For each . . . For which . . . Then you must . . .
1. Group 1 continuous process vent a. Not applicable i. Reduce emissions of total organic HAP by ≥98 percent by weight or to an outlet process concentration ≤20 ppmv as organic HAP or TOC by venting emissions through a closed-vent system to any combination of control devices (except a flare); or
ii. Reduce emissions of total organic HAP by venting emissions through a closed vent system to a flare; or
