The Code Commission shall annually arrange for the codification and incorporation into the Code of Virginia of all general, special and limited compacts to which the Commonwealth is a party. Within the discretion of the Commission, such incorporation may be through insertion within the existing text and organization of the Code of Virginia or as a freestanding volume. The Commission shall, on or before July 1 of each year, transmit to the Secretary of the Commonwealth a copy of each new, amended or repealed compact as it was adopted by the Commonwealth in accordance with § 2.2-403.
