Air Emissions Section

Chapter 246-247 WAC contains regulations important to all facilities with the potential to emit airborne radioactivity. This includes federal facilities and state licensed facilities.

Federal Law

Clean Air Act Federal act authorizing EPA to regulate hazardous air pollutants including radionuclides.

EPA Regulations

40CFR61, Subpart A National emission standards for hazardous air pollutants, general provisions.
40CFR61, Subpart B radon-222 emissions to the ambient air from underground uranium mines.
40CFR61, Subpart H radionuclide emissions, other than radon, from U.S. Department of Energy facilities.
40CFR61, Subpart I radionuclide emissions emitted by federal facilities that are not regulated elsewhere.
40CFR61, Subpart K emissions of polonium-210 and lead-210 to the air from phosphorus plants.
40CFR61, Subpart Q emission of radon-222 to the ambient air from Department of Energy (DOE) storage or disposal facilities for radium-containing materials.
40CFR61, Subpart R emission of radon from phosphogypsum stacks.
40CFR61, Subpart T radon-222 emissions from uranium mill tailings piles that are no longer operational.
40CFR61, Subpart W emission of radon-222 from uranium mills and their associated tailings.
Laws & Regulations legal authorities for the regulation of air emissions of radionuclide.

NRC regulations

Part 20 - Standards for Protection Against Radiation
Subpart B - Radiation Protection Programs - 10 mrem constraint for radioactive air emissions.
Clean Air Act Federal act to regulate hazardous air pollutants which includes radionuclides.

Ecology Regulations

Chapter 173-401 WAC Establishes the elements of a comprehensive Washington state air operating permit program consistent with the requirements of Title V of the Federal Clean Air Act.
Chapter173-480 WAC Ambient air quality standards and emission limits for radionuclides. Defines maximum allowable levels for radionuclides in the ambient air and control emissions from specific sources.

Models

CAP88-PC Atmospheric transport model for assessing dose and risk from radioactive air emissions. Applicable to Department of Energy compliance with Clean Air Act.
COMPLY Atmospheric screening model for assessing dose from radioactive air emissions. Applicable to Department of Energy compliance with Clean Air Act, and Nuclear Regulatory Commission 10 CFR 20.
GENII-NESHAPs A model for use with routine chronic atmospheric releases of radionuclides, providing a standardized output in terms of radiation doses and risks.
