A. The Board may summarily suspend or restrict a permit issued pursuant to § 4.1-1602 without a hearing if the Board finds that such suspension or restriction is necessary to prevent substantial danger to public health or safety. The Board shall make decisions to summarily suspend or restrict a permit only during an in-person meeting in which a quorum is present; however, if, after a good faith effort, the Board is unable to assemble a quorum and a majority of the Board members determine that continued operation by the permittee constitutes a substantial danger to public health or safety, the Board may summarily suspend the permit during a telephone, video, or other electronic conference. Institution of proceedings for a hearing shall be provided simultaneously with a summary suspension. The Board may summarily restrict a permit without proceeding simultaneously with notification of an informal conference pursuant to § 2.2-4019 or Board regulations. Such hearing or conference shall be held within a reasonable amount of time after the summary suspension or restriction is issued.
