The St. Cloud Waste Water Treatment Facility (SCWWTF) is currently conducting long term planning for future biosolids management. The most likely path forward includes dewatering of the digested biosolids, which will produce a supernatant stream with significant phosphorus and ammonia loads that would be returned to the liquids treatment portion of the WWTF. Returning these nutrient loads to the liquids train would result in increases to effluent concentrations, increases in power consumption, or both.
This project will reduce nutrient loadings to Sand Creek from the neighborhoods which are the greatest contributors. Project activities include the installation of a new stormwater pond and a network of 10 strategically-placed curb-cut rain gardens.
The primary goal of this project is to train the Minnesota Pollution Control Agency staff in Hydrologic Simulation Program FORTRAN (HSPF) model calibration of nutrients, oxygen demand, and algal processes and in MATLAB script development for model output processing and report generation. Additionally, a pilot application process will be developed to link HSPF applications to Water quality Analysis Simulation Program (WASP) to take advantage of the advanced sediment oxygen demand processes.
LEQA is a Minnesota Department of Agriculture (MDA) program to help livestock producers address, using a non-regulatory approach, the unique water quality issues on their farms. The MDA has contracted with Ag Resource Strategies, LLC, to recruit farmers to enroll in the LEQA program. The company trains technicians to assess different areas of each farms, such as the farmstead, livestock facilities, fields and wooded areas. The technicians then develop an environmental assessment and identify financial assistance for these projects.
This project will produce a Winter Maintenance Assessment tool prototype that allows users to create a customized approach to modify their existing winter maintenance program that will reduce their road salt use. The tool will allow users to take inventory of their current practices and evaluate how they are doing today and where they have the most potential to reduce salt usage.
