Superfund staff will assist in the project by providing oversight of contractual requirements and provide technical assistance as needed.
This project will support updates to the Draft Bald Eagle Lake TMDL. The updates will address comments received during the public comment period. The comments resulted in the development of individual Wasteload Allocations for stormwater sources in the Bald Eagle Lake watershed.
On behalf of the Metropolitan Council, Environmental Financial Group Inc. generated a matrix of water conservation programs with detailed information about the costs and benefits of the programs. Tools were also developed to allow users to calculate potential water savings, estimate program implementation costs, and test the effects of various water conservation programs and rate structures.
This project will complete a Watershed Restoration and Protection Plan for the Lower St. Croix River that provides quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for all impairments within the watershed, and that are understood and adoptable by local units of government and other stakeholders.
This project will complete a pollutant source identification and subwatershed information report and support the development of a Draft Restoration and Protection Plan (RAPP). It will also support the devlopment of a Implementation Plan that will identify target areas for BMP implementation for bacteria reductions.
On behalf of the Metropolitan Council, Barr Engineering Company developed maps and supporting information to characterize the relationship between surface waters and groundwater, identifying surface waters most likely to be impacted by groundwater withdrawals in the region. This project also provided guidance on effective resource monitoring strategies and costs for each type of surface water feature.
The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. The Metropolitan Council, in conjunction with S.E.H. consultants, evaluated water supply approaches to serve the northeastern part of the Twin Cities metropolitan area. A subregional study areas was selected based on the indication of potential problems with the long-term sustainability of current water supplies, as well as expressed interest by community stakeholders.
The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. Three projects are underway to identify the advantages and disadvantages of combining water supply systems, using new water supply sources such as treated water from Saint Paul Regional Water Services or raw water from the Mississippi or St. Croix rivers, and optimizing groundwater pumping to protect water levels in White Bear Lake and other lakes across the northeast metro.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
The Metropolitan Council, in conjunction with HDR Engineering, Inc. consultants, will evaluate a variety of approaches to develop sustainable water supplies across the metro area. Subregional study areas are being selected where multiple communities face potential problems with the long-term sustainability of current water supplies, and where community stakeholders have expressed interest in learning more about sustainable water supply options.
As the Metropolitan Council updated the Twin Cities Metropolitan Area Master Water Supply Plan, stakeholders asked the Council to consider the sustainable limits of the region’s water sources. The Council’s most important analytical tool is a regional groundwater flow model (Metro Model 3), which can be used to quantify the long-term regional impacts caused by hundreds of independent groundwater appropriations.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. 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 project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
This project will provide modeling services to support the completion of the Typo Lake and Martin Lake Excess Nutrients TMDL report. A Total Maximum Daily Load (TMDL) report quantifies pollutant levels, identifies sources of pollution, and proposes ways to bring water quality back to an acceptable level.
State law charges the Metropolitan Council (Council) with developing and maintaining a base of technical information needed for sound water supply decisions (Minnesota Statutes 473.1565). The Council’s primary tool to provide this information is the Metro Model 2, a regional groundwater model capable of predicting the impacts of planned water demand on aquifers and connected lakes and streams. The Metro Model 2 is a modern and comprehensive groundwater model of the Twin Cities area, but it is currently out-of-date.
Regional recharge modeling with the Twin Cities daily soil water balance (SWB) model has been a fundamental part of the Metropolitan Council’s groundwater flow modeling effort and supports the Metropolitan Area Master Water Supply Plan. The SWB model is used to evaluate the impact of planned and potential land use and climate on recharge in the eleven-county metropolitan area, and supports the ongoing update of the regional groundwater flow model.
This project will develop a watershed restoration plan that provides quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for all impairments within the watershed. It will also an important framework for civic and citizen engagement and communication, which will contribute to long-term public participation in surface water protection and restoration activities throughout the watershed.
Within the Valley Branch Watershed District (VBWD), there 47 Minnesota Department of Natural Resoruces (MN DNR)-protected basins with surface areas larger than 10 acres and three DNR-protected streams. Only Sunfish Lake is currently on MPCA’s 303(d) Impaired Waters List for aquatic recreation due to excessive nutrients. However, Bay Lake, Eagle Point Lake, Downs Lake, Goose Lake, Kramer Pond, and Echo Lake are on the draft 2012 Minnesota 303(d) Impaired Waters List for aquatic recreation due to excessive nutrients, and Kelle’s Coulee is on the draft 2012 list due to bacteria.
The Metropolitan Council, in conjunction with CDM Smith consultants, undertook a project to collect and disseminate data regarding water costs and conservation programs in the seven-county metropolitan area, including:
• Evaluating all water rate structures of the communities in the seven-county metro area. The information on rates by community is correlated with community per capita values, peaking ratios, and other water use characteristics.
• Evaluating all water conservation programs in the communities in the seven-county metro area.
The Metropolitan Council, in conjunction with CDM Smith and HKGi consultants, reorganized and expanded the water conservation tools on the water supply planning pages of the Metropolitan Council’s website. The revised toolbox was organized into an online, web-based guide format. These tools are supplemented with fact sheets and case studies that serve to educate and provide useful information to support water conservation programs and activities.
