| Abstract |
Previously, the analysis of the potential for excess local mercury deposition surrounding U.S. EGUs was located in Appendix G of the National-Scale Mercury Risk Assessment. In response to public comments, we have moved this information to a separate TSD, re-titled the analysis, and provided additional technical details. EPA calculated the average EGU-attributable deposition (based on CMAQ modeling of mercury deposition) in the area 500 km around each plant and the average EGU attributable deposition in the area 50 km around each plant. The difference between those two values is the excess local deposition around the plant. This analysis shows that there is excess deposition of Hg in the local areas around EGUs, especially those with high Hg emissions. Although this is not necessarily indicative of higher risk of adverse effects from consumption of MeHg contaminated fish from watersheds around the U.S. EGUs, it does indicate an increased potential that Hg from U.S. EGUs will impact local watersheds. |
