Approval and Promulgation of Air Quality Implementation Plans; Texas; Memorandum of Agreement Between Texas Commission on Environmental Quality and the North Central Texas Council of Governments Providing Emissions Offsets to Dallas Fort Worth International Airport

Riepilogo

EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Texas Commission on Environmental Quality (TCEQ) on February 23, 2004. This revision concerns the Dallas/Fort Worth ozone nonattainment area. Specifically, EPA is proposing to approve the incorporation of a Memorandum of Agreement (MOA) between the TCEQ and the North Central Texas Council of Governments (NCTCOG) into the SIP. This MOA commits the NCTCOG to provide the Dallas-Fort Worth International Airport with emissions offsets in the amount of 0.18 tons per day (tpd) of nitrogen oxides (NO X ) and 0.04 tpd of volatile organic compounds (VOCs) in 2007 and to adjust the modeled 2015 on-road emission estimates to reflect an increase of 1.17 tpd of NO X and 0.26 tpd of VOCs, which must be accommodated in future transportation conformity determinations. This action is necessary in order for the Federal Aviation Administration (FAA) to address requirements under the general conformity regulations.
