Fuel Sample - WASHINGTON, DC - Petroleum Administration for Defense District (PADD) 1

The f ollowing pages contain inf ormation on the chemical composition and property characteristics of a commercial

gasoline f uel sample collected in a specif ied geographic area denoted by city , state and "PADD" number. PADD is

an acrony m meaning "Petroleum Administration f or Def ense Districts" and is commonly used by agencies such

as the US Energy Inf ormation Administration f or classif y ing petroleum product supply and consumption patterns.
