BATH, Maine — Members of the largest union at Bath Iron Works voted Wednesday to return a former chapter president to that office.

Mike Keenan, a shipfitter who served as president of Local S6 of the machinists union from 2001 to 2008, will return as president in January after besting Terry Frost, according to current president Rich Nolon.

Of roughly 3,400 active members of the local union, 1,482 cast votes Wednesday, Nolon said.

In March 2008, Keenan and three other officers of the local chapter were escorted from the union hall amid claims of financial mismanagement and pornography being viewed on union-owned computers.

Keenan denied all allegations, but the chapter was placed into receivership and he and other officials were suspended.

The IAM eventually returned control of the chapter to Local S6. Keenan was barred from running for office for four years and former chief steward Michael Cyr for two.

Todd McPhee initially took over as president before Dan Dowling was elected to the office and served until 2013, Nolon said.

Three years ago, Keenan ran for the seat against Jay Wadleigh. Wadleigh served until February, when he took a position with the union’s District Lodge 4 in Lisbon.

Rocky Grenier was elected vice president and Jason Perry secretary-treasurer. Shawn Tardif will serve as conductor sentinel and Jeff Segars, Tom Darling and Ray Bilodeau as trustees.

In Wednesday’s other union voting, Ray Gauthier was elected chief steward at the Bath yard. Bill Barrows, Marc Bubar, Tim Sutter, Andy James and Tom Darling will make up the Bath grievance committee.

Rob Jacobs and current chapter president Rich Nolon were tied as chief steward at the Hardings Plant, with a run-off to be scheduled shortly, Nolon said.

Pat Toth, Dan Murphy, Clayton Reid and Ray Bilodeau will serve as the Hardings grievance committee.

New officers will be sworn in at the Local S6 monthly meeting on the third Saturday of January, Nolon said.
