Footnotes:

(a) TAP/day = tons aluminum produced per day.
(b) Includes particulate and gaseous fluorides.
( c) Washington regulates based on sulfur content in coke - limits to 60 lbs 20/TAP;
     Oregon limits emissions on an individual basis for each plant;
     Montana does not have an S0₂ atmospheric emission limit for aluminum smelters.
