Section 3423 - Oriental Fruit Fly Interior Quarantine (Quarantine Regulation 28)

(1) An area shall be designated as under quarantine when survey results indicate an infestation is present, the Department has defined the infested area, and the local California County Agricultural Commissioner(s) is notified and requests the quarantine area be established. The Department shall also provide electronic and/or written notification of the area designation(s) to other California County Agricultural Commissioners and other interested or affected parties and post the area description to its website at: www.cdfa.ca.gov/plant/off/regulation.html. An interested party may also go to the above website and elect to receive automatic notifications of any changes in quarantine areas through the list serve option.

(2) An infestation is present when:

(3) The initial area under quarantine shall be a minimum of a 4.5 mile radius surrounding the qualifying detections being used as an epicenter. Commercial host properties shall not be split by the quarantine boundary line and the boundary line shall be expanded beyond the 4.5 miles as necessary to encompass such host material in its entirety. Wherever possible, known accepted mapping features, including but not limited to roads, streets, highways, creeks, streams, rivers, canals, city, county, State, park and forest boundary lines are used first and if there are no acceptable features such as these then imaginary lines with or without latitude and longitude points may be used.

(4) Any interested party or local 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.

(5) The infested area designation shall be removed if no additional life stages are detected by trapping or visual surveys for three life cycles after the last detection within the quarantine area.

(6) A life cycle is an estimate of insect phenology based on a heat degree day temperature driven model. Base developmental temperature thresholds are used in this model's calculations and it estimates the generation time period necessary for the completion of a generation of Oriental fruit fly. Daily minimum and maximum temperatures are used to produce a sine curve over a 24-hour period. The degree days for that day are estimated by calculating the area above the threshold and below the curve, assuming that the temperature curve is symmetrical around the maximum temperature. For Oriental fruit fly the Department uses the lifecycle model with 47.1° Fahrenheit base developmental temperature and 1125 degree days Fahrenheit per generation.

(1) All fruit of the plants listed in CCR 3591.2(b) Oriental Fruit Fly Eradication Area.

(2) Any other product, article, or means of conveyance when it is determined by the director or county agricultural commissioner to present a hazard of spreading live Oriental fruit fly and the person in possession thereof has been so notified.

(1) At wholesale level, articles and commodities covered which have been commercially produced within the area under quarantine are prohibited movement from or within the area under quarantine except in accordance with the following provisions:

(2) At the wholesale level, articles and commodities covered which have been commercially produced outside the area under quarantine are prohibited movement into the area under quarantine except when accompanied by a shipping document indicating the point of origin and destination and moved in accordance with the following provisions:

(3) At the retail level, articles and commodities covered which have been commercially produced are prohibited movement from or within the area under quarantine except when the person in possession has a sales slip or other comparable document showing the commodity was purchased from a commercial establishment.

(4) Articles and commodities covered which have been noncommercially produced within the area under quarantine, including "backyard" production, are prohibited movement from the premises where grown except under written authorization of the director or county agricultural commissioner.

(5) Articles and commodities covered which have been noncommercially produced outside the area under quarantine are prohibited movement into the area under quarantine except when the person in possession has signed a statement showing the commodity, amount, origin, destination, and date of transportation.

(6) Within the area under quarantine, no wholesale or retail establishment shall handle, sell or offer for sale any article or commodity covered unless such commodities at all times are maintained in a manner approved by the director to preclude exposure to Oriental fruit fly.
