A hearing to determine whether a permit should be revoked, suspended limited, or conditioned shall be initiated by filing an accusation. The accusation shall be a written statement of charges which shall set forth in ordinary and concise language the acts or omissions with which the respondent is charged, to the end that the respondent will be able to prepare his defense. It shall specify the statutes and rules which the respondent is alleged to have violated but shall not consist merely of charges phrased in the language of such statutes and rules. The accusation shall be verified unless made by a public officer acting in his official capacity or by a duly appointed representative of the Board. The verification may be on information and belief.
