BAY CITY, Mich. (AP) _ A big public turnout is possible as leaders in Bay County consider a measure to prohibit discrimination based on sexual orientation or gender identity.

The hearing is Tuesday at 4 p.m. Ernie Krygier, chairman of the Bay County Board of Commissioners, tells The Bay City Times (http://bit.ly/LPtZau ) that the proposal ``grew into a major discussion.''

Tuesday's hearing is the final public meeting on the issue before a vote on the proposed ordinance that's expected in March.

If the ordinance is approved, it could become law as soon as May 1.

The ordinance has been in the works for months and is modeled after similar measures adopted in other Michigan communities. The ordinance would affect entities owned and operated Bay County, as well as contracts the government makes.
