RE: REQUEST FOR ENVIRONMENTAL COMMENT
The City of Motley is applying to the Minnesota Public Facilities Authority (PFA) for financial assistance to be used to construct a public water treatment plant, new well and new ground storage adjacent to the new well. Funds are being requested pursuant to the Drinking Water Revolving Fund as administered by the PFA and the Minnesota Department of Health. The City is preparing to undertake the following activities:
The proposed Water Treatment Plant will include the following:
1. Construct a water treatment plant, with a filter capacity to treat up to 560 gpm, to remove high levels of manganese, iron, and reduce extreme hardness from the raw water supply. Water will cascade downward through the aerator releasing gases in the water while oxygen is provided from the upward flowing of air. A detention time of 40 minutes will follow oxidation. The water will then flow through filters that will be constructed of concrete (for longer design life). The filtered water will then flow into a clearwell, and from here be pumped to the ground storage tank where it will be pumped into the distribution system. The clearwell will also be used as storage for backwashing filters. A chemical feed facility is where potassium permanganate and a corrosion inhibitor are added. Flouride is added from a separate dedicated room, and as required by current building codes, gas chlorine from another dedicated room. A backwash reclaimation system will also be constructed, to reduce water waste.
2. Construct a new ground storage tank adjacent to the new water treatment plant.
3. Construct a new well in the same vicinity of well #3, both of which will be used to provide the City with the majority of its water supply. The two wells will be used independently of each other and will not be used simultaneously to avoid excess drawdown of the acquifer.
Funding approval is anticipated. Release of these funds requires the preparation of an environmental review and compliance with the requirements of the National Environmental Policy Act of 1969 (NEPA), as amended, and certain other laws and regulations. The City is in the process of completing the environmental review and is soliciting comments as they relate to this project. Written comments to consider environmental impacts will be accepted through February 14th, 2014 at 5:00 p.m. Submit them to:
