Public Comment Period: Clean Air Act Section 110(l) Demonstration for Adoption of NC NOx SIP Call Rules into and Removal of CAIR from the NC SIP

Purpose

The North Carolina Department of Environmental Quality, Division of Air Quality (DAQ), hereby gives notice regarding its Pre-hearing Draft of the North Carolina Clean Air Act (CAA) Section 110(l) Noninterference Demonstration for Adoption of Revisions to 15A NCAC 02D .1400 NOx State Implementation Plan (SIP) Call Rules into, and Removal of 15A NCAC 02D .2400 Clean Air Interstate Rules from, the North Carolina SIP for Electricity Generating Units (EGUs) and Large Non-EGUs. The DAQ is proposing to revise its CAA Section 110 SIP for EGUs and large non-EGUs to (1) incorporate ground-level ozone season (May 1 – September 30) NOx SIP Call statewide budgets and reporting requirements, and (2) remove the Clean Air Interstate Rules because they no longer apply in North Carolina.
