The Kentucky Division for Air Quality is requesting that the EPA propose approval of the following 

proposed administrative regulations by parallel processing for the purpose of expediting the adoption of these

significant impact levels, significant monitoring concentrations, and baseline dates for the implementation of 

the PM2.5 NAAQS. Also, the amendments adopt the significant emissions rates to determine NSR 

applicability for PM25 and P~h5 precursors. The amendments were filed with the Legislative Research
