and no significant impacts are expected from its withdrawal. If a repository was to be<br />

built in an arid region, water might need to be transported to the site from areas <strong>of</strong><br />

abundant supply.<br />

5.4.2 Nonradiological Effluents<br />

Nonradiological effluents from repository construction include dust and pollutants<br />

generated from machinery operation during surface facility construction and mining opera-<br />

tions. Burning the quantities <strong>of</strong> fossil fuels listed in Tables 5.4.2 and 5.4.3 results in<br />

air pollutant emissions, but concentrations in air at the fenceline are not expected to<br />

result in any air quality degradation outside applicable limits (40 CFR 50). Estimates <strong>of</strong><br />

pollutant totals released to the atmosphere from operating equipment during construction<br />

are given in Table 5.4.4. These quantities are developed from the total quantities <strong>of</strong> fuel<br />

burned and emission factors for a given effluent (URS 1977).<br />

Fmissions from oil burning space heaters in a town <strong>of</strong> 30,000 population (about<br />

8,000 heaters) were estimated for a 20-yr period (the approximate time surface facilities<br />

at a repository are operating) in an effort to provide some perspective for effluents<br />

released during construction <strong>of</strong> a repository. The calculated emissions were:<br />

CO, MT 220<br />

Hydrocarbons, MT 120<br />

NOx, MT 540<br />

Particulates, MT 6,000<br />
