U.S. Environmental Protection Agency (EPA), “National Primary and Secondary Ambient Air Quality Standards,” 40 CFR 50, 2001;
The Derived Concentration Guides (DCGs) are based on the U.S. Department of Energy (DOE) standard (DOE 1993) and have been calculated using DOE models and parameters for internal (DOE 1988a) and external (DOE 1988b) exposure. These are shown in Table A-1. The most restrictive guide is listed when there is a difference between the soluble and insoluble chemical forms. The DCGs consider only the inhalation of air, the ingestion of water, and submersion in air. The principal standards and guides for release of radionuclides at the INEEL are those of DOE Order 5400.5, “Radiation Protection of the Public and the Environment.” The DOE standard is shown in Table A-2 along with the EPA statute for protection of the public, airborne pathway only.
Ambient air quality statutes are shown in Table A-3. Water quality statutes are dependent on the type of drinking water system sampled. Table A-4 is a partial list of maximum contaminant levels set by the EPA for public drinking water systems in 40 CFR 141 (2002).
