FONSI:  Finding of No Significant Impact
ROD: Record of Decision
RPZ: Runway Protection Zone: Clearing trees,  ground structures (homes) & other obstacles to allow for larger, lower planes, carrying more fuel, disingenuously promoted under the guise of ‘public safety’.
EA: Environmental Assessment.  Limited Study of environmental effects. 
EIS: Environmental Impact Statement.  More thorough analysis of environmental effects.
SEGMENTATION: Breaking expansion into smaller projects to avoid scrutiny of collective environmental effect, i.e. allows airport & FAA to avoid performing EIS. 

PFAS/PFOA/PFOS: substances found in Firefighting Foam which can contaminate drinking water and impact health. 
PM2.5: Fine particulate matter, which is invisible but can enter the body and travel deep into tissues, specifically the lungs.
