Tank Space Allocation. The tankage available at a DESP is totaled by type of product held, (for example,
ten 10,000 bbl tanks total 100,000 bbl of space for JP8). This total space is then divided into four areas: vapor
space, POS, BPWRS, and unobtainable inventory.
a. Vapor space is the top 5 percent total space available. This allows for fuel expansion and vapors.
b. POS consists of operating level and safety level.
c. BPWRS.
d. Unobtainable/unusable inventory is the portion of the inventory needed to prime the
storage/distribution systems. It consists of pipeline fill, manifold inventory, and tank bottom below the suction
line. The inventory is not available to meet day-to-day operations.
2.
Petroleum Stocks at DESPs. They fall into two distinct categories: the POS and BPWRS.
a. Peacetime Operating Stock. POS is the amount of fuel required to sustain peacetime operations in
support of military demands to be maintained at a DESP. If additional storage space is available, DESC may
direct, on exception or emergency basis, additional POS be stored at a DESP for short periods of time.
(1) The POS is broken down into the operating level and the safety level.
(a) The operating level supports the day-to-day operations requirements.
(b) The SL is used to maintain operations when normal resupply is interrupted. The purpose of
the SL is to protect DESPs from stock outages where no BPWRS are held or to provide a confidence level that at
least 85 percent of a specific location's authorized BPWRS levels are available. BPWRS will generally serve as
the safety level. In unusual conditions, DESC may authorize augmented safety level stocks in addition to the SL,
(for example, at certain times of the year, the DESP could not be resupplied).
(2) POS is computed annually by DESC-O for all DESPs in coordination with DERs/SCPs/CINC-
JPOs.
3.
Bulk Petroleum War Reserve Stock.
a. BPWRS are stocks that are held as part of the BPWRR. The BPWRR is based upon the contingency
OPLAN for that area as developed by the Joint Chiefs of Staff. BPWRS is positioned as close to the area of use
as possible; however, it is subject to the storage/funds availability and BPWRS less than 150 barrels may not be
practical to stock. BPWRS is in addition to POS. BPWRS in CONUS must be directly supporting an OPLAN.
In OCONUS, BPWRS is to support military operations in a CINCs theater and cannot fall below the minimum
needs sets up in common for NATO.
