BSB/PUBLIC WORKS - Ad from 2022-05-13

PUBLIC NOTICE The U.S. Department of Commerce, Economic Development Administration (EDA) is considering a request for Federal assistance from the City-County of Butte-Silver Bow to construct a Silver Lake Water System (SLWS) Improvements Project in Butte, Silver Bow County, Montana and Anaconda, Deer Lodge County, Montana. Pursuant to the National Environmental Policy Act of 1969, as amended, EDA is conducting an environmental assessment (EA) of the proposed project. The Silver Lake Water System Improvements Project addresses several deficiencies in the water storage, pumping, and distribution system. Butte-Silver Bow (BSB) selected the following improvements to address the identified deficiencies: (1) Replace the Ramsay Pump Station by expanding the adjacent TIFID Pump Station facility (Location: 46.008061°N, -112.676476°W); (2) Upgrade the Silver Lake East Dam outlets by separating the existing pump and gravity outlets, allowing BSB to discharge through the dam at two separate locations (Location: 46.166832°N, -113.216290°W); (3) Upgrade the Silver Lake Pump Station by replacing the 250 horsepower pump motors, installing variable frequency drives, and repairing or replacing the damaged intake pipe (Location: 46.166030°N, -113.221198°W); and (4) Update the SLWS instrumentation and flow measurement by adding new lake level and flow measurement locations throughout the system along with automation of data at both new and existing instruments. This data will be integrated into Butte-Silver Bow’s supervisory control and data acquisition (SCADA) system where it can then be viewed real time and historized for trending and record keeping purposes.
