In a letter dated January 31, 2008, the Division of Air Quality (DAQ) submitted amendments to Chapter 15A North Carolina Administrative Code (NCAC) Section 02D .0519 for EPA to re-view and approve as part of the State Implementation Plan. The amendment in paragraph (a)(1) of the Rule deleted the provision to limit NO2 emissions from nitric acid manufacturing plants. The revision was made because no nitric acid plants existed at the time the amendment was adopted, and there are no plants currently operating in North Carolina. The EPA is in the process of acting on this SIP submission (NC 133), and has asked the DAQ to submit a noninterference demonstration that ensures the change will not interfere with attainment and maintenance of National Ambient Air Quality Standards (NAAQS).
In this noninterference demonstration, the DAQ concludes that there would be no emissions impact due to the rule change. The state’s ability to attain or maintain air quality standards will not be hindered and the removal of NO2 emissions control requirements from nitric acid manufacturing plants will not interfere with the attainment of any applicable NAAQS. The DAQ believes the requirements of Section 110(l) of the Clean Air Act have been met.
