Chapter 3 ⎯ Affected EnvironmentThe following subsections summarize the hazardous materials and wastes used or generated by theArmy installations.Hazardous materials and wastes at the Army installations in Hawaii include ammunition, live-fire,and UXO; POLs; contaminated and IRP sites; lead; asbestos; PCBs; pesticides/herbicides; radon; andhazardous wastes, including waste oils, depleted uranium, and biomedical waste. The Transfer AccumulationPoint at SBER, Building 6040, stores hazardous materials and wastes used and generatedat SBMR, SBER, and WAAF. The Army maintains updated material safety data sheets for all hazardousmaterials used. The hazardous materials and wastes used and generated within the ROI in Hawaiiare summarized in the following subsections.3.1.8.1 Ammunition, Live-Fire, and UXOLive-fire training exercises occur within the range areas and various types of ordnance are used. Thegeneral public is not allowed into areas where ammunition is stored or used. Any unused ammunitionmust be returned to the original storage facility at the end of the exercise.Live-Fire TrainingLive-fire training takes place at SBMR and PTA. Live-fire activities include artillery and mortar(A&M) training, which requires the use of bags filled with explosive propellant for artillery and similarexplosive propellant charges for mortars. Charges that are not used during training are burned,creating a residue. Residues from burned propellant are the only hazardous wastes temporarily storedat the range burn site in a designated hazardous waste satellite storage point.SDZs are associated with live ammunition firing at range training facilities (SBMR and PTA).SBMR’s SDZs exist roughly within an arc formed by Area X (the eastern boundary), Trimble Road(the southern boundary), and the Waianae Mountain Range (the western boundary). The direction offire is generally west to north. The area supports small arms, mortar, and artillery training. No livetube-launched, optically tracked, wire-guided missile, air-to-ground, or ground-to-air firing is conductedat the SBMR ranges (Belt Collins 1993). In recent years, there have been no problems involvingthe public and the storage, transportation, and use of ammunition for training at SBMR (USAG-HI 2004).SDZs are also designated for the ranges at PTA (Sato 1996). Their construction is based on informationin AR 385–63 and the draft update of this regulation. Increased emphasis is placed on the effectsof ricochets at closer ranges in the draft version. SDZs are configured toward a cumulative ordnanceimpact area (approximately 51,000 acres) in the central portion of PTA. In addition, although improvedconventional munitions (ICMs) are no longer used on any Army training land due to the extremesafety risk (HQDA 2001), there is a 16,800-acre ICM impact area within the larger impact area.ICMs, also referred to as cluster bombs, are artillery munitions that contain multiple submunitions.The ordnance impact area and ICM area are not accessible to the public.Permanent ammunition storage is not authorized on SBMR or PTA. During training, ordnance istemporarily stored in ammunition holding areas. At completion of training, unused ammunition is returnedto the ammunition storage point (ASP) located on WAAF in buildings 1538 and 1551. Weaponsare stored in the unit areas between training sessions. The Naval Magazines at Lualualei provideammunition to WAAF (Belt Collins 1993). These buildings act as permanent ordnance storage for allof USAG-HI (USAG-HI 2004).February 2008 3–53 2/25th SBCT Final EIS
