RECEIVING WATER:
Unnamed Tributary to Bridger Creek
PERMIT NUMBER:
MT0031631
The City of Bozeman has applied for a renewal of the Montana Pollutant Discharge Elimination System (MPDES) Permit No. MT0031631 under the Montana Water Quality Act of Montana for their Lyman Creek Reservoir. The City of Bozeman utilizes Lyman Creek Spring as a potable water supply. Spring water is collected from the Lyman Creek drainage through a series of gravel beds and infiltration piping which directs water to a treatment and storage facility. Treatment buildings include an Inlet Control Building and an Outlet Control Building with a 5-million-gallon water storage reservoir. Water flows through the Inlet Control Building piping into the water storage reservoir. The reservoir holds treated water for distribution to city residents before it flows through the Outlet Control Building as demand warrants.
The 5-million-gallon water storage reservoir consists of a concrete basin overlaid with a polyethylene liner. There is a steady leak in the liner, which is the source of water covered under this discharge permit. Water is collected in an 8-inch drainpipe under the liner, which flows through a Parshall flume and then down the unnamed drainage to a small pond and then to Bridger Creek. Ground water from under the liner may also be collected in the 8-inch pipe. The facility and storage reservoir are located on public land, approximately 1.0 mile north, northeast of Bozeman, Montana. The proposed permit maintains current permit limits requiring the removal of chlorine and fluoride to levels that will not cause degradation of existing water quality. The permit requires periodic self-monitoring of discharge quality and quantity with monthly reporting of results.
