The Board may suspend the license or the approval of any (i) accredited training program, (ii) training manager or (iii) principal instructor of any person holding a license issued by it without a hearing simultaneously with the institution of proceedings for a hearing or an informal fact finding conference, if the relevant board finds that there is a substantial danger to the public health or safety that warrants this action. The Board may meet by telephone conference call when summarily suspending a license or the approval of an accredited training program, training manager or principal instructor if a good faith effort to assemble a quorum of the Board has failed and, in the judgment of a majority of the members of the Board, the continued practice by the licensee or approved individual or training program constitutes a substantial danger to the public health or safety. Institution of proceedings for a hearing or an informal fact finding conference shall be provided simultaneously with the summary suspension. Such hearing or conference shall be scheduled within a reasonable time of the date of the summary suspension. Allegations of violations of this section shall be made in accordance with § 54.1-307.1.
