Chapter 3 ⎯ Affected Environmentcifically listed. The USEPA interprets petroleum to include hazardous substances found naturally incrude oil and crude oil fractions, such as benzene, and hazardous substances normally added to crudeoil during refining. Petroleum additives or contaminants that increase in concentration in petroleumduring use are not excluded from CERCLA regulations.Most industrial operations for the Army installations in Hawaii use the “Super Station” centralizedmotor pool southwest of Lyman Road at Building 2805 on SBMR. All fuel for industrial use is transportedfrom the HAFB Fuel Farm via Tesoro and stored in aboveground storage tanks (ASTs) at theSuper Station (USAG-HI 2004). Two Army and Air Force Exchange Service (AAFES) retail fillingstations are located on SBMR at buildings 80 and 1167. Each distributes different grades of unleadedgasoline, with diesel fuel also sold at the first station.Both underground storage tanks (USTs) and ASTs are used to store petroleum products and fuels atlocations throughout the project area. POL storage is summarized in the following paragraphs by locationincluding USTs, ASTs, and oil-water separators.Underground Storage TanksThere are a number of in-use and permanently out-of-use USTs and leaking underground storagetanks (LUSTs) at SBMR and WAAF. For both DMR and KTA, only one UST remains in use at eacharea.Aboveground Storage TanksThere are 18 motor pools at SBMR. Some motor pools use ASTs to store diesel fuel or used oil inconjunction with vehicle maintenance. All fuel for industrial use is transported from the Hickam AFBFuel Farm via Tesoro and stored in four ASTs at the Super Station (USAG-HI 2004). Additionally,ASTs are used by many buildings on base to store liquid petroleum gas (LPG), also known as propane,to fuel hot water heaters.Several ASTs on WAAF in the area of the aircraft runway contain diesel or aviation gas. Emergencygenerators can be found throughout SBMR, SBER, and WAAF. Many of these units contain integratedtanks to store fuel as opposed to being connected to separate ASTs. A list of these units ismaintained by the DPW (USAG-HI 2004). There are no known ASTs on DMR. There is one AST onKTA used to store propane.Oil-Water Separators, Wash Racks, and Grease TrapsOil/water separators (OWSs) separate oil, fuel, and grease from water by gravity because these substanceshave a specific gravity that is lower than that of water (i.e., gasoline floats on water). OWSscan create environmental issues similar to those associated with USTs. Oils are skimmed from thesurface of these OWSs or USTs and recycled or disposed of; sediments are removed every 6 monthsor more frequently, if needed, by a service contractor. The DPW maintains a list of all OWSs, greasetraps, and wash racks on SBMR and these facilities are inspected regularly by the USAG-HI EnvironmentalCompliance Office (ECO), and DPW is responsible for maintaining these devices (USAG-HI 2004). There are no known OWSs on DMR, KTA, or PTA.3.1.8.3 Contaminated and Installation Restoration Program (IRP) SitesThe IRP is an ongoing DoD-administered program for identifying, evaluating, and remediating contaminatedsites on federal lands under DoD control. A comprehensive identification and evaluation ofall IRP sites on all existing Army training areas on Oahu and Hawaii was completed for the SBCTFebruary 2008 3–55 2/25th SBCT Final EIS
