Effective Date of Rule: Thirty-one days after filing.

     Purpose: There are many equine diseases that have become a threat to the equine industry in Washington state, therefore, the department proposed to add new sections within the current chapter 16-71 WAC, Equine infectious anemia. The proposed new sections define each of the diseases and the requirements if equine were to test positive. Because the department proposed to add new equine diseases to the WAC, the department proposed changing the name of this WAC to equine diseases in Washington state.
