Chapter 3 ⎯ Affected Environmentfire retardants and other solid materials. The Army is committed to removing or retrofilling all electricalequipment containing regulated amounts of dielectric fluid containing PCBs.A survey was conducted in 1991 to determine the concentration of PCBs in the electrical distributionequipment on military installations in Hawaii. The survey results indicated that there were PCBcontainingtransformers and electrical equipment throughout SBMR and in a few transformers atDMR and KTA. PCB concentrations in soil samples from PTA were below the listed PRG. Devicesthat were found to contain regulated levels of PCB have been either removed and upgraded with non-PCB devices, or were retrofilled or removed, drained, packaged, and disposed of in accordance with40 CFR Part 761 (PRC Environmental Management, Inc. 1995). No PCB-containing transformersremain.3.1.8.7 Pesticides/HerbicidesVarious types of pesticides, including insecticides, herbicides, fungicides, avicides (bird poison), androdenticides, have been used at USAG-HI installations to maintain the grounds and structures andprevent pest-related health problems. Pesticides and herbicides are primarily stored in four locationson SBMR and one location on KTA (USAG-HI 2004). Pesticides and herbicides are stored at PTA inapproved containers at the ENV Office facilities.3.1.8.8 RadonRadon is a naturally occurring, slightly radioactive gas that is produced by the decay of rock containinguranium. Inhalation of radon gas may be associated with an increased risk of lung cancer, and theUSEPA has made recommendations for safe radon levels in both residential housing and schools. Radonoccurs in low concentrations in the Hawaiian Islands. As part of the National Radon Database,the USEPA and the USGS have evaluated the radon potential in both Honolulu and Hawaii Counties.Data from several radon surveys in Hawaii show that concentrations are much lower than theUSEPA’s recommended action level of 4 picocuries per liter (pCi/L). Therefore, radon is not addressedin the individual installation analyses.3.1.8.9 Hazardous WastesThe primary function of the motor pool facilities on SBMR is vehicle maintenance. Although motorfuels were previously stored and distributed at these motor pools for military vehicles, all fueling forindustrial purposes now takes place at the Super Station. Most of the motor pool facilities have designatedwaste storage/holding areas with both primary and secondary containment for wastes generatedby shop and vehicle servicing. Normally, the waste products are temporarily collected and stored incontainers at a far corner of each motor pool, which is surrounded with sandbags for secondary containmentof potential leaks, and cordoned with barbed wire (Belt Collins 1993). The waste is separatedinto hazardous waste such as lithium batteries or Resource Conservation and Recovery Act(RCRA) chemicals, and non-regulated waste such as recyclable oil. The hazardous waste is broughtto the hazardous waste shope storage point (HWSSP), while the recyclable materials are brought tothe Recyclable Material Shop Storage Point (RMSSP) (USAG-HI 2004). Hazardous wastes collectedat HWSSPs are then transeferred to EPA-approved 90-day storage points on the installation beforebeing properly disposed of.Biomedical WasteThe Army follows strict guidelines according to AR 200–1 in the handling, use, and disposal ofmedical, dental, and veterinary supplies. Most medical waste within the project vicinity is producedand temporarily stored outside of the project area at Tripler Army Medical Center. The medical clin-February 2008 3–57 2/25th SBCT Final EIS
