B. Whenever the regulatory process has been suspended for any reason, any action by the agency that either amends the regulation or does not amend the regulation but specifies a new effective date shall be considered a readoption of the regulation for the purposes of appeal. If the regulation is suspended under § 2.2-4007.06, such readoption shall take place after the thirty-day public comment period required by that subsection. Suspension of the regulatory process by the agency may occur simultaneously with the filing of final regulations as provided in subsection B of § 2.2-4013. When a regulation has been suspended, the agency must set the effective date no earlier than fifteen days from publication of the readoption action and any changes made to the regulation. During that fifteen-day period, if the agency receives requests from at least twenty-five persons for the opportunity to comment on new substantial changes, it shall again suspend the regulation pursuant to § 2.2-4007.06.
