3. Regional Haze Rule: Glide Path Toward ‘Natural Condition’ Natural haze is due to natural windblown dust, biomass smoke and other natural processes Man-made haze is due industrial activities AND man-perturbed smoke and dust emissions (A fraction of the man-perturbed smoke and dust is assigned to natural by policy decisions)
4. Origin of Fine Dust Events over the US Gobi dust in spring Sahara in summer US-scale fine dust events are mainly from intercontinental transport Fine Dust Events, 1992-2003 ug/m3

9. Sahara and Local Dust Apportionment: Annual and July • The maximum annual Sahara dust contribution is about 1 g.m 3 • In Florida, the local and Sahara dust contributions are about equal but at Big Bend, the Sahara contribution is < 25%. The Sahara and Local dust was apportioned based on their respect ive Al/Si ratios. • In July the Sahara dust contributions are 4 - 8 g.m 3 • Throughout the Southeast, the Sahara dust exceeds the local source contributions by w wide margin (factor of 2 - 4) Annual July
