Approval and Promulgation of Air Quality Implementation Plans; Texas; Environmental Speed Limit Revision for the Dallas/Fort Worth 8-Hour Ozone Nonattainment Area
The Environmental Protection Agency (EPA) is approving a revision to the Texas State Implementation Plan (SIP) for the Dallas/ Fort Worth (DFW) ozone nonattainment area to recategorize a local environmental speed limit (ESL) control measure as a transportation control measure (TCM). The EPA is approving this SIP revision because it satisfies the requirements of sections 110 and part D of the Clean Air Act (CAA), and EPA's policy and guidance.
