The goal of this project is to develop the guidance needed for water quality parameter evaluation and calibration for Hydrological Simulation Program – FORTRAN (HSPF) applications that utilize the general water quality constituent routines on the land surface to generate loadings of nutrients and organic material for input to water bodies to support dissolved oxygen (DO), nutrient, and algal simulation.
This project supports activities by Minnesota Pollution Control (MPCA) Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting Total Maximum Daily Load (TMDL) studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
This project will provide an interpretive assessment of nitrogen concentrations in Minnesota rivers and streams, including spatial and temporal trends based on historical data sets. The trends analyses will provide information useful for evaluating nitrogen reduction efforts in the past couple of decades.
The study will assess existing phosphorus data records and create a model to explain phosphorus loading into the Red River of the North. Studies have found that the majority of nutrient loading in the stream located in agricultural areas occurs with sediment loading since nutrients are typically bound to sediment particles.
The goal of this work order is to make additions and enhancements to the Scenario Analysis Manager (SAM) tool best management practice (BMP) database and the methodologies used for the application of the BMPs.
This work will involve enhancing the capability of the Scenario Analysis Manager (SAM) tool to run more complex point source alternative scenarios, produce results and output in line with the recently developed Watershed Restoration and Protection Strategies (WRAPS) report standards, and general enhancements requested by users.
This work order will address the need for technical support and updates to the Scenario Analysis Manager (SAM) tool and PATH software based on training feedback. The trainings will include exercises focusing on improved and added functionality as well as the enhanced best management practice (BMP) database.
The contractor will collect and process the necessary files needed to develop a Processing Application Tool for HSPF (PATH) and Scenario Application Manager (SAM) project for 30 HUC 8 watersheds in Minnesota. SAM provides a graphical interface to the Hydrological Simulation Program FORTRAN (HSPF) model applications and expands the state’s investment in HSPF to a broader audience in support of the development of Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports.
The goal of this project is to develop forestry related best management practice (BMP) pollutant reduction/management efficiencies, costs, and management information applicable to Minnesota forests and incorporate these BMPs into the Hydrological Simulation Program FORTRAN (HSPF) model Scenario Application Manager (SAM) tool. By incorporating forestry BMPs into the existing SAM tool, forestry related management scenarios can be evaluated for potential impacts on surface waters and can inform the development of watershed restoration and protection strategies.
The goal of this work order is to enhance the Scenario Analysis Manager (SAM) support tool in order to represent best management practices in a more physically based manner, improve point scenario representation and analysis, and support MPCA with training in the application of the enhanced functionality.
The goal of this work order is to collect and process the watershed specific files needed to create the Scenario Application Manager (SAM) project files to apply the SAM software in selected major watersheds in Minnesota where an Hydrological Simulation Program – FORTRAN (HSPF) model has been developed. This work order will also involve technical support for the SAM users who are applying the SAM projects.
RESPEC will use the Processing Application Tool for HSPF (PATH) to construct the remaining 22 Scenario Application Manager (SAM) projects. SAM assists in understanding watershed conditions, and identifying priority areas and BMPs that will provide the greatest water-quality benefits for each dollar invested. The value of the tool is in its simplification of complex hydrologic and water quality model applications into transparent estimates of the significant pollutant sources in watershed.
The goal of this project is to provide three training sessions for the Scenario Analysis Manager (SAM) software and one training session for the Processing Application Tool for the Hydrologic Simulation Program FORTRAN (HSPF) model.
MPCA will administer funding to eligible Local Governmental Units to use MPCA-approved Advanced Inspectors to conduct work in accordance with Minn. Rules 7080, 7081, and 7083, which requires proper location, design, installation, use and maintenance of an individual subsurface sewage treatment system (SSTS) with a design flow of 2,500 gallons per day or more that protects the public health, safety, general welfare, and the environment by the discharge of adequately treated sewage to the groundwater. Multiple contracts will be awarded.
The overall goal of this process is to compile the information developed by the MPCA into summaries, tables, graphics and tools that the MPCA can use to replace sections of the Stormwater Manual. CDM Smith has developed an approach and workplan that is aimed at complimenting the knowledge of the MPCA and assisting the MPCA through supplemental literature searches, compilation of materials into usable formats, and facilitation of discussions when needed.

This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards. This management plan will also include implementation activities for reducing chloride to TCMA waters as well as identify high priority areas to target implementation activities.
