US Environmental Protection Agency. Region V and Wapora, Inc.. 1981. Final environmental impact statement : St. Croix Falls, Polk County, Wisconsin and Taylors Falls, Chisago County, Minnesota wastewater treatment systems. EPA-5-MN/WI-68-01-4612. US Environmental Protection Agency. Chicago, IL
An improved system to treat the wastewater generated by the residents of St. Croix Falls, Wisconsin, and Taylors Falls, Minnesota, is needed to comply with the Clean Water Act. The alternatives considered included upgrading/expanding the two existing facilities, combined treatment of the two communities' wastewater, and alternatives that would eliminate direct discharge of treated effluent to the St. Croix River. These alternatives consisted of various combinations of treatment processes, siting options, effluent disposal options, and sludge processing and disposal options. Implementation of any of tne alternatives would produce short-term construction impacts to the local environment. Few long-term operational impacts are anticipated. Based on the technical feasibility, cost-effectiveness, and environmental and socioeconomic concerns addressed in this filS, USEPA has concluded that the City of St. Croix Falls should upgrade and expand the existing wastewater treatment plant at St. Croix Falls and that the City of Taylors Falls should construct a new stabilization pond treatment system to replace the existing wastewater treatment facility at Taylors Falls.
