301.86-3—Quarantined areas.
(a) Designation of quarantined areas.
In accordance with the criteria listed in paragraph (c) of this section, the Administrator will designate as a quarantined area each field that has been found to be infested with pale cyst nematode, each field that has been found to be associated with an infested field, and any area that the Administrator considers necessary to quarantine because of its inseparability for quarantine enforcement purposes from infested or associated fields. The Administrator will publish the description of the quarantined area on the Plant Protection and Quarantine Web site, http://www.aphis.usda.gov/plant_health/plant_pest_info/potato/pcn.shtml. The description of the quarantined area will include the date the description was last updated and a description of the changes that have been made to the quarantined area. The description of the quarantined area may also be obtained by request from any local office of PPQ; local offices are listed in telephone directories. After a change is made to the quarantined area, we will publish a notice in the Federal Register informing the public that the change has occurred and describing the change to the quarantined area.
(b) Designation of an area less than an entire State as a quarantined area.
Less than an entire State will be designated as a quarantined area only if the Administrator determines that:
(1)
The State has adopted and is enforcing restrictions on the intrastate movement of the regulated articles that are equivalent to those imposed by this subpart on the interstate movement of regulated articles; and
(2)
The designation of less than the entire State as a quarantined area will prevent the interstate spread of the pale cyst nematode.
(c) Criteria for designation of fields as infested fields and associated fields.
(1) Infested fields.
The Administrator will designate a field as an infested field when a pale cyst nematode is found in the field.
(2) Associated fields.
The Administrator will designate a field as an associated field when pale cyst nematode host crops, as listed in § 301.86-2(b), have been grown in the field in the last 10 years and
(ii)
The field came into contact with a regulated article listed in § 301.86-2 from an infested field within the last 10 years; or
(iii)
Within the last 10 years, the field shared ownership, tenancy, seed, drainage or runoff, farm machinery, or other elements of shared cultural practices with an infested field that could allow spread of the pale cyst nematode, as determined by the Administrator.
(d) Removal of fields from quarantine—
(1) Infested fields.
An infested field will be removed from quarantine when a protocol approved by the Administrator as sufficient to support removal of infested fields from quarantine has been completed and the field has been found to be free of pale cyst nematode.
(2) Associated fields.
An associated field will be removed from quarantine when the field has been found to be free of pale cyst nematode according to a protocol approved by the Administrator as sufficient to support removal of associated fields from quarantine.
(3) Removal of other areas from quarantine.
If the Administrator has quarantined any area other than infested or associated fields because of its inseparability for quarantine enforcement purposes from infested or associated fields, as provided in paragraph (a) of this section, that area will be removed from quarantine when the relevant infested or associated fields are removed from quarantine.
