Va. Code § 63.2-520
Public assistance shall be paid to or on behalf of the applicant monthly, or at such other time or times as the regulations of the Board may provide, by the treasurer, the district fiscal officer, or other disbursing officer of the county or city, upon order of the local board or local director, from funds appropriated or made available for such purpose by the local governing body of such county or city. Wherever two or more counties or cities have been combined to form a district pursuant to § 63.2-306, such public assistance payments shall be made by the district fiscal officer.
In the event, however, that the Board adopts regulations to provide for state issuance of public assistance payments, such public assistance shall be paid by the State Treasurer. In emergency situations or in the event of delay or error in a state issuance of public assistance payments, emergency payments may be issued by local boards as authorized by Board regulations.
