NORWAY — Another problem has emerged with the $3 million turbine runner replacement project at Norway’s Sturgeon Falls Hydroelectric Facility, one that could potentially cost the city more than $100,000 to correct.

Steven Denicourt of Slovenia-based Litostroj Hydro Inc., told the Norway City Council they learned during the runner replacement that the unit 2 generator shaft is out of alignment.

The city earlier this year decided to repair unit 2 before unit 1 after finding water turbulence has caused the runners — the metal blades on the turbines — to twist and crack over the years.

But they discovered while reassembling the new runners that the existing shaft is off axis, making it bowed or “banana-ed” as it rotates, which could eventually lead to a breakdown, Denicourt said. He recommended moving the generator to straighten the configuration.

The $106,040 estimated cost is the “worst-case scenario” and the work is expected to be much less, Denicourt and Norway City Manager Ray Anderson said. Still, it potentially raises the total cost of the project to $3.3 million, about $220,000, or 7.1 percent, above the original project estimate, Anderson said.

The council voted 3-1 for the change order, with council member Jeremy Oja in opposition. Mayor Candy Brew was absent.

The 111-year-old Sturgeon Falls Hydroelectric Facility on the Menominee River generates power for residents and businesses in the city and parts of Norway Township.

In other business Monday, the council:

— Approved hiring Georgia-based company McLean Engineering for a $1,500 study to determine what the city should charge for telephone and cable use of Norway-owned electric poles. Michigan legislation allows wireless companies to attach equipment to existing municipal utility poles, but they must pay a rental fee for that access. This study will calculate a proper fee and update the city’s rental contracts for its 2,200 poles. The city now charges $8.50 per pole; the new fee is expected to be higher, perhaps double, Anderson said. McLean is expected to report back in about 30 days.

— Agreed to purchase a new pickup truck with V-plow for the Sewer Department from Era Chevrolet for $37,833.98. The Norway dealership submitted the only bid.

— Authorized a $98,786.31 payment to Gundlach Champion Inc. for the city’s ongoing wastewater treatment plant upgrade project, which is funded through U.S. Department of Agriculture-Rural Development grants and loans.

— Also approved applying the $159,455.70 left for the city’s water project toward two city bond issues, with the $72,000 2016 B issue being paid off completely with interest, Anderson said.

— Authorized signs from Nov. 16 to 18 at four sites in the city for the Jake Menghini Museum’s Taste of Chocolate event set for Nov. 17. This is a major fundraiser for the museum and coincides with a craft show for Holy Spirit School in Norway.
