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

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Texas on February 23, 2004. This revision concerns the Dallas-Fort Worth ozone nonattainment area. Specifically, EPA is approving incorporation of a Memorandum of Agreement (MOA) between the Texas Commission on Environmental Quality (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 (DFWIA) with emissions offsets in the amount of 0.18 tons per day (tpd) of nitrogen oxides (NO<INF>X</INF>) 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<INF>X</INF> 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 for the proposed DFWIA project. The rationale for the final approval action and other information are provided in this document.
