NOTE: The National-Scale Air Toxics Assessment (NATA) provides only aggregate data on 1996 point source releases in an area. To help identify sepcific companies which may be responsible for these releases, Scorecard disaggregates summary point source data to facility-level data based on the 2002 Toxics Releases Inventory (TRI). NATA and TRI data for an area often differ, because they involve different reporting years (1996 vs. 2002) and aggregation methods (NATA often includes point source emissions from outside geopolitical boundaries, since these can impact estimated exposures in an area).
