Except as otherwise provided in paragraph (b) of this section, the Administrator will list as a quarantined area in paragraph (c) of this section each State, or each portion of a State, in which plum pox has been detected through inspection and laboratory testing, or in which the Administrator has reason to believe that plum pox is present, or that the Administrator considers necessary to quarantine because of its inseparability for quarantine enforcement purposes from localities in which plum pox has been detected. Less than an entire State will be designated as a quarantined area if the Administrator determines that:

The State has adopted and is enforcing restrictions on the intrastate movement of the regulated articles that are substantially the same as those imposed by this subpart on the interstate movement of regulated articles; and

The designation of less than the entire State as a quarantined area will prevent the interstate spread of plum pox.

The Administrator or an inspector may temporarily designate any nonquarantined area in a State as a quarantined area in accordance with paragraph (a) of this section. The Administrator will give a copy of this regulation along with a written notice for the temporary designation to the owner or person in possession of the nonquarantined area. Thereafter, the interstate movement of any regulated article from an area temporarily designated as a quarantined area will be subject to this subpart. As soon as practicable, this area will be added to the list in paragraph (c) of this section or the designation will be terminated by the Administrator or an inspector. The owner or person in possession of an area for which the quarantine designation is terminated will be given notice of the termination as soon as practicable.

The areas described below are designated as quarantined areas:
