2.1 Purpose. This chapter authorizes and prescribes the criteria for issuance of procedural directives by the Office of the Secretary. The Department of the Interior (DOI) directives provide guidance in the subject area of aircraft management and operation. General policy statements and responsibilities regarding the Departmental aircraft management program are published in Departmental Manual (DM) Parts 350-354.
2.2 Issuing Authority. All 350-354 DM releases are signed by the Assistant Secretary - Policy, Management and Budget. All material published in the Handbooks, Operational Procedure Memoranda (OPMs), Information Bulletins (IBs), Operation Guides (OGs), and OAS Instructions is issued under the authority of the OAS Director.
2.3 Handbooks. Handbooks provide detailed procedures and requirements of policy established in the applicable chapter of the DM.
2.4 Operational Procedure Memoranda (OPMs). Temporary or interim directives are issued Department-wide as OPMs to permit the timely dissemination of instructional and procedural material. They are published under the issuing authority of the OAS Director, or a Regional/Area Director for matters within their delegated responsibility.
2.5 Information Bulletins (IBs). Announcements and information of general interest are published as IBs. IBs are non-directive, bear no expiration date, and may be discarded at the discretion of the recipient. Any superseded IB will be noted in the new release. Annually, the Office of Aircraft Services will issue a listing of all current IBs.
2.6 Operation Guides (OGs). Guides communicate preferred procedures for a specific aspect of aviation operations, but are not mandatory in nature at the Department level but may be adopted by the Bureau.
