In the letter dated May 10, 2019, the Division of Air Quality (DAQ) submitted amendments to Title 15A North Carolina Administrative Code (NCAC) 02D .0902 for EPA to review and approve as part of the State Implementation Plan (SIP). The DAQ is proposing to substantively revise 15A NCAC 02D .0902(e) and (f) to narrow the applicability of 15A NCAC 02D .0958 to only the Metrolina maintenance area for the 1997 8-hour ozone standard. The proposed revisions to 15A NCAC 02D .0902 would result in little to no increase in VOC emissions throughout North Carolina and would not interfere with on-going attainment or maintenance of any of the National Ambient Air Quality Standards (NAAQS). The DAQ has identified that the statewide applicability of 15A NCAC 02D .0958 is an unnecessary burden associated with permitting and compliance of facilities in areas outside the Metrolina maintenance area for the 1997 8-hour ozone standard. 

Please direct any further questions or comments concerning this SIP submittal to the Rule Development Branch Supervisor.
