sto~ water management 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 />the improvements, 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 of swales that transport runoff from the north to south. The site runs offto the south and <br /> ultimately 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~j m~Jcipal and industrial <br /> wastewater produced or treated at the site. <br /> -the source of wastcwater from this project will be 686 homes. ~e composition of the w~te is t~ical residential <br /> wmstewater. An estimate o[' the amo~t of w~tewater produced is b~ed on a reline of 100 gallons per capita per <br /> day, 6:~6 homes, and an average of 2.75 people per home, which msul~ in a volume of 188,650 g~lons per day. No <br /> ind,.retrial ,~tewaer will be produced at the site. <br /> <br /> b. Describe waste treatment methods or pollution prevention effo~s and give estimatek <br /> of comOosition a~er treatment. Identify receiving watem,, including majo(downstream <br /> water bodies, and estimate the discharge impact on the quality of receiving waters. If <br /> the project involves on-site sewage systems, discuss the suitability, of site conditions <br /> for such systems. <br /> No wxstewater treatment will be done on site. Cu~ently, the City ofR~ey's sani~ w~tewater is collected in · <br /> interceptor sewem and treated by the Met Council's e~sting trea~ent faciliw in St. Paul. S~it~ w~tewater ~om <br /> this prnject will also be treated by the Met Co~cil's e~sting Me~o m~icipal sew~e ~eatment faciliW. The plant <br /> treats dm w~tewater to MPCA standar~ ~d discharges the treated e~uent to the Mi~issippi ~ver. <br /> <br />c. If wastes will be discharged into a publicly owne~ treatment facility, identi~ the facility, <br /> describe any pretreatment provisions and discuss the f~dliys ability to handle tho <br /> volume and composition of wastes, identifying any improvements necessa~. <br /> Wastewater ~om ~is project will go to the existing Met Council Metro ~ea~ent pl~t in St. Pa~ Mi~esota. ~e <br /> ex/sting pl~t h~ Mequate capacity to se~ce the project, therefore no improvemenB will be necess~. <br /> <br />0. If the 9reject requires disposal of liquid animal manure, describe disposal technique <br /> and location and discuss capaciW 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 w~stes, except domestic pet w~te, will be produced on site. <br /> <br />a. Describe an? 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 />-427- <br /> <br /> <br />
