,Law 100-605, Banjord Reach Comprehensive River Protection Study and Interim Protection,<br />

requires new activities near the Columbia River to minimize direct and adverse effects on the<br />

values for which the Columbia River is under study.<br />

No direct wastewater discharges to the Columbia River are planned under any of the alternatives.<br />

All remediation work will occur several miles from the river, sd there is no potential for<br />

stormwater runoff to the river.<br />

J.6 AIR EMISSION STANDARDS<br />

The Clean Air Act oj1977 establishes standards for the control of air emissions. Authority has<br />

partially been delegated to Washington State. Under 40 CFR 61 (Subpart H) and WAC 246-247,<br />

radionuclide airborne emissions from all combined operations at the <strong>Hanford</strong> <strong>Site</strong> may not<br />

exceed 10 mrem/yr effective dose equivalent to the hypothetical offsite maximally exposed<br />

individual. These regulations require verification of compliance through monitoring.<br />

"t3eneral Regulations for Air Pollution Sources" (WAC 173-400) and "Controls for New<br />

Sources of Toxic Air Pollutants" (WAC 173-460) establish air emission requirements for new or<br />

modified sources of air pollutants. These regulations establish new source review requirements,<br />

general emissions standards (e.g., control of fugitive dust), and technology requirements.<br />

The radionuclide emission limits would apply to all fugitive, diffuse, and point-source air<br />

emissions of radionuclides generated by any of the removal or ex situ alternatives. If there is the<br />

potential for any non-zero radioactive emissions, best available radionuclide control technology<br />

(BARCT) wille,AA be required. If the alternative willettd generate an increase of toxic air<br />

pollutants to the atmosphere above the small quantity emission rates, implementation of BARCT<br />

willeNkt be required.-_01.4-and th - U.'ash'<br />

The following information provides an analysis of how each alternative is anticipated to comply<br />

with the ARARs and •i'BCs for air standards.<br />
