^1^ Area sources are only subject to dioxin/furan emission limits.

^2^ New sources are those that commenced construction or reconstruction
after February 11, 1999.

^3^ Meeting these deadlines means the source must conduct its
performance test well in advance of the deadlines listed in columns VI
and VII.

^4^ There are no emission limits for Group 2 furnaces.
