The Senate vote Wednesday is expected to come in late afternoon or early evening.
It is expected to pass in the Senate with at least 25 votes, the number needed for approval. Five senators, two Democrats and three Republicans, have not indicated how they will vote.
If passed by the Senate, the measure moves to the House, which has enough votes to pass the bill by a more comfortable margin. Also, Democratic Gov. Chris Gregoire supports the measure and said she will sign it into law.
