Premise: In general, if that emission level is exceeded in 2018 or later, the trading program, which reflects the back-stop trading program already developed by the WRAP and is modeled after the new nationwide sulfur dioxide trading program, will require a separate set of allowances for affected EGUs in the WRAP State to be held covering emissions starting the third year after the level is exceeded.

Hypothesis: If that emission level is exceeded in 2018 or later, it won't require a separate set of allowances.
Relation: contradiction
