Interior Property Management Directives (IPMD) supplement the Federal Management Regulations (FMR), (41 CFR 102). The numbering system for the IPMD follows that of the FMR as outlined in FMR..

All IPMDs from Subpart 114-1 through Subpart 114-49 supplement corresponding parts of the FMR. IPMD from Subpart 114-50 through Subpart 114-60, while consistent with the FMR, are stand-alone directives defining the Department of the Interior methodology for the management of property. Not all of the FMRs have been supplemented in the IPMD. Only where it has been necessary to add or further delineate material in the FMR, have supplements been provided.  You may direct your questions about the IPMD to Albert Green.
