MRY Unit Unit 1 Unit 2 Average Hourly Mercury Emissions Value Achieved at Full Load (Sorbent Trap Data) 18 ppm MProve and Non-Brominated PAC 2,17 1.61 31. The Final Rule solely relies on the conclusion that brominated PAC improves mercury removal. 89 Fed. Reg. at 38547 (citing the Beyondthe-Floor Memorandum). Consequently, MRY purchased brominated PAC for the purpose of determining if that product would achieve improved mercury removal as compared to non-brominated PAC. Minnkota selected MRY 1 for this trial because its mercury emissions baseline rate was higher than MRY 2 in the results identified above. As shown below, the MRY 1 average mercury emissions rate was higher when injecting brominated PAC as compared with non-brominated PAC.
