Amendment of HLB Interior Quarantine Regulation

Regulatory Statewide

To streamline the quarantine regulatory process while continuing to control the spread of Huanglongbing, the California Code of Regulations Section 3439, Huanglongbing Disease Interior Quarantine, was amended to allow the California Department of Food and Agriculture (CDFA) to administratively update the HLB state interior quarantine boundaries.

Since May 2017, 16 HLB quarantine expansions have occurred and been submitted to the Office of Administrative Law (OAL) for approval. The new administrative process will significantly cut down on regulatory staff workload as well as the lag time between county commissioner approval of proposed quarantine boundaries and OAL approval.

The process to implement a quarantine and update quarantine boundaries is described in the amended regulation: http://pi.cdfa.ca.gov/pqm/manual/pdf/423.pdf.

Quarantine boundary and program updates are sent out through the Lyris notification system. To receive updates on HLB quarantines, visit: https://www.cdfa.ca.gov/plant/hlb/signup-email-updates.html
