Evaluation of Human Health Risks Associated with Fog Oil Training at Fort Leonard Wood, Missouri Preliminary Risk Evaluation Report. (Revision).

Recommendations of the 1995 Defense Base Realignment and Closure Commission require the closing of Fort McClellan, Alabama and relocation of essential missions to other installations. Pursuant to the National Environmental Policy Act of 1969 NEPA the Army is required to prepare an Environmental Impact Statement EIS to address the environmental and socioeconomic impacts of relocating the U.S. Army Military Police School and U.S. Army Chemical School, and several associated support units to Fort Leonard Wood FLW, Missouri. One of the missions to be transferred to FLW is obscurant or smoke training with fog oil. As part of the EIS process, a comprehensive review of the available scientific literature was conducted to evaluate the human health effects associated with fog oil obscurant training. The human health literature evaluation report has been included as Appendix E to this report COE KC 1996a. The preponderance of evidence from the literature on the health effects of obscurant generated with SGF-2 Standard Grade Fuel fog oil manufactured after 1986 in accordance with military specification, MIL-F-12070C, Amendment 2 US Army, 1986 and specifications thereafter, indicate there is limited potential for adverse effects to humans COE KC 1996a. In 1986, military manufacturing specifications for SGF-2 were altered to required manufacturers to remove carcinogens and potential carcinogens from the oil.
