Formed in 1995 by EPA, several other federal and state agencies, and several private organizations, the National Advisory Committee on Acute Exposure Guideline Levels for Hazardous Substances (referred to as the NAC) develops, reviews, and approves acute exposure guideline levels (AEGLs) for up to 400 extremely hazardous substances (EHSs). AEGLs have a broad array of potential applications for federal, state, and local governments and for the private sector. They are necessary for prevention and emergency-response planning for potential releases of EHSs, either from accidents or as a result of terrorist activities. This report includes an assessment of the NAC's draft AEGLs documents for the following 17 chemicals: acetaldehyde, arsenic trioxide, benzene, 1,3-butadiene, butane, chloroacetaldehyde, chlorobenzene, hexane, jet propellant fuels 5 and 8, ketene, methylene chloride, oleum, propane, propionaldehyde, sulfuric acid, sulfur trioxide, and trichloroethylene. The report also summarizes the committee's conclusions and recommendations for improving the Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Substances, published in 2001.
