Pre-Expended Bin Unit The PEB unit contains high-usage, mainte- nance-related consumable materials that have been expended from the supply department stock records and financial accounts. The purpose of the PEB is to shorten the issue and accounting procedures for recurring issues of maintenance-related materials. The PEBs are located where they are readily accessible to maintenance personnel and, when feaible, where they can be observed by the retail outlet Store- keeper to aid in recognizing abuses to the pre-expended system. Items subject to pilferage are retained within an enclosure with access limited to authorized personnel. The SRS is responsible for the management and maintenance of the PEBs by replenishment or turn-inaction, as required. PEB stock is limited to maintenance-related material having a minimum demand frequency of three per month. The quantity of each item pre-expended may not exceed an estimated 30-day supply, subject to the requirement that stock be replenished in full package quantities. The supply officer and the maintenance officer of the activity being supported are jointly responsible for determining those eligible items to be added or purged from pre-expended stocks. Eligible items with a unit cost of 0 or less may be routinely established in PEB stock. Eligible items with a unit cost in excess of 0 maybe pre- expended with the approval of the commanding officer. Stock records are reviewed quarterly to guarantee that all items have sufficient usage to be retained in pre-expended status and to correct any mixing of pre-expended items, As a minimum, any item that had no demand within the last 12 months should be purged from pre-expended stock and returned to the supporting supply department. Refer to OPNAVINST 4790.2, volume III, chapter 14, for items not authorized for inclusion in the PEBs. Program Management Unit The PMU is responsible for processing and expediting high-priority requirements, such as NMCS/PMCS, broad arrow, work stoppage, and EXREP. The PMU distributes daily status listings and performs a continuous reconciliation of outstanding requirements between supply and maintenance activities.
