# SUPPLEMENTARY INFORMATION:

                    On March 2, 2007, Southwest submitted a request to FAA for approval to re-initiate scheduled passenger service at SFO commencing August 26, 2007. Southwest had served SFO until February 2001, but discontinued service. As required by Title 14 of the Code of Federal Regulations (14 CFR 119.51), Southwest applied to the FAA to amend Southwest's OpSpecs to include SFO, thereby authorizing Southwest to conduct scheduled SFO service. The request to the FAA detailed Southwest's startup plans, commencing on August 26, 2007, with 18 daily landing/take-off cycles (LTOs), which would produce emissions below the General Conformity de minimis thresholds, and contained other information for the FAA to conduct the environmental review required under the regulations implementing the National Environmental Policy Act (NEPA) (40 CFR parts 1500-1508), Section 176(c) of the Clean Air Act (CAA) (40 CFR 93.150*et seq.*), and by FAA Order 1050.1E                     *Environmental Impacts: Policies and Procedures.*                     FAA issued an OpSpec to Southwest for this initial level of operations accompanied by a NEPA environmental categorical exclusion determining that the 18 daily LTOs were below de minimis thresholds and were not regionally significant. Southwest wishes to grow their operations to 40 LTOs within 2 years.
