Even though informal adjudications do not require trial-type procedures, the responsible OA or component of OST should ordinarily afford the applicant or the regulated entity that is the subject of the adjudication (as the case may be), as well as other directly affected parties (if any), adequate notice and an opportunity to be heard on the matter under review, either through an oral presentation or through a written submission. Except in cases of a safety emergency or when the clear text of the relevant enabling act or government-wide regulation, such as 2 CFR part 180, expressly authorizes exigent enforcement action without a prior hearing, the responsible OA or component of OST shall give the regulated entity appropriate advance notice of the proposed enforcement action and shall advise the entity of the opportunity for an informal hearing in a manner and sufficiently in advance that the entity's representatives have a fair opportunity to prepare for and to participate in the hearing, whether in person or by writing. The notice should be in plain language and, when appropriate, contain basic information about the applicable adjudicatory process. In all informal adjudications, the responsible OA or component of OST shall adhere faithfully and consistently to the procedures established in any applicable procedural regulations.
