(k).   “Vectors or Vectors of Pierce’s disease” shall mean Homalodisca vitripennis , glassy-winged sharpshooter.

Section 3653.      Area Designation Procedures.

(a)     An area shall be designated as non-infested based on written affirmation to the Department by the local public entity that the area has been surveyed in a manner approved by the Department to detect vectors with negative results.

(b)     An area shall be designated as infested when the survey results indicate an infestation is present, the Department has defined the infested area, and the local public entity is notified immediately.  The Department will also provide electronic and/or written notification of the area designations to the other local public entities and other interested or affected parties. 

(c)   The local public entity may appeal an area designation by submission to the Department of a written request for review of the designation accompanied by clear and convincing evidence justifying a change in the designation.  The appeal must be filed no later than ten (10) working days following receipt of the notice of designation.  The Department must respond with a written decision no later than ten (10) working days following receipt of the appeal.  During the pending of the appeal, the designation under appeal shall remain in effect.

(d) The infested area designation shall be removed if:

(1) No additional vectors are detected by trapping or visual surveys during the period of January 1 through October 31 of the year following the last vector detection; or,

(2) Only adult vectors were detected and thorough vector survey/detection activities document that a breeding population is not present.

Section 3654. Inspection of Shipments and Disposition of Infested Shipments.

(a)   All shipments of bulk grapes and plants are subject to inspection by the agricultural commissioner upon arrival at destination.

(b)   Any shipment found to be infested with live vectors shall be refused delivery and may be immediately destroyed unless no damage would be caused to agriculture if the shipment is returned to origin or processed or treated in a manner approved by the Department to eliminate the vectors.
