Source apportionment of PM_2.5 at IMPROVE monitoring sites within and outside of marine vessel fuel sulfur emissions control areas.

ABSTRACT: Fuel sulfur emissions control areas have been established in a few marine coastal regions to reduce environmental impacts from combustion of high sulfur residual fuel oil (RFO). For example, in August of 2012, the U.S. began enforcing fuel sulfur limits on certain large commercial marine vessels up to 200 nautical miles (nm) of its coasts as part of a North American Emissions Control Area (NA-ECA), and in January of 2014, the U.S. began enforcing fuel sulfur limits on these vessels within up to 50 nm of Puerto Rico and the U.S. Virgin Islands as part of the U.S. Caribbean Sea ECA (USCAR-ECA). This work evaluates ECA effectiveness at reducing PM_2.5 from combustion of RFO by using both spatial analysis, comparing PM_2.5 source apportionment at IMPROVE monitoring sites la
