preliminary data submitted to EPA from
sources as of February 16,2011. EPA will
update maps as it corrects data over time.
Note: This map displays changes occurring between 2008 and 2010; many facilities already have advanced controls and low emission rates and
therefore show no change. If a unit has not yet reported all four quarters of 2010 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.
