Plans for a new hydroelectric power plant on the north bank of the Kansas River are reaching a new stage.

Two key permits for a proposal by Lawrence-based Bowersock Mills and Power Co. soon will be discussed.

City commissioners on Tuesday will consider approval of a special-use permit that would allow for a four-turbine, multi-story plant to be built just east of the Bowersock Dam.

Commissioners also are being asked to begin the process of allowing Bowersock to apply for up to $18 million in industrial revenue bonds. The bonds would be issued by the city, but backed by a financial responsibility of Bowersock.

Tuesday’s action would allow the company to begin working on securing the bonds. The city commission would be required to take another vote to issue the bonds.

The U.S. Army Corps of Engineers also has opened a public comment period on a water quality certification permit for the project. The corps is accepting comments until July 15.

Comments can be sent to U.S. Army Corps of Engineers, Kansas City Regulatory Office, 601 E. 12th St., Kansas City, MO 64106.

City commissioners meet at 6:35 p.m. Tuesday at City Hall.
