The BLM Directives System is comprised of both temporary and permanent directives. Permanent directives are included in the BLM Manual System and consist of Manuals which provide program instructions. These instructions are in effect until the Manual is revised or removed from the BLM Manual System.
Directives remain in effect until they are superseded, canceled, or expire.
The Bureau's Paperwork Management System uniformly identifies all records or documents, regardless of physical form or characteristic, based on a logical numeric coding system. Related subsidiary subjects and corresponding codes fall under each of these 9 major subject areas. The subjects are codified by a series of numbers, generally with a four-digit number to the left of the decimal and subsidiary numbers and letters to the right of the decimal. The Bureau's listing of Subject Codes is available on-line. The BLM Manual System is a permanent record of written policy and procedural instruction for BLM employees.
