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. The treated runoff from the site will enter the wetlands and ditches within the site, and into Trott Brook. The. wetlands and ditches ultimately empty into the Rum River, a tributary of the Mississippi River. Although the' volume of storm water entering the Rum River may increase, the rate at which it is discharged will not exceed current pre-developed rates. There are no adverse impacts anticipated with the proposed development improvements. -.~:- ~ . : , -~ t :,-' ........ *i"'- ...... :" '::'4 8 ~ ~ate~Qualtt -' waste~ate~ a. Describe sources, composition and quantities of all sanita~, municipal and industrial wastewater produced or treated at the site. Extension of the sewer main is required for this project. S~ita~ sewer will be installed with the internal streeB to provide semice to the development. The source of w.~tewater ~om this project will be 162 single family homes. The composition of the w~te is t~ical residential w~tewater. ~ estimate of the amour ofw~tewater produced is b~sed on a vol~e o f ] 00 gallons per capita per day, 162 single family homes, and ~ average of 2.75 people per home, which results in a volume of 44,550 gallons per day. No ind~tfial w~tewater will be produced at the site. b. Describe waste treatment methods or pollution prevention effo~s and give estimates of composition after treatment. Identify receiving waters, including major downstream water bodies, and estimate the discharge impact on the quality of receiving waters. the project involves on-site sewage systems, discuss the suitabilib of site conditions for such systems. No w~tewater treatment will be done on site. C~ent]y, the Ci~ ofRa~ey's s~ita~ w~tewater is collected in interceptor sewe~ and treated by the Met Co~cil's existing ~ea~ent facili~ in St. Paul. 8anit~ w~tewater Sore this project will also be treated by the Met Council's existing ~e~o municipal sew~e treatment facility. The pi,t treats the w~tewater to MPCA standards and discharges the ~eated effluent to the mississippi hver. c. If wastes will be discharged into a publicly owned treatment facility, identify the facility, describe any pretreatment provisions and discuss the facility's ability to handle the volume and composition of wastes, identi¢ing any improvements necessa~. W~tewater [rom this project will go to the existing Met Co~cil Me~o ~ea~ent plantin St. Paul. ~e e~sting pl~t h~ adequate capacity to se~ice the project, Serefore no improvemen~ will be necess~. d. If the pro]ect requires disposal of liquid animal manure, describe disposal technique and location and discuss capacity to handle the volume and Composition of manure. Identify any improvements necessa~. Describe any required setbacks for land disposal systems. No animal w~tes, except domestic pet w~te, will be produced on site. a. Describe any of the folloWing.geologic site hazards to ground water and also identify them on the site map: ~inkholeS,. shallow I'imestone formations or karst conditions. Describe measures to avoid or minimize environmental problems due to any of these hazards. "
