# ACTION:

Notice of Availability. 

# SUMMARY:

The Federal Aviation Administration (FAA) announces the availability of the Final Supplemental Environmental Assessment (FSEA), and Finding of No Significant Impact and Record of Decision (FONSI/ROD) for the proposed modification to the Four Corner-Post Plan at Las Vegas McCarran International Airport, Las Vegas, Nevada.

                        The FSEA and FONSI/ROD were prepared pursuant to the National Environmental Policy Act (NEPA) of 1969, as amended, FAA Order 1050.1E, “Environmental Impacts: Policies and Procedures,” and other applicable environmental laws and regulations. The FSEA and FONSI/ROD assess the effects of the relevant environmental impact categories for the proposed Federal action under consideration in the proposed modification of the STAAV Area Navigation (RNAV) Standard Instrument Departure (SID) to accommodate eastbound departures from Runway 25. The STAAV RNAV SID was implemented as part of the Four Corner-Post Plan at McCarran International Airport (LAS), Las Vegas, Nevada, in October 2001. The proposed Federal action is required to address the air traffic and airspace inefficiencies for departure traffic resulting from increased demand at LAS, and to recapture the efficiency that was lost                               ( print page 67950)                            from the reduction in the use of the right-turn procedure from Runway 25 as part of the 2001 LAS 4CP. Modification of the STAAV departure procedure to accommodate eastbound departures will provide an additional route for some eastbound departures, and reduce the time needed between successive departures, resulting in improved airspace efficiency and reduced departure delays.
