Peer Engineering, Inc. (Peer) will evaluate and recommend to MPCA groundwater monitoring staff prospective sites/locations for the installation of groundwater monitoring wells to evaluate contaminant/pollutant concentrations from various sources. Peer will oversee the installation of monitoring wells by retaining a state drilling contractor or preparing bid documents to retain well driller through the Department of Administration. Superfund staff will assist in the project by providing oversight of contractual requirements and provide technical assistance as needed.
This first year of the project will collect available data relevant to the TMDL development, determine the data sets best suited for the TMDL development. Gain a better understanding of the watershed and impaired lakes, and assessment of all potential sources (internal and external) of the causes of lake impairment. EOR will also review the data produced by the MPCA for the impairment assessment for each of the lakes during year 1 of the project.
This project will construct three watershed framework models built using the Hydrologic Simulation Program FORTRAN. These executable models will simulate hydrology at the 12-digit HUC subbasin scale. An HSPF model will be built for each of the following 8-HUC watersheds: Red Lake River (09020303) and the Clearwater River (09020305).
This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
This project will continue to develop, and calibrate/validate the hydrology of an HSPF watershed model for the Thief River watershed. The consultant will add representation of point source discharges to the model. The consultant will compile flow data for the purposes of calibration and validation. An initial hydrologic calibration will be performed and submitted for approval. The consultant will produce an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs.
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
This project will complete the final Implementation Plan, semi-annual and final reports and hold project meetings. The Implementation Plan will identify target areas and priorities for implementation strategies to improve water quality for Bluff Creek. This project will build the groundwork so Bluff Creek will meet water quality standards for aquatic life in the future.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
