# ACTION:

 Notice of availability, notice of comment period, notice of public workshops.

# SUMMARY:

The Federal Aviation Administration (FAA) is issuing this Notice of Availability to advise the public that a Draft Supplemental Environmental Assessment (DSEA) will be available for public review beginning November 22, 2005. The DSEA details the proposed modification to the Four Corner-Post Plan at Las Vegas McCarran International Airport and addresses the potential environmental impacts associated with its implementation. The DSEA presents the Purpose and Need for the proposed project, a comprehensive analysis of the alternatives to the proposed project, and studies the potential environmental impacts associated with the proposed modification to the Four Corner-Post Plan.

The Federal Aviation Administration (FAA) proposes to modify an existing departure procedure that was implemented as part of the Four Corner-Post Plan at McCarran International Airport (LAS), Las Vegas, Nevada, in October 2001. The Four Corner-Post Plan was developed and implemented to address growing airspace and air traffic control inefficiencies caused by increases in air traffic in the Las Vegas TRACON airspace. This Draft Supplemental Environmental Assessment (SEA) has been developed to assess the potential environmental impacts that may be associated with the proposed modification of the STAAV Area Navigation (RNAV) Standard Instrument Departure (SID) to accommodate eastbound departures from Runway 25.
