k CDA 2012 vs 2013 Comparisons, Annual S02 Emission Rate Changes at Facilities (Coal Units Only) United States Environmental Protection Agency With 10,000 Tons Change Between Years Source: 2012 data are final, 2013 are preliminary data submitted to EPA from sources as of February 24,2014. EPA will update maps as it corrects data over time. Note: This map displays changes occurring between 2012 and 2013; many facilities already have advanced controls and low emission rates and therefore show no change. If a unit has not yet reported 2013 emissions data to EPA, it is not included in this map. In areas with a dense: concentration of facilities, the facilities on the map may overlap and some may be impossible to see.
