OLYMPIA -- An initiative to turn wholesale and retail liquor sales over to the private sector qualified for the ballot, state elections officials said Wednesday.

Initiative 1183, sometimes called the Costco initiative because the discount retailer is among its most ardent supporters, passed a random check of its petitions, David Ammons, a spokesman for Secretary of State Sam Reed said.

It joins I-1125, which would limit tolls and fees on roads, bridges and ferries. Elections officials begin a spot check of petitions Thursday on a third initiative, I-1163 which would require training and background checks for home health care workers.

All three initiatives submitted enough signatures that they were likely to qualify for the ballot.
