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.
Varney Lake is owned and maintained by the City of white Bear Lake as part of its stormwater collection system. The City will excavate approximately 10,000 cubic yards of polycyclic aromatic hydrocarbons (PAH) contaminated sediment from Varney Lake (which is located in a residential portion of the City) and manage the sediments on site by encapsulating the sediment in a berm covered with clean top soil. The encapsulated sediment will be managed as a solid waste in what the MPCA refers to as a limited use solid waste landfill (Facility).
This project will compile and review previously conducted studies and will prioritize best management practices (BMPs) based on a cost-benefit analysis of their pollutant load reductions and life cycle costs. It will also support the design and construction of BMPs, such as rain gardens and infiltration practices, within the Villa Park subwatershed of the Lake McCarrons watershed.
This project will repair and upgrade the water control structure and provide water quality enhancement measures on Oasis Pond in Roseville, Minnesota. This project will also protect the quality of downstream receiving waters; specifically Lake Johanna, by reducing phosphorus pollutant loads.
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.
