The City of Darwin is applying for a construction loan under the Minnesota Department of Health (MDH) drinking water revolving fund program and is, therefore, subject to the state environmental review process. This notice is to advise the public that MDH staff has reviewed the proposed project and has determined that preparing an Environmental Assessment Worksheet is not required.
The loan applicant has solicited public comment on potential environmental consequences. After reviewing any comments received we conclude that construction and project implementation will lead to no significant environmental impact.

II. Present Water System and Need
The City of Darwin utilizes groundwater to supply water to the city’s municipal water system. The system consists of two wells with a capacity of 130 gallons per minute each. These wells contain iron, manganese and an elevated level of arsenic that exceeds the maximum contaminant level of 10 mg/l. Well # 1 has an arsenic concentration averaging 27 mg/l and well #2 averages 18 mg/l The water systems elevated storage capacity is 50,000 gallons. Water is filtered by two pressure filters containing media of unknown age, This filtered water occasionally exceeds the maximum contaminant level for arsenic. Tile system also adds fluoride and chlorine to the water. The treatment plant and fixtures are beyond useful life. The city will construct a new water treatment plant with new media filters and chemical feed equipment to treat the water for arsenic, iron and manganese removal The Minnesota Department of Health considers this a reasonable project for the drinking water needs of the city of Darwin.
III. Environmental impact
The environmental impact for the project will be shortterm construction-related disturbance limited to noise and dust. The shortterm impact will be mitigated by the use of standard construction practices. Erosion and sedimentation measures will be used as recommended by the Soil Conservation Service and The Department of Natural Resources. A storm water pollution prevention plan will be included in the contract documents for the construction contractor.
The proposed project is expected to result in no direct impacts to: threatened or endangered plants; flood plains; nearby farmland; historic, architectural, cultural, or archeological features; shore lands, or air quality nonattainment areas.
