The Federal Aviation Administration (FAA) has announced the availability of a Written Re-evaluation/Record of Decision (WR/ROD) for changes to the Las Vegas Metroplex Project's Final Environmental Assessment design for five flight procedures. These changes involve four procedures at McCarran International Airport and one at Henderson Executive Airport. The FAA has determined that these changes do not significantly alter environmental impacts, and thus, no supplement to the Final Environmental Assessment will be prepared. The WR/ROD and related documents are accessible to the public for review.
Simple Explanation
The FAA is making small changes to how airplanes take off and land at two airports in Las Vegas, and they checked to make sure these changes are okay for the environment. They found everything is fine, so there's no need for a big new study, and now people can look at the papers to see what they did.
