Pre-hearing Draft of the North Carolina Clean Air Act Sections 193 and 110(l) noninterference demonstration for repeal of 15A NCAC 02D .1300, Oxygenated Gasoline Standard

The pre-hearing draft of the “North Carolina Clean Air Act Sections 193 and 110(l) noninterference demonstration for repeal of 15A NCAC 02D .1300, Oxygenated Gasoline Standard” was submitted to the EPA on July 14, 2017.  The Public Notice, Transmittal Letter, and Narrative are available through the following links:

The oxygenated gasoline standard rules codified at 15A NCAC 02D Section .1300 were adopted by North Carolina and included as a contingency measure in the limited maintenance plan for the Charlotte, Raleigh/Durham, and Winston-Salem metropolitan areas for the 8-hour carbon monoxide (CO) national ambient air quality standard (NAAQS). The rules include:

        15A NCAC 02D .1301, Purpose
        15A NCAC 02D .1302, Applicability
        15A NCAC 02D .1303, Definitions
        15A NCAC 02D .1304, Oxygen Content Standard
        15A NCAC 02D .1305, Measurement and Enforcement

The DAQ has identified the rules contained in sections 15A NCAC 02D .1300 as outdated and unnecessary because the CO limited maintenance plan for the Charlotte, Raleigh/Durham, and Winston-Salem areas ended in 2015 and EPA has revised the designation for each area to “attainment.” Also, the entire state of North Carolina has been in attainment with the CO NAAQS for over 20 years and ambient CO levels remain very low statewide. In addition, repealing the 15A NCAC 02D .1300 rules will not increase CO, nitrogen oxide, or total hydrocarbon vehicle exhaust emissions because the oxygenated gasoline standard rules were never implemented due to the success of the foundation control measures included in the plan. For these reasons, the DAQ concludes that repeal of the 15A NCAC 02D .1300 rules will not interfere with continued attainment or maintenance of any applicable NAAQS.

A public comment period will be open from Friday, July 14, 2017, through Monday, August 14, 2017. If a public hearing is requested, a separate notice will be published to announce the public hearing place, date, and time. Any persons wishing to comment may submit a written statement for inclusion in the record of proceedings regarding the Pre-hearing Draft of the “North Carolina Clean Air Act Sections 193 and 110(l) noninterference demonstration for repeal of 15A NCAC 02D .1300, Oxygenated Gasoline Standard.”
