  32. Key Messages • Plume-in-Grid Messages • Plume-in-grid has a strong influence on near-field EGU contributions • Decreases localized regions of elevated concentration relative to their surroundings for all pollutants: ozone, PM and N & S deposition • In the far field • Increases or decreases small contributions depending on chemistry and meteorology • Contribution Messages • Non-EGU anthropogenic emissions are key contributors to interstate contributions, particularly to adjacent/bordering states • Transport of O3 and PM has large contributions by non-EGU emissions • N Deposition results show important role of non-EGU emissions
