homes. The composition of the w~te is t~ical residential <br /> wastewater. An estimate o f the amount of w~tewater produced is b~ed on a volume of 100 gallons per capita per <br /> day, 6:t6 homes, and an average of 2.75 people per home, which resulB in a volume of 188,650 gallons per day. No <br /> industrial wtmtewater will be produced at the site. <br /> <br />b, Describe waste treatment methods or pollutiofi prevention effo~s and give estimates <br /> of composition after treatment. Identify receiving waters, including major downstream <br /> water bodies, and estimate the discharge impact on the quality of receiving waters. If <br /> the ~roject involves on-site sewage systems, discuss the suitability of site conditions <br /> for such systems. <br /> No w~stcwatcr treatment will be done on site. Cu~ently, the City ofRamsey's sanit~y w~tewater is collected in <br /> interceI~tor sewers and treated by the Met Council's existing trea~ent faciliw in St. Paul. Sanit~y w~tewater ~om <br /> this project will also be treated by the Met Co~cil's existing Me~o m~icipal sewage ~eatment faciliW. The plant <br /> treats the w~tewater to MPCA standards and discharges the ~eated effluent to the Mississippi ~ver. <br /> <br />c. If wastes will be discharged into a publicly owned treatment facility, identify the facility, <br /> describe any pretreatment provisions and discuss the facility's ability to handle the <br /> volume and composition of wastes, identifying any ~mprovements necessa~. <br /> Wastewater fi.om this project will go to the existing Met Co~cil Metro trea~ent plant in St. Pa~, Minnesota. ~e <br /> existing plant h~ adequate capacity to se~ice the project, therefore no improvemen~ will be necess~. <br /> <br />d. If the project requires disposal of liquid animal manure, describe disposal technique <br /> and location and discuss capacity to handle the volume and composition of manure. <br /> Identify any improvements necessa~. Describe any required setbacks for land <br /> disposal systems. <br /> No animal wastes, except domestic pet w~te, will be produced on site. <br /> <br />a. Describe any of the following geologic site hazards to ground water and also identify <br /> them on the site map: sinkholes, shallow limestone formations or karst conditions. <br /> Describe measures to avoid or minimize environmental problems due to any of these <br /> hazards. <br /> <br />95 <br /> <br /> <br />
