given tradable, mercury emission allowances in
proportion to the amount of coal they burn,
adjusted for coal rank x 1 Bituminous,
x 1.25 Subbituminous x 3 Lignite

15Result of the CAMR Rank Adjustment (1) target
Hg emission rates depend on where the coal is
burned
Assumes no trading, no banking, and no change to
the amount of coal burned
16Result of the CAMR Rank Adjustment (2) target
Hg capture further depends on how much mercury
is in the coal
Assumes no trading, no banking, and no change to
the amount or quality of coal burned
