aBased on 1979 oil production volumes, water: oil ratios of 0.1 (U.K.) to 0.8 (U.S.A), and best estimate oil content of produced water.

bData reported as means for various periods: Gulf of Mexico Outer Continental Shelf 1996-1998 (Rainey, pers. comm., 2000); Texas Territorial Seas Fourth Quarter 1999 (McClary, pers. comm., 2000); Louisiana Territorial Seas 1992 (Hale, pers. comm., 2000); California OSC 1989-1998 (Panzer, pers. comm., 2000); Alaska Territorial Seas 1997-1999.

eData reported as means for 1996-1998 (UKOOA, 1999)

fData reported as means for 1996-1997. Includes water and oil discharges for produced water and ballast/drainage water (NOIA, 1998)
